Description

本発明は、インダクションヒーターに使用される電磁調理器用容器の製造方法に係り、具体的には非磁性容器の底に磁性パターンを形成する電磁調理器用容器の製造方法に関する。   The present invention relates to a method for manufacturing a container for an electromagnetic cooker used for an induction heater, and specifically relates to a method for manufacturing a container for an electromagnetic cooker in which a magnetic pattern is formed on the bottom of a nonmagnetic container.

一般的にわが国はガス供給施設がよく整えられているため加熱施設の変化を試すことができない。しかしガスによる加熱施設は有害ガスが多量発生していて、火災の危険性もある。またガス加熱施設は一酸化炭素が発生して主婦の健康にも莫大な影響を与えている。現在先進諸国ではインダクションヒーターを広く使用している。インダクションヒーターは電磁誘導により発熱される加熱機として、有害ガスが発生しなく、火災にも比較的安全な長所がある。   In general, we cannot test changes in heating facilities because gas supply facilities are well-equipped. However, gas heating facilities generate a lot of harmful gases and there is a risk of fire. Gas heating facilities generate carbon monoxide and have a huge impact on housewife health. Currently, induction heaters are widely used in developed countries. An induction heater is a heater that generates heat by electromagnetic induction, has no toxic gas, and has a relatively safe fire.

このようなインダクションヒーター(電磁調理器)に使用するための容器は特殊な構造で製造される。即ち、アルミニウムのような非磁性金属を主材料として作られる、飲食物を電磁波で加熱できるようにするためにはこのような電磁波による加熱作用が可能な磁性金属板、望ましいのはステンレス鋼のような磁性金属板を該当調理器の底の外側に付着、設置するのが必要である。   Containers for use in such induction heaters (electromagnetic cookers) are manufactured with a special structure. That is, a magnetic metal plate made of a non-magnetic metal such as aluminum as a main material, and capable of heating food and drink with electromagnetic waves, and preferably with such electromagnetic waves, preferably stainless steel. It is necessary to attach and install a magnetic metal plate on the outside of the bottom of the cooker.

このように物理的性質、特に熱膨張程度がお互い異なる二つの異種の金属板を、相当の温度差の加熱と冷却が繰り返される使用条件の下で、相互間の浮きや変形、脱落などが行われない堅実安定的な、そして外見上美麗な状態で接合させて、目的とする調理器の底部を形成することは、単純な溶接や圧接などの方法では達成することが困難である。   In this way, two dissimilar metal plates with different physical properties, especially thermal expansion levels, are floated, deformed, and dropped off under the conditions of repeated heating and cooling with considerable temperature differences. It is difficult to achieve the desired bottom of the cooker by joining them in a stable, stable and aesthetically pleasing state by a simple method such as welding or pressure welding.

このような問題を解決するために使用された従来の一つの方法としては、ステンレス鋼素材の磁性金属板の片側面に花の模様の突出物等を形成して、この磁性金属板を上記の突出物等が非磁性金属板に向かうように配置した状態で、上記の磁性金属板及び非磁性金属板をお互いプレス圧接させると、上記の磁性金属板上の突出物等が非磁性金属板の方へ食い込みながら変形されて両金属板間の結合になるような方法が使用されたことがある。   One conventional method used to solve such problems is to form a flower pattern protrusion on one side of a magnetic metal plate made of stainless steel, and use this magnetic metal plate as described above. When the magnetic metal plate and the nonmagnetic metal plate are press-contacted with each other in a state where the protrusions are arranged so as to face the nonmagnetic metal plate, the protrusions on the magnetic metal plate are not attached to the nonmagnetic metal plate. In some cases, a method has been used in which the metal plate is deformed while being bitten in the direction and becomes a bond between the two metal plates.

