Description

Technical Field

[0001] This disclosure relates to space purification devices. Background Technology

[0002] Space purification devices are known that generate and release electrolyzed water containing hypochlorous acid by electrolysis to remove (including deactivate) bacteria, fungi, viruses, odors, etc. from the air (for example, see Patent Document 1). The generation of hypochlorous acid requires the addition of an electrolysis promoter such as salt to the water to be electrolyzed, so as to pre-generate water containing chloride ions.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2019-24811 Summary of the Invention

[0006] When automatically adding an electrolysis accelerator in a space purification device, a function to detect the addition of the electrolysis accelerator is required. For example, a light-emitting unit and a light-receiving unit that receives light from the light-emitting unit are configured across the electrolysis accelerator addition path. The addition of the electrolysis accelerator is detected when the light level received by the light-receiving unit decreases. In such a structure, if the addition of the electrolysis accelerator is indicated but not detected, the addition of the electrolysis accelerator is indicated again. However, if the addition of the electrolysis accelerator is actually added but the addition detection fails, the electrolysis accelerator is added again. As a result, there is concern that the concentration of hypochlorous acid in the electrolyzed water may become higher than the reference value.

[0007] The purpose of this disclosure is to provide a technique for preventing the concentration of hypochlorous acid in electrolyzed water from becoming higher than a reference value.

[0008] One aspect of the space purification device disclosed herein includes: an electrolytic cell for storing water and electrolyzing water; an electrolysis accelerator injection unit for injecting an electrolysis accelerator into the electrolytic cell; an electrolyzed water generation unit for electrolyzing the water containing the electrolysis accelerator to generate electrolyzed water; a purification unit for contacting the electrolyzed water generated by the electrolyzed water generation unit with air drawn in from an air intake; an injection indicator unit for indicating the injection of the electrolysis accelerator into the electrolysis accelerator injection unit; an injection detection unit for detecting the injection of the electrolysis accelerator by the electrolysis accelerator injection unit; a non-injection detection count unit for counting the number of non-injection detections, wherein the non-injection detection count is the number of times the injection indicator unit indicates the injection of the electrolysis accelerator, but the injection detection unit does not detect the injection of the electrolysis accelerator; and an energizing setting determination unit for determining the energizing setting for electrolysis in the electrolyzed water generation unit based on the number of non-injection detections counted by the non-injection detection count unit.

[0009] Furthermore, any combination of the above-mentioned constituent elements, and any invention obtained by transforming the description of this disclosure among methods, apparatus, systems, recording media, computer programs, etc., are also valid as solutions of this disclosure.

[0010] According to this disclosure, it is possible to prevent the concentration of hypochlorous acid in electrolyzed water from becoming higher than the reference value. Attached Figure Description

[0025] Before detailing the embodiments of this disclosure, a general overview of the embodiments will be provided. This embodiment relates to a space purification device that releases electrolyzed water generated based on water and an electrolysis accelerator. In the space purification device, if the addition of an electrolysis accelerator is indicated but not detected, the addition of the electrolysis accelerator is indicated again. For example, if the electrolysis accelerator is actually added but the addition detection fails, the electrolysis accelerator is re-added. As a result, although only one tablet of electrolysis accelerator should be added to the water, two or more tablets of electrolysis accelerator are added. In this case, when the water containing the electrolysis accelerator is electrolyzed, electrolyzed water with a hypochlorous acid concentration higher than the reference value is generated. Because it is undesirable to release electrolyzed water with a hypochlorous acid concentration higher than the reference value, it is desirable to suppress the concentration of hypochlorous acid in the electrolyzed water from becoming higher than the reference value, even when the addition of the electrolysis accelerator is indicated again.

[0026] The space purification device of this embodiment counts the number of times (hereinafter referred to as "non-input detection counts") that the addition of an electrolysis promoter is indicated but not detected, even though the probability of such an occurrence is low. Then, the space purification device adjusts the energizing time for electrolysis based on the number of non-input detections when the addition is detected. For example, the higher the number of non-input detections, the shorter the energizing time. In this way, even if a large amount of electrolysis promoter is added, the excessive increase in the concentration of hypochlorous acid in the electrolyzed water is suppressed because the energizing time is shorter.

[0027] Furthermore, existing air purification devices generate chloride-containing water by dissolving an electrolysis promoter in the water within a storage compartment. This chloride-containing water is then electrolyzed by applying electricity to electrodes, producing electrolyzed water containing reactive oxygen species. Next, these devices continuously contact the generated electrolyzed water with air drawn in from the outside within the storage compartment, and then release the air to the outside via a rotating fan. Therefore, the electrolyzed water in the storage compartment is easily contaminated by contact with air. If the electrolyzed water becomes contaminated, there is a concern about electrode degradation.

[0028] To suppress electrode deterioration, the space purification device of this embodiment divides the water storage section into two tanks: an electrolysis tank and a humidification tank. The electrolysis tank contains 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. In the humidification tank, the electrolyzed water from the electrolysis tank is continuously brought into contact with air drawn in from the outside, and then the contacted air is released to the outside by a rotating fan. With this structure, the electrolyzed water in the electrolysis tank does not come into contact with the air and is therefore less prone to contamination, thus suppressing electrode deterioration.

[0029] The following description, with reference to the accompanying drawings, illustrates the methods used to implement this disclosure. Figure 1 This indicates the internal structure of the space purification device 1000.

