Abstract

The present invention relates to an oven door opening and closing device comprising at least one hinge, which is 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 means for generating a predetermined closing force; kinematic means, which are 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; and at least one damping system having 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.

Claims

1. An oven door opening and closing device (10;

40;

60;

70;

80;

90) comprising at least one hinge (14), which is connectable to an oven door (12) and to an oven housing for realizing a predetermined pivoting opening and closing movement of the oven door (12) relative to the oven housing between an open and a closed position;

at least one closing force generating means (17) for generating a predetermined closing force;

kinematic means, which are coupled to the hinge (14) and to a moveable element (20;

42;

82;

96) in such a manner, that the predetermined pivoting opening and closing movement of the hinge (14) is converted into a predetermined reciprocating opening and closing movement of the move-able element (20;

42;

82); and

at least one damping system (26;

48;

62;

84;

95) having a damper (34;

52;

64;

72;

88;

951, 952) for generating a damping force which counteracts the closing movement of the movable element (20;

42;

82;

96) within a predetermined section, which corresponds to a predetermined angle section (β

) of the pivoting closing movement of the hinge (14) shortly prior to the closed position.

2. An oven door opening and closing device (10;

40;

60;

70;

80;

90) according to claim 1, characterized in that the predetermined angle (α

+β

) between the open and the closed position is about 90 degree.

3. An oven door opening and closing device (10;

40;

60;

70;

80;

90) according to claim 1, characterized in that at least one hinge housing (16) is provided, which is fixable to the oven housing.

4. An oven door opening and closing device (10;

40;

60;

70;

80;

90) according to claim 3, characterized in that the movable element (20;

42;

82;

96) is guided within the hinge housing (16).

5. An oven door opening and closing device (10;

40;

60;

70;

80;

90) according to claim 1, characterized in that the predetermined angle section (β

) of the pivoting closing movement of the hinge (16) reaches from an opening angle of about 30 degree to 0 degree, which corresponds to the closed position of the hinge (14).

6. An oven door opening and closing device (10;

40;

90) according to claim 1, characterized in that the damping system (26;

48) comprises a conversion mechanism (22;

44;

96) for transforming the linear movement of the moveable element (20;

42;

96) into a rotational movement of a rotary element (24;

46;

952), and in that the damper is a rotary damper (34;

52;

95;

951, 952) for damping said rotational movement of the rotary element (24;

46;

952).

7. An oven door opening and closing device (10;

40;

60;

70;

80;

90) according to claim 6, characterized in that the conversion mechanism (22;

44) comprises a threaded spindle (24) and a spindle nut (28).

8. An oven door opening and closing device (10;

40;

60;

70;

80;

90) according to claim 7, characterized in that the rotary damper (34) is arranged at the threaded spindle (24) or at the spindle nut (28;

951).

9. An oven door opening and closing device (10;

40;

60;

70;

80;

90) according to claim 6, characterized in that

the rotary damper (34) comprises an inner part (34a) and an outer part (34b) and in that a or the threaded spindle (24) interacts with the inner part (34a) or the outer part (34b) of the rotary damper (34) and/or in that the rotary damper (34) comprises a or the spindle nut (28) and/or a or the threaded spindle (24).

10. An oven door opening and closing device (90) according to claim 6, characterized in that the rotary damper (95) comprises a) a free run function, so that the damping function is working into one direction only, especially implemented by a damper stop element (953) and/or b) a threaded nut (951) screwed onto a spindle (952) to form a rotary damping element.

11. An oven door opening and closing device (10;

40;

60;

70;

80;

90) according to claim 1, characterized in that the damping system (26;

48;

62;

84) comprises returning means (32;

54) for returning the component, which is to be damped, in a predetermined position.
