Moreover, the surface area oil will also fall down smoothly into the oil cup, and will not drip to the cooking surface, which will affect the hygiene.
  • the present invention provides a clean circulation type range hood with a three-dimensional air curtain suitable for Chinese cooking habits, which can completely purify the flue gas, eliminate pollution, and protect the environment. It has many advantages: It can ensure oil-free inside, and it is really free of washing and unloading, which saves time and labor and prolongs the service life of the machine.
  • the photocatalyst can be regenerated on its own and used for a long time. Since the oil absorbing felt has a suction ratio of up to ten times, it can also be used for a long time. Once saturated, it can be replaced with fuel, without secondary pollution, and the price is low, and the replacement is extremely convenient. It can be seen that the invention has the characteristics of cleanness, environmental protection, energy saving, long life, convenient use, and economical comprehensive performance.
