具体实施方式
现有技术中，消音器和单向阀一般是分开设置的两个元器件。在生产空调器时，消音器通常通过一根独立的连接管连接单向阀。然而，由于消音器、单向阀通常为铜材质，连接管也为铜材质。如此，会导致空调器消耗大量铜材，而随着铜价的持续上涨，空调器成本也大大提升。
实施例1
请参阅图1至图3，本申请提供一种消音器组件300。消音器组件300包括消音器100以及单向阀200。消音器100包括消音器主体10以及设于消音器主体10一端的接口管30，接口管30直接连接单向阀200。如此，消音器100与单向阀200直接连接，相当于取消了现有技术中的连接管，如此可以节省材料，从而可大大降低生产成本。并且，现有技术中，由于消音器通过连接管连接单向阀，因此，消音器和单向阀之间存在两处焊点：一是消音器和 连接管之间的焊点，二是连接管和单向阀之间的焊点。而本申请中，由于消音器100和单向阀200直接连接，因此，消音器100和单向阀200之间只存在一处焊点。也就是说相对于现有技术而言，本申请的消音器组件300减少了焊点。由于焊点较多时，加工时需要进行多次焊接，工艺较为复杂，且生产效率低；并且焊接处容易发生泄露，存在多个焊点则发生泄漏的概率较高。本申请的消音器组件300由于减少了焊点，因此，既简化了加工工艺，提高了生产效率；又减少了焊接处泄漏的概率，提高了消音器100和单向阀200之间连接的可靠性。并且，由于省去了一个连接件，对于该消音器组件300而言，整体长度变短，有利于节省空间，从而便于该消音器组件300在空调器中的安装。
进一步地，消音器主体10为不锈钢材质，接口管30为铜材质，单向阀200为铜材质。不锈钢材质刚性好，且价格便宜，因此，消音器主体10采用不锈钢材质可大大降低该消音器组件300的成本。接口管30为铜材质便于消音器100和铜材质的单向阀200直接连接。
消音器主体10包括主体部13，主体部13的两端分别缩口形成进口端12和出口端11，如此，进口端12和出口端11的内径均小于主体部13的内径。冷媒介质从进口端12进入主体部13后，由于内径变大，冷媒介质的流速减小，也就是对冷媒介质起到缓冲作用，从而能够减小冷媒介质流动所产生的噪音。
接口管30连接于出口端11，也就是，单向阀200连接于消音器主体10出口端11的一侧，如此，通过设置单向阀200使得冷媒介质只能从消音器100流向单向阀200，而不能由单向阀200流向消音器100。本实施例中，接口管30套接于出口端11外侧并与出口端11相焊接，单向阀200的一端伸入接口 管30内并与接口管30直接焊接。接口管30套接于出口端11外侧，也就是出口端11伸入接口管30内，出口端11位于接口管30内的端面形成限位面112，该限位面112可以限制单向阀200伸入接口管30的长度，大大方便了焊接前单向阀200的装配。进一步地，单向阀200伸入接口管30的一端抵接于出口端11的限位面112，如此，消音器100与单向阀200之间连接牢固。
出口端11的外壁设有第一外台阶111，第一外台阶111沿着出口端11的周向设置，接口管30与第一外台阶111抵接。如此，通过设置第一外台阶111限制了接口管30的装配位置，大大方便了接口管30和消音器主体10焊接前的装配。
本实施例中，由于消音器主体10为不锈钢材质，接口管30为铜材质，单向阀200为铜材质。因此，消音器主体10与接口管30之间采用炉中钎焊的方式进行焊接，接口管30与单向阀200之间采用火焰钎焊的方式进行焊接。在生产加工消音器组件300时，先将接口管30装配在消音器主体10一端，然后消音器主体10和接口管30进行炉中钎焊得到消音器100。之后，再将消音器100的接口管30和单向阀200的一端装配在一起，然后接口管30和单向阀200进行火焰钎焊。
一实施例中，请参阅图2，出口端11伸入接口管30内的长度为A，单向阀200伸入接口管30内的部分的长度为B，接口管30的长度为C，A、B以及C满足以下关系式：1/3C≤A≤2/3C，且1/3C≤B≤2/3C。如此，保证了出口端11与接口管30之间具有一定的重合长度，且单向阀200与接口管30之间具有一定的重合长度，从而保证了出口端11与接口管30之间具有较高的连接强度，且单向阀200与接口管30之间具有较高的连接强度，进而保证了该消音器组件300的结构强度。
进一步地，该消音器组件300还包括第一不锈钢管40，第一不锈钢管40直接连接于进口端12，或者，第一不锈钢管40通过铜质连接件间接连接于进口端12。下面对第一不锈钢管40通过铜质连接件90间接连接于进口端12的情况进行详细说明。第一不锈钢管40直接连接于进口端12的情况将在实施例2中进行详细说明。
