The flush tank is covered by the casing 41.

[0009] In the following description, the upper side of each component when the toilet device R is installed in a toilet room will be referred to as the upper side, the lower side as the lower side, and the front side as viewed from a person sitting in a normal position on the toilet device R as the front side, the rear side as the rear side, the left side as the left side, and the right side as the right side. In Fig. 1, the positive side of the Z axis is the front side, the negative side of the Z axis is the rear side, the positive side of the Y axis is the upper side, the negative side of the Y axis is the lower side, the positive side of the X axis is the left side, and the negative side of the X axis is the right side.

[0010] The toilet seat 11 and toilet lid 12 each rotate between a laid-down state in which they are aligned along the top surface 16 of the toilet body 10, and an upright state in which they stand above the top surface of the toilet body 10. The toilet lid 12 has a lid portion 12A and a peripheral portion 12B. When the toilet lid 12 is in the laid-down state, the lid portion 12A covers the top surface of the toilet seat 11, and the peripheral portion 12B covers the outer periphery of the toilet seat 11 (see Figure 2).

[0011] As shown in Figure 2, the toilet body 10 has a toilet bowl 13. The toilet bowl 13 has a waste receiving surface 14 that receives waste. Water is stored in the toilet bowl 13. The upper side of the toilet bowl 13 is covered by a toilet lid 12 in a lying down position.

[0012] The upper edge of the toilet bowl 13 is the rim portion 15. The rim portion 15 is annular in plan view. 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 underside of the toilet seat 11 in the laid-down 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 an angle closer to vertical than the waste receiving surface 14.

[0013] The rim portion 15 is provided with an outlet 18 for discharging flushing water. The outlet 18 is located at the rear side of the toilet bowl 13. The flushing water discharged from the outlet 18 flows along the inner surface 17 of the rim portion 15 and swirls around the toilet bowl 13.

[0014] The toilet seat device 40 is disposed on the upper rear surface of the toilet body 10, as shown in FIG. 2. The toilet seat device 40 is raised from or lowered to the upper surface of the toilet body 10 either manually or electrically. When manually raising the toilet seat device 40, the user presses and operates a locking portion 23 (see FIG. 1) provided on the toilet seat device 40 to release the lock, and lifts the toilet seat device 40 with their hands. When manually lowering the toilet seat device 40, the user slowly presses down the toilet seat device 40 with their hands. When electrically raising and lowering the toilet seat device 40, the user operates a first operating unit 21, which will be described later. By operating the first operating unit 21, a lifting and lowering device 42, which will be described later, is activated, and the toilet seat device 40 is raised and lowered.

[0015] The toilet apparatus R is equipped with various devices, as shown in Fig. 3. The various devices include a lifting device 42, a toilet seat drive device 43, a toilet lid drive device 44, a private parts cleansing device 45, a toilet bowl flushing device 46, a spray device 47, and a control device 49. The lifting device 42, the toilet seat drive device 43, the toilet lid drive device 44, the private parts cleansing device 45, the toilet bowl flushing device 46, and the spray device 47 are controlled by the control device 49. The control device 49 controls these devices based on operation information from the operation unit 20 and detection information from the detection unit 30.

[0016] The operation unit 20 is provided to operate various devices. When a user operates the operation unit 20, an operation signal is sent to the control device 49. The control device 49 controls the various devices based on the operation signal sent. By operating the operation unit 20, the user can operate the various devices at any timing.

[0017] As shown in FIG. 1, the operation unit 20 includes a first operation unit 21 located away from the toilet device R, and a second operation unit 22 provided on the toilet device R itself. The first operation unit 21 is, for example, a remote control attached to the wall of the toilet room. The first operation unit 21 includes a number of switches corresponding to various devices. The switches include a private parts cleansing switch, a toilet bowl flushing switch, a mist switch, a lifting switch, etc. The second operation unit 22 is, for example, a flushing handle or lever provided on the toilet seat device 40.

[0018] As shown in Figure 3, the detection unit 30 has 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 has 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 laid-down 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 whether a user is seated on the toilet seat 11.

[0019] The lifting device 42 supports a 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 commands from the control device 49. When the toilet seat device 40 rises, the lower surface of the casing 41 is raised above the upper rear surface of the toilet body 10.

