    [Field of the Invention]
    [001] The present invention relates, in general, to a toilet device and, specifically, to a toilet device capable of sterilizing or washing the basin. [Fundamentals of the Invention]
    [002] When solid waste reaches the surface of the toilet bowl, fatty acid, one of the components of the stool, adheres to this surface. When a general wash of the basin is performed, on the one hand, the solid components of the stool are rinsed, but on the other, the fatty acids, etc. included in the faeces remain on the surface of the basin. In such cases, an oil film forms on its surface. Since oil is a nutrient for bacteria, if it remains on the surface of the basin, there is a risk of these bacteria proliferating. If there is a proliferation of bacteria, for example, bacteria and secretion collections called biofilms and similar ones are formed. If the biofilm is formed, the surface of the basin becomes opaque.
    [003] In addition, there are cases in which feces are attached to the basin when solid waste reaches the surface where the biofilm is formed. If this occurs, it becomes difficult to loosen the solid components of the stool by a general wash of the toilet. Thus, solid waste can remain on its surface.
    [004] On the other hand, there are toilets and seating devices that include a spout mechanism configured to release hypochlorous acid (Patent Document 1). However, if the spout mechanism, mentioned in Document 1 of the Patent, releases hypochlorous acid after the user uses the toilet, the amount of hypochlorous acid released is relatively higher. Consequently, the service life of the electrolytic cell that produces hypochlorous acid is relatively shorter. There is room for improvement on this point.
    [005] There are also localized washing devices that include a control unit for the property of released water so that the user can control the temperature of the water at the time of its release and the amount of detergent that is mixed in the released water, and a unit automatic pre-wash control system that automatically performs a pre-wash inside the basin, using a toilet spray nozzle (Patent Document 2). In the localized washing apparatus, mentioned in Document 2 of the Patent, the prescribed effects can be expected for the adhered dirt of the solid residues visibly confirmed. However, there is a risk that oils, such as fatty acids, etc., present in the faeces will remain on the surface of the basin. There is room for improvement on this point.

    [0023] A first invention is a toilet device that includes: a bowl configured to receive solid waste formed in the toilet, the bowl being hydrophilic; a spray unit configured to spray at least one selected from water and hypochlorous acid water onto the surface of the basin; a detection unit configured to detect the state of use of the toilet, and a control unit configured to control the spray unit before and after using the toilet based on the detection unit's detection result to spray at least one selected between water and water with hypochlorous acid from the spray unit before use, as well as, to spray water of hypochlorous acid from the spray unit after use.
    [0024] According to this toilet device, the basin is hydrophilic. The control unit performs a control to spray at least one selected between water and hypochlorous acid water from the spray unit before using the toilet, based on the detection result of the detection unit configured to detect the state of use of the toilet. In this way, a film of water is formed on the surface of the basin before using the toilet. Therefore, the adhesion or fixation of solid residues on the surface of the basin can be suppressed.
    [0025] In addition, the control unit performs the control of the hypochlorous acid water spray from the spray unit after using the toilet, based on the detection result of the detection unit configured to detect the state of use the toilet. Because the basin is hydrophilic, all oil from the solid residues adhered to the surface of the basin will have water with hypochlorous acid. In this way, the oils from the solid residues that remain on its surface can be decomposed efficiently, and the solid residues remaining on the surface of the basin can be suppressed. In addition, the formation of an oil coating film on the surface of the basin caused by oils from the solid residues remaining on the surface of the basin can also be suppressed. Therefore, the adhesion of solid waste and the proliferation of bacteria caused by oils from solid waste can be suppressed, and the cleanliness of the basin surface can be maintained.
    [0026] A second invention is the toilet device of the first invention, where the spraying unit is a nozzle configured to spray water and water of hypochlorous acid in a form similar to a mist.
    [0027] According to this toilet device, the mist unit is configured to spray water and hypochlorous acid water in a similar way to a mist. Therefore, water and hypochlorous acid water sprayed from the mist unit adhere evenly to a wider area of the basin surface. In this way, the adhesion or fixation of solid residues on the surface of the basin can be suppressed more efficiently. In addition, water sprayed from the sterilization unit can be positioned around the solid residues remaining on the surface of the basin. As a result, oils from solid residues adhered to the surface of the basin can be broken down more efficiently.
    [0028] A third invention is the toilet device of the first invention, where the angle of contact of oleic acid in water on the surface of the basin is not less than 90 degrees.
    [0029] According to this toilet device, the contact angle of oleic acid in the water on the surface of the basin is not less than 90 degrees. Therefore, water and hypochlorous acid water can be in all oil from solid waste. As a result, oils from solid waste will easily detach from the surface of the basin. Alternatively, oils from solid residues are easily decomposed by hypochlorous acid. In this way, the residual proportion of nutrients on the surface of the basin can be reduced. In addition, the fixation of solid waste and the proliferation of bacteria caused by oils from solid waste can be suppressed, and the cleanliness of the basin surface can be maintained.
    [0030] A fourth invention is the toilet device of the first invention in which the arithmetic mean roughness Ra of the basin surface is not greater than 0.07 µm.
    [0031] According to this toilet device, the arithmetic mean roughness Ra of the basin surface is not greater than 0.07 p.m. Thus, the angle of contact of oleic acid in the water on the surface of the basin increases. On the other hand, the angle of contact of water on the surface of the basin decreases. Therefore, a film of water can be safely formed on the surface of the basin and water and water from hypochlorous acid will be in all oil from the solid waste. Consequently, oils from solid residues are easily released from the surface of the basin. Alternatively, oils from solid residues are easily decomposed by hypochlorous acid. In this way, the residual proportion of nutrients on the surface of the basin can be reduced. In addition, the fixation of solid waste and the proliferation of bacteria caused by oils from solid waste can be suppressed, and the cleanliness of the basin surface can be maintained.
