The support assembly is movably disposed in the first mounting groove so that the first air chamber and the second air chamber are respectively in openable and closable communication with the interior of the first mounting groove.
[0015] Furthermore, the first mounting groove has a first annular sidewall and a second annular sidewall arranged radially at intervals along the moving scroll. The first annular sidewall is closer to the axis of the moving scroll than the second annular sidewall. The first air chamber communicates with the interior of the first mounting groove through the first annular sidewall, and the second air chamber communicates with the interior of the first mounting groove through the second annular sidewall.
[0016] Furthermore, the first annular sidewall and / or the second annular sidewall have a second mounting groove on the side facing the moving scroll, and the compressor also includes a sealing assembly, at least a portion of which is disposed in the second mounting groove and abuts against the moving scroll.
[0017] Furthermore, the first annular sidewall has at least one air inlet communication channel, and the first air chamber is connected to the interior of the first mounting groove through the air inlet communication channel; the second annular sidewall has at least one air outlet communication channel, and the second air chamber is connected to the interior of the first mounting groove through the air outlet communication channel.
[0018] Furthermore, the support assembly has at least one air inlet channel and at least one air outlet channel. When the support assembly is in the air inlet position, the air inlet channel is connected to the air inlet connecting channel, and the support assembly seals the air inlet of the air outlet connecting channel. When the support assembly is in the air outlet position, the air outlet channel is connected to the air outlet connecting channel, and the support assembly seals the air outlet of the air inlet connecting channel.
[0019] Furthermore, when the support assembly is in its initial position, the support assembly seals the exhaust and intake communication channels respectively.
[0020] Furthermore, the air intake channel includes a first air intake section and a first air outlet section that are interconnected.

[0021] Furthermore, the first intake section and / or the second exhaust section extend radially along the moving scroll; and / or the first exhaust section and / or the second intake section extend axially along the moving scroll.
[0022] Furthermore, there are multiple intake connecting channels, multiple exhaust connecting channels, multiple intake channels, and multiple exhaust connecting channels correspond one-to-one with multiple exhaust channels.
[0023] Furthermore, the support assembly includes: a support member having an air inlet position, an air outlet position, and an initial position; and a reset member abutting between the first bracket and the support member to provide a force for holding the support member in the initial position.

The first bracket and the stationary scroll form a receiving cavity; the moving scroll and the support assembly are both disposed within the receiving cavity, and at least a portion of the support assembly can provide a force to the moving scroll towards the stationary scroll under the action of the fluid within the receiving cavity.
[0027] When using the compressor of this application, because the compressor has a support assembly, and this support assembly can provide a force to the moving scroll towards the stationary scroll under the action of the fluid in the receiving cavity between the stationary scroll and the first bracket, when the moving scroll overturns due to insufficient back pressure, the moving scroll can move towards the stationary scroll under the action of the support assembly, thereby restoring the moving scroll and the stationary scroll to contact each other again. This effectively prevents leakage due to the overturning of the moving scroll, improves the energy efficiency of the compressor, and also avoids the reliability risks caused by the overturning of the moving scroll, thus improving the reliability of the compressor. Therefore, the compressor of this application effectively solves the problem of poor compressor performance in the prior art. Attached Figure Description

[0039] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0040] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0041] In this invention, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.
[0042] To address the problem of poor performance of compressors in the prior art, this application provides a compressor and a heat exchange device.
[0043] Furthermore, the heat exchange device in this application has the compressor described below. Additionally, the heat exchange device in this application can be an air conditioner.
[0044] like Figures 1 to 8 As shown, the compressor in this application includes a first bracket 10, a stationary scroll 20, a moving scroll 40, and a support assembly 50. The first bracket 10 and the stationary scroll 20 form a receiving cavity 30; the moving scroll 40 and the support assembly 50 are both disposed within the receiving cavity 30, and at least a portion of the support assembly 50 can provide a force to the moving scroll 40 towards the stationary scroll 20 under the action of the fluid within the receiving cavity 30.
[0045] When using the compressor of this application, because the compressor has a support assembly 50, and the support assembly 50 can provide a force to the moving scroll 40 towards the stationary scroll 20 under the action of the fluid in the receiving cavity 30 between the stationary scroll 20 and the first bracket 10, when the moving scroll 40 overturns due to insufficient back pressure, the moving scroll 40 can move towards the stationary scroll 20 under the action of the support assembly 50, thereby restoring the moving scroll 40 and the stationary scroll 20 to fit together again. This effectively prevents the moving scroll 40 from overturning and leaking, improves the energy efficiency of the compressor, and also avoids the reliability risks caused by the overturning of the moving scroll 40, thus improving the reliability of the compressor. Therefore, the compressor of this application effectively solves the problem of poor performance of compressors in the prior art.
