Embodiment
It should be noted that, in the situation that not conflicting, embodiment and the feature in embodiment in the application can combine mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Fig. 2 shows according to the schematic diagram of embodiments of the invention one, as can be seen from the figure, compressor in the present embodiment comprises the first cylinder, the first air intake passage 11 and the first resonant cavity 21, wherein, the first cylinder has the first cylinder body, on the first cylinder body, have between the first air intake passage 11, the first resonant cavities 21 and the first air intake passage 11 and be connected by the first intercommunicating pore 22.According to the compressor of the present embodiment, the first resonant cavity 21 is communicated with the first air intake passage 11, when compressor carries out aspiratory action, air-breathingly in the first air intake passage 11, flow, when air-breathing while entering the first resonant cavity 21, can there is resonant silencing with the first resonant cavity 21 in the part that air-breathing medium frequency is identical with the resonant frequency of the first resonant cavity 21, make the first resonant cavity 21 absorb the air-breathing medium frequency part identical with the resonant frequency of the first resonant cavity 21, and then reduced the air-breathing pressure pulsation forming in the first cylinder low voltage side, reach the object that reduces compressor noise and promoted the performance of compressor.
In the present embodiment, the resonant frequency of the first resonant cavity 21 is determined by the volume of this first resonant cavity 21 and the size of the first intercommunicating pore 22, and meets following relation:
Preferably, the first resonant cavity 21 is arranged on to the top of the first suction passage, such setting can prevent that the refrigeration oil or other the liquid that with absorbing gas belt, enter in compressor from accumulating in the first resonant cavity 21 effectively, affect the volume of the first resonant cavity 21, the resonant frequency of the first resonant cavity 21 is changed and then affect the effect of the first resonant cavity 21 resonance sound-absorbings.For reaching better erasure effect.Also a plurality of the first resonant cavities 21 can be set on the first cylinder, each first resonant cavity 21 is communicated with air intake passage respectively by the first intercommunicating pore corresponding with it, and there is respectively different resonant frequencies between a plurality of the first resonant cavities 21, this set can make a plurality of the first resonant cavities 21 respectively with the resonance sound-absorbing that carrys out the air-breathing generation of the different frequency in Self inhaling, eliminate the noise that is positioned at resonant frequency in air-breathing, the noise of compressor is effectively reduced.Due to the restriction in space, the first resonant cavity of offering on the first cylinder has quantitative requirement, therefore the resonant frequency of a plurality of the first resonant cavities should be respectively with air-breathing in each noise peak part corresponding one by one, to reach best erasure effect.
In embodiment one, the first resonant cavity 21 is opened on the first cylinder body, the shape of the first resonant cavity 21 can design as required, preferably, the first resonant cavity 21 can be arranged to circular hole or waist-shaped hole and to facilitate, the first cylinder body and flange 51 be processed.
Embodiment one compressor also includes the second cylinder and the second resonant cavity 41, the second cylinders are positioned at the below of the first cylinder, and is provided with dividing plate 52 between on the second cylinder and the first cylinder.On the second cylinder, there is the second cylinder body, on the second cylinder body, there are the second air intake passage 31, the second resonant cavities 41 and be communicated with the second air intake passage 31 by the second intercommunicating pore 42.Because the working principle of the second resonant cavity 41 is identical with the first resonant cavity 21 with working method, therefore do not repeat them here.In embodiment one, the second resonant cavity 41 is opened on the second cylinder body, preferably, the first resonant cavity 21 is arranged to circular hole or waist-shaped hole.
In addition, the position of the first resonant cavity 21 can arrange flexibly, except in embodiment one, the first resonant cavity 21 can be opened in beyond the scheme on the first cylinder body, in embodiment two as shown in Figure 4, also the first resonant cavity 21 can be opened on the flange 51 that is positioned at the first cylinder top, or, in embodiment three as shown in Figure 5, when the volume of the resonant cavity of needs excessive, in the time of cannot being arranged on separately on the first cylinder body or flange 51, also a part for the first resonant cavity 21 can be arranged on the first cylinder body, another part is arranged on flange 51, to expand the volume of the first resonant cavity 21.Accordingly, the first intercommunicating pore can only be arranged on the first cylinder body, or when the first resonant cavity is arranged on flange, the first intercommunicating pore also can be arranged on the first cylinder body and flange simultaneously.
Similar with the first resonant cavity 21, except being opened in separately, the second cylinder body is upper outside can also be arranged on dividing plate 52 the second resonant cavity 41 in the present embodiment, or a part for the second resonant cavity 41 is opened on the second cylinder body, and another part is opened on dividing plate 52.It should be noted that, when the first resonant cavity 21 is opened on the first cylinder and flange 51, the second cylinder is while being opened on the second cylinder and dividing plate 52, between the first cylinder and flange 51 or the second cylinder and dividing plate 52, should fit tightly, to guarantee the seal of the first resonant cavity 21 and the second resonant cavity 41.
The present invention also provides a kind of air conditioner, and the embodiment of air conditioner of the present invention has above-mentioned compressor, and the compressor in the present embodiment has decrease of noise functions, can effectively reduce the noise of air conditioner when work, provides better user to experience.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
