Abstract
There is disclosed a novel flat heating surface type gas stove which is capable of heating a heating substance across a heat resistant glass at a practically applicable heating efficiency, thereby overcoming any inconvenience resulting from the exposure of flame and facilitating the cleaning of the gas stove. This gas stove comprises a heat resistant glass top plate which is disposed over a burner , wherein a gas-permeable porous body is disposed below said top plate , and a space between said top plate and a surface of said gas-permeable porous body is assigned to a combustion space S. Combustion gas generated is designed to be discharged through said gas-permeable porous body . As high-temperature combustion gas passes through said gas-permeable porous body , radiant heat B is generated from the surface of said gas-permeable porous body . Since the heating substance is heated by both of heat conduction and radiation, high heating efficiency can be achieved.
