Abstract: A dishwasher includes a housing having walls defining a tub with an outlet for humid air to flow out from the tub and an inlet for dry air to flow into the tub. The dishwasher also includes a drying system with a fluidized bed containing an adsorbent material, and an air circuit for supplying air to fluidize the adsorbent material via an air inlet, with at least a portion of the air inlet in contact with at least one wall of the tub such that heat is transferred from the tub to the air. During a regeneration cycle, the air circuit supplies heated ambient air to the fluidized bed to regenerate the adsorbent material. During an adsorption cycle, the air circuit receives hot humid air from the tub to be dried by the adsorbent material through the fluidized bed and returned as dry air to the tub.
