The toilet bowl devices 1 and 3 described below are based on the principle of cleaning the bowl 12 in the closed state of the toilet lids 20 and 40 from the viewpoint of preventing the diffusion of contaminants contained in the excrement. Therefore, when the toilet lids 20 and 40 are open when the cleaning instruction is given, the toilet lids 20 and 40 start to be closed by the toilet lid drive units 22 and 42, and after the toilet lids 20 and 40 are closed, the toilet lids 20 and 40 are closed. A sequence operation is executed in which the cleaning operation by the toilet bowl cleaning unit 13 is performed. The toilet bowl devices 1 and 3 are designed so that such a sequence operation is not executed in the case of a cleaning instruction by pre-cleaning.

First, the outline of the toilet bowl device 1 according to the present embodiment will be described below. The toilet device 1 is a device having the configurations shown in FIGS. 1 and 2, and is capable of executing the basic operations shown in FIGS. 3 to 5.

The toilet device 1 includes a bowl 12, a toilet cleaning unit 13 that supplies washing water to the bowl 12 to clean the inside of the bowl 12, a toilet lid 20, and a toilet lid opening / closing detection unit 21 that detects the opening / closing of the toilet lid 20. A toilet lid driving unit 22 that opens and closes the toilet bowl 20 is provided. Further, the toilet device 1 includes a cleaning instruction means for outputting a cleaning instruction to the toilet cleaning unit 13 and a control unit 5. Here, as the cleaning instruction means, there are those by the cleaning operation of the user and those automatically based on the operation of the user, and the details will be described later.

In this toilet device 1, when a cleaning instruction is given by the cleaning instruction means, in principle, when the toilet lid 20 is open as described above, the toilet lid 20 closing operation by the toilet lid driving unit 22 starts. do. The toilet device 1 is allowed to perform a sequence operation in which the toilet cleaning unit 13 performs a cleaning operation after the toilet lid 20 is closed.

Further, the cleaning instruction by the cleaning instruction means of the toilet device 1 includes a cleaning instruction by pre-cleaning to bring the bowl 12 into a predetermined pooled water state. The details of the predetermined pooled water state will be described later.

As shown in FIG. 3, when a cleaning instruction is given by pre-cleaning, the control unit 5 exceptionally prohibits the sequence operation in the open state of the toilet lid 20, and the toilet bowl is irrespective of the open / closed state of the toilet lid 20. The cleaning unit 13 is allowed to perform the cleaning operation of the bowl 12.

Next, the detailed configuration, structure, and basic operation of the toilet bowl device 1 will be described with reference to FIGS. 2 (a) and 2 (b).

The toilet device 1 shown in FIG. 2A is a sitting type Western-style toilet device fixed to a floor, a wall, or the like in a toilet space. The toilet body 10 of the toilet device 1 is provided so that the bowl 12 opened upward is surrounded by the skirt portion 11, and the upper side of the bowl 12 is vertically laid down with respect to the opening surface of the bowl 12, respectively. Is provided with a toilet seat 24 and a toilet lid 20 that rotate.

In the internal space of the skirt portion 11, a toilet bowl cleaning portion 13 that discharges the sewage in the bowl 12 and supplies washing water into the bowl 12 from the water supply port 2 to clean the inside of the bowl 12 is arranged. The toilet bowl cleaning unit 13 has a water supply mechanism and a drainage mechanism.

The water supply mechanism is arranged in the middle of the water supply port 2, the wash water supply path 15 that supplies the wash water supplied from the water supply port 2 into the bowl 12 from the discharge port 15b, and the wash water supply path 15 to the bowl 12. It is provided with a water supply valve 15a for supplying or shutting off the water supply of the above.

