For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.
[0050] Currently, when using medications, patients with diabetes, pneumonia, and other conditions typically place them in refrigerator drawers or shelves. However, the temperature distribution inside a refrigerator is uneven, and the humidity is also high, making it impossible to provide a stable temperature and humidity environment for the medications. This can easily affect the properties of the medications. Furthermore, when users need to take the medications out, there is usually a lack of effective insulation measures, which can cause the medications to become ineffective due to high external temperatures.
[0051] To address this issue, this application designs a medicine storage box 300 inside the refrigerator, creating an independent medicine storage environment. Components such as a fan 302, a cooling component 303, and a valve 400 precisely regulate the temperature and humidity within the medicine storage box 300, ensuring stable storage conditions for the medicines. Furthermore, the medicine storage box 300 is designed to be detachable. After being separated from the refrigerator, the built-in fan 302 and cooling component 303 can cool the medicines, maintaining a low temperature for a certain period, thus effectively solving the problem of medicine preservation when traveling.
[0052] In some embodiments, refer to Figures 1 to 9As shown, this application provides a refrigerator, including: a refrigerator liner 100, a refrigeration air duct 200, a medicine storage box 300, and a valve 400. The refrigerator liner 100 forms a refrigerator compartment 101; the refrigeration air duct 200 is located on the side of the refrigerator liner 100 facing away from the refrigerator compartment 101 and is connected to the refrigerator compartment 101; the medicine storage box 300 is detachably disposed within the refrigerator compartment 101, and includes a box body 301, a fan 302, and a refrigeration component 303. The box body 301 has an air inlet 304 for connecting to the refrigeration air duct 200, the fan 302 is located at the air inlet 304, and the refrigeration component 303 is disposed within the box body 301; the valve 400 is configured to open or close the flow path between the air inlet 304 and the refrigeration air duct 200.
[0053] The refrigerator liner 100 is the inner structure of the refrigerator used to create the refrigeration or freezing space. It is the part of the refrigerator that directly contacts the stored items and can be made of materials such as plastic or metal. The design of the liner 100 plays an important role in maintaining the internal temperature of the refrigerator, preventing cold air loss, and facilitating cleaning. Inside the liner 100, a refrigerator compartment 101 is formed for storing items that require low-temperature preservation, such as food or medicine. The refrigerator compartment 101 has an opening on the front for easy access to food or medicine.
[0054] The refrigeration air duct 200 is an important component inside the refrigerator, responsible for evenly distributing the cold air generated by the refrigerator's refrigeration system (not shown in the figure) into the refrigerator compartment 101. The refrigeration air duct 200 is located on the back of the refrigerator liner 100, hidden within the foam layer between the liner 100 and the refrigerator outer shell. Through this duct, cold air can be delivered to different areas of the refrigerator compartment 101, ensuring that the temperature distribution within the entire refrigerator compartment 101 is as uniform as possible. Specifically, when the medicine box 300 is placed inside the refrigerator compartment 101, the refrigeration air duct 200 can connect with the air inlet 304 of the medicine box 300, providing a cold source to the medicine box 300 and maintaining a suitable low-temperature environment for medicine storage, thereby achieving control over the medicine storage conditions.
[0055] The medicine storage box 300 is specifically designed to precisely control the temperature and humidity of the medicine storage environment, ensuring that the medicine maintains its efficacy both inside and outside the refrigerator. The box body 301 is the outer shell of the medicine storage box 300, forming a sealed space to store the medicine and prevent it from being directly exposed to or damaged by the outside environment. It can be made of materials with good thermal insulation properties, such as polystyrene foam, polyurethane foam, glass wool, or vacuum insulation panels, to reduce the influence of the external environment on the internal temperature.
