<p><P>PROBLEM TO BE SOLVED: To provide an instantaneous electric water heater which can be easy to handle and achieved at low cost without using a conventional heating exclusive heater. <P>SOLUTION: A power supply transformer comprised by winding a primary coil 12 applying commercial alternating current power around a center part edge 11a of an iron core 11, and winding a secondary coil 13 formed like a pipe by a flexible conductive material around the primary coil 12 is used as a water heater part body 1. The commercial alternating current power is applied to the primary coil 12 in a state of sending water through a pipe part of the secondary coil 13, and instantaneous heating of the water in the pipe part is carried out by heat generated by a secondary current generated by a secondary voltage induced in the secondary coil 13, and heat generated by a voltage conversion loss. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
