It is comprised by the drive device which performs.

  Conventionally, an automatic ice making device mounted on a household refrigerator has been incorporated after the heat insulating partition wall that partitions the refrigerator compartment and the freezer compartment is fixed to the refrigerator body when mounted on the refrigerator body.

  In addition, in order to simplify the configuration of the ice making device and reduce the manufacturing cost, a refrigerator is known in which a water supply tank, a water supply device, and an ice tray are integrated (see, for example, Patent Document 1).

  The conventional automatic ice making device disclosed in Patent Document 1 will be described below with reference to the drawings.

  FIG. 6 is a cross-sectional view of a main part of an ice making device used in a conventional refrigerator.

  In FIG. 6, the ice making unit 102 disposed in the freezer compartment 101 includes an ice tray 103, an ice storage box 104 for storing ice, and a water supply unit 105 for supplying water to the ice tray 103.

  The water supply unit 105 includes a water supply tank 106, a water supply valve 107, and a water supply pipe 108. The water supply tank 106 and the water supply valve 107 are disposed in a heat insulating box 109, and the water in the water supply tank 106 is not frozen. A heating element 110 is disposed, and a temperature detector 111 that controls the heating operation of the heating element 110 is provided. Moreover, the installation detector 112 which detects whether the water supply tank 106 is installed in the predetermined position is provided. A part of the heat insulating box 109 is provided with an openable / closable door 113, and further includes an open / close detector 114 for detecting the open / close state, and a driving device 115 such as a motor for driving the open / close door 113 to close. Has been placed.

  The ice making device configured as described above opens the open / close door 113 to store water in the water supply tank 106, and then opens the water supply valve 107 to supply water to the ice making tray 103 through the water supply pipe 108. The water supplied to the dish 3 is exposed to the cold air in the freezer compartment 101 and freezes to produce ice. The generated ice is deiced by rotating the ice tray 103 and falls into the ice storage box 104 below the ice tray 103 to be stored.

The unit or ice making unit can be installed, and the assembly workability of the cooling storage device can be improved.

  Moreover, since the water supply unit and the ice making unit are not arranged on the same surface, an article storage space in the storage room can be secured.

In this case, what is necessary is just to affix a heat insulating material beforehand to the protrusion part 30 of the heat insulation wall 3, and to attach the heat insulation wall 3 to the main body 41 by the same operation | work.

  Therefore, when assembling the refrigerator, the ice making device 1 can be incorporated into the main body 41 in conjunction with the incorporation of the heat insulating wall 3 into the main body 41, so that the assembling workability in the refrigerator can be greatly improved. The power supply line 21b can be easily connected to the power supply part (connectors and the like) of the main body 41 with one connection connector 21c, and furthermore, the heat insulation wall 3 and the attachment part 44 are fitted to each other so that the temperature range is different. The temperature leak (cold air leak) between the refrigerator compartment 42 and the freezer compartment 43 can also be suppressed, and the fall of the quality and reliability as a refrigerator-freezer can be suppressed.

  In addition, it is a burden on the worker when attaching the heat insulating wall 3, and the work and mounting posture of the ice making device 1 can be improved in a limited space as in the prior art. In the case of the refrigerator, the effect of improving the working posture is greatly obtained, the reliability of the work content can be increased along with the reduction of the burden of the working posture, and the refrigerator and refrigerator having improved quality and reliability of the ice making device are obtained. Is something that can be done.

Furthermore, mounting on refrigerators with different accommodation volumes can be handled only by changing the size of the heat insulating wall 3 having the same configuration, and versatility can be improved. In addition, by adding a series of control functions from the ice making detection to the ice removing operation and the ice making tray 22 returning operation to the control board 21a, the function as the ice making device 1 is not impaired.

  When a function for detecting the ice removal timing such as ice making detection is provided on the main body 41 side, the signal line connection function may be added to the connection connector 21c without any significant change.

  Even if the inner wall configuration of the refrigerator is different, the versatility can be further increased by adopting a configuration in which the peripheral wall configuration of the heat insulating wall 3 is matched to the mounting configuration provided on the refrigerator inner wall. Even if it exists, the assembly workability | operativity of the ice making apparatus 1 is not influenced.

  The automatic ice making device according to the present invention has, for example, a structure in which an ice making device is attached to a partition wall that partitions a refrigerator compartment and a freezer compartment, and the partition wall is attached to a cooling storage device such as a refrigerator. It can be widely applied from small small refrigerators to large refrigerators.
