Description

Technical Field

[0001] The present invention relates to the field of scroll air-conditioning compressors, and more particularly to a self-cleaning scroll air-conditioning compressor. Background Art

[0002] A scroll compressor is a compressible compressor consisting of a fixed involute scroll and an eccentrically rotating, swirling involute scroll. A scroll compressor is composed of two interlocking orbiting and stationary scrolls with dual-function equation profiles. During the suction, compression, and exhaust processes, the stationary disk is fixed to the frame, while the moving disk is driven by an eccentric shaft and restrained by an anti-rotation mechanism, rotating in a plane with a very small radius around the center of the stationary disk's base circle. Gas is drawn into the periphery of the stationary disk through an air filter. As the eccentric shaft rotates, the gas is gradually compressed within the crescent-shaped compression chambers formed by the interlocking orbiting and stationary disks, and then continuously discharged through the axial hole in the center of the stationary disk.

[0003] Since the movable and static vortex plates engage with each other, the suction, compression and exhaust processes can be carried out. If dust enters the movable and static vortex plates, it will affect the degree of engagement between the movable and static vortex plates, and thus greatly reduce the suction, compression and exhaust efficiency. In order to prevent dust from entering the movable and static vortex plates, the existing technology is to pass the air through a filter to filter the dust. However, the filter screen does not have a self-cleaning function, so it will affect the dust filtering effect and the air intake effect after long-term use. Summary of the Invention

[0004] In response to the problems existing in the prior art, the purpose of the present invention is to provide a self-cleaning scroll air-conditioning compressor, which can prevent dust from entering the compressor and has a self-cleaning function, which can continuously ensure the cleanliness of the movable and stationary scrolls in the compressor and improve long-term working efficiency.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0006] A self-cleaning scroll air-conditioning compressor includes a shell, which is constructed as a tank structure with an air inlet and an air outlet; a compressor body is provided in the shell, and the compressor body is used to allow air to enter the shell along the air inlet and be discharged outward from the air outlet; a self-cleaning component is provided at the air inlet; the self-cleaning component includes: an air inlet box body, which is connected to the air inlet; a notch is provided on the air inlet box body; a filter element is installed in the notch, and the filter element has at least an air inlet port, an air inlet channel and one or more filter surfaces; a plurality of filter holes are provided on the filter surface to form a filter area, so that the air enters the air inlet channel from the air inlet port and then passes through the filter surface along the air inlet direction to reach the air inlet; a sealing element is provided in the air inlet box body, and the sealing element is used to seal part or multiple filter surfaces that are different from the air inlet direction; a driving element is provided at the filter element, and the driving element is used to drive the filter element to rotate around a fixed axis.

[0007] The gas enters from one end face of the filter element and is then discharged from the side. One end face of the filter element is sealed, and the other end face is connected to the air inlet. Then the gas will not be discharged outward through the entire filter surface, but only through part of the filter surface. The driving member will also drive the filter element to rotate, so that the filter surface on the filter element will filter the air at different positions, which will make the filter element filter more evenly, avoiding serious dust accumulation in one place of the filter element, affecting the speed of air passing through, thereby better ensuring the effect of air filtering. At the same time, since the filter element will rotate under the action of the driving member, the dust inside the filter element itself will fall down under the action of rotational inertia, realizing the self-cleaning function.

[0008] Furthermore, the sealing member includes: a first stopper and a second stopper, both of which are fixed to the air intake box; the first stopper, the second stopper, the filter element and the inner wall of the air intake box form a accommodating chamber and an air intake chamber; the accommodating chamber is connected to the air intake channel through the filter surface; the air intake chamber is connected to the air intake channel through the filter surface.

[0009] The space inside the air intake box is divided into a receiving chamber and an air intake chamber by the first stopper and the second stopper, so that the air in the air intake passage can enter either the receiving chamber or the air intake chamber.

[0010] Furthermore, a piston portion is provided in the air intake box, the piston portion is located in the accommodating chamber, and the piston portion is sealed against the inner wall of the air intake box; the piston portion is used to divide the accommodating chamber into a cooling chamber and a cleaning chamber; a pushing portion is installed at one end of the piston portion, and the pushing portion is used to drive the piston portion to move close to the filter element to a first position or away from the filter element to a second position so that both the cleaning chamber and the cooling chamber can be exhausted or inhaled.

[0011] The movement of the piston part can make the gas in the intake channel enter the clean chamber and be drawn in, so the air intake speed is greater than the normal air intake speed, which can speed up the air extraction speed of the compressor body to a certain extent; when the piston part compresses the clean chamber, the air in the clean chamber can be squeezed out, and then the air can be reversed through the filter element to backflushed the dust particles in the filter element, thereby preventing the dust particles from clogging the filter element and better ensuring the filtering effect of the filter element and the ventilation effect of the filter element.

[0012] Furthermore, there is a gap between the first stop portion and the filter element, and there is a gap between the second stop portion and the filter element; the sealing element also includes: a first sealing portion and a second sealing portion, the first sealing portion is arranged on the first stop portion, and the second sealing portion is arranged on the second stop portion; a connecting portion is provided on the piston portion, and the connecting portion is used to transmit the piston portion to the first sealing portion and the second sealing portion respectively; so that when the piston portion moves away from the filter element, the first sealing portion and the second sealing portion move close to the filter element to abut against the filter element and seal tightly.

