PURPOSE:To make it possible to detect the temperature with respect to food to be cooked placed on a turntable at a position deviated from its center by providing holes for measuring the temperatures of the surfaces of a plurality of food being cooked at the ceiling portion of a heating chamber, further providing an infrared ray detector between the ceiling part and an outer shell so as to make it possible to move an infrared detecting part to any of positions of holes. CONSTITUTION:An infrared ray detector 11-b having an infrared ray sensor 11-a at the outside of the ceiling part 3-a of a heating chamber 3 is provided. The infrared ray detector 11-b rotates and moves on a horizontal plane horizontal to the ceiling portion 3-a by a motor 12, and provisions are monitored through three holes, for example. A microcomputer 18 gradually delivers scanning pulses to output terminals S0-S4 to discriminate which key button has been depressed, and operates the motor 12. As a result, the infrared ray detector can correctly detect the surface temperature of the food under cooking even when the provision is placed on the peripheral edge of the turntable by moving the sensor to a position optimum for detecting the food under cooking. |
