Description

Hochdruck-Dampfbügeleisen High pressure steam iron
Die Erfindung betrifft ein Bügeleisen mit einem die Bügel¬ fläche aufweisenden Grundteil und einem Gehäuseteil mit eine Griff, mit einer über dem Grundteil geführten Heizeinrich¬ tung, mit einer Verdampfereinrichtung auf der Oberseite der Grundplatte, die über Bohrungen mit der Unterseite dersel¬ ben in Verbindung steht, und einer Thermostateinrichtung zum Regeln der einstellbaren Temperatur des Grundteiles.The invention relates to an iron with a base part having the ironing surface and a housing part with a handle, with a heating device guided over the base part, with an evaporator device on the upper side of the base plate, which is connected to the underside thereof via bores stands, and a thermostat for regulating the adjustable temperature of the base part.
Bei einem solchen Bügeleisen ist das Grundteil üblicherwei- se als Guß- oder Druckgußteil, z.B. aus Aluminium, ausge¬ bildet. Dieses Grundteil weist auf seiner der Bügelfläche abgewandten Oberfläche eine Rillenstruktur auf, in der eine Heizeinrichtung eingegossen ist. Weiter sind auf der Grund¬ platte nach oben offene Dampfkammern angeformt, die mittels eines Deckels verschlossen werden, wobei zur Abdichtung zwischen Deckel und Grundteil eine Dichtung erforderlich ist. Das Formen des Gußteiles und Komplettieren mit der Ab¬ deckung ist komplizie'rt und aufwendig. Darüber hinaus ent¬ steht ein hohes Gewicht des Bügeleisens. In anderen Fällen werden die Damp kammern mit in die Sohle eingegossen. Wei¬ terhin gibt es Bügeleisen, in denen das Heizungsrohr in einem größeren Rohr direkt mitgeführt wird. Das führt aber zu Dampfüberhitzungen, da die Heizung sehr heiß wird. Wei¬ terhin ist die Wärmeübertragung auf die Bügelplatte sehr schlecht. Im übrigen sind die angeführten Lösungen alle sehr kostenintensiv.-In such an iron, the base part is usually cast or die-cast, e.g. made of aluminum. This base part has a groove structure on its surface facing away from the ironing surface, in which a heating device is cast. Furthermore, steam chambers which are open at the top and are closed by means of a cover are formed on the base plate, a seal being required for sealing between the cover and the base part. Forming the casting and completing it with the cover is complicated and expensive. In addition, there is a high weight of the iron. In other cases, the steam chambers are cast into the sole. There are also irons in which the heating pipe is carried directly in a larger pipe. However, this leads to steam overheating, since the heating becomes very hot. Furthermore, the heat transfer to the ironing plate is very poor. Otherwise, the solutions listed are all very cost-intensive.
Die Regelung der Temperatur erfolgt über einen Bimetall- Regler. Dessen Schaltkontakt sitzt direkt im Wärmefluß der heißen Bügeleisenplatte und ist damit sehr anfällig. Aufgabe der Erfindung ist es, das Bügeleisen der eingangs beschriebenen Art so auszubilden, daß es einfacher und ko¬ stengünstiger herstellbar ist. Nach einer Weiterbildung der Erfindung soll die Einrichtung zur Temperaturregelung der Bügelfläche so ausgebildet sein, daß sie eine längere Lebens¬ dauer hat und zuverlässiger arbeiten kann.The temperature is controlled by a bimetal controller. Its switch contact sits directly in the heat flow of the hot iron plate and is therefore very susceptible. The object of the invention is to design the iron of the type described in the introduction in such a way that it can be manufactured more easily and more cost-effectively. According to a development of the invention, the device for regulating the temperature of the ironing surface should be designed in such a way that it has a longer service life and can work more reliably.
Diese Aufgabe wird durch ein Bügeleisen der eingangs be¬ schriebenen Art gelöst, welches gemäß der Erfindung dadurch gekennzeichnet ist, daß das Grundteil als ebene Platte, die Heizeinrichtung als eine auf der Platte befestigte Heiz¬ schlange, und die Verdampfereinrichtung als eine ebenfalls auf der Platte befestigte rohrförmige Schlange ausgebildet ist.This object is achieved by an iron of the type described at the outset, which according to the invention is characterized in that the base part as a flat plate, the heating device as a heating coil attached to the plate, and the evaporator device as also on the plate attached tubular snake is formed.
