To the storage position. The process related to cleaning the nozzle will be described below.

FIG. 7 shows the CPU 10 of the electronic control unit 100.
6 is a flowchart showing a nozzle cleaning routine executed by No. 2. This nozzle cleaning routine is started when the user presses the stop button 144.

When the processing is started, the CPU 102 first determines whether or not the user is sitting on the toilet seat 6 based on whether or not the detection signal of the seating sensor 6a is in the ON state (step S100). . Here, if it is determined that the seating sensor 6a is in the off state, the following process is executed, and if it is determined that it is in the on state, the execution of this cleaning routine is ended.

When it is determined that the seating sensor 6a is in the off state, the CPU 102 first starts a timer inside the CPU 102 (step S110), and the elapsed time T obtained by the timer is set to the first value. It is determined whether the predetermined time t1 has been exceeded (step S120).
Here, the first predetermined time t1 is 3 seconds. When it is determined in step S120 that the elapsed time T does not exceed the first predetermined time t1, the process proceeds to step S130.

In step S130, the stop button 144 is pressed.
It is determined whether or not is turned on. Here, if it is determined that it is not in the on state, that is, it is in the off state, the timer is reset (step S140), and this processing is ended. Note that the stop button 144 is pressed in step S130.
If it is determined that is ON, the procedure returns to step S120.

On the other hand, when it is determined in step S120 that the elapsed time T exceeds the predetermined value t1, the CPU 102
The process proceeds to step S150. That is, step S1
20 and the processing of S140, the stop button 144
When is turned off, the timer is reset,
Only when the ON state of the stop button 144 continues for the first predetermined time t1 or more, the process proceeds to step S150.

In step S150, the process of extending the nozzle position of the nozzle device 12 is executed. In this process, the drive motor 45 is driven, the nozzle 13 is extended from the stored state by a predetermined distance, and the nozzle 13 is moved to the cleaning position. At this time, the nozzle 13 only extends, and water is not ejected from the nozzle head 13b of the nozzle 13. That is, the first opening / closing valve 37a and the second opening / closing valve 37b of the opening / closing valve unit 37 are kept closed. Further, in place of the structure in which water is not discharged from the nozzle head 13b, a structure in which a small amount of cleaning water is discharged within a range in which the cleaning water does not reach the outside of the toilet body 5 from the nozzle head 13b, that is, the first opening / closing valve 37a or The second on-off valve 37b may be in a slightly opened state.

The nozzle extending operation described above is performed only when the stop button 144 is kept on for the first predetermined time t1 or longer. However, the nozzle extending operation is not limited to the above configuration. Nozzle 13 may be provided so that the nozzle 13 can be quickly extended when this switch is operated.

As a result of step S150, the user can confirm that the nozzle main body 13a of the nozzle 13 and the nozzle head 1 at the tip thereof.
3b can be wiped and cleaned. Then, it is determined whether or not the stop button 144, which has been pressed so far, is turned off (step S160). Here, when it is determined that it is not in the off state, that is, it remains in the on state, the CPU 102 performs the process in step S17.
Advance to 0.

In step S170, it is determined whether or not the elapsed time T obtained by the timer exceeds the second predetermined time t2. Here, the second predetermined time t2 is 10 seconds, which is longer than the first first predetermined time t1.
If it is determined that the elapsed time T does not exceed the second predetermined time t2, the process returns to step S160. on the other hand,
When it is determined that the elapsed time T exceeds the second predetermined time t2, the process of retracting the nozzle position of the nozzle device 12 to the storage position is executed (step S180). In this process, the drive motor 45 is reversed and the nozzle head 13b is housed in the casing 11. After that, the timer is reset (step S185), and this processing ends.

On the other hand, in step S160, the stop button 1
If it is determined that 44 is in the off state, the CPU 102
Advances the process to step S190. That is, according to the processing of steps S160 and S185, the stop button 1
When the state in which 44 is in the ON state continues for the second predetermined time t2 or more, the nozzle 13 is housed in the casing 11. This is because when the stop button 144 is in the ON state for a second predetermined time t2 or more,
It is judged that the button switch is short-circuited, and the nozzle 1
3 is stored.

