In the toilet bowl cleaning device as described above, when the power is turned on, the motor is first rotated in the normal direction, and the operation lever is rotated in conjunction with the forward rotation drive of the motor. It is possible to recognize that the motor has operated normally when the power is turned on.
After that, a pairing work is performed to synchronize the rotation of the operation lever with the cleaning start trigger (for example, the operation of the cleaning start button provided in the toilet room) other than the method of manually rotating the operation lever, and pairing is performed. When the ring is completed, the motor is rotated in the normal direction, and the operation lever is rotated in conjunction with the forward rotation drive of the motor, so that the installer can recognize that the pairing is completed.
In this way, by driving the motor when the power is turned on and driving the motor when the pairing is completed, if either of them does not operate normally, the installer may have an abnormality in the motor or an abnormality in the pairing. It is possible to detect if there is a problem and to recognize the cause of the abnormality.

On the other hand, if the specifications are as described above, the pairing may be completed while the operation lever is automatically rotated when the power is turned on when the toilet bowl is installed. In that case, the motor drive is performed. It is done only once, and the installer may not be able to recognize the completion of pairing. Then, the builder may mistakenly think that there is an abnormality in the pairing even though the pairing is completed.
On the contrary, even though the pairing is not completed, the installer mistakenly recognizes that the pairing was completed while the operation lever was automatically rotated when the power was turned on, and as a result, the pairing was completed. There is a risk that the enforcement work will be completed without being completed. In that case, even if the user presses the cleaning start button in the toilet room, the toilet is not cleaned because the motor is not driven.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a toilet bowl cleaning device capable of suppressing a builder from misunderstanding about the completion of pairing.

The toilet cleaning device according to one aspect of the present invention is a toilet cleaning device that supplies cleaning water to the toilet body to clean the toilet, and is provided on the tank body for storing the washing water and is rotatable.

First, the installation / installation of the toilet bowl main body 10 and the toilet bowl cleaning device 100 in the toilet room is completed (step S100). After that, the power plug 140 connected to the control means 120 is inserted into the outlet C to turn on the power (step S101). When the power is turned on normally in step S101, the operating lever 113 automatically rotates in one direction (clockwise) by driving the motor 115 in the forward rotation (steps S102 and 103). At this time, the large cleaning is also performed at the same time by the automatic rotation of the operating lever 113 in one direction (clockwise). As a result, the builder can visually confirm that the power is turned on normally, and at the same time, the operation of the large cleaning of the toilet bowl can be confirmed by actually cleaning the toilet bowl.

After performing the power-on step in steps S101 to 103, the installer performs a pairing operation so that the motor 115 is driven when the cleaning switch 130 is operated (step S104). When the cleaning switch 130 and the motor 115 are normally paired in step S104, the operation lever 113 automatically rotates in the other direction (counterclockwise) by the reverse drive of the motor 115 (step S105, 106). At this time, small cleaning is also performed at the same time by automatically rotating the operating lever 113 in the other direction (counterclockwise). As a result, the builder can visually confirm that the pairing of the cleaning switch 130 and the motor 115 has been performed normally, and at the same time, the operation of the small cleaning of the toilet bowl can be confirmed by actually cleaning the toilet bowl. can.
In this way, by completing the power-on step in steps S101 to 103 and the pairing step in steps S104 to 106, a series of toilet bowl execution work of the flush toilet bowl 1 is completed.

Next, using the time chart of FIG. 4, a case where pairing is completed in the middle of the power-on process will be described.

Next, at time t2, the pairing operation is completed before the forward rotation drive of the motor 115 is completed (in the middle of the power-on process). At this time, the operation lever 113, the motor 115, and the toilet bowl are continuously washed during the operation. After that, at time t3, the rotation operation of the operation lever 113 and the drive operation of the motor 115 are completed.

At time t4, the large cleaning performed from time t1 is completed. At this time, since a sufficient amount of washing water for cleaning the toilet bowl is not stored in the tank body 111, the washing water is stored in the tank body 111 from time t4 to time t5.