[0046] Of course, in this application, the compressor mainly consists of a motor, a first bracket 10, a second bracket 100, a stationary scroll 20, a moving scroll 40, a cross slip ring 400, and a crankshaft 300. The motor is fixed to the housing 90 by a heat-shrink fitting, and the first bracket 10 is fixed to the housing 90 by spot welding. Furthermore, the motor includes a motor stator 70 and a motor rotor 80. The moving scroll 40 and the stationary scroll 20 are mounted opposite each other on the first bracket 10 with a phase angle difference of 180 degrees. The moving scroll 40 moves under the drive of the crankshaft 300, meshing with the stationary scroll 20 to form a series of mutually isolated crescent-shaped sealed cavities with continuously changing volumes. The stationary scroll 20 is fixed to the first bracket 10 by screw fasteners. The second bracket 100 is fixed to the lower support ring 200 by screws, and the lower support ring 200 is then fixed to the housing 90 by spot welding.
[0047] When the compressor is running, the motor drives the crankshaft 300 to rotate. The crank of the crankshaft 300 drives the moving scroll 40 to move. Under the anti-rotation restriction of the cross slip ring 400, the moving scroll 40 performs translational motion around the center of the crankshaft 300 with a fixed radius e. The refrigerant entering from the suction pipe is drawn into the crescent-shaped suction chamber formed by the moving scroll 40 and the stationary scroll 20. After being compressed, it is discharged from the exhaust port of the stationary scroll 20 and enters the cavity between the upper cover 500 and the stationary scroll 20. Then, it enters the cavity between the first support 10 and the motor through the exhaust groove of the stationary scroll 20 and the first support 10. Part of it enters the lower end of the motor through the flow groove between the motor and the housing 90. Finally, the high-pressure exhaust refrigerant is discharged through the exhaust pipe.
[0048] Optionally, the first support 10, the stationary scroll 20, the moving scroll 40, and the support assembly 50 satisfy at least one of the following: the moving scroll 40 is spaced apart from the first support 10; the support assembly 50 is located between the moving scroll 40 and the first support 10; and the support assembly 50 is located on the side of the moving scroll 40 away from the stationary scroll 20.
[0049] Optionally, the support assembly 50 is movably disposed within the receiving cavity 30 and has an air inlet position and an air outlet position. When the support assembly 50 moves from the air inlet position to the air outlet position, the support assembly 50 provides a force to the moving scroll 40 towards the stationary scroll 20; when the support assembly 50 moves from the air inlet position to the air outlet position, the support assembly 50 moves in a direction closer to the stationary scroll 20. Furthermore, in this application, the support assembly 50 also has an initial position, and the moving scroll 40 provides a force to the support assembly 50 to move from the initial position to the air inlet position.
[0050] Optionally, the initial position is located between the air intake position and the air outlet position. Furthermore, when the support assembly 50 is in the initial position, there is a movement gap between the support assembly 50 and the moving scroll 40.
[0051] In other words, in this application, the outlet position is located above the inlet position in the axial direction of the compressor, while the initial position is between the inlet and outlet positions. Therefore, when the moving scroll 40 does not overturn or deflects away from the stationary scroll 20, the moving scroll 40 is not in contact with the support assembly 50. At this time, there is no interaction force between the support assembly 50 and the moving scroll 40, or in other words, the moving scroll 40 does not press down on the support assembly 50, and the support assembly 50 does not provide a force for the moving scroll 40 to move towards the stationary scroll 20. However, when the moving scroll 40 overturns or deflects away from the stationary scroll 20, the moving scroll 40 compresses the support assembly 50, thereby enabling the support assembly 50 to move from the initial position to the inlet position. After the support assembly 50 moves to the inlet position, the support assembly 50 can provide a force for the moving scroll 40 to move towards the stationary scroll 20.
[0052] Optionally, the first bracket 10 is provided with a first mounting groove 11 corresponding to the support assembly 50. The opening of the first mounting groove 11 faces the moving scroll 40, and at least a portion of the support assembly 50 is disposed inside the first mounting groove 11. The design of the first mounting groove 11 not only provides positioning and guidance for the support assembly 50, but also ensures that the support assembly 50 can move smoothly under the action of fluid, providing necessary support for the moving scroll 40. Therefore, this arrangement improves the stability and reliability of the support assembly 50 and ensures a good seal between the moving scroll 40 and the stationary scroll 20.
[0053] Optionally, when the support assembly 50 is in the air intake position, at least a portion of the support assembly 50 is located outside the first mounting groove 11. Optionally, when the support assembly 50 is in the air outlet position, at least a portion of the support assembly 50 is located outside the first mounting groove 11. This arrangement ensures that when the moving scroll 40 overturns, it can more easily compress the support assembly 50, thereby ensuring that the support assembly 50 can move to the air intake position in a timely manner and provide the moving scroll 40 with a force that propels it toward the stationary scroll 20.
