一种洗衣机的自动投放系统及控制方法 技术领域
本发明属于衣物处理设备领域，具体地说，涉及一种洗衣机的自动投放系统及控制方法。
背景技术
消费者对于洗衣机自动程度需求变高，市场存在多种洗衣添加剂用来改善洗衣效果，例如抗皱剂，专门用来减少洗衣完成后衣服褶皱问题；纤维素酶：可用来增加衣服的洗净比，除这几种外市场还存在很多洗衣添加剂，这也是洗衣的需求所在。现市场存在最多的自动投放还是单一液体投放，而且多为内置式洗衣液存放腔，随着市场对多种洗衣添加剂需求的增加，市场洗衣机产品显然无法满足消费者需求。一方面，多种液体自动投放原理会更复杂、元器件在盘座内部的布局要求会更高；另一方面，多种液体意味着需要容积更大，原内置式容腔显然不能满足条件；第三，原内置式洗衣液存放腔，存在诸多缺点，例如灌装不易观察且需要专门设备及程序检测存留液体，不仅自动投放设备成本高且存放液体体积有限，很难在市场中得到积极响应。
中国申请CN201810637372.3提出了一种固定式多品类抽液装置，包括主体托架、抽液总成、大抽屉总成、控制线路板、液体包装盒和锁定装置。所述抽液总成、控制线路板和锁定装置安装于所述主体托架之上，所述抽液总成内设有泵送装置，所述大抽屉总成置于所述主体托架内，所液体包装盒置于所述大抽屉的安装槽内，所述抽液总成与所述大抽屉总成扣合构成一个整体箱体，所述液体包装盒置于所述大抽屉总成内的安装槽中，所述控制线路板、泵送装置、锁定装置和洗衣机之间电连接。所述控制线路板接收洗衣机的相关指令，再按相关指令要求来控制所述泵送装置和锁定装置工作。
上述抽液装置可以实现多种液体耗材的自动抽液和投液，在抽液过程中液体耗材在泵送装置的吸力作用下经过泵送装置进入投放管路，在水流的带动下进入投液过程，但在衣物处理设备领域，高浓度的衣物处理剂经过泵送装置后会对泵送装置产生腐蚀，严重影响泵送装置的工作效率和使用寿命，降低自动投液效率和用户的使用体验。
有鉴于此特提出本发明。

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“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”、“接触”、“连通”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；可以是机械连接，也可以是电连接；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所示的洗衣机的自动投放系统，包括第一管路19、第二管路16、缓冲装置、储液装置20和泵送装置15，所述第一管路19和第二管路16的进液端分别与洗衣机的进水管路3相连，第一管路19和第二管路16的出液端分别与缓冲装置相连，所述储液装置20通过切换阀与第一管路19相连，所述泵送装置15设置在第二管路16上。
具体的，如图2-5所示，所述储液装置20呈柱状或者盒状，设置在所述洗衣机的外部或 者内部，具有用来容纳衣物处理剂的储液腔室，所述储液装置20上开设有出液口，储液口上设置接口21，接口21上连接有出液管路22，出液管路22与第一管路19通过切换阀连通。优选所述切换阀为三通阀。所述储液腔室上设置可翻转的上盖，用来添加衣物处理剂；或者不设置上盖，在添加衣物处理剂前将储液装置20从洗衣机上取下，从储液腔室的出液口添加衣物处理剂，此时储液装置20至少与出液口相对的侧边为水平端面，便于灌装衣物处理剂时将储液装置20放置于水平面，方便用户进行灌装操作。所述储液腔室采用透明材料，用户通过肉眼即可观察储液腔室中的衣物处理剂是否用尽，可快速观察何时需要灌装。