[0030] The space purification 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 buoy 160, an electrolytic cell 200, an electrode section 210, a third pump 220, a third water supply pipe 222, a metering cylinder 224, a third water supply pipe 226, a full water buoy 250, a water shortage buoy 260, a humidification tank 300, a purification section 310, a full water buoy 350, a water shortage buoy 360, a drainage buoy 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, and the second pump 130 and the second water supply pipe 132 are included in the second supply section 138. The third pump 220, the third water supply pipe 222, the metering cylinder 224, and the third water supply pipe 226 are included in the third supply section 228. In addition, the operation of each component of the space purification device 1000 controlled by the control unit 500 is referred to as the operation of the space purification device 1000 controlled by the control unit 500. In the following description, the basic structure, initial treatment, normal treatment, restart treatment, and electrolysis accelerator addition treatment will be described in the following order.

[0031] (1) Basic Structure

[0032] 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 (described later). The water storage tank 100 is, for example, disposed on the lower part of the space purification 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 open, water in the water supply tank 110 is supplied to the water storage tank 100.

[0033] 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, filled with water, is installed in the water storage tank 100, the opening and closing mechanism is open to supply water to the water storage tank 100, and water accumulates inside the water storage tank 100. When 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, and thus the water supply stops. When there is still water remaining inside the water supply tank 110, whenever the water level in the water storage tank 100 drops, water from the water supply tank 110 is supplied to the water storage tank 100. As a result, the water level in the water storage tank 100 is maintained at a constant level.

[0034] A first pump 120 is disposed within a water storage tank 100 and connected to a first water supply pipe 122. When operated according to an instruction from the control unit 500, the first pump 120 draws water stored in the water storage tank 100 into 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 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.

[0035] A second pump 130 is disposed within a water storage tank 100 and connected to a second water supply pipe 132. When operated according to instructions from the control unit 500, the second pump 130 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 by the second pump 130 flows within the second water supply pipe 132 and is supplied to the humidification tank 300. In other words, the second pump 130 and the second water supply pipe 132 supply water from the water storage tank 100 to the humidification tank 300.

[0036] The electrolytic cell 200 has a box shape with an open top surface and is positioned below the supply port 124. The electrolytic cell 200 stores water supplied from the supply port 124. An electrolysis accelerator dispensing unit 400 is arranged parallel to the supply port 124 on the upper side of the electrolytic cell 200. The electrolysis accelerator dispensing unit 400 is capable of being filled with 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 accelerator 410s falling into the electrolytic cell 200, and stops rotating the tablet dispensing component when it determines 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 chloride-containing water in electrolytic cell 200. An example of electrolysis accelerator 410 is sodium chloride, which is formed as an electrolysis accelerator tablet.

[0037] The electrode section 210 is installed with water immersed in the electrolytic cell 200. The electrode section 210 electrochemically electrolyzes the chloride-containing water in the electrolytic cell 200 by passing an electric current through it, generating electrolyzed water containing active oxygen species. Here, active oxygen species refer to oxygen molecules and their associated substances that have higher oxidizing activity than ordinary oxygen. For example, active oxygen species include not only so-called narrowly defined active oxygen species such as superoxide anions, singlet oxygen, hydroxyl radicals, or hydrogen peroxide, but also so-called broadly defined active oxygen species such as ozone and hypochlorous acid (hypohalic acid).

[0038] Electrode 210 can generate electrolyzed water by taking the energizing time for electrolysis and the time after energizing stops (i.e., the non-energizing time) as a cycle and repeating this cycle multiple times. By setting a non-energizing time for electrode 210, the lifespan of electrode 210 is extended. When the energizing time is extended relative to the non-energizing time, electrolyzed water containing a larger amount of active oxygen species is generated in each cycle. Furthermore, when the non-energizing time is extended relative to the energizing time, the generation of active oxygen species in each cycle is suppressed. Furthermore, when the amount of electricity used during the energizing time is increased, electrolyzed water containing a larger amount of active oxygen species is generated. In this way, the electrolytic cell 200 can also be described as a tank for generating electrolyzed water from water to which the electrolysis promoter 410 is added.

[0039] A third pump 220 is disposed within the electrolytic cell 200 and connected to a third water supply pipe 222. When operated according to an instruction from the control unit 500, the third pump 220 draws electrolyzed water stored in the electrolytic cell 200 into the third water supply pipe 222. The third water supply pipe 222 is connected to a metering cylinder 224, supplying electrolyzed water from the electrolytic cell 200 to the metering cylinder 224. The metering cylinder 224 is a cylinder with a fixed capacity, storing a fixed volume of electrolyzed water supplied from the third water supply pipe 222. The metering cylinder 224 is connected to a third water supply pipe 226, which extends to the humidification tank 300. The electrolyzed water stored in the metering cylinder 224 flows within the third 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 cylinder 224, and the third water supply pipe 226 supply electrolyzed water from the electrolytic cell 200 to the humidification tank 300.

[0040] The humidification tank 300 has a box shape with an open top surface, allowing water supplied from the water storage tank 100 to be mixed with electrolyzed water supplied from the electrolysis tank 200. This is equivalent to diluting the electrolyzed water supplied from the electrolysis tank 200 with water supplied from the water storage tank 100. A purification unit 310 is provided in the humidification tank 300.

[0041] The purification unit 310 includes a fan (not shown) and a filter. The fan, for example a Sirocco fan, rotates under the control of the control unit 500. By rotating the fan, air is drawn into the interior of the space purification device 1000 through an air intake (not shown) provided in the outer casing (not shown) of the space purification device 1000.

[0042] 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 space purification device 1000 via a fan. The filter is cylindrical, with air-permeable holes in its circumferential portion. The filter is rotatably housed within the humidification tank 300, with one end immersed in the electrolyzed water stored in the humidification tank 300 and maintaining the electrolyzed water level. The filter rotates via a drive unit (not shown), ensuring continuous contact between the electrolyzed water and the indoor air.

