Description

波轮洗衣机及其喷淋***和外桶盖 技术领域
本发明属于喷淋设备领域，具体提供一种波轮洗衣机及其喷淋***和外桶盖。
背景技术
波轮洗衣机主要包括箱体、外桶、内桶和波轮。其中，外桶固定地设置在箱体中，内桶可转动的设置在外桶中，波轮可转动的设置在外桶底部。在波轮洗衣机执行洗涤、漂洗作业时，波轮驱动外桶中的洗涤水和衣物转动，以达到清洗衣物的目的。在波轮洗衣机执行甩干作业时，内桶带动其内的衣物高速转动，使衣物上的水分在离心力的作用脱离衣物。
波轮洗衣机在使用的过程中经常会存在下列问题：其一，洗衣粉、洗衣液沉积在外桶的底部，不容易被洗涤水溶解；其二，洗涤的衣物较多时，容易出现部分衣物未被洗涤水浸润的情况；其三，羽绒等衣物在洗涤时经常漂在洗涤水液面以上，洗涤效果较差。
为了解决上述问题，现有的波轮洗衣机通常在外桶盖上设置喷淋装置。例如公告号为CN204282066U的专利文献中公开了一种波轮洗衣机，该波轮洗衣机的外桶盖上设置有多个喷嘴。在波轮洗衣机工作时，循环水泵能够将外桶中的洗涤水泵送给所述多个喷嘴，使多个喷嘴将洗涤水喷淋到内桶中的衣物上。但是该波轮洗衣机的喷淋效果较差，不能对浮出洗涤水液面的衣物进行全方位的喷淋。
相应地，本领域需要一种新的波轮洗衣机及其喷淋***和外桶盖来解决上述问题。

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。
需要说明的是，在本发明的描述中，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示方向或位置关系的术语是基于附图所示的方向或位置关系，这仅仅是为了便于描述，而不是指示或暗示所述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。此外，术语“第一”、“第二”、“第三”仅用于描述目的，而不能理解为指示或暗示相对重要性。
此外，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。
技术方案1：
如图1和图2所示，本发明的波轮洗衣机主要包括箱体1、外桶2、内桶3、波轮4、驱动电机5、排水阀6和排水管7。其中，外桶2固定地设置在箱体1的内部，内桶3可转动的设置在外桶2中，波轮4可转动的设置在内桶3的底部。驱动电机5固定地安装到箱体1或外桶2上，驱动电机5通过转轴与内桶3和波轮4分别驱动连接。驱动电机5能够选择性地驱动内通3和波轮4转动。由于驱动电机5选择性地驱动内通3和波轮4的技术手段是本领域技术人员所熟知的技术手段，所以此处不再做过多说明。进一步，排水阀6的进水阀口通过水管与外桶2的内腔连通，排水阀6的出水阀口通过排水管7通向箱体1外。当外桶2内的洗涤水需要排出时，排水阀6被打开，洗涤水从排水管7排向外界。
优选地，外桶2上与排水阀6连通的排水口位于外桶2的底部，以便外桶2中的洗涤水能够通过该排水口拍净。进一步优选地，排水阀6被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将排水阀6安装到外桶2的外壁上。此外，本领域技术人员还可以根据需要，省去排水阀6和外桶2之间的水管，使排水阀6直接安装到外桶2上，并与外桶2的内腔连通。
如图2所示，本发明的箱体1的顶部安装有盘座11，盘座11枢转地连接有门盖12。外桶2的顶部设置有外桶盖21，外桶盖21用于遮挡内桶3的上边缘，防止衣物进入外桶2和内桶3之间的夹层中。
