DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

In order to make those skilled in the art better understand the technical solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below with reference to the drawings in the embodiment of the present invention, and it is obvious that the described embodiment is only a part of the embodiment of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The refrigerator food material management method provided by the embodiment of the invention can record the use data of the user and automatically set the storage priority weight of each article according to the characteristics of the use data of the user, the price of the article and the like.

First embodiment

Referring to fig. 1, a method for managing refrigerator food materials according to an embodiment of the present invention includes:

identifying a kind of an article in the refrigerator;

obtaining the storage times of the articles in a preset time period;

and matching the storage priority weight of the item according to the storage times.

The preset time period may be within a few months, or may be a certain time period of the history, for example, a few months of the last year, from the time when the user uses the refrigerator to the time when the user obtains the storage times of the articles. The storage priority weight indicates the priority level at the time of storing the article, and the refrigerator adjusts the storage parameters such as temperature and humidity in the compartment according to the storage priority weight of the article. The higher the preservation priority weight of an item, the higher the importance of the item, and the closer the final storage parameter in the refrigerator is to the optimal storage parameter of the item. Specifically, the retention priority weight is in the range of 1-10. And a food material information base is preset in the refrigerator or the cloud, and the preset food material information base is inquired according to the storage times to obtain the storage priority weight. Therefore, the storage habit of the user in the preset time period is judged according to the storage times of the articles, and the storage priority weight of the articles is matched conveniently and quickly.

Further, the step of "identifying the kind of the article in the refrigerator" includes:

receiving an opening signal of a refrigerator door body;

acquiring the types of articles stored in the refrigerator before the door body is opened;

identifying the type of the deposited article and the type of the taken out article;

receiving a closing signal of the door body;

and identifying the types of articles in the refrigerator after the door body is closed.

The method for identifying the type of the article can be various and can be implemented, the type of the article is identified through the input of a user by utilizing an input device arranged on a refrigerator or a mobile terminal, and the input device can be a physical key or a touch screen and can also be a voice input module; in some optional embodiments, the automatic identification device may be further used to identify the type of the article, specifically, the image identification device may be set in the refrigerator, when a user stores the article, the user takes a picture of the article through the camera and uploads the picture to the cloud database, and obtains information of the article through image comparison, or the RFI D identification device is set in the refrigerator, an identification code is set in the article, and the identification code is identified by the identification device to obtain information of the article.

And after the door body is closed, the types of the articles in the refrigerator are the types of the articles in the refrigerator before the door body is opened, the types of the taken-out articles are deleted, and the types of the put-in articles are increased.

Of course, it may be implemented that the types of the articles in the refrigerator after the door of the refrigerator is closed are firstly identified, and then the types of the articles in the refrigerator after the door is closed are compared with the types of the articles in the refrigerator before the door is opened, so as to obtain the types of the stored articles and the types of the taken articles. Specifically, for example, a camera in the refrigerator is used to capture pictures of the user in the refrigerator before and after the user accesses the articles, and the pictures are uploaded to the cloud for comparison, so as to obtain the types of the articles stored in the refrigerator, and the types of the articles taken out of the refrigerator.

Further, after identifying the type of the stored item, the food material management method further includes:

judging whether the type of the stored article is the same as that of the taken article in a preset period or not;

if yes, prompting a user to confirm whether the stored article is the taken article within a preset period;

if the user selects no, recording the types of the stored articles and the storage data.

The preset period is a period of time before the user deposits the article, and specifically, the preset period may be four to eight hours before the user deposits the article. By judging whether the article is taken out within the preset period, the user is prevented from repeatedly recording and storing data of the same article due to the fact that only part of the article is used and the article is put into the refrigerator after the article is taken out.

