Claims
- 1. A wall-mounted cooking appliance, comprising:
a housing formed with a muffle and a bottom muffle opening; a lowerable bottom door for selectively closing said bottom muffle opening; a drive mechanism having at least one tensile element connected to said bottom door, said tensile element being stressed against a weight of said bottom door with a tensile force; and tensile stress means assigned to said tensile element for maintaining a minimum amount of the tensile force in said tensile element if a stress on said tensile element is otherwise relieved.
- 2. The cooking appliance according to claim 1, wherein said tensile stress means is a spring.
- 3. The cooking appliance according to claim 1, wherein said tensile stress means is disposed to pre-tense said drive mechanism.
- 4. The cooking appliance according to claim 1, wherein said drive mechanism has a driven shaft for power transfer and at least one winding drum mounted on said driven shaft for winding and unwinding said tensile element, and said driven shaft exerts a tensile force on said tensile element via said winding drum.
- 5. The cooking appliance according to claim 4, wherein said tensile stress means is configured to exert a stress torque opposing a weight on said winding drum.
- 6. The cooking appliance according to claim 5, wherein said winding drum is formed with a take-up space, and said tensile stress means is disposed in said take-up space.
- 7. The cooking appliance according to claim 5, wherein said winding drum is rotatably mounted on said driven shaft through an angle of rotation, and said winding drum is formed with a rotational stop to be pivoted through the angle of rotation between a first and a second counterstop carried on said driven shaft, and wherein said rotational stop is pressed onto said first counterstop by a weight of said bottom door.
- 8. The cooking appliance according to claim 4, wherein said winding drum is one of two winding drums commonly mounted on said driven shaft, and each one of said winding drums is assigned a respective said tensile element.
- 9. The cooking appliance according to claim 8, wherein said winding drums are in contact with one another and rotatable relative to one another.
- 10. The cooking appliance according to claim 9, wherein said winding drums delimit a take-up space thereinbetween, said take-up space accommodating said tensile stress means therein.
- 11. The cooking appliance according to claim 10, wherein said rotational stops of said winding drums and said counterstops of said driven shaft are disposed in said take-up space.
- 12. The cooking appliance according to claim 9, wherein said first and second counterstop of said driven shaft are assigned to each of said two winding drums.
