BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments for carrying out the present invention will be described with reference to the accompanying drawings.

(First embodiment)
First, an electrolyzed water spraying device D according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG. FIG. 1 is a perspective view of the electrolyzed water spraying device D, and is a view of the electrolyzed water spraying device D viewed from the front side. FIG. 2 is a perspective view of the electrolyzed water spraying device D, which is a front view of the electrolyzed water spraying device D with the panel 3 of FIG. 1 opened.

As shown in FIGS. 1 and 2, the electrolyzed water spraying device D includes a substantially box-shaped main body case 1 and has substantially rectangular intake ports 2 on both sides of the main body case 1 . An openable air outlet 6 is provided on the top surface of the main body case 1 . 1 and 2, the outlet 6 is in a closed state.

An openable and closable panel 3 is provided on a first main body side surface 1A, which is the right side surface (one side surface of the main body case 1) when viewed from the front side of the main body case 1. As shown in FIG. A panel 3 is provided with an intake port 2 on one side surface of the body case 1 . When the panel 3 is opened, a vertically long rectangular opening 4 appears. A water storage portion 14, a tank member 15, a tablet insertion case 18a, and the like, which will be described later, can be taken out from the opening 4. As shown in FIG.

FIG. 3 is a vertical cross-sectional view of the central portion of the electrolyzed water spraying device D when viewed from the front, and is a view of the electrolyzed water spraying device D as seen from the right side. FIG. 4 is a longitudinal sectional view of the right side of the electrolyzed water spraying device D when viewed from the front, and is a view of the electrolyzed water spraying device D as seen from the right side.

As shown in FIGS. 2, 3, and 4, the body case 1 includes an electrolyzed water generator 5, a tank member 15, a sprayer 19, and an air passage 8. As shown in FIGS. The electrolyzed water generating unit 5 includes a water storage unit 14, an electrolysis unit 17, an electrolysis promoting tablet input unit 18, and an input control unit 41 (see FIG. 5).

The water storage part 14 has a box shape with an open top, and has a structure capable of storing water. The water storage part 14 is arranged in the lower part of the main body case 1 , is horizontally slidable from the main body case 1 , and can be removed from the opening 4 . The water storage part 14 stores water supplied from the tank member 15 .

The electrolyzer 17 is provided with an electrode member (not shown), which is installed so as to be submerged in the water in the reservoir 14 . By energizing the electrode member, the electrolyzer 17 electrochemically decomposes the water containing chloride ions in the water reservoir 14 to generate electrolyzed water containing active oxygen species. Here, the active oxygen species refer to oxygen molecules having higher oxidation activity than normal oxygen and their related substances. For example, so-called narrowly defined active oxygen such as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide includes so-called broadly defined active oxygen such as ozone and hypochlorous acid (hypohalogenous acid).

In the electrolysis unit 17, one cycle includes an energization time for energizing the electrode member for electrolysis and a time after the energization is stopped, that is, a non-energization time that is a time during which the energization is not performed. Electrolyzed water is generated by repeating this process. If the energization time is longer than the non-energization time, electrolyzed water containing a larger amount of active oxygen species is produced per cycle. Also, if the non-energization time is made longer than the power-on time, the generation of reactive oxygen species per cycle can be suppressed. Furthermore, by increasing the amount of electric power during the energization time, electrolyzed water containing a larger amount of active oxygen species is produced. Although the details will be described later, the electrolyzed water spraying device D determines the energized time, the non-energized time, the electric power amount during the energized time, and the air volume of the air blower 7 based on the value of the carbon dioxide calculation means 51. . As a result, an optimum amount of reactive oxygen species can be generated according to the usage environment.

The electrolysis promoting tablet input unit 18 includes a tablet input case 18a, a tablet input member (not shown) provided in the tablet input case 18a, and a tablet input cover 18b detachably provided on the top of the tablet input case 18a. It has The tablet charging case 18 a is configured to be removable from the opening 4 . By removing the tablet charging cover 18b from the taken-out tablet charging case 18a, the user can load the electrolysis enhancing tablets into the tablet charging case 18a.

