Description

Description: FIELD OF INDUSTRIAL APPLICATION The present invention relates to an invention for the reuse of water in a home.

[Prior Art] Conventionally, the water used in a house is used only once for each purpose, and after being used, it is directly discharged to the sewer as waste water. For example, hot water used in a bathroom washing room, hot water used in a washing machine, or water used in a washbasin is drained to the sewer as it is.

[Problems to be Solved by the Invention] However, as described above, it is a problem that the water that has been used only once for each purpose in the house is drained to the sewer after use without reuse. There is.

. Since the water is used only once and drained into the sewer, all the water needed for the house will be supplied from new tap water,
There are problems that the cost of water supply will increase, the burden on households will increase, the facilities will also become large for the water supply business that supplies water, and efforts will have to be made to secure water.

. Since the water is used only once and is drained to the sewer, the amount of wastewater discharged to the sewer increases, the usage fee of the sewer increases and the burden on the household increases, and it is necessary to treat a large amount of sewer at the sewer treatment facility. Therefore, there is a problem that the equipment becomes large and the sewage treatment cost becomes high.

. Furthermore, in recent years, the demand for water has been increasing year by year, and there are cases where the supply of water cannot keep up with the demand, such as in the summer, and when the demand for water continues to increase in the future, water resources will be in short supply. From the viewpoint of these water resources, it is a water resource problem that the water used in the house is not reused and is drained to the sewer as it is.

Therefore, it is possible to reuse the wastewater generated in the house as water for cleaning the toilet bowl. For example, the water used in the washing machine is used directly as water for cleaning the toilet bowl.
When washing the toilet bowl, the drainage of the washing machine is not always convenient. Therefore, when the drainage is used as the water for washing the toilet bowl, there is a problem that the supply is not stable, which is not practical. Therefore, it is considered that a sewage tank is provided to collect and store sewage generated in the house, and the water stored in this sewage tank is used as reused water. However, if a sewage tank is installed outside the house, it is not possible to install a sewage tank in each house such as an apartment house, the piping becomes long, and if a sewage tank is installed inside the house, the living space becomes narrow and It is necessary to solve the problems of piping to the tank, problems such as inspection and cleaning of the dirty water tank, odor problems, and safety problems.

The present invention is invented in view of the problems of the above-mentioned conventional example, the object is to reuse the water used in the house in the house, the amount of water used in the house and the amount of drainage. In addition, the wastewater tank for temporarily storing the wastewater for reuse can be arranged by effectively utilizing the dead space of the house, and the piping can be simplified. Can be easily inspected and cleaned, and also prevent odors from getting wet, and prevent children from falling into the dirty water tank even though the inside of the dirty water tank can be easily checked and cleaned. The purpose is to provide a residential water reuse device that can also be used for housing in an apartment complex.

[Means for Solving the Problems] In order to achieve the above object, the residential water reuse device of the present invention has a sewage tank 6 for storing wastewater generated in the house under the floor 50 of the washroom 51, Floor cover on floor 52 of washroom 51
An inspection port 54 having 53 is provided, and a manhole portion 56 of the dirty water tank 6 having a manhole cover 55 is provided below the inspection port 54.

[Operation] Then, the waste water generated in the house is stored in the waste water tank 6, and the waste water stored in the waste water tank 6 is reused as water for cleaning the toilet bowl or the like. By arranging the dirty water tank 6 under the floor 50 of the washroom 51, the underfloor 50, which was a dead space in the past, can be effectively used, and the drainage water from the washbasin 28 can be transferred to the lower dirty water tank 6 by a short pipe. Not only can the water be drained, the washing machine 3 is usually placed in the washroom 5, or next to the washroom 51 or in a washing room provided in the immediate vicinity thereof. Since the bathroom can be drained to the lower sewage tank 6, and the bathroom is usually located next to the washroom 51, the drainage from the bathroom basin 5 can be drained to the sewage tank 6 with a short pipe.
In addition, when inspecting and cleaning the dirty water tank 6,
The floor edge 53 provided at the inspection opening 54 of the floor 52 of 51 is removed, and the manhole cover 55 is further removed to inspect and clean the inside of the dirty water tank 6 at the washroom 51. When the inspection and cleaning are finished, By closing the manhole cover 55 and the floor cover 53, 2
It is possible to prevent heavy odor from flowing into the room, and to prevent children and the like from falling into the dirty water tank 6 by using the double lid.
