Extractor hood with sterilization and deodorization functions

Abstract

The invention relates to an extractor hood with sterilization and deodorization functions. The extractor hood comprises a machine case and a draught fan arranged in the machine case, and further comprises a shield cover, an ultraviolet lamp and an oil scraping part. The shield cover comprises a cover body made of a transparent material and can rotate relative to the ultraviolet lamp. The oil scraping part can scrape the surface of the cover body in the rotating direction of the cover body when the shield cover rotates. Moreover, the shield cover has at least two states according to different rotating angles. In the first state, the shield cover can block the ultraviolet lamp from contamination of lampblack. In the second state, the ultraviolet lamp is at least partially exposed outside theshield cover. The exterior of the extractor hood with the sterilization and deodorization functions can be treated through ultraviolet light emitted by the ultraviolet lamp and ozone generated in theprocess of decomposing air by the ultraviolet lamp to achieve the purposes of deodorizing and purifying the internal environment of the extractor hood. The influence of the lampblack on the ultraviolet lamp is avoided through the shield cover. Lampblack particles are prevented from adhering to the surface of an ultraviolet lamp tube so that the ultraviolet lamp can keep good sterilization and deodorization effects.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood with the functions of sterilization and deodorization. Background technique [0002] At present, the range hoods on the market, whether they are top-suction or near-suction machines, are generally of the external exhaust type without sterilization and purification functions. Oil stains, and lead to the growth of bacteria and microorganisms or produce odors, which will adversely affect the kitchen environment and even the health of users. [0003] In recent years, some range hoods with bactericidal function have appeared on the market. This type of range hood generally installs ultraviolet lamps in the body of the range hood, uses ultraviolet rays for disinfection and sterilization, and decomposes oxygen molecules in the air through ultraviolet beams. , produce free oxygen, free oxygen combines with oxygen molecules to produce ozone, and ozone has a strong oxidation effect...

AI Technical Summary

Problems solved by technology

[0005] In this patent, the ultraviolet lamp is set in the body of the range hood. Since it is in the fume environment for a long time, after a period of use, the surface of the lamp tube is easy to accumulate oil stains, resulting in a decrease in its disinfection and sterilization performance.

Although the rinsing device is set near the ultraviolet lamp in the above-mentioned patent, so the rinsing device can rinse the surface of the ultraviolet lamp to a certain extent, but there are still the following problems: the adhesion of oil fume particles on the surface of the ultraviolet lamp is very low. Strong, the cleaning effect of the washing device is not good; the maintenance of the washing device is troublesome, and it will be blocked by oil fume; installing the washing device inside the range hood will increase the volume of the range hood, etc.
