For operation steam iron 1, the heater (not shown) that is arranged in the steam iron base plate 3 is adjusted to a predetermined value, open the external steam generator.In case the external steam generator produce steam and in case above-mentioned valve externally open in the steam generator, steam lead 5, feed line 7 with and delivery channel 11 vaporizer 8 that upwards arrives steam discharge valve 12 will be under the pressure.
Leverage 28 makes valve rod 31 move freely along the direction of opening of steam discharge valve 12.
Act on the power of valve tappet 15 if the overvoltage that is full of in the vaporizer 8 surpasses spring element 16 along closing direction, steam discharge valve 12 will be opened automatically and discharge these overvoltages by means of conduit 18.In this way, overvoltage dangerous in the vaporizer 8 will be avoided.Can set limiting pressure by the elastic force of regulating spring element 16, surpass its steam discharge valve 12 and just will open automatically.
For manual unlocking steam discharge valve 12, key 27 must move along the direction of handle 2.Valve tappet 15 is opened the mobile degree that depends on that key 27 moves towards handle 2 of direction along steam discharge valve 12.Therefore, steam discharge valve 12, can measure the amount of pressure of discharging from steaming chamber 8 by moving of valve tappet 15 by this metering valve also as metering valve.Because it is mobile that the overvoltage in the vaporizer 8 is being supported to open by the power of antagonistic spring element 16, therefore, the control in the metrological operation process is easy to carry out.
Under the open mode of steam discharge valve 12, steam is sent to sprayer 22 by conduit 18.If steam humidification unit 20 is opened, then the steam that flows fast at this place will suck water and/or add moist steam from water tank 24 with the form of microatomization.The moist composition that is applied to the steam on the sodolin that will press can accurately be regulated in this way.
Subsequently, steam arrives the settling chamber 19 of heating by steam iron base plate 3; Be evenly distributed to steam hole 4 from above-mentioned settling chamber 19.
Because steam iron base plate 3 is made of the metal material with high thermal conductivity and by the heating of unshowned heating element heater, and because whole steam guide elements of steam discharge valve 12 and steam humidification unit 20 all are to be made by the material with high thermal conductivity, therefore, steam is guided in the conduit of forcing heat enduringly.This measure also is used to avoid the too early condensation of steam.
When the clothes of exquisiteness being pressed, exist from the danger of the high-temperature steam of external steam generator supply in idle period of time total condensation the vaporizer 8 that is in low temperature with low ironing temperature and with dry steam.In this case, when starting steam discharge valve 12, not only steam but also condensate also will be discharged from the steam hole the steam iron base plate 34.
For avoiding this situation, can in steam iron 1 other becomes the handle 2 of example, a microswitch (not shown) be set.When operation metering units 26 or key 27, this microswitch automaticallyes switch, and the steam valve on the starting external steam generator, thereby makes steam enter vaporizer 8 from the external steam generator conduit 5 of flowing through, and the steam discharge valve 12 of flowing through arrives steam holes 4.Microswitch is regulated, made it before steam discharge valve 12 is opened, open the steam valve of external steam generator.Because the switching point that this time of microswitch shifts to an earlier date, the steam valve of external steam generator will always be opened before steam discharge valve 12 is opened.
By this measure, can prevent that steam from stopping and condensation in vaporizer 8.The flatiron of this embodiment is specially adapted to responsive sodolin or the clothes of Low Temperature Steam flatiron.
