The accompanying drawing explanation
The block scheme that Fig. 1 is the utility model toaster circuit preferred embodiment.
The block scheme that Fig. 2 is other embodiment of the utility model toaster circuit.
Embodiment
The utility model toaster circuit is applicable to various toasters.
With reference to figure 1, Fig. 2 describes the utility model toaster circuit preferred embodiment in detail.
A kind of toaster circuit in the present embodiment, comprise the MCU control circuit, rectification, filtering, mu balanced circuit, the heating wire assembly, electromagnetic switch, control circuit for electromagnet, described electromagnetic switch one end is connected with the L line with the N line, the other end connects described heating wire assembly, described control circuit for electromagnet one end is connected with described electromagnetic switch, the described control circuit for electromagnet other end is connected with described MCU control circuit, described rectification, filtering, one end of mu balanced circuit is connected with described heating wire assembly, the other end is connected with an end of described MCU control circuit and control circuit for electromagnet respectively, it is characterized in that: also comprise automatic power-off circuit, described automatic power-off circuit comprises two or two above relays, described relay is connected on respectively on described N line and L, and be located between described alternating current input and heating wire, one end of described automatic power-off circuit connects the MCU control circuit, described automatic power-off circuit also with described rectification, filtering, mu balanced circuit connects.
In the present embodiment, the utility model toaster circuit also comprises Working state checking circuit, and an end of described Working state checking circuit is connected with the described MCU of stating control circuit, and the other end is connected with described rectification, filtering, mu balanced circuit.
In other embodiments, the utility model toaster circuit also comprises temperature sensing circuit, and described temperature sensing circuit is connected with described MCU control circuit.
In other embodiments, the described automatic power-off circuit of the utility model toaster circuit is provided with switch.
The principle of work of the utility model toaster circuit is:
Alternating current is input to electromagnet, start electromagnetic switch, by relay (relay closes under normal circumstances), to heating wire, heated again, the part tap voltage of heating wire is supplied with the MCU control circuit after rectifying and wave-filtering simultaneously, when normally pressing Working state checking circuit, after the MCU control circuit receives information, carry out the normal heating of various states, after reaching Preset Time, the MCU control circuit is issued control circuit for electromagnet by signal, control circuit for electromagnet disconnects electro-magnet switch, stops heating.But if electro-magnet switch is while being stuck, when MCU exceeds normal working hours detection time, MCU feeds back to automatic power-off circuit by abnormal signal, the relay on automatic power-off circuit hard closing fire zero line, and heating wire is stopped power supply, and plays a protective role.Certainly, automatic power-off circuit also is provided with the hand switch of a relay on hard closing fire zero line.In operation during each function toast bread, if want to exit midway, but the also hand switch of automatic power-off circuit.
Compared with prior art, the utlity model has following beneficial effect: after electromagnetic switch is stuck, when reaching setting-up time, automatic power-off circuit disconnects, and whole circuit quits work, thereby protects the safety of whole toaster circuit.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore doing according to the utility model claim, still belong to the scope that the utility model is contained.
