A cleaning appliance that uses electric heating to iron clothes. It is one of the indispensable electrical appliances in modern families. It is a tool for leveling clothes and fabrics. The power is generally between 300-1000W. Its types can be divided into: ordinary type, temperature-regulating type, steam type, neat spray type, etc. Steam irons are made using the thermal effect of electric current and used for ironing clothes. In 1882, H.W. Sealy obtained the first patent for steam iron. At the beginning of the 20th century, the steam iron invented by E. Richardson of the United States was put on the market and was welcomed. The steam iron is simple in structure, easy to manufacture, and convenient to use, so it develops rapidly. There are two types of steam irons that are produced and used more frequently in my country, the ordinary type and the ordinary temperature-regulating type. Steam irons have also appeared in new varieties such as jet type, spray type, constant temperature type and electrolytic steam type. High power, light weight, automatic temperature adjustment, steam injection or spraying, and the pursuit of beautiful appearance is the development direction of the new generation of steam irons.
