OPERATION
Inductive zone – principles of operation
A power generator supplies the coil installed in the
heating panel. An induction coil is located under each
cooking zone. When a cooking zone is switched on, this
coil creates a magnetic field which impacts directly on
the base of the pan and heats it up. The cooking zone
itself is heated up indirectly by the heat given off by the
pan. The surface of the hob remains cold.
This requires the use of pots and pans whose base is ferromagnetic, in other words suscep-
tible to magnetic fields.
Overall, induction technology is characterized by two advantages:
●
the heat is only emitted by the cookware and its use is maximised,
●
there is no thermal inertia, since the cooking starts immediately when the pot is placed on
the hob and ends once it is removed.
Certain sounds can be heard during normal use of the induction hob, which do not affect its
correct operation.
●
Low-frequency humming. This noise arises when the cookware is empty and stops when
water is poured or food is placed in the cookware.
●
High-frequency whizz. This noise arises in cookware made of multiple layers of different
materials at maximum heat setting. The noise intensifies when using two or more cooking
zones at maximum heat setting. The noise will stop or reduce when heat setting is reduced.
●
Creaking noise. This noise arises in cookware made of multiple layers of different materi
-
als. The noise intensity depends on how the food is cooked.
●
Buzzing. Buzzing can be heard when electronics cooling fan operates.
The noises that can be heard during the normal appliance operation are the result of the cooling
fan operation, cooking method, cookware dimensions, cookware material and the heat setting.
These noises are normal and do not indicate a fault.
