In order to obtain electrolyzed water for sterilization and disinfection by the electrolyzed water generation apparatus of the present invention, that is, to obtain hypochlorous acid-containing electrolyzed water, the concentration of hypochlorous acid in the generated water, that is, the residual water in the generated water, It is necessary to add a halogen compound such as salt (NaCl) to the water to be treated in order to increase the chlorine concentration. When the water to be treated, in which a halogen compound such as salt (NaCl) is added to the water to be treated, is electrolyzed, not only hydrogen and oxygen are emitted from the pair of electrodes 2, but chlorine gas harmful to the human body is emitted from the anode side. (Cl ₂ ) will be generated in large quantities.
Therefore, after the container 1 is closed to the lower case 13 via the elastic body 8 and electrolyzed to generate water, when the user removes the container 1 from the lower case 13 It is dangerous if the chlorine gas is brought into contact with the mucous membrane of the eye and throat, but by providing the gas vent 9 as described above, the gas is diffused and released from the gas vent 9 to the outside during generation.

Reference numeral 7 denotes a capacitor for smoothing the output. Reference numeral 50 denotes a control DC power supply (three-terminal regulator) for obtaining a DC voltage supplied to a controller constituting the control means 3.
It is. The control means 3 determines whether the electrode 2 is immersed in the water to be treated.
Reference numerals 1 and 2 denote current detection resistors, and reference numerals 52 and 53 denote current detection resistors and transistors for detecting when an overcurrent flows due to a short circuit between the electrodes 2 for some reason. 5 is a generation switch, and 54 and 56 are current limiting resistors. Reference numeral 57 denotes a current detection resistor for detecting an electrolytic current at the time of generation disclosure and outputting a signal corresponding to the current value to the control unit 3 by a current detection circuit (op-amp) 55. The current detection resistor 57 It constitutes current detection means. Reference numeral 58 denotes a polarity inversion circuit, and the polarity inversion circuit 5
The polarity of each of the pair of electrodes 2 is alternated by the control means 3 through 8. Reference numerals 59 and 60 denote electrolytic capacitors for backup in case of an instantaneous power failure or the like.

Thus, the user puts the salt (Na) in the container 1.
A predetermined amount of a halogen compound such as Cl) and an organic acid (acetic acid or the like) for adjusting the pH of the produced water are added, tap water is poured into the vessel 1 up to a predetermined draft line, and the vessel is stirred. . Here, p is added by adding an organic acid for pH adjustment.
H is adjusted to, for example, 4 to 6. And p
The relationship between H and the chlorine component abundance ratio in water is that chlorine component exists in water in three forms,
H determines their existence ratio. Of these three forms, Cl ₂ is a volatile active ingredient and is easily volatilized from water. Further, of the remaining two forms, hypochlorous acid (HOCl) is OCl ^- exhibits a very high bactericidal power than. By setting the pH in the range of 4 to 6, water containing a large amount of hypochlorous acid (HOCl) can be generated. Therefore, as described above, the pH is set in the range of 4 to 6 and hypochlorous acid (HOCl) is used. Can be said to be suitable as sterilizing washing water. For this reason, in the present embodiment, a predetermined amount of an organic acid (such as acetic acid) for pH adjustment is added as described above.

After the container 1 is mounted on the main body B as described above, the switch operation section 29 provided on the upper case 10 is operated to operate the tact switch 28 constituting the generation switch 5 to turn it on. , A current flows between the electrodes 2 through the polarity inversion circuit 58. At this time, after the time required for stabilizing the electrolytic current has elapsed (for example, 0.3
Second), the current detecting resistor 57 constituting the electrolytic current detecting means.
And outputs a signal to the control means 3 in accordance with the electrolytic current by a current detection circuit (operational amplifier) 57 via the control circuit 3. The control means 3 controls the electrolysis time based on this signal.
A current flows between the electrodes 2 through the polarity inversion circuit 58, and the water to be treated is electrolyzed for a predetermined time controlled by the control means 3.
At this time, the LED constituting the notification means 6 is lit in green to notify that the data is being generated.

