[0001] The present application relates to the technical field of refrigerators, and in particular to a refrigerator control method and device, a refrigerator apparatus, and a storage medium. BACKGROUND

[0002] With the popularization of refrigerators in the consumer market and the gradual improvement of people's living standards, more and more consumers have higher requirements for the preservation of food. The temperature control range of the freezing chamber of most refrigerators on the market is generally -24℃ to -16℃, which cannot meet the requirements of ultra-low temperature preservation of food. To meet the needs of users, refrigerators with deep freezing functions have appeared on the market, which can further reduce the temperature of the freezing chamber and achieve ultra-low temperature preservation effects of -26℃ or even lower. However, such refrigerators are easily affected by defrosting temperature under the ultra-low temperature preservation function, resulting in large fluctuations in the temperature of the freezing chamber and failing to meet the requirements of long-term stable ultra-low temperature preservation of food. SUMMARY

[0003] The present application provides a refrigerator control method, device, apparatus, and storage medium to solve the problem that existing refrigerators cannot stably preserve food at ultra-low temperature for a long time.

[0004] In a first aspect, the present application provides a refrigerator control method, which comprises:

[0005] When the deep freezing function is turned on, the refrigerator is controlled to operate in a first refrigeration mode, wherein the parameters adjusted by the first refrigeration mode include a pre-refrigeration temperature and a first refrigeration time length for reducing the temperature of the freezing chamber of the refrigerator;

[0006] When the refrigerator operates for the first refrigeration time length, the refrigerator is controlled to operate in a preset defrosting mode, and the operating parameters of the refrigerator are collected in real time;

[0007] When the operating parameters of the refrigerator meet the exit condition of the preset defrosting mode, the refrigerator is controlled to exit the preset defrosting mode and operate in a second refrigeration mode, wherein the parameters adjusted by the second refrigeration mode include a deep freezing refrigeration temperature for reducing the temperature of the freezing chamber, and the deep freezing refrigeration temperature is lower than the pre-refrigeration temperature;

[0008] When the refrigerator operates in the second refrigeration mode until the temperature of the freezing chamber is less than or equal to the deep freezing refrigeration temperature, and the operating parameters of the compressor of the refrigerator meet a preset defrosting condition, the step of controlling the refrigerator to operate in the preset defrosting mode until the operating parameters of the refrigerator meet the exit condition of the preset defrosting mode, and then controlling the refrigerator to exit the preset defrosting mode and operate in the second refrigeration mode is performed.

[0009] In a second aspect, the application provides a refrigerator control device, the device comprising:

[0010] a pre-cooling module configured to control the refrigerator to operate in a first cooling mode when a deep-freezing function is turned on, wherein the first cooling mode adjusts parameters including a pre-cooling temperature for lowering a temperature of a freezer compartment of the refrigerator and a first cooling duration;

[0011] a defrosting module configured to control the refrigerator to operate in a preset defrosting mode when the first cooling duration ends, and collect operation parameters of the refrigerator in real time;

[0012] a deep-freezing module configured to control the refrigerator to exit the preset defrosting mode and operate in a second cooling mode when the operation parameters of the refrigerator meet an exit condition of the preset defrosting mode, wherein the second cooling mode adjusts parameters including a deep-freezing cooling temperature for lowering the temperature of the freezer compartment, and the deep-freezing cooling temperature is lower than the pre-cooling temperature;

[0013] a cycle module configured to execute the step of controlling the refrigerator to operate in the preset defrosting mode until the operation parameters of the refrigerator meet the exit condition of the preset defrosting mode, and then control the refrigerator to exit the preset defrosting mode and operate in the second cooling mode when the refrigerator operates in the second cooling mode until the temperature of the freezer compartment is less than or equal to the deep-freezing cooling temperature, and operation parameters of a compressor of the refrigerator meet a preset defrosting condition.

[0014] In a third aspect, the application provides a refrigerator device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the method in the first aspect.

[0015] In a fourth aspect, the application further provides a computer storage medium storing computer executable instructions for executing the refrigerator control method in the first aspect.

