[0034] Figure 1 is a schematic diagram of a method for controlling a refrigerator provided by an embodiment of the present disclosure; Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling a refrigerator, comprising:

[0035] S11, the refrigerator determines the state information of the first temperature sensor according to the temperature values ​​collected by the first temperature sensor and the second temperature sensor respectively.

[0036] S12, the refrigerator determines a target control scheme for the refrigerator compressor according to the status information of the first temperature sensor.

[0037] S13, the refrigerator controls the refrigerator compressor to execute the target control scheme.

[0038] In this solution, the refrigerator is provided with a main control board and a frequency conversion board, the main control board and the frequency conversion board are connected through a bus, and the main control board and the frequency conversion board are arranged adjacent to each other. Among them, the main control board is provided with a first temperature sensor, and the frequency conversion board is provided with a second temperature sensor. Specifically, the refrigerator can obtain the temperature values ​​collected by the first temperature sensor and the second temperature sensor respectively. Further, the refrigerator can determine the status information of the first temperature sensor according to the temperature values ​​collected by the first temperature sensor and the second temperature sensor respectively. Here, the status information of the first temperature sensor includes fault or normal. In this way, the status information of the first temperature sensor can be accurately judged in combination with the temperature values ​​collected by the first temperature sensor and the second temperature sensor respectively.

[0039] Furthermore, after the refrigerator determines the status information of the first temperature sensor, the refrigerator can determine the target control scheme of the refrigerator compressor in combination with the status information of the first temperature sensor. Specifically, the refrigerator determines the target control scheme of the refrigerator compressor based on the status information of the first temperature sensor, including: when the status information of the first temperature sensor is faulty, the refrigerator determines that the target control scheme of the compressor is to control the refrigerator compressor to operate in a special mode; when the status information of the first temperature sensor is normal, the refrigerator determines that the target control scheme of the compressor is to control the refrigerator compressor to operate in a normal mode. In this way, the target control scheme of the compressor can be accurately determined in combination with the status information of the first temperature sensor, providing an accurate data basis for the control process of the compressor. Further, after the refrigerator determines the target control scheme, the refrigerator controls the compressor to execute the target control scheme.

[0040] A method for controlling a refrigerator provided by an embodiment of the present disclosure can accurately determine whether the first temperature sensor is faulty based on the temperature values ​​collected by the first temperature sensor and the second temperature sensor, and accurately determine the target control scheme of the refrigerator compressor based on actual conditions, thereby achieving precise control of the refrigerator while controlling the refrigerator to execute the target control scheme, avoiding inaccurate compressor control due to failure of the temperature sensor of the main control board, and effectively meeting the user's energy-saving control needs for the refrigerator.

[0041] Figure 2 is a schematic diagram of a method for determining a target control scheme provided by an embodiment of the present disclosure; Figure 2 As shown, optionally, in S12, the refrigerator determines a target control scheme for the refrigerator compressor according to the state information of the first temperature sensor, including:

[0042] S21, when the state information of the first temperature sensor is a fault, the refrigerator determines that a target control scheme of the refrigerator compressor is to control the refrigerator compressor to operate in a special mode.

[0043] S22, when the state information of the first temperature sensor is normal, the refrigerator determines that the target control scheme of the refrigerator compressor is to control the refrigerator compressor to operate in a normal mode.

[0044] In this solution, if it is determined that the status information of the first temperature sensor is a fault, it can be determined that the target control scheme of the refrigerator compressor is to control the refrigerator compressor to operate in a special mode. Here, the special mode is to perform periodic start and stop control on the compressor. Specifically, the start and stop strategy for each cycle is to control the compressor to run at a first speed for a first time, and then control the compressor to stop within a second time. As an example, the first speed is 3000r / min, the first time is 20 minutes, and the second time is 10 minutes. Optionally, the number of cycles in which the compressor operates in a special mode can be specifically determined based on actual conditions.

[0045] In this solution, when it is determined that the status information of the first temperature sensor is normal, it can be determined that the target control solution of the refrigerator compressor is to control the refrigerator compressor to operate in normal mode. Here, the normal mode includes the compressor start-up point normal mode and the compressor shutdown point normal mode. Specifically, the compressor start-up point normal mode includes controlling the compressor to operate at a first speed; the compressor shutdown point normal mode includes controlling the compressor to operate at a second speed. Among them, the first speed> the second speed. As an example, the first speed is 3000r / min and the second speed is 1800r / min.

[0046] With this solution, the target control solution of the compressor can be accurately determined in combination with the status information of the first temperature sensor, providing an accurate data basis for the control process of the compressor, so that the target control solution determined in this way is more in line with the status characteristics of the first temperature sensor.

[0047] Figure 3 is a schematic diagram of a method for determining status information provided by an embodiment of the present disclosure; Figure 3 As shown, S11, the refrigerator determines the state information of the first temperature sensor according to the temperature values ​​collected by the first temperature sensor and the second temperature sensor, including:

[0048] S31, when the first temperature sensor and the second temperature sensor meet the compressor startup condition, the refrigerator calculates the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor.

[0049] S32, the refrigerator determines the state information of the first temperature sensor according to the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor.

[0050] In this solution, the refrigerator can determine whether the first temperature sensor and the second temperature sensor meet the compressor startup condition in the following way: the refrigerator obtains the startup point temperature of the compressor; when the temperature values ​​collected by the first temperature sensor and the second temperature sensor reach the startup point temperature of the compressor, it is determined that the first temperature sensor and the second temperature sensor meet the compressor startup condition. As an example, the startup point temperature of the compressor in the refrigerator freezer compartment is -16°C. In this way, it is possible to accurately determine whether the first temperature sensor and the second temperature sensor meet the compressor startup condition.

