AI Technical Summary
During the start and stop of the compressor, the return air pipe is prone to vibrate greatly, resulting in the problem of excessive stress. Especially in the working conditions of high-temperature heat pump water heater, the traditional method has no obvious effect on reducing the start and stop stress of the return air pipe.
By providing an elastomer between the return air pipe and the reservoir or between the return air pipe and the compressor, the displacement of the return air pipe during the start-stop process of the compressor is limited or reduced, thereby reducing vibration.
It effectively reduces the vibration of the return air pipe when the compressor starts and stops, reduces the start and stop stress of the return air pipe, and improves the stability of the equipment.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compressors, in particular to a compressor assembly and a heating, ventilation and air conditioning (HVAC) device. Background Art
[0002] The information provided in this section is only background information related to the present disclosure and does not necessarily represent prior art.
[0003] During the startup and shutdown processes of a rotary compressor air-conditioning system, the compressor will swing. Under the excitation of the compressor swing, the sink bend of the suction pipe will swing along with the compressor, resulting in excessive stress in the suction pipe. To reduce the stress in the pipeline during the startup and shutdown of the compressor, the method of reducing the startup and shutdown frequency of the compressor is usually adopted to reduce the startup and shutdown torque of the compressor, so as to reduce the swing during the startup and shutdown of the compressor. However, for a high-temperature heat pump water heater, when starting and stopping under working conditions of high ambient temperature, high pressure, and high pressure ratio, this method has an insignificant effect on reducing the startup and shutdown stress of the suction pipe.

[0043] As Figures 1 to 8 shown, Figures 1 to 7 in Figure A represents the axial direction of the liquid storage tank 20 and the height direction of the compressor 10, and Figure B represents the radial direction of the liquid storage tank 20. Figure 8In the figure, C represents the first direction and D represents the second direction. A first aspect of the present utility model proposes a compressor assembly 101, which includes a compressor 10, a liquid storage tank 20, a return air pipe 30, and at least one elastomer 40. The compressor 10 has a suction port 11. The liquid storage tank 20 is communicated with the suction port 11. The return air pipe 30 is communicated with the liquid storage tank 20. The return air pipe 30 has a first portion 31 spaced from the liquid storage tank 20. The elastomer 40 is connected to at least one of the compressor 10, the liquid storage tank 20, and the first portion 31, and at least a part of the elastomer 40 is disposed between the first portion 31 and the liquid storage tank 20, or at least a part of the elastomer 40 is disposed between the first portion 31 and the compressor 10.
[0044] It can be understood that the refrigerant enters the liquid storage tank 20 through the return air pipe 30, and the refrigerant in the liquid storage tank 20 enters the compressor 10 through the suction port 11. The compressor 10 is used to compress the refrigerant into a high-pressure and high-temperature gas. The suction port 11 is usually arranged on the side of the compressor 10 and close to the bottom of the compressor 10. The liquid storage tank 20 can be arranged on the outer peripheral side of the compressor 10. The bottom end of the liquid storage tank 20 is connected to the suction port 11 through a pipeline, and this pipeline can play a supporting role for the liquid storage tank 20. The top end of the liquid storage tank 20 is connected and communicated with the return air pipe 30. When the compressor 10 is running, the compressor 10 generates vibrations by itself, and the liquid storage tank 20 and the return air pipe 30 connected to the compressor 10 vibrate due to the vibrations of the compressor 10. At this time, at least one elastomer 40 can be arranged between the return air pipe 30 and the liquid storage tank 20, so that the vibrations of the return air pipe 30 are absorbed by the elastomer 40 during vibration, and the elastomer 40 restricts the swing of the return air pipe 30, thereby reducing the excessive stress generated by the return air pipe 30 due to vibration. The elastomer 40 can be a sleeve structure or a block structure, and is installed and fixed by sleeving on the first portion 31 spaced between the return air pipe 30 and the liquid storage tank 20, or being clamped between the first portion 31 and the liquid storage tank 20. The elastomer 40 can be integrally formed by using an elastic material such as sponge or foam, and has a good vibration absorption effect.
[0045] The compressor assembly 101 proposed by the present utility model sets an elastomer 40 between the return air pipe 30 and the liquid storage tank 20 to limit or reduce the displacement of the return air pipe 30 relative to the liquid storage tank 20 of the compressor 10 during the start and stop of the compressor 10, thereby achieving the effect of reducing the start and stop stress of the return air pipe 30.
