JPS5833185Y2 - Water saving device for toilet flushing water - Google Patents

Description

[Detailed explanation of the idea] The present invention relates to a water-saving device for flushing water for toilets such as urinals.

Conventionally, when cleaning multiple urinals in a public place, an elevated storage tank was installed, where the cleaning water was temporarily stored, and when the cleaning water reached a predetermined level, it was allowed to flow down to each urinal. A cleaning method is adopted.

However, in schools, for example, the equipment is only used for a part of the day, and cleaning is performed even when not in use, which means that unnecessary cleaning water is used, which is extremely uneconomical. .

On the other hand, Japanese Patent Publication No. 47-5784, Japanese Patent Publication No. 47199
As described in Publication No. 87 and Japanese Utility Model Publication No. 51-48541, there is no known method of detecting whether a toilet is in use or not, and whether or not there are users, using a phototube, and opening and closing the water supply valve depending on the number of users. It is.

However, this method is expensive in terms of equipment.

The present invention was proposed to address the above-mentioned problems, and focuses on the fact that hand wash basins are generally used after relieving themselves, and water is supplied to the storage tank according to the operation of the wash basin. The purpose of this is to save water for washing.

The present invention will be explained below with reference to embodiments shown in the drawings.
are urinals, and each of these urinals 1, 1, .
is installed.

Reference numeral 4 denotes a wash basin, and above the wash basin 4, a water tap 6 is provided, and a main water supply pipe 7 is connected to the water tap 6.
Further, a water supply system branches from the hydrant 6, and a wash water supply pipe 8 to the tank 2 is provided.

9 is a flow rate regulating valve.

An example of the water tap 6 is shown in FIGS. 2 and 3.

That is, inside the stopper body 60 is a valve rod 6 having two pieces 62a and 62b that are operated by an operation handle 61.
2 is housed inside, and a branch case 63 is screwed into the lower part of the stopper body 60.

The aforementioned main water supply pipe 7 and washing water supply pipe 8 communicate with this branch case 63, and the communication path of the main water supply pipe 7 is always closed by the lower piece 62b.

Further, the communication path of the faucet main body 60 to the faucet is always closed by the upper piece 62a.

64 is a backing. In the device configured in this way, the user uses the washbasin 5 after using the urinal 1.

At this time, when the handle 61 is operated, the pieces 62 a and 62 b open their communication holes as the valve rod 62 rises, and water flows into the branch case 63 from the main water supply pipe 7 .
Water is discharged from the faucet and is also supplied to the tank 2 through the wash water supply pipe 8.

When the hand washing is finished, the water supply is stopped by the top 62b, and the water supply to the tank 2 is also stopped.

Incidentally, the amount of water used is approximately 31 times per wash basin 5, and the capacity of the tank 2 is approximately 151 times per wash basin 5.

Therefore, the flow rate ratio between the water supply flow rate to the faucet and the water supply flow rate to tank 2 is set to 1:1, and the flow from tank 2 to each urinal 1, 1, etc. is only when about 5 people have used it. All you have to do is run the washing water.

Furthermore, if the urinal 1 is not used for a long time, there is a risk that the water sealed in the trap (not shown) provided in the urinal 1 will evaporate.

To prevent evaporation of this sealed water, the top 62 b is always lower.
It is preferable to ensure a small gap between the valve seat and the valve seat so that a very small amount of water can flow into the water supply pipe 8.

The amount of water leakage is adjusted by adjusting the degree to which the case 63 is screwed into the plug body 60.

In addition, in the above example, the operating part of the handwash basin is operated in response to the operation of the operating handle of the water faucet.
It is also possible to use other means to detect whether or not the washbasin is being used, and supply water based on this detection.

As described above, in the present invention, the cleaning water supply pipe is branched from the faucet part, a valve piece is integrally provided on the operation handle, and the water supply is opened and closed via the valve piece when the operation handle is operated. With this arrangement, the presence or absence of a user is detected by the presence or absence of use of the wash basin, so detection is reliable and water used for washing can be reliably saved.

If, as in the above embodiment, water is supplied to the tank simultaneously in response to the operation of the water tap, the equipment will be inexpensive and the water supply operation will be reliable, resulting in significant effects.
