본 발명은 본체의 바닥부에 비해 입구가 좁거나 두께가 얇은 조리기구에도 열전도판을 압착고정형성하여 유도가열식으로 구성해줄 수 있도록 한 조리기구의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a cooking utensil to be formed in the induction heating type by pressing the heat conduction plate fixed to the cooking utensils narrower or thinner than the bottom of the main body.

후라이팬이나 냄비 등과 같은 각종 조리기구의 바닥부에 열전도판을 압착고정하여 유도가열식으로 구성한 조리기구는 이미 오래전부터 출시되고 있고 그 열전도판에 대하여는 이미 특허 제555626호를 제공한 바 있다.Cooking utensils constructed by induction heating by pressing and fixing a heat conduction plate on the bottom of various cooking utensils such as a frying pan or a pot have already been released for a long time and have already provided the patent for the heat conduction plate.

이러한 유도가열식 조리기구들은 본체와 열전도판을 별도로 제작하여 완성된 본체의 바닥부 저면에 열전도판을 압착고정형성해 주도록 한 것으로서, 다양한 종류의 조리기구들 중 작업조건을 만족하는 일부특정 조리기구에만 적용해줄 수 있을 뿐 바닥부에 비해 입구가 좁거나 또는 본체의 두께가 얇은 조리기구에는 적용해줄 수가 없게 된다.These induction heating cookers are manufactured by separately forming the main body and the heat conduction plate so as to compress and form the heat conduction plate on the bottom of the bottom of the finished body, and apply only to some specific cookware satisfying the working conditions among various kinds of cookware. It can only be applied to cookware that has a narrow entrance or thin body compared to the bottom.

즉 조리기구 본체와 열전도판의 결합은 프레스기에 의해 이루어지는 것으로서, 작업시 완성된 형태의 본체를 뒤집은 상태로 형틀에 결합하여 그 바닥부가 형틀에 밀착되게 한 다음 바닥부상에 삽입관이 저부를 향하도록 열전도판을 얹고 프레스기로 가압하여 상기 열전도판이 본체의 바닥부에 압착고정형성되도록 하므로서 본체의 입구가 바닥부 직경에 비해 작을 경우 형틀과의 결합이 이루어질 수 없게 되므로 주전자 등과 같이 입구가 좁은 조리기구는 유도가열식으로 구성해줄 수 없는 단점을 지니게 된다.In other words, the combination of the main body of the cookware and the heat conduction plate is made by a press machine, and when the work is completed, the main body of the completed form is turned upside down to be coupled to the mold so that the bottom part is in close contact with the mold, and then the insertion tube faces the bottom part. Since the heat conduction plate is pressed onto the bottom of the main body by pressing the heat conduction plate and fixedly formed at the bottom of the main body, when the inlet of the main body is smaller than the diameter of the bottom part, the combination with the mold cannot be made. Induction heating has a disadvantage that can not be configured.

또한 열전도판은 특허 제555626호와 같이 기능상 요구되는 두께는 약 0.4~0.5㎜이고 여기에 고정용 삽입관이 갖는 높이인 약 0.6~1.1㎜가 더해져 전체두께는 약 1.0~1.6㎜로서 열전도판이 본체의 바닥부에 정상적으로 압착고정되게 하기 위하여는 본체의 바닥부 두께는 최소한 2.0㎜ 이상은 유지해주어야 하므로 두께가 얇은 조리기구 역시 유도가열식으로 구성해줄 수 없는 단점을 지니게 되며, 그렇다 하여 단순히 열전도판을 압착고정해주기 위하여 본체의 두께를 두껍게 형성해주고자 할 경우에도 그 적용범위는 그 입구가 바닥부 직경보다 큰 조리기구로 한정되고 또 재료비의 상승을 가져오게 됨은 물론 무게가 가중되어 사용상 불편함이 따르게 되는 등의 단점들을 지니게 되는 것이다.In addition, the thermal conductive plate is required to have a functional thickness of about 0.4 to 0.5 mm, as in Patent No. 555626, and a height of about 0.6 to 1.1 mm, which is the height of the fixed insertion tube, is added to the total thickness of about 1.0 to 1.6 mm. In order to ensure that the bottom of the main body is normally pressed at least, the thickness of the bottom of the main body should be maintained at least 2.0 mm. Therefore, even a thin cookware has a disadvantage in that it cannot be constructed by induction heating. Even if the thickness of the main body is to be formed in order to fix it, the scope of application is limited to the cooking utensils whose openings are larger than the diameter of the bottom part, which leads to an increase in the cost of materials as well as the inconvenience of using them due to the weight. Will have the disadvantages.

