具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图27描述根据本申请实施例的衣物处理装置。这里的衣物处理装置可以是滚筒洗衣机、波轮洗衣机、洗干一体机，衣物处理装置也可以是其他类型的装置，这里不作限制。
如图1-图11所示，根据本申请实施例的衣物处理装置包括盛水桶(未示出)、洗涤剂盒300和微气泡发生器100。盛水桶为用于处理衣物的桶体，例如盛水桶可以是滚筒洗衣机的内筒，也可以是波轮洗衣机的盛水桶等。洗涤剂盒300内限定有洗涤剂腔，用于盛放洗涤剂，洗涤剂盒300具有洗涤进口和洗涤出口，洗涤进口可以与衣物处理装置的总进水管200相连，洗涤出口可以与盛水桶相连，从而将洗涤剂投放到盛水桶中。
进一步地，微气泡发生器100用于制造微气泡水，制得的微气泡水可以用来参与衣物的洗涤过程，也可以用来参与衣物的漂洗过程，还可以参与到衣物处理装置其他需要用到微气泡水的过程中，例如清洗密封圈、清污等。具体地，微气泡发生器100安装于洗涤剂盒300，微气泡发生器100的入水口101与衣物处理装置的总进水管200相连，微气泡发生器100的出水口102与洗涤剂盒300或者盛水桶相连。
根据本申请实施例的衣物处理装置，通过采用微气泡发生器100，并将微气泡发生器100安装在洗涤剂盒300，从而方便将制得的微气泡水导向洗涤剂盒300或者盛水桶内，不仅利于提高结构紧凑性、集成度以及稳定性，而且可以降低洗涤剂的用量，节约水电资源，减少衣物上残留的洗涤剂。并且，上述微气泡发生器100，无需安装多个阀门，成本低、微泡制造效果好。
根据本申请的一个实施例，如图1和图2所示，衣物处理装置的总进水管200上设有进水阀210，总进水管200上设有多个分支，进水阀210用于控制各分支的进水状态。
具体地，如图2所示，总进水管200上连出第一支管211、第二支管212、第三支管213，第一支管211与入水管14相连，第二支管212、第三支管213均与洗涤剂盒300相连，第二支管212和第三支管213分别用于主洗进水和预洗进水。
根据本申请一个可选的实施例，微气泡发生器100的出水口102通过独立于洗涤剂盒300的微气泡接管与盛水桶相连，即该微气泡接管与洗涤剂盒300无任何连接关系，微气泡接管的一端与微气泡发生器102的出水口102相连，微气泡接管的另一端与盛水桶相连，从而将微气泡发生器100制得的微气泡水直接通入盛水桶中，使其参与到盛水桶内的洗涤剂的溶解，提高衣物的洗净比。
在一些实施例中，如图3所示，洗涤剂盒300具有进水汇管51，进水汇管51与洗涤出口连通，进水汇管51在水流的流动方向上位于洗涤出口的下游，进水汇管51与盛水桶相连。
进一步地，微气泡发生器100的出水口102与进水汇管51相连，从而使得微气泡发 生器100的出水口102与盛水桶通过进水汇管51相连。从洗涤出口排出的洗涤剂和水的混合物以及微气泡发生器100制得的微气泡水均可以从进水汇管51排出洗涤剂盒300外，并通入盛水桶中。可选地，进水汇管51形成在洗涤剂盒300的底部，从而保证洗涤剂盒300内的残水可以排尽。
根据本申请另一个可选的实施例，洗涤进口包括如图6示出的第一洗涤进口311和如图2示出的第二洗涤进口313。
微气泡发生器100的出水口102可以与第一洗涤进口311相连，从而将微气泡发生器100制得的微气泡水通入洗涤剂盒300内，利用微气泡的爆破能量加快洗涤剂分化成更小份，促进洗涤剂的充分且快速溶解，而总进水管200可以与第二洗涤进口313相连，从而将原水直接通入洗涤剂盒300内。
由此，利用第一洗涤进口311可以向洗涤剂盒300内通入微气泡水，利用第二洗涤进口313可以向洗涤剂盒300内通入原水，保证足够的进水量，尤其在微气泡发生器100因溶气而迟缓时，或者在不需要微气泡水的情况下，通过第二洗涤进口313进水，由此可以根据实际情况选择性地将微气泡水或者原水通入洗涤剂盒300内，从而参与到洗涤剂的溶解。
其中，如图6所示，第一洗涤进口311位于微气泡发生器100的出水口102的上方，出水口102可以通过第一微气泡接管521连接第一洗涤进口311，这样便于微气泡发生器100与洗涤剂盒300并排设置。第一微气泡接管521呈S形设置，这样设计有利于将管道拉长，使微气泡水从出水口102流出到流入洗涤剂腔内，有足够的消化时间，从而使微气泡发生器100可以充分制出足够数量、足够尺寸的微气泡。
如图1-图11所示，根据本申请另一个实施例的衣物处理装置，微气泡发生器100具有溶气腔10、与溶气腔10连通的入口11、出口12和辅助口18，辅助口18处设有控制阀4，控制阀4用于控制辅助口18的通断。
其中，溶气腔10的入口11形成微气泡发生器100的入水口101，或者溶气腔10的入口11与微气泡发生器100的入水口101，溶气腔10的出口12与微气泡发生器100的出水口102连通。
