Description

Technical Field

[0001] This application belongs to the field of smart home appliance technology, and in particular relates to a control method, device, storage medium and refrigerator for a refrigerator. Background Technology

[0002] Currently, refrigerators do not have temperature sensors in the freezer compartment. The refrigerator can only control the compressor to start and stop through the temperature sensor in the refrigerator compartment. However, in low ambient temperatures, the temperature in the refrigerator compartment is always below the compressor's start-up temperature, causing the compressor to fail to start.

[0003] In related technologies, a temperature compensation heater capable of operating at low ambient temperatures is installed in the refrigerator compartment. This heater raises the temperature of the refrigerator compartment to above the compressor's start-up temperature, thus activating the compressor and enabling the refrigerator to cool. However, adding a temperature compensation heater to the refrigerator compartment increases the cost of the refrigerator. Furthermore, the energy consumed by the temperature compensation heater not only fails to improve the refrigerator's cooling effect but also cancels out the cold air inside the refrigerator, increasing its power consumption.

[0043] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0044] Currently, frost-free refrigerators have a freezer compartment and a refrigerator compartment, which can share a single compressor and fan. No temperature sensor is installed in the freezer compartment; instead, a temperature sensor located in the refrigerator compartment controls the compressor and fan's operation. This method works normally in non-low ambient temperatures. However, low ambient temperatures will affect the refrigerator compartment temperature, keeping it consistently below the compressor's operating temperature. This can prevent the compressor from starting properly, thus hindering the refrigerator's cooling function.

[0045] In related technologies, a temperature compensation heater capable of operating at low ambient temperatures is installed in the refrigerator compartment. This heater raises the temperature of the refrigerator compartment to above the compressor's start-up temperature, enabling the compressor to start and perform the refrigerator's cooling function. However, adding a temperature compensation heater to the refrigerator compartment increases the refrigerator's cost. Furthermore, the energy consumed by the heater not only fails to improve the cooling effect but also cancels out the cold air inside the refrigerator, increasing power consumption. Additionally, even with a temperature compensation heater, the refrigerator compartment temperature may not reach the compressor's start-up temperature, preventing the refrigerator from cooling.

[0046] To address the aforementioned problems, embodiments of this application provide a refrigerator control method, a refrigerator control device, a storage medium, and a refrigerator. Please refer to... Figure 1 , Figure 1 This is a schematic flowchart of the first embodiment of the refrigerator control method provided in this application. The refrigerator can be a frost-free refrigerator, such as a dual-cycle frost-free refrigerator or a triple-cycle frost-free refrigerator. The specific flow of the refrigerator control method can be as follows:

[0047] 101. Obtain the first refrigeration temperature corresponding to the refrigeration compartment and the first freezing temperature corresponding to the freezer compartment.

[0048] It should be noted that the temperature of the refrigerator compartment affects the compressor's start and stop, while the ambient temperature affects the refrigerator compartment temperature, causing the refrigerator compartment temperature to fall below the compressor's start-up temperature. Therefore, to control the compressor's start and stop, the current ambient temperature must first be obtained.

[0049] If the current ambient temperature is greater than or equal to the preset ambient temperature, the first refrigeration temperature corresponding to the refrigerator compartment is obtained. If the first refrigeration temperature is greater than or equal to the refrigerator start-up temperature, the refrigerator compressor is controlled to operate at a first speed. If the first refrigeration temperature is less than or equal to the refrigerator stop-off temperature, the compressor is controlled to stop operating. Note that the refrigerator's cooling function is required because the refrigerator compartment temperature is relatively high, causing the temperature of the refrigerator compartment to decrease; therefore, the refrigerator start-up temperature is greater than the refrigerator stop-off temperature. The temperature of the refrigerator compartment, such as the first refrigeration temperature, can be detected by a first temperature sensor installed in the refrigerator compartment.

