Fig. 1 is an application environment diagram of a refrigerator control method in one embodiment. 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 may be integrally provided, or may be separately provided, and in this embodiment, the refrigerator 110 and the refrigerator control device 120 are integrally provided.

In one embodiment, fig. 2 is a schematic flow chart of a control method of a refrigerator according to one embodiment, and referring to fig. 2, a control method of a refrigerator is provided. The present embodiment is mainly exemplified by the application of the method to the terminal control device 120 in fig. 1, and the refrigerator control method specifically includes the following steps:

In step S210, when the deep freezing function is turned on, the refrigerator 110 is controlled to operate in a first cooling mode, wherein parameters adjusted in the first cooling mode include a pre-cooling temperature for reducing the temperature of the freezing chamber of the refrigerator 110 and a first cooling duration.

Specifically, when the deep freezing function is turned off, the refrigerator 110 operates according to a preset refrigeration mode, wherein the refrigeration temperature of the preset refrigeration mode is higher than the refrigeration temperature corresponding to the deep freezing function, and the preset refrigeration mode may specifically be a default refrigeration mode of the refrigerator 110 or a user-defined refrigeration mode. The opening of the deep freezing function may be specifically triggered by a user manually operating the operation panel of the refrigerator 110, for example, the user lights a deep freezing icon in the operation panel of the refrigerator 110, or the user remotely transmits the deep freezing function to the refrigerator 110 through a terminal to open the refrigeration, or the user initiates a voice command or a gesture command. When the deep freezing function is started, the refrigerator 110 is pre-cooled according to the first cooling mode, and the temperature of the freezing chamber of the refrigerator 110 is reduced according to the pre-cooling temperature.

Step S220, when the operation of the refrigerator 110 is finished according to the first cooling duration, controlling the refrigerator 110 to operate according to a preset defrosting mode, and collecting the operation parameters of the refrigerator 110 in real time.

Specifically, after the operation of the refrigerator 110 according to the first refrigerating duration is finished, the refrigerator 110 is operated according to a preset defrosting mode, namely, the refrigerator 110 is enabled to defrost the freezing chamber, and the pre-refrigeration treatment is carried out on the freezing chamber before defrosting, so that the temperature difference before and after defrosting can be ensured not to be too large, namely, the temperature rise between the freezing chambers after defrosting is effectively prevented from being too large, the influence of defrosting on the temperature fluctuation of the freezing chamber can be reduced, the uniformity and the stability of the temperature of the freezing chamber are ensured, and the defrosting in the stage is beneficial to the long-time ultralow-temperature refrigeration in the next stage.

And step S230, when the operation parameters of the refrigerator 110 meet the exit conditions of the preset defrosting mode, controlling the refrigerator 110 to exit the preset defrosting mode and operate according to a second refrigeration mode, wherein the parameters adjusted by the second refrigeration mode include a deep freezing temperature for reducing the temperature of the freezing chamber, and the deep freezing temperature is lower than the pre-cooling temperature.

Specifically, the operation parameters of the refrigerator 110 include the operation parameters of each device in the refrigerator 110, the devices in the refrigerator 110 specifically include an evaporator in a freezing chamber, a temperature sensor on the evaporator, a temperature sensor in the freezing chamber, a compressor, a defrosting heater, and the like, when the operation parameters of the refrigerator 110 meet the exit conditions of the preset defrosting mode, the refrigerator 110 is controlled to exit the preset defrosting mode and operate according to the second refrigeration mode, that is, the refrigerator 110 is controlled to reduce the temperature of the freezing chamber according to the deep freezing temperature to realize ultralow temperature preservation, the deep freezing temperature is lower than the preset freezing temperature, and the refrigerator 110 is subjected to the pre-freezing and defrosting treatment before deep freezing, so that the frost formation amount at the stage is reduced, the ultralow freezing effect at the stage can be ensured, that is, the influence of the frost formation amount on the deep freezing effect at the stage is reduced.

Step S240, when the refrigerator 110 is operated in the second cooling mode until the temperature of the freezing chamber is less than or equal to the deep freezing temperature, and the operation parameter of the compressor in the refrigerator 110 meets the preset defrosting condition, executing the steps of controlling the refrigerator 110 to operate in the preset defrosting mode until the operation parameter of the refrigerator 110 meets the exit condition of the preset defrosting mode, controlling the refrigerator 110 to exit the preset defrosting mode, and operating in the second cooling mode.

