INDUCTION HEATING TYPE LIQUID HEATER AND INDUCTION HEATING TYPE LIQUID HEATING APPARATUS

摘要

PROBLEM TO BE SOLVED: To improve heating efficiency by enlarging the surface area of a heat generator.;SOLUTION: A heat generation coil that is spirally wound is inserted to a pipe. A liquid channel is disposed between the pipe and the heat generation coil. An induction coil is spirally wound on the outer circumference of the pipe. A heat-generation coil in the pipe generates heat according to induction heating when a high-frequency current flows through an induction coil, and liquid in the liquid channel is heated. Two or more heat-generation coils may be inserted concentrically to the pipe, or one long heat generation coil may be disposed in the pipe while being folded a plurality of times at both axial end parts of the pipe. A liquid inlet is disposed on one axial end of the pipe, and a liquid outlet is disposed on the other end. The liquid inlet and the liquid outlet lead to the liquid channel in the pipe to heat the liquid supplied from the liquid inlet while the liquid is output from the liquid outlet.;COPYRIGHT: (C)2013,JPO&INPIT
