HEATING DEVICE FOR TRACKING RESONANCE FREQUENCY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18238396 titled 'HEATING DEVICE FOR TRACKING RESONANCE FREQUENCY
Simplified Explanation
The abstract describes a heating device that uses a resonance frequency to heat a cooking appliance. The device includes a heating coil, a parallel resonance circuit, an inverter unit, a current sensor, and a processor.
- The heating device uses a heating coil to heat a cooking appliance.
- It includes a parallel resonance circuit that consists of an inductor (which includes the heating coil) and a resonance capacitor.
- An inverter unit supplies power to the parallel resonance circuit.
- A first current sensor detects the output current supplied from the inverter unit to the parallel resonance circuit.
- A processor controls the driving frequency of the inverter unit to ensure that the peak value of the output current is smaller than a predetermined threshold value.
Potential applications of this technology:
- This heating device can be used in various cooking appliances such as stoves, ovens, and induction cooktops.
- It can also be applied in industrial heating processes that require precise control of heating elements.
Problems solved by this technology:
- The device ensures that the output current supplied to the heating coil remains within a safe range by controlling the driving frequency of the inverter unit.
- By monitoring and adjusting the output current, the device prevents overheating and potential damage to the cooking appliance.
Benefits of this technology:
- The heating device provides efficient and precise heating control.
- It helps to prevent overheating and potential damage to the cooking appliance.
- The device ensures the safety of the user by maintaining the output current within a predetermined threshold value.
Original Abstract Submitted
A heating device for tracking a resonance frequency includes a heating coil for heating a cooking appliance, a parallel resonance circuit including an inductor including the heating coil and a resonance capacitor resonating with the inductor, an inverter unit for supplying power to the parallel resonance circuit, a first current sensor for detecting an output current supplied from the inverter unit to the parallel resonance circuit, and a processor for controlling a driving frequency of the inverter unit so that a peak value of the output current detected by the first current sensor is smaller than a predetermined first threshold value.
