Embodiment 1

[0028] 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.

[0029] 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.

[0030] The range hood provided in this embodiment adopts the smoke detection method of the range hood as follows: the light emitter emits infrared light or laser toward the oil fume area, and detects the infrared light or laser light that comes from the light emitter and passes through the oil fume area The light intensity or its change trend can be used to ju...

Embodiment 2

[0045] Such as figure 2 As shown, the range hood that automatically adjusts the wind speed provided in this embodiment is provided with accommodating holes 3 on the side walls, 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 reflected by the oil fume area.

[0046] 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.

[0047] The range hood provided in this embodiment adopts a method for detecting smoke from the range hood. The light emitter emits infrared light or laser light toward the oil fume area, and detects the reflected infrared light or laser light from the light emitter. Intensity or its change trend can be used to judge the smoke concentration and / or the change trend of smoke concentration in the oil fume area.

Embodiment 3

[0062] Such as image 3 As shown, the range hood with automatic wind speed adjustment provided in this embodiment is provided with three accommodation holes 3 on the side wall of the smoke collection chamber, and one light emitter 1 and two light receivers 2 are respectively accommodated in the accommodation holes 3 . The light receiver can receive the light emitted by the light emitter and reflected by the fume area of ​​the range hood.

[0063] 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.

[0064] The range hood provided in this embodiment adopts the smoke detection method of the range hood as follows: the light emitter emits infrared light or laser light toward the oil fume area, and two light receivers respectively detect the smoke from the light emitter and pass through the oil fume area. The intensity of reflected infrared light or laser light is compar...

Abstract

The invention discloses a range hood capable of regulating the wind speed automatically. A light emitter and a light receiver are arranged on the side wall of the range hood. The light emitter can emit pulse light towards a lampblack collection cavity of the range hood. The light receiver can receive the light which is emitted by the light emitter and penetrates through a lampblack area or is reflected by the lampblack area. According to the range hood capable of regulating the wind speed automatically, the wind speed of a draught fan can be regulated 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...
