In general, a refrigerator is provided with a freezer compartment and a refrigerating chamber into which cold air heat exchanged by an evaporator is introduced, and a refrigerator compartment keeps food fresh at a temperature of about 3 ° C-5 ° C, and the freezer is at a temperature below zero. Keep your back frozen for a long time.

The lower part of the rear surface of the freezer compartment or the refrigerating compartment of the refrigerator is provided with a machine room provided with a compressor and a condenser for forming a refrigeration cycle.

The compressor continuously compresses the refrigerant in the gaseous state, and the pressurized refrigerant undergoes a phase change to a liquid state through the condenser. The compression and condensation of the refrigerant is an exothermic process. In order to air-cool the inside of the machine room through heat exchange, a machine room cover having a ventilation hole is installed.

However, since the refrigerator is used in a fixed state without moving for a long time in the installed state, and the machine room cover is installed at the rear of the refrigerator, dust gradually accumulates in the machine room cover as the use time elapses, and thus the accumulated dust is the opening ratio of the ventilation hole. Will drop.

Therefore, as the ventilation hole is gradually blocked, the ventilation is not made smoothly, and thus the temperature inside the machine room is increased. As a result, the cooling efficiency of the condenser is lowered, thereby lowering the cooling performance and efficiency of the entire refrigerator.

The present invention is to solve this problem, it is an object of the present invention to provide a refrigerator capable of cleaning the dust accumulated in the machine room cover without moving the refrigerator to maintain the cooling efficiency of the machine room.

In order to achieve the above object, the refrigerator according to the present invention,

Hereinafter, with reference to the accompanying drawings, an embodiment of the present invention will be described in detail.

1 is a front view showing the front of the refrigerator according to the present invention, Figure 2 is a cross-sectional view showing the internal structure of the refrigerator, Figure 3 is an exploded perspective view showing a dust discharge pipe and the machine room cover.

The refrigerator 10 according to the illustrated embodiment is provided in a double door type in which the freezing compartment door 21 and the refrigerating compartment door 31 are rotatably installed on both front sides thereof.

The inner space of the main body is partitioned into a freezing compartment 20 and a refrigerating compartment 30 by a partition wall, and a machine chamber 40 is provided at the lower rear side of the main body.

In the machine room 40, a compressor 41 and a condenser 43 are installed to perform a refrigeration cycle in order to maintain the temperatures of the freezing compartment 20 and the refrigerating compartment 30 through a cooling action.

The compressor 41 is a device for continuously compressing the vaporized refrigerant through an evaporator (not shown), and the condenser 43 is a device for liquefying the refrigerant at a high temperature and high pressure pressurized by the compressor 41.

Therefore, the condenser 43 generates condensation heat according to the phase change of the refrigerant, which is cooled by the air circulation by the cooling fan 42 installed inside the machine room 40. To this end, a machine room cover 50 having a primary ventilation hole 50a communicating with the inside and outside of the machine room 40 is provided at the rear of the machine room 40.

On the other hand, one side of the refrigerator 10 is provided with a dust discharge pipe 60 penetrating the main body in the front and rear direction. The dust discharge pipe 60 has a connection port 61 formed at one end thereof so as to be connectable with a suction pipe (not shown) of the vacuum cleaner.

The connection port 61 is installed on the front of the refrigerator 10 to be connected to the suction tube of the vacuum cleaner even when the refrigerator 10 is built in a built-in manner and is not exposed to the side, and the dust discharge pipe 60 is usually used. It is closed by the connection port cover 63 to prevent foreign matter from entering.

The dust discharge pipe 60 is provided in a structure that communicates between the connection port 61 and the machine room 40, the other end in the opposite direction to the connection port 61 is disposed in the machine room 40 and the machine room cover 63 The dust suction device is connected to remove dust.

Therefore, when the vacuum cleaner is operated while the suction pipe of the vacuum cleaner is connected to the connection port 61, the suction force generated in the vacuum cleaner is first transmitted to the suction device along the dust discharge pipe 60 to cover the machine room 50. ), You can clean the dust.

