The controller 180 may be electrically connected to each part in the first cooking apparatus 100, e.g., each part of the first cooker 190 or the user interface 110, to transmit a control signal in the form of an electrical signal to each of the parts in the first cooking apparatus 100 or receive an electrical signal transmitted from each of the parts. In this case, the controller 180 may be electrically connected to each of the parts using one or more of various communicators such as a circuit, a conducting wire, and a wireless communication network constructed inside the first cooking apparatus 100.

According to an embodiment, the controller 180 may include the cooker controller 181, a second cooking apparatus controller 182, and the user interface controller 189 as illustrated in FIG. 2.

The cooker controller 181 may generate a first control signal corresponding to a user command input through the user interface 110 and transmit the generated first control signal to the first cooker 190 to control the first cooker 190 such that the first cooker 190 may operate depending on the user command. According to an embodiment, the cooker controller 181 may generate the first control signal according to a user command input through the first inputter 131 to control the first cooker 190. In addition, the cooker controller 181 may also receive an electrical signal transmitted from a first sensor 170 or an electrical signal transmitted through the first communicator 120, e.g., a signal corresponding to a control command transmitted from a terminal device, generate the first control signal in response to the received signal, and transmit the first control signal to control the first cooker 190 as necessary.

The second cooking apparatus controller 182 may be designed to generate a second control signal corresponding to the user command input through the user interface 110 and transmit the second control signal to the first communicator 120, e.g., the first cooking apparatus communicator 121. The first communicator 120 may transmit the second control signal to the second cooking apparatus 200 through the wired and wireless communication networks, and the second cooking apparatus 200 may perform an operation corresponding to the second control signal. In this case, the second cooking apparatus controller 182 may generate the second control signal according to a user command input through the second inputter 132. Like the cooker controller 181, the second cooking apparatus controller 182 may generate the second control signal in response to an electrical signal transmitted from the first sensor 170 or an electrical signal transmitted through the first communicator 120 to control the second cooking apparatus 200 as necessary.

The user interface controller 189 is provided to control various types of operations of the user interface 110. For example, the user interface controller 189 may amplify, convert, or switch a signal input through the inputter 130, and transmit the signal to the cooker controller 181 or the second cooking apparatus controller 182.

In addition, the user interface controller 189 may determine which cooking apparatus a user command input through the user interface 110 is related to and may transmit an electrical signal corresponding to the user command to any one of the cooker controller 181 and the second cooking apparatus controller 182 according to a determined result to enable any one of the first cooking apparatus 100 or the second cooking apparatus 200 to operate according to the user manipulation. In this case, the user interface controller 189 may determine whether the user has input a command related to the first cooking apparatus 100 or has input a command related to the second cooking apparatus 200 depending on, for example, which of the first inputter 131 and the second inputter 132 of the inputter 130 has been manipulated.

In addition, in another example, the user interface controller 189 may control the display 140 of the user interface 110 based on various types of information or signals such as information on operation of the first cooker 190, information transmitted from the first sensor 170 or the first communicator 120, and an electrical signal output from the cooker controller 181 or the second cooking apparatus controller 182. Depending on the control by the user interface controller 189, the display 140 may emit light of a predetermined color or display one or more of a letter, a symbol, and a predetermined image. When the display 140 includes the first display 141 and the second display 142, the user interface controller 189 may separately transmit a control signal to each of the first display 141 and the second display 142, and accordingly, the first display 141 and the second display 142 may be controlled to independently display information on the first cooking apparatus 100 and information on the second cooking apparatus 200, respectively.

According to an embodiment, when the user interface controller 189 determines that there is an error in a user command input through the inputter 130, the user interface controller 189 may control an outputter such as the display 140 to display an error signal. For example, when a manipulation of the inputter 130 does not match a preset setting, the user interface controller 189 may control the display 140 to display an error message that requests that a command related to the cooking apparatuses 100 and 200 be input again. For example, when a signal output according to the manipulation of the inputter 130 is neither an electrical signal corresponding to a user command related to the first cooking apparatus 100 nor an electrical signal corresponding to a command related to the second cooking apparatus 200, the user interface controller 189 may check whether the signal corresponds to a command related to another cooking apparatus and, when the signal does not correspond thereto, control the display 140 to display an error message.

The controller 180 may be realized using one or more semiconductor chips and related parts, and the one or more semiconductor chips and the related parts are installed on a printed circuit board to control an overall operation of the first cooking apparatus 100. One or more of the cooker controller 181, the second cooking apparatus controller 182, and the user interface controller 189 described above may be realized by different semiconductor chips and related parts or may be realized by the same semiconductor chips and related parts. When the cooker controller 181, the second cooking apparatus controller 182, and the user interface controller 189 are realized by different semiconductor chips and related parts, the semiconductor chips and the related parts may be installed on different substrates inside the first cooking apparatus 100.

The first cooker 190 is provided to perform a cooking operation according to control by the controller 180, e.g., the cooker controller 181. The first cooker 190 may be realized by employing various parts depending on the type of the first cooking apparatus 100. For example, when the first cooking apparatus 100 is a microwave oven, the first cooker 190 may be realized using an electric heater, a magnetron, a power supplier, and the like. Moreover, the first cooker 190 may be realized by employing various parts that may be generally considered by a designer to realize a cooking function of a specific type of the first cooking apparatus 100.

