The exhaust device 1000 may include an exhaust fan 1700, a fan motor (not illustrated), and a power module (not illustrated). The exhaust fan 1700 of the exhaust device 1000 may be located in the second flow path 30. The fan motor (not illustrated) of the exhaust device 1000 may be located at the second flow path 30 and may be located on the outer side surface of the second flow path 30 together with the power module (not illustrated). The exhaust device 1000 may include a separate power module (not illustrated) instead of receiving power a power module (not illustrated) of the heating apparatus 2000.

The exhaust fan 1700 may be connected to the fan motor (not illustrated), and the exhaust device 1000 may suck in fine particles by rotating the exhaust fan 1700 by driving the fan motor (not illustrated). The exhaust fan 1700 may be provided perpendicular to a direction in which air is discharged from the second flow path (a downward direction in FIG. 2).

The first flow path 20 and the second flow path 30 may be separated from each other and may be connected to each other by the user. Also, according to an embodiment of the disclosure, the first flow path 20, the second flow path 30, and the exhaust device 1000 may be sold together with the heating apparatus 2000 as components of the heating apparatus 2000.

The heating apparatus 2000 may open/close a plurality of aspiration hobs by using a plurality of valves.

According to an embodiment of the disclosure, identification information of the aspiration hob corresponding to the burner may be stored in the heating apparatus 2000. Accordingly, the heating apparatus 2000 may open at least one aspiration hob corresponding to the burner in operation. For example, as the first burner 15_1 operates, the heating apparatus 2000 may open the first aspiration hob 10_1 and the second aspiration hob 10_2 and may not open the third aspiration hob 10_3.

Also, according to an embodiment of the disclosure, identification information of the aspiration hob corresponding to the burner and the heating level may be stored in the heating apparatus 2000. Accordingly, the heating apparatus 2000 may open at least one aspiration hob corresponding to the burner in operation and the heating level of the burner in operation. For example, when the second burner 15_2 is operating at a heating level of 4, the heating apparatus 2000 may open only the third aspiration hob 10_3, and when the second burner 15_1 is operating at a heating level of 6, the heating apparatus 2000 may open the second aspiration hob 10_2 together with the third aspiration hob 10_3 and close the first aspiration hob 10_1.

Also, according to an embodiment of the disclosure, identification information of the aspiration hob corresponding to the burner, the heating level, and the food material may be stored in the heating apparatus 2000. Accordingly, the heating apparatus 2000 may open at least one aspiration hob corresponding to the burner in operation, the heating level of the burner in operation, and the food material being cooked in the burner in operation. For example, when the cooking material of the first burner 15_1 is soup and the first burner 15_1 is operating at a heating level of 7, the heating apparatus 2000 may open only the first aspiration hob 10_1 and close the other aspiration hobs, that is, the second aspiration hob 10_2 and the third aspiration hob 10_3. Also, when the food material of the first burner 15_1 is mackerel and the first burner 15_1 is operating at a heating level of 4, the heating apparatus 2000 may open the first aspiration hob 10_1 and the second aspiration hob 10_2.

The exhaust device 1000 may transmit the output RPM of the fan motor to the heating apparatus 2000 through the short-range wireless communication module 1310. The exhaust device 1000 may determine the output RPM of the fan motor based on the sensor value of the RPM sensor 2440 and periodically transmit the determined RPM to the heating apparatus 2000.

The heating apparatus 2000 may determine whether the filter needs to be replaced, based on the output RPM of the fan motor and the target RPM.

As foreign substances are accumulated in the filter 50, the amount of air passing through the filter 50 may decrease and thus the load on the fan motor may decrease. Thus, even when the same fan motor driving voltage is applied, the output RPM of the fan motor may increase as foreign substances are accumulated in the filter 50. Thus, in a case that a driving voltage corresponding to the target RPM is applied to the fan motor, when the steady-state RPM value of the fan motor increases from the target RPM to a reference RPM or more, the heating apparatus 2000 may determine that foreign substances are accumulated in the filter 50 by a reference amount or more and thus the filter needs to be replaced.

FIG. 10 illustrates a flowchart of a method by which a heating apparatus determines whether a filter needs to be replaced, according to an embodiment of the disclosure.

The threshold RPM may be the RPM of the fan motor output when contaminants are accumulated in the filter to the extent that the filter needs to be replaced and a driving voltage corresponding to the target RPM is applied thereto. The extent that the filter needs to be replaced may be experimentally determined.

