In order to solve these problems, the defects of the product appear due to the difficulty of the non-magnetic material. The electromagnetic induction heating cooker fixed to the main body 2 of the present invention is proposed.

본 발명에서는 알루미늄 등 비자성체의 본체(2)에 자성체의 가열판(1)과 알루미늄 등 비자성체의 본체(2)를 밀착결합시키는 밀착결합부재(5)를 자성체의 가열판(1)에 저항용접하고, 또는, 저항용접으로 용착시킨 후에 다시, 납땜한 자성체의 가열판(1)을 주물로 휘감기는 것과 같이 하여 주조고정하는 것을 요지로 하고 있다.In the present invention, resistance welding is performed on the heating plate 1 of the magnetic body by a close coupling member 5 for tightly coupling the heating plate 1 of the magnetic material to the main body 2 of the nonmagnetic material such as aluminum and the main body 2 of the nonmagnetic material such as aluminum.

[작용][Action]

본 발명의 내용을 도면에 따라 실시예를 상세히 설명하면, 제1도에 도시하는 바와 같이 전자유도가열 조리기(3)에 있어서, 본체(2)를 알루미늄 등의 비자성체로 한 것은 경량화를 목적으로 하고 있고, 또 전열효과를 고려한 것이고, 자성체의 가열판(1)과 철망의 밀착결합부재(5)를 저면에 형성하여 전자유도가열하는 것이다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described in detail with reference to the drawings. In the electromagnetic induction heating cooker 3 as shown in FIG. 1, the main body 2 is made of nonmagnetic material such as aluminum for the purpose of weight reduction. In addition, the heat transfer effect is taken into consideration, and the heating plate 1 of the magnetic body and the close contact member 5 of the wire mesh are formed on the bottom surface to heat the electromagnetic induction.

철망 이외의 밀착결합부재(5)를 사용하는 경우에는, 제2도에 도시하는 바와 같이, 저항용접전극의 아래전극(4)에 밀착결합부재(5)의 위치결정홈(6)을 설치하여 밀착결합부재(5)를 정치시키지만, 위치결정홈(6)의 형상은 벌집모양 뿐만 아니라, 격자상 등 밀착결합부재(5)의 형상에 따라 결정하여도 좋고, 금속빌릿 등 부정형의 형상이 많은 경우에는 형상에 따라 불규칙적으로 간헐적으로 형성하여도 좋은 것은 말할 것도 없다.When using the close coupling member 5 other than the wire mesh, as shown in FIG. 2, the positioning groove 6 of the close coupling member 5 is provided in the lower electrode 4 of the resistance welding electrode. Although the close coupling member 5 is left still, the shape of the positioning groove 6 may be determined not only in the shape of a honeycomb but also in accordance with the shape of the close coupling member 5 such as a lattice, and has a large number of irregular shapes such as metal billets. It goes without saying that the case may be formed irregularly and intermittently depending on the shape.

또, 밀착결합부재(5)를 저항용접전극의 아래전극(4)의 위치결정홈(6)에 정치시켜, 저항용접전극의 위전극(7)과 저항용접전극의 아래전극(4)과의 사이에 상기 저항용접전극의 아래전극(4)에 설치한 위치결정홈(6)에 정치시킨 밀착결합부재(5)를 통하여 자성체의 가열판(1)를 고정하고, 사전에 밀착결합부재(5)와 자성체의 가열판(1)을 저항용접하여 용착시켜, 전자유도가열 조리기(3)에 사용하는 자성체의 가열판(1)으로 하는 것이다.Further, the close coupling member 5 is left in the positioning groove 6 of the lower electrode 4 of the resistance welding electrode, so that the upper electrode 7 of the resistance welding electrode and the lower electrode 4 of the resistance welding electrode are fixed. The heating plate 1 of the magnetic material is fixed through the close coupling member 5 placed in the positioning groove 6 provided in the lower electrode 4 of the resistance welding electrode therebetween, and the close coupling member 5 in advance. And the heating plate 1 of the magnetic body are welded by resistance welding to form the heating plate 1 of the magnetic body used for the electromagnetic induction cooking machine 3.

