[0028] As shown in FIG. 3, the detection unit 30 includes a human body detection unit 31 and a seating detection unit 32. The human body detection unit 31 detects a user present in front of the toilet body 10. The human body detection unit 31 includes an upper detection unit and a lower detection unit. The upper detection unit detects a user present in front of the toilet body 10 when the toilet lid 12 is in a fallen state. The lower detection unit detects a user present in front of the toilet body 10 when the toilet lid 12 is in an upright state. The seating detection unit 32 detects the presence or absence of a user's seating on the toilet seat 11.

[0029] The lifting device 42 supports the casing 41 of the toilet seat device 40. The lifting device 42 is fixed to the toilet body 10. The lifting device 42 electrically raises and lowers the toilet seat device 40 based on a command from the control device 49. The lower surface of the casing 41 floats upward from the upper surface of the rear part of the toilet body 10 due to the upward movement of the toilet seat device 40.

[0030] The toilet seat 11 and the toilet lid 12 rotate and move either manually or automatically. In the manual case, the toilet seat 11 and the toilet lid 12 are pushed by the user's hand to rotate and move. In the automatic case, the toilet seat 11 and the toilet lid 12 rotate and move by the operation of the toilet seat driving device 43 and the toilet lid driving device 44. The toilet seat driving device 43 and the toilet lid driving device 44 are fixed to the casing 41. The toilet seat driving device 43 rotates the toilet seat 11 electrically based on a command from the control device 49. The toilet lid driving device 44 rotates the toilet lid 12 electrically based on a command from the control device 49. When a user approaching the vicinity of the toilet body 10 before sitting on the toilet seat 11, the toilet lid driving device 44 automatically operates to rotate the toilet lid 12 from the fallen state to the upright state. When a user rising from the toilet seat 11 leaves the toilet body 10, the toilet lid driving device 44 automatically operates to rotate the toilet lid 12 from the upright state to the fallen state.

[0031] The local cleaning device 45 cleans the user's local area based on a command from the control device 49. The local cleaning device 45 is provided with a nozzle 45A that discharges water for local cleaning. The user can operate the local cleaning device 45 at an arbitrary timing to clean the local area by operating the first operation unit 21.

[0032] The toilet cleaning device 46 supplies cleaning water to the toilet bowl part 13 through the discharge port 18 to clean the toilet bowl part 13. The toilet cleaning device 46 operates either manually or automatically. In the manual case, the toilet cleaning device 46 operates by operating either the first operation unit 21 or the second operation unit 22. The user can operate either the first operation unit 21 or the second operation unit 22 to operate the toilet cleaning device 46 at an arbitrary timing. In the automatic case, the toilet cleaning device 46 operates based on a command from the control device 49. The toilet cleaning device 46 automatically operates when the user rises from the toilet seat 11 to clean the toilet bowl part 13.

[0033] The spraying device 47 sprays mist onto a predetermined area of the toilet body 10 and the toilet seat device 40. The mist is a mist-like liquid floating in the air. The liquid is tap water, sterilized water, or the like. The liquid may be sterilized water containing hypochlorous acid or the like, a solution containing metal ions such as silver ions and copper ions, a solution containing electrolyzed chlorine and ozone, acidic water, alkaline water, or the like.

[0034] The spraying device 47 includes a nozzle 47A for spraying mist. The nozzle 47A is disposed below the toilet seat 11 in a fallen state. The nozzle 47A is provided in the vicinity of the nozzle 45A of the local cleaning device 45. The nozzle 47A is attached to the base plate of the local cleaning device 45.

