Disclosure of Invention

In order to generate hypochlorous acid, water to be electrolyzed is electrolyzed. Therefore, it is necessary to charge an electrolysis accelerator such as a salt to generate water containing chlorine ions. However, if the electrolysis is continued, inorganic salts such as calcium carbonate, calcium sulfate, and silica contained in the water may be attached to the water storage tank as impurities, and the original product performance (electrolysis performance) may not be maintained.

In order to maintain the product performance, it is necessary to urge the user to periodically clean the water storage tank and the like from the electrolytic water spray device. In the conventional electrolytic water spraying device, it is difficult to determine whether the water storage tank or the like is contaminated. Therefore, in the conventional electrolytic water spraying device, maintenance for cleaning regularly is urged regardless of the dirt on the water storage tank or the like.

The invention aims to provide an electrolytic water spraying device capable of informing the accurate cleaning time.

The electrolytic water spraying apparatus according to the present invention comprises: a main body case provided with an air suction port and an air outlet; a water storage part for storing water; an electrode unit for electrolyzing water in the water storage unit to generate electrolyzed water; a spraying part which is provided with an air inlet and an air outlet and sprays the generated electrolyzed water from the air outlet while making the electrolyzed water contact with the air sucked from the air inlet; and a control section that controls the electrode section and the spraying section. The control unit includes: an index calculation unit that calculates an index of the electrolysis efficiency with respect to a predetermined reference, based on a relationship between a voltage applied to the electrode unit and a current flowing through the electrode unit; and a determination unit for determining the cleanliness of the water in the water storage unit based on the index calculated by the index calculation unit.

According to the present invention, it is possible to provide an electrolytic water sprinkler capable of notifying an accurate cleaning time.

(embodiment mode 1)

First, an electrolytic water spraying device D according to embodiment 1 of the present invention will be described.

Fig. 1 is a perspective view of an electrolytic water sprinkler D. Fig. 2 is a perspective view of the electrolyzed water spraying apparatus D in a state where the panel 3 of fig. 1 is opened.

As shown in fig. 1 and 2, the electrolyzed water spraying apparatus D includes a main body case 1.

The main body case 1 is a box-shaped body having an approximately box shape, and includes an air inlet 2, an air outlet 6, a panel 3, and a cleaning display unit 26.

The air inlets 2 are provided on both side surfaces of the main body case 1, and are lattice-shaped openings for introducing air outside the main body case 1 into the main body case 1.

The air outlet 6 is provided on the back side of the top surface of the body casing 1. The air outlet 6 is an opening/closing type opening for blowing out the air introduced into the main body casing 1 from the air inlet 2 to the outside of the main body casing 1. In fig. 1 and 2, air outlet 6 is in a closed state.

The panel 3 is provided on the side on the right side in the front view of the body case 1, that is, the body side 1A. The panel 3 is an openable and closable cover, and is mainly formed of plastic resin. One of the two air inlets 2 is provided on the front surface side of the main body case 1 of the panel 3. An opening 4 is provided inside the panel 3.

The opening 4 is a hole extending horizontally from the vertically long quadrangular opening on the right side surface (main body side surface 1A) in the main body case 1 to the left side. An electrolyzed water production section 5 and a water supply section 15 are provided in the opening 4. Details of the electrolyzed water forming section 5 and the water supply section 15 will be described later.

The cleaning display unit 26 is provided on the top surface of the main body case 1, and displays a display for urging the user to perform cleaning work of at least one of the water storage unit 14 and the filter unit 16 (see fig. 4). The cleaning display unit 26 is, for example, an LED (light emitting diode), and the user is urged to clean by lighting the LED.

As shown in fig. 2, the electrolyzed water spraying apparatus D includes a control section 20.

The controller 20 controls the electrolytic water sprinkler D. The control of the control unit 20 will be described later.

FIG. 3 isbase:Sub>A sectional view taken on the plane A-A of the electrolytic water sprinkler D of FIG. 2, and isbase:Sub>A view of the electrolytic water sprinkler D as seen from the right side. Fig. 3 shows the peripheral structure of the electrolyzed water generation.

