[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0030] In order to solve the problem that the food information displayed on the refrigerator display screen in the related art is manually recorded by the user, and the recording process is cumbersome and complicated, resulting in a poor user experience, the present application provides a method for displaying attribute information of food in a refrigerator, such as Figure 1 As shown, the steps of the method include:

[0031] Step 101, obtaining the area and time of food being put into the refrigerator, wherein the refrigerator is divided into multiple areas, and a corresponding sensor is set in each area;

[0032] In a specific example, the refrigerator can be divided into a double-sided door of the refrigerator as a bracket area, the internal space of the refrigerator can be provided with a tray to separate it into several areas, and a cabinet area can also be provided. Each area for placing food is provided with a corresponding sensor, such as a pressure sensor. Among them, the number of sensors can be set according to actual needs, and in the embodiment of the present application, if multiple foods are placed in the area sensed by the same sensor, the sensor can simultaneously sense the weight of the multiple foods, that is, the graphic data of the pressure part of the multiple foods.

[0033] Step 102, obtaining the weight of the food and the graphic data of the pressure part based on the sensor set in the area;

[0034] In a specific example, if the current food needs to be served in a bowl or a plate, the weight of the food obtained by the sensor refers to the weight including the bowl or plate. If the current food is an assembled beverage or other food that can be directly placed in the refrigerator, the weight of the food obtained by the sensor is the weight including the food packaging. For the graphic data of the pressure part, if the food is currently placed in the refrigerator in a bowl, the corresponding pressure part is the part where the bottom of the bowl contacts the refrigerator. If the bottom of the bowl is a circular support ring, the graphic data is a circular graphic data. If the bottom of the bowl is a square support ring, the graphic data is a square graphic data. For other foods that do not require bowls or plates, such as bottled beverages, the graphic data corresponding to the pressure part is the graphic data formed by the contact between the bottom of the bottle and the refrigerator.

[0035] Step 103, determining the category of the food based on the weight and the graphic data, and determining the pre-storage time of the food based on the category;

[0036] In this regard, in a specific example, for packaged food, the corresponding category can be determined directly through the graphic data of the pressure part and the weight. For example, mineral water has a certain packaging box and weight. After being placed in the refrigerator, the corresponding packaging can be determined according to the bottom graphic data, and then the category of the food can be determined as mineral water according to the weight. For foods that need to be contained in bowls, plates or other containers, the type of container can also be identified according to the graphic data to infer the category of the food contained in the current container. Because, usually, the shapes of containers for different purposes are different, such as casseroles for soup, plates for serving dishes, and bowls for eating. The corresponding food category can be determined according to their different uses. If the current identification is a casserole according to the graphic data, the casserole should contain soup. Usually, the storage time of the prepared soup should not exceed two or three days. Or, the current identification is a plate for serving Cai according to the graphic data. According to the weight, it can be further determined whether it is a meat dish or a vegetarian dish. Usually, meat dishes will be heavier, and vegetarian dishes will be lighter. The storage time of meat dishes is slightly longer, about three days, and the storage time of vegetarian dishes is about one day.

[0037] Step 104, displaying at least one of the following attribute information of the food on the display screen of the refrigerator: time of placement, pre-storage time, category and quantity.

[0038] Through the above steps 101 to 104, in the embodiment of the present application, after the food is placed in the refrigerator, the time of placing the food is recorded first, and then the weight of the food and the graphic data of the pressure part are obtained through the sensor, and then the category of the food is determined according to the weight and the graphic data. After the category is determined, the pre-storage time of the food can be determined according to the category, and the time of placing the food, the pre-storage time, the category and the quantity are displayed on the display screen of the refrigerator. It can be seen that through the method of the embodiment of the present application, the user does not need to manually record the attribute information of the food, but the refrigerator can automatically align for statistics and display the statistical results on the display screen. Through the method of the embodiment of the present application, the statistics of food attribute information are more comprehensive, and the user's experience of using the refrigerator is also improved, which solves the problem that the food information displayed on the refrigerator display screen in the related art is manually recorded by the user, and the recording process is cumbersome and complicated, resulting in a poor user experience.

