Embodiment 1

[0071] A range hood controlled according to the working environment, such as figure 1 As shown, it is equipped with a main body of the hood that can adjust the operation according to the working environment, and calculates the current concentration of polycyclic aromatic hydrocarbons in the cooking area based on the detected temperature in the cooking area and the size of the oil fume in the cooking area. Separate oil fume separator, fan and oil fume separator are assembled on the main body of the hood. The environment detection device is electrically connected with the main body of the hood, the fan and the oil fume separator respectively.

[0072] The temperature in the cooking area of ​​the present invention is preferably to detect the temperature of the kitchen utensils, and may also be to detect the temperature of the air in the cooking area, the temperature of the oil fume, or the temperature of the cooker, and the specific implementation method depends on the actual sit...

Embodiment 2

[0127] A range hood controlled according to the working environment, other features are the same as in Embodiment 1, the difference is that the calculation formula of the calculation module is formula (I),

[0128] C 多环芳烃 =0.05κ+0.05λ+0.33κλ+475.1 Formula (I),

[0129] 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.

[0130] 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) = 15%C 多环芳烃 .

[0131] 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 .

[0132] 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.

[0133] For example, when κ is 100°C and λ is 100, directly substitute the data values ​​of κ and λ into the formul...

Embodiment 3

[0136] A range hood controlled according to the working environment, other features are the same as in Embodiment 1, the difference is that the calculation formula of the calculation module is formula (II),

[0137] C 多环芳烃 =0.05κ 0.98 +0.05λ 1.05 +0.33κλ+469.5 Formula (II).

[0138] 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.

[0139] 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 .

Abstract

The invention relates to a range hood controlled according to working environment. The range hood is provided with a range hood body capable of adjusting operation according to the working environment, an environment detection device, a fan and an oil smoke separator for separating oil smoke particles, wherein the environment detection device is used for calculating to obtain current polycyclic aromatic hydrocarbon concentration in a cooking area according to the detected temperature in the cooking area and the oil smoke size in the cooking area; and the fan and the oil smoke separator are assembled on the range hood body. The range hood controlled according to the working environment can calculate the current polycyclic aromatic hydrocarbon concentration in the cooking area according to the oil smoke size in the cooking area, and the fan and the oil smoke separation device can be automatically adjusted according to the oil smoke size, the temperature in the cooking area and the polycyclic aromatic hydrocarbon concentration, so that the oil smoke and harmful gases are rapidly pumped out of a kitchen; and the range hood can be linked with an external cooker, so that the generation of the harmful gases and oil smoke is effectively reduced, and the health protection of users is greatly improved.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood controlled 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, which greatly limits the intelligent development of the range hood. [0003] Therefore aiming at the deficiencies of the prior art, it is very necessary to provide a range hood controlled according to the working environment to solve the deficiencies of the prior art. Contents of the...
