Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The following is in conjunction with the appendix Figure 1-5 The present invention describes a refrigerator according to a specific embodiment of the present invention.

[0031] The refrigerator of this invention consists of a refrigerator compartment, a partition, and a defrosting device 10. The partition is installed inside the refrigerator compartment to divide it into a refrigeration area and a functional area 2. The refrigeration area is mainly used to store foods requiring refrigeration and preservation, such as vegetables, fruits, beverages, and cooked foods. The temperature in the refrigeration area is typically set between 0℃ and 4℃, a temperature range that effectively inhibits bacterial growth and extends the shelf life of food. Functional area 2 is specifically designed for defrosting foods, such as pork, beef, and seafood. The temperature range in functional area 2 is typically set between -5℃ and 5℃, a temperature range that ensures the food does not spoil during defrosting while also accelerating the defrosting process.

[0032] The partition of this invention has a first interlayer filled with insulating material. Because the insulating material within the partition effectively reduces heat transfer, the internal environment of the functional area 2 enclosed by the partition is less likely to exchange heat with the external environment. Thus, when food placed in functional area 2 is thawed, it will not affect the environment outside functional area 2, such as the refrigeration and preservation effect of the food in the cold storage area. The insulating material in this invention can be one or more of extruded polystyrene foam, polyurethane foam, and vacuum insulation panels to improve the partition's heat transfer reduction effect and further ensure that the cold storage area and functional area 2 operate independently without affecting each other.

[0033] Furthermore, this utility model also includes a defrosting device 10, which is installed in the functional area 2 to regulate the temperature of the functional area 2. When the defrosting device 10 is working, it raises the ambient temperature within the functional area 2 to defrost the food stored in the functional area 2. The defrosting device 10 can be one or more of a heater, fan, air duct, radio frequency defrosting device, or electrostatic field defrosting device. Users can adjust the operating power of the defrosting device 10 according to their actual needs to ensure that the defrosting process meets their desired time, further improving the user experience.

[0034] According to this invention, a refrigerator is designed with a partition in the refrigerator compartment to form a functional area 2 for defrosting and / or storing food, and a refrigeration area for refrigerating food. A defrosting device 10 is installed in functional area 2 to raise the ambient temperature, thus defrosting the frozen food placed therein. Furthermore, the partition has a first layer filled with insulating material, preventing the defrosting process in functional area 2 from affecting other food stored in the refrigeration area. Therefore, the required food can be placed in the refrigeration area or functional area 2 as needed, simultaneously refrigerating or defrosting different food items, improving the refrigerator's convenience and efficiency.

[0035] Further, see Figure 1 , Figure 1 This is a schematic diagram of a refrigerator according to an embodiment of the present invention, showing the overall layout of the refrigerator. The refrigerator compartment 1 is the area for storing conventional refrigerated foods, and its internal space can be rationally divided according to actual needs to meet the storage requirements of different types of food, such as... Figure 1 As shown, a portion of the refrigerator compartment 1 is the upper space 7, which can be used to store vegetables, fruits, and other foods with high preservation requirements. Functional zone 2 is used for micro-freezing and defrosting. This area is effectively separated from the refrigerator compartment 1 by the upper partition 3, ensuring temperature and functional independence. The upper partition 3 separates the refrigerator compartment 1 and functional zone 2, preventing temperature interference between them. The refrigerator liner 4 is located below functional zone 2. Since functional zone 2 has a freezing function, placing the refrigerator liner 4 below it allows for rapid cooling of functional zone 2 to achieve the purpose of freezing food, while also providing some insulation to reduce the intrusion of external heat. The middle partition 5 is used to divide the micro-freezing and freezing zones 2, allowing different types of food to be frozen or defrosted separately. For example, the space 6 on the left can be used to defrost meats such as beef and pork.

[0036] In some embodiments of this invention, the partition also includes a second interlayer. The second interlayer is located on the side of the first interlayer closest to functional area 2, and is used to install and fill the cold storage medium. When the defrosting device 10 is working, the cold storage medium can absorb some of the heat generated by the defrosting device 10, reducing the heat transfer from the defrosting device 10 to the refrigeration area, thus ensuring the normal operation of the refrigeration area. When the defrosting device 10 stops working, the cold storage medium releases cold energy to maintain the low-temperature environment of functional area 2. The cold storage medium in this invention can be one or more of hydrated salt phase change materials, polyols, and ice slurry, and is not limited here. Preferably, the phase change temperature of the cold storage medium is T, satisfying -15℃≤T≤0℃. This refrigerator, by filling the second interlayer of the partition with a cold storage medium, absorbs and releases cold energy through the cold storage medium, reducing the energy consumption of the refrigeration equipment, improving the service life of the refrigerator, and also reducing temperature fluctuations inside the refrigerator, thus extending the shelf life of food.