Further, in the washing water supply path 15, on the downstream side (discharge port 15b side) of the water supply valve 15a, a foam mixing unit 8 for mixing bubbles and bubbles due to chemicals with the washing water is provided. In this toilet device, the foam mixing unit 8 is composed of a bubble mixing unit 81 that mixes air bubbles in the washing water and a medicine mixing unit 84 that mixes the medicine in the washing water. In the toilet device 1, when a cleaning instruction is given by the cleaning instruction means, the sequence operation includes an operation in which the cleaning water mixed with bubbles is supplied to the bowl 12 by the foam mixing unit 8 to bring it into a stored water state. ..

The bubble mixing section 81 shown in FIG. 2B includes a rapid pressure changing section 82 and a gas supply valve 83. The rapid pressure changing portion 82 includes an inflow portion 821 having a throttle portion 821a whose hole diameter gradually decreases, a shear portion 822 which is a Venturi tube, and an outflow portion 823 including a mesh portion 823a. The inflow portion 821, the shear portion 822, and the outflow portion 823 are each substantially cylindrical members. The rapid pressure changing portion 82 is connected to each of the inflow portion 821, the shear portion 822, and the outflow portion 823 to form a washing water flow path 82a through which the washing water from the washing water supply passage 15 flows.

The gas supply valve 83 supplies or shuts off the gas to the shear portion 822. When the valve is opened, the gas supply valve 83 supplies gas from the gas supply source to the upstream side of the shear portion 822 through the hole 822d formed on the side peripheral surface of the shear portion 822. In the present embodiment, the gas mixed in the washing water by the bubble mixing unit 81 is the air around the gas supply valve 83. When the inflow portion 821 and the shear portion 822 are connected, the upstream side of the shear portion 822 covers the outer peripheral portion 821aa of the throttle portion 821a of the inflow portion 821, and the hole 822d is from the discharge port 821b of the inflow portion 821. Is also configured to be slightly upstream. The control unit 5 adjusts the amount of gas mixed in the washing water by controlling the opening time of the gas supply valve 83.

The inflow portion 821 includes a throttle portion 821a whose diameter gradually decreases. The flow velocity of the washing water is increased by the throttle portion 821a, and the washing water flowing through the washing water flow path 82a becomes a jet jet. Then, the gas supplied from the gas supply valve 83 is supplied to the vicinity of the discharge port 821b of the inflow section 821. As a result, a shearing force is generated at the interface between the gas and the washing water of the jet jet, and bubbles are generated.

The shear portion 822 includes an upstream hole 822a on the inflow portion 821 side, a throttle portion 822b having a diameter smaller than that of the upstream hole 822a, and a downstream hole 822c whose diameter gradually increases from the throttle portion 822b. Further, a recess 822e is formed between the upstream hole 822a and the outer peripheral portion 821ba of the discharge port 821b of the inflow portion 821. In this recess 822e, a negative pressure is generated by the washing water flowing through the washing water flow path 82a, and the gas supplied from the gas supply valve 83 can be efficiently mixed with the washing water flowing through the washing water flow path 82a by the ejector effect. can.

In the throttled portion 822b of the sheared portion 822, the flow velocity of the washing water mixed with the gas becomes high, and the pressure of the washing water becomes low, so that the gas in the washing water expands. Then, in the downstream hole 822c, the pressure of the gas is continuously increased and the gas is continuously contracted. At this time, the gas receives a shearing force and is divided into fine bubbles having a bubble diameter of 100 to 500 μm.

The washing water mixed with fine bubbles in the sheared portion 822 passes through the mesh portion 823a of the outflow portion 823. By passing through the mesh of the mesh portion 823a, the fine bubbles are further divided and the bubble diameter of the fine bubbles is further reduced. The washing water in which the fine bubbles are mixed in this way flows from the bubble mixing portion 81 and flows back into the washing water supply path 15.

