A washing machine is an electrical appliance used to clean clothes. It combines water, soap (or detergent), and mechanical motion to remove dirt from fabric. The machine typically has a rotating drum, an electric motor, and a control system that regulates the water temperature and cycle time.
Modern washing machines usually have different programs suited to different fabric types: heavy-duty, delicate, or synthetic. Many also have the ability to extract water from clothes by spinning the drum rapidly, which allows clothes to dry faster.
Types
Two main types are common. Front-loading machines have a horizontal drum that rotates the clothes and typically use less water. Top-loading machines have a vertical drum; some use an agitator, a central shaft that moves the clothes. Washer-dryer combinations also exist.
How it works
A typical cycle consists of several steps: filling with water, heating the water (if needed), mixing clothes and detergent together, rinsing with clean water to remove soap, and finally a vigorous spin to remove water. Electronic valves control the water intake, while a small pump drains the waste water outside.
Water and energy
Water and electricity consumption depend on the machine model and the chosen program. Water heating usually accounts for the largest portion of energy use, so lower-temperature programs consume less energy. Many countries rate washing machines for energy efficiency so consumers can compare them.
