Description

Die Erfindung betrifft eine Heißmuldenmangel, insbesondere Mehrmuldenmangel zum Trocknen und Glätten feuchter Wäschestücke.The invention relates to a hot-tub shortage, in particular a multi-well shortage for drying and smoothing damp laundry items.

Es ist bekannt, bei Heißmuldenmangeln das sich beim Mangeln von Wäschestücken in den Arbeitszonen zwischen den Mangelzylindern und den Mangelmulden bildende Wasserdampf-Luft-Gemisch als Abluft abzusaugen. Dazu besitzt zumeist der Mangelzylinder eine perforierte Mantelfläche und einen hohlen Lagerzapfen, der an eine Abzugseinrichtung angeschlossen ist (DE-PS 131 918).It is known to suck off the water vapor-air mixture which forms when ironing laundry items in the working zones between the ironing cylinders and the ironing ironers as exhaust air. For this purpose, the shortage cylinder mostly has a perforated outer surface and a hollow bearing journal which is connected to a trigger device (DE-PS 131 918).

Diese Abluft beinhaltet eine erhebliche ungenutzte Wärmemenge, die kontinuierlich vom Beheizungssystem der Heißmuldenmangel aufgebracht werden muß.This exhaust air contains a considerable amount of unused heat, which must be continuously applied by the heating system due to the lack of hot troughs.

Es ist deshalb bereits eine Heißmuldenmangel bekannt geworden, an welcher zumindest ein Teil dieser Abwärme nachgenutzt wird (DE-PS 468 074). Bei dieser Mangel führt die an den Mangelzylinder angeschlossene Absaugleitung über einen Ventilator zu einem Durchgang eines Wärmeübertragers, welcher geeignet ist, die Wärme eines Luftstromes an einen anderen zu übertragen. Dazu besitzt der Wärmeübertrager einen zweiten Durchgang, durch welchen mittels eines weiteren Ventilators aus der Umgebung der Heißmuldennangel angesaugte Frischluft gedrückt wird. Die auf diese Weise erwärmte'Frischluft wird zwei Kästen zugeführt, die vor bzw. hinter der Mangelmulde angeordnet sind und siebartig durchbrochene Stellen zum Austritt der Frischluft besitzen. Die Frischluft soll im Bereich dieser Kästen ihre Wärme an die vorbeiwandernde Wäsche abgeben und diese vor- bzw. nachtrocknen.A shortage of hot troughs has therefore already become known, in which at least some of this waste heat is reused (DE-PS 468 074). In the case of this defect, the suction line connected to the defect cylinder leads via a fan to a passage of a heat exchanger which is suitable for transferring the heat of an air stream to another. For this purpose, the heat exchanger has a second passage, through which another fan from the vicinity of the hot plates is used fresh air is sucked in. The fresh air heated in this way is supplied to two boxes which are arranged in front of or behind the trough and have perforated areas for the fresh air to escape. In the area of these boxes, the fresh air should give off its heat to the laundry passing by and pre-dry or post-dry it.

Nachteilig dabei ist, daß der Wärmeübertrager getrennt von der Mangel und in größerer Distanz von dieser angeordnet ist. Damit sind entweder bereits große Wärmeverluste bei der Überführung der Abluft vom Mangelzylinder zum Wärmeübertrager bzw. großer Aufwand für die Wärmeisolierung der entsprechenden Leitungen verbunden. Hinzu kommen ohnehin großer Platzbedarf und Bauaufwand. Die nach dem Kontakt mit der zu trocknenden Wäsche in die Mangelumgebung strömende Warmluft bedeutet weiterhin eine nicht zu akzeptierende Belastung des Bedienpersonals der Heißmuldenmangel. Außerdem geht auf diese Weise dem System die immer noch beträchtliche in der Frischluft enthaltene Wärmemenge endgültig verloren.The disadvantage here is that the heat exchanger is arranged separately from the ironer and at a greater distance from it. This is associated either with large heat losses during the transfer of the exhaust air from the shortage cylinder to the heat exchanger or with great expense for the heat insulation of the corresponding lines. In addition, there is a lot of space and construction work anyway. The warm air flowing into the shortage environment after contact with the laundry to be dried also means an unacceptable burden on the operating personnel due to the shortage of hot troughs. The system also permanently loses the amount of heat still present in the fresh air.

