  • Micro-bubble usually refers to tiny bubbles with a diameter of less than fifty micrometers ( ⁇ m) when the bubbles occur. Microbubbles may also be referred to as micro-/nano-bubbles, microbubbles or nano-bubbles, depending on their diameter range. Because of their low buoyancy in the liquid, microbubbles stay in the liquid for a long time. Furthermore, the microbubbles shrink in the liquid until they finally break up, creating smaller nanobubbles. In this process, the rising speed of the bubbles becomes slow because the bubbles become smaller, resulting in high melting efficiency. When the microbubbles are broken, high-pressure and high-temperature heat is locally generated, thereby destroying foreign objects such as organic matter floating in the liquid or adhering to objects.

气泡发生器及具有其的洗涤设备 技术领域
本发明涉及洗涤领域，具体地涉及气泡发生器及具有其的洗涤设备。
背景技术
微气泡(micro-bubble)通常是指气泡发生时直径在五十微米(μm)以下的微小气泡。微气泡根据其直径范围也可以称为微纳气泡(micro-/nano-bubble)、微米气泡或纳米气泡(nano-bubble)。微气泡由于其在液体中的浮力小，因此在液体中滞留的时间比较长。而且，微气泡在液体中会发生收缩直到最后破碎，生成更小的纳米气泡。在这个过程中，气泡因为变小所以其上升速度变得缓慢，导致融化效率高。微气泡在破碎的时候局部会产生高压和高温的热，由此能够破坏漂浮在液体中或附着在物体上的有机物等异物。另外，微气泡的收缩过程还伴随负电荷的增加，负电荷的高峰状态通常是在微气泡的直径处于1-30微米的时候，因此容易吸附漂浮在液体中的带正电荷的异物。结果就是异物在其由于微气泡的破碎而被破坏之后会被微气泡吸附，然后慢慢浮到液体表面。这些特性使得微气泡具备很强的清洗和净化能力。目前，微气泡已经被广泛应用于洗衣机等洗涤设备中。
例如，中国发明专利CN108396516B公开了一种波轮洗衣机，该波轮洗衣机具有设置在盘座中的注水装置。该注水装置具有连接到供水源的连接口、注水盒、和布置在连接口与注水盒之间的细微气泡发生器。具体地，CN108396516B公开的细微气泡产生器具有圆筒状喷管，在喷管内沿着水流方向形成有直径变小锥形通道部、突出部(形成节流孔)和混合腔(直径大于节流孔的直径并且保持不变)。在电磁供水阀打开后，来自主水管的水流在流过这种细微气泡产生器时被迅速地降压，使得在水流中的空气被析出而在水中产生微气泡，从而形成微气泡水。该微气泡水进入洗衣筒被用于衣物的洗涤。然而，这种细微气泡产生器只能依靠流过其的液体内部所携带的极为有限的空气来产生细微气泡，因此，该细微气泡产生器不能提供含有足够多微气泡的微气泡水。