[0046] In some embodiments of the present utility model, the first portion 31 includes a first pipe section 32 spaced radially outside the liquid storage tank 20. The axial direction of the first pipe section 32 is parallel to the axial direction of the liquid storage tank 20. At least a part of the elastomer 40 is sleeved on the first pipe section 32, or at least a part of the elastomer 40 is clamped between the first pipe section 32 and the liquid storage tank 20.
[0047] It can be understood that the first part 31 of the suction pipe 30 includes a first pipe section 32 arranged on the outer peripheral side of the liquid storage tank 20. The first pipe section 32 can extend along the axial direction of the liquid storage tank 20, so as to enable the suction pipe 30 to extend from one axial end of the liquid storage tank 20 to the other axial end. The suction pipe 30 can be arranged in a coiled extension mode around the liquid storage tank 20 according to actual needs, so as to enhance the strength of the suction pipe 30 and reduce vibration. An elastomer 40 is sleeved on the first pipe section 32. The elastomer 40 can be arranged in a sleeve shape and sleeved on the first pipe section 32 when the suction pipe 30 is installed. A cut can also be made on the elastomer 40. After the suction pipe 30 is installed, the elastomer 40 is pressed onto the first pipe section 32 from the cut to achieve installation. The elastomer 40 can also be selected in a block structure, clamped between the first pipe section 32 and the liquid storage tank 20, or fixed on the liquid storage tank 20 or the first pipe section 32 through a clamp, or fixed on the first pipe section 32 by an adhesive method. By arranging the elastomer 40 between the first pipe section 32 and the liquid storage tank 20, the swinging amplitude of the suction pipe 30 when affected by the vibration of the compressor 10 is reduced.
[0048] In some embodiments of the present invention, the first part 31 includes a second pipe section 33 arranged at an angle to the axial direction of the liquid storage tank 20. Along the axial direction of the liquid storage tank 20, the second pipe section 33 is spaced from the liquid storage tank 20, and at least part of the elastomer 40 is sleeved on the second pipe section 33, or at least part of the elastomer 40 is clamped between the second pipe section 33 and the liquid storage tank 20.
[0049] It can be understood that the first part 31 of the suction pipe 30 includes a second pipe section 33 spaced at one axial end of the liquid storage tank 20. The second pipe section 33 can extend along the radial direction of the liquid storage tank 20, or has an arc-shaped pipe structure such as a U shape, so as to improve the anti-bending ability of the suction pipe 30 in certain directions. The extension mode of the second pipe section 33 can be specifically set according to actual needs, so as to enhance the strength of the suction pipe 30 and reduce vibration. An elastomer 40 is sleeved on the second pipe section 33. The elastomer 40 can be arranged in a sleeve shape and sleeved on the second pipe section 33 when the suction pipe 30 is installed. A cut can also be made on the elastomer 40. After the second pipe section 33 is installed, the elastomer 40 is pressed onto the second pipe section 33 from the cut to achieve installation. The elastomer 40 can also be selected in a block structure, clamped between the second pipe section 33 and one axial end of the liquid storage tank 20, or fixed on the liquid storage tank 20 or the second pipe section 33 through a clamp, or fixed on the second pipe section 33 by an adhesive method. By arranging the elastomer 40 between the second pipe section 33 and the liquid storage tank 20, the swinging amplitude of the suction pipe 30 when affected by the vibration of the compressor 10 is reduced, and further the phenomenon of stress exceeding the standard of the suction pipe 30 is reduced.
[0050] In some embodiments of the present utility model, the first portion 31 includes a first pipe section 32 and a second pipe section 33 that are sequentially connected and communicate with each other. The first pipe section 32 is disposed at intervals on the radial outer side of the liquid storage tank 20. The axial direction of the first pipe section 32 is parallel to the axial direction of the liquid storage tank 20. The second pipe section 33 is disposed at an angle to the axial direction of the liquid storage tank 20. Along the axial direction of the liquid storage tank 20, the second pipe section 33 is spaced from the liquid storage tank 20. The number of elastic bodies 40 is multiple. At least part of the elastic bodies 40 are clamped between the first pipe section 32 and the liquid storage tank 20. At least part of the elastic bodies 40 are disposed above the second pipe section 33 and abut against the second pipe section 33.
