The preferred embodiments of the present application will be further described in detail below with reference to the accompanying drawings of the present specification.

Fig. 1 is a perspective view of a specific implementation method of a refrigerator 100 according to an embodiment of the present application.

Referring to fig. 1, the refrigerator of the present embodiment has an approximately rectangular parallelepiped shape. The external appearance of the refrigerator is defined by a storage chamber defining a storage space and a plurality of door bodies 130 provided on the storage chamber. The door body comprises a door shell positioned on the outer side of the refrigerator, an inner container positioned on the inner side of the refrigerator and a heat insulation layer between the door shell and the inner container. Typically, the insulation layer is filled with a foam material.

The storage compartment is a cavity having an opening, and generally, is divided to form a lower freezing compartment 110 and an upper refrigerating compartment 120. Each of the partitioned spaces may have a separate storage space. In detail, the freezing chamber 110 may have a plurality of separate storage spaces that can be drawer-opened or closed. The lower side of the refrigerating compartment 120 may be provided with a temperature varying chamber 121, which may be opened or closed in a drawer type.

In addition, the refrigerator has a controller for performing a refrigerator control method for controlling a refrigeration system of the refrigerator to provide cool air to the refrigerating chamber and the freezing chamber, and has a series of additional functions. In this application, the controller of refrigerator still is used for predicting the shelf life of the food material that the storeroom is stored, and the technical scheme of the embodiment of this application can improve the accuracy of predicting the food material shelf life.

The details of implementation of the technical solution of the embodiments of the present application are set forth in the following.

Fig. 2 is a flowchart illustrating a method for determining shelf life of food materials in a refrigerator according to an embodiment of the application. Referring to fig. 2, in the embodiment, the method for determining the shelf life of the food material in the refrigerator executed by the controller at least includes the following steps S210 to S230.

Step S210, determining the predicted storage quality guarantee period of the food materials in the storage chamber according to the types of the food materials stored in the storage chamber of the refrigerator.

First, the type of food material in the storage compartment of the refrigerator needs to be obtained, in one embodiment, the refrigerator may have an input device, the input device may be directly disposed on the refrigerator, or the input device may be an electronic device interconnected with the refrigerator, and the type of food material input by a user may be received through the input device. In one embodiment, an order for food material purchase uploaded by a user can also be received, and the food material type is obtained by identifying the food material in the order.

In further embodiments, when the user opens the door of the refrigerator, the refrigerator may also issue a question to obtain the type of the food material, such as whether the food material is to be stored, what kind of the stored food material, and the like.

The refrigerator can also obtain the type of the food material in another way, schematically, a camera in a refrigerator storage chamber can shoot a food material picture, and then the type of the food material can be identified according to the shot food material picture.

In another embodiment, the refrigerator may further include a plurality of food material tags, where the food material tags may be predefined or customized, and when storing food materials, the user attaches a tag for identifying a type to the food materials, so as to conveniently obtain the type of the food materials in the refrigerator.

After the refrigerator acquires the types of the food materials in the storage chamber of the refrigerator, the predicted storage shelf life of the food materials in the storage chamber is determined according to the types of the food materials.

Wherein the expected shelf life is different from the shelf life of the food material, the expected shelf life being the freshness date of the food material of the category stored in the refrigerator storage compartment. As will be readily appreciated, shelf life is expected to be closely related to the environment within the refrigerator storage compartment.

In one embodiment, the environmental information in the storage room may be acquired after the type of food material is acquired. The environmental information in the storage room may include one or more of humidity information, temperature information, oxygen content, etc., so as to obtain various environmental information stored in the food material, thereby obtaining an actual environment in the storage room through the various environmental information. After the type of the food material and the actual environment of the refrigerator are determined, the expected storage shelf life of the food material of the type in the actual environment can be obtained. Illustratively, the expected shelf life of the food material of the category in the actual environment can be obtained from historical data in the internet. The estimated storage shelf life can be corrected according to the actual storage condition, so that the subsequent data are more accurate.

In some embodiments, determining the expected storage shelf life of the food material of the category according to the category of the food material and the environmental information may further include: and acquiring the predicted storage shelf life of the food material of the variety under the environmental information from a database, wherein the database has a corresponding relation between the combination of the food material of the variety and the environmental information and the predicted storage shelf life.

Step S220, determining the quality guarantee period deviation value of the food material according to the change situation of the environment in the storage chamber during the storage period of the food material.

