Description
Technical field
The present invention relates to refrigerator air door detection control field.
Background technology
On market, wind cooling refrigerator often occurs the situation that air door cannot be opened because freezing, and causes refrigerator compartment normally cannot make
Cold.Such case is directed to, and all heater strip defrost is increased in air door in a lot of refrigerators at present, as shown in figure 1, heater strip is adopted
Duration control method, as shown in Fig. 2 discontinuous is heated according to certain time length, frost chemical conversion eaves gutter is walked, prevents the icing from blocking wind
Door.
But a lot of defects are yet suffered from by above-mentioned means：
1st, air door is in horizontal positioned, and the defrosting water of heating is difficult to drain (can discharge after aggregation is a certain amount of) in time,
Although the effect of defrost is served, can freeze again quickly, ultimately result in air door and be frozen in；
2nd, when compartment humidity is king-sized or when food is more, frosting velocity is very fast near the air door, and air door
The heating of heater strip discontinuous needs the regular hour, if frosting velocity exceedes the speed of defrost, the ice sheet of generation constantly can tire out
Product, causes air door stuck；
3rd, defrost can not be carried out according to ice condition, if defrost cannot also determine completely, causes under many operating modes, wind
Door still effectively can not be opened.
Content of the invention
The present invention cannot be opened due to freezing to solve refrigerator air door, while existing solution also thoroughly cannot be solved
Problem certainly, provides a kind of refrigerator air door icing detection control method, system, device and refrigerator.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：A kind of refrigerator air door freezes and detects control method, should
Method is comprised the following steps：
Whether S1, detection air door ask to open；
S2, when air door request open when, detect damper motor current value, according to current value change within a certain period of time
Situation judges whether air door needs heating.
The invention has the beneficial effects as follows：By when air door request is opened, to air door current of electric within a certain period of time
Change judges whether air door can be normally-open, and then can learn whether air door has frozen, it is possible thereby to targetedly
Constantly heating is carried out until air door can be opened to air door fan door surrounding.How many, no matter in the case of air door fan door ice, all may be used
With effectively solving in door opening, detect whether to freeze and effectively remove ice formation issues, it is ensured that air door is successfully opened.
On the basis of technique scheme, the present invention can also do following improvement.
Further, the process that the S2 is implemented includes：
S21, when air door request open when start air door, and detect situation of change of the damper motor electric current within the t1 time with
Judge whether air door needs heating；
S22, when heating to air door, open main air intake every the t2 time and the electric current of damper motor examined
Survey, t2 >=t1, until the electric current of damper motor stops after no increasing heating air door in the t1 time after door opening.
Using the beneficial effect of above-mentioned further scheme it is：By detecting whether air door electric current in opening process becomes
Change, judge whether air door has frozen by the situation of change of electric current, when air door freezes, which is heated, and repeatedly to electricity
Stream carries out detection until door opening, can be under various icing condition in air door, it is ensured that air door can be normally-open.
Further, the detailed process of the S21 includes：
S211, start when air door request is opened and the timing of t1 program start air door；
Whether S212, detection damper motor electric current increased within the t1 time, if it is, it is judged as that air door needs heating,
If it is not, then being judged as that air door, without the need for heating, simultaneously closes off the timing of t1 program and stops the current detecting to damper motor.
Using the beneficial effect of above-mentioned further scheme it is：When air door cannot be opened, damper motor continuous firing causes
By detecting current of electric, the situation that current of electric increases suddenly, for a kind of this situation, can judge whether air door freezes,
More directly perceived effective.
Further, the detailed process of the S22 includes：
S221, air door is heated, close the timing of t1 program and simultaneously control air door fan door that original closed position is returned to, while
Start t2 program timing；
S222, main air intake is opened every the t2 time and the electric current of damper motor is detected, until after door opening
The t1 time in the electric current of damper motor no increase, close the timing of t2 program and simultaneously stop heating air door.
Using the beneficial effect of above-mentioned further scheme it is：In the situation that first time detection air door electric current increases, to wind
Door is heated to change ice, is only to judge thickness that air door freezes by one-time detection, while being continued for wind
Door carries out heating and irrational, accordingly, it would be desirable to whether can be normally-open to judge air door by multiple current detecting,
Now then it is believed that the ice around air door has melted.Change ice process more fully, thoroughly.
Further, the t1 time is the air door normally-open time.
Using the beneficial effect of above-mentioned further scheme it is：Change by current of electric in the time normally-open to air door
Change situation can preferably reflect state of the air door in opening process as foundation, more intuitively, effectively.
