And the toilet device 1 includes a toilet seat 24, a toilet seat opening / closing detection unit 25 that detects the opening and closing of the toilet seat 24, a toilet seat driving unit 26 that opens and closes the toilet seat 24, a toilet seat operation unit 27 that receives an opening / closing instruction for the toilet seat driving unit 26, and further includes a seating detection unit 28. Next, each member constituting the toilet device 1 will be described in detail.

[0014] The toilet device 1 is a wall-mounted Western-style toilet device fixed to the floor, wall, etc. in the toilet space. The toilet body 10 of this toilet device 1 includes a bowl 12 that opens upward, a skirt portion 11 that surrounds the periphery of the bowl 12, and a toilet seat 24 and a toilet lid 20 that are rotatable and can be tilted with respect to the opening surface of the bowl 12 above the bowl 12.

[0015] In the internal space of the skirt portion 11, a toilet cleaning unit 13 is arranged that discharges the sewage in the bowl 12 and supplies cleaning water into the bowl 12 from a water supply port 14 to clean the inside of the bowl 12. This toilet cleaning unit 13 has a water supply mechanism and a drainage mechanism.

[0016] The water supply mechanism includes a water supply port 14, a cleaning water supply path 15 that supplies the cleaning water supplied from a water supply pipe (not shown) into the bowl 12 through the water supply port 14, and a water supply valve 16 arranged in the middle of the cleaning water supply path 15 that supplies or shuts off the water supply to the bowl 12.

[0017] The drainage mechanism shown in Fig. 2(a) has a trap 17 which is a bent cylindrical body connected so as to extend rearward from the bottom of the bowl 12, and this trap 17 further extends downward and is connected to a drain port 18. As this type of drainage mechanism, there are a siphon type, a siphon jet type, a siphon vortex type, etc., and it is a mechanism in which a drainage state of draining the accumulated water together with the dirt in the bowl 12 by siphon action or a water sealing state of accumulating the accumulated water in the bowl 12 is formed.

[0018] Also, as the drainage mechanism, a structure having a movable trap 17A as shown in Fig. 2(b) may be used. This trap 17A is rotated in the direction of the arrow by a drive unit (not shown) to form a drainage state or a water sealing state. The trap 17 in the illustrated example is in the position in the water sealing state, and in the drainage state, it rotates so that the open end of the trap 17A faces the drain port 18. Note that the trap 17A is surrounded by a trap case (not shown) so that sewage and odors do not leak to the surroundings.

[0019] Also, the drainage mechanism is not limited to the siphon type and the movable type, and for example, a wash-down type may be used. Also, in the illustrated example, the toilet device 1 is shown as a tankless type directly connected to the water supply without a flushing tank (low tank), but a configuration with a flushing tank may also be used.

[0020] The toilet lid drive unit 22 and the toilet seat drive unit 26 are each composed of a motor or the like. The toilet lid drive unit 22 electrically opens and closes (raises and lowers) the toilet lid 20 when there is an instruction from the toilet lid operation unit 23, etc., and the toilet seat drive unit 26 electrically opens and closes (raises and lowers) the toilet seat 24 when there is an instruction from the toilet seat operation unit 27, etc.

[0021] In this specification, for both the toilet lid 20 and the toilet seat 24, a state of standing up substantially vertically is referred to as an open state, and a state of falling down substantially horizontally and being substantially parallel to the opening surface of the bowl 12 is referred to as a closed state.

[0022] The toilet device 1 includes a main body operation unit (not shown) provided on the toilet main body 10 and a remote control provided at a position separated from the toilet main body 10. These are provided with operation switches, operation buttons, etc. that can perform various operations and settings. As the remote control, an infrared communication type is preferably used. The remote control is provided with a transmission unit (not shown), and the toilet main body 10 is provided with a reception unit (not shown).

[0023] The toilet lid opening / closing instruction means in the present embodiment is means for outputting an opening or closing instruction for the toilet lid 20 in cooperation with hardware or software based on an operation instruction of the toilet lid operation unit 23. The toilet lid operation unit 23 is preferably arranged as an operation button on a remote control provided at a position separated from the toilet main body 10. The toilet lid opening / closing instruction means in the present embodiment outputs different instructions to the toilet lid drive unit 22 via a control unit 5 described later according to the opening / closing state of the toilet lid 20 when the toilet lid operation unit 23 is operated. When the toilet lid operation unit 23 is operated, the toilet lid opening / closing instruction means outputs an opening instruction for the toilet lid 20 if the toilet lid 20 is in the closed state, and outputs a closing instruction for the toilet lid 20 if the toilet lid 20 is in the open state. That is, the toilet lid operation unit 23 in the present embodiment functions as a toilet lid opening / closing button for switching the opening and closing of the toilet lid 20 with one button. Note that the toilet lid operation unit 23 may be configured to include two types of operation buttons, a toilet lid open button and a toilet lid close button, the toilet lid open button outputs an opening instruction for the toilet lid 20, and the toilet lid close button outputs a closing instruction for the toilet lid 20.

