进一步的，所述洗涤桶的顶端设有平衡环，所述集水环设于洗涤桶内部、平衡环的下侧。
进一步的，所述洗涤桶周壁内侧设有排水通道，所述排水通道与集水环相连通，将集水环内的水引导排出。
进一步的，所述排水通道竖向设置，其上端与集水环连通，下端与洗涤桶底部设有的排 水口连通，将集水环内的水引导至排水口排出；
优选地，所述排水口位于洗衣机波轮的下方，排水通道延伸至该排水口处。
进一步的，所述集水环内设有引导洗涤水变向进入排水通道的挡水板，所述挡水板位于排水通道进水口的上方，并与集水环所在的水平面呈一定角度倾斜设置。
进一步的，所述排水通道包括水道壳体和至少部分洗涤桶壁，所述水道壳体面向洗涤桶壁的一侧设有上下贯通的沟槽，水道壳体扣合在洗涤桶壁上，与洗涤桶壁共同围成水流通道；
优选地，所述水道壳体可拆卸地安装在洗涤桶上。
进一步的，所述集水环面向洗涤桶轴心的一侧为弧形面，该弧形面沿着洗涤桶轴向由下向上逐渐向洗涤桶中心方向弯曲；
优选地，集水环的脱水口设置在弧形面的底部起始端。
进一步的，所述洗涤桶具有一定的锥度，在洗涤桶高速转动时，洗涤桶中的洗涤水在离心力的作用下，沿洗涤桶壁向上爬升，并在上升至一定高度后从集水环的脱水口进入集水环内。
进一步的，还包括安装在洗涤桶下部用于支撑洗涤桶的安装板，所述安装板通过减振部件与箱体连接。
进一步的，所述安装板上设有一挡水环，所述挡水环向洗涤桶方向延伸，形成一容纳洗涤水的凹腔结构，凹腔结构的底部连有向洗衣机外排水的排水管；
优选地，所述挡水环的高度略高于洗涤桶底面，并与洗涤桶的外周壁之间预留一定的空隙。
采用本发明所述的技术方案后，带来以下有益效果：
本发明的洗衣机省去了外桶结构，洗衣机洗涤桶直接作为盛水桶，可以提高洗涤水的利用率，并降低洗涤水的使用量，同时，省去外桶后，洗涤桶的体积可以设置的更大，可以洗涤的衣物量随之增加，达到了洗衣机扩容的目的，另一方面，本发明的排水通道位于洗涤桶内侧，在洗衣机脱水时不会直接与箱体碰撞，洗衣机脱水时的噪音更低，使用寿命更长。

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和图2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坐落在安装板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。
所述洗涤桶2的顶端设有平衡环7，平衡环7的下侧设有集水环8，在洗涤桶2周壁内侧设有排水通道5，所述集水环8与排水通道5相连通，在集水环8朝向洗涤桶2一侧设有脱水口，所述排水通道5竖向设置，其上端与集水环8连通，下端与洗涤桶底部设有的排水口连通。洗涤桶2具有一定的锥度，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集水环8的脱水口进入集水环8内，洗涤水在集水环8内环形流动，当洗涤桶2转速降低时，洗涤水将沿排水通道5向下流动，并最终从洗衣机排水口排出。
结合图3和图4所示，优选地，所述集水环8内设有引导洗涤水进入排水通道5的挡水板13，所述挡水板13位于排水通道5进水口的上方，并与水平面呈一定角度倾斜设置。当洗涤水在集水环8内环形流动时，将碰撞在挡水板13上，挡水板13正对水流方向的一侧向下倾斜设置，使水流撞击到挡水板13后改变流向，由沿桶周向流动，变为沿桶壁向下流动，并进入排水通道5。由于挡水板13改变了集水环8内的水流流向，因此，在高速脱水时，可以使集水环8内的水流入至排水通道5内，避免集水环8内的水量过多。
所述安装板4上设有一挡水环12，挡水环12由安装板4的上表面向洗涤桶2方向凸起， 并延伸一定高度，形成容纳洗涤水的凹腔结构，凹腔结构的底部设有开口并连有排水管6，通过排水管6与洗衣机排水口连通，所述洗涤桶2底部的排水口安装有一阀塞15，所述阀塞15位于挡水环12的内侧，在洗涤阶段，阀塞15处于关闭状态，在脱水阶段，阀塞15处于打开状态，当阀塞15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。
优选地，挡水环12的高度略高于洗涤桶2底面，并与洗涤桶2的外周壁之间预留一较大的空隙，以避免在洗涤桶2转动时，产生碰撞。
所述排水通道5的下端与洗涤桶2底部的排水口连接，该排水口位于洗衣机波轮的下方，排水通道5延伸至该排水口处，排水通道5包括水道壳体11和部分洗涤桶壁，所述水道壳体11面向洗涤桶壁的一侧设有上下贯通的沟槽，水道壳体11扣合在洗涤桶壁上，与洗涤桶壁共同围成水流通道。水道壳体11与现有洗衣机内桶中的水道结构相似，区别在于水道壳体11上端延伸至与集水环8连接，且水道壳体11面向洗涤桶2轴线的一侧不具有出水口。
水道壳体11上可以设置多条并排的沟槽，形成多条水流通道。
优选地，水道壳体11可拆卸地安装在洗涤桶2上，所述水道壳体11的底部设有卡钩，所述洗涤桶2的桶壁上设有与所述卡钩配合的卡口，水道壳体11的上部设有螺钉孔，并通过螺钉与洗涤桶2固定连接。在安装水道壳体11时，先将卡钩可在卡口上，对水道壳体11进行定位和支撑，然后通过螺钉将水道壳体11固定在洗涤桶2上。
优选地，所述水道壳体11面向洗涤桶轴线的一侧设有用于与衣物接触摩擦的凸起或纹路，在洗衣过程中，水道壳体11面向洗涤桶轴线的表面可以起到与衣物摩擦的作用。
为避免在脱水时，洗涤水从洗涤桶2中溢出，所述集水环8面向洗涤桶轴心的一侧为弧形面，该弧形面沿着洗涤桶轴向由下向上逐渐向洗涤桶2中心方向弯曲，使得洗涤桶2上端的开口逐渐缩小，集水环8的脱水口设置在弧形面的底部起始端，当洗涤水沿桶壁向上爬升时，集水环8的弧形面起到了阻挡水流继续向上爬升的作用，并汇集水流进入集水环8的脱水口。
所述动力装置安装在安装板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，并进入集水环8内，在集水环8内，水流受到挡水板13的作用，改变流动方向，向下流入排水通道5内，并沿排水通道5流出洗涤桶2，落入挡水环12围成的凹腔结构内，最终通过与排水管6排出洗衣机外。
以上所述为本发明的实施方式，应当指出，对于本领域的普通技术人员而言，在不脱离本发明原理前提下，还可以做出多种变形和改进，这也应该视为本发明的保护范围。
