Characteristics Of Product; Working Principle - Midea l712wmb16 Service Manual

2.INTRODUCTION OF PRODUCTS
2.1 C haracteristics of product
It is the latest designed machine, which have many advantages such as fashion, large rated washing
capacity and large washing range. Specifically, its feature is as following:
1.Large washing range from cotton to wool and silk.
2.Gentle washing: no twist and little abrasion.
3.Electron auto-balance system, that is, the PCB panel controls the speed of spin and ensures uniform
distribution of clothes to reduce the wear of textile caused by its vibration.
4.The drum of this machine is made of stainless steel of high quality and the cabinet is durable.
5.The maximum temperature of washing water could be controlled independently and it is up to 90℃.
6.Unique washing methods: rain, soak, throwing-knocking knead and so on, which can wash clothes
uniformly and improve washing performance.
7.Safety guard: water level control, door lock etc.
8.Anti-crease function: there is an automatic anti-crease and soak function in the synthetic program,
that's, it doesn't drain at the end of washing and leave the clean extile in the water of the drum to
achieve the function of less crease, especially delicate.
9.Function of adjusting speed : select different spin speed according to textile.
10.Electronic water distribution system: The machine uses PCB to control the inlet valve and distribute
water properly at the different stages and dissolve detergent and softener absolutely to improve
washing performance.

2.2.Working principle

Drum washing machine wash clothes mainly in virtue of mechanical friction, chemical force and
temperature force. When the machine works, the motor runs clockwise several seconds and runs
anti-clockwise several seconds to drive the drum whose three lifters hold up the clothes pressing
against the inside of the drum. When clothes rise close to the
and the centrifugal force is not enough to overcome the gravity, clothes fall and impinge with washing
liquid (like manual throwing-knocking washing). The second force is the extrusion force of clothes
(like manual extrusion). The last force is the friction between clothes, clothes and lifters(like manual
knead). To improve washing performance, automatic drum washing machine could automatically heat
the washing liquid, whose temperature can be adjusted from 0℃ to 90℃.
The high temperature quickens the movement of the numerator of the washing liquid and speedups the
Chemical reaction. In a word, drum washing machine destroys bonding force between dirt and clothes
in virtue of intergraded force of water, detergent and mechanical force, to clean away the dust.
