Description

洗衣设备 技术领域
本发明属于洗衣技术领域，具体提供一种洗衣设备。
背景技术
洗衣设备是能够对衣物进行洗涤、漂洗、脱水和/或烘干的衣物处理设备。
以滚筒洗衣机和滚筒式洗干一体机为例，其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，在对衣物进行洗涤之后，筒组件内部都非常潮湿，潮湿的环境极易使筒组件内部滋生细菌，且会产生异味，而仅仅将门体打开也无法杜绝这种情况发生，且用户再次使用洗衣机时也会对新添加的衣物形成二次污染，不利于用户的使用，影响用户的正常体验。
因此，本领域需要一种新的洗衣设备来解决上述问题。
发明内容
为了解决现有技术中的上述问题，即为了解决现有洗衣设备在对衣物洗涤之后其筒组件内部十分潮湿而易滋生细菌和产生异味，且会对后续洗涤的衣物形成二次污染的问题，本发明提供了一种洗衣设备，所述洗衣设备包括筒组件、衣物处理剂投放盒和进水管，所述进水管的入口与所述衣物处理剂投放盒连通，所述进水管的出口与所述筒组件连通，所述洗衣设备还包括将外界与筒组件连通的进风管和与所述进水管连接的吸水管，所述吸水管与所述洗衣设备的排水泵连接，所述进风管中设置有进风风机，所述排水泵设置为在所述洗衣设备执行通风程序时能够通过所述吸水管将所述进水管中的水排出，以便所述进水管与外界连通。
在上述洗衣设备的优选技术方案中，所述进水管为U型进水管，所述吸水管的最高位置位于所述U型进水管的入口所处的高度位置与所述U型进水管的出口所处的高度位置之间。
在上述洗衣设备的优选技术方案中，所述吸水管与所述U型进水管的横段的底部连通。
在上述洗衣设备的优选技术方案中，所述筒组件包括外筒、转动设置在所述外筒中的内筒和与所述外筒连接的窗垫，所述进风管与所述窗垫的褶皱部连通。
在上述洗衣设备的优选技术方案中，所述进风管与所述窗垫的褶皱部的顶部连通。
在上述洗衣设备的优选技术方案中，所述筒组件包括外筒、转动设置在所述外筒中的内筒和与所述外筒连接的窗垫，所述进风管与所述外筒连通。
在上述洗衣设备的优选技术方案中，所述进风管与所述外筒的顶部连通。
在上述洗衣设备的优选技术方案中，所述进风管内设置有防泡沫溢出构件。
在上述洗衣设备的优选技术方案中，沿所述进风管的进风方向，所述进风风机设置在所述防泡沫溢出构件的上游侧。
在上述洗衣设备的优选技术方案中，所述进风管内设置有空气过滤构件。
本领域技术人员能够理解的是，在本发明的优选技术方案中，通过设置进风管和与洗衣设备的进水管连接的吸水管，且吸水管与洗衣设备的排水泵连接，使得在洗衣设备正常洗涤时能够通过进水管向筒组件中注水，此时进水管中有水形成水封，当洗衣设备洗涤完成后执行通风程序时，进风风机和排水泵打开，外界空气由进风管进入到筒组件中，然后筒组件中的空气进入到进水管中，排水泵通过吸水管将进水管中的水排出，使得进水管与外界连通，利用进水管进行出风，通过这样的设置，在尽可能不改变原有洗衣设备的结构的情况下即可使洗衣设备具备通风功能，使得在对衣物进行洗涤之后可以将筒组件内部的残留水风干，保证筒组件内部干燥，避免滋生细菌以及产生异味，且用户在使用洗衣设备再次对衣物进行洗涤时也不会使衣物受到二次污染，而且无需对洗衣设备进行大幅度结构变化，结构简单，节约生产成本，提升用户体验。
进一步地，进水管为U型进水管，在U型进水管进水时，由于吸水管的最高位置高于U型进水管的出口，使得在洗衣设备进水的过程中水不会从吸水管排出，保证U型进水管中的水能够进入到筒组件中，在洗衣设备洗涤完成执行通风程序时，排水泵开启以将进水管中的水排出，进而将进水管与外界连通实现排气，并且由于吸水管的最高位置低于U型进水管的入口，U型进水管中的水不会回流到衣物处理剂投放盒中并发生溢水的情况，保障洗衣设备的安全运行。
进一步地，吸水管与U型进水管的横段的底部连通，使得在洗衣设备执行通风程序时，吸水管能够将U型进水管中的水全部排空，避免U型进水管中有水残留。
