Title:
VARIABLE CAPACITY COMPRESSOR, CYLINDER SWITCHING METHOD AND AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2020/062608
Kind Code:
A1
Abstract:
A variable capacity compressor, a cylinder switching method and an air conditioner. The variable capacity compressor comprises: a cylinder (1); a rotor (2), provided in the cylinder (1), and forming an air chamber between the rotor and the inner wall of the cylinder (1), the rotor (2) being movable along the inner wall of the cylinder (1); and a sliding piece (3) having a first operating position and a second operating position. In the first operating position, the sliding piece (3) is not in contact with the rotor (2), and the cylinder (1) is in a non-operating state; and in the second operating position, the sliding piece (3) is in contact with the rotor (2), so as to divide the air chamber into a suction chamber and a discharge chamber, and the cylinder (1) is in an operating state. The sliding piece (3) is configured to shift from the first operating position to the second operating position when the positional relationship between the sliding piece (3) and the rotor (2) satisfies a preset condition. The variable capacity compressor can reduce the movement stroke of the sliding piece to the rotor (2) when the sliding piece (3) shifts from the first operating position to the second operating position, and reduce the impact force and noise generated by the collision between the two, facilitating full contact in one step, and reducing the impact deformation of the sliding piece (3) and the rotor (2).
