Definitions

  • the present invention relates to washing equipment, in particular to a water intake method of the washing equipment and a washing equipment using the water intake method.
  • 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.
  • Microbubbles can make the atomic clusters of water molecules smaller. Therefore, the gas molecules in the microbubbles are easier to dissolve into the gaps of the atomic clusters. At the same time, the gas molecules break the water interface and dissolve into the water more easily. Water molecules can always maintain Brownian motion and continue to collide. At the same time, the microbubbles are also settling and rupturing, and the gas stored in the microbubbles will rise. This causes the rising speed of the microbubbles to be greatly reduced.
  • microbubbles Since the rising speed of the microbubbles is slow, the meeting period of the microbubbles (ie, the lifespan of the microbubbles) is greatly extended. In this process, micro-bubbles gather and move in the liquid, resulting in high melting efficiency. A large number of microbubbles rupture in the water will also release a large amount of blasting force, forming negative ion water in the water, so it is easy to absorb the positively charged foreign objects floating in the liquid. The result is that the foreign matter will be absorbed by the microbubbles after it is destroyed by the breakage of the microbubbles, and then slowly float to the surface of the liquid. These characteristics make the microbubbles have strong cleaning and purification capabilities. In addition, the microbubbles can form a certain frequency of ultrasonic waves when they explode, so they have a sterilizing effect. At present, microbubbles have been widely used in washing machines such as washing machines.
  • the Chinese Published Invention Patent Application CN110073050A discloses a washing machine and a cleaning method.
  • the washing machine is provided with a water injection device, and the water injection device includes a first, a second, and a third water supply valve, wherein a fine bubble generator is provided downstream of the first water supply valve and upstream of the detergent box.
  • the fine bubble generator has a throttle part, a through part and a protrusion part.
  • the protruding part is arranged downstream of the throttling part and positioned in the middle of the through part, and generates microbubbles in the water by locally shrinking the cross section of the flow passage.
  • the fine-bubble water can be provided to the detergent box for dissolving the detergent through the fine-bubble generator.
  • the second water supply valve is used to supply tap water to the detergent box.
  • the mixing ratio of the fine bubble water and the tap water in the washing liquid can be controlled.
  • the drawback of the washing machine disclosed in CN110073050A is that the generation of the microbubbles of its microbubble generator all depends on the air dissolved in the tap water itself, so it is impossible to generate enough microbubbles in the water, and the protrusions are used to form the microbubbles. Bubbles are not efficient enough.
  • CN110073050A does not involve how to inject microbubble water and tap water. The main consequence of these defects to the washing machine is that the detergent cannot be dissolved efficiently enough, and the water saving effect of the washing machine is not good enough.
  • the present invention provides a water inlet method for washing equipment.
  • a microbubble spray head that generates microbubble water includes: after the washing device is started, determining a total set value of the water intake of the washing device based on the object to be washed; turning on the first water intake of the washing device Valve to inject the microbubble water; when the water intake of the microbubble water reaches a first set value, open the second water inlet valve of the washing device to inject non-microbubble water; and when the washing device When the water inlet volume reaches the total set value, the water inlet process of the washing equipment is completed.
  • the first water inlet valve is closed.
  • the first water inlet valve is kept open.
  • the method further includes: after the washing device is started, determining the amount of detergent to be added based on the objects to be washed.
  • the water intake method of a washing device with a microbubble nozzle capable of generating microbubble water includes that after the washing device is started, the washing device needs to be determined according to the items to be washed.
  • the water intake of microbubble water reaches the first set value
  • open the second water inlet valve of the washing equipment to inject non-microbubble water into the washing equipment until the water intake of the washing equipment reaches the total set value to complete the washing equipment
  • the water intake process is described in the water intake process.
  • Injecting microbubble water into the washing equipment first can realize the efficient dissolution of the detergent in the microbubble water, and because there are a large number of microbubbles in the water, it can also save water consumption, while the washing liquid level in the washing equipment remains unchanged. Since the amount of microbubble water produced is small, using the second water inlet valve to inject non-microbubble water, such as tap water, into the washing device can help quickly complete the water intake process of the washing device.

