All other embodiments, which are derived by a person skilled in the art based on the embodiments of the application, fall within the scope of protection of the application.

In order to realize management of the refrigerator on the quality guarantee period of food materials and improve user experience, the application provides an intelligent refrigerator, quality guarantee period determining method, equipment and medium.

Fig. 1 is a schematic structural diagram of an intelligent refrigerator 100 according to some embodiments of the present application, where the intelligent refrigerator 100 includes:

an acquisition unit 101, wherein the acquisition unit 101 is used for acquiring information of the stored food materials;

a controller 102, the controller 102 configured to perform:

In the application, when food materials are stored, the intelligent refrigerator can determine the names of the food materials and the stored positions of the food materials, and particularly, the acquisition unit of the intelligent refrigerator is used for acquiring information of the stored food materials, wherein the acquisition unit can be image acquisition equipment and is used for acquiring images containing the food materials, and the images carry the information of the stored food materials. The controller of the intelligent refrigerator responds to the collected information of the stored food materials, and determines the names and storage positions of the food materials, wherein the storage positions are specific positions of the food materials in the intelligent refrigerator, such as the left side of the second layer. In addition, in the application, the image acquisition device is arranged at a preset position in the intelligent refrigerator, and the preset position ensures that when the image acquisition device is arranged at the preset position, images of all positions of food materials can be stored in the intelligent refrigerator.

After the food is stored, the image acquisition device in the intelligent refrigerator acquires an image containing the stored food, and after the image is obtained, the stored food contained in the image is identified based on an image identification technology, and the name and the storage position of the stored food are determined, wherein the process of identifying the name and the storage position of the food through the image identification technology belongs to the prior art and is not repeated herein.

Since the image acquired by the image acquisition device including the stored food material may have an unclear condition, it may be caused that the name of the stored food material cannot be recognized based on the image recognition technology. Therefore, in order to ensure that the names of the stored food are obtained, in the embodiment of the present application, if the names of the stored food are not recognized based on the image recognition technology, the intelligent refrigerator outputs the inquiry information of the names of the food, where the inquiry information may be "please ask what is the names of the food you just stored". After the user answers according to the inquiry information, that is, after the intelligent refrigerator receives the reply information, the reply information can be text information or voice information. Interaction is typically performed by voice. When the intelligent refrigerator receives the reply information, the key words contained in the reply information are identified based on a voice recognition technology, and the names of the stored food materials are determined, wherein the names of the stored food materials are determined to be the prior art through the voice recognition technology, and details are omitted.

In the application, since the food material is stored after being taken out when being stored in the intelligent refrigerator, that is, the intelligent refrigerator has the food material with the same name as the food material, the stored food material can also be the food material which is just purchased and stored, that is, the intelligent refrigerator has no food material with the same name as the food material. And when the food material is stored, if the intelligent refrigerator has the food material with the same name as the food material, the food material may be stored at the position where the food material with the same name as the food material is located or may be stored at other positions when being stored, so that according to the different situations, the method for determining the quality guarantee period is different according to the different situations.

In the application, the shelf life of the food is determined according to whether the food with the name is stored in the position and whether the food with the name is taken out within the preset time length.

In order to determine the shelf life of the food material, on the basis of the above embodiments, in the present application, the controller 102 is configured to perform:

outputting inquiry information of whether the food material is the taken food material or not if the food material with the name is taken out in the preset time length according to the recorded information of the taken food material in the preset time length; determining the quality guarantee period of the food material according to the acquired reply information; and if the fact that the food materials with the names are not taken out within the preset time length is determined, determining the quality guarantee period of the food materials according to the relation between the pre-stored food material names and the quality guarantee period.

In the present application, the food material of the name may be taken out within the preset time period or not taken out within the preset time period, if the food material of the name is taken out within the preset time period, it is indicated that the stored food material may be taken out and then stored, and if the food material of the name is not taken out within the preset time period, it is indicated that the stored food material is the first stored food material within the preset time period. Therefore, in order to determine whether the stored food is the food that is taken out within the preset time period, it may be determined whether the food of the name is taken out within the preset time period based on the history of the food, that is, according to the recorded information of the food that is taken out within the preset time period, wherein the preset time period is set according to the requirement.

If it is determined that the food material with the name is taken out within the preset time length, the food material is likely to be taken out and then stored, and in order to determine whether the food material is taken out and then stored, and further determine the shelf life of the food material, query information of whether the food material is taken out is output, reply information is received, and the shelf life of the food material is determined according to the reply information. If it is determined that the food material with the name is not taken out within the preset time length, the food material is indicated to be the food material stored for the first time within the preset time length.

