[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0046] In refrigerators, the duct light, or light located at the air vent, is often used as a decorative light, neglecting the deeper experiential benefits that lighting can provide to users. Furthermore, the shelf life of food in the refrigerator compartment is shorter than in the freezer compartment. To extend this time, sterilization components are usually installed in the refrigerator compartment to remove bacteria and other microorganisms from food, inhibiting or slowing down bacterial growth and spoilage. However, in these technologies, users cannot directly observe the sterilization process, leading to a decreased user experience.

[0047] To reduce the occurrence of the above situations, this application provides a refrigerator and its control method, control device and storage medium, which will be described below with reference to the accompanying drawings.

[0048] For example, the refrigerator includes a refrigerator compartment and a light strip and a sterilization component disposed within the refrigerator compartment. The refrigerator compartment is used to store food for short-term use. The refrigeration system delivers cold air into the refrigerator compartment through a refrigeration duct to maintain the temperature inside the refrigerator compartment at a preset temperature, such as 0℃-6℃, thereby preserving the food for short-term use. The light strip is disposed within the refrigerator compartment, and its specific location can be set as needed and is not limited here. The light strip can be used for decoration and lighting within the refrigerator compartment. In this embodiment, the light strip can also be used to display information such as the freshness of the food and the sterilization effect of the sterilization component. The sterilization component is used to sterilize the refrigerator compartment to inhibit or slow down bacterial growth, thereby extending the shelf life of the food. For example, the refrigerator compartment is provided with a refrigeration duct outlet, such as the outlet being located at the top of the refrigerator compartment. The sterilization component can be disposed within the refrigerator compartment at the corresponding outlet, so that the sterilizing substances released by the sterilization component can participate in the refrigeration cycle, thereby improving the uniformity of sterilization by the sterilization component.

[0049] It should be noted that, due to the diverse range of food items in the refrigerator compartment, different sterilization modules can be configured within the sterilization components to enhance their sterilization capabilities. These different modules correspond to different sterilization types. Furthermore, different sterilization components can be configured for different refrigerators, each corresponding to a different sterilization type. This application's embodiment uses the example of a refrigerator compartment sterilization component with different sterilization modules, each corresponding to a different sterilization type, for illustration.

[0050] Please see Figure 1 , Figure 1 This is a first flowchart illustrating a refrigerator control method provided in an embodiment of this application. An embodiment of this application provides a refrigerator control method, including:

[0051] 101. Obtain the sterilization type of the sterilization component.

[0052] The sterilization component may include multiple sterilization modules, at least two of which may have different sterilization types. Multiple sterilization modules can be installed in the same refrigerator, or different sterilization modules can be installed in different refrigerators.

[0053] Sterilization types can include ultraviolet sterilization, negative ion sterilization, ultra-high pressure sterilization, microwave sterilization, ozone sterilization, magnetic sterilization, high-voltage electric field sterilization, ultrasonic sterilization, and pulsed light sterilization. This application's embodiments use ultraviolet sterilization and negative ion sterilization as examples for illustration, and should not be construed as limiting the types of sterilization.

[0054] Ultraviolet (UV) sterilization utilizes UV wavelengths in the 240-280 nm range, which are most effective at destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, causing cell death and / or regenerative cell death, thus achieving sterilization and disinfection. The sterilization effect is strongest at a wavelength of 253.7 nm. The sterilization module corresponding to UV sterilization can be a UV lamp. Negative ion sterilization uses negative oxygen ions for sterilization. Negative oxygen ions carry excess electrons, which can kill bacteria and viruses by disrupting the molecular protein structure of microorganisms such as bacteria and viruses, causing structural changes or energy transfer, thereby leading to the death of bacteria, viruses, and other microorganisms. The sterilization module corresponding to negative ion sterilization can be a negative ion generator, which releases negative ions into the air. Therefore, the sterilization component in this embodiment can include a UV lamp and a negative ion generator. The negative ion generator can be placed at the air outlet of the refrigerated air duct so that the released negative ions can circulate with the airflow, improving the uniformity of sterilization. The ultraviolet lamp can be installed together with the negative ion generator at the air outlet of the refrigeration duct to facilitate the arrangement of wiring.