Mit der DE-OS 28 14 618 ist weiterhin eine Bügelanlage bekannt geworden, bei welcher die in einem Wärmeübertrager durch die Abluft aus den Mangelzylindern und das beim Beheizen der Mangelmulden anfallende Kondensat erwärmte Frischluft unmittelbar in der Nähe einer Walzen-Mulden-Einheit (Mangeleinheit) dem Mangelraum zugeführt wird. Diese Bügelanlage hat jedoch ebenfalls den Nachteil einer externen Anordnung des Wärmeübertragers mit allen bereits beschriebenen Folgen aufzuweisen.With DE-OS 28 14 618 an ironing system has also become known, in which the fresh air heated in a heat exchanger by the exhaust air from the shortage cylinders and the condensate produced when the shortage troughs are heated are in the immediate vicinity of a roller-trough unit (shortage unit). the shortage area is fed. However, this ironing system also has the disadvantage of an external arrangement of the heat exchanger with all the consequences already described.

Darüber hinaus ist es bei Heißmuldenmangeln üblich, bei Bedarf die Leistung einer Mangel mit verhältnismäßig wenig Aufwand durch Nachrüsten mit weiteren Mangeleinheiten zu erhöhen. Das ist bei der Bügelanlage gemäß der DE-OS 28 14 618 nicht möglich.In addition, in the case of hot trough defects, it is customary, if necessary, to perform the defect with relatively little effort by retrofitting with additional defect units increase. This is not possible with the ironing system according to DE-OS 28 14 618.

Es ist Zweck der Erfindung, unter Vermeidung von Umweltbelastungen Energieverluste der Heißmuldenmangel zu verringern.The purpose of the invention is to reduce energy losses due to the lack of hot troughs while avoiding environmental pollution.

Der Erfindung liegt die Aufgabe zugrunde, eine Heißmuldenmangel zu schaffen, welche eine intensivere Ausnutzung der in der Abluft enthaltenen Wärme gestattet, wobei das dazu notwendige Wärmerückgewinnungssystem platzsparend im Inneren der Heißmuldenmangel angeordnet sein und ohne weiteres deren nachträgliche Erweiterung um zusätzliche Mangeleinheiten zulassen soll.The invention has for its object to provide a hot tub shortage, which allows a more intensive use of the heat contained in the exhaust air, the heat recovery system required for this purpose should be arranged in a space-saving manner inside the hot tub shortage and should easily allow its subsequent expansion by additional shortage units.

Die Lösung dieser Aufgabe enthält der kennzeichnende Teil des ersten Patentanspruches. Weitere Ausgestaltungsmöglichkeiten der erfindungsgemäßen Heißmuldenmangel sind den Patentansprüchen 2 bis 8 zu entnehmen.The solution to this problem is contained in the characterizing part of the first claim. Further design options for the hotplate shortage according to the invention can be found in patent claims 2 to 8.

Ein sehr wesentlicher Vorteil der erfindungsgemäßen Heiß- 'muldenmangel besteht in der unmittelbaren Zuordnung eines Wärmeübertragers zu jeder Mangeleinheit. Dadurch wird der Wärmeübertrager bereits kurz nach dem Austritt der Abluft aus dem Mangelzylinder von dieser durchströmt. Die Wärmeverluste sind dementsprechend gering, Leitungen mit hohem Isolationsaufwand entfallen fast völlig.A very important advantage of the hot-plate ironer according to the invention is the direct assignment of a heat exchanger to each ironer unit. As a result, the heat exchanger is flowed through shortly after the exhaust air exits the ironing cylinder. The heat losses are accordingly low, and cables with a high level of insulation are almost completely eliminated.

Diese Zuordnung gestattet es weiterhin, in Verwirklichung des Baukastenprinzips jederzeit eine Erweiterung der Heißmuldenmangel um weitere Mangeleinheiten einschließlich des zugehörigen Wärmeübertragers vorzunehmen.This assignment also makes it possible, in the implementation of the modular principle, at any time to expand the hotplate ironer by additional ironing units, including the associated heat exchanger.

Die nach dem Durchströmen der Wärmeübertrager erfolgende Einleitung der Abluft in einen Abluftsammelkanal ermöglicht die Ausstattung der Abzugseinrichtung mit einem einzigen Abluftventilator, der auf sämtliche vorhandenen Mangeleinheiten wirkt.The introduction of the exhaust air into an exhaust air collection duct after the flow through the heat exchangers enables the extraction device to be equipped with a single one Exhaust fan that affects all existing deficiency units.

