Abstract: The inventive waffle iron has two baking sub-assemblies pivotable with respect to each other from an open position and a closed proximate position in which they define a baking chamber. At any position of the baking sub-assemblies between the closed proximate position and the closed offset position thereof, wherein they are offset from each other by a product expansion, a peripheral element of a baking sub-assembly slides along a corresponding peripheral element of the other baking sub-assembly in such a way that the variable volume baking chamber is formed.

Abstract: The inventive waffle iron comprises two baking sub-assemblies pivotable with respect to each other from an open position to a closed proximate position in which they define a baking chamber. The waffle iron also comprises at least one exhaust pipe provided with an orifice which is open above the central plane of the baking chamber when two baking sub-assemblies are in the closed proximate position thereof.
