Description

一种内外桶间无水的洗衣机 技术领域
本发明涉及洗衣设备技术领域，具体地，涉及一种内外桶间无水的洗衣机。
背景技术
现有的洗衣机包括壳体以及设置在壳体内的外桶、内桶，内桶可转动的设置在外桶内。为了实现衣物的脱水功能，内桶的桶壁上布满了脱水孔，这样在进行衣物洗涤时，洗涤水会由脱水孔流至内桶与外桶之间，这部分洗涤水不能得到充分的利用而导致水资源的浪费。
另外，由于内桶与外桶之间存水的问题，会导致在内桶的外壁、外桶的内壁以及内桶与外桶之间的区域滋生污垢，污染用户衣物，严重影响用户的洗衣体验。
为了解决上述问题，现有一种洗衣机，其主要的结构特点是内桶的桶壁上无孔，这样，在洗涤时，只在内桶中有水，内桶与外桶之间无水，不仅节省了洗衣的用水量，而且杜绝了内桶与外桶之间滋生污垢，避免衣物污染，提高洗涤效果，提升用户体验。
上述在洗涤时内桶与外桶间无水的洗衣机在使用一段时间以后，由于内桶上无孔，洗涤后的泥沙等杂物可能无法及时排出，影响用户洗衣效果。
为了解决洗涤时内桶与外桶间无水的洗衣机的泥沙等杂物的排出问题，特提出本发明。
发明内容
为了解决上述问题，本发明提供一种内外桶间无水的洗衣机，具体地，采用如下的技术方案：

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，所述内桶的底部上设置排水密封装置和驱动装置，排水密封装置包括与排水孔配合以控制其开启/关闭的密封部和与驱动装置连接的连接部；
在洗涤/漂洗时，所述排水密封装置的密封部保持排水孔封闭，在排水/脱水时，所述的排水密封装置在驱动装置的作用下将排水孔打开。
进一步地，所述的密封部为封水盖，所述的连接部为杠杆结构：杠杆结构的阻力臂端 连接封水盖，动力臂端连接驱动装置；
所述的杠杆结构在驱动装置的作用下带动封水盖在洗涤和漂洗过程中关闭排水孔排水孔，在排水/脱水时打开排水孔排水孔。
进一步地，所述的杠杆结构包括杠杆和杠杆支架，杠杆支架固定在内桶的底壁外侧，杠杆可转动的安装在杠杆支架上；
所述的驱动装置为电机，电机的输出端作用于杠杆的动力臂端带动其上下运动，以带动封水盖在洗涤和漂洗过程中关闭排水孔排水孔，在排水/脱水时打开排水孔排水孔。
进一步地，所述杠杆的动力臂与阻力臂之间呈一夹角设置，所述的电机为拉伸电机，拉伸电机的输出轴连接杠杆的阻力臂；
优选地，所述的杠杆的动力臂与阻力臂之间的夹角大于等于90°。
进一步地，所述杠杆上安装弹性装置，弹性装置作用于杠杆的阻力臂端用于带动封水盖复位关闭排水孔。
进一步地，所述的驱动装置采用无线充电模块进行供电；或者，所述的驱动装置包括独立设置的电池模块进行供电。
进一步地，所述的无线充电模块包括送电线圈和受电线圈：
所述的受电线圈安装在内桶的底部外壁上且与驱动装置电连接；
所述的送电线圈安装在外桶外壁上或者洗衣机壳体内，送电线圈连接电源。
进一步地，所述的送电线圈安装在外桶的底部外侧，且与受电线圈对应。
进一步地，所述的驱动装置密封安装在内桶的底部外壁上。
进一步地，还包括密封罩，密封罩密封安装在内桶的底部外壁上；所述排水密封装置和驱动装置均设置在密封罩内。
本发明的内外桶间无水的洗衣机，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，即本发明的洗衣机的内桶为桶壁上无孔的不漏水内桶，内部盛水用于洗涤衣物。本发明内桶的底部开设排水孔，用于洗涤结束后排水。
