Description

Refrigerator {REFRIGERATOR}

The present invention relates to a refrigerator, and more particularly, to a refrigerator having an improved structure for icing ice produced in a water supply tray and an ice tray.

A refrigerator is a device that stores a product stored therein for a long time by using a refrigeration cycle composed of a compressor, a condenser, a capillary tube (or an expansion valve), and an evaporator. The inside of the refrigerator is formed with a freezer compartment in which the article is stored at a temperature below the freezing point and a refrigerating compartment in which the article is stored at a temperature above the freezing point, which is relatively higher than the freezing compartment. The storage compartment formed inside the refrigerator is opened and closed by a door.

The refrigerator or the storage compartment of the refrigerator is equipped with an ice making housing in which an ice making room for generating ice is formed, an ice making tray accommodated in the ice making housing, and an ice storage unit for receiving ice iced from the ice making tray.

On the other hand, the ice-making housing is provided with the ice-cream part which ices ice from an ice-making tray to an ice storage part. The ice making unit applied to the conventional refrigerator uses an ice making lever to transmit a driving force to the ice making tray.

However, since the ice lever applied to the conventional refrigerator to ice the ice generated in the ice making tray is operated by the user, there is a problem that it may be damaged by prolonged use or excessive force.

In addition, since the icemaking housing is conventionally installed in the ice making housing, it occupies the storage space of the storage compartment, so that there is a problem that the storage space of the article is reduced and the usability can be reduced.

Accordingly, a main object of the present invention is to provide a refrigerator which can prevent breakage by improving a structure of icing ice generated in an ice making tray, thereby improving reliability of a product.

In addition, another object of the present invention is to provide a refrigerator having an improved structure for icing ice generated in the ice making tray to increase the storage space of the storage compartment.

And a pinion 94 provided at 20 and an interlocking gear 96 engaged between the two pinions 94. The driving means 90 is an embodiment of the present invention, and an ice making position where the ice making tray 20 is supplied with water or iced according to the sliding movement of the water supply tank 50, and an ice making position where the ice of the ice making tray 20 is iced. Allow reciprocating rotation between them.

Rack 92 is an embodiment of the present invention, is provided integrally with the water supply tank (50). The rack 92 is provided integrally with the water supply container 50 and is simultaneously reciprocated by the reciprocating movement of the water supply container 50. The rack 92 is engaged with the pinion 94 and transmits the driving force generated by the movement of the water supply tank 50 to the pinion 94.

As one embodiment of the present invention, two pinions 94 are provided corresponding to the two ice trays 20. The pinion 94 is coupled to one side rotation shaft of the ice tray 20 adjacent to the rack 92. The pinion 94 causes the ice making tray 20 to rotate between the ice making position and the ice making position in conjunction with the operation of the rack 92.

The interlocking gear 96 is provided when the plurality of ice making trays 20 are accommodated in the ice making housing 10 as in the present invention. The interlocking gear 96 is provided between the two pinions 94 to transmit the driving force to the pinion 94 that is not engaged with the rack 92 when the pinion 94 engaged with the rack 92 is driven. That is, the interlocking gear 96 allows the two pinions 94 to be rotated at the same time by the reciprocating movement of the water supply tank 50.

7A and 7B, the ice-making housing 10, the ice-making tray 20, the water supply tank 50, and the driving means 90 of the refrigerator 1 according to the present invention are constructed by such a configuration. Looking at the assembly process and operation process as follows.

First, the two ice making trays 20 are rotatably coupled to the ice making housing 10 in the horizontal direction of the rotation axis of the ice making tray 20. The pinion 94 of the driving means 90 is coupled to one rotation shaft of each ice tray 20. Then, the interlocking gear 96 is arranged between the pinions so that each pinion 94 is interlocked.

And, one side is provided with a rack 92 of the drive means engaged with the pinion 94, the other side is provided with a water supply tank 50 provided with a valve 70 for supplying water to the ice making tray 20 (10) Insert into the guide groove 16 formed in the).

On the other hand, the operation process of the ice making housing 10, the ice making tray 20, the water supply tank 50 and the drive means 90 is as follows.

The water supply container 50 mounted to the ice making housing 10 is removed from the ice making housing to supply water to the ice making tray 20. After opening the water inlet 62 by operating the water inlet stopper 64 provided in the water inlet 50, water is supplied to the water inlet 50.

The water supply tank 50 is coupled to the ice making housing 10. At this time, the valve 70 provided on one side of the water supply tank 50 and the pinion 94 provided on the other side are inserted into the guide groove 16 of the ice making housing 10.

When the water supply tank is coupled to the ice making housing 10, the discharge port 68 is opened by the contact between the valve 70 and the ice making tray 20 to supply water to the ice making tray 20 positioned at the ice making position.

When ice making is completed after a predetermined time elapses, the water container itself is moved downward. Then, the rack 92 moves with the movement of the water supply tank 50, and the pinion 94 meshed with the rack 92 interlocks. Thus, the ice making tray 20 in the ice making position is rotated to the ice making position by the rotation of the pinion 94 to ice the ice to the ice storage unit 30.

Here, when the pinion 94 engaged with the rack 92 is interlocked, the interlocking gear 96 engaged with the pinion 94 and the pinion 94 engaged with the interlocking gear 96 interlock with each other and the two ice trays 20 make ice. Rotate from position to ice position.

Thus, since the water supply and the ice in the ice tray is reciprocated by reciprocating the water supply tank for supplying water to the ice tray, it is possible to simplify the ice structure and reduce breakage and production costs.

In addition, since the ice of the ice tray is iced by the reciprocating movement of the water supply container, an additional ice removing device is unnecessary, the storage space of the storage compartment can be increased, and thus the convenience of the product can be increased.