[0016] Compared with the prior art, the method provided in the embodiments of the present application has the following advantages: when the deep-freezing function is turned on, the refrigerator is controlled to operate in a first refrigeration mode, wherein the parameters adjusted by the first refrigeration mode include a pre-refrigeration temperature and a first refrigeration time length for reducing the temperature of the freezer compartment of the refrigerator, that is, the refrigerator is controlled to perform pre-refrigeration before defrosting, which can reduce the temperature difference between before and after defrosting. When the operation of the refrigerator in the first refrigeration mode ends, the refrigerator is controlled to operate in a preset defrosting mode, and the operating parameters of the refrigerator are collected in real time. After the pre-refrigeration of the refrigerator ends, defrosting is performed once, so as to avoid the adverse effects of frosting in this stage on the subsequent deep-freezing effect of the refrigerator. When the operating parameters of the refrigerator meet the exit condition of the preset defrosting mode, the refrigerator is controlled to exit the preset defrosting mode and operate in a second refrigeration mode, wherein the parameters adjusted by the second refrigeration mode include a deep-freezing refrigeration temperature for reducing the temperature of the freezer compartment, and the deep-freezing refrigeration temperature is lower than the pre-refrigeration temperature. That is, after defrosting ends, the refrigerator is controlled to perform deep-freezing treatment at the deep-freezing refrigeration temperature. Since the refrigerator has undergone defrosting once before, the deep-freezing effect of the refrigerator can be ensured. When the temperature of the freezer compartment is less than or equal to the deep-freezing refrigeration temperature and the operating parameters of the compressor of the refrigerator meet the preset defrosting condition, the step of controlling the refrigerator to operate in the preset defrosting mode until the operating parameters of the refrigerator meet the exit condition of the preset defrosting mode and then controlling the refrigerator to exit the preset defrosting mode and operate in the second refrigeration mode is performed, which means that the frosting condition in the freezer compartment is determined based on the operating parameters of the compressor when the temperature of the freezer compartment is less than or equal to the deep-freezing refrigeration temperature. When the frosting condition meets the preset defrosting condition, defrosting is performed again. Since defrosting is performed once before deep-freezing, the amount of defrosting after deep-freezing is reduced. In addition, defrosting is performed when the temperature of the freezer compartment is less than or equal to the deep-freezing refrigeration temperature, which can reduce the influence of the temperature rise caused by defrosting on the temperature of the freezer compartment. Therefore, the temperature of the freezer compartment of the refrigerator can be stably maintained near the deep-freezing refrigeration temperature for a long time, and the effect of stably storing food at an ultra-low temperature for a long time can be achieved.

[0032] Figure 1 FIG. 1 is a diagram of an application environment of a refrigerator control method according to an embodiment of the present application. Referring to FIG. 1, the refrigerator control method is applied to a refrigerator control system. The refrigerator control system includes a refrigerator 110 and a refrigerator control device 120. The refrigerator 110 and the refrigerator control device 120 can be integrally provided or separately provided. In the present embodiment, the refrigerator 110 and the refrigerator control device 120 are integrally provided. Figure 1

[0033] In one embodiment, the refrigerator control method includes the following steps. Figure 2 FIG. 2 is a flowchart of a refrigerator control method according to an embodiment of the present application. Referring to FIG. 2, a refrigerator control method is provided. The present embodiment mainly illustrates the method applied to the terminal control device 120 in the refrigerator control system described above with reference to FIG. 1. The refrigerator control method includes the following steps. Figure 2 Figure 1

[0034] Step S210, when the deep-freezing function is turned on, controlling the refrigerator 110 to operate in a first refrigeration mode, wherein the parameters adjusted by the first refrigeration mode include a pre-refrigeration temperature for lowering the temperature of the freezer compartment of the refrigerator 110 and a first refrigeration time length.

[0035] Specifically, when the deep-freezing function is turned off, the refrigerator 110 operates in a preset refrigeration mode. The refrigeration temperature of the preset refrigeration mode is higher than the refrigeration temperature corresponding to the deep-freezing function. The preset refrigeration mode can be a default refrigeration mode of the refrigerator 110 or a refrigeration mode customized by a user. The turning on of the deep-freezing function can be triggered by a user manually operating the operation panel of the refrigerator 110, for example, the user lighting up the deep-freezing icon in the operation panel of the refrigerator 110, or triggered by the user remotely transmitting a deep-freezing function turning-on command to the refrigerator 110 through a terminal, or triggered by a voice command or a gesture command initiated by the user. When the deep-freezing function is turned on, the refrigerator 110 is first controlled to operate in a first refrigeration mode for pre-refrigeration, and the temperature of the freezer compartment of the refrigerator 110 is first lowered according to the pre-refrigeration temperature.

[0036] Step S220, when the refrigerator 110 operates for the first refrigeration time length, controlling the refrigerator 110 to operate in a preset defrosting mode and collecting the operating parameters of the refrigerator 110 in real time. ​​​

[0037] Specifically, after the first refrigeration duration ends, the refrigerator 110 is controlled to run according to the preset defrosting mode, that is, the refrigerator 110 defrosts the freezer compartment. Since the freezer compartment is pre-cooled before defrosting, the temperature difference before and after this defrosting can be ensured not to be too large, that is, the temperature of the freezer compartment after defrosting is effectively prevented from rising too much, the influence of defrosting on the temperature fluctuation of the freezer compartment can be reduced, the uniformity and stability of the temperature of the freezer compartment are ensured, and the defrosting in this stage is beneficial to the long-time ultra-low temperature refrigeration in the next stage.

[0038] Step S230: When the operating parameters of the refrigerator 110 meet the exit condition of the preset defrosting mode, the refrigerator 110 is controlled to exit the preset defrosting mode and run according to a second refrigeration mode, wherein the parameters adjusted by the second refrigeration mode include a deep-freezing refrigeration temperature for reducing the temperature of the freezer compartment, and the deep-freezing refrigeration temperature is lower than the pre-cooling temperature.

