Definitions

  • the invention relates to washing equipment, in particular to a microbubble spray head, a microbubble treatment agent box assembly and a washing equipment having the microbubble treatment agent box assembly.
  • Micro-bubble generally refers to tiny bubbles with a diameter of less than fifty microns ( ⁇ m) when the bubbles occur.
  • Micro-bubbles can also be called micro-/nano-bubble, micro-bubble or nano-bubble according to their diameter range. Because of its low buoyancy in the liquid, the microbubbles stay in the liquid for a long time. Moreover, the microbubbles will shrink in the liquid until they finally break, generating smaller nanobubbles. In this process, the bubble's rising speed becomes slow because it becomes smaller, resulting in high melting efficiency. When the microbubbles are broken, high pressure and high temperature heat are generated locally, which can destroy foreign objects such as organic matter floating in the liquid or attached to the object.
  • microbubbles have strong cleaning and purification capabilities.
  • microbubbles have been widely used in washing machines such as washing machines.

  • the agent box is mixed with the detergent or softener in the washing treatment agent box and then enters the washing tub to be used for washing clothes.
  • this kind of fine bubble generator can only generate fine bubbles by relying on the very limited air carried inside the liquid flowing through it. Therefore, the fine bubble generator cannot provide the washing treatment cartridge with microbubbles containing enough microbubbles. Bubble water affects the dissolution of detergent and/or softener, resulting in poor cleaning effect, and residual detergent may cause hidden dangers to the health of users.

技术领域
本发明涉及洗涤设备，具体地涉及微气泡喷头、微气泡处理剂盒组件及具有该微气泡处理剂盒组件的洗涤设备。
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，中国公开专利申请CN108625120A公开了一种洗衣机，该洗衣机具有供水机构部(相当于洗涤剂盒组件)，并且在供水机构部中设有洗涤处理剂盒(容纳粉末、液体洗涤剂和柔顺剂)和用于向洗涤处理剂盒提供微气泡水以溶解洗涤处理剂的细微气泡产生器。具体地，CN108625120A公开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一级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，然后微气泡水流入洗涤处理剂盒并与洗涤处理剂盒中的洗涤剂或柔顺剂等混合后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非常有限的空气来产生细微气泡，因此，该细微气泡产生器不能为洗涤处理剂盒提供含有足够多微气泡的微气泡水，从而影响对洗涤剂和/或柔顺剂的溶解，进而导致洗净效果不好，残留的洗涤剂可能对用户的健康产生隐患。
