Air curtain kitchen fumes ventilator

Abstract

The present invention provides one kind of kitchen fume sucking wind curtain method and corresponding kitchen fume exhauster. Narrow slot is formed in the edge of at least one side of the kitchen fume collecting hood to spray air flow forming wind curtain inwards deviating to the work area, with the inwards deviating airflow being turbulent airflow formed with the so-called arced inwards airflow or laminar airflow formed with multiple nozzle thin airflow. Meanwhile, the exhauster of the kitchen fume exhauster makes the kitchen fume rolled into the exhauster. The kitchen fume exhauster can form separating wind curtain between the cook and the fume while exhausting kitchen fume effectively.

Description

Technical field [0001] The present invention relates to a method for sucking and discharging oil fume by an air curtain and a range hood adopting the method. Specifically, the present invention is an air curtain formed by using laminar, turbulent or divergent airflow towards a working area, and is compatible with the prior art The suction power of the conventional exhaust fan entrains the oil fume to be sucked and discharged, and forms an air curtain between the oil fume and the user, so that the oil fume does not enter the user’s area due to the divergence of the airflow, and is used to achieve the Method of extractor hood. Background technique [0002] Cooking food will produce a lot of oily fume. The absorption of oily fume by the human body will harm your health. The earlier range hoods are generally passive range hoods, that is, an exhaust fan is set in a certain position in the range hood shell, and the bottom center of the fume hood The suction port is set, and the oily fu...

[0005] However, the air blown out from the air supply port will gradually weaken the effect of the air curtain during the descent process, and diverge as the distance away from the air supply port 7 increases, see Figure 2, without the suction of the exhaust fan, it is usually a trapezoidal cross-section Divergent air curtain ( Figure 2a ) or drop-shaped cross-section air curtain ( Figure 2b ), under the action of the suction of the exhaust fan 5, the trapezoidal cross-section divergent air curtain or the water-drop-shaped cross-section air curtain deflects to the bottom center of the smoke collecting hood (such as Figure 2c , 2d shown), even so, the oily fumes generated during cooking will also diverge outside the suction range of the fume collection hood, and this kind of air curtain is obviously affected by the outside world. The air curtain airflow not only cannot assist the extraction of oil fume, but may cause more floating oil fume

[0006] In the prior art, there are also disclosed air outlets that can change the angle, but this increases the complexity of the structure, improves the processing difficulty and manufacturing cost
