ICE MAKING APPARATUS AND REFRIGERATOR COMPRISING THE SAME
Provided are an ice maker and a refrigerator including the same. An ice maker is mounted on a rear side of a door. Flooding of water stored in an ice tray is prevented by a tray cover. Also, an ice bank storing ice made from the ice maker is taken in and out through a home bar provided to the door. Therefore, reduction in the storage capacity of the refrigerator is minimized, and simultaneously, the ice can be easily taken out.
The present disclosure relates to a refrigerator, and more particularly, to an ice maker provided to a refrigerator to make ice and the refrigerator having the same.
BACKGROUND ARTAn ice maker for making ice is provided to a refrigerator brought to the market recently. The ice maker is an apparatus for making ice automatically or manually. As an example of the ice maker, there is an ice maker including a plurality of ice cubes for making ice, and an ice tray twisted for separating made ice from the ice cubes. The ice made from the ice maker is stored in an ice bank.
However, according to the above-described related art ice maker, there are the following limitations.
First, the related art ice maker is installed inside a storage space of the refrigerator in general. Therefore, a storage capacity of the refrigerator substantially reduces by the volume of the ice maker.
Also, as described above, in case of the related art ice maker including the ice tray, there is a possibility that water stored in the ice cubes falls down to an outside by external impact before the water is frozen. For example, the water stored in the ice cubes may flood into an outside, i.e., the storage space of the refrigerator by an impact generated during a process of opening/closing a refrigerator door.
Furthermore, the storage space should be opened by opening the refrigerator door to use the ice stored in the ice bank. Therefore, using the ice may be inconvenient.
DISCLOSURE OF INVENTION Technical ProblemEmbodiments provide an ice tray configured to minimize reduction in a storage capacity of a refrigerator, and the refrigerator including the same.
Embodiments also provide an ice tray configured to minimize a phenomenon that water for making ice floods into an outside during a process of opening/closing a refrigerator door, and the refrigerator including the same.
Technical SolutionIn one embodiment, an ice maker includes: an ice tray rotatably installed on a rear side of a refrigerator door, and including ice cubes for making ice; and a tray cover rotating in cooperation with rotation of the ice tray to selectively open/close the ice cubes.
In another embodiment, an ice maker includes: a support frame mounted on a rear side of a refrigerator door; an ice tray rotatably installed to the support frame, and storing water for making ice; and a tray cover rotatably installed in relative to the ice tray, and preventing the water stored in the ice tray from flooding.
In further another embodiment, a refrigerator includes: a main body including a storage space; a door for selectively opening/closing the storage space; and an ice maker according to one of claims 1 to 17, mounted on a rear side of the door
Advantageous EffectsAccording to the present disclosure, reduction in a storage capacity of a refrigerator is minimized, and simultaneously, water for making ice is prevented from flooding to an outside, and ice can be easily taken in and out.
An ice maker of the present disclosure will now be made in detail according to the embodiment thereof with reference to the accompanying drawings.

Meanwhile, a home bar 6 is provided to the freezing chamber door 4 (referred to as a door hereinafter). The home bar 6 is designed for taking in and out food without opening the door 4 to open the freezing chamber 2. The home bar 6 includes a home bar housing 8 and a home bar door 7. The home bar housing 8 is provided on the rear side of the door 4. A storage space for storing food is formed between the rear side of the door 4 and the inner side of the home bar housing 8. Also, the upper end of the home bar door 7 vertically rotates around the lower end of the home bar door 7 at the door 4 to selectively open/close the home bar housing 8.
Also, an ice maker 10 is mounted on the rear side of the door 4. The ice maker 10 is designed for making ice, and detailed description thereof will be described below.
An ice bank 60 is installed on the rear side of the door 4 that corresponds to a portion below the ice maker 10 such that the ice bank 60 can be taken in and out. The ice bank 60 stores ice made by the ice tray 30. The ice bank 60 is taken out from the rear side of the door 4 through the home bar 6.
Referring to
The support frame 20 is formed in a rectangular frame shape. A mounting part 21 for being mounted onto the rear side of the door 4 is provided on the upper surface of one of the long sides of the support frame 20. Support holes 23 for rotation of the ice tray 30 are formed in the short sides of the support frame 20. A hooking threshold (not shown) is provided on one of the short sides of the support frame 20. The hooking threshold horizontally supports the ice tray 30, and simultaneously, allows the ice tray 30 that has rotated by a predetermined angle to be twisted. Since the hooking threshold is an obvious structure in a related art twisting type ice maker, detailed description thereof is omitted.
Also, a stopper protrusion 25 is provided to one of the long sides of the support frame 20. The stopper protrusion 25 allows the tray cover 40 to rotate in relative to the ice tray 30. For this purpose, the front end of the stopper protrusion 25 is so located as to deviate from the rotation trace of the ice tray 30 but overlap the rotation trace of the tray cover 40. Therefore, the stopper protrusion 25 does not interfere with rotation of the ice tray 30 but interferes with rotation of the tray cover 40.
The ice tray 30 is formed in a rectangular shape corresponding to the inside of the support frame 20. The ice tray 30 includes a plurality of ice cubes 31 storing water for making ice. Rotational shafts 33 are provided to the short sides of the ice tray 30, respectively. Each rotational shaft 33 is inserted into and supported by the support hole 23.
The tray cover 40 substantially prevents the water stored in the ice cubes 31 from flooding into an outside. For this purpose, the tray cover 40 selectively opens/closes the ice tray 30, more specifically, the ice cubes 31. In an embodiment, the tray cover 40 is formed in a semi-cylindrical corresponding to the rotation trace of the ice tray 30.
A water supply opening 41 is provided to the tray cover 40. The water supply opening 41 is designed for storing water in the ice cubes 31. The water supply opening 41 is formed by cutting a portion of the tray cover 40. The projection of the water supply opening 41 overlaps at least a portion of all the ice cubes 31.
A contact rib for selectively contacting the upper edge of the ice tray 30 is provided on the inner periphery of the tray cover 40. The contact rib 43 protrudes from both ends on the inner periphery of the tray cover 40. A height to which the contact rib 43 protrudes may be determined in a range that rotation of the ice tray 30 does not interfere with the contact rib 43.
Meanwhile, the tray cover 40 is installed to rotate in relative to the ice tray 30. For this purpose, one of the long sides of the tray cover 40 is rotatably connected to one of the long sides of the ice tray 30 by a rotation member 45 (refer to
Also, the control housing 50 is provided to the outer surface of one of the short sides of the support frame 20. Various parts including a motor (not shown) for rotating the ice tray 30 are provided inside the control housing 50. That is, the ice tray 30 is rotated by driving force delivered from the motor.
The operation of an ice maker according to an embodiment is described below in more detail with reference to the accompanying drawings.

When the ice tray 30 continues to rotate counterclockwise, one side of the ice tray 30 is closely attached on the hooking threshold, and thus the ice tray 30 is twisted, ice I made from the ice cubes 31 is separated from the ice cubes 31. The separated ice I falls down due to its own weight and is stored in the ice bank 60 (refer to
Meanwhile, the ice I is stored in the ice bank 60, a user can take out the ice bank 60 through the home bar 6 (refer to
An ice maker and a refrigerator including the same according to another embodiment will be described in more detail with reference to the accompanying drawings.
