Detailed ways

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

As shown in Figure 1, an indoor water-saving tank 1 is arranged below the roof of one of the floors (hereinafter referred to as this floor) of the multi-storey housing structure (that is, the floor 15 of the upper floor of the house), and the upper part of the indoor water-saving tank 1 There is waste water collecting pipe 12, and waste water collecting pipe 12 communicates with the water outlet of washing machine 9 and the water outlet of washbasin 10 in the residential room on the upper floor. For the house with floor drain 13 structures, the water outlet of washing machine 9 can be connected with The waste water collecting pipe 12 is connected. The bottom of the indoor water-saving tank 1 communicates with the flushing port of the indoor urinal 8 of this floor through a water pipe, and the sewage outlet of the urinal 8 is still communicated with the original sewer. A water meter 3 and a water valve 4 are arranged on the water pipe between the indoor water-saving tank 1 and the flushing port of the urinal 8 .

The urinal 8 in the room of this floor is provided with a urinal cover 7 , and the outer edge of the urinal cover 7 is a water collection chamber structure provided with a plurality of water collection holes, and the water collection chamber communicates with the waste water collection pipe 12 .

The urinal 8 or the flush toilet in the room of this floor are still communicated with the original running water pipe 5, and when the domestic waste water discharged on the upper floor is not enough for flushing the urinal or the flush toilet, it can be flushed with tap water as usual.

For the house that is provided with bathtub 11 indoors on this floor, the water outlet of bathtub 11 is also communicated with waste water collecting pipe 12 .

On the outer side of the outer wall of the above-mentioned multi-storey building, an outdoor water-saving tank 2 is arranged at a position consistent with the height of the indoor water-saving tank, and the outdoor water-saving tanks 2 of each floor are communicated through a downpipe 16 .

Below the floor 15 of the lowest floor of the above-mentioned multi-story building, a waste water collecting pipe 12 is also arranged, and the inlet end of this waste water collecting pipe is communicated with the water outlet of the washing machine 9, wash basin 10 and/or bathtub 11 in the residential room, And the outlet port communicates with the outdoor downpipe 16 .

During use, the domestic wastewater discharged from the washing machine 9, wash basin 10, bathtub 11, etc. in the residential room on the upper floor is collected and discharged into the indoor water-saving tank 1 in the residential room of the next floor through the waste water collecting pipe 12; The upper floor of the residence, the urinal cover 7 can be covered on the urinal 8 first, so that the shower water can enter the water collection cavity through the water collection hole on the urinal cover 7 and then be discharged to the next floor of the residence by the waste water collection pipe 12. In the indoor water-saving tank 1, the shower water is prevented from being directly discharged through the urinal 8 and cannot be reused. For the dwelling house that flush toilet is installed, toilet lid can be covered, and shower water is discharged in the indoor water-saving tank 1 of next floor dwelling house through waste water collecting pipe 12 again through floor drain 13. In order to avoid bathing dirt such as hair blocking waste water collecting pipe 12, filter screen can be installed at the entrance of urinal cover 7, bathtub 11, floor drain 13. Residential users on this floor, open water valve 4, then can flush urinal 8 or flush toilet with the domestic waste water in the indoor water-saving tank 1, then discharge into sewer by the blowdown pipe 14 of urinal 8 or flush toilet.

If the user on the next floor does not use the domestic waste water from the indoor water-saving tank 1 or the amount used is not as high as that of the previous floor, the indoor water-saving tank 1 can be discharged to the outdoor water-saving tank 2 through the connecting pipe 17, and then discharged through the downpipe 16. Into the outdoor water-saving tank 2 or the sewer of the next floor, without causing the overflow of domestic waste water.

Based on the calculation of the population of four in each household, each person goes to the toilet seven times a day, and the average water used for flushing the toilet is 2 kilograms each time, then each household has an annual flushing water of 20,450 kilograms. And every person in each household takes a bath every two days, then each person takes a bath 60 times a month, and each time uses about 30 kilograms of water, so each household uses 21,600 kilograms of water per year, plus washing, laundry, hand washing, brushing teeth, etc. All kinds of domestic water are collected, and the amount of water collected by each household into the indoor water-saving tank is enough for the downstairs users to flush the toilet.

The whole water-saving device is low in cost, and is also suitable for the transformation of old commercial houses, hotels, and dormitories, and the installation cost of new houses is not high.
