Abstract
The invention discloses a kind of refrigerator doors not to fasten warning system, 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, 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 closes by photo resistance, with confirm user be in closing the door in the state that takes food but the state do not fastened, if it is light yellow to detect refrigerator lighting lamp, illustrate that user takes food, any operation is not done then；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 fasten door, and now MCU driving buzzer is alarmed.The inventive structure is simple, has good using effect.
Description
Technical field
The present invention relates to household appliance technical field, more particularly to a kind of refrigerator doors do not fasten warning system.
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 does not fasten warning system, to solve the old men do not fasten refrigerator but fail and
Shi Faxian, causes refrigerator long-term work, easily causes failure and to cause temperature not reach requirement easy because refrigerator is not fastened
Cause food spoilage, eat the food to addle and the problem of uncomfortable or even food poisoning easily occur.
To solve the above problems, the present invention adopts the following technical scheme that realization：
A kind of refrigerator doors do not fasten warning system, including control unit, power subsystem, door detection unit, optical detecting 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 alarm unit is connected with the interface of control unit the 3rd.
Preferably, the single-chip microcomputer uses AVR series monolithics.
Preferably, the rechargeable battery is button rechargeable battery.
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 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 buzzer is alarmed.The inventive structure is simple, convenient use, has and uses well
Effect.