[0055] The sterilization type of a sterilization component can be determined by: retrieving the sterilization module of the sterilization component from the refrigerator's control program, and then determining the sterilization type based on the sterilization module. For example, the refrigerator's control program may store information about a corresponding negative ion generator, such as controlling the generator's activation time, duration, and concentration. The sterilization type can then be determined as negative ion sterilization based on the negative ion generator's information. Similarly, the refrigerator's control program may store information about a corresponding ultraviolet (UV) lamp, such as controlling the timing and duration of UV lamp irradiation. The sterilization type can then be determined as UV sterilization based on the UV lamp's information.

[0056] The sterilization type of the sterilization component can also be determined by a detection component. For example, a detection component can be installed in the cold storage room. If the detection component detects negative ions and / or ultraviolet light in the cold storage room, the sterilization type can be determined to be negative ion sterilization and / or ultraviolet sterilization.

[0057] 102. Determine the display method of the light strip according to the sterilization type.

[0058] Different light strip display methods can be configured for different sterilization types to distinguish between them. This allows users to intuitively see the sterilization status of each type and understand the freshness of the food based on the sterilization status. This helps users to handle the food in a timely manner and avoid waste caused by food spoilage.

[0059] Understandably, different sterilization methods have different sterilization speeds. For example, ultraviolet (UV) sterilization kills bacteria quickly because it involves direct irradiation. Negative ion sterilization, on the other hand, requires negative ions to react with substances in the food, and it takes time for the negative ions to reach the food. Therefore, negative ion sterilization is slower than UV sterilization. However, because UV sterilization covers a limited area and cannot reach all areas of a cold storage room, in practice, UV sterilization and negative ion sterilization are usually used in combination to improve the sterilization rate and effectiveness.

[0060] Therefore, different display methods can be configured for different types of sterilization. For example, for ultraviolet sterilization, which can quickly sterilize, a light display can be configured, showing things like light color and / or flashing frequency, which can intuitively reflect the sterilization status. On the other hand, for negative ion sterilization, which can sterilize evenly, a digital display can be configured, using changes in numbers to reflect the sterilization status and distinguishing it from ultraviolet sterilization. This allows users to understand the sterilization status of both types of sterilization simultaneously through color or numerical changes.

[0061] 103. Control the LED strip to display according to the display mode.

[0062] Once the display method for the sterilization type is determined, the light strip can be controlled to display the information according to this method, showing the user the sterilization status and allowing them to intuitively see the working status of the sterilization components, thus improving the user experience. For example, for ultraviolet sterilization, a light display method is used; correspondingly, when the light strip displays light, it can be confirmed that ultraviolet sterilization is being used, and the sterilization effect of the ultraviolet light can be determined based on the light display. As another example, for negative ion sterilization, a digital display method is used; correspondingly, when the light strip displays a number, it can be confirmed that negative ion sterilization is being used, and the sterilization effect of the negative ions can be determined based on the specific number displayed.

[0063] In existing technologies, LED strips are typically used for lighting or decoration, resulting in low utilization rates and easy overlooking by users. This application's embodiments, based on existing LED strips, configure them with different display methods, such as light displays and digital displays. Light displays include light color and flashing frequency, while digital displays show different numbers to represent sterilization rates. Reusing LED strips eliminates the need for additional display devices, saving space and improving the display effect, thus enhancing the user experience.

[0064] In the refrigerator control method provided in this application embodiment, the sterilization type of the sterilization component in the refrigerator compartment is displayed by light strip, that is, the sterilization status of the sterilization component is visualized. When the user puts in food, he / she can intuitively see the sterilization status of the sterilization component without having to wake up the display panel on the refrigerator door to check the sterilization status. This makes it convenient for the user to determine the freshness of the food in the refrigerator compartment based on the sterilization status, which can improve the user experience.

[0065] Please see Figure 2 As shown, Figure 2 This is a second flowchart illustrating the refrigerator control method provided in an embodiment of this application. An embodiment of this application also provides a refrigerator control method, including:

[0066] 201. Obtain the sterilization type of the sterilization component.

[0067] The sterilization component may include multiple sterilization modules, at least two of which may have different sterilization types. Multiple sterilization modules can be installed in the same refrigerator, or different sterilization modules can be installed in different refrigerators.

[0068] Sterilization types can include ultraviolet sterilization, negative ion sterilization, ultra-high pressure sterilization, microwave sterilization, ozone sterilization, magnetic sterilization, high-voltage electric field sterilization, ultrasonic sterilization, and pulsed light sterilization. This application's embodiments use ultraviolet sterilization and negative ion sterilization as examples for illustration, and should not be construed as limiting the types of sterilization.