[0056] Fan 302 is a device used to promote airflow, and it is installed at the air inlet 304 of the medicine storage box 300. When it is necessary to adjust the temperature inside the medicine storage box 300, fan 302 is activated to introduce cold air from the refrigerated air duct 200 into the box 301. Alternatively, when it is not necessary to introduce cold air from the refrigerated air duct 200, fan 302 circulates the air inside the box 301 for dehumidification or to maintain a stable temperature. This effectively controls the temperature and humidity inside the medicine storage box 300, ensuring the safety of medicine storage.
[0057] The refrigeration component 303 refers to a series of devices or components capable of generating cooling capacity and lowering the ambient temperature. Optionally, the refrigeration component 303 can be an ice pack 305, a cold storage agent 313, a semiconductor cooling chip, etc. After the medicine storage box 300 is removed from the refrigerator compartment 101, since it loses its connection with the refrigeration air duct 200, the built-in refrigeration component 303 can maintain a low-temperature environment, providing additional cooling capacity for the medicine storage box 300 and ensuring that the medicine remains under suitable low-temperature conditions even when carried out.
[0058] The main function of valve 400 is to open or close the connection between air inlet 304 and refrigerated air duct 200 as needed. When the medicine box 300 is placed in the refrigerator compartment 101 and the temperature inside the medicine box 300 is higher than the set value, valve 400 will open, allowing cold air from the refrigerated air duct 200 to flow into the medicine box 300 to lower the temperature. Once the desired temperature is reached, if the humidity is still high, valve 400 will close to prevent cold air from entering the refrigerated air duct 200, and dehumidification will be achieved through the air blown out by fan 302. By precisely controlling the state of valve 400, the temperature and humidity conditions inside the medicine box 300 can be effectively regulated, ensuring that the medicine is always in the optimal storage environment. Valve 400 can be operated mechanically or electronically, for example, by using control devices such as dampers or solenoid valves.
[0059] The working principle of the medicine storage box 300 provided in the embodiments of this application will be described below, which generally includes the environment in which the medicine storage box 300 is placed in the refrigerator compartment 101 and taken out of the refrigerator compartment 101 for use.
[0060] When the medicine storage box 300 is placed in the refrigerator compartment 101: the medicine storage box 300 is connected to the refrigerator air duct 200 through the air inlet 304, and the valve 400 and fan 302 are automatically adjusted according to the temperature and humidity inside the medicine storage box 300. Specifically, if the temperature is higher than the set value, the valve 400 opens and the fan 302 starts to introduce cold air from the refrigerator air duct 200 into the medicine storage box 300 for cooling; after the set temperature is reached, if the humidity is still high, the valve 400 is closed, and the humidity is reduced by the air blown out by the fan 302.
[0061] When the medicine storage box 300 is taken out of the refrigerator compartment 101 for use: After the medicine storage box 300 is separated from the refrigerator compartment 101, it becomes an independent unit. It is mainly cooled by the cooling component 303. Once the internal temperature is detected to rise above the set value, the fan 302 starts to work to maintain the low temperature environment inside the medicine storage box 300.
[0062] Therefore, the refrigerator provided in this application embodiment, by integrating a medicine storage box 300, can provide a storage environment for medicines that can be used both at home and outside, which can not only extend the shelf life of medicines, but also greatly improve the user's convenience and experience.
[0063] In some embodiments, refer to Figures 7 to 9 As shown, the refrigeration component 303 includes an ice pack 305; the box body 301 is provided with a first partition 306 to divide the internal space of the box body 301 into a refrigeration zone 307 and a medicine storage zone 308, and the first partition 306 is provided with a first flow hole 309. The ice pack 305 is placed in the refrigeration zone 307 and placed on the first partition 306. The refrigeration zone 307 is connected to the air inlet 304, and the medicine storage zone 308 is connected to the refrigeration zone 307 through the first flow hole 309.
[0064] The first partition 306 divides the internal space of the box 301 into two independent areas: the cooling zone 307 and the medicine storage zone 308. This design effectively isolates the cold source (such as ice packs 305) from the medicine, avoiding direct contact that could damage the medicine.