[0039] Specifically, the operating parameters of the refrigerator 110 include the operating parameters of various devices in the refrigerator 110, and the devices in the refrigerator 110 specifically include an evaporator in the freezer compartment, a temperature sensor on the evaporator, a temperature sensor in the freezer compartment, a compressor, a defrosting heater, and the like. When the operating parameters of the refrigerator 110 meet the exit condition of the preset defrosting mode, the refrigerator 110 is controlled to exit the preset defrosting mode and run according to a second refrigeration mode, that is, the refrigerator 110 is controlled to reduce the temperature of the freezer compartment according to the deep-freezing refrigeration temperature to achieve ultra-low temperature preservation, and the deep-freezing refrigeration temperature is lower than the pre-cooling temperature. Since the refrigerator 110 is pre-cooled and defrosted before deep-freezing, the amount of frost in this stage is reduced, and thus the ultra-low temperature freezing effect in this stage can be ensured, that is, the influence of the amount of frost on the deep-freezing effect in this stage is reduced.

[0040] Step S240: When the refrigerator 110 runs according to the second refrigeration mode until the temperature of the freezer compartment is less than or equal to the deep-freezing refrigeration temperature, and the operating parameters of the compressor in the refrigerator 110 meet the preset defrosting condition, the step of controlling the refrigerator 110 to run according to the preset defrosting mode until the operating parameters of the refrigerator 110 meet the exit condition of the preset defrosting mode, and then controlling the refrigerator 110 to exit the preset defrosting mode and run according to the second refrigeration mode is performed.

[0041] Specifically, when the refrigerator 110 operates in the second refrigeration mode until the freezing chamber temperature is less than or equal to the deep-freezing refrigeration temperature, and the operating parameter of the compressor meets the preset defrosting condition, the refrigerator 110 is controlled to perform defrosting treatment in the preset defrosting mode again. When the freezing chamber temperature reaches or is lower than the deep-freezing refrigeration temperature, the frosting condition in the freezing chamber is judged based on the operating parameter of the compressor, and defrosting treatment is performed again when the frosting condition meets the preset defrosting condition. Since the defrosting treatment is performed once before deep-freezing, the amount of defrosting after deep-freezing is reduced, and defrosting is performed based on the freezing chamber temperature being less than or equal to the deep-freezing refrigeration temperature, which can reduce the influence of defrosting temperature rise on the freezing chamber temperature. After this defrosting, the refrigerator 110 is controlled to exit the preset defrosting mode and operate in the second refrigeration mode when the operating parameter of the refrigerator 110 meets the exit condition of the preset defrosting mode. The second refrigeration mode and the preset defrosting mode are alternately cycled to reduce the amount of frosting in the freezing chamber while ensuring ultra-low temperature, so as not to affect the ultra-low temperature refrigeration effect after defrosting, and to ensure that the freezing chamber temperature of the refrigerator 110 is stable near the deep-freezing refrigeration temperature for a long time, achieving the effect of long-time stable ultra-low temperature food preservation.

[0042] In one embodiment, when the deep-freezing function is turned on, the refrigerator 110 is controlled to operate in the first refrigeration mode, comprising:

[0043] When the deep-freezing function is turned on, the current environment temperature and the freezing evaporator temperature are obtained.

[0044] The comparison result between the current environment temperature and the first preset temperature corresponds to the compressor speed gear as the first operating gear, and the first refrigeration mode further comprises the first operating gear.

[0045] The temperature difference between the pre-refrigeration temperature and the freezing evaporator temperature is compared with the second preset temperature, and the comparison result corresponds to the compressor operating time as the first refrigeration time.

[0046] The compressor in the refrigerator 110 is controlled to operate in the first operating gear and the first refrigeration time.

[0047] Specifically, as Figure 3As shown, when the deep-freezing function is turned on, the current ambient temperature Th and the freezing evaporator temperature Tzf are obtained, the freezing evaporator temperature refers to the temperature collected by the temperature sensor on the evaporator, the current ambient temperature is compared with the first preset temperature, that is, whether the current ambient temperature is greater than or equal to the first preset temperature is judged, the first preset temperature is denoted as a1, and the first preset temperature can be customized according to different application scenarios, in this embodiment, the value range of the first preset temperature is 28℃≤a1≤32℃, and the preferred value is 30℃. The comparison result between the current ambient temperature and the first preset temperature is used as the first running gear of the compressor, which specifically includes: when the current ambient temperature is greater than or equal to the first preset temperature, that is, Th≥a1, the second speed gear S2 is used as the first running gear; when the current ambient temperature is less than the first preset temperature, that is, Th

[0048] The temperature difference between the pre-cooling temperature and the freezing evaporator temperature is compared with the second preset temperature, and the comparison result is used as the first refrigeration time, which specifically includes: the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is compared with the second preset temperature, that is, whether the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is greater than the second preset temperature is judged, the pre-cooling temperature is denoted as Tsd, and the second preset temperature is denoted as a2, the pre-cooling temperature and the second preset temperature can be customized according to different application scenarios, in this embodiment, the pre-cooling temperature is-18℃, and the value range of the second preset temperature is 2℃≤a2≤4℃, and the preferred value is 3℃. Whether the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is greater than the second preset temperature, that is, whether Tsd-a2≤Tzf is established, on the basis of Tsd being-18℃ and a2 being 3℃, here Tzf ≥ -21℃ is established.

