Title:
MICROWAVE HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/074704
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to improve, relative to the power supplied to a microwave generator, the heating efficiency of an accommodating container to be microwave-heated, when a cavity resonator for microwave heating is excited in an excitation mode in which a magnetic field is concentrated on a central axis. The present disclosure is a microwave heating device 3, characterized in that: a cavity resonator 31 for microwave heating and an accommodating container 32 to be microwave-heated are provided; the cavity resonator 31 is excited in an excitation mode in which a magnetic field is concentrated on a central axis; the accommodating container 32 is disposed on the central axis of the cavity resonator 31; and the cavity resonator 31 has a slit formed in a side surface 311 in a direction parallel to the central axis.
