Description

Toilet fittings and toilet seat fittings

The present invention relates to a toilet device having a toilet lid and a toilet lid driving part, and a toilet seat device having a toilet lid and a toilet lid driving part used while being attached to a toilet body.

In recent years, based on the viewpoint of preventing the spread of pollutants contained in excrement when flushing the toilet (bowl), it is encouraged to flush the bowl with the toilet lid closed after excretion, so that the contents are excreted into the bucket. The droplets of pollutants contained in the feces of the body will not scatter to the outside of the toilet.

In order to surely perform flushing of the body of the toilet in the closed state of the toilet lid, a toilet device has been proposed. When there is a flushing instruction, the toilet lid is first electrically closed by the toilet lid driving part, and then the toilet lid is closed. The barrel is flushed (for example, refer to Patent Document 1). [Previously known technical literature] [Patent Literature]

[Problems to be Solved by Invention]

However, such an electrically opened and closed toilet lid should originally be closed by the flushing instruction as a trigger, but sometimes due to various factors, it cannot be moved from the beginning or on the way. In this case, if you follow the sequence of flushing after closing the toilet lid, of course, the subsequent flushing of the tub body will be delayed.

For example, when there is an obstacle in front of the raised toilet lid, or when the toilet lid drive unit or the toilet lid fails, the toilet lid cannot be brought into the closed state. As for the obstacle, for example, in order to confirm the flushing state of the excrement, after issuing a flushing instruction by a key operation or the like, the user himself can stop the toilet lid which is about to be closed by hand. It is inappropriate to prevent the closing action of the toilet lid due to obstacles (human hands, etc.) like this, resulting in the delay in flushing the body of the toilet.

[Effect of invention]

Since the toilet device and the toilet seat device of the present invention are configured as described above, the body can be flushed even if the closing action of the toilet lid based on the flush instruction cannot be properly performed.

Embodiments of the present invention will be described below with reference to the accompanying drawings. In the toilet devices 1 and 3 described below, in principle, the body 12 is flushed with the toilet lid 20 closed from the viewpoint of preventing the spread of pollutants contained in the excrement. Therefore, the normal action will be: when there is a flushing instruction, if the toilet lids 20 and 40 are not closed, in order to make the toilet lids 20 and 40 into the closed state, the toilet lids 20 and 40 will be automatically electrically operated before flushing. closing action.

First, the outline of the toilet device 1 of this embodiment will be described below. This toilet device 1 is a device having a configuration as illustrated in FIGS. 1 and 2 , and can be executed by selecting one of the basic operations of a plurality of aspects shown in FIGS. 3 to 5 .

The toilet device 1 includes: a body 12, a toilet flushing part 13 for supplying flushing water to the body 12 to flush the body 12, a toilet lid 20, a toilet lid opening and closing detection part 21 for detecting the opening and closing of the toilet lid 20, and a toilet lid drive unit 22 for opening and closing the toilet lid 20 . Furthermore, the toilet device 1 of the present invention includes flushing instruction means for outputting a flushing instruction to the toilet flushing unit 13 , a timer unit 6 , and a control unit 5 . Here, the flushing instructing means is divided into a flushing operator from the user and a flushing operator based on the user's actions, the details of which will be described later.

The toilet device 1 of the present invention is configured such that when there is a flushing instruction from the flushing instruction means, when the toilet lid 20 is opened, the toilet lid driving unit 22 starts closing the toilet lid 20 before flushing with the toilet flushing unit 13. On the other hand, when the toilet lid 20 is closed, the toilet flushing unit 13 performs flushing. As far as the basic action is concerned, there are several forms.

3 and 4 , when the control unit 5 receives the flushing instruction, if the toilet lid 20 is open, it starts a timer for a predetermined time, and before the predetermined time elapses, it detects that the toilet lid 20 has been closed. When it is closed, the toilet flushing part 13 is started flushing at that time. Furthermore, when the predetermined time has elapsed and the control unit 5 has not detected that the toilet lid 20 is closed, the control unit 5 starts flushing the toilet flushing unit 13 at that time (when the predetermined time has elapsed).