[0051] Further, when the first temperature sensor and the second temperature sensor meet the compressor startup conditions, the temperature values ​​collected by the first temperature sensor and the second temperature sensor are respectively obtained, and the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor is calculated. For example, if the temperature value collected by the first temperature sensor is -16.3°C and the temperature value collected by the second temperature sensor is -16.5°C, the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor is 0.2°C. Further, after obtaining the difference, the refrigerator can determine the status information of the first temperature sensor in combination with the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor. In one example, the refrigerator can determine the difference range where the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor is located; and determine the status information corresponding to the difference range as the status information of the first temperature sensor. In this way, the status information of the first temperature sensor can be judged in combination with the fluctuation of the temperature data collected by multiple temperature sensors arranged at adjacent positions, so as to ensure the accuracy of the status information of the first temperature sensor.

[0052] Optionally, in S32, the refrigerator determines the state information of the first temperature sensor according to the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor, including:

[0053] When the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor is less than the first threshold, the refrigerator determines that the state information of the first temperature sensor is normal.

[0054] When the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor is greater than or equal to the first threshold, the refrigerator determines that the state information of the first temperature sensor is faulty.

[0055] In this solution, the first threshold is 0.7°C. In this way, when the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor is less than 0.7°C, the refrigerator determines that the status information of the first temperature sensor is normal. When the difference between the temperature value collected by the first temperature sensor and the temperature value collected by the second temperature sensor is greater than or equal to 0.7°C, the refrigerator determines that the status information of the first temperature sensor is faulty. With this solution, when the first temperature sensor and the second temperature sensor meet the compressor startup conditions, the status information of the first temperature sensor can be judged in combination with the fluctuation of the temperature data collected by multiple temperature sensors arranged at adjacent positions, thereby ensuring the accuracy of the status information of the first temperature sensor.

[0056] Figure 4 is another schematic diagram of a method for determining status information provided by an embodiment of the present disclosure; Figure 4 As shown, optionally, in S11, the refrigerator determines the state information of the first temperature sensor according to the temperature values ​​collected by the first temperature sensor and the second temperature sensor, including:

[0057] S41, when the first temperature sensor and the second temperature sensor meet the compressor shutdown condition, the refrigerator calculates the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor.

[0058] S42, the refrigerator determines the state information of the first temperature sensor according to the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor.

[0059] In this solution, the refrigerator can determine whether the first temperature sensor and the second temperature sensor meet the compressor shutdown condition in the following way: the refrigerator obtains the shutdown point temperature of the compressor; when the temperature values ​​collected by the first temperature sensor and the second temperature sensor reach the compressor shutdown point temperature, it is determined that the first temperature sensor and the second temperature sensor meet the compressor shutdown condition. As an example, the shutdown point temperature of the compressor in the refrigerator freezer compartment is -19°C. In this way, it is possible to accurately determine whether the first temperature sensor and the second temperature sensor meet the compressor shutdown condition.

[0060] Furthermore, when the first temperature sensor and the second temperature sensor meet the compressor shutdown condition, the current temperature values ​​collected by the first temperature sensor and the second temperature sensor are respectively obtained, and the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor is calculated. Furthermore, after obtaining the difference, the refrigerator can determine the status information of the first temperature sensor in combination with the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor. In this way, the status information of the first temperature sensor can be judged in combination with the fluctuation of the temperature data of the compressor shutdown point collected by multiple temperature sensors arranged at adjacent positions, thereby ensuring the accuracy of the status information of the first temperature sensor.

[0061] Optionally, in S42, the refrigerator determines the state information of the first temperature sensor according to the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor, including:

[0062] When the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor is smaller than the second threshold, the refrigerator determines that the state information of the first temperature sensor is normal.

[0063] When the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor is greater than or equal to the second threshold, the refrigerator determines that the state information of the first temperature sensor is faulty.

[0064] In this solution, the second threshold value is 0.4°C. In this way, when the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor is less than 0.4°C, the refrigerator determines that the status information of the first temperature sensor is normal. When the difference between the current temperature value collected by the first temperature sensor and the current temperature value collected by the second temperature sensor is greater than or equal to 0.4°C, the refrigerator determines that the status information of the first temperature sensor is faulty. With this solution, when the first temperature sensor and the second temperature sensor meet the compressor shutdown conditions, the status information of the first temperature sensor can be judged in combination with the fluctuation of the temperature data collected by multiple temperature sensors arranged at adjacent positions, thereby ensuring the accuracy of the status information of the first temperature sensor.

[0065] Optionally, determining whether the first temperature sensor and the second temperature sensor meet the compressor startup condition or the compressor shutdown condition includes:

[0066] The refrigerator obtains its startup count;

[0067] When the number of startup times of the refrigerator is greater than or equal to the first number, it is determined whether the first temperature sensor and the second temperature sensor meet the compressor startup condition or the compressor shutdown condition.

[0068] In this way, the timing of executing the judgment process is accurately determined, meeting the user's demand for precise control of the refrigerator.

[0069] Optionally, after controlling the refrigerator compressor to execute the target control scheme, the method further includes:

[0070] The refrigerator accumulates the number of starts of the refrigerator compressor that it stores.

[0071] In this way, the user can know the number of times the refrigerator compressor is started at any time, thereby ensuring the validity of data records.

[0072] Optionally, when it is determined that the status information of the first temperature sensor is faulty, the refrigerator uploads the fault data of the first temperature sensor to the main control board.

[0073] In this solution, when it is determined that the status information of the first temperature sensor is a fault, the refrigerator can upload the fault data of the first temperature sensor to the main control board. In this way, it is convenient to accurately upload the fault data of the first temperature sensor, which helps users to query the fault data.
