本申请基于“申请号为201910324564.3，申请日为2019年04月22日”的中国专利申请提出，并要求上述中国专利申请的优先权，上述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
本申请涉及洗衣机技术领域，尤其是涉及一种洗衣机的旋转桶组件以及洗衣机。
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，但脱水不高，并且在脱水时由于水无法及时排出，容易在平衡圈下方形成积水而导致出现偏心问题，严重时会撞击洗衣机的箱体，安全性低。

具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
下面参考图1-图6描述根据本申请实施例的洗衣机的旋转桶组件200以及洗衣机1。
如图2-图6所示，根据本申请实施例的洗衣机的旋转桶组件200包括：旋转桶210 和导水罩220。
旋转桶210的周壁形成有导水结构260，导水结构260朝旋转桶210的外侧凸出设置，导水罩220设于旋转桶210内，导水罩220自身限定出排水通道240，或者导水罩220与旋转桶210共同限定出排水通道240，排水通道240具有进水口221和出水口211，排水通道240的进水口221位于排水通道240的出水口211的上方，进水口221的下沿低于导水结构260的上沿。
脱水时，旋转桶210因离心力作用而上升的液体通过进水口221进入排水通道240内，然后在重力的作用下通过出水口211排出。通过将导水罩220连接在旋转桶210上，无需在洗衣机1的箱体100上设置额外结构或将箱体100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100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旋转桶组件200，旋转桶210内的水在离心力的作用下先向上爬升，然后从进水口221进入排水通道240内，并在重力作用下下落从出水口211排出，通过将进水口221的下沿设置为低于导水结构260的上沿，保证脱水时水流可以顺利进入排水通道240内，减少水流回流到旋转桶210内的概率，从而减少脱水时间，提高脱水效率。
如图5和图6所示，根据本申请的一个实施例，旋转桶210的内壁面的上部具有凸部212，凸部212沿旋转桶210的周向延伸，例如凸部212可以形成沿旋转桶210的周向延伸的环形。旋转桶组件200还包括平衡圈270，平衡圈270连接于旋转桶210，且平衡圈270位于凸部212的上方。例如，平衡圈270设于旋转桶210内且与旋转桶210密封连接，平衡圈270支撑在凸部212的上方。
其中，导水结构260位于凸部212的下方，凸部212的下沿与进水口221的下沿之间的距离h2大于凸部212的下沿与导水结构260的上沿之间的距离h1，保证脱水时水流可以顺利进入排水通道240内，减少水流回流到旋转桶210内的概率，从而减少脱水时间，提高脱水效率。此外，还可以避免在平衡圈270下方形成积水而出现偏心现象，减少旋转桶210撞击洗衣机1的箱体的几率，提高洗衣机1脱水时的安全性。
在一些实施例中，旋转桶210的周壁向内凹陷设置，从而在旋转桶210的外壁面形成凹部213，并在旋转桶210的内壁面形成凸部212，结构简单、成型方便。在本实施例中，旋转桶210的外壁面形成有环形凹部213，旋转桶210的内壁面形成有环形凸部212。
在一些示例中，凸部212的下沿与旋转桶210的内壁面相邻的部分圆弧过渡连接，导水结构260的上沿与旋转桶210的内壁面相邻的部分圆弧过渡连接，加工、制造容易， 不仅提升旋转桶210的外观，而且利于提高导水效果。
根据本申请的一个实施例，在排水通道240内的液体的流动方向上，排水通道240的位于上游位置的通流面积小于排水通道240的位于下游位置的通流面积。
在一些示例中，排水通道240的通流面积在排水通道240内的液体的流动方向上逐渐增大。举例而言，排水通道240沿旋转桶210的轴向(如图2和图4所示的上下方向)延伸，排水通道240的通流面积沿从上到下的方向逐渐增大，从而保证水可以顺利排出，防止在旋转桶210的上部出现积水问题而导致旋转桶210发生偏心现象，保证脱水时的安全性。
由此，通过将排水通道240的位于上游位置的通流面积设置成小于其位于下游位置的通流面积，保证在排水过程中，水可以及时排出，防止出现旋转桶210上方因积水而导致旋转桶210发生偏心，避免旋转桶210在工作时撞击洗衣机的箱体，保证脱水时的安全性，提升用户使用体验。
可选地，排水通道240的横截面形状为三角形。例如，导水罩220形成朝远离旋转桶210的中心的方向弯曲的弧形盖板，导水罩220与旋转桶210之间限定出一边为弧形的三角形，结构稳定、可靠。
根据本申请的一个实施例，如图2和图4所示，旋转桶210的内直径由下至上逐渐增大。也就是说，旋转桶210可以构造成上大下小的倒圆台形，能够利于水向上爬升而进入排水通道240内，从而提高脱水效果。
如图2-图6所示，导水罩220设于导水结构260处。由此，通过设置倒圆台形的旋转桶210和凸出旋转桶210的周壁的导水结构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。
其中，如图2所示，导水结构260上具有加强结构，例如导水结构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。
根据本申请的一个实施例，如图3所示，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。
在一些实施例中，中间导水段263的横截面的外轮廓线形成弧线形，该弧线以旋转桶210的中心为圆心，即，使得中间导水段263的横截面的外轮廓线形成光滑的圆弧段， 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的任一处的内直径均不小于中间导水段263的位于该处上方部分的内直径。
例如，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，排水通道240内的一部分形成垂直腔，即在保证了排水通道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。
