When the flow of water is started and the tap water is collected in the water guide section 7 and the flow detection sensor 11 detects the start of water flow, a voltage is applied between the pair of electrodes 5 in the electrolytic cell 8 by the battery 9 and the electric circuit 15.

間が短くなることがわかる。FIG. 3 is a graph showing the relationship between the electrical conductivity of tap water and the chloride ion concentration in the first embodiment, and FIG. 4 is a graph showing the relationship between each chloride ion concentration using the water purifier in the first embodiment of the present invention. It is a graph which shows the relationship between the current detection value detected by the current detector 13 when flowing tap water, and the chlorine generation rate. FIG. 3 indicates that the higher the electric conductivity, the higher the chloride ion concentration. Also, from FIG. 4, it can be seen that the detected current value and the chlorine generation rate are almost proportional, and therefore the chlorine generation rate can be predicted from the detected current value. Therefore, based on the relationship between the detected current value and the generation rate of chlorine, the energizing time for the detected current value per unit time is set so that the residual chlorine concentration in the stagnant water of the water guide unit 7 of the water purifier 1 becomes an appropriate concentration. Then, an energization control program is built in the microcomputer 14. FIG. 5 is a graph showing the relationship between the detected current value and the energization time between the pair of electrodes 5 that is determined once by the energization control program of the microcomputer 14 according to the detected current value and executed once an hour. FIG.
From this, it is understood that the larger the current detection value, the shorter the energizing time per unit time.

制御される。Since the energization control program as described above is incorporated in the microcomputer 14, when energization is started between the pair of electrodes 5 and a current detection value detected by the current detector 13 is transmitted to the microcomputer 14. The energization control program determines the energization time to be performed once an hour according to the detected current value, and the energization is performed. Thereby, the concentration of residual chlorine in the stagnant water in the water guide section 7 is controlled within a certain range.

Water is usually passed about 1 to 5 times a day, but in this case, the water flow time is less than 1 hour, so that the power is supplied earlier. In the case where the water flow time is short in this manner, power is supplied according to a power supply control program in units of one hour, and the growth of general bacteria is suppressed.

とができる。First, the program of the energization time per unit time shown in FIG. 5 of the first embodiment is set as the standard mode. Further, the energization time twice as long as the standard mode is set as the high mode, and the energization time half as long as the standard mode is set as the low mode. The microcomputer 14 incorporates an energization control program for each mode. The selection of each mode is performed by the user operating the switch 17 according to the preference or use.
When the high mode is selected, the amount of generated chlorine is larger than that in the standard mode, so that the sterilizing power is increased. When the low mode is selected, the amount of generated chlorine is smaller than that in the standard mode, so that drinking water having a low residual chlorine concentration can be obtained even if the initial water flow time is short. The selected mode, the detected current value, the predicted value of the life of the battery 9, and the like are displayed on the liquid crystal panel 16, so that information can be obtained as needed by the user.

てもあわせて同様に実施した。After a new cartridge 2 is set in the water purifier 1 shown in FIG. 1, a flow rate of about 30 liters and 2 liters per minute using tap water having an electric conductivity of 85 μS / cm, a chlorine ion concentration of 12 mg / L and a pH of 6.8 is used. Water was passed at the water speed. Normally, in the case of a new cartridge 2 or in a state where the water purifier 1 is used every day, it is considered that the growth due to the general bacterial contamination in the stagnant water of the water guide part 7 is hardly recognized. Therefore, the general bacterium was injected into the stagnant water. As an injection method, heat-sterilized tap water was added to tap water previously pumped in a beaker for 48 hours, and a diluted solution was adjusted to a general bacterial concentration of 100 CFU / mL with a 1 mL sterile pipette, and the dilution was adjusted. A method of injecting the liquid into the water guiding section 7 so as not to spill was adopted. After 24 hours, 30 L of water was passed at a flow rate of 2 L per minute. At this time, 2 L of the initial water flow was divided into 0.2 L of beakers which had been sterilized by heating, and the number of viable bacteria and the concentration of residual chlorine were examined. In addition, in order to grasp the bacteriostatic effect of the energization, a comparative experiment without the energization was similarly performed.

At 6 CFU / mL in L, the water quality was far below the standard for tap water from the beginning, and reached 0.4 CFU / mL after 0.4 L.
In the standard mode and the high mode energization time, no viable bacteria were confirmed in all initial water flows from 0 to 2 L.

It can be seen from FIG. 5 that the energizing time per unit time is 10 minutes, and the current capacity consumed per day is calculated as 6.4 mA · h from (Equation 1). The current capacity of one AA alkaline battery is about 2
Since it is 500 mA · h, assuming that 2000 mA · h of the total current capacity of the battery 9 can be used as an energizing current between the pair of electrodes 5 when applying a voltage, the life of the battery 9 is given by (Equation 2). Calculated as 312.5 days. When the life of the battery 9 in each mode is calculated using this value, the energization time in the low mode is half of that in the standard mode, and the life of the battery 9 is 625 days, which is twice as long as that in the standard mode. Since the time is twice as long as that in the standard mode, the life of the battery 9 is calculated to be 156.25 days, which is half that in the standard mode.
