Title:
MICROWAVE HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/004428
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to uniformly heat a microwave heating target by uniformly distributing the microwave magnetic field or the microwave electric field near the center axis of a cavity resonator, when heating a heating target by using microwaves. The present disclosure is a microwave heating device M equipped with: a cavity resonator 1 for concentrating the microwave magnetic field or the microwave electric field on the center axis; a storage container 2 for storing the microwave heating target on the center axis of the cavity resonator 1; and two excitation loops 3 which are positioned at 90-degree intervals from one another inside the cavity resonator 1 or on a lateral wall thereof, and in which adjacent targets are excited at a phase difference of 90 degrees, or n number of excitation loops 3 (n is 3 or higher) which are positioned at n/360 degrees from one another inside the cavity resonator 1 or on the lateral wall thereof, and in which adjacent targets are excited at a phase difference of n/360 degrees. Said microwave heating device M is characterized in that the microwave magnetic field distribution or microwave electric field distribution rotates around the center axis of the cavity resonator 1 as time passes.
