At this time, the solar cell 10 is installed in an outdoors where sunlight is well irradiated and has a form in which a number of modules capable of sufficiently generating electric power necessary for driving the hot water heating device 30 are assembled into one module. The solar energy is continuously converted into electric energy in the daytime and supplied to the boiler drive unit 20 side.

When a high voltage is output from the boiler drive unit 20, the plurality of magnetrons 34 are driven to generate microwaves. The generated microwaves are supplied to the plurality of induction heating type heating pipes 35, Since the black carbonized silicon carbide powder 35d is heated by the hot water in the warming tank 40 flowing through the inside of the induction heating type heating pipes 35 in a predetermined temperature range, And the hot water heated by the principle of descending water having low temperature is automatically convected to the side of the warming tank 40.

At this time, the closed chamber 31 of the constituent elements of the hot water heating device 30 is formed into a cylindrical or polygonal shape having a predetermined diameter, length and volume by using a metal plate (for example, a stainless plate or the like) A plurality of magnetron mounting holes 31a are formed at predetermined intervals on the outer side of the chamber 31, and the upper and lower openings are closed to prevent microwave leakage.

The chamber 31 is further provided with a chamber pressure check valve 31c so that the air in the hollow portion 31b formed between the inner surface of the chamber 31 and the outer surface of the heat insulating case 32, The chamber pressure check valve 31c is automatically opened to lower the pressure in the chamber 31 when the chamber 31 is inflated to a predetermined pressure set on the pressure check valve 31c so that the chamber 31 is damaged or damaged by the expansion pressure, It is possible to prevent breakage.

In addition, at the entrance of the chamber pressure check valve 31c, a mesh net 31d having a mesh of 3 mm or less is installed to prevent microwaves from flowing out, thereby releasing internal air through the chamber pressure check valve 31c as described above It is possible to prevent the microwave diffracting the hollow portion 31b from being blocked by the mesh net 31d of mesh of 3 mm or less and to prevent the microwave from leaking to the outside, .

The heat insulating case 32 is formed to have a cylindrical or polygonal shape corresponding to the shape of the chamber 31 and has an outer diameter smaller than the inner diameter of the chamber 31, Type heating pipes 35 are embedded in the chamber 31 and then fixed in the chamber 31 through a plurality of supports 33 installed at regular intervals, And a hollow portion 31b having a predetermined height and a space area is formed between the inner surface of the heat insulating case 32 and the outer surface of the heat insulating case 32. [

The heat insulating case 32 having such a configuration is discharged through the waveguide 34a of the magnetron 34 and then passed through the induction heating type heating pipe 35 to be described later by a microwave diffracting in the hollow portion 31b And the heat generated in the induction heating type heating pipe 35 is not transmitted to the chamber 31, so that the temperature rise of the chamber 31 can be minimized.

The magnetrons 34 are basically used as a special vacuum tube for controlling the flow of electrons by applying a magnetic field to strongly output microwaves of microwaves. The magnetrons 34 Have a configuration in which an end of a waveguide 34a from which microwave is emitted is detachably attached to the magnetron mounting hole 31a of the chamber 31, respectively.

When a high voltage is applied from the high voltage transformer of the boiler drive unit 20, the magnetrons 34 oscillate high frequency to be supplied to the hollow portion 31b formed between the inner surface of the chamber 31 and the outer surface of the heat insulating case 32, (For example, 2,450 MHz / sec), the microwaves radiated from the magnetrons 34 are radiated from the hollow portion formed between the inner surface of the chamber 31 and the outer surface of the heat insulating case 32 31b and passes through the heat insulating case 32 to be described later to directly induction heat the black silicon carbide powder 35d in the induction heating type heating pipes 35 having the function of absorbing the magnetic field.

The end of the waveguide 34a is detachably attached to the magnetron mounting hole 31a of the chamber 31 as described above so that the magnetron 34 can be detached from the outside of the chamber 31 34) can be simply replaced.

On the other hand, the plurality of induction heating type heating pipes (35) are provided with inner, outer and intermediate tubes (35a) to (35c) formed of predetermined materials so as to have the same length as different diameters A silicon carbide powder 35d having a specific gravity of 3.12, a melting point of 2,600 to 2,800 ° C and a hardness higher than that of diamond is filled in the space portion formed between the outer surface of the inner tube 35a and the inner surface of the middle tube 35b And is disposed inside the heat insulating case 32 at a predetermined interval.

The plurality of induction heating type heating pipes 35 having the above-described configuration are arranged such that when microwaves of a predetermined band are emitted from the magnetrons 34 operated corresponding to the output signal of the boiler drive unit 20, The black silicon carbide powder 35d filled between the outer surface of the inner tube 35a and the inner surface of the intermediate tube 35b is heated by direct induction heating within a predetermined temperature range, And performs the function of continuing the natural convection to the side of the warming tank 40 by heating the water that has been packed or passed through the space formed between the outer surface of the pipe 35b and the outer pipe 35c with hot water.

