Background technology
The combined type air-breathing muffler of aforementioned refrigeration compressor be also referred to as " Combined type refrigerating compressor inhale,
Muffler "（It is the same below）.As is known in the industry, on reciprocating hermetic refrigeration compressor（Generally on cylinder block）And
Different positions is matched in the different location of cylinder block respectively is connected to an air suction silencer and a muffler, specifically,
The refrigeration compressor inlet chamber accent of air suction silencer and refrigeration compressor（Air inlet on i.e. aforementioned cylinder block）Mating, and arrange
The refrigeration compressor discharge chamber accent of gas muffler and refrigeration compressor（Exhaust outlet on i.e. aforementioned cylinder block）Mating.
And then as is known in the industry, cylinder sucks refrigerant gas by air suction silencer when refrigeration compressor works, by inhaling
Gas muffler not only plays the heat effect to refrigerant when weakening compressor inner heat, but also plays reduction refrigerant gas flow
The noise caused by pressure fluctuation and vibration in the process, to help to reduce the running noises of compressor, while can be effective
Ground improves the working efficiency of compressor, that is, improves the Energy Efficiency Ratio of refrigeration compressor（COP）.It follows that air suction silencer is mesh
Preceding reciprocal enclosed refrigeration compressor essential and be more important one of accessory；Still as is known in the industry, system
Cylinder is discharged gas by muffler and plays the work of reduction exhaust noise by muffler when cold compressor works
With because refrigeration compressor exhaust noise is the important sources of total noise of centrifuge.It follows that muffler is equally past at present
Multiple enclosed refrigeration compressor essential and be more important one of accessory.
It is no lack of the technical information about air suction silencer of refrigeration compressor in disclosed Chinese patent literature, slightly to enumerate
Such as CN2663663Y（Muffler shell）、CN2705629Y（Muffler）、CN2733037Y（Hermetically sealed compressor air-breathing

Consider：First, since aforementioned inlet chamber accent and discharge chamber accent being opened on the aforementioned cylinder block of refrigeration compressor
Different position；Second is that for the temperature difference factor that there is great disparity between the suction system and exhaust system of refrigeration compressor, i.e.,
Exhaust system temperature is significantly higher than suction system temperature, then if the inlet and outlet chamber accent of refrigeration compressor is designed at together
Although the rational position in a region can reduce the difficulty of processing of cylinder block and improve processing efficiency or even save processing cost,
It is that heat can be passed during the high-temperature gas that exhaust system is discharged is by way of muffler and is discharged by muffler
Air suction silencer is passed, to make the temperature of refrigeration compressor inner chamber gas increase, influences the raising of refrigerant compression engine efficiency, most
The expectation service life of refrigeration compressor is undermined eventually.It follows that aforementioned structure design belongs to caving-in bash, and from surface

It is designed to separate structure, or since the inlet and outlet temperature difference is greatly and in order to avoid muffler transfers heat to suction
Gas muffler and inlet and outlet chamber accent can only be in different positions.Since causality above-mentioned is for a long time by industry
Approve and receive, thus be showed no in China and foreign countries' patent disclosed so far and non-patent literature it is all by air suction silencer with
The technical information that muffler is combined with each other, while the inlet and outlet chamber accent on the cylinder block of refrigeration compressor being caused to stick to
It maintains always to established practice and is respectively at the different location i.e. present situation of different zones, i.e., whether air suction silencer or exhaust disappear
The structure design of sound device does not give the design of the cylinder block of optimization refrigeration compressor to play the role of positive enlightenment.
In addition, air suction silencer and muffler are formed separate component, at least there is also following shortcomings：Its
One, since air suction silencer has air suction silencer gas outlet, which need to be with the inlet chamber on cylinder block
Accent be coupled, and due to muffler have muffler air inlet, the muffler air inlet need to on cylinder block
The mating of outlet chamber accent, thus match around the boundary line is more, and the probability of gas leakage is also relatively high, once and gas leakage can influence refrigerant compression
The efficiency of machine, and will increase noise；Second, since inlet and outlet muffler is separate construction, thus on the one hand because needing
Make respectively and increase cost, another aspect high material consumption and be unfavorable for economizing on resources；Third, due to inlet and outlet muffler
For separate component, thus the set-up time is long, is unfavorable for saving labor cost；Fourth, since the mold amount of coming into operation is more, from
And it can significantly raise manufacturing expense.
For above-mentioned prior art, the applicant has made lasting and beneficial exploration and has carried out the examination of non-finite number of time
It tests, forms technical solution described below finally.
