 2 to 5, the machine room 10 of the refrigerator 1 is installed at the rear of the lower portion of the main body 2. [

The machine room 10 is provided with a compressor 40 disposed at one side of the inside of the machine room 10 for compressing the refrigerant and a compressor 40 having a predetermined distance from the compressor 40 and having passed through the compressor 40, A condenser 50 for condensing through heat exchange and a blowing fan 60 for generating a forced flow of air spaced apart from the condenser 50 by a predetermined distance.

The compressor 40, the condenser 50 and the blowing fan 60 are arranged side by side so that outside air blown by the blowing fan 60, that is, (50). ≪ / RTI > The blowing fan 60 forcibly flows the air in the machine room 10 from the air inlet 31 side toward the air outlet 32 side.

The machine room 10 includes a back plate 20 defining a rear surface and a base plate 30 provided below the back plate 20 to form a bottom surface.

The back plate 20 may be formed in a thin plate shape in which no external air is sucked or a separate vent hole for discharging the air inside the machine room 10 is not formed. Therefore, since the rear surface of the machine room 10 is shielded by the back plate 20, it is prevented that air is sucked from the rear or the air is discharged from the rear.

The base plate 30 is provided with an air inlet 31 through which air can be sucked into the machine room 10 and an air outlet 31 through which air in the machine room 10 can be discharged to the outside of the machine room 10 32 are formed.

The air inlet 31 is provided with a suction grille 311 which divides the air inlet 31 into a plurality of spaces. The suction grille 311 may prevent foreign matter from being introduced into the air inlet 31 from the outside.

The suction grille 311 may extend in the front-rear direction or the left-right direction of the air inlet 31. In FIG. 3, the suction grille 311 extends from the front end to the rear end of the air inlet 31.

In addition, the air inlet 31 is provided with a suction guide portion 312 for guiding indoor air to the air inlet 31 side.

The suction guide part 312 may be provided on the bottom surface of the base plate 30 and may be formed by pressing the base plate 30. That is, the suction guide part 312 may be formed by cutting and bending a part of the base plate 30. [

The suction guide part 312 is provided with a first suction guide part 312a extending downwardly sloping downward at a rear end of the air suction port 31 and a second suction guide part 312b which is formed in a body with the first suction guide part 312a, And a second suction guide portion 322a extending from the end of the first suction guide portion 312a toward the charge chamber. The second suction guide portion 322a guides indoor air to the first suction guide portion 312a.

The first suction guide portion 312a is formed by bending the base plate 10 downward from the rear end of the air inlet 31. [ The first suction guide portion 312b guides the room air guided through the second suction guide portion 312b into the machine room 10. [

An angle between the second suction guide part 312b and the base plate 30 is smaller than an angle formed by the first suction guide part 312a and the base plate 30. [ This is to allow the room air in front of the air inlet 31 to be efficiently sucked.

The vertical distance from the bottom surface of the base plate 30 to the end of the second suction guide part 312b is smaller than the height of the support part 5. This is to prevent the suction guide part 312 from being deformed by making the suction guide part 312 spaced apart from the installation surface on which the refrigerator 1 is mounted.

On the other hand, the air outlet 32 is formed on the opposite side of the base plate 30 where the air inlet 31 is formed.

The air discharge port 32 is provided with a discharge grill 321 for partitioning the air discharge port 32 into a plurality of spaces as in the air suction port 31. The discharge grill 321 is the same as the suction grill 311 in terms of shape, structure, and function except that the discharge grill 321 is provided in the air discharge port 32. Therefore, a detailed description thereof will be omitted.

The air discharge port 32 is provided with a discharge guide portion 322 for guiding the air discharged to the air discharge port 32 toward the front of the machine room 10 in the same manner as the air suction port 31.

The discharge guide portion 322 may be formed on the bottom surface of the base plate 30 in the same manner as the suction guide portion 312 and may be formed by pressing the base plate 30.

