[0020] The toilet seat 11 and toilet lid 12 rotate to a reclined state, where they are aligned with the upper surface 16 of the toilet bowl body 10, and an upright state, where they are standing above the upper surface of the toilet bowl body 10. The toilet lid 12 has a lid portion 12A and a peripheral edge portion 12B. In the reclined state of the toilet lid 12, the lid portion 12A covers the upper surface of the toilet seat 11, and the peripheral edge portion 12B covers the outer circumferential surface of the toilet seat 11 (see Figure 2).

[0021] As shown in Figure 2, the toilet bowl body 10 includes a toilet bowl section 13. The toilet bowl section 13 has a waste receiving surface 14 for receiving waste. Water is stored in the toilet bowl section 13. The toilet bowl section 13 is covered on the upper side by a toilet lid 12 in an inverted state.

[0022] The upper edge of the toilet bowl portion 13 is a rim portion 15. In plan view, the rim portion 15 is annular in shape. The rim portion 15 has an upper surface 16 and an inner surface 17. The upper surface 16 of the rim portion 15 faces the lower surface of the toilet seat 11 when it is in an inverted position. The inner surface 17 of the rim portion 15 is continuous with the upper side of the waste receiving surface 14. The inner surface 17 of the rim portion 15 rises at a more vertical angle than the waste receiving surface 14.

[0023] The rim portion 15 is provided with a discharge port 18 for discharging cleaning water. The discharge port 18 is located on the rear side of the toilet bowl portion 13. The cleaning water discharged from the discharge port 18 flows along the inner surface 17 of the rim portion 15 and swirls around the toilet bowl portion 13.

[0024] As shown in Figure 2, the toilet seat unit 40 is positioned on the rear upper surface of the toilet bowl body 10. The toilet seat unit 40 can be raised or lowered from the top surface of the toilet bowl body 10 either manually or electrically. To manually raise the toilet seat unit 40, the user presses the locking mechanism 23 (see Figure 1) on the toilet seat unit 40 to release the lock and then lifts the toilet seat unit 40 by hand. To manually lower the toilet seat unit 40, the user slowly pushes the toilet seat unit 40 down by hand. To electrically raise or lower the toilet seat unit 40, the user operates the first operating mechanism 21, which will be described later. By operating the first operating mechanism 21, the lifting device 42, which will be described later, is activated, and the toilet seat unit 40 rises or falls.

[0025] As shown in Figure 3, the toilet system R is equipped with various devices. These devices include a lifting device 42, a toilet seat drive device 43, a toilet lid drive device 44, a local washing device 45, a toilet bowl cleaning device 46, a spray device 47, and a control device 49. The lifting device 42, toilet seat drive device 43, toilet lid drive device 44, local washing device 45, toilet bowl cleaning device 46, and spray device 47 are controlled by the control device 49. The control device 49 controls these devices based on the operation information from the operation unit 20 and the detection information from the detection unit 30.

[0026] The control unit 20 is provided for operating various devices. When the user operates the control unit 20, an operation signal is sent to the control device 49. The control device 49 controls the various devices based on the received operation signal. The user can operate the various devices at any time by operating the control unit 20.

[0027] As shown in Figure 1, the control unit 20 comprises a first control unit 21 located away from the toilet unit R and a second control unit 22 provided on the toilet unit R itself. The first control unit 21 is, for example, a remote control mounted on the wall of the toilet room. The first control unit 21 is equipped with multiple switches corresponding to various devices. The switches include a local flush switch, a toilet bowl flush switch, a mist switch, a lift switch, etc. The second control unit 22 is, for example, a flush handle or lever provided on the toilet seat unit 40.

[0028] As shown in Figure 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 who is in front of the toilet bowl 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 who is in front of the toilet bowl body 10 when the toilet lid 12 is in the down position. The lower detection unit detects a user who is in front of the toilet bowl body 10 when the toilet lid 12 is in the upright position. The seating detection unit 32 detects whether or not a user is seated on the toilet seat 11.

