Coincidentally, on February 2, the annual meeting of the World Economic Forum in Davos proposed that the world will fall into "water bankruptcy" within 20 years, so water may be more valuable for investment than oil. Flush toilets are essential sanitary ware in modern family life, but too much water consumption by flush horses is also a problem. , In the domestic water of residents, flushing water accounts for 27% of the total water consumption. Rough calculations, using a 5-liter water-saving toilet, according to (4 urinations per day, 1 stool per person), the water consumption will be 15 liters per person, and the average daily water consumption will be 45 liters per person for a family of three. Weekly water consumption The volume will reach about 300 liters. If calculated according to the non-water-saving toilet, the water consumption will at least double.

The washing machine is also an essential household appliance in modern life. An ordinary wave-wheel washing machine consumes about 150 liters of water to wash clothes once. If it is calculated twice a week, it needs about 300 liters of water. But relatively speaking, the water quality of the flush toilet The requirements are not very high, so it is feasible to use the water after washing to flush the toilet. If the washing water is dirty and the water requirements are increased, use the rinsed water after filtering, anti-virus and anti-bacterial treatment for flushing The toilet seat fits perfectly.

Through the above analysis, if the combination of washing machine and toilet is used to save water, it is of great practical significance for a family, and more importantly, it can contribute to solving the problem of the country and the lack of fresh water resources on the earth. In practice Advocate the concept of environmental protection and water saving in life.

Patent No.: ZL200520132059.2 utility model patent discloses a reusable water-saving toilet. A waste water inlet line is added to the toilet, and the waste water from the wash basin and washing machine can be used to flush the toilet to achieve the purpose of water saving. The disadvantage of the invention is that there is no special waste water storage device, and the waste water flows directly into the water tank. In almost all cases, the tap water has filled the water tank, and the incoming waste water pollutes the water in the tank and cannot be stored. Save water, but pollute water.

The invention patent of patent application 200510030052.4 discloses a household return water device, which is composed of a drain pipe, a pipeline booster pump, an upper water storage tank, a lower water storage tank, and a return water pipe, which can clean the washing machine and the shower in the later stage. The excess water enters the prefabricated water storage tank through the pumping device and the return pipe for storage, and is used for subsequent flush toilets. The problem of this device is that automatic control cannot be performed between the water in the water storage tank and the toilet, so it brings inconvenience to people's use and cannot be popularized and used.

In view of this, the present invention is proposed.
