Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an invention for water reuse in residences.

[Prior Art] In the past, water used in residences was used only once for each purpose, and after being used, it was directly discharged into the sewer system as wastewater. For example, the current situation is that other wastewater generated in a residence, such as hot water used in a bathroom washing area, hot water used in a washing machine, or water used in a washbasin, is directly discharged into the sewer system.

[Problem to be solved by the invention 1 However, as mentioned above, the following problems arise when water that has been used only once in a residence is discharged into the sewer system without being reused. There is.

■Water is used only once and then drained into the sewer, so all the water needed in the residence is supplied from new tap water.
There are problems in that water bills are rising, which increases the burden on households, and the water utilities that supply water have to have larger equipment, and they have to make more efforts to secure water.

■Water is used only once and then drained into the sewer system, so a large amount of water is discharged into the sewer system, which increases sewer usage charges and increases the burden on households.Also, it is necessary to treat a large amount of sewage water at a sewage treatment facility. Therefore, there are problems in that the equipment becomes larger and the cost of sewage treatment increases.

■Furthermore, in recent years, the demand for water has been increasing year by year, and there are times when the water supply cannot keep up with demand, such as in the summer.Furthermore, if the demand for water continues to increase in the future, there will be a shortage of water resources. From a water resource perspective, it is a water resource problem if the water used in residences is not reused and is directly discharged into the sewer system.

Therefore, it is conceivable to reuse the wastewater generated in the residence, for example, as water for flushing toilet bowls. For example, water used in washing machines, water used in wash basins, and waste water generated in bathroom washing areas is used directly as water for flushing toilet bowls.
There is not always drainage from the toilets, washbasins, or washing areas, and for this reason, there is a problem of unstable supply when using drainage water for toilet flushing, and washing machine drainage. The wastewater from the washbasin contains lint, hair, and other substances, and if this is used as water for flushing the toilet, it may cause the toilet to become clogged. It is visually undesirable to use the toilet bowl as it is, and there is a problem in that it hinders the comfortable use of the toilet bowl.

The present invention was invented in view of the problems of the conventional examples described above, and its purpose is to provide a stable supply of recycled water when reusing the water used in the residence. Moreover, it is possible to reuse water for residential use by removing debris from the reused water to prevent clogging of pipes, etc., and to improve the filtration rate and to make cleaning, inspection, filter replacement, etc. easier. We are here to provide you with the equipment.

[Means for Solving the Problems 1] In order to achieve the above object, the residential water reuse device of the present invention includes a sewage tank 6 for storing wastewater generated in a residence.
A manhole portion 56 is provided in the sewage tank 6, and a container body 61 having a cylindrical shape with a bottom and a circumferential portion that allows water to pass inside and out is placed below the manhole portion 56 in the wastewater tank 6. The filter 63 is disposed along the circumference of the container body 61, with the end of the drainage supply path 7 for discharging the water in the container body 61 to a place where it is used as reused water connected to the end.

Here, it is preferable that at least a part of the portion of the wastewater supply path 7 introduced into the wastewater tank 6 is constituted by a 7 lexiple hose.

[Function] Therefore, the waste water generated in the residence is stored in the waste water tank 6, and the waste water stored in the waste water tank 6 is reused as water for washing toilet bowls through the waste water supply channel 7. In order to drain the waste water collected in the waste water tank 6 to the waste water supply path 7 side, the waste water collected in the waste water tank 6 is disposed in the waste water tank 6 in a cylindrical shape with a bottom and a peripheral part that allows water to flow inside and outside. The filtered water passes through a filter 63 arranged along the circumference of the container body 61 and enters the container body 61, and the filtered water flows from the container body 61 to the drainage supply path 7. By flowing into the inside of the container body 61 from the periphery, the inflow area into the container body 61 is wide, and efficient filtration is made possible. And inspection,
When cleaning and replacing the filter 63, the container body 61 located directly below the manhole portion 56 is inspected, cleaned, and the filter 63 is replaced. Here, if at least a part of the part of the waste water supply path 7 introduced into the sewage tank 6 is made up of a flexible hose, the manhole part 5 can be
The container body 61 can be removed from the container body 6 to clean the container body 61 and inspect the filter 63.
