Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a range hood that eliminates a temperature detection error due to such as differences in types of pans in use, accurately recognizes dirt of a sensor part, and maintains a state where a sensor detection temperature can be always accurately detected.SOLUTION: The range food includes: a thermoelectromotive-force type temperature sensor 5 which measures a temperature near a top plate 4 of a heating cooker; a detection window 7 which prevents the thermoelectromotive-force type temperature sensor 5 from getting dirty, the detection window being included between the thermoelectromotive-force type temperature sensor 5 and the top plate 4; a first temperature detector 6 which measures an ambient temperature of the thermoelectromotive-force type temperature sensor 5; a second temperature detector 8 which detects an ambient temperature, the second temperature detector being attached to a part which is not affected by a temperature of the top plate 4; and a controller. While a temperature detected by the first temperature detector 6 is higher than a temperature detected by the second temperature detector 8, when a temperature of the thermoelectromotive-force type temperature sensor 5 is equal to or lower than a predetermined threshold temperature, the controller recognizes that dirt has adhered on the detection window 7. |
