Technical Field
[0001] The present invention relates to a dish washing machine, and more particularly, to
a dish washing machine that is capable of preventing moisture from being formed on
a bottom or a wall around the bottom of the dish washing machine and preventing the
bottom or the wall of the dish washing machine from being deformed due to the moisture.
Background Art
[0002] A related art dish washing machine sprays washing water on dishes placed in a tub
to remove foreign matter, such as food waste left on the dishes, thereby automatically
washing the dishes. Further, the operation of the dish washing machine generally includes
a washing cycle for spraying washing water mixed with detergent in the tub containing
the dishes to remove the foreign matter left on the dishes, a rinsing cycle for spraying
washing water not mixed with the detergent in the tub to remove the remaining foreign
matter and the detergent after performing the washing cycle, and a drying cycle for
drying the dishes.
[0003] Some dish washing machines use heated washing water or that spray steam during the
washing cycle or during the rinsing cycle to further increase the washing effect.
For example, FIG. 1 illustrates a related art dish washing machine.
[0004] As shown in FIG. 1, the related art washing machine includes a case 100 forming the
external appearance of the dish washing machine, and a door 120 for opening and closing
the case 100. A tub 150 is also mounted in the case 100 and defines a space for receiving
dishes to be washed. Further, a sump 200 is mounted below the tub 150 for storing
washing water.
[0005] In addition, the tub 150 includes shelves 160 and 170 for holding the dishes and
spray arms 220 and 230 for spraying water toward the shelves 160 and 170. Further,
and as shown in FIG. 1, the washing machine also includes a fan 90 and exhaust duct
92 mounted at the door 120. The fan 90 and exhaust duct 92 remove wet air from the
tub 150. In more detail, the exhaust duct 92 extends to a lower part of the dish washing
machine and guides air exhausted by the fan 90 out of the dish washing machine.
US 2006/0236556 A1 relates to a dishwasher having a particular drying cycle. The dishwasher door includes
a vent channel connecting the interior of the dishwasher to the outside and housing
a condenser section that condenses water vapour from moisture laden air from the interior
of the dishwasher and directs the condensed water back into the dishwasher. A vent
valve covers the opening of the vent channel into the dishwasher and is opened and
closed at appropriate times during the drying cycle. A heater adjacent a blower heats
air entering the dishwasher. A temperature sensor in the dishwasher interior provides
temperature measurements of the inside of the dishwasher that may be used to control
the duration of the drying cycle. A controller interconnects the operating components
of the dishwasher and provides the logic for the drying cycle.
Disclosure of Invention
Technical Problem
[0006] However, the related art dish washing machine has the following problems.
[0007] First, as shown in FIG. 2, the dish washing machine is generally installed in a kitchen
in a built-in structure together with other articles of kitchen furniture "f", such
as a sink, stove, etc. As a result, the opposite sides and the rear of the dish washing
machine are closed and only the front of the dish washing machine having the door
is unob-structed.
[0008] Further, the exhaust duct 92 extends to the lower part of the dish washing machine,
and therefore air is exhausted out of the dish washing machine through the lower part
of the dish washing machine. However, and with reference to FIGs. 1 and 2, some of
the exhausted is not exhausted through the front of the dish washing machine, but
rather flows to the rear and the sides of the dish washing machine.
[0009] Then, when the exhausted air flows to the rear and the sides of the dish washing
machine, the air is not exhausted from the dish washing machine, because the rear
and the sides of the dish washing machine are closed. As a result, the walls of the
kitchen furniture "f', installed adjacent to the sides of the dish washing machine
or the installation surfaces of the dish washing machine become deformed due to the
relatively high-temperature, high-humidity air. Furthermore, the relatively high-temperature,
high-humidity air is introduced into a gap defined between the bottom of the dish
washing machine and the floor where the dish washing machine is installed, with the
result that the bottom of the dish washing machine becomes covered with rust.
Technical Solution
[0010] Accordingly, one object of the present invention is directed to a dish washing machine
that substantially obviates one or more problems due to limitations and disadvantages
of the related art.
[0011] Another object of the present invention is to provide a dish washing machine that
is capable of preventing moisture from being formed on the bottom or the wall around
the bottom of the dish washing machine and preventing the bottom or the wall of the
dish washing machine from being deformed due to the moisture.
[0012] To achieve these objects and other advantages and in accordance with the purpose
of the invention, as embodied and broadly described herein, the present invention
provides in one aspect a dish washing machine including a tub configured to form a
space for a dish to be washed, a door configured to open or close the tub, and an
exhaust duct extended to an under portion of the door to exhaust air in the tub. Further,
the exhaust duct has a lower end sloped with respect to an installation surface of
the dish washing machine.