Description

洗涤设备的进水方法及使用该进水方法的洗涤设备 技术领域
本发明涉及洗涤设备，具体地涉及洗涤设备的进水方法和使用该进水方法的洗涤设备。
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)。微气泡能使使水分子的原子团变的更小，因此，微气泡中的气体分子更容易溶入原子团的间隙中，同时，气体分子打破了水的界面，也更容易溶入水中。水分子能够始终保持布朗运动，不断进行冲撞，同时微气泡也在沉降、破裂，微气泡内储存的气体会上升。这导致微气泡的上升速度大大降低。由于微气泡的上升速度缓慢，微气泡的会合期(即微气泡的寿命)因此被大大延长。在这个过程中，微气泡在液体中聚集和运动，导致融化效率高。大量微气泡在水中破裂还会放出大量的爆破力量，在水中形成负离子水，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。另外，微气泡在爆炸时能够形成一定频率的超声波，因此具有杀菌的作用。目前，微气泡已经被广泛应用于洗衣机等洗涤设备中。
例如，中国公开发明专利申请CN110073050A公开了洗衣机和清洁方法。具体地，该洗衣机设有注水装置，而该注水装置包括第一、第二和第三供水阀，其中，在第一供水阀的下游并且在洗涤剂盒的上游设有细微气泡产生器。该细微气泡产生器具有节流部、直通部和突出部。突出部布置在节流部的下游，并且定位在直通部的中部，通过局部地收缩流道截面而在水中产生微气泡。当第一供水阀打开时，通过细微气泡产生器可以向洗涤剂盒提供细微气泡水用于溶解洗涤剂。第二供水阀用于向洗涤剂盒提供自来水。通过控制第一供水阀和第二供水阀的开闭时间或定时时间，可以控制洗涤液中细微气泡水与自来水的混合比例。然而，CN110073050A所公开的洗衣机 存在的缺陷是其细微气泡产生器的微气泡的产生全部依赖于自来水自身中所溶解的空气，因此在水中无法产生足够多的细微气泡，并且利用突出部来形成细微气泡，效率也不够高。另外，在CN110073050A中也没有涉及如何注入微气泡水和自来水。这些缺陷给洗衣机带来的主要后果就是洗涤剂不能得到足够高效的溶解，洗衣机的节水效果也不够好。
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，即为了解决现有洗衣机的洗涤剂溶解效率不够高、节水效果不够好的技术问题，本发明提供了一种洗涤设备的进水方法，所述洗涤设备具有产生微气泡水的微气泡喷头，所述进水方法包括：在所述洗涤设备启动后，基于待洗物，确定洗涤设备的进水量的总设定值；打开洗涤设备的第一进水阀以注入所述微气泡水；当所述微气泡水的进水量达到第一设定值时，打开所述洗涤设备的第二进水阀以注入非微气泡水；以及当所述洗涤设备的进水量达到所述总设定值时，洗涤设备的进水过程完成。
在上述洗涤设备的进水方法的优选技术方案中，当所述微气泡水的进水量达到所述第一设定值时，所述第一进水阀关闭。
在上述洗涤设备的进水方法的优选技术方案中，在所述微气泡水的进水量达到所述第一设定值后，所述第一进水阀保持打开。
在上述洗涤设备的进水方法的优选技术方案中，所述方法还包括：在所述洗涤设备启动后，基于待洗物，确定洗涤剂的投放量。
本领域技术人员能够理解的是，在本发明的技术方案中，具有能够产生微气泡水的微气泡喷头的洗涤设备的进水方法包括在洗涤设备启动后，需要根据待洗物确定洗涤设备的进水量的总设定值，并且打开洗涤设备的第一进水阀以首先注入微气泡水。当微气泡水的进水量达到第一设定值时，再打开洗涤设备的第二进水阀以向洗涤设备注入非微气泡水，直到洗涤设备的进水量达到总设定值以完成洗涤设备的进水过程。先在洗涤设备内注入微气泡水，能够实现洗涤剂在微气泡水中的高效溶解，并且由于水中存在大量微气泡，还能够节省用水量，同时洗涤设备内的洗涤液面保持不变。由于微气泡水的产生量较小，因此利用第二进水阀在洗涤设备内注入非微气泡水，例如自来水，能够帮助快速完成洗涤设备的进水过程。