[0013] When the filter element needs to be backflushed and cleaned, the cleaning chamber is sealed by the first sealing part and the second sealing part, so that the air in the cleaning chamber can only pass through the filtering surface of the filter element under the compression of the piston part, avoiding air leakage, better ensuring the air pressure during backflushing, and thus making the backflushing cleaning effect better.

[0015] By providing the elastic member, the first and second sealing members can be linked to the movement of the piston member, eliminating the need for an internal driver, thereby enabling normal movement of the first and second sealing members. Furthermore, providing a driver inside the air intake housing is difficult to install and wire, and there is insufficient space for installing the driver. The elastic member can then allow the piston member to move a greater distance without affecting the normal sealing of the first and second sealing members, thereby better allowing the cleaning chamber to accommodate more air, thereby achieving a better cleaning effect during backflushing of the filter element.

[0016] Furthermore, a first guide portion is provided on the first stop portion, and a second guide portion is provided on the second stop portion; the first guide portion is used to guide the first sealing portion to move closer to or away from the filter element; the second guide portion is used to guide the second sealing portion to move closer to or away from the sealing element.

[0017] Furthermore, the connecting part is provided with two groups, which are respectively used to connect the first sealing part and the second sealing part with the piston part; one group of connecting parts includes: a flexible rope, one end of the flexible rope is fixedly connected to the elastic part and the other end is fixedly connected to the first sealing part; the first sealing part is provided with a groove, so that the first sealing part has at least a part of its position spaced apart from the first blocking part; a connecting surface is formed on the first sealing part, and the connecting surface is located in the groove; a through hole is provided on the first blocking part so that the flexible rope can pass through the through hole and be connected to the first sealing part, and the flexible rope is fixedly connected to the connecting surface; the distance between the through hole and the filter element is smaller than the distance between the connecting surface and the filter element.

[0019] Furthermore, a mounting portion is provided at the opening of the filter element, and the mounting portion is fixedly connected to the air intake box; a guide surface is formed on the mounting portion, and the guide surface is in contact with the inner surface of the filter element, and is used to guide the rotation of the filter element; a passage groove is provided on the mounting portion, and the passage groove is used to allow air to enter the air intake channel; a protrusion is formed at the passage groove, and the protrusion and the mounting portion are integrally formed, and a filter screen is provided on the protrusion, and the protrusion abuts against the end face of the filter screen, and the side face of the filter screen abuts against the groove surface of the passage groove.

[0043] The gas enters from one end face of the filter element 3 and is then discharged from the side. One end face of the filter element 3 is sealed, and the other end face is connected to the air inlet 11. Then the gas will not be discharged outward through the entire filter surface, but only through part of the filter surface. The driving member 5 will also drive the filter element 3 to rotate, so that the filter surface on the filter element 3 will filter the air at different positions, so that the filter element 3 will filter more evenly, avoiding serious dust accumulation in one place of the filter element 3, affecting the speed of air passing through, thereby better ensuring the effect of filtering the air.

[0044] Furthermore, the sealing member 4 includes a first stopper 41 and a second stopper 42, both of which are fixed to the air intake housing 2.

A second pipe section 581 is disposed within the first pipe section 58 and is slidably connected to the first pipe section 58. A one-way pressure valve 582 is mounted on one end of the second pipe section 581, located within the first pipe section 58. The purpose of the one-way pressure valve 582 is to allow air in the first pipe section 58 to enter the second pipe section 581, while preventing air in the second pipe section 581 from entering the first pipe section 58.

[0070] A locking plate 59 is fixedly mounted on the connecting rod 31. The locking plate 59 is constructed in the shape of a gear and is provided with a locking plate 591.

[0071] A refrigeration tank 597 is provided at the outer shell. The refrigeration tank 597 contains low-temperature gas. The refrigeration tank 597 is connected to the air intake box through the fourth pipe section 598. The fourth pipe section 598 is fixed to the refrigeration tank 597 and the air intake box. The fourth pipe section 598 is located inside the refrigeration chamber.

[0072] Working conditions:

[0073] The driving motor 51 drives the first transmission plate 54 to rotate through the transmission belt 53, and the first transmission plate 54 drives the second transmission plate 55 to rotate and then the connecting rod 31 to rotate, that is, the filter element 3 will rotate; when the piston part 43 moves away from the filter element 3, the first sealing part 45 and the second sealing part 46 will abut and seal with the filter element 3, and the gas in the cooling chamber will reach the first pipe section 58. The gas in the first pipe section 58 pushes the second pipe section 581 away from the first pipe section 58 through the one-way pressure valve 582, and the second pipe section 581 drives the locking plate 591 and the third pipe section 596 to move together. The locking plate 591 is locked in the locking disk 59, thereby preventing the connecting rod 31 from rotating. However, there is no need to stop the driving motor 51 at this time, that is, the second transmission plate 55 will continue to rotate. The continued rotation of the second transmission plate 55 will cause the first arc block and the second arc block to slip, thereby enabling the first transmission plate 54 to be stationary and the second transmission plate 55 to move. The gas in the cooling chamber is blown outward along the first pipe section 58, the second pipe section 581 and the third pipe section 596, and blows onto the positions of the first arc block and the second arc block to cool them down.

[0074] The first transmission plate 54 cannot rotate, but the second transmission plate 55 rotates normally, which causes the first transmission plate 54 to move up and down, the block 541 slides in the slot 311, and the second tension spring 57 causes the second transmission plate 55 to move down and reset, thereby achieving misalignment and slippage.
