This object is achieved by a Dampfbügelsohlen device according to the invention with the features of claim 1 and a steam ironing device according to the invention with the features of claim 2. Preferred and advantageous design features of these devices according to the invention are the subject of the dependent claims, their support in the following description and the drawings Find.

The Dampfbügelsohlen device or Dampfbügelsohlen- assembly according to the invention, in particular a steam iron or a steam ironing station, has a sole plate with: steam outlet openings; a main evaporation chamber associated with a steam generating system, into which evaporation liquid, in particular water, can be introduced at a predetermined first location and which is in (steam) communication with the steam outlet openings; a sub-vaporization chamber associated with a steam surge system, into which vaporization liquid is introduced at a predetermined second location other than the first location; a heating device, in particular an electric heating device, for heating the sole plate and / or the evaporation chamber and / or the secondary evaporation chamber; and a temperature sensor mounting portion for mounting a temperature sensor for (directly or indirectly) detecting a temperature of the sole plate and / or the heater. The secondary evaporation chamber has a (in particular elongated) steam discharge duct which extends at least from the secondary evaporation chamber or the second location extends to the temperature sensor mounting portion. In at least one variant according to the invention, the steam discharge duct can also extend further, as will be explained below.

The soleplate preferably includes a soleplate and a lid which closes the soleplate. The secondary evaporation chamber is preferably immediately adjacent to the heating device, in particular the secondary evaporation chamber is preferably arranged directly above the heating device, which is usually integrated in the soleplate. The heating means preferably forms an essential part of the steam generating system and / or the steam jet system, or vice versa. The temperature sensor mounting portion is preferably arranged in or in the region of the main evaporation chamber. In particular, the temperature sensor mounting portion may be disposed directly on the sole plate or on the lid which closes the sole plate.

The steam ironing device according to the invention, in particular a steam iron or a steam ironing station, is provided with: a soleplate with steam outlet openings; a steam generating system and a main evaporating chamber into which evaporating liquid is introduced at a predetermined first position and which is in (steam) communication with the steam outlets; a steam impingement system and a sub-evaporation chamber into which evaporative liquid can be introduced at a predetermined second location other than the first location; a heating device for heating the soleplate and / or the evaporation chamber and / or the secondary evaporation chamber; and a temperature sensor for (directly or indirectly) detecting a temperature of the soleplate and / or the heating device. The sub-vaporization chamber has a (particularly elongated) steam blast conduit extending at least from the sub-vaporization chamber and the second location to the temperature sensor and its attachment portion, respectively.

The steam generating system and the steam blast system may be combined into a single system or unit. The steam generating system provided for the normal steam ironing operation can also be at least - A -

partially act as a steam blast system, and vice versa. The steam generation system and the steam injection system can also be configured as separate systems.

The temperature sensor is preferably arranged in the region of the main evaporation chamber. The temperature sensor preferably belongs to a temperature control system which has a temperature setting element for setting or predetermining a fixed or variable (steam) ironing temperature. The temperature control system expediently has a temperature controller for regulating a predetermined (steam) ironing temperature. The temperature sensor is preferably attached to the inside or outside of a lid which closes the soleplate of the soleplate. Here, a fastener, e.g. a screw or a rivet, projecting through the lid and connected to the temperature sensor mounting portion of the sole plate. The temperature controller and the temperature sensor and e.g. also the temperature adjusting element can e.g. Be part of a thermostat.

The volume and / or free passage cross-sectional area of the steam impingement duct is preferably small relative to the volume and / or cross-sectional area of the sub-evaporative chamber.

The inventors have recognized that, in conventional steam iron sole devices or conventional steam ironing devices, the loss of power of a steam pulse in a repeated use of the steam pulse function is due to the fact that the heating device is characterized by the evaporating liquid to be evaporated in a short time, especially in the steam cycle Area of the secondary evaporation chamber cools down quickly, the temperature sensor or the thermostat, however, this change in temperature is not detected quickly enough. Rather, a relatively long time elapses until the temperature sensor detects the cooling and activates the heating device via the temperature control system or increases the heat output of the heating device and reheats the soleplate and in particular its secondary evaporation chamber.