[0065] The first flow-through orifice 309 is located on the first partition 306, allowing air cooled by the ice pack 305 to flow from the refrigeration zone 307 into the drug storage zone 308. This method ensures that the drug receives uniform cooling, thereby guaranteeing the drug's quality. Optionally, there can be multiple first flow-through orifices 309, spaced apart to improve the cooling effect. The shape of the first flow-through orifice 309 is not particularly limited; for example, it can be strip-shaped, circular, rectangular, etc.
[0066] As an example, such as Figures 7 to 9As shown, the air inlet 304 can be located in the middle of the side of the box 301 along the width direction. The first partition 306 is approximately L-shaped and includes a vertical partition 310 and a horizontal partition 311. The vertical partition 310 and the horizontal partition 311 can be a separate connection structure or an integrally formed structure. The vertical partition 310 is vertically arranged along the height direction of the medicine storage box 300 and is spaced from the side of the box 301 where the air inlet 304 is located. The lower end of the vertical partition 310 extends to the air inlet 304, and the upper end of the vertical partition 310 is connected to one end of the horizontal partition 311. The horizontal partition 311 is horizontally arranged in the box 301 along the length direction of the medicine storage box 300 and is spaced from the top of the box 301. The other end of the horizontal partition 311 is connected to the side opposite the air inlet 304, thereby constructing a cooling zone 307 and a medicine storage zone 308 within the box 301. In addition, one or more limiting grooves 312 can be provided on the partition plate 311. The limiting grooves 312 are used to place and fix the ice pack 305, and the first flow hole 309 can be provided on the partition plate 311.
[0067] When the medicine box 300 is placed in the refrigerator compartment 101, the user can decide whether to place an ice pack 305 according to actual needs; while when the medicine box 300 is taken out and carried out, the ice pack 305 becomes the key to maintaining a low temperature environment. This method is both flexible and practical, and is especially suitable for situations where medicines are carried out for short periods of time.
[0068] For example, when the user is away from home, the medicine storage box 300 is placed in the external environment where the surrounding temperature is high. At this time, four ice packs 305 can be placed on the partition 311 of the medicine storage box 300. When the fan is running, it will guide air through the air inlet 304 into the cooling zone 307. Here, the air will be cooled by passing through the ice packs 305, and then enter the medicine storage zone 308 through the first flow hole 309, providing the medicine with the required low temperature environment. This can prevent the medicine from becoming ineffective due to the high outside temperature.
[0069] Therefore, this design in the embodiments of this application greatly improves the flexibility and adaptability of the medicine storage box 300, enabling it to work effectively not only in a home refrigerator environment but also to ensure the safe storage of medicines in non-fixed environments such as when traveling. For medicines requiring strict temperature control (such as insulin, vaccines, etc.), this design with an ice pack 305 for auxiliary cooling adds extra safety assurance while also improving user convenience and satisfaction.
[0070] In some embodiments, refer to Figure 8 and Figure 9As shown, the refrigeration assembly 303 also includes a cold storage agent 313; a second partition 314 is also provided inside the housing 301 to form a cold storage zone 315 inside the housing 301, and the cold storage agent 313 is disposed in the cold storage zone 315; a second flow hole is provided on the second partition 314, and the cold storage zone 315 is connected to the drug storage zone 308 through the second flow hole, or the second partition 314 is a heat-conducting component.
[0071] Cold storage agent 313 is a material that can absorb and store a large amount of cold energy at low temperatures and slowly release the cold energy as the temperature rises. Cold storage agent 313 may include some phase change materials (PCMs), such as certain types of paraffin or hydrated salts, which can undergo phase change (e.g., from solid to liquid) within a specific temperature range, thereby absorbing or releasing a large amount of latent heat.
[0072] By setting a second partition 314, a dedicated cold storage zone 315 can be formed within the housing 301 for storing the cold storage agent 313. This helps to separate the cold storage agent 313 from the medicine, preventing direct contact from affecting the medicine.
