Oil fume track guiding device and extractor hood applying device

Abstract

The invention discloses an oil fume track guiding device. The oil fume track guiding device is characterized by comprising a fan, and the fan can suck front air to generate negative pressure so as tointegrally guide oil fume rising upwards from the front side to the rear side; and the fan comprises a first air inlet which faces forwards. The invention further discloses an extractor hood applyingthe oil fume track guiding device. Compared with the prior art, the oil fume track guiding device has the advantages that the oil fume track guiding device utilizes the fan to suck air to generate a certain degree of negative pressure so as to form the form effect that the oil fume rising upwards is integrally guided to the rear side, and therefore the oil fume rising path track is changed; when the oil fume track guiding device is arranged below an extractor hood body, the smoke gathering range of the extractor hood can be reduced, and the sense of repression of a user during cooking can be effectively relieved; the head collision probability of a top suction type extractor hood is reduced; and a fume barrier (a fume baffle plate) of a side suction type extractor hood can be omitted, andthus the problems of sight blocking, head collision and the like of the fume barrier are effectively avoided.

Description

technical field [0001] The invention relates to an oil fume purification device, in particular to an oil fume trajectory guide device, and a range hood applied with the device. Background technique [0002] Range hoods have become one of the indispensable kitchen appliances in modern homes. The range hood uses the principle of fluid dynamics to work. The centrifugal fan installed inside the range hood sucks and discharges the oil fume, and uses the filter screen 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. 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.
