In detail, in the operation process of the compressor, when pressure relief is needed, the pressure relief valve opens the pressure relief opening, and the gas in the compression cavity is discharged through the second exhaust channel. When the compressor exhausts, the pressure relief valve closes the pressure relief opening, and the gas in the compression cavity is exhausted through the second exhaust port, the first exhaust channel and the second exhaust channel.

For example, the plurality of exhaust passages includes a first exhaust passage and a second exhaust passage, wherein the first exhaust passage and the second exhaust passage communicate through a gap. When the compressor is exhausted, high-temperature and high-pressure gas in the compression cavity is exhausted through the second exhaust port, part of the high-temperature and high-pressure gas is exhausted through the first exhaust channel, and part of the high-temperature and high-pressure gas flows to the second exhaust channel through the gap and is exhausted through the second exhaust channel.

The amount of sound damping during operation of the compressor is reduced, resulting in a reduced sound damping effect, although the mutual communication between at least two exhaust passages can be ensured.

In one possible solution, the plurality of exhaust passages includes a first exhaust passage and a second exhaust passage; the first exhaust passage and the second exhaust passage are arranged radially and at intervals from inside to outside.

In this technical scheme, a plurality of exhaust channels include first exhaust channel and second exhaust channel, and first exhaust channel and second exhaust channel are along radial, and from inside to outside interval arrangement, can understand that the compressor still includes the check valve, and the check valve generally sets up the central point of baffle to can be when the compressor shut down, partial closing cap second gas vent, in order to prevent high temperature high pressure gas to flow back to the compression intracavity through the second gas vent, and then lead to the problem of compressor reversal.

Through radial with first exhaust passage and second exhaust passage, and by interior and outside interval arrangement, can prevent that the check valve from shelter from the exhaust passage to keeping away from or being close to the in-process of second gas vent, and then lead to the problem that the exhaust resistance increases, ensure the steady operation of compressor.

In practical application, the cross section of each first exhaust sub-channel may be U-shaped, and the number of the first exhaust sub-channels is greater than or equal to 2, which may be specifically set according to practical needs.

The second exhaust passage comprises a plurality of second exhaust sub-passages, and the plurality of second exhaust sub-passages are distributed along the circumferential direction at intervals, namely, when the compressor is exhausting, gas is split, so that exhaust pulsation and exhaust noise in the exhaust process of the compressor can be reduced while the exhaust resistance is not improved, and the overall noise of the compressor is further reduced.

In practical application, the cross section shape of each second exhaust sub-channel may be circular, and the number of the second exhaust sub-channels is greater than or equal to 2, which may be specifically set according to practical needs.

The plurality of second exhaust sub-channels are radially outward of the plurality of first exhaust sub-channels. Therefore, the check valve can be prevented from shielding the exhaust passage in the process of being far away from or close to the second exhaust port, the problem of increasing the exhaust resistance is further caused, and the stable operation of the compressor is ensured.

In one possible technical scheme, the through-flow sectional area A of the first exhaust channel and the through-flow sectional area B of the second exhaust channel meet the requirement of 0.5-2.

In one possible solution, the compressor further comprises a check valve provided in the partition and movable with respect to the partition, the check valve being intended to be located at the second discharge port when the compressor is inactive.

In this solution, it is defined that the compressor further comprises a check valve, in particular the check valve is arranged on the partition, and the check valve is movable relative to the partition, in particular the check valve is movable relative to the partition towards or away from the second discharge opening.

The check valve can be located at the second discharge port when the compressor is shut down. As can be appreciated, when the compressor is discharging, the high pressure gas will push the check valve to move to the side far away from the second discharge port, so as to reduce the discharge resistance; when the compressor is stopped, part of high-pressure gas flowing out of the exhaust channel can flow back, the high-pressure gas flow can push the check valve, meanwhile, due to the gravity factor of the check valve, the check valve moves to one side close to the second exhaust port so as to partially cover the second exhaust port, the problem that the high-pressure gas flows back into the compression cavity through the second exhaust port and then is reversed after the compressor is stopped is solved.

In this embodiment, the range of values for the axial height of the gap between the flange 140 and the side of the compression assembly 120 facing the diaphragm 130 is defined. Therefore, the exhaust noise of the compressor 100 can be further reduced while the exhaust resistance of the compressor 100 is reduced in response to different working conditions of the compressor 100, the overall noise of the compressor 100 is further reduced, the quality of the air conditioner with the compressor 100 is improved, and the use experience of a user is further improved.

It will be appreciated that if the axial height of the gap is large, i.e. greater than 5mm, that is to say the cross-sectional area of the flow through which at least two exhaust channels communicate with each other is large. The amount of muffling during the operation of the compressor 100 is reduced, resulting in a reduction in muffling effect, although the communication between at least two exhaust passages can be ensured.

As shown in fig. 1, 2, 3, 4 and 5, further, on the basis of the above-described embodiment, the plurality of exhaust passages includes a first exhaust passage 131 and a second exhaust passage 132; the first and second exhaust passages 131 and 132 are disposed radially and at intervals from inside to outside.

In this embodiment, the plurality of exhaust passages includes a first exhaust passage 131 and a second exhaust passage 132, and the first exhaust passage 131 and the second exhaust passage 132 are radially arranged at intervals from inside to outside, it can be understood that the compressor 100 further includes a check valve 150, and the check valve 150 is generally disposed at a center position of the partition 130 and can partially cover the second exhaust port 122 when the compressor 100 is stopped, so as to prevent high-temperature and high-pressure gas from flowing back into the compression chamber 121 through the second exhaust port 122, thereby causing a problem of reverse rotation of the compressor 100.

By arranging the first and second exhaust passages 131 and 132 radially and at intervals from inside to outside, the check valve 150 can be prevented from shielding the exhaust passage in the process of moving away from or approaching the second exhaust port 122, thereby causing the problem of increased exhaust resistance and ensuring stable operation of the compressor 100.

As shown in fig. 3 and 4, further, the first exhaust passage 131 includes a plurality of first exhaust sub-passages 1311, and the plurality of first exhaust sub-passages 1311 are arranged at intervals in the circumferential direction, on the basis of the above-described embodiment; and/or the second exhaust passage 132 includes a plurality of second exhaust sub-passages 1321, the plurality of second exhaust sub-passages 1321 being circumferentially spaced apart.

In this embodiment, the first exhaust passage 131 includes a plurality of first exhaust sub-passages 1311, and the plurality of first exhaust sub-passages 1311 are arranged at intervals in the circumferential direction, that is, the gas is split when the compressor 100 is exhausting, so that exhaust pulsation and exhaust noise in the exhaust process of the compressor 100 can be reduced while the exhaust resistance is not improved, and thus the overall noise of the compressor 100 can be reduced.

In practical applications, the cross-sectional shape of each first exhaust sub-channel 1311 may be U-shaped, and the number of the first exhaust sub-channels 1311 is greater than or equal to 2, which may be specifically set according to practical needs.

The second exhaust passage 132 includes a plurality of second exhaust sub-passages 1321, and the plurality of second exhaust sub-passages 1321 are arranged at intervals along the circumferential direction, that is, when the compressor 100 exhausts, gas is split, so that exhaust pulsation and exhaust noise in the exhaust process of the compressor 100 can be reduced while the exhaust resistance is not improved, and the overall noise of the compressor 100 is reduced.

In practical applications, the cross-sectional shape of each second exhaust sub-passage 1321 may be a circle, and the number of the second exhaust sub-passages 1321 is greater than or equal to 2, which may be specifically set according to practical needs.

Radially, the plurality of second exhaust sub-passages 1321 are located outside of the plurality of first exhaust sub-passages 1311. Thus, the check valve 150 can be prevented from blocking the discharge passage in a process of moving away from or approaching the second discharge port 122, thereby causing a problem of an increase in discharge resistance, and ensuring stable operation of the compressor 100.

Further, on the basis of the above embodiment, the through-flow sectional area a of the first exhaust passage 131 and the through-flow sectional area B of the second exhaust passage 132 satisfy 0.5.ltoreq.a/b.ltoreq.2.

In this embodiment, the ratio of the through-flow cross sections of the first exhaust passage 131 and the second exhaust passage 132 is between 0.5 and 2, so that the exhaust noise of the compressor 100 can be reduced without affecting the exhaust efficiency of the compressor 100, i.e. the air flow noise in the exhaust process of the compressor 100 can be greatly reduced without increasing the exhaust resistance, and the overall noise of the compressor 100 can be further reduced.

As shown in fig. 1, 2 and 6, further, the compressor 100 further includes a check valve 150, where the check valve 150 is disposed on the partition 130 and is capable of moving relative to the partition 130, and the check valve 150 is disposed at the second exhaust port 122 when the compressor 100 stops operating.

When the compressor is stopped, part of the high-pressure gas flowing out of the exhaust passage flows back, the high-pressure gas flow pushes the check valve 150, and meanwhile, due to the gravity of the check valve 150, the check valve 150 moves to a side close to the second exhaust port 122 to partially cover the second exhaust port 122, so that the high-pressure gas is reduced to flow back into the compression chamber 121 through the second exhaust port 122, and the problem of reverse rotation of the compressor 100 after the compressor is stopped is caused.

By arranging the installation cavity 160, at least a part of the check valve 150 is arranged in the installation cavity 160, the occupied space of the check valve 150 in the axial direction of the shell 110 of the compressor 100 can be reduced, the occupied space of the whole machine of the compressor 100 in the axial direction is further reduced, and the compressor 100 is miniaturized.

When the compressor is stopped, part of the high-pressure gas flowing out of the discharge passage flows back through the through hole 170 and pushes the check valve 150, and meanwhile, due to the gravity of the check valve 150, the check valve 150 moves to one side close to the second discharge port 122 to partially cover the second discharge port 122, so that the high-pressure gas is reduced from flowing back into the compression chamber 121 through the second discharge port 122, and the problem of reverse rotation of the compressor 100 after the stop is caused.

By providing the through hole 170, when the compressor 100 is stopped, part of high-pressure gas flows back through the through hole 170, so that the check valve 150 is pushed to rapidly cover the second exhaust port 122, and the compressor 100 is ensured not to be reversed when stopped.

Along the radial direction of the partition 130, the plurality of exhaust passages are located at the outer side of the through hole 170, that is, along the radial direction, the plurality of exhaust passages are located as far from the check valve 150 as possible, so that the check valve 150 can be effectively prevented from shielding the exhaust passages in the process of being far from or near to the second exhaust port 122, thereby causing the problem of increasing the exhaust resistance, and ensuring the stable operation of the compressor 100.

In a specific embodiment, further, at least one exhaust passage is disposed closer to the outer edge of the partition 130 than the mounting cavity 160.