为了解决现有洗衣机的洗涤剂溶解效率不够高、节水效果不够好的技术问题，本发明还提供一种洗涤设备，其使用根据如上所述的洗涤设 备的进水方法，所述洗涤设备具有产生微气泡水的微气泡喷头，所述微气泡喷头包括一体式喷管和固定在所述一体式喷管的出口端上的微气泡起泡器，在所述一体式喷管内设有直径变小锥形通道部，在所述直径变小锥形通道部内沿着水流方向形成至少一级直径变小锥形通道，并且在所述直径变小锥形通道部下游端上形成有喷孔，所述喷孔配置成使得通过所述至少一级直径变小锥形通道加压的水流从所述喷孔膨胀喷出后在所述一体式喷管内产生负压；在所述一体式喷管上设有进气通道，所述进气通道定位成使得空气借助所述负压能够通过所述进气通道被吸入所述一体式喷管并且与所述水流混合产生气泡水，所述气泡水通过所述微气泡起泡器时形成微气泡水。
在上述洗涤设备的优选技术方案中，在直径变小锥形通道部的内壁上形成扰流部。
在上述洗涤设备的优选技术方案中，所述扰流部是设置在所述直径变小锥形通道部的内壁上的至少一个径向突起部或者是沿着所述直径变小锥形通道部的内壁纵向延伸的至少一个扰流筋。
在上述洗涤设备的优选技术方案中，所述微气泡起泡器包括孔网和孔网骨架，所述孔网通过所述孔网骨架附接到所述一体式喷管的出口端上。
在上述洗涤设备的优选技术方案中，所述孔网骨架上配置有至少一个溢流孔，所述至少一个溢流孔定位靠近所述孔网。
在上述洗涤设备的优选技术方案中，所述孔网具有至少一道细孔的直径达微米级。
本领域技术人员能够理解的是，在本发明的技术方案中，洗涤设备具有产生微气泡水的微气泡喷头。该微气泡喷头包括一体式喷管和固定在一体式喷管的出口端上的微气泡起泡器。在一体式喷管内设有直径变小锥形通道部，在直径变小锥形通道部内沿着水流方向形成至少一级直径变小锥形通道用于加压水流。在直径变小锥形通道部下游端上形成有喷孔，该喷孔配置成使得通过至少一级直径变小锥形通道加压的水流从喷孔膨胀喷出后在一体式喷管内产生负压用于吸入空气。在一体式喷管上设有进气通道，该进气通道定位成使得大量空气借助负压能够通过进气通道被吸入一体式喷管并且与水流混合产生气泡水，该气泡水通过所述微气泡起泡器时形成微气泡水。因此，通过该设计的微气泡喷头可以在洗涤设备内产生含有大量微气 泡的气泡水。首先向洗涤设备内注入这种微气泡水，不仅能够高效地溶解洗涤剂或洗衣粉，避免洗涤剂或洗衣粉的沉积，而且由于水中的大量微气泡，能够在不降低洗涤液面的情况下，就能减少用水量。另外，本发明的洗涤设备不仅通过减少洗涤用品的残留提高了对用户的健康呵护，而且通过满足用户的需求有效提高用户的满意度。
优选地，在直径变小锥形通道部的内壁上形成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，起泡器包括孔网和孔网骨架，所述孔网通过所述孔网骨架附接到所述一体式喷管的出口端上。在所述孔网骨架上配置有至少一个溢流孔，所述至少一个溢流孔定位靠近所述孔网。溢流孔能够防止多余的水淹没进气孔，从而阻止因进气孔被堵而使空气无法被吸入一体式喷管因此无法产生微气泡水的情形。

为了解决现有洗衣机的洗涤剂溶解效率不够高、节水效果不够好的技术问题，本发明提供了一种洗涤设备的进水方法，该洗涤设备具有产生微气泡水的微气泡喷头。该进水方法包括：在洗涤设备启动后，基于待洗物，确定洗涤设备的进水量的总设定值；打开洗涤设备的第一进水阀以注入微气泡水；当微气泡水的进水量达到第一设定值时，打开洗涤设备的第二进水阀 以注入非微气泡水；以及当洗涤设备的进水量达到总设定值时，洗涤设备的进水过程完成。待洗物例如是需要洗涤的衣物或其它可洗涤的生活用品。
