Abstract
Electrode elements directly heat water and with an electric current controller that is controlled by the heated water volume, which structurally enables immediate production of high temperature steam. The innovations of the invention here include: the utilization of an electric current controller than can be set at a certain value so that an electromagnetic water input valve is switched on or off at an appropriate time, which permits the maintaining of a fixed volume of water inside the water container and as such, the water inside the water container is not only prevented from overflowing, but at the same time forms an electric field with the electrode elements and is subsequently directly heated and thereby enables the production of high temperature steam in an extremely short period of time. Furthermore, the steam output port is designed with a pressure relief valve and a flow adjustment valve such that the high temperature steam produced rapidly escapes or is released in large volume safely and stably, which effectively ensures greater ease, convenience, multifunctionality and safety.
