[0050] Traditional refrigerator damper heating systems usually work by timing or temperature sensing. These methods cannot accurately control the working state of the heating element, resulting in energy waste or the icing problem cannot be solved in time.

[0051] The embodiment of the present application provides a refrigerator and a control method, a control device and a storage medium thereof to solve the problem of large energy waste in the existing refrigerator damper heating. Figure 1-5 Provide explanation.

[0052] The refrigerator control method provided in the embodiment of the present application can be applied to a refrigerator. For example, please refer to Figure 1 , Figure 1A flowchart of a refrigerator control method provided in an embodiment of the present application. The refrigerator is provided with a damper and a heating element, and the heating element is used to heat and de-ice the damper. Common heating elements include heating wires (resistance wires), electric heating tubes, heating plates, heating rods, etc. The refrigerator control method includes:

[0053] S101: Detecting the operating status of the damper;

[0054] For example, the operating status of the refrigerator damper is monitored in real time by a sensor or other detection device. The sensor can detect parameters such as the temperature, humidity, and motor current of the damper to determine whether the damper is in a frozen state and promptly detect whether the damper is frozen so that corresponding measures can be taken.

[0055] S102: when the damper is in an icing state, obtaining a target operating mode of the heating element; wherein the heating element includes at least two different preset operating modes, and the target operating mode is one of the preset operating modes;

[0056] Among them, the power / power adjustment strategies corresponding to different preset working modes are different. In this embodiment, the refrigerator may be equipped with multiple preset working modes for users to choose from when leaving the factory. Users can select different preset working modes to control the operation of the heating element, and can also customize the working mode of the heating element to adjust the power of the heating element.

[0057] S103: Controlling the operation of the heating element based on the target working mode;

[0058] S104: When the operating state of the damper is a non-icing state, turn off the heating element.

[0059] In this step, when it is detected that the damper is in a non-freezing state, the heating element is controlled to be turned off to reduce energy consumption and save energy.

[0060] In an alternative embodiment, reference Figure 2 As shown, the preset working mode includes a first preset mode, and based on the target working mode, the operation of the heating element is controlled, including:

[0061] S201: When the target working mode is the first preset mode, obtaining a set temperature of the refrigeration compartment and an ice amount of the air door;

[0062] S202: Adjust the heating power of the heating element based on at least one of the set temperature and the amount of ice.

[0063] In this embodiment, the current set temperature of the refrigeration compartment can be obtained through a temperature sensor or user input. The set temperature is the temperature of the refrigeration compartment desired by the user and is also an important basis for determining the heating power of the heating element. The amount of ice on the damper can be detected by an ice sensor, which can be obtained by strategic ice layer thickness, area or mass.

[0064] Specifically, in an optional embodiment, the heating power of the heating element is adjusted based on at least one of the set temperature and the amount of ice, including: when the set temperature is greater than or equal to a preset temperature threshold, controlling the heating element to operate at a first power; when the set temperature is less than the preset temperature threshold, controlling the heating element to operate at a second power; wherein the first power is less than the second power.

[0065] In this embodiment, when the set temperature is less than the preset temperature threshold, it means that the temperature in the refrigeration room or the temperature expected by the user is low, and the heating power of the heating element needs to be increased to ensure that the damper does not freeze or melt the ice layer as soon as possible. On the contrary, when the set temperature is greater than or equal to the preset temperature threshold, it means that the temperature expected by the user and the temperature in the refrigeration room are high, and the possibility of ice formation and the amount of ice formation are low. The heating power of the heating element can be appropriately reduced to avoid the heating element consuming more energy and reduce energy consumption.

[0066] Furthermore, by setting different temperature levels, different temperature levels correspond to different heating powers, and the lower the temperature level, the higher the corresponding heating element power. Based on the temperature level corresponding to the set temperature, the heating power of the heating element can be adjusted accordingly to adapt to different refrigeration needs and freezing conditions.

