Abstract

The present invention relates to a kitchen ventilation system to which a fan having a positive pressure-to-output characteristic is applied. More particularly, the present invention relates to a system for maximizing efficiency of exhausting polluted air at minimum costs by applying a fan having a positive pressure-to-output characteristic to a hood, to improve a ventilation system which is installed vertically in an apartment house to discharge polluted air from kitchen hoods on respective floors to the top of an exhaust duct. The kitchen ventilation system of the present invention comprises an exhaust duct 100 provided at one side of an apartment house, and a hood 200 which is provided in the kitchen on each floor and includes a fan 210 having a positive pressure-to-output characteristic to collect surrounding air and discharge the collected air to the exhaust duct 100. According to the present invention, noise can be reduced and economical efficiency and ventilation performance can also be improved by maximizing efficiency of exhausting polluted air at minimum costs.

Description

TECHNICAL FIELD

[0001] The present invention relates to a kitchen ventilation system to which a fan having a positive pressure-to-output characteristic is applied. More particularly, the present invention relates to a system for maximizing efficiency of exhausting polluted air at minimum costs by applying a fan having a positive pressure-to-output characteristic to a hood, to improve a ventilation system which is installed vertically in an apartment house to discharge polluted air from kitchen hoods in respective floors to the top of an exhaust duct, thereby reducing noise and improving economical efficiency and ventilation performance. BACKGROUND ART

[0002] In general, a major source of polluting room air in an apartment house is a variety of harmful materials such as heat, smell and oil vapor, which are produced when a person cooks in the kitchen. To discharge the harmful materials produced in the kitchen to the outside, a hood is installed in the kitchen, and an exhaust duct is a...