请参阅图3所示，一实施例中，第一不锈钢管40通过铜质连接件90间接连接于进口端12。具体地，铜质连接件90包括连接于进口端12的第一铜套60，以及连接于第一不锈钢管40的第二铜套70，第一铜套60与第二铜套70相焊接。如此，可以先分别将消音器主体10和第一铜套60焊接在一起，将第一不锈钢管40和第二铜套70焊接在一起，之后再将第一铜套60和第二铜套70焊接在一起，从而实现消音器主体10和第一不锈钢管40之间的连接。消音器主体10和第一铜套60之间采用炉中钎焊进行焊接，第一不锈钢管40和第二铜套70之间采用炉中钎焊进行焊接，第一铜套60和第二铜套70之间采用火焰钎焊进行焊接。由于设置有第一铜套60和第二铜套70，可以先对消音器主体10和第一铜套60进行炉中钎焊，并对第一不锈钢管40和第二铜套70进行炉中钎焊，则进入钎焊炉的管件长度较短，可以同时对多个管件进行炉中钎焊，操作更为方便，且有利于提高生产效率。并且，消音器主体10和第一不锈钢管40之间通过第一铜套60和第二铜套70连接，而第一铜套60和第二铜套70可以采用火焰钎焊进行焊接，当需要更换消音器主体10时，只需要破坏第一铜套60和第二铜套70之间的连接即可将消音器主体10从空调器中取下。之后再将新的消音器主体10焊接在第二铜套70上即可。因此，设置铜质连接件90使得空调器中更换消音器主体10非常方便。
进一步地，第一铜套60套接于进口端12外侧。具体地，进口端12的外 壁设有第二外台阶122，如此，通过设置第二外台阶122限制了第一铜套60的装配位置，大大方便了焊接前第一铜套60与消音器主体10进口端12之间的装配。第二铜套70套接于第一不锈钢管40一端的外侧，装配方便。第一铜套60套接于第二铜套70外侧，如此，大大方便了第一铜套60和第二铜套70之间进行火焰钎焊。
在对第一铜套60和第二铜套70进行火焰钎焊时，焊枪的位置偏向第一铜套60，如此，热量可通过第二铜套70传递给第一不锈钢管40，从而可避免出现过烧，避免对消音器主体10和第一铜套60之间的焊缝造成破坏。
第一铜套60的壁厚大于第二铜套70的壁厚，如此，可以提高消音器主体10和第一不锈钢管40的连接处的结构强度。容易想到的是，第二铜套70伸入第一铜套60的长度和进口端12伸入第二铜套70的长度可以参考图2中出口端11和单向阀200分别伸入接口管30长度的设计关系。
请参阅图1所示，进一步地，消音器组件300还包括第二不锈钢管50，第二不锈钢管50一端连接有第三铜套80，第三铜套80连接于单向阀200远离消音器100的一端。设置第二不锈钢管50方便了该消音器组件300在空调器中与其他管件进行连接。本实施例中，第三铜套80套设于第二不锈钢管50的外侧，且第三铜套80的一端伸入单向阀200内与单向阀200相焊接。在生产加工该消音器组件300时，先对第三铜套80和第二不锈钢管50进行炉中钎焊，将第三铜套80焊接于第二不锈钢管50一端，之后再通过火焰钎焊的方式将第三铜套80焊接于单向阀200远离消音器100的一端。
实施例2
请参阅图4至图6，本申请提供一种消音器组件300。消音器组件300包括消音器100以及单向阀200。消音器100包括消音器主体10以及设于消音 器主体10一端的接口管30，接口管30一端伸入消音器主体10内，另一端从消音器主体10端部伸出。接口管30伸出于消音器主体10的一端与单向阀200直接焊接。
由于接口管30与单向阀200直接焊接，也就是消音器100与单向阀200直接焊接，相当于取消了现有技术中的连接管，如此可以节省材料，从而可大大降低生产成本。并且，现有技术中，由于消音器通过连接管连接单向阀，因此，消音器和单向阀之间存在两处焊点：一是消音器和连接管之间的焊点，二是连接管和单向阀之间的焊点。而本申请中，由于消音器100和单向阀200直接连接，因此，消音器100和单向阀200之间只存在一处焊点。也就是说相对于现有技术而言，本申请的消音器组件300减少了焊点。由于焊点较多时，加工时需要进行多次焊接，工艺较为复杂，且生产效率低；并且焊接处容易发生泄露，存在多个焊点则发生泄漏的概率较高。本申请的消音器组件300由于减少了焊点，因此，既简化了加工工艺，提高了生产效率；又减少了焊接处泄漏的概率，提高了消音器100和单向阀200之间连接的可靠性。并且，由于省去了一个连接件，对于该消音器组件300而言，整体长度变短，有利于节省空间，从而便于该消音器组件300在空调器中的安装。
接口管30一端伸入消音器主体10内，增加了冷媒介质在消音器主体10内的流动路径，从而可对冷媒介质的流动起到缓冲作用，如此，有利于降低冷媒介质流动产生的噪音，使得消音器主体10具有更好的消音效果。
消音器主体10包括主体部13，主体部13的两端分别缩口形成进口端12和出口端11，如此，进口端12和出口端11的内径均小于主体部13的内径。冷媒介质从进口端12进入主体部13后，由于内径变大，冷媒介质的流速减小，也就是对冷媒介质起到缓冲作用，从而能够减小冷媒介质流动所产生的 噪音。