[0013] In another aspect, the present invention provides a dish washing machine including
a tub configured to form a space for a dish to be washed, a door configured to open
or close the tub, and an exhaust duct configured to exhaust air in the tub to an under
portion of the door and toward an opening direction of the door.
[0014] Further scope of applicability of the present invention will become apparent from
the detailed description given hereinafter. However, it should be understood that
the detailed description and specific examples, while indicating preferred embodiments
of the invention, are given by illustration only, since various changes and modifications
within the scope of the invention will become apparent to those skilled in the art
from this detailed description.
Advantageous Effects
[0015] As apparent from the above description, the present invention has several advantages.
[0016] First, the air exhausted from the exhaust duct is directed in the opening direction
of the door, and therefore, the air flows toward the open front of the dish washing
machine. Consequently, the air is smoothly exhausted out of the dish washing machine
without the introduction of the air to the sides and the rear of the dish washing
machine, whereby the formation of moisture on the installation surface of the dish
washing machine is minimized. In addition, the high-temperature air is smoothly exhausted
out of the dish washing machine, and therefore, the deformation of the installation
surface of the dish washing machine due to heat is minimized.
[0017] Secondly, the air exhausted from the exhaust duct flows toward the vertical center
line of the door of the dish washing machine. Consequently, the flow of the air exhausted
from the exhaust duct to the sides of the dish washing machine is prevented, whereby
it is possible to solve the problems which may occur due to the contact of the high-temperature,
high-humidity exhausted air with the walls of kitchen furniture installed at the sides
of the dish washing machine.

Best Mode for Carrying Out the Invention
[0025] Reference will now be made in detail to the preferred embodiments of the present
invention, examples of which are illustrated in the accompanying drawings. Wherever
possible, the same reference numbers will be used throughout the drawings to refer
to the same or like parts.
[0026] FIG. 3 is a sectional view illustrating a fan and a fan housing of a dish washing
machine according to an embodiment of the present invention. As shown in FIG. 3, the
dish washing machine includes the case 100 forming the external appearance of the
dish washing machine, the door 120 for opening and closing the case 100, the tub 150,
the shelves 160 and 170, and the spray arms 220 and 230. These components are similar
to those of the previously-described related dish washing machine, are denoted by
the same reference numerals, and therefore a detailed description thereof is omitted.
[0027] In addition, as shown in FIG. 3, the dish washing machine also includes a control
panel 130 and a sump 205. Further, the sump 205 includes a pump 210 for pumping washing
water and a filter (not shown) for filtering the washing water. The sump 205 also
includes a sump heater 290 for heating the washing water.
[0028] In addition, the sump 205 is connected to a first water supply pipe 250, through
which fresh water is supplied from an external water source, and a drainage pipe 270,
through which the washing water in the sump 205 is drained to an outside of the washing
machine. A first water supply valve 255 for controlling the supply of water into the
sump 205 is also mounted on the sump 205.
[0029] Further, the upper shelf 160 and the lower shelf 170 are mounted at the upper part
and the lower part of the tub 150, respectively. Also, the upper spray arm 230 and
the lower spray arm 220 are mounted at the upper part and the lower part of the tub
150 for spraying the water pumped by the pump 210 toward the upper shelf 160 and the
lower shelf 170, respectively.
[0030] In addition, a top nozzle 240, for spraying the water pumped by the pump 210 from
the upper part to the lower part of the tub 150, is mounted in the upper part of the
tub 150. A connecting pipe 110 connects the pump 210 and the top nozzle 240. Further,
in one embodiment, steam may be also sprayed or supplied into the tub 150 by the pump
210 and the spray arms 230 and 220 in addition to the washing water sprayed into the
tub 150. In more detail, the washing machine includes a steam generator 300 which
is driven separately from the sump heater 290 mounted in the sump 205.
[0031] As shown in FIG. 3, the steam generator 300 communicates with a second water supply
pipe 260 and also communicates with the tub 150 via a steam supply pipe 280. A second
water supply valve 265 for controlling the supply of water into the steam generator
300 is also mounted on the second water supply pipe 260.
[0032] In addition, the steam generator 300 includes a steam heater 310 for heating water
supplied into the steam generator 300 and a water level sensor 320 for sensing the
water level in the steam generator 300. The water level sensor 320 may sense, for
example, a low water level and a high water level.
