Further, control panel has fast shelves and the slow shelves of stewing stewed, and the fast gauge tap closure that heats while stewing shelves heats that gauge tap cuts out and preservation and controlling switch closure while stewing shelves slowly.
The utility model has the advantage of:
1, only need a heat generating member can realize the fast stewed and slow stewed switching of insulation of heating, reduce manufacturing cost.
2, burner on light only lights in the time of heat generating member total power, and insulation indicator lamp lights under whole keeping warm mode, and the instruction of heated condition and keeping warm mode is clear and definite.
Brief description of the drawings
Fig. 1 is circuit diagram of the present utility model.
Detailed description of the invention
Embodiment 1
As shown in Figure 1, a kind of thermal circuit, comprise heat generating member 1, burner on light L1 and insulation indicator lamp L2, insulation indicator lamp L2 connects with the first resistance R 1, the first diode D1 and forms insulation instruction branch road, and burner on light L1 connects with the second resistance R 2, the second diode D2 and forms heating instruction branch road; Preservation and controlling K switch 1 is connected with the 3rd diode D3 and is formed preservation and controlling branch road; Insulation instruction branch road, preservation and controlling branch road and heating gauge tap 3 first unit in parallel that forms in parallel, heating instruction branch road formation second in parallel with heat generating member 1 unit in parallel; The first unit in parallel and the second units in series in parallel, in the same way, the first diode D1 and the 3rd diode D3 are reverse for the first diode D1 and the second diode D2; When electric current is flowed through insulation instruction branch road and the second unit in parallel, burner on light L1 is and extinguishes state.The resistance of the first resistance R 1 of insulation instruction branch road is much larger than the resistance of the second unit in parallel, makes the undertension that loads on the second unit in parallel so that the second diode D2 conducting, and burner on light L1 is in extinguishing state.
When 3 conducting of heating gauge tap, heat generating member 1 is in full power operation state, and now burner on light L1 is bright, and insulation indicator lamp L2 goes out.The keeping warm mode of heat generating member 1 in half-power work when heating gauge tap 3 disconnects, when electric current positive half-wave, the 3rd diode D3 cut-off, electric current is flowed through and is incubated instruction branch road and the second unit in parallel, due to the dividing potential drop effect of the first resistance R 1, the second diode D2 and burner on light L1 cannot conductings, and burner on light L1 goes out, and is only incubated indicator lamp L2 bright; When the negative half-wave of electric current, the first diode D1 and the second diode D2 cut-off, the 3rd diode D3 conducting, preservation and controlling K switch 1 closure, electric current flow through preservation and controlling branch road and heat-generating disc, insulation indicator lamp L2 waits for the arrival of positive half-wave under twilight sunset.
Heating gauge tap 3 is timer.Electric cooking pot and electrical boiler all need to control by the heat time, and cooking time is longer, can not control and enter insulation with temperature spot.Therefore, the utility model adopts timer as heating gauge tap 3, by regulating timer, realizes free cooking time. in the time that timer time makes zero, automatically enter keeping warm mode.
Burner on light L1 and insulation indicator lamp L2 are light emitting diode.Burner on light L1 and insulation indicator lamp L2 and the first diode D1 are in the same way.
Connecting with fuse-link 2, anti-dry heating temperature controller K2 in the first unit in parallel and the second unit in parallel, causes circuit to damage when preventing current anomaly and the dry combustion method of interior pot.
The utility model has the advantage of:
