The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

(Embodiment 1)
(1) Functional Water-Using Device FIG. 1 is a functional block diagram of a functional water-using device 1 according to a first embodiment.

The functional water-using device 1 includes an object to be washed 10 and a functional water supply system 20. The functional water-using device 1 is, for example, a plumbing device such as a flush toilet, a washbasin, a sink, or a bathroom. The functional water-using device 1 is, for example, a home appliance such as a washing machine, a dishwasher, a refrigerator, or a water server. The functional water-using device 1 is, for example, a kitchen appliance such as an ice maker, a drink server, or a soft serve ice cream machine.

The functional water supply system 20 is a system for supplying functional water W2 to the object 10 to be cleaned of the functional water utilization device 1. The object 10 to be cleaned is cleaned with the functional water W2 supplied from the functional water supply system 20. The functional water W2 is, for example, sterilized water (electrolyzed water) made of ozone water, hypochlorous acid water, silver ion water, zinc ion water, or copper ion water.

The object to be cleaned 10 is a part or all of the portion of the functional water-using device 1 through which water flows. For example, if the functional water-using device 1 is a flush toilet, the object to be cleaned 10 is the bowl portion of the toilet body. If the functional water-using device 1 is a sink, the object to be cleaned 10 is the sink portion. If the functional water-using device 1 is a washing machine, the object to be cleaned is the washing tub.

(2) Functional Water Supply System As shown in Fig. 1, the functional water supply system 20 includes a generator (functional water generator) 21, a water discharger 22, a sensor unit 23, a water supply unit 24, and a controller 25. Here, the arrows in Fig. 1 indicate the flow of raw water W1 or functional water W2, and the dashed lines in Fig. 1 indicate electrical connections. That is, in the example of Fig. 1, the controller 25 and the sensor unit 23 are electrically connected. Note that the electrical connection between the controller 25 and the sensor unit 23 may be a wired connection or a wireless connection.

(2.1) Generation unit The generation unit 21 generates functional water W2. More specifically, the generation unit 21 generates functional water W2 using raw water W1 supplied from the water supply unit 24. The functional water W2 is, for example, sterilized water made of ozone water, hypochlorous acid water, silver ion water, zinc ion water, or copper ion water. In the present embodiment, as an example, the functional water W2 is ozone water. Ozone water is functional water that has immediate effect and self-decomposition properties. In the present disclosure, "raw water" includes water before water purification treatment (natural water) and water after water purification treatment (tap water). The raw water W1 is, for example, tap water.

The generator 21 has an electrolytic cell (not shown), an anode (not shown), a cathode (not shown), and a conductive membrane (not shown). The conductive membrane is disposed between the anode and the cathode. The anode, cathode, and conductive membrane are stored in the electrolytic cell. The generator 21 generates ozone by electrolyzing raw water W1 from the water supply unit 24, and generates ozone water (functional water W2) by dissolving the ozone in the raw water W1.

More specifically, when raw water W1 is supplied to the electrolytic cell and a drive voltage is applied between the anode and the cathode, a potential difference is generated between the anode and the cathode via the conductive membrane. The generation of a potential difference between the anode and the cathode causes the anode, conductive membrane, and cathode to be electrified, and a drive current flows from the anode to the cathode. When the drive current flows, the raw water W1 is electrolyzed, and ozone is generated near the interface between the conductive membrane and the anode. The ozone dissolves in the raw water W1 in the electrolytic cell, and ozone water (functional water W2) is produced.

The driving voltage applied between the anode and the cathode is several volts to several tens of volts, and the larger the driving current (the higher the driving voltage), the greater the amount of ozone generated. The generator 21 can adjust the amount of ozone contained in the functional water W2 by adjusting the driving current. More specifically, the generator 21 can increase the amount of ozone contained in the functional water W2 by increasing the driving current to increase the amount of ozone generated, thereby improving the sterilization function of the functional water W2. The generator 21 can also reduce the amount of ozone contained in the functional water W2 by decreasing the driving current to decrease the amount of ozone generated, thereby decreasing the sterilization function of the functional water W2.

The generation unit 21 is not limited to the above configuration and may have other configurations.

(2.2) Water discharge section The water discharge section 22 is provided on the object to be cleaned 10, and discharges the functional water W2 onto the area to be cleaned 11 of the object to be cleaned 10. Details will be described later.