[0049] When the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is less than or equal to the second preset temperature, that is, Tsd-Tzf≤a2, for example, Tzf ≥-21℃, indicating that the freezing evaporator temperature is relatively close to the pre-cooling temperature, in order to make the freezing evaporator temperature further lower than the pre-cooling temperature so that the temperature after defrosting can still be kept near the pre-cooling temperature, ensuring that the freezing chamber temperature does not fluctuate greatly before and after defrosting, the compressor needs to provide more refrigeration capacity, then the first time threshold t3 is used as the first refrigeration time; when the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is greater than the second preset temperature, that is, Tsd-Tzf>a2, for example, Tzf<-21℃, indicating that the freezing evaporator temperature has been greatly lower than the pre-cooling temperature, and the compressor does not need to provide more refrigeration capacity, then the second time threshold t4 is used as the first refrigeration time, wherein the first time threshold is greater than the second time threshold, in the embodiment, the value range of the first time threshold t3 is 55≤t3≤65, and the preferred value is 60, the value range of the second time threshold t4 is 25≤t4≤35, and the preferred value is 30, the unit is min.

[0050] The compressor in the refrigerator 110 is controlled to pre-cool according to the first operating gear and the first refrigeration time, and the freezing chamber temperature of the refrigerator 110 is lowered to below the pre-cooling temperature and differs from the pre-cooling temperature by a certain temperature before defrosting.

[0051] In one embodiment, before the current environment temperature and the freezing evaporator temperature are obtained, the method further comprises:

[0052] A first timing duration is obtained, wherein the first timing duration is used to indicate the time interval from the last time the refrigerator 110 executes the pre-set defrosting mode;

[0053] When the first timing duration is greater than or equal to a first preset duration, the step of obtaining the current environment temperature and the freezing evaporator temperature is performed.

[0054] Specifically, when the deep-freezing function is turned on, the refrigerator 110 still maintains the current operating mode to continue running, and a first timing duration tps is obtained, which is used to indicate the time interval from the last time the pre-set defrosting mode is run. When the first timing duration is greater than or equal to a first preset duration t1, the current environment temperature and the freezing evaporator temperature are obtained, and then the subsequent steps are performed. The first preset duration is used to indicate a pre-set time interval for allowing defrosting. Only when a sufficient time has elapsed since the last defrosting, the subsequent first refrigeration mode and pre-set defrosting mode are executed, thereby effectively avoiding excessive defrosting frequency causing large temperature fluctuations in the freezing chamber. In the embodiment, the value range of the first preset duration is 5≤t1≤7, and the preferred value is 6, the unit is h. When the first timing duration is less than the first preset duration, the subsequent first refrigeration mode and pre-set defrosting mode are not executed, but the current operating mode is continued to refrigerate, thereby avoiding repeated temperature rise in the freezing chamber, and the above step of obtaining the first timing duration is repeatedly executed.

[0055] In one embodiment, the control of the refrigerator 110 according to the preset defrosting mode comprises:

[0056] Turning on the defrosting heater in the refrigerator 110, resetting the first timing duration for re-timing, and timing the opening duration of the defrosting heater;

[0057] When the operating parameters of the refrigerator 110 meet the exit condition of the preset defrosting mode, the control of the refrigerator 110 exiting the preset defrosting mode and operating according to a second refrigeration mode comprises:

[0058] When the opening duration of the defrosting heater reaches a preset heating duration, and / or the temperature of the freezing evaporator in the refrigerator 110 reaches a preset exit temperature, the defrosting heater is turned off, and it is determined whether the freezing chamber temperature is greater than the deep-freezing refrigeration temperature, wherein the operating parameters include the opening duration of the defrosting heater and the temperature of the freezing evaporator;

[0059] When the freezing chamber temperature is greater than the deep-freezing refrigeration temperature, the compressor in the refrigerator 110 is turned on;

[0060] The compressor speed gear corresponding to the temperature interval to which the freezing chamber temperature belongs is taken as a second operating gear, and the control of the compressor operating according to the second operating gear, wherein the second refrigeration mode further comprises the second operating gear for controlling the operation of the compressor.

[0061] Specifically, when the refrigerator 110 operates according to the preset defrosting mode, the defrosting heater in the refrigerator 110 is first turned on to heat the evaporator, and the first timing duration is reset for re-timing when the preset defrosting mode is entered, and the opening duration of the defrosting heater is timed.