The discharge guide portion 312 includes a first discharge guide portion 322a extending downward from the rear end of the air discharge port 32 and forming a downward inclination forward, And a second discharge guide part 322b extending from the end of the first discharge guide part 322a to the charge chamber.

The first ejection guide portion 322a is formed by bending the base plate 10 downward from the rear end of the air ejection 32. The first discharge guide portion 322a guides air in the machine room 10 to the second discharge guide portion 322b.

The second discharge guide portion 322b guides the air guided from the air discharge port 32 to the charge chamber by the first discharge guide portion 322a. The angle formed between the second discharge guide portion 322b and the base plate 30 is smaller than an angle formed by the first discharge guide portion 312a and the base plate 30. [ This is to allow the air discharged from the air discharge port 32 to be efficiently discharged forward.

The vertical distance from the bottom surface of the base plate 30 to the end of the second discharge guide portion 322b is formed to be smaller than the height of the support portion 5 as in the suction guide portion 312.

A partition wall (33) is formed on the bottom surface of the base plate (30) to block mixing of indoor air sucked and air discharged from the machine room (10). The partition wall 33 extends downward from the bottom surface of the base plate 30. The partition wall 33 is installed between the air inlet 31 and the air outlet 32.

The barrier ribs 33 may be formed of a soft material capable of bending. For example, the partition 33 may be made of a material including at least one of rubber and silicon. This is because the partition wall 33 is brought into close contact with the mounting surface of the refrigerator 1 by elastic deformation to maximize the effect of preventing mixing of the intake air and the discharge air.

On the other hand, the base plate 30 is provided with a seat portion 35 on which the compressor 40 can be seated. The seating part 35 may be formed in a stepped shape so that a space that can be seated can be defined.

The base plate 30 may be provided with a defrost water storage unit 35 formed below the condenser 50 and capable of dropping and storing the defrost water moved through a defrost water pipe (not shown) . The defrost water storage portion 35 may be formed by recessing at least a portion of the base plate 30 so that the defrost water can be stored in the defrost water storage portion 35.

Hereinafter, the operation of introducing and discharging the indoor air into the machine room of the refrigerator according to the first embodiment will be described in detail.

When the air blowing fan 60 operates, air flows from the air inlet 31 toward the air outlet 32.

The indoor air is reduced in air pressure at the air inlet port 31 by the air flow inside the machine room 10 and the indoor air is guided by the suction guide section 312 to be introduced into the inside of the air inlet port 31 . Since the suction guide part 312 is inclined forwardly, the air located in front of the air suction port 31 is sucked through the air suction port 31.

The air sucked through the air intake port 31 is heat exchanged with the compressor 50 and the condenser 40 while flowing through the machine room 10 by the blowing fan 60. Therefore, the temperature of the air rises more than when the air is sucked through the air inlet 31.

The heat exchanged air flows toward the air discharge port 32 side by the blowing fan 60. The pressure in the air discharge port 32 increases and the air inside the machine chamber 10 is discharged to the outside of the machine room 10 by the discharge guide portion 322. Since the discharge guide portion 322 is inclined downward forward, the air discharged from the air discharge port 32 is discharged forward. Air is discharged through the air discharge port 32, and the waste heat inside the machine room 10 is discharged to the outside air.

According to the proposed embodiment, since the air is sucked from the front of the refrigerator 1 and the air is discharged in the forward direction to make waste heat of the machine room 10 regardless of whether the refrigerator 1 is closely attached to the rear wall .

Hereinafter, a second embodiment of the present invention will be described.

FIG. 6 is a perspective view of a refrigerator according to a second embodiment of the present invention, FIG. 7 is a perspective view showing the interior of a machine room of a refrigerator according to a second embodiment of the present invention, and FIG. 9 is a cross-sectional view of the machine room of the refrigerator according to the second embodiment of the present invention, FIG. 9 is a cross-sectional view of the refrigerator according to the second embodiment of the present invention, FIG.

The present embodiment is the same as the first embodiment in the other parts, but there is a difference in the formation position of the air inlet. Therefore, only characteristic portions of the present embodiment will be described below, and the same contents as those of the first embodiment will be used herein.

