Description
Technical field
The utility model relates to a kind of toaster.
Background technology
Toaster and toaster are a kind of conventional kitchen articles, are mainly used to toast rusk.When toaster is in running order, ambient temperature residing for its circuit is quite high, and usually electronic component working temperature is general all between 85-105 degree at present, the impact that can cause circuit when temperature anomaly raises, even can cause and catch fire when overheated.And in the normal situation of ambient temperature, if supply voltage raises suddenly or cause tap voltage abnormal higher because tap heating wire part disconnects, the control circuit connected below can be subject to very serious destruction.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to the anti-overheated anti-pressure type toaster excessively providing a kind of auto-breaking under high temperature or high-pressure situations.
For achieving the above object, the utility model adopts following technical scheme: a kind of anti-overheated anti-pressure type toaster excessively, comprise switch S 1, switch S 2, heating wire H1, heating wire H2, heating wire H3, heating wire H4, current insurance silk FS1, diode D1, electromagnet M1 and control circuit module, also comprise Thermal Cutoffs FT1 and piezo-resistance Rv1; One end of one end of wherein said Thermal Cutoffs FT1 and switch S 1, heating wire H2, heating wire H1, heating wire H3, heating wire H4 and switch S 2 is cascaded in order, the other end of described Thermal Cutoffs FT1 is connected with the live wire ACL of external power source, and the other end of described switch S 2 is connected with the zero line ACN of external power source; Described heating wire H4 is provided with tap, one end of described current insurance silk FS1 is connected with this tap, the other end of described current insurance silk FS1 is not only connected with the positive pole of diode D1, is also connected with one end of switch S 2 by piezo-resistance Rv1, one end ground connection of described switch S 2; The input port of the described control circuit of described diode D1 is connected, and the negative pole of described diode D1 is connected with the control of Electric potentials port of described control circuit by described electromagnet M1, and wherein said electromagnet M1 is used for the folding of control switch S1 and switch S 2; Described control circuit is also provided with a grounding ports.When ambient temperature rises to the fusing value of Thermal Cutoffs FT1, Thermal Cutoffs FT1 automatically disconnects thus cuts off the electricity supply; The meeting when the voltage overrate at piezo-resistance Rv1 two ends and cause current surge, then current insurance silk FS1 quick fuse thus cut off the electricity supply.
Further, described switch S 1 is 2-in-1 and be a double-pole single throw with described switch S.Double-pole single throw can realize switch S 1 and open function with the same pass of switch S 2 is same.
Further, the negative pole of described diode D1 is by electric capacity C1 ground connection.
Further, described electromagnet M1 is parallel with a diode D2, and the positive pole of described diode D2 is connected with the control of Electric potentials port of described control circuit.
The beneficial effects of the utility model are as follows: the function that can realize auto-breaking when high temperature or high pressure, thus each several part circuit element in protective circuit.
Accompanying drawing explanation
Fig. 1 is that the utility model prevents the overheated anti-circuit diagram crossing the better embodiment of pressure type toaster.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further:
Refer to Fig. 1, the utility model relates to a kind of anti-overheated anti-pressure type toaster excessively, its better embodiment comprises switch S 1, switch S 2, heating wire H1, heating wire H2, heating wire H3, heating wire H4, current insurance silk FS1, diode D1, electromagnet M1 and control circuit module, also comprises Thermal Cutoffs FT1 and piezo-resistance Rv1; Wherein one end of Thermal Cutoffs FT1 and one end of switch S 1, heating wire H2, heating wire H1, heating wire H3, heating wire H4 and switch S 2 are cascaded in order, the other end of Thermal Cutoffs FT1 is connected with the live wire ACL of external power source, and the other end of switch S 2 is connected with the zero line ACN of external power source; Heating wire H4 is provided with tap, and one end of current insurance silk FS1 is connected with this tap, and the other end of current insurance silk FS1 is not only connected with the positive pole of diode D1, is also connected with one end of switch S 2 by piezo-resistance Rv1, wherein one end ground connection of switch S 2; The negative pole of diode D1 is DC power output end VDD, DC power output end VDD is connected with the input port one of control circuit, DC power output end VDD is also connected with the control of Electric potentials port 3 of control circuit by electromagnet M1, DC power output end VDD is also by electric capacity C1 ground connection, wherein electromagnet M1 is used for the folding of control switch S1, switch S 2, electromagnet M1 is also parallel with a diode D2, and the positive pole of diode D2 is connected with 3 mouthfuls, the control of Electric potentials end of control circuit; Control circuit is also provided with a grounding ports 2.
Wherein switch S 1 and switch S 2 can merge into a double-pole single throw.Tap place of heating wire H4 and the voltage of earth terminal are tap voltage, its tap voltage can be set to 24Vac or 48Vac etc. according to actual conditions, electric current flows through current insurance silk FS1 and change direct current into after diode D1 and electric capacity C1 rectification, and this direct current is that control circuit is below powered.
The operation principle of the utility model circuit is as follows: external power source is civil power 220V ~ 240V, when toaster work time, raise if the ambient temperature residing for circuit is abnormal, the Thermal Cutoffs FT1 at the live wire ACL access port place of external power source can disconnect automatically when temperature rises to its fusing value, follow-up heating wire no longer continues heating, and because electromagnet M1 loses suction after power-off, it no longer includes control action to switch S1 and switch S 2, therefore switch S 1 and switch S 2 disconnect.
When external voltage supply voltage raises suddenly or tap heating wire part disconnects and causes piezo-resistance Rv1 both end voltage overrate; the electric current of circuit sharply increases; and quick disconnection can be realized in the process that sharply increases at electric current of current insurance silk FS1, the circuit of rear class can be protected in time.When late-class circuit power down, electromagnet M1 loses suction, and it no longer includes control action to switch S1 and switch S 2, therefore switch S 1 and switch S 2 disconnect, then heating wire can not relay generate heat, thus well serves protective effect.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection range of the utility model claim.