[0029] The lifting device 42 supports the casing 41 of the toilet seat unit 40. The lifting device 42 is fixed to the toilet bowl body 10. Based on commands from the control device 49, the lifting device 42 electrically raises and lowers the toilet seat unit 40. As the toilet seat unit 40 rises, the lower surface of the casing 41 is lifted above the rear upper surface of the toilet bowl body 10.

[0030] The toilet seat 11 and toilet lid 12 rotate and move either manually or automatically. In manual mode, the toilet seat 11 and toilet lid 12 rotate and move when pushed by the user's hand. In automatic mode, the toilet seat 11 and toilet lid 12 rotate and move by the operation of the toilet seat drive unit 43 and the toilet lid drive unit 44. The toilet seat drive unit 43 and the toilet lid drive unit 44 are fixed to the casing 41. The toilet seat drive unit 43 electrically rotates the toilet seat 11 based on a command from the control unit 49. The toilet lid drive unit 44 electrically rotates the toilet lid 12 based on a command from the control unit 49. The toilet lid drive unit 44 automatically activates when a user approaches the vicinity of the toilet bowl body 10 before sitting on the toilet seat 11, and rotates the toilet lid 12 from a reclined state to an upright state. The toilet lid drive device 44 automatically activates when the user stands up from the toilet seat 11 and moves away from the toilet bowl body 10, rotating the toilet lid 12 from an upright position to a reclined position.

[0031] The local cleaning device 45 cleans the user's private parts based on commands from the control device 49. The local cleaning device 45 is equipped with a nozzle 45A that discharges water for local cleaning. The user can activate the local cleaning device 45 and clean their private parts at any time by operating the first operating unit 21.

[0032] The toilet flushing device 46 supplies flushing water to the toilet bowl 13 via the discharge port 18, and flushes the toilet bowl 13. The toilet flushing device 46 can be operated either manually or automatically. In manual operation, the toilet flushing device 46 is operated by either the first operation unit 21 or the second operation unit 22. The user can operate the toilet flushing device 46 at any time by operating either the first operation unit 21 or the second operation unit 22. In automatic operation, the toilet flushing device 46 operates based on a command from the control unit 49. The toilet flushing device 46 automatically activates when the user stands up from the toilet seat 11 and flushes the toilet bowl 13.

[0033] The spraying device 47 sprays mist onto a predetermined area of ​​the toilet bowl body 10 and the toilet seat device 40. The mist is a mist-like liquid suspended in the gas. The liquid can be tap water or disinfectant water. The liquid may also be disinfectant water containing hypochlorous acid, a solution containing metal ions such as silver ions or copper ions, a solution containing electrolytic chlorine or ozone, acidic water, alkaline water, etc.

[0034] The spraying device 47 is equipped with a nozzle 47A that sprays mist. The nozzle 47A is positioned below the reclined toilet seat 11. The nozzle 47A is located near the nozzle 45A of the local bidet device 45. The nozzle 47A is attached to the base plate of the local bidet device 45.

[0035] The spraying device 47 sprays mist onto a first predetermined area of ​​at least one of the toilet bowl body 10 and the toilet seat device 40. The first predetermined area is the area to which the spraying device 47 adheres mist under normal conditions, not predetermined conditions. The first predetermined area is one of the first areas. The first area is the area below the toilet lid 12 when the toilet bowl portion 13 is covered by the toilet lid 12. The area below the toilet lid 12 when the toilet bowl portion 13 is covered by the toilet lid 12 is the area below the virtual surface H that extends along the lid portion 12A of the inverted toilet lid 12, as shown in Figure 2. The virtual surface H is a reference surface regardless of whether the toilet lid 12 is in an upright or inverted 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 waste receiving surface 14, the upper and lower surfaces of the inverted toilet seat 11, the lower surface of the inverted toilet lid 12, and the outer surface of the toilet bowl body 10 covered by the toilet lid 12. The first predetermined area includes 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, etc.

[0036] The spraying device 47 may also spray mist into a second and third region in addition to the first predetermined region. The second region is a region where dirt is likely to scatter and adhere. Specifically, the second region is, for example, the rim 15 at the rear of the toilet bowl 13. The third region is a region where the washing water does not flow easily. Specifically, the third region is, for example, the region above the discharge port 18 on the inner surface 17 of the rim 15, or the region on the opposite side of the discharge port 18 on the inner surface 17 of the rim 15.