(2.3) Sensor unit The sensor unit 23 measures the state of the object 10 to be cleaned or the state of the surroundings of the object 10 to be cleaned. The control unit 25 identifies the cleaning target area 11 of the object 10 to be cleaned based on the measurement result of the sensor unit 23. More specifically, the sensor unit 23 is a sensor that acquires the state of the object 10 to be cleaned or the state of the surroundings of the object 10 to be cleaned, or a collection of multiple sensors. The cleaning target area 11 refers to an area to be cleaned and disinfected by the functional water W2. The cleaning target area 11 is, for example, an area on the object 10 to be cleaned where dirt such as organic matter, fungi, and bacteria exists, or an area where dirt is likely to exist. The sensor unit 23 measures, for example, the presence range of fine particles on the object 10 to be cleaned as the state of the object 10 to be cleaned. The control unit 25 identifies the presence range of fine particles on the object 10 to be cleaned as the cleaning target area 11. The sensor unit 23 also measures, for example, an odor as the state of the surroundings of the object 10 to be cleaned. The control unit 25 identifies the area 11 to be cleaned based on the odor distribution state.

(2.4) Water Supply Unit The water supply unit 24 supplies raw water W1 to the generation unit 21. For example, as shown in FIG. 3A, the water supply unit 24 includes a raw water acquisition unit 241 and a water intake valve 242. The raw water acquisition unit 241 is, for example, a water supply pipe for connecting to a water pipe. The water intake valve 242 is, for example, a valve that can be opened and closed manually, such as a faucet, a cock valve, or a ball valve. The water intake valve 242 may also be an electromagnetic valve controlled by the control unit 25.

The control unit 25 is mainly composed of a computer system having one or more processors and one or more memories. In the functional water supply system 20, the functions of the control unit 25 are realized by one or more processors executing a program recorded in the memory. The program may be pre-recorded in the memory, may be provided via a telecommunications line such as the Internet, or may be provided recorded on a non-temporary recording medium such as a memory card.

The control unit 25 is electrically connected to each of the generation unit 21 and the water discharge unit 22. The control unit 25 causes the generation unit 21 to generate the functional water W2. More specifically, the control unit 25 changes the generation mode of the generation unit 21 based on the state of the object to be cleaned 10 measured by the sensor unit 23 or the state around the object to be cleaned 10. The generation mode of the generation unit 21 refers to the details of the operation of the generation unit 21, such as the concentration of the functional water W2 of the generation unit 21. The control unit 25 also causes the water discharge unit 22 to discharge the functional water W2. More specifically, the control unit 25 changes the discharge mode of the water discharge unit 22 based on the state of the object to be cleaned 10 measured by the sensor unit 23 or the state around the object to be cleaned 10. The discharge mode of the water discharge unit 22 refers to the details of the operation of the water discharge unit 22, such as the discharge direction and discharge amount of the functional water W2 of the water discharge unit 22.

(3) Detailed Configuration of Water Discharge Unit and Sensor Unit Hereinafter, the detailed configuration of the water discharge unit 22 and the sensor unit 23 will be described.

(3.1) Configuration of Sensor Unit As shown in FIG. 2, the sensor unit 23 is a sensor that measures the state of the object 10 to be cleaned.

The sensor unit 23 includes, for example, a current sensor. The current sensor detects the position of the particles on the object to be cleaned 10. The control unit 25 identifies the range in which the particles exist as the area to be cleaned 11.

The sensor unit 23 also includes, for example, an optical sensor. The optical sensor measures the surface of the cleaning target 10 using visible light or infrared light. The optical sensor measures, for example, the intensity of infrared light emitted from the surface of the cleaning target 10. The control unit 25 specifies the area where the intensity of infrared light is weaker than a reference as the cleaning target area 11. The control unit 25 may specify the area where the intensity of infrared light is stronger than a reference as the cleaning target area 11. For example, the sensor unit 23 may include a light irradiation unit in addition to the optical sensor, and the optical sensor may measure the intensity of reflected light from the cleaning target 10 with respect to the light irradiated by the light irradiation unit. The control unit 25 specifies, for example, the area where the reflected light with respect to the light irradiated by the light irradiation unit is stronger than a reference as the cleaning target area 11. For example, the control unit 25 specifies, for example, the area where the reflected light with respect to the light irradiated by the light irradiation unit is weaker than a reference as the cleaning target area 11.