6 to 11, a suction plate 150 having an air inlet 151 for sucking indoor air is formed at a lower end of a front surface of a main body 101 of a refrigerator 100 according to a second embodiment of the present invention. Respectively. Although the air intake port 151 is formed in the suction plate 150 in the present embodiment, the air intake port 151 is formed at any position on the front surface of the main body 101 .

A machine room 110 in which a compressor 120, a condenser 130 and a blowing fan 140 are accommodated is formed below the main body 101.

The machine room 110 is defined by a base plate 160 forming a bottom surface and a back plate 170 forming a rear surface.

The base plate 160 is formed with an air outlet 113 through which air in the machine room 110 can be discharged. A discharge guide part 115 for guiding the air discharged from the air discharge port 113 forward is provided on the bottom surface of the base plate 160. The discharge guide portion 115 can be inclined downward and bent at a predetermined angle. Accordingly, the air discharged from the air discharge part 113 can be effectively discharged forward.

The back plate 170 is not provided with holes through which air can be sucked and discharged, as in the case of the first embodiment.

The machine room 110 is provided with a first flow path 111 through which the air sucked from the air intake port 151 flows backward and a second flow path 111 through which the air flowing in the first flow path 111 flows The second flow path 112 is formed. For example, in the present embodiment, the first flow path 111 and the second flow path 112 are formed at right angles.

The condenser 130 may be installed in the first flow path 111.

The condenser 130 is formed in a flat hexahedral shape and can be placed on the base plate 160. Accordingly, there is an advantage that the space occupied by the condenser 130 in the machine room 110 is reduced. The air sucked into the air inlet 151 passes through the condenser 130 and performs heat exchange.

The width of the air inlet 151 may be greater than the width of the air inlet 151. The width and width of the condenser 130 may be at least the width and width of the air inlet 151, May be formed in corresponding sizes.

The air blowing fan 140 may be installed between the condenser 130 and the compressor 120 to forcibly blow air passing through the condenser 130 to the second flow path 112. The compressor 120 may be installed in the second flow path 112.

A plurality of the compressors 120 may be installed. For example, in this embodiment, two compressors 120 are installed. This is because the condenser 130 is formed in a flat shape and the volume occupied inside the machine room 110 is small.

Hereinafter, how the room air flows in and out of the machine room of the refrigerator according to the second embodiment will be described in detail.

First, when the blowing fan 140 operates, indoor air is sucked through the air inlet 151. The air inlet 151 is formed at a front side of the main body 101 so that the air in front of the refrigerator 101 is sucked into the air inlet 151.

The air sucked into the air intake port 151 flows through the first oil passage 111 in which the condenser 130 is installed. The air flowing through the first flow path (111) exchanges heat with the condenser (130).

The air having undergone heat exchange with the condenser 130 is forcibly turned by the blowing fan 140 and flows into the second flow path 112. Since the condenser 130 is in close contact with the bottom, the air passing through the condenser 130 can flow upward into the second flow path 112 while spreading upward. The air flowing through the second flow path (112) exchanges heat with the compressor (120).

The air having undergone the heat exchange with the compressor (120) is discharged to the air discharge port (113). The air flowing through the second flow path (112) can exchange heat with the compressor (120). The air having undergone the heat exchange with the compressor 120 is discharged to the outside air through the air outlet 113. The air discharged from the air outlet 113 is guided to be discharged to the front of the refrigerator 100 by the discharge guide portion 115.

According to the proposed embodiment, the air intake port and the air discharge port are not formed in the back plate of the machine room, and air is sucked in from the front and air is discharged in the forward direction. Thus, regardless of whether the refrigerator is closely attached to the rear wall, There is an advantage of being smooth.

In addition, the condenser is installed at the rear of the air intake port, and is formed in a shape corresponding to the shape of the air intake port, so that heat exchange of the condenser is efficiently performed.

Further, since the shape of the condenser is flat, a plurality of compressors can be installed in the machine room.
