Definitions

  • the present invention relates to washer devices comprising steam generator.
  • 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.
  • 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.
  • 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.
  • 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.
  • a dishwasher and a control method of the same 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.
  • 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.
  • the washer device according to the present invention comprises the combined features of claim 1.
  • the steam generator is allowed to operate in conjunction with other components.
  • 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).
  • An object of the present invention is to provide a washer device comprising steam generator.
  • Another object of the present invention is to provide a washer device wherein the steam generator is able to operate in conjunction with other components.
  • Another object of the present invention is to provide a washer device that ensures that the steam generator included therein is cleaned while being used.
  • a further object of the present invention is to provide a washer device that heats the washing liquid without a heating unit or even if the heating unit therein fails.
  • a different object of the present invention is to provide a washer device that provides better cleaning of highly soiled articles.
  • Still another object of the present invention is to provide a reliable washer device.

  • 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.
  • 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).
  • 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).
  • 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).

  • 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.
  • 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.
  • the washing liquid received into the washing chamber (1) may be heated by means of the steam generator (5).
  • the need of the washer device (M) for an additional heater to heat the washing liquid is eliminated.
  • 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).
  • 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).
  • 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).
  • 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.
  • 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).

  • the steam generator (5) is cleaned efficiently.
  • 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.
  • the washing liquid received into the washing chamber (1) may be heated by means of the steam generator (5).
  • the need of the washer device (M) for an additional heater to heat the washing liquid is eliminated.
  • 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).
  • 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).
