Description

Technical Field

[0001] This application belongs to the field of refrigeration equipment control technology, and more specifically, relates to an air-cooled refrigerator and a control method for an air-cooled refrigerator. Background Technology

[0002] Air-cooled refrigerators are widely used refrigeration and preservation equipment in daily life. Existing air-cooled refrigerators use a control method that takes the temperature of the refrigerator compartment as the main control basis. The compressor and fan motor are controlled to start and stop based on the comparison between the real-time temperature of the refrigerator compartment and the start and stop temperature threshold.

[0003] To regulate the distribution of cooling capacity between the refrigerator and freezer compartments, refrigerators typically have a damper slider structure along the airflow path. To prevent the freezer compartment from becoming cold due to lack of airflow and cooling failure if the damper is completely closed, existing damper sliders are equipped with a minimum non-closable opening. During operation, this minimum opening remains constant, continuously supplying a basic amount of cooling capacity to the freezer compartment.

[0004] When the ambient temperature is low, the external environment itself has sufficient cooling capacity, the heat load of the cold storage room is small, and the cooling capacity is continuously supplied through the minimum opening of the air damper, which causes the temperature of the cold storage room to drop rapidly. This can easily cause the refrigeration system to shut down prematurely and the refrigeration operation time to be short.

[0005] Existing technologies often address these issues by replacing automatic electronically controlled dampers, adding control hardware, or setting forced delayed shutdown. These methods not only increase the overall material cost and control logic complexity but also easily lead to derivative problems such as overcooling of the refrigerator compartment, increased energy consumption, and poor compatibility of the control logic. It is difficult to achieve both effective refrigeration and preservation under different ambient temperatures and meet the required freezer temperature without increasing the cost of hardware modifications to the refrigerator. Summary of the Invention

[0006] The purpose of this application is to provide a frost-free refrigerator and a control method for the frost-free refrigerator, aiming to solve the technical problem in the prior art that it is difficult to balance the refrigeration and preservation effect under different ambient temperatures and the use requirements of meeting the temperature of the freezer compartment without increasing the cost of hardware modification of the refrigerator.

[0007] To achieve the above objectives, according to a first aspect of this application, a frost-free refrigerator is provided, comprising: The cabinet contains a refrigerator compartment, a freezer compartment, and a controller.

The first distance between the fan motor and the first temperature sensing element is greater than the second distance between the fan motor and the second temperature sensing element, so that the temperature drop rate of the freezer compartment is faster than the temperature drop rate of the refrigerator compartment; The controller is connected to the fan motor; the controller is configured to: Obtain the real-time ambient temperature of the environment in which the air-cooled refrigerator is located; If the real-time ambient temperature is within a preset low temperature range, a first adjustment command is output. The preset low temperature range is determined based on a first preset temperature and a second preset temperature, wherein the first preset temperature is less than the second preset temperature. The first adjustment command is used to instruct the fan motor to reduce its operating speed. The refrigeration start-up time of the cold storage compartment is negatively correlated with the operating speed.

[0008] The beneficial effects of the embodiments in this application compared with the prior art are: In this embodiment, no additional detection or control hardware is required for the refrigerator.

The first adjustment command is used to instruct the fan motor to reduce its operating speed. The refrigeration start-up time of the cold storage compartment is negatively correlated with the operating speed.

[0022] First, the application background of the embodiments in this application will be explained so that those skilled in the art can understand it.

[0023] Air-cooled refrigerators are widely used refrigeration and preservation equipment in daily life. They are usually equipped with a refrigerator compartment and a freezer compartment, as well as an evaporator, a fan motor and a controller. The evaporator generates cold air, and the fan motor delivers the cold air to the refrigerator compartment and the freezer compartment respectively, so as to achieve refrigeration and temperature control of different storage compartments.