Im Falle des Vorhandenseins mehrerer Mangeleinheiten (Mehrmuldenmangel) ordnen sich die Strömungsräume der Wärmeübertrager, die für die Frischluft vorgesehen sind, zu einem durchgehenden Frischluftzuführkanal. Die Frischluft wird darin infolge des Passierens mehrerer Wärmeübertrager stufenweise erwärmt.If there are several shortage units (multi-well shortage), the flow spaces of the heat exchangers, which are provided for the fresh air, are arranged in a continuous fresh air supply duct. The fresh air is gradually heated as a result of passing several heat exchangers.

Entnommen wird die Frischluft dem Raum, der von der äußeren Begrenzung der Heißmuldenmangel gebildet wird. Das ist vorzugsweise der Innenraum eines Seitenständers, der bereits eine höhere Temperatur aufweist als die Umgebung der Heißmuldenmangel.The fresh air is taken from the room, which is formed by the outer boundary of the hot tub shortage. This is preferably the interior of a side stand, which is already at a higher temperature than the area surrounding the hotplate shortage.

Zur Vermeidung unnötiger Verschmutzung der Strömungsräume der Wärmeübertrager ist die Ansaugöffnung des Frischluftzuführkanals mit einem Filter versehen, das z. B. Flusen und ähnliches zurückhält.In order to avoid unnecessary contamination of the flow spaces of the heat exchangers, the intake opening of the fresh air supply duct is provided with a filter which, for. B. holds back lint and the like.

Besonders vorteilhaft ist es, wenn zwischen dieser Ansaugöffnung und einer in der äußeren Begrenzung der Heißmuldenmangel angebrachten Eintrittsöffnung für Umgebungsluft der Abluftventilator der Absaugeinrichtung angeordnet ist, dessen Antrieb auf diese Weise wirksam gekühlt wird.It is particularly advantageous if the exhaust air fan of the suction device is arranged between this suction opening and an inlet opening for ambient air, which is provided in the outer boundary of the hot-plate shortage, the drive of which is effectively cooled in this way.

Die von der Luftzuführeinrichtung geförderte und in den Wärmeübertragern erwärmte Frischluft wird einer Ausblaseinrichtung zugeführt, die sich gemeinsam mit den Mangelzylindern und den Mangelmulden in einem nahezu abgeschlossenen Mangelraum befindet. Dieser Mangelraum besitzt lediglich Ein- und Auslaßöffnungen für die zu mangelnden Wäschestücke. Auf diese Weise wird dem Mangelraum trockene, jedoch bereits erhitzte Frischluft zugeführt. Diese besitzt ein hohes Trocknungspotential, ohne daß zusätzliche Energie aufgewendet werden muß.The fresh air conveyed by the air supply device and heated in the heat exchangers is fed to a blow-out device which, together with the shortage cylinders and the shortage troughs, is located in an almost closed shortage space. This lack space has only inlet and outlet openings for the items to be lacking. In this way, dry but already heated fresh air is supplied to the shortage area. This owns a high drying potential without the need for additional energy.

Die Ausblaseinrichtung soll im ersten Drittel des Mangelraumes, also in der Zone mit dem höchsten Wärmebedarf, angeordnet sein.The blow-out device should be arranged in the first third of the shortage area, i.e. in the zone with the highest heat requirement.

Ein besonderer Vorteil kann erzielt werden, wenn die Ausblaseinrichtung als an sich von Spanntrockenmaschinen her bekannter Düsenkasten ausgebildet ist. Dieser kann z. B. vor dem Einlauf in die erste Mangelmulde angeordnet sein und so zu einer wirksamen Trocknung der Wäschestücke beitragen.A particular advantage can be achieved if the blow-out device is designed as a nozzle box known per se from tension drying machines. This can e.g. B. be arranged before entering the first mangle trough and thus contribute to effective drying of the laundry items.