[0050] Specifically, if the current ambient temperature is greater than or equal to the preset ambient temperature, where the preset ambient temperature will not lower the temperature of the refrigerator compartment, and the current ambient temperature is greater than or equal to the preset ambient temperature, the temperature of the refrigerator compartment will rise even when the compressor is not working. This allows the first refrigerator temperature to reach the compressor's refrigerator start-up temperature, meaning the first refrigerator temperature is greater than or equal to the refrigerator start-up temperature, thus allowing control over the compressor's start and stop. Conversely, if the first refrigerator temperature is less than or equal to the refrigerator stop temperature, it means the refrigerator compartment no longer needs refrigeration through the compressor, and therefore the compressor can be stopped.

[0051] The preset ambient temperature can be a fixed value or a range, such as 8℃ or 10℃, or 8-10℃. The refrigeration start-up temperature and refrigeration stop-off temperature are mappings between the refrigeration compartment and the compressor. When the first refrigeration temperature of the refrigeration compartment is greater than or equal to the refrigeration start-up temperature, the compressor can be controlled to run at its first speed; when the first refrigeration temperature of the refrigeration compartment is less than or equal to the refrigeration stop-off temperature, the compressor can be controlled to stop running. The refrigeration start-up temperature and refrigeration stop-off temperature can be set according to the compressor's power, model, and user needs; no specific limitations are specified here.

[0052] After obtaining the current ambient temperature, if the current ambient temperature is lower than the preset ambient temperature, it indicates that the current ambient temperature is in a low ambient temperature state. The low ambient temperature will affect the temperature of the refrigerator compartment, that is, lower the temperature of the refrigerator compartment or prevent the temperature of the refrigerator compartment from rising when the compressor is not working. As a result, the first refrigeration temperature of the refrigerator compartment cannot reach the compressor's refrigeration start-up temperature, that is, the first refrigeration temperature is lower than the refrigeration start-up temperature, and thus the compressor cannot be controlled to start and stop. Since the refrigerator compartment and the freezer compartment share a compressor, if the compressor cannot operate normally, the freezer compartment will never be in a cooling state. Since the food stored in the freezer compartment usually needs to be kept at a lower temperature to be preserved, it will cause the food in the refrigerator compartment to spoil.

[0053] Understandably, if the compressor's operation is controlled solely by the refrigerator compartment's temperature, it will malfunction if the ambient temperature is lower than the preset temperature (i.e., a low ambient temperature). Typically, the freezer compartment doesn't have a temperature sensor for controlling the compressor's operation; however, it does have an evaporator that frosts over during prolonged cooling. Therefore, the freezer compartment includes a defrost mode. During defrosting, the freezer compartment's temperature needs to be monitored in real-time. Therefore, a temperature sensor is required in the freezer compartment to monitor the temperature and control the duration of the defrost mode based on the temperature detected by the sensor.

[0054] In other words, a temperature sensor is installed in the freezer compartment to detect the temperature during the defrosting process. Therefore, this temperature sensor can be reused to control the compressor's start and stop. The freezer compartment temperature sensor can serve as a secondary temperature sensor. It should be noted that since the freezer compartment temperature sensor can only operate in one mode, when the current ambient temperature is lower than the preset ambient temperature, it is necessary to obtain the freezer compartment's operating mode. The freezer compartment's operating modes include defrosting mode and control mode. If the freezer compartment is in defrosting mode, the secondary temperature sensor needs to detect the freezer compartment temperature during defrosting mode, and the defrosting duration is controlled based on the temperature detected by the secondary temperature sensor.

[0055] Correspondingly, if the freezer compartment is in control mode, the compressor's start and stop can be controlled via the second temperature sensor. Specifically, the second temperature sensor obtains the first freezing temperature corresponding to the freezer compartment. Note that the freezer compartment's defrost mode and control mode cannot operate simultaneously; that is, the second temperature sensor cannot work in both defrost and control modes at the same time.

[0056] In addition, even at low ambient temperatures, i.e. when the current ambient temperature is lower than the preset ambient temperature, the temperature of the cold storage compartment can still control the start and stop of the compressor. Therefore, the first cold storage temperature can be obtained through the first temperature sensor.

