5.4. Combination cooking control
Combination cooking is accomplished by operating the
microwave
and
heater
mode
alternately
during
one
combination cooking cycle.
There are 2 combination mode:
1. Grill combination (Grill + Microwave)
2. Convection combination (Conv Microwave)
1. The digital programmer circuit generates the power relays
control signals at a specific timing as shown in figure.
2. When the oven temperature reaches the predetermined
temperature, the digital programmer circuit stops supplying
power relays control signals resulting in heaters to turn off.
During this, digital programmer circuit continues supplying
power relay 1, 3 contol signal so that microwave activity
continue at predetermined duty ratio as shown in figure.
The microwave activity continue to cycle until entire cooking
programme is completed.
3. When the oven temperature drops below the selected
temperature, the digital programmer circuit generates
power
relays
contol
signals
again
at
the
timing
predetermined.
NOTE 1:
After combination process, if oven temperature is higher
than predetermind temperature, fan motor rotates for 5
minutes at maximum time to cool the electric components
and oven.
