The technical principles used by Aidiwei water heater are: thermal type, continuous type, step type, thermal push type, heat exchange and so on. —— Instant-heating type: Instant-heating water boiler technology is a subversive revolution to the traditional water boiler. It completely abandons the hot water tank, ensures primary boiling, eliminates yin and yang water and thousands of boiling water, measures the temperature with electrodes, and controls the temperature accurately. The outlet water is 111% boiled water, which can be used whenever it is opened. This series has obvious advantages-"intelligent control, reliable performance, water and electricity saving, health and convenience", and will surely become the preferred boiling water solution for schools, factories, hospitals, tea houses, restaurants and other public places. -Step-by-step: Step-by-step energy-saving water boiler adopts advanced technology of step-by-step water replenishment and layer-by-layer heating, which has revolutionized the traditional water boiler. The water boiler that really separates cold water from hot water and ensures the health of one boiling has no yin and yang water, and the electric energy control ensures only one boiling and avoids repeated heating; After adding 1 liter of water for heating and boiling, adding 1 liter of water from the bottom for heating until the water tank is full, so that boiling water can be continuously discharged, thus avoiding the waiting time for the traditional water boiler to take water after the whole tank of water is boiled; The traditional water boiler produces water from the heating box to the incubator by steam expansion, which is equivalent to countless boiling; Electrode temperature measurement, accurate temperature control, water temperature constant at 96-99 degrees; Electronic leakage protection alarm function, electronic temperature control, waterless dry burning prevention, overflow and water leakage prevention function. —— Hot Push Type: (IC card swiping series) Aidiwei IC billing energy-saving water boiler (EK-R121IC) adopts advanced microcomputer program-controlled constant temperature technology, which integrates electronic sensing temperature measurement technology, water level electrode detection technology and integral polyurethane foam insulation technology of water tank. In order to maintain the minimum temperature of healthy drinking water (the national standard stipulates that it is above 95 degrees Celsius), digital signals are obtained by water level electrodes and high-precision temperature sensors, and the work of heating pipes and electromagnetic valves is controlled by microcomputer's precise temperature control and water temperature calculation. The critical boiling technology of feeding water layer by layer and heating layer by layer is adopted to coordinate the boiling water temperature and water intake (water level) in the water tank. At the same time, the laminar flow theory of fluid mechanics and the physical characteristics of boiling water being lighter than cold water being heavier are applied to ensure that the boiling water layer floats upward with the support of the new cold water layer until the electronic temperature sensing point reaches the set value to stop water inflow, so that the new cold water layer entering this time enters an instantaneous heating state and reaches critical boiling to complete the heating cycle of the first water inlet. Only one layer of water is heated at a time, and then another layer of water is added after boiling, so that healthy boiling water with a temperature of 1.111% can be continuously supplied, and "yin and yang water" and "thousand boiling water" are eliminated, thus reaching the standard of healthy drinking boiling water. -heat exchange: (Warm drinking water system) adopts the principle of hot push, cold and heat exchange technology and system cold water control technology, which eliminates the problem of traditional electric valve controlling hot water scaling; By using the cold and hot water pushing technology, the outgoing boiling water releases heat through exchange, and the incoming cold water absorbs heat to preheat and raise the temperature before entering the boiler, thus greatly saving the electric energy and time required for boiling water and further improving the heating efficiency. Second, the technology owned by Aidiwei water heater: intelligent display: temperature, heating, water intake, water level, time, drinking, non-drinking and other working conditions can be displayed in a friendly way; When the night is low and peak, electric heating is performed in sections, and four groups of electric heating tubes can be heated in branches. -Low carbon and energy saving: no noise, no pollution, clean and sanitary, environmental protection, using electricity as heat energy, no heat loss and smoke exhaust heat loss, the thermal efficiency is as high as 98%, and it can make full use of electric heating at night, and can complete 24-hour water supply by combining with heat storage and heat preservation water tank. -Boiling water boiler body: the inner tank is made of high-quality 314 stainless steel, which meets the national drinking water standard. It is welded with special tools, which is corrosion-resistant and greatly prolongs the service life. It is equipped with fiber rubber cotton as insulation layer. The fuselage is made of pure imported 8K mirror high-quality stainless steel plate, and the large-area color matching in the middle is made of imported 314 mirror black titanium gold. The service life of the whole machine is up to 15 years. Electric heating tube: electric heating elements made of high-quality stainless steel electric heating tube or alloy steel are used to ensure safety and durability. electric heating tube uses the principle of slight vibration during work and thermal expansion and contraction to remove scale and increase its service life. -Electrical control: High-performance contactors are selected, with water cut-off protection function and inductive circuit breakers. -week control function: it can be set with Sunday to ensure that the machine is in a shutdown state during the holiday, saving electricity and energy and keeping the water fresh. -Temporary operation function: when the water heater is closed (on weekends), it is necessary to use the water heater without resetting the time, and it can be delayed by one hour according to a temporary operation, which is convenient to use and can save energy more humanely. -backwashing function: at 3 o'clock in the morning every night, the backwashing function is automatically started. After washing the water tank of the water heater for three times, the water can be boiled again, and fresh boiled water can be drunk the next day. —— time switch machine: The water boiler is controlled by microcomputer, which can be set according to the time of going to and from work. It is automatically turned on in the morning and turned off after work to avoid heating at night and during non-working hours, which reduces the invalid working time by 51% compared with the traditional water boiler.
