Description

滚筒洗衣机及其控制方法 技术领域
本发明属于洗衣机技术领域，具体提供一种滚筒洗衣机及其控制方法。
背景技术
滚筒洗衣机依据棒锤击打衣物的原理设计而成的，其具有低磨损、不缠绕、可洗涤羊绒、真丝织物以及容量大等诸多优点。
现有的滚筒洗衣机都设有窗垫，窗垫用于连接洗衣机的前面板开口和外筒开口以保证洗衣机的密封性。在洗涤衣物时，外筒会产生振动位移，为防止洗衣机损坏，窗垫由柔性材料制成且形成有褶皱部，以使其具有适当的弹性伸缩性能。在洗涤过程中，洗涤水会进入到窗垫的褶皱部内，并会存积在该褶皱部的下部区域，该下部区域是褶皱部在竖直方向上位于最低点的一段圆弧，在重力的作用下，洗涤水中附着的脏污颗粒会沉淀并积聚在该区域内，由于窗垫的结构较为复杂且与滚筒的连通不是很通畅，会导致该褶皱部的下部区域的洗涤水几乎处于静止的状态，而且即使内筒转动也并不能带动这部分洗涤水剧烈流动，长此以往会形成顽固污垢，并且由于污垢位于褶皱部内，十分不便于进行清理。由此可见，目前的滚筒洗衣机在使用过程中，其窗垫的褶皱部的下部区域极易形成顽固污垢且不便清理。
因此，本领域需要一种新的滚筒洗衣机及其控制方法来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有滚筒洗衣机的窗垫的褶皱部的下部区域极易形成顽固污垢且不便清理的问题，本发明提供了一种滚筒洗衣机，滚筒洗衣机包括滚筒、窗垫、排水组件和清洁组件，滚筒包括外筒和转动设置在外筒中的内筒，窗垫和排水组件分别与外筒连接，窗垫包括褶皱部，清洁组件的进水口与 排水组件连接，清洁组件的排水口与褶皱部连接并朝向褶皱部的下部设置。

基于背景技术指出的现有滚筒洗衣机的窗垫的褶皱部的下部区域极易形成顽固污垢且不便清理的问题，本发明提供了一种滚筒洗衣机及其控制方法，旨在利用滚筒排水来对窗垫的褶皱部的下部区域进行清洗，避免形成顽固污垢，使得用户无需反复清理，提升用户体验，且有利于环保。
具体地，参阅图1，本发明的滚筒洗衣机包括滚筒1、窗垫2、清洁组件3和排水组件4。其中，滚筒1包括外筒和转动设置在外筒中的内筒，窗垫2的一端与外筒连接，另一端与滚筒洗衣机的前面板的门体开口(图中未示出)连接，窗垫2包括起缓冲和密封作用的褶皱部，排水组件4与外筒连接，清洁组件3包括进水口和排水口，进水口与排水组件4连接，排水口与窗垫2的褶皱部连接并朝向褶皱部的下部设置。外筒内的洗涤水可通过排水组件4排出，清洁组件3能够使排水组件4内的一部分洗涤水由进水口进入并由排水口排出，由此清洁褶皱部的下部。
本发明的清洁组件3具有多种实施方式，下面结合附图并通过具体的实施例对清洁组件3进行说明。
实施例一
参阅图1，清洁组件3包括泵构件31、第一连通件32和第二连通件33，泵构件31通过第一连通件32与排水组件4连接，泵构件31通过第二连通件33与窗垫2的褶皱部连接，第二连通件33的排水口朝向褶皱部的下部设置。泵构件31使洗涤水在一定压力下通过第二连通件33并排出，由此对褶皱部的下部起到清洁的作用。
实施例二
参阅图1和图2，清洁组件3包括泵构件31、第一连通件32和第二连通件33，泵构件31通过第一连通件32与排水组件4连接，泵构件31通过第二连通件33与窗垫2的褶皱部连接，第二连通件33的排水口朝向褶皱部的下部设置，第二连通件33包括连通管路和喷射结构34，连通管路的两端分别与泵构件31和喷射结构34连接，喷射结构34伸入到褶皱部的内部，并且喷射结构34的排水口朝向褶皱部的下部设置，通过喷射结构34可进一步增强对褶皱部的下部的冲刷效果。
