Definitions

  • the invention relates to a method for drying laundry according to the preamble of claim 1 and a dryer according to the preamble of claim 5.
  • Dryers for commercial laundries have at least one burner, preferably a gas burner, for heating air used for drying.
  • the air heated by the burner is passed through a drum containing the laundry to be dried, preferably drivable in rotation.
  • the air absorbs moisture from the laundry to be dried.
  • the moist air is then passed into the open air as exhaust air and / or fed back to the at least one burner as circulating air and heated again by it.
  • the air leaving the drum contains most of the moisture. This air cannot, or only to a small extent, be reused as circulating air. It must therefore at least for the most part be led out of the dryer. At the beginning of the drying process, therefore, only a small amount of circulating air is used. A lot of fresh air is then fed to the dryer, at least for the most part via the burner. The at least one burner gets enough combustion air through this large proportion of fresh air. At the end of the drying process, the drum only leaves the air with little moisture. Then a relatively large amount of circulating air and only a little fresh air are supplied to the burner. The at least one burner then contains very little fresh air or no fresh air at all. The burner then works uneconomically. In many cases, imperfect combustion with undesirable soot formation can occur.
  • a dryer for drying laundry which has a rotating drivable drum for receiving the laundry to be dried and a Burner features. Air heated by the burner is passed through the drum to dry the laundry. Air used in drying is circulated through the dryer. If necessary, fresh air is supplied by transporting the fresh air to the burner.
  • a method for solving this problem has the measures of claim 1. Accordingly, the fresh air is transported to the at least one burner during at least part of the drying process. By actively transporting the fresh air to the burner, the fresh air is quasi blown or pressed into the burner. The burner is kind of charged with fresh air. The fresh air is only transported to the burner in a drying phase in which a predominant part of the circulating air is returned to the burner. This is based on the knowledge that at the beginning of the drying process, in which less circulating air is used due to the relatively high moisture content of the air used for drying, the at least one burner itself can suck in enough fresh air.
  • An advantageous development of the method provides for the fresh air to be fed to the burner by at least one fan or blower.
  • This type of transport of fresh air to at least one burner is the simplest and most effective way of charging the burner.
  • the fan speed By setting the fan speed the amount of fresh air supplied to the respective burner can be adjusted or controlled according to requirements, so that the respective burner receives as much fresh air as it needs due to the respective proportion of the circulating air.
  • the burner can thus receive the amount of fresh air required for optimal operation of the same in each drying phase, the amount of fresh air being able to be increased, the greater the proportion of the circulating air returned to at least one burner.
  • a further advantageous embodiment of the method provides, if necessary, also to supply fresh air behind the respective burner to the circulating air heated by the same. This happens before the heated circulating air has reached the laundry to be dried. In this way, the respective burner only needs to be supplied with such an amount of fresh air as is necessary for optimal operation of the same. Any additional fresh air required can be fed directly into the heated circulating air. This also leads to more economical drying.
  • the air flow generator is advantageously assigned to a supply line for fresh air to the respective burner or to a common supply line for all burners.
  • the fresh air can be transported directly through the at least one air flow generator in the at least one feed line to the or each burner.
  • a preferred development of the invention provides for a preferably variable and / or closable feed opening for fresh air that can be admixed with the air heated by the burner to be arranged behind the at least one burner.
  • At least one fan or at least one blower for generating a circulating air flow and / or a closable or variable exhaust air outlet are provided for at least part of the circulating air.
  • the at least one fan can generate a targeted circulating air flow, in particular a circulating air flow with a desired flow rate and / or a desired circulating air flow.
  • the closable or variable exhaust air outlet is used to regulate the proportion of the circulating air that is returned to the at least one burner and is fed back from this after the laundry has been heated. That part of the moist air that is not used as circulating air can be diverted into the open air to remove the moisture that occurs when the laundry is dried in the dryer.
  • the dryer shown schematically in the figures is used for the highly effective and energy-efficient drying of laundry. Such a dryer is mainly used in commercial laundries. In the dryer shown here, air for drying the laundry is heated by a single burner 10.
  • the dryer can, however, also have several burners 10 arranged in parallel or in series.
  • the burner 10 can be either a gas burner or an oil burner.
  • the dryer has an outer housing 11, preferably a closed, box-like housing 11, in which one rotates about a horizontal axis of rotation 12 drivable drum 13, said burner 10, a circulating air fan 14 and below the explained air ducts are arranged.
  • the rotating drivable drum 13 is used to receive the laundry to be dried. It has a loading and unloading opening, not shown.
  • the jacket 15 of the cylindrical drum 13 is made air-permeable so that air used for drying can flow through the drum 13 and the initially moist laundry located therein.
  • the drum 13 is rotatably mounted in a lower compartment 16 of the housing 11.
