technical field

The utility model relates to a water-saving device for reusing domestic waste water such as washing water, washing water and other domestic waste water for flushing toilets. the

Background technique

The secondary utilization of domestic wastewater is an effective measure to make full use of water resources. At present, domestic toilets are generally flushed with tap water, and the waste water discharged from the bathroom wash basin is directly discharged into the sewer, while the waste water discharged from the wash basin has better water quality and less impurities, and does not require additional purification devices. Therefore it will be a powerful measure to save water and alleviate the shortage of water resources by reusing the waste water discharged from the bathroom wash basin to the toilet. Utilize household waste water to be used for this field of flushing toilet at present, similar product does not appear yet. There are some similar patents. Chinese Patent Announcement No. 202925620U (announcement date 2013.05.08) discloses a "domestic domestic waste water utilization device". Consumes power, takes up limited space and increases costs. the

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:

In the figure, a water storage tank 10 is set at a place 100-200mm higher than the full water level of the toilet water tank, and the water storage tank 10 is connected with the wash basin 1 by a bouncing drainer 2; the overflow pipe 5 passes through the left bottom of the water storage tank 10, and its lower end The sewer pipe is connected, and its upper end nozzle is flush with the water storage surface; the water outlet at the bottom of the water storage tank 10 is connected to the drain pipe 7, and a one-way valve 6 is installed on the drain pipe 7, and the other end of the drain pipe 7 is connected to the tee pipe 8 The tap water inlet pipe 3 is connected to the water storage tank 10 from the left side, then passes through the bottom of the water storage tank 10 right side and is connected with the tee pipe 8 on the drain pipe 7, and the water level control valve 4 is installed on the tap water inlet pipe 3 pipelines in the water storage tank 10 The other interface of the three-way pipe 8 is connected to the toilet water tank inlet pipe 9, and the toilet water tank water inlet pipe 9 is connected to the toilet water tank pipeline inlet. Described bouncing water device 2 is known technology. the

The domestic waste water in the washbasin 1 flows into the water storage tank 10 through the bouncing drainer 2, and when the waste water in the water storage tank 10 is too much, the unnecessary waste water is discharged through the overflow pipe 5. the

Below is the embodiment of the utility model work. the

Example 1:

When the amount of waste water in the water storage tank 10 is sufficient, and the waste water level is higher than the position of the water level control valve 4, the tap water inlet pipe 3 controlled by the water level control valve 4 is in a closed state. One-way valve 6, three-way pipe 8, toilet water tank inlet pipe 9 supply the toilet water tank, and when the water tank of the toilet was full, the known water level control valve of the water tank of the toilet closed the waste water pipeline. the

Example 2:

When waste water is not enough in the storage tank 10, and the water level is lower than the height of the water level control valve 4, the tap water inlet pipe 3 controlled by the water level control valve 4 is unimpeded now, and when the toilet needs water, the tap water just passes through the tap water inlet pipe 3, the water level control valve 4, Tee pipe 8, toilet water tank inlet pipe 9 enter the toilet water tank, because the drainpipe 7 is provided with check valve 6, tap water just can not flow into water storage tank 10, when the water tank of the toilet is full, the known water tank of the toilet The water level control valve shuts off the tap water line. the

Example 3:

When the water level of the water storage tank 10 is slightly higher than the water level control valve 4, the tap water inlet pipe 3 controlled by the water level control valve 4 is closed. The toilet water tank inlet pipe 9 supplies the toilet water tank, but when the waste water drops to the position of the water level control valve 4, if the toilet water tank is still not full, the water level control valve 4 is opened, and the tap water passes through the tap water inlet pipe 3, the water level control valve 4, Tee pipe 8, toilet water tank inlet pipe 9 supply the toilet water tank, and when the water tank of the toilet was full, the known water level control valve of the water tank of the toilet closed the running water pipeline. the
