Technical scheme of the present invention is not limited to be applied to electric cooker, can be applied to any realization steaming or boil the household electrical appliance of function.
For making the object of the invention, technical scheme and advantage clearer, will combine accompanying drawing that embodiment of the present invention is done to describe in detail further below.
Embodiment one
Fig. 1 is the circuit controling drawing of the heating control apparatus in the embodiment of the invention one.In Fig. 1, N-L is a power supply, and FU is a thermal fuse-link, and R01 is a heat-generating disc; R1 is first current-limiting resistance, and DX1 is a burner on light, and T1 is a temperature controller, and TK is a timer switch; R02 is heating board (being called the heat retaining and exothermal plate again), and R2 is second current-limiting resistance, and DX2 is incubated pilot lamp.
Among Fig. 1, burner on light DX1 connects with the first current-limiting resistance R1 and has composed in parallel heater circuit with heat-generating disc R01 again.Insulation pilot lamp DX2 connects with the second current-limiting resistance R2 and has composed in parallel thermal circuit with heating board R02 again.Power supply, thermal fuse-link FU, heater circuit and thermal circuit are connected successively and are formed the loop.Timer switch TK is parallelly connected with thermal circuit.The timer switch TK here can adopt the prior standard part; Timing motor (representing with " M " among the figure) and switch by series connection are formed; This timer switch TK its switch closure when being provided with timing; Its timing motor can carry out countdown under the driving of electric current, its switch breaks off when timing is made zero.The first temperature controller T1 is parallelly connected with the timing motor of timer switch; The first temperature controller T1 breaks off when temperature rises to first ceiling temperature, when temperature drops to first lower limit temperature, connects.Thermal fuse-link FU played superheat protecting function to circuit when temperature control device loses efficacy.
The principle of work of the circuit controling drawing of device shown in Figure 1 is following:
A1, under the condition of power connection; After the switch of timer switch TK is rotating closed; Electric current forms a loop through the switch and the first temperature controller T1 of thermal fuse-link FU, heater circuit, timer switch TK, and the heat-generating disc R01 that is arranged at the bottom of a pan begins heating, and burner on light is bright.
A2, first temperature controller T1 disconnection when cooking bottom temperature reaches the ceiling temperature point of the first temperature controller T1; This moment, electric current formed the loop through the parallel circuit of thermal fuse-link, heater circuit and thermal circuit and timer switch TK; Get into keeping warm mode; Be incubated that pilot lamp DX2 is bright this moment, the timing motor of heat retaining and exothermal plate R02 heating, timer switch TK begins to rotate, timer begins countdown.
Because the heat that heat-generating disc produces is directly proportional with the electric current of flowing through, under keeping warm mode, heating board R02 resistance is bigger on the loop; Therefore electric current is less on the loop; The heat also less (can ignore) that heat-generating disc R01 produces is had suffered insulating process and is only leaned on heating board R02 heating, and the power in view of heating board R02 is very little again; Its power is only kept kettle temperature under the holding temperature state, so cooking bottom temperature can slowly descend.
A3, in insulating process; Cooking bottom temperature can slowly descend; The first temperature controller T1 connects when temperature drops to the lower limit temperature point of the first temperature controller T1; This moment, electric current formed the loop through the switch and the first temperature controller T1 of thermal fuse-link, heater circuit, timer switch TK, and the timing motor of timer switch TK and thermal circuit are owing to being quit work by short circuit simultaneously, and heat-generating disc R01 starts working.
