First, the range hood is composed of fan system, control system, oil filter device, housing and suspension device. Fan system is the heart of the range hood machine, usually composed of a motor and impeller, a range hood power size, is also determined by the fan system. The control system is the most scientific and technological component of the smoke machine. There are micro circuit boards to control the power and switch of the smoke machine. Oil filter device mainly refers to the net and oil filter chamber. The shell and suspension device are generally made of stainless steel, which is resistant to high temperature and corrosion.
Range hood is the use of aerodynamics as the basic principle of design and development, its action principle can be summed up as: negative pressure, suction, separation, discharge. The steps are as follows:
1. The motor drives the impeller with coaxial connection to rotate while running.
2. The rotating agitation of the impeller makes the fan blade of the range hood produce rapid updraft.
3. The air flow forms a vortex negative pressure area near the air inlet, which makes the lampblack gas rise rapidly.
4, when the lampblack runoff to the oil network, rotation friction, so that the lampblack separation.
5. After the grease adheres to the oil net and accumulates to a certain amount, it will flow into the oil cup along the oil guide column due to gravity.
Lampblack machine is not only the lampblack discharged indoors so simple, lampblack separation is the biggest role of lampblack machine; Soot separation is made use of a principle of physics: the weight of the oil molecular weight slightly larger than the smoke, so after tell movement within the separation plate, oil molecules will be a strong centrifugal force to separate plate, oil molecules together to form oil droplets, affected by gravity and slipped to oil cup, so eduction outdoor not lampblack, but smoke.
Working principle of range hood: Turn on the oil absorption power, drive motor, make rotor high-speed rotation, make cooking range above a certain range of space form negative pressure zone, the interior of the lampblack suction gas oil absorption, oil gas through the oil filter, for the first time lampblack separation, and then into the machine inside the air duct, with the rotation of the turbine to the lampblack of the second separation of oil gas, The oil fume in the air cabinet is subjected to the action of centrifugal force, and the oil mist condenses into oil droplets, which are collected into the oil cup through the oil circuit. The purified smoke is finally discharged along the fixed channel.
