Description

Technical Field

[0001] The present application relates to the technical field of refrigerators, and for example, to a control method and device for a single-system refrigerator, and a single-system refrigerator and medium. Background Art

[0002] At present, with the improvement of people's living standards, the popularity of refrigerators is also increasing. Through the operation of its own refrigeration process, the refrigerator can refrigerate or freeze the food stored inside it. Among them, the refrigerator compartment and the freezer compartment of the single-system refrigerator share an evaporator, and the cold is transferred from the freezer compartment to the refrigerator compartment. However, there is usually a big difference in the requirements for the inner tank temperature between the refrigerator compartment and the freezer compartment. The inner tank temperature of the refrigerator compartment is generally maintained at 4℃~5℃ to meet the refrigeration requirements of the food stored inside, while the inner tank temperature of the freezer compartment usually needs to reach -18℃ to ensure the freezing effect of the food stored inside. In order to avoid excessive cold entering the inner tank of the refrigerator compartment and causing the internal stored food to be frozen, a refrigeration damper is provided between the refrigerator compartment and the freezer compartment. By controlling the switch of the refrigeration damper, the cold amount flowing from the freezer compartment to the refrigerator compartment can be adjusted to achieve reasonable control of the inner tank temperature of the refrigerator compartment. Among them, the relevant technology collects the real-time temperature of the cold storage room in real time; when the real-time temperature of the cold storage room is ≤ the set temperature of the cold storage room, the cold storage damper is closed and the airflow driving structure is in a closed state.

[0003] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0004] A foam layer is usually used to seal the interior of the cold storage room and the cold air inlet duct. However, due to factors such as assembly and shrinkage, flash gaps and air leaks are prone to occur at the assembly point. The cold air in the freezer room may penetrate into the interior of the cold storage room, causing the temperature of some areas of the interior of the cold storage room to be too low. Therefore, the relevant technology still has the risk of local food frost.

[0034] At present, with the improvement of people's living standards, the popularity of refrigerators is also increasing. Through the operation of its own refrigeration process, the refrigerator can refrigerate or freeze the food stored inside it. Among them, the refrigerator compartment and the freezer compartment of the single-system refrigerator share an evaporator, and the cold is transferred from the freezer compartment to the refrigerator compartment. However, there is usually a big difference in the requirements for the inner tank temperature between the refrigerator compartment and the freezer compartment. The inner tank temperature of the refrigerator compartment is generally maintained at 4℃~5℃ to meet the refrigeration requirements of the food stored inside, while the inner tank temperature of the freezer compartment usually needs to reach -18℃ to ensure the freezing effect of the food stored inside. In order to avoid excessive cold entering the inner tank of the refrigerator compartment and causing the internal stored food to be frozen, a refrigeration damper is provided between the refrigerator compartment and the freezer compartment. By controlling the switch of the refrigeration damper, the cold amount flowing from the freezer compartment to the refrigerator compartment can be adjusted to achieve reasonable control of the inner tank temperature of the refrigerator compartment. Among them, the relevant technology collects the real-time temperature of the cold storage room in real time; when the real-time temperature of the cold storage room is ≤ the set temperature of the cold storage room, the cold storage damper is closed and the airflow driving structure is in a closed state.

[0035] A foam layer is usually used to seal the interior of the cold storage room and the cold air inlet duct. However, due to factors such as assembly and shrinkage, flash gaps and air leaks are prone to occur at the assembly point. The cold air in the freezer room may penetrate into the interior of the cold storage room, causing the temperature of some areas of the interior of the cold storage room to be too low. Therefore, the relevant technology still has the risk of local food frost.

[0036] Combination Figure 1-2 As shown, the embodiment of the present disclosure provides a single-system refrigerator, including: a box body 10, an evaporator 21, a refrigerated inner tank 31, a refrigerated air duct (not shown in the figure), an environmental sensor 50 and an antifreeze fan 60. The box body 10 is internally configured with a refrigerated compartment 11 and a freezer compartment 12. The evaporator 21 is arranged in the freezer compartment 12 and is used to produce cold air. The refrigerated inner tank 31 is arranged in the refrigerated compartment 11 and is used to store food. The refrigerated air duct includes a refrigerated air inlet duct 41 and a refrigerated air return duct 42, which are used to connect the refrigerated inner tank 31 and the evaporator 21. The environmental sensor 50 is arranged at the connection between the refrigerated inner tank 31 and the refrigerated air inlet duct 41, and is used to detect the leakage of cold air in the refrigerated inner tank 31. The antifreeze fan 60 is arranged in the refrigerated inner tank 31, and is used to discharge the cold air in the refrigerated inner tank 31 through the refrigerated air return duct 42.

