Description

Die Erfindung betrifft eine Bügelmaschine nach Art einer Mangel umfassend eine in einem Muldenbereich drehbar gelagerte Walze zur Bildung eines schalenförmigen Glättungsraumes für Textilien, wobei der Muldenbereich mit einer über die Muldenfläche wirkenden Heizeinrichtung versehen ist, die aus an der Rückseite der Muldenfläche angeordnetem Kanal oder Kanälen besteht, durch die ein aus Heißgas bestehendes Heizmedium strömt, wobei der Kanal oder die Kanäle mit einem für den Zustrom des Heizmediums gemeinsamen Eingangskanal verbunden sind sowie mit wenigstem einem Ausgangskanal für den Abluftstrom oder Abgas.The invention relates to a mangle type ironing machine comprising a roller rotatably mounted in a trough area for forming a cupped smoothing space for textiles, the trough area being provided with a heater acting over the trough surface consisting of a channel or channels disposed at the back of the trough surface through which a heating medium consisting of hot gas flows, wherein the channel or the channels are connected to an input channel common to the inflow of the heating medium and at least one output duct for the exhaust air flow or exhaust gas.

Aus dem Stand der Technik sind Bügelmaschinen nach Art einer Mangel bekannt, wobei in einem Muldenbereich eine Walze drehbar gelagert ist. Zwischen dem Muldenbereich und der Walze wird ein Glättungsraum für Textilien gebildet, wobei dieser mittels einer Heizeinrichtung erwärmt wird. Die Heizeinrichtung befindet sich hierbei an der Rückseite der Muldenaußenfläche, wo ein Kanalraum mit einem Kanal oder mehreren Kanälen vorgesehen ist, durch die das Heißgas strömt, um auf diese Weise die Glättungsfläche am Muldenbereich zu erwärmen.From the state of the art ironing machines are known in the manner of a defect, wherein in a trough region, a roller is rotatably mounted. Between the trough area and the roller, a smoothing room for textiles is formed, which is heated by means of a heater. The heater is in this case at the back of the trough outer surface, where a channel space is provided with a channel or more channels through which the hot gas flows, so as to heat the smoothing surface at the trough area.

In der DE 89 05 552 U1 oder der US 3 191 325 A ist eine durch Heißgas beheizte Muldenmangel in der dafür geeigneten konstruktiven Ausführung offenbart. Die hier offenbarte Muldenmangel umfasst einen Muldenbereich zur Bildung eines schalenförmigen Glättungsraumes für Textilien, welcher mit einer über die Muldenfläche wirkenden Heizeinrichtung versehen ist, die aus an der Rückseite der Muldenaußenfläche angeordneten Kanal oder Kanälen besteht, durch die ein aus Heißgas bestehendes Heizmedium strömt. Der Kanal oder die Kanäle sind mit einem für den Zustrom des Heizmediums gemeinsamen Eingangskanal verbunden, sowie mit wenigstens einem Ausgangskanal für den Abgasstrom.In the DE 89 05 552 U1 or the US 3,191,325 is a heated by hot gas trough deficiency in the appropriate structural design disclosed. The tray deficiency disclosed herein comprises a trough area for forming a bowl-shaped smoothing space for textiles which is provided with a heater acting over the trough area, consisting of a channel or channels disposed at the rear of the trough exterior through which a heating medium consisting of hot gas flows. The channel or channels are connected to an input channel common to the inflow of the heating medium and to at least one outlet channel for the exhaust gas flow.

Aus dem Stand der Technik sind auch Bügelmaschinen bekannt, welche eine leistungsstarke elektrische Heizeinrichtung aufweisen, die bauseitig nicht immer eine ausreichend dimensionierte elektrische Absicherung aufweist.Ironing machines are also known from the prior art, which have a powerful electric heating device, which does not always have sufficient electrical protection on site.

