In the above structure, the object of the present invention can be achieved even if the design of the detailed structure is appropriately changed. For example, the configurations of the transmission member, the valve opening maintaining means, etc. are not limited to those shown in the drawings, and well-known techniques may be appropriately used depending on the overall configuration of the sanitary washing device 100.

As described above, in the water drain valve opening / closing mechanism of the sanitary washing device of the present invention, the left-right lever that is operated when the toilet bowl and the sanitary washing device are disengaged from each other is pushed to operate the water drain valve of the hot water tank. Since it is configured to interlock with the slide rod, even when the sanitary washing device is removed from the toilet bowl, the water drain valve is automatically closed, and when the sanitary washing device and the toilet bowl are engaged, Since the valve cannot be opened, the sanitary washing device and the area around the toilet are not submerged. Further, since the left and right moving levers and the push-pull moving rod are arranged linearly so as to be interlocked with each other, the installation space for the left-right moving lever and the push-pull moving rod can be reduced.

As is clear from the above description, the main body attaching / detaching mechanism of the sanitary washing device according to the present invention has excellent practical effects as listed below. (A) Since the sanitary washing device cannot be removed from the toilet unless the tamper-proof cover is removed, an unspecified large number of users who do not know this cannot unnecessarily remove the sanitary washing device from the toilet. (B) When the sanitary washing device and the toilet are engaged, the transmission member does not operate even if the transmission member attempts to drain water. (C) Therefore, there is no problem that the water supplied into the hot water tank directly flows out to the toilet bowl during use. (D) When the detachable sanitary washing device is removed from the toilet bowl, even if the drain valve of the hot water tank is open, this drain valve is automatically closed in conjunction with this removal operation. (E) Therefore, it is possible to surely eliminate the possibility that some residual water due to the structure of the hot water tank may cause a failure to wet the clothes and floor of the worker. (F) Also, when the sanitary washing device that was once removed is reattached, the water drain valve is always closed, so if you forget to close it as before, the water supplied to the hot water tank will flow directly to the toilet side. There is no inconvenience. (G) The automatic valve closing mechanism can be configured extremely simply by diverting the attachment / detachment mechanism between the sanitary washing device and the toilet bowl. (H) Further, the sanitary washing device is configured such that the left and right moving levers and the push-pull moving rod that operate when the engagement with the toilet is released are arranged in a straight line so that they can be easily interlocked with each other. It is economical because it can reduce the installation space of the push-pull moving rod, increase the degree of freedom in installing functional parts such as tanks, and reduce the size of the entire equipment.
