By being given and by the description of the embodiment of the present utility model shown in accompanying drawing with indefiniteness example below reading, other feature and advantage of the present utility model manifest, in the accompanying drawings with will be apparent from:
-Fig. 1 is electronic unit known in the art, and
-Fig. 2 is according to electronic unit of the present utility model, and
-Fig. 3 shows the bread baker included according to electronic circuit of the present utility model.
Detailed description of the invention
With reference to Fig. 2, Fig. 2 shows according to electronic unit of the present utility model (3), this electronic unit (3) is by electric capacity (C1, C2), resistance (R1, R2, Rz), internal circuit (IC), electric magnet (EM1), at least one audion (Q1), at least one Zener diode (Z) and electronic installation (40) composition.First, these electronic installations (40) are on the one hand for determining that electric magnet (EM1) is kept starting by period persistent period (T1), during first determines the persistent period, electric magnet (EM1) is no longer supplied electric current, and on the other hand for making internal circuit (IC) reset in second determines the persistent period (T2), determine that persistent period, integrated circuit (IC) are no longer supplied electric current from second.
In order to control the toasting performance of bread baker (2), this electronic unit (3) receives by diode (D1) rectification the power supply (AC) that filtered by electric capacity (C1), in order to provide the voltage (U1) of 12Vdc or 24Vdc for the coil (L1) of electric magnet (EM1).
From the beginning of this voltage (U1), and by resistance (Rz), Zener diode (Z1) and electric capacity (C2) are connected in parallel between primary nodal point (10) and secondary nodal point (12), produce the secondary voltage (VDD) of about 5V.This voltage (VDD) is for powering for internal circuit (IC), and internal circuit (IC) is arranged between primary nodal point (10) and secondary nodal point (12) the most in parallel.This internal circuit (IC) guarantees timing and the control of electric magnet (EM1), and this internal circuit can be integrated or be not integrated.
Referring now still to Fig. 2, electronic unit (3) includes the contact node (11) being positioned between electric magnet (EM1) and audion (Q1).
Electronic installation (40) is positioned between primary nodal point (10) and contact node (11).According to this utility model, electronic installation (40) includes at least one audion (Q2) and the resistance (Rb) being installed in series with this audion (Q2).
Implement in modified example at one, it may be considered that remove resistance (Rb) and audion (Q2) is changed to the audion being suitable for bearing base stage peak point current.
Therefore, according to this utility model, this electronic unit (3) allows to obtain and determines the persistent period (T1) more than the first of 300ms and determine the persistent period (T2) less than the second of 1s.
It is also conceivable to connect the stop button (8) of electric magnet (EM1) on electronic unit (3).
With reference to Fig. 3, bread baker (2) includes electronic circuit (1) and the heating element heater (20) powered by the AC voltage source (60) of electrical network, and when bread basket (21) is dropped to lower position by user, heating element heater is powered.The intermediate point (30) being positioned on these heating element heaters (20) is electronic unit (3) power supply.Thus, internal circuit (IC) is also powered and starts electric magnet (EM1) immediately, and bread basket (21) is maintained at lower position by electric magnet.Internal circuit (IC) passes through audion (Q1) at the coil (L1) being controlled electric magnet (EM1) by user by period persistent period (T0) that timer button (T) is selected.In period whole persistent period (T0), bread basket (21) is maintained at lower position, and at the end of this persistent period (T0), circuit (IC) stops toasting performance, and be no longer electric magnet (EM1) power supply, this releases bread basket (21).Stop button (8) allow also to even at the end of the persistent period (T0) is not by force audion (Q1) end and release magnet (EM1).
In mode of operation, with reference to Fig. 2 and Fig. 3, when electronic unit (3) is energized, internal circuit (IC) is powered and controls audion (Q1), starts electric magnet (EM1) and end audion (Q2) when described audion (Q1) reaches saturation.Resistance (R2) is switched off.
In order to obtain the duration of the persistent period (T1) more than 300ms required when power failure, need correct the value of audion (C1) and correct the value of (C2) when needed, electric energy necessary to coil (L1) is on the one hand provided providing, and on the other hand is used for making internal circuit (IC) be maintained at duty.
At the end of timing (T0), the output of internal circuit (IC) changes state with cut-off audion (Q1).Audion (Q2) is therefore saturated by the residual voltage on electric capacity (C1).Audion (Q2) is saturated by coil (L1) and resistance (Rb).Resistance (R2) is then accessed in circuit again, and this causes voltage (VDD) rapid decrease.
The value of resistance (R2) is selected to make voltage (VDD) drop to below the reset threshold of internal circuit (IC) within the desired persistent period (T2), and the persistent period (T2) is less than 1 second.
The electric current that the lower limit of the value of resistance (R2) is chosen to be circulated in this resistance (R2) is less than the electric current circulated in resistance (Rz), thus when energising, when audion (Q1) is not controlled by internal circuit (IC) and when audion (Q2) is saturated, power supply (VDD) is allowed to have enough risings, so that internal circuit (IC) starts.
Implement in modified example at one, it may be considered that remove resistance (Rb), select to be suitable for bearing the audion (Q2) of produced base stage peak point current simultaneously.
Similarly, implement in modified example at another, it may be considered that the voltage in input detection coil (L1) of internal circuit (IC), and one of the output of internal circuit controls audion (Q2).
Finally, in another implements modified example, it is also contemplated that resistance (R2) is positioned to make electric capacity (C1) electric discharge rather than electric capacity (C2) electric discharge.
When electronic device has himself power supply circuits, it is possible to use this solution, as long as the low state of basket makes electronic device also be energized.
This solution is suitable for all types of bread baker (2), regardless of its form.
Certainly, this utility model is not limited to embodiment described and illustrated in the accompanying drawings.In the case of without departing from protection domain of the present utility model, can be modified, especially in terms of the composition of different elements or by technology equivalencing.