According to an embodiment, the first cooking apparatus 100 may further include one or more first sensors 170. The first sensor 170 may sense an operation of the first cooking apparatus 100, output an electrical signal corresponding to the sensed operation, and transmit the electrical signal to the controller 180 through a circuit or a cable. The first sensor 170 may include one or more of a UV sensor, an infrared sensor, a visible light sensor, a heat sensor, a gas sensor, a magnetic sensor, and a pressure sensor. For example, the first sensor 170 may sense heat or smoke emitted from the first cooking apparatus 100, output an electrical signal corresponding to a sensed result, and transmit the electrical signal to the controller 180.

The first sensor 170 may be installed at one position of the first cooking apparatus 100 capable of suitably sensing an operation of the second cooking apparatus 200. For example, when the second cooking apparatus 200 is installed below the first cooking apparatus 100 and the first sensor 170 is a heat sensor, the first sensor 170 may be installed at the bottom surface of the first cooking apparatus 100 in a lower end direction to sense an operation of the second cooking apparatus 200. The first sensor 170 may be omitted according to an embodiment.

The controller 480 may control the first cooker 490, the fan driver 458a, and the first communicator 420 according to a user manipulation using the user interface 410.

According to an embodiment, the first cooker 490 may include an oscillator 491, an amplifier 492, and the microwave emitter 493. The oscillator 491 may generate microwave alternating current (AC) power of a predetermined frequency. The microwave AC power may be transmitted to the amplifier 492 through a transmission line such as a conducting wire. The amplifier 492 amplifies the received microwave AC power and transmits the amplified microwave AC power to the microwave emitter 493. The microwave emitter 493 may include the power feeder 494 and the antenna 495. The power feeder 494 may supply microwave power to the antenna 495. The antenna 495 may emit microwaves of a predetermined frequency to the inner portion of the heating compartment 404 according to the supplied microwave power to heat a heating target.

When information on whether the third cooking apparatus 600 is operating is transmitted to the controller 480 through the first communicator 420, the controller 480 may apply power to the fan driver 458a based on the received information to operate the fan driver 458a. Accordingly, the one or more suctioning fans 458b may start rotating, and smoke generated due to cooking using the third cooking apparatus 600 may be introduced into the exhaust flow channel 454 through the suction port 453. According to an embodiment, the controller 480 may also apply power to the fan driver 458a when information on whether the second cooking apparatus 500 is operating is transmitted thereto.

In addition, when a command related to the second cooking apparatus 500 or a command related to the third cooking apparatus 600 is input through the user interface 410, the controller 480 may apply power to the fan driver 458a to operate the fan driver 458a in response to the input command, thereby enabling smoke generated due to cooking using the third cooking apparatus 600 to be introduced into the exhaust flow channel 454 through the suction port 453. In other words, the controller 480 may predict that the second cooking apparatus 500 or the third cooking apparatus 600 will operate according to manipulation of the user interface 410 and operate the fan driver 458a even when information on an operation of the second cooking apparatus 500 or the third cooking apparatus 600 is not received.

In addition, the controller 480 may also apply power to the fan driver 458a according to a result sensed by the first sensor 470, a result sensed by a second sensor 569 provided in the second cooking apparatus 500, or a result sensed by a third sensor (not illustrated) provided in the third cooking apparatus 600 to operate the fan driver 458a. Accordingly, smoke generated due to cooking using the third cooking apparatus 600 may be introduced into the exhaust flow channel 454 through the suction port 453.

When a user command related to the second cooking apparatus 500 is input through the user interface 410, the controller 480 may generate a control signal corresponding to the input user command and transmit the generated control signal to the first communicator 420. The first communicator 420 may transmit the received control signal to a corresponding cooking apparatus, e.g., the second cooking apparatus 500. When the user interface 410 is able to receive a user command related to the third cooking apparatus 600, the controller 480 may transmit a control signal related to the third cooking apparatus 600 to the third cooking apparatus 600 through the first communicator 420.

In addition, the controller 480 may also control the user interface 410. For example, the controller 480 may control the display 440 of the user interface 410 to display information on the first cooking apparatus 400 or the second cooking apparatus 500. In addition, the controller 480 may also control the display 440 to display information on the third cooking apparatus 600.

In addition, the controller 480 may determine which cooking apparatus a user command input through the user interface 410 corresponds to. For example, when the first cooking apparatus selection button 411a is manipulated, the controller 480 may deem that a user command input through the inputter 411 is a user command related to the first cooking apparatus 400 and control the first cooker 490 as a result. In addition, in another example, when the second cooking apparatus selection button 411b is manipulated, the controller 480 may deem that a user command input through the inputter 411 is a user command related to the second cooking apparatus 500 and transmit a control signal to the second cooking apparatus 500 through the first communicator 420.

Hereinafter, an example in which the second cooking apparatus 500 is an oven will be described. An oven that will be described below may be a gas oven or an electric oven.

Positions of the first driver 712 and the second driver 713 may be switched with each other. For example, unlike FIG. 27, the second driver 713 may be disposed at a position of the first driver 712. In this case, the first driven portion 721 and the second driven portion 731 respectively corresponding to the first driver 712 and the second driver 713 may be installed at proper positions inside the front surface housing 705 and the rear surface housing 707.

In addition, according to an embodiment, the protrusion 712a or the groove 713a may be formed at both of the first driver 712 and the second driver 713. In addition, unlike the description above, a groove (not illustrated) may be formed at the first driver 712 and a protrusion may be formed at the second driver 713 according to an embodiment.

The ignition plug driver 720 and the ignition switch manipulation sensor 730 may be provided near the cam member 710.

