Description of the Related Art Automated flush toilets have been desired in response to the aging society, or electric automatic toilet flushing apparatuses have become widespread as auxiliary means for nursing care. A problem of the electric automatic toilet cleaning device is a countermeasure against a power failure during driving, that is, a means for switching from electric to manual. The electric automatic toilet cleaning device cannot flush flush water in the event of a power outage, or runs off in the event of a power outage during cleaning, and thus must be manually operated.

The system automatically switches to manual mode to cope with a power failure. As a second means, there has been devised a switch which uses a clutch mechanism by a planetary gear and can be used together with a manual operation. In this mechanism, in one washing process in a normal electric operation, the motor is rotated by a predetermined angle each time to open a drain valve, and then the motor is temporarily stopped in order to discharge water stored in the tank, and the drain valve is stopped. The motor will be rotated back to maintain the open state and then after a predetermined period of time to turn off the wash water, returning the drain valve to the closed state.

Move to However, the internal gear region 15b1 is formed along the orbit of the planetary gear 45, and the internal gear region 15b1 does not prevent the planetary gear 45 from revolving in the direction of arrow A1. Therefore, the planetary gear 45 resumes its revolution when the meshing with the internal gear region 15b1 starts, and passes along the internal gear region 15b1. During this time,
The planetary gear 45 is provided with a negative pressure applied to the drain valve and the return spring 30.
The output gear 15 is gradually returned to the starting position, and functions to turn the drain valve from the fully opened state to the closed state.

明を省略する。When the engagement between the planetary gear 45 and the internal gear region 15b1 is released, the output gear 15 and the output shaft 16 are opened and closed by the load of the drain valve and the urging force of the return spring 30.
2 and return to the starting position, and the drain valve is closed. The planetary gear 45 continues to revolve even after the meshing with the internal tooth region 15b1 is released, and when returning to the starting point, the implant 46a of the connecting arm 46 switches off the switch 55 to turn off the motor 13
Stop and end one cycle. The process in which the planetary gear 45 revolves from the starting point in the direction of the arrow A2 and meshes with the internal gear region 15b2 is the same, except that the direction is reversed.

までの動作時間は非常に早く、節電効果が期待できる。After the planetary gear 45 is disengaged from the internal gear regions 15a and 15b of the output gear 15, it does not interfere with any member until it meshes with the fixed tooth portion 50 immediately before reaching the starting point. Therefore, the planet gear 45 revolves very quickly, and no torque cross occurs. Therefore, the planetary gear 35
However, the operation time until the planetary gear 35 moves to the starting point and switches the switch 55 to stop the motor 13 after the drain valve is switched from open to closed due to disengagement with the internal tooth regions 15a and 15b is extremely short. As soon as possible, a power saving effect can be expected.

１４と噛合可能な位置に復帰する。In the above configuration, if a power failure occurs in a state where the planetary gear 45 is not meshed with the output gear 15, the output gear 15 is completely free without being restrained. When the opening and closing member 12 connected to the output shaft 16 is rotated to open and close the drain valve, the output shaft 16 is naturally moved to the neutral position by the urging force of the return spring 30 when the hand is released. Then, the output gear 15 returns to a position where it can mesh with the gear train 14 by the urging force of the compression spring 26.

遊星歯車４５との噛合位置に向かって付勢される。In this state, the manual lever shaft 18 can be freely rotated left and right manually without interference from the gear train 14, and the output shaft 16 integrated with the manual lever shaft 18 connects the opening / closing member 12 to the open / close member 12. Since it can rotate integrally, the drain valve can be opened and closed manually, and the washing operation can be completed even during a power failure. When the manual lever 18a is released, the output spring 15 is returned to the starting position by the return spring 30, and the output gear 15 is urged toward the meshing position with the planetary gear 45 by the urging force of the compression spring 26. .

However, since the opening / closing member 12 does not move in the axial direction,
The axial deviation of the output gear 15 does not affect the drain valve. When the power failure recovers and the remaining cycles have elapsed, the mechanism of the toilet cleaning device 10 returns to the initial starting point. Since the opening and closing member 12 does not move in the axial direction, the drain valve can always maintain a constant function by a predetermined manual operation.

付けることができるので品質が安定する。The opening / closing member is rotatably attached to the case bearing independent of the mechanism from the outside, and the sliding is restrained by the locking ring, so that the opening / closing member operates only by the mechanism regardless of the axial accuracy of the opening / closing member. Characteristics can be checked, and accuracy is stabilized. Further, the strength of the bearing portion is improved, and the run-out of the output gear due to the reaction of the opening / closing member can be prevented. In addition, since the opening and closing member and the output shaft only transmit rotation, slight misalignment can be ignored. Since the opening / closing member can be attached after checking the characteristics of the mechanism section, the quality is stabilized.

することができる。As described above, since the opening / closing member can be formed separately from the mechanism, the processing and assembly of the opening / closing member are facilitated, and the problem of warpage caused by integrating the opening / closing member with the mechanism is reduced. Thus, the opening and closing of the amount of water becomes stable. Further, since the opening / closing member and the mechanism section can be packed separately, the packing space is reduced, and the cost can be reduced. Moreover, it is possible to respond to a customer's request for design change only by replacing the opening / closing member.
