Abstract

The invention relates to a flow pushing mechanism and method for an extractor hood. The flow pushing mechanism for the extractor hood comprises an air feeding device which comprises draught fans and air guiding pipes, and is characterized in that the number of the air guiding pipes is three, and the number of the draught fans is two; the first end port of the first air guiding pipe and the first end port of the second air guiding pipe are both connected with an air outlet channel of the first draught fan; the first end port of the third air guiding pipe and the second end port of the second air guiding pipe are both connected with an air outlet channel of the second draught fan; the second end port of the first air guiding pipe is a first air outlet; the second end port of the third air guiding pipe is a third air outlet; a second air outlet is formed in the middle portion of the second air guiding pipe; the first air outlet, the second air outlet and the third air outlet all face an air suction port of the extractor good; and the three air outlets are located in three side faces of a smoke collection hood of the extractor hood correspondingly. The flow pushing mechanism for the extractor hood can guide floating cooking fume to flow to the air suction port of the extractor hood and push the cooking fume to be gathered towards the air suction port, and the suction and discharging effects of the cooking fume are greatly improved.

Description

technical field [0001] The present invention relates to a range hood, and specifically refers to a flow pushing mechanism and a flow pushing method for a range hood. Background technique [0002] In order to further improve the suction and exhaust effect of oil fume and compensate for the floating oil fume caused by air flow disturbance, people set up an air curtain structure on the range hood to form an air curtain around the fume collecting hood to block the floating oil fume and improve the oil fume suction and exhaust effect. [0003] The utility model patent with authorized notification number CN2814186Y discloses a "healthy range hood capable of generating three-sided air curtains and preventing oil fumes from escaping", a healthy range hood capable of generating three-sided air curtains and preventing oil fumes from escaping. It has an exhaust pipe, a main fan assembly, a top plate, and a smoke collection hood installed under the top plate. It is characterized in that...
