Foam filtration and interception type range hood

Abstract

The invention provides a foam filtration and interception type range hood. The foam filtration and interception type range hood comprises a housing (1), a fan (5) and a smoke collecting hood (2); thefan (5) is arranged inside the housing (1); the smoke collecting hood (2) is arranged at an air inlet at the lower end of the housing (1) and comprises a smoke gathering region; the foam filtration and interception type range hood is characterized by further comprising a foam generator (6); the foam generator (6) comprises a liquid storage box (61), a bracket (62) and a rotating part; the rotatingpart (63) comprises an impeller at the inner circle and a foaming net (621) which is positioned at the periphery; the impeller can rotate along ne direction under the effect of a rising air force; and the foaming net (621) is partially positioned inside a liquid supply end opening of the liquid storage box (61). The overall rotating part is arranged over against the air inlet, so the covered airinlet area is large, the amount of generated foam is large, and oily smoke purification and filtration effects are played; the fan works, air flows rise, and then the rotating part can freely rotate along one direction without being driven by independent power, so the installation cost is low.

Description

technical field [0001] The invention relates to a range hood and belongs to the technical field of kitchen utensils. Background technique [0002] The range hood is an electrical device widely used in the kitchen to exhaust the oily fume generated during the cooking process of the stove. Before the fume is exhausted into the flue, the grease is separated through the filter screen installed in the range hood, so as to avoid the pollution caused by the oily gas directly discharged into the atmosphere. The existing mechanical filter screen mainly separates and filters the oil fume by increasing the contact area with the oil fume and increasing the probability of collision, but it brings the unfavorable results of a rapid increase in resistance and a decrease in air volume. [0003] In order to enhance the filtering effect of the range hood, there are some improved schemes, one of which is to use the large surface area ratio of soap bubbles and the easy solubility of soap liqui...

AI Technical Summary

Problems solved by technology

The rotation of the bubbler needs to overcome the resistance of other foaming liquids such as soap liquid, and it is difficult to realize the rotation with the incoming wind under the position of weak wind force

Limited by the space of the installation location, the amount of foaming cannot be very large, and the filtering effect of oil fume is limited