如图3至图6所示，外桶盖21主要包括盖体211、环形腔212和进水口213，其中，环形腔212和进水口213都设置在盖体211上。本领域技术人员能够理解的是，盖体211既可以是一体制成的结构，也可以是由多个分体结构安装而成。示例性地，盖体211包括上盖体和下 盖体，上盖体和下盖体中的至少一个上设置有环形槽。当上盖体和下盖体安装到一起时，上盖体和下盖体将环形槽封闭成所述环形腔212。
如图2、图5和图6所示，本发明的波轮洗衣机还包括喷淋***，该喷淋***包括循环泵8、循环水管9、环形腔212、进水口213和多个喷嘴10。
如图2所示，循环泵8的进水泵口通过水管与外桶2的内腔连通，循环泵8的出水泵口通过循环水管9与外桶盖21上的进水口213连通。优选地，外桶2上与循环泵8连通的出水口位于外桶2的底部。进一步优选地，循环泵8被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将循环泵8安装到外桶2的外壁上。此外，本领域技术人员还可以根据需要，省去循环泵8和外桶2之间的水管，使循环泵8直接安装到外桶2上，并与外桶2的内腔连通。
如图5和6所示，多个喷嘴10沿外桶盖21的周向等间距地固定地连接到或者一体成型到盖体211上，并且每一个喷嘴10都分别与环形腔212连通。进一步，每一个喷嘴10的喷射口都指向内桶3。此外，本领域技术人员也可以根据需要，使多个喷嘴10非等间距地设置在盖体211上。
如图6和图7所示，在本发明的第一实施例中，每一个喷嘴10均相同，并且每一个喷嘴10的喷射口的延伸方向与水平方向(或竖直方向)的夹角都不相同。示例性地，如图6中左侧的喷嘴10，其喷嘴本体101(如图8所示)的轴线与竖直方向的夹角为90°；如图6中右侧的喷嘴10，其喷嘴本体101(如图8所示)的轴线与竖直方向的夹角为98°；如图7中右侧的喷嘴10，其喷嘴本体101(如图8所示)的轴线与竖直方向的夹角为76°。
本领域技术人员能够理解的是，基于每一个喷嘴10与水平方向(或竖直方向)的夹角不同，洗涤水被喷嘴10喷出之后会沿内桶3的圆周方向形成高度差(如图6和图7所示)，被每一个喷嘴10喷出的洗涤水经过内桶3的轴线时彼此之间的高度也不相同。因此，被喷淋的洗涤水能够对内桶3中漂浮在洗涤水液面以上的衣物进行立体地、全方位地喷淋，尤其是衣物随着波轮4的转动而转动时。
此外，本领域技术人员也可以根据需要，将多个喷嘴10分成多个组，使每一组包括至少两个喷嘴10。每一组喷嘴10中的所有喷嘴10与水平方向(或竖直方向)的夹角均相同。本领域技术人员能够理解的是，同一组中的多个喷嘴10既可以相邻设置，也可以间隔设置，并且每一组中喷嘴10的数量既可以相同，也可以不同。
继续参阅图5和图6，外桶盖21的盖体211的内侧还设置有环形的遮挡结构2111，该遮挡结构2111用于遮挡喷嘴10，防止喷嘴10被用户观察到，以便优选外桶盖21的外观。
虽然图中并未示出，但是在本发明另一个可行的实施例中，本领域技术人员可以根据需要，将多个喷嘴10直接地固定到外桶2的顶部，然后使循环水管9直接地或者借助其它水管与每一个喷嘴10连通。
如图2所示，循环泵8工作时能够将外桶2中的洗涤水吸出，并通过循环水管9泵送给外桶盖21上的环形腔212，进而使喷嘴10将洗涤水喷向内桶3中，对内桶3中的衣物进行喷淋。
此外，虽然图中并未示出，但是在本发明喷淋***另一个可行的实施例中，本领域技术人员也可以根据需要，使外桶盖21上的进水口213通过水管与波轮洗衣机的进水阀连通。当进水阀的进水阀口与水龙头接通时，自来水能够沿着进水阀、水管和进水口213的路径提供给环形腔212，进而使喷嘴10将自来水喷射到内桶3中的衣物上，湿润衣物。