Weitere Merkmale und Zweckmäßigkeiten der Erfindung ergeben sich aus der Beschreibung eines Ausführungsbeispieles an¬ hand der Figuren. Von den Figuren zeigen:Further features and advantages of the invention result from the description of an embodiment with reference to the figures. From the figures show:

Fig. 5 einen elektrischen Schaltplan für das Bügeleisen. Das Bügeleisen 1 weist ein Grundteil in Form einer ebenen Edel stahlplatte 2 aus VA-Material und ein Gehäuse 3 mit einem Grif 4 auf. Auf der Platte 2 ist mittels eines Sinter-Lötverfah¬ rens eine Heizschlange 5 aus VA-Material direkt auf der Platte 2 aufgelötet, so daß eine direkte Wärmeübertragung zwischen Heizschlange 5 und Platte 2 erfolgt. Die Heizschlan¬ ge 5 ist dabei so über die Platte geführt, daß möglichst alle Bereiche der Platte gleichmäßig erwärmt werden. Wie aus Fig. 2 ersichtlich ist, ist die Heizschlange 5 so ausgebildet, daß die eigentliche Heizwirkung an der Stelle 6 aufhört, von der ab die Heizschlange nicht mehr mit der Platte 2 in Kontakt steht und lediglich zu einem elektrischen Anschluß 7 führt.Fig. 5 is an electrical circuit diagram for the iron. The iron 1 has a base in the form of a flat stainless steel plate 2 made of VA material and a housing 3 with a handle 4. On the plate 2, a heating coil 5 made of VA material is soldered directly onto the plate 2 by means of a sintered soldering process, so that a direct heat transfer takes place between the heating coil 5 and the plate 2. The heating coil 5 is guided over the plate in such a way that, if possible, all areas of the plate are heated uniformly. As can be seen from Fig. 2, the heating coil 5 is designed so that the actual heating effect stops at point 6, from which the heating coil is no longer in contact with the plate 2 and only leads to an electrical connection 7.
Parallel zu der Heizschlange 5 verläuft eine weitere rohrför- . mige Schlange' 8, die ebenfalls im Sinter-Lötverfahren direkt auf der Platte 2 so aufgelötet ist, daß sie in möglichst wei¬ ten Bereichen in Berührungskontakt mit der Heizschlange 5 steht. Ein Ende 9 der Schlange 8 ist geschlossen, während das andere Ende mit einer Zuführung 11 für die Dampfzufuhr ausge- bildet ist. Die Schlange 8 steht über eine Vielzahl jeweils einen Abstand zueinander aufweisende Bohrungen bzw. Düsenlö¬ cher 12 durch die Platte 2 und die Schlange 8 hindurch mit der Bügelfläche 13 der Platte 2 verbunden. Die Schlange 8 und die Heizschlange 5 sind in den Kontaktbereichen zur Verbesse- rung des Wärmekontaktes ebenfalls miteinander verlötet. Die gezeigte Rohrführung ist eine mögliche Ausführung, und kann durch andere Varianten gleichen Prinzips variiert werden bzw. den Gegebenheiten angepaßt werden, wie z.B. für ein schmäle¬ res Bügeleisen zum Nähteöffnen.A further pipe support runs parallel to the heating coil 5. Mige snake ' 8, which is also soldered directly to the plate 2 in the sinter-soldering process so that it is in contact with the heating coil 5 in the widest possible areas. One end 9 of the coil 8 is closed, while the other end is formed with a feed 11 for the steam supply. The coil 8 is connected to the bracket surface 13 of the plate 2 through a plurality of bores or nozzle holes 12 which are spaced apart from one another through the plate 2 and the coil 8. The coil 8 and the heating coil 5 are also soldered to one another in the contact areas in order to improve the thermal contact. The pipe guide shown is a possible embodiment and can be varied by other variants of the same principle or adapted to the circumstances, such as for a narrow iron for opening seams.
Wie am besten aus Fig. 1 ersichtlich ist, ist ferner auf der Platte 2 ein sich über einen Längsbereich der Platte erstreckendes Rohr 14 aufgelötet. Dieses ist an einem Ende verschlossen und an seinem anderen Ende offen. In das Rohr ist ein Kapillarrohrfühler 15 eingesetzt, der über eine aus dem offenen Ende austretende Kapillare 16 mit einer eigent¬ lichen Regelschalteinrichtung 17 verbunden ist.As can best be seen from FIG. 1, a tube 14 extending over a longitudinal region of the plate is also soldered onto the plate 2. This is closed at one end and open at the other end. In the pipe a capillary tube sensor 15 is used, which is connected to an actual regulating switching device 17 via a capillary 16 emerging from the open end.
