具体实施方式
需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的技术特征可以相互组合，具体实施方式中的详细描述应理解为本申请宗旨的解释说明，不应视为对本申请的不当限制。
在本申请实施例的描述中，“上”、“下”、“顶”、“底”、“高度方向”方位或位置关系为基于附图1所示的方位或位置关系，需要理解的是，这些方位术语仅是为了便于描述本申请和简化描述，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申请的限制。
本申请实施例提供一种衣物处理设备，请参阅图1、图2以及图4，包括外桶30、内筒20、平衡装置10、注水组件40、偏心检测单元以及控制主板。内筒20转动地设置于外桶30内。平衡装置10包括多个沿内筒20 的周向布置且与内筒20连接的水箱组件12，也就是说，在内筒20转动过程中，水箱组件12会与内筒20一起转动。水箱组件12具有排水口12b，进入水箱组件12内的水，会从排水口12b排出，而不会长期封存在水箱组件12内。
偏心检测单元用于检测内筒20的负载偏心信息。一实施例中，负载偏心信息包括至少包括偏心位置，例如，负载偏心信息还可以进一步包括偏心质量。
偏心检测单元以及注水组件40均与控制主板电连接，控制主板配置为：根据负载偏心信息确定待注水的水箱组件12，并控制注水组件40向待注水的水箱组件12供水。需要说明的是，注水组件40可以一次只为一个水箱组件12供水，也可以同时为多个水箱组件12供水。
在洗涤阶段，内筒20转速很低，例如，在40转每分钟，而且是间歇性地转动，因此，无需对内筒20进行平衡，因此，洗涤阶段无需向储水腔121a注水。在脱水阶段开始之初，水箱121内基本不存水，如此，才能便于在脱水阶段根据内筒的负载偏心信息来向相应的水箱121注水。
本申请实施例的衣物处理设备，在脱水阶段，内筒20最开始低速转动，在短时间内即可加速到较高的转速，例如，800～1200转每分钟，在较大的转速下实现衣物离心脱水。如果内筒20在低速转动时就发生了负载偏心，偏心检测单元将检测到的负载偏心信息发送至控制主板，当控制主板确定需要对内筒20进行平衡时，则控制主板控制注水组件40主动向待注水的水箱组件12注水，例如，如果负载向图1的右侧偏心，注水组件40则向图1的左侧的水箱组件12注水，以注入的注水量和水箱组件12的整体质量共同抵抗内筒20的负载偏心质量。因此，即使在内筒20转速较低的情况下，注水组件40也能及时向对应的水箱组件12注水来抵抗内筒20的负载偏心质量，对内筒20起到较好的平衡作用。当内筒20转速逐渐增大， 只要内筒20出现负载偏心，控制主板均可以控制注水组件40主动向待注水的水箱组件12供水以抵抗内筒20的偏心，因此，本申请实施例的平衡装置10能够在内筒20全转速段对内筒20起到较好的平衡作用，有效地降低撞桶风险和降低振动噪声，改善用户体验感。
需要说明的是，一些实施例中，沿内筒20的径向，水箱组件12可以设置于内筒20和外桶30之间。另一些实施例中，沿内筒20的径向，水箱组件12也可以设置于内筒20的内部，如此，水箱组件12不会占用内筒20和外桶30之间狭小的安装空间，因此，不会增加内筒20的撞桶风险。
一些实施例中，排水口12b可以是一直处于打开状态。另一些实施例中，排水口12b能够选择性地打开或关闭，例如，在洗涤阶段，可以保持排水口12b关闭，防止洗涤水从排水口12b倒灌进入水箱组件12中。在脱水阶段开始之前，排水口12b处于打开状态，以使得开始脱水之前水箱组件12中基本不存水。
偏心检测单元的具体类型不限，只要能够检测到内筒的负载偏心即可。偏心检测单元可以采用现有技术中任一种用于检测内筒的负载偏心的元器件，在此不再赘述。
一实施例中，多个水箱121沿内筒20的周向均匀分布，即多个水箱121沿内筒20的周向均匀分布，由此，可以便于对在内筒20在转动过程中出现的负载偏心进行平衡调节。
