Description
TECHNICAL FIELD
[0001] The present disclosure belongs to the field of washing, in
particular to a washing equipment and a water outlet method of
washing water.
BACKGROUND
[0002] A traditional fully-automatic impeller-type washing machine
generally includes an inner drum, an outer drum, a damping part and
a power system. During clothes washing and dehydrating, the inner
drum rotates relative to the outer drum, such that clothes interact
with washing water, to achieve the purpose of washing clothes or
dehydrating, wherein the outer drum is installed outside the inner
drum, to provide support for the inner drum. The outer drum serves
as a water accommodating bucket, a side wall of the inner drum is
uniformly distributed with drainage holes, such that the inner drum
and the outer drum are communicated. In the clothes washing
process, clothes are placed in the inner drum, the water levels of
the two drums are the same, and however, the outer drum is not in
contact with clothes. A volume of the outer drum of the existing
washing machine is larger than a volume of the inner drum, causing
accumulation of more washing water between the inner drum and the
outer drum, the detergent between two drums cannot be sufficiently
utilized, thereby not only increasing water amount during clothes
washing, but also lowering concentration of the detergent during
washing, and causing a rather big volume of the whole washing
machine. In addition, after the washing machine is used for a
period of time, the inner wall of the outer drum and the outer wall
of the inner drum may be adhered with dirt, and may be even moldy,
further the washed clothes may be polluted, and the drum wall is
difficult to clean.
[0003] Aiming at this condition, some manufacturers made some
improvements. To save water resources, more and more washing
machines adopt an inner drum without holes, such that the inner
drum is separated from the outer drum, only the inner drum stores
water, and the outer drum has no water. Drain holes are formed
close to an upper end of the side wall of the inner drum, in this
way, when the washing machine dehydrates, water is splashed on an
inner wall of the inner drum due to the effect of a centrifugal
force, moves upwards along the inner wall of the inner drum, and is
discharged from the drainage holes at the upper end of the inner
drum, thereby improving the effect of water conservation of the
washing machine, and saving use amount of detergent.
[0004] However, the above solution has the following problems:
since the washing machine rotates at a high speed during
dehydration, water in the clothes is thrown away through drain
holes on the side wall of the inner drum, and hits directly on a
side wall of an outer drum, and water easily splashes everywhere,
and water accumulated on the inner wall of the outer drum is easy
to breed bacteria and is not beneficial for environmental
protection.
[0005] A Chinese patent with the application number of CN99230455.5
discloses a single-bucket type water-saving washing machine, a
bucket mouth of the wash bucket is provided with a water collecting
device, the water collecting outlet of the water collecting device
surrounds the bucket mouth along the wash bucket, a water
collecting chamber, arranged at the bucket mouth, of the water
collecting device is connected with a plurality of drainage pipes,
the drainage pipes are arranged symmetrically from top to bottom
along the outer wall of the wash bucket. During spin-drying, the
water collecting device collects centrifugal water flow due to
high-speed rotation, and guides the water flow downwards to
discharge the water flow. Although an outer drum is omitted in the
structure, when the washing machine dehydrates, since washing water
firstly enters the water collecting device, the water collecting
device is an annular structure, washing water filled inside is
discharged downwards at different speeds, thereby destroying the
balance of high-speed rotation of the wash bucket; in addition,
after entering the water collecting device, washing water is guided
to the lower part of the wash bucket, and is collected towards the
center and is discharged, which is not beneficial for water
discharge, such that water is concentrated in the water collecting
chamber under the effect of a centrifugal force and is difficult to
discharge, thereby causing concentration of washing water at the
upper end of the wash bucket, increasing the weight of the upper
part of the wash bucket, and further destroying balance, especially
when much water remains in the wash bucket, most of washing water
is concentrated in the water collecting chamber and cannot be
discharged, thereby improving total center of gravity of the wash
bucket and the outer drum, generating great vibration noise, and
also increasing the working load of a dehydrating motor, and easily
damaging an electrical motor.
[0006] In view of this, the present disclosure is hereby
proposed.

is to overcome shortcomings of the prior art, and provide a washing
equipment which can relatively increase capacity of the wash
barrel, avoid washing water from concentrating above the wash
barrel during dehydration and improve water outlet efficiency.
[0008] In order to solve the above technical problem, a basic
conception of the technical solution adopted in the present
disclosure is as follows: a washing equipment includes a wash
barrel and a water outlet guide assembly.
[0009] The wash barrel is configured to be rotatable, wherein an
inside of the wash barrel is configured to hold water, and an upper
part of a barrel wall of the wash barrel is provided with a water
outlet.
