[0055] The electronic paper 30 is provided on the door shell outside the box 10, and the electrode wires of the electronic paper 30 are connected to the controller 40;

[0056] The controller 40 is configured to obtain image data sent by the mobile terminal and perform color recognition on the image data to obtain candidate colors; wherein the image data includes a refrigerator and the environment in which the refrigerator is located; determine the target color of the electronic paper 30 based on the candidate colors and the preset color of the electronic paper 30; and control the output voltage of the electronic paper 30 according to the target color so that the electronic paper 30 displays the corresponding color.

[0057] Specifically, the refrigerator provided by the embodiment of the present invention includes a housing 10, a refrigeration system 20, an electronic paper 30 and a controller 40. Figure 2 , Figure 2 It is a structural diagram of a refrigerator body provided by one embodiment of the present invention. The refrigerator in this embodiment has an approximately rectangular parallelepiped shape, and the refrigerator includes a body 10 that defines a storage space. The body 10 serves as the supporting structure of the refrigerator, and is provided with a cavity inside, wherein the cavity includes a component storage cavity for placing components in the refrigerator, such as a compressor, etc., and also includes a storage space for storing food, etc. The storage space can be divided into a plurality of storage rooms (i.e., compartments), and the storage rooms can be configured as a refrigeration room, a freezer room, or a temperature-changing room (also called a fresh-keeping room) according to different uses. One or more door bodies 200 are provided at the opening of each storage room, for example, Figure 2The upper storage compartment is a refrigerator, with a double-door structure. The door 200 comprises a door shell 210 located outside the box 10, a door inner liner 220 located inside the box 10, an upper end cover 230, a lower end cover 240, and an insulation layer located between the door shell 210, the door inner liner 220, the upper end cover 230, and the lower end cover 240. Typically, the insulation layer is made of foam. The door can be pivotally mounted at the opening of the box or opened in a drawer-like manner to enable drawer-style storage.

[0058] The refrigerator performs refrigeration operation through the refrigeration system, providing cold energy to the compartment to maintain the compartment at a constant low temperature. Specifically, the refrigeration system of the refrigerator in this embodiment can be a single refrigeration system or a dual refrigeration system. Figure 3 , Figure 3 The figure is a schematic diagram of the structure of a refrigerator refrigeration system according to one embodiment of the present invention. The refrigerator refrigeration system according to this embodiment includes a compressor 1, a condenser 2, an anti-condensation tube 3, a filter drier 4, a capillary tube 5, an evaporator 6, and a gas-liquid separator 7. The refrigeration system operates through compression, condensation, throttling, and evaporation.

[0059] The compression process is as follows: when the refrigerator is plugged in and there is a cooling demand on the cabinet, the compressor 1 starts working, low-temperature, low-pressure refrigerant is sucked into the compressor, compressed into high-temperature, high-pressure superheated gas in the cylinder of the compressor 1, and then discharged into the condenser 2;

[0060] The condensation process is as follows: the high-temperature, high-pressure refrigerant gas dissipates heat through the condenser 2, the temperature continues to drop, and it is gradually cooled to a saturated vapor at room temperature and high pressure. It is further cooled to a saturated liquid, and the temperature no longer drops. The temperature at this point is called the condensation temperature. The pressure of the refrigerant remains almost unchanged throughout the condensation process.

[0061] The throttling process is as follows: the condensed refrigerant saturated liquid passes through the drying filter 4 to remove moisture and impurities and flows into the capillary tube 5, through which throttling and pressure reduction are carried out, and the refrigerant becomes wet steam at room temperature and low pressure;

[0062] The evaporation process is as follows: it then begins to absorb heat and vaporize in the evaporator 6, which not only reduces the temperature of the evaporator and its surroundings, but also turns the refrigerant into a low-temperature, low-pressure gas. The refrigerant coming out of the evaporator 6 passes through the gas-liquid separator 7 and returns to the compressor 1 again. The above process is repeated to transfer the heat in the refrigerator to the air outside the box, thereby achieving the purpose of refrigeration.

[0063] The fan allows air to continuously enter the fins of the evaporator 6 for heat exchange, and at the same time sends the cooled air after the evaporator 6 releases heat into the refrigerator room through the air duct, so that the air in the room continuously circulates to achieve the purpose of lowering the temperature.

