Description

Disinfecting water generating device and toilet device provided with the same

The present invention relates to a sterilized water generating device and a toilet device including the same.

The conventional flush toilet device is configured by connecting a flush water tank to the toilet bowl. For the purpose of sterilization, deodorization and the like, a technique of adding a sterilizing agent or generated sterilized water to the wash water stored in a wash water tank and supplied to a toilet bowl is known. Among them, the method of modifying the tap water used as the washing water to make the sterilized water is effective as a means for sterilizing and deodorizing the toilet bowl because it does not require periodic chemical supplementation.

Methods for modifying the tap water to produce sanitized water having a sanitizing action include electrolyzing the tap water to produce sanitizing components such as hypochlorous acid, and removing generated ozone and the like. A method for dissolving a fungal component in washing water is known. As a method of supplying the sterilized water generated in this way to the wash water tank, a method of directly supplying the sterilized water generated in the wash water supply path to the tank is conceivable.

However, the method of directly supplying the sterilized water to the tank requires a large amount of highly concentrated sterilized water in order to obtain a sufficient sterilizing effect. Therefore, in order to obtain such sterilized water, a very large electrode is required, which causes problems of installation space and installation cost of the apparatus.

In order to cope with this problem, a method of generating sterilized water having a high concentration by circulating the sterilized water generated by electrolysis together with the water in the tank using a pump and performing electrolysis a plurality of times is conceivable. However, since a separate pump and a pump drive device are required, there are problems in that the installation space and cost of the device and noise are generated when the pump is driven.
In order to cope with such a problem, a method of providing an electrode in the washing water tank and performing electrolysis in the washing water tank is conceivable (for example, see Patent Document 1).

Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The present invention is not limited to the following embodiment.

<Toilet bowl device>
The toilet device according to the present embodiment can disperse sterilized water uniformly in the wash water tank without using a drive source, and can efficiently supply high-concentration sterilized water. And the cost for installing the drive source is not required. In the sterilized water generating apparatus, the electrode is not exposed to the outside, and safety during maintenance and repair is high. Therefore, the toilet device according to the present embodiment is preferably used particularly as a general household toilet device.

FIG. 1 is a diagram schematically showing the structure of a toilet device according to this embodiment. As shown in FIG. 1, a toilet device 100 according to the present embodiment includes a toilet 1 and a functional unit 2.

The toilet 1 is formed by opening a substantially circular shape vertically downward at a toilet bowl 10, a toilet bowl (not shown) arranged from the center inside the toilet bowl 10 to the front side, and the bottom of the toilet bowl. And a discharge port (not shown).

The functional unit 2 includes a flush water tank 20, a sterilized water generation device 30, and a toilet seat and a toilet lid (not shown) attached to the toilet body 10 so as to be openable and closable.

The washing water tank 20 is disposed at the upper rear part of the toilet body 10 and stores washing water for washing the toilet body 10. The washing water tank 20 includes a tank main body 21 having an open upper surface, a tank cover 22 that covers the side surface of the tank main body 21, and a lid (not shown) that is disposed on the upper surface of the tank main body 21 and covers the upper surface of the tank main body 21. And).

A water supply unit (not shown) and a sterilized water generator 30 are connected to the tank body 21. The cleaning water supplied from the water supply unit is supplied to the tank main body 21, and then is reformed into sterilized water having a sterilizing effect by the sterilizing water generating device 30, and is uniformly dispersed in the tank main body 21. A drain port (not shown) that is opened and closed by a float valve or the like is formed in the lower part of the tank body 21, and the sterilized water stored in the tank body 21 flows out from the drain port in the direction of the arrow. The toilet 1 is supplied and the toilet 1 is washed.

<Sterilized water generator>
FIG. 3 is a schematic diagram showing the sterilized water generator 30 in the present embodiment. As shown in FIG. 3, the sterilized water generating apparatus 30 communicates an electrolysis unit 31, a power source 32, an electrolytic cell 33, and a water storage unit or outside air provided separately from the electrolytic cell 33 and the electrolytic cell 33. And communication ports 341 and 342. The sterilized water generator 30 generates sterilized water by modifying water such as tap water by electrolysis.