[0062] When the opening duration of the defrosting heater reaches a preset heating duration and / or the temperature of the freezing evaporator reaches a preset exit temperature, it indicates that the defrosting is completed, then the defrosting heater is turned off, and it is determined whether the freezing chamber temperature is greater than the deep-freezing refrigeration temperature, the freezing chamber temperature is recorded as Td, and the deep-freezing refrigeration temperature is recorded as a3, in this embodiment, the value range of the deep-freezing refrigeration temperature is -36℃≤a3≤-38℃, and the preferred value is -37℃. If the freezing chamber temperature is lower than or equal to the deep-freezing refrigeration temperature, i.e. Td≤a3, it indicates that the freezing chamber temperature remains at or below the deep-freezing refrigeration temperature after defrosting, and the compressor does not need to operate for refrigeration, so the working state of the compressor is stopped.

[0063] As Figure 4As shown, if the freezing chamber temperature is greater than the deep-freezing refrigeration temperature and is in the refrigeration phase, i.e., Td>a3, it indicates that the freezing chamber temperature is warmed up to above the deep-freezing refrigeration temperature after defrosting, and in order to continue to maintain the ultra-low temperature preservation of the deep-freezing function, the compressor needs to be started to continue to provide refrigeration capacity to make the freezing chamber temperature reach or be lower than the deep-freezing refrigeration temperature. The compressor speed gear corresponding to the temperature interval to which the freezing chamber temperature belongs is taken as the second running gear, specifically including: if the freezing chamber temperature is located in the first temperature interval, it indicates that the temperature difference between the freezing chamber temperature and the deep-freezing refrigeration temperature is small, and the ultra-low temperature refrigeration capacity required to reduce the freezing chamber temperature to the deep-freezing refrigeration temperature is small, then the third speed gear S3 is taken as the second running gear, the speed corresponding to the third speed gear is greater than the speed corresponding to the second speed gear, and in the embodiment, the first temperature interval is (a3, a4], a4 is a fourth preset temperature, the value range of the fourth preset temperature is -33℃≤a4≤-31℃, and the preferred value is -32℃.

[0064] If the freezing chamber temperature is located in the second temperature interval, it indicates that the temperature difference between the freezing chamber temperature and the deep-freezing refrigeration temperature is large, and the ultra-low temperature refrigeration capacity required to reduce the freezing chamber temperature to the deep-freezing refrigeration temperature is large, then the fourth speed gear S4 is taken as the second running gear, the speed corresponding to the fourth speed gear is greater than the speed corresponding to the third speed gear, and in the embodiment, the second temperature interval is (a4, a5], a5 is a fifth preset temperature, the value range of the fifth preset temperature is -28℃≤a4≤-26℃, and the preferred value is -27℃.

[0065] If the freezing chamber temperature is located in the third temperature interval, it indicates that the temperature difference between the freezing chamber temperature and the deep-freezing refrigeration temperature is large, and in order to quickly reduce the freezing chamber temperature to the deep-freezing refrigeration temperature, the fifth speed gear S5 is taken as the second running gear, the speed corresponding to the fifth speed gear is greater than the speed corresponding to the fourth speed gear, and in the embodiment, the third temperature interval refers to the freezing chamber temperature being greater than the fifth preset temperature, i.e., Td>a5, and the compressor speed gear relationship is S1<S2<S3<S4<S5, S5 is the highest speed.

[0066] The compressor in the refrigerator 110 is controlled to run according to the second running gear to reduce the freezing chamber temperature to achieve the ultra-low temperature freezing effect of the deep-freezing refrigeration temperature as soon as possible.

[0067] In one embodiment, after the compressor in the refrigerator 110 is started, the method further includes:

[0068] In a case that at least one of the following conditions is met: the freezing chamber temperature is less than or equal to a preset shutdown temperature, the freezing chamber temperature is located in a first preset temperature range, a continuous running time of the compressor is greater than or equal to a first continuous time, and a running time of the compressor is greater than or equal to a second continuous time, the compressor is shut down, wherein the preset shutdown temperature is lower than the deep freezing temperature, the first preset temperature range is from the preset shutdown temperature to a preset candidate temperature, and the preset candidate temperature is greater than the preset shutdown temperature and less than the deep freezing temperature.

[0069] Specifically, the preset shutdown temperature is lower than the deep freezing temperature, for example, the preset shutdown temperature is a3-3, a3-4, a3-5, etc., and in the embodiment, the preset shutdown temperature is a3-3, and in a case that a3 is selected as -37℃, the preset shutdown temperature is -40℃. The preset candidate temperature is greater than the preset shutdown temperature, for example, in a case that the preset shutdown temperature is a3-3, the preset candidate temperature can be a3-2 or a3-1, and in the embodiment, the preset candidate temperature is a3-2, and thus the first preset temperature range is (a3-3, a3-2]. As shown in FIG. 3, in a case that at least one of the following conditions is met in the running state of the compressor: the freezing chamber temperature is less than or equal to the preset shutdown temperature (Td≤a3-3), the freezing chamber temperature is located in the first preset temperature range, the continuous running time of the compressor is greater than or equal to the first continuous time t5 (tc1≥t5), and the running time of the compressor is greater than or equal to the second continuous time t6 (tc2≥t6), the compressor is shut down, wherein the first continuous time t5 is in a range of 1≤t5≤3, and the preferred value is 2, and the second continuous time t6 is in a range of 11≤t6≤13, and the unit is h. Figure 5