[0037] The single-system refrigerator provided by the embodiment of the present disclosure collects environmental parameters of the assembly area through the environmental sensor 50 provided at the connection between the refrigerated inner tank 31 and the refrigerated air inlet duct 41, so that the cold air leakage in the refrigerated inner tank 31 can be detected in real time. When flashing, air leakage and other phenomena occur at the assembly point of the refrigerated inner tank 31 and the refrigerated air inlet duct 41, the embodiment of the present disclosure can identify the cold air leakage phenomenon that is occurring through abnormal environmental parameters, and discharge the leaked cold air through the refrigerated return air duct 42 by running the antifreeze fan 60, so as to avoid the cold energy from accumulating at the cold air leakage point, and solve the problem of local frost of food in the refrigerated inner tank 31.

[0038] Optionally, a refrigeration damper 43 is provided in the refrigeration air inlet duct 41 for adjusting the amount of cold that flows from the evaporator 21 to the refrigeration inner container 31. Preferably, the refrigeration damper 43 is provided relative to the bottom wall of the refrigeration inner container 31. Thus, when the temperature in the refrigeration inner container 31 is low, in order to prevent the cold from overflowing and causing the food stored therein to be frozen, the refrigeration damper 43 can be closed to stop the freezing chamber 12 from transferring cold to the refrigeration chamber 11. Thus, the temperature of the refrigeration inner container 31 can always be within a reasonable range, which is conducive to ensuring the preservation effect of the food in the refrigeration chamber 11.

[0039] Optionally, a sealing layer 33 is provided between the refrigerated inner container 31 and the refrigerated air inlet duct 41. The sealing layer 33 is filled with foam materials such as foam and foam. The sealing layer 33 can prevent the cold in the freezing compartment 12 from entering the refrigerated inner container 31 in a large area and causing the internal food to frost.

[0040] Optionally, a refrigeration fan 22 and a compressor 23 are provided in the freezing chamber 12. The evaporator 21, the refrigeration fan 22, the compressor 23 and the condenser (not shown in the figure) together constitute a refrigeration system. The refrigeration fan 22 is used to transport the cold air produced by the evaporator 21 to the refrigeration liner 31 through the refrigeration air inlet duct 41. The compressor 23 is used to transport and compress the refrigerant so that the refrigerant circulates in the refrigeration system.

[0041] Optionally, a freezing liner 32 is provided in the freezing compartment 12 for storing food materials to meet the freezing requirements of the food materials stored inside.

[0042] Optionally, the single-system refrigerator further includes a freezing air duct, which includes a freezing air inlet duct 81 and a freezing air return duct 82, and is used to connect the freezing liner 32 and the evaporator 21. In this way, by circulating the cold air through the freezing air inlet duct 81 and the freezing air return duct 82, the temperature of the freezing liner 32 can always be within a reasonable range, which is conducive to ensuring the freezing effect of the food in the freezing compartment 12.

[0043] Optionally, the refrigeration air inlet duct 41 is connected to the freezing air inlet duct 81. In this way, the air duct structure inside the single-system refrigerator can be simplified, which is conducive to improving the utilization rate of the internal space.

[0044] Optionally, a refrigerated drawer 70 is provided in the refrigerated inner tank 31, and the refrigerated drawer 70 can be moved in a controlled manner. There can be multiple refrigerated drawers 70, and the specific number is not limited here. In this way, the refrigerated drawer 70 can be used to assist in food storage. On the one hand, the user can manually pull out or push in the refrigerated drawer 70 to store or take food into the refrigerated drawer 70. On the other hand, the refrigerated drawer 70 can be controlled to move in combination with the cold air leakage working condition to avoid the cold air accumulation near the refrigerated drawer 70 causing local frost on the food.

[0045] Optionally, a moving device 71 is provided on the back side of the refrigerated drawer 70 for driving the refrigerated drawer 70 to move. In this way, the refrigerated drawer 70 can be controlled to move autonomously in combination with the cold air leakage working condition to avoid the cold energy gathering near the refrigerated drawer 70 and causing local frost on the food.

[0046] Optionally, the moving device 71 includes a driving component and a transmission component, and the transmission component is connected to the refrigerated drawer 70. Exemplarily, in some embodiments, the driving component is a gear shaft and the transmission component is a rack. In this way, the driving component can drive the transmission component to move horizontally, thereby driving the refrigerated drawer 70 to move autonomously, so as to avoid the cold energy accumulating near the refrigerated drawer 70 and causing local frost on the food.

