Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to a silencer assembly and an air conditioner. BACKGROUND

[0002] In an air conditioner, a silencer and a check valve are generally two separate components, and in the production of an air conditioner, the silencer is usually connected to the check valve through an independent connecting pipe. However, since the silencer and the check valve are usually made of copper, and the connecting pipe is also made of copper. As a result, the air conditioner consumes a large amount of copper material, and with the continuous rise in copper prices, the cost of the air conditioner is also greatly increased. SUMMARY

[0003] Therefore, it is necessary to provide a silencer assembly and an air conditioner which can reduce the use of materials and reduce production costs.

[0004] The present application provides a silencer assembly, comprising a silencer and a check valve, the silencer comprising a silencer body and an interface pipe arranged at one end of the silencer body, the interface pipe being directly connected to the check valve.

[0005] In one embodiment, the silencer body is made of stainless steel, the interface pipe is made of copper, and the check valve is made of copper.

[0006] In one embodiment, the silencer body has an outlet end, the interface pipe is sleeved outside the outlet end and welded with the outlet end, and one end of the check valve extends into the interface pipe and is directly welded with the interface pipe.

[0007] In one embodiment, the end of the check valve extending into the interface pipe abuts against the end face of the outlet end.

[0008] In one embodiment, the outer wall of the outlet end is provided with a first outer step, the first outer step is arranged along the circumference of the outlet end, and the interface pipe is sleeved at the first outer step.

[0009] In one embodiment, the silencer body has an inlet end, and the silencer assembly further comprises a first stainless steel pipe, the first stainless steel pipe being directly connected to the inlet end, or the first stainless steel pipe being indirectly connected to the inlet end through a copper connecting piece.

[0010] In one embodiment, the copper connecting piece comprises a first copper sleeve connected to the inlet end and a second copper sleeve connected to the first stainless steel pipe, and the first copper sleeve is welded with the second copper sleeve.

[0011] In one embodiment, the first copper sleeve is fitted onto the outside of the inlet end, and the second copper sleeve is fitted onto the outside of one end of the first stainless steel pipe, with the first copper sleeve fitted onto the outside of the second copper sleeve.

[0012] In one embodiment, the wall thickness of the first copper sleeve is greater than the wall thickness of the second copper sleeve.

[0013] In one embodiment, the muffler assembly further includes a second stainless steel tube, one end of which is connected to a third copper sleeve, the third copper sleeve being connected to the end of the one-way valve away from the muffler.

[0014] The present invention also provides an air conditioner including the silencer assembly described above.

[0015] The muffler assembly and air conditioner provided by this invention, since the muffler includes a muffler body and an interface pipe located at one end of the muffler body, and the interface pipe is directly connected to a one-way valve, that is, the muffler and the one-way valve are directly connected, which is equivalent to eliminating the connecting pipe in the prior art. This saves materials and thus greatly reduces production costs. Because the muffler and the one-way valve are directly connected, there is only one weld point between the muffler and the one-way valve. In other words, compared with the prior art, the muffler assembly of this application reduces the number of weld points, thereby simplifying the processing technology, improving production efficiency, reducing the probability of leakage at the weld, and improving the reliability of the connection between the muffler and the one-way valve. Furthermore, since one connecting component is eliminated, the overall length of the muffler assembly is shortened, which helps save space and facilitates the installation of the muffler assembly in the air conditioner.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to 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 of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] It should be noted that when an element is referred to as being "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 being "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 being "fixed on" another element, it can be directly fixed on the other element or there can be a middle element.

[0023] 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 the present application belongs. The terminology used in the description of the present application only for the purpose of describing specific embodiments and is not intended to limit the present application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] In the prior art, the muffler and the check valve are generally two components arranged separately. In the production of air conditioners, the muffler is usually connected to the check valve through an independent connecting pipe. However, since the muffler and the check valve are usually made of copper, and the connecting pipe is also made of copper. As a result, a large amount of copper material is consumed by the air conditioner. With the continuous rise of copper prices, the cost of the air conditioner is also greatly increased.

[0025] Please refer to Figures 1 to 3The application provides a silencer assembly, which comprises a silencer 100 and a one-way valve 200. The silencer 100 comprises a silencer body 10 and an interface pipe 30 arranged at one end of the silencer body 10, and the interface pipe 30 is directly connected with the one-way valve 200. In this way, the silencer 100 is directly connected 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, 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, i.e., a welding point between the silencer and the connecting pipe and a welding point between the connecting pipe and the one-way valve. However, in the 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 to say, compared with the prior art, the silencer assembly of the application reduces the welding points. When there are many welding points, multiple welding needs to be performed during processing, the process is relatively complex, and the production efficiency is low; and the welding position is prone to leakage, and the probability of leakage is higher when there are multiple welding points. Since the silencer assembly of the application reduces the welding points, 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 saving space and facilitating the installation of the silencer assembly in an air conditioner.

[0026] Further, the silencer body 10 is made of stainless steel, the interface pipe 30 is made of copper, and the one-way valve 200 is made of copper. The stainless steel has good rigidity and low price, so that the use of the stainless steel for the silencer body 10 can greatly reduce the cost of the silencer assembly. The interface pipe 30 made of copper facilitates the direct connection of the silencer 100 with the one-way valve 200 made of copper.