As shown in FIGS. 2 and 3, the electrolyzed water forming apparatus 5 includes a water storage portion 14, an electrode portion 17, and an electrolysis accelerator introduction portion 25.

The water storage portion 14 has a box shape with an open top surface, and is configured to store water supplied from the water supply portion 15. The water reservoir 14 is disposed at a lower portion of the main body case 1, and is slidable in the horizontal direction with respect to the main body case 1 so as to be attachable to and detachable from the opening 4. Water storage unit 14 includes tank holding unit 14a and water level detection unit 18.

The tank holding portion 14a is provided on the bottom surface of the water storage portion 14. A water supply unit 15 is attached to an upper portion of the tank holding unit 14 a.

Water level detector 18 detects the water level of water storage unit 14. The water level detector 18 is composed of, for example, a magnet with a float having a buoyancy inside, and a magnetic force detector provided at a position facing the magnet with the float and detecting a magnetic force of the magnet. However, the water level detector 18 is not limited to this configuration as long as it can detect the water level.

The electrode portion 17 includes an electrode member provided so as to be immersed in the water storage portion 14. The electrode portion 17 electrochemically electrolyzes the water containing chlorine ions in the water storage portion 14, that is, the electrolyzed water, by energizing the electrode member, to generate electrolyzed water containing active oxygen species. The reactive oxygen species include so-called broad reactive oxygen species such as superoxide anion, singlet oxygen, hydroxyl radical, and hydrogen peroxide.

The electrode portion 17 generates electrolyzed water by repeating one cycle of an energization time during which the electrode member is energized for electrolysis and a non-energization time which is a time after the energization is stopped, i.e., a time during which the energization is not performed. That is, by providing the non-energization time to the electrode member, the life of the electrode member can be extended. In addition, if the energization time is extended with respect to the non-energization time, electrolytic water containing a larger number of active oxygen species is generated in one cycle. In addition, if the non-energization time is extended with respect to the energization time, the generation of reactive oxygen species per one cycle can be suppressed. Further, if the amount of electricity in the energization time is increased, electrolytic water containing more active oxygen species is generated.

The electrolysis accelerator feeding section 25 includes a tablet feeding cassette 25a and a tablet feeding cover 25b.

The tablet charging box 25a is a box that houses an electrolysis accelerator for charging into the water storage part 14, and can be taken out from the opening 4.

The tablet input cover 25b is a cover that is detachably provided on the upper portion of the tablet input case 25 a. The user can store the electrolytic accelerator in the tablet insertion case 25a by removing the tablet insertion cover 25b.

When the electrolytic accelerating agent is charged into the water storage part 14, the electrolytic accelerating agent charging part 25 rotates a tablet charging member (not shown) provided in the tablet charging cassette 25 a. When the tablet input member is rotated, the electrolytic acceleration agent falls into the water storage portion 14 from a falling opening (not shown) in the bottom surface of the tablet input case 25 a.

The electrolytic accelerating agent charging part 25 counts the number of electrolytic accelerating tablets falling from the tablet charging box 25a into the water storage part 14. If the electrolysis promoting agent charging part 25 determines that one electrolysis promoting tablet falls into the water storage part 14 from the tablet charging box 25a, the rotation of the tablet charging member is stopped. Next, the electrolysis accelerator is dissolved in the water storage portion 14, thereby generating water containing chlorine ions. Sodium chloride is an example of the electrolysis accelerator.

Water supply unit 15 is disposed above water storage unit 14. Water supply unit 15 is configured to be attachable to and detachable from water storage unit 14, and is removable from opening 4. The water supply part 15 includes a tank 15a and a cover 15b.

The tank 15a is a hollow container for storing water.

The cover 15b is provided at an opening at a lower portion of the can 15 a. An opening/closing portion (not shown) is provided in the center of the cover 15b. When the opening/closing unit is opened, water in the tank 15a is supplied to the water storage unit 14. Specifically, if the opening of the tank 15a is directed downward and the water supply unit 15 is attached to the tank holding unit 14a of the water storage unit 14, the opening/closing unit is opened by the tank holding unit 14 a. That is, if water is supplied to water supply unit 15 and attached to tank holding unit 14a, the opening/closing unit is opened to supply water to water storage unit 14, and the water is stored in water storage unit 14.

