DEVICE FOR THE REGENERATION OF A WATER DECALCIFICATION UNIT IN IRONING APPARATUSES, RELATIVE DECALCIFICATION UNIT AND IRONING APPARATUS COMPRISING SAID UNIT
Device (10) for the regeneration of a water decalcification unit (40), suitable to be integrated in a steam ironing apparatus (30). The decalcification unit comprises at least a tank (11) able to contain the water needed for the production of steam, and a filter (16) containing a resin (29) of the type that can be regenerated by means of a regenerating solution. The regeneration device (10) comprises at least a container element (15) able to contain the regenerating solution and a circuit (50) able to put at least the container element (15) in fluid communication with the filter (16). The circuit (50) comprises at least a first branch (13) to convey at least the regenerating solution from the container element (15) to the filter (16), a second branch (26) to convey at least the regenerating solution from the filter (16) to the container element (15) to allow the recirculation of the solution after the regeneration of the resin (29), and valve means (21, 27, 28) able to put the container element (15) selectively in communication with the filter (16).
