ABSTRACT:
A microwave baking furnace is provided including a metallic cavity irradiated with microwaves; a baking chamber provided in the cavity and surrounded by a heat insulating member having a low microwave absorption characteristic and a high heat insulating property, which is disposed in the cavity; and a microwave generator. Substances having a high microwave loss are arranged in weak microwave electric field areas in the baking chamber at a distance, which exceeds ¼λ of a wavelength λ of microwaves to be used, from the metallic cavity. The microwave baking furnace can efficiently implement a temperature rise in a low temperature range and a temperature rise in a high temperature range only by microwave heating, can effectively prevent the occurrence of a temperature gradient in an object to be baked during a baking process, and is stable in supply of microwaves and is simply structured.
