Description
TECHNICAL FIELD
[0001] The disclosure relates to the technical field of washing
machines, and in particular relates to an automatic adding system
for adding detergent, degermingagent, softener and the like to a
washing machine, and a washing machine.
BACKGROUND
[0002] An existing washing machine is generally provided with a
detergent (including softener and degerming agent) feeding device
for dissolving detergent and then conveying dissolved detergent
into an outer drum of the washing machine. But before the washing
machine works, a user needs to add the detergent into a detergent
box based on own feelings, so that the detergent is inconvenient to
add, and meanwhile the amount of detergent added is also difficult
to grasp. Along with the improvement on automation of the washing
machine, at present, more and more washing machines are provided
with automatic detergent adding devices.
[0003] In the prior art, an automatic detergent adding device is
provided with a detergent storage box for storing the detergent, a
certain amount of detergent is extracted from the detergent storage
box and added into the outer drum of the washing machine via the
automatic detergent adding device, and then clothes are washed. The
detergent is not dissolved and diluted during an automatic
detergent adding process, so that the detergent is put onto a part
of clothes in a concentrated manner, and the part of the clothes
may fade, while the other clothes may not be in full contact with
the detergent, and thus the clothes cannot be cleaned.
[0004] In order to overcome the abovementioned problem, the
automatic detergent adding device in the prior art is also provided
with a detergent diluting box or a water injection slot component
of a washing machine, and the certain amount of detergent is
extracted from the detergent storage box and added into the
detergent diluting box or the water injection slot component of the
washing machine via the automatic detergent adding device, and
washed into a washing drum by tap water from a water inlet
pipeline. A Chinese patent with an application number of
CN02121057.8 discloses an automatic liquid detergent feeding device
of a washing machine; the device comprises a detergent storage box,
an air press-in part, an exhaust pipe and a discharge pipe, wherein
the detergent storage box is positioned at the upper part of a
washing slot, and liquid detergent in a proper water level as well
as an airtight air layer are stored in the sealed detergent storage
box. The exhaust pipe is arranged between the detergent storage box
and the air press-in part; one end of the discharge pipe is
connected with one side of the detergent storage box while the
other end of the discharge pipe is connected with the washing slot
via a specified path.
[0005] A Chinese patent with an application number of
CN201220574733.2 discloses an automatic liquid detergent feeding
device comprising a water injection box, a drawer box installed in
the water injection box, a detergent temporary storage box
connected with the water injection box, a pump connected with the
detergent temporary storage box, and a liquid detergent conveying
pipeline. The drawer box comprises a detergent storage box
positioned on the inner side of the water injection box and a
distribution box connected with the detergent temporary storage
box, and an opening through which the drawer box can be put in or
taken out is formed in the outer side of the water injection
box.
[0006] It can be known that in the automatic detergent adding
device, the detergent in the detergent diluting box or the water
injection slot component of the washing machine is washed into the
outer drum of the washing machine by inlet water. Although such
structure can achieve automatic adding of the detergent and
dissolve and dilute the detergent, the automatic detergent adding
device is complex in structure and high in cost due to arrangement
of the detergent diluting box or the water injection slot component
of the washing machine. Furthermore, after the washing machine is
used for a long time, the detergent may be coagulated and remain in
the detergent diluting box or the water injection slot component of
the washing machine, which increases the burden of cleaning the
detergent diluting box or the water injection slot component of the
washing machine. Furthermore, through actual application of the
washing machine with the detergent diluting box or the water
injection slot component of the washing machine, it can be found
that during a washing process, the phenomenon that detergent foam
overflows the detergent diluting box or the water injection slot
component of the washing machine may occur due to a sealing
problem, which brings great inconvenience to the user. Furthermore,
by using the abovementioned structure, water flows too fast or
mixing time of the detergent and the tap water is too short, so
that the detergent cannot be fully mixed with the water, and thus
the washing efficiency is not high, the clothes are not thoroughly
cleaned, and the clothes may fade and fibers of the clothes may
even be damaged in washing.
[0007] Therefore, the present disclosure is provided.
SUMMARY
[0008] The technical problem to be solved by the disclosure is to
provide an automatic detergent adding system to overcome defects of
the prior art, solve the problems that an existing automatic
detergent adding device is complex in structure and high in cost,
and meanwhile overcome the problems that the clothes are damaged
and insufficiently washed due to the fact that the detergent is not
fully dissolved before entering the outer drum of the washing
machine.
