Description

洗涤设备排水通道及洗涤设备 技术领域
本发明属于家用电器领域，具体地说，涉及一种洗涤设备排水通道及洗涤设备。
背景技术
传统的全自动波轮洗衣机一般包括内桶、外桶、减振部件和动力系统组成，在洗衣和脱水时，内桶相对外桶转动，使衣物与洗涤水产生作用，达到洗净衣物或脱水的目的，其中，外桶安装在内桶的外部，为内桶提供支撑，外桶作为盛水桶，内桶侧壁上均布着排水孔，使内外两桶相通。在洗衣的过程中，衣物放置在内桶中，两桶水位一样高，但外桶不与衣物接触，现有洗衣机的外桶相对内桶的体积较大，造成内外桶之间的洗涤水存量较多，两桶之间的洗涤液不能充分利用，既增加了洗衣的用水量，又降低了洗涤时洗涤液的浓度，而且也造成洗衣机整体的体积偏大。另外，使用一段时间后，外桶内壁和内桶外壁上会附着污垢，甚至会发霉，进而会污染所洗涤的衣物，且桶壁很难清洁。
针对该情况，有些厂商做出了改进，为了节省水资源，洗衣机越来越多的采用无孔内桶的方式，使内外桶分离，只用内桶储水，而外桶无水。在内桶侧壁靠上端开设有排水孔，这样，当洗衣机脱水时，水由于离心力的作用被甩在内桶内壁上，并沿内桶内壁向上移动，从内桶上端的排水孔排出，这样提高了洗衣机节水的效果，并节约了洗涤剂的用量。
但是，在上述方案中存在以下问题，由于洗衣机脱水时高速旋转，衣物中的水通过内桶侧壁上的排水孔甩出，直接打在外桶侧壁上，容易四处飞溅，外桶内壁上长期有水，还是容易滋生细菌，不利于环保。
另外，为了增加洗衣机的洗涤容量，需要更大的内桶，即需要增加内桶的高度或直径。如果内桶具有更大的尺寸，则容纳内桶的外桶及机壳也需要随着内桶的增大而增大。
洗衣机机壳的增大受到安装洗衣机的区域空间的限制，一般的用户家中用于放置洗衣机的位置有限，增加洗衣机机壳来达到增加洗衣桶容量的目的不够现实，如何在不增加洗衣机的机壳的前提下，增加内桶的容量成为困扰设计者的一大难题。
申请号为CN99230455.5的中国专利公开了一种单桶式的节水型洗衣机，洗涤桶的桶口处设有一集水装置，集水装置的集水口沿洗涤桶围罩在其的桶口处，集水装置位于桶口处的集水腔与若干排水管相连，它们沿洗涤桶的外壁自上而下对称布置，甩干时，集水装置收集因 高速旋转的离心水流并将其向下引导排掉，该结构虽然省去了外桶，但在其洗涤桶转动时，尤其在高速脱水时，由于排水管凸出于洗涤桶外壁，当洗涤桶转动时，凸出的排水管会构成一定的风阻，不仅产生较大的噪音，还会影响洗涤桶的转动平衡。
有鉴于此特提出本发明。

图1为本发明洗涤桶结构示意图，主要显示本发明排水通道安装在洗涤桶外周壁的示意图；图2为本发明洗涤桶的剖视图，主要显示本发明排水通道的延伸变化结构；图3是本发明洗涤桶的俯视图，主要显示排水通道的外表面为光滑过渡的曲面造型；图4和图5是本发明图3中的A部不同结构的放大视图，主要显示排水通道与洗涤桶的装配方式。
如图1至图5所示，本发明所述的洗涤设备排水通道，安装于洗涤设备的洗涤桶1上，自上向下将洗涤桶内的水引导至洗涤桶外部，排水通道2包括壳体3和内部的排水腔室4，壳体3配置有随洗涤桶1转动降风阻的表面结构。
进一步该降风阻的表面结构，具体可体现为，壳体3对应洗涤桶1转动方向的迎风表面具有光滑的曲面或平面过渡结构。
或者，体现在，壳体3凸出于洗涤桶周壁10的表面与洗涤桶周壁10平滑过渡连接。
实施例一
如图3至图5所示，本发明所述的壳体3包括，
迎风面31，对应洗涤桶1转动方向迎风的一侧表面；
背风面32，与迎风面31相对的另一侧表面；
引水面33，位于迎风面31和背风面32之间，远离洗涤桶周壁10的一侧表面；
迎风面31与洗涤桶周壁10平滑过渡连接；