又如，中国发明专利CN111417455A公开了一种细微气泡产生器，该细微气泡产生器包括流路构成部和减压部件，流路构成部构成能够供液体通过的流路，减压部件具有碰撞部，碰撞部嵌入流路构成部，通过局部地缩小流路的截面面积，使通过流路的液体中产生细微气泡。该细微气泡产生器还具备：与减压部件的负压产生部位相连的出口；设于流路构成部的、用于 导入外部空气的外部空气导入口；以及使外部空气导入口与出口连通的外部空气导入路径。可以通过负压产生部位的负压将外界空气吸入。但该细微气泡产生器的空气吸入量有限，微气泡产生效果不佳，从而导致洗净效果仍然有很大的提升空间，残留的洗涤剂可能对用户的健康产生隐患。

在上述气泡发生器的优选技术方案中，所述下壁的靠近所述插件的第二端的部分径向向外扩大以便形成位于所述插件室下游的辅助出水口。

优选地，在环形台上设置两个彼此间隔开的缺口，可以从不同方位吸进空气，从而增加进气量。
优选地，在插件的第一端上设有从第一端的端面沿着中心线方向在第一端内延伸第一预定深度的环形凹槽，且该环形凹槽与进气通道连通。 该环形凹槽既可以方便生产脱模，又可以存储一定量的空气，可为负压腔提供更多的空气量。
优选地，在所述插件室的径向壁上形成有具有第二预定深度的径向壁凹槽，该径向壁凹槽与环形凹槽相对并且与进气通道连通。该径向壁凹槽使得盒体具有均匀壁厚，保证盒体的成型。同时也扩大了进气通道的容积，进一步增加了空气存储量，保证负压腔可以吸入足够多的空气。
优选地，气泡发生器还包括由板状本体和压腿构成的压板，该压板通过压腿将微气泡起泡网压靠在插件的第二端上，并在微气泡起泡网与板状本体之间形成接收微气泡水的微气泡水室。通过该微气泡水室可将微气泡水引向微气泡水出口。而且，板状本体可充当盒体的出水部的端盖。
优选地，多个压腿布置成与插件第二端匹配的环形，相邻压腿之间形成有可以出微气泡水的周向间隙，该周向间隙可以增加出微气泡水的自由度。
优选地，出水部包括围绕插件室的周向外壁和周向内壁，周向外壁由上壁、下壁、左壁和右壁构成，周向内壁沿着上壁、左壁和右壁中的至少一部分平行地延伸，吸气槽形成在周向外壁和周向内壁之间并且经由形成在周向内壁上的进气口与进气通道形成空气连通。将吸气槽布置在相互隔开并平行布置的周向外壁和周向内壁之间并在周内内壁上设置可连通负压腔的进气口，既提供了足够大的吸气槽，又可以避免吸气槽和进气口被堵塞，从而保证足量空气能够顺畅地流入负压腔。
优选地，出水部的下壁的靠近插件的第二端的部分径向向外扩大以便形成辅助出水口。来自溢流口的水和/或从压腿之间的周向间隙流出的微气泡水可从该辅助出水口排出。
优选地，沿着水流的流向，负压腔的内径逐渐缩小，形成直径渐缩锥形腔，并且混合腔的内径逐渐扩大，形成直径渐扩锥形腔。负压腔的配置用于增强空气的吸入，而混合腔的配置则用于提高空气与水的混合程度。
优选地，在围成混合腔的锥形壁的外周上设有在周向上彼此间隔开的多个加强肋板，可以增加插件混合腔部位的强度，也便于插件的工艺成型。
优选地，在插件的第二端上设置多个溢流口。当喷管内的水压不足，因此水流无法快速贯穿微气泡起泡网时，水流能够从这些溢流口流出，避免了因水流在混合腔内累积而堵住微气泡起泡网和无法吸气的问题，从而保证气泡发生器持续产生微气泡水的高可靠性。
优选地，在进水部内壁上设有多个管道加强筋，可以加强进水部的强度，也可以对置于内部的进水管起到定位作用。
优选地，微气泡起泡网为多层网结构，通过与每层网结构上的微米细孔相配合，能够显著减小微气泡的直径并且增加微气泡与水的混合程度。
为了解决现有技术中的上述问题，即为了解决现有洗涤设备洗净效果不好并且残留的洗涤剂可能对用户的健康产生隐患的技术问题，本发明还提供一种洗涤设备，该洗涤设备包括：箱体、布置在所述箱体内的洗涤筒、安装在所述箱体上并且连接到外部水源的进水管、以及如上所述的任一种气泡发生器，该气泡发生器通过连接机构与所述进水管形成连接并且为所述洗涤筒提供微气泡水。通过将微气泡水喷入洗涤筒中，能够帮助提高洗涤设备的洗净能力，同时能够节省洗涤处理剂的用量，因此也有利于用户的健康。
