Description

一种衣物处理装置排水控制方法及多筒衣物处理装置 技术领域
本发明属于洗衣机设备领域，具体地说，涉及一种衣物处理装置排水控制方法及多筒衣物处理装置。
背景技术
目前，市场上在售的滚筒洗衣机多数只有一个洗涤筒。随着人们的卫生意识的加强，越来越多的用户需要将不同类型的衣物分开洗涤或少量衣物及时洗涤。随着人们生活质量的提高，卫生意识也逐渐提高，尤其在家庭衣物洗涤方面，越来越多的人将衣物分开洗涤。如果用现有洗衣机采取多次洗衣的方式，在洗涤时间上难以满足要求；如果购买两台或多台洗衣机分开同时洗涤，不仅会带来能源和水资源的极大浪费，而且占据空间大，不适于家庭使用。因此，用多筒洗衣机即可满足上述需要，解决能源和水以及空间的浪费问题。
专利201010117002.0中公开了一种洗衣机的控制方法，所述洗衣机包括第一洗涤桶和第二洗涤桶，所述方法包括步骤：接收将在所述第一洗涤桶中执行的、要求供水程序或排水程序的第一操作指令；确定在所述第二洗涤桶中是否正在执行相同的操作指令；当正在所述第二洗涤桶中执行相同的操作指令时，确定不能执行所述第一操作指令；在将要求所述供水程序或所述排水程序的相同的操作指令同时输入所述第一洗涤桶和所述第二洗涤桶中时，确定所述第一洗涤桶和所述第二洗涤桶中的哪一个具有较短的剩余洗涤时间；以及优先在剩余洗涤时间较短的洗涤桶中执行所述供水程序或所述排水程序。
针对多筒洗衣机的设计初衷多筒洗衣机的洗涤、脱水和排水过程是各自独立的，在某一个洗涤筒在进行相应的操作时是不需要考虑其他的洗涤筒的运行状态的。然而大多数家庭中，在放置洗衣机的位置只有一个下水管道，因此这种多筒洗衣机的不同洗涤筒需要共用同一段排水管进行排水。在正常情况下，不同洗涤筒的排水不会互相发生影响，但是当下水管道，或者上排水的排水泵发生故障的时候，非常容易发生其他洗涤筒的洗涤水从排水管回流到该洗涤筒内的情况。特别是上下排布的洗涤筒，非常容易出现上洗涤筒内的洗涤水从下洗涤筒的排水管路倒灌到下洗涤筒的情况，不但污染了筒内的衣物，也容易造成漏水等故障。
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，提供一种衣物处理装置排水控制方法及多筒衣物处理装置，解决了多筒衣物处理装置在使用共用的排水管路排水时，其他洗涤筒内的洗涤水返流到洗涤筒内，而造成衣物污染的问题，特别是避免了上下布置的洗涤筒在进行排水或者脱水工作时，上洗涤筒内的洗涤水向下洗涤筒内倒灌的问题。
为了实现该目的，本发明采用如下技术方案：
一种衣物处理装置排水控制方法，所述衣物处理装置至少包括第一洗涤筒和第二洗涤筒，第一洗涤筒和第二洗涤筒的排水管路相通，各自独立控制排水管路的开闭；第一洗涤筒到达排水过程时，判断第二洗涤筒的排水管路是否打开，若是，则等待第二洗涤筒排水管路关闭后再打开第一洗涤筒的排水管路；否则，则打开第一洗涤筒的排水管路。
进一步地，第一洗涤筒到达排水过程时，若第二洗涤筒的排水管路打开，并且排水过程正在进行中，则等待第二洗涤筒排空并关闭第二洗涤筒的排水管路后再打开第一洗涤筒的排水管路；
优选地，待第一洗涤筒内的洗涤水排空后，第二洗涤筒的排水管路能打开。
进一步地，第二洗涤筒到达排水过程时，判断第一洗涤筒的排水是否正在进行，若是，则等待第一洗涤筒排空后打开第二洗涤筒排水管路；否则，则打开第二洗涤筒的排水管路。
