A device for induction heating containing at least one bifilar coil 9 located in the housing 16; remote control device 1, automatic switch 2, temperature relay 3, voltage regulator 4, step-up transformer 5, diode 6, control module 7, power unit 8, quadrofilar coil 10, at least two non-polar capacitors 11, 15, transformer-output coil 13, at least one heating element 12, temperature sensor 14. Remote control device 1 is connected in series with automatic switch 2, temperature relay 3, voltage regulator 4 and control module 7. Automatic switch 2 is connected to remote control device 1 and temperature relay 3 Temperature relay C is connected to automatic switch 2, voltage regulator 4 and control module 7. Voltage regulator 4 is connected to temperature relay 3, remote control device 1 and control module 7. Control module 7 is connected to voltage regulator 4 , remote control device 1, temperature relay З and power unit 8. Power unit 8 is connected to control module 7 and bifilar k by tushko 9, which

Zo is placed parallel to the quadfilar coil 10. The quadrafilar coil 10 is connected to the first non-polar capacitor 11, the second non-polar capacitor 15, to the diode 6, the output coil transformer 13 and the step-up transformer 5.

The heating element 12 is connected to the output coil transformer 13 and the temperature sensor 14.

A device for induction heating, containing located in the housing 16 at least one bifilar coil 9; remote control device 1, automatic switch 2, temperature relay 3, voltage regulator 4, step-up transformer 5, diode 6, control module 7, power unit 8, quadrofilar coil 10, at least two non-polar capacitors 11, 15, transformer-output coil 13, at least one heating element 12, the temperature sensor 14 works as follows. When the remote control 1 is turned on, the voltage passes through the on circuit breaker 2 and goes to the temperature relay 3, which has temperature settings (lower on and upper off). The temperature sensor 14 monitors the heating element 12 (for example, a water tank) and transmits it to the temperature relay 3. The temperature relay C receives the signal from the temperature sensor 14 and turns on the voltage when the temperature is set lower. If the temperature of the heating element 12 rises to the upper set temperature indicator, then the temperature sensor 14 transmits a pulse signal to the temperature relay 3, which turns off the voltage.

Also, after turning on the temperature relay C, the voltage enters the control module 7, which turns on the power unit 8. The power unit 8 begins to generate a high-frequency voltage, which enters the bifilar coil 9. The bifilar coil 9 converts the high-frequency voltage into vortex-induced magnetic fluxes and transmits them on the quadfilar coil 10. The quadfilar coil 10 receives the vortex induced magnetic fluxes transmitted by the bifilar coil 9 and converts them into a reactive-active voltage. After the transformation, the reactive-active voltage enters the output coil transformer 13, through the first non-polar capacitor 11, where fluctuations and voltage amplification occur. After the transformation of the reactive-active voltage to a higher side, the reactive-active voltage enters the heating element 12 (for example, a water tank) and is transformed into thermal energy.

After switching on the temperature relay 3, the voltage also goes to the voltage regulator 4, because it regulates the active voltage both to the lower mark and to the upper one. The active voltage adjusted by the voltage regulator 4 enters the step-up transformer 5 and passes through the second non-polar capacitor 15, where fluctuations in the active voltage occur. After the second non-polar capacitor 15, the active voltage in an increased or reduced state enters the output coil transformer 13 through diode 6, which passes the active voltage in only one direction.

The circuit breaker 2 is designed to provide forced disconnection of the electrical circuit from the electrical network (not shown in the drawing) in the event of an abnormal state of the electrical circuit, such as excessive heating of the wires or a short circuit, also the circuit breaker 2 can be used as a switch of the device to the network.