[0033] In more detail, the low water level is established to protect the steam heater 310,
and the high water level is established to prevent the overflow of the water supplied
into the steam generator 300 from the steam generator 300. Also, the steam generator
300 may further include a steam supply valve (not shown) for controlling the opening
and closing of the steam supply pipe 280 to supply steam at a desired time.
[0034] In addition, the dish washing machine may further include a contamination sensor
(not shown) for sensing a contamination degree of washing water used to wash the dishes.
For example, the contamination sensor may be mounted at one side of the sump 205 for
sensing the contamination degree of washing water circulating in the tub.
[0035] Further, a control unit (not shown) for controlling the dish washing machine is electrically
connected to electrically-operating components, such as the control panel 130, the
pump 210, and the steam generator 300, to control the operation of the dish washing
machine. In addition, the upper side of the tub 150 includes mounted components for
exhausting high-temperature wet air in the tub 150, heated by the steam and the heated
washing water, out of the dish washing machine.
[0036] As shown in FIGs. 3 and 4, the component for exhausting air inside the washing machine
includes an exhaust fan 390 for suctioning high-temperature wet air from the tub 150,
a housing 394 defining a space for receiving the exhaust fan 390, and an exhaust duct
392 for guiding the high-temperature wet air, suctioned by the exhaust fan 390, out
of the dish washing machine.
[0037] Further, the exhaust fan 390 may be a bidirectional suction fan. Specifically, the
exhaust fan 390 suctions the high-temperature wet air from the tub 150 into the housing
394, and, at the same time, suctions low-temperature, low-humidity air from the outside
into the exhaust duct 392, such that the condensation of moisture is performed in
the housing 394 or the exhaust duct 392.
[0038] Consequently, the amount of moisture contained in the exhausted air is reduced, and
the temperature of the exhausted air is also lowered. Accordingly, the formation of
moisture on the installation surface of the dish washing machine and the walls of
the furniture installed adjacent to the dish washing machine are minimized.
[0039] Of course, the present invention is not limited to the above-described construction.
For example, the exhaust fan 390 according to an embodiment of the present invention
may be configured to suction and exhaust only the air in the tub 150. Further, the
exhaust duct 392 may be coupled to one side of the housing 394 such that the exhaust
duct 392 communicates with the housing 394.
[0040] Also, as shown in FIG. 4, the exhaust duct 392 extends downward through the interior
of the door 120 toward the installation surface of the dish washing machine. Consequently,
air exhausted from the housing 394 is exhausted to the lower part of the door 120
along the exhaust duct 392. The exhaust duct 392 also includes ribs 399 for guiding
the flow of air exhausted from the exhaust duct 392.
[0041] Next, FIG. 5 is a perspective view illustrating the exhaust duct 392 according to
an embodiment of the present invention, and FIG. 6 is a sectional view illustrating
the lower end of the exhaust duct of FIG. 5.
[0042] As shown in FIG. 5, one side of the middle part of the exhaust duct 392 includes
a water recovering hole 393, which communicates with the tub 150 for recovering water
flowing in the exhaust duct 392 to the tub 150. As shown in FIGS. 5 and 6, the exhaust
duct also includes a first bent part 397 such that a lower end 391 of the exhaust
duct 392 is inclined at a predetermined angle with respect to the installation surface
of the dish washing machine.
[0043] In addition, the first bent part 397 is formed adjacent to the lower end 391 of the
exhaust duct 392. Consequently, the lower end 391 of the exhaust duct 392 is inclined
at the predetermined angle to the installation surface of the dish washing machine
such that the lower end 391 of the exhaust duct 392 is directed in the direction in
which the door 120 is directed (i.e., the direction in which the door 120 is opened).
[0044] Further, one reason why the lower end 391 of the exhaust duct 392 is directed in
the direction in which the door 120 is directed is as follows. When the dish washing
machine is installed in a built-in structure, the opposite sides of the dish washing
machine are closed by the sides of the kitchen furniture "f" (see FIG. 2), the rear
of the dish washing machine is also closed by the wall, and an open space for opening
and closing the door 120 is formed at the front of the dish washing machine. Therefore,
the lower end 391 of the exhaust duct 392 is directed to the open space in the direction
in which the door 120 is directed such that air exhausted from the exhaust duct 392
is exhausted toward the open space.
[0045] As described above, the exhaust duct 392 is mounted in the door 120. In addition,
the door 120 includes various parts, such as a frame for maintaining the strength
of the door 120 and a noise isolation member for isolating noise. As a result, the
interior space of the door 120 is limited. Consequently, as shown in FIG. 6, the exhaust
duct 392 is mounted in the door 120, such that the exhaust duct 392 is in tight contact
with the inside of a panel 122 constituting the front of the door 120, for maximum
spatial utilization.
