By the way, depending on the site where the flash valve device is installed, there are cases of right water supply to which the water supply pipe is connected from the right side to the flash valve device and left water supply to which the water supply pipe is connected from the left side, Therefore, it is desirable to be able to deal with any of the existing flash valve devices when they are replaced with a flash valve device with a controller unit (even if they are newly installed instead of being replaced).

It is possible to configure the flash valve device exclusively for the right water supply and the left water supply, but in this case, the types of the flash valve device are unnecessarily increased, and the required cost is increased accordingly.
In addition, when installing and installing a flush valve device at the site, the left water supply flush valve device was mistakenly brought into the place where it should be the right water supply flush valve device, or the place where it should originally be the left water supply flush valve device was When a flush valve device for water supply is brought in, installation and construction of the flash valve device at the site becomes impossible.

Patent Document 1 listed below discloses a flush valve device with a controller unit that can be commonly used for both right and left water supply.
FIG. 12 shows a specific example thereof.
In the figure, 200 is a flash valve device with a controller unit, and 202 is a cover.

A valve unit 207 is accommodated in the lower cover 206, and the valve unit 207 is fixed to the lower cover 206.
The upper cover 204, together with its internal controller unit, is capable of reversing the mounting direction relative to the lower cover 206 to the left and right.

208 is a sensor window for detecting a human body by a human body detection sensor provided on the upper cover 204, 210 is a part of a water supply pipe formed integrally with the valve unit 207, and 212 is a drain pipe. Part.
The flash valve device 200 is provided with a manual operation unit 214 for manually opening the valve.

In the flash valve device 200, the lower cover 206 and the valve unit 207 accommodated in the lower cover 206 can be installed with the left and right directions reversed while the upper cover 204 and the controller unit inside the upper cover 204 are faced to the front. Therefore, in the case of this flash valve device 200, it is possible to cope with both the right and left water supply with the common flash valve device 200.
However, in this flash valve device 200, the cover 202 is divided into an upper cover 204 and a lower cover 206 for that purpose, and therefore a dividing line (dividing position P) is formed at the joint between the upper cover 204 and the lower cover 206. Thus, there is a problem that the appearance is impaired in the installed state.
