In this structure, the electrodes may deteriorate if the electrolyzed water stored in the water storage section becomes contaminated due to gas-liquid contact.

[0007] The purpose of this invention is to provide a technique for suppressing electrode degradation.

[0021] Before describing specific embodiments of the present invention, a summary of the embodiments will be provided. This embodiment relates to an electrolyzed water spraying device that generates electrolyzed water based on water and an electrolysis promoter, and then sprays it. Conventional electrolyzed water spraying devices generate chloride-containing water by dissolving an electrolysis promoter in water in a storage compartment, and then electrolyze the chloride-containing water by applying an electric current to the electrodes, thereby generating electrolyzed water containing active oxygen species. Furthermore, the electrolyzed water spraying device continuously contacts the generated electrolyzed water with air drawn in from the outside in the storage compartment, and then sprays the electrolyzed water to the outside by rotating a fan. Therefore, the electrolyzed water in the storage compartment is easily contaminated by contact with air. When the electrolyzed water is contaminated, the electrodes may deteriorate.

[0022] To suppress electrode deterioration, the electrolyzed water spraying device of this embodiment divides the water storage section into two tanks: an electrolysis tank and a humidification tank. The electrolysis tank includes electrodes that electrolyze water containing chloride ions to generate electrolyzed water. The electrolyzed water generated in the electrolysis tank is then supplied to the humidification tank. Furthermore, in the humidification tank, the electrolyzed water supplied from the electrolysis tank is continuously brought into contact with air drawn in from the outside, and the electrolyzed water is sprayed to the outside by the rotation of a fan. With this structure, the electrolyzed water in the electrolysis tank does not come into contact with the air, thus reducing the risk of contamination and suppressing electrode deterioration.

[0023] Hereinafter, the electrolyzed water spraying device 1000 according to an embodiment of the present invention will be described with reference to the accompanying drawings. Figure 1 This indicates the internal structure of the electrolyzed water spraying device 1000.

[0024] The electrolytic water spraying device 1000 includes: a water storage tank 100, a water supply tank 110, a cover 112, a first pump 120, a first water supply pipe 122, a supply port 124, a second pump 130, a second water supply pipe 132, a water shortage float 160, an electrolytic cell 200, an electrode section 210, a third pump 220, a third water supply pipe 222, a metering valve 224, a fourth water supply pipe 226, a full water float 250, a water shortage float 260, a humidification tank 300, a spraying section 310, a full water float 350, a water shortage float 360, a drainage float 370, an electrolysis accelerator input section 400, an input port 404, an electrolysis accelerator 410, and a control section 500. Here, the first pump 120, the first water supply pipe 122, and the supply port 124 are included in the first supply section 128, the second pump 130 and the second water supply pipe 132 are included in the second supply section 138, and the third pump 220, the third water supply pipe 222, the metering valve 224, and the fourth water supply pipe 226 are included in the third supply section 228.

[0025] The following will be explained in the order of (1) basic structure, (2) initial processing, (3) normal processing, and (4) restart processing.

[0026] (1) Basic Structure

[0027] The water storage tank 100 has a box shape with an open top surface and a structure capable of storing water supplied from the water supply tank 110, which will be described later. The water storage tank 100 is, for example, disposed on the lower part of the electrolyzed water spraying device 1000. The water supply tank 110 is a tank that stores water internally and can be detached from the water storage tank 100. A cover 112 is provided at the opening (not shown) of the water supply tank 110, and an opening / closing part (not shown) is provided in the center of the cover 112. When the opening / closing part is opened, water from the water supply tank 110 is supplied to the water storage tank 100.

[0028] Specifically, when the water supply tank 110 is installed in the water storage tank 100 with its opening facing downwards, the opening and closing mechanism is open. That is, when the water supply tank 110 with added water is installed in the water storage tank 100, the opening and closing mechanism is open, water is supplied to the water storage tank 100, and water accumulates in the water storage tank 100. If the water level in the water storage tank 100 rises to the cover 112, the opening of the water supply tank 110 is water-sealed. Thus, water supply stops. Even when water remains inside the water supply tank 110, water is supplied to the water storage tank 100 whenever the water level in the water storage tank 100 drops. As a result, the water level in the water storage tank 100 remains constant.

