Abstract: 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.

Abstract: 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.

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.

Abstract: A method and associated device and appliance for controlling a washing fluid level in a dishwashing appliance are provided. A sump assembly of a dishwashing appliance is filled with washing fluid to a predetermined fluid level determined by a fluid level sensing device directly engaged with the sump assembly. The sump assembly is operably engaged with a tub portion at a lower end thereof. Washing fluid is circulated between the sump assembly and the tub portion. After circulating the washing fluid, an operational fluid level within the sump assembly is determined by the fluid level sensing device. When the operational fluid level differs from the predetermined fluid level by more than a threshold level, one of a washing fluid drain valve and a washing fluid fill valve is actuated to substantially restore the washing fluid to the predetermined fluid level.

Abstract: A covert surveillance system for viewing images from a remote location is provided. The surveillance system provides a mirror, lens and camera arrangement within a small enclosure which allows full 360 degree pan, tilt, zoom, focus and iris control from a remote location. The system receives control commands such as rotate left, zoom out and tilt down via a radio receiver, and controls the camera accordingly. Images viewed by the camera are transmitted to a remote receiver for display on a monitor, or for recording. Continuous camera rotation is achieved by use of a specialized conductive drum which provides continuous electrical contact between camera signals and camera control. In one embodiment, the surveillance system is mounted in place of a photo detector in a street lamp, making the camera virtually undetectable.
