Example 1
Fig. 1 is a flowchart of a defrost control method according to an embodiment of the present invention, as shown in fig. 1, comprising the steps of:
step S101, before the refrigerator enters a water dripping stage of a continuous defrosting period, acquiring door opening accumulated time and heating defrosting parameters;
step S102, determining the water dripping time of the water dripping stage of the continuous defrosting cycle according to the door opening accumulated time and the heating defrosting parameter.
In the embodiment, before the refrigerator enters the water dripping stage of the continuous defrosting period, the water dripping time is determined according to the door opening accumulated time and the heating defrosting parameters. The invention can determine proper water dripping time according to the current working condition of the refrigerator, thereby realizing the adaptive regulation and control of the water dripping time, realizing the accurate defrosting and water dripping, ensuring the complete defrosting of the surface of the evaporator, improving the defrosting effect of the refrigerator and improving the integral refrigerating efficiency of the refrigerator.
During operation, the refrigerator can circulate into a refrigeration cycle and a defrosting cycle, and a complete common defrosting cycle generally comprises: forced cooling stage-return air defrosting stage-heating defrosting stage-dripping stage. That is, the dripping phase is the last phase of the general defrosting cycle, and is switched to the cooling cycle after the dripping phase is completed. For the heating and defrosting phases in the defrosting cycle, it is possible that one heating and defrosting phase does not necessarily ensure complete defrosting of the surface of the evaporator, and a plurality of heating and defrosting phases need to be performed at this time, and the defrosting cycle in this case is called a continuous defrosting cycle, i.e. at least two heating and defrosting phases in one continuous defrosting cycle. For example, one continuous defrost cycle includes: strong cooling stage, return air defrosting stage, heating defrosting stage, small water dripping stage, small refrigeration stage, heating defrosting stage and water dripping stage. The drip phase is the last phase of the successive defrosting phase, and the refrigerating cycle is switched after the drip phase is completed.
The method can be realized by the following preferred embodiments when acquiring the door opening accumulated time: and starting from the end of the previous defrosting period (whether the normal defrosting period or the continuous defrosting period) to the time of entering the return air defrosting stage of the current continuous defrosting period, acquiring the door opening accumulated time in the period. The operation condition of the refrigerator is affected by the action of opening and closing the door of the refrigerator in the period, and further the subsequent defrosting is affected, so that the embodiment takes the accumulated time of opening the door as a reference parameter, and takes the influence of the accumulated time of opening the door on the dripping time of the dripping stage into consideration.
The heating defrosting parameters at least comprise: the defrosting heater is operated for a long time and continuously defrosting times. The method comprises the steps of obtaining heating defrosting parameters after the refrigerator enters a continuous defrosting period, and specifically: after the refrigerator enters a continuous defrosting period, the working time of a defrosting heater of each heating defrosting stage of the current continuous defrosting period is obtained, and the continuous defrosting times are recorded. Based on the method, the current defrosting condition can be clarified, and the accurate judgment of the dripping time of the subsequent dripping stage is facilitated.
After the door opening accumulated time, the defrosting heater working time and the continuous defrosting times are determined, determining the water dripping time of the water dripping stage of the continuous defrosting period according to the three parameters: determining corresponding first water dripping time according to the accumulated time of opening the door; determining corresponding second water dripping time according to the working time of the defrosting heater in each heating defrosting stage; judging whether the continuous defrosting times exceeds preset times or not, if so, determining third water dripping time; and taking the maximum value among the first dripping time, the second dripping time and the third dripping time, and determining the maximum value as the dripping time of the dripping stage.
It should be noted that a plurality of preset door opening time intervals may be preset, and a corresponding relationship between the preset door opening time intervals and the first water dripping time may be set. When the corresponding first water dripping time is determined according to the door opening accumulated time, a preset door opening time interval in which the door opening accumulated time is located is determined, and then the corresponding first water dripping time is determined according to the preset door opening time interval. Based on this, the first water-drop time related to the door-open cumulative time can be accurately and quickly determined.
A plurality of preset defrosting intervals can be preset, and the corresponding relation between the preset defrosting intervals and the second water dripping time is set. When determining the corresponding second water dripping time according to the working time of the defrosting heater of each heating defrosting stage, determining a preset defrosting interval in which the working time of the defrosting heater of each heating defrosting stage is positioned, and determining the corresponding second water dripping time according to the preset defrosting interval; wherein, the corresponding relation between the preset defrosting interval and the second water dripping time is preset. Based on the method, the second water dropping time related to the working time of the defrosting heater can be accurately and quickly determined, and when a plurality of heating defrosting stages exist, a plurality of second water dropping times can be obtained.
In addition to considering the influence of the above parameters on the drip time, it may be determined whether the operation time of the defrosting heater for a plurality of (preset number, e.g., 3) heating defrosting stages in succession exceeds the preset heating time, and if so, a fourth drip time is determined; and then, taking the maximum value among the first dripping time, the second dripping time, the third dripping time and the fourth dripping time, and determining the maximum value as the dripping time of the dripping stage. That is, if the working time of the defrosting heater in a plurality of continuous heating defrosting stages exceeds the preset heating time, the defrosting requirement is larger, and more water is generated after defrosting, so that more dripping time is needed to ensure that all dripping water is completely dripped.