[0029] A first pump 120 is disposed within a water storage tank 100 and connected to a first water supply pipe 122. When the first pump 120 operates according to an instruction from the control unit 500, it draws water stored in the water storage tank 100 into one end of the first water supply pipe 122. The first water supply pipe 122 is a pipe connecting the water storage tank 100 and the electrolytic cell 200, and has a supply port 124 at the side end of the electrolytic cell 200. The water drawn up by the first pump 120 flows within the first water supply pipe 122 and is supplied to the electrolytic cell 200 through the supply port 124. That is, the first pump 120, the first water supply pipe 122, and the supply port 124 supply water from the water storage tank 100 to the electrolytic cell 200.

[0030] The second pump 130 is disposed within the water storage tank 100 and connected to the second water supply pipe 132. When the second pump 130 operates according to the instruction from the control unit 500, it draws water stored in the water storage tank 100 into the second water supply pipe 132. The second water supply pipe 132 is a pipe connecting the water storage tank 100 and the humidification tank 300. The water drawn up by the second pump 130 flows within the second water supply pipe 132 and is supplied to the humidification tank 300. That is, the second pump 130 and the second water supply pipe 132 supply water from the water storage tank 100 to the humidification tank 300.

[0031] The electrolytic cell 200 has a box shape with an open top surface and is disposed below the supply port 124. The electrolytic cell 200 stores water supplied from the supply port 124. An electrolysis accelerator dispensing unit 400 is disposed parallel to the supply port 124 on the upper side of the electrolytic cell 200. The electrolysis accelerator dispensing unit 400 is capable of dispensing electrolysis accelerator 410. When an instruction to dispense electrolysis accelerator 410 is received from the control unit 500, a tablet dispensing component (not shown) is rotated. As the tablet dispensing component rotates, the electrolysis accelerator 410 falls into the electrolytic cell 200. The electrolysis accelerator dispensing unit 400 counts the number of electrolysis accelerators 410 falling into the electrolytic cell 200, and stops rotating the tablet dispensing component when it is determined that one tablet of electrolysis accelerator 410 has fallen into the electrolytic cell 200. In other words, the electrolysis accelerator dispensing unit 400 dispenses electrolysis accelerator 410 into the electrolytic cell 200. Electrolysis accelerator 410 is dissolved in water within electrolytic cell 200, thereby generating water containing chloride ions in electrolytic cell 200. An example of electrolysis accelerator 410 is sodium chloride, which is formed into an electrolysis accelerator tablet.

[0032] Electrode 210 is immersed in water within electrolytic cell 200. By applying an electric current, electrode 210 electrochemically electrolyzes the chloride-containing water within electrolytic cell 200, generating electrolyzed water containing reactive oxygen species. Here, reactive oxygen species refer to oxygen molecules and related substances that have higher oxidizing activity than ordinary oxygen. For example, reactive oxygen species include not only those in the narrow sense, such as superoxide anions, singlet oxygen, hydroxyl radicals, or hydrogen peroxide, but also those in the broad sense, such as ozone and hypochlorous acid (hypohalic acid).

[0033] Electrode 210 is used to generate electrolyzed water by repeatedly performing one cycle, which consists of the energizing time for electrolysis and the non-energizing time after energization stops. By setting a non-energizing time for electrode 210, the lifespan of electrode 210 is extended. Extending the energizing time compared to the non-energizing time results in the generation of electrolyzed water containing a greater amount of active oxygen species in each cycle. Conversely, extending the non-energizing time compared to the energizing time suppresses the generation of active oxygen species in each cycle. Furthermore, increasing the amount of electricity used during the energizing time generates electrolyzed water containing an even greater amount of active oxygen species. Thus, the electrolyzer 200 can be considered a tank for generating electrolyzed water from water to which the electrolysis promoter 410 is added.

