相关申请的交叉引用
本申请基于申请号为201910110091.7和201920190398.8，申请日为2019年2月11日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及衣物处理技术领域，具体而言，涉及一种洗衣机的旋转桶组件和洗衣机。
背景技术
随着洗衣机技术的不断发展，洗衣机已经越来越趋向于大容量，而在洗衣机逐渐趋于大容量的同时，必然会导致洗衣机整体尺寸的增大，所以提供一种小体积大容量的洗衣机很有必要；于此同时，现有的洗衣机在洗涤时水分布在旋转桶和盛水桶内，即盛水桶和旋转桶也之间分布有水，用水量较大，造成水资源的浪费；现有的洗衣机污垢易留存在盛水桶和旋转桶之间，从而滋生细菌并且因为盛水桶和旋转桶之间分布有水，对于洗涤剂的用量也较多，造成洗涤剂的资源浪费，不利于节约成本。
为此，相关技术提出了省去盛水桶而仅保留旋转桶的洗衣机，其在旋转桶的内周壁面设置导水罩，在脱水过程中，旋转桶内的水在离心力的作用下先向上爬升，然后通过导水罩在重力作用下下落排出。但由于在整个脱水过程中，均有离心力的参与，因此无法兼顾水在爬升和下落过程中离心力的影响，导致脱水效果较差；此外，仅设置旋转桶的结构使得整体结构强度较低，长期进行脱水等过程后易变形，影响用户使用效果，存在改进空间。

根据本申请实施例的用于洗衣机的旋转桶组件200，通过将旋转桶210的内直径设置成由下至上逐渐增大，使得旋转桶210在旋转过程中，有利于液体在离心力的作用下更易沿旋转桶210的周壁2101上升至进水口221处；通过将导水结构260设置成外凸的结构，使得导水腔240内离心力大于旋转桶210内的离心力，从而使得水更易流入导水腔240内，而不会再次流入旋转桶210内，提高了脱水效果；通过设置引导部230，增大了导水腔240上方的空腔体积，即提高了水的容纳量，使得水更容易流入，而不会再次从进水口221处流入旋转桶210内，节约了脱水时间，提高了脱水效率，同时降低了被洗涤衣物的含水率，提高了脱水效果。
如图1和图2所示，根据本申请的一个实施例，引导部230在旋转桶210圆周方向上的投影长度大于导水结构260在旋转桶210圆周方向上的投影长度，以增大了导水腔240上方的空腔体积，增大进水量，即在圆周方向上，引导部230向导水结构260的任意一侧延伸一定的距离，或引导部230向导水结构260的两侧延伸一定的距离。当然，导引部230也可以在旋转桶210的径向上的投影长度大于导水结构260在旋转桶210径向上的投影长度，从而也可以增大导水腔240上方的空腔体积。
在一些具体的示例中，引导部230的一部分在圆周方向上向导水结构260的两侧延伸，引导部230位于导水结构260的上方且引导部230与导水结构260连接起来呈T字形，因为引导部230朝旋转桶210的外侧凸出设置且引导部230在圆周方向上向导水结构260的两侧延伸一定的距离，进而增大了引导部230内的空腔体积，使得旋转桶210内因离心力作用而上升的液体很容易进入到引导部230内，而不会再次从进水口221处流入旋转桶210内，节约了脱水时间，提高了脱水效率，同时降低了被洗涤衣物的含水率，提高了脱水效果。
其中，引导部230向导水结构260的两侧延伸的距离相同，从而使得结构美观，制造工艺简单；引导部230与导水结构260的顶部圆滑过渡连接，且引导部230与导水结构260可以为一体成型结构，即便于制造成型，又使得引导部230与导水结构260均匀过渡，从而使得进入引导部230内的液体可以及时地流至导水腔240和/或导水结构260内。
旋转桶210的引导部230处的上下方向的轮廓线可以形成沿上下方向延伸的竖直线，也可以形成相对于上下方向由上至下逐渐向外倾斜延伸的倾斜直线，该轮廓线与旋转桶210的导水结构260处的上下方向的轮廓线平滑过渡连接，即引导部230在纵向上的延伸方向与导水结构260在纵向上的延伸方向相同。