实施例三
参阅图1和图3，清洁组件3包括泵构件31、第一连通件32和第二连通件33，泵构件31通过第一连通件32与排水组件4连接，泵构件31通过第二连通件33与窗垫2的褶皱部连接，第二连通件33的排水口朝向褶皱部的下部设置，第二连通件33包括第一连通管路331、第二连通管路332、第一喷射结构333和第二喷射结构334。第一连接管路331的两端分别与泵结构31和第一喷射结构333连接，第二连接管路332的两端分别与泵结构31和第二喷射结构334连接。第一喷射结构333和第二喷射结构334均伸入到褶皱部内，并且第一喷射结构333和第二喷射结构334的排水口均朝向褶皱部的下部设置。窗垫2呈环形，其在竖直方向上位于最低点的一段圆弧区域为窗垫2的褶皱部的下部区域301，第一喷射结构333和第二喷射结构334分别设置在下部区域301的左右两侧或者同时设置在下部区域301的左侧或右侧。由此使第一喷射结构333的排水口和第二喷射结构334的排水口分别位于下部区域301的两侧或同一侧，由于外筒内的脏污颗粒大多聚集在该下部区域301内，当第一喷射结构333和第二喷射结构334同侧布置时，可增加洗涤水的流速和流量，进而提升对下部区域301的冲刷效果，可有效提升清洁能力，当第一喷射结构333和第二喷射结构334异侧布置时，可使下部区域301的左、右两侧同时受到洗涤水的冲刷，即使下部区域301获得双向的冲刷，具有较好的清洁效果。
实施例四
参阅图1和图4，清洁组件3包括多个用于清洗窗垫2的褶皱部的清洁机构，该清洁机构包括泵构件31、第一连通件32和第二连通件33，泵构件31通过第一连通件32与排水组件4连接，泵构件31通过第二连通件33与窗垫2的褶皱部连接，并且第二连通件33的排水口朝向褶皱部的下部设置。泵构件31使洗涤水在一定压力下通过第二连通件33并排出，由此可对褶皱部的下部起到冲刷清洁的作用。在本发明中，清洁机构的数量可以任意调整，例如清洁机构的数量为两个(图4中所示的正是这种结构)，当然，清洁机构的数量还可以为三个、四个等，本领域技术人员可以在实际应用中根据滚筒洗衣机 的具体结构对清洁机构的数量进行灵活地设定，这种对清洁机构数量的调整和改变均不构成对本发明的限制，均应限定在本发明的保护范围之内。
实施例五
参阅图1、图2和图4，清洁组件3包括多个用于清洗窗垫2的褶皱部的清洁机构，该清洁机构包括泵构件31、第一连通件32和第二连通件33。泵构件31通过第一连通件32与排水组件4连接，通过第二连通件33与窗垫2的褶皱部连接。第二连通件33的排水口朝向褶皱部的下部设置。第二连通件33包括连通管路和喷射结构34，连通管路的两端分别与泵构件31和喷射结构34连接，喷射结构34伸入到褶皱部的内部，并且喷射结构34的排水口朝向褶皱部的下部设置。通过喷射结构34可进一步提高对褶皱结构的下部的冲刷效果。
参阅图1和图5，对于上述的清洁组件3，本领域技术人员还能够理解的是，泵构件31是用于输送洗涤水的泵，可以是离心泵、容积式泵和动力式泵，优选为循环泵，第一连通件32和第二连通件33用于传输洗涤水，可以是柔性软管、弯管或接头等，优选为软管，并且第二连通件33可单独伸入到褶皱部内，由第二连通件33直接清洗褶皱部的下部，此时，第二连通件33的排水口可设置为扁平状，由此可提升对褶皱部的清洁效果。第二连通件33还可与喷射结构34连接，通过喷射结构34将洗涤水喷出，使洗涤水对褶皱部的下部产生冲刷作用，以提升清洁效果。