Description

一种洗衣机排水结构 技术领域
本发明涉及洗衣机技术领域，具体地，涉及一种洗衣机排水结构。
背景技术
随着生活水平的提高，人们对洗衣机的要求越来越高，简单的洗衣已经达不到顾客的要求，尤其是能源与发展已经成为社会发展的主题，洗衣机在满足人们基本的洗衣要求的同时，节能也成为了衡量洗衣机的一个重要因素。普通的波轮洗衣机在注水的时候，内桶与外桶之间也有大量的水，洗涤的时候内桶外的水就浪费了。现有一种节水型洗衣机，这种洗衣机的内桶的桶壁下部不设置脱水排水孔，在注水的时候，只有内桶中有水，而内桶和外桶之间不存水，这样可以充分的利用洗衣机内的水，注水的时候比其它洗衣机少使用40％的水量，同时，也可以节省洗涤剂，另外，由于内桶内的注水量减少，在一定程度上减小了洗衣机的负载，也更加的省电。
然而，上述节水型洗衣机也具有一个缺点就是，由于内桶上不设置脱水排水孔，脱水时水不能及时排出，脱水启动困难，脱水启动振动较大，脱水时间较长，因此能效较低，脱水后的衣物含水率较高。
因此，如何更好的解决这种洗衣机的排水问题，对于提升用户的使用感受至关重要。

具体实施方式
下面结合附图对本发明的一种洗衣机排水结构进行详细描述：
如图1及图2所示，一种洗衣机排水结构，用于洗涤、漂洗时内外桶之间无水的洗衣机，洗衣机包括桶侧壁下部无孔的内桶1，所述的排水结构包括球阀33和驱动装置，所述内桶1的底壁设置排水口，球阀33的进水端口连通排水口，所述的球阀33在驱动装置的驱动下在洗涤和漂洗过程中关闭，在排水时打开。
本发明的内桶1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1的底壁上除了设置一个孔径较大的排水口外，所述的排水口在洗涤和漂洗过程中关闭，在排水时打开排水口，而内桶底壁的其它部位则是封闭设计的。
球阀是用带有圆形通道的球体作启闭件，球体随阀杆转动实现启闭动作的阀门。球阀 的启闭件是一个有孔的球体，绕垂直于通道的轴线旋转，从而达到启闭通道的目的。球阀主要供开启和关闭管道和设备介质之用。因此，本发明的洗衣机排水结构根据球阀的工作原理，排水口上安装的球阀33，通过驱动装置驱动球阀33的阀杆实现开启关闭。
本发明的洗衣机排水结构采用球阀主要具有以下优点：
1、可频繁进行开启、关闭操作，启闭迅速、轻便。
2、排水时流体阻力小。
3、结构简单，相对体积小，重量轻，便于维修。
4、密封性能好。
5、不受安装方向的限制，介质的流向可任意。
6、无振动，噪声小。
本发明的排水结构适用于洗涤、漂洗时内外桶之间无水的洗衣机，内桶1的底壁上设置排水口，排水结构的球阀33在驱动装置的驱动下在洗涤和漂洗过程中关闭，在排水时打开。因此，本发明的排水结构利用球阀的开关方式在驱动装置的驱动下关闭、打开排水口，实现排水，而且结构简单，安装方便，具有良好的市场推广价值。
作为本发明的一种优选实施方式，所述的球阀33包括第一阀杆30和第二阀杆31，所述的驱动装置驱动第一阀杆30转动90°开启球阀33，驱动装置驱动第二阀杆31回转90°关闭球阀33。
本发明的球阀33包括两个分别控制其开启和关闭的阀杆，这样，只需要控制驱动装置分别控制第一阀杆30和第二阀杆31转动，从而实现球阀33的开启与关闭。
具体地，所述的球阀33包括阀壳和球体，球体可转动的设置在阀壳内部，所述的第一阀杆30和第二阀杆31通过铰链32与球阀33的球体相连。
如何实现本发明的第一阀杆30和第二阀杆31的转动，进而开启、关闭球阀33是本发明的关键点。因此，本发明采用了如下的技术方案来驱动第一阀杆30和第二阀杆31的转动：
如图1、图3、图4及图5所示，所述的洗衣机包括同轴安装在外桶13内部的内桶1。
本发明所述的驱动装置包括安装在外桶13的底壁上的第一挡杆组件16和第二挡杆组件17。
所述的内桶1正向转动时，第一挡杆组件16阻挡第一阀杆30反向转动90°后开启球阀33，内桶1反向转动时，第二挡杆组件17阻挡第二阀杆31正向转动90°后关闭球阀33。