[0047] Optionally, movable slide rails are provided on both sides of the refrigerated drawer 70 to assist the movement of the refrigerated drawer 70. In this way, the movable slide rails can make the movement of the refrigerated drawer 70 smoother, which is conducive to avoiding local food frost caused by poor movement.

[0048] Optionally, the single-system refrigerator further includes a door body 90, which is disposed on the cabinet 10 and can be controlled to be opened or closed to expose or close the refrigerating compartment 11 or the freezing compartment 12. In this way, the user can open or close the door body 90 to store or take food into or out of the refrigerating compartment 11 or the freezing compartment 12.

[0049] Optionally, the door body 90 is provided with a bottle holder 91. In this way, the storage of food such as beverages can be assisted, which is conducive to improving the user experience.

[0050] Optionally, the environmental sensor 50 is provided at the connection between the refrigerated air inlet duct 41 and the bottom wall of the refrigerated liner 31, and is used to detect the cold air leakage at the bottom of the refrigerated liner 31. At the connection between the refrigerated air inlet duct 41 and the bottom wall of the refrigerated liner 31, below it is the refrigeration area of ​​the freezer compartment 12, and the temperature therein is close to the low temperature of the freezer compartment 12. In a low temperature environment, the foaming material in the sealing layer 33 and the plastic parts such as the refrigerated liner 31 will shrink to a certain extent, and the shrinkage may cause air leakage in the sealing layer 33 area. The coldness in the freezer compartment 12 may penetrate into the refrigerated liner 31, causing the temperature of a local area in the refrigerated liner 31 to be too low, causing local frost on the food, which is not conducive to the user's refrigerator experience. In this way, by setting an environmental sensor 50 at the connection between the refrigerated air inlet duct 41 and the bottom wall of the refrigerated liner 31, the embodiment of the present disclosure can preferentially detect the environmental parameters at the bottom of the refrigerated liner 31 where the probability of cold air leakage is higher, thereby facilitating more accurate identification of cold air leakage and timely resolution.

[0051] Optionally, the environmental sensor 50 is provided at the connection between the section where the refrigeration damper 43 is located in the refrigeration air inlet duct 41 and the refrigeration liner 31, and is used to detect the leakage of cold air in the refrigeration liner 31 near the refrigeration damper 43. When the refrigeration damper 43 is closed, the cold in the freezer compartment 12 cannot be transferred to the refrigeration liner 31 through the refrigeration air inlet duct 41, but the cold will continue to accumulate under the refrigeration damper 43. Once the section where the refrigeration damper 43 is located in the refrigeration air inlet duct 41 and the refrigeration liner 31 are assembled and air leaks due to low-temperature contraction, the cold in the freezer compartment 12 may penetrate into the refrigeration liner 31, resulting in the temperature of a local area in the refrigeration liner 31 being too low, causing local frost on food ingredients, which is not conducive to the user's refrigerator experience. In this way, by setting an environmental sensor 50 at the connection between the section where the refrigerated air door 43 is located and the refrigerated liner 31 in the refrigerated air inlet duct 41, the embodiment of the present disclosure can preferentially detect the environmental parameters of the refrigerated liner 31 near the refrigerated air door 43 where the probability of cold air leakage is higher, thereby facilitating more accurate identification of cold air leakage and timely resolution.

[0052] Optionally, the antifreeze fan 60 is arranged on the back side of the refrigerated drawer 70, and the air outlet direction is toward the refrigerated return air duct 42. In this way, the antifreeze fan 60 can blow away the accumulated cold air, thereby preventing the leaked cold air from blowing directly into the refrigerated drawer 70 to cause local frost on the food.

[0053] Optionally, the antifreeze fan 60 and the return air outlet of the refrigeration return air duct 42 are respectively arranged on both sides of the refrigeration air inlet duct 41. In this way, along with the rotation of the antifreeze fan 60, the leaked cold air can also circulate in the refrigeration compartment 11 along the tangent direction of the rotation of the fan blades of the antifreeze fan 60, so that the cold capacity of the leaked cold air can be fully utilized, so that the food in the non-leaking place can be refrigerated and preserved before being discharged through the refrigeration return air duct 42, which is conducive to improving the preservation effect of the food in the refrigeration compartment 11.

