In the water passing step of opening the soft water, the solenoid valves 13 and 16 are opened, the solenoid valves 18, 21 and 25 are closed, and the raw water in the raw water tank 4 is passed through the raw water line 7. It is supplied from the raw water inlet portion 6 of the resin cylinder 1. That is, by the signal of the flow sensor 12 of the raw water line 7,
A controller (not shown) drives the water supply pump 8 to pass the raw water as an upward flow from the lower part of the resin cylinder 1, and in this water passing process, the hard water is softened by the action of the ion exchange resin 3, Soft water is supplied from a soft water outlet 14 provided at the top of the cylinder 1 through a soft water line 15. In the water passing process, the ion exchange resin 3 floats by the upward flow of the raw water and settles when the supply of the raw water is stopped. Therefore, since the ion exchange resin 3 is loosened by repeating the supply and stop of the raw water, the conventional backwashing process becomes unnecessary.

ライン１７を介して供給し断水を回避する。Next, a salt water regenerating step for regenerating the ion exchange resin 3 will be described. In the salt water regeneration process,
The solenoid valves 13 and 16 are closed and the solenoid valves 18 and 21,
By opening the valve 25, the saturated salt water in the salt water tank 5 flows down through the salt water flow line 19. On the other hand, the raw water in the raw water tank 4 flows down through the raw water flow-down line 22, and the saturated salt water and the raw water are mixed at the soft water outlet portion 14 to become salt water having a predetermined concentration (about 10%). The ion-exchange resin 3 is regenerated by flowing down from above. The salt water after regeneration is discharged out of the system through the drain line 24. Then, when a predetermined amount of salt water is caused to flow down and the regeneration of the ion exchange resin 3 is completed, the process proceeds to the next water washing step. The controller uses the solenoid valve 2 of the salt water flow line 19
1 is closed, and the salt remaining in the ion exchange resin 3 is extruded with the raw water from the raw water downflow line 22 and washed with water.
The raw water after washing is discharged out of the system through the drain line 24. Then, a predetermined amount of raw water is made to flow down to extrude the salt content to complete the regeneration. After completion, each solenoid valve is returned to the water passing state. Incidentally, during the salt water regeneration step,
When the faucet is opened and the signal from the flow rate sensor 12 is transmitted, the controller drives the water supply pump 8 to supply the raw water through the bypass line 17 to avoid water interruption.

Move to the next rehydration process. That is, raw water flows from the raw water tank 4 into the salt water tank 5 through the connecting pipe 28 (replenishing water) to generate and store saturated salt water for the next regeneration. Further, due to the action of the water level control device 26 of the raw water tank 4, the raw water flows from the raw water supply line 27 to a predetermined water level in the raw water tank 4. As described above, the method for controlling the water softener may be four cycles of (1) water passing step, (2) salt water regeneration, (3) water washing step, and (4) rehydration step, and the conventional (1)
Water flow step, (2) backwash step, (3) salt water regeneration step,

ので、従来の逆洗工程は不用となる。Next, the operation of the water softener having the above construction will be described. First, when the faucet (not shown) of the soft water line 15 is opened and the soft water is allowed to flow, the solenoid valves 13 and 16 are opened, the solenoid valves 18, 21 and 25 are closed, and the inside of the raw water tank 4 is closed. The raw water is supplied from the water pipe 32 in the resin cylinder 1 through the raw water line 7. That is, a controller (not shown) is generated by the signal from the flow sensor 12 of the raw water line 7.
Drives the water supply pump 8 to pass the raw water as an upward flow through the water pipe 32 in the resin tube 1, and in this water passing process, the hard water is softened by the action of the ion exchange resin 3, Soft water is supplied through a soft water line 15 provided at the upper part of 1. In the water passing process, the ion exchange resin 3 floats due to the upward flow of the raw water and sinks when the supply of the raw water is stopped. Therefore, since the ion exchange resin 3 is loosened by repeating the supply and stop of the raw water, the conventional backwashing process becomes unnecessary.

And the solenoid valves 18, 21 and 25 are opened, the saturated salt water in the salt water tank 5 flows down through the salt water flow line 19. On the other hand, the raw water in the raw water tank 4 flows down through the raw water flow-down line 22, and below the salt water flow-down line 19, the saturated salt water and raw water are mixed to become salt water having a predetermined concentration (about 10%). The ion exchange resin 3 is regenerated by flowing down from the upper part of the cylinder 1. The salt water after regeneration is discharged out of the system through the drain line 24.
Then, when a predetermined amount of salt water is made to flow down and the regeneration of the ion exchange resin 3 is completed, the controller closes the electromagnetic valve 21 of the salt water flow-down line 19 so that the raw water from the raw water flow-down line 22 causes the ions to flow. The salt remaining in the exchange resin 3 is washed with water, and the washed raw water is discharged to the outside of the system through the drain line 24. Then, a predetermined amount of raw water is made to flow down to wash salt to complete the regeneration. After the completion, each solenoid valve is returned to the state where the soft water is passed. In addition, during the playback,
When the faucet is opened and there is a water supply request, raw water is supplied through the bypass line 17 to avoid water interruption.

クルより簡略化することができる。When the regeneration is completed and a soft water flow state is reached,
Raw water flows from the raw water tank 4 into the salt water tank 5 through the connecting pipe 28 (replenishing water) to generate and store saturated salt water for the next regeneration. Further, due to the action of the water level control device 26 of the raw water tank 4, the raw water flows from the raw water supply line 27 to a predetermined water level in the raw water tank 4. As described above, the ion exchange resin can be regenerated by (1) salt water regeneration, (2)
Three cycles of washing with water and (3) replenishing water are required, which can be simplified from the conventional four cycles of (1) backwashing, (2) salt water regeneration, (3) washing with water, and (4) replenishing water.
