Abstract

A cooking appliance includes a housing having a cooking chamber, a door, and a guide apparatus with a locking apparatus, which can lock the coupled state between the door and the guide apparatus. The locking apparatus has a bearing support with a holder, in which in the coupled state a bearing element engages. The locking apparatus has a tubular sleeve with a carrier, which is supported rotatably on the bearing support, so that in the coupled state when the sleeve is in a first rotational position, an unlocking position can be established between the sleeve and the bearing element and in the coupled state when the sleeve is in a second rotational position, a locking position can be established between the sleeve and the bearing element.

First claim

What is claimed is:

1. A cooking appliance, comprising:
a housing;
a cooking chamber configured in the housing;
a door for closing the cooking chamber;
a guide apparatus for guiding the door as the door is moved; and
a coupling facility coupling the door to the guide apparatus, said coupling facility comprising a locking apparatus configured to lock a coupled state between the door and the guide apparatus and including a bearing support with a holder, in which in the coupled state a bearing element, which is arranged on the door, engages, said locking apparatus including a door-distal tubular sleeve supported on the bearing support for rotation into a first rotational position in which in the coupled state an unlocking position is established between the sleeve and the bearing element, and into a second rotational position in which in the coupled state a locking position is established between the sleeve and the bearing element, said sleeve including a carrier configured in one of two ways, a first way in which the carrier automatically contacts a contact element of the door when the door is moved, and causes upon further movement of the door to dynamically couple the sleeve to the door and to automatically rotate the sleeve from the unlocking position to the locking position, a second way in which the carrier automatically contacts a contact element of the guide apparatus when the door is moved, and causes upon further movement of the door to automatically rotate the sleeve from the unlocking position to the locking position when the door moves relative to a coupling element of the guide apparatus.

2. The cooking appliance of claim 1 , wherein the carrier is arranged in a movement path of the door so that when the door pivots, the carrier is automatically brought into contact with the contact element of the door, and when the door pivots further, the sleeve is dynamically coupled to the door and the sleeve is rotated automatically from the unlocking position to the locking position.

3. The cooking appliance of claim 1 , wherein the sleeve includes a circumferential wall having an outer face and running around a rotation axis of the sleeve, said carrier extending radially outward from the circumferential wall.

4. The cooking appliance of claim 3 , wherein the carrier is oriented such as to cantilever freely.

5. The cooking appliance of claim 1 , wherein the sleeve includes a circumferential wall having an outer face and running around a rotation axis of the sleeve, said carrier extending axially from the circumferential wall.

6. The cooking appliance of claim 5 , wherein the carrier is oriented such as to cantilever freely.

7. The cooking appliance of claim 1 , wherein the sleeve is supported for rotation about a rotation axis relative to the bearing element and extends parallel or coaxial to a pivot axis, about which the door is rotatable relative to the guide apparatus.

8. The cooking appliance of claim 1 , wherein the holder in the bearing support has a radial opening at a radially outer end thereof for insertion of the bearing element into the holder.

9. The cooking appliance of claim 8 , wherein the sleeve has a circumferential wall, in which an only partially circumferential cutout is configured and arranged in the locking position in a same location as the opening when viewed in an azimuthal direction about a rotation axis of the sleeve, so that the opening is uncovered in a radial direction.

10. The cooking appliance of claim 8 , wherein the sleeve has a circumferential wall, in which an only partially circumferential cutout is configured and arranged in the locking position with an offset from the opening when viewed in an azimuthal direction about a rotation axis of the sleeve, so that the opening is closed by the circumferential wall in a radial direction and the bearing element is locked in the holder to prevent the bearing element moving radially out of the opening.

11. The cooking appliance of claim 1 , wherein the bearing element is arranged in a fixed position on the door, so that to couple the door to the guide apparatus insertion of the bearing element is only possible in a first oblique position of the door as a coupling fitting position, with the coupling fitting position being different from a fully opened position of the door and different from a fully closed position of the door, said door being arranged in the coupling fitting position at a distance from the carrier in an azimuthal direction about a rotation axis of the sleeve.

12. The cooking appliance of claim 11 , wherein the contact element of the door is arranged in the coupling fitting position at a distance from the carrier in the azimuthal direction about the rotation axis of the sleeve.

13. The cooking appliance of claim 11 , wherein a contact position of the door, which contact position is different from the first oblique position and in which the carrier has just been brought into mechanical contact with the contact element, is a position that is different from the fully opened position of the door and different from the fully closed position of the door.

14. The cooking appliance of claim 13 , wherein the contact position is a second oblique position, in which the door is opened further in relation to a vertical than in the first oblique position or the door is opened less far in relation to the vertical than in the first oblique position.

15. The cooking appliance of claim 1 , further comprising a fixing apparatus configured to fix the sleeve in an azimuthal direction about a rotation axis at least in the locking position.

16. The cooking appliance of claim 1 , wherein the housing has a stowage space for receiving the door, when the door is introduced into the housing as the door opens, said guide apparatus being configured to guide the door as the door is moved into the stowage space or as the door is moved out of the stowage space.

17. The cooking appliance of claim 16 , wherein the guide apparatus has an engagement region, into which the carrier extends when viewed in a widthwise direction of the cooking appliance, said coupling element of the guide apparatus having a boundary wall configured to form a stop against which the carrier strikes as the door is inserted into the stowage space, so that when the door is pushed further into the stowage space, the sleeve is rotatable automatically into the locking position about a rotation axis of the sleeve.

18. A method for fitting a door of a cooking appliance on a guide apparatus of the cooking appliance, said method comprising:
establishing a coupling fitting position of the door in relation to the guide apparatus;
rotating a sleeve of a locking apparatus, which is configured to lock a coupled state between the door and the guide apparatus, into a first rotational position for establishing an unlocking position of the locking apparatus;
inserting a bearing element on the door into a door-distal tubular sleeve of the locking apparatus; and
moving the door out of a first oblique position, which is held by the door in the coupling fitting position, into a different position, thereby causing the sleeve to rotate automatically from the unlocking position to a locking position and establishing a locked state of the locking apparatus.