[0039] In the embodiment of the present application, the attribute information of the corresponding food can be identified according to the graphic data. For example, if the current image data is a circle, the food is a food in a bowl. If the current graphic data is a rectangle, the food is a beverage or milk in a paper bag. Based on this, the method of determining the category of the food based on the weight and graphic data involved in step 103 of the embodiment of the present application can further include:

[0040] Step 11, determining attribute information of the pressure portion according to the graphic data, wherein the attribute information represents the object containing the food;

[0041] Step 12, matching the attribute information and weight with preset storage information to determine the category of the food, wherein the storage information includes a mapping relationship, which is a mapping relationship between the attribute information, weight and category.

[0042] In this regard, in a specific example, the item for holding food can be a container for holding food, or it can be the packaging of the food itself, or it can be an object stored in the refrigerator, such as an egg box for placing eggs. For food with standard food packaging, after obtaining the corresponding weight and graphic data, the category of the current food can be determined by matching according to the pre-stored weight and image data. For example, the corresponding weight and graphic data of 500ml of mineral water will not change under normal circumstances, so only the weight and graphic data need to be obtained to determine that it is 500ml of mineral water. For food that requires a container to hold, the category of the food is determined according to the type of container. Usually different containers have different functions, such as bowls for eating, plates for serving dishes, and pots for making soup, and the shapes of these containers are also different. The graphic data of the pressure part can distinguish different types of containers, and then the type of food held by the current container can be determined, such as rice, leftovers, soup, etc. Therefore, before identifying the food category, it is necessary to store the graphic data of the bottom of each container, the graphic data of the bottom of each standard package or non-standard package, and the graphic data of the bottom of the built-in refrigerator for storing special foods.

[0043] In the embodiment of the present application, the method of matching the attribute information and weight with the preset storage information involved in the above step 12 to determine the category of the food may further include:

[0044] Step 21, when the attribute information indicates that the item for holding food is a container, determine the type of the container, and match the type with the stored information to determine the category of the food;

[0045] Step 22, when the attribute information indicates that the article containing the food is a food packaging, the weight of the packaging and the food is matched with the preset storage information to determine the category of the food;

[0046] Step 23, when the attribute information indicates that the item containing food is a built-in storage item of the refrigerator, the storage item is matched with the preset storage information to determine the category of the food.

[0047] It can be seen that in the embodiment of the present application, different utensils play different roles. Therefore, by identifying the graphic data at the bottom of the vessel, the specific category of the vessel can be determined, and then the approximate category of the food in the current vessel can be determined. For example, if the identified dish is a plate of food, the food in the plate can be a cooked dish, a meat dish or a vegetarian dish, but no matter which one, the pre-storage time of the cooked dish in the refrigerator will not be very long, generally two or three days, three or four days. If the result of the identification is a standard package, the specific food can be determined by the weight and the graphic data at the bottom of the package, such as assembled beverages, bagged milk, etc. These standard packages usually have a standard shelf life, but in the embodiment of the present application, it is usually recommended that users consume them within half a month, that is, consume these standard packaged foods within the best time. In the embodiment of the present application, there is also a special food, such as eggs, which can be placed in a storage item specifically used for placing eggs in the refrigerator. Through the weight and graphic data, it can be known how many eggs are currently placed in the refrigerator, and the corresponding pre-storage time is set for each egg.

[0048] In the embodiment of the present application, for standard packaged food, the user may not eat it all at once, but may eat it in multiple times, so the pre-storage time of the food also needs to be updated in time. Based on this, after determining the pre-storage time of the food based on the category, such as Figure 2 As shown, the method of the embodiment of the present application may also include:

[0049] Step 201, when the attribute information indicates that the article containing food is a food packaging, after determining that the weight of the food decreases within a preset time, shorten the current pre-storage time of the food according to the reduced weight.