[0037] The spraying device 47 may also be equipped with a blower. In this case, the blower can generate an airflow inside the toilet bowl 13, causing the mist to rise. This allows the spraying device 47 to blow the mist onto the toilet seat 11 and toilet lid 12 of the toilet bowl body 10.

[0038] The spraying device 47 can be operated either manually or automatically. In manual operation, the spraying device 47 is operated by the operation of the first operation unit 21. The user can operate the spraying device 47 and spray mist at any time by operating the first operation unit 21. In automatic operation, the spraying device 47 is operated based on a command from the control device 49. The control device 49 causes the spraying device 47 to spray mist at a preset timing. Specifically, the spraying device 47 sprays 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 use is called periodic mist. Manual mist, pre-mist, after-mist, and periodic mist are each sprayed for a predetermined time T. The predetermined time T may be set appropriately for each mist. The predetermined time T may differ for each mist.

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

[0040] Based on the detection information from the human body detection unit 31, the control device 49 determines that the state has changed from one where no user is detected to one where a user is detected, and then causes the spraying device 47 to spray pre-mist. The area where the pre-mist is sprayed is the area excluding the top surface of the toilet seat 11.

[0041] Based on the detection information from the human body detection unit 31, the control device 49 determines that the state has changed from detecting a user to not detecting a user, and then causes the spraying device 47 to spray after-mist. The spraying area of ​​the after-mist may extend over a wide area 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 spraying device 47 to spray periodic mist at predetermined timings. The timing of the periodic mist may be, for example, predetermined days of the week or times, or it may be after a predetermined time has elapsed since the end of the last mist, whether manual mist, pre-mist, after-mist, or periodic mist. The spraying area of ​​the periodic mist may be the second and third areas. This suppresses drying in the second and third areas and prevents the adhesion of limescale and dirt.

[0043] The control device 49 sets the spraying device 47 to either a first state or a second state under predetermined conditions. In the first state, the spraying device 47 is stopped. The first state includes a state in which the operating spraying device 47 has stopped immediately, a state in which the operating spraying device 47 has stopped in a time shorter than a predetermined time T, and a state in which 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 waste receiving surface 14 of the toilet bowl 13, or an area close to the water surface of the toilet bowl 13. Means for changing the mist spraying area from a first predetermined area to a second predetermined area may include, for example, reducing the amount of liquid to be sprayed, changing the direction of the airflow of the blower, reducing the force of the spray, changing the particle size of the mist, changing the direction of mist ejection from the nozzle 47A, or providing nozzles 47A at the top and bottom of the toilet device R and ejecting only from the lower nozzle 47A.

[0044] The predetermined conditions are when a person is approaching the vicinity of the toilet bowl 10. Specifically, the predetermined conditions are as follows: Condition 1, Condition 2, Condition 3, Condition 4, Condition 5, Condition 6, and Condition 7. Condition 1 is when the user approaches the vicinity of the toilet bowl 10 before sitting on the toilet seat 11. Condition 2 is when the user is in the vicinity of the toilet bowl 10 with the toilet lid 12 in the upright position. 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 moves from the reclined position to the upright position. Condition 5 is when the control unit 20 is operated. Condition 6 is when the operation of the toilet flushing device 46 is instructed. Condition 7 is when the raising of the toilet seat device 40 is instructed.

[0045] The control patterns under each condition will be explained. (1) Condition 1: When the user approaches the vicinity of the toilet bowl 10 before sitting on the toilet seat 11 Condition 1 is that during the spraying of manual mist, after-mist, or periodic mist, a user may approach the vicinity of the toilet bowl 10 before sitting on the toilet seat 11. In this case, the control pattern has a first control pattern, a second control pattern, and a third control pattern, as shown in Figure 4.