[0057] 102. If the first refrigeration temperature is greater than or equal to the refrigeration start-up temperature and / or the first freezing temperature is greater than or equal to the freezing start-up temperature, then control the refrigerator compressor to operate at the first speed.

[0058] After obtaining the first refrigeration temperature corresponding to the refrigerator compartment through the first temperature sensor, if the first refrigeration temperature is greater than or equal to the refrigerator start-up temperature, the refrigerator compressor is controlled to run at the first speed. At this time, the set refrigerator start-up temperature of the compressor is the same as or not much different from the current ambient temperature, so it is possible for the freezer compartment to control the compressor's start and stop at a low ambient temperature. However, if the refrigerator start-up temperature is much higher than the current ambient temperature, it is impossible to control the compressor's start and stop at a low ambient temperature by using the first refrigeration temperature of the refrigerator compartment.

[0059] Correspondingly, if the first freezing temperature corresponding to the freezer compartment obtained by the second temperature sensor is greater than or equal to the freezer start-up temperature, the refrigerator compressor can be controlled to operate at the first speed. Since the temperature inside the freezer compartment is much lower than the current ambient temperature, it is not affected by the low ambient temperature. Therefore, under high ambient temperature conditions, i.e., when the current ambient temperature is greater than or equal to the preset ambient temperature, the compressor's start and stop can be controlled by the first refrigeration temperature corresponding to the refrigerator compartment and / or the first freezing temperature corresponding to the freezer compartment. Under low ambient temperature conditions, except in special cases, such as when the current ambient temperature is the same as the refrigeration start-up temperature, the compressor's start and stop can be controlled by the first freezing temperature corresponding to the freezer compartment. Since the first freezing temperature is multiplexed by the second temperature sensor (defrost mode and control mode), the refrigerator can achieve cooling function in all environments without adding additional components.

[0060] Furthermore, after the refrigerator compressor starts operating at its first speed, if the first refrigeration temperature is greater than or equal to the fan's refrigeration start-up temperature, the fan will operate at its second speed; if the first refrigeration temperature is less than the fan's refrigeration stop-off temperature, the fan will stop operating. The fan's refrigeration start-up temperature and refrigeration stop-off temperature represent a mapping relationship between the refrigerator compartment and the fan. These temperatures can be set according to the fan's power, model, and user needs, and are not specifically limited here. The fan's refrigeration start-up temperature can be lower than the compressor's corresponding refrigeration start-up temperature, and the fan's refrigeration stop-off temperature can be the same as the compressor's corresponding refrigeration stop-off temperature.

[0061] 103. If the first refrigeration temperature is less than or equal to the refrigeration shutdown temperature and the first freezing temperature is less than or equal to the freezing shutdown temperature, then control the compressor to stop operating.

[0062] If the first refrigeration temperature is less than or equal to the refrigeration shutdown temperature, and the first freezing temperature is less than or equal to the freezing shutdown temperature, then the compressor will be stopped. Specifically, stopping the compressor requires both the first refrigeration temperature and the first freezing temperature to be less than or equal to the freezing shutdown temperature simultaneously.

[0063] The refrigeration start-up temperature and refrigeration stop-down temperature are mapping relationships between the refrigeration compartment and the compressor. Specifically, when the first freezing temperature of the refrigeration compartment is greater than or equal to the refrigeration start-up temperature, the compressor can be controlled to operate at its first speed; when the first freezing temperature of the refrigeration compartment is less than or equal to the refrigeration stop-down temperature, the compressor can be controlled to stop operating. The refrigeration start-up temperature and refrigeration stop-down temperature can be set according to the compressor's power, model, and user requirements; no specific limitations are specified here.

[0064] When the first refrigeration temperature is less than or equal to the refrigeration shutdown temperature, and the first freezing temperature is less than or equal to the freezing shutdown temperature, the compressor and fan can be stopped simultaneously. Specifically, the compressor's refrigeration shutdown temperature is the same as the fan's refrigeration shutdown temperature, and the compressor's freezing shutdown temperature is the same as the fan's freezing shutdown temperature.

