이들 도면에서 볼 수 있는 바와 같이, 본 발명에 따른 면상발열체(1)는, 단결정유리와 강화유리 중 선택된 어느 하나의 면상유리판(10)을 구비하며, 면상유리판(10)의 저면에 Ag-Pd-Pt/Ag-Pd로 이루어진 전극재로 일정한 패턴의 열선(20)을 인쇄하는 방식으로 형성하되, 열선(20) 일단에 단자부(30)를 형성시키고 있다. 여기서 단자부(30)는 3상으로 형성된다.As can be seen in these figures, the planar heating element 1 according to the present invention includes any planar glass plate 10 selected from single crystal glass and tempered glass, and has Ag-Pd on the bottom surface of the planar glass plate 10.

도 3은 본 발명에 따른 제조공정을 도시한 블록도이다.3 is a block diagram showing a manufacturing process according to the present invention.

상기 도면에서 볼 수 있는 바와 같이, 본 발명에 따르면, 단결정유리와 강화유리 중 선택된 어느 하나의 면상유리판(10)을 준비하는 단계(S10)와, 면상유리판(10)의 저면에 Ag-Pd-Pt/Ag-Pd로 이루어진 전극재를 일단에 단자부(30)가 형성되도록 일정한 패턴으로 열선(20)을 인쇄한 후 800℃?860℃로 소성하는 단계(S20)를 거친다. 이후 상기 단자부(30)의 상면에 Ag 피막층(40)을 형성한 후 상기 Ag 피막층(40)을 800℃?860℃로 소성하는 단계(S30)에 이어서 Ag 피막층(40)을 제외한 열선(20)을 포함하며 면상유리판(10) 저면 전체에 세라믹피막층(50)을 형성한 후 350℃?400℃로 소성하는 단계(S40)를 거친다. 그리고 단자부(30)의 Ag 피막층(40)에 전원인가선(60)을 납땜 용착하는 단계(S50)에 의해 본 본명에 따른 면상발열체(1)가 제조된다.As can be seen in the figure, according to the present invention, the step (S10) of preparing any one of the planar glass plate selected from single crystal glass and tempered glass, Ag-Pd- on the bottom surface of the planar glass plate 10 After the heating wire 20 is printed in a predetermined pattern so that the terminal portion 30 is formed at one end of the electrode material made of Pt / Ag-Pd, it is subjected to a step S20 of firing at 800 ° C. to 860 ° C. After the Ag film layer 40 is formed on the upper surface of the terminal portion 30, the Ag film layer 40 is fired at 800 ° C to 860 ° C (S30), followed by the heating wire 20 except for the Ag film layer 40. After forming the ceramic film layer 50 on the entire bottom surface of the planar glass plate 10 and then firing at 350 ℃ ~ 400 ℃ (S40). The planar heating element 1 according to the present invention is manufactured by the step (S50) of soldering and welding the power supply wire 60 to the Ag film layer 40 of the terminal portion 30.

이상과 같은 본 발명에서, Ag-Pd-Pt/Ag-Pd로 이루어진 전극재로 열선(20)을 형성한 것은 고온에서도 열선(20)이 견딜 수 있도록 하기 위함이다. 따라서 면상유리판(10)에 400℃?700℃까지 온도를 상승시켜 음식을 신속하게 조리할 수 있다. 특히, 본 발명은 면상유리판(10) 저면에 열선(20)을 형성하고, 열 충격 및 영팽창계수가 같은 세라믹피막층(50)을 열선(20)에서 단자부(30)를 제외한 면상유리판(10)의 저면 전체에 피막함으로써 열선(20)의 숏트를 방지하고 열효율을 상승시키며, 열이 면상유리판(10)의 아래쪽으로 방출되지 않게 되고, 따라서 면상유리판(10) 표면에 직접 열이 발생하므로 음식을 신속하게 조리할 수 있다. 예컨대 종래에는 400℃까지 상승되는데 3000W정도의 전기가 소모되는데 비하여 본원 발명은 1200W 정도 밖에 소모되지 않아 전기 소모량도 약 60％ 절약된다.In the present invention as described above, the heating wire 20 is formed of an electrode material made of Ag-Pd-Pt / Ag-Pd is to allow the heating wire 20 to withstand even at high temperatures. Therefore, by raising the temperature to 400 ° C ~ 700 ° C on the planar glass plate 10 it is possible to quickly cook food. Particularly, in the present invention, the planar glass plate 10 is formed on the bottom surface of the planar glass plate 10, and the ceramic coating layer 50 having the same thermal shock and Young's expansion coefficient has the terminal portion 30 removed from the terminal part 30. The coating on the entire bottom surface prevents shorting of the heating wire 20 and increases the thermal efficiency, and heat is not released to the bottom of the planar glass plate 10, and thus heat is generated directly on the surface of the planar glass plate 10. You can cook quickly. For example, while the conventional electric power is raised to 400 ° C., about 3000W of electricity is consumed, the present invention consumes only about 1200W, thus saving about 60% of electricity consumption.

본 발명은 종래와 달리 열선(20)을 형성함에 있어서 Ag-Pd-Pt/Ag-Pd로 이루어진 전극재를 사용하고 열선(20) 상면에서 단자부(30)를 제외한 면상유리판(10)의 저면 전체면에 세라믹피막층(50)을 형성하는 것으로서 노이즈 발생이 없게 된다.The present invention, unlike the prior art in forming the heating wire 20 using the electrode material consisting of Ag-Pd-Pt / Ag-Pd and the entire bottom surface of the planar glass plate 10 except for the terminal portion 30 on the upper surface of the heating wire 20 The ceramic coating layer 50 is formed on the surface so that no noise is generated.