进一步，本领域技术人员也可以根据需要，使本发明的喷淋***同时具有上述的循环泵8、循环水管9、进水阀以及连通进水阀和进水口213的水管，并且在进水阀和进水口213串联一个截止阀。此时，循环泵8和进水阀可以分别或共同作为供水设备。当需要自来水喷淋衣物时，进水阀和截止阀被打开。当需要外桶2中的洗涤水喷淋衣物时，循环泵8工作。
下面参照图8至图13来对本发明的喷嘴10进行详细说明。
如图8至图11所示，喷嘴10包括喷嘴本体101和挡水结构102。其中，喷嘴本体101和挡水结构102可以采用任意可行的连接方式固定到一起，例如焊接、熔接、粘接等。或者，本领域技术人员也可以根据需要，使喷嘴本体101和挡水结构102一体制成。
如图9和图11所示，喷嘴本体101内设置有喷射通道1011。当喷嘴10安装到外桶盖21上时，图10中喷射通道1011的下端与环形腔212连通。环形腔212中的洗涤水流经喷射通道1011之后从图10中喷射通道1011的上端喷向挡水结构102，挡水结构102将洗涤水打散并反射进内桶3中。本领域技术人员能够理解的是，喷嘴本体101可以是任意可行的形状，例如，圆形管柱结构、方形管柱结构、锥形管柱结构等。
如图8至图11所示，挡水结构102沿喷嘴本体101的轴向遮挡喷射通道1011。挡水结构102面向喷嘴本体101的一侧设置有凹部1021。优选地，该凹部1021是具有弧形表面的凹部，即凹部1021的内表面是弧形面。进一步优选地，挡水结构102整体上为勺形结构。此外本领域技术人员也可以根据需要，将挡水结构102设置成其它任意可行的结构，例如，具有凹面的板状结构或具有凹面的块状结构。
如图10所示，洗涤水从喷射通道1011喷出之后会呈束状地喷向凹部1021内。落入凹部1021内的洗涤水会从着落点沿着凹部1021的弧面延展开来，最后从凹部1021的边缘流出形成扇形的瀑布状水流(如图12和图13所示)落入内桶3中。
本领域技术人员能够理解的是，通过改变凹部1021中弧形凹面的角度，能够调整洗涤水喷出的形状。如图12所示凹部1021的凹面是均匀的球面；如图13所示凹部1021的凹面是左右对称非均匀的弧面，并且该凹面向对称轴收紧，以便使洗涤水比较集中，喷的尽量远些。
本领域技术人员还能够理解的是，在能够将喷射通道1011喷出的洗涤水打散的前提下，凹部1021除了是弧形的外，还可以是任意可行的形状，例如U形凹部或扩口凹部。
如图14所示，在本发明的第二实施例中，每一个喷嘴10的喷嘴本体101都与水平方向平行，并且每一个喷嘴10的喷射口的延伸方向与水平方向(或竖直方向)的夹角都不相同。示例性地，图6中左侧的喷嘴10，其喷射口的延伸方向(即洗涤水喷出的方向)与竖直方向的夹角为34°；如图6中右侧的喷嘴10，其喷射口的延伸方向(即洗涤水喷出的方向)与竖直方向的夹角为57°。
在第二实施例中，每一喷嘴10的挡水结构102与水平方向(或竖直方向)的夹角都不相同，以便在保证每一个喷嘴10的喷嘴本体101都水平设置的前提下，使每一个喷嘴10的喷射口的延伸方向与水平方向(或竖直方向)的夹角都不相同。示例性地，图15a中所示的喷嘴10的挡水结构102与图15a中水平方向的夹角为a，图15b中所示的喷嘴10的挡水结构102与图15b中水平方向的夹角为b。其中a＜b。
此外，本领域技术人员也可以根据需要，将多个喷嘴10分成多个组，使每一组包括至少两个喷嘴10。同一组中的每一个喷嘴10的结构均相同。本领域技术人员能够理解的是，同一组中的多个喷嘴10既可以相邻设置，也可以间隔设置，并且每一组中喷嘴10的数量既可以相同，也可以不同。
综上所述，在本发明的优选技术方案中，通过在挡水结构102面向喷嘴本体101的一侧设置凹部1021，使得喷射通道1011喷出的束状洗涤水能够被凹部1021均匀地打散开并流进内桶3中，对内桶中3的衣物进行均匀地喷淋。因此，本发明的喷嘴10能够提高波轮洗衣机对内桶3中衣物的喷淋效果，进而优化波轮洗衣机对衣物的洗涤效果。

