incorporated herein by reference.
FIELD
[0002] The present disclosure relates to a technology field of
washing equipment, and more particularly to a heat pump drying or
washing-drying machine.
BACKGROUND
[0003] In the heat pump drying or washing-drying machine of the
related art, the heat pump system generates much condensed water
when condensing airflows, and the collected condensed water is
drained away by a draining pump, thus resulting in a relatively
complex structure.
SUMMARY
[0004] The present disclosure seeks to solve at least one of
problems existing in the related art to at least some extent. For
this purpose, the present disclosure provides a heat pump drying or
washing-drying machine. A draining structure of a condensed water
of the heat pump drying or washing-drying machine has few parts and
a strong universality.
[0005] The heat pump drying or washing-drying machine according to
embodiments of the present disclosure includes a drum for holding
laundry; a heat pump module including a heat pump mounting box, a
condenser, an evaporator, a fan and a compressor, in which the
condenser and the evaporator are mounted in the heat pump mounting
box, and the heat pump mounting box is provided with a draining
port for draining away a condensed water; and a condensed water
draining duct having an upper end connected with the draining port
and a lower end communicated with the drum, and the condensed water
draining duct extending along a gravity direction from the upper
end to the lower end.
[0006] With the heat pump drying or washing-drying machine
according to embodiments of the present disclosure, the condensed
water generated in the heat pump module can automatically flow to
the drum along the condensed water draining duct under effect of
gravity, such that an additional draining pump doesn't need to be
provided separately when discharging out the condensed water, thus
reducing the number of parts in the heat pump module, improving the
universality of the heat pump module and decreasing the cost of the
heat pump drying or washing-drying machine.
[0007] In some embodiments, the heat pump mounting box includes a
base, the base is provided with an air inlet, an
evaporator-condenser mounting chamber, a fan mounting chamber, a
fan adapting port and an air outlet, the air inlet is communicated
with the evaporator-condenser mounting chamber and the drum
respectively, the air outlet is communicated with the fan mounting
chamber and the drum respectively, and the evaporator-condenser
mounting chamber is communicated with the fan mounting chamber via
the fan adapting port, in which the condenser and the evaporator
are disposed in the evaporator-condenser mounting chamber, and the
fan is disposed in the fan mounting chamber. Thus, the condenser,
the evaporator and the fan can be integrally mounted in the
base.
[0008] Specifically, the base is further provided with a condensed
water gathering chamber communicated with the evaporator-condenser
mounting chamber, and the draining port is formed in a bottom wall
of the condensed water gathering chamber. Thereby, it is convenient
to gather the condensed water in the evaporator-condenser mounting
chamber by providing the condensed water gathering chamber.
[0009] Optionally, the condensed water gathering chamber is
communicated with the evaporator-condenser mounting chamber via the
fan adapting port. Thereby, a flowing direction of the condensed

discharge efficiency of the condensed water is improved.
[0010] Advantageously, the condensed water gathering chamber is
disposed adjacent to the fan mounting chamber, and located under
the evaporator-condenser mounting chamber. Thereby, the arrangement
of each chamber in the base is reasonable and compact, so as to
discharge out water and air conveniently.
[0011] Further, the heat pump mounting box further includes an air
channel guiding plate, the air channel guiding plate is mounted on
the base and defines an air guiding channel with the base, and the
air guiding channel has a channel inlet communicated with the air
inlet and a channel outlet communicated with the
evaporator-condenser mounting chamber. Thereby, before the air
condenses and is heated, the airflow can be introduced into the air
guiding channel to receive a preprocessing so as to improve the
laundry drying performance of the heat pump drying or
washing-drying machine and prevent the condensed water from being
generated in the air guiding channel.
[0012] In some embodiments, the base is provided with a compressor
mounting area, and the compressor is disposed in the compressor
mounting area. Thus, the heat pump module can be assembled into a
modular structure, and when assembling the heat pump drying or

duct is connected to a rear end surface of the drum, so as to avoid
a poor drainage resulted from interference of other parts.

DETAILED DESCRIPTION
[0025] Reference will be made in detail to embodiments of the
present disclosure. The same or similar elements and the elements
having same or similar functions are denoted by like reference
numerals throughout the descriptions. The embodiments described
herein with reference to drawings are explanatory, illustrative,
and used to generally understand the present disclosure. The
embodiments shall not be construed to limit the present
disclosure.
[0026] A heat pump drying or washing-drying machine according to
embodiments of the present disclosure will be described with
reference to FIGS. 1-6 in the following.
[0027] As shown in FIGS. 1 and 2, the heat pump drying or
washing-drying machine according to embodiments of the present
disclosure includes a drum 7 for holding laundry, a heat pump
module and a condensed water draining duct 6.
