Description

一种洗干一体机的控制方法 技术领域
本发明属于家电领域，具体地说，涉及一种洗干一体机的控制方法。
背景技术
洗干一体机为在同一机体内同时具有洗涤和烘干的功能。一般滚筒洗干一体机的连接管是洗涤水和冷凝水共用一个排水管路，其一端连接烘干出水口，另一端连接洗涤出水口。
这一结构所带来的问题是，洗涤工作时，筒内产生的洗涤水随管路进入泵体内排出机体外部，但部分洗涤水或洗涤水产生的泡沫会进入烘干筒管路，污染正在进行烘干的衣物，影响烘干筒的工作。烘干工作时，烘干过程中的热风进入管道，降低了热气的循环效率，影响烘干的效率并增加能耗。
一般的三通结构不能实现洗涤与烘干的分离；对洗涤水管路和冷凝水管路分别设置开关装置，不但增加了控制过程中的难度，易产生故障，还增加了洗干一体机的成本；洗涤水和烘干水分别使用不同的水泵进行排水作业，增加了成本和总体能耗现有技术。
针对上述问题，可通过在烘干排水管路中增加单向通过的结构或阀门装置等方式解决，其中水封结构结构简单且能够实现隔离的目的，但水封结构中的存留水易被排水装置带走而失去水封的作用，因而如何使水封结构保持其应有的作用亟待解决。
有鉴于此特提出本发明。

如图1至图6所示，本发明涉及一种洗干一体机的控制方法，所述洗干一体机具有如下所述的水路结构。
图1-图3为本发明的一个实施例，图4-图6为本发明的另一实施例。
如图1及图4所示，所述洗干一体机为双筒设置，上筒1及下筒2为上下重叠设置，所述上筒1具有上排水管路11，所述下筒2具有下排水管路21，优选方案为上筒1为烘干筒，下筒2为洗涤筒，由此得到，上排水管路11中排出上筒烘干时产生的冷凝水，下排水管路21排出下筒洗涤时产生的洗涤水。
在上筒进行烘干时，冷凝器12对烘干风中的水分进行冷凝，冷凝过程产生的冷凝水通过上排水管路11排出，所述冷凝器12还具有冷凝器过滤装置13，所述冷凝器过滤装置13在过滤后需要进行清洁，在冷凝器过滤装置13处还设有冲洗管路14，用于冷凝器过滤装置13的清洁，所述冲洗管路14通过冲洗阀141的开启和关闭产生冲洗水，所述冲洗管路14产生的冲洗水及冷凝水均通过上排水管路11排出。
所述下筒在进行洗涤时，产生的洗涤水在需要排水时，洗干一体机下设的排水泵3会将洗涤水排出机体外。
所述洗干一体机的排水泵3具有进水腔室31，所述进水腔室31具有多个进水口，多个进水口分别与不同管路进行连接，进水腔室31的多路进水均通过总排水管路32排出机体外。
所述上筒1的上排水管路11与其中一个进水口连接并与进水腔室31连通，所述下筒的下排水管路21与另一进水口连接并与进水腔室31连通。
所述下筒为洗涤筒，在洗涤过程中，洗涤水中具有因添加洗涤剂而产生的泡沫，且在洗涤过程中会产生臭气会通过管路而扩散至其他位置。
由于上筒1及下筒的排水通过同一排水泵3进行操作，并由于同时连通进水腔室31而使得上排水管路11和下排水管路21而相互连通，因而有必要在上排水管路11设置隔离装置使得上筒和下筒隔离，放置下筒产生的泡沫或臭气通过管路扩散至烘干筒而污染已经洗干净的衣物。
所述洗干一体机还具有主控系统，在排水管路中设置隔离装置后，主控系统根据上筒、下筒及排水泵的工作状态，对隔离装置进行控制。
实施例一
本实施例通过在上排水管路11设置水封结构111形成水封将上筒及下筒隔离。
如图1所示，在上排水管路11中部设置有水封结构111，所述水封结构111为局部弯折结构，液体积存在局部弯折结构的底部，可封堵管路，使气体或泡沫等不能通过。
