Although shown and described, this invention is not limited to this. That is, in the present invention, any device capable of generating steam can be used as a steam generator. For example, it is possible to use a method in which a heater is directly provided around a water supply hose through which water is passed, that is, a method in which water is heated without containing water in a predetermined space (hereinafter referred to as "pipe heating method" for convenience).

Referring to Figure 4, another embodiment of the steam dryer according to the present invention will be described.

In this embodiment, the water supply source for supplying water to the steam generator 200 is removable. As in the previous embodiments, the water source may be a faucet, but in this case the installation is complex. This is because steam dryers usually do not use water, so when using a faucet as a water supply source, it is necessary to additionally install various devices. Therefore, as in the present embodiment, using a detachable water supply source (Detachable Water Supply Source) 300, the water supply source 300 is supplied to supply water, steam the water supply source 300 filled with water It is very convenient to connect to the water supply passage of the generator 200, that is, the water supply hose 220.