[0037] Optionally, in some embodiments of this utility model, the partition has a connecting hole to connect the refrigeration area and the functional area 2. The refrigeration compartment may also be provided with multiple partitions, which enclose the functional area 2, and one or more of the partitions may have a connecting hole to connect the refrigeration area and the functional area 2.

[0038] Understandably, when defrosting is needed, the defrosting device 10 located in functional zone 2 operates, raising the internal temperature of functional zone 2. When defrosting is not required, the defrosting device 10 in functional zone 2 does not operate, and the temperature inside functional zone 2 is unaffected by the defrosting device 10. By creating connecting holes in the partition, cold air from the refrigerator compartment can flow into functional zone 2 through these holes, maintaining a low-temperature environment within functional zone 2, which can then be used for food refrigeration. Thus, functional zone 2 can also be used for food refrigeration when not undergoing defrosting operations, preventing it from occupying space within the refrigerator compartment and thereby improving the utilization rate of the refrigerator's internal space.

[0039] In some embodiments of this invention, the refrigerator further includes a drawer. The functional area 2 of this invention has an open end on its horizontally facing side, and the drawer has an open opening at the top. The drawer is slidably mounted horizontally to the open end of the functional area 2. See also... Figure 5 In this invention, the drawer includes a right drawer 21 and a left drawer 61, and the right drawer 21 and the left drawer 61 are arranged vertically at intervals. The refrigerator also includes a drawer cover 9, which is disposed at one end of the left drawer 61 in the front-back direction. The projected area of ​​the drawer cover 9 in the front-back direction is greater than the sum of the projected areas of the right drawer 21 and the left drawer 61 in the front-back direction.

[0040] Understandably, the right drawer 21 and left drawer 61 can be used to hold food ingredients. The right drawer 21 and left drawer 61 are slidably installed in the functional area 2. Users can retrieve and place food ingredients by pulling the drawer cover 9, which causes the right drawer 21 and left drawer 61 to slide. This drawer structure facilitates the user's retrieval and placement of food ingredients. Furthermore, since the right drawer 21 and left drawer 61 are arranged vertically at intervals, they form two independent storage spaces. Therefore, different food ingredients can be stored separately in the right drawer 21 and left drawer 61, facilitating the isolated storage of food ingredients.

[0041] Furthermore, Figure 5The refrigerator of this invention also shows a structure with a sealing frame 81 and a sealing strip 8. The open end of the functional area 2 is provided with a sealing frame 81, and a sealing strip 8 is provided inside the sealing frame 81. The sealing strip 8 is made of an elastic material, such as silicone or rubber, and has good elasticity and low-temperature resistance. Both the right drawer 21 and the left drawer 61 have a first side wall and a second side wall (not shown) perpendicular to their sliding direction. The first side walls of the right drawer 21 and the left drawer 61 extend into the functional area 2. During the pushing-in process, the first side walls of the right drawer 21 and the left drawer 61 first enter the functional area 2, serving as a guide and positioning element. When the right drawer 21 and the left drawer 61 are fully accommodated within the functional area 2, the second side walls of the right drawer 21 and the left drawer 61 abut against the sealing strip 8, forming a tight seal. The sealing strip 8 acts as a buffer and seal during the pushing-in process of the right drawer 21 and the left drawer 61. Because the sealing strip 8 is made of elastic material, when the second side wall 42 contacts the sealing strip 8, the sealing strip 8 will undergo elastic deformation, filling the tiny gap between the second side wall 42 and the open end of the functional area 212, ensuring a tight seal. When the right drawer 21 and the left drawer 61 are housed inside the functional area 2, the cooperation of the right drawer 21, the left drawer 61, the sealing strip 8, and the sealing frame 81 can isolate the functional area 2 from other spaces in the refrigerator, reducing air convection inside and outside the functional area 2, thereby reducing heat transfer. This effectively reduces heat transfer, maintains the normal operating temperature of the functional area 2, and also prevents temperature changes in the functional area 2 from affecting the temperature of other spaces in the refrigerator, further ensuring the normal operation of all spaces in the refrigerator.