When the tablet loading member rotates, the electrolysis-enhancing tablet drops into the reservoir 14 through a drop opening (not shown) in the bottom of the tablet loading case 18a. By dissolving the electrolysis-promoting tablet in the water in the water storage part 14, the water in the water storage part 14 becomes water containing chloride ions. An example of an electrolysis promoting tablet is sodium chloride.

The input control unit 41 is provided, for example, in the vicinity of the drop opening on the bottom surface of the tablet input case 18a, and controls input of the electrolysis-enhancing tablet by the electrolysis-enhancing tablet input unit 18. FIG. When the control unit 30 (to be described later) gives an instruction to insert an electrolysis-enhancing tablet, the input control unit 41 starts rotating a tablet input member provided in the electrolysis-enhancing tablet input unit 18 . Then, the input control unit 41 determines whether or not there is an electrolysis-enhancing tablet dropped from the tablet-input case 18a into the water storage unit 14, and when it determines that the electrolysis-enhancing tablet has dropped from the tablet-input case 18a into the water storage unit 14, the tablet is input. Stop rotating the member.

Note that the electrolyzed water spraying device D does not have to have the electrolysis enhancing tablet input unit 18 and the input control unit 41 .

The tank member 15 is attached to a tank holding portion 14 a provided on the bottom surface of the water storage portion 14 . The tank member 15 includes a tank 15a for storing water and a lid 15b provided at an opening (not shown) of the tank 15a. An opening/closing part (not shown) is provided in the center of the lid 15b.

Specifically, when the opening of the tank 15a faces downward and the tank member 15 is attached to the tank holding portion 14a of the water storage portion 14, the opening/closing portion is opened by the tank holding portion 14a. That is, when the tank member 15 is filled with water and attached to the tank holding portion 14a, the opening/closing portion is opened and water is supplied to the water storage portion 14, so that the water storage portion 14 is filled with water. When the water level in the water storage part 14 rises and reaches the lid 15b, the opening of the tank member 15 is water-sealed, so that the water supply is stopped, water remains inside the tank member 15, and the water level in the water storage part 14. The water inside the tank 15a is supplied to the water storage portion 14 every time the temperature drops. That is, the water level in the water reservoir 14 is kept constant.

Note that the electrolyzed water spraying device D may not have the tank member 15 . In this case, the water supply line for the electrolyzed water spraying device D is pulled from the tap water, and when the water level in the water reservoir 14 drops, the water level in the water reservoir 14 rises to a predetermined position. You may make it supply tap water.

The casing portion 11 has a discharge port 12 on the upper surface side of the main body case 1 of the casing portion 11 and a suction port 13 on the back side of the main body case 1 of the casing portion 11 .

The air volume of the air blower 7 is determined for each air volume unit time (for example, 5 minutes) according to the concentration of carbon dioxide. The amount of rotation of the motor section 9 is controlled based on the determined air volume. One cycle of generating electrolyzed water can be divided into a plurality of air volume unit times.

The filter part 16 is a member that brings the electrolyzed water stored in the water storage part 14 into contact with the indoor air that has flowed into the main body case 1 by the blower part 7 . The filter part 16 is configured in a cylindrical shape, and a filter 16a having holes through which air can flow is arranged in the circumference part. It is rotatably built in the water storage part 14 with the central axis of . The filter part 16 is rotated by a driving part (not shown), and has a structure in which the electrolyzed water and the room air are brought into continuous contact with each other.

The air passage 8 communicates the intake port 2 and the blowout port 6, and includes a filter portion 16, a blower portion 7, and a blowout port 6 in order from the intake port 2. - 特許庁When the fan portion 10 is rotated by the motor portion 9, the external air sucked from the air intake port 2 and entering the air passage 8 passes through the filter 16a, the blower portion 7, and the blowout port 6 in order to the electrolyzed water spraying device D. is blown out of the Thereby, the electrolyzed water generated in the water storage part 14 is sprayed to the outside. The electrolyzed water spraying device D may not necessarily spray the electrolyzed water itself, and even if it sprays the active oxygen species derived from the electrolyzed water generated as a result (including volatilization), the electrolyzed water is sprayed. include.

