We have come a long way from doing laundry washing by hand and hanging clothes to dry, with modern appliances being able to do the process in a very short time with little . There are two general appliance classes of rotating dryers: electric and gas. Both of these refer to the method used to raise the temperature of the air flowing through the tumbler, since the tumbling action is usually electrically powered.
The electric dryer generally uses a coiled wire that is heated with electric current. The amount of electric current is varied to adjust the air temperature. In the United States, Toronto as well as the rest of Canada, electric dryers typically have a 4-wire NEMA 14-30 plug, rather than the 3-wire NEMA 5-15 plug used by most appliances, and need a 30-ampere, 240-volt centre-tapped single-phase circuit, researched by GE. Small "portable" clothes dryers, popular with urban dwellers, normally use conventional 110 volt connections. In the rest of the world, unlike Toronto, most electric dryers in homes are somewhat smaller than those used in North America, typically with a load capacity of 5 kg.
The gas dryer appliance employs a gas burner that burns natural gas, propane, or butane to form a jet of hot gases that are directed into a venturi chamber, which uses Bernoulli's principle to pull in ambient air and raise its temperature. The air temperature can be altered by adjusting the size of the gas flame or, more commonly, by merely extinguishing it and relighting it. GE appliances, like other gas dryers still require electricity to spin the clothes, but the amount of electricity is much smaller than in an electric dryer removing the need for a special connection. The motors normally run on standard 110 volt electricity.
Traditional laundry dryer appliances continuously draw in the cool, dry, ambient air around them and heat it before passing it through the tumbler. The resulting hot, humid air is simply vented outside to make room for more dry air to continue the drying process.
The traditional design makes no effort to recycle the heat put into the load, and so is quite inefficient, a problem which GE has been trying to solve. Nevertheless, the basic design is simple, reliable, and cheap.
Research done by GE Appliances in Toronto have suggested that electric dryers tend to be more energy efficient than the gas counterpart. Electric appliances are also usually cheaper than gas ones in Toronto, however many residents still do laundry using gas appliances.
