Description

一种洗衣机的内桶法兰组件及洗衣机 技术领域
本发明属于洗衣机技术领域，具体地说，涉及一种洗衣机的内桶法兰组件及洗衣机。
背景技术
现有洗衣机大多包括相互连通的内桶和外桶，洗衣机在工作时，外桶盛放洗涤水，内桶盛放待洗衣物，洗涤水可以存在于内桶与外桶之间。随着洗衣机工作时间的增长，洗涤水中带有的污垢和线屑会滞留在内桶、外桶之间的空间，且难以清理，导致常年使用产生细菌和异味。为解决这一问题，现有技术提出了一种在内桶上不设置脱水孔的洗衣机，使得内桶在洗涤过程中可以独立盛放洗涤水，但与此同时，现有的排水方式无法实现无孔内桶的排水。
申请号为201610767640.4的中国专利公开了一种内外桶间无水的洗衣机，包括：外桶；内桶，可转动的设置在外桶内；在洗涤/漂洗过程中，所述的内桶内盛水，内桶与外桶之间无水；所述内桶的底部开设排水孔，所述内桶的底部外壁上对应排水孔设置排水密封装置；在洗涤/漂洗时，所述的排水密封装置保持排水孔封闭，在脱水时，所述的排水密封装置在离心力作用下将排水孔打开。
但在上述方案中，阀塞沿内桶的径向滑动以打开/封堵排水孔，受水压的影响，密封效果不理想。同时，受到波轮式洗衣机的转速限制，离心块所能提供的离心力有限，可能出现排水密封装置无法打开排水孔的情况。在内桶下方增加排水密封装置占用了内桶底部的空间，不利于内桶的扩容。
有鉴于此，特提出本发明。

实施例一
本实施例提供一种洗衣机的内桶法兰组件，以及具有所述内桶法兰组件的洗衣机。
如图1至图8所示，所述内桶法兰组件包括法兰本体100，还包括密封塞体200和驱动密封塞体200运动的驱动部件，所述驱动部件包括离心滑块300和换向传动机构。
离心滑块300沿法兰本体100的径向可滑动的安装在法兰本体100上，所述换向传动机构分别与密封塞体200和离心滑块300连接，将离心滑块300沿法兰本体100径向的滑动转换为密封塞体200沿平行于法兰本体100的中心轴线方向的运动。
在上述方案中，密封塞体200和离心滑块300集成在法兰本体100上，结构紧凑，占用空间小，避免了现有技术中离心排水结构在内桶下方占用较大空间的情况，有利于内桶的扩容。如图5至图8所示，内桶法兰组件可作为整体结构可直接安装至洗衣机的内桶下方，通过将法兰本体100与内桶的桶底1固定连接，并将密封塞体200对应安装在排水口2处，即可实现所述内桶法兰组件在洗衣机中的应用。
通过设置换向传动机构，将离心滑块300沿法兰本体100径向的滑动转换为密封塞体200沿平行于法兰本体100的中心轴线方向的运动，使密封塞体200可以沿平行于法兰本体100的中心轴线方向运动封堵排水口2，密封效果更好。
本实施例的进一步方案中，密封塞体200沿平行于法兰本体100的中心轴线方向可滑动的安装在法兰本体100上，密封塞体200的滑动路径与离心滑块300的滑动路径位于同一平面上。
所述换向传动机构包括换向杆401，换向杆401的一端与密封塞体200铰接，另一端可在离心滑块300带动下沿法兰本体100的径向运动。换向杆401在离心滑块300和密封塞体200的滑动路径所构成的平面内摆动，带动密封塞体200沿平行于法兰本体100的中心轴线方向运动。
优选地，密封塞体200与法兰本体100的中心轴线之间的距离小于离心滑块300与法兰 本体100的中心轴线之间的距离。通过将离心滑块300设置在更靠近法兰本体100边缘的位置，增加了离心滑块300与法兰本体100中心轴线的距离，在离心滑块300的质量一定的情况下，由于其转动半径更大，可以在同一转速下提供更大的离心力，避免了离心滑块300无法带动密封塞体200运动的情况。
进一步地，离心滑块300向远离法兰本体100中心轴线的方向运动，带动换向杆401与密封塞体200铰接的一端向远离法兰本体100的方向运动。
所述换向传动机构还包括连接杆402，连接杆402一端与离心滑块300固定连接，另一端与换向杆401远离密封塞体200的一端铰接，带动换向杆401远离密封塞体200的一端沿法兰本体100的径向运动。