5, when the control unit 5 receives the flushing instruction, if the toilet lid 20 is opened, it starts a timer for a predetermined time, and when the predetermined time elapses, the toilet flushing unit 13 is activated. Start rinsing.

By performing one of the above actions, even if there is a flushing instruction, the closing action of the toilet lid 20 cannot be completed for some reason (the toilet lid 20 will not be closed), and there will be no problem afterwards. The barrel body 12 is flushed on the ground. Next, the detailed configuration, structure, and basic operation of the toilet device 1 will be described.

1 to 5 are explanatory diagrams of the toilet device 1 . As described above, FIG. 3 and FIG. 4 are explanatory diagrams of one mode of operation, and FIG. 5 is an explanatory diagram of another mode of operation. 2( a ) and ( b ) are schematic side views of the interior of the toilet device 1 having two different flushing methods (structures), and any method may be adopted.

The toilet device 1 is a Western-style sitting toilet device fixed to the floor or wall in the toilet space. The main body 10 of the toilet device 1 has a barrel body 12 that opens upward and is surrounded by a side edge 11; , and they are the toilet seat 24 and the toilet cover 20 with the same rotation axis.

In the inner space of the side edge portion 11 , a toilet flushing portion 13 is arranged, which discharges the sewage in the barrel 12 and supplies flushing water into the barrel 12 from the water inlet 14 to flush the barrel 12 . The toilet flushing part 13 has a water inlet mechanism and a drainage mechanism.

The water inlet mechanism includes: a water inlet 14, a flushing water supply pipeline 15, and a water inlet valve 16; The supply of flushing water; the water inlet valve 16 is arranged in the middle of the flushing water supply pipeline 15 to supply or cut off the water inlet to the barrel 12 .

The drainage mechanism shown in FIG. 2( a ) has a cylindrical curved water trap 17 connected to extend backward from the bottom of the barrel 12 , and the water trap 17 extends further downward and is connected to Drain 18. As such a drainage mechanism, there are siphon type, siphon jet type, vortex siphon type, etc., which form a drainage state or a water sealing state by siphon action.

Furthermore, as a drainage mechanism, as shown in FIG.2(b), you may have the structure of the movable water trap 17A. The water trap 17A is rotated in the direction of the arrow by a driving part (not shown) to form a drain state or a water seal state. The water trap 17A in the illustrated example is located in the water-sealing state. In the drainage state, the open end of the water trap 17A will perform a rotating motion toward the drain port 18 . In addition, the trap 17A is surrounded by a trap casing (not shown) so that sewage and odors do not leak to the outside.

Furthermore, in the toilet device 1, a drainage mechanism that is neither a siphon type nor a movable type, for example, a flushing type drainage mechanism can also be applied.

Furthermore, in the illustration, the toilet device 1 is shown as an example of a direct-flushing type without a water tank without a water tank (low tank), but it may also be a configuration with a water tank.

Furthermore, as described above, the toilet device 1 is provided with a toilet lid opening/closing detection part 21 and a toilet lid driving part 22 as described above, and also has a toilet lid operating part 23 to receive the user The opening and closing instruction to the toilet lid drive unit 22. Furthermore, the toilet device 1 includes a toilet seat 24 , a toilet seat opening and closing detection unit 25 for detecting the opening and closing of the toilet seat 24 , a toilet seat driving unit 26 for opening and closing the toilet seat 24 , and accepting the opening and closing of the toilet seat driving unit 26 . The toilet seat operation part 27 instructed is further provided with a seating detection part 28 .

As the seating detection unit 28 , for example, a load sensor built into the toilet seat 24 to detect seating/disengagement, or an infrared sensor for detecting seating/disengagement from the vicinity of the rotating shaft portion of the toilet seat 24 is used. tester, etc. As the toilet lid opening/closing detecting unit 21 and the toilet seat opening/closing detecting unit 25, those configured to detect the opening/closing state by the opening angle are used.

