Description

A-FIELD-TOILET WATER FACILITIES FOR RECYCLING OF RAINWATER}

The present invention relates to a water supply facility for outdoor toilets for recycling rainwater, and more particularly, water for outdoor toilets for recycling rainwater that can be recycled to the permeable pavement layer, the surface, roof, and wastewater drained from the sink. It is about facility.

In general, outdoor toilets are installed in places where a large number of people gather, such as outdoor public places such as parks or event halls.In recent years, outdoor toilets are installed for transportation as needed. Mobile outdoor toilets are also used.

Since toilets and sinks in outdoor toilets can be used only when water is supplied, it is essential to design a pipeline for water supply.

However, since the installation area of the outdoor toilet is mostly the area without a constant pipeline, there is a huge cost for water supply, that is, the cost is greater than the cost of the outdoor toilet itself. In addition, in terms of maintenance, the cost of using a water source is incurred, and in the situation where water shortage due to climate change is intensifying, efficient rainwater recycling is a natural problem and has a problem to be solved nationally.

In order to solve this problem, there have been proposed technologies for recycling water thrown out of the sink and recycling for collecting rainwater. However, since the conventional recycling technology is fragmentary, the amount of reclaimed water is very small. There is only the concept of using, but it does not lead to the effect of substantially reducing the use of constants.

In order to install the first filter 15a in front of the first inlet 15, a separate porous wall filter unit may be configured. The filter parts may be integrally formed with the reservoir body 11.

The first rainwater collecting means is a rainwater (road water) penetrating the permeable pavement layer (3) is guided to the rainwater reservoir (10) without seeping into the ground, the pitcher aggregate (3a), which is installed in a certain thickness in the ground, It is composed of a waterproof sheet (3b) is laid on the bottom of the permeable aggregate (3a) to guide rainwater to the first inlet. It is preferable that the permeable aggregate 3a and the waterproof sheet 3b are inclined downward while going to the first inlet hole 15 so that rain water penetrating the permeable pavement layer 3 smoothly flows into the first inlet hole 15. .

The second inflow portion is for introducing the surface water on the ground surface of the rainwater reservoir 10, the storage tank through a plurality of second inlet hole 16, the second inlet hole 16 formed in the cover 12 And a second filter 16a for purifying surface water flowing into the main body 11.

The second inflow hole 16 may be formed according to the structure of the cover 12 so that rainwater is concentrated and supplied to the center, and the second inflow pipe 16c may be applied to prevent shaking due to falling rainwater. have. The second inlet pipe 16c may have the same structure as the first inlet pipe 15c, and a water collecting plate 16d is connected to the upper end thereof. The collecting plate 16d must be supported to be detachable from the work hole 13 of the cover 12, because the work hole 13 must be opened during cleaning or maintenance of the reservoir body 11.

The second inlet hole 16 may be transversely drilled in the wall protruding from the cover 12 to have the work hole 13 as shown in the drawing, in which the second filter 16a is placed on top of the cover 12. It is installed up to the height of the second inlet 16 to purify surface water. The second filter 16a can also use the same filter method as the first filter 15a, 15b, and the structure of the cover 12 will be changed according to the filter method (active carbon type, filter net type, etc.) Since it will be possible to implement the specific description and drawings will be omitted.

In order to increase the purification effect, a mesh filter net 16b may be applied to the upper portion of the first filter 16a. The filter net 16b may be modified in various ways, such as in the form shown in the drawings.

The second rainwater collecting means may be configured to allow the surface water to smoothly flow into the second inflow portion, and may be formed through the above-described second inflow portion or may use a configuration of the first rainwater recovery means.

The third inlet is for storing the rainwater collected on the roof of the outdoor toilet (1) in the reservoir body (11), both sides of the roof and the reservoir body of the outdoor toilet (1) to solve the height difference with the roof ( 11) a third filter 17a for purifying rainwater introduced through the roof inlet pipe 17 and the roof inlet pipe 17 connected therein.

The third rainwater collecting means may be a drain duct 17b having an inflow side collected so that the rainwater collected on the roof of the outdoor toilet 1 is introduced, and the discharge side of which is connected to the roof side inlet pipe 17. The roof side inlet pipe 17 and the drain duct 17b are described separately, but this may be a single pipe.

The fourth inlet is a fourth filter for purifying the water flowing through the wash basin side inlet pipe 18 and the basin side inlet pipe 18 connected to both sides of the drainage system of the wash basin and the reservoir body 11. Is done. The fourth filter may be configured exclusively for the sink side inlet pipe 18, or may share the third filter 17a, as shown in FIGS.

The fourth rainwater recovery means is connected to the drain pipe (2a) of the sink 2 to store the waste water as shown in Figure 5 in the recovery tank (2b), the recovery tank (2b) connected to the sink inlet pipe 18 It consists of the filter 2c attached, and cleans the waste water drained from the sink 2, and supplies it to the sink side inflow pipe 18.