[0010] The water outlet guide assembly is arranged on the barrel
wall and communicated with the water outlet.
[0011] Washing water inside the wash barrel is thrown away through
the water outlet at the upper part and enters the water outlet
guide assembly, and the water outlet guide assembly guides water
downwards to be discharged.
[0012] Further, the washing equipment further includes a water
retaining part, wherein the water retaining part is arranged above
the water outlet to keep water from flowing upwards.
[0013] Further, the water retaining part is constituted by a lower
edge of a balancing ring, or
[0014] the water retaining part is constituted by a structure
formed by an upper opening of the washing barrel being reduced in
diameter; or
[0015] the water retaining part is constituted by an annular convex
rib installed on an inner wall of the wash barrel.
[0016] The above structure improves a speed at which washing water
is discharged outwards through the water outlet, and the water
retaining part plays a role of guiding washing water to reverse and
to be discharged through the water outlet.
[0017] Further, the water outlet guide assembly is provided with a
water guide chamber from top to bottom. An upper part of the water
guide chamber is communicated with the water outlet. A radial width
of the water guide chamber is gradually increased from top to
bottom.
[0018] Further, the water outlet guide assembly is provided with a
water guide chamber from top to bottom, an upper part of the water
guide chamber is communicated with the water outlet. A side wall,
far away from the wash barrel, of the water guide chamber is
inclined from top to bottom to the direction far away from the wash
barrel.
[0019] Preferably, a set inclined angle is 0.degree. to
10.degree.,
[0020] More preferably, the set inclined angle is 1.degree. to
3.degree..
[0021] The above structure is beneficial for the speed at which
washing water is discharged downwards, thereby preventing that
under the effect of the centrifugal force, washing water in the
water guide chamber does not flow downwards and even is clustered
upwards near the water outlet in a reverse direction.
[0022] Further, the water outlet guide assembly comprises an outer
housing; the outer housing is installed on an outside of the barrel
wall corresponding to a position of the water outlet. A certain gap
is formed between the outer housing and the barrel wall to form the
water guide chamber which guides water downwards. The water outlet
on the barrel wall constitutes a water inlet of the water guide
chamber, and a drainage outlet is arranged at a bottom of the water
guide chamber.
[0023] Or, the water outlet guide assembly comprises a housing, the
housing is installed on an outside of the barrel wall. The housing
is internally provided with a water guide chamber which guides
water downwards, a water inlet is arranged, corresponding to the
water outlet on the side, adjacent to the wash barrel, of the
housing. The water guide chamber is communicated with the water
outlet via the water inlet, and a drainage outlet is arranged at a
bottom of the water guide chamber.
[0024] Or, the wash barrel has a double barrel wall which comprises
an inner barrel wall and an outer barrel wall. An upper end of the
double barrel wall is sealed, a bottom of the double barrel wall is
provided with an opening, an upper part of the inner barrel wall is
provided with the water outlet. A gap between the inner barrel wall
and the outer barrel wall constitutes a water guide chamber of the
water outlet guide assembly.
[0025] Or, the water outlet guide assembly comprises a water guide
chamber manufactured by the barrel wall via a bending compression
process, the water guide chamber is hollow. An upper end of a side,
corresponding to the wash barrel, of the water guide chamber is
provided with a water inlet, and a bottom of the water guide
chamber is provided with a drainage outlet.
[0026] Further, an orientation of the water outlet is set along a
radial direction of the wash barrel.
[0027] The structure is beneficial for the discharge of washing
water, and the speed at which washing water is thrown away can be
increased compared with the structure in which water is discharged
upwards from the inside of the wash barrel.
[0028] Further, a water outlet mechanism which is capable of being
opened or closed is arranged at the barrel wall below the water
outlet and/or a barrel bottom of the wash barrel. The water outlet
mechanism is in a close state in the washing process.
[0029] Via the structure, part of washing water inside the wash
barrel can be discharged firstly, and then another part of washing
water in clothes is discharged through the water outlet by
utilizing the centrifugal force of rotation of the wash barrel,
thereby accelerating speed of water drainage and dehydration.
[0030] Further, a part, below the water outlet, of the wash barrel
and the barrel bottom are both set to be waterproof.
[0031] Further, an inner surface of the barrel wall is gradually
arranged in an inclined manner towards the direction far away from
a central axis of the wash barrel from bottom to top.
[0032] Preferably, a set inclined angle is 0.degree. to
15.degree.,
[0033] More preferably, the set inclined angle is 1.degree. to
10.degree..
[0034] The structure improves the speed at which the water inside
the wash barrel climbs upwards along the barrel wall.
