Definitions

  • the invention relates to a method and device for dosing water in a steam chamber.
  • the invention may be used in the field of garment care.
  • the ironing steam rates for such irons are rather low in view that limited water is dosed into the steam chamber to avoid water accumulation and splashing in steam chamber.
  • Another type of device comprises a base connected to an iron via a hose.
  • a trigger When user wants steam to be generated by the device, user activates a trigger so that water is pumped into the steam chamber of the iron by an electrical water pump.
  • Many of such systems are provided with an external base containing the water reservoir and the water pump. Water is thus carried from the base to the iron via the hose.
  • water reservoir and pump can be arranged in the iron housing itself in case the device is a handheld device.
  • the iron has a relatively limited thermal mass, resulting in that the steam chamber of the iron quickly loses energy when water is dosed into, in particular if water flow rate is relatively high.
  • the steaming is thus quickly and significantly decreased over time because the steam chamber in the iron cannot maintain a sufficiently high temperature to allow water to evaporate quickly.
  • the method according to the invention is about controlling a garment care device, the garment care device comprising a steam chamber, a water pump, and a user trigger means to activate the water pump for dosing water in the steam chamber.
  • the method comprises the steps of:
  • This solution allows maximizing the water flow rate dosed into the steam chamber, by taking into account how the steam chamber has been used in the past, such as taking into account how much thermal energy has been accumulated in the steam chamber during a previous non-steaming period, and how much thermal energy has been dissipated by the steam chamber during a previous steaming period.
  • this solution allows obtaining a high steam generation repeatedly, and obtaining consistent steam generation every time steam is generated.
  • the invention also relates to a device comprising means to implement above method.
  • the invention also relates to a computer program comprising code instructions for carrying out the steps of the above method.
  • Fig.1 depicts a high level flow chart of the method according to the invention.
  • the method is about controlling a garment care device comprising a steam chamber, a water pump, and a user trigger means to activate the water pump for dosing water in the steam chamber.
  • the method comprises the steps of:
  • the user trigger means corresponds to an electromechanical switch, a digital switch, or a touch-sensitive key arranged on the garment care device.
  • Fig.2 illustrates an example of the actuation/deactivation of a user trigger means along the time according to the invention.
  • the actuation/deactivation of the user trigger means is represented by two states:
  • Instant t0 corresponds to the current time user actuates again the user trigger means with the goal that the device generates steam.
  • the previous OFF duration during which the user trigger means was not activated for the previous time is illustrated by the duration d OFF.
  • the previous ON duration during which the user trigger means was activated for the previous time is illustrated by the duration d_ON.
  • the method according to the invention aims to determine the water flow rate for the water pump starting from the current time t0.
  • Fig.3 depicts a more detailed flow chart of the method according to the invention. This flow chart further details what is performed in the step of determining 101 of Fig.1 .
  • the step of determining (101) comprises a step of comparing (301) the previous OFF duration (d_OFF) to a first duration threshold (THE1).
  • conditional check on the previous ON duration (d_ON) is illustrated by the decision block 303.
  • the values in the first range of values (R1) are larger than values in the second range of values (R2).
  • Fig.4 depicts a flow chart of the method according to the invention according to a preferred mode. This flow chart is based on the flow chart of Fig.3 . In addition to the flow chart of Fig.3 , it is planned that if the previous OFF duration (d_OFF) is larger than said first duration threshold (TH1), there is a step of associating (401) to the water flow rate a value selected in the first range of values (R1).
  • conditional check on the previous OFF duration (d_OFF) is illustrated by the decision block 402.
  • the user trigger means is continuously activated, and if the previous OFF duration (d_OFF) is larger than the first duration threshold (TH1), there is a step of associating (601) to the water flow rate a value selected in the first range of values (R1) for a first duration (D1) which is at the maximum equal to said second duration threshold (TH2).
  • the step of associating (601) is not illustrated in the figures.
  • the user trigger means is continuously activated, and if the previous ON duration (d_ON) is shorter than said second duration threshold (TH2), associating (602) to the water flow rate a value selected in the first range of values (R1) for a second duration (D2) which is at the maximum equal to the difference between said second duration threshold (TH2) and said previous ON duration (d_ON).
  • the step of associating (602) is not illustrated on a flow chart.
  • the user trigger means is continuously activated, and if said first duration (D1) has elapsed or said second duration (D2) has elapsed, there is a step of associating (603) to the water flow rate a value selected in a third range of values (R3).
  • the step of associating (603) is not illustrated on a flow chart.
  • the values in the third range of values (R3) are smaller than values in the second range of values (R2).
  • step 603 if the user trigger means is continuously activated after the method has entered in step 603, and after the water pump has been actuated with values of flow rate from said third range of values (R3) for more than a predetermined third duration (D3), there is a step of associating (604) to the water flow rate a value selected in the second range of values (R2).
