Ventilation system for cooking appliance

Abstract:

A cooking appliance includes a housing having a heating cavity defined therein, wherein a heat source is in thermal communication with the heating cavity. A cooling channel is disposed proximate a sidewall of the housing. A blower selectively operates to move at least cooling air through the cooling channel and to an air outlet. A vent aperture extends through the sidewall between the heating cavity and a ventilation channel. The ventilation channel includes a narrowed portion proximate the vent aperture, wherein during operation of the blower, the narrowed portion defines a low static pressure region of the ventilation channel that draws cavity air from the heating cavity and directs the cavity air into the ventilation channel to be combined with the cooling air.