[0051] It can be understood that the first portion 31 of the return air pipe 30 includes a first pipe section 32 disposed at intervals on the outer peripheral side of the liquid storage tank 20. The first pipe section 32 can extend along the axial direction of the liquid storage tank 20 to enable the return air pipe 30 to extend from one axial end of the liquid storage tank 20 to the other axial end. The return air pipe 30 can be arranged in a coiled extension manner around the liquid storage tank 20 according to actual needs to enhance the strength of the return air pipe 30 and reduce vibration. And a second pipe section 33 disposed at intervals at one axial end of the liquid storage tank 20. The second pipe section 33 can extend along the radial direction of the liquid storage tank 20 or has an arc-shaped pipe structure such as a U-shape to improve the anti-bending ability of the return air pipe 30 in certain directions. The extension manner of the second pipe section 33 can be specifically set according to actual needs to enhance the strength of the return air pipe 30 and reduce vibration. Multiple elastic bodies 40 can be provided, and the elastic bodies 40 are in a block structure. Part of the elastic bodies 40 are clamped between the first pipe section 32 and one axial end of the liquid storage tank 20, or fixed to the liquid storage tank 20 or the first pipe section 32 by a clamp, and can also be fixed to the first pipe section 32 by an adhesive method. Part of the elastic bodies 40 are clamped between the second pipe section 33 and one axial end of the liquid storage tank 20, or fixed to the liquid storage tank 20 or the second pipe section 33 by a clamp, and can also be fixed to the second pipe section 33 by an adhesive method. By arranging the elastic bodies 40 between the first pipe section 32 and the liquid storage tank 20, and between the second pipe section 33 and the liquid storage tank 20, the swinging amplitude of the return air pipe 30 when affected by the vibration of the compressor 10 is reduced, thereby reducing the phenomenon of stress exceeding the standard of the return air pipe 30.
[0052] In some embodiments of the present utility model, the first portion 31 includes a first pipe section 32 and a second pipe section 33 that are sequentially connected and communicate with each other. The first pipe section 32 is disposed at intervals on the radial outer side of the liquid storage tank 20. The axial direction of the first pipe section 32 is parallel to the axial direction of the liquid storage tank 20. The second pipe section 33 is disposed at an angle with the axial direction of the liquid storage tank 20. Along the axial direction of the liquid storage tank 20, the second pipe section 33 is spaced from the liquid storage tank 20. The elastomer 40 includes a first elastic sleeve 41, a transition elastic sleeve 42, and a second elastic sleeve 43 that are sequentially connected. The first elastic sleeve 41 is sleeved on the first pipe section 32. The transition elastic sleeve 42 is sleeved at the connection between the first pipe section 32 and the second pipe section 33. The second elastic sleeve 43 is sleeved on the second pipe section 33.
[0053] It can be understood that the first portion 31 of the return air pipe 30 includes a first pipe section 32 disposed at intervals on the outer peripheral side of the liquid storage tank 20. The first pipe section 32 can extend along the axial direction of the liquid storage tank 20 to enable the return air pipe 30 to extend from one axial end of the liquid storage tank 20 to the other axial end, and a second pipe section 33 disposed at intervals at one axial end of the liquid storage tank 20. The second pipe section 33 can extend along the radial direction of the liquid storage tank 20, or has an arc-shaped pipe structure such as a U shape to improve the anti-bending ability of the return air pipe 30 in certain directions. The extension mode of the second pipe section 33 can be specifically set according to actual needs to enhance the strength of the return air pipe 30 and reduce vibration. One end of the second pipe section 33 is connected and communicates with one end of the first pipe section 32. The elastomer 40 can be set to have a structure adapted to the extension direction of the first portion 31, such as an arc-shaped sleeve structure, including a first elastic sleeve 41 sleeved on the first pipe section 32, a transition elastic sleeve 42 sleeved at the connection between the first pipe section 32 and the second pipe section 33, and a second elastic sleeve 43 sleeved on the second pipe section 33. By sleeving the elastomer 40 at the connection between the first pipe section 32 and the second pipe section 33, when the return air pipe 30 swings under vibration, the swing amplitude can be reduced through the elastomer 40, thereby reducing the phenomenon of stress exceeding the standard of the return air pipe 30.
[0054] In some embodiments of the present utility model, the compressor assembly 101 includes a plurality of elastomers 40. At least part of the elastomers 40 are sleeved on the first portion 31. At least part of the elastomers 40 are clamped between the first portion 31 and the liquid storage tank 20. At least part of the elastomers 40 are installed on the liquid storage tank 20.
