Description

The present invention relates to a toilet device having a toilet lid and a toilet lid drive unit, and a toilet seat device having a toilet lid and a toilet lid drive unit, which is used by attaching to the toilet bowl body.

Recently, from the viewpoint of preventing the diffusion of pollutants contained in the excrement when cleaning the toilet bowl (bowl), excrete the pollutants contained in the feces excreted in the bowl so that the droplets containing the pollutants do not scatter to the outside of the toilet bowl. It is later encouraged to wash the bowl with the toilet lid closed.

In order to ensure that the bowl is washed with the toilet lid closed, the toilet lid is first electrically closed by the toilet lid drive unit when a cleaning instruction is given, and then the bowl is washed. Devices have been proposed (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 07-158142

However, such an electrically opened and closed toilet lid may not operate from the beginning or in the middle due to various factors that cause the toilet lid to be closed triggered by a cleaning instruction. In that case, as a matter of course, if the sequence operation of cleaning after the toilet lid is closed is followed, the subsequent bowl cleaning is not performed forever.

For example, if there is an obstacle in front of the standing toilet lid, or if the toilet lid drive unit or the toilet lid is out of order, the toilet lid will not be closed. As an obstacle, for example, in order to confirm the flow of excrement, it is conceivable that the user himself / herself stops the toilet lid to be closed after a cleaning instruction by operating a button or the like. In this way, it is inconvenient that the closing operation of the toilet lid is stopped by an obstacle (such as a human hand) and the bowl is not washed forever.

The present invention has been proposed in consideration of such circumstances, and an object thereof is a toilet bowl device in which a bowl is washed even if the closing operation of the toilet lid executed by a cleaning instruction is not properly performed. And to provide a toilet seat device.

In order to achieve the above object, the toilet device of the present invention includes a bowl, a toilet cleaning unit that supplies washing water to the bowl and cleans the inside of the bowl, a toilet lid, and a toilet that detects the opening and closing of the toilet lid.

If the toilet lid is closed, cleaning by the toilet bowl cleaning unit is executed, and the control unit receives the cleaning instruction, and if the toilet lid is open, the cleaning is performed for a predetermined time. If the timer is activated and the closure of the toilet lid is detected before the predetermined time elapses, the toilet bowl cleaning unit is started to wash at that timing, while the toilet lid is closed when the predetermined time elapses. If it is not detected, the toilet bowl cleaning unit starts cleaning at that timing.

The other toilet device of the present invention includes a bowl, a toilet cleaning unit that supplies washing water to the bowl to clean the inside of the bowl, a toilet lid, and a toilet lid opening / closing detection unit that detects the opening / closing of the toilet lid. A toilet device including a toilet lid driving unit that opens and closes the toilet lid, a cleaning instruction means for outputting a cleaning instruction to the toilet bowl cleaning unit, a timing unit, and a control unit, and cleaning by the cleaning instruction means. If the toilet lid is open when instructed, the toilet lid driving unit starts closing the toilet bowl before cleaning by the toilet bowl cleaning unit, while the toilet lid is closed. For example, the toilet bowl cleaning unit is configured to perform cleaning, and the control unit activates a timer for a predetermined time if the toilet lid is open when the cleaning instruction is received, and the predetermined time. It is characterized in that the toilet bowl cleaning unit starts cleaning after a lapse of time.

Further, the toilet seat device of the present invention includes a toilet seat, a toilet lid, a toilet lid opening / closing detection unit that detects the opening / closing of the toilet lid, a toilet lid driving unit that opens / closes the toilet lid, and a bowl that receives cleaning instructions for the toilet bowl body. A toilet seat device including a cleaning instruction means, a timing unit, and a toilet seat side control unit, which is attached to the toilet bowl body, and the toilet lid is opened when a cleaning instruction is given by the bowl cleaning instruction means. Then, before the cleaning instruction is output to the toilet body, the toilet lid driving unit starts the closing operation of the toilet lid, while if the toilet lid is closed, the cleaning instruction is given to the toilet body. The toilet seat side control unit is configured to output, and if the toilet lid is open when the toilet seat side control unit receives the cleaning instruction, it activates a timer for a predetermined time, and the toilet seat side control unit activates the timer for a predetermined time before the predetermined time elapses. When the closing of the toilet lid is detected, a cleaning instruction is output to the toilet bowl body at that timing, while when the closing of the toilet bowl is not detected after the lapse of the predetermined time, the toilet bowl main body is output at that timing. It is characterized by outputting a cleaning instruction to the toilet.