(3.2) Configuration of the Water Discharger The water discharger 22 discharges functional water W2 onto the area to be cleaned 11 of the object to be cleaned 10, and cleans and sterilizes the area to be cleaned of the object to be cleaned 10 with the functional water W2.

The water discharge unit 22 is configured to change the discharge direction of the functional water W2. More specifically, the water discharge unit 22 includes a nozzle 221 and a nozzle base 222, as shown in FIG. 2, for example. The nozzle base 222 is connected to the generation unit 21 (see FIG. 1), for example. The nozzle 221 is, for example, rod-shaped and has a first end 221a and a second end 221b. The nozzle 221 has a water discharge port 223 at the first end 221a. The water discharge port 223 can discharge the functional water W2 in a direction that depends on the extension direction of the nozzle 221. The water discharge port 223 can discharge the functional water W2, for example, along the extension direction of the nozzle 221. The water discharge port 223 may also be configured to discharge the functional water W2 in a direction that forms a specific angle with respect to the extension direction of the nozzle 221, for example. The second end 221b of the nozzle 221 is held by the nozzle base 222 so that the extension direction of the nozzle 221 can be changed. This makes it possible to change the direction in which the functional water W2 is discharged from the water outlet 223, for example, by changing the extension direction of the nozzle 221.

For example, the second end 221b of the nozzle 221 is a ball joint. This allows the water outlet 223 of the nozzle 221 to move in multiple directions perpendicular to the extension direction of the nozzle 221. That is, the first end 221a of the nozzle 221 can move inside the bottom surface 221d of the cone-shaped region 221c whose apex is the second end 221b of the nozzle 221. This expands the range of the object 10 that can be cleaned with the functional water W2 from the water outlet 223 of the nozzle 221, making it possible to clean a desired position of the object 10 with one nozzle 221.

The water discharger 22 further includes a drive device (not shown) for the nozzle 221. The drive device is controlled by the control unit 25. The control unit 25 controls the drive device to control the direction in which the water discharger 22 discharges the functional water W2.

The water discharge section 22 may be any device that has a water discharge port that discharges the functional water W2 onto the area 11 to be cleaned of the object 10 to be cleaned, and may include, for example, a configuration in which a water discharge port is provided on the outer surface of the main body of the functional water-using device 1, a pipe, etc.

(4) Operation Hereinafter, the operation of the functional water utilization device 1 will be described.

The control unit 25 of the functional water utilization device 1 identifies the area 11 to be cleaned based on the measurement results of the sensor unit 23. The control unit 25 identifies the area 11 to be cleaned based on the measurement results of, for example, fine particles on the object 10 to be cleaned or a light absorption source. If the control unit 25 is unable to identify the area to be cleaned 11, it acquires the measurement results from the sensor unit 23 after a certain period of time, for example, and identifies the area to be cleaned 11.

When the control unit 25 identifies the area 11 to be cleaned, the water discharge unit 22 discharges the functional water W2 onto the area 11 to be cleaned. More specifically, based on instructions from the control unit 25, the nozzle 221 of the water discharge unit 22 controls the position of the water outlet 223. The water discharge unit 22 discharges a predetermined amount of functional water W2 from the water outlet 223 of the nozzle 221. As a result, the area 11 to be cleaned of the object 10 to be cleaned is cleaned and disinfected by the functional water W2.

After the water discharger 22 discharges the functional water W2, the control unit 25 acquires the measurement results from the sensor unit 23 and identifies the area to be cleaned 11. If the area to be cleaned 11 has been sufficiently cleaned and disinfected by the functional water W2, the control unit 25 does not identify the area to be cleaned 11. On the other hand, if dirt remains in the area to be cleaned 11, the control unit 25 identifies the part where dirt remains as the area to be cleaned 11 based on the measurement results from the sensor unit 23. In this case, the water discharger 22 discharges the functional water W2 onto the area to be cleaned 11.

By the above operation, in the functional water-using device 1 of embodiment 1, the area 11 to be cleaned is cleaned and sterilized with the functional water W2. As a result, in the functional water-using device 1 of embodiment 1, cleaning and sterilization with the functional water W2 is not necessarily performed on the entire area of the object 10 to be cleaned. Therefore, it is possible to reduce the amount of functional water W2 used and efficiently clean and sterilize the object 10 to be cleaned.