The heating apparatus 2000 may obtain a threshold RPM corresponding to the target RPM. Also, the heating apparatus 2000 may determine whether the output RPM of the fan motor received from the exhaust device 1000 is equal to or greater than the obtained threshold RPM.

Based on determining that the output RPM of the fan motor is equal to or greater than the threshold RPM, the heating apparatus 2000 may determine that the filter needs to be replaced.

Also, the heating apparatus 2000 may determine the degree of contamination of the filter based on the ratio between the output RPM of the fan motor and the threshold RPM.

Also, the heating apparatus 2000 may provide a user interface for inputting information indicating that the filter has been replaced. For example, according to receiving a user input of long-touching a “replace filter” phrase 113, the heating apparatus 2000 may determine that the filter has been replaced by the user. Based on determining that the filter has been replaced, the heating apparatus 2000 may output information indicating that the filter does not need to be replaced, by turning off the LED 2510_1 corresponding to the filter replacement.

Referring to FIG. 12, the exhaust device 1000 may include an airflow sensor 2430. A detector of the airflow sensor 2430 may be located in the second flow path 30. The heating apparatus 2000 may determine whether the installation of the flow path or fan is abnormal, based on the sensor value of the airflow sensor 2430.

The flow path may include the first flow path 20 and the second flow path 30, and the first flow path 20 and the second flow path 30 may be separated from each other and reconnected to each other. The first flow path 20 and the second flow path 30 may be separate products or may be separately sold although they are a single product.

When the heating apparatus 2000 is initially installed, it may be necessary to perform an operation of connecting the heating apparatus 2000 with the first flow path 20 and connecting the first flow path 20 with the second flow path 30. Also, the second flow path 30 may include a fan.

As the distance between the heating apparatus 2000 and the fan increases, as the diameter of the flow path increases, as the distance between the connections between the flow paths increases, or as the curve of the flow path increases, the actual suction power may decrease even when the fan is operated at the same driving voltage. Accordingly, a recommended installation method for connecting the heating apparatus 2000 with the first flow path 20 or the first flow path 20 with the second flow path 30 may be predetermined. Also, the recommended installation method may include the standards of the first flow path 20 and the second flow path 30 suitable for the heating apparatus 2000. Thus, when the connection method between the heating apparatus 2000 and the first flow path 20 or between the first flow path 20 and the second flow path 30 is different from the recommended installation method or when the flow path is not of a predetermined standard, the actual suction power may decrease.

A measurement value of the airflow, which is generated by the fan when the fan motor is driven at a reference voltage after connecting the heating apparatus 2000 with the first flow path 20 and connecting the first flow path 20 with the second flow path 30 by the recommended installation method, may be stored in the heating apparatus 2000. Also, a threshold airflow value may be stored in the heating apparatus 2000. The threshold airflow value may be a measurement value of the airflow generated by the fan when the fan motor is driven at a reference voltage when the installation of the heating apparatus 2000 and the flow path deviates from the recommended installation method by a reference degree or more.

According to receiving of a user input for starting an installation abnormality check, the heating apparatus 2000 may transmit an installation abnormality check request to the exhaust device 1000 through the short-range wireless communication link.

The exhaust device 1000 may periodically detect an airflow value in the flow path.

In operation S1350, the exhaust device 1000 may determine whether there is an installation abnormality, based on the airflow value and the output RPM of the fan motor.

As the distance between the heating apparatus 2000 and the fan increases, as the diameter of the flow path increases, as the distance between the connections between the flow paths increases, or as the curve of the flow path increases, the actual suction power may decrease even when the fan is operated at the same driving voltage.

A measurement value of the airflow, which is generated by the fan when the fan motor is driven at a reference RPM after connecting the heating apparatus 2000 with the first flow path and connecting the first flow path with the second flow path by the recommended installation method, may be stored in the heating apparatus 2000.

The threshold airflow value may be a measurement value of the airflow generated by the fan when the fan motor is driven at a reference RPM when the installation of the heating apparatus 2000 and the flow path deviates from the recommended installation method by a reference degree or more.

Also, the load on the fan motor may increase or decrease as the installation of the flow path is different from the recommended installation method. As the load on the fan motor also increases or decreases, the output RPM of the fan motor may increase or decrease even when the same drive is applied to the fan motor.

An output RPM of the fan motor, which is obtained when the fan motor is driven at a reference driving voltage after connecting the heating apparatus 1000 with the first flow path and connecting the first flow path with the second flow path by the recommended installation method, may be stored in the exhaust device 2000.

