종래 고주파유도가열기의 가열용기(1)는 제1도에 도시되는 바와같이, 열전도성이양호한 알루미늄재로 만들어지며 전체적으로 용기형상을 가지는 통부(2)와, 자성체인 스테인레스재이며 용기형상으로 형성되어 통부(2)의 외주면에 전체적으로접합되는 자성체부(3)와, 통부(2)의 내주면에 코팅도어 통부(2)의 부식을 방지하는 코팅부(4)로 구성된다.As shown in FIG. 1, the heating container 1 of the conventional high frequency induction heater is made of aluminum having good thermal conductivity and has a tube portion 2 having a container shape as a whole, and is formed of a stainless steel material having a container shape and having a container shape. It is composed of a magnetic body portion 3 which is joined to the outer peripheral surface of the tube portion 2 as a whole, and a coating portion 4 to prevent corrosion of the coating door tube portion 2 on the inner circumferential surface of the tube portion 2.
이와같이 구성되는 종래 고주파유도가열기의 가열용기 제조방법은 제2도와 제3도에 도시되는 바와같이, 상기 통부(2)의 소재인 알루미늄판(2a)과 자성체부(3)의 소재인 스테인레스판(3a)을 중첩한 상태에서 압연롤러(5)의 사이로 이송시켜 알루미늄판(2a)과 스테인레스판(3a)을 접합시키는 접합공정과; 접합공정을 통하여 접합된 소재의 소정의 크기를 가지는 원형판으로 절단하는 절단공정과; 절단공정을 통하여 원형판으로 절단된 소재의 알루미늄판(2a) 표면에 부식이 방지되도록 코팅부(4)를 형성하는 코팅공정과; 코팅공정을 통하여 알루미늄판(2a)의 표면이 코팅된 원형판을 용기형상의 가열용기(1)는 형성하는 프레스성형하는 성형공정과; 성형공정을 통하여 성형된 용기에 수위표시를 각인하는 눈금각인공정으로 이루어진다.The method for manufacturing a heating container of a conventional high frequency induction heater configured as described above is a stainless plate which is a material of the aluminum plate 2a, which is the material of the tube part 2, and the magnetic body part 3, as shown in FIG. A joining step of joining the aluminum plate 2a and the stainless plate 3a by transferring them between the rolling rollers 5 in the state of overlapping (3a); A cutting step of cutting into a circular plate having a predetermined size of the joined material through the joining step; A coating step of forming a coating part 4 to prevent corrosion on the surface of the aluminum plate 2a of the material cut into a circular plate through a cutting step; A molding step of forming a circular plate coated with the surface of the aluminum plate 2a by the coating process to form a container-shaped heating container 1; It consists of a graduation stamping process of stamping the water level display on the molded container through the molding process.
그러나, 상기에서와 같이 구성 및 제조되는 종래 고주파유도가열기의 가열용기 (1)는 알루미늄재인 통부(2)의 외주연에 전체적으로 스테인레스재인 자성체부(3)가 저합되므로, 원가가 상승되는 문제점이 있었다.However, in the heating vessel 1 of the conventional high frequency induction heater constructed and manufactured as described above, since the magnetic body portion 3 made of stainless steel is totally bonded to the outer circumference of the tube portion 2 made of aluminum, the cost increases. there was.
또한, 알루미늄판(2a)과 스테인레스판(3a)을 압연롤러(5)로 압연하여 접합시키크로 접합되는 두 금 속의 두께가 일정하지 않기 때문에, 프레스 성형공정시 소재의 두께에 따라서 그 두께에 적합한 여러벌이 성형금형을 별도로 제작하여야 하므로 금형제작비용이 과다하게 소요되는 문제점과, 이로 인하여 가열용기의 치수가 불균일한 문제점이 있었다.In addition, since the thickness of the two metals joined together by rolling the aluminum plate 2a and the stainless plate 3a with the rolling roller 5 is not constant, it is suitable for the thickness depending on the thickness of the material during the press molding process. Since multiple molds have to be manufactured separately, there is a problem in that the mold manufacturing cost is excessively consumed, and thus, the dimensions of the heating container are uneven.
본 발명의 목적은 상기에서와 같은 종래의 결점을 해소하기 위해, 알루미늄판을 성형하여 통부를 형성하고, 그 통부의 하부에 즉, 자력선이 미치는 부위에만 스테인레스로 성형된 자성체부를 브레이징(brazing)으로 접합시켜, 원가절감 및 치수가 균일한 가열용기를 생산할 수 있는 고주파유도가열기의 가열용기 및 그 제조방법을 제공하는데 있다.An object of the present invention is to form a tube part by forming an aluminum plate in order to solve the conventional drawbacks as described above, by brazing the magnetic body portion formed of stainless steel only in the lower portion of the tube portion, that is, the magnetic force line The present invention provides a heating container for a high frequency induction heater and a method of manufacturing the same, which can be bonded to produce a heating container with reduced cost and uniform dimensions.
