Preferred embodiments of the present application are further elaborated below in conjunction with the 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 appearance of the refrigerator is defined by a storage compartment defining a storage space and a plurality of door bodies 130 provided on the storage compartment. The door body comprises a door shell positioned at the outer side of the refrigerator, an inner container positioned at the inner side of the refrigerator and a heat insulation layer between the door shell and the inner container. Typically, the insulating layer is filled with a foam material.
The storage chamber is a cavity having an opening, and is divided into a lower freezing chamber 110 and an upper refrigerating chamber 120 in general. 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 refrigerating chamber 120 may be provided with a temperature varying chamber 121 at a lower side thereof, and the temperature varying chamber 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 refrigerating system of the refrigerator to supply cool air to a refrigerating chamber and a freezing chamber, and a series of additional functions. In the application, the refrigerator controller is further used for estimating the quality guarantee period of food materials stored in the storage room, and the technical scheme of the embodiment of the application can improve accuracy of estimating the quality guarantee period of the food materials.
Implementation details of the technical solutions of the embodiments of the present application are set forth in detail below.
Fig. 2 is a flowchart of a method of determining a shelf life of food in a refrigerator according to an embodiment of the present application. Referring to fig. 2, in the embodiment, the method for determining the shelf life of food in the refrigerator performed by the controller at least includes the following steps S210 to S230.
Step S210, according to the type of food materials stored in the storage chamber of the refrigerator, determining the expected storage shelf life of the food materials in the storage chamber.
First, the type of food material in the storage chamber of the refrigerator needs to be obtained, in one embodiment, the refrigerator may have an input device, which may be directly provided on the refrigerator, or the input device may be an electronic device interconnected with the refrigerator, and may receive the type of food material input by a user through the input device. In one embodiment, an order for food material purchase uploaded by the user may also be received, and the type of food material is obtained by identifying the food material in the order.
In another embodiment, the refrigerator may also issue questions such as whether food materials are to be stored, what kind of food materials are stored, etc. to obtain the kind of food materials when the user opens the refrigerator door.
The refrigerator can also acquire the types of food materials in another mode, illustratively, the food material pictures can be shot through the camera in the refrigerator storage chamber, and then the types of the food materials can be identified according to the shot food material pictures.
In other embodiments, the refrigerator may further have a plurality of food material tags, and the food material tags may be predefined or customized, and when storing food materials, a user attaches a tag for identifying a type to the food materials, so that the type of food materials in the refrigerator may be conveniently obtained.
After the refrigerator obtains the type of food materials in the storage chamber of the refrigerator, the expected storage shelf life of the food materials in the storage chamber is determined according to the type of the food materials.
Wherein the expected shelf life is different from the shelf life of the food material, and the expected shelf life refers to the preservation period of the food material in the refrigerator storage room. As will be readily appreciated, shelf life is expected to be closely related to the environment within the refrigerator compartment.
In one embodiment, the environmental information in the storage chamber may be acquired after the type of food material is acquired. The environmental information in the storage chamber 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 chamber through the various environmental information. When the kind of food material and the actual environment of the refrigerator are determined, the expected shelf life of the kind of food material under the actual environment can be obtained. Illustratively, the expected shelf life of the food material of the category in the actual environment may be obtained from historical data in the internet. The expected storage shelf life can be corrected according to the actual storage condition, so that the follow-up data is more accurate.
In some embodiments, determining the expected shelf life of the food material of the category according to the category of the food material and the environmental information may specifically further include: and obtaining the expected storage shelf life of the food materials of the types under the environment information from a database, wherein the database is provided with the corresponding relation between the combination of the types of the food materials and the environment information and the expected storage shelf life.
Step S220, determining a quality guarantee period deviation value of the food materials according to the change condition of the environment in the storage room in the food material storage period.
Since the shelf life is expected to be closely related to the environment in the storage compartment of the refrigerator, the value of the shelf life deviation of the food material can be determined by monitoring the change of the environment in the storage compartment. The shelf life deviation value is a deviation value with respect to the expected shelf life in step S210.
First, it is necessary to acquire the change of the environment in the storage room. Specifically, the temperature information in the storage chamber can be acquired by a temperature sensor provided in the storage chamber, and the change in the temperature in the storage chamber during the storage period of the food of this kind can be obtained. It is readily understood that in case of severe temperature changes, the shelf life deviation value will increase. The number of temperature sensors may be one or more. Accordingly, humidity change information in the storage chamber may be acquired by a humidity sensor provided in the storage chamber, 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 the change condition of one or more shelf life influencing factors is obtained, the shelf life deviation value of the food materials can be comprehensively obtained according to the influence of the change condition of each shelf life influencing factor on the shelf life of the food materials.
Because food materials are typically kept fresh longer in a low temperature environment, in one embodiment, the environmental information includes at least temperature information, such that after a type of food material is determined, the expected shelf life of the type of food material at that temperature is determined based on the temperature within the storage compartment.
Step S230, calculating the shelf life of the food material according to the expected shelf life and the shelf life deviation value.
After the expected shelf life and the shelf life deviation value are obtained, the shelf life of the food material is easy to obtain.
Therefore, after the food material is stored in the refrigerator, firstly, the expected storage shelf life of the food material is determined, and in the storage process of the food material, the shelf life deviation value is obtained according to the actual environment in the refrigerator, so that the expected storage shelf life is corrected, and the shelf life corresponding to the food material and the actual storage environment is obtained, that is, the change condition of the environment of a storage room in the refrigerator is considered in the embodiment of the application, so that the obtained shelf life of the food material is more accurate.