本发明还提供一种洗涤设备，该洗涤设备具有产生微气泡水的微气泡喷头52并且使用如上所述的进水方法。该微气泡喷头52包括一体式喷管521和固定在一体式喷管521的出口端212上的微气泡起泡器522。在一体式喷管521内设有直径变小锥形通道部219。在直径变小锥形通道部219内沿着水流方向C形成至少一级直径变小锥形通道用于加压水流。在直径变小锥形通道部219下游端上形成有喷孔217，该喷孔配置成使得通过至少一级直径变小锥形通道加压的水流从喷孔膨胀喷出后在一体式喷管521内产生负压用于吸入空气。在一体式喷管521上设有进气通道，该进气通道定位成使得大量空气借助负压能够通过进气通道被吸入一体式喷管521并且与水流混合产生气泡水，该气泡水通过微气泡起泡器522时形成微气泡水。因此，通过该设计的微气泡喷头可以在洗涤设备内产生含有大量微气泡的气泡水。首先向洗涤设备内注入这种微气泡水，不仅能够高效地溶解洗涤剂或洗衣粉，避免洗涤剂或洗衣粉的沉积，而且由于水中的大量微气泡，能够在不降低洗涤液面的情况下，就能减少用水量，从而不仅有利于用户的健康，而且还能改善用户的体验。
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通道横截面沿着水流方向逐渐变小从而使该通道呈大致锥形的结构。
参照图1，图1是本发明洗涤设备的第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，本发明的洗涤设备可以是烘干一体机。
如图1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连通的微气泡喷头52，微气泡喷头52被安装在外桶21的顶部上。水经由进水阀51进入微气泡喷头52以产生包含大量微气泡 的微气泡水，微气泡喷头52将微气泡水先喷入洗涤剂盒以与洗涤剂混合，然后经由洗涤剂盒进入内桶31，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。可选地，微气泡喷头还可以直接将携带大量微气泡的微气泡水喷入洗衣机的外桶21或内桶31，以进一步降低洗涤剂的用量并增强洗衣机的清洁能力。
参照图2，图2是本发明洗涤设备的第二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2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喷头52。如图2所示，微气泡喷头52定位靠近外壳91的前侧上部，并且位于控制面板95的下方。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以产生包含大量微气泡的微气泡水，微气泡喷头52将微气泡水先喷入洗涤剂盒以与洗涤剂混合，然后经由洗涤剂盒进入内筒93，用于衣物清洗。可选地，微气泡喷头52还可以直接将携带大量微气泡的微气泡水喷入洗衣机的外筒92或内筒93，以进一步降低洗涤剂的用量并增强洗衣机的清洁能力
参照图3-图7，图3-图7是本发明洗涤设备的微气泡喷头52的实施例的示意图，其中，图3是是本发明洗涤设备的微气泡喷头的实施例的立体示意图，图4是图3所示的本发明洗涤设备的微气泡喷头的实施例的俯视图，图5是图3所示的本发明洗涤设备的微气泡喷头的实施例的左视图，图6是图3所示的本发明洗涤设备的微气泡喷头的实施例的正视图，以及图7是沿着图6的剖面线A-A截取的本发明洗涤设备的微气泡喷头的实施例的剖视图。如图 3-7所示，在一种或多种实施例中，本发明洗涤设备的微气泡喷头52包括一体式喷管521。在一体式喷管521的出口端212上安装有微气泡起泡器522，微气泡起泡器522配置成能够在气泡水流过其时切割和混合气泡水而产生含有大量微气泡的微气泡水。
参照图3，在一种或多种实施例中，一体式喷管521具有进口端211和出口端212。在出口端212上固定有微气泡起泡器522，而进口端211则用于连接到外部水源。可选地，在进口端211上可设置止脱部213，例如围绕进口端211的外壁径向向外隆起的止脱筋或者进口端211的外壁向内凹进的环形沟槽结构，能够防止一体式喷管从其所连接的提供水源的管道上脱落。
继续参照图3，在一种或多种实施例中，在一体式喷管521的外壁上设有第一固定安装部214A，第二固定安装部214B，以及定位部215，用于将微气泡喷头52定位和固定到预定位置。
