KITCHEN VENTILATION SYSTEM CAPABLE OF EFFICIENT VENTILATION THROUGH A MAIN EXHAUST AND AUXILIARY EXHAUST OF A RANGE HOOD

摘要

PURPOSE: A kitchen ventilation system is provided to improve ventilation efficiency by selectively operating a main exhaust and auxiliary exhaust through a range hood.;CONSTITUTION: A kitchen ventilation system comprises a range hood(10), a first exhaust duct(20), an inhalation hole(30), a second exhaust duct(40), an exhaust unit(50), and an exhaust pipe(60). The range hood discharges the indoor air contaminants from the kitchen to outside. The first exhaust duct guides the contaminants, flowing through the range hood, in order to exhaust to outdoor. The inhalation hole discharges the contaminants which does not be discharged through the range hood, to outside from the kitchen. The second exhaust duct guides the contaminants, flowing through the inhalation hole, in order to exhaust to outdoor. The exhaust unit comprises a plurality of exhaust fan. The exhaust fan is connected to the first and second exhaust duct and compulsorily sucks the contaminants of the kitchen in the first and second exhaust ducts through the range hood and inhalation hole. The exhaust pipe is connected to the exhaust unit and discharges the contaminants, inhaled in the first and second exhaust ducts, to outdoor.;COPYRIGHT KIPO 2011
