Description
• * a• * a
-2--2-
Allgemeines:General:
Dampfbügler werden in neuerer Zeit mit PTC-Heizelementen ausgerüstet.Steam irons are now equipped with PTC heating elements.
Die Heizleistung dieser PTC ist jedoch gegenüber der Heizleistung normaler Elektroheizungen als gering zu bezeichnen.However, the heating output of this PTC is low compared to the heating output of normal electric heaters.
Setzt man diese PTC-Heizungen in einen mit seitlichen Schlitzen versehenen Käfig, so kann man damit einen großen Teil der in einem Tank befindlichen Wassermenge in dem Dampfbügler weitgehend von der Aufheizung ausschließen und damit die Heizleistung des PTC-Heizelementes konzentrieren.If you place these PTC heaters in a cage with slots on the side, you can largely exclude a large part of the water in the tank in the steam iron from heating up and thus concentrate the heating power of the PTC heating element.
Die herkömmliche Art die PTC-Heizelemente in den Käfig im Tank des Dampfbüglers einzubauen ist eine waagrechte Lagerung des Heizelementes.The conventional way of installing the PTC heating elements in the cage in the tank of the steam iron is to mount the heating element horizontally.
Dies hat jedoch den Nachteil, daß durch die seitlichen Schlitze des Käfigs Dampfblasen nach außen gedrückt werden, die eine weitere starke Vermischung des Wassers inner- und außerhalb des Käfigs bewirken. Die Konzentration der Heizleistung ist damit ungenügend.However, this has the disadvantage that steam bubbles are pushed out through the side slots of the cage, causing further mixing of the water inside and outside the cage. The concentration of the heating power is therefore insufficient.
Die an dem PTC-Heizelement sich bildenden Dampfblasen behindern die Energieübertragung an das Wasser. Das ist besonders im Bodenbereich des PTC-Heizelemendtes der Fall.The steam bubbles that form on the PTC heating element hinder the energy transfer to the water. This is particularly the case in the base area of the PTC heating element.
Der vorzugsweise aus Kunststoff gefertigte Käfig neigt zum Verzug durch die Hitzeeinwirkung.The cage, which is preferably made of plastic, tends to warp due to the effects of heat.
Normale Dampfbügler werden ohne Ein-Aus-Schalter gebaut, da die PTC Heizelemente selbstregelnd sind. Das birgt die Gefahr, daß ein solches Gerät bei Undichtigkeit durch Risse beim Herunterfallen usw. elektrischen Kontakt zwischen Wasser und/oder PTC-Heizelement erhält.Normal steam irons are built without an on-off switch because the PTC heating elements are self-regulating. This poses the risk that such a device could come into electrical contact between the water and/or the PTC heating element if it leaks due to cracks, if it is dropped, etc.
Beschreibung der Verbesserung
Diese Nachteile vermeidet die folgende Erfindung.Description of the improvement
The following invention avoids these disadvantages.
Dazu wird das PTC-Heizelement nicht waagerecht und/oder senkrecht eingebaut sondern in den jeweils besten räumlichen Winkeln (1), die eine schnelle Loslösung der Dampfblasen von dem PTC-Heizelement ermöglichen.For this purpose, the PTC heating element is not installed horizontally and/or vertically but at the best spatial angles (1) that allow the steam bubbles to be quickly released from the PTC heating element.
Die seitlich angebrachten Schlitze werden durch eine oder mehrere Bohrungen und/oder Schlitze im Boden des Käfigs (2) ersetzt.The slots on the sides are replaced by one or more holes and/or slots in the bottom of the cage (2).
Um ein Anlegen des Käfigs an die Außenwand bzw. direkt an das PTC-Heizelement zu
verhindern werden innen und/ oder außen Distanzrippen (3) an der Käfigwand angebracht.
Das Oberteil des Käfigs wird zur Weiterleitung des Dampfes zur Austrittsöffhung einteilig (4)
mit der Dampfleitung ausgelegt bzw. soweit seitlich verlängert, bis eine Prallwand (5) erreicht
wird, die Dampfund Wasser trennt, bevor der Dampf aus dem Gerät austritt.
Die beiliegende Zeichnung Nr. 1 zeigen die Zusammenstellung von Tank, PTC-Heizelement
Käfig mit Bohrungen und Rippen in einer bevorzugten Anordnung.To prevent the cage from coming into contact with the outer wall or directly with the PTC heating element, spacer ribs (3) are attached to the inside and/or outside of the cage wall.
To direct the steam to the outlet opening, the upper part of the cage is designed as a single piece (4) with the steam line or is extended laterally until a baffle (5) is reached, which separates the steam and water before the steam exits the device.
The attached drawing No. 1 shows the assembly of tank, PTC heating element cage with holes and fins in a preferred arrangement.
Die beiliegenden Zeichnungen Nr. 2 und Nr. 3 zeigen die Anordnung verschiedener Ein-Aus-Schalter an einem Dampfbügler vorgeschilderter Art.The attached drawings No. 2 and No. 3 show the arrangement of various on-off switches on a steam iron of the type described.
