Abstract: A dishwasher includes a tub at least partially defining a treating chamber and a spraying system having a sprayer supplying liquid to the treating chamber. The sprayer may include a liquid passage and at least one spray outlet to emit a spray to wash the dishes and at least one drive outlet to emit a spray to rotate the sprayer. A valve body may adjust the amount of liquid emitted from the at least one drive outlet.

Abstract: A dishwasher includes a tub at least partially defining a treating chamber and a sprayer for spraying liquid to the treating chamber. The sprayer may include a liquid passage provided in the interior of the body, at least one upper outlet extending through the upper surface of the body and in fluid communication with the liquid passage, at least one lower outlet extending through the lower surface of the body and in fluid communication with the liquid passage, and a valve body moveable relative to the body to fluidly couple the at least one upper outlet and the at least one lower outlet to the liquid passage.

Abstract: A foreign object protection system for dishwashers is disclosed. The foreign object protection system prevents large objects from damaging other components of a dishwasher.

Abstract: A dishwasher includes a tub at least partially defining a treating chamber, a rack for holding utensils for treatment within the treating chamber, a first wheel coupled with the tub, a second wheel coupled with the rack, and a track. The track can have first and second channels in a back-to-back relationship for respectively receiving the first and second wheels to slidably mount the rack to the tub.

Abstract: A dishwasher includes a filtration system that can be configured in a chopping or filtration only arrangement. A check valve cover attached to an accumulator is inserted into a main intake of a sump and divides the main intake into a fluid recirculation chamber in communication with a recirculation intake port, and a separate fluid draining chamber in communication with a drain port. When a drain pump is actuated, fluid is pulled from the accumulator through the drain port until pressure within the fluid draining chamber drops below the pressure of the sump and a check valve in the check valve cover is forced open, allowing fluid to be channeled out of the fluid recirculation chamber into the fluid draining chamber. Optionally, a fine filter system can replace the convertible filtration system, whereby the main intake is in fluid communication with both the recirculation intake port and the drain port.

Abstract: A dishwasher includes a tub at least partially defining a treating chamber and a spraying system for supplying liquid to the treating chamber. The spraying system includes a sprayer having a body with an interior, a liquid passage provided in the interior, and an outlet extending through the body and in fluid communication with the liquid passage. A valve body controls fluid to the outlet.

Abstract: A dishwasher includes a tub at least partially defining a treating chamber for receiving utensils for treatment according to the automatic cycle of operation, a rotatable spray arm provided within the treating chamber and defining an interior through which liquid may pass, and hydraulic driving nozzles to rotate the rotatable spray arm in both a a first direction and a second direction, opposite the first direction.

Abstract: A dishwasher includes a tub at least partially defining a treating chamber and a sprayer for spraying liquid to the treating chamber. The sprayer may include a liquid passage and at least one outlet extending from an interior to an exterior of the sprayer and in fluid communication with the liquid passage. A membrane may have at least one opening and may be in fluid communication with the liquid passage to control the flow of liquid through the at least one outlet.

Abstract: An appliance for washing articles such as clothing or utensils, comprises a wash chamber, a wash aid dispensing pump fluidly connected to the wash chamber, multiple wash aid reservoirs and at least one wash aid coupler to fluidly couple the multiple wash aid reservoirs and wash aid dispensing pump. Wherein the wash aid coupler acts as a valve to selectively dispense the wash aid in at least one of the wash aid reservoirs to the wash aid dispensing pump to achieve a more complex cycle of the appliance.

Abstract: A labor grip mechanism on each side of a main frame of a birthing bed, each labor grip mechanism having a post with a free end and a hand grip mounted on the free end. A first mounting construction is provided for slidably supporting each post for simultaneous movement between a first position wherein the hand grip is stowed underneath the patient support and a second position wherein the hand grip is oriented wholly out from underneath the patient support. A second mounting construction is provided for supporting each post for simultaneous rotational movement between the second position wherein the hand grip is also oriented in a plane beneath the plane of the patient support and a third position wherein the hand grip is oriented in a plane above the plane of the patient support. A hand grip positioning device is provided for facilitating the rotational movement only when the posts are in the aforesaid second or third position.

Abstract: A mattress intended for use with a hospital bed such as a maternity bed. The mattress includes a seat section overlies a complementary seat weldment of the litter of the hospital bed. The seat section includes a perineal end located above the perineal edge of the seat weldment. The seat section of the mattress has a perineal pillow wedge assembly that is positioned below a cushion. The perineal pillow wedge assembly includes a load plate that pivots upwardly relative to the perineal edge of the seat section. A mechanism, such as an inflating bladder, is employed to pivot the distribution plate. The pivoting of the distribution plate compresses the perineal end of the cushion. Consequently, a person lying on the mattress is seated against a relatively hard surface. During the delivery process, this hard perineal end surface functions as the surface against which the mother presses to facilitate the delivery.
