Description

Shirt ironer

FIELD OF THE INVENTION The invention relates to a shirt ironer.

TECHNICAL BACKGROUND

Shirt presses are useful household appliances nowadays to make everyday life easier. A shirt ironer usually includes an inflatable body over which a shirt can be pulled. Heated air is then applied to this body, which tightens and warms the shirt. As a result of the treatment, the shirt is then significantly smoothed, or in other words, ironed. Some of the corpses of today's shirt ironers have air outlet openings in areas that are usually covered by the shirt during operation. This means that heated air can be applied directly to the shirt.

State-of-the-art shirt presses are therefore suitable for applying heated, essentially dry air to the shirt. If the shirt has already dried before treatment with the shirt ironer and it may already have wrinkles, for example because it was lying in a pile of laundry to be ironed, the smoothness (wrinkle-free) of the shirt that can be achieved by treatment with the shirt ironer is limited. This is because wrinkles that have formed in the fabric that has already dried can generally only be insufficiently compensated (eliminated) by dry, heated air. SUMMARY

It is an object of the invention to eliminate or at least reduce the disadvantages of known shirt pressers.

The object is solved by the subject matter of the independent claim.

Confirmation copy A shirt ironer is provided which includes a blower and an inflatable doll. An outlet of the fan opens into an interior (an interior, an interior volume delimited by corresponding exterior walls) of the doll. The shirt ironer also comprises a first reservoir and at least one first heating device. The first reservoir can be filled with a liquid (usually water). In a first operating state, the water can be heated in such a way by means of the first heating device and the doll can be inflated in such a way by means of the blower that a shirt pulled over the doll can be acted upon by water vapor conveyed by the blower. The blower, the first heating device and the first reservoir can be arranged such that an air flow (suction effect) can be generated by the blower and that as a result of the air flow (suction effect) the rising water vapor is transported in accordance with the air flow, in particular in an interior of the doll is distributed. The fan can therefore only interact “indirectly” with the first heating device and the first reservoir. The operative connection of the first reservoir with the first heating device can essentially correspond to the structure and / or the functioning of a kettle. The doll can therefore be permeable to air and / or water (steam). This means that the shirt can be exposed to moist air (essentially saturated water vapor). In this way, the quality of the smoothing process can be advantageously increased, since folds of the shirt can be compensated more effectively with humidified air. As a result, the quality of the ironing process is advantageously improved over the effects of shirt pressers according to the prior art.

The first reservoir can have a volume V, for which the following applies: 100 ml s V <5000 ml, advantageously 300 ml <V £ 2000 ml, further advantageously 500 ml <V s 1000 ml, further advantageously V can be substantially 750 ml. With a complete vapor deposition of a shirt, an amount of water VB of essentially 350 ml can be consumed.

The first heating device can have a heating output HeizPI, for which the following applies: 100 W s HeizPI <5000 W, advantageously 1000 W s HeizPI 5 2500 W, further advantageously 1500 W <HeizPI <1750 W, further advantageously essentially HeizPI = 1600 W. The application of the shirt pulled over the doll with water vapor conveyed by the blower during the first operating state can be achieved within a time interval t1, for which the following applies: 1 min <t1 s 20 min, advantageously 3 min s t1 £ 12 min, further advantageously 5 min <t1 s 10 min, further advantageously essentially t1 = 7 min.

Thus, the volume of the first reservoir can advantageously be sufficient to charge several shirts with moist, heated air, or sufficient to carry out the treatment several times, in particular at least twice, in accordance with the first operating state. Advantageously, the reservoir does not necessarily have to be refilled after each treatment. In addition, the heating power of the first heating device can advantageously be sufficient to generate substantially saturated water vapor, that is to say to modify the relative atmospheric humidity of the air conveyed by the blower in such a way that it is above 50%, in particular above 70%, further particularly above 85 % lies.

The shirt ironer can be set up in such a way that the duration of the time interval t1 of the first operating state, in which the shirt pulled over the doll is acted upon by water vapor conveyed by the blower, is variable. The duration of the time interval t1 can thus include a first time interval in the first operating state. In an alternative first operating state, the duration of the time interval t1 * can, however, comprise a second time interval that is different from the first time interval, ie t1 * ^ t1. The duration of the first operating state in which the shirt drawn over the doll is acted upon by water vapor conveyed by the blower can depend in particular on the amount of water in the first reservoir.

