Title:

SCROLL COMPRESSOR

Document Type and Number:

WIPO Patent Application WO/2022/041564

Kind Code:

A1

Abstract:

A scroll compressor (100), comprising a housing (110); a partition plate (120), which is provided in the interior of the housing and which divides the interior of the housing into a suction space (210) and a discharge space (220), the partition plate being provided with a first through hole (122), so as to communicate the suction space with the discharge space; a rack (130), which is located in the suction space in the interior of the housing, the rack and the partition plate being spaced apart; a movable scroll plate (142), which is movably provided on the rack; a stationary scroll plate (144), which is provided on the rack and which cooperates with the movable scroll plate, the stationary scroll plate being provided with a second through hole (1442), and the second through hole communicating with the discharge space; and a pressure relief low-speed rotation structure (150), which is provided on the stationary scroll plate, the pressure relief low-speed rotation structure being configured to be capable of communicating the second through hole with the discharge space. When the scroll compressor is shut down, the movable scroll plate rotates at a low speed to balance the pressure difference between an intermediate pressure chamber (260) and the discharge space, preventing the movable scroll plate from rotating at a high speed and generating abrasion and abnormal sounds, and a refrigerant can be successfully discharged into the discharge space when restarting again, improving the starting up performance of the scroll compressor.
