Method for controlling power supply to the liquid contents of a cooking vessel
A method for controlling power supply to the liquid contents of a cooking vessel or the like, particularly for controlling the electrical power supply in an induction heating system, wherein a predetermined thermodynamic state is detected and the user is alerted, comprises maintaining a predetermined high power condition after reaching the predetermined thermodynamic state for a predetermined time and then reducing the power supply to a predetermined level.
1. A method for controlling power supplied to liquid contents of a cooking vessel during a cooking operation comprising:
controlling an electrical power supply in a heating system;
automatically detecting a first predetermined thermodynamic state associated with the liquid contents;
alerting a user when the first predetermined thermodynamic state is detected;
maintaining a high power condition after reaching said first predetermined thermodynamic state for a predetermined period of time; and
subsequently, automatically reducing the electrical power supply to a predetermined level below the high power condition.
2. The method according to claim 1 , wherein the first predetermined thermodynamic state constitutes when the liquid contents starts to boil.
3. The method according to claim 1 , wherein the first predetermined thermodynamic state is a predetermined temperature.
4. The method according to claim 1 , further comprising: reducing the electrical power supply according to a predetermined pattern.
5. The method according to claim 1 , further comprising: detecting an introduction of food into the cooking vessel before maintaining the high power condition.
6. A method for controlling power supplied to liquid contents of a cooking vessel during a cooking operation comprising:
controlling an electrical power supply in a heating system;
automatically detecting a first predetermined thermodynamic state associated with the liquid contents;
alerting a user when the first predetermined thermodynamic state is detected;
detecting an introduction of food into the cooking vessel;
maintaining a high power condition after the introduction of food into the cooking vessel and after reaching said first predetermined thermodynamic state for a predetermined period of time;
subsequently, automatically reducing the electrical power supply to a predetermined level below the high power condition;
detecting a second predetermined thermodynamic state of the liquid contents;
counting time starting from reaching the second predetermined thermodynamic state to generate a counted time; and
displaying the counted time to the user.
7. The method according to claim 6 , further comprising: alerting the user when the second predetermined thermodynamic state is reached.
8. The method according to claim 6 , further comprising: interrupting the electrical power supply at a certain predetermined time, after the second predetermined thermodynamic state is reached, according to data selected by the user.
9. The method according to claim 1 , wherein the predetermined time period is a time period necessary for the user to insert food into the cooking vessel.
10. The method according to claim 1 , wherein the predetermined period of time is thirty seconds.
