Description

洗衣机 技术领域
本发明属于洗涤设备技术领域，具体地说，涉及一种洗衣机。
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，但在其洗衣机脱水时，由于洗涤水都先进入集水装置，集水装置为一环形结构，内部填充的洗涤水向下排水速度不同，破坏洗涤桶高速旋转的平衡；另外，洗涤水进入集水装置后引导至洗涤桶下部向中心汇集排出，不利于排水，使得在离心力的作用下集中在集水腔内难以排出，造成洗涤水集中在洗涤桶的上端，增大洗涤桶上部的重量，更进一步破坏平衡，尤其是洗涤桶残余的水较多时，大部分洗涤水集中在集水腔内不被排出，提高洗涤桶和外桶的总体重心，产生了极大的震动噪音，也增大了脱水电机的工作载荷，易于损坏电机；最后，集水装置设置在洗涤桶上部，而洗涤桶脱水转动时，上部偏心的径向位移最大，为了避免集水装置碰撞洗衣机箱体，必须满足集水装置与箱体之间的安全距离，并不能真正达到扩容的目的。
有鉴于此特提出本发明。
发明内容

优选的，构成集水腔的周壁上沿高于出水口所在位置的高度。
更优选的，集水腔的周壁上沿不高于第一排水口所在位置的高度。
进一步的，所述集水腔内设有一下凹的环形凹槽，环形凹槽向下延伸低于集水腔底壁所在的高度，排水通道的出水口设于环形凹槽内。
进一步的，所述环形凹槽的深度沿周向由高到低变化设置，至少一第二排水口设于环形凹槽的最低处。
优选的，环形凹槽的深度沿与洗涤桶脱水时转向相同的方向由高到低变化设置。
进一步的，所述洗涤桶周壁高于第一排水口的上方为密封结构，洗涤桶内部通过周壁下部的第一排水口与外部相通。
进一步的，所述洗涤桶的内周壁还设有自上向下引导水排出的导水通道，导水通道下部罩设所述第一排水口，上部设有进水口且限定出与进水口和第一排水口连通的导水腔室，导水腔室通过进水口与洗涤桶内部相通。

采用上述技术方案后，本发明与现有技术相比具有以下有益效果。
本发明的洗衣机洗涤桶可用于在洗涤过程中盛水，因此洗涤桶采用“无孔内桶”的结构，同时取消外桶的设计，采用接水装置代替外桶接水排水，这使得本发明具有如下技术效果：
1、在洗衣机箱体容积不变的情况下可增加洗涤桶容量，实现洗衣机的扩容效果；
2、洗涤过程中水只存在洗涤桶内，避免了传统洗衣机内外桶之间存水导致外桶内壁和洗涤桶外壁“藏污纳垢”的问题，具有更好的洗涤效果；
3、取消外桶，洗涤桶为盛水桶，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；
4、利用洗涤桶内部自上向下的导水通道从洗涤桶周壁下部位置的第一排水口排出，能够避免现有技术中安装在洗涤桶外周壁上部的导水结构占用洗涤桶和箱体之间的空间，获得真正的扩容效果；
5、导水通道的进水口设置在与洗涤桶脱水转动方向一致的径向侧壁上，反向的径向侧壁密封，脱水时，洗涤水更易沿洗涤桶周向进入导水通道，提高排水速率；
6、在洗涤桶外周壁下部安装排水通道，将第一排水口出水向下引导，既能避免接水装置向上延伸，实现扩容效果，也能引导排水至接水装置的集水腔内，提高排水速度，并获得防止溅水的效果；
7、接水装置的集水腔的底壁设置用于引导水流至排水口的环形凹槽结构，更好的导水排水，并确保排水通道出水溅水的同时，更好的实现集水排水，防止其积水溢流。
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。

实施例一
如图1至图4所示，本实施例的一种洗衣机，包括箱体100、可转动地设在箱体内的洗涤桶200，还包括排水通道300，洗涤桶200周壁的下部位置设有第一排水口201，排水通道300设于洗涤桶200的外周壁上，与第一排水口201相通，将洗涤桶200排出的水导向洗涤桶的下方。
本实施例所述排水通道300的上部设有入水口301，下部设有出水口302，排水通道300密封罩在洗涤桶周壁第一排水口201上，入水口301与第一排水口201相通。
优选的，所述第一排水口201为至少一个，所述排水通道300为至少一个，每个排水通道300与至少一个第一排水口201相对应。
进一步的，所述第一排水口201为至少两个且沿洗涤桶200的周向间隔设置，所述排通道300为至少两个且沿洗涤桶200的周向间隔设置。
实施例二
如图4所示，本实施例所述排水通道300为一独立的结构，包括壳体303、设于壳体303一端的入水口301和设于壳体另一端的出水口302，入水口301与第一排水口201相通，壳体303内具有从入水口301至出水口302的排水腔室304(参阅图2、3)。
优选的，所述入水口301设于壳体303与洗涤桶200外周壁相邻一侧的侧壁3031上，密封罩住洗涤桶的第一排水口201。
