[0055] The present invention will now be described in detail with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the scope of protection of the present invention.

[0056] Figure 1 This is a schematic diagram of the refrigerator structure of the present invention.

[0057] like Figure 1 As shown, a refrigerator includes a cabinet 1 and a control module disposed on the cabinet 1. The refrigerator also has a storage space 10 located inside the cabinet 1 and sealed, and an insulation layer 20 disposed around the storage space 10.

[0058] The insulation layer 20 is used to prevent cold air leakage in the storage space 10, and at the same time, it can prevent condensation when the temperature difference between the storage space 10 and its surrounding environment is too large.

[0059] The housing 1 includes an outer shell 2, an inner liner 3, and an insulation cavity 4 formed between the outer shell 2 and the inner liner 3. The inner liner 3 may have multiple compartments 5.

[0060] The storage space 10 can be one of the independent compartments 5 formed by the inner liner 3. In this case, the insulation layer 20 can be formed by foaming the insulation material filling the insulation cavity 4.

[0061] The storage space 10 can also be a separate space created by installing a partition or other structure with heat insulation function in the compartment 5. In this case, the storage space 10 can be formed by the inner liner 3 and the partition. The heat insulation layer 20 is formed by the heat insulation material filled in the heat insulation cavity 4 and the heat insulation material disposed in the partition.

[0062] Preferably, the refrigerator has a refrigeration space 6 disposed inside the cabinet 1, and the inner liner 3 includes a refrigeration inner liner 7 forming the refrigeration space 6. The storage space 10 is disposed within the refrigeration space 6.

[0063] Figure 2 yes Figure 1 Decomposition diagram of the middle part of the structure.

[0064] like Figure 2 As shown, the refrigerator has an inner wall 30 formed around the storage space 10, the insulation layer 20 is located outside the inner wall 30, and the storage space 10 also has an outer wall 40 sleeved outside the insulation layer 20. The storage space 10 is disposed within the refrigeration space 6 through the outer wall 40.

[0065] The outer wall 40 and the inner liner 7 forming the refrigeration space 6 can be detachably connected. When the storage space 10 needs to be set up inside the refrigerator to store specific items, the storage space 10 can be set up inside the refrigeration space 6 through the outer wall 40. When the storage space 10 is not needed inside the refrigerator, the outer wall 40 can be removed from the inner liner 7, and the storage space 10 can be removed from the refrigeration space 6 to expand the storage capacity of the refrigeration space 6. This design can meet various user needs, improve the utilization rate of the refrigerator's internal space, and is simple in structure and easy to assemble and disassemble.

[0066] Preferably, the outer wall 40 includes a enclosure portion 41 and a top cover portion 42, with the top cover portion 42 detachably mounted on the enclosure portion 41. During assembly, the inner wall 30 and the insulation layer 20, etc., can be installed inside the enclosure portion 41 first, and then the top cover portion 42 can be installed on the enclosure portion 41. This configuration results in a simple structure, convenient assembly and disassembly, and high reliability.

[0067] Furthermore, the refrigerator has a storage opening 11 for connecting the inside and outside of the storage space 10 to retrieve and place items, and a storage door 12 for opening and closing the storage opening 11. A sealing strip 13 that cooperates with the storage door 12 can be provided around the storage opening 11. This configuration can achieve the sealing of the storage space 10, with a simple structure, convenient assembly and disassembly, and good sealing effect.

[0068] Preferably, the storage space 10 may be provided with a storage box 50, the storage box 50 having an accommodating space 51 inside, and the accommodating space 51 being connected to the storage space 10.

[0069] The storage space 10 can be equipped with multiple storage boxes 50. In this case, each storage box 50 can be opened and closed independently. Users can store different items in different storage boxes 50 according to their needs. When a specific item needs to be retrieved, only the specific storage box 50 needs to be opened, which is more convenient and effortless. This design allows for further refined division of the storage space 10 to meet various user needs, improve the utilization rate of the refrigerator's internal space, and features a simple structure that is easy to assemble and disassemble, facilitating the retrieval of items while preventing odor mixing.

