関連出願
[001] 本出願は、２０１９年１２月２６日に出願された、出願番号が２０１９２２３８８５１８．８であり、発明の名称が「消音器及び空調」である中国特許出願の優先権を主張し、その全ての内容を引用することにより本出願に組み込まれる。 Related applications
[001] This application claims priority to a Chinese patent application filed on December 26, 2019, whose application number is 201922388518.8 and whose invention is titled "Muffler and Air Conditioner". The entire contents are incorporated into this application by reference.

[002] 本出願は空調機器の製造の技術分野に関し、特に、消音器及び空調に関する。 [002] The present application relates to the technical field of manufacturing air conditioning equipment, and particularly relates to silencers and air conditioning.

[003] 消音器はパイプラインの騒音低減装置として、通常、空調等の冷却機器に取り付けられ、騒音を緩和及び低減する作用を果たす。消音器は消音管を含み、消音管は中間部分が大きく両端が小さい構造であり、消音管の両端の開口は通常接続スリーブを介して接続管に接続され、この接続管は他の部材と連通する。消音効果を向上させるために、通常、消音管の両端の開口が比較的大きい縮径量（縮径量は大管径から小管径を引いてから大管径で割ったものであり、縮径量は消音管の変径量に対する説明である）を有する。しかしながら製造過程において、縮径量が大きすぎると、消音管の両端に割れ等の状況が発生しやすくなり、消音器の製造における合格率に多大な影響を及ぼす。 [003] Silencers are normally attached to cooling equipment such as air conditioners as noise reduction devices for pipelines, and function to alleviate and reduce noise. The silencer includes a silencer tube, and the silencer tube has a structure in which the middle part is large and both ends are small, and the openings at both ends of the silencer tube are usually connected to a connecting tube through a connecting sleeve, and this connecting tube communicates with other members. do. In order to improve the silencing effect, the openings at both ends of the muffling tube are usually reduced by a relatively large amount of diameter reduction (the amount of diameter reduction is calculated by subtracting the small pipe diameter from the large pipe diameter and then dividing it by the large pipe diameter. The diameter amount is an explanation for the amount of diameter change of the muffler pipe). However, in the manufacturing process, if the amount of diameter reduction is too large, conditions such as cracks are likely to occur at both ends of the muffler tube, which has a great impact on the acceptance rate in the muffler manufacturing process.

[004] 本出願の様々な実施例によれば、消音器を提供する。 [004] According to various embodiments of the present application, a silencer is provided.

[005] 消音器は、第１の管及びそれぞれ第１の管の両端と連通する２つの第２の管を含み、第２の管の管径が第１の管の管径より小さく、且つ第２の管の第１の管から離れた一端の外壁には段差が形成されており、段差は第２の管の周方向に沿って設けられ、且つ段差の外径が第２の管の外径より小さい消音管と、
第２の管の第１の管から離れた一端に設けられ、且つ第１の部分及び第２の部分を含み、第１の部分が段差に係合して固定され、且つ第２の部分の内径が第２の管の内径より小さい接続スリーブと、を含む。 [005] The muffler includes a first pipe and two second pipes each communicating with both ends of the first pipe, the pipe diameter of the second pipe being smaller than the pipe diameter of the first pipe, and A step is formed on the outer wall of one end of the second tube remote from the first tube, the step is provided along the circumferential direction of the second tube, and the outer diameter of the step is equal to that of the second tube. A muffling tube smaller than the outer diameter,
The second pipe is provided at one end of the second pipe remote from the first pipe, and includes a first part and a second part, the first part being engaged with and fixed to the step, and the second part being fixed. a connecting sleeve having an inner diameter smaller than the inner diameter of the second tube.