[0073] Optionally, the second partition 314 is provided with a second flow-through hole to allow the cold energy released by the refrigerant 313 to enter the drug storage compartment 308. Multiple second flow-through holes can be provided, spaced apart to improve the cooling effect. The shape of the second flow-through hole is not particularly limited; for example, it can be strip-shaped, circular, or rectangular. Optionally, the second partition 314 can be used as a heat-conducting component, and can be made of materials with good thermal conductivity, such as aluminum or copper, to facilitate the transfer of cold energy from the refrigerant 313 to the drug in the drug storage compartment 308 via heat conduction.
[0074] When operating inside the refrigerator: When the medicine storage box 300 is placed in the refrigerator compartment 101, the fan 302 starts and draws in cold air from the cold air duct 200 to cool the medicine storage box 300 and maintain a low-temperature environment. At the same time, the cold storage agent 313 begins to absorb and store cold energy. Due to its efficient energy storage characteristics, it can effectively reduce temperature fluctuations inside the medicine storage box 300, ensuring that the medicine is kept under suitable low-temperature conditions.
[0075] When taken out: When the medicine box 300 is taken out of the refrigerator compartment 101, the cold storage agent 313 gradually releases the cold energy absorbed before in the higher temperature of the outside, and transfers it to the medicine storage area 308 through the second flow hole or thermal conductivity, helping to maintain the low temperature environment of the medicine storage area 308.
[0076] Therefore, this design in the embodiments of this application not only improves the temperature control capability of the medicine storage box 300, but also enhances its adaptability to different environmental conditions.
[0077] In some embodiments, refer to Figure 9As shown, the refrigeration zone 307, the medicine storage zone 308, and the cold storage zone 315 are arranged sequentially from top to bottom along the height direction of the box 301.
[0078] The refrigeration zone 307, the drug storage zone 308, and the cold storage zone 315 are arranged in order of height, i.e., from top to bottom, they are the refrigeration zone (with built-in ice packs 305), the drug storage zone, and the cold storage zone (with built-in refrigerant 313). This vertically partitioned layout takes into account the sinking nature of cold air, making cooling more efficient. Specifically, the ice packs 305 placed at the top can utilize the principle of cold air sinking to flow directly downwards into the drug storage zone 308, achieving a rapid and uniform cooling effect. At the same time, the refrigerant 313 is located at the bottom of the drug storage zone 308, which can provide more comprehensive additional cooling support for the entire drug storage zone 308, stabilizing the temperature of the drug storage zone 308 and reducing temperature fluctuations.
[0079] Refrigerator operating mode: When the medicine storage box 300 is placed in the refrigerator compartment 101, the fan 302 starts and guides cold air through the air inlet 304 into the cooling zone 307. The cold air is first cooled by the ice pack 305, and then sinks into the medicine storage zone 308 through the first flow hole 309, providing the necessary low-temperature environment for the medicine. At the same time, the cold storage agent 313 begins to absorb and store a large amount of cold energy, which is slowly released when the temperature rises, helping to stabilize the temperature of the medicine storage zone 308 and reduce temperature fluctuations.
[0080] Outing mode: After the medicine storage box 300 leaves the refrigerator, the ice pack 305 gradually melts but still provides a certain cooling effect. At the same time, the cold storage agent 313 at the bottom begins to play its role, continuously releasing the previously stored cold energy to maintain the low temperature of the medicine storage compartment 308.
[0081] Therefore, by optimizing the distribution of each functional area, the embodiments of this application can significantly improve the overall cooling effect of the drug storage area 308 and reduce the risk of drug failure.
[0082] In some embodiments, refer to Figures 6 to 9 As shown, the housing 301 includes a cover plate 316, which is used to open or close the cooling compartment 307.
