Description

自清洁滚筒洗衣机及自清洁方法 技术领域
本公开涉及洗涤家电技术领域，例如涉及一种自清洁滚筒洗衣机及自清洁方法。
背景技术
滚筒洗衣机是利用旋转的内筒对衣物予以提升，进而对衣物进行摔打洗涤，然后再通过高速旋转内筒来对衣物进行脱水。为了能够将动力系统的扭矩传递给内筒，通常在内筒底部固定安装三脚架，动力系统通过三脚架带动内筒转动。在洗涤以及高速甩干脱水时，三脚架需要承受很大的力，为了满足结构强度要求，则需要在三脚架上设有加强筋。如此一来，便会造成内筒筒底结构复杂，底面凹凸不平。洗衣机经过长期使用后，内筒底部则会粘附积聚线屑、油脂、灰尘等污垢。随着时间的推移，积存的污垢就会滋生细菌霉菌，产生异味，对洗涤衣物造成二次污染，影响人们的使用体验及身体健康。由于内筒安装在洗衣机内部，且为保证安全，需紧固安装，因此用户不能将其拆下来进行清理。而且由于在洗涤及漂洗过程中，洗涤筒的下部存有一定量的水，内筒的部分筒壁浸没在这些水中，随着内筒转动，这些水对内筒筒壁进行冲刷，因此，内筒筒壁上较为干净，不会粘附污垢。但是，由于内筒筒底的大部分区域都不浸没在水中，故而内筒筒底不能得到充分清洗。相关技术中的洗衣机，带有内筒清洁程序，其过程为将筒内存储水加热到高温，然后转动内筒，利用高温水对筒壁进行冲刷。这种清洁方式存在的问题是，由于门体密封条件的限制，筒内水位设置不能过高，不能将筒底浸没，只能清洁内筒筒壁及内筒筒底的小部分区域；即使密封条件允许设置高水位，将大量的水加热到高温，也将耗费大量的电能，造成能源浪费。

图中：100-外筒、101-集水区、200-第一水管、300-过滤器、301-过滤网、401-排水阀、402-排水管、500-循环水泵、600-循环水管、700-第二水管、800-冲刷喷头、801-冲刷水喷孔。
具体实施方式
如图1所示，一种自清洁滚筒洗衣机，包括：设置有集水区101的外筒100、第一水管200、排水装置和循环喷淋装置，本实施例中，第一水管200的第一端与集水区101相连通，第二端与排水装置相连。循环喷淋装置与第一水管200和外筒100的底部相连通，设置为向外筒100内喷淋清洁水。
如图1所示，在本实施例中，可选地，该自清洁滚筒洗衣机还包括过滤器300，设置为对洗衣后的清洗水加以过滤，该过滤器300的第一端与第一水管200第一端相连通，第二端与循环喷淋装置相连通。
如图1、2、4所示，排水装置包括相连通的排水阀401和排水管402，排水阀401与第一水管200的第二端相连。排水装置除了采用上述结构外还可以选用排水泵连排水管的结构。如图1至图4所示，循环喷淋装置包括依次相连的循环水泵500、循环水管600、第二水管700和冲刷喷头800，循环水泵500与过滤器300相连，冲刷喷头800设置在外筒100的底部。为了便于安装，第二水管700也可以固定在外筒100底部。冲刷喷头800上设置有贯穿外筒100底部且朝向该外筒100内部的冲刷水喷孔801。在本实施例中，如图3所示，冲刷水喷孔801为多个且沿外筒100底部的径向均匀排布，多个冲刷水喷孔801排成一列，各个冲刷水喷孔801的中心连线长度约等于外筒100底部半径长度。冲刷水喷孔801也可以为一个，该冲刷水喷孔801呈扁孔状，能够喷射出扇面状清洁水。在本实施例中，过滤器300中的滤芯为能够拆卸的过滤网301，可由用户定期或者隔一段时间清洁一次，该过滤网301中网孔的轴线垂直于第一水管200的轴线，这一设计可以有效减少用户清洁过滤网的频次。