In addition, in the functional water-using device 1 of embodiment 1, the water discharge section 22 is configured so that the discharge direction of the functional water W2 can be changed. More specifically, in the functional water-using device 1 of embodiment 1, the water discharge section 22 has a nozzle 221, and the water discharge port 223 of the nozzle 221 is configured so that it can be moved in any direction perpendicular to the extension direction of the nozzle 221. This makes it possible to apply the functional water W2 to an area of the object to be cleaned 10 that includes the area to be cleaned 11. Therefore, no matter where and in what area of the object to be cleaned 10 the area to be cleaned 11 is located, the area to be cleaned 11 can be cleaned.

(Variation 1)
In the functional water-utilizing device 1 according to the first modified example of the first embodiment, the water supply section 24 of the functional water supply system 20 has the following configuration.

In the functional water-using device 1 according to the first modified example of the first embodiment, the water supply unit 24 further includes a water storage tank 243 and a water outlet valve 244, for example, as shown in FIG. 3B. The water outlet valve 244 is a valve that can be opened and closed manually, such as a faucet, a cock valve, or a ball valve. The water outlet valve 244 may also be, for example, an electromagnetic valve controlled by the control unit 25.

Even with this configuration, the water supply section 24 of the functional water supply system 20 can supply raw water W1 to the generation section 21.

In the functional water utilization device 1 according to the first modified example of the first embodiment, the water supply unit 24 may be configured not to include, for example, the raw water acquisition unit 241 and the water intake valve 242. In this case, the water storage tank 243 has, for example, a water supply port for refilling the raw water W1. Even with this configuration, the water supply unit 24 of the functional water supply system 20 can supply the raw water W1 to the generation unit 21.

(Variation 2)
In the functional water-utilizing device 1 according to the second modification of the first embodiment, the water supply section 24 of the functional water supply system 20 has the following configuration.

In the functional water-using device 1 according to the second modification of the first embodiment, the water supply unit 24 includes, for example, a raw water acquisition unit 241, a water intake valve 242, a water storage tank 243, and a water outlet valve 244, as well as a water supply pump 245, as shown in FIG. 3C. The water supply pump 245 is a pump that pressurizes and supplies water from the water storage tank 243 that is released from the water outlet valve 244 to the generation unit 21. With this configuration, the water pressure of the raw water W1 at the water outlet valve 244 may be lower than the water pressure required to supply the raw water W1 from the water outlet valve 244 to the generation unit 21. Therefore, for example, it is possible to place the water storage tank 243 at a lower position than the generation unit 21.

In the functional water utilization device 1 according to the second modification of the first embodiment, the water supply unit 24 may be configured not to include, for example, the raw water acquisition unit 241 and the water intake valve 242. In this case, the water storage tank 243 has, for example, a water supply port for refilling the raw water W1. Even with this configuration, the water supply unit 24 of the functional water supply system 20 can supply the raw water W1 to the generation unit 21.

(Embodiment 2)
In the functional water utilization device 1 according to the second embodiment, the water discharger 22 has a water discharge port 223a that discharges the functional water W2 radially.

The water outlet 223a is, for example, a circular water outlet as shown in Figures 4A and 4B. In the water outlet 22, the flow path 224 of the nozzle 221 spreads out radially and opens into the water outlet 223a. More specifically, the nozzle 221 has a cone-shaped flow path 224 as shown in Figure 4C, for example. Therefore, the functional water W2 is discharged radially from the water outlet 223a of the nozzle 221.

According to the functional water-using device 1 of the second embodiment, the functional water W2 is radially discharged from the water outlet 223a of the water outlet 22. Therefore, the functional water W2 can be discharged from one water outlet 223a over a wide area of the object to be cleaned 10. In addition, it is possible to discharge the functional water W2 over a wide area of the object to be cleaned 10 without changing the discharge direction of the functional water W2 from the water outlet 223a. Therefore, it is easy for the water outlet 22 to discharge the functional water W2 onto the area to be cleaned 11 regardless of the position of the area to be cleaned 11 on the object to be cleaned 10. In addition, even if the area to be cleaned 11 of the object to be cleaned 10 is wide, the object to be cleaned 10 can be efficiently cleaned and disinfected with the functional water W2.

(Embodiment 3)
In the functional water-using device 1 according to the third embodiment, the water discharge section 22 (see FIG. 1) includes a plurality of water discharge ports 223 (see FIG. 2).