The ignition plug driver 720 may drive the ignition plug according to the rotation of the first driver 712, and the ignition switch manipulation sensor 730 may sense an operation of the ignition switch according to an operation of the second driver 713.

The ignition plug driver 720 and the ignition switch manipulation sensor 730 may be designed to correspond to shapes of the first driver 712 and the second driver 713, respectively. Specifically, the ignition plug driver 720 and the ignition switch manipulation sensor 730 may have predetermined structures depending on whether the protrusion 712a or the groove 713a is formed at the ignition plug driver 720 and the ignition switch manipulation sensor 730.

According to an embodiment, the ignition plug driver 720 may include the first driven portion 721 and the first contact portion 725.

The first driven portion 721 is provided to be moved or be bent by the protrusion 712a provided at the first driver 712 according to the rotation of the first driver 712.

Specifically, according to an embodiment, the first driven portion 721 may include a main body 723 and a fixer 723h configured to fix the main body 723. The main body 723 is realized using a material having a predetermined degree of flexibility to be bent by a force applied from the outside and having elasticity to be restored to an original form thereof when the applied force disappears while being realized using a conductor such as a metal through which a current may flow.

According to an embodiment, as illustrated in FIG. 29A, the main body 723 may include a first portion 723a fixed by the fixer 723h and having a mounting groove 723i on which the first conducting wire 790 or a predetermined conducting wire connected to a power source, e.g., the third conducting wire 792, is mounted, a first bent portion 723b bent toward the cam member 710 and configured to connect an end of the first portion 723a to a second portion 723c, the second portion 723c configured to extend from the first bent portion 723b, a second bent portion 723d bent in a direction receding from the cam member 710 and configured to connect the second portion 723c to a third portion 723e, and the third portion 723e having one end connected to the second bent portion 723d. The third portion 723e is provided to come into contact with the outer surface of the first driver 712 by the first bent portion 723b and the second bent portion 723d. In addition, a contact terminal 722 is formed at a portion of the third portion 723e, e.g., the other end thereof. One or more of the first portion 723a to the third portion 723e may be bent or be moved according to the rotation of the first driver 712, and the contact terminal 722 formed at the third portion 723e may be moved toward a contact terminal 726 of the first contact portion 725 to come into contact with the contact terminal 726 of the first contact portion 725. The fixer 723h is provided to be fixed at an inside of the front surface housing 705 or the rear surface housing 707 to fix the main body 723.

The first contact portion 725 is provided to be fixed inside the front surface housing 705 or the rear surface housing 707 and may include the contact terminal 726 and an electrical connector 727.

When the first driven portion 721 is bent by the protrusion 712a of the first driver 712, the contact terminal 726 of the first contact portion 725 is provided to come into contact with the contact terminal 722 of the first driven portion 721. The first contact portion 725 may be realized using a conductor such as a metal through which a current may flow.

The electrical connector 727 may be provided to electrically connect the contact terminal 726 to the first conducting wire 790. A mounter 727a having a predetermined conducting wire mounted thereon may be provided at a portion of the electrical connector 727, and the predetermined conducting wire may include the first conducting wire 790. In this case, a conducting wire connected to the power source to receive a current provided from the power source may be mounted on the mounting groove 723i at the first portion 723a described above. According to an embodiment, the electrical connector 727 may be connected to the power source through the predetermined conducting wire. In this case, the first conducting wire 790 may be mounted on the mounting groove 723i at the first portion 723a. The electrical connector 727 may be realized using a conductor such as a metal through which a current may flow.

According to an embodiment, the ignition switch manipulation sensor 730 may include the second driven portion 731 and the second contact portion 735.

The second driven portion 731 may be moved or be bent by the groove 713a provided at the second driver 713 according to the rotation of the second driver 713.

Specifically, the second driven portion 731 may include a main body 733 and a fixer 733h configured to fix the main body 733. The main body 733 may be realized using a conductor such as a metal through which a current may flow. In this case, the conductor may be realized using a material such as copper having the predetermined degree of flexibility to be bent by a force applied from the outside and having elasticity to be restored to an original form thereof when the applied force disappears.

According to an embodiment, as illustrated in FIG. 29B, the main body 733 may include a fourth portion 733a fixed by the fixer 733h and having a mounting groove 733i on which the second conducting wire 791 or the third conducting wire 792 is mounted, a third bent portion 733b bent toward the cam member 710 and configured to connect an end of the fourth portion 733a to a fifth portion 733c, and the fifth portion 733c configured to extend from the third bent portion 733b. In this case, the third bent portion 733b is bent more sharply than the first bent portion 723b. The fifth portion 733c may include a fourth bent portion 733d bent in the direction receding from the cam member 710 and configured to connect the fifth portion 733c to a sixth portion 733e. In this case, the fourth bent portion 733d may be bent more sharply than the second bent portion 723d in the direction receding from the cam member 710. The fourth bent portion 733d, the fifth portion 733c near the fourth bent portion 733d, and the sixth portion 733e near the fourth bent portion 733d form a groove coupler 734 capable of being inserted into the groove 713a or being spaced apart from the groove 713a. The groove coupler 734 may enter the groove 713a or be detached from an inner portion of the groove 713a while moving along an outer surface of the groove 713a due to the rotation of the second driver 713. Accordingly, the main body 733 may be bent or be moved toward the second contact portion 735. The sixth portion 733e is provided between the fourth bent portion 733d and a fifth bent portion 733f, and the fifth bent portion 733f is bent toward the cam member 710 and is provided to connect the sixth portion 733e to a seventh portion 733g. A contact terminal 732 is formed at a portion of the seventh portion 733g, e.g., one end thereof. One or more of the fourth portion 733a to the seventh portion 733g may be bent or be moved according to the rotation of the second driver 713. Accordingly, the contact terminal 732 formed at the seventh portion 733g moves toward a contact terminal 736 of the second contact portion 735 to come into contact with the contact terminal 736 of the second contact portion 735. The fixer 733h is provided to be fixed at an inside of the front surface housing 705 or the rear surface housing 707 to fix the main body 733.