[0024] The toilet seat operation unit 27 is preferably arranged as an operation button on the remote control in the same manner as the toilet lid operation unit 23. The toilet seat operation unit 27 in the present embodiment outputs different instructions to the toilet seat drive unit 26 via a control unit 5 described later according to the opening / closing state of the toilet seat 24, outputs an opening instruction for the toilet seat 24 if the toilet seat 24 is in the closed state, and outputs a closing instruction for the toilet seat 24 if the toilet seat 24 is in the open state. That is, the toilet seat operation unit 27 in the present embodiment is a toilet seat opening / closing button for switching the opening and closing of the toilet seat 24 with one button. Note that the toilet seat operation unit 27 may be configured to include two types of operation buttons, a toilet seat open button and a toilet seat close button, the toilet seat open button outputs an opening instruction for the toilet seat 24, and the toilet seat close button outputs a closing instruction for the toilet seat 24.

[0025] When the toilet device 1 receives an instruction to close the toilet lid 20 from the toilet lid operation unit 23, if both the toilet lid 20 and the toilet seat 24 are in the open state, first the toilet seat 24 performs a closing operation. After closing (stopping in the closed state), the toilet lid 20 performs a closing operation so as to be interlocked with the closing operation of the toilet seat 24. Further, when the toilet seat operation unit 27 gives an instruction to open the toilet seat 24, if both the toilet seat 24 and the toilet lid 20 are in the closed state, first the toilet lid 20 performs an opening operation. After opening and stopping (stopping in the open state), the toilet seat 24 performs an opening operation so as to be interlocked with the opening operation of the toilet lid 20.

[0026] As the seating detection unit 28, for example, a load sensor built in the toilet seat 24, an infrared sensor provided near the rotation shaft portion of the toilet seat 24, or the like is adopted. These sensors detect the user's seating / standing up. As the toilet lid opening / closing detection unit 21 and the toilet seat opening / closing detection unit 25, those configured to detect the opening / closing state based on the opening angle are adopted.

[0027] The toilet device 1 may further be configured to include various functional devices such as a deodorizing device for deodorizing the inside of the bowl 12, a heating device for warming the toilet seat 24, and a local cleaning device for locally cleaning.

[0028] Furthermore, the toilet device 1 includes a cleaning operation unit 29 that outputs a cleaning instruction for the toilet cleaning unit 13. The cleaning operation unit 29 includes a large bowel cleaning button 29a and a small bowel cleaning button 29b that output a cleaning instruction to the toilet cleaning unit 13 via a control unit 5 described later.

[0029] Note that it is desirable that the cleaning operation unit 29 is arranged on either a main body operation unit provided on the toilet main body 10 or a remote controller provided at a position away from the toilet main body 10. Also, instead of providing both the large bowel cleaning button 29a and the small bowel cleaning button 29b, it may be configured to output a cleaning instruction with one cleaning button. That is, in that case, as the amount of cleaning water to the bowl 12, there is no distinction between a large capacity for large bowel and a small capacity for small bowel, and only one type of large capacity for large bowel is provided.

[0030] The toilet device 1 controls the above control targets (such as the water supply valve 16 of the toilet cleaning unit 13, the toilet lid driving unit 22, the toilet seat driving unit 26, etc.), and is provided with a control unit 5 that receives output signals from the cleaning operation unit 29, the toilet lid opening / closing detection unit 21, the toilet seat opening / closing detection unit 25, the seating detection unit 28, etc. This control unit 5 is composed of a processor such as a CPU or MPU and various programs. The toilet device 1 further includes a timing unit 6 that measures the time after the cleaning by the toilet cleaning unit 13 is completed, the time after the toilet lid 20 is opened, etc., and a power supply unit (not shown) that supplies power to the toilet device 1, etc.

