Description

一种波轮洗衣机及控制方法 技术领域
本发明属于洗衣机领域，具体地说，涉及一种波轮洗衣机及控制方法。
背景技术
在波轮洗衣机洗衣过程中，被洗涤物浸没于洗涤水中，依靠波轮连续转动或定时正反向转动的方式进行洗涤。现有波轮洗衣机，一般由外桶盖、箱体、外桶、内桶组成，在箱体和外桶、外桶和内桶之间均会存在间隙。由于内桶桶身有孔，洗涤衣物的脏水会进入外桶和内桶之间的间隙，长期积累会导致洗衣机存在藏污纳垢问题。
鉴于以上问题，为解决藏污纳垢问题，已有技术将外桶简化为接水盘，内桶做成无孔内桶，洗涤时只在内桶内部有水，从而解决了内外桶之间的藏污纳垢问题。同时，由于外桶简化为接水盘，内桶和箱体之间的间隙较大，就可以实现将内桶的尺寸放大，从而洗涤更多衣物。
但是这种无孔内桶的洗衣机，因水只存在于内桶之中，洗涤时由于衣物的阻碍，上下层的水缺少循环，从而造成洗涤液分布不均并进而造成洗涤效果参差不齐。而且，由于只有底部波轮搅动洗衣，如羽绒服等悬浮衣物难以浸透。因此，针对这种无孔内桶，需要解决无外桶洗衣机水流循环的问题。
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，提供一种波轮洗衣机及控制方法，本发明通过在无孔内桶的外壁上设置循环水道，既可以避免在内桶内壁上设置水道，增大内桶的容纳体积，增加用户单次洗涤衣物的数量，还可以实现水流从上部的喷水口喷射到内桶中，喷射力度大，可以喷淋到羽绒服等悬浮力大、漂浮高度较高的衣物上，也可以增强对各种衣物的洗涤效果。

实施例一
如图1-4所示，本实施例提供一种波轮洗衣机，包括内桶1，内桶1包括内桶底2，内桶 底2中设置有波轮3，在洗涤/漂洗时所述的内桶1为盛水桶，内桶1的外壁上设有循环水道200，循环水道200的两端分别与内桶底2和内桶1上部连通，波轮3转动时，推动底部水流进入循环水道200并向上爬升，喷射至内桶1中，形成循环水流。
现有的普通波轮洗衣机中，为了增加水循环效果，采用在内桶1内壁上设置水道的方式，不仅会缩小内桶1的有效容纳空间，减少用户单次可洗涤的衣物数量，同时水道可以设置的高度有限，无法达到从内桶1口处向下喷淋的效果。对于部分悬浮力大的衣物如羽绒服等，水流无法达到从上向下喷射到衣物上洗涤的效果。
本实施例的内桶1为无孔内桶1，洗涤时只在内桶1内部有水，内桶1为盛水桶。通过在无孔内桶1的外壁上设置循环水道200，循环水道200将内桶1的上部与底部连通，在波轮3高速转动时催动水流进入循环水道200，喷射回内桶1，实现喷淋并形成循环水流。如此，既可以避免或者减少在内桶1内壁上设置水道，增大内桶1的容纳体积，增加用户单次洗涤衣物的数量，还可以实现无孔内桶1中上下层水流循环，水流从上部的喷水口201喷射到内桶1中，喷射力度大，可以喷淋到羽绒服等悬浮力大、漂浮高度较高的衣物上，也可以增强对各种衣物的洗涤效果。
进一步的方案，所述的内桶底2上设置有导流通道4，内桶1的上部设置有喷水口201，所述的循环水道200的下端与导流通道4连接，循环水道200的上端与喷水口201连接。
导流通道4为开设在内桶底2上的开孔，由于内桶1具有一定的厚度，该开孔具有一定的长度形成允许水流通过的通道，因此本发明中称之为导流通道4。喷水口201开设在内桶1的上部，高度可以根据需要设定，例如可以开设在内桶1上部收缩压型的下方。如此，循环水道200将内桶1的底部与上部连通，当波轮3高速运转时，可以催动内桶底2部的水流经过导流通道4、循环水道200、喷水口201喷射进入内桶1中，对衣物进行喷淋。
导流通道4和喷水口201可以上下成对的对应设置，也可以一个对应多个设置。优选的方案，一个导流通道4与多个喷水口201对应，循环水道200中的水经过多个喷水口201喷射进内桶1中，以便增强喷淋效果。
