Embodiment Construction

[0020] Referring to Fig. 1, the present invention has housing 8, and compressor movement assembly 15 is housed in housing 8, includes a muffler chamber 14, and the outer wall of housing 8 is connected with suction pipe 9, and the pipe of suction pipe 9 The mouth opens into the housing 8 and faces the suction port 13 of the muffler cavity 14 . Especially in the utility model, a connecting pipe 5 is used to connect the mouth of the suction pipe 9 and the suction port 13 of the muffler cavity. The right end of the connecting pipe 5 is a flanging mouth, on which a Sealed collection port 7, the sealed collection port 7 covers the mouth of the suction pipe 9, and is closely attached to the inner wall of the housing 8; the left end of the connecting pipe 5 is inserted into the suction port 13 of the muffler chamber (move-fit connection), The docking of connecting pipe 5 and the suction port 13 of muffler cavity can also design a shorter suction pipe on suction port 13, and connecting...

Abstract

The invention provides a compressor in a mode that springs impact an air suction mouth to directly suck air, and the compressor comprises a casing body. A cassette mechanism assembly is arranged in the casing body; the outer wall of the casing body is connected with an air suction pipe; an anechoic cavity is arranged in the casing body corresponding to a pipe mouth of the air suction pipe. The invention is characterized in that a connecting pipe is connected with the pipe mouth of the air suction pipe and the air suction mouth of the anechoic cavity; one end of the connecting pipe is providedwith a turned-over edge to mantle the pipe mouth of the air suction pipe, and the other end of the connecting pipe forms an even joint with the air suction mouth of the anechoic cavity; the outer wall of the connecting pipe is provided with the springs; the springs impact a turned-over edge mouth of the connecting pipe to be tightly pasted to the inner wall of the casing body. The invention overcomes the problems of easy distortion and aging, short service life and high cost in high temperature as the prior art adopts the structure that a ripple pipe directly sucks the air. The invention can also reduce noise, and is especially suitable for the improvement of a piston type compressor.

Description

(1) Technical field: [0001] The invention relates to the technical field of refrigerating compressors, and relates to a compressor in which a spring compresses an air inlet and directly inhales air. (two) background technology: [0002] In the prior art, the muffler cavity in most compressors adopts a semi-direct suction method (that is, the suction port of the muffler cavity is not directly connected to the suction pipe on the shell, but has a certain distance), so this A semi-direct suction compressor has low efficiency, high suction temperature, and a large loss in volumetric efficiency of the compressor. The more advanced suction method of the muffler chamber is to use a bellows to connect the suction port of the muffler chamber with the suction pipe on the shell to inhale directly, so that the gas with a lower temperature can be directly sucked in. Although this structure can improve the COP value, the bellows, lubricating oil and working fluid are easily deformed and ...
