  • the regulation process according to the invention consists in managing the supply of the heating elements 13 by via sensor 14 to obtain temperature regulation around a high TC threshold after a first steam subtraction of the boiler 12. Such a subtraction corresponds to the actuation of the excitation button 3 of the solenoid valve 15.

  • the generator according to the invention is brought directly to this operating state when the initial temperature of the metal tank 12a is higher or equal to the low threshold TB.
  • the method then consists in carrying out successive measurements by through the temperature sensor 14 which aims to calculate a value of slope D of a curve representative of the change in temperature of the boiler 12 and more particularly of the metal tank 12a.
  • the actuation of the pump 11 for a period determined as a function of the value of the slope D is thus a step in the process in accordance with the present invention. All stages are preferably controlled by the microcontroller 20.

  • the microcontroller 20 does not take account of the openings of the solenoid valve 15, of a duration less than the critical time to, corresponding for example to 1s. Successive temperature measurements or pressure are thus performed when the time t steam exhaust 2 of the boiler 12 exceeds the critical time to.
  • Figures 2a and 2b show on the one hand, examples of the durations t of opening of the solenoid valve 15 and on the other hand, the effects on the temperature T of the metal tank 12a. The measurements are preferably triggered 1 second after the opening of the solenoid valve 15.

  • the method then includes comparison steps.
  • Slope D is compared to values programmed in the microcontroller 20, to know a first slope D1 corresponding for example to a slope of 4.5 ° C / s and a second slope D2 corresponding for example to a slope of 2.25 ° C / s.
  • the microcontroller 20 When the slope D is greater than the value of D1 the microcontroller 20 ignores the measurements. This corresponds to an abnormal operating state.
  • the pump 11 When the slope D is between the values D1 and D2, the pump 11 is operated by means of a power supply control said pump 11.
  • the microcontroller 20 When, on the other hand, the slope D is less than the value D2, the microcontroller 20 performs a calculation of an average D on several values successive of slope D and compare said mean D to a third slope value D3 corresponding for example to 1.2 ° C / s.
  • the average D is greater than D3 the pump 11 is supplied, which allows introduce water into the boiler 12.
  • the value mean of the slope D is less than D3 the pump 11 is not supplied.
  • the regulatory process according to the invention therefore makes it possible to provide corrective values to the operating parameters of the generator steam by actuating the pump 11 almost instantaneously and even before that the temperature of the metal tank 12a reaches limit values. This is particularly advantageous and innovative in the context of this invention. Regulation is thus ensured dynamically.

  • the pump is turned on. runs and remains in operation for an initial duration t3, corresponding for example to 12s.
  • a next step is to compare the temperature T of the tank 12a, at a predetermined TE value. When the temperature is higher than the TE value, corresponding for example to 120 ° C, an additional step is to measure the time operation of the pump 11 since it was started, or time for market. This additional step takes place at most during a additional duration t4, corresponding for example to 20s. If the temperature remains greater than TE when the operating time reaches the duration t3 + t4, the operation of pump 11 is interrupted and an audible signal or visual is sent to the attention of the user. Such a situation corresponds to a tank 10 empty. On the other hand if the temperature drops below TE before the operating time reaches the duration t3 + t4, we proceed simply when the pump 11 stops, without additional signal.
  • the process according to the invention can thus be completed using a step consisting in cutting the operation of the pump 11, from a temperature measurement of the boiler 12 and a measurement of the time of operation of said pump 11.
  • the stopping of the pump 11 is caused by a succession of steps relating to an analysis of the slope D.

Steps consist in measuring Tl, measuring during time t7 the duration of opening of the solenoid valve 15, measure when the time t7 is reached the final temperature TF, calculate the slope D corresponding to the difference between the temperature initial Tl and final temperature TF, then as a function of slope D and advantageously from the initial temperature T1, stop the pump 11.
  • the process according to the invention can thus be completed with a step consisting in cutting the operation of the pump 11, from an analysis the slope D, the initial temperature Tl and a measurement of the time of operation of said pump 11.
