Description

  The present invention relates to an electric device, and more particularly to a structure for displaying a logo, a pattern, or the like on the surface of a housing.

Among electrical equipment, for example, an air conditioner adds hot stamping foil with a metal coating layer on a film to the surface of a resin suction grille that forms the front of the enclosure with a rubber stamp with a logo or pattern. Some of them have a decorative portion that is heat-transferred (hereinafter referred to as a hot stamp) by pressure heating.
However, since the hot grill is directly stamped on the suction grill, when the hot stamp is broken, the suction grill, which is a large component, must be discarded, resulting in a poor yield and an impact on product cost. In addition, when the user cleans the surface of the suction grill, the hot stamping foil on the decorative part is damaged by rubbing with a brush, or the metallic feeling of the hot stamping foil is rubbed by wiping with a detergent, thereby impairing the design. The problem that occurred.

An air conditioner that solves this problem is one in which a small rectangular parallelepiped decorative part provided with a decorative part made of hot stamp foil is attached to a recess formed in a suction grill (for example, see Patent Document 1).
In this air conditioner, hot stamping is applied to decorative parts that are separate parts without direct hot stamping on the suction grill, so even if the hot stamping is broken, only the decorative parts need to be discarded to improve the yield. Is done. In addition, the decorative part is attached to the bottom wall of the recess formed in the suction grille, and the hot stamping foil of the decorative part is disposed at a position behind the surface of the suction grille so that the surface of the suction grille can be cleaned. Hard to scratch or rub hot stamp foil.

  However, in the air conditioner of Patent Document 1, since the suction grill and the decorative part are separate parts, when the suction grill is viewed from the front, a contour line of the recess of the suction grill and the outline of the decorative part around the decorative part. Because of this, there is a problem that it is not possible to simply express the decorative part without the outline.

JP 2008-215687 A

  In view of the above-mentioned problems, the present invention provides a high yield of the casing and is less likely to be scratched on the surface of the casing even when a decorative portion such as a logo or a pattern is directly provided on the surface of the casing, and a high-quality design can be obtained. The purpose is to provide electrical equipment.

  In order to solve the above-described problems, the electrical device of the present invention includes a decorative plate in which a hole is formed in a part of the surface according to the outline of a display pattern such as a logo or a pattern, and a hole attached to the back of the decorative plate. And a decorative part composed of a decorative plate provided with a projection sheet that is provided with a projection hole corresponding to the projection of the mounting plate, and is decorated on the projection of the mounting plate. The attachment plate is attached to the decorative plate so as to fit the protrusion hole of the sheet and sandwich the decorative sheet.

  According to the electric device of the present invention, the decoration part is configured by the combination of the hole formed in the decoration plate, the projection provided on the attachment plate, and the decoration sheet. Even if a display pattern such as a picture or a picture is provided, the yield is improved because a hot stamp is not applied to the decorative board. In addition, since the depth of the punch hole can be increased by the thickness of the decorative plate, the decorative sheet sandwiched between the decorative plate and the mounting plate is less likely to be scratched, and looks like a three-dimensional display pattern. Can be given. Further, since the protrusion hole is formed in the decorative sheet in accordance with the protrusion of the mounting plate, the decorative sheet can be prevented from being displaced when the decorative sheet is sandwiched between the decorative plate and the mounting plate.