在上述洗涤设备的优选技术方案中，连接机构包括：可与进水端连接的连接套、可套在进水管上且设有连接槽和多个卡爪的卡座、以及可与所述箱体连接且可卡在所述连接槽中的固定件。连接槽环绕所述卡座的外周壁，卡爪形成在所述卡座的一端上并且沿所述卡座的周向形成均匀间隔，卡座通过卡爪与连接套连接。该连接机构连接进水管与气泡发生器的同时又将气泡发生器与箱体连接，这样通过该连接结构可以实现在进水管、气泡发生器和箱体三者之间形成连接。使得进水管、气泡发生器和箱体三者在洗涤设备中的安装更加牢固可靠。

为了解决现有注水盒的微气泡产生率不高的技术问题，本发明提供一种气泡发生器5。该气泡发生器5包括：盒体51，其包括进水部511、出水部514、和位于进水部511与出水部514之间的节流孔513，进水部511设有进水端111，出水部514设有插件室146；插件53，其配置成可被容纳在插件室146内，在插件53内设有负压腔531和位于负压腔531下游的混合腔532，插件53的第一端539a定位靠近节流孔513并且在第一端539a上形成有围绕负压腔531并沿中心线方向向外延伸预定高度的环形台391，在环形台391上形成有至少一个缺口392，环形台391抵靠插件室146的径向壁512以在第一端539a与插件室146之间形成空气连通出水部514外部的进气通道516，进气通道516通过至少一个缺口392与负压腔531连通，使得由节流孔513节流后的水流在负压腔531内产生的负压可将外界的空气吸入负压腔531，空气与水流在混合腔532内混合形成气泡水；以及微气泡起泡网54，其配置成将气泡水切割成微气泡水。
在本文中提及的“上游”和“下游”除非有明确相反的说明，都是相对于说明书附图中示出的水流方向C而言。在本文中提及的“上壁”、“下壁”、“左壁”和“右壁”都是针对本发明气泡发生器被水平地放置并且从出水部一侧观察气泡发生器的情况而言。除非有明确相反的说明，本文中所提及的“中心线”是指插件的中心线。
图1是本发明气泡发生器的实施例的立体示意图，图2是图1所示的本发明气泡发生器的实施例的正视图，图3是沿着图2的剖面线A-A截取的本发明气泡发生器的实施例的剖面图。如图1-图3所示，在一种或多种实施例中，气泡发生器5包括盒体51、被容纳在盒体51中的插件53、微气泡起泡网54、和将微气泡起泡网54固定在插件53的第二端539b上的压板52。替代地，微气泡起泡网54也可通过其它合适的装置固定到插件53的第二端539b上，例如压环等结构。
如图3所示，盒体51包括进水部511、出水部514和位于进水部511与出水部514之间的节流孔513。进水部511与出水部514形成一体，并且共用径向壁512。在一种或多种实施例中，从径向壁512上沿着水流方向C向上游延伸形成具有第二预定深度的环形的径向壁凹槽517。在一种或多种实施例中，径向壁凹槽517的截面大致成V型。替代地，径向壁凹槽517的截面也可采用其他合适的形状，例如U型横截面。在一种或多种实施例中，节流孔513形成在径向壁512的中心位置。优选地，在径向壁512上形成围绕节流孔513并且向下游稍微突起的锥形凸台512a，该锥形凸台的外直径沿着水流方向C逐渐缩小。替代地，节流孔513可形成在进水部511内。
在一种或多种实施例中，进水部511为大致圆筒状。如图3所示，进水部511具有进水端111，并且进水部511通过该进水端111可连接到外部的水源，例如自来水。替代地，进水部511也可采用其它合适的形状，例如具有椭圆形横截面的进水部。在一种或多种实施例中，在进水部511内分别形成有直通道113和加压通道112。所谓“直通道”是指其直径沿着延伸长度保持不变的通道。如图3所示，沿着水流方向C，直通道113从进水端111延伸到加压通道112，而加压通道112从直通道113延伸到节流孔513。直通道113的直径沿其延伸长度保持不变。加压通道112的直径则沿着水流方向C逐渐缩小，形成锥形通道。该锥形通道可对流过其中的水流进行加压，加压后的水流再通过节流孔513可被迅速膨胀地喷出到下游并产生很大的负压。可选地，在进水部511内省去直通道，使得加压通道112可从进水端111一直延伸到节流孔513。
