Description

technical field [0001] The invention relates to a tap water purification device, in particular to a fully automatic direct drinking hot and cold pure water machine. Background technique [0002] Tap water refers to the water that is purified and disinfected by tap water treatment plants and meets the national drinking water standards for people's living and production use. It mainly draws rivers, lakes, groundwater, and surface water through the water intake pumping station of the water plant; then undergoes processes such as sedimentation, filtration, disinfection, and storage, and finally enters the tap water pipeline at high pressure by the water delivery pump, and transports it to various users through the water distribution pump station . Now the country stipulates that PP pipes should be used instead of the galvanized pipes commonly used in the past, because they will rust over time and cause serious secondary pollution; but at present, most of the tap water pipes sti...

Problems solved by technology

Now the country stipulates that PP pipes should be used instead of the galvanized pipes commonly used in the past, because it will rust over time and cause serious secondary pollution; but at present, most of the tap water pipes still use galvanized pipes

However, most tap water disinfection now adopts the chlorination method. The main purpose of chlorination of public water supply is to prevent water-borne diseases, but there are still certain disadvantages when chlorine gas is used for tap water disinfection. The long transmission pipeline from the factory to the residents' homes will also produce pollution. The corrosion and holes of various parts and pipe joints will produce a lot of rust, which is unavoidable for tap water; at the same time, for the northern region, due to the limitation of regional water sources , the water quality is relatively hard, long-term drinking will cause harm to health

[0003] The tap water cannot be drunk directly, and if it is boiled in time, the residual bacteria, heavy metal arsenic, nitrite and other harmful substances cannot be removed, so the water purifier used to purify tap water is applied, but the existing water purifier , mostly for household use, public water purifiers have the following problems: 1) only hot water and cold water ports are provided, the temperature of hot water is too high, and the temperature of cold water is too low, which are not suitable for direct drinking, and public water purifiers , there is basically no demand for cold water, and direct drinking has not been achieved in the true sense; 2) Simple mechanical and solenoid valve control pipelines are used, and there is no uniform deployment, so that the functions of various pipeline components cannot be fully exerted, resulting in their work. The efficiency is low, and the public requirements cannot be fully met; 3) the purification efficiency is low, because the water demand of the public water purifier is large, and there will be a peak value, so the purification stages of the existing public water purifiers are low, and it cannot reach a relatively high level. High purity, and all without water softening, directly lead to the shortening of the life of the heating equipment, and the increase of maintenance and operation costs; 4) The power consumption is large, because the control device is simple, so the boiling water will be heated repeatedly mechanically, resulting in a large amount of electric energy waste; and because the purity of the water is not high, the energy required for heating will also increase; in addition, the rust of the equipment and the uneven operation of the components make the power increase and increase the power consumption
