Scroll compressor with air preheating effect

Abstract

The invention discloses a scroll compressor with an air preheating effect. The scroll compressor structurally includes an exhaust hole, an exhaust cavity, a static scroll, a movable scroll, a heatingand heat preservation mechanism, a motor, a main shaft, an oil tank and a shell, the top end of the interior of the shell is provided with the exhaust cavity, the exhaust hole is formed in the position, located on the exhaust cavity, of the shell, the static scroll is arranged under the exhaust cavity, and the static scroll and the movable scroll are matched in a crossed manner. By means of the scroll compressor, an outer ring body, a rotating ceramic tube and an inner ring body are matched, the rotating ceramic tube is influenced by airflow to directly roll when outside cold air is sucked in,single-face whitening cannot be caused due to even heating and cooling in the rolling process, and consequently embrittlement and rupture are caused. A connecting block and a gasket are arranged between the rotating ceramic tube and the outer ring body, so that on one hand, influences of vibration on the rotating ceramic tube are weakened, and on the other hand, the connecting block and the gasket serve as thermal insulation components to isolate part of the heat, and influences of the heat on the outer ring body and the inner ring body are reduced.

Description

technical field [0001] The invention relates to the field of air conditioner compressors, in particular to a scroll compressor with air preheating effect. Background technique [0002] When the air conditioner is heating, the gas refrigeration compressor is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (in this case, the condenser), condenses and liquefies and releases heat to become a liquid, and at the same time heats the indoor air, thereby achieving The purpose of increasing the indoor temperature is that the refrigerant evaporates into a gas in the outdoor unit and absorbs the heat in the air, so the evaporation temperature of the refrigerant must be lower than the outdoor temperature. The existing public application number is CN201910418334.3, a scroll compressor The heating device of the machine uses a PTC heating device to preheat the inhaled air, but because it is outdoors, in a c...

[0002] When the air conditioner is heating, the gas refrigeration compressor is pressurized by the compressor to become a high-temperature and high-pressure gas, which enters the heat exchanger of the indoor unit (in this case, the condenser), condenses and liquefies and releases heat to become a liquid, and at the same time heats the indoor air, thereby achieving The purpose of increasing the indoor temperature is that the refrigerant evaporates into a gas in the outdoor unit and absorbs the heat in the air, so the evaporation temperature of the refrigerant must be lower than the outdoor temperature. The existing public application number is CN201910418334.3, a scroll compressor The heating device of the machine uses a PTC heating device to preheat the inhaled air, but because it is outdoors, in a cold environment, the temperature is easy to drop. Use, it is easy to cause whitening and embrittlement on one side, break during vibration, and fragments get stuck in other parts, resulting in poor operation
