[Industrial applications]

  The present invention is an anti-vibration support device for a compressor for suppressing noise generated during operation of the compressor. Regarding the table

[0002]

[Prior art]

  Compressors are essential for air conditioners, electric refrigerators, etc. It is a part. However, since this compressor is a kind of rotating equipment, it does not vibrate or It is the source of sound. Therefore, in air conditioners and electric refrigerators, the compressor and its pressure Elastic support is provided via rubber or spring between the bases where the compressor is placed, This absorbs the vibration from the compressor and suppresses the generation of noise. It

[Problems to be solved by the device]

  By the way, compressors used in air conditioners and the like are roughly classified as shown in FIG. A structure called a reciprocating type and a rotary type as shown in FIG. However, in recent years, the rotary type has gained popularity due to its size and ease of control. is occupying. In the reciprocating type, the compression device 21 and the motor 22 are integrally connected. They remain suspended in the housing 23 via the spring 24. Vibration from the compressor 21 etc. is absorbed to some extent inside the housing 23 The vibration transmitted from the leg 25 to the base 26 is updated by the vibration-proof member 27 interposed between the two. The rotary type shown in FIG. 5 is a compression device. 21 and the stator 22a of the motor 22 are directly fixed to the housing 23, respectively. As the reciprocating type cannot absorb the vibration in the housing 23, the compression device 21 Vibration from the motor and the motor 22 is generated by the vibration isolation member 27 interposed between the mounting leg 25 and the base 26. Vibrations that are not absorbed by the vibration isolator 27 are absorbed only by the base 26 The noise is transmitted and expanded from the air conditioner to the box of the air conditioner. Therefore, this vibration is received If you try to absorb it in the housing 23 in the same way as the formula b, the internal structure for that Is complicated, and the size of the housing 23 will be increased accordingly, and the cost will increase. Problem occurs. Therefore, in the present invention, these problems should be taken into consideration. The anti-vibration support device of the compressor that takes measures that can suppress the noise at low cost. It is intended to be provided.

[0004]

[Means for Solving the Problems]

  The present invention has been made to solve the above problems, and a compressor is installed on the base. In the case of elastically supporting the compressor, the compressor is attached to the mounting plate via the first vibration isolation member. Attach it and attach the same mounting plate to the base via the second anti-vibration member. did.

[0005]

[Action]

  With the above configuration, the vibration transmitted from the compressor to the base is first considered as the compressor. The first anti-vibration member absorbs the first anti-vibration member which is interposed between the attached plates. The vibration that could not be completely absorbed is further absorbed by the second anti-vibration section interposed between the mounting plate and the base. Since it is absorbed by the material, the noise of the air conditioner etc. due to the compressor is reduced. can do.

【Example】

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 shows the air conditioner room 1 is a base, 2 is a box body, 3 is a base 1 and a box body 2. A partition plate that divides the inside of the main body into a heat exchanger room 4 and a machine room 5. An outdoor heat exchanger 6 and a heat dissipating propeller fan 7 are arranged in Is provided with a control device 8 on the upper part, and is controlled by the control device 8 on the lower base 1. A compressor 9 is installed.

[0007]   By the way, the compressor 9 is mounted on the base 1 by the vibration-proof support device A as shown in FIG. It is attached. The anti-vibration support device A will be described below. The compressor 9 There is a mounting leg 11 that opens on three sides at the bottom of the housing 10 that constitutes the main body of Locking holes for locking the anti-vibration member 12 are provided at the tips of the mounting legs 11. Has been. The vibration isolator 12 may be, for example, a ring-shaped spring, but in the present embodiment, Elastic rubber is used and its shape is roughly cylindrical. 13 is a compressor 9 Is a mounting plate for mounting, the shape of which is shown in FIGS. 3 (A) and 3 (B). It has a disk shape, and the disk has a vibration isolating member 12 that is locked to the mounting leg 11. Three bolts 14 corresponding to the holes are erected. These bolts 14 are The nut is tightened at the end after it is inserted into the hole.

[0008]   In addition to the three bolts 14, the mounting plate 13 has locking holes for locking the anti-vibration member 15. Are formed at three locations near the outer circumference. Anti-vibration locking in these three locking holes The member 15 has the same shape as the vibration damping member 12 described above, and the base 1 has Three bolts 16 matched with the vibration isolating member 15 are erected. These bolts After being inserted into the vibration isolator 15, the tip of the 16 is tightened with a nut. This With such a configuration, the compressor 9 is doubly elastically supported, so that the lower vibration isolator 15 Can absorb the vibration from the compressor 9 that could not be completely absorbed by the upper vibration isolator 12. It can be done.

[0009]   3A and 3B show the difference in the size of the mounting plate 13 and the vibration-damping member 15, respectively. It shows the relation of the mounting position, and the space in the machine room where the compressor 9 is placed If there is, the diameter of the mounting plate 13 is increased as shown in FIG. Vibration damping with a viscoelastic resin sandwiched between ordinary steel plates and steel plates. If it is replaced with a steel plate, the shear energy of the viscoelastic resin causes the vibration energy to Since it is converted into energy, the vibration damping effect is enhanced and the noise is further prevented.

[0010]

[Effect of device]

  If the outdoor unit is as described above, it is transmitted from the compressor to the base. The generated vibration is first caused by the vibration damping member on the top that is interposed between the mounting leg of the compressor and the mounting plate. Vibrations that are not absorbed by the vibration-damping member above the mounting plate. Because it is absorbed by the lower vibration-isolating member interposed between the base and the base, it is caused by the compressor. The outdoor unit is less noisy. Also, the results can be obtained with a small number of components. Therefore, it is more cost effective than modifying the compressor itself.