このような方法は、韓国公開特許第2004−0004034号公報または韓国登録特許第1034759号公報に開示されている。
ところがこのような先行技術等においても未だに問題点が存在する。即ち、上記の韓国特許公開第2004−0004034号公報に開示された技術は、磁性金属であるステンレスが非磁性金属であるアルミニウムを食い込みながら相互結合される過程で、アルミニウムが変形されてクラックが発生されたり、ステンレスの突出部がアルミニウムと正常に結合されなく外側へ反れてしまいアルミニウムとの結合力が弱くなる問題点がある。
一方、韓国登録特許第1034759号公報で開示された技術は、アルミニウムに溝を形成して、ステンレス突出部を該当溝と結合した後アルミニウムを圧着させることにより該当溝部を埋めるようにした構造である。この韓国登録特許第1034759号公報で開示された方法は、溝部を埋めるようにアルミニウムを圧着する過程でアルミニウムの表面が変形されてしまい、屈曲が発生したり、アルミニウムが割れる問題が発生する。
Such a method is disclosed in Korean Patent No. 2004-040434 or Korean Patent No. 1034759.
However, there are still problems in such prior art. In other words, the technique disclosed in the above-mentioned Korean Patent Publication No. 2004-040434 is a process in which aluminum is deformed and cracks are generated in a process in which stainless steel, which is a magnetic metal, is interconnected while biting aluminum, which is a nonmagnetic metal. There is a problem that the protruding portion of the stainless steel is not normally bonded to the aluminum and is bent outward and the bonding force with the aluminum is weakened.
On the other hand, the technology disclosed in Korean Patent No. 1034759 is a structure in which a groove is formed in aluminum, and the corresponding groove is filled by crimping aluminum after bonding the stainless steel protrusion to the groove. . In the method disclosed in the Korean Patent No. 1034759, the surface of aluminum is deformed in the process of crimping aluminum so as to fill the groove, which causes a problem of bending or breaking of the aluminum.

韓国公開特許第2004−0004034号公報Korean Published Patent No. 2004-040434 韓国登録特許第1034759号公報Korean Registered Patent No. 1034759

図1乃至図7を参照すると、本発明の望ましい実施例による電磁調理器用容器の(10)の製造方法は、非磁性金属で作られた本体(20)に磁性金属で作られた加熱パターン部材(30)が結合された電磁調理器用容器(10)の製造方法に関するものである。   Referring to FIGS. 1 to 7, a method of manufacturing a container for an electromagnetic cooker according to a preferred embodiment of the present invention includes a heating pattern member made of a magnetic metal on a body made of a nonmagnetic metal. The present invention relates to a method for manufacturing a container (10) for an electromagnetic cooker combined with (30).

上記の電磁調理器用容器(10)の製造方法は、加熱パターン部材の加工工程(S1)と、結合溝部の形成工程(S2)と、結合工程(S3)と、研磨工程(S4)を含む。   The method for manufacturing the container for electromagnetic cooker (10) includes a heating pattern member processing step (S1), a coupling groove portion forming step (S2), a coupling step (S3), and a polishing step (S4).

上記の底(32)は板状の部材である。上記の底(32)は上記の加熱パターン部材(30)の胴体に当たる。上記の突出部(34)は上記の底(32)から後述する本体(20)に向けて突出された部位である。上記の突出部(34)はいわゆる円筒型に形成されて、その突出部(34)の内側は穴(36)が形成される。上記の突出部(34)の深さは2mm未満である場合には上記の本体(20)と結合力が弱い問題点がある。
一方、上記の突出部(34)の長さが5mmを超過する場合には上記の本体(20)と結合した時その本体(20)に挿入される量が大きくなり、上記本体(20)の変形または破損が発生されるという問題点がある。
Referring to FIG. 4, in the heating pattern member processing step (S <b> 1), the heating pattern member (30) is processed with a portion for coupling with the main body (20). The heating pattern member (30) includes a bottom (32), a protrusion (34), and a hole (36).
The bottom (32) is a plate-like member. The bottom (32) hits the body of the heating pattern member (30). Said protrusion part (34) is a site | part protruded toward the main body (20) mentioned later from said bottom (32). The protrusion (34) is formed in a so-called cylindrical shape, and a hole (36) is formed inside the protrusion (34). When the depth of the protrusion (34) is less than 2 mm, there is a problem that the coupling force with the main body (20) is weak.
On the other hand, when the length of the protrusion (34) exceeds 5 mm, the amount inserted into the main body (20) when combined with the main body (20) increases, There is a problem that deformation or damage occurs.