If the water level in the water storage portion 14 rises and reaches the position of the cover 15b, the opening of the water supply portion 15 is sealed with water. Therefore, water supply from water supply unit 15 to water storage unit 14 is stopped, and water remains in water supply unit 15. When the water level in water storage unit 14 drops, water in tank 15a is supplied to water storage unit 14 every time. That is, the water level in the water storage portion 14 is kept constant.

FIG. 4 is a sectional view in the plane B-B of the electrolytic water sprinkler D of FIG. 2, as seen from the right side. FIG. 4 shows an air passage structure of the electrolytic water sprinkler D.

As shown in fig. 4, the main body case 1 is provided with a sprinkler 19 and an air passage 8.

The spraying section 19 includes the air blowing section 7 and the filter section 16.

The air blowing unit 7 is provided in the center of the main body case 1, and includes a motor unit 9, a fan unit 10, and a case unit 11.

The motor unit 9 is, for example, a dc motor, and is fixed to the housing 11.

The fan unit 10 is, for example, a sirocco fan, and is rotated by the power of the motor unit 9. The fan unit 10 is fixed to a rotating shaft 9a extending in the horizontal direction from the motor unit 9. The rotation shaft 9a of the motor unit 9 extends from the front side to the rear side in the main body case 1.

The casing 11 surrounds the motor 9 and the fan 10 and has a scroll shape. The housing portion 11 includes an intake port 13 and an exhaust port 12.

The suction port 13 is provided on the back side of the main body case 1 of the case portion 11, and is an opening for introducing air sucked into the main body case 1 through the suction port 2 into the case portion 11.

The outlet 12 is provided on the upper surface side of the body case 1 of the case portion 11, and is an opening for discharging the air introduced into the case portion 11 from the inlet 13 to the outside of the case portion 11.

The filter unit 16 is a cylindrical member that brings the electrolyzed water stored in the water storage unit 14 into contact with the indoor air that has flowed into the main body case 1 by the air blowing unit 7. The filter portion 16 includes a gas-liquid contact filter portion 16a.

The gas-liquid contact filter unit 16a is disposed in a circumferential portion of the filter unit 16, and is provided with holes through which air can flow.

One end of the filter unit 16 is disposed so as to be immersed in water in the water storage unit 14 and retain the water. The filter unit 16 is rotated by a driving unit (not shown) around the central axis of the gas-liquid contact filter unit 16a. Thereby, the filter unit 16 has a structure in which the electrolyzed water and the air are continuously brought into contact with each other.

Air passage 8 communicates air inlet 2 and air outlet 6. The air passage 8 includes a filter unit 16, an air blower 7, and an air outlet 6 in this order from the air inlet 2 to the downstream side. When the fan unit 10 is rotated by the control of the motor unit 9 by the controller 20, the air taken in from the air inlet 2 and taken into the air duct 8 from the outside is blown out to the outside of the electrolytic water spraying device D through the gas-liquid contact filter unit 16a, the blowing unit 7, and the blowing port 6 in this order. Thereby, the electrolyzed water generated in the water storage portion 14 is sprayed to the outside. The electrolyzed water spraying apparatus D may not necessarily spray the electrolyzed water itself, and may also spray the finally generated active oxygen species (including volatilized active oxygen species) from the electrolyzed water.

Next, each function of the control unit 20 according to embodiment 1 of the present invention will be described with reference to fig. 5. Fig. 5 is a schematic functional block diagram of the control unit 20 and the peripheral portion of the electrolytic water spraying device D.

The control unit 20 includes an index calculation unit 21, a storage unit 22, a determination unit 23, and a cleaning control unit 24.

The index calculation unit 21 calculates an index of the electrolysis efficiency with respect to a predetermined reference based on the relationship between the voltage and the current applied to the electrode unit 17.

