  • Publication number: 20230002955
    Abstract: A dryer appliance includes a distribution system for directing treatment fluids into a dryer chamber. The treatment fluids are transported from a reservoir and directed onto a heating surface above a heating element, where the treatment fluids are evaporated. A negative pressure is generated by a blower that draws ambient air through a heater housing around the heating element and heating surface, thus mixing the ambient air with the evaporated treatment fluids. This mixture is then directed into the drying chamber, where the articles to be treated are present.

  • Publication number: 20220228311
    Abstract: A washing machine includes a cabinet defining a lateral direction, a transverse direction, and a vertical direction. The lateral, transverse, and vertical directions are mutually orthogonal. The washing machine appliance also includes a top panel on the cabinet that defines an opening. A wash chamber is defined within the cabinet below the opening of the top panel. The washing machine appliance also includes a lid which is rotatable through a plane defined by the transverse direction and the vertical direction between a closed position to sealingly enclose the wash chamber and an open position to permit access to the wash chamber. A hinge rotatably connects the lid to the top panel. The hinge defines a compound pivot axis. The lid rotates relative to the top panel about the compound pivot axis.
