WATER HEATER WITH HIGH FREQUENCY ELECTROMAGNETIC HEATING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric water heater solving the problems that heating efficiency is low, life of a sheath heater is short, and a risk of electric leakage is high.SOLUTION: A water heater with a high frequency electromagnetic heating device generates electromagnetic induction in a spiral heating coil 2, and simultaneously heats and magnetizes water flowing inside a columnar electromagnetic induction material heating device body 1 adjacent to the spiral heating coil 2 and inside a hollow columnar electromagnetic induction tub 3.