[0046] (1-1) First control pattern Even if the control device 49 determines, based on the detection information from the human body detection unit 31, that the state has changed from one where no user is detected to one where a user is detected, it does not activate the toilet lid drive device 44. The control device 49 causes the spraying device 47 to spray manual mist, after-mist, and periodic mist until a predetermined time T has ended. The control device 49 also does not activate the toilet lid drive device 44 after the spraying of manual mist, after-mist, and periodic mist has ended. In the first control pattern, even if a user approaches the toilet bowl 10 before sitting down, the toilet lid 12 does not become upright. With this configuration, the toilet lid drive device 44 stops while mist is being sprayed. This prevents the user from sitting on the toilet seat 11 while mist is being sprayed, making it less likely for mist to come into contact with a person.

[0047] (1-2) Second control pattern Based on the detection information from the human body detection unit 31, the control device 49 determines that the state has changed from one in which no user is detected to one in which a user is detected. Upon this determination, it activates the toilet lid drive device 44 and sets the spray device 47 to either the first or second state. In the second control pattern, the spraying time of the manual mist, after-mist, and periodic mist becomes shorter than a predetermined time T, or the area in which the manual mist, after-mist, and periodic mist are sprayed changes from the first predetermined area to the second predetermined area. Therefore, when a user approaches the vicinity of the toilet bowl body 10 before sitting on the toilet seat 11, it becomes less likely for the person to be sprayed with mist.

[0048] (1-3) Third control pattern Even if the control device 49 determines, based on the detection information from the human body detection unit 31, that the state has changed from one where no user is detected to one where a user is detected, it does not activate the toilet lid drive device 44, but instead causes the spray device 47 to spray manual mist, after-mist, and periodic mist until the predetermined time T is over. The control device 49 activates the toilet lid drive device 44 after the spraying of manual mist, after-mist, and periodic mist has finished. In the third control pattern, mist spraying is performed until the predetermined time T is over. When a user approaches the toilet bowl 10 before sitting down, the toilet lid 12 stands upright after a delay equal to the mist spraying time.

[0049] (2) Condition 2: When the toilet lid 12 is in the upright position and the user is near the toilet bowl 10 Condition 2 describes the control system when the next user approaches the vicinity of the toilet bowl body 10 before the toilet lid 12 is lowered while the regular mist is being sprayed.

[0050] During periodic mist spraying, the control device 49 determines, based on the detection information from the lower detection unit of the human body detection unit 31, that the state has changed from one in which a user was not detected to one in which a user is detected, and sets the spraying device 47 to either the first state or the second state.

[0051] If the control device 49 detects that a user who has stood up from the toilet seat 11 is located near the toilet bowl 10 while manual mist and pre-mist are being sprayed, it may cause the spraying device 47 to spray until the predetermined time T is finished.

[0052] (3) Condition 3: When the user sits on the toilet seat 11 When the control device 49 detects that a user has sat on the toilet seat 11 during the spraying of manual mist, after-mist, or periodic mist, it sets the spraying device 47 to either the first state or the second state.

[0053] With this configuration, when the user sits on the toilet seat 11, the spraying device 47 either stops or sprays mist onto a second predetermined area of ​​the toilet bowl body 10. Therefore, it is possible to make it less likely for the mist to come into contact with the user's buttocks, thus improving usability.

[0054] If the control device 49 detects that a user has sat on the toilet seat 11 while the pre-mist is being sprayed, it may cause the spraying device 47 to continue spraying the pre-mist until the predetermined time T is finished.

[0055] (4) Condition 4: When either the toilet seat 11 or the toilet lid 12 changes from a reclined position to an upright position. Condition 4 includes cases where the plant is manually brought to an upright position and cases where it is brought to an upright position automatically. The case where it is brought to an upright position automatically is included in Conditions 1 and 5. Condition 4 will now explain the case where the plant is manually brought from a collapsed position to an upright position.

[0056] When the control device 49 detects that either the toilet seat 11 or the toilet lid 12 has been manually raised during the spraying of manual mist, after-mist, or periodic mist, it sets the spraying device 47 to either the first state or the second state.

[0057] With this configuration, when either the toilet seat 11 or the toilet lid 12 is manually raised from a reclined position to an upright position, the spraying device 47 either stops or sprays mist onto a second predetermined area of ​​the toilet bowl body 10. Therefore, it is less likely that mist will get on the user's hands, thus improving usability.