[0009] In order to solve the abovementioned technical problems, the
technical scheme of the present disclosure has a basic concept as
follows:
[0010] an automatic detergent adding system, comprises a detergent
container containing detergent, and an automatic detergent feeding
device connected with the detergent container, wherein the
automatic detergent feeding device communicates with a pipe joint
of a water inlet pipeline of a washing machine, and the pipe joint
communicates with a water conduit connected with an outer drum. The
detergent in the automatic detergent feeding device and the tap
water from the water inlet pipeline are converged and flow to the
outer drum via the water conduit, and a water injection slot
component of a washing machine in the prior art is omitted, so that
the detergent enters a washing drum after being fully dissolved,
and thus the washing efficiency is improved.
[0011] The automatic detergent feeding device comprises a conveying
pipe communicating with the pipe joint, a draw-off pump of which
one end is connected with the conveying pipe, another end is
connected with the detergent container, and a control device
separately connected with a washing machine controller and the
draw-off pump.
[0012] The automatic detergent feeding device is provided with the
conveying pipe connected with the pipe joint, wherein the pipe
joint is a bowl-shaped or hollow hemispherical structure, an
opening end of the pipe joint is connected with the water conduit,
a conveying opening is formed in the pipe joint, the conveying pipe
communicates with the pipe joint via the conveying opening, the
pipe joint is also provided with a water inlet, the water inlet
pipeline communicates with the pipe joint via the water inlet, and
the conveying opening is deviated from a water flow direction in
the water inlet.
[0013] A pipe body of the connected part of the conveying pipe for
connecting with the pipe joint is an elbow pipe, and the elbow of
the elbow pipe is arranged to face the conveying opening.
[0014] The water inlet is located at one end of the pipe joint away
from the water conduit, and the conveying opening is located at a
middle of the pipe joint or at one end of the pipe joint close to
the water conduit.
[0015] The water inlet comprises a first water inlet and a second
water inlet, and the first water inlet and the second water inlet
are symmetrically arranged with respect to an axis of the pipe
joint. Since the pipe joint is of the bowl-shaped structure, the
water inlet will have a certain degree of inclination, so that
opposite collision of inlet water flows is formed at a middle of
the pipe joint. Preferably, the water inlet is positioned on the
side of the pipe joint away from the water conduit, and the
conveying opening is positioned at a middle of the pipe joint, the
detergent is mixed with the tap water at the opposite collision
part of the water flows to be dissolved preliminarily, and thus the
mixing efficiency of the detergent and the tap water can be further
improved.
[0016] The water conduit is provided with a detergent dissolving
structure, the detergent dissolving structure is a flowing-around
structure and/or a structure for prolonging the flow time of fluid.
When a mixture of the detergent and the tap water passes through
the water conduit, the detergent is fully dissolved, so that the
washing efficiency is improved, and the damage to the clothes can
be avoided.
[0017] The flowing-around structure is a plurality of
protrusions/grooves distributed on an inner wall of the pipe body
along a length direction of the pipe body, preferably, the water
conduit is a corrugated pipe. Therefore, the washing efficiency can
be improved, and when the washing machine vibrates, influence on
the pipeline is also reduced by using mechanical property of the
corrugated pipe.
[0018] In the water conduit, the structure for prolonging the flow
time of the fluid is a spiral pipe or other bent pipe. Since such
arrangement, the flow time of the tap water and the detergent in
the water conduit is prolonged, and the detergent is also better
dissolved in the water.
[0019] After using the technical scheme, compared with the prior
art, the present disclosure has the beneficial effects as
follows:
[0020] the present disclosure provides an automatic detergent
adding system by improving an existing automatic detergent adding
device of washing machine. The water inlet pipeline is connected
with the detergent conveying pipe via the water conduit, the
detergent and the tap water are guided into the outer drum via the
water conduit connected with the outer drum for washing. So that a
water injection slot component in an original washing machine is
omitted. The structure is simple, and a series of problems caused
by existence of the water injection slot component are also
avoided. The water and the detergent are preliminarily mixed in the
pipe joint before flowing into the water conduit, and the washing
efficiency is improved. In order to further mix the detergent with
the water, the present disclosure improves positions of the water
inlet of the water inlet pipeline and the conveying opening of the
conveying pipe, and the water conduit is set to be the special
structure, namely the flowing-around structure or the structure for
prolonging the flow time of the tap water and the detergent. So
that the detergent is fully dissolved, the manufacturing cost is
reduced, mixing of the detergent and the water is accelerated, the
clothes washing efficiency is improved, and the problems that the
clothes fade and fibers of the clothes are damaged due to over high
concentration of the detergent are avoided.
