Description
Technical Field
The utility model relates to a new fan in kitchen, in particular to split type new fan in kitchen, the oxygenating pressure boost and the air purification technique in kitchen negative pressure oxygen deficiency space that in particular to kitchen smoke ventilator caused belong to air quality control technical field.
Background
The indoor air quality standard is implemented in China for decades, people have deeper and deeper knowledge on the indoor air quality, and the improvement of the indoor air quality is an urgent requirement of people. The source of indoor air pollution is mainly in kitchens and toilets, where kitchens are the most severe places where oxygen is consumed, and polluted gases and fumes are produced. The use of smoke ventilator does not solve the air pollution state in the kitchen completely, and produced negative pressure and outdoor polluted gas to room secondary pollution, specifically embodies:
1) generating negative pressure: the better the room is sealed, the more severe the negative pressure is generated. The range hood only has the function of exhausting oil smoke in a kitchen, is a one-way flow ventilator, can cause serious negative pressure in the kitchen, so that exhaust is seriously influenced, the oil smoke in the kitchen cannot be exhausted, fresh air in the kitchen with better sealing cannot enter, the range hood with larger air volume can generate more serious negative pressure, the serious negative pressure obstructs the effect of oil smoke extraction, the pollution degree of outdoor pollution to the kitchen is increased, the heart rate of people can be reduced, and serious negative influence on the health of people can be caused; at present, the air volume of the range hood in the market is rapidly increased from 7m3 to 30m3, the sealing degree of a room is higher and higher, and the air draft speed is far less than the air leakage and air inlet speed of a kitchen; the investigation shows that the pressure in the kitchen is reduced from 1013hPa to 600hPa by using the high-power range hood, the pressure of the Pirasa is low, and severe altitude reaction can be generated when the range hood is operated under the low negative pressure for a long time.
2) Oxygen deprivation: the fire for heating food can completely consume oxygen in limited air in a kitchen and simultaneously generate pollutants such as carbon dioxide, carbon monoxide, smoke and the like; when the maximum negative pressure is reached in the kitchen, the air volume is only 50% of the nominal air volume, no purified fresh air enters the kitchen, oxygen consumed for combustion supporting cannot be supplemented, exhausted oxygen cannot be increased almost, carbon monoxide toxic gas is generated during combustion of the stove, and generated carbon monoxide, carbon dioxide and other pollution gases cannot be completely discharged, so that the health of people in the kitchen is affected.
3) The polluted gas in the kitchen is serious: when dishes and fried foods are fried, serious oil fume pollution is generated, energy is consumed for heating the foods, and a large amount of heat is generated; particularly in summer, high heat pollution is generated by heating food, polluted gas in a kitchen cannot be purified, and oil smoke and high heat generated in the kitchen cannot be completely removed due to the generation of negative pressure; the negative pressure can reduce the discharge of oil smoke and increase the inflow of outdoor polluted air; the hood removes only the polluted air from the cooking bench and the part near the cooking bench, but the polluted air around the operating cook on one side of the cooking bench cannot be removed.
According to the analysis, when the range hood is adopted, the oil smoke in the kitchen is difficult to exhaust even if a high-power fan is used when the kitchen is sealed, and the oxygen deficiency, the polluted gas and the high heat in the kitchen cannot be treated; poorly sealed kitchens also increase the ingress of contaminated air. Aiming at the above situation, the kitchen air can be really treated only by introducing the treated fresh air to play the role of the smoke exhaust ventilator; the kitchen is the biggest pollution source in house room, and the air pollution who has only administered the kitchen can improve the pollution state of people's house environment, for the secondary pollution that solves smoke ventilator to produce, introduces purification treatment's new trend equipment, becomes the subject that the new trend trade must be studied.