[0083] The housing 301 includes a cover 316, a frame 317, and a bottom plate 318. The cover 316 is connected to the top of the frame 317 via screws 319, clips, hinges, and other components. The air inlet 304, the first partition 306, and the second partition 314 are connected to the frame 317. A cooling zone 307 is formed between the cover 316 and the first partition 306. The bottom plate 318 is connected to the bottom of the frame 317 and forms a cold storage zone 315 between it and the second partition 314. The cover 316 is mainly used to close or open the cooling zone 307 to facilitate the placement or replacement of ice packs 305 by the user, and also to clean the cooling zone 307. This design not only protects the internal environment from external interference but also facilitates user operation. Optionally, a handle 320 can be provided on the cover 316 to greatly facilitate the user in lifting the medicine storage box 300 or opening the cover 316.
[0084] When the medicine storage box 300 is located in the refrigerator compartment 101, if the number of ice packs 305 needs to be adjusted according to the medicine storage requirements, the user can easily do so by opening the top cover 316. Before taking the medicine storage box 300 out, the user can pre-place an appropriate number of ice packs 305 according to the expected time of departure and the outside temperature conditions, and ensure that the cooling compartment 307 is well sealed by the cover 316 to maintain a low temperature environment.
[0085] Therefore, this design in the embodiments of this application takes into account the needs of users in actual operation, ensuring the functionality of the medicine storage box 300 while improving the convenience and comfort of use.
[0086] In some embodiments, refer to Figures 6 to 8 As shown, the box body 301 includes a side plate 321, which is used to open or close the medicine storage compartment 308.
[0087] Side panel 321 can be connected to the side of frame 317 along its length via screws, clips, hinges, pivots, etc., and is specifically used to open or close the medicine storage compartment 308, so that users can easily take out or put in medicines or clean the medicine storage compartment 308. Optionally, the upper side of side panel 321 is rotatably connected to frame 317 via pivot, and a button 322 can be provided on the lower side of side panel 321. The lower side of frame 317 is provided with a corresponding latch 323. When the user needs to open side panel 321, they can press button 322, and button 322 and latch 323 will unlock and separate. Conversely, when the user needs to close side panel 321, they can press side panel 321 until button 322 and latch 323 are locked. Alternatively, a first magnet can be provided on the lower side of side panel 321, and a metal part or second magnet corresponding to the first magnet is provided on the lower side of frame 317. The first magnet can be magnetically attracted to the metal part or second magnet. Furthermore, a handle can be installed on the side panel 321. The side panel 321 can be opened by overcoming the magnetic attraction through the handle. When closing, the side panel 321 can be rotated and closed under the action of magnetic attraction.
[0088] Therefore, the medicine storage box 300 with side panel 321 of this application not only enhances its practicality, but also improves the user's convenience in various situations, and is especially suitable for occasions where medicines need to be frequently stored and retrieved.
[0089] In some embodiments, refer to Figures 6 to 8 As shown, the frame 317 of the medicine storage box 300 is also provided with an air outlet 324 opposite to the air inlet 304.
[0090] An air inlet 304 is located on one side of the frame 317 to introduce cool air, while an air outlet 324 is located on the opposite side of the air inlet 304 to expel hot air or moisture. By guiding cool air in from one side and out from the other, effective air circulation within the entire medicine storage box 300 is promoted, reducing temperature differences and making the temperature in each area more uniform. When it is necessary to reduce humidity, the fan 302 can accelerate airflow, making it easier for moisture to be expelled from the medicine storage box 300 and keeping the internal environment dry.
[0091] In some embodiments, refer to Figures 7 to 9 As shown, at least one third partition 325 is provided in the drug storage area 308 to divide the drug storage area 308 into at least two drug storage sub-areas 326, and the third partition 325 is provided with a third flow hole 327, and each drug storage sub-area 326 is connected through the third flow hole 327.
[0092] A third partition 325 is disposed on the frame 317 of the medicine storage box 300, and is used to divide the medicine storage area 308 into multiple independent but interconnected medicine storage sub-areas 326. Each medicine storage sub-area 326 can be used to store different types or batches of medicines, realizing classified management. As an example, the medicine storage box 300 has a horizontally arranged third partition 325, which divides the medicine storage area 308 of the medicine storage box 300 into upper and lower medicine storage sub-areas 326.