进一步的方案，所述的导流通道4位于波轮3外围的内桶底2上，且横向贯通设置；所述的导流通道4的进水口41朝向波轮3，导流通道4的出水口42朝向循环水道200，连通内桶1和循环水道200。
导流通道4设置在波轮3外围的内桶底2上，也就是设置在波轮3外周相对的内桶底2的侧壁上，有利于水流顺畅地通过导流通道4进入循环水道200，使水流有足够的动力沿着 循环水道200向上爬升。
目前的波轮3以竖直方向的轴为中心，在水平方向上沿着顺时针或者逆时针方向旋转，因此带动水流在水平方向上向外甩出。导流通道4横向贯通设置，也就是水平方向上贯通设置，波轮3转动推动的水可以顺畅的从进水口41进入到导流通道4中，从出水口42进入到循环水道200中，并且仍具有较强的向外甩出的离心力，能够顺着循环水道200的内壁向上爬升。本实施例的导流通道4可以在现有的洗衣机的无孔内桶1上直接进行改造，改动小，成本小，方式简单快捷。
本实施例中，循环水道200可以为单独的配件，该配件既可以本身具有空腔通道供水流通过，也可以与内桶1的外壁共同围合形成空腔通道，不论哪种方试，能够实现将导流通道4和喷水口201连通，形成循环水流即可。优选的，本实施例采用围合的方式形成循环水道200。具体的：
洗衣机包括水路盖板202，所述的水路盖板202固定设置在内桶1的外壁上，且与内桶1的外壁之间围合成空腔通道形成循环水道200；如此，可以利用内桶1的外壁作为循环水道200的一侧内壁，减少安装配件的厚度，减小重量、减少占用空间，有利于扩大洗衣机的有效洗涤空间。
本实施例的水路盖板202安装在内桶1的外壁上，既可以竖直设置，也可以倾斜设置，优选的所述的水路盖板202与内桶1的中心轴线平行设置，能够实现水流上爬，也便于加工和定位安装。
优选的，所述的水路盖板202包括与内桶1外壁相对且间隔设置的侧面板203以及位于侧面板203两侧、分别与内桶1外壁连接的连接板。
水路盖板202的侧面板203的长边与内桶1高度方向平行，并与内桶1的周向方向配合，连接板沿内桶1的径向或与径向方向成一定角度设置，侧面板203与两侧的连接板一体成型设置，如此形成一凹腔，水路盖板202安装在内桶1外壁上后，内桶1外壁与水路盖板202围合形成循环水道200。
进一步的方案，所述的侧面板203由下向上包括依次连接或一体成型的下连接段204、倾斜段205、竖直段206和上连接段207，下连接段204和上连接段207分别与内桶底2的外壁和上部外壁连接，竖直段206与内桶1外壁相对设置，倾斜段205与内桶底2的侧壁相对设置。
上连接段207和下连接段204起到连接固定作用，竖直段206形成循环水道200的主要 部分，倾斜段205与内桶底2的侧壁相对设置，也就是相对于内桶底2的导流通道4设置，有利于水流进入循环水道200时快速爬升，减少水流动能的损耗，增加喷射强度。
进一步的方案，所述的倾斜段205与导流通道4的出水口42相对设置，并由下向上朝远离内桶1中心的方向倾斜设置；有利于水流进入循环水道200时快速爬升，减少水流动能的损耗，增加喷射强度。
优选的，所述的水路盖板202的下连接段204与内桶1的连接处低于或平齐于导流通道4的出水口42的下边缘。如此，保证从导流通道4中排出的水流能够全部进入循环水道200中，循环喷射进入内桶1中。
进一步的方案，所述的导流通道沿内桶底11的周向间隔均匀设置多个，循环水道对应导流通道也设置多个，各导流通道的进水口均朝向波轮的中心轴线设置，出水口背向波轮的中心轴线设置。
一般的波轮3为盘形，转动时带动外周的水流均向外离心甩出。导流通道4沿着内桶底11的周向设置多个，导流通道4数量可以为奇数，沿着周向均匀间隔设置，也可以为偶数，以中心轴线为中心对称设置，进水口41均朝向波轮3的中心轴线设置，相应的出水口42背向波轮3的中心轴线，可以保证每个进水口41以最大的角度接收旋转的水流，同时降低对水流的阻碍作用，使水流进入对应的循环水道后仍然有足够的动能向上爬升。
