Definitions

  • This invention relates to a method for controlling operation of a steam iron, more particularly to a method for controlling amount of steam ejected by the steam iron.
  • a steam iron is usually controlled by a steam switch that enables and disables the steam iron to eject steam.
  • the steam iron continuously ejects steam as long as the steam switch is turned on, and the steam ejected from the steam iron may condense into water on a sole plate of the steam iron.
  • the amount of steam ejected by the steam iron is usually constant, which may make the cloth to be ironed too damp, and thus lengthen time for drying the cloth.
  • WO 01/55496 A2 describes an electric steam iron having an electrically heated soleplate, said soleplate having at least one steam vent, a controllable steam generator for supplying steam to the at least one steam vent, and control means for controlling the steam generator, wherein the steam iron further comprises a temperature sensor means for sensing the temperature of the soleplate, said temperature sensor means in use supplying a temperature dependent signal to the control means and the control means being adapted to activate the steam generator in accordance with a predetermined steam pattern comprising at least a first phase of a first predetermined duration, in which steam is supplied at a substantially constant peak steam rate, and at least a second phase, in which steam is supplied at a substantially constant lower steam rate, ; wherein at least said peak steam rate depends upon the temperature of the soleplate.
  • GB 2 456 303 A describes a steam iron which includes a control device adapted to give an initial steam event through a soleplate, followed by a subsequent steam event of reduced flow rate and/or reduced volume.
  • the iron includes a water tank along with the heatable soleplate.
  • the control device may separate initiation of the initial and subsequent steam events by a determinable time interval. The time interval may be determined by the output of a temperature sensor.
  • the steam events may be a steam burst.
  • the iron is also used in a method of steaming a steam iron on demand by providing an initial steam burst and a subsequent steam emission of reduced flow rate.
  • the steam iron includes a steam generating unit for generating and ejecting steam, a controller for controlling operation of the steam generating unit, and a switch for activating the steam generating unit to eject steam.
  • the method for controlling operation of a steam iron includes the steps of independent method claim 1 or independent method claim 12.
  • step S01 upon the switch 34 being turned on, the controller 33 starts timing a first time period, and enables the pump 32 to draw water to the sole plate 31 to eject a first amount of steam per unit time until the first time period has elapsed.
  • the first time period may vary from 5 to 7 seconds in different embodiments, and preferably, is 6 seconds.
  • the first amount of steam per unit time may be varied from 80g to 150g per minute in different embodiments, and preferably, is 90gperminute.
  • step S02 the controller 33 determines whether the first time period has elapsed. The flow goes to step S03-1 when it is determined that the first time period has elapsed, and goes to step S03-2 when otherwise.
  • step S03-1 the controller 33 determines whether the switch 34 is still turned on when the first time period has elapsed. The flow goes to step S04 when it is determined that the switch 34 is still turned on, and goes to step S05-1 when otherwise. Subsequently, in step S04, the controller 33 enables the pump 32 to draw water to the sole plate 31 to eject a second amount of steam per unit time when the switch 34 is turned on.
  • the second amount of steam per unit time may vary from 30g to 50g per minute in different embodiments, and preferably, is 40g per minute.
  • step S05-1 When the controller 33 determines that the switch 34 is turned off in step S03-1, the controller 33 starts timing a second time period in step S05-1.
  • the second time period is longer than the first time period and may vary from 11 seconds to 13 seconds in different embodiments, and preferably, is 12 seconds.
  • stepS06-1 the controller 33 determines whether the switch 34 is turned on again. The flow goes to step S07-1 when it is determined that the switch 34 is turned on, and step S06-1 is repeated when otherwise.
  • step S07-1 the controller 33 determines whether the second time period has elapsed when the switch 34 is turned on again. When the second time period has not elapsed, the flow goes to step S04. That is to say, the controller 33 enables the pump 32 to draw water to the soleplate 31 to eject the second amount of steam unit time when the switch 34 is turned on again within the second time period. Otherwise, when the controller 33 determines that the second time period has elapsed in step S07-1, the flow goes back to step S01 and the controller 33 re-starts timing the first time period.
  • step S03-2 the controller 33 determines whether the switch 34 is still turned on within the first time period. The flow goes back to step S01 when it is determined that the switch 34 is turned on, and goes to step S05-2 when otherwise. For example, assuming that the first time period is 6 seconds, the switch 34 is turned off when 2 seconds has elapsed, and is turned on again when 5 seconds has elapsed. The controller 33 enables the pump 32 to draw water to the sole plate 31 to output the first amount of steam per unit time for 1 second after the switch 34 is turned on again at the fifth second. Additionally, the controller 33 disables the steam generating unit to eject steam when the switch 34 is turned off.
  • step S05-2 the controller 33 starts timing the second time period when the switch 34 is turned off within the first time period. Subsequent to step S05-2, in step S06-2, the controller 33 determines whether the switch 34 is turned on again. The flow goes to step S07-2 when the switch 34 is turned on again, and step S06-2 is repeated when otherwise. In step S07-2, the controller 33 determines whether the first time period has elapsed when the switch 34 is turned on again. When the first time period has not elapsed, the flow goes back to step S01. Otherwise, the flow goes to step S08 when the first time period has elapsed.
  • step S08 the controller 33 determines whether the second time period has elapsed. When the second time period has not elapsed, the flow goes back to step S04. That is to say, the controller 33 enables the pump 32 to draw water to the sole plate 31 to eject the second amount of steam per unit time when the first time period has elapsed and the switch 34 is turned on again within the second time period. For example, assuming that the first time period is 6 seconds and the second time period is 12 seconds, the switch 34 is turned off when 3 seconds have elapsed, and is turned on again when 6 seconds have elapsed, which starts timing the second time period. As a result, the controller 33 enables the pump 32 to draw water to the sole plate 31 to eject the second amount of steam per unit time.
  • step S08 When it is determined in step S08 that the second time period has elapsed, the flow goes back to step S01, i.e. , the controller 33 enables the steam generating unit to eject the first amount of steam per unit time when the switch 34 is turned on again after the second time period has elapsed.
  • the method for controlling operation of the steam iron 3 enables the steam iron 3 to first eject a relatively large amount of steam, i.e. , the first amount of steam per unit time, to soften the cloth to be ironed. Then, the steam iron 3 ejects the second amount of steam per unit time that is less than the first amount of steam per unit time so as to prevent the cloth from being too damp when the switch 34 is still turned on after the first time period has elapsed.
  • steam ejected by the sole plate 31 in the first time period can evaporate properly while the sole plate 31 irons the cloth.
