The present invention relates to a boiler apparatus, in particular, by providing a heat storage layer stabilization means to prevent the rise of the low-temperature heat medium and thus the heat storage layer deterioration, thereby significantly improving the quality characteristics of the boiler, and the assembly and disassembly of the high frequency induction heating unit is a heating casing. A heat storage layer stable high frequency induction heating boiler device which shortens the start-up heating time and dramatically improves the electric energy efficiency by utilizing the inner circumferential surface which is convenient in the closed state and is easy to repair and has the most thermal efficiency in the heating core for heating the medium. .

In general, fuel prices continue to rise along with depletion of fossil fuels such as diesel and gas, and the generation of harmful gases during operation causes environmental pollution. This technology uses electric energy for heating and heating devices such as boilers and hot air blowers. This research is a developing trend.

As an example of a heating heating device using electricity, when a high frequency current is applied to a coil, an induced current flows in a heating material in a high frequency magnetic field, and the induced current generates Joule heat due to loss caused by eddy current and hysteresis loss in the object. An induction heating apparatus of a high frequency heating method for heating a heat medium such as hot water or heating oil is disclosed.

As shown in Figure 6, the high-frequency induction heating boiler device, a high-frequency induction heating unit is installed in the heating outer cylinder 150, the high-frequency induction heating unit is installed in the induction coil 110 inside the insulating cylinder 120 The heating core 130 is wrapped around the insulating tube 120, and the heating medium to be heated is filled in the space S between the heating core 130 and the heating outer cylinder 150.

When a high frequency AC current is applied to the induction coil 110 by such a configuration, a high frequency magnetic field is generated, and the loss caused by the eddy current and the hysteresis loss in the heating core 130 installed with the insulating tube 120 interposed therebetween. Because Joule heat is generated, the heating core 130 surface temperature is rapidly increased, and the heating medium filled in the heating outer tube is heated, and the heated heating medium is supplied to the heating medium or domestic hot water through the water inlet 151, and the low temperature heating medium cooled by heating. The circulation is introduced again through the inlet 153.

On the other hand, in the heating cylinder 150, the heat storage layer is distributed differently depending on the height position. That is, the closer to the bottom of the heating outer cylinder 150, the lower the temperature, and the higher the temperature, the higher the inlet is arranged in the upper position where the high temperature heat medium is located.

However, in the prior art, there is a problem in that the heat storage layer in which the temperature difference is formed according to the water level is destabilized and deteriorated, thereby lowering the quality characteristics of the electric boiler.

It flows up by the return pressure of the pump when the low temperature heat medium inflows from the heating source through the inlet, and thus the heat storage layer array formed according to the temperature is broken, and the low temperature heat medium and the high temperature heat medium are mixed and the heat medium in the state below the set temperature is It is sent out as it is to reduce the heating efficiency.

In addition, the return port is located on the bottom side of the heating outer cylinder, the water inlet is disposed on the upper side wall of the heating outer cylinder, there is a problem such as cumbersome piping work.

On the other hand, the eddy current loss and hysteresis loss generated by the high frequency induction coil is generated on the inner circumferential surface of the heating core 130 facing the induction coil 110 (surface effect). That is, the rapid increase in the temperature of the heating core 130 is a result of heat generated by the entire body of heat generated on the inner circumferential surface facing the insulating tube.

However, in the prior art, since the inner circumferential surface of the heating core is installed in close contact with the insulator, the heating core is not in contact with the heating medium, which causes the heating to be most effective, thereby reducing the electrical energy efficiency and delaying the heating time.

The present invention has been made to solve the above problems,
