PURPOSE:To enable to cook automatically irrespective of a position and the size of groceries by assuming the size and the position of groceries, by a method wherein more than one infrared detectors whose angles of incidence are different from each other are provided and respective outputs are compared with each other. CONSTITUTION:A non-contact thermometer consisting of at least two or more infrared detectors whose angles of incidence of infrared rays are different from each other and a shutter controlling the infrared rays inciding into the detectors is provided. The infrared detector shown by a range 8 of incidence of the infrared rays and that shown by a range 9 of the same are made into a first and second detectors respectively and as for shutters 10, 11, they are made into such a constitution through which the infrared rays can be made to incide into the two infrared detectors independently respectively. With this construction, the sizes of groceries and a position where the groceries are placed can be assumed by actuating the first and second detectros reciprocally and comparing them with respective output signals. Then far high level automatic cooking can be performed. |
