ABSTRACT:
An electric clothes dryer has an irregular polygonal shaped rear wall where the apexes in the polygon align readily with the center of the heater housing to define positions where the electrical insulators are mounted to the heater housing rear wall. Raised land pads are formed from the rear wall of the heater housing at these locations and on which the insulators are mounted. The raised land pads further have radial slots that permit airflow from beneath the pad into the heater housing and across the insulator and the heating element. The apexes further provide an increased air gap for increased airflow radially across the electrical insulators. The heater housing has an air gap with the rear end head of the dryer drum which air gap is smaller adjacent the upper portions of the heater housing so as to reduce the chimney effect associated with the air heated in the heater housing.