进一步地，第一洗涤筒由低转速脱水向高转速脱水的升速过程中，关闭第二洗涤筒排水管路。
优选地，第一洗涤筒脱水稳定在高转速脱水状态下时，第二洗涤筒排水管路能打开。
进一步地，第一洗涤筒预由低转速脱水向高转速脱水的升速切换前，判断第二洗涤筒排水管路是否关闭，若是，则第一洗涤筒由低转速脱水向高转速脱水转变，最终达到高转速脱水；否则第一洗涤筒保持低转速脱水状态。
进一步地，第一洗涤筒预由低转速脱水向高转速脱水的升速切换前，若第二洗涤筒的排水管路打开，并且排水过程正在进行中，则等待第二洗涤筒排空并关闭第二洗涤筒的排水管路后，第一洗涤筒再由由低转速脱水向高转速脱水转变，最终达到高转速脱水。
一种应用上述任一所述的衣物处理装置排水控制方法的多筒衣物处理装置，所述多筒衣物处理装置至少包括第一洗涤筒和第二洗涤筒，第一洗涤筒和第二洗涤筒的排水管路分别由独立的控制装置控制各自排水管路的通/断状态的切换，并且第一洗涤筒和第二洗涤筒 的排水管路汇接于同一总排水管路，并通过该总排水管路将洗涤水排出机体。
进一步地，所述多筒衣物处理装置为上排水衣物处理装置，所述总排水管上设置有排水泵，所述排水泵用于将总排水管中的洗涤水泵出机体，完成衣物处理装置的排水过程。
进一步地，所述控制装置为排水阀，所述第一洗涤筒的排水管路和第二洗涤筒排水管路，通过设置在各自排水管路上的排水阀来分别控制各自排水管路的通断。
进一步地，所述第一洗涤筒的排水高度高于所述第二洗涤筒的排水高度
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。
本发明在为多筒衣物处理装置中，特别设置了针对排水过程的控制方法。增加了在洗涤筒即将进行排水操作时，需要针对其他洗涤筒的排水管路的开/闭状态进行调整的控制方法。对不同的排水过程进行精细化操作，保证在不同的排水状态下，都能够切实避免出现不同洗涤筒内的洗涤水混流，或者上洗涤筒内的洗涤水倒灌到下洗涤筒内的情况的出现。特别是在容易造成水流倒灌的下洗涤筒的控制上，增加了在其排空后及时关闭排水阀的控制过程，降低了上洗涤筒排水时洗涤水倒灌到下洗涤筒的风险。
不但如此，本发明还对不同转速的脱水过程的排水管的开/闭状态的切换做了有针对性的设计，使洗涤筒在脱水状态下由于转速的不同而造成排水量变化时，也不会出现洗涤水倒灌至洗涤筒的状况。
使用本发明的控制方法的多筒衣物处理装置，通过在不同洗涤筒各自的排水管路上增加排水管路通/断的控制装置，独立控制各自的排水管路的通/断状态切换，并优化各自的排水和脱水过程的控制方法，实现了不同的洗涤筒既共用同一个排水泵进行排水，又不会出现洗涤水倒灌的问题。
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。

如图1至图7所示，本发明公开了一种衣物处理装置排水控制方法及多筒衣物处理装置，所述衣物处理装置至少包括第一洗涤筒8和第二洗涤筒7，第一洗涤筒8和第二洗涤筒7的排水管路相通，各自独立控制排水管路的开闭；第一洗涤筒8到达排水过程时，判断第 二洗涤筒排水管路5是否打开，若是，则等待第二洗涤筒排水管路5关闭后再打开第一洗涤筒排水管路3；否则，则打开第一洗涤筒排水管路3。本发明解决了多筒衣物处理装置在使用共用的总排水管路2排水时，其他洗涤筒内的洗涤水返流到洗涤筒内，而造成衣物污染的问题，特别是避免了上下布置的洗涤筒在进行排水或者脱水工作时，上洗涤筒内的洗涤水向下洗涤筒内倒灌的问题。