[0069] Ultraviolet (UV) sterilization utilizes UV wavelengths in the 240-280 nm range, which are most effective at destroying the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in bacteria and viruses, causing cell death and / or regenerative cell death, thus achieving sterilization and disinfection. The sterilization effect is strongest at a wavelength of 253.7 nm. The sterilization module corresponding to UV sterilization can be a UV lamp. Negative ion sterilization uses negative oxygen ions for sterilization. Negative oxygen ions carry excess electrons, which can kill bacteria and viruses by disrupting the molecular protein structure of microorganisms such as bacteria and viruses, causing structural changes or energy transfer, thereby leading to the death of bacteria, viruses, and other microorganisms. The sterilization module corresponding to negative ion sterilization can be a negative ion generator, which releases negative ions into the air. Therefore, the sterilization component in this embodiment can include a UV lamp and a negative ion generator. The negative ion generator can be placed at the air outlet of the refrigerated air duct so that the released negative ions can circulate with the airflow, improving the uniformity of sterilization. The ultraviolet lamp can be installed together with the negative ion generator at the air outlet of the refrigeration duct to facilitate the arrangement of wiring.

[0070] The sterilization type of a sterilization component can be determined by: retrieving the sterilization module of the sterilization component from the refrigerator's control program, and then determining the sterilization type based on the sterilization module. For example, the refrigerator's control program may store information about a corresponding negative ion generator, such as controlling the generator's activation time, duration, and concentration. The sterilization type can then be determined as negative ion sterilization based on the negative ion generator's information. Similarly, the refrigerator's control program may store information about a corresponding ultraviolet (UV) lamp, such as controlling the timing and duration of UV lamp irradiation. The sterilization type can then be determined as UV sterilization based on the UV lamp's information.

[0071] The sterilization type of the sterilization component can also be determined by a detection component. For example, a detection component can be installed in the cold storage room. If the detection component detects negative ions and / or ultraviolet light in the cold storage room, the sterilization type can be determined to be negative ion sterilization and / or ultraviolet sterilization.

[0072] 202. If the sterilization type is ultraviolet sterilization, then the display mode of the light strip is determined to be light display.

[0073] Different types of sterilization have different sterilization speeds. For example, ultraviolet (UV) sterilization, because it kills germs directly through irradiation, is relatively fast. UV sterilization systems that can quickly kill germs often include lighting displays, such as light color and / or flashing frequency, which visually reflect the sterilization progress. Specifically, the brightness of the light color is positively correlated with the sterilization rate of UV sterilization; that is, the higher the sterilization rate, the brighter the corresponding light color. Similarly, the flashing frequency is also positively correlated with the sterilization rate; the higher the sterilization rate, the higher the flashing frequency.

[0074] The sterilization rate of ultraviolet (UV) sterilization can be determined by the light intensity of the UV lamp. Higher light intensity indicates a higher sterilization rate, while lower intensity indicates a lower sterilization rate. Different lighting display methods can be configured for the LED strip to achieve different sterilization rates.

[0075] For example, please refer to Table 1, which is a comparison table of UV sterilization rate and light display. Green, blue, and orange can be used to display the sterilization rate of UV sterilization. The brightness of green, blue, and orange increases sequentially, and the sterilization rate corresponding to each color increases sequentially. For instance, the UV sterilization rate can be represented by a number within the range of 1%-100%, which can be divided into three ranges, each corresponding to a different light color. For example, if the sterilization rate is in the range of 1%-30%, the light color is green. A green brightness level can also be set; the green brightness is positively correlated with the sterilization rate, meaning the higher the sterilization rate, the brighter the green. This can indirectly reflect that the food inside the refrigerator is in good condition, therefore the UV sterilization intensity is low, and the sterilization rate is low. As another example, if the sterilization rate is in the range of 30%-70%, the light color is blue. A blue brightness level can also be set; the blue brightness is positively correlated with the sterilization rate, meaning the higher the sterilization rate, the brighter the blue. Blue can also indirectly reflect that the food inside the refrigerator is in good condition. For example, when the sterilization rate is between 70% and 100%, the light color is orange. The brightness level of the orange can also be set; the brightness of the orange is positively correlated with the sterilization rate, meaning the higher the sterilization rate, the brighter the orange light. Orange can also indirectly indicate contamination of food inside the cold storage room.

