Electrically operated food processor with a cooking vessel, and vessel with a lid
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.
1. A cooking vessel comprising:
a vessel body;
a lid; and
a locking mechanism; wherein
the vessel has a base, a wall, and a radially projecting rim, wherein the vessel wall merges into the radially projecting rim;
the lid has a lid edge which overlies the radially projecting rim;
wherein the locking mechanism comprises a locking part which removably secures the lid to the radially projecting rim;
the locking part ( 17 ) comprises an elongated member having a wave-like design comprising a cavity ( 20 ) that extends over the axial length of the locking part; an upper edge of the cavity further having an arc like engaging portion ( 21 ) and a spherically shaped projecting contact area ( 23 ) within the center of the cavity;
wherein the locking part rotates to secure the lid edge to the vessel projecting rim in a positive fit manner.
2. The cooking vessel according to claim 1 , wherein the locking part rotates about a geometric axis (y), the geometric axis (y) runs in its extent parallel to a plane (E) that is determined by the 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.
3. The cooking vessel according to claim 1 , wherein a geometric axis (y) of the locking part is situated outside the vessel wall ( 12 ).
4. The cooking vessel according to claim 1 , wherein a geometric axis (y) of the locking part passes through the vessel wall ( 12 ).
5. The cooking vessel according to claim 1 , wherein a geometric axis (y) of the locking part extends beneath the vessel rim ( 13 ).
6. The cooking vessel according to claim 1 , wherein the locking part ( 17 ) is rotatably drivable from an end portion from a release position into a locking position, and vice versa.
7. The cooking vessel according to claim 1 , wherein in a locked state at least two over-engaging portions ( 21 ) at a distance from one another in a peripheral direction of the lid edge ( 16 ) are provided on the locking part ( 17 ).
8. The cooking vessel according to claim 7 , wherein in the locked state outermost locking areas of a locking part ( 17 ) are separated from one another by a distance that is 1/10 to ½ of the lid diameter (d).
9. The cooking vessel according to claim 1 , 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° .
10. The cooking vessel according to claim 1 , wherein the locking part ( 17 ) would rotate between 30° to 90° between an open position and a closed position where it is secured to the vessel rim.
11. The cooking vessel according to claim 1 , wherein a stationary over-engaging element ( 24 ) is formed opposite from the locking part ( 17 ).
12. The cooking vessel according to claim 1 , wherein two locking parts ( 17 ) are oppositely situated with respect to a center axis (x) of the vessel ( 6 ).
13. The cooking vessel according to claim 1 , wherein two oppositely situated locking parts ( 17 ) are provided, and rotational axes (y) of the locking parts ( 17 ) are enclosing an acute angle in a top view.
14. The cooking vessel according to claim 13 , wherein a stationary over-engaging element ( 24 ) is formed diametrically opposite from a point of intersection of the two rotational axes (y).
15. The cooking vessel according to claim 1 , wherein the contact area ( 23 ) is provided centrally, with respect to the longitudinal extent of the locking part ( 17 ), between the outermost locking areas.
16. The cooking vessel according to claim 1 , 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 ).
17. An electrically operated kitchen appliance having a vessel ( 6 ) according to claim 1 as a cooking vessel.