实施例1
如图1至图3所示，本实施例中揭示了一种衣物处理装置排水控制方法。本实施例中的所述衣物处理装置为多筒洗衣机，至少包括第一洗涤筒和第二洗涤筒，第一洗涤筒和第二洗涤筒洗涤、脱水和排水过程是各自独立的，并各自通过第一洗涤筒排水管路和第二洗涤筒排水管路进行排水，第一洗涤筒和第二洗涤筒的排水管路分别由独立的控制装置控制各自排水管路的通/断状态的切换。并且第一洗涤筒和第二洗涤筒的排水管路相通，并汇接于同一总排水管路，并通过该总排水管路将洗涤水排出机体。本实施例中的排水装置是设置在不同洗涤筒的各自排水管路上的用于控制其通断的排水阀。
当第二洗涤筒的排水管路打开时，第二洗涤筒与总排水管路处于连通状态。此时，如果总排水管路内的洗涤水由于某种原因不能排出，则当总排水管路内的洗涤水液面升高到高于第二洗涤筒的控制装置的高度时，就非常容易造成洗涤水从总排水管路中顺着第二洗涤筒排水管路倒灌如第二洗涤筒内。造成第二洗涤筒内污染或者漏水的情况出现。
因此如图1所示，本实施例中，当第一洗涤筒到达排水过程时，则判断第二洗涤筒的排水管路是否打开，若是，则等待第二洗涤筒排水管路关闭后再打开第一洗涤筒的排水管路；否则，则打开第一洗涤筒的排水管路。也就是说为了避免第一洗涤筒内的洗涤水倒灌入第二洗涤筒，如果第二洗涤筒的排水管路处于打开状态，则必须先关闭第二洗涤筒的排水管路才能再执行第一洗涤筒的排水操作。这样也就保证了在第一洗涤筒在执行排水过程时，第二洗涤筒的排水管路与总排水管路处于截断的状态，也就消除了洗涤水从总排水管路流入第二洗涤筒排水管路的风险。
进一步地，如图2所示，当第一洗涤筒到达排水过程时，若第二洗涤筒的排水管路打开，并且排水过程正在进行中，则第一洗涤筒等待第二洗涤筒排空并关闭第二洗涤筒的排水管路后再打开第一洗涤筒的排水管路。这样的设置首先优先保证第二洗涤筒排水过程的顺畅完成，在本发明的设计总体思路下，进一步减少了第二洗涤筒的排水阀的开闭次数，延长第二洗涤筒的排水阀的使用寿命。在这种情况下，待第一洗涤筒内的洗涤水排空后， 第二洗涤筒的排水管路能够再次打开。
进一步地，在洗涤筒上下设置的多筒衣物处理装置中，第一洗涤筒的排水高度高于所述第二洗涤筒的排水高度，本发明在这种设置中，第二洗涤筒到达排水过程时，需要进行进一步的判断。如图3所示，第二洗涤筒到达排水过程时，判断第一洗涤筒的排水是否正在进行，若是，则等待第一洗涤筒排空后打开第二洗涤筒排水管路；否则，则打开第二洗涤筒的排水管路。在本排水过程中，第二洗涤筒等待第一洗涤筒排空之后再进行排水，由于第一洗涤筒的排水高度较高，因此在第一洗涤筒排空的情况下，只要保证第二洗涤筒内的洗涤水能够顺利排出就不会发生洗涤水倒灌的情况，不需要再次关闭第一洗涤筒的排水阀。在这样的控制过程减少了第一洗涤筒的排水阀的开闭次数，延长了第一洗涤筒的排水阀的使用寿命。
实施例2
如图4和图5所示，本实施例是对实施例1中的洗涤筒有执行脱水程序的情况的进一步补充。在本实施例中，第一洗涤筒由低转速脱水向高转速脱水的升速过程中，关闭第二洗涤筒排水管路。第一洗涤筒脱水稳定在高转速脱水状态下时，第二洗涤筒排水管路能打开。这是因为衣物处理装置在执行脱水程序时，在经历低转速向高转速的升速过程时，排水的水量将显著增加，此时是脱水阶段排水最集中的时段。因此，与实施例1类似的，为了防止洗涤水从排水管路中倒灌回洗涤筒，对各洗涤筒的排水管路也进行与实施例1类似的控制。
