Title:
MICROWAVE HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/004429
Kind Code:
A1
Abstract:
The purpose of the present disclosure is, in the use of microwaves to heat a heating target, to maintain the resonance frequency of a microwave heating device regardless of the inclination angle of an excitation loop relative to the magnetic field direction of a cavity resonator, and to reliably maintain matching between an input impedance of the microwave heating device and an output impedance of a microwave generator. The present disclosure comprises: an excitation loop 3 that is installed on the interior and a side wall of a cavity resonator 1, that excites the cavity resonator 1, and that has an inclination angle set relative to the magnetic field direction of the cavity resonator 1 so that the input impedance of a host device M will match an output impedance of a microwave generator; and a parasitic loop 4 that is installed on the interior and a side wall of the cavity resonator 1, that is not supplied with power, and that has an inclination angle set relative to the magnetic field direction of the cavity resonator 1 so that a resonance frequency of the host device M maintains a desired resonance frequency regardless of the inclination angle of the excitation loop 3 relative to the magnetic field direction of the cavity resonator 1.