[0042] In some embodiments of this application, the partition also has a first mounting position 321, which is formed as a mounting groove open toward the functional area 2, for mounting the defrosting end of the defrosting device 10. Further, see... Figure 3 , Figure 3 A schematic diagram of the first mounting position 321 is shown. The first mounting position 321 is located on the side of the partition facing functional area 2. The first mounting position 321 is used to stabilize the defrosting device 10, ensuring that the defrosting device 10 will not shake or shift during operation, thus guaranteeing its normal and efficient operation. When the first mounting position 321 adopts a mounting slot design, the mounting slot is located slightly below the center of the partition. This facilitates the placement of food items in functional area 2 for defrosting and utilizes the relatively stable temperature environment at the bottom of the partition. Furthermore, the perimeter of the mounting slot can be provided with an insulation layer, with the mounting slot and insulation layer tightly fitted together. This further reduces heat exchange between functional area 2 and the refrigeration area, preventing the defrosting device 10 from affecting the temperature of the refrigeration area during operation and improving the preservation effect of food items in the refrigeration area.

[0043] In some embodiments of this application, the partition also has a second mounting position for mounting a temperature sensor. Specifically, the temperature sensor faces the functional area 2 and can monitor temperature changes within the functional area 2 in real time, ensuring that the defrosting device 10 operates within a suitable temperature range. Furthermore, through precise temperature monitoring, it can prevent the temperature of the functional area 2 from becoming too high or too low, thereby ensuring that food defrosts at the optimal temperature and extending its shelf life. In addition, placing the temperature sensor in the second mounting position avoids the temperature sensor being too close to the defrosting device 10, which could affect the accuracy of the temperature sensor's detection due to the temperature of the defrosting device 10 during operation.

[0044] In some embodiments of this application, a first mounting hole is provided, which is formed as the aforementioned connecting hole. The functional area 2 and the refrigeration area are connected through the connecting hole, and the defrosting end of the defrosting device 10 can also be installed in the connecting hole. The defrosting device 10 is installed through the connecting hole, which is located in the lower part of the partition. The defrosting end of the defrosting device 10 passes through the connecting hole and extends into the functional area 2, and is well sealed with the hole wall. Installing the defrosting device 10 through the connecting hole can improve the utilization rate of the partition, thereby improving the space utilization rate of the refrigerator.

[0045] See Figure 2This further demonstrates part of the refrigerator structure of this utility model. It includes an upper cover 31, a lower cover 32, a defrosting device 10, a sealing strip 8, a drawer cover 9, and a cooling vent 11. The upper cover 31 and lower cover 32 are located on the upper and lower sides of the defrosting device 10, respectively. They work together to enclose the defrosting device 10, not only protecting it from damage by external impacts but also assisting in the installation of other components. The upper cover 31 is typically made of a sturdy material with certain heat insulation properties, such as engineering plastics or thin metal sheets. It can prevent external dust and moisture from entering the defrosting device 10 area, preventing the defrosting device 10 from being affected by moisture or dust accumulation. In addition to its protective function, the lower cover 32 may also have components connecting to other internal structures of the refrigerator to ensure that the entire defrosting device 10 assembly is securely installed on the side of the refrigerator. The defrosting device 10 is installed near the functional area 2, with its defrosting end facing inwards. It is mainly used for defrosting food placed in the drawers of functional area 2. The defrosting device 10 can employ various technologies to achieve its defrosting function, such as generating heat through resistance wire heating or using microwave technology to cause the internal molecules of food to vibrate and generate heat. During operation, the defrosting device 10 generates heat. To prevent excessive heat loss to other areas of the refrigerator, appropriate heat insulation structures are installed around it, such as the insulation layer on the wall of the mounting slot. The sealing strip 8 is installed at the edge of the open end of the functional area 2, arranged in a ring shape. When the drawer is fully contained within the functional area 2, the second side wall of the drawer will tightly abut against the sealing strip 8. The sealing strip 8 is generally made of rubber material with good elasticity and low-temperature resistance, maintaining its softness and elasticity even at low temperatures, ensuring the sealing of the functional area 2, preventing cold air from leaking into other areas of the refrigerator, and also preventing hot air from entering the functional area 2, thereby maintaining a stable low-temperature environment in the functional area 2. The drawer cover 9 is installed on the outside of the drawer, i.e., the side that the user can directly see and operate. It not only provides some concealment of the food inside the drawer, enhancing the overall aesthetics of the refrigerator, but also facilitates user operation of the drawer. Drawer covers 9 are typically designed with easy-to-grip grooves or handles, making it easier and more convenient for users to push and pull drawers. Furthermore, the material and color of drawer covers 9 can match the overall appearance of the refrigerator, enhancing its overall harmony. Cooling vents 11 are located on the side of the refrigerator near the top, connected to the internal cooling circulation pipes, responsible for delivering the cold air generated by the cooling system to all areas of the refrigerator compartment. The shape and structure of cooling vents 11 are carefully designed, usually with multiple air outlets, and the angle and direction of the outlets are optimized so that the cold air can be evenly distributed to the refrigerator area and functional areas 2, ensuring a uniform and stable temperature in each area. During the cooling process, cold air is blown out from the cooling vents 11, sinks to the bottom of the refrigerator, and then circulates through the gaps in each area, carrying away heat, thereby achieving the refrigeration and micro-freezing functions for food.