The shirt ironer can include a level detection functionality that can detect the level of the first reservoir. In addition, the shirt ironer can include a control functionality that determines the length of time required for the shirt to be adequately supplied with water vapor based on the determined fill level. In this way, sufficient supply of steam to the shirt can advantageously be ensured even with different fill levels of the first reservoir. A higher fill level of the first reservoir may require that the first time interval t1 to apply steam to the shirt is longer than with a lower fill level of the first reservoir. In other words, a time interval of essentially t1 = 7 minutes can be sufficient to moisten the shirt when the filling level is essentially 350 ml. However, if the fill level is essentially 700 ml to 750 ml, a time interval t1 * may be necessary to apply sufficient steam to the shirt, for which the following applies: t1 *> t1. In this way, the shirt ironer is advantageously set up to implement different durations of the first operating state. In particular, an optimal result of the moistening of the shirt can thus be guaranteed even with a variable fill level of the first reservoir.

The shirt ironer can also be set up in such a way that a user makes a preselection based on the fill level and that the shirt ironer makes the duration of the first operating state, in particular the steaming of the shirt with water vapor, as a function of the user's pre-selection. Thus, the shirt ironer can be set up, even without fill level detection functionality, to select the steaming period in spite of the variable fill level of the first reservoir in such a way that the shirt pulled over the doll is sufficiently steamed.

The shirt ironer may further include a second heater. In a second operating state, heated but essentially dry air can be applied to the shirt. This is helpful for the ironing process if the shirt has already been moistened during the first operating state or if it is moist for other reasons. For example, it may have been moistened manually, or it may have been removed from the washing machine with residual moisture and pulled over the doll. Additional humidification according to the first operating state can then be unnecessary. The second operating state is therefore advantageously set up in such a way that a shirt pulled over the doll is no longer moistened.

The first reservoir can be connected to the interior of the doll by means of a circumferential gap. As a result, the shirt can be subjected to the water vapor essentially uniformly. The circumferential gap advantageously allows that essentially All parts of the shirt can be supplied with humidified air, so that the entire shirt can be smoothed.

The shirt ironer can have a fall sensor. The fall sensor can be set up to detect a fall and / or an inclination above a first limit value of the shirt ironer. The first heating device and / or the blower and / or the shirt ironer can be switched off as a result of detection of a tipping over and / or an inclination of the shirt ironer above a first limit value. Alternatively, as a result of the detection, operation of the shirt ironer in the first operating state can also be prevented, for example by means of a blocking function which prevents commissioning. In addition, the shirt ironer can be set up to output a first warning signal as a result of the detection. Thus, the shirt ironer can advantageously have a safety mechanism that can ensure the detection of an operating position that is not provided, and which consequently regulates and / or prevents the operation of the shirt ironer in order to avoid damage.

The shirt ironer may include an overheating sensor. The overheating sensor can be set up to detect overheating of the shirt ironer and / or an insufficient fill level of the first reservoir below a second limit value. As a result of the detection, the first heating device and / or the blower and / or the shirt ironer can be switched off. Alternatively, operation of the shirt ironer in the first operating state can be prevented as a result of the detection. In addition, the shirt ironer can be set up to output a second warning signal as a result of the detection. The second warning signal can be the same as the first warning signal. The first and the second warning signal can also be different from one another. Thus, the shirt ironer can advantageously have a further security mechanism which can ensure the detection of an operating state not provided for and which consequently regulates and / or prevents the operation of the shirt ironer in order to avoid damage.

The shirt ironer can have a moisture degree functionality. The duration of the first operating state can depend on the moisture degree functionality. The shirt ironer can advantageously be set up so that a degree of moisture the shirt of the shirt ironer can be preset and / or selected and / or detected. A duration of the first operating state can depend on the moisture degree functionality, or on the corresponding setting, or on the corresponding measured value. Thus, the shirt ironer can advantageously take into account a (residual, or adjusted or measured) moisture level of the shirt when the shirt pulled over the doll is applied, so that the shirt is not over-moistened.

The shirt press can include a program selection function. The program selection function can be set up in such a way that either the first operating state or the second operating state or a combination of the first and the second operating state can be selected. This advantageously enables the user to choose between different operating states, for example because the user wishes that the shirt is not additionally moistened (in a generally possible first operating state).

