Description
本发明属于洗衣机领域，具体地说，涉及一种免清洗洗衣机的排水阀及洗衣机。
现有的洗衣机内、外桶之间是一个封闭的环境，只有水流可以通过，由于洗衣机上述结构的局限性和使用环境的特殊性，因此在使用3-5个月之后，内桶外壁和外桶内壁上会粘附污垢，从而滋生不同程度的细菌，而滋生的细菌绝大部分是对人体有害的。
通过在洗衣机内桶、外桶之间的硅胶球、柔性颗粒等方式，通过硅胶球和柔性颗粒运动并不断碰撞内外桶的两壁以达到清洁内外桶壁的目的。
专利CN201510013177.X提供了一种洗衣机排水装置、洗衣机及控制方法，该洗衣机内外桶之间设有清洁桶壁的清洗颗粒，排水装置在排水时收集清洗颗粒至颗粒盛放腔室内，进水时受水的浮力从进水口上浮至洗衣机内外桶之间。排水装置包括排水阀本体、进水口和出水口，进水口与洗衣机外桶排水口连通，排水阀本体内设有与进水口相通的颗粒盛放腔室，颗粒盛放腔室和出水口之间设有颗粒过滤结构，该排水装置还包括向颗粒盛放腔室进水的水泵机构。当颗粒盛放腔室内的清洗颗粒和线屑缠绕成团导致排水不畅时，由水泵机构控制进水至颗粒盛放腔室冲散线屑团以顺利排水。排水装置使得投放清洗颗粒能够全部上浮，投放更快速；且使得排水时线屑能够完全排出，不造成排水堵塞。
虽然上述结构解决了清洗颗粒的上浮和防堵塞问题，但是在转速提升到一定程度，衣物偏重达到一定程度后，在洗衣机脱水运转后期过程中容易出现清洁球由于收集仓的碰撞反弹作用被弹回到内外桶之间出现较大的噪音，同时由于高速转动的内桶对清洁球的高速摩擦作用，容易对清洁球表面造成损伤，从而降低清洁球的使用寿命或者降低清洁效果。
有鉴于此特提出本发明。
发明内容
本发明要解决的技术问题在于克服现有技术的不足，提供一种免清洗洗衣机的排水阀及洗衣机，通过在排水阀的颗粒收放腔室内设置一个留水腔室，在脱水过程中，留水腔室内的水可对清洗颗粒产生粘滞作用以释放高速脱水带来的摩擦和碰撞能量，从而避免由此带来的噪音或者磨损问题。
为解决上述技术问题，本发明采用技术方案的基本构思是：
一种免清洗洗衣机的排水阀，包括排水阀本体、进水口和出水口，所述进水口与洗衣机的外桶排水口连通，排水阀本体内设有与进水口连通的颗粒收放腔室，所述颗粒收放腔室内具有一在排水完成后存水的留水腔室。
通过在颗粒收放腔室内设置留水腔室，在脱水过程中，尤其是当脱水进行到后期，留水腔室内的水可对清洗颗粒产生粘滞作用以释放高速脱水带来的摩擦和碰撞能量，从而避免由此带来的噪音或者磨损问题。
所述排水阀本体内还设有用于安装阀塞的排水腔室，所述排水腔室分别与出水口和颗粒收放腔室连通，所述排水腔室与所述颗粒收放腔室相连通的连通口高于留水腔室。
通过将连通口设置的高于留水腔室,当脱水进行到后期时,能够在留水腔室内存留一定的水量,使该部分水可对清洗颗粒产生粘滞作用以释放高速脱水带来的摩擦和碰撞能量，从而避免由此带来的噪音或者磨损。
所述颗粒收放腔室的底壁低于所述连通口形成留水腔室。
由于所述颗粒收放腔室的底壁低于连通口，在脱水过程中，颗粒收放腔室的底部能够存留一部分水，进而形成了留水腔室。该方式结构简单，余水存留量大，但是该结构在转速提升到一定程度，衣物偏重达到一定程度后，尤其是在洗衣机脱水运转后期时，容易出现清洗颗粒由于颗粒收放腔室的碰撞反弹作用被弹回到内桶和外桶之间，出现较大的噪音。
所述颗粒收放腔室的底壁部分向所述颗粒收放腔室外壁凸出形成留水腔室。
通过使颗粒收放腔室的底壁部分向所述颗粒收放腔室外壁凸出形成留水腔室，该留水腔室进一步扩大了存留的余水量，可增加存留的清洗颗粒的数量，也能提高粘滞效果。
所述留水腔室具有与所述颗粒收放腔室连通的留水腔室进水口，所述留水腔室进水口与排水阀的所述进水口错位设置。
由于在转速提升到一定程度，衣物偏重达到一定程度后，在洗衣机脱水运转后期过程中，容易出现清洗颗粒由于颗粒收放腔室的碰撞反弹作用被弹回到洗衣机的内桶和外桶之间，出现较大的噪音，通过将进水口与所述留水腔室进水口错位设置，使得即使清洗颗粒之间碰撞发生反弹，也不易直接弹回洗衣机的内桶和外桶之间。
所述进水口设置于所述颗粒收放腔室的顶壁，所述进水口与所述留水腔室进水口在水平方向上间隔一定距离设置；