一方、上記の加熱パターン部材の加工工程(S1)において、上記の加熱パターン部材(30)に加圧部(38)を形成する。上記の加圧部(38)は上記の加熱パターン部材(30)の外周枠部に配置される。
上記の加圧部(38)は上記の底(32)に対して45°上向角度に曲がることにより形成される。上記の加圧部(38)は語述する結合工程で上記の加熱パターン部材(30)を本体(20)に加圧するための加圧支持部になる。また上記の加圧部(38)は上記の結合工程(S3)で広がることで本体(20)と上記の加熱パターン部材(30)が堅固に結合されるようにする役割を遂行する。
上記の加熱パターン部材(30)はいわゆるステンレス鋼板のような磁性体により製造される。上記の加熱パターン部材(30)はプレス加工のような公知された方法により製造することができる。
On the other hand, in the heating pattern member processing step (S1), the pressurizing portion (38) is formed on the heating pattern member (30). Said pressurization part (38) is arrange | positioned at the outer periphery frame part of said heating pattern member (30).
The pressurizing part (38) is formed by bending an angle of 45 ° upward with respect to the bottom (32). The pressurizing part (38) serves as a pressurizing support part for pressurizing the heating pattern member (30) to the main body (20) in the coupling step described. Further, the pressurizing part (38) performs a role of firmly joining the main body (20) and the heating pattern member (30) by spreading in the joining step (S3).
The heating pattern member (30) is made of a magnetic material such as a so-called stainless steel plate. The heating pattern member (30) can be manufactured by a known method such as press working.

図3を参照すると、上記の結合溝部の形成工程(S2)においては、本体(20)に上記の突出部(34)と結合される溝部(22)を形成する。上記の本体(20)は内部に飲食を受容できる凹んだ形状の器である。本発明は上記の本体(20)の底面の構造を製造する方法に関するものである。上記の本体(20)は溝部(22)と挿入部(27)と平坦部(28)を含む。   Referring to FIG. 3, in the above-described coupling groove forming step (S2), a groove (22) to be coupled to the protrusion (34) is formed in the main body (20). Said main body (20) is a bowl-shaped container which can receive food and drink inside. The present invention relates to a method of manufacturing the structure of the bottom surface of the main body (20). The main body (20) includes a groove portion (22), an insertion portion (27), and a flat portion (28).

上記の溝部(22)は上記の本体(20)の表面から内側に向けて凹んだ形状で形成される。上記の溝部(22)は第1溝部(24)と第2溝部(25)を含む。上記の第1溝部(24)は上記の溝部(22)の縦方向から上部に配置される。上記の第2溝部(25)は上記の第1溝部(24)の下側に配置される。
上記の第1溝部(24)は上記の第1溝部(24)より狭い幅を持つ。上記の第1溝部(24)と上記の第2溝部(25)の幅の差により上記の第1溝部(24)と上記の第2溝部(25)の境界には図3で図示されたように段差(26)が形成される。上記の溝部(22)の大きさは上記の突出部(34)が上記の段差(26)を崩壊させてその突出部(34)の下側の空間が埋められるように設定するのが望ましい。上記の段差(26)は図3で図示されたとおり、第1溝部(24)と第2溝部(25)の間に階段の形態に角をなすように形成されることができる。一方、上記の段差(26)は図3で図示されているのとは異なり、円満な曲線の形態に形成されることができる。
Said groove part (22) is formed in the shape dented inward from the surface of said main body (20). The groove portion (22) includes a first groove portion (24) and a second groove portion (25). Said 1st groove part (24) is arrange | positioned from the vertical direction of said groove part (22) to the upper part. Said 2nd groove part (25) is arrange | positioned under said 1st groove part (24).
The first groove (24) has a narrower width than the first groove (24). The boundary between the first groove portion (24) and the second groove portion (25) is illustrated in FIG. 3 due to the difference in width between the first groove portion (24) and the second groove portion (25). A step (26) is formed on the surface. The size of the groove (22) is preferably set so that the protrusion (34) collapses the step (26) and fills the space below the protrusion (34). As shown in FIG. 3, the step (26) may be formed between the first groove portion (24) and the second groove portion (25) so as to form a corner in the form of a staircase. On the other hand, the step 26 is different from that shown in FIG. 3 and may be formed in a full curve.