The second contact portion 735 is provided to be fixed inside the front surface housing 705 or the rear surface housing 707 and may include the contact terminal 736 and an electrical connector 737.

When the groove coupler 734 of the second driven portion 731 is bent by being detached from the groove 713a of the second driver 713, the contact terminal 736 of the second contact portion 735 is designed to come into contact with the contact terminal 732 of the second driven portion 731. The second contact portion 735 may be realized using a conductor such as a metal through which a current may flow.

The electrical connector 737 may be provided to electrically connect the contact terminal 736 to one or more of the second conducting wire 791 and the third conducting wire 792. A mounter 737a having one or more of the second conducting wire 791 and the third conducting wire 792 mounted thereon may be provided at a portion of the electrical connector 737. When the second conducting wire 791 is mounted on the mounting groove 733i at the fourth portion 733a, the third conducting wire 792 may be mounted on the mounter 737a of the electrical connector 727. Conversely, when the third conducting wire 792 is mounted on the mounting groove 733i at the fourth portion 733a, the second conducting wire 791 may be mounted on the mounter 737a of the electrical connector 737. The electrical connector 737 may be realized using a conductor such as a metal through which a current may flow.

FIG. 30 is a first view for describing a process of sensing an ignition switch operation according to rotation of a cam according to an embodiment of the present disclosure.

FIG. 31 is a second view for describing the process of sensing an ignition switch operation according to rotation of a cam according to an embodiment of the present disclosure.

Referring to FIG. 30, when the cam member 710 rotates, the first driver 712 and the second driver 713 also rotate, and the protrusion 712a of the first driver 712 and the groove 713a of the second driver 713 also move.

The protrusion 712a applies a pushing force to the third portion 723e of the main body 723 of the first driven portion 721 while rotating, and the main body 723 is bent or moved in the direction receding from the cam member 710. Accordingly, as illustrated in FIG. 31, the contact terminal 722 provided at the main body 723 comes into contact with the contact terminal 726 of the first contact portion 725. In this case, when a current is applied to the main body 723, the current applied to the main body 723 is transmitted to the first contact portion 725 through the two contact terminals 722 and 726. Conversely, when a current is applied to the first contact portion 725, the current applied to the first contact portion 725 is transmitted to the main body 723 through the two contact terminals 722 and 726. Accordingly, the first driven portion 721 and the first contact portion 725 are conducted and a current flows therebetween. Accordingly, a current provided through a conducting wire connected to the power source may be transmitted to the first conducting wire 790 through the first driven portion 721 and the first contact portion 725 and may be ultimately transmitted to the ignition plug 699. In this way, the ignition plug driver 720 may drive the ignition plug.

When the groove 713a of the second driver 713 rotates, the groove coupler 734 of the second driven portion 731 is detached from the groove 713a while moving along the outer surface of the groove 713a. Accordingly, the main body 733 of the second driven portion 731 is bent or moved in the direction receding from the cam member 710. Accordingly, as illustrated in FIG. 31, the contact terminal 732 provided at the main body 733 comes into contact with the contact terminal 736 of the second contact portion 735. Accordingly, the second driven portion 731 and the second contact portion 735 are conducted and a current flows therebetween. Since the second driven portion 731 is electrically connected to any one of the second conducting wire 791 and the third conducting wire 792, and the second contact portion 735 is electrically connected to the other one of the second conducting wire 791 and the third conducting wire 792, the second conducting wire 791 and the third conducting wire 792 are also electrically connected due to conduction of the second driven portion 731 and the second contact portion 735. When any one of the second conducting wire 791 and the third conducting wire 792 is connected to the third communicator 620 and the other one is connected to the power source configured to supply power as described above, the current supplied from the power source may be transmitted to the third communicator 620 via the second conducting wire 791 and the third conducting wire 792. Accordingly, since whether the ignition switch 630 is operating may be transmitted to the third communicator 620, the ignition switch manipulation sensor 730 may sense whether the ignition switch 630 is operating.

Although the ignition plug driver 720 and the ignition switch manipulation sensor 730 of the ignition switch assembly 700 have been described above, functions or operations thereof may be switched with each other. For example, when the second conducting wire 791 and the third conducting wire 792 are connected to the ignition plug driver 720, the ignition plug driver 720 may serve as the ignition switch manipulation sensor 730. In addition, when the ignition switch manipulation sensor 730 is connected to the first conducting wire 790 and a conducting wire extending from the power source, e.g., the third conducting wire 792, the ignition switch manipulation sensor 730 may serve as the ignition plug driver 720.

FIG. 32 is a first view for describing opening and closing of the gas supply assembly according to an embodiment of the present disclosure.

FIG. 33 is a second view for describing the opening and closing of the gas supply assembly according to an embodiment of the present disclosure.

