(54) Range hood capable of resisting draft


(57) A range hood capable of resisting draft is provided above a counter on the top of which an air-generation device is located. The range hood comprises an air-extraction hood that has a bottom provided with an elongate air-extraction slot for drawing air upwards. Besides, an air blow groove is provided in front of the elongate air-extraction slot for blowing air downwards. A long left upright plate and a long right upright plate are respectively provided below the left and right lateral surfaces of the air-extraction hood. Thereby, when the elongate air-extraction slot draws in air, an oblique airflow is formed. Besides, the long left and right upright plates are able to hinder the draft coming from lateral sides, so as to protect the oblique airflow structure. Consequently, an intact upwards-flowing airflow is formed to exhaust soot and harmful gases.
