DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0021] It should be noted that when an element is referred to as "arranged on" another element, it can be directly arranged on the other element or there can be a middle element. When an element is referred to as "arranged on" another element, it can be directly arranged on the other element or there can be a middle element. When an element is referred to as "fixed on" another element, it can be directly fixed on the other element or there can be a middle element.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0023] In the prior art, the silencer and the check valve are usually two separate components. The silencer is connected to the check valve through an independent connecting pipe when producing an air conditioner. However, since the silencer, the check valve, and the connecting pipe are all made of copper, a large amount of copper material needs to be consumed by the air conditioner, and with the continuous rise of copper prices, the cost of the air conditioner is also greatly increased.

[0024] Please refer to Figures 1 to 3 The present application provides a silencer assembly, which comprises a silencer 100 and a check valve 200. The silencer 100 comprises a silencer body 10 and an outlet connecting pipe 30 arranged at one end of the silencer body 10. One end of the outlet connecting pipe 30 extends into the silencer body 10, and the other end extends out of the end of the silencer body 10. The end of the outlet connecting pipe 30 extending out of the silencer body 10 is directly welded with the check valve 200.

[0025] Since the outlet connecting pipe 30 is directly welded with the one-way valve 200, that is, the silencer 100 is directly welded with the one-way valve 200, the connecting pipe in the prior art is cancelled, so that the material can be saved, and the production cost can be greatly reduced. In the prior art, since the silencer is connected with the one-way valve through the connecting pipe, there are two welding points between the silencer and the one-way valve: one is the welding point between the silencer and the connecting pipe, and the other is the welding point between the connecting pipe and the one-way valve. In the present application, since the silencer 100 is directly connected with the one-way valve 200, there is only one welding point between the silencer 100 and the one-way valve 200. That is, compared with the prior art, the silencer assembly of the present application reduces the welding points. When there are many welding points, multiple welding is required during processing, the process is more complex, and the production efficiency is low. Moreover, the welding position is prone to leakage, and the probability of leakage is higher when there are multiple welding points. The silencer assembly of the present application reduces the welding points, so that the processing process is simplified, the production efficiency is improved, the probability of leakage at the welding position is reduced, and the reliability of the connection between the silencer 100 and the one-way valve 200 is improved. Moreover, since one connecting piece is omitted, the overall length of the silencer assembly is shortened, which is beneficial to save space and facilitate the installation of the silencer assembly in the air conditioner.

[0026] The one end of the outlet connecting pipe 30 extends into the silencer body 10, increases the flow path of the refrigerant medium in the silencer body 10, and thus can buffer the flow of the refrigerant medium, so as to be beneficial to reduce the noise generated by the flow of the refrigerant medium, and make the silencer body 10 have better silencing effect.

[0027] The silencer body 10 includes a body part 13, and the two ends of the body part 13 are respectively shrunk to form an inlet end 12 and an outlet end 11, so that the inner diameters of the inlet end 12 and the outlet end 11 are smaller than the inner diameter of the body part 13. After the refrigerant medium enters the body part 13 from the inlet end 12, the flow rate of the refrigerant medium is reduced due to the increase of the inner diameter, that is, the refrigerant medium is buffered, so as to be able to reduce the noise generated by the flow of the refrigerant medium.

[0028] In the present application, the outlet connecting pipe 30 is connected to the outlet end 11 of the silencer body 10. That is, the one-way valve 200 is connected to one side of the outlet end 11 of the silencer body 10, so that the refrigerant medium can only flow from the silencer 100 to the one-way valve 200 by setting the one-way valve 200, but cannot flow from the one-way valve 200 to the silencer 100. Moreover, since one end of the outlet connecting pipe 30 extends into the silencer body 10, the refrigerant medium flowing into the silencer body 10 will not directly flow out of the outlet end 11, but will first flow to the outlet end 11, be bounced by the inner wall of the silencer body 10, and then flow to the one end of the outlet connecting pipe 30 extending into the silencer body 10, and finally flow out of the silencer 100 through the outlet connecting pipe 30. Figure 1As shown in the figure, the curved line with arrow in the figure is a flow path schematic diagram of the refrigerant medium in the muffler body 10. In this way, the flow path of the refrigerant medium in the muffler body 10 is increased, so that the flow of the refrigerant medium can be buffered, and thus the noise generated by the flow of the refrigerant medium can be reduced, so that the muffler 100 has better muffling effect.

[0029] Further, the length of the part of the outlet pipe 30 extending into the muffler body 10 is A, and the total length of the muffler body 10 is B, which satisfies: A≥1 / 2B. The longer the length of the part of the outlet pipe 30 extending into the muffler body 10, the longer the flow path of the refrigerant medium in the muffler body 10, and the stronger the buffering effect on the refrigerant medium, so that the muffling effect is better. In this embodiment, A≥1 / 2B, so that the flow path of the refrigerant medium in the muffler body 10 is longer, so that the muffler body 10 has better muffling effect.

[0030] The one end of the outlet pipe 30 extending out of the muffler body 10 forms a flared end 31, and one end of the one-way valve 200 is inserted into the flared end 31. The flared end 31 is formed by machining the one end of the outlet pipe 30, and the one-way valve 200 and the outlet pipe 30 can be connected by matching the flared end 31 with the one end of the one-way valve 200, without machining the end of the one-way valve 200. The process of flaring the one end of the outlet pipe 30 is relatively simple and easy to process, which is conducive to improving the production efficiency of the muffler assembly.

[0031] Further, the muffler body 10 is made of stainless steel, the outlet pipe 30 is made of copper, and the one-way valve 200 is made of copper. The stainless steel has good rigidity and is inexpensive, so that the use of stainless steel for the muffler body 10 can greatly reduce the cost of the muffler assembly. The outlet pipe 30 made of copper facilitates the direct connection of the muffler 100 and the one-way valve 200 made of copper.

[0032] The muffler assembly further comprises a first stainless steel pipe 40, which is directly connected to the inlet end 12, or indirectly connected to the inlet end 12 through a copper connecting piece. The two cases will be described in detail below.

[0033] Please refer to Figure 3 As shown in the figure, in one embodiment, the first stainless steel pipe 40 is directly connected to the inlet end 12. Since the muffler body 10 is made of stainless steel, the first stainless steel pipe 40 is also made of stainless steel, so the welding between the first stainless steel pipe 40 and the inlet end 12 is the welding between stainless steel and stainless steel, and thus the furnace brazing method can be used to weld the first stainless steel pipe 40 and the inlet end 12. The first stainless steel pipe 40 is directly connected to the inlet end 12, and the welding method is simple and easy to process.

[0034] Further, the inner wall of the inlet end 12 is provided with an inner step 121, and the first stainless steel pipe 40 extends into the inlet end 12 and is welded to the inner step 121. The inner step 121 limits the length of the first stainless steel pipe 40 extending into the inlet end 12, which greatly facilitates the assembly of the first stainless steel pipe 40 before welding and is conducive to simplifying the processing procedure.

[0035] Please refer to Figure 4 As shown in the drawings, in another embodiment, the first stainless steel pipe 40 is indirectly connected to the inlet end 12 through a copper connecting piece. Specifically, the copper connecting piece includes a first copper sleeve 60 connected to the inlet end 12 and a second copper sleeve 70 connected to the first stainless steel pipe 40, and the first copper sleeve 60 is welded to the second copper sleeve 70. In this way, the muffler body 10 and the first copper sleeve 60 can be welded together first, and the first stainless steel pipe 40 and the second copper sleeve 70 can be welded together, and then the first copper sleeve 60 and the second copper sleeve 70 can be welded together, thereby realizing the connection between the muffler body 10 and the first stainless steel pipe 40. The muffler body 10 and the first copper sleeve 60 are welded by furnace brazing, the first stainless steel pipe 40 and the second copper sleeve 70 are welded by furnace brazing, and the first copper sleeve 60 and the second copper sleeve 70 are welded by flame brazing. Because the first copper sleeve 60 and the second copper sleeve 70 are provided, the muffler body 10 and the first copper sleeve 60 can be furnace brazed first, and the first stainless steel pipe 40 and the second copper sleeve 70 can be furnace brazed, so that the length of the pipe entering the brazing furnace is shorter, multiple pipes can be furnace brazed at the same time, the operation is more convenient, and the production efficiency is improved. Moreover, the muffler body 10 and the first stainless steel pipe 40 are connected through the first copper sleeve 60 and the second copper sleeve 70, and the first copper sleeve 60 and the second copper sleeve 70 can be welded by flame brazing. When the muffler body 10 needs to be replaced, the muffler body 10 can be removed from the air conditioner by only damaging the connection between the first copper sleeve 60 and the second copper sleeve 70. Then, a new muffler body 10 can be welded to the second copper sleeve 70. Therefore, the copper connecting piece makes it very convenient to replace the muffler body 10 in the air conditioner.

