Abstract

PURPOSE:To lessen restrictions on a place of installation of an outdoor unit and also to moderate a possible offensive view thereof by lessening the vertical height of the outdoor unit. CONSTITUTION:The inside of a unit case 1 is partitioned into left and right sides by a partition plate 15 and thereby a machine chamber 9 is formed on one side and a heat exchange chamber 10 on the other. A laterally-long and rectangular air heat exchanger 2 is disposed vertically or obliquely inside the heat exchange chamber 10, while a tangential fan 8 rotating around the horizontal axis is disposed above the air heat exchanger 2. Inside the machine chamber, a compressor, a control box and others are disposed.

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. The inside of the casing 01 of the outdoor unit 100 is divided into left and right by a partition plate 08, and a machine room 09 is formed on the right side and a heat exchange chamber 010 is formed on the left side.

A rectangular air heat exchanger is provided in the heat exchange chamber 010.
02, a propeller fan 03 and a motor 07 for driving the propeller fan 03 are arranged in front of it. The air heat exchanger 02 is vertically erected so as to face the air suction port 011 formed on the back surface 01a of the casing 01.

Further, the propeller fan 03 is arranged so as to face an air outlet 012 formed in the front panel 01C of the casing 01. A bell mouth 04 is attached around the air outlet 012.

In the machine room 09, in addition to the compressor 05, the control box 06,
An accumulator, a discharge muffler, a four-way valve, a receiver, an expansion valve and the like (not shown) are provided.

When the propeller fan 03 is rotationally driven by the motor 07, outside air is sucked into the heat exchange chamber 010 through the air suction port 011 and is heated by exchanging heat with the refrigerant while passing through the air heat exchanger 02. Alternatively, after the temperature is lowered, it is urged by the propeller fan 03 and discharged from the air outlet 012 to the outside.

[0007]

In the conventional outdoor unit 100 described above, since the propeller fan 03 has a large diameter, the vertical height of the casing 01 becomes large. Therefore, if the outdoor unit 100 is set on the ground, the height of the equipment casing 01 is higher than that of the pedestal of the house, so it must be installed in a place without the pedestal, and therefore the installation place of the outdoor unit 100 is restricted. There was a problem. Further, even when the outdoor unit 100 is installed on the eaves of the house, there is a problem in that the upper and lower heights of the device casing 01 are uncomfortable.

[0008]

The present invention has been invented in order to solve the above-mentioned problems. The gist of the first invention is to partition the inside of the casing by a partition plate to the left and right. By forming a machine room on one side and a heat exchange room on the other side, and arranging a horizontal rectangular air heat exchanger vertically or obliquely in the heat exchange room and above the air heat exchanger with a horizontal axis. The outdoor unit of an air conditioner is characterized in that a tangential fan that rotates around is disposed, and a compressor, a control box, and the like are disposed in the machine chamber.

It is possible to form an air intake port in the lower front portion of the heat exchange chamber and an air outlet in the upper front portion.

The air inlets may be formed in the lower front portion and the lower front portion of the heat exchange chamber, and the air outlets may be provided in the upper front portion.

The gist of the second aspect of the invention is to provide an air outlet in the upper front part of the heat exchange chamber formed by partitioning the inside of the casing with an partition plate, and an air intake port in the lower part thereof. By disposing a guide plate inside the heat exchange chamber, an air passage extending from the air suction port to the air outlet is formed, and an air heat exchanger is arranged in the air passage and the air heat The outdoor unit of the air conditioner is characterized in that a tangential fan is arranged on the downstream side of the exchanger.

A machine room for accommodating a compressor, a control box and the like can be formed laterally to the heat exchange chamber accommodating the air heat exchanger and the tangential fan.

[0013]

When the tangential fan is driven during operation of the air conditioner, outside air is sucked into the heat exchange chamber through the air suction port, and the temperature is raised or lowered by passing through the air heat exchanger. It is urged by the Tanzen Char Juan and blown out from the air outlet.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIG. 1
Is a rectangular parallelepiped casing, which is horizontally longer and has a lower vertical height than the conventional casing 01. The inside of this container 1 is a partition plate 15
Is divided into left and right sides, and a machine room 9 is formed on the right side and a heat exchange room 10 is formed on the left side.

An air outlet is provided in the upper part of the front surface 1C of the heat exchange chamber 10.
12 is provided, an air suction port 11 is provided in the lower part thereof, and an air suction port 13 is also provided in the front part of the lower surface 1d.

A U-shaped air passage 14 extending from the air inlets 11 and 13 to the air outlet 12 is formed by the guide plate 16 disposed inside the heat exchange chamber 10. This air passage 14 is formed. A horizontal rectangular air heat exchanger 2 is obliquely installed therein, and a tangential fan 8 rotating around a horizontal axis is installed above the air heat exchanger 2 and on the downstream side thereof. Further, in the machine room 9, a compressor 5, a control box 6, a drive motor 7
Etc. are provided.

When the tangential fan 8 is driven by the motor 7, however, outside air enters the air flow path 14 in the heat exchange chamber 10 from the air suction ports 11 and 13 and flows through the air heat exchanger 2. After raising or lowering the temperature by exchanging heat with the refrigerant, it is energized by the tangential fan 8.
It is blown out from the air outlet 12.

In the above-mentioned embodiment, the air heat exchanger 2 is installed obliquely, but it may be installed vertically.
Further, the air suction port 13 can be omitted.

[0019]

According to the present invention, the inside of the housing is partitioned by the partition plate to the left and right to form the machine room on one side.
A heat exchange chamber is formed on the other side, a horizontal rectangular air heat exchanger is vertically or obliquely arranged in the heat exchange chamber, and a tangential fan rotating around a horizontal axis is provided above the air heat exchanger. Since the compressor and the control box are arranged in the machine room, the vertical height of the casing can be reduced. As a result, when installing the outdoor unit on the ground,
The restrictions on the installation place are reduced, and even when the outdoor unit is installed on the eaves, it can be prevented from becoming an eyesore.

If an air inlet is formed in the lower front part of the heat exchange chamber and an air outlet is formed in the upper front part, no space for introducing outside air is required behind the housing, so that the outdoor unit can be installed. Space can be reduced.

If the air inlets are formed in the lower front portion and the lower front portion of the heat exchange chamber and the air outlets are provided in the upper front portion, the outside air is not limited to the air inlet formed in the lower front portion of the heat exchange chamber. Since a large amount of outside air can be smoothly introduced into the heat exchange chamber because the air intake port formed in the front portion of the lower surface can also be sucked into the heat exchange chamber, the degree of freedom in the installation posture of the air heat exchanger is expanded.

By disposing a guide plate inside the heat exchange chamber, an air flow path from the air suction port to the air outlet is formed, and an air heat exchanger is disposed in the air flow path. By arranging the tangential fan on the downstream side of the air heat exchanger, the outside air sucked from the air inlet can be smoothly passed through the air heat exchanger and the tangential fan and discharged from the air outlet. .