再如，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倾斜的倾斜段，由此，使得排水通道240内底部的离心力大于其顶部的离心力，从而使得进入排水通道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。
在一些实施例中，中间导水段263的横截面的外轮廓线的长度与导水结构260的横截面的外轮廓线的长度的比值在上下方向上由上至下逐渐减小。
换言之，在导水结构260的上端、中间导水段263的横截面的外轮廓线的长度最大；在导水结构260的下端、中间导水段263的长度接近为零，且在该位置处，第一导水段261、第二导水段262和导水罩220之间形成三角形，即在出水口211处、排水通道240的横截面形成三角形，由此提高导水结构260的结构强度；且此处排水通道240横截面面积大于位于该处上方部分的横截面面积，保证进入排水通道240内的水可以及时流出，由此保证脱水效果。
在一些实施例中，第一导水段261和/或第二导水段262的横截面的外轮廓线形成斜线形，且该斜线形在朝远离中间导水段263的方向上逐渐向旋转桶210的中心延伸的斜线形。
在一些实施例中，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。
根据本申请进一步的实施例，如图5所示，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。
通过将出水口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，并且可以有效地减少水从出水口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，又利于提高脱水时的脱水效率，并且可以有效地防止水从出水口211中飞溅出来。
进一步地，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进行旋转，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。
更进一步地，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。
为了提高旋转桶210的脱水效果，导水结构260设置为多个，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220一一对应地设于多个导水结构260处。
如图4和图5所示所示，在本实施例中，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处。
如图2所示，根据本申请的一个实施例，旋转桶210的周壁还形成有朝旋转桶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流入排水通道240和/或导水结构260内。
在一些示例中，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。
在一些具体示例中，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排水通道240和/或导水结构260内。
其中，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构造成上大下小的倒圆台形，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。
如图1所示，根据本申请实施例的洗衣机1包括箱体100以及根据上述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100内。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1，也可以用于双桶洗衣机1，本申请对此并不做限制。
根据本申请实施例的洗衣机1，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的内周壁面上设置导水罩220，且限定出排水通道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进入排水通道240内，在排水通道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。
在本申请的一些具体示例中，如图1所示，洗衣机1包括箱体100、旋转桶组件200、 波轮300、接水盘400、驱动单元500和支撑减震组件600。
旋转桶210设于支撑盘502，波轮300可旋转地设在旋转桶210内。接水盘400设置于箱体100内且至少一部分位于旋转桶210的下方，接水盘400用于支撑旋转桶210，这里可以是直接支撑，也可以是间接支撑。
在本实施例中，驱动单元500安装在接水盘400上，例如安装在接水盘400的下表面，用于驱动旋转桶210和波轮300中的至少一个旋转。驱动单元500设有穿设接水盘400且与接水盘400连接配合的驱动轴组件501，接水盘400与旋转桶210之间设有与驱动轴组件501连接的支撑板，支撑板与旋转桶210固定连接。
排水通道240将由旋转桶210甩出的液体通过出水口211引导至接水盘400。其中，接水盘400内可以具有接水槽410且接水槽410的最低处设有排水口进行排水，接水盘400上也可以不设置排水口，而采用导管等引出接水槽410内的水。支撑减震组件600安装在箱体100内且与接水盘400相连。
由此，通过设置接水盘400，不仅可以盛接排水通道240内排出的液体，而且可以将驱动单元500和支撑减震组件600安装在接水盘400上，实现承载驱动单元500和支撑旋转桶210的作用。
进一步地，洗衣机1还包括用于保持旋转桶210旋转时平衡的平衡圈270，平衡圈270设在旋转桶210的上端且与旋转桶210的上端相连，导水罩220的上端邻近平衡圈270，且导水罩220的上端与平衡圈270间隔设置，该间隙可以便于导水罩220的安装，进水口221设于导水罩220的上端。这样，进水口221位于平衡圈270的下方，且与平衡圈270间隔一定距离，旋转桶210旋转时，便于旋转桶210内的水在离心力的作用下进入进水口221，从而进入排水通道240内。导水罩220的上端也可以与平衡圈270相连，这样，平衡圈270与导水罩220的上端限定出进水口221，旋转桶210旋转时，便于旋转桶210内的水在离心力的作用下进入进水口221，从而进入排水通道240内。
