Some embodiments of the present disclosure provide a refrigerator 100. As shown in fig. 1, the refrigerator 100 includes a label detecting device 30, a door opening and closing detecting device 40, a controller 50, a compressor 61, a condenser 62, and an evaporator 63. The controller 50 is coupled with the first tag detecting device 30, the door opening and closing detecting device 40, the compressor 61, the condenser 62, and the evaporator 63, and the first tag detecting device 30, the door opening and closing detecting device 40, the compressor 61, the condenser 62, and the evaporator 63 operate under the control of the controller 50.
The following mainly exemplifies the cooling operation principle of the refrigerator 100.
The cooling process of the refrigerator 100 includes a compression process, a condensation process, a throttle process, and an evaporation process. The compression process comprises the following steps: the compressor 61 sucks a low-temperature, low-pressure refrigerant, compresses the refrigerant into a high-temperature, high-pressure superheated gas, and drives the superheated gas into the condenser 62. The condensation process is as follows: the condenser 62 cools the high-temperature and high-pressure refrigerant gas into normal-temperature and high-pressure saturated vapor, and then further cools the saturated vapor to obtain a saturated liquid of the refrigerant. The throttling process is as follows: the saturated liquid of the refrigerant flows into the capillary after moisture and impurities are removed by the dry filter, and the capillary is throttled and depressurized, and then the saturated liquid is converted into wet vapor at normal temperature and low pressure, and the wet vapor enters the evaporator 63. The evaporation process is as follows: the evaporator 63 evaporates the normal-temperature low-pressure wet vapor into low-temperature low-pressure dry saturated vapor, thereby absorbing heat around the evaporator 63 and reducing the temperature inside the refrigerator 100. The evaporator 63 may further input the vaporized refrigerant into the compressor 61 again to recycle the refrigerant.
Hereinafter, a process of food management by the refrigerator 100 using an electronic tag will be exemplarily described with reference to the accompanying drawings.
As shown in fig. 2, some embodiments of the present disclosure provide a refrigerator 100 including a cabinet 10 and a door 20. The door 20 is provided on the case 10.
The tag detection apparatus 30 is configured to detect an electronic tag in a refrigerator. The electronic tag is configured to store information related to the food material. The door opening and closing detecting means 40 is configured to detect opening and closing of the door 20.
The controller 50 is coupled with the tag detection apparatus 30 and the door switch detection apparatus 40, and is configured to:
Acquiring information of all electronic tags in the refrigerator 100 through the tag detection apparatus 30 in response to a door closing signal from the door opening and closing detection apparatus 40 to obtain a first tag information set;
comparing the first set of tag information with the second set of tag information; the second tag information set is information of all electronic tags in the refrigerator 100 acquired through the tag detection apparatus 30 in response to the last door closing signal of the above door closing signal;
if the second tag information set comprises a first electronic tag which does not exist in the first tag information set, updating the taking-out time of the first food material related to the first electronic tag according to the receiving time of the door closing signal;
If the first tag information set includes a second electronic tag which does not exist in the second tag information set, updating the time of putting the second food material associated with the second electronic tag according to the time of receiving the door closing signal, and updating the shelf life of the second food material according to the time of putting the second food material.
When a user uses the refrigerator, a situation that food materials in the refrigerator are taken out and then put back into the refrigerator may occur, and after the food materials are taken out from the refrigerator, the storage temperature of the food materials generally increases, thereby causing the shelf life of the food materials to be shortened. The refrigerator 100 provided in some embodiments of the present disclosure can obtain the first tag information set by using the tag detection apparatus 30 to obtain information of all electronic tags in the refrigerator 100 when the door switch detection apparatus 40 detects that the door 20 is closed. And then comparing the first tag information set with a second tag information set obtained when the refrigerator door 20 is closed last time, and if the first tag information set includes a second electronic tag which does not exist in the second tag information set, indicating that the second electronic tag is a new tag which is put into the refrigerator 100 by the user before the refrigerator is closed this time. At this time, the time of putting in the second food material associated with the second electronic tag may be updated according to the time of receiving the door closing signal from the door opening/closing detecting device 40, and the shelf life of the second food material may be updated according to the time of putting in the second food material. Therefore, the refrigerator 100 provided in some embodiments of the present disclosure can dynamically update the shelf life of food materials placed in the refrigerator 100, thereby improving the accuracy of monitoring whether the food materials are out of date by using the refrigerator 100, and further improving the user experience.