本发明将排水密封装置和驱动装置均安装在内桶上，脱水时随同整个内桶的旋转而旋转，这样，就不需要在洗涤过程中另外附加锁止机构将内桶锁止，从而解决此问题。
本发明的内外桶间无水的洗衣机实现了桶壁上无孔的不漏水内桶的排水，同时比较好的解决了泥沙等杂物积聚的问题，结构简单，易于实现。
本发明的驱动装置安装在转动的洗衣机内桶上，无法通过正常的导线供电，本发明采用无线充电的方式实现其供电：
洗涤过程中，送电线圈不通电，根据电磁感应原理，受电线圈不会有电流产生，对驱动装置不能供电。封水盖安装于杠杆上，在安装于支架上的弹性装置的作用下，将内桶底部的排水孔封堵，实现洗涤过程不漏水。
排水时，送电线圈通电，根据电磁感应原理，受电线圈会产生感应电流，对驱动装置供电，驱动装置动作并拉动杠杆，根据杠杆原理，封水盖将开启内桶底部上的排水孔，实现排水。
脱水时，送电线圈保持通电，根据电磁感应原理，受电线圈会产生感应电流，对驱动装置持续供电，驱动装置动作并拉动杠杆，根据杠杆原理，封水盖将保持开启内桶底部上的排水孔，部分甩出的水以及洗涤过程中产生的泥沙等杂物可由排水孔排出。脱水运转时，排水密封装置、驱动装置以及受电线圈均跟随内桶一起旋转，避免了将驱动装置设置在外桶上，将驱动装置设置在外桶上造成的定位问题。

具体实施方式
下面结合附图对本发明的一种内外桶间无水的洗衣机进行详细描述：
如图1及图2所示，本实施例的一种内外桶间无水的洗衣机，包括：
外桶11；
内桶10，可转动的设置在外桶11内；
在洗涤/漂洗过程中，所述的内桶10内盛水，内桶10与外桶11之间无水；
所述内桶10的底部开设排水孔13，所述内桶10的底部设置排水密封装置和驱动装置，排水密封装置包括与排水孔配合以控制其开启/关闭的密封部和与驱动装置连接的连接部；
在洗涤/漂洗时，所述排水密封装置的密封部保持排水孔封闭，在脱水时，所述的排水 密封装置在驱动装置的作用下将排水孔打开。
本实施例的排水密封装置在洗涤/漂洗过程中将排水孔13封堵，避免洗涤水进入到内桶10与外桶11之间的区域，保持桶间无水，避免滋生污垢，污染用户衣物。排水密封装置在脱水过程中，开启排水孔13，不仅可以实现脱水排水，还可以将洗涤过程中的泥沙等杂物排出，保持内桶内的清洁。
本实施例的驱动装置为带动排水密封装置开启/关闭排水孔13的动力源。
本实施例的内桶10包括内桶底9，所述的排水孔13设置在内桶底9上。
本实施例的内外桶间无水的洗衣机，在洗涤/漂洗过程中，所述的内桶10内盛水，内桶10与外桶11之间无水，即本发明的洗衣机的内桶10为桶壁上无孔的不漏水内桶，内部盛水用于洗涤衣物。本发明内桶10的底部开设排水孔13，用于洗涤结束后排水。
本实施例将排水密封装置和驱动装置均安装在内桶上，脱水时随同整个内桶的旋转而旋转，这样，就不需要在洗涤过程中另外附加锁止机构将内桶锁止，从实现了桶壁上无孔的不漏水内桶的排水，同时比较好的解决了泥沙等杂物积聚的问题，结构简单，易于实现。
另外，作为本实施例的一种优选实施方式，本实施例的内桶10的只在侧壁的上部设置一周脱水排水孔，脱水排水孔设置在洗衣机内桶最大进水量以上的位置，在脱水时用于将脱出的水从此排出，而内桶10侧壁的其它部位则是封闭设计的，不设置任何通孔结构。同时，内桶10的底壁上除了设置一个孔径较大的排水孔13外，所述的排水孔13在洗涤和漂洗过程中关闭，在排水时打开排水孔，而内桶底壁的其它部位则是封闭设计的。
