Description

  • The present invention relates to a steam iron according to the preamble of patent claim 1.
  • It is known to provide steam irons with a wide variety of humidifying functions. These steam irons have in addition to the usual spray function, by which no steam, but a water mist is distributable to the ironing, also provided steam outlet openings in the soleplate. From the EP 0 908 551 A1 It is also known, in addition to the steam outlet openings form steam channels in the soleplate, which forward the steam in the area surrounding the soleplate and are in pressure-equalizing with the steam outlet openings in communication. The steam for these two steam outlet paths is generated in a common steam generating chamber, which is continuously supplied with water by means of a drip valve. It is thus set in this prior art by a Dampfmengeneinstellrad durchlassbare through the drip valve amount of water, which thus equally the amount of steam for the formed in the soleplate steam outlet openings and in the opening end of the steam channels of the soleplate is forwarded. The steam that hits outside of the soleplate on the possibly not yet ironed and thus heated ironing, has a higher wrinkle smoothing effect, since the temperature difference between steam and ironing is greater than normally, when the ironed by the soleplate is already heated and in addition Steam outlet openings in the soleplate with steam is applied.
  • From the DE-41 33 295 A1 , the disclosure of which forms the preamble of the subject of claim 1, a steam iron with two mutually separate steam generating chambers is known. In this case, a first steam generating chamber is connected to a drip valve for continuous water supply. The second steam generating chamber communicates with a water pump, so that water can be injected into the second evaporating chamber upon manual operation. The steam generated via the second evaporation chamber is passed via a steam guide channel to a jet steam outlet opening. This jet steam outlet is located above the ironing tip and allows in this way a preconditioning of the material to be ironed or a Dampfbefeuchten in certain areas, such as the breast pocket of a shirt.
  • From the WO-9606970 is a to DE-41 33 295 A1 However, it is stated that the steam generating chamber for the jet function is formed in a labyrinth-like manner in order to provide a narrowed, elongated space for steam generation, via which the steam outlet speed in conjunction with the injection of the water via a pump into this second steam generating chamber can be significantly increased is so that the jet function provides a burst of steam.
  • Trial tests have shown that it is desirable, especially in the area of the iron tip even more steam than shown in the above examples - with simultaneous ease of use - provide.
  • From the WO 2005/059232 A1 Steam irons are known with a motor-driven electric pump for water and steam, which have a jet steam outlet opening above the ironing iron and outlet openings in the soleplate, which are each connected via steam ducts either to a common or each separate steam generating chambers. In the case of separate chambers, the also separate channels to the outlet openings are provided with check valves, in the case of a common chamber with three-way valves, in both cases the valves switch the steam delivery of the combination pump-steam generating chamber. Such irons do not have to take any special precautions to steam because of the pressure generated by the pump. However, the disadvantage of this prior art is above all the additional weight of the electric pump and the associated higher initial costs, so that this type of iron could not prevail on the market.
  • From the US 3,130,507 A Finally, a steam iron is known, which has on the one hand connected to an internal water tank first steam generating chamber for feeding steam outlet in the soleplate and on the other connected to an external pressure water line second steam generating chamber for feeding a single small spray steam outlet opening, both above the ironing iron tip as well as in the soleplate can be formed. Both the two chambers and the respective steam channels are separated and are controlled separately via respective pressure or screw valves.
  • It is therefore an object of the present invention to provide a steam iron of the above type, the steam application possibilities are further optimized without affecting the handling of the iron thereby.
  • This object is achieved by a steam iron with the features of claim 1. Thus, for the jet steam outlet opening and the steam outlet openings in the soleplate, the same steam guide area with the same steam generating chamber is used to a large extent. Thus, the function is extended to the extent that by injected water into the second steam generating chamber, a steam pulse is generated, which can serve both for preconditioning of the ironing with steam above the ironing tip and for steam injection below the soleplate. Handling is also simplified insofar as the same actuating button can be used for both functions. In addition, the use of a common steam generating chamber for reasons of space economy advantageous.
