본 발명은 온풍기에 관한 것으로, 특히 온풍기 본체의 후방에 송풍 블로워를장착하여 온풍기 본체 내부에 장착된 오일버너에서 발생되는 고온의 온풍을 적정온도로 낮추어 배출시키고, 온풍기 본체의 전방에는 내부에 흡입 블로워가 내장된 외부배출기가 선택적으로 결합되어 낮추어진 온풍을 외부로 신속하게 배출시킴으로써 그 용량이 크게 되어 비교적 큰 규모에 적용이 가능하여 넓은 범위의 온풍이 가능 하 도록 구성한 간접 온풍기에 관한 것이다.The present invention relates to a hot air blower, and in particular, by installing a blow blower at the rear of the hot air blower main body, the hot air generated by the oil burner mounted inside the hot air blower body is lowered and discharged to a proper temperature, and a blow blower inside the hot air blower main body is discharged. It is related to an indirect warmer configured to allow a wide range of warm air to be applied to a relatively large scale by increasing the capacity of the built-in external discharger is selectively coupled to quickly discharge the lowered warm air to the outside.

일반적으로 열풍기는 본체 내에 히터나 코일로 된 열선을 마련하고, 이에 전 기를 연결하여 흡입된 기체를 높은 온도로 상승시킨 다음, 송풍팬을 이용하여 외부로 배출시키는 전열방식을 갖거나, 연소실 내에서 연료를 연소시켜 발생한 높은 온도의 고열을 외부로 토출시키는 연소 가열방식으로 기기이다.In general, a hot air fan has a heating wire made of a heater or a coil in the main body, and has an electric heating method in which a heated gas is heated to a high temperature by connecting an electric wire, and then discharged to the outside using a blower fan, or in a combustion chamber. It is a combustion heating method that discharges high temperature high heat generated by burning fuel to the outside.

이러한 열풍기는 토출구를 통해 직접 토출되는 열풍의 범위가 열풍기와 근접되는 위치는 온도가 높고, 멀리 떨어진 위치는 온도가 상대적으로 낮아 실내 전체의 온도 조절이 용이하지 못하게 되었으며, 이를 해소하기 위해서는 열풍기를 계속적으로 가동시키거나 여러대의 열풍기를 사용하여야 하는 문제점이 발생되었다.The hot air is hot in the location where the range of hot air discharged directly through the discharge port is close to the hot air, and the distance is far from the remote air, which makes it difficult to control the temperature of the entire room. There has been a problem of operating with or using multiple hot air fans.

이러한 문제점을 해결하기 위해서 본 출원인은 특허 등록번호 10-055771호(발명의 명칭: 열풍기)를 개발하였다. 이는 열풍기에서 발생되는 고열과 외부공기를 혼합하여 적정 온도로 낮추어진 열풍을 외부로 배출시키는 구조로 이루어진 것이다.In order to solve this problem, the applicant has developed Patent Registration No. 10-055771 (name of the invention: hot air blower). This is composed of a structure that discharges the hot air lowered to an appropriate temperature by mixing the high heat generated from the hot air and the outside air to the outside.

이와 같은 종래 열풍기에 대하여 첨부된 도면을 참조로 설명하면, 도 1은 종래 온풍기의 내부구조를 도시한 단면도이고, 도 2a,2b는 종래 온풍기의 동작상태를 도시한 단면도이다.Referring to the accompanying drawings for such a conventional hot air fan, Figure 1 is a cross-sectional view showing the internal structure of a conventional hot air fan, Figure 2a, 2b is a cross-sectional view showing the operating state of a conventional hot air fan.

도 1 및 도 2에 도시된 바와 같이, 종래 열풍기는 외관을 이루는 열풍기 본체(100)와; 열풍기 본체(100) 내부에 설치되어 연소공간을 마련하는 연소실(200)과; 연소실(200)을 감싸는 차열판(300)과; 열풍기 본체(100) 일측에 설치되어 연소실(200) 내부로 고열의 열을 발생시키는 버너(400)와; 버너(400)에서 발생되는 고열과 외부 공기를 혼합하여 적정 온도로 낮아진 열풍을 배출시키는 온도조절수단으로 이루어진다.As shown in Figure 1 and 2, the conventional hot air blower and the hot air blower body 100 forming an appearance; A combustion chamber 200 installed in the hot air blower main body 100 to provide a combustion space; A heat shield plate 300 surrounding the combustion chamber 200; A burner 400 installed at one side of the hot air blower main body 100 to generate heat of high heat into the combustion chamber 200; It consists of a temperature control means for discharging the hot air lowered to an appropriate temperature by mixing the high heat generated from the burner 400 and the outside air.