[0067] In another optional embodiment, when the amount of ice formation is greater than or equal to a preset amount of ice formation, the heating element is controlled to operate at a third power; when the amount of ice formation is less than the preset amount of ice formation, the heating element is controlled to operate at a fourth power; wherein the third power is greater than the fourth power.

[0068] In this embodiment, when it is detected that the amount of ice on the damper is greater than or equal to the preset amount of ice, the system controls the heating element to operate at a higher power, aiming to quickly melt more ice and avoid affecting the normal operation of the damper; when it is detected that the amount of ice on the damper is less than the preset amount of ice, the system controls the heating element to operate at a relatively low power, reducing energy consumption and saving energy without affecting the operation of the damper. By detecting the amount of ice on the damper to flexibly adjust the power of the heating element to keep the amount of ice within an acceptable range, the deicing effect is guaranteed and unnecessary energy waste is avoided.

[0069] In another optional embodiment, the heating power of the heating element can be adjusted by comprehensively setting the temperature and the amount of ice, so that the heating power of the heating element can be more accurately adapted to different scenarios, improve deicing efficiency, and reduce unnecessary energy consumption.

[0070] For example, when the set temperature is high and the amount of ice is small, it can be considered that the current environment is relatively warm and the risk of ice is low, so the heating element is controlled to run at a lower power or turned off; when the set temperature is moderate and the amount of ice is moderate, the heating element can be maintained at medium power to keep the damper from ice and adapt to the current environment; when the set temperature is low and the amount of ice is large, it can be considered that the current environment is relatively cold and the risk of ice is high, so the heating element is controlled to run at a higher power to quickly melt the ice layer and prevent further ice formation; when the set temperature and the amount of ice do not match, for example, the set temperature is very high but the amount of ice is also large, it can be flexibly adjusted according to the specific situation. For example, priority can be given to eliminating the risk of ice formation, even if the heating element is run at a higher power for de-icing in a warm environment.

[0071] In an alternative embodiment, reference Figure 3 As shown, the preset working mode also includes a second preset mode, then based on the target working mode, the operation of the heating element is controlled, including:

[0072] S301: When the amount of ice is greater than or equal to a first preset threshold, controlling the heating element to operate at a fifth power;

[0073] S302: After the running time of the heating element reaches a preset time, the heating element is turned off.

[0074] In this embodiment, the second preset mode is an energy-saving mode, which is more energy-saving than the first preset mode. When the damper is not detected to be frozen, the heating element remains in a closed state to save energy; when the damper is detected to be in a frozen state and the amount of ice on the damper is greater than or equal to the first preset threshold, the heating element is controlled to operate at a fifth power, which is, for example, the lowest power preset for the heating element, and the heating element is controlled to automatically shut down after operating at the lowest power for a preset time, such as 3 minutes or 4 minutes, to prevent the heating element from being overheated and causing energy waste, so that it just does not affect the operation of the damper.

[0075] In an optional embodiment, after running the heating element at the lowest power for a preset time and turning off the heating element, the control method further includes: when the amount of ice is greater than or equal to a second preset threshold, turning on the heating element and controlling the heating element to operate in a first preset mode.

[0076] In this embodiment, after the heating element is operated in the second preset mode, if it is detected that the amount of ice is still greater than or equal to the second preset threshold, it means that the opening and closing of the damper may be affected. At this time, the system can switch the target working mode of the heating element and switch the heating element to operate in the first mode for de-icing, thereby improving the de-icing efficiency and preventing the damper from failing to work properly.

[0077] In an optional embodiment, the control method further includes: acquiring historical freezing data of the damper and historical power data of the heating element; and modifying the preset working mode based on the historical freezing data and the historical power data.

[0078] In this embodiment, an ice sensor or other detection device is used to record the historical ice data on the damper over the past period of time. The historical ice data may include key data such as the amount of ice, ice speed, and ice time, and record key data such as the operating power, operating time, and number of starts of the heating element over the past period of time.