根据本申请实施例的衣物处理装置，通过在微气泡发生器100的辅助口18处设置控制阀4，从而控制辅助口18的通断，并结合溶气腔10的出口12，不仅可以保证微气泡发生器100的溶气腔10内的残水可以排尽，而且可以向溶气腔10内补足空气，使溶气腔10内快速恢复常压，保证微气泡发生器100在下次使用时可以溶解足够的空气。
如图1-图5所示，在本申请一个可选的实施例，辅助口18位于出口12的上方，即辅助口18的位置高于出口12的位置，辅助口18可以用于进气。
举例而言，微气泡发生器100包括溶气罐1，入口11位于溶气罐1的最顶部或者靠近最顶部，出口12位于溶气罐1的最底部或者靠近最底部，辅助口18位于溶气罐1的最顶部或者靠近最顶部。
微气泡发生器100工作时，控制阀4关闭，向微气泡发生器100内通水，水流流经 入水口101、入口11进入溶气腔10内，经过微气泡发生器100处理后，制得的微气泡水从出水口102排出；每次使用完微气泡发生器100后，停止向入水口101通水，并打开控制阀4，外界空气从辅助口18进入溶气腔10内，使溶气腔10内快速恢复常压，保证微气泡发生器100在下次使用时可以溶解足够的空气，而溶气腔10内的残水在气压差以及自身重力的作用下，流经出口12、出水口102，最终完全排出。
在一些实施例中，出口12至少通过第二微气泡接管522与进水汇管51相连，从而使得出口12与盛水桶通过第二微气泡接管522以及进水汇管51相连。举例而言，如图3所示，微气泡发生器100的出水口102通过第二微气泡接管522与进水汇管51相连，微气泡发生器100制得的微气泡水通过第二微气泡接管522以及进水汇管51通入盛水桶中，参与到盛水桶中洗涤剂的溶解等，提升衣物的洗净比。
在一些实施例中，如图4和图5所示，洗涤剂盒300内限定出回气通道301，回气通道301与辅助口18相连。从图2和图5中可以看出，洗涤剂盒300在微气泡发生器100的设有控制阀4处相配合，该处为溶气罐1的辅助口18与洗涤剂盒300上回气通道301的通道口相连。
回气通道301的设置，可以方便辅助口18打开后，有足够空气充入溶气腔10。可想而知的是，微气泡发生器100和洗涤剂盒300是封装在衣物处理装置的外壳内的，外壳内布置了各种部件，各部件的密集设置可能会使辅助口18堵住，或者充气不畅。而回气通道301的设置，相当于在洗涤剂盒300内预存上空气，一旦辅助口18打开则能立即供应空气，可避免因安装空间的限制或者安装的密封要求等原因导致供气量不足的问题。
而且回气通道301的设置，还可以避免辅助口18打开瞬间，因溶气罐1内气压过高导致向外喷溅的情况。另外假如出现喷溅的情况，回气通道301也是一种导流通道，可以将喷出的水导回溶气罐1，或者导向其他部件排出，例如导向洗涤剂腔或者总排水管等。
这里要说明的是，回气通道301也可以设置在微气泡发生器100上，例如回气通道301可以形成在溶气罐1上。这里将回气通道301设置在洗涤剂盒300内，一方面洗涤剂盒300内空间大、回路多，不需要占用微气泡发生器100内空间(因为空气溶解需要一定空间)，还能充分利用洗涤剂盒300内闲置的空间(洗涤剂盒300内流路多，闲置空间大)，另一方面可以拉长回气通道301的长度，对于补气、防水被喷出都有缓冲作用。有的衣物处理装置的洗涤剂盒300上设有与衣物处理装置外部连接的气孔，此时利用该气孔补气，防止空气供应不足的情况。当然，当回气通道301设置在溶气罐1上时，回气通道301也可直接与衣物处理装置上的气孔相连。
有的示例中，回气通道301与洗涤剂腔隔绝开，这样设置可避免溶气罐1和洗涤剂盒300内部水路乱流的情况。
可选地，如图5所示，回气通道301位于溶气腔10的上方，这样设置，是为了当辅助口18处喷出水花后，回气通道301能将喷出的水收集后回流到溶气罐1中。
如图6至图11所示，在本申请另一个可选的实施例，辅助口18位于出口12的下方，即辅助口18的位置低于出口12的位置，甚至辅助口18位于溶气罐1的最低处，辅助口18可以用于排水。
微气泡发生器100工作时，控制阀4关闭，向微气泡发生器100内通水，水流流经入水口101、入口11进入溶气腔10内，经过微气泡发生器100处理后，制得的微气泡水从出水口102排出，以通入洗涤剂盒300或者盛水桶；每次使用完微气泡发生器100后，停止向入水口101通水，并打开控制阀4，在水位下降到露出出口12的位置时，外界空气可以从常开状态的出口12进入溶气腔10中，使溶气腔10内快速恢复常压，保证微气泡发生器100在下次使用时可以溶解足够的空气，而由于辅助口18处于导通状态，并且辅助口18的位置低于出口12的位置，溶气腔10内的残水受气压差以及残水自身重力的作用，从辅助口18排出，最终将溶气腔10内的残水排尽。
在进一步的实施例中，出口12至少通过第一微气泡接管521与洗涤进口相连。具体地，如图6所示，出水口102通过第一微气泡接管521与洗涤进口相连，从而将微气泡发生器100制得的微气泡水通入洗涤剂盒300内，参与到洗涤盒内洗涤剂的溶解。
