How does a Washing Machine works There are mainly two types of washing machines, fully automatic and semiautomatic. Now-a- days, fully automatic machines are getting popular. So, let’s take them for further discussion. The basic idea of a clothes washer is simple: it sloshes your clothes about in soap suds for a while and then spins fast to remove the water afterward. But there's a bit more to it than that. Think of a clothes washer and you probably think of a big drum that fills with water—but there are actually two drums, one inside the other. The inner drum is the one you can see when you open the door or the lid. In a front-loading clothes washer, the drum stands upright. You push your clothes inside the door from the front and the whole drum rotates about a horizontal axis (like a car wheel). The drum has lots of small holes to let water in and out and paddles around the edge to slosh the clothes around. In a top loader, more common in the United States and Asia, you open a lip on top and drop your clothes into the drum from above. The drum is mounted about a vertical axis but doesn't actually move. Instead, there's a paddle in the middle of it called an agitator that turns the clothes around in the water.
There's a second, bigger drum outside the inner drum that you cannot see. Its job is to hold the water while the inner drum (in a front-loader) or the agitator (in a top loader) rotates. Unlike the inner drum, the outer drum has to be completely water-tight—or you'd have water all over the floor! The two drums are the most important parts of a clothes washer, but there are lots of other interesting bits too. There's a thermostat (thermometer mechanism) to test the temperature of the incoming water and a heating element that warms it up to the required temperature. There's also an electrically operated pump that removes water from the drum when the wash is over. There's a mechanical or electronic control mechanism called a programmer, which makes the various parts of the clothes washer go through a series of steps to wash, rinse, and spin your clothes. There are two pipes that let clean hot and cold water into the machine and a third pipe that lets the dirty water out again. All these pipes have valves on them (like little doors across them that open and shut when necessary). The programmer makes the inner drum rotate back and forth so the clean water rinses the clothes. It empties both drums and repeats this process several times to get rid of all the soap. When the clothes are rinsed, the programmer makes the inner drum rotate at really high speed—around 80 mph (130 km/h). The clothes are flung against the outside edge of the inner drum, but the water they contain is small enough to pass through the drum's tiny holes into the outer drum. Spinning gets your clothes dry using the same idea as a centrifuge.