[0020] The toilet seat 11 and toilet lid 12 rotate either manually or automatically. In the manual case, the toilet seat 11 and toilet lid 12 are rotated by being pushed by the user's hand. In the automatic case, the toilet seat 11 and toilet lid 12 rotate by the operation of the toilet seat drive device 43 and the toilet lid drive device 44. The toilet seat drive device 43 and the toilet lid drive device 44 are fixed to the casing 41. The toilet seat drive device 43 rotates the toilet seat 11 electrically based on a command from the control device 49. The toilet lid drive device 44 rotates the toilet lid 12 electrically based on a command from the control device 49. The toilet lid drive device 44 automatically operates 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 lying down position to an upright position. When a user stands up from the toilet seat 11 and leaves the toilet body 10, the toilet cover drive device 44 automatically operates to rotate the toilet cover 12 from an upright position to a laid-down position.

[0021] The local area washing device 45 washes the local area of ​​the user based on commands from the control device 49. The local area washing device 45 is equipped with a nozzle 45A that ejects water for washing the local area. The user can operate the local area washing device 45 at any timing to wash the local area by operating the first operating part 21.

[0022] The toilet flushing device 46 supplies flushing water to the toilet bowl 13 via the outlet 18, flushing the toilet bowl 13. The toilet flushing device 46 is operated either manually or automatically. When operated manually, the toilet flushing device 46 is operated by operating either the first operating unit 21 or the second operating unit 22. The user can operate the toilet flushing device 46 at any timing by operating either the first operating unit 21 or the second operating unit 22. When operated automatically, the toilet flushing device 46 is operated based on a command from the control device 49. The toilet flushing device 46 automatically operates when the user stands up from the toilet seat 11, and flushes the toilet bowl 13.

[0023] The spray 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 gas. The liquid may be 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 or copper ions, a solution containing electrolytic chlorine or ozone, acidic water, alkaline water, or the like.

[0024] The spray device 47 is equipped with a nozzle 47A that sprays mist. The nozzle 47A is disposed below the toilet seat 11 in the reclined position. The nozzle 47A is provided near the nozzle 45A of the local cleansing device 45. The nozzle 47A is attached to the base plate of the local cleansing device 45.

[0025] The spray device 47 sprays mist onto a first predetermined area of ​​at least one of the toilet body 10 and the toilet seat device 40. The first predetermined area is an area to which the mist is applied by the spray device 47 under normal conditions other than the specified conditions. The first predetermined area is any one of the first areas. The first area is an area below the toilet lid 12 when the toilet bowl 13 is covered by the toilet lid 12. The area below the toilet lid 12 when the toilet bowl 13 is covered by the toilet lid 12 is an area below an imaginary plane H that spreads along the lid portion 12A of the toilet lid 12 in a lying down state, as shown in FIG. 2. The imaginary plane H is a reference plane that does not matter whether the toilet lid 12 is in an upright or lying down state. The area below imaginary plane H specifically includes upper surface 16 of rim portion 15, inner surface 17 of rim portion 15, waste receiving surface 14, upper and lower surfaces of toilet seat 11 in the laid-down state, the lower surface of toilet lid 12 in the laid-down state, the outer surface of toilet body 10 covered by toilet lid 12, etc. The first predetermined area includes the entire area of ​​toilet bowl 13, toilet bowl 13 and toilet seat 11, toilet bowl 13, toilet seat 11 and toilet lid 12, etc.

[0026] The spray device 47 may be configured to spray mist to a second area and a third area in addition to the first predetermined area. The second area is an area where waste 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 13. The third area is an area where flushing water is unlikely to flow. Specifically, the third area is, for example, an area above the outlet 18 on the inner surface 17 of the rim portion 15, or an area on the opposite side of the outlet 18 on the inner surface 17 of the rim portion 15.

[0027] The spray device 47 may be equipped with an air blower. In this case, the air blower can generate an air current inside the toilet bowl 13, causing the mist to rise. This enables the spray device 47 to blow the mist onto the toilet seat 11 and toilet lid 12 of the toilet body 10.

[0028] The spray device 47 is operated either manually or automatically. In the case of manual operation, the spray device 47 is operated by operating the first operating unit 21. The user can operate the spray device 47 at any timing and spray mist by operating the first operating unit 21. In the case of automatic operation, the spray device 47 is operated based on a command from the control device 49. The control device 49 causes the spray device 47 to spray mist at a preset timing. Specifically, the spray 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 whether the toilet device R 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 set appropriately for each mist. The predetermined time T may be different for each mist.