[0076] Of course, the color display of the light strip is not limited to the three colors mentioned above; more colors can be used. The above is just an example of three colors and should not be interpreted as a limitation on the light display of the light strip.

[0077] It should be noted that the brightness levels of green, blue, and orange can be set as needed. The brightness levels that the light strip can display correspond to the settings mentioned above. Thus, the color of the light strip can indicate both the sterilization status of the ultraviolet light and the freshness of the food.

[0078] The LED strip can display the sterilization rate by showing only the light color, only the light flashing frequency, or both simultaneously. The flashing frequency is positively correlated with the UV sterilization rate; that is, the higher the sterilization rate, the higher the flashing frequency. For example, when the UV sterilization rate is in the range of 1%-30%, the flashing frequency can be 2 times per second. Another example is when the UV sterilization rate is in the range of 30%-70%, the flashing frequency can be 5 times per second. Yet another example is when the UV sterilization rate is in the range of 70%-100%, the flashing frequency can be 8 times per second. Displaying the LED strip at a preset flashing frequency creates a breathing light effect, enhancing the refrigerator's intelligent display.

[0079] Table 1 Comparison of UV sterilization rate and light display

[0080]

[0081] When using both light color and flashing frequency for the light strip, the light color and / or flashing can be displayed when the door is open, but not when the door is closed, in order to save energy consumption of the light strip.

[0082] 203. If the sterilization type is negative ion sterilization, then the display mode of the light strip should be digital display.

[0083] Different sterilization types have different sterilization speeds. Negative ion sterilization requires negative ions to react with substances in the food to kill germs, and it takes time for negative ions to travel into the food. Therefore, negative ion sterilization is slower than ultraviolet sterilization. Negative ion sterilization, which can sterilize evenly, is equipped with a digital display. Changes in the numbers reflect the sterilization progress and can be distinguished from ultraviolet sterilization, allowing users to understand the sterilization status of both methods simultaneously through color or numerical changes.

[0084] The sterilization rate of negative ion sterilization can be determined by the concentration of negative ions in the cold storage room. The higher the concentration of negative ions, the lower the survival rate of bacteria in the cold storage room, and therefore the higher the sterilization rate.

[0085] For example, if the sterilization type is negative ion sterilization, the display method of the light strip will be a digital display within the range of 0-100. The digital display is positively correlated with the sterilization rate of negative ion sterilization; that is, the higher the sterilization rate, the larger the displayed number. For example, the negative ion concentration can be divided into 100 levels, and the digital display of the light strip for each negative ion concentration can be a value within the range of 0-100. The size of the displayed number indicates the effectiveness of negative ion sterilization.

[0086] 204. Control the LED strip to display according to the display mode.

[0087] Once the display method for the sterilization type is determined, the light strip can be controlled to display the information according to this method, showing the user the sterilization status and allowing them to intuitively see the working status of the sterilization components, thus improving the user experience. For example, for ultraviolet sterilization, a light display method is used; correspondingly, when the light strip displays light, it can be confirmed that ultraviolet sterilization is being used, and the sterilization effect of the ultraviolet light can be determined based on the light display. As another example, for negative ion sterilization, a digital display method is used; correspondingly, when the light strip displays a number, it can be confirmed that negative ion sterilization is being used, and the sterilization effect of the negative ions can be determined based on the specific number displayed.

[0088] In existing technologies, LED strips are typically used for lighting or decoration, resulting in low utilization rates and easy overlooking by users. This application's embodiments, based on existing LED strips, configure them with different display methods, such as light displays and digital displays. Light displays include light color and flashing frequency, while digital displays show different numbers to represent sterilization rates. Reusing LED strips eliminates the need for additional display devices, saving space and improving the display effect, thus enhancing the user experience.

[0089] In the refrigerator control method provided in this application embodiment, the sterilization type of the sterilization component in the refrigerator compartment is displayed by light strip, that is, the sterilization status of the sterilization component is visualized. When the user puts in food, he / she can intuitively see the sterilization status of the sterilization component without having to wake up the display panel on the refrigerator door to check the sterilization status. This makes it convenient for the user to determine the freshness of the food in the refrigerator compartment based on the sterilization status, which can improve the user experience.

