Abstract

The invention relates to a kitchen fume type polycyclic aromatic hydrocarbon detection device assembled on a kitchen fixing part. The polycyclic aromatic hydrocarbon detection device calculates the current polycyclic aromatic hydrocarbon concentration of a cooking area according to detected temperature and fume size of the cooking area. The polycyclic aromatic hydrocarbon detection device is provided with a temperature sensing module, an image acquisition module and a calculation module, wherein the temperature sensing module is used for detecting the temperature of the cooking area; the imageacquisition module is used for analyzing fume images of the cooking area and obtaining the fume size in real time; the calculation module is used for calculating the polycyclic aromatic hydrocarbon concentration of the current cooking area; the temperature sensing module and the image acquisition module are electrically connected with the calculation module separately. The polycyclic aromatic hydrocarbon detection device is also provided with a wind speed control module, a prompt module and a fire control module, and the wind speed of an external kitchen ventilator and fire of an external stove are automatically adjusted according to the current environmental health grade, so that the polycyclic aromatic hydrocarbon concentration in the current environment is reduced, and a user is reminded to pay attention to protection at the same time.

Description

technical field [0001] The invention relates to the field of kitchen oil fume detection, in particular to a kitchen oil fume polycyclic aromatic hydrocarbon detection device. 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. [0003] Therefore, aiming at the deficiencies of the prior art, it is necessary to provide a kitchen fume type polycyclic aromatic hydrocarbon detection device to solve the deficiencies of the prior art. Contents of the invention [0004] One of the objectives...