Further, in an embodiment, after identifying the category of the deposited item, the method further includes:

recording the deposit time of the deposited article;

wherein, acquire in the preset time quantum deposit number of times of article, include:

acquiring the storage time of the article in a preset time period;

and calculating the storage times of the articles in a preset time period, wherein the storage times in the preset time period are equal to the number of the storage times in the preset time period. In a specific example, when a user puts bananas into a refrigerator, the storage time of the bananas is recorded, when the storage times in one month need to be acquired, the storage time of the bananas recorded in one month is called, and the number of the storage times is the storage times of the bananas in one month.

In another embodiment, after identifying the type of the item being deposited, the method further comprises:

acquiring historical storage times of the stored articles;

and calculating and updating the storage times of the stored articles, wherein the storage times are equal to the historical storage times plus one.

The historical storage times are storage times of the articles stored in the refrigerator when the articles are placed in the refrigerator by a user. If the user puts in a certain article for the first time, the historical storage frequency of the article is 0, and the storage frequency is updated to 1 after the article is put in. Therefore, the storage times of the articles are directly recorded when the articles are stored, and the storage times of the articles can be directly called after the types of the articles in the refrigerator are identified.

Further, in one embodiment, matching the preservation priority weight of the item according to the number of deposits comprises:

and querying a preset food material information base according to the frequency ranking, and matching the storage priority weight of the article, wherein the food material information base stores the storage priority weight corresponding to each frequency ranking.

The large number of times of storage of the articles indicates that the articles are articles frequently stored in the refrigerator, and it can be determined that the user has a high preference or importance for the articles, and therefore, articles with a large number of times of storage, that is, articles with a higher rank of times, can be matched with a higher storage priority weight. Of course, the storage frequency is high when the storage times are large, the storage time of the user is short, the consumption rate of the articles is high, and the preservation requirement of the user is low, so that the low preservation priority weight can be matched with the articles with the large storage times.

Further, in an embodiment, after matching the storage priority weight of the item according to the storage times, the method further includes:

acquiring the optimal storage parameters of the articles in the refrigerator;

calculating an optimal compartment parameter based on the optimal storage parameter and the preservation priority weight for each item.

Wherein, the optimal storage parameter is one or more of the optimal storage temperature, the optimal storage humidity and the optimal storage gas concentration, and when the related parameters of the storage environment of the article are set as the optimal storage parameters, the storage time of the article is the longest. A food material information base is preset in a database or a cloud database of the refrigerator, and optimal storage parameters corresponding to each article are stored in the food material information base.

The optimal compartment parameter is the parameter which can achieve the optimal fresh-keeping effect according to the requirements of users when the parameter in the refrigerator compartment is adjusted to the parameter.

In one embodiment, the best storage parameter for storing the item with the highest priority weight may be set as the best compartment parameter, so that the most important item is stored preferentially. In another embodiment, the optimal compartment parameter may be calculated according to the storage priority weight, and specifically, the optimal compartment parameter is F = (A1F 1+ A2F2+ … + AnFn)/(A1 + A2+ … + An), where F is the optimal compartment parameter, an is the storage priority weight of each item, and Fn is the optimal storage parameter of each item. The optimal compartment parameters are calculated by combining the storage priority weight and the optimal storage parameters of each article, so that the optimal fresh-keeping effect can be realized according to the requirements of users.

Second embodiment

The refrigerator food material management method provided by the second embodiment of the present invention is different from the first embodiment in that, in the present embodiment, the refrigerator food material management method matches the preservation priority weights of the items according to the prices of the items and the number of times of storage within a preset time period. Referring to fig. 2, the method for managing the refrigerator food materials specifically comprises the following steps:

identifying a kind of an article in the refrigerator;

acquiring the price of the article and the storage times within a preset time period;

matching a second saved priority weight for the item according to the price;

matching a preservation priority weight of the item according to the first preservation priority weight and the second preservation priority weight.

Wherein the price of the article can be the unit price of the article or the total price of the article. For a specific method for identifying the kind of the article and obtaining the number of times the article is stored in a preset time period, refer to the first embodiment.

