Abstract (en)

[origin: FR2903761A1] The process of detection of vacuum functioning of a vapor generator (12), comprises detecting a phase of absence of water in the generator during the blow of temperature regulation unit of the generator. The generator comprises a unit to heat and vaporize the water, a unit for circulating the water and a temperature regulation unit, and is connected to an external source of water supply. The ratio of the duration of blow during the mode of vacuum functioning over the duration of blow during the mode of supplying water is 5/1-15/1. The duration of vacuum functioning is 20 seconds. The process of detection of vacuum functioning of a vapor generator (12), comprises detecting a phase of absence of water in the generator during the blow of temperature regulation unit of the generator. The generator comprises a unit to heat and vaporize the water, a unit for circulating the water and a temperature regulation unit, and is connected to an external source of water supply. The ratio of the duration of blow during the mode of vacuum functioning over the duration of blow during the mode of supplying water is 5/1-15/1. The duration of vacuum functioning is 20 seconds, and the duration of the phase detection in the vapor generator is 2 minutes. Number of engaging of temperature regulation unit is counted during the phase detection of water in the generator. An alert system is used for functioning the phase detection of water. An average power supplied to the vapor generator during the vacuum functioning is lower than 50 watts. Independent claims are included for: (1) a dry machine; and (2) a cooking furnace.
