Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: The present invention relates to public toilets (particularly public toilets installed in parks).

Conventional technology: The floors of public toilets installed in parks are extremely dirty. This is thought to be due to inadequate management and cleaning, not to mention budget constraints.

Problems to be solved by the invention: The present invention aims to solve the problem of how to reduce the amount of dirt on the floors of public toilets installed in parks, regardless of budget considerations. This is an issue that was taken up.

Means for solving the problem: The present invention provides a rainwater receiving recess on the roof,
A filter acting part for collecting and introducing rainwater is composed of the above-mentioned recess and a pipe line hanging down from the recess, and is detachable to separate solid matter such as fallen leaves from the rainwater flowing down through the filter acting part. A filter is provided, and a tank is provided to receive the rainwater from which foreign substances have been separated and removed by the filter, and an automatic siphon device is built into this tank, and the rainwater is automatically drained from the tank one after another by the automatic siphon device. It is characterized by providing a floor washing channel that leads to the drain pipe through the floor part behind the toilet bowl.

Function: The public toilet according to the present invention uses rainwater for cleaning the floor. Rain is collected through a recess in the roof → a conduit that connects to the recess → a removable filter →
The water flows through the tank with a built-in automatic siphon → the floor area behind the toilet → the drain pipe, and contributes to cleaning the floor. The above-mentioned filter is cleaned as appropriate, depending on when foreign matter such as leaves has accumulated inside.

Floor cleaning with rainwater is carried out by applying a relatively high velocity to the rainwater using an automatic siphon.

Example: FIG. 1 is a vertical sectional view of a public toilet according to the invention;
2 and 3 are cross-sectional and exploded views of what is shown in FIG. 1. FIG.

In these figures, 1 and 2 are an outer wall and a roof, respectively, 3 is a rainwater receiving recess provided on the roof, and 4 is a conduit that hangs down from the recess 3. The recess 3 and the conduit 4 constitute a funnel 5 for collecting and introducing rainwater. The rainwater flowing down through the pipe 4 and the connecting pipe 6 passes through a filter 7 to remove foreign matter such as fallen leaves, and then flows into a tank 8.
flows into. The filter 7 is an example of a foreign object trap, which is detachably provided, and is pulled out through a hole 9 on the outer wall 1 at an appropriate time to be cleaned. 10 is an overflow pipe for draining excess rainwater from the tank 8. An automatic siphon device 11 is provided within the tank 8. When the water level in the tank 8 reaches a predetermined value, which is good for rainwater to flow into the tank 8, the automatic siphon device 11 is activated, and the rainwater in the tank 8 is discharged onto the floor portion 14 behind the toilet bowl 13 through the discharge pipe 12. be done. The locations from which rainwater is discharged are selected appropriately, taking into account the ease with which they are likely to become contaminated. Rainwater discharged onto the floor portion 14 from the tank 8 via the discharge pipe 12 is made to flow into the drain pipe 15. The number of rainwater discharge points on the floor portion 14 is often plural. The flow path from the cistern 16 to the toilet bowl 13 to the drain pipe 15 is a normal cleaning flow path using tap water. On the other hand, the flow path of "the funnel action part 5 consisting of the recess 3 on the roof 2 and the pipe line 4" → the flexible pipe 6 → the filter 7 → the tank 8 → the discharge pipe 12 → the drain pipe 15 is specially designed according to the present invention. This is a cleaning channel that uses rainwater.

Effects of the Invention: The public toilet according to the present invention described above is equipped with a floor cleaning device that utilizes rainwater in addition to a normal toilet bowl cleaning device. The latter does not perform any cleaning action as long as the weather is sunny, but it automatically repeats the cleaning of the floor when it rains. This device has the advantage that it does not involve consumption of tap water.