Wie am besten aus Fig. 3 ersichtlich ist, ist direkt auf dem mit der Platte 2 verbundenen Teil der Heizschlang 5 eine Schicht 18 aus Isoliermaterial vorgesehen. Eine weitere Schicht 19 aus Isoliermaterial ist über dem zu dem elektri¬ schen Anschluß 7 führenden und nicht mehr direkt erwärmten Teil der Heizschlange 5 angeordnet. Wie am besten aus Fig. 3 ersichtlich ist, weist das auf die Platte 2 aufgesetzte Ge¬ häuse 3 einen direkt auf der Platte aufsitzenden Randbereich 20 und einen haubenartigen Abschnitt 21, an dem der Griff 4 befestigt ist, auf. Der Randbereich 20 ist bevorzugt aus Teflon-Material oder einem anderen nicht wärmeleitenden Ma¬ terial gebildet, so daß keine direkte Wärmeübertragung von der Platte 2 auf den haubenartigen Abschnitt 21 erfolgt.As can best be seen from FIG. 3, a layer 18 of insulating material is provided directly on the part of the heating coil 5 connected to the plate 2. Another layer 19 of insulating material is arranged over that part of the heating coil 5 which leads to the electrical connection 7 and is no longer directly heated. As can best be seen from FIG. 3, the housing 3 placed on the plate 2 has an edge region 20 seated directly on the plate and a hood-like section 21 to which the handle 4 is fastened. The edge region 20 is preferably formed from Teflon material or another non-heat-conducting material, so that there is no direct heat transfer from the plate 2 to the hood-like section 21.
Zum Verbinden des Gehäuses 3 mit der Platte 2 sind auf der Oberfläche der Platte 2 in einem Abstand zwei Gewindebolzen 22, 23 aufgeschweißt. Auf diese ist jeweils eine Doppelmut¬ ter 24 aus Teflon oder einem anderen nicht wärmeleitenden Material aufgeschraubt. In die Gegenöffnung der Doppelmutter 24 ist eine durch den Griff 4 und den haubenartigen Ab- schnitt 21 des Gehäuses 3 hindurchgeführte Schraube 25 zum Verbinden des Gehäuses mit der Platte eingeschraubt. Über die entsprechenden Schrauben 25, die jeweilige Doppelmutter 24 und die Gewindebolzen 22, 23 werden somit Gehäuse und Platte fest miteinander verbunden. Durch die Doppelmuttern 24 wird eine Wärmeübertragung von der Platte auf das Gehäu¬ se vermieden. Wie am besten aus Fig. 5 ersichtlich ist, ist ein Anschlu߬ pol der Heizschlange 5 über eine Anschlußeinrichtung 25 mit einem Anschluß der Regelschalteinrichtung 17 verbunden, während der andere Pol der Heizschlange 5 über die Anschluß- einrichtung mit dem Null-Leiter der Stromzuführung 27 ver¬ bunden ist. Der andere Anschluß der Regelschalteinrichtung 17 ist mit dem Phaaenleiter der Stromzuführung verbunden. Weiterhin ist der Phasenleiter der Stromzuführung über einen Mikroschalter 28 mit einem Anschlußpunkt 29 verbunden, wel- eher die Dampfzufuhr zur Zuführung 11 betätigt.To connect the housing 3 to the plate 2, two threaded bolts 22, 23 are welded onto the surface of the plate 2 at a distance. A double nut 24 made of Teflon or another non-heat-conducting material is screwed onto each of these. A screw 25, which passes through the handle 4 and the hood-like section 21 of the housing 3, is screwed into the counter-opening of the double nut 24 for connecting the housing to the plate. The housing and plate are thus firmly connected to one another via the corresponding screws 25, the respective double nut 24 and the threaded bolts 22, 23. The double nuts 24 prevent heat transfer from the plate to the housing. As can best be seen from FIG. 5, a connecting pole of the heating coil 5 is connected to a connection of the control switching device 17 via a connecting device 25, while the other pole of the heating coil 5 is connected to the neutral conductor of the power supply 27 via the connecting device is connected. The other connection of the control switching device 17 is connected to the phase conductor of the power supply. Furthermore, the phase conductor of the power supply is connected via a microswitch 28 to a connection point 29 which rather actuates the steam supply to the supply 11.
Die von dem Kapillarrohrfühler 15 herkommende Kapillare 16 ist mit der .Regelschalteinrichtung 17 verbunden. Mikroschal¬ ter 28 und Regelschalteinrichtung 17 sind, wie am besten aus Fig. 3 ersichtlich ist, im Griff angeordnet.The capillary 16 coming from the capillary tube sensor 15 is connected to the control switching device 17. Microswitch 28 and regulating switching device 17 are arranged in the handle, as can best be seen in FIG. 3.
Im Betrieb fließt bei geschlossenem Schalter der Regelschalt¬ einrichtung 17 Strom durch die Heizschlange 5. Diese bzw. das sie umgebende Rohr wird erwärmt und gibt diese Wärme an die direkt mit ihr in wärmeleitendem Kontakt befindliche Platte 2 und an die ihr benachbarte rohrförmige Schlange 8 ab. Über den Kapillarrohrfühler 15 und die Regelschaltein¬ richtung 17 wird die Temperatur auf einen voreingestellten Wert eingeregelt.In operation, when the switch of the control switching device 17 is closed, current flows through the heating coil 5. This or the pipe surrounding it is heated and emits this heat to the plate 2 which is in direct thermal contact with it and to the adjacent tubular coil 8 . The temperature is adjusted to a preset value via the capillary tube sensor 15 and the control switching device 17.