In the devices according to the invention, the steam discharge duct does not only function as a pure transport line for the one generated in the secondary evaporation chamber Steam used for the steam blast, but also as a kind of "fast" signal line for the temperature sensor, especially if the temperature sensor is located farther away from the sub-evaporative chamber.

If a steam pulse is carried out with the steam iron according to the invention, then a predetermined amount of water is introduced at the second point into the secondary evaporation chamber and evaporated there. Due to the so-called Leidenfrost effect, however, not the entire amount of water is immediately evaporated. Rather, there is a time-prolonged change in the state of matter of the water. Water drops dance, float or slide on a vapor cushion over the surface of the sub-evaporation chamber and the steam duct and are partially entrained with the steam. In this way, even water droplets or still unvaporized water pass through the steam jet duct to the temperature sensor mounting portion or along and influence the temperature sensor arranged there. At the same time, walls of the steam jet duct which (e.g., integral with other soleplate areas) are made of a highly thermally conductive material, e.g. an aluminum alloy, as a thermal conductor leading to the temperature sensor. Therefore, although the temperature sensor is mounted remotely from the sub-evaporation chamber and the second location, it becomes a cooling of the heating means, by the introduction of water into the sub-evaporation chamber and the evaporation of this

Water is generated for the purpose of generating a steam blast, capture immediately.

Thus, in addition to its steam line function, in the case of a steam pulse the steam-steam duct allows the temperature sensor to be supplied with a measured object more quickly for the purpose of determining a temperature measured value. This in turn ensures a faster reaction time of the temperature sensor with regard to temperature changes or cooling of the soleplate and its secondary evaporation chamber, or the heating device, caused by the surge of steam. Since the duct is at least from the secondary evaporation chamber or the second point, in / at which the evaporation liquid is introduced to generate a steam pulse extends to the temperature sensor mounting portion or to the temperature sensor, the temperature sensor or temperature controller or thermostat Temperature changes or cooling, which are caused in the steam shock mode, capture much faster than a conventional soleplate.

Even if the steaming function of the iron is repeatedly used, the temperature sensor or the thermostat can detect and transmit any temperature changes, in particular a reduction in the temperature of the heating device in the area of the secondary evaporation chamber, much faster than in the prior art the associated temperature control system to activate the heating device accordingly faster and reheat the soleplate and in particular their secondary evaporation chamber immediately. In the apparatus of the present invention, the evaporation liquid or water may be introduced into the secondary evaporation chamber associated with the steam injection system substantially at the same position as in a prior art apparatus, but the invention is not limited to such embodiment ,

The solution according to the invention makes it possible for the next steam burst or for a plurality of short successive bursts of steam a sufficiently high Heizbzw. Provide heat output, which evaporates the evaporation liquid for the next steam blast quickly and effectively, without this leading to a loss of power of the steam blast. The solution according to the invention therefore also makes it possible to generate repeated or short successive bursts of steam at constant power.

Due to the very effective, steam-related evaporation behavior of the devices according to the invention, it is also possible in principle, the

Pump capacity of a pump, which is used for introducing the evaporation liquid in the secondary evaporation chamber (and possibly also in the main evaporation chamber), to increase significantly compared to the prior art. For example, it is also possible to use a pump with a larger or much larger pump piston diameter than in previously known devices. Thus, the intensity of the steam pulse can be further increased by increasing the amount of water introduced into the secondary evaporation chamber. An advantageous embodiment of the devices according to the invention provides that the secondary evaporation chamber is open to vapor (but preferably largely liquid-tight) connected to the main evaporation chamber. So there is a vapor connection between the secondary and the main evaporation chamber. The vapor-open compound may preferably be prepared via the vapor line channel. This embodiment makes it possible in particular to use the regular steam outlet openings of the soleplate, which are used in the normal steam ironing operation, as steam ejection outlets. The aforementioned substantially liquid-tight connection can be achieved, for example, by thresholds, steps or the like, over which the steam can flow away, but which represent a barrier to liquid up to a certain level.

