Description

防泡沫外溢单元和衣物处理设备 技术领域
本发明涉及衣物处理技术领域，具体涉及一种防泡沫外溢单元和衣物处理设备。
背景技术
洗衣机是利用电能来洗涤衣物的清洁型电器，随着生活节奏的加快以及人们对生活舒适度的高要求，洗衣机已经成为人们日常生活中必不可少的家用电器。随着技术的进步，现有的大部分洗衣机都能实现自动进水功能。以滚筒洗衣机为例，通常滚筒洗衣机的进水管通过电磁阀与洗涤剂盒组件连通，洗涤剂盒组件的盒出管通过连接管与外筒上的外筒管连通，从而形成进水管路。洗涤程序开始后，水源由进水管依次流经洗涤剂盒、连接管和外筒管后，流入外筒和内筒。然而受结构上的限制，上述进水管路也不可避免地存在一些问题。
在洗涤过程中，内筒和外筒会产生大量的泡沫，随着内筒的高速运转，泡沫会被挤出并通过外筒管上涌。一部分泡沫随进水管路逆流至洗涤盒内，甚至从洗涤剂盒与洗衣机壳体之间的缝隙溢出至洗衣机的外表面及地面上，给用户带来极大的困扰；更为严重的是，另一部分外溢的泡沫可能由洗涤剂盒与洗衣机之间的缝隙流入洗衣机的内部，容易造成洗衣机短路而导致触电事故发生。再加上现有洗衣机多带有烘干功能，泡沫还可能会随着烘干风道管进入加热单元和风机单元，进而存在部件损坏及触电的风险。
相应地，本领域需要一种新的防泡沫外溢单元和衣物处理设备来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有的洗衣机存在的泡沫容易通过进水管路外溢的问题，本发明提供了一种防泡沫外溢单元，所述防泡沫外溢单元包括壳体和设置于所述壳体内的活动件， 所述壳体具有进水口和出水口，所述进水口处设置有缩径段，当洗涤水流入所述进水口时，所述活动件被洗涤水顶起从而所述进水口与所述出水口连通，当洗涤水流出所述出水口后，所述活动件在重力的作用下下落至所述缩径段并将所述进水口密封。
在上述防泡沫外溢单元的优选技术方案中，洗涤水的进水方向与出水方向具有夹角。
在上述防泡沫外溢单元的优选技术方案中，所述出水口处设置有用于防止所述活动件移动出所述壳体的限位结构。
在上述防泡沫外溢单元的优选技术方案中，所述限位结构为限位筋，所述限位筋的末端由所述出水口向所述壳体内部延伸。
在上述防泡沫外溢单元的优选技术方案中，所述缩径段设置有与所述活动件相匹配的内环面。
在上述防泡沫外溢单元的优选技术方案中，所述活动件为球结构。
在上述防泡沫外溢单元的优选技术方案中，所述壳体沿洗涤水的出水方向的长度大于球结构的直径，从而所述球结构能够沿所述出水方向晃动；并且/或者所述内环面远离所述进水口的一端的圆形直径小于所述球结构的直径。
在上述防泡沫外溢单元的优选技术方案中，所述防泡沫外溢单元还包括进水管壳和出水管壳，所述进水管壳和所述出水管壳分别与所述防泡沫外溢单元的进水口和出水口连接。
本发明还提供了一种衣物处理设备，包括进水管路，所述进水管路上设置有上述优选技术方案中任一项所述的防泡沫外溢单元。
在上述衣物处理设备的优选技术方案中，所述衣物处理设备为滚筒洗衣机，所述进水管路包括洗涤剂盒组件的盒出管、外筒的外筒管以及设置于二者之间的连接管，所述防泡沫外溢单元设置于所述盒出管与所述连接管之间或所述连接管与所述外筒管之间。
本领域技术人员能够理解的是，在本发明的优选技术方案中，防泡沫外溢单元包括壳体和设置于壳体内的活动件，壳体具有进水口和出水口，进水口处设置有缩径段，当洗涤水流入进水口时，活动件被洗 涤水顶起从而进水口与出水口连通，当洗涤水流出出水口后，活动件在重力的作用下下落至缩径段并将进水口密封。
通过上述设置方式，本发明的防泡沫外溢单元在应用于衣物处理设备时，能够有效防止衣物处理设备在运行过程中产生的泡沫沿进水管路回流和外溢的问题，提高衣物处理设备的运行安全性。具体而言，通过活动件在洗涤水流入进水口时被洗涤水顶起，从而进水口与出水口连通的设置方式，本发明的防泡沫外溢单元能够在进水过程中保证进水流畅度与进水效率；而通过在洗涤水流出出水口后活动件在重力作用下密封缩径段的设置方式，则能够在进水结束后实现对进水管路的完全密封，保证泡沫无法沿进水管路回流和外溢。也就是说，本发明有效地解决了现有衣物处理设备存在的泡沫容易通过进水管路外溢的问题，提高了衣物处理设备的安全性，并且由于防泡沫外溢单元结构简单可靠、设计巧妙，因此适宜大规模推广使用。