[0043] An airflow path is formed, continuously extending from the intake port to the filter, fan, and outlet (not shown). When the fan rotates, external air drawn in from the intake port and entering the airflow path passes sequentially through the filter, fan, and outlet before being blown out of the space purification device 1000. Consequently, air in contact with the electrolyzed water in the humidification tank 300 is released to the outside. The space purification device 1000 releases active oxygen species (including those from the volatile electrolyzed water) along with the air.

[0044] The water shortage buoy 160 installed in the water storage tank 100, the full water buoy 250 and water shortage buoy 260 installed in the electrolysis tank 200, the full water buoy 350 and water shortage buoy 360 installed in the humidification tank 300, and the drainage buoy 370 respectively detect the presence of water or electrolyzed water. Here, water and electrolyzed water are sometimes collectively referred to as "water". The water shortage buoy 160, full water buoy 250, water shortage buoy 260, full water buoy 350, water shortage buoy 360, and drainage buoy 370 are collectively referred to as "buoys". Each buoy has buoyancy and a magnet (not shown), and the position of the magnet is detected by a detection part (not shown). When water is present up to the position of the buoy, the buoy moves to the specified position due to buoyancy, and the detection part detects the magnet installed on the buoy. On the other hand, when water does not reach the position of the buoy, the detection part cannot detect the magnet installed on the buoy.

[0045] Water shortage buoy 160 detects the water shortage in water storage tank 100. Full water buoy 250 detects the fullness of electrolytic cell 200, and water shortage buoy 260 detects the water shortage in electrolytic cell 200. Here, water shortage may not be 100% water shortage; a small amount of water may remain. In this embodiment, water shortage buoy 260 may also be referred to as a water shortage detection unit. Furthermore, full water buoy 350 detects the fullness of humidification tank 300, water shortage buoy 360 detects the water shortage in humidification tank 300, and drainage buoy 370 detects the drainage level of humidification tank 300. Here, full water may not be 100% full; the amount of water that can still be added may be present. Each buoy sends its detection results to control unit 500.

[0046] The control unit 500 receives detection results from the low-water buoy 160, full-water buoy 250, low-water buoy 260, full-water buoy 350, low-water buoy 360, and drain buoy 370. Furthermore, the control unit 500 controls the electrode unit 210, purification unit 310, electrolysis promoter addition unit 400, first supply unit 128, second supply unit 138, and third supply unit 228. Details of the processing by the control unit 500 will be described later.

[0047] As an example, the concentration of the electrolyzed water generated in the electrolyzer 200 is in the range of 30 to 200 ppm (hereinafter referred to as "first concentration"), and the concentration of the electrolyzed water diluted in the humidification tank 300 is in the range of 3 to 50 ppm. The concentration of the electrolyzed water diluted in the humidification tank 300 is set to be relatively low compared to the concentration of the electrolyzed water generated in the electrolyzer 200.

[0048] (2) Initial processing

[0049] The initial treatment is the process of releasing water from a state where there is no 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 outlines the operation of the space purification device 1000.

[0050] Figure 2A This indicates a state where there is no water in the water storage tank 100, electrolysis tank 200, and humidification tank 300. This is equivalent to the situation after purchasing and installing the space purification device 1000. Furthermore, it also corresponds to the situation after cleaning and maintenance of the water storage tank 100, electrolysis tank 200, and humidification tank 300.

[0051] Figure 2B Is following Figure 2A The user then fills the water supply tank 110 with water 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.

[0052] Figure 2C Is following 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. Water supply continues until the full water level is detected by the full water float 350. As a result, the humidification tank 300 stores water in a full state.

[0053] The control unit 500 supplies water from the storage tank 100 to the electrolyzer 200 by activating the first pump 120. During this time, water is supplied for a certain period of time while the electrolyzer 200 is not yet full. As a result of this water supply, the water level in the electrolyzer 200 is lower than the full water level. A supply area 240 is provided on a portion of the water surface in the electrolyzer 200, located below the supply port 124 and the inlet port 404. After the water supply is completed, the control unit 500 dispenses the electrolysis promoter 410 from the inlet port 404 into the supply area 240 of the electrolyzer 200. As a result, the electrolysis promoter 410, present in the supply area 240, begins to dissolve in the water.

[0054] Next, the control unit 500 supplies water from the storage tank 100 to the electrolysis tank 200 by activating the first pump 120 again. At this time, water is supplied from the supply port 124 to the supply area 240, thus further promoting the dissolution of the electrolysis promoter 410 due to the pressure of the supplied water. Water supply continues until the full-water buoy 250 detects that the tank is full. As a result, the humidification tank 300 stores water containing some or all of the dissolved chloride ions from the electrolysis promoter 410 in a full-water state.

[0055] Figure 3A and Figure 3B Indicates succession Figures 2A to 2CA summary of the operation of the subsequent space purification device 1000.

[0056] Figure 3A Is following Figure 2C The subsequent state: 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) (e.g., 10 minutes). As a result, electrolyzed water of the second concentration, which is lower than the first concentration, is generated.

[0057] Figure 3B Is following Figure 3A The subsequent state. When the second concentration of electrolyzed water is generated, the control unit 500 supplies the second concentration of electrolyzed water to the humidification tank 300 by activating the third pump 220. At this time, because a metering cylinder 224 is used, the second concentration of electrolyzed water of the metering cylinder 224 volume is supplied to the humidification tank 300. The second concentration of electrolyzed water is diluted in the humidification tank 300. The control unit 500 releases the air that has come into contact with the electrolyzed water in the humidification tank 300 to the outside of the space purification device 1000 by activating the purification unit 310 after stopping the third pump 220. That is, the release of air that has come into contact with the electrolyzed water begins from a time of less than 40 minutes.