[0070] The freezing chamber temperature being equal to or lower than the preset shutdown temperature or indicating that the freezing chamber temperature is low enough under the premise of being lower than the deep freezing temperature, and the compressor does not need to continue to provide the ultra-low temperature refrigeration capacity, and thus the compressor can be shut down to save the running energy consumption of the compressor. In a case that the continuous running time of the compressor is greater than or equal to the first continuous time in a case that the freezing chamber temperature is lower than the preset candidate temperature and higher than the preset shutdown temperature, the freezing chamber temperature is maintained in the temperature range for a time reaching or exceeding the first continuous time, indicating that the freezing chamber temperature is stabilized between the preset shutdown temperature and the preset candidate temperature by the continuous running of the compressor for a period of time, and the ultra-low temperature refrigeration effect is also met, and the compressor can also be shut down to save the running energy consumption of the compressor. In a case that the running time of the compressor is greater than or equal to the second continuous time, it means that the compressor has been running for a long time, and thus the compressor needs to be shut down for maintenance.

[0071] In an embodiment, after the control of the compressor to run in the second running gear, the method further includes:

[0072] ​In at least one of the following conditions: the working state of the compressor is stopped, the freezing chamber temperature is greater than a preset zeroing temperature, and the switch state of the defrosting heater is turned on, the continuous running time length and the start-up running time length of the compressor are zeroed, wherein the preset zeroing temperature is greater than a deep-freezing refrigeration temperature.

[0073] Specifically, for the zeroing condition of the continuous running time length and the start-up running time length of the compressor after the freezing chamber temperature is in the first preset temperature range, the zeroing condition includes: the compressor is stopped, the freezing chamber temperature rises to above the preset zeroing temperature, and the defrosting heater is turned on, wherein the preset zeroing temperature is higher than the deep-freezing refrigeration temperature, for example, the preset zeroing temperature is a3+1, a3+3, a3+5, a3+7, etc., and in the embodiment, the preset zeroing temperature is a3+7. When the freezing chamber temperature rises to above the preset zeroing temperature, i.e., Td>a3+7, the compressor needs to continue running to provide refrigeration capacity in order to reduce the freezing chamber temperature to the deep-freezing refrigeration temperature. However, in order to avoid triggering the compressor to stop when the start-up running time length reaches the second continuous time length, the start-up running time length is zeroed to ensure that the start-up running time length of the compressor does not cause the compressor to stop, and the compressor can continue to run normally to provide refrigeration capacity.

[0074] In one embodiment, the step of controlling the refrigerator 110 to run in the second refrigeration mode until the freezing chamber temperature is less than or equal to the deep-freezing refrigeration temperature, and the running parameter of the compressor in the refrigerator 110 meets the preset defrosting condition, and then controlling the refrigerator 110 to run in a preset defrosting mode until the running parameter of the refrigerator 110 meets the exit condition of the preset defrosting mode, and then controlling the refrigerator 110 to exit the preset defrosting mode and run in the second refrigeration mode, includes:

[0075] When the continuous running time length of the compressor is greater than or equal to a third continuous time length in the second preset temperature range of the freezing chamber temperature, the step of opening the defrosting heater in the refrigerator 110, zeroing the first timing time length and re-timing, and timing the opening time length of the defrosting heater to the compressor speed gear corresponding to the temperature interval of the freezing chamber temperature as the second running gear, and then controlling the compressor to run in the second running gear, wherein the second preset temperature range is a preset candidate temperature to the deep-freezing refrigeration temperature, and the preset candidate temperature is less than the deep-freezing refrigeration temperature.

[0076] Specifically, referring to Figure 6, the preset candidate temperature is a3-2 according to the foregoing embodiment, and thus the second preset temperature range is (a3-2, a3]. When the continuous running time tc3 of the compressor after the freezing chamber temperature is located in the second preset temperature range is greater than or equal to the third continuous time t7 (tc3≥t7), it indicates that the maintenance time of the freezing chamber temperature below the deep-freezing refrigeration temperature but above the preset candidate temperature is greater than or equal to the third continuous time. The maintenance time of the freezing chamber temperature located in the second preset temperature range is determined according to the continuous running time of the compressor, which reflects that the continuous work of the compressor in the maintenance time cannot reduce the freezing chamber temperature to the preset candidate temperature or the preset shutdown temperature, and indicates that the frost amount on the evaporator affects the refrigeration effect of the compressor, that is, the thickness of the frost on the evaporator is relatively thick, and thus the forced defrosting heater needs to be forced to be turned on to perform forced defrosting, so as to avoid the adverse effect of the frost on the ultra-low-temperature refrigeration effect, that is, the execution step of circulating to the preset defrosting mode to the second refrigeration mode.

[0077] The third continuous time t7 is 3≤t7≤5, and the preferred value is 4, in units of h. According to the foregoing embodiment, the third continuous time t7 is also cleared under the following conditions: the compressor is shut down, the freezing chamber temperature rises above the preset clearing temperature, and the defrosting heater is turned on.

