Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electric compressors, and particularly relates to an ultrahigh-efficiency heat pump type electric scroll compressor. BACKGROUND

[0002] A scroll compressor for an air conditioner, a refrigerator, and the like has a structure provided with a compression mechanism portion that compresses refrigerant in a compression chamber formed by combining a fixed scroll and an oscillating scroll, and a container that houses the compression mechanism portion. The fixed scroll and the oscillating scroll each have a structure in which a spiral body is erected on a base plate, and the spiral bodies are engaged with each other to form the compression chamber. By causing the oscillating scroll to perform an oscillating motion, the compression chamber is reduced in volume and moved, and the suction and compression of refrigerant are performed in the compression chamber.

[0003] A heat pump type scroll compressor for an electric vehicle air conditioner is disclosed in Chinese Patent No. CN102865228B. Two air supplement holes are arranged in the suction cavity of the scroll bottom surface of the static scroll disc, close to the spiral rib position. An omega-shaped isolation belt is arranged in the high-pressure cavity area of the reverse side of the static scroll disc, which separates the high-pressure cavity area from the intermediate air supplement cavity area and the two air supplement holes.

[0004] Although the above-mentioned compressor can isolate the high-pressure cavity and the intermediate air supplement cavity through the isolation belt, the temperatures of the two cavities are different, and heat is transferred through the isolation belt, which easily causes mutual influence between the high-pressure cavity and the intermediate air supplement cavity, resulting in low efficiency of the compressor. SUMMARY

[0015] The high-pressure chamber is a chamber for discharging compressed gas by the dynamic scroll and the static scroll, and the high-pressure chamber is provided with an intermediate air supplement chamber for supplementing air, thereby improving the discharge capacity of the compressor, reducing the discharge temperature, and improving the heating capacity.

The cover plate is used to open the vacuum chamber, and the reinforcing member is installed in the vacuum chamber. The reinforcing member is fixed to the cover plate by the locking mechanism. When the vacuum chamber is in a vacuum state, the cover plate and the isolation belt are attracted under the action of air pressure, thereby improving the structural stability between the isolation belt, the cover plate, and the reinforcing member. When the cover plate is installed, the air in the vacuum chamber is connected to an air extraction pump through the valve plate mechanism to extract the vacuum chamber, thereby achieving high heat insulation function, improving the temperature isolation performance between the high-pressure chamber and the intermediate air supplement chamber, ensuring the working efficiency of the compressor, preventing heat conduction between the corresponding isolation belts of the static scroll and the casing, and further preventing gas circulation through the sealing performance.
