摘要： A compressor includes: a compression space with an annular shape comprising an inner circumferential surface and an outer circumferential surface; and a discharge opening formed in a direction parallel to a shaft direction of the compressor, to discharge a refrigerant compressed in the compression space, wherein a first portion of a cross-sectional area of the discharge opening overlaps a portion of a cross-sectional area of the compression space, a second portion of the cross-sectional area of the discharge opening does not overlap the cross-sectional area of the discharge opening, and the ratio of the non-overlapping second portion of the cross-sectional area of the discharge opening to the entire cross-sectional area of the discharge opening is 0.1 or less. With such a configuration, a dead volume generated in the compression space can be reduced, and thus compressor efficiency can be enhanced.

摘要： A heat pump clothes dryer comprising a circulating air path consisting of a drying drum and a drying air path for circularly flowing drying air; and a heat pump system consisting of an evaporator, a throttling device, a condenser and a compressor successively connected end to end for circularly flowing a refrigerant medium. The condenser and the evaporator are disposed on the drying air path, and perform heat exchange with the drying air. The compressor has independent suction compression chambers, each suction compression chamber being switchably connected in series or in parallel. When the dryer starts drying in a low-temperature environment, the suction compression chambers of the compressor operate in a parallel state, so that the air displacement of the compressor is increased to improve the flowing activity of the refrigerant medium in the heat pump system, so as to avoid occurrence of frosting of the evaporator.
