<p>A gas stove in which heat emitted from a side face of a combustion chamber of the stove is suppressed from being transmitted to the inside of the stove. A gas stove (1) comprises a burner (2), a porous body (3), an air-supply and -exhaust fan (6), an external periphery wall (9), an air exhaust passage (26) connecting the porous body (3) and an air exhaust opening (5), and an air supply passage (20). There is formed heat insulation space (12) sealed by the external peripheral wall (9) and a side face (11) of a combustion chamber (10) with the exception of a supply opening (13) and an exhaust opening (14) that are for air. The air supply passage (20) and the supply opening (13) are connected by an air supply branch tube (15). When the burner (2) burns, cooling air is supplied to the heat insulation space (12) through the air supply branch tube (15). The cooling air suppresses heat, emitted from the side surface (11) of the combustion chamber (10), from being transmitted to the inside of the gas stove (1), and air exhausted from the exhaust opening (14) cools exterior portions of the combustion chamber (10) of a glass top (4).</p> |