[0028] The heat pump module includes a heat pump mounting box 1, a
condenser 2, an evaporator 3, a fan 5 and a compressor 4. The
condenser 2 and the evaporator 3 are mounted in the heat pump
mounting box 1, and the heat pump mounting box 1 is provided with a
draining port 104 for draining away a condensed water. An upper end
61 of the condensed water draining duct 6 is connected with the
draining port 104, a lower end 62 of the condensed water draining
duct 6 is connected with the drum 7, and the condensed water
draining duct 6 extends along a gravity direction from the upper
end 61 to the lower end 62.
[0029] Specifically, the compressor 4, the condenser 2 and the
evaporator 3 define a refrigeration cycle path of a refrigerant,
and the fan 5 is used for driving an airflow flowing through
laundry to pass through the evaporator 3 and the condenser 2
successively, and then to flow to the laundry again, so as to form
a circulating air.
[0030] When the heat pump module operates, the compressor 4
compresses the refrigerant therein into a high temperature and high
pressure gas refrigerant, then the high temperature and high
pressure gas refrigerant is pumped into the condenser 2 to release
heat and condense into a low temperature and high pressure
refrigerant, subsequently the refrigerant turns into a low
temperature and low pressure gas-liquid two-phase refrigerant after
flowing through a dryer and throttled by a throttling device, and
then the low temperature and low pressure refrigerant flows into
the evaporator 3 to absorb heat and evaporate into a low
temperature and low pressure gas refrigerant, eventually the
refrigerant in the evaporator 3 returns to the compressor 4 to be
compressed again, and thus a cycle is repeated in such way.
[0031] Due to the condensation and evaporation of the refrigerant
in the condenser 2 and the evaporator 3, the air flowing
therethrough can be heated and cooled. Under the driving of the fan
5, the air can flow circularly between the heat pump module and the
drum 7 to form the circulating air, so as to dry the laundry in the
drum 7 gradually.
[0032] Specifically, when the fan 5 is started, the laundry in the
drum 7 can be flipped ceaselessly, the heat pump module can provide
the drum 7 with a hot and dry air flow, and moisture of the laundry
absorbs heat and evaporates into water vapor under the heating of
the hot and dry air flow. The airflow mingled with the water vapor
flows from the drum 7 into the heat pump module. The wet air in the
heat pump module firstly flows through the evaporator 3. Since the
refrigerant in the refrigeration cycle path absorbs heat in the
evaporator 3, a temperature of the air flowing through the
evaporator 3 in an air circulating path is reduced sharply. After
the air is cooled, the water vapor in the air condenses into fluid
drops or water mist, and the fluid drops or water mist adhered to
the surface of the evaporator 3 can flow downwards along the
evaporator 3 under a gravity effect.
[0033] The humidity of the air after being cooled is reduced, and
then the air flows through the condenser 2. Since the refrigerant
in the refrigeration cycle path releases heat in the condenser 2,
the air flowing through the condenser 2 in the air circulating path
is heated, so that the airflow turns into the hot and dry air and
is blown back to the drum 7 again. The hot and dry air can dry the
laundry in the drum 7 after entering the drum 7. The hot and dry
air absorbs the moisture of the laundry and then turns into a wet
and hot air, and the wet and hot air is blown out again. In such
way, the cycle is repeated. The refrigeration cycle of the
refrigerant cooperates with the air circulation in the device so as
to dry the laundry in the drum 7 quickly.
[0034] In the heat pump mounting box 1, the condensed water gathers
at the draining port 104, so that the condensed water can flow into
the drum 7 through the condensed water draining duct 6, and then
the condensed water can be discharged out from the heat pump drying
or washing-drying machine, along with the water in the drum 7.
[0035] For example, in some embodiments, after entering the drum 7,
the condensed water can be discharged to a draining pump through a
lower portion of the drum, in which the draining pump can discharge
the condensed water out. That is to say, the draining pump of the
whole machine can discharge out the water used for washing the
laundry or the water generated by spin drying, and also can
discharge out the condensed water generated when drying the
laundry, thus achieving the goal of using one pump for a dual
function. An additional draining pump doesn't need to be provided
separately when discharging out the condensed water, so as to
reduce the number of parts in the heat pump module and improve the
universality of the heat pump module.
[0036] In the heat pump drying or washing-drying machine according
to embodiments of the present disclosure, the condensed water
generated in the heat pump module can flow along the condensed
water draining duct 6 to the drum 7 automatically under effect of
gravity, so that the additional draining pump doesn't need to be
provided separately when discharging out the condensed water, thus
reducing the number of the parts in the heat pump module, improving
the universality of the heat pump module and decreasing the cost of
the heat pump drying or washing-drying machine.
