Description
TECHNICAL FIELD
[0001] The present disclosure belongs to the field of household
appliances, and in particular relates to a washing tub for a
washing machine and a washing machine provided with the same.
BACKGROUND
[0002] A washing machine is designed as a device for washing
laundry through the use of electricity. Generally speaking, a
washing machine includes: a tub for holding washing water; a
rotating tub, rotatably mounted inside the tub; an impeller,
rotatably mounted at the bottom of the rotating tub; a motor and a
clutch, configured to drive the rotating tub and the impeller to
rotate. When the rotating tub and the impeller rotate in a state in
which laundry and a detergent are introduced into the rotating tub,
the impeller agitates washing water together with laundry
introduced into the rotating tub, thereby removing stains from
laundry. In order to increase the washing capacity of a washing
machine, a larger rotating tub is required, i.e. the height or
diameter of the rotating tub needs to be increased. If the rotating
tub has a larger size, the tub accommodating the rotating tub and a
casing accommodating the tub also need to be increased as the
rotating tub increases. While in the washing process of the
conventional pulsator washing machine, the inner and outer tubs are
communicated with each other, with water in both the inner and
outer tubs, but only water in the inner tub is actually used for
laundry washing, resulting in water wasting. Moreover, during
long-term use, dirt accumulates between the inner tub and the outer
tub, bacteria grow, and the water exchange process between the
inner tub and the outer tub causes secondary contamination to the
laundry, so that draining of the washing water inside the washing
tub in time and avoiding contamination of the inner space of the
washing machine become problems to be solved urgently.
[0003] The Chinese patent with the application number
CN201621037656.1 discloses a pulsator washing machine, including: a
non-porous inner tub, a sealing disc and a driving device, the
bottom of the non-porous inner tub is provided with a drain hole.

bottom of the non-porous inner tub between an open position and a
closed position relative to the non-porous inner tub, the sealing
disc is provided with a water passing hole, the water passing hole
is communicated with the drain hole when the sealing disc is in the
open position, the sealing disc closes the drain hole when the
sealing disc is in the closed position, and a sealing plate is
located on the inner side of the bottom of the non-porous inner
tub. The driving device is connected with the sealing disc and the
non-porous inner tub, and is used for driving the non-porous inner
tub and the sealing disc to rotate and driving the sealing disc to
rotate relative to the non-porous inner tub.
[0004] The Chinese patent with the application number

[0122] As shown in FIGS. 1 to 10, a washing tub 1 for a washing
machine according to the present disclosure includes a body of the
washing tub 1, wherein a dewatering port 3 is formed in the top of
the tub wall of the washing tub 1 and is configured as an opening
structure for guiding out washing water in the washing tub 1, a
water guide structure 2 for guiding washing water in the washing
tub 1 to a water receiving device 6 at the lower part of the
washing tub 1 is arranged corresponding to the dewatering port 3,
the water guide structure 2 is arranged on the tub wall of the
washing tub 1 and communicated with the dewatering port 3. Due to
the capacity enlargement of the washing machine, in the dewatering
stage, water is drained from a dewatering port into a water
channel. According to the present disclosure, the dewatering port 3
of the washing tub 1 is formed in the tub wall of the washing tub
1, and simultaneously the water guide structure 2 is communicated
with the dewatering port 3, the flowing trend of the water flow
during dewatering of the washing tub 1 is effectively utilized, and
the energy consumption is reduced while the function is
guaranteed.
[0123] As shown in FIGS. 1 and 2, in order to enlarge the capacity
of the washing tub 1 to accommodate more laundry in the process of
washing operation, an outer tub originally arranged outside the
washing tub 1 is omitted. Without the outer tub, water drained from
the water channel enters a drainage trough at the bottom, the
capacity of the washing tub 1 is required to be enlarged, and the
height of the drainage trough is limited. The water level in the
drainage trough is of a certain height, when the inner tub rotates
at a high speed for dewatering, the shape structure of the water
channel directly influences the water splashing degree. Therefore,
the water guide structure 2 is arranged on the outer wall of the
washing tub 1. Meanwhile, the water guide structure 2 mainly
includes an arc-shaped outer wall 201 arranged at the end far away
from the washing tub 1 and an inner wall 202 arranged at the end
near the washing tub 1. The inner wall 202 is closer to the washing
tub 1, the radius of the outer wall 201 is smaller than the radius
of the inner wall 202, the radius of the outer wall 201 is smaller
than the radius of the inner wall 202 of the washing tub 1, i.e.
the radius of the outer wall 201 is smaller than the radius of the
washing tub 1. By setting the outer wall 201 of the water guide
structure 2 in a large circular arc shape, the contact area between
the water guide structure 2 and water during dewatering is reduced,
it is ensured that washing water can be drained from the water
guide structure 2 more quickly. In order to prevent washing water
from overflowing via the gap between the dewatering port 3 and the
water guide structure 2 during washing and dewatering operations of
the washing tub 1, a sealing structure is arranged between the tub
wall of the washing tub 1 and the water guide structure 2, and the
sealing structure can effectively prevent washing water from
splashing via the gap between the tub wall of the washing tub 1 and
the water guide structure 2.
