Field of the Invention
[0001] The present invention relates to washer devices comprising steam generator.
Background Art
[0002] Washer devices especially such as dishwashers and washing machines may employ steam
generators, as known for example from
WO2008/147033A1, that facilitate washing process by softening the dried stains, for example. In the
said steam generators, liquid (i.e. mains water) received from a liquid source (i.e.
water mains) is heated and converted into steam. The obtained steam is introduced
into a washing chamber containing the washed articles, during the washing process
or prior to the washing process. Steam with a high temperature softens any stains
on the articles included in the washing chamber and ensures a simpler and more effective
washing process.
[0003] The washing liquid (i.e. water, a mixture of water and detergent) in the washer devices
is circulated throughout a washing process. The washing liquid collected at the bottom
of the washing chamber by means of gravity may be supplied to upper sections of the
washing chamber through a circulation system. The washing liquid may be heated, when
required, during the said circulation process. In this way, the washing liquid is
continuously maintained at the desired temperature during the washing process.
[0004] The state-of-art document
EP2031116A1 discloses a steam generator suitable for use in washer devices. Said steam generator
operates independent from the water control systems of the washer device (i.e. water
inlet/outlet systems and/or circulation system of the washer device). However, such
independent operation of the steam generator and water control system restricts functionality
of the washer device.
[0005] In another state-of-art document
US2008/236624A1 a dishwasher and a control method of the same is disclosed. The dishwasher comprises
a washing compartment, a water supply tube, a sump, a water discharge tube, a first
heater in the sump, a steam generator which operates independently from the first
heater, a circulation pump for pumping and spraying wash water in the collection chamber
to a rack via a spray arm. According to the invention of the document
US2008/236624A1, the washing water received from water supply tube is supplied to the steam generator
via line 260 and the washing water received from the sump is supplied to the steam
generator via line 328. Using two different lines increases complexity and production
cost of the dishwasher and also requires additional control processes in order to
regulate the washing water pass according to different washing operations.
Brief Description of the Invention
[0006] The washer device according to the present invention comprises the combined features
of claim 1.
[0007] In the washer device of the present invention, the steam generator is allowed to
operate in conjunction with other components. Thus, the steam generator and/or other
components are allowed to operate with different functions so as to meet disparate
needs of the users (for example, even if the heating unit of the washer device fails,
the washing liquid may be heated).

Description of the Invention
[0016] In the washer devices (i.e. dishwasher or washing machine etc.) that wash the articles
placed inside an inner chamber, steam generators are used which supplies steam onto
the articles to be washed in order to provide better cleaning of especially dried
stains on the articles. Said steam generators operate as a separate unit in the washer
device. This results in a restriction in the operation functionalities of the steam
generator and thus the washer device. Therefore, with the present invention, there
is provided a washer device wherein the steam generator is able to operate in conjunction
with other components.
[0017] The washer device (M) according to the present invention, as illustrated in figures
1-6 as a dishwasher, comprises at least one washing chamber (1) wherein the articles
to be washed are placed and the washing process is performed; at least one washing
liquid inlet (2) through which washing liquid (i.e. water from the mains) for washing
and/or rinsing processes is received; at least one collection chamber (3) which is
located under the washing chamber (1) and wherein the washing liquid received from
the washing liquid inlet (2) is collected; at least one washing liquid outlet (4)
which is connected with the said collection chamber (3) and which discharges the liquid
collected in the collection chamber (3) at the end of the washing and/or rinsing process;
and at least one steam generator (5) which heats the washing liquid received from
the said washing liquid inlet (2) and/or collection chamber (3) and supplies it into
the washing chamber (1) through at least one steam inlet (6) connected with the washing
chamber (1). Said steam generator (5) is preferably positioned in alignment with the
bottom of the washer chamber (1). Since the said steam generator (5) heats the washing
liquid received from the washing liquid inlet (2) and/or collected in the collection
chamber (3) and supplies it into the washing chamber (1), the steam generator (5)
may be used for different functions.