Die DE 36 43 901 A1 offenbart eine rein elektrisch beheizte Mulde für eine Mangel, bei der an der Muldenaußenseite Heizelemente angebracht sind. Um die Wärmeübertragung zu optimieren, sind die Heizelemente außenseitig in blockartigen Wärmeverteilungselementen eingebettet, die wiederrum flächig an der Muldenaußenseite anliegen. Die Blöcke sind außenseitig mit einer Wärmeisolierung versehen, um eine gute und gleichmäßige Wärmeübertragung nur zum Muldeninneren zu bewirken und Wärmeverluste zu vermeiden. Somit wird aufgrund des Nachteils der notwendigen elektrischen Absicherung oftmals auf gasbeheizte Mangeln zurückgegriffen. Diese haben trotz deutlich höherer installierter Heizleistung eine erheblich geringere Mangelleistung, das heißt, der Durchsatz der Wäsche pro Zeit ist gering, da die gasbeheizte Mangel einen erheblich schlechteren Gesamtwirkungsgrad besitzt als elektrisch beheizte Mangeln.The DE 36 43 901 A1 discloses a purely electrically heated trough for a defect, are mounted on the outside of the trough heating elements. In order to optimize the heat transfer, the heating elements are embedded on the outside in block-like heat distribution elements, which in turn rest flat on the outside of the bowl. The blocks are provided on the outside with a thermal insulation, in order to effect a good and uniform heat transfer only to the hollow interior and to avoid heat loss. Thus, due to the disadvantage of the necessary electrical protection often resorted to gas-heated mangles. These have despite much higher installed heating capacity, a significantly lower mangle performance, that is, the throughput of the laundry per time is low, since the gas-heated defect has a significantly poorer overall efficiency than electrically heated mangles.

Gasbeheizte Muldenmangeln haben in der Regel das Problem, dass die Temperatur im Muldeneinlauf stark absinkt, sobald Wäsche eingegeben wird. Die Mangelleistung sinkt dann, wobei die Wäsche feucht aus der Mangel kommt, so dass gegebenenfalls dabei das Finish der Wäsche leidet. Ursache dafür ist der schlechte Temperaturübergang von den heißen Rauchgasen, die etwa 450° C aufweisen, auf die Muldenfläche. Eine Aluminiummulde gibt dabei nur zwischen 100° und 200°C an die im Glättungsbereich befindlichen Textilien ab. Um hier eine effiziente Mangelung vorzunehmen, damit die Wäsche nicht feucht aus der Mangel kommt, wird die Mangelgeschwindigkeit dabei entsprechend heruntergeregelt. Bezüglich des Temperaturübergangs wird versucht, die heißen Gase über eine möglichst lange Strecke im Bereich des Muldeneinlaufs und auf der gesamten Mulde zu leiten. Hier werden viele Wirbelbleche eingesetzt, um auf diese Weise den Temperaturübergang zu verbessern. Wie bereits schon gesagt, wird durch das notwendige Herunterregeln der Mangelgeschwindigkeit entsprechend die Mangelleistung minimiert. Der Muldeneinlauf wird relativ im Vergleich zu einer rein elektrisch beheizten Mulde kühl und es kann zu Finish-Problemen kommen.Gas-fired bowl mangles usually have the problem that the temperature in the bowl inlet drops sharply as soon as laundry is entered. The deficiency then drops, the laundry comes wet from the defect, so possibly suffers while the finish of the laundry. The reason for this is the poor temperature transition of the hot flue gases, which have about 450 ° C, on the trough surface. An aluminum trough emits only between 100 ° and 200 ° C to the textiles located in the smoothing area. In order to make an efficient deficiency here, so that the laundry does not come damp from the defect, the deficiency rate is adjusted accordingly. With regard to the temperature transition, it is attempted to conduct the hot gases over as long a distance as possible in the region of the depression and on the entire depression. Here many vortex plates are used to improve in this way the temperature transition. As already said, the deficiency is minimized by the necessary reduction of deficiency speed. The trough inlet is relatively cool compared to a purely electrically heated trough and it can lead to finish problems.

