For example, as a preliminary preparation, the control device 5 opens the clean water connection control valve 31 to introduce water from the water distribution pipe 21 to the water collecting pipe 41, and drives the booster pumps 51, 51, and so on. Then, the intake water flow rate sensor 32 receives that the amount of water introduced from the water distribution pipe 21 to the water collection pipe 41 has reached a predetermined amount, and the clean water connection control valve 31 is closed. The predetermined amount of water means an amount of water capable of continuously injecting water from the injection ports 2, 2 ... To continuously form a roof WR of water having a constant shape.

Then, the control device 5 controls the injection and stop of injection of water from the injection ports 2, 2 ... Based on the presence or absence of signals from the motion sensors 61, 61 and the device switch (not shown).
For example, when the control device 5 is provided on the inlet side of the passage R and inputs a signal from the motion sensor 61 that detects the arrival of the person H, the control device 5 injects water from the injection ports 2, 2 ... When the signal from the motion sensor 61 is not input for a predetermined time or longer, the water injection from the injection ports 2, 2 ... Is stopped.
In this way, the presence or absence of a person is sensed, and the water roof WR forming operation and the water roof WR disappearing operation are performed.

Since the circulating water becomes dirty with the passage of time, the circulating water exchange process for exchanging the circulating water is executed at predetermined time intervals. That is, by opening the sewage connection control valve 33 with the water supply stop control valve 35 closed at predetermined time intervals, a certain amount of water is drained from the circulation water channel 4 to the sewer pipe 22, and then the sewage connection control is performed. By closing the valve 33 and opening the water supply stop control valve 35 and opening the sewage connection control valve 31 and supplying a certain amount of water from the water distribution pipe 21 to the circulation water channel 4, the circulating water is kept constant. Replace only the amount.
The predetermined time may be determined, for example, after verifying the time at which the circulating water becomes dirty by an experiment or the like.
Further, a manual switch (not shown) for instructing the circulating water exchange process may be provided, and the control device 5 may execute the above-described circulating water exchange process when the manual switch is turned on.

According to the first embodiment, a undamaged water roof WR can be formed. In other words, because it is a water roof WR, it will not be damaged.
Since it is a water roof WR, the water roof forming device may be stopped in a strong wind or a typhoon. Even if the water roof forming device is driven in a strong wind or a typhoon, it will not be damaged because it is a water roof WR.
Further, since the roof WR is formed by water, the roof can be formed instantly or the roof can be extinguished instantly, and it can also be used for attractions.

Further, in the configuration using the roof forming bulge as in Cited Document 1, in order to make the left and right roof forming bulges bulge in the horizontal direction, a special structure is used as the roof forming bulge. It is considered that a thing is required, or a guide mechanism for guiding the left and right roof forming bulges so as to bulge in the horizontal direction is required, which may complicate the configuration.
Further, when the roof-forming bulge as in Cited Document 1 is contracted from the inflated state, the contracted roof-forming bulge hangs down from the accommodation cover without being accommodated in the accommodation cover on the tip side. There is a possibility that post-work such as pushing the roof-forming bulge into the accommodating cover by hand or the like may be required so that the appearance is not deteriorated.
On the other hand, the water roof forming device of the first embodiment has a simple device configuration, and can instantly form a roof or instantly form a roof based on the presence or absence of a signal from a motion sensor 61 or a device switch (not shown). The roof can be extinguished. In addition, because it is a water roof WR, it has the advantage of being excellent in aesthetics.