优选地，连接杆402与换向杆401连接的一端设置连接部404，连接部404上开设第一销孔，换向杆401与连接杆402连接的一端开设第二销孔，连接销403可转动的插入所述第一销孔和第二销孔中，连接连接杆402与换向杆401。
本实施例中，连接杆402与离心滑块300为一体结构。
在上述方案中，通过铰接连接的换向杆401与连接杆402组成换向传动机构，连接杆402带动换向杆401的一端与离心滑块300同步沿法兰本体100的径向运动，换向杆401另一端可以沿竖直方向上下运动，从而带动密封塞体200沿竖直方向运动。
优选地，连接杆402的上表面为沿法兰本体100径向由内向外高度逐渐增加的内凹曲面。所述内凹曲面用于避让密封塞体200以及排水口2处内桶的桶底1结构，防止连接杆402与内桶的桶底1相互干涉。
本实施例中，如图5至图8所示，法兰本体100与洗衣机的内桶桶底1安装后，密封塞体200从内桶的内部由上至下封堵排水口2。排水时，离心滑块300在离心力的作用下沿法兰本体100径向向外侧滑动，连接杆402同步向外滑动，带动换向杆401下端向外侧运动。换向杆401上端进而在离心滑块300的带动下向上运动，将密封塞体200从排水口2处顶开，打开排水口2。
本实施例的进一步方案中，密封塞体200包括密封盖201和支撑杆202，支撑杆202的一端与密封盖201固定连接，另一端与换向杆401铰接。
进一步地，法兰本体100上固定设置安装座500，安装座500包括固定部501和具有中空滑道的导向部502，所述中空滑道沿平行于法兰本体100的中心轴线方向延伸设置。
固定部501与法兰本体100固定连接，支撑杆202的一端可滑动的设置在导向部502的中空滑道内，另一端伸出导向部502与密封盖201连接。
优选地，密封盖201外周下侧固定设置密封垫203，密封塞体200封堵排水口2时，密封垫203与排水口2的外周密封贴合，从而起到更好的密封效果。
本实施例中，密封塞体200从内桶的内部封堵排水口2，当内桶中盛水时，水压作用在密封盖201的上表面以提供辅助密封力，密封效果更好。导向部502的设置限制了密封塞体200在水平方向上的运动，从而通过换向杆401有效地将离心滑块300的水平运动转换为密封塞体200在竖直方向上的运动。
另一方面，密封塞体200通过密封盖201封堵排水口2，换向杆401的摆动向上顶起密封塞体200以打开排水口2，有效地利用了内桶的桶底1与波轮之间的空间，使排水口2被打开后的开口高度可以达到12mm，能够有效地将纽扣、发夹、硬币、线屑等洗涤异物排出。
进一步地，支撑杆202的下端具有敞口的安装槽，换向杆401的上端插入所述安装槽中与支撑杆202铰接。导向部502的下端具有沿法兰本体100径向贯通的避让槽503，换向杆401上端与支撑杆202下端在导向部502内部铰接，换向杆401的下半部分在密封塞体200封堵排水口2时穿过避让槽503伸出导向部502。
本实施例的另一种方案中，还可以通过调整密封塞体和换向杆的相对位置关系，使密封塞体从内桶外部由下至上封堵排水口。当离心滑块在离心力的作用下沿法兰本体径向向外侧滑动时，通过连接杆带动换向杆摆动，使换向杆一端沿法兰本体径向向外运动，另一端竖直向下运动，从而拉动密封塞体向下打开排水口。
本实施例的进一步方案中，所述离心滑块300为与法兰本体100的中心轴线垂直的板状结构，离心滑块300靠近法兰本体100中心轴线的一侧具有内凹的避让口301，避让口301具有弧形边缘，所述弧形边缘的半径大于排水口2的半径。
离心滑块300具有如图5和图6所示的靠近法兰本体100中心轴线的第一位置，以及如图7和图8所示的相对远离法兰本体100中心轴线的第二位置。离心滑块300处于第一位置时，密封塞体200封堵排水口2，离心滑块300滑动至第二位置时，密封塞体200被向上顶开打开排水口2。当离心滑块300处于第一位置时，避让口301的弧形边缘的圆心重合至密封塞体200的滑动路径上。
