The steam generator includes a first layer and a second layer and at least one heating element sandwiched between the first layer and the second layer. The first layer and the second layer define a steam flowpath that is configured such that steam flows back and forth between the first layer and the second layer before exiting the steam generator. ## Claims ### Claim 1 A garment steaming device, comprising: a housing having a reservoir for containing liquid therein; a head portion connected to the housing; a steam generator contained within the head portion, the steam generator being in fluid communication with the reservoir for generating steam from the liquid contained in the reservoir; and a control unit configured to control the pumping rate of the pump; wherein the control unit is configured to control the pump to provide a first flow rate of fluid to the steam generator during a preheating mode of operation of the garment steaming device, and to control the pump to provide a second flow rate of fluid to the steam generator after the preheating mode of operation is complete; and wherein the first flow rate is less than the second flow rate. ### Claim 2 (depends on 1) The garment steaming device of claim 1, the control unit is configured to control the pump to gradually increase the flow rate of fluid to the steam generator from the first flow rate to the second flow rate. ### Claim 3 (depends on 1) The garment steaming device of claim 1, wherein: the steam generator includes a primary heating element and a secondary heating element; wherein the control unit configured to regulate a steam temperature generated by the steam generator by controlling at least one of a power level of the primary heating element and/or the secondary heating element, and/or controlling the flow rate of fluid from the reservoir to the steam generator. ### Claim 4 (depends on 3) The garment steaming device of claim 3, wherein: the control unit is configured to regulate the steam temperature by operating the primary heating element at a constant power and varying a power level of the secondary heating element. ### Claim 5 (depends on 4) The garment steaming device of claim 4, further comprising: a first control device for controlling the primary heating element; and a second control device for controlling the secondary heating element. ### Claim 6 (depends on 5) The garment steaming device of claim 5, wherein: the first control device is a mechanical thermostat; and the second control device is a NTC thermistor with a relay or triac. ### Claim 7 (depends on 1) The garment steaming device of claim 1, wherein: the steam generator includes a main water bath and a secondary water bath, the main water bath and the secondary water bath being in fluid communication with the reservoir for receiving liquid therefrom; wherein the secondary water bath has a capacity that is less than a capacity of the main water bath to facilitate rapid generation of steam. ### Claim 8 (depends on 7) The garment steaming device of claim 7, wherein: the secondary water bath is positioned in close association with a heating element of the steam generator. ### Claim 9 (depends on 7) The garment steaming device of claim 7, wherein: at least one of the main water bath and the second water bath includes a foam metal material. ### Claim 10 A method of operating a garment steaming device, comprising the steps of: providing a flow of fluid from a reservoir to a steam generator at a first flow rate during a first operational period; and increasing the flow of fluid from the reservoir to the steam generator to a second flow rate during a second operational period. ### Claim 11 (depends on 10) The method according to claim 10, wherein: the first operational period is a preheating mode of operation of the garment steaming device. ### Claim 12 (depends on 10) The method according to claim 10, wherein: the second flow rate is substantially constant. ### Claim 13 (depends on 11) The method according to claim 11, wherein: increasing the flow of fluid occurs substantially continuously until the preheating mode of operation is complete. ### Claim 14 (depends on 13) The method according to claim 13, further comprising the step of: regulating a steam temperature generated by the steam generator by controlling at least one of a power level of a primary heating element and/or a secondary heating element, and/or controlling the flow rate of fluid from the reservoir to the steam generator. ### Claim 15 (depends on 14) The method according to claim 14, wherein: the control unit is configured to regulate the steam temperature by operating the primary heating element at a constant power and varying a power level of the secondary heating element. ### Claim 16 (depends on 15) The method according to claim 15, wherein: the garment steaming device includes a first control device for controlling the primary heating element and a second control device for controlling the secondary heating element. ### Claim 17 (depends on 16) The method according to claim 16, wherein: the first control device is a mechanical thermostat; and the second control device is a NTC thermistor with a relay or triac. ### Claim 18 (depends on 10) The method according to claim 10, wherein: the steam generator includes a main water bath and a secondary water bath, the main water bath and the secondary water bath being in fluid communication with the reservoir for receiving liquid therefrom; wherein the secondary water bath has a capacity that is less than a capacity of the main water bath to facilitate rapid generation of steam.