    [0032] An embodiment of the invention will be described with reference to the drawings. In the drawings, similar components are marked with the same reference numbers, and a detailed description is omitted, as appropriate.
    [0033] FIG. 1 is a schematic view illustrating the toilet device according to the embodiment of the invention.
    [0034] FIG. 2 is a block diagram illustrating the components relevant to the toilet device according to this embodiment.
    [0035] For convenience of description, in FIG. 1, the schematic view illustrating the sanitary washing device is a schematic plan view, and the schematic view illustrating the western style seat toilet is a schematic cross-sectional view. FIG. 2 illustrates simultaneously the components relevant to the water supply system and the electrical system.
    [0036] The toilet device 10 illustrated in FIG. 1 includes a western style seat toilet 800 (for convenience of the description below it will simply be called a "toilet") and a hygienic washing device 100 fitted over the western style seat toilet 800. Toilet 800 includes a basin 801. The hygienic washing device 100 includes a cabinet 400, a toilet seat 200 and a toilet lid 300. The toilet seat 200 and the toilet lid 300 are axially supported in an open and lockable manner in relation to cabinet 400. Not always it is necessary to provide the sanitary cap 300.
    [0037] Basin 801 can receive solid waste excreted by a user. The surface of basin 801 is hydrophilic. Here, in the order specification, being hydrophilic refers, for example, to having a greater affinity with water than with the surface of a basin formed by resin, such as acrylic, etc. Specifically, for example, in cases where the water contact angles are compared, a surface of the basin can be considered hydrophilic, when the surface of the basin has a contact angle less than the angle of contact of the water with the surface of the water. resin-formed basin. The hydrophilic property of the surface of basin 801 of this embodiment will be detailed below.
    [0038] For example, a spray nozzle (a spray unit) 480 configured to spray water and / or sterilization water over the surface of bowl 801 of toilet 800 is installed at the bottom of cabinet 400. The spray nozzle 480 can spray water and / or sterilization water in a similar way to mist. The spray nozzle 480 can be installed inside cabinet 400 and, in addition, it can be installed outside cabinet 400.
    [0039] Water, as referred to in the order specification, includes not only cold water, but also heated hot water. In the order specification, "sterilization water" refers to a liquid, such as hypochlorous acid or the like, which includes more sterilizing components than piped water (which is also simply called "water").
    [0040] As shown in FIG. 2, the toilet device 10 according to this embodiment, includes a first flow channel 21 that guides the water supplied by a water supply source, such as the piped water line, a water storage tank , etc. for spray nozzle 480. The solenoid valve 431 is installed on the upstream side of the first flow channel 21. The solenoid valve 431 is a solenoid valve that can open and close, and controls the water supply via a unit command. control 405 installed inside cabinet 400. The first flow channel 21 is considered to be the secondary side of the downstream side of the solenoid valve 431.
    [0041] The sterilization water production unit 450, which is capable of producing water for sterilization, is installed downstream of the solenoid valve 431. The sterilization water production unit 450 will be detailed later. A 471 flow adjustment / switching valve is installed downstream of the sterilization water production unit 450 to adjust the water intensity (flow) and to open, close and connect the water supply to the spray nozzle 480 and to the non-illustrated wash nozzle, and the like. The first flow channel 21 forks into the flow adjustment / switching valve 471. The sterilization water and the tap water, which are guided through the first flow channel 21, are guided to the spray nozzle 480, after pass through the flow adjustment / switching valve. On the other hand, the sterilization water and piped water guided to the second flow channel 23 that forks at the flow adjustment / switching valve 471 are guided, for example, to the non-illustrated washer nozzle, for the nozzle washing chamber and the like. The flow adjustment / switching valve 471 can be switched between a state in which the sterilization water and the tap water are guided to the first flow channel 21 and a state in which the sterilization water and the tap water are guided to the the second flow channel 23 based on a command from the control unit 405.
    [0042] A fourth invention is the toilet device of the first invention in which the arithmetic mean roughness Ra of the basin surface is not greater than 0.07 p.m.
    [0043] According to this toilet device, the arithmetic mean roughness Ra of the basin surface is not greater than 0.07 pm. In this way, the contact angle of oleic acid in water on the surface of the basin increases. On the other hand, the angle of contact of water on the surface of the basin decreases. Therefore, a film of water can be safely formed on the surface of the basin and water and water from hypochlorous acid will be in all oil from the solid waste. Consequently, oils from solid residues are easily released from the surface of the basin. Alternatively, oils from solid residues are easily decomposed by hypochlorous acid. In this way, the residual proportion of nutrients on the surface of the basin can be reduced. In addition, the fixation of solid waste and the proliferation of bacteria caused by oils from solid waste can be suppressed, and the cleanliness of the basin surface can be maintained.
    [0044] An embodiment of the invention will be described with reference to the drawings. In the drawings, similar components are marked with the same reference numbers, and a detailed description is omitted, as appropriate.
    [0045] FIG. 1 is a schematic view illustrating the toilet device according to the embodiment of the invention.
    [0046] FIG. 2 is a block diagram illustrating the components relevant to the toilet device according to this embodiment.
    [0047] For convenience of description, in FIG. 1, the schematic view illustrating the sanitary washing device is a schematic plan view, and the schematic view illustrating the western style seat toilet is a schematic cross-sectional view. FIG. 2 illustrates simultaneously the components relevant to the water supply system and the electrical system.
