Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0048] The embodiment of the present application provides a refrigerator and its control method, control device, and storage medium to solve the problem that the refrigeration effect of the existing refrigerator in the quick-freezing mode is affected by the ambient temperature and may cause problems such as failure to reach the temperature and stop, or over-refrigeration. The following will be described in conjunction with the accompanying drawings.

[0049] For the control method of the refrigerator provided by the embodiment of the present application, please refer to Figure 1 , the method includes the following steps:

[0050] Step S101: In response to the quick-freezing mode control instruction, obtain the ambient temperature;

[0051] Step S102: Determine the target quick-freezing temperature of the freezing compartment and the target gear of the refrigerator according to the ambient temperature;

[0052] Step S103: Control the refrigerator to operate based on the target gear until the freezing compartment reaches the target quick-freezing temperature; wherein, the ambient temperature is positively correlated with the target quick-freezing temperature, and the ambient temperature is negatively correlated with the target gear.

[0053] For the control method of the refrigerator provided by the embodiments of the present application, when the refrigerator turns on the quick-freezing mode, the specific target gear and the final target quick-freezing temperature are determined according to the ambient temperature of the refrigerator. Among them, the ambient temperature is positively correlated with the target quick-freezing temperature, and the ambient temperature is negatively correlated with the target gear. That is, the higher the ambient temperature, the higher the target quick-freezing temperature corresponding to the quick-freezing mode, and the lower the target gear for the refrigerator to operate; the lower the ambient temperature, the lower the target quick-freezing temperature corresponding to the quick-freezing mode, and the higher the target gear for the refrigerator to operate. A flexible quick-freezing refrigeration strategy is provided according to the ambient temperature of the refrigerator, avoiding problems such as the refrigerator being unable to reach the temperature and shutting down or over-cooling due to the fixed quick-freezing temperature being affected by the ambient temperature.

[0054] It can be understood that the ambient temperature of the refrigerator is the temperature around the placement position of the refrigerator.

[0055] Optionally, after the freezing compartment reaches the target quick-freezing temperature, the method further includes: controlling the refrigerator to shut down. That is, after the freezing compartment of the refrigerator reaches the target quick-freezing temperature, it indicates that the refrigerator has completed the refrigeration of this quick-freezing mode, so the refrigeration is ended by shutting down.

[0056] Optionally, in step S102, determining the target quick-freezing temperature and the target gear of the freezing compartment according to the ambient temperature includes: if the ambient temperature is greater than or equal to the first ambient temperature, such as 30°C, then determine the target quick-freezing temperature of the freezing compartment as the first preset temperature, such as -24°C, and the target gear of the refrigerator as the first gear; if the ambient temperature is less than the first ambient temperature and greater than the second ambient temperature, such as less than 30°C and greater than 15°C, then determine the target quick-freezing temperature of the freezing compartment as the second preset temperature, such as -32°C, and the target gear of the refrigerator as the second gear; if the ambient temperature is less than or equal to the second ambient temperature, such as 15°C, then determine the target quick-freezing temperature of the freezing compartment as the third preset temperature, such as -40°C, and the target gear of the refrigerator as the third gear; wherein, the first ambient temperature is higher than the second ambient temperature, the first preset temperature, the second preset temperature, and the third preset temperature decrease in sequence, and the first gear, the second gear, and the third gear increase in sequence.

[0057] It can be understood that the first gear, the second gear, and the third gear respectively correspond to a set of operating powers of the compressor and the blower. Among them, the operating powers of the compressor and the blower corresponding to the first gear are relatively small, the operating powers of the compressor and the blower corresponding to the second gear are greater than those of the compressor and the blower corresponding to the first gear, and the operating powers of the compressor and the blower corresponding to the third gear are greater than those of the compressor and the blower corresponding to the second gear. In some examples, the operating powers of the compressor and the blower corresponding to the third gear can be the maximum operating power of the compressor and the maximum operating power of the blower respectively.

[0058] When the ambient temperature is relatively high, the heat dissipation efficiency of the refrigerator decreases, and the compressor needs to run for a longer time to reach an extremely low temperature (such as -24°C). Therefore, by moderately increasing the target quick-freezing temperature of the freezer compartment at this time (such as adjusting from -24°C to -18°C), the compressor load can be significantly reduced, energy consumption can be reduced, and the risk of the compressor overheating and shutting down can be avoided. For example, when the ambient temperature is 40°C, forcibly maintaining -24°C may cause the compressor to run at a high load continuously, while after adjusting to -18°C, the running time is shortened, which is more energy-efficient and prolongs the service life. When the ambient temperature is relatively low (such as below 10°C in winter), the heat dissipation efficiency of the refrigerator is high, and the compressor can more easily reach a lower target quick-freezing temperature. At this time, reducing the target quick-freezing temperature, such as from -18°C to -20°C, can utilize the environmental advantage to enhance the freezing capacity of the freezer compartment and provide a more suitable storage environment for foods that need deep freezing.

[0059] Therefore, by setting the target quick-freezing temperature to be higher when the ambient temperature is higher and lower when the ambient temperature is lower, the balance among energy consumption, performance, and service life of the refrigerator is achieved, which not only meets the basic freezing needs of users but also avoids the system risks of the refrigerator under extreme working conditions.

