Here, the tap water for dilution used for diluting the stock solution is supplied to the tap water tank 13 for measuring the tap water through the water receiving plug 10, the electromagnetic valve 12, and the water supply path 11. In the present embodiment, tap water is supplied to the detection position b of the liquid level sensor 18 in the tap water tank 13.
On the other hand, the stock solution is supplied from the stock solution cartridge 20 to the stock solution metering unit 23 by the pump 22. In the stock solution metering unit 23, the stock solution is supplied to the detection position b of the liquid level sensor 24. Thereafter, the control unit 50 opens the first electromagnetic valve 25a or the second electromagnetic valve 25b. As a result, the stock solution in the stock solution metering unit 23 falls by its own weight and is supplied to the first sterilizing water tank 30 or the second sterilizing water tank 33.

  The opened first electromagnetic valve 25a or second electromagnetic valve 25b is closed after the supply of the stock solution is completed. Thereafter, the stock solution metering unit 23 supplies the stock solution again to the stock solution metering unit 23 to prepare for the next stock solution supply. In the present embodiment, the supply of the stock solution to the first sterilizing water tank 30 or the second sterilizing water tank 33 is repeated a predetermined number of times. For example, when producing sterilizing water such as gargle water, a stock solution for one metered amount is supplied to the first sterilizing water tank 30 or the second sterilizing water tank 33, but sterilizing water with enhanced sterilizing effect is produced. In this case, the undiluted solution for twice or three times measurement is supplied to the first sterilizing water tank 30 or the second sterilizing water tank 33.

  Further, in the present embodiment, tap water in the tap water tank 13 (tap water reaching the detection position b of the liquid level sensor 18) after supplying the stock solution to the first sterilizing water tank 30 or the second sterilizing water tank 33. ) Is supplied to the first sterilizing water tank 30 or the second sterilizing water tank 33 by opening the first electromagnetic valve 16a or the second electromagnetic valve 16b. Here, this supply is performed by utilizing the own weight of tap water.

  When the tap water is supplied to the first sterilizing water tank 30 or the second sterilizing water tank 33, the first three-way electromagnetic valve 41a or the second three-way electromagnetic valve 41b is opened. Thereby, the discharge of air from the first sterilizing water tank 30 or the second sterilizing water tank 33 is performed more smoothly.

  Here, when tap water is supplied to the first sterilizing water tank 30 or the second sterilizing water tank 33, the air corresponding to the volume of the tap water is discharged from the first sterilizing water tank 30 or the second sterilizing water tank 33. Is done. In this case, when the first three-way electromagnetic valve 41a or the second three-way electromagnetic valve 41b is opened, air is smoothly discharged from the first sterilizing water tank 30 or the second sterilizing water tank 33. In addition, the air discharged | emitted from the 1st sterilization water tank 30 or the 2nd sterilization water tank 33 passes the normal opening (normal open port) of the 1st three-way solenoid valve 41a or the 2nd three-way solenoid valve 41b, and a sterilization water production | generation apparatus 1 is smoothly discharged into the interior.

  In the above description, an example in which the tap water is supplied after supplying the stock solution to the first sterilizing water tank 30 or the second sterilizing water tank 33 has been described. However, the first sterilizing water tank 30 or the second sterilizing water tank is described. The supply of the stock solution and the supply of tap water to 33 may be performed in parallel. Further, for example, the stock solution may be supplied after the tap water is supplied. As in this embodiment, the supply of the stock solution is performed first, and then the tap water is supplied in the case where the stock solution and the tap water are supplied in parallel, or the tap water is more than the stock solution. As compared with the case where the liquid is supplied first, the stock solution and the tap water are mixed more effectively.

Next, the operation of each part when the generated sterilizing water is supplied to the outside will be described.
When the sterilizing water is supplied to the outside, first, the compressed air is supplied into the first sterilizing water tank 30 or the second through the first compressed air supply / exhaust passage 42a or the second compressed air supply / exhaust passage 42b. It is supplied into the sterilizing water tank 33. When compressed air is supplied into the first sterilizing water tank 30 or the second sterilizing water tank 33, the inside of the first sterilizing water tank 30 or the second sterilizing water tank 33 is in a pressurized state, and the first sterilizing water tank 33 The sterilizing water in the water tank 30 or the second sterilizing water tank 33 is supplied to the outside of the sterilizing water generator 1.

  More specifically, when the first sterilizing water tank 30 or the second sterilizing water tank 33 is pressurized, the sterilizing water is supplied from the first sterilizing water supply path 31 or the second sterilizing water supply path 35 and the manifold. Via 45, the supply plug 47 is supplied. Then, it is supplied to the outside of the sterilizing water generator 1 through the supply plug 47.

  In addition, although description was abbreviate | omitted above, in this embodiment, while supplying sterilization water from either one of the 1st sterilization water tank 30 and the 2nd sterilization water tank 33, this one sterilization water is performed. When the water tank is empty, it is switched to the other sterilizing water tank. Thereby, supply of sterilizing water will not be delayed. When switching to the other sterilizing water tank, generation of sterilizing water is started in the one sterilizing water tank. Then, when the other sterilizing water tank becomes empty, switching to one sterilizing water tank is performed.

  Whether or not the sterilizing water tank is empty is determined based on the detection of the liquid level at the detection position c provided in each of the liquid level sensor 32 and the liquid level sensor 34. In addition, the switching of the sterilizing water tank is performed by opening / closing the first three-way solenoid valve 41a provided on the first compressed air supply / exhaust passage 42a and the second compressed air supply / exhaust passage 42b. 2 Opening / closing the three-way electromagnetic valve 41b, opening / closing the first electromagnetic valve 36a provided on the first sterilizing water supply path 31, and the second electromagnetic valve provided on the second sterilizing water supply path 35 This is done by opening / closing 36b.

  Further, in the present embodiment, when switching from one sterilizing water tank to the other sterilizing water tank as the sterilizing water is consumed, the sterilizing water supplied to the outside is restrained from pulsation and a decrease in flow rate. The first electromagnetic valve 36a and the second electromagnetic valve 36b are controlled so that sterilized water is simultaneously supplied from the two sterilized water tanks for a predetermined time (several msec). In addition, control is performed to overlap the supply timing at which sterilizing water is supplied between one sterilizing water tank and the other sterilizing water tank.
