Definitions
- the invention relates to an electric iron with an electrically heated soleplate and an aerosol atomizing device.
- the known steam irons evaporate water with the help of the radiator for normal ironing in a specially designed steam chamber.
- the water is fed dropwise to the steam chamber via a valve and, after evaporation, leaves the sole through channels provided for this purpose.
- a large amount of electrical power is required for heating and evaporating the water, which is not available for the actual ironing process and causes unnecessary costs.
- pressure-free aerosol atomizers are known, in which an ultrasonic generator is set in vibration with the aid of a piezo ceramic. The cold water atomization via the previous steam channels on the ironing surface of the soleplate is included Such aerosol atomizers are not possible, since the pressure of the iron against the items to be ironed and the fabric density counteract the aerosol outlet during ironing.
- the iron according to the invention can advantageously be equipped with a pressure-free aerosol atomization device, e.g. B. a piezo ceramic, which is set in motion by an ultrasonic frequency generator. Due to the low electrical power requirement for such mechanical atomizing devices, the heating element in the sole can be significantly smaller than in known steam irons. The calcification of the steam chamber and the steam channels known with steam irons is also eliminated, as a result of which the service life of the iron according to the invention is extended.
- a pressure-free aerosol atomization device e.g. B. a piezo ceramic
- the horseshoe-shaped, oval or round sole encompasses the atomization chamber in a frame shape, as a result of which the ironing surface of the soleplate can be significantly reduced compared to the known soleplate. As a result, the material requirements and the manufacturing costs for the soleplate are extremely low.
- the ironing material is advantageously first moistened via the atomizing device and then smoothed with the hot soleplate, as a result of which the moisture can penetrate deeper into the ironing material and does not already evaporate on the surface as in the known steam irons.
- the iron soleplate 1 of an iron (not shown) shown in FIGS. 1 to 3 is almost horseshoe-shaped and the iron soleplate 1 has a frame-shaped atomization chamber 2 which is open towards the ironing surface.
- the spray nozzle 4 of an air / cold water atomization device 3 opens inside the atomization chamber 2.
- the ironing surface 5 of the soleplate 2 is electrically heated by a heating element 6.
- the atomization chamber 2 is open at the rear. In the further embodiment shown in FIGS. 4 and 5, the atomization chamber 2 is designed to be closed at the rear.

Abstract
Description
Die Erfindung betrifft ein elektrisches Bügeleisen mit einer elektrisch beheizten Bügelsohle und einer Aerosol-Zerstäubungseinrichtung.The invention relates to an electric iron with an electrically heated soleplate and an aerosol atomizing device.
Zur Erzielung eines optimalen Bügelergebnisses ist es bekannt, mit Heißdampf zu bügeln oder das Bügelgut vor dem Bügeln von Hand oder mit einer am Bügeleisen vorgesehenen Sprüheinrichtung mit Wasser zu befeuchten.In order to achieve an optimal ironing result, it is known to iron with superheated steam or to dampen the items to be ironed with water before ironing by hand or with a spray device provided on the iron.
Die bekannten Dampfbügeleisen verdampfen Wasser mit Hilfe des zum normalen Bügeln vorhandenen Heizkörpers in einer speziell dafür vorgesehenen Dampfkammer. Das Wasser wird der Dampfkammer tropfenweise über ein Ventil zugeführt und verläßt nach dem Verdampfen die Sohle durch dafür vorgesehene Kanäle. Für das Erhitzen und das Verdampfen des Wassers wird eine große elektrische Leistung benötigt, die dem eigentlichen Bügelvorgang nicht zur Verfügung steht und unnötige Kosten verursacht.The known steam irons evaporate water with the help of the radiator for normal ironing in a specially designed steam chamber. The water is fed dropwise to the steam chamber via a valve and, after evaporation, leaves the sole through channels provided for this purpose. A large amount of electrical power is required for heating and evaporating the water, which is not available for the actual ironing process and causes unnecessary costs.
Es ist auch bekannt, daß durch das Befeuchten des Bügelgutes mit einem Wasser/Luft-Aerosol in Verbindung mit Wärme ein gutes Bügelergebnis erzielbar ist. So ist aus der US-PS 3,670,433 ein Bügeleisen mit einer Aerosol-Zerstäubungseinrichtung bekannt. Diese Einrichtung besteht aus einer herkömmlichen Sprühdose, die in das Bügeleisen einsetzbar ist. Das Aerosol wird unter Druck über im Bügeleisen vorgesehene Kanäle auf das Bügelgut gesprüht. Diese bekannte Aerosol-Zerstäubungseinrichtung kann die thermische Verdampfung bei Bügeleisen nicht ersetzen.It is also known that a good ironing result can be achieved by moistening the ironing material with a water / air aerosol in conjunction with heat. An iron with an aerosol atomization device is known from US Pat. No. 3,670,433. This device consists of a conventional spray can that can be inserted into the iron. The aerosol is sprayed onto the ironing material under pressure via channels provided in the iron. This known aerosol atomization device cannot replace the thermal evaporation in irons.
