(First Embodiment)
First, the electrolyzed water spraying device D according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6. FIG. 1 is a perspective view of the electrolyzed water spraying device D, and is a view of the electrolyzed water spraying device D as viewed from the front side. FIG. 2 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 with the panel 3 of FIG. 1 open.

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 square-shaped intake ports 2 on both side surfaces of the main body case 1. An openable / closable air outlet 6 is provided on the top surface of the main body case 1. In FIGS. 1 and 2, the outlet 6 is in a closed state.

A panel 3 that can be opened and closed is provided on the first main body side surface 1A, which is the right side surface (one side side surface of the main body case 1) when viewed from the front side of the main body case 1. An intake port 2 on one side of the main body case 1 is provided on the panel 3. When the panel 3 is opened, a vertically long square-shaped opening 4 appears. The water storage unit 14, the water supply unit 15, the tablet charging case 18a, and the like, which will be described later, can be taken out from the opening 4.

FIG. 3 is a cross-sectional view of the electrolyzed water spraying device D with the central portion in the front view cut in the vertical direction, and is a view of the electrolyzed water spraying device D viewed from the right side. The air passage configuration and the like created by the electrolyzed water spraying device D are shown. FIG. 4 is a cross-sectional view of the electrolyzed water spraying device D with the right side in the front view cut in the vertical direction, and is a view seen from the right side of the electrolyzed water spraying device D. The peripheral configuration related to the generation of electrolyzed water such as tank members is shown. FIG. 5 is a functional block diagram showing the functions of the electrolyzed water spraying device D in blocks.

As shown in FIGS. 2 to 5, the main body case 1 is provided with an electrolyzed water generating unit 5, a water supply unit 15, a spraying unit 19, and an air passage 8. The electrolyzed water generation unit 5 includes a pair of electrodes 17 and a water storage unit 14.

The water storage unit 14 has a box shape with an open top surface and has a structure capable of storing water. The water storage unit 14 is arranged in the lower part of the main body case 1, slides horizontally from the main body case 1, and can be attached to and detached from the main body case 1, and can be taken out from the opening 4. The water storage unit 14 stores water supplied from the water supply unit 15.

The pair of electrodes 17 are provided with electrode members (not shown), and the electrode members are installed so as to be immersed in water in the water storage unit 14. By energizing the electrode members, the pair of electrodes 17 electrochemically electrolyze the water containing chloride ions in the water storage unit 14 to generate electrolyzed water containing active oxygen species. Here, the active oxygen species are oxygen molecules having higher oxidative activity than ordinary oxygen and related substances. For example, the so-called active oxygen in the narrow sense such as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide includes the so-called broadly defined active oxygen such as ozone and hypochlorous acid (hypochlorous acid).

The pair of electrodes 17 have one cycle of energizing time for electrolyzing the electrode member and non-energizing time, which is the time after the energization is stopped, that is, the non-energizing time. Electrolyzed water is generated by repeating the process multiple times. The life of the electrode member can be extended by providing the electrode member with a non-energized time. If the energization time is lengthened with respect to the non-energization time, electrolyzed water containing a larger amount of active oxygen species is generated per cycle. Further, if the non-energization time is lengthened with respect to the energization time, the generation of active oxygen species per cycle can be suppressed. Further, if the amount of electric power during the energization time is increased, electrolyzed water containing a larger amount of active oxygen species is generated.

The electrolysis-accelerated tablet charging unit 18 includes a tablet charging case 18a, a tablet charging member (not shown) provided in the tablet charging case 18a, and a tablet charging cover 18b detachably provided on the upper part of the tablet charging case 18a. It has. The tablet loading case 18a is configured to be removable from the opening 4. The user can load the electrolysis-accelerated tablet into the tablet loading case 18a by removing the tablet loading cover 18b from the tablet loading case 18a taken out.

The electrolysis-promoting tablet charging unit 18 rotates the tablet charging member when the electrolysis-promoting tablet is charged into the water storage unit 14. When the tablet loading member rotates, the electrolysis-promoting tablet falls into the water storage unit 14 through the drop opening (not shown) on the bottom surface of the tablet loading case 18a. The electrolysis-promoting tablet charging unit 18 counts the number of electrolysis-promoting tablets dropped from the tablet charging case 18a into the water storage unit 14, and determines that one electrolysis-promoting tablet has dropped from the tablet charging case 18a into the water storage unit 14. Stop the rotation of the tablet loading member. When the electrolysis-promoting tablet dissolves in the water in the water storage unit 14, water containing chloride ions is generated in the water in the water storage unit 14. An example of an electrolysis-promoting tablet is sodium chloride.

