It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.

s11: acquiring a real-time temperature in the freezer compartment after the instant freezing procedure is performed;
s12: the real-time temperature at the current moment is differed from the real-time temperature before the preset duration to obtain a temperature difference value at the current moment;

After the instant freezing program is executed, whether the freezing chamber is influenced by external environmental factors can be judged according to the temperature difference; thus, when the influence is not caused, the instant freezing program can be continuously executed; ensuring the smooth execution of the instant freezing program; when the instant freezing program is influenced, the instant freezing program can be stopped to be executed, further control is carried out, the problems that large-area freezing of food occurs, the low-temperature non-freezing equilibrium state below a freezing point is damaged, and the food fresh-keeping effect is poor are avoided, and therefore the food fresh-keeping effect can be guaranteed no matter whether the instant freezing program is influenced by external factors or not when the instant freezing program is executed in the scheme of the application
Second embodiment, as a supplementary description to the first embodiment, the present invention provides a specific instant freezing control method for a freezer compartment of a refrigerator, comprising the steps of:
acquiring a real-time temperature in the freezer compartment after the instant freezing procedure is performed; the instantaneous freezing program comprises four stages of supercooling environment preparation, supercooling introduction, supercooling maintenance and-5 ℃ maintenance operation;
the real-time temperature at the current moment is differed from the real-time temperature before the preset duration to obtain a temperature difference value at the current moment; the preset duration is determined according to actual conditions.
Controlling whether to continue to execute the instant freezing program according to the temperature difference; specifically, when the temperature difference is greater than 0, the stage where the current time is located is determined, and after the temperature difference is affected by the outside, the temperature in the freezing chamber rises, that is, the temperature difference is greater than 0, so that the next judgment is performed when the temperature difference is greater than 0.
In the supercooled state (supercooled introduction and supercooled maintenance phase) of the instant freezing technique, the food is kept in a low-temperature state always below the freezing point, and is kept in an unfrozen equilibrium state, and the food is not damaged by the ice crystals in this state; if the food is affected by external disturbance factors such as low-temperature air blown out from the air duct in this state, the supercooled state may be destroyed, and the food may be frozen in a large area, and the low-temperature non-freezing equilibrium state below the freezing point may be destroyed. Therefore, although the instant freezing process includes four stages, it is necessary to judge the stage in the first stage since the supercooling environment is prepared and the fourth stage is maintained at-5 ℃ without causing the food to be damaged by the ice crystals.
In actual control, two ways can be generally adopted for judging the stage, one way is to compare the real-time temperature at the current moment with the preset temperature range of each stage to determine the stage at the current moment. The four stages of the instant freezing program have standard temperature curves as shown in fig. 1, and the temperature of each stage is different, so that the stage can be judged according to the temperature. Another method can obtain the control time length of the refrigerator for executing the instant freezing program, and compare the control time length with the preset unfreezing time length to determine the stage of the current time. In the actual control process, the control duration of each stage is required, so that the stage at which the current time is located can be determined according to the control duration after the instantaneous freezing program is started.
And when the current moment is in the supercooling leading-in or supercooling maintaining stage, controlling whether to continuously execute the instant freezing program or not according to the size relation between the temperature difference and a first preset value and a second preset value, wherein the first preset value is smaller than the second preset value. That is, only when the second stage supercooling lead-in or the third stage supercooling maintenance is performed, the external factors influence the freezing by mistake, and the fresh-keeping effect is influenced. In the actual control process, when the temperature is found to be greater than 0, there are three cases, i.e., normal temperature fluctuation, temperature rise when the supercooled state is broken, and new food is put into the freezer compartment. The temperature rise values in the three cases are different, wherein when the normal temperature fluctuates, the rise value, i.e. the temperature difference value is minimum, and generally does not exceed the first preset value, while when the overcooled state is damaged, the temperature difference value is higher under the condition that the temperature rises again, and generally is between the first preset value and the second preset value, and when new food is put in, the temperature difference value is highest and generally is larger than the second preset value. Therefore, which kind of situation is judged according to the temperature difference value, the first preset value and the second preset value so as to carry out accurate control and ensure the food preservation effect. It can be understood that the first preset value and the second preset value may have a certain variation according to the storage condition of the freezing chamber, and thus the first preset value and the second preset value are set according to the actual condition.
And when the temperature difference value is greater than the first preset value and less than the second preset value, stopping executing the instant freezing program, and simultaneously controlling the freezing chamber to unfreeze and re-executing the instant freezing program after unfreezing. The method comprises the steps of controlling the freezing chamber to unfreeze and re-executing the instant freezing program after unfreezing, wherein the steps of controlling the temperature in the freezing chamber to rise to a preset temperature and maintaining the preset unfreezing time and then re-executing the instant freezing program are included. When the temperature difference is between the first preset value and the second preset value, the situation that the temperature rises back when the overcooling state is damaged is judged, at the moment, the food is frozen, therefore, the food needs to be unfrozen, and the instant freezing program is executed again after the unfreezing.
And when the temperature difference is not greater than the first preset value, continuing to execute the instant freezing program. When the temperature difference is not greater than the first preset value, the conventional temperature fluctuation is only indicated, the food preservation effect cannot be influenced, and the instant freezing program is continuously executed at the moment.
And when the temperature difference is not less than the second preset value, directly re-executing the instant freezing program. When the temperature difference is not less than the second preset value, the new food is put into the freezing chamber, at the moment, the new food needs to be instantly frozen, the original food is not frozen, the unfreezing is not needed, and the instant freezing program is directly executed again.
Specifically, as shown in fig. 3, the refrigerator enters an instant freezing process after being operated, the first stage is a supercooling environment preparation stage, in general, food is cooled or heated up according to 2 ℃ control, the second stage is supercooling introduction, the temperature is controlled to gradually decrease for cooling, the third stage is a supercooling maintaining state, and the fourth stage is a-5 ℃ maintaining operation; a first preset value T1 and a second preset value T2, wherein T1 is less than T2; when in the first stage, if food is put into the food processing device, the temperature reduction process of the food in the program is not influenced, so that the food processing device can continuously operate according to the program; when food is put into the food fresh-keeping device in the second and third stages, the hot food can damage the food which is already in the overcooling state, and the food fresh-keeping effect is influenced; if the balance state is damaged by external influence, the food is frozen into ice blocks in a large area, and the preservation effect after the program operation is greatly damaged; therefore, the sensor monitors the temperature in real time in the supercooling state, the real-time temperature in the freezing chamber is collected, the temperature difference value T3 at the current moment is obtained, if T1 is more than T3 and less than T2, the supercooling is judged to be damaged by the external influence to be in a balanced state, the instant freezing program does not continue to run and unfreeze, and the program is executed again when the unfreezing time reaches the preset unfreezing time T; if T2 is less than T3, the situation that the food fresh-keeping effect cannot reach the expected effect due to the damage of the instant freezing and supercooling state can be avoided.
The control method provided by the embodiment of the invention judges through the detection failure of the temperature sensor or the temperature rise of the food input, and the program restarts to execute after the judgment to ensure the fresh-keeping effect of the refrigerator. The control method ensures the complete stage of the supercooling state in the instant freezing and improves the fresh-keeping function of the product.

Wherein, determining the current time phase comprises: and comparing the real-time temperature at the current moment with the preset temperature range of each stage to determine the stage at the current moment.
