BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator which is provided with a machine room in the lower inner part of the refrigerator body, and which is equipped with a compressor and a blower.

0003

2. Description of the Related Art Refrigerators are equipped with a machine room at the bottom of the main body, and a compressor and a blower inside the machine room. The compressor is provided to be cooled. This machine has an inlet on the left front side of the machine room and an outlet on the right front side, and outside air is drawn into the machine room through the inlet, cools the compressor (after heat exchange) ) exits from the outlet. Since this kind of device allows outside air for cooling to be taken in and discharged from the front of the refrigerator main body, it is also suitable for placing the rear surface of the refrigerator main body close to the wall of the kitchen and the right and left sides close to walls or furniture. Therefore, it is often used as a so-called built-in type.

[Problems to be Solved by the Invention] However, in the above configuration, a so-called short circuit occurs in the lower part of the machine room, in which the outside air after heat exchange from the machine room re-enters the machine room, resulting in a decrease in cooling performance for the compressor. There's a problem.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a refrigerator that can improve the cooling performance of the compressor.

[Configuration of the invention]

[0007]

[Means for Solving the Problems] The refrigerator of the present invention has a machine room having an inlet and an outlet on the front side formed in the lower deep part of the refrigerator body, a compressor and a blower provided in this machine room, and The compressor is cooled by causing outside air to flow into and exhaust the machine room using a blower, wherein a duct is provided only for the suction port, and the duct and the compressor are located at the same height. It is characterized by its structure.

[0008]

[Operation] According to the above means, since the duct is provided at the suction port, the suction port and the discharge port are separated. As a result, the outside air from the machine room after heat exchange does not flow back into the machine room, and noise can be reduced.

Furthermore, since the duct is provided only at the suction port, air blowing resistance is small, unlike the case where ducts are provided at both the suction port and the discharge port. Furthermore, since the duct is provided at the inlet rather than the outlet, unlike when the duct is provided at the outlet, the outside air after heat exchange is not oriented in one direction, which does not cause discomfort to the user. In addition, since the duct and the compressor are configured to be at the same height, the air blowing resistance can be reduced compared to when there is a height difference between them, and overall air blowing performance and compressor cooling performance can be improved. Can be done.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS. 1 to 3. In FIG. 2, a closed machine room 2 is formed in the lower deep part of the storage body 1. As shown in FIGS. 1 and 3, the inside of the machine room 2 is partitioned left and right by a partition plate 3, with an inlet 4 formed in the front of the left-hand chamber 2a, and an inlet port 4 formed in the front and rear surfaces of the right-hand chamber 2b. In this case, discharge ports 5 and 6 are formed. Furthermore, in the right chamber 2b, a compressor 7 consisting of a rotary compressor is disposed on the bottom plate 2c.

The blower 8 is composed of a motor 8a and a fan 9, and the blower 7 is installed in the machine room 2 such that the fan 9 is located within a vent 10 formed in the partition plate 3. ing.

A duct 11 communicating with the suction port 4 is formed by a flat cylinder 12 at the lower part of the refrigerator body 1, and this duct 11 is open at the front of the lower part of the refrigerator body 1. This duct 11 and the compressor 5 are set to be at the same height. A capacitor 14 connected to the compressor 5 via a delivery pipe 13 is disposed in the duct 11. A refrigerator having such a configuration is installed, for example, with the rear surface of the refrigerator main body 1 close to a wall in the kitchen, and the left and right side surfaces close to a wall or furniture.

[0013] The action will be described. When the blower 8 is operated in conjunction with the operation of the compressor 7, outside air flows into the left chamber 2a through the duct 11 and the suction port 4, as shown by the arrow, and is discharged through the vent 10 into the right chamber 2b. , the compressor 7 is cooled (heat exchanged), and the discharge port 5,
Leave from 6. Note that when the outside air passes through the duct 11, it also cools the condenser 14.

[0014] Since the storage body 1 is installed with the rear surface close to a wall of a kitchen or the like, outside air particularly exits from the front exhaust port 5 of the exhaust ports 5 and 6. Additionally, when installing the refrigerator body 1, it is common to make the storage width larger than its width by a margin, so the side side of the refrigerator body 1 is generally wider than the rear side. It is. Therefore, the outside air after heat exchange that comes out of the front exhaust port 5 flows not only to the front side but also to the sides, that is, it is diffused.

As described above, according to this embodiment, since the duct 11 is provided at the inlet 4, the inlet 1 and the outlet 5
It has a partitioned form. As a result, the outside air after heat exchange coming out of the machine room 2 will not flow back into the machine room 2, and furthermore, noise can be reduced.

Furthermore, since the duct 11 is provided only at the suction port 4, air blowing resistance can be reduced, unlike the case where ducts are provided at both the suction port 4 and the discharge port 5. Furthermore, since the duct 11 and the compressor 7 are configured to be at the same height, the air blowing resistance can be reduced compared to when there is a height difference between them, and the air blowing performance can be improved overall. . Therefore, the blower 8 can be made smaller in order to obtain the same cooling performance as the conventional one.

In particular, according to this embodiment, since the condenser 14 is provided in the duct 11, the cooling capacity for the condenser 14 is also increased.

FIG. 4 shows a second embodiment of the present invention, in which the delivery pipe 21
This embodiment differs from the first embodiment in that it is connected to the compressor 14 in the duct 11 through the front part A of the discharge port 5 on the lower surface of the storage body 1. According to this second embodiment, the space occupied by the delivery pipe 21 in the duct 11 is reduced, and the size of the condenser 14 disposed in the duct 11 can be increased accordingly, making it possible to increase the heat exchange efficiency of the condenser 14. .

FIG. 5 shows a third embodiment of the present invention. In this third embodiment, an oil cooler 31 is provided to cool the oil in the compressor 7. Discharge port 5 on the bottom surface of main body 1
It differs from the first embodiment in that it is disposed at the front region A. According to this third embodiment, the effect of cooling the compressor 7 by the oil cooler 31 can be obtained, and the heat exchange efficiency of the heat radiation part 31a in the oil cooler 31 can be increased, and the cooling performance of the compressor 7 by the oil cooler 31 can be improved. This effect is achieved.

[0020]

Effects of the Invention As is clear from the above description, the present invention forms a machine room having an inlet and an outlet on the front side in the lower deep part of the storage body, and a compressor and a blower are installed in this machine room. , in which the compressor is cooled by causing outside air to flow into and exhaust the machine room using the blower, a duct is provided only for the suction port, and the duct and the compressor are located at the same height. With this structure, it is possible to improve the cooling performance and to reduce noise, which is an excellent effect.