[0018] As shown in figures 1-3, 5 and 6, the washer device (M) of the present invention
further comprises at least a first T connection (7) which is connected at one side
with the washing liquid inlet (2), and at another side, with the collection chamber
(3) and at the other, with the steam generator (5) and which supplies the washing
liquid received from the washing liquid inlet (2) into the collection chamber (3)
and the steam generator (5). In this embodiment, the washing liquid supplied into
the washer device (M) is, at the same time, sent to the collection chamber (3) and
the steam generator (5). Here, when the washing liquid received into the washer device
(M) reaches to a liquid level (a), and then the washing liquid has filled the collection
chamber (3) and reached to the level of the steam generator (5). In this way, the
steam generator (5) is operated to boil the water, so it is used to heat the washing
liquid in the collection chamber (3) in addition to supplying hot steam into the washing
chamber (1). With this embodiment, a direct connection between the steam generator
(5) and the collection chamber (3) is established and accordingly, instead of the
washing liquid that is boiled and evaporated in the steam generator (5) and sent to
the washing chamber (1), the washing liquid in the collection chamber (3) is refilled
into the steam generator (5) by means of gravity. In this way, the steam generator
(5) is able to perform a heating process in a continuous manner.
[0019] As shown in figure 3, the washer device (M) also comprises at least one steam generator
pump (12) which is interposed between the said first T connection (7) and the steam
generator (5) and which allows the washing liquid in the collection chamber (3) to
pass through the steam generator (5) into the washing chamber (1). With the said steam
generator pump (12), the washing liquid in the collection chamber (3) is heated in
the steam generator (5) and sent to the washing chamber (1) during the operation of
the washer device (M). Here, the washing liquid received from the collection chamber
(3) is able to be turned into a hot washing liquid in the steam generator (5) and
sent to the washing chamber (1) in case the steam generator pump (12) is operated.
Since the washing liquid circulated by means of the steam generator pump (12) will
have a higher temperature while being passed through the steam generator (5), if highly
soiled articles are placed into an area close to the steam inlet (6), the washing
liquid will initially strike on these articles so that such articles may be cleaned
more efficiently. In case the steam generator pump (12) is optionally (according to
a program) not operated, the steam generator (5) only generates steam and the washing
liquid received from the collection chamber (3) is introduced into the washing chamber
(1) as a steam. Thus, the washing liquid received into the washing chamber (1) may
be heated by means of the steam generator (5). Furthermore, the need of the washer
device (M) for an additional heater to heat the washing liquid is eliminated.
[0020] Yet the washer device (M) of the present invention comprises at least one circulation
pump (10) that supplies the washing liquid collected in the collection chamber (3)
into the washing chamber (1). In this embodiment, the washer device (M) also preferably
comprises at least one heating unit (11) which is interposed between the circulation
pump (10) and the washing chamber (1) and which heats the washing liquid supplied
into the washing chamber (1). Although the washing liquid is heated by the steam generator
(5) in the washer device (M) provided with a single steam generator (5) used in figures
1-4, the heating unit (11) may be used in order to extend the lifetime of the steam
generator (5), in particular, and to reduce the washing time. In case the said heating
unit (11) fails, the washing liquid is heated by the steam generator (5). Particularly,
in case at least two steam generators are used, as shown in figures 5 and 6, the heating
unit (11) may totally eliminated and the washing liquid may heated by the steam generators
(5). Furthermore, with the use of at least two steam generators (5), an intensive
steam is generated and the time for heating the water is reduced.
[0021] In a preferred embodiment of the invention as shown in figure 2, the washer device
(M) comprises at least one valve (3a) for collection chamber which is interposed between
the said first T connection (7) and the collection chamber (3) and which controls
the washing liquid supplied from the first T connection (7) into the collection chamber
(3). In this embodiment, when feeding washing liquid into the washer device (M) through
a washing liquid inlet (2), for example, the valve (3a) for the collection chamber
is switched into a closed position so as to feed the entire washing liquid into the
washer chamber (1) via the steam generator (5). Thus, while feeding liquid into the
washing chamber (1) through the washing liquid inlet (2) (for example, while feeding
water from the mains), the steam generator (5) is cleaned efficiently. After the washing
liquid is received, the valve (3a) for the collection chamber is switched into an
opened position and thus the washing liquid in the collection chamber (3) is filled
into the steam generator (5) by means of gravity.
[0022] Thanks to the abovementioned embodiments, the washing liquid received into the washing
chamber (1) may be heated by means of the steam generator (5). With this embodiment,
the need of the washer device (M) for an additional heater to heat the washing liquid
is eliminated.