对于波轮洗衣机而言，受其所能达到的最高转速的限制，为通过离心滑块300提供足够打开排水口2的离心力，需要加大离心滑块300的质量，也即需要更大体积的离心滑块300。在上述方案中，板状结构的离心滑块300可以贴合安装在法兰本体100上，或者从法兰本体100的外周向内部开设与离心滑块300的形状匹配的安装口进行安装，而不额外占用法兰本体100下方的空间，整体结构紧凑，占用空间小。
避让口301的设置确保了排水口2打开时，离心滑块300不遮挡排水口2下方的空间，排水过程更加顺畅。另一方面，为实现与密封塞体200更好的配合，桶底1在排水口2外周处向内桶下方凸起设置，通过设置避让口301实现了离心滑块300处于第一位置时对排水口2处桶底1凸起的避让。
本实施例的进一步方案中，法兰本体100上固定安装导向轨道600，离心滑块300可滑动的设置在所述导向轨道600上。
优选地，法兰本体100的边缘具有内凹的安装口，导向轨道600平行设置两个，分别固定安装在所述安装口的两侧，离心滑块300设置在两个导向轨道600之间。
具体地，如图4所示，导向轨道600上开设导向槽603，离心滑块300的两侧分别设置安装部302，安装部302可滑动的设置在导向槽603内。离心滑块300上还设置第一限位部303，导向轨道600上设置第二限位部604，所述第一限位部303和第二限位部604具有相对的表面，防止离心滑块300向法兰本体100外侧滑动时从导向轨道600上脱出。
进一步地，导向轨道600上还安装弹性件，所述弹性件用于向离心滑块300提供与离心 力方向相反的复位力。
优选地，导向轨道600包括沿离心滑块300滑动方向延伸设置的导向杆601，离心滑块300上设置定位孔，导向杆601插入所述定位孔中。所述弹性件为套设在导向杆601上的弹簧602，弹簧602的两端分别与离心滑块300和导向轨道600的表面相抵。
具体地，导向杆601一端固定在第二限位部604朝向第一限位部303的表面上，另一端悬空设置。定位孔贯通设置在离心滑块300的第一限位部303上，导向杆601的悬空端插入所述定位孔中。弹簧602套设在导向杆601上，两端分别与第一限位部303和第二限位部604相抵。
排水时，内桶以一定转速转动，离心滑块300在离心力作用下克服弹簧602的弹力向法兰本体100的外侧方向滑动，进而带动密封塞体200打开排水口2。内桶转速下降直至停止转动的过程中，离心力逐渐减小，当离心滑块300所受离心力小于弹簧602的弹力时，弹簧602向法兰本体100内侧推动第一限位部303，使离心滑块300向法兰本体100内侧滑动，带动密封塞体200封堵排水口2。
本实施例中，密封塞体200和离心滑块300集成设置在法兰本体100上，应用于洗衣机中时，可作为一个整体结构直接安装在内桶下方，结构紧凑，占用空间小。通过设置换向传动机构，沿法兰本体100径向方向滑动的离心滑块300可以带动密封塞体200沿平行于法兰本体100中心轴线的方向运动，实现了从竖直方向上封堵排水口2，密封效果好。
如图5至图8所示，本实施例所述的洗衣机包括内桶和上述所述的内桶法兰组件。所述法兰本体100与内桶的桶底1同轴设置，固定安装在内桶的桶底1上。所述内桶的桶底1上开设排水口2。
洗涤/漂洗过程中，所述密封塞体200封堵排水口2，使内桶在洗涤/漂洗过程中独立盛水。
排水过程中，离心滑块300在离心力作用下沿法兰本体100的径向滑动，通过换向传动机构带动密封塞体200沿平行于法兰本体100的中心轴线方向运动以打开排水口2。
本实施例中，内桶的桶壁上不设置脱水孔，在洗涤/漂洗过程中，通过密封塞体200封堵排水口2形成封闭内桶，从而实现洗涤/漂洗过程中内桶独立盛水。洗衣机中可以不设置外桶，从而实现内桶的扩容。当内桶外设置外桶时，由于在洗涤/漂洗过程中内桶独立盛水，内、外桶间不存水，一方面节省了洗涤/漂洗水的用量，另一方面避免了内、外桶间污垢和线屑的残留，更加卫生。