[0024] Existing air-cooled refrigerators typically have temperature sensing elements installed in the refrigerator compartment and freezer compartment respectively. The industry generally adopts a control method that uses the refrigerator compartment temperature as the main control basis. The compressor and fan motor are controlled to start and stop based on the comparison between the real-time temperature of the refrigerator compartment and the start-stop temperature threshold.

[0025] To regulate the distribution of cooling capacity between the refrigerator and freezer compartments, refrigerators typically have a damper slider structure along the airflow path. To prevent the freezer compartment from becoming cold due to lack of airflow and cooling failure if the damper is completely closed, existing damper sliders are equipped with a minimum non-closable opening. During operation, this minimum opening remains constant, continuously supplying a basic amount of cooling capacity to the freezer compartment.

[0026] When the ambient temperature is low, the external environment itself has sufficient cooling capacity, the heat load of the cold storage room is small, and the cooling capacity is continuously supplied through the minimum opening of the air damper, which causes the temperature of the cold storage room to drop rapidly. It is very easy to quickly reach the preset shutdown temperature threshold, causing the refrigeration system to shut down prematurely and the refrigeration operation time to be short.

[0027] The freezer compartment is set to a low storage temperature and has a high cooling requirement. A short refrigeration cycle cannot meet the cooling needs of the freezer compartment, which can easily lead to the actual temperature of the freezer compartment being too high and failing to meet the prescribed storage temperature standard, thus affecting the preservation and storage effect of frozen food.

[0028] Existing technologies often address these issues by replacing automatic electronically controlled dampers, adding control hardware, or setting forced delay shutdowns. These methods not only increase the overall material cost and control logic complexity but also easily lead to derivative problems such as overcooling of the refrigeration compartment, increased energy consumption, and poor compatibility of the control logic. It is difficult to achieve both refrigeration and preservation effects under different ambient temperatures and meet the temperature requirements of the freezer compartment without altering the existing hardware structure or adding new electronic control components.

[0029] This application provides an example of an embodiment of a frost-free refrigerator. Figure 1 The diagram shown is a schematic structural diagram of a frost-free refrigerator provided in this application. It is provided as an example and not as a limitation. Please refer to it. Figure 1 As shown, the air-cooled refrigerator includes: The cabinet 100 contains a refrigerator compartment 101, a freezer compartment 102, and a controller (such as a control chip, which may be located inside the cabinet or at the rear corresponding to the front of the door, not shown in the figure). The freezer compartment 102 contains an evaporator (which may be located inside the cabinet or at the rear corresponding to the front of the door, not shown in the figure) and a fan motor 103 corresponding to the evaporator.

[0030] An evaporator is used to generate the cooling capacity required for refrigeration operation.

[0031] The fan motor 103 is used to drive the cold energy generated by the evaporator to be delivered to the cold storage compartment and the freezer compartment.

[0032] The refrigerator compartment 101 is equipped with a first temperature sensing element 101a for collecting the real-time temperature of the refrigerator compartment 101, and the freezer compartment 102 is equipped with a second temperature sensing element 102a for collecting the real-time temperature of the freezer compartment 102.

[0033] The first distance between the fan motor 103 and the first temperature sensing element 101a is greater than the second distance between the fan motor 103 and the second temperature sensing element 102a, so that the temperature drop rate of the freezer compartment 102 is faster than the temperature drop rate of the refrigerator compartment 101.

[0034] The controller is connected to the fan motor (internal electrical connection); the controller is configured as follows: Obtain the real-time ambient temperature of the environment where the air-cooled refrigerator is located.

[0035] If the real-time ambient temperature is within the preset low temperature range, the first adjustment command will be output.

[0036] The preset low temperature range is determined based on the first preset temperature and the second preset temperature. The first preset temperature is lower than the second preset temperature. The first adjustment command is used to instruct the fan motor to reduce its operating speed. The refrigeration start-up time of the cold storage compartment is negatively correlated with the operating speed.