[0070] Preferably, the storage space 10 contains only one storage box 50, which is a drawer-shaped box with an open top. The storage door 12 is mounted on the storage box 50, and together with the storage box 50, they form the accommodating space 51. When the storage door 12 is pulled outwards, the storage box 50 opens, and the storage space 10 is also open. When the storage door 12 is pushed inwards, the storage box 50 closes within the storage space 10, and the storage space 10 is then in a closed and sealed state. This design meets various user needs, improves the utilization rate of the refrigerator's interior space, has a simple structure, is easy to assemble and disassemble, and facilitates the retrieval and placement of items.

[0071] Preferably, the refrigerator has a temperature detection device connected to the control module for detecting the temperature of the storage space 10, and a humidity detection device connected to the control module for detecting the humidity of the storage space 10. This configuration allows for precise control of the temperature and humidity of the storage space 10 through temperature and humidity detection data, providing a specific storage environment for specific items, meeting various user needs, and improving the utilization rate of the refrigerator's internal space.

[0072] Preferably, both the temperature detection device and the humidity detection device are located at the rear of the storage space 10 and are spaced a certain distance from the air inlet and outlet of the storage space 10. This arrangement reduces interference from the opening and closing of the storage space 10 and from the air inlet and outlet, thus making the detection results more accurate.

[0073] Figure 3 yes Figure 2 A schematic diagram of the structure of the inner wall 30 as viewed from the front.

[0074] Figure 4 yes Figure 2 A schematic diagram of the structure of the inner wall 30 as viewed from the rear.

[0075] Figure 5 yes Figure 2 A schematic diagram of the first wind turbine and related components from a frontal view.

[0076] Figure 6 yes Figure 5 A schematic diagram of the first wind turbine and related components positioned from the rear.

[0077] Specifically, the storage space 10 is surrounded by a first air duct 60 for supplying cold air to the storage space 10, a second air duct 70 for returning air to the storage space 10, a first air damper located in the first air duct 60 and connected to the control module, a second air damper 71 located in the second air duct 70, and a first fan 80 located in the second air duct 70 and connected to the control module.

[0078] Reference Figure 2 The inner liner 3 of the refrigerated space 6 has a first air vent 71 that cooperates with the first air duct 60 and a second air vent 72 that cooperates with the second air duct 70. An evaporator 8 that communicates with the first air duct 60 can be provided on the rear wall of the inner liner 3 of the refrigerated space 6 to provide cooling for the storage space 10.

[0079] In use, when it is necessary to dry the storage space 10 to reduce its humidity, both the first damper and the second damper 71 can be opened. This allows cold air to enter the storage space 10 from the first air duct 60 through the first damper, while air inside the storage space 10 returns through the second damper 71 from the second air duct 70, thus forming a complete air circulation. The temperature of the storage space 10 can be lowered to below zero degrees Celsius by the cold air, and the airflow can also expel condensed water vapor from the storage space 10. This allows the storage space 10 to become a dry area suitable for long-term storage of dried fruits and other similar foods.

[0080] When it is necessary to increase the humidity within the storage space 10, the first and second air dampers 71 can be closed to create a completely sealed space. After placing moist fresh ingredients such as vegetables inside, the moisture on the vegetables will evaporate naturally, or a small amount of water can be sprinkled inside the storage space 10 to allow the humidity to gradually and naturally increase without requiring additional energy. This creates a relatively humid area within the storage space 10, suitable for preserving fresh fruits and vegetables.

[0081] When the humidity in the storage space 10 is high and may be detrimental to the storage of food, the first air damper can be kept closed, the first fan 80 can be rotated, the second air damper 71 can be opened, and the first fan 80 can drive the air in the storage space 10 to the return air duct, so that the excess water vapor in the storage space 10 can be discharged from the storage space 10, thereby reducing the humidity of the storage space 10.

[0082] When it is necessary to quickly dry the storage space 10, the first fan 80 can be turned on at the same time as the first air damper and the second air damper 71 to accelerate the flow of cold air into the storage space 10.

[0083] This design allows the storage space 10 to function as both a dry zone for storing dried fruits and vegetables and a humid zone for storing fresh fruits and vegetables. When creating a humid zone, the humidity within the storage space 10 can be adjusted to meet various user needs, improve the utilization rate of the refrigerator's interior space, and features a simple structure, convenient setup, and high reliability.

