Description

Technical Field

[0001] This utility model belongs to the technical field of refrigeration compressor accessories, specifically relating to a housing structure for a refrigeration compressor intake muffler. Background Technology

[0002] The function of refrigeration compressor suction silencers is well-known in the industry and can be found extensively in published Chinese and foreign patent documents. For example, CN105201781A discloses a "modular refrigeration compressor suction silencer." The silencer housing of this patent is one-piece, and when the communicating vessel is inserted into the silencing cavity of the silencer housing, the silencing cavity is divided into two silencing chambers (referred to in the patent as "first silencing chamber and second silencing chamber") by communicating vessel side wing plates integrally formed on both sides of the communicating vessel. Compared with CN202645935U (a fully enclosed refrigeration compressor suction silencer), this patent solution has a certain advantage in silencing effect. This is because one of the two silencing chambers mentioned in CN202645935U (referred to in the patent as the "upper chamber") is formed on the cover, so the housing is essentially still only one chamber. Not limited to the aforementioned muffler shell structure, since it is a single piece, the number of muffler chambers in the shell cavity and the structure and number of muffler chamber partitions used to separate the muffler chambers are limited. As the number of muffler chambers increases, the number of muffler chamber partitions used to separate the muffler chambers also increases accordingly, which causes confusion in the demolding process of the molded shell, or even makes demolding impossible. Utility Model Content

[0003] The objective of this invention is to provide a refrigeration compressor intake silencer housing structure that helps to transform an integral housing into a pair of symmetrical split structures with the same shape and construction, thereby reasonably increasing the silencing chamber and improving the silencing effect during use, as well as facilitating demolding during manufacturing.

[0004] The present invention achieves its objective by providing a refrigeration compressor intake muffler housing structure, comprising a housing and a muffler partition mechanism. The housing comprises a front half-shell and a rear half-shell, the front and rear half-shells having identical shapes and fitting face-to-face. On the side of the front half-shell facing the rear half-shell, at a position midway along its height, are formed a pair of horizontally spaced and parallel transverse convex strips extending from the left to the right side of the front half-shell. The space between these transverse convex strips forms a front half-shell slot for the muffler partition. Furthermore, a pair of longitudinal convex strips are formed above the midway along the length of the pair of transverse convex strips, the space between these longitudinal convex strips forming a longitudinal space for the muffler partition. The front half-shell slot of the partition plate has a pair of parallel and laterally spaced rear half-shell transverse protrusions on the side of the rear half-shell facing the front half-shell, corresponding to the pair of front half-shell transverse protrusions. The space between the pair of rear half-shell transverse protrusions forms the rear half-shell slot of the anechoic chamber partition plate. A pair of rear half-shell longitudinal protrusions are formed on the side corresponding to the pair of front half-shell longitudinal protrusions. The space between the pair of rear half-shell longitudinal protrusions forms the rear half-shell slot of the anechoic chamber partition plate. The anechoic chamber partition plate mechanism, through its insertion with the front and rear half-shell slots of the anechoic chamber partition plate, the front half-shell slot of the anechoic chamber partition plate, and the rear half-shell slot of the anechoic chamber partition plate, separates the upper left anechoic chamber, the right anechoic chamber, and the lower anechoic chamber between the opposing sides of the front and rear half-shells.

[0005] In a specific embodiment of this utility model, the anechoic chamber partition mechanism includes a front longitudinal partition, a rear longitudinal partition, a front transverse partition, and a rear transverse partition. The front edge of the front longitudinal partition is inserted into a slot in the front half of the anechoic chamber partition. A front longitudinal partition protrusion is formed on the rear side of the front longitudinal partition. The rear edge of the rear longitudinal partition is inserted into a slot in the rear half of the anechoic chamber partition. A rear longitudinal partition protrusion mating groove is formed on the front side of the rear longitudinal partition. The anechoic chamber partition mechanism is formed by the mating of the front longitudinal partition protrusion and the rear longitudinal partition protrusion mating groove. The front and rear longitudinal partitions are spliced ​​together as a whole, and the bottom surfaces of the front and rear longitudinal partitions are sealed to the upward-facing surfaces of the front and rear transverse partitions, respectively. The front edge of the front transverse partition is inserted into the slot of the front half shell of the anechoic chamber transverse partition, and a front transverse partition insertion groove is formed on the rear edge of the front transverse partition. The rear edge of the rear transverse partition is inserted into the slot of the rear half shell of the anechoic chamber transverse partition, and a rear transverse partition insertion protrusion is formed on the front edge of the rear transverse partition. The rear transverse partition insertion protrusion is inserted into the slot of the front transverse partition.

[0006] In another specific embodiment of this utility model, the space located to the left of the front longitudinal partition is configured as the left anechoic chamber of the front half of the front shell, the space located to the right of the front longitudinal partition is configured as the right anechoic chamber of the front half of the front shell, and the space located below the front transverse partition is configured as the lower anechoic chamber of the front half of the front shell; the space located to the left of the rear longitudinal partition is configured as the left anechoic chamber of the rear half of the rear shell, the space located to the right of the rear longitudinal partition is configured as the right anechoic chamber of the rear half of the rear shell, and the space located below the rear transverse partition is configured as the lower anechoic chamber of the rear half of the rear shell.

[0007] In another specific embodiment of this utility model, the left silencing chamber of the shell is formed by the cooperation of the left silencing chamber of the front half shell and the left silencing chamber of the rear half shell, the right silencing chamber of the shell is formed by the cooperation of the right silencing chamber of the front half shell and the right silencing chamber of the rear half shell, and the lower silencing chamber of the shell is formed by the cooperation of the lower silencing chamber of the front half shell and the lower silencing chamber of the rear half shell.

[0008] The technical solution provided by this utility model transforms the integral shell in the existing technology into a pair of separate structures with the same shape and structure that cooperate in a face-to-face state. Therefore, it can increase the number of anechoic chambers to three to improve the anechoic function in use, and also meet the requirements for convenient demolding during the molding process.
