Description

波轮洗衣机 技术领域
本发明涉及洗涤设备技术领域，具体而言，尤其涉及一种波轮洗衣机。
背景技术
波轮洗衣机在洗涤衣物时，一般会采用弱水流进行洗涤。波轮洗衣机在采用弱水流洗涤衣物时，存在衣物缠绕、磨损等问题，进而影响了波轮洗衣机的洗涤效果。未解决弱水流存在的洗衣问题，相关技术中，采用强水流对衣物进行清洗，例如，通过合理的洗涤程序可以控制洗衣机内筒高速旋转以产生较强的离心力，进而使得洗衣机内筒顶部喷出旋转的强劲水流来解决上述问题。波轮洗衣机在采用强水流进行洗涤衣物时，洗涤用水容易从内筒和外筒之间的上端的间隙甩溅出，容易对波轮洗衣机内部的电路造成意外损害，进而影响波轮洗衣机的使用性。
发明内容
本发明旨在至少在一定程度上解决相关技术中的技术问题之一。为此，本发明提出一种波轮洗衣机，所述波轮洗衣机具有使用性能好、安全性好的优点。

根据本发明的波轮洗衣机，通过将环形筒盖设在筒体的上端，且环形筒盖的下端面上位于内筒内部的部分从外向内逐渐向下倾斜，使得沿环形筒盖的下端面向内筒内流动的水可以以一定的速度进入到内筒内，从而提高了水流对内筒内部的衣物的冲击力。同时也可以使洗涤剂充分溶解，进而提高了波轮洗衣机的洗涤效果。
根据本发明的一个示例，所述环形筒盖的所述下端面的最内端的切线与水平面之间的夹角为α，所述α满足：25°≤α≤45°。