[0037] In some embodiments, the air-cooled refrigerator (hereinafter referred to as the refrigerator) of this embodiment includes a cabinet, inside which are arranged a refrigerator compartment, a freezer compartment, and a controller. An evaporator and a fan motor are correspondingly arranged inside the freezer compartment. The evaporator, as a refrigeration heat exchange component, is used to generate the cooling capacity required for the refrigerator's operation through refrigeration cycle heat exchange. The fan motor is correspondingly arranged with the evaporator to drive the stable delivery of the cooling capacity generated by the evaporator to the refrigerator compartment and the freezer compartment, meeting the daily cooling and air supply needs of the two storage compartments in the air-cooled refrigerator.

[0038] In some embodiments, a first temperature sensing element is installed inside the refrigerator compartment to collect the actual temperature of the refrigerator compartment in real time; a second temperature sensing element is installed inside the freezer compartment to collect the actual temperature of the freezer compartment in real time, providing a basic temperature basis for judging the operating conditions and logic control of the air-cooled refrigerator.

[0039] In some embodiments, it is still as follows Figure 1 As shown, the fan motor 103 is arranged with a fixed spacing from the first temperature sensing element 101a and the second temperature sensing element 102a. The first arrangement distance H1 between the fan motor 103 and the first temperature sensing element 101a is greater than the second arrangement distance H2 between the fan motor 103 and the second temperature sensing element 102a (i.e., H1 > H2).

[0040] It should be understood that, under the same conditions of air supply area and cold energy distribution ratio, the closer the air supply distance, the smaller the cold energy transmission loss, and the more advantageous the air supply speed and air volume, the faster the temperature of the corresponding compartment drops, thus enabling the freezer compartment to have a faster temperature drop rate than the refrigerator compartment.

[0041] In some embodiments, an electrical connection is established between the controller and the fan motor. The controller is configured to continuously acquire the real-time ambient temperature of the external environment where the refrigerator is located during normal operation. The preset low-temperature range is defined by a first preset temperature and a second preset temperature, where the value of the first preset temperature is less than the value of the second preset temperature. This is used to define the applicable range of low-temperature operating conditions for adaptive speed adjustment. The first and second preset temperatures can also be adaptively calibrated according to the refrigerator's climate rating and overall structural parameters.

[0042] In some embodiments, when the controller detects that the real-time ambient temperature is within a preset low-temperature range, the controller outputs a first adjustment command to the fan motor, which instructs the fan motor to reduce its operating speed. In this embodiment, the refrigeration start-up time of the cold storage compartment is negatively correlated with the fan motor's operating speed; that is, the lower the fan motor's operating speed, the smoother the cold energy is delivered to the distant cold storage compartment, the slower the cooling speed of the cold storage compartment, and the longer the refrigeration system remains operational.

[0043] It should be understood that the structural layout and control logic of this air-cooled refrigerator can be achieved using the existing hardware configuration without altering the original damper structure or minimum opening size, nor requiring additional electronic control components or heating auxiliary structures. In low-temperature environments, by reducing the fan motor speed, the cooling operation time of the refrigerator compartment is extended, increasing the overall cooling operation rate of the refrigerator. Utilizing the inherent characteristics of the closer proximity and faster cooling rate of the freezer compartment, the freezer compartment temperature is ensured to meet standard storage requirements without altering the refrigerator's original control logic in high-temperature environments, thus balancing the needs of both refrigeration and freezing under all environmental conditions.

[0044] In this embodiment, no additional detection or control hardware is required for the refrigerator. The control logic can be implemented solely based on the refrigerator's built-in temperature sensing element, evaporator, fan motor, and controller. It is compatible with existing conventional air-cooled refrigerators, offering strong versatility and practicality. This control logic effectively addresses the technical issues of premature shutdown in low-temperature environments and insufficient cooling in the freezer, thereby improving the overall operational stability of the refrigerator and the user experience.

[0045] In some embodiments, the controller is connected to the first temperature sensing element, such as Figure 2 As shown, the controller is also configured to perform the following method steps: S201, acquire the real-time temperature of the cold storage compartment collected by the first temperature sensing element.