[0046] However, when the exhaust duct 392 having the first bent part 397 is mounted in the
door 120 such that the exhaust duct 392 is in tight contact with the inside of the
panel 122, the lower end 391 of the exhaust duct 392 protrudes outward from the front
of the dish washing machine by the first bent part 397, which reduces the aesthetical
appearance of the dish washing machine.
[0047] Consequently, as shown in FIG. and 6, the exhaust duct 392 includes a second bent
part 398 at the exhaust duct 392 such that the inclined lower end 391 of the exhaust
duct 392 is located in the door 120 of the dish washing machine. In addition, the
second bent part 398 is formed at the upper side of the first bent part 397 of the
exhaust duct 392. In more detail, the second bent part 398 is bent at least once in
the rearward direction of the door 120, which is opposite to the direction in which
the first bent part 397 is bent. Consequently, the first bent part 397, which is inclined
to be directed toward the door 120, does not protrude outward from the dish washing
machine, thereby increasing the aesthetical appearance of the dish washing machine.
[0048] That is, the exhaust duct 392 is formed such that the second bent part 398 is bent
in the direction opposite to the direction in which the door 120 is opened, and the
first bent part 397 is bent in the direction in which the door is opened.
[0049] In addition, the present invention is not limited to the above-described construction.
For example, when the inner space of the door 120 is sufficient, the exhaust duct
392 may be spaced by the protruding length of the inclined lower end 391 of the exhaust
duct 392 from the panel 122 constituting the front of the door 120.
[0050] In addition, as discussed above, the exhaust duct 392 shown in FIG. 4 includes the
ribs 399 for guiding the flow of air exhausted from the exhaust duct 392. That is,
one or more ribs 399 are preferable formed at the lower end 391 of the exhaust duct
392. The ribs 399 are also preferably inclined such that exhausted air flows not toward
the sides of the dish washing machine, but toward a vertical center line C of the
door 120 as shown in FIG. 4.
[0051] That is, as shown in FIG. 4, the vertical center line C of the door 120 is an imaginary
perpendicular line drawn perpendicularly to the installation surface at the outer
middle part of the door 120. In addition, the ribs 399 being inclined minimizes the
contact of the air exhausted from the exhaust duct 392 with the sides of the kitchen
furniture located at the sides of the dish washing machine.
[0052] In addition, the present invention is not limited to the above-described construction.
For example, the lower end of the exhaust duct may be inclined toward the vertical
center line of the door.
[0053] Meanwhile, as shown in FIG. 4, the exhaust duct 392 is mounted in the door 120, and
preferably, the exhaust duct 392 is mounted in the door 120 such that the exhaust
duct 392 is deviated to the left side or the right side when viewed from the front.
The following description will be given on the assumption that the exhaust duct 392
is deviated to the left side.
[0054] In more detail, to reduce the flow loss of the air flowing in the exhaust duct 392,
and as shown in FIGS. 4 and 5, the exhaust duct 392 is preferably formed such that
the air is gradually diffused during the flow of the air in the exhaust duct 392.
In addition, a sectional area of the exhaust duct 392 is gradually widened so the
air is diffused in the exhaust duct.
[0055] Also, when the exhaust pressure of the air exhausted from the exhaust duct 392 is
too low, the air is mixed with external air, the air is not sufficiently exhausted
out of the dish washing machine, and is then diffused toward the bottom, the installation
surface, and the sides of the dish washing machine. Consequently, an appropriate exhaust
pressure is preferred.
[0056] In more detail, an appropriate exhaust pressure is related to the distance between
the lower end 391 of the exhaust duct 392 and the outer surface of the door 120 of
the dish washing machine, the sectional area and shape of the exhaust duct 392, and
the blowing pressure of the exhaust fan 390. However, these factors may be changed
depending upon the size or model of the dish washing machine.
[0057] As previously described, the frame for maintaining the strength of the door and various
components for noise isolation and watertightness are mounted in the door 120, with
the result that the inner space of the door 120 is very small. Consequently, the cross
section of the exhaust duct 392 is preferably gradually lowered along the downward
direction of the exhaust duct 392, whereas the width of the exhaust duct 392 is gradually
increased along the downward direction of the exhaust duct 392, to avoid interference
with the components and to diffuse the air flowing in the exhaust duct 392.
