補水工程に移る。Next, a salt water regenerating step for regenerating the ion exchange resin will be described. In the salt water regeneration step, the raw water valve is closed and the regeneration valve is opened, so that saturated salt water in the salt water tank flows down into the regeneration line through the salt water line. On the other hand, the raw water in the raw water tank flows down into the regeneration line, and the saturated salt water and raw water are mixed at a connection point with the salt water line to become salt water having a predetermined concentration (about 10%), and the lower part of the resin cylinder Flows upward as a flow to regenerate the ion exchange resin. The salt water after regeneration is discharged through the soft water line. Then, when the whole amount of the saturated salt water in the salt water tank is made to flow down and the salt water regenerating step is completed, the process goes to the next water washing step. In this water washing step, the raw water remaining in the raw water tank flows down the regeneration line and flows upward from the lower part of the resin cylinder, and the salt remaining in the ion exchange resin is pushed out and washed. The raw water after washing is discharged through the soft water line. As a result, when all the raw water in the raw water tank flows down, the water washing process is completed, the regeneration valve is closed and the raw water valve is opened to move to the water passage process and the water supply process.

ることができる。As described above, in the water softener of the present invention, the raw water tank and the salt water tank are arranged above the resin cylinder to use the gravity regeneration system, and the water passing step, the salt water regeneration step, and the water washing step are all performed. Since it is an upward flow, compared to the conventional water softener, it does not require an expensive control valve, and a commercially available valve can be used to provide a compact, low-priced water softener. Further, since the conventional backwashing step at the time of regenerating the ion exchange resin is not required and the water replenishing step is performed at the same time as the water passing step, the regeneration cycle of the ion exchange resin can be simplified.

を提供することができる。As described above, according to the present invention, the raw water tank and the salt water tank are disposed above the resin cylinder, the raw water line is connected to the lower portion of the resin cylinder, and the lower portion of the raw water tank and the resin tank are connected to each other. The lower part of the cylinder is connected by a regeneration line, the salt water line connected to the lower part of the salt water tank is connected to this regeneration line, and salt water in which raw water and saturated salt water are mixed flows in as an upward flow from the lower part of the resin cylinder. Since I did so, I operated the conventional control valve and (1)
The ion exchange resin was regenerated by four cycles of backwashing, (2) salt water regeneration, (3) water washing, and (4) replenishment water.
It is possible to provide a compact and low-priced water softener by simplifying the three cycles of (1) salt water regeneration, (2) water washing, and (3) water replenishment, and without using an expensive control valve. .
