Inlets 422 are provided. The front suction holes 421 may be formed toward the front end of the refrigerator main body 100 at the bottom of the refrigerator main body 100.

In this case, the side suction openings 422 may be formed at a width (part toward the front of the refrigerator main body 100) that forms half of the edge length of the cover body 410 in which they are located. This is to prevent the heated outside air from being introduced from the rear outer region of the refrigerator main body 100 in which the compressors 210 are located.

Accordingly, the condenser 220 is exposed to the bottom of the refrigerator main body 100 due to the inlets 420 formed in the condenser cover 400, the inlet 420 is the front of the refrigerator main body 100 In order to guide the outside air to flow into the condenser 220 side through the bottom of the refrigerator main body 100 may be formed a flow path (a).

In addition, the pair of compressors 210 may include a first compressor 211 and a second compressor 212. Here, the first compressor 211 is disposed in the machine room area 140 to be located at the bottom of the refrigeration area 110, the second compressor 212 is located in the machine room area to be located at the bottom of the refrigeration area (110).

In addition, a turbo fan 230 is installed in the machine room region 140 in which the second region ② is formed. The turbo fan 230 is disposed between the first and second compressors 211 and 212. The first and second compressors 211 and 212 are spaced apart from each other by a predetermined distance.

Here, the turbo fan 230 sucks the outside air into the first area (1) and forcibly flows to the second area (②), so that the rear cover (installed behind the machine room area 140 from the second area (②) ( It is to be discharged to the outside through the outlet 151 of 150. In this process, the suctioned outside air cools the condenser 220 in the first region ① and the outside air flowed into the second region ② cools the first compressor 211 after the turbo fan 230. Cooling the second compressor 212 can be discharged to the outside.

Here, the first and second compressors 211 and 212 in the second region ② are spaced apart from the turbo fan 230 by a predetermined distance, and are sequentially disposed at a predetermined time interval to the outside air flowing from the first region ①. As a result, the outside air flow resistance in the second region (2) can be reduced, and the compressor cooling efficiency can be increased.

In addition, a turbo fan 230 is mounted between the compressors 210 in the second region ②. Here, the turbo fan 230 may be disposed at the bottom between the refrigeration region and the refrigeration region.

Here, in the present invention, the first region ① and the second region ② are distributed to each other, the condenser 220 is located at the front side of the refrigerator main body 100, and the pair of compressors 210 is a refrigerator. It is arranged at the rear side of the main body 100. In addition, the arrangement position of the condenser 220 and the installation position of the turbo fan 230 may be different from each other.

In addition, the turbo fan 230 is a fan that does not have a shroud, and is a fan having a certain blowing ability. For example, the turbo fan 230 may use a fan having a blowing capacity of about 60% or more compared to the case where a single compressor 210 is used.

Here, when the turbo fan 230 is operated in a state located between the pair of compressors 210, outside air is sucked into the first region ① and passes through the condenser 220, and the second region ② It flows to the side) and passes through the second compressor 212 located in the turbo fan 230 side via the first compressor 211. The outside air that has passed through the second compressor 212 forms a flow path a discharged to the outside through an outlet 151 formed in the rear cover 150 installed at the rear end of the machine room region 140.

In particular, the turbo fan 230 has a blowing capacity of about 60% or more compared to the case where the compressor 210 is a single unit, the compressors 210 for compressing the refrigerant in the second area (②) is a turbo fan ( 230 is disposed in a pair spaced apart from each other by a predetermined distance to increase the amount of heat generated from them to cool them efficiently.

In addition, the first and second defrost water storage containers are provided in the second region.

The first defrost water storage container is installed between the first compressor and the second compressor, and is connected to the refrigerating area to store a predetermined amount of defrosted defrost water generated from the evaporator on the refrigerating area side. The first defrost water storage container has a drain pipe exposed to the outside of the refrigerator main body to discharge the defrost water to the outside.

In addition, the second defrosting water storage container is installed in close contact with the upper end of the second compressor, is connected to the freezing region is stored a predetermined amount of frost melted defrost water generated from the evaporator of the freezing region side. The second defrost water storage container has a drain pipe exposed to the outside of the refrigerator main body to discharge the defrost water to the outside.

Next, the operation of the refrigerator of the present invention having the above configuration will be described.

1 and 2, the refrigeration cycle apparatus 200 according to the present invention is disposed in the machine room region 140 which is partitioned from the refrigerating / freezing regions 110 and 120, and the machine room region 140 is the first region ( ①) and the second area (②). Here, the clearance between the top and bottom of the first region ① may be smaller than the clearance between the second region ②.

In the first region ①, the condenser 220 is installed in the insertion groove 310 of the insulation foam 300 formed in the lower frame 160, and thus, the volume inside the refrigerator body 100 is greater than or equal to a predetermined level. Can be increased. That is, the contents of the refrigerator may be increased by the installation area of the condenser 220. In addition, since the heat transfer area is located at the bottom of the refrigerating region 110, the heat transfer area may be increased by a predetermined value or more.

The condenser 220 may be exposed to the outside air through the inlets 420 formed in the condenser cover 400 installed in the opening 161 of the lower frame 160.