[006] 消音器を実際に取り付けて使用する場合、接続スリーブは消音管と空調における接続管とを連通するために使用され、消音効果を確保するために、接続管の管径は通常、消音管の管径より小さい。段差の外径が第２の管の外径より小さいため、接続スリーブの第２の部分の内径が変わらない場合、段差の配置は、第１の管に対する第２の管の縮径量及び／又は接続スリーブの第２の部分に対する第１の部分の拡径量を効果的に減少させ、消音管及び／又は接続スリーブの加工時に側壁の割れ等が発生する確率を大幅に低減させ、消音器の加工における製品の合格率を効果的に向上させた。 [006] When actually installing and using a silencer, the connection sleeve is used to communicate the silencer pipe and the connection pipe in air conditioning, and in order to ensure the noise reduction effect, the pipe diameter of the connection pipe is usually adjusted to Smaller than the pipe diameter. Since the outside diameter of the step is smaller than the outside diameter of the second tube, if the inside diameter of the second portion of the connecting sleeve does not change, the arrangement of the step will depend on the amount of diameter reduction of the second tube relative to the first tube and/or Alternatively, the amount of diameter expansion of the first part relative to the second part of the connecting sleeve can be effectively reduced, and the probability of side wall cracking etc. occurring during processing of the muffler pipe and/or the connecting sleeve can be greatly reduced, and the muffler effectively improved the acceptance rate of products in processing.

[007] 一実施例において、段差の第１の管に近接する一端の縁部には遷移面取りが形成されている。これにより、段差の加工過程におけるバリの発生を低減でき、次の接続スリーブとの取り付けが容易になる。 [007] In one embodiment, an edge of one end of the step proximate the first tube is formed with a transition chamfer. This can reduce the occurrence of burrs during the step machining process, and facilitates attachment to the next connecting sleeve.

[008] 一実施例において、遷移面取りの延伸方向と第２の管の端面との間の夾角が４５°より小さい。これにより、第２の管の段差が設けられている部分の管壁の厚さを増加させ、第２の管と接続スリーブとの接続強度を向上させることができる。 [008] In one embodiment, the included angle between the direction of extension of the transition chamfer and the end surface of the second tube is less than 45°. Thereby, the thickness of the tube wall of the portion of the second tube where the step is provided can be increased, and the connection strength between the second tube and the connection sleeve can be improved.

[009] 一実施例において、接続スリーブは、第１のソケット、遷移ソケット及び第２のソケットを含み、且つ遷移ソケットの両端はそれぞれ第１のソケット及び第２のソケットと連通し、第１のソケットが第１の部分であり、第２のソケットが第２の部分であり、且つ遷移ソケットの内径は第１の部分から第２の部分に向かう方向に沿って徐々に減少する。これにより、接続スリーブ１２０内の気流の流れ損失を低減できる。 [009] In one embodiment, the connection sleeve includes a first socket, a transition socket, and a second socket, and opposite ends of the transition socket communicate with the first socket and the second socket, respectively, and the ends of the transition socket communicate with the first socket and the second socket, respectively. The socket is the first part, the second socket is the second part, and the inner diameter of the transition socket gradually decreases along the direction from the first part to the second part. Thereby, the flow loss of the airflow within the connection sleeve 120 can be reduced.

[010] 一実施例において、第１のソケット、遷移ソケット及び第２のソケットは、一体に成形された構造である。これにより、溶接プロセスを省略することができる。 [010] In one example, the first socket, the transition socket, and the second socket are integrally molded structures. This allows the welding process to be omitted.

[011] 一実施例において、接続スリーブは銅スリーブである。これにより、接続スリーブと空調の接続管との溶接による接続が容易になる。 [011] In one embodiment, the connecting sleeve is a copper sleeve. This facilitates the welding connection between the connecting sleeve and the air conditioning connecting pipe.

[012] 一実施例において、第２の部分の内壁に制限カムが突出される。これにより、接続管を制限し、接続管が過度に挿入されて第２の管を損傷することを防止できる。 [012] In one embodiment, a limiting cam is protruded from the inner wall of the second portion. This restricts the connecting tube and prevents the connecting tube from being inserted excessively and damaging the second tube.

[013] 一実施例において、第２の部分の外側壁が内側に凹んで制限カムが形成される。これにより、プロセスが簡素化される。 [013] In one embodiment, the outer wall of the second portion is inwardly recessed to form a limiting cam. This simplifies the process.

[014] 一実施例において、制限カムは複数であり、複数の制限カムは接続スリーブの周方向に沿って間隔をおいて設けられる。これにより、制限効果を強化できる。 [014] In one embodiment, there is a plurality of restriction cams, and the plurality of restriction cams are provided at intervals along the circumferential direction of the connection sleeve. This allows the restriction effect to be strengthened.

