ABSTRACT:
A heater for a washer-dryer includes a duct in which heating elements for heating the air flowing through the duct are disposed. A device for increasing the airflow in the area of a heating element is provided in the duct to improve the transportation of heat away from the heating element. The airflow device can be one or more projections on a wall of the duct extending into the duct and can be disposed upstream of the heating element with respect to a flow direction of the air, adjacent the heating element, and/or downstream of the heating element.
