Description

Technical Field

[0001] This application relates to the field of household appliance technology, and more particularly to a refrigeration device. Background Technology

[0002] In related technologies, to enable visual observation of items inside the storage compartment of refrigeration equipment, some refrigeration equipment is equipped with a transparent door structure. This transparent door is typically located within the door frame of the refrigeration equipment and can be constructed using multiple layers of glass of the same size. These multiple layers of glass are spaced apart by spacers to form a hollow cavity. Furthermore, the outer edges of the multiple layers of glass are fitted with sealing elements, which are divided into two sections by an intermediate layer of glass, corresponding to the outer and inner layers of glass.

[0003] However, the aforementioned transparent door structure has significant drawbacks in practical use: when the refrigeration equipment is running, there is a significant temperature difference between the inside (near the storage chamber) and the outside (in contact with the external environment) of the transparent door. Moisture in the outside air easily condenses at the junction of the door frame and the transparent door, forming condensation. This condensation not only affects the appearance and cleanliness of the refrigeration equipment, but long-term accumulation can also lead to dampness and corrosion at the edges of the door frame, and even affect the service life of the door's sealing structure.

[0004] To address the aforementioned condensation problem, relevant comparative documents propose an improvement: by adding heating elements around the spacer, the heat generated by the heating elements can compensate for the temperature loss at the edge of the transparent door, thereby reducing condensation.

[0005] However, in the above solution, the sealing element only achieves sealing through edge bonding and does not form an adaptive design with the structural characteristics of multilayer glass. When the glass undergoes slight deformation due to temperature changes, the sealing element has poor following ability, resulting in unstable sealing effect.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0007] This application addresses, to at least some extent, one of the technical problems in the related art.

[0008] Therefore, this application aims to provide a refrigeration device in which the sealing performance between the panel assembly and the door frame assembly is improved by adjusting the size of the panel and the structure of the sealing element of the door panel assembly, while ensuring stable installation of the heating element and reducing condensation.

[0009] In a first aspect, embodiments of this application propose a refrigeration device, which includes a housing and a door. The housing has a storage chamber inside, and the door is connected to the housing to open or close the storage chamber.

[0010] The door includes a door frame assembly and a panel assembly. The door frame assembly forms an opening that communicates with the storage compartment. The panel assembly is disposed at the opening so that the storage compartment can be observed through the panel assembly. The panel assembly includes a first panel, a second panel, and a third panel. The second panel is disposed on the side of the first panel closer to the storage compartment, and the third panel is disposed on the side of the second panel away from the first panel. In the length direction of the door, the edge of the third panel extends beyond the corresponding edge of the second panel. In the height direction of the door, the edge of the third panel extends beyond the corresponding edge of the second panel.

[0011] The panel assembly includes a first spacer and a second spacer. The first spacer is configured to be circumferentially disposed on the end face of the second panel near the first panel to form a first hollow cavity between the first panel and the second panel. The second spacer is configured to be circumferentially disposed on the end face of the second panel near the third panel to form a second hollow cavity between the second panel and the third panel.

[0012] It also includes a seal, which is provided at least circumferentially along the outer edge of the second panel, and the seal is connected to the edge of the third panel near the end face of the second panel along one side of the depth direction of the door body, and the seal is connected to the end face of the first panel near the second panel along the other side of the depth direction of the door body.

[0013] In the above embodiments, the panel assembly consists of a first panel, a second panel, and a third panel. The second panel is located on the side of the first panel closer to the storage chamber, and the third panel is located on the side of the second panel farther from the first panel. The size of the third panel is larger than that of the second panel, forming an outward expansion structure. The sealing element is circumferentially arranged along the outer edge of the second panel, and the sealing element can connect the third panel and the first panel, thereby enhancing the sealing between the panel assembly and the door frame assembly and reducing the possibility of external hot air entering the storage chamber.

[0014] By setting up a first hollow cavity and a second hollow cavity, heat conduction can be effectively isolated, reducing the direct transfer of heat to the storage chamber through the panel assembly.

