Description

滚筒洗衣机及其喷淋系统 技术领域
本发明属于家用电器领域，具体提供一种滚筒洗衣机及其喷淋系统。
背景技术
现有滚筒洗衣机发源于欧洲，其由外至内主要包括箱体、外筒和内筒。滚筒洗衣机的工作方式与棒锤击打衣物原理类似。工作时，内筒在驱动电机的带动下转动。随着内筒的转动，衣物在滚筒中不断地被提升摔下，再提升再摔下，做重复运动。在洗衣粉和水的共同作用下，衣物被洗涤干净。
为了提高水流冲洗和漂洗衣物的效果，有的滚筒洗衣机还设置有循环喷淋装置。如公开号为CN102482834B的专利文献中公开的滚筒式洗衣机，其内设置有循环路径，该循环路径的一端通向水槽(外筒)的底端，该循环路径的另一端通向设置在水槽开口边缘的多个喷出口，该循环路径的中部设置有循环泵。循环泵工作时能够通过循环路径将洗涤水从水槽的底端供给所述多个喷出口，多个喷出口同时地将洗涤水喷进滚筒(内筒)中，对衣物进行循环冲洗。
但是，公开号为CN102482834B的专利文献中公开的滚筒式洗衣机的喷淋模式比较单一，对衣物的喷淋效果较差。
相应地，本领域需要一种新的滚筒洗衣机及其喷淋系统来解决上述问题。

具体实施方式
本领域技术人员应当理解的是，本节实施方式仅仅用于解释本发明的技术原理，并非用于限制本发明的保护范围。例如，虽然附图中的各部件之间是按一定比例关系绘制的，但是这种比例关系并非一成不变，本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合，调整后的技术方案仍将落入本发明的保护范围。
还需要说明的是，在本发明的描述中，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，可 以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
如图1和图2所示，本发明的滚筒洗衣机主要包括箱体1、外筒2、内筒3、门体4、密封窗垫5、排水泵6和排水管7。其中，外筒2固定地设置在箱体1内，内筒3可转动地设置在外筒2中，密封窗垫5设置在箱体1和外筒2之间。排水泵6和排水管7都设置在箱体1内，并且排水泵6的进水口通向外筒2的内底部，排水泵6的出水口与排水管7的一端连接，排水管7的另一端通向外界。排水泵6能够将外筒2内的洗涤水通过排水管7排出。
此外，本领域技术人员能够理解的是，在排水管7的每个部位都低于外筒2的内底端时，本领域技术人员还可以根据需要，省去排水泵6，将排水泵6替换成截止阀。当滚筒洗衣机需要排水时，打开该截止阀，使外筒2中的洗涤水在自身重力的作用下从排水管7自动排出。
继续参阅图1和图2，箱体1的前端(图2中箱体1的右侧)设置有箱体口(图中未标示)，外筒2的前端(图2中外筒2的右侧)设置有外筒口(图中未标示)，内筒3的前端(图2中内筒3的右侧)设置有内筒口(图中未标示)。密封窗垫5的一端与箱体口的边缘密封连接，密封窗垫5的另一端与外筒口的边缘密封连接。门体4枢转地设置在箱体1上，并且门体4关闭时能够封闭所述箱体口，防止外筒2中的洗涤水从箱体口溢出。
继续参阅图1和图2，本发明的滚筒洗衣机还包括喷淋系统，该喷淋系统主要包括循环泵8、出水管9、控制阀10、八根分支管11和八个喷嘴12。其中，循环泵8优选地设置在箱体1内且与箱体1固定连接。或者本领域技术人员也可以根据需要，使循环泵8与外筒1固定连接。循环泵8的进水口通向外筒2的内部，优选地，循环泵8的进水口通过进水管(图中未标示)与外筒2的底端连接。或者本领域技术人员也可以根据需要，在保证该进水管位于外筒2内液面以下的情况下，可以将进水管连接到外筒2的任意位置。循环泵8的出水口通过出水管9和控制阀10的进水阀口1011连通。或者，本领域技术人员也可以根据需要，省去出水管9，使循环泵8的出水口与控制阀10的进水阀口1011直接连通。