内桶的排水通过集成在法兰本体100上的密封塞体200和离心滑块300实现。具体地，洗涤/漂洗过程中，内桶为自由状态，密封塞体200封堵排水口2。排水时，控制内桶以一定转速转动，从而产生足够的离心力使离心滑块300滑动，离心滑块300在离心力作用下沿法兰本体100径向向外滑动，带动密封塞体200运动打开排水口2，实现排水功能。
本实施例中，内桶可以在洗涤/漂洗过程中独立盛水，通过集成在法兰本体100上的排水阀组件实现内桶的排水功能，采用纯机械结构完成内桶的排水，省去了现有技术中为实现内桶的排水单独设置的驱动电机，降低了成本，同时不需要在排水前对内桶进行定位，控制更加简单。排水阀组件集成在法兰本体100上，结构紧凑，占用空间小，有利于洗衣机内桶的扩容。
实施例二
本实施例提供一种洗衣机的内桶法兰组件，以及具有所述内桶法兰组件的洗衣机。
如图9至图16所示，内桶法兰组件包括法兰本体100和设置在法兰本体100上密封塞体200、驱动部件，所述驱动部件包括离心滑块300。离心滑块300具有驱动面321，离心滑块300沿法兰本体100的径向滑动，密封塞体200与驱动面321接触配合随之运动。
在上述方案中，密封塞体200与离心滑块300集成设置在法兰本体100上，结构紧凑，占用空间小，避免了现有技术中离心排水结构在内桶下方占用较大空间的情况，有利于内桶的扩容。内桶法兰组件作为整体结构可直接安装至洗衣机的内桶下方，通过将法兰本体100与内桶的桶底1固定连接，并将密封塞体200对应安装在排水口2处，实现本实施例的内桶法兰组件在洗衣机中的应用。
本实施例的进一步方案中，离心滑块300包括支撑部320和离心部310，驱动面321为设置在支撑部320上沿法兰本体100径向由内向外高度逐渐降低的倾斜支撑面。
离心滑块300沿法兰本体100径向由内向外滑动，驱动面321推动密封塞体200向上运动。
在上述方案中，通过设置倾斜支撑面作为驱动面321与密封塞体200接触配合，使离心滑块300沿法兰本体100的径向滑动时，密封塞体200可以随驱动面321在竖直方向上运动，结构简单，易于实现。如图5至图8所示，离心滑块300在离心力作用下向外滑动时，驱动面321向上推动密封塞体200以打开排水口2。离心滑块300向内滑动复位时，密封塞体200在重力作用下沿驱动面321回落，从内桶内部由上至下封堵排水口2。
本实施例的另一种方案中，驱动面也可以为设置在支撑部上沿法兰本体径向由内向外高度逐渐增加的倾斜支撑面。离心滑块沿法兰本体径向由内向外滑动，密封塞体沿驱动面向下运动。
在上述方案中，密封塞体设置在内桶下方，从内桶外部自下至上封堵排水口。当离心滑块在离心力作用下向外滑动时，密封塞体在重力作用下沿驱动面下降打开排水口。离心滑块向内滑动复位时，驱动面向上推动密封塞体，从内桶外部封堵排水口。
本实施例的优选方案中，密封塞体200具有与驱动面321同向倾斜的配合面204，配合面204与驱动面321可相对滑动的贴合设置。
在上述方案中，通过设置与驱动面321滑动贴合的配合面204，使密封塞体200与离心滑块300的支撑部320之间的接触为面接触，支撑部320对密封塞体200的支撑更加稳定。
本实施例的进一步方案中，支撑部320设置在密封塞体200的下方，离心部310设置在密封塞体200沿法兰本体100径向的外侧，离心滑块300还包括连接支撑部320和离心部310的过渡部330。
在上述方案中，离心滑块300的质量主要集中在离心部310上，由离心部310提供带动离心滑块300滑动的离心力。在法兰本体100的径向上，离心部310相对密封塞体200更靠近法兰本体100的外周，增加了离心部310与法兰本体100中心轴线的距离，在离心部310的质量一定的情况下，由于其转动半径更大，可以在同一转速下提供更大的离心力，避免了离心滑块300无法带动密封塞体200运动的情况。
进一步地，离心部310为与法兰本体100的中心轴线垂直的板状结构，过渡部330从离心部310上沿法兰本体100径向延伸连接至支撑部320。支撑部320从过渡部330的端部向上延伸形成与密封塞体200接触配合的驱动面321。