  • In a further advantageous embodiment, this function is provided parallel to the normal steaming function via steam outlet openings in the soleplate, since this is a separate steam generating chamber is provided.
  • In a further advantageous embodiment of the first steam guide region via a drip valve is continuously supplied with water for a correspondingly continuous generation of steam. Thus, depending on the opening setting of the drip valve, water is continuously dripped into the first steam generating chamber via the first steam guide region, which water is continuously converted into steam and carried out via the steam outlet openings in the soleplate.
  • In an advantageous embodiment, a first steam actuation button is provided, via the actuation of which an increased amount of water can be fed to the first steam generating chamber. In this case, the first actuating button is mechanically coupled to the drip valve, such that an axial displacement of the drip valve leads to an increased water supply to the first steam generating chamber. Thus, the function key for the first steam guide region is designed to be two-functional: On the one hand, by pressing the first actuation key, an abruptly increased amount of water can be fed via the drip valve into the first steam generating chamber, so that over all the steam outlet openings of the soleplate a leaps and bounds increased amount of steam emerges.
  • In addition to this first actuating button and the usual spray button for water mist, a second actuating button is provided in an advantageous development, which is coupled to a water pump, wherein the water pump with the second Steam generating chamber is in communication, so that by an operation of the second steam control button water via the water pump to the second steam generating chamber is pumpable. Thus, an abruptly increased amount of water in the second steam generating chamber can be injected via the second steam actuation button, so that in a short time sufficient water is available to produce a steam burst with increased steam velocity in the second and third steam guide region.
  • In an advantageous embodiment, the first and second steam generating chamber is separated from each other by partitions, so that over narrowed labyrinth passages in the second steam generating chamber, an increased steam propagation speed can be generated. This also provides an important factor for the generation of a steam pulse. Due to the injection of water and the labyrinthine design of the second steam generating chamber, the steam pressure on actuation of the second steam control button is significantly higher than after the operation of the first steam control button.
  • In an advantageous development, the first steam guide channels are connected to all steam outlet openings of the soleplate. This has the consequence that the steam outlet openings in the ironing tip area are also supplied with steam when the second steam control button remains unactuated.
  • In a further advantageous embodiment, the second steam guide region has a specific steam supply opening, which is immediately adjacent to a plurality of steam outlet openings in the front soleplate tip region. Thus, steam can be supplied to the steam outlet openings in the ironing tip region via the second steam control button, wherein the steam outlet from the remaining steam outlet openings is significantly reduced due to the much longer path to be covered. Advantageously, the steam blast thus takes place precisely in a region in which an increased demand for steam is usually provided for regions of the ironing material which are difficult to be ironed over.
  • Due to the immediately adjacent arrangement of the specific steam supply opening to the steam outlet openings in the soleplate in the region of the iron tip is at least 60%, in particular more than 75% of the total steam, which rests against the steam outlet openings of the sole plate, feasible to steam outlet openings arranged in the region of the soleplate is. Thus escapes by pressing the second steam control button of the most part in the front quarter, especially in Front fifth of the soleplate, based on the total length of the soleplate from the temple tip to the rear end of the soleplate.
  • In an advantageous development, the second steam guide channel has a vapor intermediate collecting region, which is provided on the one hand with the specific steam outlet opening and on the other hand with the branch to the third steam guide channel. Since the vapor pressure in the second and third steam guide regions is not so high despite the steam-escape, it is important that the steam be led and accumulated to the location in the steam channel body which is in close proximity to the specific steam feed and branch and on the other hand Steam outlet openings in the temple tip area and the jet steam outlet opening is located. Advantageously, the specific steam supply opening and the branch are arranged directly adjacent, so that the steam is divided into not too different proportions at the branch to the various steam outlet openings.
  • In an advantageous embodiment of the third steam guide channel is provided with a steam pressure controllable valve, wherein the valve is designed such that it releases the steam to the jet steam outlet opening vapor pressure dependent. The valve is designed such that the threshold pressure for opening the valve is higher than the vapor pressure which can be generated via the first steam generating chamber. This ensures that no vapor escapes from the jet steam outlet opening in the continuous steaming operation.