Im nachfolgenden soll die Erfindung anhand eines Ausführungsbeispiels näher erläutert werden.
In den Zeichnungen zeigen:

  • Fig. 2: einen teilweisen Querschnitt gemäß Schnittlinie II - II in Fig. 1.
In the following, the invention will be explained in more detail using an exemplary embodiment.
The drawings show:
  • Fig. 1: a longitudinal section through an inventive hotplate ironer according to section line I - I in Fig. 2 and
  • 2: a partial cross section along section line II - II in Fig. 1st

Eine Heißmuldenmangel, auf die sich die Erfindung bezieht, besteht in ihrem Grundaufbau im wesentlichen aus zwei Seitenständern 1, mindestens einem Mangelzylinder 2, der in den Seitenständern 1 drehbar gelagert ist und mindestens einer Mangelmulde 3. Der Mangelzylinder 2 wird von der Mangelmulde 3 auf einem Zentriwinkel von 120° bis 180° mantelseitig umschlossen. Es sind auch Heißmuldenmangeln bekannt, bei denen jedem Mangelzylinder 2 zwei derartige Mangelmulden 3 zugeordnet sind.A hotplate ironer, to which the invention relates, consists essentially of two side stands 1, at least one ironer cylinder 2, which is rotatably mounted in the side stands 1 and at least one ironer bowl 3. The ironer 2 is from the ironer 3 on one Central angle from 120 ° to 180 ° enclosed on the casing side. There are also hot trough ironers known, in which each ironer cylinder 2 is assigned two such ironer ironers 3.

Im vorliegenden Beispiel bilden jeweils ein Mangelzylinder 2, eine Mangelmulde 3, die ihnen als Gestell zugeordneten Abschnitte der Seitenständer 1 sowie der nicht dargestellte Antrieb eine Mangeleinheit 4. Fig. 1 zeigt demzufolge eine Mehrmuldenmangel mit drei aufeinanderfolgenden Mangeleinheiten 4. Die Mangelmulden 3 werden dabei durch Muldenbrücken 5 verbunden. Obwohl in der gewählten Schnittebene I - I die Mangelzylinder 2, die Mangelmulden 3 und auch die Muldenbrücken 5 nicht erkennbar sind, wurden diese in Fig. 1 zur Verdeutlichung des Aufbaues der Heißmuldenmangel durch Strichlinien angedeutet.In the present example, each form a shortage cylinder 2, a mangle trough 3, the sections of the side stand 1 assigned to them as a frame and the drive (not shown) a mangle unit 4. FIG. 1 consequently shows a multi-hull mangle with three successive mangle units 4. The mangle troughs 3 are connected by trough bridges 5. Although in the selected sectional plane I - I the shortage cylinders 2, the shortage troughs 3 and also the trough bridges 5 are not recognizable, these have been indicated in FIG. 1 by means of dashed lines to clarify the structure of the hot trough shortage.

Sowohl die Mangelmulden 3 als auch die Muldenbrücken 5 sind beheizt. Sie besitzen dafür Heizelemente, die zumeist von einem strömungsfähigen Wärmeträgermedium durchströmt werden. Das kann z. B. Heißdampf oder Wärmeträgeröl sein.Both the mangle troughs 3 and the trough bridges 5 are heated. For this purpose, they have heating elements which are mostly flowed through by a flowable heat transfer medium. That can e.g. B. superheated steam or heat transfer oil.

Sowohl die Heizelemente als auch das System der Heißmuldenmangel zur Versorgung mit dem Wärmeträgermedium wurden in den Zeichnungen, da für den vorliegenden Zusammenhang nicht von unmittelbarer Bedeutung, nicht dargestellt.Both the heating elements and the system for the lack of hot troughs for supplying the heat transfer medium were not shown in the drawings, since they are not of immediate importance for the present context.

Der ersten Mangeleinheit 4 ist eine an sich bekannte Eingabeeinheit 6 vorgeordnet. Die Mangelzylinder 2 sind als Hohlzylinder ausgeführt und besitzen eine perforierte Mantelfläche. Desgleichen ist auch ein Lagerzapfen jedes Mangelzylinders 2 hohl und bildet so eine Absaugöffnung 7, die in einen Luftverteilerkasten 8 mündet.The first deficiency unit 4 is preceded by an input unit 6 known per se. The lack cylinders 2 are designed as hollow cylinders and have a perforated outer surface. Likewise, a bearing pin of each mangle cylinder 2 is hollow and thus forms a suction opening 7 which opens into an air distribution box 8.