[0064] See also Figure 4 , Figure 4 The figure is a schematic structural diagram of a dual refrigeration system for a refrigerator provided in one embodiment of the present invention. The dual refrigeration system of the refrigerator described in this embodiment of the present invention includes a compressor 21 for compressing the refrigerant, a first capillary tube 14a and a second capillary tube 14b for decompressing the refrigerant, a refrigeration evaporator 15a and a freezing evaporator 15b as heat absorption mechanisms, a three-way valve 17 for controlling the refrigerant flow path, a one-way valve 18 for preventing refrigerant backflow, a dryer 19 for removing moisture from the refrigeration cycle, and a refrigerant junction 13 for connecting the refrigerant flow paths. These are connected by a pipe 20 to circulate the refrigerant, forming a refrigeration cycle. During this process, fans 12a and 12b, respectively provided for each storage compartment, are used to increase the air flow rate, thereby increasing the speed at which the refrigeration evaporator and the freezing evaporator absorb heat, thereby improving the cooling speed of the storage compartment. The three-way valve 17 has a first outflow port 17a and a second outflow port 17b. When the three-way valve 17 is controlled to open the first outflow port 17a, the refrigerant flows sequentially through the first capillary tube 14a, the refrigeration evaporator 15a, the gas-liquid separator 16a, and the refrigerant junction 13, before returning to the compressor 21. After passing through the first capillary tube 14a, the low-pressure, low-temperature refrigerant flows through the refrigeration evaporator 15a, exchanging heat with the refrigeration evaporator 15a and the air in the refrigeration compartment 110, thereby cooling the refrigeration compartment 110. Similarly, when the three-way valve 17 is controlled to open the second outflow port 17b, the refrigerant flows sequentially through the second capillary tube 14b, the freezing evaporator 15b, the gas-liquid separator 16b, and the refrigerant junction 13, before returning to the compressor 21. After passing through the second capillary tube 14b, the low-pressure, low-temperature refrigerant flows through the freezing evaporator 15b, exchanging heat with the freezing evaporator 15b and the air in the freezer compartment 120, thereby cooling the freezer compartment 120.

[0065] See also Figure 5 , Figure 5The figure is a schematic diagram of the exterior appearance of a refrigerator provided by one embodiment of the present invention. In this embodiment, electronic paper 30 is mounted on the door housing 210 outside the housing 10, and the electrode wires of the electronic paper 30 are connected to a controller 40. The electronic paper supports different voltage modulations based on a base color to display different colors. The color-changing principle of color-changing electronic paper is that by applying different voltages to the electronic paper, the differently colored capsule particles within the electronic paper move and combine, resulting in the appearance of different colors. Therefore, after adding electronic paper to the refrigerator panel, the electronic paper electrode wires are connected to the controller. The controller transmits different voltage values ​​to the electronic paper, controlling the color change of the electronic paper pattern while maintaining the base color of the electronic paper. This achieves the color change of the pattern on the refrigerator panel. The controller 40 captures image data sent by a mobile terminal and uses an image recognition algorithm to perform color recognition on the image data, analyzing the color of the home cabinet or surrounding environment to obtain candidate colors. For example, a dominant color histogram method is used to calculate the proportion and probability of different colors in the entire image. The most frequently occurring color is selected as the dominant color of the image, i.e., the candidate color to be displayed by the electronic paper. The image data includes the refrigerator and the environment in which it is located. Since the electronic paper is pre-set with some supported colors, the target color of the electronic paper is determined based on the candidate colors and the preset colors of the electronic paper. For example, the characteristics of the identified primary color, such as the RGB value or HSV value, are compared with the characteristics of the colors supported by the electronic paper. The color with the closest RGB value or HSV value among the preset colors is recommended, which is the target color that the electronic paper can display. Based on the target color, the electrode end of the electronic paper is controlled to output a voltage corresponding to the target color, causing the electronic paper to display the corresponding color, achieving color change of the pattern on the electronic paper, so that the refrigerator displays a color effect similar to that of a home.

[0066] It should be noted that the mobile terminal in the embodiment of the present invention includes but is not limited to mobile phones and tablets. In view of the trend of home integration, after placing the refrigerator and the home together, the mobile terminal can be used to take a picture of the overall effect of the refrigerator and the home around the refrigerator, and the picture can be sent to the controller, so as to achieve a color change effect according to the user's home style. In addition, in the embodiment of the present invention, the mobile terminal can also perform color recognition on the image data to obtain candidate colors. According to the candidate colors and the preset colors of the electronic paper set on the mobile terminal, the target color of the electronic paper is determined, and the user is prompted to modify the refrigerator pattern to the corresponding color through system comparison. After the user confirms, the mobile terminal sends the corresponding color instruction of the selected target color to the controller. The controller receives the color instruction and drives the voltage value of the color and sends it to the electrode end of the electronic paper, so that the electronic paper is refreshed to the corresponding color, so that the refrigerator panel shows an effect close to the color of the home environment.

