Self-optimizing detergent controller for controlling variable additive concentration level in a warewashing machine |
摘要 |
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.
