Description

一种洗衣机用衣物提升装置及滚筒洗衣机 技术领域
本发明涉及洗衣设备技术领域,具体地,涉及一种洗衣机用衣物提升装置及滚筒洗衣机。
背景技术
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,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;另外,该专利的排水主要通过筒型构造结合驱动装置的高速驱动实现,筒型结构复杂,且排水效果、内筒封闭效果均无法保证,实际应用将存在诸多问题。