The drug mixing unit 84 mixes a predetermined amount of the drug into the washing water supply path 15. The drug mixing unit 84 is arranged in the middle of the tank 84a for storing the drug, the drug supply path 84b connected to the wash water supply path 15, and the drug supply path 84b, and supplies the drug to the wash water supply path 15. Alternatively, it is provided with a drug supply valve 84c that shuts off. In this embodiment, the agent is a surfactant. Further, the fragrance is mixed in the chemical so that the fragrance is further mixed in the washing water. In the present embodiment, the drug mixing unit 84 is arranged on the downstream side of the bubble mixing unit 81, but may be arranged on the upstream side of the bubble mixing unit 81. The washing water mixed with the chemicals and air bubbles is discharged into the bowl 12 from the discharge port 15b of the washing water supply path 15.

In this way, when the washing water mixed with the drug and the bubbles is supplied to the bowl 12, the bubbles collide with the surface of the bowl 12. At this time, the dirt in the bowl 12 is removed by the ultrasonic waves generated by the burst of the bubbles. Further, since the chemical is supplied to the washing water, the surface of the bowl 12 is further washed. Since the medicine contains a fragrance, the user can comfortably use the toilet bowl device 1 due to the fragrance component of the fragrance. Further, since the fine bubbles stay in the washing water for a long time, the surface of the bowl 12 can be washed with the bubbles for a long time.

The foam mixing unit 8 is not limited to the above-mentioned one. For example, the foam mixing unit 8 may be configured with only one of the bubble mixing unit 81 and the drug mixing unit 84. Further, the gas supply valve 83 may be provided with a discharge section, and the ozone gas generated by the discharge may be supplied to the shear section 822, or the gas having other bactericidal effects may be supplied. There may be. Further, an air pump may be provided instead of the gas supply valve 83, and the gas may be supplied to the shear portion 822 by driving the air pump. Further, the structure in which air bubbles are mixed in the washing water is not limited to the above-mentioned one or the illustrated one. In addition, the toilet bowl device 1 may contain a fragrance, but may not contain it. Further, the agent is not limited to the surfactant, and may be an antibacterial agent using silver ion, ozone, chlorine or the like, or any other agent may be used as the agent.

The drainage mechanism has a movable trap 17 connected so as to extend rearward from the bottom of the bowl 12. The trap 17 is rotated in the vertical direction by a driving unit (not shown) to form a drainage state or a water sealing state. The trap 17 drawn by the solid line in FIG. 2 (a) is in the sealed state, and the trap 17 drawn by the two-dot chain line in FIG. 2 (a) has the open end 17a facing the drain port 18. It shows the position in the rotated drainage form. The trap 17 is surrounded by a trap case 19 so that sewage and odor do not leak to the surroundings.

The drainage mechanism is not limited to the movable trap 17, and the trap 17, which is a bent tubular body connected so as to extend rearward from the bottom of the bowl 12, extends downward to the drainage port 18. It may be connected to. This type of drainage mechanism includes a siphon type, a siphon zet type, a siphon vortex type, etc., and is in a drainage state in which the stored water is drained together with the filth in the bowl 12 by the siphon action or a sealed state in which the stored water is stored in the bowl 12. Is considered to be the mechanism by which is formed.

Further, the drainage mechanism is not limited to the siphon type and the movable type, and may be, for example, a wash-off type. Further, in the figure, an example in which the toilet bowl device 1 is a tankless type directly connected to the water supply without a water washing tank (low tank) is shown, but it may be configured to have a water washing tank.

Further, the toilet device 1 may be provided with various functional devices such as a local cleaning device for cleaning the user's local area, a deodorizing device for deodorizing the inside of the bowl 12, and a heating unit for heating the toilet seat 24.

Further, the toilet device 1 includes a cleaning operation unit 29 that outputs a cleaning instruction to the toilet cleaning unit 13. The cleaning operation unit 29 includes a stool cleaning button 29a and a urine cleaning button 29b that output cleaning instructions to the toilet bowl cleaning unit 13 via a control unit 5 described later. When the stool cleaning button 29a and the stool cleaning button 29b are operated, the toilet bowl cleaning unit 13 discharges the excrement and the like in the bowl 12 together with the cleaning water and flushes the cleaning water to clean the inside of the bowl 12. During the cleaning operation, the cleaning water containing bubbles by the foam mixing unit 8 is supplied so that the water level of the pooled water in the bowl 12 becomes the standard level L1 as shown in FIG. 2 (a).

