Description

Technical Field

[0001] The present invention belongs to the technical field of air-conditioning structures, and in particular relates to a compressor, an air-conditioning outdoor unit and an air-conditioning system. Background Art

[0002] In air-conditioning systems, air-conditioning operating noise is an important indicator for measuring air-conditioning performance, and the main source of air-conditioning noise is the noise generated by the operation of the compressor. There are three main sources of compressor operating noise, among which the air flow pulsation noise formed by gas flow accounts for an important proportion. The refrigerant is compressed in the cylinder, and the process of high-pressure gas being discharged from the cylinder will generate a lot of noise. Therefore, most existing compressors use a connected silencer cavity at the exhaust port of the cylinder to achieve a better noise reduction effect.

[0003] However, an overly large silencer cavity results in significant energy loss when the compressor is running at low frequencies, as excessive high-pressure gas remains in the cavity and is not discharged. An overly small silencer cavity does not completely silence the air at high frequencies. The silencer cavity in related technologies has the following main problems:

[0004] 1. The volume of the silencer chamber is fixed, and the best silencer effect cannot be achieved;

[0005] 2. The silencer cavity has no buffering, and the silencer process is accompanied by large vibrations. Summary of the Invention

[0006] The present invention provides a compressor, an air-conditioning outdoor unit and an air-conditioning system, which are used to solve the technical problem in the related art that the volume of the silencer cavity is fixed and there is no buffer.

[0007] The present invention is achieved through the following technical solution: A compressor comprising:

[0008] A body, the body being provided with a first exhaust port and a second exhaust port for alternate exhaust, the body being provided with a first silencing chamber and a second silencing chamber, the first silencing chamber being connected to the first exhaust port, the second silencing chamber being connected to the second exhaust port, the body being further provided with a passage, the passage being connected to the first silencing chamber and the second silencing chamber;

[0009] a partition member installed in the channel;

[0010] When exhausting gas from the first exhaust port, part of the exhausted gas enters the first muffler cavity and the channel and acts on the partition member to drive the partition member to move or deform toward the second muffler cavity;

[0011] When exhausting gas from the second exhaust port, part of the exhausted gas enters the second muffler cavity and the channel and acts on the partition member to drive the partition member to move or deform toward the first muffler cavity.

[0012] Furthermore, in order to better implement the present invention, the partition member is a sliding rod adapted to the channel, and the sliding rod is slidably installed in the channel.

[0013] Furthermore, in order to better implement the present invention, the sliding rod is a structural member made of steel or plastic.

[0014] Furthermore, in order to better implement the present invention, the sliding rod is a hollow rod body.

[0015] Furthermore, in order to better implement the present invention, the partition member is a deformable eardrum, and the deformable eardrum is fixed to the inner wall of the channel.

[0016] Furthermore, in order to better implement the present invention, the deformable eardrum is a rubber plate, and the circumferential outer wall of the rubber plate is bonded to the inner wall of the channel by adhesive.

[0017] Furthermore, in order to better realize the present invention, the main body is a two-cylinder compressor including an upper cylinder body and a lower cylinder body, a middle partition is installed between the upper cylinder body and the lower cylinder body, the first silencer chamber is arranged on the end surface of the upper cylinder body and is located away from the lower cylinder body, the second silencer chamber is arranged on the end surface of the lower cylinder body and is located away from the upper cylinder body, the channel passes through the side wall of the upper cylinder body and the side wall of the lower cylinder body, and the channel also passes through the middle partition.

[0018] Furthermore, in order to better realize the present invention, the main body is a single-cylinder compressor including a single-cylinder body, the first muffler chamber and the second muffler chamber are respectively arranged at both ends of the single-cylinder body, and the channel runs through the side wall of the single-cylinder body.

[0019] The air-conditioning outdoor unit provided by the present invention includes the above-mentioned compressor.

