下面参考附图描述根据本发明实施例的洗衣机1。
如图1-图4所示，根据本发明实施例的洗衣机1包括箱体100、旋转桶210、平衡圈230和密封件232。
旋转桶210可旋转地设在箱体100内，旋转桶210的周壁构造有向旋转桶210的内部凸出的压筋212。平衡圈230设在旋转桶210的上端，平衡圈230上设有密封压槽231。密封件232设在密封压槽231内且被与压筋212相抵接。
根据本发明实施例的洗衣机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。
并且，旋转桶210的周壁构造有向旋转桶210的内部凸出的压筋212，平衡圈230设有密封压槽231，密封件232装在密封压槽231内，该密封压槽231通过密封件232与压筋212配合，装配时，压筋212与密封压槽231进行压合，使密封件232过盈紧配，从而可以避免脱水时水从旋转桶210的上部飞溅洒出而进入箱体100内损坏洗衣机1，提高旋转桶210的封闭效果，从真正意义上实现单桶结构。
下面参考附图描述根据本发明具体实施例的洗衣机1。
如图1-图4所示，根据本发明实施例的洗衣机1包括箱体100、旋转桶210、平衡圈230、密封件232、导水罩220和接水盘400。
旋转桶210可旋转地设在箱体100内，旋转桶210的周壁和/或底壁上设有出水口211，导水罩220设于旋转桶210的内周壁面，且导水罩220罩设出水口211，导水罩220设有进水口221，且导水罩220限定出与进水口221和出水口211连通的导水腔240。旋转桶210内因离心力作用而上升的液体通过进水口221进入至导水腔240内并通过出水口211排出。
具体而言，洗衣机1在脱水时，旋转桶210旋转，即导水罩220随旋转桶210旋转，旋转桶210内的液体在离心力的作用下向上移动，并由进水口221进入导水腔240，进入导水腔240的液体被导水罩220引导至出水口211，并由出水口211排出。
由此，通过进一步在旋转桶210的内周壁面上设置导水罩220，且在导水罩220上设置进水口221、在旋转桶210的周壁和/底壁设置出水口211，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进入导水罩220内，在导水罩220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，导水罩220连接在旋转桶210上，无需在箱体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。
出水口211可以设置在旋转桶210的周壁上，也可以设置在旋转桶210的底壁上，或者出水口211设置在周壁和底壁上。具体的，出水口211设置在旋转桶210的周壁上，这样导水罩220罩设出水口211，且导水罩220的下端仅与旋转桶210的周壁连接，利于导水罩220与旋转桶210的周壁的密封。当然，本发明中的出水口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。出水口211设置在周壁和底壁上，既利于导 水罩220与旋转桶210的周壁的密封，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。
因此，根据本发明实施例的洗衣机1具有容量大、节水和免污、成本低、脱水效果好、外观美观、利于密封等优点。
在本发明的一些具体实施例中，如图1-图4所示，压筋212设于旋转桶210的上部且由旋转桶210的周壁整体向内凸出而成。换言之，旋转桶210的周壁的上部的厚度不变，通过使旋转桶210的周壁的上部向旋转桶210的内部变形凸出，从而形成压筋212，由此压筋212的加工工艺简单。
具体而言，如图2和图4所示，平衡圈230的下表面设有压块233，密封压槽231设在压块233上，且密封压槽231位于压筋212上方，这样，通过在平衡圈230上设置压块233且将密封压槽231设置在压块233上，从而可以在不调整平衡圈230的安装位置的情况下，利用压块233将密封压槽231内的密封件232向下压紧在压筋212上，且保证具有足够的压紧力，以保证密封效果。
进一步地，如图2和图4所示，压块233设有向下延伸的限位筋234，限位筋234在旋转桶210的径向上位于压筋212的内侧，通过限位筋234和压筋212在旋转桶210的径向上的相互止挡，能够实现限位效果，提高平衡圈230与旋转桶210的相对位置的稳定性，且便于对准装配。
在本发明的一些具体示例中，如图1和图2所示，密封压槽231的下表面敞开，例如，密封压槽231大体呈倒U形，密封压槽231内的密封件232被压紧在压筋212的上表面，密封件232过盈紧配，与平衡圈230和旋转桶210之间均紧密配合，有效阻止旋转桶210内的水因离心力而上升从旋转桶210的顶部洒出。
