How Does a Washing Machine Work
Washing machines get clothing clean by plunging the clothes through the water and detergent mixture. It is the motion that really helps to loosen dirt. In the old days, they used to beat wet clothes against a rock to get them clean.
In top loading machines the agitator twists back and forth pulling the clothes down to the bottom of the tub. The clothes then work their way back up to the top where the agitator grabs them again. In a front loading machine, the clothes tumble and are plunged into the water over and over again. After the water is pumped out, the inner drum uses centrifugal force to wring out more water from the clothes by spinning at several hundred RPMs.
While the operation of front loading washing machines is substantially similar to that of top loaders, note that the rest of this article addresses only the top loading style of washing machine.
The design of washing machines vary by manufacturer, but the general principles are essentially the same. The controls consist of a timer, cycle selector mechanism, water temperature selector, load size selector and start button. The mechanism includes the motor, transmission, clutch, pump, agitator, inner tub, outer tub and water inlet valve.
The washer has two tubs, the inner tub with hundreds of holes in it and the outer tub which holds the water. During the spin cycle the inner tub spins, forcing the water out through the holes to the stationary outer tub.
The cycle selector controls may include separate or integrated controls for water temperature, water level, cycle selection and a start switch.
A lid switch, which indicates whether the lid is open or closed, will interrupt some or all of the washing machineoperations.
The water inlet valve connects to the water supply of your home and allows hot and cold water to flow into the tub.
The agitator is in the center of the inner tub. During the wash cycle, the agitator rotates back and forth (about 3/4 of turn) to pull the clothes through the water. At the conclusion of the wash cycle, the water is pumped from the outer tub and into the drain though the drain hose.
The pump, agitator and spin drum are driven by the motor. Some washing machines use direct drive, in which the motor is connected directly to the pump and transmission. Other machines uses a belt drive in which the motor drives the transmission through a pulley and belt. On belt driven machines, the pump is typically connected to the motor by a flexible coupling.
