3.1. OVEN COOLING CIRCUIT AND FLUE
The oven is cooled by a tangential fan motor located above the oven cavity
The tangential cooling starts working (regardless of which cooking operation is selected) when the oven is switched on. The fan pro-
duces an air flow that lows out from an opening between the door and the front panel. The cooling air flow may also continue for a
short time after the oven is switched off.
Diagram of the air flow
Fresh air is sucked in by the tangential fan A at the bottom part
of the oven, passes through the door via the slit u nderneath
and in the back of the oven.
After circulating in the purposely designed ducts, it is captured
by the tangential fan a nd expelled from the front o pening
between the door and the front panel.
The cooling fan can work at two different speeds: full speed (only during the pyrolytic cycle) and half speed (normal operation). The
half speed operation is achieved by means of a load resistor connected series on the motor supply circuit.
Venting of the humidity from the oven cavity is achieved by means of a flue chimney connecting the cavity ceiling to the upper duct
of the cooling circuit.
