Hereinafter, a refrigerator of the present invention will be described with reference to the accompanying drawings.

1 to 3, a refrigerator according to the present invention includes a refrigerator body 100 in which a refrigerating area 110, a freezing area 120, a machine room area 140 are formed, And a refrigeration cycle device 200 installed in the refrigeration cycle apparatus 200.

The refrigerating area 110 and the freezing area 120 are partitioned by a first partition 131 formed in the refrigerator body 100. The machine room area 140 is located at the bottom of the refrigerating area 110 and the freezing area 120 and has a predetermined space at the rear end of the refrigerator body 100.

Here, a bottom frame 160 is installed on the bottom of the refrigerator main body 100.

The machine room area 140 is divided into a first area ① between the refrigerating area 110 and the lower frame 160 and a second area ② on the rear end side of the refrigerating and freezing areas 110 and 120 . Here, the rear ends of the refrigerating / freezing regions 110 and 120 are formed to be upwardly inclined from the lower end thereof to the upper end thereof.

In the present invention, the condenser 220 of the refrigeration cycle apparatus 200 is disposed in the first region (1), and the plurality of compressors 210 are disposed in parallel in the second region (2).

First, the arrangement of the condenser 220 in the first region (1) will be described.

A heat insulating foam 300 having a predetermined thickness is foamed in the lower frame 160 of the refrigerator body 100. The heat insulating foam 300 located below the refrigerating area 110 is formed with an insertion groove 310 into which the condenser 220 is inserted. Accordingly, the condenser 220 is inserted and positioned in the insertion groove 310. Accordingly, the upper end of the condenser 220 is exposed to the first region (1).

A condenser cover 400 is installed at a predetermined position of the lower frame 160 where the condenser 220 is located. The condenser cover 400 may be bolted to the lower frame 160 to open and close the opening 161 formed in the lower frame 160. Accordingly, the lower end of the condenser 220 can be exposed through the opening 161 in the bottom space of the refrigerator main body 100.

Here, as shown in FIG. 4, the condenser cover 400 has a rectangular tube-shaped cover body 410 with an open upper side. The cover body 410 is inclined downward at a predetermined angle along the downward direction from the rim and has a space with a certain depth on the inside. The suction holes 420 are formed on the side walls of the cover body 410.

The suction holes 420 are formed in the front body of the cover body 410 so as to be spaced apart from each other by at least one of the front suction ports 421 formed at the front side wall of the cover body 410 at regular intervals, And side suction inlets 422 formed by the suction holes 422. The front suction ports 421 may be formed to pass through the bottom of the refrigerator body 100 toward the front of the refrigerator body 100.

In this case, the side air inlets 422 are formed to have a width (half of the length of the side wall of the condenser cover 400) facing the front side of the refrigerator body 100 And a front portion corresponding to the front portion). This is to prevent the inflow of the heated outside air from the area outside the rear end of the refrigerator main body 100 where the compressors 210 are located.

The condenser 220 is exposed at the bottom of the refrigerator body 100 due to the inlets 420 formed in the condenser cover 400 and the inlets 420 are disposed in front of the refrigerator body 100 (A) capable of guiding outdoor air in the refrigerator body 100 to the side of the condenser 220 through the bottom of the refrigerator body 100 can be formed.

Next, the arrangement state of the compressors 210 in the second area (2) will be described.

The second region (2) is communicated with the first region (1).

The pair of compressors 210 may include a first compressor 211 and a second compressor 212. The first compressor 211 is disposed in the machine room area 140 to be positioned at the bottom of the refrigerated area 110 and the second compressor 212 is disposed in the bottom of the refrigerated area 110, (140). The upper ends of the first and second compressors 211 and 212 are formed in a dome shape.

In addition, a turbo fan 230 is installed in the machine room area 140 where the second area (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 certain distance.

The turbo fan 230 sucks the outside air into the first region (1) and forcibly flows the air into the second region (2) so that the rear cover (200) installed at the rear of the mechanical room region (140) 150 to the outside through an outlet 151. The outlet 151 may correspond to the rear of the freezing region 120 of the rear cover 150. In this process, the sucked outside air cools the condenser 220 in the first region (1), and the outside air flowing into the second region (2) cools the first compressor (211) To cool the second compressor 212 and to be discharged to the outside through the discharge port 151.

