滚筒洗衣机柔性复合驱动技术研究

Research on flexible composite drive technology of drum washing machine

介绍了适用于滚筒洗衣机的柔性复合驱动技术,分析了柔性复合驱动技术的结构支撑以及洗涤、脱水原理。具体方法为:在内筒后部端面上增加一套辅助动力搅拌装置,搅拌器与内筒旋转方向相反,使内筒洗涤的衣物在搅拌器的作用下,产生一个逆向的反转力,增加洗涤效果。关键点在于:增加的这套辅助洗涤采用柔性驱动,在搅拌装置承受的反作用力大于一定的扭矩时,辅助洗涤装置会自动停止转动,并非强制驱动,有效的防止辅助洗涤装置在承受大扭矩时的损伤,也有效的保护了衣物,防止其被强制洗涤扭矩破损。该技术可提高滚筒洗衣机的洗净比,并可通过冷水洗涤方式洗干净衣物,同时,采用柔性驱动,具有过载保护功能。

Introduces the flexible composite drive technology suitable for drum washing machines,and analyzes the structure support,washing and dehydration principles of the flexible composite drive technology.The specific method is to add a set of auxiliary power mixing device on the end face of the inner cylinder,and the direction of rotation of the agitator is opposite to that of the inner cylinder,so that the clothes washed in the inner cylinder under the action of the agitator produce a reverse reversal force and increase the washing effect.The key point is that the added set of auxiliary washing adopts a flexible drive.When the reaction force of the mixing device is greater than a certain torque,the auxiliary washing device will automatically stop rotating instead of being forced to drive,which effectively prevents the damage of the auxiliary washing device when it is subjected to large torque,and also effectively protects the clothes from being damaged by the forced washing torque.The technology can improve the washing ratio of the drum washing machine,and can wash clothes by cold water washing,at the same time,the flexible drive has overload protection function.