  • Advantageously, the valve is designed as a plastic diaphragm valve. Accordingly, no coil spring with ball, but a vapor pressure-dependent elastically deformable plastic cloth is provided, which is deformed by the vapor pressure such that the steam path is releasable.
  • In a further advantageous embodiment, a steam chamber body is provided, in which the first and second Dampfführungsbereich are provided, wherein the steam chamber body is formed as Aluminiumdruckgußteil and wherein in the soleplate tip portion a recess is provided in the steam chamber body in which a boundary wall formed parallel to the soleplate and to limit the intermediate steam collecting area is. This boundary wall is advantageously only a metal plate which is inserted into the recess in the aluminum die-cast from below, so that in the casting - apart from the inlet and outlet openings - in a cavity steam is collectable.
  • Other features, applications and advantages of the invention will become apparent from the following description of embodiments of the invention, which are illustrated in the figures of the drawing.
  • The figures show:
  • FIG. 1, 3, 5 and 7:
    each a spatial representation of a steam iron according to the invention in different conditions of use;
    FIG. 2, 4, 6 and 8:
    depending on a plan view of the control panel of the steam iron after FIG. 1 ;
    FIG. 9:
    a partly schematic longitudinal section through the steam iron after FIG. 1 ;
    FIG. 10:
    a longitudinal section through a schematic view of the lower assembly of the steam iron after FIG. 1 in a state of use, in which steam exits only by the actuation of the second steam control button;
    FIG. 11:
    a representation like in FIG. 10 however, in which the use state is shown in which only steam is generated from the first steam guide region;
    FIG. 12:
    a plan view of a steam chamber body of a steam iron after FIG. 1 and
    FIG. 13:
    a spatial exploded view of the lower assembly of the steam iron after FIG. 1 ,
  • The FIGS. 1, 3, 5 and 7 show the steam iron in a different state of use with respect to the activation of a steam ejection or a water spray. The FIGS. 2, 4, 6 and 8 show a section of a plan view of the steam iron in the region of the handle, in particular the control panel 14 and its for the respective steam or spray function to be operated device.
  • FIG. 1 shows the steam iron in the so-called "normal steam function" in which steam exits from all the steam outlet openings of the steam iron sole plate (in a variant, not all steam outlet openings of the steam iron sole plate can be supplied with steam in a normal steam function). In the figure, therefore, evenly below the soleplate, steam clouds 1 of the same size are shown symbolically relative to each other. This normal steam is produced by dripping water from a water tank in the steam iron via a drip valve - depending on its open position - in a first steam generating chamber. All steam guide portions are arranged in a cast aluminum steam chamber body, said cast body is electrically heated. The steam generated in the first steam generating chamber is passed via first steam guide channels above the soleplate to the steam outlet openings in the soleplate. There, the steam then exits. This steam is supplied continuously so there is no steam button to press it.
  • To regulate the amount of steam that drips into the first steam generating chamber via the drip valve, the steam quantity regulator 2 is in FIG. 2 in the specified regulatory area 3 rotatable between a closed position and a maximum water supply point.
  • FIG. 3 shows the steam iron in a use state in which compared to the amount of steam 1 in FIG. 1 an increased amount of steam 4 emerges from all the steam outlet openings of the soleplate. To generate this about the sole plate surface uniformly increased amount of steam is the first steam control button 5 according to the indicated arrow 6 in FIG. 4 and in FIG. 3 about to depress vertically. By this operation, the drip valve is transferred to an operating state in which an increased water supply is introduced into the first steam generating chamber, so that as a result a larger amount of steam is available.