[0065] As can be seen from the above, this embodiment obtains the first refrigeration temperature corresponding to the refrigeration compartment and the first freezing temperature corresponding to the freezer compartment. If the first refrigeration temperature is greater than or equal to the refrigeration start-up temperature and / or the first freezing temperature is greater than or equal to the freezer start-up temperature, the refrigerator compressor is controlled to operate at a first speed. If the first refrigeration temperature is less than or equal to the refrigeration stop-off temperature and the first freezing temperature is less than or equal to the freezer stop-off temperature, the compressor is controlled to stop operating. By controlling the logical relationship between the temperatures of the refrigeration and freezer compartments and the start-up and stop-off temperatures of the compressor in different compartments, and by reusing the second temperature sensor in the freezer compartment, the compressor start-up and stop-off control is achieved without adding any components, reducing cost and power consumption.

[0066] Please see Figure 2 , Figure 2 This is a second flowchart illustrating the refrigerator control method provided in this application. The specific operation steps of the refrigerator control method are as follows:

[0067] 201, Get the current ambient temperature.

[0068] In this embodiment, it should be noted that the temperature of the refrigerator compartment affects the compressor's start-up and shutdown, while the ambient temperature affects the refrigerator compartment temperature, causing the refrigerator compartment temperature to fall below the compressor's start-up temperature. Therefore, to achieve compressor start-up and shutdown control, the current ambient temperature needs to be obtained first.

[0069] If the current ambient temperature is greater than or equal to the preset ambient temperature, the first refrigeration temperature corresponding to the refrigerator compartment is obtained. If the first refrigeration temperature is greater than or equal to the refrigerator start-up temperature, the refrigerator compressor is controlled to operate at a first speed. If the first refrigeration temperature is less than or equal to the refrigerator stop-off temperature, the compressor is controlled to stop operating. Note that the refrigerator's cooling function is required because the refrigerator compartment temperature is relatively high, causing the temperature of the refrigerator compartment to decrease; therefore, the refrigerator start-up temperature is greater than the refrigerator stop-off temperature. The temperature of the refrigerator compartment, such as the first refrigeration temperature, can be detected by a first temperature sensor installed in the refrigerator compartment.

[0070] Specifically, if the current ambient temperature is greater than or equal to the preset ambient temperature, where the preset ambient temperature will not lower the temperature of the refrigerator compartment, and the current ambient temperature is greater than or equal to the preset ambient temperature, the temperature of the refrigerator compartment will rise even when the compressor is not working. This allows the first refrigerator temperature to reach the compressor's refrigerator start-up temperature, meaning the first refrigerator temperature is greater than or equal to the refrigerator start-up temperature, thus allowing control over the compressor's start and stop. Conversely, if the first refrigerator temperature is less than or equal to the refrigerator stop temperature, it means the refrigerator compartment no longer needs refrigeration through the compressor, and therefore the compressor can be stopped.

[0071] The preset ambient temperature can be a fixed value or a range, such as a preset ambient temperature of 8℃ or 10℃, or a preset ambient temperature of 8-10℃. The refrigeration start-up temperature and refrigeration stop-down temperature are mapping relationships between the refrigeration compartment and the compressor. The refrigeration start-up temperature and refrigeration stop-down temperature can be set according to the compressor's power, model, and user needs, and are not specifically limited here.

[0072] 202. If the current ambient temperature is lower than the preset ambient temperature and the working mode of the freezer compartment is in control mode, then obtain the first refrigeration temperature corresponding to the refrigerator compartment and the first freezing temperature corresponding to the freezer compartment.

[0073] If the current ambient temperature is lower than the preset ambient temperature, it means that the current ambient temperature is in a low ambient temperature state. The low ambient temperature will affect the temperature of the refrigerator compartment, that is, lower the temperature of the refrigerator compartment or prevent the temperature of the refrigerator compartment from rising when the compressor is not working. As a result, the first refrigeration temperature of the refrigerator compartment cannot reach the compressor's refrigeration start-up temperature. That is, the first refrigeration temperature is lower than the refrigeration start-up temperature, and thus the compressor cannot be controlled to start and stop. Since the refrigerator compartment and the freezer compartment share a compressor, if the compressor cannot operate normally, the freezer compartment will never be in a cooling state. Since the food stored in the freezer compartment usually needs to be kept at a lower temperature to be preserved, it will cause the food in the refrigerator compartment to spoil.