Bei der rein elektrisch beheizten Mulde haben die Heizkörper im Bereich des Muldeneinlaufs eine höhere Dichte als am Rest des Umfangs. Dadurch steigt auch die Elektrofläche oder die übertragene Energie zum Trockenen und Glätten des Mangelgutes. Bei der rein gasbeheizten Mulde sieht die Situation anders aus. Hier herrscht im Muldeneinlauf ein höheres Temperaturgefälle zwischen den Rauchgasen, die die Energie in die Mulde übertragen. Die Temperatur nimmt aber beim Mangeln trotzdem viel stärker ab als bei einer elektrisch beheizten Mulde.In the purely electrically heated trough radiators have a higher density in the region of the trough inlet than at the rest of the circumference. As a result, the electrical surface or the energy transferred to dry and smooth the deficient good increases. The situation is different with the purely gas-heated hollow. Here, a higher temperature gradient prevails in the trough inlet between the flue gases, which transfer the energy into the trough. Nevertheless, the temperature decreases much more when ironing than with an electrically heated trough.

Der Erfindung stellt sich somit das Problem, eine gasbeheizte Bügelmaschine derart weiterzubilden, die die geschilderten Nachteile überwindet, wobei insbesondere gewährleistet werden soll, dass eine bessere Mangelleistung der Bügelmaschine bereitgestellt werden soll.The invention thus raises the problem of developing a gas-heated ironing machine in such a way that overcomes the disadvantages described, in particular, to ensure that a better shortage of ironing machine to be provided.

Erfindungsgemäß wird dieses Problem durch eine Bügelmaschine mit den Merkmalen des unabhängigen Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden abhängigen Ansprüchen.According to the invention, this problem is solved by an ironing machine with the features of independent claim 1. Advantageous embodiments and modifications of the invention will become apparent from the following dependent claims.

Die mit der Erfindung erreichten Vorteile bestehen darin, dass in Folge einer elektrischen Zusatzheizung des Muldeneinlaufs, ohne dass die elektrische Absicherung der Bügelmaschine erhöht werden muss, die Temperatur im Muldeneinlauf bei gleicher Mangelgeschwindigkeit deutlich höher als ohne elektrische Zusatzheizung ist. Die Mangelgeschwindigkeit muss weniger reduziert werden, so dass die Mangelleistung der Bügelmaschine deutlich steigt im Vergleich zu rein gasbeheizten Varianten. Daraus folgernd ergibt sich eine Steigerung der Leistungsdaten bei gleicher elektrischer Anschlussleistung.The advantages achieved by the invention are that, as a result of an electric auxiliary heating of the trough inlet, without the electrical protection of the ironing machine must be increased, the temperature in the trough inlet at the same lack of speed significantly higher than without electric auxiliary heating. The shortage speed must be reduced less, so that the shortage of ironing machine significantly increases compared to purely gas-heated variants. As a result, there is an increase in the performance data for the same electrical connection performance.

Durch den Einsatz von zusätzlichen Heizstäben im Muldeneinlauf kann diese Temperatur bei gleicher Mangelgeschwindigkeit und damit auch die Mangelleistung merklich angehoben werden. Der Einbau einer zusätzlichen Heizeinrichtung ist besonders einfach umzusetzen, da die elektrobeheizte Mulde und die gasbeheizte Mulde im Aufbau identisch sind. Ein Nachrüsten ist daher durchaus denkbar. Die Aufnahmen für die Heizkörper sind also schon vorhanden. Prinzipiell ist es auch möglich, die elektrische Zusatzheizung nur im Bedarfsfall durch den Nutzer handgesteuert oder manuell beziehungsweise durch die Maschinensteuerung automatisch zu aktivieren. Im Leerlauf, wenn der Leistungsbedarf nicht so hoch wird, wird nur mit Gas beheizt, sobald Leistung abgefordert wird, schaltet sich die elektrische Zusatzheizung ein. Da Gas günstiger als elektrische Energie ist, wird hier noch eine Kostenoptimierung durchgeführt.Through the use of additional heating elements in the trough inlet, this temperature can be significantly increased at the same shortage speed and thus also the shortage. The installation of an additional heating device is particularly easy to implement, since the electrically heated trough and the gas-heated trough are identical in construction. Retrofitting is therefore quite conceivable. The recordings for the radiators are already there. In principle, it is also possible to activate the electric auxiliary heater manually only when needed by the user or automatically or manually by the machine control. When idling, if the power requirement is not so high, is heated only with gas, as soon as power is requested, the additional electric heater turns on. Since gas is cheaper than electrical energy, a cost optimization is still carried out here.

