[0002] A clothes dryer is a type of household cleaning appliance that uses electric heating to instantly evaporate and dry the moisture in washed clothes. It is particularly needed in the winter in the north and during the "returning south day" in the south when it is difficult to dry clothes. In addition, clothes dryers are widely used in industrial production to dry fabrics and improve production efficiency. Generally, a clothes dryer refers to a household-type simple clothes dryer, which mainly consists of a bracket, a main body, and an outer cover. Its characteristics are moderate price, easy to use, low failure rate, and suitable for ordinary families, students, and mobile groups. A clothes dryer uses high-temperature air flow to pass over the surface of the clothes to be dried, heats the clothes, and takes away the evaporated moisture to quickly dry the clothes. The common heating methods include electric heating wire heating and semiconductor (PTC) heating. The heater made of semiconductors will automatically reduce power in the environment (inside or around the clothes dryer), saving energy while also controlling the maximum temperature to protect the clothes, which is safe and reliable. It is not restricted by weather conditions. In addition, some clothes dryers with novel designs are easily disassembled, convenient, and space-saving. Most well-designed clothes dryers can be used for heating, serving multiple purposes, bringing a lot of convenience to families, and are effective equipment for reducing large-scale drying yards and providing drying at any time. To remove the peculiar smell on the dried clothes, some clothes dryers are provided with a fragrance agent storage device.