因旋转桶210构造成上大下小的锥形(圆台形)，旋转桶210的导水结构260处的上下方向的轮廓线可以形成沿上下方向延伸的竖直线，也可以形成相对于上下方向由上 至下逐渐向外倾斜延伸的倾斜直线，虽然引导部230在圆周方向上向导水结构260的两侧延伸一定的距离，但导水结构260的内部空间自上而下是逐渐增大的，可以保证脱水时，旋转桶210内因离心力作用而上升的液体很顺畅的从进水口221流入，从出水口211流出，从而提高了脱水效率且降低了被洗涤衣物的含水率，同时节约了脱水时间。
根据本申请的一个实施例，导水结构260上具有加强结构，通过在导水结构260上形成加强结构，提高了导水结构260的结构强度，使旋转桶210的结构强度高、不易变形，保证了脱水过程中结构的稳定性，进一步保证了脱水效果。
如图1和图7所示，根据本申请的一个实施例，导水结构260的下表面形成为三角形，该结构构成加强结构的至少一部分，利用三角形的稳定性，提高导水结构260的结构强度，保证脱水过程中整体结构的稳定性，提高脱水效果。
如图2和图8所示，根据本申请的一个实施例，导水结构260包括：第一导水段261、中间导水段263和第二导水段262，第一导水段261、中间导水段263和第二导水段262沿旋转桶210的周向依次设置，中间导水段263的两端分别与第一导水段261和第二导水段262过渡连接，通过在导水结构260形成三个导水段，通过导水段增强导水结构260的结构强度，使其稳定不易变形。
如图8所示，在一些示例中，中间导水段263的横截面轮廓线形成弧线形，该弧线以旋转桶210的中心为圆心，即使得中间导水段263形成光滑的圆弧段，且中间导水段263的半径略大于旋转桶210在该横截面处的半径，既使得水在离心力的作用下更易流至中间导水段263处，提高脱水效果；又便于中间导水段263的制造成型，简化了制造工艺。
在一些示例中，中间导水段263在上下方向上的各处的内直径一致，即中间导水段263的任一处的内直径均等于中间导水段263的最上方部分的内直径，在导水结构260的纵向剖视图上、中间导水段263的内侧形成竖直段，导水腔240内的一部分形成垂直腔，即在保证了导水腔240的导水效果和结构强度的基础上，进一步简化了中间导水段263的结构，便于其制造成型。
在另一些示例中，中间导水段263的内直径由上至下逐渐增大，即中间导水段263的任一处的内直径均大于中间导水段263的位于该处上方部分的内直径，在导水结构260的纵向剖视图上、中间导水段263的内侧形成逐渐向外(如图6中所示的外侧，即远离旋转桶210中心的一侧)倾斜的倾斜段，由此，使得导水腔240内底部的离心力大于其顶部的离心力，从而使得进入导水腔240内的水更容易到达其底部并排出至外界，进一步提高了脱水效果。
根据本申请的一个实施例，中间导水段263的横截面轮廓线的长度与导水结构260 的横截面轮廓线的长度的比值、在上下方向上由上至下逐渐减小，在导水结构260的上端、中间导水段263的横截面轮廓线的长度最大；如图1所示，中间导水段263的横截面轮廓线的长度从上至下逐渐减小，第一导水段261和第二导水段262的横截面轮廓线的长度从上至下逐渐增大。
在一些示例中，如图6和图7所示，图中示出了导水结构260底部的横截面轮廓线，在导水结构260的下端、中间导水段263的长度接近为零，第一导水段261、第二导水段262和导水罩220/或旋转桶210之间形成三角形，即在出水口211处、导水腔240的横截面形成三角形，由此提高导水结构260的结构强度；且此处导水腔240横截面面积大于位于该处上方部分的横截面面积，保证进入导水腔240内的水可以及时流出，由此保证脱水效果。