The toilet lid drive unit 22 and the toilet seat drive unit 26 are each constituted by a motor or the like. The toilet lid driving unit 22 electrically opens and closes the toilet lid 20 (to stand or lie down) when there is an instruction from the toilet lid operating unit 23, etc.; and the toilet seat driving unit 26 operates the toilet seat when there is an instruction from the toilet seat operating unit 23. The toilet seat 24 is electrically opened and closed (to stand up or to lie down) when it is instructed by the section 27, etc.

Moreover, in this specification, whether it is for the toilet lid 20 or the toilet seat 24, the state of standing up substantially vertically is called the open state; The roughly parallel state is called the closed state.

In the toilet device 1, when there is an instruction for the closing action of the toilet cover 20 through the toilet cover operating portion 23 and the like, if the toilet cover 20 and the toilet seat 24 are both open, the toilet seat 24 will first close the operation. After being closed (still in the closed state), the toilet lid 20 will perform the closing action as if it is linked to the closing action of the toilet seat 24 . Furthermore, when there is an instruction to open the toilet seat 24 through the toilet seat operating portion 27 and the like, if the toilet seat 24 and the toilet lid 20 are both closed, the toilet lid 20 will first perform the opening action; After being opened (still in the open state), the toilet seat 24 will perform the opening action as if it is linked to the opening action of the toilet lid 20 .

The toilet device 1 may be further configured to include various functional devices such as a deodorizing device for deodorizing the body 12 , a heating device for heating the toilet seat 24 , and a local flushing device for flushing a local area.

Furthermore, the toilet apparatus 1 is provided with the flushing operation part 29 . The flushing operation unit 29 includes a flushing button 29a for stool and a flushing button 29b for urination, and outputs a flushing instruction to the toilet flushing unit 13 via the control unit 5 described later.

In addition, the flushing operation part 29 is preferably arranged on both the main body operation part (not shown) and the remote control (not shown). In these two places, there are also provided operation switches, operation buttons, and the like that can perform various operations or settings. As the remote control, it is better to use the infrared communication model. The remote controller is provided with a transmitting part (not shown), and the main body 10 is provided with a receiving part (not shown), which need not be repeated.

Although the operation of the flushing operation part 29 will serve as the flushing instruction means, furthermore, the state change from sitting to leaving the seat detected by the seating detection part 28 will also serve as the flushing indicating means. effect. That is to say, when the person is seated, when the person gets up from the toilet seat 24, the flush button operation is replaced by automatic flushing.

Furthermore, it is also possible to configure a configuration in which both the flushing button 29a for stool and the flushing button 29b for urination are not provided, and a flushing instruction is outputted by one flushing button. That is, in this case, as the amount of flushing water sent to the barrel 12 , there is no distinction between large-capacity for stool and small-capacity for urination, and there is only one type of large-capacity for stool.

The toilet device 1 includes a control unit 5 , which controls the above-mentioned control objects (the water inlet valve 16 of the toilet flushing unit 13 , the toilet lid driving unit 22 , the toilet seat driving unit 26 , etc.) on the one hand, and receives the flushing operation unit 29 on the other hand. , and the output signals of the toilet lid opening and closing detection part 21 , the toilet seat opening and closing detection part 25 , and the seating detection part 28 , etc. The control unit 5 includes a processor such as a CPU (Central Processing Unit) or an MPU (Microprocessor), and various programs. The toilet device 1 further includes a timer unit 6 and a power supply unit (not shown).

Furthermore, the toilet device 1 is provided with a notification unit 7 composed of a speaker or the like, and uses sound effect or voice synthesis to notify the abnormality, state, and guidance of the device. In addition, the notification unit 7 may be configured as a display including an LED or the like instead of or in addition to the sound effect output.

Next, the basic operation of the toilet device 1 will be described based on the flowcharts of FIGS. 3 to 5 . These operations are all operations performed by the control unit 5 when there is a flushing instruction from the flushing instruction means.