优选地，如图2所示，所述局部弯折结构为U形弯管，所述U形弯管一端管体延伸向上，另一端管体再次弯折向下，所述U形弯管底部可积存液体形成水封。
水封结构111形成隔离是由管路中的水积聚在弯管底部而形成，由于冷凝水的积聚产生的流动以及排水泵的作用，水封结构111会随排水泵3的工作而被抽走部分积水，造成水封结构111中的剩余水不能形成水封，上筒1与下筒2不能形成隔离而出现臭气及泡沫随管道进入其他位置的情况，因而主控系统需要在水封机构缺水时进行补水。
由于冷凝器过滤装置13具有冲洗管路14，冲洗管路14在清洁过滤装置时产生冲洗水与冷凝水一同排出，因而主控系统可控制冲洗阀141对水封结构111进行补水。
如图3所示，上筒及下筒的工作状态不同，主控系统具有不同的控制方法对水封结构进行补水操作，主控系统对上筒及下筒的工作状态进行判断后进行如下操作：
当下筒单独工作时，对下筒内的衣物进行洗涤操作，在洗涤过程中具有排水的阶段和不排水的阶段，在排水阶段，由于上排水管路11中的水封中具有积水形成水封，排水泵3在开启后产生负压带走一部分水封结构111中的积水，从而使水封结构中的水不足以形成水封。因而在洗涤排水后，排水泵3停止工作，主控系统控制冲洗阀141开启产生冲洗水，从上排 水管路11中流至水封结构111，重新使得水封结构中的水形成水封。
主控系统控制冲洗阀141开启时间T1对水封结构111进行补水，并保证在T1时间内补充后的水能够形成水封。
在上筒单独工作时，上筒在烘干过程中会产生冷凝水，冷凝水由于水量较小且产生于烘干的整个过程，因而冷凝水的排出则在管路中积聚至一定水量后开启排水泵3才排出。在冷凝水产生时，由于冷凝水为洁净水，可通过上排水管路11进入下筒2内等待排水泵3的开启。在冷凝水积聚至一定量时，排水泵3开启将冷凝水排出，此时，主控系统控制冲洗阀141开启产生冲洗水对冷凝器过滤装置13进行冲洗。
由于过滤装置具有附着物，在冲洗水进行冲洗时，附着物进过水流的冲刷而随冲洗水一同进入上排水管路11。此时的冲洗水因含有附着物而不能作为补充水，在排水泵3开启的状态下，含有附着物的冲洗水随冷凝水一同排出机体外。
在冷凝水排水结束且冷凝器过滤装置13冲洗干净后，排水泵3关闭，此时冲洗水为洁净水，主控系统在排水泵3停止工作后，继续保持冲洗阀141的开启，使得冲洗水补充入水封结构111形成水封。
主控系统在排水泵3停止工作后，继续保持冲洗阀141开启时间T2对水封结构111进行补水，并保证在时间T2内形成水封。
在更复杂的情况下，且为多数情况下均为上筒和下筒同时工作。为便于描述将下筒的工作状态分为排水阶段和非排水阶段，其中排水阶段为排水泵3开启状态下进行排水的阶段。
此时由于上筒的冷凝水由于水量小，下筒的洗涤水水量大，上筒及下筒同时工作时，冷凝水在下筒的排水阶段一同随洗涤水排出，在排出洗涤水时同时冲洗过滤装置排出冲洗水。
在非排水阶段上筒产生的冷凝水可直接进入下筒充当洗涤水，冷凝水的洁净度并不会污染衣物。
在非排水阶段，冲洗阀141不会开启，以保证过滤装置中的附着物不会流入下筒中污染衣物。
在排水阶段冲洗阀141开启，洗涤水、冷凝水及冲洗水进入排水泵3一同从排水总管排出机体外。在排水阶段结束后，水封结构111中的存留的水不足以形成水封，此时主控系统不关闭冲洗阀141，使得洁净的冲洗水进入水封结构111形成水封。
在排水泵3关闭后冲洗阀141继续开启时间T3对水封结构111进行补水。
