Description

실내공기 조화용 환기구{ventilator of indoor air}Ventilator of indoor air

본 발명은 원통형으로 되어 아파트나 건물 천정에 부착되며 원통체 상단에 외부로부터 공급되는 공기공급관이 접속되는 공기공급구가 형성되고 원통체 하단에 공급된 외부 공기를 실내로 주입할 수 있게 배출구가 형성되며 배출구에 개폐판을 부착하여 원통체 상단공기공급구로 공급된 외부공기의 량을 조정하여 실내로 주입할 수 있도록 된 실내공기 조화용 환기구에 있어서, 외부로부터 공급되는 공기의량을 방의 크기에 갖추어 공급할 수 있도록 공기 공급구의 크기를 조정할 수 있게 구성하여 환기구로 들어오는 외부 공기량을 조정하고 이를 통해 해당 실내에 주입되는 공기량을 균형있게 조정할 수 있도록 구성한 것이다.The present invention is a cylindrical shape is attached to the ceiling of the apartment or building and the air supply port is connected to the air supply pipe supplied from the outside on the top of the cylindrical body and the discharge port is formed to inject the outside air supplied to the interior of the cylinder bottom It is a ventilator for indoor air conditioning that can be injected into the room by adjusting the amount of external air supplied to the upper air supply port of the cylindrical body by attaching an opening / closing plate to the exhaust port. It is configured to adjust the size of the air supply port so that it can be supplied to adjust the amount of external air entering the ventilation opening and through this to balance the amount of air injected into the room.

종래의 환기구는 원통체 상단에 형성된 공기공급구로 외부공기가 공급되는 공기 공급관이 접속되면 공급구 하단으로 형성된 배출구를 통해 공급된 공기가 실내에 주입되고 배출구에 장치된 개폐판을 열어서 실내로 공급되는 공기량을 조정할 수 있게 한 것이지만 환기구의 원통체로 들어오는 외부 공기량이 방의 크기와 무관하게 일률적으로 형성되어 있어서 방의 크기와 상관없이 공기 공급이 이루어저 배출구에 장치된 개폐판의 개방정도를 조정하여 실내에 주입되는 공기량을 조정하도록 하고 있기 때문에 개폐판과 개방부의 간격을 적게 하면 원통체로 공급된 공기와 배출되는 공기량의 공차가 커져서 공기저항이 커져 소음이 생기고 간격을 넓게 하면 개폐판이 개방부에서 밑으로 많이 내려오기 때문에 간격이 커져서 보기가 싫게 되는 결점이 있었다.Conventional vent is an air supply formed in the upper end of the cylindrical body when the air supply pipe is supplied to the outside air is supplied through the outlet formed through the outlet formed in the lower end of the air is injected into the room is supplied to the room by opening the opening and closing plate installed in the outlet Although the amount of air can be adjusted, the amount of external air coming into the cylinder of the ventilation port is uniformly formed regardless of the size of the room. Therefore, the air is supplied regardless of the size of the room. If the gap between the switchgear and the opening is reduced, the tolerance between the air supplied to the cylinder and the amount of discharged air is increased, so the air resistance increases, and the gap is widened. The drawback is that the gap is so large that you don't want to see it. It was.

본 발명은 상기와 같은 불균형에 의한 불편을 해소하기 위해 개발된 것이다.The present invention has been developed to solve the inconvenience caused by such an imbalance.

본 발명은 환기구의 원통체 상단에 형성되는 공기공급구의 크기를 환기하고져 하는 실내의 용적에 맞추어서 조정이 이루어질 수 있도록 공기 조정구를 장치하여 환기구로 공급되는 외부 공기량을 실내의 크기에 맞추어 공급할 수 있게 구성함으로써 외부에서 주입되는 공기공급량과 환기되는 공기량의 조화가 실내의 용적에 맞게 이루어져 균형잡힌 공기 조화가 이루어질 수 있게 환기구를 개선한 것이다.The present invention is configured to be able to supply the amount of external air supplied to the ventilation opening to the size of the room by the air adjusting device to adjust the size of the air supply port formed on the top of the cylindrical body of the ventilation opening to the volume of the room to be ventilated By doing so, the balance between the amount of air supplied from the outside and the amount of air to be ventilated is adapted to the volume of the room, thereby improving the ventilation opening to achieve balanced air conditioning.

이와 같이 된 본 발명은 환기구의 원통체(1a)상단에 형성된 공기공급구(1b)에 주입통기공의 크기를 조정하는 조정구(8)(80)가 장치되어 외부공기공급관(2)을 통해 환기구의 원통체(1a)로 주입되는 외부 공기량을 방의 크기에 맞추어서 공급할 수 있게 되므로 공기가 들어오는 단계에서 공급량의 균형이 이루어지게 되고 환기구로 들어온 외부 공기량의 범위 안에서 실내로 주입되는 공기공급량조절이 이루어지게 되므로 방의 크기에 맞도록 개폐판(7)의 개폐량을 조절할 수 있게 되어 과잉 공기를 제어함에 따라 공기유입과잉으로 발생하는 소음을 없앨 수 있고 개폐판과 개방부사이의 간격을 평균적으로 유지한 상태에서 합리적인 공기조화가 이루어지는 효과를 얻게 되며 이로 인하여 외관이 보기 좋으면서 방의 크기에 알맞은 외부 공기공급과 조정이 이루어져 공기 조화가 균형있게 이루어지는 장점을 얻게 되고 기존의 환기구에 본 발명의 조정구(8)를 장치하여 균형잡힌 공기 조화를 달성할 수 있으므로 환기구 자체를 다시 만들지 않아도 되는 이점이 있어서 에너지 비용을 크게 절약할 수 있는 이점을 얻을 수 있게 되고 본 발명의 외부 공기 조정구는 가변형조정구(8) 또는 원판형 조정구(80)중에서 선택하여 방의 크기에 알맞는 량의 외부 공기가 들어오게 주입 통기공의 크기를 조정할 수 있어서 공기량 조정이 편리하게 되는 이점을 얻을 수 있다.The present invention as described above is provided with an adjustment hole (8) (80) for adjusting the size of the injection vent hole in the air supply port (1b) formed on the upper end of the cylindrical body (1a) of the ventilation hole through the external air supply pipe (2) Since the amount of external air injected into the cylindrical body 1a can be supplied in accordance with the size of the room, the supply amount is balanced at the stage of air inflow, and the amount of air supply injected into the room is controlled within the range of the external air entering the ventilation opening. Therefore, the opening and closing amount of the opening and closing plate 7 can be adjusted to fit the size of the room, thereby controlling the excess air, thereby eliminating noise caused by excess air inflow, and maintaining an average distance between the opening and closing plate and the opening. The effect of rational air conditioning is achieved. This makes the external air supply and adjustment suitable for the size of the room with good appearance. It is possible to achieve the advantage that the air conditioning is balanced, and by adjusting the adjustment mechanism 8 of the present invention to the existing air vent, it is possible to achieve a balanced air condition, so that the air vent itself does not need to be rebuilt, thereby greatly reducing energy costs. The external air adjusting device of the present invention can be selected from the variable adjusting device 8 or the disc-shaped adjusting device 80 to adjust the size of the injection vent so that the external air of the amount appropriate to the size of the room comes in. Therefore, the advantage that the air amount adjustment is convenient can be obtained.