In this case, the first and second compressors 211 and 212 in the second region (2) are disposed at a predetermined distance from the turbo fan 230, and are sequentially arranged at predetermined intervals in the outside air flowing from the first region (1) , The outside air flow resistance in the second region (2) can be reduced, and the compressor cooling efficiency can be increased.

Further, a turbo fan 230 is mounted between the compressors 210 in the second region (2). Here, the turbo fan 230 may be disposed between the refrigerating region and the freezing region.

Here, the first region (1) and the second region (2) in the present invention are communicated with each other, the condenser 220 is disposed on the front side of the refrigerator main body 100, And is disposed on the rear side of the main body 100. The position of the condenser 220 and the position of the turbo fan 230 may be different from each other.

The turbo fan 230 is a fan having no shroud, and has a blowing ability higher than a predetermined level. For example, the turbo fan 230 may use a fan having a blowing capacity of about 60% or more as compared with the case where the compressor 210 is a single compressor.

When the turbo fan 230 is operated in a state of being positioned between the pair of compressors 210, the outside air is sucked into the first region (1) through the condenser (220) And flows through the first compressor 211 and the second compressor 212 located at the side of the turbo fan 230. [ The outside air passing through the second compressor 212 forms a flow path a which is discharged to the outside through a discharge port 151 formed in the rear cover 150 installed at the rear end of the mechanical room area 140.

Particularly, the reason why the turbo fan 230 has a blowing capacity of about 60% or more compared to when the compressor 210 is a single compressor is that the compressors 210 for compressing the refrigerant in the second region (2) 230 are spaced apart from each other by a predetermined distance, so that the amount of heat generated therefrom is increased so as to cool them efficiently.

In addition, the first and second raw water storage containers are installed in the second area.

The first dehydrated water storage vessel is installed between the first compressor and the second compressor and is connected to the refrigerating area to store a certain amount of defrosted water generated from the evaporator at the refrigerating area side. The first dehydrated water storage vessel has a drain pipe exposed to the outside of the refrigerator body to discharge dehydrated water to the outside.

The second dehydrated water storage vessel is closely fixed to the upper end of the second compressor and connected to the freezing region to store a certain amount of freezing water of frost generated from the evaporator at the freezing region side. The second dehydrated water storage vessel has a drain pipe exposed to the outside of the refrigerator body to discharge dehydrated water to the outside.

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

1 and 2, a refrigeration cycle apparatus 200 according to the present invention is disposed in a machine room area 140 partitioned from refrigeration / freezing areas 110 and 120, and the machine room area 140 is divided into a first area ①) and the second area (②). Here, it is preferable that the clearance in the up and down direction of the first region (1) is smaller than the clearance of the second region (2).

Since the condenser 220 is installed in the insertion groove 310 of the heat insulating foam 300 formed in the lower frame 160 in the first region 1, . That is, the contents of the refrigerator can be increased by the installation area of the condenser 220. In addition, since the refrigerant is located at the bottom of the refrigerating area 110, the heat transfer area can be increased to a certain level or more.

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

In the present invention, the outside air flow path (a) connecting the first region (1) and the second region (2) can be formed. This allows the outside air to flow through the inlet of the condenser cover 400 (420). ≪ / RTI >

That is, when the turbo fan 230 having a blowing capability equal to or greater than a predetermined level is operated, a predetermined suction force is generated in the first and second areas. The outside air in front of the refrigerator body 100 flows into the bottom of the refrigerator body 100 and then sucked into the inside of the condenser cover 400 through the inlets 420 of the condenser cover 400. [

The air inlets 420 through which the outside air is forcibly sucked are composed of front air inlets 421 directed to the front of the refrigerator body 100 and side air inlets 422 directed to both sides of the refrigerator body 100, Particularly, the side air inlets 422 have a width corresponding to half of both sides of the condenser cover 400 (the width toward the front of the refrigerator body 100), that is, the width of the front half of the side wall of the condenser cover 400 The outside air at the rear end of the refrigerator in which the compressors 210 are installed can be prevented from being directly sucked.