需要说明的是，在上筒和/或下筒工作时，补水时间的长短可能会不同，且补水时间T1、T2、T3受到排水泵参数、排水管路管径、水封结构容积等设置的影响，在不同的洗干一体机内可能会有不同。在不具有水位检测等装置的情况下，主控系统所控制的补水时间可通过具体洗干一体机的参数进行试验进行确定，以保证在衣物处理装的个体设置差异中，水封结构及补水过程能够起到相应的作用。
优选方案为，所述水封结构111具有感应装置，当所述水封结构111中剩余水量不足以形成水封时，所述主控系统控制进行补水；所述水封结构111中剩余水量仍然能够形成水封时，则不需要补水，即为在下筒单独工作时仍能形成水封，则T1＝0；在上筒单独工作时仍能形成水封，则T2＝0；在上筒和下筒同时工作时仍能形成水封则T3＝0。
更优选地，所述U形弯管处具有水位检测装置，所述水位检测装置在低于设定水位时向主控系统反馈信号，所述设定水位为形成水封的临界水位。
实施例二
本实施例与上一实施例的区别在于，所述上排水管路11中设有排水阀112，所述主控系统根据上筒及下筒的工作状态控制排水阀112的通断以达到上下筒隔离的目的。
具体方案如图4及图5所示，在实施例一中的水封结构111由排水阀112代替。所述排水阀112在开启时可通过上筒1中的冷凝水及冲洗水，在没有冷凝水和/或冲洗水通过时处于关闭状态以保证下筒2的泡沫或臭气等扩散至上筒1。
根据上述排水阀112的设置，主控系统具有如图6所示的控制方法。
所述主控系统判断上筒及下筒的工作状态，根据上筒和下筒的工作状态具有如下控制方法：
所述主控系统检测到下筒单独工作时，主控系统保持排水阀112关闭，以保证上筒在不工作时不被下筒工作过程中产生的污染物所污染，此时上筒1及下筒始终保持隔离状态；
所述主控系统检测到上筒单独工作时，主控系统控制间歇开启排水阀112，由于冷凝水水量较小，主控系统在冷凝水积聚到一定量时进行排水，主控系统开启排水阀112和排水泵3，排出冷凝水，此时根据需要开启冲洗阀141对冷凝器过滤装置13进行清洁，并同时排出冲洗水，在冷凝水排水结束后冲洗阀141关闭，排水泵3停止作业，主控系统关闭排水阀112；
所述主控系统检测到上筒工作与下筒同时工作时，主控系统在排水泵3开始工作时开启排水阀112，即为在下筒的排水阶段，排水泵3开启时，主控系统开启排水阀112使得上筒1 产生的冷凝水和/或冲洗水随洗涤水一同排水机体，在排水结束后主控系统关闭排水阀112。
优选地，所述排水阀112具有压力传感器，主控系统通过压力传感器反馈信号进行通断控制，压力达到设定值主控系统控制排水阀112开启。
在上述两个实施例中，所述洗干一体机的设置方式可以为单一筒，所述单一筒同时具有洗涤和烘干功能，洗涤和烘干功能具有相应的排水管路；还可以为双筒并列设置，并具有相同或不同的功能，通过设置水封结构或排水阀等隔离结构实现双筒的隔离；上下设置的双筒还可以为上筒为洗涤筒，下筒为烘干筒，烘干筒的排水管路设置隔离结构并通过主控系统进行相应的控制。
本发明的友谊效果可以总结为：在洗干一体机的管路上设置水封结构或阀体，可将洗涤和烘干的水气分离，互不干扰，既防止了洗涤水污染烘干的衣物，又增加了烘干过程中的热效率；洗干一体机的控制方法增加了水封结构的补水过程，保证了水封结构中有足够的水形成水封，保证上筒和下筒间的隔离；以冲洗过滤装置的冲洗水作为补充水封装置，在不增加机体额外结构的情况下，既能满足过滤装置的清洁，又能使得水封结构的密封；水封结构设置为U型弯管，结构简单，加工难度小；排水阀通过主控系统的通断设置即可实现上下筒隔离，易于实现。
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。