在本发明的另一些具体示例中，如图3和图4所示，密封压槽231的下表面和朝向旋转桶210的内周壁面的表面敞开，密封压槽231内的密封件232被压紧在压筋212的上表面和旋转桶210的内周壁面。换言之，密封压槽231不仅下表面敞开，而且朝向旋转桶210的内周壁面的表面敞开，即密封压槽231的两个表面敞开，由于为了保证密封件232的过盈紧配，密封件232体积需要比密封压槽231的容积稍大，这样会导致密封件232的装配较困难，而通过将密封压槽231的两个表面敞开，可以在保证密封效果的情况下，方便装配。
进一步地，如图4所示，压筋212的上表面和旋转桶210的内周壁面之间为圆弧过渡，一方面提高旋转桶210的整体结构强度，另一方面消除压筋212的上表面和旋转桶210的内周壁面之间的死角，保证密封件232与压筋212的上表面和旋转桶210的内周壁面之间部分没有间隙，从而提高密封效果。
在本发明的一些具体实施例中，如图2和图4所示，压筋212沿旋转桶210的周向延伸呈环形，密封压槽231沿平衡圈230的周向延伸呈环形，密封件232为沿密封压槽231的周向延伸的密封圈，旋转桶210的周向各处均通过压筋212与密封压槽231共同压紧密封件232，进而能够在旋转桶210的周向上对旋转桶210的上端进行全面的密封，进一步提高旋转桶210的封闭效果。
在本发明的一些具体实施例中，如图1和图3所示，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。导水腔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。
由此，通过设置接水盘400，不仅可以盛接导水腔240内排出的液体，而且实现承载和支撑的作用。
进一步地，如图1和图3所示，导水罩220的上端邻近平衡圈230，且导水罩220的上端与平衡圈230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230的下方，且与平衡圈230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，从而进入导水腔240内。
在本发明的一些具体示例中，如图1和图3所示，旋转桶210的周壁与旋转桶210的中心轴线平行设置，导水罩220与旋转桶210的侧壁平行设置并沿上下方向延伸。换言之，旋转桶210的内直径在上下方向上处处相等，旋转桶210的外直径在上下方向上处处相等。这里需要理解地是，上述处处相等是指大体相等，不排除旋转桶210上设有一些凹凸结构。换言之，旋转桶210大体为圆柱体形。
在本发明的一些具体实施例中，如图1和图3所示，进水口221设在导水罩220的上部，出水口211设置在旋转桶210的周壁的下部。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，旋转桶210的下部是指，旋转桶210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的引导下流至旋转桶210下部的出水口211，从而进一步提高脱水效率和脱净效果。
进一步地，如图1和图3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设在旋转桶210的周壁且邻近旋转桶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与旋转桶210周壁的密封，且可以降低接水盘400的侧壁的高度，进 而节约用料、降低成本。
进一步地，如图1和图3所示，为了提高洗衣机1的排水效果，出水口211为多个，多个出水口211沿旋转桶210的周向等间隔设置，导水罩220为多个，多个导水罩220沿旋转桶210的周向间隔设置，每个导水罩220罩设至少一个相对应的出水口211。举例而言，出水口211为两个且在旋转桶210的径向上相对设置，导水罩220为两个且在旋转桶210的径向上相对设置，两个导水罩220分别一一对应地罩设两个出水口211。
如图1-图4所示，根据本发明实施例的洗衣机1包括箱体100、旋转桶210、平衡圈230、密封件232和波轮300。
旋转桶210可旋转地设在箱体100内，旋转桶210的周壁构造有向旋转桶210的内部凸出的压筋212。平衡圈230设在旋转桶210的上端，平衡圈230上设有密封压槽231。密封件232设在密封压槽231内且被压紧在压筋212上。波轮300可旋转地设在旋转桶210内。
根据本发明实施例的洗衣机1，采用单桶结构，从而提高容量、节水和免污、降低成本，而且旋转桶210的压筋212通过密封件232与平衡圈230上的密封压槽231配合，提高了旋转桶210的封闭效果，防止洗涤水从旋转桶210的上端飞溅洒出，真正意义上实现单桶结构。
根据本发明实施例的洗衣机1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。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示意性实施例”、“示例”、“具体示例”、或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
