Description

一种泡沫局部清洗装置及其控制方法 技术领域
本发明属于衣物处理技术领域，具体地说，涉及一种泡沫局部清洗装置及洗衣机。
背景技术
洗衣机为通过电力带动产生的机械力清洗洗涤物的机器，对于衬衫等类衣服，领口和袖口等普遍比其他位置脏污程度高，而现有的洗衣机在洗涤过程中，对衣物的领口、袖口等局部位置的洗涤效果较差。
现有技术中往往需要通过在洗衣机上额外加设超声波洗涤来达到目的。
例如，申请号为CN200520069251.1的中国专利公开了一种带有局部超声波洗涤装置的洗衣机，包括洗衣机机身和超声波洗涤装置，其中超声波洗涤装置由超声波发生器、换能器、装置盒体和换能器底座组成；超声波发生器安装在电脑板里，并与换能器连接；换能器安装在装置盒体内的底座上，由盖板压紧。超声波洗涤装置由一个定位支座固定，通过定位支座安装在洗衣机工作台的后部。
申请号为CN2017101131757的中国专利公开了一种衣物局部清洗结构及洗衣机，所述衣物局部清洗结构可拆卸的设置在洗衣机盘座上，与洗衣机进水水路/洗涤剂盒相连，所述衣物局部清洗结构包括压板和支撑板，所述压板包括超声波换能器，所述支撑板包括一进水空腔，所述压板的形状与支撑板配合，向支撑板方向压紧后，彼此之间形成夹持衣物待洗局部的细缝，夹持衣物并超声清洗其待洗的局部。
上述方案虽然在一定程度上解决了洗衣机不能清洗脏污程度高的局部位置的问题，但是，在洗衣机上额外设置超声波洗涤无疑增加了洗衣机的成本，降低了洗衣机的市场竞争力。
有鉴于此特提出本发明。

详细的，在使用上述的泡沫局部清洗装置时，通过连杆组件3将泡沫清洗组件2从外壳1的内部移动至外壳1的外部，方便局部洗涤时或者进行洗涤试剂的预涂抹，洗涤试剂直接起泡，不易从衣物上掉落，省去沾水搓洗起泡的过程，使泡沫中的有效成份得到充分利用，大大提高了清洁、除菌、滋润的效果。
在使用结束后，通过连杆组件3将泡沫清洗组件2从外壳1的外部移动至外壳1的内部，避免泡沫清洗组件2占用较大空间。
进一步的方案中，所述连杆组件3包括连杆部31、第一滑块32和第二滑块33。
所述连杆部31能够绕一旋转中心转动；所述第一滑块32和第二滑块33分别设置在所述连杆部31的两端，并相对于所述外壳1滑动。
所述第二滑块33还连接有拉手部4，所述拉手部4与所述泡沫清洗组件2连接，推拉所述拉手部4使所述泡沫清洗组件2在所述收纳位置和所述清洗位置之间移动时，所述第二滑块33相对于所述外壳1滑动并通过所述连杆部31带动所述第一滑块32相对于所述外壳1滑动。

在使用上述的泡沫局部清洗装置时，用户拉动拉手部4使泡沫清洗组件2从外壳1的内部向外部移动的同时带动与拉手部4连接的第二滑块33在外壳1上以第一方向滑动。此时，第二滑块33使连杆部31绕旋转中心旋转并使第一滑块32在外壳1上以第二方向滑动，所述第一方向与所述第二方向相反。
在使用结束后，用户推动拉手部4使泡沫清洗组件2从外壳1的外部向内部移动的同时带动与拉手部4连接的第二滑块33在外壳1上以第二方向滑动，此时，第二滑块33使连杆部31绕旋转中心旋转并使第一滑块32在外壳1上以第一方向滑动。
上述第一方向可以为靠近用户的方向，第二方向可以为远离用户的方向。

上述方案中，用户通过推拉底座41从而实现将所述的泡沫清洗组件2在收纳位置和清洗位置之间移动，提高操作时的稳定性。
此外，在底座41上设置镂空部42，能够使泡沫清洗组件2产生的水流及时流走，避免泡沫聚集粘附在泡沫清洗组件2上，引起堵塞等问题。

上述方案，将所述泡沫发生单元23和所述第二感应单元24集成一体设置在壳体25内，只在壳体25的底壁上预留出洗涤剂泡沫的出口，提高装置整体的美观度，提升用户的使用体验。
而且，将所述泡沫发生单元23的出口设置在相对于所述第二感应单元24的感应端位于远离所述连接壁43的位置，可避免衣物还未到达泡沫发生单元23的出口即开始出洗涤剂泡沫的情况发生。