More specifically, in the functional water-utilizing device 1 according to embodiment 3, the water discharge section 22 has a plurality of nozzles. Of the plurality of nozzles, one is nozzle 221 (see FIG. 2). Nozzle 221 has a water discharge port 223. Of the plurality of nozzles, the nozzles other than nozzle 221 have the same configuration as nozzle 221. Note that, of the plurality of nozzles, the nozzles other than nozzle 221 may have the same discharge port as water discharge port 223a (see FIG. 4A to FIG. 4C).

The multiple nozzles have different ranges of the object to be cleaned 10 into which the functional water W2 can be discharged. More specifically, the range of the object to be cleaned 10 into which the nozzle 221 can discharge the functional water W2 includes the outside of the range of the object to be cleaned 10 into which the nozzles other than the nozzle 221 can discharge the functional water W2. Similarly, the range of the object to be cleaned 10 into which the nozzles other than the nozzle 221 can discharge the functional water W2 includes the outside of the range of the object to be cleaned 10 into which the nozzle 221 can discharge the functional water W2. Preferably, any position of the object to be cleaned 10 is included in the range into which the functional water W2 can be discharged from at least one of the multiple nozzles included in the water discharge section 22. This makes it possible to clean and disinfect with the functional water W2 regardless of the position of the object to be cleaned 10 into which the area to be cleaned 11 is located.

According to the functional water-using device 1 of embodiment 3, the water discharge section 22 has multiple water discharge ports. This makes it easy for the water discharge section 22 to discharge the functional water W2 onto the area 11 to be cleaned.

In addition, in the functional water-using device 1 according to the third embodiment, at least one of the nozzles other than the nozzle 221 included in the water discharge section 22 may be capable of discharging the functional water W2 to the nozzle 221 included in the water discharge section 22. This makes it possible to clean and disinfect the nozzle 221 and the vicinity of the nozzle 221 with the functional water W2.

(Embodiment 4)
The functional water-using device 1 according to the fourth embodiment is a toilet bowl and has the following configuration.

As shown in FIG. 5, the functional water-using device 1 includes a toilet body 31, a toilet seat 32, and a toilet cover 33. The functional water-using device 1 is a so-called Western-style toilet that is used while the user is seated. The toilet body 31 includes a bowl portion 10 that opens upward. In the functional water-using device 1 according to the fourth embodiment, the bowl portion 10 corresponds to the object to be cleaned 10. In other words, the toilet body 31 includes the object to be cleaned 10. The toilet seat 32 and the toilet cover 33 are rotatably arranged above the toilet body 31. More specifically, the toilet seat 32 is arranged above the bowl portion 10. The toilet cover 33 is arranged above the bowl portion 10 and is configured to cover the upper part of the bowl portion 10 and the toilet seat 32.

The functional water-using device 1 is equipped with a seating sensor 34. The seating sensor 34 detects whether or not a user is sitting on the toilet seat 32.

In the functional water-using device 1 according to the fourth embodiment, the sensor unit 23 is a sensor that measures the surrounding condition of the object 10 to be cleaned. More specifically, the sensor unit 23 includes an odor sensor 231 that measures the odor of the object 10 to be cleaned. The odor sensor 231 detects odorous substances that are diffused from dirt on the object 10 to be cleaned. Examples of odorous substances are ammonia, trimethylamine, and phenolic compounds. The control unit 25 identifies, for example, an area with a high concentration of odorous substances as the area 11 to be cleaned. This eliminates the need for the sensor unit 23 to directly detect dirt on the bowl portion 10 of the toilet body 31, and there is no risk of the sensor unit 23 becoming dirty with the cleaning water from the bowl portion 10.

The sensor unit 23 may have, for example, a current sensor or an optical sensor in addition to the odor sensor 231 or instead of the odor sensor 231.

