Description

REFRIGERATOR AND DRAWER GUIDE ASSEMBLY THEREOF < RTI ID = 0.0 >

The present invention relates to a drawer guide assembly for a refrigerator and a refrigerator.

A refrigerator is a device intended for low-temperature storage of food. Depending on the type of food to be stored, the refrigerator can be frozen or refrigerated.

The interior of the refrigerator is cooled by the continuously supplied cold air, and the cold air is continuously generated by the heat exchange action of the refrigerant by the refrigeration cycle through compression-condensation-expansion-evaporation process. The cold air supplied to the inside of the refrigerator is uniformly transferred to the inside of the refrigerator by the convection so that the food inside the refrigerator can be stored at a desired temperature.

The main body of the refrigerator is in the form of a rectangular parallelepiped having an opened front face, and a refrigerator compartment and a freezer compartment can be provided inside the body. In addition, a refrigerator compartment door and a freezer compartment door for selectively shielding openings may be provided on the front surface of the main body, and a plurality of drawers, a shelf, and a vegetable compartment for storing various foods in an optimal state may be provided in a storage space inside the refrigerator. .

However, in the case of the conventional refrigerator, the drawer is provided in the refrigerator by the sliding rail device so as to be able to enter and exit the refrigerator. When the refrigerator is used for a long time, the refrigerator may become dirty by food stored in the drawer, Lt; / RTI >

At this time, the drawer has to be detached from the sliding rail device to be cleaned or repaired. However, in the conventional refrigerator, it is not easy to detach the drawer from the sliding rail device.

1 to 5, a refrigerator according to an embodiment of the present invention has a structure in which rails can be easily assembled to a drawer 60 in an up-down manner, and the rails can be easily assembled or disassembled into a drawer 60 .

The refrigerator to be applied to the present embodiment is a bottom freeze type refrigerator in which the freezing chamber 11 is located at a lower portion. However, the present invention is not limited thereto and the present invention can be applied to various types of refrigerators.

The refrigerator includes a refrigerator body 10 forming an outer shape of a refrigerator, a door (not shown) for opening and closing an inner space of the refrigerator body 10, a cold air generating unit 30 generating cold air, And a drawer guide assembly 100 for allowing the refrigerator body 10 to enter and exit the refrigerator body 10.

Specifically, the refrigerator body 10 is a housing constituting the outer shape of the refrigerator, and can be partitioned into a freezing chamber 11 and a refrigerating chamber 12 by a barrier. For example, a freezing chamber 11 provided with a drawer guide assembly 100 may be provided below the refrigerator body 10, and a refrigerating chamber 12 may be provided above the refrigerator body 10. The freezing chamber (11) and the refrigerating chamber (12) can be opened or closed by a door.

The door may comprise a refrigerator door and a freezer door. The freezing compartment door can seal the freezing compartment 11 by sealing the lower front edge of the refrigerator body 10 and the refrigerator compartment door can seal the refrigerating compartment 12 by sealing the upper front edge of the refrigerator body 10.

The cool air generating unit 30 can generate cool air for cooling the freezing chamber 11 and the refrigerating chamber 12. [ For this purpose, the cold generator 30 may be composed of refrigeration cycle devices for generating cold air. For example, the cold air generating unit 30 may include a compressor, a condenser, an expansion valve, and an evaporator that form a refrigeration cycle. In these compressors, condensers, expansion valves, and evaporation coils, the refrigerant is heat-exchanged by the refrigeration cycle through the process of compression-condensation-expansion-evaporation, so that the air in the refrigerator can be cooled by the cooling air have.

The drawer guide assembly 100 includes a first rail 110 assembled to the side engaging jaws 61 of the drawer 60 and a second rail 110 installed on the side wall of the refrigerator body 10 to guide the movement of the first rail 110 And may include a second rail 120. Since the side catching jaws 61 of the drawer 60 are provided in the form of grooves that are recessed below both side portions of the drawer 60, the load of the drawer 60 is transmitted to the refrigerator body 10 To the second rail (120) of the vehicle.

The first rail 110 of the drawer guide assembly 100 may be formed as a vertical rail having a moving rail structure extending in the front and rear direction of the refrigerator and being supported by the second rail 120. The first rail 110 can slide along the second rail 120 and guide the drawer 60 in a forward and backward direction of the refrigerator.

In particular, the first rail 110 can be simply assembled or disassembled in the drawer 60 in an up-down fashion. For example, when the first rail 110 is assembled to the drawer 60, the rear end of the first rail 110 is inserted into the rear end of the drawer 60, It is possible to fix the front end to the leading end of the drawer 60. [ When the first rail 110 is separated from the drawer 60, the screw is released to separate the front end of the first rail 110 from the front end of the drawer 60, and then the rear end of the first rail 110 At the rear end of the drawer (60).

Here, an engaging member 111 may be provided at the rear end of the first rail 110 to be fitted into the rear end of the drawer 60 (for example, the engaging hole 62). The engaging member 111 includes a supporting hook 111a protruding vertically from one end of the first rail 110 and a locking hook 111a extending horizontally from the supporting hook 111a to be fixed to one end of the drawer 60. [ (111b).

When the engaging hook 111b of the engaging member 111 is engaged with the engaging hole 62 of the drawer 60, the tip of the first rail 110 is screwed into the screw hole of the drawer 60 The first rail 110 can be quickly and conveniently assembled to the drawer 60 by means of a simple assembly method in which the first rail 110 is fixed to the drawer 60. [ At this time, if the first rail 110 is assembled in the reverse order, the first rail 110 can be quickly and conveniently separated from the drawer 60.

The second rail 120 may be fixed to the side wall of the refrigerator body 10 via the supporter 130, and may have a support rail structure extending in the front-rear direction of the refrigerator. To this end, the second rail 120 includes a guide rail 122 having a vertical section of a "U" shape and fixedly mounted on the upper portion of the supporter 130, a guide rail 122 fixed to the lower portion of the supporter 130 through a screw, And a support bracket 123 for supporting a lower portion of the support bracket 122.

At this time, the other side of the guide rail 122 may be fixed to the upper portion of the supporter through a plurality of screws so that one side of the guide rail 122 supports the first rail 110.

Since the first rail 110 slides on the second rail 120, the inner wall of the first rail 110 (for example, the first rail 110) The upper inner wall, the one inner wall, and the other inner wall) can be contacted and supported in three directions.

As described above, the present invention allows the rails to be easily assembled or disassembled into a drawer without the aid of a specialist, the drawers can be easily opened and closed, the rails can be easily opened and closed, So that a stable and uniform distribution load of the drawer can be realized when the drawer is opened and closed in the refrigerator.

It is to be understood that the embodiments described above are merely illustrative of some examples of the technical idea and the scope of the technical idea is not limited to the described embodiments, It will be understood that various changes, substitutions, and alterations may be made therein without departing from the spirit and scope of the invention.