Fig. 3 is a flow chart of an exemplary embodiment of step S210 in fig. 2. Referring to fig. 3, in this embodiment, the step S210 at least includes the following steps S310 to S350.
Step S310, according to the type of the food material, one or more shelf life influencing factors of the food material in the storage chamber are obtained.
Illustratively, if the food material is fruit or vegetable, the greater the humidity, the more beneficial it is to the storage of the food material; if the food material is dry goods, the dry goods are damped and deteriorated and tainted to be caked when the humidity is too high, so that the taste is not only affected, but also the eating is more harmful to health; if the food material is a canned dairy product, the humidity is less than for the canned dairy product. Therefore, different influencing factors can be selected according to the types of the food materials to estimate the quality guarantee period.
Step S320, obtaining the change conditions corresponding to the one or more shelf life influencing factors respectively.
Step S330, determining the quality guarantee period deviation value corresponding to the influence factor according to the corresponding relation between the change condition corresponding to the preset influence factor and the quality guarantee period deviation value.
After the type of food material is obtained, a value of the shelf life deviation of the food material may be determined based on a change in one or more shelf life influencing factors within the storage compartment. Specifically, the quality guarantee period deviation value can be determined according to the corresponding relation between the change condition corresponding to the preset influence factor and the quality guarantee period deviation value. For example, pork has an expected shelf life of 2 days at 4℃ and 42 days at-18℃. The effect of temperature changes on the value of the shelf life deviation can be obtained depending on the change in the actual temperature in the storage compartment relative to 4 c or-18 c. In one embodiment, in the case where the expected shelf life is obtained according to the temperature in the refrigerator when the food 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 in the refrigerator during the storage period of the food relative to the temperature in the refrigerator when the food is stored in the refrigerator. For example, the ratio of the temperature anomaly time to the total storage time length can be obtained according to the temperature curve, and the longer the temperature anomaly 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 change condition of one or more shelf life influencing factors, the shelf life deviation value of the food material is comprehensively obtained according to the influence of the change condition of each shelf life influencing factor on the shelf life deviation value of the food material.
In particular, the impact weights of different impact 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, according to experiments, 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 type of food material is N2, and when the shelf life deviation value corresponding to the temperature is T1 and the shelf life deviation value corresponding to the humidity is T2, the deviation value T of the combination of the environmental factors is obtained, where t=n1×t1+n2×t2.
Therefore, the quality guarantee period deviation value of the food material can be calculated through one or more quality guarantee period influence factors and influence weights corresponding to the influence factors. The method can comprehensively consider the influence of various influencing factors in the refrigerator on the shelf life, so that the shelf life of the food materials can be accurately estimated.
In some embodiments, the shelf life deviation value of the food material may also be determined according to the change condition of the environment in the storage room relative to the adaptive storage environment corresponding to the type of food material, that is, the deviation condition of the actual storage environment relative to the adaptive storage environment. Specifically, the adaptive storage environment of the food material generally can maximize the fresh-keeping period of the food material. On one hand, the corresponding expected storage shelf life of the food is easy to obtain when the food is stored in the adaptive storage environment, and on the other hand, the shelf life of the food is correspondingly shortened according to the deviation condition of the actual storage environment relative to the adaptive storage environment, so that 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 adapted storage temperature of the food material is greater than the preset deviation value, a storage risk reminder may also be sent, so that the user may be reminded to take corresponding operations beneficial to food material storage in time, so as to prolong the shelf life of the food material.
In some embodiments, the environmental information of the storage room environment includes one or more of temperature information, humidity information, microorganism content information, and oxygen content information. Specifically, the different environmental information has different influence degrees on different kinds of food materials, and in general, the temperature information, the humidity information, the microorganism content information and the oxygen content information have higher influence degrees with the shelf life. Corresponding hardware can be arranged in the refrigerator to acquire the environmental information, and the quality guarantee period is estimated according to the acquired environmental information, so that the accuracy of estimating the quality guarantee period can be improved.
In some embodiments, after calculating the shelf life of the food material from the expected shelf life and the shelf life deviation value, the method of determining the shelf life of the food material in the refrigerator further comprises the steps of:
establishing a quality guarantee period database of the food materials stored in the storage room, wherein the quality guarantee period database has the corresponding relationship of the food materials and the quality guarantee period of the food materials;
and sending a expiration date prompt of the food material to be expired according to the expiration date database.
Specifically, a storage unit may be provided in a controller of the refrigerator or in an electronic device connected to the refrigerator, and the storage unit is configured to store a shelf life database of food materials in the storage chamber, where the shelf life database is configured to store the corresponding relationship between the food materials and shelf life of the food materials. According to the shelf life database, a reminder of food materials about to expire in shelf life, for example, a reminder of 2 days in advance, can be set so that the user knows to arrange for overall.
Since some food items are expected to have a short shelf life, even for only one or two days, in some embodiments, after establishing the shelf life database of food items stored in the storage compartment, the method of determining shelf life of food items in the 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 can be sent out at least once every day, so that the phenomenon that certain food materials are not reminded to be damaged already can be prevented.
In one embodiment, the time interval for emitting the shelf life may be further determined according to the expected shelf life of the food, for example, if the food with a longer shelf life has a smaller possibility of deterioration in a short period, the time interval for reminding may be increased, so as to achieve energy saving. Further, in some embodiments, after the expiration date database is updated, the food material and the expiration date corresponding to the food material are sent to a predetermined electronic device, such as a mobile phone, so as to facilitate the user to check. In other embodiments, the monitored change condition of the environmental information of the refrigerator may be sent to a preset predetermined electronic device, so that a user may more comprehensively understand the operation condition of the refrigerator.
