Abstract

The utility model provides a compressor which comprises a shell, a crankshaft arranged in the shell, a motor stator, a motor rotor, an upper flange, a lower flange, and a compression mechanism arranged between the upper flange and the lower flange, wherein the compression mechanism comprises a first-stage compression mechanism and a second-stage compression mechanism; the first-stage compression mechanism comprises a first cylinder; the second-stage compression mechanism is arranged at the downstream of the first-stage compression mechanism and comprises a second cylinder and a third cylinder which are arranged in parallel; the output volume of the first cylinder is greater than or equal to the sum of the output volumes of the second cylinder and the third cylinder. According to the compressor disclosed by the utility model, under the same cylinder diameter, the second cylinder and the third cylinder can be combined to form the second-stage compression mechanism, so that the output volume of the double-stage compressor is increased, and the output volume range of the double-stage compressor is expanded under the conventional cylinder diameter; the performance and the heating capacity of the compressor are improved.

Description

technical field [0001] The present invention relates to the field of compressors, in particular, to a compressor. Background technique [0002] Existing rolling rotor type two-stage compressors are generally two-cylinder two-stage compressors. First, the displacement of the two-stage compressors is smaller than that of the two-cylinder single-stage compressors. Second, the balance of rotation is not as good as that of the two-cylinder single-stage compressors. However, there is a big gap between the energy efficiency and heating capacity of the single-stage compressor compared with the two-stage compressor, and the displacement of the two-cylinder two-stage compressor is enlarged. [0003] At present, the displacement of the two-stage compressor is generally expanded by enlarging the diameter of the compressor, which will lead to an increase in the cost of the compressor itself and the manufacturing cost of the air conditioner. In order to expand the displacement of the com...