Ist der Kontakt am Mikroschalter (28) geschlossen, kann der Dampf in die rohrförmige Schlange (8) eintreten, um dann über die Düsenlöcher (12) der Bügelfläche auf das zu bügeln¬ de Gut zu gelangen. In dem Dampfrohr wird innenwandig anlie- gend über den ganzen Rohrverlauf eine VA-Feder eingeführt, die evtl. mitgeführte Kondenswassertropfen aus der Zulei- tung verwirbelt und verdampft. Bei sehr feuchter Dampfquali- tät kann noch eine weitere Feder in den Innendurchmesser der erstgenannten eingeführt werden. Diese Verdampfung wird ge¬ fördert durch den Innenkontakt zwischen der Heizschlange (5) und der rohrförmigen Schlange (8), sowie beide zusammen wie¬ der mit der Platte (2). Ein Überhitzen des Dampfes ist je¬ doch ausgeschlossen, da über die enge Verbindung der Rohre (5, 8) mit der Platte (2) ein zügiger Wärmefluß gewährleistet ist und somit kein Stau entstehen kann.If the contact on the microswitch (28) is closed, the steam can enter the tubular coil (8) in order to then reach the material to be ironed via the nozzle holes (12) in the ironing surface. A stainless steel spring is inserted inside the steam pipe over the entire pipe run, which condensation drops that may have been carried along from the supply swirled and evaporated. If the steam quality is very moist, another spring can be inserted into the inner diameter of the former. This evaporation is promoted by the internal contact between the heating coil (5) and the tubular coil (8), and both together with the plate (2). Overheating of the steam is, however, ruled out, since the close connection of the pipes (5, 8) to the plate (2) ensures a rapid heat flow and therefore no jam can occur.
Durch das Aufbringen des Kapillarrohrfühlers 15 in den den Kapillarrohrfühler aufnehmenden und direkt mit der Platte 2 verbundenen Rohr 30 läßt sich eine sehr genaue Temperatur¬ regelung herstellen. Da der eigentliche Schaltkontakt im Griff angeordnet ist und somit gegen die heiße Platte 2~ wärmemäßig isoliert ist, wird die Lebensdauer des Schalt¬ kontaktes darüber hinaus erheblich vergrößert.By applying the capillary tube sensor 15 in the tube 30 receiving the capillary tube sensor and directly connected to the plate 2, a very precise temperature control can be established. Since the actual switching contact is arranged in the handle and is thus thermally insulated from the moderately hot plate 2 ~, the life of the Schalt¬ is also increased considerably beyond the contact.
Weil das die Heizschlange enthaltende Rohr, die rohrförmige Schlange 8 für die Dampfeinrichtung und die Platte 2 alle aus VA-Material, also aus dem gleichen Material gebildet sind, ergeben sich optimale Bedingungen für einander ent¬ sprechende Wärmeausdehnungen, so daß dadurch die Lebensdauer vergrößert wird.Because the tube containing the heating coil, the tubular coil 8 for the steam device and the plate 2 are all made of VA material, that is to say of the same material, there are optimal conditions for corresponding thermal expansions, so that the service life is thereby increased .
Da die von der Heizschlange 5 erzeugte Wärme wegen der da¬ rüber angeordneten Isolationsschichten 18, 19 und der wär- meisoliere'nden Doppelmuttern 24 nahezu vollständig in die Platte 2 geleitet wird, wird die bügelnde Person nicht durch abstrahlende Wärme belästigt, und darüber hinaus wird der Wirkungsgrad des Bügeleisens erhöht. Durch die relativ dünne Ausführung der Sohle (2), die zwi¬ schen 2 bis 3 mm dick ist, und der ebenfalls sehr flach ge¬ führten Heiz-, Verdampf- und Temperaturmeßebene der Rohre (5, 8 und 15), die ca. 8 mm beanspruchen, erhält man trotz der optimalen Wärmeisolation ein sehr flaches und mit ca. 1.200 g eines der leichtesten Industriebügeleisen überhaupt. Since the heat generated by the heating coil 5, because of the da¬ over arranged insulating layers 18, 19 and the heat-meisoliere 'intermeshing twin nuts 24 is almost completely introduced into the plate 2, the ironing person is bothered by radiating heat, and is moreover the efficiency of the iron increases. Due to the relatively thin design of the sole (2), which is between 2 to 3 mm thick, and the also very flat heating, evaporation and temperature measurement plane of the tubes (5, 8 and 15), which are approx. Claim 8 mm, you get a very flat and with approx. 1200 g one of the lightest industrial irons ever, despite the optimal thermal insulation.
