摘要

An oven comprises a housing or structure presenting a plurality of inner walls and outer walls, the inner walls defining an oven cavity in which means are provided for cooking foods, the means comprising a grill for browning the foods, the oven also comprising a door for closing the cavity. At least one aperture is present in at least one of the walls of the oven cavity, or in the door, for selective connection to the environment external to the oven, such as to interceptably introduce fresh ambient air into the cavity, controllable interceptor means being provided at the aperture to enable this selectivity in introducing the ambient air into the cavity.