参照图4-6，第一固定安装部214A和第二固定安装部214B对称地定位在一体式喷管521的外壁上，并且位于一体式喷管521的中部。定位部215则为长条肋，从一体式喷管521的外壁径向向外突出，并且沿着一体式喷管521的纵向延伸。第一固定安装部214A和第二固定安装部214B分布在定位部215的两侧。可选地，在一体式喷管521上只设置一个固定安装部，而定位部215也可以采用其它合适的形式。
在一种或多种实施例中，第一和第二固定安装部214A，214B为螺钉孔结构，以通过螺钉将喷头52固定到目标位置。然而，固定安装部可采用任何合适的连接结构，例如卡扣连接结构、焊接连接结构等。
参照图7，在一体式喷管521内，设有直径变小锥形通道部219。在直径变小锥形通道部219内，沿着水流方向C具有第一级直径变小锥形通道219A和第二级直径变小锥形通道219B。第一级直径变小锥形通道219A的最小直径大于第二级直径变小锥形通道219B的最大直径。在直径变小锥形通道部的下游端上形成有喷孔217。该喷孔217将第一级直径变小锥形通道219A和第二级直径变小锥形通道219B与一体式喷管521的下游通道连通在一起。在替代的一种或多种实施例中，在直径变小锥形通道部219内可以只形成一级直径变小锥形通道，也可以形成多于两级的直径变小锥形通道。
继续参照图7，在第二级直径变小锥形通道219B的内壁上形成有扰流部218。在一种或多种实施例中，扰流部218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218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218也可以形成在第一级直径变小锥形通道219A的内壁上，或者每一级直径变小锥形通道的内壁上都形成有扰流部。
如图7所示，直径变小锥形通道部219的对应第二级直径变小锥形通道219B的部分的外壁与一体式喷管521的内壁分离，从而在该外壁与一体式喷管521的内壁之间形成环形间隙300。该环形间隙300有助于空气与水流的混合，进而产生更多的微气泡。
如图7所示，一体式喷管521的管壁上形成有两排布置成环形的多个进气孔216，这些进气孔一起构成一体式喷管521上的进气通道。这些进气孔216定位都靠近喷孔217。水流从一体式喷管521的进口端211进入，先流过第一级和第二级直径变小锥形通道219A、219B以加压(加速)水流，而扰流部218则加大水流的涡流；加压后的水流从喷孔217被快速膨胀地喷入到一体式喷管521的下游通道，并且在其中产生负压；在负压的作用下，大量外部空气从进气孔216沿着方向E被吸入一体式喷管521并且与其中的水流混合而产生气泡水。在替代的实施例中，根据需要，可以设置更多或更少的进气孔，并且能够以其它方式排布，例如以交错方式排列。
继续参照图3-7，微气泡起泡器522包括孔网221和孔网骨架222。孔网221通过孔网骨架222附接到一体式喷管521的出口端212上。
在一种或多种实施例中，孔网221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221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221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221时，孔网221对气泡水产生混合和切割的作用，从而产生微气泡水。
参照图7，孔网骨架222呈圆筒状以便能够套在一体式喷管521的出口端212上。在一种或多种实施例中，孔网骨架222的内壁上设置有内螺纹以与出口端212的外壁上的外螺纹啮合。可选地，在啮合的外螺纹与内螺纹之间可以预留设定的间隙以允许空气通过该间隙被吸入一体式喷管内。在替代的实施例中，孔网骨架222可以通过其它连接方式与一体式喷管521的出口端连接，例如焊接的方式。
