Between the legs 60, 62, a recess 64 is provided, in which the designed as a setting wheel actuator 70 partially protrudes with its circumference, so that its control surface 74 may come into contact with the active surface 52 of the lever 50.

- the fin 76 points to the left, for example.
- a toothed circular segment 78 is formed on the back of the actuator designed as Stellrad 70, which is in engagement with a U-shaped spring clip 82.
- the spring clip 82 forms, in cooperation with the circular segment 78, an end stop for the rotary movement of the setting wheel.
- the teeth of the circle segment 78 give the user a feeling for the distance traveled adjustment of the thumbwheel, when the teeth slide on adjustment of the thumbwheel over the spring clip 82, wherein the teeth in cooperation with the spring clip 82 give a good perceptible noise. Furthermore, the spring clip 82 causes a restoring force when the actuator 70 is brought into that end position which corresponds to the maximum amount of steam, for example for a short and violent burst of steam at which the maximum amount of water enters the evaporator chamber 22. When the user releases the actuator 70 in this position, the actuator 70 automatically moves or rotates to a position corresponding to a smaller amount of steam.

- the needle 38 has been moved upwards out of the opening 26 of the valve seat 36 and releases the opening 26 (FIG. Fig. 3c ).
- the lever foot 56 is now flat on the valve-active surface 46 of the cap 44.
- Fig. 4a and 4b clearly show the trained as Stellrad actuator 70 in the two extreme positions with closed drip valve 32 (FIG. Fig. 4a ) and completely opened drip valve 32 (FIG. Fig. 4b ). Further, a pivot 84 can be seen, around which the set as a setting wheel actuator 70 is pivotable.
- the teeth make with the spring clip 82 on the one hand a good perceptible noise when the actuator designed as a dial 70 is rotated. Furthermore, the spring clip 82 generates a restoring force of the actuator 70 when the actuator 70 is brought into that end position in which the circular segment 78 has its elevation. This position corresponds to the maximum amount of steam, eg for a short burst of steam ("boost function"), in which the maximum amount of water enters the evaporator chamber 22. If the user then releases the actuator 70, it automatically moves or rotates by the action of the spring clip 82 and the flank of the elevation inclined towards the row of teeth to a position which corresponds to a smaller amount of steam.

Advantageously, the actuator can be arranged as needed away from the drip valve. The lever can be easily adjusted according to the distance of the actuator from the drip valve. The actuator can be adjusted in size to his liking, so that a greater freedom of design is given. The actuator can be made particularly small, which increases the ease of use for the user. If steam is to be dispensed, the user usually actuates the actuator during a bow movement z. B. with the thumb of the hand, which leads the steam iron. A small actuator is easier to operate and less impact on the handle of the steam iron. Furthermore, a small movement of the actuator can be conveniently converted into a large movement of the valve rod by the lever,

Der Hebel 50 erstreckt sich zwischen dem Steller 30 und dem Tropfventil 32. Der als Stellrad ausgebildete Steller 70 weist eine Drehachse 80 auf, die quer, bevorzugt senkrecht, zur Ventilachse 28 (Längsachse) der Ventilstange 34 ausgebildet ist.Furthermore, the regulating
Der Hebel 50 weist eine gekröpfte Form auf mit einem Hebelfuß 56, der auf der Ventil-Wirkfläche 46 gleiten kann und einen vom Hebelfuß 56 abgewinkelten Hebelkopf 54, der eine Wirkfläche 52 aufweist, die als Gegenfläche zu einer Steuerfläche 74 des Stellers 70 dient. Die Wirkfläche 52 des Hebels 50 ist versetzt neben der Ventilstange 34 angeordnet. Dadurch kann der Steller 70 axial neben dem Tropfventil 32 angeordnet sein.The

