AI Technical Summary

Benefits of technology

The present invention provides a suction muffler for a hermetic compressor that includes two bodies that are coupled together to create a space for removing noise from a working fluid. The two bodies have openings with matching rims that have a coupling rib and a coupling channel, which are used to connect the two bodies together. The technical effect of this invention is to improve the performance and efficiency of the compressor by reducing noise and vibration.

Problems solved by technology

The technical problem addressed in this patent is how to improve the accuracy and reliability of the ultrasonic welding process used to join different parts of a suction muffler in a hermetic compressor.

Embodiment Construction

[0036]Hereinafter, a suction muffler for a hermetic compressor according to an exemplary embodiment of the present invention will be described with reference to the accompanying drawings.

[0037]FIG. 3 is an exploded perspective view showing the construction of a suction muffler for a hermetic compressor according to an exemplary embodiment of the present invention; FIG. 4 is an exploded sectional view showing the major construction of the suction muffler; and FIG. 5 is a sectional view showing the major construction of the suction muffler.

[0038]As shown in the drawings, the suction muffler includes first and second bodies 31 and 32, which are made of synthetic resin, and each of which has a space defined therein. The first and second bodies 31 and 32 are coupled to each other by coupling protrusion and recess 40 and 50 (described later) so that a space for removing noise is created inside the suction muffler.

[0039]It is to be noted that the suction muffler does not necessary consist ...

Abstract

Disclosed is a suction muffler for a hermetic compressor. The suction muffler includes first and second bodies coupled to each other. The first and second bodies have coupling protrusion and recess formed in corresponding positions, respectively. A coupling rib protrudes from the coupling protrusion, and a coupling channel is formed as an indentation on the coupling recess. Coupling guide surfaces are formed on corresponding portions of the coupling rib and recess, respectively, so that the coupling protrusion and recess can be fastened to each other more smoothly. The coupling guide surfaces of the coupling protrusion and recess guide and facilitate the coupling between the first and second bodies. The coupling protrusion and recess are coupled to each other by geometric characteristics so that no separate process is necessary to couple the first and second bodies to each other. This improves the productivity and quality of the suction muffler.
