Fig. 1 shows a schematic structural diagram of an alternative refrigerator door, which includes 9 display areas distributed in a grid shape (3 × 3). Each display area can be displayed separately, for example, the first display area displays related content, and other display areas are in a black screen state; or the fifth display area displays the related content, and other display areas are in a black screen state. In addition, a plurality of adjacent display areas can also be displayed in any combination, for example, the first display area and the second display area are combined to display related content, and other display areas are in a black screen state; or the first display area, the second display area, the fourth display area and the fifth display area are combined to display related content, and other display areas are in a black screen state; or the nine display areas of the display screen jointly display the related content. Due to the fact that the different display areas are different in arrangement position, the display height of the display content displayed on the refrigerator door body can be adjusted by controlling the different display areas to display.
The embodiment of the present disclosure provides a control method for a refrigerator, as shown in fig. 2, including the following steps:
s201: height information of the user is obtained.
Optionally, obtaining height information of the user comprises: the height information of the user is obtained by obtaining the input information of the user. In practical application, the user can input the height information by means of an input key or mobile phone software and the like. Therefore, the input mode is more flexible, and the input height information is more accurate.
Optionally, obtaining height information of the user comprises: acquiring identity information of a user; height information corresponding to the identity information is obtained. In practical application, the identity information of the user is obtained by identifying the facial image of the user, and then the height information of the user is obtained through a preset corresponding table of the identity information of the user and the height information. Therefore, the height information of the user is automatically obtained, manual input of the user is not needed, and the user experience is better.
S202: and determining the display height of the display content displayed on the refrigerator door body according to the height of the user.
In some embodiments, determining the display height of the display content displayed on the refrigerator door body according to the height of the user comprises: and determining the display height corresponding to the height of the user according to the preset corresponding relation.
The preset corresponding relation (first corresponding relation) is used for indicating the corresponding relation between the display height of the display content displayed on the refrigerator door body and the height of the user. After the height information of the user is obtained, the display height corresponding to the height of the user can be obtained by searching the preset corresponding relation table.
For example, table 1 shows a table of correspondence between selectable display heights and user heights, from which it can be known that: when the height of the user is 70cm, the display height of the display content displayed on the refrigerator door body is a second height; and when the height of the user is 220cm, the display height of the display content displayed on the refrigerator door body is a fifth height.
Table 1: table for displaying corresponding relation between height and user height
| User height (Unit: cm) | Display height |
| (0，60] | First height |
| (60，90] | Second height |
| (90，150] | Third height |
| (150，180] | A fourth height |
| (180，+∞) | A fifth height |
And displaying the refrigerator height with the height being a preset proportion. For example, the first height is one sixth of the refrigerator height; the second height is the refrigerator height of two sixths; the third height is three-sixths of the height of the refrigerator; the fourth height is the refrigerator height of four sixths; the fifth height is a refrigerator height of five sixths. When the height of the refrigerator is 180cm (centimeter), the first height is 30cm, the second height is 60cm, the third height is 90cm, the fourth height is 120cm, and the fifth height is 150 cm.
In some embodiments, determining the display height of the display content displayed on the refrigerator door body according to the height of the user further comprises: and after the display height corresponding to the height of the user is determined, the display height is adjusted according to the distance between the user and the door body.
When the distance between the user and the door body is different for the same user, the optimum display height of the user is different. When the user is far away from the door body (namely, the distance between the user and the door body is larger), the display height of the display content on the door body of the refrigerator is higher, and the viewing angle of the user is better; when the user is close to the door body (i.e. the distance between the user and the door body is small), the display height of the display content on the door body of the refrigerator is low, and the user watching experience is better. Therefore, after the display height corresponding to the height of the user is determined, the display height of the display content is adjusted according to the distance between the user and the door body, and the viewing experience of the user for viewing the related display content is improved.
Optionally, as shown in fig. 3, adjusting the display height according to the distance includes the following steps:
s2021: and obtaining a distance difference value between the distance between the user and the door body and the preset distance.
