Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator with an automatic ice making device in which an ice tray is removable.

[0002]

2. Description of the Related Art Heretofore, as a refrigerator with an automatic ice making device of this type, there is one disclosed in, for example, Japanese Utility Model Publication No. 57-9661.

In FIG. 6, reference numeral 31 is a refrigerator main body, 32 is a freezing room formed therein, and 33 is an automatic ice making device.
The ice blocks made by this device 33 are stored in an ice storage box (not shown). The automatic ice making device 33 is composed of an ice tray 34, a drive device 35 for driving the ice tray 34, a frame 36 for associating the ice tray 34 with the drive device 35, and the like. The frame 36 is generally made of stainless steel sheet. Therefore, when the ice is removed, 40 kg cm to 60 kg transmitted from the drive device 35 to the ice tray 34 in order to release the ice from the ice tray 34.
It does not have the strength to support the force of cm. Therefore, the frame 36 is usually fixed to the partition plate 37 constituting the freezer compartment 32 by fitting the mounting hole 36a of the frame 36 to the boss 37a on the partition plate 37 side, as shown in the figure. Reference numeral 38 is a temperature sensor mounted on the back surface of the ice tray 34 for detecting ice making and water supply.

Normally, the automatic ice making device 33 receives a signal from the temperature sensor 38 to perform an ice removing operation and a water supply operation to the ice making tray 34 by operating a pump or the like (not shown).

The temperature sensor 38 is electrically connected to the drive portion 33a of the automatic ice making device 33 by a signal line 39 as shown in the figure. Since the temperature sensor 38 performs ice making detection and water supply detection as described above, the state of attachment to the ice making tray 34 is firmly fixed by a predetermined construction method at a position confirmed by a preliminary test or the like. It is fixed, and the user freely attaches it at the mounting position,
The mounting method cannot be changed.

[0006]

However, since the above-mentioned conventional refrigerator with an automatic ice making device is constructed as described above, the following problems occur when the ice making tray 34 is to be removed for replacement or cleaning. was there.

(1) Only after the main body of the automatic ice making device 33 has been removed, the ice tray 34 is placed in the drive portion 3 of the automatic ice making device 33.
It was out of reach because it was located behind 3a.

(2) A temperature sensor 38 connected to the signal line 39 is attached to the back surface of the ice tray 34 as shown in the figure, but the temperature sensor 38 is not structured so that the user can freely attach and detach it. Even if the main body of the automatic ice making device 33 is removed in the preceding paragraph, the ice tray 34 cannot be removed arbitrarily.

An object of the present invention is to improve and improve the problems which have not been taken into consideration in the above-mentioned conventional examples, and to facilitate the attachment and detachment of the ice tray.

[0010]

[Means for Solving the Problems]

(1) The first refrigerator according to the present invention has a hollow drive shaft of a drive device for imparting the ice removing operation of the automatic ice making device, has a bellows portion, and is attached to an attachment portion provided at a lower end of the ice tray. Insert an internal hollow pipe into the hollow part of the drive shaft, attach a temperature sensor for detecting ice making, etc. through the drive shaft in the pipe, and engage one of the ice trays with the drive shaft and the other of the frame. A guide groove for taking out the ice tray is provided in the bearing portion of the frame which is engaged with the bearing portion and is connected to the bearing portion, and the bearing portion of the frame is closed so that the guide groove opening is closed by the decorative cover. It is achieved by locating it on the opening (front) side of.

(2) In the second refrigerator according to the present invention, the drive shaft of the drive device for imparting the ice removing operation of the above-mentioned automatic ice making device is made hollow, and it is flexible and attached to the mounting portion provided at the lower end of the ice tray. An internal hollow pipe to be attached is inserted into the hollow portion of the drive shaft, and a temperature sensor for detecting ice making or the like is inserted through the drive shaft in the pipe, and one of the ice trays is engaged with the drive shaft and the other is A guide groove for taking out the ice tray connected to the bearing portion of the frame and connected to the bearing portion is provided in the bearing portion of the frame, and the bearing portion of the frame is closed so as to close the guide groove opening. It is achieved by positioning it on the opening (front) side of the freezer.

[0012]

According to the present invention, with the above-described structure, the ice tray can be easily removed from the automatic ice making device and cleaned or replaced without the user having to touch electrical components such as a temperature sensor for ice making detection and water supply detection. It was done. Of course, for mounting, simply engage the ice tray with the drive shaft,
As before, a temperature sensor that detects ice making and water supply can be used. In addition, by closing the guide groove opening for taking out the ice tray with the decorative cover, it is possible to prevent the shaft of the ice tray from coming off.
