The present disclosure relates to a dishwasher having a structure improved in convenience of use. The dishwasher includes a tub having a front opening and a top opening, a front door configured to open and close the front opening, a cover frame disposed on the top opening and including an opening opened in the up-down direction, a top door configured to open and close the opening of the cover frame, and a frame injector disposed on the cover frame to inject washing water from one side of the cover frame.

A dishwasher utilizing one or more sprayer rings disposed proximate to one or more tines of a dishwasher rack, where the sprayer ring(s) are in fluid communication with a fluid supply that is configured to supply a fluid to the one or more sprayer rings to spray fluid onto utensils disposed within the wash tub.

A dishwasher with a tub that at least partially defines a treating chamber with an access opening, a closure moveable relative to the tub to selectively open and close the access opening, a lower dish holder located within the treating chamber, a middle dish holder located within the treating chamber above the lower dish holder, and an upper dish holder located within the treating chamber above the middle dish holder and having container supports defining a support surface.

A method and apparatus of a docking port arrangement for an adjustable dispensing device. The dispensing device may discharge a fluid and/or gas into the wash chamber. The dispensing device may be retracted into the wash chamber and extended out of the wash chamber. A gasket or portions thereof may be used for sealing and/or as an abutting structure during retraction into the wash chamber. The dispensing device may be, but is not limited to, a rotating spray arm. Two check valves may pivot together relative to a check valve plate.

A utensil basket for removable mounting in a dishrack of a dishwasher having a liquid distribution system. The utensil basket having a housing with an open top and a porous bottom, multiple seats provided within the housing, a utensil separator, and a sprayer carried by the housing and configured to emit a spray of liquid toward the multiple seats.

An adjustable conduit and docking assembly for use in a dishwasher appliance is provided. The adjustable conduit and docking assembly includes a conduit configured for receiving a docking station at different heights so as to accommodate a height adjustment of a rack assembly to which the conduit is attached. The conduit and docking assembly includes a multiport docking station to provide this functionality.

A method and a dishwasher utilize a dock detection system to determine when a connector of a spray device is docked to a docking port provided on a manifold of the dishwasher. A dock detector is coupled to the docking port and is electrically coupled to a controller of the dishwasher through electrical conductors that extend along the manifold, thereby enabling a dishwasher controller to detect when spray devices are coupled to the manifold, e.g., to optimize a wash cycle to use a particular spray device docked to the docking port.

A dishwasher and method for operating the same utilize a docking arrangement for an elevation-adjustable rack. In some instances, a docking arrangement may include one or more rotatable docking ports to rotate a rotatable conduit supported on the rack, and in some instances, a docking arrangement may include a valve body disposed within a docking port and movable between open and closed positions in a direction generally parallel to an axis of insertion of a conduit into a docking port in response to rotation of a drive.

A load carrier (1) for a cleaning machine is proposed. The load carrier (1) comprises a carrying frame with a lower load carrier tier (2) and an upper load carrier tier (3) which are arranged parallel to one another and which are connected to one another by spacers (5, 6). Furthermore, the load carrier (1) comprises at least one further, removable load carrier tier (11) which, parallel to the upper and lower load carrier tiers (2, 3), is detachably fastened to, preferably slidable into, the carrying frame. The removable load carrier tier (11) comprises a rotatably mounted wash arm (10) and at least one feed line (8) for the supply of a fluid to the wash arm (10).

A dishwasher and method for operating the same utilize a docking arrangement for an elevation-adjustable rack. In some instances, a docking arrangement may include one or more rotatable docking ports to rotate a rotatable conduit supported on the rack, and in some instances, a docking arrangement may include a valve body disposed within a docking port and movable between open and closed positions in a direction generally parallel to an axis of insertion of a conduit into a docking port in response to rotation of a drive.
