Range hood with auxiliary air inlet channel

The invention provides a range hood with an auxiliary air inlet channel. An oil filtering plate is installed on the front face of a cooking fume collecting cover. Main air inlets are formed in the oil filtering plate, and the oil filtering plate of the range hood is obliquely arranged towards the rear lower side from top to bottom. Auxiliary air inlets are formed in at least one of an area adjacent to the upper side edge of the oil filtering plate and an area adjacent to the lower side edge of the oil filtering plate. The auxiliary air inlets are in a long bar shape and are transversely through. Due to the fact that the auxiliary air inlets of the range hood are continuous and uninterrupted air inlet channels, the defect that gate-hole-shaped main air inlets are interrupted and not continuous can be overcome, and the air inlet area can be enlarged and a cooking fume path can be changed through the auxiliary air inlets. In addition, the included angle alpha between the oil filtering plate and the horizontal plane is designed to be larger than or equal to 18 degrees and smaller than or equal to 30 degrees, and under the condition that negative-pressure covering angles are the same, the negative-pressure covering area of a cooking bench is larger; and furthermore, after the auxiliary air inlets are arranged, the phenomenon that negative pressure is weakened and cooking fume escapes due to the fact that the inclination angle of a cooking fume guide plate relative to the horizontal plane becomes smaller can be effectively avoided, and therefore the cooking fume absorbing effect is improved.