[0058] If the control device 49 detects that either the toilet seat 11 or the toilet lid 12 has been manually raised while the pre-mist is being sprayed, it may cause the spraying device 47 to spray the pre-mist until the predetermined time T is completed.

[0059] (5) Condition 5: When the operating unit 20 is operated When the control unit 20 is operated by a user who is not seated, this falls under condition 1. Operation of the toilet flushing device 46 falls under condition 6. Operation of the lifting device 42 falls under condition 7. Condition 5 describes the case when the local bidet device 45 is operated by a seated user.

[0060] When the control device 49 receives an operation signal for the local cleaning switch on the first operation unit 21 during manual mist, after-mist, or periodic mist spraying, it sets the spraying device 47 to either the first or second state. This configuration makes it less likely for the user operating the operation unit 20 to be sprayed with mist.

[0061] If the control device 49 receives an operation signal for the local cleaning switch of the first operation unit 21 while the pre-mist is being sprayed, it may cause the spraying device 47 to spray until the predetermined time T is finished.

[0062] (6) Condition 6: When the toilet flushing device 46 is instructed to be activated The toilet flushing device 46 can be operated manually or automatically. Manual operation is performed by operating the control unit 20. Automatic operation is performed when the control device 49 determines, based on the detection information from the seating detection unit 32, that the user has stood up from the toilet seat 11.

[0063] Condition 6 describes the case where the toilet flushing device 46 is instructed to operate during manual mist, pre-mist, after-mist, or periodic mist spraying. In this case, the control patterns include a first control pattern, a second control pattern, a third control pattern, and a fourth control pattern, as shown in Figure 5.

[0064] (6-1) First control pattern Even if the control device 49 receives an instruction to operate the toilet flushing device 46 while manual mist, pre-mist, after-mist, or periodic mist is being sprayed, it does not operate the toilet flushing device 46. The control device 49 continues to spray manual mist, pre-mist, after-mist, and periodic mist through the spraying device 47 until the end of the predetermined time T. The control device 49 operates the toilet flushing device 46 only after the spraying of manual mist, pre-mist, after-mist, and periodic mist has ended. In the first control pattern, the toilet flushing device 46 operates with a delay of the mist spraying time compared to the timing of the instruction to operate the toilet flushing device 46, and the toilet bowl 13 is flushed.

[0065] (6-2) Second control pattern When the control device 49 receives an instruction to operate the toilet flushing device 46 while manual mist, pre-mist, after-mist, or periodic mist is being sprayed, it activates the toilet flushing device 46 and sets the spraying device 47 to either the first or second state. In the second control pattern, the spraying time for manual mist, pre-mist, after-mist, and periodic mist becomes shorter than a predetermined time T, or the mist spraying area becomes a second predetermined area. When an instruction to operate the toilet flushing device 46 is received, the toilet flushing device 46 is activated and the toilet bowl 13 is cleaned. With this configuration, it is possible to make it less likely for mist to come into contact with a user standing near the toilet bowl 10.

[0066] (6-3) Third control pattern When the control device 49 receives an instruction to operate the toilet flushing device 46 while the manual mist, pre-mist, after-mist, or periodic mist is being sprayed, it operates the toilet flushing device 46 while the spraying device 47 continues to spray the manual mist, pre-mist, after-mist, or periodic mist. In the third control pattern, the mist is sprayed and the toilet bowl 13 is flushed simultaneously. With this configuration, the toilet bowl 13 can be flushed while the mist is being sprayed, which improves usability.

[0067] (6-4) Fourth control pattern Even if the control device 49 receives an instruction to operate the toilet flushing device 46 while manual mist, pre-mist, after-mist, or periodic mist is being sprayed, it will not operate the toilet flushing device 46. The control device 49 will have the spraying device 47 spray manual mist, pre-mist, after-mist, or periodic mist until a predetermined time T has ended. The control device 49 will not operate the toilet flushing device 46 even after the spraying of manual mist, pre-mist, after-mist, or periodic mist by the spraying device 47 has ended. In the fourth control pattern, mist spraying is performed until the predetermined time T has ended. Even if there is an instruction to operate the toilet flushing device 46, the toilet bowl 13 will not be flushed.

