Abstract

PURPOSE:To properly absorb the vibrations at the time of the start, stop, and operation respectively by vertically overlapping cushion rubbers having different spring constants respectively to form multiple elastic support members elastically supporting a sealed container via a fitting leg into a double structure. CONSTITUTION:A horizontal rotary compressor 11 is fitted with a fitting leg 14 on the outer wall of a sealed container 13 stored with an electric compression mechanism section 12 inside. The sealed container 13 is elastically supported by multiple elastic support members 15A, 15B via the fitting leg 14. Cushion rubbers or springs having different spring constants respectively are vertically overlapped to form the elastic support members 15A, 15B into a double structure 15. The vibration at the time of a start is absorbed by the elastic support member 15B having a large spring constant on the R-side, and the vibration at the time of a stop is absorbed by the elastic support member 15B having a large spring constant on the L-side. The vibration at the time of operation is absorbed by the elastic support members 15A having a small spring constant.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting device for a horizontal rotary compressor, and more particularly to a supporting device for a hermetic horizontal rotary compressor.

[0002]

2A and 2B are a front view and a side view of a conventional supporting device for a horizontal rotary compressor. In FIG. 2, 1 is a horizontal rotary compressor, 2 is an electric compression mechanism, 3 is a closed container, 4 is a mounting leg, and 5 is an elastic support member. The support device for the horizontal rotary compressor 1 shown in FIG. And a plurality of elastic supporting members 5 that support the above. In the horizontal rotary compressor shown in FIG. 2, a cushion rubber having the same spring constant is used for the elastic supporting member 5 of the supporting device.

[0003]

However, the conventional supporting device for a horizontal rotary compressor shown in FIG. 2 is effective in suppressing vibration during operation when an elastic supporting member having a small spring constant is used. However, at the time of starting, a large vibration is suddenly generated in the direction opposite to the rotation direction of the electric compression mechanism section 2, and
At the time of stop, a large vibration is generated suddenly in the same direction as the rotation direction of the electric compression mechanism unit 2, and therefore the vibration cannot be suppressed by the elastic support member having a small spring constant. There was a problem of bringing. On the other hand, when an elastic supporting member having a large spring constant is used, vibration at the time of starting and stopping can be suppressed, but there is a problem that the vibration at the time of operation is easily transmitted to the unit pipe.

[0004]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a mounting leg to be mounted on the outer wall of a hermetically sealed container having an electric compression mechanism inside, and the sealing leg via the mounting leg. In a supporting device for a horizontal rotary compressor including a plurality of elastic supporting members that elastically support a container, the plurality of elastic supporting members have a double structure in which cushion rubbers or springs having different spring constants are vertically stacked. The present invention is intended to provide a support device for a horizontal rotary compressor formed in the above. In the plurality of elastic support members having a double structure, it is preferable that the spring constant of the elastic support member attached to the mounting leg be smaller than the spring constant of the elastic support member below the elastic support member.

[0005]

As the elastic support member, two cushion rubbers having different spring constants or springs having a double structure formed by stacking the springs vertically are used. Therefore, each vibration during start, stop and operation of the horizontal rotary compressor is prevented. Always reduce.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a supporting device for a horizontal rotary compressor according to the present invention will be described below with reference to FIGS. 1A and 1B are a front view and a side view of a supporting device for a horizontal rotary compressor according to the present invention.
In FIG. 1, 11 is a horizontal rotary compressor, 12 is an electric compression mechanism part, 13 is a closed container, 14 is a mounting leg, and 15 is a double-structure elastic supporting member. The support device for a horizontal rotary compressor shown in FIG. In the present embodiment, cushion rubber is used for the plurality of elastic support members 15, and 15A is a cushion rubber A portion and 15B is a cushion rubber B portion. A cushion rubber having a small spring constant is used for the cushion rubber A portion 15A, and a cushion rubber having a large spring constant is used for the cushion rubber B portion 15B. A spring may be used as the elastic support member 15 instead of the cushion rubber. The support device for the horizontal rotary compressor according to the present invention uses the double-structure cushion rubber 12, so that the vibration mainly occurs at the cushion rubber B portion 12B having a large spring constant on the R side in FIG. Absorb and stop when Figure 1
(A) Cushion rubber with large spring constant on L side B part 1
Vibration can be mainly absorbed by 5B. Further, during operation, vibration can be mainly absorbed by the cushion rubber A portion 15A of the small spring portion.

[0007]

Since the supporting device for the horizontal rotary compressor according to the present invention is constructed by using the cushion rubber having the double structure having different spring constants as described above, each vibration at the time of starting, operating and stopping. Can always be absorbed properly, and the fatigue of the unit piping can be reduced.
