Kitchen ventilation system with fan having positive pressure-to-output characteristic applied thereto

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 employing a fan with a positive pressure-to-output characteristic. More specifically, the present invention relates to a system for maximizing the efficiency of polluted air discharge at minimum cost by applying fans with positive pressure to output Air is exhausted from the kitchen range hoods on each floor to the ventilation system at the top of the exhaust pipe, which reduces noise and improves economic efficiency and ventilation performance. Background technique [0002] Generally speaking, the main sources of indoor air pollution in apartment houses are various harmful substances such as heat, odor and oil vapor, which are produced during cooking in the kitchen. In order to discharge harmful substances generated in the kitchen to the outside, a range hood needs to be installed in the kitchen, and an exhaust pipe is formed vertically on one side of the building to communicate with the k...

AI Technical Summary

Problems solved by technology

[0011] In the case of traditional kitchen ventilation systems, there are multiple pressure sensors that measure the air pressure at various heights in the exhaust pipe to control the power output of the fans according to these heights, but there is a technical problem that the total manufacturing of traditional kitchen ventilation systems The cost is bound to be high because of the need to have multiple pressure sensors to measure the air pressure and a microprocessor to process the signals from the pressure sensors to control the fans