[0037] Optionally, the condensed water draining duct 6 is a rubber
duct, and thereby the condensed water draining duct 6 can resist a
relatively big vibration when being used, so as to ensure that the
condensed water draining duct 6 keeps in a good connection with the
draining port 104 and the drum 7.
[0038] Optionally, as shown in FIGS. 1 and 2, the lower end 62 of
the condensed water draining duct 6 is connected with a rear end
surface of the drum 7. Herein, an access 71 is formed in a front
end surface of the drum 7, and a door of the heat pump drying or
washing-drying machine is provided at a front end thereof, in which
the door is used for opening or closing the access 71. The rear end
surface of the drum 7 is located at a back surface of the heat pump
drying or washing-drying machine. Since the lower end 62 of the
condensed water draining duct 6 is connected to the rear end
surface of the drum 7, the condensed water draining duct 6
encounters few interferential parts, so that the condensed water
draining duct 6 can hang down naturally along the gravity
direction.
[0039] In a specific embodiment, the condensed water is exported
from the heat pump module after being condensed by the evaporator
3. Then, the condensed water is conveyed to a hole in the rear of
the drum 7 through the condensed water draining duct 6 configured
as the rubber duct, and further discharged to the draining pump of
the whole machine through the lower portion of the drum. The
draining pump discharges out the condensed water at intervals.
[0040] With a system structural arrangement of the heat pump drying
or washing-drying machine designed based on an integrated top-set
design, the condensed water is led from the heat pump module to the
rear of the drum by the condensed water draining duct 6, and then
discharged out by the draining pump of the whole machine after
flowing through the lower portion of the drum. Gravity is used for
discharging out the condensed water, so that the additional
draining pump for the condensed water is not needed and the
universality of the parts is improved to the greatest extent.
[0041] In some embodiments, as shown in FIGS. 3, 4 and 6, the heat
pump mounting box 1 includes a base 100, and the base 100 is
provided with an air inlet 101, an evaporator-condenser mounting
chamber 110, a fan mounting chamber 120, a fan adapting port 103
and an air outlet 102. The air inlet 101 is communicated with the
evaporator-condenser mounting chamber 110 and the drum 7
respectively, the air outlet 102 is communicated with the fan
mounting chamber 120 and the drum 7 respectively, and the
evaporator-condenser mounting chamber 110 is communicated with the
fan mounting chamber 120 via the fan adapting port 103, in which
the condenser 2 and the evaporator 3 are disposed in the
evaporator-condenser mounting chamber 110, and the fan 5 is
disposed in the fan mounting chamber 120, such that the condenser
2, the evaporator 3 and the fan 5 can be integrally mounted in the
base 100.
[0042] Specifically, as shown in FIG. 3, the evaporator-condenser
mounting chamber 110 includes an evaporator mounting area 111 and a
condenser mounting area 112, the evaporator 3 of the heat pump
module is disposed in the evaporator mounting area 111, and the
condenser 2 of the heat pump module is disposed in the condenser
mounting area 112.
[0043] Under the driving of the fan 5, a wet and cold air in the
drum 7 is sucked into the evaporator-condenser mounting chamber 110
through the air inlet 101. The airflow in the evaporator-condenser
mounting chamber 110 firstly flows through the evaporator 3 for
dehumidification by condensation, and then flows through the
condenser 2 to be heated. The hot and dry air obtained by heating
the airflow is blown to the fan mounting chamber 120 and then to
the drum 7 through the air outlet 102. After entering the drum 7,
the hot and dry air is mixed with the wet and cold air in the drum
7. Then, the wet and cold air in the drum 7 is blown to the base
100 again, and in such way, the circulating air between the base
100 and the drum 7 is formed.
[0044] Specifically, the base 100 is further provided with a
condensed water gathering chamber. The condensed water gathering
chamber is communicated with the evaporator-condenser mounting
chamber 110, the draining port 104 is formed in a bottom wall of
the condensed water gathering chamber, such that the condensed
water in the evaporator-condenser mounting chamber 110 can be
discharged into the condensed water gathering chamber and then
discharged out from the draining port 104. The arrangement of the
condensed water gathering chamber is convenient to gather the
condensed water in the evaporator-condenser mounting chamber 110,
and after providing the condensed water gathering chamber
separately, it is also convenient for the condensed water gathering
chamber to be communicated with other chamber in the base 100, so
that more condensed water can be collected and the condensed water
can be discharged more thoroughly.