[015] 一実施例において、第１の部分と第２の管とが固定して接続されるように、第１の部分の内壁と第２の管の軸方向の端面の間には溶接継手が形成されており、溶接継手は第２の管の周方向に沿って設けられる。 [015] In one embodiment, a welded joint is provided between the inner wall of the first portion and the axial end surface of the second tube such that the first portion and the second tube are fixedly connected. is formed, and the weld joint is provided along the circumferential direction of the second pipe.

[016] 一実施例において、溶接継手は銅錫溶接継手である。これにより、溶接強度を強化できる。 [016] In one embodiment, the weld joint is a copper-tin weld joint. Thereby, welding strength can be strengthened.

[017] 一実施例において、消音管はステンレス消音管である。これにより、消音管の使用寿命を延ばし、且つコストダウンできる。 [017] In one embodiment, the muffling tube is a stainless steel muffling tube. Thereby, the service life of the muffling pipe can be extended and costs can be reduced.

[018] 空調は、消音器と、それぞれ２つの第２の部分内に挿設されている２つの接続管と、を含む。 [018] The air conditioner includes a silencer and two connecting pipes each inserted into two second parts.

[032] 図１及び図２を参照すると、本出願は、空調（図示せず）及びその消音器１００を提供する。ここで空調は、消音器１００及び２つの接続管（図示せず）を含む。２つの接続管はそれぞれ消音器１００の両端と連通する。接続管の消音器１００から離れた一端は空調の他の部材と連通する。 [032] Referring to FIGS. 1 and 2, the present application provides an air conditioner (not shown) and a muffler 100 thereof. The air conditioner here includes a silencer 100 and two connecting pipes (not shown). The two connecting pipes communicate with both ends of the silencer 100, respectively. One end of the connecting pipe remote from the muffler 100 communicates with other members of the air conditioner.

[033] 説明すべきこととして、上記の消音器１００は、空調に使用されることに限られず、冷凍庫、冷蔵庫等の他の冷却機器に使用されてもよく、更に空気圧縮機、発電機、ボイラー排気口等の動力機器に使用されてもよい。本出願において、消音器１００の空調における適用を例として説明する。 [033] It should be explained that the above-described silencer 100 is not limited to being used for air conditioning, but may be used for other cooling equipment such as freezers and refrigerators, and may also be used for air compressors, generators, It may also be used in power equipment such as boiler exhaust ports. In this application, application of the silencer 100 in air conditioning will be described as an example.

[034] 本出願の好ましい実施例における消音器１００は、消音管１１０及び２つの接続スリーブ１２０を含む。 [034] The muffler 100 in the preferred embodiment of the present application includes a muffler tube 110 and two connecting sleeves 120.

[035] 図３を参照すると、消音管１１０は、第１の管１１１及びそれぞれ第１の管１１１の両端と連通する２つの第２の管１１２を含む。第２の管１１２の管径は第１の管１１１の管径より小さい。ここで管径とは、管外径と管内径の平均値を表す。第１の管１１１及び第２の管１１２は一体に成形された構造であってもよく、互いの間に溶接、接着等の形式により固定接続される接合構造であってもよく、本出願はこれに限定されない。 [035] Referring to FIG. 3, the muffling tube 110 includes a first tube 111 and two second tubes 112, each communicating with both ends of the first tube 111. The diameter of the second tube 112 is smaller than the diameter of the first tube 111. Here, the pipe diameter represents the average value of the pipe outer diameter and the pipe inner diameter. The first pipe 111 and the second pipe 112 may have an integrally molded structure, or may have a joint structure in which they are fixedly connected to each other by welding, adhesive, etc., and the present application It is not limited to this.

[036] 同時に図４を参照すると、第２の管１１２の第１の管１１１から離れた一端の外壁には第２の管１１２の周方向に沿って段差１１２１が形成されている。段差１１２１の外径は第２の管１１２の外径より小さい。具体的には、機械加工の方式（例えば、フライス加工、旋盤加工等の形態）により、第２の管１１２の第１の管１１１から離れた一端の外壁に対して加工を行って段差１１２１を形成する。 [036] Simultaneously referring to FIG. 4, a step 1121 is formed along the circumferential direction of the second tube 112 on the outer wall of one end of the second tube 112 remote from the first tube 111. The outer diameter of the step 1121 is smaller than the outer diameter of the second tube 112. Specifically, the step 1121 is formed by machining the outer wall of one end of the second pipe 112 away from the first pipe 111 using a machining method (for example, milling, lathe, etc.). Form.