The toilet device 1 may be configured to perform one of the actions shown in FIGS. 3 to 5 when there is a flushing instruction, but the toilet device 1 may be changed to perform one of the actions. In addition, the toilet apparatus 1 of the present invention does not accept the flushing instruction from the flushing operation unit 29 when the flushing instruction is given while seated.

In the following description of the operation, each detection part detects the opening and closing state of the toilet lid 20 or detects the opening and closing state of the toilet seat 24, but the description of the operation of these detection parts will be omitted. In addition, 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 part, description of the operation of these drive parts will be abbreviate|omitted.

First, the operation of FIG. 3 will be described according to the flowchart shown in steps S100 to S113. In addition, in the following description, regarding the operation steps shown in FIGS. 3 to 5 , the part that was originally described as “step S×××” will be abbreviated as “S×××” with only symbols.

When the flushing instruction from the flushing instruction means is received, the notification unit 7 firstly notifies the matter by, for example, an electronic sound "beep beep" ( S100 ). Then, the open/closed state of the toilet lid 20 is determined, and if it is in the closed state, the flushing of the bowl body 12 will be performed immediately (“No” in S101 , S111 ).

Although it is not shown in FIG. 3 , the toilet lid 20 can also be opened after the flushing in S111 ; after a certain time has passed, the toilet lid 20 in the open state will be closed. Close to enter the standby state (state in which the toilet lid 20 is closed).

The opening action of the toilet lid 20 after flushing is performed to allow the user to confirm the residual dirt in the tub body 12 after flushing. That is to say, the user does not need to manually open the toilet lid 20 in order to confirm the inside of the tub body 12 after flushing.

In addition, instead of the above-mentioned delay of the specific time, the human body sensor can be used to restore the standby state at the time point when no human is detected. Of course, the user can close the toilet lid 20 with the toilet lid operating portion 23, so it is not necessary to automatically restore the standby state.

Furthermore, if the toilet lid 20 is in the open state when the flush instruction is received, a timer for a predetermined time is started (“Yes” in S101 , S102 ). This timer is used for the subsequent closing operation of the toilet seat 24 and the toilet lid 20. If the toilet seat 24 and the toilet lid 20 are not closed within a predetermined time as a result, the flushing is periodically forced to start.

Moreover, in this toilet apparatus 1, the toilet seat 24 is also electrically opened and closed. Therefore, when the flushing instruction issues the closing command of the toilet lid 20, if the toilet seat 24 is open, the toilet seat 24 must also be closed, so the predetermined time is preferably set as the time considering the closing action of the toilet seat 24 and the toilet lid. The time required for both sides of a closing action of 20.

After the timer is started, the state of the toilet seat 24 is determined; if the toilet seat 24 is in the open state, the closing operation of the toilet seat 24 is started (“Yes” in S103 , S104 ). If the toilet seat 24 is not closed until the timer expires, the notification unit 7 reports that the time has elapsed, and flushing starts (S105, NO in S106, YES in S105, S112, S113).

Since the notification at this time is for those with a warning level for forced flushing, it is better to have electronic sounds such as "beep beep beep" that can be clearly heard; in order to prevent the subsequent flushing sound from covering up the sound effect, it is better to be in the sound effect. Start rinsing after beeping.

Next, when the toilet seat 24 is closed before the timer ends, or when the toilet seat 24 is closed at the time of the flushing instruction, the closing action of the toilet lid 20 is started (“Yes” in S106 , “No” in S103 ) , S107). If the toilet lid 20 is not closed before the timer expires, it will notify that the time has come and start flushing (S108, NO in S109, YES in S108, S112, S113).

If the toilet lid 20 is closed before the timer expires, it will notify the toilet lid 20 that the toilet lid 20 has been closed with an electronic sound “beep” different from the flushing instruction, and perform flushing of the bowl body 12 (“Yes” in S109, S110, S111). Also, instead of reporting that the toilet lid 20 is closed, it is also possible to notify that flushing is to be performed. That is, also in such a case, when the toilet lid 20 after the flush instruction is closed (NO in S101), it is notified.