相应地，本领域需要一种新的技术方案来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有微气泡喷头的微气泡产生效率不高的技术问题，本发明提供了一种微气泡喷头。所述微气泡喷头包括喷管和固定在所述喷管的出口端上的微气泡起泡器，在所述喷管内设有直径变小锥形通道部和混合腔，在所述 直径变小锥形通道部内沿着水流方向具有至少一级直径变小锥形通道，在所述直径变小锥形通道部的下游端上设有节流孔并且所述节流孔的直径小于所述混合腔的直径，以便水流通过所述节流孔喷入所述混合腔并且在所述混合腔中产生负压；并且在所述喷管的出口端和所述微气泡起泡器上分别设有相互连通的吸气口，使得空气能够借助所述负压经由所述吸气口被吸入所述混合腔并与所述水流混合形成气泡水，所述气泡水通过所述微气泡起泡器被切割和混合而形成微气泡水。
在上述微气泡喷头的优选技术方案中，所述混合腔的直径沿着所述水流方向保持不变或者逐渐增大。
在上述微气泡喷头的优选技术方案中，在所述直径变小锥形通道部内设置有扰流部。
在上述微气泡喷头的优选技术方案中，所述吸气口也是所述微气泡喷头的溢流口。
在上述微气泡喷头的优选技术方案中，所述微气泡起泡器包括多层滤网和固定所述多层滤网的网架。
在上述微气泡喷头的优选技术方案中，围绕所述喷管的出口端的外壁上设有多个卡爪，并且围绕所述网架的靠近所述出口端的轴向端上设有多个卡口以分别容纳所述多个卡爪中的一个。
在上述微气泡喷头的优选技术方案中，所述微气泡起泡器还包括压环，所述压环被置于所述出口端的端面与所述网架之间以将所述多层滤网抵靠在所述网架上。
在上述微气泡喷头的优选技术方案中，在所述压环的两个轴向端面上分别形成有沿轴向向外延伸的多个彼此间隔开的凸起以在相邻的所述凸起之间形成凹槽。
本领域技术人员能够理解的是，在本发明的技术方案中，微气泡喷头包括喷管和固定在喷管的出口端上的微气泡起泡器。在喷管内设有直径变小锥形通道部和混合腔。在直径变小锥形通道部内沿着水流方向具有至少一级直径变小锥形通道，并且在直径变小锥形通道部的下游端上设有节流孔。该至少一级直径变小锥形通道能够对流过其中的水流进行加压。节流孔的直径远小于混合腔的直径，因此被加压后的水流通过节流孔能够快速膨胀地喷入混合腔并且在混合腔中产生负压。在喷管的出口端和微气泡起泡器上分别设有相互连通的吸气口，这些吸气口配置成使得外界的空气能够借助负压经由这些吸气口被大量地吸入混合腔并与混合腔中的水流混合形成气泡水。产生的气泡水然后被微气泡起泡器切割和混合而形成具有大量微气泡的微气泡水。因此，本发明的微气泡喷头显著提高了微气泡产生的效率。
优选地，混合腔的直径相对于节流孔的直径突然增大后保持不变，或者继续逐渐增大，从而有助于增加空气与水流的混合程度。
优选地，在直径变小锥形通道部的内壁上设置的扰流部通过加大水的紊流能够帮助水流在下游更加有效地混合被吸入的空气。
优选地，吸气口在需要时也能够充当微气泡喷头的溢流口。当喷管内的水压不足，因此水流无法快速贯穿微气泡起泡器中的滤网时，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吸气口进而导致无法吸气的问题，从而保证微气泡喷头持续产生微气泡水的高可靠性。
优选地，微气泡起泡器包括的多层滤网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。通过网架固定多层滤网，能够避免滤网在高水压的冲击下从喷管上脱落的问题。
优选地，通过喷管的出口端上的多个卡爪和网架上的多个卡口的相互配合，能够实现喷管和微气泡起泡器通过卡接结构固定在一起。
优选地，位于喷管的出口端与网架之间的压环将多层滤网抵靠在网架上，以进一步牢固地固定滤网。在压环的两个轴向端面上的多个凸起之间分别形成了凹槽，这些凹槽能够帮助从外界吸入空气，从而进一步保证吸气的可靠性。

第一实施方式
为了解决现有微气泡产生器的微气泡产生率不高的技术问题，本发明提供一种微气泡喷头52。该微气泡喷头52包括喷管521和固定在喷管521的出口端214上的微气泡起泡器522。在喷管521内设有直径变小锥形通道部216和混合腔219。在直径变小锥形通道部216内沿着水流方向C具有至少一级直径变小锥形通道。在直径变小锥形通道部216的下游端上设有节流孔218并且节流孔218的直径小于混合腔219的直径，以便水流通过节流孔218喷入混合腔219并且在混合腔219中产生负压。在喷管521的出口端214和微气泡起泡器522上分别设有相互连通的吸气口215、222，使得空气能够借助负压经由吸气口215、222被吸入混合腔219并与水流混合形成气泡水。气泡水通过微气泡起泡器522被切割和混合而形成微气泡水。
在本文中所说的“直径变小锥形通道部”是指形成在该部分内部的通道直径或垂直于水流方向的横截面逐渐变小从而使该通道大致呈锥形的结构。
图1是本发明微气泡喷头的实施例的俯视图，图2是图1所示的本发明微气泡喷头的实施例的前视图，以及图3是图1所示的本发明微气泡喷头的实施例的立体分解图。如图1-图3所示，在一种或多种实施例种，喷管521为一体式喷管，大致呈筒状。喷管521具有进口端211和出口端214。进口端211用于连接到外部的水源，例如自来水；出口端214上固定有微气泡起泡器522。因此，水流能够从进口端211流入喷管521，再从出口端214经由微气泡起泡器522流出喷管521。
在喷管521的外壁上可设置定位部212，用于将微气泡喷头52定位在合适的位置上。参见图1和图3，在一种或多种实施例中，定位部212可以是沿喷管521的轴向在进口端211和出口端214之间延伸或部分延伸的纵向肋。替代地，定位部212也能够采用其它合适的形式，例如柱状突起或凹槽。