[0035] Further, an upper part of the water outlet guide assembly is
directly communicated with the water outlet, and a lower part is
below a horizontal surface on which a barrel bottom is located.
[0036] Preferably, a water discharge direction of a drainage outlet
below the water outlet guide assembly is set downwards or set
downwards in an inclined manner towards the direction far away from
a central axis of the wash barrel.
[0037] The above structure is beneficial for washing water to be
discharged from the lower part of the water guide part, thereby
avoiding accumulation of washing water in the water outlet guide
assembly, which may lead to generation of a larger vibration noise
due to center of gravity of the wash barrel and output load which
drives the wash barrel to rotate.
[0038] Further, the water outlet guide assembly is internally
provided with a reversing water guide structure, to guide water
which is thrown away radially through the water outlet to be
discharged downwards after changing direction.
[0039] Preferably, the reversing water guide structure is provided
with at least one downward inclined surface or an arc surface set
corresponding to the water outlet.
[0040] The above structure can play a role of guiding washing water
to reverse stably, thereby preventing washing water from generating
reflection and splashing inside the water outlet guide assembly,
and avoiding an influence on the speed at which the water outlet
guide assembly guides water downwards.
[0041] Further, the washing equipment further includes a water
collecting part being installed below the wash barrel and
configured to collect water discharged from the wash barrel. The
wash barrel is configured to be rotatably relative to the water
collecting part. The water collecting part comprises a bottom wall
and a water collecting groove, a lower end of the water outlet
guide assembly extends inside the water collecting groove. The
water collecting groove is further provided with a drainage
mechanism which discharges water inside the water collecting
groove.
[0042] Further, the water collecting part further includes a side
wall which is arranged in a circle above the bottom wall, and the
bottom wall and the side wall are sealed to form the water
collecting groove.
[0043] Further, a lowest height of the side wall is set to keep
water in the water collecting groove not overflowing t when the
wash barrel rotates to discharge water.
[0044] Preferably, an upper end of the side wall is not higher than
1/3 of a height of the wash barrel from bottom to top.
[0045] More preferably, the upper end of the side wall is not
higher than 1/5 of the height of the wash barrel from bottom to
top.
[0046] The above structure can avoid a phenomenon of beating the
drum caused by eccentricity of the upper part when the wash barrel
rotates at a high speed, thereby relatively increasing the volume
of the wash barrel.
[0047] Further, the water collecting part is a bucket body
structure, the bottom wall is a bucket bottom, and the side wall is
a peripheral wall. The water collecting part is connected with a
box body of the washing equipment via a damping part.
[0048] Preferably, the bucket bottom is provided with an annular
groove, the lower end of the water outlet guide assembly extends
inside the annular groove, and a drainage outlet is arranged at the
lowest part of the annular groove.
[0049] The above structure can prevent water splashing when washing
water is guided out, thereby being beneficial for rapid discharge
of washing water from the water collecting part.
[0050] Or, the water collecting groove is an annular groove
arranged at the bottom wall.
[0051] Further, at least two water outlet guide assemblies are
arranged, and all the water outlet guide assemblies are
independently uniformly distributed on the barrel wall along a
circumference of the wash barrel.
[0052] The present disclosure further provides a water outlet
method of washing water which can improve water outlet efficiency.
In a rotating process of a wash barrel, internal washing water
rises along an inner wall of the wash barrel and reaches the
outside of the wash barrel through an water outlet at an upper part
of the wash barrel, and is directly guided downwards to discharge
through a water outlet guide assembly arranged on the wash
barrel
[0053] The washing equipment in the present disclosure is an
impeller-type washing machine, or a drum machine, or an all-in-one
washing and drying machine, or a dish washing machine or other
devices which need to discharge washing water via a centrifugal
force.
[0054] After the above technical solution is adopted, the present
disclosure has the following beneficial effects compared with the
prior art.
[0055] The wash barrel of the washing equipment in the present
disclosure can be directly taken as a water holding bucket, can
improve utilization rate of washing water, reduce the use amount of
washing water, and relatively reduce amount of detergent.
Meanwhile, the structure of the upper part of the wash barrel
surrounded by the outer drum is omitted, and the size of the wash
barrel can be set larger, such that the amount of clothes can be
correspondingly increased, thereby realizing the aim of expanding
capacity of the washing equipment. On the other hand, the water
outlet guide assembly is directly communicated with the inside of
the wash barrel, washing water inside the wash barrel is directly
guided downwards, thereby improving water outlet efficiency,
avoiding washing water from concentrating at the upper end of the
wash barrel which may influence rotary balance of the wash barrel,
such that the rotation of the wash barrel is more stable, the noise
is lower during operation, and the service life is longer.
