A dishwashing apparatus may include a sump. The sump may include a sump pan configured to couple with a wash chamber of the dishwashing apparatus. The sump may include a sump well coupled to the sump pan and configured to collect the liquid from the sump pan. The sump well may include a well inlet in communication with the sump pan. The sump pan may convey the liquid to the well inlet. A recirculation port extending through a first wall of the sump well. A drain port may extend through a second wall of the sump well. The second wall defines a bottom of the sump well. The dishwashing apparatus may include a controller. The controller may monitor electrical characteristics of a pump. The controller may provide a notification if fluid is not flowing through the pump.

A water reuse system and controller for controlling water levels, temperature, and quality in the rinse water reuse system and methods of using the same, in order to optimize water usage. More particularly, the application pertains to a controller and methods of using the controller to regulate water levels and water quality in a water reuse system. As part of detailing the controller and methods of using the same, an apparatus for a water reuse system is also provided.

Fluid delivery devices (), systems (), and methods are disclosed. A fluid delivery device () includes a body (), a solution flow path (), and a flush flow path (). The solution flow path and the flush flow path are defined at the body. The solution flow path extends from a solution inlet (), defined at the body, to a solution outlet (), also defined at the body. The solution flow path includes a cross channel (), an inlet channel (), and an outlet channel (). The inlet channel extends from the solution inlet to the cross channel. The outlet channel extends from the cross channel to the solution outlet. The flush flow path extends from a flush inlet (), defined at the body, to a flush outlet (), also defined at the body. The solution outlet fluidly connects the solution flow path to the flush flow path.

Controller for a rinse water reuse system and methods of use

A dispenser includes a dock configured to be fixed in place at a use device and a solid product holder configured to be removably secured to the dock. The dock has a first portion including a fixation element that is configured to fix the dock in place at the use device and a second portion including a receiving structure. The solid product holder includes a retaining structure, a base, and a support structure. The retaining structure is configured to removably secure the solid product holder to the receiving structure at the second portion of the dock. The base defines a plurality of apertures that form an open area at which the liquid is received at the solid product holder. The support structure extends from the base and defines an internal volume for holding the solid product at the solid product holder.

A material wetting system for wetting a powder material includes a liquid supply system, a material mixing unit, a material supply system, and a shroud assembly. The liquid supply system includes a supply line. The material mixing unit is in fluid communication with the supply line and includes a central cavity having an open upper end configured to receive a supply of powder material. The material mixing unit is configured to receive liquid from the supply line and is operatively connected to a reduced pressure source to draw air into the central cavity. The material supply system includes an orifice and is configured to feed powder material through the orifice, with the orifice disposed above the central cavity of the material mixing unit. The shroud assembly is disposed about the open upper end of the central cavity of the material mixing unit and the orifice of the material supply system.

A hopper system for powder material includes a hopper and a cover. The hopper has hopper sidewalls that extend downward from an upper end of the hopper with at least one of the hopper sidewalls being sloped along a portion thereof. A hopper axis extends vertically between at least some of the hopper sidewalls. The cover is disposed at the upper end of the hopper and includes an opening configured for the powder material to flow therethrough and into the hopper. The opening defines a vertical material loading axis that is offset relative to the hopper axis. A diverter member may be provided that is positioned along the material loading axis and configured to divert the powder material entering through the opening. A powder material feed system may be disposed adjacent the lower end of the hopper to feed the powder material from the hopper.

A fluid-driven chemical product dispensing system dispenses fluid chemical product concentrates. The dispensing system includes a fluid drive unit powered by flow of a fluid, such as a diluent, and a pump which delivers the fluid chemical product concentrate from a supply to a destination. Upon exit from the fluid drive unit, the diluent is also delivered to the destination, where it mixes with the dispensed fluid chemical product concentrate to form a use solution. The dilution ratio of the volume of fluid chemical product concentrate dispensed per unit time versus the volume of diluent exiting the drive unit per unit time is constant over a defined range of diluent flow rates.

A material supply assembly includes a valve assembly having an outer valve member and an inner valve member rotatable relative to the outer valve member. A base assembly includes an base structure and an actuator. An engagement structure is operative between the outer valve member and the actuator to prevent relative movement between the outer valve member and the actuator. A locking structure is operative between the inner valve member and the base structure to prevent relative movement between the inner valve member and the base structure. Movement of the actuator relative to the base structure moves the outer valve member relative to the inner valve member to operate the valve assembly.