Here, an index of the electrolytic efficiency will be described. The index calculation unit 21 calculates the resistance value of water as the ratio of the voltage value, which is the value of the voltage applied to the electrode portion 17, to the current value, which is the value of the current flowing through the electrode portion 17, after supplying water to the water storage portion 14, and sets the calculated resistance value as the reference resistance value. After the reference resistance value is calculated, the index calculation unit 21 calculates the resistance value of water, which is the ratio of the voltage value applied to the electrode portion 17 to the current value flowing through the electrode portion 17, as a new resistance value, every time water in the water storage portion 14 is drained and new water is supplied to the water storage portion 14.

Specifically, the index calculation unit 21 calculates the resistance value of water by dividing the voltage value by the current value as the ratio of the voltage value to the current value. The resistance value of the water in water reservoir 14 changes according to the ratio of pure water to impurities present in the water stored in water reservoir 14. The impurities mentioned here include not only inorganic salts such as calcium carbonate, calcium sulfate, or silica, but also sodium ions generated from an electrolysis accelerator required for electrolysis. Specifically, the smaller the ratio of impurities to pure water, the higher the resistance value of water in the water reservoir 14. Conversely, the higher the ratio of impurities to pure water, the lower the resistance value of water in the water storage portion 14. That is, the control unit 20 can grasp the state of water from the resistance value of water in the water storage unit 14.

The index calculation unit 21 calculates the reference resistance value and the new resistance value, and then calculates the rate of change of the new resistance value with respect to the reference resistance value. The rate of change of the new resistance value with respect to the reference resistance value is an index regarding the electrolysis efficiency. That is, a large change rate means that the new resistance value is higher than the reference resistance value, and the electrolysis efficiency is reduced. Conversely, a small rate of change means that the new resistance value is lower than the reference resistance value, and the electrolysis efficiency is improved.

Here, the drainage of water in the water storage portion 14 and the necessity of supplying fresh water to the water storage portion 14 after the drainage will be described. The generation of the electrolyzed water containing active oxygen species electrolyzes the water in the water storage portion 14 as the object of electrolysis. Therefore, it is necessary to put an electrolysis accelerator into the water storage part 14 to generate water containing chlorine ions. However, since the electrolysis of the electrode portion 17 is continued, inorganic salts contained in the water adhere to the electrode portion 17 where the electrolysis is performed as impurities. This may shorten the life of the electrode portion 17.

Therefore, after periodically discharging the water to be electrolyzed and supplying new water, it is necessary to newly charge the electrolysis accelerator for electrolysis. This can suppress the reduction in the life of the electrode portion 17. That is, the draining means discarding the water in the water storage portion 14. The water supply is directed to supply fresh water into the water reservoir 14. In order to suppress the reduction in the life of the electrode portion 17, the user needs to periodically perform a water discharge operation and a water supply operation after the water discharge.

Further, the reference resistance value calculated by index calculating unit 21 after water is supplied to water storage unit 14 and the new resistance value calculated after water in water storage unit 14 is discharged and new water is supplied to water storage unit 14 are both after the new water is supplied, but the new resistance value is lower than the reference resistance value. This is because, every time the user performs the drainage work, impurities that cannot be removed in the drainage work are accumulated in the water storage unit 14, the filter unit 16, and the like. If fresh water is supplied to the water storage portion 14, the accumulated impurities are dissolved in the water storage portion 14. This increases the proportion of impurities to the pure water in the reservoir portion 14, and therefore the new resistance value is lower than the reference resistance value. That is, the new resistance value is decreased every time the user performs the water discharge work and the water supply work after the water discharge.

The storage unit 22 is a so-called memory and stores a reference resistance value. The storage unit 22 also stores a predetermined reference. The predetermined criterion is a change threshold value which is a change rate of the resistance value for comparison of the change rate used when the determination unit 23 described later determines the cleanliness of water. The variation threshold is a value predetermined by an experiment or the like, for example, and can be set arbitrarily.

The determination unit 23 determines the cleanliness of the water in the water storage unit 14 based on the index calculated by the index calculation unit 21. Specifically, when the change rate calculated by the index calculation unit 21 is smaller than the change threshold stored in the storage unit 22, the determination unit 23 determines that the cleanliness of water is low. Further, when the change rate calculated by the index calculation unit 21 is equal to or greater than the change threshold stored in the storage unit 22, the determination unit 23 determines that the cleanliness of water is high.

