Abstract
Assemblies for increasing airflow and heating efficiency in a multi-shelf food heating device having a base, a plurality of circular vertically stacked trays, and a top, wherein the airflow within the device is assisted by a fan is disclosed. One assembly involves a biasing system supported in the base for biasing the motor in place. Another assembly involves a thin, substantially planar constructed heater and a radial fan supported within a chamber of the base of the device, wherein the heater is aligned with the movement of the airflow within the chamber so that the airflow therein is substantially unobstructed by the heater. Another assembly involves providing the base with a wall substantially surrounding and adjacent an air inlet in the base to define a cavity into which substantially all of the airflow from the air inlet is directed, so that the motor is continuously cooled during operation of the device.