[0078] In one embodiment, after the first timing duration is obtained, the method further includes:

[0079] When the first timing duration is greater than or equal to the first cumulative duration, the step of turning on the defrosting heater in the refrigerator 110, clearing the first timing duration, and timing the opening duration of the defrosting heater to the compressor speed gear corresponding to the temperature interval of the freezing chamber temperature as the second running gear, and controlling the compressor to run according to the second running gear is performed, wherein the first cumulative duration is greater than the first preset duration.

[0080] Specifically, the first cumulative duration is greater than the first preset duration, and the first cumulative duration is used to indicate the time interval of the timing defrosting. The first cumulative duration t8 is 48≤t8≤72, and the preferred value is 60, in units of h. According to the foregoing embodiment, the first cumulative duration t8 is also cleared under the following conditions: the compressor is shut down, the freezing chamber temperature rises above the preset clearing temperature, and the defrosting heater is turned on. Figure 7In a case where the first timing duration is greater than or equal to the first accumulated duration, i.e., tps≥t8, the refrigerator 110 is controlled to cycle to the steps corresponding to the preset defrosting mode and the second refrigeration mode, i.e., whether to start the compressor is determined according to the comparison result between the temperature of the freezing chamber and the deep-freezing refrigeration temperature, and in a case where the compressor is in the started state, the second operation gear of the compressor is determined according to the compressor speed gear corresponding to the temperature interval to which the temperature of the freezing chamber belongs, so as to control the compressor to work according to the corresponding second operation gear, and through the above cycle logic, long-time stable ultra-low-temperature refrigeration can be realized. In this stage, the zeroing condition of the first timing duration is prior to timing, i.e., once the defrosting cycle or the defrosting heater is started, the first timing duration is zeroed and re-timed, and the defrosting cycle includes the preset refrigeration phase corresponding to the first refrigeration mode and the defrosting phase corresponding to the preset defrosting mode.

[0081] In one embodiment, in a case where the deep-freezing function is started, the method further includes:

[0082] Timing the starting duration of the deep-freezing function to obtain a second timing duration;

[0083] In a case where the shutdown instruction of the deep-freezing function is received, and / or the second timing duration is greater than or equal to a second accumulated duration, the deep-freezing function is shut down, and the first timing duration and the second timing duration are zeroed, wherein the second accumulated duration is greater than the first accumulated duration;

[0084] Controlling the refrigerator 110 to work according to the preset refrigeration mode.

[0085] Specifically, referring to Figure 8, the second cumulative time length t2 is far greater than the first cumulative time length, the value range of the second cumulative time length is 360≤t2≤720, and the preferred value is 480, the unit is h. When receiving the shutdown instruction of the deep freezing function, and / or the second timing length is greater than or equal to the second cumulative time length, the deep freezing function is turned off and the first timing length and the second timing length are cleared. After the first timing length is cleared, the deep freezing function is restarted. The shutdown instruction of the deep freezing function can be triggered by the user manually turning off the deep freezing icon in the operation panel of the refrigerator 110, or by the user transmitting the deep freezing function start command to the refrigerator 110 through the terminal, or by the voice command or gesture command initiated by the user. After the refrigerator 110 turns off the deep freezing function, the running mode of the refrigerator 110 is restored to the preset refrigeration mode before the deep freezing function is started, so as to restore the ultra-low temperature freezing effect to the normal freezing effect. Wherein, the second timing length tcd starts to count as soon as the deep freezing function is started. During the counting process of the second timing length, the power-off record of the second timing length will be recorded when the refrigerator 110 is powered off, that is, the value of the second timing length at the time of power-off is recorded to obtain the power-off time length. After the refrigerator 110 is powered on again, the second timing length will continue to count on the basis of the power-off time length.

[0086] In one specific embodiment, with reference to Figures 2 to 8 :

[0087] 1. The user manually lights up the deep freezing icon in the operation panel of the refrigerator 110, the ultra-freezing function is started, and the second timing length tcd is started to count;

[0088] 2. The refrigerator 110 keeps the original preset refrigeration mode running at this time, and reads the first timing length tps at this time;

[0089] 3. Determine whether tps≥t1 (t1 value range is 5≤t1≤7, preferred value is 6, unit is h) is established, if established, run according to the first refrigeration mode, if not established, continue to run according to the original preset refrigeration mode, and collect the first timing length tps at any time;

[0090] 4. Run according to the first refrigeration mode:

[0093] (3) Collect the freezing chamber set temperature, i.e. the pre-cooling temperature Tsd (herein the pre-cooling temperature is -18℃), the freezing evaporator sensor temperature Tzf;

[0094] (4) Determine whether Tsd-Tzf≤a2 (a2 takes the value range of 2≤a2≤4, and the preferred value is 3, unit: ℃) is established, if yes, then determine the compressor running time in this stage as t3 (t3 takes the value range of 55≤t3≤65, and the preferred value is 60, unit: min); if not, then determine the compressor running time in this stage as t4 (t4 takes the value range of 25≤t4≤35, and the preferred value is 30, unit: min);

