PURPOSE:To prevent idle beat of an electromagnetic pump, to decrease to the utmost the remaining quantity at the time when no-liquid is decided definitely by using effectively a disinfectant solution, and also, to simply constitute the disinfactor. CONSTITUTION:A disinfectant solution LQ in a tank 12 is pumped up by an electromagnetic pump 15 and pressurized and supplied to a nozzle 13. Insertion of hand fingers into a disinfecting room 11 is monitored by a photosensor 21. A control circuit 19 command as injection of a commanded injection time to the electromagnetic pump 15, whenever the hand fingers are inserted. The liquid surface of the tank 12 is monitored by a liquid surface level sensor 20. When the sensor 20 detects a reference level, the number of times of injection which can be supplied by the consumption to the lower limit level is calculated by the control circuit 19 in accordance with the injection time per once, commanded at that time point. There-after, the control circuit 19 permits the injection of only the calculated number of times of injection to the electromagnetic pump 15. It is also allowable that the permission of this injection is managed by the accumulated injection time after the liquid surface reaches the reference level. |
