Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail with reference to the accompanying drawings and examples. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, based on the examples herein, which are within the scope of the application as defined by the claims, will be within the scope of the application as defined by the claims.
First embodiment referring to fig. 2, an embodiment of the present application provides a method for controlling instantaneous freezing of a freezing chamber of a refrigerator, comprising the steps of:
s11: after the instantaneous freezing program is executed, acquiring the real-time temperature in the freezing chamber;
s12: the real-time temperature at the current moment is differenced with the real-time temperature before the preset time length to obtain a temperature difference value at the current moment;
s13: whether the instant freezing program is continuously executed is controlled according to the temperature difference value.
According to the instantaneous freezing control method for the refrigerator freezing chamber, after an instantaneous freezing program is executed, the real-time temperature in the freezing chamber is obtained, and then the real-time temperature at the current moment is differentiated from the real-time temperature before the preset time length to obtain the temperature difference value at the current moment; and finally, controlling whether to continue to execute the instant freezing program according to the temperature difference value. After the instantaneous freezing program is executed, whether the freezing chamber is influenced by external environmental factors can be judged according to the temperature difference value; thus, when not affected, 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, and further control is performed to avoid the problem that the food is frozen in a large area, the low-temperature non-freezing equilibrium state below the freezing point is damaged, and the food fresh-keeping effect is poor, so that the instant freezing program is influenced by external factors or not when being executed, and the food fresh-keeping effect can be ensured
The second embodiment, as a supplementary explanation of the first embodiment, provides a specific method for controlling instantaneous freezing of a freezing chamber of a refrigerator, comprising the following steps:
after the instantaneous freezing program is executed, acquiring the real-time temperature in the freezing chamber; wherein, the instant 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 differenced with the real-time temperature before the preset time length to obtain a temperature difference value at the current moment; the preset time length is determined according to actual conditions.
Whether the instant freezing program is continuously executed or not is controlled according to the temperature difference value; specifically, when the temperature difference is greater than 0, the stage at the current moment is determined, and when the temperature difference is affected by the outside, the temperature in the refrigerating chamber is raised, that is, the temperature difference is greater than 0, so that the next judgment is performed only when the temperature difference is greater than 0.
In the supercooled state (supercooling introduction and supercooling maintaining phase) of the instant freezing technique, the food is preserved in a low temperature state which is not more than the freezing point, and is preserved in an equilibrium state which is not frozen, and the food is not damaged by ice crystals in this state; if the food is influenced by external interference factors such as low-temperature air blown out by the air duct in the state, the supercooled state is damaged, large-area freezing of the food is possible, the low-temperature non-freezing equilibrium state below the freezing point is damaged, but the latent heat phenomenon of temperature rise occurs in the damage process. Thus, although the instant freezing process includes four stages, the food is not damaged by ice crystals while the supercooling environment preparation in the first stage and the-5 ℃ maintaining operation in the fourth stage, and thus it is first necessary to judge the stage.
In actual control, the stage at which the current moment is determined by comparing the real-time temperature at the current moment with the preset temperature range of each stage can be generally determined in two ways. The four stages of the instant freezing procedure all have standard temperature curves as shown in fig. 1, and the temperatures of each stage are different, so that the stage can be determined according to the temperatures. The other control time length for the refrigerator to execute the instant freezing program can be obtained, and the control time length is compared with the preset thawing time length to determine the stage of the current moment. In the actual control process, the control duration of each stage is required, so that the current time can be determined in which stage according to the control duration after the instant freezing program is started.