After proper dripping time is determined according to the current working condition of the refrigerator, entering a dripping stage of a continuous defrosting period after the preset dripping condition is met, and maintaining the dripping time; and then, exiting the continuous defrosting period and entering the refrigerating period. The preset dripping condition includes at least one of the following conditions: the accumulated defrosting heater operation times of the continuous defrosting period exceeds the preset heating times (for example, 3 times); the defrosting heater operating time of a certain heating defrosting stage of the continuous defrosting cycle exceeds a preset time threshold (for example 55 min); the temperature of the defrosting sensor of the freezing chamber of the refrigerator reaches the preset exit temperature. The defrosting sensor is located at the back of the freezing chamber, not inside the freezing chamber, and it is understood that the defrosting sensor detects the temperature near the evaporator. After entering the drip stage, the defrosting heater is turned off, other core loads (such as a refrigerating fan, a compressor and the like) of the refrigerator are kept as they are, and the other core loads are turned off in the non-working state when the defrosting stage is heated, so that the above-mentioned kept as they are, namely, kept in the non-working state.

step S201, detecting a door opening cumulative time, specifically, detecting a door opening cumulative time in the following period: starting from the end of the previous defrost cycle (whether it is a normal defrost cycle or a continuous defrost cycle) to the time of entering the return-to-air defrost phase of the current continuous defrost cycle. And judging the door opening accumulated time and the door opening accumulated time threshold, namely setting two preset door opening time intervals based on the door opening accumulated time threshold in the embodiment.
In step S202, if the door open accumulated time is less than the door open accumulated time threshold, the corresponding drip time T1 is determined.
Step S203, if the door opening accumulated time is not less than the door opening accumulated time threshold, determining the corresponding dripping time T2.

And judging the working time of the defrosting heater and the defrosting heating time threshold, namely setting two preset defrosting intervals based on the defrosting heating time threshold in the embodiment. And judging whether the working time of the defrosting heater in a plurality of continuous heating defrosting stages is longer than the preset heating time.
In step S302, if the operation time of the defrosting heater for a plurality of (e.g., 3) continuous heating defrosting stages is greater than the preset heating time, the corresponding dripping time T5 is determined.
In step S303, if the operation time of the defrosting heater is less than the defrosting heating time threshold, the corresponding dripping time T3 is determined.
Step S304, if the working time of the defrosting heater is more than or equal to the defrosting heating time threshold, determining the corresponding dripping time T4.
Fig. 4 is a flowchart of determining a drip time according to a number of consecutive frostings according to an embodiment of the present invention, as shown in fig. 4, the flowchart including:
step S401, detecting the number of consecutive defrosting, specifically, detecting the number of consecutive defrosting before entering the dripping stage in the current consecutive defrosting cycle.
Step S402, if the number of continuous defrosting is more than or equal to 2, determining the corresponding dripping time T6.
In step S403, if the number of consecutive defrosting times is < 2, the drip time does not need to be determined.
Fig. 5 is a flowchart of final determining a drip time according to an embodiment of the present invention, as shown in fig. 5, the flowchart including:
in preparation for entering the drip phase, the drip times T1, T2, T3, T4, T5, T6 are obtained based on the above several preferred embodiments. Taking the maximum value of the above 6 dripping times as the final dripping time, and entering a dripping stage. And after the water dripping time, the water dripping stage is exited, namely the continuous defrosting period is ended, and the refrigerating period is entered.
Based on the control flows, the proper water dripping time is determined according to the current working condition of the refrigerator, so that the adaptive regulation and control of the water dripping time are realized, and the accurate defrosting and water dripping are realized. During the operation of the refrigerator, when the accumulated defrosting heater operation times of the continuous defrosting cycles exceeds the preset heating times (for example, 3 times), and/or the defrosting heater operation time of a certain heating defrosting stage of the continuous defrosting cycles exceeds the preset time threshold (for example, 55 min), and/or the defrosting sensor temperature of the freezing chamber of the refrigerator reaches the preset exit temperature, the condition that the water dripping stage is needed to be entered is indicated. If the freezer defrost sensor temperature is too low (below the preset exit temperature), indicating that the defrost is not clean, continuous defrost is required.
The proper drip time, in particular, the drip time, needs to be determined before entering the drip phase: and determining the dripping time according to the accumulated time of opening the door, the working time of the defrosting heater and the like. When the door opening accumulated time is smaller than the accumulated door opening time threshold, the dripping time (T1) is obtained. And obtaining dripping time (T2) when the accumulated door opening time is greater than or equal to the accumulated door opening time threshold. When the single operation time of the defrosting heater is smaller than the defrosting heating time threshold, the dripping time is obtained (T3). And when the single working time of the defrosting heater is larger than or equal to the defrosting heating time threshold value, obtaining dripping time (T4). And obtaining dripping time (T5) when the working time of the defrosting heater for the continuous multiple times is larger than the working time threshold value of the defrosting heater for the continuous multiple times. When continuous defrosting occurs, a drip time is obtained (T6). And taking the maximum value of the dripping time as the dripping time of the dripping stage.
After entering the drip stage, the defrosting heater is turned off, and other loads (a refrigerating fan, a compressor and the like) are maintained as they are, namely, a non-working state is maintained. And after the water dripping time, the water dripping stage is exited, the continuous defrosting period is ended, and the refrigerating period is switched.
