The fan discharges air through the first air outlet pipeline, according to the Bernoulli equation, the pressure at the position where the air speed in the pipeline is fast is small, namely negative pressure relative to other positions is formed at the outlet of the first air outlet pipeline, under the action of the negative pressure, oil smoke below the flue enters a smoke product under the traction of wind power, and then is discharged outdoors; in the oil smoke extraction process, the blades of the fan are not in direct contact with oil smoke, so that the pollution of the blades of the fan can not be caused.

Further, the power of the fan is adjustable.

Further, the fans include a high power fan 4 and a low power fan 5.

The requirements under different conditions can be met by adjusting the power of the fan or setting the fan with large and small power, for example, a large amount of oil smoke is generated during cooking or frying, and at the moment, the large amount of oil smoke needs to be quickly discharged outdoors, so that a high-power fan can be adopted or the output power of the fan is set to be high power; when the soup is stewed or cooked, the generated oil smoke is less, energy is wasted if high power is adopted, and in order to achieve the purpose of energy conservation, a low-power fan can be used or the output power of the fan is set to be low power.

Further, air inlet holes 2-1-1 are formed in the portions, close to the top plate 2-2, of the side plates 2-1.

The combustion hot gas rises to the suspended ceiling or the roof of the kitchen, and a part of residual oil smoke and air at the position cannot be convected with the air below, so that the oil smoke and the combustion hot gas at the suspended ceiling or the roof are accumulated, and the kitchen is polluted; in order to discharge the part of the oil smoke and the combustion hot gas, the air inlet holes 2-1-1 are formed in the parts, close to the top plate 2-2, of the side plates 2-1, and the oil smoke and the combustion hot gas on the top of the kitchen are sucked into the case through the fan and enter the air inlet of the fan, so that the indoor temperature is reduced, and the air circulation of the kitchen is promoted. The air inlet holes 2-1-1 have a certain width in the vertical direction so as to ensure the oil smoke absorption effect.
