Abstract

PURPOSE:To enable a degree of freedom in design of a refrigerant pipe to be improved and further an operating valve bracket to be mounted at an optional position by a method wherein a connecting end part of the refrigerant pipe to the operating valve is fixed to a base. CONSTITUTION:A refrigerant pipe 15 connecting a compressor 15 with an operating valve 17 is fixed to a base 1d having a high strength and a high rigidity with a fixing fitting 21 near the operating valve 17. Due to this fact, even if the compressor 5 is vibrated and this vibration is transmitted to the refrigerant pipe 15 during an operation of an air conditioner, the vibration is not be transmitted over a fixing position for the base 1d. With such an arrangement as above, since a stress acting against the refrigerant pipe 15 subsequent to the fixed position is reduced, a degree of freedom in design of the refrigerant pipe 15 can be improved, the operating valve bracket 16 can be set at an optional position, for example, the right side surface 1e of the device casing 1.

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 housing 1 of the outdoor unit is partitioned into a left side and a right side by a partition plate 2, and a machine room 3 is formed on one side and a heat exchanger room 4 is formed on the other side.

A compressor 5 and the like are disposed in the machine room 3, and an L-shaped heat exchanger 9, a blower fan 10, and the like are provided in the heat exchanger room 4.
A motor 14 and the like are provided.

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

The operation valve bracket 16 is fixed to the base 1d so as to be located at the lower rear of the right side surface 1e of the casing 1, and a pair of operation valves 17 and 18 are attached to the operation valve bracket 16. The compressor 5 is installed on the base 1d, and the compressor 5 is connected to an operation valve 17 through a refrigerant pipe 15 and an unillustrated expansion valve, a capillary tube, a four-way switching valve, a refrigerant device such as a receiver. It is connected. After installing this outdoor unit in a predetermined position outdoors, the operation valves 17, 18
The outdoor unit is connected to an indoor unit (not shown) by connecting a pair of connection pipes 19 and 20 to.

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

[0007]

When the compressor 5 vibrates during the operation of the conventional air conditioner, this vibration causes the refrigerant piping.
15 may be transmitted to the refrigerant equipment and damaged. Therefore, in order to deal with this, the operation valve bracket 16
Was fixed to the base 1d with high strength and rigidity,
There is a problem that the mounting positions of the operation valves 17 and 18 are restricted. Also, the refrigerant pipe 15 may be lengthened to form a loop,
A rubber mass or a damper sealant is attached to the refrigerant pipe 15 to limit its vibration, but these have a problem that the cost increases.

[0008]

SUMMARY OF THE INVENTION The present invention has been invented to solve the above problems, and its gist is to provide a compressor installed on a base and an operation valve at the other end. In the outdoor unit of an air conditioner having a connecting refrigerant pipe, the vicinity of a connecting end of the refrigerant pipe to the operation valve is fixed to the base, and the outdoor unit of the air conditioner is characterized.

[0009]

In the present invention, since it has the above-mentioned structure, the vibration transmitted to the refrigerant pipe after the fixing position to the base is reduced.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENT One embodiment of the present invention is shown in FIG. The refrigerant pipe 15 connecting the compressor 5 and the operation valve 17 is fixed to the base 1d having a large strength and rigidity near the operation valve 17 by the fixing metal fitting 21. Other configurations are the same as the conventional ones.

Thus, when the air conditioner is in operation, the compressor 5
Vibrates, and even if this vibration propagates to the refrigerant pipe 15, it does not propagate beyond the fixed position to the base 1d. Therefore, since the stress acting on the refrigerant pipe 15 after the fixed position is reduced, the degree of freedom in designing the refrigerant pipe 15 is improved and the operation valve bracket 16 is placed at any position, for example, the right side surface 1e
Can be installed in

[0012]

According to the present invention, since the vicinity of the connection end of the refrigerant pipe to the operation valve is fixed to the base, the vibration transmitted to the refrigerant pipe after this fixing position is reduced. As a result, the stress acting on the refrigerant pipe after the fixed position is reduced, so that the degree of freedom in designing the refrigerant pipe is improved and the operation valve bracket can be installed at an arbitrary position.
