The present invention relates to a machine room cover of a refrigerator, and more particularly, a first door and a second door configured to be slidable from both sides to the front of the machine room of the refrigerator to reduce heat dissipation and noise of the refrigerator. It relates to a machine room cover of a refrigerator that can open the machine room completely in case of component failure.

In general, a refrigerator is used to freeze or refrigerate food and the like, and a case for forming a storage space separated into a freezer compartment and a refrigerating compartment, and a top and bottom of the case, which are mounted at one side of the case to open and close the freezer compartment and the refrigerator compartment. It comprises a lower door, a device for lowering the temperature of the freezer compartment and the refrigerating compartment by forming a refrigeration cycle such as a compressor, a condenser and an evaporator.

In such a refrigerator, a low-temperature and low-pressure gaseous refrigerant is compressed to a high temperature and a high pressure, and the compressed high-temperature and high-pressure gaseous refrigerant is cooled and condensed as it passes through a condenser to be converted into a high-pressure liquid state. Once the refrigerant passes through the capillary tube, its temperature and pressure are lowered, and then the evaporator continues to change into a low-temperature and low-pressure gas state, taking heat from the surroundings to cool the air around it. Air cooled through the evaporator is introduced into the freezer compartment and the refrigerating compartment by the operation of a blower fan, thereby lowering the temperature of the freezer compartment and the refrigerating compartment.

On the other hand, the machine room is formed in the lower rear part of the refrigerator main body. The main parts of the machine room, except for the evaporator, are installed among the parts constituting the refrigeration cycle of the refrigerator, and the machine room will be described in detail with reference to the drawings.

FIG. 1A schematically illustrates a machine room structure of a conventional refrigerator. As shown in FIG. 1A, a compressor 11 for compressing a refrigerant into a high pressure liquid state is installed at one side of the machine room 10. One side of the compressor 11 is provided with a condenser 12 for dissipating heat of a relatively high temperature refrigerant by heat exchange in an evaporator (not shown).

And the fan guide 13 is installed on one side of the condenser 12. The fan guide 13 is to prevent the backflow of the air flow formed by the rotation of the blowing fan 14, as will be described later, the through-hole through which the blowing fan 14 is installed in the central portion of the fan guide 13 13a is formed.

Meanwhile, the compressor 11 and the condenser 12 emit heat during the operation. That is, the compressor 11 generates heat in the process of compressing the refrigerant, and heat is released in the process of radiating heat of the refrigerant in the condenser 12. Therefore, in order to discharge heat generated in the components installed in the machine room 10 to the outside, the above-described blower fan 14 is installed on one side of the machine room 10.

The blower fan 14 is disposed on the through hole 13a of the fan guide 13, and an outlet portion for discharging air is disposed to face the condenser 12, and a fan motor having a rotating shaft disposed at one side thereof ( 15). Accordingly, the blower fan 14 sucks air to the outside by driving the fan motor 15 and discharges the air toward the compressor 11 and the condenser 12 located in front of the airflow for the heat dissipation of the machine room 10. Will form.

1B is a view showing a machine room cover of a conventional refrigerator, as shown, the machine room of the refrigerator is kept closed by the cover 20. The cover 20 is formed with a plurality of heat dissipation holes 20a.

The heat radiating hole 20a radiates heat generated from the compressor 11, the condenser 12, and the like installed inside the machine room to the outside of the refrigerator. By dissipating the heat of the compressor 11 and the condenser 12 in this way, the driving efficiency of the compressor and the condenser is improved, and the driving efficiency of the refrigerating cycle can be sufficiently secured.

At the same time, the heat dissipation hole 20a serves to reduce noise generated inside the machine room.

However, in general, since the heat or noise generated in the machine room of the refrigerator is changed according to the surrounding environment such as time and temperature, the structure in which the heat dissipation hole is simply formed in the machine room cover integrally formed in the main body as described above is effectively used in the machine room. It was not possible to release the heat generated or effectively reduce the excessive noise generated in the machine room.

The present invention has been made to solve the above problems, an object of the present invention is to provide a machine room cover of the refrigerator that the user can directly open and close the machine room to heat radiation or reduce noise generated in the machine room.

In addition, an object of the present invention is to provide a machine room cover of a refrigerator that can completely open the machine room in order to facilitate replacement and repair of parts in case of failure of the parts provided in the machine room.

According to an aspect of the present invention for achieving the above object, as a cover for heat dissipation and noise reduction of the machine room provided in the rear lower end of the refrigerator, mounted on the refrigerator main body in the front of the machine room, and arranged in the longitudinal direction on the upper and lower sides, respectively A frame to which the first and second guide rails are mounted; And first and second doors that slide on the first and second guide rails of the frame to open and close the machine room.

In addition, the frame is formed on the left and right sides so that the grooves having the same size as the longitudinal length and width of the first and second doors can be separated from the left and right sides of the frame. .

In addition, the first and second doors are characterized in that a plurality of heat radiation holes are formed.

In addition, the first and the second door is characterized in that the handle portion is formed in a position adjacent to the side of the frame, respectively.

In addition, the handle is characterized in that formed by perforating the first and second doors.

Therefore, by opening and closing the first door or the second door provided in the machine room there is an effect that the user can adjust the noise or heat generated in the machine room to the desired level.

In addition, when the failure of the parts provided in the machine room, the first door and the second door is completely opened, thereby making it easy to replace and repair parts.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the machine room cover of the refrigerator according to the present invention.

2 is a front perspective view showing a machine room cover of a refrigerator according to the present invention. As shown in the drawing, a square frame 110 is mounted on a front surface of a machine room 100 located at a lower rear side of the refrigerator, and the frame ( A sliding first door 120 and a second door 130 are mounted inside the 110.

The frame 110 is fastened to the refrigerator main body 200 by fastening means 140 such as pins or bolts at each corner, and is provided on the general sliding doors at the upper and lower sides of the frame 110 to open and close the doors.