In order to accurately determine the shelf life of the food materials, the controller 102 is configured to perform:

if the food with the name is stored in the position, according to the acquired reply information, if the food is determined to be the food taken out within a set time length, taking the quality guarantee period of the food with the name stored in the position as the quality guarantee period of the food; and if the food material is determined to be taken out within the non-set time length, determining the shelf life of the food material according to the pre-stored relationship between the name and the shelf life of the food material.

In the application, the shelf life of the food is determined according to whether the food with the name and the reply information are stored in the stored position of the food. Specifically, since the stored food may or may not have the same name as the stored food at the position of the intelligent refrigerator, there may be different ways of determining the shelf life.

If the stored food material has the same name as the stored food material at the position, identifying the keyword in the reply information according to the reply information, and determining that the stored food material is the food material taken out within the set time length, that is, determining that the stored food material may be the food material taken out and put into the refrigerator, the shelf life of the stored food material is the same as the shelf life of the food material with the same name at the position, that is, the stored food material is the food material taken out from the position within the preset time length. If the key word of the reply message is identified according to the reply message, and the food material taken out in the non-set time length of the food material is determined, namely, the food material is determined to be the food material stored for the first time in the preset time length, the quality guarantee period of the food material is determined according to the relation between the name of the pre-stored food material and the quality guarantee period.

For ease of management, based on the above embodiments, in the present application, the controller 102 is configured to perform:

and outputting prompt information for storing the food materials at other positions if the food materials with the names are stored at the positions and the food materials with the names are not taken out within the preset time length.

In the present application, if the food material with the name is stored in the position, and if it is determined that the food material with the name is not taken out within the preset time period, it is indicated that the stored food material is the first stored food material within the preset time period, and since the food material with the same name as the food material exists in the position where the food material is stored, and the shelf life of the food material is different from the shelf life of the food material with the same name as the food material, for convenience of management, the prompt information for storing the food material in other positions is output.

if the food material with the same name as the food material is not stored at the position, according to the acquired reply information, if the food material is determined to be the food material which is taken out within the set time length, taking the quality guarantee period of the food material with the same name as the food material as the quality guarantee period of the food material; and if the food materials which are taken out in the non-set time length are determined, determining the shelf life of the food materials according to the relation between the name of the pre-stored food materials and the shelf life.

In the application, when the food material is stored in the intelligent refrigerator, if the food material with the same name as the food material does not exist at the position of the stored food material, the keyword contained in the reply information is identified, whether the stored food material is the taken-out food material within the preset time length is judged, if yes, the food material is taken out and then stored, and the quality guarantee period of the food material with the same name as the food material is taken as the quality guarantee period of the food material. If the stored food is not the taken food within the preset time length, that is, the food is the first stored food within the preset time length, in order to determine the shelf life of the stored food, the shelf life of the food is determined according to the relationship between the name of the pre-stored food and the shelf life. For example, the set time period may be 1 day or the like.

and outputting prompt information for storing the food materials at the positions of the food materials with the same names as the food materials when the food materials with the same names as the food materials are not stored at the positions and the food materials with the same names as the food materials are taken out within the preset time length.

In the present application, if the food material having the same name as the food material is not stored at the position, and it is determined that the food material having the same name as the food material is taken out within the predetermined time period, the stored food material is a food material that is taken out and then stored, and the stored position of the food material is different from the stored position of the food material having the same name as the food material, so that the present application outputs the presentation information for storing the food material at the position of the food material having the same name as the food material for convenience of management.

Fig. 2 is a method for determining whether a food material having the same name as a stored food material is taken out within a predetermined time period according to some embodiments of the present application, and the description of fig. 2 is now provided.

The time length t, that is, the preset time length is predefined. After the food material is manually put into the intelligent refrigerator, that is, after the food material is stored into the intelligent refrigerator, judging whether the food material is the same as the name of the food material taken out in the preset time length, that is, determining whether the stored food material is the food material taken out in the preset time length, if not, indicating that the food material is the food material taken out in the non-preset time length, that is, the food material is the food material stored for the first time in the preset time length, so that the name, the position information and the quality guarantee period information of the stored food material are determined.

If the food material taken out in the preset time length contains the food material with the same name as the stored food material, the stored food material may be the food material taken out in the preset time length or the food material taken out in the non-preset time length, the intelligent refrigerator inquires whether the food material is the food material taken out in the preset time length or not through voice, wherein the preset time length is set according to requirements, the intelligent refrigerator determines that the food material is the food material taken out in the preset time length according to the reply information of the voice inquiry, and then the shelf life history of the stored food material is determined according to the food material access record of the intelligent refrigerator, and the shelf life of the stored food material is determined according to the shelf life history of the stored food material. Since the position information of the stored food material can be determined based on the image recognition technology, after the name, the position information, and the shelf life of the stored food material are obtained, the information corresponding to the food material in the database is updated.