参见图1和图3，在一种或多种实施例中，在喷管521的出口端214的外壁上设有多个卡爪213，例如两个、三个、或更多个，用于将微气泡起泡器522与喷管521固定在一起。可选地，卡爪213沿着出口端214的外壁周向地分布并且径向向外延伸，彼此之间间隔相同或不相同的距离。继续参照图3，在喷管521的出口端214上还设有多个吸气口215，例如两个、三个、或更多个。这些吸气口215沿着出口端214的周向分布，彼此之间间隔相同或不相同的距离。如图3所示，在一种或多种实施例中，每个吸气口215都是自出口端214的出口端面214a沿着喷管521的轴向向进口端211方向凹入的大致矩形的缺口。替代地，吸气口215也可以是设置在出口端214的管壁上的通孔，例如圆形孔。
如图2和图3所示，在一种或多种实施例中，微气泡起泡器522包括滤网224和将滤网224固定在喷管521的出口端214上的网架221。如图3所示，在一种或多种实施例中，网架221为两端开口并且呈大致圆筒状。网架221具有第一轴向端221a和第二轴向端221b。第一轴向端221a被配置成可抵接滤网224，而第二轴向端221b被配置成能够套在喷管521的出口端214 的外壁上，因此在微气泡起泡器522与喷管521组装好的状态下，滤网224被牢固地夹在网架221的第一轴向端221a与喷管521的出口端面214a之间。
参见图3，在一种或多种实施例中，在网架221的第二轴向端221b上设有多个吸气口222和多个卡口223。吸气口222和卡口223都是沿着第二轴向端221b的周向布置。吸气口222之间、卡口223之间以及吸气口222和卡口223之间均间隔相同或不相同的距离。当微气泡起泡器522与喷管521组装好后，网架221上的每个吸气口222都分别对应喷管521的出口端214上的一个吸气口215，使得对应的吸气口222、215不仅相互连通，而且还连通混合腔219，从而允许外界的空气能够通过这些吸气口222、215被吸入到喷管521的混合腔219中。还需要指出的是，这些吸气口222、215同时还能充当溢流口。如果喷管521内的水压不足，水流就可能无法快速贯穿微气泡起泡器522中的滤网，因此会累积在喷管521的混合腔219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吸气口进而导致无法吸气的情形，从而保证微气泡喷头持续产生微气泡水的高可靠性。进一步地，当微气泡起泡器522与喷管521组装好后，网架221上的每一个卡口223都接纳位于喷管521的出口端214上的对应的一个卡爪213，从而将微气泡起泡522与喷管521固定在一起。替代地，微气泡起泡器522与喷管521也能够利用其它连接方法固定在一起，例如焊接方式、螺纹连接方式等。
如图3所示，在一种或多种实施例中，滤网224包括多层滤网，例如两层、三层或更多层。滤网为网孔结构，该网孔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，滤网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。
继续参见图3，在一种或多种实施例中，微气泡起泡器522还包括压环225。压环225为大致圆环状。压环225具有第一轴向端面225a和第二轴向端面225b。可选地，在一种或多种实施例中，在第一轴向端面225a和第二轴向端面225b上沿周向均设有多个凸起251。这些凸起251相互间隔预定距离并且从各自对应的端面沿着轴向向外延伸，因此在每个轴向端面225a、225b上的每两个凸起251之间都形成有凹槽252。在组装状态下，第一轴向端面225a朝向滤网224和网架221并且第一轴向端面225a上的凸起251将滤网224牢固地抵靠在位于网架221的第一轴向端221a内的径向向内延伸的台阶221c(参见图4)上；第二轴向端面225b朝向喷管521的出口端面214a，并且第二轴向端面225b上的凸起251抵靠在喷管521的出口端面214a上。位于凸起251之间的凹槽252连通混合腔219，因此也能充当吸气口，通过允许从这些凹槽252吸入外界的空气，从而进一步提高喷管进气的可靠性。
图4是沿着图1的剖面线A-A截取的本发明微气泡喷头实施例的剖面图。如图4所示，在一种或多种实施例中，在喷管521的直径变小锥形通道部216的内部沿着水流方向c形成有第一级直径变小锥形通道216a和第二级直径变小锥形通道216b。替代地，在直径变小锥形通道部216内沿着水流方向可以形成一级或多于两级的直径变小锥形通道。第一级直径变小锥形通道216a从喷管521的进口端211延伸到第二级直径变小锥形通道216b。第一级直径变小锥形通道216a的最小直径可大于第二级直径变小锥形通道216b的最大直径。第二级直径变小锥形通道216b沿着水流方向C继续向下游延伸到位于直径变小锥形通道部216的下游端上的节流孔218。节流孔218的直径小于或等于第二级直径变小锥形通道216b的最小直径。位于节流孔 218下游的混合腔219的直径远大于节流孔218的直径。可选地，混合腔219的直径沿着水流方向C可以保持不变，或者混合腔219的直径沿着水流方向C逐渐增大以增加空气与水的混合程度。
水流从进口端211流入喷管521后先流过第一级直径变小锥形通道216a和第二级直径变小锥形通道216b以在其中经受加压。加压后的水流通过节流孔218被迅速膨胀地喷出到下游的混合腔219中并且在混合腔219内产生负压。因此，在负压的作用下，外界空气通过吸气口215、222和/或252被吸入到混合腔219中并且与混合腔219中的水流混合以产生气泡水。气泡水然后流过微气泡起泡器522的滤网224而被切割和混合，从而产生含有大量微气泡的微气泡水。