举例而言，辅助口18可以与盛水桶相连，从而将溶气腔10内的残水排到盛水桶中，并且盛水桶中的空气也可以通过辅助口18进入溶气腔10内。再如，辅助口18也可以与衣物处理装置的总排水管相连，从而将溶气腔10内的残水通过总排水管排出外界。由于总排水管位于衣物处理装置的底部，而盛水桶容积大、底壁位置低，将辅助口18连接盛水桶或总排水管，水位高度差大、排水更快。
如图7以及图9-图10所示，在本实施例中，第一洗涤进口311与微气泡发生器100的出水口102第一微气泡接管521相连，第二洗涤进口313适于与总进水管200连接，用于预洗进水，辅助口18与洗涤剂盒300底部的进水汇管51相连，从而使辅助口18与盛水桶通过进水汇管51相连，从辅助口18排出的残水可以从进水汇管51排出洗涤剂盒300外，最终通入盛水桶中。
如图1以及图12至图16所示，根据本申请又一个实施例的衣物处理装置，微气泡发生器100可拆卸地安装于洗涤剂盒300的后方，且微气泡发生器100与洗涤剂盒300或者盛水桶相连。
根据本申请实施例的衣物处理装置，通过将微气泡发生器100可拆卸地安装在洗涤剂盒300的后方，使微气泡发生器100的设置不影响洗涤剂盒300的使用，并且可以方便将制得的微气泡水导向洗涤剂盒300或者盛水桶内，不仅利于提高结构紧凑性、集成度以及稳定性，而且可以降低洗涤剂的用量，节约水电资源，减少衣物上残留的洗涤剂。
为了将微气泡发生器100与洗涤剂盒300良好整合，可以将微气泡发生器100与洗涤剂盒300的顶部大体平齐设置，将微气泡发生器100与洗涤剂盒300的底部大体平齐设置。
如图1所示，根据本申请的一个实施例，微气泡发生器100的溶气罐1上还设置有安装耳192，安装耳192用于连接衣物处理装置的机体，这样可进一步提高集成化部件 的安装可靠性。
在一些实施例中，如图1所示，微气泡发生器100的溶气罐1上设有多个固定耳191，每个固定耳191与洗涤剂盒300相连。例如，每个固定耳191通过穿设于连接孔的紧固件与洗涤剂盒300实现连接。这种设置方式，可以保证微气泡发生器100与洗涤剂盒300一体化连接的可靠性。一体化连接后，抗震性能会得到明显加强。另外，微气泡发生器100和洗涤剂盒300均是过水部件，将二者结合在一体整合体积，有利于提高整体结构的稳定性。
在一些实施例中，每个固定耳191设有连接孔，多个连接孔中的至少一部分的中心线相互垂直设置，从而从多个方向对微气泡发生器100进行固定，保证微气泡发生器100与洗涤剂盒300的连接可靠性。
在一些实施例中，如图1所示，至少一个固定耳191为第一固定耳1911，第一固定耳1911沿前后方向延伸，即第一固定耳1911朝洗涤剂盒300一侧延伸，其中，第一固定耳1911的前端设有第一连接孔1915，第一固定耳1911通过穿设于第一连接孔1915的第一紧固件与洗涤剂盒300相连。
在一些示例中，如图1所示，至少一个固定耳191为第二固定耳1912，第二固定耳1912沿前后方向延伸，其中，第二固定耳1912的前端设有第二连接孔1916，第二固定耳1912通过穿设于第二连接孔1916的第二紧固件与洗涤剂盒300相连。
在一些具体示例中，第一连接孔1915的中心线的延伸方向与第二连接孔1916的中心线的延伸方向不同。在本实施例中，第一连接孔1915的中心线沿上下方向延伸，第二连接孔1916的中心线沿左右方向延伸，由此通过两个紧固件从上下方向和左右方向对微气泡发生器100进行固定，进一步保证微气泡发生器100与洗涤剂盒300的连接可靠性。
在进一步的实施例中，如图1所示，至少一个固定耳191为第三固定耳1913，第三固定耳1913具有沿洗涤剂盒300的宽度方向(如图1所示的左右方向)延伸的连接部1914，其中，连接部1914上设有中心线沿前后方向延伸的第三连接孔1917，第三固定耳1913通过穿设于第三连接孔1917的第三紧固件与洗涤剂盒300相连。由此通过三个紧固件从上下方向、左右方向和前后方向对微气泡发生器100进行固定，进一步保证微气泡发生器100与洗涤剂盒300的连接可靠性。
如图12至图16所示，根据本申请的一个实施例，微气泡发生器100具有溶气腔10、与溶气腔10连通的入口11、出口12和辅助口18，辅助口18处设有控制阀4，用于控制辅助口18的通断，出口12或者辅助口18至少通过排水管53与盛水桶连接。
例如，溶气腔10的出口12可以通过排水管53与盛水桶连接，从而将制得的微气泡水排到盛水桶中；再如，辅助口18可以通过排水管53与盛水桶连接，从而有利于将微气泡发生器100内残水排尽。
在一些实施例中，如图13所示，排水管53的一端与进水汇管51相连，排水管53的另一端与出口12或者辅助口18相连。可选地，排水管53为软管。
在一些示例中，进水汇管51的侧周壁设有朝外凸出设置的连接接头511，排水管53的一端套设于连接接头511，排水管53通过可调节的箍圈或者扎带与连接接头511相连，排水管53的另一端也可以通过可调节的箍圈或者扎带与微气泡发生器100相连，连接方便、可靠。
