Perfected hydraulic circuit for optimisation of decalcification in particular for domestic dishwasers and relative control method

摘要

In a domestic dishwasher, a method of control of a perfected hydraulic decalcification circuit comprising a decalcifier (1) formed by a tank (3) for the ion exchange resins and a tank (5) for the resins regeneration salt, a valve (10) for feeding into the resins tank (3) hard mains water intended for washing the dishes and a pair of upper (14u) and lower (14d) filters which define an area of the resins tank for containing the resins, wherein the feed valve (10) of said hydraulic decalcification circuit is made to operate with a flow rate between 2 litres/minute and 2.5 litres/minute.