需要说明的是，衣物处理设备可以是干衣机、洗干一体机、脱水机、洗衣机中的任一种或多种的集成。其中，内筒20的转动轴线可以沿竖直方向，例如，衣物处理设备可以是波轮洗衣机，内筒20的转动轴线也可以沿相对竖直方向倾斜一定的角度，例如，衣物处理设备可以是搅拌式洗衣机。平衡装置10的转动中心线与内筒20的转动轴线大致重合，也就是说，平衡装置10可以与内筒20同轴设置。
一些实施例中，请参阅图2，内筒20包括金属筒身21以及设置于金属筒身21下端的筒底22。金属筒身21由金属板卷绕而成。筒底22可以采用塑料材质，也可采用其他材质。
一些实施例中，请继续参阅图2，外桶30包括桶身31以及位于桶身31顶部的环形盖体32，环形盖体32从桶身31的顶端沿径向向内延伸。环形盖体32的内径小于内筒20的金属筒身21的内径，环形盖体32的中间区域形成衣物投放通道。
一些实施例中，请参阅图1，衣物处理设备包括箱体200，外桶30设置在箱体200内。
排水口12b选择性地打开或关闭的方式可以有多种，示例性地，一实施例中，请参阅图4、图5、图7、图11以及图12，平衡装置10包括浮子组件13，浮子组件13包括浮子132，浮子132能够在自身重力以及浮力的共同作用下在打开排水口12b的打开状态(参照图12)或在关闭排水口12b的关闭状态(参照图11)之间切换。
具体地，当衣物处理设备处于洗涤状态时，浮子132在洗涤水的作用下上浮并将排水口12b堵住。需要说明的是，当外桶30内的液位下降时，浮子132能够在自身重力作用下向下运动，此时，浮子132会打开排水口12b。由此使得每个水箱121的排水口12b能够选择性地打开或关闭。该实施例中，通过浮子132来实现排水口12b的打开或关闭，无需其他的驱动机构来控制浮子132的运动，结构简单、可靠性高。
一实施例中，请参阅图5和图6，浮子组件13包括安装支架131，安装支架131与内筒20保持相对静止，也就是说，安装支架131与内筒20之间没有相对运动。需要说明的是，由于水箱组件12与内筒20连接，即水箱组件12也是与内筒20保持相对静止，因此，安装支架131也与水箱组件12保持相对静止。安装支架131可以直接与水箱组件12连接，依靠 水箱组件12来为安装支架131提供安装支撑；也可以直接与内筒20等其它元器件连接，只要保证安装支架131不会相对于内筒20运动即可。
浮子132与安装支架131滑动配合，通过安装支架131的导向作用，避免浮子132在上下运动过程中发生大范围偏摆，使得浮子132在浮力的作用下能够可靠地封堵排水口12b，提升浮子132的工作可靠性。
安装支架131的具体结构形式不限，只要能够对浮子132起到导向作用即可。示例性地，一实施例中，请参阅图6、图11以及图12，安装支架131包括支架主体1311和导向杆1312，支架主体1311具有容纳空间131a，导向杆1312的至少一部分伸入容纳空间131a中且沿浮子132的运动方向延伸，也就是说，导向杆1312可以只有一部分结构位于容纳空间131a中，也可以全部结构位于容纳空间131a中。浮子132设置在容纳空间131a中且与导向杆1312滑动连接。该实施例中，将浮子132设置在容纳空间131a内，不仅可以对浮子132的运动起到更好的导向作用，还能对浮子132起到较好的保护作用。
需要说明的是，浮子132和导向杆1312的滑动连接方式不限，只要能够实现滑动连接即可。示例性地，一实施例中，请参阅图图11和图12，浮子132包括相互连接的套接部1321和堵头1322，堵头1322位于套接部1321靠近水箱121的一端，套接部1321背离堵头1322的一端设置有盲孔1321a，导向杆1312的端部伸入盲孔1321a内且能够在盲孔1321a内相对滑动，浮子132通过套接部1321与安装支架131滑动连接。需要说明的是，盲孔1321a的深度需要预留浮子132的运动行程，也就是说，在浮子132的整个运动行程内，导向杆1312的端部始终位于盲孔1321a内，不会从盲孔1321a中脱出。由于盲孔1321a不会贯穿浮子132，因此，不会影响浮子132对排水口12b的密封性能。
