Fig. 2 is the electrical block diagram of the utility model one embodiment.
Fig. 3 is the sectional structure schematic diagram of another embodiment of the utility model.
Fig. 4 is the sectional structure schematic diagram of the utility model the 3rd embodiment.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Referring to Fig. 1, this electric cooker comprises that pot cover 1, pot body 2, outer pot 3, interior pot 4, heater 5 and temperature controller 6, and in the present embodiment, temperature controller 6 is a magnetic steel temperature limiter.
The pot cover 1 of electric cooker is articulated in the upper edge of pot body 2, be provided with outer pot 3 in pot body 2, pot 4 in being provided with in the outer pot 3, between interior pot 4 and outer pot 3, be provided with heater 5, heater 5 is fixed on outer pot 3 bottoms, be provided with temperature controller 6 and cover body 8 at heater 5 and outer pot 3 centers, temperature controller 6 passes outer pot 3 and is fixed on its bottom.Be provided with back-moving spring 7 between temperature controller 6 and the cover body 8, temperature controller 6 bottoms are provided with leg 6.1, and leg 6.1 passes cover body 8.Below temperature controller 6, also be provided with interior pot sense switch 10 by temperature controller 6 displacements control on off operating mode.
The course of work of this product is as follows: user in correct the placement pots 4 o'clock, interior pot gravity is subjected to displacement temperature controller 6 downwards, under temperature controller leg 6.1 active forces, transmission levers 9 rotates around swivel pin 12, thereby the pot sense switch touches part 10.1 in pressing down, 10 conductings of pot sense switch, power connection at this moment in making; Pot is 4 the time in removing, temperature controller 6 resets under the effect of back-moving spring 7, and 6.1 pairs of transmission levers of temperature controller leg, 9 downward active forces are cancelled, and interior pot sense switch touches part 10.1 and is not subjected to external force, an interior pot sense switch 10 automatically resets to off-state, and this moment, power supply was closed automatically.
Referring to Fig. 2, this product circuit course of work is as follows: temperature controller K1 connects with electric hot tray W, microswitch K2, Thermal Cutoffs FUSE and power supply AC, temperature controller K1 two ends are parallel with insulation indicator lamp L1 and current-limiting resistance R1, and heater W two ends are parallel with burner on light L2 and current-limiting resistance R2.Behind the interior pot of correct placement, microswitch K2 closure, the circuit turn-on operate as normal, during electric hot tray W heating, burner on light L2 is bright, and when electric hot tray W did not heat, L1 was bright for the insulation indicator lamp; As pot in not placing or when in electric cooker, removing interior pot that correctly places, the microswitch K2 disconnection that automatically resets, circuit disconnects, electric hot tray W can not heat, and indicator lamp L1, L2 do not work, so not only save electric resources, eliminate electric potential safety hazard, can also point out the user not place interior pot timely and effectively.
Referring to Fig. 3, in the present embodiment, be provided with stairstepping fixed support 11 ' in outer pot 3 bottoms, interior pot sense switch 10 is fixed on the lower end of fixed support 11 ', and interior pot sense switch 10 tops are provided with elastic switch and touch part 10.1; It is inconsistent that the elastic switch that temperature controller 6 bottom supports 6.1 pass cover body 8 and interior pot sense switch 10 tops touches part 10.1.The pot sense switch touched part 10.1 in it was directly controlled by temperature controller leg 6.1 conducting or disconnection.
Referring to Fig. 4, in the present embodiment, pot sense switch 10 in the bottom of temperature controller 6 bottom supports 6.1 is fixed with, interior pot sense switch 10 bottoms are provided with elastic switch and touch part 10.1; Be provided with L shaped fixed support 13 in outer pot 3 bottoms, in fixed support 13 1 ends are arranged on pot sense switch 10 belows and with elastic switch to touch part 10.1 inconsistent.
The present embodiment course of work is as follows: user in correct the placement pots 4 o'clock, interior pot gravity is subjected to displacement temperature controller 6 downwards, drive temperature controller leg 6.1 effect downwards, because interior pot sense switch 10 is arranged on the bottom of leg 6.1, pot sense switch 10 also moves downward in this moment, it is inconsistent with fixed support 11 that elastic switch touches part 10.1, connects power work.Otherwise deenergization then.