Further, the cleaning operation unit 29 is provided with a pre-cleaning button 29c that outputs a cleaning instruction by pre-cleaning to bring the bowl 12 into a predetermined pooled water state. The toilet device 1 uses the pre-cleaning button 29c as a stool collection mode button 29ca to execute a stool collection mode in which the water level of the bowl 12 is set to a low water level L2, which is a water level lower than the standard level L1 during the cleaning operation by the toilet bowl cleaning unit 13. Is equipped with. Further, the toilet device 1 has a pre-cleaning button 29c that prohibits the operation of the foam mixing unit 8 and supplies the bowl 12 with cleaning water that does not contain air bubbles or bubbles such as chemicals by the foam mixing unit 8.

Further, the toilet device 1 may be provided with a mode setting function by providing a stool collection mode setting switch or a communication mode setting switch in place of or in addition to the pre-cleaning button 29c. When these modes are set, the first cleaning after that is pre-cleaning, and as will be described later, stool collection and stool status confirmation can be performed without inconvenience while the mode is set. The pre-cleaning button 29c performs pre-cleaning as soon as it is operated, but the mode setting function does not perform pre-cleaning immediately after the mode is set, but the cleaning operation unit 29 after the mode is set. Is operated to perform pre-cleaning. The mode of the stool collection mode setting switch and the communication mode setting switch may be set by operating a common setting switch.

When any of the pre-cleaning modes is being set (ON), the toilet device 1 having the mode setting function is set by prohibiting cleaning by sequence operation when the cleaning operation unit 29 is operated. Perform pre-cleaning. Then, in the case of performing the cleaning by the sequence operation from the pre-cleaning, the cleaning by the sequence operation is executed by operating the cleaning operation unit 29 after turning off the setting of the pre-cleaning mode.

The pre-cleaning mode setting by the mode setting function may be operated by a button or the like provided on the toilet bowl main body 10, or may be operated by a button or the like provided on the remote controller provided at a position away from the toilet bowl main body 10. .. In addition, the setting switching of the pre-cleaning mode may be operated by introducing a dedicated application to a mobile terminal such as a smartphone. Further, if the cleaning operation unit 29 is not operated even after a lapse of a certain period of time after the pre-cleaning mode is selected, the pre-cleaning mode setting may be automatically turned off.

The stool collection mode is a mode in which the water level is kept low and stool collection is facilitated by supplying the washing water to the bowl 12 until the water level of the stored water reaches the low water level L2 after the bowl 12 is washed. On the other hand, the general mode is a mode in which the bowl 12 is washed and the foam-free washing water is supplied to the bowl 12 by the foam mixing unit 8 to make it easier to check the state of stool (urine / stool) after excretion. Is. In the toilet bowl device 1, in the case of the stool collection mode, the washing water containing bubbles by the foam mixing unit 8 is supplied to the bowl 12. Further, in the case of the communication mode, the washing water is supplied to the bowl 12 until the water level of the stored water reaches the standard level L1.

It is desirable that the cleaning operation unit 29 is arranged in either the main body operation unit provided in the toilet bowl main body 10 or the remote controller provided at a position away from the toilet bowl main body 10. Further, it is also possible to output a cleaning instruction with one cleaning button without providing both the stool cleaning button 29a and the urine cleaning button 29b. That is, in that case, the amount of washing water in the bowl 12 is not distinguished between the large capacity for stool and the small capacity for urine, and is only one type of the large capacity for stool.

