Abstract

PURPOSE: To simplify the structure of an outdoor unit and to eliminate stagnancy heat in a machine chamber wherein a compressor and a pressure reducing device are held, by a method wherein an electrical component protecting cover of the outdoor unit is made to be of a rotary type and to have a size large enough to close up an opening of the machine chamber. CONSTITUTION: An outdoor unit for an air conditioner which is constructed of a compressor 1, a nonuse-side heat exchanger 2, a pressure reducing device 3, a blower 4, an electrical component box 5, an electrical component protecting cover 6 and an outer plate cover 7 can prevent excessive outdoor air from penetrating into the unit, by making the electrical component protecting cover 6 rotate to close up an opening of a machine chamber when inspection or checkup of a state of operation is needed, in a state wherein the outer plate cover 7 is removed. By removing a partition plate of the machine chamber provided so far between the side of the compressor 1 and the pressure reducing device 3 and the side of the blower 4 and the nonuse-side heat exchanger, in this way, a structure is simplified and stagnancy heat on the side of the compressor 1 and the pressure reducing device 3 can be eliminated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner.

[0002]

2. Description of the Related Art A conventional technique is an air conditioner (Japanese Patent Laid-Open No. 5-1
As disclosed in Japanese Patent Application No. 72389 and Japanese Patent Application No. 3-340643), by having a means for changing the number of rotations of the outdoor blower, the number of rotations of the outdoor blower can be increased when the outdoor air temperature is high. Although it prevents the temperature from rising, no consideration was given to heat buildup in the machine room.

[0003]

The above-mentioned prior art aims to prevent the temperature rise inside the outdoor electric article, and does not take into consideration the heat buildup in the machine room.

An object of the present invention is to simplify the structure of the outdoor unit and eliminate the heat buildup in the machine room containing the compressor and the pressure reducing device.

[0005]

In order to achieve the above object, the present invention uses a rotary type outdoor unit electrical equipment protective cover, and has a size capable of preventing the opening of the machine room.

[0006]

[Function] When it is necessary to inspect and confirm the operating condition with the outer cover removed, the electrical equipment protective cover is of the rotary type,
By making the shape so that the machine room opening can be closed, the machine room opening can be prevented, and excess outdoor air can be prevented from entering the unit. Further, conventionally, it is provided between the compressor, the pressure reducing device side, the blower, and the non-use side heat exchanger side,
By eliminating the machine room partition plate, the heat buildup on the compressor and decompressor side is eliminated.

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

FIG. 1 shows a compressor 1, a non-use side heat exchanger 2,
FIG. 3 is an internal structural diagram of an outdoor unit for an air conditioner, which includes a decompression device 3, a blower 4, an electrical component box 5, an electrical component protective cover 6, and an outer plate cover 7. Inspection and operation with the outer plate cover 7 removed. When it is necessary to check the state, the electrical equipment protection cover 6 is rotated to close the opening of the machine room, so that excess outdoor air can be prevented from entering the unit. Further, FIG. 2 shows a compressor 1 ', a non-use side heat exchanger 2', a pressure reducing device 3 ', a blower 4', an electric component box 5 ', an electric component protective cover 6', an outer plate cover 7 ', a machine room. FIG. 3 is an internal structural view of an outdoor unit for an air conditioner that is configured by a partition plate 8. When an inspection and an operation state are required to be checked with the outer plate cover 7 ′ removed, the electrical component protection cover 6 ′ also needs to be removed. There is. Further, the machine room partition plate 8 prevents excess outdoor air from passing through the unit even when the outer cover 7'is removed during operation. However, when the outer cover 7'is attached, the compressor 1 ' In some cases, the heat generated in 1 is accumulated in the machine room on the side of the compressor 1'and the pressure reducing device 3 '. In FIG. 1, since it is not necessary to provide the machine room partition plate 8 in FIG. 1, the structure is simplified as compared with FIG. 2, and the heat buildup on the compressor 1 and pressure reducing device 3 sides can be eliminated.

[0009]

According to the present invention, the compressor, the pressure reducing device side,
By eliminating the machine room partition plate that was provided between the blower and the non-use side heat exchanger side, the structure was simplified,
It is possible to eliminate the heat buildup on the side of the compressor and pressure reducing device.