  • the drum 13 is partially surrounded by air-impermeable arcuate walls 17 and 18 at a small distance from the cylindrical jacket 15.
  • the walls 17 and 18 lie on a concentric circular path around the axis of rotation 12, whereby the air-impermeable walls 17 and 18 surround the cylindrical shell 15 of the drum 13 at a small distance to form a narrow gap 19 between the shell 15 of the drum 13 and the walls 17 and 18.
  • Each of the preferably equally large walls 17 and 18 extends over approximately 120 ° to 150 °, preferably approximately 135 °, of the circumference of the drum 13.
  • the circulating air fan 14 is located in the upper compartment 22 of the housing 11 at a distance from the outer wall 27, which may also be another air flow generator, for example a blower.
  • the burner 10 is arranged approximately in the middle in the upper compartment 22 in such a way that a schematically indicated elongated flame tube 28 for generating several adjacent flames runs parallel to the axis of rotation 12.
  • the axes of the flames run horizontally, specifically transversely to the axis of rotation 12.
  • the burner 10 can also be designed in such a way that it generates only a single horizontal flame which extends transversely to the axis of rotation 12.
  • the burner 10 is enclosed in the upper compartment 22.
  • a rear wall 29 is assigned to the burner 10 on the rear side.
  • Parallel, free edges 32 of the air guide walls 30 and 31 form a preferably elongated, vertical air outlet opening 33 of the housing 11 surrounding the burner 10 from the rear wall 29 and the air guide walls 30 and 31.
  • the air outlet opening 33 which is essentially open over the entire surface, thus forms a slot opening or slot nozzle.
  • the air outlet opening 33 is spaced apart from an outer wall 34 of the housing 11 opposite the outer wall 27 of the housing 11.
  • the upper air ducting wall 30 is also spaced apart from an upper cover wall 35 of the housing 11 of the dryer. Accordingly, the rear wall 29, which extends only up to the upper air guide wall 30, also ends at a distance below the top wall 35 of the housing 11.
  • a circulating air flap 37 is provided in the interior of the upper compartment 22.
  • the circulating air flap 37 can be pivoted about a horizontal pivot axis 38, preferably by a drive (not shown).
  • the circulating air flap 37 can be pivoted so far that on the one hand it completely closes the exhaust air connection 36 in an open position and on the other hand, in a closed position, it extends the free edge 32 of the air duct wall 30 above the burner 10 to the outer wall 34 and thereby seals it. Any intermediate positions of the circulating air flap 37 are possible between the mentioned extreme positions.
  • the above-described design of the housing 11, in particular the lower compartment 16 and the upper compartment 22, allows a targeted air flow to be brought about in the dryer.
  • the air outlet opening 21 opens into a backflow space 39 closed off by the wall 18, the transverse wall 25, the wall 26 and the outer wall 27.
  • the backflow space 39 in the lower compartment 16 is connected to a through an opening in the partition 23, not shown in the figures Backflow space 40 in the upper compartment 22.
  • This backflow space 40 is delimited by the partition 23, the top wall 35, an upper part of the outer wall 27, the rear wall 29 behind the burner 10 and the air ducting wall 30 above the burner 10, which is spaced from the top wall 35.
  • an inflow space 41 is formed between the upper part of the outer wall 34 and the air outlet opening 33 spaced therefrom, the space surrounding the burner 10 between the air guide walls 30 and 31, the transverse walls 24, 25 and the air inlet opening 20 in the Drum 13, an inflow space 41 is formed.
  • the upper compartment 22 and the lower compartment 16 are also connected to one another via the inflow space 41 through a corresponding opening in the partition 23.
  • the return flow space 40 and the inflow space 41 can be separated from one another.
  • a partial connection of the return flow space 40 with the inflow space 41 and a partial release of the exhaust air connection 36 can be set.
  • the burner 10 is assigned an air flow generator.
  • This is in the Fig. 3 represented symbolically.
  • This embodiment is an air flow generator designed as a fan 42.
  • the air flow generator can also be formed by a plurality of fans 42.
  • the fan 42 sucks in fresh air outside the housing 11 of the dryer through a suction opening (not shown) and transports it to the burner 10, preferably into the burner 10.
  • the lateral arrangement of the fan 42 next to the housing 11 is supply air or fresh air from the fan in the direction transported or blown into the housing 11 parallel to the axis of rotation of the drum 13.
  • the fresh air transported into the housing by the fan 42 reaches the interior of the burner 10, for which purpose it flows through the housing surrounding the burner 10.
  • the fresh air can be transported through the elongated flame tube 28, specifically preferably together with the gas to be burned by the burner 10. It is also conceivable, however, to feed the supply air or fresh air transported by the fan 42 into the interior of the burner 10 outside the flame tube 28 or around the burner 10.