The storage priority weight of the article is as follows: a = n1A1+ n2A2. Wherein, a is the saving priority weight, A1 is the first saving priority weight, A2 is the second saving priority weight, and n1 and n2 are preset coefficients. n1 and n2 may be adjusted according to user requirements, for example, when the price storage frequency is considered as important, n1= n2 may be selected, and when the price factor is considered as important than the storage frequency, n1> n2 may be selected, and of course, n1 and n2 may be calculated by comprehensively considering other factors such as storage time. A food material information base is preset in the refrigerator or the cloud, and the preset food material information base is inquired according to the storage times and the price to obtain a first storage priority weight and a second storage priority weight. Therefore, the storage priority weight of the goods is calculated by comprehensively considering the price and the storage times of the goods, the accuracy of the storage priority weight is improved, and the problems that the valuable goods are low in storage priority weight and insufficient in preservation due to the fact that the storage times are small are prevented.

Further, obtaining the price of the item includes:

detecting the storage amount of the articles;

inquiring a preset food material information base according to the type of the article to obtain unit prices of the article, wherein the food material information base is preset in a refrigerator database or a cloud database, and unit prices corresponding to each article are stored in the food material information base;

The storage amount may be a storage weight or a storage number, and when the storage amount of the article is detected, the storage weight or the storage number of the article is selected and detected according to the type of the article. Specifically, after the type of the article is identified, whether the pricing mode of the article is the re-pricing or the piece-pricing is judged according to the type of the article. For the items with the same price, the storage weight of the items can be obtained through a weight sensor or direct input of a user. For the items which are priced according to the pieces, the storage quantity of the items, namely the number of the items, can be specifically identified through images, or identification codes are arranged on each item, and the storage quantity of the items is judged through the number of the identification codes. In a specific example, for example, when the preserved item is identified to be watermelon, the storage weight of the watermelon is detected, and when the preserved item is identified to be kiwi fruit, the storage quantity of the kiwi fruit is detected.

The price of the item is equal to the product of the unit price of the item and the storage amount. Therefore, the price calculation mode is selected according to the type of the article, and the accuracy is high.

Further, matching a first preservation priority of the item according to the number of deposits includes:

For an item with a large number of storage times, the item is an item that is stored frequently in the refrigerator, and it can be determined that the user's preference for the item is high, and therefore, an item with a large number of storage times, that is, an item with a high number of storage times is matched with a high storage priority weight. Of course, the storage frequency is high when the storage times are large, the consumption rate of the user is high, the storage time of the articles is short, and the preservation requirement of the user is low, so that the low preservation priority weight can be matched with the articles with the large storage times.

Further, matching a second saved priority weight for the item based on the price comprises:

and inquiring a preset food material information base according to the price, and matching a second storage priority weight of the item, wherein the second storage priority weight corresponding to each price is stored in the food material information base.

In particular, a higher second preservation priority weight is matched for items with a higher price, thus the preservation priority weight of the valuable items can be increased.

Third embodiment

A refrigerator food material management method provided by a third embodiment of the present invention is different from the first embodiment in that, in the present embodiment, the refrigerator food material management method matches the storage priority weights of the items according to the accumulated storage durations of the items in a preset time period, referring to fig. 3, and the refrigerator food material management method specifically includes the steps of:

identifying a kind of an article in the refrigerator;

acquiring the single storage time length of the article in a preset time period;

screening the data with the single storage time length smaller than the storage time length threshold;

calculating the accumulated storage time length of the articles, wherein the accumulated storage time length is equal to the sum of data that the single storage time length is less than the storage time length threshold;

and matching the storage priority weight of the item according to the accumulated storage duration.

