Abstract

PURPOSE:To improve the convenience in use by a constitution wherein the interior of a heating chamber is cooled with a cooling fan when the temperature in the heating chamber gets out of the temperature range, within which a sensor is capable of normal operation, at the heating cooker provided with a humidity sensor and a temperature detecting element within the high-frequency heating chamber. CONSTITUTION:Temperature isgnal detected with the temperature detecting element 37 is inputted to a microcomputer 51. When the temperature detected with the temperature detecting element 37 lies within the range, in which the sensor 36 is capable of normal operation, relays 45 and 55 are closed, resulting in putting a magnetron 33 and in operation and in driving a fan motor 38 in order to cool the magnetron 33 to ventilate the interior of the heating chamber 31. When the temperature detecting element 37 detects that the temperature in the heating chamber ascends so high as to get out of the range, within which the sensor 36 is capable of normal operation, the microcomputer 51 opens the relay 45 to stop heating and to cool the heating chamber by means of the fan 38. In such a manner as mentioned above, because the temperature in the heating chamber can be automatically cooled, the convenience in use of the cooker can be improved.
