The disk is rotatably supported via a bearing to form a rotor.
A plurality of heating coils are arranged and equipped in the circumferential direction of the conductive disk in close proximity to the conductive disk to function as a stator and a winding, and the power supplied to the heating coils is obtained by rectifying commercial power. A part of the output is generated by a control device, which converts the output into two-phase high-frequency waves with different phases, and supplies the two-phase high-frequency outputs as respective control signals to multiple resonant circuits that supply each heating coil. This is an induction electromagnetic wave heater that generates a high-frequency current in the heating coil and sequentially supplies it to the heating coil in order of phase to heat a rotating conductive disk once and blow air. (Example) Fig. 1 is a schematic perspective view for explaining the present invention in detail. I, 2, 3. 4 are two-phase high frequency heating coils, which are fixedly attached to the heater. 5 is a conductive It is a changing plate and is rotatably supported in the vicinity of the induction heating coils 1, 2, 3.4 of the heater.The conductive disk has slits 6 for ventilation, and 7 is blades for blowing air.

First, the high-frequency output of the control device 10 is applied to the induction heating coil 1 including a resonant circuit, and eddy current is generated in the vicinity of the conductive disk, generating heat due to the magnetic lines of force and the eddy current.

As in the case of the induction heating coil 1 supplied to the conductive disk, heat is generated by magnetic lines of force and eddy currents in the conductive disk. Similarly, the induction heating coil 3 is also supplied with a high frequency output whose phase is further delayed by 90 degrees. Then, a high frequency output with a phase delay of 90 degrees is further supplied to the induction heating coil 4. By sequentially supplying high frequency output to each induction heating coil in this way, the conductive disk generates heat as a heater.

The difference between this heater and a disk-type induction motor is that the disk-type induction motor has a low frequency of 50Hz and a high frequency of 20Hz that is supplied to the induction heating coil of the heater.
KHz difference and 50 for electric fans using induction motors.
It rotates at about W, but in the case of an induction heater, there is a difference in that it supplies about IKW of power to generate heat.

The device sucks out the hot air around the conductive disk, which is generated by eddy currents, forward. Furthermore, since the heating rotary body is a heat generating body, it is of course necessary to provide ventilating protectors at the rear of the induction heating coils 1 to 4 and at the front of the conductive disk.

This output is supplied to a flip-flop 15 via a diode 12, and a signal with a 180 degree phase delay is supplied to a flip-flop 6 via a series-connected diode I3 and an inverter 14. The frequency is divided by 1/2 and two signals having a phase difference of 180 degrees are output as the b signal and the C signal shown in FIG. As a result, the four output signals of the flip-flops 15 and 16 are output with a phase shift of 90 degrees. First, it is supplied from the flip-flop 15 to the 5CR17 to cause the heating induction coil to resonate. This resonance signal is the signal f in FIG. Next, flip-flop 16 to 5CR21 to 9

一少をきたす。Next, item 2 of the patent claim will be explained. The smaller the distance between the induction heating coil and the conductive disk, the greater the eddy current generation, but when mass producing a fixed induction heating coil and a rotating conductive disk, it is better to have a certain distance between them. It's easy to do. As a result, some eddy currents occur.

なくなる。To compensate for this, two conductive disks can be rotatably supported before and after the induction heating coil, with the front conductive disk having a ventilation structure and the back conductive disk having an air intake structure. . In this case, if the distance between the two conductive disks is too narrow, the magnetic field caused by the induction heating coil and the magnetic field caused by the eddy current cancel each other out, resulting in no effect.

In the induction heating heating method of the present invention, heating is performed with a power of about 600W=1200W, and the rotation only requires torque sufficient to simply rotate the blower blades. For electric fans, etc., power of about 50W is usually sufficient.

加熱型暖房方式。[Scope of Claims] 1. A plurality of ventilation slits and ventilation blades are provided in the conductive disk from the center to the outer periphery, and the conductive disk is rotatable so as to suck out and blow air from the rear of the conductive disk. A conductive disk is pivotally supported so that the conductive disk is rotated, and a plurality of flat induction heating coils are mounted facing each other with a small distance from the conductive disk along the rotational direction of the conductive disk. Two-phase high-frequency signals with different phases and equal frequencies are supplied to the coils in the order of the phases of the positive voltages of the plurality of induction heating coils, and the lines of magnetic force of the induction heating coils are sequentially generated in the circumferential direction to form a rotating magnetic field. The conductive disk is rotated by the magnetic field caused by the eddy current induced in the conductive disk by the magnetic field lines and the torque generated by the magnetic field of the induction heating coil, and the hot air around the conductive disk generated by the eddy current is heated. An induction heating type heating system characterized by blowing air. 2. In the induction heating type heating method described in item 1, if the distance between the induction heating coil and the conductive disk is wide and the generation of eddy current is weak, the two conductive disks can be freely rotated in front and behind the induction heating coil. This induction heating type heating system is characterized by improving the efficiency of eddy current induced heat generation by supporting the shaft and using the rear conductive disc as an intake vane. 3. Equipped with a generator so that the generator rotates on the rotating shaft of the conductive disk of the induction heating type heating method in Items 1 and 2,
An induction heating type heating system characterized by converting the electric power generated by the generator into two-phase high frequency and returning it to an induction heating coil to save power.