图4是本发明气泡发生器的盒体的实施例的第一立体示意图；图5是本发明气泡发生器的盒体的实施例的后视图；图6是沿着图5的剖面线B-B截取的本发明气泡发生器的盒体的实施例的剖面图。如图4-图6所示，在一种或多种实施例中，在进水端111外周上设有环形连接套槽111a，并且进水端111的内壁直径大于直通道113的孔径。如图4-图6所示，在一种或多种实施例中，在直通道113和加压通道112内壁上设有四条管道加强筋114，并且管道加强筋114沿周向均匀分布，例如分别布置在竖直方向和水平方向上。替代地，在直通道113和加压通道112内壁上可设置多于或少于四条的管道加强筋114，例如，沿周向均匀间隔地设置三条或者六条管道加强筋114。如图4-图6所示，在一种或多种实施例中，大致处于水平位置的两条管道加强筋114上朝向进水部511的中心方向分别延伸出两条进水管限位条115。替代地，也可以将进水管限位条115设置位于竖直方向上的两条管道加强筋114上。
如图1至图3所示，出水部514包括插件室146、沿插件室146的外周延伸并与其形成空气连通的吸气槽143、和位于插件室146下游的出水口147。插件室146在其上游直接连通节流孔513。插件室146垂直于水流方向C的横截面为大致圆形。在一种或多种实施例中，沿着水流方向C，出水部514为具有上游端、下游端、和位于上游端和下游端之间的四个侧面的大致中空的盒状结构。上游端连接到进水部511，而下游端为敞开的开口。插件室146在上游端和下游端之间延伸。如图1和图2所示，在出水部514的四个侧面上分别形成有上壁141a、下壁141b、左壁141c、和右壁141d。上壁141a、下壁141b、左壁141c、和右壁141d一起构成周向外壁141。该周向外壁141在周向上围绕整个插件室146。如图3所示，在一种或多种实施例中，下壁141b的靠近出水部514下游端的部分在径向上逐渐向下(相对于图3所示的方位)扩大，并且通过该扩大部分围成的空间形成辅助出水口147。替代地，在出水部514的下游敞开端上可形成其它形式的辅助出水口。
如图1和图2所示，在一种或多种实施例中，在周向外壁141与插件室146之间还形成有周向内壁142。周向内壁142与周向外壁141大致平行并且相互之间形成具有预定距离的间隙，该间隙构成吸气槽143。该吸气槽143朝向出水部514的下游端完全敞开，从而允许外界空气自由、足量地进入吸气槽143。相应地，在周向内壁142的位于出水部514上游端的部分上设有穿过周向内壁142的进气口145，从而使插件室146与吸气槽143之间可形成空气连通。进气口145可为适当尺寸的狭长孔，也可为一个或多个圆形孔或矩形孔，例如两个圆形孔或矩形孔。进气通道516通过进气口145空气连通吸气槽143，因此可与出水部514的外部形成空气连通。替代地，进气通道516也可通过设置在出水部上的其他形式的空气通道与出水部514的外部形成空气连通。如图1和图2所示，在一种或多种实施例中，周向内壁142分别沿着周向外壁141的上壁141a、左壁141c和右壁141d延伸。相应地，周向内壁142包括中间位置围绕插件室146并且两边平行于上壁141a的内上壁142a、平行于左壁141c的内左壁142b、平行于右壁141d的内右壁142c、平行于上壁141a且在内左壁142b下端与左壁141c之间延伸的内左下壁142d、和平行于上壁141a且在内右壁142c下端与右壁141d之间延伸的内右下壁142e。因此，吸气槽143为大致U型的环槽。替代地，周向内壁142只沿着上壁141a延伸，因此只在上壁141a与内上壁142a之间形成“一”型的吸气槽143；或者，周向内壁142沿着上壁141a和左壁141c延伸，因此在上壁141a、左壁141c与内上壁142a、内左壁142b之间形成“L”型吸气槽143。类似地，周向内壁142沿着上壁141a和右壁141d延伸，因此在上壁141a、右壁141d与内上壁142a、内右壁142c之间形成“L”型吸气槽143。吸气槽143的设计为气泡发生器5提供非常畅通的空气流道，气泡发生器5因此可从外界吸入大量的环境空气。
