The points different from FIG. 8 will be mainly described.

That is, the difference of the present embodiment from the conventional one is that the vibration damping support mechanism on the upper side of the hermetic electric compressor is provided on the side portion of the pressure vessel.

For this reason, in this embodiment, one end of the substantially L-shaped compressor support fitting 10 is fixed to one side piece 9a of the suction muffler supporting member 9 whose base is fixed to the side surface of the pressure vessel 1, and the other end is directed upward. A cylindrical vibration-proof rubber 11 is attached to the upwardly protruding end portion by engaging with a deep groove hole 11a formed in the central portion thereof. 12 is the unit side plate
13 is a unit mounting member arranged horizontally between the vibration isolating rubber 11 and the vibration isolating rubber 11, one end of which is fixed to the unit side plate 13, and the other end of which is a circular hole into which the vibration isolating rubber 11 is tightly fitted.
14 are drilled.

The vibration isolating support mechanism on the lower side of the pressure vessel 1 is a unit in which the leg member 3, the vibration isolating rubbers 5 and 5 attached thereto, and the antivibration rubbers 5 and 5 are inserted as in the case of FIG. It is composed of the bottom plate 7.

In the supporting device configured as described above, when the pressure vessel 1 of the electric compressor is vibration-isolated and supported, the lower side thereof is supported by the unit bottom plate 7 by the vibration-insulating rubbers 5 and 5, and the support metal fitting 10 is attached. The attached anti-vibration rubber 11 is press-fitted into the circular hole 14 of the unit mounting member 12 to support the upper side of the pressure vessel 1.

In this embodiment, the vibration damping support on the upper side of the electric compressor body is performed on the side portion of the pressure vessel 1, so that the distance between the top of the pressure vessel 1 and the unit can be narrowed. The space occupied in the vertical direction of the electric compressor can be reduced.

FIG. 5 shows a second embodiment of the supporting device of the present invention. In this embodiment, a groove 15 is formed in a ring shape on the outer periphery of a columnar vibration isolating rubber 11 attached to the upper end of the support fitting 10, and the ring groove 15 is engaged with the peripheral edge of the hole 14 of the unit mounting member 12. By doing so, the upper side of the pressure vessel 1 is supported.

With such a support system, the vibration-proof support of the electric compressor is stable not only in the horizontal direction but also in the vertical direction.

6 and 7 show a third embodiment of the supporting device of the present invention. In this embodiment, the same reference numerals as those in FIG. 2 indicate the same or corresponding portions, and the difference from FIG. 2 is that the compressor support metal fitting 10A is integrally formed from the molded member of the suction muffler support 9. is there. That is, the tongue piece 16 having a desired length is integrally provided at the lower end of the one side piece 9a of the suction muffler support 9,
By bending the tongue piece 16 upward in a U shape, the support fitting 10
A is formed, and a vibration-proof rubber 11 is attached to the upper end of the support metal fitting 10A, and the vibration-proof rubber 11 is fitted into the hole 14 of the unit mounting member 12 to support the upper side of the electric compressor with vibration-proof support. .

In this embodiment, in addition to the same effects as those of the first embodiment, the number of parts of the supporting device can be reduced and the cost can be reduced.

[Effect of device]

As described above, according to the present invention, the suction muffler support having the base fixed to the side surface of the pressure vessel of the electric compressor and the side extending from the base at right angles to support the suction muffler, One end of the suction muffler is fixed to the side of the muffler support, and the other end of the compressor support fitting projects upward, a cylindrical vibration-proof rubber attached to the end of this support fitting, and the outer circumference of this vibration-proof rubber. Since the unit mounting member that has the circular hole that engages and that connects this anti-vibration rubber to the unit side plate is provided, the space between the top of the pressure vessel and the unit facing it can be narrowed, The occupying space of the electric compressor can be reduced, and these compressor support metal fittings, anti-vibration rubber and unit mounting members can be sucked in at the side between the pressure vessel and the suction muffler of the electric compressor. A vibration proof effect can be obtained with a simple structure that is integrated with the fuller support, and a columnar vibration proof rubber attached to the tip of the compressor support metal fitting protruding upward and the circular shape of the unit mounting member. By virtue of the engagement with the holes, it is possible to accurately obtain the front, rear, left, and right anti-vibration effects in the horizontal direction. There is an effect that the hermetic electric compressor can be properly and reliably supported.
