Then, the water guided into the water treatment tank 9 is treated by dissolving the solid medicine introduced into the water treatment tank 9,
The treated water is sent out from the water treatment tank 9 to the water pipe 7b on the downstream side by the water pump 8, and is further pressure-fed to an elevated water tank (not shown) communicating with the water pipe 7b. A three-way motorized valve 11 as a flow path switching means is interposed in the water pipe 7b, and the three-way motorized valve 11 connects the water treatment tank 9 and the water pipe 7b when it is not operating, and when it is operating, it connects the water pipe 7b. This three-way electric valve 11 operates to communicate the processing tank 9 with a recovery pipe 10, which will be described later. Means 12 are electrically connected. The recovery pipe 10 is provided for discharging to the outside the water in which the drug concentration in the water treatment tank 9 has increased due to the stoppage of the water pump 8. As shown in FIG. 2, the flow path switching control means 12 is composed of a sequence circuit, and includes a stop time counting means T1 for counting the operation stop time of the water pump 8, and a three-way electric valve.

becomes conductive, auxiliary relay X1 operates, and X1-1
is open. As a result, the wiring lines 21 and 22 are not electrically connected, and the stop time counting means T1 is stopped. At the same time, contact X1-2 closes. At this time, normally the wiring line 29 becomes conductive and the indicator lamp lights up. Since the 3-way electric valve SV1 is not operating, the treated water flows directly to the water supply line (water treatment tank 9).
and the water pipe 7b). When the water pump 8 stops, contact X1-1 closes and contact X1-2 closes.
is open. At this time, the wiring lines 21 and 22 are brought into conduction again, and the stop time counting means T1 starts counting.

Wiring lines 21, 23, and 24 are electrically connected, and auxiliary relay X2 is activated. As a result, contacts X2-1,
2-2 close respectively. Therefore, when the water pump 8 is operated after the stop time counting means T1 has counted the set time, the wiring line 2
1, 25, and 26 are electrically connected, and the blow operation time setting timer T2 is activated. At the same time, wiring line 2
1, 25, 30, 27 are conductive, auxiliary relay X3
operates, contacts X3-1 and X3-2 close, and contact X3-3 opens. As a result, wiring line 2
8 conducts, the indicator light lights up, 3-way electric valve SV
1 is switched and blowing begins (water treatment tank 9 and recovery pipe 10 communicate). When the blow operation time setting timer T2 finishes counting the set time,
Contacts T2-1 and T2-2 are open and wiring line 2
1, 23, 24 and the wiring line 27 are no longer electrically conductive. As a result, auxiliary relays X2,
3 and the blow operation time setting timer T2 are stopped, and the three-way electric valve SV1 is switched to the water supply line (the water treatment tank 9 and the water pipe 7b communicate with each other).
At the same time, the indicator light lights up.