[0124] As shown in FIGS. 1 to 5, the washing tub 1 according to the
present disclosure is configured, during washing process, as a tub
body for holding washing water. The portion, located below the
dewatering port 3, of the tub wall of the washing tub 1 is
impermeable, which guarantees that the washing tub 1 is in a
non-porous state. Due to this arrangement, the structure of the
outer tub is omitted, an inner tub is used as a main body for
holding laundry and washing water, and the capacity of the washing
tub 1 is increased under the condition that the overall washing
machine capacity does not change or changes very little, a capacity
enlargement effect of the washing machine is achieved. A
conventional washing machine requires to be provided with an outer
tub, and the corresponding washing and dewatering process can be
done by cooperating use of the outer tub with the inner tub. Thus,
stains may remain between the outer tub and the inner tub, and it
is disadvantageous to health after long-time use of the washing
machine. Water is only stored in the washing tub 1 during washing
process according to the present disclosure, so that the problem of
"keeping dirt" of the inner wall 202 of the outer tub and the outer
wall of the washing tub 1 caused by water storage between the inner
tub and the outer tub of a conventional washing machine is solved,
and a better washing effect is achieved. Meanwhile, the outer tub
is omitted and the washing tub 1 is used as the water holding tub,
so that no water is stored between the inner tub and the outer tub
during washing, thereby reducing the amount of washing water and
saving washing water.
[0125] Further, according to the present disclosure, the water
guide structure 2 is embedded in the outer wall of the washing tub
1, such arrangement improves the service life of the washing tub 1,
and also facilitates maintenance and replacement. Preferably, the
water guide structure 2 and the outer wall of the washing tub 1
form a smooth transition curved surface, and the smooth transition
curved surface can effectively reduce wind resistance, reduce
energy consumption and improve washing efficiency when the washing
tub 1 rotates at a high speed.
[0126] As shown in FIGS. 4 and 5, in order to further guarantee the
effect of drainage, the water guide structure 2 according to the
present disclosure further includes a first water guide portion 4
which is closely attached to the outer side of the tub wall of the
washing tub 1, the outer wall 201 of the first water guide portion
4 cooperates with the outer wall of the washing tub 1, i.e. the
inner wall 202 of the first water guide portion 4, to form a water
guide chamber structure for guiding washing water out of the
washing tub 1. The benefit of such arrangement is that when the
washing machine is in dewatering operation, in a high-speed
rotation state of the washing tub 1, if there are too many
constituent parts of the washing tub 1, during the rotation,
vibration will be generated, and further noise is generated and the
user's experience and sense will be affected to a certain degree.
The water guide structure 2 cooperates with the outer wall of the
washing tub 1 to form a water guide chamber, thus omitting the
procedure of secondary processing and improving the service life of
the washing tub 1 and improving the resistance to vibration noise
of the washing machine at the same time.
[0127] As shown in FIG. 8, in order to prevent washing water from
overflowing via the dewatering port 3 and the gap of the water
guide structure 2 during washing and dewatering operations of the
washing tub 1, a sealing structure 9 is arranged between the tub
wall of the washing tub 1 and the water guide structure 2. And the
sealing structure 9 can effectively prevent washing water from
splashing via the gap between the tub wall of the washing tub 1 and
the water guide structure 2.
[0128] At the same time, the water guide structure 2 also includes
a second water guide portion 5 communicated with a water outlet end
of the first water guide portion 4. The second water guide portion
5 guides washing water to a water receiving device 6 below the
washing tub 1. Since the washing tub 1 is in a high-speed rotation
state in the dewatering operation, in order to prevent washing
water from flowing back into the washing tub 1 from the water guide
structure 2 in the high-speed rotation state of the washing tub 1,
the distance between the outer wall 201 of the first water guide
portion 4 and the axis of the washing tub 1 is set to show a
gradual change trend in the direction from the top of the washing
tub 1 to the bottom of the washing tub 1, and the distance between
the outer wall 201 of the second water guide portion 5 and the axis
of the washing tub 1 is set to show a gradual change trend in the
direction from the top of the washing tub 1 to the bottom of the
washing tub 1. More preferably, the distance between the first
water guide portion 4 and the axis of the washing tub 1 changes in
a progressive increase trend; the distance between the second water
guide portion 5 and the axis of the washing tub 1 changes in a
progressive decrease trend. The washing tub of the present
disclosure is provided with a multi-section water guide structure 2
exploiting the flowing trend of water in the washing tub 1 rotating
at a high speed, thus avoiding the back flow of the water flow
during draining, and guaranteeing the concentrated draining of the
water flow during draining.
[0129] A section of the water guide structure 2 embedded in the
washing tub 1 is designed as a wall structure, which allows the
water inside the water guide structure 2 to leave the water guide
chamber and enter a larger space inside the water receiving device
6 at the lower part of the washing tub 1 as early as possible, thus
avoiding excessive water inside the water guide structure 2 during
dewatering, resulting in hazards such as increased noise and
vibration. This single wall structure retains the outer side
portion and when water presses against the outer wall 201 under the
action of centrifugal force, the single wall can block the water,
thus reducing the possibility that water splashes out of the water
guide structure 2. An arc shape of the single wall is consistent
with the dewatering direction, which reduces the shearing force and
stressed area applied to the water, thereby reducing the risk of
splashing water. In order to maximize the capacity of the inner
tub, during dewatering, the water is attached to the outer wall of
the water channel under the action of centrifugal force, in order
to guarantee the rapid outflow of the water and reduce the
vibration and noise generated by the accumulated water, the outer
wall of the water channel is in large-arc transition and cannot
have noticeable corner transitions.
