The predicted defrosting interval time is equal to a difference value obtained by subtracting a product of a first preset defrosting time multiple and the accumulated time length of N times of opening of the door body from a preset fixed defrosting period; wherein N is the accumulated opening times. The defrosting interval compensation value is equal to the product of the accumulated time length of the last m times of opening of the door body and a second preset defrosting time multiple; wherein m=n-N, N is the accumulated opening times, and N is the threshold of the opening times.

In the prior art, under the condition that the door opening times exceeds the door opening times threshold, the predicted defrosting interval time is required to be calculated, then the defrosting interval compensation value is calculated, and finally the defrosting interval compensation value is used for compensating the predicted defrosting interval time, so that the calculation process is complicated.

The embodiment of the disclosure provides a method, a device, a refrigeration device and a storage medium for controlling the refrigeration device, which can more reasonably control the time for starting defrosting and have a relatively simple determination mode.

In some embodiments, the present disclosure provides a method for controlling a refrigeration appliance, as shown in fig. 1, comprising:

s101, the refrigerating equipment acquires the equipment operation time length for starting defrosting in the previous judgment.

And S103, operating the defrosting device under the condition that the time from the end of the previous defrosting reaches the operation duration of the device for starting defrosting in the current judgment.

The defrosting interval time can be dynamically adjusted by determining the equipment operation time for starting defrosting according to the equipment operation time for starting defrosting determined in the previous time. The excessively long defrosting interval is reduced to affect the use, or the excessively short defrosting interval time causes excessive power consumption. Thus, not only is the calculation process simplified, but also the time for controlling and starting defrosting is more reasonable.

And calculating the operation time of the refrigeration equipment from the time when the defrosting is started to the time when the refrigeration equipment is started to the time when the defrosting is started.

In some embodiments, the refrigeration equipment includes a door body and a door body sensor, the door body sensor is arranged on the door body and is used for sensing the opening and closing of the door body, as shown in fig. 2, the refrigeration equipment determines the equipment operation duration for starting defrosting according to the equipment operation duration for starting defrosting in the previous time, and the refrigeration equipment includes:

By determining the equipment operation time length for starting defrosting according to t and t1 and the equipment operation time length for starting defrosting in the previous judgment, the interval time of defrosting can be flexibly adjusted, the situations of excessive defrosting and insufficient defrosting are reduced, and the calculation process is simplified.

Because the door opening can cause frosting to increase, the equipment operation time for judging starting defrosting is adjusted according to the door opening time, the defrosting interval can be reduced under the condition of long door opening time, and the defrosting interval is increased under the condition of short door opening time, so that the conditions of more defrosting or insufficient defrosting are reduced.

In some embodiments, the unit time is one hour or half an hour.

In some embodiments, when the refrigeration equipment is in operation refrigeration during door opening, the duration of the door opening is determined to be the actual door opening duration multiplied by a constant K which is greater than 1.

The door is opened when the refrigerator is operated, the door opening time is increased by a certain amount when the door opening time is determined, and when the defrosting interval is determined, the door opening can be increased by considering that the frosting is increased under the refrigeration condition, and the door opening time is increased at the moment, so that the defrosting interval time is adjusted. The interval time of defrosting is shortened, so that the condition of insufficient defrosting is reduced.

In some embodiments, the refrigeration device further includes a heating component, configured to heat air entering the door body to defrost, where the refrigeration device determines, according to t and t1 and a device operation duration for starting defrosting determined previously, a device operation duration for starting defrosting determined this time, including:

By controlling the change of the defrosting interval time according to the door opening time, when the door opening time is longer, the situation of excessive defrosting and insufficient defrosting can be reduced due to the fact that the frosting is increased and the defrosting interval time is relatively reduced, and the calculation process is simplified.

In some embodiments, theWhere n is a unit time, T2 is a longest heating time interval of a heating element in the refrigeration equipment, and T1 is a shortest heating time interval of the heating element in the refrigeration equipment.

In some embodiments, the initial value of the running time of the equipment for starting defrosting in the judgment of the refrigeration equipment is the longest heating time interval of the heating assembly in the refrigeration equipment.

By initially taking the longest heating time interval of the heating assembly within the refrigeration appliance as the defrost interval, it is possible to reduce excessive defrost in view of less frosting initially.

In some embodiments, the maximum value of the running time of the device for starting defrosting is the longest heating time interval of the heating component in the refrigeration device, and the minimum value of the running time of the device for starting defrosting is the shortest heating time interval of the heating component in the refrigeration device. As shown in fig. 3, the method provided by the embodiment of the disclosure further includes:

and S301, determining the equipment operation time length for starting defrosting by the judgment as the longest heating time interval of the heating assembly in the refrigeration equipment under the condition that the determined equipment operation time length for starting defrosting by the judgment is longer than the longest heating time interval of the heating assembly in the refrigeration equipment.

S302, when the determined equipment operation time for starting defrosting is smaller than the shortest heating time interval of the heating assembly in the refrigeration equipment, the refrigeration equipment determines the equipment operation time for starting defrosting as the shortest heating time interval of the heating assembly in the refrigeration equipment.

By setting the maximum value and the minimum value of the defrosting interval, the situation that the heating assembly is damaged due to the fact that the defrosting interval is too small can be reduced, and the situation that defrosting is insufficient due to the fact that the defrosting interval is too long can be reduced.

As shown in fig. 4, an embodiment of the present disclosure further provides a method for controlling a refrigeration apparatus, including:

s401, the refrigeration equipment acquires the equipment operation time length for starting defrosting in the previous judgment.

S402, the refrigeration equipment acquires the total door opening time t within unit time from the end of the previous defrosting.

S403, the refrigeration equipment acquires the total door opening time t1 within unit time from the end of defrosting again before;