[0015] In some possible implementations, the panel assembly includes a heating element disposed within a seal and located near a first spacer and / or a second spacer, the heating element being configured to heat the vicinity of the first spacer and / or the second spacer.

[0016] Furthermore, by embedding the heating wire within the seal and placing it near the first or second spacer, the area near the seal can be heated using the heating element. This effectively prevents condensation from forming at the connection between the panel assembly and the door frame assembly, thus avoiding seal failure or corrosion problems caused by condensation.

[0017] In some possible implementations, the door frame assembly includes a frame and a door insert. The frame is at least partially disposed around the periphery of the panel assembly. A first opening is formed on the frame. The door frame is connected to the first panel on the side away from the storage chamber along the depth direction of the door body. The door insert is connected to the frame. A second opening is formed on the door insert. A third panel is connected to the door insert on the side away from the storage chamber along the depth direction of the door body. The second opening and the first opening form an opening. In the length direction of the door body, the edge of the third panel extends beyond the edge of the door insert.

[0018] The above structural design can lengthen the heat transfer path from the indoor hot air to the storage chamber. The adjusted heat transfer path is along the frame, seals, and third panel to the door liner, which can reduce the impact of indoor hot air on the storage chamber.

[0019] In some possible implementations, the length of the seal along the depth direction of the door body is greater than 7 mm.

[0020] In the above embodiments, the sealing performance is improved by increasing the contact area between the seal and the panel assembly through a larger extension dimension. The seal is thicker in the depth direction, enabling it to withstand greater pressure and ensuring a good seal even during frequent door opening and closing.

[0021] In some possible implementations, the refrigeration device includes an insulation layer configured to fill the first space enclosed by the door frame assembly and the panel assembly. The insulation layer material possesses excellent thermal insulation properties, effectively reducing heat transfer. The insulation layer not only provides thermal insulation but also enhances the overall structural strength of the door.

[0022] In some possible implementations, the refrigeration equipment includes a sealing strip installed at the junction of the frame and the inner liner. The sealing strip further enhances the sealing performance between the door and the cabinet. Furthermore, the sealing strip material typically possesses a degree of elasticity, allowing it to adapt to deformation caused by temperature changes and maintain a long-term sealing effect.

[0023] In some possible implementations, the heating element is disposed between the first panel and the second panel, and the heating element is disposed close to the second panel or close to the first panel.

[0024] With the door closed, the internal temperature of the storage compartment is low, while the outside air temperature is high, easily causing condensation to form on the door surface. The heating element is positioned near the second or first panel to locally heat the area near the seal; this prevents condensation from accumulating between the seal and the panel, avoiding seal failure or corrosion caused by condensation. The heating element, through localized heating, maintains a certain degree of flexibility in the seal, extending its service life and improving the door's sealing stability under different environments. It also partially blocks the heat conduction path, preventing external heat from directly entering the storage compartment through the seal; thus improving the overall thermal insulation performance of the door.

[0025] In some possible implementations, the heating element is disposed between the second panel and the third panel, and the heating element is disposed close to the second panel or close to the third panel.

[0026] In this embodiment, the heating element is positioned close to the third panel, which can heat the area where the third panel contacts the seal; effectively preventing condensation from forming in this area and improving the door's moisture-proof performance.

[0027] The frame includes a frame body and extensions. In some possible embodiments, a first spacer and a seal are connected, and a second spacer and a seal are also connected. The connection between the spacer and the seal improves the stability of the entire door structure. Furthermore, the combination of the spacer and the seal optimizes the heat conduction path and enhances the insulation effect.

[0028] In some possible implementations, the refrigeration unit includes an illumination component disposed within the storage chamber, configured to illuminate the interior space of the storage chamber. The user can observe the interior space of the storage chamber through a panel assembly. Attached Figure Description

[0062] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] This application provides a refrigeration device, which may include refrigerators, freezers, wine cabinets, commercial refrigerated / frozen display cases, etc. Based on the teachings of this application, those skilled in the art can adapt the technical solutions of this application to other refrigeration devices, and all such applications should be included within the protection scope of this application.

[0064] The refrigeration equipment provided in this application embodiment can have various implementation methods, such as a double-door refrigeration equipment, a single-door refrigeration equipment, etc.

