A dishwasher may include a basket; tubing at the bottom of the basket; at least one utensil holder rotatably connected to the tubing and rotatable between an operating positionl, in which an article can be held at the utensil holder, and a resting position, in which the utensil holder is stowed away when not in use; and a nozzle communicating with the tubing and located to direct a jet of washing liquid towards an article held at the utensil holder. The utensil holder may include a clamping portion adapted to engage an article to be cleaned, and the nozzle may be located in proximity of the clamping portion. The utensil holder may include a valve means which provides for fluid communication between the tubing and the nozzle in the operating position, and which may block the fluid communication between the tubing and the nozzle in the resting position.

Dishwasher

A method, system, and computer-program product for preventing overfilling in a dishwasher are disclosed herein. According to one embodiment, a method for preventing overfilling in a dishwasher is provided, wherein the dishwasher includes a water valve for providing water to the dishwasher and a drain pump for removing water from the dishwasher. The method comprises detecting an overfill condition in the dishwasher with at least one detection device, wherein the overfill condition corresponds to a water level in the dishwasher that is greater than a predetermined threshold. The method further includes controlling the drain pump and the water valve in response to detecting the overfill condition in order to facilitate removal of the overfill condition.

Method for operating a shortened dishwashing cycle of a dishwasher, dishwasher configured for running the shortened dishwashing cycle and computer program product for operating a shortened dishwashing cycle of a dishwasher. The dishwasher () includes a tub () configured to hold dishware during a dishwashing cycle, at least one circulation pump (), at least one heating element (), and a controller () configured to operate the dishwasher. The controller () is configured to operate the dishwasher () according to at least one of a normal dishwashing cycle or the shortened dishwashing cycle. The method includes providing a first amount of warm water to the tub (). The first amount of warm water is greater than a standard amount of water provided to the tub () for the normal dishwashing cycle. The method further includes, while the first amount of warm water is being provided into the tub (), pulsing the circulation pump () based on a predetermined timing sequence and activating the heating element () to heat the water within the tub ().

Methods, systems, and apparatuses for performing a quick cycle in a dishwasher

According to embodiments of the present invention, a dishwasher may provide an intensified wash effect. The dishwasher may include a rack defining a bottom and a sidewall, wherein the rack is adapted to receive dishware therein. A dishwashing fluid supply channel may be configured to supply dishwashing fluid to a spray assembly. The spray assembly may comprise at least one nozzle member. Thereby, the spray assembly may be adapted to receive the dishwashing fluid from the dishwashing fluid supply channel and to dispense the dishwashing fluid therethrough. The spray assembly may be coupled to the sidewall of the rack. Further, the nozzle member may be attached to an arm which is moveable between at least a first position wherein the arm is adjacent the sidewall of the rack and a second position wherein the arm is adjacent the bottom of the rack.

According to example embodiments, a dishwasher may include a siphon break apparatus configured to substantially prevent a siphon effect in a fluid conduit configured to drain a fluid from the dishwasher. The siphon break apparatus may include a first check valve in fluid communication with the fluid conduit and exposed to a pressure therein and a second check valve in fluid communication with the first check valve. The first and second check valves may be configured to be substantially closed when pressure in the fluid conduit increases as a result of fluid being pumped through the fluid conduit and substantially open when pressure in the fluid conduit decreases as a result of the fluid no longer being pumped through the fluid conduit. Thereby the siphon effect may be substantially prevented.

Embodiments of the present invention relate to methods and systems for detecting and removing a clogging condition of a filter in a dishwasher. According to one embodiment, the method includes determining a normal water level or a normal rate of water level change for a wash cycle of the dishwasher and monitoring a water level or a rate of water level change during execution of the wash cycle. The method further includes detecting the clogging condition of the filter by detecting a deviation thereof. A current position of the wash cycle being executed may then be determined. The method further includes executing a remedial operation to facilitate removal of the clogging condition and determining if the clogging condition has been removed. Finally, the method includes resuming operation of the dishwasher at a wash cycle position based on the current position if the clogging condition has been removed.

Embodiments of the present invention are related to a detergent dispenser configured to attach to an interior surface of a dishwasher door. The detergent dispenser may comprise a reservoir configured to hold detergent, wherein a portion of the upper wall of the reservoir has been removed to reduce a cross-sectional length thereof such that water flowing down the dishwasher door is encouraged into the reservoir. The detergent dispenser may also comprise a dispenser door comprising a closed configuration and an open configuration, wherein the dispenser door is configured to cover the reservoir in the closed configuration. The detergent dispenser may be configured to encourage water flowing down the interior surface of the dishwasher door to enter the reservoir when the dispenser door is in the open or closed configuration.

A filtration system for a dishwasher, and an associated apparatus and method, are provided, comprising a macerator chamber adapted to house a macerator device. The macerator chamber is configured to receive washing fluid for the macerator device to comminute contaminants within the washing fluid. A drain chamber is in fluid communication with the macerator chamber and is configured to receive the washing fluid and comminuted contaminants therefrom via a fluid port therebetween. The drain chamber has a vented member associated therewith, which defines at least one first vent providing fluid communication between the drain chamber and the washing fluid circulation system. The vented member is spaced apart from the fluid port, and is configured to strain the comminuted contaminants from the washing fluid so as to retain the comminuted contaminants within the drain chamber while allowing the washing fluid to pass therethrough to the washing fluid circulation system.

Filtration system for a dishwasher, and associated apparatus and method

A screening arrangement for screening washing fluid in a dishwashing appliance is provided. Such a screening arrangement comprises intersecting wall members forming a latticework structure, defining opposing inlet and outlet planes, for receiving the washing fluid therethrough. The wall members have inlet and outlet ends disposed toward the respective inlet and outlet planes. The wall member inlet ends, in cross section, have a non-planar apex portion tapering toward the outlet plane. A circumferential member extends about a periphery of the latticework structure, and at least a portion of the circumferential member is sloped toward the latticework structure so as to direct washing fluid received thereby toward the latticework structure. An associated apparatus is also provided.