图7是本发明气泡发生器的盒体的实施例的第二立体示意图；图8是本发明气泡发生器的盒体的实施例的前视图；图9是沿着图8的剖面线C-C截取的本发明气泡发生器的盒体的实施例的剖面图。如图7-图9所示，在一种或多种实施例中，在插件室146两侧，分别设有从盒体的上游端往下游端延伸出预设高度的固定柱148。在每个固定柱148上都设有沿该固定柱中心线延伸的纵向孔，例如用于接纳螺钉等。两个固定柱148间隔的距离超过插件室146的最大外直径，以避免与插件室146产生干涉。每个固定柱148为带通孔的圆柱体，在每个固定柱148的侧壁与内上壁142a之间形成有平行的加强肋板144。每个加强肋板144为大致L型。该L型具有连接固定柱148的长边和连接内上壁142a的短边。该L型位于下游端的部分在固定柱148的侧壁与内上壁142a之间形成实体连接，并且其位于上游端的部分在固定柱148的侧壁与内上壁142a之间留有间隙。替代地，加强肋板144可以为U型，其两个长边分别与固定柱148侧壁和内上壁142连接，且在两个长边之间形成的空间开口朝向上游端。在每个加强肋板144的位于上游端的部分上形成有与盒体51距离预 设间隙的卡扣149，并且每个卡扣149均朝向插件室146方向突起。加强肋板144为卡扣的布置提供了牢固的连接基础。基于图8所示方位，在插件室146下方设有从上游端向下游端方向延伸的弧形下限位壁140。下限位壁140为插件室146提供更大的容纳空间，并且使得插件室146下方的可接触表面积更大。在收纳插件53时，能够为插件53的对应下表面提供更大的接触面积。
图10是本发明气泡发生器的插件的实施例的第一立体示意图，而图11是本发明气泡发生器的插件的实施例的第二立体示意图。如图10和图11所示，插件53为与插件室146相匹配的大致圆柱状结构。插件53具有第一端539a和第二端539b。如图3所示，在插件53被装配到插件室146中的状态下，插件53的第一端539a被置于出水部514的上游端中，因此靠近节流孔513和进气口145。在插件53的第一端539a上沿着中心线方向从第一端539a的端面向外延伸出预定高度的环形台391。该环形台391的径向宽度小于第一端539a的端面宽度，使得当插件53被插入到插件室146中时，该环形台391抵靠径向壁512以在第一端539a与径向壁512之间形成具有大致预定高度的轴向间隙，该轴向间隙构成本发明的进气通道516。在环形台391上间隔设有两个缺口392。替代地，也可以设置一个缺口或者多于两个的缺口。进气通道516分别与缺口392和进气口145连通，因此也可与吸气槽143形成空气连通。从第一端539a的端面沿着中心线方向在第一端539a内向内延伸出第一预定深度的环形凹槽530。因此，环形凹槽530也与进气通道516连通。在径向壁512上形成的径向壁凹槽517也与空气通道516连通。环形凹槽530与径向壁凹槽517为进气通道516扩大了空气流通的空间，使得可被吸进负压腔531的空气量更充足。如图3所示，在一种或多种实施例中，在插件53的周向外壁上靠近第一端539a还设有环形的密封槽533。该密封槽533用于容纳插件密封圈534，从而在插件53与插件室146的内壁之间形成流体密封。