对于波轮洗衣机而言，受其所能达到的最高转速的限制，为通过离心滑块300提供足够打开排水口2的离心力，需要加大离心部310的质量，也即需要增加离心部310的体积。在上述方案中，将离心部310设计为板状结构，使其可以贴合安装在法兰本体100上，或者从法兰本体100的外周向内部开设与离心部310的形状匹配的安装口进行安装，而不额外占用法兰本体100下方的空间，整体结构紧凑，占用空间小。
支撑部320设置在过渡部330靠近法兰本体100中心轴线的一端，竖直向上延伸，顶端形成倾斜的驱动面321，可以更好地和设置在上方的密封塞体200配合。
优选地，过渡部330的上表面为沿法兰本体100径向由内向外高度逐渐增加的内凹曲面。所述内凹曲面用于避让密封塞体200以及排水口2处内桶的桶底1结构，防止离心滑块300与内桶的桶底1相互干涉。
本实施例中采用密封塞体200从内桶内部自上至下封堵排水口2的结构。
具体地，密封塞体200包括密封盖201和支撑杆202，支撑杆202的一端与密封盖201固定连接，另一端与驱动面321接触配合。
支撑杆202与驱动面321接触配合的一端具有与驱动面321可相对滑动的贴合设置的配合面204。
进一步地，法兰本体100上固定设置安装座500，安装座500包括固定部501和具有中空滑道的导向部502，所述中空滑道沿平行于法兰本体100的中心轴线方向延伸设置。
固定部501与法兰本体100固定连接，导向部502可相对滑动的套设在支撑杆202上。离心滑块300的支撑部320从导向部502下端伸入所述中空滑道中，驱动面321设置在支撑部320的上端，与支撑杆202的下端接触配合。
优选地，密封盖201外周下侧固定设置密封垫203，密封塞体200封堵排水口2时，密封垫203与排水口2的外周密封贴合，从而起到更好的密封效果。
本实施例的内桶法兰组件安装时，密封盖201设置在内桶内部，支撑杆202从排水口2穿出与下方的支撑部320接触配合。密封塞体200从内桶的内部封堵排水口2，当内桶中盛水时，水压作用在密封盖201的上表面以提供辅助密封力，密封效果更好。导向部502的设置限制了密封塞体200在水平方向上的运动，确保了密封塞体200沿驱动面321竖直运动打开/封堵排水口2。
如图13至图16所示，本实施例中，法兰本体100与洗衣机的内桶桶底1安装后，密封塞体200从内桶的内部由上至下封堵排水口2。排水时，离心滑块300在离心力的作用下沿法兰本体100径向向外侧滑动，驱动面321向上推动支撑杆202的下端，将密封塞体200从排水口2处顶开，打开排水口2。
另一方面，密封塞体200通过密封盖201封堵排水口2，驱动面321向上推动密封塞体200以打开排水口2，有效地利用了内桶的桶底1与波轮之间的空间，使排水口2被打开后的开口高度可以达到12mm，能够有效地将纽扣、发夹、硬币、线屑等洗涤异物排出。
本实施例的进一步方案中，离心部310靠近法兰本体100中心轴线的一侧具有内凹的避让口301，避让口301具有弧形边缘，所述弧形边缘的半径大于排水口2的半径。
离心部310具有如图13和图14所示的靠近法兰本体100中心轴线的第一位置，以及如图15和图16所示的相对远离法兰本体100中心轴线的第二位置。离心部310处于第一位置时，密封塞体200封堵排水口2，离心部310滑动至第二位置时，密封塞体200被向上推动打开排水口2。当离心滑块300处于第一位置时，避让口301的弧形边缘的圆心位于支撑杆202下方。
本实施例中，避让口301的设置确保了排水口2打开时，离心滑块300不遮挡排水口2下方的空间，排水过程更加顺畅。另一方面，为实现与密封塞体200更好的配合，桶底1在排水口2外周处向内桶下方凸起设置，通过设置避让口301实现了离心部310处于第一位置时对排水口2处桶底1凸起的避让。
本实施例中，离心滑块300与法兰本体100的具体安装结构如下。
法兰本体100上固定安装导向轨道600，离心滑块300的离心部310可滑动的设置在所述导向轨道600上。
