Description

Technical Field

[0001] The present disclosure relates to a space purification device. Background Art

[0002] There has been known a space purification device that generates and discharges electrolyzed water containing hypochlorous acid through electrolysis in order to remove (including inactivate) bacteria, fungi, viruses, odors and the like in the air (see, for example, Patent Document 1). For the generation of hypochlorous acid, it is necessary to add an electrolysis accelerator such as salt to water to be electrolyzed, so as to prepare water containing chloride ions in advance.

[0003] Patent Document 1 Japanese Unexamined Patent Publication No. 2019-24811 Summary of Invention

[0004] When automatically adding the electrolysis accelerator in a space purification device, a function for detecting 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 arranged across the feeding path of the electrolysis accelerator, and the addition of the electrolysis accelerator is detected when the light-receiving level at the light-receiving unit decreases. In such a configuration, if no addition is detected even after an instruction for adding the electrolysis accelerator is issued, the addition of the electrolysis accelerator will be instructed again. However, if the detection of addition fails even though the electrolysis accelerator has actually been added, an additional amount of electrolysis accelerator will be added. As a result, the concentration of hypochlorous acid in the electrolyzed water may become higher than the reference value.

[0005] An object of the present disclosure is to provide a technique for suppressing the concentration of hypochlorous acid in electrolyzed water from becoming higher than a reference value.

[0006] An air purification device in one aspect of the present disclosure includes: an electrolytic cell for storing water and electrolyzed water; an electrolytic accelerator input unit for adding an electrolytic accelerator to the electrolytic cell; an electrolyzed water generation unit for electrolyzing the water into which the electrolytic accelerator has been added to generate electrolyzed water; a purification unit for bringing the electrolyzed water generated by the electrolyzed water generation unit into contact with air drawn in from an air intake port; an input instruction unit for instructing the electrolytic accelerator input unit to add an electrolytic accelerator; an input detection unit for detecting the addition of the electrolytic accelerator by the electrolytic accelerator input unit; a non-input detection count unit for counting the number of times the input detection unit has not detected the addition of the electrolytic accelerator despite the input instruction unit having instructed the input of the electrolytic accelerator; and a power setting determination unit for determining the power setting for electrolysis in the electrolyzed water generation unit based on the number of non-input detections counted by the non-input detection count unit.

[0007] Furthermore, any combination of the above components, as well as any conversion of the expressions of this disclosure between methods, apparatus, systems, recording media, computer programs, etc., are also valid forms of this disclosure.

[0008] According to this disclosure, it is possible to suppress the concentration of hypochlorous acid in electrolyzed water from exceeding a standard value. [Brief explanation of the drawing]

[0010] Before specifically describing the embodiments of this disclosure, an overview of the embodiments will be given. This embodiment relates to a space purification device that generates and releases electrolyzed water based on water and an electrolytic accelerator. In the space purification device, if the addition of the electrolytic accelerator is not detected even after being instructed to do so, the addition of the electrolytic accelerator is instructed again. For example, if the addition of the electrolytic accelerator is actually added but detection fails, additional electrolytic accelerator is added. As a result, although only one tablet of the electrolytic accelerator should be added to the water, two or more tablets of the electrolytic accelerator are added to the water. In this situation, when the water with the added electrolytic accelerator is electrolyzed, electrolyzed water with a hypochlorous acid concentration higher than the standard value is produced. Since the release of electrolyzed water with a hypochlorous acid concentration higher than the standard value is undesirable, even when the addition of the electrolytic accelerator is instructed again, it is necessary to suppress the concentration of hypochlorous acid in the electrolyzed water from exceeding the standard value.

[0011] The air purification device according to this embodiment counts the number of times when the addition of an electrolytic accelerator is not detected despite being instructed to do so, although this is unlikely. The air purification device also adjusts the energizing time for electrolysis according to the number of non-addition detections when the addition is detected. For example, the more non-addition detections there are, the shorter the energizing time is. In this way, even if a large amount of electrolytic accelerator is added, the energizing time is shortened, thus suppressing an excessive increase in the concentration of hypochlorous acid in the electrolyzed water.

[0012] Furthermore, conventional air purification devices generate water containing chloride ions by dissolving an electrolysis accelerator in the water reservoir, and then generate electrolyzed water containing reactive oxygen species by electrolyzing the chloride ion-containing water by passing electricity through electrodes. In addition, conventional air purification devices continuously bring the generated electrolyzed water into contact with air drawn in from the outside in the water reservoir, and then release the contacted air to the outside by rotating a fan. As a result, the electrolyzed water in the reservoir is prone to contamination due to contact with air. If the electrolyzed water becomes contaminated, the electrodes may deteriorate.

[0013] To suppress electrode deterioration, the air purification device according to this embodiment divides the water storage section into two tanks: an electrolytic cell and a humidifying tank. The electrolytic cell is equipped with electrodes, which electrolyze water containing chloride ions to produce electrolyzed water. The electrolyzed water produced in the electrolytic cell is supplied to the humidifying tank. Furthermore, in the humidifying tank, the electrolyzed water from the electrolytic cell is continuously brought into contact with air drawn in from the outside, and then the air that has been in contact is released to the outside by the rotation of a fan. With this configuration, the electrolyzed water in the electrolytic cell does not come into contact with air, so it is less likely to get dirty, and electrode deterioration is suppressed.

[0014] The embodiments for implementing this disclosure will be described below with reference to the attached drawings. Figure 1 shows the internal configuration of the air purification device 1000.

