Abstract: An integrated recycling system for dishwashing machine includes an impeller positioned within the sump of the dishwashing machine, an impeller housing enclosing the impeller within the sump, and a motor for rotating the impeller within the impeller housing whereby a flow of water is achieved from the sump to one or more spray arm assemblies of the dishwashing machine, the impeller housing being formed from a strip of sheet metal that is cut to the proper length and wound around the impeller, defining an arcuate-shaped peripheral wall portion of the impeller housing that is open on opposing sides, one side being closed by a plate member and the other side being closed by a wall of the sump on which the impeller housing is mounted.

Abstract: A mixing apparatus having a bowl lift arrangement which includes a yoke which is attachable to the mixing bowl and which includes only one guide rod for supporting the yoke, the guide rod being located in the forward portion of a support column which supports the drive motor housing above the base of the mixing unit, and the guide rod being centered to extend vertically along and an axis co-planar with the axis of the bowl. The bowl lift arrangement further includes a screw shaft extending parallel to and behind the guide rod and which has one end received in a threaded aperture provided in the rearward end of the base portion of the yoke, the other end of the screw shaft being linked to a handle, turning of which causes rotation of the screw shaft, with the yoke riding up or down on the screw shaft as it is rotated, carrying the bowl up or down.

Abstract: A dishwashing machine includes a plurality of sections through which a soiled article to be washed is transported. A dishwashing machine includes a detergent pre-wash section, a detergent-wash section, a chemical power rinse and final clear water rinse section.

Abstract: A protector device for preventing the passage of elongated members such as silverware, and the like, into a drain outlet, the device having a baffle member mounted within an annular member for the passage of liquid therebetween and with the annular member adapted to be disposed around the drain outlet in axially outwardly spaced relation thereto for the passage of liquid radially inwardly past the annular member into the drain outlet.

Abstract: A drain plug of the standpipe type embodying an elongated tubular member for affording drainage when the liquid level in a compartment is at the top of the standpipe, and a resilient, annular valve member mounted on the lower end portion of the standpipe for sealingly engaging a valve seat in a drain opening for preventing flow of said liquid into said drain opening around said standpipe, the valve member having an upper and lower flanged construction that is effective to guard against leakage around and damage to the drain plug if the drain plug is improperly aligned or excessive closing pressures are applied thereto.

Abstract: A trough, which receives mixed water and waste, has first and second openings in the bottom thereof. Oscillating grid means overlies the first opening, and is associated with stationary wiper means. The grid means allows the water to flow therepast into the first opening, and in conjunction with the wiper means directs the waste into the second opening.
