Abstract

PURPOSE: To prevent the return of a nozzle in an extension position to a storage postition even if buttons are pushed at the same time by mistake during the cleaning of the nozzle by separating the stop button from the nozzle adjusting button to arrange them on a control panel. CONSTITUTION: A stop button 144 and a nozzle adjusting button 146 are arranged on positions separated from each other on a control panel 14 of a sanitary washing device. When the stop button 144 is continued to push over three seconds, a CUP 102 of a controller 100 judges whether a seat sensor 6a is on or off. When it judges that the seat sensor 6a is off, a nozzle is extended to a washing position from a storage position as water discharge keeps stopped to make it possible to clean a nozzle main body and a nozzle head. When the stop button 144 and nozzle adjusting button 146 are pushed at the same time under the judgement of the CPU 102 that the cleaning is completed, and the driving motor 45 is inverted to store the nozzle in a casing. Since the stop button 144 is separated from the nozzle adjusting button 146, the return of the nozzle to the storage position by malfunction can be prevented even if both buttons are pushed at the same time by mistake during the cleaning.

A bidet cleaning button 242, a dry button 243, a stop button 244, a water pressure adjustment button 245, and a nozzle adjustment button 246 are provided. The user can use this remote control 24
By operating 0, the sanitary washing device 10 can be made to perform almost the same operation as when operating the operation panel 14.

Next, to clean the nozzle 13, the nozzle 1
The process related to nozzle cleaning for moving the nozzle 3 back and forth between the storage position and the cleaning position will be described in detail below. FIG. 8 is a flowchart showing a nozzle cleaning routine executed by the CPU 102 of the electronic control unit 100. In this nozzle cleaning routine, the user presses the stop button 144 three times.
Execution starts when the button is held down for more than a second.

When the processing is started, the CPU 102 first determines whether or not the user is seated on the toilet seat 6 based on whether or not the detection signal of the seat sensor 6a is in the ON state (step S300). . 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 the seating sensor 6a is determined to be in the off state, the CPU 102 first starts the timer inside the CPU 102 (step S310), and the elapsed time T obtained by the timer is the first time. It is determined whether the predetermined time t1 has been exceeded (step S320).
Here, the first predetermined time t1 is 3 seconds. When it is determined in step S320 that the elapsed time T does not exceed the first predetermined time t1, the process proceeds to step S330.

In step S330, the stop button 144
It is determined whether or not is turned on. Here, if it is determined that it is not in the on state, that is, if it is in the off state, the timer is reset (step S340), and this processing ends. Note that the stop button 144 is pressed in step S330.
If it is determined that is on, the process returns to step S320.

On the other hand, when it is determined in step S320 that the elapsed time T exceeds the predetermined value t1, the CPU 102
The process proceeds to step S350. That is, step S3
20 and the processing of S340, 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 S350.

In step S350, processing for 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. With such a configuration, even if the nozzle head is dry, stains attached when the nozzle head is wiped with a cloth or the like are easily removed due to the presence of a small amount of water. It is also possible to prevent the thread discharge from blocking the water discharge hole and clogging the hole to cause water discharge failure.

Although 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, 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 S350, 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 S360). 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 S37.
Advance to 0.

In step S370, 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 a time longer than the 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 S360. 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 S380). 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 S385), and this processing ends.

On the other hand, in step S360, the stop button 1
If it is determined that 44 is in the off state, the CPU 102
Advances the process to step S390. That is, according to the processing of steps S360 and S385, 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 S390, a process for starting acceptance of an interrupt routine, which will be described later, is performed, and then this process ends.

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 S390.

When the processing is started, the CPU 102 first determines whether or not the stop button 144 is in the on state (step S400). Here, when it is determined that the stop button 144 is in the on state, it is further determined whether or not the nozzle adjustment button 146 (which may be raised or lowered) is in the on state (step S41).
0).

It is determined in step S400 that the stop button 144 is in the off state, or step S41
When it is determined that the nozzle adjustment button 146 is in the off state at 0, the process proceeds to step S420, and it is determined whether or not the stop button 244 of the remote controller 240 is in the on state. Here, if it is determined that the stop button 244 of the remote controller 240 is not in the ON state, it is determined whether the elapsed time T obtained by the above-described nozzle cleaning routine exceeds the third predetermined time t3 (step S430). ). The third predetermined time t3 is 3 minutes, which is longer than the first predetermined time t1.