在一些示例中，第一导水段261的横截面轮廓线形成斜线形，在朝远离中间导水段263的方向上、该斜线逐渐向旋转桶210的中心延伸，如图8所示，第一导水段261位于中间导水段263的左侧，从右向左、第一导水段261的横截面轮廓线逐渐向内倾斜延伸，从而使第一导水段261与旋转桶210圆滑过渡连接，避免形成棱角影响结构强度。
在另一些示例中，第二导水段262的横截面轮廓线也形成斜线形，在朝远离中间导水段263的方向上、该斜线逐渐向旋转桶210的中心延伸，如图8所示，第二导水段262位于中间导水段263的右侧，从左向右、第二导水段262的横截面轮廓线也逐渐向内倾斜延伸，从而使第二导水段262与旋转桶210圆滑过渡连接，避免形成棱角影响结构强度。
如图7和图8所示，在一些示例中，第一导水段261和第二导水段262关于中间导水段263的中心线对称布置，即导水结构260沿中间导水段263的中心线对称设置，从而在保证了脱水效果的情况下，进一步简化了导水结构260的制造工艺，降低了制造难度，同时提高了结构的稳定性。
根据本申请的一个实施例，旋转桶210在导水结构260处的上下方向的轮廓线与旋转桶210在其余位置处的上下方向的轮廓线之间的距离由上至下逐渐增大。
可以理解的是，旋转桶210在导水结构260处的上下方向的轮廓线以及旋转桶210在其余位置处的上下方向的轮廓线均形成直线，由于旋转桶210构造成上大下小的锥形，因而旋转桶210在导水结构260处的上下方向的轮廓线可以形成沿上下方向延伸的竖直线，也可以形成相对于上下方向由上至下逐渐向外倾斜延伸的倾斜直线，或者形成相对于上下方向由上至下逐渐向内倾斜延伸的倾斜直线。
根据本申请的一个实施例，进水口221设于导水罩220上，出水口211设置导水结构260和/或旋转桶210的底壁，即出水口211可以设置在导水结构260上，也可以设 置在旋转桶210的底壁上，或者出水口211设置在导水结构260和旋转桶210上。
具体的，出水口211设置在导水结构260上，这样导水罩220罩设出水口211，且导水罩220的下端仅与导水结构260连接，利于导水罩220的密封。当然，本申请中的出水口211也可以设置在旋转桶210的底壁上，导水罩220罩设出水口211，利于提高脱水时的脱水效率，脱水效果好，并且可以有效的减少水从出水口211中的飞溅；当出水口211设置在导水结构260和旋转桶210的底壁上时，既利于导水罩220的密封，也利于提高脱水时的脱水效率，并且可以有效的防止水从出水口211中飞溅出来。
在一些实施例中，进水口221设在导水罩220的上部，出水口211设置在导水结构260的下部。这里可以理解地是，导水罩220的上部是指，导水罩220的在上下方向上的中心以上的部分，导水结构260的下部是指，导水结构260的在上下方向上的中心以下的部分，由此，脱水时，旋转桶210旋转，旋转桶210内的水在离心力的作用下上升，位于导水罩220上部的进水口221能够更好地收集上升的水，这部分水由进水口221进入导水罩220内，并在导水罩220的引导下流至下方的出水口211，从而进一步提高脱水效率和脱净效果。
更在一些实施例中，如图1所示，进水口221设在导水罩220的上端，以进一步便于收集旋转桶210内在离心力作用下上升到旋转桶210上端的液体，出水口211设在导水结构260且邻近旋转桶210的底壁设置，出水口211与旋转桶210的底壁间隔预定距离，由此，便于导水罩220的密封。
根据本申请的一个实施例，导水罩220的导水腔240由导水罩220单独限定出或由导水罩220和导水结构260共同限定出。换言之，导水罩220内可以限定出一个完整的导水腔240，并在导水罩220上开设连通导水腔240和出水口211的通孔；或者，导水罩220内限定出一面敞开的导水腔240，导水罩220安装在导水结构260上时，由导水结构260封闭导水腔240的敞开的一面。
