Abstract
A dishwasher includes 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; and a drying system with an air circuit and an adsorbent component disposed between an air inlet and an air outlet in the air circuit. The adsorbent component includes a water harvesting nanomaterial for absorbing water from the humid air and releasing water upon regeneration. During a drying cycle, the air circuit draws humid air from the tub such that the adsorbent component absorbs moisture from the humid air to form a dry air stream, and during a subsequent wash cycle, the air circuit is blocked from receiving air flow such that latent heat can be transferred to the adsorbent component via conduction, convection, or both, to regenerate the water harvesting nanomaterial.