[0031] In addition, the toilet device 1 is provided with a notification unit 7 composed of a speaker that notifies the abnormality, state, and guidance of the device by sound or voice synthesis. Note that the notification unit 7 may be configured to include a display such as an LED or a lamp that lights up or blinks instead of or in addition to the one that outputs sound.

[0032] Next, the basic operation of this toilet device 1 will be described based on the flowcharts of FIGS. 3 and 4. FIG. 3 describes the basic operation when there is an instruction to open / close the toilet lid by the toilet lid operation unit 23, and FIG. 4 describes the basic operation when there is a cleaning instruction by the cleaning operation unit 29.

[0033] In the following operation description, the detection of the opening / closing state of the toilet lid 20 and the opening / closing state of the toilet seat 24 are by respective detection units, but the description of the operation of these detection units will be omitted. Also, the opening / closing operations of the toilet lid 20 and the toilet seat 24 are by respective driving units, but the description of these driving units will be omitted. Also, as described above, the toilet lid operation unit 23 of the present embodiment is a toilet lid opening / closing button that switches the opening / closing of the toilet lid 20 with one button, and in the following operation description, it will also be described based on the toilet lid opening / closing instruction by the toilet lid operation unit 23, which is this toilet lid opening / closing button.

[0034] First, the operation of FIG. 3 will be described according to the flowchart shown in steps S100 to S119. In the following description, the operation steps of FIGS. 3 and 4, which are described as "step Sxxx", are abbreviated as only the symbol "Sxxx".

[0035] When the control unit 5 receives an opening / closing instruction of the toilet lid 20 from the toilet lid operation unit 23, the open / closed state of the toilet lid 20 is determined. If the toilet lid 20 is in the closed state, the toilet lid 20 performs an opening operation (N in S100, S101, S109). This opening operation of the toilet lid 20 is an operation performed by the user for using or cleaning the toilet device 1.

[0036] If the toilet lid 20 is in the open state, the control unit 5 determines whether the user is sitting on the toilet seat 24 (S102). If the user is sitting on the toilet seat 24, there is a risk that the toilet lid 20 may collide with the user due to the closing operation of the toilet lid 20. Therefore, the control unit 5 cancels the toilet lid opening / closing instruction in S100 and causes the notification unit 7 to notify, by sound or the like, that the toilet lid opening / closing instruction has been canceled (Y in S102, S110, S111).

[0037] If the user is not sitting, the control unit 5 determines whether a time T1 has elapsed from the end of the previous cleaning (the cleaning that starts after the start of the closing operation of the toilet lid 20 by the toilet lid operation unit 23) until the current closing instruction from the toilet lid operation unit 23 is received (N in S102, S103).

[0038] If the time T1 has elapsed, the control unit 5 determines whether a time T2 has elapsed from when the toilet lid 20 became open until the current closing instruction from the toilet lid operation unit 23 is received (Y in S103, S104).

[0039] If the time T2 has elapsed, the control unit 5 determines the open / closed state of the toilet seat 24. If the toilet seat 24 is in the closed state, the closing operation of the toilet lid 20 is executed (Y in S104, N in S105, S106). After the closing operation of the toilet lid 20 is completed and the toilet lid 20 is closed, it is notified by an electronic sound or the like that the washing of the bowl 12 will be performed, and then the washing operation of the bowl 12 by the toilet washing unit 13 is executed (S107, S108). If the toilet device 1 differentiates between a large capacity for defecation and a small capacity for urination, the large washing is performed in the washing operation of S108.

[0040] On the other hand, if the toilet seat 24 is in the open state, the closing operation of the toilet seat 24 is executed, and then the closing operation of the toilet lid 20 is executed (Y in S105, S116, S117). After the closing operation of the toilet lid 20 is completed and the toilet lid 20 is closed, it is notified by an electronic sound or the like that the washing of the bowl 12 will be performed, and the washing operation of the bowl 12 by the toilet washing unit 13 is executed (S118, S119). If the toilet device 1 differentiates between a large capacity for defecation and a small capacity for urination, the small washing is performed in the washing operation of S119.

[0041] In the above description, it is assumed that the washing starts after the toilet lid 20 in S106 and S117 is closed, but the washing by the toilet washing unit 13 may start while the closing operation of the toilet lid 20 is being executed.

