Abstract

A household cooking utensil includes a first control member ( 9 ) mounted to move between a plurality of positions to enable the user to act on operation of the utensil. In addition, an information device ( 60 ) connected to the first control member ( 9 ) is configured to emit a signal corresponding to a first predetermined position of the first control member ( 9 ). The information device ( 60 ) and the first control member ( 9 ) are interconnected, for emitting the signal, via at least one sensor ( 10, 11, 12 ) and via an activator ( 13 ) which excites at least one sensor ( 10, 11, 12 ) remotely when the first control member ( 9 ) occupies the first predetermined position. Utensils for cooking food.

First claim

What is claimed is:

1. A household cooking utensil ( 1 ) having firstly at least a first control member ( 9 ) mounted to move between a plurality of positions and configured to enable the user to act on operation of said utensil ( 1 ), and an information device ( 60 ) connected to said first control member ( 9 ) and configured to emit a signal ( 70 ) of audible and/or visible nature that is characteristic of at least a first predetermined position of said first control member ( 9 ), said information device ( 60 ) and said first control member ( 9 ) being interconnected, via at least one sensor ( 10 , 11 , 12 ) and via at least one activator ( 13 ) configured to excite said sensor ( 10 , 11 , 12 ) remotely when the first control member ( 9 ) occupies said first predetermined position, so that the first control member ( 9 ) reaching its first predetermined position causes said information device ( 60 ) to emit said signal ( 70 ), said utensil ( 1 ) being constituted by a pressure cooker comprising a vessel, a lid, locking/unlocking means for locking/unlocking the lid relative to the vessel to form a cooking enclosure, and a regulator valve ( 5 ) for regulating the pressure inside the enclosure at a first predetermined value, the first control member being configured to include at least one of the following (i) and (ii): (i) control the regulator valve ( 5 ) and is mounted to move between at least (a) a decompression position, in which the inside of the enclosure is put into communication with the outside, for enabling the pressure prevailing inside the cooking enclosure to be brought back to or maintained at a value compatible with safe unlocking of the lid ( 3 ), and (b) a first cooking position allowing pressure to build up inside the cooking enclosure to said first predetermined value regulated by the regulator valve ( 5 ); and (ii) control the locking/unlocking means for enabling the user to act on the lock/unlocking of the lid relative to the vessel.

2. A utensil ( 1 ) according to claim 1 , wherein said activator ( 13 ) is incorporated in the first control member ( 9 ).

3. A utensil ( 1 ) according to claim 1 , wherein said sensor ( 10 , 11 , 12 ) is incorporated in the information device ( 60 ).

4. A utensil ( 1 ) according to claim 1 , wherein said sensor ( 10 , 11 , 12 ) is a magneto-resistive sensor.

5. A utensil ( 1 ) according to claim 4 , wherein said sensor ( 10 , 11 , 12 ) is a sensor of the C-MOS type.

6. A utensil ( 1 ) according to claim 4 , wherein said activator ( 13 ) comprises a magnet.

7. A utensil ( 1 ) according to claim 1 , wherein said information device ( 60 ) and said first control member ( 9 ) are interconnected via:
a plurality of sensors ( 10 , 11 , 12 ); and
a single activator ( 13 ) to excite selectively one or more of said sensors ( 10 , 11 , 12 ) as a function of the position of the first control member ( 9 ).

8. A utensil ( 1 ) according to claim 1 , wherein the utensil is constituted by a pressure cooker comprising a vessel and a lid ( 3 ) to be locked on said vessel to form a cooking closure therewith.

9. A utensil ( 1 ) according to claim 8 , wherein the first control member ( 9 ) permits the user to act on the pressure level prevailing inside the cooking enclosure.

10. A utensil ( 1 ) according to claim 9 , characterized in that it wherein the utensil ( 1 ) has a second control member ( 6 ) configured for the user to act on the locking/unlocking of the lid ( 3 ) relative to the vessel, said second control member ( 6 ) being distinct from the first control member ( 9 ).

11. A utensil ( 1 ) according to claim 9 , wherein the first control member ( 9 ) is mounted to move between at least firstly an opening position enabling the pressure prevailing inside the cooking enclosure to be brought back to or maintained at a value compatible with safe unlocking of the lid ( 3 ), and secondly at least one cooking position allowing pressure to build up inside said cooking enclosure to a pressure level incompatible with safe unlocking of the lid ( 3 ).

12. A utensil ( 1 ) according to claim 11 , wherein the information device ( 60 ) emits an alarm signal so long as the first control member ( 9 ) is in the opening position.

13. A utensil ( 1 ) according to claim 9 , wherein the information device ( 60 ) comprises firstly detection means for detecting when a predetermined pressure value is reached inside the enclosure, and secondly a timer functionally linked to said detection means so as to trigger said timer as soon as it is detected that said predetermined pressure value has been reached.

14. A utensil ( 1 ) according to claim 1 , wherein the information device ( 60 ) further comprises a display screen ( 61 ) that displays at least one sign corresponding to said signal ( 70 ) characteristic of the first predetermined position of said first control member ( 9 ).

15. A utensil ( 1 ) according to claim 3 , wherein said sensor ( 10 , 11 , 12 ) is a magneto-resistive sensor.

16. A utensil ( 1 ) according to claim 5 , wherein said activator ( 13 ) comprises a magnet.

17. A utensil ( 1 ) according to claim 10 , wherein the first control member ( 9 ) is mounted to move between at least firstly an opening position enabling the pressure prevailing inside the cooking enclosure to be brought back to or maintained at a value compatible with safe unlocking of the lid ( 3 ), and secondly at least one cooking position allowing pressure to build up inside said cooking enclosure to a pressure level incompatible with safe unlocking of the lid ( 3 ).

18. A utensil ( 1 ) according to claim 10 , wherein the information device ( 60 ) comprises firstly detection means for detecting when a predetermined pressure value is reached inside the enclosure, and secondly a timer functionally linked to said detection means so as to trigger said timer as soon as it is detected that said predetermined pressure value has been reached.

19. A utensil ( 1 ) according to claim 11 , wherein the information device ( 60 ) comprises firstly detection means for detecting when a predetermined pressure value is reached inside the enclosure, and secondly a timer functionally linked to said detection means so as to trigger said timer as soon as it is detected that said predetermined pressure value has been reached.

20. A utensil ( 1 ) according to claim 12 , wherein the information device ( 60 ) comprises firstly detection means for detecting when a predetermined pressure value is reached inside the enclosure, and secondly a timer functionally linked to said detection means so as to trigger said timer as soon as it is detected that said predetermined pressure value has been reached.