[0067] The embodiment of the present invention controls the color change of the refrigerator panel by adding color-changing electronic paper to the outer shell of the refrigerator door. It has low cost and low power consumption, and can change the panel color according to the refrigerator environment, effectively improving user experience and refrigerator intelligence.

[0068] As one of the optional embodiments, the electronic paper 30 is fixed between the glass panel 250 of the door body shell 210 and the door body liner 220, and the electronic paper 30 is fixed to the glass panel 250 by optical glue. After being fixed, the electronic paper 30 and the glass panel 250 are foamed with the door body liner 220; wherein, the size of the electronic paper 30 is smaller than the size of the glass panel 250, and the area of ​​the glass panel 250 not adhered to the electronic paper 30 is silk-screened with the same color as the base color of the electronic paper 30.

[0069] For details, please refer to Figure 6 , Figure 6This is a schematic diagram of the position of an electronic paper in a refrigerator provided by an embodiment of the present invention. In order to realize that the color-changing characteristics of the electronic paper can be displayed on the panel, it is necessary to pass through the glass panel on the refrigerator. However, if the electronic paper is placed on the outside of the existing refrigerator glass panel, the electronic paper also needs to be waterproof and moisture-proofed. Therefore, the electronic paper cannot be directly exposed to the outermost layer and needs to be placed on the inside of the glass panel. In the embodiment of the present invention, the electronic paper 30 is fixed between the glass panel 250 of the door shell 210 and the door body liner 220. The electronic paper 30 is fixed to the glass panel 250 by optical glue. The fixed electronic paper 30 and the glass panel 250 are first glued to the door frame with glue. After that, after covering the door body liner 220, a foaming agent is injected into the door body. As the foaming agent expands, the foaming agent will stick to the electronic paper. In addition, the glass panel that is not covered by the electronic paper can directly contact the foaming agent, thereby achieving the effect of using the foaming agent to fix the glass panel, the door body liner and the electronic paper. Since the glass panel needs to reserve a contact area with the foaming agent around it, and this part does not fit the electronic paper, the size of the electronic paper 30 needs to be smaller than the size of the glass panel 250. The area of ​​the glass panel 250 not fitted with the electronic paper 30 needs to be silk-screened with the same color as the base color of the electronic paper 30, and the pattern and effect design of the entire electronic paper is integrated with the glass panel silk-screening, thereby solving the problem that the entire electronic paper cannot be installed and fixed on the refrigerator panel. Preferably, the effect design of the electronic paper pattern is carried out according to the size of all glass panels of the refrigerator door. The pattern of the electronic paper is partially fitted on each glass panel. The size of the electronic paper on each door is required to be smaller than the size of the glass panel, and each piece of electronic paper has a uniform base color that remains unchanged, while the pattern effect produced on the electronic paper can change color. The part of the glass panel that fits the electronic paper is made transparent to show the pattern and base color of the electronic paper. The other parts that are not fitted with the electronic paper are silk-screened with the same color as the base color of the electronic paper, so that the overall appearance effect of the glass panel and the electronic paper is integrated.

[0070] The embodiment of the present invention can retain the original design of stabilizing the refrigerator glass panel by using a foaming agent, and can also achieve the effect of installing and bonding the electronic paper on the refrigerator glass panel.

[0071] As one of the optional embodiments, a pattern is printed on the electronic paper, and the controller is further configured to:

[0072] The output voltages at different positions of the pattern on the electronic paper are controlled so that different positions of the pattern on the electronic paper display different colors.

[0073] As one of the optional embodiments, the electronic paper is printed with pattern code segments of different weather or festivals, and the controller is further configured to:

[0074] Weather information or holiday information is obtained from the cloud, and the output voltage of the electronic paper is controlled according to the weather information or the holiday information, so that the corresponding pattern on the electronic paper displays a color corresponding to the weather information or the holiday information.