上述自清洁滚筒洗衣机可在控制面板上设置有“筒清洁”按键，供用户进行操作选择。如图5所示，上述自清洁滚筒洗衣机，自清洁滚筒洗衣机自清洁的方法包括：
用户选择是否进行筒清洁，
选择不进行筒清洁时，按选定的洗衣程序对衣物进行清洗，洗衣机先开始进水，进行常规洗涤，由于洗涤水较为浑浊，因此不采用此洗涤水对内筒底进行清洁，洗涤程序结束后，排水阀401打开，对衣物进行脱水甩干，浑浊的洗涤水经排水阀401及排水管402排出到机外；进入漂洗程序后，排水阀401关闭，循环水泵500开启，滚筒洗衣机进行漂洗，循环水泵500将漂洗水经循环水管600和第二水管700泵送至冲刷喷头800，并由冲刷水喷孔801将漂洗水喷淋至外筒内部，对内筒底进行冲刷清洁，随着内筒转动，对整个筒底进行清洁，将在洗涤过程中粘附在内筒底的污垢冲洗掉。由于设有过滤器300，过滤器300的过滤网301将进入循环喷淋装置的漂洗水中的杂物过滤掉，保证只有较为清洁的漂洗水对内筒底进行冲洗。漂洗程序结束后，循环水泵500停止运转，排水阀401开启，由于过滤网301将漂洗水中的杂物过滤积聚在过滤网301前方的第一水管200内，排水过程中，这些杂物随着水流排出到洗衣机外部，从而实现一定程度上的过滤网301的自动清洁。随着洗衣机工作过程中多次漂洗程序的进行(一般都进行2-3次漂洗)，可以实现长时间的对内筒筒底进行清洁，避免筒底污垢积聚，实现自动清洁。
选择进行筒清洁时(即进行筒清洁)则滚筒洗衣机只进行筒清洁作业，不进行洗衣作业，洗衣机进清洗水，并对清洗水进行加热，加热到85-95℃。关闭排水阀401，开启循环水泵500，循环水泵500将清洗水经循环水管600和第二水管700泵送至冲刷喷头800，并由冲刷水喷孔801将清洗水喷淋至外筒内部，对内筒底进行冲刷清洁，随着内筒转动，将粘附在内筒底的污垢冲洗掉。由于此时使用热水对内筒底进行清洁，不但清洁效果好，而且还具有杀菌消毒的作用，对内筒底滋生的霉菌等进行灭杀。筒清洁程序到时间后，内筒停止转动，循环水泵500停止运转，排水阀401开启，清洗水排出到洗衣机外，同时将过滤网301前被其过滤出的杂物冲走。
本实施例中，该自清洁滚筒洗衣机，自清洁滚筒洗衣机自清洁的方法包括：
选择是否进行筒清洁，
选择不进行筒清洁时，按选定的洗衣程序对衣物进行清洗，进入漂洗程序后，排水装置关闭，循环喷淋装置开启，滚筒洗衣机进行漂洗，循环喷淋装置将漂洗水输送至外筒底部并对该外筒内部进行喷淋；
选择进行筒清洁时，滚筒洗衣机进清洗水，并对清洗水进行加热，关闭排 水装置，开启循环喷淋装置，循环喷淋装置将清洗水输送至外筒底部并对该外筒内部进行喷淋。
本实施例中的自清洁滚筒洗衣机，结构简单，自清洁滚筒洗衣机通过循环喷淋装置向洗衣机外筒底部输送清洁水，并对该外筒内部进行喷淋，从而对滚筒洗衣机的内筒进行冲刷清洁，随着内筒转动，对整个内筒底部进行清洁，将在洗涤过程中粘附在内筒底的污垢冲洗掉；这一自清洁方法，清洗效率高、省时省力且能耗低。
工业实用性
本公开的自清洁滚筒洗衣机，结构简单，能够对整个内筒底部进行清洁，而且清洗效率高、省时省力且节能。