Specifically, when the refrigerator 110 is operated to the freezing chamber temperature less than or equal to the deep freezing temperature according to the second refrigeration mode, and the operation parameters of the compressor meet the preset defrosting conditions, the refrigerator 110 is controlled to perform defrosting treatment according to the preset defrosting mode again, when the freezing chamber temperature of the refrigerator 110 reaches or even is lower than the deep freezing temperature, the frost forming condition in the freezing chamber is judged based on the operation parameters of the compressor, and defrosting treatment is performed again when the frost forming condition meets the preset defrosting conditions.

In one embodiment, when the deep freezing function is turned on, the refrigerator 110 is controlled to operate in the first cooling mode, which includes:

when the deep freezing function is started, acquiring the current ambient temperature and the freezing evaporator temperature;

taking a compressor rotating speed gear corresponding to a comparison result between the current environment temperature and a first preset temperature as a first running gear, wherein the first refrigerating mode further comprises the first running gear;

taking the operation time length of the compressor corresponding to the comparison result between the temperature difference between the pre-cooling temperature and the freezing evaporator temperature and the second preset temperature as a first refrigeration time length;

and controlling the compressor in the refrigerator 110 to operate according to the first operation gear and the first refrigerating time period.

Specifically, as shown in fig. 3, when the deep freezing function is started, the current ambient temperature Th and the freezing evaporator temperature Tzf are obtained, the freezing evaporator temperature is the temperature acquired by a temperature sensor on the evaporator, the current ambient temperature is compared with a 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, the first preset temperature can be set in a self-defined manner according to different application scenarios, and in the embodiment, the value range of the first preset temperature is 28 ℃ to be less than or equal to a1 to be less than or equal to 32 ℃, and the preferred value is 30 ℃. The step of taking the rotational speed gear of the compressor corresponding to the comparison result between the current ambient temperature and the first preset temperature as the first running gear specifically comprises the following steps: when the current ambient temperature is greater than or equal to a first preset temperature, namely Th is greater than or equal to a1, taking the second rotating speed gear S2 as a first running gear; when the current ambient temperature is smaller than the first preset temperature, namely Th < a1, the first rotating speed gear S1 is used as the first running gear, and the rotating speed corresponding to the second rotating speed gear is larger than the rotating speed corresponding to the first rotating speed gear. That is, when the current ambient temperature is equal to or higher than the first preset temperature, the refrigerator 110 needs more refrigeration capacity, and thus the refrigerator 110 needs to operate at a high rotational speed to provide more refrigeration capacity; when the current ambient temperature is lower than the first preset temperature, the refrigerator 110 requires less cooling capacity, and thus the refrigerator 110 operates at a low rotational speed to provide lower cooling capacity.

And taking the operation time length of the compressor corresponding to the comparison result between the temperature difference between the pre-cooling temperature and the freezing evaporator temperature and the second preset temperature as a first refrigeration time length, wherein the operation time length specifically comprises the following steps: the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is compared with a second preset temperature, namely, whether the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is larger than the second preset temperature is judged, the pre-cooling temperature is recorded as Tsd, the second preset temperature is recorded as a2, the pre-cooling temperature and the second preset temperature can be subjected to self-defining setting according to different application scenes, in the embodiment, the pre-cooling temperature is enabled to be-18 ℃, the value range of the second preset temperature is 2 ℃ to be less than or equal to 4 ℃, and the preferred value is 3 ℃. Judging whether the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is larger than a second preset temperature, namely judging whether Tzf is smaller than or equal to Tsd-a2 or not, and judging Tzf on the basis that Tsd is minus 18 ℃ and a2 is 3 DEG C ^≥ Whether or not the temperature of 21 ℃ below zero is established.

When the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is less than or equal to a second preset temperature, i.e. Tsd-Tzf is less than or equal to a2, such as Tzf ^≥ -21 ℃, representing the freezing evaporator temperature and prefabrication The cold temperature is relatively close, in order to enable the temperature of the freezing evaporator to be further lower than the pre-made cold temperature so that the temperature after subsequent defrosting can still be kept near the pre-made cold temperature, the temperature of a freezing compartment before and after defrosting is ensured not to have larger temperature fluctuation, the compressor is required to provide more refrigerating capacity, and then the first time length threshold t3 is used as the first refrigerating duration; when the temperature difference between the pre-cooling temperature and the freezing evaporator temperature is greater than a second preset temperature, i.e. Tsd-Tzf>a2, e.g. Tzf<21 ℃ below zero, which means that the temperature of the freezing evaporator is lower than the pre-cooling temperature to a larger extent, and the second time period threshold t4 is used as the first refrigerating time period without the need of providing more refrigerating capacity by the compressor, wherein the first time period threshold is larger than the second time period threshold, the value range of the first time period threshold t3 is 55-t 3-t 65, the preferred value is 60, the value range of the second time period threshold t4 is 25-t 4-t 35, the preferred value is 30, and the unit is min.

