PROBLEM TO BE SOLVED: To provide a gas cooking device with a pot bottom temperature sensor having superior heat resistance and high detection accuracy by providing an optimum heat shielding composition of the pot bottom temperature sensor while suppressing a temperature rise of an outer circumferential face of a heat shielding tube protecting the pot bottom temperature sensor. SOLUTION: The heat shielding tube 11 is provided on a periphery of the pot bottom temperature sensor 14 for protection from combustion heat of a burner 1. In the heat shielding tube 11, multiple forced draft passages 12a and 12b are formed to turn back air supplied from a blower 10 at an upper part and guide it downward. A natural draft passage 12c carrying air by a draft effect is formed between the heat shielding tube 11 and the pot bottom temperature sensor 14. The combustion heat from the burner 1 is shielded by multiple heat shielding layers formed by the forced draft passages 12a and 12b and the natural draft passage 12c, and the heat shielding tube 11 is cooled by sending air blown out from a heat shielding tube 11 lower end along the heat shielding tube 11 outer circumferential face. A control part 10 is provided for controlling a rotational frequency of the blower 10 in response to a detected temperature of the pot bottom temperature sensor 14. COPYRIGHT: (C)2006,JPO&NCIPI