[0090] It should be noted that the sterilization rate of the aforementioned sterilization components can also be displayed simultaneously on the display panel on the refrigerator door. For example, when the refrigerator door is open, the user can check the sterilization status of the components while placing food inside. After the refrigerator door is closed, the user can check the sterilization status through the display panel on the door. This makes it convenient for users to check the sterilization status and improves user satisfaction.

[0091] Please see Figure 3 As shown, Figure 3 This is a third flowchart illustrating the refrigerator control method provided in this application embodiment. This application embodiment also provides a refrigerator control method, including:

[0092] 301. When the user puts in the food, control the sterilization component to perform ultraviolet sterilization.

[0093] When the user opens the refrigerator door and places food inside, they can control the sterilization component to use ultraviolet (UV) sterilization. Because UV sterilization is fast and direct, the UV lamp directly irradiates the food to inhibit bacterial growth. For example, the user can set a preset time to irradiate the food with the UV lamp when the door is opened. Simultaneously, the user can monitor the sterilization effect of negative ions on the existing food through the light strip.

[0094] The system first detects whether the door is open when a user places food inside. If the door is open, the corresponding light strip displays the sterilization process. Furthermore, when the door is open, the system controls the ultraviolet sterilization module of the sterilization component. Secondly, it uses image capture to determine if new food has been placed inside. If new food is placed inside, its position is detected, and the ultraviolet light is moved to that position to sterilize the food.

[0095] Whether a door is open can be determined by detecting the rotation of the door hinge. For example, detecting the rotation of the door hinge in a first direction indicates that the door is open; detecting the rotation of the door hinge in the opposite direction indicates that the door is closed. Furthermore, the angle of rotation of the door hinge can be used to determine whether the door is tightly closed.

[0096] 302. When the refrigerator door is detected to be closed, the sterilization components are controlled to stop ultraviolet sterilization.

[0097] The detection method for door closure can be the same as that for door opening. When the door is detected to be closed, the sterilization components can be controlled to stop ultraviolet sterilization. This is because the goal at this time is to eliminate bacteria throughout the entire refrigerator compartment, rather than targeting a specific area. Therefore, stopping ultraviolet sterilization can save power consumption of the sterilization components, thereby improving the refrigerator's energy efficiency.

[0098] 303. Control the sterilization components to perform negative ion sterilization.

[0099] After the door is closed, ultraviolet sterilization can be stopped, and negative ion sterilization can be used in a circulating manner.

[0100] For example, the freshness of the food in the cold storage room is obtained, and the concentration of negative ions released by the sterilization component is determined based on the freshness of the food. The freshness of the food is negatively correlated with the concentration of negative ions, and the concentration of negative ions is positively correlated with the digital display.

[0101] The freshness of ingredients can be represented by detecting the gas concentration in the cold storage room. For example, the freshness of ingredients can be determined by detecting the ammonia concentration in the cold storage room. Ammonia concentration and freshness are inversely correlated; that is, the higher the ammonia concentration, the lower the freshness of the ingredients. In some embodiments, a preset ammonia concentration can be set in the cold storage room, and the ratio of the detected ammonia concentration to the preset ammonia concentration can be used as the freshness of the ingredients. This allows for a visual representation of the freshness and facilitates correlation with negative ion concentration, simplifying program design and display.

[0102] In the refrigerator control method provided in this application embodiment, different sterilization methods are used for sterilization when the user opens the door to put food into the refrigerator and after the refrigerator door is closed. Ultraviolet sterilization can specifically sterilize the food, while negative ion sterilization can remove residual bacteria. The combination of the two sterilization methods can improve the sterilization effect on the one hand, and save the overall power consumption of the refrigerator on the other hand, thereby improving the overall energy utilization rate of the refrigerator.

