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3所示，根据本发明实施例的洗衣机1包括桶部装200和减震器600。
桶部装200包括旋转桶210、波轮300、接水盘400和驱动单元500。波轮300可旋转设置在旋转桶210内。接水盘400的至少一部分位于旋转桶210的下方。驱动单元500用于驱动旋转桶210和波轮300中的至少一个，驱动单元500安装在接水盘400上。减震器600安装在接水盘400上。
其中，桶部装200的空载重心位置与桶部装200的最低点之间的高度为hg1，桶部装200的满载重心位置与桶部装200的最低点之间的高度为hg2，减震器600和接水盘400的安装位置与桶部装200的最低点之间的高度为hz且满足：hg1≤hz≤hg2。
具体而言，在三维坐标内，接水盘400的质量为m1、重心坐标为(x1,y1,z1),旋转桶210的质量为m2、重心坐标为(x2,y2,z2),驱动单元500的质量为m3、重心坐标为(x3,y3,z3),其它零件的质量为mi、重心坐标为(xi,yi,zi)，这里可以理解地是，其它零件是指，桶部装200中除旋转桶210、波轮300、接水盘400和驱动单元500之外的零件。桶部装200的空载总质量为Ma＝m1+m2+m3+…+mi，水和负载总质量为Mb、重心坐标为(Xb,Yb,Zb)，桶部装200的底部坐标为Z0。
桶部装200的空载重心位置(X1,Y1,Z1)
X1＝(m1*x1+m2*x2+m3*x3+…+mi*xi)/Ma,
Y1＝(m1*y1+m2*y2+m3*y3+…+mi*yi)/Ma,
Z1＝(m1*z1+m2*z2+m3*z3+…+mi*zi)/Ma，
hg1＝Z1-Z0。
桶部装200的满载重心位置(X2,Y2,Z2)
X2＝(Ma*X1+Mb*Xb)/(Ma+Mb),
Y2＝(Ma*Y1+Mb*Yb)/(Ma+Mb),
Z2＝(Ma*Z1+Mb*Zb)/(Ma+Mb)，
hg2＝Z2-Z0。
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，采用减震器600安装在接水盘400，能够大幅提高对接水盘400的约束，减小桶部装200的振动，并进一步优化减震器600与接水盘400的安装位置，从而进一步减小桶部装200的振动幅度，使整机达到更优的减震效果，进而可以减小桶部装200与洗衣机箱体之间的间隙，从而可以通过增加旋转桶210的直径和高度来增大容量。
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3所示，根据本发明实施例的洗衣机1包括桶部装200和减震器600。
具体而言，如图1和图2所示，减震器600安装在接水盘400的侧壁上，通过约束接水盘400来约束整个桶部装200，以减小桶部装200的振动。例如，接水盘400的外侧壁面设有安装架420，减震器600安装在安装架420上，从而方便减震器600与接水盘400的安装。
在本发明的一些具体实施例中，如图1所示，洗衣机1还包括底座700。
底座700位于接水盘400的下方，减震器600的上端安装在接水盘400上，且减震器600的下端安装在底座700上。由此，采用减震器600将接水盘400连接到底座700，该方式对桶部装200的约束较强，洗衣机1脱水时桶部装200因内部负载偏心会产生振动，但通过减震器600减振后会大幅减小，从而进一步减小桶部装200的振动。
可选地，如图3所示，减震器600包括下连接器610、上连接器620和减震弹性件630。下连接器610安装在底座700上。上连接器620安装在接水盘400上，且上连接器620与下连接器610可伸缩的相连。减震弹性件630分别与上连接器620和下连接器610相连。上连接器620和下连接器610通过相互之间的位移以及减震弹性件630的弹力实现对桶部装200的支撑和减震作用。
具体而言，如图3所示，减震弹性件630为弹簧，减震弹性件630套设在上连接器620上，且减震弹性件630的两端分别与上连接器620和下连接器610相连。
在本发明的一些具体示例中，如图1所示，为了进一步提高对桶部装200的约束，从而进一步减小桶部装200的振动，减震器600为多个且沿接水盘400的周向等间隔布置。举例而言，减震器600为四个，接水盘400的外周壁面设有沿其周向等间距设置的四个安装架420，四个减震器600的下端分布在底座700的四个拐角处，四个减震器600的上端安装在接水盘400的四个安装架420上，每个减震器600与接水盘400的安装位置满足：hg1≤hz≤hg2。
在本发明的一些具体实施例中，如图1和图2所示，旋转桶210的周壁和/底壁设有出水口211，桶部装200还包括导水罩220。
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排出至接水盘400。
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排出至接水盘400。
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。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。
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。
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。
由此，接水盘400不仅起到承载驱动单元500和支撑旋转桶210的作用，而且可以盛接导水腔240内排出的液体。
进一步地，如图1和图2所示，接水盘400的侧周壁向上延伸且高于出水口211，以使导水腔240内的液体从出水口211排出后全部流入接水盘400，避免水在旋转桶210的下端飞溅洒出。
在本发明的一些具体示例中，如图1和图2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2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2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2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3所示，根据本发明实施例的洗衣机1包括桶部装200、底座700和减震器600。
桶部装200包括旋转桶210、波轮300、接水盘400和驱动单元500。波轮300可旋转设置在旋转桶210内。接水盘400的至少一部分位于旋转桶210的下方。驱动单元500用于驱动旋转桶210和波轮300中的至少一个，驱动单元500安装在接水盘400上。底座700位于接水盘400的下方。减震器600的上端安装在接水盘400上，且减震器600的下端安装在底座700上。
其中，桶部装200的空载重心位置与桶部装200的最低点之间的高度为hg1，桶部装200的满载重心位置与桶部装200的最低点之间的高度为hg2，减震器600和接水盘400的安装位置与桶部装200的最低点之间的高度为hz且满足：hg1≤hz≤hg2。
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，并且采用安装在接水盘400上的减震器600，并限定减震器600与接水盘400的安装位置，能够实现更好的减震效果。
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。