作为本实施例的一种优选实施方式，排水密封装置和驱动装置均安装在内桶的底部外壁上。
作为本实施例的一种实施方式，本实施例的密封部为封水盖3，所述的连接部为杠杆结构：杠杆结构的阻力臂端连接封水盖3，动力臂端连接驱动装置；所述的杠杆结构在驱动装置的作用下带动封水盖在洗涤和漂洗过程中关闭排水孔，在排水时打开排水孔排水孔。本实施例的排水密封装置采用杠杆结构，排水孔的打开或者关闭均受到杠杆的作用，更加可靠。
进一步地，本实施例所述的杠杆结构包括杠杆4和杠杆支架6，杠杆支架6固定在内桶10的底壁外侧，杠杆4可转动的安装在杠杆支架6上。本实施例为了实现杠杆结构进行杠杆运动，所述的驱动装置的输出端应作用于杠杆的动力臂端，具体地：
实施方式一：本实施方式的驱动装置包括凸轮和电机，所述的凸轮安装在电机的输出轴上，凸轮在电机的带动下转动。凸轮安装在内桶10的底壁外侧，凸轮的轮廓曲面与杠杆 4的动力臂端相接触，所述的轮廓曲面随着凸轮转动下压/松开杠杆4的动力臂实现杠杆结构的杠杆运动。
本实施例通过凸轮在转动过程中，通过轮廓曲面的不同曲面与杠杆4的动力臂端接触，当曲率半径大的面与杠杆4的动力臂端接触，凸轮下压杠杆4的动力臂，杠杆4的动力臂端受压向上运动，杠杆4的阻力臂端向下运动带动封水盖3打开排水孔13；当曲率半径小的面与杠杆4的动力臂端接触，凸轮松开杠杆4的动力臂，杠杆4的动力臂端向下回位，杠杆4的阻力臂端向上运动带动封水盖3关闭排水孔。
本发明的轮廓曲面包括至少包括第一曲面、第二曲面和第三曲面，第一曲面的的曲率半径逐渐增大，第二曲面的曲率半径等于第一曲面的曲率半径的最大值，第三曲面的曲率半径略小于第二曲面的曲率半径。因此，本发明的封水盖3关闭时，轮廓曲面的第一曲面与杠杆4的动力臂端接触，轮廓曲面随着凸轮的转动过程中，第一曲面、第二曲面分别与杠杆4的动力臂端接触，当达到曲率半径最大的第二曲面后继续转动至第三曲面后停止，第三曲面下压杠杆4的动力臂端，封水盖3打开，这样主要是当凸轮停止转动后，第三曲面的曲率半径略小于第二曲面的曲率半径可防止凸轮回转，确保封水盖3打开状态更加的可靠。
实施方式二：本实施方式的驱动装置为电机7，电机7的输出端作用于杠杆的动力臂端带动其上下运动，以带动封水盖3在洗涤和漂洗过程中关闭排水孔排水孔，在排水时打开排水孔。
进一步地，所述杠杆4的动力臂与阻力臂之间呈一夹角设置，所述的电机7为推拉电机，推拉电机的输出轴连接杠杆的阻力臂。本实施例通过推拉电机伸缩运动即可拉动杠杆4的动力臂上下运动，进而实现杠杆结构的杠杆运动，以关闭/开启排水孔13。
优选地，所述杠杆的动力臂与阻力臂之间的夹角大于等于90°。杠杆的动力臂与阻力臂之间呈钝角的设置可以保证推拉电机输出的动力更多的分解成竖直方向上的力以实现杠杆运动。
作为本实施例的一种优选实施方式，所述杠杆上安装弹性装置，弹性装置作用于杠杆4的阻力臂端用于带动封水盖复位关闭排水孔13。
具体地，杠杆结构的杠杆4和杠杆支架6之间设置用于杠杆4复位的弹簧5。本实施例通过弹簧5即可实现杠杆4的复位，并保持排水孔13的密封，结构简单，安装方便，且可靠有效。