如图4所示，在一种或多种实施例中，在第二级直径变小锥形通道216b的内壁上设有多条沿着纵向延伸的扰流筋217，这些扰流筋217彼此间隔开，以增加水流的紊流，从而能够帮助水流在下游更加有效地混合被吸入的空气。替代地，扰流筋可以被设在该级直径变小锥形通道的内壁上的至少一个径向突起部取代，例如一个或多个的柱状突起。替代地，扰流筋或其它形式的扰流部可以形成在每一级直径变小锥形通道的内壁上。
继续参照图4，在一种或多种实施例中，直径变小锥形通道部216的对应第二级直径变小锥形通道216b的部分与喷管521的内壁分离，因此在该部分与喷管521的对应内壁之间形成了环形腔300。该环形腔300与混合腔219连通成一体，有助于进一步增强空气与水流的混合。
图5是本发明微气泡处理剂盒组件的实施例的俯视图，并且图6是沿着图5的剖面线B-B截取的本发明微气泡处理剂盒组件的实施例的剖面图。如图5和图6所示，本发明还提供了一种微气泡处理剂盒组件53。该微气泡处理剂组件53包括洗涤处理剂盒531和布置在洗涤处理剂盒531上的微气泡喷头52。在一种或多种实施例中，洗涤处理剂盒531能够用于容纳的洗涤处理剂包括但不限于粉末洗涤剂、固态洗涤剂、或液体洗涤剂。洗涤处理剂盒531上设有进水口和出水口532，其中，进水口由微气泡喷头52提供。
如图6所示，在一种或多种实施例中，微气泡喷头52定位在洗涤处理剂盒531的一个侧壁的上部，而出水口532定位在洗涤处理剂盒531的另一个侧壁的底部。如图5所示，微气泡喷头52所处的侧壁与出水口532所处的侧壁彼此相对。外部水源能够通过微气泡喷头52的进口端211经由微气泡喷头52被喷入洗涤处理剂盒531中，以用微气泡水溶解容纳在洗涤处理剂盒531中的洗涤处理剂。微气泡喷头52可以是在上面所描述的任一种微气泡喷头。溶解了洗涤处理剂的微气泡水混合物从出水口532排出，例如被提供给洗涤设备。相比于现有技术的带有微气泡发生器的微气泡处理剂盒组件，本发明微气泡处理剂盒组件产生微气泡的能力被极大地提高，从而提高了洗涤处理剂在水中的溶解速度、溶解率和混合程度，进而能够节省洗涤处理剂的用量。
第二实施方式
为了解决现有微气泡处理剂盒组件对洗涤处理剂的溶解效率不高的技术问题，本发明提供了一种微气泡处理剂盒组件53。在第二实施方式中，微气泡处理剂盒组件53包括洗涤处理剂盒531和布置在洗涤处理剂盒531上的微气泡喷头52。微气泡喷头52形成为洗涤处理剂盒531的进水口并且为洗涤处理剂盒531提供微气泡水。微气泡喷头52包括喷管521和固定在喷管521的出口端214上的微气泡起泡器522。在喷管521内设有直径变小锥形通道部216和混合腔219。在直径变小锥形通道部216内沿着水流方向C具有至少一级直径变小锥形通道。在直径变小锥形通道部216的下游端上设有节流孔218并且节流孔218的直径小于混合腔219的直径，以便水流通过节流孔218喷入混合腔219并且在混合腔219中产生负压。在喷管521的出口端214和微气泡起泡器522上分别设有可相互连通的吸气口215、222，使得空气能够借助负压 经由吸气口215、222被吸入混合腔219并与水流混合形成气泡水。气泡水通过微气泡起泡器522被切割和混合而形成微气泡水。
在本文中所说的"直径变小锥形通道部"是指形成在该部分内部的通道直径或垂直于水流方向的横截面逐渐变小从而使该通道大致呈锥形的结构。
图7是本发明微气泡处理剂盒组件在第二实施方式中的实施例的俯视图，并且图8是沿着图7的剖面线A-A截取的本发明微气泡处理剂盒组件在第二实施方式中的实施例的剖面图。如图7和图8所示，在一种或多种实施例中，洗涤处理剂盒531包括壳体531a，形成在该壳体531a内的洗涤处理剂室531c和围绕洗涤处理剂室531c的环形室531b。洗涤处理剂室531c与环形室531b形成流体连通。微气泡喷头52被布置在壳体531a的一个侧壁的上部并且延伸进入洗涤处理剂室531c以将微气泡水喷在洗涤处理剂室531c中。在壳体531a上还设有出水口532，该出水口532与环形室531b形成流体连通。出水口532被设置在壳体531a的另一个侧壁上并且靠近该侧壁的底部。如图7所示，出水口532所处的侧壁与微气泡喷头52所处的侧壁相对。替代地，微气泡喷头52和出水口532的位置可以根据实际需要进行调整。
洗涤处理剂室531c能够用于容纳不同的洗涤处理剂，包括但不限于粉末洗涤剂、固态洗涤剂、液体洗涤剂、或柔顺剂。如图7和图8所示，在一种或多种实施例中，在洗涤处理剂室531c中设有虹吸结构。可选地，该虹吸结构包括虹吸管533和虹吸帽(图中未示出)。如图8所示，在一种或多种实施例中，虹吸管533从洗涤处理剂室531c的底部竖直地向上延伸，并且虹吸管533的高度低于微气泡喷头52的最低水平位置高度。因此，在洗涤处理剂室531c内的液面较高时，虹吸管533和虹吸帽相互配合产生虹吸效应以将洗涤处理剂室531c中的例如洗涤处理剂与水的混合液排出。
当处于操作状态中时，外部水源首先通过微气泡喷头52的进口端211进入微气泡喷头52，并且通过微气泡喷头52的微气泡起泡器522生成微气泡水。该微气泡水然后被喷入洗涤处理剂室531c中，以用微气泡水溶解容纳在该洗涤处理剂室531c中的洗涤处理剂。溶解和混合了洗涤处理剂的水流通过虹吸结构被排到环形室531b中和/或通过溢流进入环形室531b中，然后通过出水口532流出洗涤处理剂盒531并进入洗涤设备的外筒或外桶。本发明微气泡处理剂盒组件通过增强微气泡喷头52的微气泡产生能力来提高洗涤处理剂在水中的溶解速度、溶解率和混合程度，进而能够节省洗涤处理剂的用量。
