Abstract: A laundry treating appliance comprising a chassis defining an interior with at fixed tub disposed in the interior, the tub defining a liquid chamber. An exoskeleton is disposed within the liquid chamber and houses a drum defining a treating chamber for treating laundry. A suspension comprising one or more suspension component mounts the exoskeleton to that chassis through an opening in the tub. The interior is sealed from the liquid chamber by a plurality of seals at the openings and suspension components extending through the openings, preventing liquid from spilling into the interior from the liquid chamber.

Abstract: A laundry appliance includes a cabinet defining an aperture in a front surface thereof. A drum is disposed within the cabinet. The drum defines an access opening that aligns with the aperture. A door is coupled to the cabinet and is operable between closed and opened positions relative to the aperture. A bellows extends along a perimeter of the aperture and proximate the access opening. A deflector extends along at least a portion of the perimeter of the aperture. The deflector extends into an interior of the drum over the bellows.

Abstract: A washing machine may include a static wash tub, a rotatable vertical axis wash basket in the static wash tub, and a drive motor for rotating the wash basket. A closure may direct wash liquid from the wash basket to a catch basin. A flange may be attached to the closure so that an unattached edge ends within the catch basin. The unattached edge may end below the surface of a first volume of wash liquid to minimize migration of wash liquid and/or vapor from the washing machine. The unattached edge may end above the surface of a second volume of wash liquid less than the first volume to minimize agitation of wash liquid in the catch basin.

Abstract: A laundry treating appliance is configured to treat laundry according to a cycle of operation. The laundry treating appliance comprises a chassis that defines an interior and has a front and rear with an access opening located in the front. A tub statically mounted to the chassis and defines a liquid chamber located within the interior and has at least one suspension opening. An exoskeleton is located within the liquid chamber and has a front support, a rear support, and stringers extending longitudinally to form a skeletal frame defining a frame interior. A rotatable drum is located within the frame interior. A suspension system is located within the interior and has at least one suspension component extending into the liquid chamber through the suspension opening and is operably coupled to the exoskeleton. A liquid dam retards liquid flow from the liquid chamber to the interior through the suspension opening.