[0035] The spraying device 47 sprays mist onto at least one of the first predetermined areas of the toilet body 10 and the toilet seat device 40. The first predetermined area is an area where mist is attached by the spraying device 47 under normal conditions that are not predetermined conditions. The first predetermined area is any one of the first areas. The first area is an area below the toilet lid 12 in a state where the toilet lid 12 covers the toilet bowl portion 13. The area below the toilet lid 12 in a state where the toilet lid 12 covers the toilet bowl portion 13 is an area below a virtual surface H that extends along the lid portion 12A of the fallen toilet lid 12 as shown in FIG. 2. The virtual surface H is a reference surface regardless of whether the toilet lid 12 is in an upright state or a fallen state. The area below the virtual surface H specifically includes the upper surface 16 of the rim portion 15, the inner surface 17 of the rim portion 15, the dirt receiving surface 14, the upper and lower surfaces of the fallen toilet seat 11, the lower surface of the fallen toilet lid 12, the outer surface covered by the toilet lid 12 of the toilet body 10, and the like. The first predetermined area is the entire area of the toilet bowl portion 13, the toilet bowl portion 13 and the toilet seat 11, the toilet bowl portion 13, the toilet seat 11, and the toilet lid 12, and the like.

[0036] The spraying device 47 may spray mist on the second area and the third area separately from the first predetermined area. The second area is an area where dirt is likely to scatter and adhere. Specifically, the second area is, for example, the rim portion 15 on the rear side of the toilet bowl portion 13. The third area is an area where the washing water hardly flows. Specifically, the third area is, for example, the area above the discharge port 18 of the inner surface 17 of the rim portion 15, or the area on the side opposite to the discharge port 18 of the inner surface 17 of the rim portion 15.

[0037] The spraying device 47 may be provided with a blower device. In this case, an air current can be generated inside the toilet bowl portion 13 by the blower device, and the mist can be lifted. Thereby, the spraying device 47 can spray the mist onto the toilet seat 11 and the toilet lid 12 of the toilet body 10.

[0038] The spraying device 47 operates either manually or automatically. In the manual case, the spraying device 47 operates by the operation of the first operation unit 21. The user can operate the spraying device 47 at an arbitrary timing and spray the mist by operating the first operation unit 21. In the automatic case, the spraying device 47 operates based on a command from the control device 49. The control device 49 causes the spraying device 47 to spray the mist at a preset timing. Specifically, the spraying device 47 sprays the mist before the user uses the toilet device R, after the user uses the toilet device R, and periodically regardless of whether the toilet device R is used or not. The mist sprayed before the use of the toilet device R is called pre-mist, the mist sprayed after the use of the toilet device R is called after-mist, and the mist sprayed periodically regardless of whether it is used or not is called regular mist. The manual mist, pre-mist, after-mist, and regular mist are each sprayed for a predetermined time T. The predetermined time T may be appropriately set for each mist. The predetermined time T may be different for each mist.

[0039] Some specific examples will be described regarding the control pattern of the spraying device 47 by the control device 49. When the control device 49 receives the operation signal of the mist switch of the first operation unit 21, it causes the spraying device 47 to spray the manual mist.

[0040] When the control device 49 determines, based on the detection information of the human body detection unit 31, that the user has changed from a state where the user is not detected to a state where the user is detected, the control device 49 causes the spray device 47 to spray pre-mist. The spray area of the pre-mist is an area excluding the upper surface of the toilet seat 11 and the like.

[0041] When the control device 49 determines, based on the detection information of the human body detection unit 31, that the user has changed from a state where the user is detected to a state where the user is not detected, the control device 49 causes the spray device 47 to spray after-mist. The spray area of the after-mist may cover a wide range of the toilet device R, and may include, for example, the upper surface of the toilet seat 11.

[0042] The control device 49 causes the spray device 47 to spray regular mist at a predetermined timing. The timing of the regular mist may be, for example, a predetermined day of the week or time, or may be when a predetermined time has elapsed after the end of the last mist among manual mist, pre-mist, after-mist, and regular mist. The spray area of the regular mist may be the second area and the third area. Thereby, drying of the second area and the third area can be suppressed, and adhesion of scale and dirt can be prevented.

