Description

흡기 및 배기 일체형 환기팬{VENTILATION FAN INTEGRATED WITH INTAKE AND EXHAUST AIR}VENTILATION FAN INTEGRATED WITH INTAKE AND EXHAUST AIR}

본 발명은 하나의 구동수단(모터 등)에 의해 흡기(吸氣)와 배기(排氣)가 동시에 이루어지는 흡기 및 배기 일체형 환기팬(Ventilation Fan)에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an intake and exhaust integrated ventilation fan in which intake and exhaust are simultaneously performed by one drive means (motor or the like).

일반적으로 건축물의 통풍(通風)이나 환기(換氣)가 제 기능을 발휘하기 위해서는 흡입되는 공기와 배출되는 공기의 흐름이 원활해야 한다.
In general, in order for the building's ventilation and ventilation to function properly, the flow of intaken and discharged air must be smooth.

현재 주택이나 업소 등의 건축물들은 기밀성이 높아 열효율 측면에서는 매우 우수하지만 충분한 통풍이나 환기를 의식적으로 행하지 않으면 안 되는 구조이다.
At present, buildings and houses are very good in terms of thermal efficiency due to their high airtightness, but they must be consciously provided with sufficient ventilation and ventilation.

예컨대, 이들 건축물에 사용 중인 조리용 환기장치의 경우, 오염된 공기를 배출하는 배기팬(排氣 Fan)만 구비되어 있어서 통풍이나 환기가 불충분(미비)하므로 연소 및 조리과정에서 발생되는 각종 유해가스, 냄새, 수증기, 연기, 먼지 등이 실내공기와 혼합 및 잔류하면서 사람의 건강을 헤치는 문제점이 있으며, 또한 조리기기의 연소에 의해 실내공기가 다량 소모되며 심한 경우 질식하는 등의 여러 문제점이 있다.
For example, in the case of cooking ventilation devices used in these buildings, only the exhaust fan for exhausting the polluted air is provided with insufficient ventilation or ventilation, so various harmful gases generated during combustion and cooking processes are insufficient. There is a problem that the smell, water vapor, smoke, dust and the like mixed with the indoor air and damages the health of the person, and also consumes a large amount of indoor air by the combustion of the cooking appliance, and there are various problems such as choking.

일부 국가에서는 가스레인지가 작동할 때, 출입문에 달려 있는 조그마한 창을 열어 두어 조리시에 발생하는 유해가스의 배출을 유도하고 있지만, 효율이 낮을 뿐 아니라, 그 마저도 임시적인 조치에 불과하다.
In some countries, when the stove is operating, small windows open at the doors are open to induce the release of harmful gases during cooking, but the efficiency is low and even temporary measures.
