Description

Refrigerator {Refrigerator}

The present invention relates to a refrigerator, and more particularly, to a refrigerator including a link member installed inside a storage compartment and allowing a container placed inside the storage compartment to enter and exit from the outside.

Generally, a refrigerator is a kind of home appliance for cooling and storing food stored in a storage compartment by using a cooling cycle including a compressor, a condenser, an evaporator, and an expansion valve. The refrigerator is provided with a door on one side thereof to allow food to enter and exit the refrigerator. However, when withdrawing heavy foods contained in a storage room such as a kimchi refrigerator to the outside, there is a problem that the user's body can be crowded as well as a great strength for a user whose strength is relatively weak, such as a housewife.

Therefore, in recent years, as disclosed in Korean Utility Model Registration No. 0311796, a shelf that is lifted by a motor is installed inside the storage compartment so that the user can easily take out food and shelves to the outside of the storage compartment without applying any force. As shown in FIG. 1, the refrigerator 110 according to the related art has a shelf 110 in which a kimchi container (not shown) is seated in the storage space 120, and a driving motor 300 at a lower end of the shelf 110. Was fixed. When power is applied to the driving motor 300, the worm gear 410, the first bevel gear 420, and the second bevel gear 410 mesh with the driving gear 310 and the driving gear 310 to change the rotation direction of the driving gear. 510, the rope winding machine 500 is rotated together. When the rope winding machine 500 is rotated, one end is wound around the rope winding machine 500 and the other end is lifted by the shelf 110 by the rope 600 installed at the upper portion of the storage space 120. In addition, the guide roller 710 moves up and down along the guide groove 210 formed on the side wall of the storage space 120 so that the shelf 110 is not shaken left and right when the shelf 110 is lifted by the rope 600.

However, such a refrigerator has a problem that the driving motor 300 and the power transmission unit are not smoothly driven in the storage space 120 having a low temperature because the driving motor 300 is installed in the storage space 120.

In addition, since the drive motor 300 is installed below the shelf 110, the drive motor 300 itself acts as a load together with the shelf 110 and the kimchi barrel, thereby causing unnecessary power consumption.

In addition, since the temperature inside the storage space 120 is increased by the heat generated as the driving motor 300 is driven, there is a problem that the cooling efficiency may be lowered.
