In the present invention, the refrigerator 10 may receive the trip time interval information of the user and the expiration time of the food, thereby determining whether the expiration time of the food is within the trip time interval. If in the travel time interval, the reminding device can timely prompt the user to eat, so that food overdue and waste are prevented. Therefore, the invention can effectively reduce the waste of food caused by the trip of the user, can more intelligently plan the diet and the life of the user, and brings great life convenience to the user.
In an embodiment, the step of "acquiring the travel time interval" includes:
the ticket booking information is acquired by communicating with the mobile terminal;
acquiring a travel date from travel booking information, and acquiring a return date from return booking information;
the line time interval is calculated.
At present, when a user orders tickets on a mobile terminal, namely a mobile phone, the user usually orders the tickets on the mobile terminal, so that the refrigerator 10 is in communication connection with the mobile phone, and the refrigerator 10 can obtain ticket ordering information in the ticket ordering APP in the mobile phone. And further acquiring a travel booking date and return booking information, so that the travel date and the return date are acquired, and a travel time interval when the user is not at home is set between the travel date and the return date.
Or, in another embodiment, the step "acquiring the travel time interval" includes:
communicating with the mobile terminal and acquiring schedule information;
acquiring a trip date and a return date;
the line time interval is calculated.
Or, the mobile terminal of the user usually has an APP of a schedule class, and in the APP of the schedule class, the user actively records a trip in the APP of the schedule class. Therefore, the refrigerator 10 is in communication connection with the mobile phone, so that the refrigerator 10 can also obtain the travel date and the return date displayed in the schedule type APP, and a travel time interval when the user is not at home is between the travel date and the return date.
Two ways of obtaining the travel time interval are introduced above, and the following describes in detail the obtaining of the expiration time of the food in the refrigerator 10.
The step of acquiring the expiration time of the food in the refrigerator 10 includes:
recognizing food put in the refrigerator 10;
acquiring the storing time of a certain food stored in the refrigerator 10;
the fresh-keeping time of the food is called;
the expiration time of the food is calculated.
Therefore, after the storage time and the preservation time length are known, the preservation time length can be added on the basis of the storage time, and the expiration time of the food can be obtained.
Wherein the step of "recognizing food put in the refrigerator 10" includes:
carrying out image recognition on food to obtain and record food names; or receiving and recording the food name input by the user; alternatively, a tag on the food is scanned to obtain and record the food name.
In the above record of food names, three specific embodiments are provided. The first is to arrange a camera in the refrigerator 10 or outside the refrigerator 10, and to photograph and identify food to obtain the name of the food; secondly, the screen 1 of the refrigerator 10 is arranged to accept the food names input by the user through typewriting, or a sound pickup device is arranged outside the refrigerator 10 to acquire the food names input by the user through voice; the third is to provide a scanning camera outside the refrigerator 10 to obtain the name of the food by scanning the label on the food. The food names are obtained in all three ways and recorded in the memory inside the refrigerator 10. Of course, the present invention is not limited to the above three modes, and other modes can also achieve the requirement of the present invention if the function of recording the food stored in the refrigerator 10 can be achieved.
Of course, in the process of obtaining the food name, the storage time of the food is also recorded, so that the storage time of each food can be conveniently obtained.
Specifically, the step of calling the fresh-keeping time of the food comprises the following steps:
scanning a label on food to obtain the freshness keeping time; or the freshness keeping time of the food in the refrigerator 10 is obtained from a memory or cloud query of the refrigerator 10.
Therefore, if the food is labeled with the label, the label can be scanned by the scanning camera on the refrigerator 10 to obtain the fresh-keeping time of the food; if the food is not labeled, the shelf life, i.e., the freshness duration, of the food in the refrigerator 10 can be queried from the memory or cloud of the refrigerator 10.
Further, the step of "issuing a reminder to use the food" includes:
when the activation information of the refrigerator 10 is received, controlling the screen 1 of the refrigerator 10 to display the image or the name of the food, or controlling the sound 2 of the refrigerator 10 to prompt the name of the food by voice; or push the image or name of the food to the mobile terminal.