[0023] In another preferred embodiment of the invention, the washer device (M) comprises
at least one outlet pump (14) that supplies the washing liquid collected in the collection
chamber (3) into the washing liquid outlet (4). In this embodiment, the washer device
(M) also comprises at least a second T connection (13) which is connected at one side
with the outlet pump (14), and at another side, with the washing liquid outlet (4)
and at the other, with the steam generator (5); at least one outlet valve (4a) which
is interposed between the second T connection (13) and the washing liquid outlet (4)
and which controls liquid passage between the second T connection (13) and the washing
liquid outlet (4); and at least one steam generator valve (5a) which is interposed
between the second T connection (13) and the steam generator (5) and which controls
liquid passage between the second T connection (13) and the steam generator (5). In
this embodiment, while the washer device (M) receives washing liquid or the washer
device (M) is being operated, the outlet valve (4a) is in its closed position and
the steam generator valve (5a) is in its opened position. Thus, the outlet pump (14)
supplies the washing liquid in the collection chamber (3) into the washing chamber
(1) via the steam generator (5). In order to discharge the washing liquid inside the
collection chamber (3) from the washer device (M), the outlet valve (4a) is brought
into an opened position and the steam generator valve (5a) is brought into a closed
position. Alternatively, the washer device (M) comprises at least one three-way valve
(not shown) which is connected at one side with the outlet pump (14), and at another
side, with the washing liquid outlet (4) and at the other, with the steam generator
(5), and which selectively supplies the washing liquid fed by the outlet pump (14)
into the steam generator (5) or the washing liquid outlet (4). Since the washing liquid
circulated by means of the outlet pump (14) will have a higher temperature while being
passed through the steam generator (5), if highly soiled articles are placed into
an area close to the steam inlet (6), the washing liquid will initially strike on
these articles so that such articles may be cleaned more efficiently. Furthermore,
the washing liquid received into the washing chamber (1) may be heated by means of
the steam generator (5) and the need of the washer device (M) for an additional heater
to heat the washing liquid is eliminated.
[0024] In an illustrative embodiment of the invention, the washer device (M) comprises at
least one inlet filter (8) which filters the washing liquid received from the washing
liquid inlet (2) before it is sent to the collection chamber (3) and/or steam generator
(5). Thanks to the inlet filter (8) which is preferably in the form of a resin container,
foreign substances (i.e. scale) contained in the washing liquid received into the
washer device (M) are removed.
[0025] In another illustrative embodiment of the invention, the washer device (M) comprises
at least one inlet valve (9) connected with the washing liquid inlet (2) for receiving
the washing liquid from the washing liquid inlet (2) in a controlled manner.
[0026] A method for operation of the above-mentioned washer device (M) comprises the steps
of receiving the washing liquid through the washing liquid inlet (2); supplying the
washing liquid received from the washing liquid inlet (2) into the washing chamber
(1) by means of the steam generator (5) and the collection chamber (3); and finishing
the receiving of the washing liquid through the washing liquid inlet (2) when the
liquid in the washing chamber (1) has reached to a predetermined liquid level (a).
In this embodiment, since the washing liquid received from the washing liquid inlet
(2) is passed through the steam generator (5), the steam generator (5) is also cleaned.
[0027] Another method for operation of the above-mentioned washer device (M) comprises the
steps of receiving the washing liquid through the washing liquid inlet (2); supplying
the washing liquid received from the washing liquid inlet (2) into the washing chamber
(1) by means of the steam generator (5); and finishing the receiving of the washing
liquid through the washing liquid inlet (2) when the liquid in the washing chamber
(1) has reached to a predetermined liquid level (a). In this embodiment, since the
washing liquid, in total (or almost in total), is passed through the steam generator
(5) and into the washing chamber (1), the washing liquid supplied into the washing
chamber (3) is heated in the steam generator (5), when necessary. Here, supply of
the washing liquid into washing chamber (1) by means of the steam generator (5) is
performed by closing the said valve (3a) for the collection chamber and/or operating
the steam generator pump (12).
[0028] A further method for operation of the above-mentioned washer device (M) comprises
the step of supplying the washing liquid accumulated in the collection chamber (3)
into the washing chamber (1) by being passed through the steam generator (5). In this
embodiment, the washing liquid accumulated in the collection chamber (3) is passed
through the steam generator (5) using the steam generator pump (12) or outlet pump
(14). By passing the washing liquid through the steam generator (5), the washing liquid
is heated or converted into steam so as to be supplied into the washing chamber (1).
[0029] In the washer device (M) of the present invention, the steam generator (5) is allowed
to operate in conjunction with other components. Thus, the steam generator (5) and/or
other components are allowed to operate with different functions so as to meet disparate
needs of the users (for example, even if the heating unit of the washer device fails,
the washing liquid may be heated).
