The document provides an overview of washing machine control systems. It discusses the parts and control knobs of a washing machine, and describes the washing cycle and how the motor rotates at different speeds for wash and spin cycles. It presents algorithms for washing machine control and diagrams the open and closed loop control systems. The remainder of the document details microcontroller-based control systems, circuit diagrams, programming commands, and interfacing washing machine control with microprocessors.

16. WORKING OF WASHING MACHINE
•A slow motor turns a shaft with many disks with
bumps on them.
•The bumps activate micro switches which control
water on and off, heater on and off, the main motor at
different speeds (wash and spin) and the pump for
emptying.
•It controls the programming of the machine i.e.
Temp control, Spin cycles.

Notas do Editor
A solenoid valve is an electromechanically operated valve. The valve is controlled by an electric current through a solenoid: in the case of a two-port valve the flow is switched on or off; in the case of a three-port valve, the outflow is switched between the two outlet ports. Multiple solenoid valves can be placed together on a manifold.
Solenoid valves are the most frequently used control elements in fluidics. Their tasks are to shut off, release, dose, distribute or mix fluids. They are found in many application areas. Solenoids offer fast and safe switching, high reliability, long service life, good medium compatibility of the materials used, low control power and compact design.