[0058] (3) Normal processing

[0059] The treatment is typically used to release electrolyzed water of the required concentration. Figure 4A and Figure 4B Indicates succession Figure 3A and Figure 3B A summary of the operation of the subsequent space purification device 1000.

[0060] Figure 4A Is following Figure 3B The subsequent state: A portion of the second concentration of electrolyzed water in electrolyzer 200 is supplied to humidification tank 300, so the second concentration of electrolyzed water is stored in electrolyzer 200 in a partially filled state. Control unit 500 supplies water from storage tank 100 to electrolyzer 200 by activating first pump 120. At this time, as water is supplied from supply port 124 to supply area 240, the dissolved residual electrolysis promoter 410 is further dissolved due to the pressure of the supplied water. Water supply continues until the full-water buoy 250 detects full water. As a result, electrolyzer 200 becomes full. After the water supply to electrolyzer 200 is completed, control unit 500 generates electrolyzed water by electrolysis by energizing electrode unit 210. Here, the electrolysis time is set to the time required to generate first concentration of electrolyzed water (e.g., 40 minutes). As a result, first concentration of electrolyzed water is generated.

[0061] Figure 4B Is following Figure 4A The subsequent state: When the first concentration of electrolyzed water is generated, the control unit 500 supplies the first concentration of electrolyzed water to the humidification tank 300 by activating the third pump 220. At this time, because a metering cylinder 224 is used, the first concentration of electrolyzed water of the metering cylinder 224 volume is supplied to the humidification tank 300. The first concentration of electrolyzed water is diluted in the humidification tank 300. The control unit 500 releases the air that has come into contact with the electrolyzed water in the humidification tank 300 to the outside of the space purification device 1000 by activating the purification unit 310 after stopping the third pump 220.

[0062] When air in contact with the electrolyzed water is released, the amount of electrolyzed water in the humidification tank 300 decreases. When the water shortage buoy 360 detects a water shortage, the control unit 500 supplies the humidification tank 300 with an amount of electrolyzed water of the first concentration corresponding to the capacity of the metering cylinder 224 by activating the third pump 220, and supplies water to the water storage tank 100 by activating the second pump 130, until the humidification tank 300 is full. Thus, the release of electrolyzed water continues. This process is repeated until the water shortage buoy 260 detects a water shortage.

[0063] (4) Restart process

[0064] Restart processing is a procedure performed to repeat the normal processing when the water shortage buoy 260 detects a water shortage, i.e., when the electrolyzed water in the electrolyzer 200 is low. When the water shortage buoy 260 detects a water shortage after supplying electrolyzed water of the first concentration to the humidification tank 300, the control unit 500 begins supplying water to the electrolyzer 200 through the first supply unit 128. That is, the control unit 500 does not supply water to the electrolyzer 200 until it is low on water. This is to maintain the concentration of the electrolyzed water in the electrolyzer 200 at the first concentration by not supplying water. It also makes it difficult for old electrolyzed water to remain in the electrolyzer 200, thus making it difficult for impurities such as inorganic salt compounds to remain in the electrolyzer 200. Therefore, the maintenance frequency of the electrolyzer 200 is reduced.

[0065] Here, similar to the initial treatment, the control unit 500 supplies water for a certain period of time while the electrolytic cell 200 remains at a constant level of full water. Next, the control unit 500 adds the electrolysis promoter 410 from the inlet 404 into the supply area 240 of the electrolytic cell 200, continuing this water supply until the electrolytic cell 200 is full. Then, the control unit 500 generates electrolyzed water of a second concentration by energizing the electrode section 210, and supplies this second-concentration electrolyzed water from the electrolytic cell 200 to the humidification tank 300. That is, a portion of the treatment is performed similarly to the initial treatment. Next, normal treatment is performed.

[0066] (5) Treatment of electrolysis accelerator addition

[0067] As described above, the electrolysis accelerator feeding unit 400 feeds the electrolysis accelerator 410 into the electrolytic cell 200. The structure and operation related to the feeding of the electrolysis accelerator 410 will now be explained.

[0068] Figure 5 This is an exploded perspective view of the electrolysis accelerator input section 400, showing a portion of the casing 420 cut away so that the interior of the casing 420 can be seen. Figure 6 This is a perspective view showing the interior of the housing 420 of the electrolysis accelerator injection section 400, especially an enlarged perspective view of the hole 440 in the housing 420 and the notch 434 in the rotating body 424. It is a diagram showing the electrolysis accelerator 410 falling through the notch 434 in the rotating body 424 and the hole 440 in the housing 420.

[0069] like Figure 5 , Figure 6 As shown, the electrolysis accelerator feeding unit 400 includes a housing 420, a housing cover 422, a rotating body 424, a motor unit 426, a light-emitting unit 450, and a light-receiving unit 452. The housing 420 is a circular basin shape with an opening at the top, and the upper end is detachable from the bowl-shaped housing cover 422 with an opening at the bottom. The rotating body 424 is included inside the housing 420, and the motor unit 426 is included at the bottom of the housing. The motor unit 426 causes the rotating body 424 to rotate within the housing 420 with the vertical direction as the rotation axis. The rotating body 424 corresponds to the aforementioned tablet feeding component. A bearing hole 428 and a hole 440 are provided on the bottom surface of the housing 420. The bearing hole 428 is a hole for the rotation shaft 432 of the rotating body 424, described later, to enter. The hole 440 is a hole through which the electrolysis accelerator 410 passes. A guide tube 442 extending downward from the opening edge of the hole 440 is provided in the hole 440.

[0070] The light-emitting part 450 is disposed perpendicularly to the passage direction of the electrolytic accelerator 410, on the side of the hole 440 and the guide tube 442 through which the electrolytic accelerator 410 passes. The light-emitting part 450 is, for example, composed of an infrared LED (light-emitting diode) and is arranged to emit light toward the passage position of the electrolytic accelerator 410.

