[39] according to Fig. 6 a and 6b, selector 17 is connected on the conversion equipment (dispositif de commutation) of steam and electricity via a connecting rod 5, described conversion equipment comprises a steam distribution valve 6, described steam distribution valve 6 has: a steam inlet 60, it connects an electrically operated valve 7 in the upstream, this electrically operated valve 7 is placed in the exit of the basin ware of generator; With two steam (vapor) outlets 61,62, they are connected on the conduit of the pipeline of supplying with into flatiron 2 and flatiron brush 3 20,30.

[40] valve 6 comprises a pipe box (manchon) 63, described pipe box 63 is driven in rotation via connecting rod 5, and the connection via a screw type is connected on the valve body 6, the outer surface of valve body has a spiral ribs 64, it is engaged with in the pipe box 63 inner helicla flutes that form, thereby the rotation of pipe box 63 is accompanied by the translational motion of described spiral ribs 64.

[41] conversion equipment also has two switch 66a, 66b, it is started by the boss 65a, the 65b that are arranged on pipe box 63 outer surfaces, described boss 65a, 65b are configured to make the first switch 66a only to be activated when selector 17 is positioned at the use location of the flatiron 2 shown in Fig. 6 a, and second switch 66b only is activated when selector 17 is positioned at the use location of the flatiron brush 3 shown in Fig. 6 b.

[42] described switch 66a, 66b are connected on the control module 100, the described control module that is shown schematically on Fig. 6 a and the 6b comprises a microprocessor, and described microprocessor can be inferred the position of valve 6 and selector 17 from the starting state of switch 66a, 66b.

[43] according to Fig. 7 a---it illustrates the profile of valve 6 when selector 17 is in the use location of flatiron 2, valve inlet 60 leads to a cylindricality steam distribution chamber 67, described steam distribution chamber is extended by the duct of minor diameter (al é sage) 68a, 68b more at place, each end, the first duct 68a is connected with delivery outlet 61 on being connected flatiron connecting line 20, and the second duct 68b is connected with delivery outlet 62 on the connecting line 30 that is connected flatiron brush 3.

[45] according to Fig. 7 b, when selector 17 was diverted the use location of flatiron brush 3, pipe box 63 retreated rotation on the main body of valve 6, thereby caused moving of piston 69, and make the first packing ring 69a injection pass the first duct 68a, thereby steam no longer can flow to flatiron 2.On the contrary, the second packing ring 69b thereby in the distributor chamber 67 of bigger diameter, move, thereby make steam can pass the second packing ring 69b around, and flow to flatiron brush 3 by hole 62.

[46] more particularly, according to the present invention, control module 100 is controlled the electrically operated valve 7 in the basin ware exit that is arranged on generator, thereby in certain working time section---just flatiron 2 or flatiron brush 3 are not powered selecteed accessory in this working time section, prevention provides steam for flatiron 2 or flatiron brush 3, is not powered.Such security performance is avoided any injection of condensate liquid, guarantees that simultaneously the vaporization chamber 22 of flatiron or the vaporization chamber 32 of flatiron brush are on the sufficient temp, and described sufficient temp can make the condensate liquid evaporation that may be present among the

pipeline

20,30.

[47] for instance, the microprocessor of control module 100 can be according to algorithm shown in Figure 8, the opening of the electrically operated valve 7 of the basin ware of control generator.

[48] according to shown in accompanying drawing, control module 100 detects flatiron 2 at phase I E1 and with which accessory among the flatiron brush 3 is chosen by the user.Determining of selected accessory can realization simply from the information that switch 66a, 66b are linked up.

[49] therefore control module 100 is measured time T m in second step e 2, and described time T m is meant from the end elapsed time of the previous stage that selected

accessory

2,3 uses.For the operational phase of accessory, can be regarded as that ironing apparatus is activated and selector 17 is in stage of the position corresponding with described accessory.

[50] in third step E3, control module 100 can be checked Tc preheating time that uses accumulative total previous stage at accessory _S-1Whether be enough to make the preheating total time of accessory to reach 120 seconds.