Three ways of recommending food to the user are provided in the present invention, wherein the first and second are prompting on the refrigerator 10, respectively, displaying on the screen 1 and prompting through the speaker 2. The third is to display in the mobile terminal of the user, for example, the refrigerator 10 is connected to the mobile phone of the user in a communication manner, and the image or name of the food can be pushed to the mobile phone of the user.
In addition, considering that the user uses the food which is about to expire before going out, the user needs to purchase the food before returning.
Specifically, the method for reminding food in the refrigerator 10 further includes:
acquiring food information to be purchased within a time period T before a return date;
and pushing a purchase prompt of the food to be purchased to the mobile terminal.
In the T time period before the user returns home, the user is reminded to purchase food, and the purchasing way comprises online purchasing and the like, so that after the user returns home, the food can be express delivered to home, and the user can enjoy fresh food. Of course, the T period may be adjusted for different food types. For example, fruits and vegetables, etc., the T period may be one day, snack nuts, etc., and the T period may be one week.
The food to be purchased by the user is generally the common food of the user and is the common food not stored in the refrigerator 10. Thus, the step of "acquiring the food purchase demand information" includes:
obtaining common food;
judging the storage capacity of a certain common food in the refrigerator 10;
acquiring a storage threshold U of the common food;
and if the storage amount of the common food is lower than the corresponding storage threshold value U, judging that the common food is the food needing to be purchased.
Further, it is necessary to determine the food that is commonly used by the user. The steps of obtaining common food comprise:
recording the food each time it is selected or removed from the refrigerator 10;
calculating the number of uses Na of each food selected or taken out in the time period A;
and if the using frequency Na of a certain food in the time period A exceeds the using threshold value C, judging the food to be the common food. That is, the number of times Na of use of a certain food by the user in a certain period a is determined, and if the number of times Na of use is large and exceeds the use threshold C, it can be said that the user likes the food and eats it many times. Thus, if the user likes the general food but there is no storage in the refrigerator 10, the user can be reminded to purchase the general food before the user returns.
The step of recording the food selected or taken out of the refrigerator 10 at a time is a process of recording the favorite food of the user, and the step of recording the food selected or taken out of the refrigerator 10 at a time includes: the food selected by the user each time is recorded. The user can select food on the screen 1 of the refrigerator 10, so that the refrigerator 10 can further understand the user's taste and calculate the commonly used food.
Alternatively, the step of "recording the food each time it is selected or taken out of the refrigerator 10" includes:
recording the food taken each time;
the step of recording the food taken out each time specifically comprises the following steps:
shooting the inside of the refrigerator 10 to obtain a pre-taking photo;
identifying name information of the food in the photo before taking;
after receiving the information that the refrigerator 10 is closed, shooting the inside of the refrigerator 10 again to obtain a taken picture;
identifying the name information of the food in the taken picture;
judging name information of food lacking relative to the picture before taking in the picture after taking;
the missing food was recorded as food taken out.
The pre-taking picture and the post-taking picture are obtained by taking pictures in the refrigerator 10, and the food in the pictures is recognized and the name information of the food is obtained, so that the food taken out by the user during the door opening process can be obtained by comparison.
In summary, the present invention provides a method for reminding food in a refrigerator 10, and in the present invention, the refrigerator 10 may receive trip time interval information of a user and expiration time of the food, so as to determine whether the expiration time of the food is within the trip time interval. If in the travel time interval, the reminding device can timely prompt the user to eat, so that food overdue and waste are prevented. Therefore, the invention can effectively reduce the waste of food caused by the trip of the user, can more intelligently plan the diet and the life of the user, and brings great life convenience to the user. In addition, before the return date of the user, the refrigerator 10 can issue a food purchase reminder to the user, so that the user can plan the food before the return date, and the life of the user is more comfortable.