    [0048] The toilet device 10 illustrated in FIG. 1 includes a western style seat toilet 800 (for convenience of the description below it will simply be called a "toilet") and a hygienic washing device 100 fitted over the western style seat toilet 800. Toilet 800 includes a basin 801. The hygienic washing device 100 includes a cabinet 400, a toilet seat 200 and a toilet lid 300. The toilet seat 200 and the toilet lid 300 are axially supported in an open and lockable manner in relation to cabinet 400. Not always it is necessary to provide the sanitary cap 300.
    [0049] Basin 801 can receive solid waste excreted by a user. The surface of basin 801 is hydrophilic. Here, in the order specification, being hydrophilic refers, for example, to having a greater affinity with water than with the surface of a basin formed by resin, such as acrylic, etc. Specifically, for example, in cases where the water contact angles are compared, a surface of the basin can be considered hydrophilic, when the surface of the basin has a contact angle less than the angle of contact of the water with the surface of the water. resin-formed basin. The hydrophilic property of the surface of basin 801 of this embodiment will be detailed below.
    [0050] For example, a spray nozzle (a spray unit) 480 configured to spray water and / or sterilization water over the surface of bowl 801 of toilet 800 is installed at the bottom of cabinet 400. The spray nozzle 480 can spray water and / or sterilization water in a similar way to mist. The spray nozzle 480 can be installed inside cabinet 400 and, in addition, it can be installed outside cabinet 400.
    [0051] Water, as referred to in the order specification, includes not only cold water, but also heated hot water. In the order specification, "sterilization water" refers to a liquid, such as hypochlorous acid or the like, which includes more sterilizing components than piped water (which is also simply called "water").
    [0052] As illustrated in FIG. 2, the toilet device 10 according to this embodiment, includes a first flow channel 21 that guides the water supplied by a water supply source, such as the piped water line, a water storage tank , etc. for spray nozzle 480. The solenoid valve 431 is installed on the upstream side of the first flow channel 21. The solenoid valve 431 is a solenoid valve that can open and close, and controls the water supply via a unit command. control 405 installed inside cabinet 400. The first flow channel 21 is considered to be the secondary side of the downstream side of the solenoid valve 431.
    [0053] The sterilization water production unit 450, which is capable of producing water for sterilization, is installed downstream of the solenoid valve 431. The sterilization water production unit 450 will be detailed later. A 471 flow adjustment / switching valve is installed downstream of the sterilization water production unit 450 to adjust the water intensity (flow) and to open, close and connect the water supply to the spray nozzle 480 and to the non-illustrated wash nozzle, and the like. The first flow channel 21 forks into the flow adjustment / switching valve 471. The sterilization water and the tap water, which are guided through the first flow channel 21, are guided to the spray nozzle 480, after pass through the flow adjustment / switching valve. On the other hand, the sterilization water and piped water guided to the second flow channel 23 that forks at the flow adjustment / switching valve 471 are guided, for example, to the non-illustrated nozzle, to the chamber nozzle washing and the like. The flow adjustment / switching valve 471 can be switched between a state in which the sterilization water and the tap water are guided to the first flow channel 21 and a state in which the sterilization water and the tap water are guided to the the second flow channel 23 based on a command from the control unit 405.
    [0054] For example, a detection unit configured to detect the state of use of toilet 800 is installed in cabinet 400. More specifically, a bathroom entry detection sensor (a detection unit) 402 configured to detect entry user in the bathroom, a human body detection sensor (a detection unit) 403 configured to detect the user in front of the seat 200 and a seat contact detection sensor (a detection unit) 404 configured to detect the user seated on seat 200 are installed in cabinet 400.
    [0055] The bathroom entrance sensor 402 can detect the user immediately after opening the door and entering the bathroom or the user present in front of the door to enter the bathroom. That is, the bathroom entrance sensor 402 can detect not only a user who entered the bathroom, but also a user before entering the bathroom, that is, a user present in front of the door outside the bathroom. A pyroelectric sensor, a microwave sensor such as a Doppler sensor, and the like can be used as an entry detection sensor in bathroom 402. In the case of a sensor that uses the microwave Doppler effect, a sensor configured to transmit micro and to detect the object to be detected based on the amplitude (intensity) of the reflected microwave, or a similar one is used, it is possible to detect the presence of the user through the bathroom door. That is, the user can be detected before entering the bathroom.
    [0056] The human body detection sensor 403 can detect the user in front of the toilet 800, that is, the user present in a position in front of the seat 200 and distant to the lid 200. That is, the body detection sensor human 403 can detect a user who has entered the bathroom and approaches seat 200. For example, an infrared transmit and receive distance sensor and the like can be used as a 403 human body detection sensor.
    [0057] The seat contact detection sensor 404 can detect a user sitting on seat 200 or a human body present above seat 200 just before the user sits on seat 200. In other words, the contact detection sensor of seat 404 can detect not only a user sitting on seat 200, but also a user present above seat 200. For example, an infrared transmit and receive distance sensor and the like can be used as a seat contact detection sensor 404.
    [0058] FIG. 3A to FIG. 3C are seen in schematic cross section illustrating the surface of a basin according to a comparative example.
    [0059] FIG. 4A to FIG. 4C are seen in schematic cross section illustrating the surface of the basin according to this embodiment.
    [0060] FIG. 5 to FIG. 6 are graphs that illustrate the decomposition effects of hypochlorous acid.