In the present invention, an outside air flow passage a connecting the first area ① and the second area ② may be formed, which is due to the operation of the turbo fan 230, and the outside air is inlet of the condenser cover 400. It may be made in such a way that the suction through the 420.

That is, when the turbo fan 230 having a predetermined or more blowing ability is operated, a predetermined suction force is generated in the first and second areas. Therefore, the outside air in front of the refrigerator main body 100 flows to the bottom of the refrigerator main body 100, and is then sucked into the condenser cover 400 through the inlets 420 of the condenser cover 400.

Here, the suction ports 420 through which the outside air is forcibly sucked are formed of the front suction ports 421 facing the front of the refrigerator main body 100 and the side suction ports 422 forming both sides of the refrigerator main body 100. In particular, since the side inlets 422 are formed at a width corresponding to half of both side edges of the condenser cover 400 (width toward the front side of the refrigerator main body 100), the compressors 210 are formed. The outside air at the rear end of the installed refrigerator can be prevented from being sucked directly.

That is, the condenser cover 400 according to the present invention has an outside air at the front side of the refrigerator main body 110 having a predetermined temperature or less than the outside air at the rear end of the refrigerator corresponding to the position where the compressors 210 that generate heat at a predetermined temperature are mounted. By guiding the suction, the condenser 220 may be exposed to the outside air introduced from the front of the refrigerator.

Accordingly, the condenser 220 that generates heat by condensing the refrigerant may be primarily cooled due to outside air suction.

As such, the outside air sucked through the inlets 420 of the condenser cover 400 cools the condenser 220 in the first region ① and flows to the second region ②.

At this time, the width of the first region ① up and down is smaller than the width of the second region ② up and down, so that the outside air flow velocity in the first region ① is increased to the second region ②. It may be increased over time during the following. When the air flows from the first region ① to the second region ②, the outside air may spread from the second region ②.

Accordingly, the outside air after cooling the condenser 220 in the first region ① spreads in the second region ② to sequentially cool the pair of compressors 211 and 212.

First, the outside air introduced into the second area ② cools the first compressor 211 located at the bottom of the refrigerating area 100, and the bottom of the freezing area 120 through the blowing operation of the turbo fan 230. The second compressor 212 located in the flows to cool the second compressor (212). Then, the outside air after cooling the second compressor 212, the refrigerator main body 100 through the outlets 151 formed in the rear cover 150 covering the machine room region 140 in the rear of the main body 100 Can be discharged to the rear of the.

Meanwhile, as mentioned above, the defrost water storage containers 510 and 520 are installed at the bottom of the refrigerating area 110 and the freezing area 120 according to the present invention. At the bottom of the refrigerating region 110, a first defrosting water storage container 510 for storing defrosted defrosted water in the refrigerating region 110 is installed. The first defrost water storage container 510 is connected to the refrigerating region 110 and the pipe (P). In addition, a second defrosting water storage container 520 is installed at the bottom of the freezing area 120 to store defrosted water in which the frost in the freezing area 120 is melted. The second defrost water storage container 520 is connected to the freezing area 120 and the pipe (P).

In particular, the first defrost water storage container 510 is disposed at the bottom of the second area ② of the space between the pair of compressors 211 and 212, and the second defrost water storage container 520 is a second compressor. 212 is installed to be in close contact with the upper end.

Therefore, the second defrost water storage container 520 is installed in a fixed state at the upper end of the second compressor 212, thereby securing a predetermined space around the second compressor 212, and thus various pipes (not shown). Can be used as an installation space for

In addition, the second defrosting water storage container 520 may be melted and stored in the second defrosting water storage container 520 to form a temperature below a predetermined temperature. Accordingly, the second defrost water storage container 520 may further cool the second compressor 212 that dissipates a predetermined heat when compressing the refrigerant.

That is, the outside air in front of the refrigerator is sucked into the first region ① from the bottom of the refrigerator main body 100 through the suction ports 420 of the condenser cover 400 by the suction force of the turbo fan 230. The outside air sucked into the first region ① cools the condenser 220. At this time, the outside air may be raised to a predetermined temperature during cooling. As such, the outside air after cooling the condenser 220 flows to the second region ② to spread and cool the first compressor 211. At this time, the outside air may further increase the temperature while cooling the first compressor (211).

The outside air after cooling the first compressor 211 flows through the turbo fan 230 to the second compressor 212. In this case, the outside air passes through the first defrost water storage container 510 disposed between the first and second compressors 211 and 212, and the refrigerating area 110 stored in the first defrost water storage container 510. It can be lowered to a constant temperature by exposure to defrost water having cold air discharged from it.

As such, the outdoor air passing through the first defrost water storage container 510 and the turbo fan 230 may flow to the second compressor 212 to cool the second compressor 212.

In this case, since the outside air may be raised to a predetermined temperature while cooling the condenser 220 and the first compressor 211, the external compressor may not achieve normal cooling efficiency when the second compressor 212 is cooled. Accordingly, in the present invention, the second defrosting water storage container 520, in which defrost water below a predetermined temperature is stored, is tightly fixed to the upper end of the second compressor 212, thereby allowing the second defrosting water storage container 520 to store the second defrost water storage container 520. The compressor 212 is further cooled to solve this problem.

In addition, the first defrost water storage container 510 may be fixed to the upper end of the first compressor 211 so as to further cool the first compressor 211.
