Description

[Detailed description of the invention] A. Industrial application field This invention relates to a support device for a compressor incorporated in an air conditioner, refrigerator, etc.

B. Prior Art As a support device for preventing vibrations of a compressor from being transmitted to a circuit board, for example, as explained in Japanese Utility Model Publication No. 53-30722, a mounting hole provided in a support leg of a compressor is used as a support device to prevent vibrations of a compressor from being transmitted to a board. It has a structure that fits into the annular groove of the swinging rubber.

In such a structure, this fitting work is troublesome, so as proposed in the above-mentioned publication, the neck of the vibration isolating rubber is improved so that the neck can be easily inserted into the mounting hole of the support leg.

C. Problems to be Solved by the Invention The improved structure proposed in the above-mentioned publication had a problem in that the cost of the mold for molding the anti-vibration rubber was high because the neck part had a complicated shape. Moreover, the compressor shakes greatly when it starts and stops, and this impact force is applied to the grooves in the neck, causing cracks in the grooves.

The present invention solves these problems and provides a compressor support device that is inexpensive and highly durable.

D. Means for Solving the Problems This proposal consists of a support rod to which a substrate is fixed, a vibration-proof rubber which has a through hole through which the support rod passes and is placed on the substrate, and a vibration-proof rubber provided on the compressor. A mounting leg that is placed on the rubber is provided, and the mounting leg is provided with a through hole through which the support rod passes, and a regulating piece that comes into contact with the side surface of the vibration isolating rubber to prevent movement in the outer circumferential direction of the compressor, The gap between the through hole and the support rod is set to be larger than the gap between the through hole and the support rod.

E. Function To assemble the support device, first fix the support rod to the board with it facing upward, then fit the anti-vibration rubber onto the support rod from above and place it on the board. The process is completed by placing the mounting leg on the vibration isolating rubber and joining the regulating piece of the mounting leg to the upper side surface of the vibration isolating rubber.

When the compressor is in operation, especially when the compressor starts and stops shaking greatly in the outer circumferential direction, this shaking is blocked by the regulating piece of the mounting leg that is connected to the upper side of the vibration isolating rubber, and the compressor is connected to the compressor. The refrigerant pipes installed will not break. In addition, since small vibrations generated during operation of the compressor are absorbed by the vibration-proof rubber which is not in contact with the support rod, almost no vibrations are transmitted to the substrate, thereby suppressing the generation of noise.

F. Embodiment Figure 1 is a longitudinal sectional view of a support device showing an embodiment of the present invention, Figure 2 is an exploded perspective view of the main parts of this support device, and Figure 3 is a plan view of a compressor equipped with this support device. ,
1 is a substrate corresponding to the bottom plate of an air conditioner; 2 is a support rod consisting of a bolt that penetrates the substrate 1 from the bottom to the top and has a head 3 fixed to the substrate 1 by welding; 4 is a gap 5 between the support rod 2; vibration isolating rubber which is fitted and placed on the substrate 1; 6 is a mounting leg which is provided at the bottom of the rotary compressor 7 and extends outward and is placed on the vibration isolating rubber 4; 8a is a nut with a washer 8b that is screwed onto the upper end of the support rod 2.

Three mounting legs 6 are provided as shown in FIG. 3, and each mounting leg 6 has a through hole 10 that fits into the support rod 2 with a gap 9 larger than the above-mentioned gap 5. A pair of regulating pieces 12 are provided which are joined to the upper side surface 11 of the vibration isolating rubber 4 and prevent movement of the compressor 7 in the outer circumferential direction.

The structure is as described above, and the order of assembling the support device is to first fix the three support rods 2 to the substrate 1 as described above, and then connect the through holes 13 of the anti-vibration rubber 4 to the support rods 2 in the upward direction. Three anti-vibration rubbers 4 are placed on the substrate 1 by twisting them together. After that, the through holes 10 of the three mounting legs 6 previously welded to the compressor 7
While aligning the support rod 2 and the support rod 2, place the mounting leg 6 on the vibration isolating rubber 4, and place the regulating piece 12 on the vibration isolating rubber 4.
After joining with the upper side surface 11 of the support rod 2, the nut 8a with washer 8b is screwed onto the upper end of the support rod 2, and the assembly is completed.

When the compressor 7 is in operation, especially when the compressor 7 is started and stopped in a large swing in the outer circumferential direction (in the direction of the solid line arrow shown in FIG. 3), this swing is connected to the upper side surface 11 of the vibration isolating rubber 4. Since this is prevented by the regulating piece 12 of the mounting leg 6, the refrigerant pipes connected to the compressor 7, such as the refrigerant discharge pipe 14 and the refrigerant suction pipe 15, will not be bent due to excessive force. Furthermore, small vibrations in the lateral and vertical directions that occur during the operation of the compressor 7 are absorbed by the vibration isolating rubber 4 that is not in contact with the support rod 2, and are hardly transmitted to the substrate 1.

In the above embodiment, if the base plate 1 is formed into a truncated conical shape and the stepped portion 18 that engages with the arcuate edge 17 of the seat press portion 16 is integrally formed on the bottom surface of the vibration isolating rubber 4. Since the vibration isolating rubber 4 does not move on the substrate 1 due to the above-mentioned shaking that occurs when the compressor 7 starts and stops, bending of the refrigerant piping is more reliably prevented. 1
This will improve the strength of the

Further, the nut 8a with washer 8b is required when the air conditioner is packaged and transported.During transportation, the mounting leg 6 is removed by pushing the push-up tool 20 upward through the opening 19 of the board 1 to push up the bottom of the compressor 7.
is pressed against the washer 8b, so the compressor 7 is in a fixed state. In this state, the anti-vibration rubber 4 is held between the pair of regulating pieces 12 and lifted upward together with the mounting legs 6, so it will not shift its position, and in the unlikely event that the anti-vibration rubber 4 is not lifted and is placed on the board 1. Even if the vibration isolating rubber 4 remains, the upper part of the vibration isolating rubber 4 is housed between the pair of regulating pieces 12, so that it will not be displaced.

G. Effects of the invention According to the present invention, the compressor can be supported by the simple work of placing the mounting legs of the compressor on the vibration isolating rubber, so the workability is good, and the vibration isolating rubber is attached to the mounting legs. The mold cost for the anti-vibration rubber can be reduced because a simple shape that matches the shape of the rubber is sufficient.

In addition, when the compressor starts and stops shaking greatly in the outer circumferential direction, the regulating piece of the mounting leg is in surface contact with the upper side surface of the vibration isolating rubber, preventing the vibration from shaking, so there is a risk of cracks occurring in the vibration isolating rubber. With no,
Since the shaking of the compressor is quickly stopped, there is no risk of the refrigerant pipe connected to the compressor breaking.
Furthermore, since the gap between the through hole of the mounting leg and the support rod is set larger than the gap between the vibration isolating rubber and the support rod, there is no possibility that the mounting leg and the support rod will come into contact and generate metallic sounds.

Further, small vibrations generated during operation of the compressor are absorbed by the vibration-proof rubber which is not in contact with the support rod, so that almost no vibrations are transmitted to the substrate, and noise can be reduced.