When the current moment is in the supercooling import or supercooling maintenance stage, whether the instant freezing program is continuously executed is controlled according to the magnitude relation between the temperature difference value and the first preset value and the second preset value, wherein the first preset value is smaller than the second preset value. Namely, only when the second stage supercooling is introduced or the third stage supercooling is maintained, the freezing is caused by mistake due to the influence of external factors, 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, namely, a conventional temperature fluctuation, a temperature rise when the supercooled state is broken, and a new food being put into the freezing chamber. The temperature rise values in the three cases are different, wherein the rise value, i.e. the temperature difference, is the smallest when the conventional temperature fluctuates, generally does not exceed the first preset value, and the temperature difference is higher when the temperature rises when the supercooling state breaks, generally is between the first preset value and the second preset value, and the highest temperature difference is generally larger than the second preset value when new food is put in. Therefore, according to the temperature difference value, the first preset value and the second preset value, which condition is judged to be specific, so that accurate control is performed, and the food fresh-keeping effect is ensured. It will be appreciated that the first preset value and the second preset value may vary to some extent 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 stopping executing the instant freezing program when the temperature difference value is larger than the first preset value and smaller than the second preset value, and simultaneously controlling the freezing chamber to defrost and re-executing the instant freezing program after the thawing. The method comprises the steps of controlling the freezing chamber to defrost and re-executing the instant freezing program after defrosting, wherein the step of controlling the temperature in the freezing chamber to rise to a preset temperature and maintaining the preset defrosting time period and re-executing the instant freezing program. When the temperature difference is between the first preset value and the second preset value, the condition that the temperature rises when the supercooling state is destroyed is judged, and the food is frozen at the moment, so that the food needs to be thawed, and the instant freezing program is re-executed after the thawing.
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 indicated, the food fresh-keeping effect is not affected, and the instant freezing program is continuously executed.
And directly re-executing the instant freezing program when the temperature difference value is not smaller than a second preset value. When the temperature difference is not smaller than the second preset value, the new food is put into the freezing chamber, the new food is frozen instantaneously at the moment, the original food is not frozen, thawing is not needed, and the instantaneous freezing program is directly executed again.
Specific control is shown in fig. 3, the refrigerator enters an instant freezing program after operation, the first stage is a supercooling environment preparation stage, food is cooled or heated generally according to control of 2 ℃, the second stage is supercooling introduction, the temperature is controlled to gradually decrease for cooling, the third stage is in a supercooling maintaining state, and the fourth stage is a-5 ℃ maintaining operation; the first preset value T1 and the second preset value T2, and T1 is less than T2; when in the first stage, if food is put into the process, the temperature reduction process of the food in the program is not influenced, so that the process can be continued to run according to the program; when food is thrown in the second and third stages, the hot food damages the food in supercooled state, and the food fresh-keeping effect is affected; if the balance state is damaged by the external influence, the food is frozen into ice cubes in a large area, and the fresh-keeping effect after the program operation is greatly damaged; the sensor monitors the temperature in real time in the supercooling state, acquires the real-time temperature in the freezing chamber and obtains the temperature difference value T3 at the current moment, if T1 is smaller than T3 and smaller than T2, the supercooling is judged to be influenced by the outside to damage the balance state, the instant freezing program is not continuously operated and is unfrozen, and the program is re-executed after the unfreezing time reaches the preset unfreezing time T; if T2 is less than T3, then new food is judged to be put into, and the program can be directly re-executed without thawing, so that the situation that the food fresh-keeping effect cannot be achieved due to damage in the instant freezing supercooling state can be avoided.
According to the control method provided by the embodiment of the application, the temperature sensor detects failure or temperature rise of food input to judge, and after judgment, the program resumes executing to ensure the fresh-keeping effect of the refrigerator. The control method ensures complete supercooling state stage in instant freezing, and improves the fresh-keeping function of the product.

The temperature difference calculation module 42 is configured to obtain a temperature difference at the current time by subtracting the real-time temperature at the current time from the real-time temperature before the preset time.
The program execution control module 43 is used for controlling whether to continue executing the instant freezing program according to the temperature difference value. Specifically, when the temperature difference is greater than 0, the program execution control module 43 determines the stage at the current time, and the instant freezing program includes four stages of supercooling environment preparation, supercooling introduction, supercooling maintenance and-5 ℃ maintenance operation; if the current moment is in the supercooling import or supercooling maintenance stage, whether the instant freezing program is continuously executed is controlled according to the magnitude relation between the temperature difference and the first preset value and the second preset value, wherein the first preset value is smaller than the second preset value. The determining the stage of the current moment comprises the following steps: and comparing the real-time temperature at the current moment with the preset temperature ranges of all the stages to determine the stage at the current moment. Or, the control time length of the refrigerator for executing the instant freezing program is obtained, and the control time length is compared with the preset defrosting time length to determine the stage at the current moment.