이하 첨부된 도면에 따라서 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention according to the accompanying drawings in detail.
본 발명 고주파유도가열기의 가열용기(100)는 제4도와 제5도에 도시된 바와같이, 열전도성이 양호한 알루미늄재로 만들어지며, 전체적으로 용기형상으로 가지는 통부(10)의 하부오주면에 자력선이 미치는 부위까지만 브레이징(brazing)으로 접합도는 자성체부(20)와; 통부(10)의 내주면에 코팅되어 통부(19)의 부식을 방지하는 코팅부 (30)로 구성됨을 그 기술적 구성상의 기본적인 특징으로 한다.The heating vessel 100 of the high frequency induction heater of the present invention is made of aluminum material having good thermal conductivity, as shown in FIGS. 4 and 5, and has a magnetic force line on the lower circumferential surface of the tube portion 10 having a container shape as a whole. Magnetic body portion 20 and the bonding degree by brazing only to the affected area; The coating is formed on the inner circumferential surface of the tube portion 10 to prevent corrosion of the tube portion 19 is a basic feature of the technical configuration.
여기에서 상기 자성체부(20)가 접합되는 통부(10)의 하부외주면에는 자성체부 (20)의 두께 만큼 파여지는 접합홈부(11)를 형성하여, 자성체부(20)의 접합시 요철부가 형성되지 않도록 한다.Herein, the lower outer circumferential surface of the tubular portion 10 to which the magnetic body portion 20 is joined is formed with a joining groove portion 11 which is dug as much as the thickness of the magnetic body portion 20, so that the uneven portion is not formed when the magnetic body portion 20 is joined. Do not
이러한 본 발명의 가열용기(100)는 제6도에 도시되는 바와같이 고주파유도가열기에 설치되는 것으로, 그 작동관계를 설명하면 다음과 같다.The heating vessel 100 of the present invention is installed in the high frequency induction heater as shown in Figure 6, the operation relationship will be described as follows.
즉, 제6도는 본 발명 가열용기(100)의 사용상태를 나타낸 것으로, 도면부호 40은 페라이트(ferrite), 50은 코일베이스, 60은 워크코일(work coil), 70은 용기 베이스를 각각 나타내며, 위크코일(60)에 고주파 전류가 흐르면 위크코일(60)에서 자력선이 발생하고, 이 자력선은 상기 가열용기의 자성체부(20)에 전달도어 자성체부(20)에 와전류(eddy current)가 흐르게 된다. 따라서, 자성체부(20)에서 줄(joul e)열이 발생되고, 이때 발생되는 줄열은 통부(10)에 전달되어 고주파유도가열이 되는 것이다.That is, Figure 6 shows the state of use of the heating vessel 100 of the present invention, 40 is a ferrite (ferrite), 50 is a coil base, 60 is a work coil (work coil), 70 is a container base, respectively When a high frequency current flows in the weak coil 60, a magnetic force line is generated in the weak coil 60, and the magnetic force line is transmitted to the magnetic body part 20 of the heating vessel, and an eddy current flows in the magnetic body part 20. . Therefore, a joule heat is generated in the magnetic body part 20, and the joule heat generated at this time is transmitted to the tube part 10 to be a high frequency induction heating.
이와 같이 작동되는 고주파유도가열기에 있어서, 가열용기는 반드시 유도가열이 가능한 재질을 사용하여야 하며, 또한 열전달이 양호한 재질을 사용하여야 한다.In the high frequency induction heater operated as described above, the heating vessel must be made of a material capable of induction heating and a material having good heat transfer.
즉, 통부(10)는 열전도성이 양호한 알루미늄재를 사용하여, 자성체부(20)는 자성체인 스테인레스재를 사용함이 바람직하다.That is, it is preferable that the cylinder part 10 uses the aluminum material with favorable thermal conductivity, and the magnetic body part 20 uses the stainless material which is a magnetic body.