FIG. 5 is a functional block diagram showing functions of the electrolyzed water spraying device D in blocks. The electrolyzed water spraying device D includes a control unit 30 that controls the entire electrolyzed water spraying device D, such as the electrolyzed water generating unit 5 and the spraying unit 19 . 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 spraying device D also has carbon dioxide calculating means 51 , which is connected to the control section 30 .

The carbon dioxide calculating means 51 is composed of a carbon dioxide detecting means 52 for detecting carbon dioxide and a carbon dioxide estimating means 53 for estimating the concentration of carbon dioxide from the value of the carbon dioxide detecting means 52, and acquires the concentration of carbon dioxide. .

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

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

The generation control unit 34 controls generation of electrolyzed water in the electrolysis unit 17 . Specifically, the energization time for electrolyzing the electrode member of the electrolysis unit 17 and the non-energization time after the energization is stopped are defined as one cycle. Generate electrolyzed water.

The purification capability determination unit 54 determines the generation conditions of the electrolyzed water in the electrolysis unit 17 and the conditions of the blower unit 7 based on the purification capability level determined from the carbon dioxide concentration acquired by the carbon dioxide calculation unit 51 for each air volume unit time. Determine the air volume. Electrolyzed water generation conditions are the energized time and non-energized time in one cycle for generating electrolyzed water, and the amount of electric power during the energized 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 spraying device D based on this.

As shown in FIG. 6, the concentration range of carbon dioxide obtained from the carbon dioxide calculating means 51 is associated with the purification level. In the example of FIG. 6, the purifying ability level is shown in three stages from LV1 to LV3, and is set so that the higher the concentration of carbon dioxide, the higher the purifying ability level. If the amount of ventilation in the room in which the electrolyzed water spraying device D is installed is insufficient, the concentration of carbon dioxide in the room increases due to the carbon dioxide discharged from the breathing of the people in the room.

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

As shown in FIG. 7(a), the purification capacity level and the air volume are associated. In the example of FIG. 7(a), the air volume is shown in three stages from 1, and is set such that the higher the purification capacity level, the larger the air volume. When the air volume increases, the amount of reactive oxygen species contained in the air blown out from the outlet 6 increases, so many viruses can be inactivated.

FIG. 7(b) shows an example of the relationship between the purification capacity level and the amount of electric power, and the purification capacity determination unit 54 determines the amount of electric power for the electrolyzed water spraying device D 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. 7(b), the magnitude of the current (electrode current) flowing through the electrode member is defined as the amount of electric power to be determined. The electrode current is shown in three stages from 1 to 3, and is set such that the higher the purification ability level, the larger the electrode current. By controlling the voltage applied to the electrode member so that the current flowing through the electrode member becomes the determined current, the amount of electric power during the energization time is determined. If the amount of electric power during the energization time is increased, electrolyzed 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 blower outlet 6 also increases, many viruses can be inactivated.

FIG. 7(c) shows an example of the relationship between the purifying capacity level and the energization time, and the purifying capacity determination unit 54 determines the energization time of the electrolyzed water spraying device 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. 7(c), the energization time is shown in three stages from 1 to 3, and the energization time is set to be longer as the purification ability level is higher. When the energization time runs out, electrolyzed 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 blower outlet 6 also increases, many viruses can be inactivated.

FIG. 7(d) 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 spraying device D based on this.

As shown in FIG. 7(d), the purification capacity level and the non-energization time are associated. In the example of FIG. 7(d), the non-energization time is shown in three stages from 1 to 3, and the non-energization time is set to be shorter as the purification ability level is higher. If the non-energization time is shortened, the energization time in one cycle for generating electrolyzed water is lengthened, 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 blower outlet 6 also increases, many viruses can be inactivated.

FIG. 7(e) shows an example of the relationship between the purification capability level, the air volume, and the electrolyzed water generation conditions. to decide.

