CONSTITUTION:At the time of attaching a decorative sheet 7 into a recessed part 13, engaging pieces 9... are engaged to engaging holes 17..., turned by using them as supporting points, and detaining claws pieces 10... are detained to detaining holes 15.... Fitting pieces 11, 11 are fitted into fitting holes 16, 16 simultaneously with attachment in order to obstruct shakiness in the vertical direction of the decorative sheet 7, and since these fitting pieces 11, 11 are provided with circular arc surfaces 12, 12, the fitting work is guided smoothly. Also, since inclined surfaces 8, 8 are provided on the end part of the decorative sheet 7, when the decorative sheet 7 is turned in order to attach it, it does not occur that the end part of the decorative sheet 7 is caught in the recessed part 13.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a washing machine.

(B) Conventional technology As a conventional example, a washing machine has a recess formed in the outer edge of the upper part of the machine frame in which the washing tub is installed, and a decorative board is disposed inside the recess.
Publication No. 57-54371 (Do 6 F 39/
12).

(c) Problems to be Solved by the Invention In the conventional example, the decorative board is provided only on the front of the machine frame, so the joint between the decorative board and the recess is exposed at the corner of the machine frame. , Impairing the aesthetic appearance - L. The decorative board and recesses were sometimes deformed due to changes in temperature, causing the decorative board to wobble.

The present invention relates to improvements in washing machines and is intended to solve these problems.

(D) Means for Solving the Problems The present invention provides a washing machine in which a recess is formed in the upper 5'l edge of a machine frame in which a washing tub is installed, and a decorative board is disposed within this recess. The recess is configured to extend from the front surface to both side surfaces of the machine frame, an engaging hole is provided at the lower front of the recess, a locking hole is provided at the upper part, and further, both ends of the recess are provided. A fitting hole is provided in the opposite direction, and the decorative plate is formed in a U-shape to match the shape of the recess. A locking claw piece that locks in the locking hole when the locking piece is rotated as a fulcrum and a fitting piece that fits in the fitting hole are formed, and further, both ends of the decorative board are formed. The upper corner portion and the upper corner portion of the fitting piece are formed into an obtuse angle or an arc shape.

(E) Effect: Since the decorative board is shaped to span both sides of the machine frame, the joint between the decorative board and the end faces of the recess cannot be seen from the front.

Further, due to the fitting relationship between the fitting hole and the fitting piece, the decorative board is difficult to move in the vertical direction. In addition, by making the upper corners of both ends of the decorative board and the upper corner of the fitting piece obtuse or arcuate, the decorative board and the fitting piece can be easily attached when the decorative board is rotated and attached. The corners of the pieces are less likely to get caught in recesses or fitting holes.

(f) Example Embodiments of the present invention will be described based on the drawings.

In FIGS. 1 to 4, 1 is a frame of a two-tub type washing machine, and the front surface 1a thereof is shaped to bulge slightly outward. Inside the machine frame 1, there are provided a washing tub 2 made of molded polypropylene and an outer dehydration tub (not shown). In addition, a 7-run section 3 having an inverted cross section is integrally formed along the upper end opening of the washing tW2 and the outer dehydration tank, and this 7-run section 3 is placed on the upper end of the machine frame l and secured with screws.
