Description
Technical field
The invention belongs to refrigeration compressor accessory technical field, be specifically related to a kind of modular air suction silencer of refrigeration compressor.
Background technique
As the industry's knowledge of the reason; reciprocal hermetically sealed refrigerating compressor unit can install an air suction silencer therein usually; during refrigeration compressor work, cylinder sucks refrigerant gas by air suction silencer; by air suction silencer both played weaken compressor inner heat time refrigeration agent heat effect; play again the noise and vibration reducing and caused by pressure pulsation in refrigerant gas flow process; thus contribute to the running noises reducing compressor; effectively can improve the working efficiency of compressor simultaneously, namely improve the Energy Efficiency Ratio (COP) of refrigeration compressor.It can thus be appreciated that air suction silencer is the requisite of reciprocal hermetically sealed refrigerating compressor unit at present and is one of accessory of outbalance.
Just because of air suction silencer, there is aforesaid good effect, therefore the concern of industry is received all the time, structural system as air suction silencer of refrigeration compressor mainly comprises housing, cap, intakeport and relief opening, and this structure can be seen in a large number in disclosed Chinese patent literature.Wherein: contribute to the patent of sealing, assembling capacity and the fiting effect improved between cap and housing as CN2663663Y(muffler shell), CN2705629Y(baffler), the cap of CN101487461B(air suction silencer of refrigeration compressor and the cooperating structure of housing), CN101545472B(air suction silencer of refrigeration compressor), the air suction silencer of CN101545473B(refrigeration compressor) and CN201386641Y(air suction silencer of refrigeration compressor), etc.; Be conducive to promoting erasure effect namely reduce so that eliminates air suction and noise and reduction inhalation resistance patent as CN2886124Y(Semi-direct suction muffler for refrigeration compressor), CN201165957Y(air suction sound eliminator for refrigeration compressor), CN201306287Y(hermetically sealed compressor air suction silencer), CN102720653B(compressor air suction silencer), the air suction silencer of CN102720654B(refrigeration compressor) and CN102720655B(air suction silencer of refrigeration compressor), etc.
Extend sucking pipe (i.e. connecting vessels, as follows) path for reduce refrigeration compressor suction noise, improve erasure effect there is positive effect, and become the common recognition of industry, but can have an impact to the COP of refrigeration compressor and receive the concern of industry simultaneously.Because the technical measures extending the first-selection in the path of sucking pipe are at present generally sucking pipe is designed to tortuous changeable form, and why sucking pipe are designed to tortuous changeable form, are because be subject to the restriction of housing volume, are namely subject to the restriction in housing chamber.It can thus be appreciated that for cost exchanges the erasure effect of expectation for, what is gained is more than what is lost with the COP sacrificing refrigeration compressor.Certainly, these three patents of aforementioned invention Authorization Notice No. CN102720653B, CN102720654B and CN102720655B(propose by the applicant) be have an impact to the COP of refrigeration compressor between both in the path and avoiding extending sucking pipe to have found rational equinoctial point, but to there is housing and shell cover structure relative complex and be used in the mould complexity making housing and cap be its shortcoming.
Authorization Notice No. CN2833127Y recommends to be had " New Energy-saving Deadender Of Closed Refrigerant Motor-compressor ", this patent formula is by housing, an overall cap is connected into by link and housing, be formed in the honeycomb duct (i.e. intakeport) on the sidewall of housing, be formed in the throttle pipe (i.e. air outlet) on cap and be arranged in housing for the cavity that housing and cap are formed be divided into upper silencing cavity and lower silencing cavity and the connecting vessels being provided with silencing net up form, the technological points of this patent is: build a little cavity volume on the top of connecting vessels, by this little cavity volume as middle silencing cavity, a connecting pipe is extended in the bottom of connecting vessels, this connecting tube is corresponding with the honeycomb duct air outlet of honeycomb duct with under the state that honeycomb duct keeps certain intervals, specifically can see the 2nd page last two sections, the specification text of this patent.Read known by the full text of the specification to this patent: because it is installed on housing in when assembling using the connecting tube being essentially sucking pipe as independently parts, thus there is certain modularization effect, and to a certain extent can simplified structure and simplify manufacture mould.But there is following shortcoming: one, because whole connecting vessels (being essentially sucking pipe) is in being tending towards without tortuous structure, thus path is restricted (namely path is shorter) and is difficult to embody the erasure effect expected; Its two, due to connecting vessels bottom extend connecting tube and honeycomb duct between there is spacing, thus the inspiratory effects of honeycomb duct is subject to corresponding impact, and connecting vessels can not be made to give full play to due noise reduction; They are three years old, due to connecting vessels and extend connecting vessels bottom connecting tube be all unsupportedly tending towards vertical cantilever position in not only indefinite, thus when refrigeration compressor works, the pressure pulsation that refrigerant gas flow produces can make whole connecting vessels occur not wishing to occur but unavoidable severe vibration situation, even damages; Its four, patent not to be realized ideal the enlightenment sealed between the two to send as an envoy to cap and housing, but the quality of sealing effect between cap and housing can see patents such as aforementioned CN2663663Y, CN2705629Y, CN101487461B and CN201386641Y.
The connecting vessels of shape substantially in C font not only can play good sound deadening to a certain extent but also not show the impact of the COP caused refrigeration compressor, this structure can be seen in equally in disclosed Chinese patent literature, typical " the hermetically sealed compressor air suction silencer " provided as Authorization Notice No. CN2733037Y, this patent formula is for aforementioned CN2833127Y, except making erasure effect except changing the shape of connecting vessels into hook-type and making moderate progress, still there is the aforementioned shortcoming of CN2833127Y.
More typical such as world patent WO2006/116830(English) " air suction silencer for refrigeration compressor " introduced, this patent application scheme describes two specific embodiment structures, wherein, the honeycomb duct of second example structure is because have employed a gas inlet tube and two gas outlet pipes, and make the gas access of first gas outlet pipe be positioned at the silencing cavity communicated with the exhaust port of gas inlet tube be separated out in the housing chamber of housing by dividing plate, and the gas outlet of this first gas outlet pipe is insinuated into be separated out in the housing chamber of housing by dividing plate and in another silencing cavity communicated with the gas access of second gas outlet pipe.The middle part of the connecting vessels of hook-type, in fact for aforementioned CN2733037Y, disconnects by this structure, thus except same shortcoming of depositing CN2833127Y, also add manufacture and assembling difficulty.
For above-mentioned prior art, still have the necessity improved further, for this reason the applicant do positive and lasting exploration with repeatedly design and done the test of non-limited number of times, result proves practicable, and technological scheme described below produces under this background.
