A control unit 5 that receives an output signal such as a toilet seat open / close detection unit 23 is provided. The control unit 5 includes a processor such as a CPU and an MPU and various programs. The Western-style toilet device 1 naturally includes a power supply unit (not shown).

Next, the basic operation of the Western-style toilet device 1 will be described with reference to the flowcharts of FIGS. 2 to 4. FIG. 2 shows each operation triggered by a stool cleaning instruction by the operation unit 26 (stool cleaning operation unit 26a), and FIG. 3 shows each operation triggered by a urine cleaning instruction by the operation unit 26 (urine cleaning operation unit 26b). It is a flowchart. Further, FIG. 4 is an operation flowchart of a cleaning instruction for stool in a modified example of the Western-style toilet device 1.

At the timing when the cleaning instruction for stool is given, the control unit 5 inputs the open / closed state detected by the toilet lid open / close detection unit 24, and when the state is closed, the toilet bowl cleaning unit 13 is set to start cleaning. It is controlled (S100 to S102 in FIG. 2). That is, the bowl 12 is washed with its opening covered with the toilet lid 21.

Further, when the toilet lid 21 is open / closed, the control unit 5 controls the toilet bowl cleaning unit 13 to start cleaning on condition that the state detected by the seating detection unit 22 is seating (FIG. FIG. 2 S101 N, S103 Y, S104). The control unit 5 then waits until the seating detection unit 22 detects a state change from the seated state to the unoccupied state, and after a predetermined time has elapsed from the detection of the state change, the toilet lid driving unit 25 is closed so as to close the toilet lid 21. Control (S105 to S107). That is, in this case, the bowl 12 is washed while the user is seated on the toilet seat 20 or, if the user leaves the seat in the middle, the opening is covered with the toilet lid 21. After that, when the user leaves the seat, the toilet lid 21 is automatically closed.

When the toilet lid 21 is open, not seated, and the open / closed state detected by the toilet seat open / close detection unit 23 is open, the control unit 5 controls the toilet bowl cleaning unit 13 to start cleaning (FIG. 2). S101 N, S103 N, S108 Y, S109). That is, in this case, the bowl 12 is washed with both the toilet lid 21 and the toilet seat 20 open.

Further, when the toilet lid 21 is open, not seated, and the toilet seat 20 is closed, the following operation is executed. That is, in that case, the control unit 5 is notified by the notification unit 27 as a warning that the toilet seat 20 is closed but not seated and the toilet lid 21 is open and a cleaning instruction for stool is given. It is controlled (N in S101, N in S103, N in S108, S110 in FIG. 2). After that, the control unit 5 waits until the toilet lid open / close detection unit 24 detects a state change from the open state to the closed state of the toilet lid 21, and controls the toilet bowl cleaning unit 13 so that cleaning is started at the timing of the state change. (S111 and S112 in FIG. 2). That is, in this case, the bowl 12 is not washed, but is washed when the toilet lid 21 changes to the closed state.

Thus, at the timing when the stool cleaning operation is performed, when the toilet lid 21 is closed, when a person is seated on the toilet seat 20 even when the toilet lid 21 is open, or when the toilet lid 21, the toilet seat 20 When both are open, washing of the bowl 12 is started.

On the other hand, when the toilet lid 21 is in the open state and the toilet seat 20 is in the closed state even though it is not seated, the cleaning of the bowl 12 is not started at that timing even if a cleaning instruction is given. Even if the washing is not started because the toilet lid 21 is in the open state as described above, the washing of the bowl 12 is started when the toilet lid 21 is subsequently changed from the open state to the closed state.

As described above, in the Western-style toilet device 1, the bowl 12 is washed with the opening of the bowl 12 closed, with the closing of the toilet lid 21 as the starting condition for the cleaning for stool. .. Therefore, the pollutants contained in the excrement (stool) are suppressed from being scattered to the outside of the bowl 12.

Further, as described above, in the Western-style toilet device 1, the toilet bowl (bowl 12) is washed at the timing of operation even when the toilet lid 21 is in the open state, as an exception in the following pattern.
(1) When the toilet lid 21 is open and seated (2) When the toilet lid 21 is open and the toilet seat 20 is open (of course, not seated)

In (1), since the buttocks of a person replace the toilet lid 21, it is possible to suppress the scattering of pollutants to the outside even if the toilet lid 21 is not closed. Moreover, if the user leaves the seat during cleaning, the toilet lid 21 closes, so that the scattering of pollutants is suppressed in this case as well. Further, in that case, the toilet lid 21 is not closed immediately, but the timer is set to wait for the patient to leave the seat before closing the toilet lid 21, so that the toilet lid 21 to be closed collides with a person. Can be prevented. That is, the user does not have to rush to stand up after operating the cleaning instruction.

In (2), the toilet lid 21 is open and the toilet seat 20 is open to enable cleaning for stool. That is, it is convenient because when a boy uses it for standing urine in such a state and a cleaning instruction for stool is given, the cleaning is performed immediately. Further, since the toilet lid 21 does not close even when a cleaning instruction for stool is given after cleaning the bowl 12, the cleaning state can be visually recognized without being disturbed by the toilet lid 21. As described above, unlike the toilet bowl device that closes the toilet lid 21 immediately after receiving a cleaning instruction for stool, it is excellent in convenience.

As described above, since the Western-style toilet device 1 is allowed to perform an exceptional cleaning operation when the toilet lid 21 is open, the toilet lid 21 must be closed or the toilet lid 21 must be closed according to the cleaning instruction. It is more convenient than those that cannot wash the toilet bowl.