In the functional water-using device 1 according to the fourth embodiment, when the seat sensor 34 does not detect a user, the control unit 25 identifies the area to be cleaned 11 based on the measurement results of the odor sensor of the sensor unit 23. When the control unit 25 identifies the area to be cleaned 11, the water discharge unit 22 discharges a certain amount of functional water W2 onto the area to be cleaned 11. When the water discharge unit 22 stops discharging the functional water W2, the control unit 25 acquires the measurement results from the sensor unit 23 and identifies the area to be cleaned 11. Here, for example, when the control unit 25 identifies the area to be cleaned 11, the water discharge unit 22 discharges the functional water W2 onto the area to be cleaned 11. On the other hand, when the control unit 25 does not identify the area to be cleaned 11, for example, the control unit 25 identifies the area to be cleaned 11 using the measurement results of the odor sensor of the sensor unit 23, triggered by a specific event. The specific event is, for example, an event in which the seat sensor 34 does not detect a user for a certain period of time, or an event in which the user disappears after the seat sensor 34 detects the user. In particular, when the seating sensor 34 does not detect the user for a certain period of time, the control unit 25 identifies the area 11 to be cleaned, which can prevent, for example, the spread of dirt in the bowl portion 10 due to the proliferation of microorganisms. That is, in the functional water-using device 1 according to the fourth embodiment, even if there is a continuous period of time in which water does not flow through the bowl portion 10, the bowl portion 10 can be periodically cleaned and disinfected with the functional water W2.

In addition, in the functional water-using device 1 according to the fourth embodiment, the water discharger 22 does not discharge the functional water W2 while the seating sensor 34 detects the user. This prevents water containing the functional water W2 from splashing on the user who is using the functional water-using device 1, thereby preventing discomfort to the user of the functional water-using device 1.

In the functional water-using device 1 according to the fourth embodiment, when the seating sensor 34 does not detect a person, the control unit 25 identifies the area 11 to be cleaned based on the measurement results of the sensor unit 23, and the water discharge unit 22 discharges the functional water W2 into the area 11 to be cleaned in the bowl unit 10. Therefore, the bowl unit 10 can be cleaned while the functional water-using device 1 is not in use, so that the functional water W2 can be prevented from causing discomfort to the user of the functional water-using device 1.

(Embodiment 5)
The functional water-using device 1 according to the fifth embodiment is a toilet bowl and has the following configuration.

As shown in FIG. 6, the functional water-using device 1 includes a toilet body 31, a toilet seat 32, a toilet lid 33, and a seating sensor 34. The toilet body 31, the toilet seat 32, the toilet lid 33, and the seating sensor 34 are similar to the toilet body 31, the toilet seat 32, the toilet lid 33, and the seating sensor 34 of the functional water-using device 1 according to embodiment 4, and therefore description thereof will be omitted.

The sensor unit 23 includes a human presence sensor 232 in addition to an odor sensor 231. The human presence sensor 232 detects whether or not a person P1 is present around the toilet body 31 when the toilet lid 33 is open. The surroundings of the toilet body 31 here refers to the range in which the toilet body 31 is visible, and includes, for example, the inside of the toilet stall in which the toilet body 31 is installed and the hallway in front of the stall.

The control unit 25 can also detect whether the toilet lid 33 is closed or open. For example, the control unit 25 is connected to a sensor that can detect the open or closed state of the toilet lid 33. For example, the human presence sensor 232 can also detect whether the toilet lid 33 is closed or open.

In the functional water-using device 1 according to the fifth embodiment, when the seating sensor 34 does not detect a user, the control unit 25 identifies the area to be cleaned 11 based on the measurement results of the odor sensor of the sensor unit 23. When the control unit 25 identifies the area to be cleaned 11, the water discharge unit 22 discharges the functional water W2 into the area to be cleaned 11. At this time, the control unit 25 detects the state of the toilet lid 33, and obtains a measurement result from the human presence sensor 232 of the sensor unit 23 as to whether or not a person P1 is present around the toilet body 31. The control unit 25 changes the discharge mode of the water discharge unit 22 based on the state of the toilet lid 33 and the measurement result as to whether or not a person P1 is present around the toilet body 31. Here, the discharge mode refers to the amount of functional water W2 discharged by the water discharge unit 22.

When the toilet lid 33 is closed, the control unit 25 does not limit the amount of functional water W2 discharged from the water discharge unit 22. The water discharge unit 22 discharges only the first discharge amount of functional water W2 onto the area to be cleaned 11. Also, when the toilet lid 33 is open and the human presence sensor 232 does not detect a person P1, the control unit 25 does not limit the amount of functional water W2 discharged from the water discharge unit 22. The water discharge unit 22 discharges only the first discharge amount of functional water W2 onto the area to be cleaned 11.