The electrolytic cell 33 is composed of an electrically insulating member, and accommodates a plurality of electrodes 311 and 312 composed of an anode and a cathode and water 23. In the electrolytic cell 33, water 23 exists between the electrodes 311 and 312, and this region is a region where the electrolysis unit 31 performs electrolysis. The electrolysis unit 31 electrolyzes the water 23 by applying a voltage to the electrodes 311 and 312 to generate a sterilization component. When the water 23 is tap water, since the tap water normally contains Cl ions, the electrolysis unit 31 generates a disinfecting component by, for example, the following electrolysis reaction.

Anode: 2Cl ⁻ → Cl ₂ + 2e ⁻ (1)
Cl ₂ + H ₂ O → HCl + HClO Formula (2)
Cathode: 2H ₂ O + 2e ⁻ → H ₂ + 2OH ⁻ Formula (3)

Here, HClO (hypochlorous acid) in the formula (2) functions as a sterilizing component having a strong oxidizing power.
By including HClO in the water 23, the toilet device 100 including the sterilized water generating device 30 has a preferable sterilizing effect. That is, for example, the toilet 1 which is a target to be sterilized is preferably sterilized because it is washed with the water 23 containing HClO after the toilet device 100 is used. Further, the tank body 21 and the drainage path for storing the water 23 are preferably sterilized as well.

In FIG. 3, the electrodes 311 and 312 have a pair of an anode and a cathode. However, a plurality of these anodes and cathodes may exist.
The materials used for the anode and cathode in the electrodes 311 and 312 are not particularly limited as long as they can perform the above electrolysis reaction, but a general platinum-coated titanium electrode or the like is preferably used. As another configuration, the anode can be a silver-containing electrode. With this configuration, silver ions are generated from the anode by an electrolysis reaction. Since silver ions function as a sterilizing component having oxidizing power like HClO, the toilet device 100 including the sterilized water generating device 30 and the toilet device 100 have a preferable sterilizing effect even with such a configuration. When the water 23 is well water or the like not containing Cl, the electrolysis reaction that generates HClO does not occur. Therefore, with this configuration, silver ions are generated instead of HClO as a disinfecting component, thereby generating disinfected water. A preferable sterilization effect can be imparted to the toilet device 100 including the device 30.
The sterilizing component is not limited to HClO and silver ions, and any component having a sterilizing effect that can be generated by electrolysis of water, such as active oxygen species such as hydrogen peroxide, may be used.

The power source 32 is connected to the electrodes 311 and 312 and applies a voltage to both electrodes. The power source 32 has an on / off switchable structure, and is preferably on / off controlled by a timer or a concentration detection device (not shown) in order to save power and obtain sterilized water having a desired concentration. That is, in the toilet device 100 including the sterilized water generating device 30, in order to obtain a preferable sterilizing effect, for example, high concentration sterilized water prepared at least once per day for 2 to 3 hours is supplied to the toilet. If it can be flowed, a sufficient effect can be obtained, and it is not always necessary to flow sterilized water having a sufficient sterilizing effect for each washing. Therefore, since the high-concentration sterilized water can be generated once a day by operating the power source 32 only at night, for example, by using the timer, the generated sterilized water is used to perform cleaning once or more a day. Sufficient sterilization effect is obtained. By performing such control, power saving can be achieved and a sufficient sterilization effect can be obtained.

