Abstract

A clothes dryer is adapted to reduce residual static in clothing items. The sidewall of the drum carries conductive tumbling vanes and a conductive projection. The vanes engage clothing items at the periphery of the dram interior. The projection penetrates further into the drum to contact clothing items that tend to locate there when the dryer is very full. The projection curves in the direction of drum rotation to avoid trapping clothing against the drum side wall. The vanes and projection are coupled to the ground terminal of an electrical main to dissipate static charges gathered from the clothing. To enhance electrical coupling to the rotary drum, a copper ring is mounted around the drum and a copper contact plate is supported from the dryer housing and spring-biased to engage the copper ting. Residual static is further reduced with a grounded conductive plate located near the bottom of the dryer opening that accesses the drum. The conductive plate defines an upward arcuate projection centered horizontally relative to the dryer opening and a recess to either side of the projection so that clothing items are spread across its conductive surface as they are dragged through the dryer opening.
