[accompanying drawing explanation]
Fig. 1 is the utility model structural representation;
Fig. 2 is the electrical block diagram of prior art;
Fig. 3 is structural representation of the present utility model.
[embodiment]
Be described in further detail below in conjunction with accompanying drawing and embodiment of the present utility model:
As shown in figures 1 and 3, a kind of circuit that calandria constantly heats when preventing controller from makeing mistakes, include controller 1, described controller 1 is connected with switching power circuit 2 and control relay circuit 3, described control relay circuit 3 is connected with heater 4, described heater 4 is electrically connected with city, described control relay circuit 3 is connected with switching power circuit 2, described control relay circuit 3 includes triode Q1 and relay R LY1, described relay R LY1 mono-coil input end is connected with triode Q1 collector, another coil input end of described relay R LY1 is connected with switching power circuit 2, described relay R LY1 gauge tap one end is connected with heater 4, the described relay R LY1 gauge tap other end is connected with live wire, described triode Q1 grounded emitter, described triode Q1 base stage respectively with resistance R4, resistance R5 one end connects, resistance R5 other end ground connection, the resistance R4 other end respectively with diode D8 negative pole end, electrochemical capacitor E4 positive terminal connects, electrochemical capacitor E4 negative pole end ground connection, diode D8 positive terminal respectively with electric capacity C4 one end, diode D9 negative pole end connects, diode D9 positive terminal ground connection, the electric capacity C4 other end is connected with controller 1.
Wherein, described heater 4 is heat-generating pipe, heat-generating disc or heating box, and this circuit can be applicable in the heating electrical appliances such as electric heater, electric furnace, baking box.
As shown in Figure 2, when existing heater circuit needs to carry out heating work, controller 1 sends high level signal to control relay circuit 3, and the gauge tap in control relay circuit 3 closes, and heater 4 electricly must carry out heating work, therefore, make mistakes when controller 1 sends high level signal to control relay circuit 3, namely send high level signal to control relay circuit 3 always, heater 4 is constantly generated heat, make temperature constantly increase, cause danger.
As shown in Figure 3, when the utility model circuit needs to carry out heating work, controller 1 sends the square-wave signal of certain frequency to control relay circuit 3, the electric capacity C4 in control relay circuit 3 is made to form path, relay R LY1 could be allowed to work, thus make heater 4 carry out heating work, therefore, even if there is mistake when exporting high level in controller 1, namely continue to send high level to control relay circuit 3, relay R LY1 can not be made to work, and namely heater 4 can not carry out continuous heating work always, decreases the danger using heating electrical appliance.
