Description
Technical Field
The invention belongs to the technical field of water saving, relates to a pre-discharge cold water circulation technology, and particularly relates to a pre-discharge cold water circulation system and a method based on a backflow pipe coupling thermistor combination.
Background
The water resource is an indispensable resource in life, can be obtained through river runoff, underground water, accumulated snow, glaciers, lake water, marsh water, seawater and the like, and is an extremely important renewable resource. More than about 70% of the earth's surface is covered by water, and the remainder, about 30% of the earth's surface, is also occupied by water. The total water volume of the earth is 1.386 x 1018m3Wherein the fresh water reserve is 3.5 x 108 hundred million m3Accounting for 2.53% of the total reserves. Seawater, deep groundwater, ice and snow solid fresh water, etc. are rarely directly used due to development difficulties or technical economic limitations. The lake, river and shallow underground fresh water resource which is easy to develop and utilize and has the most close relationship with human life and production only accounts for 0.34 percent of the total reserve of fresh water and is 104.6 multiplied by 104 hundred million m3And less than one ten-thousandth of the total water storage of the whole world. The water resource is mainly the fresh water resource which is available and can be recovered and updated year by year. Therefore, the fresh water resources on the earth are not abundant.
Although water is a renewable resource, its quantity and rate of regeneration are limited. Moreover, the water distribution is extremely uneven. With the development of economy and the increase of population, the water consumption of the world increases year by year. In recent years, with the reduction of water resources in the world, it is urgent to effectively utilize water resources without wasting them. In daily life of residents, before the water heater normally outputs hot water, residual water and cold water which does not reach the set temperature in the hot water pipe can be discharged in advance, and waste is caused. According to investigation, one person wastes about 7.56 hundred million tons of water every year because of the waste amount of cold water discharged in advance of nearly 1.5kg every day.
The invention patent CN201721101195.4 provides a cold water pre-discharge valve and a shower head provided with the same, wherein the cold water is assembled from an inner core and a water passing hole through a water inlet channel to form a water passing gap, the flow rate is small, and the principle that linear water flow cannot be generated is adopted, so that the slow water outlet of the outlet water flow is controlled, and the discomfort caused by just opening a large amount of cold water is avoided. But the recycling of cold water is not obviously improved, and in addition, the structure of the cold water pre-discharge valve is complex, the number of parts is large, and the difficulty of installation and maintenance is high. The invention patent CN202010985981.5 adds a cold water pre-discharge gear on the existing constant temperature shower to block the cold water pipeline, so that only the residual cold water in the hot water pipeline is discharged, after the cold water is discharged, the water tap is automatically closed to prompt the user to discharge the cold water completely to achieve the effect of cold water pre-discharge constant temperature, however, the discharged water is not processed and utilized in detail.