[0075] For details, please refer to Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of a pattern effect of an electronic paper in a refrigerator provided by an embodiment of the present invention. Figure 8 This is a structural block diagram of a refrigerator provided by an embodiment of the present invention. In the embodiment of the present invention, the refrigerator eliminates the dedicated display panel and is configured with a main control panel and a WIFI module 50. The WIFI module 50 is interconnected with the mobile phone terminal through the cloud. In the embodiment of the present invention, a pattern is printed on the electronic paper. Different code segments can be preset in advance for control at different positions in the pattern. The controller can control the output voltage at different positions of the pattern on the electronic paper, so that different positions of the pattern on the electronic paper display different colors. In addition, in the embodiment of the present invention, pattern code segments for different weather or festivals can also be printed on the electronic paper, such as sunny, cloudy, rainy, etc. When the weather does not need to be displayed, the color of the pattern is consistent with the basic background color, and only the printed edge of the pattern can be seen. The WIFI module can obtain weather information or festival information from the cloud. The controller obtains weather information or festival information from the cloud through the WIFI module, and controls the output voltage of the electronic paper according to the weather information or festival information, so that the corresponding pattern on the electronic paper displays the color corresponding to the weather information or festival information. For example, when the weather needs to be displayed, the cloud obtains and analyzes that the weather is sunny, and the main control board outputs a control voltage signal to control the pattern of the sunny part to appear in different colors, highlighting the sunny weather, thereby adapting to the user's different moods and improving the intelligent experience of the refrigerator.

[0076] As one of the optional embodiments, the refrigerator further includes a voice module 60, and the voice module 60 is connected to the controller 40, and the controller 40 is further configured as follows:

[0077] Acquire voice instructions through the voice module 60, and obtain corresponding color instructions according to the voice instructions;

[0078] The output voltage of the electronic paper 30 is controlled according to the color instruction, so that the electronic paper 30 displays a color corresponding to the voice instruction.

[0079] Specifically, the refrigerator in this embodiment of the present invention further includes a voice module 60 for voice control. The voice module 60 is connected to the controller 40. The voice module 60 receives the user's voice command and parses the voice command to obtain a corresponding color command. The controller then controls the output voltage of the electronic paper 30 based on the color command, causing the electronic paper 30 to display the color corresponding to the voice command, thereby achieving the effect of voice-controlled refrigerator panel color adjustment.

[0080] It should be noted that, in the embodiment of the present invention, the controller may also directly receive a color instruction sent by the mobile terminal, and directly control the output voltage of the electronic paper according to the color instruction, so that the electronic paper displays the color corresponding to the color instruction. Figure 9 , Figure 9 This is a schematic diagram of the control interface of a mobile terminal in a refrigerator, provided by one embodiment of the present invention. The mobile phone presets the colors that the electronic paper can display. After the user selects a color and confirms it on the mobile phone, the mobile phone sends the protocol instruction corresponding to that color to the refrigerator's Wi-Fi module via the cloud via a preset communication protocol. The refrigerator's Wi-Fi module then sends the instruction to the refrigerator controller, which then outputs the voltage value corresponding to that color to the electronic paper. For example, the voltage value corresponding to white is 3.3V. This allows the color change of the electronic paper pattern to be controlled via a mobile phone app. Furthermore, the user can adjust the color of the panel pattern by taking a photo to identify it as needed, adapting it to different home environments. Different colors and icons can also be displayed based on different weather conditions and holidays, effectively enhancing the refrigerator's intelligence.

[0083] S2, determining a target color of the electronic paper according to the candidate colors and a preset color of the electronic paper;

[0084] S3, controlling the output voltage of the electronic paper according to the target color, so that the electronic paper displays a corresponding color.

[0085] In this embodiment of the present invention, electronic paper is mounted on the door housing outside the refrigerator, and its electrodes are connected to a controller. The electronic paper supports voltage modulation based on a base color to display different colors. The color-changing electronic paper works by applying different voltages to the electronic paper, causing the differently colored capsule particles within the paper to move and combine, resulting in the appearance of different colors. Therefore, after adding electronic paper to the refrigerator panel, the electronic paper's electrodes are connected to the controller. The controller transmits different voltages to the electronic paper, controlling the color change of the electronic paper's patterned portion while maintaining the base color. This achieves color change of the pattern on the refrigerator panel. The controller receives image data sent by a mobile terminal and uses an image recognition algorithm to perform color recognition on the image data, analyzing the color of the home cabinets or surrounding environment to obtain candidate colors. For example, a dominant color histogram method is used to calculate the proportion and probability of different colors in the entire image. The most frequently occurring color is selected as the dominant color of the image, i.e., the candidate color to be displayed by the electronic paper. The image data includes the refrigerator and its surroundings. Because e-paper comes with a preset set of supported colors, the target color of the e-paper is determined based on the candidate colors and the preset colors of the e-paper. For example, the characteristics of the identified primary color, such as RGB or HSV values, are compared with the characteristics of the colors supported by the e-paper. The color with the closest RGB or HSV value among the preset colors is recommended, which is the target color that the e-paper can display. Based on the target color, the electrode of the e-paper is controlled to output a voltage corresponding to the target color, causing the e-paper to display the corresponding color, achieving color change of the pattern on the e-paper, so that the refrigerator displays a color effect similar to that of the home.

