た。Conventionally, in this type of electric cooker, the heating plate and sheathed heater were often joined by placing the sheathed heater on top of the heating plate and placing the brazing material between them to heat the brazing material. After the hot plate and sheathed heater were joined, the hot plate was surface-treated with fluororesin or the like.

図面を参照して説明する。Electric cooking appliances made in this way undergo surface treatment after the hot plate and sheathed heater are joined, so if a coating or baking defect occurs during surface treatment, not only will the yield of the product itself deteriorate. However, sheathed heaters were also treated as defective, making them extremely uneconomical and resulting in high costs. Furthermore, the above drawbacks can be overcome by joining a sheathed heater to a hot plate whose surface has been treated with fluorocarbon resin using the brazing method, but under the conditions of the brazing method, heating at 500 to 620°C is not possible for more than 10 minutes. Because it is necessary, the fluororesin decomposes and deteriorates, causing
Several surface treatments were damaged and it was not easy to manufacture. The present invention eliminates the drawbacks of the above-mentioned conventional method of manufacturing an electric cooking appliance, and embodiments of the present invention will be described below with reference to the accompanying drawings.
１５まず、電気調理器用の熱板１、例えばアルミニウム
製の熱板の表面にフッ素樹脂２で表面処理を施す。15 First, the surface of a hot plate 1 for an electric cooker, for example, a hot plate made of aluminum, is subjected to surface treatment with fluororesin 2.

よい。This surface treatment is extremely easy because it involves coating a flat plate with fluororesin and then baking it. A sheathed heater 4 is placed on the back surface of the hot plate 1 which has been subjected to this surface treatment, with a brazing material 3 such as aluminum brazing material 20 interposed therebetween, and the hot plate 1 is placed in an electric furnace.
For example, it is placed in a tunnel-shaped electric furnace. sheathed heater 4
25, an insulating filler 7 such as magnesium oxide is filled between a metal pipe 5 made of aluminum and a heating coil 6, and the end of the metal pipe 5 is hermetically sealed by caulking. . Note that the insulating filler 7 is made of acid [
It may also be made by adding silicone resin to hismagnesium powder.

を加熱により接合する。After placing the hot plate 1 in the electric furnace, the inside of the electric furnace is made into an inert 30 gas atmosphere, and a temperature of 510 to 600°C is maintained for 10 minutes to heat and melt the brazing filler metal 3.

状態が維持される。After this, the temperature of the hot plate 1 becomes a temperature at which thermal decomposition of the fluororesin 2 does not occur in the atmosphere, for example, about 400 degrees Celsius or lower35.
After that, the hot plate 1 is taken out from the electric furnace into the atmosphere. The above-mentioned inert gas means a N2 gas atmosphere, an Ar gas atmosphere, ammonia decomposition gas, D
It means a non-oxidizing atmosphere such as X gas. In the manufacturing method of the above embodiment, since the brazing filler metal 3 is melted in an inert gas atmosphere, thermal decomposition of the fluororesin 2 due to oxygen does not occur during this heating, and the initial surface treatment state is maintained. be done.

が熱分解されることがないものである。Note that when the insulating filler 7 is made of magnesium oxide powder with silicone resin added, the end of the metal pipe 5 is hermetically sealed to prevent foreign matter such as flux from entering when the brazing filler metal 3 is melted. In addition, it is possible to prevent the heat resistance of the silicone resin from deteriorating. As is clear from the above explanation, according to the present invention, since the sheathed heater is heated and bonded to the back of the hot plate, the fluororesin on the surface of the hot plate is not thermally decomposed. .
よつて表面処理の際の作業性が軽減されるとともに安定
性が増大する。Therefore, workability during surface treatment is reduced and stability is increased.
