[0046] The present invention also provides an air conditioner, comprising the compressor as described in any of the preceding items.

[0047] Provided are an upper bracket lubricating oil circuit system with a cooling function and a scroll compressor having the same. The lubricating oil circuit system can effectively improve the lubrication effect of a pump body and enhance the reliability of the compressor.

[0048] like Figure 1 As shown, the scroll compressor is mainly composed of a motor 6, a bracket 4, a lower bracket 10, a stator 2, a moving disc 16, a cross slip ring 3, a crankshaft 7, etc. The motor 6 is fixed to the housing 12 by a shrink sleeve, and the bracket 4 is fixed to the housing 12 by eight-point welding. The moving disc 16 and the stator 2 are installed on the bracket 4 opposite to each other with a phase angle difference of 180 degrees. The moving disc 16 moves under the drive of the crankshaft 7 and meshes with the stator 2 to form a series of crescent-shaped closed cavities that are isolated from each other and have continuously changing volumes. The stator 2 is fixed to the upper bracket 4 by screw fasteners. The crankshaft assembly is axially thrust-stopped by a thrust plate 18, which is fixed to the lower bracket 10 by screws, and the lower bracket 10 is fixed to the lower support ring 8 by screws, and the lower support ring 8 is fixed to the housing 12 by spot welding.

[0049] When the compressor is running, the motor 6 drives the crankshaft 7 to rotate, and the crank of the crankshaft 7 drives the moving plate 16 to move. Under the anti-rotation limit of the cross slip ring 3, the moving plate 16 performs translational motion around the center of the crankshaft 7 at a fixed radius. The refrigerant entering from the suction pipe 17 is sucked into the crescent-shaped suction cavity formed by the moving plate 16 and the static plate 2, and is discharged from the exhaust hole of the static plate 2 after being compressed, and enters the cavity between the upper cover 1 and the static plate 2, and then enters the cavity between the bracket 4 and the motor 6 through the exhaust groove of the static plate 2 and the bracket 4, and partially enters the lower end of the motor 6 through the flow groove between the motor 6 and the housing 12, and finally the high-pressure exhaust refrigerant is discharged through the exhaust pipe.

[0050] like Figure 2 The oil circuit structure diagram of the upper bracket bearing of the present invention is shown in FIG. The bearing seat end of the bracket 4 is provided with a fourth oil groove 401 and an annular groove 407. The fourth oil groove 401 connects the upper bracket oil pool 19 and the annular groove 407 to lubricate the lower end of the sliding bearing 20. The fifth oil groove 402 and the sixth oil groove 403 are connected to the annular groove 407. The fifth oil groove 402 and the sixth oil groove 403 are connected to the seventh oil groove 404 through the oil delivery pipe 13. A throttle valve 14 is installed at the upper end of the oil delivery pipe 13.

[0051] like Figure 3 The first oil groove 201, the second oil groove 202 and the third oil groove 203 are provided around the air inlet 21 of the stator plate 2. The oil grooves are connected to the first transition oil groove 405, the second transition oil groove 406 and the seventh oil groove 404 respectively. The first transition oil groove 405 and the second transition oil groove 406 are connected to the back pressure chamber 15. For details, see Figure 4 , Figure 5 .

[0052] When the scroll compressor is working, the lubricating oil of the high pressure Pd in ​​the oil pool 19 of the upper bracket enters the annular groove 407 through the fourth oil groove 401 to lubricate the lower end of the sliding bearing 20. The lubricating oil in the annular groove 407 is then supplied to the stator plate 2 through the fifth oil groove 402, the sixth oil groove 403, the oil delivery pipe 13, the throttle valve 14 and the seventh oil groove 404. The throttle valve 14 can prevent the compressor from having excessive oil when the compressor is running at high speed. The first oil groove 201, the second oil groove 202 and the third oil groove 203 of the stator plate 2 are cooled by low-temperature suction air to reduce the temperature of the lubricating oil and increase the viscosity of the lubricating oil. The cooled lubricating oil is then supplied to the back pressure cavity 15 of the medium pressure Pm through the first transition oil groove 405 and the second transition oil groove 406 of the bracket 4 to improve the reliability of lubrication of the dynamic and static plates. Because the pressure Pd in ​​the upper bracket oil pool 19 is greater than the medium pressure Pm in the back pressure chamber 15, this pressure difference will accelerate the oil circulation from the upper bracket oil pool 19 to the back pressure chamber 15, and the throttle valve 14 can prevent excessive oil supply.

Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above description is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention.