在本发明的一些实施例中，上述泡沫清洗组件2不需要设置拉手部4就可以在收纳位置 和清洗位置之间进行切换，如图6至图8所示。
具体的方案中，泡沫局部清洗装置除了包括外壳1以及泡沫清洗组件2以外，还包括用于开闭所述外壳1的开口的门体13。
连杆组件3的一端与所述门体13连接，另一端与所述泡沫清洗组件2连接。
如图6所示，当用户需要使用泡沫清洗组件2时，所述门体13打开所述外壳1的开口，通过所述连杆组件3使所述泡沫清洗组件2由所述收纳位置向所述清洗位置移动。
如图7所示，当用户使用泡沫清洗组件2结束后，推动所述泡沫清洗组件2使其由所述清洗位置向所述收纳位置移动时，通过所述连杆组件3使所述门体13关闭所述外壳1的开口。
具体的，所述连杆组件3包括连杆部31、第一滑块32和第二滑块33。
所述连杆部31能够绕一旋转中心转动；所述第一滑块32和第二滑块33分别设置在所述连杆部31的两端，并相对于所述外壳1滑动，所述门体13通过转动部与所述第一滑块32连接，所述泡沫清洗组件2与所述第二滑块33连接；所述门体13打开所述外壳1的开口时收纳于所述外壳1内。
进一步的，所述第一滑块32上设有具有通孔结构的安装柱，所述安装柱的上方设置有第一挡板；所述转动部插设在所述安装柱的通孔结构内，且所述转动部朝向所述安装柱的一侧设置有第二挡板；所述安装柱的外部套设有扭簧，所述扭簧的两扭臂分别与所述第一挡板和所述第二挡板限位配合。
详细的，所述外壳1上设置有第一滑槽11和第二滑槽12；所述第一滑块32和所述第二滑块33分别对应设置于所述第一滑槽11和所述第二滑槽12内，并在所述第一滑槽11和所述第二滑槽12内滑动。
上述第一滑槽11和第二滑槽12与第一滑块32和第二滑块33一一对应。在一个实施方案中，第一滑块32和第二滑块33的运动轨迹为直线运动，在实际应用中，可以根据需要将第一滑块32和第二滑块33的运动轨迹设置为弧形等，第一滑块32和第二滑块33在第一滑槽11和第二滑槽12的限位作用下，形成其运动的轨迹。
进一步的方案中，所述连杆部31包括第一连杆311和第二连杆312。
所述第一连杆311的一端与所述第一滑块32连接，另一端与所述第二连杆312滑动连接，所述第二连杆312的另一端与所述第二滑块33连接。
所述第二连杆312连接有旋转轴313并能够绕所述旋转轴313转动；所述第二滑块33在所述第二滑槽12内滑动带动所述第二连杆312绕所述旋转轴313转动时，使所述第一连杆311能够沿所述第二连杆312的长度方向相对于所述第二连杆312滑动，并带动所述第一滑块32在所述第一滑槽11内滑动。
具体的，第二连杆312朝向外壳1一侧，在第二连杆312的长度方向上设置有连杆槽，第一连杆311在旋转时，能够在连杆槽的范围内，在第二连杆312的长度方向上伸入或者伸出实现其相对于第二连杆312滑动。第二连杆312在其长度方向上还设置有第二开口，第二滑块33上设置有与第二开口配合的第二导向柱，连杆部31转动时，第二导向柱在第二开口的作用下，驱动第二滑块33沿第二滑槽12滑动，同时第一连杆311设置有与第二开口配合的第一导向柱，同理，连杆部31转动时，第一导向柱在第二开口的作用下，驱动第一滑块32沿第一滑槽11滑动，第一连杆311还设置有与旋转轴313配合的第一开口，第一连杆311在第二连杆312长度方向上伸入或者伸出时，第一连杆311的第一开口也起到了导向作用，同时也避免第一连杆311偏离连杆槽。
更进一步地，外壳1上设置有第一限位部和第二限位部，第二滑块33上设置有定位部，定位部分别与第一限位部和第二限位部配合，实现在一定范围内连杆部31的旋转运动。