作为本实施例的一种优选实施方式，所述封水盖3与杠杆结构的阻力臂端通过铰链连 接，封水盖3可绕杠杆结构的阻力臂端的中心线自由转动，封水盖3与内桶底壁之间具有0～15°活动夹角，优选地，所述的活动夹角为5°。由于杠杆结构的运动轨迹是直线，所以当封水盖3盖在排水孔上时，有可能会一部分先接触而另一部分还未接触，会导致排水孔盖的不严而漏水，将排水盖3采用铰接的方式连接在杠杆结构上，这样可使得封水盖3具有一定的活动角度，更加便于封水盖3盖住排水孔。
作为本实施例的一种优选实施方式，所述的内桶10的排水孔外围设置挡水筋17，挡水筋17的作用主要是防止排水孔13排水时水流对杠杆结构进行冲刷造成杠杆结构不稳定，甚至造成损坏。进一步地，挡水筋17上对应杠杆4处设置豁口18，这样可防止挡水筋17妨碍杠杆4正常上升、下降，使得封水盖3的关闭、开启更加顺利。由于挡水筋17只是为了减少流向杠杆结构处的水流，优选地，所述的挡水筋17设置在排水孔13靠近杠杆结构的一侧。
本发明的驱动装置安装在转动的洗衣机内桶上，无法通过正常的导线供电，本发明采用无线充电的方式实现其供电。
无线充电原理：
众所周知，电流流过线圈时，周围会产生磁场，其他未通电的线圈接近该磁场，线圈中就会产生电流，由此可以向驱动装置供电。
因此，将可以与磁场振动共振的线圈排列起来，就可以在实现无线供电的基础上，延长供电距离。
如图2、图3及图4所示，一种内外桶间无水的洗衣机，所述的驱动装置采用无线充电模块进行供电。
具体地，所述的无线充电模块包括送电线圈12和受电线圈8：所述的受电线圈8安装在内桶10的底部外壁上且与驱动装置电连接；所述的送电线圈12安装在外桶外壁上或者洗衣机壳体内，送电线圈连接电源15。
优选地，所述的送电线圈12安装在外桶的底部外侧，且与受电线圈8对应。这样，可以提高无线充电的传输功率。
进一步地，本实施例的送电线圈12与电源之间串联接入送电线圈电容14，受电线圈8与驱动装置之间串联接入受电线圈电容16，以增强整个无线充电系统的适应性和稳定性。
洗涤过程中，送电线圈12不通电，根据电磁感应原理，受电线圈8不会有电流产生，对驱动装置不能供电。封水盖3安装于杠杆4上，在安装于杠杆支架6上的弹性装置的作用下，将内桶10底部的排水孔13封堵，实现洗涤过程不漏水。
排水时，送电线圈12通电，根据电磁感应原理，受电线圈8会产生感应电流，对驱动装置供电，驱动装置动作并拉动杠杆4，根据杠杆原理，封水盖3将开启内桶10底部上的排水孔13，实现排水。
脱水时，送电线圈12保持通电，根据电磁感应原理，受电线圈8会产生感应电流，对驱动装置持续供电，驱动装置动作并拉动杠杆4，根据杠杆原理，封水盖3将保持开启内桶10底部上的排水孔13，部分甩出的水以及洗涤过程中产生的泥沙等杂物可由排水孔13排出。脱水运转时，排水密封装置、驱动装置以及受电线圈均跟随内桶一起旋转，避免了将驱动装置设置在外桶上，将驱动装置设置在外桶上造成的定位问题。
作为本实施例的一种实施方式，所述的驱动装置包括独立设置的电池模块进行供电。本实施例的电池模块密封安装，且可拆卸取出进行充电，或者直接接线充电。
作为本实施例的一种实施方式，所述的驱动装置密封安装在内桶的底部外壁上。
具体地，本实施例的洗衣机还包括密封罩，密封罩密封安装在内桶的底部外壁上；所述排水密封装置和驱动装置均设置在密封罩内。
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。
