  • Patent number: 10321797
    Abstract: The present invention provides a pump plate (60) for conditioning the flow of a fluid before the fluid enters an inlet (51) of a circulation pump (50) of a dishwasher. The pump plate (60) may have a plate portion with a number of holes (62) dispersed across its surface such that fluid may flow through the holes (62). The pump plate (60) may also include one or more upper guide vanes (63) extending outwardly from the plate portion and configured to reduce the turbulence in the fluid flow. A dishwasher (10) including a pump plate (60) and a method for manufacturing such a dishwasher are also provided. A dishwasher (10) that includes a pump plate (60) to condition the fluid flow within the dishwasher may be configured to function efficiently while requiring less water to complete a rinse or wash cycle than a dishwasher that does not include a pump plate.

  • Patent number: 9301670
    Abstract: 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.

  • Patent number: 9204780
    Abstract: 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.

  • Publication number: 20130025637
    Abstract: According to exemplary embodiments, a dishwasher or other washing appliance includes a siphon break apparatus configured to substantially prevent a siphon effect in a fluid conduit configured to drain fluid from the dishwasher or other washing appliance. The siphon break apparatus may include a body portion that may be divided by a filter into a filter chamber and a flow chamber. The filter chamber may extend perpendicularly from the flow chamber. An aperture may be defined in the filter chamber and sealed shut by a domed closure of a normally-closed umbrella valve. The domed closure may unseal from the aperture and thereby allow air to enter the filter chamber, travel through the filter and into the flow chamber so as to relieve a low pressure region and substantially prevent a siphon effect in the fluid conduit. A related method is also provided.