On the other hand, when the toilet lid 33 is open and the human presence sensor 232 detects a person P1, the control unit 25 limits the amount of functional water W2 discharged from the water discharge unit 22. The water discharge unit 22 discharges the functional water W2 to the area to be cleaned 11 only at a second discharge amount that is less than the first discharge amount. Therefore, when a person P1 is around the functional water-using device 1, the amount of splashes containing the functional water W2 that are scattered from the bowl portion 10 can be reduced. This makes it possible to reduce the discomfort felt by the person P1.

In the functional water-using device 1 of embodiment 5, when the toilet lid 33 is open and a person P1 is present around the toilet body 31, the amount of functional water W2 discharged from the water outlet 22 is limited. This reduces the amount of splashes containing the functional water W2 that are scattered from the bowl portion 10 when a person P1 is present around the functional water-using device 1, making it possible to reduce the discomfort felt by the person P1.

(Variation 1)
In the functional water utilization device 1 according to the first modified example of the fifth embodiment, when the toilet cover 33 is open and a person P1 is present around the toilet body 31, the ozone concentration of the functional water W2 to be discharged is increased.

In the functional water-using device 1 according to the first modified example of the fifth embodiment, when the seating sensor 34 does not detect a user and the control unit 25 identifies the area 11 to be cleaned based on the measurement results of the sensor unit 23, the water discharge unit 22 discharges the functional water W2 into the area 11 to be cleaned in the bowl unit 10.

At this time, if the toilet lid 33 is closed, the control unit 25 does not limit the amount of functional water W2 discharged from the water discharge unit 22. The water discharge unit 22 discharges only the first discharge amount of functional water W2 onto the area to be cleaned 11. Also, if the toilet lid 33 is open and the human presence sensor 232 does not detect a person P1, the control unit 25 does not limit the amount of functional water W2 discharged from the water discharge unit 22. The water discharge unit 22 discharges only the first discharge amount of functional water W2 onto the area to be cleaned 11.

In contrast, when the toilet lid 33 is open and the human sensor 232 detects a person P1, the control unit 25 limits the amount of functional water W2 discharged from the water discharge unit 22. The water discharge unit 22 discharges the functional water W2 to the area to be cleaned 11 by a second discharge amount that is less than the first discharge amount. At this time, the control unit 25 causes the generation unit 21 to increase the ozone concentration of the functional water W2. More specifically, the ozone concentration of the functional water W2 is increased by increasing the driving current between the anode and the cathode in the electrolytic cell of the generation unit 21. As a result, when the toilet lid 33 is open and the human sensor 232 detects a person P1, the amount of splashes containing the functional water W2 can be reduced by limiting the amount of functional water W2 discharged to the area to be cleaned 11. On the other hand, in this case, the ozone concentration of the functional water W2 is increased and the sterilization ability is improved, so even if the amount of functional water W2 discharged to the area to be cleaned 11 is reduced, the degree of decrease in the cleaning and sterilization effect of the area to be cleaned 11 can be reduced. Therefore, with the functional water-using device 1 according to the first modified example of the fifth embodiment, even if the toilet cover 33 is open and there is a person around the toilet body 31, the area to be cleaned 11 can be sufficiently cleaned and sterilized.

(Variation 2)
In the functional water utilization device 1 relating to variant example 2 of embodiment 5, when the toilet lid 33 is open and a person P1 is present around the toilet body 31, the water discharge mode of the water discharge section 22 is changed depending on the distance between the toilet body 31 and the person P1.

In the functional water-using device 1 according to the second modification of the fifth embodiment, the human presence sensor 232 is configured to be able to measure the distance d1 between the toilet body 31 and the person P1.

In the functional water-using device 1 according to variant 2 of embodiment 5, when the seating sensor 34 does not detect a user and the control unit 25 identifies the area 11 to be cleaned based on the measurement results of the sensor unit 23, the water discharge unit 22 discharges the functional water W2 onto the area 11 to be cleaned.

At this time, if the toilet lid 33 is closed, the water discharger 22 discharges the functional water W2 to the area to be cleaned 11 in the first discharge amount. Also, if the toilet lid 33 is open and the human presence sensor 232 does not detect a person P1, the water discharger 22 discharges the functional water W2 to the area to be cleaned 11 in the first discharge amount.

