What is Tumble dryers?

Views: 0     Author: Site Editor     Publish Time: 2023-05-26      Origin: Site

A tumble dryer or simply a dryer, is a powered household appliance that is used to remove moisture bedding, and other textiles.Many dryers consist of a rotating drum called a "tumbler" through which heated air is circulated to evaporate moisture while the drum rotates to maintain air space between items.Using such a machine may cause the garment to shrink or become less soft (due to loss of short soft fibers).A simpler type of non-rotating machine called a "drying cabinet" can be used for delicate fabrics and other items that are not suitable for a tumble dryer. Other machines include steam to shrink clothes and avoid ironing.

A tumble dryer continuously draws in ambient air around it and heats it before passing it through the tumbler.The resulting hot, humid air is usually vented outside to make room for more air to continue the drying process.A tumble dryer is sometimes integrated with a machine,in the form of a washer-dryer, which is essentially a front-load washer with an integrated dryer that stacks the dryer on top of the washer top and integrate the controls into one control panel.Dryers usually have different capacities for their functions, with dryers usually having a lower capacity than machines.Tumble dryers can also be top-loading, where the drum is loaded from the top of the machine,with the end supports for the drum positioned on the left and right sides, rather than the more traditional front and rear.They can be as thin as 40 cm (16 in) wide and may include removable holders for drying items such as stuffed animals and footwear.

Static electricity

Dryers cause electrostatic cling through the triboelectric effect.This can be a minor nuisance and is usually a symptom of textiles being overdried to very low humidity levels.Fabric conditioners and dryer sheets are also sold to remedy the situation, but some consumers want to avoid treating their chemicals.Modern dryers often have improved temperature and humidity sensors and electronic controls to avoid over-drying and the resulting static electricity and energy waste.

Drying at a high temperature of at least 60 °C (140 °F) for 30 minutes kills many parasites, including house dust mites,bedbugs and sarcoptic mites and their eggs; more than ten minutes A little will kill ticks.Simply washing will drown the dust mites, and three hours in direct sunlight will kill the dust mite eggs.


Dryers heat flammable materials.Underwriters Laboratories recommends cleaning lint filters after each cycle to ensure safety and energy efficiency, provide adequate ventilation, and regularly clean the ducts.UL also advises against using dryers on fiberglass, rubber, foam, or plastic items, or anything that has been sprinkled with flammable substances.In the United States, a 2012 report by the National Fire Administration estimated that from 2008 to 2010, fire departments across the country responded to approximately 2,900 residential building clothes dryer fires each year.These fires cause an average of 5 deaths, 100 injuries and $35 million in property damage each year.The fire department attributes “failure to clean” (34%) as the leading cause of dryer fires in residential buildings and observes a new residential construction trend to place dryers and washers in more dangerous locations away from exterior walls such as in bedrooms, second floor hallways, bathrooms and kitchens.To address dryer fires, fire suppression systems can be used with sensors to detect temperature changes in the dryer drum when a fire starts.These sensors then activate a water vapor mechanism to extinguish the fire.
