2. WASHING MACHINE
A washing machine is a machine to wash laundry, such as clothing and sheets.
Washing entails immersing, dipping, rubbing, or scrubbing of clothes in water usually accompanied by detergent, or bleach.
The simplest machines may simply agitate clothes in water while switched on BUT automatic machines may fill, empty, wash, spin, and heat in a cycle.

6. Principle of operation
Operation of Washing Machine is split in THREE cycles.
Wash cycle : - Here clothes are washed in water with Detergent.
Rinse cycle : - Here DIRT which is seperater from clothes is drained.
Dry cycle : - Here clothes are made to be DRIED.

7. Wash Cycle
Earlier washing machines simply carried out a washing action when loaded with clothes and soap, filled with hot water, and started.
Now users put clothes into the machine, select a suitable program via a switch, start the machine, and come back to remove clean and slightly damp clothes at the end of the cycle.

9. Rinse Cycle
Washing machines perform several rinses after the main wash to remove most of the detergent. 
Thus most of water is removed from the washing tub.

10. Dry Cycle
Higher spin speeds remove more water, leading to faster drying.
 If a heated clothes-drier is used after the wash and spin, energy use is reduced if more water has been removed from clothes.

11. Configuration of Washing Machiine
Washing Tub : Plastic, Fiber, metal is used for Tub.
Inlet and Outlet(drain) valves for water
Water Level Sensor and Controller
Temperature Sensor : To control hot water coming inside.
Agitator : It moves clothes in Tub.
