Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0022] Such as figure 1 As shown, the range hood with automatic wind speed adjustment provided by this embodiment is provided with accommodating holes 3 on the left and right side walls of the smoke collecting cavity, and the light emitter 1 and the light receiver 2 are respectively accommodated in the accommodating holes 3 . The light receiver can receive the light emitted by the light emitter and passing through the fume area of ​​the range hood.

[0023] The light emitter can be an infrared light emitter or a laser emitter. Correspondingly, the light receiver can be an infrared light receiver, or a laser receiver.

[0024] The range hood provided in this embodiment adopts the...

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...