图1是本发明微气泡处理剂盒组件在第二实施方式中的微气泡喷头的实施例的俯视图，图2是图1所示的本发明微气泡处理剂盒组件在第二实施方式中的微气泡喷头的实施例的前视图，以及图3是图1所示的本发明微气泡处理剂盒组件在第二实施方式中的微气泡喷头的实施例的立体分解图。本发明微气泡处理剂盒组件在第二实施方式中使用的微气泡喷头同上述第一实施方式中的微气泡喷头。如图1-图3所示，在一种或多种实施例种，喷管521为一体式喷管，大致呈筒状。喷管521具有进口端211和出口端214。进口端211用于连接到外部的水源，例如自来水；出口端214上固定有微气泡起泡器522。因此，水流能够从进口端211流入喷管521，再从出口端214经由微气泡起泡器522流出喷管521。
在喷管521的外壁上可设置定位部212，用于将微气泡喷头52定位在合适的位置上。参见图1和图3，在一种或多种实施例中，定位部212可以是沿喷管521的轴向在进口端211和出口端214之间延伸或部分延伸的纵向肋。替代地，定位部212也能够采用其它合适的形式，例如柱状突起或凹槽。
参见图1和图3，在一种或多种实施例中，在喷管521的出口端214的外壁上设有多个卡爪213，例如两个、三个、或更多个，用于将微气泡起泡器522与喷管521固定在一起。可选地，卡爪213沿着出口端214的外壁周向地分布并且径向向外延伸，彼此之间间隔相同或不相同的距离。继续参照图3，在喷管521的出口端214上还设有多个吸气口215，例如两个、 三个、或更多个。这些吸气口215沿着出口端214的周向分布，彼此之间间隔相同或不相同的距离。如图3所示，在一种或多种实施例中，每个吸气口215都是自出口端214的出口端面214a沿着喷管521的轴向向进口端211方向凹入的大致矩形的缺口。替代地，吸气口215也可以是设置在出口端214的管壁上的通孔，例如圆形孔。
如图2和图3所示，在一种或多种实施例中，微气泡起泡器522包括滤网224和将滤网224固定在喷管521的出口端214上的网架221。如图3所示，在一种或多种实施例中，网架221为两端开口并且呈大致圆筒状。网架221具有第一轴向端221a和第二轴向端221b。第一轴向端221a被配置成可抵接滤网224，而第二轴向端221b被配置成能够套在喷管521的出口端214的外壁上，因此在微气泡起泡器522与喷管521组装好的状态下，滤网224被牢固地夹在网架221的第一轴向端221a与喷管521的出口端面214a之间。
参见图3，在一种或多种实施例中，在网架221的第二轴向端221b上设有多个吸气口222和多个卡口223。吸气口222和卡口223都是沿着第二轴向端221b的周向布置。吸气口222之间、卡口223之间以及吸气口222和卡口223之间均间隔相同或不相同的距离。当微气泡起泡器522与喷管521组装好后，网架221上的每个吸气口222都分别对应喷管521的出口端214上的一个吸气口215，使得对应的吸气口222、215不仅相互连通，而且还连通混合腔219，从而允许外界的空气能够通过这些吸气口222、215被吸入到喷管521的混合腔219中。还需要指出的是，这些吸气口222、215同时还能充当溢流口。如果喷管521内的水压不足，水流就可能无法快速贯穿微气泡起泡器522中的滤网，因此会累积在喷管521的混合腔219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吸气口进而导致无法吸气的情形，从而保证微气泡喷头持续产生微气泡水的高可靠性。进一步地，当微气泡起泡器522与喷管521组装好后，网架221上的每一个卡口223都接纳位于喷管521的出口端214上的对应的一个卡爪213，从而将微气泡起泡522与喷管521固定在一起。替代地，微气泡起泡器522与喷管521也能够利用其它连接方法固定在一起，例如焊接方式、螺纹连接方式等。
如图3所示，在一种或多种实施例中，滤网224包括多层滤网，例如两层、三层或更多层。滤网为网孔结构，该网孔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，滤网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。
继续参见图3，在一种或多种实施例中，微气泡起泡器522还包括压环225。压环225为大致圆环状。压环225具有第一轴向端面225a和第二轴向端面225b。可选地，在一种或多种实施例中，在第一轴向端面225a和第二轴向端面225b上沿周向均设有多个凸起251。这些凸起251相互间隔预定距离并且从各自对应的端面沿着轴向向外延伸，因此在每个轴向端面225a、225b上的每两个凸起251之间都形成有凹槽252。在组装状态下，第一轴向端面225a朝向滤网224和网架221并且第一轴向端面225a上的凸起251将滤网224牢固地抵靠在位于网架221的第一轴向端221a内的径向向内延伸的台阶221c(参见图4)上。第二轴向端面225b朝向喷管521的出口端面214a，并且第二轴向端面225b上的凸起251抵靠在喷管521的出口端面214a上。位于凸起251之间的凹槽252连通混合腔219，因此也能充当吸气口，通过允许从这些凹槽252吸入外界的空气，从而进一步提高喷管进气的可靠性。
