Description

一种滚筒洗衣机
本申请要求在2019年3月13日提交中国专利局、申请号为201910190830.8的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请涉及洗衣设备技术领域，例如涉及一种滚筒洗衣机。
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，例如申请号为CN201410215346.3，名称为一种滚筒洗衣机的中国专利申请，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，该申请的内筒为无孔内筒，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，节约了洗涤用水量。
上述申请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，该申请公开的滚筒洗衣机进水的方式是通过门封，由于门封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。
无孔内筒滚筒洗衣机容易出现密封舱气压不平衡的问题，如突然的电磁阀断水，尤其的是自来水管网断水，容易形成负压，将密封舱内的洗涤水回抽至管网。还存在密封舱内部有气体，进水、排水困难等问题。另外，还会存在内筒的门体和排水口的密封的问题。
