DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, a heat insulating front panel 1 comprises a surface decorative sheet 2 formed of a synthetic resin thin plate, and a back surface portion 4 of the surface decorative sheet 2 filled with expanded polystyrene. A synthetic resin foam material layer 5 formed by foaming beads 6 is integrally formed and configured. The top edge portion 10 of the synthetic resin foam material layer 5 in which the edge portion 3 of the surface decorative sheet 2 is bent upward by a predetermined length and is further folded back to be lined with the back surface portion 4 of the surface decorative sheet 2. A folded-back portion 11 having a substantially U-shaped cross section is formed so as to wrap it for a predetermined length. In this way, the surface decorative sheet 2 is formed in a substantially dish shape, and the back surface 4 thereof is lined with the synthetic resin foam material layer 5 over the entire surface.
Are held by the folding part 11. Further, the heat insulating surface panel 1 is attached so that the surface portion 8 thereof faces the room.

As a method of manufacturing the heat insulating front panel 1, first, a synthetic resin thin plate material is vacuum formed into a surface decorative sheet 2, and an edge portion 3 thereof is bent upward by a predetermined length to form a plate. Synthetic resin foam material layer 5 after being formed into a shape
It is placed in a mold for molding. Further, while keeping the surface decorative sheet 2 side at a low temperature, Styrofoam beads 6 are injected into the mold of the surface decorative sheet 2 formed in a substantially dish shape, and heated only from the upper surface portion 7 of the surface decorative sheet 2. To do. Then, the beads 6 gradually foam and melt from the upper surface portion 7 of the surface decorative sheet 2. Therefore, when the foaming and melting of the beads 6 reaches the vicinity of the back surface portion 4 of the surface decorative sheet 2, the heating is stopped and the edge portion 3 is further folded inward to form the folded portion 11 having a U-shaped cross section. Then, the upper edge portion 10 of the synthetic resin foam material layer 5 is wrapped by a predetermined length and held by the folded portion 11, and the synthetic resin foam material layer 5 is lined over the entire back surface portion 4 of the surface decorative sheet 2. As a result, the heat insulating front panel 1 is formed.

Next, the operation of this embodiment will be described.
