DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator for cooling a compressor and a wire condenser by blowing air sucked from a duct containing a wire condenser into a machine room containing a compressor.

[0002]

2. Description of the Related Art Some recent refrigerators have a cooling structure for a compressor and a condenser as shown in FIGS. That is, the refrigerator body 1
A machine room 4 in a form surrounded by a bottom plate 2 and a back cover 3 is provided in the lower part of the lower part of the refrigerator, and a duct 6 communicating with the machine room 4 through a vent 5 is formed below the refrigerator body 1. A cooling fan 7 and a compressor 8 are provided in the chamber 4, and a wire condenser 9 is accommodated in the duct 6. An exhaust port 3a is formed in the rear cover 3 at a position opposite to the ventilation port 5 with the compressor 8 interposed therebetween, and an outside air inlet 6a is formed in a front surface of the duct 6, for example.

In such a configuration, the cooling fan 7
Is operated, the outside air sucked through the outside air inlet 6a flows through the duct 6, is then blown toward the compressor 8 through the ventilation port 5, and then discharged outside through the exhaust port 3a. As a result, the wire condenser 9 and the compressor 8 are cooled.

[0004]

In the above-described conventional configuration, only the cooling efficiency of the compressor 8 is emphasized and the cooling fan 7
Is configured so that the center of the air blowing direction is coincident with the center of the compressor 8, which causes the following problems.

In other words, the presence of the compressor 8 impedes the flow of air from the cooling fan 7, which lowers the efficiency of air blowing by the cooling fan 7. Will be reduced. For this reason, the cooling effect of the cooling fan on the wire condenser 9 is reduced, and the heat radiation efficiency is deteriorated.
Is remarkable when the size is inevitable such as the reciprocating form.

The present invention has been made in view of the above circumstances, and has as its object to generate an air flow in a duct using a cooling fan that blows air toward a compressor, and to cool the wire condenser by the air flow. It is an object of the present invention to provide a refrigerator that is configured to perform the above-described process and that can improve the heat radiation efficiency of the wire condenser while keeping the cooling efficiency of the compressor within a certain range.

[0007]

According to the present invention, in order to achieve the above-mentioned object, a duct accommodating a wire condenser is communicated with the duct at a position separated from the duct by a compressor disposed therein. A machine room in which a vent and an exhaust port communicating with the outside are formed, and the machine room is provided so as to blow air to the compressor, and the air sucked from the vent in response to the air blowing operation is used as the exhaust port. in a refrigerator having a cooling fan for discharging through the cooling fan, the exhaust is the center of the blowing direction
The compressor is arranged so as to be offset from the center of the compressor so as to substantially coincide with the air port .

[0008]

When the cooling fan is operated, air is blown toward the compressor to cool the compressor. At the time of such a blow, air is sucked into the machine room from the air vent communicating with the duct. Accordingly, a flow of air is generated in the duct, and the cooling of the wire condenser is performed by the air flow, and the air sucked into the machine room is discharged from the exhaust port to the outside. Become like In this case, since the cooling fan is arranged so as to be offset from the center of the compressor so that the center in the blowing direction is substantially coincident with the exhaust port, the flow of the wind by the cooling fan is Is hardly hindered by the compressor, and the air blowing efficiency of the cooling fan is increased. For this reason, the amount of air flowing in the duct increases, and the cooling effect of the cooling fan on the wire condenser is enhanced, thereby improving the heat radiation efficiency of the wire condenser. In this case, although the cooling capacity of the compressor by the cooling fan is reduced, the air from the cooling fan is still applied to the compressor, so that the cooling efficiency of the compressor can be kept within a certain range.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 2, the refrigerator body 11 has a bottom plate 12 and a back cover 1
3 is provided, and a duct 1 is provided at a lower portion so as to be adjacent to the machine room 14.
5 are provided, and the machine room 14 and the duct 15
The space is communicated by a vent 16 (see FIG. 1) at a portion near the side. An axial cooling fan 17 and a reciprocating compressor 18 are provided in the machine room 14, and a wire condenser 19 is provided in the duct 15.
Is stored. An evaporating dish 20 for storing defrost water from a cooler (not shown) is provided at an upper portion in the machine room 14.
It is configured to be evaporated by the heat from the air.

In FIG. 1, an exhaust port 13a is formed in the rear cover 13 at a position opposite to the ventilation port 16 with the compressor 18 interposed therebetween. Are formed.

Here, the direction of the cooling fan 17 is
Center (indicated by S) is substantially coincident with the exhaust port 13a
Cormorant are arranged to be offset being shifted by an angle θ from the center C of the compressor 18 to the exhaust port 13a side. A partition plate 21 having a bell mouth 21 a for the cooling fan 17 is provided in the machine room 14.
The partition plate 21 is also arranged in a state of being inclined by an angle corresponding to the offset angle θ of the cooling fan 17 as described above.

In the above configuration, the cooling fan 1
When the air conditioner 7 is operated, the outside air sucked through the outside air inlet 15a flows into the duct 15, and then is sucked into the machine room 14 through the ventilation hole 16 and is blown toward the compressor 18. Thereafter, the air is discharged from the exhaust port 13a to the outside, whereby the wire condenser 19 and the compressor 18 are cooled.

[0013] In this case, the cooling fan 17, the air blowing direction
Since the center of the direction is arranged so as to be offset from the center of the compressor 18 toward the exhaust port 13a by the angle θ, the flow of the wind by the cooling fan 17 is hardly obstructed by the compressor 18, and the cooling fan 1
7 increases the blowing efficiency. For this reason, the amount of air circulation in the duct 15 increases, and the cooling effect of the cooling fan 17 on the wire condenser 19 is enhanced, so that the heat radiation efficiency of the wire condenser 19 is improved. . In this case, although the cooling capacity of the compressor 18 decreases,
Is blown from the cooling fan 17, so that the cooling efficiency of the compressor 18 can be kept within a certain range.

Moreover, in order to obtain such an effect, it is only necessary to arrange the cooling fan 17 so as to be in an offset state shifted by an angle θ, so that there is no need to change the space in the machine room 14. There is.

Further, since the compressor 18 is not transiently cooled, there is no possibility that the evaporation capacity of the stored defrost water by the evaporating dish 20 is reduced. As a result, there is no problem even if the capacity of the evaporating dish 20 is reduced, and the size of the machine room 14 can be reduced.

Although the above-described embodiment has been described with reference to an example in which a reciprocating compressor is used as the compressor 18, it is needless to say that the same effect can be obtained by using a rotary compressor.

[0017]

According to the present invention, as is apparent from the above description, an air flow is generated in a duct using a cooling fan that blows air toward a compressor, and the wire flow in the duct is generated by the air flow. With a very simple configuration that only changes the arrangement of the cooling fans, the cooling efficiency of the wire condenser can be improved while maintaining the cooling efficiency of the compressor within a certain range. It is possible to achieve such an excellent effect.
