Abstract
Abstract Condenser apparatus for removing moisture from the air including a housing for the condenser apparatus, which housing has both a cooling liquid inlet and an air inlet at one end. Within the housing is a condensing chamber and a rotatable disc spaced inwardly from the liquid inlet so that when the disc is rotated and liquid is impinged upon the disc a cooling liquid droplet cloud is produced in the condensing chamber. At the opposite end of the condenser housing from the inlet is an air outlet and a concentrically positioned rotatable blower. Located between the blower and the rotatable disc is a rotatable liquid droplet interceptor wheel for collecting entrained liquid droplets before they pass into the blower and deposits them into an underlying bath. Circumferentially around the interceptor wheel is a liquid pump that removes liquid from the condenser apparatus. An electric motor is utilized for rotatably driving all of the rotating elements. The condenser apparatus is utilized particularly in an automatic clothes dryer wherein hot moistureladen air that has been passed over the fabrics to be dried is introduced into the condenser apparatus which reduces the temperature of the air to condense moisture therefrom and then recirculating the air again through the clothes dryer.
