Description

[Detailed description of the invention] This invention relates to a support device for an electric compressor, and in particular to a vibration-proof support device for a rotary electric compressor used in room coolers, etc. The purpose is to improve assembly work and reduce costs. It is said that

As shown in Fig. 4, the conventional anti-vibration support device has a sealed container 1.
The foot A is welded to the bottom of the foot A, and the upper part of the vibration isolating rubber C is inserted into the plurality of vibration isolating comb support holes drilled in the foot A, and the vibration isolating rubber is used in the machine room of a unit such as a room cooler. It had a structure in which it was placed and held in a vibration-proof rubber holding plate d that was welded to the bottom substrate e.

Because of this structure, in the past, it was troublesome to attach the anti-vibration rubber C to each leg a one by one.After attachment, the sealed container with the anti-vibration rubber holding plate dK on the unit board was placed on the upper support bracket 12.
If the upper support pin 11 is tilted (see Fig. 1) before it is supported, the vibration isolating rubber may slip out of the vibration isolating rubber support hole of the leg a, and there is a risk that it may be assembled without being noticed.

This invention was an attempt to eliminate the above-mentioned drawbacks and also to improve the cost.In the electric compressor support device according to this invention, the closed container housing the electric element and the compression element is separated into two upper and lower parts. This is a support device for the lower side of an electric compressor that is buffer-supported at two or more points, including a lower support pin that protrudes near the center of the bottom of a closed container, and a flanged hole provided in the bottom board of the machine room of a unit such as a room cooler. a central boss part that is fitted into the flange of the flanged hole and has concentrically a ring groove and a hole into which the lower support pin is inserted; It is characterized by being composed of a vibration isolating rubber integrally formed with two vibration isolating parts.

The structure of this invention will be explained with reference to the embodiment shown underground. As shown in FIG. A rounded lower support pin 2, a flanged hole 8 drilled in a purling shape in the bottom board 7 of the machine room of a unit such as a room cooler, and a 7-lunge 9 of this hole 8.
A ring groove 5 to be fitted into the hole 4 into which the lower support pin 2 is inserted
and a vibration isolating rubber 3 having a central boss portion 6 formed with.

The vibration isolating rubber 3 has a plurality of vibration isolating parts 10 formed integrally with this boss part instead of one boss part 6, and this vibration isolating part 10
ri is located between the substrate 7 and the sealed container 1 in place of the boss portion 6 so as to elastically support the sealed container 1.

The upper part of the closed container 1 is supported by an upper support pin 11 and a support fitting 12 that holds the upper support pin 11.

Reference numeral 13 denotes a discharge connecting pipe for sending refrigerant gas discharged from the closed container 1 to the unit side, and 14v'i a suction connecting pipe for returning the refrigerant gas returning from the unit side to the closed container IIL.

The supporting device of this invention works as follows.

The lateral vibrations of the sealed container, which often occur during transportation, are mainly damped by the lower support pin 2 inserted into the hole 4 coming into contact with the vibration-proof rubber wall around the hole 4, and the electric compressor Vertical vibrations that tend to occur during operation are prevented by the vibration isolator 10 that elastically supports the closed container.

In addition, the vibration isolating rubber 3ri is rotatably supported by the cylindrical flange 9, and the vibration isolating part 10 is always placed in a symmetrical position with respect to the hole 4. The function of fixing the position of the vibration isolator 10, such as the holding plate d, and the member for this function are completely unnecessary.

According to this invention, it is very easy to attach the vibration isolating rubber, and there is no need to fix the position of the vibration isolator, so the structure is simplified and the cost can be significantly reduced.

Furthermore, since there is no longer a need for the feet a that were conventionally required to attach anti-vibration rubber to a sealed container, the height of the sealed container can be lowered by H shown in Figure 4, making space in the machine room more effective. Available.
