[0039] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the 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 ordinary technicians in the technical field to which this application belongs.

[0041] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0042] In order to solve the problem of poor performance of compressors in the prior art, the present application provides a compressor and a heat exchange device.

[0043] Furthermore, the heat exchange device in the present application has the following compressor. In addition, the heat exchange device in the present application may be an air conditioner.

[0044] like Figures 1 to 8 As shown, the compressor of the present application includes a first bracket 10, a fixed scroll 20, an orbiting scroll 40, and a support assembly 50. The first bracket 10 and the fixed scroll 20 enclose an accommodating chamber 30; the orbiting scroll 40 and the support assembly 50 are both disposed within the accommodating chamber 30, and at least a portion of the support assembly 50 is capable of providing a force for the orbiting scroll 40 to move toward the fixed scroll 20 under the action of the fluid within the accommodating chamber 30.

[0045] When using the compressor of the present application, since the compressor has a support assembly 50, and the support assembly 50 can provide the movable scroll 40 with a force to move toward the fixed scroll 20 under the action of the fluid in the accommodating chamber 30 between the fixed scroll 20 and the first bracket 10, when the movable scroll 40 overturns due to insufficient back pressure, the movable scroll 40 can move toward the fixed scroll 20 under the action of the support assembly 50, so that the movable scroll 40 and the fixed scroll 20 can be restored to fit, thereby effectively preventing the movable scroll 40 from overturning and leaking, improving the energy efficiency of the compressor, and also avoiding the reliability risk caused by the overturning of the movable scroll 40, thereby improving the reliability of the compressor. Therefore, the compressor of the present application effectively solves the problem of poor performance of compressors in the prior art.

[0046] Of course, in the present application, the compressor is mainly composed of a motor, a first bracket 10, a second bracket 100, a fixed scroll 20, a movable scroll 40, a cross ring 400, a crankshaft 300, etc. The motor is fixed to the housing 90 by shrink fitting, and the first bracket 10 is fixed to the housing 90 by spot welding. In addition, the motor includes a motor stator 70 and a motor rotor 80. The movable scroll 40 and the fixed scroll 20 are mounted on the first bracket 10 with a phase angle difference of 180 degrees. The movable scroll 40 moves under the drive of the crankshaft 300 and engages with the fixed scroll 20 to form a series of crescent-shaped closed cavities that are isolated from each other and have continuously changing volumes. The fixed 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 fixed to the housing 90 by spot welding.

[0047] When the compressor is running, the motor drives the crankshaft 300 to rotate, and the crank of the crankshaft 300 drives the orbiting scroll 40 to move. Under the anti-rotation restriction of the cross ring 400, the orbiting scroll 40 performs translational motion around the center of the crankshaft 300 at a fixed radius e. Refrigerant entering through the intake pipe is drawn into the crescent-shaped intake chamber formed by the orbiting scroll 40 and the fixed scroll 20. After compression, it is discharged through the exhaust hole of the fixed scroll 20 and enters the chamber between the upper cover 500 and the fixed scroll 20. It then enters the chamber between the first bracket 10 and the motor through the exhaust groove between the fixed scroll 20 and the first bracket 10. Some 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 bracket 10, the fixed scroll 20, the movable scroll 40 and the support assembly 50 satisfy at least one of the following: the movable scroll 40 is spaced apart from the first bracket 10; the support assembly 50 is located between the movable scroll 40 and the first bracket 10; the support assembly 50 is located on the side of the movable scroll 40 away from the fixed scroll 20.

[0049] Optionally, the support assembly 50 is movably disposed within the accommodating chamber 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 for the orbiting scroll 40 to move toward the fixed 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 approaching the fixed scroll 20. In addition, in the present application, the support assembly 50 also has an initial position, and the orbiting scroll 40 provides a force for 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 inlet position and the air outlet position. In addition, when the support assembly 50 is at the initial position, there is a movement gap between the support assembly 50 and the movable scroll 40 .

[0051] That is to say, in the present application, in the axial direction of the compressor, the outlet position is located above the inlet position, and the initial position is between the inlet position and the outlet position. Therefore, when the movable scroll 40 does not overturn or when the movable scroll 40 does not deflect in a direction away from the fixed scroll 20, the movable scroll 40 does not contact the support assembly 50. At this time, there is no interaction force between the support assembly 50 and the movable scroll 40, or in other words, the movable scroll 40 does not press down the support assembly 50 and the support assembly 50 does not provide the movable scroll 40 with a force to move toward the fixed scroll 20. When the movable scroll 40 overturns or when the movable scroll 40 deflects in a direction away from the fixed scroll 20, the movable scroll 40 squeezes the support assembly 50, so that the support assembly 50 can move from the initial position to the inlet position, and after the support assembly 50 moves to the inlet position, the support assembly 50 can provide the movable scroll 40 with a force to move toward the fixed 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 is disposed toward the orbiting scroll 40, and at least a portion of the support assembly 50 is disposed within 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 smooth movement of the support assembly 50 under the action of the fluid, providing the necessary support for the orbiting scroll 40. This arrangement thus improves the stability and reliability of the support assembly 50 and ensures a good seal between the orbiting scroll 40 and the fixed scroll 20.