The shirt ironer can be set up in such a way that the first heating device and the second heating device cannot be operated simultaneously. As a result, the shirt ironer can advantageously be set up so that an instantaneous power consumption is reduced. The reduction occurs at least compared to a hypothetical state in which both heating devices would be operated simultaneously. The total power consumption of the shirt ironer in the first operating state can be a power P1, for which the following applies: 100 W <P1 <5000 W, advantageously 1000 WS P1 s 3000 W, further advantageously 1750 W <P1 s 2250 W, further advantageously essentially P1 = 2000 W. The total power consumption of the shirt ironer can be a power P2 in the second operating state, for which the following applies: 100 W s P2 s 5000 W, advantageously 1000 W <P2 <3000 W, further advantageously 1500 W <; P1 £ 1800 W, further advantageously essentially P2 = 1600 W. As a result, the shirt ironer can advantageously be set up in such a way that lower demands are placed on the electrical line and supply technology to be used.

The manikin may include a torso section and inflatable arms extending from the torso section. The inflatable arms extending from the torso section can be tucked into the shirt's sleeves. The shirt and sleeves can then be blown with air conveyed by a blower and / or conveyed water vapor. The shirt ironer can thus advantageously be set up in such a way that both the body parts of the shirt and the sleeves can be moistened and / or smoothed and / or dried and / or ironed.

The doll can be at least partially breathable. For this purpose, the doll's wall can have at least one perforation, a hole, an air outlet, a slot, or the like. include. The air permeability of the doll's wall can also be provided by an adapted stitch density or thread density of the underlying fabric of the doll's wall. In other words, the air permeability of the doll wall can be an intrinsic property of the textile fabric on which the doll wall is based.

The doll can comprise a doll's wall (wall), wherein different wall sections can have areas of different air permeability. The interior or an internal volume of the doll is defined by the doll's wall. Due to the different air permeability of the different areas of the wall of the doll, different areas of the shirt pulled over the doll can be acted upon with air of different intensities. A more uniform result of moistening and / or drying and / or ironing different sections of the shirt can thus be achieved.

The different air permeability of the doll in regions of higher air permeability is preferably produced by holes cut into the tissue, in particular wherein the holes have a diameter of at least 1.5 mm.

According to one aspect, the wall of the doll in the area of the inflatable arms is made increasingly air-permeable with increasing distance from the trunk.

The temperature at the surface of the doll is preferably between 40 ° C. and 95 ° C., more preferably between 60 ° C. and 90 ° C., at least in the second operating state. The highest temperatures prevail at the openings in the trunk area of the doll. The wall of the doll may have areas with greater air permeability in the sections of the sleeves of the shirt and / or adjacent to a button placket of the shirt. This configuration makes it possible, particularly those areas of the shirt which have a denser textile structure (increased thread density) (for example the button placket or the breast pocket) to act more intensively on air conveyed by the blower than other areas. This can further improve the uniformity of the result of the moistening and / or drying and / or ironing of different sections of the shirt.

Areas with higher air permeability can have or have at least twice as large air permeability as the areas of the wall with lower air permeability. This can further improve the uniformity of the result of the moistening and / or drying and / or ironing of different sections of the shirt, even if the textile structure (thread density) of the different areas of the shirt is very different.

The shirt ironer can have at least one adjustment unit. A circumference of the fuselage section can be changeable by the adjustment unit, for example a mechanical adjustment unit. As a result, the shirt presser's doll can advantageously be adapted to different shirt sizes, so that the ironing quality can be guaranteed regardless of the shirt size.

According to a preferred embodiment, when the adjustment unit is set with a minimal trunk circumference, the wall forming a trunk section has an internal fold. Excess material from the fuselage section is led into the interior of the doll. This prevents the excess material from causing wrinkles in the shirt.

According to a preferred embodiment of the invention, the adjustment unit is formed by at least one zipper and / or a button strip. As a result, the circumference of the torso section can be easily and quickly adapted to different shirt sizes. The adjustment unit can also be partially or entirely formed by a lacing. Two adjacent adjustment units can be provided in the area of the front of the fuselage section and / or in the area of the rear of the fuselage section.

