Lampblack track guiding device and extractor hood applying same

Abstract

The invention discloses a lampblack track guiding device, which is characterized by comprising a pipeline, an air duct extending left and right is formed in the pipeline, a first air inlet is formed in the front side of the pipeline, and the air duct is in fluid communication with the first air inlet; and a fan which can blow airflow into the air duct of the pipeline to generate negative pressureon the front side of the pipeline so as to guide the whole lampblack rising from the front side to the rear side. The invention further discloses an extractor hood applying the lampblack track guide device. Compared with the prior art, the lampblack track guiding device provided by the invention has the advantages that the lampblack track guiding device utilizes the fan to blow high-speed airflowinto the air duct, so that a certain degree of negative pressure is generated on the front side of the air duct, the form effect of integrally guiding the upward-rising lampblack to the rear side is formed, and the lampblack rising path track is changed.

Description

technical field [0001] The invention relates to a cooking fume purifying device, in particular to a cooking fume trajectory guiding device and a range hood using the device. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern families. The range hood uses the principle of fluid dynamics to work, sucks and exhausts the range hood through a centrifugal fan installed inside the range hood, and uses a filter to filter some grease particles. The centrifugal fan includes a volute, an impeller installed in the volute and a motor that drives the impeller to rotate. When the impeller rotates, a negative pressure suction is generated in the center of the fan, and the oil fume under the range hood is sucked into the fan, and after being accelerated by the fan, it is collected by the volute and guided out of the room. At present, common range hoods on the market include top suction and side suction. [0003] The top-suction rang...

AI Technical Summary

Problems solved by technology

Generally, the oil fume in the cooking pot will go through the process of rising upward and bursting after it is generated. If there is no smoke collecting hood or smoke screen (smoke baffle) in a large area above to collect the smoke, a large amount of oil fume will escape, resulting in Poor smoke effect

[0006] It can be seen from the above that the existence of the existing range hood makes the body of the range hood smaller and the effect of collecting smoke cannot be taken into account at the same time.
