By operating the setting switches 28 and 29, it is possible to adjust the length of the setting time described later.

  As shown in FIG. 2, the control circuit 41 receives signals from the seating sensor 9, the stop operation switch 26, the delay operation switch 27, the setting switches 28 and 29, and the switches 21 to 25, and is installed in the water supply pipe 34. Control signals can be transmitted to the solenoid valve (not shown), the sound device 7, the solenoid valve (not shown) of the hot water cleaning device 33, and the display panel 31.

  As shown in FIG. 2, the toilet bowl cleaning device 40 includes these control circuit 41, seating sensor 9, stop operation switch 26, delay operation switch 27, setting switches 28 and 29, water supply pipe 34, and sound device 7. .

  Next, an operation example of the toilet bowl cleaning device 40 will be described.

<Operation Example 1 (Operation Example when Switches 26 and 27 are not Operated)>
When the user sits on the toilet seat 3 and finishes using the seat, the seating sensor 9 transmits a leaving signal to the control circuit 41 when the user leaves the toilet seat 3. When the control circuit 41 receives this separation signal, the timer starts. When a predetermined time t ₁ (for example, 7 seconds) elapses from the start of the timer, the control circuit 41 transmits a control signal to the audio device 7, and the speaker 7a of the audio device 7 notifies the automatic cleaning described later. The cleaning warning sound is generated. Thereafter, when a set time T (for example, 10 seconds) elapses after the timer is started, the control circuit 41 transmits a control signal for opening the electromagnetic valve (not shown) of the water supply pipe 34, and the electromagnetic valve is predetermined. Open for hours. Thereby, automatic cleaning of the toilet bowl is performed. In this automatic cleaning, the same cleaning as the large automatic cleaning (for example, 6 L) is performed.

  If the user operates the main switch 21 or the small switch 22 between the start of the timer and the lapse of the set time T, the automatic cleaning or small cleaning of the toilet is performed at that time. Automatic cleaning is performed. Further, even if the timer is stopped and the set time T elapses, the automatic cleaning is not performed again.

  The set time T is set in advance by operating the setting switches 28 and 29. For example, it is set when the toilet cleaning device is installed in a toilet room. When the setting switch (large) 28 is operated, the setting time T is lengthened, and when the setting switch (small) 29 is operated, the setting time T is shortened.

  In the above operation example, the cleaning warning sound is generated only once (for example, 3 seconds before the start of automatic cleaning), but may be uttered twice (for example, 5 seconds before and 3 seconds before the start of automatic cleaning). Well, it may be uttered three or more times. The cleaning warning sound may be a mechanical sound such as “beep” or a language such as “automatic cleaning starts in another 5 seconds”.

<Operation Example 2 (Operation Example when Delay Operation Switch 27 is Operated)>
When the user sits on the toilet seat 3 and finishes using the seat, the seating sensor 9 transmits a leaving signal to the control circuit 41 when the user leaves the toilet seat 3. When the control circuit 41 receives this separation signal, the timer starts.

When the user operates the delay operation switch 27 between the start of the timer and the elapse of the set time T (for example, 10 seconds), the delay operation switch 27 transmits a delay operation signal to the control circuit 41. When the control circuit 41 receives this delay operation signal, the timer is reset and restarted. When a second predetermined time t ₂ (for example, 3 seconds) elapses after the timer is restarted, the control circuit 41 transmits a control signal to the audio device 7, and the speaker 7a of the audio device 7 performs automatic cleaning described later. A cleaning warning sound is generated to notify the user. Thereafter, when a delay time T ₁ (for example, 7 seconds) elapses after the timer is restarted, the control circuit 41 transmits a control signal for opening the solenoid valve (not shown) of the water supply pipe 34, and the solenoid valve Is opened for a predetermined time. Thereby, automatic cleaning of the toilet bowl is performed.

Incidentally, during the period from the timer is restarted until the delay time T ₁ is passed, if the user has operated the Daiyo switch 21 or urination switch 22 Daiyo automatic cleaning of the toilet at the time Or, a small automatic cleaning is performed. Thus when a large switch 21 and urination switch 22 is operated, the timer is stopped, it never automatic washing again carried out even after the elapse of the delay time T ₁ is.

<Operation Example 3 (Operation Example when Cancel Operation Switch 26 is Operated)>
Next, an operation example when the user operates the stop operation switch 26 while the automatic cleaning is being performed according to the operation examples 1 and 2 will be described. Here, “while the automatic cleaning is being performed” means that the automatic cleaning is being performed after the set time T has elapsed in the operation example ₁ while the delay time T ₁ has elapsed in the operation example 2 and is automatically performed. It means that the large-scale automatic switch 21 or the small-scale automatic cleaning is being performed by operating the large switch 21 or the small switch 22 in the first and second embodiments.

  When the user operates the cancel operation switch 26 while the automatic cleaning is being performed, the cancel operation switch 26 transmits a cancel operation signal to the control circuit 41. When the control circuit 41 receives the stop operation signal, the control circuit 41 transmits a control signal for closing the electromagnetic valve (not shown) of the water supply pipe 34, and the electromagnetic valve is closed. Thereby, the automatic cleaning of the toilet is stopped. Thereafter, when the user operates the large switch 21 or the small switch 22, large automatic cleaning or small automatic cleaning is performed. In the rim-jet-rim cleaning pattern, when the stop operation switch 26 is operated during the jet timing, the jet is immediately stopped and a constant amount of water can be allowed to flow from the rim. Thereby, when it stops with a jet, it can prevent that sealing water runs out and an odor returns.

  The advantages of this operation example are as follows. That is, while automatic cleaning is being performed in accordance with the first and second operation examples 1 and 2, it may be desired to use an object to be washed such as toilet paper in order to wipe the toilet bowl or bite the nose. In this case, in order to wash the object to be washed with water using the automatic cleaning during this implementation, it is necessary to use the object to be washed in a hurry, which is inconvenient. In addition, there is no armor using the object to be washed in such a manner, and there are cases where it is not in time for this automatic cleaning. In this case, it is necessary to operate the large switch 21 and the small switch 22 again to perform the automatic cleaning of the toilet only in order to allow the used water washing object to flow, and water consumption increases. According to this operation example, since the automatic cleaning can be stopped during the automatic cleaning, the object to be washed can be used without panic. In addition, by operating the large switch 21 and the small switch 22 after throwing away the used washing object in the toilet bowl, the used washing object can be reliably washed with water. Furthermore, compared with the case where the automatic cleaning is performed again after the automatic cleaning is completely completed, the amount of water used is reduced by the amount that the first automatic cleaning is stopped halfway.

In this operation example, the timer is stopped when the stop operation switch 26 is operated, but the present invention is not limited to this. For example, when the stop operation switch 26 is operated, the timer is reset and restarted, and when the second set time T ₂ (for example, 10 seconds) has elapsed, the toilet bowl may be automatically washed. . Thereby, even when the user forgets to operate the large switch 21 or the small switch 22, the toilet is surely automatically cleaned. In this case, before the second set time T ₂ elapses, a cleaning warning sound for notifying the automatic cleaning may be generated. By operating the delay operation switch 27, the second set time is set. T ₂ may be further delayable.

  The above embodiment is an example of the present invention, and the present invention is not limited to the above embodiment.

  That is, in the above embodiment, the cancel operation switch 26 provided on the remote controller is used as the cancel operation means, but the present invention is not limited to this. For example, the stop switch 25 of the remote controller 20 may also serve as a stop operation switch. In this case, when the stop switch 25 is operated during automatic cleaning, it may function as a stop operation switch. A stop operation switch 26 may be provided in the toilet seat box 2.

The stop operation means may be a toilet seat rotation detection means for detecting the opening operation of the toilet lid 4. For example, the toilet seat rotation detection means and a toilet lid rotation device that closes the toilet lid 4 when the user leaves the toilet seat are installed in the vicinity of the connecting portion between the toilet seat box 2 and the toilet lid 4. In this case, the user when lifted, toilet lid 4 is closed, the setting time T, the automatic cleaning after a T ₂ or the delay time T ₁ is performed. When the user opens the toilet lid 4 during the automatic cleaning, the toilet lid rotation detecting means detects it and transmits a stop signal to the control circuit 41, whereby the automatic cleaning is stopped.

  The cancel operation unit may be a voice detection unit that detects a user's voice and transmits a stop signal to the control circuit 41. In this case, when the user generates a word such as “Wait” during automatic cleaning, the voice detection means detects this occurrence and transmits a stop signal to the control circuit 41, whereby the automatic cleaning is stopped.

These toilet seat rotation detection means and voice detection means may be used as the delay operation means. In this case, if the user opens the toilet lid 4 or speaks a word such as “waiting” before the set time T elapses after the user leaves the seat, the toilet seat rotation detection means or voice The detecting means transmits a delay operation signal to the control circuit 41. Thus, automatic cleaning of the toilet is carried out after a delay time T _1.
