The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
A control method of the air-cooled refrigerator according to the first aspect of the present invention will be described with reference to fig. 1.
The control method of the air-cooled refrigerator according to the first aspect of the invention comprises the following steps: judging whether the air-cooled refrigerator meets defrosting conditions or not in the refrigerating process of the air-cooled refrigerator; if the defrosting condition is met, controlling a compressor of the air-cooled refrigerator to shut down, simultaneously controlling a freezing fan of the air-cooled refrigerator to continue to operate, and judging whether the freezing fan meets the shutdown condition in real time; and if the freezing fan meets the stop condition, controlling the freezing fan to stop, controlling the air-cooled refrigerator to enter a defrosting mode, and starting a defrosting device to defrost.
Specifically, the method comprises the following steps: firstly, judging whether the air-cooled refrigerator meets the defrosting condition, controlling the compressor to stop when the air-cooled refrigerator meets the defrosting condition, namely controlling the air-cooled refrigerator to stop refrigerating to prevent frost accumulation on the evaporator from being aggravated, controlling the freezing fan to continue to operate at the moment, and blowing the residual cold on the evaporator into the freezing chamber of the air-cooled refrigerator after the compressor is stopped, so that the residual cold of the evaporator can be fully utilized, pre-refrigerating the freezing chamber can be realized, food deterioration caused by large temperature rise of the freezing chamber in the defrosting process can be prevented, and the compressor can be ensured to operate for a short time to enable the temperature of the freezing chamber to reach the freezing temperature after the refrigerator enters the refrigerating mode again.
It should be emphasized that, in the process of continuing the operation of the freezing fan, it is necessary to detect and judge whether the freezing fan meets the stop condition in real time, so as to control the stop of the freezing fan in real time, for example, the stop condition of the freezing fan may be set as that the temperature of the freezing compartment rises by 1.5 degrees centigrade, that is, the freezing fan is considered to reach the stop condition, at this time, the freezing fan is controlled to stop, and the air-cooled refrigerator is controlled to enter the defrosting mode and the defrosting device is turned on for defrosting, but the invention is not limited thereto, and the temperature of the freezing compartment may also start to rise again, that is, the freezing fan is considered to reach the stop condition.
Therefore, the frosting amount of the freezing evaporator is different when the freezing defrosting is carried out at each time due to external factors such as different environmental temperatures and different humidities, the residual cold amount of the evaporator is different after the compressor is shut down, the shutdown time of the freezing fan is judged and controlled in real time in the embodiment, compared with the setting of fixed time for the continuous operation of the freezing fan in the related technology, the waste of the cold amount caused by that the cold air possibly flows into the freezing chamber incompletely due to the fact that the cold amount of the evaporator is more and the operation of the freezing fan is fixed for a certain time can be avoided, and the phenomenon that the rising amplitude of the temperature of the freezing chamber caused by the fact that the operation of the defrosting device is overlapped again and the operation of the freezing fan is larger and the storage effect of food in the freezing chamber is influenced due to the fact that the cold amount of the evaporator is more and the operation of the freezing fan is fixed for a certain time when the cold amount of the evaporator is less and the operation of the freezing fan is less can be avoided.
According to the control method of the air-cooled refrigerator in the first aspect of the invention, the stop of the freezing fan is controlled by judging the stop time of the freezing fan in real time, so that after the air-cooled refrigerator enters a defrosting mode and the compressor stops running, the air-cooled refrigerator can fully utilize the residual cold energy of the evaporator to perform pre-cooling on the freezing chamber, thereby preventing the food from deteriorating due to large temperature change of the freezing chamber caused by defrosting, and ensuring that the temperature of the freezing chamber can reach the freezing temperature only by running the compressor for a short time after the refrigerator enters the refrigerating mode again.
Further, judge that freezing fan whether satisfies the shut down condition, include: judging whether the temperature of the freezing chamber rises or not; if the temperature of the freezing chamber rises, controlling the freezing fan to stop and starting the defrosting device to defrost, wherein the temperature of the freezing chamber can be used for measuring whether the residual cold quantity of the evaporator is fully utilized, and specifically, after the compressor stops, the residual cold quantity of the evaporator is blown into the freezing chamber by the freezing fan, and the temperature of the freezing chamber begins to rise because insufficient cold quantity continuously enters the freezing chamber; if the residual cold of the evaporator is not completely blown into the freezing chamber, the temperature fluctuation can not be caused because of continuous cold supplement in the freezing chamber before all the cold is completely blown into the freezing chamber.
Further, determining whether the temperature of the freezer compartment has risen comprises: judging whether a freezing door of the freezing chamber is opened or not in the process of continuing the operation of the freezing fan; if the freezing door of the freezing chamber is opened, detecting and judging whether the temperature of the freezing chamber rises or not in real time 2-5 minutes after the freezing door is closed, so that the interference of the factor of transient temperature rise of the freezing chamber caused by opening of the cold eastern door can be eliminated; and if the freezing door of the freezing chamber is not opened, detecting and judging whether the temperature of the freezing chamber rises in real time, and controlling the freezing fan to stop and the defrosting device to start to operate to defrost after the temperature of the freezing chamber rises. Therefore, the time for starting the operation of the defrosting device of the air-cooled refrigerator can be more accurate.
Preferably, if the freezing door of the freezing chamber is opened during the continuous operation of the freezing fan, the temperature of the freezing chamber is monitored and judged to be increased in real time after the freezing door is closed for 3 minutes.
According to some embodiments of the invention, the determining whether the air-cooled refrigerator meets the defrosting condition comprises: judging whether the accumulated refrigerating time of the air-cooled refrigerator in the refrigerating mode reaches a first preset time or not; if the first preset time is reached, judging that the air-cooled refrigerator meets a defrosting condition, specifically, the defrosting condition can be measured by the running time of the compressor, and since the air-cooled refrigerator is always in running under the refrigeration mode, setting the first preset time for the compressor from entering the refrigeration mode to entering the defrosting mode, and when the accumulated running time of the compressor reaches the set first preset time, determining that the air-cooled refrigerator meets the defrosting condition; it should be noted that the first preset time set for any type of air-cooled refrigerator can be scientifically calculated by counting the time required by the air-cooled refrigerator of the type from entering the cooling mode to accumulating frost to a certain extent on the evaporator for a plurality of times.
The defrosting condition of the air-cooled refrigerator is that the weight change value of the evaporator reaches a set value, for example, the weight change value of the evaporator can be measured by a gravity sensor to determine the amount of frost accumulated on the evaporator, and when the weight change value of the evaporator reaches the set value, the air-cooled refrigerator is controlled to enter the defrosting mode.