The shirt ironer can have an essentially vertical stand, in particular a telescopic stand. At its upper end, at least one shoulder strap projecting laterally can be provided. The shoulder strap can have air outlet openings. As a result, the shirt ironer can advantageously be set up in such a way that the shoulder area (which usually has a modified textile structure) can also be acted upon by air conveyed by a blower.

The shirt press can include a base part. At least the first heating device and the blower can be arranged in the base part. The second heating device can also be arranged in the base, in particular in the form of a heating coil. The second heating device can functionally interact with the blower, in particular the heating coil can therefore be arranged in the blower. This means that the blower can have a cold air blower functionality when the second heating device is deactivated and a warm or hot air blower functionality when the second heating device is activated. In this context, a “cold air blower” refers to a blower that includes a deactivated integrated heating device and a warm or hot air blower to a blower that includes an activated integrated heating device. Of course, heated water vapor can be conveyed by the blower in a cold air blower functionality (or by an air flow / suction effect generated by the blower), which is why it still functions as a cold air blower, since the blower does not actively increase the temperature (similar to a modern hair dryer with a cold blower function ). In contrast, a “warm air blower” can be understood to mean a blower that comprises a heating device in such a way that the sucked-in air is actively heated (similar to a modern hair dryer with a warm blower function). The base also includes the first reservoir and thus also the first volume. The fact that (almost) all of the weight-relevant components are arranged in the base advantageously ensures that the shirt ironer has a low center of gravity and therefore assumes a secure stand. In particular, there is or is an adjustable timer and / or a display device by means of which the duration of the first operating state and / or the duration of the second operating state can be set or the course of the first operating state and / or the second operating state is displayed.

A method of smoothing (ironing) a shirt is also provided. The method may include placing a shirt over an inflatable, at least partially air-permeable doll. In a first operating state, the method can further include generating an air flow of conveyed water vapor within the manikin, such that the shirt pulled over the manikin is acted upon by the conveyed water vapor, so that the shirt is moistened and smoothed.

In an additional second operating state, the method can further include applying an air flow of warm (hot) but essentially dry air to the shirt, so that the shirt is moistened, dried, smoothed and ironed.

The method can also include providing the air flow of conveyed water vapor by heating an amount of water located in a first reservoir with the aid of an air flow-generating fan, in particular the heating being carried out by means of a first heating device.

Further aspects of the method result logically from the aspects shown in relation to the device.

BRIEF DESCRIPTION OF THE FIGURES

Further advantageous aspects result from the following description of preferred exemplary embodiments with reference to the drawings, in which:

1 is a simplified schematic representation of the shirt ironer,

Fig. 2 is a simplified schematic representation of the shirt ironer with the doll hidden, and - Fig. 3 is a simplified schematic cross-sectional view of part of the base of the shirt iron.

DETAILED DESCRIPTION OF THE FIGURES

FIG. 1 shows a simplified schematic illustration of the shirt ironer 100. The shirt ironer 100 comprises a base 1 10. The base 110 comprises a base 1 12 by means of which the shirt ironer 100 can be securely held on the floor. The base 1 10 further comprises an operating and display part 1 14. The operating and display part 1 14 is set up to display various operating states of the shirt ironer 100. Furthermore, 14 different operating states of the shirt ironer 100 can be set or selected by means of the operating and display part 1. The shirt ironer 100 further comprises a doll 200 which is arranged above the base 110. The doll 200 is partially carried by a neck member 192. The doll 200 comprises a torso area 210 and two sleeves 212, 214. The doll 200 has a fabric wall (doll wall) 201, which is perforated, perforated, slotted, or the like. 202 is enforced. The doll wall 201 is therefore or at least partially permeable to air due to the nature of the fabric forming the doll wall. Neck member 192 is generally located at the end of a telescopic rod 180 (a telescopic stand) (see Figure 2). The length of the telescopic rod 180 can be changed. The doll 200 also has at least one mechanical adjustment unit 216, by means of which a circumference of the doll 200 can be changed. The mechanical adjustment unit 216 can be a zipper or a button strip, for example. The telescopic rod 180 and the adjustment unit 216 make the doll 200 adaptable to different shirt sizes.

