Embodiment 1

[0046] A range hood linked with an air purification device, such as figure 1 As shown, there is a hood main body, a polycyclic aromatic hydrocarbon detection device that calculates the current concentration of polycyclic aromatic hydrocarbons in the cooking area and obtains an environmental health level signal according to the detected temperature in the cooking area and the size of the fumes in the cooking area, and is connected with external air purification. The device is signally connected to and controls the linkage control device of the external air purification device, and the polycyclic aromatic hydrocarbon detection device is electrically connected to the linkage control device and the main body of the hood respectively.

[0047]The polycyclic aromatic hydrocarbon detection device detects the concentration of polycyclic aromatic hydrocarbons in the current cooking area to obtain the environmental health level signal and transmits it to the linkage control device. The l...

Embodiment 2

[0107] A range hood linked with an air purifying device, other features are the same as the first embodiment, the difference is that the linkage control device in this embodiment is wirelessly connected to the external air purifying device.

[0108] The wireless signal connection in the present invention is a WiFi signal connection, a Bluetooth signal connection, an NFC signal connection, or a ZIGBee signal connection, etc. The specific selection depends on the actual situation. This embodiment is specifically WiFi signal connection.

[0109] Compared with Embodiment 1, the wireless signal connection in this embodiment is more flexible.

Embodiment 3

[0111] A range hood linked with an air purifying device, other features are the same as in Embodiment 1, the difference is: the calculation formula of the calculation module is formula (I),

[0112] C 多环芳烃 =0.05κ+0.05λ+0.33κλ+475.1 Formula (I),

[0113] where C 多环芳烃 : is the total concentration of polycyclic aromatic hydrocarbons 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.

[0114] 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 :.

[0115] 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 :.

[0116] where C (2-3) is the concentration of bicyclic polycyclic aromatic hydrocarbons and tricyclic polycyclic aromatic hydrocarbons, C (4) is the concentration of tetracyclic polycyclic aromatic hydrocarbons, C (5-6) is the concentration of five-ring polycyclic aromatic hydrocarbons and six-...

Abstract

The invention provides a kitchen ventilator linked with an air purifying device. The kitchen ventilator is provided with a ventilator main body, a polycyclic aromatic hydrocarbon detecting device anda linkage control device, wherein the polycyclic aromatic hydrocarbon detecting device is used for obtaining the current concentration of polycyclic aromatic hydrocarbon in a cooking region and an environment health grade signal of the cooling region by means of calculation according to the detected temperature of the cooking region and the quantity of oily smoke in the cooking region; the linkagecontrol device is in signal connection with an external air purifying device and is used for controlling the external air purifying device; and the polycyclic aromatic hydrocarbon detecting device iscorrespondingly electrically connected with the linkage control device and the ventilator main body. The kitchen ventilator can be used for detecting the concentration of the polycyclic aromatic hydrocarbon in the current cooking region and can be linked with the external air purifying device so as to purify the air containing the polycyclic aromatic hydrocarbon, and thus the health of a user canbe guaranteed. The invention further provides a linkage selection control method which realizes linkage selection between the kitchen ventilator and the air purifying device by virtue of three stepsso as to screen out the air purifying device of which the optimization grade value is maximum, and thus an optimal air purification effect can be achieved.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood linked with an air purification device and a linkage selection control method. Background technique [0002] In modern life, many families produce a lot of oil fumes during cooking. Studies have shown that cooking oil fume has complex components, has certain inhalation toxicity, immunotoxicity and mutagenicity, and has certain harm to human health. Fume gas includes polycyclic aromatic hydrocarbons, and a considerable part of polycyclic aromatic hydrocarbons 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 cooking fumes in the current cooking environment, nor can it be linked with an air purification device to reduce the concentration of polycyclic aromatic hydrocarbons in the current cooking environment, which greatly limits the range hood. intelligent dev...