在一些可选的实施例中，辅助口18设于出口12的下方，辅助口18通过排水管53与盛水桶相连，不仅利于将溶气腔10内的残水排尽，还可以使外界空气通过出口12进入溶气腔10中，使溶气腔10快速恢复常压，方便微气泡发生器100下一次使用。
在另一些可选的实施例中，辅助口18设于出口12的上方，出口12通过排水管53与盛水桶相连，从而将微气泡发生器100制得的微气泡水通过排水管53通入盛水桶中，参与到盛水桶中洗涤剂的溶解等。
在一些实施例中，如图14和图15所示，洗涤剂盒300的底部设有卡槽3141，排水管53适于从卡槽3141的一侧开口滑入卡槽3141内，从而将排水管53固定在洗涤剂盒300的底部，避免排水管53发生较大幅度的晃动而影响连接效果，进而保证排水管53的使用可靠性。
在一些示例中，如图15所示，卡槽3141的开口处设有导向面3142，导向面3142从卡槽3141外向卡槽3141内逐渐向开口的中心延伸，从而方便将排水管53从开口处滑入卡槽3141内，安装方便。
在图15示出的实施例中，洗涤剂盒300的底部设有卡钩314，卡钩314限定出卡槽3141，其中，卡钩314的背向卡槽3141的一侧设有加强凸筋3143，加强凸筋3143的一端延伸至洗涤剂盒300的底部，通过在卡钩314的背向卡槽3141的一侧设置加强凸筋3143，可以保证卡钩314的结构强度，从而保证排水管53的安装可靠性。
下面针对微气泡发生器100的具体结构以及工作原理进行详细描述。
如图17和图18所示，微气泡发生器100包括溶气罐1和空化件2。溶气罐1内限定出溶气腔10，溶气罐1具有出入水流的入口11和出口12。
溶气罐1的入口11形成微气泡发生器100的入水口101，或者溶气罐1的入口11与入水口101连通，入口11与水源(例如衣物处理装置的总进水管200)相连。微气泡发生器100的出水口102形成在空化件2上，空化件2设在溶气罐1外并与出口12相连，或者空化件2设在出口12处，空化件2通过空化效应将溶于水中的气体制成微气泡。
在一些实施例中，溶气罐1还具有与溶气腔10连通的辅助口18，辅助口18在导通状态和断开状态之间切换，在辅助口18切换至导通状态的条件下，辅助口18与溶气腔10连通。进一步地，微气泡发生器100还包括控制阀4，控制阀4设在辅助口18处，用于控制辅助口18的通断。
微气泡发生器100使用时，控制阀4关闭辅助口18，由入口11进水溶气，从而形成含高浓度空气溶质的水，含高浓度空气溶质的水进入空化件2，空化件2利用空化效应制成微气泡，从空化件2排出的水流中含有大量微气泡，即制得微气泡水，微气泡发 生器100使用完毕，控制阀4打开辅助口18。
制得的微气泡水可以用于洗涤等多方面用途。如果水中带有洗衣粉、洗衣液等洗涤剂，微气泡的爆破能量可以加快洗涤剂分化成更小份，从而促进洗涤剂的充分且快速溶解。因此可以将微气泡发生器100产生的微气泡水通入洗涤剂盒300内以参与洗涤剂溶解，也可以通入盛水桶中参与洗涤剂溶解，还可以通入衣物处理装置的其他部位参与洗涤剂的充分溶解。如果衣物上的污渍比较顽固，仅仅靠洗涤剂溶解或者靠衣物之间的摩擦，污渍也很难除尽。微气泡发生器100产生的微气泡水，可以参与衣物的洗涤，通过微气泡的爆破能量来增强衣物脏污的去除能力。同样的，当微气泡水参与漂洗过程，微气泡的爆破能量可以使衣物上沾染的洗涤剂尽快溶解于水中，避免衣物残留。此外，微气泡水的增强能力，有助于节省衣物处理装置的用水量。
如图18所示，在本申请实施例中，溶气罐1的入口11位于出口12的上方，入口11与出口12在水平方向上相错开。而且微气泡发生器100在溶气时构造成出水流速小于入水流速，即单位时间内出水少、入水多。水流由入口11注入溶气罐1，由于入水流速大于出水流速，因此在往溶气罐1注入一段时间水后溶气腔10内的水位逐渐上升，溶气腔10的水位上升后会很快没过出口12，使出口12处形成水封，溶气腔10上部空腔逐渐升压形成高压腔，使得非溶解状态的空气难以排出，空气在高压状态下的溶解度大于低压状态下的溶解度，因此溶气腔10内空气于水中的溶解度会大大增加，从而完成溶气。流向空化件2的水中溶解有大量空气，从而空化件2能制出大量微气泡。
这里要强调的是，虽然在出口12处形成水封后，出口12处仍向空化件2排水，但是入口11处仍源源不断地进水，因此溶气腔10内水位仍在不断上升，导致水面上方空气空间逐渐减小，当溶气罐1内的气压逐渐上升至临近进水水压后,出水流速等于入水流速。
此外，由于入口11位于出口12的上方，入口11进水时水从上方冲向水面，使水面激荡，同时带入部分高压空气，可以增加空气与水的动态接触面积。而且由于入口11与出口12在水平方向上是错开的，水流在溶气腔10内的流动路径较长，一方面减少了入水水流冲击产生的气泡被水流裹挟而从出口12流出，另一方面增加了激出的气泡在水体中的溶解时间、接触面积。
相对于现有技术中采用水流激发板设置在入口11与出口12之间的方案来讲，本申请实施例仅是通过在水平方向上错开入口11、出口12，就能达到同样的效果，利用溶气腔10底壁或者水面充当水流激发板。本申请实施例的溶气腔10中，可以设置水流激发板以进一步增强水激发作用，也可以省去水流激发板以提高溶气罐1的可制造性。
在一些可选的实施例中，如图18所示，在水平方向上，挡板3至少部分位于入口11和出口12之间，可以对从入口11流入的水在朝向出口12流动的过程中起到拦截的作用。
进一步地，如图19所示，挡板3上设有缝隙31，或者挡板3上设有通孔，或者挡板3上设有缝隙31和通孔，使溶解了空气的水流过，但是溶气腔10中因水花激起的气 泡则被挡下，防止大气泡流向空化件2，从而进一步减少溶气罐1中空气的浪费，避免溶气腔10内气压迅速下降而影响溶气，而且大气泡流进空化件2后，会影响空化效果。
另外，挡板3的设置，当入射水流激打到挡板3上时可以形成更多水花，而且挡板3还可以作为加强结构，增强溶气罐1承压能力。
这里提到的挡板3至少部分在水平方向上位于入口11和出口12之间，是指挡板3可以如图18所示完全位于入口11和出口12之间，挡板3还可以仅部分位于入口11和出口12之间。例如，挡板3可以形成为弧形板或者球面板，挡板3罩在出口12处，此时挡板3仅部分位于入口11和出口12之间。
在一些具体实施例中，在水平方向上挡板3全部位于入口11和出口12之间，这样可以降低制造难度。
如图18和图19所示，在本实施例中，挡板3形成为平板，且垂直连接在溶气罐1的底壁上。由此，不仅能较好阻拦水流激发产生的气泡流出溶气罐1，又能方便生产和制造。平直的挡板3无论是一体形成在溶气罐1上，还是通过插接或者焊接等方式固定到溶气罐1上，都要比曲面板要容易得多。当然，这也不排除在本申请的其他实施例中，挡板3形成倾斜板、双层中空板，或者形成为上述提到的弧形板、球面板等等。
具体地，如图19所示，挡板3上缝隙31形成为上下方向的竖条状，这也能极大提高微气泡发生器100可制造性的结构。图19中缝隙31仅为一条，其他实施例中，挡板3可以形成为具有多条缝隙31的格栅板。
在另一些实施例中，挡板3为具有多个通孔的多孔板29，或者挡板3上既设有缝隙31又设有通孔。
在一些具体实施例中，当挡板3上设有缝隙31时，缝隙31的宽度小于等于50mm。可以理解的是，挡板3上的缝隙31的宽度需要较小，以避免水流激发形成的气泡穿过缝隙31。优选的，缝隙31的宽度尺寸范围为1-10mm。当然，缝隙31的大小也可以根据实际情况选择，并不限于上述范围。
可选地，挡板3与出口12之间的水平距离大于挡板3与入口11之间的水平距离，也就是说在水平方向上挡板3更靠近入口11，从而保证了挡板3对水流激发水泡的阻挡作用，从而保证了溶气罐1的溶气效果。优选的，挡板3与入口11之间的水平距离小于50mm。
当溶气罐1内的空气逐渐溶解，溶气罐1内部的空气会逐渐减少。每次使用完微气泡发生器100后，微气泡发生器100停止进水，此时可以打开控制阀4，使溶气腔10内快速恢复常压。并且，由于溶气腔10内停止进水时，空气含量低，溶气腔10内气压低于外部大气压，空化件2甚至与空化件2相连的管道内的微气泡水，都可能被吸回溶气腔10中。之后恢复常压下的溶气腔10，会使内部残留的水再从打开的辅助口18或者空化件2排出。经历此过程后，即使溶气腔10内还有些许残留，残留水量不会太多，溶气罐1内有充足的空气，由此保证了微气泡发生器100能下次使用时溶解足够的空气。
上述实施例中提出溶气罐1要将空气溶解于水中，是将空气作为一种溶质溶解于水 中，即空气以离子形态分散于水分子中。溶解的状态分散空气离子，水分子中空气离子较均匀。此后经空化效应析出的气泡，在形成初期大部分只有纳米级、微米级大小，这才是我们的微气泡发生器100所希望获得的微气泡。带有微气泡的水即使在流动到最终使用场所后，微气泡相互溶和了，得到的大部分微气泡仍能保持在毫米级甚至更小，其效果才是最佳的，其爆破能量才能有效传达到毫米级、微米级大小的纤维之间、洗涤剂微粒上。
而且如果是强行注入水中的气泡，气泡爆裂的时间过快，无法参与整个洗涤过程。溶解于水中的空气通常在空化件2中析出不完全，在整个洗涤过程中溶解于水中的空气会慢慢补充微气泡，从而源源不断的有微气泡水的产生，到达洗衣全程微气泡的参与，提高衣物处理装置洗涤能力、漂净能力。
需要说明的是，空气相对于水属于难溶气体。溶解于水中的空气量与通入空气量的百分比称为溶气效率，溶气效率与温度、溶气压力及气液两相的动态接触面积有关。改变水温或者空气温度的方法，实现起来较困难。常见的提高溶气效率的方法是采用增压泵向溶气腔10里增压，但是要配置各种阀门，因此配置增压泵成本过高。
现有技术中还有的方案是，在溶气装置中设置双进口，一个进口用来进水，另一个进口用来在进水的同时进气。它要将空气注入流动状态的水中，必须要增压泵将空气压入水中。该方案中因为空气进口位于空化件2的下方，进入的气泡会迅速朝向空化件2流动而挤出，溶气罐1里没有提供空间让气泡慢慢溶解，溶气效果并不理想。利用增压将空气注入水中的方式，相当于直接将大气泡压入水中。这种大气泡在水中停留时间短，溶解时间不足。即使在通过空化件2时，大气泡被空化件2挤成更多小气泡，但是小气泡尺寸在毫米级甚至更大，会迅速破裂释放。