At this time, the inner tube 35a of the triple tubes 35a to 35c of the induction heating type heating tube 35 may be a metal tube (for example, a stainless steel tube having a melting temperature of 1,400 ° C) or a glass tube The inner and outer tubes 35b and 35c are formed into a glass tube (for example, a glass tube having a melting temperature of 600 to 700 占 폚, And the black silicon carbide powder 35d, which is inductively heated by the microwaves emitted through the magnetrons 34, is formed at a temperature of 600 - When water is heated to less than 700 ° C, the triple tubes (35a) to (35c) constituting the induction heating type heating tube (35) are not melted at all and maintain their original shape, As well as the black silicon carbide powder 35d, The heat generated up to facilitate delivery to the water is water to be heated by continuously heating the water in the hot water continues to be line by natural convection toward the insulating tank (40).

In addition, the triple pipes 35a to 35c, which are manufactured in the form of a metal pipe or a glass pipe, can be freely formed in any shape, and the charging of the black silicon carbide powder 35d can be easily performed regardless of the shape of the triple pipe So that the induction heating type heating pipe 35 can be freely manufactured without being affected by the shape or the length. Particularly, since the surface is smooth, various kinds of waste materials, etc., It does not stick to the surfaces of the middle tubes (35a) - (35c) and can be used for a long time without cleaning or the like.

Further, in the present invention, the black silicon carbide raw material is melted and directly molded into a tubular shape to form a powder form of fine particles without being installed with the induction heating type heating pipe 35, so that the inside of the triple pipes 35a to 35c The microwaves of the predetermined band are emitted from the magnetrons 34 to be filled in the space between the outer surface of the tube 35a and the middle tube 35b so that the black silicon carbide powder 35d is discharged through the outer tube 35c, The amount of heat generated can be further increased as compared with the shape of a tube having no space between particles, and the power consumption can be greatly reduced.

That is, in the case of a tube formed by melting black silicon carbide, there is a fixed pore generated in the firing process, but there is no fluid pore. On the other hand, since the fine pores formed between the black silicon carbide powder of the fine particles are all fluid, Since the heating time of the microwave is very short and the heating time of the black silicon carbide powder particles is heated by the microwave, the fine particles contact with each other and generate sparks. Therefore, when the same power consumption is used, The amount of heat generated by the powdered black silicon carbide is further increased, and the power consumption can be greatly reduced.

In the present invention, in manufacturing the induction heating type heating pipe 35, as described above, three tubes 35a to 35c having the same length as those of different diameters are installed in triple at a predetermined interval Since the black carbon powder 35d is filled between the outer surface of the inner tube 35a and the inner surface of the middle tube 35b in the state of the black tube 35a, the microwaves emitted from the magnetrons 34 can be filled with black silicon carbide The powder 35d can be smoothly reached, and a desired heat generation amount can be accurately obtained.

In addition, since the water passing through the inner space of the inner tube 35a as well as the space formed between the outer surface of the middle tube 35b and the outer tube 35c is not in direct contact with the black silicon carbide powder 35d , The direct water in which the basic component is present is introduced into the induction heating type heating pipe 35. Even if chlorine (Cl ₂ ) is generated during the hot water heating, the water itself does not directly contact the black silicon carbide powder 35d, It is possible not only to completely prevent the induction heating type heating pipe 35 from being damaged by the Cl ₂ component but also to extend the service life of the induction heating type heating pipe 55 itself.

In the present invention, a ceramic heat insulating material (for example, a ceramic fiber or the like) having a function of passing microwaves and blocking heat emission outside the outer tube 35c of the induction heating type heating pipe 35, A heat insulating pipe 35e formed of a heat insulating material is further provided.

Therefore, the heat generated in the hot water heated by the heat generated in the black silicon carbide powder 35d, including the heat itself generated in the black silicon carbide powder 35d, Can be prevented from being discharged to the space in the heat insulating case 32 through the outer pipe 35c and the heating effect of the hot water using the heat generated from the black silicon carbide powder 35d can be greatly increased.

When the temperature of hot water rises above the set temperature or the boiling temperature stored in the hot water tank 30 It is possible to prevent unnecessary electric power consumption by preventing the magnetron 34 from being driven until the temperature of the magnetron 34 becomes lower than a predetermined temperature and then driving the magnetron 34 again or by changing the number of driving operations of the magnetron 34. In addition, It is possible to prevent the occurrence of safety accidents caused by the accident.

In addition, in the present invention, a steam pressure check valve 41a is additionally installed in the steam discharge pipe 41 so that the steam pressure generated in the warming tank 40 by the continuous hot water heating of the hot water heater 30 is lower than the vapor pressure check The steam pressure check valve 41a is automatically opened and the steam in the warming tank 40 can be discharged so that the steam pressure in the warming tank 40 becomes constant It is possible to prevent the explosion or the like of the warming-up tank itself due to the rise to the pressure or more.

At this time, the steam generated in the warming tank 40 due to continuous hot water heating by the hot water heating device 30 is discharged to the normal hot water heating device (not shown) 30, and then performs a secondary heating function on the hot water that is being dewatered in the hot water tank 40, thereby preventing the temperature of the hot water from falling.

Meanwhile, in the above description, when the pressure of the steam generated in the warming tank 40 is equal to or higher than the pressure set by the steam pressure check valve 41a, the internal pressure of the warming tank is maintained at a predetermined pressure or lower The steam generated automatically due to the continuous heating of the hot water through the hot water heater 30 provided with the magnetron 34 by using the solar photovoltaic voltage during the day is not simply discarded, It can also be used to generate electricity by supplying it to a steam generator turbine.
