has a condensing duct (11) connected, at its inlet and
outlet sections, to the washing tank (12) of the
dishwasher (10), an electric fan (13) positioned within
the duct (11) at an outlet (11u) of said duct (11) in
order to make an air-steam mixture (14) advance along

Description
The present invention refers to a device for drying the
dishes at the end of the washing process of a
dishwasher.
At the end of the washing process of a dishwasher, in
order to dry the dishes, it is necessary to evaporate
the water left on said dishes, and it is necessary that
the following conditions are met:
Therefrom, the need to reduce the steam content of the
air or to heat the air or to substitute the air
contained in the dishwasher with other air having a
lower steam content.
In order to condense the steam contained in the air,
said steam has to transfer heat to a body at a
temperature lower than the dew point temperature of the
air-steam mixture.
Some manufacturers use electric resistors to heat the
air inside the dishwasher and therefore to lower the
relative humidity, in order to enhance the drying
process.
The disadvantage of said process is the significant
consumption of electric energy. Then, the normal heat
dissipation towards the outside environment causes the
decrease of the temperature of the tank walls and the
condensing of the steam on said walls.
Other manufacturers use fans to draw the steam from the
dishwasher and to send it into the outside environment;
the so expelled air-steam mixture is substituted with
outside air which contains dust which can dirty the
dishes.
Another disadvantage of this process is the
introduction of steam and of odours into the
environment.
Further, this type of process is not suitable with the
integral built-in dishwashers in the kitchen furniture.
Other manufacturers use cold water in order to cool one
or more inside walls of the dishwasher whereon the
steam can condense; this solution has the advantage
that it does not consume any amount of energy, but the
lack of ventilation obstructs the water evaporation
from the dishes, since the air moves only because of
weak convective movements caused by the different
temperatures on the various tank walls.
The purpose of the present invention is to realise a
device to enhance the drying process of the dishes at
the end of the washing process of a dishwasher, said
device being free from the above described
disadvantages.
According to the present invention, a device for drying
the dishes at the end of the washing process of a
dishwasher is realised, said device is characterised by
comprising a condensing duct connected, at its inlet
and outlet sections, to the washing tank of the
dishwasher, a forced conduction device of an air-steam
mixture along said duct, and heat exchange means
positioned along the duct, and maintained at a
temperature substantially lower than the dew point
temperature of said mixture.
The invention will now be described making reference to
the attached drawings, which describe a non limiting
example of an embodiment, wherein:
- figure 1 shows, in a schematic way, a dishwasher provided with a first preferred embodiment of the device according to the invention;
- figure 2 is a schematic side elevation view of the device of figure 1;
- figure 3 is a schematic side elevation view of a second preferred embodiment of the device of figure 1;
- figure 4 is a front view of a third type of embodiment of the device of figure 1, said view has sectional views of some of the parts and some exploded parts for clarity sake;
- figure 5 is an enlarged perspective view, with some exploded parts for clarity sake, of a detail of figure 4; and
- figure 6 is a side elevation view of the device of figure 4, said view has sectional views of some of the parts and some exploded parts for clarity sake.
Referring to figure 1, numeral 1 indicates, as a whole,
a device for drying the dishes at the end of the
washing process of a dishwasher 10.
The device 1 comprises a condensing duct 11 which
extends outside a dish washing tank 12, and said duct
is fully positioned inside the dishwasher 10, and an
electric fan 13 suitable to feed an air-steam mixture
14 along said duct 11.
The duct 11 comprises an inlet 11i and an outlet 11u
directly connected to the tank 12, while the electric
fan comprises a fan 30 positioned within the duct 11,
substantially at the outlet 11u or along said duct 11,
and a driving motor 31 suitable to rotate the fan 30 so
as to draw the mixture 14 from the tank 12 and to make
said mixture advance in a feed direction D along said
duct 11.
The device 1 further comprises a water tank 16, which
is suitable to be filled with a certain amount of water
at the beginning of the drying process, and which is
provided with a heat exchange wall 15 positioned inside
the duct 11, and maintained at a temperature lower than
the dew point temperature of the air by said water. The
heat exchange between the mixture 14, which circulates
inside the duct 11, and the wall 15 causes the
condensing of at least a portion of the steam of said
mixture 14.
The size of said tank 16 is a function of the amount of
steam which needs to be condensed; in fact, since the
device 1 is a closed device, i.e. a device which does
not have any outside emissions, said device works by
using the water thermal capacity in order to accumulate
the steam condensing energy.
If the overall dimensions do not allow a sufficient
water capacity, it is possible to divide the drying
process by changing one or more times the warmed up
water load of the tank 16 with cool water.
In order to enhance the heat exchange, the wall 15 has
a sufficiently reduced thickness, while the
corresponding exchange surface 15s which faces the
inside of the duct 11 has an elevated exchange area. In
the non limiting example of embodiment shown in figure
2, the surface 15s has a bellows-like shape, but it can
have any other shape and it can be realised with any
kind of material.
