Extractor hood with sterilization and deodorization functions

Abstract

The invention relates to an extractor hood with sterilization and deodorization functions. The extractor hood includes a machine shell and a draught fan arranged in the machine shell. The extractor hood with sterilization and deodorization functions is characterized in that the extractor hood with sterilization and deodorization functions further includes a sterilization and deodorization assembly. The sterilization and deodorization assembly includes an ultraviolet radiator. A first end of the ultraviolet radiator is arranged in the machine shell through an arranging seat, and a second end can rotate relative to the draught fan taking the first end as the center in the driving of a driving assembly. According to the extractor hood with sterilization and deodorization functions, ultraviolet light emitted by the ultraviolet radiator and ozone produced by decomposition of air by the ultraviolet light can be used to conduct treatment on the interior of the extractor hood, and the purposesof peculiar smell removing and purification of inner environment of the extractor hood are achieved. In addition, the illuminating angle and range of the ultraviolet radiator can be effectively changed, so that better effects of peculiar smell removing and purification are obtained.

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

In this patent, the ultraviolet lamp is set in the range hood body. 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, 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.
