The fine grid openings have good blocking effect on filtering tiny (less than 100 mu m) oil liquid and oil smoke particles, and intercept the tiny (less than 100 mu m) oil liquid and oil smoke particles.
The dynamic control method of the oil smoke dynamic blocking system mainly comprises the following steps: firstly, the rotary power of the oil smoke dynamic blocking disc is driven by air flow generated by the operation of a fan, and the rotating speed of the oil smoke dynamic blocking disc can be dynamically changed along with the air quantity of the fan. When more oil smoke is generated in cooking, the range hood needs to be adjusted to a high gear, and the air flow speed in the volute is increased along with the increase of the rotating speed of the impeller in the fan according to a dynamic pressure equationF=n Fan with fan body As can be seen from the formulas E and S, the driving force acting on the blades of the kinetic energy recovery device increases exponentially, the torque generated by the kinetic energy recovery device increases accordingly, and the recovered torque is transmitted to the dynamic barrier disc through the transmission shaft 112; therefore, the rotating speed of the dynamic blocking disc is correspondingly increased along with the increase of the gear of the smoke machine, and the blocking force for the oil smoke is improved; calculated to be 20m 3 When the smoke machine with the air quantity per minute works at the maximum gear, the dynamic shielding disc can be accelerated to more than 800r/min only by a few seconds, and most of grease liquid drops and part of PM can be shielded by matching with the dynamic blocking disc with a thin opening 10 PM (particulate matter) 2.5 。
When less oil smoke is generated in the cooking process, the range hood only needs to work at a lower gear, the airflow velocity in the volute is reduced, the rotating speed of the dynamic blocking disc is correspondingly reduced due to wind resistance and component friction resistance, the suction resistance to the smoke is reduced, the efficiency of the range hood to the smoke suction is improved, and meanwhile, the noise and abrasion of a mechanical mechanism during working are reduced. According to the test result and formula, the air quantity is 20m 3 The/min range can be at least 400m at the lowest gear 3 And about/min, the cooking device can meet the requirements of common low-oil-smoke cooking. Therefore, the invention can realize the control of the range according to the different working ranges of the range without any additional power source and electric control deviceAnd (5) dynamically adjusting the fume interception force.