本申请中，接口管30连接于消音器主体10的出口端11。也就是，单向阀200连接于消音器主体10出口端11的一侧，如此，通过设置单向阀200使得冷媒介质只能从消音器100流向单向阀200，而不能由单向阀200流向消音器100。并且，虽然接口管30一端伸入消音器主体10内，但流进消音器主体10内的冷媒介质不会直接冲出出口端11，这是由于进口端1缩口形成对冷媒介质具有导流的作用，冷媒介质先向出口端11流动被消音器主体10内壁反弹后再流向接口管30伸入消音器主体10的一端，最后经过接口管30流出消音器100。如图4所示，图中带箭头的曲线为冷媒介质在消音器主体10内的流动路径示意图。如此，增加了冷媒介质在消音器主体10内的流动路径，从而可对冷媒介质的流动起到缓冲作用，如此，有利于降低冷媒介质流动产生的噪音，使得消音器100具有更好的消音效果。
进一步地，接口管30伸入消音器主体10内的部分的长度为E，消音器主体10的总长度为F，E和F满足以下关系式：E≥1/2F。接口管30伸入消音器主体10内的部分的长度越长，则冷媒介质在消音器主体10内的流动路径越长，则对冷媒介质的缓冲作用越强，从而消音效果越好。本实施中，E≥1/2F，使得冷媒介质在消音器主体10内的流动路径较长，从而使得消音器主体10具有较好的消音效果。
接口管30伸出于消音器主体10的一端形成扩口端31，单向阀200的一端插入扩口端31内。通过加工接口管30的一端而形成扩口端31，利用该扩口端31与单向阀200一端配合即可连接单向阀200和接口管30，不需要对单向阀200的端部进行加工。接口管30的一端进行扩口的工艺较为简单，容易加工，有利于提高该消音器组件300的生产效率。
进一步地，消音器主体10为不锈钢材质，接口管30为铜材质，单向阀200为铜材质。不锈钢材质刚性好，且价格便宜，因此，消音器主体10采用不锈钢材质可大大降低该消音器组件300的成本。接口管30为铜材质便于消音器100和铜材质的单向阀200直接连接。
消音器组件300还包括第一不锈钢管40，第一不锈钢管40直接连接于进口端12，或者，第一不锈钢管40通过铜质连接件90间接连接于进口端12(具体见上文)。下面对第一不锈钢管40直接连接于进口端12的情况进行详细说明。
请参阅图6所示，一实施例中，第一不锈钢管40直接连接于进口端12。由于消音器主体10为不锈钢材质，第一不锈钢管40也为不锈钢材质，因此第一不锈钢管40与进口端12之间的焊接为不锈钢材与不锈钢材之间的焊接，因此可采用炉中钎焊的方式焊接第一不锈钢管40和进口端12。第一不锈钢管40直接连接于进口端12，焊接方式简单，容易加工。
进一步地，进口端12内壁设有内台阶121，第一不锈钢管40伸入进口端12内，并焊接于内台阶121处。设置内台阶121限制了第一不锈钢管40伸入进口端12的长度，如此大大方便了焊接前第一不锈钢管40的装配，有利于简化加工过程。
请参阅图4所示，进一步地，消音器组件300还包括第二不锈钢管50，第二不锈钢管50一端连接有第三铜套80，第三铜套80连接于单向阀200远离消音器100的一端。设置第二不锈钢管50方便了该消音器组件300在空调器中与其他管件进行连接。本实施例中，第三铜套80套设于第二不锈钢管50的外侧，且第三铜套80的一端伸入单向阀200内与单向阀200相焊接。在生产加工该消音器组件300时，先对第三铜套80和第二不锈钢管50进行炉中 钎焊，将第三铜套80焊接于第二不锈钢管50一端，之后再通过火焰钎焊的方式将第三铜套80焊接于单向阀200远离消音器100的一端。
请参阅图7，本申请还提供一种空调器1000，包括以上任意一个实施例所述的消音器组件300。该空调器1000还包括压缩机400、冷凝器500、节流装置600以及蒸发器700，压缩机400、冷凝器500、节流装置600和蒸发器700通过管道依次连接，消音器组件300设置于冷凝器500和节流装置600之间的管道上。
该空调器1000由于消音器100与单向阀200之间直接连接，相当于取消了现有技术中的连接管，可以节省材料，从而可极大地降低生产成本。并且，由于消音器100和单向阀200直接连接，因此，消音器100和单向阀200之间只存在一处焊点。也就是说相对于现有技术而言，本申请的消音器组件300减少了焊点。如此，既简化了加工工艺，提高了生产效率；又减少了焊接处泄漏的概率，提高了消音器100和单向阀200之间连接的可靠性。并且，由于省去了一个连接件，对于该消音器组件300而言，整体长度变短，有利于节省空间，从而便于该消音器组件300在空调器1000中的安装。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
