Description
Technical Field
The utility model relates to a compressor technical field specifically is a multistage expansion silencer and compressor of breathing in.
Background
The compressor is the heart of household electrical appliances such as refrigerator, freezer, air conditioner, and its during operation constantly inhales the refrigerant, discharges through compressing after doing work, inhales and exhaust the in-process air current can produce the noise, at present along with the improvement of people's quality of life, and the noise requirement to household electrical appliances is more and more strict, consequently need to install the silencer of breathing in to the compressor inside, and the current silencer of breathing in is not good to the noise elimination effect of high frequency channel, has influenced the noise elimination effect of complete machine.
Disclosure of Invention
The utility model aims at providing a silencer and compressor are breathed in order to solve present silencer of breathing in not good to the noise elimination effect of high frequency channel, have influenced the noise elimination effect's of complete machine problem, provide a multistage expansion.
The utility model has the following concrete scheme: the utility model provides a silencer is breathed in to multistage expansion, includes the shell, and the inside noise elimination chamber that is equipped with of shell is equipped with air inlet and gas outlet on the shell, air inlet and gas outlet all communicate with noise elimination chamber, be equipped with at least two-stage expanding structure from air inlet to gas outlet in the noise elimination chamber, expanding structure includes tubaeform baffle, the osculum orientation of tubaeform baffle the air inlet, the macrostoma orientation the gas outlet, the macrostoma and the shell inner wall connection of tubaeform baffle.
The utility model discloses distance between every adjacent two-stage expanding structure's tubaeform baffle equals.
The osculum sectional area of tubaeform baffle is 1/100~1/20 of macrostoma sectional area.
The utility model also provides a compressor, it installs above-mentioned silencer of breathing in.
The working principle of the utility model is as follows: refrigerant firstly enters a muffler after being sucked into a compressor, enters a muffler cavity from an air inlet of the muffler, then passes through an expansion structure step by step, and finally enters a compressor cylinder from an air outlet.
Compared with the prior art, the utility model has the following advantages: effectively reduce the noise of high-frequency channel, promoted the noise cancelling effect of silencer, reduced compressor noise of operation.