그러나, 실제로 위크코일(60)에서 발생하는 자력선은 거리의 제곱에 반비례하므로 어느 거리상 떨어진 자성체부(20)에는 자력선이 미치지 못하므로 그 부위는 가열되지 않기 때문에, 워크코닐(60)의 주변에만 즉, 자력선이 미치는 부위에만 자성체부 (20)를 설치하면 유도가열에는 아무런 지장을 초래하지 않는다. 따라서 본 발명에서는 통부(10)의 하부에만 즉, 자력선이 미치는 부위까지만 자성체부(20)를 접합시키므로, 종래와 같이 통부의 전체적인 스테인레스재인 자성체부를 접합시키지 않기 때문에 원가를 절감하면서도 종래와 동일한 유도가열성능을 얻을 수 있는 장점이 있다.However, in practice, the magnetic force lines generated in the weak coil 60 are inversely proportional to the square of the distance, so the magnetic force lines do not reach the magnetic body parts 20 which are separated from each other. , If the magnetic body portion 20 is installed only at the site of the magnetic force line does not cause any disruption to the induction heating. Therefore, in the present invention, since the magnetic body portion 20 is bonded only to the lower portion of the tube portion 10, i.e., only to the portion of the magnetic force line, the magnetic body portion, which is the entire stainless steel portion of the tube, is not joined, thus reducing the cost and reducing the cost. There is an advantage to performance.
한편, 상기에서와 같이 구성되는 본 발명 고주파유도가열기의 가열용기 제조방법을 첨부된 도면에 따라서 상세히 설명하면 다음과 같다.On the other hand, when described in detail according to the accompanying drawings the heating container manufacturing method of the high frequency induction heater of the present invention configured as described above are as follows.
본 발명 고주파유도가열의 가열용기 제조방법은 제7도에 도시되는 바와같이, 상기 통부(10)의 소재인 알루미늄판(10a)을 원판으로 절단하는 알루미늄판 절단공정과 ; 절단된 알루미늄 원판의 표면에 부식이 방지되도록 코팅부(30)를 형성하는 코팅공장과 ; 코팅된 알루미늄 원판을 용기형상의 통부(10)로 프레스성형하는 통부성형공정과 ; 성형된 통부(10)에 수위표시를 각인하는 눈금각인공정과 ; 자성체부(20)의 소재인 스테인레스판(20a)을 원판으로 절단하는 스테인레스판 절단공정과 ; 절단된 스테인레스 원판을 용기형상의 자성체부(20)로 프레스성형하는 자성체부성형공정과 ; 상기 자성체부성형공정을 통하여 성형된 자성체부(20)를 상기 통부의 하부외주면에 자력선이 미치는 부위까지만 브레이징(brazing)으로 접합하는 접합공정을 거치면서 만들어지는 것을 그 기술적 구성상의 특징으로 한다.According to the present invention, a method for manufacturing a heating container for high frequency induction heating includes: cutting an aluminum plate (10a), which is a raw material of the tube portion (10), into a disc; A coating factory forming a coating part 30 to prevent corrosion on the surface of the cut aluminum disc; A tube forming step of press-molding the coated aluminum disc into a container-shaped tube portion 10; A graduation stamping step of marking the water level display on the molded tube part 10; A stainless plate cutting step of cutting the stainless plate 20a, which is a material of the magnetic body part 20, into a disc; Magnetic body shaping | molding process of press-molding the cut | disconnected stainless disc into the container-shaped magnetic body part 20; The technical feature of the technical configuration is that the magnetic body portion 20 formed through the magnetic body shaping process is made through a bonding process for brazing only the portion of the magnetic force line applied to the lower outer peripheral surface of the tube portion by brazing.
이와같이 구성되는 본 발명의 제조방법은 종래와 같이 통부 및 자성체부의 금속판들을 2중접합 시키지 않기 때문에, 통부(10) 및 자성체부(20)의 두께가 매우 균일하므로 여러벌의 금형제작이 삭제되어 원가가 절감되며, 또한 치수가 균일한 가열 용기를 생산할 수 있는 장점이 있다.Since the manufacturing method of the present invention configured as described above does not double-bond the metal parts of the tube part and the magnetic body part as in the prior art, the thickness of the tube part 10 and the magnetic body part 20 is very uniform, so that a plurality of molds are eliminated and the cost is eliminated. Has the advantage of being able to produce a heating vessel with uniform dimensions.
이상에서 살펴본 바와같이 본 발명은 알루미늄판을 성형하고 통부를 형성한후, 그 통부의 하부에 즉, 자력선이 미치는 부위에만 스테인레스로 성형된 자성체부를 브렝징(brazing)으로 접합시켜서 고주파유도가열기으 가열용기를 제조하므로, 가열용기의 원가절감은 물론 치수가 균일한 가열용기를 생산할 수 있는 매우 유용한 발명이다.As described above, the present invention forms an aluminum plate and forms a tube portion, and then joins a magnetic body formed of stainless steel to the lower portion of the tube portion, that is, a portion of the magnetic force line by brazing, so that a high frequency induction heater is used. Since the heating vessel is manufactured, it is a very useful invention that can produce a heating vessel with uniform dimensions as well as cost reduction of the heating vessel.
