Advantages of the present invention is：The cold compartment of refrigerator of the present invention close the door alert circuit can people forget close refrigerating chamber
Refrigerator doors when, with acousto-optic remind in the form of to remind people to shut refrigerator doors, prevent the continuous long-term work of compressor of refrigerator
Cause to damage, avoid causing waste of energy simultaneously.Additionally, due to being provided simultaneously with acousto-optic prompting function, even be hard of hearing is old
People also can receive corresponding light prompting signal, so as to shut the refrigerator doors of refrigerating chamber in time, therefore, the refrigerator of the present invention
Refrigerating chamber is closed the door, and alert circuit is easy to use, and applicability is wide, is worthy to be popularized.
Brief description
Fig. 1 is that the cold compartment of refrigerator of the present invention is closed the door the circuit diagram of alert circuit.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
The alert circuit as shown in figure 1, cold compartment of refrigerator of the present invention is closed the door, its adopt digital circuit CD4060 module and
Y976 integrated alarm circuit is built as core；The minus earth of 6V battery pack GB, connects after positive pole concatenation switch SW
16 pin of CD4060 module, one end of resistance R1 and R5, the colelctor electrode of triode Q1, the positive pole of electric capacity C2, the negative pole of electric capacity C2
Ground connection；12 pin of another termination CD4060 module of resistance R1 and one end of photo resistance R2, another termination of photo resistance R2
Ground；The base stage of another termination triode Q1 of resistance R5 and the positive pole of diode D1, D2, the negative pole of diode D1 and D2 connects respectively
3 pin of CD4060 module and 6 pin, 8 pin ground connection of CD4060 module, 9,10,11 pin meet electric capacity C1, resistance R3, resistance R4 respectively
