The noise that compressor of air conditioner produces is after compressor body and connecting line, the noise of medium-high frequency is many easily to be slowed down, remaining is mainly low frequency exhaust noise, secondary is intermediate frequency exhaust noise, low frequency and part intermediate frequency exhaust noise are passed to indoor by coolant media, and the use sense affecting user is subject to.
The noise reduction means of current use increases silencer exactly in air conditioner piping system, and wherein single expansion tube silencer is simple and easy and the most general silencer, but the noise reduction of this silencer is not very desirable.Technical problem to be solved in the utility model is by the basis of existing silencer, the structure of muffler is done corresponding improvement, improves the noise reduction of silencer.
The muffler 100 according to the utility model embodiment is described in detail below in conjunction with Fig. 1 to Fig. 5.
According to the muffler 100 of the utility model embodiment, housing 1 can be comprised, housing 1 is provided with air inlet pipe 2 and escape pipe 3, air inlet pipe 2 is connected with compressor by connecting line, the noise that compressor produces is after compressor and connecting line, and medium-high frequency noise is wherein many easily to be alleviated, and remaining is mainly low frequency exhaust noise, secondary is intermediate frequency exhaust noise, and the muffler 100 in the utility model embodiment can eliminate medium and low frequency noise.
As shown in Figure 1 to Figure 3, air inlet pipe 2 is arranged on one end of housing 1, and escape pipe 3 is arranged on the other end of housing 1, air inlet pipe 2 and escape pipe 3 eccentric setting.That is, the center line of air inlet pipe 2 and the center line of escape pipe 3 are not what overlap, but depart from certain distance.
Thus, by by air inlet pipe 2 and escape pipe 3 eccentric setting, after making the sound of medium and low frequency enter housing 1, directly can not pass housing 1, but the bottom that can collide housing 1 is reflected, thus increase the order of reflection of noise in muffler 100, superposed with continuous between back wave by the straight ripple of noise, make noise obtain certain elimination.Utilize the principle of dissipative muffler, when sound wave enters into silencer, a part of acoustic energy, when colliding the tube wall of escape pipe 3, is consumed due to friction, makes to be weakened by the sound wave of muffler 100 simultaneously.
According to the silencer of the utility model embodiment, by by air inlet pipe 2 and escape pipe 3 eccentric setting, increase the number of times that noise superposes in the reflection of the inwall of silencer, and then the noise making compressor produce is cut down to a certain extent, alleviate the noise transmission of compressor operation generation to indoor phenomenon, the use sense improving user is subject to.
According to embodiments more of the present utility model, between the center line of air inlet pipe 2 and the longitudinal center line of housing 1, there is the first distance M.
Particularly, the span of the ratio of the length of the first distance M and housing 1 is: 1:10 ~ 1:15.
In embodiments more of the present utility model, between the center line of escape pipe 3 and the longitudinal center line of housing 1, there is second distance N.
Particularly, the span of the ratio of the length of second distance N and housing 1 is: 1:10 ~ 1:15.
First Distance geometry second distance can be equal, first Distance geometry second distance also can be unequal, as long as ensure that the first distance is 1:10 ~ 1:15 with the span of the ratio of the length of housing 1, the span of the ratio of the length of second distance and housing 1 is 1:10 ~ 1:15.
Further, air inlet pipe 2 and escape pipe 3 are distributed in the both sides of the axis centre line of housing 1.Thus, make when the first distance M and second distance N is certain, the center line of air inlet pipe 2 and the distance between center line of escape pipe 3 are farthest, and then the further number of times increasing noise and superpose in the reflection of the inwall of silencer, alleviate the noise transmission of compressor operation generation to indoor phenomenon, the use sense improving user is subject to.
Alternatively, the diameter of air inlet pipe 2 is 8% ~ 15% of the length of housing 1, and the diameter of escape pipe 3 is 8% ~ 15% of the length of housing 1.
Further, housing 1, air inlet pipe 2 and escape pipe 3 are formed in one part.Thus, make muffler 100 structure simple, handling ease, and then the production efficiency that improve muffler 100.
Certainly, be understandable that, housing 1, air inlet pipe 2 and escape pipe 3 can also be independent workpiece, and housing 1, air inlet pipe 2 and escape pipe 3 are linked together by modes such as bondings.
There is provided one below according to the preferred embodiment of silencer of the present utility model.
As shown in Figure 3, the distance of the center line of air inlet pipe 2 and the longitudinal center line of housing 1 (namely, first distance M) be 5mm, air inlet pipe 2 and escape pipe 3 are all for internal diameter is 8mm round tube, the length of air inlet pipe 2 and escape pipe 3 is 6mm, and air inlet pipe 2 and escape pipe 3 form for directly pulling out mouth on housing 1; It is 20mm that housing 1 is formed as internal diameter, and length is the cylindrical of 60mm.
The simple air-conditioner outdoor unit 200 described according to the utility model embodiment below.
According to the air-conditioner outdoor unit 200 of the utility model embodiment, comprise the muffler 100 of above-described embodiment, owing to being provided with above-mentioned muffler 100 according to the air-conditioner outdoor unit 200 of the utility model embodiment, the noise that air-conditioner outdoor unit 200 is produced obtains abatement to a certain extent, alleviate noise transmission to indoor phenomenon, the use sense improving user is subject to.
In the description of this description, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, to the schematic representation of above-mentioned term not must for be identical embodiment or example.And the specific features of description, structure, material or feature can combine in one or more embodiment in office or example in an appropriate manner.In addition, when not conflicting, the feature of the different embodiment described in this description or example and different embodiment or example can carry out combining and combining by those skilled in the art.