As shown in FIG. 7(e), the purification capability level is associated with the air volume and the electrolyzed water generation conditions. In the example of FIG. 7(e), as the air volume and the electrolyzed water generation condition to be determined, the energized time and non-energized time in one cycle of generating electrolyzed water, and the electric energy during the energized time are defined. Air volume and electrolyzed water generation conditions are shown in three stages from 1 to 3, and the higher the purification ability level, the more electrolyzed water containing active oxygen species is generated per cycle of electrolyzed water generation. is set to

In addition, in FIG. 7(e), all of FIGS. 7(a) to 7(d) are combined, but a plurality of them may be combined.

A change in the air volume is determined for each air volume unit time (for example, 5 minutes).

The amount of electric power is changed each time the power is being supplied. On the other hand, if it is not energized, it will be changed from the next energization.

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

As for the de-energization time, if de-energization is in progress, the current de-energization time is compared with the changed de-energization time to determine whether to continue de-energization or end de-energization and switch to energization. On the other hand, if it is being energized, it will be changed from the next time it is not energized.

As described above, in the electrolyzed water spraying device D in the first embodiment, based on the value of the carbon dioxide calculation means 51, the energization time to the electrolysis unit 17 in one cycle of generating electrolyzed water, the non-energization time after the energization The energization time, the amount of electric power during the energization time, and the air volume of the air blower 7 are determined.

As a result, an optimum amount of active oxygen species can be generated according to the usage environment of the electrolyzed water spraying device D, and the amount of active oxygen species contained in the air blown out from the blowing port 6 is also increased. Can inactivate viruses.

Further, the electrolyzed water spraying device D of the present embodiment determines the energized time, the non-energized time, and the amount of electric power as conditions for generating electrolyzed water. As a result, if you want to increase the amount of reactive oxygen species contained in electrolyzed water according to the carbon dioxide concentration, you can increase the amount of power by increasing the power supply time, shortening the non-energization time, or increasing the amount of power. , the amount of reactive oxygen species generated can be easily adjusted.

(Second embodiment)
Next, an electrolyzed water spraying device D according to a second embodiment of the present invention will be described with reference to FIGS. The electrolyzed water spraying device D of the first embodiment is based on the value of the carbon dioxide calculation means 51, the energization time to the electrolysis unit 17 in one cycle of generating electrolyzed water, the non-energization time after the energization, and the energization time and the air volume of the air blower 7 were determined. On the other hand, the electrolyzed water spraying device D of the second embodiment, based on the value of the carbon dioxide calculation means 51 and the value of the activity amount determination unit 55, energizes the electrolysis unit 17 in one cycle of generating electrolyzed water. The time, the non-energization time after the energization, the power amount during the energization time, and the air volume of the air blower 7 are determined.

The electrolyzed water spraying device D of the second embodiment will be described below, focusing on the differences from the electrolyzed water spraying device D of the first embodiment. The same components as those of the electrolyzed water spraying device D of the first embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.

FIG. 8 is a functional block diagram showing functions of the electrolyzed water spraying device D of the second embodiment in blocks. The electrolyzed water spraying device D of this embodiment includes a purification capacity determining section 57 instead of the purification capacity determining section 54 of the electrolyzed water spraying device D of the first embodiment. Not only the value of the carbon dioxide calculation means 51 but also the value of the activity amount determination part 55 are input to the purification capacity determination part 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 person detection means 56 .

The purification capacity determination unit 57 determines the purification capacity level determined from the carbon dioxide concentration obtained by the carbon dioxide calculation unit 51 and the amount of human activity obtained by the activity amount determination unit 55 for each air volume unit time. , the conditions for generating electrolyzed water in the electrolyzing unit 17 and the air volume of the air blowing unit 7 are determined.