[0042] On the other hand, when the time T1 has not elapsed in S103 or the time T2 has not elapsed in S104, first, the control unit 5 determines the open / closed state of the toilet seat 24 (N in S103 or N in S104, S112). If the toilet seat 24 is in the closed state, the closing operation of the toilet lid 20 is started (N in S112, S114). If the toilet seat 24 is in the open state, the closing operation of the toilet lid 20 is started after the closing operation of the toilet seat 24 is started (Y in S112, S113, S114). If the toilet lid 20 is closed, it is notified by a sound or the like that the toilet lid 20 has been closed (S115).

[0043] As described above, in the toilet device 1 of the present embodiment, when the control unit 5 receives a closing instruction from the toilet lid operation unit 23 (toilet lid opening / closing instruction means) while the toilet lid 20 is in the open state, the control unit 5 causes the toilet lid drive unit 22 to start the closing operation of the toilet lid 20, and then causes the toilet bowl cleaning unit 13 to start cleaning.

[0044] In this way, when a closing instruction for the toilet lid 20 is received by the toilet lid operation unit 23, cleaning is executed after the toilet lid 20 is closed. Therefore, it is not necessary for the user after excretion to give a cleaning instruction for the bowl 12 by the cleaning operation unit 29 again.

[0045] Further, in the toilet device 1 of the present embodiment, when the control unit 5 receives a closing instruction from the toilet lid operation unit 23 (toilet lid opening / closing instruction means) while the toilet seat 24 is in the open state, the control unit 5 causes the toilet seat drive unit 26 to start the closing operation of the toilet seat 24, and then causes the toilet lid drive unit 22 to start the closing operation of the toilet lid 20. Then, the control unit 5 causes the toilet bowl cleaning unit 13 to start small cleaning.

[0046] In this way, when a closing instruction for the toilet lid 20 is received by the toilet lid operation unit 23 and the toilet seat 24 is in the open state, since it is highly likely that a male user has urinated in the standing position, small cleaning is performed.

[0047] Further, in the toilet device 1 of the present embodiment, when the control unit 5 receives a closing instruction from the toilet lid operation unit 23 (toilet lid opening / closing instruction means) while the toilet lid 20 is in the open state within the time T1 after the cleaning started after the start of the closing operation of the toilet lid 20, the control unit 5 causes the toilet lid drive unit 22 to start the closing operation of the toilet lid 20. On the other hand, the control unit 5 does not cause the toilet bowl cleaning unit 13 to start cleaning.

[0048] In this way, if the time T1 has not elapsed, the toilet lid opening / closing instruction in S100 is determined that the user instructed to confirm the remaining dirt in the bowl 12 after cleaning, and no new cleaning is performed even if the toilet lid 20 is closed. Therefore, excessive cleaning of the bowl 12 is suppressed, and water charges, electricity charges, etc. are saved. Note that the time T1 is not particularly limited, but about 20 seconds is desirable.

[0049] In addition, when the control unit 5 of the present embodiment receives a closing instruction from the toilet lid operation unit 23 (toilet lid opening / closing instruction means) within the time T2 after the toilet lid 20 is opened, the control unit 5 causes the toilet lid drive unit 22 to start the closing operation of the toilet lid 20. On the other hand, the control unit 5 does not cause the toilet bowl cleaning unit 13 to start cleaning.

[0050] In this way, if the time T2 has not elapsed, it is determined that the opening / closing instruction of S100 is for the opening / closing operation of the toilet lid 20 to be repeated at short intervals for inspection of the toilet device 1, etc., and even if the toilet lid 20 is closed, no new cleaning is performed. Therefore, excessive cleaning of the bowl 12 is suppressed, and water charges, electricity charges, etc. are saved. Note that the time T2 is not particularly limited, but about 30 seconds is desirable.

[0051] Note that the above-described toilet device 1 is configured such that notification is performed by the notification unit 7 after the toilet lid is closed by the toilet lid opening / closing instruction or after the cancellation of the toilet lid opening / closing instruction, but it may be configured such that no notification is performed.

[0052] Note that the toilet lid operation unit 23 may be configured to include two types of operation buttons, a toilet lid open button and a toilet lid close button. In that case, when an open instruction is output by the toilet lid open button, if the toilet lid 20 is in the open state, the open instruction is canceled and the open state of the toilet lid 20 is maintained. On the other hand, when an open instruction is output by the toilet lid open button, if the toilet lid 20 is in the closed state, the toilet lid 20 is opened (S109 in FIG. 3). Also, when a close instruction is output by the toilet lid close button, if the toilet lid 20 is in the closed state, the close instruction is canceled and the closed state of the toilet lid 20 is maintained. On the other hand, when a close instruction is output by the toilet lid close button, if the toilet lid 20 is in the open state, the operation is executed along the flowchart from S102 in FIG. 3.