[0046] Further, see Figure 4 , Figure 4 The structure of the upper partition 3 and the middle partition 5 is shown, including a first middle partition 51, a middle insulation layer 52, and a second middle partition 53. The middle insulation layer 52 is positioned between the first middle partition 51 and the second middle partition 53. The middle insulation layer 52 uses high-performance insulation materials, such as polyurethane foam, which has a low thermal conductivity, effectively preventing heat transfer, enhancing insulation performance, and reducing cold loss. This structural design helps maintain stable temperatures in different areas of the refrigerator compartment, improving the overall insulation performance of the refrigerator. Figure 4 The structure also shows that a cold storage device 33 and a heat insulation medium layer 34 are provided between the upper cover plate 31 and the lower cover plate 32. The heat insulation medium layer 34 is located above the cold storage device 33 and is connected to the cold storage device 33. This can reduce the heat transfer between the cold storage device 33 and the outside world and further improve the refrigeration efficiency of the refrigerator.

[0047] The refrigerator is equipped with drawers, see below. Figure 5 The diagram showcases the drawer structure, including a right drawer 21, a left drawer 61, a sealing frame 81, and a sealing strip 8. The right drawer 21 and left drawer 61 are used for storing food. The drawer design considers user habits and storage needs, offering good sliding performance and load-bearing capacity. The sealing frame 81 and sealing strip 8 work together to further enhance the drawer's sealing performance when closed, preventing cold air leakage and providing a better environment for food storage. Functional area 2 opens to the horizontal direction, with the top of the drawer also open, and is slidably mounted horizontally at the open end of functional area 2. The drawer has a first sidewall and a second sidewall perpendicular to its sliding direction. The first sidewall extends into functional area 2, and when the drawer is fully contained within functional area 2, the second sidewall closes the open end of functional area 2. Furthermore, the open end of functional area 2 is equipped with a sealing strip 8. When the drawer is fully contained within functional area 2, the second sidewall abuts against the sealing strip 8, further enhancing the sealing and insulation performance of functional area 2.

[0048] The following beneficial effects can be achieved by implementing this utility model:

[0049] 1. Improved Temperature Stability: Functional Zone 2 exhibits minimal temperature fluctuations, maintaining a low temperature without adversely affecting the temperature or equipment reliability of other areas within Functional Zone 2. This is attributed to the double-layer sandwich design of the partition and the application of a cold storage medium, which effectively reduces heat transfer and ensures a constant temperature in Functional Zone 2.

[0050] 2. Minimal impact of defrosting: The defrosting process has minimal impact on other areas inside the refrigerator, ensuring a stable overall temperature environment. The proper installation and insulation measures of the defrosting device 10 effectively control the heat generated during defrosting within functional area 2, avoiding interference with the refrigeration compartment and other areas.

[0051] 3. Functional Integration Advantages: Both defrosting and micro-freezing functions can be performed within Function Zone 2, improving the refrigerator's functionality and refrigeration space utilization. Users can defrost and micro-freeze food without switching between different refrigerator zones or devices, making operation more convenient.

[0052] Compared to traditional refrigerators, this refrigerator has significant advantages in several aspects. Traditional refrigerators lack a multi-functional area that integrates micro-freezing and defrosting functions. When handling meat and other ingredients, users often need to remove them from the freezer and thaw them at room temperature. This method not only takes a long time but also easily leads to bacterial growth on the surface of the food, affecting its quality. However, the functional area 2 of this refrigerator can realize micro-freezing and defrosting functions. Users can directly perform micro-freezing and defrosting treatments on food within functional area 2, making the operation more convenient and effectively ensuring the freshness and safety of the food.

[0053] In terms of heat preservation, traditional refrigerators often have poor insulation between different areas, leading to temperature fluctuations. This refrigerator, however, effectively reduces heat transfer through a double-layered shelf design, a sealed drawer structure, and insulation measures in the defrosting device 10. This ensures temperature stability in the refrigeration zone and functional zone 2, thereby reducing energy consumption.

[0054] Furthermore, this refrigerator boasts higher space utilization. Traditional refrigerators have a relatively limited refrigeration space, failing to meet diverse storage needs. This refrigerator, however, through the rational division of the refrigeration zone and functional area 2, along with optimized space design in each area, better meets users' needs for storing and processing different types of food.