In order to distinguish the shelf life of the fresh-cut food material and the non-fresh-cut food material corresponding to the same name, the controller 102 is configured to perform:

If the food material is determined to be fresh-cut food material, determining the quality guarantee period of the food material according to the relationship between the fresh-cut food material and the quality guarantee period of the name in the relationship between the name of the pre-stored food material and the quality guarantee period;

and if the non-fresh-cut food material of the food material is determined, determining the shelf life of the food material according to the relationship between the non-fresh-cut food material of the name and the shelf life in the pre-stored relationship between the name and the shelf life of the food material.

Since some food materials can be divided into fresh-cut food materials and non-fresh-cut food materials, and the shelf life of the fresh-cut food materials and the shelf life of the non-fresh-cut food materials corresponding to the food materials with the same name are different, in the pre-stored relationship between the name of the food material and the shelf life, the relationship between the fresh-cut food materials corresponding to the name of the same food material and the shelf life and the corresponding relationship between the non-fresh-cut food materials and the shelf life are stored, and in general, the shelf life of the fresh-cut food materials is smaller than the shelf life of the non-fresh-cut food materials. For example, in relation to a food material with a food material name of tomato, in the relation between the name of the food material and the shelf life stored in advance, the relation between the fresh-cut tomato and the shelf life and the relation between the non-fresh-cut tomato and the shelf life are stored. After the food material is stored, after the name of the food material is determined, it is necessary to determine whether the food material is a fresh cut food material or a non-fresh cut food material before determining the shelf life of the food material.

In order to determine the shelf life of the food, if the food is determined to be a fresh-cut food, the shelf life of the food is determined based on the relationship between the fresh-cut food and the shelf life of the name of the pre-stored food, and if the non-fresh-cut food is determined, the shelf life of the food is determined based on the relationship between the non-fresh-cut food and the shelf life of the name of the pre-stored food.

Fig. 3 is a method for determining a shelf life based on fresh-cut food and non-fresh-cut food according to some embodiments of the present application, and the method will now be described with reference to fig. 3.

If the food material is manually put in, the intelligent refrigerator can acquire food material information, that is to say, the name and the position information of the stored food material can be identified based on an image identification technology, whether the food material is a fresh-cut food material is judged, specifically, whether the food material is a fresh-cut food material can be determined based on the image identification technology, if yes, the quality guarantee period of the fresh-cut food material is determined according to the corresponding relation between the name of the pre-stored food material and the quality guarantee period of the fresh-cut food material corresponding to the name of the food material in the corresponding relation between the name of the stored food material and the quality guarantee period, and the position information of the stored fresh-cut food material is determined based on the image identification technology. In order to facilitate distinguishing and management, newly-built fresh-cut food material records are stored in a partition mode, if the food material is a non-fresh-cut food material, the quality guarantee period of the non-fresh-cut food material is determined according to the corresponding relation between the non-fresh-cut food material corresponding to the name of the food material and the quality guarantee period in the corresponding relation between the name of the pre-stored food material and the quality guarantee period, the stored position information of the non-fresh-cut food material is determined based on an image recognition technology, and the data information of the non-fresh-cut food material in a database is updated.

If the stored food is not the fresh-cut food or the non-fresh-cut food based on the image recognition technology, the information of the food can be input through voice interaction, namely the intelligent refrigerator can perform voice interaction with a user, the intelligent refrigerator outputs query information about whether the fresh-cut food is or not, for example, the intelligent refrigerator outputs query information about whether the fresh-cut tomatoes are put in, the intelligent refrigerator determines whether the food is the fresh-cut food according to the reply information, if the received reply information is a positive answer, namely, the food is determined to be the fresh-cut food according to the reply information, the shelf life of the fresh-cut food is determined according to the corresponding relation between the name of the pre-stored food and the shelf life of the fresh-cut food, and the data information of the fresh-cut food is stored in the fresh-cut food record, and the data information of the non-fresh-cut food is stored in a partition mode; if the received reply information is a negative answer, that is, the food material is determined to be non-fresh-cut food material according to the reply information, the quality guarantee period of the non-fresh-cut food material is determined according to the corresponding relation between the non-fresh-cut food material corresponding to the name of the food material in the corresponding relation between the name of the pre-stored food material and the quality guarantee period, the stored position information of the non-fresh-cut food material is determined based on an image recognition technology, and the data information of the non-fresh-cut food material in a database is updated.

In order to query the shelf life of the food, based on the above embodiments, in the present application, the controller 102 is configured to perform:

if an overdue food material inquiry command is received, determining the remaining duration of the quality guarantee period according to the stored time of the food material and the determined quality guarantee period;

outputting prompt information that the food material is out of date if the remaining period of the quality guarantee period of the food material is smaller than a preset first period threshold;

if the remaining time length of the food material is larger than a preset first time length threshold value and is not larger than a preset second time length threshold value, outputting prompt information that the food material is about to expire, wherein the second time length threshold value is larger than the first time length threshold value.

