1 is a structural diagram of a boiler apparatus using high frequency induction heating according to the present invention.

As shown, the boiler 10 of the present invention includes a rectangular main body 11 filled with heating water, and the first heating chamber 13 and the second heating chamber 14 are located at the inner center of the main body 11. The diaphragm 12 is installed, and the upper portion of the diaphragm 12 is configured to open a predetermined portion so that the heating water flows to the first heating chamber 13 and the second heating chamber 14.

The heating receiving water pipe 16 is formed on the bottom of the first heating chamber 13, and the heating import water pipe 15 is formed on the side surface of the second heating chamber 14 so that the heating water is the heating import water pipe 15. Through the heating pipe 17 flows through, and the heating water via the heating pipe 17 is formed in a structure that flows into the heating water return pipe 16 through the circulation pump 18.

In addition, in the first and second heating chambers 13 and 14, a pair of induction heating apparatuses 20 and 40 and heating members 30 and 50, which are heating devices for raising the temperature of heating water, are respectively paired. Is formed.

The induction heating apparatus (20, 40) is a cylindrical insulating tube 21, 41 formed with induction coils 22, 42 therein and a predetermined interval outside the insulating tube (21, 41). It consists of cylindrical heating tubes 23, 43 which are placed and installed.

Looking at the heating principle of the induction heating device 20, 40 configured as described above, when a voltage having a predetermined frequency (20 ~ 25KHz) is applied to the induction coil (22) 42, the induced electromotive force is generated in this coil The electromotive force excites the heating tubes 22 and 42 provided at regular intervals from the insulating tubes 21 and 41, thereby rapidly increasing the temperature around the heating tubes 22 and 42. .

In addition, the heating member 30, 50 is installed to surround the outside of the induction heating apparatus 20, 40, respectively, a cylindrical shape and made of a conductive material, a kind of self-heating in proportion to the applied voltage It is a heating member that performs the same function as the heater.

In addition, the boiler 10 is further provided with a hot water pipe (40).

Looking at the installation structure of the hot water pipe 40, the hot water pipe 60 flowing into the first heating chamber 13 of the main body 11 is the heating tube 23 and the heating member of the induction heating device 20 ( After being installed to wrap in a spring shape in the space between 30, it is configured to lead to the second heating chamber 14 through the opening formed in the partition wall 12.

The hot water pipe 60 introduced into the second heating chamber 14 has the same structure as above, so as to surround the spring tube in a space between the heating tube 43 and the heating member 50 of the induction heating apparatus 40. After the installation, it is configured to be connected to the hot water faucet through one side of the second heating chamber 14, the hot water pipe 60 is further provided with a water flow sensor 70 for detecting the flow of hot water.

Here, the spring structure of the installation structure of the hot water pipe 60 is to increase the water temperature more efficiently by increasing the surface area of the pipe.

The operating principle of the boiler 10 of the present invention configured as described above will be described by dividing into heating and using hot water.

First, in heating, power is applied to the induction heating apparatus 20, 40 and the heating member 30, 50 to increase the temperature of the heating water.

Therefore, the surface temperature of the heating tubes 23 and 43 rises rapidly by the induction heating of the induction heating apparatuses 20 and 40, and at the same time, the induction heating apparatus 20 is generated by the heating of the heating members 30 and 50. The temperature of the heating water in the space between the 40 and the heating members 30 and 50 rises rapidly. The heating water that has risen sharply increases the temperature of the heating water of the first and second heating chambers 13 and 14, and the heating water of the second heating chamber 14 is heated through the heating import pipe 15. Flow to the heating pipe 17 to perform the heating action and again to obtain the first heating chamber 13 through the heating and return pipe (16).

On the other hand, look at the use of hot water, when the user opens the faucet in order to use the hot water flow sensor 70 detects this to start the boiler drive according to the use of hot water. Therefore, the hot water flowing into the hot water pipe 60 is primarily the water temperature rises while flowing through the hot water pipe located in the first heating chamber (13). And while flowing to the hot water pipe located in the second heating chamber 14, the water temperature further rises.

As a result, the hot water has an effect of raising the water temperature very quickly through two heating processes. In this way, the hot water whose temperature is raised is discharged to the faucet through the flow sensor 50.

According to the present invention, the diaphragm 12 formed in the inner center of the main body 11 is a very important component, which is introduced into the first heating chamber 13 through the heating and return pipe 16 during the heating operation of the boiler. The return water (low water temperature) is a means for excluding the phenomenon of directly exiting the heating water inlet pipe 15. Therefore, the heating water drawn in through the heating water return pipe 16 in the configuration of the diaphragm 12 is the water temperature is increased through the upper opening of the diaphragm 12 after the water temperature is first increased in the first heating chamber 13. The heating water is introduced into the second heating chamber 14, and the heating water discharged from the second heating chamber 14 to the heating intake pipe 15 is maintained at a high temperature due to the water temperature rising by the heating action once again. Will be.

In addition, the setting unit 100 is further provided with an operation start and end setting switch 101 that can be set to reserve the operation start time and stop time of the boiler. Therefore, when the user sets the operation start time and the operation end time by operating the operation start and end setting switch 101, the boiler performs the driving operation of the boiler only during the set time.

The circuit operation of the boiler 10 of the present invention configured as described above will be described with reference to the control flowchart of FIG. 3.

First, the control unit 130 detects a signal input through the temperature sensing unit 110 to recognize the current room temperature (step S10).

In addition, the controller 130 compares the temperature already set by the setting unit 100 with the current room temperature (S11). If the current temperature is higher than the set temperature, the controller 130 stops the output to the high frequency oscillation driver 80, the heating member driver 90, and the pump driver 120 to heat the induction heating apparatus 20, 40, and the heating unit. The driving of the members 30 and 50 and the circulation pump 18 is stopped (step S12).

If the current temperature is less than the set temperature in the determination step (S11), the control unit 130 performs a drive output to the high frequency oscillation driving unit 80, the heating member driving unit 90 and the pump driving unit 120 (step S13). .

Therefore, the high frequency oscillation driving unit 80 drives the induction heating devices 20 and 40, the heating member driving unit 90 drives the heating members 30 and 50, and the circulation pump driving unit 120 rotates. The pump 18 is driven. As a result, the boiler's heating water begins to heat up.

In addition, the controller 130 detects a value input through the water flow detector 70 to determine whether hot water is currently used (step S14).

When the use of hot water is detected in the determination step (S14), the flow returns to the step (S13) to start the boiler by performing a drive output to the high frequency oscillation driving unit 80, the heating member driving unit 90 and the pump driving unit 110. It is to let.

However, if you do not use hot water, the program returns.