The shirt ironer 100 is set up to receive a shirt or is set up to pull a shirt over the doll 200. The doll 200 can have suitable clamping mechanisms or buttons or the like on the ends of the sleeves 212, 214. so that the sleeves of the shirt pulled over the doll 200 can be fixed in these places. Furthermore, the base 110 of the shirt ironer 100 has suitable clamping mechanisms, buttons, or a clamping gap, so that the shirt hem of the shirt pulled over the doll 200 can be fixed there. If the button placket of the shirt is closed, then thereby affixing the shirt relative to the doll 200 and neck member 192, which mimics the neck of a human neck. Weights can also be provided which are attached to the sleeves and / or the hem of the shirt to hold the shirt in position.

The shirt pulled over the doll 200 has areas with different thread densities. For example, the thread density is usually increased in the areas of the button facing, the sleeves and the saddle. Therefore, the doll also has 200 areas of different hole densities. In particular, the hole density is increased in those areas in which the thread density of the shirt pulled over the doll 200 is increased. This is indicated schematically in Figure 1.

FIG. 2 shows a simplified schematic illustration of the shirt ironer 100, the doll 200 being hidden. The base 1 10 comprises a cover 120. The cover 120 comprises an outer edge 122. The outer edge 122 of the cover 120 is bordered at a small distance from a border 1 16, which is formed by the side wall 1 15 of the base 1 10. The spacing of the border 116 relative to the outer edge 122 forms an annular gap 124 (circumferential gap). The annular gap 124 is formed around the entire cover 120. The lid 120 further includes a flap 126 that can be opened. A ventilation grille 130 protrudes from the cover 120. The ventilation grille 130 forms the outlet for a fan 144, which is arranged below the ventilation grille 130.

The shirt ironer 100 further comprises a telescopic rod 180, at the upper end of which a shoulder strap 190 is arranged. The shoulder strap 190 comprises the neck element 192, which is modeled on the neck of a human. The shoulder strap 190 also includes two protruding cantilevers 194, 196, which essentially replicate a person's shoulder support surfaces. The neck element 192 and the arms 194, 196 have air outlet openings 193, 198. The air outlet openings 193 and 198 are coupled to the fan 144. The neck element 192 and the extensions 194, 196 are therefore arranged in such a way that the shoulder areas of the shirt pulled over the doll can be arranged according to their natural shape. Below the flap 126, the base 110 comprises at least one first reservoir 140. The flap 126 can be opened in order to fill the first reservoir 140 with water. In the base 110 there is also at least one first heating device 142 in the form of a cylinder, a plate, or the like. arranged which extends vertically upward beyond the lowest level 147 of the first reservoir 140. The first heating device 142 can be used to heat water located in the first reservoir 140. The operative connection of the first reservoir 140 with the first heating device 142 can thus essentially correspond to the structure and / or the functioning of a kettle. The resulting water vapor can then escape through the annular gap 124 from the base 110 into the doll 200 on all sides. Since the water vapor is at an elevated temperature, it will generally rise within the doll 200. With the help of perforations, holes, slits, etc. 202 the shirt pulled over the doll 200 is exposed to the water vapor. The areas of different hole densities of the doll 200 ensure that the shirt is exposed to the water vapor substantially uniformly in accordance with the areas of different thread densities.

The annular gap 124 has a surface A which is sufficient to enable a sufficient throughput of the water vapor. The surface A of the annular gap 124 can be dimensioned as follows: 500 mm ² <A <20,000 mm ² , advantageously 1000 mm ² ί A ί 10,000 mm ² , further advantageous

2000 mm ² <A i 6000 mm ² , further advantageous 3000 mm ² £ A <4000 mm ² . This ensures that a sufficient amount of water vapor can escape from the base 110 into the doll 200 and is available for moistening the shirt.

To further improve the distribution of water vapor, the fan 144 can be used to generate an air flow. The air flow originates from the ventilation grille 130 and is directed essentially vertically upwards in the direction of the shoulder strap 190, so that the air flow transporting the water vapor ensures an improved distribution of the water vapor up to the shoulder area and the sleeves of the shirt. The shirt ironer 100 can also be set up in such a way that the air flow of the fan 144 also exits the air outlet openings 193, 198. The blower 144 includes a second heater 152 that is different from the first heater 142 and is separated. The blower 144 can therefore act as a cold air blower when the second heating device 152 is deactivated and as a warm or hot air blower when the second heating device 152 is activated. In order to promote the water vapor generated, the fan 144 can act as a cold air fan according to a cold air function, so that a power saving can advantageously be achieved due to the deactivated second heating device 152.