本申请的微气泡发生器100，利用溶气腔10出入水流流速差，以及入口11与出口12的高低差，在出口12处形成水封，使溶气腔10逐渐升压形成高压腔，从而能提高溶气量。控制阀4的设置，使微气泡发生器100每次使用后，能使溶气腔10内排出残水、补足空气。
本申请的微气泡发生器100的空化件2与洗涤剂盒300相连，将微气泡水导向洗涤剂盒300再流向盛水桶，能减少盛水桶上连管数量，一方面便于密封，另一方面高集成度结构可以减小体积，无需安装多个阀门，用较为简单的结构实现了微气泡的发生，有利于提高结构紧凑性、集成度以及稳定性。上述微气泡发生器100，无需安装多个阀门，成本低、微气泡制造效果好。洗涤水中含有大量的微气泡，降低了洗涤剂的用量，节约了水电资源，减少了衣物上残留的洗涤剂。
在本申请实施例中，溶气罐1可以形成为任何形状，在此不对溶气罐1的形状做出具体限定。但溶气罐1需保证在溶气工作时除出口12外，溶气罐1的其他位置需要具有良好的密封性。
具体地，溶气腔10垂直于入口11部分的截面积较小，可以理解的是，当水流进入溶气腔10内，入射水流会击打溶气腔10内壁以及溶气腔10内液面。这个现象会产生 更多水花，而水花的产生则有利于将水体带入上方的高压空气中，增加了空气在水体中的溶解的速度。而溶气腔10垂直于入口11部分的截面积较小，有利于入口11入射水流击打水面过程中产生的水花，与溶气腔10内壁产生相对强的物理作用，从而实现水体能够较快的溶解空气。
如图18-图19所示，入口11位于溶气罐1的最顶部或者靠近最顶部；出口12位于溶气罐1的最底部或者靠近最底部；辅助口18位于溶气罐1的最底部或者靠近最底部。
在一些可选实施例中，如图18-图19所示，入口11的入射方向是竖直向下的，入水水流沿竖直方向射入溶气腔10内，这样既增加了水花的产生，从而加快了空气溶解速度，还利于溶气罐1批量生产的可制造性。当然，在本申请的其他实施例中，入口11的入射方向也可以是倾斜的，即水流的入射方向可以与竖直方向呈一定夹角，这样入射水流冲击面积非常大。
在一些实施例中，在水平方向上，如图18所示，入口11与出口12位于溶气罐1的两端，由此使得水流在溶气罐1内部的流动路径进一步加长，进一步减小水流击出的水泡通过出口12流出。
溶气腔10在水平方向上的截面为方形，入口11和出口12对应方形两端的直线距离最远处设置。例如，溶气腔10在水平方向上的截面为长方形，入口11和出口12位于长方形的长边的两端。这种溶气罐1容易加工，而且在装配时容易布局。当然，在本申请的其他实施例中，溶气腔10的截面形状可以形成为任何形状并不限于长方形、菱形或其它不规则方形。
有利地，如图18所示，入口11位于溶气腔10的最上方，可保证入射水流能激起更多水花，提高溶气效果。可选地，出口12位于溶气腔10的最下方，这样可使出口12能尽快形成水封。
在一些实施例中，入口11与溶气腔10的至少一个侧壁之间的距离小于50mm。即入口11在工作状态时，在垂直方向上到水面的投影，与至少一个溶气腔10内壁面的距离小于50mm。入口11水流更容易撞击溶气罐1的侧壁产生水花，从而提高溶气罐1的溶气效果。可选地，入口11与溶气腔10的至少一个侧壁之间的距离在1-20mm之间。当然，在本申请的其他实施例中，溶气腔10的内壁可以设置出内凸筋等结构，使激起水花更加容易。
在本申请实施例中，溶气罐1由两个溶气半壳13相互扣合设置，入口11设在其中一个溶气半壳13上，出口12设在另一个溶气半壳13上。将入口11和出口12分别设置于两个溶气半壳13上，容易成形，且每个溶气半壳13的强度也不会过低。这种溶气罐1可制造性强，便于批量生产，加工成本低。
在一些具体实施例中，两个溶气半壳13通过焊接或者胶接连接，从而保证密封性。在另一些具体实施例中，溶气罐1为塑料件，例如每个溶气半壳13均为一体注塑成型件。
其中，溶气罐1的上部设有连通溶气腔10顶部的入水管14，溶气罐1的下部设有 连通溶气腔10底部的出水管15，入水管14和出水管15水平设置，这样能便于装配。例如，当微气泡发生器100与洗涤剂盒300集成使用时，溶气罐1安装于洗涤剂盒300后方，入水管14和出水管15水平设置使装配更加容易。
如图18-图19所示，在本实施例中，两个溶气半壳13上下设置，入水管14一体形成在上方的溶气半壳13上，出水管15一体形成在下方的溶气半壳13上，这样加工的便利性、密封性都能保证。
具体地，两个溶气半壳13在拼接处通过台阶面16接触配合，这样不仅增大了两个溶气半壳13接触处的接触面积，也提高了接触强度。另外台阶面16接触配合，使两个溶气半壳13的接触面中，至少部分接触面与溶气腔10内壁的压力相垂直或者接近垂直。这就使两个溶气半壳13在拼接处，因内部高压反而会越压越紧，避免因内部高压导致拼接处裂开、漏气。
