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 an air conditioner is shown in FIG.
, (A) is a partially cutaway front view, (B)
Is a longitudinal sectional view taken along line BB of (A), (C) is CC of (A).
A transverse sectional view taken along the line, (D) is a right side view.

The inside of the enclosure 20 of the outdoor unit is vertically divided by a partition plate 21, a machine chamber 22 is formed below the partition plate 21, and a heat exchange chamber 23 is formed above the partition plate 21.

In the heat exchange chamber 23, a heat exchanger 26, a blower 27,
A motor 25 and the like are provided. The heat exchanger 26 has a U-shaped cross section, and is arranged close to the rear surface 20a of the housing 1 to form an air intake port 28a formed in the rear surface 20a of the housing 20.
, The air intake port 28b formed on the left side surface 20b and the housing 20
Are opposed to the air intakes 28c formed on the right side surface 20c. The blower 27 is installed so as to face the exhaust port 29 formed in the front surface 20d of the casing 20.

A control box (not shown), a capillary tube, a discharge muffler, an accumulator, a receiver, a four-way switching valve, and a horizontal compressor 24 are provided in the machine room 22.
And the like are arranged, and the compressor 24 is vibration-proof supported on the bottom plate 20e of the housing 20 via a vibration-proof support mechanism 31.

At the lower part of the right side surface 20c of the casing 20, an operation valve 32,
A pair of refrigerant pipes 34, 35 to which the operation valves 32, 33 are attached are guided to an indoor unit (not shown) through a gap between the rear surface 20a of the housing 20 and the wall surface 36 of the building.

When the blower 27 is rotationally driven by the motor 25, the outside air is sucked into the heat exchange chamber 23 through the air intakes 28a, 28b, 28c and exchanges heat with the refrigerant in the process of passing through the heat exchanger 26. After raising or lowering the temperature by
And is discharged to the outside through the exhaust port 29.

[0008]

In the above conventional outdoor unit, the refrigerant pipe 34 connected to the operation valves 32, 33,
35 is guided to the indoor unit through the gap between the back surface 20a of the housing 20 and the wall surface 36, and the heat exchanger 26 is connected to the back surface 20a of the housing 20.
, The outdoor unit must be installed at a distance l of at least 50 mm or more between the rear surface 20a and the wall surface 36 in order to take in air from the air intake port 28a. There was a problem that the installation space for the outdoor unit was large.

The operation valves 32 and 33 are provided on the right side surface 20c of the casing 20.
Since the refrigerant pipes 34 and 35 are connected to the refrigerant pipes 34 and 35, there is a problem that the appearance of the outdoor unit is impaired and the width of the outdoor unit is increased.

[0010]

The present invention has been invented in order to solve the above-mentioned problems, and the gist of the present invention is to divide the inside of the casing by a partition plate so that the machine room is located below it. In the outdoor unit of the air conditioner in which a heat exchange chamber is formed above and a heat exchanger having a U-shaped cross section is arranged in the heat exchange chamber on the back side of the casing. At least between the back of the container and the container
An operation valve for connecting a refrigerant pipe for connecting with an indoor unit is arranged in the device casing at a distance of 30 mm, and an outlet of the refrigerant pipe connected to the operation valve is provided in the device casing. It is an outdoor unit of an air conditioner characterized by being formed on the upper surface of the.

[0011]

In the present invention, since it has the above-mentioned structure, the outside air flows into the heat exchanger through the space between the rear surface of the casing and the heat exchanger. The refrigerant pipe connected to the operation valve is taken out to the outside through an outlet formed on the upper surface of the container case and guided to the indoor unit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention is shown in FIG. 1, (A) is a top view, (B) is a right side view with a pipe cover removed,
(C) is a plan view taken along the line CC of (B). As shown in FIG. 1 (A), the heat exchanger 26 having a U-shaped cross section is installed in the heat exchange chamber 23 at a distance γ of at least 30 mm from the back surface 20a of the housing 20.

The lower space of the partition plate 21 is divided into a machine room 22 and a piping space 38 by a partition wall 37 as shown in FIGS. (B) and (C), and the operating valves 32 and 33 are partitioned by a partition wall in the piping space 38. It is attached to 37. And this piping space
38 is closed by a pipe cover 39 which is detachably attached to the container case 20. Further, an outlet 40 is formed at the right rear corner of the upper surface of the device casing 20.

However, this outdoor unit is installed in a state where there is almost no distance δ between the rear surface 20a of the housing 20 and the wall surface 36 of the building. Then, remove the piping cover 39 and operate the operation valve.
A pair of refrigerant pipes 34, 35 are connected to 32, 33. The refrigerant pipes 34, 35 penetrate the partition plate 21 and enter the heat exchange chamber 23,
It is shown through a space formed between the right corner of the U-shaped heat exchanger 26 and the right rear corner of the housing 20 and taken out upward from an outlet 40 formed on the upper surface of the housing 20. Not guided to the indoor unit. Other configurations are similar to those of the conventional one shown in FIG. 2, and corresponding members are designated by the same reference numerals.

Therefore, the heat exchanger 26 is installed on the rear surface 20a of the housing 20.
Since it is arranged at a distance γ of at least 30 mm between the air and the air, the outside air sucked into the heat exchange chamber 23 from the air inlets 28a, 28b and 28c flows into the U-shaped heat exchanger 26 through the distance γ. .

Further, the operation valves 32 and 33 are built in the housing 20, and the refrigerant pipes 34 and 35 connected to the operation valves 32 and 33 pass through the inside of the housing 20 and an outlet formed on the upper surface thereof. Since it is taken out from 40, it is not necessary to pass it through the back of the casing 20 as in the conventional case. As a result, since the equipment casing 20 can be installed near the wall surface 26 of the building, the installation space of the outdoor unit can be saved.

Further, since the operation valves 32 and 33 are arranged in the container case 20 and the refrigerant pipes 34 and 35 connected thereto are also passed through the container case 20, the appearance of the outdoor unit is improved and the outdoor unit is improved. The installation space is also reduced.

The air inlet 28a formed on the rear surface 20a of the container 20 can be omitted, and as shown in FIG. 1 (A), the air can be provided on the upper surface of the container 20 along the rear edge thereof. Intake
28f can be formed. Further, the operation valves 32 and 33 can be arranged in the space between the corner portion of the heat exchanger 26 and the rear corner of the casing 20.

[0019]

According to the present invention, since the heat exchanger is arranged at a distance of at least 30 mm from the back surface of the housing, the outdoor unit can be installed close to the wall surface of the building. The installation space can be saved. Further, since the operation valve is built in the housing and the refrigerant pipe connected to the operation valve is taken out through the inside of the housing through the outlet formed on the upper surface of the housing, the appearance of the outdoor unit can be improved. It can be improved and the installation space of the outdoor unit can be reduced.