As described above, the new resistance value decreases every time the user performs the water discharge work and the water supply work after the water discharge. That is, the change rate calculated by the index calculation unit 21 decreases every time the user performs the water discharge operation and the water supply operation after the water discharge. This is because, every time the user performs the drainage work, impurities that cannot be removed in the drainage work are accumulated in the water storage unit 14, the filter unit 16, and the like. In the case where the change rate decreases every time the user performs the water discharge operation and the water supply operation after the water discharge, the user repeats the water discharge operation and the water supply operation after the water discharge so that the change rates of both are smaller than the change threshold. That is, the determination unit 23 determines that the cleanliness of water is low when the change rate is smaller than the change threshold.

When the determination unit 23 determines that the cleanliness of water is low, the cleaning control unit 24 causes the cleaning display unit 26 to display a message urging cleaning of at least one of the water storage unit 14 and the filter unit 16. In embodiment 1, a display for prompting cleaning of both the water storage part 14 and the filter part 16 is performed, and a configuration for lighting the LED of the cleaning display part 26 as a display for prompting cleaning will be described. The user can recognize that the water storage part 14 and the filter part 16 need to be cleaned by confirming the display prompting cleaning of the cleaning display part 26.

Further, after a predetermined time has elapsed after the determination unit 23 determines that the cleanliness of water is low, a display urging cleaning by the cleaning display unit 26 is displayed. Here, in embodiment 1, the predetermined time is defined as T1.

If the user performs a display prompting the cleaning display portion 26 to clean the water storage portion 14 and the filter portion 16 after the water supply operation after the water discharge operation, the user may immediately recognize the need to perform the cleaning operation of the water storage portion 14 and the filter portion 16. In this case, the user needs to perform the water discharge operation of water storage unit 14 after performing the water supply operation to water storage unit 14 for the cleaning operation. In this case, the usability of the user is poor.

In order to prevent the user from erroneously recognizing that the cleaning work needs to be performed immediately, the display urging the cleaning display unit 26 to clean is displayed (the display is delayed) after a predetermined time T1 has elapsed after the determination unit 23 determines that the cleanliness of water is low.

Here, the predetermined time T1 is a time required for preventing the user from mistakenly recognizing that the cleaning work needs to be immediately performed, and can be set arbitrarily. The predetermined time T1 is, for example, three hours or more. The determination unit 23 may determine the cleanliness of water after a predetermined time T1 has elapsed after the water discharge operation by the user and the water supply operation after the water discharge operation. In this case, after the water discharge operation and the water supply operation after the water discharge operation performed by the user, the display for urging the cleaning display unit 26 to perform cleaning is not performed. Therefore, it is not necessary to delay the display of urging the cleaning display unit 26 to clean for the predetermined time T1 after the determination unit 23 determines that the cleanliness of water is low.

Here, the cleaning of the water storage part 14 and the filter part 16 by the user means to remove impurities accumulated on the water storage part 14 and the filter part 16. That is, the new resistance value decreases every time the user performs the water supply operation after the water discharge operation, but the new resistance value calculated by index calculation unit 21 increases to a value close to the reference resistance value after the water reservoir unit 14 and the filter unit 16 are cleaned by the user. That is, after the user cleans the water reservoir unit 14 and the filter unit 16, the change rate calculated by the index calculation unit 21 is equal to or greater than the change threshold. Therefore, the determination unit 23 determines that the cleanliness of water is high.

After the cleaning prompting display unit 26 displays the prompting of cleaning, and when the determination unit 23 determines that the cleanliness of water is high, the cleaning control unit 24 determines that the user has performed cleaning, and ends the display prompting the cleaning display unit 26 to perform cleaning. In embodiment 1, a case will be described where the display for prompting cleaning after the end is a display for turning off the LED of the cleaning display unit 26.

