Description
Technical field
The utility model is related to a kind of range hood, especially one kind can strengthen negative pressure at the top of smoke deflector and then improve oil suction
The range hood of cigarette ability.
Background technology
The Chinese invention of Patent No. ZL200910096759.3《A kind of range hood with smoke deflector》(Authorization Notice No.
For CN101514823B), which has body, exhaust fume collecting hood and smoke deflector, and exhaust fume collecting hood is equipped with air inlet, smoke deflector
(also known as smoke deflector) the face air inlet sets and maintains predetermined spacing with exhaust fume collecting hood, so that in smoke deflector and exhaust fume collecting hood two
Formed with holding the oil smoke passage that passes through of oil smoke between person, the smoke deflector in the patent is fixed setting, the position of its oil smoke passage
Put and size cannot be adjusted, there are following deficiency：
(1) this top-sucking kitchen ventilator integral installation highly determines that the pot of range hood distance generation oil smoke compares
Far, negative pressure loss is bigger；
(2) smoke deflector is located at exhaust fume collecting hood port and is designed with exhaust fume collecting hood split, very big after range hood installation smoke deflector
The depth of exhaust fume collecting hood is reduced in degree, often a degree of blasting fume phenomenon occurs not in time since oil smoke absorbs.
Utility model content
Technical problem to be solved in the utility model is the present situation for the prior art, there is provided one kind can be led by increase