The other toilet seat device of the present invention receives a cleaning instruction for the toilet seat, the toilet lid, the toilet lid opening / closing detection unit for detecting the opening / closing of the toilet lid, the toilet lid driving unit for opening / closing the toilet lid, and the toilet bowl body. A toilet seat device including a bowl cleaning instruction means, a timing unit, and a toilet seat side control unit, which is attached to the toilet body, and the toilet lid opens when a cleaning instruction is given by the bowl cleaning instruction means.

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, a timekeeping unit 6, and a control unit 5. Here, the cleaning instruction means may be a cleaning operation by the user or an automatic cleaning instruction means based on the operation of the user, and the details will be described later.

If the toilet lid 20 is open when the toilet lid 20 is instructed by the cleaning instruction means, the toilet bowl device 1 starts the closing operation of the toilet lid 20 by the toilet lid driving unit 22 before cleaning by the toilet bowl cleaning unit 13. On the other hand, if the toilet lid 20 is closed, the toilet bowl cleaning unit 13 is configured to perform cleaning.
There are multiple modes of basic operation.

In the embodiment illustrated in FIGS. 3 and 4, the control unit 5 activates the timer for a predetermined time if the toilet lid 20 is open when the cleaning instruction is received, and the toilet lid before the predetermined time elapses. When the closure of 20 is detected, the toilet bowl cleaning unit 13 is started to wash at that timing. If the control unit 5 does not detect the closing of the toilet lid 20 after a predetermined time has elapsed, the control unit 5 causes the toilet bowl cleaning unit 13 to start cleaning at that timing (when the predetermined time has elapsed).

Further, in the embodiment illustrated in FIG. 5, if the toilet lid 20 is open when the cleaning instruction is received, the control unit 5 activates the timer for a predetermined time and starts cleaning the toilet bowl cleaning unit 13 after the predetermined time has elapsed. Let me.

By executing any of the above operations, even if the closing operation of the toilet lid 20 when the cleaning instruction is given is not completed for some reason (the toilet lid 20 does not close), after that, the bowl 12 can be closed without any problem. Cleaning is done.
Next, the detailed configuration, structure, and basic operation of the toilet bowl device 1 will be described.

1 to 5 are explanatory views of the toilet bowl device 1. As described above, FIGS. 3 and 4 are explanatory views of one operation mode, and FIG. 5 is an explanatory diagram of another operation mode. It should be noted that FIGS. 2 (a) and 2 (b) are schematic side views schematically showing the inside of the toilet bowl device 1 showing two forms in which the cleaning methods (structures) are different, and whichever method is used. You may.

The toilet device 1 is a sitting type Western-style toilet device fixed to a floor, a wall, or the like in a toilet space. The main body 10 of the toilet bowl device 1 is designed so that the bowl 12 opened upward is surrounded by the skirt portion 11, and the upper side of the bowl 12 is freely laid down with respect to the opening surface of the bowl 12. It is provided with a toilet seat 24 and a toilet lid 20 having the same rotation axis.

In the internal space of the skirt portion 11, a toilet bowl cleaning portion 13 for draining the sewage in the bowl 12 and supplying washing water into the bowl 12 from the water supply port 14 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 14, the wash water supply path 15 that supplies the wash water supplied from the water pipe (not shown) into the bowl 12 through the water supply port 14, and the wash water supply path 15. It is provided with a water supply valve 16 that supplies or shuts off the water supply to the bowl 12.

The drainage mechanism shown in FIG. 2A has a cylindrical bent trap 17 connected so as to extend rearward from the bottom of the bowl 12, the trap 17 extending further downward and connecting to the drainage port 18. Has been done. Examples of this type of drainage mechanism include a siphon type, a siphon zet type, and a siphon vortex type, which are considered to be a mechanism in which a drainage state or a sealed state is formed by a siphon action.