Referring to FIG. 26, the gas supply assembly 800 may include a gas exhaust 810 configured to suction combustion gas, a gas outlet 820 configured to discharge combustion gas, and the body 814 configured to connect the gas exhaust 810 to the gas outlet 820 and enable or block a flow of combustion gas.

The gas exhaust 810 may be coupled to the first gas pipe 801 from which combustion gas is provided and may include the gas suction hole 811 connected to the gas discharge hole of the first gas pipe 801 to enable the combustion gas to enter the body 814. The gas exhaust 810 may be provided so that the gas suction hole 811 faces upward, and the first gas pipe 801 may be seated on top of the gas exhaust 810.

A coupler 812 to be coupled to an inside of the exterior housing 601 of the third cooking apparatus 600 may be formed at a side surface of the gas exhaust 810. The coupler 812 is fixed to an inside of an upper surface of the exterior housing 601 using a screw, a bolt, or the like to enable the gas supply assembly 800 to be stably installed at the third cooking apparatus 600.

An extension 813 configured to extend from the gas exhaust 810 and form a flow passage of combustion gas may be additionally formed between the gas exhaust 810 and the body 814.

The body 814 may be connected to the gas exhaust 810 and the gas outlet 820. For example, an upper portion of the body 814 may be connected to the gas exhaust 810, and a rear surface of the body 814 may be connected to the gas outlet 820.

Referring to FIGS. 32 and 33, the gas opener-and-closer 830 may be provided inside the body 814. The gas opener-and-closer 830 may have a shape of a pipe body 832 having an opening 831 formed at one side surface and the other portions sealed, and the pipe body 832 is rotatably provided inside the body 814. The portion 830a of the gas opener-and-closer 830 may be coupled to an end of the second driver 713 of the cam member 710 to rotate inside the body 814 according to the rotation of the cam member 710.

Referring to FIG. 32, when the opening 831 faces a side surface of the body 814, the opening 831 is closed by a side frame of the body 814. In this case, a sealed portion of the pipe body 832 faces the gas exhaust 810 and blocks a passage 815 in the gas exhaust 810, thereby preventing combustion gas that has entered the gas exhaust 810 from flowing to the gas discharge hole 821. Accordingly, the gas supply assembly 800 may prevent the combustion gas from flowing to the burner 691.

When the opening 831 faces the upper surface of the body 814 as illustrated in FIG. 33, the passage 815 in the gas exhaust 810 is open, and the gas suction hole 811 and the gas discharge hole 821 are connected to each other to enable combustion gas to flow therethrough. Combustion gas that has entered through the gas suction hole 811 passes through the passage 815, enters the gas opener-and-closer 830, moves to the gas discharge hole 821 along a passage formed at the gas outlet 820, and is transmitted to the burner 691 along the second gas pipe 802. In this way, the gas supply assembly 800 may enable the combustion gas to be transmitted to the burner 691.

FIG. 34 is a view for describing a flow of controlling the third cooking apparatus according to an embodiment of the present disclosure.

FIG. 35 is a first view for describing an operation of the first cooking apparatus in response to a cooking operation of the third cooking apparatus according to an embodiment of the present disclosure.

FIG. 36 is a second view for describing an operation of the first cooking apparatus in response to the cooking operation of the third cooking apparatus according to an embodiment of the present disclosure. In FIG. 34, only elements required for convenience of describing the flow of controlling the third cooking apparatus are briefly illustrated.

Referring to FIG. 34, the third cooking apparatus 600 may include the first gripping portion 631, the third communicator 620, the ignition plug 699, the ignition plug driver 720, and the ignition switch manipulation sensor 730.

Referring to FIG. 35, when the user manipulates the first gripping portion 631, the ignition plug driver 720 outputs an electrical signal according to the rotation of the first gripping portion 631 and transmits the electrical signal to the ignition plug 699 as described above. Accordingly, the burner 691 is ignited, and a container 9 seated on the container mount 689 near the burner 691 is heated.

In addition, an electrical signal is also output by the ignition switch manipulation sensor 730 according to the rotation of the first gripping portion 631, and the electrical signal is transmitted to the third communicator 620 through a transmitter such as a conducting wire. The electrical signal may be converted into a digital signal by an analog-digital converter or may be amplified by an amplifier before being transmitted to the third communicator 620.

The third communicator 620 may convert the electrical signal according to the sensed manipulation of the ignition switch 630 into a communicable form and transmit the electrical signal to the first communicator 420 of the first cooking apparatus 400.

The first communicator 420 of the first cooking apparatus 400 receives the electrical signal according to the sensed manipulation of the ignition switch 630, and transmits the received electrical signal to the controller 480. The controller 480 may apply power to the fan driver 458a based on received information to operate the fan driver 458a. Accordingly, as illustrated in FIG. 36, smoke 8 generated from the container 9 during a cooking process flows toward the bottom surface of the first cooking apparatus 400 and is suctioned by the exhaust 450 provided at the bottom surface of the first cooking apparatus 400 to be emitted to the outside.

According to an embodiment, when the third cooking apparatus 600 is operated, the third cooking apparatus 600 may sense heat near the burner 691 using a sensor (not illustrated) and transmit information on the sensed heat to the first cooking apparatus 400 to enable the controller 480 of the first cooking apparatus 400 to operate the fan driver 458a based on transmitted information on a temperature near the burner 691.

