Sound absorbing cover, compressor, air conditioner

Abstract

The invention provides a sound-absorbing cover, a compressor, and an air conditioner, wherein the sound-absorbing cover includes a cover body, the cover body has a bottom wall and a vertical wall arranged around the outer peripheral edge of the bottom wall, and a first scroll partition is arranged on the bottom wall , the second scroll partition, the first end of the first scroll partition and the first end of the second scroll partition are respectively connected to the vertical wall, and the second end of the first scroll partition surrounds the exhaust port of the pump body Set, and the first outlet is formed between the second end of the first vortex separator and the first vortex separator, the second end of the second vortex separator is on the airflow outflow path of the first outlet, and the first outlet The airflow can flow out of the muffler cover through the first flow channel and the second flow channel respectively. The first flow channel is jointly formed by the first vortex partition and the second vortex partition, and the second flow channel is formed by the second vortex partition and the vertical wall. co-formed. According to the sound-absorbing cover, the compressor and the air conditioner of the present invention, the resistive sound-absorbing and noise-reducing effect of the exhaust airflow can be improved more effectively, and the use comfort of users can be improved.

Description

technical field [0001] The invention belongs to the technical field of compressor manufacturing, and in particular relates to a sound-absorbing cover, a compressor and an air conditioner. Background technique [0002] Scroll compressors have many advantages such as small size, light weight, continuous and stable suction and exhaust, low vibration, low noise, low energy consumption, etc., and are widely used in air conditioning and refrigeration, power engineering, transportation and other fields. The scroll compressor is mainly composed of two double-function equation scrolls, the movable and static scrolls meshing with each other. During the compression operation, the fixed scroll is fixed on the frame, and the movable scroll is driven by the crankshaft and the anti-rotation mechanism Constraints, rotate around the center of the base circle of the fixed scroll with a small radius, the gas or refrigerant is sucked from the periphery of the fixed scroll, and rotates with the ...

Problems solved by technology

However, this structure of the sound-absorbing cover can only reduce the low-frequency noise of the compressor, but has no significant effect on reducing the high-frequency noise. Therefore, this sound-absorbing structure is no longer suitable for noise reduction of high-frequency and high-speed compressors in the future.
