In some embodiments, the food material information in the local data includes a food material shelf life and a food material put-in time, from which the freshness of the food material can be monitored, such as a remaining shelf life, an expiration time, and the like of the food material. In order to remind the user of the freshness degree of each food material, the freshness identifier of the food material can be displayed in the food material management interface, and if the freshness identifier of the food material is loaded in the corresponding food material control for display, the freshness degree of the food material is reminded for the user.
In some embodiments, the freshness identifier of the food material may specifically be a progress bar representing the freshness degree of the food material; in other embodiments, the freshness indicator of the food material may be a text indicator directly indicating the remaining shelf life of the food material. In the embodiments, the food materials are indiscriminately displayed in the form of progress bars or character marks, so that it is not very convenient for a user to directly distinguish which food materials are overdue, which food materials are about to be overdue, which food materials are relatively fresh, and the like, and the user experience is not friendly enough.
In some embodiments, the controller of the refrigerator is configured to: the method comprises the steps of obtaining food material information corresponding to each food material in a storage chamber from local data, generating a food material management interface according to the food material information corresponding to each food material, wherein the food material management interface comprises a food material control corresponding to each food material, displaying a food material icon and a freshness identification of the food material in the food material control, generating the food material icon according to a preset food material icon material corresponding to a food material name, and also generating a custom icon according to the food material name, wherein the freshness identification of the food material is used for indicating the freshness of the food material, the freshness identification of the food material is generated into different states according to different freshness of the food material, the freshness of the food material can be determined according to the input time and the quality guarantee period of the food material, and the input time and the quality guarantee period of the food material are contained in the food material information.
In the above embodiments, the freshness degree of the food material may be quantitatively characterized by the remaining shelf life and/or the freshness ratio of the food material. The remaining quality guarantee period of the food material can be calculated according to the quality guarantee period of the food material, the food material putting time and the current time, specifically, the remaining quality guarantee period of the food material is the food material quality guarantee period- (the current time-the food material putting time), and when the remaining quality guarantee period of the food material is less than 0, the food material is overdue; the ratio of the fresh ratio of the food materials, namely the ratio of the residual quality guarantee period of the food materials to the quality guarantee period of the food materials is less than or equal to 100%, and the longer the residual quality guarantee period of the food materials is, the closer the fresh ratio of the food materials is to 100%, which means that the food materials are fresher.
In the case of a factory-type food such as milk or yogurt, the production time thereof may be used as the food material loading time for storage. According to different specific food materials, the food material placing time mentioned in the embodiment of the present application includes, but is not limited to, the food material generating time or the time when the user places the food material into the refrigerator for the first time.
In some embodiments, when the remaining shelf life of the food material is less than zero, generating the freshness identifier into a first state to remind the user that the food material is expired by using the freshness identifier of the first state; when the freshness proportion is not less than the preset value, the freshness identification is generated to be in a second state, so that the freshness identification in the second state is used for reminding a user that the food material is relatively fresh; and when the freshness ratio is smaller than the preset value, generating the freshness identification into a third state so as to remind the user that the food material is about to expire by using the freshness identification in the third state.
It should be noted that the preset value may be set by a user according to a requirement, for example, set to 33%.
Compared with a scheme of indiscriminately displaying the optional freshness of the food materials in a progress bar or character identification mode, the freshness identification of the food materials is generated to be in different states when the freshness of the food materials is different, so that a user can more intuitively distinguish which food materials are expired, which food materials are about to expire, which food materials are fresh and the like, and the user can more conveniently and quickly acquire information which the user wants to pay attention to, for example, the user can quickly find the expired food materials according to the freshness identification in the first state, or quickly find the food materials which are about to expire according to the freshness identification in the third state and the like.
In some embodiments, the freshness indicator of the first state is a first picture indicator floating on the food material icon, and the first picture indicator covers the food material icon. The first picture identifier may display a symbol or a text indicating that the food material is expired, such as "expired". As a possible implementation manner, when the remaining shelf life is less than zero, a first picture identifier is generated in a first preset area of a first layer above the food material icon, and the first preset area overlaps with a display area of the food material icon, so that the food material icon is partially covered by the first picture identifier. As a possible implementation manner, the transparency of the first icon identifier is greater than 0% so that the food material icon can be displayed through the first picture identifier.
Fig. 4 is a freshness indicator of a first state, specifically an exemplary first picture indicator, shown in the present application according to an exemplary embodiment. As shown in fig. 4, a text prompt of "expired" is displayed in the first picture identifier 401, the first picture identifier 401 floats on the food material icon 402 to be displayed, and partially covers the food material icon 402, and since the transparency of the first picture identifier 401 is greater than 0%, the covered portion of the food material icon 402 can still be displayed through the first picture identifier 401, so that the first picture identifier is sufficiently striking, a user can conveniently and quickly notice the expired food material, and the user is not influenced to recognize the food material through the food material icon.
In some embodiments, the freshness indicator of the second state is a second progress indicator displayed in a second preset area. Specifically, when the fresh proportion is not smaller than the preset value, a second progress mark is generated in a second preset area of the second layer. The second preset area is an area which does not overlap with the display area of the food material icon, such as a gap area between the food material icon and the food material name.
In some embodiments, the second progress indicator may specifically be a progress bar including a progress region and a background region, a length of the progress region represents a progress value, the progress value corresponds to a freshness ratio, and the progress region and the background region are filled with different colors to realize explicit distinction of the two regions. As a possible implementation manner, the progress area of the second progress indicator is configured to be different colors according to the difference of the numerical value range in which the freshness ratio falls. For example, when the fresh proportion of the food material is higher than the first value, the progress area of the second progress mark is configured to be green, and when the fresh proportion of the food material is lower than the first value, the progress area of the second progress mark is configured to be yellow. The first value is greater than 0 and less than the preset value, for example, the first value is preset to 66%, when the fresh proportion e of the food material is (33%, 66%), the progress area of the second progress mark is configured to be yellow, and when the fresh proportion e of the food material is (66%, 100%), the progress area of the second progress mark is configured to be green.
Therefore, the user can judge the freshness of the food material according to the length of the progress area and can judge the freshness of the food material according to the color of the progress area, the user can conveniently and quickly notice the fresh food material (for example, the progress area of the progress bar shows green food material), and the user can also conveniently notice the less fresh food material (for example, the progress area of the progress bar shows yellow food material).
Fig. 5 is a freshness indicator of a second state, specifically an exemplary second progress indicator, according to an exemplary embodiment of the present application. As shown in fig. 5, the second progress marker 501 displays a gap area between the food material name 502 and the food material icon 503, the second progress marker 501 does not overlap with the food material name 502 and the food material icon 503, the second progress marker 501 includes a progress area and a background area, and the progress area and the background area are filled with different colors.
Fig. 6 is a freshness indicator of another second state, specifically another exemplary second progress indicator, shown according to an exemplary embodiment of the present application.