    [0061] In the toilet device 10, in accordance with this embodiment, the control unit 405 performs the control to spray at least one selected between water and sterilization water on the surface of basin 801 of toilet 800 from of the spray nozzle 480 before the user uses toilet 800 based on the detection result of the detection unit that detects the state of use of toilet 800. For example, when the toilet entrance detection sensor 402 detects the entrance in the bathroom, the control unit 405 performs the control to spray at least one selected from water and sterilization water onto the surface of basin 801 of toilet 800 from spray nozzle 480. That is, the control unit 405 can perform a control to wet the surface of basin 801 of toilet 800 with at least one selected from water and sterilization water before the user uses toilet 800.
    [0062] In addition, in the toilet apparatus 10 according to this embodiment, the control unit 405 performs a control to spray sterilization water on the surface of the basin 801 of the toilet 800 from the spray nozzle 480 , after the user uses toilet 800, based on the detection result of the detection unit that detects the state of use of toilet 800. For example, the control unit 405 performs the control to spray the sterilization water over the surface of basin 801 of toilet 800 from spray nozzle 480, when a prescribed amount of time has elapsed since the toilet entrance detection sensor 402 no longer detects the user's presence in the bathroom. That is, the control unit 405 can perform the control to wet the surface of basin 801 with the sterilization water after the user has flushed and finished using toilet 800. In the description mentioned below, when the sterilization water is hypochlorous acid water, that is, a liquid including hypochlorous acid, is described as an example.
    [0063] Bowl 801a of the comparative example of FIG. 3A to FIG. 3C will now be described.
    [0064] The surface of basin 801a of the comparative example illustrated in FIG. 3A to FIG. 30 is not hydrophilic, but is water-repellent. Here, “water repellent” in the order specification, for example, refers to the property of having a lower water affinity than that of the basin surface provided with an enamel or similar, or the property of repelling water easily. Therefore, a film of water is not formed on the surface of the basin 801a, even in the case where the control unit 405 causes water and / or sterilization water to be sprayed on the surface of the basin 801a from the nozzle. spray 480 before the user uses toilet 800. That is, the water and / or sterilization water that is sprayed on the surface of basin 801a is grouped together, for example, as drops of water and the like, and flows downwards to the accumulated water surface.
    [0065] Solid residues (feces) include oils, such as fatty acids, etc. For example, oleic acid, palmitic acid, stearic acid and the like are examples of the fatty acid components included in stool. Therefore, as illustrated in FIG. 3A, the solid waste 601 excreted by the user is spread over a wide area and adheres when it collides with the water repellent surface of the basin 801a. Continuing, when the control unit 405 causes the water of hypochlorous acid (sterilizing water) 651 to be sprayed from the spray nozzle 480 after the user uses toilet 800, the water of hypochlorous acid 651 adheres to the waste solids 601 which are adhered to the surface of the basin 801a, as illustrated in FIG. 3B.
    [0066] Here, as a result of research by the inventor, it has been proven that hypochlorous acid can decompose oils, such as fatty acids, etc. In the region marked with line type dot dot dash A illustrated in FIG. 5, this is confirmed by the reduction of carbon-carbon double bonds, due to the hypochlorous acid having a concentration of 100 ppm. Also, just like in the region marked with line type dot dot dash B illustrated in FIG. 6, it was confirmed that the peak of oleic acid decreases due to the hypochlorous acid having a concentration of 100 ppm.
    [0067] Therefore, as illustrated in FIG. 30, the hypochlorous acid water adhered to solid residues 601 can decompose the upper portion of solid residues 601 adhered to the surface of basin 801a.
    [0068] However, as the water film is not formed on the surface of the basin 801a, the area of the contact surface between the solid waste 601 and the surface of the basin 801a is greater than that of the case in which the water film water is formed on the surface of the basin. In addition, since the surface of the basin 801a is water-repellent and the water film is not formed on the surface of the basin 801a, a contact angle 61 between the surface 801a of the basin and the oils from solid waste 601 is less than that of the case in which the water film is formed on the surface of the basin. Here, "contact angle" in the order specification, refers to the angle between a prescribed solid surface and the liquid surface at the interface between the solid surface and the liquid surface, and is the angle measured on the liquid side. .
    [0069] Therefore, water of hypochlorous acid 651 cannot reach the lower portion of solid residues 601 adhered to the surface of basin 801a. Thus, as illustrated in FIG. 3C, there is a risk that the lower portion of solid residues 601 adhered to the surface of basin 801a cannot be decomposed by hypochlorous acid and may remain on the surface of basin 801a. Alternatively, there is a risk that oils, such as fatty acids, etc. included in solid waste 601 may remain on the surface of the basin 801a, and an oil coating film may form on the surface of the basin 801a.
    [0070] As oils become nutrients for bacteria, there is a risk that they can proliferate if the oils remain on the surface of basin 801a. If there is a proliferation of bacteria, for example, bacteria and secretion collections called biofilms and similar ones are formed. When solid waste 601 reaches the surface of basin 801a, where a biofilm is formed, there are cases where solid waste 601 attaches to the surface of basin 801a. If this occurs, it becomes difficult to detach the solid components from solid waste 601 from the surface of basin 801a with a general wash of the toilet.
    [0071] On the other hand, the surface of basin 801 of this embodiment is hydrophilic. Therefore, as illustrated in FIG. 4A, a water film 653 can be formed by the control unit 405 on the surface of the basin 801 before the solid waste 601 excreted by the user reaches the surface of the basin 801, causing water and / or sterilization water to be sprayed on the surface from basin 801 from spray nozzle 480 before user uses toilet 800. The oils from solid residues 601 come off the surface of basin 801 when repelled by water film 653 or the floatability of the oil itself. In this way, the adhesion or fixation of solid residues 601 on the surface of the basin 801 can be suppressed.