[0050] In this regard, in a specific example, if the current food is a standard packaged food, specifically 500ml bottled water, the initial pre-storage time is 15 days. On the third day, that is, when there are 12 days left in the pre-storage time, after the user consumes 200ml of it, it is necessary to adjust the pre-storage time of the bottled water in time. Specifically, the pre-storage time can be shortened according to the ratio of the weight of the used water to the initial water, that is, the current ratio is 200 / 500=0.2, so the shortened pre-storage time is 12-12*0.2=9.6. Furthermore, the pre-storage time can be set from 12 days to 10 days by rounding off. In this way, not only can the pre-storage time be adjusted in a timely and accurate manner, but the user can also be reminded in time to process the consumed food as soon as possible.

[0051] In the embodiment of the present application, for the food contained in the container, the food may be added or reduced in the subsequent process, so the corresponding pre-storage time also needs to be shortened accordingly so that the user can eat the food within the safe period. Based on this, after determining the pre-storage time of the food based on the category, such as Figure 3 As shown, the method of the embodiment of the present application includes:

[0052] Step 301, when the attribute information indicates that the item for holding food is a container, after determining that the weight of the food has increased, shortening the pre-storage time of the current food based on a preset first ratio;

[0053] Step 302, when the attribute information indicates that the item for holding food is a container, after determining that the weight of the food has decreased, shorten the pre-storage time of the current food based on a preset second ratio; wherein the first ratio is smaller than the second ratio.

[0054] For the above steps 301 and 302, in a specific example, for example, the current vessel is a casserole, and the food in the casserole is pork rib soup. After the casserole containing the pork rib soup is placed in the refrigerator for the first time, the corresponding food category is determined according to the graphic data of the casserole, and the corresponding pre-storage time is determined. For example, the pre-storage time under the current weight is 3 days, and then the same pork rib soup is added to the current casserole, which increases to 1.5 times the original. The corresponding first ratio is 1 / 3, and the corresponding pre-storage time after adding the pork rib soup in the casserole is 3-3*1 / 3=2 days. If the pork rib soup in the current casserole has been consumed by half, the corresponding first ratio is 2 / 3, because the corresponding pre-storage time after a part of the pork rib soup in the casserole is consumed is 3-3*2 / 3=1 day. It should be noted that the above first ratio and second ratio have no direct relationship with the increase or decrease in weight, and are both preset. However, when different vessels contain different foods, the corresponding proportional relationship is different. By adjusting the pre-storage time of food in real time during the process of adding or reducing food, users can be reminded to eat the corresponding food in time.

[0055] In an optional implementation manner of the embodiment of the present application, after the display screen of the refrigerator displays the food attribute information, such as Figure 4 As shown, the method of the embodiment of the present application may also include:

[0056] Step 401, when the difference between the pre-stored time of the food and the pre-stored time is less than a preset threshold, and the sensor determines that the food has left the refrigerator, play a voice prompt message, wherein the voice prompt message is used to remind the user of the storage time of the food.

[0057] In this regard, in a specific example, if the current food is pre-stored for 10 days and has been pre-stored for 7 days, when the user eats it, the user can be reminded in time that the current food pre-stored time is about to expire and should eat it in time. That is, the user is reminded when eating the food, so that the user can eat it in time.

[0058] In an optional implementation manner of the embodiment of the present application, the method of the embodiment of the present application may further include:

[0059] Step 31, when multiple foods of the same category are identified, the pre-stored durations of the multiple foods of the same category are displayed on the display screen according to the positions of the multiple foods.

[0060] It can be seen that in the embodiment of the present application, the pre-storage durations of multiple foods of the same category can be displayed respectively, because the same category of foods may be placed in the refrigerator at different times, and therefore, the corresponding current pre-storage durations are different. By displaying the corresponding pre-storage durations in different positions, these foods of the same category can be further distinguished and selected.