In other words, the condenser cover 400 according to the present invention is configured such that the outside air at the front side of the refrigerator main body 110, which is at a temperature lower than a predetermined temperature or lower than the outside air at the rear end of the refrigerator corresponding to the position where the compressors 210, So that the condenser 220 can be exposed to the outside air flowing in from the front of the refrigerator.

Accordingly, the condenser 220, which generates heat by condensing the refrigerant, can be primarily cooled by the suction of the outside air as described above.

The outside air sucked through the inlets 420 of the condenser cover 400 cools the condenser 220 in the first region (1) and flows into the second region (2).

At this time, since the width (the height of the first area) of the first area (1) is narrower (lower) than the width of the second area (2) The flow rate of the outside air in the region (1) can be increased to a certain level or more while continuing to the second region (2). When flowing from the first region (1) to the second region (2), the outside air can be spread in the second region (2).

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

First, the outside air flowing into the second area (2) cools the first compressor (211) located at the bottom of the refrigeration area (100) and flows through the bottom part of the freezing area (120) To a second compressor (212) located in the second compressor (212) to cool the second compressor (212). The outside air after cooling the second compressor 212 is discharged from the refrigerator body 100 through the discharge openings 151 formed in the rear cover 150 covering the machine room area 140 from the rear of the main body 100, As shown in Fig.

Meanwhile, as described above, the respective defrost water storage vessels 510 and 520 are installed at the bottom of the refrigerating zone 110 and the freezing zone 120 according to the present invention. A first dehydrated water storage vessel 510 is installed at the bottom of the refrigerated area 110 to store defrosted water in the refrigerated area 110. The first dehydrated water storage vessel 510 is connected to the refrigerating zone 110 by a first pipe P1. In the bottom of the freezing zone 120, a second defrosting water storage vessel 520 is installed in which freezing water dissolved in the freezing zone 120 is stored. The second dehydrated water storage vessel 520 is connected to the freezing region 120 by a second pipe P. [

In particular, the first dehydrated water storage vessel 510 is disposed at the bottom of the second area (2) of the space between the pair of compressors 211 and 212, (212).

Accordingly, since the second decompressed water storage vessel 520 is fixedly installed at the upper end of the second compressor 212, a certain space is secured around the second compressor 212, and various pipes (not shown) As shown in FIG.

Also, the second defrost water storage container 520 may contain a frost having a cold temperature of less than a predetermined temperature, so that the temperature of the second defrost water storage container 520 may be lower than a predetermined temperature. Accordingly, the second dehydrated water storage vessel 520 may further cool the second compressor 212 that dissipates a certain amount of heat when the refrigerant is compressed.

That is, the outside air in front of the refrigerator is sucked from the bottom of the refrigerator main body 100 to the first area (1) through the inlets 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 can be raised to a certain temperature upon cooling. The outside air after cooling the condenser 220 spreads while flowing to the second region (2) and cools the first compressor 211. At this time, the outdoor air may be further raised in temperature while cooling the first compressor 211.

The outside air after cooling the first compressor 211 flows to the second compressor 212 through the turbo fan 230. At this time, the outside air passes through a first dehydrated water storage vessel 510 disposed between the first and second compressors 211 and 212, and then flows into the refrigerated area 110, which is stored in the first dehydrated water storage vessel 510, It is possible to lower the temperature to a predetermined temperature.

As described above, the outside air passing through the first effluent storage container 510 and the turbo fan 230 flows to the second compressor 212 to cool the second compressor 212.

At this time, since the outside air can be raised to a certain temperature while cooling the condenser 220 and the first compressor 211, normal cooling efficiency may not be achieved when the second compressor 212 is cooled. Accordingly, in the present invention, the second decompressed water storage container 520 storing the decomposed water at a predetermined temperature or less is closely fixed to the upper end of the second compressor 212, The compressor 212 is further cooled so that the above problem can be solved.

In addition, the first dehydrated water storage vessel 510 may be fixedly attached to the upper end of the first compressor 211 so as to further cool the first compressor 211.
