Recently, a number of technologies of Midea's kitchen heating gas appliance project "Research and Application of Directional Oxygen Supplementation and Double Internal Flame Combustion Technology for Gas Cooker" and "Research and Application of FOC Control Technology of Plastic Permanent Magnet Synchronous Motor in Gas Water Heater" have reached the "international leading" level after being identified by the expert group. Midea Kitchen Heating won another award under strict standards, thanks to its own solid promotion of core technology progress, once again demonstrating the first-class technical level.
The achievements of technology research and development are fruitful, and the authoritative recognition shows the power of intelligent innovation
The appraisal was hosted by the China Light Industry Federation, and the appraisal committee composed of industry experts and professors highly affirmed the innovation ability of Midea's industrial technology, and identified a number of key technologies of Midea's kitchen heating gas appliance project to reach the "international leading" level, providing excellent technical support for Midea's gas water heaters and gas cookers, and effectively promoting the high-quality development of China's kitchen heating industry after these revolutionary innovative technologies are implemented.
The directional turbine oxygen supplementation technology of the gas stove and the double internal flame combustion technology have made breakthroughs and formed a leading edge
Midea brings together doctors of thermodynamics and gas appliance industry experts for 965 days of painstaking research, a total of more than 50 patents, and 10 invention patents have been authorized. Under the traction of energy conservation and environmental protection, an important national strategic goal, Midea will launch a new gas stove with high energy efficiency of 80%, far exceeding the national first-class energy efficiency standard of 63%, and will be launched in July this year. This gas stove applies the "international leading" level 4D directional oxygen supplementation and wing standing vortex energy structure, which reduces the flame height under the best excess air coefficient, so that the red fire is not hypoxic, the flame is fully burned, and the fire power is stable. In addition, the Midea team focused on the core demands of users to stir-fry and produce fragrant, and developed a miniaturized double internal flame combustion system, which makes the hot air flow evenly spread from the center of the rigidity to form an upward eruption of hot gas cyclone, and the 45° swirling flame grasps the bottom of the pot, the fire type is stable and evenly stored, and the 3-level blowing cannot be extinguished, and the fragrance level far exceeds the first-class standard, so that the ingredients can achieve the ideal cooking effect in a very short time, so that users can easily make a chef-level delicious dish with pot gas and steaming at home.
The gas water heater is equipped with FOC control technology of permanent magnet synchronous motor with plastic structure, which has reached the international leading level
Based on user needs, technological innovation is the underlying logic of enterprise development and survival. Midea's strong drum series gas water heaters are equipped with "international leading" level plastic structure permanent magnet synchronous motor FOC control technology, and adopt the industry's first integrated drive and control integrated packaging technology to support the highly integrated three-in-one inverter chip, which can reduce the electronic components by 50% and the volume of the driver board by 50%. The BMC stator and rotor unequal distance high-efficiency motor was developed, and the power density of the motor was increased by 18%. In response to the potential safety hazards of flue gas exceeding the standard of the constant speed motor, the constant current motor of Midea's strong drum series gas water heater realizes automatic air supply by ensuring a constant current, even if the machine is running at a small load, it is still sensitive to external wind pressure changes, safe and reliable. In addition, based on the principle of aerodynamics, Midea reconstructed the fan flow channel structure, the industry's first non-equal-thickness, small-diameter ratio centrifugal fan, the maximum static pressure of the fan was increased by 25%, the size of the fan impeller was increased to 84*45.8mm, the wind resistance of the DC inverter fan was better and more reliable, and the wind resistance level of the gas water heater was increased from a 9-level typhoon to a 11-level typhoon, calmly coping with the windy weather, and leading the popularization of motor inverter technology in the whole industry. It is worth mentioning that Midea's newly launched non-cold gas water heater S9 is also equipped with this technology, which ensures that there is no skin temperature difference in the water use process from multiple dimensions such as temperature control, stable combustion, and safety, bringing a more comfortable bathing water experience to Chinese families.
For a long time, Midea Kitchen Heating has been based on the height of science and technology, and has continuously made breakthroughs in core technologies and the layout of various patents. We have reason to believe that Midea, as an industry leader and innovator, will continue to lead the development trend of the kitchen heating industry, do a good job in the in-depth refinement of achievements, contribute the wisdom and power of beauty, and continue to bring consumers more comfortable, convenient and intelligent products.