如图2所示，所述缓冲装置具有一缓冲腔室9，设置在洗衣机的内部，优选设置在洗衣机的盘座23的下方，用来容纳衣物处理剂和水的混合溶液，所述缓冲腔室9与洗衣机的洗涤桶相连通，缓冲腔室9中的水和衣物处理剂的混合液流入洗涤桶中。通过设置缓冲腔室9一方面可以使水流与衣物处理剂在缓冲腔室9中稀释并混合均匀后进入洗涤腔室，增大洗净效率，另一方面防止进水过程中溅水。一种可实现的方式为所述缓冲装置为洗涤剂分配器盒或集成在洗涤剂分配器盒上的腔室，当储液腔室中的衣物处理剂不够时，用户还可以将洗涤剂分配器盒抽出后手动添加衣物处理剂。
如图2所示，所述泵送装置15优选设置在洗衣机的盘座23的下方，用来将储液装置20中的衣物处理剂吸入到第一管路19中，优选所述泵送装置15为电磁泵，衣物处理剂的具体投放量可以通过洗衣机的电脑板程序对于电磁泵运行时间的长短来控制，通过控制泵旋转圈数进而对投放液体精确控制衣物处理剂的具体投放量。
所述第一管路19和第二管路16优选设置在洗衣机的盘座23的下方，第一管路19和第二管路16的进液端分别与洗衣机的进水管路3相连，第一管路19和第二管路16的出液端分别与缓冲装置相连，所述储液装置20通过切换阀与第一管路19相连，所述泵送装置15设置在第二管路16上。所述进水管路3连通市政水源1，在所述进水管路3上设置第一给水阀2用来控制进水管路3的通断。所述切换阀与缓冲装置之间还设有单向阀18防止缓冲装置中的水回流至第一管路19中。本实施例通过将泵送装置15设置在独立的第二管路16上，在吸液过程中衣物处理剂不会进入到泵送装置15中，从而避免高浓度的衣物处理剂腐蚀泵送装置15，有效提高泵送装置15的使用寿命以及吸液和投液的精确度。同时，将泵送装置15设置在第二管路16上，在吸液之前的进液排气过程中，进水管中的水流入第二管路16中直到将第二管路16充满从而达到排尽空气的目的。在后续的吸液过程中，充盈在第二管路16中的水始终经泵送装置15流入缓冲装置中，既保证管路的密闭性又避免高浓度的衣物处理剂对泵送装置15直接造成腐蚀。即时有少量衣物处理剂进入第二管路16，在大量水的稀释作用下 对泵送装置15的腐蚀作用也可忽略不计。
进一步的，所述储液腔室的内部被分隔成若干独立的小腔室，若干所述小腔室的出液管路22分别与第一管路19相连通，至少一个所述小腔室的出液管路22通过切换阀与第一管路19相连。
具体的，如图4所示，所述储液腔室的内部被隔板/挡筋27分成若干的小腔室，若干所述小腔室的容积相同或不同，用来容纳具有不同功效的衣物处理剂。若干所述小腔室上分别开设出液口，出液口上分别设置接口21，接口21分别连接出液管路22，至少一个所述小腔室的出液管路22通过切换阀与第一管路19相连，其它小腔室的出液管路22上可通过设置单向阀18来控制衣物护理剂的流向。若干所述小腔室均可采用透明材质，并在腔室壁上添加用来区分不同衣物护理剂的颜色、符号、图案或文字。
进一步的，所述储液腔室包括主洗腔室5和辅洗腔室，所述主洗腔室5的出液管路22通过第一切换阀10与所述第一管路19相连通；所述辅洗腔室的出液管路22通过第二切换阀11与所述第一管路19相连通；还包括第三管路7，所述第三管路7的进液端与所述辅洗腔室的出液管路22相连，出液端与所述缓冲腔室9相连。
