Abstract

The invention provides a rolling rotor compressor pump body structure. The rolling rotor compressor pump body structure comprises a crankshaft, a first air cylinder, a second air cylinder, a first roller and a second roller, wherein the first roller is arranged in the first air cylinder, the second roller is arranged in the second air cylinder, and a first eccentric part matched with the first roller and a second eccentric part matched with the second roller are arranged on the crankshaft; the first air cylinder and the second air cylinder are adjacently arranged; the inner diameter of the first air cylinder is greater than that of the second air cylinder; the space between the first air cylinder and the second air cylinder is sealed by the first roller and the first eccentric part. The invention also relates to an air conditioner adopting the pump body structure. The rolling rotor compressor pump body structure has the advantages that the structure is simple, the requirements on an assembly technology are low, a compressor works stably, as a middle division plate is eliminated, the height of the pump body is reduced, the distance between an upper flange and a lower flange is shortened, the rigidity of the crankshaft is improved, and the alleviation of vibration and the lowering of noise of the crankshaft are facilitated. After the pump body structure is applied to the air conditioner, the vibration of the air conditioner is small, and the noise of the air conditioner is low.

Description

technical field [0001] The invention relates to the field of refrigeration, in particular to a pump body structure of a rolling rotor compressor without an intermediate partition and an air conditioner. Background technique [0002] According to the number of cylinders, rotary compressors can be divided into single-cylinder compressors and double-cylinder compressors. The crankshaft used in the single-cylinder compressor is a single-flap crankshaft, corresponding to a compression chamber, while the crankshaft of the double-cylinder compressor is a double-flap crankshaft. , each bell crank corresponds to a compression chamber, and the two compression chambers form an angle of 180 degrees. Each compression chamber has its own suction and exhaust passages. From the perspective of the number of parts, the pump body of the double-cylinder compressor needs two rolling rotors. , Two cylinders. The two-cylinder compressor has two suction and exhaust in one week of the rotor, so tha...
