[0001] The present invention relates to a laundry washing and drying machine that comprises
a condenser.
[0002] In laundry washing and drying machines, air-cooled condensers are widely used, which
realize the condensation process by using the outer environment air in the drying
process after washing. Humid air that comes from over the laundry and passes through
the processing air duct is condensed in the condenser cooled by means of the outer
environment air, thus the air that is dried by being dehumidified is sent again onto
the laundry through the processing air duct. During the drying process, fibers and
lints are formed as the result of laundry rubbing against each other or the drum and
these leave the tub together with the drying air. The lints that form at the end of
the drying cycle accumulate at various places of the condenser and the processing
air pipe. The fibers and lints accumulate particularly at the tub outlet of the processing
air pipe and the elbow portion of the condenser inlet and on the inner surfaces of
the air channels inside the condenser. Water spraying devices are used for cleaning
the fibers and lints however more than one water spraying device is required for cleaning
the fibers and lints accumulating at more than one point thereby increasing costs
and water consumption.
[0003] In the state of the art European Patent Application No.
EP2169107, a spraying device is described, providing the condenser disposed in a dryer to be
washed and thus cleaned of fiber and lint at the end of the drying process.
[0004] The aim of the present invention is the realization of a laundry washing and drying
machine wherein the fibers and lints accumulating in the channels inside the condenser
and the air ducts are provided to be cleaned.
[0005] The laundry washing and drying machine realized in order to attain the aim of the
present invention, explicated in the first claim and the respective claims thereof,
comprises an air duct wherein the processing air circulation in the drying process
is performed, providing the laundry to be dried after the washing process, a condenser
disposed on the air duct, having channels that extend in the flow direction of the
processing air and a spraying device which is disposed at the condenser outlet wherefrom
the processing air leaves the condenser so as to be opposite the channels and which
provides the fibers and lints accumulating in the channels to be washed after the
drying process. The condenser is disposed in an inclined manner at the upper side
of the tub such that the level of the condenser inlet through which the processing
air enters is above the level of the condenser outlet through which the processing
air leaves.
[0006] The condenser channels extends in an inclined manner in the flow direction of the
processing air from the condenser inlet towards the condenser outlet and the water
condensed inside the channels during the drying process leaves the condenser by flowing
downhill. The water delivered into the channels from the spraying device after the
drying process moves in the channels by flowing uphill, partially returning back due
to inclination of the channels, flows downhill and leaves the condenser.
[0007] In an embodiment of the present invention, the condenser comprises a planar ceiling
forming the upper surface of each channel and a planar base forming the lower surface
of the channel and the spraying device comprises spraying nozzles called "flat nozzles"
that deliver water between the ceiling and the base by forming a flat water beam.
The spraying nozzles deliver water into the condenser with the same inclination as
the channels or with a different inclination than the channels so that water impacts
the ceiling of the channels.
[0008] In another embodiment of the present invention, the portions of the air duct, wherein
processing air is conveyed, extending to the condenser inlet and condenser outlet
above the tub is inclined in the same direction as the condenser and hence the channels.
[0009] In another embodiment of the present invention, bends are situated on the air duct
at the sides of the condenser inlet and the tub outlet, and the spraying device is
provided to spray water with enough pressure to reach the bend sections after traversing
the condenser channels.
[0010] In another embodiment of the present invention, the laundry washing and drying machine
comprises a reservoir disposed on the air duct wherein the condensate water draining
from the condenser and the water delivered to the condenser from the spraying device
which partially returns due to inclination is collected and a discharge line providing
the water in the reservoir to be discharged.
[0011] In the laundry washing and drying machine of the present invention, a gain in terms
of space is obtained by disposing the condenser in an inclined manner at the upper
side of the tub, furthermore the water condensed in the channels and the water delivered
from the spraying device are provided to drain from the channels downhill since the
condenser and hence the channels therein are inclined, the condensation efficiency
of the condenser is increased, the fibers and lints accumulating in the condenser
channels and especially in the bend portions are cleaned effectively by a single spraying
device and by consuming a small amount of water.

[0014] The laundry washing and drying machine (1) comprises a body, a drum (2) wherein laundry
is placed, rotating around the horizontal axis, a cylindrical tub (3) wherein the
drum (2) moves, an air duct (4) wherein circulation of the processing air (PA) providing
the drying of the laundry in the drying process after the washing process is performed,
a fan (5) that provides the processing air (PA) to move in the air duct (4), a condenser
(7) disposed above the air duct (4), having at least one channel (6) wherein the processing
air (PA) passing therethrough is condensed, a tub outlet (8) wherefrom the air duct
(4) is connected to the tub (3), providing the processing air (PA) to be delivered
from the tub (3) to the condenser (7), a condenser inlet (9) and a condenser outlet
(10) wherefrom the air duct (4) is connected to the condenser (7) and a spraying device
(11) connected to the water mains, disposed at the condenser outlet (10) opposite
the channels (6) and which provides the fibers and lints accumulating in the channels
(6) to be cleaned by delivering water into the channels (6) after the drying process.
[0015] The laundry washing and drying machine (1) of the present invention comprises the
condenser (7) disposed in an inclined manner at the upper side of the tub (3) such
that the condenser inlet (9) level is higher than the condenser outlet (10) level
(Figure 1).
[0016] Since the tub (3) is configured to be cylindrical and with horizontal axis, there
are spaces between the upper wall of the tub (3) and the ceiling of the laundry washing
and drying machine (1) body and these spaces are utilized by disposing the condenser
(7) at the upper side of the tub (3).