In addition, the third cooking apparatus 600 may include the stop command inputter 650. The stop command inputter 650 may output an electrical signal according to a user manipulation and transmit the output electrical signal to the third communicator 620, and the third communicator 620 may convert the received electrical signal into a communicable form and transmit the electrical signal to the second communicator 520 of the second cooking apparatus 500.

The second communicator 520 of the second cooking apparatus 500 may receive an electrical signal according to manipulation of the stop command inputter 650, and the received signal may be transmitted to the second cooker 590, a power source configured to apply an electrical signal to the second cooker 590, or a switch configured to connect the second cooker 590 to the power source to temporarily interrupt or non-temporarily stop operation of the second cooker 590.

In addition, the third cooking apparatus 600 may include the operation state display 660, and the operation state display 660 may display a state of the second cooking apparatus 500. In this case, the third communicator 620 may receive an electrical signal transmitted from the second communicator 520 of the second cooking apparatus 500 corresponding to a state of the second cooking apparatus 500, and may directly transmit the received electrical signal to the operation state display 660 or transmit the received electrical signal to a separate controller (not illustrated) provided at the third cooking apparatus 600 to enable the operation state display 660 to emit predetermined light or display a predetermined image according to the state of the second cooking apparatus 500.

FIG. 37 is a perspective view of a third cooking apparatus according to an embodiment of the present disclosure.

Referring to FIG. 37, a third cooking apparatus 900 may be an electric stove. In this case, the cooking apparatus 900 may be provided above the second cooking apparatus 500, e.g., an oven. According to an embodiment, the third cooking apparatus 900 may be separately manufactured from the second cooking apparatus 500 and then seated on the second cooking apparatus 500, or may be integrally formed with the second cooking apparatus 500. When the third cooking apparatus 900 and the second cooking apparatus 500 are integrally formed, the third cooking apparatus 900 may be manufactured to share an exterior housing with the second cooking apparatus 500.

The third cooking apparatus 900 may include an exterior housing 901, a cooking plate 902 provided at an upper surface of the exterior housing 901, and a plurality of burners 903 to 905 realized by heating coils provided inside the cooking plate 902.

A single induction heating coil may be installed for each of the guide marks M1, M2, and M3, or a plurality of induction heating coils may be installed.

An induction heating coil may have a circular or elliptical shape, and a magnetic field changing over time is induced inside the induction heating coil when AC is supplied to the induction heating coil. The magnetic field generated by the induction heating coil and changing over time passes through a bottom surface of a cooking container seated on the guide marks M1, M2, and M3. Here, a current rotating about the magnetic field, i.e., an eddy current, is generated on the bottom surface of the cooking container. When the eddy current is generated at the cooking container, electrons generate heat by colliding with atoms forming the cooking container due to the eddy current, and the cooking container is heated by the generated heat.

In this way, the third cooking apparatus 900, which is an electric stove, may heat the cooking container.

Various types of parts may be installed inside the exterior housing 901 of the third cooking apparatus 900. For example, not only the induction heating coil described above, but also various types of parts for performing an operation of the third cooking apparatus 900, e.g., an operation of applying a current to the induction heating coil, a semiconductor chip and related parts for controlling such an operation, and a substrate having the semiconductor chip and the like installed thereon may be provided inside the external housing 901. In addition, a communication module configured to serve as a communicator may be installed inside the external housing 901, and the communication module may communicate with one or more of the first cooking apparatus 400 and the second cooking apparatus 500. The communication module may be realized using a substrate, a communication chip mounted on the substrate, an antenna, etc.

The third cooking apparatus 900 may acquire information on an operation of the third cooking apparatus 900. For example, the third cooking apparatus 900 may detect a current being applied to an induction heating coil or measure heat around the burners 903 to 905 to acquire the information on the operation of the third cooking apparatus 900.

As described above, the third cooking apparatus 900 may transmit the acquired information on the operation of the third cooking apparatus 900 in the form of an electrical signal to the controller 480 of the first cooking apparatus 400 through the communication module, and the controller 480 of the first cooking apparatus 400 may operate the fan driver 438a based on the information transmitted from the third cooking apparatus 900. Accordingly, smoke generated in the container during a cooking process using the third cooking apparatus 900 flows toward the bottom surface of the first cooking apparatus 400 and is suctioned by the exhaust 450 provided at the bottom surface of the first cooking apparatus 400 to be emitted to the outside.

In addition, the third cooking apparatus 900 may further include a user interface 910. The user interface 910 may display information on the third cooking apparatus 900 or display an operation related to the second cooking apparatus 500. Specifically, the user interface 910 of the third cooking apparatus 900 may provide information on a state of the second cooking apparatus 500 to the user using a lighting device such as an LED lamp or various types of display panels. In addition, the user interface 910 may also receive a stop command related to the second cooking apparatus 500. Information provided through the user interface 910 or a user command input through the user interface 910 may be transmitted between the second communicator 520 provided at the second cooking apparatus 500 and the communicator provided at the third cooking apparatus 900.

FIG. 38 is a view illustrating an example of a cooking apparatus controlling system in which the first cooking apparatus is a microwave oven and the second cooking apparatus is an oven according to an embodiment of the present disclosure.

Hereinafter, a method of controlling a cooking apparatus according to various embodiments will be described with reference to FIGS. 40, 41, and 42.

Methods illustrated in FIGS. 40, 41, and 42 relate to a method in which one or more of a plurality of cooking apparatuses are used to control one or more other cooking apparatuses when the plurality of cooking apparatuses are provided. Hereinafter, it will be assumed that two or three cooking apparatuses are provided, and each of the cooking apparatuses will be referred to as a first cooking apparatus, a second cooking apparatus, and a third cooking apparatus. According to an embodiment, the number of cooking apparatuses may be two or four or more.