[037] 本実施例において、段差１１２１の第１の管１１１に近接する一端の縁部には遷移面取り１１２２が形成されている。具体的には、遷移面取り１１２２の延伸方向と第２の管１１２の直径方向との間の夾角θは４５度より小さい、即ち、遷移面取り１１２２の延伸方向と第２の管１１２の端面との間の夾角θは４５度より小さい。遷移面取り１１２２の配置は、段差１１２１の加工過程におけるバリの発生を低減でき、次の消音器１００の組立が容易になり、消音器１００の加工品質を向上させ、且つ段差１１２１が設けられている第２の管１１２の管壁が過度に薄くならないように夾角θを４５度より小さくすることで、接続スリーブ１２０との溶接強度を向上させる。 [037] In this embodiment, a transition chamfer 1122 is formed on the edge of one end of the step 1121 close to the first tube 111. Specifically, the included angle θ between the extending direction of the transition chamfer 1122 and the diametrical direction of the second tube 112 is less than 45 degrees, that is, the included angle θ between the extending direction of the transition chamfer 1122 and the end surface of the second tube 112 is less than 45 degrees. The included angle θ between them is smaller than 45 degrees. The arrangement of the transition chamfer 1122 can reduce the occurrence of burrs during the process of processing the step 1121, facilitate the assembly of the next muffler 100, improve the processing quality of the muffler 100, and provide the step 1121. By making the included angle θ smaller than 45 degrees so that the wall of the second pipe 112 does not become excessively thin, the welding strength with the connecting sleeve 120 is improved.

[038] 本実施例において、第１の管１１１及び第２の管１１２は一体に成形された構造である。従って、消音管１１０は一体に成形された構造である。第１の管１１１及び第２の管１１２を一体に成形された構造とすることで、第１の管１１１と第２の管１１２との接続がより強固になるだけでなく、消音管１１０の加工もより簡単になる。 [038] In this embodiment, the first tube 111 and the second tube 112 are integrally molded. Therefore, the muffling pipe 110 has an integrally molded structure. By forming the first pipe 111 and the second pipe 112 into an integral structure, not only the connection between the first pipe 111 and the second pipe 112 becomes stronger, but also the connection between the first pipe 111 and the second pipe 112 becomes stronger. Processing is also easier.

[039] 本実施例において、消音管１１０はステンレス管である。ステンレスが比較的高い強度及び優れた耐腐食性を有するため、消音管１１０も比較的高い強度及び優れた耐腐食性能を有する。強度が比較的高いため、消音器１００が振動環境において長時間作動しても消音管１１０の割れ又は破裂等の状況が発生しにくく、耐腐食性能が優れるため、消音管１１０が長時間空気や他の水蒸気含有気体又は腐食性気体と接触しても錆びる確率が比較的低い。従って、消音管１１０をステンレス管とすることで、消音器１００の使用寿命を大きく延ばし、且つコストダウンできる。 [039] In this embodiment, the muffler tube 110 is a stainless steel tube. Since stainless steel has relatively high strength and excellent corrosion resistance, the muffler tube 110 also has relatively high strength and excellent corrosion resistance. Since the strength is relatively high, even if the silencer 100 is operated for a long time in a vibrating environment, conditions such as cracking or bursting of the silencer tube 110 are unlikely to occur.Since the corrosion resistance is excellent, the silencer tube 110 is not exposed to air for a long time. The probability of rusting even if it comes into contact with other water vapor-containing gases or corrosive gases is relatively low. Therefore, by using a stainless steel tube as the muffler tube 110, the service life of the muffler 100 can be greatly extended and the cost can be reduced.

