Description
Technical Field
The utility model belongs to the technical field of the air conditioner technique and specifically relates to an interior intubate muffler and air conditioner thereof is related to.
Background
The pressure of the refrigerant is changed by the periodic discharge action of the compressor to generate pressure pulsation, and the pressure pulsation is transmitted from the compressor along the pipeline. To solve this problem, a silencer is installed in the piping system, as shown in fig. 1. In order to improve the noise cancellation effect, the ratio of the sectional areas of the pipe and the muffler body needs to be increased, which results in an excessively large muffler body. In order to solve this problem, the length and thickness of an insertion pipe inserted into the muffler main body are generally changed to improve the sound-deadening property, and as disclosed in patent No. CN205137838U, the inner diameter of the muffler inserted into the inlet pipe of the muffler main body on the front end side is smaller than the inner diameter of the inlet pipe on the upstream side of the front end side. As shown in fig. 2. But this solution results in a large pressure loss.
SUMMERY OF THE UTILITY MODEL
The utility model provides an interior intubate muffler and air conditioner thereof not only is showing the noise elimination characteristic that has improved the muffler, moreover very big reduction the loss of pressure that the muffler produced.
The utility model discloses a technical scheme is realized like this: an interpolation pipe silencer comprises a silencer cylinder body, wherein the silencer cylinder body is provided with an inlet side opening and an outlet side opening, an inlet distribution pipe matched with an air conditioner distribution pipe is installed in the inlet side opening, an outlet insertion pipe is installed in the outlet side opening, the outlet insertion pipe sequentially comprises an outlet insertion pipe first diameter portion, an outlet insertion pipe variable diameter portion and an outlet insertion pipe second diameter portion which are arranged into a whole, the diameter of the outlet insertion pipe first diameter portion is larger than that of the outlet insertion pipe second diameter portion, the outlet insertion pipe first diameter portion and the outlet insertion pipe variable diameter portion are arranged inside the silencer cylinder body, and the outlet insertion pipe second diameter portion penetrates through the outlet side opening and stretches out of the silencer cylinder body.
As a preferable technical solution, a silencer cylinder diameter-changing portion is respectively provided between the silencer cylinder and the inlet-side opening and the outlet-side opening.
Preferably, the inlet pipe is a straight pipe.
The utility model discloses a another technical scheme is realized like this: the air conditioner comprises a compressor, and the inner insertion pipe silencer is arranged on a connecting pipeline of the compressor.
By adopting the technical scheme, the beneficial effects of the utility model are that: because export insert tube is including setting up first footpath of export insert tube, export insert tube variable diameter portion and export insert tube second footpath as an organic whole in proper order, the diameter of the first footpath of export insert tube is greater than the diameter of export insert tube second footpath, and the first footpath of export insert tube and export insert tube variable diameter portion set up inside the muffler barrel, and export insert tube second footpath passes the outlet side and uncovered and stretch out the muffler barrel is outside, and the muffler export insert tube of this patent is the flaring structure, makes muffler export diameter be greater than the entry diameter, improves the acoustics characteristic of muffler, reduces the pressure loss of refrigerant simultaneously.

FIG. 2 is a schematic view of another muffler configuration;
FIG. 3 is a schematic structural view of the present invention;
FIG. 4 is a comparative graphical representation of muffling characteristics;
wherein: 1. an inlet pipe; 2. a muffler cylinder; 3. an outlet insertion tube; 3-1, an outlet insertion tube first diameter portion; 3-2, inserting the outlet into the pipe diameter-variable part; 3-3, a second diameter part of the outlet insertion pipe; 4. the inlet side is open; 5. the outlet side is open; 6. the silencer barrel becomes footpath.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example one
As shown in fig. 3, an inner intubation silencer comprises a silencer cylinder 2, the silencer cylinder 2 has an inlet opening 4 and an outlet opening 5, an inlet piping 1 adapted to an air conditioner piping is installed in the inlet opening 4, an outlet insertion tube 3 is installed in the outlet opening 5, the outlet insertion tube 3 sequentially comprises an outlet insertion tube first diameter portion 3-1, the diameter of the first diameter part 3-1 of the outlet insert pipe is larger than that of the second diameter part 3-3 of the outlet insert pipe, the first diameter part 3-1 of the outlet insert pipe and the diameter of the diameter part 3-2 of the outlet insert pipe are arranged inside the cylinder body 2 of the silencer, and the second diameter part 3-3 of the outlet insert pipe penetrates through the outlet side opening 5 and extends out of the cylinder body 2 of the silencer.
Further, a silencer cylinder diameter-changing portion 6 is provided between the silencer cylinder 2 and the inlet-side opening 4 and the outlet-side opening 5, respectively, and the inlet pipe 1 is a straight pipe.
Example two
The air conditioner comprises a compressor, and the inner insertion pipe silencer is arranged on a connecting pipeline of the compressor.
The first diameter part 3-1 of the outlet insertion pipe is arranged in the silencer cylinder 2, when the air-conditioning refrigerant flows into the silencer cylinder 2 through the inlet pipe 1, as shown in the flowing direction of fig. 3, when the air-conditioning refrigerant passes through the outlet insertion pipe 3, the air-conditioning refrigerant firstly passes through the first diameter part 3-1 of the outlet insertion pipe, the diameter of the first diameter part of the outlet insertion pipe needs to be larger than that of the inlet pipe 1, and at this time, the silencer with a small inlet and a large outlet is formed, so that the silencing quantity of the silencer can be effectively improved, and the pressure loss of the refrigerant passing through the silencer is reduced due to the larger outlet diameter. The diameter of the second diameter part 3-3 of the outlet insertion pipe is determined by the pipe diameter of the air-conditioning pipe, so that the inlet and outlet pipe of the silencer can be directly connected with the air-conditioning pipe without redesigning the air-conditioning pipe.
The acoustic characteristics of the silencer are simulated and analyzed aiming at the silencer model in the embodiment, and compared with the existing silencer structure, as shown in fig. 4, the acoustic characteristics of the silencer are effectively improved, wherein the horizontal axis is silencing frequency Hz, and the vertical axis is silencing quantity dB.