[0046] S202, based on the comparison results of the real-time temperature of the cold storage compartment with the preset start-up temperature and preset stop temperature, obtains the refrigeration start-up time and refrigeration stop time of the cold storage compartment.

[0047] S203, the total duration is calculated based on the cooling start-up time and cooling shutdown time.

[0048] S204 defines the ratio of cooling start-up time to total start-up time as the cooling start-up coefficient.

[0049] The refrigeration start-up coefficient is used to characterize the proportion of refrigeration start-up time in the total time. This allows the refrigeration start-up coefficient to be changed and the refrigeration start-up time to be extended by adjusting the operating speed of the fan motor within the preset low temperature range, so that the real-time temperature of the freezer compartment does not exceed the target freezing temperature.

[0050] In some embodiments, the controller establishes an electrical connection with a first temperature sensing element, which is arranged inside the refrigerator compartment and can continuously sense and output real-time temperature data of the refrigerator compartment. The controller can obtain the real-time temperature of the refrigerator compartment collected by the first temperature sensing element in real time, providing a temperature input basis for determining the refrigeration status of the refrigerator compartment.

[0051] In some embodiments, while continuously receiving the real-time temperature of the cold storage compartment, the controller compares the real-time temperature with the preset start-up temperature and preset stop temperature in real time. Based on the temperature comparison results, it identifies the refrigeration start-up state and the refrigeration stop-up state of the cold storage compartment, and then calculates the refrigeration start-up time and the refrigeration stop-up time in a single working cycle of the cold storage compartment.

[0052] Among them, the preset start-up temperature and preset stop-up temperature are fixed threshold parameters calibrated for the entire refrigerator. They can be adapted and set according to the product's climate type and storage preservation needs, serving as the benchmark conditions for determining the start-up and stop-up switching of the refrigeration system.

[0053] In some embodiments, the controller performs calculations based on the statistically obtained refrigeration start-up time and refrigeration stop time to obtain the total duration corresponding to a single complete working cycle. This total duration is jointly defined by the refrigeration start-up time and refrigeration stop time and is used to objectively reflect the working cycle duration of a complete start-up and stop cycle of the cold storage room.

[0054] In some embodiments, the controller calculates the ratio of the refrigeration start-up time to the total duration and defines this ratio as the refrigeration start-up coefficient. In this embodiment, the refrigeration start-up coefficient is used to characterize the proportion of refrigeration start-up time in the total duration of the complete working cycle. It can intuitively reflect the duty cycle level of the refrigeration operation time of the cold storage compartment and serve as an important parameter for quantitatively evaluating the overall refrigeration workload.

[0055] In some embodiments, within a preset low-temperature range, the cooling rate of the cold storage compartment can be indirectly changed by adjusting the operating speed of the fan motor, thereby adjusting the value of the refrigeration start-up coefficient and achieving active control over the extension of the refrigeration start-up time. By extending the refrigeration start-up time, sufficient cooling time can be reserved for the freezer compartment, thus ensuring that the real-time temperature of the freezer compartment is stably controlled within a range not exceeding the target freezing temperature, meeting the standard storage temperature requirements of the freezer compartment under low-temperature conditions.

[0056] This embodiment relies solely on the refrigerator's existing first temperature sensing element and controller to complete temperature acquisition, status determination, duration statistics, and coefficient calculation. No additional detection devices or hardware structures are required, resulting in a compact logic nesting and easy program implementation. The quantitative definition of the cooling start-up coefficient provides a quantifiable basis for cooling control under low-temperature conditions, facilitating coordination with strategies such as ambient temperature range determination and graded adjustment of fan motor operating speed. This further enhances the accuracy and operational stability of the refrigerator's cooling control under different environmental conditions.

[0057] In some embodiments, the controller is also configured to: If the real-time ambient temperature is within the preset high temperature range, a second adjustment command is output. The second adjustment command is used to indicate that the rated operating speed of the fan motor should be maintained. The preset high temperature range is determined based on a second preset temperature and a third preset temperature, where the second preset temperature is lower than the third preset temperature.