[0043] The control device 49 sets the spraying device 47 to either the first state or the second state under predetermined conditions. In the first state, the spraying device 47 stops. The first state includes a state where the operating spraying device 47 stops immediately, a state where the operating spraying device 47 stops in a time shorter than a predetermined time T, and a state where the stopped spraying device 47 continues to stop. In the second state, mist is sprayed into a second predetermined area below the first predetermined area. The upper end of the second predetermined area is lower than the upper end of the first predetermined area. The second predetermined area may be, for example, below the dirt receiving surface 14 of the toilet bowl portion 13 or in an area close to the water surface of the toilet bowl portion 13. The means for changing the mist spraying area from the first predetermined area to the second predetermined area may be, for example, reducing the amount of liquid to be sprayed, changing the direction of the air flow of the blower device, eliminating the spraying momentum, changing the particle size of the mist, changing the mist ejection direction of the nozzle 47A, providing the nozzle 47A at the upper and lower parts of the toilet device R, and ejecting only from the lower nozzle 47A, etc.

[0044] The predetermined condition is when a person approaches near the toilet body 10. Specifically, as the predetermined conditions, there are the following condition 1, condition 2, condition 3, condition 4, condition 5, condition 6, and condition 7. Condition 1 is when the user before sitting on the toilet seat 11 approaches near the toilet body 10. Condition 2 is when the user exists near the toilet body 10 in the upright state of the toilet lid 12. Condition 3 is when the user sits on the toilet seat 11. Condition 4 is when either the toilet seat 11 or the toilet lid 12 changes from the fallen state to the upright state. Condition 5 is when the operation unit 20 is operated. Condition 6 is when the operation of the toilet cleaning device 46 is instructed. Condition 7 is when the raising of the toilet seat device 40 is instructed.

[0045] The control pattern in each condition will be described. (1) Condition 1: When the user before sitting on the toilet seat 11 approaches near the toilet body 10 As a condition 1, when the user approaches the vicinity of the toilet body 10 before sitting on the toilet seat 11 during the spraying of any one of manual mist, after mist, and regular mist, the control pattern in that case has a first control pattern, a second control pattern, and a third control pattern as shown in FIG. 4.

[0046] (1-1) First control pattern Even if the control device 49 determines based on the detection information of the human body detection unit 31 that the user has changed from a state where the user is not detected to a state where the user is detected, the toilet lid driving device 44 is not operated. The control device 49 causes the spraying device 47 to spray manual mist, after mist, and regular mist until a predetermined time T elapses. After the spraying of manual mist, after mist, and regular mist is completed, the control device 49 does not operate the toilet lid driving device 44. In the first control pattern, even if the user before sitting approaches the toilet body 10, the toilet lid 12 does not stand up. According to this configuration, during the spraying of mist, the toilet lid driving device 44 stops. As a result, it is possible to prevent the user from sitting on the toilet seat 11 during mist spraying, so that it is difficult for a person to be sprayed with mist.

[0047] (1-2) Second control pattern When the control device 49 determines based on the detection information of the human body detection unit 31 that the user has changed from a state where the user is not detected to a state where the user is detected, the control device 49 operates the toilet lid driving device 44 and sets the spraying device 47 to either the first state or the second state. In the second control pattern, the spraying time of manual mist, after mist, and regular mist becomes shorter than the predetermined time T, or the spraying area of manual mist, after mist, and regular mist changes from the first predetermined area to the second predetermined area. Therefore, when the user before sitting on the toilet seat 11 approaches the vicinity of the toilet body 10, it is possible to make it difficult for a person to be sprayed with mist.

[0048] (1-3) Third control pattern Even if the control device 49 determines that the user has changed from a state where the user is not detected to a state where the user is detected based on the detection information of the human body detection unit 31, the driving device 44 for the toilet lid is not operated, and the spraying device 47 is caused to spray manual mist, after mist, and regular mist until a predetermined time T elapses. After the spraying of the manual mist, after mist, and regular mist is finished, the control device 49 operates the driving device 44 for the toilet lid. In the third control pattern, the spraying of the mist is executed until the end of the predetermined time T. When a user approaches the toilet body 10 before sitting down, the toilet lid 12 assumes an upright state with a delay corresponding to the spraying time of the mist.

