Description
Technical Field
The invention relates to a range hood, in particular to a range hood with an air purification function.
Background
During cooking, edible oil forms a mixture of 3 organic forms, namely oil smoke, in gas state, liquid state and solid state under high temperature. Depending on the morphology, the mixture of liquid and solid particles, called oil mist, is divided into settleable and inhalable particles; the gaseous part is Volatile Organic Compounds (VOCs), gaseous pollutants in the household kitchen and also combustion exhaust gases. The particle size of the settleable particles in the oil fume is mainly distributed between 10 and 400um, and the particles can be settled on the ground and the surfaces of other objects under the action of self gravity and the interaction between the particles, so that the air environment of a kitchen cannot be permanently polluted. Generally, particles with the particle size of below 10um are called inhalable particles, namely PM10, the particles are not easy to settle and always float in the air environment of a kitchen, and the particles can be inhaled by a human body and deposited on the respiratory tract, the alveolus and the like to cause diseases and harm the health of the human body. The smaller the particle size of the particles, the deeper the site of entry into the respiratory tract. Particles with a diameter of less than or equal to 2.5um among respirable particles are called respirable lung particles, i.e., PM2.5, and compared with particles with a particle size of more than 2.5um and less than 10um, PM2.5 is more harmful to human body, and VOCs can also form PM2.5 through chemical reaction in air.
The pollution of cooking oil smoke and the harm effect on human health become a very important indoor environmental problem. The range hood is used as an electric appliance for purifying the kitchen environment, exhaust gas burnt by a stove and oil smoke generated in the cooking process can be quickly pumped away and exhausted outdoors, so that the pollution to the air environment in the kitchen is reduced, but it is difficult to completely exhaust the exhaust gas, the oil smoke and peculiar smell only through the range hood, because escape parts always exist in the pumping process, the exhaust gas, the oil smoke and the peculiar smell which cannot be exhausted stay in the kitchen, the health of people is threatened, and the original air quality in the household kitchen cannot be improved by using the range hood. Meanwhile, the demand of the current consumers for the open kitchen of the home is strong, but in the cooking process, once the kitchen is opened, the air environment of the dining room and the living room is affected despite the use of the range hood.
In recent years, as the public attaches importance to the air quality and health, the market for air purifier products is rapidly expanding. However, no air purifier product specially adapted for household kitchen exists so far, mainly because the air environment of household kitchen is special, compared with the common indoor air environment, oil drop particles are increased in the kitchen air environment, decomposition products (VOCs) and combustion waste gases (carbon monoxide, nitrogen oxides and the like) of edible oil and food which are chemically changed in the heating process are more humid, and under such indoor air environment, the common air purifier cannot complete the task.
If a common air purifier is placed in an air environment of a household kitchen for use, the air purifier using the granular activated carbon filter screen can be contacted with incoming air firstly, oil drop particles (belonging to liquid granules) exist in the air, the air is more humid, in the using process, the activated carbon granules can absorb a lot of moisture and easily generate peculiar smell, and meanwhile, the oil drops directly contacted with the granular activated carbon filter screen can be adhered to the surfaces of the granules to block adsorption holes, so that after the air purifier is used for a short period of time, the effects of adsorbing harmful gas and removing the peculiar smell can be greatly reduced or even completely lost. For an air purifier using an activated carbon fiber filter screen, the HEPA high-efficiency filter screen can firstly contact incoming air, and can intercept a large amount of oil drop particles and solid particles in the air and absorb moisture in the air. Because the fiber yarn made of the HEPA high-efficiency filter screen is not oleophilic and not hydrophilic (the intercepted oil drop particles and the absorbed water stay on the surface of the fiber), the oil drop particles in the air can be coated on the fiber yarn, and in addition, the intercepted solid particles are added, under the condition, the fiber yarn and the fiber yarn can be quickly glued and adhered together, after the HEPA high-efficiency filter screen is used for a short period of time, the wind resistance of the HEPA high-efficiency filter screen can become large, and the normal use is seriously influenced; the interior of the filter screen becomes moist due to the fact that a large amount of moisture is absorbed, and therefore a convenient environment is provided for the bacteria breeding in a large amount. In addition, for the photolysis link of a common air purifier, the catalytic layer is extremely afraid of oil, and if the oil cannot be removed through the previous links of the photolysis, the catalytic layer can be covered by oil stains to cause the photolysis to lose the effect. Therefore, if a general air purifier is desired to be used in a kitchen air environment, the above problems are unavoidable, the service life of the air purifier is greatly shortened due to the particularity of the use environment, the normal use of the air purifier is seriously affected and limited, and the air purifier itself becomes a pollution source after being used for a short time, so that a solution is urgently needed to improve the existing kitchen air pollution problem.