如图4所示，第一洗涤筒预由低转速脱水向高转速脱水的升速切换前，判断第二洗涤筒排水管路是否关闭，若是，则第一洗涤筒由低转速脱水向高转速脱水转变，最终达到高转速脱水；否则第一洗涤筒保持低转速脱水状态。也就是说为了避免第一洗涤筒内的在脱水状态下从低速脱水阶段向高转速脱水阶段切换过程中，洗涤水倒灌入第二洗涤筒，如果第二洗涤筒的排水管路处于打开状态，则必须先关闭第二洗涤筒的排水管路才能再执行第一洗涤筒的脱水升速排水操作；否则的话，第一洗涤桶就需要继续保持低转速脱水状态，保持较少的排水量。这样也就保证了在第一洗涤筒在脱水升速过程中排水量增大时，第二洗涤筒的排水管路与总排水管路处于截断的状态，也就消除了洗涤水从总排水管路流入第二洗涤筒排水管路的风险。
进一步地，如图5所示，若第一洗涤筒预由低转速脱水向高转速脱水的升速切换前，若第二洗涤筒的排水管路打开，并且排水过程正在进行中，则等待第二洗涤筒排空并关闭 第二洗涤筒的排水管路后，第一洗涤筒再由由低转速脱水向高转速脱水转变，最终达到高转速脱水、这样的设置首先优先保证第二洗涤筒排水过程的顺畅完成，在本发明的设计总体思路下，进一步减少了第二洗涤筒的排水阀的开闭次数，延长第二洗涤筒的排水阀的使用寿命。在这种情况下，待第一洗涤筒稳定在高转速脱水状态时，第二洗涤筒的排水管路能够再次打开。
实施例3
如图6所示，本实施例揭示了一种使用上述实施例所述的衣物处理装置排水控制方法的多筒衣物处理装置。
如图6所示，该衣物处理装置包括壳体9，壳体9内至少设置有第一洗涤筒8和第二洗涤筒7。如图中所示，所述第一洗涤筒8位于所述第二洗涤筒7的上部，其第一洗涤筒8的排水高度高于所述第二洗涤筒7的排水高度。
本实施例的多筒衣物处理装置为上排水衣物处理装置，所述总排水管2上设置有排水泵4，所述排水泵4用于将总排水管2中的洗涤水泵出机体，完成衣物处理装置的排水过程。第一洗涤筒的排水管路3和第二洗涤筒的排水管路5分别由独立的控制装置控制各自排水管路的通/断状态的切换。如图中所示，所述控制装置为排水阀，所述第一洗涤筒的排水管路3和第二洗涤筒排水管路5，通过设置在各自排水管路上的第一洗涤筒排水阀1和第二洗涤筒排水阀6来分别控制各自排水管路的通断。第一洗涤筒排水管路3和第二洗涤筒排水管路5汇接于同一总排水管2，并通过该总排水管2将洗涤水排出机体。
本实施例中的多筒衣物处理装置采用上述实施例的排水和/或脱水的控制方法，只需要使用一个排水泵，就能实现不同的洗涤筒在各自独立的排水过程中不会出现洗涤水倒灌的问题。不需要额外增加其他的排水泵或者进行下水的改造，降低了多筒衣物处理装置的安装成本。
实施例4
如图7所示，本实施例3的多筒衣物处理装置的补充。本实施与实施例3的区别在于，本实施例中的衣物处理装置为下排水，没有安装排水泵，第一洗涤筒排水管路3和第二洗涤筒排水管路5汇接于同一总排水管2，并通过该总排水管2将洗涤水排出机体。上下排布的第一洗涤筒8和第二洗涤筒7。同样采用上述实施例所采用的排水和/或脱水的控制方法，使用设置在各自排水管路上的第一洗涤筒排水阀1和第二洗涤筒排水阀6来分别控制各自排水管路的通断。实现不同的洗涤筒在各自独立的排水过程中不会出现洗涤水倒灌的问题。
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。