喷射结构34可以是设置在第二连通件33上的喷头还可以是形成于第二连通件33上的喷射口，在实际应用中，喷射结构34优选为喷头，继续参阅图5，喷头包括相连的第一输送部342和第二输送部343，第二输送部343上设置有喷水口341，第一输送部342连接在第二连通件33上，从第二连通件33排出的水依次经由第一输送部342和第二输送部343并从喷水口341喷出，然后实现对窗垫2的褶皱部的下部进行清洁。此外，喷水口341优选地设置为长条形，从而使喷水口341喷射出的水大范围且快速地喷出，进而提高对窗垫2的褶皱部的下部的清洁效果。
在本发明中，排水组件4用于将外筒内的洗涤水引出和排出，本发明的滚筒洗衣机可以是上排水滚筒洗衣机也可以是下排水滚 筒洗衣机。具体地，当滚筒洗衣机为上排水滚筒洗衣机，排水组件4包括排水泵41、连接管42和排水管43(图1所示的正是这种结构)。连接管42的两端分别连接排水泵41和外筒，第一连通件32与连接管42连接。当洗涤或漂洗结束时可通过排水泵41使外筒内的洗涤水排出，当需要清洁窗垫2的褶皱部的下部时，可通过泵构件31的作用使连接管42内的洗涤水依次通过第一连通件32、泵构件31以及第二连通件33然后喷出，由此使洗涤水循环并对窗垫2的褶皱部的下部进行清洁。当滚筒洗衣机为下排水滚筒洗衣机，排水组件为连接管42、排水管43和排水阀44(图6所示的正是这种结构)。连接管42的两端分别连接排水阀44和外筒，第一连通件32与连接管42连接。当洗涤或漂洗结束时可通过排水阀44使外筒内的洗涤水排出，当需要清洁窗垫2的褶皱部的下部时，可通过泵构件31的作用使连接管42内的洗涤水依次通过第一连通件32、泵构件31以及第二连通件33然后喷出，由此使洗涤水循环并对窗垫2的褶皱部的下部进行清洁。
对于上述的排水组件4，其连接管42与第一连通件32的连接部位位于排水泵41或排水阀44的上游侧，在实际应用中，可以在竖直方向上使第一连通件32与连接管42的连接部位高于排水泵41或排水阀44的所在位置，由此可使在对窗垫2的褶皱部的下部清洁完成后使清洁组件3内的洗涤水自然流向到排水泵41或排水阀44内，在排水泵41或排水阀44的作用下通过排水管43排出外筒，从而避免洗涤水存积在清洁组件3内，进而避免存积的洗涤水滋生细菌、发臭或者形成顽固污垢堵塞清洁组件3和排水组件4。
本领域技术人员还能够理解的是，通过控制排水泵41或排水阀44的启闭可控制连接管42和排水管43的通断，具体地，排水泵41或排水阀44开启时，外筒内的洗涤水可以依次通过连接管42和排水管43排出外筒，可在滚筒洗衣机洗涤或漂洗结束时开启排水泵41或排水阀44，将外筒和清洁组件3内的洗涤水排出。当排水泵41或排水阀44关闭时，外筒内的洗涤水仅能流入到连接管42内，无法经由排水管43排出外筒。由于连接管42与外筒的底部连通，并且连接管42与外筒的连接部位在竖直方向上处于较低的位置，由此可在外筒内洗涤水液位较低的情况下，使外筒内的洗涤水仍然能够进入到连接管 42内。一方面可供清洁组件3抽取，另一方面可在在洗涤或漂洗完成后，将外筒内的洗涤水充分排出避免残留。
本领域技术人员还能够理解的是，本发明通过使排水组件4和清洁组件3与外筒连接，使洗涤水能够在外筒和清洁组件3内循环流动，通过清洁组件3可使洗涤水直接冲刷褶皱部的下部区域301，并带动滞留在下部区域301内的洗涤水流动，对下部区域301进行持续清洁，清洁效果好，可避免形成顽固污垢，有效地解决了现有技术中窗垫的褶皱部内易形成顽固污垢和不便清理的问题。
