Definitions

  • the present invention relates to a gasket for a steam iron and a steam iron.
  • Irons are known from the prior art, which have one or more evaporation chambers in addition to a water tank to generate steam or steam surges there. In this case, water is brought to a preheated surface, wherein the water evaporates and the steam is then discharged. This can be done for example by openings in the sole of the iron.
  • Steam irons have several channels or lines through which water is directed to the respective points or chambers. For example, one line may connect a water tank to a steam chamber, another line may connect the water tank to an auxiliary steam chamber, and another line may connect the water tank to, for example, a descaling device that may be formed in cooperation with a steam chamber.
  • a steam iron is e.g. known from EP 0 866 162 A2.
  • conventional steam irons Due to the existing plurality of conduits or channels extending, for example, from the water tank to the various valves, steam generating chambers, purging devices, descaling devices, etc., conventional steam irons also have a plurality of seals which seal the individual components as watertight as possible connect. In order to ensure a watertight connection, these seals must be carefully used and checked, as leaks can lead to errors in the operation of the iron up to failures.
  • the invention has for its object to provide an improved concept for sealing the components of a steam iron.
  • Embodiments may therefore be based on the insight that the fewer seals that are present in a steam iron, the less time it takes to assemble and control. Embodiments are therefore based on the knowledge that the assembly can be facilitated by the integral formation of a seal which is provided for sealing a plurality of channels or lines.
  • Embodiments provide a one-piece seal for a steam iron that is configured to provide a watertight transition from a water tank to a steam chamber and to provide a watertight transition from the water tank to an auxiliary steam chamber.
  • the one-piece design of the seal can have advantages during assembly, since several waterproof connections can be achieved with the mounting of a single seal. By mounting the one-piece seal on the one hand a watertight connection between the water tank and the steam chamber and on the other hand can be created between the water tank and the additional steam chamber, with only a common assembly step is performed.
  • the seal may be further configured to provide a watertight transition from the water tank to a descaling device.
  • the integrally formed seal unites watertight connections for three components, namely, starting from the water tank to the steam chamber, the auxiliary steam chamber and the descaling device.
  • the descaling device is used for descaling the steam chamber, or the additional steam chamber, or those components of the iron, the lime deposits are accessible, such as the soleplate.
  • the decalcification can use the steam chamber and provide that after heating the components in question a relatively large amount of water for rapid cooling of the components is supplied to them, so that any lime deposits flake off by the rapid change in temperature and can be flushed over the soleplate.
  • the descaling device can correspond to an inflow to the steam chamber, via which a correspondingly larger amount of water can be conveyed into the steam chamber. In such embodiments, three functions can now be combined in a one-piece seal.
  • the seal may comprise silicone or plastic.
  • the seal may be formed of silicone or plastic.
  • the use of silicone or plastic may have the advantage that these substances or materials are less accessible to limescale deposits than, for example, metal surfaces in the steam chambers.
  • the seal may further include a valve for interrupting the transfer of water from the water tank into the steam chamber.
  • a further function namely that of a valve, be integrated.
  • the valve may for example be located between the water tank and the steam chamber, for example in the form of an anti-drip device (also drip-stop device or system).
  • an anti-drip device has the advantage that a dripping of water into the steam chamber is prevented or at least reduced.
  • the seal may further comprise a connection piece for connection to the water tank, the steam chamber, the additional steam chamber or the descaling device.
  • the seal is now no longer just a mere sealing function, but also a connection function.
  • the connection piece can interact with corresponding connection counterparts on the components in such a way that watertight cross-overs are formed.
  • the connecting piece may for example be formed cylindrically, so that it can be slipped over a corresponding flange. If the connecting piece is cylindrically shaped, then its position can be determined simply and precisely during assembly, precisely just by slipping over onto counterpart connecting pieces or flanges provided for this purpose. The assembly process can then be relatively easy and fast.
  • the seal may also have a plurality of connecting pieces, for example one for water tank, steam chamber, additional steam chamber, etc.
  • the seal can also provide that there are several connections to the water tank, wherein a connection piece is provided on the seal for each of these connections ,
  • the seal may then be formed by at least two parallel, interconnected pieces of tubing, which are water tank side slipped onto different ports, with one piece of tubing then leads to the steam chamber and the other to the additional steam chamber.
  • the at least two connecting pieces may also have different diameters. Different diameters have the advantage that they allow different flow rates at the same pressure in the water tank and therefore can be adapted to the needs of the respective component.
  • the function of the descaling device is determined by applying a larger amount of cold water in a short time to the lime-affected components, such as the steam chamber, so that the lime will chip off there before it is flushed out.
  • a larger amount in a short time Water is needed to achieve a shock-like cooling, as is the case, for example, in a steam blast.
  • Steam bursts are generated in the additional steam chamber and last only a short time, for example 0.2-2 s. In this time, about 1-6g of water are evaporated, the diameter of the relevant connecting piece is then designed so that this amount can be provided.
  • the seal can provide a first connection piece, via which the water tank can be connected to the steam chamber.
  • the seal may provide a second connection piece, via which the water tank can be connected to the additional steam chamber.
  • the seal can provide a third connection piece, via which the water tank can be connected to a decalcification device.
  • embodiments may provide a silicone gasket that directs water from a steam chamber of a steam iron into a steam chamber and directs water from the steam chamber into an auxiliary steam chamber of the iron.
  • the seal may for example comprise three channels or lines and thus additionally incorporate a descaling device.
  • the seal is integrally formed and may have three passages or channels, which supply water to the generation of steam, additional steam and for descaling.
  • the seal may include an opening and closing system (valve), through which the water supply to the steam chamber can be influenced, and which can cooperate with a bimetallic component.
  • the bimetallic component may be arranged on the soleplate of the steam iron and react accordingly with the temperature of the soleplate, for example for the realization of an anti-drip system.
  • Embodiments also provide a steam iron with one of the seals described above.
  • the drip-stop device of the gasket may be provided with a bimetallic member of the steam iron cooperate, so that over a temperature of the soleplate, the water supply to the steam chamber can be influenced.

  • Fig. 3 shows an embodiment of a steam iron in a further sectional view.
  • like reference characters designate like or similar components.
  • Fig. 1 shows an embodiment of the seal 10 for a steam iron 100, of which a detail in Fig. 2 is shown.
  • 2 shows an embodiment of a seal 10, as described with reference to FIG. 1, in the installed state in a steam iron 100 in a sectional view from the underside of the steam iron 100 from.
  • Fig. 3 shows an embodiment of the gasket 10 in a side sectional view of the steam iron 100.
  • Fig. 3 illustrates the basic structure of an embodiment of a steam iron 100.
  • the steam iron 100 shows in the middle the gasket 10 and above the water tank 20.
  • the steam iron 100 is closed at the bottom by the sole plate 40.
  • FIG. 1 illustrates an embodiment of the one-piece gasket 10 which is adapted to provide a watertight transition 12 from a water tank 20 (see Figures 2, 3) to the steam chamber 50 and a watertight cross-over 14 from the water tank 20 to provide an additional steam chamber 60.
  • the exemplary embodiment of FIG. 1 illustrates an embodiment of the one-piece gasket 10 which is adapted to provide a watertight transition 12 from a water tank 20 (see Figures 2, 3) to the steam chamber 50 and a watertight cross-over 14 from the water tank 20 to provide an additional steam chamber 60.
  • FIG. 1 also shows a watertight transition 16 from the water tank 20 to a descaling device 70, which is formed by an enlarged inflow to the steam chamber 50 in relation to the regular inflow to the steam chamber 50.
  • the embodiment of the one-piece seal 10 shown in FIG. 1 thus provides three watertight transfer lines 12, 14, and 16.
  • the seal 10 may for example comprise silicone or plastic, in the embodiment of FIG. 1, this is formed entirely of silicone.
  • the unitary gasket 10 further includes a valve 30 for interrupting the passage 12 of water from the water tank 20 into the steam chamber 50.
  • This valve 30 may thus be used to form a drip-stop device 30.
  • the valve 30 can cooperate with a bimetal component 32 such that the valve 30 is actuated via the bimetallic component 32.
  • the bimetallic component 32 is in thermal coupling with the soleplate 40, which is not shown in FIG. 2 for the sake of clarity, but whose position can be seen in FIG.
  • the bimetallic component 32 which is here dish-shaped (see Fig. 2), expands depending on the temperature of the sole plate 40, or contracts, and thus actuates the valve 30.
  • valve 30 is closed, so that no more water enters the steam chamber 50 (see Fig. 3), and so the sole plate 40 is not further cooled by the water, or no further steam is generated and no unvaporized water from the soleplate 40 exits or expires.