[0058] In some embodiments, the preset high temperature range is defined by a second preset temperature and a third preset temperature, wherein the value of the second preset temperature is less than the value of the third preset temperature. This preset high temperature range is connected to the aforementioned preset low temperature range and can be calibrated according to parameters such as the refrigerator's climate suitability level and the overall refrigeration power, in order to accurately classify the high temperature applicable operating conditions that require maintaining the rated speed of the fan.

[0059] In some embodiments, the controller compares the real-time ambient temperature with the second preset temperature and the third preset temperature in real time. When it is determined that the real-time ambient temperature is within the preset high temperature range, the controller outputs a second adjustment command to the fan motor. The second adjustment command is used to instruct the fan motor to maintain its rated operating speed.

[0060] In this embodiment, the rated operating speed of the fan motor is a pre-calibrated standard operating speed, which maximizes the efficiency of cold air delivery and adapts to the refrigeration needs under high-temperature conditions. Within the preset high-temperature range, the ambient temperature is high, and the heat load of both the refrigeration and freezing compartments is at a high level. Maintaining the rated speed of the fan motor ensures that the cold air generated by the evaporator can be quickly and sufficiently delivered to the two storage compartments, accelerating the cooling rate of the compartments and preventing the compartment temperature from exceeding the standard due to insufficient cold air delivery, thus ensuring the effectiveness of refrigeration preservation and freezing temperature control under high-temperature conditions.

[0061] It should be noted that the control logic for this high-temperature operating condition works in conjunction with the aforementioned speed reduction logic for the low-temperature operating condition, clearly defining the fan control strategy for different ambient temperature ranges. This allows the controller to automatically switch control modes based on changes in ambient temperature without manual intervention. Furthermore, this logic relies solely on the existing ambient temperature sensor and fan control components, requiring no additional hardware. This ensures both cooling efficiency under high-temperature conditions and meets freezing requirements under low-temperature conditions, further enhancing the refrigerator's overall reliability and adaptability to various climatic conditions.

[0062] In some embodiments, a damper slider is also provided on the cold air supply path inside the cabinet. The damper slider includes a manual damper slider or an automatic damper slider. The damper slider is used to adjust the cold air distribution ratio to the refrigerator compartment and the freezer compartment, and to keep the minimum passage opening constant. A controller is connected to the damper slider and executes the output of a first adjustment command. The controller is configured to output the first adjustment command without changing the damper slider's position and opening state.

[0063] In some embodiments, a damper slider (manual or automatic) is also provided on the cold air supply path inside the cabinet. The damper slider includes manual and automatic damper sliders, and its function is to adjust the cold air distribution ratio to adapt to the cold air demand under different operating conditions. The damper slider is provided with a fixed minimum passage opening, so that even at the minimum setting, the basic cold air supply to the freezer compartment can be guaranteed, avoiding the problem of no cold air on the freezer side due to the damper being closed.

[0064] Furthermore, in this embodiment, the damper sliders are all equipped with a fixed minimum opening size, which is a preset fixed value and does not change with operating conditions. The purpose is to ensure that the freezer compartment can receive a basic cooling capacity regardless of the ambient temperature. Moreover, the minimum opening design of the damper sliders, in conjunction with the fan motor's operating speed adjustment logic described above, allows for dynamic adaptation of cooling capacity distribution under low-temperature conditions without changing the damper setting or adjusting the opening size; simply by controlling the fan motor's operating speed.

[0065] In some embodiments, when the controller detects that the ambient temperature is in the low-temperature range, it outputs an adjustment command. Without changing the position of the damper slider or adjusting the minimum opening of the damper slider, it only reduces the speed of the fan motor to slow down the cooling rate of the refrigerator compartment, thereby extending the refrigeration start-up time and ensuring that the freezer compartment receives sufficient cooling time, ultimately achieving the target temperature for the freezer compartment.