It should be noted that, the electronic tag may be a tag adopting a near field communication (NearFieldCommunication, NFC) technology, or may be a tag adopting a radio frequency identification (RadioFrequencyIdentification, RFID) technology. When the electronic tag is a tag adopting NFC technology, the tag detecting device 30 may be, for example, an NFC antenna; when the electronic tag is a tag using RFID technology, the tag detection apparatus 30 may be, for example, an RFID antenna.
Illustratively, an electronic label is associated with a food material. When a user puts in or takes out food materials in the refrigerator 100, the food materials may be put in or taken out together with an electronic tag associated with the food materials. Illustratively, the information of the electronic tag may include an identification code of the electronic tag. Different electronic tags have different identification codes so that the controller 50 distinguishes between a plurality of electronic tags. The identification code of the electronic tag is written into the chip of the electronic tag before leaving the factory.
In some examples, the identification code of the electronic tag and the information of the food material associated with the electronic tag (e.g., food material name, food material icon, etc.) may be pre-stored in correspondence in the food material database. Accordingly, after the information of the electronic tag is acquired by the tag identifier 30, the controller 50 may query the food database for the information of the food associated with the electronic tag according to the information of the electronic tag. In other examples, a user may manually edit information of food materials associated with an electronic tag when the electronic tag is placed in the refrigerator 100. After the user completes editing, the refrigerator 100 may store information of the electronic tag in correspondence with information of food associated with the electronic tag.
For example, the surfaces of different electronic tags may be provided with different marks (e.g., colors, patterns, etc. corresponding to different kinds of food materials) to facilitate user identification and differentiation. The electronic tag may be, for example, a card. The electronic tag can be clamped on food materials, and can also be attached to packaging bags or packaging boxes of the food materials.
In some examples, the tag detection apparatus 30 is disposed on the cabinet 10 or the door 20. The detection range of the tag detection apparatus 30 covers the entire refrigerator 100 to detect all electronic tags in the refrigerator 100.
When the controller 50 receives the door closing signal from the door opening and closing detecting means 40, it is indicated that the user may have performed the insertion and/or extraction of food materials. At this time, the controller 50 controls the tag detection apparatus 30 to detect all the electronic tags in the refrigerator 100, so as to obtain and record the first tag information set when the door is closed. And then, comparing the first label information set with a second label information set obtained when the door closing signal is received last time to determine whether the user performs food material input or output.
In some examples, the second set of tag information includes a first electronic tag that is not present in the first set of tag information. This means that the user takes the first electronic tag and the first food material associated with the first electronic tag from the refrigerator 100 before closing the door 20 this time. At this time, the controller 50 may update the first food material take-out timing based on the current time of receiving the door closing signal.
In other examples, the first set of tag information includes a second electronic tag that is not present in the second set of tag information. This means that the user will add the second electronic tag and the second food material associated with the second electronic tag before closing the door 20 this time. At this time, the controller 50 updates the time of putting the second food material according to the time of receiving the door closing signal, and updates the shelf life of the second food material according to the time of putting the second food material.
Note that, when the second tag information set includes a first electronic tag that does not exist in the first tag information set, the first tag information set may also include a second electronic tag that does not exist in the second tag information set. This means that the user takes out the first food material and puts in the second food material before closing the door 20 this time. At this time, the controller 50 may update the take-out timing of the first food material, the put-in timing of the second food material, and the shelf life of the second food material, respectively.
For example, after the controller 50 obtains and records the first tag information set when the door 20 is closed, the historical tag information sets except the first tag information set and the second tag information set obtained when the door 20 is closed last time may be deleted to prevent excessive memory from being occupied.
In addition, after the controller 50 updates the shelf life of the second food material, the controller 50 may store the shelf life of the second food material and the second electronic tag in the above-mentioned food material database, and the shelf life of the food material may be shortened as time passes after the update. Or the controller 50 may write the shelf life of the second food material to the second electronic label.
