Definitions

  • the invention relates to a steam ironing device according to the preamble of patent claim 1 and a method for operating a steam ironing device.
  • the known steam ironing devices comprise a water reservoir for storing water, at least one steam generator connected to the water reservoir for the generation of steam and a soleplate connected to the steam generator for treating the item to be ironed, the soleplate having at least one steam outlet opening for impinging on the item which has water vapour.
  • the document EP 3 269 873 A1 describes a known ironing station with different levels of steam, which consists of an iron with a soleplate and a supply unit with a water tank.
  • the iron further comprises a first evaporation chamber, which is separate from the soleplate and communicates with first steam outlet holes in the soleplate, a second evaporation chamber, which is integrated into the soleplate and communicates with steam outlet holes in the soleplate, and heaters that connect the soleplate and heat the vaporization chambers.
  • a first pump drives water through a main channel from the reservoir to the first vaporization chamber.
  • a second pump drives water through a secondary passage from a branch of the main passage located downstream of the first pump to the second vaporization chamber.
  • the invention therefore addresses the problem of improving a steam ironing device and a method for its operation.
  • a steam ironing device having the features of patent claim 1, which is characterized in that the steam ironing device has a plurality of steam generators and a controller for controlling the individual steam generators to generate steam and/or to release steam from the respective steam generator on the soleplate, the steam generators being controllable by means of the controller in such a way that steam can be emitted to the soleplate by means of at least one of the steam generators, while steam can be generated simultaneously by means of at least one other of the steam generators. Furthermore, this problem is solved by a method for operating a steam ironing device having the features of patent claim 6 .
  • the steam ironing device according to the invention can be designed as a steam ironing device for the household or for professional use, ie commercial operation.
  • the steam ironing device can be designed, for example, as a hot mangle or as a steam ironing station with a steam iron and/or a steam brush.
  • the soleplate can be designed in a correspondingly versatile way.
  • the wording “control for controlling the individual steam generators” is broad to be interpreted and thus includes, in addition to a controller in the regulatory sense, also a regulation of the individual steam generators in the regulatory sense.
  • the advantage that can be achieved with the invention is, in particular, that a steam ironing device and a method for operating a steam ironing device are improved. Due to the inventive design of the steam ironing device and the method for operating a steam ironing device, it is possible to supply steam with a substantially constant steam pressure and/or a substantially constant amount of steam to an item to be ironed by means of the soleplate during the entire steam ironing process. The item to be ironed is thus supplied with steam at an essentially constant steam pressure and/or essentially constant amount of steam during the entire treatment time of the item to be ironed.
  • the plurality of steam generators of the steam ironing device according to the invention thus form a steam generation unit which continuously supplies steam with a substantially constant steam pressure and/or substantially constant steam quantity to the soleplate throughout the entire ironing process.
  • the steam ironing device according to the invention can be freely selected in terms of type, mode of operation, material and dimensioning within wide, suitable limits.
  • An advantageous development of the steam ironing device provides that at least one of the steam generators, preferably all of the steam generators of the plurality of steam generators, has a steam reservoir for temporarily storing steam generated in the steam generator, with the steam generated in this steam generator being able to be released from the steam reservoir to the soleplate .
  • the process of steam generation by the plurality of steam generators in the steam ironing device according to the invention is additionally improved since the steam accumulator compensates for technically unavoidable fluctuations in the steam generation in the corresponding steam generator. This applies in particular to the preferred embodiment of this development.
  • a further advantageous development of the steam ironing device provides that in at least one of the steam generators, preferably in all steam generators of the plurality of steam generators, a predetermined steam pressure can be built up by means of the steam generation, with this steam generator being controlled in such a way by the controller it can be controlled that the steam with the aforementioned steam pressure can be released from this steam generator to the soleplate.
  • a predetermined steam pressure can be built up by means of the steam generation, with this steam generator being controlled in such a way by the controller it can be controlled that the steam with the aforementioned steam pressure can be released from this steam generator to the soleplate.
  • each steam generator of the plurality of steam generators can be controlled by the controller in such a way that by means of the plurality of steam generators steam of a predetermined and essentially constant steam quantity and/or a predetermined and substantially constant vapor pressure and/or a predetermined and substantially constant temperature and/or a predetermined and substantially constant saturation.
  • the quality of the exposure of the item to be ironed to steam is further improved, since at least one essential parameter for the steam during the ironing process can be kept essentially constant at a predetermined level.
  • the more of the aforementioned parameters are used in the aforementioned manner when controlling the plurality of steam generators, the higher the quality of the supply of steam to the item to be ironed. Accordingly, it is possible to supply perfectly matched steam to the item to be ironed during the entire ironing process, so that a good and reproducible ironing result can be achieved after only a short treatment time.
  • each steam generator of the plurality of steam generators is controlled by the controller in such a way that steam of a predetermined and essentially constant steam quantity and/or a predetermined steam quantity is applied to the soleplate by means of the plurality of steam generators and substantially constant vapor pressure and/or predetermined and substantially constant temperature and/or predetermined and substantially constant saturation.
  • An advantageous development of the aforementioned embodiment of the steam ironing device according to the invention provides that the amount of steam and / or the steam pressure and / or the temperature and / or the saturation of the plurality of steam generators to the
  • the water vapor emitted by the soleplate can be adjusted manually in advance by means of a control unit of the steam ironing device on the steam ironing device and/or by means of at least one sensor unit of the steam ironing device.
  • This enables the aforementioned parameters of the water vapor to be adapted to the conditions of the individual case, ie to the nature of the item to be ironed with the steam ironing device according to the invention.
  • the aforementioned use of sensor technology enables this adjustment of the parameters of the water vapor to be largely automated, so that the operating comfort for the user is also significantly increased.
  • the steam ironing device 2 is designed as a steam ironing station for the household and comprises a water reservoir 4 for storing water 6, two steam generators 8, 10 connected to the water reservoir 4 in a flow-conducting manner for generating steam 12, a soleplate 14 connected to the steam generators 8, 10 in a flow-conducting manner an iron 16 of the steam ironing device 2 for treating an item 18 to be ironed, the soleplate 14 having a plurality of steam outlet openings 20 for applying the steam 12 to the item 18 .