The electrolyzed water spraying device D does not have to have the electrolysis promoting tablet charging unit 18. In this case, the electrolyzed water spraying device D may display or sound a notification instructing the user to put the electrolyzed water-promoting tablet, and cause the user to directly put the electrolyzed water-promoting tablet into the water storage unit 14. ..

The control unit 30 is provided, for example, on the back side of the operation panel provided on the top surface of the main body case 1 (see FIG. 1), and controls the electrolyzed water spraying device D. The control unit 30 controls the electrolysis of water by the pair of electrodes 17, and also controls the injection of the electrolysis-accelerated tablet by the electrolysis-accelerated tablet charging unit 18. In particular, the control unit 30 determines the injection of the electrolysis-promoting tablet by the electrolysis-promoting tablet charging unit 18 based on the brightness information detected by the illuminance detecting unit 20. The details of the acquisition of brightness information and the control contents by the illuminance detection unit 20 will be described later with reference to FIG.

The water supply unit 15 is installed on the side surface on the right side of the front view inside the main body case 1, has a structure that can be attached to and detached from the water storage unit 14, and can be taken out from the opening 4. The water supply unit 15 is attached to a tank holding unit 14a provided on the bottom surface of the water storage unit 14. The water supply unit 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 portion (not shown) is provided in the center of the lid 15b, and when the opening / closing portion is opened, the water in the tank 15a is supplied to the water storage portion 14.

Specifically, when the tank 15a is attached to the tank holding portion 14a of the water storage portion 14 with the opening of the tank 15a facing downward, the opening / closing portion is opened by the tank holding portion 14a. That is, when water is put into the tank 15a and attached to the tank holding portion 14a, the opening / closing portion is opened to supply water to the water storage portion 14, and the water is collected in the water storage portion 14. When the water level in the water storage unit 14 rises and reaches the lid 15b, the opening of the tank 15a is sealed and the water supply is stopped, water remains inside the tank 15a, and the water level in the water storage unit 14 drops. In each case, the water inside the tank 15a is supplied to the water storage unit 14. That is, the water level in the water storage unit 14 is kept constant.

The electrolyzed water spraying device D does not have to have the tank 15a as the water supply unit 15. In this case, the line for supplying water to the electrolytic water spraying device D is drawn from tap water, and when the water level in the water storage unit 14 drops, until the water level in the water storage unit 14 rises to a predetermined position. Tap water may be supplied.

The spraying unit 19 includes a blowing unit 7 and a filter unit 16. The blower portion 7 is provided in the central portion of the main body case 1, and includes a motor portion 9, a fan portion 10 rotated by the motor portion 9, and a scroll-shaped casing portion 11 surrounding them. The motor portion 9 is fixed to the casing portion 11.

The fan portion 10 is a sirocco fan and is fixed to a rotating shaft 9a extending in the horizontal direction from the motor portion 9, and the motor portion 9 is fixed to the casing portion 11. The rotation shaft 9a of the motor unit 9 extends from the front side to the back side of the main body case 1. The casing portion 11 is provided with a discharge port 12 on the upper surface side of the main body case 1 of the casing portion 11, and has a suction port 13 on the back surface side of the main body case 1 of the casing portion 11.

The air volume of the blower unit 7 is determined based on the air volume set by the user. The amount of rotation of the motor unit 9 is controlled based on the determined air volume.

The filter unit 16 is a member that brings the electrolyzed water stored in the water storage unit 14 into contact with the indoor air that has flowed into the main body case 1 by the blower unit 7. The filter portion 16 is formed in a cylindrical shape, and a filter 16a having a hole through which air can flow is arranged in the circumferential portion, and the filter 16a is arranged so that one end thereof is immersed in the water of the water storage portion 14 to retain water. It is rotatably built in the water storage unit 14 with the central axis of the above as the center of rotation. The filter unit 16 is rotated by a drive unit (not shown) to continuously bring the electrolyzed water and the room air into contact with each other.

