[0028] In order to be able to understand the features and technical content of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the drawings. The attached drawings are for reference and illustration only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the sake of explanation, multiple details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, well-known structures and devices can be shown in a simplified manner.

[0029] In the specification, claims and above-mentioned drawings of the embodiments of the present disclosure, terms such as "first", "second", etc. are used to distinguish similar objects and do not have to be used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so as to implement the embodiments of the present disclosure described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0030] Unless otherwise specified, the term "plurality" means two or more.

[0031] In the embodiments of the present disclosure, the character " / " indicates that the objects before and after are in an "or" relationship. For example, A / B means: A or B.

[0032] The term "and / or" describes the relationship between objects and indicates that three relationships can exist. For example, A and / or B means: A or B, or, the three relationships of A and B.

[0033] The term "corresponding" can refer to an associated relationship or a binding relationship. A corresponding to B means that there is an associated relationship or a binding relationship between A and B.

[0034] It should be noted that, without conflict, the embodiments in the present disclosure and the features in the embodiments can be combined with each other.

[0035] Combined with Figure 1 As shown, a refrigerator 1 is provided. The refrigerator 1 includes a freezing compartment 20 and a refrigerating compartment 10, and a refrigerating air damper is provided between the freezing compartment 20 and the refrigerating compartment 10. The freezing compartment 20 includes a freezing fan. The refrigerator 1 further includes a compressor and an electric control device. The electric control device includes a processor, and the processor is used to control the compressor, the freezing fan, etc. to realize various functions of the refrigerator 1.

[0036] Combined with Figure 1 the refrigerator shown, an embodiment of the present disclosure provides a method for controlling a refrigerator, as Figure 2 shown, the method includes:

[0037] S201, the processor obtains the working state of the refrigerating air damper.

[0038] Among them, the working state includes a fault state. The fault state means that the refrigerating air damper cannot be closed.

[0039] S202, when the working state of the refrigerating air damper is a fault state, the processor obtains the refrigerating temperature of the refrigerating compartment and controls the start and stop of the compressor according to the refrigerating temperature.

[0040] It can be understood that usually the start and stop of the compressor are controlled by the freezing temperature of the freezing compartment, which refers to the process of the compressor from starting to stopping. But in this step, that is, when the working state of the refrigerating air damper is a fault state, the start and stop of the compressor are controlled by the refrigerating temperature of the refrigerating compartment.

[0041] S203, the processor determines the start and stop cycle of the compressor, and obtains the freezing temperature of the freezing compartment within the start and stop cycle, and the current duty ratio of the freezing fan.

[0042] S204, the processor controls the duty ratio of the freezing fan according to the freezing temperature within the start and stop cycle and the current duty ratio of the freezing fan.

[0043] By using the method for controlling a refrigerator provided in the embodiments of the present disclosure, since the refrigeration air damper fails, the cold air flow between the refrigerating compartment and the freezing compartment cannot be adjusted, resulting in excessive refrigeration in the refrigerating compartment. Therefore, when the working state of the refrigeration air damper is a fault state, the start and stop of the compressor are controlled according to the refrigerating temperature, and the duty ratio of the freezing fan is controlled by the freezing temperature within the start-stop cycle and the current duty ratio of the freezing fan, so as to avoid excessive refrigeration of the refrigerating temperature in the refrigerating compartment while ensuring that the freezing compartment meets the user's demand for the freezing temperature, thereby improving the refrigeration effect of the entire refrigerator and the user's experience.

[0044] Optionally, the processor controls the duty ratio of the freezing fan according to the freezing temperature within the start-stop cycle and the current duty ratio of the freezing fan, including: the processor obtains the integrated average temperature of the freezing temperature within the start-stop cycle. The processor obtains the temperature difference between the integrated average temperature and the target freezing temperature. The processor adjusts the duty ratio of the freezing fan according to the temperature difference and the current duty ratio of the freezing fan.

[0045] Wherein, the temperature difference represents the integrated average temperature - the target freezing temperature.

[0046] Exemplarily, the target freezing temperature refers to the temperature required by the freezing compartment, and the value range of the target freezing temperature is [-26°C, -16°C]. Specifically, the target freezing temperature is set to -16°C, -20°C or -26°C. The target freezing temperature can be set according to the actual needs of the user and is not limited herein.

[0047] In the embodiments of the present disclosure, within the start-stop cycle, the freezing temperatures at multiple moments are continuously obtained, and an integral operation is performed on the freezing temperatures at these multiple moments to obtain the integrated average temperature within the start-stop cycle. This integrated average temperature can reflect the overall trend and stability of the temperature change in the freezing compartment, and can better reflect the actual temperature state of the freezing compartment compared to a single instantaneous freezing temperature value. The calculated integrated average temperature is compared with the target freezing temperature to obtain the temperature difference between the two. This temperature difference can indicate the refrigeration situation of the freezing compartment. For example, there may be a risk of overcooling in the freezing compartment or the refrigeration efficiency may be insufficient. Therefore, the duty ratio of the freezing fan is adjusted according to the temperature difference and the current duty ratio of the freezing fan to ensure the refrigeration effect of the freezing compartment.