[0066] In addition, in this embodiment, the controller and the damper slider (manual or automatic) are linked. No additional hardware is required. Only through software logic adjustment, the minimum opening of the damper can be continuously output cold air. At the same time, with the increase of the refrigeration start-up coefficient, the cold air supply to the freezer compartment is ensured to be stable, avoiding shutdowns caused by the refrigerator side reaching the standard quickly. This ensures that the temperature of the freezer compartment remains stable within the preset standard.

[0067] Furthermore, in this embodiment, the controller, the damper slider (manual or automatic), and the fan motor form a control closed loop: the controller collects ambient temperature and temperature sensing data, determines whether the fan motor's operating speed needs to be adjusted, and then adjusts the refrigeration start-up time. Through the optimization of cold energy distribution, the freezer compartment temperature reaches the standard, which can avoid the hardware cost of modifying the damper and ensure the basic cold energy supply of the minimum opening of the damper, thereby improving the overall operational stability and adaptability of the refrigerator.

[0068] In some embodiments, the housing also includes a compressor and a potentiometer; A compressor is used to drive the refrigerant to circulate in the refrigeration circuit to achieve refrigeration operation; The potentiometer has multiple adjustment levels for setting the target temperature range of the refrigerator compartment. The adjustment level value is negatively correlated with the target temperature of the refrigerator compartment. The controller is electrically connected to the compressor and the potentiometer respectively; the controller is also configured to match the adjustment range of the potentiometer with the travel range of the damper slider, so as to help ensure that the real-time temperature of the freezer compartment does not exceed the target freezing temperature within the preset low temperature range, and to reserve a temperature margin.

[0069] In some embodiments, the compressor, as the power component of the refrigeration system, mainly drives the refrigerant to circulate in the refrigeration circuit. It achieves the refrigeration effect by absorbing heat through the phase change of the refrigerant, providing a continuous basis for the refrigeration system to output cold energy. It is the power source for cooling the freezer and refrigerator compartments. It works in conjunction with the fan air supply and temperature control logic mentioned above to ensure the normal operation of the refrigeration cycle.

[0070] In some embodiments, the potentiometer serves as a temperature control component and has multiple adjustable levels. Different levels correspond to different target temperature ranges for the refrigerator compartment, and the value of the adjustable level is negatively correlated with the target temperature of the refrigerator compartment. That is, the higher the level value, the lower the target temperature of the refrigerator compartment; the lower the level value, the higher the target temperature of the refrigerator compartment. It can be flexibly adjusted according to user needs to adapt to different preservation requirements.

[0071] In some embodiments, the controller is electrically connected to both the compressor and the potentiometer, enabling it to acquire the potentiometer's adjustment level signal in real time and receive the target temperature parameter set by the potentiometer, thereby matching the corresponding control logic. In actual operation, the controller can also synchronously match the cooling capacity distribution ratio of the damper slider according to the potentiometer's adjustment level, ensuring that the cooling capacity supply is adapted to the target temperature and avoiding problems such as overcooling in refrigeration or under-freezing due to improper adjustment.

[0072] Crucially, the controller can also match the potentiometer's adjustment range with the damper slider's travel range. By precisely coordinating the two, it can assist in extending the cooling start-up time within the preset low temperature range, ensuring that the freezer compartment receives sufficient cooling time. This allows the freezer compartment temperature to stabilize within the preset standard and reserves enough temperature margin to avoid technical problems such as temperature non-compliance caused by operating condition fluctuations.

[0073] It should be noted that this setup requires no new hardware. It achieves coordinated control of existing components through the controller, enabling the potentiometer settings, damper opening, and fan motor speed to be synchronized. This ensures both the temperature accuracy of the refrigerator compartment and the temperature of the freezer compartment, balancing refrigeration efficiency and ease of use. It avoids the increased costs associated with additional hardware investment, adapts to the low ambient temperature adaptation requirements mentioned earlier, and further improves the integrity and reliability of the control system.