[0053] Next, the operation of FIG. 4 will be described according to the flowchart (S200 to S204).

[0054] When the control unit 5 receives a cleaning instruction from the cleaning operation unit 29, it determines whether cleaning is in progress after the toilet lid 20 is closed by the toilet lid operation unit 23 (S200, S201). If cleaning is not in progress, regardless of the open / closed state of the toilet lid 20, the cleaning operation of the bowl 12 by the toilet cleaning unit 13 is executed (N in S201, S202).

[0055] On the other hand, in S201, if cleaning is in progress, the cleaning instruction is canceled, and it is notified by an electronic sound or the like that the cleaning instruction has been canceled (Y in S201, S203, S204).

[0056] As described above, in the toilet device 1 of the present embodiment, the control unit 5 does not receive the cleaning by the cleaning operation unit 29 during the cleaning started after the start of the closing operation of the toilet lid 20.

[0057] In this way, even when the user operates the cleaning operation unit 29 in the usual habit when the cleaning after the toilet lid 20 is closed by the toilet lid operation unit 23 is being executed, no new cleaning is executed, so excessive cleaning is suppressed, and water charges, electricity charges, etc. are saved.

[0058] The toilet device 1 is not limited to the above, and the toilet seat 24 and the toilet lid 20 may be integrally replaceable. In particular, it may be a toilet device 3 to which a toilet seat device 30 as shown in FIG. 5 is retrofitted (or replaced). Based on FIGS. 5(a) and 5(b), the basic configuration of the toilet device 3 according to another embodiment of the present invention will be described. In the present embodiment, a movable trap 17A is illustrated in FIG. 5(b), but the present invention is also applicable to a toilet body having a siphon trap 17 (see FIG. 2(a)) or other types.

[0059] Specifically, the toilet device 3 includes a bowl 12, a toilet cleaning unit 13 that supplies cleaning water to the bowl 12 and cleans the inside of the bowl 12, a toilet seat device 30, and a cleaning operation unit 29 that outputs a cleaning instruction to the toilet cleaning unit 13. The toilet device 3 further includes a control unit 5, a timing unit 6, and a notification unit 7.

[0060] The toilet seat device 30 is a separable body that can be attached to and detached from the toilet body (the part excluding the toilet seat device 30) of the toilet device 3. The toilet seat device 30 includes a toilet lid 40, a toilet lid opening / closing detection unit 41, a toilet lid driving unit 42, a toilet lid operation unit 43, a toilet seat 44, a toilet seat opening / closing detection unit 45, a toilet seat driving unit 46, a toilet seat operation unit 47, a seating detection unit 48, a bowl cleaning operation unit 49, a toilet seat side control unit 35, and a notification unit 37. Also, signal transmission and reception are possible between the toilet seat device 30 and the toilet body.

[0061] Note that since the configuration of the toilet device 3 (toilet body) excluding the toilet seat device 30 is generally the same as that in FIG. 1, a detailed description is omitted. Also, the toilet lid 40, toilet lid opening / closing detection unit 41, toilet lid driving unit 42, toilet lid operation unit 43, toilet seat 44, toilet seat opening / closing detection unit 45, toilet seat driving unit 46, toilet seat operation unit 47, and seating detection unit 48 provided in the toilet seat device 30 are also generally the same as those in FIG. 1, and their descriptions are omitted.

[0062] The toilet seat device 30 in FIG. 5 is configured to be able to output a cleaning instruction for the bowl 12 to the toilet cleaning unit 13 from the toilet seat device 30 side. Specifically, when there is an instruction for cleaning from the bowl cleaning operation unit 49 of the toilet seat device 30, the toilet seat side control unit 35 receives this and controls the toilet cleaning unit 13 through the control unit 5 on the toilet body side so that the bowl 12 can be cleaned. Also, the toilet seat side control unit 35 may be directly configured to control the toilet cleaning unit 13.

[0063] Note that as shown in FIG. 5, the toilet device 3 is configured to include not only the bowl cleaning operation unit 49 on the toilet seat device 30 side but also the cleaning operation unit 29 on the main body side. That is, the one in FIG. 5 is configured such that a cleaning instruction can be given by either the cleaning operation unit 29 or the bowl cleaning operation unit 49. Also, it may be configured such that a cleaning instruction can be given only by the bowl cleaning operation unit 49 without providing the cleaning operation unit 29 on the main body side. It is desirable that the bowl cleaning operation unit 49 also has a large bowel cleaning button and a small bowel cleaning button.