具体的，如图1、4所示，所述储液腔室被隔板分成主洗腔室5和至少一个辅洗腔室，所述辅洗腔室用来容纳常用的衣物护理剂，如洗涤剂，辅洗腔室中用来容纳不常用的衣物护理剂，如柔顺剂、彩漂剂等。由于主洗腔室5中容纳的衣物护理剂的用量大，因此将主洗腔室5的容积设置成大于辅洗腔室的容积。所述主洗腔室5的出液管路22通过第一切换阀10与所述第一管路19相连通；所述辅洗腔室的出液管路22通过第二切换阀11与所述第一管路19相连通。从而可以实现多种衣物护理剂的自动投放。还包括第三管路7，所述第三管路7的进液端与所述辅洗腔室的出液管路22相连，出液端与所述缓冲腔室9相连。由于辅洗腔室中的衣物护理剂使用频率较低，衣物护理剂长时间残留在第二切换阀11中会造成切换阀干涸堵塞，通过设置第三管路7，可以在投液过程中，使水流和衣物护理剂通过第三管路7进入到缓冲腔室9中，从而对第二切换阀11起到反冲洗的作用。由于辅洗腔室中的衣物护理剂使用频率较低，残留在第二切换阀11中的衣物处理剂干涸后会堵塞第二切换阀11，因此通过设置第三管路7来将第二切换阀11上残留的衣物护理剂冲洗干净，在第三管路7上还设有单向阀18防止缓冲腔室9中的液体回流至第三管路7中。在辅洗腔室的出液口与第三管路7的进液端之间也设有单向阀18来防止通过第三管路7进行投液的过程中水流进入到辅洗腔室中。
优选的，如图1所示，所述辅洗腔室包括第一辅洗腔室6和第二辅洗腔室8，所述第一 辅洗腔室6的出液管路22通过第二切换阀11与所述第一管路19相连通，所述第三管路7的进液端与所述第一辅洗腔室6出液管路22相连，出液端与所述缓冲腔室9相连。
具体的，所述第一辅洗腔室6和第二辅洗腔室8容纳何种衣物处理剂可按照衣物护理剂的使用频率来确定。第二辅洗腔室8和第二辅洗腔室8的容积可设置为相同或不同。一种可实施的方式为当储液装置20呈柱状时，通过隔板沿储液装置20长度方向将容纳腔室平均分成两个独立腔室，其中一个腔室为主洗腔室5，另一腔室由另一隔板沿容纳腔室宽度方向分成两个独立的小腔室，其中一个小腔室为第一辅洗腔室6，另一小腔室为第二辅洗腔室8。所述第一辅洗腔室6的出液管路22通过第二切换阀11与所述第一管路19相连通，所述第三管路7的进液端与所述第一辅洗腔室6出液管路22相连，出液端与所述缓冲腔室9相连。因此可以实现三种衣物护理剂的自动投放。在通过第三管路7进行投液的过程中水和衣物护理剂的混合液通过第三管路7进入缓冲腔室9中对第二切换阀11进行反冲洗，此时第一辅洗腔室6的出液管路22还设置单向阀18防止在投液过程中水流进入到辅洗腔室中，第二辅洗腔室8的出液管路22上设置单向阀18来控制第二辅洗腔室8的进液管的开闭。
进一步的，如图1所示，还包括液体交换腔室4，所述液体交换腔室4设置在所述洗衣机的进水管路3和所述第一管路19之间。
具体的，所述液体交换腔室4可为一密闭腔室或设置在第一管路19的进液端的粗管路，在吸液过程中衣物处理剂在泵送装置15的作用下由第一管路19进入到液体交换腔室4中，在液体投放过程中洗衣机进水管路3中的水进入液体交换腔室4对衣物护理剂起到预溶解的作用。
进一步的，如图1所示，还包括第四管路14，所述第四管路14的进液端与所述洗衣机的进水管路3相连，出液端与所述缓冲装置相连。
具体的，所述第四管路14直接将洗衣机的进水管路3与缓冲装置相连，洗衣机进水管路3中的水可由第四管路14流入缓冲装置中，所述第四管路14上设置有单向阀18来控制水流流向。由于泵送装置15通过第二管路16相对于第一管路19独立设置，在进液排气或投液过程中，水源1打开后市政水可分别从第一管路19、第二管路16进入到缓冲装置中，但由于市政水压会出现不稳定的情况，当市政水压过高时，高压水流会对泵送装置15产生冲击，造成泵送装置15损坏，影响泵送装置15的使用寿命，通过设置第四管路14，且在第四管路14上设置单向阀18，当市政水压过高，达到预设水压值时，控制第四管路14上的单向阀18开启，进水管路3中的部分水流由第四管路14流入缓冲装置中从而达到了泄压的作用，对泵送 装置15起到了保护的作用。
进一步的，如图1所示，还包括第五管路13，所述第五管路13的进液端与所述洗衣机的进水管路3相连，出液端连接消毒液腔室12。