Then, at time t5, the motor 115 is reversely driven. This is an operation associated with the completion of the pairing work at time t2. By the reverse drive of the motor 115, the operation lever 113 rotates in the other direction (counterclockwise), and small cleaning is started in the toilet bowl cleaning.

Then, at time t6, the rotation operation of the operation lever 113 and the drive operation of the motor 115 are completed. Then, at time t7, the small cleaning performed from time t5 is completed.

<Action effect>
Next, the operation and effect of the toilet bowl cleaning device 100 according to the above-described embodiment of the present invention will be described.
The toilet bowl cleaning device 100 drives the motor 115 when the power-on process of automatically rotating the operation lever 113 by driving the motor 115 when the power is turned on and the pairing of the cleaning switch 130 and the motor 115 are completed. This has a pairing process for automatically rotating the operation lever 113, and the rotation mode of the operation lever 113 is different between the power-on process and the pairing process, and the operation lever 113 is in the middle of the power-on process. When the pairing is completed in, the pairing process is performed after the power-on process is completed. As a result, the builder can prevent the rotation operation of the operation lever 113 in the process of turning on the power from being mistaken as the rotation operation of the operation lever 113 due to the completion of pairing, and has the pairing been completed? It is possible to surely recognize whether or not, and it is possible to prevent misunderstanding about the completion of pairing.

Further, the toilet bowl cleaning device 100 automatically rotates the operation lever 113 in one direction (clockwise) by driving the motor 115 in the forward direction in the power-on process, and performs a large cleaning in the pairing process. By reversely driving the motor 115, the operating lever 113 is automatically rotated in the other direction (counterclockwise), and small cleaning is performed. As a result, it is possible to prevent misunderstanding about the completion of pairing, and it is also possible to confirm the toilet bowl cleaning operation at the same time as the toilet bowl execution work.

Although the embodiments of the technique disclosed in the present application have been described above, the technique disclosed in the present application is not limited to the above.

In the above-described embodiment, the operation lever 113 is automatically rotated in one direction (clockwise) by driving the motor 115 in the forward direction in the power-on process, and the motor 115 is driven in the reverse direction in the pairing process. By automatically rotating the operation lever 113 in the other direction (counterclockwise), the rotation form of the operation lever 113 differs between the power-on process and the pairing process. Not limited to this.
For example, as shown in FIG. 5, in the power-on process, the motor 115 is driven in the forward direction to automatically rotate the operation lever 113 in one direction (clockwise) by a first predetermined amount, and in the pairing process. The motor 115 was driven in the forward direction to automatically rotate the operating lever 113 in one direction (clockwise) by a second predetermined amount less than the first predetermined amount, and the operating lever 113 was rotated in one direction (clockwise). Occasionally, the toilet bowl cleaning may be performed when the rotation is performed by an amount larger than the second predetermined amount. As a result, since the amount of rotation differs between the power-on process and the pairing process, it is possible to prevent the builder from misunderstanding the completion of pairing. In addition, the toilet bowl is not washed in the pairing process. This is because the operation of the toilet bowl cleaning has already been confirmed in the process of turning on the power, so that it is not necessary to confirm the operation of the toilet bowl cleaning again in the subsequent pairing process. Therefore, waste of washing water can be suppressed. On the contrary, it may be automatically rotated by a second predetermined amount in the power-on process and automatically rotated by the first predetermined amount in the pairing process.

Further, in the above-described embodiment, the automatic cleaning instruction means is the cleaning switch 130 provided on the wall surface of the toilet room, but the present invention is not limited to this, and the seating provided on the toilet seat, for example, as the automatic cleaning instruction means. It may be a switch or a human body detection sensor that detects a human body in a toilet room.

The elements included in each of the above-described embodiments can be combined as long as technically possible, and the combination thereof is also included in the scope of the present invention as long as the features of the present invention are included.