第一滑块32一端与第一连杆311转动配合，另一端设置有安装部，安装部为具有通孔结构的圆柱形安装柱，与安装部配合的还设置有转动部，转动部连接门体13。安装部上设置有第一挡板，转动部上设置有第二挡板，安装部的外侧设置有与第一挡板和第二挡板配合的扭簧，外壳1上设置有一引导部，扭簧与设置于外壳1内侧的引导部配合，扭簧和引导部实现了直线运动和旋转运动之间的切换。引导部呈弧形的引导结构，扭簧在直线运动转变为旋转运动后，提供回复力，此种设置，使得连杆部31的旋转运动，转换成第一滑块32的直线运动后，又将第一滑块32的直线运动转化为转动部的旋转运动，反之亦然。
用户手动打开门体13时，门体13在由竖直位置向水平位置转换的过程中，带动转动部旋转并带动第一滑块32在外壳1上向后滑动，第一滑块32在滑动的过程中带动第一连杆311和第二连杆312绕旋转中心旋转，并带动第二滑块33相对于外壳1向前滑动，此时，第二滑块33再带动泡沫清洗组件2由外壳1的内部向外壳1的外部移动，由此，实现泡沫清洗组件2由收纳位置向清洗位置移动。
反之，用户手动推动泡沫清洗组件2时，泡沫清洗组件2带动第二滑块33在外壳1上向后滑动，使第二连杆312绕旋转中心旋转，同时也驱动第一连杆311绕旋转中心旋转，带动 第一滑块32相对于外壳1向前滑动，同时，带动转动部旋转将门体13由水平位置向竖直位置转换关闭外壳1的开口，由此，实现泡沫清洗组件2由清洗位置向收纳位置移动。
在本发明的一些实施例中，所述连杆组件3还包括驱动部，所述驱动部与所述连杆部31连接，驱动所述连杆部31绕所述旋转中心转动。驱动部可以为电机。
进一步的方案中，所述门体13打开所述外壳1的开口时，所述驱动部检测到电流信号后驱动所述连杆部31绕所述旋转中心向第一方向转动，使所述泡沫清洗组件2自动由所述收纳位置向所述清洗位置移动。
推动所述泡沫清洗组件2使其由所述清洗位置向所述收纳位置移动时，所述驱动部检测到电流信号后驱动所述连杆部31绕所述旋转中心向第二方向转动，使所述门体13关闭自动所述外壳1的开口。
上述方案可辅助泡沫清洗组件2在收纳位置和清洗位置之间相互切换，提高用户的使用体验。
本发明的一些实施例中还提供一种泡沫局部清洗装置的控制方法，应用于上述的泡沫局部清洗装置。
泡沫局部清洗装置包括出水组件和洗涤剂泡沫发生组件。
所述出水组件用于在局部清洗时提供清洗水；洗涤剂泡沫发生组件，用于在局部清洗时提供泡沫状洗涤剂。
优选的，出水组件包括出水单元21和控制所述出水单元21是否被触发的第一感应单元22；所述洗涤剂泡沫发生组件包括所述泡沫发生单元23和控制所述泡沫发生单元23是否被触发的第二感应单元24。
如图9和图10所示，所述控制方法包括以下步骤：
确定所述出水组件的感应端距离遮挡物的距离是否小于其触发距离，若是，控制所述出水组件处于非触发状态，若否，控制所述出水组件处于触发状态；
确定所述洗涤剂泡沫发生组件的感应端距离遮挡物的距离是否小于其触发距离，若是，控制所述洗涤剂泡沫发生组件处于触发状态，若否，控制所述洗涤剂泡沫发生组件处于非触发状态。
具体的，所述泡沫局部清洗装置还包括外壳1，所述出水组件和所述洗涤剂泡沫发生组 件相对于所述外壳1具有收纳位置和清洗位置，并在所述收纳位置和所述清洗位置之间切换。
所述出水组件包括所述出水单元21、第一感应单元22；洗涤剂泡沫发生组件包括所述泡沫发生单元23和第二感应单元24。
在所述收纳位置时，所述外壳1的底壁构成所述出水组件和所述洗涤剂泡沫发生组件的遮挡物；在所述清洗位置时，待清洗物构成所述出水组件和所述洗涤剂泡沫发生组件的遮挡物。
现有技术中的感应单元均为感应到遮挡物时出水或者出洗涤剂，但是本发明的上述第一感应单元22的控制逻辑与现有的控制逻辑则是相反的。这是由于本发明的所述出水组件和所述洗涤剂泡沫发生组件相对于所述外壳1具有收纳位置和清洗位置。