图4是沿着图3的剖面线B-B截取的本发明微气泡处理剂盒组件的微气泡喷头实施例的剖面图。如图4所示，在一种或多种实施例中，在喷管521的直径变小锥形通道部216的内部沿着水流方向c形成有第一级直径变小锥形通道216a和第二级直径变小锥形通道216b。替代地，在直径变小锥形通道部216内沿着水流方向可以形成一级或多于两级的直径变小锥形通道。第一级直径变小锥形通道216a从喷管521的进口端211延伸到第二级直径变小锥形通道216b。第一级直径变小锥形通道216a的最小直径可大于第二级直径变小锥形通道216b的最大直径。第二级直径变小锥形通道216b沿着水流方向C继续向下游延伸到位于直径变小锥形通道部216的下游端上的节流孔218。节流孔218的直径小于或等于第二级直径变小锥形通道216b的最小直径。位于节流孔218下游的混合腔219的直径远大于节流孔218的直径。可选地，混合腔219的直径沿着水流方向C可以保持不变，或者混合腔219的直径沿着水流方向C逐渐增大以增加空气与水的混合程度。
水流从进口端211流入喷管521后先流过第一级直径变小锥形通道216a和第二级直径变小锥形通道216b以在其中经受加压。加压后的水流通过节流孔218被迅速膨胀地喷出到下游的混合腔219中并且在混合腔219内产生负压。因此，在负压的作用下，外界空气通过吸气口215、222和/或252被吸入到混合腔219中并且与混合腔219中的水流混合以产生气泡水。气泡水然后流过微气泡起泡器522的滤网224而被切割和混合，从而产生含有大量微气泡的微气泡水。
如图4所示，在一种或多种实施例中，在第二级直径变小锥形通道216b的内壁上设有多条沿着纵向延伸的扰流筋217，这些扰流筋217彼此间隔开，以增加水流的紊流，从而能够帮助水流在下游更加有效地混合被吸入的空气。替代地，扰流筋可以被设在该级直径变小锥形通道的内壁上的至少一个径向突起部取代，例如一个或多个的柱状突起。替代地，扰流筋或其它形式的扰流部可以形成在每一级直径变小锥形通道的内壁上。
继续参照图4，在一种或多种实施例中，直径变小锥形通道部216的对应第二级直径变小锥形通道216b的部分与喷管521的内壁分离，因此在该部分与喷管521的对应内壁之间形成了环形腔300。该环形腔300与混合腔219连通成一体，有助于进一步增强空气与水流的混合。
本发明还提供一种洗涤设备，该洗涤设备包括本发明的第一和第二实施方式中的任一种微气泡处理剂盒组件53。该微气泡处理剂盒组件53设置成在该洗涤设备内以提供洗涤处理剂微气泡水混合物。通过该微气泡处理剂盒组件，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。
参照图9，图9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9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的侧壁上靠近顶端设有脱水孔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51、与进水阀51连通的微气泡喷头52和结合该微气泡喷头52的微气泡处理剂盒组件53，微气泡处理剂盒组件53被安装在外桶21的顶部上方。微气泡喷头52可以是上面所描述的任一种微气泡喷头。水经由进水阀51先进入微气泡喷头52以产生微气泡水，微气泡水然后进入微气泡处理剂盒组件53以利用微气泡水来快速溶解洗涤处理剂盒中的洗涤处理剂，例如粉 末洗涤剂、固态洗涤剂或液体洗涤剂。微气泡处理剂盒组件53然后将洗涤处理剂微气泡水混合物提供给外桶21，用于衣物清洗。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，微气泡还增强了洗衣机的去污性能。
参照图10，图10是本发明洗涤设备的另一种实施例的结构示意图。在该实施例中，洗涤设备为一种滚筒洗衣机9。
如图10所示，滚筒洗衣机9包括外壳91和位于外壳底部的地脚98。在外壳91的顶部设有上台面板94。外壳91的前侧(面对用户的操作侧)上设有允许用户向滚筒洗衣机内装填衣物等的门体97，而门体97上还设有能够看到洗衣机内部的观察窗96。在观察窗96与外壳91之间还设置密封窗垫961，并且该密封窗垫961固定在外壳91上。滚筒洗衣机9的控制面板95布置在外壳91的前侧的上部，以便于用户的操作。在外壳91的内部则布置有外筒92和内筒93。内筒93定位在外筒92的内部。内筒93通过传动轴932和轴承933连接到电机931(例如直驱电机)。在外壳91的后侧的上部上设有进水阀51，该进水阀51通过水管连通微气泡喷头52，而该微气泡喷头52被结合在微气泡处理剂盒组件53中以向洗涤处理剂盒提供微气泡水。该微气泡喷头52可以是上面所描述的任一种微气泡喷头。如图10所示，微气泡处理剂盒组件53定位位于上台面板94的下方并且位于外筒92的上方。类似于上述实施例，水经由进水阀51通过水管进入微气泡喷头52并且通过微气泡喷头52变成微气泡水。该微气泡水然后被喷入微气泡处理剂盒组件53以利用微气泡水来快速溶解洗涤处理剂盒中的洗涤处理剂，例如粉末洗涤剂、固态洗涤剂或液体洗涤剂。微气泡处理剂盒组件53然后将洗涤处理剂微气泡水混合物提供给外筒92，用于衣物清洗。
第三实施方式
为了解决现有注水盒的微气泡产生率不高的技术问题，本发明提供了一种微气泡处理剂盒组件52。在第三实施方式中，该微气泡处理剂盒组件包括壳体521和容纳在壳体521内的处理剂盒522。在壳体521上设有微气泡进水管部527、直径变小锥形通道部272、进气通道275和微气泡起泡器274。在直径变小锥形通道部272内沿着水流方向c设有至少一级直径变小锥形通道，并且在直径变小锥形通道部272的下游端上设有喷孔273。直径变小锥形通道部272定位成使得进入微气泡进水管部527的水流将在至少一级直径变小锥形通道内经受加压并且从喷孔273膨胀地喷出以在喷孔273附近产生负压。进气通道275定位靠近喷孔273，使得外界空气借助负压通过进气通道275被吸入并与喷出后的水流混合形成气泡水。气泡水流过微气泡起泡器274以形成微气泡水并且被喷到所述处理剂盒522中。因此，相比于现有技术的带有微气泡发生器的注水盒，本发明微气泡处理剂盒组件产生微气泡的能力被极大地提高，从而提高了处理剂在水中的溶解速度、溶解率和混合程度，进而能够节省处理剂的用量。