[0036] Further, the first copper sleeve 60 is sleeved on the outside of the inlet end 12. Specifically, the outer wall of the inlet end 12 is provided with an outer step 122, so that the assembly position of the first copper sleeve 60 is limited by the outer step 122, which greatly facilitates the assembly of the first copper sleeve 60 and the inlet end 12 of the muffler body 10 before welding. The second copper sleeve 70 is sleeved on the outside of one end of the first stainless steel pipe 40, which is convenient to assemble. The first copper sleeve 60 is sleeved on the outside of the second copper sleeve 70, which greatly facilitates the flame brazing between the first copper sleeve 60 and the second copper sleeve 70.

[0037] When the first copper sleeve 60 and the second copper sleeve 70 are flame brazed, the position of the welding torch is deviated to the first copper sleeve 60, so that heat can be transferred to the first stainless steel pipe through the second copper sleeve 70, thereby avoiding overburning and damaging the welding seam between the muffler body 10 and the first copper sleeve 60.

[0038] The wall thickness of the first copper sleeve 60 is greater than that of the second copper sleeve 70. In this way, the structural strength of the connection between the muffler body 10 and the first stainless steel pipe 40 can be improved.

[0039] Please refer to Figure 1 Further, the muffler assembly further comprises a second stainless steel pipe 50, one end of the second stainless steel pipe 50 is connected with a third copper sleeve 80, and the third copper sleeve 80 is connected to the one-way valve 200 away from the muffler 100. The second stainless steel pipe 50 is arranged to facilitate the connection of the muffler assembly with other pipe fittings in the air conditioner. In the embodiment, the third copper sleeve 80 is sleeved outside the second stainless steel pipe 50, and one end of the third copper sleeve 80 extends into the one-way valve 200 and is welded with the one-way valve 200. In the production and processing of the muffler assembly, the third copper sleeve 80 and the second stainless steel pipe 50 are first brazed in the furnace, and the third copper sleeve 80 is welded to one end of the second stainless steel pipe 50, and then the third copper sleeve 80 is welded to the one-way valve 200 away from the muffler 100 by flame brazing.

[0040] The application also provides an air conditioner comprising the muffler assembly of any one of the above embodiments. Since one end of the outlet pipe 30 extends into the muffler body 10, the flow path of the refrigerant medium in the muffler body 10 is increased, thereby buffering the flow of the refrigerant medium, which is conducive to reducing the noise generated by the flow of the refrigerant medium, so that the muffler body 10 has better muffling effect. Since the outlet pipe 30 is directly welded with the one-way valve 200, that is, the muffler 100 is directly welded with the one-way valve 200, which is equivalent to canceling the connecting pipe in the prior art, so that the material can be saved, thereby greatly reducing the production cost. Moreover, since the muffler 100 and the one-way valve 200 are directly connected, there is only one welding point between the muffler 100 and the one-way valve 200. That is, compared with the prior art, the muffler assembly of the application reduces the welding points. In this way, the processing technology is simplified, the production efficiency is improved, the probability of leakage at the welding point is reduced, and the reliability of the connection between the muffler 100 and the one-way valve 200 is improved. Moreover, since one connecting piece is omitted, the overall length of the muffler assembly is shortened, which is conducive to saving space and facilitating the installation of the muffler assembly in the air conditioner.

[0041] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they should be considered to fall within the scope of the present specification.

[0042] Those skilled in the art should know that the above-described embodiments are only used to illustrate the present application, but not as a limitation to the present application, and as long as the changes and variations of the above-described embodiments are within the spirit of the present application, they should be considered to fall within the scope of the present application.
