WATER SOFTENER HAVING RECYCLING CASE CAPABLE OF RECYCLING ION EXCHANGE RESIN BY INJECTING RECYCLING AGENT INTO RECYCLING CASE

摘要

PURPOSE: To provide a water softener that has a built-in recycling case and is easy to recycle an ion exchange resin in the water softener only by injecting a recycling agent into the recycling case without a separate recycling equipment and a recycling preparation work. CONSTITUTION: The water softener having a column (110) that softens water with an ion exchange resin and a water outlet pipe (140) that discharges soft water is characterized in that it comprises a recycling case (120) that is communicated with the column and the water outlet pipe, an interception pipe (130) that is installed between the column and the recycling case and has a three-way valve (131) and a soft water pipe (150) that is connected to the three-way valve. When using the soft water by opening and closing the three-way valve, the soft water is discharged through the soft water pipe to the water outlet pipe. A recycling agent is injected into the recycling case to recycle the ion exchange resin by supplying a recycled solution through the interception pipe to the water softener.