支架主体1311的具体结构形式不限，例如，一实施例中，请参阅图6， 支架主体1311包括支撑端板13111和多个连接板13112；多个连接板13112沿支撑端板13111的周向布置以围设呈一个中空的柱状体结构，中空的柱状体结构内形成容纳空间131a，浮子132能够从柱状体结构的远离支撑端板13111的一侧置入容纳空间131a内，导向杆1312凸出于支撑端板13111朝向容纳空间131a的一侧。
一些实施例中，支架主体1311还可以进一步包括环状筋板，多个连接板13112沿环状筋板的周向布置且连接于支撑端板13111和环状筋板之间。环状筋板能够改善各连接板13112的受力条件，提升各连接板13112的刚度和结构强度。在安装支架131直接与水箱121连接的实施例中，安装支架131可以通过环状筋板与水箱121连接，例如粘接、螺纹副配合等等。
需要说明的是，在安装支架131直接与内筒20连接的实施例中，安装支架131可以与内筒20的筒底22一体注塑成型。在安装支架131直接与水箱121连接的实施例中，安装支架131可以通过上述的各个连接板13112与水箱121连接，例如，粘接。
一实施例中，请参阅图4，水箱组件12包括相互连接的水箱121和管体122；管体122的顶端与水箱121连接，排水口12b设置于管体122的底端。具体地，水箱121具有入口12a、储水腔121a以及过流口121b，水流经入口12a进入水箱121内，排水时，水箱121中的水经过流口121b后进入管体122，并从管体122的底端的排水口12b流出。如此，水箱组件12在不与外桶30产生干涉的情况下，排水口12b可以尽量接近外桶30的底部，即使在外桶30中的水位较低时，也能够推动浮子132上浮而封堵排水口12b。
可以理解的是，在其它实施方式中，也可以不设置管体122，比如，可以在洗涤阶段控制外桶30中的水位保持在能够推动浮子132上浮的水位。
一实施例中，水箱121不低于金属筒身21的底端端部，也就是说，水 箱121的任何部位均不低于金属筒身21的底端端部。具体地，在水箱组件12设置于内筒20和外桶30之间的实施例中，如此，在内筒20转动过程中，避免水箱121与外桶30产生干涉。在水箱组件12设置于内筒20内的实施例中，水箱121基本不会影响筒底22的结构，可以在现有的内筒20结构上安装水箱121。
在水箱组件12设置于内筒20内的实施例中，水箱121的底部可以支撑在筒底22的边缘，如此，筒底22可以对水箱121起到一定的支撑作用，改善水箱121的受力条件。
在水箱组件12设置于内筒20内的实施例中，管体122的底端穿过筒底22，也就是说，管体122的底端所处的位置较低，便于更可靠地接触外桶30内的水。
一具体地实施例中，请参阅图12，管体122沿水流流动方向的末端处对应的内壁形成有台阶面122a，浮子132的至少一部分伸入排水口12b内且与台阶面122a抵接。台阶面122a可以提高浮子132的封堵效果。
一具体地实施例中，请继续参阅图11和图12，堵头1322的周向表面形成有抵接面1322a。当浮子132处于封堵排水口12b的关闭状态时，堵头1322远离套接部1321的一端的端面与台阶面122a抵接，抵接面1322a与管体122位于排水口12b周侧的底端面抵接。也就是说，堵头1322可以同时在排水口12b的内外两侧进行封堵，由此，可以进一步提高封堵效果。
一实施例中，请参阅图10，水箱121的底壁设置有过流口121b，过流口121b位于储水腔121a的底壁靠近内筒20转动轴线一侧的边缘处。当内筒20旋转时，储水腔121a中的水流会在离心力的作用下向储水腔121a的外侧集中，因此，将排水口12b的设置位置尽量靠近储水腔121a的内侧，如此可以尽量地将水流保持在水箱121中，从而可以进一步延长水流在水箱组件12中的停留时间。
一实施例中，请参阅图10和图13，储水腔121a具有多个沿竖向分层设置的子腔室121a′以及连通相邻两子腔室121a′的过水口1212a，多个子腔室121a′依次连通，入口12a与沿水流流动方向的第一个子腔室121a′连通，排水口12b与沿水流流动方向的最后一个子腔室121a′连通。