If the fan 144 acts according to a warm air function as a warm air fan, an air flow of heated and essentially dry air is generated. This flow of warm air is passed into the doll 200, the airflow being able to be applied to the shirt pulled over the doll 200 with the aid of the perforations, holes, etc. Thus, the essentially dry, hot air can escape from the ventilation grille 130 into the interior of the doll 200 and then hit the shirt through the holes 202. Thus, the shirt pulled over the doll 200 can be effectively dried by the fan 144 generating a warm air flow.

The procedure for smoothing (ironing) a shirt is outlined below using the chronological sequence. First, a shirt is pulled over the doll 200 in the manner previously illustrated. In a first operating state BZ1 of the shirt ironer 100, water which is stored in the first reservoir 140 is first heated using the first heating device 142. Subsequently or simultaneously, the blower 144 is activated in a cold air functionality, so that the doll 200 is inflated and the shirt pulled over the doll 200 is stretched. Since the water vapor generated is transported by the air flow, this air flow is conducted through the annular gap 124 into the interior of the doll 200. Since the doll 200 is at least partially permeable to air, the shirt is therefore exposed to the water vapor and moistened. The operating state BZ1 is set up in such a way that the shirt can be moistened in a time period t1 for which the following applies: 1 min £ t1 s 20 min, advantageously 3 min ^ t1 s 12 min, further advantageously 5 min £ t1 s 10 min , further advantageously essentially t1 = 7 min. The first heater 142 is then switched off. As a result, the shirt pulled over the doll 200 is moistened and smoothed.

The hot air functionality of the fan 144 is then activated in a second operating state BZ2, ie it becomes the second Heater 152 activated. The shirt is dried, smoothed and ironed by the essentially dry and warmed air, which is now applied to the shirt from inside the doll 200. The initial moistening of the shirt improves the ironing result of the shirt. The shirt ironer 100 is thus set up in such a way that even pronounced folds in the shirt can be compensated for, for example due to storage in a stack of laundry, and a uniform appearance of the shirt can be achieved.

The shirt ironer 100 comprises a voltage supply unit which provides a supply voltage for the various electrical components. The total power consumption of the shirt ironer 100 can be a power P1 in the first operating state BZ1, for which the following applies: 100 W <P1 S 5000 W, advantageously 1000 W <P1 s 3000 W, further advantageously 1750 W <P1 <2250 W, further advantageously essentially P1 = 2000 W. The total power consumption of the shirt ironer 100 can be a power P2 in the second operating state BZ2, for which the following applies: 100 W £ P2 <5000 W, advantageously 1000 \ N <P2 3000 W, further advantageously 1500 W P1 ^ 1800 W, further advantageously essentially P2 = 1600 W. The total (maximum) power consumption PG of the shirt ironer 100 is essentially due to the power consumption of the fan 144 in accordance with a cold air functionality, the first heating device 142 and the fan 144 in accordance with a warm air functionality (i.e. with activated second heating device 152 ) certainly. Because these components are not activated at the same time in any operating state, the overall power consumption PG of the shirt ironer can advantageously be reduced. It therefore corresponds to performance P1.

The operating and display part 114 can enable a user to select an individual operating state BZ1, BZ2 or a combination of the operating states BZ3. Accordingly, the method for smoothing the shirt, depending on the user choice, can only comprise individual aspects described above. The operating and display part 114 can also serve to specify a preset level of moisture in the shirt, for example because the shirt is still wet from the washing process. In response, the shirt ironer 100 can be set up to dispense with the first operating state BZ1 or to carry it out only partially (with a reduced length and / or intensity). The operating and display part 114 can also be used to display warnings for a faulty operating state, for example a shirt ironer 100 falling over or shirt ironer 100 overheating due to the fill level of the first reservoir 140 being too low. Furthermore, the operating and display part 114 can also serve this purpose to display various shirt ironer 100 operating parameters.

FIG. 3 shows a simplified schematic cross-sectional view A-A of part of the base 110 of the shirt ironer 100 according to the position indicated in FIG.