上記の挿入部(27)は上記の結合溝部の形成工程(S2)で形成される。上記の挿入部(27)は上記の加熱パターン部材(30)に形成された突出部(34)の内側に受容された部位である。即ち、上記の挿入部(27)は上記の穴(36)の内側に受容される。   The insertion portion (27) is formed in the coupling groove portion forming step (S2). Said insertion part (27) is a site | part received inside the protrusion part (34) formed in said heating pattern member (30). That is, the insertion part (27) is received inside the hole (36).

上記の平坦部(28)は上記の加熱パターン部材(30)の底(32)により被される部位である。上記の平坦部(28)と上記の挿入部(27)の間に上記の溝部(22)が配置される。上記の挿入部(27)の高さは上記の平坦部(28)より高く形成される。   The flat portion (28) is a portion covered by the bottom (32) of the heating pattern member (30). The groove portion (22) is disposed between the flat portion (28) and the insertion portion (27). The height of the insertion part (27) is formed higher than the flat part (28).

上記の本体(20)が板材や鋳物で製造される場合には、上記の挿入部(27)と上記の平坦部(28)の高さの差異(h)は、上記の加熱パターン部材(30)の厚さより0.1mm乃至0.3mm大きいのが望ましい。上記の高さの差異(h)が上記の加熱パターン部材(30)の厚さより0.1mm未満で大きく形成された場合には、後述する研磨工程(S4)で上記の加熱パターン部材(30)が研磨されることによりその加熱パターン部材(30)の厚さが薄くなり、耐久性が悪化される問題点がある。
一方、上記の高さの差異(h)が上記の加熱パターン部材(30)の厚さより0.3mmを超過するぐらい大きく形成された場合には、後述する研磨工程(S4)で上記の挿入部(27)の上部を研磨して上記の加熱パターン部材(30)の上面と同一の高さに研磨する工程の時間が延びることで工程の効率性が悪化する問題点がある。
上記の本体(20)が鋳物で製造される場合に、上記の挿入部(27)と上記の平坦部(28)は上記の本体(20)を鋳造した後に底面を切削して形成する。上記の本体(20)を板材で製造する場合に、上記の挿入部(27)と上記の平坦部(28)は鍛造金型を利用して形成する。
When the main body (20) is manufactured of a plate material or a casting, the difference (h) in height between the insertion portion (27) and the flat portion (28) is the heating pattern member (30). It is desirable that the thickness is 0.1 mm to 0.3 mm larger than the thickness. When the height difference (h) is formed to be larger than the thickness of the heating pattern member (30) by less than 0.1 mm, the heating pattern member (30) is polished in a polishing step (S4) described later. As a result of the polishing, the thickness of the heating pattern member (30) becomes thin, and the durability deteriorates.
On the other hand, when the height difference (h) is formed to be larger than the thickness of the heating pattern member (30) by more than 0.3 mm, the insertion portion is removed in a polishing step (S4) described later. There is a problem that the efficiency of the process deteriorates because the time of the process of polishing the upper part of (27) and polishing it to the same height as the upper surface of the heating pattern member (30) is extended.
When the main body (20) is manufactured by casting, the insertion portion (27) and the flat portion (28) are formed by cutting the bottom surface after casting the main body (20). When the main body (20) is manufactured from a plate material, the insertion portion (27) and the flat portion (28) are formed using a forging die.

