Embodiment
Embodiment:
Schematic diagram of the present utility model and circuit diagram are respectively as Fig. 1, shown in 2, the automatic control equipment of the utility model microwave oven, include first sensitive switch 1, second sensitive switch 2, have electricity and isolate and transmit the coupling electronic device 3 of signal, relay 4, microwave oven main control chip 5, the electronic device 3 that wherein is coupled is connected with power supply by first sensitive switch 1 and second sensitive switch 2 of connecting with it, the signal output part of coupling electronic device 3 is connected with the signal input part of microwave oven main control chip 5, the contacting of microwave oven main control chip 5 control relays 4 and the signal output part of disconnection are connected with relay 4, and relay 4 is connected with power supply.In the present embodiment, microwave oven main control chip 5 is a single-chip microprocessor MCU, and coupling electronic device 3 is an optocoupler.
In the present embodiment, above-mentioned coupling electronic device 3, relay 4 and microwave oven main control chip 5 are installed on the computer control board 6, computer control board 6 also is equiped with supply socket 7, coupling electronic device 3 is connected in series by supply socket 7 and first sensitive switch 1 and second sensitive switch 2, and relay 4 is connected with power supply by supply socket 7.
In the present embodiment, above-mentioned power supply is a communication power supply.Above-mentioned first sensitive switch 1, second sensitive switch 2 are interlocking switch, and first sensitive switch 1 is a normally closed switch, and second sensitive switch 2 is a normal open switch.
Operation principle of the present utility model is as follows: when microwave oven opens the door, first sensitive switch 1 disconnects, second sensitive switch, 2 closures, supply socket 7 energized, electronic device 3 be coupled this moment because the disconnection of sensitive switch 1 can not energized, and coupling electronic device 3 output high level are represented door opening state to microwave oven main control chip 5, microwave oven main control chip 5 thinks that be door opening state this moment, and relay 4 is with the power supply self-locking.
After the microwave oven user puts cooking food microwave oven into and closes upper furnace door, second sensitive switch 2 disconnects, first sensitive switch, 1 closure, supply socket 7 is by relay 4 power supplies of closure, this moment, the user can carry out cooking work by operating computer control board 6 startup microwave ovens, behind the end of cooking, after the user takes out food and shuts door of microwave oven, behind the microwave oven main control chip 5 automatic time delay certain hours, control relay 4 disconnects the power supply of microwave oven supply power socket 7 automatically, thereby realizes the automatic outage of whole microwave oven computer control board 6.After the power supply automatic disconnection of microwave oven computer control board 6, although attaching plug is not taken off or do not had the powered-down switch, microwave oven shutdown this moment power consumption is zero.
