Abstract
The invention discloses a kind of refrigerator doors to fasten system automatically,It is related to household appliance technical field,Refrigerator is not fastened for the old men but to fail to find in time,Cause refrigerator long-term work,Easily cause failure and because refrigerator is not fastened and causes temperature not reach requirement easily to cause food spoilage,Eat the food to addle and the problem of uncomfortable or even food poisoning easily occur,Use using single-chip microcomputer as core,Refrigerator doors are detected by using travel switch and judges whether to fasten and detects whether refrigerator lighting lamp is closed to judge whether in the state for not fastening door by photo resistance,If do not fasten,MCU driving electromagnet produces electromagnetic attraction and refrigerator doors is attracted and fastened,If detecting that travel switch is also not detected by after electromagnetic attraction attracts fastens signal,Then alarmed by MCU driving buzzer to remind user to fasten manually.The inventive structure is simple, convenient use, has good using effect.
Description
Technical field
The present invention relates to household appliance technical field, more particularly to a kind of refrigerator doors fasten system automatically.
Background technology
As China human mortality aging, old solitary people are more and more.Because the old men react slack-off, often occur opening ice
Refrigerator doors, which are not fastened, after case feeding product does not also realize, frequently results in refrigerator and is worked long hours because insulation is bad, easily causes event
Barrier；Not reaching the temperature of refrigeration due to the temperature in refrigerator easily causes food spoilage, then eats the food to addle and easily cause body
Body is uncomfortable even to poison by food.
The content of the invention
The present invention provides a kind of refrigerator doors and fastens system automatically, and not fastening refrigerator solving the old men but fails in time
It was found that cause refrigerator long-term work, easily cause failure and because refrigerator is not fastened and causes temperature not reach requirement easily to lead
Food spoilage is caused, the food to addle is eaten and the problem of uncomfortable or even food poisoning easily occurs.
To solve the above problems, the present invention adopts the following technical scheme that realization：
A kind of refrigerator doors fasten system automatically, it is characterised in that including control unit, power subsystem, door detection unit, light detection
Unit, execution unit, alarm unit；
Described control unit includes single-chip microcomputer, for coordinating, controlling the work of whole system；
The power subsystem includes rechargeable battery, for providing the energy, the power subsystem and control unit power supply for system
End connection；
The door detection unit is connected with control unit first interface；
The optical detecting unit is connected with control unit second interface；
The execution unit is connected with the interface of control unit the 3rd；
The alarm unit is connected with the interface of control unit the 4th.
Preferably, the single-chip microcomputer uses AVR series monolithics.
Preferably, the rechargeable battery is the rechargeable battery that capacity is no less than 2000mAh.
Preferably, the door detection unit includes travel switch, is arranged close to the position of refrigerator doors, is for refrigerator doors
No closing is in place.
Preferably, the optical detecting unit includes photo resistance, for detecting whether refrigerator lighting lamp closes.
Preferably, the execution unit includes electromagnet, for the refrigerator doors do not fastened to be attracted so as to close using magnetic force
Tightly.
Preferably, the alarm unit includes buzzer, for sending sound prompting user.
The present invention using single-chip microcomputer as core, refrigerator doors are detected by using travel switch and judge whether to fasten and
Detect whether refrigerator lighting lamp closes by photo resistance, to confirm that user is to be in closing the door still in the state that takes food
The state do not fastened, if detecting that refrigerator lighting lamp is light yellow, illustrate that user takes food, then do not do any operation；
If detecting that refrigerator lighting lamp is closed, but travel switch does not detect the signal of door-closing in-place, then explanation is that user does not have
Door is fastened, now MCU driving electromagnet produces electromagnetic attraction and refrigerator doors are attracted and fastened, if by electromagnetic attraction
Detect that travel switch is also not detected by after attraction and fasten signal, then alarmed by MCU driving buzzer to remind user
Fasten manually.The inventive structure is simple, convenient use, has good using effect.