[0071] The light-receiving part 452 is positioned to the side of the hole 440 through which the electrolytic accelerator 410 passes and the guide tube 442, sandwiching the hole 440 and opposite to the light-emitting part 450. The light-receiving part 452 is configured such that its light-receiving surface faces the passage position of the electrolytic accelerator 410, enabling it to receive light from the light-emitting part 450. When light is received from the light-emitting part 450, the light-receiving part 452 outputs a signal based on the intensity of the received light. One way the light-receiving part 452 outputs a signal is, for example, when the light is blocked by the electrolytic accelerator 410, i.e., the intensity of the received light decreases, the signal intensity decreases.

[0072] The rotating body 424 has a convex portion 430 and a cylindrical rotating shaft 432 extending downward from the central lower surface of the convex portion 430, wherein the convex portion 430 is a circular plate protruding upward from its central portion. The convex portion 430 and the rotating shaft 432 are integrally formed of resin material. The convex portion 430 is slightly smaller than the housing 420, and there is a small gap between the outer periphery of the convex portion 430 and the inner surface of the housing 420. A notch 434 is provided at the periphery of the convex portion 430. Electrolysis accelerator 410 enters the notch 434, and when it coincides with the hole 440, the electrolysis accelerator 410 is introduced into the electrolytic cell 200.

[0073] In this structure, it is very rare for the control unit 500 to instruct the electrolysis accelerator 410 to be added to the electrolysis accelerator addition unit 400, but not to detect a decrease in the intensity of the light received in the light-receiving unit 452, i.e., not to detect the passage of the electrolysis accelerator 410. This can occur for two reasons. The first reason is that although the electrolysis accelerator 410 is added to the electrolytic cell 200 through the notch 434 and the hole 440, the decrease in the intensity of the light received in the light-receiving unit 452 is small. This is a false detection caused by the light-receiving unit 452. The second reason is that although the notch 434 and the hole 440 coincide due to the rotation of the rotating body 424, the electrolysis accelerator 410 is not added to the electrolytic cell 200 through the notch 434 and the hole 440. This can happen, for example, when the electrolysis accelerator 410 continuously dissolves and adheres to the wall of the notch 434. Furthermore, when the electrolysis accelerator 410 is repeatedly added to the electrolysis accelerator feeding section 400 and the electrolysis accelerator 410 in the electrolysis accelerator feeding section 400 is used up, there may be a situation where the passage of the electrolysis accelerator 410 cannot be detected.

[0074] As mentioned above, in such a situation, an instruction to add electrolysis accelerator 410 is issued again. As a result, especially in the case of the first reason, more electrolysis accelerator 410 than predetermined is added, resulting in electrolyzed water with a hypochlorous acid concentration higher than the reference value. In order to prevent the concentration of hypochlorous acid in the electrolyzed water from becoming higher than the reference value, the space purification device 1000 of this embodiment performs the following treatment.

[0075] Figure 7This section represents the functional blocks of the space purification device 1000. The space purification device 1000 includes a light-emitting unit 450, a light-receiving unit 452, an electrolyzed water generating unit 460, a control unit 500, and a notification unit 530. The electrolyzed water generating unit 460 includes an electrode unit 210 and an electrolysis promoter addition unit 400. The control unit 500 includes an addition indicator unit 510, an addition detection unit 512, a non-addition detection count unit 514, and a power-on processing unit 520. The power-on processing unit 520 includes a power-on setting determination unit 522.

[0076] The input instruction unit 510 instructs the electrolysis accelerator 410 to be input into the electrolysis accelerator input unit 400. The timing of the input of the electrolysis accelerator 410 is as described above. The input instruction unit 510 instructs the electrolysis accelerator 410 to be input and instructs the light-emitting unit 450 to emit light, and notifies the non-input detection count unit 514 of the instruction to input the electrolysis accelerator 410.

[0077] The input detection unit 512 detects whether the electrolysis accelerator 410 has passed through the aperture 440, i.e., whether the electrolysis accelerator 410 has been input, based on the signal from the light-receiving unit 452. For example, if the intensity of the received light is lower than a threshold, the input detection unit 512 determines that the electrolysis accelerator 410 has passed through the aperture 440; if the intensity of the received light is higher than the threshold, it determines that the electrolysis accelerator 410 has not passed through the aperture 440. The threshold is preset, for example, through simulation or experiment. Therefore, the aforementioned "signal based on the light-receiving unit 452" refers to signal attenuation, i.e., a decrease in light intensity. The input detection unit 512 outputs the detection result to the input indicator unit 510, the non-input detection count unit 514, and the power-on processing unit 520.

[0078] If the detection result received from the input detection unit 512 does not indicate the input of electrolysis accelerator 410, the input instruction unit 510 repeats the previous process. Specifically, the input instruction unit 510 instructs the electrolysis accelerator input unit 400 to input the electrolysis accelerator 410, instructs the light-emitting unit 450 to emit light, and then notifies the non-input detection count unit 514 of the input instruction of the electrolysis accelerator 410. This process is repeated when the input of the electrolysis accelerator 410 is detected by the input detection unit 512. An upper limit can also be set for the number of repetitions as described later.

[0079] The non-input detection count unit 514 receives instructions from the input instruction unit 510 regarding the input of the electrolysis accelerator 410 and receives detection results from the input detection unit 512. The non-input detection count unit 514 counts the number of times the input instruction unit 510 indicated the input of the electrolysis accelerator 410 but the input detection unit 512 did not detect the input of the electrolysis accelerator 410. This number is called the "non-input detection count". The non-input detection count is reset when the detection results received from the input detection unit 512 show that the electrolysis accelerator 410 has been input, or when the number of repetitions of the input instruction in the input instruction unit 510 reaches its upper limit.