Jeder Mangeleinheit 4 ist ein Wärmeübertrager 9 mit zwei Strömungsräumen zugeordnet. Vorzugsweise sind die Wärmeübertrager 9 als Kreuzstrom-Plattenwärmeübertrager ausgebildet, so daß, wie in Fig. 2 zu erkennen ist, ein erster Strömungsraum 30 aus einer Vielzahl von zwischen den-Platten des Wärmeübertragers bestehenden Spalten 10 und ein zweiter Strömungsraum 31 aus einer Vielzahl von Spalten 11 gebildet wird.Each deficiency unit 4 is assigned a heat exchanger 9 with two flow spaces. The heat exchangers 9 are preferably designed as cross-flow plate heat exchangers, so that, as can be seen in FIG. 2, a first flow space 30 consisting of a plurality of columns 10 existing between the plates of the heat exchanger and a second flow space 31 consisting of a plurality of columns 11 is formed.

Möglich im Sinne der Erfindung ist auch, daß die Wärmeübertrager 9 nach dem Gegen- oder Gleichstromprinzip arbeiten. Desgleichen können auch die Wärmeübertragungsflächen anders gestaltet sein, z. B. als Glasrohr-Wärmeübertrager. Vorteilhaft ist auch der Einsatz von Wärmerohren.It is also possible in the sense of the invention that the heat exchangers 9 operate according to the countercurrent or cocurrent principle. Likewise, the heat transfer surfaces can be designed differently, e.g. B. as a glass tube heat exchanger. The use of heat pipes is also advantageous.

Die Wärmeübertrager 9 können auch, wie in Fig. 1 durch eine Strichlinie angedeutet, aus mehreren Wärmeübertrager-Bausteinen zusammengesetzt sein.The heat exchangers 9 can also, as indicated by a broken line in FIG. 1, be composed of a plurality of heat exchanger modules.

Die Spalte 10 eines jeden Wärmeübertragers 9 sind einerseits über den Luftverteilerkasten 8 mit der Absaugöffnung 7 des zugehörigen Mangelzylinders 2 verbunden, andererseits münden sie in einen Abluftsammelkanal 12, der alle vorhandenen Mangeleinheiten 4 mit dem Abluftventilator 13 der Absaugeinrichtung verbindet. An den letzteren schließt sich eine aus dem Mangelaufstellungsraum herausführende Abluftleitung 14 an.The gaps 10 of each heat exchanger 9 are connected on the one hand via the air distribution box 8 to the suction opening 7 of the associated mangle cylinder 2, on the other hand they open into an exhaust air collecting duct 12 which connects all existing mangle units 4 to the exhaust air fan 13 of the suction device. The latter is followed by an exhaust air duct 14 leading out of the ironing room.

Jeder Mangeleinheit 4 ist außerdem eine Abluftmengenregeleinrichtung 15 zugeordnet. Diese kann, wie beispielsweise in Fig. 2, zwischen dem Wärmeübertrager 9 und dem Abluftsammelkanal 12, aber auch zwischen der Absaugöffnung 7 und dem Luftverteilerkasten 8 oder anderswo angeordnet sein.Each deficiency unit 4 is also assigned an exhaust air quantity control device 15. This can, as for example in FIG. 2, be arranged between the heat exchanger 9 and the exhaust air collecting duct 12, but also between the suction opening 7 and the air distribution box 8 or elsewhere.

Erfindungsgemäß bilden die aus den Spalten 11 bestehenden Strömungsräume 31 der Wärmeübertrager 9 einen durchgehenden Frischluftzuführkanal 16, der mit der Luftzuführeinrichtung 17 verbunden ist. Im einfachsten Fall einer Einmuldenmangel mit nur einer Mangeleinheit 4 wird der Frischluftzuführkanal 16 lediglich durch die Spalte 11 des einzigen vorhandenen Wärmeübertragers 9 gebildet.According to the invention, the flow spaces 31 of the heat exchangers 9 consisting of the columns 11 form a continuous fresh air supply duct 16 which is connected to the air supply device 17. In the simplest case of a single-cavity ironer with only one ironer unit 4, the fresh air supply duct 16 is formed only by the gaps 11 of the only available heat exchanger 9.

Eine Ansaugleitung 18 führt vom Frischluftzuführkanal 17 zum Frischluftventilator 19, während eine Druckleitung 20 in einer Ausblaseinrichtung 21 endet. Diese ist im vorliegenden Beispiel besonders vorteilhaft als Düsenkasten ausgebildet, wie er von Spanntrockenmaschinen hinreichend bekannt ist.An intake line 18 leads from the fresh air supply duct 17 to the fresh air fan 19, while a pressure line 20 ends in a blow-out device 21. In the present example, this is particularly advantageously designed as a nozzle box, as is well known from tension drying machines.