Types of a first cooking apparatus, a second cooking apparatus, and a third cooking apparatus may vary depending on a designer's choice. For example, the first cooking apparatus may be one or more of an electric oven, a gas oven, and a microwave oven, and the second cooking apparatus may be one or more of the electric oven, the gas oven, and the microwave oven. The third cooking apparatus may be one or more of the electric oven, the gas oven, the microwave oven, a gas stove, and an electric stove. The first cooking apparatus, the second cooking apparatus, and the third cooking apparatus may be different types of cooking apparatuses. In addition, according to an embodiment, at least two of the first cooking apparatus, the second cooking apparatus, and the third cooking apparatus may be the same type of cooking apparatus, or all of the first cooking apparatus, the second cooking apparatus, and the third cooking apparatus may be the same type of cooking apparatus.

At least two of the first cooking apparatus, the second cooking apparatus, and the third cooking apparatus are designed to be able to communicate with each other, and the communication may be realized using one or more of a wired communication network or a wireless communication network. The wired communication network may be realized using a cable such as a pair cable, a coaxial cable, an optical fiber cable, or an Ethernet cable, and the wireless communication network may be realized using a wireless LAN, a Wi-Fi, Bluetooth, ZigBee, CAN communication, WFD, UWB communication, IrDA communication, Bluetooth low energy communication, NFC, and various types of mobile communication technologies based on 3GPP, 3GPP2, and Wi-Max.

One or more of the first cooking apparatus, the second cooking apparatus, and the third cooking apparatus may communicate with a separate terminal device, e.g., a smartphone or a laptop computer, through a wired communication network or a wireless communication network, and receive a user command from the terminal device or transmit information on one or more of the first cooking apparatus, the second cooking apparatus, and the third cooking apparatus to the terminal device.

FIG. 40 is a flowchart of a method of controlling a cooking apparatus according to an embodiment of the present disclosure.

Although a first cooking apparatus includes a user interface and a controlling device, e.g., a central processing unit (CPU) or an MCU, configured to control the first cooking apparatus and a second cooking apparatus, the second cooking apparatus may not be equipped with a user interface or a controlling device. According to an embodiment, the second cooking apparatus may include a simple level of a user interface, e.g., a lighting device configured to display a current state and the like.

Referring to FIG. 40, first, a user command may be input through a user interface of a first cooking apparatus at operation S1000. Here, the user command may include various commands such as commands related to starting cooking, stopping cooking, ending cooking, setting a cooking time, changing the cooking time, scheduling cooking, setting a cooking temperature, selecting an operation mode of a second cooking apparatus, and cleaning the second cooking apparatus.

The first cooking apparatus may determine whether the input user command is related to the first cooking apparatus or the second cooking apparatus at operations S1010 and S1030. In this case, the first cooking apparatus may determine what the input user command is related to according to whether the user interface is set to receive a command related to the second cooking apparatus or according to which one of various inputters, e.g., a physical button and a touch sensor, provided at the user interface has been manipulated.

When it is determined that a user command related to the first cooking apparatus has been input (YES to S1010), the first cooking apparatus may perform an operation corresponding to the user command according to the input user command. For example, the first cooker provided at the first cooking apparatus may start operating to perform a cooking operation at operation S1020.

When it is determined that a user command related to the second cooking apparatus has been input (YES to S1030), the first cooking apparatus may convert the input user command into a communicable form and transmit the user command to the second cooking apparatus through the wired and wireless communication networks described above at operation S1040.

When the user command is neither a command related to the first cooking apparatus nor a command related to the second cooking apparatus, e.g., when a command not corresponding to preset settings is input, the first cooking apparatus may output an error signal at operation S1080. Here, the error signal may include, for example, a message that requests that a command be re-input.

The second cooking apparatus receives the user command transmitted from the first cooking apparatus and starts an operation according to the received user command at operation S1050. For example, the second cooker of the second cooking apparatus may start operating according to the user command and cook a heating target at a predetermined temperature.

According to an embodiment, the second cooking apparatus may also transmit information on a state of the second cooking apparatus to the first cooking apparatus to be displayed to the user at operation S1060. The transmission of the information may be performed during a cooking operation or even when the cooking operation is not being performed. Here, the information on the state of the second cooking apparatus may include whether the second cooking apparatus is operating, an elapsed cooking time, a temperature of the second cooking apparatus, whether cooking has ended, whether a failure or an error has occurred in the second cooking apparatus, and various other types of information on the second cooking apparatus.

Upon receiving the information on the state of the second cooking apparatus, the first cooking apparatus may display the received information through the user interface at operation S1070. In this case, the first cooking apparatus may use a single display capable of selectively displaying a state related to the first cooking apparatus and a state related to the second cooking apparatus to display the information on the state of the second cooking apparatus. In addition, the first cooking apparatus may use a plurality of displays capable of respectively displaying a state related to the first cooking apparatus and a state related to the second cooking apparatus to display information on the state of the second cooking apparatus. For example, when the display includes a first display and a second display, the first cooking apparatus may use the second display to display a state related to the second cooking apparatus to be provided to the user. In this case, the first display may display a state related to the first cooking apparatus.

