Abstract

PURPOSE:To remove a reflecting sheet by a method wherein the surface of a heat insulating material, produced through pressure molding after impregnating heat resistant resin into the surface of glass fibers, is coated with an aluminum foil and the aluminum foil is integrated with the heat insulating material by heat upon pressure molding while the aluminum foil is utilized as the reflecting sheet. CONSTITUTION:A heat insulating material 7 is formed by impregnating heat resistant resin or thermocuring crosslinking polycarbodiimide resin 6 of addition polymerization type, which utilizes carbodiimide (-N=c=N-) coupling, through pressure molding into the surface of glass fibers 5 while both sides of the heat insulating material 7 are coated by an aluminum foil 8, then, the heat insulating material 7 is integrated with the aluminum foil 8 through pressure molding whereby a reflecting plate used both for heat insulating material 4 can be formed.

In the case of the heating cooker having the above-mentioned configuration, it is necessary to combine the three separate parts of the reflecting plate, the heat insulating material and the holding plate as an assembly and fix them to the top plate of the heating chamber. However, there is a problem that the number of parts increases and the number of assembling steps increases, resulting in poor productivity.

The heating cooker of the present invention has been made in order to achieve the above-mentioned object. The surface of glass fiber is impregnated with a heat-resistant resin and the pressure-insulated heat-insulating material is coated with aluminum foil and pressed. The purpose of the present invention is to eliminate the reflector by integrating the aluminum foil with the heat insulating material by the heat of molding and using the aluminum foil as the reflector.

[0006]

In order to achieve the above object, the heating cooker of the present invention is provided with a heating chamber in the cooker body, and a heating element for grilling in the heating chamber. The heat insulating material is provided to prevent the heat of the heat transfer to the outer surface of the cooker body. The heat insulating material is obtained by impregnating the surface of the glass fiber with a heat resistant resin and press-molding the heat insulating material. The aluminum foil and the above-mentioned heat insulating material are integrated with each other by covering the foil with heat at the time of press molding to form a heat insulating material that also serves as a reflector.

[0007]

In the heating cooker having the above-mentioned structure, the aluminum foil and the heat insulating material are integrated into a heat insulating material that serves as a reflector, so that the number of parts can be reduced and the assembling process can be reduced to improve the assembling efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the heating cooker according to the present invention will be described with reference to FIGS. In the heating cooker of the present invention, the cooking chamber body 1 is provided with the heating chamber 2, and the heating element 3 for grilling is provided above the heating chamber 2, and the heat from the heating element 3 is applied to the heating chamber 2.
A heat insulating material 4 that also serves as a reflection plate that reflects light is provided.

The heat insulating material 4 which also serves as a reflector is formed on the surface of the glass fiber 5 by a carbodiimide (-N = C = N) which is a heat resistant resin.
-) Addition polymerization type thermosetting cross-linked polycarbodiimide resin 6 using a bond is impregnated and pressure-molded to form a heat insulating material 7, and both surfaces of the heat insulating material 7 are covered with aluminum foils 8 to form the heat insulating material. The material 7 and the aluminum foil 8 are press-molded to be integrated with each other to form the above-described reflector / heat insulating material 4. The temperature at the time of press molding is raised to a temperature at which the polycarbodiimide resin 6 can be melted, and the heat of this press molding causes the polycarbodiimide resin 6 to be used as a paste instead of the aluminum foil 8 on both surfaces of the heat insulating material 7 and to reflect the heat. The shape of the plate / heat insulating material 4 is formed.

The reflector / heat insulating material 4 is fixed to the top plate of the heating chamber 2 with screws 9. A door 1 for opening and closing a front opening of the heating chamber 2 on the front of the cooker body 1.
0, and the operation unit 11 is provided on the front surface of the cooker body 1.

With the above structure, the reflecting plate / insulating material 4 can be formed by the insulating material 7 and the aluminum foil 8, and the shape of the reflecting plate / insulating material 4 can be freely formed by press molding. Moreover, the heating chamber 2 can be attached to the top plate with a simple configuration.

[0012]

In the heating cooker of the present invention, the cooking chamber body is provided with a heating chamber, the heating chamber is provided with a heating element for grilling, and the heat from the heating element is transmitted to the outer surface of the cooking device body. An insulating material is provided to prevent the heat-insulating material from being formed by impregnating the surface of the glass fiber with a heat-resistant resin and press-molding the surface of the heat-insulating material with an aluminum foil to heat the aluminum during press molding. Since the foil and the heat insulating material are integrated to form the reflector and heat insulating material, it is possible to reduce the number of parts, reduce the assembly process, and improve the assembly efficiency.
An aluminum foil can be used as a reflector without using a conventional reflector, and the material cost can be reduced.