The air passage 8 communicates the intake port 2 and the air outlet 6, and includes a filter unit 16, a blower unit 7, and an air outlet 6 in this order from the intake port 2. When the fan unit 10 is rotated by the motor unit 9, the external air sucked from the intake port 2 and entered into the air passage 8 is sequentially passed through the filter 16a, the air blowing unit 7, and the air outlet 6 to the electrolyzed water spraying device D. It is blown out to the outside of. As a result, the electrolyzed water generated in the water storage unit 14 is sprayed to the outside. The electrolyzed water spraying device D does not necessarily have to sprinkle the electrolyzed water itself, and even if it sprays the reactive oxygen species derived from the electrolyzed water (including volatilization) generated as a result, the electrolyzed water is sprayed. include.

A method of determining the addition of the electrolysis-promoting tablet based on the brightness information detected by the illuminance detection unit 20 will be described with reference to FIG.

FIG. 6 is a flowchart for determining the charging of the electrolysis-promoting tablet charging section. The control unit 30 executes the charging determination of the electrolysis promoting tablet charging unit 18 at an experimentally determined time cycle such as time information and the amount of water supplied to the water storage unit 14.

To determine the charging of the electrolysis-accelerated tablet charging unit 18, first, the brightness information output from the illuminance detection unit 20 is acquired at the timing of the electrolysis-promoting tablet charging process (S1). The output value is acquired by using, for example, an A / D converter. The illuminance detection unit 20 changes the output voltage value according to the brightness. By using this output value, it is possible to acquire the brightness information around the electrolyzed water spraying device D. In a specific numerical example, an output of 1 V is obtained according to the ambient brightness. By comparing the brightness information acquired in S1 with the threshold value set based on the predetermined brightness, the brightness around the electrolyzed water spraying device D is determined (S2). The threshold value set based on the brightness is, for example, an experimentally obtained value, and is a threshold value for determining whether or not to add the electrolysis-promoting tablet. In a specific numerical example, a voltage value of 0.5 V is set as a predetermined brightness threshold value. When the brightness is brighter than the predetermined brightness, the electrolyzed water spraying device D is operated by adding the electrolyzed promoting tablets. Further, when the brightness is darker than the predetermined brightness, the user feels uncomfortable at night or the like, so the electrolyzed water spraying device D is operated without adding the electrolyzed promoting tablet (S3). In a specific numerical example, since the ambient brightness is 1 V with respect to 0.5 V set as the threshold value of the predetermined brightness, it is judged that the brightness is brighter than the predetermined brightness, and the electrolysis-promoting tablet is added to electrolyzed water. The spraying device D is operated.

The electrolyzed water spraying device D stores the generated electrolyzed water in the water storage unit 14 and sprays it to the outside. When the brightness information is dark, the electrolyzed water generating unit 5 is not charged with the electrolyzed water-promoting tablet, and when it is determined that the brightness has become brighter, the electrolyzed water-promoting tablet is charged to generate electrolyzed water. Since the electrolyzed water is stored in the water storage unit 14 and sprayed, there is no problem in terms of product function even if the electrolyzed water is not generated in a state where the brightness information is dark. Therefore, it is possible to adjust the request for charging the electrolysis-accelerated tablet and the timing of charging to a timing at which the user does not feel uncomfortable.

The threshold value set based on the predetermined brightness may be an experimentally determined threshold value. This is because the brightness information acquired by the illuminance detection unit 20 changes even if the brightness information of the same ambient environment is the same depending on the mounting position and structure of the illuminance detection unit 20. In addition, the user may be able to set it arbitrarily. In this case, the setting is made using a switch or the like on the operation panel provided on the top surface of the main body case 1.

As described above, in the electrolyzed water spraying device D, the brightness is determined by acquiring the brightness information by the illuminance detecting unit 20 and comparing it with the threshold value set based on the predetermined brightness. Further, when the brightness information is large, the electrolysis accelerating tablet is added, and when the brightness information is small, the electrolysis accelerating tablet is not added. By controlling the injection of the electrolysis-promoting tablet based on the brightness information, it is possible to suppress the generation of sounds and notifications at a timing when the user feels uncomfortable, such as at night.

Although the present invention has been described above based on the embodiments, the present invention is not limited to the above embodiments, and it is easy to make various improvements and modifications within a range that does not deviate from the gist 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 adopt other numerical values.

The electrolyzed water spraying device according to the present invention is useful as an electrolyzed water spraying device for removing (including inactivating) bacteria, fungi, viruses, odors, etc. in the air.
