图1为本发明洗涤桶1结构第一示意图，主要显示本发明导水结构2的正面视图；图2为本发明导水结构2的剖视图，主要显示本发明导水结构2的内部结构；图3是本发明导水结构2的俯视图，主要显示导水结构2的外壁201呈大圆弧状造型；图4是本发明洗涤桶1结构的另一张示意图，主要显示洗涤桶1的整体结构；图5是本发明洗涤桶1结构的A部放大视图。
如图1至图5所示，本发明所述一种洗衣机的洗涤桶1，包括洗涤桶1本体，在洗涤桶1的桶壁上设置有脱水口3，所述脱水口3被配置为将洗涤桶1内部洗涤水导出的开口结构；对应脱水口3设置有将洗涤桶1内的洗涤水导出至洗涤桶1下部接水装置6的导水结构2，所述导水结构2设置于洗涤桶1的外壁并与脱水口3连通，由于洗衣机扩容，脱水阶段水从水道口排出，进入水道，本发明将洗涤桶1的脱水口3置于洗涤桶1桶壁，同时设置导水结构2与脱水口3连通，有效地利用了洗涤桶1脱水时水流的流动趋势，保证功能的同时，降低了能耗。
图1至图3所示为本发明所述的导水结构2示意图，没有外桶后，从水道内排出的水进入底部的排水槽内，扩容需求，排水槽的高度有限，且排水槽内的水位是有一定高度的，在内桶高速转动脱水时，水道的造型结构直接影响到溅水的程度，因此，本发明将导水结构2主要包括在距离洗涤桶1的远端设置有一弧形的外壁201和距离洗涤桶1近端设置的内壁202，内壁202靠近洗涤桶一侧，弧形外壁201的半径小于内壁202的半径设置，外壁201的半径小于内壁202的半径，即洗涤桶1的半径，将导水结构2的外壁201设置为大圆弧造型，减小脱水时和水的接触面积，保证洗涤水可以更快速的从导水结构2排出。
一种洗衣机的导水结构，所述
导水结构2的出水端横截面的面积大于入水端横截面的面积；
优选地，导水结构2的出水端沿洗涤桶1转动方向展开；
更优选地，所述导水结构2的出水端为敞开式结构；
再优选地，所述导水结构2的出水端为喇叭口状的结构。
进一步地，当洗涤桶1进行脱水作业时，为了更好的保证导水结构2内的洗涤水可以更好的被排至洗涤桶1下部的接水装置6，本发明将导水结构2的出水端设置成敞口状或者喇叭口状的结构，无论洗涤桶1正转或者反转脱水，均可以有效的保证洗涤水的高效排出，即所述导水结构2的出水端横截面的面积大于入水端横截面的面积；优选地，导水结构2的出水端沿洗涤桶1转动方向展开，出水端敞口结构的设计，进一步的保证了洗涤水可以快速从导水结构2中排出，优化了整体结构。
如图1和图4所示，本发明所述洗衣机的洗涤桶1结构中，洗涤桶1在脱水或者洗涤的工作过程中，被配置为用于盛放洗涤水的桶体结构，进一步地，本发明所述的桶体结构的桶壁位于脱水口3以外的部分呈封闭设置，这样设置省去了外桶的结构，将内桶作为盛放衣物和洗涤水的主体，在整体洗衣机体积不变或者变化很小的情况下，增加了洗涤桶1的容量，实现了洗衣机的扩容效果，由于以往的洗衣机需要设置外桶，并通过外桶与内桶的配合使用才能完成相应的洗涤和脱水工作，因此，会存在外桶与内桶之间会残留有污渍的情况，长期使用对健康非常不利，本发明所述的洗涤桶1的洗涤过程中水只存在洗涤桶1内，避免了传统洗衣机内外桶之间存水导致外桶内壁202和洗涤桶1外壁“藏污纳垢”的问题，具有更好的洗涤效果，同时，取消外桶，洗涤桶1为盛水桶，在洗涤过程中内外桶之间不再存水，减少了洗涤用水量，节约了洗涤用水量。
进一步地，如图1和图4所示，本发明将导水结构2嵌入洗涤桶1的外壁，并且作为一个独立的导水结构2，在其内部设置于洗涤桶1各自独立的导水腔室，独立腔室的导水结构2提高了洗涤桶1的使用寿命、同时也便于维护和更换，作为优选地，导水结构2与洗涤桶1的外壁形成光滑过度曲面，当洗涤桶1高速旋转时，光滑过渡的曲面可以有效降低风的阻力，降低能耗，提高洗涤效率。
如图2和图4所示，为了进一步保证排水的效果，本发明所述导水结构2还包括与洗涤桶1桶壁外侧紧密贴合的第一导水部4；与第一导水部4的出水端连通的第二导水部5；第二导水部5将洗涤水引导至洗涤桶1下部的接水装置6，由于脱水作业中洗涤桶1处于高速旋转的状态，因此，为了避免洗涤水在高速旋转的洗涤桶1状态下，从导水结构2中倒流回洗涤桶1中，因此，本发明将第一导水部4的外壁201设置成自洗涤桶1顶部朝向底部方向，距离洗涤桶1轴线的距离呈逐渐变化的趋势，并且将第二导水部5的外壁201设置成自洗涤 桶1顶部朝向底部方向，距离洗涤桶1轴线的距离呈逐渐变化的趋势；作为更优选地，第一导水部4距离洗涤桶1轴线的距离呈递增趋势变化；第二导水部5距离洗涤桶1轴线的距离呈递减趋势变化，本发明设置多段式的导水结构2利用了水在高速旋转洗涤桶1中的流动趋势，避免了在排水的过程中水流逆流，同时在排出的过程中保证水流的集中排出。