[0061] The present application is explained below in conjunction with the optional implementation of the embodiment of the present application. This specific implementation provides a method for a refrigerator to automatically identify the storage time of food. The structure of the refrigerator in this specific implementation is as follows: Figure 5 As shown, based on this, the method in the specific implementation mode is as follows: Figure 6 As shown, the following steps are included:

[0062] Step 601, triggered when the refrigeration equipment door is opened or closed;

[0063] Step 602, when the food is placed in the refrigeration device, the storage location and placement date of the food are obtained;

[0064] Step 603, automatically classify the food according to the food storage location, the pressure sensing image and the database after pairing, and bind the storage time;

[0065] Step 604, the display screen displays the video classification and related information, and the user can confirm or modify the information;

[0066] Step 605, determining the best shelf life of the food;

[0067] Step 606, issuing a reminder based on the food approaching the temporary or optimal use time.

[0068] From the above steps 601 to 606, it can be seen that the user opens Figure 7When the refrigerator door is opened, the refrigerator main control system starts recording time and detecting all pressure sensors (trays, brackets, etc.); when the user puts food into the refrigerator space with pressure sensors (trays, brackets, etc.), the food storage location and the time and date of placement are recorded and bound. Preliminary screening can be distinguished according to the food storage location, such as the door bracket and the cabinet tray; the pressure sensor can obtain the pressure distribution information and weight of the bottom of the food. Through the matching and calculation of a large amount of data in the database, the graphic data and weight of the pressure distribution can be used to associate and filter out the food category. For example, the bowl and dish category is more cooked food, and the standard categories are cola and milk. The weight and number of eggs placed in the egg rack can be distinguished. In this specific implementation method, the pressure sensor can automatically plan the amount of food data to be stored, and can also evaluate and calculate the historical data (graphics and weight) and time to measure whether the item has been recorded before. The location, deletion, and re-storage operations can be automatically modified. For example, if a bowl of soup is taken out of the refrigerator and then immediately taken back and put back, the shelf life and category will be automatically recorded;

[0069] In addition, all calculated results of stored food will be displayed to the user through the display screen (or voice or APP), and the food category, quantity, weight, storage date, and best storage date will be displayed in the order of storage. The user can confirm the results. If there are any questions, all the above information can be modified directly. The verification operation will save the latest food information content and will affect the database content, making the data closer to user use. After the food is successfully stored, the shelf life timing service is always started to determine whether the food has passed the best shelf life. When it expires, it will be sent to the display device. When the refrigerator determines that the storage time of the food exceeds the best shelf life (approaching the temporary period), it will send a reminder message and the display interface prompts (or voice broadcast, APP push).

[0070] Corresponding to the above Figure 1 The present application also provides a device for displaying attribute information of food in a refrigerator, such as Figure 8 As shown, the device comprises:

[0071] The first acquisition module 802 is used to acquire the area and time when the food is put into the refrigerator, wherein the refrigerator is divided into multiple areas, and a corresponding sensor is set in each area;

[0072] A second acquisition module 804 is used to acquire the weight of the food and the graphic data of the pressure part based on the sensor set in the area;

[0073] A first processing module 806, for determining the category of the food based on the weight and the graphic data, and determining the pre-storage time of the food based on the category;

[0074] The display module 808 is used to display at least one of the following attribute information of the food on the display screen of the refrigerator: the time of placement, the pre-storage time, the category and the quantity.

[0075] Through the device of the embodiment of the present application, after the food is placed in the refrigerator, the time of placing the food is recorded first, and then the weight of the food and the graphic data of the pressure part are obtained through the sensor, and then the category of the food is determined according to the weight and graphic data. After the category is determined, the pre-storage time of the food can be determined according to the category, and the time of placing the food, pre-storage time, category and quantity are displayed on the display screen of the refrigerator. It can be seen that through the method of the embodiment of the present application, there is no need for the user to manually record the attribute information of the food, but the refrigerator can automatically align for statistics and display the statistical results on the display screen. Through the method of the embodiment of the present application, the statistics of food attribute information are more comprehensive, and the user's experience of using the refrigerator is also improved, solving the problem that the food information displayed on the refrigerator display screen in the related art is manually recorded by the user, and the recording process is cumbersome and complicated, resulting in a poor user experience.
