Step S302, utilizes the division module in discharge circuit to carry out dividing potential drop to the power supply of air conditioner, obtains branch pressure voltage.
Step S304: when power supply disconnects, according to the switch module cut-off in branch pressure voltage controlled discharge circuit or conducting.Particularly, if the branch pressure voltage obtained reaches the conducting voltage of switch module, then switch module is in conducting state, if the branch pressure voltage obtained fails to reach the conducting voltage of switch module, then switch module is in cut-off state.
Step S306: when switch module ends, the electric discharge of the discharge module in controlled discharge circuit.Particularly, if switch module be in cut-off state under, the module conducting of switch module controlled discharge is also in the state of repid discharge.
When ending according to branch pressure voltage control switch module, energy-storage module provides energy for switch module, and continue to keep conducting state with control switch module, after Preset Time, control switch module is in off-state.In step S306, when power supply disconnects, the voltage after division module can not reach the conducting voltage of switch module, and the energy stored in energy-storage module can allow switch module continue conducting a period of time.
By the division module being connected to air conditioner power supply two ends, dividing potential drop is carried out to power supply, obtain branch pressure voltage, when air conditioner power supply disconnects, if the value of branch pressure voltage reaches the conducting voltage of switch module, then switch module conducting, if the value of branch pressure voltage does not reach the conducting voltage of switch module, then switch module cut-off, if when switch module is in cut-off, discharge module in controlled discharge circuit enters discharge condition, reach the object of low-power consumption repid discharge, thus achieve the technique effect not adopting special arresting element just can realize low-power consumption repid discharge, and then solve the large technical problem of special electric discharge chip power-consumption of the prior art.
Fig. 4 is the flow chart of the charging method of discharge circuit according to the optional air conditioner of the another kind of the embodiment of the present invention.As shown in Figure 4, the method comprises the steps that S402 is to step S406:
Step S402: when power supply conducting, when the voltage rise of power supply is to first object voltage, discharge module conducting.
Step S404: when voltage rise to the second target voltage of power supply, branch pressure voltage control switch module is in conducting state, is in off-state with controlled discharge module.
Step S406: when power supply is connected, if the reversing of power supply, the energy-storage module in discharge circuit provides energy for switch module, maintains conducting state with control switch module.
Particularly, the process that whole discharge circuit mainly experiences that power supply is connected, start, standby and power supply cut off.The power supply of air conditioner is alternating current, when power supply conducting, if the voltage rise of power supply is to first object voltage, wherein, first object voltage can meet discharge module conducting, but now discharge module does not discharge, because the electric capacity in the second triode inside does not have stored energy.When voltage rise to the second target voltage, the branch pressure voltage that the second target voltage obtains after division module dividing potential drop meets switch module conducting, if switch module conducting, then controlled discharge module can be in off-state.When power supply is operated in negative semiaxis, that is the polarity of power supply there occurs change, and now discharge circuit is not in running order, and so utilize energy-storage module to provide energy for switch module, maintained switch module keeps conducting state.