[0084] To prevent the storage space 10 from forming a negative pressure zone, a circulation channel can be provided around the storage space 10 to connect the inside and outside of the storage space 10. The circulation channel can be provided on the inner wall 30 and used to connect the storage space 10 and the refrigeration space 6. Correspondingly, a third air damper can also be provided in the circulation channel.

[0085] The third damper can be connected to the control module and open and close the flow channel under the control of the control module. The third damper can also be configured to automatically open towards the storage space 10 under the force of the wind blowing from the flow channel towards the storage space 10, and automatically close under its own gravity. This configuration is simple in structure, convenient to install, highly reliable, and requires no additional energy consumption.

[0086] The circulation channel can also be located around the first fan 80 and within the return air duct, connecting the return air duct and the storage space 10, and is closed and opened by the second damper 71. This configuration is simple in structure, convenient in installation, and highly reliable.

[0087] Of course, the circulation channel can be omitted. The first fan 80 can be a specific fan that can draw in air from the center and exhaust air from the sides, which can also prevent the storage space 10 from forming negative pressure when the first fan 80 rotates.

[0088] The first damper opens and closes under the control of the control module. The second damper 71 can be connected to the control module and its opening and closing can be controlled by the control module.

[0089] Preferably, the second damper 71 can be pivotally mounted within the second air duct 70. The second damper 71 opens away from the storage space 10 under the action of wind force and closes under its own weight. This configuration is simple, convenient, reliable, and requires no additional energy consumption.

[0090] Furthermore, refer to Figure 5 and Figure 6 The refrigerator has a mounting member 72 disposed on the second air duct 70. The mounting member 72 has a passage opening 721 in its center that connects to the second air duct 70. A mounting base 722 protrudes from the side of the mounting member 72 away from the storage space 10, and the mounting base 722 is open upwards. A pivot shaft 711 is disposed on the second air damper 71 and mates with the mounting base 722. The pivot shaft 711 is pivotally disposed within the mounting base 722. A mating surface 723 is formed around the air vent that mates with the second air damper 71. The mating surface 723 is inclined, and the second air damper 71 rests on the mating surface 723 under its own weight to close the passage opening 721. This design is simple, convenient to install, and highly reliable.

[0091] Figure 7 yes Figure 2 A schematic diagram of the structure of the middle insulation layer 20 as viewed from the front.

[0092] Figure 8 yes Figure 2 A schematic diagram of the structure of the middle insulation layer 20 as viewed from the rear.

[0093] Furthermore, the inner wall 30 includes a first wall 31 located above the storage space 10, the first air duct 60 is located between the first wall 31 and the insulation layer 20, and a first opening 32 is formed on the first wall 31 for connecting the first air duct 60 and the storage space 10.

[0094] This configuration allows cold air to enter from the top of the storage space 10, thereby uniformly cooling and quickly drying the storage space 10. Simultaneously, placing the first air duct 60 between the first wall 31 and the insulation layer 20 reduces cold air loss within the first air duct 60 and prevents condensation from forming due to excessive temperature differences between the inside and outside of the first air duct 60.

[0095] Furthermore, the inner wall 30 includes a second wall 33 located at the rear of the storage space 10, and the second wall 33 has a second opening 34 for connecting the storage space 10 and the second air duct 70. This arrangement allows the storage space 10 to return air from the rear, thereby facilitating the coordination of the second air duct 70 with other return air ducts within the refrigerator, making the refrigerator's air duct layout more rational.

[0096] Figure 9 yes Figure 7 A schematic diagram of the structure of the first insulation section 211.

[0097] Figure 10 yes Figure 7 A schematic diagram of the structure of the second insulation component 22.

[0098] The insulation layer 20 includes a first insulation element 21 sleeved on the inner wall 30 and a second insulation element 22 detachably mounted on the first insulation element 21. A first air duct 60 is formed between the first insulation element 21 and the second insulation element 22, extending in a fan shape along the front-back direction of the storage space 10. The first opening 32 has several such openings. This arrangement facilitates the formation of the first air duct 60, reduces manufacturing difficulty and cost, achieves uniform cooling and rapid drying of the storage space 10, reduces cold loss within the first air duct 60, and prevents condensation due to excessive temperature differences between the inside and outside of the first air duct 60.