具体的，所述第五管路13将洗衣机的进水管路3和消毒液腔室12相连通，所述消毒液腔室12用来容纳消毒液用于洗涤桶的消毒清洗，所述消毒液腔室12与洗涤桶相连通，一种可实现的方式为所述消毒液腔室12集成在洗涤剂分配器盒上，方便用户添加消毒剂。通过设置单独的第五管路13以免消毒剂对衣物处理剂造成污染。所述第五管路13上还设置第二给水阀17来控制第五管路13的通断。
进一步的，所述第一管路19、和/或辅洗腔室的出液管路22、和/或第三管路7、和/或第四管路14上设置单向阀18，且单向阀18开启后水流方向按图1中所示的箭头所示的方向流动。
进一步的，如图2、3、5、8所示，所述洗衣机包括盘座23，所述盘座23上设置支架24，所述储液装置20可拆卸的设置在所述支架24上；所述支架24包括设置在所述盘座23上的底座28，所述底座28具有一延伸长度，所述底座28长边的边缘沿远离所述盘座23的方向延伸形成与所述底座28具有一定角度的靠板29，所述储液装置20可拆卸装配在所述底座28上。
具体的，如图4所示，所述储液装置20包括左盖25、右盖26、储液腔室，分别开制模具后，左盖25、右盖26分别与储液腔室进行熔敷，工艺完成后即可形成密闭腔且不可分离。储液腔室上侧面设置为水平端面，主要用于灌装时立于水平面，方便用户进行灌装操作。通过在左盖25、右盖26、储液腔室内部设置挡筋27的方式实现多个独立腔的划分，其中每个腔对应开设独立的出液口，出液口上分别设置接口21，洗衣机盘座23上对应设置有供所述接口21插入的插孔34，插孔34中分别设有与各个腔室的接口21相连接的出液管路22。
如图3、5、6、7所示，所述支架24包括一具有延伸长度的底座28，所述底座28设置在盘座23上，所述底座28具有一定厚度用来支撑所述储液装置20，所述底座28设置在所述盘座23靠近进水管路3的侧边且沿该侧边长度方向设置，所述底座28的长边的边缘沿远离所述盘座23的方向延伸形成与所述底座28具有一定角度的靠板29，所述储液装置20可拆卸装配在所述底座28上。由于盘座23靠近进水管路3的侧边倾斜设置且略低于洗衣机的上端面，将靠板29朝靠近盘座23边缘设置来保证储液腔室的装配稳定性；如图6、7所示，所述底座28的底面中心朝靠近所述盘座23的方向凸起形成中心柱体31，所述中心柱体31 的端部边缘全部/部分向外部翻折形成卡边32，所述盘座23上开设有与所述中心柱体31相匹配的安装腔35，所述安装腔35的底部开设与所述卡边32相匹配的卡槽。如图8所示，所述盘座23上对称设置第一螺孔36，如图7所示，所述底座28的底面与所述第一螺孔36相对的位置设置第二螺孔37，在对支架24进行装配的过程中，首先将中心柱体31伸入到安装腔35中，通过卡边32与卡槽配合预装在盘座23上侧，然后从盘座23下方分别从两个第一螺孔36打入两颗螺钉，螺钉与底座28上的第二螺孔37紧固，实现底座28与盘座23的稳固配合，并且在外部不能实现拆装，保证支架24的稳固性。如图4-7所示，所述底座28靠近两端的位置分别设置定位孔30，所述储液装置20的设有出液口的侧面与所述定位孔30相对应的位置设置定位柱33，储液装置20与支架24装配过程中，由定位柱33插入定位孔30中防止储液装置20晃动，同时各个腔室的出液口上连接的接口21与插孔34中的出液管路22相连接。在对衣物处理剂进行灌装时可将储液装置20整体竖直向上拔出，以实现对各种液体的灌装，灌装完成后竖直方向将储液装置20插入盘座23对应位置即可，操作比较便捷，大大提高灌装效率。
本实施例还提出了上述自动投放系统的控制方法，如图9所示的控制逻辑图，包括：通过控制所述切换阀的开启状态来控制所述自动投放系统的吸液和投液。