如图3、图10和图11所示，在一种或多种实施例中，在插件53的内部，沿着插件53的中心线，从第一端539a到第二端539b，依次形成有负压腔531、过渡孔536、混合腔532、和直筒混合腔537。环形台391围绕负压腔531。在气泡发生器5的组装状态下，负压腔531位于节流孔513的下游并且与节流孔513直接连通。径向壁512上的锥形凸台512a延伸进入负压腔531的上游端并且在径向上与环形台391之间留有间隙。负压腔531通过缺口392与进气通道516形成连通。在一种或多种实施例中，负压腔531的直径沿着水流方向C逐渐缩小，使得负压腔531形成直径渐缩的锥形腔。这种直径渐缩的锥形腔可增强对空气的吸入，使得更多的外界空气能够进入负压腔531。混合腔532通过过渡孔536与负压腔531连通。过渡孔536的直径大约与负压腔531的最小直径相同。在一种或多种实施例中，混合腔532的直径沿着水流方向C逐渐增大，使得混合腔532形成直径渐扩的锥形混合腔。在一种或多种实施例中，混合腔532由锥形壁围成，并且在该锥形壁的外周上设有沿周向间隔开 的多条加强肋321，每个加强肋321从锥形壁的外周大致沿径向向外延伸或者倾斜地向外延伸，并可达到与插件53的外周壁平齐的高度。通过设置加强肋321保证混合部的壁厚均匀，便于插件53的成型，同时也减少了插件53的制造材料，节约了成本。在该直径渐扩的锥形腔下游还形成有具有锥形腔的最大直径的附加混合腔，其被称为直筒混合腔537，使得空气与水流能够进行充分混合。在直筒混合腔537外周上的两侧设有与卡扣149配合的凸起371，以保证插件53可以稳定可靠地安装在插件室146中。替代地，插件53内可以取消直筒混合腔537。如图11所示，在插件53的第二端539b上设有多个溢流口535。这些溢流口535分布在第二端539b的环形端面上，例如位于该环形端面的中间及下部位置上，并且相互间隔预定距离。根据实际需要，相邻溢流口535之间的距离可以相同，也可以不相同。在水压不足的情况下，水流可能无法快速贯穿微气泡起泡网54，因此会累积在混合腔中。这些溢流口则允许水流通过其流出，从而能够避免因水流在混合腔内累积而堵住微气泡起泡网54和导致无法吸气的问题，从而保证气泡发生器5持续产生微气泡水的高可靠性。
如图3所示，微气泡起泡网54被压板52固定在插件53的第二端539b上。在插件53的第二端539b的端面上形成有最大直径小于第二端539b的最大直径的环形台阶。该环形台阶形成网槽538。微气泡起泡网54可被置于该网槽538中并且抵靠该网槽538。在一种或多种实施例中，微气泡起泡网54包括多层网结构，例如两层、三层或更多层。每层网结构具有至少一道网孔的直径达微米级。优选地，网孔的直径在0～1000微米之间；更优选地，网孔的直径在5～500微米之间。滤网可以是塑料栅栏，金属网，高分子材料网，或者其它合适的孔网结构。塑料栅栏通常是指高分子栅栏，其由高分子材料一体注塑成型，或者先将高分子材料制成板，再在该板上通过机加工产生微孔结构而形成塑料栅栏。高分子材料网通常是指通过先将高分子材料制成丝，再用这丝编织成的具有微孔结构的网。高分子材料网可以包括尼龙网，棉纶网，涤纶网，丙纶网等。替代地，网结构可以是能够产生微气泡的其它网孔结构，例如由两个非微米级的蜂窝状结构组成的网孔结构。当气泡水流过网孔结构时，该网孔结构对气泡水产生混合和切割的作用，从而产生大量微气泡水。
图12是本发明气泡发生器的压板的实施例的第一立体示意图，而图13是本发明气泡发生器的压板的实施例的第二立体示意图。如图12和图13所示，在一种或多种实施例中，压板52具有板状本体521和从板状本体521的内侧面521a向外延伸的压腿522。在气泡发生器5的组装状态下，板状本体521的内侧面521a面朝微气泡起泡网54，因此被称为“内侧面”。相应地，板状本体521的背对微气泡起泡网54的侧面被称为外侧面521d。在板状本体521的大致中心位置形成有微气泡水出口526。该微气泡水口526的直径与插件53的 第二端539b的端面直径大致一致。