Further, the drainage mechanism may have a structure having a movable trap 17A as shown in FIG. 2 (b). The trap 17A is rotated in the direction of an arrow by a driving unit (not shown) to form a drainage state or a water sealing state. The trap 17A in the illustrated example is in the position in the sealed state, and in the drainage state, the trap 17A rotates so that the open end of the trap 17A faces the drain port 18. The trap 17A is surrounded by a trap case (not shown) so that sewage and odor do not leak to the outside.

Further, a drainage mechanism that is neither a siphon type nor a movable type, for example, a wash-off type drainage mechanism can be applied to the toilet bowl device 1.

Further, in the figure, an example is shown in which the toilet bowl device 1 is a tankless type directly connected to the water supply without a water washing tank (low tank), but a water washing tank may be provided.

Further, as described above, as described above, the toilet device 1 includes a toilet lid opening / closing detection unit 21 and a toilet lid driving unit 22, and further gives an opening / closing instruction from the user to the toilet lid driving unit 22. It is provided with a toilet lid operation unit 23 for receiving. Further, the toilet device 1 includes a toilet seat 24, a toilet seat open / close detection unit 25 that detects the opening / closing of the toilet seat 24, a toilet seat drive unit 26 that opens / closes the toilet seat 24, and a toilet seat operation unit 27 that receives an opening / closing instruction to the toilet seat drive unit 26. In addition, a seating detection unit 28 is also provided.

As the seating detection unit 28, for example, a load sensor for detecting seating / leaving, an infrared sensor for detecting seating / leaving from the vicinity of the rotation shaft portion of the toilet seat 24, and the like, which are built in the toilet seat 24, are adopted. As the toilet lid open / close detection unit 21 and the toilet seat open / close detection unit 25, those configured to detect the open / closed state by the opening angle are adopted.

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 (tilts) the toilet lid 20 when there is an instruction from the toilet lid operation unit 23, and the toilet seat drive unit 26 receives an instruction from the toilet seat operation unit 27. The toilet seat 24 is electrically opened and closed (tilted).

In the present specification, in both the toilet lid 20 and the toilet seat 24, the state in which the toilet lid 20 and the toilet seat 24 are upright is referred to as an open state, and a state in which the toilet lid 20 is tilted substantially horizontally and is substantially parallel to the opening surface of the bowl 12 is referred to as an open state. It is called a closed state.

In this toilet device 1, if both the toilet lid 20 and the toilet seat 24 are in the open state when the toilet lid 20 is instructed to close by the toilet lid operation unit 23 or the like, the toilet seat 24 first closes and closes. After (stopping in the closed state), the toilet lid 20 closes in conjunction with the closing operation of the toilet seat 24. If both the toilet seat 24 and the toilet lid 20 are in the closed state when the toilet seat operation unit 27 or the like instructs to open the toilet seat 24, the toilet lid 20 first opens and then opens (in the open state). After the stop), the toilet seat 24 opens so as to be linked to the opening operation of the toilet lid 20.

The toilet device 1 may be further provided with various functional devices such as a deodorizing device for deodorizing the inside of the bowl 12, a heating device for heating the toilet seat 24, and a local cleaning device for locally cleaning the toilet seat 24.

Further, the toilet device 1 includes a cleaning operation unit 29. 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.

It is desirable that the cleaning operation unit 29 is arranged in either the main body operation unit (not shown) or the remote controller (not shown). These are also provided with operation switches and operation buttons that allow various operations and settings. As the remote controller, an infrared communication remote controller is preferably used. Needless to say, the remote controller is provided with a transmitting unit (not shown), and the main body 10 is provided with a receiving unit (not shown).

The operation of the cleaning operation unit 29 acts as a cleaning instruction means, and further, the state change from sitting to leaving the seat detected by the seating detection unit 28 also acts as a cleaning instruction means. That is, when a person stands up from the toilet seat 24 while sitting, automatic cleaning is performed instead of operating the cleaning button.

Further, the cleaning instruction may be output by 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 controls the above-mentioned control targets (water supply valve 16 of the toilet cleaning unit 13, toilet lid drive unit 22, toilet seat drive unit 26, etc.), while the cleaning operation unit 29, toilet lid open / close detection unit 21, and toilet seat open / close detection are detected. A control unit 5 that receives an output signal such as a unit 25 and a seating detection unit 28 is provided. 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 and a power supply unit (not shown).

