进一步，所述洗涤桶的外侧设有自上向下导水的排水通道，所述排水通道的上端通过脱水口与洗涤桶内部连通，下端沿着洗涤桶的桶壁向下延伸至洗涤桶的底部，并在该端设有出水口，所述出水口位于挡水环围成的凹腔结构内。
进一步，所述排水通道的与洗涤桶相对一侧的内壁面由上向下逐渐向远离洗涤桶的方向偏离，使得所述出水口位于排水通道距离洗涤桶轴线的最远处。
进一步，所述排水通道包括水道壳体和部分洗涤桶壁，所述水道壳体扣合在洗涤桶壁上，水道壳体的上端延伸至洗涤桶的上端口处，下端延伸至洗涤桶的底部，并形成所述出水口。
进一步，所述脱水口形成在洗涤桶壁上；优选的，脱水口位于靠近洗涤桶上端口的洗涤桶壁上。
进一步，所述洗涤桶的底部设有一洗涤桶排水口，并安装有一控制该洗涤桶排水口打开或关闭的阀塞，在所述阀塞打开时，所述洗涤桶排水口排水进入挡水环围成的凹腔结构中。
进一步，所述挡水环的顶部高于排水通道的出水口，挡水环的内周壁与排水通道的外壁之间预留一定的空隙。
进一步，所述挡水环的上沿低于洗涤桶的上端，优选的，挡水环的高度低于洗涤桶的1/2高度。
进一步，所述洗涤桶的顶端设有一平衡环，所述脱水口设置在平衡环的下侧，平衡环的内径小于洗涤桶上端开口的内径，以阻挡洗涤桶中的水向上越过平衡环。

具体实施方式
下面结合附图对本发明的具体实施方式作进一步详细的描述。
如图1至图4所示，一种洗衣机，包括，箱体1、用于容纳被洗涤衣物的洗涤桶2，驱动洗涤桶2转动的动力装置3和安装在洗涤桶2下部的安装板4，以及连接安装板4与箱体1的减振部件。所述洗涤桶2可转动地设置在箱体1中，洗涤桶2支撑在安装板4上，并可相对安装板4转动，洗涤桶2作为盛水桶用于容纳洗涤水，安装板4用于支撑洗涤桶2，且安装板4通过减振部件与箱体1可活动地连接，在洗涤或脱水时，洗涤桶2和安装板4会产生振动，该振动传递至减振部件后被吸收。
所述安装板4上设有一挡水环11，所述挡水环11向洗涤桶2方向延伸，并围成一凹腔结构，凹腔结构用于汇集洗涤桶排出的洗涤水，凹腔结构的底部安装有排水管6向外排水。所述洗涤桶2的外侧设有自上向下导水的排水通道5，可以为一个或多个，所述排水通道5竖向设置，其上端通过脱水口8与洗涤桶2内部连通，下端沿着洗涤桶2的桶壁向下延伸至洗涤桶2的底部，并在该端设有出水口15，所述出水口15位于由挡 水环11围成的凹腔结构内，从出水口15流出的水将落入至凹腔结构内，并由排水管6排出至箱体1外部。
所述挡水环的上沿低于洗涤桶的上端。优选的，如图1所述，挡水环11的高度低于洗涤桶2的1/2高度。
所述排水通道5的与洗涤桶2相对一侧的内壁面由上向下逐渐向远离洗涤桶轴线的方向偏离，以使排水通道5内的水在离心力作用下向下流动，所述出水口15位于排水通道距离洗涤桶轴线的最远处。
所述洗涤桶2的内径由下向上逐渐增大，在洗涤桶2高速转动时，洗涤桶2中的洗涤水在离心力的作用下，将沿洗涤桶壁向上爬升，并在上升至一定高度后从脱水口8进入排水通道5内，然后沿排水通道5向下流动，从出水口15流出落入凹腔结构内，最终从洗衣机排水口排出。
具体地，所述排水通道5包括水道壳体12和部分洗涤桶壁，所述水道壳体12扣合在洗涤桶壁上，水道壳体12的上端延伸至洗涤桶2的上端口处，下端延伸至洗涤桶2的底部，并形成所述出水口15，所述脱水口8形成在洗涤桶壁上。
所述洗涤桶2的底部设有一洗涤桶排水口，该洗涤桶排水口排水的位置位于挡水环11围成的凹腔结构内，并安装有一控制该洗涤桶排水口打开或关闭的阀塞13，在所述阀塞13打开时，所述洗涤桶排水口与挡水环11围成的凹腔结构相连通。在洗涤阶段，阀塞13处于关闭状态，在脱水阶段，阀塞13处于打开状态，当阀塞13打开后，洗涤桶2中的洗涤水流入凹腔结构内，并由排水管6排至洗衣机外。
所述洗涤桶2的顶端设有平衡环7，所述脱水口8位于在平衡环7的下侧，为避免在脱水时，洗涤水从洗涤桶2中溢出，平衡环7的内径小于洗涤桶2上端开口的内径，以形成一台阶面阻挡洗涤桶2中的水向上越过平衡环7流出。具体地，所述洗涤桶2的上端设有一环形卡口卡在平衡环7底部的外侧，当洗涤桶2中的水向上流动至与平衡环7接触时，平衡环7的底部将阻挡水流继续向上流动，起到汇集水流进入脱水口8的作用。
优选地，所述挡水环11的顶部高于排水通道5的出水口15，挡水环11的内周壁与排水通道5的外壁之间预留一定的空隙，以避免在洗涤桶2转动时，产生碰撞。
优选地，所述洗涤桶2的内壁上设有用于与衣物接触摩擦的凸起或纹路，在洗衣过程中，可以起到与衣物摩擦的作用。
所述动力装置3安装在安装板4的底部，包括，电机和减速离合器，电机的转轴通过减速离合器与洗涤桶底连接，以驱动洗涤桶2旋转。所述减速离合器的输出轴穿过安装板4与洗涤桶2连接，在输出轴与安装板4之间设有至少一动密封。优选地，所述安装板4的底部设有多个向下凸起的加强筋。
在所述安装板4的上表面还设有一锁止结构14，所述锁止机构14位于洗涤桶2的底部，并与洗涤桶2配合，以限制洗涤桶2转动，所述锁止机构14可以锁住洗涤桶2，防止洗涤桶2转动，在洗涤阶段，锁止机构14锁住洗涤桶2，使其不能转动，在脱水阶段，锁止机构14解锁，使得洗涤桶2可以转动。
所述减振部件包括吊杆9和吊杆座10，所述吊杆9的上端与箱体1连接，下端与吊杆座10连接，所述安装板4的边缘上设有与吊杆座10配合的卡口，所述吊杆座10卡状在卡口内，并位于安装板4的下侧，吊杆座10内安装有弹簧，在安装板4和洗涤桶2重力作用下，吊杆座10内的弹簧被压缩，并在洗涤桶2振动时起到减振的功能。安装板4位于洗涤桶2的下部，使得吊杆座10位于洗涤桶2以下，不占用洗涤桶2与箱体1之间的空间，有利于扩大洗涤桶2的容积。
本发明的脱水过程为，首先，脱水前洗涤桶2内的水先通过洗涤桶2底部的洗涤桶排水口排出，然后电机驱动洗涤桶2高速旋转，剩余在洗涤桶2中的水在离心力的作用下，沿着洗涤桶壁向上爬升，并进入排水通道5内，在排水通道5内，水流改变流动方向，向下流动，并沿排水通道5流出洗涤桶2，落入挡水环11围成的凹腔结构内，最终通过排水管6排出洗衣机外。