[0074] Because the freezer compartment is equipped with a temperature sensor that detects the freezer compartment temperature during the defrosting process, this temperature sensor can be reused to control the compressor's start and stop. The freezer compartment temperature sensor can serve as a secondary temperature sensor. It should be noted that since the freezer compartment temperature sensor can only operate in one mode, when the current ambient temperature is lower than the preset ambient temperature, it is necessary to obtain the freezer compartment's operating mode. The freezer compartment's operating modes include defrosting mode and control mode. If the freezer compartment is in defrosting mode, the secondary temperature sensor needs to detect the freezer compartment temperature during defrosting mode, and the defrosting duration is controlled based on the temperature detected by the secondary temperature sensor.

[0075] Correspondingly, if the freezer compartment is in control mode, the compressor's start and stop can be controlled via the second temperature sensor. Specifically, the second temperature sensor obtains the first freezing temperature corresponding to the freezer compartment. Note that the freezer compartment's defrost mode and control mode cannot operate simultaneously; that is, the second temperature sensor cannot work in both defrost and control modes at the same time.

[0076] In addition, even at low ambient temperatures, i.e. when the current ambient temperature is lower than the preset ambient temperature, the temperature of the cold storage compartment can still control the start and stop of the compressor. Therefore, the first cold storage temperature can be obtained through the first temperature sensor.

[0077] 203. If the first refrigeration temperature is greater than or equal to the refrigeration start-up temperature and / or the first freezing temperature is greater than or equal to the freezing start-up temperature, then control the refrigerator compressor to operate at the first speed.

[0078] If the first refrigeration temperature is greater than or equal to the refrigeration start-up temperature, the refrigerator compressor is controlled to run at the first speed. At this time, the set refrigeration start-up temperature of the compressor is the same as or not much different from the current ambient temperature, so it is possible for the freezer compartment to control the compressor's start and stop at a low ambient temperature. However, if the refrigeration start-up temperature is much higher than the current ambient temperature, it is not possible to control the compressor's start and stop at a low ambient temperature by using the first refrigeration temperature of the refrigerator compartment.

[0079] Correspondingly, if the first freezing temperature corresponding to the freezer compartment is greater than or equal to the freezer start-up temperature, the refrigerator compressor can be controlled to operate at the first speed. Since the temperature inside the freezer compartment is much lower than the current ambient temperature, it is not affected by the low ambient temperature. Therefore, under high ambient temperature conditions, i.e., when the current ambient temperature is greater than or equal to the preset ambient temperature, the compressor's start and stop are controlled by the first refrigeration temperature corresponding to the refrigerator compartment and / or the first freezing temperature corresponding to the freezer compartment. Under low ambient temperature conditions, except in special cases, such as when the current ambient temperature is the same as the refrigeration start-up temperature, the compressor's start and stop can be controlled by the first freezing temperature corresponding to the freezer compartment. Since the first freezing temperature is multiplexed through the second temperature sensor (defrost mode and control mode), the refrigerator can achieve cooling function in all environments without adding additional components.

[0080] 204. If the first refrigeration temperature is greater than or equal to the refrigeration start-up temperature corresponding to the fan, then control the refrigerator fan to operate at the second speed.

[0081] After the refrigerator compressor starts operating at a first speed, if the first refrigeration temperature is greater than or equal to the fan's refrigeration start-up temperature, the fan is controlled to operate at a second speed; if the first refrigeration temperature is less than the fan's refrigeration stop-off temperature, the fan is controlled to stop operating. The fan's refrigeration start-up temperature and refrigeration stop-off temperature represent a mapping relationship between the refrigerator compartment and the fan. These temperatures can be set according to the fan's power, model, and user needs, and are not specifically limited here. The fan's refrigeration start-up temperature can be lower than the compressor's corresponding refrigeration start-up temperature, and the fan's refrigeration stop-off temperature can be the same as the compressor's corresponding refrigeration stop-off temperature.

