Range hood

Abstract

The invention discloses a range hood. The range hood comprises an exhaust fume collecting hood, a box body arranged above the exhaust fume collecting hood and an exhaust fume gathering assembly, wherein the exhaust fume collecting hood comprises an exhaust fume collecting cavity and an air inlet communicating with the exhaust fume collecting cavity and the box body, and the exhaust fume collectingcavity and the air inlet form a main air inlet channel; and the range hood is characterized in that auxiliary air inlet channels communicating with the main air inlet channel are formed in the position, at the left side and the right side of the air inlet, of the interior of the exhaust fume collecting hood, the exhaust fume gathering assembly comprises two exhaust fume collecting plates which can move in the left-right direction and all the exhaust fume collecting plate can be located in a first position and a second position, in the first position, the exhaust fume collecting plates are located in the corresponding auxiliary air inlet channels, so that the auxiliary air inlet channels are separated from the main air inlet channel, and in the second position, the exhaust fume collectingplates extend out of the auxiliary air inlet channels in the direction away from each other, so that the auxiliary air inlet channels communicate with the exterior of the range hood and the main air inlet channel. According to the range hood, the auxiliary air inlet channels are formed in the position, at the two sides of the air inlet, of the interior of the exhaust fume collecting hood so that escaping exhaust fume can enter the box body from the auxiliary air inlet channels as much as possible, the escape of the exhaust fume is greatly reduced, and the suction effect of the exhaust fume isimproved.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Chinese cooking will produce a lot of oily fumes. In order to keep the kitchen environment clean and the human body healthy, range hoods have become one of the essential equipment in modern home kitchens. 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 collection hood, a fan casing positioned on the fume collection hood, and a volute, an impeller and a motor for driving the impeller are installed in the fan casing. Oily fume generated during the cooking process is collected in the fume collecting hood, passes through an air inlet connected with the fume collecting hood, and then is discharged outside through an air duct. [0004] Common stoves a...

Problems solved by technology

However, since the fume on the left and right sides is ready to escape, it has already left the negative pressure capture area of ​​the fan system. Although the smoke deflector can play a temporary role in collecting smoke, it is still not enough to capture enough fume to escape.
