Abstract

PURPOSE:To improve an outer appearance of an outdoor device and perform an effective cooling of equipment stored in a control box by a method wherein a handle is applied as a dimpled type handle recessed inside a side surface and a deep side of the dimpled handle is provided with a cold air taking-inlet port. CONSTITUTION:A side surface of a device casing 1 is provided with a dimpled handle 20 recessed inside the surface. A deep side of the dimpled handle 20 is provided with a cold air taking-in port 21. Accordingly, the dimpled handle 20 is not projected out of the surface of the side surface, the cold air taking-in port 21 is not seen from side part, resulting in that its outer appearance is improved. Cold air is taken at the cold air taking-in port 21 arranged at the deep side of the dimpled handle 20 and smoothly sucked into a control box 6, resulting in that equipment (such as control board 16 and radiation fins 19 or the like) in the control box 6 can be effectively cooled.

Description

Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art An example of an outdoor unit of a conventional separation type air conditioner is shown in FIG. 2, where (A) is a partially cutaway front view, (B) is a right side view, and (C). Is a cross-sectional view and (D) is a partially enlarged view of (C). The inside of the cabinet 1 of the outdoor unit is partitioned into left and right by a partition plate 2, and the machine room 3 is provided on one side thereof.
However, the heat exchange chamber 4 is formed on the other side.

An L-shaped heat exchanger 9, a blower fan 10, a motor 14 and the like are arranged in the heat exchange chamber 4. The L-shaped heat exchanger 9 is opposed to an air intake 11 formed on the back panel 1a of the housing 1 and an air intake 12 formed on the left side panel 1b. Further, the blower fan 10 is arranged so as to face the air outlet 13 formed in the front panel 1c of the housing 1.

A compressor 5, a control box 6 and the like are arranged in the machine room 3. The compressor 5 is supported on the base 1d of the casing 1 via a vibration-proof support mechanism 31, and the control box 6 is arranged above the compressor 5 and adjacent to the right side panel 1e. This control box 6
The terminal block 37 for connecting the electrical wiring for connection to the indoor unit is installed on the right side of the
As shown in, the power transistor 15, the control board 16, and the radiation fin 19 for cooling the power transistor 15 are housed. Reference numeral 18 is also a radiation fin for cooling the power transistor 15, which is exposed in the cooling air passage of the heat exchange chamber 4.

A lid for covering the control box 6
38 is detachably attached to the right side panel 1e, and a handle 32 for carrying the outdoor unit is projectingly provided on the lid 38, and a cooling air inlet 33 to the control box 6 is provided.
Is provided.

When the blower fan 10 is rotationally driven by the motor 14, the outside air is sucked into the heat exchange chamber 4 through the air inlets 11 and 12, and is heated by exchanging heat with the refrigerant in the process of passing through the heat exchanger 9. After being heated or cooled, it is urged by the blower fan 10 to be discharged to the outside from the air outlet 13.

At the same time, part of the outside air flowing through the heat exchanger 9 flows around the heat radiation fins 18 to cool it. On the other hand, the outside air sucked into the machine room 3 from the cooling air intake 33 enters the control box 6 through the intake port 34 formed in the control box 6, and flows around the control board 16 and the radiation fins 19. And after cooling them,
The gas is discharged to the air outlet 13 through the exhaust port 35 formed in the control box 6 and the exhaust port 36 formed in the partition plate 2.

[0008]

In the above-mentioned conventional outdoor unit, since the handle 32 and the cooling air intake 32 are provided on the right side surface 1e of the casing 1, these impair the aesthetics of the outdoor unit and control it. There is a problem that the substrate 16 and the radiation fin 19 cannot be cooled effectively.

[0009]

The present invention has been invented to solve the above-mentioned problems, and the gist of the present invention is to dispose a control box adjacent to the side surface in a container case. In an outdoor unit of an air conditioner having a carrying handle on the side surface and a cooling air inlet to the control box, the concave handle is formed as a concave handle recessed inward from the side surface. The outdoor unit of an air conditioner is characterized in that the cooling air intake is provided at the back of the handle.

[0010]

In the present invention, because of the above-described structure, the cooling air is taken into the machine room from the cooling air intake provided at the back of the concave handle and flows through the control box to the inside. Cool down the equipment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. 1, where (A) is a partially cutaway front view and (B) is a right side view. A piping space 41 is formed by partitioning the machine room 3 with a partition wall 40. The piping space 41 is formed on the right side panel 1e.
It is adapted to be covered by a pipe cover 42 which is detachably attached to the.

A terminal space 37 for connecting electrical wiring for connection to an indoor unit and operation valves 43, 44 for connecting a refrigerant pipe for connection to an indoor unit are built in the piping space 41. It is attached to the partition wall 40.

The pipe cover 42 is provided with a concave handle 20 which is recessed inward from the outer surface thereof, and a cooling air inlet 21 is provided in the inner portion of the concave handle 20, and the partition wall 40 is opposed to this.
Is provided with a cooling air intake 22. Other configurations are similar to those of the conventional one shown in FIG. 2, and corresponding members are designated by the same reference numerals.

However, the cooling air is cooled by the cooling air intakes 21 and 22.
The air is sucked into the machine chamber 3 through the inlet, enters the control box 6 through the air inlet 34, cools the control board 16, the radiation fins 19 and the like therein, and is then discharged through the air outlets 35 and 36.

[0015]

According to the present invention, since the concave handle which is recessed inward from the surface is provided on the side surface of the housing and the cooling air intake is provided at the back of the concave handle, the concave handle is provided on the side surface. Since it does not project from the surface and the cooling air intake is not visible from the side, the appearance of the outdoor unit can be improved.

Further, since the cooling air is taken in from the cooling air inlet provided in the inner part of the concave handle and smoothly sucked into the control box, the equipment in the control box can be effectively cooled.
