Self-checking system and self-checking method for range hood capable of regulating wind speed automatically

Abstract

The invention discloses a self-checking system for a range hood capable of regulating the wind speed automatically. The self-checking system for the range hood capable of regulating the wind speed automatically comprises a light emitting module, a light receiving module and a judgment module. The light emitting module can emit working light towards a lampblack collection cavity of the range hood. The light receiving module can receive the working light which is emitted by the light emitting module, penetrates through a lampblack area and reflected by the lampblack area. The judgment module obtains the signal value of the working light emitted by the light emitting module and the signal value of the working light received by the light receiving module and conducts equipment fault judgment according to the obtained signal values. The invention further discloses a self-checking method for the range hood capable of regulating the wind speed automatically. According to the range hood capable of regulating the wind speed automatically, it can be guaranteed that the range hood is in a good working state through self-checking, 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 self-inspection system and a self-inspection method for an automatic speed-regulating range hood. 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. [0004] For range hoods that can automatically adjust the...
