(57) [Summary] [Purpose] To provide a structure for surely stopping the automatic ice making water supply operation when the ice tray of the automatic ice making device is removed. [Structure] The ice tray 1 is formed so as to be detachable after being pulled out from the holding frame 2 by a predetermined distance, and a stopper 5 that is movable integrally with the movement of the ice tray 1 is provided,
The detection lever 3 is configured to come into contact with the stopper 5 at the pulled-out position.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an automatic ice making device configured in an electric refrigerator or the like.

[0002]

[Prior Art]

 Conventionally, the automatic ice making device installed in the electric refrigerator for home use could not remove the ice making tray. However, the ice tray is a place where water accumulates, and there is a problem that it is unsafe if it is not always washed. In order to improve this, it is desirable to be able to remove the ice tray as needed, but since it is an automatic ice making device, the water supply operation is automatically performed regardless of this with the ice tray removed. When the start of the operation, there was a problem that the inside of the freezer became wet.

[0003]

[Problems to be solved by the device]

 The present invention has been made in view of the above-mentioned conventional drawbacks, and provides a structure for surely stopping the automatic ice making water supply operation when the ice tray of the automatic ice making device is removed.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, a holding frame for pulling out the ice tray and detachably holding the ice tray is formed in a driving device, and the holding frame is sandwiched between the holding frame and the bottom portion of the ice tray, and the ice tray attaching / detaching operation is performed. A stopper that is pulled out in conjunction with is provided, and this stopper is brought into contact with the lower surface of the detection lever at the pulled-out position to lock the detection lever.

[0005]

[Action]

 According to the above configuration, the ice tray is always held in the holding frame, and if it is taken out as needed for cleaning or the like, it cannot be removed unless it is pulled out from the holding frame by a certain distance. ing. By using this operation, a stopper that is sandwiched between the bottom of the ice tray and the holding frame to move integrally with the movement of the ice tray is provided, and when the ice tray is taken out, this stopper moves to the front side. When the stopper is pulled out, it comes into contact with the lower surface of the detection lever of the automatic ice making device and stops the detection operation of the detection lever. As a result, the automatic ice making operation thereafter is interrupted, the water supply operation is stopped, and it is possible to prevent the inside of the freezer from becoming flooded. Also, when the ice tray is returned to the holding frame, the stopper also returns and the function of the automatic ice making device is restored.

【Example】

 An embodiment of the present invention will be described with reference to the accompanying drawings. In FIG. 1, reference numeral 1 is an ice tray of an automatic ice making device, and the ice tray 1 is attached to and detached from a holding frame 2 installed in a freezer. Can be installed freely. A driving device 4 having a detection lever 3 is provided near the holding frame 2. Further, an edge portion 12 having a recess 11 is formed on a side portion of the ice tray 1, and a holding edge 21 of the holding frame 2 is formed with a notch 22 corresponding to the edge portion 12. Further, between the central bottom portion 13 of the ice tray 1 and the central bottom portion 23 of the holding frame 2, a stopper 5 having an engaging piece 51 sandwiched between the stoppers 5 is provided so as to be movable back and forth. When the stopper 5 is pulled out, the detection lever 3 comes into contact with the stopper 5. With the above configuration, the ice tray 1 is housed in the holding frame 2 as shown in FIG. 2 during the operation of the automatic ice making device. In this form, the stopper 5 is in the retracted position, and after the downward rotational movement of the detection lever 3 of the drive device 4 previously programmed, the ice storage level of the ice stocker under the ice making device is detected. Then, the operation goes to the next ice making operation, and the water supply device is activated to supply water into the ice tray 1. After that, when ice making is performed and the inside of the ice tray 1 is frozen, the shaft 24 of the holding frame 2 is driven by the driving device 4 and the ice tray 1 is turned upside down integrally with this, and the ice inside is put in the stocker. Dropped. Next, when the ice tray 1 is pulled out in the forward direction along the holding edge 21 of the holding frame 2 for cleaning, it can be pulled up and taken out when the edge portion 12 is located in the notch 22. The engaging piece 51 is pulled out integrally with the movement of the ice tray 1, and the stopper 5 is sent to the front side. When the detection lever 3 of the drive unit 4 rotates at the position where the stopper 5 is pulled out, the movement is stopped by hitting the stopper 5, and the ice tray 1 is removed as in the case where the stocker is filled with ice. The removal is detected. As a result, the ice making operation thereafter is interrupted, the water supply operation is stopped, and it is possible to prevent the inside of the freezer from becoming flooded. Further, when the ice tray 1 is returned into the holding frame 2, the stopper 5 also returns, and the function of the automatic ice making device is restored.

[0007]

[Effect of the device]

 As described above, according to the automatic ice making device of the present invention, when the ice tray is cleaned, the ice tray cannot be removed unless it is pulled out from the holding frame by a certain distance. By providing a stopper that moves integrally with the movement of the ice tray, when the ice tray is taken out, the stopper is pulled out to the front side, and the detection lever is brought into contact with the pulled out stopper to detect the detection lever. To stop. As a result, the water supply operation thereafter is stopped, and it is possible to prevent the inside of the freezer from becoming flooded.