[0093] A third flow-through hole 327 located on the third partition 325 allows cold air to flow between the various drug storage sub-sections 326, ensuring uniform temperature distribution throughout the entire drug storage section 308. Multiple third flow-through holes 327 can be provided, spaced apart to improve cooling efficiency. The shape of the third flow-through hole 327 is not particularly limited; for example, it can be strip-shaped, circular, or rectangular.
[0094] Therefore, this partitioned drug storage design can not only achieve classified storage of drugs, but also maintain the uniformity of internal temperature of the drug storage box 300.
[0095] In some embodiments, refer to Figures 7 to 9 As shown, the medicine storage box 300 also includes a sensor, which is located inside the box body 301 and is used to detect the temperature and humidity inside the box body 301.
[0096] The sensor can be an integrated temperature and humidity sensor, capable of simultaneously measuring and reporting temperature and humidity information. This simplifies hardware design and reduces installation space requirements. Alternatively, the sensor can include two independent temperature sensors 328 and humidity sensors 329. For example, the temperature sensor 328 can be a thermistor, thermocouple, etc., and the humidity sensor 329 can be a capacitive humidity sensor. Optionally, the sensor can be placed in the storage compartment 308 of the medicine storage box 300 to accurately reflect the actual temperature and humidity conditions of the medicine stored throughout the entire box 301.
[0097] In some embodiments, the medicine storage box 300 further includes a prompt (not shown) disposed on the box body 301.
[0098] The alert can be an audible alarm, an LED indicator, a display screen, or other form of notification device. The alert can be installed in a prominent external location on the medicine box 300 to ensure that the user can easily see or hear the alert. For example, it can be located on the side of the box body 301.
[0099] When the temperature inside the medicine dispenser 300 exceeds the set value, an alert will be activated to notify the user via sound, light, or other means. This immediate feedback mechanism helps to quickly take corrective measures, such as checking the status of the refrigeration unit 303, adjusting environmental conditions, or putting the medicine dispenser 300 back into the refrigerator as soon as possible.
[0100] Once the medicine box 300 is removed from the refrigerator compartment 101, the indicator will also signal to remind the user to check the current temperature and add ice packs 305 as needed to maintain a low temperature. For users planning to take medication out, this alert helps them prepare in advance, ensuring the medication remains within a safe temperature range throughout the trip.
[0101] Therefore, by integrating a prompter, this application not only enhances the intelligence level of the medicine storage box 300, but also significantly improves the user experience and the safety of medicine storage.
[0102] In some embodiments, the medicine storage box 300 may also include a controller (not shown) and a power supply (not shown).
[0103] The controller is the control unit of the entire medicine storage box 300. It is responsible for receiving data from sensors (such as temperature and humidity) and controlling the working status of other components according to preset logic. For example, it can start or stop the fan, adjust the valve (when the valve 400 is located at the air inlet 304) opening and closing, activate or deactivate the indicator, etc., thereby controlling the internal environment of the medicine storage box 300 and reducing the risk of medicine deterioration.
[0104] The power source can be a rechargeable battery, which can provide power to components such as the fan 302, sensors, controllers, and indicators without an external power source.
[0105] Therefore, the embodiments of this application efficiently integrate the controller, power supply and other components together, which can maximize the use of space while maintaining the portability and ease of use of the device.
[0106] In some embodiments, refer to Figures 1 to 5 As shown, the inner liner 100 is provided with a corresponding interface (not shown in the figure) for the air inlet 304. The refrigerated air duct 200 includes a first air duct 201 and a second air duct 202. The first air duct 201 is connected to the refrigerated compartment 101. One end of the second air duct 202 is connected to the first air duct 201 via a valve 400, and the other end of the second air duct 202 is connected to the interface.