In a further preferred embodiment variant, the secondary evaporation chamber is isolated from the main evaporation chamber or separated in a vapor-tight manner. Thus, there is no vapor communication between the main and sub-vaporization chambers in this design. This variant is particularly suitable for constructions in which preferably at least one opening in the soleplate, which is separate from the regular steam outlet openings, acts as a steam ejection outlet opening. Since the steam generated in the secondary evaporation chamber is not conducted to an outlet opening via the main evaporation chamber, but rather from the secondary evaporation chamber via preferably the steam pulse.

Conduit directly into the at least one separate steam burst outlet opening, a particularly strong or powerful steam blast can be generated, the power remains constant or largely constant even with repeated or short successive operation of the steam injection system.

In particular, it is also provided that the temperature sensor can be mounted in or in the region of the main evaporation chamber. For example, the temperature sensor may be disposed above a sole plate portion of the main evaporation chamber or on a lid closing the sole plate including its main evaporation chamber or directly in the main evaporation chamber.

In the variant in which the secondary evaporation chamber is vapor-openly connected to the main evaporation chamber, it is preferred that the temperature sensor on an outlet region of the steam guide channel, where it opens into the main evaporation chamber, can be attached. Appropriately, then a corresponding temperature sensor mounting portion is provided at the soleplate at this point. This design makes it possible to detect temperature changes of the soleplate as a result of a steam pulse faster and at the same time to use the temperature sensor for detecting a temperature in the main evaporation chamber. The temperature sensor can thus perform an advantageous dual function.

In yet another preferred embodiment of the device according to the invention, the temperature sensor can be attached to a separation point or to a transition region of the main evaporation chamber and the secondary evaporation chamber (including its steam jet conduction channel). Appropriately, then a corresponding temperature sensor mounting portion is provided at the soleplate at this point. In this way, a single temperature sensor can be used for both chambers, and the sensor still detects very sensitively and rapidly a temperature change caused by a shock of steam / cooling of the soleplate or the heating device itself, which consists of an introduction of evaporation liquid in the secondary evaporation chamber results, as well as temperature changes in the region of the main evaporation chamber or on the soleplate itself. The separation point itself can, for example by a

Partition wall or a separation surface between the main and secondary evaporation chamber or its steam jet passage or the steam jet duct and the temperature sensor mounting portion may be formed.

In a further preferred embodiment of the devices according to the invention, a fastening section is provided for arranging a main temperature sensor of a temperature regulator assigned to the main evaporation chamber; and a fixing portion for arranging a sub-temperature sensor of the temperature controller; wherein the steam blast duct extends at least from the sub-vaporization chamber and the second location, respectively, to the attachment portion for disposing the sub-temperature sensor. This variant is particularly suitable in the case of using a temperature controller associated with the heating device, which has at least two temperature sensors, namely one for the Main evaporation chamber and one for the sub-evaporation chamber or its steam jet duct.

In particular, the temperature controller may have a main temperature sensor located in or near the main evaporation chamber and a sub-temperature sensor; wherein the steam jet conduit extends at least from the sub-vaporization chamber and the second location, respectively, to the sub-temperature sensor. Preferably, the secondary temperature sensor in the region of the secondary evaporation chamber, in particular in the region of the steam jet duct, attachable.

The temperature sensor used in the context of the devices according to the invention may in particular comprise a bimetallic element, which may be e.g. is used for direct or indirect operation of a switch for activating and deactivating an electric heating device. However, in principle, electronic sensors, e.g. NTC sensors or the like, possible.

Yet another preferred embodiment of the devices according to the invention provides that the vapor-tight separated from the main evaporation chamber secondary evaporation chamber via the steam discharge duct with at least one separate steam injection outlet opening, in particular one of the

Steam outlet openings isolated or vapor-tight separate separate steam injection outlet opening, is connected. This has the advantage that in the case of a steam pulse, the steam is then passed directly and without detour via the main evaporation chamber through the steam discharge duct to the at least one separate steam discharge port and ejected there. The functions of the steam impulse

Conduit channels with respect to the temperature sensor mounting portion and temperature sensor are in this case the same as previously explained. Thus, even with repeated and rapidly successive bursts of steam each a constant burst of steam can be generated with a very high steam output or intensity.