  • FIG. 5 shows the steam iron in a state of use without the continuous steam FIG. 1 or the increased amount of steam after FIG. 3 in which a shot of steam takes place in two different directions. Via a second steam guide region in the steam chamber body, the steam is carried out from all the steam outlet openings of the steam iron, 80% of this steam is ejected in the foremost tip region in a portion of about 1/5 relative to the total axial length of the soleplate and starting from the ironing tip. The steam jet, which takes place in the second steam direction, is led via a third steam guide region to a jet steam outlet opening, which is arranged just above (ie approximately 0.5 to 1 or at most 2 cm above the soleplate or the ironing iron tip). To actuate this combination steam function, in which two different steam functions are combined with each other, the second steam control button 9 according to the arrow 10 in the FIG. 5 and 6 depress. The second steam actuation button 9 is in communication with a water pump, so that water is pumped from the water tank by the actuation of this button and injected into the second steam generating chamber.
  • The FIG. 7 finally shows the steam iron with activated water spray function. This is done by pressing the spray button 12 (see FIG. 8th ) in the direction of arrow 13, water is pumped from the water tank to the spray 60 so that a water jet 11 or cold water mist escapes in front of the ironing iron tip.
  • Of course, all of the above separately shown usage states may also be used simultaneously depending on the user's request.
  • FIG. 9 shows the steam iron in a side view, the lower assembly is shown schematically in longitudinal section. At the front region of the iron handle 15, the actuating portion 14 is arranged, in which the actuators and keys of the FIG. 2, 4, 6, and 8 are arranged. Inside the housing of the steam iron a water tank 16 is arranged. Below the water tank, a steam chamber body 17 is provided which is formed as Aluminiumdruckgußteil and in which the various steam guide portions are added. In the steam chamber body 17, an electric heater is cast with, which supplies the steam chamber body and the sole plate 18, which adjoins below the steam chamber body, with heat. In the soleplate 18 a plurality of steam outlet openings 19 are provided distributed over the entire longitudinal extent. As in particular in FIG. 13 shown, the steam outlet openings 19 are distributed over the entire sole plate surface, which is adjacent to the soleplate tip 21 over a longitudinal extension of about 1/5 of the soleplate viewed from the longitudinal section with a group of steam outlet openings 20, which supplies the soleplate tip area with a lot of steam. Of the steam outlet openings 20 in the soleplate tip region at least 10, preferably more than 15 steam outlet openings are provided.
  • The water in the tank 16 is after FIG. 9 discharged via two outlets 22 and 23. At the outlet 22, the water is sucked in by the preferably manual pump 24. Via the pumping channel 25, the water is injected into the second steam generating chamber 26. To actuate the pump, press the second steam control button 9 by the user. The second steam generating chamber is a constituent part of the second and third steam conveying regions 27 and 28. The steam generated in the second steam generating chamber 26 enters the intermediate vapor collecting region 29. In the intermediate vapor collecting region 29, a branch 30 is provided in which the steam is introduced into the second and third steam ducts 35 and 33 divides. The vapor intermediate collecting area 29 is delimited downward by a boundary wall 36. The wall 36, according to FIG. 13 is formed as a metal plate is inserted into a cavity of the steam chamber body 17 from below. The boundary wall 36 has a specific steam supply opening 37, via which the steam is conducted further in the second steam guide channel 35 to all steam outlet openings 19, but especially to the steam outlet openings 20 in the tip region. Characterized in that the specific steam supply opening 37 is disposed immediately adjacent to the steam outlet openings 20 in the ironing iron tip area, 70 to 80% of the total steam exiting the soleplate 18 in this steaming function exits through the steam outlet openings 20 in the soleplate tip region.
  • In the schematic sectional view to FIG. 9 Also, a shoulder is formed in the steam chamber body, which delimits the second steam guide portion slightly to the first steam guide portion 40, but both are not completely separated from each other, since a passage 39 - albeit designed as a bottleneck - is provided. The passage 39 ensures that the steam in the normal, continuous steam operation, in which steam exits the steam outlet openings 19 via the first steam guide region, also passes steam to the steam outlet openings 20 in the soleplate tip region.
