A suction muffler applied to a compressor

Abstract

The invention discloses a suction muffler applied to a compressor, comprising an upper cover (1), a middle partition (4) and a casing (5); the top of the upper cover (1) is provided with an air outlet pipe ( 12) and outlet pipe 2 (13), the bottom of the upper cover (1) is provided with installation groove 1 (14), and the inner middle is provided with installation groove 2 (15); the inside of the middle partition (4) is provided with a separation plate One (42), the bottom is provided with the installation groove three (410); the top of the housing (5) is provided with the installation notch (57), and the inside is provided with the separation plate two (56); the middle partition (4 ) is set in the housing (5), and the installation groove three (410) is matched with the separation plate two (56); the upper cover (1) is set on the middle partition (4) and the top of the housing (5), Groove one (14) cooperates with installation notch (57), and installation groove two (15) cooperates with separation plate one (42). The invention can improve gas transmission efficiency and reduce oil discharge, so it has broad market prospects.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a suction muffler applied to compressors. Background technique [0002] In the suction and exhaust structure of the current refrigerator compressor, the suction muffler has only one air outlet, and the air outlet of the muffler is pressed against the air inlet of the valve plate by buckles, and there is only a single air flow channel inside the muffler. There are two defects in this structure. One is that during the transportation of the compressor and the moment the compressor starts and stops, the movement and the shell will collide, and the buckle fixing the air outlet of the muffler is easy to loosen, causing the air outlet of the muffler to be sealed with the valve plate. If it is not strict, it will lead to the failure of the suction muffler, which will not achieve the effect of eliminating noise and reducing the suction pulsation. At the same time, it will also reduce ...

Problems solved by technology

There are two defects in this structure. One is that during the transportation of the compressor and the moment the compressor starts and stops, the movement and the casing will collide, and the buckle fixing the air outlet of the muffler is easy to loosen, resulting in the air outlet of the muffler being sealed with the valve plate. If it is not strict, it will lead to the failure of the suction muffler, which will not achieve the effect of eliminating noise and reducing the suction pulsation. At the same time, it will also reduce the suction efficiency of the compressor and reduce the cooling capacity of the compressor. In addition, the lubricant mixed in the gaseous refrigerant The oil mist will be directly sucked into the cylinder without passing through the muffler, and finally discharged from the compressor through the exhaust channel and enter the refrigeration system, which will reduce the heat exchange efficiency of the refrigeration system and increase the power consumption of the refrigeration system

The second is that there is only a single airflow channel inside the muffler, and the gaseous refrigerant coming out of the muffler is directly sucked into the cylinder. Due to the periodic characteristics of suction and exhaust when the refrigerator compressor is working, suction pulsation occurs, which reduces the suction of the compressor. gas efficiency