具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本发明，而不能理解为对本发明的限制。
下面参照图1-图4详细描述根据本发明实施例的波轮洗衣机100。
如图1-图4所示，根据本发明实施例的波轮洗衣机100，包括：筒体110和环形筒盖120。
具体而言，筒体110包括外筒111和内筒112，内筒112设在外筒111内并可相对于外筒111旋转，内筒112的外壁与外筒111的内壁之间形成有排水通道113。换言之，设置在外筒111内的内筒112的底壁与外筒111的底壁之间形成有第一空间114，同时内筒112的周壁与外筒111的周壁之间形成有第二空间115，第一空间114与第二空间115相通，第一空间114与第二空间115共同组成排水通道113。
内筒112内部与排水通道113连通。例如，内筒112的侧壁上设有多个间隔开的、且贯穿内筒112侧壁的通孔116，内筒112内的水可以通过通孔116进入到排水通道113，并由排水通道113排出。同时排水通道113内的水也可以通过通孔116进入到内筒112内，由此可以增强水流对内筒112内的衣物的冲洗作用，同时也可以使洗涤剂充分溶解。在本发明的一个实施例中，内筒112下部设有多个位于排水通道113内的排水翼117，多个排水翼117凸出于内筒112外表面且沿内筒112周向方向间隔开。优选地，排水翼117可以与内筒112一体成形。
如图1和图4所示，环形筒盖120设在筒体110的上端，且环形筒盖120的内端部分向内延伸到内筒112的上方，环形筒盖120的下端面121上位于内筒112内部的部分从外向内逐渐向下倾斜。如图1所示，环形筒盖120对第二空间115向上行进的水起到限制作用，使第二空间115内向上行进的水可以在环形筒盖120的阻挡下直接进入到内筒112内。当使用强水流进行洗涤或水行进到排水通道113的上端时，将会被环形筒盖120的下端面121遮挡住，一部分水在重力的作用下将返回到排水通道113内，另一部分水将会沿着环形筒盖120的下端面121流向环形筒盖120的内周缘125，最终流入到内筒112内。由此，可以有效地避免洗涤用水外溅的现象发生。
由于环形筒盖120的下端面121上位于内筒112内部的部分从外向内逐渐向下倾斜，沿环形筒盖120的下端面121向内筒112内流动的水可以以一定的速度进入到内筒112内，进而提高了水流对内筒112内部的衣物的冲击力，同时也可以使洗涤剂充分溶解，从而提高了波轮洗衣机100的洗涤效果。
根据本发明实施例的波轮洗衣机100，通过将环形筒盖120设在筒体110的上端，且环形筒盖120的下端面121上位于内筒112内部的部分从外向内逐渐向下倾斜，使得沿环形筒盖120的下端面121向内筒112内流动的水可以以一定的速度进入到内筒112内，从而提高了水流对内筒112内部的衣物的冲击力。同时也可以使洗涤剂充分溶解，进而提高了波轮洗衣机100的洗涤效果。
如图1-图4所示，根据本发明的一个实施例，环形筒盖120的下端面121的最内端的 切线与水平面之间的夹角为α，α满足：25°≤α≤45°。由此，可使水流不会因相互碰撞或冲击筒体110而产生水花飞溅，并将水流引导至内筒112内部，提高了波轮洗衣机100的洗涤效果，同时也可以形成良好的视觉效果。优选地，α为35°。经试验验证，当α＝35°时，环形筒盖120的引导水流的效果更好，环形筒盖120的外形也更加符合用户的审美习惯。
为方便将环形筒盖120连接在筒体110上，如图2所示，环形筒盖120的外周壁上设有适于扣合至外筒111的上端的卡扣件122。可选地，卡扣件122可以为形成在环形筒盖120的外周缘126处的环形凹槽，环形凹槽的敞开口朝向外筒111的底部，外筒111的上端插接在环形凹槽内部。由此，可以有效地防止水流从环形筒盖120的外周缘126处逸出。
当然，环形筒盖120与筒体110的连接方式并不限于此，例如，在本发明的另一个示例中，如图3和图4所示，环形筒盖120的外周壁上设有朝向环形筒盖120径向外侧凸出的第一凸缘124，外筒111的靠近外筒111的上端的外周壁上设有朝向外筒111径向外侧凸出的第二凸缘，第一凸缘124和第二凸缘可以通过螺栓连接。由此，保证了环形筒盖120与外筒111上端连接的可靠性和密封性。优选地，第一凸缘124为多个且沿环形筒盖120的周向方向间隔分布，第二凸缘与第一凸缘124一一对应。如图2所示，环形筒盖120的下端面121为弧形面，由此在第二空间115内向上行进的水可以在环形筒盖120的下端面121的阻挡下直接进入到内筒112内部。为方便加工，优选地，环形筒盖120的上端面127与下端面121平行。
进一步地，为提高环形筒盖120的引导水流的效果，如图2和图3所示，环形筒盖120的下端面121上设有多条导水筋条123，多条导水筋条123沿内筒112的周向方向间隔地分布在下端面121上以将位于环形筒盖120的径向外侧的水引导至环形筒盖120的径向内侧。如图2和图3所示，波轮洗衣机100在洗涤衣物的过程中，内筒112在外筒111内部旋转，内筒112中的水由于离心力以及排水翼117的作用进入到排水通道113内，随着水位的上升，水流被甩到环形筒盖120的下端面121上，在导水筋条123的引导下，水流将沿着导水筋条123喷射到内筒112内部，从而可以对衣物进行强力冲刷洗涤，对洗涤剂施加强大的机械力作用使其充分溶解，并可以打散衣物，降低衣物的缠绕，波轮洗衣机100无负载运行时，还可以起到洁净筒体110的作用。
可选地，如图2和图3所示，在沿环形筒盖120的径向、从外到内的方向上，导水筋条123的高度逐渐增大。这里的“高度”可以指，导水筋条123在如图2中所示的上下方向上的长度，即导水筋条123在内筒112中心轴线上的长度。由此，有利于将水流引导至内筒112内部，同时也可以提高水流脱离环形筒盖120内周缘125时的速度，进而提高水流对内筒112内部的衣物的冲击力，使洗涤剂充分溶解。优选地，在水平面投影面上，导水筋条 123可以为弧线形。这里的“水平投影面”可以是与图3所在的平面平行的平面。由此，可以进一步提高水流脱离环形筒盖120内周缘125时的速度，进而提高水流对内筒112内部的衣物的冲击力，进一步使洗涤剂溶解。
如图3所示，导水筋条123的靠近环形筒盖120的内周缘125的一端的切线为a，过该导水筋条123的该端的环形筒盖120的径向参考线为b，a与b之间的夹角为β，β满足：20°≤β≤40°。需要说明的是，导水筋条123的靠近环形筒盖120的内周缘125的一端的端点为A，该导水筋条123上A点处的切线为a。这里“环形筒盖120的径向参考线”可以指过环形筒盖120的中心点B、且过点A的直线。也就是说，波轮洗衣机100在工作状态下，沿着排水通道113向上(如图1所示的上方)行进的水流，在导水筋条123的引导下，从环形筒盖120的内周缘125处喷射至内筒112的内部，此时，水流的喷射方向为导水筋条123的靠近环形筒盖120的内周缘125的一端切线方向，该处水流的运动轨迹为直线a。直线a与环形筒盖120的径向参考线b之间的夹角为β，且β满足：20°≤β≤40°。由此，有利于将水流引导至内筒112内部，也可以提高水流脱离环形筒盖120内周缘125时的速度，进而提高水流对内筒112内部的衣物的冲击力，使洗涤剂充分溶解，使得衣物洗涤更快、更省电、省水，同时也降低了能耗。
