A washing machine, clothes washer, or simply washer, is a machine designed to wash laundry, such as clothing, towels and sheets. The term is mostly applied only to machines that use water as the primary cleaning solution, as opposed to dry cleaning (which uses alternative cleaning fluids, and is performed by specialist businesses) or even ultrasonic cleaners.

All washer machines work by using mechanical energy, thermal energy, and chemical action. Mechanical energy is imparted to the clothes load by the rotation of the agitator in top loaders, or by the tumbling action of the drum in front loaders. Thermal energy is supplied by the temperature of the wash bath. The spin speed in these machines can vary from 500 to 1600rpm.
Modern washing machines are available in two configurations: top loading and front loading.

The top loading design or V-axis clothes washer, most popular in Australia, Canada, the United States and Latin America, places the clothes in a vertically-mounted perf ...more

The fuzzy logic controller of a washing machine basically uses two types of input variables. One is concerned with the degree of dirt on the clothes and the second one is concerned with the type of dirt on the clothes.

A single optical sensor is used to obtain both these inputs. The level of dirt is determined by the clearness of the water which is used to wash the clothes. On the other hand, the kind of dirt is determined by the time it takes to reach the point of saturation.

In other words, if the clothes are very dirty, the transparency of the water will be very low. If they are greasy, the duration of time it will take the change in the transparency of water to reach close to zero will be longer.

Like a real fuzzy washing machine would, our model first tests how dirty the laundry is. Once it knows how dirty the laundry is, it can easily calculate how long it should wash it. To calculate this it uses the graph below:

First it always takes a base of 10 minutes. It does this so that people are happy with its work even if they put completly clean laundry in to wash. It then calculates to what degree it is dirty. If it is 100% dirty it adds two minutes per piece of laundry. Of course a real washing machine would just do these calculations in the end, but our model does it for each individual piece so you can keep track of what is going on easier.

So if you now add a piece which is only 50% dirty, it will add 50% of 2 minutes; it adds 1 minute instead of 2 minutes to the base of 10 minutes.

Our washer, however, doesn't only check for dirt but also for grease. Laundry which is greasy has to be washed longer too. Since the laundry can be greasy and dirty at the same time, w ...more