[0034] A third pump 220 is disposed within the electrolytic cell 200 and connected to a third water supply pipe 222. When activated according to an instruction from the control unit 500, the third pump 220 draws electrolyzed water stored in the electrolytic cell 200 into one side of the third water supply pipe 222. The third water supply pipe 222 is connected to a metering valve 224, supplying electrolyzed water from the electrolytic cell 200 into the metering valve 224. The metering valve 224 is a liter with a fixed capacity, storing a fixed volume of electrolyzed water supplied from the third water supply pipe 222. The metering valve 224 is connected to a fourth water supply pipe 226, which extends to one side of the humidification tank 300. The electrolyzed water stored in the metering valve 224 flows within the fourth water supply pipe 226 and is supplied to the humidification tank 300. That is, the third pump 220, the third water supply pipe 222, the metering valve 224, and the fourth water supply pipe 226 supply electrolyzed water from the electrolytic cell 200 to the humidification tank 300.

[0035] The humidification tank 300 has a box shape with an open top surface, allowing water supplied from the water storage tank 100 and electrolyzed water supplied from the electrolysis tank 200 to be mixed. This is equivalent to diluting the electrolyzed water supplied from the electrolysis tank 200 with water supplied from the water storage tank 100. A spray unit 310 is provided in the humidification tank 300.

[0036] The spraying unit 310 includes a fan (not shown) and a filter. The fan, for example, is a Sirocco fan, which rotates under the control of the control unit 500. By rotating the fan, air is drawn into the interior of the electrolyzed water spraying device 1000 through an air intake (not shown) provided in the housing (not shown) of the electrolyzed water spraying device 1000.

[0037] The filter is a component that brings into contact between the electrolyzed water stored in the humidification tank 300 and the indoor air flowing into the electrolyzed water spraying device 1000 via a fan. The filter is cylindrical, with air-permeable holes on its circumference. One end of the filter is immersed in and retained in the electrolyzed water stored in the humidification tank 300, and the filter is rotatably housed within the humidification tank 300 about its central axis. The filter is rotated by a drive unit (not shown), ensuring continuous contact between the electrolyzed water and the indoor air.

[0038] An airflow path is formed from the air intake to the filter, fan, and outlet (not shown). When the fan rotates, outside air drawn in from the air intake and entering the airflow path passes sequentially through the filter, fan, and outlet, and is blown out to the outside of the electrolyzed water spraying device 1000. Thus, the electrolyzed water in the humidification tank 300 is sprayed to the outside. The electrolyzed water spraying device 1000 may not necessarily spray the electrolyzed water itself; even the spraying of the active oxygen species ultimately generated from the electrolyzed water (including volatiles) is included in the electrolyzed water spraying.

[0039] A water shortage float 160 installed in the water storage tank 100, a full water float 250 installed in the electrolysis tank 200, a water shortage float 260 installed in the electrolysis tank 200, a full water float 350 installed in the humidification tank 300, a water shortage float 360 installed in the humidification tank, and a drain float 370 are used to detect the presence of water or electrolyzed water. Here, water and electrolyzed water are sometimes collectively referred to as "water". The water shortage float 160, full water float 250, water shortage float 260, full water float 350, water shortage float 360, and drain float 370 are collectively referred to as "floats". Each float has buoyancy and a magnet (not shown), and the position of the magnet is detected by a detection section (not shown). When water is present up to the float position, the float moves to a predetermined position by buoyancy, and the detection section detects the magnet installed on the float. On the other hand, when there is no water up to the float position, the detection section cannot detect the magnet installed on the float.

[0040] A water shortage float 160 detects the water shortage in the water storage tank 100, a full water float 250 detects the fullness of the electrolytic cell 200, and a water shortage float 260 detects the water shortage in the electrolytic cell 200. Here, water shortage may not be 100% water shortage, but may mean very little water remains. In this embodiment, the water shortage float 260 can also be called a water shortage detection unit. Additionally, a full water float 350 detects the fullness of the humidification tank 300, a water shortage float 360 detects the water shortage in the humidification tank 300, and a drainage float 370 detects the drainage level of the humidification tank 300. Here, full water may not be 100% full, but may mean the amount of water that can be further added. Each float sends its detection results to the control unit 500.

[0041] The control unit 500 receives detection results from the water shortage float 160, the full water float 250, the water shortage float 260, the full water float 350, the water shortage float 360, and the drainage float 370. Additionally, the control unit 500 controls the electrode unit 210, the spraying unit 310, the electrolysis promoter addition unit 400, the first supply unit 128, the second supply unit 138, and the third supply unit 228. Details of the processing by the control unit 500 will be described later.

