Abstract: A home appliance, such as a laundry appliance, includes a component assembly with a sensor and a sensor-controlled component for operating the appliance, and a cover for housing the component assembly therein. The cover has an outer surface and an inner surface. The cover includes a functionalized superhydrophobic multi-layer coating on at least one of the outer surface and inner surface. The functionalized superhydrophobic coating prevents moisture from entering the component assembly and attacking sensors housed therein, and has a water contact angle thereon of at least 145 degrees.

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.

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.

Abstract: A dishwasher includes a housing having walls defining a tub having an outlet and inlet for humid air to flow out from and into the tub, respectively. A drying system contacts at least one wall of the tub. The drying system includes an inlet conduit fluidly connected to the outlet and an outlet conduit fluidly connected to the inlet with the inlet conduit and the outlet conduit forming an inverted V-shaped air circuit defining an airflow path therethrough. The drying system also includes at least one adsorbent component having an adsorbent material positioned along the airflow path, and at least one gate check valve blocking airflow from the tub to the adsorbent material during a wash cycle. The adsorbent material is regenerated via heat transfer through the at least one wall from the tub during a wash cycle when the gate check valve is closed.

Abstract: An appliance includes a housing defining an interior cabinet, a crisper drawer disposed therein, and a circulation system. The crisper drawer includes a base, walls, and lid defining a cavity, the lid selectively closing the drawer to limit air flow to and from the cavity. One or more of the base, the walls, and the lid define an opening for a humidity membrane disposed therein, sealed in the opening. The membrane includes nanofibers dispersed in a matrix to provide pervaporation across the membrane for airflow from the cavity to the interior cabinet. The circulation system cooperates with the membrane, and includes one or more fans disposed within the drawer to selectively facilitate air flow across the membrane and mix air within the cavity to control a humidity level within the drawer.
