Problems solved by technology
[0015] Yet, adopt the assembling method of the discharge pipe of the scroll compressor in the conventional technology, in the process of connecting the discharge pipe mortise firmly to the recessed hole of the muffler, under the effect of extrusion force, in the Deformation can occur in the upper cover and compression unit, and if there is insufficient compression between the muffler and the discharge pipe, fluid leakage can occur, reducing compressor performance and efficiency
[0016] In addition, since an additional mortising device is required for mortising the exhaust pipe, this will increase the manufacturing cost

An assembling mechanism of a discharge pipe and a method thereof, capable of preventing deformation of an upper cover and a compression unit generated in assembling the discharge pipe by improving assembling mechanism of the discharge pipe, thus to improve performance of the compressor. The assembling mechanism includes an upper cover on which a guide member having a discharge pipe inserted therein is mounted, a muffler in which an insertion hole having the discharge pipe inserted therein is formed, a first connection portion for welding / combining the discharge pipe and the muffler after inserting the discharge pipe in the insertion hole and a second connection portion for welding / combining the upper cover and discharge pipe.
Description
technical field [0001] The present invention relates to an assembly mechanism and an assembly method of an exhaust pipe, in particular to an assembly mechanism and an assembly method for an exhaust pipe of a hermetic compressor, that is, such an assembly mechanism and an assembly method can prevent components from Deformation occurs during the installation operation of the discharge pipe, so that the efficiency of the compressor can be improved. Background technique [0002] In general, compressors can be manufactured in various forms according to compression methods, and for air conditioners that require smaller volume and lighter weight, hermetic rotary compressors are mainly used. [0003] The hermetic compressor may be classified into a rotary compressor, a reciprocating compressor, a scroll compressor, and the like according to a fluid compression method. [0004] figure 1 is a cross-sectional view of a scroll compressor according to conventional technology; [0005]...
