Totally-enclosed household water-saving system

Technical Field

The invention relates to the technical field of water saving, in particular to a fully-closed household water saving system.

Background

The shortage of water resources is a long-term problem faced by human beings, and the fresh water resources all over the world only account for 2.5% of the total water quantity, but the fresh water resources which can be really utilized by human beings are part of rivers, lakes and underground water and only account for 0.26% of the total water quantity of the earth ball. It is estimated that by 2025 the world population will be over 25 billion in water shortage. China is a country with severe drought and water shortage, the per-capita water resource amount is only 2300 cubic meters, which is only 1/4 in the average level in the world, and the country is one of the most scarce per-capita water resources in the world, and water conservation is urgent.

When a family uses hot water through a water heater for heating, cold water which does not reach the bathing temperature in a pipeline is discharged before hot water is discharged from a shower, and tap water which can be drunk is used for flushing a toilet on the other side. According to statistics, the water for flushing the toilet accounts for about 21% of the total water consumption of the building, and through the actual test of the inventor, when a kitchen water heater is used for supplying hot water, about 6.82L of cold water is discharged before hot water is discharged in the toilet (the lengths of pipelines are different, and the numerical values are different). According to the seventh census data, the population residing in towns was 9.02 million people. Assuming that each person uses hot water once in the morning and evening, the total quantity of tap water wasted in China per day reaches 0.123 billion cubic meters, the total quantity of water wasted in the whole year reaches 44.9 billion cubic meters, a large quantity of water resources are wasted, and meanwhile, 44.9 billion cubic meters of sewage to be treated are increased, and the water treatment cost is increased. Assuming that the direct cost of tap water wasted by each household of three households per year would reach 37.4 yuan, calculated according to the water price of tap water of 2.5 yuan/cubic meter, the value would reach 112.25 billion per year in the country, and there is no small expenditure for each household and even the whole country.

At present, most towns, communities and water treatment plants lack corresponding measures for recycling reclaimed water. And to the waste water cycle recycle system of single family, need the water pump to pump waste water usually, increased family's power consumption to a certain extent, still have great power consumption potential safety hazard, and waste water exists and exposes contaminated risk, hardly reaches municipal water supply quality of water, disinfectants such as aquatic chlorine residue volatilize and lead to concentration not enough to lead to the waste water in the container to breed the bacterium easily, the user is lower to waste water reuse acceptance. Therefore, it is very important to develop a totally-enclosed pollution-free household water saving system without electricity, and for this purpose, a totally-enclosed household water saving system is provided, which uses the existing household water supply and drainage equipment as a basis and combines a newly-designed valve bank, a faucet, a pressure water storage container and the like to form a complete totally-enclosed pollution-free household water saving system without electricity, so as to achieve the purpose of water saving.

spherical water outlet in the backflow elbow 37, when cold water enters the overflow valve 3, under the action of water pressure, the upper blocking ring 41 compresses the tightening spring 39, when the upper blocking ring 41 slides over the water outlet hole in the shell 35, the initial section of cold water above the upper blocking ring 41 enters the shell 35 through the water outlet hole in the shell 35 and finally enters the pressure water storage tank 4 through the first pipeline 9, at this time, the lower plug 42 synchronously returns to the spherical water outlet hole in the backflow elbow pipe 37, so that the backflow elbow pipe 37 does not discharge water, when the pressure water storage tank 4 reaches the maximum water storage volume (when the water pressure in the pressure water storage tank 4 reaches the water pressure in the hot water pipe 14, the maximum water storage volume is reached), at this time, the water pressures on the upper and lower sides of the upper blocking ring 41 are basically equal, the resultant force of the water pressure acting on the upper blocking ring 41 is reduced to zero, the upper blocking ring 41 is pushed up again under the action of the tightening spring 39 and tightly clings to the upper cover plate 40, the lower plug 42 is pulled up together with the upper blocking ring 41, therefore, water on the upper blocking ring 41 enters the return pipe 8 through the return elbow pipe 37 and finally returns to the water outlet of the water tap 1 to remind people that the pressure water storage tank 4 is full of water, when the priority water distribution valve 5 is not communicated with water, the movable water distribution column 46 is tightly attached to the top cover 47 under the action of the tension spring 48, at the moment, a tap water outlet hole above the right side of the movable water distribution column 46 is blocked by the three-head shell 44, the water outlet hole of the pressure water storage tank 4 below the right side of the movable water distribution column 46 is aligned with the water outlet branch pipe on the right side of the three-head shell 44, the water of the pressure water storage tank 4 is kept communicated with the toilet, when both ends of the three-head shell 44 are communicated with water, the pressure of the pressure water storage tank 4 on the movable water distribution column 46 and the tension of the tension spring 48 are greater than the pressure of tap water on the movable water distribution column 46 in the tap water connecting pipe 16, the movable water distribution column 46 moves upwards, so that the water of the pressure water storage tank 4 is kept communicated with the toilet, the water in the pressure water storage tank 4 is preferentially used, and when the pressure of the pressure water storage tank 4 acting on the movable water distribution column 46) + (the tension of the tension spring 48) is smaller than the pressure of the running water in the running water connection pipe 16 acting on the movable water distribution column 46, the movable water distribution column 46 moves downwards, so that the running water and the toilet bowl are kept in a communicated state, the standby running water is started, and the water in the pressure water storage tank 4 is preferentially used after the water storage amount of the pressure water storage tank 4 is increased next time and the pressure is increased.