根据本申请的一个实施例，如图1和图6所示，为了提高旋转桶210的脱水效果，导水结构260为多个，且多个导水结构260沿旋转桶210的周向间隔设置，导水罩220为多个，且多个导水罩220分别设于多个导水结构260，即导水结构260与导水罩220的数量对应，每个导水结构260上均安装有导水罩220。
在一些示例中，导水结构260为两个，两个导水结构260在旋转桶210的径向上相对设置，导水罩220为两个，两个导水罩220分别一一对应地设于两个导水结构260。
根据本申请实施例的洗衣机(图中未示出)，包括：箱体(图中未示出)以及根据本申请实施例的洗衣机的旋转桶组件200，旋转桶组件200可旋转地设在箱体内，通过采用上述旋转桶组件200，提高了洗衣机的结构强度，同时进一步提高了脱水效果。
本领域的技术人员可以理解地是，根据本申请实施的用于洗衣机的旋转桶组件200，可以用于单桶洗衣机，也可以用于双桶洗衣机，本申请对此并不做限制。
根据本申请的一个实施例，洗衣机可以为波轮洗衣机，通过在波轮洗衣机的旋转桶200上设置加强结构，增强了整体结构强度，使其不易发生变形，保证了洗涤效果和脱水效果，提高了用户的使用体验。
下面参考图1-图8描述根据本申请的一个具体的实施例。
洗衣机包括箱体和旋转桶组件200。旋转桶组件200包括旋转桶210和导水罩220。
旋转桶210形成为上大下小的倒圆台形，旋转桶210的内直径由下至上逐渐增大，旋转桶210的周壁2101具有多个向外凸出的导水结构260，多个导水结构260沿旋转桶210的周向间隔设置，其中，旋转桶210在导水结构260处的上下方向的轮廓线形成沿上下方向延伸的竖直线。
导水罩220位于旋转桶210内，导水罩220设置在导水结构260上，导水罩220和旋转桶210的导水结构260共同限定出导水腔240，导水罩220的上端和导水结构260之间限定出进水口221，进水口221便于收集旋转桶210内在离心力作用下上升到旋转桶210上端的液体；导水腔240的出水口211设置在导水结构260的底部，进入导水腔240内的液体可以通过出水口211及时排出。
导水结构260上具有加强结构，具体地，加强结构包括第一导水段261、中间导水段263和第二导水段262，第一导水段261、中间导水段263和第二导水段262沿旋转桶210的周向依次设置，中间导水段263的两端分别与第一导水段261和第二导水段262过渡连接，第一导水段261的另一端和第二导水段262的另一端分别与旋转桶210圆滑过渡连接。
中间导水段263的横截面轮廓线形成以旋转桶210的中心为圆心的弧线形，且在导水结构260的上端、中间导水段263的横截面轮廓线的长度最大，在导水结构260的下端、中间导水段263的长度接近为零，沿从上向下的方向、中间导水段263的横截面轮廓线的长度逐渐减小；沿上下方向、中间导水段263的内侧为竖直线，以使中间导水段263在上下方向上的各处的内直径一致。
第一导水段261和第二导水段262关于中间导水段263的中心线对称布置，第一导水段261和第二导水段262的横截面轮廓线均形成斜线形，在朝远离中间导水段263的方向上、该斜线逐渐向旋转桶210的中心延伸，在导水结构260的上端，第一导水段261和第二导水段262的横截面轮廓线的长度最小，在导水结构260的下端、第一导水段261和第二导水段262的横截面轮廓线的长度最大，且在出水口211处，导水罩220、第一导水段261和第二导水段262的横截面组成为三角形，以此提高导水结构260的强度。