Die Ausblaseinrichtung 21 ist im ersten Drittel des von den Seitenständern 1, einer oberen Abdeckung 22, der von den Mangelmulden 3 und den Muldenbrücken 5 gebildeten geschlossenen Fläche sowie einer Vorderwand 23 und einer Rückwand 24 begrenzten, nahezu geschlossenen Mangelraumes 25 angeordnet.The blow-out device 21 is arranged in the first third of the almost closed lack space 25 delimited by the side stands 1, an upper cover 22, the closed surface formed by the lack troughs 3 and the trough bridges 5 and a front wall 23 and a rear wall 24.

Dieses erste Drittel des Mangelraumes 25 ist von den Erfordernissen des Mangelprozesses her der Abschnitt mit dem größten Wärmebedarf. Aus Fig. 1 ist zu entnehmen, daß die Ausblaseinrichtung 21 unmittelbar vor der ersten Mangeleineinheit 4 angeordnet ist.This first third of the shortage space 25 is the section with the greatest heat requirement in terms of the shortage process requirements. From Fig. 1 it can be seen that the blow-out device 21 is arranged immediately before the first ironing unit 4.

Die Ausblaseinrichtung 21 kann ebenso am Ende der ersten Mangeleinheit 4 und der ersten Muldenbrücke 5 angeordnet sein. Die Ansaugöffnung des Frischluftzuführkanals 16 befindet sich erfindungsgemäß innerhalb der äußeren Begrenzung der Heißmuldenmangel, vorzugsweise innerhalb des die Wärmeübertrager 9, die Luftverteilungskästen 8 und den Abluftsammelkanal 12 aufnehmenden Seitenständers 1.The blow-out device 21 can also be arranged at the end of the first mangle unit 4 and the first trough bridge 5. According to the invention, the suction opening of the fresh air supply duct 16 is located within the outer boundary of the hot-plate shortage, preferably within the side stand 1 which receives the heat exchangers 9, the air distribution boxes 8 and the exhaust air collecting duct 12.

Die Ansaugöffnung ist vorteilhafterweise mit einem Filter 26 versehen, welches vor allem Flusen etc. zurückhält.The suction opening is advantageously provided with a filter 26, which mainly retains lint etc.

Die Rückwand 24 besitzt schließlich in der Nähe des Abluftventilators 13 eine Öffnung 27, die den Eintritt von Luft aus der Umgebung der Heißmuldenmangel in den Seitenständer 1 gestattet.Finally, the rear wall 24 has an opening 27 in the vicinity of the exhaust fan 13, which allows air to enter the side stand 1 from the vicinity of the hotplate shortage.

Als besonders wesentliches Merkmal der Erfindung ist zusammenfassend zu bemerken, daß das gesamte vorstehend beschriebene Wärmerückgewinnungssystem einschließlich der Absaug-und der Luftzuführeinrichtung innerhalb der äußeren Begrenzung der Heißmuldenmangel angeordnet ist, d. h., daß außerhalb der Heißmuldenmangel die Anordnung jeglicher zusätzlicher Aggregate zur Verwirklichung einer Wärmerückgewinnung entfällt.As a particularly essential feature of the invention, it should be noted in summary that the entire heat recovery system described above, including the suction and air supply device, is arranged within the outer boundary of the hotplate shortage, i. That is, outside the hot tub shortage, the arrangement of any additional units to achieve heat recovery is eliminated.

Die Wirkungsweise der erfindungsgemäßen Heißmuldenmangel ist folgendermaßen:

  • Die zu mangelnden Wäschestücke werden in bekannter Weise der Eingabeeinheit 6 übergeben und durchlaufen nacheinander die Mangeleinheiten 4 der Heißmuldenmangel.
The mode of operation of the hotplate shortage according to the invention is as follows:
  • The items of laundry to be ironed are transferred to the input unit 6 in a known manner and successively pass through the ironer units 4 of the hotplate ironer.