进一步地，溶气罐1的外表面设有横纵交错设置的加强筋17，这样能增加溶气罐1的强度，避免因内部高压而变形、漏气。
本申请实施例中，空化件2可以采用现有技术中已经公知的空化装置的结构，例如采用超声波发生器等，例如空化件2内形成至少一个文丘里通道25。
在一些可选实施例中，如图21所示，空化件2为设有多个微孔的孔板29。由此，可以较为简单的将经过空化件2的水流中溶解的空气析出，并且制成气泡。具体地，孔板29上微孔的半径为0.01mm-10mm。经试验证明具有上述参数的孔板29的空化作用较好，能够产生更多的气泡。当然，孔板29的具体参数可以由工作人员根据实际工况进行调整，并不限于上述范围。
在另一些可选实施例中，如图20所示，空化件2包括文丘里管28，一个文丘里管28内形成一个文丘里通道25。由此，可以较为简单地将经过空化件2的水流中溶解的空气析出，并且制成气泡。采用文丘里管28作为空化件2，不必设计多余的水泵、加热装置或者控制阀4门等等，极大地简化了空化件2的结构，降低了生产成本，且文丘里管28对进水方式没有额外要求，使得空化件2能够较为容易地产生大量气泡。
在一些具体实施例中，如图22-图24所示，空化件2形成为具有多个文丘里通道25的变形结构。如图22所示，空化件2大体为一种柱体，空化件2内设置了多个文丘里通道25。这样的结构一方面加长文丘里通道25的路径长度，有利于文丘里效应发挥的时间充足性，另一方面方便加工制造，方便装配，尤其与管口连接时非常便利。
具体而言，如图24所示，空化件2内文丘里通道25在水流流动方向上依次包括：渐缩段251、喉管252和渐扩段253，渐缩段251在朝向喉管252的方向上直径逐渐减小，渐扩段253在远离喉管252的方向上直径逐渐增大，喉管252在文丘里通道25内过流面积最小。
具体地，空化件2形成为柱形，空化件2的相对两端分别形成有分流槽261和汇流槽262，文丘里通道25形成在分流槽261的底壁和汇流槽262的底壁之间。
空化件2一般利用管路连接进入衣物处理装置，因此空化件2的出端内径可选在 5-15mm之间。进一步可选地，空化件2的出端内径控制在7-10mm之间。在图24的示例中，汇流槽262的直径可选在5-15mm之间，进一步可选在7-10mm之间。
可选地，文丘里通道25为1-30个，进一步可选地，文丘里通道25为4-6个。空化件2作为关键部件，需要承担对衣物处理装置入水水流的处理，而衣物处理装置入水一般采用生活自来水。生活自来水流量一般为5-12L/min，水压一般为0.02-1Mpa。更常用的，流量一般为8-10L/min，水压一般为0.15-0.3Mpa，因此，空化件2内文丘里通道25的数量可选在4-6个。
空化作用的相关原理为：
渐缩段251进端处的平均速度、平均压力和截面积分别为V1、P1、S1，喉管252处的平均速度、平均压力和截面积分别为V2,P2,S2,水的密度为ρ,在工作状态下，衣物处理装置以自来水为工作介质，满足关系式：S1*V1＝S2*V2。
利用伯努利定律和连续性方程可以得到关系式：V12/2+P1/ρ＝V/2+P2/ρ。
在此过程中通过控制S1与S2的变化，使得在文丘里通道25中，喉管252处流速增大，喉管252处压力变小，因此溶解在水中的空气以微气泡的形式释放出来。
渐扩段253作为扩散段，比较理想的扩散应该使得流体逐渐减速，因此渐扩段253需要一定的长度。可选地，渐扩段253的长度大于渐缩段251的长度，进一步可选地，渐缩段251与渐扩段253的长度比为1:2-1:4，更进一步可选地，渐缩段251与渐扩段253的长度比为1:3-1:4。
由于文丘里通道25需要分布在截面积相对有限的空化件2中，因此文丘里通道25各处直径有限。可选地，喉部的直径为0.7-2.0mm，进一步可选地，喉部的直径为0.9-1.1mm。另外，渐缩段251、渐扩段253的端部直径均大于喉管252直径，至少要大0.1mm。可选地，渐缩段251的远离喉管252的端部直径范围在1-4mm，渐扩段253的远离喉管252的端部直径范围在1-4mm。进一步可选地，喉管252的直径与渐缩段251的端部直径比值约为1：1.3-2。喉管252的直径与渐扩段253的端部直径比值约为1：1.3-2。
进一步地，如图22-图24所示，为方便安装，空化件2的一端形成有螺纹段231，螺纹段231可以是内螺纹也可以是外螺纹。在图22和图23的示例中，空化件2在与溶气罐1相连的一端的螺纹段231为外螺纹，通过螺纹旋接在溶气罐1上，连接非常方便。
在另一些具体实施例中，如图25所示，空化件2包括：空化壳23和空化球24。空化壳23内设有过水腔20，空化壳23具有出入水流的空化进口21、空化出口22，空化进口21连接溶气罐1的出口1212。空化球24可活动地设在过水腔20内，从空化进口21流入的水可推动空化球24堵在空化出口22处，且当空化球24堵在空化出口22处时，空化球24与过水腔20的内壁之间形成文丘里通道25。