[0080] The power-on setting determination unit 522 receives the number of non-input detections from the non-input detection count unit 514. Based on the number of non-input detections, the power-on setting determination unit 522 determines the power-on setting for electrolysis in the water electrolysis generation unit 460. For example, the power-on setting is the setting of the power-on time; the more non-input detections, the shorter the power-on time is set by the power-on setting determination unit 522. Specifically, the power-on setting determination unit 522 determines the power-on time by a predetermined value of the power-on time (hereinafter referred to as "predetermined time") / (1 + number of non-input detections). An example of the predetermined time is the aforementioned "40 minutes". Therefore, when no detections fail in the input detection unit 512, the power-on time is the predetermined time.

[0081] Figure 8 This section outlines the processing in the power-on setting decision unit 522. Here, scenarios "1" to "6" are considered. Scenario "1" to "3" correspond to the first cause mentioned above. Scenario "4" to "6" correspond to the second cause mentioned above. In scenario "1", when the input instruction unit 510 instructs for the first input, the electrolysis accelerator input unit 400 successfully inputs the accelerator, but the input detection unit 512 fails to detect it. Then, when the input instruction unit 510 instructs for a retry of the first input, the electrolysis accelerator input unit 400 successfully inputs the accelerator, and the input detection unit 512 also successfully detects it. As a result, the number of non-input detections is "1", and the number of electrolysis accelerators 410 input is "2". The power-on setting decision unit 522 determines the power-on time to be "1 / 2" of a predetermined time.

[0082] In scenario "2", when the input instruction unit 510 instructs for the first input, the electrolysis accelerator input unit 400 successfully inputs the accelerator, but the input detection unit 512 fails to detect it. The same occurs during the first retry. When the input instruction unit 510 instructs for a second retry, the electrolysis accelerator input unit 400 successfully inputs the accelerator, and the input detection unit 512 also successfully detects it. As a result, the number of non-input detections is "2", and the number of electrolysis accelerators 410 inputs is "3". The energizing setting determination unit 522 determines the energizing time to be "1 / 3" of the specified time.

[0083] In scenario "3", when the input instruction unit 510 instructs for the first input, the electrolysis accelerator input unit 400 successfully inputs the accelerator, but the input detection unit 512 fails to detect it. The same occurs in the first and second retry attempts. When the input instruction unit 510 instructs for the third retry, the electrolysis accelerator input unit 400 successfully inputs the accelerator, and the input detection unit 512 also successfully detects it. As a result, the number of non-input detection attempts is "3", and the number of electrolysis accelerators 410 inputs is "4". The energizing setting determination unit 522 determines the energizing time to be "1 / 4" of the specified time.

[0084] In scenario "4", when the input instruction unit 510 instructs for the first input, the electrolysis accelerator input unit 400 fails to input, and the input detection unit 512 fails to detect. Then, when the input instruction unit 510 instructs for a retry of the first input, the electrolysis accelerator input unit 400 successfully inputs, and the input detection unit 512 also successfully detects. As a result, the number of non-input detections is "1", and the number of electrolysis accelerators 410 input is "1". The energizing setting determination unit 522 determines the energizing time to be "1 / 2" of the specified time.

[0085] In scenario "5", when the input instruction unit 510 instructs for the first input, the electrolysis accelerator input unit 400 fails to input, and the input detection unit 512 fails to detect it. The same occurs during the first retry. When the input instruction unit 510 instructs for a second retry, the electrolysis accelerator input unit 400 successfully inputs, and the input detection unit 512 also successfully detects it. As a result, the number of non-input detections is "2", and the number of electrolysis accelerators 410 input is "1". The energizing setting determination unit 522 determines the energizing time to be "1 / 3" of the specified time.

[0086] In scenario "6", when the input instruction unit 510 instructs for the first input, the electrolysis accelerator input unit 400 fails to input, and the input detection unit 512 fails to detect it. The same occurs in the first and second retry attempts. When the input instruction unit 510 instructs for the third retry, the electrolysis accelerator input unit 400 successfully inputs, and the input detection unit 512 also successfully detects it. As a result, the number of non-input detections is "3", and the number of electrolysis accelerators 410 input is "1". The energizing setting determination unit 522 determines the energizing time to be "1 / 4" of the specified time.

[0087] In scenarios "1" to "3", the number of electrolysis accelerators 410 added is more than the predetermined number, i.e., "1". However, because the energizing time is shorter than the specified time, it is possible to prevent the concentration of hypochlorous acid in the electrolyzed water from exceeding the reference value. On the other hand, in scenarios "4" to "6", the number of electrolysis accelerators 410 added is the predetermined number, i.e., "1". Again, because the energizing time is shorter than the specified time, although the concentration of hypochlorous acid in the electrolyzed water decreases, it does not exceed the reference value, thus ensuring safety.

[0088] After the addition detection unit 512 detects the addition of the electrolysis promoter 410, the energizing processing unit 520 energizes the counter electrode unit 210 according to the energizing time set by the energizing setting determination unit 522. Accordingly, after the addition detection unit 512 detects the addition of the electrolysis promoter 410, the electrolyzed water generating unit 460 generates electrolyzed water by setting the energizing time.

[0089] When the number of non-input detections counted by the non-input detection count unit 514 exceeds a threshold, the input instruction unit 510 does not instruct the electrolysis accelerator input unit 400 to input the electrolysis accelerator 410. The threshold is, for example, "4". When the number of non-input detections exceeds the threshold, the notification unit 530 notifies the electrolysis accelerator input unit 400 of the input error.

