<p><P>PROBLEM TO BE SOLVED: To provide a microwave heating device providing whole uniform heating with high accuracy relative to a heating chamber of a wide shape. <P>SOLUTION: In a control part 60, the inside of the heating chamber 34 is divided to a plurality of blocks, and the block with a low temperature is determined by temperature detection information from an infrared sensor 59. Motors 40, 41 are controlled in order to collectively heat the determined block as a target, a portion with strong radiation directivity in at least one rotation antenna of two rotation antennas 38, 39 is set to a predetermined direction. Thereby, the microwave can be strongly radiated toward the block with low temperature, and heating can be easily and collectively performed relative to the portion with low temperature of the article to be heated. Accordingly, the whole uniform heating with high accuracy can be attained. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
