DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure requiring vibration proof and sound proof, and more particularly to a compressor unit used for an outdoor unit of an air conditioner, a refrigerator, a dehumidifier and the like. is there.

[0002] In general, vibration proof and sound proof are used in different meanings, but since sound is the vibration of air transmitted through the air, sound proof to prevent sound from being transmitted is included in the broad sense of vibration proof. It can be said that. Therefore, in the following, the term “vibration proof” is used to mean “sound proof”.

2. Description of the Related Art FIGS. 3 to 5 show examples of a conventional anti-vibration structure. Here, the vibration sources are the compressor 1 and the accumulator 2. A vibration isolating member is provided around the compressor 1 and the accumulator 2 so as to surround and cover them. The vibration isolating member in FIG. 3 is a felt 3a. The vibration isolating member may be a rubber sheet instead of the felt. Alternatively, a combination of a felt and a rubber sheet is also used. Alternatively, the vibration isolating member may be a metal plate 3b as shown in FIG. Alternatively, as shown in FIG. 5, there may be a case where a box-shaped cover 3c is formed by combining metal plates. By covering the vibration source with these types of vibration isolating members, the propagation of vibration and noise to the surroundings has been suppressed.

[0004]

In the vibration isolating structure including the above-described compressor 1, a gap 4 is formed between the compressor 1 and the vibration isolating member 2, so that an air layer is formed in the gap. Vibration energy generated from the compressor 1 propagates to the outside through this layer of air, causing adverse effects such as noise and vibration on the surroundings.

Accordingly, an object of the present invention is to provide a vibration damping structure and a compressor unit in which noise and vibration exerted on the outside are suppressed.

[0006]

In order to achieve the above object, in one aspect of the vibration isolating structure according to the present invention, a vibration source, a vibration isolating member arranged to cover the vibration source, and And a filling material that is a fluid or a solid having a higher viscosity coefficient than air filled in a space sandwiched between the vibration generation source and the vibration isolation member. By employing this configuration, there is no air layer between the vibration source and the vibration isolating member, so that the vibration generated from the vibration source cannot propagate through the air layer. On the other hand, since the filling material is filled, the vibration energy is absorbed and attenuated by the filling material, so that noise and vibration applied to the outside can be suppressed.

In order to achieve the above object, in one aspect of a compressor unit according to the present invention, a compressor, a vibration isolator surrounding the compressor, the compressor and the vibration isolator are provided. And a filling material which is a fluid or a solid having a higher viscosity coefficient than the air filled in the space sandwiched between the two. By employing this configuration, an air layer does not exist between the compressor and the vibration isolating member, so that vibration generated from the compressor cannot be transmitted through the air layer. On the other hand, since the filling material is filled, the vibration energy is absorbed and attenuated by the filling material, so that noise and vibration applied to the outside can be suppressed.

[0008] Preferably, in the above invention, the filling material is substantially composed of any one material selected from the group consisting of a foaming heat insulating material, a viscous fluid, a rubber material, cement, and water. By adopting this configuration, injection or molding as a filling material is easy, and vibration can be efficiently attenuated.

In order to achieve the above object, in another aspect of the vibration isolating structure according to the present invention, a vibration generating source, a vibration isolating member arranged so as to surround the vibration generating source, the vibration generating source and the vibration generating source, The space sandwiched between the vibration isolating members is substantially vacuum. By employing this configuration, the space between the vibration source and the vibration isolating member is substantially vacuumed, and there is no air layer. Therefore, the vibration generated from the vibration source cannot be propagated. Therefore, noise and vibration applied to the outside can be suppressed.

In order to achieve the above object, another aspect of the compressor unit according to the present invention includes a compressor, an accumulator, and a vibration isolator arranged to surround the compressor and the accumulator. The space between the compressor and the vibration isolator is substantially vacuum. By employing this configuration, the space between the compressor and the vibration isolating member is substantially vacuumed, and there is no air layer, so that the vibration generated from the compressor cannot be propagated. Therefore, noise and vibration applied to the outside can be suppressed.

(Embodiment 1) (Structure) FIG. 1 shows a compressor unit according to Embodiment 1 of the present invention. In this compressor unit, a felt 3a is wound as a vibration isolating member around a vibration source composed of the compressor 1 and the accumulator 2. The vibration isolating member may be a rubber sheet instead of the felt. Alternatively, a combination of a felt and a rubber sheet may be used. Alternatively, the vibration isolating member may be a metal plate 3b as shown in FIG. Alternatively, although not shown, a box-shaped cover configured by combining metal plates may be used. These vibration damping members have a structure for suppressing vibration and noise of the vibration source.

However, in the vibration isolating structure according to the present embodiment, not only the vibration isolating member is provided but also the gap between the compressor 1 and the accumulator 2 as the vibration generating source and the vibration isolating member is filled. As the substance 5, a foaming resin is filled and substantially filled. As the filling substance 5, in addition to the foamable resin, a viscous fluid, a rubber material, cement,
It may be water or the like.

(Operation / Effect) Since the gap between the vibration source and the vibration isolating member is filled and substantially filled with the filling substance, it is not a mere air layer as in the conventional case. Vibrations generated from the source propagate to the packing material instead of to the air layer. However, the filling material is a foaming resin, a viscous fluid, a rubber material, cement, water, or the like, and has a greater effect of absorbing vibration energy and attenuating vibration than air. Therefore, the vibration does not propagate to the outside with the same magnitude, and a compressor unit in which noise and vibration exerted on the outside can be suppressed.

The filling material is preferably the above-mentioned one, but is not limited to the above-mentioned one, and may be any fluid or solid having a higher viscosity coefficient than air.

The vibration damping structure in which the filling material is filled between the vibration source and the surrounding vibration damping member as described above is not limited to the application to the compressor unit, but is generally widely used for vibration damping purposes. The effect can be obtained.

Embodiment 2 (Configuration) A compressor unit according to Embodiment 2 of the present invention will be described. Basically, it is the same as the compressor unit in the first embodiment, but instead of filling the gap between the vibration source and the vibration isolating member with the filling material 5, the gap is substantially vacuumed.

(Operation / Effect) Since the gap between the vibration source and the vibration isolating member is substantially vacuum, there is no air layer that has conventionally propagated the vibration generated from the vibration source. Since there is no air layer, the propagation of vibration can be greatly suppressed.

The above-described vibration isolating structure in which the space between the vibration generating source and the surrounding vibration isolating member is substantially vacuum is not limited to application to the compressor unit, but is generally widely used for the purpose of vibration isolation. The effect can be achieved.

The above embodiment disclosed this time is illustrative in all aspects and is not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and includes any modifications within the scope and meaning equivalent to the terms of the claims.

[0020]

According to the present invention, no air layer is present between the vibration source and the vibration isolating member, so that the vibration generated from the vibration source cannot propagate through the air layer. . As a result, external noise and vibration can be suppressed.