In principle, the toilet apparatus 1 starts flushing on the condition that the toilet lid 20 is closed, but the flushing is performed on the basis of the completion of the timing (“Yes” in S105 , “Yes” in S108 ) as an exception. Factors that cause the timer to expire before the toilet seat 24 is closed include, for example, failure of the toilet seat driver 26 and the toilet seat 24, or the situation where the toilet seat 24 is blocked by hand during the closing operation. Furthermore, the factors that cause the timing to end before the toilet lid 20 is closed can be imagined, for example, the toilet lid driver 22 or the toilet lid 20 malfunctions, or the toilet lid 20 is blocked by hand during the closing operation.

In this case, when the timer ends, regardless of the state of the toilet lid 20 (toilet seat 24 ), the flushing instruction is given priority, and flushing is forced. Although there are cases where the toilet seat 24 and the toilet lid 20 are stopped based on the wishes of the user, in order to urge the user to release the restraint on the toilet seat 24 and the toilet lid 20, the toilet seat 24 and the toilet lid 20 are still used as described above. It is preferable to notify (S112) when the toilet lid 20 is not closed (time has come).

Furthermore, as an operation mode of flushing before the toilet lid 20 is closed, as shown in the flowchart (S200-S214) of FIG. 4, the toilet seat 24 and the toilet lid 20 may be individually monitored by a timer .

When a flushing instruction is received, firstly, it is notified by electronic sound "beep beep" or the like (S200). Then, the open/closed state of the toilet lid 20 is determined, and if it is in the closed state, the flushing of the tub body 12 will be performed immediately (“No” in S201 , S212 ). Similar to the state of FIG. 3 , the toilet lid 20 can also be opened after the flushing in S212 is completed; after a certain time has elapsed after being in the open state, the toilet lid 20 in the open state will be closed and closed. to enter the standby state (the state in which the toilet lid 20 is closed).

Furthermore, if the toilet lid 20 is in the open state when the flushing instruction is received, the state of the toilet seat 24 will be further determined; if the toilet seat 24 is in the open state, a timer for a predetermined time (timer #1) is started. ) ("Yes" in S201, "Yes" in S202, S203). The timer is used to monitor the closing action of the toilet seat 24, and when the toilet seat 24 is not closed, the user is forced to start flushing.

After the timer is started, the closing action of the toilet seat 24 is started ( S204 ). If the toilet seat 24 is not closed until the timer #1 expires, it will notify that the time has come and start flushing (S205, NO in S206, YES in S205, S213, S214). In this way, as in the example of FIG. 3 , in principle, the toilet device 1 starts flushing on the condition that the toilet lid 20 is closed, but it will be exceptionally based on the end of the timing, and the toilet seat 20 (toilet seat) will start flushing. 24) Rinse before closing.

Secondly, when the toilet seat 24 is closed before the timer expires, or when the toilet seat 24 is closed at the time indicated by the flushing instruction, a timer for a predetermined time (timer #2) will be started, and the toilet lid 20 will be closed at the same time. Closing action ("Yes" in S206, "No" in S202, S207, S208). If the toilet lid 20 is not closed before the timer #2 expires, it will notify that the time has come and start flushing (S209, "No" in S210, "Yes" in S209, S213, S214).

If the toilet lid 20 is closed before the timer expires, it will notify the toilet lid 20 that the toilet lid 20 has been closed with an electronic sound “beep” different from the flushing instruction, and perform flushing of the tub body 12 (“Yes” in S210, “Yes” in S210) S211, S212). Also, instead of reporting that the toilet lid 20 is closed, it is also possible to notify that flushing is to be performed. That is, even in such a case, it is notified when the toilet lid 20 after the flush instruction is closed (NO in S201).

In this way, the toilet device 1 is the same as in FIG. 3 , in principle, the flushing starts on the condition that the toilet lid 20 is closed, but it is exceptionally completed based on the timing (“Yes” in S205 , “Yes” in S209 ). ”), and flushes before the toilet lid 20 is closed.

