Definitions

  • the present invention relates to ironing apparatus comprising a steam generator.
  • the housewife does not have at her disposal a fixed production facility for steam generally uses generators which most often include a boiler producing saturated steam, especially in heaters ironing. In the latter the steam is produced under pressure and the distribution is controlled by a solenoid valve, so that relaxed at the atmospheric pressure and after passing through the distribution chamber of the soleplate of iron at high temperature, the steam is in the superheated state. We see so although the simplest generators don't control the steam quality.
  • Patent US4498254 shows an ironing installation where compressed air transports a mist of silicone oil intended to facilitate the sliding of ironing surfaces on the laundry. But such an installation is not transferable to domestic use.
  • Patent FR2771424 shows an iron comprising a device for textile adjuvant spray. But the additive is transported by water, which strongly moistens the treated support and is not suitable in many cases for use, for example to treat glass surfaces without leaking or to iron laundry that is still wet.
  • Patent FR2785975 shows a steam generator which, in one version, has an instant boiler and a circuit for adding water mist to the steam, allowing control of the quality of steam. But the circuit is not not intended to receive an additive.
  • the object of the following invention is an improved ironing apparatus, using a such a generator, which overcomes these drawbacks.
  • an ironing device comprising an iron and a steam generator which includes series a water tank, a first electric pump, a boiler, a mixing and atomizing device, a pipe for connection to the iron, and on the other hand at least one additional circuit composed by a tank for liquid additive in series with a second electric pump connected to the mixing and atomizing device, remarkable in that the iron includes a distributor directing the steam produced in two different circuits depending on whether or not it carries an ironing additive.
  • the additive can be a liquid or a solution or an emulsion, for example a perfumed solution or a highly diluted soluble silicone oil.
  • the device mixing and atomizing which can be a simple T connection, being in downstream of the boiler, the additive is not in contact with hot walls and does not not deteriorate.
  • the boiler is of the type where the water evaporates almost instantaneously.
  • the instant boiler can be dimensioned to allow the production of a dry steam which can then be made more humid to adapt to all possible uses.
  • the two pumps which can be started separately, can produce steam with or without additive on demand, which can be referred as appropriate in two different circuits of the device receiving the steam.
  • the generator comprises an anti-scale cartridge in the water circuit upstream of the boiler.
  • the generator comprises a circuit introducing a fog of water in the steam.
  • This circuit allows the control of the quality of the steam by making it more or less close to a state of saturation. This circuit is particularly useful when the generator is used with an iron. Indeed the steam distributed by the soleplate may be slightly overheated, which removes part of it efficiency. Adding water to the vapor solves this problem.
  • the generator includes a rapid purge circuit.
  • This circuit consists of a solenoid valve allowing the return of steam to the water tank when the water pump stops. Vapor pressure drop is then instantaneous and the user notes a good reactivity of the system.
  • Figure 1 is the diagram of a first version of a generator according to the invention that a first device such as an iron uses.
  • Figure 2 is the diagram of a second version of a generator according to the invention used with an iron.
  • Figure 3 is the diagram of a third improved version of a generator according to the invention used with an iron.
  • the generator 1 comprises a water tank 2 having a filling opening 21, an electric pump 3 drawing water from the water tank 2 through an anti-scale cartridge 22 and injecting it into a boiler 4 heated by an electric heating element 41 and temperature regulated.
  • the boiler 4 is of the instant vaporization type.
  • To the outlet of the boiler 4 the steam passes through a mixer 5 before being directed to a user device 7 via a flexible connection pipe 6.
  • the generator further comprises a liquid additive reservoir 8 having a filling orifice 81, an electric pump 9 drawing the additive and injecting it into the mixer 5.
  • the mixer 5 is a Y-connector where the vapor circulating at high speed atomizes and entrains the liquid additive in the form of a mist.
  • the appliance is for example an iron, and water is used as an additive in tank 8.
  • the boiler 4 of the generator 1 heats up to its temperature of setpoint.
  • the heating is rapid because the boiler is of the instant spray and does not contain water.
  • the user can grab the iron 7, and with an appropriate command put on the way the pump 3.
  • the steam then arrives at the iron 7 to produce its effect there.
  • the user can also simultaneously with a second command iron 7 switch on pump 9.
  • Water drawn from tank 8 arrives at mixer 5.
  • the vapor which circulates at high speed atomizes it and the drive in the device 7 where the humidified steam produces a more pronounced effect.
  • the mass flow rate of the added water being lower than that of the steam, pump 9 is clocked quickly but with a duty factor different from that of pump 3.
  • a duty factor different from that of pump 3.
  • generator 1 further comprises a rapid purge circuit and a circuit for humidify the steam and make it closer to saturated steam.
  • the circuit of rapid purge includes a solenoid valve 10 connected to the boiler 4 and to the tank 2. This solenoid valve opens for a predetermined time each time pump 3 stops.
  • the steam humidification circuit includes a pump 11 which can draw water from the water tank 2 and inject it into the mixer 5.
  • the liquids powered by pumps 9 and 11 arrive at the mixer 5 which preferably has several liquid inlets.
  • the pumps have different average flow rates either because they are of size different, either because the flow is controlled by a calibrated nozzle, or because they are clocked with a different walk factor. In neighboring version liquids from the same pumps are grouped together within the same line before entering the mixer 5.
  • the user device 7 is a steam iron. Iron has on the one hand of a circuit where the vapor leaves the device by orifices located under the sole in order to moisten the laundry, and on the other hand a spraying circuit comprising a nozzle 71 located at the front of the device. On iron 7 the user has a control 72 starting the water pump 3 and directing the steam towards the orifices of the soleplate, and of a control 73 putting simultaneously running the pump 3 and the additive pump 9 at the same time let it direct the steam towards the nozzle 71.
  • the iron 7 and the boiler 4 heat up quickly to their set temperatures.
  • the user can then iron.
  • the pump 3 and the pump 11 start up, injecting water from tank 2 into the boiler instant 4 on the one hand and in the mixer 5 on the other hand.
  • the steam produced passes through the mixer 5 by atomizing the water which arrives from the pump 11 and is moistening. Then the steam follows the pipe 6, arrives at the iron 7 which la distributes on the linen, in a slightly overheated state, through the holes of its sole 74.
  • the steam generator 1 comprises several additive tanks 8.8 ', 8 ", each associated with an electric pump 9.9', 9". Each tank can receive a different additive.
  • a switch not shown allows the user to choose the tank and the pump, therefore the additive, which will be used when using the spray command 73.
  • the operation is the same as in the previous example, but the user may successively use several adjuvants in the same session ironing by selecting them with the switch.
