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 wire condenser and a compressor by supplying outside air into a machine room at a lower portion of a lower portion of a refrigerator main body through a duct provided at a lower portion of the lower refrigerator main body. About.

[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 machine room 5 is constituted by surrounding the recess 2 formed in the lower back portion of the cabinet body 1 with the bottom plate 3 and the back cover 4, and the cooling fan 6 is provided in the machine room 5.
And a compressor 7, and a duct 8 communicating with the machine room 5 is formed at a lower portion of the main body 1.
Is provided with a wire capacitor 9. The front surface of the duct 8 is an outside air intake 10.

However, in this device, the cooling fan 6
As shown by arrows in FIG. 5, the outside air is sucked from the outside air intake 10 and is introduced into the machine room 5 through the duct 8, and is formed on the back cover 4 constituting the back wall of the machine room 5. By discharging from the discharge port 11, the wire condenser 9 and the compressor 7 are cooled.

[0004]

However, in the prior art, since the outside air intake 10 in the duct 8 is formed on the front surface, the sound in the machine room 5, especially the sound of the cooling fan 6, is reduced. There was a problem that the noise directly came out of the room from 10 and the noise was loud.

In this type of refrigerator, when manufacturing models having different capacities, the width is changed, and in consideration of such circumstances, the wire 9a of the wire capacitor 9 is directed in the front-rear direction. In this way, the width can be easily changed. However, in this case, a portion where the wire 9a does not exist occurs at both left and right end portions of the wire capacitor 9.

For this reason, if the outside air intake 10 is formed on the front surface, the outside air passing through the duct 8 will
From 0, the portion 8a on the cooling fan 6 side where the ventilation resistance is small
(Part where the wire 9a is not present in the wire capacitor 9)
It will flow intensively directly to In this case, heat exchange between the outside air and the wire 9a is deteriorated, and cooling efficiency for the wire condenser 9 is deteriorated.

As a countermeasure, as shown in FIG. 6, a shielding plate 12 is provided inside the duct 8, thereby restricting the flow of the outside air as shown by the solid line arrow, and the heat exchange efficiency with the wire condenser 9. To increase.

However, this requires a lot of man-hours for manufacturing and assembling, resulting in high costs.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a refrigerator capable of preventing noise leakage and improving heat exchange efficiency without using a shielding plate. is there.

[0010]

According to the refrigerator of the present invention, a compressor and a cooling fan are provided in a machine room provided at a lower part of a lower part of a refrigerator main body, and a duct leading to the machine room is provided at a lower part of the refrigerator main body. A wire condenser having a wire oriented in the front-rear direction is disposed in the duct, and outside air is introduced into the machine room through the duct by the operation of the cooling fan and discharged from a discharge port formed in a rear wall portion of the machine room. The cooling of the wire condenser and the compressor by performing
The machine room and the duct communicate with the cooling fan corresponding part
It is characterized in that a suction port is formed and an outside air intake is formed on a side surface of the duct opposite to the suction port .

[0011]

According to the above means, since the outside air intake is formed on the side surface of the duct, the sound in the machine room does not directly come out of the outside air intake, so that noise leakage can be reduced. .

In particular, since the outside air inlet is formed on the side opposite to the suction port , the outside air flowing into the duct from this outside air inlet flows so as to intersect with the wire, thereby increasing the cooling efficiency for the wire condenser. be able to. Further, a conventional shielding plate for changing the flow path can be omitted, and the number of manufacturing steps and the number of assembling steps can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The refrigerator main body 21 is set so as to be separated from the floor surface by the legs 22,
A recess 21 a is formed in a lower part of the lower part of the storage body 21. A machine room 25 is formed by closing the bottom of the recess 21a with a compressor base 23 as a bottom plate and closing the back with a back cover 24 as a back wall.

A front left portion of the compressor stand 23 ;
That is, the cooling fan 31 (described later) in the machine room 26
A suction port 23a is formed in the corresponding portion . A discharge port 26 is formed on the right side of the rear cover 24,
An auxiliary intake port 24a is formed on the left side.

The inside of the machine room 25 is formed by a partition plate 27 into a left chamber 25a and a right chamber 25b, and a bell mouth 28 is formed in the partition plate 27. A blower motor 29 is provided on the partition plate 27, and a blade 30 is attached to a rotating shaft of the blower motor 29 so as to correspond to the bell mouth 28. The blower motor 29 and the blades 30 constitute a cooling fan 31. A compressor 32 is provided in the right chamber 25b.

At the lower part of the storage body 21, the machine room 2
5 is provided. The duct 33 is configured by joining a duct case 34 to the lower surface of the cabinet main body 21 without any gap.

In the duct 33, a wire condenser 3 is provided.
5 are provided. The wire capacitor 35 has a configuration in which the wire 35a is directed forward and backward. In the duct 33, an outside air inlet 36 is formed on a side surface opposite to the suction port 23a .

In the above configuration, when the cooling fan 31 is operated, as shown by arrows in FIGS. 1 and 2, the outside air flows below the side plate 21a of the storage body 21, the outside air inlet 36,
It is sucked into the left chamber 25a of the machine chamber 25 through the suction port 23a in the duct 33, and is sent into the right chamber 25b through the bell mouth 28 to be discharged from the discharge port 26. Thereby, the wire condenser 35 and the compressor 32 are cooled.

According to the present embodiment, the outside air inlet 36 is formed on the side opposite to the suction port 23a , so that the outside air flowing into the duct 33 from the outside air inlet 36 can be prevented. It flows so as to intersect with the wire 35a, so that the cooling efficiency for the wire condenser 35 can be increased.

Further, since the outside air intake 36 is provided on the side surface of the duct 33, the sound in the machine room 25 does not directly come out of the outside air intake 36, thereby reducing noise leakage. be able to. According to the present embodiment, the conventional shielding plate for changing the flow path can be dispensed with, so that the number of manufacturing steps and the number of assembling steps can be reduced, which can contribute to cost reduction.

[0021]

As is apparent from the above description, the present invention provides that a cooling fan corresponding portion in a machine room is
Form a suction port that communicates with the
And characterized in that the formation of the fresh air inlet to the side of the mouth opposite, which at, prevents noise leakage, or
Also, the outside air that has flowed into the duct from the outside air intake
Can cross the wire of the capacitor
Heat exchange effect with wire capacitor without using shield plate
This leads to an excellent effect that the rate can be improved and the number of manufacturing steps and the number of assembling steps can be reduced.