    [0072] Even in the case where solid waste 601 remains on the surface of basin 801, as illustrated in FIG. 4A, oils from solid waste 601 are repelled by water film 653 because water film 653 is formed on the surface of basin 801. Therefore, a contact angle 62 between the surface of basin 801 and oils from solid waste 601 of this embodiment is greater than a contact angle 61 (referred to in FIG. 3A) of the case where the water film is not formed on the surface of the basin. Therefore, as illustrated in FIG. 4B, when the control unit 405 causes the water of hypochlorous acid 651 to be sprayed from the spray nozzle 480 after the user uses toilet 800, and thus, the water of hypochlorous acid 651 adheres to solid waste 601 which are adhered to the surface of basin 801 and reach or extend around the lower portion of solid waste 601. In other words, water from hypochlorous acid 651 can be in all the oil from solid waste 601.
    [0073] Therefore, as illustrated in FIG. 40, hypochlorous acid can decompose the upper and lower portions of solid residues 601 adhered to the surface of basin 801. In this way, oils from solid residues 601 adhered to the surface of basin 801 can be decomposed efficiently, and residues solids 601 remaining on the surface of basin 801 can be suppressed. In addition, the formation of the oil coating film on the surface of the basin 801, because the oils from the solid residues 601 remain on the surface of the basin 801 can be suppressed. Therefore, the fixation of solid waste 601 and the proliferation of bacteria caused by oils from solid waste 601 can be suppressed, and the cleanliness of the surface of basin 801 can be maintained.
    [0074] Furthermore, because the adhesion of solid waste 601 on the surface of basin 801 is suppressed by the water film 653 formed on the surface of basin 801, the region in which solid waste 601 is not adhered to the surface of basin 801 is greater than that of the case where the water film is not formed on the surface of the basin. Therefore, water of hypochlorous acid 651 adheres or attaches more easily to the region where solid waste 601 does not adhere to the surface of basin 801, than in the case where the water film is not formed on the surface of the basin. Therefore, hypochlorous acid water 651 will be around the oils from solid waste 601 more easily than in the case where the water film is not formed on the surface of the basin. In this way, oils from solid residues 601 adhered to the surface of basin 801 can be decomposed more efficiently.
    [0075] Hypochlorous acid is used to decompose solid residues 601 that remain on the surface of basin 801. Therefore, the volume of water production of hypochlorous acid can be decreased. Thus, the charge of the electrolytic cell that produces the hypochlorous acid water can be reduced and the shorter service life of the electrolytic cell can be suppressed. The electrolytic cell that produces the hypochlorous acid water will be detailed later.
    [0076] Also, as previously described with respect to FIG. 1 and FIG. 2, the spray nozzle 480 can spray water and / or sterilization water in a mist-like manner. Therefore, the water and / or sterilization water sprayed by the spray nozzle 480 adheres evenly over a wider area of the surface of the basin 801. In this way, the adhesion or fixation of solid residues 601 on the surface of the basin 801 can be suppressed more efficiently. In addition, the sterilization water sprayed from the spray nozzle 480 can be positioned around the solid residues 601 that remain on the surface of the basin 801. Therefore, the oils from the solid residues 601 adhered to the surface of the basin 801 can be decomposed more efficiently.
    [0077] An example of the results of experiments carried out by the inventor will now be described with reference to the drawings.
    [0078] FIG. 7 is a table of results that illustrates an example of the results of experiments carried out by the inventor for the time of removal of solid waste.
    [0079] The inventor causes adherence of pseudo-solid residues to test pieces that have properties of the prescribed surface, and then rinse them. Pseudo-solid waste included oleic acid, which is a component of solid waste, and had properties that approximate solid waste. The inventor photographed the surface of each of the test pieces after washing the pseudo-solid waste. The inventor measured the time required to remove the solid pseudo-residues adhered to the test piece for each of the test pieces. The surface photographs illustrated in FIG. 7 are examples of the surface of the test pieces. The removal times (in seconds) shown in FIG. 7 are examples of the time required to remove the pseudo-solid residues 601 adhered to the test pieces.
    [0080] The surfaces of test pieces 810 were hydrophilic for samples (1) and (2). For test piece 810 of the sample (2), the inventor sprayed water on the surface of test piece 810 before making pseudo-solid residues 601 adhere to test piece 810. Therefore, water film 653 was formed on the surface of test piece 810 of the sample (2). In the state of the surface illustrated in FIG. 7 for test piece 810 of the sample (2), the water film 653 is in a state of water droplets.
    [0081] A test piece 810a of the sample (3) (the first comparative example) was formed using, for example, a photocatalyst and the like. The surface of test piece 810a formed using a photocatalyst and the like is called, for example, “super-hydrophilic”. Thus, the sample (3) was more hydrophilic than the sample (1). The pseudo-solid residues 601 were adhered to the surface of a test piece 810b of the sample (4) (the second comparative example). Also, a pseudo-biofilm 657 was formed on the pseudo-solid residues 601 adhered to the surface of test piece 810b. Biofilms were made of proteins, derived from amino acids and polysaccharides. Therefore, they can be replaced by a commercial gum syrup that includes proteins, derivatives of amino acids and polysaccharides, and the gum syrup has been covered and evaluated as pseudo-biofilm (for convenience of the description below, the pseudo-biofilm is simply called biofilm). Biofilm 657 was formed on the surface of test piece 810b of the sample (5) (the third comparative example). Then, pseudo-solid residues 601 adhered to biofilm 657 formed on the surface of test piece 810b.
