Range hood

Abstract

The invention discloses a range hood. The range hood comprises an exhaust fume collecting hood, an air inlet is formed in the exhaust fume collecting hood, an upwards-concave exhaust fume collecting cavity is formed in the exhaust fume collecting hood, a rectifying plate is arranged in the exhaust fume collecting cavity and located below the air inlet, the front portion of the rectifying plate isclamped with the exhaust fume collecting hood through a clamping structure, and the rear portion of the rectifying plate is hinged to the exhaust fume collecting hood; and the clamping structure comprises clamping claws arranged on the two sides of the front portion of the upper surface of the rectifying plate and buckles arranged on the exhaust fume collecting hood and corresponding to the clamping claws. The range hood is characterized in that each buckle comprises a clamping part which can be connected with the corresponding clamping claw in a clamped mode and can drive the corresponding clamping claw to ascend and descend, and therefore the rectifying plate can rotate relative to the exhaust fume collecting hood. The front part of the rectifying plate is arranged to be rotatable, so that the rectifying plate inclines forwards to increase an air inlet area when the range hood works, the exhaust fume suction effect and the effective air volume are improved, the rectifying plate inclines backwards when the range hood does not work, the rectifying plate can incline backwards to guide oil, the rectifying plate can be hidden to improve the attractiveness, and the user experience is improved.

Description

technical field [0001] The invention relates to kitchen equipment, in particular to a range hood. Background technique [0002] The range hood has become one of the indispensable kitchen appliances in modern families, and it is used to exhaust the oil fume produced during the cooking process of the stove. Generally, range hoods include top-suction and side-suction types, and top-suction range hoods are more and more widely used due to their neatness, lightness, and small footprint. [0003] The top-suction range hood usually includes a fume collecting hood, a fan casing positioned on the fume collecting hood, and a centrifugal fan is installed in the fan casing. For example, a range hood disclosed in Chinese patent application No. 201310111398.1 includes a fan for generating air flow, an inner panel on the inner surface of the exhaust hood, and a filter detachably installed on the air inlet of the inner panel, And the rectification plate on the upstream side of the air flo...

Problems solved by technology

[0004] In the existing range hood, it can be seen from the above that the rectifying plate needs to be set at a backward inclination angle to guide the oil to the oil cup, and in actual use, it is more beneficial to inhale the oil fume. Structural design can only ensure greater air volume and oil suction effect by allowing the rectifier plate to extend out of the overall smoke hood under the premise of ensuring the backward tilt angle and using oil guide
