  FIG. 5 is a functional block diagram showing the function of the electrolyzed water distribution device D in blocks. The electrolyzed water spraying apparatus D is equipped with the control part 30 which controls the electrolyzed water spraying apparatus D whole, such as the electrolyzed water production | generation part 5 and the spraying part 19. As shown in FIG. The control unit 30 is provided, for example, on the back side of an operation panel provided on the top surface of the main body case 1 (see FIG. 1). The electrolyzed water dispersion device D also has a carbon dioxide calculation means 51, which is connected to the control unit 30.

  The carbon dioxide calculating unit 51 includes a carbon dioxide detecting unit 52 that detects carbon dioxide and a carbon dioxide estimating unit 53 that estimates the concentration of carbon dioxide from the value of the carbon dioxide detecting unit 52, and acquires the concentration of carbon dioxide .

  The carbon dioxide detection means 52 is provided at a place not affected by air containing electrolyzed water (or active oxygen species) blown out from the blowout port 6. Thereby, the density | concentration of the carbon dioxide in the place where the electrolyzed water spraying apparatus D was installed can be grasped | ascertained correctly.

  The control unit 30 includes a purification capacity determination unit 54 and a generation control unit 34.

  The generation control unit 34 controls the generation of electrolyzed water in the electrolysis unit 17. Specifically, in the electrolysis unit 17, one cycle is repeated by setting the conduction time for conducting electricity to electrolyze the electrode members of the electrolytic unit 17 and the non-energization time after the termination of the conduction as one cycle. Produce electrolyzed water.

  The purification capacity determination unit 54 determines the generation condition of the electrolyzed water in the electrolysis unit 17 and the blower unit 7 based on the purification capacity level determined from the carbon dioxide concentration acquired by the carbon dioxide calculation unit 51 every air volume unit time. Determine the air volume. The electrolyzed water production conditions are an energization time and a non-energization time in one cycle of producing the electrolyzed water, and an electric energy in the energization time.

  FIG. 6 shows an example of the relationship between the carbon dioxide concentration and the purification capacity level, and the purification capacity determination unit 54 determines the purification capacity level of the electrolyzed water spray device D based on this.

  As shown in FIG. 6, the concentration range of carbon dioxide acquired from the carbon dioxide calculating means 51 and the purification level are associated with each other. In the example of FIG. 6, the purification capacity level is indicated in three stages of LV1 to LV3, and the purification capacity level is set to be higher as the concentration of carbon dioxide is higher. If the ventilation volume of the room in which the electrolyzed water distribution device D is disposed is insufficient, the concentration of carbon dioxide in the room increases due to the influence of carbon dioxide discharged from the breathing of the occupant.

  FIG. 7A shows an example of the relationship between the purification capacity level and the air volume, and the air purification capacity determination unit 54 determines the air volume of the electrolyzed water spray device D based on this.

  As shown to Fig.7 (a), the purification capacity level and the air volume are linked | related. In the example of FIG. 7A, the air volume is shown in three stages from 1. The higher the purification capacity level, the larger the air volume is set. When the air volume increases, the amount of reactive oxygen species contained in the air blown out from the blowout port 6 increases, so many viruses can be inactivated.

  FIG. 7B shows an example of the relationship between the purification capacity level and the electric energy, and the electric capacity of the electrolyzed water spraying device D is determined in the purification capacity determination unit 54 based on this.

  As shown in FIG. 7 (b), the purification capacity level and the amount of power are associated. In the example of FIG. 7B, the magnitude of the current (electrode current) to be supplied to the electrode member is defined as the amount of power to be determined. The electrode current is shown in three stages 1 to 3. The higher the purification capacity level, the larger the electrode current is set. By controlling the voltage applied to the electrode member so that the current flowing to the electrode member becomes the determined current, the amount of power during the energization time is determined. By increasing the amount of power in the current application time, electrolyzed water containing a larger amount of active oxygen species is generated. Furthermore, since the amount of reactive oxygen species contained in the air blown out from the blowout port 6 also increases, many viruses can be inactivated.

  FIG. 7C shows an example of the relationship between the purification capacity level and the energization time, and the purification capacity determination unit 54 determines the energization time of the electrolyzed water spray apparatus D based on this.

  As shown in FIG. 7 (c), the purification capacity level and the energization time are associated. In the example of FIG. 7C, the energization time is shown in three stages of 1 to 3, and the higher the purification capacity level, the longer the energization time. If the current application time disappears, electrolytic water containing a larger amount of active oxygen species is produced. Furthermore, since the amount of reactive oxygen species contained in the air blown out from the blowout port 6 also increases, many viruses can be inactivated.

  FIG. 7D shows an example of the relationship between the purification capacity level and the non-energization time, and the purification capacity determination unit 54 determines the energization time of the electrolyzed water spray apparatus D based on this.