在另一方面，本发明还提供了一种用于滚筒洗衣机的控制方法，该控制方法依据于上述的滚筒洗衣机的结构实现，在此不作赘述，本发明的控制方法包括：在滚筒洗衣机洗涤和/或漂洗过程中或者洗涤和/或漂洗结束之后，使清洁组件运行；将排水组件中的一部分水循环至褶皱部并对褶皱部的下部进行冲洗。需要说明的是，在滚筒洗衣机对衣物进行清洗时，需要进行多次排水，具体为洗涤后的排水、漂洗后的排水以及脱水后的排水等，为了提高对窗垫的褶皱部的下部区域的清洗效果，外筒中的水量应该较多，从而有足量的水可以对窗垫的褶皱部进行清洗，因此在洗涤和/或漂洗过程中或者洗涤和/或漂洗结束之后(即排水过程中)对窗垫的褶皱部进行清洗最佳。在一种可能的情形中，“使清洁组件运行”的步骤具体包括：使清洁组件持续运行，即清洁组件在启动后持续运行，不间断，从而保持对窗垫褶皱部的清洗。在另一种可能的情形中，“使清洁组件运行”的步骤具体包括：使清洁组件间歇式运行，即清洁组件在对窗垫的褶皱部进行清洗时开一段时间停一段时间，如此交替进行。本领域技术人员可以在实际应用中灵活地设置清洁组件的具体运行方式，只要能够实现对窗垫的褶皱部的下部区域进行清洗即可。
优选地，本发明的控制方法还包括：在滚筒洗衣机排水结束时，关闭清洁组件。即在洗涤和/或漂洗结束时，将清洁组件关闭，从而停止对窗垫的褶皱部进行清洗。进一步地，在“关闭清洁组件”的步骤的同时或之后，本发明的控制方法还包括：关闭排水组件。即，清洁组件停止对窗垫的褶皱部进行清洗的同时或者之后，可以通过排水组件将水、线屑以及脏污颗粒等顺利排出。
下面参照附图并以本发明的滚筒洗衣机是上排水滚筒洗衣机为例并结合具体的实施例对发明中清洁组件对窗垫的褶皱部的下部的清洁方式进行说明。
实施例六：
参阅图7，在对衣物洗涤或漂洗处理过程中清洁窗垫的褶皱部的下部区域，在滚筒洗衣机处于洗涤或漂洗状态时开启循环泵(此时排水泵处于关闭状态)，使循环泵持续工作。洗涤或漂洗结束后滚筒洗衣机开始排水，滚筒洗衣机通过开启排水泵进行排水。排水结束后将循环泵关闭再将排水泵关闭。
实施例七：
参阅图8，在滚筒洗衣机对衣物洗涤或漂洗处理过程中清洁窗垫的褶皱部的下部区域，在滚筒洗衣机处于洗涤或漂洗状态时开启循环泵(此时排水泵处于关闭状态)，使循环泵间歇工作。洗涤或漂洗结束后滚筒洗衣机开始排水，通过开启排水泵进行排水。排水结束后将循环泵关闭再将排水泵关闭。
实施例八：
参阅图9，在滚筒洗衣机对衣物洗涤或漂洗结束前的一段时间(例如时间T)内清洁窗垫的褶皱部的下部区域，在滚筒洗衣机对衣物洗涤或漂洗结束前的一段时间内开启循环泵(此时排水泵处于关闭状态)。洗涤或漂洗结束后开始排水，通过开启排水泵进行排水。排水结束后将循环泵关闭再将排水泵关闭。当然，还可以在洗涤或漂洗结束后的T时间内清洁窗垫的褶皱部的下部区域。
本领域技术人员能够理解的是，本发明对窗垫的褶皱部的下部区域清洁实施例不仅限于上述三种，可以根据需要使本发明的对窗垫的清洁处理发生在洗衣机对衣物洗涤或漂洗的过程中以及洗衣机对衣物洗涤或漂洗开始之前或结束之后的一段时间内，并且，在清洁处理时，循环泵可以间歇或持续运行。
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下， 本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。