On the other hand, when the toilet cover 33 is open and the human sensor 232 detects a person P1, the control unit 25 changes the water discharge mode of the water discharge unit 22 based on the distance d1 between the toilet body 31 and the person P1 obtained from the human sensor 232. When the distance d1 between the toilet body 31 and the person P1 is less than the reference distance, the control unit 25 limits the discharge amount of the functional water W2 from the water discharge unit 22. The water discharge unit 22 discharges the functional water W2 to the cleaning target area 11 by a second discharge amount that is less than the first discharge amount. At this time, the control unit 25 may cause the generation unit 21 to increase the ozone concentration of the functional water W2. The reference distance refers to the maximum distance between the toilet body 31 and the person P1 when the person P1 may feel discomfort due to splashes containing the functional water W2 when the toilet cover 33 is open. The reference distance is, for example, the distance between the toilet body 31 and the door of the private room in which the toilet body 31 is installed. This makes it possible to reduce the amount of splashes containing functional water W2 that are scattered from the bowl portion 10 when a person P1 is near the functional water-using device 1, thereby reducing the discomfort felt by the person P1.

On the other hand, when the distance d1 between the toilet body 31 and the person P1 is equal to or greater than the reference distance, the control unit 25 does not limit the amount of functional water W2 discharged from the water discharge unit 22. The water discharge unit 22 discharges only the first amount of functional water W2 onto the area to be cleaned 11.

In other words, in the functional water-using device 1 according to the second modification of the fifth embodiment, when the distance d1 between the toilet body 31 and the person P1 is equal to or greater than the reference distance, the amount of functional water W2 discharged from the water discharge section 22 is not restricted. As a result, when the possibility that droplets containing the functional water W2 will reach the person P1 is sufficiently low, the functional water-using device 1 discharges a sufficient amount of functional water W2 onto the area to be cleaned 11 of the bowl section 10, making it possible to sufficiently clean and disinfect the area to be cleaned 11.

(Variation 3)
The functional water-using device 1 according to the third modified example of the fifth embodiment is configured so that the toilet cover 33 can be opened and closed by the control unit.

The functional water-using device 1 according to the third modification of the fifth embodiment further includes a drive device (not shown) for opening and closing the toilet lid 33. The drive device is controlled by the control unit 25. In other words, the toilet lid 33 is configured to be able to be opened and closed by the control unit 25.

In the functional water-using device 1 according to the third variant of the fifth embodiment, when the seating sensor 34 does not detect a user and the control unit 25 identifies the area 11 to be cleaned based on the measurement results of the sensor unit 23, the water discharge unit 22 discharges the functional water W2 onto the area 11 to be cleaned.

At this time, if the toilet lid 33 is closed, the water discharger 22 discharges the functional water W2 to the area to be cleaned 11 by the first discharge amount. Also, if the toilet lid 33 is open and the human presence sensor 232 does not detect a person P1, the water discharger 22 discharges the functional water W2 to the area to be cleaned 11 by the first discharge amount.

In contrast, when the toilet lid 33 is open and the human presence sensor 232 detects a person P1, the control unit 25 closes the toilet lid 33. After the control unit 25 closes the toilet lid 33, the water discharge unit 22 discharges the functional water W2 to the cleaning target area 11 by the first discharge amount. That is, in the functional water utilization device 1 according to variant 2 of embodiment 5, when a person P1 is detected around the toilet body 31, the toilet lid 33 is closed to prevent splashing of water containing the functional water W2. This makes it possible to prevent the discomfort caused to the person P1 by splashes containing the functional water W2.

In addition, in the functional water-using device 1 according to variant example 3 of embodiment 5, even when the control unit 25 closes the toilet lid 33, the water discharge unit 22 may discharge the functional water W2 to the area to be cleaned 11 in a second discharge amount that is smaller than the first discharge amount.

In addition, in the functional water-using device 1 according to the third modification of the fifth embodiment, the human presence sensor 232 may be configured to be able to measure the distance d1 between the toilet body 31 and the person P1. In this case, the control unit 25 may close the toilet lid 33 if it is still open when the distance d1 between the toilet body 31 and the person moves away from 0 to a certain distance after the seating sensor 34 changes from a state in which a person is detected to a state in which a person is not detected. The certain distance is, for example, a distance at which it can be estimated that the person will not sit on the toilet seat 32 again, for example, 1 m. This makes it easier to discharge the functional water W2 into the cleaning target area 11 of the bowl portion 10 by quickly closing the toilet lid 33 when the user leaves the toilet body 31 with the toilet lid 33 open.
