Abstract

A household mixer appliance having a mixing container with an inner surface and an open top, a drive arrangement and a hook. The hook has a sole attachment portion which, when attached to the drive arrangement, abuts a first inner surface portion of the mixing container inner surface. The sole attachment portion is attachable to the drive arrangement via a through hole in the first inner surface portion such that the hook is rotatable around a substantially horizontal axis of rotation within the mixing container when the hook is attached to the drive arrangement.

First claim

The invention claimed is:

1. A household mixer appliance comprising:
a mixing container with an inner surface and an open top;
a drive arrangement; and
a hook;
wherein the hook comprises a proximal end, a distal end and a curved portion extending between the proximal end and the distal end, the proximal end having a sole attachment portion which when attached to the drive arrangement abuts a first inner surface portion of the mixing container inner surface, and is attachable to the drive arrangement via a through hole in the first inner surface portion such that the hook is rotatable around a horizontal axis of rotation within the mixing container when the hook is attached to the drive arrangement, the hook further having a distal-most point located at its most distant point from the proximal end, the distal-most point of the hook being offset from the axis of rotation to define a circular path as the hook rotates about the axis of rotation; and
wherein the inner surface of the mixing container comprises a second inner surface portion comprising at least 40% of the mixing container inner surface having the shape of an oblate spheroid,
wherein the inner surface of the mixing container comprises a third inner surface portion arranged diametrically from the first inner surface portion along the axis of rotation, the third inner surface portion comprising a flat surface extending radially inward from the second inner surface portion adjacent the circular path defined by the distal-most point of the hook towards the axis of rotation of the hook, and
wherein the distal end of the hook is spaced from the flat surface by a separation distance, such that the curved portion of the hook can knead foodstuffs against the flat surface.

2. The mixer appliance according to claim 1 , wherein the drive arrangement is arranged entirely below a highest portion of the mixing container when positioned with the open top facing upwards.

3. The mixer appliance according to claim 1 , wherein the third inner surface portion comprises a protuberance located between the flat surface and the axis of rotation of the hook, and extending towards the first inner surface portion.

4. The mixer appliance according to claim 1 , wherein all parts of the hook are arranged with a separation distance to the third inner surface portion.

5. The mixer appliance according to claim 1 , wherein the hook, when in a lowest position, extends in parallel with the inner surface of the mixing container along at least 50% of a length of the hook.

6. The mixer appliance according to claim 1 , wherein the hook, when in a lowest position, extends in parallel with the inner surface of the mixing container along at least 70% of a length of the hook.

7. The mixer appliance according to claim 3 , wherein all parts of the hook are arranged with a separation distance to the third inner surface portion.

8. The mixer appliance according to claim 1 , wherein at least 50% of the mixing container inner surface has the shape of an oblate spheroid.

9. The mixer appliance according to claim 1 , wherein at least 60% of the mixing container inner surface has the shape of an oblate spheroid.

10. The mixer appliance according to claim 1 , where the curved portion of the hook positions the distal end of the hook towards the first inner surface portion.
