An oil filter type range hood

Abstract

The invention discloses an oil filter type range hood. The oil filter type range hood comprises a fan outer cover, an exhaust fume collecting hood, a filter screen and a rectifying plate arranged on the exhaust fume collecting hood and below the filter screen, wherein a fan is arranged in the fan outer cover, the range hood is characterized in that a bubble generator is arranged at an air inlet region between the rectifying plate and the filter screen, suction air current produced by the fan is matched with the bubble generator to product bubble blowing to the internal region between the rectifying plate and the filter screen. Compared with the prior art, the oil filter type range hood has the advantages that the bubble generator is arranged at an air inlet region between the rectifying plate and the filter screen, the fan can drive the airflow below the exhaust fume collecting hood to upward flow after bypassing the rectifying plate when being started, the airflow is blown to the bubble generator to enable the bubble generator to produce bubble, the contact area with the fume is increased by using the large surface area of the bubble, and the oil filter effect of the range hood is promoted by using the soluble performance of liquid soap to the grease under the condition of using the soap bubble.

Description

technical field [0001] The invention relates to kitchen electrical equipment, in particular to an oil filter type range hood Background technique [0002] The range hood is an electrical device widely used in the kitchen, which is used to exhaust the oily fumes generated during the cooking process of the stove. In the process of oil fume exhaust, the oil fume is separated from the oil and gas at the filter screen of the range hood, so as to avoid the oily gas directly discharged into the atmosphere and cause pollution. net, and drip into the oil cup below the strainer after diversion. [0003] The oil filtering effect is an important indicator of the range hood. At present, many range hoods improve the oil filtering effect by improving the filter structure. For example, the "rotary filter screen for range hood" disclosed in the Chinese invention patent application whose application number is 201110170306.8 (application publication number is CN 102331019 A), the rotary filt...

AI Technical Summary

Problems solved by technology

Although, the filter screen can rotate slowly when the range hood is working, so that the oil and gas can fully contact with the filter screen, increase the collision probability to separate and filter the oil fume, improve the oil and gas separation effect, and reduce the oil droplets with smaller diameters It is difficult to drop on the filter screen, thereby improving the cleanliness of the filter screen, but it will bring about a rapid increase in resistance and a decrease in air volume.