[51] if accumulative total Tc preheating time in a stage before use _S-1Be lower than 120 seconds, so control module 100 step e 3 ' in finish preheating to accessory, described step e 3 ' in, accessory carries out preheating in a period of time Tc, Tc is corresponding to reaching the preheating time that lacked 120 seconds total preheating time.In described Tc warming up period, a light emitting diode 18 glimmers on the front surface of pedestal 1, is in the heating period in order to show selected accessory to the user.Reaching additional warming up period in limited time, control module 100 enters step e 4.

[52] opposite, if reached 120 seconds preheating time in the previous stage that accessory uses, therefore control module 100 directly enters step e 4, in described step e 4, after the previous stage of using from accessory through time T m and be fixed as a threshold of 5 minutes as shown in the figure the example.

[53] if time T m is lower than 5 minutes, in step e 5, in case control module its when receiving the control instruction of

trigger

23,33 of

accessory

2,3, just allow to open immediately motor-driven valve.

[54] opposite, if cumulative time Tm greater than 5 minutes, control module therefore enter supplementary heating step e 4 to accessory ', be used to compensate the cooling of the accessory that brings because of the thermal loss in the non-operational phase of accessory.

[55] described stage E 4 ', accessory is heated in prolongation Ts, prolongation Ts equals minute quantity that Tm exceeds 5 minutes threshold values and multiply by COEFFICIENT K _A, COEFFICIENT K _ATo implement the second number of supplementary heating corresponding to exceeding accessory stops after 5 minutes threshold values each minute.

[56] yet, if the time T s that obtains by described calculating greater than 120 seconds, the supplementary heating time will be limited in Ts=120s, necessary initial preheating time when this is cooled corresponding to accessory.In the supplementary heating stage, diode 18 is in the heating period in the front surface flicker of pedestal 1 in order to show selected accessory to the user.When the time limit that arrives supplementary heating, control module 100 enters step e 5, and in step e 5, control module allows opening of electrically operated valve 7 according to the control of the

trigger

23,33 of accessory.

[57] certain, COEFFICIENT K _AThe heating power that depends on the hot block (masse thermique) and the accessory of choosing.For example, COEFFICIENT K _AValue be K for flatiron brush 3 _A=1s/min is K for flatiron 2 _A=1.25s/min.

[58] therefore, if the accessory of choosing is a flatiron brush 3, beginning elapsed time Tm from the previous stages that flatiron brush 3 uses is 9 minutes, will be for 4 seconds and replenish preheating time Ts, and control module 100 allows steam to carry to pipeline 30 afterwards.

[59] the flatiron electrical equipment of so implementing has the advantage that a steam transmits control module, described steam transmits control module can improve the security that electrical equipment uses greatly, and especially can reduce the risk that the user is scalded by the boiling hot condensate liquid of sending out from flatiron or flatiron brush bottom steam delivery outlet.In fact, guarantee that the condensate liquid that is present in connecting line is evaporated in case the vaporization chamber of described accessory has insufficient time to, the control module of generator can stop delivery of steam to pass the accessory of new selection.Therefore, when if the user presses the trigger of selected accessory, control module will be cancelled the instruction that electrically operated valve is opened, up to arriving the additional preheating time limit that control module calculated, and the diode on the pedestal begins flicker, needs certain stand-by period to remind the user.

[60] opposite, in the example of foregoing description, if accessory is used in less than 5 minutes recently, therefore control module opens electrically operated valve at once, so that steam is transferred when pressing trigger.

[61] last, being also advantageous in that of electrical equipment, it is very convenient that the accessory that is made of flatiron and flatiron brush uses, and flatiron always is connected the generator pedestal with the flatiron brush, and therefore can just can be used without complicated operations.On the flatiron pipeline, have a Winder, security and work efficiency in the time of can greatly improving electrical equipment and use, simultaneously when flatiron or movable electrical appliances, avoid pipeline messy be wound.

[62] certain, the present invention be not limited only to foregoing description with shown in the embodiment that only provides with way of example.The feelings subordinate who does not exceed protection of the present invention field, especially, can make amendment to the present invention based on different element formations or the viewpoint of replacing by equivalent technologies.

[63] therefore, preheating and heat algorithm also only provide with way of example.Especially, for considering more parameter, described algorithm can be made amendment.
