Embodiment 1

[0050] A kitchen ambient air quality prompting device, such as figure 1 As shown, there is a temperature sensing module for detecting the temperature of the cooking area, an image acquisition module for analyzing the cooking area fume image and obtaining the size of the cooking fume in real time, calculated according to the detected temperature of the cooking area and the size of the cooking fume Current PAH detection module and reminder module in the cooking area.

[0051] The temperature sensing module, the image acquisition module and the polycyclic aromatic hydrocarbon detection module are respectively electrically connected to the prompting module.

[0052] The temperature sensing module senses the temperature of the cooking area to obtain a temperature output signal and transmits it to the PAH detection module. The image acquisition module collects the oil fume image in the cooking area to obtain the oil fume output signal and transmits it to the PAH detection module. Th...

Embodiment 2

[0107] A kitchen environment air quality prompting device, other features are the same as in Embodiment 1, the difference is: the calculation formula of the polycyclic aromatic hydrocarbon detection module is formula (I),

[0108] C 多环芳烃 =0.05κ+0.05λ+0.33κλ+475.1 Formula (I),

[0109] where C 多环芳烃 is the total concentration of PAH gas in the cooking area, κ is the output data of the temperature sensing module, and λ is the output data of the image acquisition module.

[0110] When κ∈(0℃, 200℃), λ∈(0,300), C (2-3) =70%C 多环芳烃 ,C (4) = 20%C 多环芳烃 ,C (5-6) = 10%C 多环芳烃 .

[0111] When κ∈(200℃, 240℃), λ∈(300,500), C (2-3) = 60%C 多环芳烃 ,C (4) = 25%C 多环芳烃 ,C (5-6) = 15%C 多环芳烃 .

[0112] where C (2-3) is the concentration of bicyclic PAHs and tricyclic PAHs, C (4) is the concentration of tetracyclic PAHs, C (5-6) is the concentration of five-ring PAHs and six-ring PAHs.

[0113] For example, when κ is 100°C and λ is 100, directly substitute the data values ​​of κ and λ...

Embodiment 3

[0116] A kitchen environment air quality prompting device, other features are the same as in Embodiment 1, the difference is: the calculation formula of the polycyclic aromatic hydrocarbon detection module is formula (II),

[0117] C 多环芳烃 =0.05κ 0.98 +0.05λ 1.05 +0.33κλ+469.5 Formula (II).

[0118] where C 多环芳烃 is the total concentration of PAH gas in the cooking area, κ is the output data of the temperature sensing module, and λ is the output data of the image acquisition module.

Abstract

The invention relates to a kitchen environment air quality prompt device. The kitchen environment air quality prompt device is provided with a temperature sensing module, an image acquisition module,a polycyclic aromatic hydrocarbon detection module and a prompt module; the temperature sensing module is used for detecting the temperature of a cooking area; the image acquisition module is used foranalyzing a cooking area oil smoke image and obtaining the amount of generated oil smoke in real time; the polycyclic aromatic hydrocarbon detection module is used for obtaining the polycyclic aromatic hydrocarbon concentration in the current cooking area according to the detected temperature of the cooking area and the amount of oil smoke in the cooking area; and the temperature sensing module,the image acquisition module and the polycyclic aromatic hydrocarbon detection module are electrically connected with the prompt module respectively. The kitchen environment air quality prompt devicecan calculate the polycyclic aromatic hydrocarbon concentration in the current cooking area according to the temperature of the cooking area and the oil smoke condition of the cooking area, and send aprompt signal; the prompt device can give an alarm in time; therefore, a user can know the harmful gas condition in the current environment at the first moment, and make corresponding protection; andthe health protection of users is greatly improved.

Description

technical field [0001] The invention relates to the field of kitchen ambient air detection, in particular to a kitchen ambient air quality prompting 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, which greatly limits the intelligent development of the range hood. [0003] Therefore aiming at the deficiencies in the prior art, it is necessary to provide a kitchen environment air quality prompting device to solve the deficiencies in the prior art.