[0015] The space purification apparatus 1000 includes a water storage tank 100, a water supply tank 110, a lid 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 low water float 160, an electrolysis tank 200, an electrode unit 210, a third pump 220, a third water supply pipe 222, a quantitative tank 224, a third water supply pipe 226, a full water float 250, a low water float 260, a humidification tank 300, a purification unit 310, a full water float 350, a low water float 360, a drain float 370, an electrolysis accelerator feeding unit 400, a feeding port 404, an electrolysis accelerator 410, and a control unit 500. Here, the first pump 120, the first water supply pipe 122, and the supply port 124 are included in a first supply unit 128, and the second pump 130 and the second water supply pipe 132 are included in a second supply unit 138. The third pump 220, the third water supply pipe 222, the quantitative tank 224, and the third water supply pipe 226 are included in a third supply unit 228. It should be noted that the fact that the control unit 500 controls the operations of each component included in the space purification apparatus 1000 is also referred to as the control unit 500 controlling the operation of the space purification apparatus 1000. Hereinafter, description will be given in the order of (1) Basic Configuration, (2) Initial Processing, (3) Normal Processing, (4) Restart Processing, and (5) Electrolysis Accelerator Feeding Processing.

[0016] (1) Basic Configuration The water storage tank 100 has a box shape with an open top surface, has a structure capable of storing water, and stores water supplied from the water supply tank 110 described later. The water storage tank 100 is disposed, for example, in a lower portion of the space purification apparatus 1000. The water supply tank 110 is a tank that stores water therein, and is attachable to and detachable from the water storage tank 100. A lid 112 is provided at an opening (not shown) of the water supply tank 110, and an opening / closing unit (not shown) is provided at the center of the lid 112. When the opening / closing unit opens, the water in the water supply tank 110 is supplied to the water storage tank 100.

[0017] Specifically, when the water supply tank 110 is attached to the water storage tank 100 with the opening of the water supply tank 110 facing downward, the opening / closing part opens. That is, when the water supply tank 110 filled with water is attached to the water storage tank 100, the opening / closing part opens to supply water to the water storage tank 100, and water accumulates in the water storage tank 100. When the water level in the water storage tank 100 rises and reaches the lid 112, the opening of the water supply tank 110 is water-sealed, so the water supply stops. When water remains inside the water supply tank 110, water inside the water supply tank 110 is supplied to the water storage tank 100 every time the water level in the water storage tank 100 drops. As a result, the water level in the water storage tank 100 is maintained constant.

[0018] The first pump 120 is disposed inside the water storage tank 100 and connected to the first water supply pipe 122. When the first pump 120 operates in response to an instruction from the control unit 500, it pumps up the water stored in the water storage tank 100 toward 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 end on the electrolytic cell 200 side. The water pumped up by the first pump 120 flows through the first water supply pipe 122 and is supplied from the supply port 124 to the electrolytic cell 200. 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.

[0019] The second pump 130 is disposed inside the water storage tank 100 and connected to the second water supply pipe 132. When the second pump 130 operates in response to an instruction from the control unit 500, it pumps up the water stored in the water storage tank 100 toward 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 pumped up by the second pump 130 flows through 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.

[0020] The electrolytic cell 200 has a box shape with an open top and is located below the supply port 124. The electrolytic cell 200 stores water supplied from the supply port 124. An electrolytic accelerator input unit 400 is located above the electrolytic cell 200, next to the supply port 124. The electrolytic accelerator input unit 400 can be loaded with an electrolytic accelerator 410, and when the control unit 500 issues an instruction to input the electrolytic accelerator 410, it rotates a tablet input member (not shown). When the tablet input member rotates, the electrolytic accelerator 410 falls into the electrolytic cell 200. The electrolytic accelerator input unit 400 counts the number of electrolytic accelerators 410 that have fallen into the electrolytic cell 200, and when it determines that one tablet of electrolytic accelerator 410 has fallen into the electrolytic cell 200, it stops rotating the tablet input member. In other words, the electrolytic accelerator input unit 400 inputs the electrolytic accelerator 410 into the electrolytic cell 200. When the electrolysis accelerator 410 dissolves in the water in the electrolysis cell 200, water containing chloride ions is generated in the electrolysis cell 200. An example of the electrolysis accelerator 410 is sodium chloride, which is formed as an electrolysis accelerator tablet.

[0021] The electrode unit 210 is installed so as to be immersed in the water in the electrolytic cell 200. When electricity is passed through the electrode unit 210, it electrochemically decomposes the chloride ion-containing water in the electrolytic cell 200, generating electrolyzed water containing reactive oxygen species. Here, reactive oxygen species refer to oxygen molecules and related substances that have higher oxidative activity than ordinary oxygen. For example, reactive oxygen species include not only so-called reactive oxygen species in the narrow sense, such as superoxide anions, singlet oxygen, hydroxyl radicals, and hydrogen peroxide, but also so-called reactive oxygen species in the broad sense, such as ozone and hypochlorous acid (hypohalous acid).

[0022] The electrode unit 210 may generate electrolyzed water by repeating a cycle multiple times, where one cycle consists of an energizing time for electrolysis and a non-energizing time, i.e., a time when no energy is applied. Providing a non-energizing time for the electrode unit 210 extends the lifespan of the electrode unit 210. If the energizing time is longer than the non-energizing time, more electrolyzed water containing a larger amount of reactive oxygen species is generated per cycle. Also, if the non-energizing time is longer than the energizing time, the generation of reactive oxygen species per cycle is suppressed. Furthermore, if the amount of electricity during the energizing time is increased, more electrolyzed water containing a larger amount of reactive oxygen species is generated. Thus, the electrolytic cell 200 can be said to be a tank for generating electrolyzed water from water to which the electrolysis accelerator 410 has been added.

[0023] The third pump 220 is located inside the electrolytic cell 200 and is connected to the third water supply pipe 222. When the third pump 220 operates in response to instructions from the control unit 500, it pumps the electrolyzed water stored in the electrolytic cell 200 towards the third water supply pipe 222. The third water supply pipe 222 is connected to a metering tank 224 and supplies the electrolyzed water from the electrolytic cell 200 to the metering tank 224. The metering tank 224 is a tank with a fixed capacity and stores a fixed volume of electrolyzed water supplied from the third water supply pipe 222. The metering tank 224 is connected to the third water supply pipe 226, which extends toward the humidification tank 300. The electrolyzed water stored in the metering tank 224 flows through the third water supply pipe 226 and is supplied to the humidification tank 300. In other words, the third pump 220, the third water supply pipe 222, the measuring tank 224, and the third water supply pipe 226 supply electrolyzed water from the electrolytic cell 200 to the humidifying tank 300.

