Definitions

  • the invention relates to a method for mangling laundry items according to the preamble of claim 1.
  • Trough mangles for commercial laundries have heatable mangle troughs.
  • the efficiency of the trough mangles is significantly influenced by the amount of energy available for heating the mangle troughs.
  • Defective troughs for trough mangles of the type discussed here are usually heated by steam or a liquid heat transfer medium.
  • steam the energy released for condensing is used to heat up the deficiency pits.
  • the condensation temperature of steam at the usual maximum pressure of 16 bar is only about 200 ° C. Thus, the per unit time possible energy supply to the lack of wells is limited.
  • liquid heat transfer media in particular oil
  • Such high temperatures can be used only with still wet laundry.
  • damage namely a scorching
  • lower temperatures In the course of the shortage of lack of drainage decreasing moisture content of the laundry must be used to avoid damage, namely a scorching, with lower temperatures. Therefore, in practice, for safety's sake with lower Temperatures worked as possible to avoid burning (singeing) of the laundry items. But this suffers the performance of well-known trough mangles.
  • a trough deficiency is known with a gutter formed by two trough halves.
  • the trough halves are connected in series with regard to their supply with a heating medium.
  • a concrete heating medium, by which the trough halves are heated successively, is not disclosed in the cited document.
  • the script also receives no indication as to how to avoid scorching of the laundry at a maximum deficiency.
  • the invention is based on the object to provide a method for smoothing laundry, whereby it is possible to achieve a maximum deficiency without the risk of damaging the laundry items to be smoothed.
  • a method for achieving this object comprises the measures of claim 1. Accordingly, it is intended to selectively heat each mangle trough so that the heat transfer medium at the end of at least one mangle trough about a predetermined temperature. It can then be specifically heated the respective lack well.
  • the temperature at the beginning of the subsequent lacking well is not above the starting temperature of the preceding lacking well, whereby burns of the items of laundry are avoided.
  • the desired value of the temperature preferably of the heat transfer medium at the end of the or each lack well can be set to a maximum possible setpoint, because it is known what residual moisture the laundry will have at the end of the respective mangle trough.
  • the temperature at the beginning of the respective lack well in particular the inlet temperature of the heat transfer medium into the respective lack well, depending on the temperature at the end of the previous lack well, in particular the outlet temperature of the heat transfer medium from the respective previous mangle trough , is determined.
  • the temperatures are controlled or regulated so that they are in a specific, predetermined ratio to each other.
  • the determination of the inlet temperature of the heat transfer medium based on the outlet temperature of the heat transfer medium of the previous lack of wells is ensured that there is no overheating and thus the risk of scorching the garments in the transfer of laundry from the one mangle trough to the subsequent mangle trough, especially at the beginning of the subsequent mangle trough.
  • the ratio between the outlet temperature of a previous mangle trough inlet temperatures of the subsequent mangle trough is determined so that the fed into the respective mangle trough heat transfer medium has such a high inlet temperature at which a burning of the laundry items at the beginning of the subsequent mangle trough is not yet expected.
  • the temperature at the beginning of the second and any subsequent lack well is about equal to the temperature, in particular of the heat transfer medium at the end of the previous mangle trough.
  • the laundry is exposed at the beginning of a Mangelmulde a temperature which is lower than the temperature at the end of the previous Mangelmulde, preferably approximately equal to the temperature at the end of the previous Mangelmulde, so that a continuous temperature profile from mangle to mangle is guaranteed.
  • this avoids the risk that at the beginning of a mangle trough the laundry items are exposed to a higher temperature than at the end of the previous lack trough, which could result in the risk of damage to the laundry items.
  • a further preferred embodiment of the method provides to measure the outlet temperature of the heat transfer medium to at least some mangle troughs.
  • the inlet temperature of the heat transfer medium is influenced in the subsequent mangle trough, in particular controlled or regulated. This influence is such that the outlet temperature has a certain ratio to the inlet temperature of the heat transfer medium, wherein preferably the temperatures are controlled or regulated so that they are about the same.
  • the measurement of the exit temperature of the heat transfer medium can be used primarily to influence the energy supply to the respective mangle trough.
  • the input temperature of the heat transfer medium in the second and any subsequent lack of wells is brought to the setpoint of the output temperature of the heat transfer medium from the respective previous mangle trough or maintained at the desired value of the output temperature, by preferably a corresponding control. Consequently, the initial temperature of the previous mangle trough is the reference variable for the inlet temperature for the subsequent mangle trough.
  • the heat transfer medium of the subsequent mangle trough can thus be selectively heated to a maximum of the outlet temperature of the laundry from the previous mangle trough.
  • the subsequent lack well is thus heated as far as possible on its inlet side. This ensures a maximum possible shortage.
  • the method is provided to heat the heat transfer medium for each lack well, if necessary, and to lead in a cycle.
  • the heating circuit makes it possible to supply the respective lacking well the energy required to reach the predetermined outlet temperature of the heat transfer medium.
  • the heat transfer medium is circulated as needed.
  • the heat transfer medium leaving the mangle trough returns to the beginning of the same mangle trough without reheating, or the heated heat transfer medium bypasses the mangle trough and is also circulated. It can be targeted by the targeted supply of heated heat transfer medium, the output temperature of each mangle trough set to the desired setpoint, in particular by a corresponding regulation.
  • circulated and cooled heat transfer medium is mixed and introduced such a mixture with a temperature setting in the respective mangle trough.
  • a relatively accurate control of the desired outlet temperature of the heat transfer medium from the mangle trough is possible, with small deviations.
  • An advantageous further development possibility of the method provides to use the exhaust air of the or each heater and / or the exhaust air of the trough deficiency for preheating the lack of supply air.
  • part of the residual energy contained in the exhaust air and / or in the exhaust gas can be used to preheat the lack supply air. Consequently, the deficiency supply only needs relatively little in the shortage of troughs to be heated, whereby the lack of wells few energy is removed for heating the Mangelzu poverty and therefore more energy for actual drying and smoothing of the laundry is available.
  • the exhaust gas of the or each heater is used to preheat the lack supply air. Since the exhaust gas of the heater has a higher temperature than the air of the trough deficiency, can be done with the exhaust of the respective heater particularly effective preheating the lack of supply air without the circulation of a large volume thereof.