如图16和图17所示，本发明的波轮洗衣机主要包括箱体1、外桶2、内桶3、波轮4、驱动电机5、排水阀6和排水管7。其中，外桶2固定地设置在箱体1的内部，内桶3可转动的设置在外桶2中，波轮4可转动的设置在内桶3的底部。驱动电机5固定地安装到箱体1或外桶2上，驱动电机5通过转轴与内桶3和波轮4分别驱动连接。驱动电机5能够选择性地驱动内通3和波轮4转动。由于驱动电机5选择性地驱动内通3和波轮4的技术手段是本领域技术人员所熟知的技术手段，所以此处不再做过多说明。进一步，排水阀6的进水阀口通过水管与外桶2的内腔连通，排水阀6的出水阀口通过排水管7通向箱体1外。当外桶2内的洗涤水需要排出时，排水阀6被打开，洗涤水从排水管7排向外界。
优选地，外桶2上与排水阀6连通的排水口位于外桶2的底部，以便外桶2中的洗涤水能够通过该排水口拍净。进一步优选地，排水阀6被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将排水阀6安装到外桶2的外壁上。此外，本领域技术人员还可以根据 需要，省去排水阀6和外桶2之间的水管，使排水阀6直接安装到外桶2上，并与外桶2的内腔连通。
如图17所示，本发明的箱体1的顶部安装有盘座11，盘座11枢转地连接有门盖12。外桶2的顶部设置有外桶盖21，外桶盖21用于遮挡内桶3的上边缘，防止衣物进入外桶2和内桶3之间的夹层中。
如图18至图21所示，外桶盖21主要包括盖体211、环形腔212和进水口213，其中，环形腔212和进水口213都设置在盖体211上。本领域技术人员能够理解的是，盖体211既可以是一体制成的结构，也可以是由多个分体结构安装而成。示例性地，盖体211包括上盖体和下盖体，上盖体和下盖体中的至少一个上设置有环形槽。当上盖体和下盖体安装到一起时，上盖体和下盖体将环形槽封闭成所述环形腔212。
如图17、图20和图21所示，本发明的波轮洗衣机还包括喷淋***，该喷淋***包括循环泵8、循环水管9、环形腔212、进水口213和多个喷嘴10。
如图17所示，循环泵8的进水泵口通过水管与外桶2的内腔连通，循环泵8的出水泵口通过循环水管9与外桶盖21上的进水口213连通。优选地，外桶2上与循环泵8连通的出水口位于外桶2的底部。进一步优选地，循环泵8被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将循环泵8安装到外桶2的外壁上。此外，本领域技术人员还可以根据需要，省去循环泵8和外桶2之间的水管，使循环泵8直接安装到外桶2上，并与外桶2的内腔连通。
如图20和21所示，多个喷嘴10沿外桶盖21的周向等间距地固定地连接到或者一体成型到盖体211上，并且每一个喷嘴10都分别与环形腔212连通。进一步，每一个喷嘴10的喷射口都指向内桶3。此外，本领域技术人员也可以根据需要，使多个喷嘴10非等间距地设置在盖体211上。
如图21和图22所示，在本发明的第一实施例中，每一个喷嘴10均相同，并且每一个喷嘴10的喷射口的延伸方向与水平方向(或竖直方向)的夹角都不相同。示例性地，如图21中左侧的喷嘴10，其喷嘴本体101(如图23所示)的轴线与竖直方向的夹角为90°；如图21中右侧的喷嘴10，其喷嘴本体101(如图23所示)的轴线与竖直方向的 夹角为98°；如图22中右侧的喷嘴10，其喷嘴本体101(如图23所示)的轴线与竖直方向的夹角为76°。