由于储水腔121a具有多个沿竖向分层设置且依次连通的子腔室121a′，当水流进入储水腔121a后，需要依次流经各个子腔室121a′后才能最终到过流口121b，相当于延长了水流在储水腔121a内的流动路径和流动时间。假如在内筒20转速较低时出现了负载偏心，进入储水腔121a内的水由于具有较长的流动路径和流动时间，水流从进入储水腔121a后需要相对较长的时间才能达到过流口121b。可以理解的是，在脱水阶段，内筒20处于低速阶段的时间很短，水流在储水腔121a内的流动时间足以使得内筒20越过低速阶段，因此，在低速阶段内，注入储水腔121a内的水的质量基本都能充当平衡质量的作用，从而使得平衡装置10的平衡效果更好。而进入高速阶段以后，储水腔121a中的水受到较大的离心力，而紧贴储水腔121a径向向外的内表面，水流不易在重力作用下向下流动，由此使得储水腔121a中的水流留在储水腔121a中，而不会从排水口12b排出，负载偏心可得到大幅度的平衡，可以有效的减小衣物处理设备在脱水时的振动和噪音，降低内筒20的撞桶风险，提升用户体验感。
此外，将储水腔121a划分多个子腔室121a′的形式，能够使得储水腔121a内的水量分布相对均匀，减小储水腔121a内的水流的波动幅度，降低平衡装置10自身的振动和噪声；以及，当内筒20转动速度较高时，子腔室121a′能够阻挡水流顺着储水腔121a的内表面向上浮动，避免水流逆流而冲出入口12a。
一实施例中，请参阅图10和图13，水箱121包括箱壳1211、设置于箱壳1211中的至少一个隔板1212、设置于箱壳1211顶端的插接头1213， 所有的隔板1212将箱壳1211内的空间分隔为沿竖向分层设置的多个子腔室121a′，多个子腔室121a′之间通过过水口1212a连通。也就是说，隔板1212大致沿水平方向布置，当隔板1212的数量有多个时，多个隔板1212大致平行间隔设置。
过水口1212a的形成方式不限，例如，一实施例中，每一隔板1212的一部分边缘与箱壳1211的内壁间隔设置以形成过水口1212a，以使得多个子腔室121a′依次连通。
另一实施例中，每一隔板1212至少设置一个过水口1212a以使得多个子腔室121a′依次连通，也就是说，可以在每一个隔板1212上分别设置过水口1212a，以使得多个子腔室121a′能够依次连通。也就是说，隔板1212的周缘均与箱壳1211的内壁密封地连接在一起，过水口1212a直接设置在隔板1212上。
可以理解的是，当储水腔121a中设置有至少两个隔板1212时，可以是一部分隔板1212上设置有过水口1212a，另一部分隔板1212的一部分边缘与箱壳1211的内壁间隔设置以形成过水口1212a。
一实施例中，请参阅图13，隔板1212的数量至少为两个，相邻两隔板1212对应的过水口1212a错开布置。由于水流是从上层子腔室121a′流向下层子腔室121a′的，因此，将相邻两隔板1212对应的过水口1212a错开布置，既可以尽可能地延长水流的流动路径和延长水流在储水腔121a中的停留时间。
另外，在设置有至少两个隔板1212的水箱121的实施例中，水箱121的入口12a也可以与沿水流流动方向的第一个隔板1212对应的过水口1212a错开布置，和/或，沿水流流动方向的最后一个隔板1212对应的过水口1212a与过流口121b错开布置。由此，也可以延长水流在储水腔121a中的停留时间。
可以理解的是，当水箱121只设置有一个隔板1212，一个隔板1212将储水腔121a分隔为两个子腔室121a′时，也可以是入口12a与隔板1212对应的过水口1212a错开布置，和/或，排水口12b与隔板1212对应的过流口121b错开布置。
一实施例中，请参阅图10，过水口1212a位于对应的隔板1212靠近内筒20转动轴线一侧的边缘处。在内筒20高速转动过程中，水流靠近储水腔121a的外侧，因此水流不易从过水口1212a处向下流动。
一实施例中，箱壳1211面向内筒20一侧的表面与内筒20的内表面贴合，由此，可以减少水箱121所占用的空间。
一实施例中，在内筒20的俯视投影中，箱壳1211沿内筒20径向向内侧的表面形状呈与内筒20同轴的弧形。由此，也可以减少水箱121所占用的空间。