In this way, the action of FIG. 4 is that the respective closing actions of the toilet seat 24 and the toilet lid 20 are individually monitored by the timer. Therefore, when only the toilet lid 20 is opened, the closing action will be monitored at a time interval different from the time interval when the toilet seat 24 and the toilet lid 20 are both open, and the closing action can be monitored at a more appropriate time. Rinse at a more appropriate time. For example, if only the toilet lid 20 is opened (immediately after excretion, etc.), one of the timers (timer #2) is used to monitor the closing action; but if the toilet seat 24 and the toilet lid 20 When both are open, both timers (timer #1 + timer #2) will monitor the closing action.

3 and 4 , even if the toilet lid 20 (including the toilet seat 24 ) has not been detected to be closed at the end of the timer, it will be at the time when the timer ends. Perform flushing. Therefore, even if the toilet seat 24 or the toilet lid 20 fails, or the toilet seat 24 or the toilet lid 20 is stopped on the way due to the user's hand or the like, the toilet lid 20 cannot be closed. It will not be forced to flush because the factors that prevent it from becoming a closed state will not cause a situation where flushing cannot be performed. Therefore, it is possible to avoid a situation in which the state of being unable to be flushed continues for a long time.

In addition, although the forced flushing based on the expiration of the timer, flushing is performed with the toilet lid 20 open, so there is a risk that pollutants will be scattered, but as long as the user is present, the flushing starts immediately by the user. It is enough to close the toilet lid 20 by hand, which is hardly a problem.

Furthermore, if it is detected that the toilet lid 20 is closed before the timer expires, flushing is performed at the detection time point, so the situation of unnecessary delay of flushing due to the timer can be avoided.

Next, the operation of FIG. 5 will be described according to the flowchart ( S300 to S314 ).

When a flushing instruction is received, firstly, it is notified by electronic sound "beep beep" or the like (S300). Then, the open/closed state of the toilet lid 20 is determined, and if it is in the closed state, the flushing of the bowl body 12 will be performed immediately (“No” in S301 , S312 ).

Similar to the example in FIG. 3 , the toilet lid 20 can also be opened after flushing; after a certain time has elapsed from being in the open state, the toilet lid 20 in the open state will be closed and closed to enter. Standby state (state in which the toilet lid 20 is closed).

Furthermore, if the toilet lid 20 is in the open state when the flush instruction is received, a timer for a predetermined time is started (YES in S301, S302). This timer is used for the subsequent closing action of the toilet lid 20, and if the toilet lid 20 is not closed within a predetermined time as a result, the flushing is forced to start.

After the timer is started, the state of the toilet seat 24 is determined; if the toilet seat 24 is in the open state, the closing action of the toilet seat 24 is started ( S303 , S304 ). If the toilet seat 24 has not been closed until the timer expires, the time has elapsed and flushing is started (S305, NO in S306, YES in S305, S313, S314).

Next, when the toilet seat 24 is closed before the timer expires, or when the toilet seat 24 is closed at the time of the flushing instruction, the closing action of the toilet lid 20 is started (“Yes” in S306 , “No” in S303 ) , S307). Furthermore, if the toilet lid 20 is still not closed before the timer expires, it will notify that the time has come and start flushing (S308, "No" in S309, "Yes" in S308, S313, S314).

If the toilet lid 20 is closed before the timer expires, and when the timer expires, an electronic sound “beep” that is different from the flushing instruction will be used to notify that the toilet lid 20 has been closed, and the bowl body 12 will be flushed (step S310 ). "Yes", S311, S312). In addition, the notification may not be made after the timer ends, but the notification may be made immediately after the toilet lid 20 is closed.

In this way, as in FIG. 3 , in principle, the flushing is started on the condition that the toilet lid 20 is closed, but it is performed based on the completion of such timing (“Yes” in S305 , “Yes” in S308 ) as an exception. rinse.