[0042] As an example, the concentration of the electrolyzed water generated in electrolyzer 200 is in the range of 30 to 200 ppm (hereinafter referred to as "first concentration"). Furthermore, the concentration of the electrolyzed water diluted in humidification tank 300 is in the range of 3 to 50 ppm. The concentration of the electrolyzed water diluted in humidification tank 300 is set lower than the concentration of the electrolyzed water generated in electrolyzer 200.

[0043] (2) Initial processing

[0044] The initial treatment involves spraying water from a water-deficient state (specifically, a state without water) in the water storage tank 100, electrolysis tank 200, and humidification tank 300, to the initial stage of water electrolysis. Hereinafter, for the purpose of explaining the initial treatment, we will also use... Figures 2A to 2C , Figure 3A and Figure 3B . Figures 2A to 2C This section describes the operation summary of the electrolytic water spraying device 1000.

[0045] Figure 2A This indicates a water shortage state where the water in the water storage tank 100, electrolysis tank 200, and humidification tank 300 is insufficient. This is equivalent to the situation after purchasing and installing the electrolyzed water spraying device 1000. It also corresponds to the situation after maintaining the water storage tank 100, electrolysis tank 200, and humidification tank 300.

[0046] Figure 2B It continues Figure 2A The user fills water into the water supply tank 110 and installs the water supply tank 110 into the water storage tank 100. When the water supply tank 110 is installed into the water storage tank 100, the opening and closing part of the cover 112 is opened, and water is supplied from the water supply tank 110 into the water storage tank 100.

[0047] Figure 2C It continues Figure 2B The control unit 500 supplies water from the water storage tank 100 to the humidification tank 300 by activating the second pump 130. The water supply continues until the full-water float 350 detects that the tank is full. As a result, the humidification tank 300 stores water in a full-water state.

[0048] The control unit 500 supplies water from the storage tank 100 into the electrolytic cell 200 by activating the first pump 120. During this time, water is supplied to the electrolytic cell 200 for a certain period of time while it is not yet full. As a result of the water supply, the water level in the electrolytic cell 200 is lower than the full water level. A supply area 240 is positioned on a portion of the water surface in the electrolytic cell 200, located below the supply port 124 and the inlet port 404. After the water supply is completed, the control unit 500 injects an electrolysis promoter 410 into the supply area 240 of the electrolytic cell 200 through the inlet port 404. As a result, the electrolysis promoter 410, present in the supply area 240, begins to dissolve in the water.

[0049] Next, the control unit 500 restarts the first pump 120 to supply water from the storage tank 100 into the electrolytic cell 200. At this time, because water is supplied from the supply port 124 to the supply area 240, the dissolution of the electrolysis promoter 410 is further facilitated by the pressure of the supplied water. Water supply continues until the full-water float 250 detects that the tank is full. As a result, the humidification tank 300 stores water containing chloride ions, a portion of the dissolved electrolysis promoter 410, in a full-water state.

[0050] Figure 3A and Figure 3B Indicates the following Figures 2A to 2C Summary of the operation of the electrolytic water spraying device 1000.

[0051] Figure 3A It continues Figure 2C The control unit 500 electrolyzes water containing chloride ions by energizing the electrode unit 210 to generate electrolyzed water. Here, the electrolysis time is set to be shorter than the time required to generate electrolyzed water of the first concentration (e.g., 40 minutes). As a result, electrolyzed water of the second concentration, lower than the first concentration, is generated.

[0052] Figure 3B It continues Figure 3A The state is as follows. When electrolyzed water of the second concentration is generated, the control unit 500 supplies the electrolyzed water of the second concentration to the humidification tank 300 by activating the third pump 220. At this time, because a metering valve 224 is used, only the capacity of the metering valve 224 of the electrolyzed water of the second concentration is supplied to the humidification tank 300. The electrolyzed water of the second concentration is diluted in the humidification tank 300. After the control unit 500 stops the third pump 220, it activates the spraying unit 310, thereby spraying the electrolyzed water in the humidification tank 300 to the outside of the electrolyzed water spraying device 1000. That is, the spraying of electrolyzed water begins from a time period of less than 40 minutes.

