Problems solved by technology

[0003] The range hoods in the prior art cannot automatically identify the concentration of polycyclic aromatic hydrocarbons in the fumes in the current cooking environment, nor can they distinguish the types of food materials used in current cooking, such as vegetable oil or animal oil, nor can they identify the concentration of polycyclic aromatic hydrocarbons in the current cooking environment according to the current air quality and current The types of cooking materials are adjusted by the range hood, and the existing range hood cannot store and compare data, which greatly limits the intelligent development of the range hood

Embodiment 1

[0052] A range hood that can classify the health level of oil products used and historical data, such as figure 1 As shown, it is characterized in that it is provided with a main body of the hood, an oil product identification device for identifying the cooking oil currently being cooked, a harmful substance detection device, and is used for storing and comparing the detection data of the harmful substance detection device to reduce calculations. The load and the data storage device for improving calculation accuracy, the oil identification device are respectively electrically connected with the harmful substance detection device and the main body of the hood, and the harmful substance detection device is respectively electrically connected with the data storage device and the hood main body.

[0053] The oil product identification device acquires the edible oil currently used for cooking to obtain an oil product signal and sends the oil product signal to the harmful substance ...

Embodiment 2

[0134] A range hood that can classify the health level of used oil products and historical data, such as figure 2 As shown, other features are the same as in Embodiment 1, the difference is that the oil product identification device of this embodiment is a passive oil product that extracts the edible oil product information purchased by the user from the image collection and household equipment or obtains the edible oil product information from the database. Identify the device.

[0135] The passive oil product identification device is equipped with a passive input module to obtain edible oil product information through the camera capture method of the range hood, the method of capturing shopping information, or the indirect database and the method of comparing the temperature rise slope in the cooking area. The device is electrically connected to the main body of the cigarette machine.

[0136] The oil product identification device is also provided with a transceiver module...

Embodiment 3

[0143] A range hood capable of classifying health grades of used oil products and historical data, other features are the same as in Embodiment 1, the difference is that the calculation formula of the calculation module is formula (I),

[0144]

[0145] 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, λ is the output data of the image acquisition module, C is the output data of the particulate matter sensing component, C PM10 is the output data of the PM10 sensor, C PM2.5 is the output data of the PM2.5 sensor, C PM1.0 is the output data of the PM1.0 sensor, C PM0.1 is the output data of the PM0.1 sensor, C PMA is the output data of the PMA sensor, C VOC It is the output data of the VOC sensor.

Abstract

A range hood capable of performing health grading on a used oil product and historical data is capable of identifying an edible oil product kind for current cooking, a temperature in a cooking area, aparticle concentration in the cooking area, oil smoke magnitude, volatile organic compound concentration and polycyclic aromatic hydrocarbon concentration. Data storage can be performed, and existingdata can be compared with the historical data, thereby improving operation capability and operation accuracy of a harmful matter detecting device. The harmful matter detecting device of the range hood acquires a health grade signal of the current environment condition, and performs feedback of the health grade signal to a range hood body. Furthermore the range hood is provided with an air speed control module, a reminding module and a fire power control module. In the current health grade, the air speed and the fire power of an external furnace are automatically adjusted, thereby reducing theharmful matter in the current environment and reminding the user of protection.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a range hood capable of classifying health grades of used oil products and historical data. 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. At the same time, the types and contents of polycyclic aromatic hydrocarbons produced by different edible oils will be different. [0003] The range hoods in the prior art cannot automatically identify the concentration of polycyclic aromatic hydrocarbons in the fumes in the current cooking environment, nor can they distinguish the types of food materials used in current cooking, such as vegetable oil or animal oil, nor ca...
