Embodiment 1

[0043] An infrared temperature and vision collaborative detection cooking system, such as Figures 1 to 5 As shown, it is provided with an infrared temperature sensor 2 for detecting the temperature of the cooking area, a visual detection device for detecting the size of the oil fume in the current cooking area, and is used for calculating the concentration of polycyclic aromatic hydrocarbons according to the size and temperature of the oil fume and controlling the ventilation device 1 and heat generation. The control device controlled by the device 4, the ventilation device 1 for ventilation and the heat energy generating device 4 for cooking, the infrared temperature sensor 2 and the visual detection device are electrically connected with the control device respectively, and the control device is connected with the ventilation device 1 and the heat generation device respectively. 4 signal connections.

[0044] The infrared temperature sensor 2 senses and detects the temperat...

Embodiment 2

[0114] An infrared temperature and visual collaborative detection cooking system, other features are the same as embodiment 1, the difference is: the infrared temperature sensor 2 of the present invention is an intrusive infrared temperature sensor 2.

[0115] The intrusive infrared temperature sensor 2 of the present invention can be assembled on the external pot used in cooking, the pot rack of the heat energy generating device 4 and the external stove 5, and the specific assembly position is determined according to the actual situation. The intrusive infrared temperature sensor 2 of this embodiment is assembled on an external pot used in cooking.

[0116] Compared with Embodiment 1, the distance between the intrusive infrared temperature sensor 2 of this embodiment and the pan to be detected is closer, so the obtained detection data is more accurate.

Embodiment 3

[0118] An infrared temperature and visual collaborative detection cooking system, other features are the same as in embodiment 1, the difference is: the calculation formula of the control device is formula (Ⅲ),

[0119] C 多环芳烃 =0.05κ+0.05λ+0.33κλ+475.1...Formula (Ⅲ);

[0120] where C 多环芳烃 is the total concentration of polycyclic aromatic hydrocarbon gas in the cooking area, κ is the output data of the infrared temperature sensor 2, and λ is the output data of the visual detection device.

[0121] 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 .

[0122] 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) = 150%C 多环芳烃 .

[0123] 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.

[0124] For example, when κ is 100°C and λ is 100, directly substitute ...

Description

technical field [0001] The invention relates to the field of cooking equipment, in particular to an infrared temperature and visual collaborative detection cooking system. Background technique [0002] In modern life, many families produce a lot of oily fumes containing harmful substances during cooking. Studies have shown that cooking fume has complex components, has certain inhalation toxicity, immunotoxicity and mutagenicity, and has certain hazards to human health. There are many harmful substances in the fume gas, such as polycyclic aromatic hydrocarbons. Among them, quite a few PAHs are carcinogenic, such as benzo[α]pyrene. The prior art household control system cannot automatically identify the polycyclic aromatic hydrocarbons in the cooking fumes in the current cooking environment. [0003] Therefore, aiming at the deficiencies of the prior art, it is necessary to provide an infrared temperature and visual collaborative detection cooking system to solve the defici...