[0054] Combination Figure 3 As shown, the embodiment of the present disclosure provides a schematic diagram of cold air leakage in a refrigerated liner. The dotted line portion is the cold air leakage path. The refrigerated liner 31 and the refrigerated air inlet duct 41 are sealed by a sealing layer 33, but due to factors such as assembly and shrinkage, the assembly of the two is prone to flash seams, air leakage and the like. Especially at the connection between the refrigerated air inlet duct 41 and the bottom wall of the refrigerated liner 31, below it is the refrigeration area of ​​the freezer compartment 12, and the temperature therein is close to the low temperature of the freezer compartment 12. Under low temperature conditions, the foaming material in the sealing layer 33 and the plastic parts such as the refrigerated liner 31 will shrink to a certain extent, and after shrinkage, air leakage may occur in the sealing layer 33 area. And when the refrigerated air door 43 is closed, the cold in the freezer compartment 12 cannot be transferred to the refrigerated liner 31 through the refrigerated air inlet duct 41, but the cold will continue to accumulate below the refrigerated air door 43. Once air leakage occurs at the assembly point of the refrigerated liner 31 and the refrigerated air inlet duct 41 due to low-temperature contraction, the cold in the freezer compartment 12 may penetrate into the refrigerated liner 31, causing the temperature of a local area in the refrigerated liner 31 to be too low, causing local frost on food, which is not conducive to the user's refrigerator experience.

[0055] Combination Figure 4 As shown, the embodiment of the present disclosure provides a schematic diagram of an antifreeze fan exhausting leaked cold air. Among them, the dotted line portion is the exhaust path of the leaked cold air. When flash cracks, air leakage and other phenomena occur at the assembly point of the refrigerated liner 31 and the refrigerated air inlet duct 41, the cold will continue to accumulate at the cold air leakage point, causing the temperature in the local area to be too low, which may cause the food in the refrigerated drawer 70 at that location to be frozen. By running the antifreeze fan 60, the cold accumulated at the cold air leakage point can be blown away, thereby preventing the leaked cold air from blowing directly into the refrigerated drawer 70 and causing local frost on the food. On the one hand, the air outlet direction of the antifreeze fan 60 is toward the refrigerated return air duct 42, so that the leaked cold air can be discharged through the refrigerated return air duct 42, thereby preventing the cold from accumulating at the cold air leakage point, solving the problem of local frost on the food in the refrigerated liner 31. On the other hand, the tangential direction of the rotation of the antifreeze fan 60 blades can drive the cold to circulate in the refrigerated compartment 11, such as Figure 4As shown, the leaked cold air can be sent upward and to the left, and then enter the refrigerated return air duct 42 for discharge. This can ensure that the food in the bottom refrigerated drawer 70 will not be frozen, and can also improve the refrigeration effect of other refrigerated drawers 70 above. Therefore, the disclosed embodiment can improve the utilization rate of cold energy, which is conducive to improving the preservation effect of food in the refrigerated compartment 11.

[0056] Based on the above single system refrigerator, combined with Figure 5 As shown, the embodiment of the present disclosure provides a control method for a single-system refrigerator, comprising:

[0057] S501, the processor controls the environmental sensor to obtain environmental parameters at the connection between the refrigeration liner and the refrigeration air inlet duct.

[0058] S502, when the environmental parameters indicate that cold air has leaked in the refrigerated inner tank, the processor operates the antifreeze fan to discharge the leaked cold air through the refrigerated return air duct.

[0059] By adopting the control method for a single-system refrigerator provided by the embodiment of the present disclosure, the environmental parameters of the assembly area are collected by the environmental sensor provided at the connection between the refrigerated inner tank and the refrigerated air inlet duct, so that the cold air leakage in the refrigerated inner tank can be detected in real time. When flashing seams, air leakage and other phenomena occur at the assembly point of the refrigerated inner tank and the refrigerated air inlet duct, the embodiment of the present disclosure can identify the cold air leakage phenomenon that is occurring through abnormal environmental parameters, and discharge the leaked cold air through the refrigerated return air duct by running the antifreeze fan, so as to avoid the cold energy from accumulating at the cold air leakage point, and solve the problem of local frost on food in the refrigerated inner tank.

[0060] Optionally, the environmental parameters include the ambient temperature and / or the ambient wind speed. Thus, by detecting the above environmental parameters, the disclosed embodiment can analyze whether there are abnormal environmental parameters, and identify possible cold air leakage accordingly, thereby facilitating timely operation of the antifreeze fan to avoid cold energy accumulation at the cold air leakage location.