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 or guidance by sound or voice synthesis. The notification unit 7 may be configured to include a display such as an LED in place of or in addition to the sound output unit.

Next, the basic operation of the toilet bowl device 1 will be described with reference to the flowcharts of FIGS. 3 to 5. All of these operations are operations by the control unit 5 when a cleaning instruction is given by the cleaning instruction means.

The toilet device 1 may have an operation configuration in which any of the operations of FIGS. 3 to 5 is executed when a cleaning instruction is given, but the toilet device 1 is configured to execute any of the operations. It may be possible to change it in the settings. Further, if the cleaning operation unit 29 gives a cleaning instruction while the toilet device 1 is seated, the toilet device 1 does not accept the cleaning instruction.

In the following operation description, the detection of the open / closed state of the toilet lid 20 and the detection of the open / closed state of the toilet seat 24 are performed by each detection unit, but the description of the operation of those detection units will be omitted. Further, although the opening / closing operation of the toilet lid 20 and the opening / closing operation of the toilet seat 24 are performed by each drive unit, the description of the operation of those drive units will be omitted.

First, the operation of FIG. 3 will be described with reference to the flowcharts shown in steps S100 to S113. 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 by the cleaning instruction means, the notification unit 7 first notifies the cleaning instruction by, for example, an electronic sound "pip" (S100). Then, 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, S111 of S101).

Although not shown in FIG. 3, the toilet lid 20 opens after the cleaning of S111 is completed, and after a certain period of time from the open state, the opened toilet lid 20 closes and closes. It may be in a standby 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 person is no longer detected by the motion sensor. 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 lid 20 is in the open state when the cleaning instruction is received, the timer for a predetermined time is activated (Y, S102 in S101). This timer is for forcibly starting cleaning in a timely manner when the toilet seat and 24 toilet lid 20 are not closed as a result within a predetermined time in the subsequent closing operation of the toilet seat 24 and the toilet lid 20. be.

The toilet seat 24 is also electrically opened and closed in the toilet device 1. Therefore, if the toilet seat 24 is opened by the closing command of the toilet lid 20 according to the cleaning instruction, the toilet seat 24 must also be closed. Therefore, the predetermined time is the time required for both the closing operation of the toilet seat 24 and the closing operation of the toilet lid 20. It is desirable to set the time in consideration of.

After the timer is started, the state of the toilet seat 24 is determined, and if the toilet seat 24 is in the open state, the closing operation of the toilet seat 24 is started (Y in S103, S104). If the toilet seat 24 is not closed by the time the timer expires, the notification unit 7 notifies that the time has expired, and cleaning is started (N, S112, S113 of S105, S106, S105).

Since the notification at this time is of a warning level for forced cleaning, it is often a sound that can be clearly heard, such as the electronic sound "Pippi Pippi", so that the sound is not muted by the subsequent cleaning sound. It is desirable that cleaning be started after the sound is finished.

Then, if the toilet seat 24 is closed without time-up, or if the toilet seat 24 is closed at the timing of the cleaning instruction, the closing operation of the toilet lid 20 is started (N in S103, Y in S106, S107). If the toilet lid 20 is not closed by the time the timer expires, it is notified that the time has expired and cleaning is started (N, S112, S113 of S108, S109, S108).

If the toilet lid 20 is closed without time-up, the closing of the toilet lid 20 is notified by an electronic sound "pip" or the like different from that at the time of the cleaning instruction, and the bowl 12 is washed (Y, S110, S109, S109, S10). S111). It should be noted that instead of notifying that the toilet lid 20 is closed, it may be notified that cleaning is to be performed. That is, in that case, the notification is also made when the toilet lid 20 is closed (N of S101) after the cleaning instruction.

In principle, the toilet device 1 starts cleaning on condition that the toilet lid 20 is closed, but the cleaning is exceptionally performed at such a time-up (Y in S105, Y in S108). Factors that increase the time until the toilet seat 24 closes are assumed to be, for example, a failure of the toilet seat drive unit 26 and the toilet seat 24, or a case where the toilet seat 24 is stopped by hand during the closing operation. Further, as a factor of time-up until the toilet lid 20 is closed, for example, a failure of the toilet lid driving unit 22 or the toilet lid 20 or a case where the toilet lid 20 is manually stopped during the closing operation is assumed.