[0082] 205. Obtain the second refrigeration temperature corresponding to the refrigeration compartment and the second freezing temperature corresponding to the freezer compartment.

[0083] It should be noted that for a fixed-frequency refrigerator with a fixed-frequency compressor and fixed-frequency fan, if the first refrigeration temperature is less than or equal to the refrigeration stop temperature, and the first freezing temperature is less than or equal to the freezing stop temperature, the compressor will stop operating. However, because the compressor maintains a fixed-frequency operation, this process results in a relatively long compressor running time. To solve this problem, a variable-frequency compressor and a variable-frequency refrigerator can be used to shorten the compressor's running time.

[0084] Understandably, during operation, the compressor and fan blow cold air into the refrigerator and freezer compartments in equal proportions—half of the cold air goes to the refrigerator compartment and half to the freezer compartment. Since the refrigerator compartment requires a higher temperature than the freezer compartment, the refrigerator compartment reaches the compressor and fan's shut-off temperature in less time than the freezer compartment. If the fan consistently blows cold air into both compartments in the same proportion, the refrigerator compartment temperature will be significantly lower than the compressor and fan's shut-off temperature, while the freezer compartment temperature will not yet reach it. This excessively low refrigerator compartment temperature not only wastes cold air but also causes excessive moisture loss from stored food, hindering its preservation.

[0085] Therefore, the operating speed of the compressor and refrigerator can be controlled by variable frequency compressors and refrigerators, and the air supply ratio of the fan to the refrigerator compartment and freezer compartment can be adjusted to improve the working efficiency of the compressor and refrigerator and reduce the running time of the compressor and fan.

[0086] 206. If the second refrigeration temperature is less than or equal to the refrigeration shutdown temperature, and the second freezing temperature is greater than the freezing shutdown temperature but less than the preset freezing temperature, then control the compressor to run at the third speed and control the fan to run at the fourth speed.

[0087] Specifically, the second refrigeration temperature corresponding to the refrigeration compartment and the second freezing temperature corresponding to the freezer compartment are obtained. If the second refrigeration temperature is less than or equal to the refrigeration shutdown temperature, it means that the second refrigeration temperature of the refrigeration compartment has reached the refrigeration shutdown temperature, and the refrigeration compartment does not need to continue cooling. At this time, if the second freezing temperature is greater than the freezing shutdown temperature but less than the preset freezing temperature, the air supply ratio of the fan to the refrigeration and freezer compartments can be adjusted. Specifically, all the cold air can be blown into the freezer compartment by the fan, while the freezer compartment does not need to continue cooling and therefore does not need the fan to blow cold air.

[0088] It should be noted that since the refrigerator compartment does not require a fan to blow cold air, the range of air blown by the fan can be halved. Therefore, it is not necessary to run the fan at an excessively high speed to blow all the cold air into the freezer compartment. Thus, the fan speed can be reduced, that is, the fan speed can be adjusted from the second speed to the fourth speed, where the fourth speed is less than the second speed. For example, the second speed is 3000 rpm and the fourth speed is 2000 rpm.

[0089] To reduce compressor operating time, the compressor speed can be increased, that is, the compressor speed can be adjusted from the first speed to the third speed, where the first speed is less than the third speed, for example, the first speed is 3000 rpm and the third speed is 4500 rpm.

[0090] Specifically, if the second refrigeration temperature is less than or equal to the refrigeration shutdown temperature, and the second freezing temperature is greater than the freezing shutdown temperature but less than the preset freezing temperature, then the compressor is controlled to operate at a third speed, and the fan is controlled to operate at a fourth speed. Here, the preset freezing temperature is greater than the freezing shutdown temperature but less than the freezing start temperature. Since the compressor and fan speeds are adjusted only after the refrigeration compartment temperature reaches the refrigeration shutdown temperature, the freezing compartment temperature is lower than the freezing start temperature; that is, the preset freezing temperature is less than the freezing start temperature.