[0024] The humidifying tank 300 has a box shape with an open top and mixes water supplied from the water storage tank 100 with electrolyzed water supplied from the electrolytic cell 200. This is equivalent to diluting the electrolyzed water supplied from the electrolytic cell 200 with water supplied from the water storage tank 100. A purification unit 310 is provided in the humidifying tank 300.

[0025] The purification unit 310 includes a fan (not shown) and a filter (filter). The fan is, for example, a sirocco fan and rotates in accordance with the control unit 500. As the fan rotates, air is drawn into the interior of the air purification device 1000 from an air intake port (not shown) provided in the housing (not shown) of the air purification device 1000.

[0026] The filter is a component that brings the electrolyzed water stored in the humidifier tank 300 into contact with the indoor air that has been introduced into the air purification device 1000 by the fan. The filter is cylindrical in shape and has holes in its circumference through which air can flow. The filter is rotatably installed in the humidifier tank 300 with its central axis as the center of rotation, so that one end of the filter is immersed in the electrolyzed water stored in the humidifier tank 300 and retains the water. The filter is rotated by a drive unit (not shown) to continuously bring the electrolyzed water and indoor air into contact.

[0027] An airflow path is formed from the air intake to a filter, fan, and outlet (not shown). When the fan rotates, the outside air drawn in from the air intake and entering the airflow path is sequentially blown out of the air purification device 1000 through the filter, fan, and outlet. As a result, the air that has come into contact with the electrolyzed water in the humidification tank 300 is released to the outside. The air purification device 1000 releases the generated reactive oxygen species (including volatile ones) derived from the electrolyzed water along with the air.

[0028] Each of the following floats—a low-water float 160 in the water storage tank 100, a full-water float 250 and a low-water float 260 in the electrolytic cell 200, and a full-water float 350, a low-water float 360, and a drain float 370 in the humidifying tank 300—detects whether or not water or electrolyzed water is present. Here, water and electrolyzed water are sometimes collectively referred to as "water." The low-water float 160, full-water float 250, low-water float 260, full-water float 350, low-water 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 part (not shown). If water is present up to the float's position, the float moves to a predetermined position due to buoyancy, and the detection part detects the magnet on the float. On the other hand, if there is no water present up to the float's position, the detection part can no longer detect the magnet on the float.

[0029] The low water float 160 detects when the water storage tank 100 is low. The full water float 250 detects when the electrolytic cell 200 is full, and the low water float 260 detects when the electrolytic cell 200 is low. Here, "low water" does not necessarily mean 100% low water; a small amount of water may remain. In this embodiment, the low water float 260 may also be called the low water detection unit. In addition, the full water float 350 detects when the humidifier tank 300 is full, the low water float 360 detects when the humidifier tank 300 is low water, and the drain float 370 detects the drain level of the humidifier tank 300. Here, "full water" does not necessarily mean 100% full water; it may mean an amount of water that allows for further addition of water. Each float transmits the detection result to the control unit 500.

[0030] The control unit 500 receives detection results from the low water float 160, full water float 250, low water float 260, full water float 350, low water float 360, and drainage float 370. The control unit 500 also controls the electrode unit 210, the purification unit 310, the electrolytic accelerator input unit 400, the first supply unit 128, the second supply unit 138, and the third supply unit 228. Details of the processing performed by the control unit 500 will be described later.

[0031] For example, the concentration of electrolyzed water produced in the electrolytic cell 200 is in the range of 30-200 ppm (hereinafter referred to as the "first concentration"), and the concentration of electrolyzed water diluted in the humidifying tank 300 is in the range of 3-50 ppm. The concentration of electrolyzed water diluted in the humidifying tank 300 is set lower than the concentration of electrolyzed water produced in the electrolytic cell 200.

[0032] (2) Initial processing The initial treatment process involves releasing the electrolyzed water in the initial stage, starting from a state where there is no water in the water storage tank 100, electrolytic cell 200, and humidifying tank 300. Figures 2A-2C, 3A, and 3B will also be used below to explain the initial treatment. Figures 2A-2C show an overview of the operation of the air purification device 1000.

[0033] Figure 2A shows a state where there is no water in the water storage tank 100, electrolytic cell 200, and humidifier tank 300. This corresponds to the state after purchasing and installing the air purification device 1000. It also corresponds to the state after cleaning and other maintenance of the water storage tank 100, electrolytic cell 200, and humidifier tank 300.

[0034] Figure 2B shows the state following Figure 2A. The user pours water into the water supply tank 110 and attaches the water supply tank 110 to the water storage tank 100. When the water supply tank 110 is attached to the water storage tank 100, the opening and closing part of the lid 112 opens, supplying water from the water supply tank 110 to the water storage tank 100.

[0035] Figure 2C shows the state following Figure 2B. The control unit 500 operates the second pump 130 to supply water from the water storage tank 100 to the humidifying tank 300. Water is supplied until the full water float 350 detects that the tank is full. As a result, the humidifying tank 300 stores water at full capacity.

[0036] The control unit 500 operates the first pump 120 to supply water from the water storage tank 100 to the electrolytic cell 200. At this time, water is supplied for a certain period of time so as not to fill the electrolytic cell 200 to capacity. 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 located in a portion of the water surface in the electrolytic cell 200, and the supply area 240 is located below the supply port 124 and the inlet port 404. After the water supply is finished, the control unit 500 drops the electrolytic accelerator 410 from the inlet port 404 towards the supply area 240 of the electrolytic cell 200. As a result, the electrolytic accelerator 410 is present in the supply area 240 and begins to dissolve in the water.