[0054] Optionally, the receiving cavity 30 is divided into a first air chamber 31 and a second air chamber 32 in the radial direction of the receiving cavity 30, with the first mounting groove 11 as the boundary. The second air chamber 32 is located on the outer periphery of the first air chamber 31, and the pressure of the first air chamber 31 is greater than the pressure of the second air chamber 32. The support assembly 50 is movably disposed in the first mounting groove 11 so that the first air chamber 31 and the second air chamber 32 are respectively in openable and closable communication with the interior of the first mounting groove 11.
[0055] Specifically, a gas transition area is formed between the support assembly 50 and the bottom of the first mounting groove 11. The support assembly 50 has an air inlet channel 51 and an air outlet channel 52, with the outlet end of the air inlet channel 51 and the inlet end of the air outlet channel 52 respectively connected to the gas transition area. When the support assembly 50 is in the air inlet position, the pressure at the air inlet end of the air inlet channel 51 is P1; when the support assembly 50 is in the air outlet position, the pressure at the air outlet end of the air outlet channel 52 is P2; P1>P2. This arrangement ensures that when the support assembly 50 is in the air inlet position, the gas in the first air chamber 31 can more easily enter the interior of the first mounting groove 11 and provide the support assembly 50 with the force to push the moving scroll 40 toward the stationary scroll 20. When the support assembly 50 moves to the air outlet position, it ensures that the gas in the first mounting groove 11 can be more easily discharged to the second air chamber 32.
[0056] Specifically, the support assembly 50 includes a support member 53 and a reset member 54. The support member 53 has an air inlet position, an air outlet position, and an initial position. The reset member 54 abuts between the first bracket 10 and the support member 53 to provide a force for holding the support member 53 in the initial position. Furthermore, in this application, the reset member 54 can be a wave spring. Also, in this application, the support member 53 has an air inlet channel 51 and an air outlet channel 52.
[0057] Optionally, the first bracket 10 is provided with a groove structure 111 corresponding to the reset member 54, and at least a portion of the reset member 54 is disposed within the groove structure 111. This arrangement allows the reset member 54 to be reset through the groove structure 111, thereby ensuring the stability of the action of the reset member 54 on the support member 53, and ensuring that the support member 53 is subjected to more stable forces.
[0058] Optionally, a groove structure 111 is formed at the bottom of the first mounting groove 11, and the groove structure 111 forms at least a portion of the gas transition region. Since the space between the support member 53 of the support assembly 50 and the bottom of the first mounting groove 11 changes when gas enters or exits the first mounting groove 11, this change is formed by gas entering the first mounting groove 11 from the first air chamber 31 or gas exiting the first mounting groove 11 to the second air chamber 32. Therefore, in this application, the size of the transition region changes with the movement of the support member 53 of the support assembly 50; that is, when the support assembly 50 moves from the air inlet position to the air outlet position, the space of the transition region increases. However, it should be noted that in this application, since the groove structure 111 is also used to place the reset member 54, the size of the groove structure 111 remains constant.
[0059] Optionally, the first mounting groove 11 has a first annular sidewall 112 and a second annular sidewall 113 arranged radially at intervals along the moving scroll 40. The first annular sidewall 112 is closer to the axis of the moving scroll 40 than the second annular sidewall 113. The first air chamber 31 communicates with the interior of the first mounting groove 11 through the first annular sidewall 112, and the second air chamber 32 communicates with the interior of the first mounting groove 11 through the second annular sidewall 113.
[0060] Optionally, at least one of the first annular sidewall 112 and the second annular sidewall 113 has a second mounting groove 114 on the side facing the moving scroll 40, and the compressor further includes a sealing assembly 60, at least a portion of which is disposed in the second mounting groove 114 and abuts against the moving scroll 40.
[0061] It should be noted that in this application, the second mounting groove 114 is an annular mounting groove. By ensuring that the sealing component 60 is always located within the second mounting groove 114 and always in contact with the moving scroll plate 40, it can be guaranteed that the first air chamber 31 and the second air chamber 32 can only communicate through the first mounting groove 11, and not through the gap between the moving scroll plate 40 and the top surface of the first mounting groove 11, thereby ensuring the normal operation of the support component 50 in this application. Furthermore, the second mounting groove 114 can be located on the first annular sidewall 112 or on the second annular sidewall 113, and both the first annular sidewall 112 and the second annular sidewall 113 can also be equipped with the sealing component 60, as long as it can prevent the first air chamber 31 and the second air chamber 32 from communicating through other locations.