[0029] A few specific examples of control patterns of spray device 47 by control device 49 will be described below. When control device 49 receives an operation signal from the mist switch of first operation unit 21, it causes spray device 47 to spray manual mist.

[0030] When the control device 49 determines that a state in which a user is detected has changed from a state in which a user is not detected based on the detection information of the human body detection unit 31, it causes the spray device 47 to spray pre-mist. The area in which the pre-mist is sprayed is, for example, an area excluding the upper surface of the toilet seat 11.

[0031] When the control device 49 determines that the state has changed from detecting a user to not detecting a user based on the detection information from the human body detection unit 31, it causes the spray device 47 to spray the after-mist. The after-mist spray area may cover a wide range of the toilet device R, and may include the upper surface of the toilet seat 11, for example.

[0032] The control device 49 causes the spray device 47 to spray regular mist at a predetermined timing. The timing of regular mist may be, for example, a predetermined day or time, or a predetermined time after the end of the last mist of the manual mist, pre-mist, after-mist, or regular mist. The spray area of ​​regular mist may be the second area and the third area. This makes it possible to suppress drying of the second area and the third area and prevent water stains and dirt from adhering.

[0033] The control device 49 puts the spray device 47 into either a first state or a second state under a predetermined condition. In the first state, the spray device 47 stops. The first state includes a state in which the operating spray device 47 stops immediately, a state in which the operating spray device 47 stops for a time shorter than the predetermined time T, and a state in which the stopped spray device 47 continues to stop. In the second state, the mist is sprayed to 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 spray area from the first specified area to the second specified area may be, for example, reducing the amount of liquid sprayed, changing the direction of the airflow from the blower, eliminating the force of the spray, changing the particle size of the mist, changing the direction in which the mist is sprayed from nozzle 47A, providing nozzles 47A at the top and bottom of toilet device R and spraying mist only from the lower nozzle 47A, etc.

[0034] The specified condition is when a person approaches the vicinity of the toilet body 10. The specified conditions are specifically as follows: Condition 1, Condition 2, Condition 3, Condition 4, Condition 5, Condition 6, and Condition 7. Condition 1 is when a user approaches the vicinity of the toilet body 10 before sitting on the toilet seat 11. Condition 2 is when a user is present in the vicinity of the toilet body 10 with the toilet lid 12 in an upright position. Condition 3 is when a user sits on the toilet seat 11. Condition 4 is when either the toilet seat 11 or the toilet lid 12 changes from a reclined position to an upright position. Condition 5 is when the operating unit 20 is operated. Condition 6 is when an instruction is given to operate the toilet flushing device 46. Condition 7 is when an instruction is given to raise the toilet seat device 40.

[0035] The control pattern for each condition will be described. (1) Condition 1: When a user approaches the vicinity of the toilet body 10 before sitting on the toilet seat 11 Condition 1 is that while any of manual mist, after-mist, and regular mist is being sprayed, a user before sitting on the toilet seat 11 may approach the vicinity of the toilet body 10. The control patterns in this case include a first control pattern, a second control pattern, and a third control pattern, as shown in FIG.

[0036] (1-1) First control pattern The control device 49 does not operate the toilet lid drive device 44 even if it determines that the state has changed from not detecting a user to detecting a user based on the detection information of the human body detection unit 31. The control device 49 causes the spray device 47 to spray the manual mist, after-mist, and regular mist until the end of the specified time T. The control device 49 does not operate the toilet lid drive device 44 even after the spraying of the manual mist, after-mist, and regular mist has ended. In the first control pattern, even if a user approaches the toilet body 10 before sitting down, the toilet lid 12 does not rise. According to this configuration, the toilet lid drive device 44 stops while the mist is being sprayed. This prevents the user from sitting on the toilet seat 11 while the mist is being sprayed, making it difficult for the mist to splash on the person.

[0037] (1-2) Second control pattern When the control device 49 determines that a user has been detected in a state where a user is not being detected, based on the detection information from the human body detection unit 31, it activates the toilet lid drive device 44 and sets the spray device 47 to either the first state or the second state. In the second control pattern, the spray time of the manual mist, after mist, and regular mist becomes shorter than the predetermined time T, or the area sprayed with the manual mist, after mist, and regular mist changes from the first predetermined area to the second predetermined area. Therefore, when a user approaches the vicinity of the toilet body 10 before sitting on the toilet seat 11, it is possible to prevent the mist from splashing on the person.

