Estimating the term…
A garment steaming device includes a steam generator (20) having a heater (22) and an ironing surface (32) against which a fabric of a garment is locatable. An intermediate section (50) is disposed between the steam generator and the ironing surface to transfer heat from the steam generator to the ironing surface so that the ironing surface is indirectly heated by the steam generator via the intermediate section. The operating temperature of the ironing surface is not user selectable during use. Furthermore, the intermediate section is configured to have a thermal transmittance so that, during use, heat transfer from the steam generator to the ironing surface is controlled and the temperature of the ironing surface is maintained between 90° C. and 155° C. when the ironing surface is located against a fabric in each of a stationary condition and a moving condition.
A garment steaming device comprising a steam generator having a heater, an ironing surface against which a fabric of a garment is locatable, and an intermediate section configured to have a thermal transmittance and disposed between the steam generator and the ironing surface to transfer heat from the steam generator to the ironing surface so that the ironing surface is indirectly heated by the steam generator via the intermediate section, wherein the operating temperature of the ironing surface is not user selectable during use and the intermediate section is configured to have a thermal transmittancethat, during use, controls the heat transfer from the steam generator to the ironing surface to maintain the an operating temperature of the ironing surface between 90° C. and 155° C.when the ironing surface is located against a fabric in each of a stationary condition and a moving condition relative to the fabric, wherein the intermediate section is further configured to have at least one selected from the group consisting of (i) a fixed thermal transmittance between 75 W/m2K and 125 W/m2K and (ii) a variable thermal transmittance of a variable heat conductivity material, wherein the variable heat conductivity material is configured to vary its thermal transmittance by at least 100% over a change in temperature of the variable heat conductivity material of 50° C.
A garment steaming device comprising a steam generator having a heater, a motion sensor configured to detect the operating condition of the garment steaming device, an ironing surface, and a controller, wherein the controller is configured to operate the heater to maintain the steam generator at a first temperature range when no motion of the garment steaming device is detected by the motion sensor and the ironing surface is located against a fabric, and at a second temperature range when motion of the garment steaming device is detected by the motion sensor and the ironing surface is located against a fabric, further comprising and an intermediate section disposed between the steam generator and the ironing surface to transfer heat from the steam generator to the ironing surface so that the ironing surface is indirectly heated by the steam generator via the intermediate section, wherein the intermediate section is configured to have at least one selected from the group consisting of (i) a fixed thermal transmittance between 75 W/m2K and 125 W/m2K and (ii) a variable thermal transmittance of a variable heat conductivity material, wherein the variable heat conductivity material is configured to vary its thermal transmittance by at least 100% over a change in temperature of the variable heat conductivity material of 50° C.
A method of operating a garment steaming device having a steam generator with a heater, an ironing surface, and a motion sensor configured to detect the operating condition of the garment steaming device, the method comprising operating the heater to maintain the steam generator at a first temperature range when no motion of the garment steaming device is detected by the motion sensor and the ironing surface is located against a fabric, and operating the heater to maintain the steam generator at a second temperature range when motion of the garment steaming device is detected by the motion sensor and the ironing surface is located against a fabric, wherein an intermediate section is disposed between the steam generator and the ironing surface to transfer heat from the steam generator to the ironing surface so that the ironing surface is indirectly heated by the steam generator via the intermediate section, wherein the intermediate section is configured to have at least one selected from the group consisting of (i) a fixed thermal transmittance between 75 W/m2K and 125 W/m2K and (ii) a variable thermal transmittance of a variable heat conductivity material, wherein the variable heat conductivity material is configured to vary its thermal transmittance by at least 100% over a change in temperature of the variable heat conductivity material of 50° C.