从微气泡起泡网54流出的微气泡水主要从该微气泡水出口526喷出。板状本体521还具有上边缘521b和下边缘521c。在气泡发生器5的组装状态下，板状本体521基本覆盖出水部514的下游端，板状本体521的上边缘521b与周向内壁142的上壁142a相邻，而板状本体521的下边缘521c靠近周向外壁141的下壁141b和辅助出水口147。因此，板状本体521可充当出水部514的下游端盖，只需暴露辅助出水口147和吸气槽143。可选地，板状本体521的上边缘521b和两侧边缘可向内延伸出部分形成压板引导边527，在气泡发生器5的组装状态下，该压板引导边527起定位和引导作用。如图12和图13所示，在一种或多种实施例中，压板52通过螺钉或螺丝固定到盒体51的出水部514上。相应地，在板状本体521上形成两个固定孔524。这两个固定孔524分布在板状本体521的左右两侧，通过螺丝或螺钉可延伸穿过固定孔524将压板52固定在出水部514的固定柱148上。替代地，压板52也可采用其它合适方式与出水部514固定在一起，例如通过卡扣结构。
如图12和图13所示，在一种或多种实施例中，压腿522包括多个压腿，这些压腿布置成一个环形，该环形对应插件53的第二端539b的端面，因此压板52可通过这些压腿将微气泡起泡器54压靠在位于插件53的第二端539b上的网槽538中。通过这些压腿，在板状本体521与微气泡起泡网54之间形成可接收微气泡水的微气泡水室515。相邻压腿之间形成周向间隙523，以允许微气泡水从微气泡水室515经由这些周向间隙523流向辅助出水口147。如图12所示，在一种或多种实施例中，多个压腿522包括一个第一压腿522a和多个第二压腿522b。沿着周向方向，第一压腿522a的宽度大于每个第二压腿522b。在组装气泡发生器5的时候，宽度比较大的第一压腿522a可起到定位和对准的作用。替代地，压腿522可形成一个可与插件53的第二端539b端面匹配的筒状结构，并且在该筒状结构的侧壁上设置可与辅助出水口147对齐的大的开口，以允许微气泡水从微气泡水室515流入辅助出水口147。从板状本体521的内侧面521a上围绕压腿522的外周延伸出可包裹插件53外周的插件引导边525。在气泡发生器5的组装状态下，该插件引导边525起引导作用，同时使得插件在插件室内的安装更加牢固。
上述气泡发生器5在工作时，来自外部水源的水从进水端111进入进水部511，沿着水流方向C，水流在经过加压通道112加压后通过节流孔513膨胀喷入负压腔531并且在负压腔内产生负压。在负压的作用下，大量外界空气从吸气槽143经由进气口145和进气通道516通过缺口392被吸入负压腔531。然后，空气与水流一起流入混合腔532并且在其中得到更加充分的混合以产生气泡水。气泡水然后流向微气泡起泡器54并且被该微气泡起泡器54切割和进一步混合，形成含有大量微气泡的微气泡水。该微气泡水从微气泡水室515经由压板52上的微气泡水出口526喷出。从溢流口535溢出的水和/或从压腿522之间的周向间隙523流出的微气泡水可经由辅助出水口147流出。
本发明还提供一种洗涤设备，该洗涤设备包括本发明气泡发生器5。该气泡发生器5布置在该洗涤设备内以提供微气泡水。通过该气泡发生器，不仅能够提高洗涤设备的洗净能力，而且能够减少洗涤处理剂的用量并降低洗涤处理剂在例如衣物中的残留量，从而不仅有利于用户的健康，而且还能改善用户的体验。
图14是本发明洗涤设备的一种实施例的结构示意图。在该实施例中，洗涤设备为一种波轮洗衣机1。替代地，在其它实施例中，洗涤设备可以是滚筒洗衣机或烘干一体机等。
