    摘要： A conductivity measurement system provides one or more DC pulses to first and second electrodes submerged in an aqueous solution such as, for instance, the wash water of an industrial dishwasher. The voltage at the first electrode is measured at first and second predetermined times after initiation of DC pulse(s). Linear regression of the first and second measured voltages is used to calculate the voltage at the first electrode at the beginning of the DC pulse(s), i.e., at time t=0. The resulting voltage at time t=0 is then used to calculate the conductivity of the solution, thereby compensating for the effects of polarization. Further, the difference between the respective first and second measured voltages is compared to a predetermined threshold value to determine whether the electrodes are so contaminated that polarization compensation is no longer feasible, thereby signaling that the electrodes should be cleaned or replaced.

    摘要： A liquid chemical dispensing system for dispensing a plurality of liquid chemicals into a dishwasher includes at least a detergent pump and a rinse agent pump, a first switch indicating whether the dishwasher is a door type or a conveyor type dishwasher, a second switch indicating whether said controller is in training mode or in run mode, a non-volatile memory and a data processor. The liquid chemical dispensing system is powered on whenever the dishwasher is spraying rinse water. In the training mode, the data processor enables a user to set values for a rinse run time parameter, a detergent run time parameter, and a rinse delay time, and stores those parameters in the non-volatile memory. In the run mode for door type dishwashers, each time the system is powered on the data processor runs the detergent pump a length of time corresponding to the stored detergent run time parameter, delays running the rinse pump, from the time of each power on, by an amount of time corresponding to the stored rinse delay time parameter, and then runs the rinse pump a length of time corresponding to the stored rinse run time parameter. In the run mode for conveyor type dishwashers, the data processor runs the rinse pump each time the system is powered on, and runs the detergent pump for N seconds for each M seconds that the rinse pump is run, where N is the detergent run time parameter and M is a predefined value.

    摘要： An apparatus for dispensing liquid chemicals into a laundry machine is described. An operator interface with a small number of programming/execution buttons is provided. The programming/execution buttons are pressed to define a liquid dispensing program which is stored as a compact set of instructions which can be executed with minimal computing power. Each step of the liquid dispensing program is defined by either delay information or chemical volume dispensing information, and a synchronization flag. When enabled, the synchronization flag in a program step causes the apparatus to wait for a synchronization signal before executing the program step. Synchronization signals are produced by a sensor that identifies water flows either into or from the laundry machine. A microcontroller, in conjunction with a program execution module, executes the liquid dispensing program by waiting through time delay periods dictated by the cycle delay information, generating pump activation commands based upon the chemical volume dispensing information, and waiting for a synchronization signal for each program step that includes a synchronization flag. A pump interface receives the pump activation commands and forces a defined volume of liquid chemicals from a chemical container into a receptacle positioned on the laundry machine.

    摘要： A dispenser cap for a non-liquid chemical delivery system is disclosed. The dispenser cap is attached to the base of a chemical container holding a non-liquid chemical. The dispenser cap is also coupled to a discharge conduit which includes a nozzle positioned within it. The nozzle may produce a direct vertical spray and a circumferential spray into the dispenser cap. The dispenser cap disclosed includes a distributor for intercepting the direct vertical spray of water into the dispenser cap. The distributor indirectly conveys the intercepted water into the container. The water conveyed into the container by the distributor produces a stream of chemicals which exits the container through the discharge conduit, without impinging upon the nozzle.

    摘要： The chemical distribution system (100) includes at least a first chamber that is fluidly coupled to a second chamber below it, which is in turn fluidly coupled to a manifold below it. In use, water and a powdered chemical are introduced into the first chamber. Liquid chemicals, however, are injected into the second chamber through multiple chemicals inlets in the second chamber. A pressure sensor fluidly coupled to the first chamber is used to accurately measure dosages of the liquid chemical. Once the accurate dosages have been determined, the powdered and/or liquid chemicals are distributed through one of multiple manifold outlets and along a single line (116(a), 116(b)) to one of multiple washing machines (102(a), 102(b)).

    摘要： Prior to adding detergent or chelant, the conductivity of water in a washing chamber is measured. The maximum concentration of hard water ions that could correspond to the measured conductivity is determined, i.e., it is assumed that all of the conductivity is from calcium and/or magnesium ions in the water even though other ions may in fact be contributing to the measured conductivity. Enough chelating agent is added to the chamber to sequester this maximum concentration of hard water ions and the conductivity is measured again. Using the two conductivity measurements, the actual concentration of hard water ions is determined. A chelant factor based on the actual concentration of hard water ions is then used to determine the amount of chelant to be added for subsequent wash cycles to sequester all of the hard water ions.