在本文中所说的"直径变小锥形通道部"是指形成在该部分内部的通道直径或垂直于水流方向的横截面逐渐变小从而使该通道大致呈锥形的结构。
图11是本发明微气泡处理剂盒组件的实施例的立体示意图，图12是图11所示的本发明微气泡处理剂盒组件的实施例的正视图，而图13是图11所示的本发明微气泡处理剂盒组件的实施例的俯视图。
参照图11-13，在一个或多个实施例中，微气泡处理剂盒组件52包括壳体521和处理剂盒522。处理剂盒522能够被容纳在壳体521内，并且在壳体521内是可移动的以便被抽拉进出该壳体521。在本文中，处理剂包括洗涤剂、一种或多种衣物护理剂等，衣物护理剂例如可以是柔顺剂，除菌液等。
如图11-13所示，在一个或多个实施例中，壳体521上设有主进水管部525、柔顺剂进水管部526、和微气泡进水管部527。主进水管部525、柔顺剂进水管部526和微气泡进水管部527都布置在壳体521的顶部上，并且分布在顶部的两侧，其中，微气泡进水管部527和柔顺剂进水管部526位于壳体521的同一侧上。主进水管部525和柔顺剂进水管部526均可以连接到外部的水源，并且分别为处理剂盒522中的洗涤剂室221和护理剂室222提供非微气泡水，例如自来水或井水或其它水源，因此二者都属于非微气泡进水管部。微气泡进水管部527则配置成为处理剂盒522提供微气泡水。相对于处理剂盒522的抽拉方向，在壳体521的左右两侧上分别设有两个对称的第一固定部523和两个对称的第二固定部524。第一固定部523和第二固定部524用于将微气泡处理剂盒组件52固定到例如洗涤设备上，例如通过螺钉连接或焊接连接。在替代的实施例中，根据需要，除了微气泡进水管部527之外，在壳体521上能够只设置一个非微气泡进水管部，例如主进水管部525，或者也能够设置多于两个的非微气泡进水管部。
图14是沿着图13的剖面线A-A截取的本发明微气泡处理剂盒组件52在第三实施方式中的第一实施例的剖视图。如图14所示，在一种或多种实施例中，处理剂盒522具有并列布置的洗涤剂室221和护理剂室222。洗涤剂室221设置成用于容纳洗涤剂。护理剂室222设置成用于容纳柔顺剂。在替代的实施例中，在处理剂盒522中能够只设置一个用于容纳例如洗涤剂的腔室。在替代的实施例中，在处理剂盒522中能够设置多个腔室，例如在这些腔室中包括两个或更多个护理剂室，分别用于容纳不同的护理剂。在一种或多种实施例中，主进水管部525配置成为洗涤剂室221提供自来水，而柔顺剂进水管部526配置成为护理剂室222提供自来水。
参照图14，微气泡进水管部527具有进口端271，该进口端271用于连接到外部的水源，以便在需要的时候允许水沿着流向c流入微气泡进水管部527。直径变小锥形通道部272形成在微气泡进水管部527的水平部分内。在直径变小锥形通道部272的内部沿着水流方向c形成有一级直径变小锥形通道272a。替代地，在直径变小锥形通道部272内沿着水流方向可以形成两级或更多级的直径变小锥形通道。在直径变小锥形通道部272的下游端上形成喷孔273。喷孔273将一级直径变小锥形通道272a与位于喷孔273下游的流道连通在一起。水流进入微气泡进水管部527后必须流过一级直径变小锥形通道272a以在其中经受加压。加压后的水流通过喷孔273被迅速膨胀地喷出到下游流道并且在喷孔273附近造成负压。进气通道275形成在微气泡进水管部527的水平部分的下管壁上，并且定位靠近喷孔273。因此，在负压的作用下，外界空气通过进气通道275被吸入到微气泡进水管部527中并且与从喷孔273喷出的水流混合以产生气泡水。微气泡起泡器274也布置在微气泡进水管部527的水平部分内，并且位于直径变小锥形通道部272的下游。微气泡起泡器274横向于微气泡进水管部527布置，因此，气泡水需要先流过微气泡起泡器274后才能离开微气泡进水管部527并被微气泡起泡器274切割和混合而产生微气泡水。微气泡水然后被喷入处理剂盒522的洗涤剂室221和/或护理剂室222，从而帮助迅速地溶解位于洗涤剂室221中的洗涤剂和/或位于护理剂室222中的护理剂，例如柔顺剂。
在一种或多种实施例中，在一级直径变小锥形通道272a的内壁上能够形成有扰流部(图中未示出)。在一种或多种实施例中，扰流部可以是沿着该级直径变小锥形通道的内壁纵向延伸的至少一个扰流筋，例如多个扰流筋。在替代的实施例中，扰流部可以是在该级直径变小锥形通道的内壁上的至少一个径向突起部，例如一个或多个的柱状突起。在替代的实施例中，扰流部可以形成在最下游一级直径变小锥形通道的内壁上，或者形成在每一级直径变小锥形通道的内壁上。
在一种或多种实施例中，微气泡起泡器274为孔网结构。该孔网结构具有至少一道细孔的直径达微米级。优选地，细孔的直径在0～1000微米之间；更优选地，细孔的直径在 5～500微米之间。孔网结构可以是塑料栅栏，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，孔网结构可以是能够产生微气泡的其它孔网结构，例如由两个非微米级的蜂窝状结构组成的孔网结构。当气泡水流过孔网结构时，孔网结构对气泡水产生混合和切割的作用，从而产生微气泡水。