[040] 同時に図５を参照すると、接続スリーブ１２０は、第２の管１１２の第１の管１１１から離れた一端に設けられる。従って、接続スリーブ１２０は２つであり、それぞれ２つの第２の管１１２に設けられている。接続スリーブ１２０は、第１の部分１２１及び第２の部分１２２を含む。第１の部分１２１は段差１１２１に係合して固定される。 [040] Referring simultaneously to FIG. 5, a connecting sleeve 120 is provided at one end of the second tube 112 remote from the first tube 111. There are therefore two connecting sleeves 120, one for each of the two second tubes 112. Connection sleeve 120 includes a first portion 121 and a second portion 122. The first portion 121 is engaged with and fixed to the step 1121.

[041] 接続スリーブ１２０はレジューサスリーブであり、第１の部分１２１は溶接、接着等の形式により第２の管１１２の外側に係合され、且つ第２の管１１２に固定して接続される。第２の部分１２２の内径は第２の管１１２の内径より小さい。従って、第２の部分１２２の内径が第１の部分１２１の内径より小さいため、接続スリーブ１２０はレジューサスリーブである。 [041] The connecting sleeve 120 is a reducer sleeve, and the first part 121 is engaged with the outside of the second pipe 112 by welding, gluing, etc., and is fixedly connected to the second pipe 112. . The inner diameter of the second portion 122 is smaller than the inner diameter of the second tube 112. Therefore, the connecting sleeve 120 is a reducer sleeve because the inner diameter of the second portion 122 is smaller than the inner diameter of the first portion 121.

[042] 空調において、接続管は第２の部分１２２内に挿設されている。従って、接続スリーブ１２０は、消音器１００と空調における他の部材とを接続するために使用される。接続スリーブ１２０の第２の部分１２２の内径が消音管１１０の第２の管１１２の内径より小さいため、接続スリーブ１２０は消音管１１０の両端にある第２の管１１２に対する更なる縮径を実現でき、消音器１００がより良好な消音効果を有するように確保する。 [042] In air conditioning, the connecting pipe is inserted into the second portion 122. Therefore, the connection sleeve 120 is used to connect the silencer 100 and other components in the air conditioning. Since the inner diameter of the second portion 122 of the connecting sleeve 120 is smaller than the inner diameter of the second tube 112 of the muffler tube 110, the connecting sleeve 120 provides further diameter reduction for the second tubes 112 at both ends of the muffler tube 110. and ensure that the muffler 100 has a better muffling effect.

[043] 本実施例において、接続スリーブ１２０は銅スリーブである。銅は、良好な延性、柔らかい性質等の特性を有するため、接続スリーブ１２０を銅スリーブとすることで、接続スリーブ１２０の加工が比較的簡単になるだけでなく、銅製の接続スリーブ１２０は同じパイプ材によって空調における接続管と溶接接続しやすくする。 [043] In this example, connection sleeve 120 is a copper sleeve. Copper has properties such as good ductility and softness, so using a copper sleeve as the connection sleeve 120 not only makes processing the connection sleeve 120 relatively easy, but also allows the connection sleeve 120 made of copper to be used with the same pipe. Depending on the material, it is easier to weld connections with connecting pipes in air conditioning.

[044] 段差１１２１の外径が第２の管１１２の外径より小さいため、接続スリーブ１２０の第２の部分１２２の内径が変わらない場合、段差１１２１の配置は、第１の管１１１に対する第２の管１１２の縮径量及び／又は接続スリーブ１２０の第２の部分１２２に対する第１の部分１２１の拡径量を効果的に減少させ、消音管１１０及び／又は接続スリーブ１２０の加工時に側壁の割れ等が発生する確率を大幅に低減させ、消音器１００の加工における製品合格率を効果的に向上させた。ここで、縮径量＝（第１の管１１１の管径－第２の管１１２の管径）／第１の管１１１の管径、拡径量＝（第１の部分１２１の内径－第２の部分１２２の内径）／第２の部分１２２の内径である。 [044] Since the outer diameter of the step 1121 is smaller than the outer diameter of the second tube 112, if the inner diameter of the second portion 122 of the connecting sleeve 120 does not change, the arrangement of the step 1121 is smaller than the outer diameter of the second tube 112. This effectively reduces the amount of diameter reduction of the second pipe 112 and/or the amount of diameter expansion of the first part 121 with respect to the second part 122 of the connection sleeve 120, and the side wall during machining of the silencer pipe 110 and/or the connection sleeve 120. The probability of occurrence of cracks, etc. is significantly reduced, and the product acceptance rate in processing the silencer 100 is effectively improved. Here, diameter reduction amount = (pipe diameter of first pipe 111 - pipe diameter of second pipe 112)/pipe diameter of first pipe 111, diameter expansion amount = (inner diameter of first portion 121 - second pipe diameter) (inner diameter of second portion 122)/inner diameter of second portion 122.

