DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller case of an electric warming device having a sheet film adhered to an upper surface thereof.

[0002]

2. Description of the Related Art Conventionally, a controller case of an electric warming device has a structure as shown in FIGS. Hereinafter, the configuration will be described with reference to the drawings. As shown in the drawing, a controller case (not shown) of the controller (not shown) that controls the energization of the electric warming device main body 1 includes a controller upper case 2 and a controller lower case 3, and a flat portion 5 on the upper surface side of the controller upper case 2. And a sheet film 4 is adhered to the concave portion with an adhesive, and is assembled integrally with the controller lower case 3.

[0003]

However, in the above-mentioned conventional configuration, if the sheet film 4 is adhered to the curved surface portion 6 of the controller upper case 2 in order to change the design, the film 4 comes off during use. Therefore, there was a problem that it could be stuck only to the flat part 5. That is, when the sheet-like film 4 is adhered to the curved surface portion 6 of the controller upper case 2, a residual stress caused by bending the sheet-like film 4 remains, and the adhesive strength of the adhesive at the end 7 of the sheet-like film 4. Is reduced, and the end 7 of the sheet-like film 4 comes off in an attempt to restore the sheet-like film 4.

The present invention solves the above-mentioned conventional problems. Even when a sheet-like film is adhered to a curved surface portion of a controller upper case, the end portion is not peeled off and can be securely adhered to a flat portion and a curved surface portion. An object of the present invention is to provide a controller case for an electric heating device.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned conventional problems, and comprises a box-shaped controller lower case having an opening on the upper surface, a box-shaped controller upper case having an opening on the lower surface, and A sheet film adhered to the outside of the controller upper case, wherein the sheet film is adhered to an opening edge of the controller upper case, and the sheet film is attached to an opening edge of the controller lower case. A projection is provided to cover the end of the film.

[0006]

In the above construction, the end of the sheet-like film is covered with the projection and clamped, so that the sheet-like film does not come off.

[0007]

1 and 2 show an embodiment of the present invention.
This will be described with reference to FIG. In this embodiment, the same components as those shown in the above-described conventional example are denoted by the same reference numerals, and the description thereof will be omitted. The characteristic configuration of this embodiment is that a protrusion is provided on the controller lower case described in the conventional example. That is, the sheet-like film 4 is adhered to the flat surface portion 5 and the curved surface portion 6 on the upper surface side of the controller upper case 2, and is covered with the projections 10 provided on the controller lower case 9 so as to cover the end 7 of the sheet-like film 4. It is what I wore.

In the above construction, when the sheet film 4 is adhered to the flat portion 5 and the curved portion 6 on the upper surface side of the controller upper case 2 by providing the projections 10 on the controller lower case 9, the controller lower case 9 is provided. Since the projections 9 of the sheet 9 cover and sandwich the end 7 of the sheet-like film 4, they do not come off.

[0009]

As is apparent from the above embodiment, according to the controller case of the electric warming device of the present invention, the projections are provided on the controller lower case, so that the controller upper case has a flat surface portion and a curved surface portion on the upper surface side. When sticking the sheet-like film, the projections cover the end of the sheet-like film and are pinched, so it does not peel off, and the flat and curved parts on the top side of the controller upper case can be used effectively, and the design The degree of freedom can be expanded.
