中国洗衣机开始于70年代，最早生产单桶洗衣机，80年代后，开始引日本双桶洗衣机，80年代后期，机械程控器控制的全自动洗衣机出现，90年代初，电脑控制的全自动洗衣机逐渐走向市场，同时开始引进欧洲技术在国内生产滚筒式洗衣机，90年代末期，我国洗衣机年销量已达1000万台。

二、洗衣机的基本原理1）洗衣机的洗涤原理是由模拟人工手搓衣物的原理发展而来的。

手工搓洗衣物时，衣物和衣物间、衣物和搓板间、衣物和手间的摩擦力大小适宜，在洗涤液的作用下，将衣物的污垢清洗干净。

洗衣机洗净衣物的过程也很相似，洗涤过程是在化学力和机械力的共同作用下完成的。

实际也是利用洗涤剂中的化学分子团和污垢的亲和力（结合力），再利用机械方式使它们脱离衣物而溶于水中。

2） 波轮洗衣机的洗涤过程① 水流洗涤：在洗衣机波轮刚开始运转时，衣物不动，水流开始相对衣物运动。

②摩擦洗涤：波轮运转后，衣物和水开始相对桶体一起转动，这时，衣物开始和桶内壁，波轮做相对摩擦运动，使衣物开始洗涤并磨损。

② 一般洗衣机洗净率和磨损成反比，衣物洗的越干净，对衣物磨损越大。

所以，有的洗衣机波轮运转时间为0.5s ，就是为了突出水流洗涤。

三、洗衣机分类1．搅拌式全自动洗衣机： 美洲国家，如：美国及周边国家 特点：波轮为高柱式,波轮旋转小于360。

如左图 2．滚筒式洗衣机： 欧洲国家特点：利用滚筒旋转时将衣物带到滚筒上端然后跌落下来的力量对衣物进行洗涤。

3．波轮式洗衣机：亚洲、东南亚地区，由日本设计的，我国洗衣机初期引进的都是日本的。

1引言本篇设计说明书针对全自动滚筒洗衣机的基本整体结构、传动部分、控制部分进行详细的计算说明，并结合数据绘制三维装配图。

采用PLC为基础的主控制电路编制程序。

该设计包括全自动滚筒洗衣机的PLC控制，主要介绍了全自动洗衣机的工作原理，控制系统的PLC的选型和资源的配置，控制系统程序设计与调试，控制系统PLC程序。

传动系统设计，主要包括带轮的设计，滚筒轴系的设计，V带的设计。

2.全自动滚筒洗衣机的总体设计方案2.1滚筒洗衣机的基本结构滚筒洗衣机种类很多，但是通常情况下其大致结构可分为四部分：外观支撑部分、给水排水部分、传动部分、电气控制和操作系统部分。

外观支撑部分主要是滚筒洗衣机的外形框架，给水排水部分主要指洗衣机的给水系统和排水系统，传动部分主要指洗衣机的带传动及滚筒轮系的传动结构，电气控制部分主要指洗衣机依靠各种电器元件及控制器实现的自动控制部分。

个部分具体组成如下：（1）外观部分包括：箱体、后盖、过滤器门、底板等（2）给水排水部分包括：进水管、排水管、储水槽、电磁阀、洗涤剂回收槽等（3）传动部分包括：多频电机、V带、大小带轮、滚筒轴系等（4）控制部分包括：电脑版、电子模块、电磁阀、程控器、温控器、水位压力开关、水加热管、恒温器、电容、定时器等（5）操作部分包括：操作面板、程序标牌、琴键开关、琴键按钮、调温器旋钮、程控器旋钮、指示灯等12.2滚筒洗衣机各部分的设计方案2.2.1主体部分洗涤部分主要由内筒（不锈钢滚筒）、外筒（盛洗涤液用，又称盛水桶）、内筒叉形架、转轴、外筒叉形架、滚动轴承等组成。

（1）内筒及内筒叉形架内筒又称滚筒。

滚筒是滚筒式洗衣机对衣物进行洗涤，洗涤效果有着直接关系。

内筒用厚度为2-3毫米的抛光不锈钢板卷制而成的。

有直径为3.5-5毫米的圆孔，孔与孔之间的距离大约为15-20毫米。

圆孔自内向外冲刷，翻边向外，内壁光滑，以防洗涤时刮伤衣物。

在滚筒内壁沿轴向有三条凸筋，这三条凸筋在洗涤过程中起举升织物的作用。
