Description

洗涤设备 技术领域
本发明属于洗涤领域，具体地说，涉及一种洗涤设备。
背景技术
现有的波轮洗衣机，内桶的周壁上设有多个脱水孔，内桶和外桶之间连通，内桶为衣物存放区，用于衣物的洗涤，内桶与外桶侧壁之间充满的这部分水不参与洗涤，真正参与洗涤的水是内桶中的部分，这使得水资源浪费巨大，另外，内桶和外桶之间过多的水也会降低洗涤剂的浓度，影响洗涤效果。与此同时，由于水流在内桶、外桶之间频繁进出，持续使用之后，内桶与外桶的侧壁之间的区域也成了藏污纳垢的空间，自来水里的水垢、洗衣粉的游离物、衣物的纤维素、人体的有机物及衣物带入的灰尘与细菌极易滞留在内桶与外桶的侧壁之间。这些霉菌是用久了的洗衣机内部积蓄的大量污垢、因不能有效去除而滋生繁殖的，这些使用者看不到的污垢如果不予清除，那么在下一次洗涤后，细菌又会附着在衣物上而带给人体，造成交叉感染的问题。
针对该情况，有些厂商做出了改进，为了节省水资源，洗衣机越来越多的采用无孔内桶的方式，使内外桶分离，只用内桶储水，而外桶无水。在内桶侧壁靠上端开设有排水孔或者采用自上向下的导水通道将水导出，这样，当洗衣机脱水时，水由于离心力的作用被甩在内桶内壁上，并沿内桶内壁向上移动，从内桶上端的排水孔直接排出或通过导水通道导出，这样提高了洗衣机节水的效果，并节约了洗涤剂的用量，更能够避免内外桶之间滋生细菌对衣物造成交叉污染。
上述结构相对于传统洗衣机虽然作出了改进，但是，还存在如下缺陷：排水只能依靠驱动内桶转动使得水从上部出水孔排出，排水时间长；另外，排水过程中，需要驱动装置工作，耗电相对高；最后，长时间使用，沉积性污物如泥沙颗粒等无法排出，积攒在内桶中，积攒过多则容易滋生细菌二次污染衣物，甚至于磨损衣物或内桶中的部件，如波轮轴密封部件等。
为了解决上述技术问题，申请人之前研发的技术，在内桶底设有排水口，并在该排水口设于可控开闭的排水机构，为了使得排水机构能够与排水口配合实现密封，还设置限定内桶位置的锁止机构，例如，申请号为CN201510057876.4的中国专利公开了一种洗衣机内桶的锁止机构及洗衣机，内桶底部设有一第一定位结构，外桶底部设有一第二定位结构，所述第二 定位结构为可伸缩结构，所述第一定位结构和所述第二定位结构凹凸配合，内桶被锁定，所述第一定位结构和所述第二定位结构脱离，内桶解除锁定。所述内桶底部设有一锁止孔，所述外桶底部至少设置一可伸缩的锁止杆，所述锁止杆伸入锁止孔，内桶被锁定，所述锁止杆脱出锁止孔，内桶解除锁定。洗涤时内桶被锁定，内外桶之间无水。
具体而言，在内桶底部设置锁止孔，并利用可伸缩的锁止杆与锁止孔相互配合，锁止杆伸出时与锁止孔凹凸配合，内桶锁定，锁止杆缩回时脱出锁止孔，内桶接触锁定。
其中，当内桶被锁定时，利用排水机构关闭内桶的排水口，而当内桶转动时，排水机构打开内桶的排水口，内桶内的水由排水口先流入外桶，然后再从外桶排出，但在此该结构中，锁止机构和排水机构分别驱动，且先驱动锁止杆伸出与锁止孔凹凸配合锁定内桶后，然后在控制排水机构密封内桶的排水口。该结构复杂，必须采用两套驱动机构分别驱动锁止机构和排水机构，生产成本高；另外，控制复杂，对控制精确性要求较高。
有鉴于此特提出本发明。

本发明洗涤设备中对于洗涤桶的锁止单元和排水单元采用一体驱动，采用本发明的结构实现了洗涤桶先锁止、后密封，避免了锁止单元与排水单元同时作用时洗涤桶的转动对排水单元造成的磨损。
1.锁止单元和排水单元一体驱动，结构简单，节约了生产成本，安装方便，一体化的模块结构利于安装，精简了两个部件独自安装的流程；
2.锁止单元与洗涤桶锁止位置的最小距离小于排水单元与排水口的最小距离，使得驱动单元同步输出动力，在锁止单元先一步锁定洗涤桶时，排水单元与洗涤桶底部的排水口还有一定的安全距离，避免排水单元与锁止单元同时阻挡洗涤桶转动造成排水单元磨损或变形；