[0061] Optionally, the processor determines that cold air leakage occurs in the refrigerated liner in the following manner, including: the ambient temperature is less than or equal to the temperature threshold; and / or the ambient wind speed is greater than or equal to the wind speed threshold. In this way, when the ambient temperature at the connection between the refrigerated liner and the refrigerated air inlet duct is less than or equal to the temperature threshold, it indicates that the cold air in the freezer compartment may penetrate into the refrigerated liner, resulting in the temperature of the local area being too low. Therefore, the embodiment of the present disclosure can identify the cold air leakage phenomenon that is occurring by the abnormal temperature, so as to facilitate the timely operation of the antifreeze fan to prevent local food from frost. Similarly, when the ambient wind speed at the connection between the refrigerated liner and the refrigerated air inlet duct is greater than or equal to the wind speed threshold, it indicates that the cold air in the freezer compartment may penetrate into the refrigerated liner, resulting in the wind speed of the local area being too high. Therefore, the embodiment of the present disclosure can identify the cold air leakage phenomenon that is occurring by the abnormal wind speed, so as to facilitate the timely operation of the antifreeze fan to prevent local food from frost.

[0062] Optionally, the value range of the temperature threshold is [0°C, 4°C], and the temperature threshold can be set according to the opening and closing state of the refrigeration damper. If the refrigeration damper is closed, the refrigeration compartment cannot supplement the cold air delivered by the freezer compartment, and under the influence of the external environment, its internal temperature will rise slightly. Therefore, the embodiment of the present disclosure can set a slightly larger first temperature threshold to identify the cold air leaked to the refrigeration tank earlier, which is conducive to timely operation of the antifreeze fan to prevent local food frost. If the refrigeration damper is opened, the freezer compartment continues to transfer cold air to the refrigeration compartment, so the temperature inside the refrigeration compartment is low. Therefore, the embodiment of the present disclosure can set a slightly smaller second temperature threshold to avoid misidentifying the normal fluctuation of the refrigeration temperature in the refrigeration compartment as a cold air leakage phenomenon, which is conducive to preventing the antifreeze fan from starting by mistake. Preferably, the first temperature threshold is 1°C and the second temperature threshold is 0°C. The above temperature thresholds can also be adjusted according to the actual needs of the user, and can also be set to any other value such as 0.5°C or 2°C.

[0063] Optionally, the value range of the wind speed threshold is [0.1m / s, 1m / s], and the wind speed threshold can be set according to the opening and closing state of the refrigeration damper. If the refrigeration damper is closed, the cold air delivered to the refrigeration compartment by the refrigeration fan cannot enter the refrigeration tank, so the environmental sensor cannot identify the cold air circulation corresponding to normal refrigeration, and can only identify the cold air circulation corresponding to the sinking of cold air. Therefore, the embodiment of the present disclosure can set a slightly smaller first wind speed threshold to accurately identify the cold air circulation caused by cold air leakage other than the sinking of cold air, which is conducive to timely operation of the antifreeze fan to prevent local food frost. If the refrigeration damper is opened, the freezing compartment delivers cold air to the refrigeration compartment through the refrigeration fan and enters the refrigeration tank. The environmental sensor can collect the cold air circulation corresponding to normal refrigeration, and the wind speed of this part of the cold air circulation is relatively large. Therefore, the embodiment of the present disclosure can set a slightly larger second wind speed threshold to avoid misidentifying the cold air circulation corresponding to normal refrigeration and the sinking of cold air as a cold air leakage phenomenon, which is conducive to preventing the antifreeze fan from being started by mistake. Preferably, the first wind speed threshold is 0.2 m / s, and the second wind speed threshold is 0.6 m / s. The above wind speed thresholds can also be adjusted according to actual user needs, and can also be set to any other value such as 0.1 m / s or 0.5 m / s.

[0064] Optionally, the processor runs the antifreeze fan, including: the processor determines the target speed of the antifreeze fan according to the environmental parameters; the processor controls the antifreeze fan to run according to the target speed. In this way, the disclosed embodiment can judge the actual working condition of the cold air leakage in combination with the environmental parameters at the connection between the refrigerated inner tank and the refrigerated air inlet duct, and then match the appropriate antifreeze fan speed according to the leakage degree to ensure the efficiency of the antifreeze fan in exhausting the leaked cold air. This can more reliably avoid the cold energy from accumulating at the cold air leakage point, which is conducive to preventing the local frost of the food in the refrigerated inner tank.

