Definitions

  • the present invention relates to a water dosing system for water heating equipment, mainly for steam irons.
  • the object of the invention is to obtain a system that allows efficient cleaning, with a high flow of water to adequately drag any lime deposit created in the steam chamber.
  • Steam irons include a water dosing system that allows water to pass from the water tank to the steam chamber at the base or soleplate of the iron. It ensures that the water is dosed in the right amount so that it all turns into steam.
  • the system usually includes a device for continuous regulation from zero to a maximum amount of steam.
  • the most common way to implement it is a needle valve, made of plastic or metal, which goes up or down and varies the valve pitch.
  • an anti-drip system which includes a temperature-sensitive valve.
  • the valve only accepts the passage of water when the temperature of the steam chamber is sufficient. It generally incorporates a bimetal connected to the valve that opens and closes it. This system avoids water drops due to too low temperature or when dosing is left open.
  • Another device that can be incorporated in the irons is a cleaning system for the steam chamber. It serves to clean and remove the lime deposits that accumulate in the steam chamber, through periodic operations by the user, and thus prolongs the life of the appliance.
  • Steps usually consist of heating the base or soleplate to the normal use temperature, and cutting the power. Water is passed through the steam chamber, with a high flow rate to break up the deposits by thermal shock and drag them out. Finally, the iron is reheated, without any more water passing through the soleplate, to vaporize any remaining water.
  • Patent EP1007777 shows a cleaning device that performs a bypass of the anti-drip system.
  • the water jet for cleaning is focused on the same place wherein dosing is carried out for vaporization, precisely where the accumulation of lime originates.
  • This system defines a very effective cleaning system and the cleaning system includes a second actuator different from the steam regulator so that when it acts it allows the water to pass, thus avoiding the anti-drip system.
  • Some dosing systems incorporate a communication for the passage of air to the outside. This communication to the outside air allows the removal of air bubbles that may be trapped in the dosing unit and interrupt or slow down the passage of water. In this way the dosing is more stable.
  • the invention consists of a water dosing system according to the claims.
  • the invention defines a dosing system with a cleaning system and generally comprises an anti-drip system.
  • the cleaning system that avoids the anti-drip device and allows water to be introduced into the steam chamber, regardless of the temperature, is actuated by the actuator of the regulating device.
  • the invention defines a new and inventive solution in the known state of the art.
  • the water dosing system is designed for irons and other pieces of equipment with a steam chamber.
  • the steam chamber is fed by a water dosing valve.
  • the dosing valve comprises a zero steam position, where the needle is supported on the dosing valve seat, and a maximum steam position where the needle leaves the water passage completely free.
  • the system comprises a cleaning valve and a mobile actuator with the needle passing through it.
  • the needle causes the movement of the actuator, usually by means of a stop attached to the needle, arranged between the actuator and the dosing valve seat.
  • the needle comprises a cleaning position, above the maximum steam position, in which it pushes the actuator against the cleaning valve, disengaging it from the cleaning valve seat, i.e. opening the valve.
  • This cleaning valve comprises a return system, which may be a spring.
  • the examples of embodiments shown in the figures are based on a non-drip dosing system.
  • the cleaning system comprises a movable actuator (1) which is passed through by the needle (2) of the dosing system so that there is relative freedom of movement between them.
  • the needle (2) may slide freely through the actuator (1) during normal ironing operations. That is, from the closed position (no steam) which corresponds to the position of the needle (2) supported on the dosing valve (3) ( Figures 1 , 5 and 7 ), and the maximum steam position, which corresponds to a higher position of the needle (2) ( Figure 2 ).
  • FIG. 3 An additional position, shown in figure 3 , corresponds to the time when the cleaning is carried out. It can be seen that the needle (2) is further away from the dosing valve (3), allowing more water to pass through.
  • Figure 4 shows the signaling of these positions in an example of a control unit for the regulating device.
  • the needle (2) of the embodiments shown comprises a stop (4) at a point between the dosing valve (3) and the actuator (1).
  • the rise of the needle (2) causes the movement of the actuator (1) due to the stop (4), at least at the end of its travel until the mentioned cleaning position is reached.
  • the actuator (1) also comprises a lower extension (11) which is integrally connected to the cleaning valve (5) in such a way that the rise of the actuator (1) to the cleaning position also causes the rise of the cleaning valve (5) from the corresponding cleaning valve seat, leaving the cleaning water passage free.
  • the function of the cleaning valve (5) can be performed in several alternative ways.
  • one possible embodiment, shown in Figures 5 and 6 would be one in which the cleaning valve (5) is a valve specific for this purpose and has no other function.
  • such a cleaning valve can also consist of the anti-drip valve (6) as shown in Figures 7 and 8 .
  • Figure 5 shows the closed position of the cleaning valve (5) when it is independent of the anti-drip valve (6).
  • the user has placed the dosing actuator in the cleaning position, so the needle (2) has been raised and its stop (4) also pushes or pulls up the actuator (1) and its lower extension (11), which, as already said, is integrally connected to the cleaning valve (5), thus also causing the upward movement of said valve and, therefore, allowing water to enter the steam chamber (8).
  • Figures 7 and 8 show the same positions as in Figures 5 and 6 , but when the cleaning valve is formed by the anti-drip valve (6) itself.
  • the lower extension (11) of the actuator (1) is longer, but that it is also integrally connected to the anti-drip valve (6) so that the upward movement of said actuator (1), when pushed by the stop (4) of the needle (2), also pushes the anti-drip valve (6) upwards and allows the water to flow freely into the steam chamber (8).
  • the actuator (1) has the shape of a cylindrical tube (9) whose through hole is crossed by the needle (2) and where this cylindrical tube (9) is supported by a spring (10) which serves to ensure its return to the watertight closing position of the cleaning system when it is no longer required by the user. More specifically, as can be seen in some figures, especially numbers 5 and 6, this spring (10) rests at the bottom of the cylindrical tube (9) which constitutes the lower extension (11) of the actuator (1) and, at the top, it rests against the wall of the tank so that, in addition to ensuring the return of the actuator, it ensures that the anti-drip valve (5) remains closed against its seat until the user pulls the needle (2) up again and it, through the stop (4), overcomes its resistance.
  • the needle (2) it would be possible for the needle (2) to be integrally connected to the actuator (1) and therefore to dispense with the stop (4).
  • this possible embodiment would be less advantageous than the above-mentioned preferred one, since the vertical movement that would make its lower extension (11) integrally connected to the anti-drip valve (5), when accompanying the needle (2), would mean the sweeping of a considerable space that would need to be foreseen inside the apparatus, thus complicating its internal structure and/or increasing its size.