[0049] (2) Condition 2: When the user is present in the vicinity of the toilet body 10 in the upright state of the toilet lid 12 As Condition 2, the control when the next user approaches the vicinity of the toilet body 10 before the toilet lid 12 falls down during the spraying of the regular mist will be described.

[0050] During the spraying of the regular mist, if the control device 49 determines, based on the detection information of the lower detection unit of the human body detection unit 31, that the user has changed from a state where the user is not detected to a state where the user is detected, the spraying device 47 is set to either the first state or the second state.

[0051] During the spraying of the manual mist and pre-mist, if the control device 49 determines that a user who has stood up from the toilet seat 11 is present in the vicinity of the toilet body 10, the spraying device 47 may be caused to spray until the predetermined time T elapses.

[0052] (3) Condition 3: When the user sits on the toilet seat 11 During the spraying of any one of the manual mist, after mist, and regular mist, if the control device 49 determines that a user has sat on the toilet seat 11, the spraying device 47 is set to either the first state or the second state.

[0053] According to this configuration, when the user sits on the toilet seat 11, the spraying device 47 stops or sprays mist onto the second predetermined area of the toilet body 10. Therefore, it is possible to make it difficult for the mist to attach to the user's buttocks, improving usability.

[0054] During the spraying of the pre-mist, when the control device 49 determines that the user has sat on the toilet seat 11, the spraying device 47 may be allowed to spray the pre-mist until the predetermined time T elapses.

[0055] (4) Condition 4: When either the toilet seat 11 or the toilet lid 12 changes from the fallen state to the upright state Condition 4 may occur either manually or automatically. The automatic case is included in Condition 1 or Condition 5. Condition 4 will be described for the case where it manually changes from the fallen state to the upright state.

[0056] During the spraying of any of the manual mist, after-mist, and regular mist, when the control device 49 determines that either the toilet seat 11 or the toilet lid 12 has manually changed to the upright state, the spraying device 47 is set to either the first state or the second state.

[0057] According to this configuration, when either the toilet seat 11 or the toilet lid 12 manually changes from the fallen state to the upright state, the spraying device 47 stops or sprays mist onto the second predetermined area of the toilet body 10. Therefore, it is possible to make it difficult for the mist to attach to the user's hand, improving usability.

[0058] During the spraying of the pre-mist, when the control device 49 determines that either the toilet seat 11 or the toilet lid 12 has manually changed to the upright state, the spraying device 47 may be allowed to spray the pre-mist until the predetermined time T elapses.

[0059] (5) Condition 5: When the operation unit 20 is operated When the operation unit 20 is operated by a user who is not seated, it is included in condition 1. The operation of the toilet cleaning device 46 is included in condition 6. The operation of the lifting device 42 is included in condition 7. Condition 5 will be described for the case where the local cleaning device 45 is operated by a seated user.

[0060] While the control device 49 is receiving an operation signal of the local cleaning switch of the first operation unit 21 during the spraying of any one of manual mist, after mist, and regular mist, the spraying device 47 is set to either the first state or the second state. According to this configuration, it is possible to make it difficult for the user operating the operation unit 20 to be sprayed with mist.

[0061] When the control device 49 receives an operation signal of the local cleaning switch of the first operation unit 21 during the spraying of pre-mist, the spraying device 47 may be allowed to spray until a predetermined time T elapses.

[0062] (6) Condition 6: When the operation of the toilet cleaning device 46 is instructed Instructions for the operation of the toilet cleaning device 46 include manual instructions and automatic instructions. Manual instructions are made by operating the operation unit 20. Automatic instructions are made by the control device 49 determining that the user has risen from the toilet seat 11 based on the detection information of the seat detection unit 32.