如图1和图2所示，根据本申请的一个实施例，旋转桶210的周壁2101还形成有朝旋转桶210的外侧凸出设置且位于导水结构260上方的引导部230，引导部230与导水结构260连通且引导部230与进水口221连通，旋转桶210内因离心力作用而上升的液体可以通过进水口221并经引导部230流入导水腔240和/或导水结构260内。引导部230在旋转桶210圆周方向上的投影长度大于导水结构260在旋转桶210圆周方向上的投影长度，即在圆周方向上，引导部230向导水结构260的两侧延伸一定的距离，引导部230位于导水结构260的上方且引导部230与导水结构260连接起来呈T字形，因为引导部230朝旋转桶210的外侧凸出设置且引导部230在圆周方向上向导水结构260的两侧延伸一定的距离，进而增大了引导部230内的空腔体积，使得旋转桶210内因离心力作用而上升的液体很容易进入到引导部230内，而不会再次从进水口221处流入旋转桶210内，节约了脱水时间，提高了脱水效率，同时降低了被洗涤衣物的含水率，提高了脱水效果。
其中，引导部230向导水结构260的两侧延伸的距离相同，从而使得结构美观，制造工艺简单；引导部230与导水结构260的顶部圆滑过渡连接，且引导部230与导水结构260可以为一体成型结构，即便于制造成型，又使得引导部230与导水结构260均匀过渡，从而使得进入引导部230内的液体可以及时地流至导水腔240和/或导水结构260内。
旋转桶210的引导部230处的上下方向的轮廓线可以形成沿上下方向延伸的竖直线，也可以形成相对于上下方向由上至下逐渐向外倾斜延伸的倾斜直线，该轮廓线与旋转桶210的导水结构260处的上下方向的轮廓线平滑过渡连接，即引导部230在纵向上的延伸方向与导水结构260在纵向上的延伸方向相同。
因旋转桶210构造成上大下小的锥形(圆台形)，旋转桶210的导水结构260处的上下方向的轮廓线可以形成沿上下方向延伸的竖直线，也可以形成相对于上下方向由上至下逐渐向外倾斜延伸的倾斜直线，虽然引导部230在圆周方向上向导水结构260的两侧延伸一定的距离，但导水结构260的内部空间自上而下是逐渐增大的，可以保证脱水时，旋转桶210内因离心力作用而上升的液体很顺畅的从进水口221流入，从出水口211流出，从而提高了脱水效率且降低了被洗涤衣物的含水率，同时节约了脱水时间。
根据本申请实施例的洗衣机，采用单桶结构，即仅设置旋转桶210而不设置盛水桶，这样洗涤时水在旋转桶210内，更加节水；通过进一步在旋转桶210的周壁2101上设置导水罩220，且限定出导水腔240，脱水时旋转桶210内的水在离心力的作用下上升，并由进水口221进入导水腔240内，在导水腔240的引导下流至出水口211，从而通过出水口211排出，由此，在取消盛水桶以简化结构、提升容量、减少污垢和细菌滋生、 节水的情况下，同时能够提高脱水效果。
并且，通过设置倒圆台形的旋转桶210和凸出旋转桶210的导水结构260，能够兼顾水在爬升和下落过程中离心力的影响，提高脱水效果，通过在导水结构260上设置加强结构，进一步提高了整体结构的强度，使其不易变形，保证脱水过程的稳定性，提高脱水效果。
此外，导水罩220连接在旋转桶210上，无需在箱体上设置额外结构或将箱体设置成内部和外部的双层结构以在脱水过程中实现导水，这样箱体的材料选取不再受限，例如可采用钣金等材料，从而大幅提升外观。
根据本申请实施例的洗衣机的其他构成以及操作对于本领域普通技术人员而言都是已知的，这里不再详细描述。
在本申请的描述中，除非另有明确的规定和限定，第一特征在第二特征“之上”或“之下”可以包括第一和第二特征直接接触，也可以包括第一和第二特征不是直接接触而是通过它们之间的另外的特征接触。而且，第一特征在第二特征“之上”、“上方”和“上面”包括第一特征在第二特征正上方和斜上方，或仅仅表示第一特征水平高度高于第二特征。
