- the control unit 405 controls the bowl of the toilet 800 from the spray nozzle 480 before the user uses the toilet 800 based on the detection result of the detection unit that detects the use state of the toilet 800. Control is performed to eject water and / or sterilizing water on the surface of 801. For example, when the entrance detection sensor 402 detects that the user has entered the toilet, the control unit 405 executes control to cause the spray nozzle 480 to eject at least one of water and sterile water onto the surface of the bowl 801 of the toilet 800. Do. That is, the control unit 405 can perform control to wet the surface of the bowl 801 of the toilet bowl 800 with at least one of water and sterile water before the user uses the toilet bowl 800.
- the control unit 405 controls the use of the toilet 800 from the spray nozzle 480 after the user uses the toilet 800 based on the detection result of the detection unit that detects the use state of the toilet 800. Control is performed to eject sterile water onto the surface of the bowl 801. For example, when a predetermined time elapses after the entrance detection sensor 402 does not detect the user in the toilet room, the control unit 405 executes control to eject sterilizing water from the spray nozzle 480 to the surface of the bowl 801 of the toilet 800. . That is, the control unit 405 can execute control to wet the surface of the bowl 801 with sterile water after the user flushes the filth and finishes using the toilet 800.
- the sterilizing water is hypochlorous acid water, that is, a liquid containing hypochlorous acid will be described as an example.
- the bowl 801a of the comparative example shown in FIGS. 3 (a) to 3 (c) will be described.
- the surface of the bowl 801a of the comparative example shown in FIGS. 3A to 3C is not hydrophilic but has water repellency.
- water repellency refers to, for example, a property having a smaller affinity to water or a property of easily repelling water, as compared to the bowl surface of a toilet bowl to which glaze or the like is applied. Therefore, even if the control unit 405 ejects water or sterilizing water from the spray nozzle 480 to the surface of the bowl 801a before the user uses the toilet 800, a water film is not formed on the surface of the bowl 801a. That is, the water and the sterilizing water jetted to the surface of the bowl 801 a are condensed as, for example, water droplets and flow down to the surface of the stored water.
- Soil contains oil such as fatty acids.
- fatty acid components contained in feces include oleic acid, palmitic acid and stearic acid. Therefore, as shown in FIG. 3A, the filth 601 excreted by the user spreads over and adheres to a wider range when it hits the surface of the water-repellent bowl 801a. Subsequently, when the control unit 405 ejects hypochlorous acid water (sterilized water) 651 from the spray nozzle 480 after the user uses the toilet 800, the hypochlorous acid water 651 is shown in FIG. 3 (b). As it did, it adheres on the dirt 601 adhering to the surface of the bowl 801a.
- hypochlorous acid can decompose oil components such as fatty acids. This is confirmed by the reduction of the carbon-carbon double bond by hypochlorous acid having a concentration of 100 ppm, as in the range of the two-dot chain line A shown in FIG. This is also confirmed by the fact that the oleic acid peak is reduced by hypochlorous acid having a concentration of 100 ppm as in the range of the alternate long and two short dashes line B shown in FIG. Therefore, as shown in FIG. 3C, the hypochlorous acid water deposited on the dirt 601 can decompose the upper portion of the dirt 601 deposited on the surface of the bowl 801a.
- the contact area between the dirt 601 and the surface of the bowl 801a is larger than the case where the water film is formed on the surface of the bowl.
- the contact angle ⁇ 1 between the surface of the bowl 801a and the oil component of the dirt 601 is a water film on the surface of the bowl Less than if formed.
- “contact angle” refers to an angle formed by the solid surface and the liquid surface at the interface between a predetermined solid surface and the liquid surface and measured on the liquid side.
- hypochlorous acid water 651 can not enter the lower part of the filth 601 attached to the surface of the bowl 801 a.
- the lower part of the dirt 601 attached to the surface of the bowl 801a is not decomposed by hypochlorous acid, and may remain on the surface of the bowl 801a.
- oil such as fatty acid contained in the waste 601 may remain on the surface of the bowl 801a, and a film of the oil may be formed on the surface of the bowl 801a.
- the bacteria may be propagated.