In some examples, the time of receipt of the door closing signal may be taken as the time of removal of the first food material. However, considering the signal processing time of the door opening/closing detecting device 40 and the transmission time of the door closing signal, there is a certain error between the actual taking-out time of the first food material and the receiving time of the door closing signal. Therefore, in other examples, the time of taking out the first food material may be obtained according to the time of receiving the door closing signal, the preset signal processing time and the preset transmission time, so as to improve the accuracy of the time of taking out, and further improve the accuracy of updating the shelf life of the first food material later. For example, the time of taking out the first food material may be obtained by subtracting the preset signal processing time and the preset transmission time from the time of receiving the door closing signal.
It should be noted that, the update method of the time of putting the second food material into the container may refer to the update method of the time of taking the first food material out in the foregoing embodiment, which is not described herein again.
In some embodiments, the refrigerator 100 further includes a label box. The tag cassette is configured to store unused free electronic tags. The label box is internally provided with a label read-write device. The tag read-write device is configured to detect a free electronic tag stored in the tag cassette.
In some examples, the tag read/write device may send information of the idle electronic tag to the controller 50, so that the controller 50 may delete information of food materials, food material taking-out time, food material putting-in time, and the like stored in the idle electronic tag according to the information of the idle electronic tag. Thus, after the user uses the electronic tag, the electronic tag may be returned to the tag box to initialize the data of the electronic tag for the next time for associating with other food materials.
In the following, an exemplary manner in which the controller 50 updates the shelf life of the second food material will be mainly described.
In some embodiments, the controller 50 is configured to:
when the taking-out time of the second food material is empty, acquiring a first temperature of a region where the second food material is located;
and obtaining the expected shelf life of the second food material at the first temperature, and updating the shelf life of the second food material according to the placement time and the expected shelf life of the second food material.
In some examples, the controller 50 may obtain the time of removal of the second food material associated with the second electronic tag after updating the time of placement of the second food material according to the time of receipt of the door closing signal. By determining whether the take-out timing of the second food material is empty, it is possible to determine whether the second food material is put into the refrigerator 100 for the first time or taken out from the refrigerator 100 and then put again. In the case where the take-out timing of the second food material is empty, the controller 50 may determine that the second food material is first put into the refrigerator 100.
At different storage temperatures, the shelf life of the food material will vary considerably. In this embodiment, when the second food material is first placed in the refrigerator 100, the expected shelf life of the second food material may be obtained according to the first temperature of the area where the second food material is located, and then the shelf life of the second food material is updated according to the placement time and the expected shelf life of the second food material, so that the accuracy of the shelf life of the second food material recorded in the refrigerator 100 may be improved.
In some examples, the controller 50 may take the set temperature of the region where the second food material is located as the first temperature. The area where the second food material is located is illustratively a compartment such as a "freezer compartment", "refrigerator compartment", "variable temperature compartment", etc. The set temperature of the area where the second food material is located may be a default value in factory setting of the refrigerator 100, or may be a set value of a user. In other examples, the refrigerator 100 further includes a plurality of temperature sensors disposed in different compartments of the refrigerator 100 and configured to detect temperatures of the different compartments. In this example, the controller 50 may acquire the temperature detected by the temperature sensor in the same chamber as the second food material, and use the temperature as the first temperature.
In some examples, as shown in table 1, a predicted shelf life lookup table is stored in the refrigerator 100 in advance, and the predicted shelf life lookup table records a correspondence relationship between food materials, temperatures and predicted shelf lives so as to reflect different predicted shelf lives of various food materials at different temperatures. At this time, the controller 50 may query the estimated shelf life of the second food material from the estimated shelf life lookup table according to the food material information (e.g., the food material name) and the first temperature of the second food material. In other examples, the correspondence between different expected shelf lives of various food materials at some temperatures may be used as a training sample set in advance to train the neural network model to obtain the shelf life prediction model. The shelf life prediction model can predict different predicted shelf lives of various food materials at different temperatures. At this time, the controller 50 may input the food material information and the first temperature of the second food material into the shelf life prediction model to obtain the predicted shelf life of the second food material.
TABLE 1 correspondence between food materials, temperature and predicted shelf-life
In other embodiments, with continued reference to fig. 1, the refrigerator 100 further includes: a temperature detection device 70. The temperature detecting device 70 is coupled to the controller 50 and is configured to detect an ambient temperature in which the refrigerator 100 is located.