[0020] The air-conditioning system provided by the present invention includes the above-mentioned air-conditioning outdoor unit.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) The compressor provided by the present invention includes a body and a partition. The body is provided with a first exhaust port and a second exhaust port for alternating exhaust. The body is also provided with a first muffler chamber connected to the first exhaust port and a second muffler chamber connected to the second exhaust port. The body is also provided with a channel connecting the first muffler chamber and the second muffler chamber, and the partition is installed in the channel. When exhaust is discharged from the first exhaust port, part of the exhausted gas enters the first muffler chamber and the channel and acts on the partition to drive the partition to move or deform toward the second muffler chamber. When exhaust is discharged from the second exhaust port, part of the exhausted gas enters the second muffler chamber and the channel and acts on the partition to drive the partition to move or deform toward the first muffler chamber.

[0023] By setting the above-mentioned channels and partitions, part of the high-pressure gas when exhausting from a certain exhaust port enters the corresponding silencer chamber and will act on the partition to drive the partition to move or deform toward the other silencer chamber, thereby increasing the volume of the silencer chamber where the high-pressure gas enters. When exhausting from the other exhaust port, the partition moves in the opposite direction or deforms. In this way, the partition moves back and forth or deforms between the two silencer chambers, thereby changing the volume of the silencer chamber where the high-pressure gas enters, so that the silencer chamber can cover (that is, reduce) the noise under different working conditions from low frequency to high frequency. The size of the silencer chamber can be adjusted according to the frequency during the operation of the compressor, which has a wider range of silence for the compressor and a better effect.

[0024] Moreover, when the compressor is at low frequency, the exhaust gas speed and pressure are small, the force of impact on the partition is small, the displacement or deformation of the partition is small, and the volume of the silencer cavity obtained after the change is small, that is, the opening of the silencer cavity is small. Therefore, there is less residual high-pressure gas in the silencer cavity, and the compressor high-pressure gas loss is small, which is beneficial to reducing the energy efficiency loss caused by the silencer cavity; when the compressor is at high frequency, the compressor exhaust speed is fast, the exhaust pressure is high, the impact on the partition is large, the displacement or deformation of the partition is large, and the volume of the silencer cavity after the change is large, which is beneficial to the greater silencer demand of the compressor at high frequency.

[0025] In addition, since the high-pressure gas in the silencer chamber will remain in it, when the first exhaust port is exhausted, the partition piece moves toward the second silencer chamber or deforms, and the high-pressure gas remaining in the second silencer chamber forms a buffer for the partition piece. When the second exhaust port is exhausted, the partition piece moves toward the first silencer chamber or deforms, and the high-pressure gas remaining in the first silencer chamber forms a buffer for the partition piece. This can help reduce the vibration caused by the silencing process.

[0026] (2) The air-conditioning outdoor unit provided by the present invention includes the above-mentioned compressor, so the noise and vibration generated by the air-conditioning outdoor unit during operation are smaller.

[0027] (3) The air-conditioning system provided by the present invention includes the above-mentioned air-conditioning outdoor unit, so the air-conditioning system has better effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0044] Example 1:

[0045] like Figures 1 to 5 As shown, the compressor provided in this embodiment includes a body 1 and a partition member. The body 1 is provided with a first exhaust port 11 and a second exhaust port 12 for alternate exhaust. The body 1 is also provided with a first muffler chamber 13 communicating with the first exhaust port 11 and a second muffler chamber 14 communicating with the second exhaust port 12. The body 1 is also provided with a channel 15, which connects the first muffler chamber 13 and the second muffler chamber 14. The partition member is installed in the channel 15. When exhaust is discharged from the first exhaust port 11, part of the exhausted gas enters the first muffler chamber 13 and the channel 15 and acts on the partition member to drive the partition member to move or deform toward the second muffler chamber 14. When exhaust is discharged from the second exhaust port 12, part of the exhausted gas enters the second muffler chamber 14 and the channel 15 and acts on the partition member to drive the partition member to move or deform toward the first muffler chamber 13.

[0046] By setting the above-mentioned channel 15 and partition, part of the high-pressure gas discharged from a certain exhaust port enters the corresponding silencer cavity and acts on the partition, driving the partition to move or deform toward the other silencer cavity, thereby increasing the volume of the silencer cavity where the high-pressure gas enters. When the other exhaust port is exhausted, the partition moves or deforms in the opposite direction. In this way, the partition moves back and forth or deforms between the two silencer cavities, thereby changing the volume of the silencer cavity where the high-pressure gas enters, so that the silencer cavity can cover (that is, reduce) noise from low frequency to high frequency working conditions. During the operation of the compressor, the size of the silencer cavity can be adjusted according to the frequency, which has a wider range of compressor silencing and better effect.

[0047] Moreover, when the compressor is at low frequency, the exhaust gas speed and pressure are small, the force of impact on the partition is small, the displacement or deformation of the partition is small, and the volume of the silencer cavity obtained after the change is small, that is, the opening of the silencer cavity is small. Therefore, there is less residual high-pressure gas in the silencer cavity, and the high-pressure gas loss of the compressor is small, which is beneficial to reducing the energy efficiency loss caused by the silencer cavity; when the compressor is at high frequency, the compressor exhaust speed is fast, the exhaust pressure is high, the impact on the partition is large, the displacement or deformation of the partition is large, and the volume of the silencer cavity after the change is large, which is beneficial to the greater silencer demand of the compressor at high frequency.

[0048] In addition, since the high-pressure gas in the silencer chamber will remain in it, when the first exhaust port 11 is exhausted, the partition piece moves toward the second silencer chamber 14 or deforms, and the high-pressure gas remaining in the second silencer chamber 14 forms a buffer for the partition piece. When the second exhaust port 12 is exhausted, the partition piece moves toward the first silencer chamber 13 or deforms, and the high-pressure gas remaining in the first silencer chamber 13 forms a buffer for the partition piece. This can help reduce the vibration caused by the silencing process.

[0049] Optionally, the main body 1 in this embodiment is a two-cylinder compressor including an upper cylinder body 4 and a lower cylinder body 5, and a middle partition 6 is installed between the upper cylinder body 4 and the lower cylinder body 5, and the above-mentioned first muffler chamber 13 is provided on the end surface of the upper cylinder body 4 and is located away from the lower cylinder body 5, that is, the first muffler chamber 13 is provided on one end surface of the upper cylinder body 4 away from the lower cylinder body 5, and the second muffler chamber 14 is provided on the end surface of the lower cylinder body 5 and is located away from the upper cylinder body 4, that is, the second muffler chamber 14 is provided on one end surface of the lower cylinder body 5 away from the upper cylinder body 4, a first through hole is provided inside the side wall of the above-mentioned upper cylinder body 4, a second through hole is provided inside the side wall of the above-mentioned lower cylinder body 5, and a third through hole is provided in the above-mentioned middle partition 6, the first through hole, the second through hole and the third through hole are connected and spliced ​​to form the above-mentioned channel 15, and the channel 15 is a straight hole, that is, the channel 15 passes through the side wall of the above-mentioned upper cylinder body 4 and the side wall of the lower cylinder body 5 and the above-mentioned middle partition 6.

[0050] Optionally, the main body 1 in this embodiment is a single-cylinder compressor including a single-cylinder body 7, the first muffler chamber 13 and the second muffler chamber 14 are respectively arranged at both ends of the single-cylinder body 7, and the channel 15 is opened inside the side wall of the single-cylinder body 7, and the channel 15 is also a straight hole.

[0051] Example 2:

[0052] This embodiment is a specific implementation of the embodiment 1. The compressor provided in this embodiment is substantially the same as that in the embodiment 1, except that:

[0053] like Figure 1 and Figure 2 As shown, the partition member in this embodiment can move in the above-mentioned channel 15. Specifically, the partition member is a slide bar 2 adapted to the above-mentioned channel 15, the slide bar 2 is slidably installed in the above-mentioned channel 15, and the length of the slide bar 2 is less than the length of the above-mentioned channel 15.

