Description

[Detailed Description of the Invention] The present invention relates to a washing machine having an outer frame made of a metal plate attached to a base made of resin.

When attaching the outer frame to the base, form a flange piece on the lower opening edge of the outer frame as well as a hanging piece, place the flange piece on the mounting piece of the base, and place a hanging piece on the inner side of the base. , and in this state, secure the flange piece and mounting piece with bolts or the like. Deep cuts are made in each corner of the hanging piece to facilitate the bending process.
The hanging piece was broken at this corner. When such an assembly is subjected to a drop test, the corners of the base and outer frame may be damaged, displaced from each other, or damaged due to the impact of the fall, since the strength of the corners is inevitably reduced. The paint on the corners of the frame sometimes fell off. Therefore, in the past, the outer frame was made thicker to pass the drop test. The present invention improves the strength at the corners and makes it suitable, and allows the outer frame to be constructed from a thin metal plate, and will be explained below with reference to the drawings.

Reference numeral 1 denotes an outer frame of a washing machine formed by bending a metal plate into a rectangular tube shape, and a horizontal collar piece 2 is bent inward at the lower opening edge, and the inner end of the collar piece 2 is bent inwardly. A hanging piece 3 is formed by bending. The hanging pieces 3 are also formed continuously at the four corners of the outer frame, but in order to facilitate press working, the parts corresponding to the four corners are cut in advance and bitten into the flange piece 2. As a result, the four corners A continuous curl portion 4 is formed in a bulging manner. Further, the wrinkles that inevitably occur on the surface of the curled portion 4 during processing are reduced by cutting the material in advance and bulging it at the corners as described above.

5 is the base of the washing machine, which is made of resin and molded into a box shape.
A placing piece 6 is formed on the edge of the upper opening facing outward, legs 7 are provided protruding from the lower surface of the four corners, and recesses 8 are provided at the corners of the placing piece 6 so as to project downward. is forming.

Next, to explain the work of attaching the outer frame 1 to the base 5, the collar piece 2 of the outer frame 1 is placed on the mounting piece 6 of the base 5, and the hanging piece 3 is inserted inside the base 5. .
The curled portion 4 of the hanging piece 3 is fitted into the recess 8, and the wavy outer surface is pressed into contact with the inner surface of the recess 8 so as to partially bite into it. Then, the flange piece 2 of the outer frame 1 and the mounting piece 6 of the base 5 are fastened together with bolts or the like.

In this way, the washing machine according to the present invention, when attaching the outer frame to the base, forms the hanging pieces of the outer frame continuously without cutting them at the corners, and at the same time curls the curled parts outward at the corners. Since the corner of the mounting piece of the base is formed to bulge out, and a recess into which the curled part is fitted is formed in the corner, the strength of the corner can be greatly improved, and compared to the conventional method. Since it can withstand the drop test of

Furthermore, since the bulging curled portion is fitted into the recess, positioning during the installation work can be easily performed.
