In the air conditioner configured as described above, since the compressor (6) is fixed to the base plate (10) via the vibration isolator (14), the compressor (6) is started, operated, and stopped. The vibration of time is attenuated and transmitted to the base plate (10).

It has a structure that shuts off.

[Problems to be solved by the device]

Since the conventional air conditioner is configured as above,
When two compressors are operated at the same time, the operating vibrations of the compressors are attenuated through the vibration isolator and transmitted to the base plate, but each vibration interferes with one base plate and is amplified periodically. The generated vibration was generated. Further, the amplified vibration vibrates the air between the base plate and the bottom plate, and eventually the bottom plate also resonates with this vibration, which causes an abnormal sound when the air conditioner is operated, which is a quality problem.

The present invention has been made to solve the above problems, and it is possible to reduce the transmission of the operating vibration of the compressor to the bottom plate. Furthermore, the operating vibration causes the bottom plate to resonate and no abnormal noise is generated. The purpose is to obtain a perfect air conditioner.

[Means for solving the problem]

This invention has a bottom plate formed by folding four sides into a dish shape, a left side panel, a rear panel, a right side panel, and a top panel fixed to the upper part of the panel. , And a box body composed of a front panel that is easily fixed to the front surface, a pair of compressors housed in the box body, and a refrigerant that is provided corresponding to each of the compressors and returns to the compressor. In an air conditioner having an accumulator for separating gas and liquid, a refrigerant supplied from the compressor, and a non-use side heat exchanger for exchanging heat with a fluid to be heat exchanged, the bottom plate via a cushioning material. A pair of left and right base plates and a compressor mounting plate attached to each of the base plates via a vibration isolator II, and each of the compressor mounting plates includes a vibration isolator I. The compressor is attached.

[Action]

In the air conditioner according to the present invention, the base plate for fixing the compressor and the accumulator is divided into two, and the vibration isolator II is used.
A compressor mounting plate is attached to each of the base plates via a vibration damping material I, and a compressor is attached to each of the compressor mounting plates via a vibration isolator I. However, since it is attenuated by the vibration isolator I and transmitted to the compressor mounting plate, and the attenuated vibration is attenuated by the vibration isolator II and transmitted to the base plate, the divided base plate The vibration transmitted to the motor is much smaller than the vibration of the compressor that is the vibration source. Further, since the vibrations doubly attenuated do not interfere with each other by the divided base plates, they are not amplified and cause the bottom plate to resonate, so that the noise can be suppressed low.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, (1) is a dish-shaped bottom plate, (2) is a left side panel standing upright on the bottom plate, and (3) is an L-shaped cross-section forming a rear panel part and a right side panel part. Of the left side panel (2) and the side panel (3) are arranged so as to cover the upper bent portions of the left side panel (2) and the side panel (3), and (5) is the left side panel (2), the side panel. (3) A front panel for covering an opening formed by assembling the top panel and the bottom plate (1).
(6) is a compressor for forming a refrigerant circuit, (7) is also a four-way valve, (8) is a non-use side heat exchanger, and (9) is an accumulator. Further, (16) is a pair of left and right base plates for fixing the compressor (6) and the accumulator (9), and the non-use side heat exchanger (8) is a cushioning material II.
It was placed via (19). Reference numeral (11) is a cushioning material I used when fixing the base plate (16) to the bottom plate (11). Further, (12) is a control box fixed to the side panel (3) and the water pipe mounting plate (13) of the non-use side heat exchanger (8).

FIG. 2 shows the details of mounting the compressor (6) and the accumulator (9) of the air conditioner according to the present invention. In the figure, (17) is a compressor mounting plate attached to the base plate (16) via a vibration isolator II (18), and the upper surface thereof is compressed via a vibration isolator I (14). The machine (6) is attached. Reference numeral (15) is a fixing column used for fixing the accumulator to the base plate (16).

In the air conditioner configured as described above, the compressor (6) includes the compressor mounting plate (17) via the vibration isolator I (14).
Vibrations of the compressor (6) fixed to the start-up, operation and stop are attenuated and transmitted to the compressor mounting plate (17). Further, since the compressor mounting plate (17) is fixed to the base plate (16) divided into two parts via the vibration isolator II (18), it is attenuated and transmitted to the compressor mounting plate (17). The vibration of the compressor (6) is so damped again that it is transmitted to the base plate (16) to form a so-called double vibration isolation structure.

Further, since the accumulator (9) is fixed to the base plate (16) through the fixing pillars (15), the low temperature of the accumulator (9), which is low during operation, directly affects the base plate (16). ) Is not transmitted to the base plate (16) to prevent dew condensation.

The base plate (16) is fixed to the bottom plate (1) through the cushioning material I (11) so that the damping vibration from the compressor (6) transmitted to the base plate (16) is not transmitted to the bottom plate (1). In addition to the structure, the structure is such that the low temperature of the accumulator (9) is cut off.

Therefore, the vibration of the compressor (6) is sufficiently damped by the above-mentioned double vibration isolation structure, and since the base plate (16) is also divided into two parts, the vibrations damped in the base plate interfere with each other. Was also resolved. Therefore, the amplified vibration is not generated due to the interference of the vibration, and it is possible to prevent the abnormal sound such as the resonance sound at the bottom plate (1) of the amplified vibration, which is a problem in the conventional air conditioner.

It should be noted that although the vibration-proof rubber is used as the form of the vibration-proof materials (14) and (18) in the above-described embodiment, it may be a vibration-proof spring.

[Effect of device]

This invention has a bottom plate in which four sides are bent, a left side panel, a rear panel, a right side panel, and a top panel fixed to the upper part of the panel. And a box body composed of a front panel easily fixed to the front surface, a pair of compressors housed in the box body, and a gas for the refrigerant that is provided corresponding to each of the compressors and returns to the compressor. In an air conditioner having an accumulator for separating a liquid, and a refrigerant supplied from the compressor, and a non-use side heat exchanger for exchanging heat with a fluid to be heat exchanged, the bottom plate is provided with a cushioning material. A pair of left and right base plates provided and a compressor mounting plate attached to each of the base plates via a vibration isolator II are provided, and the compression plate is compressed via the vibration isolator I to each compressor mounting plate. Since the machine is installed, the vibrations of the two compressors are dampened The transmitted, yet never vibration comrade to interfere with engagement connexion amplification. Further, the vibration propagating to the bottom plate can be reduced to a negligible level, and the generation of abnormal sound can be prevented.
