Abstract

The invention concerns a working chamber for an electrical household food processor, comprising a vessel (1) and a lid (3), the vessel and the lid comprising hinge means (10). The invention is characterised in that the hinge means (10) comprise two matching nesting surfaces (7, 8), one (7) integral with the lid (3) and the other (8) integral with the vessel (1), having at least along one pivot axis a series of at least partly circular sections perpendicular to said pivot axis.

Claims

1. A working enclosure for an electrical household food preparation appliance comprising a vessel (1;

1′

;

1″

) and a lid (3;

3′

;

3″

), the vessel and the lid having articulation means (10;

10′

;

10″

), characterized in that the lid (3;

3′

;

3″

) is removable from the vessel (1;

1′

;

1″

), the articulation means (10;

10′

;

10″

) have two complementary nesting surfaces (7,8;

7′

, 8′

;

7″

, 8″

), one (7;

7′

;

7″

) integral with the lid (3;

3′

;

3″

) and the other (8;

8′

;

8″

) integral with the vessel (1;

1′

;

1″

), presenting along at least one pivot axis, at least one partially circular section perpendicular to said pivot axis.

2. Enclosure according to claim 1, characterized in that the complementary nesting surfaces are respectively male (7;

7′

;

7″

) and female (8;

8′

;

8″

).

3. Enclosure according to claim 2, characterized in that the female nesting surface (8;

8′

;

8″

) is formed by a concave surface extending at most over an angle of substantially 180°

.

4. Enclosure according to claim 3, characterized in that the concave nesting surface (8;

8′

;

8″

) is integral with the vessel (1;

1′

;

1″

), respectively with the lid, at least a portion of this surface being situated above, respectively below, a plane parallel to the upper edge of the vessel and passing through the center of curvature of said concave surface.

5. Enclosure according to claim 4, characterized in that the complementary nesting surfaces (7, 8) are hemispherical surfaces.

6. Enclosure according to claim 2, characterized in that the male nesting surface (7;

7″

) has a free end provided to be engaged along the pivot axis against the female nesting surface (8;

8″

).

7. Enclosure according to claim 2, characterized in that the male (7;

7′

;

7″

) or female nesting surface integral with the lid (3;

3′

;

3″

) is situated at the end of an arm (6;

6′

;

6″

) that projects toward the outside.

8. Enclosure according to claim 2, characterized in that the male or female (8;

8′

;

8″

) nesting surface integral with the vessel (1;

1′

;

1″

) is arranged on a handle (9;

9′

;

9″

) of the vessel.

9. Enclosure according to claim 1, characterized in that the lid (3) has an inner (3b), respectively outer (3c) annular nesting surface extending perpendicular to the plane formed by the edge of the lid (3) adjacent to the edge (1a) of the vessel (1) and dimensioned to be nested at the inside, respectively the outside, of the opening of the vessel (1), the dimension of this surface (3b;

3c) perpendicular to said plane formed by the edge of the lid (3) being smaller in its part opposed to the articulation means (10), respectively in its part closest to the articulation means (10).

10. Enclosure according to claim 9, characterized in that the lower edge of the inner annular nesting surface (3b) has at least one recess (3d) while the inner wall of the vessel (1) has at least one positioning projection (1b) disposed to come to engage with said recess (3d) in position for closing the vessel (1).

11. Electrical household appliance for food preparation having a housing (11) forming a base (12) for receiving a vessel (1) closed by a lid (3), the vessel and the lid having articulation means (10), locking means (5) to maintain the lid in its closing position on the vessel being provided on the housing in order to cooperate with a locking surface (3a) of the lid, characterized in that the vessel (1) and lid (3) form a working enclosure in accordance with claim 1.

12. Appliance according to claim 11, characterized in that the articulation means (10) have a concave nesting surface (8) integral with the vessel (1), respectively with the lid, at least a portion of this surface being located above, respectively below, a plane passing through the center of curvature (0) of said concave surface and through the bearing point of the locking means (5) on the locking surface (3a) of the lid when said locking the articulated lid (3) on the vessel (1) in the closed position.

13. Appliance according to claim 12, characterized in that the locking means (5) come to bear on the lid (3) in a region diametrically opposed to the articulation means (10).

14. Appliance according to claim 12, characterized in that the locking means (5) come to bear on the top of the lid (3).
