Abstract

PURPOSE: An electric hot blower is provided to improve heating efficiency while having a reduced size by heating and blowing intake air using a heating unit. CONSTITUTION: An electric hot blower comprises a blowing chamber(2), a blowing fan, a discharge tube(10), a heating unit(15), and an outdoor air intake pipe(20). The outdoor air, which is discharged and sucked by the blowing fan is heated and blown by the heating unit in the discharge tube. An intake hole(21) and a supply hole(22) are formed outside the discharge tube. The intake hole sucks in the outdoor air. The supply hole supplies the outdoor air to the blowing chamber. The outdoor air intake pipe installed with a dual structure blows and heats the outdoor air in a preheated state by being heat-exchanged with the discharge tube.

이때, 상기 외기흡입관(20)의 공급공(22)에는 외기의 이물질을 여과 공급하도록 필터부(30)가 설치 구성된다. At this time, the filter unit 30 is installed in the supply hole 22 of the outside air suction pipe 20 so as to filter and supply foreign substances from the outside air.

또한, 상기 토출관 내부의 가열부(15)는 중앙에 외기를 나선 안내하면서 가열하는 스크류 타입 히터(16)와 외측에 나선형 코일 히터(17)가 복수 설치 구성된다.In addition, the heating unit 15 inside the discharge tube is provided with a plurality of screw type heaters 16 for heating while helically guiding outside air in the center and a plurality of spiral coil heaters 17 on the outside.

그리고 상기 토출관(10)은 단일 또는 도면에서와 같이 2개의 토출관을 병렬 구성할 수 있음은 물론이다.And the discharge pipe 10 can be configured as a single or two discharge pipes in parallel as shown in the drawing.

또한, 상기 외기흡입관(20)은 토출관(10)의 외부를 전체적으로 감싸는 이중 구조나 토출관(10)의 상,하부만을 감싸는 이중 구조 등 토출관과의 열교환을 이루를 수 있는 다양한 이중 구조로 형성할 수 있음은 물론이다.In addition, the outside air suction pipe 20 has a variety of dual structures that can achieve heat exchange with the discharge pipe, such as a double structure that covers the entire outside of the discharge pipe 10 or a double structure that covers only the upper and lower portions of the discharge pipe 10. Of course, it can form.

또한, 상기 스크류 타입 히터(16)는 외기를 나선형으로 안내하기 위해 스크류 형태로 형성하되, 내부 길이방향으로 전기 히터(미도시)를 삽입 구성하고 있다.In addition, the screw-type heater 16 is formed in the form of a screw to guide the outside air in a spiral, it is configured to insert an electric heater (not shown) in the inner longitudinal direction.

다음은 상기와 같이 구성되는 본 발명의 작동 및 작용에 대해 살펴보기로 한다.Hereinafter, the operation and operation of the present invention will be described.

본 발명은 실내 및 하우스 등의 내부 공간에 설치되어 송풍실(2)의 송풍팬(5)에 의해 흡입 토출되는 외기를 가열하여 열풍으로 토출하므로 내부 공간의 온도 상승 조절하도록 사용되는 것이다.The present invention is to be used to adjust the temperature rise of the internal space because it is installed in the interior space, such as indoors and houses, and discharges the outside air sucked and discharged by the blowing fan 5 of the blowing chamber 2 by hot air.

특히, 송풍팬(5)에 의해 흡입되는 외기는 토출관 외부에 이중 구조로 구성된 외기흡입관(20)의 흡입공(21)을 통해 흡입되어 외기를 가열 송풍하는 토출관(10) 외측면을 따라 이동하면서 토출관과의 열교환에 의해 1차 예열하게 된다.In particular, the outside air sucked by the blower fan 5 is sucked through the suction hole 21 of the outside air suction pipe 20 having a double structure outside the discharge pipe, along the outer surface of the discharge pipe 10 for heating and blowing the outside air. While moving, primary heat is preheated by heat exchange with the discharge tube.

이와 같이 1차 예열된 외기는 송풍실(2)과 연결되는 공급공(22)에서 필터부(30)에 의해 이물질을 여과한 상태로 송풍팬(3)을 경유하여 토출관(10)으로 토출되면서 2차 가열되어 송풍하게 되는 것이다.In this way, the first preheated outdoor air is discharged to the discharge pipe 10 via the blower fan 3 while the foreign matter is filtered by the filter unit 30 in the supply hole 22 connected to the blower chamber 2. Will be heated secondarily and blown.

즉, 상기 송풍팬(5)에 흡입되는 외기를 토출관에 의해 1차 예열한 상태로 토출관 내부의 가열부(15)에 2차 가열하여 송풍하기 때문에 열풍의 가열 효과가 우수하게 제공되는 것이다.That is, since the outdoor air sucked into the blower fan 5 is secondarily heated and blown by the heating unit 15 inside the discharge tube in the state of being preheated by the discharge tube first, the heating effect of the hot air is excellently provided. .

더우기, 상기 토출관(10) 내부의 가열부(15)는 중앙에 스크류 타입 히터(16)와 외측에 나선형 코일 히터(17)를 복수 설치하고 있기 때문에 외기가 스크류 타입 히터(16)에 의해 나선 안내되어 히터와의 열접촉 시간, 면적을 극대화하면서 내외측 히터에 의해 가열되므로 열풍의 가열 효과를 더더욱 극대화하게 되는 것이다.Furthermore, since the heater 15 inside the discharge tube 10 is provided with a plurality of screw type heaters 16 at the center and a spiral coil heater 17 at the outside, the outside air is spiraled by the screw type heaters 16. The guide is heated by the inner and outer heaters while maximizing the thermal contact time and area with the heater, thereby maximizing the heating effect of the hot air.

따라서, 본 발명은 컴팩트한 구조로 외기를 흡입, 토출하는 외기 흡입관, 토출관에서 1,2차 가열 송풍함은 물론 토출관 내부에서 내외측 히터에 의해 효과적으로 가열하므로 에너지를 절감 효과 및 열풍의 가열 효과를 우수하게 제공하게 되는 것이다.Therefore, the present invention has a compact structure, which effectively blows the first and second heating blowers in the outside air suction pipe and the discharge pipe that sucks and discharges the outside air, as well as effectively heats the internal and external heaters inside the discharge pipe, thereby saving energy and heating the hot air. It will provide an excellent effect.