In the application, when a request for inquiring the expired food material exists, that is to say, after receiving an inquiry instruction of the expired food material, determining the remaining duration of the shelf life according to the stored time of the food material and the determined shelf life, presetting a prompt requirement, and outputting prompt information about the shelf life if the remaining duration of the shelf life meets the preset prompt requirement. In order to facilitate the determination of the names and specific positions of the expired food, the prompt information carries the names of the food and the position information stored in the refrigerator.

Specifically, in the process of determining whether the remaining duration of the shelf life meets the preset prompting requirement and further outputting prompting information about the shelf life, the stored food material may be out of date, and the condition about to be out of date may also occur, so that in order to accurately determine whether the food material is out of date, the prompting information about the shelf life is accurately output. Specifically, if the remaining duration of the shelf life of the food is less than a preset first time threshold, the food is indicated to be expired, so that prompt information that the food is expired is output, wherein the first time threshold may be 0 days.

If the remaining period of the food material is longer than the preset first period threshold and is not longer than the preset second period threshold, the food material is not expired, but is about to be expired, so that prompt information about the food material about to be expired is output, wherein the second period threshold is greater than the first period threshold. When the first time threshold is 0 days, the second time threshold may be 1 day or 2 days. In addition, if the second time threshold is 2 days, in order to accurately determine a specific time period for which the food material is about to expire, in the present application, a third time threshold may be preset, where the third time threshold is smaller than the second time threshold and larger than the first time threshold, and the third time threshold may be 1 day, if the remaining time period of the food material is longer than the preset third time threshold and not larger than the preset second time threshold, it indicates that the food material will expire in the next day, so as to output a prompt message that the food material will expire in the next day, and if the remaining time period of the food material is not longer than the preset third time threshold but larger than the preset first time threshold, it indicates that the food material will expire in the next day, so as to output a prompt message that the food material will expire in the next day.

For example, an apple placed in the middle position of the first layer of the intelligent refrigerator exists in the intelligent refrigerator, the apple is stored for 2 months and 2 days, the quality guarantee period of the apple is determined to be 15 days based on the relation between the name of the pre-stored food material and the quality guarantee period, the time for receiving the expiration food material inquiry command is 2 months and 16 days, the remaining time of the quality guarantee period is determined to be 1 day, if the first time threshold is 0 day, the second time threshold is 1 day, and because the remaining time of the quality guarantee period of the food material is not greater than the preset first time threshold but not greater than the preset second time threshold, prompt information about the impending expiration of the food material is output.

In the present application, the information on the expiration date may be output based on a display screen, or may be output based on sound, and if the information is output based on the display screen, text of the information on the expiration date is displayed on the display screen when the information on the expiration date is output, and if the information on the expiration date is output based on sound, voice of the information on the expiration date is played when the information on the expiration date is output.

In addition, in order to remind a user of whether food stored in the refrigerator is about to expire or has expired in time, the method can be preset when a refrigerator door of the intelligent refrigerator is opened, namely, when the intelligent refrigerator receives the expired food inquiry command, prompt information about the shelf life is output.

In order to accurately determine the remaining duration of the shelf life of the food materials, the controller 102 is configured to perform:

if a food material shelf life remaining time length inquiry command is received, determining a target food material to be inquired according to the food material shelf life remaining time length inquiry command, and outputting the shelf life remaining time length of the target food material.

In the application, if the demand for inquiring the food material quality guarantee period residual duration exists, a food material quality guarantee period residual duration inquiry command can be sent to the intelligent refrigerator, wherein the food material quality guarantee period residual duration inquiry command carries information of a target food material of which the food material quality guarantee period residual duration is to be inquired, so that after the intelligent refrigerator receives the food material quality guarantee period residual duration inquiry command, the target food material to be inquired is determined, and the quality guarantee period residual duration of the target food material is determined and output. When outputting the remaining duration of the shelf life, the remaining duration of the shelf life of the target food material can be subjected to voice broadcasting, for example, broadcasting by an intelligent refrigerator: the remaining shelf life duration of the tomatoes in the first layer middle position in the refrigerator is 4 days, and the output can be performed in a text mode, for example, the text of the remaining shelf life duration of the tomatoes in the first layer middle position in the refrigerator is 4 days is displayed on a display screen of the intelligent refrigerator.

In addition, in the application, the deposit time of the food materials to be deposited in the intelligent refrigerator can be inquired, and in particular, the intelligent refrigerator receives a food material deposit time inquiry command, wherein the food material deposit time inquiry command carries information of a target food material of which the deposit time is to be inquired, so that the intelligent refrigerator determines the target food material to be inquired according to the food material deposit time inquiry command, determines the deposit time of the target food material and outputs the target food material.

In order to modify the food material shelf life duration, on the basis of the above embodiments, in the present application, the controller 102 is configured to perform:
