Definitions

  • the invention relates to an electrically operated iron, in particular a steam iron, with a handle and a housing for accommodating an electric heating device and with an iron soleplate.
  • Electric irons especially steam irons
  • the electrical heater arranged inside the housing of the iron is generally designed as an electrical resistance heater, ie the electrical current flows through a resistance wire and heats it up.
  • Such electrical resistance heaters are available in different embodiments. However, they all have significant disadvantages. First of all, a relatively large amount of effort is required in their manufacture and also in assembly. This applies in particular if the resistance wire is attached to supports made of insulating material. It is particularly disadvantageous that the electrical resistance line requires a very long start-up time. This means that a relatively long time passes until the maximum heat output is reached after the power is switched on. On the other hand, once the resistance wires have been heated up, they give off a considerable amount of heat after the electrical current has been switched off and are lost unused. The efficiency of the electrical resistance heaters can therefore be described as poor.
  • iron soleplates Numerous embodiments are also known with regard to the design and shape of the iron soleplate. So there are iron soles that are made of a single material. In addition to aluminum iron soles, there are also steel soles. Aluminum iron soles have a relatively low weight and good thermal conductivity. In contrast, the abrasion resistance is low. In contrast, iron soles made of steel have a relatively high weight and a relatively poor thermal conductivity, while the abrasion resistance is high.
  • the invention has for its object to further improve electrically operated irons, in particular steam irons, of the type characterized in more detail at the outset.
  • the improvements should relate both to the electric heating device to be used for the iron and to the design of the soleplate. Both parts of the iron should be both easy to manufacture and easy to assemble in comparison with the known, while at the same time they should have performance characteristics that are superior to those of the electric heaters and soleplates used to date.
  • the invention proposes that at least one halogen lamp is used as the heating device, which is surrounded in regions by a reflector, and that the soleplate of the iron is infrared radiate permeable and heat-storing plate, preferably a glass ceramic plate.
  • the inventive design of an electrically operated iron has considerable advantages over the known.
  • the halogen lamp to be used as a heating device has the advantage over the previously used electrical resistance heating that it requires practically no heating time. After switching on the electrical current, the full thermal energy is released almost immediately. Conversely, the heat emission stops immediately after switching off the electrical current. It is advisable to use halogen lamps as heating devices in which there is an increased infrared yield.
  • the halogen lamp in the iron according to the invention is to be used as an infrared dryer, that is to say as a dryer in which the energy required for the evaporation or evaporation of liquids is transmitted to the material to be dried by infrared radiation. Since the infrared radiation is strongly absorbed by liquids, the infrared rays emanating from the halogen lamp can be used to selectively evaporate liquids or the like in the items to be ironed. bring about. Absorption of infrared rays by textile materials or the like. is much less.
  • halogen lamps can be accommodated in the housing of the iron. It is in your hands to change the number of halogen lamps to be accommodated in the housing. In the simplest case, a single halogen lamp is sufficient. In special cases, however, it is also possible to use more than one halogen lamp. There is the further possibility that the halogen lamp is switched on individually or in groups. For example, you can have all the halogen lamps in the iron housing work, or only a few or a single halogen lamp. In this way, adaptation to the ironing work to be carried out is possible.
  • the soleplate of the invention consists of a single material, which is designed so that it once passes the infrared rays that come from the halogen lamp, but also acts as a heat accumulator.
  • glass ceramic in particular, is suitable for the production of an iron soleplate with such properties plates are suitable.
  • the infrared rays penetrate an iron sole made of glass ceramic almost unhindered and reach the material to be treated with the iron, where they ensure evaporation of the liquid contained in the iron.
  • the glass ceramic plate used as the soleplate of the iron also acts as a heat store, which transfers its heat to the items being ironed.
  • the glass ceramic plate has a lower coefficient of friction and that its surface can be kept very flat, which makes ironing extremely easy.
  • there is a high mechanical strength of the glass ceramic plate so that there is no need to fear warping, as can occur, for example, with two-layer iron soles.
  • the soleplate which is designed according to the invention as a glass ceramic plate, is expediently detachably connected to the housing of the iron. Connection elements or connection types known in the art can be used for this.
  • the detachable connection of the glass ceramic plate to the housing makes it possible to make the inner parts of the iron accessible, if necessary, in order to carry out work which, for example, consists in cleaning operations or replacing defective parts with new ones.
  • the housing has at least one halogen lamp socket.
  • This can be connected with known fastening elements to parts of the housing wall.
  • two halogen lamp sockets to the housing, which are located on diametrically opposite sides and which have coupling elements and electrical contacts in a known manner, which can interact with the corresponding parts of the halogen lamp.
  • the reflector has an essentially semicircular cross section. It is provided that the center of curvature of the reflector lies in the base plane of the glass ceramic plate. The aim of this is to ensure that the infrared rays emitted by the halogen lamp are reflected back in the reflector in such a way that they strike the glass ceramic plate approximately perpendicularly.
  • the halogen lamp is approximately at the focal point of the reflector.
  • the reflector keeps the heat radiation away from the housing, so that it does not experience any appreciable heating when the iron is used. Overall, the iron according to the invention can be kept very low in weight.
  • the energy emitted by the halogen lamp can also be used to convert water into steam. It is possible to arrange an evaporator chamber for water in the interior of the housing of the steam iron delimited by the reflector. Drops of water can get into this from a water container, for example, and be vaporized there. The steam generated in the evaporator chamber can then enter the supply lines via the evaporator chamber and from there to steam nozzles, which protrude with their outlet openings into openings which are distributed in the glass ceramic plate in this. From there, the steam is then passed onto the material to be ironed in a manner known per se. It is of course possible to design the number of openings in the soleplate differently. It is expedient to make the individual openings in the glass ceramic plate the same as one another and to provide them in a regular arrangement. This simplifies production and has a beneficial effect on the steam distribution.
  • the iron or the steam iron can have a configuration and shape known per se. It should also be pointed out that only those parts of an iron are shown in the figures of the drawing which are important for understanding the invention. For example, the electrical contacts and the feeder cables are omitted for the sake of simplicity. This also applies to control and regulating devices. All missing parts can also have a structure known per se and can be arranged in a manner known per se on or in the housing of the iron.
  • the steam iron on which the exemplary embodiment is based is generally designated 10. It has a handle 11 and a housing 12. Plastics can be used in the production of both the handle 11 and the housing 12. It is possible to combine handle 11 and housing 12 into a one-piece structural unit.
  • the soleplate of the iron is designed as a glass ceramic plate 13 in the selected exemplary embodiment.
  • a material known under the trademark "Ceran” can be used in the production of the glass ceramic plate.
  • other materials can also be used.
  • these must be transparent to infrared rays and, on the other hand, they must include the possibility of heat storage.
  • the glass ceramic plate 13 can be connected to the housing 12 of the steam iron 10 in a manner known per se.
  • a halogen lamp 22 is assigned to the steam iron 1o as the electrical heating device. In the selected exemplary embodiment, this is designed as a rectilinear hollow cylinder body. A commercially available halogen lamp can be used. However, it is advisable to ensure that it is a halogen lamp which has a high proportion of infrared radiation emitted during operation.
  • the halogen lamp 22 is carried in a known manner by a halogen lamp holder 23 which is arranged in the rear part of the housing 12 of the steam iron 10.
  • the halogen lamp holder 23 carries the electrical contacts in a known manner.
  • the halogen lamp 22 On the opposite other side of the housing, the halogen lamp 22 also has a halogen lamp holder 23. This is omitted in FIG. 1 for the sake of simplicity, especially since it has the same design and shape as that shown in FIG. 1.
  • the halogen lamp 22 is surrounded by a reflector 24.
  • This has - as best seen in FIG. 2 - a semicircular cross-sectional shape, but the front part 25 of the reflector 24 is adapted to the inclined outer surface of the housing 12 of the steam iron 10.
  • the arrangement of the halogen lamp 22 in the reflector 24 is such that it lies approximately at the focal point of the reflector 24 which is semicircular in cross section.
  • the center of curvature of the reflector 24, which is semicircular in cross section, lies in the base plane of the glass ceramic plate 13.
  • the reflector 24 shields the housing 12 from the action of the heat rays.
  • a steam tank belongs to the steam iron 10, which is not shown for the sake of simplicity. For example, it can be accommodated in the handle 11. But there is also the possibility to attach it to the back of the housing 12.
  • a supply line 2o extends from it to a two-way valve of generally known type, generally designated 18, which is equipped with an actuator 19. From the two-way valve 18 a main line 17 goes out. From this, water can, for example, reach a vaporizer chamber (not shown in FIG. 1) in drop form. This evaporator chamber suitably lies in the space which is surrounded by the reflector 24.
  • the feed lines 16 and the steam nozzles 15 are shown on an enlarged scale. In practice, both parts are dimensioned much smaller.
  • the glass ceramic plate 13 have more than two openings 14. Rather, a multiplicity of openings 14 are generally used, which are expediently configured identically to one another and arranged in a regular arrangement over the glass ceramic plate 13.
  • the housing 12 terminates in a tip in a known manner.
  • the housing 12 of the steam iron 10 is also assigned a further water tank 26, which is only shown schematically in FIG. 1.
  • a feed pipe 27 goes to an atomizer 28, which is provided with an outlet 29.
  • liquid can be transferred to the item to be ironed if required, as is known in principle.
  • the atomizer 28 and the two-way valve 18 can be operated independently by the user.
  • the embodiment shown is only an example implementation of the invention and it is not limited to this. Rather, many other designs and applications are possible. This applies in particular to the design and arrangement of the halogen lamps 22. While only a single halogen lamp 22 is shown in the selected exemplary embodiment, a plurality of halogen lamps can also be accommodated within the interior of the reflector 24, if required. These can be switched in a known manner so that the user has the option of actuating all halogen lamps at the same time or to switch on individual halogen lamps or groups. This gives him the option of regulating the heat energy to be released, depending on the work to be carried out on the ironing material.
  • Fig. 1 with 21 a recording for controllers in a known design is shown. These regulators can be used to adapt them to the items to be ironed in a known manner.