Further, in the power supply 32, the concentration detection device detects the concentration of the sterilizing component contained in the water 23, and performs control such as stopping the generation when the concentration of the sterilizing component exceeds a certain level. The concentration of the sterilizing component can be adjusted to a desired concentration. Similarly, the concentration of the sterilizing component can also be adjusted by adjusting the time for electrolysis with a timer device. For example, for toilet cleaning, HClO is preferably at a concentration of about 1 to 10 ppm, and sterilized water having a preferable concentration can be obtained by performing the above control with a timer or a concentration detector. Moreover, by such control, the disinfected water production | generation apparatus 30 can be used not only for toilet bowl washing | cleaning use but for various uses.
The power supply method of the power supply 32 is not particularly limited and may be a battery or the like. However, it is preferable that the power supply is supplied from the power system in order to save time for battery replacement.

The electrolytic cell 33 is made of an electrically insulating member that does not conduct electricity, and accommodates the electrodes 311 and 312 and the water 23 therein. That is, the electrolytic cell 33 prevents the electrodes 311 and 312 from being exposed to the outside. With such a configuration, when performing maintenance or repair of the toilet device 100 including the sterilized water generating device 30, even if a person puts a hand in the tank body 21, it is possible to prevent the hand from touching the electrode, so There is little risk of. Therefore, safety when performing maintenance or repair of the toilet device 100 is ensured.
The material of the electrolytic cell 33 is not particularly limited as long as it has insulating properties and water resistance, but general-purpose plastics are preferably used from the viewpoint of cost.

The communication ports 341 and 342 are provided in the electrolytic bath 33 and communicate the electrolytic bath 33 with a water storage unit, for example, the tank body 21 in the toilet device 100. In FIG. 3, in the sterilized water generating apparatus 30, there are two communication ports, the first communication port 341 and the second communication port 342, and it is preferable that there are a plurality of communication ports.
The second communication port 342 communicates the electrolytic bath 33 with the outside that is either the water storage unit 20 or the outside air, and communicates the electrolytic bath 33 with the water storage unit 20. It is more preferable.

In the toilet device 100 including the sterilized water generating device 30, the communication ports 341 and 342 communicate the electrolytic cell 33 and the tank body 21, and the first communication port 341 is below the water surface in the tank body 21. That is, it is provided at a low position in the height direction. Here, the “water surface” refers to the water surface in a state where the sterilized water is stored in the tank body 21, and after the sterilized water is supplied from the tank body 21 until the water 23 is supplied. It does not indicate the temporarily lowered water surface.
When the sterilized water generating device 30 is installed outside the tank main body 21, a communication path connecting the communication port and the tank main body 21 may be provided. In such a case, the upper surface of the communication path is tanked from the electrolytic cell 33. It is preferable to incline upward toward the main body 21.

Gases such as hydrogen and oxygen generated by electrolysis in the electrolysis section 31 are directly discharged into the tank main body 21 or the outside air through the communication port 341 or 342, and at this time, water 23 from the tank main body 21 is instead connected to the communication port 341. Alternatively, it flows into the electrolysis unit 31 through 342. Accordingly, water 23 is always supplied from the tank body 21 to the electrolysis unit 31, and at least a part of the electrodes 311 and 312 is always in contact with the water 23. Therefore, the electrodes 311 and 312 are occupied by gas such as hydrogen and oxygen generated by electrolysis, and electrolysis cannot be continued in the electrolysis unit 31.
Here, “always in contact” is sufficient if the tank body 21 is always in contact with the sterilized water, and the sterilized water is supplied from the tank body 21 and then the water 23 is supplied. In the meantime, there is no problem that water is temporarily lost from the electrolysis part 31.

In the toilet apparatus 100 including the sterilized water generating apparatus 30, a process in which gas such as hydrogen and oxygen generated in the electrolysis unit 31 is discharged into the tank body 21 as bubbles is as follows, for example. First, the gas generated in the electrolysis part 31 becomes small bubbles and adheres to the electrodes. When the number of bubbles adhering to the electrode increases, adjacent bubbles are combined to form a large bubble. Since large bubbles are greatly affected by buoyancy, they are detached from the electrodes and discharged as they are from the upper end portion 341a or 342a of the communication port 341 or 342 into the tank body 21, or the upper surface portion 311a of the electrolysis portion 31 (see FIG. 4). When the number of bubbles staying in the upper surface portion 311a increases, a part of the bubbles is pushed out from the upper end portion 341a or 342a of the communication port 341 or 342 to the outside of the electrolysis unit 31. The gas such as hydrogen generated in the electrolysis unit 31 in this way is discharged into the tank body 21 as bubbles.