The compressor in the refrigerator 110 is controlled to pre-refrigerate according to the first operating gear and the first refrigerating time period, and the temperature of the freezing chamber of the refrigerator 110 is reduced to be lower than the pre-cooling temperature and is different from the pre-cooling temperature by a certain temperature before defrosting.

In one embodiment, before the obtaining the current ambient temperature and the freezing evaporator temperature, the method further comprises:

acquiring a first timing duration, wherein the first timing duration is used for indicating a time interval from the current moment to the last time the refrigerator 110 is controlled to execute a preset defrosting mode;

and executing the step of acquiring the current environment temperature and the freezing evaporator temperature when the first timing time is longer than or equal to a first preset time.

Specifically, when the deep freezing function is started, the refrigerator 110 still keeps the current operation mode to continue to operate, and obtains a first timing duration tps, where the first timing duration tps is used to indicate a time interval from the last operation of the preset defrosting mode, and when the first timing duration is greater than or equal to a first preset duration t1, the steps of obtaining the current ambient temperature and the temperature of the freezing evaporator and thereafter are performed, the first preset duration is used to indicate a preset time interval for allowing defrosting, and the subsequent first refrigeration mode and the preset defrosting mode are performed only when the previous defrosting is long enough, so that a large temperature fluctuation of the temperature between the freezing rooms caused by excessively high defrosting frequency can be effectively avoided, and in this embodiment, the value range of the first preset duration is 5.ltoreq.t1 and is preferably 6, where the unit is h. And when the first timing duration is smaller than the first preset duration, the subsequent first refrigeration mode and the preset defrosting mode are not executed, and refrigeration is continued according to the current operation mode, so that the temperature of the refrigerating compartment is prevented from repeatedly rising, and the step of acquiring the first timing duration is circularly executed.

In one embodiment, the controlling the refrigerator 110 to operate in a preset defrosting mode includes:

starting a defrosting heater in the refrigerator 110, resetting the first timing duration, and timing the starting duration of the defrosting heater;

when the operation parameters of the refrigerator 110 meet the exit conditions of the preset defrosting mode, controlling the refrigerator 110 to exit the preset defrosting mode and operate according to a second refrigeration mode, including:

when the on-time of the defrosting heater reaches a preset heating time and/or the temperature of the freezing evaporator in the refrigerator 110 reaches a preset exit temperature, turning off the defrosting heater and judging whether the temperature of the freezing chamber is greater than the deep freezing temperature, wherein the operation parameters comprise the on-time of the defrosting heater and the temperature of the freezing evaporator;

when the freezing chamber temperature is greater than the deep freezing temperature, turning on a compressor in the refrigerator 110;

taking a rotational speed gear of the compressor corresponding to a temperature interval to which the temperature of the freezing chamber belongs as a second operation gear, and controlling the compressor to operate according to the second operation gear, wherein the second refrigeration mode further comprises the second operation gear for controlling the operation of the compressor.

Specifically, when the refrigerator 110 operates according to the preset defrosting mode, the defrosting heater in the refrigerator 110 is turned on to defrost and heat the evaporator, the first timing duration is cleared to be re-timed when the refrigerator enters the preset defrosting mode, and the opening duration of the defrosting heat collector is timed.

When the on time of the defrosting heater reaches the preset heating time and/or the temperature of the freezing evaporator reaches the preset exit temperature, indicating that defrosting is finished, the defrosting heater is turned off, whether the temperature of the freezing chamber is larger than the deep freezing temperature or not is judged, the temperature of the freezing chamber is marked as Td, the deep freezing temperature is marked as a3, the value range of the deep freezing temperature in the embodiment is minus 36 ℃ to minus a3 to minus 38 ℃, and the preferable value is minus 37 ℃. If the temperature of the freezing chamber is lower than or equal to the deep freezing temperature, namely Td is less than or equal to a3, the temperature of the freezing chamber is still kept at or lower than the deep freezing temperature after defrosting, and the compressor is not required to operate for refrigeration, so that the working state of the compressor is stopped.

