Occupy field.
Background technology
With the continuous improvement of people's living standard, refrigerator has become the essential household electrical appliance of daily life
One of.People utilize refrigerator storage food, the medicine that must be preserved at low temperature etc., in order to ensure that these articles never degenerate,
The a few days in the case of nobody, does not turn off refrigerator power supply yet, is at normal operating conditions, still, in the event of family in family
In nobody when power-off a period of time, the situation about restoring electricity again before owner goes home, power-off makes a certain in refrigerator this period
Food or medicine go bad, and after owner returns, can not judge the electricity that whether broke in family, and do not see from food or drug substance surface
Through rotten, it is likely that the event that can cause to eat rotten food or medicine by mistake occurs, and influences the health of people.Therefore, existing ice
Increase is needed to monitor the function whether refrigerator occurred power-off in case, the people to be gone back home after a few days that enables to go out intuitively sees
Go out at home in nobody this period, whether refrigerator occurred the situation of power-off, so as to which whether the article judged in refrigerator can
It can not eat.
The content of the invention
The purpose of the present invention is to solve current refrigerator can not to judge whether that powering-off state occurred, so as to judge ice
The problem of whether case article can also eat.
The present invention adopts the technical scheme that to solve the above problems：A kind of intelligence with power failure memory function of the present invention
Energy refrigerator, its circuit structure include：
Power supply, temperature controller, overload protecting circuit, starting relay and compressor electric motor, the compressor electric motor and power supply
Between connect display unit, power-off monitoring unit, stand-by power supply and data storage list are sequentially ingressed between the power positive cathode
Member, the data storage cell are used to store power cut-off information, and the data storage cell is also connected with display unit, and display unit is used
In display power cut-off information.
Further, the power-off monitoring unit circuit includes：Step-down rectifier bridge circuit, drive circuit and monitoring relay
Device, step-down rectifier bridge circuit are used to the 220V voltage commutations of refrigerator power supply being depressured, and to drive circuitry, drive circuit is used for
Control the "on" position of control relay.
Yet further, the drive circuit is transistor driver circuit or driver circuits for integrated circuit.
Further, the stand-by power supply is battery.
Further, the display unit includes being arranged on the LCDs outside refrigerator.
Further, the power cut-off information includes power-off time point, power-off duration and power-off number.
Beneficial effect：
The present invention sets control relay to survey powering-off state in circuit, and is stored and powered off by data storage cell
Data, and the data message powered off every time is shown by display unit, allow users to get information about in getting home nobody when
In, the powering-off state of refrigerator, so as to judge whether the article in refrigerator is also suitable for using, avoid not judge refrigerator from outward appearance
Whether interior article goes bad, and can not know the powering-off state of refrigerator again, eats the food or medicine to have gone bad by mistake, endangers health
Situation.