[0017] In an embodiment of the present invention, the condenser (7) has channels (6), extending
in an inclined manner from the condenser inlet (9) towards the condenser outlet (10)
in the flow direction of the processing air (PA), which provide the water condensed
therein during the drying process to flow downhill and the water delivered therein
by the spraying device (11) after the drying process to flow uphill countering gravity
and to leave the condenser (7) by partially flowing downhill.
[0018] In the laundry washing and drying machine (1), during the drying process, the processing
air (PA) passing over the laundry and becoming humid is delivered into the condenser
(7) above the tub (3) by passing from the tub outlet (8) by means of the air duct
(4) and is condensed by passing through the channels (6) in the condenser (7). The
condensate water collected in the channels (6) moves downhill inside the channels
(6) by the inclination of the channels (6) and the effect of the processing air (PA),
flows from the condenser outlet (10) to the air duct (4) and is discharged afterwards.
Since the water condensed in the channels (6) flows in the same direction as the processing
air (PA), it does not form resistance against the processing air (PA) flow. During
the drying process, the fibers and lints formed as the result of the laundry rubbing
against the drum (2) and each other pass through the tub outlet (8), being conveyed
by the processing air (PA), is carried upwards from the air duct (4) and accumulate
in the channels (6) inside the condenser (7). The spraying device (11) is operated
for cleaning the fibers and lints at the end of the drying process. The water delivered
by the spraying device (11) from the condenser outlet (10) provides the channels (6)
inside the condenser (7) to be cleaned of fibers and lints. The water delivered by
the spraying device (11) moves uphill from the lower end of the channels (6) at the
condenser outlet (10) towards the upper end thereof at the condenser inlet (9), traversing
all along the channels (6), flowing from the condenser inlet (9) to the air duct (4)
and from here to the tub (3) and is discharged afterwards.
[0019] In another embodiment of the present invention, the condenser (7) comprises a planar
ceiling (12) forming the upper surface of each channel (6) and a planar base (13)
forming the lower surface of each channel (6) and the spraying device (11) comprises
at least one spraying nozzle (14) called the "flat nozzle" that delivers water between
the ceiling (12) and the base (13) by forming a flat water beam.
[0020] In another embodiment of the present invention, the spraying device (11) comprises
spraying nozzles (14) that deliver water with the same inclination as the channels
(6) (Figure 1). In this embodiment, the water delivered from the spraying nozzles
(14) moves uphill in the channels (6) and a large amount of the water flows into the
air duct (4) by leaving from the condenser inlet (9).
[0021] In another embodiment of the present invention, the spraying device (11) comprises
spraying nozzles (14) that are positioned in an upward inclination such that water
is delivered to the ceiling (12) of the channels (6) (Figure 2). In this embodiment,
the water beam leaving the spraying nozzles (14) cleans the channels (6) by first
impacting the ceiling (12) of the channels (6). A larger portion of the water delivered
from the spraying device (11) moves uphill in the channels (6) and flows into the
air duct (4) from the condenser inlet (9). Some portion of the water impacting the
ceiling (12) of the channels (6) falls on the base (13) with the gravity effect and
moves downhill in the direction opposite to the direction delivered by the spraying
device (11) due to inclination of the channels (6) and flows into the air duct (4)
from the condenser inlet (10) by flushing the base (13) (Figure 2).
[0022] In another embodiment of the present invention, the portions of the air duct (4)
extending to the condenser inlet (9) and the condenser outlet (10) at the upper side
of the tub (3) are inclined in the same direction as the condenser (7) and the channels
(6) (Figure 1). Thus, the resistance formed structurally by the air duct (4) against
the flow of the processing air (PA) at the upper side of the tub (3) is decreased.
[0023] In another embodiment of the present invention, the laundry washing and drying machine
(1) comprises a first bend (15) disposed at the condenser inlet (9) side of the air
duct (4), a second bend (115) disposed at the tub outlet (8) side of the air duct
(4), at the lower side of the first bend (15), and the pressure of the water delivered
by the spraying device (11) is adjusted such that the channels (6) and the bends (15,
115) are washed sequentially. Consequently, the channels (6) and the bends (15, 115)
wherein the fibers and lints accumulate densely are washed by using a single spraying
device (11).
[0024] In another embodiment of the present invention, the laundry washing and drying machine
(1) comprises a reservoir (16) disposed on the air duct (4), at the condenser outlet
(10) side of the air duct (4), wherein the condensate water drained from the condenser
(7) and the fiber and lint cleaning water delivered from the spraying device (11)
to the condenser (7), that partially returns back due to inclination of the condenser
(7) are collected and a discharge line (17) that provides the water in the reservoir
(16) to be discharged.
[0025] In the laundry washing and drying machine (1) of the present invention, space is
gained by disposing the condenser (7) in an inclined manner at the upper side of the
tub (3) and utilizing the spaces at the upper side of the tub (3). The condenser (7)
channels (6) being inclined provides the water condensed in the channels (6) and the
water delivered from the spraying device (11) for cleaning the fibers and lints to
flow downhill, dripping off from the channels (6), the condensation efficiency of
the condenser (7) is increased, the fibers and lints accumulating in the condenser
(7) channels (6) and the bends (15, 115) in the air duct (4) can be cleaned effectively
by consuming a small amount of water.
[0026] It is to be understood that the present invention is not limited by the embodiments
disclosed above and a person skilled in the art can easily introduce different embodiments.