[0021] The disclosure also provides a washing machine having the
automatic detergent adding system, and the washing machine has the
beneficial effects which is the same as the abovementioned
beneficial effects.
[0022] In the following, the present disclosure is further
specifically described through combining with the drawings.

DETAILED DESCRIPTION
[0026] In order to achieve the clearer objects, technical schemes
and advantages of the embodiments of the present disclosure, the
technical schemes in the embodiments will be clearly and completely
described with reference to the drawings in the embodiments of the
present disclosure; the embodiments are used for illustrating the
present disclosure and should not be construed to limit the scope
of the present disclosure.
[0027] As shown in FIG. 1, an automatic detergent adding system
provided by the present disclosure comprises a detergent container
1, and an automatic feeding device 2 connected with the detergent
container 1. The automatic feeding device 2 is connected with a
pipe joint 4 of a water inlet pipeline 3, the pipe joint 4 is
connected with an outer drum of a washing machine via a water
conduit 5. The tap water and detergent flow into a washing drum for
washing after being fully mixed via the pipe joint 4 and the water
conduit 5. When clothes are washed, the automatic detergent feeding
device 2 automatically extracts a certain amount of detergent from
the detergent container 1 according to the condition of the clothes
to be washed, and feeds the detergent into the pipe joint 4 of the
water inlet pipeline 3. Water is fed into the water inlet pipeline
3 via water inlet valves of a washing machine, and the tap water is
converged with the detergent while flowing through the pipe joint
4, and continuously flows through the water conduit 5. During such
a process, the water is mixed with the detergent, the detergent is
dissolved and diluted, and finally, the water and the detergent are
converged and flow into the outer drum of the washing machine along
the water conduit 5. In the automatic detergent adding system, the
detergent is dissolved and diluted by inlet water in the water
conduit 5, and flows into the outer drum of the washing machine. So
that a detergent diluting box or a water injection slot component
of a washing machine is omitted, and thus the structure is
simplified, and the cost is reduced. Meanwhile, the detergent is
dissolved and diluted by water in the water conduit 5, and then
flows into the outer drum of the washing machine. So that the
detergent is uniformly distributed on the clothes and the
utilization rate of the detergent is improved. The problem in the
prior art that the detergent is put onto a certain part of clothes
in a concentrated manner causing damage to the clothes or the
clothes may not be in full contact with the detergent causing the
clothes not to be washed is solved, and the washing efficiency is
ensured.
Embodiment 1
[0028] As shown in FIG. 1, an automatic feeding device 2 provided
by the embodiment comprises a conveying pipe 6 communicating with a
water conduit 5, a draw-off pump 7 of which one end is connected
with the conveying pipe 6 and the other end is connected with the
detergent container, wherein the automatic feeding device 2 may be
provided with the other detergent extraction device instead of the
draw-off pump. For example, a device for extracting the detergent
by using the action of hydraulic pressure, or a device for
extracting the detergent by using a Venturi principle. The
detergent is added in a pumping manner due to the fact that the
draw-off pump is adjustable in lift, and the conveying capacity and
the conveying efficiency can be ensured. The automatic feeding
device 2 is also provided with a control device (not shown in
figures) separately connected with a washing machine controller and
the draw-off pump 7, which is used for adding different kinds of
detergents during different washing processes. For example, the
detergent is added when washing, and the softener is added when
rinsing. The adding amount and adding time of the detergent are
automatically adjusted by the washing machine controller, and thus
automatic adding of the detergent is achieved.