There is the annular gap 124 between the outer edge 122 of the cover 120 and the border 1 16 of the side wall 1 15 of the base 1 10. There is also the first reservoir 140 which is ready to receive a quantity of water. Access to the first reservoir 140 or filling is possible by means of the flap 126 which can be opened. The first reservoir 140 has at least one depression 146 in which the water can collect in the event of a low fill level. The first heating device 142 is located at the lower end of the depression 146. The first heating device 142 is arranged in a concealed manner, as seen from the first reservoir 140. The first heating device 142 can be used to heat at least part of the water located in the first reservoir 140. As a result, the water vapor thus generated can escape from the first reservoir through the annular gap 124.

The depression ensures that even in the event of a low fill level of the first reservoir 140, at least some of the water collects in the immediate vicinity of the first heating device 142. There is also an overheating sensor 148, which is set up to indicate that the corresponding part of the base 110 is overheating, for example because all the water has evaporated through heating. The overheating sensor 148 is preferably arranged in the region of the lowest level 147 of the depression 146, but can also be arranged in another region in the region of the first reservoir 140, depending on the configuration. The shirt ironer 100 can be set up in such a way that the heating device is switched off automatically if the overheating sensor 148 outputs a corresponding signal. The first reservoir can also comprise a plurality of corresponding depressions and / or heating devices and / or overheating sensors. The volume V of the first reservoir 140 can be sufficient to provide at least one shirt with sufficient water vapor (corresponding to the first operating state BZ1), so that a significant improvement in the ironing result can be achieved (after the second operating state BZ2 has been carried out). The volume V is advantageously sufficient so that a corresponding vapor deposition can be carried out completely several times, in particular twice. It can thus be avoided that the first reservoir has to be filled up after each individual vapor deposition. The following can apply to the volume V: 100 ml £ V <5000 ml, advantageously 300 ml <V <2000 ml, further advantageously 500 ml s V <1000 ml, further advantageously V can be essentially 750 ml. With a complete vaporization cycle corresponding to the first operating state, a water volume VB of essentially 350 ml can be consumed.

The duration of the first operating state BZ1 in which the shirt pulled over the doll 200 is acted upon by water vapor conveyed by the blower 144 is variable. The first operating state BZ1 can therefore be active for different time intervals. In a first embodiment of the first operating state BZ1, the duration can be a time interval t1. In a further embodiment of the first operating state BZ1, the duration can be a time interval t1 *, where t1 t1 *. The duration of the first operating state BZ1, in which the shirt pulled over the doll 200 is acted upon by water vapor conveyed by the blower 144, depends in particular on the amount of water in the first reservoir 140.

The shirt ironer 100 includes a fill level detection functionality that can detect the fill level of the first reservoir 140. In addition, the shirt ironer 100 includes a control functionality which determines the required length of the time interval of the first operating state BZ1 for the shirt to be supplied with sufficient water vapor based on the determined fill level.

A higher fill level of the first reservoir 140 requires that the first time interval t1 for the shirt to be exposed to the conveyed water vapor is longer than with a lower fill level of the first reservoir 140. In other words, a time interval of essentially t1 = 7 min is sufficient to moisten the shirt when the fill level of the first reservoir 140 is essentially 350 ml. However, if the fill level is essentially 700 ml to 750 ml, a time interval t1 ^{* is} necessary to apply sufficient steam to the shirt, for which the following applies: t1 ^* > t1. In this way, the shirt ironer 100 is advantageously set up to implement different durations of the first operating state BZ1. In particular, an optimal result of the moistening of the shirt is thus ensured even with a variable filling level of the first reservoir 140.

The shirt ironer 100 can alternatively also be set up in such a way that a user presets the fill level using the control and display panel 114 and that the shirt ironer 100 determines the duration of the first operating state BZ1, in particular the steaming of the shirt with water vapor, depending on User prefix determined. Thus, the shirt ironer 100 can be set up, even without fill level detection functionality, to select the steaming period in spite of the variable fill level of the first reservoir 140 in such a way that the shirt pulled over the doll 200 is sufficiently steamed. The preselection of the user can also include the option to run several vaporization processes in succession in accordance with the first operating state BZ1. Accordingly, this can influence the choice of the duration of the first operating state BZ1 by the shirt ironer 100.