本领域技术人员能够理解的是，基于每一个喷嘴10与水平方向(或竖直方向)的夹角不同，洗涤水被喷嘴10喷出之后会沿内桶3的圆周方向形成高度差(如图21和图22所示)，被每一个喷嘴10喷出的洗涤水经过内桶3的轴线时彼此之间的高度也不相同。因此，被喷淋的洗涤水能够对内桶3中漂浮在洗涤水液面以上的衣物进行立体地、全方位地喷淋，尤其是衣物随着波轮4的转动而转动时。
此外，本领域技术人员也可以根据需要，将多个喷嘴10分成多个组，使每一组包括至少两个喷嘴10。每一组喷嘴10中的所有喷嘴10与水平方向(或竖直方向)的夹角均相同。本领域技术人员能够理解的是，同一组中的多个喷嘴10既可以相邻设置，也可以间隔设置，并且每一组中喷嘴10的数量既可以相同，也可以不同。
继续参阅图20和图21，外桶盖21的盖体211的内侧还设置有环形的遮挡结构2111，该遮挡结构2111用于遮挡喷嘴10，防止喷嘴10被用户观察到，以便优选外桶盖21的外观。
虽然图中并未示出，但是在本发明另一个可行的实施例中，本领域技术人员可以根据需要，将多个喷嘴10直接地固定到外桶2的顶部，然后使循环水管9直接地或者借助其它水管与每一个喷嘴10连通。
如图17所示，循环泵8工作时能够将外桶2中的洗涤水吸出，并通过循环水管9泵送给外桶盖21上的环形腔212，进而使喷嘴10将洗涤水喷向内桶3中，对内桶3中的衣物进行喷淋。
此外，虽然图中并未示出，但是在本发明喷淋***另一个可行的实施例中，本领域技术人员也可以根据需要，使外桶盖21上的进水口213通过水管与波轮洗衣机的进水阀连通。当进水阀的进水阀口与水龙头接通时，自来水能够沿着进水阀、水管和进水口213的路径提供给环形腔212，进而使喷嘴10将自来水喷射到内桶3中的衣物上，湿润衣物。
进一步，本领域技术人员也可以根据需要，使本发明的喷淋***同时具有上述的循环泵8、循环水管9、进水阀以及连通进水阀和进水口213的水管，并且在进水阀和进水口213串联一个截止阀。此时， 循环泵8和进水阀可以分别或共同作为供水设备。当需要自来水喷淋衣物时，进水阀和截止阀被打开。当需要外桶2中的洗涤水喷淋衣物时，循环泵8工作。
下面参照图23至图28来对本发明的喷嘴10进行详细说明。
如图23至图26所示，喷嘴10包括喷嘴本体101和挡水结构102。其中，喷嘴本体101和挡水结构102可以采用任意可行的连接方式固定到一起，例如焊接、熔接、粘接等。或者，本领域技术人员也可以根据需要，使喷嘴本体101和挡水结构102一体制成。
如图24和图26所示，喷嘴本体101内设置有喷射通道1011。当喷嘴10安装到外桶盖21上时，图25中喷射通道1011的下端与环形腔212连通。环形腔212中的洗涤水流经喷射通道1011之后从图25中喷射通道1011的上端喷向挡水结构102，挡水结构102将洗涤水打散并反射进内桶3中。本领域技术人员能够理解的是，喷嘴本体101可以是任意可行的形状，例如，圆形管柱结构、方形管柱结构、锥形管柱结构等。
如图23至图26所示，挡水结构102沿喷嘴本体101的轴向遮挡喷射通道1011。挡水结构102面向喷嘴本体101的一侧设置有凹部1021。优选地，该凹部1021是具有弧形表面的凹部，即凹部1021的内表面是弧形面。进一步优选地，挡水结构102整体上为勺形结构。此外本领域技术人员也可以根据需要，将挡水结构102设置成其它任意可行的结构，例如，具有凹面的板状结构或具有凹面的块状结构。
如图25所示，洗涤水从喷射通道1011喷出之后会呈束状地喷向凹部1021内。落入凹部1021内的洗涤水会从着落点沿着凹部1021的弧面延展开来，最后从凹部1021的边缘流出形成扇形的瀑布状水流(如图27和图28所示)落入内桶3中。
本领域技术人员能够理解的是，通过改变凹部1021中弧形凹面的角度，能够调整洗涤水喷出的形状。如图27所示凹部1021的凹面是均匀的球面；如图28所示凹部1021的凹面是左右对称非均匀的弧面，并且该凹面向对称轴收紧，以便使洗涤水比较集中，喷的尽量远些。
