Abstract: A washing machine is disclosed that comprises an enclosure for receiving a cart to be washed. A main shuttle assembly is movable vertically on vertical guides and carries a fan for passing drying air over a heater and projecting it from a slot toward the cart in the form of a flat horizontal jet of air. The main shuttle assembly also carries washing manifolds, opposite second washing manifolds carried by a secondary shuttle assembly that is itself mobile vertically. The shuttle assemblies are driven by pulleys at the top. The washing enclosure is associated with a dehumidifier center located above its ceiling for drying the air inside the washing enclosure during drying steps. Carts are therefore dried faster and leave at a lower temperature allowing their immediate manipulation.