  As shown in FIG. 7D, the purification capacity level and the non-energization time are associated. In the example of FIG. 7D, the non-energization time is shown in three stages of 1 to 3. The higher the purification capacity level, the shorter the non-energization time. If the non-energization time becomes short, the energization time in one cycle of generating the electrolyzed water becomes longer, and electrolyzed water containing a larger amount of active oxygen species is generated per cycle. Furthermore, since the amount of reactive oxygen species contained in the air blown out from the blowout port 6 also increases, many viruses can be inactivated.

  FIG. 7 (e) shows an example of the relationship between the purification capacity level and the air volume and the electrolytic water generation condition. Based on the purification capacity determination unit 54, the air volume and the electrolytic water generation condition of the electrolytic water dispersion device D are shown. Decide.

  As shown in FIG. 7E, the purification capacity level is associated with the air volume and the electrolyzed water generation condition. In the example of FIG. 7E, as the air volume and the electrolyzed water generation condition to be determined, the energization time and non-energization time in one cycle of producing the electrolyzed water, and the electric energy in the energization time are defined. Air volume and electrolyzed water generation conditions are shown in three stages 1 to 3. The higher the purification capacity level, the more the electrolyzed water is generated per cycle of electrolyzed water generation, and the electrolyzed water containing a large amount of active oxygen species is generated. Is set as

  Further, although FIG. 7 (e) shows a combination of all of FIGS. 7 (a) to 7 (d), it may be a combination of plural pieces.

  The change of the air volume is determined every air volume unit time (for example, 5 minutes).

  The amount of power is changed each time the power is on. On the other hand, if de-energized, it is changed from the next energization.

  As for the conduction time, if current is being supplied, the current conduction time is compared with the current conduction time after the change, and it is determined whether to continue the conduction or to stop the conduction and switch to the non-conduction. On the other hand, if de-energized, it is changed from the next energization.

  As for the non-energization time, if non-energization is being performed, the current non-energization time is compared with the non-energization time after the change, and it is determined whether to continue de-energization or to end de-energization and switch to energization. On the other hand, if the power is on, it is changed from the next time the power is not on.

  As described above, in the electrolyzed water dispersion apparatus D according to the first embodiment, on the basis of the value of the carbon dioxide calculation means 51, the current application time to the electrolytic unit 17 in one cycle of producing electrolyzed water The energization time, the amount of power during the energization time, and the air volume of the blower 7 are determined.

  As a result, an optimum amount of reactive oxygen species can be generated according to the use environment of the electrolyzed water spraying apparatus D, and furthermore, the amount of reactive oxygen species contained in the air blown out from the outlet 6 also increases. It can inactivate the virus.

  Moreover, the electrolyzed water dispersion apparatus D of this embodiment determines the electricity supply time, the non-energization time, and electric energy as production conditions of electrolyzed water. Thus, if it is desired to increase the amount of active oxygen species contained in the electrolyzed water according to the carbon dioxide concentration, it is possible to lengthen the energizing time, shorten the deenergizing time, or increase the electric energy. The amount of reactive oxygen species produced can be easily adjusted.

Second Embodiment
Next, with reference to FIGS. 8 and 9, an electrolyzed water dispersion apparatus D according to a second embodiment of the present invention will be described. The electrolyzed water dispersion apparatus D of the first embodiment is, based on the value of the carbon dioxide calculating means 51, an energization time to the electrolytic unit 17 in one cycle of producing electrolyzed water, a non-energization time after the energization, and an energization time The amount of electric power in the air flow and the air flow rate of the blower 7 were determined. On the other hand, the electrolyzed water dispersion apparatus D of the second embodiment supplies electricity to the electrolyzing unit 17 in one cycle of producing electrolyzed water based on the value of the carbon dioxide calculating unit 51 and the value of the activity determining unit 55. The time, the non-energization time after the energization, the power amount in the energization time, and the air volume of the blower unit 7 are determined.

  Hereinafter, the electrolyzed water dispersion apparatus D of the second embodiment will be described focusing on differences from the electrolyzed water dispersion apparatus D of the first embodiment. About the structure same as the electrolyzed water spraying apparatus D of 1st Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  FIG. 8 is a functional block diagram showing the function of the electrolyzed water distribution device D of the second embodiment in blocks. The electrolyzed water dispersion apparatus D of this embodiment includes a purification capacity determination unit 57 in place of the purification capacity determination unit 54 of the electrolyzed water dispersion apparatus D of the first embodiment. Not only the value of the carbon dioxide calculation unit 51 but also the value of the activity amount determination unit 55 are input to the purification capacity determination unit 57.

  The activity amount determination unit 55 may determine the activity amount from the amplitude and time of the output signal of the pyroelectric infrared sensor as the human detection unit 56.

  The purification capacity determination unit 57 is based on the carbon dioxide concentration acquired by the carbon dioxide calculation unit 51 and the purification capacity level determined from the amount of activity of the person acquired by the activity amount determination unit 55 every air volume unit time. The generation condition of the electrolytic water in the electrolytic unit 17 and the air volume of the blower unit 7 are determined.

