Electrical circuit of the washing machine
The electrical system of a washing machine consists of the following main components:
*Power supply (socket)
* Power cable
*Ground wire
* Control Panel
* Timer
* Solenoid valve
* Electric motor
* Pump
* Heating element
How the system works
1. Power connection: When the washing machine is plugged into a power outlet, electric current flows into the power cord.
2. Grounding: The grounding wire provides a safe ground for the washing machine by draining excess current to ground in the event of a fault.
3. Control Panel: The control panel accepts user commands and activates the appropriate wash cycle.
4. Timer: The timer controls the duration of each stage of the wash cycle, including wash, rinse and spin.
5. Solenoid valve: The solenoid valve opens and closes under timer control to control the water supply to the washing machine.
6. Electric motor: An electric motor rotates the washing machine drum during the wash and spin cycles.
7. Pump: The pump drains the washing machine after each cycle step.
8. Heating Element: The heating element heats the water to the set temperature for hot wash cycles.
Step by step process of the wash cycle
1. The user loads laundry into the drum and selects a wash cycle.
2. The timer starts the cycle by activating the solenoid valve to supply water to the drum.
3. The heating element heats the water when the hot wash cycle is selected.
4. An electric motor rotates the drum, passing the laundry through water and detergent.
5. The timer controls the duration of the washing phase.
6. The timer activates the pump to drain the water from the drum.
7. The timer activates the solenoid valve to supply rinse water.
8. The pump drains water from the drum again.
9. The timer activates the electric motor to spin the laundry.
10. The cycle ends when the timer turns off all components.