In this way, the user may use a separate cooking apparatus to control another cooking apparatus or be notified of a state related to the other cooking apparatus. When the first cooking apparatus is an OTR microwave oven with a user interface provided at an eye level of the user, the user may acquire information on various cooking apparatuses and control the various cooking apparatuses through the OTR microwave oven more comfortably without changing his or her posture, thereby improving convenience of the user.

FIG. 41 is a flowchart of a method of controlling a cooking apparatus according to an embodiment of the present disclosure.

Referring to FIG. 41, first, a second cooking apparatus may start operating at operation S1100. In this case, the second cooking apparatus may start a predetermined operation according to a user command input through the user interface of the first cooking apparatus described above.

When the second cooking apparatus starts operating, one or more of the second cooking apparatus and a third cooking apparatus may display information on the operation of the second cooking apparatus at operation S1110. In this case, the third cooking apparatus may be a cooking apparatus installed above the second cooking apparatus. For example, the second cooking apparatus may be an oven such as an electric oven and a gas oven, and the third cooking apparatus maybe a gas stove or an electric stove installed above the oven.

The displaying of the information on operation of the second cooking apparatus may be performed by an operation state display provided at one or more of the second cooking apparatus and the third cooking apparatus, and the operation state display may be realized using various types of lighting devices capable of emitting light of a predetermined color such as an LED lamp, a fluorescent lamp, a UV lamp, a halogen lamp, a mercury lamp, a sodium lamp, and an incandescent lamp. In this case, to simplify an inner structure of the second cooking apparatus or the third cooking apparatus, a separate controlling device configured to control the operation state display may not be provided inside the second cooking apparatus and the third cooking apparatus.

According to an embodiment, a stop command inputter configured to temporarily interrupt or non-temporarily stop an operation of the second cooking apparatus may be provided at one or more of the second cooking apparatus and the third cooking apparatus.

When the stop command inputter is manipulated (YES to S1120), the second cooking apparatus temporarily interrupt or non-temporarily stops the operation at operation S1130. When the stop command inputter is provided at the third cooking apparatus, the third cooking apparatus may transmit an electrical signal generated according to the manipulation of the stop command inputter or a signal corresponding thereto to the second cooking apparatus through wired and wireless communication networks, and the second cooking apparatus stops an operation in progress, e.g., a cooking operation, based on the received signal.

When the stop command inputter is not manipulated (NO to S1120), the second cooking apparatus keeps performing the operation in progress without stopping the operation S1140.

FIG. 42 is a flowchart of a method of controlling a cooking apparatus according to an embodiment of the present disclosure.

Meanwhile, a first cooking apparatus may operate according to whether a third cooking apparatus is operating. For example, when the third cooking apparatus is a gas stove or an electric stove, and the first cooking apparatus is an OTR microwave oven, an exhaust provided at a lower end of the first cooking apparatus may operate according to an operation of the third cooking apparatus. Hereinafter, a method of controlling a cooking apparatus according to an embodiment in a case in which the third cooking apparatus is a gas stove and includes an ignition switch configured to ignite a burner of the gas stove will be described.

In a case in which a gripping portion of an ignition switch is designed to rotate together with a cam member, when the gripping portion of a third cooking apparatus rotates, the cam member also rotates due to the rotation of the gripping portion at operation S1200 as illustrated in FIG. 42. Here, the cam member may have a first driver and a second driver. An ignition plug driver may drive an ignition plug according to an operation of the first driver, and an ignition switch manipulation sensor may sense an operation of an ignition switch according to an operation of the second driver.

For example, when the cam member rotates, the second driver rotates, and a driven portion of the ignition switch manipulation sensor provided to abut the second driver moves as a result at operation S1210.

The driven portion moves toward a contact portion to come into contact with the contact portion. When the driven portion and the contact portion come into contact with each other, the driven portion and the contact portion are conducted and an electrical signal may be transmitted therebetween at operation S1220. Accordingly, an electrical signal introduced into the ignition switch manipulation sensor may be transmitted to a third communicator provided at the third cooking apparatus. In this way, whether the ignition switch has been manipulated may be sensed.

The third communicator may transmit the electrical signal to a first communicator of the first cooking apparatus at operation S1230. In this case, the third communicator may be designed to convert the electrical signal into a communicable form, and the first communicator of the first cooking apparatus may be designed to invert the converted signal to acquire the original electrical signal.

The first cooking apparatus, particularly a controlling device of the first cooking apparatus, may determine that the third cooking apparatus has started operating based on the received electrical signal at operation S1240.

Then, the controlling device generates a control signal related to a fan driver of the exhaust of the first cooking apparatus and transmits the generated control signal to the fan driver to rotate a fan provided toward the third cooking apparatus, thereby suctioning smoke generated due to a cooking operation of the third cooking apparatus through a suction hole of the exhaust at operation S1250. Consequently, the first cooking apparatus may automatically perform a smoke suctioning operation according to the operation of the third cooking apparatus.

The methods of controlling a cooking apparatus according to the embodiments described above may be realized in the form of a program that may be executed through various computer means. Here, the program may include a program command, a data file, a data structure, etc., alone or in a combination. Here, the program may be designed and produced using, for example, a machine language code generated by a compiler as well as a high-level language code that may be executed by a computer using an interpreter and the like. In addition, the program may be a program exclusively designed to realize the methods of controlling a cooking apparatus described above, or may be a program realized using various types of functions or definitions already known to and usable by those of ordinary skill in the computer software field.

A program for realizing the methods of controlling a cooking apparatus described above may be recorded in a computer readable recording medium.