In the toilet device 100 including the sterilized water generating device 30, when gas such as hydrogen and oxygen generated in the electrolysis unit 31 is discharged as bubbles into the tank body 21 as described above, The existing water 23 containing a sterilizing component such as HClO is discharged into the tank body 21 as the bubbles move. Instead, water 23 flows from the tank body 21 into the electrolysis unit 31. The sterilizing component such as HClO discharged into the tank body 21 rises to the vicinity of the water surface along with the movement of bubbles, and then slowly descends due to its specific gravity. Thus, in addition to the circulation of the sterilizing component in the tank main body 21, the sterilizing component is diffused almost uniformly in the tank main body 21 without a driving source such as a pump due to the diffusion effect of the liquid.

In the toilet apparatus 100 including the sterilized water generating apparatus 30, it is preferable that the electrodes 311 and 312 extend in the vertical direction as shown in FIG. With this configuration, when the gas generated in the electrolysis unit 31 is desorbed from the electrode, it moves upward without touching the electrode disposed oppositely, and is thus discharged from the communication port 341 or 342 to the outside of the electrolytic cell 33. It becomes easy to be done. Therefore, a more preferable circulation effect of the water 23 is obtained, and the sterilizing component is easily diffused uniformly in the tank body 21.

Further, in the sterilized water generating system including the sterilized water generating device 30, when the electrodes 311 and 312 have a vertical positional relationship when viewed in the height direction, the upper surface portion configured to include the upper electrode. 311a (see FIG. 4 and the like) is preferably inclined upward toward the tank body 21. With this configuration, bubbles generated in the electrolysis unit 31 are easily discharged from the upper end 341a or 342a to the outside of the electrolytic cell 33. Therefore, a more preferable circulation effect of the water 23 is obtained, and the sterilizing component is easily diffused uniformly in the tank body 21.

Further, in the toilet device 100 including the sterilized water generation device 30, when the electrodes 311 and 312 have a vertical positional relationship when viewed in the height direction, the electrode 311 in the upper direction is an anode that generates oxygen. The lower electrode 312 is preferably a cathode from which hydrogen is generated. With such a configuration, bubbles with a large amount of generated hydrogen are easily detached from the cathode 312 due to the influence of buoyancy and easily discharged to the outside of the electrolytic cell 33, so that a more preferable water 23 circulation effect is obtained.

<Sterilized water generation system>
The water storage unit (wash water tank) 20 and the sterilized water generation device 30 in FIG. 1 are preferably used for toilet bowl washing, but besides that, hand washing for the purpose of preventing diseases such as colds and influenza To produce sterilized water for various uses such as washing water for washing, washing water for floors, pool and bathing water, sterilizing water for agriculture, equipment washing for medical use and food provision It can be used as a water generation system.

FIG. 2 is a schematic diagram showing a sterilized water generation system in the present embodiment. As shown in FIG. 2, the sterilized water generation system in the present embodiment includes a water storage unit 20 and a sterilized water generation device 30. The water storage unit 20 includes a tank body 21 and water 23 filled in the tank body 21.
The water storage unit 20 may be any unit that can store water discharged from the toilet device, such as a toilet bowl or a local cleaning nozzle, and may be provided separately from the cleaning water tank. For example, a tank for storing water for covering water or a tank for storing water for supplying to the local cleaning nozzle may be used. Moreover, although the water accommodating part 20 has the tank main body 21 on FIG. 2, it does not necessarily need to be a tank which stores water, What is necessary is just what can supply water. For example, the water storage unit 20 may be a water channel, and the sterilized water generation device 30 may be provided in the water channel.
In FIG. 2, the sterilized water generating device 30 is installed outside the tank main body 21, but may be provided inside the tank main body 21 as long as the water 23 can flow in and out. Good.