[0037] Subsequently, the control unit 500 reactivates the first pump 120 to supply water from the water storage tank 100 to the electrolytic cell 200. At this time, water is supplied from the supply port 124 toward the supply area 240, and the pressure of the supplied water further promotes the dissolution of the electrolytic accelerator 410. The water supply continues until the full water float 250 detects that the tank is full. As a result, the humidifying tank 300 stores water containing chloride ions in which some or all of the electrolytic accelerator 410 has dissolved, in a full state.

[0038] Figures 3A and 3B show an overview of the operation of the air purification device 1000, following Figures 2A to 2C.

[0039] Figure 3A shows the state following Figure 2C. The control unit 500 generates electrolyzed water by electrolyzing water containing chloride ions by applying current to the electrode unit 210. 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 a second concentration, which is lower than the first concentration, is generated.

[0040] Figure 3B shows the state following Figure 3A. When electrolyzed water of the second concentration is generated, the control unit 500 operates the third pump 220 to supply the electrolyzed water of the second concentration to the humidifying tank 300. At this time, the quantitative measuring cup 224 is used, so the amount of electrolyzed water of the second concentration that is equal to the capacity of the quantitative measuring cup 224 is supplied to the humidifying tank 300. The electrolyzed water of the second concentration is diluted in the humidifying tank 300. The control unit 500 stops the third pump 220 and then operates the purification unit 310 to release the air that has come into contact with the electrolyzed water in the humidifying tank 300 to the outside of the air purification device 1000. In other words, the release of air that has come into contact with the electrolyzed water begins after a time shorter than 40 minutes.

[0041] (3) Normal processing The normal process is a process to release electrolyzed water of the desired concentration. Figures 4A and 4B show an overview of the operation of the air purification device 1000, following Figures 3A and 3B.

[0042] Figure 4A shows the state following Figure 3B. Since some of the electrolyzed water of the second concentration in the electrolytic cell 200 has been supplied to the humidifying tank 300, the electrolytic cell 200 is not full of electrolyzed water of the second concentration. The control unit 500 supplies water from the water storage tank 100 to the electrolytic cell 200 by operating the first pump 120. At this time, water is supplied from the supply port 124 toward the supply area 240, and the pressure of the supplied water further dissolves any undissolved electrolytic accelerator 410. The water supply continues until the full water float 250 detects that the cell is full. As a result, the electrolytic cell 200 becomes full. After the water supply to the electrolytic cell 200 is completed, the control unit 500 generates electrolyzed water by electrolysis by energizing the electrode unit 210. Here, the electrolysis time is set to the time required to generate electrolyzed water of the first concentration (for example, 40 minutes). As a result, electrolyzed water of the first concentration is generated.

[0043] Figure 4B shows the state following Figure 4A. When electrolyzed water of the first concentration is generated, the control unit 500 operates the third pump 220 to supply the electrolyzed water of the first concentration to the humidifying tank 300. At this time, the quantitative measuring cup 224 is used, so the amount of electrolyzed water of the first concentration equal to the capacity of the quantitative measuring cup 224 is supplied to the humidifying tank 300. The electrolyzed water of the first concentration is diluted in the humidifying tank 300. The control unit 500 stops the third pump 220 and then operates the purification unit 310 to release the air that has come into contact with the electrolyzed water in the humidifying tank 300 to the outside of the air purification device 1000.

[0044] When air that has come into contact with electrolyzed water is released, the amount of electrolyzed water in the humidifier tank 300 decreases. When the low water float 360 detects a water shortage, the control unit 500 operates the third pump 220 to supply electrolyzed water of the first concentration to the humidifier tank 300 in an amount equal to the volume of the quantitative measuring cup 224, and operates the second pump 130 to supply water from the water storage tank 100 to the humidifier tank 300 until it is full. This ensures that the release of electrolyzed water continues. This process is repeated until the low water float 260 detects a water shortage.

[0045] (4) Recursion The restart process is performed to re-execute the normal process when the depletion float 260 detects depletion, that is, when the electrolyzed water in the electrolytic cell 200 runs out. After supplying electrolyzed water at a first concentration to the humidification tank 300, if depletion is detected by the depletion float 260, the control unit 500 starts supplying water to the electrolytic cell 200 by the first supply unit 128. In other words, the control unit 500 does not supply water to the electrolytic cell 200 until it runs out of water. This is to maintain the concentration of electrolyzed water in the electrolytic cell 200 at the first concentration by not supplying water. It is also to reduce the amount of impurities such as inorganic salt compounds remaining in the electrolytic cell 200 by making it less likely for old electrolyzed water to remain in the electrolytic cell 200. As a result, the frequency of maintenance of the electrolytic cell 200 is reduced.

[0046] Here, the control unit 500, similar to the initial process, supplies water for a certain period of time, such that the electrolytic cell 200 does not become completely full. Subsequently, the control unit 500 drops the electrolysis accelerator 410 from the inlet 404 towards the supply area 240 of the electrolytic cell 200, and continues to supply water until the electrolytic cell 200 is full. The control unit 500 also generates electrolyzed water of a second concentration by energizing the electrode unit 210, and then supplies this electrolyzed water of a second concentration from the electrolytic cell 200 to the humidifier tank 300. In other words, the same process as part of the initial process is performed. Following this, the normal process is performed.

[0047] (5) Addition of electrolysis accelerator As described above, the electrolytic accelerator input unit 400 adds the electrolytic accelerator 410 to the electrolytic cell 200. Here, the configuration and operation related to the addition of the electrolytic accelerator 410 will be explained.

[0048] Figure 5 is an exploded perspective view of the electrolytic accelerator input unit 400, with a portion of the case 420 cut out to show the inside of the case 420. Figure 6 is a perspective view showing the inside of the case 420 of the electrolytic accelerator input unit 400, and in particular an enlarged perspective view of the hole 440 in the case 420 of the electrolytic accelerator input unit 400 and the notch 434 of the rotating body 424, showing how the electrolytic accelerator 410 falls through the notch 434 of the rotating body 424 and the hole 440 of the case 420.

