In general, the liquid induction heating apparatus includes an induction coil and a liquid circulation tube and a liquid induction tube which surround the induction coil inside and outside and form a passage through which the liquid flows.

In the liquid induction heating device, when AC power is applied to the induction coil, the induction coil generates heat, and the liquid circulation tube and the liquid induction tube are heated based on the heat generation, resulting in a passage formed by the liquid circulation tube and the liquid induction tube. The flowing liquid is also heated. At this time, the AC power source may use a commercial AC power source (60 to 220V) of 60 Hz.

However, in such a conventional technique, since there is an extra space between the induction coil and the liquid circulation tube and the liquid induction tube surrounding the induction coil inside and outside, the heat of the induction coil is transferred to the liquid circulation tube and the liquid induction tube. There is a drawback that the efficiency of conduction is lowered, so that the heating efficiency of the liquid flowing through the passage formed by the liquid circulation pipe and the liquid induction pipe also decreases.

The present invention has been made in order to solve the above-mentioned problems, and the induction heating is filled with an insulator having a good thermal conductivity in the extra space between the liquid circulation tube and the liquid induction tube surrounding the induction coil inside and outside to form a passage through which the liquid flows. The purpose is to provide a liquid induction heating apparatus for increasing the thermal efficiency.