一方、上記の結合溝部の形成工程(S2)において、上記の本体(20)がダイキャスティング方式により製造される場合には、上記の挿入部(27)の高さは上記の平坦部(28)より高く形成されるが、その高さの差異(h)は上記の加熱パターン部材(30)の厚さと同一のものが望ましい。
ダイキャスティング方式により上記の本体(20)が製造される場合には、上記の挿入部(27)の上段部が上記の研磨工程(S4)で研磨される量が殆どないほど微々であるためである。上記の本体(20)をダイキャスティング方式により製造する場合に上記の挿入部(27)と上記の平坦部(28)はダイキャスティング金型により形成される。上記の本体(20)をダイキャスティング方式で加工する場合には、上記の本体(20)と上記の加熱パターン部材(30)の結合工程後の境界部位の平坦度が板材や鋳造方式の場合より優秀である。
On the other hand, when the main body (20) is manufactured by a die casting method in the coupling groove forming step (S2), the height of the insertion portion (27) is the flat portion (28). The height difference (h) is preferably the same as the thickness of the heating pattern member (30).
When the main body (20) is manufactured by the die casting method, the upper portion of the insertion portion (27) is so small that there is almost no amount to be polished in the polishing step (S4). is there. When the main body (20) is manufactured by a die casting method, the insertion portion (27) and the flat portion (28) are formed by a die casting mold. In the case where the main body (20) is processed by a die casting method, the flatness of the boundary portion after the joining process of the main body (20) and the heating pattern member (30) is higher than that in the case of a plate material or a casting method. Excellent.

上記の結合溝部の形成工程(S2)において、上記の溝部(22)の深さは上記の突出部(34)の長さと同じになるように形成する。   In the step of forming the coupling groove (S2), the depth of the groove (22) is formed to be the same as the length of the protrusion (34).

図5及び図6を参照すると、上記の結合工程(S3)においては、上記の本体(20)と上記の加熱パターン部材(30)を相互結合する。さらに具体的に上記の結合溝部の形成工程(S2)後に上記の突出部(34)の下段が上記の段差に引っかかるように上記の加熱パターン部材(30)を配置する。
即ち、上記の突出部(34)が上記の第1溝部(24)に挿入されるように配置する。その状態で上記の加熱パターン部材(30)を上記の本体(20)に接近する方向に加圧する。これにより上記の突出部(34)が上記の段差(26)を崩壊させながら上記の本体(20)へ食い込んで結合する。
崩壊された上記の段差(26)は上記の突出部(34)に形成された穴の外側下部の空間を埋める。即ち、上記の段差が崩壊されて第2溝部(25)及び上記の第2溝部(25)の空間を埋める事で上記の突出部(34)が上記の本体(20)と堅固に結合される。
Referring to FIGS. 5 and 6, in the coupling step (S3), the main body (20) and the heating pattern member (30) are coupled to each other. More specifically, the heating pattern member (30) is arranged so that the lower step of the protrusion (34) is caught by the step after the formation step (S2) of the coupling groove.
That is, it arrange | positions so that said protrusion part (34) may be inserted in said 1st groove part (24). In this state, the heating pattern member (30) is pressurized in a direction approaching the main body (20). Thereby, said protrusion part (34) bites and couple | bonds with said main body (20), collapsing said level | step difference (26).
The collapsed step (26) fills the space outside the hole formed in the protrusion (34). That is, when the step is collapsed and the space between the second groove portion (25) and the second groove portion (25) is filled, the protrusion (34) is firmly coupled to the main body (20). .

上記の研磨工程(S4)においては、上記の結合工程(S3)後に上記の本体(20)の上面を研磨する。上記の研磨工程(S4)で上記の本体(20)と上記の加熱パターン部材(30)の上面が同一な高さになるようにする。上記の研磨工程(S4)が完了された容器の断面構造は図7で図示されたとおりである。   In the polishing step (S4), the upper surface of the main body (20) is polished after the bonding step (S3). In the polishing step (S4), the upper surface of the main body (20) and the heating pattern member (30) are set to the same height. The cross-sectional structure of the container after the above polishing step (S4) is as shown in FIG.