[0058] Specifically, the cross section of an inlet end of the exhaust duct 392, which is
coupled to the housing 394, is higher than the cross section of the lower end 391
of the exhaust duct 392 through which air is exhausted. Also, the width of the inlet
end of the exhaust duct 392 coupled to the housing 394 is greater than the width of
the lower end 391 of the exhaust duct 392 through which air is exhausted.
[0059] In addition, as shown in FIG. 5, the exhaust duct 392 is also preferably formed in
a structure in which the exhaust duct 392 has a step part 395 at least once such that
the cross section of the exhaust duct 392 is gradually decreased along the downward
direction of the exhaust duct 392.
[0060] In addition, the step part 395 is preferably formed to avoid interference with the
components mounted in the door 120. Also, the step part 395 may be formed to serve
as a guide 396 for guiding the water flowing in the exhaust duct 392 to the water
recovering hole 393 along the step part 395.
[0061] In addition, when the step part 395 is formed to serve as the guide 396, the top
of the step part 395 is preferably formed to be inclined downward toward the water
recovering hole 393. Specifically, the water flowing along the inside of the exhaust
duct 392 is guided to the water recovering hole 393 along the guide 396 of the step
part 395.
[0062] As previously described, the cross section of the exhaust duct 392 is gradually lowered
along the downward direction of the exhaust duct 392, whereas the width of the exhaust
duct 392 is gradually increased along the downward direction of the exhaust duct 392.
[0063] Further, the side (i.e., the right side) of the exhaust duct 392 facing the imaginary
vertical center line C of the door 120 of the right and left sides of the exhaust
duct 392 is preferably gradually inclined toward the vertical center line C of the
door 120 along the downward direction of the exhaust duct 392.
[0064] Also, the side (i.e., the left side) of the exhaust duct 392 opposite to the side
of the exhaust duct 392 facing the vertical center line C of the door 120 of the right
and left sides of the exhaust duct 392 is preferably substantially formed perpendicularly
to the installation surface. In addition, the point where the right side of the exhaust
duct 392 starts to be inclined may be located above the middle height of the exhaust
duct 392.
[0065] Further, because the right side of the exhaust duct 392 is inclined toward the vertical
center line C of the door 120, and the left side of the exhaust duct 392 is substantially
formed vertically, the width of the exhaust duct 392 is gradually increased along
the downward direction of the exhaust duct 392. Consequently, the air flowing in the
exhaust duct 392 is gradually diffused during the movement of the air to the lower
end 391 of the exhaust duct 392, whereby flow loss or noise is reduced.
[0066] Also, the air exhausted from the exhaust duct 392 has inertia in which the air will
diffuse in the exhaust duct 392. Consequently, the air exhausted from the exhaust
duct 392 is exhausted toward the vertical center line C of the door 120, and therefore,
the formation of moisture on the sides of the furniture located at the sides of the
dish washing machine is minimized.
[0067] Consequently, the air in the tub of the dish washing machine according to an embodiment
of the present invention is exhausted outside through the following process. In more
detail, when the exhaust fan 390 is operated, high-temperature, high-humidity air
in the tub 150 is suctioned into the housing 394 and is guided to the exhaust duct
392 by the exhaust fan 390.
[0068] In addition, the side of the exhaust duct 392 facing the vertical center line C of
the door 120 is inclined in the direction in which the exhaust duct 392 is widened.
Consequently, the air flowing in the exhaust duct 392 is diffused in the direction
in which exhaust duct 392 is widened, whereby flow loss or noise is reduced.
[0069] Meanwhile, moisture contained in the air is condensed in the exhaust duct 392 such
that condensed water flows in the exhaust duct 392. Further, the condensed water flows
along the inside of the exhaust duct 392, is guided to the water recovering hole 393
along the guide 396 formed at the step part 395, and is collected in the tub 150.
[0070] Also, the flow direction of air in the exhaust duct 392 is bent at the second bent
part 398 of the exhaust duct 392 in the direction opposite to the direction in which
the door is directed, and is bent at the first bent part 397 of the exhaust duct 392
in the direction in which the door is directed, i.e., in the opening direction of
the door. Consequently, the air is exhausted from the exhaust duct 392 toward the
front of the dish washing machine such that the flow direction of the air is at a
predetermined angle to the installation surface.
[0071] In addition, because the ribs 399 are formed at the lower end 391 of the exhaust
duct 392, the air is exhausted toward the vertical center line C of the door 120.
As a result, the air is smoothly exhausted out of the dish washing machine without
contact of the air with the furniture located at the sides of the dish washing machine.
[0072] It will be apparent to those skilled in the art that various modifications and variations
can be made in the present invention without departing from the scope of the inventions.
Thus, it is intended that the present invention covers the modifications and variations