[0049] As shown in Figures 5 and 6, the electrolytic accelerator input unit 400 includes a case 420, a case cover 422, a rotating body 424, a motor unit 426, a light-emitting unit 450, and a light-receiving unit 452. The case 420 is a deep circular dish with an open top, and a bowl-shaped case cover 422 with an open bottom is detachably attached to the upper end. The case 420 contains a rotating body 424, and the motor unit 426 is located below the case. The motor unit 426 rotates the rotating body 424 within the case 420 with the vertical direction as the axis of rotation. The rotating body 424 corresponds to the tablet input member described above. The bottom surface of the case 420 has a bearing hole 428 and a hole 440. The bearing hole 428 is a hole into which the rotation axis 432 of the rotating body 424, which will be described later, fits. The hole 440 is a hole through which the electrolytic accelerator 410 passes. A guide tube 442 is positioned in the hole 440, extending downward from the opening edge of the hole 440.

[0050] The light-emitting section 450 is located to the side of the hole 440 through which the electrolytic accelerator 410 passes and the guide cylinder 442, and is positioned perpendicular to the direction in which the electrolytic accelerator 410 passes. The light-emitting section 450 is composed of, for example, an infrared LED (Light Emitting Diode) and is arranged to emit light toward the passage position of the electrolytic accelerator 410.

[0051] The light-receiving unit 452 is positioned to the side of the guide cylinder 442 and the hole 440 through which the electrolytic accelerator 410 passes, and is facing the light-emitting unit 450 across the hole 440. The light-receiving surface of the light-receiving unit 452 is positioned facing the passage position of the electrolytic accelerator 410, and it is capable of receiving light from the light-emitting unit 450. When the light-receiving unit 452 receives light from the light-emitting unit 450, it outputs a signal according to the intensity of the received light. As one aspect of the output signal of the light-receiving unit 452, for example, when the light is blocked by the passage of the electrolytic accelerator 410, i.e., when the intensity of the received light decreases, the signal intensity decreases.

[0052] The rotating body 424 has a convex portion 430 which is a disc with a central part that is convex upward, and a cylindrical rotating shaft 432 which extends downward from the central lower surface of the convex portion 430. The convex portion 430 and the rotating shaft 432 are integrally formed from a resin material. The size of the convex portion 430 is slightly smaller than the case 420, and there is a small gap between the outer circumference of the convex portion 430 and the inner surface of the case 420. A notch 434 is positioned on the periphery of the convex portion 430. The electrolytic accelerator 410 enters this notch 434, and when it aligns with the hole 440, the electrolytic accelerator 410 is introduced into the electrolytic cell 200.

[0053] In this configuration, even if the control unit 500 instructs the electrolytic accelerator input unit 400 to input the electrolytic accelerator 410, there are rare cases where the intensity of light received by the light receiving unit 452 decreases, meaning that the passage of the electrolytic accelerator 410 is not detected. This situation occurs for the following two reasons. The first reason is that the electrolytic accelerator 410 is dropped into the electrolytic cell 200 by passing through the notch 434 and the hole 440, but the decrease in the intensity of light received by the light receiving unit 452 is small. This is a false detection by the light receiving unit 452. The second reason is that even if the notch 434 and the hole 440 overlap due to the rotation of the rotating body 424, the electrolytic accelerator 410 does not pass through the notch 434 and the hole 440 and is not dropped into the electrolytic cell 200. This occurs, for example, when the electrolytic accelerator 410 is dissolving and is adhering to the wall surface of the notch 434. Furthermore, if the electrolytic accelerator 410 is repeatedly added to the electrolytic accelerator input unit 400 and the electrolytic accelerator 410 in the electrolytic accelerator input unit 400 runs out, the passage of the electrolytic accelerator 410 may not be detected.

[0054] As described above, in such a situation, the instruction to add the electrolytic accelerator 410 is given again. As a result, especially in the case of the first cause, more electrolytic accelerator 410 than the predetermined number is added, and electrolyzed water with a hypochlorous acid concentration higher than the standard value is produced. In order to prevent the hypochlorous acid concentration in the electrolyzed water from exceeding the standard value, the air purification device 1000 according to this embodiment performs the following process.

[0055] Figure 7 shows the functional blocks of the air purification device 1000. The air purification device 1000 includes a light-emitting unit 450, a light-receiving unit 452, an electrolytic water generation unit 460, a control unit 500, and a notification unit 530. The electrolytic water generation unit 460 includes an electrode unit 210 and an electrolytic accelerator input unit 400. The control unit 500 includes an input instruction unit 510, an input detection unit 512, a non-input detection count unit 514, and an energization processing unit 520, and the energization processing unit 520 includes an energization setting determination unit 522.

[0056] The input instruction unit 510 instructs the electrolytic accelerator input unit 400 to input the electrolytic accelerator 410. The timing of the input instruction unit 510's instruction to input the electrolytic accelerator 410 is as described above. The input instruction unit 510 instructs the input of the electrolytic accelerator 410, instructs the light-emitting unit 450 to emit light, and notifies the non-input detection count unit 514 of the instruction to input the electrolytic accelerator 410.

[0057] The input detection unit 512 detects whether the electrolytic accelerator 410 has passed through the hole 440, that is, whether the electrolytic accelerator 410 has been added, based on the signal from the light receiving unit 452. For example, the input detection unit 512 determines that the electrolytic accelerator 410 has passed through the hole 440 if the intensity of the received light is lower than a threshold, and determines that the electrolytic accelerator 410 has not passed through the hole 440 if the intensity of the received light is equal to or greater than the threshold. The threshold is set in advance, for example, by simulation or experiment. Therefore, the phrase "based on the signal from the light receiving unit 452" above means signal attenuation, that is, a decrease in light intensity. The input detection unit 512 outputs the detection result to the input instruction unit 510, the non-input detection count unit 514, and the power supply processing unit 520.

