A configuration may be adopted in which the second stop period is set longer than the above.

As a result, the higher the humidity, the higher the purification capacity, the lower the gas-liquid contact amount, and the higher the concentration of active oxygen species without increasing the humidification amount. Therefore, it is possible to properly purify the room while maintaining the desired humidity.

Further, when the amount of air from the air blower is less than a predetermined amount, the purification ability determination unit controls the drive unit so that the entire period of the one cycle is the always-on period regardless of the concentration of the electrolyzed water.

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 electrolytic water spraying device D according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 8. 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 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. FIG. 5 is a cross-sectional view of the electrolyzed water spraying device D cut in the horizontal direction when viewed from the front.

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.

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 . In this case, the electrolyzed water spraying device D may notify the user to insert the electrolysis-enhancing tablet by display or sound, and the user may directly insert the electrolysis-enhancing tablet into the water reservoir 14. .

The tank member 15 is installed on the right side surface of the inside of the main body case 1 when viewed from the front. 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 gas-liquid contact filter portion 16a is rotated by the driving portion 16b, and has a structure in which the electrolyzed water and the room air are brought into continuous contact with each other. Assuming that the amount of air in contact with the electrolyzed water in the gas-liquid contact filter portion 16a per unit time is defined as the gas-liquid contact amount, the greater the gas-liquid contact amount, the higher the purification capability. Although the details will be described later, the electrolyzed water spraying device D detects the gas-liquid contact amount, the energization time to the electrode member, the non-energization time, and the electrode current amount during the energization time by the humidity detection means 51. Determined based on detected values. Accordingly, by controlling the concentration of active oxygen species, the room can be appropriately purified while maintaining the desired humidity.

The water spraying device D is blown out. 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. 6 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 humidity detection means 51 , which is connected to the control section 30 .

The humidity detection means 51 is provided at a place where it is not affected by air containing electrolyzed water (or active oxygen species) blown out from the outlet 6 . Thereby, the humidity 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.

In the table shown in FIG. 7, the purifying ability level is shown in three stages of LV1 to LV3, and when the humidity detected by the humidity detection means 51 is higher than the predetermined humidity of 55%, the purifying ability level is high. set to be Furthermore, in order to reduce the amount of gas-liquid contact in the electrolyzed water spraying device D, the energization control of the drive unit 16b is controlled by ON/OFF control, and the higher the humidity, the longer the stop time of the drive unit 16b. be done. As a result, when the humidity is high, the amount of humidification is reduced by increasing the concentration of active oxygen species generated in the water reservoir 14 and reducing the amount of gas-liquid contact. Therefore, it is possible to improve the purifying ability by increasing the concentration of reactive oxygen species supplied into the room while suppressing an increase in the amount of humidification. Note that ON/OFF control is control that repeats the operation and stop of the driving unit.

Further, when the humidity detected by the humidity detection means 51 is less than the predetermined humidity of 55%, it is not in a state of over-humidification, so it is necessary to reduce the gas-liquid contact amount in the electrolyzed water spraying device D. Therefore, the energization control of the drive unit 16b is always ON.

FIG. 8(a) shows an example of the relationship between the purification capacity level and the electrode current amount, and the purification capacity determination unit 54 determines the electrode current amount of the electrolyzed water spraying device D based on this.

As shown in FIG. 8(a), the purification ability level and the electrode current amount are associated. In the example of FIG. 8A, as the electrode current to be determined, the magnitude of the current (electrode current) flowing through the electrode member is defined. 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 electrode current during the energization time is determined. Electrolyzed water containing a larger amount of active oxygen species is produced by increasing the amount of electrode current during the energization time. 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. 8(b) shows an example of the relationship between the purification capacity level and the energization time, and the energization time of the electrolyzed water spraying device D is determined in the purification capacity determination unit 54 based on this.

As shown in FIG. 8(b), the purification capacity level and the energization time are associated. In the example of FIG. 8(b), 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. As the energization time becomes longer, 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. 8(c) 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. 8(c), the purification capacity level and the non-energization time are associated. In the example of FIG. 8(c), the de-energization time is shown in three stages from 1 to 3, and is set so that the de-energization time becomes 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. 8(d) shows an example of the relationship between the purification capacity level, the air volume, and the electrolyzed water generation conditions. to decide.