优选地，法兰本体100的边缘具有内凹的安装口，导向轨道600平行设置两个，分别固定安装在所述安装口的两侧，离心部310设置在两个导向轨道600之间。
具体地，如图12所示，导向轨道600上开设导向槽603，离心部310的两侧分别设置安装部302，安装部302可滑动的设置在导向槽603内。离心部310上还设置第一限位部303，导向轨道600上设置第二限位部604，第一限位部303和第二限位部604具有相对的表面，防止离心滑块300向法兰本体100外侧滑动时离心部310从导向轨道600上脱出。
进一步地，导向轨道600上还安装弹性件，所述弹性件用于向离心滑块300提供与离心力方向相反的复位力。
优选地，导向轨道600包括沿离心滑块300滑动方向延伸设置的导向杆601，离心部310上设置定位孔，导向杆601插入所述定位孔中。所述弹性件为套设在导向杆601上的弹簧602，弹簧602的两端分别与离心部310和导向轨道600的表面相抵。
具体地，导向杆601一端固定在第二限位部604朝向第一限位部303的表面上，另一端悬空设置。定位孔贯通设置在离心滑块300的第一限位部303上，导向杆601的悬空端插入所述定位孔中。弹簧602套设在导向杆601上，两端分别与第一限位部303和第二限位部604相抵。
排水时，内桶以一定转速转动，离心滑块300在离心力作用下克服弹簧602的弹力向法兰本体100的外侧方向滑动，进而通过驱动面321推动密封塞体200打开排水口2。内桶转速下降直至停止转动的过程中，离心力逐渐减小，当离心滑块300所受离心力小于弹簧602的弹力时，弹簧602向法兰本体100内侧推动第一限位部303，使离心滑块300向法兰本体100内侧滑动，密封塞体200沿驱动面321下落封堵排水口2。
本实施例中，密封塞体200和离心滑块300集成设置在法兰本体100上，应用于洗衣机中时，可作为一个整体结构直接安装在内桶下方，结构紧凑，占用空间小。离心滑块300的结构设计与法兰本体100相配合，可以在增加离心部310质量的情况下不额外占用内桶下方 的空间，整体结构更加紧凑，同时还可以适应波轮洗衣机所能达到的最大转速，提供足够的离心力以打开排水口2。
如图13至图16所示，本实施例所述的洗衣机包括内桶和上述所述的内桶法兰组件。法兰本体100与内桶的桶底1同轴设置，固定安装在内桶的桶底1上。所述内桶的桶底1上开设排水口2。
洗涤/漂洗过程中，密封塞体200封堵排水口2，使内桶在洗涤/漂洗过程中独立盛水。
排水过程中，离心滑块300在离心力作用下沿法兰本体100的径向滑动，密封塞体200与驱动面321接触配合随之运动以打开排水口2。
本实施例中，内桶的桶壁上不设置脱水孔，在洗涤/漂洗过程中，通过密封塞体200封堵排水口2形成封闭内桶，从而实现洗涤/漂洗过程中内桶独立盛水。洗衣机中可以不设置外桶，从而实现内桶的扩容。当内桶外设置外桶时，由于在洗涤/漂洗过程中内桶独立盛水，内、外桶间不存水，一方面节省了洗涤/漂洗水的用量，另一方面避免了内、外桶间污垢和线屑的残留，更加卫生。
内桶的排水通过集成在法兰本体100上的排水阀组件实现。具体地，洗涤/漂洗过程中，内桶为自由状态，密封塞体200封堵排水口2。排水时，控制内桶以一定转速转动，从而产生足够的离心力使离心滑块300滑动，离心滑块300在离心力作用下沿法兰本体100径向向外滑动，密封塞体200随驱动面321运动打开排水口2，实现排水功能。
本实施例中，内桶可以在洗涤/漂洗过程中独立盛水，通过集成在法兰本体100上的密封塞体200和离心滑块300实现内桶的排水功能，采用纯机械结构完成内桶的排水，省去了现有技术中为实现内桶的排水单独设置的驱动电机，降低了成本，同时不需要在排水前对内桶进行定位，控制更加简单。密封塞体200和离心滑块300集成在法兰本体100上，结构紧凑，占用空间小，有利于洗衣机内桶的扩容。
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。
