Background technology
At present, the range hood on the market roughly is divided into two kinds of end face air intake oil suction cigarette shown in Figure 1 and side air inlet formula range hoods shown in Figure 2 according to mounting means and air intake principle.The installation site of end face air intake range hood shown in Figure 1 is at the top of the kitchen range top, and air inlet is parallel to the kitchen range top, and vertical with body of wall, utilizes soot gas nature rising principle, absorbs oil smoke by end face air intake mode.The installation site of side air inlet range hood shown in Figure 2 is parallel or approximate parallel with body of wall, and air inlet is in the side of the kitchen range top, and near a pot limit, by the mandatory from the side absorption soot gas of mode closely.Two types range hood respectively has its pluses and minuses:
End face air intake range hood shown in Figure 1 is derived from Europe, be adapted to the culinary art custom that the European eats light, few oil smoke, with handsome in appearance, brief fashion, super high power is characteristics, and the principle of utilizing soot gas to rise is naturally absorbed oil smoke by end face air intake mode.This then can satisfy its culinary art demand fully for the European.But shortcoming is: air inlet from the pot face far away (with the pot identity distance from being generally 70cm); Culinary art custom by Chinese prosperous oily vigorous fire, quick-fried capsicum, a large amount of soot gas are in the process that rises, because of diffusion can make part oil smoke both sides or lateral direction escape to the left and right, therefore, end face air intake range hood shown in Figure 1 has only solved upward to the oil smoke that flows, and the oil smoke that subtend both sides or lateral direction diffusion are escaped has just been felt simply helpless, so it is relatively poor to absorb the ability of oil smoke; Common compensating mode is to increase power of fan, but power consumption is also increased thereupon.
Side air inlet formula range hood shown in Figure 2 is more suitable for Chinese culinary art custom, and (a distance pot limit is 10～15cm) usually, and the side air inlet mode rises oil smoke and just directly is forced to absorb by air inlet when also having little time to spread in in-plant installation; During fan operation, air-flow in exhaust fume collecting hood (2) cavity and the air-flow outside the exhaust fume collecting hood (2) can form negative pressuren zone because of the change of air pressure in the space of certain limit around the kitchen range top, oil smoke is tightly surrounded, and oil smoke can't be spread.These characteristics has determined side air inlet formula oil extracting machine shown in Figure 2 to have the ability of powerful absorption oil smoke.But not enough is: because air inlet is near the pot face, the installation site is lower, when a large amount of oil smoke produce, and ceaselessly stir the pot in food the time, can accelerate the rising and the diffusion velocity of soot gas, and the rate of climb is greater than the speed that spreads to the left and right, though most oil smoke are absorbed by in-plant air inlet, but the encirclement that a small amount of faster oil smoke of rising and diffusion still can break through negative pressuren zone, escape from air inlet top and left and right sides direction, it is not thorough that oil smoke is absorbed, and the kitchen pollution problem fails thoroughly to solve.
