Description

[Detailed explanation of the idea] The present invention relates to a steam iron.

In a steam iron, a vaporizing chamber is installed in a base that has a heating element, water is dripped into this vaporizing chamber from a dripping valve of a tank, and this water is instantly turned into steam, which is used as the steam outlet force of the base). Many are used that eject from the water.

However, this type of iron is susceptible to evaporation residue such as water scale, especially in the vaporization chamber, which causes gamma buildup and clogged holes in the drip valve, which can easily cause malfunctions, and the entire iron is damaged each time. This has the disadvantage that it must be disassembled and cleaned, and this disassembly and assembly is troublesome and difficult for ordinary users.
