Benefits of technology

[0010]In view of the above-described problems, the present invention has an object of providing an outer cabinet which allows a material to be affixed to maintain its bonding reliability and to be removed therefrom efficiently and easily, and also providing an electrical appliance using the cabinet.
[0013]The outer cabinet and an electrical appliance using the cabinet according to the present invention allow a material to be affixed to maintain its bonding reliability and to be removed from the cabinet efficiently and easily.

Problems solved by technology

When such a plastic molded product is recycled as plastic, the material to be affixed is required to be removed therefrom, but that is not easy.
Removing the material to be affixed from the recess requires workers to use edged tools, thus taking man-hours and causing a safety concern.
It is difficult, however, to punch it as accurately as desired because plastic molded products come in various shapes.
In the outer cabinet of this Patent Literature, however, the non-through holes are partly not in contact with the material to be affixed, thus causing the material to be affixed to peel off from the non-contact regions, and hence, to have low bonding reliability.
As another problem, pushing the edges of the material to be affixed is not enough to remove the whole of it because it is formed thin using such as metal plate, aluminum foil, plastic, or paper.
As still another problem, it is difficult to remove the material to be affixed precisely enough not to leave the adhesive on the plastic molded product.

first embodiment

[0025]In a first embodiment, the electrical appliance is described as a liquid crystal display TV, and the outer cabinet is used as the backcover of the TV.

[0026]FIG. 1 is a perspective view of outer cabinet 10 according to the present first embodiment. Outer cabinet 10, which acts as the backcover of the liquid crystal display TV, includes affixing portion 40 at its center on which to affix nameplate 20 as a material to be affixed.

[0027]FIG. 2A shows affixing portion 40 viewed from affixing surface 30 (in the positive direction of the x axis of FIG. 1). FIG. 2B shows affixing portion 40 viewed from rear surface 70 (in the negative direction of the x axis of FIG. 1). FIG. 3 is a sectional view of affixing portion 40 taken along a line 3-3 of FIG. 2A. In FIGS. 1 to 3, outer cabinet 10 is a plastic molded product.

[0028]Outer cabinet 10 includes affixing surface 30 on which nameplate 20 is affixed as a material to be affixed. Affixing surface 30 includes affixing portion 40 having rece...

second embodiment

[0047]An outer cabinet according to a second embodiment of the present invention will be described as follows. Like the first embodiment, the outer cabinet is used as the backcover of a liquid crystal display TV. The outer cabinet of the second embodiment differs from that of the first embodiment in the structure of the inner groove portion.

[0048]Like components are labeled with like reference numerals with respect to the first embodiment, and the description thereof will be omitted.

[0049]FIG. 5A shows affixing portion 40 viewed from affixing surface 30 (in the positive direction of the x axis of FIG. 5A). FIG. 5B shows affixing portion 40 viewed from rear surface 70 (in the negative direction of the x axis of FIG. 5B). FIG. 6 is a sectional view of affixing portion 40 taken along a line 6-6 of FIG. 5A.

[0050]Affixing portion 40 includes inner groove portion 90 including through grooves penetrating from affixing surface 30 to rear surface 70. More specifically, inner groove portion 9...

Abstract

An outer cabinet and an electrical appliance using the cabinet include an affixing surface on which a material to be affixed is affixed. The affixing surface includes an inner groove portion inside the outer peripheral edge of a nameplate as the material to be affixed. The rear surface, which is on the opposite side of the affixing surface, includes an outer groove portion in the vicinity of the position opposite to the outer peripheral edge of the nameplate.

Description

BACKGROUND OF THE INVENTION[0001]1. Filed of the Invention[0002]The present invention relates to an outer cabinet that can be effectively used as recyclable resources, and to an electrical appliance using the cabinet.[0003]2. Background Art[0004]Electrical appliances such as audio / video equipment, computer terminals, and office automation equipment are required to affix a material such as a nameplate or a seal thereto, usually on the outer cabinet thereof. The materials to be affixed, which are made of metal, plastic, paper, or other types of materials, show the product name, the product number, the manufacture, and other information. Nameplates are commonly made of metal or plastic, and seals are often made of paper. Outer cabinets generally are plastic molded products or metal molded products.[0005]The material to be affixed is fixed on a plastic molded product in such a manner as to prevent its peeling off and at the same time not to spoil the appearance. More specifically, the p...
