Dish drying system with water harvesting hybrid nanomaterial

A dishwasher comprising:

• a sprayer;
• a housing having walls defining a tub with a tub outlet for humid air to flow out from the tub, and a tub inlet for dry air to flow into the tub;
• and
• a drying system including:
• an air circuit positioned outside of an interior volume of the tub and adjacent to at least one side wall of the tub, the air circuit having an air inlet toward an upper end of the tub for flowing the humid air into the air circuit, and an air outlet connected to the tub inlet to flow dried air to the tub at a lower end of the tub, the air circuit defining a vertical airflow path adjacent to the at least one side wall between the upper end and the lower end,
• an adsorbent component disposed between the air inlet and the air outlet within the vertical airflow path and against the at least one side wall of the tub between the upper end and the lower end such that air flows downward over the adsorbent component within the vertical airflow path of the air circuit, the adsorbent component including a water harvesting nanomaterial for absorbing water from the humid air when the air flows downward over the adsorbent component and releasing water upon regeneration, and
• a valve operatively coupled to the air circuit,
• wherein, during a drying cycle, the air circuit draws humid air from the tub via the air inlet such that the adsorbent component absorbs moisture from the humid air to form a dry air stream through the vertical airflow path, and during a subsequent wash cycle, the valve operatively coupled to the air circuit is controlled to be closed and the air circuit is blocked from receiving air flow from the tub such that latent heat is transferred to the adsorbent component via conduction through the at least one side wall and convection within the vertical flow path of the air circuit, to regenerate the water harvesting nanomaterial.
