[0002]

2. Description of the Related Art One of the ion exchangers is a water softener, which uses an ion exchange resin to remove hardness components such as calcium ions and magnesium ions contained in raw water. ing. Then, when the ion-exchange resin is replaced by the hardness and becomes saturated, salt water is supplied to regenerate the capacity.

The filling amount of the ion exchange resin is set in accordance with a set processing flow rate or a set water sampling amount (amount of water that can be taken as soft water when the capacity of the ion exchange resin is 100%) for each model. So it differs for each model. And the size of the resin cylinder of each model is set according to the filling amount of the ion exchange resin,
Each model had a dedicated resin cylinder. Therefore, since there are as many types of resin cylinders as the number of models, the management of parts becomes complicated, and the production cost of the resin cylinder has been relatively high for models with a small number of units produced. In addition, in a large-sized water softener, it is difficult to form a resin cylinder by plastic molding, and the resin cylinder is manufactured by can-making from a steel plate, which causes an increase in the number of processing steps and an increase in manufacturing cost.