As shown in FIG. 8(d), the purification capability level and the electrolyzed water generation conditions are associated. In the example of FIG. 8(d), as the electrolyzed water generation conditions to be determined, the energization time and non-energization time in one cycle for generating electrolyzed water and the electrode current amount during the energization time are defined. The 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. set.

In addition, in FIG. 8(d), all of FIGS. 8(a) to 8(c) are combined, but a plurality of them may be combined.

The electrode current amount is changed each time the current 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 according to the first embodiment, based on the value of the humidity detection means 51, the energization time to the electrolysis unit 17 in one cycle of generating electrolyzed water, the de-energization after the energization Time, the amount of current in the energization time, and the stop time of the drive unit 16b are determined.

As a result, when the humidity is high, the purification capacity of the electrolyzed water spraying device D is increased while the gas-liquid contact amount is decreased, and the concentration of active oxygen species can be increased without increasing the humidification amount. .

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 the electrolyzed water according to the humidity, you can generate The amount of reactive oxygen species released can be easily adjusted.

Further, in the electrolyzed water spraying device D of the present embodiment, as a method of reducing the amount of gas-liquid contact, ON/OFF control is performed on the drive unit 16b. As a result, the gas-liquid contact amount can be adjusted with a simpler configuration than when changing the rotational speed.

As shown in FIGS. 9A and 9B, during the energization time Ton to the electrolysis unit 17, electrolyzed water, that is, active oxygen species is newly generated, so that the electrolyzed water stored in the water storage unit 14 The concentration of reactive oxygen species in the On the other hand, during the non-energization time Toff to the electrolysis unit 17, no new electrolyzed water is generated, and the concentration of the electrolyzed water supplied from the tank 15a and stored in the water storage unit 14 is low by the amount decreased by the gas-liquid contact. Become. During the period when the concentration of reactive oxygen species stored in the water storage unit 14 exceeds the threshold in FIG. 9B, for example, the average value of the concentration of the reactive oxygen species stored in the water storage unit 16b is controlled ON/OFF, and the period during which the concentration of reactive oxygen species is lower than the average value is always ON. Specifically, if the period from the start of energization to the electrolytic part 17 until the threshold value is exceeded is t1, and the period from the end of energization to the electrolytic part 17 until the threshold value is exceeded is t2, the energization to the electrolytic part 17 After t1 of the start, the ON/OFF control of the driving section 16b is started, and after t2 of stopping the supply of electricity to the electrolysis section 17, the ON/OFF control of the driving section 16b is stopped so that the driving section 16b is always ON.

FIG. 10 shows an example of the relationship between the humidity, the energization control of the drive unit, and the purification capacity level. Determine your level of competence.

In the example of FIG. 10, the purifying ability level is shown in three stages from LV1 to LV3, and is set so that the higher the humidity, the higher the purifying ability level. Furthermore, in order to reduce the amount of gas-liquid contact, the energization control of the drive unit 16b is controlled by ON/OFF control, and the stop time of the drive unit 16b is set to be longer as the humidity is higher. As a result, when the humidity is high, the gas-liquid contact amount is decreased while the purification ability is increased, and the concentration of active oxygen species can be increased without increasing the humidification amount.

In the example of FIG. 10, the rotation of the filter portion 16 is set to 6 rotations/minute, that is, 10 seconds/rotation, and the ON time of the ON/OFF control is stopped each time the filter portion 16 makes one rotation. As a result, water retention in the gas-liquid contact filter portion 16a can be ensured, and a sufficient amount of active oxygen species can be dispersed.

As described above, in the electrolyzed water spraying device D in the second embodiment, the energization time to the electrolysis unit 17 in one cycle of generating electrolyzed water and the non-energization time after the energization are determined based on the value of the humidity detection means 51. The time, the electrode current amount in the energization time, and the energization control of the drive unit 16b are determined.

As a result, when the humidity is high, the purification capacity of the electrolyzed water spraying device D is increased, and the gas-liquid contact amount during the period when the concentration of active oxygen species in the electrolyzed water is high is reduced, thereby increasing the humidification amount. without increasing the concentration of reactive oxygen species.

It should be noted that the above control may not be performed when the amount of air blown by the air blower 7 is less than a predetermined value. Specifically, when the air volume is set to high, medium, or low, the above control is not performed only when the air volume is set to low. As a result, when the air volume is set so that the effect of increasing the amount of humidification is small, the energization control of the drive unit 16b is always turned on, and the concentration of reactive oxygen species can be increased.