进一步优选的，所述出水口设于远离洗涤桶外周壁的壳体侧壁上(图中未示出)，或者，出水口302出水方向向下设置(参阅图2、3)。
实施例三
本实施例与上述实施例的区别为，如图2和图3所示，所述排水通道300和洗涤桶200的外壁配合形成排水腔室304，排水通道300包括罩体305，罩设在洗涤桶200外周壁上，与洗涤桶200外周壁配合形成向下排水的腔室304，第一排水口201构成腔室的入水口301，腔室304的下部具有出水口302。
进一步的，所述出水口设于罩体上，或者，罩体与洗涤桶外周壁之间具有的向下的开口构成出水口(图中未示出)。
实施例四
如图1和图5所示，本实施例的一种洗衣机，包括洗涤过程中可用于盛水的洗涤桶200和用于收集洗涤桶200排放水的接水装置500，所述的接水装置500包括集水腔501和与集水腔501相通的第二排水口502，排水通道300向下排水的出水口302位于集水腔501内。
优选的，构成集水腔的周壁503上沿高于排水通道300的出水口302所在位置的高度。
更优选的，集水腔的周壁503上沿不高于第一排水口201所在位置的高度。
本实施例洗涤桶周壁高于第一排水口201的上方为密封结构，洗涤桶200内部通过周壁下部的第一排水口201与外部相通，也即，洗涤桶周壁除第一排水口201的其它区域为密封结构。
洗涤桶200作为洗衣机的盛水桶，洗涤桶200外部不再设置外桶，只在洗涤桶200的底部设置接水装置500，这样，洗涤桶的洗涤水排放至接水装置500后再由第二排水口502排出，因此接水装置500的集水腔501具有接水、集水的功能，接水装置500的高度小于洗涤桶200的高度，洗涤桶200的底部位于集水腔501内，至少洗涤桶的上部分伸出于集水腔501的上部开口外部。
实施例五
本实施例的洗衣机的洗涤桶200为“无孔内桶”，洗涤过程中洗涤桶200即为盛水桶，洗涤桶200的桶壁的下部设置有第一排水口201，实现脱水功能，同时，在洗涤桶200的桶壁上设置排水通道，将洗衣机脱水过程中的水经排水通道引导至接水装置500的集水腔501内收集并排出，防止脱水的水流飞溅到洗衣机的箱体内。
本实施例所述集水腔501的底壁设置用于引导水流至第二排水口502的导水结构，可以确保水流及时排出，防止接水装置500积水过多过快发生溢流。所述集水腔501的全部底壁或者部分底壁呈由高向低的过渡设置形成所述导水结构，所述的第二排水口502设置在集水腔501的底壁上最高水位以下位置处。这样，排水可沿着集水腔501的导水结构更好的排放至第二排水口502处排出。
实施例六
本实施例所述集水腔501的底壁设置下凹的环形凹槽504，环形凹槽504向下延伸低于集水腔501底壁所在的高度，所述环形凹槽504在竖直方向的深度呈由高向低的过渡设置形成所述导水结构，所述的第二排水口502设置在环形凹槽504内且位于最低位置处，排水通道300的出水口302设于环形凹槽内。本实施例在集水腔501内设置下凹的环形凹槽504， 一方面可以增大收集水的容积，另一方面可防止水溅出来。由于集水腔501内环形凹槽的水位最低，因此，将第二排水口502设置在环形凹槽内更利于排水。
具体地，本实施例所述的环形凹槽504沿集水腔501的底壁周向环绕设置，所述环形凹槽504在竖直方向的深度以顺时针或者逆时针方向呈由高向低的过渡设置形成所述导水结构。
优选地，所述环形凹槽504的深度沿与洗涤桶200脱水时转向相同的方向由高到低变化设置。
作为本实施例的一种优选实施方式，所述环形凹槽504的槽底呈由高向低的螺旋状结构或者台阶状结构，所述第二排水口502设置在环形凹槽内且位于螺旋状结构或者台阶状结构的最低水位位置处。这样，可以使得排水能够完全排尽，避免集水腔501内留存水。
实施例七
本实施例的接水装置500位于洗涤桶200的下方且与洗涤桶共轴线设置，所述的排水通道300包括自上而下延伸至接水装置500的环形凹槽504内的部分结构；所述环形凹槽504在竖直方向的深度沿洗涤桶脱水时旋转的方向逐渐增大。本实施例将排水通道300延伸至接水装置500的环形凹槽504内，可将脱水过程的水收集在环形凹槽504内并排出，同时环形凹槽504深度大于集水腔501，可防止脱水排水飞溅。
本实施例的接水装置500为内部具有空腔的盆状结构。所述的接水装置500通过吊杆700吊装在洗衣机的箱体100内，接水装置500的外周壁上设置用于装配吊杆700的吊杆安装座505，优选地，所述的吊杆安装座包括四个，沿其周向均匀分布。
本实施例的接水装置500的底壁上安装驱动装置600，驱动装置具有驱动洗涤桶200和波轮800转动的洗涤桶轴和波轮轴。