The single storage duration is the duration from the time when a user puts an article in the refrigerator to the time when the user takes the article out of the refrigerator, the accumulated storage duration is the sum of the single storage durations of the articles when the articles of the same type are put in the refrigerator for multiple times, and in order to improve the accuracy of data, the data of which the single storage duration is greater than the storage duration threshold value are deleted when the accumulated storage duration is calculated. The storage duration threshold is pre-stored in the database, can be a fixed value or a variable value, when the single storage duration of an article is greater than the storage duration threshold, the article is stored in the refrigerator for too long, the article can be determined to be the article which is forgotten to be taken out by a user, and the single storage duration is abnormal data. And a food material information base is preset in the refrigerator or the cloud, and the preset food material information base is inquired according to the accumulated storage time to obtain the storage priority weight.

Whether the articles are frequently stored in the refrigerator can be judged through the accumulated storage time of the articles in the preset time period, and the articles which are frequently stored can be kept fresh with a certain weight. Meanwhile, the data with long storage time of a single time is deleted, so that the situation that the user forgets to take out the stored articles and the storage priority weight is influenced is prevented.

Further, in an embodiment, the method for managing refrigerator food materials further includes:

after the category of the stored article is identified, starting a timer corresponding to the stored article;

after the type of the taken-out article is identified, stopping a timer corresponding to the taken-out article, and recording the single storage time length of the taken-out article, wherein the single storage time length of the article is the time length recorded by the corresponding timer when the article is taken out.

The timer can be a timer independently arranged on the refrigerator and controlled to be turned on or turned off by a user, or a timing module arranged in the refrigerator and automatically triggered after the type of the article is identified.

In another embodiment, after identifying the type of the deposited item, recording the depositing time of the deposited item;

wherein, obtain in the preset time quantum single storage time of article, include:

and acquiring the deposit time of the article and the taking-out time corresponding to each deposit time within a preset time period, and calculating the single-time storage time length which is equal to the difference between the taking-out time and the corresponding deposit time.

Further, in an embodiment, before screening the data with the single storage duration being smaller than the single storage duration threshold, the method further includes:

obtaining the optimal storage time of the article;

and calculating a storage time threshold according to the optimal storage time.

The optimal storage time is the time required for the articles to reach the deterioration critical point under the preset condition, the optimal storage time of different articles is different, and the optimal storage time is also different when the same article is stored under different storage conditions.

The storage duration threshold is determined according to the optimal storage duration for each item. Specifically, the storage time threshold is N times of the optimal storage time, that is, the corresponding storage time threshold is adjusted according to the type of the article, and generally, N is 1 to 1.5. If the optimal storage time of the tomatoes is 5 days, N is preset to be 1.2, the storage time threshold is 6, and when the accumulated storage time is calculated, data with a single storage time longer than 6 days are not counted in the range of the accumulated storage time, so that the situation that a certain object user forgets to take out the data after storage and the accuracy of the priority weight is influenced is avoided.

Further, obtaining the optimal storage time of the article comprises:

and querying a preset food material information base according to the type of the article to acquire the optimal storage time of the article, wherein the optimal storage time corresponding to each article is stored in the food material information base.

Further, in one embodiment, matching the storage priority weight of the item according to the accumulated storage duration comprises:

sorting the articles in the refrigerator according to the accumulated storage time length, and acquiring an accumulated time length ranking corresponding to the articles;

and inquiring a preset food material information base according to the accumulated time length ranking, and matching the storage priority weights of the articles, wherein the food material information base stores the storage priority weight corresponding to each accumulated time length ranking.

The articles with longer accumulated storage time, namely the articles with the accumulated time ranking at the front represent that the articles are frequently stored in the refrigerator, so that the articles are matched with higher storage priority weights. Of course, the items with longer accumulated storage time may be matched with lower storage priority weights according to personal habits or considering other factors.

