Description

Refrigerator with sliding shelf {REFRIGERATOR WITH SLIDING SHELF}

The present invention relates to a refrigerator having a sliding shelf, and more particularly, to a refrigerator having a sliding shelf to facilitate a sliding operation during withdrawal and storage.

As is well known, a refrigerator is a device for refrigeration or freezing food to be kept fresh, and includes a refrigerator body having a cooling chamber therein and a refrigeration cycle (apparatus) for providing cold air to the cooling chamber.

The refrigeration cycle is usually a vapor compression refrigeration cycle having a compressor for compressing a refrigerant, a condenser condensed while the refrigerant radiates heat, an expansion device for depressurizing and expanding the refrigerant, and an evaporator in which the refrigerant absorbs latent heat of the surroundings and evaporates. It is composed.

1 is a perspective view of a conventional refrigerator, and FIG. 2 is a cross-sectional view of the shelf mounting area of FIG. 1. As shown in FIG. 1, the refrigerator includes a refrigerator main body 10 having a freezing compartment 20 and a refrigerating compartment 40 formed therein, and a freezing chamber door that opens and closes the freezing compartment 20 and the refrigerating compartment 40, respectively. 25) and a refrigerating chamber door (45).

Inside the freezing compartment 20 and the refrigerating compartment 40 are provided with a plurality of shelves (27, 47) are arranged horizontally to partition the inner space up and down to accommodate and support the food on the upper surface. Shelf support units 30 and 50 are formed in the freezer compartment 20 and the refrigerating compartment 40 to support the shelves 27 and 47, respectively.

On the other hand, the refrigerator main body 10, the outer case (outer case) (12a) forming the appearance and the spaced apart spaced apart spaced interval of the heat insulating material (12c) inside the outer case (12a) is substantially freezer compartment ( 20) and an inner case 12b forming the refrigerating chamber 40.

Looking specifically at the shelf support 50 of the refrigerating compartment 40, the shelf support 50 is formed integrally on the inner wall of the refrigerator main body 10, as shown in FIG.

The shelf support part 50 includes an upper support part 51a and a lower support part 51b which respectively protrude inwards from the inner case 12b so as to receive one end of the shelf 47 and support the upper end and the lower end, respectively. A slot 51c is formed between the upper support part 51a and the lower support part 51b. Each shelf support unit 50 may be formed to be spaced apart at predetermined intervals along the up and down directions to adjust the position of the shelf according to the height of food or storage stored in the upper surface of the shelf 47.

However, in the conventional refrigerator, the shelf 47 and the shelf support part 50 are configured to be in surface contact, and thus there is a problem in that the sliding operation is not smoothed when the shelf 47 is taken out and stored.

In addition, the shelf 47 has a problem that the restraint occurs when the shelf 47 is inclined while the speed difference between the left and right occurs during the forward and backward sliding movement. In particular, in some refrigerators, when the cooling chamber is formed with a larger left and right width than the front and rear width, the shelf 47 is also formed with a longer left and right length than the front and rear width so as to correspond to the shape of the cooling chamber. There is a problem that restraint due to the left and right speed difference may occur more frequently when moving forward and backward directions.

Accordingly, an object of the present invention is to provide a refrigerator having a sliding shelf which can reduce the contact area of the shelf and facilitate the sliding operation.

Another object of the present invention is to provide a refrigerator provided with a sliding shelf that can suppress the occurrence of restraint of the shelf due to the speed difference when the shelf is taken out or stored.
