1 : 케이스 3 : 수용실1: case 3: storage room

4 : 액체대류실 5 : 열원 장입요함실4: liquid convection chamber 5: heat source charging chamber

종래의 보온도시락은 원통형으로 된 진공보온방식 또는 스티로포울등 단열재로 중후하게 형성한 것등이 있으나 이들은 모두 부피가 너무커서 휴대하기가 불편하고 파손될 유려가 있어서 사용수명이 짧은 결점이 있었다.Conventional thermal insulation has been formed with a thick vacuum insulation or styrofoam insulators, etc., but these are all too large to be convenient to carry and breakage, there was a short service life shortcomings.

본 고안은 이러한 결점을 제거하기 위하여 납짝한 사각형의 케이스에 ㄷ자형의 도시락 수용실을 형성하여 그 둘레에 밀폐된 액체대류실을 형성하고 이 액체대류실속에는 한쪽만 트인 열원 장입요함실을 요설한 것으로 열원으로 액체대류실내의 액체에 열을 가하여 대류케 하므로서 도시락 수용실내를 보온케한 것인데 첨부 도면에 의거 상세히 설명하면 다음과 같다. 납짝한 사각형의 케이스(1)에 ㄷ자형의 도시락(2) 수용실 (3)을 형성하여 그 둘레에 밀폐된 액체대류실(4)을 형성하고 이 액체대류실(4) 속에는 한쪽만 트인 열원 장입요함실 (5)을 요설하여서된 것이다.In order to eliminate this drawback, the present invention forms a U-shaped lunch box in a flat rectangular case to form a sealed liquid convection chamber. The liquid convection chamber is provided with a heat source charging chamber. By heat convection by applying heat to the liquid in the liquid convection chamber as a heat source is to keep the interior of the lunch box storage room described in detail according to the accompanying drawings. A c-shaped lunch box (2) receiving chamber (3) is formed in a flat rectangular case (1) to form a sealed liquid convection chamber (4) therein, and a heat source having only one open side in the liquid convection chamber (4). It was made by a summary of the charging chamber (5).

도면중 미설명부호 6은 스라이드전, 7은 액체주입구전, 8은 솜, 8'는 기름주입구전, 9는 연료통, 10은 석면, 11은 코일, 12는 화구를 표시한 것임.In the drawings, reference numeral 6 denotes a slide before, 7 denotes a liquid inlet, 8 denotes a cotton, 8 'denotes an oil inlet, 9 denotes a fuel container, 10 denotes asbestos, 11 denotes a coil, and 12 denotes a crater.

이와같이 구성된 본 고안의 작용효과를 표시한면 다음과 같다.The following shows the effects of the present invention configured as described above.

납짝하게 사각형으로 형성된 케이스(1)에 ㄷ자형의 도시락(2) 수용실(3)을 형성하여 스라이드전(6) 개폐로 도시락(2)을 넣다꺼냈다하고 수용실(3) 둘레에 형성된 액체대류실(4) 속에는 열원 장입요함실(5)을 요설하였기 때문에 이에 열원을 장착하면 액체의 냉각열을 보충하므로 수용실(3)이 보온되어서 도시락(2)이 항상 균일하게 보온되는 효과가 있다. 그리고 열원의 일례로서 널리 알려지고 있는 통상의 주머니 회로를 이용할 경우에는 솜(8)을 넣은 연료통(9) 돌구에 섬유질 석면(10)을 코일(11)로 감싸서 넣은 오목한 화구(12)를 장착하였기 때문에 기름주입구전(8')을 열고 알콜, 또는 라이터용 기름등 휘발성이 좋은 연료를 주입하고 화구(12) 코일(11)측을 점화하면 그 속의 석면(10)을 통과하는 증발 연료가 순식간에 착화하여 불꽃없이 완전 연소를 지속한다. 따라서 냄새도 나지 않으므로 위생적이다.A c-shaped lunch box (2) receiving chamber (3) was formed in the case (1) formed in a flat rectangular shape, and the lunch box (2) was put out by opening and closing the slide (6) and the liquid convection formed around the receiving chamber (3). Since the heat source charging chamber 5 is provided in the chamber 4, when the heat source is attached thereto, the cooling heat of the liquid is replenished, so that the storage chamber 3 is kept warm so that the lunch box 2 is always uniformly insulated. In the case of using a common bag circuit, which is widely known as an example of a heat source, a concave crater 12 in which a fibrous asbestos 10 is enclosed with a coil 11 is mounted on a fuel tank 9 protrusion in which a cotton 8 is inserted. Therefore, when the fuel injection port 8 'is opened and alcohol or a volatile fuel such as a lighter oil is injected and the ignition burner 12 is ignited, the evaporative fuel passing through the asbestos 10 therein is instantly absorbed. Ignition, complete combustion without flame. It is therefore hygienic because it does not smell.
