Claims

[Claims for Utility Model Registration] (1) In an industrial microwave heating device that continuously dielectrically heats a large amount of processed material using microwaves, the oven is heated by microwave discharge in the oven or by ignition of the processed material. A microwave heating device characterized by being equipped with one or both of an ultraviolet sensor that detects ultraviolet light from a flame and an optical smoke sensor that detects smoke from a processed material. (2) The microwave heating device according to claim 1, wherein the ultraviolet sensor is installed at a position remote from the exhaust port of the oven. (3) The microwave heating device according to claim 1, wherein the optical smoke sensor is attached to a position near the exhaust port of the oven together with a flow plate that causes a vortex in the air flow. (4) The oven according to claim 1, characterized in that the inside of the oven is partitioned by walls that have excellent heat resistance, a small dielectric loss coefficient, and do not allow ultraviolet rays to pass through, and an ultraviolet sensor is installed in each section. Microwave heating device.