As an alternative to water, the tank 16 can contain
other materials as, for instance, waxes, paraffin, some
phosphate salts, PCM (Phase Change Material), which
allow to accumulate heat through physical changes or
through endothermic chemical reactions.
No replacement is provided for these materials inside
the tank 16, and the heat accumulated in said materials
to maintain the wall 15 at a temperature lower than the
dew point temperature of the air is transferred to the
outside environment during the rest period of the
dishwasher 10 between the washing cycles, and, in order
to enhance the heat exchange between the outside
environment and the tank 16, the latter can be
installed, for instance, in an opening (not shown) of
the dishwasher 10.
Further, the device 1 comprises a feed opening 17 to
feed cool water to the tank 16, and a discharge opening
19 to discharge the heated water from said tank 16;
while the duct 11 is provided with a discharge outlet
18 for the condensate, which is collected by the
gravity force from the surface 15s at said discharge
outlet 18.
The discharge outlet 18 is connected alternatively to a
small well (not shown) in the dishwasher 10, or
directly to the tank 12, and, in this case, in order to
avoid flooding the duct 11 with the washing water, the
discharge outlet 18 is provided with a stop solenoid
valve (not shown and of a known type), or with a float
(not shown and of a known type) suitable to
automatically close said discharge outlet 18.
According to what is shown in figure 3, the tank 16
could also be defined by a bag 20 hermetically sealed
placed inside the duct 11 and which is not in contact
with said duct 11 so as to have its outer surface 15s
fully surrounded by the mixture 14.
Because of the partial condensing of the steam, the
air-steam mixture at the outlet 11u of the condensing
duct 11 has a lower steam content with respect to the
inlet conditions into said duct 11.
The position of the electric fan 13 used to circulate
the air is also important, in fact, by placing the
electric fan 13 at the outlet 11u of the condensing
duct 11, it is possible to maintain the pressure inside
said duct 11 at a value lower than the value of the
environment pressure because of the normal pressure
drops inside the ducts: this fact further enhances the
condensing since the pressure value influences the
saturation temperature. Further, by placing also the
motor 31 inside the duct 11 and by making the air,
before it goes back into the tank 12 of the dishwasher
10, get in touch and cool said motor 31, a partial
heating of the air itself is obtained with a consequent
further decrease of the relative humidity. The power
dissipated by the motor 31 is therefore used to further
enhance the drying process.
However, the electric fan 13 can be placed at any point
of the duct 11, according to the production needs,
without, for this reason, significantly jeopardising
the just described advantages with respect to the
positioning of said electric fan 13 at the outlet 11u.
Figures 4, 5 and 6 show a preferred embodiment of the
device 1, wherein, for reasons of overall dimensions,
the duct 11 is mounted laterally and below the tank 12,
and the electric fan 13 is placed inside the duct 11
and directly below the tank 12.
In particular, in order to avoid at the same time that
the washing water floods the duct 11, the inlet 11i is
provided with a vertical siphon 51, while the outlet
11u is provided with a corresponding vertical siphon
52, which is positioned on the same plane of the siphon
51 and the mixture 14 passes vertically through said
siphon 52 to reduce its speed and to enhance the heat
exchange with the wall 15, which defines a rear wall
both for the siphon 51 and for the siphon 52.
The fact that the two siphons 51 and 52 are integral
with the wall 15 allows to take the best advantage of
the available room by reducing to the minimum
requirements the overall dimensions of the device 1.
At least the fan 30 of the electric fan 31 is enclosed
in a fluid tight box 53, which defines an intermediate
portion of the duct 11, and it is positioned below the
tank 12, and it comprises an elbow shaped inlet 53i
connected to the siphon 52 in order to fully insulate
said electric fan 13 from the tank 12.
Said box comprises two side appendices, wherein the
appendix 54 defines an elbow shaped inlet duct for the
siphon 51, while the appendix 55 has an inlet duct 56
and an outlet duct 57 of the water from the tank 16. In
particular, the siphon 51 is substantially U-shaped and
has its concave portion facing downward, while the
siphon 52 has substantially an upside-down L shape and
extends from the outlet 53u until it reaches the outlet
11u, and it is provided with a plurality of inner bent
tiles 58 suitable to obstruct the free flow of the
mixture 14.
In the example of embodiment shown in figures 4, 5 and
6, the fan 30 is a fan which has an axial inlet flow
and a radial outlet flow in order to feed both the
outlet 53u and the appendix 54 so as to enhance the
circulation of the mixture 14 along the duct 11.
It is understood that the invention is not limited by
the herein described and shown embodiments, which have
to be considered as realisation examples of the device
1 for the drying process of the dishes, which is
instead suitable for further changes with respect to
part shapes and to part positioning, and to production
and assembly details.