本发明所述的正向转动或者反向转动并不限定内桶1朝着某一固定的方向转动，只是限定了内桶1在排水时需要进行双向的旋转，例如当顺时针转动为正方向时，则逆时针转 动为反方向转动，反之亦然，本发明的附图中以内桶1顺时针转动为正方向，内桶1逆时针转动为反方向。本发明的内桶1进行双向转动，以实现在排水前打开球阀33，在排水完成后关闭球阀33。
作为本发明的一种优选实施方式，所述的第一挡杆组件16和第二挡杆组件17分别包括可上下运动的挡杆23。所述的第一挡杆组件16和第二挡杆组件17的挡杆23需要分别单独作用于第一阀杆30和第二阀杆31，如果作用对象错误，则不能实现球阀33的开启、关闭。
因此，所述的第一挡杆组件16设置在第二挡杆组件17的外侧，第一阀杆30的长度大于第二阀杆31的长度，使得第一挡杆组件16的挡杆23向上运动时只阻挡第一阀杆30。
这样将第一挡杆组件16设置在第二阀杆31的自由端外侧，第一挡杆组件16向上运动时不可能阻挡到第二阀杆31，而只能阻挡第一阀杆30，第一阀杆30在其阻挡下带球阀33的球体通道连通，球阀33开启。
所述的第二挡杆组件17的挡杆23的长度小于第一挡杆组件16的挡杆23的长度，第二阀杆31与外桶13的底壁之间的距离小于第一阀杆30与外桶13的底壁之间的距离，使得第二挡杆组件17的挡杆23向上运动时只阻挡第二阀杆31。
这样，第二挡杆组件17的挡杆23向上运动的高度只能阻挡到第二阀杆31而阻挡不到第一阀杆30，第二阀杆31在其阻挡下带球阀33的球体通道截止，球阀33关闭。
本发明所述的第一阀杆30和第二阀杆31的长度满足：第一阀杆30在第一挡杆组件16阻挡下反向转动90°后与其分离，第二阀杆31在第二挡杆组件17阻挡下正向转动90°后与其分离。
这样主要是第一阀杆30和第二阀杆31转动到位以后，球阀33才能开启和关闭，而且，当球阀33完成开启和关闭以后，第一阀杆30和第二阀杆31转动到位以后便不能再转动，第一挡杆组件16和第二挡杆组件17必须与之分离才能不影响到内桶1的运行。
因此，第一阀杆30和第二阀杆31的自由端均不得超出内桶1的边缘设置。
如图6及图7所示，本发明所述的第一挡杆组件16和第二挡杆组件17均包括挡杆23、螺母24、密封套25、固定盘26和压缩弹簧27，所述的挡杆23穿过外桶13的底壁，本发明的第一挡杆组件16和第二挡杆组件17的挡杆23可上下运动，以阻挡第一阀杆30和第二阀杆31。挡杆23的上部位于内桶1与外桶13之间，下部位于外桶13的底壁外部，所述的密封套25套在挡杆23的上部且能够随着挡杆23的运动伸缩，密封套25一端通过螺母24固定在挡杆23上，另一端通过固定盘26固定在外桶13的底壁上并与其密封，以确保第 一挡杆组件16和第二挡杆组件17与外桶13之间密封，防止漏水。
本发明所述的压缩弹簧27设置在挡杆23的下部，所述的挡杆23的下端端部设置用于阻挡压缩弹簧27的一端的阻挡螺母29，所述的压缩弹簧27设置在外桶13的底壁与阻挡螺母29之间。
进一步地，所述的外桶13上安装有固定座28，所述的挡杆23穿过固定座28，压缩弹簧27设置在固定座28与阻挡螺母29之间，这样可防止压缩弹簧27受压时施力于外桶13上，造成外桶13频繁受压造成损坏。
由于本发明的球阀33安装在内桶1和外桶13之间，因此为了提供其足够的安装空间，所述的外桶13的底壁设置凹槽结构15，所述的第一挡杆组件16和第二挡杆组件17安装在凹槽结构15上，所述的凹槽结构15上设置外桶排水口14。
为了实现本发明的第一挡杆组件16和第二挡杆组件17的挡杆23上下运动，作为本发明的一种优选实施方式，如图3、图4及图5所示，所述的驱动装置还包括压板20、支架21、拉杆22和牵引电机19，支架21固定在外桶13的底壁外侧，拉杆22可转动的安装在支架21上，拉杆22的一端连接牵引电机19，另一端与压板20固定连接，压板20的两端分别压在第一挡杆组件16和第二挡杆组件17上；
所述的拉杆22和压板20在牵引电机19的牵引下绕着支架21转动，压板20的一端上升，压动第一挡杆组件16向上运动，压板20的另一端下降，第二挡杆组件17向下运动。
作为本发明的一种优选实施方式，所述的牵引电机19通过拉绳18与拉杆22相连接。
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。
