Soot filter and extractor hood with soot filter

Abstract

The invention relates to a soot filter. The soot filter comprises a pipe, filter units are arranged across the pipe at equal intervals along the length direction of the pipe, the filter unit comprisesat least two filters at an interval along the width direction of the pipe, at least one end of the filter is fixed to the inner wall of the pipe, the adjacent filters form a filtering channel for flowing of gas. The invention also relates to an extractor hood with the soot filter. Gas of a fan can enter a purification chamber through the soot filter so that the gas in the purification chamber isfiltered and the pollution and damage of an ozonator are avoided. The soot filter can disturb ozone gas, premix the ozone gas, drive the ozone gas to pass through a gas outlet and enter an inner chamber, an inner chamber of the fan and an air outlet chamber so that the circulation in the extractor hood is formed, a dynamic balance state in the extractor hood is kept and the ozone concentration tobe treated in the extractor hood is uniform and is in a dynamic balance state.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to an oil fume filtering device and a range hood applied with the device. Background technique [0002] The range hood is used to discharge the flue gas outside. After a period of use, the inside of the range hood tends to accumulate oil, such as the smoke collection hood and fan of the range hood. The long-term accumulation of oil stains will easily lead to the breeding of bacteria inside the range hood, and lead to the generation of peculiar smell, which will affect the kitchen environment and the health of users. [0003] Traditional range hoods generally do not have the function of sterilization and purification. Ozone is a gas with strong bactericidal ability, and its bactericidal ability is about 3000 times that of chlorine gas. The Chinese invention patent that the application number is 201110258991.X (the application publication number is CN 102966987 A) discloses a kind of smoke...

AI Technical Summary

Problems solved by technology

[0004] The device in the above-mentioned patent is equipped with an ozone generator, and uses the ozone generator to generate ozone to sterilize and purify the inside of the range hood. However, the ozone generator has been in the fume environment inside the range hood for a long time, and the adhesion of a large amount of oil or dust will make the ozone The circuit of the generator is short-circuited and the ozone generator is damaged, thus affecting its sterilization and purification effect

Furthermore, the specific gravity of ozone molecules is greater than that of air, so the ozone generated by the ozone generator will not automatically disperse, resulting in uneven ozone concentration inside the range hood, that is, the concentration of ozone near the ozone generator is higher, while the concentration of ozone far away from the ozone generator The concentration of ozone is low, and the molecules of ozone are extremely unstable and easy to decompose, which further exacerbates the uneven concentration of ozone inside the range hood, and the effective sterilization and deodorization of ozone requires a certain concentration and a certain period of time.

It can be seen that the structure of the existing range hood with an ozone generator has limited the full play of the sterilization and deodorization function of ozone, and needs further improvement