[0065] Optionally, the processor determines the target speed of the antifreeze fan according to the environmental parameters, including: the processor determines the target speed of the antifreeze fan according to the ambient temperature; and / or the processor determines the target speed of the antifreeze fan according to the ambient wind speed. In this way, the disclosed embodiment can judge the actual working condition of the cold air leakage in combination with the ambient temperature and / or ambient wind speed at the connection between the refrigerated inner tank and the refrigerated air inlet duct, and then match the appropriate antifreeze fan speed according to the leakage degree to ensure the efficiency of the antifreeze fan in exhausting the leaked cold air. This can more reliably avoid the accumulation of cold energy at the cold air leakage point, which is conducive to preventing local frost on food in the refrigerated inner tank.

[0066] Optionally, the processor determines the target speed of the antifreeze fan according to the ambient temperature, including: when the ambient temperature continues to drop, the processor determines the target speed of the antifreeze fan to be a first speed; or, when the ambient temperature continues to rise, the processor determines the target speed of the antifreeze fan to be a second speed. Wherein, the first speed is greater than the second speed. In this way, the embodiment of the present disclosure can judge the actual working condition of the cold air leakage in combination with the change of the ambient temperature at the connection between the refrigerated inner tank and the refrigerated air inlet duct, and then match the appropriate antifreeze fan speed according to the leakage degree to ensure the efficiency of the antifreeze fan in discharging the leaked cold air. Specifically, when the ambient temperature continues to drop, it indicates that the cold in the freezer compartment may penetrate into the refrigerated inner tank and gather at the place where the cold air leaks, thereby causing the local temperature to continue to drop. Therefore, the embodiment of the present disclosure sets the target speed of the antifreeze fan to a relatively high first speed, which can suppress the trend of the temperature drop at the place where the cold air leaks by operating the fan at a high speed, thereby helping to avoid the leaked cold air blowing directly into the refrigerated drawer and causing local food frost. When the ambient temperature continues to rise, it indicates that the cold in the freezer compartment has not leaked into the refrigerated inner tank, or the antifreeze fan has suppressed the temperature drop trend at the place where the cold air leaked. Therefore, the disclosed embodiment sets the target speed of the antifreeze fan to a relatively low second speed, which can ensure that the temperature of the bottom refrigerated drawer can quickly recover by appropriately reducing the fan speed, so as to avoid frost on food caused by low temperature in a local area.

[0067] Optionally, the processor determines the target speed of the antifreeze fan according to the ambient wind speed, including: when the ambient wind speed is greater than or equal to the preset wind speed, the processor determines the target speed of the antifreeze fan to be the third speed; or, when the ambient wind speed is less than the preset wind speed, the processor determines the target speed of the antifreeze fan to be the fourth speed. Wherein, the third speed is greater than the fourth speed. In this way, the embodiment of the present disclosure can judge the actual working condition of the cold air leakage by combining the relationship between the ambient wind speed and the preset wind speed at the connection between the refrigerated inner tank and the refrigerated air inlet duct, and then match the appropriate antifreeze fan speed according to the leakage degree to ensure the efficiency of the antifreeze fan in discharging the leaked cold air. Specifically, when the ambient wind speed is greater than or equal to the preset wind speed, it indicates that the cold amount in the freezer room penetrates into the refrigerated inner tank, and the leakage degree is high, which is easy to cause the temperature in the local area to be too low, thereby causing local food frost. Therefore, the embodiment of the present disclosure sets the target speed of the antifreeze fan to a relatively high third speed, which can improve the efficiency of discharging the leaked cold air by running the fan at a high speed, thereby helping to avoid the leaked cold air blowing directly into the refrigerated drawer and causing local food frost. When the ambient wind speed is lower than the preset wind speed, it indicates that although the cold in the freezer has penetrated into the refrigerated inner tank, the leakage is low and it takes a long time for the cold to accumulate before local food frost occurs. Therefore, the disclosed embodiment sets the target speed of the antifreeze fan to a relatively low fourth speed, which can appropriately reduce the fan speed, while ensuring that the bottom refrigerated drawer will not frost the food, and can also improve the energy saving benefits of the single-system refrigerator.

[0068] Optionally, the preset wind speed is greater than the wind speed threshold, and the preset wind speed can be set according to the opening and closing state of the refrigeration damper. When the refrigeration damper is closed, the embodiment of the present disclosure can set a slightly smaller first preset wind speed to accurately identify the cold air circulation caused by cold air leakage other than cold air sinking, which is conducive to timely operation of the antifreeze fan to prevent local food frost. When the refrigeration damper is closed, the embodiment of the present disclosure can set a slightly larger second preset wind speed to avoid misidentifying the cold air circulation corresponding to normal refrigeration and cold air sinking as a cold air leakage phenomenon, which is conducive to preventing the antifreeze fan from being mistakenly started. Preferably, the first preset wind speed is 0.4m / s, and the second preset wind speed is 0.8m / s. The above preset wind speeds can also be adjusted according to the actual needs of the user, and can also be set to any other reasonable values ​​such as 0.5m / s or 0.9m / s.