[0090] The main body of the apparatus, system, or method disclosed herein includes a computer. The core functions of the apparatus, system, or method of this disclosure are realized by executing a program on the computer. The computer includes a processor that operates according to the program as its main hardware structure. The type of processor is irrelevant as long as it can perform its functions by executing the program. The processor consists of one or more electronic circuits comprising integrated circuits or large-scale integrated circuits (LSI). Multiple electronic circuits can be integrated on a single chip or disposed across multiple chips. Multiple chips can be integrated into a single device or included in multiple devices. The program is recorded in a non-transitory recording medium such as a computer-readable read-only memory (ROM), 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.

[0091] The operation of the space purification device 1000 with the above structure will be explained. Figure 9 This is a flowchart showing the control sequence executed by the space purification device 1000.

[0092] First, water is supplied to the water storage tank 100 from the outside (S10).

[0093] Next, water is supplied from the water storage tank 100 to the electrolyzer 200 in an amount less than the full volume of water (S12).

[0094] Next, electrolysis accelerator 410 is supplied to electrolytic cell 200 from electrolysis accelerator input section 400 (S14).

[0095] Next, water is supplied from the water storage tank 100 to the electrolyzer 200 until the electrolyzer 200 is full (S16).

[0096] Next, the electrode section 210 performs electrolysis for 10 minutes (S18). As a result, electrolyzed water of a second concentration is generated in the electrolytic cell 200.

[0097] Next, electrolyzed water of a second concentration is supplied from the electrolyzer 200 to the humidification tank 300 (S20). As a result, the electrolyzed water is released from the humidification tank 300.

[0098] Next, water is supplied from the water storage tank 100 to the electrolyzer 200 until the electrolyzer 200 is full (S22).

[0099] Next, the electrode section 210 performs electrolysis for 40 minutes (S24). As a result, electrolyzed water of the first concentration is generated in the electrolytic cell 200.

[0100] Next, electrolyzed water of the first concentration is supplied from the electrolyzer 200 to the humidification tank 300 (S26).

[0101] Next, the purification unit 310 releases electrolyzed water (S28).

[0102] Next, the water shortage buoy 360 is used to determine whether the humidification tank 300 is short of water (S30). If it is determined in step S30 that the humidification tank 300 is not short of water (S30 "No"), the process returns to step S28.

[0103] If it is determined in step S30 that the humidification tank 300 is short of water (S30 "Yes"), the water shortage float 260 is used to determine whether the electrolytic cell 200 is short of water (S32). If it is determined in step S32 that the electrolytic cell 200 is not short of water (S32 "No"), the process returns to step S26.

[0104] If it is determined in step S32 that the electrolytic cell 200 is short of water (S32 is "Yes"), the process returns to step S12.

[0105] Figure 10 This is a flowchart showing the power-on sequence performed by the space purification device 1000.

[0106] First, the non-input detection count unit 514 sets the non-input detection count to 0 (S50).

[0107] Next, the input instruction unit 510 instructs the electrolysis accelerator input unit 400 to input the electrolysis accelerator 410 (S52).

[0108] Next, the input detection unit 512 determines whether the input of the electrolysis accelerator 410 has been detected (S54). When the input detection unit 512 detects the input of the electrolysis accelerator 410 in step S54 (S54 "Yes"), the power-on setting determination unit 522 determines the power-on setting based on the number of non-input detections (S56). Then, the electrolyzed water generation unit 460 generates electrolyzed water according to the power-on setting (S58).

[0109] If the electrolysis promoter 410 is not detected by the detection unit 512 in step S54 (S54 is "No"), the non-input detection count unit 514 increments the non-input detection count by "1" (S60). Then, the non-input detection count unit 514 determines whether the non-input detection count is "4" (S62).

[0110] If it is determined in step S62 that the number of non-input detections is not "4" ("No" in S62), the process returns to step S52.

[0111] If the non-input detection count is determined to be "4" in step S62 ("No" in S62), the notification unit 530 notifies of an input error (S64).

[0112] According to this embodiment, since the power-on setting is determined based on the number of non-detection cycles, a power-on setting that includes false detections can be determined even if false detections occur. Furthermore, because a power-on setting that includes false detections is made even if false detections occur, the concentration of hypochlorous acid in the electrolyzed water can be prevented from exceeding the reference value. Moreover, because the concentration of hypochlorous acid in the electrolyzed water can be prevented from exceeding the reference value, safety can be ensured. Furthermore, since the addition of the electrolysis accelerator 410 is indicated until its addition is detected, and electrolyzed water is generated by power-on setting after the addition of the electrolysis accelerator 410 is detected, electrolyzed water can be reliably generated.

[0113] Furthermore, since the more non-input detections occur, the shorter the energizing time can be set, the increase in hypochlorous acid concentration in the electrolyzed water can be suppressed even if a large amount of electrolysis accelerator 410 is added. Moreover, since the addition of electrolysis accelerator 410 is not indicated when the number of non-input detections exceeds a threshold, the operation of the space purification device 1000 can be stopped when there is a risk of malfunction. Furthermore, since an error is reported when the number of non-input detections exceeds a threshold, the occurrence of a malfunction can be reported. Furthermore, since an error is reported when an error is reported when the number of non-input detections exceeds a threshold, it is possible to report that the electrolysis accelerator 410 in the electrolysis accelerator addition unit 400 has been used up.

