As shown in fig. 2, the compressor of the first embodiment includes: the pump body assembly 20 comprises a shell 10, a pump body assembly 20 and a motor assembly 30. The pump body assembly 20 and the motor assembly 30 are both installed in the casing 10, and the casing 10 is provided with an air inlet and an air outlet. The suction inlet of the pump body assembly 20 is communicated with the air inlet of the housing 10, and the compressed air of the pump body assembly 20 passes through the motor assembly 30 for multiple times and is discharged from the air outlet.

By applying the technical scheme of the embodiment, the gas compressed by the pump body assembly 20 passes through the motor assembly 30 for multiple times, and due to the increase of the path, the energy of the high-pressure gas refrigerant in the compressor is reduced, the vibration is reduced, and the noise is reduced. The technical scheme of this embodiment has solved the great problem of noise when the compressor among the prior art uses effectively.

It should be noted that, from the side of the motor assembly 30 close to the pump body assembly 20 to the side of the motor assembly 30 far from the pump body assembly 20, the motor assembly 30 is passed once, and the internal clearance including the use of a pipeline or passing through the motor assembly 30 is included

As shown in fig. 2, in the first technical solution of the embodiment, the pump body assembly 20 and the motor assembly 30 divide the casing 10 into a first sound-deadening cavity 100 and a second sound-deadening cavity 200, the end wall of the motor assembly 30 and the casing 10 is the first sound-deadening cavity 100, the second sound-deadening cavity 200 is between the motor assembly 30 and the pump body assembly 20, and the air outlet is disposed on the side wall of the second sound-deadening cavity 200. The provision of first and second muffling

cavities

100 and 200 further eliminates the noise produced by the compressor. Specifically, the space within first sound-deadening chamber 100 is large, and the expansion of the compressed gas within first sound-deadening chamber 100 can effectively eliminate noise.

As shown in fig. 2, in the first technical solution of the embodiment, the compressor further includes a communication pipe 40, a first end of the communication pipe 40 is hermetically connected to an outlet of the pump body assembly 20, and a second end of the communication pipe 40 is communicated with the first muffling chamber 100. The provision of the communication pipe 40 effectively eliminates noise generated in the second sound-deadening chamber 200 by the compressed gas coming out of the pump body assembly 20. Specifically, since the space of the first muffling chamber 100 is large, the noise generated after the gas compressed by the pump body assembly 20 enters the first muffling chamber 100 through the communicating pipe 40 is small.

As shown in fig. 2, in the first embodiment, the motor assembly 30 includes a stator 31 and a rotor 32, a gap is formed between the stator 31 and the housing 10, and the communication pipe 40 is disposed in the gap. The above structure is compact without providing an additional space for the communication pipe 40 or connecting the communication pipe 40 to the outside of the housing 10.

As shown in fig. 2, in the first embodiment, the rotor 32 is provided with a flow hole penetrating the first muffling chamber 100 and the second muffling chamber 200. The arrangement of the flow holes facilitates the compressed gas in first sound-deadening chamber 100 to enter second sound-deadening chamber 200. The flow holes are arranged on the rotor 32, on one hand, compressed gas can exchange heat with the motor assembly 30, and on the other hand, the structure of the compressor is more compact.

As shown in fig. 2, in the solution of the present embodiment, the ratio of the volume of first muffling cavity 100 to the volume of second muffling cavity 200 is greater than 1.5. The above structure ensures that the volume of the first muffling chamber 100 is greater than the volume of the second muffling chamber 200, so that the volume of the compressed gas is suddenly enlarged when the compressed gas enters the first muffling chamber 100, thereby greatly reducing the noise generated by the compressed gas under a high pressure. As shown in fig. 6 and 7, it is proved by practice that, under the condition of ensuring a certain volume of the compressor, the silencing effect is more obvious when the volume of the first silencing chamber 100 is V1, the volume of the second silencing chamber 200 is V2, and V1/V2 is greater than 1.5. The volume of the first silencing cavity 100 is enlarged, and the silencing effect is good.

It should be noted that, the motor of the compressor of the application moves to the pump body assembly, so that the height of the motor can be reduced, the height of the whole compressor or a rotating part of the compressor is reduced, the vibration of the compressor is reduced, and the noise is reduced. In addition, the height of the shaft of the motor is reduced, the arm length of the cantilever beam is shortened, the deflection of the shaft system is reduced, and the effect of reducing the noise of the compressor can be achieved.

As shown in fig. 2, 6 and 7, in the first embodiment, the volume of the first muffling chamber 100 is V1, the displacement volume of the compressor is V, and V1/V is greater than 8. The above structure makes the first muffling chamber 100 have a larger volume, which can reduce the noise of the compressor.

As shown in fig. 3, the second embodiment is different from the first embodiment in that the compressor further includes a sound-deadening structure, and the sound-deadening structure is disposed in the first sound-deadening chamber 100. The arrangement of the silencing structure further reduces the noise generated by the compressor. Specifically, the silencing structure comprises a silencing plate 50, the silencing plate 50 is arranged in a first silencing cavity 100, the silencing plate 50 divides the first silencing cavity 100 into a first sub silencing cavity 101 and a second sub silencing cavity 102, the first sub silencing cavity 101 is formed between the silencing plate 50 and an end plate of the shell 10, the second sub silencing cavity 102 is formed between the silencing plate 50 and the motor assembly 30, and the second end of the communication pipe 40 is located in the first sub silencing cavity 101. The structure has lower processing cost and convenient arrangement. The sound-absorbing plate 50 may be welded to the inner wall of the housing 10. In the technical solution of this embodiment, the sound-absorbing plate 50 is a curved plate, and the arrangement of the curved plate makes the time for the compressed gas to reach the sound-absorbing plate 50 different, which is more beneficial to eliminating noise. The acoustical panel 50 may be provided with a large via. The end plate of the case 10 refers to the upper end plate in fig. 3.

As shown in fig. 4, the third embodiment is different from the second embodiment in that a plurality of through holes are provided in the sound-absorbing plate 50. The provision of a plurality of through holes facilitates the compressed gas to pass more uniformly through the panel 50. It should be noted that the plurality of through holes may not be uniformly arranged, so that the compressed gas passes through the muffling plate 50 more uniformly according to the passing condition of the compressed gas. Thus, the effect of reducing noise is more obvious.

As shown in fig. 5, the fourth embodiment is different from the third embodiment in that the sound-deadening plate 50 is a flat plate. One or more through holes may be formed in the flat plate. When the number of the via holes is multiple, the sizes of the via holes can be the same or different, and the via holes can be uniformly arranged on the flat plate or non-uniformly arranged on the flat plate.

The present application also provides a household appliance including a compressor. The compressor is the above compressor. It should be noted that the household appliance may be an air conditioner, a refrigerator, or the like.
