Description

Further advantages are evident from the following description of the figures. The figures show an exemplary embodiment of the invention. The figures, the description and the claims contain numerous combined characteristics which the person skilled in the art will also consider individually and combine to provide further logical combinations.

FIG. 1 shows a cooking device with an equipment door, a bolting device element and an actuator in a partial section,

FIG. 2 shows the cooking device in FIG. 1, with the equipment door open, in an obliquely downward view,

FIG. 3 shows a detailed view of a locking hook of the bolting device element in FIGS. 1 and 2,

FIG. 4 shows a detailed view of the equipment door in FIGS. 1 and 2, with a corresponding bolting device element, and

FIG. 5 shows a sectional representation of the corresponding bolting device element in FIG. 5.

FIG. 1 shows a cooking device designed as a domestic oven with a pyrolysis function, with an equipment door 10, an actuator unit 12 and with a bolting device element 14 for locking the equipment door 10. Bolting device element 14 serves to lock the equipment door 10, particularly during the performance of the pyrolysis function, actuator unit 12 being provided to bring bolting device element 14 into engagement with a corresponding bolting device element 15 or with a locking shell of equipment door 10 for locking equipment door 10 when equipment door 10 is closed.

Bolting device element 14 is rotatable about a rotating axis 16 by means of actuator unit 12, which axis, when equipment door 10 is closed, runs perpendicularly to a door plane and, when the cooking device is erected, runs horizontally above a cooking space.

Bolting device element 14 comprises a rod 18 and a locking hook 20 running perpendicularly to rotating axis 16. Rod 18 bridges a distance of at least 20 cm between actuator unit 12 and locking hook 20. Locking hook 20 projects at right angles from rod 18. Rod 18 is mounted rotatably and axially fixedly in a guide bearing 22 on a cooking device body of the cooking device. Guide bearing 22 screens all the forces acting in the region of locking hook 20 on bolting device element 14 from actuator unit 12, so that it cannot be damaged, even by pulling on equipment door 10.

Corresponding bolting device element 15 of equipment door 10 is designed as a shell-shaped recess or as a locking shell in a lateral edge surface 24 of equipment door 10, which has the shape of a quadrant in a view perpendicular to equipment door 10 (FIG. 5).

Equipment door 10 is pivotable by means of hinges, not shown explicitly here, about a pivoting axis 26 running along a first, lower edge. Corresponding bolting device element 15 is arranged on an upper lateral edge of equipment door 10 opposing the first edge (FIG. 4).

A radial limiting surface 30 of corresponding bolting device element 15, aligned perpendicularly to pivoting axis 26 of pivoting axis 26 of equipment door 10, forms a stop surface 28 for limiting a rotary movement of bolting device element 14.

A further limiting surface 30 of corresponding bolting device element 15 forms a section of a surface area that is axially symmetrical to rotating axis 16 of bolting device element 14 when equipment door 10 is closed, in particular a section of a cylindrical surface area.

Rod 18, by means of which bolting device element 14 or locking hook 20 is connected to actuator unit 12, forms a torsional spring element 32. If, for example, equipment door 10 is not fully closed, or if corresponding bolting device element 15 of equipment door 10 is contaminated, locking hook 20 cannot reach stop surface 28. Because of the torsion of rod 18 or torsional spring element 32, the loading of actuator unit 12 nevertheless remains within a permissible range and damage to actuator unit 12 by overheating or similar can be avoided.

If bolting device element 14, with the locking hook, rotates beyond the locking position defined by stop surface 28 when the locking is activated, corresponding bolting device element 15 is not present in the locking position because, for example, equipment door 10 is not fully closed.

The cooking device comprises a sensor element 34 for detecting a position of bolting device element 14, by means of which a central control unit is able to detect whether bolting device element 14 is in the locking position. The latter is a necessary condition for locking equipment door 10.

Moreover, the cooking unit has a further sensor element 36, designed as a reed switch, for detecting a position of equipment door 10. This also enables the control unit to detect an adequate condition for locking equipment door 10. Only when bolting device element 14 is in the locking position and equipment door 10 is fully closed, a safe positive connection exists and equipment door 10 can no longer be opened. The control unit does not initiate a pyrolysis process until all the conditions are met.

Bolting device element 14 and further sensor element 36, for detecting a position of equipment door 10, extend through similar types of recesses 38, 40 in a front plate of a muffle 42 of the cooking device. Both units are therefore interchangeable in terms of their installation position.

Actuator unit 12 itself is arranged above muffle 42 in a rear half of the cooking unit relative to a cooking space opening that can be sealed from equipment door 10. The installation space in the front half of the cooking device therefore remains free for other modules which can be operated directly by means of an operating diaphragm 44 of the cooking device and should therefore be arranged in the immediate vicinity of the latter to form a compact module.
