Abstract

1,212,150. Laundry driers. A. MEYER. 16 Oct., 1969 [19 Oct., 1968], No. 50861/69. Heading F4G. A rotary drier comprises a rotatable perforated inner drum 4, a device to heat the damp articles contained in the inner drum, a rotatable outer drum 10 which surrounds the inner drum and is cooled on the inner surface by cooling liquid for condensing steam emerging from the inner drum, and a feed provided opening into the annular space formed between the inner drum and outer drum for introducing cooling liquid. The heating elements 14 and the cooling liquid feed pipe 16 are adjacent to one another and extend into the annular chamber 13 with the feed pipe spraying the liquid in the direction of rotation of the outer drum. Reflector surfaces 15 are situated between the heating elements and the outer drum shell to direct the thermal radiation on to the inner drum. The feed may be introduced coaxially to the drum and fed via a radial intermediate piece to the annular chamber. A collecting chamber is arranged around the aperture of the annular chamber, being fast with the housing and having an outwardly leading outlet pipe 19. The outer drum carries, at its rearward end, a sealing ring 25 abutting tightly against a side wall and/or the bottom surface of the collecting channel. A blower may be fitted to induce an air current, and/or the outer drum may be mounted and driven independently of the inner drum. The outlet pipe 19 may act as a water feed pipe to one or more washing machines, if necessary passing the water through the intermediary of a storage tank.
