KITCHEN VENTILATION SYSTEM WITH TURBULENT AIR FLOW

摘要

PURPOSE: A kitchen ventilation system is provided to achieve a comfort environment by preventing the noise caused due to the operation of the exhaust fan, air supply fan and the blower from being transferred to other area like kitchen or living room. CONSTITUTION: A kitchen ventilation system comprises a range(20) installed in a kitchen; a hood(22) mounted over the range; an exhaust pipe(24) arranged at the top of the hood so as to guide the contamination substances generated during cooking operation to the outside; an exhaust fan(26) mounted at the top of the exhaust pipe so as to compulsorily discharge the contamination substances generated during cooking operation; a filter(28) coupled to be attachable/detachable to/from the lower end of the exhaust pip and which has a central portion bent upwardly so that both ends of the filter are directed downward; an air supply pipe(32) having an air supply fan(30) mounted at a fixed end of the air supply pipe so as to compulsorily take the outdoor air, and a free end arranged in front of the hood; and a blower(34) connected to turbulent flow generating holes(36) formed at both edges of the range so as to generate a turbulent air flow.