[0060] Optionally, step S103 controls the operation of the refrigerator based on the target gear, including: reducing the first preset gear based on the target gear and obtaining the reduced gear, controlling the operation of the refrigerator for a first preset duration (such as 10 minutes) according to the reduced gear; obtaining the temperature difference between the temperature of the freezer compartment and the target quick-freezing temperature; and adjusting the operation gear of the refrigerator according to the temperature difference.

[0061] The quick-freezing mode of the refrigerator is divided into two control stages. In the first stage, according to the gear after reducing the first preset gear based on the target gear, the refrigerator is controlled to operate at a reduced gear for the first preset duration, so as to reduce the noise when the refrigerator starts to operate, leaving sufficient time for the user to stay away from the refrigerator. This prevents the refrigerator from immediately operating at a high gear after the user just turns on the quick-freezing mode, resulting in a large amount of noise and a poor user experience. After the refrigerator operates at a reduced gear for the first preset duration, usually the user has left the vicinity of the refrigerator. At this time, according to the temperature difference between the freezing compartment and the target quick-freezing temperature, the operating gear of the refrigerator is adjusted, so that the operating gear of the refrigerator better matches the current temperature difference, improving the temperature adjustment accuracy, realizing the dynamic adjustment of the refrigerator gear according to the real-time temperature, and enhancing the intelligence of refrigerator control.

[0062] Optionally, adjusting the operating gear of the refrigerator according to the temperature difference includes: if the temperature difference is greater than or equal to the first preset temperature difference, such as 5°C, the refrigerator is controlled to operate according to the target gear; if the temperature difference is less than the first preset temperature difference and greater than the second preset temperature difference, such as less than 5°C and greater than 2°C, the refrigerator is controlled to operate according to the gear after reducing the second preset gear from the target gear; if the temperature difference is less than or equal to the second preset temperature difference, such as 2°C, the current gear is maintained; where the first preset temperature difference is higher than the second preset temperature difference; the second preset gear is less than the first preset gear. In some examples, the first preset gear can be the second gear, and the second preset gear is the first gear.

[0063] For example, if the temperature difference is greater than or equal to 5°C, the refrigerator is controlled to operate according to the target gear (that is, the current gear is increased by two gears); if the temperature difference is less than 5°C and greater than 2°C, the refrigerator is controlled to operate according to the gear after reducing one gear from the target gear; if the temperature difference is less than or equal to 2°C, the current gear is maintained.

[0064] Adjusting the operating gear of the refrigerator according to the temperature difference between the freezing compartment and the target quick-freezing temperature not only meets the refrigeration requirements but also reduces the energy consumption of the refrigerator.

[0065] Optionally, adjusting the operating gear of the refrigerator according to the temperature difference further includes: if the temperature difference is less than or equal to the third preset temperature difference, such as 1°C, the refrigerator is controlled to operate according to the fourth gear; where the third preset temperature difference is less than the second preset temperature difference. The fourth gear is lower than the first gear, and the operating power of the compressor and the blower corresponding to the fourth gear is less than the operating power of the compressor and the blower corresponding to the first gear. In some examples, the operating power of the compressor and the blower corresponding to the fourth gear can be the minimum operating power of the compressor and the minimum operating power of the blower respectively.

[0066] That is, when the temperature difference between the freezing temperature and the target quick-freezing temperature is small and within the range of 1°C, the refrigerator can be controlled to operate with the minimum power, reducing energy consumption.

[0067] Optionally, obtaining the temperature difference between the temperature of the freezing compartment and the target quick-freezing temperature includes: obtaining the temperature difference between the temperature of the freezing compartment and the target quick-freezing temperature every second preset duration, such as every five minutes.

[0068] That is, the temperature difference between the temperature of the freezing compartment and the target quick-freezing temperature can be obtained every 5 minutes, and the operating gear of the refrigerator can be dynamically adjusted according to the temperature difference, so that the operating gear of the refrigerator better matches the current temperature difference.

[0069] Optionally, after controlling the operation of the refrigerator according to the reduced gear, the method further includes: obtaining the noise situation around the refrigerator; determining a duration correction coefficient according to the noise situation; and correcting the first preset duration according to the duration correction coefficient.

[0070] That is, the first preset duration is not necessarily a fixed value and can be dynamically adjusted according to the noise situation around the refrigerator. Generally, the noise situation around the refrigerator can reflect the user's activity situation. When the user is moving around the refrigerator, the noise is relatively large, and when the user moves away from the refrigerator, the noise around the refrigerator is relatively small. For example, when the noise around the refrigerator is small for a certain period of time, the correction coefficient can be small, that is, the first preset duration is shortened; when the noise around the refrigerator is large for a certain period of time, the correction coefficient can be large, that is, the first preset duration is extended, so as to reserve sufficient activity time for the user, reduce the working noise of the refrigerator when the user is around the refrigerator, and improve the user experience.

Please refer to Figure 2 , the device includes a temperature acquisition module 1, an analysis module 2, and a control module 3.