本领域技术人员还能够理解的是，在能够将喷射通道1011喷出的洗涤水打散的前提下，凹部1021除了是弧形的外，还可以是任意可行的形状，例如U形凹部或扩口凹部。
如图29所示，在本发明的第二实施例中，每一个喷嘴10的喷嘴本体101都与水平方向平行，并且每一个喷嘴10的喷射口的延伸方向与水平方向(或竖直方向)的夹角都不相同。示例性地，图21中左侧的喷嘴10，其喷射口的延伸方向(即洗涤水喷出的方向)与竖直方向的夹角为34°；如图21中右侧的喷嘴10，其喷射口的延伸方向(即洗涤水喷出的方向)与竖直方向的夹角为57°。
在第二实施例中，每一喷嘴10的挡水结构102与水平方向(或竖直方向)的夹角都不相同，以便在保证每一个喷嘴10的喷嘴本体101都水平设置的前提下，使每一个喷嘴10的喷射口的延伸方向与水平方向(或竖直方向)的夹角都不相同。示例性地，图30a中所示的喷嘴10的挡水结构102与图30a中水平方向的夹角为a，图30b中所示的喷嘴10的挡水结构102与图30b中水平方向的夹角为b。其中a＜b。
此外，本领域技术人员也可以根据需要，将多个喷嘴10分成多个组，使每一组包括至少两个喷嘴10。同一组中的每一个喷嘴10的结构均相同。本领域技术人员能够理解的是，同一组中的多个喷嘴10既可以相邻设置，也可以间隔设置，并且每一组中喷嘴10的数量既可以相同，也可以不同。
综上所述，在本发明的优选技术方案中，通过在挡水结构102面向喷嘴本体101的一侧设置凹部1021，使得喷射通道1011喷出的束状洗涤水能够被凹部1021均匀地打散开并流进内桶3中，对内桶中3的衣物进行均匀地喷淋。因此，本发明的喷嘴10能够提高波轮洗衣机对内桶3中衣物的喷淋效果，进而优化波轮洗衣机对衣物的洗涤效果。
技术方案3
如图31和图32所示，本发明的波轮洗衣机主要包括箱体1、外桶2、内桶3、波轮4、驱动电机5、排水阀6和排水管7。其中，外桶2固定地设置在箱体1的内部，内桶3可转动地设置在外桶2中，波轮4可转动地设置在内桶3的底部。驱动电机5固定地安装到箱体1或外桶2上，驱动电机5通过转轴与内桶3和波轮4分别驱动连接。驱动电机5 能够选择性地驱动内通3和波轮4转动。由于驱动电机5选择性地驱动内通3和波轮4的技术手段是本领域技术人员所熟知的技术手段，所以此处不再做过多说明。进一步，排水阀6的进水阀口通过水管与外桶2的内腔连通，排水阀6的出水阀口通过排水管7通向箱体1外。当外桶2内的洗涤水需要排出时，排水阀6被打开，洗涤水从排水管7排向外界。
优选地，外桶2上与排水阀6连通的排水口位于外桶2的底部，以便外桶2中的洗涤水能够通过该排水口拍净。进一步优选地，排水阀6被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将排水阀6安装到外桶2的外壁上。此外，本领域技术人员还可以根据需要，省去排水阀6和外桶2之间的水管，使排水阀6直接安装到外桶2上，并与外桶2的内腔连通。
如图32所示，本发明的箱体1的顶部安装有盘座11，盘座11枢转地连接有门盖12。外桶2的顶部设置有外桶盖21，外桶盖21用于遮挡内桶3的上边缘，防止衣物进入外桶2和内桶3之间的夹层中。
如图33至图35和图37所示，外桶盖21主要包括盖体211、环形腔212和进水口213，其中，环形腔212和进水口213都设置在盖体211上。本领域技术人员能够理解的是，盖体211既可以是一体制成的结构，也可以是由多个分体结构安装而成。示例性地，盖体211包括上盖体和下盖体，上盖体和下盖体中的至少一个上设置有环形槽。当上盖体和下盖体安装到一起时，上盖体和下盖体将环形槽封闭成所述环形腔212。
