Advantages of the present invention is：The present invention warning circuit can people forget close cold room refrigerator doors when, with
The form of warning prevents the continuous long-term work of compressor of refrigerator from causing to damage, while avoiding reminding people to shut refrigerator doors
Cause waste of energy.Additionally, due to sound and light alarm is provided simultaneously with, even the old man being hard of hearing can also receive corresponding police
Show signal, so as to shut refrigerator doors in time, therefore, the warning circuit of the present invention is easy to use, and the suitability is wide, is worthy to be popularized.
Description of the drawings
Fig. 1 is that refrigerator of the present invention is forgotten to close the door the circuit diagram of automatic sound-light alarm circuit.
Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, the refrigerator of the present invention forgets automatic sound-light alarm circuit at closing time, which adopts digital circuit CD4060
Module is built as control core；Connect 16 feet, the electricity of CD4060 modules after the positive pole concatenation switch SW of 3V set of cells GB
One end of resistance R1 and R5, the colelctor electrode of audion Q1, the positive pole of electric capacity C2；12 feet of another termination CD4060 module of resistance R1
With one end of photoconductive resistance R2；The base stage and the positive pole of diode D1, D2 of another termination audion Q1 of resistance R5, diode D1
Connect 3 feet and 6 feet of CD4060 modules with the negative pole of D2 respectively, the 8 feet ground connection of CD4060 modules, 9,10,11 feet connect electric capacity respectively
C1, resistance R3, one end of resistance R4, electric capacity C1, resistance R3, the other end of resistance R4 are commonly connected together；Audion Q1's
One end of emitter stage connecting resistance R6 and one end of buzzer BZ, the other end of resistance R6 connect the positive pole of Light-Emitting Diode D3；It is photosensitive
The other end of resistance R2,8 feet of CD4060 modules, the other end of buzzer BZ, the negative pole of Light-Emitting Diode D3, electric capacity C2 it is negative
Extremely connect jointly the negative pole of set of cells GB.
When warning circuit of the present invention is applied on refrigerator, photoconductive resistance R2 should be mounted in beside the light of cold compartment of refrigerator, honeybee
Ring device BZ and Light-Emitting Diode D3 exposes on the outer wall of refrigerator.It is when refrigerator doors are closed, completely black in refrigerator cold-storage room, photosensitive electricity
Resistance R2 is rendered as high impedance status, forces to keep 12 feet of CD4060 modules to maintain high level, and CD4060 modules are in reset state,
Its outfan is low level, and audion Q1 is not turned on, and buzzer BZ and Light-Emitting Diode D3 do not work.When refrigerator doors are opened
When, the indoor lamp of cold compartment of refrigerator is lighted, and makes photoconductive resistance R2 be changed into low impedance state, and 12 feet of CD4060 modules are changed into low electricity
It is flat, reset state is released, agitator is constituted and is started counting up by resistance R3, R4 and electric capacity C1 and CD4060 module, CD4060 modules
6 feet export the signal of about 0.28Hz, Jing after about 30 seconds, 3 feet of CD4060 modules output high level, now buzzer BZ Jing tri-
Pole pipe Q1 sends the audible alarm of closing the door that frequency is 0.28Hz, and continues 30 seconds, if also do not shut after 30 seconds, buzzer BZ stops
Only report to the police 30 seconds, continue afterwards to send audible alarm 30 seconds, such persistent loop is shut until refrigerator doors.Send in buzzer BZ
While audible alarm, Light-Emitting Diode D3 is also lighted as light warning simultaneously as warning lamp.
Above-mentioned legend is only the exemplary embodiments of the present invention, is not limited to the present invention, all spirit in the present invention and
Any modification made within principle or equivalent and improvement etc., should be included within the scope of the present invention.