[0069] Based on the above single system refrigerator, combined with Figure 6 As shown, the embodiment of the present disclosure provides another control method for a single-system refrigerator, comprising:

[0070] S601, the processor controls the environmental sensor to obtain environmental parameters at the connection between the refrigeration liner and the refrigeration air inlet duct.

[0071] S602: When the ambient temperature is less than or equal to the temperature threshold, the processor determines a target rotation speed of the antifreeze fan according to the ambient wind speed.

[0072] S603, the processor controls the antifreeze fan to run at a target speed to discharge the leaked cold air through the refrigeration return air duct.

[0073] The control method for a single-system refrigerator provided by the embodiment of the present disclosure is adopted, and the environmental parameters of the assembly area are collected by the environmental sensor provided at the connection between the refrigerated inner tank and the refrigerated air inlet duct, so that the cold air leakage in the refrigerated inner tank can be detected in real time. When the ambient temperature at the connection between the refrigerated inner tank and the refrigerated air inlet duct is less than or equal to the temperature threshold, it indicates that the assembly of the refrigerated inner tank and the refrigerated air inlet duct may have flash seams, air leakage and the like, resulting in the cold in the freezer room penetrating into the refrigerated inner tank, causing the temperature of the local area to be too low. Based on this, the embodiment of the present disclosure runs the antifreeze fan to discharge the leaked cold air through the refrigerated return air duct, so as to avoid the cold air from accumulating at the cold air leakage point, and solves the problem of local food frost in the refrigerated inner tank. And the embodiment of the present disclosure further combines the ambient wind speed at the connection between the refrigerated inner tank and the refrigerated air inlet duct to judge the actual working condition of the cold air leakage, so as to match the appropriate antifreeze fan speed according to the specific leakage degree, which is conducive to ensuring the efficiency of the antifreeze fan to discharge the leaked cold air, so as to better prevent local food frost.

[0074] Based on the above single system refrigerator, combined with Figure 7 As shown, the embodiment of the present disclosure provides another control method for a single-system refrigerator, comprising:

[0075] S701, the processor controls the environmental sensor to obtain environmental parameters at the connection between the refrigeration liner and the refrigeration air inlet duct.

[0076] S702, when the environmental parameters indicate that cold air leakage occurs in the refrigeration tank, if the refrigeration damper is open, the processor closes the refrigeration damper.

[0077] S703: The processor operates the antifreeze fan to discharge the leaked cold air through the refrigeration return air duct.

[0078] By adopting the control method for a single-system refrigerator provided by the embodiment of the present disclosure, the environmental parameters of the assembly area are collected by the environmental sensor provided at the connection between the refrigerated inner tank and the refrigerated air inlet duct, so that the cold air leakage in the refrigerated inner tank can be detected in real time. When flashing seams, air leakage and other phenomena occur at the assembly point of the refrigerated inner tank and the refrigerated air inlet duct, the embodiment of the present disclosure can identify the cold air leakage phenomenon that is occurring through abnormal environmental parameters, and preferentially confirm the open and closed state of the refrigerated air door when the cold air leaks, and immediately close the refrigerated air door if it is open, so as to avoid excessive cold entering the refrigerated inner tank and causing frost on the food stored inside. Then, the leaked cold air is discharged through the refrigerated return air duct by running the antifreeze fan, so as to avoid the cold air from accumulating at the cold air leakage point, solving the problem of local frost on the food in the refrigerated inner tank.

[0079] Based on the above single system refrigerator, combined with Figure 8 As shown, the embodiment of the present disclosure provides another control method for a single-system refrigerator, comprising:

[0080] S801, the processor controls the environmental sensor to obtain environmental parameters at the connection between the refrigeration liner and the refrigeration air inlet duct.

[0081] S802, when the environmental parameters indicate that cold air has leaked in the refrigerated tank, the processor operates the antifreeze fan to discharge the leaked cold air through the refrigerated return air duct.

[0082] S803: The processor collects the duration of the cold air leakage.

[0083] S804: When the duration of the cold air leakage is greater than or equal to the first preset duration, the processor controls the refrigerated drawer to move away from the refrigerated air inlet duct.