[0048] Optionally, the processor adjusts the duty cycle of the refrigeration fan according to the temperature difference and the current duty cycle of the refrigeration fan, including: when the temperature difference is greater than the preset temperature difference and the current duty cycle of the refrigeration fan is greater than the first preset duty cycle, the processor controls the duty cycle of the refrigeration fan to decrease by a second preset duty cycle. When the temperature difference is less than or equal to the preset temperature difference and the current duty cycle of the refrigeration fan is greater than the first preset duty cycle, the processor controls the refrigeration fan to continue running at the current duty cycle. When the temperature difference is greater than the preset temperature difference and the current duty cycle of the refrigeration fan is less than or equal to the first preset duty cycle, the processor controls the target refrigeration temperature of the refrigerated compartment to decrease by the preset temperature.

[0049] Exemplarily, the value range of the preset temperature difference is [2°C, 4°C]. Specifically, the preset temperature difference can be set to 2°C, 3°C or 4°C. More specifically, the preset temperature difference can be set to 3°C. This preset temperature difference is a critical value used to determine the risk of possible overcooling in the refrigerated compartment or the possible insufficient refrigeration efficiency.

[0050] Exemplarily, the value range of the first preset duty cycle is [45%d, 55%d], where d is the maximum duty cycle of the refrigeration fan. Specifically, the first preset duty cycle can be set to 50%d.

[0051] Exemplarily, the value range of the second preset duty cycle is [3%d, 6%d]. Specifically, the second preset duty cycle can be set to 5%d.

[0052] Exemplarily, the processor determines the second preset duty cycle in the following manner: the processor calculates D2 = (D - D1) × a to obtain the second preset duty cycle. Where D2 is the second preset duty cycle, D is the current duty cycle of the refrigeration fan, D1 is the first preset duty cycle, and a is the adjustment coefficient.

[0053] Exemplarily, the value range of a is [0.005, 0.015]. Specifically, a can be set to 0.005, 0.01 or 0.015. In this way, the adjustment of the second preset duty cycle can be made more accurate.

[0054] Exemplarily, the target refrigeration temperature refers to the temperature required for the refrigerated compartment, and the value range of the target refrigeration temperature is [0°C, 8°C]. Specifically, the target refrigeration temperature is set to 0°C, 4°C or 8°C. The target refrigeration temperature can be set according to the actual needs of the user and is not limited here.

[0055] Exemplarily, the value range of the preset temperature can be [0.5°C, 1.5°C]. Specifically, the preset temperature is set to 0.5°C, 1°C or 1.5°C.

[0056] It should be noted that the start and stop of the refrigeration fan are consistent with the start and stop of the compressor.

[0057] It should be noted that when the target refrigeration temperature of the refrigerated compartment is reduced by a preset temperature until the temperature difference is less than or equal to the preset temperature difference, or the reduced target refrigeration temperature is equal to the lowest target refrigeration temperature, the control to reduce the target refrigeration temperature of the refrigerated compartment by the preset temperature will no longer be performed. Among them, the lowest target refrigeration temperature can be set to 0°C.

[0058] In this disclosed embodiment, when the temperature difference is greater than the preset temperature difference and the current duty ratio of the refrigeration fan is greater than the first preset duty ratio, it indicates that the refrigeration temperature of the refrigerated compartment is relatively high. At this time, the duty ratio of the refrigeration fan is reduced to extend the working time of the refrigeration fan, thereby achieving long-term refrigeration of the refrigerated compartment, and then reducing the refrigeration temperature of the refrigerated compartment to make the refrigeration temperature approach the target refrigeration temperature. When the temperature difference is less than or equal to the preset temperature difference, and the current duty ratio of the refrigeration fan is still greater than the first preset duty ratio, it indicates that the current refrigeration temperature can meet the refrigeration requirements of the refrigerated compartment. Then, the current duty ratio of the refrigeration fan is maintained to continue running to ensure that the refrigeration temperature is stable within an appropriate range. When the temperature difference is greater than the preset temperature difference, but the current duty ratio of the refrigeration fan is already at or below the first preset duty ratio, at this time, to avoid the refrigeration fan from not rotating, the current duty ratio of the refrigeration fan will no longer be reduced. Instead, the target refrigeration temperature of the refrigerated compartment is lowered by a preset temperature value to extend the refrigeration duration of the compressor, thereby reducing the temperature of the refrigerated compartment. In this way, while ensuring that the refrigeration temperature of the refrigerated compartment is within the range of the target refrigeration temperature, the refrigeration effect of the refrigerated compartment can be improved, the working states of different compartments of the refrigerator can be accurately adjusted to meet the corresponding food storage conditions, and the user experience can be enhanced.

