Abstract: A filter assembly for filtering a wash fluid to be circulated by a circulation pump in a dishwasher appliance includes a discharge blade defining lateral, transverse and vertical directions. The discharge blade includes a blade hub and a pair of opposing blades, and each of the opposing blades extend outward from the blade hub to a blade tip along the lateral direction. Further, each opposing blade may include a leading edge, a trailing edge, a top surface, and a bottom surface. The trailing edge of at least one opposing blade may be spaced apart from the leading edge along both the transverse and vertical directions, and may define a curve extending between the blade hub and blade tip along the lateral direction. Still further, the top surface of the at least one opposing blade may define a slope between the leading edge and the trailing edge along the transverse direction.

The plurality of first inner threads mesh with the first threaded portion and the plurality of second inner threads mesh with the second threaded portion.

Abstract: In one aspect, a waste disposal for processing waste may generally include a motor, a cutter plate coupled to the motor for rotation therewith and a housing configured to encase the motor and the cutter plate. The housing may include an upper housing portion and a lower housing portion. The upper housing portion may define an inner surface at least partially forming a converging section of the upper housing portion. Additionally, waste disposal may include a plurality of ribs projecting outwardly from the inner surface along the converging section of the upper housing portion.

Abstract: In one aspect, a waste disposal for processing waste may generally include a motor defining a rotational axis, a cutter plate coupled to the motor for rotation therewith and a housing configured to encase the motor and the cutter plate. The housing may include an upper housing portion and a lower housing portion. The upper housing portion may define an inner surface at least partially forming a converging section of the upper housing portion. The upper housing portion may further define an inlet through the converging section. The inlet may be oriented relative to the housing such that water flowing through the inlet is directed into the housing at a non-radial flow angle. In addition, the inner surface may define a curved profile such that a grind chamber of the housing is substantially dome-shaped along the converging section.

Abstract: A dishwasher with a tub at least partially defining a washing chamber, a liquid spraying system, a liquid recirculation system defining a recirculation flow path, and a liquid filtering system. The liquid filtering system includes a rotating filter disposed in the recirculation flow path to filter the liquid.

Abstract: A dishwasher controlled garbage disposal system that momentarily activates the garbage disposal upon activation of the dishwasher to clear the dishwasher's drain route through the garbage disposal. A signal detection and transmission device functionally attached to the dishwasher detects activation of the dishwasher's water pump and sends a signal to a wall mounted control module which activates a pre-operational warning timer. This timer activates for a short time a pre-activation yellow warning light and a fluctuating warning sound. When the warning timer deactivates, a disposal timer activates for a short time a red warning light, a constantly sounding warning sound, and a relay which activates the garbage disposal. A single shot latching relay within the signal detection and transmission device is activated when the dishwasher is initially turned on to prevent the control box from activating more than once during a given wash cycle of the dishwasher.

Abstract: A waste line connector assembly for a food waste disposer includes a tailpipe member having a first inlet connectable to an outlet of a food waste disposer, a second inlet connectable to a waste water outlet of a dishwasher, and an outlet connectable to a waste or drain line. A one-way valve, such as a duck-bill valve, is in fluid communication with the second inlet. A flexible coupler, may be provided to be connected to the outlet, with one or both ends of the coupler being angled and rotatably connected to the outlet and/or the waste line so that the angular position of the waste line is variable relative to the tailpipe member.

Abstract: A food waste disposer has a food conveying section, a motor section and a central grinding section disposed between the food conveying section. The motor section includes a motor having a motor shaft coupled to a rotatable plate of a grinding mechanism in the grinding section. An anti-vibration mount is disposed around an inlet of the food conveying section. The food conveying section includes a housing, which can be a plastic molded housing, having dishwasher inlet having an outer portion extending outwardly from the housing and an inner portion extending into the housing that is removably received in the housing. The inner portion of the dishwasher inlet may be slidably received in the housing with the housing including grooves on opposed sides of an opening that receive tongues on opposed sides of a body of the inner portion of the dishwasher inlet.

Abstract: A dishwasher includes a pump assembly which functions to chop all fluid entrained soil prior to directing fluid to upper and lower wash anms. A flow conduit leading to the upper wash arm is provided with a sampling port which directs a percentage of the fluid flow into a filter chamber having one or more fine mesh filter screens that open into the dishwasher tub basin. The filter chamber is exposed to a collection chamber that leads to a flapper valve and then to a drain port. An overflow tube, which is in fluid communication with the filter chamber, extends upwardly within the dishwasher. When the fine mesh filter becomes clogged, fluid will be forced to flow up the overflow tube and be exposed to another filter. A filter guard is secured to a housing of the recirculation pump over portions of the fine mesh filter.

Abstract: A waste comminuting system and method of use therefore is disclosed, including enhanced safety and water conserving features. The apparatus includes sensor and programming means for enabling coordinated, automated operation of the waste comminuting system based on a schedule of operating conditions, further enabling programmable scheduling of a safety shutter and a water supply common to fluid flow from an automated dishwasher, during concurrent operation of the dishwasher upon actuation by a common controller.

Abstract: A grinding device for a drain pump on a dishwasher appliance includes moving elements that turn integrally with the impeller (5) of the pump (4) and fixed elements joined to the pump hydraulic body (2). The grinding is carried out by the combination of a blade (6), provided with a plurality of vanes, which turns integrally with the impeller (5) and a fixed support (7), provided with a plurality of apertures (7a), the gap between the blade (6) and the support (7) not being dependent on the fitting tolerances of the grinder assembly (1) in the hydraulic body (2) and the end play of the impeller (5).

Abstract: The present invention provides a dishwasher having a wash chamber including a sump. A pump having a rotating element is supported within a pump housing wherein the pump is adapted to draw liquid from the sump through an inlet area and then pump liquid to the wash chamber. A particle chopping assembly is supported in the inlet area upstream of the rotating element, the particle sizing assembly including a particle screen rotatably supporting drive shaft which drivingly supports a chopping blade adjacent the particle screen. The drive shaft has a coupling end which detachably couples to the rotating element. The coupling between the chopping blade and the rotating element is capable of accommodating axial tolerance with regard to the axial position of the rotating element.