[0103] To facilitate better implementation of the refrigerator control method of this application embodiment, this application embodiment also provides a refrigerator control device. Please refer to... Figure 4 , Figure 4This is a schematic diagram of the control device for a refrigerator provided in an embodiment of this application. The refrigerator control device 400 includes an acquisition unit 401, a determination unit 402, and a control unit 403. The refrigerator includes a refrigerator compartment and a light strip and a sterilization component disposed within the refrigerator compartment. The refrigerator compartment is used to store food for short-term use. The refrigeration system delivers cold air into the refrigerator compartment through a refrigeration duct to maintain the temperature within the refrigerator compartment at a preset temperature, such as 0℃-6℃, thereby preserving the food for short-term use. The light strip is disposed within the refrigerator compartment; its specific location can be set as needed and is not limited here. The light strip can be used for decoration and lighting within the refrigerator compartment. In this embodiment, the light strip can also be used to display information such as the freshness of the food and the sterilization effect of the sterilization component. The sterilization component is used to sterilize the refrigerator compartment to inhibit or slow down bacterial growth, thereby extending the shelf life of the food. For example, the cold storage room is equipped with cold storage air duct outlets. The outlets can be located at the top of the cold storage room, and the sterilization components can be installed in the cold storage room at the corresponding outlets. This allows the sterilizing substances released by the sterilization components to participate in the refrigeration cycle, thereby improving the uniformity of sterilization.

[0104] It should be noted that, due to the diverse range of food items in the refrigerator compartment, different sterilization modules can be configured within the sterilization components to enhance their sterilization capabilities. These different modules correspond to different sterilization types. Furthermore, different sterilization components can be configured for different refrigerators, each corresponding to a different sterilization type. This application's embodiment uses the example of a refrigerator compartment sterilization component with different sterilization modules, each corresponding to a different sterilization type, for illustration.

[0105] Of course, a refrigerator may also include other components such as a display panel, evaporator, compressor, etc., but no specific limitations are made here.

[0106] The acquisition unit 401 is used to acquire the sterilization type of the sterilization component.

[0107] The determining unit 402 is used to determine the display mode of the light strip according to the sterilization type.

[0108] Control unit 403 is used to control the light strip to display according to the display mode.

[0109] All of the above technical solutions can be combined in any way to form optional embodiments of this application, and will not be described in detail here.

[0110] As can be seen from the above, in the refrigerator control device 400 provided in this application embodiment, the sterilization type of the sterilization component in the refrigerator compartment is displayed by light strip, that is, the sterilization status of the sterilization component is visualized. When the user puts in the food, he / she can intuitively see the sterilization status of the sterilization component without having to wake up the display panel on the refrigerator door to check the sterilization status. This makes it convenient for the user to determine the freshness of the food in the refrigerator compartment based on the sterilization status, which can improve the user experience.

[0111] Accordingly, this application also provides a refrigerator, please refer to... Figures 1 to 4 And see Figure 5 and Figure 6 As shown, Figure 5 This is a schematic diagram of the structure of a refrigerator provided in an embodiment of this application. Figure 6 This is a schematic diagram of the structure of the refrigerator compartment provided in this embodiment. The refrigerator 500 includes a refrigerator compartment 501, and a light strip 502 and a sterilization component 503 disposed within the refrigerator compartment 501. The refrigerator compartment 501 is used to store food for short-term use. The refrigeration system delivers cold air into the refrigerator compartment 501 through a refrigeration duct to maintain the temperature within the refrigerator compartment 501 at a preset temperature, such as 0℃-6℃, thereby preserving the food for short-term use. The light strip 502 is disposed within the refrigerator compartment 501, and its specific location can be set as needed and is not limited here. The light strip 502 can be used for decoration and lighting within the refrigerator compartment 501. In this embodiment, the light strip 502 can also be used to display information such as the freshness of the food and the sterilization effect of the sterilization component 503. The sterilization component 503 is used to sterilize the refrigerator compartment 501 to inhibit or slow down bacterial growth, thereby extending the shelf life of the food. For example, the cold storage compartment 501 is equipped with a cold storage air duct outlet. The outlet can be located at the top of the cold storage compartment 501, and the sterilization component 503 can be located in the cold storage compartment at the corresponding outlet, so that the sterilization substance released by the sterilization component 503 can participate in the refrigeration cycle, thereby improving the uniformity of sterilization by the sterilization component.

[0112] It should be noted that, due to the diverse range of food items in the refrigerator compartment 501, different sterilization modules can be configured for the sterilization component 503 to enhance its sterilization capability. Different sterilization modules correspond to different sterilization types. Alternatively, different sterilization components 503 can be configured for different refrigerators 500, each corresponding to a different sterilization type. This embodiment of the application uses the example of a sterilization component 503 in the refrigerator compartment 501 having different sterilization modules, each corresponding to a different sterilization type, for illustration.
