  • Patent number: 6073624
    Abstract: A swing-out supporting arrangement (7) primarily intended for a wall-mounted oven (1) of domestic type comprises a bottom plate (6) supported by link arms (9, 10), said bottom plate (6) and an insert (8), possibly associated with said bottom plate, being retractable from the oven (1) by a swing-out movement without the use of any front door. The bottom plate (6) with the insert (8) can be moved between a first position inside the oven and a second swing-out position below and in front of the over front wall (2). Preferably, the swing-out movement is performed by means of an electric motor which is rotatable between two end positions. The principle of invention can also be used for a ceiling plate (4) supported by link arms, said plate being swingingly displaced in a corresponding lifting movement from an oven positioned at a low level.

  • Patent number: 5964211
    Abstract: A method and device for cleaning the oven cavity of a pyrolytic self-cleaning oven without using a broil element or burner. The method includes using a bake burner to maintain the temperature of the oven cavity during the first stage of the self-cleaning process at a temperature sufficiently low such that cooking residues are baked onto the oven walls and bottom without producing excessive levels of smoke. During the second stage of the self-cleaning process, the temperature inside the oven cavity is raised to clean away the baked-on residues while still maintaining acceptable levels of smoke.

  • Patent number: 5497760
    Abstract: An efficient convection oven is described. The oven utilizes a single inlet centrifugal induced back draft fan disposed in a sidewall thereof between vertical burners and combustion chambers to constantly mix products of combustion from the combustion chambers with air from within the oven cavity and recirculate the same. The fan design of the instant invention permits air changes within the oven cavity in the range of 85 to 100 per minute and the vertical burner fan combustion chamber combination permits a dramatic increase in the rack space within the oven cavity for a given oven exterior envelope.

  • Patent number: 4865010
    Abstract: An exhaust duct cooling system is provided for a built-in gas oven wherein cool air is drawn into the oven enclosure and through an oven controls area to cool that area, and then the cool air is directed into a cool air duct which is positioned between the oven cooking cavity and an oven exhaust duct to thermally isolate the controls area while cooling the oven exhaust. The cool air duct has a first, lower outlet below the oven controls, and a second, upper outlet adjacent to an outlet of the oven exhaust duct where cool air and oven exhaust are mixed in a chamber prior to exiting the oven cabinet. Thus, the oven exhaust is tempered prior to being exhausted from the front of the oven.

  • Patent number: 4848310
    Abstract: A heating device for mounting in a window opening, particularly useful for vehicles, camper shells, and other enclosures, which includes a mounting plate; air intake and exhaust tubes, a burner contained within a sealed housing, an external fuel source, and a connecting line between the fuel source and the burner. The lower portion of the mounting plate rests upon the window sill and an upper portion engages the outer surface of the window framework to make the device useable for both vertically and horizontally movable windows. The sealed housing, which includes a cooking surface, precludes noxious fumes or explosive fumes from escaping into the confines of the area being heated. The external fuel source, preferably a portable propane tank, rests on the ground outside the enclosure, as an additional safety factor. A heat deflector, pivotal over the top surface of the burner housing, disperses the heated air to prevent overheating of the ceiling and also serves as a safety guard.

  • Patent number: 4643167
    Abstract: The invention is an oven ventilation system which uses sheets of moving air to remove heat and also to insulate the oven from the remainder of the room or vehicle in which the oven is located. More particularly, the ventilation system takes air from outside the room or vehicle and forms rapidly moving sheets of air which pass over the external surfaces of the oven. After passing over one or more of the external surfaces of the oven, the sheets of air are exhausted to the outside. Preferably, the ventilation system also comprises wall means for forming a chamber to separate the oven and ventilation system from the remainder of the room or vehicle.

  • Patent number: 4114589
    Abstract: A venting system for a food processing oven includes a duct assembly comprising a housing defining an inlet into which heated air from the oven enters and first and second outlets through which the heated air is expelled to the interior or exterior, respectively, of the household in which the oven is installed. A serpentine channel formed by a series of parallel plates mounted in the housing between the inlet and outlets is provided to carry the heated air over a relatively long path to cool, permitting water vapor therein to condense on the plates before the air is expelled. A damper plate is mounted in the housing for pivotal movement in the path between the inlet and second outlet.