[0029] As shown in FIG. 2 and FIG. 3, as a further preferred
embodiment of the present disclosure, a pipe joint 4 is of a
bowl-shaped or hollow hemispherical structure; such arrangement is
used for ensuring that the direction of a water flow has a certain
gradient when the water flow enters the pipe joint 4; the pipe
joint 4 certainly can also be set to be a pipe body in other
shapes, such as a columnar cavity, and the purpose that the inlet
water flow enters the pipe joint 4 with a certain gradient can also
be achieved by adjusting the direction of the water inlet pipeline.
An opening end of the pipe joint 4 and a water conduit 5 are
connected via a fixing clamp, and a sealing piece is arranged; and
the pipe joint 4 and the water conduit 5 certainly can also be
integrally connected to achieve better sealing effect.
[0030] As shown in FIG. 2 and FIG. 3, as a further preferred
embodiment of the present disclosure, a conveying opening 8 at the
connected part of the conveying pipe 6 and the pipe joint 4 and a
water inlet 9 at the connected part of the water inlet pipeline 3
and the pipe joint 4 are not oppositely arranged with respect to
the axis of the pipe joint 4. That is to say, the conveying opening
is deviated from a water flow direction in the water inlet, a
liquid inlet direction of the conveying opening 8 is not in a
straight line with the water flow direction in the water inlet 9.
As most detergent is relatively thick and has poorer flowability
compared with water, such arrangement is used for preventing the
water flow from entering the conveying pipe 6 or preventing the
detergent in the conveying opening 8 from flowing out due to
opposite arrangement of the conveying opening 8 and the water inlet
9.
[0031] As shown in FIG. 1, as a further preferred embodiment of the
present disclosure, a pipe body of the connected part of the
conveying pipe 6 for connecting with the pipe joint 4 is an elbow
pipe, and the elbow is arranged to face the conveying opening 8.
Preferably, the elbow is bent for 90 degrees, so that the water
flow is not prone to be directly washed into the conveying pipe,
and meanwhile the conveying efficiency can be ensured.
[0032] As shown in FIG. 2 and FIG. 3, in order to accelerate full
dissolving of the detergent in the tap water, the water inlet
pipeline is provided with multiple water inlets 9, preferably
having two water inlets 9, namely a first water inlet 91 and a
second water inlet 92 which are symmetrically arranged with respect
to the axis of the pipe joint 4. And the pipe wall of the pipe
joint 4 is arc-shaped, the water flows entering from the two water
inlets are converged in the pipe joint 4, and opposite collision of
the water flows is formed, so that dissolving of the detergent in
the tap water is accelerated. Preferably, the water inlet 9 is
positioned on the side, far away from the water conduit 5, of the
pipe joint 4, and the conveying opening 8 is positioned at a middle
of the pipe joint 4 or at the part, close to the water conduit 5,
of the pipe joint 4, so that the detergent conveyed by the
conveying opening 8 is converged with the tap water in opposite
collision of the water flows and preliminarily mixed with the tap
water.
Embodiment 2
[0033] As shown in FIG. 2 and FIG. 3, as a further preferred
embodiment of the present disclosure, a water conduit 5 is provided
with a detergent dissolving structure 10 for accelerating mixing of
the detergent and the tap water, and the detergent dissolving
structure 10 is a flowing-around structure. According to the above
description of the automatic detergent adding system provided by
the present disclosure, it can be known that the inlet water flows
through the water conduit 5 to be mixed with the detergent and
flows into the outer drum of the washing machine. Due to the fast
flow speed of the inlet water, part of detergent may flow into the
outer drum of the washing machine along with the inlet water
without being fully dissolved and diluted. So that the detergent
dissolving structure 10 is arranged in the water conduit 5 which is
positioned between the detergent conveying opening 8 and the outer
drum of the washing machine, for reducing the flow speed of the
inlet water or allowing the water to flow around, and prolonging
the mixing time of the water flow passing through the water conduit
5 and the detergent, and thus the detergent is fully dissolved and
diluted.
[0034] Preferably, the detergent dissolving structure 10 is a
plurality of protrusions/grooves distributed on the inner wall of
the pipe body along the length direction of the pipe body. The
mixture of the water and the detergent flows through the
protrusions/grooves, so that on the one hand, the flow speed of the
water flow is reduced under the action of the protrusions/grooves,
and on the other hand, the detergent is fully dissolved and diluted
during such a process.