Further, even if the cleaning is not started when the toilet lid 21 is open (N in S108 in FIG. 2) when the cleaning instruction is given, the cleaning is started when the user closes the toilet lid 21. It is convenient because there is no need to perform a cleaning operation again. Moreover, since the cleaning is performed after the toilet lid 21 is closed, the scattering of pollutants can be suppressed in this case as well.

In the Western-style toilet device 1 of the present embodiment, exceptional cleaning by opening the toilet lid 21 is permitted in relation to seating and opening of the toilet seat 20, but the toilet bowl must be opened if the toilet lid 21 is opened. It may be a device in which the cleaning is not performed. That is, the device may not include the seating detection unit 22 and the toilet seat opening / closing detection unit 23.

Further, as shown in S200 and S201 of FIG. 3, at the timing when the cleaning instruction for urine is given, the control unit 5 starts the cleaning to supply the cleaning water for urine to the bowl 12, and the toilet bowl cleaning unit 13 To control. That is, when there is a cleaning instruction for urine, cleaning is performed regardless of the open / closed state of the toilet lid 21.

With such an operation configuration, the toilet bowl can be cleaned even when the toilet lid 21 is opened for cleaning urine. Since the urine itself does not contain much pollutants, it is more convenient not to make the closing of the stool lid 21 an exceptional activation condition when instructing cleaning for urine.

Next, with respect to the modified example of the Western-style toilet device 1 shown in FIG. 1, another example of the operation triggered by the cleaning instruction for stool will be described based on the flowchart of FIG. Since the configuration of the Western-style toilet device 1 is the same as that of FIG. 1, the illustration and description of the basic configuration will be omitted. Specifically, in the one of FIG. 1, it is only necessary to change the operation by the control unit 5. For example, in the same Western-style toilet device 1, it may be possible to switch which of the operations shown in FIGS. 2 and 4 is performed.

In this Western-style toilet device 1, the operation when the toilet lid 21 is open and seated is different from that in FIG. That is, when the toilet lid 21 is seated in the open state (N in S301 and Y in S303 in FIG. 4) when a cleaning instruction for stool is given, the operations S304 to S308 in FIG. 4 are executed. It differs from the operation of FIG. 2 in that.

That is, in that case, the timer for a predetermined time is started at the same time as the cleaning is started (S304, S305 in FIG. 4). If abandonment is detected before the timer expires, a voice-synthesized warning such as "Please do not stand up until cleaning is complete" or "Please close the toilet lid immediately" is output. (S306 to S308 in FIG. 4). Further, if the leaving is not detected until the time is up, that is, when the time is up (Y in S306), the process ends without a warning being output.

As a result, in the Western-style toilet device 1 of FIG. 4, the toilet bowl is exceptionally washed while sitting, as in the case of FIG. However, if a detachment is detected during washing, the user is prompted to continue sitting or to close the toilet lid 21 by notification, so that the user follows the instructions and the opening of the bowl 12 is continuously covered. There is a high possibility that it will be done. Therefore, in this case as well, the scattering of pollutants can be suppressed as in the case of FIG. Of course, in this case as well, the washing can be performed while sitting, which is highly convenient for the user.

In the Western-style toilet device 1 of FIG. 1, the toilet seat 20 and the toilet lid 21 may be interchangeable as a unit. In particular, the Western-style toilet device 3 to which the toilet seat device 30 as shown in FIG. 5 is retrofitted (or replaced) may be used.

Further, the Western-style toilet device 3 has parts equivalent to the toilet seat 20, the seating detection unit 22, the toilet seat opening / closing detection unit 23, the toilet lid 21, the toilet lid opening / closing detection unit 24, and the toilet lid drive unit 25 in FIG. The configuration may be replaced with the toilet seat device 30, but other configurations may be used as shown in FIG.

The Western-style toilet seat device 3 of FIG. 5 is further provided with a bowl cleaning operation unit 38, and is configured to be able to output a cleaning instruction of the bowl 12 to the toilet bowl cleaning unit 13 from the toilet seat device 30 side. Specifically, the toilet seat device 30 includes a toilet seat side control unit 31, and when a bowl cleaning operation unit 38 gives a cleaning instruction, the toilet seat side control unit 31 receives this and passes through the control unit 5 on the main body side. , The toilet bowl cleaning unit 13 can be controlled to clean the bowl 12. Further, the toilet seat side control unit 31 may directly control the toilet bowl cleaning unit 13.

As shown in FIG. 5, the Western-style toilet device 3 is configured to include not only the bowl cleaning operation unit 38 on the toilet seat device 30 side but also the operation unit 26 on the main body side. That is, the one in FIG. 5 has a configuration in which a cleaning instruction can be given by either the operation unit 26 or the bowl cleaning operation unit 38. Further, the bowl cleaning operation unit 38 may be used only for the cleaning instruction without providing the operation unit 26 (cleaning operation unit 26a, 26b) on the main body side.

The Western-style toilet device 3 is also capable of the operations shown in FIGS. 2 and 3 as in the case of FIG. 1, and can also be operated as shown in FIG.

As a result, the toilet bowl cleaning unit 13 supplies the urine cleaning water to the 12 bowls when the operation unit 26 instructs to clean the urine. On the other hand, when the operation unit 26 gives an instruction to clean the stool, the toilet bowl cleaning unit 13 uses the stool cleaning water when the toilet lid open / close detection unit 36 determines that the toilet lid 33 is in the closed state. Supply to bowl 12.