[0038] (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 a state has changed from not detecting a user to detecting a user, it does not operate the toilet lid drive device 44, but causes the spray device 47 to spray manual mist, after-mist, and regular mist until the end of the specified time T. After spraying of the manual mist, after-mist, and regular mist has finished, the control device 49 operates the toilet lid drive device 44. In the third control pattern, mist spraying continues until the end of the specified time T. When a user approaches the toilet body 10 before sitting down, the toilet lid 12 becomes upright with a delay of the time it takes for the mist to be sprayed.

[0039] (2) Condition 2: When the toilet lid 12 is in the upright position and the user is present near the toilet body 10 As condition 2, a control will be described for the case where the next user approaches the vicinity of the toilet body 10 before the toilet lid 12 is in the down position while the regular mist is being sprayed.

[0040] When the control device 49 determines, during spraying of regular mist, based on detection information from the lower detection section of the human body detection unit 31, that a state has changed from not detecting a user to a state where a user is detected, it sets the spray device 47 to either the first state or the second state.

[0041] 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 while manual mist and pre-mist are being sprayed, it may cause the spray device 47 to spray until the end of a predetermined time T.

[0042] (3) Condition 3: When the user sits on the toilet seat 11 When the control device 49 determines that a user has sat on the toilet seat 11 while either the manual mist, after-mist or regular mist is being sprayed, it sets the spray device 47 to either the first state or the second state.

[0043] According to this configuration, when the user sits on the toilet seat 11, the spray device 47 stops or sprays mist onto a second predetermined area of ​​the toilet body 10. This makes it difficult for the mist to get on the user's buttocks, improving usability.

[0044] When the control device 49 determines that a user has sat on the toilet seat 11 while the pre-mist is being sprayed, the control device 49 may cause the spray device 47 to spray the pre-mist until the predetermined time T has elapsed.

[0045] (4) Condition 4: When either the toilet seat 11 or the toilet lid 12 changes from a reclined state to an upright state. Condition 4 includes a case where the standing state is changed manually and a case where the standing state is changed automatically. The case where the standing state is changed automatically is included in condition 1 and condition 5. Regarding condition 4, a case where the standing state is changed manually from the lying state will be described.

[0046] When the control device 49 determines that either the toilet seat 11 or the toilet lid 12 has been manually raised while spraying either the manual mist, after-mist, or regular mist, it sets the spray device 47 to either the first state or the second state.

[0047] According to this configuration, when either the toilet seat 11 or the toilet lid 12 is manually changed from a reclined state to an upright state, the spray device 47 stops or sprays mist onto a second predetermined area of ​​the toilet body 10. This makes it difficult for the mist to get on the user's hands, improving usability.

[0048] If the control device 49 determines that either the toilet seat 11 or the toilet lid 12 has been manually raised while spraying pre-mist, it may cause the spray device 47 to spray pre-mist until the end of a predetermined time T.

[0049] (5) Condition 5: When the operation unit 20 is operated When the operating unit 20 is operated by a user who is not seated, this falls under condition 1. The operation of the toilet flushing device 46 falls under condition 6. The operation of the lifting device 42 falls under condition 7. Condition 5 describes the case where the private parts cleaning device 45 is operated by a user who is seated.

[0050] When the control device 49 receives an operation signal from the local cleaning switch of the first operating unit 21 while the manual mist, after-mist, or regular mist is being sprayed, it sets the spray device 47 to either the first state or the second state. With this configuration, it is possible to prevent the mist from hitting the user operating the operating unit 20.

[0051] When the control device 49 receives an operation signal of the local cleaning switch of the first operation unit 21 during spraying of the pre-mist, the control device 49 may cause the spray device 47 to spray until the predetermined time T has elapsed.

[0052] (6) Condition 6: When an instruction to operate the toilet flushing device 46 is given The operation of the toilet flushing device 46 can be commanded either manually or automatically. Manual commands are issued by operating the operation unit 20. Automatic commands are issued when the control device 49 determines that the user has stood up from the toilet seat 11 based on detection information from the seating detection unit 32.