[0035] More preferably, the water conduit 5 is a corrugated pipe
which also plays a role in allowing the flows to flow around. So
that the detergent flows into the outer drum of the washing machine
after being fully dissolved and diluted, and influence on the
pipeline produced by vibration of the washing machine can also be
reduced by using the mechanical property of the corrugated
pipe.
Embodiment 3
[0036] The only difference between the embodiment and the
embodiment 2 is that the detergent dissolving structure 10 of the
water conduit 5 is a spiral pipe or other bent pipe structure. Such
arrangement is used for prolonging the flow time of the tap water
and the detergent in the water conduit 5 and enabling the detergent
to be better dissolved in water. The flowing-around structure
composed of the plurality of protrusions or grooves certainly can
also be arranged in the spiral pipe or the bent pipe for enabling
the detergent to be better fully dissolved in the tap water. So
that the washing efficiency of the washing machine is improved, and
the situation that the detergent is not fully dissolved and thus
the clothes are damaged is avoided.
Embodiment 4
[0037] As show in FIG. 1, on the basis of the abovementioned
embodiments, as a further preferred embodiment of the present
disclosure, an automatic detergent adding system can be provided
with a plurality of detergent containers 1 and a conveying pipe 6,
and a plurality of conveying openings 8 are correspondingly
arranged on the pipe joint 4. When the clothes are washed, the user
often also needs to add the degerming agent to degerm the clothes
or add the softener to soften the clothes according to needs on the
basis of adding the detergent. In order to meet the needs, as shown
in FIG. 1, an automatic detergent adding system provided by the
present disclosure is provided with a plurality of automatic
detergent feeding devices 2, a plurality of detergent conveying
openings 8 and a plurality of detergent containers 1.
[0038] Among them, one automatic detergent feeding device
corresponds to one detergent conveying opening, and also
corresponds to one detergent container at the same time, which
satisfies the needs of users to add detergents, degerming agents or
softeners and realizes the independent automatic feeding of
different kinds of detergent, the degerming agent and the softener,
which is to prevent the detergents or the disinfectants or the
softeners from being mixed with each other and to ensure that the
detergents exert their respective effects.
[0039] As shown in FIG. 1, when the clothes are washed, proper
water temperatures are selected according to different clothes
conditions for improving washing effect of the clothes. The water
inlet pipeline 3 of present disclosure is provided with a cold
water pipeline and a hot water pipeline of which water-out is
controlled by water inlet valves. When the clothes are washed,
different water inlet valves of the washing machine control inlet
water with different temperatures, the inlet water enters the water
conduit 5 via the water inlet 9, inlet water with the needed proper
temperature is formed by mixing, and flows into the outer drum of
the washing machine via the water conduit 5 for washing the
clothes, so that the washing efficiency is improved.
[0040] The specific working process of the present disclosure is
described below with reference to the abovementioned
embodiments.
[0041] When the user needs to wash clothes, the washing machine
controller open the water inlet valve of the cold water pipeline
and the water inlet valve of the hot water pipe at first. The water
temperature is adjusted according to the washing needs, then the
automatic detergent feeding device 2 is switched on, the control
device controls the draw-off pump 7 to extract the detergent from
the detergent container 1 via the conveying pipe 6 for adding the
detergent, and the control device can select the dosage of the
detergent, and select the detergent according to different washing
processes, for example, the detergent is added during the washing
process, and the softener is added during the rinsing process. The
water inlet pipeline 3 is provided with two water inlet pipelines
which are symmetrical with respect to the axis of the pipe joint 4,
and thus a dual-water inlet structure composed of the first water
inlet 91 and the second water inlet 92 is formed. As the pipe joint
4 is of the bowl-shaped or hollow hemispherical structure, the tap
water has a certain gradient while flowing through the pipe joint 4
from the water inlet 9, so that opposite collision of the water
flows is formed in the pipe joint 4. When the detergent enters into
the pipe joint 4 via the conveying pipe 6 and the conveying opening
8, the detergent is preliminarily mixed with the tap water under
the opposite collision of the water flows. And then the mixture of
the tap water and the detergent enters into the water conduit 5. As
the water conduit 5 is provided with the detergent dissolving
structure 10, namely the flowing-around structure and/or the
structure for prolonging the flow time of the tap water, the
detergent and the tap water are fully mixed again in the water
conduit 5, and finally flow into the outer drum of the washing
