PROBLEM TO BE SOLVED: To provide a sodium chloride regenerating vessel convenient for regenerating an ion exchange resin by directly connecting a double tube type built-in vessel, in which sodium chloride is housed to a water softener and introducing sodium chloride while automatically dissolving with the stream of water into the water softener housing the ion exchange resin only by switching a valve in the case of regenerating by passing a sodium chloride solution through in the degraded ion exchange resin in the water softener with the ion exchange resin. SOLUTION: The vessel with sodium chloride is directly connected between a city water faucet and the water softener and the vessel has a switching valve 13 and a double tube composed of an outside pipe 12 having fine pore at the lowermost part and an inside pipe 12-2 having opened both end. When city water flows in the inside part of the double tube with the switching valve switched, the sodium chloride in the vessel with sodium chloride is dissolved at the fine pore part of the lowermost part of the outside pipe 2 to turn to a salt water and introduced into the water softener to regenerate the degraded ion exchange resin. |
