Abstract

The invention discloses an automatic wind speed regulating system for a range hood. The automatic wind speed regulating system for the range hood comprises a lampblack detecting module and a draught fan regulating module. The lampblack detecting module is used for detecting the result of the effect of a lampblack area on light and sending the detection result to the draught fan regulating module or is used for speculating the lampblack concentration information of the lampblack area by means of the detection result and sending a speculation result to the draught fan regulating module. The draught fan regulating module is used for giving out a regulation command to a draught fan according to the detection result or the speculation result sent from the lampblack detecting module. The invention further discloses an automatic wind speed regulating method for the range hood. According the automatic wind speed regulating system for the range hood, the wind speed of the draught fan of the range hood 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 system and method for automatically adjusting the wind speed of a 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. Contents of the invention [0004] The object of the present invention is to...