[0058] If the detection result received from the input detection unit 512 does not indicate the input of the electrolytic accelerator 410, the input instruction unit 510 repeats the process described above. Specifically, the input instruction unit 510 instructs the electrolytic accelerator input unit 400 to input the electrolytic accelerator 410, instructs the light-emitting unit 450 to emit light, and notifies the non-input detection count unit 514 of the instruction to input the electrolytic accelerator 410. This process is repeated until the input detection unit 512 detects the input of the electrolytic accelerator 410. As described later, an upper limit may be set on the number of repetitions.

[0059] The non-addition detection count unit 514 receives instructions to add the electrolytic accelerator 410 from the addition instruction unit 510 and also receives detection results from the addition detection unit 512. The non-addition detection count unit 514 counts the number of times the addition of the electrolytic accelerator 410 was instructed by the addition instruction unit 510, but the addition detection unit 512 did not detect the addition of the electrolytic accelerator 410. This number is the "non-addition detection count". The non-addition detection count is reset when the detection result received from the addition detection unit 512 indicates the addition of the electrolytic accelerator 410, or when the number of repetitions of the addition instruction in the addition instruction unit 510 reaches the upper limit.

[0060] The power supply setting determination unit 522 receives the number of non-insertion detections from the non-insertion detection count unit 514. Based on the number of non-insertion detections, the power supply setting determination unit 522 determines the power supply setting for electrolysis in the electrolytic water generation unit 460. For example, the power supply setting is the setting of the power supply time, and the power supply setting determination unit 522 shortens the power supply time the more non-insertion detections there are. Specifically, the power supply setting determination unit 522 determines the power supply time by a specified value of the power supply time (hereinafter referred to as "specified time") / (1 + number of non-insertion detections). An example of the specified time is the aforementioned "40 minutes". Therefore, if the input detection unit 512 does not fail to detect input, the power supply time is set to the specified time.

[0061] Figure 8 shows an overview of the processing in the power setting determination unit 522. Here, we assume cases "1" to "6". Cases "1" to "3" correspond to the first cause mentioned above. Cases "4" to "6" correspond to the second cause mentioned above. In case "1", when the input instruction unit 510 instructs the initial input, the electrolytic accelerator input unit 400 successfully inputs, but the input detection unit 512 fails to detect. Subsequently, when the input instruction unit 510 instructs the first retry input, the electrolytic 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 electrolytic accelerators 410 added is "2". The power setting determination unit 522 determines the power supply time to "1 / 2" of the specified time.

[0062] In case "2", when the input instruction unit 510 instructs the initial input, the electrolytic accelerator input unit 400 successfully inputs the agent, but the input detection unit 512 fails to detect it. The same occurs on the first retry. When the input instruction unit 510 instructs the second retry input, the electrolytic accelerator input unit 400 successfully inputs the agent, and the input detection unit 512 also successfully detects it. As a result, the number of times the agent was not detected is "2", and the number of electrolytic accelerators 410 that were input is "3". The power setting determination unit 522 determines the power-on time to "1 / 3" of the specified time.

[0063] In case "3", when the input instruction unit 510 instructs the initial input, the electrolytic accelerator input unit 400 successfully inputs the agent, but the input detection unit 512 fails to detect it. The same is true for the first and second retries. When the input instruction unit 510 instructs the third retry input, the electrolytic accelerator input unit 400 successfully inputs the agent, and the input detection unit 512 also successfully detects it. As a result, the number of times the agent was not detected is "3", and the number of electrolytic accelerators 410 that were input is "4". The power setting determination unit 522 determines the power-on time to "1 / 4" of the specified time.

[0064] In case "4", when the input instruction unit 510 instructs the initial input, the electrolytic accelerator input unit 400 fails to input, and the input detection unit 512 fails to detect. Subsequently, when the input instruction unit 510 instructs the first retry input, the electrolytic accelerator input unit 400 succeeds in input, and the input detection unit 512 also succeeds in detection. As a result, the number of non-input detections is "1", and the number of electrolytic accelerators 410 added is "1". The power setting determination unit 522 determines the power supply time to "1 / 2" of the specified time.

[0065] In case "5", when the input instruction unit 510 instructs the initial input, the electrolytic accelerator input unit 400 fails to input, and the input detection unit 512 fails to detect. The same occurs on the first retry. When the input instruction unit 510 instructs the second retry input, the electrolytic accelerator input unit 400 succeeds in input, and the input detection unit 512 also succeeds in detection. As a result, the number of times input was not detected is "2", and the number of electrolytic accelerators 410 that were input is "1". The power setting determination unit 522 determines the power-on time to "1 / 3" of the specified time.

[0066] In case "6", when the input instruction unit 510 instructs the initial input, the electrolytic accelerator input unit 400 fails to input, and the input detection unit 512 fails to detect. The same occurs in the first and second retries. When the input instruction unit 510 instructs the third retry input, the electrolytic accelerator input unit 400 succeeds in input, and the input detection unit 512 also succeeds in detection. As a result, the number of times input was not detected is "3", and the number of electrolytic accelerators 410 that were input is "1". The power setting determination unit 522 determines the power-on time to "1 / 4" of the specified time.

[0067] In cases "1" through "3", the number of electrolytic accelerators 410 added is greater than the predetermined number of "1". However, since the energizing time is shorter than the specified time, the concentration of hypochlorous acid in the electrolyzed water is prevented from exceeding the standard value. On the other hand, in cases "4" through "6", the number of electrolytic accelerators 410 added is the predetermined number of "1". Furthermore, since the energizing time is shorter than the specified time, the concentration of hypochlorous acid in the electrolyzed water is lower, but it does not exceed the standard value, thus ensuring safety.

[0068] The energization processing unit 520 energizes the electrode unit 210 according to the energization time set by the energization setting determination unit 522 after the input detection unit 512 detects the addition of the electrolytic accelerator 410. In response, the electrolytic water generation unit 460 generates electrolytic water according to the energization setting after the input detection unit 512 detects the addition of the electrolytic accelerator 410.

