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 dishwasher and method for operating the same utilize a diverter valve to control via rotation the flow of fluid such as wash fluid or pressurized air to a rotatable conduit supported in the rack of a dishwasher. A valve member may be disposed at a predetermined rotational position about an axis of rotation of the conduit such that a fluid inlet on a rotatable valve body may be rotated to the predetermined rotational position to restrict fluid flow to the conduit.

A dishwasher and method for operating the same utilize a check valve in a rotatable docking port to control the flow of fluid such as wash fluid or pressurized air to a rotatable conduit supported in the rack of a dishwasher.

A dishwasher and method for operating the same utilize a rack-mounted rotatable conduit with a return mechanism that positions the rotatable conduit to a predetermined rotational position when the conduit is disconnected from a docking arrangement on a wall of a wash tub.

A dishwasher includes a tub at least partially defining a treating chamber, at least one dish rack in the treating chamber, and a rack height adjustment assembly. The rack height adjustment assembly includes an adjuster plate slidably coupled to the at least one dish rack and fixed vertically relative to the tub, the adjuster plate including at least one adjuster detent, a locking lever having a catch end that is biased to engage the adjuster detent to hold the dish rack in place in either a lowered or raised position, the locking lever being pivotally movable relative to the at least one dish rack between an engaging position where the catch end engages the adjuster detent and a release position where the catch end does not engage the adjuster detent and the dish rack is vertically movable between the lowered and raised positions, and an actuator configured to move the locking lever to the release position when the actuator is moved from an undepressed position to a depressed position.

A retracting rack for an appliance such as a dish washing appliance. The rack may be positionable between a stowed position and a deployed position. A spring may drive the rack towards the stowed position. A locking mechanism may be used to secure the rack in one or more positions. A release mechanism and/or a reset mechanism may be used to control the retracting cycle of the rack.

A rack system for a cooking appliance cavity includes a first support unit including a plurality of rack support bars and a first connecting member defining a body portion having the support bars coupled therewith, a first end with a first post and a first stepped segment between the first post and the body portion, and a second end with a second post and a second stepped segment between the second post and the body portion. The system further includes first and second mounting blocks, each defining a channel and a notch extending intersecting with the channel such that a first portion of the channel is open and a second portion of the channel is enclosed. The first and second posts are respectively received in the second portions of the channels of the first and second mounting blocks.

A dishwasher is disclosed that may include a washing chamber, a rack, and a bracket. The rack may be slidably arranged in relation to the bracket to provide different vertical positions of the rack in relation to the washing chamber. The dishwasher may include a securing mechanism configured to secure the rack in relation to the bracket, in at least a first vertical position of the rack in relation to the washing chamber. The securing mechanism may include a protruding element and a tapered portion. The protruding element may be arranged to extend into the tapered portion when the rack is in the first vertical position. The tapered portion may be arranged to prevent movement of the protruding element through the tapered portion to secure the rack in relation to the bracket.

A dishwasher includes a tub at least partially defining a treating chamber. At least one dish rack defines an interior and is located in the treating chamber. At least one set of tines is located within the interior of the dish rack. A tine angle adjustment assembly includes an adjuster plate movably coupled to the at least one dish rack. The adjuster plate includes at least one adjuster pin. An adjusting arm operably couples the set of tines to the at least one adjuster pin.

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.
