Abstract
An electrically heated dryer for articles comprises a drying container and an air duct leading thereto for directing air in a stream through the duct and into the container. An electric resistance heating element is provided in the duct and comprises an expanded resistance metal sheet of separated strands and connecting bridges with the strands at an angle to the sheet and generally parallel to each other. The element is serpentively arranged in the duct in successive substantially planar reaches spanning the duct with the strand surfaces of the upstream reaches arranged substantially parallel to the direction of air flow for streamline wiping action thereof by the air stream. A planar reach downstream of said upstream reaches is arranged with its strand surfaces substantially non-parallel to the direction of air stream flow to aid in mixing the heated air prior to delivery into the container.