[0027] The silencer body 10 comprises a body part 13, 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 that the noise generated by the flow of the refrigerant medium can be reduced.

[0028] The interface pipe 30 is connected to the outlet end 11, meaning the one-way valve 200 is connected to one side of the outlet end 11 of the muffler body 10. Thus, by setting the one-way valve 200, the refrigerant can only flow from the muffler 100 to the one-way valve 200, and not from the one-way valve 200 to the muffler 100. In this embodiment, the interface pipe 30 is sleeved on the outside of the outlet end 11 and welded to it. One end of the one-way valve 200 extends into the interface pipe 30 and is directly welded to it. Since the interface pipe 30 is sleeved on the outside of the outlet end 11, meaning the outlet end 11 extends into the interface pipe 30, the end face of the outlet end 11 forms a limiting surface. This limits the length of the one-way valve 200 extending into the interface pipe 30, greatly facilitating the assembly of the one-way valve 200 before welding. Furthermore, one end of the check valve 200 extending into the interface pipe 30 abuts against the end face of the outlet end 11, thus ensuring a secure connection between the silencer 100 and the check valve 200.

[0029] The outer wall of the outlet end 11 is provided with a first outer step 111, which is arranged along the circumference of the outlet end 11. The interface pipe 30 is sleeved on the first outer step 111. In this way, by setting the first outer step 111, the assembly position of the interface pipe 30 is restricted, which greatly facilitates the assembly of the interface pipe 30 and the muffler body 10 before welding.

[0030] In this embodiment, since the muffler body 10 is made of stainless steel, the interface pipe 30 is made of copper, and the one-way valve 200 is made of copper, the muffler body 10 and the interface pipe 30 are welded together by furnace brazing, and the interface pipe 30 and the one-way valve 200 are welded together by flame brazing. During the production and processing of the muffler assembly, the interface pipe 30 is first assembled onto one end of the muffler body 10, and then the muffler body 10 and the interface pipe 30 are furnace brazed to obtain the muffler 100. Afterwards, the interface pipe 30 of the muffler 100 is assembled together with one end of the one-way valve 200, and then the interface pipe 30 and the one-way valve 200 are flame brazed.

[0031] In one embodiment, please refer to Figure 2 The length of the outlet end 11 extending into the interface pipe 30 is A, the length of the one-way valve 200 extending into the interface pipe 30 is B, and the length of the interface pipe 30 is C, satisfying: 1 / 3C ≤ A ≤ 2 / 3C, and 1 / 3C ≤ B ≤ 2 / 3C. This ensures a certain overlap between the outlet end 11 and the interface pipe 30, and also ensures a certain overlap between the one-way valve 200 and the interface pipe 30, thereby guaranteeing a high connection strength between the outlet end 11 and the interface pipe 30, and consequently ensuring the structural strength of the silencer assembly.

[0032] Further, 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 In an 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 comprises 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 first, 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 first, 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 destroying 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.

[0034] 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 a second outer step 122, so that the assembly position of the first copper sleeve 60 is limited by the second outer step 122, greatly facilitating the assembly between 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.

[0035] When the first copper sleeve 60 and the second copper sleeve 70 are flame brazed, the position of the welding torch is deviated towards the first copper sleeve 60, so that heat can be transferred to the first stainless steel pipe 40 through the second copper sleeve 70, thereby avoiding overburning and damaging the weld between the muffler body 10 and the first copper sleeve 60.

[0036] The wall thickness of the first copper sleeve 60 is greater than that of the second copper sleeve 70, so that the structural strength of the connection between the muffler body 10 and the first stainless steel pipe 40 can be improved.

[0037] Referring to Figure 4 In an 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 and the first stainless steel pipe 40 is also made of stainless steel, the welding between the first stainless steel pipe 40 and the inlet end 12 is the welding between stainless steel and stainless steel, so that the first stainless steel pipe 40 and the inlet end 12 can be welded by furnace brazing. The first stainless steel pipe 40 is directly connected to the inlet end 12, and the welding method is simple and easy to process.

[0038] 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 at the inner step 121. The inner step 121 limits the length of the first stainless steel pipe 40 extending into the inlet end 12, so that the assembly of the first stainless steel pipe 40 before welding is greatly facilitated, which is conducive to simplifying the processing process.

[0039] Referring 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 one end of the one-way valve 200 away from the muffler 100. The second stainless steel pipe 50 is provided 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 furnace brazed, 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 one end of the one-way valve 200 away from the muffler 100 by flame brazing.

[0040] The application further provides an air conditioner comprising the silencer assembly of any one of the above embodiments. Since the silencer 100 is directly connected with the one-way valve 200, the connecting pipe in the prior art is cancelled, material can be saved, and thus the production cost can be greatly reduced. Moreover, 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 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 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, space can be saved, and thus the installation of the silencer assembly in the air conditioner is facilitated.

[0041] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but it should be considered that any combination of the technical features falls within the scope of the present disclosure as long as the combination does not result in contradictions.

[0042] Those skilled in the art should recognize that the above embodiments are used to illustrate the present application, but are not used as a limitation of the present application. Any appropriate changes and variations to the above embodiments, as long as they fall within the spirit and scope of the present application, are within the scope of the present application.