[045] 再度図５を参照すると、本実施例において、接続スリーブ１２０は、第１のソケット１２３、遷移ソケット１２４及び第２のソケット１２５を含む。遷移ソケット１２４の両端はそれぞれ第１のソケット１２３及び第２のソケット１２５と連通する。具体的には、第１のソケット１２３、遷移ソケット１２４及び第２のソケット１２５は同軸に設けられる。第１のソケット１２３は第１の部分１２１であり、第２のソケット１２５は第２の部分１２２である。従って第１のソケット１２３は段差１１２１に係合して固定される。遷移ソケット１２４の内径は第１の部分１２１から第２の部分１２２に向かう方向に沿って徐々に減少する。従って遷移ソケット１２４は円錐形筒である。これにより、遷移ソケット１２４の配置は、接続スリーブ１２０を流れる気流が接続スリーブ１２０内に衝突する確率を低減でき、消音器１００の消音効果を更に向上できる。 [045] Referring again to FIG. 5, in this example, connection sleeve 120 includes a first socket 123, a transition socket 124, and a second socket 125. Both ends of transition socket 124 communicate with first socket 123 and second socket 125, respectively. Specifically, the first socket 123, the transition socket 124, and the second socket 125 are coaxially provided. The first socket 123 is the first part 121 and the second socket 125 is the second part 122. Therefore, the first socket 123 is engaged with the step 1121 and fixed. The inner diameter of the transition socket 124 gradually decreases along the direction from the first section 121 to the second section 122. The transition socket 124 is therefore a conical tube. Accordingly, the arrangement of the transition socket 124 can reduce the probability that the airflow flowing through the connection sleeve 120 collides into the connection sleeve 120, and can further improve the sound reduction effect of the silencer 100.

[046] 更に、本実施例において、第１のソケット１２３、遷移ソケット１２４及び第２のソケット１２５は、一体に成形された構造である。第１のソケット１２３、遷移ソケット１２４及び第２のソケット１２５を一体に成形された構造とすると、第１のソケット１２３と遷移ソケット１２４及び遷移ソケット１２４と第２のソケット１２５との間の接続が強固になり、且つ接続スリーブ１２０の加工がより簡単になる。 [046] Furthermore, in this embodiment, the first socket 123, the transition socket 124, and the second socket 125 are integrally molded. When the first socket 123, the transition socket 124, and the second socket 125 are integrally molded, the connections between the first socket 123 and the transition socket 124 and between the transition socket 124 and the second socket 125 are It becomes stronger and the processing of the connection sleeve 120 becomes easier.

[047] 本実施例において、第２の部分１２２の第１の部分１２１に近接する内壁に制限カム１２２１が突出される。制限カム１２２１の配置は、第２の部分１２２内に挿設されている接続管に対して制限作用を果たすことができるため、制限カム１２２１の配置は接続管と消音器１００との取り付け時の取り付け精度を向上できる。また、制限カム１２２１の配置は、接続管が接続スリーブ１２０に挿入した深さが深すぎるため、接続管と消音器１００の第２の管１１２とが衝突して接続管が損傷してしまう等の状況が発生する確率も低減でき、消音器１００と他の部材の取り付けが順調となることを確保する。 [047] In this embodiment, a limiting cam 1221 is protruded from the inner wall of the second portion 122 adjacent to the first portion 121. The arrangement of the restriction cam 1221 can perform a restriction action on the connecting pipe inserted into the second portion 122, so the arrangement of the restricting cam 1221 is determined when the connecting pipe and the silencer 100 are attached. Installation accuracy can be improved. In addition, since the arrangement of the restriction cam 1221 is such that the depth at which the connecting pipe is inserted into the connecting sleeve 120 is too deep, the connecting pipe collides with the second pipe 112 of the silencer 100, resulting in damage to the connecting pipe. The probability of the situation occurring can be reduced, and the installation of the silencer 100 and other members can be ensured smoothly.