[0064] When there is an instruction to open or close the toilet lid by the toilet lid operation unit 43, this toilet device 3 can perform the operations shown in Fig. 3, similar to the toilet device 1 in Fig. 1. That is, when the toilet lid 40 is in the open state and the toilet seat device 30 receives an instruction to close the toilet lid 40, the toilet seat side control unit 35 causes the toilet lid 40 to perform a closing operation. After the toilet lid 40 is closed, a cleaning instruction is output to the toilet cleaning unit 13.

[0065] When there is a cleaning instruction, similar to the toilet device 1 in Fig. 1, the operations shown in Fig. 4 can be performed. That is, when there is a cleaning instruction, the toilet seat side control unit 35 outputs a cleaning instruction if the bowl 12 is not being cleaned, and cancels the cleaning instruction if the bowl 12 is being cleaned.

[0066] As described above, the toilet seat device 30 includes a toilet seat 44, a toilet seat opening / closing detection unit 45 that detects the opening and closing of the toilet seat 44, a toilet seat driving unit 46 that opens and closes the toilet seat 44, and a toilet lid 40. Further, the toilet seat device 30 includes a toilet lid opening / closing detection unit 41 that detects the opening and closing of the toilet lid 40, a toilet lid driving unit 42 that opens and closes the toilet lid 40, and a toilet seat side control unit 35, and is attached to the toilet body that performs the cleaning operation of the bowl 12. When the toilet seat side control unit 35 receives a closing instruction from the toilet lid operation unit 43 (toilet lid opening / closing instruction means) when the toilet lid 40 is in the open state, the toilet lid driving unit 42 is caused to start the closing operation of the toilet lid 40, and then a cleaning instruction is output to the toilet body.

[0067] In this way, if the user after excretion executes the closing instruction of the toilet lid 40 by the toilet lid operation unit 43, cleaning is performed after the toilet lid 40 is closed, so the user does not need to give a cleaning instruction for the bowl 12 by the cleaning operation unit 29 or the bowl cleaning operation unit 49.

[0068] Also, when the toilet seat side control unit 35 receives a closing instruction from the toilet lid operation unit 43 (toilet lid opening / closing instruction means) when the toilet seat 44 is in the open state, the toilet seat driving unit 46 is caused to start the closing operation of the toilet seat 44. After that, the toilet seat side control unit 35 causes the toilet lid driving unit 42 to start the closing operation of the toilet lid 40, and then outputs a small cleaning instruction to the toilet body. That is, this operation corresponds to S116, S117, S118, and S119 in Fig. 3.

[0069] Also, during the cleaning that starts after the start of the closing operation of the toilet lid 40, the toilet seat side control unit 35 does not output a cleaning instruction to the toilet body. That is, this operation corresponds to that shown in FIG. 4.

[0070] Also, when the toilet seat side control unit 35 receives a closing instruction from the toilet lid operation unit 43 (toilet lid opening / closing instruction means) while the toilet lid 40 is in the open state within the time T1 after the cleaning that starts after the start of the closing operation of the toilet lid 40 ends, the toilet seat side control unit 35 causes the toilet lid drive unit 42 to start the closing operation of the toilet lid 40. On the other hand, the toilet seat side control unit 35 does not output a cleaning instruction to the toilet body. That is, this operation corresponds to N and S114 of S103 in FIG. 3.

[0071] Also, when the toilet seat side control unit 35 receives a closing instruction from the toilet lid operation unit 43 (toilet lid opening / closing instruction means) within the time T2 after the toilet lid 40 becomes open, the toilet seat side control unit 35 causes the toilet lid drive unit 42 to start the closing operation of the toilet lid 40 and does not output a cleaning instruction to the toilet body. That is, this operation corresponds to N and S114 of S104 in FIG. 3.

[0072] Regarding various notifications such as the notification after the closing of the toilet lid 40 and the notification after the cancellation of the toilet lid opening / closing instruction in the operation of the toilet device 3, it may be performed by either the notification unit 37 of the toilet seat device 30 or the notification unit 7 of the toilet body.

[0073] Note that the toilet seat device 30 is not limited to that shown in FIG. 5. The toilet seat device 30 may be configured to include, for example, a local cleaning device, or may be configured to have a toilet seat operation unit (not shown) capable of various (for example, local cleaning device) operations and settings.
