Abstract
The utility model relates to a totally enclosed refrigeration compressor suction silencer which comprises an upper cavity (2) and a lower cavity (3). The upper cavity (2) is connected with the lower cavity (3) in sealed mode through a welding steel wire (4), the upper cavity (2) is provided with an air outlet pipe (5), and the lower cavity (3) is provided with an air inlet pipe (6). According to the suction silencer, an air admission hole (1) of the lower cavity (3) is omitted, and the air inlet pipe (6) is connected with a rubber sleeve (7) of a trumpet-shaped structure. By means of the design of the totally enclosed refrigeration compressor suction silencer, work efficiency of a compressor is improved by more than 2.0%, refrigeration oil circulation volume of the compressor is reduced by more than 10% in a refrigerator system, and therefore the totally enclosed refrigeration compressor suction silencer has wide market prospect.
Description
Technical field
The utility model relates to refrigeration compressor Component field, especially a kind of hermetically sealed compressor air suction silencer.
Background technique
For hermetically sealed compressor, the lower air input efficiency that then is conducive to improve compressor of the refrigerant temperature of suction.Therefore, the air suction silencer employing adiabaticity of hermetically sealed compressor preferably plastics is made, its objective is that reduce sucks the temperature of refrigeration agent, simultaneously in order further to improve the air input efficiency of compressor, the direct inhaling silencer of general employing, but the existing directly air-breathing institute's device that disappears designs as shown in Figure 1, usually with one or more tonifying Qi hole 1, be used for solving the problem of gettering quantity deficiency, but because the refrigerant temperature in the silencing apparatus is low, and the refrigerant temperature outside the silencing apparatus is higher, so after external refrigerant enters silencing apparatus by tonifying Qi hole 1, cause the refrigerant temperature in the silencing apparatus to raise, causing the compression mechanism cold efficiency is that COP descends; In addition because the outer refrigeration agent of silencing apparatus is actually the mixture of refrigeration agent and mist of oil, so can bring compressor and freeze oil in compressor assembly by the refrigeration agent that the tonifying Qi hole sucks, increase the circulating load of refrigeration oil in the compressor, caused the power consumption of refrigerator to rise.
The mouth of pipe of conventional muffler sucking pipe is concordant design with the inwall of compressor housing substantially, spattering like this refrigeration oil on inner walls and the refrigeration oil in the compressor inner refrigerant mist of oil in the compressor can be along the inwall of housing in the action of gravitation current downflow, when refrigeration oil flows to the air-breathing mouth of pipe, the refrigeration agent that is easily sucked by sucking pipe is brought in the compressor assembly, increased the circulating load of refrigeration oil in the compressor, so that the power consumption of refrigerator rises.
Summary of the invention
In order to address the above problem, the utility model provides a kind of hermetically sealed compressor air suction silencer.
For solving the problems of the technologies described above the technical solution of the utility model be: a kind of hermetically sealed compressor air suction silencer, comprise epicoele, cavity of resorption, the two links to each other by the welding wire sealing, described epicoele is provided with steam outlet pipe, described cavity of resorption is provided with suction tude, it is characterized in that: cancelled the tonifying Qi hole of cavity of resorption, be connected with the rubber sleeve that is horn-like structure in suction tude.
The small end of described rubber sleeve is connected with described suction tude, and the large end shield of described rubber sleeve is in the inlet of the housing sucking pipe of compressor.
The large end Thickness Ratio of described rubber sleeve small end is thin.
The mouth of pipe of described sucking pipe protrudes from the inwall of housing.
Described sucking pipe place housing inwardly is provided with boss.
Be provided with central diaphragm and straight tube in the above-mentioned epicoele.
Described straight tube bottom is provided with filter screen.
Can obtain following useful technique effect by implementing the utility model: the efficiengy-increasing of (1) compressor is more than 2.0%; (2) compressor reduces more than 10% in refrigeration oil circulating load on the refrigerator system, so that the compressor available machine time shorten during the refrigerator coupling, power consumption reduces.

Among the figure: 1, tonifying Qi hole, 2, epicoele, 3, cavity of resorption, 4, welding wire, 5, steam outlet pipe, 6, suction tude, 7, rubber sleeve, 8, the rubber sleeve small end, 9, the large end of rubber sleeve, 10, housing, 11, sucking pipe, 12, central diaphragm, 13, straight tube, 14, filter screen, 15, silencing apparatus, 16, the sucking pipe mouth of pipe.
Specific embodiment
Below in conjunction with accompanying drawing 2,3,4 and embodiment the utility model is described in further detail:
As shown in Figure 4, the utility model silencing apparatus is by epicoele 2, cavity of resorption 3, and welding wire 4, rubber sleeve 7 forms; Epicoele 2 and cavity of resorption 3 are by welding wire 4 welded seals, and heat exchange and oil extraction in silencing apparatus 15 inner refrigerants and the housing 10 are reduced in cancellation tonifying Qi hole 1 in the cavity of resorption 3; Cavity of resorption 4 designs enough greatly, and the refrigeration agent of storage satisfies the demand of compressor valve port inspiratory flow fully, and epicoele 2 is comprised of steam outlet pipe 5, two central diaphragms 12, straight tube 13, spherical filter screens 14.
As shown in Figure 2, the edge of the rubber sleeve 7 that links to each other with cavity of resorption 3 suction tude 6 adopts horn-like design, itself and housing 10 inwall cooperation places fit like a glove, rubber sleeve 7 adopts thickness design simultaneously, the thickness of the large end 9 at close housing 10 inwall places is thinner than the thickness of small end 8, and this design can reduce refrigeration agent leakage herein.
As shown in Figure 3, the mouth of pipe 16 of sucking pipe 11 protrudes the inwall of housing 10, is inhaled in the refrigerator system thereby can reduce refrigeration oil.Described sucking pipe 11 place's housings 10 can also be set to inwardly be provided with boss, are inhaled in the refrigerator system to reduce refrigeration oil.
The above; it only is the better embodiment of the utility model; but the utility model protection domain is not limited to this, is equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