[0053] (3) Normal processing

[0054] The typical treatment is used to spray electrolyzed water at the desired concentration. Figure 4A and Figure 4B Indicates the following Figure 3A and Figure 3B Summary of the operation of the electrolytic water spraying device 1000.

[0055] Figure 4A It continues Figure 3B The state is such that, because a portion of the second concentration of electrolyzed water in the electrolyzer 200 is supplied to the humidification tank 300, the second concentration of electrolyzed water is stored in the electrolyzer 200 in a state that is not full. The control unit 500 supplies water from the storage tank 100 to the electrolyzer 200 by activating the first pump 120. At this time, because water is supplied from the supply port 124 to the supply area 240, the remaining electrolysis promoter 410 is further dissolved by the pressure of the supplied water. The water supply continues until the full-water float 250 detects that the water is full. As a result, the humidification tank 300 becomes full. After the water supply to the electrolyzer 200 is completed, the control unit 500 generates electrolyzed water by energizing the electrode unit 210. Here, the electrolysis time is set to the time required to generate the first concentration of electrolyzed water (for example, 40 minutes). As a result, the first concentration of electrolyzed water is generated.

[0056] Figure 4B It continues Figure 4A The state is as follows: When electrolyzed water of the first concentration is generated, the control unit 500 supplies electrolyzed water of the first concentration into the humidification tank 300 by activating the third pump 220. At this time, because a metering valve 224 is used, only the capacity of the metering valve 224 of the first concentration of electrolyzed water is supplied to the humidification tank 300. The first concentration of electrolyzed water is diluted in the humidification tank 300. After the control unit 500 stops the third pump 220, it activates the spraying unit 310, thereby spraying the electrolyzed water in the humidification tank 300 to the outside of the electrolyzed water spraying device 1000.

[0057] When electrolyzed water is sprayed, the amount of electrolyzed water in the humidification tank 300 decreases. If the water shortage float 360 detects a water shortage, the control unit 500 activates the third pump 220 to supply electrolyzed water of the first concentration to the humidification tank 300 at the amount specified by the metering valve 224, and activates the second pump 130 to supply water from the water storage tank 100 to the humidification tank 300 until it is full. Thus, the spraying of electrolyzed water continues. This process is repeated until the water shortage float 260 detects a water shortage.

[0058] (4) Restart the process

[0059] Restart processing is a process used to perform normal processing again when the water shortage float 260 detects a water shortage, i.e., when the electrolyzed water in the electrolyzer 200 is insufficient. After supplying electrolyzed water of the first concentration to the humidification tank 300, when the water shortage float 260 detects a water shortage, the control unit 500 starts supplying water to the electrolyzer 200 using the first supply unit 128. That is, the control unit 500 does not supply water to the electrolyzer 200 until the electrolyzer 200 is insufficient. This is because by not supplying water, the concentration of the electrolyzed water in the electrolyzer 200 is maintained at the first concentration. In addition, this is because the original electrolyzed water is less likely to remain in the electrolyzer 200, and impurities such as inorganic salt compounds are less likely to remain in the electrolyzer 200. As a result, the maintenance frequency of the electrolyzer 200 is reduced.

[0060] Here, similar to the initial treatment, the control unit 500 supplies water for a certain period of time while the electrolyzer 200 is not yet full. Next, the control unit 500 adds an electrolysis promoter 410 to the supply area 240 of the electrolyzer 200 through the inlet 404, and continues supplying water until the electrolyzer 200 is full. Furthermore, the control unit 500 generates electrolyzed water of a second concentration by energizing the electrode 210, and then supplies this second-concentration electrolyzed water from the electrolyzer 200 to the humidification tank 300. That is, a portion of the treatment is performed similarly to the initial treatment. Then, normal treatment is performed.

[0061] (Modified Example)

[0062] When performing the restart process, unlike when performing the initial process, electrolyzed water is present in the humidification tank 300. Therefore, the process of generating electrolyzed water of a second concentration and supplying it from the electrolysis tank 200 to the humidification tank 300 can be omitted. This variation will be described below.