Fourth embodiment

The refrigerator food material management method provided by the fourth embodiment of the present invention is different from the third embodiment in that, in the present embodiment, the refrigerator food material management method matches the storage priority weights to the articles whose storage times are greater than the preset value according to the accumulated storage time of the articles in the preset time period, that is, the articles whose storage times are less than the preset value are deleted, so as to avoid that the data accuracy is affected by the fact that a certain article is stored only once and the storage time is long. Referring to fig. 4, the refrigerator food material management method includes:

identifying a kind of an article in the refrigerator;

acquiring the accumulated storage time and the storage times of each article in a preset time period;

and matching and storing the priority weight of the articles with the storage times larger than a preset value according to the accumulated storage duration.

sorting the articles with the storage times larger than a preset value according to the accumulated storage time, and acquiring an accumulated time ranking corresponding to each article;

and inquiring a preset food material information base according to the accumulated time length ranking, and matching the storage priority weight of each article, wherein the food material information base stores the storage priority weight corresponding to each accumulated time length ranking.

Fifth embodiment

A refrigerator food material management method according to a fifth embodiment of the present invention is different from the third embodiment in that, in the present embodiment, the refrigerator food material management method matches the storage priority weights of the articles according to the average storage time of the articles in a preset time period, referring to fig. 5, and the refrigerator food material management method specifically includes the steps of:

identifying a kind of an article in the refrigerator;

calculating the average storage time length of the articles, wherein the average storage time length is equal to the ratio of the sum of the data of which the single storage time length is less than the storage time length threshold value to the number of the data of which the single storage time length is less than the storage time length threshold value;

and matching the storage priority weight of the item according to the average storage duration.

The average storage duration is the average storage duration of each time when the same kind of articles are stored in the refrigerator for multiple times by the user. The method for determining the storage duration threshold can be seen in the third embodiment. And a food material information base is preset in the refrigerator or the cloud, and the preset food material information base is inquired according to the average storage duration to obtain the storage priority weight.

Further, matching the storage priority weights of the items according to the average storage duration includes:

sorting the articles in the refrigerator according to the average storage time length, and acquiring an average time length ranking corresponding to the articles;

and querying a preset food material information base according to the average time length ranking, and matching the storage priority weights of the articles, wherein the food material information base stores the storage priority weight corresponding to each average time length ranking.

The average storage time of the articles represents the storage time of the articles in the refrigerator under the general condition, the consumption rate of each article by a user can be obtained by calculating the average storage time, and the articles with longer average storage time represent slower consumption rates of the articles, so that the articles with longer average storage time can be matched with a larger storage priority weight for priority storage. Meanwhile, when the average storage time length is calculated, the data with the single storage time length being greater than the storage time length threshold value is deleted, namely the data with the longer storage time length is deleted, so that the problem that the average storage time length of a certain article is longer and the accuracy of the priority weight storage is influenced because a user forgets to take out the article after putting the article in the storage device can be avoided.

Sixth embodiment

The refrigerator food material management method provided by the sixth embodiment of the present invention is different from the fifth embodiment in that, in the present embodiment, the refrigerator food material management method matches and stores the priority weights to the articles whose storage times are greater than the preset value according to the average storage duration of the articles in the preset time period, that is, the articles whose storage times are less than the preset value are deleted, thereby avoiding the habit data disorder caused by that a certain article is stored only once and the storage time is long. Referring to fig. 6, the refrigerator food material management method includes:

identifying a kind of an article in the refrigerator;

acquiring the average storage time and storage times of each article in a preset time period;

and matching and storing the priority weight of the articles with the storage times larger than the preset value according to the average storage duration.

The average storage duration is calculated, and the average storage duration may include data that the single storage duration is greater than the storage duration threshold, or may not include data that the single storage duration is greater than the storage duration threshold.

The average storage time of the articles represents the storage time of the articles in the refrigerator under the general condition, and the consumption rate of each article by the user can be obtained by calculating the average storage time. The average storage time length of the item represents that the consumption rate of the item is low, so that the item with the longer average storage time length can be matched with the larger storage priority weight for preferential storage. Meanwhile, the articles with less storage times are not counted, and the accuracy of the priority weight storage is improved.