The controller 50 is configured to:
When the first condition is satisfied, the average ambient temperature in the period from the time when the second food is taken out to the time when the second food is put in is acquired by the temperature detecting device 70; the first condition includes that the taking-out time of the second food material is not empty;
acquiring a first shelf life influence time of the second food material according to the average ambient temperature;
and updating the shelf life of the second food material according to the first shelf life influence time.
In this embodiment, when the time of taking out the second food material is not empty, the controller 50 may confirm that the second food material is taken out from the refrigerator 100 and then put into the refrigerator 100 again. Since the temperature of the environment in which the refrigerator 100 is located is generally higher than the temperature of the inside of the refrigerator 100, and the change in the storage temperature causes the shelf life of the food, the controller 50 obtains the average temperature of the environment in the period from the time of taking out the second food to the time of putting in the second food through the temperature detecting device 70, and then updates the shelf life of the second food by using the first shelf life influence time obtained according to the average temperature, so that the accuracy of the shelf life of the second food recorded by the refrigerator 100 can be further improved.
In some examples, the refrigerator 100 stores a first shelf life influence time lookup table in advance, where the first shelf life influence time lookup table records a correspondence relationship between food materials, temperature, and first shelf life influence time to reflect different first shelf life influence times of various food materials at different temperatures. At this time, the controller 50 may query the first shelf life influence time lookup table for the second food material according to the food material information of the second food material and the average ambient temperature. In other examples, the correspondence between different first-shelf-life influence times of various food materials at some temperatures may be used as a training sample set in advance to train the neural network model to obtain the first-shelf-life influence time prediction model. The first shelf life influence time prediction model can predict different first shelf life influence times of various food materials at different temperatures. At this time, the controller 50 may input the food material information of the second food material and the average ambient temperature into the first shelf life influence time prediction model, and obtain the first shelf life influence time of the second food material.
In some examples, the controller 50 may add the pre-update shelf life of the second food material to the first shelf life influencing time described above to obtain the updated shelf life of the second food material. Illustratively, if the shelf life of the second food material placed outside the refrigerator 100 is shorter than the shelf life placed inside the refrigerator 100, the above-described first shelf life influence time is negative. Or if the shelf life of the second food material placed outside the refrigerator 100 is longer than the shelf life placed inside the refrigerator 100, the first shelf life influencing time is a positive value.
In still other embodiments, with continued reference to fig. 1, the refrigerator 100 further includes a humidity detection device 80. The humidity detection device 80 is coupled to the controller 50 and is configured to detect the ambient humidity in which the refrigerator 100 is located.
The controller 50 is configured to:
When the first condition is satisfied, the humidity detection device 80 obtains the average ambient humidity in the period from the time when the second food material is taken out to the time when the second food material is put in; the first condition includes that the taking-out time of the second food material is not empty;
Acquiring a second shelf life influence time of a second food material according to the average ambient humidity;
And updating the quality guarantee period of the second food material according to the second quality guarantee period influence time.
In this embodiment, when the time of taking out the second food material is not empty, the controller 50 may confirm that the second food material is taken out from the refrigerator 100 and then put into the refrigerator 100 again. Since the ambient humidity of the refrigerator 100 is generally higher than the internal humidity of the refrigerator 100 and the change of the storage temperature causes the shelf life of the food materials to change, the controller 50 obtains the average ambient humidity from the time of taking out the second food materials to the time of putting in the second food materials through the humidity detection device 80, and then updates the shelf life of the second food materials using the second shelf life influence time obtained according to the average ambient humidity, so that the accuracy of the shelf life of the second food materials recorded by the refrigerator 100 can be further improved.
It should be noted that, regarding the manner in which the controller 50 obtains the second shelf life influence time and obtains the shelf life of the second food product after being updated, reference may be made to the description of the manner in which the controller 50 obtains the first shelf life influence time and obtains the shelf life of the second food product after being updated in the foregoing embodiment, which is not described herein.
In some examples, the first condition in the above two embodiments further includes that a period of time from a take-out time of the second food material to a put-in time of the second food material is greater than a preset first threshold.