[0091] 207. If the second refrigeration temperature is less than or equal to the refrigeration shutdown temperature, and the second freezing temperature is less than or equal to the freezing shutdown temperature, then control the compressor and fan to stop operating.

[0092] When the compressor is running at the third speed and the fan is running at the fourth speed, if the second refrigeration temperature is less than or equal to the refrigeration shutdown temperature and the second freezing temperature is less than or equal to the freezing shutdown temperature, then the compressor and fan will be stopped. Specifically, the compressor's refrigeration shutdown temperature is the same as the fan's refrigeration shutdown temperature, and the compressor's freezing shutdown temperature is the same as the fan's freezing shutdown temperature.

[0093] As can be seen from the above, in this embodiment, by acquiring the current ambient temperature, if the current ambient temperature is lower than the preset ambient temperature and the freezer compartment is in control mode, the first refrigeration temperature corresponding to the refrigerator compartment and the first freezing temperature corresponding to the freezer compartment are acquired. If the first refrigeration temperature is greater than or equal to the refrigerator start-up temperature and / or the first freezing temperature is greater than or equal to the freezer start-up temperature, the refrigerator compressor is controlled to run at a first speed. If the first refrigeration temperature is greater than or equal to the refrigerator start-up temperature corresponding to the fan, the refrigerator fan is controlled to run at a second speed. The second refrigeration temperature corresponding to the refrigerator compartment and the second freezing temperature corresponding to the freezer compartment are acquired. If the second refrigeration temperature is less than or equal to the refrigerator stop-off temperature and the second freezing temperature is greater than the freezer stop-off temperature and less than the preset freezing temperature, the compressor is controlled to run at a third speed and the fan is controlled to run at a fourth speed. If the second refrigeration temperature is less than or equal to the refrigerator stop-off temperature and the second freezing temperature is less than or equal to the freezer stop-off temperature, the compressor and the fan are controlled to stop running. By controlling the logical relationship between the temperature of the refrigerator and freezer compartments and the start-up and shutdown temperatures of the compressor in different compartments, the compressor's start-up and shutdown can be controlled without adding extra components, thus reducing costs and power consumption.

[0094] In addition, when the second refrigeration temperature in the refrigeration compartment reaches the refrigeration shutdown temperature, the speed of the compressor and fan can be adjusted, as well as the air delivery ratio of the fan to the refrigeration and freezer compartments. This can shorten the running time of the compressor and fan and further reduce the power consumption of the refrigerator.

[0106] If the first refrigeration temperature is less than or equal to the refrigeration shutdown temperature, the compressor will be stopped.

[0107] In some embodiments, the refrigerator control device 300 may further include a fan control module, which may be used for:

[0110] Obtain the second refrigeration temperature corresponding to the refrigeration compartment and the second freezing temperature corresponding to the freezer compartment;

[0111] If the second refrigeration temperature is less than or equal to the refrigeration shutdown temperature, and the second freezing temperature is greater than the freezing shutdown temperature but less than the preset freezing temperature, then the compressor is controlled to operate at a third speed, and the fan is controlled to operate at a fourth speed. The preset freezing temperature is greater than the freezing shutdown temperature but less than the freezing start temperature, the third speed is greater than the first speed, and the fourth speed is less than the second speed.

[0112] In some embodiments, the refrigerator control device 300 may further include a fourth control module, which may be used for:

[0113] If the second refrigeration temperature is less than or equal to the refrigeration shutdown temperature, and the second freezing temperature is less than or equal to the freezing shutdown temperature, then the compressor and fan will be stopped.

If the first refrigeration temperature is less than or equal to the refrigeration stop-off temperature and the first freezing temperature is less than or equal to the freezer stop-off temperature, the second control module 303 controls the compressor to stop operating. By controlling the logical relationship between the temperatures of the refrigeration and freezer compartments and the start-up and stop-off temperatures of the compressor in different compartments, the start-up and stop-off control of the compressor is achieved without adding any components, reducing cost and power consumption.