In step S190, a process for starting acceptance of an interrupt routine, which will be described later, is performed, and then this process is terminated.

The interrupt routine executed by the CPU 102 will be described in detail with reference to the flowchart of FIG. This interrupt routine is repeatedly executed every predetermined time after the acceptance is started in step S190.

When the processing is started, the CPU 102 first determines whether or not the stop button 144 is in the on state (step S200), and determines whether or not the seating sensor 6a is in the on state (step S200). S210), it is determined whether the user has operated any button other than the stop button 144 to input those signals from the operation panel 14 (step S220), and the elapsed time T determined by the above-described nozzle cleaning routine. Determines whether the time exceeds the third predetermined time t3 (step S230). Here, the third predetermined time t3 is 3 minutes, which is longer than the first predetermined time t1.

When all the steps S200 to S230 are answered in the negative, "return"
Then, the process ends once. On the other hand, step S2
When a positive determination is made in any of steps 00 to S230, the process proceeds to step S240, and the process of retracting the nozzle position of the nozzle device 12 to the storage position is executed. In the process, the drive motor 45 is reversed and the nozzle head 13b is housed in the casing 11. However, at the housed position (in the state where the nozzle head 13b is located in the cleaning chamber 43), the cleaning water is discharged from the nozzle head 13b. It is also possible to adopt a configuration in which a nozzle self-cleaning process for ejecting the above is added. With this configuration, the cleaning water ejected at the storage position is reflected on the inner surface of the cleaning chamber 43, and the ejection port of the nozzle head 13b can be cleaned. Then, the interrupt acceptance is terminated and the timer is reset (step S250) so that this interrupt processing routine is not executed thereafter, and thereafter,
This interrupt routine ends.

As described above in detail, according to the toilet sanitary washing device 10 of this embodiment, when the user presses the stop button 144 for 3 seconds or more, the water discharge from the nozzle 13 is stopped, The drive motor 45 is driven to extend the nozzle 13 to the cleaning position (steps S100 to S100).
150). As a result, the user can easily clean the nozzle body 13a and the nozzle head 13b of the nozzle 13. In this state, when the stop button 144 is pressed (step S200), the cleaning work is considered to be completed, the nozzle 13 is housed in the casing 11 (step S240), and the user sits on the toilet seat 6. The nozzle 13 is housed in the casing 11 also when it is detected (step S210). Therefore, when the user forgets to operate the stop button 144 and tries to use the stool with the nozzle 13 extended, the nozzle 13 is immediately stored in the casing 11. It doesn't get dirty.

When the extended state of the nozzle 13 continues for the third predetermined time t3 or longer, the nozzle 13 is immediately housed in the casing 11 for the purpose of preventing the nozzle 13 from being left for a long time. To be done. Therefore, the adhesion of dust to the nozzle 13 can be minimized.

Further, when the user operates a button other than the stop button 144 with the nozzle 13 extended, the nozzle 13 is housed in the casing 11.
Therefore, the user is not limited to operating the stop button 144, but simply operates any switch in the operation panel 14 to
The nozzle can be stored. Therefore, the nozzle 13
Is easily accommodated, and secondarily, the nozzle 13 is prevented from being extended to the cleaning position and left unattended.
In this embodiment, when any switch in the operation panel 14 is operated, the nozzle 1 in the extended state is
However, these switches are not necessarily limited to those inside the operation panel 14, and any switches that can be operated by the user may be used. For example, in the sanitary washing device 10 configured to include a switch group similar to the operation panel 14 as a remote controller,
The nozzle may be stored even when the remote control is operated.

Further, according to the toilet sanitary washing device 10 of the above embodiment, when the nozzle 13 is stored in the storage position in step S240, the spout is washed by the reflection of the washing water from the nozzle 13. It is configured. When the nozzle is stored in steps S210 to S230, unlike when the nozzle is completely cleaned and the nozzle is intentionally stored, the cleaning of the nozzle is not necessarily completed. The spout can be washed to help clean the nozzle 13.