实施例八
如图1和图3所示，本发明洗衣机所述洗涤桶200的内周壁还设有自上向下引导水排出的导水通道400，导水通道400下部罩设所述第一排水口201，上部设有进水口401且限定出与进水口401和第一排水口201连通的导水腔室402，导水腔室402通过进水口401与洗涤桶200内部相通。
进一步的，所述导水通道400、第一排水口201、排水通道300依次相通构成洗涤桶200由内向外脱排水的通路。
本实施例所述第一排水口201为至少一个，所述导水通道400为至少一个，每个导水通道400下部罩设至少一个相对应的第一排水口201。
优选的，所述第一排水口201为至少两个且沿洗涤桶200的周向间隔设置，所述导水通道400为至少两个且沿洗涤桶200的周向间隔设置。
进一步的，所述导水通道400为一独立的结构，导水通道400内设有导水腔室，或者，导水通道400和洗涤桶200的内周壁配合形成导水腔室(参阅图7和图8)，该导水通道与洗涤桶的安装结构可参考排水通道设计。
如图7和图8所示，所述进水口401设于导水通道400的径向侧壁403上，优选的，设于与洗涤桶200脱水转动方向一致的径向侧壁上，进水口401开口方向与洗涤桶脱水转动方向一致。
优选的，本实施例的洗涤桶200的开口上设置平衡环900，导水通道400与洗涤桶200脱水转动方向一致的径向侧壁403与平衡环900之间具有一间隙，构成所述的进水口401(参阅图7)，反向的径向侧壁404延伸至平衡环900的下表面，优选与平衡环900的下表面密封设置。
实施例九
如1、图9至图15所示，本实施例洗衣机的洗涤桶200作为盛水桶，洗涤桶200外部不再设置外桶，本实施例只在洗涤桶200的底部设置接水装置500，这样，洗涤桶的洗涤水排放至接水装置500后排出，因此接水装置500具有集水腔501以实现暂时存水的功能。虽然本实施例的洗衣机不再具有外桶，但是洗涤桶200的底部还是设置在接水装置500的集水腔内的，因此，洗涤桶200需要与接水装置的集水腔之间保持相对确定以防止洗涤桶脱水时与接水装置之间发生碰撞，本实施例通过在集水腔501的周壁503上设置用于增加其强度的加强结构，增加了接水装置的整体强度，防止接水装置变形导致内外桶之间的间距变小而产生“撞桶”甚至“磨桶”等现象，保证了洗涤桶洗涤、脱水工况的稳定性。
如图9及图11所示，本实施例所述的加强结构为内嵌注塑在集水腔的侧壁内的加强件。本实施例通过将加强件注塑进集水腔的侧壁内从而实现增强集水腔侧壁的强度的目的。
如图9及图10所示，作为本实施例的一种实施方式，所述的加强件为与集水腔501的侧壁相匹配的片状加强圆环1001，所述片状加强圆1001环竖直内嵌注塑在集水腔501的侧壁内。这样，使得集水腔501的侧壁在整个竖直方向上都受到内嵌的片状加强圆环1001的增强 作用，整体强度更高。
或者，如图11及图12所示，所述的加强件为与集水腔501的侧壁相匹配的钢丝状加强圆环1002，所述接水装置包括集水腔开口，所述的钢丝状加强圆环1002内嵌注塑在集水腔501的侧壁内且靠近集水腔开口设置。钢丝状加强圆环1002在整个周向上贯穿集水腔501的侧壁，以增强其整个周向上的强度，靠近集水腔开口设置可以保证集水腔开口处的强度不易变形。
如图13、图14所示，作为本实施例的一种实施方式，所述的加强结构为紧固在集水腔的侧壁内部加强件，所述加强件的外径略小于所述集水腔的侧壁内径；
或者，所述的加强结构为紧固在集水腔的侧壁外部加强件，所述加强件的内径略大于所述集水腔的侧壁外径。
如图13所示，所述的加强件为与集水腔的侧壁相匹配的片状加强圆环1003，所述片状加强圆环1003通过夹持装置1100紧固在集水腔501的周壁503内部或者外部。
本实施例所述的加持装置1100包括卡槽1101，加持装置1100通过卡槽将片状加强圆环1003卡装在集水腔501的周壁503内部或者外部。
进一步地，本实施例所述的片状加强圆环1003上端开口具有翻边结构10031，以进一步增强片状加强圆环1003的整体强度。
或者，如图14所示，所述的加强件为与集水腔的侧壁相匹配的钢丝状加强圆环1004，钢丝状加强圆环1004由紧固螺母10041连接呈封闭圆环，所述接水装置500包括集水腔开口，所述钢丝状加强圆环1004通过调节紧固螺母10041将其紧固在集水腔501的周壁503内部或者外部且靠近集水腔501开口设置。
再或者，如图15所示，所述接水装置500包括集水腔开口，所述的加强结构为由集水腔开口边沿向外或者向内翻边的翻边结构1005。
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。