In such a case, when the time is up, the cleaning instruction is prioritized regardless of the state of the toilet lid 20 (toilet seat 24), and the cleaning is forcibly executed. The operation of the toilet seat 24 and the toilet lid 20 may be stopped at the will of the user, but as described above, the toilet seat 24 and the toilet can be stopped in order to encourage the user to release the restraint of the toilet seat 24 and the toilet lid 20. It is desirable to be notified (S112) in a state where the lid 20 is not closed (time is up).

Further, as an operation mode for cleaning the toilet lid 20 before closing, even if the toilet seat 24 and the toilet lid 20 are individually monitored by timers as shown in the flowcharts (S200 to S214) of FIG. good.

When a cleaning instruction is received, it is first notified by, for example, an electronic sound "pip" (S200). Then, 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, S212 of S201). Similar to the aspect of FIG. 3, the toilet lid 20 is opened after the cleaning of S212 is completed, and after a certain period of time after the opened state, the opened toilet lid 20 is closed, closed and in a standby state. (The state where the toilet lid 20 is closed) may be set.

Further, if the toilet lid 20 is in the open state when the cleaning instruction is received, the state of the toilet seat 24 is further determined, and if the toilet seat 24 is in the open state, a timer (timer # 1) for a predetermined time is activated. (Y of S201, Y of S202, S203). This timer monitors the closing operation of the toilet seat 24, and is for forcibly starting cleaning when the toilet seat 24 does not close.

After the timer is activated, the closing operation of the toilet seat 24 is started (S204). If the toilet seat 24 is not closed by the time the timer # 1 is timed up, it is notified that the time is up and cleaning is started (S205, S206, N of S205, S213, S214). As described above, as in the example of FIG. 3, in principle, the toilet device 1 starts cleaning on the condition that the toilet lid 20 is closed, but the toilet lid 20 is exceptionally such a time-up. Cleaning is done before closing (toilet seat 24).

Then, if the toilet seat 24 is closed without time-up or at the timing of the cleaning instruction, the timer (timer # 2) for a predetermined time is activated and the closing operation of the toilet lid 20 is started. (N of S202, Y of S206, S207, S208). If the toilet lid 20 is not closed by the time the timer # 2 is timed up, it is notified that the time is up and cleaning is started (N, S213, S214 of S209, S210, S209).

If the toilet lid 20 is closed without time-up, the closing of the toilet lid 20 is notified by an electronic sound "pip" or the like different from that at the time of the cleaning instruction, and the bowl 12 is washed (Y, S211 of S210, S212). It should be noted that instead of notifying that the toilet lid 20 is closed, it may be notified that cleaning is to be performed. That is, in that case, the notification is also made when the toilet lid 20 is closed (N of S201) after the cleaning instruction.

As described above, in principle, the toilet device 1 starts cleaning on the condition that the toilet lid 20 is closed, as in FIG. 3, except for such time-up (Y of S205, S209 of S205). In Y), cleaning is performed before closing the toilet lid 20.

As described above, in the operation of FIG. 4, each closing operation of the toilet seat 24 and the toilet lid 20 is individually monitored by a timer. Therefore, the closing operation is monitored at different time intervals depending on whether only the toilet lid 20 is open and the toilet seat 24 and the toilet lid 20 are both open, and the closing operation can be monitored at a more appropriate time, which is more appropriate. It can be washed at any time. For example, if only the toilet lid 20 is open (such as immediately after excretion), one of the timers (timer # 2) monitors the closing operation, but if both the toilet seat 24 and the toilet lid 20 are open. If so, the closing operation is monitored by both timers (timer # 1 + timer # 2).

As described above, in both of the embodiments of FIGS. 3 and 4, even if the closing of the toilet lid 20 (including the toilet seat 24) is not detected when the time is up, the washing is executed at the timing of the time up. Therefore, even if the toilet lid 20 is not closed due to a failure of the toilet seat 24 or the toilet lid 20 or an intermediate stop of the toilet seat 24 or the toilet lid 20 due to the user's hand or the like, there is a factor that the toilet lid 20 is not closed. It does not mean that the cleaning is not done, but the forced cleaning is done. Therefore, it is possible to prevent the state of not being washed from continuing for a long time.