如图2至图4所示，八个喷嘴12绕外筒2的周向等间距地设置在密封窗垫5上。或者，本领技术人员也可以根据需要，将多个喷嘴12非等间距地设置在密封窗垫5上。其中，所有的喷嘴12都穿过密封窗垫5，并且都与密封窗垫5密封连接，防止外筒2中的洗涤水泄漏。
此外，本领域技术人员还可以根据需要，将八个喷嘴12设置在外筒2前端附近的任意位置，例如，将八个喷嘴12设置在门体4的内侧，将八个喷嘴12设置在外筒口的边缘处。进一步，本领域技术人员还可以根据需要，将八个喷嘴12设置成其他任意可行的数量，例如五个、六个、九个等。
如图1至图3所示，每一个喷嘴12的出水口都指向内筒3口，以便从喷嘴12喷出的水都能够落入内筒3中，对衣物进行喷淋。或者，本领域技术人员还可以根据需要，在多个喷嘴12能够将洗涤水喷向内筒3中的前提下，使喷嘴12指向门体4，然后借助门体4的反射作用，使洗涤水喷进入内筒3中。
继续参阅图1和图2，控制阀10优选地设置在箱体1内且与箱体1(例如箱体1的内侧壁)固定连接。本领域技术人员还可以根据需要，使控制阀10采用任意可行的连接方式与箱体1固定连接。例如，在控制阀10上设置卡接结构或固定结构，借助该卡接结构或固定结构将控制阀10固定到箱体1上。或者本领域技术人员也可以根据需要，使控制阀10与外筒1固定连接。
如图4、图5a至图5c所示，在本发明的第一实施方案中，控制阀10是四通阀，其包括阀体101和枢转地设置在阀体101中的阀芯102。其中，阀体101上设置有进水阀口1011、第一出水阀口1012、第二出水阀口1013和第三出水阀口1014。其中，进水阀口1011与出水管9连通，第一出水阀口1012、第二出水阀口1013和第三出水阀口1014分别连接一组喷嘴12。此外，本领域技术人员还可以根据需要，将控制阀10设置成其他的多通阀，例如，三通阀、五通阀、六通阀等。
如图4所示，八个喷嘴12被分成下、中、上三组。其中，下组包括三个喷嘴12，记做第一组喷嘴；中组包括两个喷嘴12，记做第二组喷嘴；上组包括三个喷嘴12，记做第三组喷嘴。第一组喷嘴中的每一个喷嘴12都通过分支管11分别与第一出水阀口1012连通。第二组喷 嘴中的每一个喷嘴12都通过分支管11分别与第二出水阀口1013连通，第三组喷嘴中的每一个喷嘴12都通过分支管11分别与第三出水阀口1014连通。此外，本领域技术人员也可以根据需要，将三组喷嘴和三个出水阀口的对应关系适当调整，例如使第一组喷嘴与第三出水阀口1014对应，使第二组喷嘴与第一出水阀口1012对应，使第三组喷嘴与第二出水阀口1013对应。
如图5a至图5c所示，阀芯102与第一出水阀口1012、第二出水阀口1013和第三出水阀口1014对准的截面呈扇形。换句话说，第一出水阀口1012、第二出水阀口1013和第三出水阀口1014能够同时相交于同一平面，阀芯102被该平面剖切之后呈扇形。其中，该扇形的枢转轴线与所述扇形所属圆的圆心重合。
如图5a和图6a所示，当阀芯102转动到图5a所示的第一切换位时，进水阀口1011与第一出水阀口1012连通，第一组喷嘴将循环泵8泵送的洗涤水喷射进内筒3中。
