Therefore, this application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in this application.

[0044] An embodiment of this application provides a control method for a refrigerator, which can be a single-door, double-door, French door, cross-type refrigerator, or other types of refrigerators. Exemplarily, please refer to Figure 1 , Figure 1 which is a flowchart of the control method for the refrigerator provided by the embodiment of this application. The refrigeration system of the refrigerator includes a compressor, a condenser, an anti-condensation pipe, and a switching member. The anti-condensation pipe is connected in parallel to the connecting pipeline between the compressor and the condenser. The switching member is connected to the anti-condensation pipe, and the switching member has a first state in which the refrigerant flows through the anti-condensation pipe and a second state in which the refrigerant stops flowing through the anti-condensation pipe. The control method includes the following steps S101 - step S103:

[0045] Step S101: Obtain the current ambient temperature and ambient humidity;

[0046] It should be noted that the anti-condensation pipe is usually embedded in the easily condensable parts of the refrigerator body, for example, embedded in the freezing port frame of the freezer. The anti-condensation principle of the anti-condensation pipe is to perform heat compensation on the targeted part to reduce the condensation phenomenon.

[0047] In step S101, the ambient temperature and humidity are obtained by an ambient sensor, for example, by a digital temperature and humidity sensor or a combination of discrete temperature and humidity sensors. The ambient sensor periodically collects data at a preset sampling frequency (such as once per minute), or is triggered by the control module for real-time collection. It should be noted that during the operation of the refrigerator, especially in the freezer compartment, the ambient temperature and humidity are key external factors affecting the condensation phenomenon. When the external environment is at a high temperature, such as greater than 30°C, due to the low temperature of the surface of the refrigerator, such as the surface of the freezer compartment, the water vapor in the surrounding air is likely to condense into dew when it comes into contact with the low-temperature surface. However, the higher the ambient humidity, the greater the partial pressure of water vapor in the air, and it is more likely to reach the saturation state when contacting the low-temperature surface, resulting in a significant increase in the amount of condensation. It can be understood that by obtaining the current ambient temperature and humidity, it can be used to determine whether the target part of the refrigerator, such as the freezer door frame, targeted by the anti-condensation tube is in a state prone to condensation, and then adjust the working state of the anti-condensation tube.

[0048] Step S102: Determine the target humidity value according to the ambient temperature;

[0049] It should be noted that the target humidity value is used as a reference value for comparison with the current ambient humidity. That is, when the current ambient humidity is greater than the target humidity value, it indicates that the condensation risk of the condensation-prone part of the current refrigerator is relatively high. When the current ambient humidity is less than or equal to the target humidity value, it indicates that the condensation risk of the condensation-prone part of the current refrigerator is low. It can be understood that the higher the ambient temperature, the easier it is for the refrigerator to condensate, and the corresponding target humidity value should be reduced to avoid the occurrence of condensation in advance. When the ambient temperature is relatively low, the refrigerator is relatively less likely to condensate, and the corresponding target humidity value can be increased to prevent excessive anti-condensation of the refrigerator and waste of energy. There is, for example, a negative correlation between the ambient temperature and the target humidity value.

[0050] Step S103: When the ambient humidity exceeds the target humidity value, control the switch to switch to the first state; when the ambient humidity is less than or equal to the target humidity value, control the switch to switch to the second state.

[0051] When the ambient humidity exceeds the target humidity value, it indicates that the condensation risk of the condensation-prone parts of the current refrigerator is relatively high. Switching the control switch to the first state allows the refrigerant to flow through the anti-condensation tube. When the refrigerant flows through the anti-condensation tube, heat exchange occurs with the target part targeted by the anti-condensation tube to heat the target part, thereby preventing condensation from occurring on the target part. When the ambient humidity is lower than or equal to the target humidity value, it indicates that the condensation risk of the condensation-prone parts of the current refrigerator is low. By switching the control switch to the first state, the refrigerant does not flow through the anti-condensation tube but directly flows to the condenser through the connecting pipe between the compressor and the condenser. In this way, on the one hand, the increased refrigerant flow enhances the heat dissipation effect of the condenser, reduces the condensation temperature, can reduce the work done by the compressor, and achieves the effect of reducing the energy consumption of the refrigeration system; on the other hand, it can reduce the ineffective heat load of the refrigeration system and achieve an energy-saving effect.

