Problems solved by technology

[0004] However, the suction muffler of the direct suction type in the prior art as described above has the following problem: when the compressor is running, the internal pressure of the compressor closed container will be greater than the internal pressure of the suction muffler, so the excess oil It will flow into the silencer space of the suction silencer through the through-hole of the suction silencer from the inner space of the compressor closed container, thereby reducing the suction amount of the refrigerant, which will lead to a decrease in the performance of the compressor

Embodiment Construction

[0018] Hereinafter, embodiments of the compressor suction muffler of the present invention will be described in detail with reference to the accompanying drawings.

[0019] like figure 1 As shown, the reciprocating compressor equipped with the suction muffler of the present invention is composed of the following parts: a compressor closed container 1 ; a drive motor 2 arranged inside the compressor closed container 1 ; and a compressor body 3 . The compressor body 3 can compress the refrigerant under the action of the driving motor 2 . The compressor body 3 is composed of the following parts: a cylinder block 11 , a connecting rod 12 , a piston 13 , a valve assembly 14 , a discharge cover 15 , and a suction muffler 100 .

[0020] like figure 2 as well as Figure 4 As shown, the suction muffler 100 is composed of the following parts: a first casing 110 and a second casing 120 that form a sound-absorbing space V inside; the suction muffler 100 is arranged in the sound-absorb...

Abstract

The invention relates to a silencer of compressor, a suction pipe is directly connected with a suction silencer, a first through hole and a second through hole are respectively formed at a side surface and a bottom surface of the suction silencer. Therefore, when the suction pipe is close to a suction guide pipe of the suction silencer or is directly connected with the suction guide pipe of the suction silencer, the balance between the internal pressure of a compressor enclosed container and the internal pressure of the suction silencer can be maintained, accordingly, the oil in the compressorenclosed container can not excessively flow into the suction silencer, and the supply of appropriate oil amount can be guaranteed, thereby improving the performance and the reliability of the compressor.

Description

technical field [0001] The present invention relates to compressors, and more particularly, to a muffler that can reduce compressor noise. technical background [0002] Generally, a suction muffler is provided on the suction side of the compressor compression mechanism. The function of the suction muffler is to reduce the valve noise, flow noise, or pressure pulsation noise generated when the refrigerant is sucked into the compression mechanism. The suction muffler is composed of the following parts: a muffler space for reducing the noise generated when the refrigerant is sucked in; an outflow port provided on the other side of the muffler space and connected to the suction side of the compression mechanism. According to needs, the silencing space can be divided into a plurality of silencing spaces, and the plurality of silencing spaces can be arranged in a parallel or in-line manner. [0003] According to the form of use on the compressor, suction mufflers can be divided ...