如图5b和图6b所示，当阀芯102转动到图5b所示的第二切换位时，进水阀口1011与第一出水阀口1012和第二出水阀口1013连通，第一组喷嘴和第二组喷嘴同时将循环泵8泵送的洗涤水喷射进内筒3中。
如图5c和图6c所示，当阀芯102转动到图5c所示的第三切换位时，进水阀口1011与第一出水阀口1012、第二出水阀口1013和第三出水阀口1014都连通，第一组喷嘴、第二组喷嘴和第三组喷嘴同时将循环泵8泵送的洗涤水喷射进内筒3中。
此外，当阀芯102转动到堵住进水阀口1011时，记做第四切换位，进水阀口1011与第一出水阀口1012、第二出水阀口1013和第三出水阀口1014都不连通。
如图7a至图8d所示，在本发明的第二实施方案中，与第一实施方案不同的是，阀芯102与第一出水阀口1012、第二出水阀口1013和第三出水阀口1014对准的截面呈Y形，并且该Y形的一个分支上还设置有通孔1021。此外，本领域技术人员也可以根据需要，将阀芯102的Y形的截面设置成T形或△形。
如图7a和图8a所示，当阀芯102转动到图7a所示的第一切换位时，进水阀口1011通过通孔1021与第一出水阀口1012连通，第一组喷嘴将循环泵8泵送的洗涤水喷射进内筒3中。
如图7b和图8b所示，当阀芯102转动到图7b所示的第二切换位时，进水阀口1011通过通孔1021与第二出水阀口1013连通，第二组喷嘴将循环泵8泵送的洗涤水喷射进内筒3中。
如图7c和图8c所示，当阀芯102转动到图7c所示的第三切换位时，进水阀口1011通过通孔1021与第三出水阀口1014都连通，第三组喷嘴将循环泵8泵送的洗涤水喷射进内筒3中。
如图7d和图8d所示，当阀芯102转动到图7d所示的第四切换位时，进水阀口1011通过阀芯102上Y形结构的缺口(图中未标示)与第一出水阀口1012连通，通过通孔1021与第二出水阀口1013和第三出水阀口1014都连通，第一组喷嘴、第二组喷嘴和第三组喷嘴同时将循环泵8泵送的洗涤水喷射进内筒3中。
此外，当阀芯102转动到堵住进水阀口1011时，记做第五切换位，进水阀口1011与第一出水阀口1012、第二出水阀口1013和第三出水阀口1014都不连通。
需要说明的是，无论在本发明的第一实施例还是第二实施例中，控制阀10都是电磁控制阀，以便该电磁控制阀能够被设置在箱体1上的操作按钮操作，并因此改变其切换位。
本领域技术人员能够理解的是，第一实施例和第二实施例中的电磁阀10既可以被用户手动操作，改变切换位；也可以被滚筒洗衣机上的控制器按一定的指令操作，按一定规律地改变切换位。
进一步，虽然图中并未示出，但是在本发明的第三实施方案中，电磁阀10还可以被多个电磁截止阀替代。示例性地，被三个截止阀替代，并使三个截止阀分别连接并控制第一组喷嘴、第二组喷嘴和第三组喷嘴的通断。以便三组喷嘴之间既可以彼此独立地向内筒3中喷射洗涤水，也可以彼此组合地向内筒3中喷射洗涤水。此外，本领域技术人员还可以根据需要，将电磁截止阀的数量进行适当调整，以及将每个电磁截止阀控制的喷嘴12数量进行调整。例如，设置八个电磁截止阀，使每一个电磁截止阀分别控制一个喷嘴12。
本领域技术人员能够理解的是，在本发明的上述三个实施例中，通过控制阀10或截止阀能够选择性地控制第一组喷嘴、第二组喷嘴和第三组喷嘴将循环泵8泵送的洗涤水喷射进内筒3中，优化了滚筒洗衣机的喷淋效果，使滚筒洗衣机能够选择性地从上方、侧方或下方对内筒3中的衣物进行喷淋。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