As shown in FIG. 5, even if the closing action of the toilet lid 20 is completed within a predetermined time, the flushing will not be performed until the end of the timing, and the flushing will start at the time when the timing is over (“Yes” in S310 ’ , S311 , S312 ), which is different from the actions shown in FIG. 3 and FIG. 4 . That is to say, in the action mode of FIG. 5 , unless the toilet lid 20 is in the closed state, the flushing starts only when the timer expires (“No” in S301 , S312 ).

In this way, once the timer is started, no matter what the situation is, the flushing will not be started without the completion of the timing, so that the flushing start time point can be shaped by a simpler process. In short, it is not necessary to set the processing logic as shown in FIG. 5 , and it is only necessary to force the start of flushing by processing an interrupt (interrupt) triggered by the end of the timer, and programming can be made easier.

In addition, in the case of the operation mode of flushing at the end of the timing, as shown in FIG. 4 , two timers may be used.

In the operation modes shown in FIGS. 3 to 5 , when there is a flushing instruction from the flushing operation unit 29 while seated, the flushing instruction is not accepted; The mode of the action of rinsing. In this case, the closing operation of the toilet lid 20 is not performed.

In the case of flushing while seated, the same action as the action when the toilet lid 20 is closed (No in S101 of FIG. 1 , S111 ) may be used, but it may be an action of flushing after a predetermined time. That is to say, in this case, the toilet lid 20 in the closing action collides with the seated human body to stop the closing action of the toilet lid 20, and the flushing starts according to the end of the timer (common with S108 and S112 in FIG. 1 ). , the same as S113).

3, 4, and 5 described above, as long as one of them can be executed, for example, it can be set to one of them in the setting operation part (not shown).

3 to 5 can also be applied to the situation of urination, but the situation of urination can also be excluded. For example, if the flush button 29b for urination is operated and the toilet seat 24 is in the open state, it is determined that the male is urinating in the standing position, and the flushing action may be performed without closing the toilet seat 24 and the toilet lid 20.

Furthermore, the operation structure of the toilet device 1 shown above is that the closing operation of the toilet seat 24 is completed and the closing operation of the toilet lid 20 is restarted, but the operation may be performed at the same time, or the closing operation of the toilet lid 20 may be higher than that of the toilet seat 20. The closing action of the toilet seat 24 is performed with a slight delay.

Furthermore, the toilet device 1 is not limited to the above, and the toilet seat 24 and the toilet lid 20 can be replaced in one body. In particular, as shown in FIG. 6 , it may be the toilet device 3 in which the toilet seat device 30 is installed (or replaced) afterward. The basic configuration of the toilet device 3 according to another embodiment of the present invention will be described below based on FIGS. 6( a ) and ( b ).

That is, in the example of FIG. 6 , the flushing operation unit 29 and the barrel flushing operation unit 49 are configured to issue flushing instructions. Furthermore, the flushing operation part 29 may not be provided on the toilet main body side, and the flushing instruction may be given only by the body flushing operation part 49 . Moreover, it is preferable that the flushing operation part 49 of the tub body also has a flushing button for stool and a flushing button for urination.

Although the operation of the tub body flushing operation part 49 will play the role of the tub body flushing indication means, furthermore, the state change from sitting to being out of seat detected by the sitting detection part 48 will also Play the role of the barrel flushing indicator. That is, when sitting down, when getting up from the toilet seat 44, instead of the operation of the flush button, automatic flushing is performed.

This toilet device 3 can perform the operations of FIGS. 3 to 5 and the like in the same manner as the toilet device 1 of FIG. 1 . In short, when there is a flushing instruction from the body flushing instructing means (the body flushing operation part 49 ), the toilet flushing part 13 will in principle perform the flushing of the body 12 with the toilet lid 40 closed. Although the toilet lid 40 will be closed when there is a flushing instruction, if the toilet lid 40 is in the open state, it is monitored by a timer. When the timer expires, even if the toilet lid 40 is not in the closed state, the toilet lid 40 will be flushed.