The toilet device 1 includes a control unit 5 that controls the control target (toilet bowl cleaning unit 13 such as water supply valve 15a and trap 17, toilet lid drive unit 22, toilet seat drive unit 26, foam mixing unit 8, etc.). While controlling the control target, the control unit 5 receives output signals from the cleaning operation unit 29, the toilet lid open / close detection unit 21, the toilet seat open / close detection unit 25, the seating detection unit 28, and the like. The control unit 5 includes a processor such as a CPU and an MPU and various programs. The toilet device 1 further includes a time measuring unit 6 for measuring the time after the pre-cleaning is performed, and a power supply unit (not shown) for supplying power to the toilet device 1.

Further, the toilet bowl device 1 includes a notification unit 7 composed of a speaker or the like that notifies an abnormality or state of the device and guidance by sound or voice synthesis. The notification unit 7 may be configured to include a display such as an LED or a lamp for lighting or blinking in place of or in addition to the sound output unit.

Next, the basic operation of the toilet device 1 will be described with reference to the flowcharts of FIGS. 3 to 5. The following basic operations are examples, and are not limited to these. Further, in the following description, in FIGS. 3 and 4, the cleaning instruction is based on the operation of the cleaning operation unit 29, and in FIG. 5, the seating detection unit 28 detects that the user has left the toilet seat 24. , The washing instruction is given by triggering the change from sitting to leaving.

First, the operations of FIGS. 3 and 4 will be described with reference to the flowcharts shown in steps S100 to S126. In the following description, the operation step of FIGS. 3 to 5 described as "step SXXX" is abbreviated as "SXXX" having only a code.

When a cleaning instruction is received, it is first notified by the notification unit 7 by, for example, an electronic sound "beep" (S100, S101). It is determined whether it is an instruction by pre-cleaning, and if it is not a cleaning instruction by pre-cleaning, the open / closed state of the toilet lid 20 is determined, and if it is in the closed state, the bowl 12 is immediately washed. (N of S102, N of S103, S109). Further, even when the toilet lid 20 is seated on the toilet seat 24 in the open state, the bowl 12 is washed (Y in S103, Y in S104, S109).

Although not shown in FIG. 3, the toilet lid 20 opens after the cleaning is completed, and after a certain period of time after the opening, the opened toilet lid 20 closes, closes, and stands by. It may be in a state (a state in which the toilet lid 20 is closed).

The opening operation of the toilet lid 20 after cleaning is an operation executed for the user to confirm the residual filth in the bowl 12 after cleaning. That is, the user does not need to manually open the toilet lid 20 to check the inside of the bowl 12 after cleaning.

Instead of the delay for a certain period of time, the standby state may be returned at the timing when the human sensor no longer detects a person. Of course, since the user can close the toilet lid 20 with the toilet lid operation unit 23, it is not necessary to automatically return to the standby state.

If the toilet seat 24 is closed and not seated, the toilet lid 20 is closed (N in S104, N in S105, S107). If the toilet seat 24 is in the open state without being seated, the toilet seat 24 is closed, and the toilet lid 20 is closed after the toilet seat 24 is closed or in conjunction with the closing operation of the toilet seat 24. (N of S104, Y of S105, S107). Then, when the toilet lid 20 is closed, the closing of the toilet lid 20 is notified by an electronic sound "beep" or the like different from that at the time of the cleaning instruction, and the bowl 12 is washed (S108, S109). It should be noted that the closing of the toilet lid 20 may not be notified, but the cleaning may be notified. That is, in that case, the notification is also made when the toilet lid 20 is closed (N in S103) after the cleaning instruction.

As described above, the above operation is executed when the cleaning instruction is not pre-cleaning. That is, the toilet device 1 is premised on cleaning with the toilet lid 20 closed, and when the cleaning instruction means gives a cleaning instruction, if the toilet lid 20 is open, the toilet lid 20 closes. After closing the toilet lid 20, a sequence operation is executed in which the toilet bowl cleaning unit 13 performs a cleaning operation. Of course, if the toilet seat 24 is open, the closing operation of the toilet seat 24 is executed prior to the closing operation of the toilet lid 20.

