  • Publication number: 20210348768
    Abstract: The present invention relates to a sealing system for an oven cavity (10) of an oven, in particular of a cooking oven. The sealing system includes an outer steam-tight gasket (20) attachable or attached at a front frame (26), which encloses a cavity frame (12) of the oven cavity, which in turn encloses a front opening of said oven cavity (10). The sealing system includes an inner heat resistant gasket (18) attachable or attached at the cavity frame (12) and/or at the front frame (26), so that the inner heat resistant gasket (18) is aligned at least partially at the cavity frame (12) and at an inner panel (16) of an oven door (14) for closing the oven cavity (10) in a closed state of said oven door (14). The sealing system includes a gap sealing (19) arrangeable or arranged within a gap between the cavity frame (12) and the front frame (26), so that the gap sealing (19) encloses completely or partially the cavity frame (12).

  • Patent number: 9074400
    Abstract: An oven door opening and closing device includes at least one hinge connectable to an oven door and to an oven housing for realizing a predetermined pivoting opening and closing movement of the oven door relative to the oven housing between an open and a closed position. At least one closing force generating device generates a predetermined closing force, and a kinematic device is coupled to the hinge and to a moveable element in such a manner that the predetermined pivoting opening and closing movement of the hinge is converted into a predetermined reciprocating opening and closing movement of the moveable element. At least one damping system has a damper for generating a damping force which counteracts the closing movement of the movable element within a predetermined section, which corresponds to a predetermined angle section of the pivoting closing movement of the hinge shortly prior to the closed position.