Die Steuerfläche 74 des Stellers 70 steuert eine Bewegung des Tropfventils 32, indem bei einer Verdrehung des als senkrecht stehendes Stellrad ausgebildeten Stellers 70 dieser mit seiner Steuerfläche 74 die Ventilstange 34 abhängig von einer Position der Steuerfläche 74 bezogen auf eine Wirkfläche 52 des Hebels 50 mit Druck beaufschlagt.The
Die Steuerfläche 74 des Stellers 70 weist eine schneckenförmige Steuerkurve auf, die entlang der Steuerfläche 74 vom Rand des Stellrads nach innen läuft. Die Steuerfläche 74 ändert damit entlang ihrer Längserstreckung ihren Abstand zur Drehachse 80 des Stellrads. Das Stellrad ist senkrecht angeordnet, so dass dessen Drehachse 80 senkrecht zur Ventilachse 28 ausgerichtet ist. Ist die Steuerfläche 74 mit der Wirkfläche 52 des Hebels 50 in Kontakt, wird diese Wirkfläche 52 parallel zur Ventilstange 34 verschoben. Bedient werden kann der Steller 70 über eine am Umfang abstehende Finne 76, die ein Anwender bequem z.B. mit seinem Daumen um die Drehachse 80 verdrehen kann.The
Der vorzugsweise gekröpft ausgebildete Hebel 50 ist in einem nicht dargestellten Drehlager gehäusefest fixiert, wozu Zapfen 58 am freien Ende des Hebelkopfs 54 vorgesehen sind. Die Zapfen 58 geben die Schwenkachse vor. Der Hebelkopf 54 ist U-förmig ausgebildet mit zwei Schenkeln 60, 62, welche jeweils eine Zapfen 58 tragen, die in ein entsprechendes Drehlager eingeführt werden können, um den Hebel 50 schwenkbar zu machen. Zwischen den Schenkeln 60, 62 ist eine Aussparung 64 vorgesehen, in welche der als Stellrad ausgebildete Steller 70 teilweise mit seinem Umfang hineinragt, so dass dessen Steuerfläche 74 mit der Wirkfläche 52 des Hebels 50 in Kontakt kommen kann. Die Kontaktfläche 52 ist durch die Oberseite einer nicht näher bezeichneten Querstrebe zwischen den Schenkeln 60, 62 gebildet. In der Seitenansicht in

In dieser Position des Stellers 70 und des Tropfventils 32 ragt aus einer Öffnung 26 des Ventilsitzes 36 eine Nadel 38 der Ventilstange 34 heraus und verschließt die Öffnung 26, wie in

Erkennbar ist hier, dass das Kreissegment 78 an seinen freien Enden überhöht ist, so dass der Bügel 82 (
Die Zähne ergeben mit dem Federbügel 82 zum einen ein gut wahrnehmbares Geräusch, wenn der als Stellrad ausgebildete Steller 70 gedreht wird. Weiterhin erzeugt der Federbügel 82 eine Rückstellkraft des Stellers 70, wenn der Steller 70 in diejenige Endposition gebracht ist, in der das Kreissegment 78 seine Überhöhung aufweist. Diese Position entspricht der maximalen Dampfmenge, z.B. für einen kurzen Dampfstoß ("Boostfunktion"), bei der die maximale Wassermenge in die Verdampferkammer 22 gelangt. Lässt der Anwender dann den Steller 70 los, bewegt bzw. dreht sich dieser durch Wirkung des Federbügels 82 und der zur Zahnreihe hin geneigten Flanke der Überhöhung automatisch in eine Stellung, die einer geringeren Dampfmenge entspricht.The teeth make with the

Claims (10)
- Steam iron (10) comprising a housing (12), an ironing sole (14) and a regulating device (30) for steam regulation, comprising a drip valve (32) connecting a water tank (20) with an evaporation chamber (22), wherein the drip valve (32) comprises a valve seat (36) fixed relative to the housing and a valve rod (34), which co-operates therewith and is axially displaceable between two extreme positions, with a valve axis (28), and a setter (70), with co-operates with the drip valve (32), for a steam quantity, wherein the setter (70) has a control surface (74) controlling movement of the drip valve (32) and the setter (70) is disposed in operative connection by its control surface (74) with a lever (50), which loads the valve rod (34) with pressure in dependence on a position of the control surface (74) with respect to an effective surface (52) of the lever (50), characterised in that the valve rod (34) has at its end facing the setter (70) a cap (44) with a valve effective surface (46) for operative connection with the lever (50), wherein the valve effective surface (46) is, for operative connection with the lever (50), formed as a slide surface on which the lever (50) slides transversely to the valve axis (28) when the valve rod (34) moves upwardly and/or downwardly.
- Steam iron according to claim 1, characterised in that the effective surface (52) of the lever (50) is arranged to be displaced adjacent to the valve rod (34).
- Steam iron according to claim 1 or 2, characterised in that the control surface (74) of the setter (70) displaces the effective surface (52) of the lever (50) parallelly to the valve rod (34).
- Steam iron according to any one of the preceding claims, characterised in that the setter (70) is constructed as a setting wheel.
- Steam iron according to any one of the preceding claims, characterised in that the setting wheel has an axis (80) of rotation arranged transversely to the valve axis (28).