Further, in the toilet device 1, the washing water mixed with the bubbles by the foam mixing unit 8 is supplied to the bowl 12 to be in a pooled water state, and the bowl 12 is sealed during the washing operation. The operation of setting the water level (standard level L1) is included in the above sequence operation.

On the other hand, when the cleaning instruction is by pre-cleaning, the above sequence operation is prohibited. That is, regardless of the open / closed state of the stool lid 20, it is notified by an electronic sound "beep pee" or the like that pre-cleaning is performed instead of the above sequence operation, and it is determined whether the pre-cleaning is in the stool collection mode or the communication mode. (Y, S110, S111 of S102). If the pre-cleaning is in the stool collection mode, the washing water containing bubbles by the foam mixing unit 8 is supplied until the water level becomes low L2, which is a water level lower than the standard level L1 (Y, S112, S113 of S111). In addition, as in the general mode described later, the toilet device 1 may prohibit the operation of the foam mixing unit 8 and supply the washing water containing no foam by the foam mixing unit 8 even in the stool collection mode.

The toilet device 1 has two modes, a stool collection mode and a communication mode, as pre-cleaning. Therefore, in S111, if the pre-cleaning is not in the stool collection mode, the pre-cleaning in the through mode is executed, the operation of the foam mixing unit 8 is prohibited, and the cleaning water containing no bubbles by the foam mixing unit 8 becomes the standard level L1. Is supplied up to (N of S111, S114). In the toilet device 1, by closing the gas supply valve 83 and the drug supply valve 84c, the washing water containing no bubbles by the foam mixing unit 8 is supplied to the bowl 12. In addition, as long as the medicine does not generate bubbles, the toilet device 1 may include the medicine by the medicine mixing unit 84 even in the general mode.

After the low water level pooled water state of S113 or the cleaning water containing no bubbles due to the pre-cleaning of S114 is supplied to the bowl 12, the time measurement after the pre-cleaning is performed by the timing unit 6 is started (S115). ). In the toilet device 1, if there is no cleaning instruction by the cleaning instruction means between the time when the pre-cleaning is performed and the predetermined time elapses, the notification unit 7 notifies that the time has been reached by an electronic sound "pee" or the like. (N of S116, Y of S117, S118). Examples of the cleaning instruction by the cleaning instruction means in this case include operation by the stool cleaning button 29a or the urine cleaning button 29b. In the toilet device 1, the predetermined time is set to about 20 minutes, but the present invention is not limited to this. Then, the above sequence operation is executed until the washing water in which the bubbles are mixed by the foam mixing unit 8 reaches the water level (standard level L1) of the reservoir water that seals the bowl 12 as shown in FIG. 2 (a). It is supplied (S119 to S125). In the cleaning when the time is up, the toilet device 1 performs the same cleaning as when the cleaning instruction is given by the stool cleaning button 29a. If cleaning by the stool cleaning button 29a or the urine cleaning button 29b is instructed between the start of the timer and the time-up, the timer is reset and the above sequence operation is executed (S126, S119 to). S125). The operation of S119 to S125 in FIG. 4 is the same as that of S103 to S109 in FIG.

As described above, the toilet device 1 may be provided with a stool collection mode setting switch or a communication mode setting switch to provide a mode setting function. When pre-cleaning is performed by the mode setting function, the timer is reset and the above sequence operation is executed by instructing cleaning by the cleaning operation unit 29 after the mode setting function is switched from on to off (S126). , S119-S125). Further, the timer may be reset when the mode setting function is switched from on to off. Further, when a predetermined time has elapsed with the mode setting turned on after the pre-cleaning by the mode setting function is performed, the cleaning by the sequence operation may be performed and the pre-cleaning mode setting may be automatically switched from on to off. The toilet device 1 having the mode setting function does not have to measure the time by the time measuring unit 6 of S115. By doing so, during the mode setting, pre-cleaning is performed to bring the water to a predetermined state according to the cleaning instruction by the cleaning means, so that it is possible to collect stools and check the condition of stools without any inconvenience. ..