[0045] Advantageously, the draining port 104 is located at a lowest
site of the bottom wall of the base 100, so that the condensed
water in the base 100 can flow to the draining port 104
automatically, which is convenient to discharge out the condensed
water completely.
[0046] In some embodiments, the condensed water gathering chamber
is communicated with the evaporator-condenser mounting chamber 110
via the fan adapting port 103, so that the condensed water in the
evaporator-condenser mounting chamber 110 can flow to the condensed
water gathering chamber through the fan adapting port 103 and
further be discharged out therefrom.
[0047] Specifically, as shown in FIGS. 5 and 6, the fan mounting
chamber 120 is located under the evaporator-condenser mounting
chamber 110, an air-out guiding duct 400 is connected to a side
wall of the fan mounting chamber 120, and an opening of the air-out
guiding duct 400 is configured to be the air outlet 102. A
centrifugal wind wheel 51 is mounted in the fan mounting chamber
120. When the fan 5 operates, the airflow in the
evaporator-condenser mounting chamber 110 is blown to the fan
mounting chamber 120 through the fan adapting port 103, and then is
blown to the air-out guiding duct 400 through the side of the fan
mounting chamber 120. That is to say, under effect of the blowing
of the centrifugal wind wheel 51, the airflow in the fan mounting
chamber 120 is inhaled from top and blown out from the horizontal
side.
[0048] Advantageously, since a flowing direction of the air is
configured in such a manner that the airflow in the
evaporator-condenser mounting chamber 110 is blown to the fan
mounting chamber 120 through the fan adapting port 103, and the
condensed water gathering chamber is communicated with the
evaporator-condenser mounting chamber 110 via the fan adapting port
103, a flowing direction of the condensed water is the same with
the flowing direction of the air, and thus the discharge efficiency
of the condensed water is improved.
[0049] Advantageously, the condensed water gathering chamber is
disposed adjacent to the fan mounting chamber 120, and located
under the evaporator-condenser mounting chamber 110. More
specifically, as shown in FIGS. 5 and 6, the fan mounting chamber
120 is located under the condenser mounting area 112, and the
condensed water gathering chamber is located under the evaporator
mounting area 111. In this way, the arrangement of each chamber in
the base 100 is reasonable and compact, so as to discharge out
water and air conveniently.
[0050] In some embodiments, as shown in FIGS. 3 and 4, the heat
pump mounting box 1 further includes an air channel guiding plate
200, and the air channel guiding plate 200 is mounted on the base
100 and defines an air guiding channel 210 with the base 100. The
air guiding channel 210 has a channel inlet 211 and a channel
outlet 212, the channel inlet 211 is communicated with the air
inlet 101, and the channel outlet 212 is communicated with the
evaporator-condenser mounting chamber 110. An outer top wall
surface of the air channel guiding plate 200 is used to
schematically indicate the air guiding channel 210 in FIGS. 3 and
4.
[0051] Thus, the air in the drum 7 enters the air guiding channel
210 through the channel inlet 211 and further enters the
evaporator-condenser mounting chamber 110 through the channel
outlet 212. Before the air condenses and is heated, the airflow may
be introduced into the air guiding channel 210 to receive a
preprocessing, so as to improve the laundry drying performance of
the heat pump drying or washing-drying machine.
[0052] It should be noted that, the air channel guiding plate 200
may be fixed on the base 100 by a fastener such as a screw, or be
connected with the base 100 by a snap, or be hot melted on the base
100.
[0053] Further, as shown in FIG. 4, the heat mounting box 1
includes a soft-flock filtering mesh assembly 300. The soft-flock
filtering mesh assembly 300 is drawably mounted to at least one of
the base 100 and the air channel guiding plate 200, thereby
removing the soft flocks.
[0054] The soft-flock filtering mesh assembly 300 is drawably
mounted to at least one of the base 100 and the air channel guiding
plate 200, which includes following three situations: the
soft-flock filtering mesh assembly 300 is drawably mounted to the
base 100; the soft-flock filtering mesh assembly 300 is drawably
mounted to the air channel guiding plate 200; and the soft-flock
filtering mesh assembly 300 is drawably mounted to the base 100 and
the air channel guiding plate 200.
[0055] Specifically, as shown in FIG. 4, the soft-flock filtering
mesh assembly 300 is disposed at the channel outlet 212, so as to
intercept the soft flocks in the dried air blown to the
evaporator-condenser mounting chamber 110.