此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
首先参照图1至图5，对本发明的滚筒洗衣机进行描述。其中，图1为本发明的滚筒洗衣机的内部结构的示意图；图2为本发明的滚筒洗衣机的内部结构的主视图；图3为图2在A-A处的剖视图；图4为图3在B处的局部放大图(活动件密封状态)；图5为图3在B处的局部放大图(活动件上浮状态)。
如图1至图3所示，为了解决现有洗衣机存在的泡沫容易通过进水管路外溢的问题，本发明提供了一种滚筒洗衣机(以下或简称洗衣机)，其主要包括机壳(图中未示出)以及设置于机壳内的外筒1、内筒(图中未示出)以及洗涤剂盒组件2，洗涤剂盒组件2具有盒出管21，外筒1上设置有外筒管11，盒出管21通过连接管3(如橡胶管或塑料管等)与外筒管11连接以实现向外筒1和内筒中添加洗涤水的目的。参照图3和图4，盒出管21与连接管3之间还安装有防泡沫外溢单元4，防泡沫外溢单元4包括壳体41、与壳体41连接的进水管壳43、出水管壳44以及设置于壳体41内的活动件42，壳体41具有进水口411和出水口412，进水管壳43与出水管壳44分别与进水口411和出水口412连通， 进水口411处设置有缩径段4111，活动件42在重力的作用下能够卡置于该缩径段4111。
参照图3、图4和图5，滚筒洗衣机在进水阶段，洗涤水通过进水电磁阀进入洗涤剂盒，并依次通过盒出管21、防泡沫外溢单元4、连接管3和外筒管11后，进入洗衣机的外筒1和内筒中。当洗涤水从进水口411流入时，活动件42被洗涤水顶起而上移，从而进水口411与出水口412处于连通状态，洗涤水顺利通过防泡沫外溢单元4；当全部洗涤水从出水口412流出后，活动件42在重力的作用下下落至缩径段4111并将进水口411密封。
通过上述描述可以看出，通过在滚筒洗衣机的盒出管21中设置防泡沫外溢单元4，能够有效防止滚筒洗衣机在运行过程中产生的泡沫沿进水管路回流和外溢的问题，提高滚筒洗衣机的运行安全性。也就是说，本发明有效地解决了现有衣物处理设备存在的泡沫容易通过进水管路外溢的问题，提高了衣物处理设备的安全性和用户体验，并且由于防泡沫外溢单元4结构简单可靠、设计巧妙，因此适宜大规模推广使用。
本领域技术人员能够理解的是，除上述描述的洗衣机各零部件外，滚筒洗衣机显然还包括其他零部件和结构，本实施方式中虽然没有描述，但是这些零部件应当按照现有技术中的滚筒洗衣机所具备的形状和特征进行理解，并且这些形状和特征不应当被看做是对本发明的限制。例如，滚筒洗衣机还可以包括烘干系统、减震装置、驱动电机、传动机构等。
下面参照图4和图5，对本发明的防泡沫外溢单元4进行详细地描述。
如图4和图5所示，防泡沫外溢单元4的壳体41左右两侧分别连接有和出水管壳44和进水管壳43，连接好后形成管中管结构。在一种较为优选地实施方式中，进水管壳43、出水管壳44和壳体41一体成型，进水管壳43和出水管壳44为管状结构，壳体41可以为筒状结构，也可以为箱式结构等。以筒状结构为例，壳体41的下端设置有进水口411，壳体41的左端设置有出水口412，如此一来进水方向(即竖直方向)与出水方向(水平方向)形成大致90°的夹角。进水口411处具有缩径段4111，活动件42优选地为球结构，缩径段4111上设置有与球结构表面 相匹配的内环面4112，以便球结构在重力作用下嵌入该内环面4112中。其中，壳体41沿洗涤水出水方向的长度(即图5中所标示的长度x)略大于球结构的直径，内环面4112设置成远离进水口411的一端所围成的圆形的直径(即图5中所标示的直径d)小于球结构的直径。如此一来，球结构在脱离内环面4112时，能够沿水平方向左右晃动；球结构在嵌入内环面4112中时，球结构的下半部分与缩径段4111之间形成一定的空间。
继续参照图4和图5，出水口412处还设置有用来防止球结构移动出壳体41的限位结构413，如沿筒状壳体41的径向延伸的限位筋。限位筋的末端由出水口412向壳体41内部延伸，形成一定的导向斜面。