或者，所述进水口与所述留水腔室进水口部分重合，所述重合部分的最大间距D小于清
洗颗粒的直径。
通过将进水口设置在颗粒收放腔室的顶壁上，进水口与留水腔室进水口在竖直方向间隔的距离最大，使清洗颗粒不易弹回内、外桶之间，进一步地，将进水口与所述留水腔室进水口在水平方向上间隔一定距离设置，使清洗颗粒即使被弹起，也不易弹回内外桶之间。即使存在部分重合的现象，所述重合部分的最大间距小于清洗颗粒的直径，清洗颗粒也不易进入颗粒收放腔室内。
所述留水腔室具有与所述颗粒收放腔室的底壁过渡连接的连接壁；
优选地，所述连接壁与颗粒收放腔室的底壁的夹角大于90°。
留水腔室具有与所述颗粒收放腔室的底壁过渡连接的连接壁，使颗粒收放腔室的底壁与连接壁过渡连接，使清洗颗粒更容易进、出留水腔室；
所述连接壁倾斜设置并且连接壁与颗粒收放腔室的底壁的夹角大于90°，使留水量更大，更加方便清洗颗粒更容易进、出留水腔室。
所述颗粒收放腔室的底壁由边缘向所述留水腔室进水口倾斜设置且边缘高于留水腔室进水口。
所述颗粒收放腔室的底壁由边缘向所述留水腔室进水口倾斜设置且边缘高于留水腔室进水口，可以使水更容易汇集到留水腔室内，同时斜面的导向作用，使清洗颗粒更容易浮起，进入内桶和外桶之间。
还包括用于将留水腔室内的留水缓慢排出的缓流装置，所述缓流装置的进水端与所述留水腔室连通，出水端与出水口连通，使留水腔室内的存水在脱水后完全排出。
通过设置缓流装置，使留水腔室内的存水在洗衣结束后缓慢排出，防止细菌滋生。
设置有上述的排水阀的洗衣机，包括外桶和内桶，所述外桶和内桶之间设有清洗颗粒，在排水时，清洗颗粒进入颗粒收放腔室，在排水完成后，留水腔室内留有在脱水过程中吸附清洗颗粒的存水。
采用上述技术方案后，本发明与现有技术相比具有以下有益效果：通过在颗粒收放腔室内设置留水腔室，在脱水过程中，尤其是当脱水进行到后期，留水腔室内的水可对清洗颗粒产生粘滞作用以释放高速脱水带来的摩擦和碰撞能量，从而避免由此带来的噪音或者磨损问题；通过使颗粒收放腔室的底壁部分向所述颗粒收放腔室外壁凸出形成留水腔室，该留水腔室进一步扩大了存留的余水量，可增加存留的清洗颗粒的数量，也能提高粘滞效果；通过将进水口与所述留水腔室进水口错位设置，使得即使清洗颗粒之间碰撞发生反弹，也不易直接
弹回洗衣机的内桶和外桶之间。

如图1-图3所示，一种免清洗洗衣机的排水阀，洗衣机包括内桶100和外桶101，内桶100和外桶101之间设有清洗颗粒104，所述的排水阀包括排水阀本体、进水口107和出水口106，所述进水口107与洗衣机的外桶101的排水口连通，排水阀本体内设有与进水口107相连通的颗粒收放腔室103，颗粒收放腔室103和出水口106之间设有颗粒过滤结构109，所述颗粒收放腔室103内具有一在排水完成后用于保存余水的留水腔室200。当排水时，留水腔室200内充水，当脱水程序进行时，清洗颗粒104进入颗粒收放腔室103，同时机器开始脱水，清洗颗粒104在留水腔室200内聚集，当脱水进行到后期，留水腔室200内的存水可对清洗颗粒104产生粘滞作用以释放高速脱水带来的摩擦和碰撞能量，从而避免由此带来的噪
音或者磨损问题。
所述排水阀本体内还设有用于安装阀塞的排水腔室102，所述排水腔室102分别与出水口106和颗粒收放腔室103连通，所述排水腔室102与所述颗粒收放腔室103相连通的连通口108高于留水腔室200。留水腔室200具有一个留水腔室进水口，连通口108高于留水腔室进水口202，保证了排水后留水腔室200内能够留有一定的水量，对清洗颗粒104产生粘滞作用。
实施例二：
如图1-图3所示，在实施例一的基础上本实施例为所述颗粒收放腔室103的底壁110部分向所述颗粒收放腔室103外壁凸出形成留水腔室200。该结构存水量大，当清洗颗粒104较多时，也能实现存水对清洗颗粒104的粘滞效果。
进一步地，所述留水腔室200具有与所述颗粒收放腔室103连通的留水腔室进水口202，所述留水腔室进水口202与排水阀的所述进水口107错位设置。
