The cooking device has a tank with an electrical heater means containing a basket for the food connected to an actuator suitable for moving it between a position inside and a position at least partially outside the tank. A first temperature sensor of a portion of the tank and a timer are connected to a control for moving the basket in relation to the signals which the control receives from the temperature sensor and from the timer. In the cooking procedure when the first sensor detects the cooking temperature, the basket is lowered and, at the same time, the timer is started for a preset time period. At the end of the time period the control deactivates the heater and commands the removal of the basket from the tank.

The cooking device according to claim 8 wherein said second and third sensors are microswitches. 10. The cooking device according to claim 9, further comprising a guide for the translation of said actuation means. 11. The cooking device according to claim 10 wherein said second and third sensors and said second motor lie in a misaligned position with respect to a translation axis of said actuation means. 12. The cooking device according to claim 11 wherein said guide defines a shell suitable for protecting, inside of it, said support and said cursor, and suitable for supporting, on the outside, said second and third sensors and said second motor. 13. The cooking device according to claim 12 wherein that said shell is open on the side facing said tank. 14. The cooking device according to claim 8 wherein said tank is removably connected to said body. 15. The cooking device according to claim 14 which has a counter tank which houses said tank inside of it. 16. The cooking device according to claim 15, further comprising at least one fourth sensor of the presence of said tank. 17. The cooking device according to claim 1, further comprising a first lid applied onto said basket. 18. The cooking device according to claim 17 wherein said first lid has at least one first and one second positioning hole for long pasta suitable for holding said long pasta in a suitable position for stirring. 19. The cooking device according to claim 18 wherein said first lid has at least one third hole in which a container is housed suspended in said basket. 20. The cooking device according to claim 19 wherein said container extends below with a fixed anti-rotation vane of the pasta. 21. The cooking device according to claim 20 in that said tank has an upper edge that is raised with respect to an upper edge of the counter tank. 22. The cooking device according to claim 21 wherein, between the upper edge of said tank and the upper edge of said counter tank a deviation ring is arranged suitable for deviating cooking liquid possibly escaping from said tank outside of said counter tank. 23. The cooking device according to claims 22 wherein said deviation ring is held in a flap of the upper edge of said tank wherein at least one grip of said tank extends from said deviation ring. 24. The cooking device according to claim 23, further comprising a second lid applied over said first lid. 25. The cooking device according to claim 24 wherein said second lid extends radially beyond the shaping of said tank and has a peripheral edge which rests in a seat of said grip of said tank. 26. The cooking device according to claim 15, further comprising a protective element for said first motor placed between said first motor and said counter tank. 27. The cooking device according to claims 1 wherein a side wall of said basket has a plurality of calibrated holes suitable for redirecting the cooking liquid rising through a space between said basket and said tank back inside said basket. 28. The cooking device according to claim 27 wherein said plurality of calibrated holes of the basket is present at least in a zone of the side wall of said basket facing a zone of the tank most heated by said electrical heating means. 29.