进一步地，在进风管中设置防泡沫溢出构件能够使得在洗衣设备洗涤过程中如果产生过多泡沫能够防止泡沫从进风管向外溢出，避免洗衣设备发生溢水溢泡沫的情况，避免影响室内环境，进一步提升用户体验。
进一步地，沿进风管的进风方向，进风风机设置在防泡沫溢出构件的上游侧能够防止进风风机受到泡沫和水的影响，避免进风风机发生短路情况，进一步提高洗衣设备的安全性。
进一步地，进风管中设置空气过滤构件能够防止进入到筒组件中的空气携带灰尘等杂质，保证筒组件的内部不受影响，进一步提升用户体验。

此外，还需要说明的是，在本发明的描述中，除非另有明确的规定和限定，术语“设置”、“连接”、“连通”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域技术人员而言，可根据具体情况理解上述术语在本发明中的具体含义。
基于背景技术指出的现有滚筒洗衣机在对衣物洗涤之后其筒组件内部十分潮湿而易滋生细菌和产生异味，且会对后续洗涤的衣物形成二次污染的问题，本发明提供了一种滚筒洗衣机，旨在尽可能不改变原有滚筒洗衣机的结构的情况下即可使滚筒洗衣机具备通风功能，使得在对衣物进行洗涤之后可以将筒组件内部的残留水风干，保证筒组件内部干燥，避免滋生细菌以及产生异味，且用户在使用滚筒洗衣机再次对衣物进行洗涤时也不会使衣物受到二次污染，而且无需对滚筒洗衣机进行大幅度结构变化，结构简单，节约生产成本，提升用户体验。
具体地，如图1和2所示，本发明的滚筒洗衣机包括箱体1和设置在箱体1中的筒组件，筒组件包括通过多个弹性阻尼件悬置于箱体1内的外筒2、转动设置在外筒2中的内筒3以及与外筒2连接的窗垫4，窗垫4还与箱体1的衣物投放口连接，内筒3采用电机和皮带的组合方式进行驱动或者采用直驱电机驱动，滚筒洗衣机的门玻璃关闭时能够与窗垫4紧密贴合实现密封，滚筒洗衣机还包括衣物处理剂投放盒5(例如洗涤剂盒和柔顺剂盒等)和进水管，进水管的入口与衣物处理剂投放盒5连通，进水管的出口与筒组件连通，外部水进入到衣物处理剂投放盒5中后将衣物处理剂和水一起通过进水管注入到外筒2中，衣物处理剂投放盒5是与外界连通的，进水管的入口所处的高度位置高于进水管 的出口所处的高度位置，进水管优选采用与外筒2连通。在滚筒洗衣机执行洗衣程序时，先通过进水管向外筒2中注水直至达到洗涤水位，然后停止进水，此时进水管中仍有水并形成水封。
如图1和2所示，本发明的滚筒洗衣机还包括将外界与筒组件连通的进风管7和与进水管连接的吸水管9，吸水管9与滚筒洗衣机的排水泵11连接，进风管7中设置有进风风机8，排水泵11设置为在滚筒洗衣机执行通风程序时能够通过吸水管9将进水管中的水排出，以便进水管与外界连通。进风风机8开启后，可以将外界空气通过进风管7引入到外筒2中，外筒2中的空气会进入到进水管中，排水泵11能够通过吸水管9将进水管中的水排出，进而使进水管中的水封解除，外筒2中的空气可以在进入到进水管中后能够继续进入到衣物处理剂投放盒5中，由于衣物处理剂投放盒5与外界连通，使得外筒2内与外界处于导通状态，进而在进风风机8的作用下实现通气通风，从而将筒组件的内部风干同时排出筒组件中的异味，避免滋生细菌以及对后续衣物的洗涤产生二次污染。
优选地，如图1和2所示，进水管为U型进水管6，吸水管9的最高位置位于U型进水管6的入口所处的高度位置与U型进水管6的出口所处的高度位置之间。在滚筒洗衣机正常洗涤时，先向外筒2中注水，外界水(一般接自来水)进入到衣物处理剂投放盒5中再经过U型进水管6的入口进入到U型进水管6中，U型进水管6中的水位不断升高并通过U型进水管6的出口进入到外筒2中，吸水管9的最高位置高于U型进水管6的出口，且洗涤过程中排水泵11关闭，由于连通器的原理U型进水管6中的水只能进入到外筒2中而不会从吸水管9排出，并且在注水完成后，U型进水管6中存水并完全封闭U型进水管6的横段和至少一部分竖段，即对U型进水管6进行水封。