Since the expected shelf life is closely related to the environment inside the refrigerator storage room, the shelf life deviation value of the food material can be determined by monitoring the change of the environment inside the storage room. The shelf-life deviation value is a deviation value from the expected shelf life in step S210.

It is first necessary to acquire the changes in the environment inside the storage room. Specifically, the temperature information in the storage chamber can be acquired by a temperature sensor provided in the storage chamber, so that the change of the temperature in the storage chamber during the storage period of the food material of the type can be obtained. As can be readily appreciated, shelf-life deviation values will increase in the case of severe temperature changes. The number of temperature sensors may be one or more. Accordingly, the humidity change information in the storage chamber may be acquired by a humidity sensor provided in the storage chamber, the oxygen concentration change information in the storage chamber may be acquired by an oxygen concentration sensor provided in the storage chamber, and the like.

After obtaining the variation of one or more shelf-life influencing factors, the shelf-life deviation value of the food material can be comprehensively obtained according to the influence of the variation of each shelf-life influencing factor on the shelf life of the food material.

Since food materials generally have a longer shelf life in low temperature environments, in one embodiment, the environmental information includes at least temperature information, such that after determining the type of food material, based on the temperature within the storage compartment, the expected shelf life of the type of food material at that temperature is determined.

And step S230, calculating the quality guarantee period of the food material according to the predicted storage quality guarantee period and the quality guarantee period deviation value.

After obtaining the predicted shelf life and the shelf life deviation value, the shelf life of the food material is easily obtained.

Therefore, after the food materials are stored in the refrigerator, the expected storage quality guarantee period of the food materials is firstly determined, in the storage process of the food materials, the quality guarantee period deviation value is obtained according to the actual environment in the refrigerator, the expected storage quality guarantee period is corrected, and the quality guarantee period corresponding to the food materials and the actual storage environment is obtained, namely, the change condition of the environment of the storage chamber in the refrigerator is considered, so that the obtained quality guarantee period of the food materials is more accurate.

FIG. 3 is a flowchart of an exemplary embodiment of step S210 in FIG. 2. Referring to fig. 3, in the embodiment, the step S210 at least includes the following steps S310 to S350.

Step S310, acquiring one or more shelf life influencing factors of the food materials of the type in the storage chamber according to the type of the food materials.

Schematically, if the food material is fruit or vegetable, the greater the humidity, the more beneficial is the storage of the food material; if the food materials are dry goods, when the humidity is too high, the dry goods become damp and go bad, the taste is not affected, and the food materials are more harmful to health; if the food material is canned dairy product, the humidity is slight for the canned dairy product. Therefore, different influencing factors can be selected according to the variety of the food materials to estimate the shelf life.

Step S320, obtaining a variation corresponding to each of the one or more shelf life influencing factors.

And step S330, determining the shelf life deviation value corresponding to the influence factor according to the corresponding relation between the change condition corresponding to the preset influence factor and the shelf life deviation value.

After obtaining the type of food material, a shelf-life deviation value for the food material may be determined based on a change in one or more shelf-life affecting factors within the storage compartment. Specifically, the shelf-life deviation value can be determined according to the corresponding relationship between the change condition corresponding to the preset influence factor and the shelf-life deviation value. For example, pork has a projected shelf life of 2 days at 4 ℃ and 42 days at-18 ℃. The effect of temperature variations on shelf-life deviation values can be obtained depending on the actual temperature inside the storage compartment versus 4 c or-18 c. In one embodiment, in the case that the expected storage shelf life is derived from the temperature inside the refrigerator when the food material is stored in the refrigerator, the shelf life deviation value corresponding to the temperature change may be determined according to the change of the temperature inside the refrigerator during the storage of the food material with respect to the temperature inside the refrigerator when the food material is stored in the refrigerator. For example, the ratio of the abnormal temperature time to the total storage time can be obtained according to the temperature curve, and the longer the abnormal temperature time is, the larger the quality guarantee period deviation value is.

Step S340, obtaining the influence weight of each influence factor on the quality guarantee period of the food material.

Step S350, calculating the quality guarantee period deviation value of the food material according to the quality guarantee period deviation value corresponding to each of the one or more influence factors and the influence weight corresponding to each influence factor.

As described above, after obtaining the variation of one or more shelf-life influencing factors, the shelf-life deviation value of the food material is obtained comprehensively according to the influence of the variation of each shelf-life influencing factor on the shelf-life deviation value of the food material of the category.