이와 같이 구성되는 종래의 열풍기는, 주로 공장 대형 식당, 비닐하우스, 화원, 축사 등의 난방에 적용하여 사용하게 되는 것이다. The conventional heat blower configured as described above is mainly used for heating in factories, large restaurants, vinyl houses, flower gardens, barns, and the like.

이는, 내측 비닐하우스(510)와 외측 비닐하우스(520) 사이에 난방공간(530)이 형성되도록 지면에 설치된 비닐하우스(500)의 난방공간(530)과 열풍기 본체(100)의 배출관(220)을 별도의 연결관(600)을 통해 연결하게 된다.This, the heating space 530 of the vinyl house 500 installed on the ground so that the heating space 530 is formed between the inner vinyl house 510 and the outer vinyl house 520 and the discharge pipe 220 of the hot air blower body 100 To be connected through a separate connector (600).

이러한 상태에서 차열판(300)의 연도(310)에 설치된 개폐부재(320)를 회전시켜 연도(330)가 열리도록 한 다음, 열풍기에 전원을 공급하여 버너(400)를 가열시키면, 연소실(200)에 고열이 발생되고, 고열에 의해 연소실(200)의 개구부에 설치된 열판(220)이 가열된다.In this state, by rotating the opening and closing member 320 installed in the flue 310 of the heat shield plate 300 to open the flue 330, and then supplying power to the hot air fan to heat the burner 400, the combustion chamber 200 ), A high heat is generated, and the hot plate 220 provided in the opening of the combustion chamber 200 is heated by the high heat.

이와 같이 발생되는 고열은 열풍기의 전원공급에 따라 작동되는 송풍기(700)에 의해 열풍기 본체(100)의 공기유입공(110)을 통하여 유입되는 외부공기와 혼합하는 과정을 통해 그 온도가 낮아진 열풍으로 변환되어 배출관(230)을 통하여 외부로 배출된다.The high heat generated as described above is a hot air whose temperature is lowered by mixing with the outside air introduced through the air inlet hole 110 of the hot air blower body 100 by the blower 700 operated according to the power supply of the hot air blower. The converted and discharged to the outside through the discharge pipe 230.

이렇게 배출관(220)을 통하여 배출되는 열풍은 연결관(600)을 통해 비닐하우스(500)의 난방공간(530)의 내부로 유입되어 비닐 하우스(500)의 실내가 적정 온도로 난방되는 것이다. The hot air discharged through the discharge pipe 220 is introduced into the heating space 530 of the vinyl house 500 through the connection pipe 600 so that the interior of the vinyl house 500 is heated to an appropriate temperature.

그러나, 이와 같은 종래의 열풍기는 그 용량이 작아 비교적 큰 비닐하우스 등에 난방을 하기에 적당하지 못하게 되어 여러대를 설치해야 하는 문제점과, 자체 용량을 늘리기 위해서는 제품의 전체가 커지게 되는 문제점이 발생 되었다.However, such a conventional hot air blower is not suitable for heating a relatively large vinyl house due to its small capacity, which causes the problem of having to install several units and a problem that the entire product becomes large in order to increase its capacity. .

본 발명은 이와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 본 발명은 온풍기 본체의 후방에 송풍 블로워를 장착하여 온풍기 본체 내부의 오일버너에서 발생되는 고온의 온풍을 적정온도로 낮추어 배출시키고, 온풍기 본체의 전방에는 내부에 흡입 블로워가 내장된 외부배출기가 결합되어 낮추어진 온풍을 흡입하여 외부로 배출시킴으로써 그 용량이 크게 되어 비교적 큰 규모에 적용이 가능하여 넓은 범위의 온풍이 가능하도록 구성한 간접 온풍기를 제공하는 데 그 목적이 있다.The present invention has been made to solve such a conventional problem, the present invention is equipped with a blow blower in the rear of the hot air blower body to lower the high temperature hot air generated by the oil burner inside the hot air blower body to an appropriate temperature and discharge, The front of the main body is equipped with an external blower with a built-in suction blower inside, so that the lowered warm air is sucked out and discharged to the outside, so that its capacity is increased, so it can be applied to a relatively large scale. The purpose is to provide.