在一个实施例中，一种洗衣机，安装有上述所述洗衣机的洗涤桶1，包括配置为洗衣机主体的壳体12，在壳体12内配置有上述洗衣机的洗涤桶1，平衡环11，设置于洗涤桶1的顶部，同时在洗涤桶1的底部设置有，收集通过导水结构2引导排放的洗涤水的接水装置6，在接水装置6上设置有用于排放洗涤水的排水通道7，所述洗涤桶1还设置有排水口，用于排出洗涤桶1内部的多余水，排水通道7设置于靠近洗涤桶1排水口的位置，为了便于将接水装置6内洗涤水排出的同时，也将洗涤桶1内部多余的水排出。
如图4所示，本发明所述接水装置6为上部具有开口的凹腔结构，接水装置6的上部开口不高于洗涤桶1的脱水口3。
在一个实施例中，将接水装置6的上部开口设置低于洗涤桶1的脱水口3，避免接水装置6内的水过多时，从脱水口3回流至洗涤桶1。
在一个实施例中，接水装置6位于洗涤桶1的下方，同时将接水装置6的轴线与洗涤桶1的轴线共线设置。
进一步地，如图4所示，本发明在接水装置6的底部设置有下凹的集水槽8，集水槽8沿接水装置6的底壁周向环绕设置，用于收集从导水结构2导出的洗涤水，集水装置的集水腔的底壁设置用于引导水流至排水口的导水结构2，更好的导水排水，确保集水装置的集水排水，防止其积水溢流。
更进一步地，所述
导水结构2的第二导水部5将洗涤桶1内的洗涤水导入至集水槽8内；
优选地，集水槽8的上沿高于第二导水部5的出水端所在位置的高度；
更优选地，集水槽8的上沿不高于洗涤桶1自下向上一半的高度。
同时，在洗衣机洗涤作业时，为了保证洗衣机的正常工作，在洗涤桶1底部外侧的集水装置设置有锁止结构10，在洗涤时锁止结构10弹出，与洗涤桶1底部法兰盘上的定位结合，实现洗涤桶1的锁止；此外，为了避免在洗涤过程中，洗衣机洗涤水的流失，对应洗涤桶1桶底的排水口设置有阀塞13，洗衣机洗涤作业时，阀塞13与洗涤桶1底部的排水孔配合， 将排水孔堵住，防止洗涤桶1中的洗涤水溢出。
在一个实施例中，在具备上述所述的洗涤桶和洗衣机后，本实施例所述一种洗衣机的洗涤桶1，在洗涤桶1外壁设置有导水结构，连接导水结构、在洗涤桶1桶壁顶部设置有脱水口3，本实施例在导水结构2与洗涤桶1的连接处设置有连接结构，具体来说，导水结构2与洗涤桶1通过螺纹进行连接，在使用的过程中，如果遇到导水结构2破裂、堵塞等问题，用户或者维修人员可以将其拆卸下来进行维修。
如图1所示，本实施例所述的连接结构均匀分布于导水结构2两侧的通孔结构，螺栓可以通过通孔将导水结构2与洗涤桶1进行连接，本实施例所述螺纹连接仅仅是一种优选的实施例，本领域技术人员可以将其理解为本领域常用的其他技术手段，例如卡接、插接等。
在此处所提供的说明书中，说明了大量具体细节。然而，能够理解，本发明的实施例可以在没有这些具体细节的情况下实践。在一些实例中，并未详细示出公知的方法、结构和技术，以便不模糊对本说明书的理解。

除了这样的特征和/或过程或者单元中的至少一些是相互排斥之外，可以采用任何组合对本说明书(包括伴随的权利要求、摘要和附图)中公开的所有特征以及如此公开的任何方法或者设备的所有过程或单元进行组合。除非另外明确陈述，本说明书(包括伴随的权利要求、摘要和附图)中公开的每个特征可以由提供相同、等同或相似目的的替代特征来代替。
此外，本领域的技术人员能够理解，尽管在此所述的一些实施例包括其它实施例中所包括的某些特征而不是其它特征，但是不同实施例的特征的组合意味着处于本发明的范围之内并且形成不同的实施例。例如，在下面的权利要求书中，所要求保护的实施例的任意之一都可以以任意的组合方式来使用。
应该注意的是上述实施例对本发明进行说明而不是对本发明进行限制，并且本领域技术 人员在不脱离所附权利要求的范围的情况下可设计出替换实施例。在权利要求中，不应将位于括号之间的任何参考符号构造成对权利要求的限制。单词“包含”不排除存在未列在权利要求中的元件或步骤。位于元件之前的单词“一”或“一个”不排除存在多个这样的元件。列举了若干装置的单元权利要求中，这些装置中的若干个可以是通过同一个硬件项来具体体现。单词第一、第二、以及第三等的使用不表示任何顺序。可将这些单词解释为名称。
以上所述仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，虽然本发明已以较佳实施例揭露如上，然而并非用以限定本发明，任何熟悉本专利的技术人员在不脱离本发明技术方案范围内，当可利用上述提示的技术内容作出些许更动或修饰为等同变化的等效实施例，但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明方案的范围内。