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

As shown in FIG. 9, the concentration range of carbon dioxide obtained from the carbon dioxide calculator 51 and the amount of activity of a person and the purification level obtained from the activity amount determination unit 55 are associated with each other. In the example of FIG. 6, the amount of activity is shown in two stages, large and small, and the purification capacity level is shown in three stages, LV1 to LV3. Depending on the amount of activity, the carbon dioxide concentration threshold is changed. . It is set so that the greater the amount of activity, the higher the purification capacity level even when the carbon dioxide concentration is low.
That is, the relationship between the threshold position A3 at which the activity amount is "large" and the purification capacity level is LV3 and the threshold position A2 at which the activity amount is "small" and the purification capacity level is LV3 is A3<A2.

The relationship between the purification capability level, the conditions for generating electrolyzed water in the electrolysis unit 17, and the air volume of the blower unit 7 is the same as in the electrolyzed water spraying device D of the first embodiment.

In the room where the electrolyzed water spraying device D is arranged, as the amount of activity of the people in the room increases, the concentration of carbon dioxide discharged from the respiration of the people in the room increases. On the other hand, since the distance between the electrolyzed water spraying device D and the person in the room is long, there is a possibility that a time difference will occur until the carbon dioxide concentration diffuses. Therefore, it is possible to detect that the amount of activity increases and increase the purification capacity level before the carbon dioxide concentration increases.

As described above, in the electrolyzed water spraying device D in the second embodiment, based on the value of the carbon dioxide calculation means 51 and the value of the activity amount determination unit 55, The energization time, the non-energization time after the energization, the power amount during the energization time, and the air volume of the air blower 7 are determined.

As a result, an optimum amount of active oxygen species can be generated according to the usage environment of the electrolyzed water spraying device D, and the amount of active oxygen species contained in the air blown out from the blowing port 6 is also increased. Can inactivate viruses.

Moreover, the electrolyzed water spraying device D of this embodiment uses the relationship between the carbon dioxide concentration, the amount of activity, and the purification capacity level. The resident's activity causes an increase in the resident's respiratory rate and an increase in carbon dioxide concentration. Therefore, by detecting the amount of activity of the resident, the purification ability level can be changed early by the diffusion of carbon dioxide. As a result, an optimum amount of active oxygen species can be generated according to the usage environment of the electrolyzed water spraying device D, and the amount of active oxygen species contained in the air blown out from the blowing port 6 is also increased. Can inactivate viruses.

(Third Embodiment)
Next, with reference to FIG. 10, an electrolyzed water spraying device D, which is a third embodiment of the present invention, will be described. In the electrolyzed water spraying device D of the second embodiment, the conditions for generating electrolyzed water and the air volume of the air blower 7 are determined based on the value of the carbon dioxide calculator 51 and the value of the activity amount determination unit 55 . In contrast, the electrolyzed water spraying device 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 .

The electrolyzed water spraying device D of the third embodiment will be described below, focusing on the differences from the electrolyzed water spraying device D of the second embodiment. The same components as those of the electrolyzed water spraying device D of the second embodiment are denoted by the same reference numerals, and descriptions thereof are omitted.

FIG. 10 is a functional block diagram showing functions of the electrolyzed water spraying device D of the third embodiment. The electrolyzed water spraying device D of this embodiment includes carbon dioxide calculating means 58 instead of the carbon dioxide calculating means 51 of the electrolyzed water spraying device D of the second embodiment. The carbon dioxide calculation means 58 is composed of hydrogen detection means 59 and human emission carbon dioxide estimation means 60 . The human emission carbon dioxide estimation means 60 estimates the carbon dioxide concentration from the value of the hydrogen detection means 59 based on the relationship between the hydrogen concentration and the carbon dioxide concentration in human breath.

As a result, the carbon dioxide concentration can be calculated by the hydrogen detection means instead of the carbon dioxide detection means, the optimum amount of active oxygen species can be generated more inexpensively according to the usage environment of the electrolyzed water spraying device D, and furthermore , the amount of active oxygen species contained in the air blown out from the blower outlet 6 also increases, so many viruses can be inactivated.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above-described embodiments, and it is easily understood that various modifications and improvements are possible without departing from the scope of the present invention. It can be inferred. For example, the numerical values given in each of the above embodiments are examples, and it is naturally possible to employ other numerical values.