Specifically, the influence weights of different influencing factors on different kinds of food materials may be different. Therefore, in the present embodiment, the influence weight of each influence factor on the shelf life of the food material is also considered. For example, it is experimentally determined that the weight of the influence of temperature on a certain type of food material is N1, the weight of the influence of humidity on the certain type of food material is N2, and when the shelf life deviation value corresponding to temperature is T1 and the shelf life deviation value corresponding to humidity is T2, the deviation value T of the comprehensive environmental factors is T1T 1+ N2T 2.

Therefore, the quality guarantee period deviation value of the food material can be calculated through one or more quality guarantee period influence factors and the influence weight corresponding to each influence factor. The method can comprehensively consider the influence of various influence factors in the refrigerator on the quality guarantee period, so that the quality guarantee period of the food material can be accurately estimated.

In some embodiments, the shelf-life deviation value of the food material may also be determined according to a change of an environment in the storage compartment relative to an adaptive storage environment corresponding to the type of food material, that is, a deviation of an actual storage environment relative to the adaptive storage environment. Specifically, the adapted storage environment of the food material generally enables the shelf life of the food material to be longest. On the one hand, the corresponding estimated storage shelf life is easy to obtain when the food material is stored in the adaptive storage environment, on the other hand, the shelf life of the food material is correspondingly shortened according to the deviation condition of the actual storage environment relative to the adaptive storage environment, the calculation is convenient, and the accuracy is high. In some embodiments, the adapted storage environment includes at least a suitable storage temperature, and therefore, it is desirable to monitor the temperature within the storage compartment.

Further, in another embodiment, when the difference between the monitored temperature in the storage chamber and the adaptive storage temperature of the food material is greater than the preset deviation value, a storage risk prompt can be sent, so that a user can be timely reminded to take corresponding operation beneficial to food material storage, and the shelf life of the food material is prolonged.

In some embodiments, the environmental information of the environment within the storage compartment includes one or more of temperature information, humidity information, microbiological content information, and oxygen content information. Specifically, different environmental information has different influence degrees on different types of food materials, and in general, the influence degrees of temperature information, humidity information, microorganism content information, oxygen content information and shelf life are higher. Corresponding hardware can be arranged in the refrigerator to obtain the environment information, the quality guarantee period can be estimated according to the obtained environment information, and the accuracy of the estimated quality guarantee period can be improved.

In some embodiments, after calculating the shelf life of the food material from the projected shelf life and the shelf life deviation value, the method of determining the shelf life of food material in a refrigerator further comprises the steps of:

establishing a quality guarantee period database of food materials stored in a storage room, wherein the quality guarantee period database has a corresponding relation between the food materials and the quality guarantee periods of the food materials;

sending out the expiration reminding of the expiration date of the food materials to be expired according to the expiration date database.

Specifically, a storage unit may be disposed in the controller of the refrigerator or in the electronic device connected to the refrigerator, and the storage unit is used to store a shelf life database of the food material in the storage chamber, where the shelf life database is used to store the food material and the corresponding relationship between the shelf lives of the food materials. According to the shelf life database, reminders for food materials whose shelf life is about to expire may be set, e.g. reminders made 2 days in advance, so that the user is informed about the fact for orchestration.

Since some food materials have a short expected shelf life, even only one or two days, in some embodiments, after establishing the shelf life database of food materials stored in the storage compartment, the method for determining shelf life of food materials in a refrigerator further comprises the steps of: the shelf life database is updated at preset time intervals, wherein the preset time intervals are less than 24 hours. Therefore, the shelf life reminding device can give out the shelf life reminding at least once every day to prevent certain food materials from being reminded of being rotten.

In one embodiment, further, the issuing time interval of the shelf life may be determined according to the expected storage shelf life of the food material, for example, if the food material with longer shelf life is less likely to deteriorate in a short period, the reminding time interval may be increased, thereby saving energy. Further, in some embodiments, after the shelf life database is updated, the food material and the shelf life corresponding to the food material are sent to a predetermined electronic device, such as a mobile phone, so that the user can check the food material and the shelf life corresponding to the food material conveniently. In another embodiment, the monitored change condition of the environmental information of the refrigerator can be sent to a preset electronic device, so that a user can know the operation condition of the refrigerator more comprehensively.