Darüber hinaus sind drucklos arbeitende Aerosol-Zerstäuber bekannt, bei denen mit Hilfe einer Piezo-Keramik ein Ultraschall-Generator in Schwingungen versetzt wird. Die Kaltwasserzerstäubung über die bisherigen Dampfkanäle an der Bügelfläche der Bügelsohle ist mit derartigen Aerosol-Zerstäubern nicht möglich, da beim Bügeln der Anpreßdruck des Bügeleises auf das Bügelgut und die Gewebedichte dem Aerosol-Austritt entgegenwirken.In addition, pressure-free aerosol atomizers are known, in which an ultrasonic generator is set in vibration with the aid of a piezo ceramic. The cold water atomization via the previous steam channels on the ironing surface of the soleplate is included Such aerosol atomizers are not possible, since the pressure of the iron against the items to be ironed and the fabric density counteract the aerosol outlet during ironing.
Ausgehend von dem vorbekannten Stand der Technik ist es die Aufgabe dieser Erfindung, ein Bügeleisen zu schaffen, das die Nachteile der bekannten Dampfbügeleisen nicht aufweist und bei dem die bekannte thermische Verdampfung durch eine mechanische Zerstäubung von Wasser ersetzt wird.Starting from the prior art, it is the object of this invention to provide an iron which does not have the disadvantages of the known steam iron and in which the known thermal evaporation is replaced by mechanical atomization of water.
Gelöst wird diese Aufgabe durch die kennzeichnenden Merkmale des Anspruchs 1.This object is achieved by the characterizing features of
Durch die erfindungsgemäße Bügelsohle, die rahmenförmig eine Zerstäubungskammer umfaßt, und in der eine mechanische Zerstäubungseinrichtung angeordnet ist, wird erreicht, daß das erfindungsgemäße Bügeleisen vorteilhaft mit einer drucklos arbeitenden Aerosol-Zerstäubungseinrichtung ausgerüstet werden kann, z. B. eine Piezo-Keramik, die von einem Ultraschallfrequenz-Generator in Schwingungen versetzt wird. Durch den geringen elektrischen Leistungsbedarf für derartige mechanische Zerstäubungseinrichtungen kann der Heizkörper in der Sohle wesentlich kleiner sein als bei bekannten Dampfbügeleisen. Auch das bei Dampfbügeleisen bekannte Verkalken der Dampfkammer und der Dampfkanäle entfällt, wodurch die Lebensdauer des erfindungsgemäßen Bügeleisens verlängert wird. Die hufeisenförmig, oval oder rund ausgebildete Sohle umfaßt die Zerstäubungskammer rahmenförmig, wodurch die Bügelfläche der Bügelsohle gegenüber den bekannten Bügelsohlen wesentlich verkleinert werden kann. Hierdurch sind der Materialbedarf sowie die Herstellkosten für die Bügelsohle außerordentlich gering. Vorteilhaft wird beim Bügeln erst das Bügelgut über die Zerstäubungseinrichtung befeuchtet und dann mit der heißen Bügelsohle geglättet, wodurch die Feuchtigkeit tiefer in das Bügelgut eindringen kann und nicht wie bei den bekannten Dampfbügeleisen bereits an der Oberfläche verdampft.Due to the soleplate according to the invention, which comprises a frame-shaped atomization chamber, and in which a mechanical atomization device is arranged, it is achieved that the iron according to the invention can advantageously be equipped with a pressure-free aerosol atomization device, e.g. B. a piezo ceramic, which is set in motion by an ultrasonic frequency generator. Due to the low electrical power requirement for such mechanical atomizing devices, the heating element in the sole can be significantly smaller than in known steam irons. The calcification of the steam chamber and the steam channels known with steam irons is also eliminated, as a result of which the service life of the iron according to the invention is extended. The horseshoe-shaped, oval or round sole encompasses the atomization chamber in a frame shape, as a result of which the ironing surface of the soleplate can be significantly reduced compared to the known soleplate. As a result, the material requirements and the manufacturing costs for the soleplate are extremely low. When ironing, the ironing material is advantageously first moistened via the atomizing device and then smoothed with the hot soleplate, as a result of which the moisture can penetrate deeper into the ironing material and does not already evaporate on the surface as in the known steam irons.
