The utility model provides a range hood 1.

Referring to fig. 1 to 3, in the embodiment of the present invention, a range hood 1 includes a range hood main body 2 and an air purifying device 3.

The cigarette machine main part 2 hangs usually and hangs in the cooking utensils top of kitchen environment usually, be formed with the wind channel of discharging fume (not marking) in the cigarette machine main part 2, the wind channel of discharging fume has the inlet flue (not marking) with kitchen environment intercommunication and with the exhaust port (not marking) of outdoor intercommunication, the cigarette machine main part 2 still is provided with smoke exhaust fan, under smoke exhaust fan's drive, the oil smoke in the kitchen environment gets into the wind channel of discharging fume through advancing the mouth of fume to discharge to outdoor by the exhaust port, cigarette machine main part 2 possesses traditional range hood's function from this.

The air purification device 3 is installed outside the cigarette machine main body 2, the air purification device 3 comprises a shell 31, a filter piece 32, a purification fan 33 and a humidification assembly 34, a purification air channel (not marked) is formed in the shell 31, an air inlet 31a and an air outlet 31b communicated with the purification air channel are formed in the shell 31, the humidification assembly 34 and the filter piece 32 are arranged in the purification air channel, and the purification fan 33 is used for driving air flow to flow from the air inlet 31a to the air outlet 31b through the humidification assembly 34. Wherein, the purification wind channel among the air purification device 3 and the wind channel of discharging fume in the cigarette machine main part 2 are independent each other, air intake 31a and air outlet 31b on the purification wind channel all communicate with the indoor environment in kitchen, and in the range hood 1 operation process of this application, the produced oil smoke of culinary art process is most discharged to outdoor through the wind channel of discharging fume, and the indoor space that the kitchen was located can be escaped to the fractional part oil smoke. The small part of the oil smoke can be further removed through the synergistic effect of the purifying air ducts in the air purifying device 3, so that the pollution of the oil smoke to the air environment and the damage to the health of people in the indoor environment of the kitchen are further reduced.

In the kitchen environment, the temperature of the indoor environment, particularly the temperature of the position close to the range hood 1, is relatively high in the cooking process. Therefore, the moisture in the air can be rapidly evaporated due to high temperature, so that the air blown to the human body after the range hood 1 is processed by the air purification device 3 is relatively dry, a person who is in the environment for a long time for cooking can feel dry and uncomfortable, and even in the environment for a long time, the mouth and the tongue of the person are dry and lack of water. For this reason, the present application further humidifies the air flow in the clean air duct through the humidifying assembly 34, so that the humidity of the air blown to the cook is increased, thereby improving the kitchen indoor environment.

That is, the range hood 1 according to the technical scheme of the present invention can discharge most of the oil smoke outdoors through the cooperative work of the air purification device 3 and the range hood main body 2, and a small part of the oil smoke is purified and removed through the air purification device 3, so as to further reduce the oil smoke content in the kitchen environment, thereby reducing the damage of the oil smoke to the human health, and the humidification component 34 is arranged in the air purification device 3, so that the humidification component 34 increases the humidity of the air flow blown out by the air purification device 3, thereby improving the high temperature dry kitchen environment formed in the cooking process, and further improving the human comfort of the cook.

During cooking, edible oil and food undergo a series of chemical reactions such as oxidation, cracking and polymerization at high temperature, a large amount of organic smoke is evaporated, and partial decomposition products are emitted into air in the form of oil mist to form oil smoke. The oil fume includes both edible oil and its heating decomposition or cracking product and also includes the physical and chemical reaction product of protein, polymer compound and various seasoning matters in food, and is one kind of matter containing gas, liquid and solid. Generally, the Particulate Matter emission (Particulate Matter Emissions) consisting of liquid and solid in the soot emission is abbreviated as PME, and the Volatile Organic Compounds emission (Volatile Organic Compounds Emissions) is abbreviated as VOCs. The oil smoke is composed of the above two substances, wherein the VOCs can be regarded as the smell of the oil smoke. In one embodiment, in order to realize the basic oil smoke filtering function, the filtering element 32 of the present application includes an HEPA filter (high efficiency air filter) and an activated carbon filter, the HEPA filter may include PP filter paper (polypropylene filter paper), glass fiber, PTFE filter paper (polytetrafluoroethylene filter paper), nanofiber, melt-blown polyester non-woven fabric, etc., and has the characteristics of large dust holding capacity and high filtering precision, the filtering efficiency for oil smoke particles may exceed 90%, and the filter may be processed into a desired size and shape according to the model, the activated carbon filter is mainly used for filtering volatile organic compounds (odor) in the oil smoke, the material may include activated carbon fiber, activated carbon particles, etc., and the adopted activated carbon material may be coconut shell, fruit shell, coal carbon, etc., the specific surface area of such material is large, or the adopted activated carbon material may be a molecular sieve material, the material has good adsorption effect.
