Description

一种自旋转喷淋装置及洗衣机 技术领域
本发明涉及洗衣机技术领域，特别是涉及一种用于洗衣机的自旋转喷淋装置和具有其的洗衣机。
背景技术
现有的洗衣机的进水喷淋衣物装置、门窗喷淋装置和水循环喷淋装置，其喷淋头的喷淋范围小，喷淋效果差。
一般情况下，人们为了增强喷淋效果，将喷淋装置做大，或者安装多个喷淋装置。但是这样做既增加了喷淋装置占用的空间从而增加了洗衣机的体积，同时增加了水和能量的消耗。
申请号为201610514730.2的中国专利公开了一种用于洗衣机的喷淋装置和具有其的洗衣机，所述喷淋装置包括：进水管和喷淋头组件，喷淋头组件可旋转地设在进水管的出水端，且喷淋头组件的旋转中心轴为进水管的出水端的轴线，喷淋头组件内限定出导流腔，导流腔与进水管连通，且喷淋头组件上具有与导流腔连通的出水口，且出水口相对于旋转中心轴倾斜，导流腔内与进水管的出水端相对的表面上形成有导流面，在环绕旋转中心轴的一个方向上导流面朝远离进水管的出水端的方向倾斜。此喷淋装置虽然可以使出水口流出的水流形成360°全方位旋转喷淋，喷淋覆盖面积大，但是，喷淋面积大的同时会带来喷淋水流弱的问题。实际洗衣机工作中，喷淋范围在原喷淋方向基础上适当增加喷淋范围即可，而前述专利则大大削弱了原喷淋方向，喷淋效果相对不理想。
有鉴于此特提出本发明。

进一步的，所述喷淋出水一部分从所述本体上的周向喷孔喷出，所述本体上设置至少一个周向喷孔，优选的，所述周向喷孔周向均匀的分布在所述本体伸出出水口外的部分上，且各周向喷孔的形状、尺寸相同。

