DETAILED DESCRIPTION
[0024] 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.
[0025] 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.
[0026] 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.
[0027] 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.

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.
[0029] 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.
[0030] 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.
[0031] 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.
INDUSTRIAL APPLICABILITY
[0032] The embodiments of the present disclosure provide a washing
machine tub and a washing machine. As for washing machine tub, the

in a vertical direction and achieve a limit in a horizontal
direction after the tub is combined and assembled, which solves the
problem of left and right misalignment 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
