Definitions

  • the invention relates to a method for the wet treatment of laundry according to the preamble of claims 1 and 7.
  • washing machines In the wet treatment of laundry of all kinds different washing machines are used in commercial laundries. These are on the one hand continuous washing machines with several successive chambers in a single rotationally driven drum. In the continuous washing machine, the laundry is at least washed by a pre-wash and a clear wash. However, the continuous washing machine can also be used for washing and rinsing and optionally also for aftertreatment, for example equipping, the laundry. On the other hand, so-called washer-extractors are used in commercial laundries, in which the laundry is washed, rinsed and spun in a drum which has only one chamber and can be driven in rotation.
  • the washing is carried out with a treatment liquid which is heated at least for clear washing, wherein the laundry to be washed is brought to the temperature of the treatment liquid.
  • the treatment liquid is heated with steam. This requires in the laundry a steam generator, which causes high investment costs.
  • the invention is based on the object to provide methods for wet treatment of laundry, which allow heating of the treatment liquid with simple means or an economical operation.
  • a method for achieving this object comprises the measures of claim 1. Accordingly, it is provided to heat the treatment liquid from at least one heating device. This eliminates the need for steam to heat the treatment liquid. On a complex generation of steam in the laundry can be dispensed with by the inventive method.
  • the heating device is preferably a heating device operated with fossil fuels, in particular gas or oil.
  • a heater only requires a gas and / or oil burner, which continuously heats the treatment liquid passed through heating coils in the burner according to the heat exchanger principle.
  • Such a heater is very simple. Above all, such a heating device can alternatively or additionally be used for parallel operation for other purposes.
  • the heating device is a continuous flow heater which continuously heats the treatment liquid pumped in circulation by the heating device. The heated by the heater treatment liquid can then be recycled through the washing machine. It is thus carried out by a continuous pumping of the heated by the heater and when passing through the washing machine and also when warming the laundry cooled treatment liquid.
  • treatment liquid heated by the heating device is circulated through at least one chamber of the continuous washing machine.
  • Such a circuit can be easily realized and leads to the continuous increase in the temperature of the treatment liquid and the laundry, through which the treatment liquid is circulated.
  • the method is provided to operate the heater continuously, ie substantially continuously.
  • the heating energy required is controlled by the amount of gas or oil supplied per unit time of the heater.
  • the heater is essentially constantly operated, namely fired with oil or gas. Only in the case of unforeseen longer interruptions in operation or in the event of a prolonged interruption of the washing process, the heating device is switched off.
  • the invention proposes to use energy which is not required for heating the treatment liquid for washing the laundry in the drum, for other purposes, during the continuous operation of the heating device but currently for heating the washing liquid.
  • the heater may then continue to operate, although presently, treatment liquid for washing the laundry is not to be heated. It is thus maintained the operation of the heater, even if temporary treatment liquid for washing the laundry does not have to be heated.
  • the energy then still generated by the heater is preferably used to heat or heat for other purposes or later required treatment liquid.
  • Another method for solving the above-mentioned object comprises the measures of claim 7. Accordingly, it is provided that treatment liquid for the laundry to be washed in the drum or for other purposes is heated alternately by the at least one heating device.
  • the at least one heating device can thereby be operated continuously over longer periods of time, for which purpose only the heating power is adjusted to adapt to the current needs.
  • this method is suitable for gas and / or oil-fired heating devices that heat or heat the treatment liquid according to the heat exchanger principle. The economics of such heaters is improved if they are operated over a long period of time, preferably with no or as few interruptions as possible.
  • treatment liquid for washing the items of laundry in the drum is primarily heated by the at least one heating device. Only when the treatment liquid and the laundry have reached the intended temperature and further heating of the treatment liquid for washing the respective item of laundry is no longer necessary, during further operation of the at least one heater in at least one storage tank cached liquid, in particular treatment liquid, heated.
  • the at least one storage tank thus serves to buffer the heat energy still generated by the heating device between washing operations of successive batches or items of the laundry.
  • the at least one heating device can continue to operate, possibly with reduced or minimum heating power.
  • the at least one heating device needs according to the invention between the heating of the treatment liquid for successive Laundry items not to be turned off. Uneconomic interruptions in operation of the at least one heating device can be reduced to a minimum.
  • the heated liquid or treatment liquid in the at least one storage tank for flooding the laundry in the drum and / or for providing the preheated treatment liquid for washing the next Wäschepostens.
  • This treatment liquid then only needs to be heated slightly, which reduces the cycle time of the washing machine.
  • the invention can be used particularly advantageously for heating treatment liquid which serves for clear washing of the laundry, namely clear wash liquid.
  • the warming up or heating of the final wash liquid to the temperature required for the final wash by at least one gas and / or oil-fired heating device has proven to be particularly economical.
  • the figures show various washing machines for commercial laundries, with which the inventive method is feasible.
  • the invention is not limited to the washing machines shown.