下面结合附图对本发明的具体实施方式作进一步的介绍。
如图1-图9所示，一种自旋转喷淋装置1，包括
喷淋头11，所述喷淋头11内设置供水流经过的通孔，所述通孔的一端为进水口111，另一端为出水口112，所述进水口111连接进水管路；
自旋转喷嘴12，所述自旋转喷嘴12设置在所述喷淋头11出水口112处的通孔内，所述自旋转喷嘴12包括中空的本体、设置在本体内的叶轮121和旋转轴122，所述本体的末端1213为主喷孔1231，所述本体123至少部分伸出出水口112外设置且该部分本体上设置有周向喷孔1232，喷淋水流冲击叶轮121使其转动，改变部分水流的喷淋出水方向。
在上述方案中，所述自旋转喷淋装置1适用于有喷淋需求的各种类型的洗衣机。本发明自旋转喷淋装置1可以在洗衣机的多处位置安装，如外筒壳体、门窗、密封窗垫3等。用于洗衣机的进水喷淋衣物、门窗喷淋和水循环喷淋等。所述自旋转喷淋装置1设有喷淋头11和自旋转喷嘴12，所述喷淋头11一端连接洗衣机的进水管路或者喷淋进水管路为进水口111，另一端喷淋出水为出水口112，所述进水口111与出水口112之间的通孔供喷淋水流经过。所述自旋转喷嘴12包括中空的本体、设置在本体内的叶轮121和旋转轴122。所述叶轮121和旋转轴122固定设置在所述本体内，则所述本体可旋转的设置在所述喷淋头11内；所述叶轮121可旋转的设置在所述本体内，则所述本体不可旋转的设置在所述喷淋头11内。所述本体的末端1213为主喷孔1231，所述本体123至少部分伸出出水口112外设置且该部分本体上设置有周向喷孔1232。所述喷淋水流一部分自所述本体123的主喷孔1231喷淋，一部分自所述本体上的周向喷孔1232喷淋。
进一步的，所述喷淋出水一部分从所述本体上的周向喷孔1232喷出，所述本体上设置至少一个周向喷孔1232，优选的，所述周向喷孔1232周向均匀的分布在所述本体伸出出水口 112外的部分上，且各周向喷孔1232的形状、尺寸相同。
在上述方案中，在本体上设置至少一个周向喷孔1232是为了增加喷淋的方向和角度，扩大喷淋范围。所述周向喷孔1232周向均匀的分布在所述本体伸出出水口112外的部分上，且各周向喷孔1232的形状、尺寸相同，是为了使周向喷孔1232的喷淋更加均匀，水流从每个周向喷孔1232喷出都会对自旋转喷嘴12本身产生一个反作用力，当喷孔形状、尺寸相同又均匀分布在所述自旋转喷嘴12的本体上时，水流喷出后的反作用力之间相互作用可以抵消，不会对自旋转喷嘴12本体产生单一方向上的力从而使其渐渐偏斜。
进一步的，所述喷淋出水一部分从自旋转喷嘴12本体123的主喷孔1231沿叶轮121的旋转轴线a在夹角A范围内喷淋，所述夹角A为所述叶轮121中心到主喷孔1231边缘的连线与叶轮121的旋转轴线a之间的夹角的两倍。
在上述方案中，当所述喷淋水流自喷淋头11的进水口111进入后，喷淋水流冲击叶轮121转动，转动的叶轮121具有扰流作用，改变水流方向使一部分水流沿着旋转轴122的轴线a，夹角A范围，喷淋。
进一步的，所述夹角A的大小与所述主喷孔1231的内半径R有关，与所述叶轮121中心到主喷孔1231边缘的距离L也有关，两者的比值R/L≥0.2，优选的，R≥2mm,L≤10mm。
在上述方案中，所述夹角A的大小与所述主喷孔1231的内半径R有关，内半径越大，所述夹角A越大；所述夹角A的大小与所述叶轮121中心到主喷孔1231边缘的距离L也有关，距离越大，夹角越小；两者的比值R/L≥0.2，两者的比值越大，喷淋的范围越大。
进一步的，所述叶轮121至少包括两片螺旋桨叶片1211，该螺旋桨叶片1211至少部分沿旋转轴122倾斜延伸，各螺旋桨叶片1211的倾斜延伸方向相同，优选的，各螺旋桨叶片1211的形状和尺寸相同，沿所述旋转轴122周向均匀分布。
在上述方案中，为实现所述自旋转喷嘴12在喷淋水流冲击下的自旋转，所述自旋转喷嘴12至少包括两片螺旋桨叶片1211，所述自旋转喷嘴12可包括两个螺旋桨叶片1211，也可以包括三个、四个或者五个、六个甚至更多螺旋桨叶片1211，但优选在三个到六个之间，不会因为螺旋桨叶片1211数量少而使降低自旋转的速度、力度和自旋转的可能性，也不会因为螺旋桨叶片1211数量太多而使结构复杂化。该螺旋桨叶片1211至少部分沿旋转轴122倾斜延伸，是为了在喷淋水流冲击时遇到阻力并将该阻力化为旋转的动力，所述螺旋桨叶片1211可以为全部沿旋转轴122倾斜延伸，也可以为部分沿旋转轴122倾斜延伸；各螺旋桨叶片1211 的倾斜延伸方向相同，是为了具有相同方向的旋转的动力，以免旋转动力的方向不同产生动力相互抵消而不能自旋转或自旋转的速度慢。上述方案中的优选实施例中，各螺旋桨叶片1211的形状和尺寸相同，沿所述旋转轴122周向均匀分布，都是为了得到相同方向的旋转动力，这种情况下，自旋转喷嘴12产生自旋转时没有其他形式产生的阻力，使自旋转更加流畅和容易。
进一步的，所述螺旋桨叶片1211的起始端1212沿旋转轴122平行延伸，其上端面垂直于旋转轴122；所述螺旋桨叶片1211的末端1213与起始端1212平行设置，所述一个螺旋桨叶片1211的起始端1212与其相邻螺旋桨叶片1211的末端1213之间的垂直旋转轴122方向的距离为B，该距离0≤B≤旋转轴122直径。
在上述方案中，所述螺旋桨叶片1211的起始端1212沿旋转轴122平行延伸，其上端面垂直于旋转轴122。是为了在水流一开始流经自旋转喷嘴12的时候对其进行引导和分流水流。所述螺旋桨叶片1211的末端1213与起始端1212平行设置，为了充分利用水流力并提高效率；所述一个螺旋桨叶片1211的起始端1212与其相邻螺旋桨叶片1211的末端1213之间的垂直旋转轴122方向的距离为B，该距离0≤B≤旋转轴122直径，为了充分利用水流力并提高效率的同时不对水流量造成干扰，这种情况下，水不会因为在螺旋桨叶片1211中流过太长的距离而降低流速和旋转速度等。同时还有一部分水通过距离B直接流出，增强了水流力。
进一步的，所述自旋转喷嘴12可拆卸的设置在所述喷淋头11出水口112处的通孔内，优选的，所述自旋转喷嘴12可旋转的卡接在所述喷淋头11出水口112处的通孔内，所述本体123的起始端1212外设有卡位环形凸台1233，所述喷淋头11内设置相匹配的卡接结构114，更优选的，所述卡接结构114处设置滚珠或者滚珠轴承。
在上述方案中，所述自旋转喷嘴12可拆卸的设置在所述喷淋头11出水口112处的通孔内，可拆卸的设置是为了方便所述自旋转喷淋装置1的维护，例如当喷淋结构被毛絮等堵塞等情况发生时，可拆卸自旋转喷嘴12进行疏通和清理毛絮等操作。所述本体123的起始端1212外设置的卡位环形凸台1233和与其相匹配设置在喷淋头11内的卡接结构114实现了所述自旋转喷嘴12的本体123可旋转。所述本体123的起始端1212外设有卡位环形凸台1233，所述喷淋头11内设置相匹配的卡接结构114，所述喷淋头11内设置的卡接结构114可以设置在喷淋头11内径不同的变径处，也可以在喷淋头11内设置卡接凹槽。为了避免自旋转喷嘴12高速旋转时对于结构的磨损等影响，所述卡位环形凸台1233与所述卡接结构114之间设置降低磨损的结构，优选的方式是在卡接结构114处设置滚珠或者滚珠轴承。
进一步的，所述旋转轴122、叶轮121与所述本体123一体成型；或者所述旋转轴122、叶轮121与所述本体123均固定连接。
在上述方案中，所述旋转轴122、叶轮121与所述本体123均一体成型，彼此之间不存在相对运动；所述旋转轴122、叶轮121与所述本体123均固定连接，则三者之间不存在相对的旋转运动。
进一步的，所述喷淋头11外设置限位结构113，限位安装所述自旋转喷淋装置1。
在上述方案中，所述喷淋头11可拆卸的设置在所述洗衣机内设置的安装孔2中，所述喷淋头11外设置限位结构113是为了限位所述喷淋头11在所述安装孔2中的安装，防止因喷淋开始后自旋转喷嘴12开始旋转带来的晃动等动作使所述喷淋头11安装不牢固或脱离安装或喷淋头11晃动范围大而影响喷淋效果等。所述限位结构113可以为环形限位凹槽，也可以为限位凹槽或凸起等，所述安装孔2中设置于限位凹槽或凸起等想配合的结构；或者限位结构113为与所述安装孔2相匹配的螺纹结构。
