Extractor hood

Abstract

The invention discloses an extractor hood. The extractor hood comprises an exhaust fume collecting hood and an exhaust fume barrier which is arranged on the lower side of the exhaust fume collecting hood, wherein the exhaust fume barrier is detachably installed on the exhaust fume collecting hood; the exhaust fume collecting hood comprises an exhaust fume collecting hood body, a first shelving part at the bottom of the front side of the exhaust fume collecting hood body and a second shelving part at the bottom of the rear side of the exhaust fume collecting hood body. The first shelving part is bent backwards from the bottom of the front side of the exhaust fume collecting hood body, the second shelving part is bent forwards from the bottom of the rear side of the exhaust fume collecting hood body, and the front end and the rear end of the exhaust fume barrier are put on the first shelving part and the second shelving part respectively. The extractor hood further comprises a movement mechanism used for driving the exhaust fume barrier to move left and right, wherein the movement mechanism comprises a driving device and a toothed roller driven by the driving device, and the toothedroller extends front and back and is rotationally arranged on the second shelving part. At least two oil leakage holes are formed in the exhaust fume barrier, the oil leakage holes are distributed atintervals in left and right directions, and the toothed roller is meshed with the oil leakage holes and can drive the exhaust fume barrier to move.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a range hood. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. Generally, range hoods include top suction and side suction. The top-suction range hood is more and more widely used due to its advantages of neatness, lightness, and small footprint. 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. [0003] For example, the Chinese utility model patent with the application number of 201420478312.9 discloses a top-suction range hood with a smoke deflector, including a body, a smoke collecting hood and a smoke deflecting plate, wherein the smoke collecting hood is connected to the body, and a fan is arranged in the body , the air inlet is provided on...

AI Technical Summary

Problems solved by technology

[0004] At present, the top-suction range hoods with smoke baffles are common in the market, and the structural solutions for the installation and disassembly of the smoke baffle are relatively complicated.

On the one hand, it is not very convenient for users to disassemble and assemble, and on the other hand, the complex structure is not easy to clean oil stains; and usually the smoke baffle cannot be moved according to the actual concentration of oil fume, thus affecting the effect of oil suction