[0084] The control method for a single-system refrigerator provided by the embodiment of the present disclosure is adopted, and the environmental parameters of the assembly area are collected by the environmental sensor provided at the connection between the refrigerated inner tank and the refrigerated air inlet duct, so that the cold air leakage in the refrigerated inner tank can be detected in real time. When the assembly of the refrigerated inner tank and the refrigerated air inlet duct has flashing seams, air leakage and the like, the embodiment of the present disclosure can identify the cold air leakage phenomenon that is occurring through abnormal environmental parameters, and discharge the leaked cold air through the refrigerated return air duct by running the antifreeze fan, so as to avoid the cold energy from accumulating at the cold air leakage place, and solve the problem of local food frost in the refrigerated inner tank. In addition, after running the antifreeze fan, the embodiment of the present disclosure collects the duration of the cold air leakage. If the duration is greater than or equal to the first preset duration, it indicates that the environmental parameters at the connection between the refrigerated inner tank and the refrigerated air inlet duct have not been effectively improved, and running the antifreeze fan is not enough to cope with the current cold air leakage. Then the embodiment of the present disclosure controls the refrigerated drawer to move away from the refrigerated air inlet duct, so that the distance between it and the cold air leakage place increases, so as to reduce the speed of frost of the food stored inside it. Moreover, as the distance between the refrigerated drawer and the refrigerated air inlet duct increases, the wind circulation of the antifreeze fan at that location increases, which is conducive to discharging the leaked cold air faster, thereby further improving its antifreeze effect.

[0085] Optionally, the value range of the first preset time is [1min, 10min]. Preferably, the first preset time is 3min. The first preset time can also be adjusted in combination with the operating conditions of the single-system refrigerator, and can also be set to any other reasonable value such as 2min or 5min.

[0086] Based on the above single system refrigerator, combined with Fig. 9 As shown, the embodiment of the present disclosure provides another control method for a single-system refrigerator, comprising:

[0087] S901, the processor controls the environmental sensor to obtain environmental parameters at the connection between the refrigeration liner and the refrigeration air inlet duct.

[0088] S902, when the environmental parameters indicate that cold air has leaked from the refrigeration tank, the processor operates the antifreeze fan to discharge the leaked cold air through the refrigeration return air duct.

[0089] S903: The processor collects the duration of the cold air leakage.

[0090] S904: When the duration of the cold air leakage is greater than or equal to the second preset duration, the processor controls the compressor and / or the refrigeration fan to stop running.

[0091] The control method for a single-system refrigerator provided by the embodiment of the present disclosure is adopted, and the environmental parameters of the assembly area are collected by the environmental sensor provided at the connection between the refrigerated inner tank and the refrigerated air inlet duct, so that the cold air leakage in the refrigerated inner tank can be detected in real time. When flashing, air leakage and other phenomena occur at the assembly point of the refrigerated inner tank and the refrigerated air inlet duct, the embodiment of the present disclosure can identify the cold air leakage phenomenon that is occurring through abnormal environmental parameters, and discharge the leaked cold air through the refrigerated return air duct by running the antifreeze fan, so as to avoid the cold energy from accumulating at the cold air leakage point, and solve the problem of local frost on the food in the refrigerated inner tank. In addition, after running the antifreeze fan, the embodiment of the present disclosure collects the duration of the cold air leakage. If the duration is greater than or equal to the second preset duration, it indicates that the environmental parameters at the connection between the refrigerated inner tank and the refrigerated air inlet duct have not been effectively improved, and running the antifreeze fan is not enough to deal with the current cold air leakage situation. The disclosed embodiment controls the compressor and / or the refrigeration fan to stop running, so that the refrigeration system stops generating or transmitting cold energy, thereby cutting off the source of cold energy leakage, so as to effectively prevent excessive cold energy from penetrating into the refrigeration tank and causing local frost on food.

[0092] Optionally, the second preset time length is greater than the first preset time length. In this way, when running the antifreeze fan is not enough to cope with the current cold air leakage, the disclosed embodiment can take the measure of moving the refrigerated drawer forward as a priority to cope with the strong cold air leakage, thereby ensuring the normal refrigeration operation of the freezer compartment to ensure the freezing effect of the food stored therein. If it is still not enough to improve the environmental parameters at the connection between the refrigerated liner and the refrigerated air inlet duct, further measures are taken to shut down the compressor and / or the refrigeration fan to prevent local frost on the food in the refrigerated compartment by cutting off the source of the leaked cold air.

[0093] Optionally, the second preset time length has a value range of [2min, 20min]. Preferably, the second preset time length is 6min. The second preset time length can also be adjusted in combination with the operating conditions of the single-system refrigerator, and can also be set to any other reasonable value such as 4min or 10min.