[0114] Furthermore, the water treatment tank is divided into a water storage tank 100, an electrolysis tank 200, and a humidification tank 300, thus suppressing the occurrence of gas-liquid contact between the water in the electrolysis tank 200 used relative to the electrode section 210. Moreover, because the occurrence of gas-liquid contact between the water in the electrolysis tank 200 and the electrolysis tank 200 is suppressed, the water in the electrolysis tank 200 is less likely to become contaminated. Furthermore, because the water in the electrolysis tank 200 is less likely to become contaminated, electrode degradation is suppressed. Furthermore, because the second concentration of electrolyzed water is supplied to and discharged from the humidification tank 300, the time until the electrolyzed water is discharged is shortened. Furthermore, because the first concentration of electrolyzed water is generated after the second concentration of electrolyzed water, the desired concentration of electrolyzed water can be discharged. Furthermore, because the electrolysis promoter 410 is added to the supply area 240 and water is supplied to the supply area 240, the dissolution of the electrolysis promoter 410 can be promoted using water pressure. Furthermore, since the first concentration of electrolyzed water is generated through normal processing after water is supplied to the electrolyzer 200, the electrolysis promoter 410 can be easily dissolved.

[0115] 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. Moreover, because no water supply is required until a water shortage is detected, the concentration of electrolyzed water in the electrolyzer 200 can be maintained. Furthermore, because no water supply is required until a water shortage is detected, impurities remaining in the electrolyzer 200 can be flushed away. Since a portion of the initial treatment is performed as a restart process, the operation is simplified.

[0116] A summary of one aspect of this disclosure is described below. A space purification device (1000) according to one aspect of this disclosure includes: an electrolytic cell (200) for retaining water and electrolyzing water; an electrolysis accelerator input unit (400) for inputting an electrolysis accelerator (410) into the electrolytic cell (200); an electrolyzed water generation unit (460) for electrolyzing water containing the electrolysis accelerator (410) to generate electrolyzed water; a purification unit (310) for contacting the electrolyzed water generated by the electrolyzed water generation unit (460) with air drawn in from an air intake; an input indicator unit (510) for instructing the input of the electrolysis accelerator (410) to the electrolysis accelerator input unit (400); and an input detection unit (512). The unit includes a detection unit (400) for the addition of electrolysis promoter (410); a non-addition detection count unit (514) for counting non-addition detection counts, wherein the non-addition detection count is the number of times that the addition of electrolysis promoter (410) was indicated by the addition instruction unit (510) but the addition of electrolysis promoter (410) was not detected by the addition detection unit (512); and an energizing setting determination unit (522) for determining the energizing setting for electrolysis in the electrolyzed water generation unit (460) based on the non-addition detection count counted by the non-addition detection count unit (514).

[0117] The input instruction unit (510) can also instruct the input unit (400) to input the electrolysis accelerator (410) until the input detection unit (512) detects the input of the electrolysis accelerator (410). After the input detection unit (512) detects the input of the electrolysis accelerator (410), the electrolyzed water generation unit (460) generates electrolyzed water according to the power-on setting.

[0118] The power-on setting can include the setting of the power-on time in the water electrolysis generation unit (460). The more non-input detections are performed, the shorter the power-on time will be set by the power-on setting determination unit (522).

[0119] The power-on setting may also include the setting of the power-on current value in the water electrolysis generation unit (460). Alternatively, the more non-input detections are performed, the smaller the power-on current value will be set by the power-on setting determination unit (522).

[0120] The power-on setting may also include setting the power-on voltage value in the water electrolysis generation unit (460). Alternatively, the more non-input detections are performed, the lower the power-on voltage value will be set by the power-on setting determination unit (522).

[0121] The input instruction unit (510) may also not instruct the electrolysis accelerator input unit (400) to input the electrolysis accelerator (410) when the number of non-input detections exceeds the threshold.

[0122] It may also include a notification unit (530) that notifies the electrolysis accelerator input unit (400) of input errors when the number of non-input detections exceeds a threshold.

[0123] The present disclosure has been described above based on embodiments. These embodiments are illustrative, and those skilled in the art will understand that various modifications are possible for the combination of the above-described constituent elements or processing procedures, and such modifications are also included within the scope of the present disclosure.

[0124] In this embodiment, the power-on setting determination unit 522 sets the power-on time as the power-on setting. However, it is not limited to this; for example, the power-on setting determination unit 522 can also set the power-on current value as the power-on setting. In this case, the more times the non-intrusion detection is performed, the smaller the power-on current value will be set by the power-on setting determination unit 522. Furthermore, the power-on setting determination unit 522 can also set the power-on voltage value as the power-on setting. In this case, the more times the non-intrusion detection is performed, the smaller the power-on voltage value will be set by the power-on setting determination unit 522. According to this modified example, the degree of freedom in configuration can be increased.

[0125] The space purification device 1000 in this embodiment includes an electrolytic cell 200 and a humidification tank 300. However, it is not limited to this; for example, the electrolytic cell 200 and the humidification tank 300 may also be integrated as a water storage unit. According to this modified example, the structure of the space purification device 1000 can be simplified.

[0126] In this embodiment, the water shortage buoy 260 detects water shortage by the position of a magnet in the buoy. However, it is not limited to this; for example, water shortage can also be detected based on the number of times water is supplied by the metering cylinder 224. For example, when the electrolytic cell 200 has a capacity of 1000 ml and the metering cylinder 224 has a capacity of 250 ml, water shortage is detected after supplying water four times by the metering cylinder 224. According to this modified example, the degree of freedom in configuration can be increased.

[0127] 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 again after a certain period of time. According to this variation, the degree of freedom in configuration can be increased.

[0128] Furthermore, the control unit 500 may also include a storage unit for storing currently executed control content. An example of such a storage unit is a non-volatile memory. The control unit 500 periodically stores the currently executed control content in the storage unit as needed. The control unit 500 can also control the space purification device 1000 based on the executed control content stored in the storage unit when power is restored after a power outage in the space purification device 1000. That is, the control unit 500 can also restart based on the executed control content stored in the storage unit when power is restored after a power outage in the space purification device 1000. Therefore, correct control content can be performed even when power is restored after a power outage in the space purification device 1000.
