4. FUNCTIONING:
The water contained in a removable tank is brought by a solenoid valve on a heat generator where it is
transformed into steam.
The steam obtained is maintained in the oven cavity by closing a valve at the beginning of a cooking
program.
This valve is bored in order to avoid the pressurization of the cavity.
This cooking principle is different to a pressure-cooker where the obtained pressure is higher than the
atmospheric one.
Initially the oven will be saturated with steam and the temperature will be close to 100°C.
In order to avoid condensation, an heating cover which covers the top will be supplied during all cooking
time.
A tangential fan allows the constant cooling of the oven and the extraction of the steam when the flap opens
three minutes before the end of the cycle.
A safety thermostat (210°C) protects the oven against overheating.
Two sensors placed in the cavity and in the generator allow the temperature control.