3.锁止单元和排水单元采用同步驱动，锁止、封堵动作间隔完成的控制结构，控制更简洁、顺畅，降低了故障率。
下面结合附图对本发明的具体实施方式作进一步详细的描述。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，以下实施例用于说明本发明，但不用来限制本发明的范围。
在本发明的描述中，需要说明的是，术语“上”、“下”、“前”、“后”、“左”、 “右”、“竖直”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是直接相连，也可以通过中间媒介间接相连。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
如图1至图7所示，本发明所述的洗涤设备，包括外壳(图中未示出)，可转动的设置在外壳内的洗涤桶1，支撑洗涤桶1的接水槽2。洗涤桶1底部设有排水口3，进水、洗涤过程排水口3封闭，洗涤桶1为盛水桶。洗涤设备还包括排水单元4、锁止单元5和驱动单元6，排水单元4安装于洗涤桶1下方接水槽2底，可活动地靠近/远离洗涤桶1以控制排水口3的开闭；锁止单元5设于洗涤桶1下方接水槽2底、排水单元4的一侧，可活动地靠近/远离洗涤桶1以阻挡/释放洗涤桶1的转动。
本发明排水单元4和锁止单元5共用一驱动单元6，通过传动件7同步驱动排水单元4和锁止单元5靠近/远离洗涤桶1，在锁止单元5远离洗涤桶1的位置，锁止单元5与洗涤桶1锁止位置的最小距离小于排水单元4与排水口3的最小距离。该结构使得驱动单元6同步输出动力，锁止单元5先进入有效工作距离范围时，排水单元4与洗涤桶1底部的排水口3还有一定的安全距离，避免排水单元与锁止单元同时阻挡洗涤桶转动造成排水单元磨损或变形。
所述的接水槽通过减振单元与洗涤设备的外壳连接(图中未示出)，接水槽支撑洗涤桶，不仅使得洗涤桶可转动的设置在外壳内，也能够收集洗涤桶排出的洗涤水，由与接水槽连通的排水单元排出至洗涤设备外部。该减振单元可采用现有波轮洗衣机的吊杆减振结构，也可采用安装在接水槽下方向上支撑的阻尼减振结构，或者采用上述的组合。
该接水槽2为桶状结构、盘状结构，或者由支撑在洗涤桶下方的支撑板和设置在支撑板上方的环形凸筋构成；还可以采用现有洗衣机的外桶或低于洗涤桶上端沿的凹槽结构(参阅图1和图7)。如图1所示，排水单元4和锁止单元5设于接水槽2底部，上端均可活动地穿过接水槽2底部，且与接水槽2底部密封设置，下端活动穿设于固定座11内，固定座11固定安装在接水槽2底。
本发明的洗涤设备在进水洗涤时，洗涤桶底部的排水口被封闭，洗涤桶为盛水桶，洗涤 时，可控制洗涤桶内的波轮独自转动，也可控制波轮和洗涤桶分别转动；排水时，洗涤桶底部的排水口打开，洗涤桶内的水排出至外部的接水槽内，然后由排水管排出；脱水时，驱动洗涤桶高速转动，衣物中的水分受离心力甩出沿洗涤桶周壁向上爬升，由洗涤桶周壁上部的脱水孔甩出，或者由洗涤桶1周壁上的导水通道14自上向下引导至外部的接水槽2内(参阅图7)。
作为本发明的一种实施方案，如图1、图3至图5所示，本发明所述的排水单元4包括阀塞41和带动阀塞41运动的阀塞杆42；所述的锁止单元5包括锁止杆51，洗涤桶1底部设有与锁止杆51上端部配合的锁止凹部12；
在锁止杆51上端部远离洗涤桶1的锁止凹部12位置，阀塞41的上端面与排水口3配合密封处的最小距离大于锁止杆51上端部与锁止凹部12有效锁止的最小距离。
进一步的，所述锁止杆51上端部高于阀塞41上端面所在的水平面，高度差为H(参阅图3至图5)。
和/或，所述锁止凹部12有效限制锁止杆51的位置低于排水口3密封处所在的水平面。