Further, during the generation, the control means 3 controls the polarity of the opposing electrodes 2 via the polarity inversion circuit 58 so as to alternate. Here, in the embodiment, when one side of the pair of electrodes 2 is viewed, the polarity inversion control is performed so that the total of the energizing time as the anode and the total of the energizing time as the cathode are substantially equal.

When one side of the pair of electrodes 2 is viewed, the control means 3 may control the polarity at the start of generation to be different from the polarity at the time of completion of the previous generation. In other words, when one side of the pair of electrodes 2 is viewed, for example, when generation is completed by acting as an anode, when the next generation starts, it is controlled by the control means 3 via the polarity inversion circuit 58 so as to act as a cathode. Is also good. in this case,
When one side of the pair of electrodes 2 is viewed, for example, the pair of electrodes 2 may be controlled to act as an anode during the previous full generation period and to act as a cathode during the next full generation period.
When looking at one side, for example, the anode during the previous generation period, if acting as an anode at the end of generation by acting alternately as a cathode, act as a cathode at the start of the next generation, the anode during the next generation, as a cathode You may make it act alternately.

The adhesion of the scale to the cathode side (mainly calcium carbonate (CaC
O ₃ )) can be automatically prevented and the electrolytic performance can be maintained. Then, as in the above embodiment, when one side of the pair of electrodes 2 is viewed, the effect time is remarkable because the operation time as the anode is substantially equal to the operation time as the cathode.

When the generation is completed, the LED constituting the notification means 6 is controlled by the control means 3 so as to notify that the generation has been completed, instead of lighting from green to blinking green. During the generation and after the generation is completed, that is, while the generation and the completion of the generation are notified by the LED constituting the notification unit 6 for notifying the generation and the completion of the generation, a tact switch constituting the generation switch 5 is provided. 28 is controlled by the control means 3 so as not to be accepted.

Here, the tact switch 28 constituting the generating switch 5 can be received again only when the electrode 2 is once pulled out of the water to be treated, released from the submerged state, and then re-submerged. It is. This is the water detection circuit 6
The control means 3 detects whether or not the electrode 2 is submerged in the water to be treated by the current detection resistor 51, and when the control means 3 determines that the current value between the electrodes 2 is zero, the control means 3 resets the generation switch 5 again. The constituent tact switch 28 can be received.

In this manner, during the generation and after the completion of the generation, the tact switch 28 constituting the generation switch 5 is not accepted by erroneously operating the switch operating section 29. In such a case, the generated water is not greatly different from the residual chlorine concentration. Also, the switch operation unit 29 is operated to turn on the tact switch 28 constituting the generation switch 5, and the electrolysis is started, and after a time (for example, 0.3 seconds) necessary for stabilizing the electrolytic current has elapsed, If the water to be treated is extremely small and the electrode 2 is not submerged in the water to be treated, or if there is no water to be treated by mistake, the current value between the electrodes 2 is determined by the water detection circuit 61 described above. Is zero, the LED constituting the generation failure notification means 4 is lit, for example, in red to notify that generation is impossible, and the polarity determination circuit 58 is turned off. To stop the electrolysis.

In addition, if the water to be treated contains a halogen compound (salt or the like) in a predetermined amount or less or a predetermined amount or more, or the conductivity of water changes due to water quality change or water temperature change, the electrolytic current When the value falls below or exceeds a predetermined value, a current detecting circuit (op-amp) is connected via a current detecting resistor 57 constituting an electrolytic current detecting means.
A signal indicating that the electrolysis current is other than a predetermined value is output to the control means 3 by the control signal 57, and the control means 3 illuminates, for example, the LED constituting the generation impossible notification means 4 in red, thereby notifying that the generation is impossible. Further, the polarity determination circuit 58 is turned off to control the electrolysis to be stopped.

