Below in conjunction with principle of work, above-mentioned power-supplying circuit is described further:
When dish-washing machine is in off-position, and user need start dish-washing machine perform washing procedure time, user presses Self-resetting double-point double-throw switch SW, now first normally opened contact 1 of Self-resetting double-point double-throw switch SW is communicated with the first switch contact 2, second normally opened contact 3 is communicated with second switch contact 4, so, the first input end L of AC/DC changeover switch 101 is communicated with civil power live wire, and export+12V direct current and first common pin 1 of+5V direct current to relay R EL and the first end of resistance R1 respectively from its first output terminal V1 and the second output terminal V2, then master controller 103 starts work because its power end VCC obtains power supply, and export high level (i.e. conducting control level) driving N PN type triode Q1 conducting from its level output end OUT, and then the normally opened contact 3 continuing guard relay REL when user unclamps Self-resetting double-point double-throw switch SW is communicated with switch contact 4, thus make AC/DC changeover switch 102 continue to export+12V direct current and+5V direct current, then master controller 103 controls dish-washing machine and enters washing procedure after user unclamps Self-resetting double-point double-throw switch SW.
Run in washing procedure process at dish-washing machine, if when user manually presses Self-resetting double-point double-throw switch SW to realize manual power-off, whether master controller 103 is in running status by potential change (namely from high level saltus step be low level) the judgement electric loading 200 detecting its voltage detecting end IN, be, then first closedown electric loading, and NPN type triode Q1 shutoff is controlled from its level output end OUT output low level (namely turning off control level) after time delay one specified time interval (as 1 second), so, relay R EL disconnects along with the shutoff of NPN type triode Q1.In order to ensure that relay R EL normally disconnects, master controller 103 is in output low level and time delay one specified time interval (as 5 seconds) judges whether the current potential of its voltage detecting end IN is zero (namely judging whether switch reference level is zero) afterwards, if, then show that relay R EL normally disconnects, whole dish-washing machine enters Zero-power-consumption standby state; If not, then control voice guard 301 and to sound warning, and control display 302 and show power-off miscue information.When the time of sound warning and display power-off miscue information arrives a specified time interval (as 30 seconds), master controller 103 can control voice guard 301 and stop sounding warning, and retain control display 302 continue display power-off miscue information until user by operation Self-resetting double-point double-throw switch SW again manual power-off to get rid of power-off abnormal conditions, and make dish-washing machine enter normal Zero-power-consumption standby state.Wherein, if user operates Self-resetting double-point double-throw switch SW during voice guard 301 sounds warning carry out manual power-off, then voice guard 301 can stop warning of sounding, and display 302 also stops display power-off miscue information, whole dish-washing machine enters normal Zero-power-consumption standby state.
After the washing procedure run at dish-washing machine terminates, master controller 103 can control NPN type triode Q1 from its level output end OUT output low level (namely turning off control level) and turn off after time delay one specified time interval (as 5 seconds), so relay R EL disconnects along with the shutoff of NPN type triode Q1.In order to ensure that relay R EL normally disconnects, master controller 103 is in output low level and time delay one specified time interval (as 5 seconds) judges whether the current potential of its voltage detecting end IN is zero afterwards, if so, then show that relay R EL normally disconnects, whole dish-washing machine enters Zero-power-consumption standby state; If not, then control voice guard 301 to sound warning, and control display 302 and show power-off miscue information, when the time of sound warning and display power-off miscue information arrives a specified time interval (as 30 seconds), master controller 103 can control voice guard 301 and stop sounding warning, and retain control display 302 continue display power-off miscue information until user by operation Self-resetting double-point double-throw switch SW again manual power-off to get rid of power-off abnormal conditions, and make dish-washing machine enter normal Zero-power-consumption standby state.Wherein, if user operates Self-resetting double-point double-throw switch SW during voice guard 301 sounds warning carry out manual power-off, then voice guard 301 can stop warning of sounding, and display 302 also stops display power-off miscue information, whole dish-washing machine enters normal Zero-power-consumption standby state.
It is worth mentioning that, when warning device is the light fixture that can flash, once relay R EL cannot normally disconnect, then master controller 103 can control this light fixture that can flash and to flash alarm according to certain flicker frequency.
