Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a heating cooker that has a planar heating effect that is optimal for heating or keeping food warm.

(Prior Art) Conventionally, planar heating elements that generate heat over the entire surface are known and are used for various purposes such as floor heating, snow melting, and preventing freezing of pipes.

However, conventionally known planar heating elements have flexible properties and do not have rigidity by themselves, so it is necessary to form a heating cooker by forming only the planar heating element into a desired shape. I couldn't do that.
That is, in the past, the cooking device body was first formed into a predetermined shape using another material, and the planar heating element was pasted, buried, or attached to the inner surface of the preformed cooking device main body to form the cooking device main body. By integrating them, a heating cooker is constructed.

(Problems to be solved by the invention) This invention does not use the sheet heating element as a mere part of structures or equipment, but actually uses the sheet heating element itself to heat or keep food warm. It is an object of the present invention to make it possible to construct a structure to obtain a food product, and to also have a food covering or mounting function.

(Means for Solving the Problems) In order to solve the above problems, the means adopted by this invention are to cover both the front and back sides of the pure iron 2 with an insulating film 3,
4, the outer surface of one insulating film 3 is covered with a ceramic layer 5, the outer surface of the other insulating film 4 is covered with an aluminum foil layer 6, and the outer surface of one insulating film 3 is covered with an aluminum foil layer 6, and the outer surface of one insulating film 3 is covered with an aluminum foil layer 6.
A coating layer 7 of Teflon resin is provided on the outer surface of the aluminum foil layer 6, and a silicone resin layer 8 and a stainless steel foil layer 9 are sequentially provided on the outer surface of the aluminum foil layer 6 to form a plate-shaped heating material having a planar heating effect. It is characterized in that the heating material is formed into a desired shape while the coating layer 7 is on the surface close to the food to be cooked.

(Function) Silicone resin layer 8 and stainless steel foil layer 9 on the outer layer.
Since the heating material itself has rigidity, it can be formed into a desired shape such as a lid, plate, or tray by pressing or the like to manufacture a heating cooking device.

(Effects of the invention) According to this invention, since the planar heating material can be processed and directly molded into a desired shape, the cooking device can be manufactured easily and the cost can be reduced.

(Embodiment) Next, a preferred embodiment of this invention will be described with reference to the drawings. In the figure, 1 is a planar heating element that generates heat on its entire surface when energized; pure iron foil 2 is the heating element; insulating films 3 and 4 cover both sides of the pure iron foil 2; and one insulating film 3. A ceramic layer 5 covers the outer surface of the insulating film 4, and an aluminum foil layer 6 covers the outer surface of the other insulating film 4. Such a planar heating element 1 is conventionally known and easily available on the market. Such a sheet heating element generates far infrared rays, and is particularly effective in heating foods due to the molecular vibrational action of far infrared rays.

In this invention, the outer surface of the ceramic layer 5 of the planar heating element 1 is coated with Teflon resin to form a Teflon resin coating layer 7, the silicone resin layer 8 is formed on the outer surface of the aluminum foil layer 6, and the silicone resin layer 8 is formed on the outer surface of the aluminum foil layer 6. A stainless steel foil layer 9 is formed on the outer surface of the resin layer 8 to obtain a plate-shaped heating material which has rigidity and can be directly molded by press working or the like. When molding, the outer surface of the Teflon resin coating layer 7 is used as the surface close to the food and is formed into a shape such as a lid, a plate, a tray, etc. on which food can be covered or placed, thereby making the heating cooker. It is.

The silicone resin layer 8 insulates the outer surface (the surface away from the food) of the planar heating element 1, so the generated heat is concentrated toward the inner surface, making it possible to heat the food efficiently. Since the heat insulating layer is lightweight, combined with the lightweight stainless steel foil layer 9, the overall weight can be reduced. The stainless steel foil layer 9 imparts rigidity to the whole, gives a beautiful appearance, and increases impact resistance from other objects. The Teflon resin coating layer 7 formed on the inner surface prevents food from adhering to it and also from transferring odors. The presence of the Teflon resin coating layer 7, silicone resin layer 8, and stainless steel foil layer 9 makes it optimal for heating or keeping food warm.

Figures 2 and 3 show a planar heating element of this invention formed into a rectangular lid 10 with an open bottom surface, and a handle 1 at the center of the outer surface.
1 is attached.

Fig. 4 shows when cooking hamburger steak etc. on the iron plate 13 which is heated from the bottom with the burner 12.
The hamburger steak is heated by covering it with the lid 10 shown in Figs. 2 and 3 from above. Further, FIG. 5 shows a grill plate 14 with a built-in heater covered with a lid 10 for cooking okonomiyaki. In the heating cooking shown in Figures 4 and 5,
Since the food is heated from both the top and bottom, cooking time can be significantly reduced.

Figure 6 shows the planar heating element of this invention in tray 1.