또, 자성체의 가열판(1)의 철망 등의 밀착결합부재면을 앞면으로 하여 금형(8)에 고정하고, 알루미다이캐스트 등에 의하여 밀착결합부재(5)를 용차시킨 자성체의 가열판(1)을 비자성체를 주물로 휘감기게 하여 전자유도가열 조리기(3)를 주조함으로써, 비자성체의 본체(2)와 밀착결합부재(5)를 용착시킨 자성체의 가열판(1)을 부착강도를 높게 하여 주조할 수가 있고, 방열효과도 좋고, 주조할 때 쇳물흐름 등 주조성도 좋게 한 것이다.The magnetic heating plate 1 of the magnetic body is fixed to the mold 8 with the surface of the close coupling member such as a wire mesh of the heating plate 1 of the magnetic body fixed on the mold 8, and the close coupling member 5 is melted by aluminicasting or the like. By casting the adult body in a casting and casting the electromagnetic induction heating cooker 3, the magnetic heating plate 1 of the non-magnetic body 2 and the close coupling member 5 welded together can be cast with a high adhesive strength. It has good heat dissipation effect and good casting property such as water flow when casting.

또, 자성체의 가열판(1)에 용착시키는 밀착결합부재(5)는 주로 강철, 스테인레스 등의 재료를 임의로 사용하는 철망을 플레이트에 손으로 밀어 사용하지만, 펀칭금속판, 강철구, 스테인레스구, 금속빌릿 등의 재료를 사용하여도 좋은 것은 말할 것도 없고, 밀착결합부재(5)를 자성체의 가열판(1)에 저항용접하는데 지장이 없는 재료이면 좋고, 금속빌릿 등의 경우에는, 부정형의 것이 많기 때문에 위치결정홈(6)은 간헐적으로 설치하는 것도 좋고, 이들 밀착결합부재(5)를 위치결정홈(6)에 정치시켜, 주조할 때 주물로 휘감는 효과를 증대시키는 것이 선택된다.In addition, the close bonding member 5 to be welded to the heating plate 1 of the magnetic material is mainly used by pushing a wire mesh using a material such as steel, stainless steel by hand to the plate, but punched metal plate, steel ball, stainless ball, metal billet, etc. Needless to say, the material may be used as a material that does not interfere with the welding of the close-coupled member 5 to the heating plate 1 of the magnetic material. In the case of metal billets or the like, there are many irregular shapes. The grooves 6 may be provided intermittently, and it is selected to leave these close coupling members 5 in the positioning grooves 6 to increase the effect of being wound into the casting when casting.

또, 제3도에 도시하는 바와 같이, 밀착결합부재(5)를 용착시킨 자성체의 가열판(1)의 말단을 직방향 또는 역테이퍼(10)상의 U자상 단부(9)로 함으로서, 외주(外周)의 강성이 높아졌을 뿐 아니라, 외형치수 정확도도 향상하도록 되어 있다.Moreover, as shown in FIG. 3, the periphery of the heating plate 1 of the magnetic body on which the close coupling member 5 is welded is formed as the U-shaped end portion 9 on the straight or reverse taper 10. In addition to increasing the stiffness, the dimensions accuracy is also improved.

또, 제4도에는 밀착결합부재(5)의 철망을 용착시킨 자성체의 가열판(1)의 말단을 L자형단부(11)로 한 실시예로서, 제5도는 자성체의 가열판(1)의 말단을 L자형으로 하고, 제6도는 자성체의 가열판(1)을 U자형으로 하고, 제7도는 자성체의 가열판(1)을 역테이퍼(10)상의 U자형 단부(9)로 한 것으로서 특히 제7도의 실시예에서는, 주조할 때 역테이퍼(10)상의 U자상 단부(9)가 주물로 휘감기는 것과 같이 되고, 자성체의 가열판(1)의 밀착강도가 향상할 수 있게 되었다.4 is an embodiment in which the end of the heating plate 1 of the magnetic body on which the wire mesh of the close coupling member 5 is welded is formed as the L-shaped end portion 11, and FIG. 5 is the end of the heating plate 1 of the magnetic body. 6 is a U-shaped heating plate 1 of the magnetic substance, and FIG. 7 is a U-shaped end portion 9 on the reverse taper 10 of FIG. In the example, the U-shaped end portion 9 on the reverse taper 10 is wound around the casting during casting, and the adhesion strength of the heating plate 1 of the magnetic body can be improved.

저항용접은 건축에 있어서 대형구조물로부터 초소형의 전자부품에 이르기까지 폭넓게 응용되어 있지만, 점용접, 봉합용접, 돌기용접 등의 겹침용접과 불꽃맞댐용접, 업셋맞댐용접, 충격용접 등의 맞댐용접이 있고, 접합하는 곳에 대전류를 흐르게 하여 점성상태로 하는 것으로 접촉저항에 의한 열에 의하여 금속이 용융된 곳에 압력을 가하여 접합하고, 곧 전류를 끊고 냉각하는 것이다.Resistance welding is widely applied in construction, from large structures to ultra-small electronic components, but there are overlap welding such as spot welding, seam welding, projection welding, butt welding, flame welding, upset welding, impact welding, etc. To make a viscous state by flowing a large current to the junction, joining by applying pressure to the molten metal by the heat of contact resistance, and immediately breaking and cooling the current.

전자유도가열 조리기(3)를 주조할 때, 밀착결합부재(5)를 용착시킨 자성체의 가열판(1)을 저항용접을 사용하여 용착하고 있지만, 저항용접은 금속에 전기를 흐르게 하면 주울열이 발생하고, 이를 열원으로 하여 용접부를 가열함과 동시에 압력을 병용하여 용접하는 것이지만, 용접부를 가압하면서 고주파전류를 직접 모재에 공급하여 행하는 고주파 저항용접을 사용하는 것이 좋은 것은 말할 것도 없고, 밀착결합부재(5)를 저항용접전극의 아래전극(4)의 위치결정홈(6)에 정치시켜, 저항용접전극의 위전극(7)과 저항용접전극의 아래전극(4)과의 사이에, 상기 저항용접전극의 아래전극(4)의 위치결정홈(6)에 정치시킨 밀착결합 부재(5)를 통하여 자성체의 가열판(1)을 고정하고 있기 때문에, 전류를 집중하는데 유용하게 작용할 뿐 아니라, 비교적 작은 전류로 확실한 용접에 의한 용착이 가능하게 되어 이 때문에 열효율도 좋게 되었다.When casting the electromagnetic induction heating cooker 3, the heating plate 1 of the magnetic body on which the close coupling member 5 is welded is welded using resistance welding, but the resistance welding causes Joule heat to be generated when electricity flows through the metal. Although the welding is performed by using the pressure as a heat source and simultaneously welding the weld, it is needless to say that a high frequency resistance welding is performed by supplying a high frequency current directly to the base material while pressurizing the weld. 5) is placed in the positioning groove 6 of the lower electrode 4 of the resistance welding electrode, and the resistance welding is performed between the upper electrode 7 of the resistance welding electrode and the lower electrode 4 of the resistance welding electrode. Since the heating plate 1 of the magnetic material is fixed through the close contact member 5 held in the positioning groove 6 of the lower electrode 4 of the electrode, it not only serves to concentrate the current but also has a relatively small current. By Because of this, the thermal efficiency was also well bonded by welding making it possible ambiguity.

또, 자성체의 가열판(1)에 밀착결합부재(5)를 용착하는데 저항용접을 사용하는 것이 최적임은 말할 것도 없다.It goes without saying that it is optimal to use resistance welding to weld the close coupling member 5 to the heating plate 1 of the magnetic body.

다만, 금속빌릿 등 부정형의 형상의 밀착결합부재(5)를 용착하는 경우, 저항용접전극의 아래전극(4)에 밀착결합부재(5)의 위치결정홈(6)을 설치하여 밀착결합부재(5)를 정치한다 하더라도, 위치결정홈(6)의 형상은 정형적으로 설정하는 것은 어렵고, 형상에 따라 불규치적이고 간헐적으로 형성하는 것은 코스트의 상승과 결부되는 것으로도 되고, 또한 용착이 불완전하게 되는 일이 있기 때문에 밀착결합부재(5)를 저항용접으로 용착시킨 후, 더욱 납땜을 사용하여 모재를 용융하지 않고 결합하는 경(硬)납땜이나, 땜납을 사용하여 모재를 용융하지 않고 결합하는 납땜 등에 의하여 용착하여, 완전한 용착을 하는 밀착결합부재(5)의 용착을 하는 것과 같이, 작업성이나, 밀착결합부재(5)의 종류를 고려하여 자유로이 선택할 수 있는 것은 말할 것도 없다.However, in the case of welding an irregularly shaped close contact member 5 such as a metal billet, the close contact member 5 is provided with a positioning groove 6 of the close contact member 5 in the lower electrode 4 of the resistance welding electrode. Even if 5) is settled, the shape of the positioning groove 6 is difficult to be set in a regular manner, and irregular and intermittent formation depending on the shape may be associated with an increase in cost and incomplete welding. Since the adhesion bonding member 5 is welded by resistance welding, it is possible to use light soldering to bond the base metal without melting, or to solder the base metal without melting using solder. It is needless to say that it is possible to select freely in consideration of workability and the type of the tight coupling member 5, such as welding the tight coupling member 5 which is welded by welding or the like and complete welding.
