detailed description

The present invention will be further described below by specific examples.

As shown in Figures 1 to 2, the composition structure of a washing machine box is shown. The box body includes a box body with a U-shaped cross-section formed by two side panels 1 and a rear panel 2 and a front panel 3. The box body adopts A piece of steel plate with a thickness of 0.6mm to 1.2mm is integrally pressed and formed. In order to make the box body have higher strength and meet the support for the components inside the washing machine, the protrusions 12 are pressed on the two side plates 1 and the rear plate 2 at the same time. Pressing it into a concave block, or having a convex block and a concave block at the same time, can all play a role in strengthening the box body.

For this embodiment, the front plate 3 is also separately pressed and formed by the whole plate. In order to meet the requirements of its assembly and combination with the aforementioned box body to form a complete washing machine box, the box body and the front plate 3 are separately processed on the joint end. There are main body flanging 4 and front plate flanging 5. On the above flanging, ribs and grooves are respectively arranged along its length direction, and the ribs can fall into the grooves to form fit. For this embodiment, specifically, a groove 8 is pressed on the main body flange 4, and its cross-sectional shape is an arc shape as shown in Figure 5; a convex rib 9 is pressed on the front plate flange 5, and its cross-sectional shape is As shown in Figure 6, it is also in the shape of an arc, and the corresponding groove 8 and rib 9 form a pair and have a matching shape. When assembling and combining, as shown in Figure 7, the rib 9 falls into the groove 8, The corresponding convex ribs and grooves strengthen the stiffness of the flange in the vertical direction, and at the same time, it can realize the limit position in the horizontal direction after the box is combined and assembled, which solves the left and right problems caused by the production and assembly of large-sized boxes in the past. Misaligned shaking enhances the overall strength of the box, avoids vibration and noise caused by deformation of the box after assembly, and can meet the production, transportation and use requirements of large-sized washing machines without increasing the thickness of materials.

As shown in Figures 1 to 2, on the box body described in this embodiment, the upper part of the joint end of the main body of the box body and the front plate is provided with a boss 6 and a hanging hole 7 to form a locking structure, and a screw hole 10, 11 Cooperate with the screw for fastening, and the above-mentioned convex rib 9 and the groove 8 are arranged in the middle of the joint end.

The specific assembly and locking structure is shown in Figures 3 to 4. The protruding post 6 is arranged on the main body flange 4. The longitudinal section of the protruding post 6 perpendicular to the flange plane is in the shape of a "T", and the hanging hole 7 is correspondingly opened on the front plate. On the flange 5, there is a small opening at the upper end and a large opening at the lower end. As shown in the figure, a combination of a rectangular hole at the upper end and an oblong hole at the lower end can be used. end, so that the front plate 5 is hung on the main body of the box body and cannot come out. At the same time, because the height from the lower surface of the "T" character of the convex column to the surface of the flange 4 of the main body is slightly greater than the thickness of the plate at the opening of the hanging hole Finally, the front plate 5 and the box body are locked at the upper part of the joint end; screw holes 10 and 11 in the lower part are used to lock the lower part of the joint end, and the ribs 9 fall into the groove 8 to form a fit.

The above-mentioned assembly method replaces the traditional way of fastening with screws and screw holes. During assembly, the front panel can be easily hung and locked on the boss to form the assembly combination of the main body and the front panel. Afterwards, fastening is performed, and the assembly is simple and easy, without the need for other measures for assembling and combining the two, which saves time and effort, and improves the assembly work efficiency.

The washing machine using the above-mentioned cabinet has higher work efficiency in the production and assembly process, and has a more solid and stable overall structure, which meets the reliability requirements of production, transportation and use in the mass production process.

It should be pointed out that the above-mentioned embodiment is only a preferred implementation of the present invention, and does not constitute a limitation to the protection scope of the present invention. All constitute infringement of the patent right of the present invention.