- bacteria propagate for example, a collection of bacteria and their secretions called biofilms and the like are formed.
- biofilms and the like are formed.
- the dirt 601 hits the surface of the bowl 801 a on which the biofilm is formed, the dirt 601 may be fixed to the surface of the bowl 801 a. Then, it becomes difficult to peel off the solid component of the dirt 601 from the surface of the bowl 801 a in general toilet bowl cleaning.
- the surface of the bowl 801 of the present embodiment is hydrophilic. Therefore, as shown in FIG. 4A, the control unit 405 ejects water or sterilizing water from the spray nozzle 480 to the surface of the bowl 801 before the user uses the toilet bowl 800, whereby the user can excrete.
- a water film 653 can be formed on the surface of the bowl 801 before the dirty matter 601 hits the surface of the bowl 801.
- the oil of the filth 601 is repelled by the water film 653 or peeled off from the surface of the bowl 801 by the buoyancy of the oil itself. Thereby, it can be suppressed that the dirt 601 adheres or adheres to the surface of the bowl 801.
- the contact angle ⁇ 2 between the surface of the bowl 801 of the present embodiment and the oil component of the dirt 601 is larger than the contact angle ⁇ 1 (see FIG. 3A) when the water film is not formed on the surface of the bowl. Therefore, as shown in FIG. 4B, when the control unit 405 ejects hypochlorous acid water 651 from the spray nozzle 480 after the user uses the toilet bowl 800, the hypochlorous acid water 651 becomes a bowl. It can be deposited on the dirt 601 attached to the surface of the surface 801 and can enter or wrap around the bottom of the dirt 601. In other words, hypochlorous acid water 651 can be present to surround the oil component of the waste 601.
- hypochlorous acid can decompose the upper and lower portions of the dirt 601 attached to the surface of the bowl 801.
- the oil component of the dirt 601 attached to the surface of the bowl 801 can be efficiently decomposed, and the dirt 601 remaining on the surface of the bowl 801 can be suppressed.
- the region where the dirt 601 is not attached to the surface of the bowl 801 is the surface of the bowl It is wider than when no water film is formed. Therefore, the hypochlorous acid water 651 is more likely to adhere or fix to the area where the dirt 601 is not attached to the surface of the bowl 801, as compared with the case where the water film is not formed on the surface of the bowl. Therefore, hypochlorous acid water 651 is likely to be present to surround the oil component of the waste 601 as compared to the case where a water film is not formed on the surface of the bowl. Thereby, the oil component of the dirt 601 attached to the surface of the bowl 801 can be decomposed more efficiently.
- hypochlorous acid is used to decompose the filth 601 remaining on the surface of the bowl 801. Therefore, the generation amount of hypochlorous acid water can be suppressed. Thereby, the load of the electrolytic cell which produces hypochlorous acid water can be reduced, and it can suppress that the life of an electrolytic cell becomes short.
- the electrolytic cell for producing hypochlorous acid water will be described in detail later.
- the spray nozzle 480 can spray water or germicidal water in the form of a mist. Therefore, the water or the sterilizing water sprayed from the spray nozzle 480 adheres to a wider area of the surface of the bowl 801 uniformly. Thereby, it can be more efficiently suppressed that the dirt 601 adheres or adheres to the surface of the bowl 801.
- the sterilizing water sprayed from the spray nozzle 480 can be located around the dirt 601 remaining on the surface of the bowl 801. Therefore, the oil component of the dirt 601 attached to the surface of the bowl 801 can be decomposed more efficiently.

- the surfaces of the test pieces 810 of the samples (1) and (2) have hydrophilicity.
- the inventor jetted water to the surface of the test piece 810 before attaching the artificial dirt 601 to the test piece 810. Therefore, a water film 653 is formed on the surface of the test piece 810 of the sample (2).
- the water films 653 are scattered in the state of water droplets.
- the test piece 810a of the sample (3) (first comparative example) is formed using, for example, a photocatalyst.
- the surface of the test piece 810a formed using a photocatalyst or the like is called, for example, "superhydrophilic” or the like.