[0062] In this application, the sealing assembly 60 may consist of only one sealing ring, made of a deformable material, to ensure that the sealing ring always abuts against the side of the moving scroll 40 away from the stationary scroll 20 as the moving scroll 40 moves. Alternatively, the sealing assembly 60 may include a spring or spring plate as a reset structure, with the spring or spring plate positioned on the side of the sealing ring away from the moving scroll 40, ensuring that the sealing ring always abuts against the moving scroll 40 under the action of the spring or spring plate. Furthermore, in this application, the spring and spring plate are always located within the second mounting groove 114, but to ensure that the sealing ring always abuts against the moving scroll 40, the side of the sealing ring away from the spring or spring plate can be designed to extend out of the second mounting groove 114.
[0063] Specifically, the first annular sidewall 112 has at least one air inlet communication channel 1121, and the first air chamber 31 is connected to the interior of the first mounting groove 11 through the air inlet communication channel 1121; the second annular sidewall 113 has at least one air outlet communication channel 1131, and the second air chamber 32 is connected to the interior of the first mounting groove 11 through the air outlet communication channel 1131.
[0064] Specifically, the support assembly 50 has at least one air inlet channel 51 and at least one air outlet channel 52. When the support assembly 50 is in the air inlet position, the air inlet channel 51 is connected to the air inlet communication channel 1121, and the support assembly 50 seals the air inlet of the air outlet communication channel 1131. When the support assembly 50 is in the air outlet position, the air outlet channel 52 is connected to the air outlet communication channel 1131, and the support assembly 50 seals the air outlet of the air inlet communication channel 1121.
[0065] Specifically, when the support assembly 50 is in its initial position, it seals the air outlet communication channel 1131 and the air inlet communication channel 1121 respectively. Therefore, at this time, the interior of the first mounting groove 11 is not connected to the first air chamber 31 and the second air chamber 32.
[0066] Specifically, the air intake channel 51 includes a first air intake section 511 and a first air outlet section 512 that are interconnected. The end of the first air intake section 511 away from the first air outlet section 512 can be connected to the air intake communication channel 1121. The end of the first air outlet section 512 away from the first air intake section 511 faces the bottom surface of the first mounting groove 11 and is disposed through the support component 50. The air outlet channel 52 includes a second air intake section 521 and a second air outlet section 522 that are interconnected. The end of the second air outlet section 522 away from the second air intake section 521 can be connected to the air outlet communication channel 1131. The end of the second air intake section 521 away from the second air outlet section 522 faces the bottom surface of the first mounting groove 11 and is disposed through the support component 50.
[0067] Preferably, the first intake section 511 and / or the second exhaust section 522 extend radially along the moving scroll 40.
[0068] Preferably, the first exhaust section 512 and / or the second intake section 521 extend along the axial direction of the moving scroll 40.
[0069] Optionally, there are multiple air inlet channels 1121, air outlet channels 1131, air inlet channels 51, and air outlet channels 52. Each air inlet channel 1121 corresponds to one air inlet channel 51, and each air outlet channel 1131 corresponds to one air outlet channel 52. This arrangement ensures that gas within the receiving cavity 30 can more easily enter or exit the first mounting slot 11, thereby guaranteeing the performance of the support assembly 50.
[0070] When using the compressor of this application, during the operation of the compressor, for some light loads, the moving scroll 40 may detach from the stationary scroll 20 and overturn due to insufficient back pressure. The back of the moving scroll 40 presses against the upper end of the support member 53, causing the support member 53 to move downwards and toward the intake position. Figure 4 and Figure 5 As shown, at this time, the air intake channel 51 of the support member 53 is connected to the air intake communication channel 1121 of the first annular sidewall 112, so the high-pressure exhaust in the first air chamber 31 enters the first mounting groove 11 through this channel. Under the action of high pressure, the support member 53 pushes the back of the moving scroll 40 upward to fit tightly against the stationary scroll 20, thereby suppressing the leakage problem caused by the overturning of the moving scroll 40 and ensuring energy efficiency under light load conditions. Figure 6 and Figure 7 As shown, when the support member 53 pushes the back of the moving scroll 40 upward to a state of close contact with the stationary scroll 20, the support assembly 50 is in the air outlet position, and at this time the air outlet channel 52 of the support member 53 is connected to the air outlet communication channel 1131 of the second annular sidewall 113. The high pressure in the first mounting groove 11 gradually releases pressure to the second air chamber 32 through this channel, causing the high pressure in the groove structure 111 of the first mounting groove 11 to slowly release until the pressure in the first receiving groove and the second air chamber 32 are equal. Afterwards, as... Figure 2 and Figure 3 As shown, the support member 53 moves down to its initial position under its own gravity. At this time, the support member 53 is separated from the back of the moving vortex disk 40, and the first mounting groove 11 is not connected to the first air chamber 31 and the second air chamber 32.
[0071] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:
[0072] 1. Effectively solves the problem of poor compressor performance in existing technologies;
[0073] 2. Simple structure and stable performance.
