1, static arc double force fan
Applying the principle of "Coanda" fluid mechanics, a "V-shaped static arc" is innovated at the bottom of the fan, which can reverse the smoke, make the oil fume suction smoother, and effectively reduce the turbulent resistance and noise (the oil fume needs to turn 90 degrees twice to form a turbulent area when entering the ordinary fan); Colleagues adopt double-sided impeller design, forming negative pressure areas on the front and rear sides of the fan, which doubles the suction.
2. Smoke guiding adsorption technology
Tai Fang's new range hood revolutionized the use of "Coanda smoke guide plate", and its design tilted 28 degrees outward, forming a exhausting convex surface, thus having Coanda effect (also known as wall attachment effect). Firstly, the lower air inlet sucks the oil fume at close range, so that the oil fume can quickly approach the smoke guide plate; Due to the wall-attached effect of director Cohen's version, the oil smoke is adsorbed on the surface of the smoke guide plate and rises orderly along the smoke guide plate; When the oil fume enters the upper air inlet, the pressure here increases due to the shrinking space, and the oil fume is quickly inhaled.
3. Variable R ventilation duct
Experts from Tai Fang Aerodynamics Laboratory (National Laboratory) invented the national patent technology "Variable R Worm Tongue" fan system (patent number: 01kloc-0/32056.7) after years of painstaking research. "Variable R volute tongue" can effectively offset part of the noise generated by motor operation and airflow movement, and minimize the internal noise of the range hood.
At the same time, inspired by Nautilus' natural perfect spiral, Tai Fang invented Nautilus' smooth suction duct, which was designed in strict accordance with Nautilus' smooth logarithmic curve. Because the flow direction of oil fume in the volute is completely consistent with the volute curve, there is almost no vortex and turbulence, which effectively ensures the aerodynamic force, reduces the resistance, makes the rehearsal smoother and has stronger suction.
4, patent near Chang network
Taifang Jingchang Network innovatively adopted the design of "double rows of annular oil guide grooves in the same direction". The surface of the oil guide groove is semicircular and staggered in the same direction. The parallel spacing is 7.4mm, and the spacing between the upper and lower floors is 2.5 mm The wind resistance reaches the minimum value, and the intake air reaches the minimum value, so that the intake air is smoother and the suction force is stronger.
5. Without disassembly and washing technology, the air intake is smoother.
There are three key technologies for cleaning after disassembly: washable inner core, worry-free net and variable R ventilation duct. The washable inner core solves the problem that the "disassembly-free and washing-free" lampblack machine core can not be disassembled and cleaned. Just remove a screw, the impeller can be taken out for thorough cleaning and maintenance, and the strong power of the machine core can be maintained for a long time.
Summary: Only innovative companies can develop. Tai Fang invests hundreds of millions of dollars in scientific research every year, creating the myth that the industry is the first and innovation is the primary productive force. It is expected that other domestic enterprises can be as brave in innovation as Tai Fang and strive for world class.