[0053] Optionally, when the support assembly 50 is in the 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 exhaust position, at least a portion of the support assembly 50 is located outside the first mounting groove 11. This arrangement ensures that when the orbiting scroll 40 overturns, the orbiting scroll 40 can more easily squeeze the support assembly 50, thereby ensuring that the support assembly 50 can move to the intake position in a timely manner and provide the orbiting scroll 40 with a force to move toward the fixed scroll 20.

[0054] Optionally, the accommodating cavity 30 is divided into a first air cavity 31 and a second air cavity 32 with the first mounting groove 11 as the dividing line in the radial direction of the accommodating cavity 30. The second air cavity 32 is located on the outer peripheral side of the first air cavity 31, and the pressure of the first air cavity 31 is greater than the pressure of the second air cavity 32. The support assembly 50 is movably arranged in the first mounting groove 11 so that the first air cavity 31 and the second air cavity 32 are respectively connected to the interior of the first mounting groove 11 in an openable and closable manner.

[0055] Specifically, a gas transition region is formed between the support assembly 50 and the bottom of the first mounting groove 11. The support assembly 50 has an inlet channel 51 and an outlet channel 52. The outlet end of the inlet channel 51 and the inlet end of the outlet channel 52 are respectively connected to the gas transition region. When the support assembly 50 is in the inlet position, the pressure at the inlet end of the inlet channel 51 is P1; when the support assembly 50 is in the outlet position, the pressure at the outlet end of the outlet channel 52 is P2; P1>P2. This arrangement ensures that when the support assembly 50 is in the inlet position, the gas within the first air cavity 31 can more easily enter the interior of the first mounting groove 11 and provide the support assembly 50 with a force to propel the orbiting scroll 40 toward the fixed scroll 20. When the support assembly 50 moves to the outlet position, the gas within the first mounting groove 11 can more easily be discharged into the second air cavity 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 to maintain the support member 53 in the initial position. Furthermore, in the present application, the reset member 54 can be a wave spring. Furthermore, in the present 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 reset member 54 acting on the support member 53, thereby ensuring that the force applied to the support member 53 is more stable.

[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 area. Since the space between the support member 53 of the support assembly 50 and the bottom of the first mounting groove 11 changes when the gas enters or exits the first mounting groove 11, and this change is caused by the gas in the first air cavity 31 entering the first mounting groove 11, or the gas in the first mounting groove 11 being discharged into the second air cavity 32, the spatial size of the transition area in the present application 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 area becomes larger. However, it should be noted that in the present application, since the groove structure 111 is also used to place the reset member 54, the spatial size of the groove structure 111 remains unchanged.

[0059] Optionally, the first mounting groove 11 has a first annular side wall 112 and a second annular side wall 113 arranged at intervals along the radial direction of the movable scroll 40, the first annular side wall 112 is close to the axis of the movable scroll 40 relative to the second annular side wall 113, the first air cavity 31 is connected to the interior of the first mounting groove 11 through the first annular side wall 112, and the second air cavity 32 is connected to the interior of the first mounting groove 11 through the second annular side wall 113.

[0060] Optionally, at least one of the first annular side wall 112 and the second annular side wall 113 has a second mounting groove 114 on the side facing the movable scroll 40, and the compressor also includes a sealing assembly 60, at least a portion of the sealing assembly 60 is arranged in the second mounting groove 114, and the sealing assembly 60 abuts against the movable scroll 40.

[0061] It should be noted that in the present application, the second mounting groove 114 is an annular mounting groove, and by ensuring that the sealing assembly 60 is always located in the second mounting groove 114 and always in contact with the orbiting scroll 40, it is possible to ensure that the first air cavity 31 and the second air cavity 32 can only communicate through the first mounting groove 11, and not through the gap between the orbiting scroll 40 and the top surface of the first mounting groove 11, thereby ensuring the normal operation of the support assembly 50 in the present application. In addition, with respect to the location of the second mounting groove 114, it can be set on the first annular sidewall 112 or on the second annular sidewall 113, and the sealing assembly 60 can also be provided on both the first annular sidewall 112 and the second annular sidewall 113, as long as the first air cavity 31 and the second air cavity 32 are prevented from communicating through other locations.

