BEST MODE

(3) Hereinafter, the embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

(4) First of all, FIG. 1 is a diagram illustrating an embodiment of a super-high-efficiency induction hot water heater according to the present invention, wherein the super-high-efficiency induction hot water heater is configured to include an external tank 10, an induction work coil 20, first and second internal tanks 30 and 40, an alternating current/direct current conversion unit 50, and a high frequency generation unit 60.

(5) Such a configuration of the present invention will be described in detail with reference to FIG. 2.

(6) FIG. 2 is a diagram showing an embodiment of the first and second internal tanks 30 and 40 shown in FIG. 1.

(7) Referring to FIGS. 1 and 2, the external tank 10 may be filled with water and the induction work coil 20 may be provided at a center of the external tank 10.

(8) A plurality of internal tanks 30 and 40 may be provided such that walls thereof are formed as heat plates 31 and 41 of induction conductors and water flows inside the internal tanks. In addition, the internal tanks 30 and 40 may be arranged to have gaps with the induction work coil 20 around the induction work coil 20. In this case, the gap may be preferably less than or equal to 20 mm.

(9) In this embodiment, as shown in FIG. 2, the internal tank includes a plurality of partitions 110 having a small cross-sectional area than that of a passage of the respective internal tanks 30 and 40. In this case, the plurality of partitions 110 may be preferably installed in the passage of the internal tanks 30 and 40 in a zigzag to have space therebetween such that the water flows in a zigzag, thereby increasing the heating time of the water.

(10) In addition, the internal tanks 30 and 40 may be preferably formed in series by a number of tanks to increase the heating time of the water.

(11) Of course, two ways as mentioned above may be combined in order to further increase the heating time of the water.

(12) In addition, the induction work coil 20 may be configured such that multi-strand twisted copper wires are placed in a container having a thin, flat plane shape and then a vacant space of the container is filled with a liquid silicone insulator or urethane or epoxy insulators, in which surfaces of the container are waterproofed and insulated so as to normally operated in the water.

(13) The alternating current/direct current conversion unit 50 serves to convert alternating currents to direct currents. Herein, the alternating current voltage may be a 50 Hz to 60 Hz single- or three-phase voltage ranging from 110 V to 380 V.

(14) The high frequency generation unit 60 may generate high frequencies by receiving direct currents from the alternating current/direct current conversion unit 50 and output the high frequencies of 15 KHz to 75 KHz to the induction work coil 20 such that high frequency currents are inducted into the heat plates 31 and 41 of the induction conductors by the induction work coil 20 to heat the heat plates 31 and 41 of the induction conductors, which in turn heats the water filled in the external tank 10 and the water flowing in the internal tanks 30 and 40y. At this time, because the work inductive coil 20 may heat the water filled in the external tank 10 using high temperature (up to 180 C.) generated in itself, it is possible that the electrical energy can be converted into the heat energy without further losses.

(15) Accordingly, in a super-high-efficiency induction hot water heater according to the present invention, an induction work coil 20 is formed at a center within an external tank 10 filled with water on the inside, a plurality internal tanks 30 and 40 are formed such that walls thereof serve as heat plates 31 and 41 of induction conductors and water flows inside the internal tanks, the internal tanks being arranged to have gaps with the induction work coil 20 around the induction work coil 20, a high frequency current is applied to the induction work coil 20 to be inducted into the heat plates 31 and 41 of the induction conductors to heat the heat plates 31 and 41 of the induction conductors, and thus the water filled in the external tank 10 and the water flowing in the internal tanks 30 and 40 are heated. Therefore, the present invention provides an advantage in that the electrical energy may be converted into the heat energy without further losses and either of water for heating and water for hot water may be heated using a small amount of electric power.

(16) In addition, the water of the external tank 10 may be used as water for heating and the water of the internal tanks 30 and 40 may be used as the hot water. Accordingly, since the water for heating may be used to be thoroughly separated from the hot water, one or more of the plurality internal tanks 30 and 40 may be used to supply the hot water for drinking in a stable manner.

(17) Although the technical idea of the present invention is described in conjunction with the accompanying drawings, it is merely illustrated by way of a preferred embodiment of the present invention and not limited to the description of the present invention. In addition, various modifications and substitutions will be apparent to those skilled in the art without departing from the scope of the technical idea of the present invention.
