Description
本发明涉及洗衣设备技术领域,具体地,涉及一种滚筒洗衣机。
洗衣机作为人们日常生活中使用最为广泛的一种家用电器,帮助人们摆脱了洗衣的烦恼,给人们带来了极大的便利。但是洗衣机也具有一定的缺点,比如说耗时较长、耗水量较大等,随着社会的发展,水资源作为一种重要的自然资源变得越来越重要,人们的节水意识也随之提高,而如何实现洗衣机的节水功能便显得尤为重要。
为了解决洗衣机的节水问题,现在也提出了一些专利,比如专利号为201410215346.3,名称为一种滚筒洗衣机的中国发明专利,该发明涉及一种滚筒洗衣机,包括箱体,箱体内设有内筒和外筒,外筒与箱体之间设有门封,内筒与驱动装置相连,所述的内筒为无孔内筒,且所述的内筒为筒底处直径小、筒口处直径大的锥形筒,内筒的筒口处向内呈弧形收拢,所述的门封上设有进水导管,进水导管的一端与洗涤水快速加热装置相连,进水导管的另一端穿过门封伸入内筒内,所述的外筒上设有排水口及水压检测装置。由上述技术方案可知,该发明的内筒为无孔内筒,通过设置在门封上的进水导管实现内筒进水,并通过内筒自身的形状在脱水过程中实现排水,这样可以避免在内、外筒之间存水,大幅节约了洗涤用水量。
上述发明提供了一种具有无孔内筒的滚筒洗衣机,但仅仅是将现有滚筒洗衣机的内筒设计为无孔结构,现实意义很小。因为衣物洗涤须有一定的洗涤水浸泡,如果要实现浸泡的效果,无孔内筒中的需要存有一定的水量,这样会增大电机的负担,耗电等问题也随之而来。另外,该专利公开的滚筒洗衣机进水的方式是通过门封,由于门封主要的作用是实现洗衣机外筒的筒口的密封,在门封上设置进水导管容易影响门封的密封效果,不易实现,且该专利不能实现对内筒内进水水位的检测。
另外,本发明主要解决无孔内筒滚筒洗衣机如何保证密封舱气压不平衡的问题,具体是,突然的电磁阀断水,尤其的是自来水管网断水,形成负压,将密封舱内的洗涤水回洗至管网;或者内部有气体,进水困难的问题。
有鉴于此,特提出本发明。
