Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a water supply device. More specifically, it is a car wash waterer that is used, for example, at the time of car washing, and supplies water by detecting payment by a fee element, not only when a preset time is reached but also at a preset time. The present invention relates to a device for stopping water supply when the amount of water has been reached.
[0002]
[Prior art]
For example, many places such as condominiums and apartments have a car wash space at one corner of the apartment complex. A water tap is provided in the car wash space, and the user can freely wash the car using a hose connected to the tap.
[0003]
However, as described above, in the case of an uncharged water supply system in which the amount of tap water used is unlimited and unlimited use, it is impossible to expect the user to save water.
This causes the water bill to be large, and considering that the water bill is paid by the management fee that is equally collected by the resident, it is important for those who use the water supply facilities and those who do not. I can't deny the feeling of being unfair.
[0004]
Then, in order to correct the above-mentioned unfairness, the number of apartment houses provided with a water supply device provided with a billing system has been increasing. In such a water supply device, a timer is set when a user inserts a coin, and the water supply device can be used for a predetermined period of time (for example, see Patent Document 1).
[0005]

[Problems to be solved by the invention]
However, the water supply device that can be used only for a certain period of time as described in the above-mentioned publication can supply water without any particular restrictions until the time has elapsed, so that the user does not need to discharge water every time. There is a strong tendency to leave water out because it is troublesome to stop. For this reason, water was easily wasted.
[0007]
(Object of the present invention)
An object of the present invention is to stop water supply not only when a predetermined time has elapsed but also when the water supply amount has reached a predetermined amount, so that water is wasted during a set time when water can be supplied. An object of the present invention is to provide a water supply device and a water supply method for performing car washing and the like that can suppress use.

(Action)
The water supply device according to the present invention operates as follows.
When the user pays the fee according to the fee element, the amount is detected based on, for example, the number of coins.
The water supply amount is set to a water amount set in advance corresponding to the paid fee (amount). The time during which water can be supplied is also set to a time that is set in advance in accordance with the paid fee.
At the start of use, the elapsed time of water supply is measured by the time measuring means, and the amount of water supply is also measured by the flow rate measuring means. At the same time, the elapsed time of water supply and the set time are compared, and the amount of water supply and the set water amount are compared.
[0017]
If the water supply amount reaches the set water amount earlier than the water supply elapsed time reaches the set time, water supply is stopped when the water supply amount reaches the set water amount.
Conversely, if the elapsed time of water supply reaches the set time earlier than the amount of water supply reaches the set water amount, water supply is stopped when the elapsed time of water supply reaches the set time.
As a result, even if the water supply elapsed time has not reached the set time, the water supply is stopped when the water supply amount reaches the set water amount. Wasteful use of water can be suppressed.