Erfindungsgemäß ist hierbei die Muldenfläche mit einer lokal wirkenden zusätzlichen Heizeinrichtung versehen zum Ausgleich von über die Glättungsfläche auftretenden Temperaturdifferenzen beim Mangelvorgang. Die Heizeinrichtung ist im Bereich des Einzugs beziehungsweise des Einlaufs in der Mulde angeordnet. Hierbei besteht die Heizeinrichtung aus bereichsweise segmentierten Elementen. Die Heizeinrichtung besteht weiterhin aus wenigstens einem elektrisch beheizbaren Heizstab, vorzugsweise wenigstens zwei Heizstäben. Dabei sind die einzelnen Heizstäbe mittels einer Steuerung im Bedarfsfall aktivierbar beziehungsweise deaktivierbar. Die Heizstäbe als solches sind an der Rückseite der Mulde am Muldeneinlauf angeordnet. Dabei liegen die Heizstäbe in an der Rückseite der Muldenfläche bzw. der Wangenteils vorhandenen rippenartigen Kanälen, wobei zumindest zwei Heizstäbe in jeweils einer Rippe angeordnet sind. Die Heizstäbe können hierbei im Bedarfsfall auch manuell zugeschaltet werden.According to the invention, the trough surface is provided here with a locally acting additional heating device for compensating temperature differences occurring over the smoothing surface during the shortage process. The heater is arranged in the region of the intake or the inlet in the trough. Here, the heater consists of partially segmented elements. The heating device furthermore consists of at least one electrically heatable heating rod, preferably at least two heating rods. In this case, the individual heating elements can be activated or deactivated by means of a control in case of need. As such, the heating elements are arranged at the rear of the trough at the trough inlet. In this case, the heating elements are located in the back of the trough surface or the cheek part existing rib-like channels, wherein at least two heating elements are arranged in each case a rib. If required, the heating elements can also be switched on manually.

An embodiment of the invention is shown purely schematically in the drawings and will be described in more detail below. It shows:
FIG. 1
a perspective view of an ironing machine in the manner of a defect,
FIG. 2
a perspective view of the roller with the trough area and an imported textile, and
FIG. 3
a side view in a sectional view of the ironing machine according to Fig.1 ,

Die Figur 1 zeigt eine Bügelmaschine 1 nach Art einer Mangel, wobei die Bügelmaschine 1 ein Gestell 2 umfasst, in dem eine Walze 3 drehbar gelagert ist. Die Walze 3 dreht sich dabei in einem Muldenbereich 4, zur Bildung eines schalenförmigen Glättungsraumes 5, wie er beispielsweise in der Figur 2 angedeutet ist. Durch den Glättungsraum 5 wird ein Textil 6 über eine Eingabe 7 eingezogen, so dass dann über den Teilumfang der Walze 3 die Wäsche geglättet wird. Der Muldenbereich bzw. die Muldenwange 4 ist hierbei mit einer über die Muldenfläche 8 wirkenden Heizeinrichtung 9 versehen, die aus an der Rückseite der Muldenaußenfläche angeordneten Kanal oder Kanälen 10 besteht. Durch den Kanal oder die Kanäle 10 strömt ein aus Heißgas bestehendes Heizmedium H, wobei der Kanal oder die Kanäle 10 mit einem für den Zustrom des Heizmediums H gemeinsamen Eingangskanal 11 verbunden sind sowie mit wenigstens einem Ausgangskanal 12 für den Abluftstrom oder den Abgasstrom A.The FIG. 1 shows an ironing machine 1 in the manner of a defect, wherein the ironing machine 1 comprises a frame 2, in which a roller 3 is rotatably mounted. The roller 3 rotates in a trough area 4, to form a cup-shaped smoothing space 5, as it is for example in the FIG. 2 is indicated. Through the smoothing space 5, a textile 6 is drawn in via an input 7, so that then over the partial circumference of the roller 3, the laundry is smoothed. The trough region or the trough cheek 4 is hereby provided with a heating device 9 which acts via the trough surface 8 and consists of a channel or channels 10 arranged on the rear side of the trough outer surface. A heating medium H consisting of hot gas flows through the channel or channels 10, the channel or channels 10 being connected to an inlet channel 11 common to the inflow of the heating medium H, and to at least one outlet channel 12 for the exhaust air flow or the exhaust gas flow A.