[048] 接続スリーブ１２０が第１のソケット１２３、遷移ソケット１２４及び第２のソケット１２５を含む場合、制限カム１２２１が第２のソケット１２５の内壁に突出される。 [048] When the connection sleeve 120 includes a first socket 123, a transition socket 124 and a second socket 125, a limiting cam 1221 is projected on the inner wall of the second socket 125.

[049] 更に、本実施例において、第２の部分１２２の側壁が内側に凹んで制限カム１２２１が形成される。接続スリーブ１２０の加工過程において、プレス機械を使用して第２の部分１２２の側壁に対してプレスを行うと制限カム１２２１の加工が実現できる。従って、制限カム１２２１を第２の部分１２２の側壁が内側に凹んで形成されるように設定することで制限カム１２２１の加工が大きく簡素化され、第２の部分１２２の側壁が内側に凹む場合、これに応じて第２の部分１２２の外表面には溝が形成される。 [049] Furthermore, in this embodiment, the side wall of the second portion 122 is recessed inward to form a limiting cam 1221. In the process of manufacturing the connecting sleeve 120, the limiting cam 1221 can be formed by pressing the side wall of the second portion 122 using a press machine. Therefore, by setting the limiting cam 1221 so that the side wall of the second portion 122 is recessed inward, the machining of the limiting cam 1221 is greatly simplified. , grooves are formed on the outer surface of the second portion 122 accordingly.

[050] 更に、本実施例において、制限カム１２２１は複数であり、且つ複数の制限カム１２２１は接続スリーブ１２０の周方向に沿って間隔をおいて設けられる。これにより、複数の制限カム１２２１の配置は、接続管に対する制限効果を向上させ、接続管と消音管１１０の第２の管１１２の内壁とが衝突する確率を更に低減させることができる。 [050] Further, in this embodiment, there are a plurality of restriction cams 1221, and the plurality of restriction cams 1221 are provided at intervals along the circumferential direction of the connection sleeve 120. Accordingly, the arrangement of the plurality of restriction cams 1221 can improve the restriction effect on the connecting pipe and further reduce the probability that the connecting pipe and the inner wall of the second pipe 112 of the muffler pipe 110 will collide.

[051] 再度図１及び図２を参照すると、本実施例において第１の部分１２１と第２の管１１２とが固定して接続されるように、第１の部分１２１の内壁と第２の管１１２の軸方向の端面の間には溶接継手１３０が形成されている。溶接継手１３０は、第２の管１１２の周方向に沿って設けられる。ここで、溶接継手１３０は、溶融後半田材が冷却した後に硬化して形成された接続継手であり、接続スリーブ１２０と消音管１１０との溶接に使用される。溶接継手１３０が第２の管１１２の周方向に沿って設けられているため、第２の管１１２と接続スリーブ１２０との間の封止性を向上できる。従って、溶接継手１３０の配置は、接続スリーブ１２０と消音管１１０との間の接続が比較的強固になり、且つ消音器１００の封止性能も向上させた。 [051] Referring again to FIGS. 1 and 2, in this embodiment, the inner wall of the first portion 121 and the second tube 112 are connected to each other in a fixed manner. A weld joint 130 is formed between the axial end faces of the tube 112. Weld joint 130 is provided along the circumferential direction of second pipe 112. Here, the weld joint 130 is a connection joint formed by hardening the molten solder material after cooling, and is used for welding the connection sleeve 120 and the muffler pipe 110. Since the weld joint 130 is provided along the circumferential direction of the second pipe 112, the sealing performance between the second pipe 112 and the connection sleeve 120 can be improved. Therefore, the arrangement of the welded joint 130 makes the connection between the connecting sleeve 120 and the muffler tube 110 relatively strong, and also improves the sealing performance of the muffler 100.