优选的，水路盖板朝向内桶的内侧壁上设有由下向上延伸的导流筋，辅助从导流通道4排出的水向上爬升。
导流筋设置多个，每个导流通道4的出水口42均位于相邻的两个导流筋之间。导流筋可以由下向上竖直设置，也可以由下向上倾斜设置。导流筋倾斜设置时，可以为倾斜的直线型筋，也可以为弯曲的弧形筋，可以根据导流通道4中排出水的方向进行设置，同时导流筋还可以加强水路盖板的强度。
另外，本实施例的内桶的外部可以设置外桶，但内桶与外桶之间无水；也可以不设置外桶，而是设置集水装置来收集内桶排出的水。优选的方案，内桶外部不设置外桶，从而减少占用空间，扩大洗衣机的有效容积。
实施例二
如图1-4所示，本实施例为对实施例一的进一步的限定，本实施例的内桶底11包括相互连接的底壁111和侧壁112，侧壁112设置在底壁111外周边缘，底壁111和侧壁112共同 围合成内桶底11。所述的导流通道4设置在内桶底11的侧壁112上，或者设置在侧壁112与底壁111的连接处。
内桶底11的底壁111水平设置，侧壁112可以由底壁111外缘向上弯折形成。侧壁112上以及侧壁112与底壁111的连接处均可以设置横向贯通的导流通道4，能够将旋转的水流导流到内桶1和外桶2之间，但导流通道4的高度有所不同，对应的波轮3的位置也有所不同，相应的水流的旋转强度也有所不同。在波轮3旋转产生最大旋转水流对应的高度位置设置导流通道4将会大大提高水流的强度，可以增强喷射水流的力度和行程。
优选的，导流通道4设置在侧壁112与底壁111的连接处，导流通道4的进水口41的下边缘相对于上边缘向内凸出。
侧壁112与底壁111的连接处设置的导流通道4的位置稍低，与波轮3中部靠下的位置相对，旋转产生的水流强度大，离心力大，进入外桶2后可以快速向上爬升。同时，侧壁112与底壁111的连接处的承力强度大，开设导流通道4后对整个内桶底11的强度影响较小，在改造的同时可以保证内桶1的正常工作、安全性能。
进一步的方案，波轮3包括基体31，基体31的上表面设置有自基体31中心向基体31外周延伸的凸肋32，导流通道4的进水口41的高度不高于凸肋32的最高点的高度。
波轮3的基体31为盘形，优选圆盘形，基体31上表面的凸肋32向上凸起，并均匀间隔设置有多个，能够起到拨水的作用。凸肋32两侧为弧面，凸肋32向上凸起的同时，底部宽，且自下而上逐渐收窄，形成凸肋32的顶部。凸肋32为空心结构，凸肋32的下底开放。凸肋32自基体31的中心向基体31外周成由低到高的曲线形延伸。凸肋32的顶部自最高点经圆滑曲面向下延伸与基体31外周连接。因此，在波轮3上的凸肋32的底部到其顶部的最高点之间的区域，在波轮3较高速转动时，能够产生大的离心力，推动水流向此区域的外周甩出。导流通道4的进水口41的高度不高于凸肋32的最高点的高度，能够保证导流通道4位于水流大强度向外甩出的区域，保证水流经过导流通道4后能够快速沿着外桶2内壁向上爬升，同时，也能够避免洗涤的衣物随水流冲入导流通道4中，避免对衣物造成损害。
优选的，导流通道4的进水口41正对凸肋32的中部，进水口41的高度与凸肋32的中部的高度相等。凸肋32的中部的面积大，搅拌力度强，因此产生的旋转水流的动力足，强度大，更加有利于水流快速沿着外桶2内壁向上爬升，并保持较大的强度喷射进入内桶1中。
每个导流通道4的直径大小的设置需要内桶底11的承力强度、规格、材质等综合确定， 在保证内桶底11承力强度足够的前提下，设置多个导流通道4来实现水流进入循环水道，喷淋至内桶1中。而为了使水流在经过导流通道4进入循环水道之间后，能够尽可能的保留动能向上爬升，导流通道4内的设置需要配合水流的方向，使水流顺畅的排出，具体的方案可以有以下几种，但不限于此：