Here, the control unit 20 is constituted by a microcomputer. That is, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), and the like are provided in the control Unit 20. The control unit 20 is connected to the electrode unit 17, the water level detection unit 18, the spraying unit 19, the electrolysis accelerator feeding unit 25, and the cleaning display unit 26 via a driver, an internal bus, or the like. The CPU executes a program stored in the ROM using, for example, the RAM as a work area, and receives data, commands, and the like based on the execution result, thereby controlling each operation.

In the above configuration, the determination control of the cleanliness of water by the control unit 20 will be described with reference to the flowchart of fig. 6.

Fig. 6 is a flowchart showing the control of determining the cleanliness of water performed by the control unit 20 according to embodiment 1. Here, in the flowchart, for each processing step, a number is assigned with S as an initial letter. For example, S1 and the like refer to processing steps. However, the magnitude of the numerical value indicating the processing step is not related to the processing order.

First, the index calculation unit 21 calculates (measures) a reference resistance value after water supply, and stores the reference resistance value in the storage unit 22 (S1).

Next, the electrolysis promoter introduction section 25 introduces the electrolysis promoter into the water storage section 14. Thereby, the electrolytic water spray device D is operated (S2).

After that, the user performs a drainage operation (S3). As a method for detecting the water discharge operation by the user, for example, a water discharge button may be provided in the electrolytic water spraying device D, and the user presses the water discharge button after water discharge, and the control unit 20 may detect that the button has been pressed. In addition, as long as it is possible to detect that the user performs drainage, the detection method may be other than this.

If the water supply operation is performed after the water discharge operation, the index calculation section 21 calculates (measures) a new resistance value and a rate of change (S4). At this time, the determination unit 23 determines whether or not the change rate is smaller than the change threshold.

The water supply operation by the user can be detected by, for example, detecting that the water level of water storage unit 14 is equal to or higher than a predetermined water level by water level detection unit 18. In addition, as long as the water supply by the user can be detected, the detection method may be other than this.

Regardless of the result of the determination by the determination unit 23, the electrolysis promoter introduction unit 25 introduces the electrolysis promoter into the water storage unit 14 (S5).

The electrolytic water spraying device D is operated (S6).

The cleaning control unit 24 confirms the determination result after a predetermined time T1 has elapsed from the determination by the determination unit 23 (S7).

When it is confirmed that the change rate is smaller than the change threshold value, the cleaning control unit 24 turns on the LED as the cleaning display unit 26 (yes in S7 → S8). This can notify the user that impurities are accumulated in the water reservoir portion 14, the filter portion 16, or the like, and that the user is in a state requiring cleaning of the water reservoir portion 14 and the filter portion 16.

In step S7, when it is confirmed that the change rate is equal to or greater than the change threshold, the cleaning control unit 24 turns off the LED as the cleaning display unit 26 (no in S7 → S9). This allows the user to recognize that the water storage unit 14 and the filter unit 16 are in a state where cleaning is not yet necessary.

If step S8 or step S9 is performed, the electrolytic water sprinkler D continues to operate (S10).

Then, at a time point when the user needs to perform the drainage work, the user performs the drainage work (S11). The time at which the user is required to perform the drainage work is, for example, the time at which the drainage work is performed after a lapse of time T2 determined in advance by an experiment or the like from the start of the operation. In this case, T2 is a longer time than T1.

After the water supply by the user, the index calculation unit 21 calculates a new resistance value and a new change rate (S4). The determination unit 23 determines whether or not the change rate is smaller than a change threshold.

Thereafter, the processing of step S5 to step S11 is performed. Thereafter, the processing of step S4 to step S11 is similarly repeated. This can urge the user to clean the water storage unit 14 and the filter unit 16 at a proper time. Further, when the cleaning display unit 26 is turned on in step S8 and the cleaning display unit 26 is turned off from the on state in step S9, the user can grasp that cleaning of the water storage unit 14 and the filter unit 16 has been smoothly performed.