[0107] The inner box 100 is equipped with a dedicated interface, which corresponds to the air inlet 304 on the medicine storage box 300. When the medicine storage box 300 is placed in the refrigerator compartment 101, the air inlet 304 of the medicine storage box 300 connects with the interface on the inner box 100 to form a closed air circulation path.
[0108] The first air duct 201 is used to deliver cold air generated by the refrigerator's refrigeration system into the refrigerator compartment 101. As an example, one end of the first air duct 201 can be connected to the refrigerator's refrigeration system, and the other end can be connected to the refrigerator compartment 101. A valve 400 is located in the first air duct 201. One end of the second air duct 202 is connected to the first air duct 201 via the valve 400. The flow paths of the first air duct 201 and the second air duct 202 can be controlled separately via valves (such as a three-way valve). In other examples, the valve 400 can also be located at the air inlet 304 of the medicine box 300 to control the flow path of the second air duct 202. This design allows a portion of the cold air diverted from the first air duct 201 to be directly supplied to the medicine box 300 via the second air duct 202 without affecting the overall cooling effect of the refrigerator compartment 101, ensuring that the medicine box 300 and the refrigerator compartment 101 receive independent cold air supplies.
[0109] In some embodiments, refer to Figures 1 to 3 As shown, the refrigerator also includes a door liner 500, which is connected to one side of the refrigerator liner 100 and is used to open or close the refrigerator compartment 101; and the refrigerator liner 100 has a slot structure on the inner wall adjacent to the refrigerator compartment 101, and / or the door liner 500 has a slot structure on the inner wall adjacent to the refrigerator compartment 101, the slot structure being used to hold the medicine box 300.
[0110] The door liner 500 is the part inside the refrigerator door, used to install shelves or other storage devices. It is hinged to one side of the liner 100 and can be opened or closed by opening and closing the refrigerator compartment 101.
[0111] The slot structure can be set on the inner wall of the box liner 100, allowing the medicine box 300 to be directly embedded therein, ensuring its stability and not affecting the storage of other items. Similarly, a slot structure can also be set on the inner wall of the door liner 500 to facilitate the quick loading and unloading of the medicine box 300.
[0112] Understandably, by utilizing the inner wall space of the cabinet liner 100 or the door liner 500, the main storage area inside the refrigerator can be avoided, allowing for more efficient use of the limited space.
[0113] As an example, the medicine box 300 is located in a slot structure on the inner wall of the door liner 500. An air inlet 304 is located on the side of the medicine box 300 adjacent to the hinge side of the door liner 500, and a corresponding interface is located on the side of the refrigerator liner 100 adjacent to the hinge side of the door liner 500. When the medicine box 300 is located on the door liner 500, the user can easily remove and place the medicine box 300 while opening the door, without needing to go deep into the refrigerator, greatly improving ease of use.
[0114] In some embodiments, refer to Figure 10As shown, this application also provides a refrigerator control method, which mainly includes the following steps.
[0115] S1001. Obtain the location information of the medicine storage box 300.
[0116] The location of the medicine box 300 can be determined by setting a position detection device in the card slot structure or installing a camera in the refrigerator compartment 101, and the result can be displayed on the refrigerator display panel.
[0117] S1002. Determine that the medicine storage box 300 is in the refrigerator compartment 101, obtain the temperature inside the medicine storage box 300, and when the temperature inside the medicine storage box 300 is greater than the first set value, control valve 400 opens the flow path between air inlet 304 and refrigerator air duct 200, and fan 302 starts running until the temperature inside the medicine storage box 300 is less than or equal to the first set value.
[0118] When the medicine storage box 300 is detected to be inside the refrigerator compartment 101, the sensor detects the temperature inside the medicine storage box 300. If the temperature exceeds the first set value (e.g., 5°C), the valve 400 is opened to connect the air inlet 304 with the refrigerator air duct 200, and the fan 302 is started to introduce cold air from the refrigerator air duct 200 into the medicine storage box 300 for cooling. After the fan 302 has been running for a period of time (e.g., 60 minutes), it is determined whether the temperature inside the box meets the design requirements. If it does not meet the requirements, the fan 302 continues to run for cooling until the temperature drops to equal to or below the first set value.