[0052] The control method of the refrigerator provided by the embodiment of the present application dynamically adjusts the target humidity value used as a reference value according to the ambient temperature, and determines the condensation risk degree of the target part of the refrigerator targeted by the current anti-condensation tube by comparing the current ambient humidity with the target humidity value. Furthermore, by controlling the working state of the control switch, the anti-condensation tube is only in the working state when the condensation risk is relatively high, achieving the effects of reducing the energy consumption of the refrigerator and saving energy and reducing emissions.

[0053] Regarding how to dynamically adjust the target humidity value according to the ambient temperature, the present application provides an embodiment as follows. In step S102, determining the target humidity value according to the ambient temperature includes:

[0054] Determining the target temperature range from multiple preset temperature ranges based on the ambient temperature;

[0055] Determining the corresponding target humidity value from multiple preset humidity values based on the target temperature range, and multiple preset temperature ranges correspond to multiple preset humidity values one by one.

[0056] Exemplarily, the multiple preset temperature ranges do not overlap with each other. When the ambient temperature falls within one of the multiple preset temperature ranges, the preset temperature range that is fallen into is used as the target temperature range. For example, the multiple preset temperature ranges include a first temperature range (less than 8°C), a second temperature range (8°C - 13°C), a third temperature range (13°C - 19°C), a fourth temperature range (19°C - 35°C), and a fifth temperature range (greater than or equal to 35°C). Correspondingly, the multiple preset humidity values include a first humidity value (75%), a second humidity value (55%), a third humidity value (35%), a fourth humidity value (25%), and a fifth humidity value (15%). Then, when the ambient temperature is 15°C, the determined target temperature range that it falls into is the third temperature range, and the target humidity value is determined to be 35%. Among them, the multiple preset temperature ranges, the multiple preset humidity values, and their corresponding relationships can be pre-stored in the refrigerator, or the refrigerator can obtain them from the outside, such as the system cloud platform, through the communication module.

[0057] In some embodiments, it further includes that when it is detected that the duration for which the ambient temperature is in a high-temperature temperature range, such as the fourth temperature range or the fifth temperature range, exceeds a preset duration, the target humidity value can be adaptively adjusted, such as reduced by 5%; and when it is detected that the duration for which the ambient temperature is in a low-temperature temperature range, such as the first temperature range, exceeds the preset duration, the target humidity value is adaptively adjusted, such as increased by 5%. Among them, the preset duration is determined by the designer according to actual needs and is, for example, 3 hours.

[0058] It should be noted that the division of the preset temperature ranges can be an equally spaced division, or it can be determined by the designer according to the condensation critical conditions of the target part targeted by the anti-condensation pipe and the regional climate data. For example, first, the regional ambient temperature range is determined based on the region where the refrigerator is placed, and then the regional ambient temperature range is divided according to the condensation critical conditions to obtain multiple preset temperature ranges. In addition, the preset humidity value corresponding to each preset temperature range can be determined by the designer through multiple condensation tests with controlled variables. For example, the designer fixes the ambient temperature parameter and controls the change of the ambient humidity parameter multiple times, such as changing it to 15%, 25%, 35%,..., 95% in sequence, to test whether the target part targeted by the anti-condensation pipe condenses each time and make records; after testing the condensation conditions for multiple ambient humidity parameters under each fixed ambient temperature parameter, experimental table data can be obtained, and this experimental table data can be used to determine the preset humidity value corresponding to each preset temperature range. For example, when the ambient temperature parameter is in the second temperature range (8°C - 13°C), it is tested that when the ambient humidity is greater than 55%, condensation occurs on the target part, then the preset humidity value corresponding to the second temperature range is determined to be 55%.

[0059] In a parallel embodiment, in step S102, determining the target humidity value according to the ambient temperature includes:

[0060] Inputting the ambient temperature into a first electrical signal model to obtain the target humidity value, where the first electrical signal model is trained based on at least one set of sample data, and the sample data includes sample ambient temperature and the corresponding sample humidity value.

