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

Abstract

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 the lowest cost by applying fans with positive pressure to output characteristics to range hoods for improved vertical installation in apartment dwellings to remove polluted air Air is exhausted from the kitchen hoods on each floor to the ventilation system at the top of the exhaust pipe. The kitchen ventilation system of the present invention includes an exhaust duct 100, which is located on one side of the apartment house; and a range hood 200, which is located in the kitchen on each floor, and includes a fan 210, which has a positive pressure to output characteristic for The ambient air is collected and the collected air is discharged to the exhaust duct 100 . According to the present invention, noise can be reduced, and economic efficiency and ventilation performance can also be improved by maximizing polluted air discharge efficiency at the lowest cost.

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...

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
