Refrigerator compressor muffler

Abstract

The invention discloses a refrigerator compressor muffler. The refrigerator compressor muffler comprises a compressor muffler housing, an air inlet pipe, a right fixed baffle, a muffler pipe, a left fixed baffle, a muffling filter net, a muffler cover, an air outlet pipe and an air suction rubber sleeve; the main body part of the refrigerator compressor muffler is designed into the muffler pipe fixed and installed inside the compressor muffler housing through the right fixed baffle and the left fixed baffle, the air inlet pipe is connected to the inlet end of the muffler pipe, the muffling filter net is installed at the upper portion of the outlet end of the muffler pipe, the muffler cover is installed at the upper end of the muffling filter net, the air outlet pipe is installed at the center of the upper portion of the muffler cover and connected to the outlet end of the muffler pipe, and the air suction rubber sleeve is installed at the head of the air inlet pipe. The refrigerator compressor muffler is novel in design, simple in structure, good in muffling and damping effect and capable of effectively reducing or eliminating the noise and vibration inside the compressor.

Description

technical field [0001] The invention relates to the technical field of compressor mufflers, in particular to a refrigerator compressor muffler. Background technique [0002] While household refrigerator appliances bring us convenience, they also bring us troubles. The impact of refrigerator unit equipment noise on the environment and the use of rooms has been paid attention to by everyone. Among them, the built-in compressor of the refrigerator is one of the main noise sources. In order to reduce the noise, a muffler is usually added to the piping of the compressor. Ordinary expansion chamber mufflers are generally unable to eliminate noise in a certain frequency range, especially for inverter refrigerators, this phenomenon is more obvious. Moreover, once the oil in the compressor motor is sprayed out, it will flow into the pipeline. When the pipeline is long, the oil cannot return in time, resulting in insufficient lubrication of the motor. [0003] There is a particularl...

Problems solved by technology

The production process of traditional parts uses two sets of composite molds for blanking, deep drawing, punching and flanging, and completes the stamping process of parts through multiple processes, which is time-consuming and inefficient, and the scrap rate is high. Compressor mufflers are produced in large batches. Under high temperature conditions, defects such as wrinkles and scratches are not allowed on the surface, and high precision is required in use. Therefore, the surface of parts must be trimmed to ensure the plane accuracy of compressor mufflers. The stamping die processing of the refrigerator cannot detect the plane of the parts, only the whole machine is tested, and the plane accuracy of each part cannot be guaranteed, resulting in poor noise reduction effect of the refrigerator compressor