In addition, according to the forced cleaning by such time-up, the cleaning is performed in the open state of the toilet lid 20, so that there is a risk of scattering of contaminants, but if the user is there, the cleaning is performed. As soon as the operation starts, the user can close the toilet lid 20 by hand, and there is almost no problem.

Further, if the closing of the toilet lid 20 is detected before the time is up, the washing is executed at the detection timing, so that it is possible to prevent the washing from being delayed more than necessary by the timer.

Next, the operation of FIG. 5 will be described with reference to the flowcharts (S300 to S314).

When a cleaning instruction is received, it is first notified by, for example, an electronic sound "pip" (S300). Then, 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, S312 of S301).

Similar to the example of FIG. 3, the toilet lid 20 is opened after the cleaning is completed, and after a certain period of time from the opened state, the opened toilet lid 20 is closed, closed and in a standby state ( The toilet lid 20 may be closed).

If the toilet lid 20 is in the open state when the cleaning instruction is received, the timer for a predetermined time is activated (Y, S302 in S301). This timer is for forcibly starting washing when the toilet lid 20 is not closed as a result within a predetermined time in the subsequent closing operation of the toilet lid 20.

After the timer is started, the state of the toilet seat 24 is determined, and if the toilet seat 24 is in the open state, the closing operation of the toilet seat 24 is started (S303, S304). If the toilet seat 24 is not closed by the time the timer expires, it is notified that the time has expired and cleaning is started (S305, S306, S305 N, S313, S314).

Then, if the toilet seat 24 is closed without time-up, or if the toilet seat 24 is closed at the timing of the cleaning instruction, the closing operation of the toilet lid 20 is started (N of S303, Y of S306, S307). Further, if the toilet lid 20 is not closed by the time the timer expires, it is notified that the time has expired and cleaning is started (S308, S309, N of S308, S313, S314).

If the toilet lid 20 is closed without the time being up, the closing of the toilet lid 20 is notified by an electronic sound "pip" or the like different from that at the time of the washing instruction, and the bowl 12 is washed (the bowl 12 is washed). Y, S311 and S312 of S310). It should be noted that the notification may be made immediately after the toilet lid 20 is closed, instead of the notification after the time is up.

As described above, as in FIG. 3, in principle, the cleaning is started on the condition that the toilet lid 20 is closed, but the cleaning is exceptionally performed with such a time-up (Y in S305, Y in S308). Will be done.

In the operation mode of FIG. 5, even if the closing operation of the toilet lid 20 is completed within a predetermined time, the cleaning is not performed until the time is up, and the cleaning is started at the timing when the time is up (Y of S310). , S311 and S312), which are different from the operation modes of FIGS. 3 and 4. That is, in the operation mode of FIG. 5, cleaning is started only at the timing of the timer time-up (N, S312 of S301) unless the cleaning instruction is given when the toilet lid 20 is in the closed state.

In this way, if the timer is activated, the cleaning is not started regardless of the time-up in any case, so that the cleaning start timing can be created by a simpler process. Therefore, it is not necessary to use the processing logic as shown in FIG. 5, and it is sufficient to forcibly start cleaning by interruptive processing due to time-up, and programming can be performed more easily.

In addition, in the case of the operation mode of cleaning when the time is up, the configuration may be such that two timers are used as in the case of the one shown in FIG.

In the operation mode shown in FIGS. 3 to 5, when the cleaning operation unit 29 gives a cleaning instruction during sitting, the cleaning instruction is not accepted, but the operation is performed when the user is seated. It may be an embodiment. In that case, the toilet lid 20 is not closed.

When cleaning while sitting, the operation may be the same as the operation when the toilet lid 20 is closed (N, S111 in S101 of FIG. 1), but the operation may be performed after a predetermined time. .. That is, in this case, the closing operation of the toilet lid 20 hits the seated body, the closing operation of the toilet lid 20 is stopped, and the cleaning is started by the time-up of the timer (S108, S112, S113 in FIG. 1). Similarly).
