PROBLEM TO BE SOLVED: To reduce production cost, to enable to install a device even in a small space in an apartment house, etc., and to enable to promptly exchange a water softening part at the time of exchanging it by putting an ion exchange resin material into a container capable of attaching to a main body and detaching and forming the water softening part. SOLUTION: A water softening device 10 is provided with an inflow port 12 for allowing water to flow in, the water softening part 14 put an ion exchange resin part in it and exchanging hard ions of inflow water to soft ions and an outflow port 16 for flowing out softened water. The water softening part 14 is composed by putting the ion exchange resin part into the container 2 enabling to attach to the main body 18 and detach. Thus, the water softening part 14 on one side is removed and then is regenerated and again attached or another water softening part 14 is attached and successively exchanged. Hard ions remaining on the ion exchange resin material in the water softening part 14 detached from the main body 18 is washed out and regenerated and can be again attached to the main body 18. |