Since the short-time taking out of the second food material has a smaller influence on the shelf life of the second food material, the refrigerator 100 in this embodiment can avoid the controller 50 from updating the shelf life of the food material with a shorter taking-out time by setting the time period from the taking-out time of the second food material to the putting-in time of the second food material to be larger than the preset first threshold value, thereby reducing the occupation of computing resources and reducing the power consumption.
In still other embodiments, the controller 50 is further configured to:
Acquiring a first temperature of a region where the second food material is located when the first tag information set comprises a second electronic tag which does not exist in the second tag information set and the taking-out time of the second food material is not empty;
Judging whether the difference between the first temperature and the second temperature is larger than a preset second threshold value or not; the second temperature is the temperature of the area where the second food material is located before the second food material taking-out time;
if the difference is greater than a second threshold, acquiring a third shelf life influence time of the second food according to the difference;
And updating the quality guarantee period of the second food material according to the third quality guarantee period influence time.
During use of the refrigerator 100, a user may take food from the compartment a and put it back into the compartment B, and the temperature of the compartment A, B is generally different, and the shelf life of the food may be changed. Therefore, in the case where the time of taking out the second food material is not empty, the refrigerator 100 in the above embodiment may determine the third shelf life influence time of the second food material according to the difference between the first temperature of the area where the second food material is currently located and the second temperature of the area located before the time of taking out the second food material, and update the shelf life of the second food material according to the third shelf life influence time, so that the accuracy of the shelf life of the second food material may be further improved.
In some examples, a third shelf life influence time lookup table is pre-stored in the refrigerator 100 to reflect the influence time of different temperature differences on shelf life of various food materials. At this time, the controller 50 may query the corresponding relationship for the third shelf life influence time of the second food material according to the difference between the first temperature and the second temperature and the information of the second food material. In other examples, the controller 50 may also input the difference between the first temperature and the second temperature and the information of the second food material into the trained neural network model to obtain the third shelf life impact time of the second food material.
It should be noted that, regarding the training manner of the neural network model and the manner of the controller 50 obtaining the updated shelf life of the second food material, reference may be made to the related content of the foregoing embodiment, which is not described herein again.
Next, by way of a specific example, the shelf life update process of the above-described food materials is exemplified.
As shown in fig. 3, after the user puts the second food material into the refrigerator 100 and closes the door, the door opening and closing detecting device 40 transmits a door closing signal to the controller 50. After receiving the door closing signal, the controller 50 obtains information of all electronic tags in the box 10 through the tag detection device 30, and obtains a first tag information set when the door is closed. Then, the controller 50 acquires the second tag information set when the door is closed last time, and determines that the first tag information set includes information of a second electronic tag that does not exist in the second tag information set by comparing the first tag information set with the second tag information set. At this time, the controller 50 determines the time of taking out the second food material associated with the second electronic tag according to the time of receiving the door closing signal, and acquires the time of taking out the second food material.
If the second food material is taken out at the empty time, it is indicated that the second food material is first put into the refrigerator 100, at this time, the controller 50 obtains and records the first temperature T1 of the area where the second food material is located, and inputs the information of the second food material into the shelf life prediction model to obtain the predicted shelf life D of the second food material at the first temperature T1, and finally updates the shelf life of the second food material to be D.
If the second food material is not empty, it is indicated that the second food material is taken out and then put into the refrigerator 100, and at this time, the controller acquires a time period t from the time of taking out the second food material to the time of putting in, and acquires an average ambient temperature and an average ambient humidity in the time period t through the temperature detecting device 70 and the humidity detecting device 80. Then, the controller 50 obtains the first shelf life influence time D1 and the second shelf life influence time D2 of the second food material by querying according to the average ambient temperature and the average ambient humidity. Then, the controller 50 obtains a second temperature T2 of the area where the second food material is located before the take-out time, and determines whether an absolute value |t1—t2| of a difference between the first temperature T1 and the second temperature T2 is greater than a second threshold T0. If so, it is indicated that the temperature difference between the first temperature T1 and the second temperature T2 is larger, and at this time, the controller 50 obtains the third shelf life influence time D3 of the second food according to the difference between the first temperature T1 and the second temperature T2, and finally updates the shelf life of the second food to d+d1+d2+d3. If not, it is indicated that the temperature difference is smaller, and the controller 50 updates the shelf life of the second food material to d+d1+d2.