As shown in fig. 4, if the temperature of the freezing chamber is higher than the deep freezing temperature and is in the refrigerating stage, i.e., td > a3, which means that the temperature of the freezing chamber returns to above the deep freezing temperature after defrosting, in order to continue the ultralow temperature preservation of the deep freezing function, the compressor needs to be started to continue providing the refrigerating capacity to make the temperature of the freezing chamber reach or lower than the deep freezing temperature. Taking a rotational speed gear of the compressor corresponding to a temperature interval to which the temperature of the freezing chamber belongs as a second operation gear, specifically comprising: if the temperature of the freezing chamber is in the first temperature interval, which means that the temperature difference between the temperature of the freezing chamber and the deep freezing temperature is smaller, and the ultra-low temperature refrigerating capacity required for reducing the temperature of the freezing chamber to the deep freezing temperature is smaller, the third rotation speed gear S3 is used as the second operation gear, the rotation speed corresponding to the third rotation speed gear is larger than the rotation speed corresponding to the second rotation speed gear, in this embodiment, the first temperature interval is (a 3, a 4), a4 is a fourth preset temperature, the value range of the fourth preset temperature is-33 ℃ to be-a4 to be-31 ℃, and the preferred value is-32 ℃.

If the temperature of the freezing chamber is in the second temperature interval, which means that the temperature difference between the temperature of the freezing chamber and the deep freezing temperature is larger, and the ultra-low temperature refrigerating capacity required for reducing the temperature of the freezing chamber to the deep freezing temperature is more, the fourth rotation speed gear S4 is used as the second operation gear, and the rotation speed corresponding to the fourth rotation speed gear is greater than the rotation speed corresponding to the third rotation speed gear, in this embodiment, the second temperature interval is (a 4, a 5), a5 is the fifth preset temperature, the value range of the fifth preset temperature is-28 ℃ to be-a4 to be-26 ℃, and the preferred value is-27 ℃.

If the temperature of the freezing chamber is in the third temperature interval, which means that the temperature difference between the temperature of the freezing chamber and the deep freezing temperature is large, in order to quickly reduce the temperature of the freezing chamber to the deep freezing temperature, the fifth rotational speed gear S5 is used as the second operation gear, the rotational speed corresponding to the fifth rotational speed gear is greater than the rotational speed corresponding to the fourth rotational speed gear, in this embodiment, the third temperature interval means that the temperature of the freezing chamber is greater than the fifth preset temperature, namely Td > a5, and the rotational speed gear relationship of the compressor comprises: s1 is more than S2 and less than S3 and less than S4 and less than S5, and S5 is the highest rotating speed.

The compressor in the refrigerator 110 is controlled to operate in the second operating range to lower the temperature of the freezing chamber to achieve an ultra-low temperature freezing effect of deep freezing temperatures as soon as possible.

In one embodiment, after the turning on of the compressor in the refrigerator 110, the method further comprises:

and closing the compressor when at least one of the continuous operation time length of the compressor is greater than or equal to a first continuous time length and the start-up operation time length of the compressor is greater than or equal to a second continuous time length within a first preset temperature range, 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.

Specifically, the preset shutdown temperature is lower than the deep freezing temperature, for example, the preset shutdown temperatures are a3-3, a3-4, a3-5, etc., in this embodiment, the preset shutdown temperature is a3-3, and the preset shutdown temperature is-40 ℃ when a3 is selected to be-37 ℃. The preset candidate temperature is greater than the preset shutdown temperature, for example, when the preset shutdown temperature is a3-3, the preset candidate temperature may be a3-2 or a3-1, in this embodiment, the preset candidate temperature is made to be a3-2, so the first preset temperature range is (a 3-3, a3-2]. As shown in fig. 5, when the temperature of the freezing chamber is detected to be less than or equal to the preset shutdown temperature (Td less than or equal to a 3-3) in the starting state of the compressor, the continuous operation time tc1 of the compressor is greater than or equal to the first continuous time t5 (tc 1 less than or equal to t 5) after the temperature of the freezing chamber is located in the first preset temperature range, and the starting operation time tc2 of the compressor is greater than or equal to at least one of the second continuous time t6 (tc 2 less than or equal to t 6), the first continuous time is turned off, wherein the value range of the first continuous time is 1 less than or equal to t5 less than or equal to 3, the preferred value is 2, and the value range of the second continuous time is 11 less than or equal to t6 less than or equal to 13, and the unit is h.