In this context, it has also proved to be advantageous to arrange the at least one separate steam ejection outlet opening in a front region of the soleplate, in particular in the region of the tip of the soleplate. Thus, constant High intensity steam bursts are provided on a portion of the soleplate which are most commonly used for steam ironing complex or hard to reach areas of the ironing stock which areas require high steam blast performance.

In the devices according to the invention, the secondary evaporation chamber or the second location is preferably arranged in a front portion of the soleplate; and the temperature sensor is preferably attachable in a rear portion of the soleplate. In this way, the second point at which evaporation liquid for generating a steam pulse is introduced can be positioned near the first location. At the first location, which is also usually located in a front portion of the soleplate, the evaporation liquid is introduced for a normal steam ironing operation. This makes it possible, in particular, to use the same pump to introduce evaporation liquid into the main and secondary evaporation chamber and to lay only short supply paths. By mounting the temperature sensor in a rear portion of the soleplate, basic constructions of conventional soleplates may also be used in which the temperature sensor is usually located in this area; and only minor structural adjustments are required to achieve the advantages of the invention.

According to the invention, a preferred embodiment is also provided in which the steam jet duct has an asymmetrical shape. In particular, this shape may serve to achieve a particular piping of the steam impingement duct with respect to the main and subvaporizing chambers as well as the regular steam outlets and the at least one steam blast outlet.

The steam jet duct can also be formed in a labyrinth or meander shape. Such a steam jet duct can then also have several adjacent channel sections. In this way, not only a streamlined arrangement of the steam impingement duct in relation to the main and Nebenverdampfungskammer and the steam outlet openings and the at least one steam burst outlet opening can be achieved, but it is also possible with different channel sections different areas of individual temperature sensor or different temperature sensors or their detection ranges to achieve. This may be used in conjunction with a temperature control system and the heater to achieve a particular response of the heater in the event of steam bursts or to achieve a particular heater response in the event of steam bursts and / or in the case of a regular steam ironing operation.

In at least another preferred embodiment of the invention, the sub-vaporization chamber is located at a first side region of the main vaporization chamber and / or the soleplate; and the steam impingement duct extends from the sub-evaporation chamber and the second location toward the back of the soleplate and along the temperature sensor and along the temperature sensor mounting portion, and then toward the front or tip of the soleplate and around the Front of the main evaporation chamber around to an opposite side region of the soleplate. There, the steam discharge duct in at least one variant of the invention can open into the main evaporation chamber. In another variant, it may also be closed at this point. This embodiment allows a particularly effective and structurally favorable arrangement of the evaporation chambers and the steam jet duct in the soleplate and relative to the steam outlet openings or relative to the at least one steam pulse.

Outlet. In addition, with such a construction, if necessary, several steam discharge openings can be supplied with steam, which are arranged at different positions in a front region of the soleplate. The steam jet duct can also be horseshoe-shaped or arcuate in particular. An opposite side region of the soleplate is to be understood as meaning both directly opposite and offset from one another.

The secondary evaporation chamber can be arranged in particular in the immediate vicinity of the temperature sensor mounting portion or in the immediate vicinity of the temperature sensor. Thereby, the steam jet duct can be made shorter; or the sub-evaporation chamber or a portion thereof may be formed in this area itself as a steam jet duct, and vice versa. The temperature sensor is therefore very responsive even in the case of repeated bursts of steam.

And finally, yet another preferred and advantageous embodiment of the invention provides that the sub-vaporization chamber and / or the vapor-jet conduit extend at least partially around the main vaporization chamber. In this case, the course of the steam jet duct can also be horseshoe-shaped or arcuate in particular. This allows a manufacturing technology and aerodynamically favorable and space-saving arrangement of said components in relation to the main evaporation chamber and relative to the regular steam outlet openings and the at least one steam discharge outlet opening of the soleplate.

Examples of preferred embodiments of the devices according to the invention with further advantages and details are described below with reference to the accompanying drawings and explained in more detail.

It shows:

Fig. 1 is a plan view of an open steam iron sole device of a steam iron according to the invention according to a first

embodiment; and

2 is a schematic plan view of an open Dampfbügelsohlen-

Device of a steam iron according to the invention according to a second embodiment.