[0079] Then analyze the historical icing data to identify the patterns and trends of icing, such as whether the amount of icing increases over time, whether the icing speed increases, etc., and evaluate the changes in icing conditions under different environmental conditions (such as temperature, humidity, wind speed, etc.). Analyze the historical power data of the heating element, evaluate the deicing effect of the heating element at different powers, and determine the optimal operating power and operating time of the heating element under different amounts of icing.

[0080] Then, based on the analysis results of the freezing data, the preset freezing amount thresholds (such as the first preset threshold and the second preset threshold in the above embodiment) are adjusted to more accurately reflect the current freezing conditions; based on the analysis results of the power data, the operation strategy of the heating element is optimized, such as adjusting the power level, operating time and start-up conditions of the heating element.

[0081] The revised working mode is applied to the system and its effect is continuously monitored. If the revised working mode can significantly improve de-icing efficiency and reduce energy consumption, it will be determined as the new preset working mode. Otherwise, historical data will be continuously obtained to optimize it.

[0082] During the operation of the revised working mode, the historical freezing data of the damper and the historical power data of the heating element will continue to be collected, and the collected data will be analyzed regularly to evaluate the effect of the revised working mode. Based on the evaluation results, the working mode will be further optimized and adjusted. Through the intelligent optimization mechanism, the system can continuously learn and adapt to different environmental conditions, thereby providing a more accurate and efficient de-icing solution.

[0083] The control method of the refrigerator provided in the embodiment of the present application is provided with a damper and a heating element, and the heating element is used to heat the damper. The control method includes: detecting the operating state of the damper; when the operating state of the damper is a frozen state, obtaining the target working mode of the heating element; wherein the heating element includes at least two different preset working modes, and the target working mode is one of the preset working modes; based on the target working mode, controlling the operation of the heating element; when the operating state of the damper is a non-frozen state, turning off the heating element. By detecting the operating state of the damper, the operation is started only when the damper is in a frozen state, and a plurality of different preset working modes are set for the user to choose, so that the heating element can operate according to the actual freezing state of the damper and the working mode set by the user, and the power of the heating element is intelligently adjusted to save energy.

[0084] In a second aspect, an embodiment of the present application provides a control device for a refrigerator, wherein the refrigerator is provided with a damper and a heating element, wherein the heating element is used to heat the damper. Figure 4 As shown, the control device of the refrigerator includes:

[0086] An acquisition module 402 is used to acquire a target operating mode of the heating element when the operating state of the damper is an icing state; wherein the heating element includes at least two different preset operating modes, and the target operating mode is one of the preset operating modes;

[0087] An operation module 403, used to control the operation of the heating element based on the target working mode;

[0088] The closing module 404 is used to close the heating element when the operating state of the damper is a non-icing state.

[0089] The refrigerator control device of the embodiment of the present application can be applied to the refrigerator to control the operation of the heater.

[0092] In an optional embodiment, the ice sensor is a thin-film ice sensor, which has the characteristics of high sensitivity, fast response, small size and high reliability. Multiple groups of electrode pairs are arranged at equal distances, and each electrode pair is used as an ice detection scale. The total ice thickness is equal to the product of the distance between adjacent electrode pairs and the number of electrode pairs whose medium is ice. Ice is detected by measuring the change in capacitance between electrodes. When an ice layer is formed on the electrode, the capacitance value will change, so that the presence and thickness of ice can be detected.

[0093] In an optional embodiment, the ice sensor is installed on the inner edge of the damper, that is, the side close to the refrigeration compartment, so that it can directly contact the ice layer that may be formed by the cold air and moisture in the refrigeration compartment, which helps the ice sensor to more accurately detect whether the edge of the damper begins to freeze, thereby providing timely ice information, ensuring that the heating element is started in time, and avoiding the damper from being unable to close or difficult to open due to excessive ice thickness.
