摘 要

现有的洗衣机中最为常见的为波轮式洗衣机和滚筒式洗衣机。波轮式洗衣机是依靠波轮的转动来带动衣物和洗涤液进行洗涤；而滚筒式洗衣机是依靠滚筒的连续转动或定时反向来洗涤衣物。由此可看出，这两种类型的洗衣机都是依靠单一的运动方式来洗涤衣物，而在此设计中将这两种洗涤方式揉和起来，将两种运动方式结合起来，增加了衣物在竖直方向上的运动。使衣物既能像在波轮式洗衣机中那样由波轮带动衣物进行洗涤又能像滚筒式洗衣机那样依靠水流的力量洗涤衣物，并且还可以像手洗那样对衣物进行揉搓，集各种洗涤方式于一身，对衣物进行更为彻底的洗涤。由于洗衣机的基本功能是对衣物的洗涤，关键在于进行洗衣程序的控制。所以,本文就洗衣机的机械设计和电气控制进行了探讨,实现全自动揉搓式洗衣机的设计

Abstract ：
In what the existing washer is most common is the impeller type washer and the roller washer. The impeller type washer is depends upon impeller's rotation to drive the clothing and the cleaning solution carries on the wash; But the roller washer is depends upon drum's continuous rotation or fixed time reverse washes the clothing. From this may see, these two type's washer is the dependence sole mode of motion washes the clothing, but kneads together in this design these two wash way, unifies two modes of motion, increased clothing's in vertical direction movement. Enables the clothing both to look like in the impeller type washer such drives the clothing by the impeller to carry on the wash and to be able to look like the roller washer such dependence current of water the strength wash clothing, and may also look like the hand to wash such carries on to the clothing rubs, the collection each wash way in a body, carries on a thorougher wash to the clothing. Because washer's basic function is to clothing's wash, therefore, the key lies in carries on washes clothes the procedure control. Therefore, this article has carried on the discussion on washer's machine design and the electric control, realizes the completely automatic to rub type washer's design
key word: The impeller drum rubs the completely automatic