[0063] The control unit 500 supplies water for a certain period of time while the electrolyzer 200 is not yet full. Next, the control unit 500 adds an electrolysis promoter 410 to the supply area 240 of the electrolyzer 200 through the inlet 404. Then, the control unit 500 remains idle for a certain period. This idle period can be shorter or longer than the 10-minute electrolysis time in the initial treatment. Then, the control unit 500 supplies water until the electrolyzer 200 is full. Next, normal treatment is performed. That is, electrolyzed water of a first concentration is generated through electrolysis, but electrolyzed water of a second concentration is not generated.

[0064] The main body of the apparatus, system, or method of this invention includes a computer. The main functions of the apparatus, system, or method of this invention are realized by executing a program on the computer. The computer uses a processor that operates according to the program as its main hardware structure. The type of processor is not limited as long as it can realize its function by executing the program. The processor consists of a semiconductor integrated circuit (IC) or one or more electronic circuits including LSI (Large Scale Integration). Multiple electronic circuits can be integrated on a single chip or disposed on multiple chips. Multiple chips can be concentrated in one device or disposed in multiple devices. The program is recorded in a non-temporary recording medium such as a computer-readable ROM (Read Only Memory), optical disc, or hard disk drive. The program can be pre-stored in the recording medium or provided to the recording medium via a wide area communication network, including the Internet.

[0065] Explain the operation of the electrolyzed water spraying device 1000 with the above structure. Figure 5 This is a flowchart illustrating the control steps of the electrolyzed water spraying device 1000. Furthermore, the following controls can also be performed by the control unit 500.

[0066] First, water is supplied to the water storage tank 100 (S10).

[0067] Next, a smaller amount of water than the full volume is supplied from the water storage tank 100 to the electrolytic cell 200 (S12).

[0068] Next, electrolysis promoter 410 is supplied to electrolytic cell 200 (S14).

[0069] Next, water is supplied from the water storage tank 100 to the electrolytic cell 200 until it is full (S16).

[0070] Next, the electrode section 210 performs electrolysis for 10 minutes (S18).

[0071] Next, electrolyzed water of a second concentration is supplied from the electrolyzer 200 to the humidification tank 300 (S20). At this time, electrolyzed water is sprayed in the humidification tank 300.

[0072] Next, water is supplied from the water storage tank 100 to the electrolytic cell 200 until it is full (S22).

[0073] Next, the electrode section 210 performs electrolysis for 40 minutes (S24).

[0074] Next, electrolyzed water of the first concentration is supplied from the electrolyzer 200 to the humidification tank 300 (S26).

[0075] Next, the spraying section 310 sprays electrolyzed water (S28).

[0076] Next, it is determined whether the humidification tank 300 is short of water using the water shortage float 360 (S30). If it is determined that the humidification tank 300 is not short of water (S30 "No"), the process returns to step S28. On the other hand, if it is determined that the humidification tank 300 is short of water (S30 "Yes"), it is determined whether the electrolytic cell 200 is short of water using the water shortage float 260 (S32). If it is determined that the electrolytic cell 200 is not short of water (S32 "No"), the process returns to step S26. On the other hand, if it is determined that the electrolytic cell 200 is short of water (S32 "Yes"), the process returns to step S12.

[0077] Figure 6 This is a flowchart illustrating the control steps of a modified example of an electrolyzed water spraying device 1000. Furthermore, the following controls can also be performed by the control unit 500.

[0078] First, water is supplied to the water storage tank 100 (S100).

[0079] Next, a smaller amount of water than the full volume is supplied from the water storage tank 100 to the electrolytic cell 200 (S102).

[0080] Next, electrolysis promoter 410 (S104) is supplied to electrolytic cell 200.

[0081] Next, water is supplied from the water storage tank 100 to the electrolytic cell 200 until it is full (S106).

[0082] Next, the electrode section 210 performs electrolysis for 10 minutes (S108).

[0083] Next, electrolyzed water of a second concentration is supplied from the electrolyzer 200 to the humidification tank 300 (S110). At this time, electrolyzed water is sprayed in the humidification tank 300.

[0084] Next, water is supplied from the water storage tank 100 to the electrolytic cell 200 until it is full (S112).

[0085] Next, the electrode section 210 performs electrolysis for 40 minutes (S114).

