Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilation structure for a refrigerator in a machine room.

[0002]

2. Description of the Related Art Conventionally, as for a machine room ventilation structure for cooling a compressor of a refrigerator by a fan motor for cooling a compressor, for example, as disclosed in JP-A-60-16286, a compressor for cooling a compressor mounted beside the compressor is used. The fan motor has a structure in which generated wind is blown to radiate heat.

A conventional structure as described above will be described below with reference to the drawings. FIG. 4 is a longitudinal sectional view of a main part of the conventional example, and FIG. 5 is a lateral sectional view of the conventional example.

Reference numeral 1 is a cylindrical compressor. Two
Is an outer box that forms a top surface and both side surfaces, and forms a contour with a machine room top wall 3 that forms a back surface and a bottom surface. And outer box 2
A heat insulating material 5 is filled in the inner walls of the machine room top wall 3 and the inner box 4 to form a refrigerator body 6. The compressor 1 is arranged in a horizontal position in front of the machine room 7 below the main body 6, and a machine room cover 8 is attached to the lower rear surface of the refrigerator main body 6. A cooling fan motor 9 for the compressor 1 is attached and installed beside the compressor 1.
In front of the compressor 1 is a shielding plate 10 which is spaced from the floor of the installation site. In front of the shield plate 10 is a condenser 11.

On the other hand, the machine room cover 8 has an air convection hole 12
However, a plurality of moldings are provided, and a convex portion 13 that protrudes from the back wall of the main body 6 is provided, so that the refrigerator is used as a system kitchen
It is a structure that restricts the contact with the system kitchen 14 when installed.

The ventilation structure of the refrigerator constructed as described above in the machine room will be described below.

The air blown inside the machine room 7 generated by the rotation of the compressor cooling fan motor 9 mounted beside the compressor 1 hits the side surface of the compressor 1 along the outer circumference of the compressor 1 and a part of the wind. Passes between the shielding plate 10 and the compressor 1. The wind radiates from the air convection holes 12 of the machine room cover 8 and from the lower part to the upper part of the refrigerator body 6 through the gap of the convex portion 13, and a part of the wind circulates in the machine room 7. ing.

[0008]

However, in the above-mentioned configuration, when the refrigerator is installed in the system kitchen, the gap between the refrigerator and the wall is reduced and the installation conditions of the refrigerator become strict. Therefore, the amount of cold air sucked from the lower part of the refrigerator main body is reduced, and it is mixed with the heat radiation from the condenser installed at the lower part of the refrigerator main body, and the cold air from the compressor cooling fan motor does not sufficiently hit the outer periphery of the compressor,
Heat is not sufficiently dissipated from the multiple holes provided in the machine room cover,
Since the compressor is not cooled efficiently, 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 concentrates heat from the convection holes of the machine room cover, efficiently cools the compressor, reduces the operation rate of the refrigerator, and reduces power consumption. It provides a ventilation structure.

[0010]

In order to solve the above-mentioned problems, the machine room ventilation structure of the present invention is provided with several cut-and-raised parts having holes at the tip from the top wall of the machine room, and ducts are provided in the holes. It will be constructed by mounting.

[0011]

According to the present invention, due to the structure described above, the duct on the lower surface of the lower part of the refrigerator does not mix the intake of cold air from the lower front part of the refrigerator body with the heat radiation from the condenser installed at the lower part of the refrigerator body.

Therefore, the cool air from the lower front portion of the refrigerator main body directly hits the outer periphery of the compressor by the compressor cooling fan motor and radiates heat efficiently. Further, the invention provides a ventilation structure in the machine room in which heat is concentrated and discharged from the convection holes of the machine room cover, the compressor is efficiently cooled, the operating rate of the refrigerator is reduced, and the power consumption is reduced. .

[0013]

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

The same components as those of the conventional example are designated by the same reference numerals and detailed description thereof will be omitted.

A plurality of cut-and-raised parts 17 are provided with holes 16 at the tip from the top wall 15 of the machine room, and ducts attached to the holes 16 are provided between the condenser 11 and the outer case 2.

Therefore, the intake of cold air from the lower front portion of the refrigerator body 6 and the heat radiation from the condenser 11 installed at the lower portion of the refrigerator body 6 do not mix. Therefore, cool air is sucked from the front lower part of the refrigerator body 6 by the fan motor 9 for cooling the compressor, and directly hits the outer periphery of the compressor 1 to radiate heat efficiently. Moreover, the compressor is efficiently cooled by concentrating heat from the convection holes 12 of the machine chamber cover 8 and radiating heat.

[0017]

As described above, according to the ventilation structure of the refrigerator in the machine room according to the present invention, the duct having the above-described structure is provided with the cut-and-raised portion having a hole at the tip of the ceiling wall of the machine room. As a result, the intake of cold air from the lower front portion of the refrigerator body and the heat radiation from the condenser installed at the lower portion of the refrigerator body do not mix.

In addition, it is possible to prevent adverse effects such as an excessively high temperature inside the condenser. Therefore, the cool air from the lower front part of the refrigerator main body is sucked by the fan motor for cooling the compressor, and is blown to the outer circumference of the compressor to be efficiently radiated. Moreover, the heat is concentrated and radiated from the convection holes of the machine room cover, the compressor is efficiently cooled, the operating rate of the refrigerator is lowered, and the power consumption can be reduced.