- the hydrophilicity of sample (3) is better than the hydrophilicity of sample (1).
- the pseudo soil 601 adheres to the surface of the test piece 810b of the sample (4) (second comparative example).
- a pseudo biofilm 657 is formed on the pseudo soil 601 attached to the surface of the test piece 810b.
- a biofilm is composed of a protein, an amino acid derivative and a polysaccharide.
- a biofilm 657 is formed on the surface of the test piece 810b of the sample (5) (third comparative example). Furthermore, on the biofilm 657 formed on the surface of the test piece 810b, the pseudo soil 601 is attached.
- the “removal time” of the test piece 810 (samples (1) and (2)) having hydrophilicity is the test piece 810b on which the biofilm is formed (samples (4) and (5) Shorter than the "removal time” of Therefore, it can be understood that the test piece 810 having hydrophilicity can suppress the pseudo soil 601 from adhering or adhering to the surface of the bowl 801 as compared with the test piece 810b on which the biofilm is formed. Also, the “removal time” of the sample (2) is shorter than the “removal time” of the sample (1).
- FIG. 8 is a photograph illustrating an example of the oil component of the pseudo fouling left on the surface of the test piece.
- FIG. 9 is a graph which illustrates an example of the experimental result of the nutrient survival rate which this inventor implemented.
- the present inventor made the test piece having a predetermined surface property adhere a pseudo soil containing a predetermined amount of oleic acid, and then the pseudo soil was spouted for a predetermined time, and was washed away. And this inventor measured the nutrient survival rate by the density
- the nutrient survival rate on the surface of the test piece corresponds to the growth rate of bacteria on the surface of the test piece.
- An example of the nutrient retention rate on the surface of each test piece is as shown in the graph shown in FIG.
- the photograph shown in FIG. 8 is an enlarged photograph of the surface of the sample (1) shown in FIG.
- test pieces of samples (1) and (2) have the same surface texture or hydrophilicity as the test pieces 810 of samples (1) and (2) described above with reference to FIG.
- the inventor jetted water onto the surface of the test piece before attaching the artificial dirt 601 to the test piece. Therefore, a water film 653 is formed on the surface of the test piece of the sample (2). This is similar to sample (2) described above with respect to FIG.
- the surface of the test piece of sample (3) has hydrophilicity. However, the hydrophilicity of the surface of the test piece of sample (3) is not as high as the hydrophilicity of the surfaces of the test pieces of samples (1) and (2).
- the surface properties of the test piece of the sample (3) are included in the range of the surface properties of the bowl 801 of the toilet bowl 800 of the present embodiment.

- the test piece of sample (5) (third comparative example) is similar to sample (5) (third comparative example) described above with reference to FIG. That is, a biofilm is formed on the surface of the test piece of the sample (5).
- the surface of the test piece of the sample (6) (fourth comparative example) has a water-repellent coating on a hydrophilic surface and has water repellency.
- the nutrient retention rates of the surfaces of the test pieces of the samples (1) to (3) having hydrophilicity were the same as those of the test pieces of the samples (5) and (6) having biofilm and water repellency respectively. Lower than surface nutrient retention rate. Therefore, the test pieces of the samples (1) to (3) having hydrophilicity can suppress the growth of bacteria compared to the test pieces of the samples (5) and (6) having biofilm and water repellency respectively. I understand.
- the test pieces of the samples (1) to (3) having hydrophilicity have an oil component which is a nutrient of bacteria in comparison with the test pieces of the samples (5) and (6) having the biofilm and the water repellency respectively. It can be seen that the remaining amount can be suppressed.
- the nutrient retention rate of the surface of the test piece of sample (2) is lower than the nutrient retention rate of the surface of the test piece of sample (1).

- One example of the relationship between the surface roughness Ra of the test piece and the contact angle of water with oleic acid in water is as shown in the graph of FIG.
- the surface roughness Ra is a value obtained by measuring a test piece with a surface roughness tester (Mitsutoyo Co., Ltd., compact surface roughness measuring instrument SJ-400).
- the sample (1) has the same surface texture or hydrophilicity as the test piece 810 of the sample (1) described above with reference to FIG.
