Abstract

The invention concerns a food processor (1) with a mixing vessel (6) and a drive mechanism (8) for an agitator (10) in the mixing vessel (6), the lower region of which can be heated. As an improvement on a food processor (1) of this type, it is proposed that a weighing device (16) should be provided and that the weighing device (16) should determine the weight of a mixing pot support (7) including a heating unit (40).

Claims

1. A food processor comprising

a mixing vessel and a drive mechanism for an agitator in the mixing vessel, the mixing vessel being heatable in its lower region, and

a weighing device, and wherein the weighing device senses the weight of a mixing bowl support, including a heater unit.

2. A food processor according to claim 1, wherein the weighing device support components to be weighed by means of a three-point bearing.

3. A food processor according to claim 1, wherein bearing points are each associated with end regions of weighing device.

4. A food processor according to claim 3, wherein the bearing points are each fitted with a damping member.

5. A food processor according to claim 1, wherein the weighing device records the weight of the drive mechanism.

6. A food processor according to claim 1, further comprising a weighing beam, and the weighing beam is aligned along an axial elongated extent between the agitator and the drive mechanism.

7. A food processor according to claim 6, wherein the mixing vessel is oval in shape in plan view and the weighing beam is aligned along the greater axis in plan view.

8. A food processor according to claim 6, wherein the weighing beam is accommodated in a weighing housing having a horizontal division.

9. A food processor according to claim 8, wherein an upper portion of the weighing housing is held captive on a lower portion by means of a stop safety effective in both directions.

10. A food processor according to claim 8, wherein the weighing housing is T-shaped in plan view.

11. A food processor according to claim 8, wherein two T-beams of the weighing housing extend at an acute angle to one another.

12. A food processor according to claim 10, wherein an arm of the T-shaped weighing housing is formed wedge-shaped.

13. A food processor according to claim 12, wherein a wedge shape of the arm is defined by a projection of two arms of a lower portion and of an upper portion of the weighing housing, the two arms being angled and handle-shaped.

14. A food processor according to claim 13, wherein the upper portion and the lower portion are formed, at least with regard to their outer contours, identical in shape.

15. A food processor according to claim 1, further comprising a chassis and a weighing housing, and wherein the mixing bowl support and the drive mechanism are fully located on the chassis, and the chassis acts upon the weighing housing.

16. A food processor according to claim 15, wherein the chassis acts upon the weighing housing by means of three bearing points located in end regions of the weighing housing which is T-shaped in plan view.

17. A food processor according to claim 16, further comprising rubber buffers between said bearing points and said chassis.
