Specific implementation method:

A kind of optional position electronics water pot comprises kettle body 1, base 2, controller 3 and circuit 4, and described controller 3 is divided into controller 30 and reaches controller 31 down.Last controller 30 is established the bottom of sub-kettle body 1, is respectively equipped with in the annular power supply contact 302, the shared contact 303 of temperature sensor, dry combustion method temperature sensor contact 304 and vapor (steam) temperature sensor contact 305 outside contact 301, the power supply in the control seat 300 of last controller.End face at control seat 300 is provided with stator 307, is equipped with center contact 308 in the centre bore of control seat 300 and stator 303.Following controller 31 is formed base 2, comprises a shell 310, seat core 311, backplate 312, backplate spring 316, contact apparatus 313 and base plate 314.Contact apparatus 313 by two groups of power contact heads 3130, be located at the power supply spring 3131 on the power contact head, three groups of sensor contact 3132 and the touch spring 3133 be located on the sensor contact is formed, be located between base plate 314, seat core 311 and the backplate 312; Three groups of sensor contact 3132 match with the contact endoporus 3110,3111,3112 of seat core 311 respectively.Each contact is exposed by endoporus, contacts with each sensor contact.Also be provided with the center touch base 3134 that cooperates with center contact 308 at base plate 314 centers.Power contact head 3130 respectively be located at backplate 312 on power supply endoporus 3120,3121 cooperate, on controller seat 300 and stator 307, be respectively equipped with dry combustion method temperature sensor 309 vapor (steam) temperature sensors 3091 and the hot fuse 3092 of temperature, sensor is connected by lead between the two with each contact, be connected by lead between heat-generating pipe, Thermal Cutoffs and power supply contact, and join with power circuit.Backplate spring 316 is located between the seat core 311 and backplate 312 in the shell 310, is used for electrocution-proof protection.Be further to strengthen protection, in the intermediate cavity 3113 of the seat core 311 of controller 31 down, be provided with and make the self-locking device 315 that backplate 312 is stuck and depress.Self-locking device comprises self-locking body cover plate 3150, left locking key 3151, right locking key 3152 and self-locking spring 3154.

Operation principle:

1, when last controller inserts controller (during work).

At first copper contact 308 stretch in turn in the locking key 3151 and the centre bore of locking key 3152 in, because locking key centre bore single side face has one not over against the inclined-plane at center, locking key 3151 will be liked the horizontal component of copper contact 308 with locking key 3152 and make locking key 3151 and locking key 3152 relative to moving to the center like this, thereby its end will break away from and contact the restriction that cancellation moves up and down to backplate with backplate 312 like this.

Control seat 300 base section planes of then going up controller will apply downward power and give backplate 312 and make and remove a control outer ring outer shroud The whole control seat and can be inserted in down in the controller, controller is conducting state from making up and down: a, copper contact 308 conducting contacts 3134, and contact 3134 connects power ground; B, contact 301 and contact 3132 conductings, two poles in contact 302 and the contact 3130 conductings difference connection circuit plate; Thereby c, contact 305,304,303 are used for induced signal with three contact 3130 conductings of following controller respectively sends into control circuit.

2, when last controller leaves down controller (during inoperative).

At first contact 301 and contact 302 will leave contact 3132 and contact 3130 respectively, backplate moves under the effect of backplate spring 316 power, when copper contact 308 leaves locking key 3151 and locking key 3152 in turn, thereby backplate is pinned in the reverse horizontal movement under the effect of each locking key spring force of locking key 3151 and locking key 3152, like this with hand or general tool when pressing down backplate, thereby backplate can not move downward and can not make contact 3130 expose down control and prevent accidental shock, and contact 303,304,305 leaves the contact corresponding with it 3132 respectively then.

3, steam principle of induction.

When water is opened, a large amount of steam will from the steam pipe inner chamber flow to the vapor (steam) temperature sensor sensing to

Temperature enough back transmission signal gives control circuit with cut-out heating element power supply, and notice buzzer response prompting user water is opened.

4, dry combustion method and insulation temp probe principle of induction.

After anhydrous or water burns, the corrosion resistant plate bottom temp will rise, and the dry combustion method temperature sensor is passed to control circuit to this signal with cut-out heating element power supply after protection value when temperature rises.

When insulation, thereby this dry combustion method temperature sensor will transmit another or the several temperature signal is switched on or switched off for control circuit control heat-generating pipe.
