Theory Of Operation; Air Flow - KitchenAid KEBI141D Technical Education

Intake air is drawn into the oven at two loca-
tions: through the control panel vent, (over the
latch assembly and the inner chassis top), and
through the side mounting rails (over the oven
sides and around the back). Air also enters the
oven at the back through the openings on the
upper section of the rear cover. At this point,
the air from the sides and the top mix. The air
is then pulled through the blower, down the
back of the unit between the outer and inner
rear covers, and out the front of the unit via the
bottom vent trim.
Air from the blower is forced over the cavity
vent. The pressure differential causes air to be
drawn from the cavity, where the air exits
through a small opening on the left side of the
control panel vent.

THEORY OF OPERATION

AIR FLOW

Air passes through the oven door by a combi-
nation of natural and forced convection. Air
enters the door through the bottom slots, and
passes between the outer glass, and the angled
inner glass. This air exits through the top slots
in the door via natural convection. Air also
enters the bottom of the door, and is drawn
between the two pieces of inner door glass,
where it exits through the top slots in the upper
part of the door. This air is then drawn into the
blower, and is forced down the back of the unit
between the inner and outer chassis covers,
and finally out the bottom vent.
The purpose of the convection fan is to circu-
late hot air inside the oven cavity, not to evacu-
ate the air. Thus, the air flow for the convection
models and the non-convection models, is the
same.