[0056] Thus, on one hand, since the air guiding channel 210 is
communicated with the channel inlet 211 and the channel outlet 212
directly, the air flowing out from the drum can entirely enter the
air guiding channel 210 through the air inlet 101, then entirely
enter the evaporator-condenser mounting chamber 110 through the
channel outlet 212 after being intercepted and filtered by the
soft-flock filtering mesh assembly 300, and eventually exchange
heat with the evaporator 3 and the condenser 2 in the
evaporator-condenser mounting chamber 110, thereby avoiding loss of
the dried air and preventing the condensed water from being
gathered in the air guiding channel 210. On the other hand, since
the soft-flock filtering mesh assembly 300 can be separately drawn
out from the at least one of the base 100 and the air channel
guiding plate 200, the soft-flock filtering mesh assembly 300 can
be drawn out to be cleaned easily, thereby avoiding accumulation or
even leakage of the soft flocks.
[0057] From the above, the air channel guiding plate 200 is mounted
on the base 100 and defines the air guiding channel 210 with the
base 100, and the air guiding channel 210 is communicated with the
channel inlet 211 and the channel outlet 212 directly. On the other
hand, the soft-flock filtering mesh assembly 300 is drawably
mounted to the at least one of the base 100 and the air channel
guiding plate 200, such that the heat pump mounting box 1 has a
good connection leakproofness and is easy to be cleaned, and
thereby it is not easy for the air quantity loss and the soft flock
accumulation to come about.
[0058] Further, as shown in FIGS. 3 and 4, the base 100 is further
provided with a compressor mounting area 117, the compressor 4 of
the heat pump module is disposed in the compressor mounting area
117, and other parts of the heat pump module (such as the dryer and
the throttling device) are also mounted in the heat pump mounting
box 1, such that the heat pump module can be assembled into a
modular structure. Thus, when assembling the heat pump drying or
washing-drying machine in a later period, it is very easy to
assemble, detach and maintain the heat pump module.
[0059] In the specification, it is to be understood that terms such
as "central," "longitudinal," "lateral," "length," "width,"
"thickness," "upper," "lower," "front," "rear," "left," "right,"
"vertical," "horizontal," "top," "bottom," "inner," "outer,"
"clockwise," and "counterclockwise" should be construed to refer to
the orientation as then described or as shown in the drawings under
discussion. These relative terms are for convenience of description
and do not require that the present disclosure be constructed or
operated in a particular orientation.
[0060] In addition, terms such as "first" and "second" are used
herein for purposes of description and are not intended to indicate
or imply relative importance or significance or to imply the number
of indicated technical features. Thus, the feature defined with
"first" and "second" may comprise one or more of this feature. In
the description of the present disclosure, "a plurality of" means
two or more than two, unless specified otherwise.
[0061] In the present disclosure, unless specified or limited
otherwise, the terms "mounted," "connected," "coupled," "fixed" and
the like are used broadly, and may be, for example, fixed
connections, detachable connections, or integral connections; may
also be mechanical or electrical connections; may also be direct
connections or indirect connections via intervening structures; may
also be inner communications of two elements, which can be
understood by those skilled in the art according to specific
situations.
[0062] In the present disclosure, unless specified or limited
otherwise, a structure in which a first feature is "on" or "below"
a second feature may include an embodiment in which the first
feature is in direct contact with the second feature, and may also
include an embodiment in which the first feature and the second
feature are not in direct contact with each other, but are
contacted via an additional feature formed therebetween.
Furthermore, a first feature "on," "above," or "on top of" a second
feature may include an embodiment in which the first feature is
right or obliquely "on," "above," or "on top of" the second
feature, or just means that the first feature is at a height higher
than that of the second feature; while a first feature "below,"
"under," or "on bottom of" a second feature may include an
embodiment in which the first feature is right or obliquely
"below," "under," or "on bottom of" the second feature, or just
means that the first feature is at a height lower than that of the
second feature.
[0063] Reference throughout this specification to "an embodiment,"
"some embodiments," "one embodiment", "another example," "an
example," "a specific example," or "some examples," means that a
particular feature, structure, material, or characteristic
described in connection with the embodiment or example is included
in at least one embodiment or example of the present disclosure.
Thus, the appearances of the phrases such as "in some embodiments,"
"in one embodiment", "in an embodiment", "in another example," "in
an example," "in a specific example," or "in some examples," in
various places throughout this specification are not necessarily
referring to the same embodiment or example of the present
disclosure. Furthermore, the particular features, structures,
materials, or characteristics may be combined in any suitable
manner in one or more embodiments or examples.
[0064] Although explanatory embodiments have been shown and
described, it would be appreciated by those skilled in the art that
the above embodiments cannot be construed to limit the present
disclosure, and changes, alternatives, and modifications can be
made in the embodiments without departing from spirit, principles
and scope of the present disclosure.