[0099] The first insulation component 21 may include a first insulation portion 211 and a second insulation portion 212. The first insulation portion 211 and the second insulation portion 212 are detachably connected. The second insulation component 22 is connected to the first insulation portion 211. During installation, the second insulation portion 212 can be installed inside the outer perimeter first, then the inner liner 3 can be installed inside the second insulation portion 212, then the first insulation portion 211 can be installed on the second insulation portion 212, and then the second insulation component 22 can be installed to form the first air duct 60, and finally the top cover portion 42 can be installed. This configuration is simple in structure, easy to assemble and disassemble, low in cost, and highly reliable.

[0100] Figure 11 This is a schematic flowchart of the refrigerator control method of the present invention. The apparatus for the refrigerator control method of the present invention can be as described above.

[0101] like Figure 11 As shown, a method for controlling a refrigerator.

[0102] The control method includes:

[0103] Obtain the operating mode of the storage space 10;

[0104] When in drying mode, the dryness of the storage space 10 is obtained, and when drying is required, the first air damper and the second air damper 71 are opened;

[0105] When in humidification mode, the humidity of the storage space 10 is obtained. When it is necessary to increase the humidity of the storage space 10, the first air damper and the second air damper 71 are kept closed. When it is necessary to decrease the humidity of the storage space 10, the first air damper is kept closed, the first fan 80 is started and the second air damper 71 is opened.

[0106] The aforementioned operating modes include both a drying mode and a humidification mode. The drying mode maintains the storage space 10 at a low temperature and in a dry state, suitable for long-term storage of dried fruits and other items requiring drying. The humidification mode maintains the storage space 10 at a suitable temperature and humidity for preserving fresh produce. Since excessive humidity is detrimental to the preservation of fresh ingredients, in the humidification mode, a fan needs to be activated to reduce the humidity in the storage space 10 when it becomes too high.

[0107] This control method allows the storage space 10 to have different humidity and temperature under different working modes. It enables the storage space 10 to form both a dry zone for storing dried fruits and vegetables and a humid zone for storing fresh fruits and vegetables. When forming a humid zone, the humidity within the storage space 10 can be adjusted to meet various user needs, improve the utilization rate of the refrigerator's internal space, and features a simple structure, convenient setup, and high reliability.

[0108] Preferably, the control method may further include: when the storage space 10 is in drying mode and requires faster drying, simultaneously opening the first damper and the second damper 71 and starting the first fan 80. This configuration accelerates the flow of cold air into the storage space 10, thereby rapidly reducing the temperature of the storage space 10 and improving the efficiency of cooling and drying.

[0109] Figure 12 yes Figure 11 A flowchart illustrating the first control method for obtaining the operating mode.

[0110] like Figure 12 As shown, preferably, the refrigerator may further include a user input module connected to the control module, and the control method for "obtaining the operating mode of the storage space 10 inside the refrigerator" specifically refers to:

[0111] Start the user input module;

[0112] Obtain the operating mode of the storage space 10 selected by the user.

[0113] This setup allows for direct confirmation of the operating mode of the storage space 10 through human-computer interaction, eliminating the need for additional recognition and processing modules, thus reducing costs and increasing work efficiency.

[0114] Furthermore, after obtaining the operating mode selected by the user, the control method may further include:

[0115] Obtain information about the items stored in the storage space 10.

[0116] Based on the item information, obtain a suitable storage environment for the item.

[0117] Obtain the operating mode of the storage space 10 corresponding to the storage environment;

[0118] Determine whether the operating mode selected by the user is incorrect;

[0119] If so, correct the operating mode.

[0120] With this setting, if the user selects the wrong operating mode due to mistake or misjudgment, the refrigerator can automatically correct it to ensure the correct operating mode and prevent food damage caused by unsuitable storage environment.

[0121] In addition, the storage space 10 may also be equipped with an item recognition module connected to the control module, and the control method for "obtaining the operating mode of the refrigerator storage space 10" may specifically refer to:

[0122] Obtain information about the items stored in the storage space 10.

[0123] Based on the item information, obtain a suitable storage environment for the item.

[0124] Obtain the operating mode of the storage space 10 corresponding to the storage environment.

[0125] The item recognition module can be an image recognition and analysis module or a sensor recognition module. That is, an electronic tag carrying food information is placed on the item, and the control module learns the information of the item stored in the storage space 10 by reading the electronic tag.