[0095] (5) After the compressor runs according to the determined speed gear and running time, enter the defrosting stage corresponding to the preset defrosting mode;

[0096] 5. Run according to the preset defrosting mode:

[0097] Turn on the defrosting heater, when the opening time of the defrosting heater reaches the set value or the freezing evaporator temperature reaches the exit temperature, exit this defrosting cycle and enter the super-low-temperature refrigeration cycle corresponding to the second refrigeration mode;

[0098] 6. Enter the super-low-temperature refrigeration cycle corresponding to the second refrigeration mode:

[0099] (1) Collect the freezing chamber temperature Td and the deep-freezing refrigeration temperature a3 (a3 takes the value range of -36≤a3≤-38, and the preferred value is -37, unit: ℃);

[0100] (2) In the compressor shutdown state, determine whether it is in the refrigeration stage and whether Td>a3 is established, if yes, then turn on the compressor for deep-freezing refrigeration, if not, then control the compressor not to start;

[0101] (3) The speed control determination condition of the compressor in the start state: if a3

[0102] (4) Compressor in the start state stop decision condition: determine whether Td≤a3-3, Td≤a3-2 after the compressor continuous running time tc1≥t5 (t5 value range is 1≤t5≤3, the preferred value is 2, unit: h), the compressor continuous working time tc2≥t6 (t6 value range is 11≤t6≤13, the preferred value is 12, unit: h) any one of the following conditions is established, if the above three any one condition is met, the compressor is stopped (the compressor continuous working time tc1, tc2 zero condition in this stage has three, any one condition is met, zero: compressor stop; freezer temperature rises to meet Td>a3+7; defrost heater is turned on);

[0103] (5) determine whether Td≤a3 after the compressor continuous running time tc3≥t7 (t7 value range is 3≤t7≤5, the preferred value is 4, unit: h) and Td>a3-2 is established (the compressor continuous working time tc3 zero condition in this stage has three, any one condition is met, zero: compressor stop; freezer temperature rises to meet Td>a3+7; defrost heater is turned on);

[0104] (6) if not established, continue to run according to the current refrigeration rule, if established, enter the second refrigeration mode corresponding to the forced defrost stage;

[0105] (7) enter the forced defrost stage, at this time the first timing duration tps is zero and restarts timing, return to step 5 above;

[0106] 7. Timed defrosting control as follows:

[0107] (1) after entering the super freezing process (the second refrigeration mode corresponding to the ultra-low temperature refrigeration stage), the program always times the first timing duration tps (in this stage, the tps zero condition is prior to timing, that is, after meeting the first timing duration zero condition, tps timing is zero and restarts timing);

[0108] (2) determine whether tps≥t8 (t8 value range is 48≤t8≤72, the preferred value is 60, unit: h) is established;

[0109] (3) if not established, continue to run according to the current refrigeration rule, if established, enter the preset defrosting mode corresponding to the defrosting stage, that is, return to execute step 5 above;

[0110] 8. After the deep freeze icon is lit, the program starts timing the super freezing time, that is, the second timing duration tcd, and the display state of the deep freeze icon is collected at all times, that is, whether the deep freeze icon is extinguished is determined;

[0111] (1) determine whether tcd≥t2 (t2 value range is 360≤t2≤720, the preferred value is 480, unit: h) or the deep freeze icon is detected to be touched and extinguished is established;

[0112] (2) If true, exit the super-freeze function and clear the second timing duration tcd to zero, and stop timing; clear the first timing duration tps to zero and start timing again;

[0113] (3) After exiting the deep freeze function, control the refrigerator 110 to operate in the normal preset cooling mode.

[0114] Based on the above refrigerator control method, the superfreeze function is divided into two control stages after activation. The first stage includes a pre-cooling stage corresponding to the first cooling mode and a normal defrosting stage corresponding to the preset defrosting mode. The second stage includes a forced cooling stage (second cooling mode), a forced defrosting stage, and a timed defrosting stage. First, based on the time interval since the last defrost, it is determined whether the normal defrosting in the first stage of the superfreeze function (deep freeze function) should be executed. This stage effectively avoids large temperature fluctuations in the compartment caused by repeated defrosting. By comprehensively controlling the compressor's operating parameters based on the current ambient temperature, the evaporator temperature, and the pre-cooling temperature, it effectively prevents a large temperature rise in the compartment after defrosting. Simultaneously, the defrosting heating in this stage, which removes frost from the evaporator, facilitates longer cooling in the next stage. After the first stage is completed, the second stage of the superfreeze process begins. This process is divided into a forced cooling stage, a forced defrosting stage, and a timed defrosting stage. This process optimizes the compressor's operating parameters and defrosting control logic, ensuring the freezer compartment remains stably in an ultra-low temperature environment for a long period, while the reliability of defrosting is not affected by prolonged cooling. It can achieve long-term ultra-low temperature preservation in the freezer compartment, improve the food preservation environment, reduce the loss of food freshness, and ensure the temperature uniformity and stability of the refrigerator under the super-freezing function. It can also ensure that the evaporator frost layer will not accumulate too thickly under long-term cooling, thus saving energy.
