Abstract

The invention relates, in the first instance, to an electrically operated food processor (1) with a cooking vessel (6) and a lid (10) for the cooking vessel (6), wherein it is possible to lock the lid (10) in the closed position in relation to the cooking vessel (6), wherein, furthermore, the cooking vessel (6) has a base and a wall (12) extending upwards from the base, wherein the cooking-vessel wall (12) merges into a radially projecting cooking-vessel periphery (13), wherein, furthermore, the lid (10) has a periphery (16) which, in the closed position, coincides with the cooking-vessel periphery (13). The invention also relates to a vessel (6) with a lid (10). In order further to improve a food processor and/or a vessel of the type in question, in particular in respect of the lid-locking means, it is proposed that the locking means is formed from a locking part (17) which is intended for engaging over the lid (10) and, by rotation about an axis (y), can be displaced from a release position into the locking position and vice versa, wherein the locking part (17) is of elongate design in the direction in which the axis (y) extends.

Claims

1-14. -14. (canceled)

15. Vessel (6) having a lid (10), in the closed position the lid (10) being lockable against the vessel (6), the vessel (6) also having a vessel base and a vessel wall (12) extending upwardly from the base, the vessel wall (12) merging into a radially outwardly projecting vessel rim (13), the lid (10) also having a lid edge (16) which in the closed position overlies the vessel rim (13), the locking being formed from a locking part (17) which is for engaging over the lid (10), the locking part being displaceable from a release position into the locking position and vice versa by rotation about an axis (y), the locking part (17) being elongated in the direction of extent of the axis (y), wherein the locking part, which is formed with an overall wave-like design, is provided with a cavity (20) that extends over the axial length, wherein, with respect to a vertical cross-section, a circular arc-like over-engaging portion (21) is provided and the cavity portion (22) covered by the over-engaging portion (21) is adapted, with regard to its radial extent and also with regard to its extent in the peripheral direction, for accommodating in a positive-fit manner the vessel rim (13) as well as the lid edge (16) of the lid (10) mounted on the vessel (6).

16. Vessel according to claim 15, wherein the geometric axis (y) runs in its extent parallel to a plane (E) that is determined by a lid edge (16) or at an acute angle of 0.5°

to 30°

with respect to said plane, the plane being transverse with respect to a vertically aligned vessel axis.

17. Vessel according to claim 15, wherein the geometric axis (y) is situated outside the vessel wall (12).

18. Vessel according to claim 15, wherein the geometric axis (y) passes through the vessel wall (12).

19. Vessel according to claim 15, wherein the geometric axis (y) extends beneath the vessel rim (13).

20. Vessel according to claim 15, wherein the locking part (17) is rotatably drivable from one or both end portions from the release position into the locking position, and vice versa.

21. Vessel according to claim 15, wherein in the locked state at least two over-engaging portions (21) at a distance from one another in the peripheral direction of the lid edge (16) are provided on the locking part (17).

22. Vessel according to claim 21, wherein in the locked state the outermost locking areas of the locking part (17) are separated from one another by a distance that is 1/10 to ½

of the lid diameter (d).

23. Vessel according to claim 15, wherein the locking part (17) engages over the lid edge (16) in a circular arc-like manner in cross-section over a range of 30°

to 90° and

/or approaches this range.

24. Vessel according to claim 15, wherein the locking part (17) moves towards the lid edge over a circular arc-like range of 30°

to 90°

.

25. Vessel according to claim 15, wherein a stationary over-engaging element (24) is formed opposite from the locking part (17).

26. Vessel according to claim 15, wherein two locking parts (17) are oppositely situated with respect to a center axis (x) of the vessel (6).

27. Vessel according to claim 15, wherein two oppositely situated locking parts (17) are provided, the axes (y) enclosing an acute angle in a top view.

28. Vessel according to claim 27, wherein a stationary over-engaging element (24) is formed diametrically opposite from the point of intersection of the two rotational axes (y).

29. Vessel according to claim 15, wherein the locking part (17) has a contact area (23) for the vessel rim (13).

30. Vessel according to claim 29, wherein the contact area (23) has a spherical head shape.

31. Vessel according to claim 29, wherein the contact area (23) is provided centrally, with respect to the longitudinal extent of the locking part (17), between the outermost locking areas.

32. Vessel according to claim 29, wherein the locking part (17) has two contact areas (23) for the vessel rim (13) which are offset over the periphery of the vessel rim (13).

33. Electrically operated kitchen appliance having a vessel (6) according to claim 15 as a cooking vessel.