The steam iron sole apparatus 2 or steam iron sole assembly shown in Fig. 1 used in a steam iron according to the invention has a soleplate 4 with a plurality of steam outlets 6. The steam iron is equipped with a steam generating system which is a central main evaporation chamber 8 is assigned, in the evaporation liquid (here: water) at a predetermined first point S1 can be introduced. The main evaporation chamber 8 communicates with the steam distribution channels 10 Steam outlet openings 6 in steam connection. The iron is further provided with a steam injection system associated with a secondary evaporation chamber 12 which is vapor-openly connected to the main evaporation chamber 8. In the illustration according to FIG. 1, the secondary evaporation chamber 12 is located laterally, to the left of the main evaporation chamber 8. In the secondary evaporation chamber 12, the water can be introduced at a predetermined second location S2, which is different from the first location S1 , As can be seen in the drawing, the first location S1 is located in a front and middle portion of the soleplate 4, while the second location S2 is located in a front, side portion of the soleplate 4 and laterally from the first location S1.

The iron or its soleplate 4 furthermore have a horseshoe-shaped electrical heating device 14 integrated in the soleplate 4 for heating the soleplate 4, the main 8 and the secondary evaporation chamber 12. The secondary evaporation chamber 12 and the second location S2 are also located just above a portion 14a of the electric heater 14. If water is introduced into the secondary evaporation chamber 12 for the purpose of generating a steam pulse, the water is therefore evaporated particularly rapidly.

In addition, the soleplate 4 has in its rear portion and at a lateral region of the main evaporation chamber 8 a temperature sensor

Attachment section 16 for mounting a temperature sensor (not shown). The temperature sensor mounting portion 16 between the temperature sensor is located at a separation point 20 formed by a portion of a partition wall 18 or at a transition region of the main evaporation chamber 8 and secondary evaporation chamber 12. The temperature sensor, for example comprising a bimetallic element, detects a temperature of Sole 4 and the heating device 14. The temperature sensor belongs to a temperature control system, not shown, which regulates the temperature, in particular a set (steam iron) temperature of the soleplate 4 and the heating device 14. This control system also includes an unillustrated temperature setting element, eg a rotary knob, for setting a desired (steam) ironing temperature. As further shown in Fig. 1, the sub-vaporization chamber 12 has an elongated burst port conduit 22 extending from the sub-vaporization chamber 12 to the temperature sensor attachment portion 16 and the temperature sensor attachable there.

The steam jet duct 22 has an asymmetric shape in this embodiment. In addition, the steam jet duct 22 is formed like a labyrinth or meander and has in the present case a partial area with two adjacent channel sections 22a, 22b. In the present example, the steam discharge duct 22 thus extends from the secondary evaporation chamber 12 or the second location S2 in the direction of the rear side of the soleplate 4 to the temperature sensor attachment section 16 or temperature sensor and along it. Further, the steam blast duct 22 extends through a loop or turn 24 (having an enlarged channel cross-section) then back toward the front or tip of the soleplate 4 and around the front of the main evaporating chamber 8. From there, the steam discharge duct 22 then extends to a side of the soleplate 4 opposite the secondary evaporation chamber 12 and there opens into the main evaporation chamber 8. The mouth is indicated by the reference numeral 26. In this example, the orifice 26 also provides the vapor-open connection between the secondary evaporation chamber 12 and the main combustion chamber.

Evaporation chamber 8 ago.

In a normal steam ironing operation, the water at the first location S1 is introduced into the main evaporation chamber 8 and evaporated. Water vapor thus passes through the main evaporation chamber 8 and the steam distribution channels 10 to the