[0074] In some embodiments, the controller is also configured to: If the real-time temperature of the refrigerator compartment reaches the preset shutdown temperature, and the real-time temperature of the freezer compartment is not higher than the target freezing temperature, then the compressor and fan motor will be controlled to stop refrigeration operation. If the real-time temperature of the refrigerator compartment reaches the preset shutdown temperature, but the real-time temperature of the freezer compartment is higher than the target freezing temperature, the compressor and fan motor will continue to operate in a cooling mode until the real-time temperature of the freezer compartment is no higher than the target freezing temperature.

[0075] In some embodiments, the controller continuously collects the real-time temperatures of the refrigerator compartment and the freezer compartment, and presets a shutdown temperature (i.e., a preset shutdown temperature) for the refrigerator compartment and a preset temperature (i.e., a target freezing temperature) for the freezer compartment. When the controller detects that the real-time temperature of the refrigerator compartment has reached the preset shutdown temperature, it first determines whether the real-time temperature of the freezer compartment has reached the preset temperature requirement. If the real-time temperature of the refrigerator compartment reaches the preset shutdown temperature, and the real-time temperature of the freezer compartment is no higher than the target freezing temperature, it means that both have reached the temperature standard. At this time, the controller can control the compressor and fan motor to stop running, complete one refrigeration cycle, and avoid energy waste and food damage caused by over-cooling.

[0076] If the real-time temperature of the refrigerator compartment has reached the preset shutdown temperature, but the real-time temperature of the freezer compartment is still higher than the target freezing temperature, it means that the freezer compartment has not received enough cooling time. In this case, the controller can maintain the operation of the compressor and fan motor and not stop the cooling work until the real-time temperature of the freezer compartment drops below the preset temperature, and then stop the cooling operation.

[0077] Therefore, this embodiment effectively avoids the problem of insufficient cooling in the freezer compartment due to the refrigerator compartment reaching its shutdown temperature prematurely. It ensures both precise temperature control in the refrigerator compartment and the freezer compartment reaches the specified temperature standard, thus accommodating the usage needs of both compartments. Furthermore, this control logic requires no additional hardware; precise temperature control of both compartments can be achieved solely through software optimization, further improving the overall reliability of the refrigerator, ensuring stable operation of the refrigeration system, and adapting to usage needs in different environments.

[0078] In some embodiments, the controller is also configured to: After the compressor and fan motor stop refrigeration operation, the real-time temperature of the cold storage compartment is continuously monitored; If the real-time temperature of the refrigerator compartment rises back to the preset start-up temperature, then return to the step of obtaining the real-time ambient temperature of the environment where the frost-free refrigerator is located.

[0079] In some embodiments, after the controller completes the shutdown control of the compressor and fan motor, it does not terminate the operating condition monitoring logic. Instead, it continues to monitor the temperature change status of the refrigerator compartment in real time based on the first temperature sensing element, and monitors the temperature rise trend of the refrigerator compartment at any time, so as to provide a basis for determining the start of the next refrigeration cycle.

[0080] It should be understood that when the refrigerator compartment is in a static, off-state phase, its real-time temperature will gradually and slowly rise due to factors such as heat exchange within the refrigerator body, heat infiltration from the external environment, and heat release from the food inside. The controller compares the real-time temperature of the refrigerator compartment with the preset start-up temperature in real time. Once it detects that the real-time temperature of the refrigerator compartment has risen back to the preset start-up temperature, it determines that the refrigerator as a whole is ready to re-enter the cooling control process.

[0081] In this situation, the controller re-executes the step of obtaining the real-time ambient temperature of the environment where the air-cooled refrigerator is located, and then matches the corresponding fan motor speed control strategy according to the current ambient temperature range, and sequentially completes the control logic such as cooling duration statistics, cooling start-up coefficient calculation and compartment coordinated start-up and shutdown determination.