본 발명의 목적은 상술한 종래기술이 갖는 문제점들을 감안하여 바닥부에 비해 입구의 직경이 작거나 또는 두께가 얇은 조리기구에도 일반 프레스기를 이용하여 열전도판을 간단히 압착고정형성해줄 수가 있는 유도가열식 조리기구의 제조방법을 제공하고자 한다.An object of the present invention is an induction heating type cooking that can easily press-fix the heat conduction plate using a general press machine even in a cookware having a small diameter or a small thickness of the inlet compared to the bottom in view of the problems of the prior art described above. It is intended to provide a method of manufacturing a device.

상기한 본 발명의 목적은 충분한 두께를 갖는 알루미늄원판을 드로잉가공형성하여 전절단하고 그 바닥부를 제외한 나머지부분을 얇게 가공형성한 상태에서 형틀상에 결합하고 그 바닥부상에 열전도판을 삽입관이 저부를 향하도록 얹어서 프레스가압하여 열전도판이 바닥부에 압착고정되게 한 다음 얇은 측면부를 직선 또는 곡선으로 기울게 가공형성하여 완전한 형상을 갖도록 한 유도가열식 조리기구의 제조방법에 의해 달성된다.The above object of the present invention is to draw and cut an aluminum disc having a sufficient thickness to pre-cut it, and to combine the mold in a state in which the remaining portion except the bottom is formed in a thin form and the heat conduction plate is inserted into the bottom of the insert tube. It is achieved by a method of manufacturing an induction heating type cookware which is pressed to press and then press-pressed to heat-fix the heat conduction plate to the bottom part, and then form a thin side part in a straight line or a curve to be inclined to have a perfect shape.

본 발명은 적정두께의 알루미늄 원판을 드로잉가공형성하여 전절단으로 1차성형물(2)을 얻도록하는 단계와, 상기 1차성형물(2)의 측면부(2a)를 얇게 성형하여 2차 성형물(4)를 얻도록 하는 단계와, 2차성형물(4)의 바닥부(4b) 저변에 미리 제작된 열전도판(6)을 압착고정형성하여 3차성형물(8)을 얻도록 하는 단계 및 두께가 얇은 측면부(10a)를 직선이나 또는 곡선으로 기울게 하여 완전한 형상의 4차성형물(10)을 얻도록 하는 단계로 이루어진다.According to the present invention, a step of forming an aluminum disc having an appropriate thickness to obtain a primary molded part (2) at full cutting, and forming a thin side surface portion (2a) of the primary molded part (2) to form a secondary molded part (4) ) To obtain a third molded article (8) by pressing and forming a thermally conductive plate (6) prepared in advance on the bottom of the bottom portion (4b) of the second molded article (4) The side portion 10a is inclined in a straight line or in a curved line so as to obtain a quaternary molded product 10 having a perfect shape.

본 발명에 이용되는 알루미늄 원판은 전체적으로 열전도판(6)이 안정감 있게 압착고정될 수 있는 충분한 두께를 갖는 것으로서, 드로잉가공으로 그 측면부를 스트레이트형으로 형성하고 또 전절단해주는 것으로 1차성형물(2)을 얻게 된다.The aluminum disc used in the present invention has a thickness sufficient to allow the heat conduction plate 6 to be crimped and securely as a whole. The primary molded part 2 is formed by forming a side part in a straight shape by the drawing process. You get

상기 1차성형물(2)은 측면부(2a)와 바닥부(2b)가 같은 두께로서 이중 그 측면부(2a)를 아이어닝(ironing)이나 스피닝가공 등으로 얇게 형성해주므로서 2차성형물(4)을 얻게 되는데 이때 그 입구가(4b)가 갖는 직경은 바닥부(4b) 직경과 거의 같거나 큰 직경을 유지할 수가 있게 된다.The primary molded part 2 has the same thickness as that of the side part 2a and the bottom part 2b. In this case, the diameter of the inlet 4b can be maintained to be about the same or larger than the diameter of the bottom 4b.