[0086] It should be noted that the mobile terminal in the embodiment of the present invention includes but is not limited to mobile phones and tablets. In view of the trend of home integration, after placing the refrigerator and the home together, the mobile terminal can be used to take a picture of the overall effect of the refrigerator and the home around the refrigerator, and the picture can be sent to the controller, so as to achieve a color change effect according to the user's home style. In addition, in the embodiment of the present invention, the mobile terminal can also perform color recognition on the image data to obtain candidate colors. According to the candidate colors and the preset colors of the electronic paper set on the mobile terminal, the target color of the electronic paper is determined, and the user is prompted to modify the refrigerator pattern to the corresponding color through system comparison. After the user confirms, the mobile terminal sends the corresponding color instruction of the selected target color to the controller. The controller receives the color instruction and drives the voltage value of the color and sends it to the electrode end of the electronic paper, so that the electronic paper is refreshed to the corresponding color, so that the refrigerator panel shows an effect close to the color of the home environment.

[0087] The embodiment of the present invention controls the color change of the refrigerator panel by adding color-changing electronic paper to the outer shell of the refrigerator door. It has low cost and low power consumption, and can change the panel color according to the refrigerator environment, effectively improving user experience and refrigerator intelligence.

[0088] As one of the optional embodiments, the electronic paper is fixed between the glass panel of the door body shell and the door body liner, and the electronic paper is fixed to the glass panel by optical glue. After being fixed, the electronic paper, the glass panel and the door body liner are foamed; wherein, the size of the electronic paper is smaller than the size of the glass panel, and the area of ​​the glass panel not adhered to the electronic paper is silk-screened with the same color as the background color of the electronic paper.

[0089] Specifically, in order to realize that the color-changing characteristics of the electronic paper can be displayed on the panel, it is necessary to pass through the glass panel on the refrigerator. However, if the electronic paper is placed on the outside of the existing refrigerator glass panel, the electronic paper needs to be waterproof and moisture-proofed. Therefore, the electronic paper cannot be directly exposed on the outermost layer and needs to be placed on the inside of the glass panel. In the embodiment of the present invention, the electronic paper is fixed between the glass panel of the door shell and the door body. The electronic paper is fixed to the glass surface by optical glue. After the electronic paper and the glass panel are fixed, they are first glued to the door frame with glue. After that, after covering the door body, a foaming agent is injected into the door body. As the foaming agent expands, the foaming agent will stick to the electronic paper. In addition, the glass panel that is not covered by the electronic paper can directly contact the foaming agent, thereby achieving the purpose of using the foaming agent to fix the glass panel, the door body and the electronic paper. Because the glass panel needs to have a contact area with the foaming agent around it, and this area does not fit the e-paper, the size of the e-paper needs to be smaller than the size of the glass panel. The area of ​​the glass panel not fitted with the e-paper needs to be silk-screened with the same color as the e-paper's base color. The entire e-paper pattern and effects are designed to be integrated with the glass panel silk-screened to create a unified effect. This solves the problem of the e-paper being unable to be installed and fixed to the refrigerator panel. Preferably, the e-paper pattern effect is designed based on the size of all glass panels of the refrigerator door. Each glass panel partially fits the e-paper pattern. The e-paper size on each door is required to be smaller than the glass panel size, and each piece of e-paper has a uniform base color that remains unchanged, while the pattern effect created on the e-paper can change color. The part of the glass panel that fits the e-paper is made transparent to show the pattern and base color of the e-paper. The other parts not fitted with the e-paper are silk-screened with a color that matches the base color of the e-paper, so that the overall appearance of the glass panel and e-paper is integrated.

[0090] The embodiment of the present invention can retain the original design of stabilizing the refrigerator glass panel by using a foaming agent, and can also achieve the effect of installing and bonding the electronic paper on the refrigerator glass panel.