A preferred configuration of a sterilized water generating system including a sterilized water generating device will be described in detail below with reference to the drawings.
4 to 13 show the arrangement and configuration of the sterilized water generating device 30 in the sterilized water generating system according to the first to tenth embodiments of the present invention, and the flow direction of the generated gas and water flow in the electrolysis unit 31. It is the schematic diagram which showed.
4 to FIG. 8 according to the first to fifth embodiments in FIG. 4 to FIG. 13, the sterilized water generating device 30 is provided inside the tank body 21, whereas the sixth to tenth embodiments are the same. 9 to 13 according to the embodiment are such that the sterilized water generating device 30 is provided outside the tank main body 21. Thus, the sterilized water generating device 30 can be provided regardless of the inside or outside of the tank body 21.

FIGS. 4 and 9 are configurations of a sterilized water generating system including the sterilized water generating device 30 provided with one communication port according to the first embodiment and the sixth embodiment. As shown in FIG.4 and FIG.9, the gas flow path which connects the upper surface part 311a and the upper surface part 311a and the upper end part of a communicating port is horizontal. With this configuration, gas such as hydrogen and oxygen generated in the sterilized water generating apparatus 30 becomes bubbles and stays in the upper surface portion 311a. The bubbles staying at a certain level or more are discharged from the upper end portion of the communication port while being pushed out from the upper surface portion 311a. Along with the movement of the generated gas, the sterilized component generated in the sterilized water generating device 30 becomes a water flow and is discharged toward the upper side of the tank body 21. On the other hand, the water 23 flows from the tank body 21 into the sterilized water generator 30 through the communication port instead of the discharged gas and water flow.
By circulating the water 23 in this manner, a preferable diffusion effect of the sterilizing component can be obtained.
As in the sixth embodiment in FIG. 9, when the sterilized water generator 30 is provided outside the tank body 21, the communication port and the tank body 21 may be connected by a communication path. The communication path is preferably horizontal or inclined upward so that the generated gas is less likely to stay (hereinafter, the same applies to the seventh to tenth embodiments in which the communication path is provided).

FIG.5 and FIG.10 is a structure of the disinfection water production | generation system containing the disinfection water production | generation apparatus 30 which provided one communicating port based on 2nd Embodiment and 7th Embodiment. As shown in FIG.5 and FIG.10, the gas flow path which connects the upper-surface part 311a and a communicating port inclines upwards. With this configuration, gas such as hydrogen and oxygen generated in the sterilized water generating apparatus 30 is easily discharged from the upper surface portion 311a through the flow path to the tank body 21 through the communication path. Along with the movement of the generated gas, the sterilized component generated in the sterilized water generating device 30 becomes a water flow and is discharged toward the upper side of the tank main body 21. On the other hand, water 23 flows into the sterilized water generating device 30 from the tank body 21 instead of the exhausted gas or water flow.
By inclining the gas flow path in this way, the gas is easily discharged from the sterilized water generating apparatus 30, and a preferable circulation effect of the water 23 is obtained. Moreover, the preferable spreading | diffusion effect of disinfection component is acquired by it.