The preset distance is a distance (e.g., 70cm) between the door body when the user views the display content under normal circumstances. The distance difference can be calculated by the following formula:
ΔL＝L-L0
wherein, DeltaL is a distance difference value, L is a distance between a user and a door body, and L is a distance between the user and the door body0Is a preset distance.
S2022: a height adjustment value corresponding to the distance difference is obtained.
Optionally, the height adjustment value corresponding to the distance difference is determined according to a preset corresponding relationship.
The preset correspondence (second correspondence) is used to indicate a correspondence between the height adjustment value and the distance difference value. After the distance difference is obtained, a height adjustment value corresponding to the distance difference can be obtained by searching a preset corresponding relation table. For example, table 2 shows an alternative table of height adjustment values versus distance differences:
table 2: corresponding relation table of height adjustment value and distance difference value
| Distance difference DeltaL (unit: cm) | Height adjustment value Δ H (unit: cm) |
| (-∞，-50] | -15 |
| (-50，-30] | -10 |
| (-30，-10] | -5 |
| (-10，10] | 0 |
| (10，30] | 20 |
| (30，50] | 30 |
| (50，+∞) | 35 |
According to the corresponding relation table, it can be known that: when the distance difference is 20cm, the height adjustment value is 20 cm; when the distance difference is 5cm, the height adjustment value is 0 cm.
S2023: and adjusting the display height according to the height adjustment value.
The adjusted display height can be calculated by the following formula:
H＝0+ΔH
wherein H is the adjusted display height, H0To show the height, Δ H is a height adjustment value.
For example, the display height of the display content displayed on the door body of the refrigerator is determined to be the second height (60cm) according to the height (70cm) of the user. And obtaining the distance between the user and the door body to be 90cm by means of infrared distance measurement and the like, and obtaining the corresponding height adjustment value to be 20cm when the distance difference between the distance between the user and the door body and the preset distance (70cm) is 20cm through calculation. The adjusted display height is 60cm +20cm, which is 80cm, and is closest to the third height (90cm), which is the third height.
S203: and displaying according to the determined display height.
Optionally, the displaying according to the determined display height includes: determining a display area corresponding to the display height according to a preset corresponding relation; and controlling the determined display area to display the related display content.
The preset correspondence (third correspondence) is used to indicate a correspondence of the display area to the display height. After the display height is obtained, the display area corresponding to the display height can be obtained by searching a preset corresponding relation table. For example, table 3 shows a table of correspondence between selectable display areas and display heights:
table 3: correspondence table of display area and display height
| Display height | Display area |
| First height | A seventh display area |
| Second height | Fourth, fifth, seventh and eighth display areas |
| Third height | A fifth display area |
| A fourth height | Fourth, fifth, seventh and eighth display areas |
| A fifth height | A third display area |
According to the corresponding relation table, it can be known that: when the display height is the second height, the display areas are a fourth display area, a fifth display area, a seventh display area and an eighth display area; when the display height is the third height, the display area is a fifth display area.
In the embodiment of the disclosure, the display height of the display content displayed on the refrigerator door body is determined according to the height of the user, and the display content is displayed according to the determined display height, so that the user with different shapes can conveniently look up the display content.
In some embodiments, the display height is a height of a center position of the display content. The center position of the display content is set at the most suitable viewing height of the user, and the experience of the user in viewing the display content is better.
In some embodiments, as shown in fig. 4, the control method for the refrigerator further includes the steps of:
s401: identity information of the user is obtained.
The identity information of the user includes children, female middle-aged persons, male middle-aged persons, or elderly persons. In practical applications, the identity information of the user may be obtained by recognizing a facial image of the user.
S402: and obtaining and displaying display content corresponding to the identity information.
Optionally, obtaining the display content corresponding to the identity information comprises: determining keywords of the display content corresponding to the identity information; and searching and obtaining display content corresponding to the keywords.
Optionally, determining the keywords of the display content corresponding to the identity information comprises: and determining keywords corresponding to the display content of the identity information according to the preset corresponding relation.
Optionally, the display content includes a display image of a storage area of the refrigerator and recommendation information related to the food material.