在一种或多种实施例中，在壳体521上还设有喷淋室276。喷淋室276位于处理剂盒522的上方。该喷淋室276的底部设有多个喷淋孔(图中未标出)，并且这些喷淋孔被配置成与处理剂盒522的洗涤剂室221和/或护理剂室222连通，以将来自微气泡起泡器274的微气泡水喷淋到洗涤剂室221和/或护理剂室222中。
图15是沿着图13的剖面线A-A截取的本发明微气泡处理剂盒组件52在第三实施方式中的第二实施例的剖视图。如图15所示，在该实施例中，处理剂盒522也具有并列布置的洗涤剂室221和护理剂室222。洗涤剂室221设置成用于容纳洗涤剂。护理剂室222设置成用于容纳柔顺剂。主进水管部525配置成为洗涤剂室221提供自来水，而柔顺剂进水管部526配置成为护理剂室222提供自来水。
参照图15，在该实施例中，微气泡进水管部527具有进口端271，该进口端271用于连接到外部的水源，以便在需要的时候允许水沿着流向c流入微气泡进水管部527。直径变小锥形通道部272形成在微气泡进水管部527的出口处。在直径变小锥形通道部272的内部沿着水流方向c形成有向下延伸的一级直径变小锥形通道272a。替代地，在直径变小锥形通道部272内沿着水流方向可以形成两级或更多级的直径变小锥形通道。在直径变小锥形通道部272的下游端上形成喷孔273。喷孔273将一级直径变小锥形通道272a与位于喷孔273下游的流道连通在一起。水流进入微气泡进水管部527后必须流过一级直径变小锥形通道272a以在其中经受加压。加压后的水流通过喷孔273被迅速膨胀地喷出到下游流道并且在喷孔273附近造成负压。如图15所示，在该实施例中，壳体521上还设有喷淋室276，喷淋室276位于处理剂盒522的上方。进气通道275形成在位于微气泡进水管部527与喷淋室276之间的连接部(图中未标出)上，并且定位也靠近喷孔273。可选地，在喷淋室276与连接部之间的接合处可以形成辅助进气通道275'，该辅助进气通道275'定位也靠近喷孔273。替代地，在壳体521可以只设置辅助进气通道275'用作进气通道。因此，在负压的作用下，外界空气通过进气通道275和/或辅助进气通道275'被吸入到由连接部围成的空间中并且与从喷孔273喷出的水流混合以产生气泡水。微气泡起泡器274布置在喷淋室276的底部并且覆盖位于喷淋室276底部上的喷淋孔。因此，气泡水需要先流过微气泡起泡器274而形成微气泡水后才能从喷淋孔喷淋到洗涤剂室221和/或护理剂室222中，从而帮助迅速地溶解位于洗涤剂室221中的洗涤剂和/或位于护理剂室222中的护理剂，例如柔顺剂。本实施例未提及的部分同上述实施例。
本发明还提供一种洗涤设备，该洗涤设备包括本发明的微气泡处理剂盒组件52。该微气泡处理剂盒组件52设置成在该洗涤设备内以提供处理剂微气泡水混合物。通过该微气泡处理剂盒组件，不仅能够提高洗涤设备的洗净能力，而且能够减少洗涤剂的用量并降低洗涤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。
参照图16，图16是本发明具有微气泡处理剂盒组件的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16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的侧壁上靠近顶端设有脱水孔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51和与进水阀51连通的微气泡处理剂盒组件52，微气泡处理剂盒组件52被安装在外桶21的顶部上方。水经由进水阀51进入微气泡处理剂盒组件52以利用微气泡水来快速溶解处理剂盒中的一种或多种处理剂，例如洗涤剂和/或一种或多种衣物护理剂。微气泡处理剂盒组件52然后将处理剂微气泡水混合物提供给外桶21，用于衣物清洗。水中的微气泡在破碎过程中对洗涤剂产生撞击，并且微气泡通过携带的负电荷也能够吸附洗涤剂，因此微气泡能够增加洗涤剂与水的混合程度，从而降低洗涤剂的用量并减少洗涤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，微气泡还增强了洗衣机的去污性能。
参照图17，图17是本发明具有微气泡处理剂盒组件的洗涤设备的另一种实施例的结构示意图。在该实施例中，洗涤设备为一种滚筒洗衣机9。
如图17所示，滚筒洗衣机9包括外壳91和位于外壳底部的地脚98。在外壳91的顶部设有上台面板94。外壳91的前侧(面对用户的操作侧)上设有允许用户向滚筒洗衣机内装填衣物等的门体97，而门体97上还设有能够看到洗衣机内部的观察窗96。在观察窗96与外壳91之间还设置密封窗垫961，并且该密封窗垫961固定在外壳91上。滚筒洗衣机9的控制面板95布置在外壳91的前侧的上部，以便于用户的操作。在外壳91的内部则布置有外筒92和内筒93。内筒93定位在外筒92的内部。内筒93通过传动轴932和轴承933连接到电机931(例如直驱电机)。在外壳91的后侧的上部上设有进水阀51，该进水阀51通过水管连接到微气泡处理剂盒组件52。如图17所示，微气泡处理剂盒组件52定位位于上台面板94的下方并且位于外筒92的上方。类似于上述实施例，水经由进水阀51通过水管进入微气泡处理剂盒组件52以利用微气泡水来快速溶解处理剂盒中的一种或多种处理剂，例如洗涤剂和/或一种或多种衣物护理剂。微气泡处理剂盒组件52然后将处理剂微气泡水混合物提供给外筒92，用于衣物清洗。
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。