Further, for safety and circuit protection, the electrode 2
When a short circuit occurs for some reason and an overcurrent flows between the electrodes 2, the current is detected by the current detecting resistor 52 and the transistor 53, and the control means 3 determines that the current is an overcurrent and forms an LED that constitutes the generation failure notification means 4. Illuminates in red, for example, to notify that generation is impossible, and to control the electrolysis to be stopped by turning off the polarity determination circuit 58.

The determination of the presence / absence of water in the water detection circuit 61 by the overcurrent detection and current detection resistors 51 is controlled so that the control means 3 always receives the water during the generation. Table 1 below summarizes the set value of the electrolysis time according to the magnitude of the electrolysis current flowing between the electrodes 2 and the operation when the abnormal current value is detected as an example.

[0032]

[Table 1]

As described above, even if the generation time is controlled by detecting the electrolytic current value, the lower end of the electrode 2 is in contact with the bottom surface of the container 1 or the distance between the electrodes 2 is not secured at a predetermined distance. In the case, when the water to be treated is extremely smaller than the predetermined amount,
Assuming that the electrolysis current value entered the same table as compared to the case where a predetermined amount of water was put in and the electrolysis time was the same and the electrolysis time was generated, the amount of water was small, so the residual chlorine concentration was higher than the target residual chlorine concentration. Produced water may be obtained.

However, in the present invention, as shown in FIG. 1, when the bottom surface of the container 1 is in a horizontal state, the electrode 2 is held by the electrode holding portion 36 so as to be perpendicular to the bottom surface of the container 1. There is a predetermined distance between the lower end of the electrode 2 and the bottom surface of the container 1 and a predetermined distance between the electrodes 2. In such a case, the amount of the electrode 2 embedded in the water to be treated. The electrode 2 is immersed in the water to be treated when the amount of the water to be treated is extremely smaller than a predetermined amount, since the electrolysis current value is also changed and the electrolysis time is restricted by the electrolytic current value. The electrolysis current is determined to be a value other than the predetermined value because the electrolysis current does not become very small or the electrolysis current becomes extremely small. Not something .

In one embodiment of the present invention, the residual chlorine concentration of the produced water is set to 50 to 100 ppm, and the pH is set to about 4 to 6. Needless to say, the present invention is not limited to these numerical values, and any target values can be set for both the residual chlorine concentration and the pH. In the above embodiment, the pH is adjusted by adding an organic acid (such as acetic acid) for adjusting the pH.
Has been described as an example in which the pH is adjusted to 4 to 6. When an organic acid (such as acetic acid) for pH adjustment is not added, the pH is alkaline when electrolyzed, but in the present invention, an organic acid is added. Instead, the present invention can be applied to the case where the water to be treated in which salt and water are mixed is electrolyzed.

After the electrolyzed water containing hypochlorous acid is generated as described above, the container 1 is removed from the main body B, and a sprayer 15 as a spray means is detachably attached to the container 1 as shown in FIG. Attached and sprayed with an electrolyzed water containing hypochlorous acid by a sprayer 15 for sterilization and disinfection. During the operation of removing the container 1 from the main body B and attaching the atomizer 15, as described above, the chlorine gas generated during the generation is dispersed and diffused to the outside. No danger is caused by contact with the mucous membrane of the throat or throat.

[0037]

According to the first aspect of the present invention, as described above, the container for storing the water to be treated and the insoluble electrodes having opposite polarities and disposed opposite to each other in the container. It is a device for generating electrolyzed water containing hypochlorous acid by electrolyzing the water to be treated in the container, so that the spraying means can be detachably attached to the container. When spraying and using electrolyzed water containing hypochlorous acid, the spraying means can be directly attached to the container of the electrolyzed water generator and used as a spray. There is no need to transfer the electrolyzed water containing hypochlorous acid from the generator to the container of the atomizer, without spilling the electrolyzed water containing hypochlorous acid to the outside, and there is no need for time for transfer Is very convenient Selfishness is a good thing.
