In one aspect of the present invention, a combination dishwashing machine and sink that utilizes a first use solution includes a dishwashing machine, a sump, a pump, a sink, a first fluid passageway, and a controller. The sump is in fluid communication with the dishwashing machine and is configured and arranged to contain the first use solution utilized in the dishwashing machine. The pump is in fluid communication with the sump, and the first fluid passageway interconnects the pump and the sink. The controller is operatively connected to the pump and is programmed to signal the pump to direct the first use solution from the sump, through the first fluid passageway, and into the sink. The controller automates the filling of the sink with the first use solution from the sump.

A dispenser () uses first and second flow controls (). The flow controls maintain first and second flow ranges independent of diluent pressure within a pressure range, wherein the use solution's concentration is maintained over the pressure range. A third flow control () may also be utilized in a third diluent passageway for maintaining a third flow range independent of the diluent pressure within the pressure range. A bypass valve assembly () is operatively connected to the third incoming diluent passageway. The bypass valve has a temperature control valve. The temperature control valve having a bypass passageway, wherein additional diluent is added to the use solution, thereby controlling the use solution's concentration.

Solid product dispenser

Method and apparatus to control dispensing rate of a solid product with changing temperature

A product dispenser, solid product, and a dispensing system containing the product dispenser and solid product are disclosed. Methods for using the product dispenser, solid product, and dispensing system are also disclosed.

Product dispenser

A dispensing system for dispensing chemical products to a plurality of utilization points utilizes a multi-port valve to selectively deliver use dilutions from a mixing apparatus to selected utilization points. The multi-port valve utilizes a position sensor to provide positive proof-of-delivery by detecting the angular position of a rotor relative to a stator in the valve. The position sensor includes opposing annular arrangements of detectable elements and proximity detectors which rotate relative to one another about a common axis in response to rotation of the rotor such that detectable elements are oriented in proximity to a unique combination of proximity detectors at each of a plurality of predetermined angular positions. As a result, unique codes are output from the proximity detectors to positively identify positioning of the rotor at the predetermined angular positions.

Disclosed is a warewashing assembly comprising a batch-loading warewashing machine and a movable tray or cart capable of holding a rack in a position that departs form the horizontal outside of the warewashing machine for convenient operations; said tray or cart comprising a flat tray of a size complementary to said rack, wherein the flat tray comprises side and rear fences capable of holding the ware rack against horizontal motion and wherein the tray is attached to a support structure in such a way that it is supported at the desired angle .alpha. and can be inserted into the machine when quiescent; wherein the support structure is of a height approximately equal to that of the warewashing machine and comprises means to move horizontally in relation to the warewashing machine.

Removable warewashing apparatus

This invention relates to an apparatus and method for diluting a chemical concentrate. More particularly, dilution control is achieved by monitoring two flow meters, comparing the flow rate information, and adjusting the diluent flow to achieve a predetermined dilution of the chemical concentrate. An air push is preferably used to deliver the chemicals to the utilization points. Also a controller is used to prioritize requests from the utilization points in a hierarchal fashion.

Liquid chemical dilution and dosing system

An apparatus and method for programming a controller to vary the concentration set-point of an additive as a function of time. The present invention insures that the additive is injected to the machine at proper times to allow for optimum efficiency and lowest cost. To vary the set-point according to the input parameters, the invention combines the features of a data entry device, a microprocessor, a clock, a controller, and sensors into one unit. The user may enter a time setting and set point into the controller, along with control parameters which allow the machine to control the additive injection based on different user-defined scenarios. The microprocessor then reads the settings and outputs an appropriate set-point value from the microprocessor to the controller. Thus, the user can manually or automatically change the response function if and when conditions change.

An apparatus and method for programming a detergent controller to vary the detergent concentration set-point according to the time of day and to achieve detergent concentration levels quickly without incurring overshoot. Thus, the present invention insures that the warewashing machine is operated at optimum efficiency and cost. To vary the set-point according to the time of day, the invention combines the features of a microprocessor, a clock and a controller into one unit. The user enters the time setting and set point into the controller. The microprocessor then compares the real-time clock signal with the user time settings and outputs an appropriate set-point value from the microprocessor to the controller. To achieve detergent concentration levels quickly without incurring overshoot, the controller senses the detergent concentration and dispenses the proper detergent level to the warewashing machine according to a predetermined detergent feed time based on the previous response time and the programmed set-point. Thus, the controller can change the response function if and when conditions change.

Disclosed is a dispenser 10 for a solid chemical 13 and a method of dispensing the chemical 13. Water enters via an inlet line 22 and is sprayed from a spray nozzle 21, so that the solid chemical 13 is dispensed in the form of an aqueous chemical solution via outlet line 17. The solution's concentration is adjustable by varying the distance between the spray nozzle 21 and the exposed dissolving surface of the chemical 13. The spray nozzle's position is adjusted by means of a screw jack 68, a push-pull cable 93, a solenoid 100, or a lever 117.
