Brief description of the drawings
Fig. 1 is the utility model structural principle block diagram.
Embodiment
The utility model is described in further detail with reference to embodiments, but the utility model is not limited to these implementations Example.
A kind of switching system, including timer T1, electrothermal tube D1, triac VS1, diac DB3,2 resistance, 1 slide rheostat R3,2 electric capacity;2 resistance is respectively first resistor R1 and second resistance R2; 2 electric capacity is respectively the first electric capacity C1 and the second electric capacity C2;Described timer one end is connected with the live wire of outside civil power, institute One end of the other end and electrothermal tube of stating timer connects;The other end of the electrothermal tube through the first electric capacity and first resistor with The zero line connection of outside civil power;Zero line of the other end of the electrothermal tube through triac and outside civil power connects Connect;The other end of the electrothermal tube is through slide rheostat, second resistance and diac and triode ac switch Control pole is connected;The other end of the electrothermal tube is connected through slide rheostat, second resistance and the second electric capacity with zero line.
Timer is individual devices, is installed between civil power input and electrothermal tube, during the use of electric kitchen tools, even if Timer is influenceed by the other circuit parts of electric kitchen tools, during maintenance, need to only remove timer so that timer is independently of electricity The remaining circuit system of kitchen tools, can carry out fault detect independent to timer, reduce fault location positioning difficulty.Equally, When the electric other circuit systems of kitchen tools break down, timer can also be removed, troubleshooting directly is carried out to remainder circuit, reduced Troubleshooting scope.
The timer mainly includes clock chip FCP8563.FCP8563 includes I2C EBI functions, FCP8563 Pass through I2C EBIs are connected with controller module, and have extremely low power consumption, suitable for all kinds of electric kitchen tools.
Triac is applied to high voltage, worked under conditions of high current, have high pressure, capacity it is big, The characteristics of small volume.Triac includes T1 poles, T2 poles and control pole G, and no matter is institute's making alive on control pole G For forward direction triggering or negative sense triggering, it may be such that control pole G is turned on.In the utility model, the timing of timer arrives, fire Line is connected with electrothermal tube, and the first electric capacity C1 is started to charge up, and after charging to a certain degree, the voltage of the first electric capacity is by sliding variable resistance Device R3 partial pressures, pass through second resistance R2 current limlitings so that diac DB3 is turned on, and is provided for triac Trigger voltage, the T1 poles of triode ac switch and the conducting of T2 poles, electrothermal tube are started working.Second electric capacity C2 is as energy storage electricity Hold, electric energy is stored during slide rheostat R3 partial pressures, second resistance current limliting, during electrothermal tube normal work, Trigger voltage is imposed by control pole G of the diac to triode ac switch by the second electric capacity C2 so that three ends are double Conducting is maintained during the whole service of switching system to the T1 poles of controllable silicon and T2 poles.Three end provided by the utility model is double To the circuit connecting mode of reverse-blocking tetrode thyristor, high sensitivity.
Further, in addition to fuse F1, the live wire of the outside civil power are connected after fuse with timer. During the use of electric kitchen tools, when occurring overloading or short circuit, circuit system is easily damaged, and therefore, fuse is connected on live wire, Blown fuse, live wire can be disconnected when occurring overloading or being short-circuit.Electric current on zero line is usually less than the electric current in live wire, Therefore generally civil power input live wire between timer installation insurance silk.