[0054] When the high-pressure gas enters the first silencer chamber 13, the high-pressure gas impacts the slide rod 2 and causes the slide rod 2 to move toward the second silencer chamber 14. At this time, the volume of the first silencer chamber 13 increases and the volume of the second silencer chamber 14 decreases. The change in the volume of the first silencer chamber 13 enables the first silencer chamber 13 to cover noise under different working conditions from low frequency to high frequency, and the high-pressure gas remaining in the second silencer chamber 14 has a buffering effect on the slide rod 2, thereby reducing vibration during the silencer process.

[0055] When the high-pressure gas enters the second silencer chamber 14, the high-pressure gas impacts the slide rod 2 and causes the slide rod 2 to move toward the first silencer chamber 13. At this time, the volume of the second silencer chamber 14 increases and the volume of the first silencer chamber 13 decreases. The volume change of the second silencer chamber 14 enables the second silencer chamber 14 to cover noise under different working conditions from low frequency to high frequency, and the high-pressure gas remaining in the first silencer chamber 13 has a buffering effect on the slide rod 2, thereby reducing vibration during the silencer process.

[0056] Optionally, the slide bar 2 in this embodiment is a structural member made of steel or plastic. And the slide bar 2 is a hollow rod body. Of course, the plastic used to make the slide bar 2 is high-strength hard plastic.

[0057] Example 3:

[0058] This embodiment is another specific implementation of the embodiment 1. The compressor provided in this embodiment is substantially the same as that in the embodiment 1, except that:

[0059] The partition member in this embodiment can be deformed in the above-mentioned channel 15. Specifically, Figure 4 As shown, the partition member is a deformable eardrum 3 , and the deformable eardrum 3 is fixed to the inner wall of the channel 15 .

[0060] When the high-pressure gas enters the first silencer chamber 13, the high-pressure gas impacts the deformable eardrum 3 and causes the deformable eardrum 3 to deform toward the second silencer chamber 14. At this time, the volume of the first silencer chamber 13 increases and the volume of the second silencer chamber 14 decreases. The change in the volume of the first silencer chamber 13 enables the first silencer chamber 13 to cover noise under different working conditions from low frequency to high frequency, and the high-pressure gas remaining in the second silencer chamber 14 has a buffering effect on the deformable eardrum 3, thereby reducing vibration during the silencer process.

[0061] When the high-pressure gas enters the second silencer chamber 14, the high-pressure gas impacts the deformable eardrum 3 and causes the deformable eardrum 3 to deform toward the first silencer chamber 13. At this time, the volume of the second silencer chamber 14 increases and the volume of the first silencer chamber 13 decreases. The volume change of the second silencer chamber 14 enables the second silencer chamber 14 to cover noise under different working conditions from low frequency to high frequency, and the high-pressure gas remaining in the first silencer chamber 13 has a buffering effect on the deformable eardrum 3, thereby reducing vibration during the silencer process.

[0062] Optionally, the deformable eardrum 3 in this embodiment is a rubber sheet, the circumferential outer wall of which is bonded to the inner wall of the channel 15 with a high-strength adhesive. The rubber sheet is provided in one piece and is located in the middle of the channel 15. If the main body 1 is a two-cylinder compressor, the rubber sheet is bonded and fixed to the middle of the third through hole in the middle diaphragm 6.

[0063] Of course, if Figure 5 As shown, in this embodiment, the number of rubber sheets bonded and fixed in the channel 15 can also be two, one of which is located near the first muffler chamber 13 and the other is located near the second muffler chamber 14. If the main body 1 is a two-cylinder compressor, the two rubber sheets are bonded and fixed in the first through hole of the upper cylinder body 4 and the second through hole of the lower cylinder body 5, respectively.

[0064] Example 4:

[0065] This embodiment provides an air-conditioning outdoor unit, which adopts the above-mentioned compressor, so the noise and vibration generated by the air-conditioning outdoor unit during operation are smaller.

[0066] Example 5:

[0067] This embodiment provides an air-conditioning system that uses the above-mentioned air-conditioning outdoor unit, so the air-conditioning system has a better effect.

[0068] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope of the present invention should be included within the scope of protection of the present invention.
