Range hood capable of regulating wind speed automatically

Abstract

The invention discloses a range hood capable of regulating the wind speed automatically. A light emitter and a light receiver are correspondingly arranged on the side wall of the range hood. The light emitter can emit light towards a lampblack collection cavity of the range hood. The light receiver comprises a light receiver probe which faces the lampblack collection cavity of the range hood. A light shield device extends forwards from at least part of the periphery of the light receiver probe. According to the range hood capable of regulating the wind speed automatically, the wind speed of a draught fan can be adjusted automatically, operation is convenient, and energy saving is achieved while contamination caused by kitchen lampblack is fully prevented.

Description

technical field [0001] The invention relates to a range hood which can automatically adjust the wind speed. Background technique [0002] The composition of kitchen fumes is very complex, mainly including water, aldehydes, ketones, alcohols, etc., including volatile nitrosamines, heterocyclic amines and other known mutagenic and carcinogenic substances, as well as tar, carbon monoxide, and carbon dioxide. It is not only harmful to human health, but also pollutes the sanitary environment of the kitchen, so it must be removed in time. [0003] The wind speed of the traditional range hood needs to be adjusted manually, which is not scientific and accurate enough, and the extraction of oil fume does not meet the health requirements, and it is often inconvenient due to forgetting to turn on the switch of the range hood or needing to adjust the range hood during the cooking process. Contents of the invention [0004] The object of the present invention is to provide a range hoo...
