Abstract: During the rinse cycle of a re-circulating dishwashing machine (132), water is simultaneously diverted into a dispenser (100) as water is delivered to the rinse arms (133) of the dishwashing machine (132). The cavity (118) of the dispenser (100) contains a solid detergent block (125) and is flooded with water during the rinse cycle. The water contacts the detergent (125) during the rinse cycle to create a use solution, and the use solution exits the dispenser (100) and flows into a wash water storage tank (135) of the dishwashing machine (132). During the wash cycle of the dishwashing machine (132), the wash water containing the use solution from the dispenser (100) is pumped into the wash arms (134). The wash water becomes diluted during the subsequent rinse cycle, however, the water diverted into the dispenser (100) during the rinse cycle replenishes the detergent (125) concentration in the wash water for use in the subsequent wash cycle.

Abstract translation: 在再循环洗碗机（132）的漂洗循环期间，当水被输送到洗碗机（132）的冲洗臂（133）时，水同时被转移到分配器（100）中。 分配器（100）的空腔（118）含有固体洗涤剂块（125），并在漂洗循环期间被水充满。 在漂洗循环期间，水与洗涤剂（125）接触以产生使用溶液，并且使用溶液离开分配器（100）并流入洗碗机（132）的洗涤水储存箱（135）。 在洗碗机（132）的洗涤循环期间，将含有来自分配器（100）的使用溶液的洗涤水泵入洗涤臂（134）。 洗涤水在随后的漂洗循环期间被稀释，然而，在漂洗循环期间转移到分配器（100）中的水补充洗涤水中的洗涤剂（125）浓度，以用于随后的洗涤循环。

Abstract: A UV absorption spectrometer includes a housing, a controller, and a sensor unit including an ultraviolet light source, an analytical area in an analytical cell or in running water or gaseous medium, and an UV wavelength separator including a UV detector. An ultraviolet light in a wavelength range of 200-320 nm emits from the light source through the analytical area to the wavelength separator, and the controller transforms output signals from the UV detector into absorbance values or optical densities for two or more wavelengths in the wavelength range, calculates differences of said absorbance values or optical densities, determines a concentration of a chemical in the solution with calibration constants found for a known concentration of the chemical and said differences of said absorbance values or optical densities.