(embodiment mode 2)

Embodiment 2 will be described next. Embodiment 2 relates to determination control of water cleanliness as in embodiment 1. In embodiment 1, the reference resistance value and the new resistance value are calculated before the introduction of the electrolytic accelerator. In embodiment 2, the reference resistance value and the new resistance value are calculated after the introduction of the electrolytic accelerator. However, the resistance value does not stably fluctuate from the introduction of the electrolysis accelerator until the electrolysis accelerator is dissolved in the water storage portion 14. Therefore, after a certain time, which is the time until the electrolytic accelerator is dissolved in the water storage portion 14, has elapsed, the index calculation portion 21 calculates the reference resistance value and calculates the new resistance value. The fixed time is a value determined in advance by an experiment or the like, and can be arbitrarily set.

The electrolytic water sprinkler D of embodiment 2 has the same structure as that shown in FIGS. 1 to 5. Here, the following description will focus on differences from embodiment 1, with reference to fig. 7.

Fig. 7 is a flowchart showing the determination control of the cleanliness of water by the control unit 20 according to embodiment 2.

First, after water is supplied to the water storage part 14, the electrolysis promoter introduction part 25 introduces the electrolysis promoter (S12).

After a certain time has elapsed after the introduction of the electrolytic promoter, the index calculation unit 21 calculates (measures) a reference resistance value, and stores the reference resistance value in the storage unit 22 (S13).

Subsequently, the electrolytic water spray device D is operated (S14).

After that, the user performs a drainage operation (S15).

After the water discharge operation, the water supply operation is performed, and after the water supply to the water storage part 14, the electrolysis accelerator introduction part 25 introduces the electrolysis accelerator (S16).

After a certain time has elapsed after the introduction of the electrolytic accelerator, the index calculation unit 21 calculates (measures) a new resistance value and a change rate (S17). At this time, the determination unit 23 determines whether or not the change rate is smaller than the change threshold.

The electrolytic water spraying device D is operated regardless of the determination result of the determination unit 23 (S18).

After the predetermined time T1 has elapsed from the determination by the determination unit 23, the cleaning control unit 24 confirms the determination result (S19).

When it is confirmed that the change rate is smaller than the change threshold value, the cleaning control unit 24 turns on the LED as the cleaning display unit 26 (yes in S19 → S20).

In step S19, when it is confirmed that the change rate is equal to or greater than the change threshold, the cleaning control unit 24 turns off the LED as the cleaning display unit 26 (no in S19 → S21).

Steps S22 and S23 are the same as steps S10 and S11 of embodiment 1, and thus are omitted. Next, the processing of step S16 to step S23 is repeated. Thus, even when the reference resistance value and the new resistance value are calculated after the introduction of the electrolytic promoting agent, the user can be prompted to clean the water storage unit 14 and the filter unit 16 for a certain period of time.

The present invention has been described above based on the embodiments, but the present invention is not limited to the above embodiments, and it can be easily estimated that various modifications can be made without departing from the scope of the present invention.

For example, the resistance value is calculated as an example of the electrolytic efficiency, but a conductivity value which is the reciprocal of the resistance value may be used. This enables control using the conductivity value.

The electrolytic water sprayer D may not have the tank 15a as the water supply unit 15. In this case, the electrolytic water sprinkler D is supplied with water from tap water. When the water level in water storage unit 14 is lowered, tap water may be supplied before the water level in water storage unit 14 is raised to a predetermined position. Thus, the present invention can be realized in a configuration different from that of the present embodiment.

The electrolytic water spraying device D may not have the electrolysis accelerator introduction section 25. In this case, the electrolytic water spraying device D instructs the user to put the electrolysis promoting tablet by a display, a sound, or the like, thereby prompting the user to put the electrolysis promoting tablet directly into the water storage portion 14. This can simplify the structure.

The change rate and the cleanliness of water corresponding to the change rate may be stored as a table. In this case, the calculated change rate and the cleanliness of the water corresponding to the calculated change rate are derived from the table, and when the cleanliness of the water is low, cleaning of at least one of the water storage portion 14 and the filter portion 16 is urged. Thus, the present invention can be realized in a configuration different from that of the present embodiment.