このように本発明による電磁調理器用容器の製造方法は磁性体である加熱パターン部材と非磁性体である本体を結合する過程で上記の本体に圧力を直接的にかけない。従って、従来の方法に比べて結合工程で本体にクラックが発生するなどの問題が発生しない。また、本発明による電磁調理器用容器の製造方法は上記の加熱パターン部材の突出部が第1溝部と第2溝部の2段で形成された境界部位の段差を崩壊させながら、その溝部の空間を埋めるので本体の変形が発生しない。従って、結合工程の結合効率が向上されて本体内部に欠陥発生が少なくなるので耐久性が向上される効果がある。   Thus, the manufacturing method of the container for electromagnetic cookers by this invention does not apply a pressure directly to said main body in the process which couple | bonds the heating pattern member which is a magnetic body, and the main body which is a nonmagnetic body. Therefore, there is no problem that cracks occur in the main body in the joining process as compared with the conventional method. In addition, in the method for manufacturing a container for an electromagnetic cooker according to the present invention, while the protruding portion of the heating pattern member collapses the step at the boundary portion formed by the two steps of the first groove portion and the second groove portion, the space of the groove portion is reduced. Since it is buried, the main body is not deformed. Accordingly, the coupling efficiency of the coupling process is improved, and the occurrence of defects in the main body is reduced, so that the durability is improved.

上記の電磁調理器用容器にサラダ油を入れてインダクションヒーターで220℃まで5回加熱した後、容器の底の中央部位が底の直径に対してどのぐらい変化しているかを測定した。従来の方法により製造された容器は底の変化率が0.8〜1%であったが、本発明により製造された容器は0.5%以下の底変化率を示したことで、従来の方法に比べて耐久性が向上されたものと期待される。また熱効率の側面では、従来の方法により製造された容器は誘導電力が1.7〜1.8kWから始まり時間の経過により1.55〜1.6kWの値を示したが、本発明により製造された容器は誘導電力が1.8〜1.9kWから始まり時間の経過により1.7〜1.8kWの値を維持することと把握された。従って、本発明により製造された容器の熱効率が高いというのが分かる。   After the salad oil was put into the above-mentioned container for an electromagnetic cooker and heated to 220 ° C. five times with an induction heater, how much the central part of the bottom of the container changed with respect to the diameter of the bottom was measured. Although the container manufactured by the conventional method has a bottom change rate of 0.8 to 1%, the container manufactured according to the present invention has a bottom change rate of 0.5% or less. It is expected that durability is improved compared to the method. Further, in terms of thermal efficiency, the container manufactured by the conventional method started from 1.7 to 1.8 kW and showed a value of 1.55 to 1.6 kW over time. It was understood that the container had an induced power of 1.8 to 1.9 kW and maintained a value of 1.7 to 1.8 kW over time. Therefore, it can be seen that the container manufactured according to the present invention has high thermal efficiency.

このように本発明により電磁調理器用容器の製造方法は非磁性体である本体に2段の溝を形成することにより磁性体である加熱パターン部材の突出部が上記の溝に形成された段差を崩壊されながらその崩壊された部位が上記の突出部と溝の間の空間を埋める事で本体と加熱パターン部材が堅固に結合されて本体に亀裂が発生しないので、耐久性が優秀で熱効率が向上された電磁調理器用容器を提供する効果がある。   As described above, according to the present invention, the method for manufacturing the container for an electromagnetic cooker forms the two-step groove in the main body which is a non-magnetic material, so that the protruding portion of the heating pattern member which is a magnetic material has the step formed in the groove. While collapsed, the collapsed part fills the space between the protruding part and the groove, so the main body and the heating pattern member are firmly connected and no cracks occur in the main body, so it has excellent durability and improved thermal efficiency There is an effect of providing a container for an electromagnetic cooker.

以上、本発明を望ましい実施例を挙げて詳細に説明したが、本発明は上記の実施例に限らなく、本発明の技術的事象内で当分野において通常の知識を持つ者により様々な変形が可能であることは明白である。   The present invention has been described in detail with reference to the preferred embodiments.