[0069] The input instruction unit 510 does not instruct the electrolytic accelerator input unit 400 to input the electrolytic accelerator 410 if the number of non-input detection counts counted by the non-input detection count unit 514 exceeds a threshold. The threshold is, for example, "4". The notification unit 530 notifies the electrolytic accelerator input unit 400 of an input error when the number of non-input detection counts exceeds the threshold.

[0070] The subject of the apparatus, system, or method in this disclosure comprises a computer. The functions of the subject of the apparatus, system, or method in this disclosure are realized by the computer executing a program. The computer comprises a processor as its main hardware component, which operates according to the program. The processor is of any type as long as it can realize its functions by executing the program.

[0071] The operation of the air purification device 1000 with the above configuration will now be explained. Figure 9 is a flowchart showing the control procedure by the air purification device 1000.

[0072] First, water is supplied to the water tank 100 from an external source (S10).

[0073] Next, water is supplied from the water storage tank 100 to the electrolytic cell 200 in an amount less than the full capacity of the electrolytic cell 200 (S12).

[0074] Next, the electrolytic accelerator 410 is supplied from the electrolytic accelerator input unit 400 to the electrolytic cell 200 (S14).

[0075] Next, water is supplied from the water storage tank 100 to the electrolytic cell 200 until the electrolytic cell 200 is full (S16).

[0076] Next, the electrode unit 210 performs electrolysis for 10 minutes (S18). This generates electrolyzed water of a second concentration in the electrolytic cell 200.

[0077] Next, electrolyzed water of the second concentration is supplied from the electrolytic cell 200 to the humidifying tank 300 (S20). This causes the electrolyzed water to be released from the humidifying tank 300.

[0078] Next, water is supplied from the water storage tank 100 to the electrolytic cell 200 until the electrolytic cell 200 is full (S22).

[0079] Next, the electrode unit 210 performs electrolysis for 40 minutes (S24). This generates electrolyzed water of the first concentration in the electrolytic cell 200.

[0080] Next, electrolyzed water of the first concentration is supplied from the electrolytic cell 200 to the humidifying tank 300 (S26).

[0081] Next, the purification unit 310 releases electrolyzed water (S28).

[0082] Next, the drought float 360 determines whether the humidifier tank 300 is running low on water (S30). If it is determined in step S30 that the humidifier tank 300 is not running low on water (N in S30), the process returns to step S28.

[0083] If the humidifier tank 300 is determined to be depleted of water in step S30 (Y in S30), the depletion float 260 determines whether the electrolytic cell 200 is depleted of water or not (S32). If the electrolytic cell 200 is determined to not be depleted of water in step S32 (N in S32), the process returns to step S26.

[0084] If the electrolytic cell 200 is determined to be low on water in step S32 (Y in S32), the process returns to step S12.

[0085] Figure 10 is a flowchart showing the procedure for energizing the air purification device 1000.

[0086] First, the non-insertion detection count unit 514 sets the non-insertion detection count to 0 (S50).

[0087] Next, the input instruction unit 510 instructs the electrolytic accelerator input unit 400 to input the electrolytic accelerator 410 (S52).

[0088] Next, the input detection unit 512 determines whether or not it has detected the input of the electrolytic accelerator 410 (S54). If the input detection unit 512 detects the input of the electrolytic accelerator 410 in step S54 (Y in S54), the power setting determination unit 522 determines the power setting based on the number of times the input was not detected (S56). After that, the electrolytic water generation unit 460 generates electrolytic water according to the power setting (S58).

[0089] If the input detection unit 512 does not detect the input of the electrolytic accelerator 410 in step S54 (N in S54), the non-input detection count unit 514 adds "1" to the non-input detection count (S60). Then, the non-input detection count unit 514 determines whether the non-input detection count is "4" or not (S62).

[0090] If it is determined in step S62 that the number of non-insertion detections is not "4" (N in S62), the process returns to step S52.

[0091] If the number of non-insertion detections in step S62 is determined to be "4" (Y in S62), the notification unit 530 notifies of an insertion error (S64).

[0092] According to this embodiment, the power supply setting is determined based on the counted number of times non-input detections have occurred, so even if false detections occur, a power supply setting that includes false detections can be determined. Furthermore, even if false detections occur, a power supply setting that includes false detections can be determined, so it is possible to suppress the concentration of hypochlorous acid in the electrolyzed water from exceeding the standard value. In addition, since it is suppressed that the concentration of hypochlorous acid in the electrolyzed water will not exceed the standard value, safety can be ensured. Furthermore, the device instructs the addition of the electrolysis accelerator 410 until its addition is detected, and after the addition of the electrolysis accelerator 410 is detected, the device generates electrolyzed water according to the power supply setting, so electrolyzed water can be reliably generated.

[0093] Furthermore, the more times the non-addition detection occurs, the shorter the power supply time is, so even if a large amount of electrolytic accelerator 410 is added, the increase in the concentration of hypochlorous acid in the electrolyzed water can be suppressed. Also, if the number of non-addition detections exceeds a threshold, the device does not instruct the addition of the electrolytic accelerator 410, so the operation of the air purification device 1000 can be stopped when there is a risk of malfunction. In addition, if the number of non-addition detections exceeds a threshold, an addition error is notified, so it is possible to notify the user of the occurrence of trouble. Also, if the number of non-addition detections exceeds a threshold, an addition error is notified, so it is possible to notify the user that the electrolytic accelerator 410 in the electrolytic accelerator addition unit 400 has run out.

