Abstract

An electrical food preparation appliance includes a working container enclosing a tool rotated by a motor, a device for heating the contents of the working container and a removable lid that covers the working container, the lid having an opening for inserting ingredients into the working container, at least one steam exhaust orifice, and a removable measuring cap accommodated into said opening for inserting ingredients. The measuring cap can occupy at least two stable positions in the opening of the lid and in that the motion of the measuring cap from one stable position to the other makes it possible to vary the passage cross-section of the steam exhaust orifice.

First claim

The invention claimed is:

1. A household food preparation appliance comprising a working container enclosing a tool which is rotatably driven by a motor, a device to heat contents of the working container and a removable cover that closes the working container; the removable cover contains an opening to add ingredients to the working container, at least one steam release orifice, and a removable measuring cap that is housed in said opening to add ingredients, wherein the measuring cap may occupy at least two stable positions in said opening of the cover without adjusting the placement of the cover on the working container and that moving the measuring cap from one stable position to another varies the passage cross-section of the steam release orifice,
wherein the measuring cap comprises a body having a cylindrical lower section, a flared upper section extending upwards from the cylindrical lower section, and a peripheral skirt held by the flared upper section at an end opposite the cylindrical lower section, and wherein the peripheral skirt extends downward from the end of the flared upper section.

2. A household food preparation appliance in accordance with claim 1 , wherein the measuring cap may occupy multiple successive stable positions in the opening and that moving the measuring cap from one stable position to another progressively varies the passage cross-section of the steam release orifice.

3. A household food preparation appliance in accordance with claim 1 , wherein the measuring cap rotates in the opening and that rotating the measuring cap varies the passage cross-section of the steam release orifice.

4. A household food preparation appliance in accordance with claim 1 , wherein around said opening, the cover contains a projecting funnel which forms a housing for the measuring cap and that said steam release orifice is located on an external wall of the funnel.

5. A household food preparation appliance in accordance with claim 4 , wherein the peripheral skirt of the measuring cap is located in the opening so that a portion of the peripheral skirt at least partially covers the steam release orifice on the external wall of the funnel.

6. A household food preparation appliance in accordance with claim 5 , wherein rotating the measuring cap within the funnel varies the degree to which the steam release orifice is covered by the peripheral skirt.

7. A household food preparation appliance in accordance with claim 6 , wherein rotating the measuring cap reduces the passage cross-section of the steam release orifice from 0 to 50%.

8. A household food preparation appliance in accordance with claim 5 , wherein the peripheral skirt contains, on a separate angular section of the measuring cap, an extended section which descends lower than the remainder of the peripheral skirt.

9. A household food preparation appliance in accordance with claim 4 , wherein the funnel contains an internal wall in form of a cone extending inside the external wall and creates the opening to add ingredients and said internal wall forms a housing for the measuring cap.

10. A household food preparation appliance in accordance with claim 9 , wherein the measuring cap fits in the opening inside the internal wall of the funnel.

11. A household food preparation appliance in accordance with claim 1 , further comprising a control panel on a front face of the appliance and that the steam release orifice is oriented to a rear face of the appliance.

12. A household food preparation appliance in accordance with claim 1 , further comprising a basket for steam cooking which rests inside the working container.

13. A household food preparation appliance in accordance with claim 1 , the cover contains a watertight seal which rests against the working container when the working container is closed by the cover.