[0053] Condition 6 describes a case where operation of the toilet flushing device 46 is instructed while manual mist, pre-mist, after-mist, or regular mist is being sprayed. The control patterns in this case include a first control pattern, a second control pattern, a third control pattern, and a fourth control pattern, as shown in FIG.

[0054] (6-1) First control pattern Even if control device 49 receives an instruction to operate toilet flushing device 46 while spraying manual mist, pre-mist, after-mist, or regular mist, it does not operate toilet flushing device 46. Control device 49 causes spray device 47 to continue spraying manual mist, pre-mist, after-mist, and regular mist until the end of specified time T. Control device 49 operates toilet flushing device 46 after stopping spraying of manual mist, pre-mist, after-mist, and regular mist. In the first control pattern, toilet flushing device 46 operates with a delay of the mist spraying time from the timing when an instruction to operate toilet flushing device 46 was received, and toilet bowl 13 is flushed.

[0055] (6-2) Second control pattern When control device 49 receives an instruction to operate toilet flushing device 46 while spraying manual mist, pre-mist, after-mist, or regular mist, it operates toilet flushing device 46 and sets spray device 47 to either the first state or the second state. In the second control pattern, the spray time of manual mist, pre-mist, after-mist, or regular mist is shorter than predetermined time T, or the mist spray area becomes a second predetermined area. When an instruction to operate toilet flushing device 46 is received, toilet flushing device 46 operates and flushes toilet bowl 13. With this configuration, it is possible to prevent mist from splashing on a user standing near toilet body 10.

[0056] (6-3) Third control pattern When control device 49 receives a command to operate toilet flushing device 46 while spraying manual mist, pre-mist, after-mist, or regular mist, it operates toilet flushing device 46 while continuing to spray manual mist, pre-mist, after-mist, or regular mist from spray device 47. In the third control pattern, mist is sprayed and the toilet bowl 13 is flushed simultaneously. With this configuration, the toilet bowl 13 can be flushed while mist is being sprayed, making it easier to use.

[0057] (6-4) Fourth control pattern The control device 49 does not operate the toilet flushing device 46, even if it receives an instruction to operate the toilet flushing device 46 while spraying the manual mist, pre-mist, after-mist, or regular mist. The control device 49 causes the spray device 47 to spray the manual mist, pre-mist, after-mist, or regular mist until the end of the specified time T. The control device 49 does not operate the toilet flushing device 46, even after it has caused the spray device 47 to stop spraying the manual mist, pre-mist, after-mist, or regular mist. In the fourth control pattern, the mist is sprayed until the end of the specified time T. Even if an instruction to operate the toilet flushing device 46 is given, the toilet bowl 13 is not flushed.

[0058] (7) Condition 7: When an instruction to raise the toilet seat device 40 is given Condition 7 includes a first case in which an instruction to raise the toilet seat device 40 is issued while mist is being sprayed, and a second case in which the timing for mist spraying occurs when the toilet seat device 40 is raised.

[0059] In the first case, when the control device 49 receives an operation signal for operating the first operating unit 21 to raise the toilet seat device 40 while spraying any of the manual mist, pre-mist, after-mist, or regular mist, it cancels the command to raise the toilet seat device 40 and causes the sprayer 47 to spray until the end of the specified time T. While mist is being sprayed, the toilet seat device 40 will not rise even if the first operating unit 21 is operated to raise the toilet seat device 40.

[0060] In the second case, when the timing for mist spraying arrives while the toilet seat device 40 is raised, the control device 49 cancels the instruction to spray mist. This makes it possible to prevent the mist from reaching a person who is cleaning by raising the toilet seat device 40.

[0061] According to the embodiment configured as above, the following effects are achieved. The toilet device R has a toilet body 10, a toilet seat device 40, a spray device 47, and a control device 49. The toilet body 10 has a toilet bowl 13. The toilet seat device 40 is disposed on the upper surface of the toilet body 10. The spray device 47 sprays mist to a first predetermined area of ​​at least one of the toilet body 10 and the toilet seat device 40. The control device 49 controls the spray device 47 to either a state in which the spray device 47 is stopped or a state in which the spray device 47 sprays mist to a second predetermined area whose upper end position is lower than the first predetermined area under a predetermined condition. According to this configuration, under a predetermined condition, the spray device 47 stops or sprays mist to a second predetermined area whose upper end position is lower than the first predetermined area.