[0119] S1003. Determine that the medicine storage box 300 is outside the refrigerator compartment 101, obtain the temperature inside the medicine storage box 300, and when the temperature inside the medicine storage box 300 is greater than the second set value, control the fan 302 to start running for a preset time, obtain the temperature inside the medicine storage box 300 again, and when the temperature inside the medicine storage box 300 is greater than the third set value, prompt the user to check the refrigeration component 303 or put the medicine storage box 300 back into the refrigerator compartment 101.
[0120] When the medicine storage box 300 is detected to be outside the refrigerator compartment 101, the user is prompted to check the status of the ice pack 305 and the cold storage agent 313. At this time, the medicine storage box 300 relies on the built-in ice pack 305 and cold storage agent 313 to maintain a low-temperature environment. The temperature inside the medicine storage box 300 is continuously monitored by sensors. When the temperature exceeds a second set value (e.g., 10°C), the fan 302 starts operating to utilize existing cooling capacity for cooling. Since the cooling capacity provided by the ice pack 305 and cold storage agent 313 is limited, the temperature is checked again after the fan 302 has run for a certain period (e.g., 120 minutes). If the temperature is higher than a third set value (e.g., 30°C), it indicates that the temperature inside the box is too high, and an alert is issued so that the user can check the effectiveness of the ice pack 305 and cold storage agent 313 or quickly return the medicine storage box 300 to the refrigerator compartment 101 to avoid the high temperature affecting the quality of the medicine.
[0121] Therefore, the control method provided in this application embodiment can ensure that the medicine storage box 300 maintains suitable temperature conditions whether it is in a refrigerator or when it is carried out, thereby ensuring the quality and safety of the medicine.
[0122] In some embodiments, refer to Figure 10 As shown, the refrigerator control method of this application further includes the following steps:
[0123] S1004. When the temperature inside the medicine storage box 300 is less than or equal to the first set value, the humidity inside the medicine storage box 300 continues to be acquired. When the humidity inside the medicine storage box 300 is greater than the fourth set value, the control valve 400 shuts off the flow path between the air inlet 304 and the refrigerated air duct 200, and the fan 302 continues to run until the humidity inside the medicine storage box 300 is less than or equal to the fourth set value.
[0124] Initial temperature control stage: When the medicine storage box 300 is placed in the refrigerator compartment 101, the temperature inside the medicine storage box 300 is first acquired. If the temperature is higher than the first set value (e.g., 5°C), the valve 400 is opened to connect the air inlet 304 with the refrigerator air duct 200, and the fan 302 is started to introduce cold air into the medicine storage box 300 for cooling. Once the temperature inside the medicine storage box 300 drops to equal to or below the first set value, the next humidity control stage begins.
[0125] Humidity control phase: After the temperature meets the design requirements, the humidity inside the medicine storage box 300 continues to be monitored. If the detected humidity exceeds the fourth set value (e.g., 70% relative humidity), valve 400 is closed, and fan 302 continues to operate, using circulating air to reduce the humidity inside the medicine storage box 300 until the humidity drops to equal to or below the fourth set value. It is understood that closing valve 400 and keeping fan 302 running is primarily to prevent excessive moisture from being introduced from the refrigerated air duct 200. The continuous operation of fan 302 promotes airflow within the box, helping to expel moisture from the medicine storage box 300, thereby reducing humidity and preventing excessive humidity from affecting the quality of the medicine.
[0126] Therefore, the control method provided in this application embodiment can achieve dual control of temperature and humidity, providing a stable and controllable storage environment for pharmaceuticals, thereby reducing the risk of pharmaceutical failure.
[0127] The above are merely preferred embodiments of this application and are not intended to limit the embodiments of this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the embodiments of this application should be included within the protection scope of the embodiments of this application.