[0061] Among them, the sample data is obtained by the designer according to the actual test results. The data in the sample data should ensure accuracy, and the amount of data should be sufficient to ensure the calculation accuracy of the processing model. In some embodiments, before training the processing model with the sample data, a series of data processing operations such as preprocessing and unbalanced class processing can also be performed on the original sample data. On the one hand, it can prevent the classification model from not working due to data reasons. On the other hand, it can accelerate the training of the classification model, improve the accuracy of the algorithm, and improve the adaptability of the classification algorithm model to unbalanced data sets.

[0062] In some embodiments, the switching element includes a first valve, and the opening degree of the first valve can adjustably change the refrigerant flow rate in the anti-condensation tube; after controlling the switching element to switch to the first state in the above step S103, it may further include:

[0063] Determining the target opening degree of the first valve according to the ambient humidity and the target humidity value;

[0064] Controlling the first valve to open to the target opening degree.

[0065] It should be noted that the refrigerant flow rate in the anti-condensation tube directly affects the heat exchange efficiency of the anti-condensation tube, and thus affects the heat compensation ability for the anti-condensation part. When the refrigerant flow rate in the anti-condensation tube is too small, the heat compensation for the anti-condensation part is too little, which may lead to a poor anti-condensation effect; when the refrigerant flow rate in the anti-condensation tube is too large, the heat compensation for the anti-condensation part is too much, which will cause waste of energy. When the first valve is opened to the target opening degree, the refrigerant flow rate in the anti-condensation tube can be matched with the actual heat compensation amount required by the anti-condensation part, so as to avoid energy waste while achieving a better anti-condensation effect. For the actual heat compensation amount required by the anti-condensation part, it can be determined according to the relationship between the ambient humidity and the target humidity value.

[0066] It can be understood that when the ambient humidity is greater than the target humidity value, it indicates that the condensation risk of the target part of the refrigerator targeted by the current anti-condensation tube is high. On the other hand, the higher the ambient humidity, the higher the condensation rate of the target part, and the greater the actual heat compensation amount required by the anti-condensation part, that is, the difference between the ambient humidity and the target humidity value is positively correlated with the target opening degree of the first valve. Optionally, determining the target opening degree of the first valve according to the ambient humidity and the target humidity value includes:

[0067] Calculate the first difference between the ambient humidity and the target humidity value;

[0068] Determine the target humidity range from multiple preset humidity ranges based on the first difference;

[0069] Determine the corresponding target opening degree from multiple preset opening degrees based on the target humidity range, where the multiple preset humidity ranges and the multiple preset opening degrees correspond one by one.

[0070] Exemplarily, the multiple preset humidity ranges do not overlap with each other. When the first difference falls within one of the preset humidity ranges among the multiple preset humidity ranges, the preset humidity range into which it falls is used as the target humidity range. For example, the multiple preset humidity ranges include a first humidity range (0 - 10%), a second humidity range (10% - 20%), and a third humidity range (greater than 20%). Correspondingly, the multiple preset opening degrees include a first opening degree (1 / 2), a second opening degree (2 / 3), and a third opening degree (1). Then, when the first difference is 15%, it is determined that the target humidity range into which it falls is the second humidity range, and the target opening degree is determined to be 2 / 3. Among them, the multiple preset humidity ranges, the multiple preset opening degrees, and their corresponding relationships can be pre-stored in the refrigerator, or the refrigerator can obtain them from an external source such as a system cloud platform through a communication module.

[0071] In an alternative embodiment, determining the target opening degree of the first valve according to the ambient humidity and the target humidity value includes:

[0072] Calculate the first difference between the ambient humidity and the target humidity value;

[0073] Input the first difference into a second electrical signal model to obtain the target opening degree, where the second electrical signal model is trained based on at least one set of sample data, and the sample data includes a sample humidity difference and a sample opening degree corresponding to the sample humidity difference.

[0074] Among them, the sample data is obtained by designers based on actual test results.

[0075] The control method of the refrigerator provided by the embodiments of the present application dynamically adjusts the target humidity value used as a reference value according to the ambient temperature, and determines the condensation risk degree of the target part of the refrigerator for which the current dew prevention tube is targeted by comparing the current ambient humidity with the target humidity value. Furthermore, by controlling the working state of the switching element, the dew prevention tube is only in the working state when the condensation risk is relatively high, achieving the effect of reducing the energy consumption of the refrigerator and saving energy and reducing emissions.
