In order to solve the problems of traditional electric water heaters, we have developed an electromagnetic instantaneous water heater, which adopts advanced high-frequency inverter electromagnetic induction heating technology and water flow detection technology, which effectively overcomes the safety problems, low efficiency, and short service life of traditional electric tungsten wire heating., etc., it has the characteristics of high efficiency and energy conservation, stable water production, less scale formation, water and electricity isolation, etc., and has functional designs such as overvoltage and overcurrent protection, over-temperature protection of power devices, and water interruption and dry burning protection; Heating elements are resistant to vibration and impact and have a long life.
When heating water, current passes through the induction coil to heat the cavity to generate eddy currents and generate heat, instantly heating the flowing water. The control circuit is mainly composed of a microprocessor and peripheral digital circuits, pulse driving circuits, water flow sensors and other parts. Under the program control of the microprocessor, it can automatically control the start/stop of the inverter according to the situation, and has functions such as water cut protection. In addition, when the inverter occurs under abnormal conditions such as overcurrent and overheating, the microprocessor can adjust the working frequency according to the current and voltage phase signal output by the inverter, so that the inverter can work in the best resonant state [This point is the key technology]. The magnetic induction water heating system has high heating efficiency, with a theoretical value of more than 95%, which saves 30% electricity compared with tungsten wire electric heating tube water heaters. When hot water is not used, the water storage electric water heater still needs to continuously apply electricity to the stored water to maintain thermal insulation. However, the invention uses water immediately after heating, saves electricity significantly, and meets the requirements of low-carbon economy.
Although different companies have always been developing electromagnetic water heaters, there are no successful developers at home and abroad due to technical bottlenecks in control algorithms, heater structure and materials used. Therefore, for this technology and products, based on in-depth search, the company believes that our products and technologies are the first at home and abroad, and has applied and authorized multiple patents for this purpose.
Complex control algorithms, clever structures and heating body materials optimized through multiple experiments, especially the invention patents declared and authorized based on these technologies, are huge advantages for the company in in-depth research and development and industrialization promotion of this related product.