方案1，所述的导流通道4的进水口41与出水口42的高度相等，导流通道4由进水口41一侧向出水口42一侧直线水平延伸。本方案的导流通道4直线水平延伸，基本与内桶底11的底壁111平行，水流进入进水口41后，不受阻碍，可以直接顺畅的排出，对水流的阻碍作用小，利于水流保持动能向上爬升。
方案2，所述导流通道4的出水口42的高度高于进水口41，导流通道4的内壁的高度由进水口41侧向出水口42侧逐渐上升。本方案的导流通道4由内向外向上倾斜一定的角度，也就是说水流由进水口41进入经出水口42排出，会有一个向上的扬程，导流通道4起到向上倾斜导流的作用，有利于水流向上爬升。此倾斜角度需要根据波轮3的转速、水流的方向等因素具体确定。
优选的，导流通道4的内壁由进水口41一侧向出水口42一侧呈曲线向上延伸。导流通道4的内壁为曲线，能够更顺畅的导通水流，有利于水流向上爬升。
进一步的方案，以上两种方案中的导流通道4由进水口41一侧向出水口42一侧逐渐收窄，形成沿内桶底11的侧壁112周向延伸一定距离的狭长的出水口42。
进水口41与内桶底11的侧壁112平滑过渡，减小水阻力，利于水的顺畅流动。进水口41的形状优选的设置为四周边缘平滑过渡的方形口，进水口41在竖直方向上有一定范围的延伸，可以较大范围收集凸肋32不同高度位置拨动的水流，有利于大量水流进入通道中。而出水口42与进水口41的形状不同，出水口42沿内桶底11的侧壁112周向延伸一定距离，形成在周向上狭长的方形的出口，如此，出水口42可以分散水流，避免水流成束的击打到外桶2内壁上，部分水流可能会回落到外桶2底部，避免浪费、消耗水流的动能。此种设置可以使导流通道4中的水分散后均可沿着外桶2内壁向上爬升，喷射到内桶1中的水流更均匀分散。
优选的，进水口41的面积大于出水口42的面积。水流经过导流通道4后可以有部分增压的作用，利于水流向上爬升。
进一步的方案，导流通道4的出水口42的边缘向上倾斜延伸；出水口42朝向外桶2的 内壁，出水口42的边缘向上倾斜延伸，可以使排出的水有一段向上的扬程，顺着向上导流，遇到外桶2内壁继续向上爬升，有利于缩短水流的爬升距离，利于水流喷射进入内桶1中。出水口42的边缘可以全部或者部分向上倾斜延伸。
优选的，导流通道4的出水口42的至少上边缘成曲面向上延伸；此种方式加工简单，节省成本，同时能够达到较好的辅助水流向上爬升的作用。
实施例三
如图4所示，本实施例为对实施例一的进一步的限定，所述内桶1外侧还设置有用于收集内桶1中排出的水的集水装置208，所述集水装置208包括具有上开口的集水腔209，所述内桶1与集水腔209的上开口连通，所述的循环水道200的下端位于集水腔209中。
本实施例中洗衣机的内桶1为无孔内桶1，仅在内桶1上部设置用于甩出脱出的水的脱水孔，内桶1可以用于盛水。集水装置208可以为外桶，优选桶口高度低于洗衣机的内桶1桶口，更优选的，外桶的桶口的高度略高于内桶1的桶底。或者，洗衣机的集水装置208也可以为另行设置的改进的结构，可以进一步起到扩大洗衣机容积的作用。
通过设置集水装置208，一方面当水从内桶1排出时，通过集水装置208将收集内桶1中脱水时甩出的水，防止水的溢出，另一方面，可以将集水装置208整体设置在内桶1的桶底的下部。由于集水装置208整体位于内桶1以下，使集水装置208不占据内桶1和箱体之间的空间，对内桶1的扩容不具有限制作用，为内桶1的扩容提供充裕的空间。
所述的循环水道200的下端位于集水腔209中，一是与内桶底2的导流通道4的位置相配合，另一个还可以减少占用空间，也避免水从连接处流出外溢。