In this way, the toilet device 1 makes it easy to check the stool collection mode or the state of stool (urine / stool) after excretion, which keeps the water level low and facilitates stool collection when a cleaning instruction is given by pre-cleaning. The toilet mode is executed. After the pre-cleaning is performed, the toilet lid 20 is not automatically closed even if it is detected to be separated from the toilet seat 24, so it is not necessary to open the toilet lid 20 again to collect stool or check the condition of the stool, which is convenient. The sex becomes high.

Further, the toilet device 1 is configured to perform cleaning by the cleaning instruction means when about 20 minutes, which is a predetermined time, has elapsed from the pre-cleaning. As a result, after the pre-cleaning in the stool collection mode is performed and the water level becomes low L2, the water surface of the stored water evaporates and the sealing water is prevented from being cut off because the cleaning instruction by the cleaning instruction means is not performed. Be done. Further, when a predetermined time elapses after the pre-cleaning in the general mode is performed, the washing water containing the foam by the foam mixing unit 8 is supplied, so that the inside of the bowl 12 is further cleaned by the foam of the foam mixing unit 8. .. Further, as shown in the basic operation of FIG. 5 described later, the toilet device 1 does not perform cleaning even if it detects that it has left the toilet seat 24 in a predetermined pooled water state formed by pre-cleaning. It has become. Therefore, even if the user misunderstands that the toilet seat 24 will be cleaned if the user leaves the toilet seat 24 and forgets the cleaning instruction by the cleaning instruction means, the cleaning is automatically executed after a predetermined time has elapsed.

The toilet device 1 is configured to include two modes, a stool collection mode and a communication mode, as pre-cleaning, but it may be configured to include only one of them, and the pre-cleaning is limited to these. There is no such thing. Further, the toilet device 1 is automatically washed after a predetermined time has elapsed from the pre-cleaning, but the cleaning is not limited to this. For example, the toilet seat 24 is seated even if the time is up. If it is in the state of being present, the washing may be postponed until the person leaves the seat. In that case, the user may be configured to perform cleaning after providing a delay for a certain period of time after detecting leaving so that there is a grace period until the user collects stool or confirms the condition of stool. Further, the toilet device 1 is configured to start the timer after the pre-cleaning is performed, but after the pre-cleaning, the timer starts after detecting the change in the sitting state of the toilet seat 24. It may be a configuration. Further, when the toilet device 1 is equipped with a motion sensor and it is detected that the toilet has left the toilet space in which the toilet device 1 is installed without giving a cleaning instruction by the cleaning instruction means after performing pre-cleaning. It may be configured to perform cleaning automatically.

Next, the basic operation shown in FIG. 5 will be described with reference to the flowcharts shown in S200 to S204.
When the disengagement of the toilet seat 24 is detected, it is determined whether the inside of the bowl 12 is in a predetermined pooled water state (S200, S201). The predetermined reservoir water state is the state of the reservoir water formed by the pre-cleaning performed by operating the pre-cleaning button 29c. For this determination, for example, the pre-cleaning button 29c may be operated and then the stool cleaning button 29a or the urine cleaning button 29b may not be operated. Further, it may be determined that the inside of the bowl 12 is in a predetermined stored water state by the state in which the time measuring unit 6 measures the time after the pre-cleaning is performed. If the stored water is not in a predetermined state, the toilet lid 20 is closed, and if the toilet lid 20 is closed, the closing of the toilet lid 20 is notified by an electronic sound "beep" or the like different from that at the time of the cleaning instruction. , The bowl 12 is washed (N, S202, S203, S204 of S201). On the other hand, if the inside of the bowl 12 is in a predetermined pooled water state formed by pre-washing, the state is maintained without closing the toilet lid 20 and not washing even if the leaving is detected (S201). N).
