The present invention relates to a heating device for heating and steam, and more particularly, to a conductor having a cup-shaped cross-section with an open top, the outer circumferential surface of which is built in non-contact to generate a current when power is applied. It is composed of a reheating member for preventing short circuit that is provided in a non-contact with the current generating unit by being coupled to the conductor, and instantaneously heating water with the current generated by the current generating unit without short circuit by the reheating member for preventing ground leakage. The present invention relates to a heating device for heating and steam that enables instantaneous heating of water with low power.

In general, an electric boiler is a boiler that uses heat generated from electricity instead of fuel.

In terms of type, these electric boilers are an electrode type that generates Joule heat through an electric current between electrodes using water itself, which is boiler water, as an electrical resistor, and a metal resistance wire is put directly or indirectly into water, which is boiler water. Although there is a resistance type or a hot wire type using heat generation, an electrode type is generally used.

The above-described electric boiler has a simple structure, is hygienic, has a low risk of accidents such as overheating, and is highly efficient.

A small amount is used in places where environmental hygiene is particularly strict, such as hospitals.

Conventional electric boilers heat water by putting electrode rods in water, which is usually a heating object. At this time, the power used usually ranges from several to tens of KW depending on the amount of hot water supplied, so electricity to which the progressive tax is applied is used for general households and business purposes, except for industrial use, to which the progressive tax is not applied, so the efficiency is relatively low compared to the electricity rate.

In consideration of this point, an electrode heater for an electric boiler has been proposed in Patent Application No. 10-2016-0032762.

Looking at the conventional electrode heater for an electric boiler, a first conductor with an open upper portion and a first through hole formed at the lower portion, an upper portion open and a second through hole formed at the lower portion, and a constant portion on the side and the lower portion of the first conductor The second conductor installed at a distance and the first upper protrusion protruding upward pass through the second through hole of the second conductor and are coupled to the coupling member through the first through hole of the first conductor and protrude downward The first electrode to which the first power terminal is coupled and the third through hole coincident with the second through hole of the second conductor are formed between the nut fastened to the first lower protrusion, and a fixing hole is formed on one side, and the top surface is A second power terminal is inserted between the electrode bar fixed in contact with the bottom surface of the second conductor, and a nut having a second upper protrusion protruding upwards fixedly coupled to a fixing hole of the electrode bar and fastened to a second lower protrusion protruding downward. A second electrode coupled thereto, a first insulator having a thickness of 10 mm in which the first upper protrusion of the first electrode is through-coupled between the lower surface of the first conductor and the upper surface of the second conductor, and the third through hole and the second through hole of the electrode bar A second insulator coupled between the first electrodes, a third insulator coated on the outer periphery of the first electrode body, and a fourth insulator coated on the outer periphery of the second electrode body, wherein the first conductor and the second insulator The second conductor is installed in the hot water pipe or the heating water pipe in the boiler, and the first electrode and the second electrode are fixedly coupled to the flange formed in the through hole formed through the outer surface of the hot water pipe or the heating water pipe by a fixing member, and the power terminal is respectively connected and the potential difference between the power applied to the first conductor through the first electrode and the power applied to the second conductor through the second electrode is generated between the outer circumferential surface of the first conductor and the inner circumferential surface of the second conductor. It consists in heating water by arc discharge.

However, in the conventional electrode heater for an electric boiler configured as described above, as described above, when power is applied through the first electrode and the second electrode, there is an arc between the outer peripheral surface of the first conductor and the inner peripheral surface of the second conductor. (Arc) Discharge is generated and high-temperature heat is generated by thermal ionization to heat water, which is boiler water, which is a medium resistance. There is a disadvantage in that arc discharge efficiency is inevitably lower than that of the applied power.

In addition, in the conventional general electrode heater for an electric boiler, the first conductor and the second conductor are exposed, so it is not possible to suppress the resistance due to the eddy current generated when the water, which is boiler water, is introduced. There is a disadvantage in that the heating efficiency is inevitably lowered.