还优选的，该锐角α不大于75°，更优选的，锐角α不大于45°。
当然，关于上述迎风面31与背风面32的限定是相对于洗涤桶1转动的方向而言，其并不是绝对固定的，迎风面31和背风面32是可互相转换的，背风面32和迎风面31的设计结构可相同或等同。
实施例二
本实施例在实施例一的基础上，进一步限定为，所述的迎风面31与引水面33之间光滑过渡连接。该结构能够将迎风面的风快速引导至引水面外部，避免形成尖锐的噪音。
具体的，所述的迎风面31与引水面33之间圆角倒角，迎风面31与引水面33之间的夹角β为钝角，还优选的，该钝角β不小于100°，更优选的，钝角β不小于120°。
实施例三
如图4和图5所示，本实施例所述的迎风面31具有一光滑的曲面结构，至少包括一段向排水通道内部方向凹的曲面310。该结构不仅能够优化迎风面31与洗涤桶周壁10的平滑过渡连接，也能够优化迎风面31与引水面33之间光滑过渡连接，使得风阻进一步降低。
实施例四
如图4和图5所示，本实施例所述的引水面33具有一弧形曲面330，优选的，该弧形曲面330与洗涤桶周壁10在同一径向上的点的切线平行。即，引水面的弧形曲面330与洗涤桶周壁10同一径向的部分表面平行，引水面的弧形曲面330与洗涤桶周壁10同心设置。
实施例五
本实施例所述迎风面31与引水面33具有同一半径的弧形曲面结构，或者，迎风面31、引水面33及背风面32具有同一半径的弧形曲面结构。
实施例六
本实施例与上述的区别在于，所述的排水通道2对应垂直于洗涤桶1轴向的截面形状为梯形，包括近似梯形；
优选的，排水通道对应垂直于洗涤桶轴向的截面形状为等腰梯形。
实施例七
如图2所示，本发明所述的一种洗涤设备，包括可旋转的洗涤桶1，该洗涤桶1为盛水桶，洗涤桶周壁10上安装有上述的排水通道2。
进一步的，所述排水通道2为一独立的结构(参阅图4)，包括设于壳体上端的入水口21和设于壳体下端的出水口22，壳体3内具有从入水口21至出水口22的排水腔室4；
或者，所述排水通道的壳体3罩设在洗涤桶的周壁10上(参阅图5)，与洗涤桶周壁10配合形成向下导水的排水腔室4，上端与洗涤桶1内部连通。
进一步的，所述排水通道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，排水通道2的出水端具有与洗涤桶脱水转动方向相反一侧设置的出水口，进一步的保证了洗涤水可以快速从排水通道中排出，优化了整体结构。
实施例八，
本实施例所述排水通道2还包括与洗涤桶周壁外侧紧密贴合的第一排水部23；
与第一排水部23的出水端连通继续向下延伸的第二排水部24；
第二排水部24将洗涤水引导至洗涤桶1的下部。
进一步地，所述第一排水部23自上向下延伸至洗涤桶桶底所在水平面的位置；
所述第二排水部24自洗涤桶桶底所在水平面的位置继续向下并向洗涤桶中心轴线的方向倾斜延伸。
优选的，所述第一排水部23与第二排水部24平滑过渡连接。
进一步地，所述第一排水部23的外壁沿洗涤桶周壁10自上向下方向，距离洗涤桶中心轴线的距离呈逐渐变化的趋势；
所述第二排水部24的外壁自上向下方向，距离洗涤桶中心轴线的距离呈逐渐变化的趋势，该趋势与第一排水部的外壁变化趋势相反；
优选地，
第一排水部23距离洗涤桶中心轴线的距离呈递增趋势变化；
第二排水部24距离洗涤桶中心轴线的距离呈递减趋势变化。
进一步地，第二排水部下部出水端与洗涤桶中心轴线的距离小于洗涤桶桶底半径。
实施例九
如图1所示，本发明洗涤设备包括在洗涤桶1底部设置收集通过排水通道2引导排放的洗涤水的接水装置5，在接水装置5底部设置有用于排放洗涤水的排水结构，例如排水管。
本发明所述接水装置5为上部具有开口的凹腔结构，接水装置5的上部开口不高于洗涤桶周壁10上的排水通道2的上端。
在一个实施例中，将接水装置5的上部开口设置低于排水通道2上端的高度，避免接水装置5内的水过多时，回流至洗涤桶1内。
在一个实施例中，接水装置5位于洗涤桶1的下方，同时将接水装置5的轴线与洗涤桶1的轴线共线设置。
进一步地，如图1所示，本发明在接水装置5的底部设置有下凹的集水槽，集水槽沿接水装置5的底壁周向环绕设置，用于收集从排水通道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排水通道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
排水通道2的第二排水部24将洗涤桶1内的洗涤水导入至集水槽内；
优选地，集水槽的上沿高于第二排水部24的出水端所在位置的高度；
更优选地，集水槽的上沿不高于洗涤桶1自下向上一半的高度。
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。