当空化球24堵在空化出口22时，空化球24与过水腔20的内壁之间设有连通空化出口22的文丘里通道25。此处表明，空化球24未将空化出口22完全封死，而是留出文丘里通道25以使得溶解有空气的水流逐渐从空化出口22流出。
通过在空化出口22前的过水腔20中设置活动的空化球24，当空化进口21中不断通入溶解有空气的水流，不断通入的水流沿着过水腔20的内壁流动，遇到空化球24后，会推着空化球24向着空化出口22移动，使得空化球24移动到空化出口22前，并逐渐止抵在空化出口22上，形成文丘里通道25。
溶解有空气溶质的水流在通过文丘里通道25时，过流面积会先缩小、后增大。过流面积缩小，带气体溶质的水流的流速增大时，压力减小。过流面积增大，气体溶质的水流的流速减小时，压力增大。文丘里通道25内会产生文丘里效应，空气从溶质状态析出形成微气泡。而且水流使空化球24保持止抵在空化出口22上，也使溶解有空气溶质的水流更快地从文丘里通道25中流出。
在这个过程中，不断通入的水流量大于流出的水流量，而过水腔20作为气闭腔，当其空化出口22前止抵有空化球24时，其内部的压力会增大，强化空化效应。
采用这种空化件2，不仅成本较低，加工难度也低，而且还具有其他空化结构所不具备的优势。空化球24是可活动球体，当微气泡发生器100停止工作后，水流量降低，没有水流的抵压空化球24会离开空化出口22，这样能使微气泡发生器100内剩余的水尽快排除。这样一方面方便溶气罐1内预存空气，另一方面避免积水沉积而滋生过多细菌。另外，这种空化件2也方便清洁。
下面结合附图1-图27详细描述根据本申请的衣物处理装置的一些具体实施例。
在本申请一个具体实施例中，如图2-图3以及图26所示，衣物处理装置为洗衣机，总进水管200连接自来水管，总进水管200分别与洗涤剂盒300的洗涤进口以及微气泡发生器100的入水口101相连，微气泡发生器100的出水口102通过第二微气泡接管522与洗涤剂盒300底部的进水汇管51相连，辅助口18设于溶气罐1的上部且高于溶气腔10的出口12，辅助口18通过洗涤剂盒300上的回气通道301与大气连通。衣物处理装置的工作过程如下：
自来水通过进水阀210流经管道进入溶气罐1，在溶气罐1内部充分激发溶解内部空气，在溶气罐1内部形成空气溶液。高深度空气溶液经过空化件2时，形成微气泡水。
微气泡水通过第二微气泡接管522，途径洗涤剂盒300底部的进水汇管51，流入衣物处理装置内桶(即盛水桶)，保证微气泡水以最短的路径流入内桶，参与衣物的洗涤、漂洗，减少微气泡的损失。微气泡较长时间和衣物进行充分接触，衣物上污渍被充分剥离，达到洗净衣物的目的。
当自来水停止进水，溶气罐1内有部分残留水，为保证循环的下次使用有充足的空气进行溶解，控制顶部控制阀4打开，使辅助口18处于打开状态，打开后的辅助口18通过回气通道301与大气相通，从而实现向溶气罐1内补充空气的目的，便于下次使用或便于进行循环利用，而溶气罐1内部的残留水在自重的作用下，从出水口102排出，并通过第二微气泡接管522流入盛水桶中或其他残水排除部位，从而排空残留水。
在本申请另一个具体实施例中，如图6至图10以及27所示，衣物处理装置为洗衣机，总进水管200连接自来水管，总进水管200与微气泡发生器100的入水口101相连， 微气泡发生器100的出水口102通过第一微气泡接管521与洗涤剂盒300的洗涤进口相连，辅助口18设于溶气罐1的下部且低于溶气罐1上的出口12，辅助口18通过排水管53与洗涤剂盒300底部的进水汇管51相连。衣物处理装置的工作过程如下：
自来水通过进水阀210流经管道进入溶气罐1，在溶气罐1内部充分激发溶解内部空气，在溶气罐1内部形成空气溶液。高浓度空气溶液经过底部的出口12(含有空化件2)时，形成微气泡水。
微气泡水在溶气腔10上部高压的作用下，经空化件2沿第一微气泡接管521向上流向洗涤剂盒300的洗涤进口，进入洗涤剂盒300。微气泡水冲击洗涤剂腔内的洗涤剂(或洗衣液、洗衣粉、柔顺剂等)，由于微气泡的爆破，洗涤剂会得到充分溶解，并且溶解为更细小的颗粒，混合有洗涤剂的微气泡水经过洗涤剂盒300底部的进水汇管51流向洗衣机内桶。一方面微气泡水充分溶解的洗涤剂快速剥离衣物上的污渍，同时微气泡本身的爆破也会使衣物上的污渍快速剥离，从而有效提高洗衣机的洗净能力。
当溶气罐1停止进水，微气泡水逐渐停止产生，此时控制底部的控制阀4打开，第一微气泡接管521内的残留水回流到溶气罐1中，由于出口12的位置高于辅助口18的位置，洗涤剂盒300内的空气通过第一微气泡接管521流经处于常开状态的出口12，从而充满溶气罐1中，使溶气罐1内空气再次得到补充；而溶气罐1内的残留水在气压差以及自重的作用下，从辅助口18流出，并经过排水管53流入衣物处理装置内桶中或其他残水排除部位，从而排空残留水。
根据本申请实施例的衣物处理装置的其他构成例如电机和减速器、排水泵等结构以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