在箱壳1211面向内筒20一侧的表面与内筒20的内表面贴合，且箱壳1211沿内筒20径向向内一侧的表面形状呈与内筒20同轴的弧形的实施例中，可以使得水箱121的结构更加紧凑，进而可以极大地减少水箱121所占用的空间。
一实施例中，多个水箱组件12与内筒20固定连接，比如，可以在水箱121上设置螺柱，螺钉从内筒20的外侧穿过内筒20且拧入水箱121的螺柱内。水箱121也可以焊接在内筒20上，由此，也可以起到防止水箱组件12松动的作用。
一实施例中，请参阅图7至图9，平衡装置10还包括环绕在内筒20顶端的环形导水件11，环形导水件11具有多个相互独立的进水水路11a，每个进水水路11a分别具有盛接注水组件40排出的进水水流的环形进水口11b，每个进水水路11a向对应的一个水箱组件12供水。该实施例中，当内筒20在转动过程中，环形进水口11b能够不间断地盛接进水水流，因此， 衣物处理设备向水箱组件12内的注水过程不会受到内筒20的转动的影响。
需要说明的是，在水箱组件12设置于内筒20和外桶30之间的实施例中，环形导水件11环绕在内筒20的顶端的外表面。在水箱组件12设置于内筒20的实施例中，环形导水件11环绕在内筒20的顶端的内表面。
一实施例中，请参阅图4和图5，注水组件40包括进水阀41和多个注水管42，每个注水管42朝向对应的一个环形进水口11b注水，进水阀41能够选择性地导通或截止每个注水管42内的水路。需要说明的是，注水组件40通过进水阀41与控制主板电连接，控制主板控制进水阀41的得电或失电即可控制注水组件40选择性地向一个或多个环形进水口11b注水。
每个水箱组件12可以只与一条进水水路11a连通，也可以与两条或两条以上的进水水路11a连通，但是，每条进水水路11a只与一个水箱组件12连通，也就是说，每条进水水路11a只能向一个水箱组件12的水箱121供水，不能同时向多个水箱组件12的水箱121供水。
进水阀41的具体类型不限。只要能够控制多个注水管42的水路的通断即可。
需要说明的是，环形进水口11b可以位于环形导水件11的顶侧，也可以位于环形导水件11沿径向向外的周向表面。一些实施例中，所有的环形进水口11b均位于环形导水件11的顶侧，另一些实施例中，所有的环形进水口11b均位于环形导水件11沿径向向外的周向表面，再一些实施例中，部分环形进水口11b位于环形导水件11的顶侧，另一部分环形进水口11b位于环形导水件11沿径向向外的周向表面。
一实施例中，请参阅图14，环形导水件11包括环形壳体111和至少一个隔档板112；环形壳体111具有环形腔室，至少一个隔档板112设置在环形腔室中，以将环形腔室分隔为多个进水水路11a。也就是说，可以通过在环形腔室中设置隔档板112的方式来设置多个进水水路11a，由此，可以便 于生产加工。
一具体地实施例中，请参阅图14，环形壳体111包括第一环形侧板1111、第二环形侧板1112以及底板1113，第一环形侧板1111、第二环形侧板1112以及底板1113围设形成顶侧敞开的环形腔室，第一环形侧板1111和第二环形侧板1112同心设置，第一环形侧板1111位于第二环形侧板1112沿径向的内侧，底板1113连接于第一环形侧板1111的底端和第二环形侧板1112的底端之间。
隔档板112包括相互连接的第一横隔板1121和第一纵隔板1122，第一纵隔板1122竖向设置。第一横隔板1121从第一纵隔板1122的底端朝向第一环形侧板1111方向延伸且与第一环形侧板1111连接，或者，第一横隔板1121从第一纵隔板1122的底端朝向第二环形侧板1112方向延伸且与第二环形侧板1112连接。具体地，在隔挡板112的数量为两个或两个以上的实施例中，多个隔档板112的第一横隔板1121沿衣物处理设备的高度方向层层排布，多个隔档板112的第二横隔板1122沿内筒20的径向方向依次层层排布。
