Permanent magnet superposed hermetic scroll compressor

Abstract

The invention discloses a permanent magnetic overlapping type volution full-closed compressor which belongs to the technical field of air conditioning and refrigerating apparatuses. The invention consists of normal volution full-closed compressor parts and a drive device; the invention is characterized in that the drive device consists of a rotor plate, a still plate, a magnet isolating shell, an end cover and a location bolt. A magnetic field loop is manufactured into the round still plate of a sheet shape and the rotor plate of an armored permanent magnetic block by applying the novel design thought of overlapping the magnetic fields; the magnetic fields are enhanced by being mutually overlapped through the series connection and fixation of a drive shaft and the magnet isolating shell; simultaneously a control circuit controls at least more than two blocks of still plate loops to respectively be sucked and cut according to components; the compressor is realized to meet the running requirements of different refrigerating loads by changing the output power of the drive device and simultaneously by the proportion changes of the time for switching the percentage working situations of full load and light load, thereby further achieving the goal of saving energy. The design scheme is simpler, saves more power and is more convenient than the present digital full-closed compressor which uses an electromagnetic valve to control the flux of a cold medium.

Description

technical field [0001] The invention relates to a permanent-magnet superposition type scroll hermetic compressor, which belongs to the technical field of air-conditioning and refrigeration appliances. Background technique [0002] The scroll refrigeration compressor is a new type of volumetric compressor developed in the 1980s. It is widely used in air conditioners due to its high efficiency, small size, light weight, low noise, simple structure and stable operation. In refrigeration units, however, few people care about the innovation of the driving device for driving the scroll, which limits the further improvement and development of the energy-saving efficiency of the positive displacement compressor, and restricts the further improvement of the energy efficiency ratio of the air conditioner. .

[0002] The scroll refrigeration compressor is a new type of volumetric compressor developed in the 1980s. It is widely used in air conditioners due to its high efficiency, small size, light weight, low noise, simple structure and stable operation. In refrigeration units, however, few people care about the innovation of the driving device for driving the scroll, which limits the further improvement and development of the energy-saving efficiency of the positive displacement compressor, and restricts the further improvement of the energy efficiency ratio of the air conditioner.

In particular, it needs to be pointed out that for a long time, few people in the manufacturer have been involved in the improvement of the driving device of the compressor, and the design ideas often cannot escape the constraints of traditional concepts. It is bulky but reliable, just like some elderly people prefer to walk instead of a car for safety, which restricts the normal advantages of the permanent magnet drive device with superior technical performance in the field of compressors
