About Tumble Dryers
The tumble dryer is a domestic electrical appliance which removes moisture from clothes. The machines generally work by circulating hot air through a rotating drum. The first tumble dryer was released in 1938 and designed by J Ross Moore in America, although it wasn't until the 1940s that the first electric tumble dryer complete with glass window was manufactured.
The main distinction between tumble dryers is the way in which moisture is vented from the drum, thus giving us the option of 'vented' or 'condensing' machines.
Vented tumble dryers.
The vented tumble dryer, or traditional tumble dryer is simple in its mechanism. The machine draws in cool air and heats it before circulating the air around the drum, drying the clothes. The moist, warm air drawn from the drum is then extracted through a vent that is usually fitted to an exterior wall, therefore allowing the 'used' air to be exhausted outside. Because the warm air isn't recycled in any way, vented tumble dryers are considered more impactful on the environment, however they remain the most popular choice in many households worldwide.
Condensing tumble dryers.
Condensing tumble dryers work similarly to vented dryers, however instead of the heat being exhausted outside via a vent, the moisture from the 'used' air is condensed and collected in a tray to be emptied periodically by the user. The newly dry air is then recirculated and the process begins again. Although they are considered better for the environment than vented dryers, they do use up to 15% more energy.
Today there are many different types of tumble dryer; including environmentally friendly options and various sizes to suit any kind of 21st century home, allowing us versatility when designing kitchens and utility rooms.