请参阅图14，第一横隔板1121上和底板1113上分别设置有用于将对应的进水水路11a中的水导向对应的水箱121中的出水口11c。也就是说，所有进水水路11a的环形进水口11b均设置在环形导水件11径向的顶侧，每个进水水路11a既有竖向过水空间也横向过水空间，多个进水水路11a的竖向过水空间沿环形导水件11的径向依次排列，多个进水水路11a的横向过水空间沿竖直方向层叠设置，其中，有一个进水水路11a是以底板1113为底壁，其它的进水水路11a是以对应的第一横隔板1121为底壁，以底板1113为底壁的进水水路11a通过设置在底板1113上的出水口11c与对应的水箱组件12的储水腔121a连通，以第一横隔板1121为底壁的进水水路11a通过对应的第一横隔板1121上的出水口11c与对应的水箱组件12的储水腔 121a连通，由此，既便于水流通过，又可以保证多个进水水路11a不会在衣物处理设备中占用太多的空间。
一具体地实施例中，在内筒20的俯视投影中，所有出水口11c位于以内筒20的轴线为圆心的同一个圆上。也就是说，所有的水箱组件12均布置在以内筒20的轴线为圆心的同一个圆的圆周上，如此，能够使得平衡装置10相对内筒20的平衡稳定性更好。
一实施例中，请参阅图15和图16，所有进水水路11a的环形进水口11b均设置在环形导水件11的顶侧，环形盖体32设置有贯穿环形盖体32的开口32a，注水管42的末端从开口32a处伸入环形盖体32的下方且对准对应的环形进水口11b。此种设置方式既便于布置注水组件40，又便于注水管42向对应的环形进水口11b注水。
一具体地实施例中，请参阅图16和图17，注水管42具有进水通道42a，在垂直于水流流动方向的平面投影中，位于进水阀41沿水流流动方向下游的进水通道42a包括主流道42b以及沿主流道42b的周向间隔布置的多个弧形辅流道42c，每个弧形辅流道42c均与主流道42b连通。相关技术中的注水管42的进水通道42a在垂直于水流流动方向的平面投影中的形状为圆形，但是，对于此种注水管42来说，当水流从进水通道42a流出后，会呈锥形的发散状，由此使得水流容易溅入相邻的环形进水口11b中。而本申请实施例中，主流道42b和多个弧形辅流道42c的结构形式，可以起到聚拢水流的作用，以使水流从进水通道42a流出后，会大致呈柱状流向对应的环形进水口11b，而不易溅入相邻的环形进水口11b中。
本申请实施例还提供一种上述任一实施例的衣物处理设备的控制方法，请参阅图18，包括如下步骤。
S1：获取内筒20的负载偏心信息。获取负载偏心信息的方式不限，可以采用现有技术中任意一种检测负载偏心的手段。例如获取内筒20在竖直 方向和水平方向的位移量，根据位移量计算出内筒20在竖直方向上的受力变化，以此来确定内筒20内的负载是否发生偏心。
S2：根据负载偏心信息确定待注水的水箱组件12。例如，当负载朝向一侧偏心时，则位于偏心侧相反一侧的水箱组件12为待注水水箱组件12。
S3：控制注水组件40向待注水的水箱组件12注水。
本申请实施例的控制方法为主动平衡控制方法，能够根据负载偏心信息主动控制注水组件40向待注水的水箱组件12注水，无论内筒20的转速高低，只要确定内筒20偏心且需要平衡时，就可以主动注水以抵抗内筒20偏心。
需要说明的是，本申请实施例中的负载指的是放入内筒20的洗涤衣物的集合。
一实施例中，负载偏心信息包括负载偏心质量和偏心位置。需要说明的是，负载偏心质量越大，平衡内筒20偏心所需的水量越大。偏心位置离内筒20转动轴线越远，平衡内筒20偏心所需的数量越大。
一些实施例中，当偏心位置与内筒20转动轴线之间的距离超出一定的数值时，控制主板才会控制确定需要对内筒20进行平衡。
一实施例中，在的控制注水组件40向待注水的水箱组件12注水的步骤之前，控制方法还包括：根据负载偏心信息确定平衡所需的注水量。如上，注水量与负载偏心质量、偏心位置均有关系，因此，在注水之前，需要根据平衡所需的注水量，以控制注水组件40向待注水的水箱组件12注入不少于所需的注水量。
一实施例中，的控制注水组件40向待注水的水箱组件12注水的步骤具体包括：控制注水组件40向待注水的水箱组件12注水预设时间后关闭。在预设时间内，注水组件40注入水箱组件12中的实际注水量不低于计算的所需注水量。
本申请提供的各个实施例/实施方式在不产生矛盾的情况下可以相互组合。
以上所述仅为本申请的较佳实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