在滚筒洗衣机执行通风程序时，进风风机8和排水泵11开启，外界空气被进风风机8引入到进风管7中，然后空气再进入到外筒2中，外筒2中的空气会通过U型进水管6的出口进入到U型进水管6中，排水泵11通过吸水管9将U型进水管6中水排出，使得U型进水管6解除水封，进而气体能够通过U型进水管6的入口进入到衣物处理剂投放盒5中，进而排出到外界，并且由于吸水管9的最高位置低于U型进水管6的入口，U型进水管6中 的水不会进入到衣物处理剂投放盒5中，进而不会使滚筒洗衣机发生溢水情况。在上述中，作为替代性地，U型进水管6还可以替换为V型进水管等结构，本领域技术人员可以在实际应用中根据滚筒洗衣机的内部布置空间灵活地设置进水管的形状以及结构样式，这种对进水管形状以及结构样式的调整和改变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。在一种优选的情形中，吸水管9与U型进水管6的横段的底部连通，通过这样的设置，使得在滚筒洗衣机执行通风程序时能够使U型进水管6中的水完全排空，避免出现残留。
此外，进风管7可以与外筒2连通，还可以与窗垫4的褶皱部连通，当然最优选的是与窗垫4的褶皱部连通，通过这样的设置，使得外界空气能够先进入到窗垫4的褶皱部再进入到外筒2中，能够同时对窗垫4的褶皱部和外筒2进行风干，使得筒组件内部无死角风干，避免筒组件内部滋生细菌，且无需用户反复清理筒组件，同时能够避免对后续洗涤的衣物形成二次污染。进一步地，当进风管7与外筒2连通时，优选与外筒2的顶部连通，避免洗涤时外筒2中的水反流到进风管7中，当进风管7与窗垫4的褶皱部连通时，优选与窗垫4的褶皱部的顶部连通，也避免洗涤时外筒2中的水反流到进风管7中。
优选地，如图1所示，进风管7内设置有防泡沫溢出构件10，防泡沫溢出构件10可以为单向阀，还可以采用风门的组合结构。比如，防泡沫溢出构件10包括门体、第一永磁铁和第二永磁铁，门体转动地设置在进气管内，第一永磁铁设置在门体上，第二永磁铁沿进气管的进风方向设置在门体的上游侧，第一永磁铁和第二永磁铁的磁性相异，当进风风机8开启后，进风风机8产生的空气流能够克服第一永磁铁与第二永磁铁之间的吸力以使门体从封闭位置转动至打开位置，从而使外界的空气进入到外筒2中，当进风风机8停止时，门体通过第一永磁铁与第二永磁铁之间的吸力保持在封闭位置，从而防止泡沫溢出。又比如，防泡沫溢出构件10包括门体、第一永磁铁和第二永磁铁，门体转动地设置在进气管内，第一永磁铁设置在门体上，第二永磁铁进气管的气流方向设置在门体的下游侧，第一永磁铁和第二永磁铁的磁性相同，当进风风机8开启后，进风风机8产生的空气流能够克服第一永磁铁与第二永磁铁之间的斥力以使门体从封闭位置转动至打开位置，从而使外界的空 气进入到外筒2中，当进风风机8停止时，门体通过第一永磁铁与第二永磁铁之间的斥力保持在封闭位置，从而防止泡沫溢出。当然，上述的第一永磁铁和第二永磁铁还可以替换为弹性扭簧，即门体通过弹性扭簧转动地设置在进风管7中，进风风机8开启能够使门体克服弹性扭簧的扭力打开进风管7，进风风机8关闭后弹性扭簧使门体复位关闭进风管7。本领域技术人员可以在实际应用中灵活地设置防泡沫溢出构件10的具体结构，这种对防泡沫溢出构件10具体结构的调整和改变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。在一种优选的情形中，沿进风管7的进风方向，进风风机8设置在防泡沫溢出构件10的上游侧，通过这样的设置，使得进风风机8不会接触到泡沫而发生短路情况，提高滚筒洗衣机的安全性。
优选地，进风管7内设置有空气过滤构件，空气过滤构件可以采用单级过滤网或者多级过滤网的结构，又或者采用其他过滤结构，从而避免外界的脏污进入到外筒2中。
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。