如图14所示，波轮洗衣机1(以下简称洗衣机)包括箱体11。在箱体11的底部设有地脚14。箱体11的上部设置有盘座12，盘座12枢转连接有上盖13。在箱体11内设置有洗涤筒10，洗涤筒10包括作为盛水桶的外桶21。在外桶21内设置有内桶31，内桶31的底部设置有波轮32，外桶21的下部固定有电机34，电机34通过传动轴33与波轮32驱动连接，在内桶31的侧壁上设有脱水孔311。排水阀41设置在排水管42上，排水管42的上游端与外桶21的底部连通。该洗衣机还包括进水阀61、一端连接进水阀61的进水管62、连接进水管62的另一端的气泡发生器5、以及连接进水管62和气泡发生器5的连接机构17。气泡发生器5被安装在盘座12上。气泡发生器5可以是上面所描述的任一种气泡发生器。
图15是本发明洗涤设备的连接机构的实施例的第一立体示意图；图16是本发明洗涤设备的连接机构的实施例的第二立体示意图。如图15和16所示，在一种或多种实施例中，连接机构17包括连接套71、卡座72、和固定件73。连接套71大致为圆柱套筒结构，在连接套71的一端的内壁上向内突出形成连接凸块711，在连接套的另一端的内壁形成卡爪槽712。卡座72包括圆环盘722和沿着垂直于圆环盘722的方向从圆环盘722的内侧面(朝向连接套71)向外延伸的多个卡爪721。多个卡爪721沿周向分布，例如设置4个卡爪721。卡座72通过卡爪721与连接套71的卡爪槽712形成连接。在连接机构17的组装状态下，卡座72的圆环盘722与连接套71端面之间留有安装固定件73的轴向空间。固定件73为大致月牙形的结构，可卡在卡爪721的外周上，并且其两端分别抵靠圆环盘722端面和连接套71端面。替代地，固定件73也可以设置成开口环状结构。在固定件73大致中间位置沿着固定件73外周并沿固定件73的中心线方向往外延伸出弧形凸起731。在弧形凸起731的顶部开设有可与箱体11配合连接的弧形凹槽732。在连接机构17的组装状态下，弧形凸起731位于圆环盘722的上方位置。替代地，也可以取消弧形凸起731。
如图3所示，在一种或多种实施例中，连接机构17通过套在进水管62外侧的卡座72与进水管62连接，并且通过连接凸块711与进水端111上的连接套槽111a连接。进水管62穿过进水端111伸入直通道113内，进水管62外侧套有两个进水管密封圈18，由于进水端111的孔径(略小于进水密封圈18 的外径)大于直通道113的孔径(略大于进水管的外径)，因此进水管密封圈18被卡在进水端111与直通道113交界处。因此，在进水端111内壁与进水管的外壁之间形成流体密封。替代地，在进水管62外侧设有一个或者多个进水管密封圈18。通过设在直通道113和加压通道112内壁上的四条管道加强筋114可以更好的将进水管62定位在通道的中心位置上，防止进水管62偏向一侧，影响进水效果。进水管62可伸入的末端位置可由进水管限位条115限制在直通道113内，防止安装时操作失误，将进水管伸入太深造成加压通道112的损坏。
如图14所示，在一种或多种实施例中，来自水源(例如自来水或可循环使用的水)的水经由进水阀61和进水管62进入气泡发生器5，并且通过气泡发生器5产生微气泡水。所产生的微气泡水主要从压板52上的微气泡水出口喷出到盘座12的内翻边，该内翻边可起到挡水的作用，使得微气泡水被改向流入内桶31和/或外桶21，用于衣物等的清洗。来自插件53的溢流口535的水和从压腿522之间喷溅出的水则从辅助出水口147流出，然后也进入内桶31和/或外桶21。水中的微气泡在破碎过程中对洗涤处理剂产生撞击，并且微气泡通过携带的负电荷也能够吸附洗涤处理剂，因此微气泡能够增加洗涤处理剂与水的混合程度，从而降低洗涤处理剂的用量并减少洗涤处理剂在衣物上的残留量。另外，微气泡在内桶31内也会撞击衣物上的污渍，并且会吸附产生污渍的异物。因此，微气泡增强了洗衣机的去污性能。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对来自不同实施例的技术特征进行组合，也可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