[0091] As one of the optional embodiments, a pattern is printed on the electronic paper, and the method further includes:

[0092] The output voltages at different positions of the pattern on the electronic paper are controlled so that different positions of the pattern on the electronic paper display different colors.

[0093] As one of the optional embodiments, the electronic paper is printed with pattern code segments of different weather or festivals, and the method further includes:

[0094] Weather information or holiday information is obtained from the cloud, and the output voltage of the electronic paper is controlled according to the weather information or the holiday information, so that the corresponding pattern on the electronic paper displays a color corresponding to the weather information or the holiday information.

[0095] Specifically, in the embodiment of the present invention, the refrigerator eliminates the dedicated display panel and is equipped with a main control panel and a WIFI module. The WIFI module is interconnected with the mobile phone via the cloud. In the embodiment of the present invention, a pattern is printed on the electronic paper. Different code segments can be preset in advance for control at different positions in the pattern. The controller can control the output voltage of different positions of the pattern on the electronic paper, so that different positions of the pattern on the electronic paper display different colors. In addition, in the embodiment of the present invention, pattern code segments for different weather or festivals can also be printed on the electronic paper. For example, sunny, cloudy, rainy, etc., when the weather does not need to be displayed, the color of the pattern is consistent with the basic background color, and only the printed edge of the pattern can be seen. The WIFI module can obtain weather information or festival information from the cloud. The controller obtains weather information or festival information from the cloud through the WIFI module, and controls the output voltage of the electronic paper according to the weather information or festival information, so that the corresponding pattern on the electronic paper displays the color corresponding to the weather information or festival information. For example, when the weather needs to be displayed, the cloud obtains and analyzes that the weather is sunny, and the main control board outputs a control voltage signal to control the pattern of the sunny part to appear in different colors, highlighting the sunny weather, thereby adapting to the user's different moods and improving the intelligent experience of the refrigerator.

[0096] As one of the optional embodiments, the refrigerator further includes a voice module, and the voice module is connected to the controller, and the method further includes:

[0097] Acquire voice commands through the voice module, and parse the voice commands to obtain corresponding color commands;

[0098] The output voltage of the electronic paper is controlled according to the color instruction so that the electronic paper displays a color corresponding to the voice instruction.

[0099] Specifically, the refrigerator in this embodiment of the present invention also includes a voice module that enables voice control. The voice module is connected to a controller. The voice module receives the user's voice command and interprets the voice command to obtain a corresponding color command. The controller controls the output voltage of the electronic paper based on the color command, causing the electronic paper to display the color corresponding to the voice command, thereby achieving the effect of voice-controlled refrigerator panel color adjustment.

[0100] It should be noted that, in the embodiment of the present invention, the controller can also directly receive a color instruction sent by the mobile terminal, and directly control the output voltage of the electronic paper according to the color instruction, so that the electronic paper displays the color corresponding to the color instruction. For example, the mobile phone presets the colors that the electronic paper can support. After the user selects a certain color and confirms it on the mobile phone, the mobile phone sends the protocol instruction corresponding to the color to the refrigerator WIFI module through the cloud through a preset communication protocol. After the refrigerator WIFI module receives the instruction, it sends it to the refrigerator controller. After receiving the instruction, the refrigerator controller outputs the voltage value corresponding to the color to the electronic paper. For example, the voltage value corresponding to white is 3.3v, thereby realizing the control of the color change of the electronic paper pattern through the mobile phone APP. In addition, the user can also take pictures to identify and adjust the color of the panel pattern as needed to adapt to different home environments, and support the display of different colors and different icons according to different weather / holidays, effectively improving the intelligence of the refrigerator.

[0101] An embodiment of the present invention provides a refrigerator and a display control method thereof. The method comprises adding color-changing electronic paper to the refrigerator door housing, with the electronic paper's electrode lines connected to a controller. The controller acquires image data sent by a mobile terminal and performs color recognition on the image data to obtain candidate colors, wherein the image data includes the refrigerator and its surroundings. The target color of the electronic paper is determined based on the candidate colors and a preset color of the electronic paper. The output voltage of the electronic paper is controlled based on the target color, causing the electronic paper to display the corresponding color. The embodiment of the present invention achieves color control of the refrigerator panel by adding color-changing electronic paper to the refrigerator door housing. This method is low-cost and consumes little power. Furthermore, the panel color can be changed according to the refrigerator environment, effectively improving the user experience and enhancing the refrigerator's intelligence.