Steam outlet openings 6 and exits there from the soleplate 4. Due to the steam ironing temperature changes and changes in temperature setting by a user can therefore be detected by the attached at the separation point 20 and the transition region of the main 8 and secondary evaporation chamber 12 temperature sensor safely. And the operation of the heating device 14 can be controlled or regulated via the coupled with the temperature sensor temperature control system. If a steam pulse is now carried out with the steam iron according to the invention, then a predetermined amount of water is preferably introduced only at the second point S2 into the secondary evaporation chamber 12 and evaporated there. Due to the so-called Leidenfrost effect, however, not the entire amount of water is immediately evaporated. Rather, there is a time-prolonged change in the state of matter of the water. Water drops dance, float or slide on a vapor cushion above the surface of the steam duct 22 and are partially entrained with the steam. In this way, even water droplets or still unvaporized water pass through the steam impingement duct 22 to the region of the temperature sensor mounting portion 16 and affect the temperature sensor arranged there. At the same time, the walls of the steam jet duct 22 made of a good heat conductive material act as a heat conductor leading to the temperature sensor.

Therefore, although the temperature sensor is mounted remotely from the sub-evaporation chamber 12 and the second location S2, the temperature sensor will promptly detect cooling of the heater 14 caused by the water-jetting introduced water vapor (particularly, in its sub-area 14a). And by the temperature control system coupled to the temperature control system, the heating device 14 can be readjusted or reactivated immediately to provide a sufficient temperature for evaporation of the water introduced for a subsequent or repeated burst of steam in the partial area 14a. Thus, repeated and rapidly successive bursts of steam of substantially constant intensity can be realized.

FIG. 2 shows a schematic plan view of a steam sole according to the invention.

Device 2 of a steam iron according to the invention according to a second embodiment. The components of this variant largely correspond to those of FIG. 1. A repeated description of identical or similar components will therefore be dispensed with, and only the essential differences from the first embodiment will be explained. In the variant according to FIG. 2, the secondary evaporation chamber 12 is completely isolated or vapor-tightly separated from the main evaporation chamber 8. There is thus no direct vapor connection or fluid connection between the main Evaporation chamber 8 and the secondary evaporation chamber 12. This is achieved in the present case, that in comparison to the variant of FIG. 1, the existing orifice 26 or opening to the main evaporation chamber 8 is completely closed (see in Fig. 2 with designated by the reference numeral 32). Thus, compared with the soleplate according to FIG. 1, only a very small modification is required in order to realize this variant of the steam-impingement duct 22, which is completely separated from the main evaporation chamber 8. Of course, the invention is not limited to such an embodiment. In the embodiment according to FIG. 2, the steam discharge duct 22 could end, for example, even in the region of the tip of the iron.

The main evaporation chamber 8 is in turn connected via steam distribution channels 10 with the steam outlet openings 6, from which steam exits only in a regular steam ironing operation. The soleplate 4 has at least one, separate in the front central region or in the region of the tip of the soleplate 4, separate steam ejection port 28 (or more), which is used only in the case of generating a steam pulse. This steam discharge outlet 28 is arranged in the present case in a small pre-chamber 30 and completely separated from the normal steam outlet openings 6. The steam-impingement duct 22 leads from the secondary evaporation chamber 12 to at least this separate steam-exhaust outlet opening or opens via an orifice 34 in the pre-chamber 30th

In the steam operation of the steam iron according to the invention, the water introduced at the second point S2 into the secondary evaporation chamber 12 is vaporized, and the water vapor immediately and without detour via the main evaporation chamber 8 to the at least one separate steam discharge outlet opening

28 headed and ejected there. The functions of the steam jet duct 22 with respect to the temperature sensor mounting portion 16 and temperature sensor are the same as in Fig. 1. In this way, a steam burst of particularly high intensity can be generated. Furthermore, due to the positive effects of the construction according to the invention already described in connection with FIG. 1, it is possible to maintain this high power of the steam pulse constant or substantially constant even with repeated and rapidly successive steam bursts. The invention is not limited to the above embodiments. Within the scope of protection, the devices according to the invention may, on the contrary, also assume other embodiments than those specifically described above. In particular, features of the individual embodiments can also be combined with each other.

The free passage cross-section of the steam jet duct can be constant over the extent thereof or else vary locally. The steam jet duct may also have bottlenecks, steps or thresholds that provide a liquid barrier. This barrier can be arranged, in particular, in a region of the steam-impingement duct, which follows the temperature-sensor-attaching section in relation to the extension starting from the secondary evaporation chamber.