[0063] Condition 6 will be described for the case where the operation of the toilet cleaning device 46 is instructed during the spraying of manual mist, pre-mist, after-mist, and regular mist. The control patterns in that case have a first control pattern, a second control pattern, a third control pattern, and a fourth control pattern as shown in FIG. 5.

[0064] (6-1) First control pattern Even if the control device 49 receives an instruction to operate the toilet cleaning device 46 during the spraying of manual mist, pre-mist, after-mist, or periodic mist, the control device 49 does not operate the toilet cleaning device 46. The control device 49 causes the spraying device 47 to spray manual mist, pre-mist, after-mist, or periodic mist until the end of a predetermined time T. After the control device 49 finishes spraying the manual mist, pre-mist, after-mist, or periodic mist, the control device 49 operates the toilet cleaning device 46. In the first control pattern, the toilet cleaning device 46 operates with a delay of the mist spraying time from the timing when the instruction to operate the toilet cleaning device 46 is given, and the toilet bowl portion 13 is cleaned.

[0065] (6-2) Second control pattern When the control device 49 receives an instruction to operate the toilet cleaning device 46 during the spraying of manual mist, pre-mist, after-mist, or periodic mist, the control device 49 operates the toilet cleaning device 46 and sets the spraying device 47 to either the first state or the second state. In the second control pattern, the spraying time of the manual mist, pre-mist, after-mist, or periodic mist becomes shorter than the predetermined time T, or the mist spraying area becomes the second predetermined area. At the timing when the instruction to operate the toilet cleaning device 46 is given, the toilet cleaning device 46 operates and the toilet bowl portion 13 is cleaned. According to this configuration, it is possible to make it difficult for the mist to attach to the user standing near the toilet main body 10.

[0066] (6-3) Third control pattern When the control device 49 receives an instruction to operate the toilet cleaning device 46 during the spraying of manual mist, pre-mist, after-mist, or periodic mist, the control device 49 operates the toilet cleaning device 46 while continuing to spray the manual mist, pre-mist, after-mist, or periodic mist with the spraying device 47. In the third control pattern, the mist spraying and the cleaning of the toilet bowl portion 13 are performed simultaneously. According to this configuration, since the toilet bowl portion 13 can be cleaned during the mist spraying, the usability can be improved.

[0067] (6-4) Fourth control pattern Even if the control device 49 receives an instruction to operate the toilet cleaning device 46 during the spraying of manual mist, pre-mist, after-mist, or regular mist, it does not operate the toilet cleaning device 46. The control device 49 causes the spraying device 47 to spray manual mist, pre-mist, after-mist, or regular mist until a predetermined time T elapses. After the control device 49 has caused the spraying device 47 to finish spraying manual mist, pre-mist, after-mist, or regular mist, it still does not operate the toilet cleaning device 46. In the fourth control pattern, the mist spraying is executed until the end of the predetermined time T. Even if there is an instruction to operate the toilet cleaning device 46, the toilet bowl section 13 is not cleaned.

[0068] (7) Condition 7: When an instruction to raise the toilet seat device 40 is given Condition 7 has a first case where an instruction to raise the toilet seat device 40 is given during mist spraying, and a second case where the timing of mist spraying occurs while the toilet seat device 40 is rising.

[0069] In the first case, when the control device 49 receives an operation signal for the raising operation of the first operation unit 21 during the spraying of any one of manual mist, pre-mist, after-mist, and regular mist, it cancels the instruction to raise the toilet seat device 40 and causes the spraying device 47 to spray until the predetermined time T elapses. While the mist is being sprayed, even if the raising operation of the first operation unit 21 is performed, the toilet seat device 40 does not rise.

[0070] In the second case, when the timing of mist spraying occurs while the toilet seat device 40 is rising, the control device 49 cancels the instruction to spray mist. This can prevent the person cleaning by raising the toilet seat device 40 from being sprayed with mist.