또한 2차성형물(4)은 바닥부(4b)는 두껍고 측면부(4a)는 얇으며 그 입구(4c)는 바닥부(4b)와 같은 직경으로 넓은 것으로서, 뒤집은 상태에서 넓은 입구(4c)를 통하여 프레스기의 형틀 상에 결합하여 그 바닥부(4b)가 형틀과 접촉되게 하고 상기 바닥부(4b) 위에 미리 제작된 열전도판(6)을 삽입관이 아래로 향하도록 얹고 프레스기로 가압성형하여 상기 열전도판(6)이 본체의 바닥부(4b)에 압착고정되게 해주는 것으로 3차성형물(8)을 얻게 된다.In addition, the secondary molding 4 has a thick bottom portion 4b, a thin side portion 4a, and a wide inlet 4c having the same diameter as the bottom portion 4b. The bottom portion 4b is coupled to the mold of the press, and the bottom portion 4b is brought into contact with the mold. The heat conduction plate 6, which is prefabricated, is placed on the bottom portion 4b with the insertion tube facing downward and press-molded with a press to form the heat conduction. The plate 6 is pressed onto the bottom 4b of the main body to obtain a tertiary molding 8.

다만 열전도판(6)은 2차성형물(4)에만 압착고정해줄 수 있는 것이 아니라 이 역시 입구(4b)가 넓은 1차성형물(2)에도 압착고정해주더라도 무방하다.However, the heat conduction plate 6 may not only be fixed to the secondary molded part 4 but also may be fixed to the primary molded part 2 having a wide inlet 4b.

상기 3차성형물(8)은 두께가 얇은 측면부(8a)를 벤딩 내지는 조임 등으로 직선 내지는 곡선으로 기울게 가공형성하여 원하는 형상으로 형성해 주므로서 본체로서의 완전한 형상인 4차성형물(10)을 얻게 된다.The tertiary molded product 8 is formed by forming a desired shape by processing the thin side portion 8a in a straight line or a curve by bending or tightening to form a desired shape, thereby obtaining a quaternary molded product 10 that is a perfect shape as a main body.

따라서 4차성형물(10)을 얻기 위한 측면부(8a)의 벤딩 내지는 조임시에는 그 측면부(10a)형상과 입구(10c)의 직경을 원하는 다양한 형상과 크기로 형성해줄 수가 있게 되므로 거의 모든 조리기구에 열전도판(6)을 압착고정해줄 수가 있게 된다.Therefore, when bending or tightening the side portion 8a to obtain the fourth molded product 10, the shape of the side portion 10a and the diameter of the inlet 10c can be formed in various shapes and sizes desired. The heat conduction plate 6 can be crimped and fixed.

그리고 4차가공물(10)은 바닥 마스킹과 아노다이징 및 불소 내지는 내열도장 등으로 마감처리하고 또 얻고자 하는 조리기구, 예를 들어 주전자의 경우 주둥이와 손잡이 연결편 등을 연결형성해 주므로서 도 5에서와 같이 조리기구(12)로서의 완성된 형태를 얻을 수 있게 되는 것이다.And the fourth processed article 10 is finished with a bottom masking and anodizing and fluorine or heat-resistant coating, and also to form a cooking utensil, for example, a spout and a handle connecting piece, such as a kettle, as shown in Figure 5 The completed form as the cooking utensil 12 can be obtained.

이와같이 본 발명은 본체의 측면부 형상이 복잡하거나 또는 입구(10c)가 좁은 조리기구에도 열전도판(6)을 간단히 압착고정해줄 수가 있어 보다 다양한 종류의 유도가열식 조리기구를 제공할 수가 있게 되고 또 열전도판(6)이 압착고정되는 바닥부(10b)의 두께는 두껍게 하면서 그 측면부(10a)의 두께는 얇게 형성해줄 수가 있어 제작시 재료비를 절감할 수 없게 됨은 물론 경량화로 취급이 용이한 등의 효과를 얻을 수가 있는 것이다.As described above, the present invention can easily fix and fix the heat conduction plate 6 even in a cookware having a complicated side shape of the main body or a narrow inlet 10c, thereby providing more various kinds of induction heating cookware. The thickness of the bottom portion 10b to which 6 is crimped and fixed can be made thick, and the thickness of the side portion 10a can be made thin, so that the material cost can not be reduced during manufacturing, and the weight can be easily handled. You can get it.