如图32、图34和图37所示，本发明的波轮洗衣机还包括喷淋***，该喷淋***包括循环泵8、循环水管9、环形腔212、进水口213、多个喷嘴10a和多个挡水结构10b。
如图32所示，循环泵8的进水泵口通过水管与外桶2的内腔连通，循环泵8的出水泵口通过循环水管9与外桶盖21上的进水口213连通。优选地，外桶2上与循环泵8连通的出水口位于外桶2的底部。进一步优选地，循环泵8被安装到箱体1的内壁上，或者本领域技术人员也可以根据需要，将循环泵8安装到外桶2的外壁上。此外，本领域技术人员还可以根据需要，省去循环泵8和外桶2之间的水管，使循环泵8直接安装到外桶2上，并与外桶2的内腔连通。
如图36至图38所示，在本发明的第一实施例中，每一个喷嘴10a分别对应一个挡水结构10b，并且每一个喷嘴10a和与其对应的挡水结构10b固定连接或一体制成。本领域技术人员能够理解的是，该固定连接方式可以是任意可行的方式，例如焊接、熔接、粘接等。进一步，喷嘴10a和挡水结构10b之间形成有喷射口(图中未标示)，每一个喷射口都指向内桶3。
如图38所示，喷嘴10a右端面与挡水结构10b的左端面平行设置，以便使喷射口喷出的洗涤水形成扇形的瀑布状。或者，本领域技术人员也可以根据需要，使喷嘴10a和挡水结构10b彼此相邻的两个端面不平行。
虽然图中并未示出，但是本领域技术人员可以根据需要，使多个挡水结构10b中的部分或每一个面向喷嘴10a的一侧(图38中挡水结构10b的左侧)都沿着盖体211(或外桶2)的圆周方向倾斜设置，示例性地，图36中挡水结构10b面向喷嘴10a的一侧(图36中挡水结构10b的下侧)沿着图36中的左右方向倾斜设置，即图36中挡水结构10b的左侧低于右侧；并且图36中挡水结构10b面向喷嘴10a的一侧沿着图36中的上下方向也倾斜设置。以便挡水结构10b不仅能够将喷嘴10a喷出的洗涤水打散反射进内桶3中，还能够使洗涤水沿着内桶3的圆周方向倾斜地(如图39所示)喷进内桶3中，使洗涤水在内桶3的圆周方向上形成高度差(如图32所示)，进而使多个喷嘴10a喷出的洗涤水能够对浮出洗涤水液面的衣物进行立体地、全方位地喷淋，使洗涤水充分地浸润衣物，尤其是衣物随着波轮4的转动而转动时。
如图33和图34所示，多个喷嘴10a沿外桶盖21的周向等间距地、固定地连接到或者一体成型到盖体211上，并且每一个喷嘴10a都分别与环形腔212连通。进一步，每一个喷嘴10a的喷射口都指向内桶3。此外，本领域技术人员也可以根据需要，使多个喷嘴10a非等间距地设置在盖体211上。
如图36至图38所示，外桶盖21的盖体211的内侧还设置有环形的遮挡结构2111，该遮挡结构2111用于遮挡喷嘴10a和挡水结构10b，防止喷嘴10a挡水结构10b被用户观察到，以便优化外桶盖21的外观。
虽然图中并未示出，但是在本发明另一个可行的实施例中，本领域技术人员可以根据需要，将多个喷嘴10a和多个挡水结构10b直接地固定到外桶2的顶部，然后使循环水管9直接地或者借助其它水管与每一个喷嘴10a连通。
此外，虽然图中并未示出，但是在本发明喷淋***另一个可行的实施例中，本领域技术人员也可以根据需要，使外桶盖21上的进水口213通过水管与波轮洗衣机的进水阀连通。当进水阀的进水阀口与水龙头接通时，自来水能够沿着进水阀、水管和进水口213的路径提供给环形腔212，进而使喷嘴10a将自来水喷射到内桶3中的衣物上，湿润衣物。
进一步，本领域技术人员也可以根据需要，使本发明的喷淋***同时具有上述的循环泵8、循环水管9、进水阀以及连通进水阀和进水口213的水管，并且在进水阀和进水口213串联一个截止阀。此时，循环泵8和进水阀可以分别或共同作为供水设备。当需要自来水喷淋衣物时，进水阀和截止阀被打开。当需要外桶2中的洗涤水喷淋衣物时，循环泵8工作。