  FIG. 9 shows an example of the relationship between the carbon dioxide concentration, the activity amount, and the purification capacity level, and the purification capacity determination unit 57 determines the purification capacity level of the electrolyzed water spray device D based on this.

As shown in FIG. 9, the concentration range of carbon dioxide acquired from the carbon dioxide calculating unit 51, the activity amount of a person acquired from the activity amount determining unit 55, and the purification level are associated. In the example of FIG. 6, the activity amount is shown in two stages of large and small, the purification capacity level is shown in three stages of LV1 to LV3, and the threshold of carbon dioxide concentration is changed according to the size of the activity. . Even if the carbon dioxide concentration is lower as the activity amount is larger, the purification capability level is set to be higher.
That is, the relationship between the threshold position A3 where the activity amount is “large” and the purification capacity level is LV3 and the threshold position A2 where the activity amount is “small” and the purification capacity level is LV3 is A3 <A2.

  The relationship between the purification capacity level, the generation condition of the electrolyzed water in the electrolysis unit 17 and the air volume of the blower unit 7 is the same as that of the electrolyzed water dispersion device D of the first embodiment.

  In the room where the electrolyzed water distribution device D is disposed, when the activity amount of the occupant increases, the concentration of carbon dioxide discharged from the respiration of the occupant increases. On the other hand, since the distance between the electrolyzed water spraying apparatus D and the occupant is far, there may be a time difference until the carbon dioxide concentration is diffused. Therefore, it can be detected that the activity amount is high, and the purification capacity level can be increased before the carbon dioxide concentration becomes high.

  As described above, in the electrolyzed water dispersion apparatus D according to the second embodiment, based on the value of the carbon dioxide calculating unit 51 and the value of the activity determining unit 55, the electrolyzing unit 17 in one cycle of generating electrolyzed water is generated. The energization time, the non-energization time after the energization, the power amount in the energization time, and the air volume of the blower unit 7 are determined.

  As a result, an optimum amount of reactive oxygen species can be generated according to the use environment of the electrolyzed water spraying apparatus D, and furthermore, the amount of reactive oxygen species contained in the air blown out from the outlet 6 also increases. It can inactivate the virus.

  Moreover, the electrolyzed water dispersion apparatus D of this embodiment uses the relationship between the carbon dioxide concentration, the activity amount, and the purification capacity level. The activity of the student causes an increase in the respiration rate of the student and an increase in carbon dioxide concentration. Therefore, by detecting the amount of activity of the employee, it is possible to change the purification ability level earlier by the amount of carbon dioxide diffusion. As a result, an optimum amount of reactive oxygen species can be generated according to the use environment of the electrolyzed water spraying apparatus D, and furthermore, the amount of reactive oxygen species contained in the air blown out from the outlet 6 also increases. It can inactivate the virus.

Third Embodiment
Then, with reference to FIG. 10, the electrolyzed water dispersion apparatus D which is 3rd Embodiment of this invention is demonstrated. In the electrolyzed water dispersion apparatus D of the second embodiment, the generation conditions of the electrolyzed water and the air volume of the blower 7 were determined based on the value of the carbon dioxide calculating unit 51 and the value of the activity determination unit 55. On the other hand, the electrolyzed water dispersion apparatus D of the third embodiment calculates the carbon dioxide concentration from the output of the hydrogen detection means 59, instead of the carbon dioxide detection means 52.

  Hereinafter, the electrolyzed water scattering device D of the third embodiment will be described focusing on differences from the electrolyzed water spraying device D of the second embodiment. About the structure same as the electrolyzed water dispersion apparatus D of 2nd Embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  FIG. 10 is a functional block diagram showing the functions of the electrolyzed water distribution device D of the third embodiment in blocks. The electrolyzed water dispersion apparatus D of the present embodiment includes carbon dioxide calculation means 58 in place of the carbon dioxide calculation means 51 of the electrolyzed water dispersion apparatus D of the second embodiment. The carbon dioxide calculating means 58 comprises a hydrogen detecting means 59 and a human discharge carbon dioxide estimating means 60. The human discharge carbon dioxide estimating means 60 estimates the carbon dioxide concentration from the value of the hydrogen detecting means 59 based on the relationship between the hydrogen concentration in human breath and the carbon dioxide concentration.

  As a result, the carbon dioxide concentration can be calculated by the hydrogen detection means in place of the carbon dioxide detection means, and the active oxygen species in an optimum amount can be generated more inexpensively according to the use environment of the electrolyzed water spraying device D Since the amount of reactive oxygen species contained in the air blown out from the blowout port 6 also increases, many viruses can be inactivated.

  As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited at all to the said embodiment, It is easy that various improvement deformation | transformation is possible within the range which does not deviate from the meaning of this invention. It can be guessed. For example, the numerical values listed in the above-described embodiments are merely examples, and it is naturally possible to adopt other numerical values.