  • the fan 42 can be driven by an electric motor 43, for example.
  • the speed of the electric motor 43 can preferably be changed or controlled or regulated.
  • the throughput of fresh air or supply air through the fan 42 can be changed and thus adapted to requirements.
  • a desired flow of fresh air can thereby be transported to the burner 10.
  • a fresh air connector which is arranged in a wall of the housing 11 and is not shown in the figures opens into the inflow space 41 behind the air outlet opening 33 between the air guide walls 30 and 31, seen in the flow direction.
  • the opening of the fresh air connection is preferably variable in cross section. It is also conceivable that the fresh air connection can be completely shut off. Additional fresh air can be supplied to the inflow space 41 via the fresh air connection behind the burner 10 and / or outside the burner 10 in the flow direction. The amount of fresh air is variable by changing the cross section of the fresh air connection.
  • the fresh air supply via the fresh air connection can also be completely interrupted.
  • the drying process begins with the supply of air 44 heated by the burner 10 through the inflow space 41 and the air inlet opening 20 to the rotatably driven drum 13, in which the laundry to be dried is located.
  • the air 44 flows along the laundry that is initially very damp, the air absorbs a great deal of moisture.
  • relatively moist air 45 leaves the drum 13 through the air outlet opening 21.
  • the moist air 45 flows through the return flow space 39 in the lower part 16 into the return flow space 40 in the upper compartment 22, where it is transported on by the circulating air fan 14.
  • the moist air 45 which contains a high proportion of moisture at the beginning of the drying process, is initially discharged completely or for the most part with the circulating air flap 37 completely or almost completely closed through the exhaust air nozzle 36 from the housing 11 of the dryer as exhaust air 46.
  • Fresh air is supplied to the dryer from outside as a replacement for the exhaust air 46 removed. This takes place mainly through the burner 11, where the fresh air supplied from the outside serves as combustion air. This fresh air is initially drawn in automatically by the burner 10.
  • it can also be provided in this drying stage to transport fresh air to the burner 10 by the fan 42. Additionally or alternatively, further fresh air can be fed directly to the inflow space 41 downstream of the burner 10, if required.
  • the moisture content in the moist air 45 decreases.
  • Part of the moist air 45 is then fed as circulating air past the burner 10 and / or through the burner 10 to the drum 13 with the laundry to be dried.
  • the circulating air flap 37 is partially opened by pivoting it clockwise (based on the illustration in FIG Fig. 2 ) around the pivot axis 38.
  • the circulating air flap 37 is opened so far that the desired circulating air flow is established, i.e. a specific portion of the moist air 45 is fed back to the drum 13 as circulating air 47 and the remaining portion of the moist air 45 through the exhaust air connection 36 is passed as exhaust air 46 into the open.
  • Circulating air 47 is used in dryers, especially those for commercial laundries, in order to reuse the thermal energy in the moist air 45 and not have to reheat so much cold fresh air. For this reason, the proportion of circulating air 47 is successively increased as the drying time increases. To this end, the circulating air flap 37 is gradually opened further so that it closes the exhaust air nozzle 36 more and more and moist air 45 containing little residual heat escapes through the exhaust air nozzle 36 into the open air.
  • the moist air 45 used as circulating air 47 can be wholly or partly passed through the burner 10 with the fresh air transported by the fan 45 to the burner 10. If the humid air 45 used as circulating air is only partially passed through the burner 10, part of the humid air 45 is also passed as circulating air past the burner 10 in order to be in front of the air outlet opening 33 with the air 44 and / or heated by the burner 10 To unite circulating air, so that the circulating air 47 and the from Burner 10 heated, also formed from circulating air 47, heated air 44 can be fed back through the inflow space 41 to the drum 13 of the laundry as a whole.
  • the quantity of the fresh air transported from the fan 42 to the burner 10 and through it can be changed by controlling the speed of the fan 42 accordingly. This makes it possible to change both the fresh air flow to and through the burner 10 and the pressure of the fresh air . In this way, the burner 10 can be charged or inflated to a greater or lesser extent, depending on the proportion of the circulating air 47.
  • the fan 42 can be completely switched off at the beginning of the drying process when working with little circulating air 47, so that the burner 10 then automatically draws in the necessary fresh air. Only when the proportion of circulating air increases, in particular predominantly or only circulating air 47 is used, the fan 42 is started up, so that fresh air is then preferably transported under pressure to the burner 10 or blown into the burner 10, the pressure and / or the amount of fresh air that is transported by the fan 42 to the burner 10 increases continuously with the increase in the proportion of the circulating air 47. In the event that the dryer is operated only with circulating air 47, the fresh air flow and / or the pressure of the fresh air reach a maximum through corresponding operation of the fan 42.
