  • Patent number: 9243362
    Abstract: The invention relates to a method for mounting a panel (1) of an appliance, especially of a domestic appliance, comprising the steps: a) Arranging of a panel element (2); b) Applying a first adhesive (3) and a second adhesive (4) onto a surface of the panel element (2); c) Pressing a transparent pane element (5) against the surface of the panel element (2) in a mounting position so that the first and the second adhesive (3, 4) have contact with the panel element (2) as well as with the pane element (5); d) Activating the adhesion of the second adhesive (4) to bond the pane element (5) with the panel element (2); e) Applying a third adhesive (6) and a fourth adhesive (7) onto a surface of the pane element (5); f) Pressing a frame element (8) against the surface of the pane element (5) in a mounting position so that the third and fourth adhesive (6, 7) have contact with the pane element (5) as well as with the frame element (8); g) Activating the adhesion of the fourth adhesive (7) to bond the frame element (8)

  • 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.

  • Patent number: 9004623
    Abstract: A door for a domestic appliance, in particular for a cooking oven. The door comprises two door columns on the left hand side and on the right hand side of the door, an outer door panel at the outer sides of the door columns, an inner door panel at the inner sides of the door columns, and a cover frame for covering the top sides of the door columns and the inner door panel. In a mounted state the cover frame is fastened on the door columns, and the inner door panel is clamped by the cover frame. In an intermediate state the cover frame is fastened at the door columns in another position as in the mounted state, so that the inner door panel is removable from the inner sides of the door columns. Further, a corresponding domestic appliance with at least one door.

  • Patent number: 8847119
    Abstract: The present invention relates to a cooking oven with at least one oven cavity, at least one air outlet conduit and at least one catalytic filter system, in particular a fat, grease and/or odor filter system. The catalytic filter system comprises a housing (10, 14) containing a catalyser element (12). The catalytic filter system is arranged within the air outlet conduit and outside of the oven cavity. The housing (10) includes a plurality of the inlet holes (20) in a wall (16) facing the oven cavity. The housing (10) includes a plurality of the outlet holes (34) in a wall (30) opposite to the oven cavity. The catalytic filter system is fixed outside of the oven cavity by fixing elements. At least one heating element (40; 50) is arranged upstream of the catalytic filter system. The heating element (40; 50) is provided for heating the catalytic filter system.