    [0082] According to the results of this experiment, the removal time of the 810 test pieces that were hydrophilic (samples (1) and (2)) was less than the removal time of the 810b test pieces (samples (4 ) and (5)) in which biofilms were formed. Therefore, it can be seen that the adherence or fixation of the solid pseudo-residues 601 on the surface of the basin 801 can be better suppressed in test pieces 810 which were hydrophilic than in test pieces 810b in which biofilms were formed. Also, the sample removal time (2) was shorter than the sample removal time (1). Therefore, it can be seen that the adherence or fixation of the solid pseudo-residues 601 on the surface of test piece 810 can be suppressed and the removal time can also approach test piece 810a (sample (3)) which has been super- hydrophilic, causing water to be sprayed onto the surface of test piece 810 before pseudo-solid waste 601 touches the surface of test piece 810.
    [0083] In the case where biofilm 657 was formed in solid waste 601, as shown in the sample surface photograph (4), pseudo-solid waste 601 remained in test piece 810b even after pseudo-solid waste 601 was rinsed for 294 seconds. Therefore, it can be observed that it is difficult to rinse the solid pseudo-waste 601 if biofilm 657 is formed.
    [0084] FIG. 8 is a photograph illustrating an example of oil from the remaining pseudo-solid residues on the surface of the test piece.
    [0085] FIG. 9 is a graph that illustrates an example of the results of experiments carried out by the inventor for the residual proportion of nutrients.
    [0086] The inventor caused pseudo-solid residues containing a prescribed amount of oleic acid to adhere to the test pieces, whose surfaces had prescribed and subsequently properties, sprayed with water for a prescribed time, and flushed. Then, the inventor measured the residual proportion of nutrients, after discharging the pseudo-solid residues, measuring the concentration of oleic acid that remained on the surfaces of the test pieces.
    [0087] As illustrated in FIG. 8, even with the discharge of the pseudo-solid residues, the oils of the pseudo-solid residues remained on the surface of the test piece. The inventor measured the concentration of the nutritional components, that is, the residual proportion of nutrients included in the oils of the pseudo-solid residues that remained on the surface of the test piece. The residual proportion of nutrients on the test piece surface corresponds to the rate of growth of bacteria on the test piece surface. Examples of residual proportions of nutrients from the surfaces of the test pieces are as illustrated in the graph of FIG. 9. The photograph of FIG. 8 is an enlarged photograph of the sample surface (1) shown in FIG. 9.
    [0088] The surfaces of the test pieces of the samples (1) and (2) are hydrophilic, that is, they have properties similar to the test pieces 810 of the samples (1) and (2) described above with respect to FIG. 7. For the test piece of the sample (2), the inventor sprayed water on the surface of the test piece before causing the pseudo-solid residues 601 to adhere to the test piece. Therefore, a film of water 653 formed on the surface of the sample test piece (2). This is similar to the sample (2) described above with respect to FIG. 7.
    [0089] The surface of the sample test piece (3) was hydrophilic. However, the surface of the sample test piece (3) was not hydrophilic like the surfaces of the sample test pieces (1) and (2). The surface property of the sample test piece (3) is within the range of the surface property of the basin 801 of the toilet 800 of this embodiment.
    [0090] The test piece of the sample (4) (the first comparative example) was similar to that of the sample (3) (the first comparative example) previously described with respect to FIG. 7. That is, the surface of the sample test piece (4) was super-hydrophilic. The test piece of the sample (5) (the third comparative example) was similar to the sample (5) described above with respect to FIG. 7. That is, a biofilm was formed on the surface of the sample test piece (5). The surface of the sample test piece (6) (the fourth comparative example) had a waterproof coating film on a hydrophilic surface and was water-repellent.
    [0091] According to the results of this experiment, the residual proportions of nutrients on the surfaces of the test pieces of the samples (1) to (3) that were hydrophilic, were lower than the residual proportions of nutrients on the surfaces of the test pieces of samples (5) and (6), which had a biofilm and were water repellent, respectively. Therefore, it can be seen that the proliferation of bacteria can be suppressed more in the test pieces of the samples (1) to (3) that were hydrophilic than in the test pieces of the samples (5) and (6) that had a biofilm and were water-repellent, respectively. In addition, it can also be observed that the residual amount of oil that becomes a nutrient for bacteria can be better suppressed in the test pieces of the samples (1) to (3) that were hydrophilic than in the test pieces of the samples ( 5) and (6) that had a biofilm and were water repellent, respectively.
    [0092] In addition, the residual proportion of nutrients on the surface of the sample test piece (2) was less than the residual proportion of nutrients on the surface of the sample test piece (1). Therefore, it can be observed that the proliferation of bacteria on the surface of the test piece can be suppressed, being able to approach the residual proportion of nutrients on the surface of the test piece (of the sample (4)) that was super-hydrophilic, causing the water is sprayed on the test piece surface before the pseudo-solid residues 601 touch it.
    [0093] The residual proportion of nutrients on the surface of the sample test piece (5) was higher than the residual proportion of nutrients on the surface of the sample test piece (6). Therefore, it can be observed that it is difficult to suppress the proliferation of bacteria if the biofilm is formed, as on the surface of the sample test piece (5).
    [0094] FIG. 10 is a graph that illustrates an example of the results of experiments carried out by the inventor for the residual proportion of nutrients and the angle of contact of oleic acid in water.
    [0095] FIG. 11 is a graph that illustrates an example of the results of experiments carried out by the inventor for the years of accelerated aging and the angle of contact in water of oleic acid.
    [0096] The contact angle in the water was measured using a contact angle meter (automatic contact angle meter DM-500 manufactured by Kyowa Interface Science Co., Ltd.) by immersing the test piece in a water tank in a state in which oleic acid had been dripped onto the test piece, by measuring the contact angle between oleic acid and the test piece in this state.