(summary of the invention)

The electrolytic water sprinkler of the present invention comprises: a main body casing provided with an air inlet and an air outlet; a water storage part for storing water; an electrode unit for electrolyzing water in the water storage unit to generate electrolyzed water; a spraying part which makes the generated electrolyzed water contact with the air sucked from the air inlet and sprays from the air outlet; and a control section that controls the electrode section and the spraying section. The control unit includes: an index calculation unit that calculates an index of the electrolysis efficiency with respect to a predetermined reference based on a relationship between the voltage and the current applied to the electrode unit; and a determination unit for determining the cleanliness of the water in the water storage unit based on the index calculated by the index calculation unit.

Thus, the cleanliness of water can be determined by calculating the electrolysis efficiency with respect to a predetermined reference. Therefore, the cleanliness of the water in the water storage portion can be grasped.

The index calculation unit may calculate, after the water is supplied to the water storage unit, a resistance value of the water, which is a ratio of a voltage value of a voltage applied to the electrode portion to a current value of a current flowing through the electrode portion, as a reference resistance value, and may calculate, after the reference resistance value is calculated, a resistance value of the water as a new resistance value and calculate, as the index, a rate of change of the new resistance value with respect to the reference resistance value every time the water in the water storage unit is discharged and new water is supplied to the water storage unit. The determination unit may compare the change rate calculated by the index calculation unit with a change threshold value, and determine that the cleanliness of water is low when the change rate is smaller than the change threshold value, and determine that the cleanliness of water is high when the change rate is equal to or larger than the change threshold value.

This makes it possible to compare the change rate of the new resistance value calculated every time water in the water storage portion is discharged and new water is supplied to the water storage portion with respect to the reference resistance value calculated after water is supplied to the water storage portion, with the change threshold value. Thus, when the change rate is smaller than the change threshold, the cleanliness of water can be determined to be low, and when the change rate is equal to or greater than the change threshold, the cleanliness of water can be determined to be high. Therefore, the cleanliness of the water in the water storage portion can be grasped.

The index calculation unit may calculate, as the reference resistance value, a resistance value of water that is a ratio of a voltage value of a voltage applied to the electrode portion to a current value of a current flowing through the electrode portion after a certain time has elapsed since the water is supplied to the water reservoir and the electrolysis accelerator is introduced into the water reservoir, calculate, as the new resistance value, a resistance value of water every time water in the water reservoir is drained and fresh water is supplied to the water reservoir after the reference resistance value is calculated, and calculate, as the index, a rate of change in the new resistance value from the reference resistance value after a certain time has elapsed since the electrolysis accelerator is introduced into the water reservoir. The determination unit may compare the change rate calculated by the index calculation unit with a change threshold value, and determine that the cleanliness of water is low when the change rate is smaller than the change threshold value, and determine that the cleanliness of water is high when the change rate is equal to or larger than the change threshold value.

Thus, the change rate calculated from the reference resistance value and the new resistance value after the introduction of the electrolytic promoter is compared with the change threshold value, and if the change rate is smaller than the change threshold value, it is determined that the cleanliness of water is low, and if the change rate is equal to or greater than the change threshold value, it is determined that the cleanliness of water is high. Therefore, the cleanliness of the water in the water storage portion can be grasped.

The fixed time may be a time until the electrolytic accelerator is dissolved in the water reservoir.

This stabilizes the resistance value that fluctuates after the introduction of the electrolytic promoter for a certain period of time, and therefore, the accurate reference resistance value and the new resistance value can be calculated. Further, it is possible to prevent the determination unit from making a mistake in determining the cleanliness of water.

The water storage device may further include a filter unit that is immersed in the water storage unit and holds the water in the water storage unit, and a cleaning display unit that displays a prompt to clean at least one of the water storage unit and the filter unit when the determination unit determines that the cleanliness of the water is low.

This can urge the user to clean the water container while dirt is deposited on at least one of the water storage unit and the filter unit.

The display for urging cleaning by the cleaning display unit may be displayed after a predetermined time has elapsed after the determination unit determines that the cleanliness of water is low.

This prevents the user from erroneously recognizing that the water supply operation and the water discharge operation are required for the cleaning operation.

Further, after the display prompting cleaning is performed by the cleaning display unit and the determination unit determines that the cleanliness of water is high, the display prompting cleaning may be ended.

This enables the user to know that the cleaning operation has been performed correctly.

Industrial applicability of the invention