[0055] It is understandable that a plurality of elastic bodies 40 may be provided, some of which are sleeve-type structures, and others are block-type structures. The elastic body 40 may be sleeved on the first part 31, or clamped between the first part 31 and the liquid storage tank 20, or installed on the liquid storage tank 20 according to actual needs. For example, when the first part 31 is arc-shaped or zigzag, the structure of the first part 31 may fix multiple positions of the elastic body 40, and clamping the block-type elastic body 40 between the first part 31 and the liquid storage tank 20 has better stability and lower cost. When the first part 31 is a straight tube type, the elastic body 40 may be sleeved on the first part 31, which is easy to install and has a better vibration reduction effect. The elastic body 40 may also be fixedly installed on the liquid storage tank 20 by bonding or fasteners.
[0056] In some embodiments of the present invention, the compressor assembly 101 also includes a heat exchanger 50, two of the compressor 10, the heat exchanger 50, the liquid storage tank 20 and the first part 31 are respectively located on opposite sides of the elastomer 40 along the first direction, and the other two are respectively located on opposite sides of the elastomer 40 along the second direction, and the first direction intersects with the second direction.
[0057] It can be understood that the compressor assembly 101 can be applied to the outdoor unit of the air conditioner, and the heat exchanger 50 can be a plate heat exchanger 50 in the outdoor unit of the air conditioner, which is used to exchange heat for the refrigerant. In actual applications, the compressor 10, the heat exchanger 50, the liquid storage tank 20 and the first part 31 can be used to fix the elastomer 40. For example, two of the compressor 10, the heat exchanger 50, the liquid storage tank 20 and the first part 31 are arranged relative to each other in a first direction, and the other two are arranged relative to each other in a second direction. The elastomer 40 is arranged on the return air pipe 30 and is located between the compressor 10, the heat exchanger 50, the liquid storage tank 20 and the first part 31, thereby fixing the elastomer 40.
[0058] In some embodiments of the present invention, the elastic body 40 is sandwiched between the compressor 10 and the heat exchanger 50 along the first direction, and the elastic body 40 is sandwiched between the liquid storage tank 20 and the first part 31 along the second direction.
[0059] It can be understood that the elastomer 40 is clamped between the compressor 10, the heat exchanger 50, the liquid storage tank 20 and the first part 31. Specifically, the left side of the elastomer 40 is in contact with the compressor 10, the right side of the elastomer 40 is against the heat exchanger 50, the front and upper parts of the elastomer 40 are against the lower part of the liquid storage tank 20, and the lower surface of the elastomer 40 is against the return air pipe 30. This can ensure that the position of the elastomer 40 will not move during the transportation of the whole machine. During the operation of the whole machine, since the elastomer 40 is relatively soft, it has no effect on the vibration of the return air pipe 30 and the noise of the whole machine. At the same time, during the shutdown process of the compressor 10, it can effectively reduce the shaking of the return air pipe 30 relative to the compressor 10, thereby effectively reducing the start-stop stress of the return air pipe 30.
[0060] In some embodiments of the present utility model, along the height direction of the compressor 10, the second pipe section 33 is located below the liquid storage tank 20.
[0061] It can be understood that the return air pipe 30 extends from above the liquid storage tank 20 to the side and then to below the liquid storage tank 20, so that the return air pipe 30 is arranged in a structure that coils around the liquid storage tank 20. Thereby, the overall strength of the return air pipe 30 is improved, the swing of the return air pipe 30 during the vibration of the compressor 10 is reduced, and thus the adverse stress of the return air pipe 30 is reduced.
[0062] In some embodiments of the present utility model, the liquid storage tank 20 is arranged on the radially outer side of the compressor 10, and the axial direction of the liquid storage tank 20 is parallel to the axial direction of the compressor 10.
[0063] It can be understood that the liquid storage tank 20 and the compressor 10 are arranged side by side. An air inlet 11 is arranged at the bottom of the side of the compressor 10. The air inlet 11 is connected to the outlet at the bottom of the liquid storage tank 20 through a pipeline. This pipeline can support the liquid storage tank 20. The close arrangement of the liquid storage tank 20 to the compressor 10 can make the overall structure more compact. And the relatively close distance between the liquid storage tank 20 and the compressor 10 makes the vibration of the liquid storage tank 20 smaller when the compressor 10 vibrates, thereby reducing noise and the adverse stress of the pipeline.
[0064] In some embodiments of the present utility model, the elastomer 40 is integrally formed of an elastic material such as sponge, foam or rubber. Other elastic materials can also be selected for the elastic material, which can be EPDM sponge, polyurethane foaming material, etc. For example, an EPDM sponge of 105*70*30mm.
[0065] The second aspect of the present utility model provides a heating, ventilation and air conditioning (HVAC) device 100, which includes the compressor assembly 101 proposed in the first aspect of the present utility model.