为了尽可能地减小泡沫局部清洗装置占用洗衣机的空间，将外壳1设计地尽量小，因此，在收纳位置时，出水组件以及洗涤剂泡沫发生组件应尽量的紧凑。而出水组件设置在洗涤剂泡沫发生组件的下方，这就导致在收纳位置时，洗涤剂泡沫发生组件与外壳1的底壁之间的距离较大，应至少大于第二感应单元24的触发距离，出水组件的第一感应单元22与外壳1的底壁之间的距离较小，小于第一感应单元22的触发距离。
如果采用现有的控制逻辑，则会出现在收纳位置时，第一感应单元22时刻感应到遮挡物，持续出水的情况。
为解决上述技术问题，本发明将出水组件的控制逻辑修改为确定所述出水组件的感应端距离遮挡物的距离小于其触发距离时控制所述出水组件处于非触发状态，出水组件不能被启动出水，确定所述出水组件的感应端距离遮挡物的距离大于或等于其触发距离时控制所述出水组件处于触发状态，出水组件能够被启动出水。而洗涤剂泡沫发生组件的控制逻辑则采用现有的控制逻辑，即确定所述洗涤剂泡沫发生组件的感应端距离遮挡物的距离小于其触发距离时控制所述洗涤剂泡沫发生组件处于触发状态，洗涤剂泡沫发生组件能够被触发出洗涤剂，确定所述洗涤剂泡沫发生组件的感应端距离遮挡物的距离大于等于其触发距离时，控制所述洗涤剂泡沫发生组件处于非触发状态，洗涤剂泡沫发生组件不能够被触发出洗涤剂。
上述控制方法不仅解决了泡沫局部清洗装置结构紧凑所造成的在收纳位置时出水组件持续出水的技术问题，而且，对于在清洗位置时也有利于控制出水单元21以及泡沫发生单元23。
详细的，以所述出水组件和所述洗涤剂泡沫发生组件相对于所述外壳1处于清洗位置的 状态下，泡沫局部清洗装置设置在洗衣机的盘座5上为例进行说明。当用户暂未将衣物置于泡沫局部清洗装置下部时，第一感应单元22感应不到遮挡物，出水单元21处于触发状态，可能持续出水，也可能按照设定频率间断地出水，第二感应单元24感应不到遮挡物，泡沫发生单元23处于非触发状态，泡沫发生单元23不出洗涤剂泡沫。当用户将衣物置于泡沫局部清洗装置下部时，第一感应单元22感应到遮挡物，出水单元21转变为非触发状态不出水，第二感应单元24感应到遮挡物，泡沫发生单元23处于触发状态，泡沫发生单元23出洗涤剂泡沫。
由于控制的滞后性，当用户把衣物置于泡沫局部清洗装置下方时，距离出水单元21停止出水之间具有一定的延时，利用这一段延时可以将衣物打湿。
更进一步的是，可以为第一感应单元22感应到遮挡物后出水单元21由触发状态向非触发状态转变设定一延时时间，设定的延时时间能够保证出水足以将衣物打湿。而将第二感应单元24感应到遮挡物后泡沫发生单元23由非触发状态向触发状态转变设定上述的延时时间，这样，出水以及出洗涤剂则可以做到无缝对接。
进一步的方案中，控制所述洗涤剂泡沫发生组件处于触发状态之后包括：控制所述洗涤剂泡沫发生组件启动设定时间出洗涤剂后暂停启动，直至再次确定所述洗涤剂泡沫发生组件的感应端距离遮挡物的距离是否小于其触发距离。
上述方案可防止误触发导致的出液不止的情况发生。
需要注意的是，可以在洗衣机的洗涤桶或者外壳1上合适的位置设置触发位置的标识，以便用户将衣物准确地置于第一感应单元22和第二感应单元24的触发范围内。
可替换的实施方案中，控制所述出水组件处于触发状态之后包括：控制所述出水组件启动出水；判断所述洗涤剂泡沫发生组件是否启动出洗涤剂，若是，控制所述出水组件暂停启动出水。
对于用户的某些特殊需求，例如，不希望在打湿衣物的情况下涂抹泡沫洗涤剂时，用户将衣物置于泡沫局部清洗装置下方时，应特别注意不要置于出水单元21的下方，此时，第一感应单元22感应不到遮挡物，持续出水，但是第二感应单元24感应到遮挡物，控制泡沫发生单元23出洗涤剂泡沫，此时，控制单元检测到泡沫发生单元23以及处于触发状态并启动出洗涤剂后，则应在即使第一感应单元22并未感应到遮挡物的情况下控制出水单元21停止出水。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