According to an embodiment of the disclosure, the target RPM of the fan motor corresponding to the detected amount of fine particles may be stored in the heating apparatus 2000.

According to an embodiment of the disclosure, the target RPM of the fan motor corresponding to the amount of a type of fine particles may be stored in the heating apparatus 2000. For example, the target RPM of the fan motor may be stored corresponding to the amount of oil vapor, and the target RPM of the fan motor may be stored corresponding to the amount of odor particles.

Accordingly, the heating apparatus 2000 may obtain a target RPM of the fan motor based on the amount of fine particles detected through the fine particle sensor.

According to an embodiment of the disclosure, when more air is sucked in through the aspiration hob due to the driving of the fan motor, more fine particles per unit volume may be detected by the fine particle sensor even with the same amount of fine particles. Accordingly, the target RPM of the fan motor corresponding to the output RPM of the fan motor and the amount of fine particles may be stored in the heating apparatus 2000. In this case, the heating apparatus 2000 may obtain a target RPM of the fan motor corresponding to the detected amount of fine particles and the output RPM of the fan motor.

FIG. 22 illustrates a block diagram of a heating apparatus according to an embodiment of the disclosure.

As illustrated in FIG. 22, the heating apparatus 2000 according to an embodiment of the disclosure may be an induction heating apparatus 2000. The heating apparatus 2000 may include a heating module 2100, a sensor 2400, a processor 2200, a communication module 2300, an output module 2500, a memory 2600, an input interface 2700, and a light emitting device 2800. However, not all of the illustrated elements are essential elements. The heating apparatus 2000 may include more or fewer elements than the illustrated elements.

The heating module 2100 may include a driving module 2110 and a transmission coil 2011; however, the disclosure is not limited thereto. The driving module 2110 may receive power from an external power supply and supply a current to the transmission coil 2011 according to a driving control signal of the processor 2200. The driving module 2110 may include an electromagnetic interference (EMI) filter 2111, a rectification circuit 2112, an inverter circuit 2113, a distribution circuit 2114, a current sensing circuit 2115, and a driving processor 2116; however, the disclosure is not limited thereto.

The EMI filter 2111 may block a high-frequency noise included in AC power supplied from an external power supply (external source) and pass an AC voltage and an AC current of a predetermined frequency (e.g., 50 Hz or 60 Hz). A fuse and a relay for blocking an overcurrent may be arranged between the EMI filter 2111 and the external power supply. The AC power obtained when the high-frequency noise is filtered out by the EMI filter 2111 may be supplied to the rectification circuit 2112.

The rectification circuit 2112 may convert AC power into DC power. For example, the rectification circuit 2112 may convert an AC voltage (positive voltage or negative voltage) whose magnitude and polarity change with time into a DC voltage whose magnitude and polarity are constant and may convert an AC current (positive current or negative current) whose magnitude and direction change with time into a DC current whose magnitude is constant. The rectification circuit 2112 may include a bridge diode. For example, the rectification circuit 2112 may include four diodes. The bridge diode may convert an AC voltage whose polarity changes with time into a positive voltage whose polarity is constant and may convert an AC current whose direction changes with time into a positive current whose direction is constant. The rectification circuit 2112 may include a DC link capacitor. The DC link capacitor may convert a positive voltage whose magnitude changes with time into a DC voltage with a constant magnitude.

The inverter circuit 2113 may include a switching circuit for supplying or blocking a driving current to the transmission coil 2011 and a resonance circuit for generating a resonance together with the transmission coil 2011. The switching circuit may include a first switch and a second switch. The first switch and the second switch may be connected in series between a plus line and a minus line output from the rectification circuit 2112. The first switch and the second switch may be turned on or off according to a driving control signal of the driving processor 2116.

The inverter circuit 2113 may control a current supplied to the transmission coil 2011. For example, the magnitude and direction of a current flowing through the transmission coil 2011 may change according to the turn-on/off of the first switch and the second switch included in the inverter circuit 2113. In this case, an AC current may be supplied to the transmission coil 2011. An AC current in the form of a sine wave may be supplied to the transmission coil 2011 according to the switching operation of the first switch and the second switch. Also, as the switching period of the first switch and the second switch increases (e.g., as the switching frequency of the first switch and the second switch decreases), the current supplied to the transmission coil 2011 may increase and the strength of the magnetic field output by the transmission coil 2011 (the output of the heating apparatus 2000) may increase.