Infolge des Kontaktes der Wäschestücke mit den beheizten Mangelmulden 5 wird das in ihnen enthaltene Wasser verdampft. Der Wasserdampf tritt durch die Perforation des Mangelzylinders 2 in dessen Innenraum ein und bildet mit der durch die freie Oberseite des Mangelzylinders 2 eindringenden Luft ein Wasserdampf-Luft-Gemisch, die Abluft 28. Durch die Absaugöffnungen 7 tritt die Abluft 28 (durch Volllinienpfeile dargestellt) in die Luftverteilerkästen 8 und danach in die Spalte 10 der Wärmeübertrager 9 ein. Sie erreicht schließlich den Abluftsammelkanal 12 und wird durch den Abluftventilator 13 über die Abluftleitung 14 aus der Heißmuldenmangel abgeführt.As a result of the laundry items coming into contact with the heated mangle troughs 5, the water contained in them is evaporated. The water vapor enters through the perforation of the mangle cylinder 2 into its interior and forms a water vapor-air mixture, the exhaust air 28, with the air entering through the free upper side of the mangle cylinder 2. The exhaust air 28 passes through the suction openings 7 (represented by solid line arrows). into the air distribution boxes 8 and then into the column 10 of the heat exchanger 9. It finally reaches the exhaust air collecting duct 12 and is discharged from the shortage of hot plates by the exhaust air fan 13 via the exhaust air line 14.

Entsprechend den konkreten Arbeitsbedingungen wird die Menge der aus den Mangelzylindern 2 zu fördernden Abluft 28 individuell für jede Mangeleinheit 4 durch die Abluftmengenregeleinrichtung 15 beeinflußt.In accordance with the specific working conditions, the amount of exhaust air 28 to be conveyed from the lack cylinders 2 is individually influenced by the exhaust air quantity control device 15 for each lack unit 4.

Unter der Wirkung des Frischluftventilators 19 der Luftzuführeinrichtung 17 tritt Frischluft 29 (durch Strichlinienpfeile dargestellt) aus dem Innenraum des Seitenständers 1 durch das Filter 26 in den Frischluftzuführkanal 16 ein. Sie wird durch Luft aus der Umgebung der Heißmuldenmangel ersetzt, die durch die Öffnung 27 in den Seitenständer 1 eintritt und dabei den Antrieb des Abluftventilators 13 wirksam kühlt.Under the action of the fresh air fan 19 of the air supply device 17, fresh air 29 (represented by dashed-line arrows) enters the fresh air supply duct 16 from the interior of the side stand 1 through the filter 26. It is replaced by air from the vicinity of the hot tub shortage, which enters the side stand 1 through the opening 27 and thereby effectively cools the drive of the exhaust air fan 13.

Die Frischluft 29 tritt beim Durchströmen des Frischluftzuführkanals 16 in einen intensiven, stufenweisen Wärme- übertragungsprozeß mit der Abluft 28 und wird erhitzt. Die Abluft 28 gibt dabei einen erheblichen Teil der in ihr enthaltenen, sonst nutzlos abgeführten Wärmemenge an die Frischluft 29 ab. Eventuell dabei aus der Abluft 28 austauendes Muldengleitmittel wie z. B. Silikonöl sammelt sich in den Luftverteilerkästen 8 und kann auf einfache Weise aus diesen entfernt werden.The fresh air 29 enters into an intensive, gradual heat transfer process with the exhaust air 28 when flowing through the fresh air supply duct 16 and is heated. The exhaust air 28 gives off a considerable part of the heat quantity contained therein, which is otherwise uselessly dissipated, to the fresh air 29. Eventually from the exhaust air 28 thawing slip lubricant such. B. silicone oil collects in the air distribution boxes 8 and can be easily removed from them.

Die erhitzte Frischluft 29 tritt aus der Ausblaseinrichtung 21 in den Mangelraum 25 ein. Sie trifft dort auf die in die erste Mangeleinheit 4 einlaufenden feuchten und kalten Wäschestücke und bewirkt eine Beschleunigung des Trocknungsprozesses durch eine Vorwärmung dieser Wäschestücke. Ungeachtet dessen ermöglicht jedoch das Einblasen der erhitzten Frischluft 29 in den Mangelraum 25 ein gleichmäßig hohes Temperaturniveau in diesem und spart wesentlich Energie, die sonst zum Erhitzen der Frischluft 29 durch die Mangelmulden 3 zusätzlich aufgebracht werden müßte.The heated fresh air 29 enters the deficiency space 25 from the blow-out device 21. There it meets the wet and cold laundry items entering the first ironer unit 4 and causes the drying process to be accelerated by preheating these laundry items. Irrespective of this, however, blowing the heated fresh air 29 into the shortage space 25 enables a uniformly high temperature level therein and saves a substantial amount of energy which would otherwise have to be additionally applied by the shortage troughs 3 to heat the fresh air 29.
