Alternatively, described air inlet pipe extends along the axis direction of described noise reduction chamber.
Alternatively, described noise reduction chamber includes barrel and is respectively arranged at two end caps at described barrel two ends, and offers hole on each described end cap；Described air inlet pipe is installed on the described hole of a described end cap.
Alternatively, length is described noise reduction chamber length the 3/4 to 10/11 of the pipeline section being positioned at described silencing cavity indoor of described air inlet pipe.
Alternatively, described air conditioner muffler also includes: escape pipe, and the axis direction from the edge of the described hole of end cap another described along described noise reduction chamber stretches out.
Alternatively, described air inlet pipe is all equal with the interior diameter of described escape pipe and overall diameter, and the 1/6 to 1/5 of the interior diameter that the interior diameter of described air inlet pipe is described barrel.
Alternatively, 4/5 to 3/2 of the interior diameter that distance is described air inlet pipe between poling hole described in every two adjacent groups.
Alternatively, often organizing in described poling hole, described poling hole is multiple, uniform along the circumferential direction of described air inlet pipe.
According to second aspect of the present utility model, this utility model provides a kind of air-conditioner, described air-conditioner includes compressor, condenser and is arranged on the deafener between described compressor and described condenser, and wherein, described deafener is any of the above-described kind of air conditioner muffler.
Air conditioner muffler of the present utility model and air-conditioner arrange poling hole owing to having many group intervals in air inlet pipe, coolant can be made to flow through the chamber of different length by perforated pipe, so that coolant is suddenlyd change by multiple interfaces, thus the noise of different frequency section can be eliminated, cause good Consumer's Experience.Additionally, the volume of this air conditioner muffler is little, simple in construction, save the space of air-conditioner outdoor unit.
According to below in conjunction with the accompanying drawing detailed description to this utility model specific embodiment, those skilled in the art will understand of the present utility model above-mentioned and other purposes, advantage and feature more.
Accompanying drawing explanation
More of the present utility model specific embodiments are hereinafter described in detail with reference to the accompanying drawings by way of example, and not by way of limitation.Accompanying drawing labelling identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that what these accompanying drawings were not necessarily drawn to scale.In accompanying drawing:
Fig. 1 is the schematic diagram of the air conditioner muffler according to one embodiment of this utility model；
Fig. 2 is the schematic local structural graph of air inlet pipe in air conditioner muffler shown in Fig. 1；
Fig. 3 is the schematic system diagram of the air-conditioner according to one embodiment of this utility model.
Detailed description of the invention
Fig. 1 is the schematic diagram of the air conditioner muffler 130 according to one embodiment of this utility model.As it is shown in figure 1, this utility model embodiment provides a kind of air conditioner muffler 130.Air conditioner muffler 130 generality can include noise reduction chamber 20 and the air inlet pipe 30 of end insertion noise reduction chamber 20.Especially, as in figure 2 it is shown, in this embodiment, the endcapped of air inlet pipe 30, and pipeline section 31 perisporium being positioned at noise reduction chamber 20 of air inlet pipe 30 offers the spaced poling hole 32 of many groups.The axial end often organizing poling hole 32 is in a plane 50 relative to the inclined shape of air inlet pipe 30.Such as, the angle of the axis of this plane 50 and air inlet pipe 30 can be 30 ° to 60 °, concretely 42 °, 45 ° etc..
This air conditioner muffler 130 can make coolant enter noise reduction chamber 20 from the poling hole 32 of difference group, to flow through the chamber of different length at noise reduction chamber 20, thus the sudden change through multiple interfaces of the coolant of entrance noise reduction chamber 20 can be made, can eliminate the noise of different frequency section.Such as, the group number in the poling hole on air conditioner muffler 130 is N, and the flow direction along coolant is followed successively by first group of poling hole, second group of poling hole ..., N group poling hole.If coolant flows out from first group of poling hole, then can eliminate the noise of a frequency band；If coolant flows out from second group of poling hole, then can eliminate the noise of another frequency band；...；If coolant flows out from N group poling hole, then can eliminate the noise of n-th frequency band.That is, often the entrance point of group poling hole and air inlet pipe can form a chamber and (also be understood as often being formed between group poling hole and first group of poling hole a chamber, the chamber formed between first group of poling hole and first group of poling hole is zero), N group poling hole then forms multiple different chamber, and then eliminates the noise of each frequency band.
In embodiments more of the present utility model, noise reduction chamber 20 includes barrel and is respectively arranged at two end caps at barrel two ends.Each end cap offers hole.Air inlet pipe 30 extends along the axis direction of noise reduction chamber 20, and air inlet pipe 30 is installed on the hole of an end cap.This air conditioner muffler 130 may also include escape pipe 40, and it stretches out from the edge of the hole of another end cap along the axis direction of noise reduction chamber 20.
In embodiments more of the present utility model, air inlet pipe 30 is all equal with the interior diameter of escape pipe 40 and overall diameter, and the interior diameter of air inlet pipe 30 is the 1/6 to 1/5 of the interior diameter of barrel.The length of the pipeline section 31 of air inlet pipe 30 is the 3/4 to 10/11 of noise reduction chamber 20 length.4/5 to 3/2 of the interior diameter that distance is air inlet pipe 30 between every two adjacent groups poling hole 32.Often in group poling hole 32: poling hole 32 can be multiple, for instance can be 4, and multiple poling holes 32 are uniform along the circumferential direction of air inlet pipe 30.
Fig. 3 is the schematic system diagram of the air-conditioner according to one embodiment of this utility model.This utility model embodiment additionally provides a kind of air-conditioner, and it can include indoor set and off-premises station.Off-premises station can have compressor 110, condenser 120 and be arranged on the deafener between compressor 110 and condenser 120.Especially, deafener is the air conditioner muffler 130 in any of the above-described embodiment, not only can eliminate the noise of different frequency section, causes good Consumer's Experience, and volume is little, simple in construction, saves the space of air-conditioner outdoor unit.Indoor set can have throttling arrangement 140 and vaporizer 150, with when summer to indoor offer cold, when winter to indoor offer heat.
So far, those skilled in the art will recognize that, multiple exemplary embodiment of the present utility model is illustrate and described although detailed herein, but, when without departing from this utility model spirit and scope, still can directly determine according to this utility model disclosure or derive other variations or modifications many meeting this utility model principle.Therefore, scope of the present utility model is it is understood that cover all these other variations or modifications with regarding as.