The preset correspondence (fourth correspondence) is used to indicate a correspondence between the keyword of the display content and the identity information. After the identity information is obtained, the keyword corresponding to the display content of the identity information can be obtained by searching a preset corresponding relation table. For example, table 4 shows a table of correspondence between keywords of selectable display contents and identity information:
table 4: correspondence table for displaying keywords of content and identity information
| Identity information | Displaying keywords of an image | Keyword for recommending information |
| Children's toy | 'dessert' | Food learning " |
| Female middle-aged man | Cosmetics and mother and baby " | Menu recommendation " |
| Middle-aged man | Cold drink " | Menu recommendation " |
| Old people | Medicine " | Health-preserving suggestion " |
According to the corresponding relation table, it can be known that: when the display content is a display image of a storage area of the refrigerator, the keyword corresponding to the child is a "dessert"; when the displayed content is recommendation information related to food materials, the keyword corresponding to the child is "food material learning".
Each storage area in the refrigerator is divided into different functional areas such as a dessert area, a cosmetic area, a mother and infant area, a cold drink area and the like. Each functional area is provided with a camera device for acquiring image information in the area. When the keyword corresponding to the child is determined to be the 'dessert', obtaining a display image of the dessert region for display; when the keyword corresponding to the child is determined to be food learning, video or image information related to the food learning is obtained through the search platform and displayed. The method and the device not only can facilitate users with different identities to check the internal storage state of the refrigerator storage area in which the users are interested, but also facilitate the users to know more interested information related to food materials.
S403: and adjusting the display area of the display content according to the distance between the user and the door body.
Optionally, when a distance difference between the distance between the user and the door body and the preset distance is greater than the preset distance difference, the display area of the display content is increased.
Alternatively, the display area of the display content is increased by increasing the number of display regions of the same height.
For example, if the preset distance difference is 15cm, the distance between the user and the door is 90cm, and the distance difference between the distance between the user and the door and the preset distance (70cm) is 20cm, the display area of the display content is increased. In practical applications, when the display height is the third height, as can be seen from table 3, if the display area is the fifth display area, the adjusted display areas are the fourth display area and the fifth display area, or the fifth display area and the sixth display area, or the fourth display area, the fifth display area and the sixth display area.
The display area of the display content is adjusted according to the distance between the user and the door body, so that the user at different distances from the refrigerator door body can see the display content on the refrigerator door body more clearly, and the user experience is better.
In some embodiments, the control method for a refrigerator further includes the steps of: and determining the display brightness of the display content according to the distance between the user and the door body.
Optionally, determining the display brightness of the display content according to the distance includes: and determining the display brightness corresponding to the distance according to the preset corresponding relation.
The preset corresponding relation (fifth corresponding relation) is used for indicating the corresponding relation between the display brightness and the distance between the user and the refrigerator door body. After the distance between the user and the refrigerator door body is obtained, the display brightness corresponding to the distance can be obtained by searching a preset corresponding relation table. For example, table 5 shows an alternative display brightness versus distance table:
table 5: display brightness and distance corresponding relation table
| Distance (Unit: cm) | Display brightness |
| (0，50] | First brightness |
| (50，70] | Second brightness |
| (70，100] | Third brightness |
| (100，180] | Fourth brightness |
| (180，+∞) | Fifth brightness |
According to the corresponding relation table, it can be known that: when the distance between the user and the refrigerator door body is 70cm, the display height is second brightness; and when the distance between the user and the refrigerator door body is 200cm, the display height is fifth brightness.
Optionally, in the preset corresponding relationship between the display brightness and the distance, the display brightness is positively correlated with the distance between the user and the refrigerator door body, that is, the larger the distance between the user and the refrigerator door body is, the larger the display brightness is. In the correspondence table of display luminance and distance, for the display luminance of the door body: first luminance < second luminance < third luminance < fourth luminance < fifth luminance.
The display area of the display content is adjusted according to the distance between the user and the door body, the larger the distance is, the larger the display brightness is, the more clear the display content on the refrigerator door body can be seen by the user with different distances from the refrigerator door body, and the better the user experience is.