上述设置方式的优点在于：通过球结构在洗涤水流入进水口411时被洗涤水顶起，从而进水口411与出水口412连通的设置方式，能够在洗衣机进水过程中保证进水流畅度与进水效率；通过在洗涤水流出出水口412后球结构在重力作用下密封缩径段4111的设置方式，则能够在进水结束后实现对进水管路的完全密封，保证泡沫无法沿进水管路回流和外溢。缩径段4111上设置与球结构匹配的内环面4112，一方面在球结构下落过程中起到导向的作用，另一方面使得球结构嵌入内环面4112时更加稳定，增加了球结构嵌入内环面4112的密封效果，即防泡沫外溢效果。限位筋的末端由出水口412向壳体41内部倾斜的设置方式，能够在球结构被顶起时对球结构进行限位的同时，还有利于球结构地安装，减小安装难度，只需轻轻一按便安装完成。
此外，壳体41沿水平方向的长度大于球结构直径的设置方式，还有利于平衡筒内的压力。当关闭洗衣机门盖时，内筒和外筒1内部的气压瞬间增大，增大的气压可以推动球结构使球结构在壳体41内左右晃动，从而增大的气压沿进水管路外泄，气压平衡后，球结构下落至密封状态，继续防止泡沫外溢。内环面4112上端的圆形的直径小于球结构的直径，使得球结构下半部分与缩径段4111之间形成一定的空间，该空间的形成，有利于气压推动球结构，进而使球结构的晃动更加容易。
需要说明的是，上述实施方式仅仅用来阐述本发明的原理，并非旨在与限制本发明的保护范围，在不偏离本发明原理的条件下，本 领域技术人员能够对上述结构进行调整，以便本发明能够应用于更加具体的应用场景。
例如，在一种可替换的实施方式中，防泡沫外溢单元4还可以设置在连接管3与外筒管11之间，这样的设置方式可以在产生泡沫的第一时间便将泡沫阻隔。
例如，在另一种可替换的实施方式中，防泡沫外溢单元4还可以省略进水管壳43和出水管壳44，转而在相应的盒出管21和连接管3上加工出与进水口411和出水口412相匹配的连接结构，实现防泡沫外溢单元4在进水管路中的安装。
再如，在另一种可以替换的实施方式中，壳体41与进水管壳43和/或出水管壳44之间还可以采用可拆卸连接、粘接等，以便于安装球结构。
再如，在另一种可以替换的实施方式中，壳体41的出水口412处还可以不设置限位筋，转而在出水管壳44与壳体41之间加装过滤网、十字型压盖等代替。
再如，在另一种可以替换的实施方式中，缩径段4111可以不设置任何内环面4112，或者内环面4112可以不与球结构的外表面相匹配，只要球结构下落至缩径段4111后能够密封或堵住进水口411以便有效地防止泡沫外溢即可。
再如，在另一种可以替换的实施方式中，进水口411与出水口412之间的夹角还可以设置为任意角度，只要该角度的设置在球结构被顶起后有利于洗涤水的流动即可；限位结构413的设置数量、形式和设置位置并不唯一，还可以设置多个、形式为条状凸起、设置在出水口412外侧的管壁上等；球结构的材料和形式并不唯一，只要其整体的密度小于洗涤水的密度即可，如球结构还可以为空心球结构或椭圆形球结构等，当然，在满足条件时，也可以使用下端带有导向斜面或导向锥面的活动块或其他形式的活动件代替。
下面参照图4和图5，对防泡沫外溢单元4的工作过程进行描述。
参照图4和图5，在一种可能的实施方式中，洗衣机的进水过程为：水源通过电磁阀进入洗涤剂盒并与洗涤剂盒中的洗涤剂融合成 洗涤水→洗涤水通过盒出管21进入进水管壳43，并流动至壳体41的进水口411处→球结构在洗涤水的推动下被顶开，从而进水口411与出水口412连通，洗涤水通过出水口412，并依次经过出水管壳44、连接管3和外筒管11进入外筒1和内筒→全部洗涤水流出壳体41后，球结构在重力的作用下下落，并在内环面4112的导向下嵌入内环面4112之中，实现对进水管路的密封。
最后需要说明的是，虽然本实施方式中是以滚筒洗衣机为例进行描述的，但本发明的防泡沫外溢单元显然还可以应用于其他衣物处理设备，只要该衣物处理设备具有进水管路并且在运行过程中能够产生泡沫。例如，衣物处理设备还可以是波轮洗衣机、洗鞋机、洗碗机等。
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。