The dust suction device includes a suction guide part 62 disposed to be spaced apart from the machine room cover 50 and a suction guide part 62 so as to support the machine room cover 50 and the suction guide part 62 to be spaced apart from each other. It includes a support portion 62b that is bent to the outside of the.

As the suction guide part 62 and the machine room cover 50 are spaced apart, the space between the machine room cover 50 and the suction guide part 62 is formed as a suction flow path 51 in which suction force by a vacuum cleaner acts. The distance between the suction guide part 62 and the machine room cover 50 is formed to about 2 to 10mm so that the suction force is fully applied.

The machine room cover 50 and the suction guide part 62 communicate with the outside of the refrigerator 10 and the machine room 40 so that the machine room 40 can be cooled, and the primary vent hole 50a and the secondary vent hole 62a. Are formed respectively.

The primary through-hole 50a and the secondary through-hole 62a may be formed in plural, and their shapes and sizes may be the same or different.

However, the suction force of the dust discharge pipe 60 and the suction flow path 51 is reduced by the primary vent hole 50a and the secondary vent hole 62a, and the suction flow path close to the dust discharge pipe 60 ( In 51), the suction force is maintained at a predetermined level or more, so that dust may be sucked. However, the distance from the dust discharge pipe 60 decreases, so that the suction force of the suction passage 51 decreases.

Therefore, when the cross-sectional area of the flow path opened per unit area in the machine room cover 50 and / or the suction guide portion 62 is defined as the opening ratio, the opening ratio is changed according to the distance from the dust discharge pipe 60, so that the dust discharge pipe The farther the distance from (60) is, the smaller the opening ratio is than the portion close to the distance, so that the suction force of a certain level or more can be maintained even in the dust discharge pipe (60) and the suction flow path (51) in the far side.

The aperture ratio is varied according to the size and number of the primary and secondary vent holes 62a and 62a so as to increase the size of the vent holes 50a and 62a or increase the number thereof. Can be done.

According to the illustrated embodiment, the primary vent hole (50a) and the secondary vent hole (62a) is a line close to the distance according to the distance to the dust discharge pipe (60) of the vent holes (50a, 62a) The opening ratio is adjusted by increasing the number and decreasing the number with distance.

The primary vent hole (50a) and the secondary vent hole (62a) may be arranged side by side in the front-rear direction so that the ventilation of the machine room 40 can be made smoothly to reduce the noise transmitted to the outside from the machine room (40) May be staggered to each other.

On the other hand, the connection port 61 for connecting to the vacuum cleaner in the dust discharge pipe 60 may include an adapter to be connected to various types of vacuum cleaner.

Figure 4 shows an embodiment for such an adapter, the adapter 61a may be provided in a form having a variety of inner diameter so that the various suction pipes can be connected as shown in FIG.

In addition, as shown in FIG. 4B, the adapter 61b may be formed in a tapered form in a direction in which the diameter decreases toward the end, and may be connected to the suction tube by press-fitting the outer diameter portion of the adapter 61b.

Next, a brief look at the process of cleaning the machine room cover in the refrigerator according to the present invention.

In order to clean the machine room cover 50, the connection port cover 63 installed at the lower front of the refrigerator 10 is opened, and the suction pipe of the cleaner is connected to the connection port 61.

When the cleaner is operated by operating a switch of the cleaner, a negative pressure is formed inside the cleaner, and the suction force generated at this time is transmitted to the suction flow path 51 through the suction pipe and the first discharge pipe 60 connected thereto.

Therefore, the suction of air is made through the primary vent hole 50a and the secondary vent hole 62a, and at this time, the dust trapped in the vent holes 50a and 62a is sucked into the vent holes 50a and 62a. This can be cleaned so that the aperture ratio can be recovered.

As described above, the refrigerator according to the present invention can be easily removed using a vacuum cleaner while dust is easily caught in the machine room cover that is difficult to clean.

Therefore, even if the opening ratio of the machine room cover is reduced by the dust stuck to the machine room cover due to long-term use, and the power consumption rate is increased due to the poor cooling of the condenser, the machine room cover can be easily cleaned by the above-described method, so that the cooling performance can be restored. It can be effective.
