Description

TECHNICAL FIELD

[0001] The present disclosure relates to a field of washing machines, for example, it relates to a washing machine tub and a washing machine.

BACKGROUND

[0002] With the popularization of washing machines, the manufacturers are paying more and more attention to reducing costs and increasing efficiency while enhancing the functions and aesthetics of the washing machines. On one hand, they continue to develop new functions of products, and on the other hand, they pay more attention to the improvement based on related products. When new structures and processes are adopted, the products become material-saving and have higher structural strengths, and can be easily produced and suitably assembled, thereby minimizing costs of raw materials and production cost of the product, so that an overall competitiveness of the products is improved.

[0003] The tub of a roller washing machine is usually made of a material of a steel plate having a thickness range of 0.6 mm-0.7 mm, and a tub formed by the front plate body, the rear plate body and the plate bodies at both side is formed. The tub mainly provides a function to support internal components, such as an inner drum, an outer drum, and the control panel, etc., and connect an outer housing simultaneously. In order to meet the requirements of installing the internal components, one of the panels can be opened.

[0004] For a large-capacity washing machine, the size of the tub is increased. Under the condition that the thickness of the steel plate of the tub is not directly increased, it is objectively required to improve the structure of the tub, so that the tub can have a higher overall strength and avoid the vibration and noise caused after the tub is assembled, which meets the requirements of production, transportation and use.

DETAILED DESCRIPTION

[0018] A description for the present disclosure is given as follows by showing selectable embodiments. In a case of no conflicts, the embodiments and the features in the above embodiments can be arbitrarily combined.

[0019] As shown in FIG. 1 and FIG. 2, a composition structure of a washing machine tub is shown. The tub includes a front plate 3 and a tub body having a U-shaped cross section and formed by two side plates 1 and a rear plate 2. The tub body is formed by integrally pressing a piece of steel with a thickness range of 0.6 mm to 1.2 mm. For enabling the tub to have a higher strength and meet a requirement for supporting the inner components of the washing machine, convex blocks 12 can be pressed on the side plate 1 and the rear plate 2 at the same time, concave blocks also can be pressed, or both the convex blocks and the concave blocks are pressed, all of which can serve to reinforce the box.

[0020] For the present embodiment, the front plate 3 can be separately formed by pressing an entire plate. In one embodiment, for integrally forming a complete washing machine tub by assembling and combining the tub body, the tub body and the front plate 3 are manufactured with a main body flange 4 and a front plate flange 5 respectively on the binding ends. The main body flange 4 and the front plate flange 5 are respectively provided with protruding ribs and grooves along the length direction, and the protruding rid can fall into the grooves to form a matching. For the present embodiment, it is an option that a groove 8 is pressed on the main body flange 4, and the shape of the cross section of the groove 8 is an arc shape as shown in FIG. 5. A protruding rib 9 is pressed on the front plate flange 5 of the front plate, and the shape of the cross section of the groove 9 is an arc shape as shown in FIG. 6. The corresponding groove 8 and protruding rib 9 form a pair and have an identical shape. When the assembly and the combination are performed, as shown in FIG. 7, the protruding rib 9 falls into the groove 8, and the corresponding protruding rib 9 and groove 8 reinforce the rigidity of the front plate flange 5 and the main body flange 4 in the vertical direction, and can achieve a limit in a horizontal direction after the tub is combined and assembled, which solves a problem of left and right misalignment and swing caused after a large-sized tub is produced and assembled with a thin plate, increases the overall strength of the tub to avoid the vibration and the noise caused by the deformation of the tub after it is assembled, and meets the requirements for the production, the transportation and the use of a large-sized washing machine without increasing the thickness of the used material.

[0021] As shown in FIG. 1 and FIG. 2, on the tub described in this embodiment, the tub main body and the upper portion of the binding ends of the front plate are sequentially formed with a protruding strut 6 and a hanging hole 7 to form a locking structure, and the lower portion of the binding end is provided with the screw holes 10 and 11 for performing a fastening with the screws. A cooperation structure of the protruding rib 9 and the groove 8 is provided in the middle of the binding end.

[0022] In one embodiment, an assembled locking structure is as shown in FIG.3 and FIG. 4, and a protruding strut 6 is disposed on the main body flange 4. A longitudinal section of the protruding strut 6 perpendicular to a plane in which the protruding strut 6 is disposed in a "T" shape. The hanging hole 7 is opened in the front plate flange 5 correspondingly, and it is an opening with a small upper end and a large lower end. It can be formed in a combination of an upper rectangular hole and a lower oblong hole as shown in the figures. At the time of assembly and combination, the protruding strut passes through the large end of the hanging hole 7 and slides to a small end to form a locking so that the front plate 3 hangs on the tub body and cannot be pulled out. Meanwhile, since a height from a lower surface of a "T" shape of the protruding strut to an upper surface of the main body flange 4 is slightly larger than a thickness of the plate at the opening of the hanging hole, the front plate 3 and the tub body form a locking at the binding end. A screw is inserted into the screw holes 10 and 11 at the lower portion part so as to form a locking of the lower portion of the binding end, and at the same time, the protruding rib 9 falls into the groove 8 to form a matching.

[0023] The above assembling manner replaces the conventional manner of fastening with the screw and the screw hole. During assembly, the front plate can be easily mounted firstly and locked on the protruding strut to form a combination of the tub body and the front plate, and afterwards, it is fastened. The assembling is simple and easily performed, and there is no requirement for assisting other measures to make the two together. As a result, time and efforts are saved, and the assembly efficiency is improved.

[0024] The washing machine adopting the above tub has higher ergonomics in the production and assembly process, and at the same time, has a more solid and stable overall structure, which satisfies the reliability requirements for production, transportation and use in mass production.

[0025] The foregoing embodiments are merely optional embodiments of the present disclosure, and do not constitute limitations on the scope of protection of the present disclosure. Any implementation manner falling within the protection scope of the present disclosure constituted by the features or equivalent features of the present disclosure infringes the patent right of the present disclosure.
