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 air conditioner is shown in FIG. 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.

A compressor 5 and the like are arranged in the heat exchange chamber 3. In the heat exchanger chamber 4, an L-shaped heat exchanger 9, a propeller fan 10, a motor 14 and the like are arranged.

The L-shaped heat exchanger 9 is opposed to an air intake 11 formed on the rear surface 1a of the casing 1 and an air intake 12 formed on the left side 1b. The propeller fan 10 is arranged so as to face the air outlet 13 formed on the front surface 1c of the housing 1.

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

[0006]

In the outdoor unit of the conventional air conditioner described above, when the heat exchangers 9 are arranged in multiple rows in order to improve the heat exchange capacity, the width of the casing 1 increases. there were. There is also a problem that the noise of the propeller fan 10 is dissipated from the outlet 13 to the outside of the casing 1. Further, if the user accidentally puts his or her hand through the outlet 13, there is a risk of contacting the propeller fan 10 and getting injured.

[0007]

The present invention has been invented in order to solve the above-mentioned problems, and its gist is to divide the inside of the chamber of an outdoor unit into left and right by partition plates. An air conditioner in which a heat exchange chamber is formed on one side and a machine room is formed on the other side, a heat exchanger and a blower are arranged in the heat exchange chamber, and a compressor and the like are arranged in the machine chamber. In the outdoor unit of, at least two heat exchangers are arranged in the heat exchange chamber so as to face the air outlet formed on the front surface of the device housing and the air intake formed on the rear surface of the device housing, respectively. The blower is installed in the space between the two heat exchangers, and the machine room is formed on one side of the blower so that at least a part of the machine room is contained in the space between the heat exchangers. The outdoor unit of the air conditioner Located in.

Another feature is that the partition plate is provided so as to be curved from one end of both heat exchangers to the space side,
The compressor is installed in this curved space so that a part of it is located.

[0009]

In the present invention, when the blower is driven, the outside air is taken into the heat exchange chamber from the air intake, the heat exchanger facing the air intake is passed through to raise or lower the temperature, and then the blower is turned on. After being urged, the heat exchanger facing the air outlet is passed therethrough to raise or lower the temperature, and then discharged from the air outlet to the outside.

DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIG. By partitioning the inside of the housing 1 with a partition plate 20, a heat exchange chamber 24 is formed on the left side and a machine room 23 is formed on the right side.
An air intake 16 is formed so as to communicate with the heat exchange chamber 24 over most of the left side of the rear surface 1a of the device casing 1 and the latter half of the left side surface 1b, and most of the left side of the front surface 1c and the left side surface 1b. An outlet 17 is formed over the first half of the.

An L-shaped heat exchanger 18 is disposed in the heat exchange chamber 24 so as to face the air intake 16, and the air outlet is provided.
An L-shaped heat exchanger 19 is arranged so as to oppose to 17.

The blower 10 is installed in the space between the heat exchangers 18 and 19 and is rotationally driven by the motor 14. Partition board
By bending 20 from the right end of these heat exchangers 18 and 19 to the space side between them, the machine room 23 is formed so that a part thereof fits in the space, and the compressor 5 has a part thereof It is installed so that it is located in the curved space of room 23.

When the blower 10 is driven, the outside air is drawn into the heat exchange chamber 24 through the air intake 16 and the heat exchanger 18
After raising or lowering the temperature by passing through the
Then, the temperature is raised or lowered by passing through the heat exchanger 19 and then discharged from the blow-out port 17 to the outside.

However, in this outdoor unit,
Since the machine room 23 is formed so that a part thereof is accommodated in the space between the heat exchangers 18 and 19, the width of the device casing 1 can be made smaller than that of the conventional device. Not only can the size be reduced, but the air flow areas of the heat exchangers 18 and 19 can be expanded, and the diameter of the blower 10 can be increased.

Further, since the heat exchangers 18 and 19 are arranged in front of and behind the blower 10, the noise generated from the blower 10 can be suppressed by the heat exchangers 18 and 19, and therefore, the outside of the casing 1. It is possible to reduce the noise radiated to the. Furthermore, the outlet
Since the heat exchanger 19 is provided at 17, the blower 10 is not injured by touching the hand with the hand.

The outdoor unit can be installed upside down, and the blower 10 can be reversed to suck the outside air through the air outlet 17 and blow out through the air inlet 16.

Further, although the heat exchangers 18 and 19 are each arranged in one row, they may be arranged in two or more rows, and these are formed in a flat plate shape on the rear surface 1a and the front surface 1c of the housing 1. It is also possible to arrange along.

[0018]

According to the present invention, since the machine room is formed so that a part of the machine room fits in the space between the heat exchangers, not only can the lateral width of the housing be made smaller. It is possible to increase the air circulation area of the heat exchanger and increase the diameter of the blower.

Further, since the heat exchanger is arranged so as to face the air outlet, noise emitted from the air outlet can be reduced and injury due to accidental entry of the hand through the air outlet can be prevented.
