Abstract

The invention relates to a range hood capable of performing lampblack and hearth linkage according to working environment. The range hood comprises a range hood body, a temperature sensing module, animage acquiring device and a polycyclic aromatic hydrocarbon detection device, wherein the range hood body can be linked with external cookers and adjust operation according to the working environment; the temperature sensing module is used for detecting temperature in a cooking region; the image acquiring device is used for analyzing lampblack images of the cooking region, and obtaining the magnitude of produced lampblack in a real-time manner; the polycyclic aromatic hydrocarbon detection device is used for performing calculation according to the temperature of the detected cooking region and the concentration of lampblack in the cooking region so as to obtain current polycyclic aromatic hydrocarbon of the cooking region; and the temperature sensing module, the image acquiring device andthe polycyclic aromatic hydrocarbon detection device are separately and electrically connected with the range hood body. According to the range hood capable of performing lampblack and hearth linkageaccording to working environment disclosed by the invention, the current concentration of the polycyclic aromatic hydrocarbon of the cooking region can be obtained through calculating the magnitude of the lampblack in the cooking region; besides, according to the magnitude of the lampblack, the temperature in the cooking region and the concentration of the polycyclic aromatic hydrocarbon, a fan and a lampblack separating device are automatically adjusted, so that lampblack and harmful gas are quickly pumped from a kitchen; the range hood can be linked with the external cookers, generation ofthe harmful gas and the lampblack can be effectively reduced, and the health guarantee of a user is greatly improved.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood that performs linkage with a range hood according to the working environment. Background technique [0002] In modern life, many families produce a lot of cooking fume. Studies have shown that cooking fume has complex components, has certain inhalation toxicity, immunotoxicity and mutagenicity, and has certain hazards to human health. Oily fumes include polycyclic aromatic hydrocarbons, and quite a few of them are carcinogenic, such as benzo[α]pyrene. The range hood in the prior art cannot automatically identify the concentration of polycyclic aromatic hydrocarbons in the range hood in the current cooking environment. At the same time, the range hood cannot be linked to the cooker according to the concentration of polycyclic aromatic hydrocarbons, which greatly limits the intelligent development of the range hood. [0003] Therefore, aiming at the deficiencies of the pr...