优选的，所述的循环水道200的下端的外侧壁与集水腔209的内侧壁之间间隔一定距离设置；从而避免内桶1转动或震动时的撞桶几率，提高集水腔209的使用寿命，确保洗衣机安全运行。
优选的，所述的集水腔209的侧壁和循环水道200的下端外侧壁均由下向上朝远离内桶1中心的方向倾斜设置，
所述集水装置208包括安装板210和设置在安装板210上的挡水筋211，所述安装板210与挡水筋211围合形成集水腔209，所述挡水筋211为环状，所述挡水筋211与安装板210围合形成环状的集水腔209。所述挡水筋211倾斜设置，且自上而下向集水腔209的中轴线方向逐渐收缩，也就是由下向上朝远离内桶1中心的方向倾斜设置，通过将挡水筋211设置 成倾斜状，能够最大限度的增加集水量，更便于使用。而循环水道200的下端外侧壁，也就是实施例一中所述的倾斜段205，既能够配合挡水筋211，避免撞击，又能够有利于循环水道200中水流向上爬，增加喷射强度。
实施例四
本实施例为实施例一或实施例二或实施例三的进一步的限定，提供一种波轮洗衣机的控制方法，波轮洗衣机包括内桶，在洗涤/漂洗时所述的内桶为盛水桶，内桶的外壁上设有循环水道，循环水道的两端分别与内桶的底部和上部连通；
波轮洗衣机执行洗涤程序时，至少执行一次涡流洗涤过程，所述的涡流洗涤过程为：波轮高速运转，推动内桶底部的水流进入循环水道并向上爬升，由喷水口喷射至内桶中，形成循环水流。
进一步的方案，洗涤程序包括普通洗涤过程和涡流洗涤过程，涡流洗涤过程的波轮的转速大于普通洗涤过程中波轮的转速；其中，普通洗涤过程为现有的洗衣机的洗涤过程，洗涤水在内桶中运动；
进一步的方案，洗涤程序中普通洗涤过程和涡流洗涤过程均为多个，普通洗涤过程和涡流洗涤过程交替执行。
通过普通洗涤过程和涡流洗涤过程交替执行，使涡流洗涤过程增高的温度能够迅速被普通洗涤过程吸收，使电机的温度不至于累积升高，减少电机过热保护停止和损坏的概率，提高洗衣机的使用寿命。
在执行涡流洗涤过程时，洗衣机控制波轮的转动方向不变，在执行普通洗涤过程时，洗衣机控制波轮的正转和反转交替进行。
最好是，在执行涡流洗涤过程时，洗衣机控制波轮正转，在执行普通洗涤过程时，洗衣机控制电机正转/反转交替进行。这种正反转交替的方式，更容易使吸收的热量分散，便于热量的散失，使散热效果更好。正转和反转交替执行的方式，使洗衣水流动性大，散热效果更好。
进一步地，普通洗涤过程持续时长为涡流洗涤过程持续时长的3-20倍。由于涡流洗涤过程能够提高衣物的洗净效果，但是，时间过长又会造成电机过热停止，通过控制二者时间的比例，使普通洗涤过程的运转时常既能够将涡流洗涤过程产生的热量分散吸收又能保证洗涤时间短，减少电机损坏的可能。
优选地，涡流洗涤过程的持续时长为5-300s。
进一步的方案，洗涤程序还包括间歇过程，所述间歇过程在相邻的普通洗涤过程和涡流洗涤过程之间执行，在执行间歇过程时，洗衣机控制波轮停止转动。通过设置间歇过程，使切换比较缓和，减少电机的损坏。为了保证在尽可能短的时间内将衣物洗净，间歇过程持续时间最好为2s。
具体来说，一种洗衣机的控制方法，包括以下步骤，
程序选择：用户选择洗涤程序，
涡流洗涤过程：洗衣机控制波轮高速转动，执行涡流洗涤过程，水流经由内桶底侧壁的导流通道，沿循环水道向上爬升后喷射进入内桶中进行衣物洗涤，涡流洗涤过程的持续时长为10-40s，
间歇过程：洗衣机控制波轮停止转动，间歇过程持续时间最好为2s；
普通洗涤过程：洗衣机控制内桶中的波轮正反转交替进行，内桶不转，搅动洗衣水进行衣物洗涤，普通洗涤过程持续时长为涡流洗涤过程持续时长的3-20倍；
循环交替：普通洗涤过程结束后再执行涡流洗涤过程，如此循环，直至洗涤程序结束。
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。
