Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1 and Fig. 2, the air-conditioner outdoor unit that the utility model first embodiment provides comprises shell, is positioned at the noise reduction mounting structure of the compressor of described shell, the blower fan being positioned at described shell and compressor, and described shell comprises chassis 10.The structure except chassis 10 of its housing is not shown, and compressor and blower fan are all not shown, but compressor, blower fan and shell are compressor, blower fan and shell that common air-conditioner outdoor unit uses, will not illustrate at this, description that also will not be too much.
The noise reduction mounting structure of described compressor comprises and being arranged on described chassis 10 and fixture 20 in order to be connected with compressor fixing feet, described fixture 20 comprises the body of rod 21 and is connected to the cap body 22 of an end of the described body of rod 21, the noise reduction mounting structure of described compressor also comprises the elastic footrest (not shown) be sheathed on the described body of rod 21, the described cap body 22 of described fixture 20 is positioned at the bottom on described chassis 10, the described body of rod 21 is upward through described chassis 10, pad between described elastic footrest and described cap body 22 and be provided with pad 30, the intrinsic frequency of described pad 30 is at least 3000 hertz, and the upright projection of described elastic footrest on described pad 30 is within the outer rim of described pad 30.At this, elastic footrest does not also illustrate in the drawings, but this elastic footrest is the elastic footrest that usual indoor apparatus of air conditioner uses, and does not add auspicious stating at this.
The air-conditioner outdoor unit of the utility model first embodiment is roughly the same with common air-conditioner outdoor unit, and its difference is only that air-conditioner outdoor unit that the utility model first embodiment provides has the noise reduction mounting structure of compressor.
Because air-conditioner outdoor unit is provided with the noise reduction mounting structure of compressor, the noise reduction mounting structure of this compressor pads and is provided with pad 30 between elastic footrest and cap body 22, ensure that the intrinsic frequency of pad 30 is at least 3000 hertz, and ensure that the upright projection of elastic footrest on pad 30 is within the outer rim of pad 30, the noise of whole air-conditioner outdoor unit can be reduced, compared with common air-conditioner outdoor unit, the level of noise of the air-conditioner outdoor unit that the utility model first embodiment provides at least reduces 1-2dB (A), reduce the nameplate noise figure of air-conditioner outdoor unit, improve product competitiveness commercially, in the develop rapidly of air-conditioning now, consumer all has strict requirement to the indices of product, the noise of the air-conditioner outdoor unit that the utility model first embodiment provides obviously decreases, more consumer selects such air-conditioner outdoor unit.Meanwhile, the problem such as unreliable reducing the bad and damping glue of product appearance that noise brings on chassis 10 by increasing damping material is also avoided.
Please refer to Fig. 3, the transverse axis of Fig. 3 represents the operating frequency of compressor, the longitudinal axis represents the level of noise of whole air-conditioner outdoor unit, broken line A in figure represents the level of noise of the whole indoor apparatus of air conditioner under the different operating frequencys of the compressor recorded after air-conditioner outdoor unit adds the noise reduction mounting structure of compressor, the level of noise of the whole indoor apparatus of air conditioner under the different operating frequencys of the compressor that the broken line B in figure records after representing the noise reduction mounting structure of air-conditioner outdoor unit without compressor.Broken line A is compared with broken line B, and under each operating frequency of compressor, the level of noise that broken line A is more corresponding than broken line B differs at least 1-2 decibel (dB (A)), and larger noise difference is 2-4 decibel.
The third-octave figure of indoor apparatus of air conditioner (i.e. the utility model first embodiment provide indoor apparatus of air conditioner) when a certain operating frequency of compressor of the noise reduction mounting structure with compressor is provided please refer to Fig. 4 and Fig. 5, Fig. 4.Fig. 5 shows the third-octave figure of indoor apparatus of air conditioner when the identical operating frequency of compressor of the noise reduction mounting structure without compressor.As can be seen from two figure, in the frequency range of 800 ~ 1200Hz, level of noise obviously reduces, particularly, the indoor apparatus of air conditioner that the utility model provides at least reduces 1-2 decibel in the frequency range of 800 ~ 1200Hz, especially, under the frequency of 1000Hz, the indoor apparatus of air conditioner that the utility model provides decreases 4-5 decibel.Can find out in Figure 5, level of noise under the frequency of 1000Hz is maximum, and indoor apparatus of air conditioner of the present utility model have employed " pad between described elastic footrest and described cap body 22 and be provided with pad 30; intrinsic frequency of described pad 30 is at least 3000 hertz; and the upright projection of described elastic footrest on described pad 30 is within the outer rim of described pad 30 " such technical scheme, just in order to mainly reduce the level of noise in the frequency range of 800 ~ 1200Hz.More preferably, the intrinsic frequency of pad 30 can be more than 4000 hertz, and its noise reduces more obvious.In figures 4 and 5, the noise contrast of indoor apparatus of air conditioner under the operating frequency of compressor 90Hz of the indoor apparatus of air conditioner showing the noise reduction mounting structure with compressor and the noise reduction mounting structure without compressor, research finds, the noise contrast of the two kind indoor apparatus of air conditioner of compressor under other operating frequency, the compressor of same display indoor apparatus of air conditioner of the present utility model obviously reduces in the frequency range level of noise of 800 ~ 1200Hz, same reduction 1-2 decibel.Particularly the level of noise of compressor under the frequency of 1000Hz reduces ground more obviously, decreases 4-5 decibel.
Please refer to Fig. 2, in the present embodiment, described pad 30 is between described elastic footrest and the inner surface on described chassis 10.Described pad 30 is that the outer rim of annular or described pad 30 is square and inner edge is rounded.No matter what shape pad 30 is, if ensure the intrinsic frequency of described pad 30 be at least 3000 hertz and the upright projection of described elastic footrest on described pad 30 within the outer rim of described pad 30.This pad 30 as one independently parts be arranged between the inner surface on elastic footrest and chassis 10.
Particularly, described pad 30 is annular, and the thickness range of described pad 30 is 0.5mm-5mm, and the outside diameter scope of described pad 30 is 25mm-60mm.When pad 30 is annular, the thickness of pad 30 is within the scope of 0.5mm-5mm, and the outside diameter of pad 30 is within the scope of 25mm-60mm, and the intrinsic frequency that all can reach pad 30 is at least 3000 hertz.Such as, the thickness of circular gasket 30 is 2mm, and the outside diameter of pad 30 is that the intrinsic frequency that 50mm can reach pad 30 is at least 3000 hertz; The thickness of circular gasket 30 is 2mm, the outside diameter of pad 30 is that the intrinsic frequency that 40mm can reach pad 30 is at least 3000 hertz, even the intrinsic frequency of pad 30 is at more than 4000Hz, effectively can promote the local intrinsic frequency of compressor fixture 20 installation site on chassis 10, avoid the resonance mode of 1000Hz, reduce 1000Hz noise, adopt this scheme noise reduction to reach 1 ~ 2dBA, the level that the noise at 1000Hz place cannot not be reduced to outstandingly.。
