Electronic washing machines work by using an electronic motor to spin an inner steel tub. This motor connects with a gear box, which moves the machine using a variety of speed settings.
Inside each washing machine are two steel tubs, an inner tub and an outer tub. A series of holes across the inner tub allow water to leave, while the outer tub works to keep water in the machine. A gear box is attached to the inner tub, along with three pulleys that move the frame. To prevent vibration becoming a problem, there are disc brakes and damping systems that absorb friction.
At the back of the washing machine, there are two plumbing valves that allow water to enter and exit. These valves feed into a single tube, and one of them features an antisiphon device to prevent water running back out of the machine early into the cycle. There is a pump that circulates the water entering the machine.
To complement the circulating water, there is a drive mechanism that cleans the clothes by moving them backwards and forwards, as well as spinning them around. There is a control panel on the outside of each washing machine. When the user turns the dial or presses a button to make the machine work, it engages contact with a pressure switch that determines the speed and temperature.
