Compressor with bottom cover and bearing block arrangement

A compressor, comprising:

• a housing, which comprises a cylindrical body, and a first cover and a second cover respectively arranged at two axial ends of the cylindrical body;
• a compression mechanism accommodated in the housing and configured to compress a working fluid;
• a crankshaft configured to drive the compression mechanism;
• a motor configured to drive the crankshaft to rotate, and
• a bearing block accommodated in a space defined by the motor and the housing and fixedly attached to the housing, wherein the bearing block is configured to rotatably support the crankshaft through a bearing,
• wherein the housing has a cylindrical reinforcing part for defining the space, a rigidity of the cylindrical reinforcing part is greater than a rigidity of other parts of the housing,
• wherein the first cover comprises a base part and an axial extension part, the axial extension part extends from an outer periphery of the base part in an axial direction of the compressor,
• wherein an axial height measured from a bottom surface of the bearing block to the outer periphery of the base part of the first cover is H, and an axial extension height of the cylindrical reinforcing part is greater than or equal to half of H, and
• wherein a gap is formed between an end face of the axial extension part and the bearing block, the gap is greater than or equal to 0.5 mm and less than or equal to 3 mm.