如图7所示，在一种或多种实施例中，孔网骨架222沿着其外周设有多个溢流孔223，并且这些溢流孔定位靠近孔网221。当气泡水不能及时从孔网221通过时，多余的气泡水能够从溢流孔223流出，从而能够防止多余的水回流而淹没进气孔216。因此，溢流孔223能够阻止因进气孔被堵而使空气无法被吸入一体式喷管因此无法产生微气泡水的情形。在替代的实施例中，根据需要，可以设置更多或更少的溢流孔223。
进一步参照图7，在一种或多种实施例中，在孔网骨架222与一体式喷管521的出口端212之间还设置压环225。相应地，孔网221的周边上设有连接部224。压环225将该连接部224压在孔网骨架222的端部内壁上，从而能够牢固地固定孔网221，使得孔网221在经受高压水流冲击的时候不会从一体式喷管521的出口端212上脱落。在替代的实施例中，孔网221也可以利用其它结构进行固定，例如用卡簧卡住孔网。在一种或多种实施例中，压环225上也设有多个压环孔226。在喷射水流流量不大的情况下，这些压环孔226可以用于将空气吸入并与水流混合。在喷射水流流量比较大时，允许部分水从这些压环孔226溢出，由此不仅能够帮助清洁孔网，而且还能阻止多余的水逆流通过进气通道而导致无法通过这些进气通道吸入空气。
下面基于本发明的上述波轮洗衣机和滚筒洗衣机实施例描述本发明洗涤设备的进水方法。
图8是本发明洗涤设备的进水方法的第一种实施例的流程图。如图8所示，在该实施例中，首先给波轮或滚筒洗衣机通电以启动洗衣机(步骤S1)。然后，对洗衣机内的待洗衣物进行称重，并且基于获得的待洗衣物的重量，确定洗衣机的进水量的总设定值(步骤S2)。可选地，基于获得的待洗衣物的重量，还能够确定洗涤剂或洗衣粉的投放量。进一步地，在步骤S3中，首先打开洗衣机的第一进水阀(图中未示出)以向洗衣机的洗涤剂盒 注入微气泡水。该微气泡水通过洗衣机的微气泡喷头52产生。在开始注入微气泡水后，洗衣机的控制系统负责检测洗衣机内的进水量(也是微气泡水进水量)(步骤S4)并且判断微气泡的进水量是否达到系统预定的第一设定值(步骤S5)。可选地，该进水量可以基于洗衣机内的进水水位获得，也可以基于微气泡喷头的流量与注入微气泡水的时间获得。当微气泡水进水量未达到第一设定值时，第一进水阀保持打开以继续注入微气泡水。当微气泡水进水量达到第一设定值时，关闭第一进水阀(因此停止注入微气泡水)，同时打开洗衣机的第二进水阀(图中未示出)以向洗衣机注入非微气泡水，例如自来水或井水等水源(步骤S6)。洗衣机的控制系统继续检测洗衣机内的进水量(包括微气泡水和非微气泡水)并且判断洗衣机内的进水量是否达到预设的总设定值(步骤S7)。当洗衣机内的进水量没有达到预设的总设定值时，第二进水阀保持打开状态以继续注入非微气泡水。当洗衣机内的进水量达到预设的总设定值时，关闭第二进水阀，洗衣机的进水过程完成(步骤S8)。洗衣机然后可以进入由用户设定的洗涤等过程。
图9是本发明洗涤设备的进水方法的第二种实施例的流程图。如图9所示，在该实施例中，步骤S1、S2、S3、S4、S5分别同上述实施例中的步骤S1、S2、S3、S4、S5。在步骤S5中，当微气泡水进水量被判断达到第一设定值时，打开第二进水阀以向洗衣机注入非微气泡水，同时第一进水阀保持打开以继续注入微气泡水(步骤S6’)。换言之，根据步骤S6’，在微气泡水进水量达到第一设定值后，洗衣机被同时注入微气泡水和非微气泡水。洗衣机的控制系统也继续检测洗衣机内的进水量(包括微气泡水和非微气泡水)并且判断洗衣机内的进水量是否达到预设的总设定值(步骤S7)。当洗衣机内的进水量没有达到预设的总设定值时，第一和第二进水阀均保持打开。当洗衣机内的进水量达到预设的总设定值时，关闭第一和第二进水阀，洗衣机的进水过程完成(步骤S8)。洗衣机然后可以进入由用户设定的洗涤等过程。
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。
