Heating tube assembly for high frequency induction heating electric boiler and high frequency induction heating electric boiler with same {A Heating Device and Induction Heating Boiler Having it}

The present invention relates to a high frequency induction heating electric boiler, and in particular, it is possible to store hot water and heating water in one heating tube so that it is possible to immediately supply hot water even without a separate hot water storage tank and supplement the heating water. Heating tube assembly for high frequency induction heating electric boilers, which makes it possible to automatically replenish the heating water without a separate device and to lower the pressure of the hot water storage supply automatically even without a separate pressure control device. And it relates to a high frequency induction heating electric boiler having the same.

A boiler is a device that burns fossil fuel such as petroleum, coal, and gas and transmits the heat of combustion to water to heat it. In recent years, the price continues to rise as resources such as petroleum and gas are gradually exhausted. Since there is a problem of environmental pollution due to the generation of various harmful gases in the burning process, in recent years electric boilers using electric energy has been widely used.

The electric boiler adopts a direct heating method in which a heating coil is disposed on the outer circumference of the heating tube, and heats the heating coil or the liquid in the heating tank by heating the heating coil by applying electrical energy to the heating coil. Electric boilers by coils take a long time to heat up, consumes a lot of power, and has a very complicated structure, such as an insulation structure for preventing heat generated from a heating coil from dissipating to the outside.

Accordingly, recently, an electric boiler using a high frequency induction heating method has been disclosed in order to overcome the disadvantages of a boiler and a direct heat type electric boiler using fossil fuel.

In this high frequency induction heating method, when a high frequency current is applied to the induction coil side, a high frequency magnetic field is generated on the induction coil side, and the high frequency magnetic field causes loss of eddy current (eddy current) generated in a heating tube made of a magnetic material or hysteresis loss. The heating box itself generates heat.

However, such a conventional high frequency induction heating electric boiler has the following problems.

First, in the case of an induction heating electric boiler combined with hot water for heating, a hot water storage tank, which is a separate auxiliary tank for supplying hot water in addition to the main induction heating device, is directly supplied with hot water.

Therefore, since a separate hot water tank must be provided, the installation time and cost are increased according to the installation of a separate hot water tank, and the product installation cost is increased, and the occupied space is increased according to the installation of a separate hot water tank.

Second, in the case of the heating water, the heating water in the main induction heating device evaporates over time. At this time, water must be replenished by the amount of heating water that evaporates. It had to be equipped.

As a result, it was pointed out that the increase of installation time and cost and the increase of occupancy of the installation space were required as separate heating water supplement tanks were provided.

Third, since the direct water supplied from the water supply pipe is supplied to the boiler, the pressure of the hot water is increased, and a separate pressure regulator is required to lower the pressure.

The present invention was created to solve the problems of the prior art as described above, and the purpose of the heating tube assembly for a high frequency induction heating electric boiler and the high frequency induction heating electric boiler having the same according to the present invention,

First, by allowing hot water and heating water to be stored in one heating container, hot water can be supplied immediately even without a separate hot water storage tank.

Second, even though there is no separate energy source, the hot water in the hot water storage supply automatically flows into the heating water storage unit through the first hot water gap and the second hot water gap due to the pressure difference, and thus a separate configuration for replenishing the heating water. Even without this, it is possible to automatically replenish the heating water in the heating water storage unit, and at the same time, it is possible to lower the pressure of the hot water storage supply unit without a separate pressure control device.

Third, by constructing a heating body of aluminum and forming a magnetic layer on the heating body by thermal spraying, it is possible to realize a heating container with excellent thermal conductivity, favorable for extrusion molding, corrosion-resistant and inexpensive. The present invention provides a heating tube assembly for a high frequency induction heating electric boiler and a high frequency induction heating electric boiler having the same.