[0094] Furthermore, since the water treatment tank is divided into a water storage tank 100, an electrolytic cell 200, and a humidifying tank 300, the occurrence of gas-liquid contact between the electrode unit 210 and the water in the electrolytic cell 200 can be suppressed. Also, since the occurrence of gas-liquid contact between the electrode unit 210 and the water in the electrolytic cell 200 is suppressed, the water in the electrolytic cell 200 can be made less prone to contamination. Also, since the water in the electrolytic cell 200 is made less prone to contamination, the deterioration of the electrodes can be suppressed. In addition, since electrolyzed water of the second concentration is supplied to and released from the humidifying tank 300, the time until electrolyzed water is released can be shortened. Also, since electrolyzed water of the first concentration is generated following the electrolyzed water of the second concentration, electrolyzed water of the desired concentration can be released. Also, since the electrolytic accelerator 410 is introduced toward the supply area 240 and water is supplied toward the supply area 240, the dissolution of the electrolytic accelerator 410 can be promoted by the water pressure. Also, since electrolyzed water of the first concentration is generated by normal processing after water is supplied to the electrolytic cell 200, the electrolytic accelerator 410 can be made more soluble.

[0095] Furthermore, when a water shortage is detected, the first supply unit 128 supplies water to the electrolytic cell 200, thus eliminating the need to supply water until a water shortage is detected. Also, since water supply is not required until a water shortage is detected, the concentration of electrolyzed water in the electrolytic cell 200 can be maintained. In addition, since water supply is not required until a water shortage is detected, impurities remaining in the electrolytic cell 200 can be flushed out. Part of the initial processing is performed as a restart process, which simplifies the operation.

[0096] An outline of one aspect of the present disclosure is as follows: An air purification device (1000) in one aspect of the present disclosure includes an electrolytic cell (200) for storing water and electrolyzed water, an electrolytic accelerator input unit (400) for introducing an electrolytic accelerator (410) into the electrolytic cell (200), an electrolyzed water generation unit (460) for electrolyzing the water into which the electrolytic accelerator (410) has been introduced to produce electrolyzed water, a purification unit (310) for bringing the electrolyzed water generated by the electrolyzed water generation unit (460) into contact with air drawn in from an air intake, an input instruction unit (510) for instructing the electrolytic accelerator input unit (400) to introduce the electrolytic accelerator (410), and the electrolytic accelerator input unit (400 The system includes: an input detection unit (512) that detects the input of an electrolytic accelerator (410) by an input instruction unit (510); a non-input detection count unit (514) that counts the number of times the input detection unit (512) failed to detect the input of the electrolytic accelerator (410) despite the input instruction unit (510) instructing the input of the electrolytic accelerator (410); and a power setting determination unit (522) that determines the power setting for electrolysis in the electrolytic water generation unit (460) based on the number of non-input detections counted by the non-input detection count unit (514).

[0097] The input instruction unit (510) instructs the electrolytic accelerator input unit (400) to input the electrolytic accelerator (410) until the input detection unit (512) detects the input of the electrolytic accelerator (410). The electrolytic water generation unit (460) may generate electrolytic water by setting the power supply after the input detection unit (512) detects the input of the electrolytic accelerator (410).

[0098] The power supply setting may include setting the power supply time in the electrolytic water generation unit (460). The power supply setting determination unit (522) may shorten the power supply time as the number of non-insertion detections increases.

[0099] The power supply setting may include setting the current value in the electrolytic water generation unit (460). The power supply setting determination unit (522) may decrease the current value as the number of non-charge detections increases.

[0100] The power supply setting may include setting the power supply voltage value in the electrolytic water generation unit (460). The power supply setting determination unit (522) may decrease the power supply voltage value as the number of non-charge detections increases.

[0101] The input instruction unit (510) does not need to instruct the electrolytic accelerator input unit (400) to input the electrolytic accelerator (410) if the number of times non-input detections exceeds a threshold.

[0102] The system may further include a notification unit (530) that notifies the electrolytic accelerator dispenser (400) of an dispenser error when the number of non-dispensing detections exceeds a threshold.

[0103] The present disclosure has been described above based on embodiments. These embodiments are illustrative, and it will be understood by those skilled in the art that various modifications are possible for each component or combination of processing processes, and that such modifications are also within the scope of the present disclosure.

[0104] In this embodiment, the power supply setting determination unit 522 sets the power supply time as the power supply setting. However, it is not limited to this, and for example, the power supply setting determination unit 522 may set the power supply current value as the power supply setting. In this case, the power supply setting determination unit 522 decreases the power supply current value as the number of non-power supply detections increases. Alternatively, the power supply setting determination unit 522 may set the power supply voltage value as the power supply setting. In this case, the power supply setting determination unit 522 decreases the power supply voltage value as the number of non-power supply detections increases. This modified example improves the degree of freedom in configuration.

[0105] The air purification device 1000 in this embodiment comprises an electrolytic cell 200 and a humidifying tank 300. However, it is not limited to this configuration; for example, the electrolytic cell 200 and the humidifying tank 300 may be integrated as a water storage unit. This modified configuration simplifies the structure of the air purification device 1000.

[0106] In this embodiment, the water shortage float 260 detects water shortage based on the position of the magnet on the float. However, it is not limited to this; for example, water shortage may be detected based on the number of times electrolyzed water has been supplied from the quantitative tank 224. For example, if the electrolytic cell 200 has a capacity of 1000 ml and the quantitative tank 224 has a capacity of 250 ml, water shortage will be detected when electrolyzed water has been supplied from the quantitative tank 224 four times. This modified example increases the degree of freedom in configuration.

[0107] In this embodiment, water or electrolyzed water is supplied when a water shortage is detected. However, this is not limited to this, for example, the next supply of water or electrolyzed water may be made after a certain period of time has elapsed since the previous supply. This modified example increases the degree of freedom in the configuration.

[0108] Furthermore, the control unit 500 may also include a memory unit for storing the currently executing control content. An example of a memory unit is a non-volatile memory. The control unit 500 periodically stores the currently executing control content in the memory unit as needed. If the power supply to the air purification device 1000 is interrupted and then restored, the control unit 500 may control the air purification device 1000 based on the currently executing control content stored in the memory unit. In other words, if the power supply to the air purification device 1000 is interrupted and then restored, the control unit 500 may resume from the control content that was being executed and stored in the memory unit. This ensures that the correct control content can be performed even if the power supply to the air purification device 1000 is interrupted and then restored. [Explanation of symbols]