6 and 11 show the configuration of the sterilized water generation system including the sterilized water generation device 30 provided with two communication ports according to the third embodiment and the eighth embodiment. As shown in FIGS. 6 and 11, the electrodes are arranged extending in the vertical direction. Further, one of the communication ports is opened so as to communicate the water storage unit 20 and the sterilized water generating device 30 upward, and the other is opened in the horizontal direction. With this configuration, gas such as hydrogen and oxygen generated in the sterilized water generating device 30 is attached to the electrode as bubbles, and is detached from the electrode when the bubbles become a certain size or larger, so that the sterilized water generating device 30 Without staying inside, the tank is discharged upward from the communication port that opens upward. Along with the movement of the generated gas, the sterilized component generated in the sterilized water generating device 30 becomes a water flow and is discharged toward the upper side of the tank main body 21. On the other hand, instead of the discharged gas and water flow, the water 23 flows from the tank body 21 into the sterilized water generating device 30 through a communication port that opens in the horizontal direction.
In this way, the electrode is arranged so as to extend in the vertical direction, and a communication port opened upward from which the generated gas flows out and a communication port through which water 23 flows are provided separately, and the communication port opened upward However, the more preferable circulation effect of the water 23 is acquired by communicating with a water accommodating part. Thereby, a more preferable diffusion effect of the sterilizing component can be obtained.

7 and 12 show the configuration of the sterilized water generating system including the sterilized water generating device 30 provided with two communication ports according to the fourth and ninth embodiments. As shown in FIGS. 7 and 12, the electrodes are arranged extending in the vertical direction. Further, one of the communication ports opens upward and toward the outside air, and the other opens toward the horizontal direction. With this configuration, gas such as hydrogen and oxygen generated in the sterilized water generating device 30 is attached to the electrode as bubbles, and is detached from the electrode when the bubbles become a certain size or larger, so that the sterilized water generating device 30 It is discharged from the communication port that opens upward and toward the outside air without staying inside. On the other hand, instead of these discharged gases, water 23 flows from the tank body 21 into the sterilized water generating device 30 through a communication port different from the gas discharge side. Further, the sterilizing component generated in the sterilizing water generating device 30 instead of the inflowing water 23 is discharged into the tank body 21 as a water flow.
In this way, the electrodes are arranged so as to extend in the vertical direction, and a preferable circulation effect of the water 23 is provided by separately providing a communication port that opens upward and flows out of the generated gas toward the outside air, and a communication port through which the water 23 flows. Is obtained. Moreover, the preferable spreading | diffusion effect of disinfection component is acquired by it.
In such a configuration, the sterilization component is not discharged above the sterilized water generating device 30 with the movement of the generated gas as in the other configurations, but is slowly discharged due to the specific gravity after being discharged in the lateral direction. And descend. Therefore, even if the sterilized water generator 30 is disposed relatively upward, a sufficient circulation effect of the water 23 can be obtained.

8 and 13 show the configuration of the sterilized water generation system including the sterilized water generation device 30 provided with two communication ports according to the fifth embodiment and the tenth embodiment. As shown in FIGS. 8 and 13, the two communication ports are opened upward and downward, and the electrodes are arranged extending in the vertical direction. With this configuration, gas such as hydrogen and oxygen generated in the sterilized water generating device 30 is attached to the electrode as bubbles, and is detached from the electrode when the bubbles become a certain size or larger, so that the sterilized water generating device 30 Without staying inside, the tank body 21 is discharged from a communication port opened upward. Along with the movement of the generated gas, the sterilized component generated in the sterilized water generating device 30 is discharged into the tank body 21 as a water flow. On the other hand, instead of the discharged gas and water flow, water 23 flows from the tank main body 21 into the sterilized water generating device 30 through a communication port opened downward.
Thus, it is more preferable that the electrode is arranged so as to extend in the vertical direction, and a communication port opened upward from which generated gas flows out and a communication port opened downward from which water 23 flows in are separately provided. The circulation effect of water 23 is obtained. Moreover, the preferable spreading | diffusion effect of disinfection component is acquired by it.

Further, in the sterilized water generating system, the sterilized water generating device 30 is preferably disposed at a lower position when viewed in the height direction with respect to the water surface of the tank body 21. When the water 23 stored in the tank body 21 is consumed, there is a case where the water temporarily does not exist in the sterilized water generator 30 until the water is newly supplied. As described above, the sterilized water generating device 30 has a risk of failure of the device because it causes self-heating when water does not exist in the electrolysis unit 31.
