Abstract
The invention relates to the technical field of refrigerators in household appliances, in particular to a method for controlling the defrosting of a direct cooling refrigerator. The method comprises the following steps of: sensing the temperature of an evaporator temperature sensor after the refrigerator is electrified; if the temperature of the sensor is higher than T DEG C, judging that the refrigerator is electrified for the first time, timing and defrosting t1 hours after the refrigerator is electrified; if the temperature of the sensor is lower than T DEG C, judging that the refrigerator is electrified once again, timing and defrosting t2 hours after the refrigerator is electrified; and after defrosting is finished, starting timing immediately and selecting a defrosting moment at the interval of t3 hours. In the method, self-adaptive defrosting is performed by judging whether a user uses the refrigerator normally at a control point that the refrigerator door o is not opened nor closed in 4 hours in a period of 24 hours.
Description
Technical field
The present invention relates to the technical field of refrigerator in the household electrical appliance, especially relate to a kind of control method of defrosting of direct cooling refrigerator.
Background technology
The regular defrosting control method that uses in the market is normally judged according to the Cumulative Elapsed Time of compressor.This method is not considered user's use experience, if in the user normally uses the process of refrigerator, defrost occurs, can influence the use experience of user to product greatly.
Summary of the invention
The technical problem that the present invention will solve is to improve the shortcoming of technology now, and a kind of defrosting of direct cooling refrigerator control method is provided, and this method can the intelligent decision user be used product specification, thereby under the improper behaviour in service of refrigerator, carries out defrost.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of control method of defrosting of direct cooling refrigerator is characterized in that:
After the refrigerator plug-in, sensing evaporator TEMP actuator temperature at first;
If its temperature is higher than T ℃, judge that then refrigerator is first energising, clock, in refrigerator plug-in defrost after t1 hour; If its temperature is lower than T ℃, judge that then refrigerator for switching on once more, clocks, in refrigerator plug-in defrost after t2 hour;
After defrost finishes, begin immediately to clock, and be to carry out in the cycle with t3 hour.
The control method of above-mentioned defrosting of direct cooling refrigerator is characterized in that: said T ℃ is 5 ℃.
The control method of above-mentioned defrosting of direct cooling refrigerator is characterized in that: said t1 is 10 hours.
The control method of above-mentioned defrosting of direct cooling refrigerator is characterized in that: said t2 is 4 hours.
The control method of above-mentioned defrosting of direct cooling refrigerator is characterized in that: said t3 is 24 hours.
The control method of above-mentioned defrosting of direct cooling refrigerator is characterized in that:
The refrigerator defrost was an one-period with 24 hours, and once and only defrost is once in defrost in 24 hours; The concrete grammar of defrost is:
In 24 hours cycle, the switch of monitoring refrigerator doors;
If cross the situation that 4 hours refrigerator doors are not opened, then after shutdown, begin defrost process, no longer defrost remaining time in the cycle;
If the situation that continuous 4 hours refrigerator doors are not opened do not occur, then after 24 hours periods finish, get into defrost.
The control method of above-mentioned defrosting of direct cooling refrigerator is characterized in that:
Whether the time of having a rest of selected normal adult is 6 to 8 hours every days, and the defrost time is no more than one and a half hours, so select 4 hours as the defrost strategic point, having a rest or durante absentia in order to judges, thereby guaranteeing defrost during the user does not use refrigerator.
The present invention with respect to the beneficial effect of prior art is:
1) once defrost in the cycle has guaranteed the refrigeration of refrigerator;
2) be criterion with 4 hours, can be from motion tracking user use habit, judge and do not use the user under the situation of refrigerator and carry out defrost;
3) after user's use habit changed, this program also can be done self adaptation and regulate, and the selection on defrost opportunity can be regulated according to user's use habit automatically, has certain intelligent effect.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation.
Fig. 1 is the defrost control that the present invention controls system.
The specific embodiment
Referring to Fig. 1:
After evaporator temperature sensor was used for judging the refrigerator energising, refrigerator belonged to energising or first "on" position again.Master control borad is different according to state, delays time to get into defrost in 4 hours or 10 hours.
After defrost first finished, master control borad was that loop cycle clocks with 24 hours.
Be the signal input during this time with the door switch.
If there is continuous situation of closing the door in 4 hours to occur, then master control borad control defrosting system is shut down the back at press and is got into defrost.Remaining time in cycle, can not get into defrost for the second time again.
If there is not continuous situation of closing the door in 4 hours to occur, then master control borad control defrosting system selects the moment of first shutdown of press to get into defrost in the ensuing cycle.Remaining time in cycle, can not get into defrost for the second time again.