[0126] This design makes the refrigerator more intelligent, reduces the difficulty of use for users, and improves the user experience.

[0127] Figure 13 yes Figure 11 A flowchart illustrating another control method for obtaining the operating mode.

[0128] like Figure 13 As shown, the refrigerator may further include a humidity detection device for detecting the humidity within the storage space 10, and the control method for "obtaining the operating mode of the storage space 10" may specifically refer to:

[0129] After an item is placed into the storage space 10, the first fan 80 is kept off and the first damper and the second damper 71 are kept closed.

[0130] Obtain the humidity value of the storage space 10;

[0131] Calculate the humidity variation range of the storage space 10;

[0132] The appropriate storage environment for the items is determined based on the humidity variation.

[0133] Obtain the operating mode of the storage space 10 corresponding to the storage environment.

[0134] Since fresh fruits and vegetables typically carry water droplets and their moisture evaporates, the humidity level tends to rise in a short period. Dried fruits, being drier, absorb moisture from the air, resulting in a decrease in humidity levels over a short time. Therefore, the humidity level within the storage space 10 after the items are placed inside is used to determine the suitable storage environment for those items.

[0135] This setup eliminates the need for additional recognition and processing modules, reducing costs and increasing efficiency. It makes the refrigerator more intelligent, reduces the difficulty of use for users, and improves the user experience.

[0136] Figure 14 yes Figure 13 A flowchart illustrating the control method for obtaining humidity values.

[0137] like Figure 14 As shown, the control method of "activating the humidity detection device and acquiring the humidity value of the storage space 10" specifically refers to:

[0138] Obtain the first humidity value of the storage space 10 and start timing;

[0139] When the timer reaches the first set time, the second humidity value in the storage space 10 is obtained and the timer is restarted.

[0140] When the timer reaches the first set time, the third humidity value in the storage space 10 is obtained and the timer is restarted.

[0141] The number of cycles for the above steps can be determined based on the number of humidity values ​​to be collected. Preferably, there should be at least three humidity values, and "calculating the change range of humidity in the storage space 10" means calculating the percentage of two adjacent humidity values ​​and then averaging the multiple percentages to obtain the change range of humidity in the storage space 10.

[0142] This setup eliminates the need for additional recognition and processing modules, reducing costs and increasing efficiency. It makes the refrigerator more intelligent, reduces the difficulty of use for users, and improves the user experience.

[0143] Figure 15 yes Figure 11A flowchart illustrating the control method of the first fan 80.

[0144] like Figure 15 As shown, preferably, the control method for the first fan 80 includes:

[0145] Start the first fan 80 and begin timing;

[0146] When the timer reaches the second preset time, the first fan 80 is disconnected and the humidity of the storage space 10 is obtained. When it is necessary to further reduce the humidity, the timer is reset and the above steps are repeated sequentially.

[0147] Of course, the control method of the first fan 80 can also be that the humidity detection device detects the humidity of the storage space 10 in real time, and stops the first fan 80 when the humidity of the storage space 10 drops to the target humidity.

[0148] By adopting a control method that automatically stops and restarts the fan after a specific period of operation, the air in the storage space 10 can be mixed evenly for a certain period of time, thereby making the detection results more accurate and the humidity regulation in the storage space 10 more precise. At the same time, the humidity detection device does not need to be in detection mode all the time, which saves more energy and is easier to control.

[0149] The refrigerator includes a temperature detection device for detecting the temperature inside the storage space 10. When the temperature of the storage space 10 is higher than the set temperature of the drying mode, it is determined that drying treatment is required. This configuration allows for precise control of the temperature and humidity of the storage space 10 through temperature and humidity detection data, providing a specific storage environment for specific items, meeting various user needs, and improving the utilization rate of the refrigerator's internal space.

[0150] In summary, the refrigerator control method of the present invention can solve the problems of single-function storage space, inability to meet diverse user storage needs, and low utilization rate of storage space. By adopting the technical solution in this application, the storage space 10 can form both a dry zone for storing dried fruits and vegetables and a humid zone for storing fresh fruits and vegetables. When forming the humid zone, the humidity within the storage space can be adjusted to meet various user needs, improve the utilization rate of the refrigerator's internal space, and features a simple structure, convenient setup, and high reliability.

This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
