[0002]
[Prior art]
Conventionally, a plurality of mounting legs provided around a lower portion of a compressor of a cooling device are mounted on a mounting base via a vibration-isolating rubber, and a compression bolt attached to the mounting base with a mounting bolt penetrating a central portion of the vibration-isolating rubber. There is a support device for the machine (for example, see Patent Document 1).
[0003]
Patent Document 1 discloses that the prior art is disclosed as FIGS. 4 to 6 and that the invention of Patent Document 1 solves the problem of the technique. In FIG. 4, the vibration of the compressor is absorbed by a support made of an elastic material such as rubber having a hollow inside, but the inverter type compressor cannot cope with a wide range of rotation speed. It was stated that there was a problem. 5 is provided with vibration isolating rubbers on the upper and lower sides and absorbs the vibration of the compressor via a metal coil spring between them. However, there is a problem that the number of parts increases and it takes time to assemble. It is described. 6 is a bellows-like support, which has a vibration damping effect against vertical vibrations, but can cope with a wide range of compressor vibrations against horizontal vibrations. There is no description.
[0004]
Therefore, it is the invention of Patent Document 1 that solved these problems. The invention of Patent Literature 1 is a support formed of a rubber-based elastic body. An upper portion of the support is provided with an annular holding portion for holding a periphery of a mounting hole of a mounting leg of the compressor. The body portion is constituted by a body portion that elastically supports between the bases, and the outer surface of the body portion is formed into a spiral strip. Although the effect described by this configuration may be expected, in this support structure, the compressor is supported by a rubber-based elastic body that is long in the vertical direction. It is conceivable that the refrigerant pipe connected to the compressor may be damaged such as bent or bent.
