First embodiment, fig. 7 is a flowchart illustrating a control method of a refrigerator according to a first embodiment of the present invention. Wherein, the control method comprises the following steps:
and step 706, generating storage information or eating information of the food according to the quality grade.
The invention provides a control method of a refrigerator, which acquires information of food (for example, fresh meat products), judges the quality grade of the food according to the information of the food, and further generates storage information or eating information according to the quality grade. According to the embodiment of the invention, more favorable choices are provided for storage and eating of food according to the quality grade of the food, so that the food is ensured to have better quality during storage and eating, and the functions of the refrigerator are more extensive.
In the above embodiments, the quality of the food comprises one or a combination of: freshness, tenderness, juiciness, taste-producing substances.
In the embodiment, the quality of the food comprises but is not limited to freshness, tenderness, juiciness and flavoring substances, the eating quality and freshness of the food are graded through the information by using an intelligent model, the intelligent model is used for determining indexes of tenderness, juiciness, flavoring substances and the like of the food based on electrical impedance values of the food with different freshness under different frequency electrical signals, the intelligent model can be a model applying a pulse neural network, and the identification accuracy and the grading degree can be continuously optimized according to the accumulation of the use data of a user. Specifically, different numerical ranges of any information may correspond to different quality levels, or the quality levels may be determined by summing weights of the information.
In any of the above embodiments, the step 704 of determining the quality grade of the food according to the food information may specifically include: acquiring the food type, the electrical impedance value and the current temperature in the food information; determining an electrical impedance value range according to the food type; and determining the quality grade of the food according to the range of the electrical impedance value, the electrical impedance value and the current temperature.
In this embodiment, at least the following information is included in the food information: the food type, the electrical impedance value and the current temperature are integrated, the quality grade of the food is determined by integrating the food type, the electrical impedance value and the current temperature, and the accuracy of quality grade judgment is improved. The food type can be obtained by one or more modes of operation screen, voice recognition, image recognition and code scanning recognition, and the electrical impedance value and the current temperature can be measured by the detection probe.
In some embodiments, step 704, determining the quality grade of the food according to the food information, may further specifically include: acquiring food type, production time, electrical impedance value and current temperature in the food information; determining an electrical impedance value range according to the food type; and determining the quality grade of the food according to the range of the electrical impedance value, the production time, the electrical impedance value and the current temperature.

The quality grade of the food is determined by integrating the food type, the production time, the electrical impedance value and the current temperature, and the accuracy of quality grade judgment is improved.
In some embodiments, the quality grade of the food is determined according to the range of the electrical impedance value, the electrical impedance value and the current temperature, and the quality grade is corrected by using the production time. For example, when the food is the back leg meat of a pig, the electric impedance value range is from A1 to An (n is greater than or equal to 3), the electric impedance value range corresponds to the quality grade of 1, when the electric impedance value is detected to be A3 and the temperature is 15 ℃, the quality grade of the back leg meat of the pig is determined to be 1, and the deterioration speed of the back leg meat of the pig which is produced for 4 days is probably faster before the production time of the back leg meat of the pig is acquired to be 4 days, so the quality grade is adjusted to be 2 again (the quality grade is 1 grade is optimal, and then the grade is reduced in sequence).
In any of the above embodiments, step 706, generating storage information or consumption information of the food according to the quality grade, specifically including: and generating a recommended storage temperature and a recommended storage mode of the food or generating a recommended eating time and a recommended eating mode of the food according to the quality grade and a prestored storage temperature and quality time change curve.
In this embodiment, different storage temperatures correspond to different time variations in quality. For example, quality decreases more slowly with time when the temperature is lower, and decreases more rapidly with time when the temperature is higher. Therefore, the lower the quality grade of the food, the lower the temperature is selected to store the food so as to ensure that the food does not deteriorate rapidly, and the higher the quality grade of the food, the higher the temperature is selected to store the food, so that the power consumption of the refrigerator can be reduced when the weather temperature is higher. Alternatively, if the food below a certain quality level is set as inedible, the time corresponding to the quality level is taken as the recommended eating time, or the recommended eating method of the food, for example, if the current beef is level 1, a frying method is recommended if the current beef is eaten, or a stewing method is recommended if the food is eaten two days later. Therefore, fresh-keeping state monitoring, eating reminding and eating mode recommendation are provided for food.
