Abstract:
1. An electrochemical cell device arranged in an automatic cleaning appliance used in the cleaning of objects comprising: a first metallic plate, a last metallic plate and a plurality of intermediate metallic plates, each of said plates having two essentially parallel sides with a large surface area in comparison with a peripheral side connecting said parallel sides, a connection between a positive electrode of a source of direct electrical current and said first plate and a connection between a negative electrode of said source of direct electrical current and said last plate, a connection to a supply of water for use in the cleaning appliance, and including a conduit leading from the supply of water used in the appliance to the electrical components providing the rectified current to cool the components with water used in the appliance, and a conduit leading from the electrical components to the cavity in the appliance to be used in the cleaning of the objects, an inlet to allow the introduction of a fluid containing a chemical composition to be decomposed by said cell device during a period of decomposition and an outlet to allow the dispensing of resultants of the decomposition of said chemical composition into the cavity of the appliance, wherein the electrochemical device generates a chemical composition and a sensing system provided within a cavity of the automatic cleaning appliance is configured to measure properties of wash liquor in the cavity of the automatic cleaning appliance and control dispensing of the chemical composition into the automatic cleaning appliance based on the measurement.