如图40至图42所示，在本发明的第二实施例中，与第一实施例不同的是，挡水结构10b面向喷嘴10a一侧设置有凹部10b1。优选地，该凹部10b1是具有弧形表面的凹部，即凹部10b1的内表面是弧形面。进一步优选地，挡水结构10b整体上为勺形结构。此外本领域技术人员也可以根据需要，将挡水结构10b设置成其它任意可行的结构，例如，具有凹面的板状结构或具有凹面的块状结构。
本领域技术人员能够理解的是，洗涤水从喷嘴10a喷出之后会呈束状地喷向凹部10b1内。落入凹部10b1内的洗涤水会从着落点沿着凹部10b1的弧面延展开来，最后从凹部10b1的边缘流出形成扇形的瀑布状水流(如图32和图39所示)并倾斜地落入内桶3中。
进一步，本领域技术人员也可以根据需要，使图42中喷嘴10a上端的环形面与图42中挡水结构10b下端(形成有凹部10b1的一端)的环形面平行设置，以便使喷射口喷出的洗涤水形成扇形的瀑布状。
更进一步，本领域技术人员还可以根据需要，使第二实施例中的挡水结构10b也同第一实施例中的挡水结构10b相同，沿外桶2的 圆周方向倾斜设置。即图42中挡水结构10b的左侧边缘距离图42中喷嘴10a下端面的距离大于或小于图42中挡水结构10b的右侧边缘距离图12中喷嘴10a下端面的距离。
如图43至图45所示，在本发明的第三实施例中，与第一实施例和第二实施例不同的是，喷嘴10a和挡水结构10b分体设置，即喷嘴10a和挡水结构10b在结构上不直接连接，彼此分离。为了使喷嘴10a和挡水结构10b对应地设置到一起，喷嘴10a和挡水结构10b分别固定到或一体成到盖体211上。
如图44和图45所示，在本发明的第三实施例中，与第一实施例相同的是，每一个挡水结构10b面向喷嘴10a的一侧(图44中挡水结构10b的下侧)都沿着盖体211的圆周方向倾斜设置，示例性地，图45中挡水结构10b面向喷嘴10a的一侧(图44中挡水结构10b的下侧)沿着图44中的左右方向倾斜设置(如图44中所示的夹角d)，并且图44和图45中挡水结构10b面向喷嘴10a的一侧)沿图44和着图45中的上下方向也倾斜设置。以便挡水结构10b不仅能够将喷嘴10a喷出的洗涤水打散反射进内桶3中，还能够使洗涤水沿着内桶3的圆周方向倾斜地(如图39所示)喷进内桶3中，使洗涤水在内桶3的圆周方向上形成高度差(如图32所示)，进而使多个喷嘴10a喷出的洗涤水能够对浮出洗涤水液面的衣物进行立体地、全方位地喷淋，使洗涤水充分地浸润衣物，尤其是衣物随着波轮4的转动而转动时。
需要说明的是，无论上述的第一实施例、第二实施例，还是第三实施例，喷嘴10a可以是任意可行的结构，例如圆管、锥形管、椭圆形管、多边形管等。
本领域技术人员能够理解的是，本发明的喷嘴10a和10b的组合形式不仅限于上述第一实施例、第二实施例和第三实施例，其还可以是该三个示例中的两个或三个的组合，或者其他任意可行的组合方式。
基于上述描述，本领域技术人员能够理解的是，本发明通过使挡水结构10b面向喷嘴10a的一侧沿外桶2的圆周方向倾斜设置，使得挡水结构10b反射的洗涤水不仅能够沿内桶3的径向倾斜地喷进内桶3中，还能够沿内桶3的圆周方向倾斜地喷进内桶中，使洗涤水在内桶3的圆周方向上形成高度差，进而使得多个喷嘴10a喷出的洗涤水能够对浮 出洗涤水液面的衣物进行立体地、全方位地喷淋，使洗涤水充分地浸润衣物，提高了波轮洗衣机的喷淋效果，优化了波轮洗衣机的洗涤效果。
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。