[0059] Optionally, the processor controls the start and stop of the compressor according to the refrigeration temperature, including: when the refrigeration temperature is less than the target refrigeration temperature, the processor controls the compressor to stop. And / or, when the refrigeration temperature is greater than or equal to the target refrigeration temperature, the processor controls the compressor to start.

[0060] Since before the working state of the refrigeration air damper is in a fault state, the start and stop of the compressor are usually controlled according to the refrigeration temperature of the refrigerated compartment. In this disclosed embodiment, when the working state of the refrigeration air damper is in a fault state, the control of the compressor start and stop is switched from the refrigeration temperature control to the refrigeration temperature control. In this way, the refrigeration effects of the refrigerated compartment and the refrigerated compartment can be improved, especially to avoid excessive refrigeration of the refrigerated compartment.

[0061] Optionally, the processor obtains the working state of the refrigeration air damper in the following manner: the processor obtains the refrigeration temperature of the refrigerated compartment. When the refrigeration temperature is less than the target refrigeration temperature, the processor obtains the change of the refrigeration temperature within a preset duration. The processor determines the working state of the refrigeration air damper according to the change of the refrigeration temperature within the preset duration.

[0062] Combine Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0063] S301: The processor obtains the refrigeration temperature of the refrigeration compartment.

[0064] S302: When the refrigeration temperature is lower than the target refrigeration temperature, the processor obtains a change in the refrigeration temperature within a preset time period.

[0065] S303: The processor determines the working state of the refrigeration damper according to the change of the refrigeration temperature within a preset time period.

[0066] S304: When the refrigeration damper is in a faulty state, the processor obtains the refrigeration temperature of the refrigeration compartment and controls the start and stop of the compressor according to the refrigeration temperature.

[0067] S305: The processor determines the on / off cycle of the compressor, and obtains the freezing temperature of the freezing compartment during the on / off cycle, and the current duty cycle of the freezing fan.

[0068] S306: The processor controls the duty cycle of the refrigeration fan according to the refrigeration temperature in the on-off cycle and the current duty cycle of the refrigeration fan.

[0069] In this disclosed embodiment, if the refrigerated temperature is lower than the target refrigerated temperature, it indicates that the refrigerated temperature is lower than the user's desired refrigerated temperature, which means that the refrigerated compartment is oversupplied with cold air. In this case, the operating status of the refrigerated damper can be more accurately determined based on the change in refrigerated temperature.

[0070] Optionally, the processor determines the working state of the refrigeration damper according to the change of the refrigeration temperature within a preset time period, including: when the refrigeration temperature obtained by the processor at a later moment within the preset time period is less than the refrigeration temperature obtained at a previous moment, the processor determines that the working state of the refrigeration damper is a fault state.

[0071] For example, the preset duration ranges from [8 minutes, 12 minutes]. Specifically, the preset duration can be set to 8 minutes, 10 minutes, or 12 minutes. More specifically, the preset duration can be set to 10 minutes. By setting the preset duration to the above range, changes in the refrigeration temperature can be accurately and timely obtained, thereby determining the operating status of the refrigeration damper.

[0072] Combine Figure 4 As shown, the embodiment of the present disclosure provides another method for controlling a refrigerator, comprising:

[0073] S401: The processor obtains the refrigeration temperature of the refrigeration compartment.

[0074] S402. When the refrigeration temperature is lower than the target refrigeration temperature, the processor obtains the change of the refrigeration temperature within a preset time period.

[0075] S403. When the refrigeration temperature obtained at a later moment within the preset time period is lower than the refrigeration temperature obtained at the previous moment, the processor determines that the working state of the refrigeration air damper is a fault state.

[0076] S404. When the working state of the refrigeration air damper is a fault state, the processor obtains the refrigeration temperature of the refrigerated compartment and controls the start and stop of the compressor according to the refrigeration temperature.

[0077] S405. The processor determines the start and stop cycle of the compressor, and obtains the freezing temperature of the freezer compartment within the start and stop cycle, as well as the current duty ratio of the freezer fan.

[0078] S406. The processor controls the duty ratio of the freezer fan according to the freezing temperature within the start and stop cycle and the current duty ratio of the freezer fan.

[0079] In this disclosed embodiment, when the refrigeration temperature obtained at a later moment within the preset time period is lower than the refrigeration temperature obtained at the previous moment, it indicates that the refrigeration temperature of the refrigerated compartment is continuously decreasing. At this time, it can be accurately determined that the refrigeration air damper is in a fault state.

[0080] Combined Figure 5 As shown, this disclosed embodiment provides a device 200 for controlling a refrigerator, including a first acquisition module 21, a first control module 22, a second acquisition module 23, and a second control module 24.

[0081] By using the device 200 for controlling a refrigerator provided in this disclosed embodiment, when the refrigeration air damper cannot be reset, while avoiding excessive refrigeration of the refrigerated compartment, it ensures the temperature requirement of the freezer compartment, improves the refrigeration effect of the refrigerator, and improves the user experience.
