Embodiment Construction

[0030] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] Compressor noise is not only a key technical indicator, but also a yardstick for direct user experience. At the same time, noise reduction design, especially fluid noise reduction design, has always been a difficult point for compressors. Especially after the air conditioner is converted to direct current, the frequency conversion drive of the compressor makes the air flow noise a bottleneck in the improvement of the compressor design. Because the noise comes from the work done by the pump body of the compressor on the fluid, the conventional noise reduction methods are to design orifices (such as Helmholtz resonance chamber) and shape design of the muffler on the pump body machinery. I...

Abstract

The invention provides a muffler plate, a motor and an air conditioner. The muffler plate comprises a plate body and a medium channel arranged inside the plate body. The two ends of the medium channel penetrate through the surface of the plate body, and a medium inlet and a medium outlet are formed. The medium channel comprises a reducer. In the medium flowing direction, the cross section area of the reducer is gradually increased. According to the technical scheme, the problem that in the prior art, working noise of a compressor is large is solved.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a sound-absorbing plate, a motor and an air conditioner. Background technique [0002] Compressor noise is not only a key technical indicator, but also a yardstick for direct user experience. At the same time, noise reduction design, especially fluid noise reduction design, has always been a difficult point for compressors. Especially after the air conditioner is converted to direct current, the frequency conversion drive of the compressor makes the air flow noise a bottleneck in the improvement of the compressor design. Because the noise comes from the work done by the pump body of the compressor on the fluid, the conventional noise reduction methods are to design orifices on the pump body (such as the Helmholtz resonance cavity), design the shape of the muffler, etc., while the above-mentioned orifices The noise reduction effect of the design is not ideal, and ...