[0086] Next, electrolyzed water of the first concentration is transferred from the electrolytic cell 200 to the humidification tank 300 (S116).

[0087] Next, the spraying section 310 sprays electrolyzed water (S118).

[0088] Next, it is determined whether the humidification tank 300 is short of water using the water shortage float 360 (S120). If it is determined that the humidification tank 300 is not short of water (S120 "No"), the process returns to step S118. On the other hand, if it is determined that the humidification tank 300 is short of water (S120 "Yes"), it is determined whether the electrolysis tank 200 is short of water using the water shortage float 260 (S122). If it is determined that the electrolysis tank 200 is not short of water (S122 "No"), the process returns to step S116. On the other hand, if it is determined that the electrolysis tank 200 is short of water (S122 "Yes"), a small amount of water (less than full) is supplied from the water storage tank 100 to the electrolysis tank 200 (S124). Then, the electrolysis promoter 410 is supplied to the electrolysis tank 200 (S126), and the process is paused for 10 minutes (S128). Then, water is supplied from the water storage tank 100 to the electrolysis cell 200 until it is full (S130), and the process returns to step S114.

[0089] According to the electrolyzed water spraying apparatus 1000 of this embodiment, since the water storage section is divided into a water storage tank 100, an electrolysis tank 200, and a humidification tank 300, the occurrence of gas-liquid contact between the electrode section 210 and the water in the electrolysis tank 200 can be suppressed. Furthermore, because the occurrence of gas-liquid contact with the water in the electrolysis tank 200 is suppressed, the water in the electrolysis tank 200 is less likely to be contaminated. Additionally, because the water in the electrolysis tank 200 is less likely to be contaminated, electrode degradation can be suppressed. Furthermore, since a second concentration of electrolyzed water is supplied to the humidification tank 300 and sprayed, the time until the electrolyzed water is sprayed can be shortened. Furthermore, since a first concentration of electrolyzed water is generated from the second concentration of electrolyzed water, electrolyzed water of a desired concentration can be sprayed. Furthermore, since an electrolysis promoter 410 is added to the supply area 240 and water is supplied to the supply area 240, the electrolysis promoter 410 can be dissolved by water pressure. In addition, since the first concentration of electrolyzed water is generated through normal treatment after water is supplied to the electrolyzer 200, the electrolysis promoter 410 can be easily dissolved.

[0090] Furthermore, when a water shortage is detected, water is supplied to the electrolyzer 200 via the first supply unit 128, so no water supply is required until a water shortage is detected. Also, because no water supply is required before a water shortage is detected, the concentration of the electrolyzed water in the electrolyzer 200 can be maintained. Furthermore, because no water supply is required before a water shortage is detected, impurities remaining in the electrolyzer 200 can be allowed to flow out. Since the initial treatment is performed as part of the restart process, the operation is simplified. Because a second concentration of electrolyzed water is not generated during the restart process, the first concentration of electrolyzed water can be effectively generated.

[0091] An outline of one aspect of the present invention is shown below. The electrolyzed water spraying device (1000) of the present invention includes: a water storage tank (100) for storing water; an electrolytic cell (200) for generating electrolyzed water from water in which an electrolysis promoter (410) has been added; a first supply unit (128) for supplying water from the water storage tank (100) to the electrolytic cell (200); an electrode unit (210) for generating electrolyzed water in the electrolytic cell (200); a humidification tank (300) for mixing water supplied from the water storage tank (100) and electrolyzed water supplied from the electrolytic cell (200); and a humidification tank (300) for mixing water supplied from the water storage tank (100) and electrolyzed water supplied from the electrolytic cell (200); 00) A second supply unit (138) that supplies water to the humidification tank (300); a third supply unit (228) that supplies electrolyzed water from the electrolytic cell (200) to the humidification tank (300); a spraying unit (310) that brings the electrolyzed water in the humidification tank (300) into contact with air drawn in from the air inlet and sprays it from the air outlet; and a control unit (500) that performs the control of the electrode unit (210), the spraying unit (310), the first supply unit (128), the second supply unit (138), and the third supply unit (228).