由于在转速提升到一定程度，衣物偏重达到一定程度后，在洗衣机脱水运转后期过程中，清洗颗粒104容易被弹回到内桶100和外桶101之间，加之洗衣机桶在高速转动，容易产生较大的噪音。通过将留水腔室进水口202与排水阀的所述进水口107错位设置，即使清洗颗粒104被弹起，也不易直接进入洗衣机的内桶100和外桶101之间，减少清洗颗粒104被弹回内桶100和外桶101之间的概率，减少产生噪音的可能。
进一步地，所述进水口107设置于所述颗粒收放腔室103的顶壁111上，排水阀的进水口107与所述留水腔室进水口202在水平方向上间隔一定距离设置，使留水腔室进水口202与排水阀的进水口107完全错开。即使由于转速提升等原因使清洗颗粒104被弹起，由于进水口107与留水腔室进水口202错位，也不易使清洗颗粒104被弹回到洗衣机的内桶100和外桶101之间，进一步降低了噪音的产生。
另一种方案为，所述进水口107与所述留水腔室进水口202在水平方向上部分重合，所述重合部分的最大间距D小于清洗颗粒104的直径，使得清洗颗粒104不易从重合部分穿过。
所述留水腔室200具有与所述颗粒收放腔室103的底壁110过渡连接的连接壁201；通过底壁110与连接壁201过渡连接，当颗粒收放腔室103内充水后，清洗颗粒104在水的浮力作用下从留水腔室200内浮出，由于连接壁201与底壁110过渡连接，使清洗颗粒104更容易通过连接壁201进入或者从留水腔室200浮出。
所述连接壁201与颗粒收放腔室103的底壁110的具有一定的夹角θ。
连接壁201与颗粒收放腔室103的底壁110之间夹角θ≤90°，该结构可以存留更多的水，但是当颗粒收放腔室103充水后，该结构使清洗颗粒104不易从留水腔室200内浮出。
连接壁201最好向留水腔室200内倾斜，使连接壁201与所述颗粒收放腔室103的底壁110的夹角θ＞90°，方便清洗颗粒104从留水腔室200内浮出。
进一步地，所述颗粒收放腔室103的底壁110由边缘向所述留水腔室进水口202倾斜设置且边缘高于留水腔室进水口202，即底壁110向所述留水腔室进水口202的方向下倾，使底壁110形成漏斗形，使水更优先的向留水腔室200内汇集，更利于存留水。
留水腔室200也可以是下述方式形成:所述颗粒收放腔室103的底壁110低于所述连通口108形成留水腔室200，由于颗粒收放腔室103的底壁110低于连通口108，在排水时，即在颗粒收放腔室103的底部形成一个留水区域，即为留水腔室200，该结构使留水腔室200存水量大，在脱水过程中留水腔室200内的留水对清洗颗粒104可以产生粘滞作用，减少清洗颗粒104被弹回内桶和外桶101之间的可能，同时使清洗颗粒104之间的碰撞和摩擦减少，降低了对清洗颗粒104的损坏。
实施例三：
如图4所示，在实施例一和实施例二的基础上，本实施例的排水阀还包括用于将留水腔室200内的留水缓慢排出的缓流装置，所述缓流装置的进水端与所述留水腔室200连通，出水端与出水口106连通，使留水腔室200内的存水在脱水后完全排出。
缓流装置包括缓流管300和控制装置，所述缓流管300的进水端与所述留水腔室200连通，出水端与出水口106连通，缓流管300将留水腔室200和出水口106直接连通，在脱水过程中或者脱水结束后，通过控制装置控制留水腔室200内的存水在脱水后完全排出。
控制装置可以是设置在缓流管300内的节流板301，节流板301上开设节流孔，节流孔孔径较小，使节流孔将留水腔室200内的留水完全排净的时间至少为一个脱水时间，使存水在脱水结束后，能够缓慢排出，而又不影响留水腔室200进行存水。由于节流孔的孔径较小，不会影响留水腔室200内的存水，既能留水对清洗颗粒104的粘滞作用，又能防止留水腔室200内长期存水，滋生细菌。
节流板301可以设置在缓流管300的进水端口，也可以设置在出水端口，也可以设置在缓流管300中部。
缓流管300分别与留水腔室200和出水口106螺纹连接或插接。
控制装置也可以为设置在缓流管300上设置控制阀，当脱水完毕后，将控制阀打开，使
留水腔室200内的留水排出。
控制阀可以为手动启闭的截止阀或者止水夹或者为电磁阀，电磁阀与洗衣机的控制器电连接。
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。
