摘要： A dishwasher pump and automatic purge system which includes a wash impeller supported for rotation within a pump chamber wherein the pump chamber has a main outlet and a sample outlet port. Wash liquid pumped out through the main outlet is recirculated throughout the dishwasher interior wash chamber. A soil collector receives wash liquid through the sample outlet port. The soil collector includes a filter screen for returning filtered wash liquid back into the sump such that soils are retained in the soil collector. Pressure within the soil collector is sensed by a pressure sensor. The soil collector is purged by a drain pump when the pressure within the soil accumulator exceeds a predetermined limit level such that soils are cleared from the collector and the filter screen. When the pressure within the soil accumulator is reduced to below the predetermined limit level, the drain pump is deenergized. A control valve is provided for preventing fluid flow from the dishwasher sump to the drain pump during the purge operation while the wash pump is operating. The control valve is operated in response to fluid pressure created by the wash impeller.

摘要： A dishwasher is provided having a wash pump and soil collection system. The wash pump may be a volute type pump having a horizontal axis and includes a casing surrounding a wash impeller. The casing has a main outlet and a secondary outlet. The wash impeller draws wash liquid from the dishwasher sump region and pumps the wash liquid through the main outlet and the secondary outlet. The wash liquid pumped through the main outlet is provided to a wash arm device such that wash liquid is recirculated throughout the dishwasher interior wash chamber. The wash liquid pumped through the secondary outlet is directed to flow into a soil collector. The soil collector includes a soil separation channel which receives the flow from the secondary outlet and includes at least one filter screen panel for returning filtered wash liquid back into the sump such that soils are retained in the soil separation channel and accumulate within a soil accumulator region. A pressure sensor may be provided for sensing the pressure within the soil accumulator. A drain pump is provided having an inlet fluidly connected to the soil separation channel. When the pressure within the soil collector exceeds a predetermined limit level, the drain pump is energized such that soils are cleared or purged from the soil collector. Alternatively, a second outlet may be provided in the soil collector through which wash liquid flows back into the wash chamber when the filter screen is clogged with soils.

摘要： A dishwasher pump and automatic purge system for a dishwasher having a recirculation pump, a drain pump and a wash chamber having a sump. The recirculation pump includes a main outlet and a secondary outlet wherein wash liquid pumped out through the main outlet is recirculated throughout the dishwasher interior wash chamber during a wash phase. The sump includes a soil collector which receives wash liquid from the secondary outlet. The soil collector includes a filter screen for returning filtered wash liquid back into the sump such that soils are retained in the soil collector. During a first wash phase while the recirculation pump is recirculating wash liquid throughout the wash chamber, the drain pump is energized on and off to drain soils from the soil collector. More specifically, the drain pump is energized on and off during the wash phase in response to the pressure within the soil collector which is sensed by a pressure sensor.

摘要： A dishwasher having a fluid recirculation system which operates in a wash mode for spraying liquid onto objects supported on dishwasher upper and lower racks. The dishwasher includes a pump having a pump impeller disposed within a pump chamber for supplying wash liquid to first and second spray devices, associated with the lower rack and upper racks, respectively. The pump impeller draws wash liquid into the pump chamber and imparts a rotary motion to the wash liquid disposed in the pump chamber. A rotatable diffuser or flow director having a plurality of vanes extending into the pump chamber selectively directs the rotating wash liquid toward the spray devices and thereby controls wash liquid recirculation within the dishwasher responsive to the rotational motion of the wash liquid in the pump chamber.

摘要： A thermal input system is provided for a dishwasher having an interior wash chamber receiving soiled dishes and wash liquid. A heater is disposed in a sump region of the wash chamber along with a wash pump which operates to recirculate wash liquid through out the wash chamber. A soil collection chamber receives a portion of recirculating wash liquid from the wash pump wherein soils entrained in the wash liquid are captured within the soil collection chamber. A pressure sensor senses fluid pressure within the soil collection chamber. Control means are provided for energizing the heater during a thermal hold period in response to the pressure within the soil collector exceeding a predetermined limit pressure. In particular, the control means operates to sequence the dishwasher through a predetermined period of operation but bypasses the thermal hold cycle when the pressure within the soil collector does not exceed the predetermined limit pressure.

摘要： A soil separator for a dishwasher includes soil accumulator channels open to the dishwasher chamber but covered by a filter screen having a fine filter region and a coarse filter region. Accumulator sumps are arranged below the accumulator channels. The shallow accumulator channels allow water to flush soil from an inside of the screen to the accumulator sumps. The channel below the fine filter region is flow connected through a pressure control valve or standpipe to the channel below the coarse filter region. If the fine filter region becomes clogged, the soil laden water can be passed into the coarse filter region for coarse screening.

摘要： A dishwasher construction having a molded one piece tub with integrally molded reinforcing ribs on an outside surface of the tub, the reinforcing ribs being hollow members formed by gas injection molding. At least one of the reinforcing ribs can be fashioned as a hollow conduit for transferring water from a bottom mounted pump to a top mounted wash arm of the dishwasher, or from a drain pump to a drain outlet. By using hollow reinforcing members molded integrally with the tub, an external upper wash arm conduit is avoided which can have external leakage, and an internal upper wash arm conduit is avoided which tends to restrict the working space within the dishwasher and can trap food and be otherwise functional and unappealing to the consumer.

摘要： A soil separator for a dishwasher includes a centrifugal soil collection wall surrounded by a spill over guide channel, surrounded by a shallow annular accumulator channel. The soil accumulator channel is open to the dishwasher chamber but covered by a filter screen. An accumulator sump is arranged below the accumulator channel. The accumulator channel is partially formed by a plate or grating provided with spaced radial slots to allow soil to drop into the accumulator sump as it progresses around the accumulator channel. The shallow accumulator channel allows water to flush soil from an inside of the screen to the accumulator sump.

摘要： A soil separator and water distributor for a dishwasher having an annular screen facing into the dish compartment for screening wash water, and a rotating flush arm above the annular screen for flushing soil from an underside of the screen, and a separate wash water arm above the flush arm for spraying the dishes. The wash water arm can thus be flow separated from the flush water arm. Thus, the wash water arm can be operated intermittently while the flush water arm can be operated continuously.