The temperature of the freezing chamber is equal to or lower than the preset shutdown temperature or the freezing chamber is sufficiently low on the premise that the temperature of the freezing chamber is lower than the deep freezing temperature, and the compressor is not required to continuously provide ultralow-temperature refrigerating capacity, so that the compressor can be turned off to save the running energy consumption of the compressor. And when the temperature of the freezing chamber is lower than the preset candidate temperature but higher than the preset stop temperature, the continuous operation time of the compressor is longer than or equal to the first continuous time, and the maintenance time of the temperature of the freezing chamber in the temperature range reaches or exceeds the first continuous time, which means that the compressor continuously operates for a period of time to stabilize the temperature of the freezing chamber between the preset stop temperature and the preset candidate temperature, and also satisfies the ultralow temperature refrigeration effect, and the compressor can be turned off to save the operation energy consumption of the compressor. The length of time is greater than or equal to the second continuous length of time when the compressor is started, meaning that the compressor has been running for a longer period of time, and then requires shutdown maintenance.

In one embodiment, after said controlling said compressor to operate in said second operating range, said method further comprises:

when the working state of the compressor is in a stop state, the temperature of the freezing chamber is higher than a preset zero clearing temperature, and the on-off state of the defrosting heater is in an on state, the continuous operation duration and the starting operation duration of the compressor are cleared, wherein the preset zero clearing temperature is higher than the deep freezing refrigeration temperature.

Specifically, the zero clearing conditions for the continuous operation duration of the compressor and the start-up operation duration of the compressor after the temperature of the freezing chamber is in the first preset temperature range include: the compressor is shut down, the temperature of the freezing chamber is raised back to above the preset zero clearing temperature, and the defrosting heater is turned on, wherein the preset zero clearing temperature is higher than the deep freezing temperature, for example, the preset zero clearing temperature is a3+1, a3+3, a3+5, a3+7, and the like, the preset zero clearing temperature is a3+7 in the embodiment, the compressor is required to continue to operate to provide refrigerating capacity in order to reduce the temperature of the freezing chamber to the deep freezing temperature when Td > a3+7 is raised back to the preset zero clearing temperature, but the compressor is prevented from being triggered to stop when the starting operation time of the compressor reaches the second continuous time, the starting operation time of the compressor is cleared to ensure that the starting operation time of the compressor does not lead to the compressor to stop, and the compressor is ensured to continue normal operation to provide the refrigerating capacity.

In one embodiment, when the refrigerator 110 is operated in the second cooling mode to the freezing chamber temperature is less than or equal to the deep freezing temperature, and the operation parameter of the compressor in the refrigerator 110 meets the preset defrosting condition, the step of controlling the refrigerator 110 to operate in the preset defrosting mode to control the refrigerator 110 to exit from the preset defrosting mode and operate in the second cooling mode is performed, where the operation parameter of the refrigerator 110 meets the exit condition of the preset defrosting mode, and the step includes:

And when the continuous operation duration of the compressor is greater than or equal to a third continuous duration within a second preset temperature range, executing the starting of the defrosting heater in the refrigerator 110, resetting the first timing duration, timing the starting duration of the defrosting heater to a step of taking a rotational speed gear of the compressor corresponding to a temperature interval to which the freezing chamber temperature belongs as a second operation gear, and controlling the compressor to operate according to the second operation gear, wherein the second preset temperature range is from a preset candidate temperature to the deep freezing temperature, and the preset candidate temperature is smaller than the deep freezing temperature.

The operation mode of the refrigerator 110 is restored to a preset cooling mode before the deep freezing function is opened after the deep freezing function of the refrigerator 110 is closed, so that the ultra-low temperature freezing effect is restored to the normal freezing effect. The second timing duration tcd starts to time as long as the deep freezing function is started, the refrigerator 110 is powered off halfway in the timing process of the second timing duration to record power off of the second timing duration, namely, the value of the second timing duration is recorded to obtain the power off duration when the power is off, and the refrigerator 110 is powered on again to continue to time the second timing duration on the basis of the power off duration.