Wie insbesondere aus der Figur 3 zu erkennen ist, ist die Muldenfläche 8 mit einer lokal wirkenden zusätzlichen Heizeinrichtung 13 versehen zum Ausgleich von über die Muldenfläche 8 auftretenden Temperaturdifferenzen beim Mangelvorgang. Dabei ist die zusätzliche Heizeinrichtung 13 im Bereich des Einzugs 7 des Muldenbereichs 4 angeordnet, wie dies deutlich aus der Figur 3 zu erkennen ist.As in particular from the FIG. 3 can be seen, the trough surface 8 is provided with a locally acting additional heater 13 to compensate for the temperature differences occurring over the trough surface 8 during the mangle process. In this case, the additional heating device 13 is arranged in the region of the intake 7 of the trough region 4, as can be clearly seen from FIG FIG. 3 can be seen.

Die Heizeinrichtung 13 besteht hierbei aus bereichsweise segmentierten Elementen, welche aus wenigstens zwei elektrisch beheizbaren Heizstäben 14 und 15 besteht. Dabei sind die einzelnen Heizstäbe 14 und 15 mittels einer Steuerung im Bedarfsfall aktivierbar beziehungsweise deaktivierbar.The heater 13 here consists of partially segmented elements, which consists of at least two electrically heatable heating elements 14 and 15. In this case, the individual heating elements 14 and 15 can be activated or deactivated by means of a control in case of need.

Wie aus der Figur 3 zu erkennen ist, sind die Heizstäbe 14 und 15 an der Rückseite der Muldenfläche 8 am Muldeneinlauf 7 angeordnet. Die Heizstäbe 14 und 15 selbst sind in an der Rückseite der Muldenfläche 8 vorhandenen rippenartigen Kanälen 16 angeordnet. Dabei können die Heizstäbe 14, 15 in jeweils einem Kanal 16, der von zwei benachbarten Rippen 16a hinsichtlich seiner Breite begrenzt ist, eingesetzt bzw. eingepresst sein. Die Heizstäbe sind dabei automatsch durch die Steuerung 17 oder manuell mittels einer Bedienhandlung durch den Benutzer im Bedarfsfall einschaltbar. Die elektrische Heizeinrichtung 13 kann auch separat ohne die Beheizung durch Heißgas aktiviert bzw. betrieben werden, beispielsweise wenn ein kurzer Mangelvorgang mit geringer Heizleistung durchgeführt werden soll. Dann würde das Hochfahren der Heizeinrichtung 9 zu viel Zeit und Energie verbrauchen.Like from the FIG. 3 can be seen, the heating elements 14 and 15 are arranged on the back of the trough surface 8 at the trough inlet 7. The heating elements 14 and 15 themselves are arranged in rib-like channels 16 provided on the rear side of the trough surface 8. In this case, the heating elements 14, 15 in each case a channel 16 which is bounded by two adjacent ribs 16a in terms of its width, be inserted or pressed. The heating elements are automatically switched on by the controller 17 or manually by means of an operator action by the user, if necessary. The electric heater 13 may also be activated or operated separately without the heating by hot gas, for example, when a short deficiency operation with low heating power to be performed. Then the start-up of the heater 9 would consume too much time and energy.

Es versteht sich nun von selbst, dass, wenn Wäsche in die Bügelmaschine 1 eingeführt wird und in Folge der abnehmenden Temperatur im Einzugsbereich 7 die Heizleistung nachlässt, dann die zusätzliche Heizeinrichtung 13 zuschaltbar ist, so dass die Mangelgeschwindigkeit beibehalten werden kann, um auf diese Weise einen besseren Mangeldurchsatz zu erzielen.It goes without saying that when laundry is introduced into the ironing machine 1 and the heating power is reduced as a result of the decreasing temperature in the intake region 7, then the additional heating device 13 is switchable, so that the deficiency speed can be maintained, in this way to achieve a better shortage of throughput.