  • In the upper direction, the steam generated in the second steam generating chamber 26 and passed to the intermediate vapor collecting area 29 may branch not only down to the second steam duct, but also up to the third steam duct. However, in order for the steam to reach the third steam delivery channel 33, the applied vapor pressure must be sufficient to open the valve 34 due to the vapor pressure. The valve 34 is a part of the wall intermediate the steam intermediate collecting area. The valve 34 is - as in FIG. 13 shown - formed as an elastomeric plastic part which is glued into the opening 41 of the steam chamber body 17. In the valve 34, a membrane is included, which has a longitudinal or cross recess. The thickness of the membrane is so dimensioned that a vapor generated by the first steam guide region can not open the membrane with its corresponding pressure. After passing the steam in the third steam duct 33, the steam exits in the jet steam outlet 32. The jet steam outlet 32 and the third steam duct 33 are as in FIG FIG. 13 illustrated - formed in a plastic tip insert part 42 which is plugged into the lower assembly of the steam iron in the region of the steam chamber body front of the temple tip region 21. This part 42 is made of heat-resistant plastic.
  • A drip valve, not shown in the figures, establishes the second connection between the tank and the steam chamber body 18. For this purpose, an opening 23 in the vapor chamber lid 43 is formed, in which the drip valve - surrounded by a drop valve seal 44 (see FIG. 13 ) - is used. In an opening position of the drip valve, water of the tank 16 drips into the first steam guide area 45. The first steam guide region 45 is formed by a first steam generating chamber 46, in which the dripping water evaporates, and a first steam guide channel 40, which forwards this generated steam to the steam outlet openings 19 and 20 of the soleplate.
  • The arrows 47 in FIG. 9 and FIG. 10 illustrate the water and steam path for generating the combined steam function, in which below the soleplate and above the soleplate steam in the ironing tip region 21 is provided in two different steaming directions.
  • FIG. 10 and FIG. 11 are schematic sectional views of the lower assembly of the steam iron. FIG. 10 shows by the arrows 47 showing the steam path, the state of use, in which FIG. 5 and FIG. 6 the second steam control button 9 has been pressed. FIG. 11 shows the usage state FIG. 1 to FIG. 4 in which the steam passes via the first steam guide region 45 to the steam outlet openings 19 and 20 in the soleplate, but not to the jet steam outlet opening 32. The steam route is in FIG. 11 illustrated by the steam arrows 48 according to this state of use. The arrow 49 in FIG. 11 should illustrate the water supply via the drip valve schematically. As in FIG. 11 Also, as shown by steam arrow 48 at location 50, steam will enter the intermediate vapor collection area 29, but will not overcome membrane valve 34 due to the lower vapor pressure.
  • FIG. 12 shows the steam chamber body 17 without patch steam chamber lid 43 in plan view. In the middle, the larger, first steam generating chamber 46 is arranged, which causes no increased steam velocity in the steam generation due to their training. The second steam generating chamber 26, which is completely separate from the first steam generating chamber 46, has labyrinth passages through which the steam - as shown in FIG WO-9606970 known - initially following the directional arrows 52 against the direction of the ironing tip wanders and then passes according to the drawn steam arrows 53 in a direction back to the bow tip and thus to the passage opening 51. The passage opening 51 is in communication with the vapor intermediate collecting area 29, so that the steam can then be forwarded there. The labyrinth passages of the second steam generating chamber lead to an increased steam propagation velocity, so that in combination with the water to be injected a steam pulse is generated, which propagates with increased pressure and which in any case is far enough to enable the diaphragm valve 34 in the open position.
  • FIG. 13 shows an exploded view of the lower assembly of the steam iron. The boundary wall 36 is clamped in the front tip portion in a cavity, and then the steam chamber body 17 can be secured to the sole plate 18. In the steam chamber body 17, the valve 34 is glued into the opening 41 and the plastic tip is used for the third steam guide region in the temple tip region 21. The steam chamber lid 43 closes the steam generating chambers upwards. In the steam chamber lid 43 is an opening for the seal 44 for the drip valve and a second opening 54 for the seal 55, to which the channel 25 connects, is provided. On this assembly, a metallic heat protector 56 is screwed with the screws 57, which protects the upper assemblies from the heat dissipation of the lower assembly.
