Air cylinder of compressor, compressor, air conditioner with compressor and heat pump water heater with compressor

Abstract

The invention provides an air cylinder of a compressor, the compressor, an air conditioner with the compressor and a heat pump water heater with the compressor in order to increase the discharge capacity of the compressor under the condition that the outer circumferential size of the air cylinder is unchanged. A slip sheet groove, an air suction port and an exhaust port are formed in the air cylinder of the compressor, provided by the invention, the air suction port and the exhaust port are arranged at two sides of the slip sheet groove, the air cylinder comprises an inner circumference and an outer circumference, and the circle center of the inner circumference is deviated from the circle center of the outer circumference. Due to the eccentric arrangement of the circle centers of the inner circumference and the outer circumference, the limit of the internal to external diameter ratio of the air cylinder to the discharge capacity design is overcome, and the design range of the discharge capacity is widened.

Description

Technical field [0001] The present invention relates to the field of compressors, and more specifically, to a cylinder of a compressor. Background technique [0002] Currently, cylinders used in rolling rotor compressors are mainly divided into circular, axe and Q-shaped cylinders. Such as figure 1 As shown, the inner circle 11 and the outer circle 12 of the cylinder of the above structure are concentric structures. Under the premise that the cylinder inner and outer circles are concentric, the cylinder inner and outer diameter ratio has a maximum limit, and the expansion of the compressor is limited by the cylinder inner and outer diameter ratio, which is not conducive to the expansion of the compressor discharge capacity. Summary of the invention [0003] The purpose of the present invention is to provide a new type of compressor cylinder, in order to improve the displacement of the compressor without changing the outer circumference of the cylinder. [0004] In order to achieve...

AI Technical Summary

Problems solved by technology

Under the premise that the inner and outer circles of the cylinder are concentric, the ratio of the inner and outer diameters of the cylinder has a maximum value, and the displacement expansion of the compressor is limited by the ratio of the inner and outer diameters of the cylinder, which is not conducive to the expansion of the compressor's exhaust capacity.