[0062] In the present application, the sealing assembly 60 may include only one sealing ring, and in this case, the sealing ring is made of a deformable material, thereby ensuring that as the orbiting scroll 40 moves, the sealing ring can always abut against the side of the orbiting scroll 40 away from the fixed scroll 20. Of course, in the present application, the sealing assembly 60 may also include a reset structure such as a spring or a spring plate, and the spring or spring plate is provided on the side of the sealing ring away from the orbiting scroll 40, thereby ensuring that the sealing ring can always abut against the orbiting scroll 40 under the action of the spring or spring plate. Moreover, in the present application, the spring and spring plate will always be located in the second mounting groove 114. In order to ensure that the sealing ring always abuts against the orbiting 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 side wall 112 has at least one air inlet communicating channel 1121, and the first air cavity 31 is connected to the interior of the first mounting groove 11 through the air inlet communicating channel 1121; the second annular side wall 113 has at least one air outlet communicating channel 1131, and the second air cavity 32 is connected to the interior of the first mounting groove 11 through the air outlet communicating 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 with the air inlet connecting channel 1121, and the support assembly 50 seals the air inlet of the air outlet connecting channel 1131; when the support assembly 50 is in the air outlet position, the air outlet channel 52 is connected with the air outlet connecting channel 1131, and the support assembly 50 seals the air outlet of the air inlet connecting channel 1121.

[0065] Specifically, when the support assembly 50 is in the initial position, the support assembly 50 seals the outlet communication channel 1131 and the inlet communication channel 1121. Therefore, the interior of the first mounting groove 11 is not connected to the first air cavity 31 and the second air cavity 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, and the end of the first air intake section 511 away from the first air outlet section 512 can be connected to the air intake connecting channel 1121, and the end of the first air outlet section 512 away from the first air intake section 511 is toward the bottom surface of the first mounting groove 11 and passes through the support assembly 50; the air outlet channel 52 includes a second air intake section 521 and a second air outlet section 522 that are interconnected, and the end of the second air outlet section 522 away from the second air intake section 521 can be connected to the air outlet connecting channel 1131, and the end of the second air intake section 521 away from the second air outlet section 522 is toward the bottom surface of the first mounting groove 11 and passes through the support assembly 50.

[0067] Preferably, the first air inlet section 511 and / or the second air outlet section 522 extend in the radial direction of the orbiting scroll 40 .

[0068] Preferably, the first air outlet section 512 and / or the second air inlet section 521 extend along the axial direction of the orbiting scroll 40 .

[0069] Optionally, there are multiple inlet communication channels 1121, outlet communication channels 1131, inlet channels 51, and outlet channels 52, with the multiple inlet communication channels 1121 corresponding one-to-one to the multiple inlet channels 51, and the multiple outlet communication channels 1131 corresponding one-to-one to the multiple outlet channels 52. This arrangement ensures that the gas in the accommodating cavity 30 can more easily enter or exit the first mounting groove 11, thereby ensuring the performance of the support assembly 50.

[0070] When the compressor of the present application is used, during the operation of the compressor, for some light-load operations, the movable scroll 40 is separated from the stationary scroll 20 due to insufficient back pressure, and the movable scroll 40 overturns. The back of the movable scroll 40 presses on the upper end of the support member 53, causing the support member 53 to move downward and toward the air intake position. Figure 4 and Figure 5 As shown, at this time, the air inlet channel 51 of the support member 53 is connected to the air inlet communication channel 1121 of the first annular side wall 112, and the high-pressure exhaust gas in the first air cavity 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 orbiting scroll 40 upward to fit tightly with the fixed scroll 20, thereby suppressing the leakage problem caused by the overturning of the orbiting scroll 40 and ensuring the energy efficiency under light load conditions. Figure 6 and Figure 7 As shown, when the support member 53 pushes the back of the orbiting scroll 40 upward to a state of close contact with the fixed scroll 20, the support assembly 50 is in the air outlet position, and the air outlet channel 52 of the support member 53 is connected to the air outlet communication channel 1131 of the second annular side wall 113. Then, the high pressure in the first mounting groove 11 is gradually released to the second air cavity 32 through this channel, so that the high pressure in the groove structure 111 of the first mounting groove 11 is slowly released until the pressure in the first receiving groove and the second air cavity 32 are equal. Afterwards, as shown in FIG. Figure 2 and Figure 3 As shown, the support member 53 moves downward to the initial position under the action of its own gravity. At this time, the support member 53 is separated from the back of the movable scroll 40, and the first installation groove 11 is not connected to the first air cavity 31 and the second air cavity 32.

[0071] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0072] 1. Effectively solve the problem of poor performance of compressors in the existing technology;

[0073] 2. Simple structure and stable performance.

[0074] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of the embodiments.
