Smoke exhauster

Abstract

The invention relates to a smoke exhauster. The smoke exhauster comprises a machine enclosure, a draught fan arranged in the machine enclosure, a shield cover and an auxiliary functional device arranged in the machine enclosure. The shield cover can rotate relative to the auxiliary functional device, and according to the different rotation angles, the shield cover at least has two states that under the first state, the shield cover can block the auxiliary functional device to avoid pollution of oil smoke, under the second state, the auxiliary functional device is at least partially exposed outof the shield cover, and the functions of the auxiliary functional device can be developed. According to the smoke exhauster, the shield cover can rotate, and can block the auxiliary functional device, therefore the auxiliary functional device can be prevented from being affected by the oil smoke, oil smoke particles are prevented from adhering to the surface of the auxiliary functional device, therefore a good using state of the auxiliary functional device can be maintained, and the service life of the smoke exhauster is prolonged.

Description

technical field [0001] The invention relates to the field of kitchen appliances, in particular to a range hood. Background technique [0002] At present, the range hoods on the market, whether it is a top-suction type or a near-suction type, are generally of the external exhaust type and have no sterilization and purification function. After a long time of use, the hoods and fans inside the range hood are easy to gather Oil stains, and lead to the growth of bacteria and microorganisms or produce peculiar smell, which will adversely affect the kitchen environment and even the health of users. [0003] In recent years, some range hoods that add auxiliary functions to traditional range hoods have appeared on the market, such as range hoods with sterilization function, range hoods with sensors (such as odor sensors, etc.) added inside Wait. Among them, the range hood with sterilization function generally installs ultraviolet lamps in the body of the range hood, uses ultraviole...

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.