[0082] This cyclical operation mode allows the refrigerator to adaptively match the control mode with the actual environmental conditions each time it starts and stops cooling, forming a continuous closed-loop control process. It requires no manual intervention and can adapt the control parameters in real time according to the fluctuation of ambient temperature and changes in the heat load inside the refrigerator. It is connected with the aforementioned dual-compartment joint shutdown judgment and high and low temperature range speed adjustment logic to ensure that the refrigerator maintains a reasonable cooling rhythm during long-term operation, taking into account the usage requirements of refrigeration preservation accuracy and stable freezing temperature.

[0083] This application provides an example of a control method for an air-cooled refrigerator. Please refer to [link / reference]. Figure 3 As shown, Figure 3 A schematic flowchart of a control method for an air-cooled refrigerator provided in this application is shown. This is an example and not a limitation; the method can be applied to or operated in an air-cooled refrigerator. The method includes: S301, obtain the real-time ambient temperature of the environment where the air-cooled refrigerator is located.

[0084] S302, if the real-time ambient temperature is within the preset low temperature range, output the first adjustment command.

[0085] The preset low temperature range is determined based on the first preset temperature and the second preset temperature. The first preset temperature is lower than the second preset temperature. The first adjustment command is used to instruct the fan motor to reduce its operating speed. The refrigeration start-up time of the cold storage compartment is negatively correlated with the operating speed.

[0086] In some embodiments, the control method for the air-cooled refrigerator disclosed in this embodiment can be adapted to the air-cooled refrigerator in any of the aforementioned structural embodiments, and the control process is realized by relying on the refrigerator's own controller, temperature sensing element, fan motor and original refrigeration hardware.

[0087] In some embodiments, during the operation of the control method, the real-time ambient temperature of the external environment where the air-cooled refrigerator is located is first collected, which serves as the basis for subsequent operating condition zoning and strategy adjustment. The preset low temperature range is defined by a first preset temperature and a second preset temperature. The first preset temperature value is lower than the second preset temperature value. It can be pre-calibrated according to the applicable climate type and overall operating parameters of the refrigerator, and is used to define the low temperature operating condition range in which the operating speed of the fan motor needs to be intervened.

[0088] In some embodiments, the collected real-time ambient temperature is compared with a preset low-temperature range. When the real-time ambient temperature falls within the preset low-temperature range, a first adjustment command is generated and output. The function of this first adjustment command is to instruct a reduction in the current operating speed of the fan motor, thereby changing the cooling capacity delivery rate by utilizing the inherent difference in the spacing between the fan motor and the temperature sensing elements in the refrigeration and freezing compartments.

[0089] In some embodiments, a stable negative correlation is maintained between the refrigeration start-up time of the refrigerator compartment and the operating speed of the fan motor. Reducing the fan motor speed slows down the rate of cold air delivery from the distant refrigerator compartment, lengthening the temperature drop process and naturally extending the refrigeration start-up time. Leveraging the structural characteristics of the freezer compartment, which is closer to the fan motor and has a faster cooling rate, the refrigeration operation time is extended by lowering the fan speed without altering the damper settings or opening status, or incurring additional hardware costs. This provides sufficient refrigeration time for the freezer compartment, ensuring that the real-time temperature of the freezer compartment remains stable and meets standards under low-temperature conditions.

[0090] This control method is implemented entirely based on the existing hardware architecture of the refrigerator, requiring no additional detection devices or actuators. Ambient temperature identification, temperature range determination, and fan motor speed adjustment are all achieved through the controller's built-in logic. The method features a simple, closed-loop logic that is easy to implement and seamlessly integrates with subsequent processes such as cooling duration statistics, start-up coefficient calculation, and dual-compartment coordinated start-stop control. While maintaining compatibility with the original overall control logic, it effectively addresses the issues of premature shutdown in low-temperature refrigeration conditions and insufficient cooling in freezing conditions, enhancing the operational stability and cooling matching capability of the frost-free refrigerator under all environmental conditions.

[0091] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution.