具体的，在吸液过程中，控制切换阀将储液装置20与泵送装置15之间的通路导通，此时储液腔室的出液管路22、第一管路19、第二管路16之间的通路导通，控制电磁泵启动，通过电磁泵的吸力将储液装置20中的衣物处理剂吸入到第一管路19上；在投液过程中，电磁泵关闭，控制切换阀将进水管路3与缓冲腔室9之间的通路导通，此时洗衣机的进水管路3、第一管路19与缓冲腔室9之间的通路导通，洗衣机的进水管路3中的水与第一管路19中的衣物处理剂混合后进入到缓冲腔室9并最终进入洗涤桶中。在吸液和投液过程中高浓度的衣物护理剂无需流入泵送装置15，从而避免对泵送装置15造成腐蚀。
进一步的，本实施例的自动投放系统的工作过程包括进液排气过程、吸液过程和投液过程，所述控制方法包括：进液排气过程，接收洗涤指令，控制洗衣机进水，控制切换阀将洗衣机的进水管路3与缓冲装置之间的通路导通，此时进水管中的水流进入到第一管路19和第二管路16中，达到第一预设时间后，此时第一管路19和第二管路16被水充满，气体被排尽，停止进水；
吸液过程，控制切换阀将储液装置20与泵送装置15之间的通路导通，控制泵送装置15开启，在泵送装置15的吸力作用下储液装置20中的衣物处理剂被吸入到第一管路19或液体 交换腔室4中，达到第二预设时间后，此时已经抽吸到需要投放的衣物处理剂的使用量，控制泵送装置15关闭；
投液过程，控制洗衣机进水，控制切换阀将洗衣机的进水管路3与缓冲装置之间的通路再次导通，进水管中的水与抽吸到第一管路19/液体交换腔室4中的衣物护理剂混合后流入缓冲装置中，并由缓冲装置流入洗衣机的洗涤桶中，达到第三预设时间后，达到洗涤程序需要的进水量后停止进水。
进一步的，当所述储液腔室包括主洗腔室5和辅洗腔室时，当吸液过程中辅洗腔室中的衣物处理剂进入第一管路19/液体交换腔室4时，在投液过程中控制第一管路19上的单向阀18关闭，第三管路7上的单向阀18开启，使得投液过程中水和衣物处理剂的混合液体通过第三管路7进入到缓冲腔室9中，从而第二切换阀11进行冲洗避免第二切换阀11中残留的衣物处理剂干涸将第二切换阀11堵塞。
进一步的，吸液过程中，若检测衣物处理剂从第二切换阀11进入第一管路19，则在投液过程中控制第二切换阀11将第一管路19与第三管路7之间的通路导通。
由于辅洗腔室的出液管路22通过第二切换阀11与第一管路19连通，且辅洗腔室中的衣物处理剂使用频率不高，残留在第二切换阀11中的衣物处理剂干涸后会造成第二切换阀11堵塞，因此当辅洗腔室中的衣物处理剂从第二切换阀11流入第一管路19时，在投液过程中需控制第二切换阀11将第一管路19与第三管路7导通，且第一切换阀10将第一管路19与进水管路3导通，进水管中的水由第一管路19进入第三管路7，从而对第二切换阀11进行反冲洗，然后由第三管路7进入缓冲腔室9中。
进一步的，当接收消毒指令，控制进水管路3中的水由第五管路13进入到消毒液腔室12，与事先投放在消毒液腔室12中的消毒液混合后进入到洗涤桶中，达到第四预设时间后达到预设进水量，停止进水，开始执行对洗涤桶的消毒清洗。
进一步的，所述进水管路3上设置水压检测装置，所述控制方法包括：在排气进液或投液过程中，当水压检测装置检测进水管路3中的水压大于预设水压时，控制第四管路14上的单向阀18开启，进水管路3中的水进入第一管路19、第二管路16、第三管路7和第四管路14中，并分别进入缓冲装置后流入洗涤桶中，当水压检测装置检测水压值小于或等于预设水压时，控制第四管路14上的单向阀18关闭，进水管路3中的水进入第一管路19、第二管路16和第三管路7中，并分别进入缓冲装置后流入洗涤桶中。
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。