[052] 再度図６及び図７を参照すると、具体的には、溶接前に溶接継手１３０を形成する半田材は溶接リング１４０である。溶接リング１４０は、第１の部分１２１内に収容され、且つ第１の部分１２１の内壁と第２の管１１２の第１の管１１１から離れた一端の端部との間に当接する。溶接リング１４０は溶接材であり、その溶融温度は比較的低い。接続スリーブ１２０と消音管１１０とを溶接する必要がある場合、溶接リング１４０が収容されている接続スリーブ１２０を第２の管１１２の段差１１２１に係合し、共にろう接機器に配置して加熱した後に冷却するだけで接続スリーブ１２０と消音管１１０との間の溶接を完了できる。従って、溶接リング１４０の配置は、接続スリーブ１２０と消音管１１０との間の溶接作業をより容易にすると共に、接続スリーブ１２０と消音管１１０との間の溶接信頼性を更に向上させる。溶接リング１４０の材質は、通常、銅錫合金、銀銅合金、錫鉛合金等である。 [052] Referring again to FIGS. 6 and 7, specifically, the solder material that forms the weld joint 130 before welding is the weld ring 140. The welding ring 140 is housed within the first section 121 and abuts between the inner wall of the first section 121 and the end of the second tube 112 at one end remote from the first tube 111 . Welding ring 140 is a welding material whose melting temperature is relatively low. If it is necessary to weld the connecting sleeve 120 and the muffling tube 110, the connecting sleeve 120, in which the welding ring 140 is housed, is engaged with the step 1121 of the second tube 112, and both are placed in the soldering equipment and heated. Welding between the connecting sleeve 120 and the muffling tube 110 can be completed by simply cooling the welding tube 110 after the welding. Therefore, the arrangement of the welding ring 140 makes the welding operation between the connecting sleeve 120 and the muffler tube 110 easier, and further improves the welding reliability between the connecting sleeve 120 and the muffler tube 110. The material of the welding ring 140 is usually a copper-tin alloy, a silver-copper alloy, a tin-lead alloy, or the like.

[053] 更に、本実施例において、銅錫合金が低融点、高強度等の特性を有するため、溶接継手１３０は全て低融点、高強度等の利点を有する。従って、溶接継手１３０を銅錫溶接継手とすることで、接続スリーブ１２０と消音管１１０との間の溶接強度が比較的高くなり、更に接続スリーブ１２０と消音管１１０との間の接続がより強固になる。 Furthermore, in this embodiment, since the copper-tin alloy has characteristics such as a low melting point and high strength, all welded joints 130 have advantages such as a low melting point and high strength. Therefore, by using the welded joint 130 as a copper-tin welded joint, the welding strength between the connection sleeve 120 and the muffler pipe 110 is relatively high, and the connection between the connection sleeve 120 and the muffler pipe 110 is further strengthened. become.

[054] 上記の空調及びその消音器１００は、実際の使用と取り付けの際、接続スリーブ１２０は消音管１１０と空調における接続管とを連通するために使用され、消音効果を確保するために、接続管の管径はいずれも比較的小さい。段差１１２１の外径が第２の管１１２の外径より小さいため、接続スリーブ１２０の第２の部分１２２の内径が変更しない場合、段差１１２１の配置は、第１の管１１１に対する第２の管１１２の縮径量及び／又は接続スリーブ１２０の第２の部分１２２に対する第１の部分１２１の拡径量を効果的に減少させ、消音管１１０及び／又は接続スリーブ１２０の加工時に側壁の割れ等が発生する可能性を大幅に低減し、消音器１００の加工における製品合格率を効果的に向上させた。 [054] During actual use and installation of the above air conditioner and its muffler 100, the connection sleeve 120 is used to communicate the muffler pipe 110 and the connecting pipe in the air conditioner, and in order to ensure the sound muffling effect, The diameters of the connecting pipes are all relatively small. Since the outer diameter of the step 1121 is smaller than the outer diameter of the second tube 112, the arrangement of the step 1121 is similar to that of the second tube with respect to the first tube 111 if the inner diameter of the second portion 122 of the connecting sleeve 120 does not change. 112 and/or the amount of diameter expansion of the first part 121 relative to the second part 122 of the connecting sleeve 120, thereby preventing side wall cracks, etc. during processing of the muffler pipe 110 and/or the connecting sleeve 120. This greatly reduces the possibility of this occurring, and effectively improves the product acceptance rate in the processing of the silencer 100.