[0092] When the water in the electrolyzer (200) is insufficient, the control unit (500) performs an initial treatment to generate electrolyzed water of a second concentration lower than the first concentration and to supply the electrolyzed water of the second concentration to the humidification tank (300) by means of a third supply unit (228) while supplying water and an electrolysis promoter (410) to the electrolyzer (200). After the initial treatment, the control unit (500) performs a normal treatment to generate electrolyzed water of the first concentration and to supply the electrolyzed water of the first concentration to the humidification tank (300) by means of a third supply unit (228).

[0093] Additionally, the electrolyzed water spraying device (1000) of the present invention may also include an electrolysis accelerator injection unit (400) for injecting an electrolysis accelerator (410) into the electrolyzer (200). The first supply unit (128) may also supply water from the water storage tank (100) to the electrolyzer (200) toward the supply area (240) which constitutes part of the water surface of the electrolyzer (200), and the electrolysis accelerator injection unit (400) injects the electrolysis accelerator (410) into the supply area (240).

[0094] Alternatively, the control unit (500) of the present invention can also generate electrolyzed water of the first concentration by supplying water to the electrolyzer (200) through the first supply unit (128) after performing the initial treatment.

[0095] In addition, the electrolyzed water spraying device (1000) of the present invention may also include a water shortage detection unit (260) for detecting water shortage in the electrolyzer (200). The control unit (500) may also supply water to the electrolyzer (200) using the first supply unit (128) when water shortage is detected by the water shortage detection unit (260) after supplying electrolyzed water of the first concentration to the humidification tank (300).

[0096] In addition, the control unit (500) of the present invention can also perform a restart process and perform a normal process after the restart process. In the restart process, water is supplied to the electrolyzer (200) by the first supply unit (128), and an electrolysis promoter (410) is supplied to the electrolyzer (200) to generate electrolyzed water of the second concentration. The electrolyzed water of the second concentration is supplied to the humidification tank (300) by the third supply unit (228).

[0097] In addition, the control unit (500) of the present invention can also perform a restart process, and perform a normal process after the restart process. In the restart process, a certain amount of water is supplied to the electrolytic cell (200) by the first supply unit (128), and after the electrolysis promoter (410) is supplied to the electrolytic cell (200), it stands for a certain period of time, and then water is supplied to the electrolytic cell (200) by the first supply unit (128).

[0098] The present invention has been described above based on embodiments. Those skilled in the art should understand that these embodiments are exemplary, and various modifications can be made to the combination of these constituent elements or processing techniques; such modifications are also within the scope of the present invention.

[0099] In this embodiment, the water shortage float 260 detects water shortage based on the position of the magnet in the float. However, it is not limited to this; for example, water shortage can also be detected based on the number of times water is supplied using the metering valve 224. For example, if the electrolytic cell 200 has a capacity of 1000 ml and the metering valve 224 has a capacity of 250 ml, water shortage is detected after supplying water four times using the metering valve 224. According to this modified example, the degree of freedom of the structure can be increased.

[0100] In this embodiment, water or electrolyzed water is supplied when a water shortage is detected. However, it is not limited to this; for example, water or electrolyzed water may be supplied, and then the next supply may be made after a certain period of time. According to this variation, the degree of freedom of the structure can be increased.

[0101] Additionally, the control unit 500 may include a storage unit for storing currently executed control content. An example of the storage unit is a non-volatile memory. The control unit 500 periodically stores the currently executed control content in the storage unit as needed. When the power to the electrolyzed water spraying device 1000 is interrupted and then restored, the control unit 500 restarts from the executed control content stored in the storage unit. For example, if the control content stored in the storage unit when the power to the electrolyzed water spraying device 1000 is interrupted is the content of performing 5 minutes of electrolysis in step S18 for generating electrolyzed water of the second concentration, then upon power restoration, the control unit 500 performs the following control: performs the remaining 5 minutes of electrolysis required to generate electrolyzed water of the second concentration. Furthermore, for example, if the control content stored in the storage unit when the power to the electrolyzed water spraying device 1000 is interrupted is step S28 for spraying electrolyzed water, then upon power restoration, the control unit 500 restarts the electrolyzed water spraying step. Therefore, even if the power supply to the electrolyzed water spraying device 1000 is cut off and then restored, correct control can still be performed.
