Abstract

PURPOSE:To reduce electric power consumption by constitution wherein large air convection holes are provided in the centers on the left and right sides of the slanted sections of a machine room cover while air hole nets are attached to the centers of the left and right holes. CONSTITUTION:A machine room cover 24 is provided with an air hole 28 and a left net center on the left side of a slanted section while another air hole 30 and another net 31 are provided in the center on the right side of the slanted section. A left frame 32 and a right frame 33, wrapping the end surfaces of the left net 29 and the right net 31, are provided in the centers on the left side and right side of the slanted sections of the machine room cover 24 so as to be contacted with the fixed to the peripheral rims of the air holes 28, 30 while a projection 34 is provided to restrict abutment against a wall 35. The fan 26 of a fan motor 25 at the vicinity of a compressor 21 is rotated and cooling airflow, generated by the fan 26, enters through the left 29 attached to the air hole 28 in the center on the left side of slanted section of cover 24. Then, the cooling air is cooling against the end face of the compressor 21 and flows along the outer periphery of the compressor 21 but one part of the cooling air passes between a shielding 27 and the compressor 21. Further, the cooling air is discharged through the right net 31 attached to the air hole 30 in the center on the right side of slanted sections of the machine room cover 24.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator mechanical compartment cover for cooling a refrigerator compressor with a fan.

[0002]

2. Description of the Related Art A conventional structure will be described below with reference to the drawings. FIG. 5 is a longitudinal sectional view of essential parts of a refrigerator of a conventional example, FIG. 6 is a lateral sectional view of essential parts of a refrigerator of a conventional example, and FIG. 7 is a rear view of a machine room cover of the conventional example.

The compressor 1 has a cylindrical shape and is horizontally arranged in the machine room 3 below the refrigerator main body 2, and a machine room cover 4 is attached to the lower rear surface of the refrigerator main body 2. A fan 6 is attached to and installed on a fan motor 5 beside the compressor 1. In front of the compressor 1 is a shielding plate 7. On the other hand, in the machine room cover 4, a plurality of air convection holes 8 are formed and provided with a convex portion 9 so that the air convection holes 8 contact the wall 10 when the refrigerator is installed.

The machine room cover of the refrigerator configured to cool the compressor configured as described above by the fan will be described below.

When a fan 6 attached to a fan motor 5 on the side of the compressor 1 rotates and the cooling air from the fan 6 hits the end face of the compressor 1 and runs along the outer periphery of the compressor 1, both of them are part of the cooling air. Passes between the shielding plate 7 and the compressor. The cooling air is radiated from a plurality of the air convection holes 8 of the machine room cover 4 and the gap between the convex portion 9 and the lower part of the refrigerator main body 2 to the upper part thereof.

[0006]

However, in the above configuration, when the refrigerator is installed in a system kitchen or the like, the conditions for installing the refrigerator become strict, and the cooling air from the fan does not sufficiently hit the outer periphery of the compressor. Since the heat is not sufficiently radiated from the plurality of air convection holes provided in the cover and the compressor is not effectively cooled, there is a problem that the operating rate of the refrigerator increases and the power consumption increases.

In view of the above problems, the present invention provides a mechanical room cover for a refrigerator that consumes less power.

[0008]

In order to solve the above-mentioned problems, the mounting structure of the machine room cover of the present invention has a large air convection hole formed at the center of the left and right of the inclined portion of the machine room cover, and at the same time, it is formed. An air vent net is attached to the center.

[0009]

According to the present invention, with the above-described structure, the cooling air generated from the fan enters from the hole of the left net of the inclined portion of the machine chamber cover and is blown to the outer peripheral portion of the compressor, and the heat of the compressor is generated by Heat can be easily dissipated outside the refrigerator from the hole in the right net of the inclined part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a longitudinal sectional view of an essential part of a refrigerator according to an embodiment of the present invention, FIG. 2 is a lateral sectional view of an essential part of a refrigerator according to an embodiment of the present invention, and FIG. 3 is a machine according to an embodiment of the present invention. FIG. 4 is a rear view of the chamber cover, and FIG. 4 is a partial perspective view of the net according to the embodiment of the present invention.

In these figures, the compressor 21 has a cylindrical shape and is horizontally arranged in a machine room 23 below the refrigerator body 22, and a machine room cover 24 is attached to the lower rear surface of the refrigerator body 22. ing. Next to the compressor 21,
A fan 26 is attached to the fan motor 25. In front of the compressor 21, there is a shielding plate 27.

On the other hand, the machine room cover 24 is provided with an air hole 28 and a left net 29 in the left center of the inclined portion, and an air hole 30 is provided with a right net 31 in the right center of the inclined portion.
9 and the left frame 32 and the right frame 33 that wrap around the end faces of the right net 31 are closely fixed to the air hole 28 in the left center of the inclined portion of the machine chamber cover 24 and the peripheral edge of the air hole 30 in the right center of the inclined portion. The structure is provided so that the protrusion 34 is provided and the contact with the wall 35 is set when the refrigerator is installed.

A machine room cover of a refrigerator for cooling the compressor 21 having the above-mentioned structure with a fan will be described below.

The fan 26 of the fan motor 25 next to the compressor 21 rotates, and the cooling air from the fan 22 has a left net 29 having an air hole 28 attached to the left center of the inclined portion of 24.
As the cooling air comes in and hits the end face of the compressor 21 and runs along the outer periphery of the compressor 21, a part of the cooling air is blocked by the shield plate 27 and the compressor 21.
Pass through The cooling air has a structure that radiates heat from a right net 31 attached to an air hole 30 at the center of the slope of the machine room cover on the right.

[0016]

As described above, according to the present invention as described above, the cooling air generated from the fan enters from the left net attached to the air hole at the left center of the inclined portion of the cover of the machine room, and the cooling air of the compressor is discharged. In order to easily radiate the heat of the compressor to the outside of the refrigerator from the right net attached to the air hole in the center on the right of the inclined part of the cover of the machine room,
(EN) Provided is a structure for mounting a machine room cover that effectively cools a compressor, reduces the operating rate of a refrigerator, and reduces power consumption.