    [0097] The inventor measured the relationship between the residual proportion of nutrients and the angle of contact of oleic acid in water to the surface of the test piece. Here, “water contact angle” in the order specification refers to the angle in contact with water. The contact angle in water of oleic acid, which is a component of the fatty acids included in faeces, is different from the contact angle in air. As previously described with reference to FIG. 4A to FIG. 4C, the water film 653 is formed by the control unit 405 of the present embodiment, causing water and / or sterilization water to be sprayed onto the surface of bowl 801 of toilet 800 before the user uses the toilet 800. Therefore, the inventor considered that the assessment of the contact angle of oleic acid in water was more appropriate than the assessment of the contact angle of oleic acid in the air. The method for measuring the residual proportion of nutrients on the test piece surface is as described above with respect to FIG. 8 and FIG. 9.
    [0098] An example of the relationship between the residual proportion of nutrients and the contact angle of oleic acid in water to the surface of the test piece is as illustrated in the graph of FIG. 10. The surfaces of the test pieces of the samples (1) and (2) were hydrophilic, that is, they had surface properties similar to those of the test piece 810 of the sample (1) described previously with respect to FIG. 7. The surface of the sample test piece (2) was not as hydrophilic as the surface of the sample test piece (1). The surface property of the sample test piece (2) was within the range of the surface property of bowl 801 of toilet 800 of this embodiment.
    [0099] The test piece of the sample (3) (the first comparative example) was similar to that of the sample (3) (the first comparative example) previously described with reference to FIG. 7. That is, the surface of the sample test piece (3) was super-hydrophilic. The test piece of the sample (4) (the fourth comparative example) was similar to the sample (6) (the fourth comparative example) described above with respect to FIG. 9. That is, the surface of the sample test piece (4) was water-repellent. The surface of the sample test piece (5) (the fifth comparative example) was made of an acrylic resin and was water-repellent.
    [00100] An example of the contact angle of oleic acid in water to the surface of the test piece of the sample (1) was, for example, about 123.9 degrees. An example of the contact angle of oleic acid in water to the surface of the test piece of the sample (2) was, for example, about 106.0 degrees. An example of the contact angle of oleic acid in water to the surface of the test piece of the sample (3) was, for example, about 169.4 degrees. An example of the contact angle of oleic acid in water to the surface of the test piece of the sample (4) was, for example, about 33.1 degrees. An example of the contact angle of oleic acid in water to the surface of the test piece of the sample (5) was, for example, about 2.5 degrees.
    [00101] It can be seen that, according to the results of this experiment, the residual proportion of nutrients decreases as the angle of contact of oleic acid in the water increases. As previously described with reference to FIG. 4A to FIG. 4C, this is due to the fact that water and / or sterilization water may be in all the oil from solid residues 601 in the event that the angle of contact of oleic acid in the water is greater. Therefore, the ease of loosening oils from solid residues 601 on the surface of the test piece increases as the angle of contact of oleic acid in the water increases. Alternatively, the area of the contact surface between oleic acid and the test piece decreases in the case where the angle of contact of oleic acid in water is greater. Therefore, oils from solid residues 601 are more effectively decomposed and are more easily released with water from hypochlorous acid 651 when the angle of contact of oleic acid in water increases. Thus, it can be seen that the proliferation of bacteria can be suppressed for the test pieces (samples (1) and (2)) that are hydrophilic and for those whose contact angles of oleic acid in the water on the surface are large . Therefore, it is desirable that the contact angle of oleic acid in water on the surface of basin 801 be greater.
    [00102] Here, the surface property of basin 801 of toilet 800 changes due to the number of years of use of toilet 800. More specifically, the contact angle of oleic acid in the water on the surface of basin 801 changes due to the number of years of use of the toilet 800. The inventor implemented an accelerated aging test and measured the relationship between the years of accelerated aging and the contact angle of oleic acid in water.
    [00103] First, the inventor prepared a solution of sodium hydroxide (NaOH) with a mass percentage of 5% by weight. Continuing, the inventor defined the sodium hydroxide solution that was prepared at 70 ° C and immersed the test pieces in the solution. When a test piece was submerged for one hour in the sodium hydroxide solution, which was prepared under these conditions, it corresponded to the test piece (toilet 800) used for one year.
    [00104] An example of the relationship between the years of accelerated aging and the contact angle of oleic acid in water is as illustrated in the graph of FIG. 11. The samples (1) to (5) illustrated in FIG. 11 correspond to the samples (1) to (5) described above with respect to FIG. 10, respectively. Like the graph in FIG. 11, it can be seen that the contact angles of oleic acid in water to the surfaces of the test pieces of the samples (2) and (3) decrease from the initial state (years of accelerated aging: 0 years). It can be seen that for the surface of the sample test piece (4), the contact angle of oleic acid in the water increases once from the initial state (years of accelerated aging: 0 years) and subsequently decreases as the years of accelerated aging go from 5 years to 10 years. This is considered to be because the water-repellent coating film on the surface is removed and the hydrophilic surface under that water-repellent coating film is exposed. It can be observed that, for the surfaces of the test pieces of the samples (1) and (5), the contact angles of the oleic acid in the water are substantially maintained in the initial state (years of accelerated aging: 0 years).