If it is determined in steps S400 and S410 that both the stop button 144 and the nozzle adjustment button 146 are both in the ON state, step S44.
Go to 0. Further, in step S420, the remote controller 240
When it is determined that the stop button 244 of No. 4 is in the ON state, or when it is determined in step S430 that the elapsed time T exceeds the third predetermined time, step S4
Proceed to 40. On the other hand, steps S400, S420, S4
When the negative judgments are made in order at 30, "return"
Then, the process ends once.

In step S440, a process of retracting the nozzle position of the nozzle device 12 to the storage position is executed. In this process, the drive motor 45 is reversed and the nozzle head 13b is housed in the casing 11. However, at the housed position (when the nozzle head 13b is located in the cleaning chamber 43), cleaning water is discharged from the nozzle head 13b. A configuration in which a nozzle self-cleaning process for ejecting is added may be used. 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. Subsequently, the interrupt acceptance is terminated and the timer is reset (step S450) so that the interrupt processing routine is not executed thereafter, and then the interrupt routine is terminated.

As described in detail above, according to the toilet sanitary washing device 10 of the first embodiment, when the user continues to press the stop button 144 for 3 seconds or longer, the water discharge from the nozzle 13 is stopped. Then, the drive motor 45 is driven to extend the nozzle 13 to the cleaning position (step S300).
~ S350). 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 both the stop button 144 and the nozzle adjustment button 146 are pressed at the same time (steps S400 and S410), it is determined that the cleaning work is completed, and the nozzle 13 is housed in the casing 11 (step S440). . Also, when the stop button 244 of the remote controller 240 is pressed (step S420),
The nozzle 13 is housed in the casing 11.

Since the stop button 144 and the nozzle adjustment button 146 which are arranged apart from each other cannot be pressed by mistake at the same time during the cleaning operation, the nozzle 13 extended to the cleaning position is cleaned by the cleaning person. It is possible to prevent the restoration by the erroneous operation of. Therefore, it is possible to prevent the operation of cleaning the nozzle from being interrupted due to an erroneous operation, and the workability of cleaning the nozzle is improved. Particularly, in this embodiment, the stop button 144 and the nozzle adjustment button 1
Since the existing configuration such as 46 is used, the configuration does not become complicated.

Further, since the stop button 244 provided on the remote controller 240 is not accidentally operated during the cleaning operation, the stop button 244 also causes the nozzle 13 extending to the cleaning position to be cleaned by the cleaner. It is possible to prevent recovery due to an erroneous operation during cleaning by. Therefore, also from this point, it is possible to prevent the operation of cleaning the nozzle from being interrupted by an erroneous operation, and the workability of cleaning the nozzle can be improved.

Furthermore, the third state is when the nozzle 13 is extended.
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 when the predetermined time t3 or more continues. Therefore, the adhesion of dust to the nozzle 13 can be minimized.

Further, according to the toilet sanitary washing device 10 of the above-described embodiment, when the nozzle 13 is stored in the storage position in step S440, the spout is washed by the reflection of the washing water from the nozzle 13. It is configured. When the nozzle is stored in step S430, unlike the case where the nozzle cleaning is completed and the nozzle 13 is stored intentionally, the nozzle cleaning is not necessarily completed. However, with this configuration, the device itself discharges the nozzle. The water outlet can be washed to help clean the nozzle 13.
Of course, nozzle cleaning button 146
When the switch is turned on, or when the stop button 244 of the remote controller 240 is turned on, the device itself can wash the water outlet of the nozzle and play an auxiliary role of cleaning the nozzle 13 by the above configuration. it can.

A second embodiment of the present invention will be described. The toilet sanitary washing device of the second embodiment differs from the toilet sanitary washing device 10 of the first embodiment in the configuration of the operating portion 515.

FIG. 10 is a plan view of the operating portion 515 with a lid (described later) removed, and FIG. 11 is a partial perspective view of the operating portion 515 with the lid open. As shown in both figures, the operation unit 515 of this embodiment includes the same operation panel 14 as that of the first embodiment, and further includes a volume knob group in a recess 550a covered with the lid 550. This volume knob group is operated by opening the lid 550 (FIG. 11). Although not described in detail in the first embodiment, the volume knob group includes the warm water adjusting knob 552, the dry adjusting knob 554, and the toilet seat adjusting knob 556, which are also included in the first embodiment, and further, in this embodiment. A unique cleaning end button 558 is provided. The other hardware configuration is the same as that of the first embodiment.

On the other hand, the software configuration of the second embodiment is different from that of the first embodiment except for the interrupt routine executed by the CPU 102 shown in FIG. FIG.
6 is a flow chart showing an interrupt routine in the second embodiment.