[0068] (7) Condition 7: When the toilet seat device 40 is instructed to rise Condition 7 has two cases: the first case in which the toilet seat device 40 is instructed to rise while mist is being sprayed, and the second case in which the timing for mist spraying occurs when the toilet seat device 40 is raised.

[0069] In the first case, when the control device 49 receives an operation signal from the first operation unit 21 to raise the toilet seat device 40 while spraying manual mist, pre-mist, after-mist, or periodic 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 is completed. While mist is being sprayed, the toilet seat device 40 will not rise even if the first operation unit 21 is operated to raise.

[0070] In the second case, the control device 49 cancels the mist spraying instruction when the toilet seat device 40 is raised and it is time for mist spraying. This prevents the mist from hitting the person who is raising the toilet seat device 40 to clean.

[0071] The embodiment configured as described above provides the following effects. The toilet device R includes a toilet bowl body 10, a toilet seat device 40, a spray device 47, and a control device 49. The toilet bowl body 10 has a toilet bowl portion 13. The toilet seat device 40 is positioned on the upper surface of the toilet bowl body 10. The spray device 47 sprays mist onto a first predetermined area of ​​at least one of the toilet bowl body 10 and the toilet seat device 40. The control device 49 controls the spray device 47 to either be stopped or to spray mist onto a second predetermined area whose upper end position is lower than the first predetermined area, under predetermined conditions. With this configuration, under predetermined conditions, the spray device 47 is either stopped or sprays mist onto a second predetermined area lower than the first predetermined area. Therefore, under predetermined conditions, it is less likely that mist will come into contact with a person, thus improving usability.

[0072] The toilet seat device 40 has a toilet lid 12 that covers the upper part of the toilet bowl 13. The first predetermined area is any area below the toilet lid 12 when the toilet bowl 13 is covered by the toilet lid 12. With this configuration, the mist is sprayed onto any area below the toilet lid 12 when the toilet bowl 13 is covered, making it less likely for the mist to come into contact with a person.

[0073] The predetermined condition is when a person approaches the vicinity of the toilet bowl 10. With this configuration, when a user approaches the vicinity of the toilet bowl 10, the spraying device 47 either stops or sprays mist onto a second predetermined area of ​​the toilet bowl 10. Therefore, it is possible to make it less likely for mist to come into contact with a person under the predetermined condition, thus improving usability.

[0074] The toilet device R has a toilet seat 11. The predetermined condition is when a user sits on the toilet seat 11. With this configuration, when a user sits on the toilet seat 11, the spray device 47 either stops or sprays mist onto a second predetermined area of ​​the toilet bowl body 10. Therefore, under the predetermined condition, it is possible to make it less likely for mist to come into contact with a person, thus improving usability.

[0075] The toilet seat 11 and toilet lid 12 rotate between a reclined state, aligned with the upper surface 16 of the toilet bowl 13, and an upright state, standing above the upper surface 16 of the toilet bowl 13. The predetermined condition is when at least one of the toilet seat 11 and toilet lid 12 rotates from the reclined state to the upright state. With this configuration, when at least one of the toilet seat 11 and toilet lid 12 moves from the reclined state to the upright state, the spraying device 47 stops or sprays mist onto a second predetermined area of ​​the toilet bowl body 10. Therefore, under the predetermined condition, it is less likely that mist will come into contact with a person, thus improving usability.

[0076] The toilet device R has an operating unit 20 for operating various devices. The predetermined condition is when the operating unit 20 is operated. With this configuration, when the operating unit 20 is operated, the spray device 47 stops or sprays mist onto a second predetermined area of ​​the toilet bowl body 10. Therefore, under the predetermined condition, it is possible to make it less likely for mist to come into contact with people, thus improving usability.

[0077] The toilet unit R has a toilet bowl cleaning device 46 that cleans the toilet bowl 13. The predetermined condition is when the operation of the toilet bowl cleaning device 46 is instructed.