    [00105] The contact angles of oleic acid in water illustrated in FIG. 10 are the contact angles of oleic acid in the water of the test piece surfaces in the initial state (years of accelerated aging: 0 years). In considering this, it is desirable that the contact angle of oleic acid in water is not less than about 90 degrees in the initial state. In addition, it is more desirable that the contact angle of oleic acid in water is not less than about 110 degrees and even more desirable that it is not less than about 120 degrees in the initial state. In this way, hypochlorous acid water 651 can be present around the oils from solid waste 601. Therefore, oils from solid waste 601 adhered to the surface of basin 801 can be decomposed efficiently. In addition, the fixation of solid waste 601 and the proliferation of bacteria caused by oils from solid waste 601 can be suppressed, and the cleanliness of the surface of basin 801 can be maintained.
    [00106] FIG. 12 is a graph that illustrates an example of the results of experiments carried out by the inventor for the surface roughness and the angle of contact of oleic acid in water.
    [00107] The inventor measures the relationship between the surface roughness Ra (the arithmetic mean of the roughness Ra) and the contact angle of oleic acid in water for the test pieces. An example of the relationship between the surface roughness Ra and the contact angle of oleic acid in water for the test pieces is as illustrated in the graph of FIG. 12.
    [00108] The surface roughness Ra is a measured value of the test pieces, using a surface roughness meter (portable roughness measuring instrument SJ-400 manufactured by Mitutoyo Corporation).
    [00109] The sample (1) was hydrophilic, that is, it had a surface property similar to that of test piece 810 of the sample (1) described previously with respect to FIG. 7. The test piece of the sample (2) (the first comparative example) was similar to the sample (3) (the first comparative example) described above with respect to FIG. 7. That is, the surface of the sample test piece (2) was super-hydrophilic. The test piece of the sample (3) (the fourth comparative example) was similar to that of the sample (6) (the fourth comparative example) described above with respect to FIG. 9. That is, the surface of the sample test piece (3) was water-repellent. The test piece of the sample (4) (the fifth comparative example) was similar to that of the sample (5) (the fifth comparative example) previously described with respect to FIG. 10 and FIG. 11. That is, the surface of the sample test piece (4) was water-repellent.
    [00110] It can be observed that, according to the results of this experiment, there is a correlation between the surface roughness Ra and the contact angle of oleic acid in the water for the test piece (sample (1)) that was hydrophilic. More specifically, it can be seen that there is a tendency for the angle of contact of oleic acid in water to increase as the surface roughness Ra decreases for the test piece (sample (1)) which is hydrophilic.
    [00111] When considering the contact angles of oleic acid in water, previously described with respect to FIG. 10 and FIG. 11 and the example of the relationship between the surface roughness Ra and the contact angle of oleic acid in water illustrated in FIG. 12, it is desirable that the surface roughness of basin 801 should not exceed about 0.07 p.m (microns). In addition, it is more desirable that the surface roughness of basin 801 is not more than about 0.04 pm. Thus, water from hypochlorous acid 651 can be present in all oil from solid waste 601. Therefore, oils of solid waste 601 adhered to the surface of basin 801 can be decomposed efficiently. In addition, the fixation of solid waste 601 and the proliferation of bacteria caused by oils from solid waste 601 can be suppressed, and the cleanliness of the surface of basin 801 can be maintained.
    [00112] A specific example of the sterilization water production unit 450 of this embodiment will now be described with reference to the drawings.
    [00113] FIG. 13 is a schematic cross-sectional view illustrating the specific example of the sterilization water production unit of this embodiment.
    [00114] The sterilization water production unit 450 of this embodiment is, for example, an electrolytic cell unit that includes an electrode.
    [00115] As illustrated in FIG. 13, the sterilization water production unit 450 of the present specific example, includes an anode plate 451 and a cathode plate 452 inside the sterilization water production unit 450 and can electrolyze the running water flowing inside it through a conduction control of the control unit 405. Here, the tap water includes chlorine ions. These chlorine ions are included in water sources (for example, groundwater, dam water, river water and the like) such as common salt (NaCI) and calcium chloride (CaCh). Therefore, hypochlorous acid is produced by electrolysing chlorine ions. As a result, water that has been electrolyzed (electrolyzed water) by the sterilization water production unit 450 converts to hypochlorous acid water.
    [00116] Hypochlorous acid works as a sterilization component, and hypochlorous acid water, that is, sterilization water, can efficiently sterilize dirt due to ammonia and the like by removal or decomposition. In addition, hypochlorous acid water, as described above, can break down oils, such as fatty acids, etc., included in faeces.
    [00117] According to this embodiment as described above, the surface of bowl 801 of toilet 800 is hydrophilic. The control unit 405 performs a control to make at least one selected between water and sterilization water sprayed on the surface of basin 801 of toilet 800 from spray nozzle 480 before the user uses toilet 800 , based on the detection result of the detection unit that detects the state of use of toilet 800. In addition, the control unit 405 performs a control so that the sterilization water is sprayed on the surface of basin 801 of the toilet toilet 800 from the spray nozzle 480 after the user uses toilet 800, based on the detection result of the detection unit that detects the state of use of toilet 800. In this way, the adhesion or fixation of solid waste 601 on the surface of basin 801 can be suppressed. In addition, oils from solid residues 601 adhered to the surface of basin 801 can be decomposed efficiently, and solid residues 601 remaining on the surface of basin 801 can be suppressed. In addition, the formation of an oil film coating on the surface of the basin 801 due to the oils from solid residues 601 remaining on the surface of the basin 801 can be suppressed. Therefore, the fixation of solid waste 601 and the proliferation of bacteria caused by oils from solid waste 601 can be suppressed, and the cleanliness of the surface of basin 801 can be maintained.
    [00118] Earlier in this document, embodiments of the invention have been described. However, the invention is not limited to these descriptions. Appropriate design modifications carried out by a person skilled in the art concerning the embodiments described above are also within the scope of the invention insofar as the characteristics of the invention are included.