At this time, foreign matters such as soap bubbles are suspended in the recovery tank 2b, and the foreign matter drainage pipe 2d may be applied so that the foreign matters are not reused. The foreign matter drainage pipe 2d recovers the foreign matter from the recovery tank 2b in an overflow manner and discharges it through the drainage treatment pipe 4.

On the other hand, in the rainy season, rainwater can be collected more than the capacity of the rainwater reservoir 10, it is impossible to change the volume of the rainwater reservoir 10 is configured not to store a certain amount of rainwater, for example, the reservoir body (11) An overflow portion 19 is formed in the. The overflow portion 19 may be a hole formed at a position higher than the inflow portion in the side wall of the reservoir body 11, and the drainage pipe 4 is piped. Therefore, rainwater cannot be stored beyond the height of the overflow portion 19.

Alternatively, water level sensors, discharge valves, etc. can be configured to drain the rainwater by forcibly opening the discharge valve during high water levels.

In the figure, reference numeral 19a denotes a blocking film that closes the first inflow hole in the sidewall where the overflow portion 19 is located. That is, in the case of the water tank main body 11 having a rectangular box shape, the position of the overflow unit 19 varies according to the position of the outdoor toilet 1, and the first inlet 15 is formed on all sidewalls. The blocking film 19a is applied to utilize the flow unit 19. Therefore, unless only the overflow portion 19 is formed on one sidewall of the reservoir body 11 and the first inflow hole is not formed, the blocking film 19a is not used.

When rainwater is introduced into the rainwater reservoir 10, sludge such as soil or dirt of a small particle size may be introduced together, and the sludge may cause clogging of the use place, so the reservoir body 11 is configured to store sludge.

For example, a porous sludge flow prevention film 40 is mounted to the inside of the reservoir body 11 at a predetermined height from the bottom.

Sludge flow prevention film 40 is the sludge can be introduced, but the shape or size of the hole is determined so that the introduced sludge does not flow back to the top or the sludge does not occur, it is mounted detachably to the reservoir body (11).

Rain water supply means 30 is composed of a water supply pump 31 for pumping rain water stored in the water tank main body 11, the water supply pump 31 and the water supply pipe 32 for supplying the rain water to the use destination. .

Rainwater stored in the rainwater reservoir 10 may be supplied when operating the valve of the place of use, or temporarily stored in a separate small tank (tank connecting the rainwater reservoir 10 and the place of use) and then supplied when operating the valve of the place of use. have.

The controller 20 selects the water supply means based on the detected value of the water level sensor 50, and basically controls the rain water supply means 30 to operate to recycle rainwater, and the detected value of the water level sensor 50 When the reference water level (water level that cannot supply rainwater) is reached, the water supply means is controlled to operate.

Accordingly, the installation position of the water level sensor 50 depends on the amount of water stored in the reservoir body 11, the amount of water used at the place of use, and the like.

Since the water supply means is only selectively operated under the control of the controller 20, and the water supply means is applied to the outdoor toilet 1, a detailed description thereof will be omitted.

The function of the water supply facility for outdoor toilets recycling rainwater according to the present invention is as follows.

Rainwater (road water) penetrates the permeable pavement layer 3 and flows toward the first inlet hole 15 while passing through the permeable aggregate 3a. The first filter 15a-the first inlet hole 15- After the first filter 15b-the first inlet pipe 15c, the water is stored in the reservoir body 11.

The surface water is stored inside the reservoir body 11 through the filter net 16b-the second filter 16a-the second inlet hole 16-the collecting plate 16d-the second inlet pipe 16c.

Rainwater collected on the roof of the outdoor toilet 1 is stored in the reservoir body 11 through the drain duct 17b-the third filter 17a-the roof inlet pipe 17.

Waste water drained from the sink 2 is purified and recovered through the fourth rainwater recovery means and stored in the reservoir body 11 through the sink side inlet pipe 18.

As such, the rainwater around the outdoor toilet 1 is stored in the rainwater reservoir 10, and the water level sensor 50 detects the water level in real time.

The controller 20 compares the current water level by the water level sensor 50 with the reference water level. If the current water level is higher than the reference water level, the controller 20 stops the operation of the water supply means even if the rain water supply means 30 operates.

Therefore, when the user operates the valve in order to use the water in the outdoor toilet (1), the water supply pump 31 of the rain water supply means 30 is operated, the rain water stored in the rain water reservoir 10 is the water supply pipe (32) It is supplied to the place of use.

On the other hand, when the current water level of the rainwater reservoir 10 reaches the reference level (same or lower than the reference level), the controller 20 stops the operation of the rainwater supply means 20 and stops the operation of the water supply means. The water is supplied through the water supply means when the valve at the place of use is operated.
