  • Patent number: 10443889
    Abstract: A super-high-efficiency induction hot water heater comprises: an external tank filled with water therein; an induction work coil provided in the center of the external tank; a plurality of internal tanks having walls formed from induction conductor heating plates, and into which water flows, and arranged around the induction work coil by being spaced from the induction work coil; an alternating current/direct current conversion unit receiving an alternating current and converting the same into a direct current; and a high frequency generation unit generating a high frequency by receiving the direct current of the alternating current/direct current conversion unit, and providing the high frequency to the induction work coil, and allowing the water filled inside the external tank and the water flowing inside the internal tanks to be heated when the induction conductor heating plates are heated by the induced high frequency current.
