## Abstract

The present invention relates to a steam generation device for automatic water supply using self vapor pressure that continuously generates necessary steam while smoothly supplying water to a steam tank by using a self vapor pressure stored in the steam tank as well as minimizes heat loss in a process of generating steam to outside thereby reducing energy consumed in generating steam, and more particularly, to a steam generation device for automatic water supply using self vapor pressure that supplies water more smoothly through a control method of opening a water supply pressure tank only after the water supply pressure tank is supplied with sufficient vapor pressure.

## Claims