本发明洗涤设备通过阀塞41密封排水口3，该结构在进水及洗涤过程，锁止单元5和排水单元4同步靠近洗涤桶底，洗涤桶1被锁止不能转动，同时排水口3被密封；在排脱水过程，锁止单元5和排水单元4同步远离洗涤桶底，洗涤桶1为自由状态，同时排水口3被打开。
作为本发明的进一步实施方案，如图6和图7所示，本发明所述的洗涤桶排水口3设有可开闭的密封结构13，密封结构13常闭排水口3；所述的排水单元4包括顶杆43，顶杆配置为可控制向上移动开启密封结构13。
在锁止杆51上端部远离洗涤桶1的锁止凹部12位置，顶杆43上端与密封结构13的最小距离大于锁止杆51上端部与锁止凹部12有效锁止的最小距离。
进一步的，所述锁止杆51上端部高于顶杆43上端部。
和/或，所述锁止凹部12有效限制锁止杆51的位置低于密封结构13被顶杆43抵触位置所在的水平面。
本发明洗涤设备通过密封结构13常闭排水口3，仅仅在排水过程中，利用顶杆43上升开启密封结构13执行排水，因此，本发明洗涤桶1在进水及洗涤过程，排水口3是被密封结构13封闭的，该过程能够驱动洗涤桶转动，获得更多的洗涤水流。
进一步的实施方案为，本发明所述的洗涤桶1底部的锁止凹部12为锁止孔，或者为设于洗涤桶1底部的阻挡部构成用于阻挡锁止杆的限位凹部。优选的，所述的锁止孔设于洗涤桶底法兰盘8上(参阅图3)。
作为本发明的一种实施方案，如图1所示，本发明所述的排水单元4和锁止单元5集成为一体结构，可活动地设于同一固定座11上。
进一步优选的，排水单元4和锁止单元5可上下伸缩设置在固定座11上。
作为本发明的一种实施方案，本发明所述的驱动单元6为驱动电机，传动件7配置为将驱动电机输出的旋转转换为排水单元4/锁止单元5往复直线运动的传动结构。优选的，驱动单元6固定安装在固定座11上，与排水单元4、锁止单元5、固定座11集成为一体结构。
还优选的，如图2所示，传动件7包括传动轮9和传动杆10，传动轮9安装在驱动电机轴上，传动杆10一端与传动轮9偏心活动连接，另一端与排水单元4/锁止单元5活动连接。
或者，传动件7为螺旋传动部件。
作为本发明的一种替换方案为，所述的阀塞杆为一中空的排水管结构，阀塞为套设在阀塞杆上端部与排水口周边的密封圈结构，阀塞杆的下端通过一软管与排水阀连接(图中未示出)。该结构在进水及洗涤过程，锁止单元和排水单元同步靠近洗涤桶底，洗涤桶被锁止不能转动，同时排水口3被密封，该状态阀塞杆下端连通的排水阀为闭合状态阻止洗涤桶内的水流出；在排水过程，有两种控制方式，一种为，锁止单元5和排水单元4同步远离洗涤桶底，洗涤桶1为自由状态，同时排水口3被打开，洗涤桶内的水流入接水槽2内，通过接水槽2另外设置的排水结构排出，或者阀塞杆向下移动满足阀塞杆上端不高于接水槽底内表面，由该中空的阀塞杆排出接水槽内的水；另一种为，锁止单元和排水单元保持进水和洗涤过程中的状态不变，打开阀塞杆下端连通的排水阀，由该排水阀排水。在脱水过程，锁止单元5和排水单元4同步远离洗涤桶底，洗涤桶1为自由状态，同时排水口3被打开，洗涤桶内的水流入接水槽2内，通过接水槽2另外设置的排水结构排出，或者阀塞杆向下移动满足阀塞杆上端不高于接水槽底内表面，由该中空的阀塞杆排出接水槽内的水。
作为本发明的一种实施方案，如图1和图7所示，本发明所述的洗涤桶1上部设有平衡环15，为了使得受离心力向上爬升的水不从洗涤桶1和平衡环15连接处甩出去导致溅水，平衡环15与洗涤桶1上端密封连接。可采用平衡环15外侧壁与洗涤桶1上端的内周壁之间密封，或者采用平衡环15支撑在洗涤桶1上端沿，两者之间设置为端面密封，或者两组组合，再或者，通过滚压包边的方式，夹设密封圈的方式等实现两者密封。
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。