[0065] This application provides a refrigeration device including a housing. The housing includes an inner liner defining a storage chamber, an outer shell connected to the outside of the inner liner to form the appearance of the refrigeration device, and a heat insulation layer disposed between the inner liner and the outer shell to insulate the storage chamber.

[0066] The box contains a storage chamber, and the box has an opening that connects to the storage chamber for placing food into or taking food out of the storage chamber.

[0067] The storage room includes a refrigerated compartment. The refrigerated compartment is equipped with at least one refrigerated partition, dividing it into multiple refrigerated storage spaces. Each refrigerated storage space contains a refrigerated drawer for easy access to refrigerated items.

[0068] The storage room includes a freezer compartment, in which at least one freezer partition is provided to divide the freezer compartment into multiple freezer storage spaces. A freezer drawer is provided in at least one freezer storage space for storing frozen items for easy access by the user.

[0069] The refrigerator compartment and the freezer compartment are independent of each other, with the temperature inside the refrigerator compartment being higher than the temperature inside the freezer compartment. For example, the freezer compartment is located below the refrigerator compartment.

[0070] In addition, there are no restrictions on the shape and size of the box; the box can be designed as a cuboid.

[0071] In addition, the modes of refrigeration equipment to achieve refrigeration include, but are not limited to, direct cooling refrigeration, air cooling refrigeration, and hybrid cooling (direct cooling and air cooling). This embodiment mainly uses air cooling refrigeration as an example. Optionally, the refrigeration equipment is equipped with a refrigeration system and an air duct system. The refrigeration system is used to generate cold air, and the air duct system can transport the cold air generated by the refrigeration system to the freezer compartment and the refrigerator compartment of the refrigeration equipment to achieve the purpose of refrigeration in the refrigerator compartment and freezing in the freezer compartment.

[0072] Reference Figure 1 As shown, the refrigeration equipment includes a door 100, which can be connected to the cabinet. The storage compartment can be opened or closed by rotating the door 100. In some embodiments, the door 100 and the cabinet are connected by a hinge.

[0073] Figure 1 In the diagram, the X-axis represents the length of the door 100, the Y-axis represents the depth of the door 100, and the Z-axis represents the height of the door 100.

[0074] In some embodiments, refer to Figure 2 As shown, the door 100 includes a door frame assembly 10. The door frame assembly 10 has an opening that connects to the storage compartment.

[0075] The door 100 includes a panel assembly 20. The panel assembly 20 is located at the opening so that the storage compartment can be viewed through the panel assembly 20.

[0076] In some embodiments, the panel assembly 20 includes multiple panels spaced apart sequentially from the outside of the door 100 to the inside of the door 100, with the multiple panels spaced apart sequentially in a direction from away from the storage room toward closer to the storage room.

[0077] It should be noted that, for those skilled in the art, the number of panels can be adjusted according to needs, and the technical solution of this application does not limit the number of panels.

[0078] In this embodiment, the example is a panel with three layers. (Refer to...) Figure 17As shown, the panel assembly 20 includes a first panel 21, a second panel 22 and a third panel 23. The second panel 22 is disposed on the side of the first panel 21 closer to the storage chamber, and the third panel 23 is disposed on the side of the second panel 22 away from the first panel 21.

[0079] Reference Figure 3 , Figure 4 As shown, the panel assembly 20 includes a first spacer 26, which is configured to be disposed along the periphery of the end face of the second panel 22 near the first panel 21 to form a first hollow cavity 24 between the first panel 21 and the second panel 22.

[0080] It should be noted that perimeter setting refers to the arrangement along the entire edge contour of the outer edge.

[0081] Reference Figure 11 , Figure 12 As shown, the panel assembly 20 includes a second spacer 27 configured to be disposed along the periphery of the end face of the second panel 22 near the third panel 23 to form a second hollow cavity 25 between the second panel 22 and the third panel 23. In some embodiments, the first panel 21, the second panel 22, and the third panel 23 are made of glass.

[0082] It should be noted that the materials used for the first panel 21, the second panel 22, and the third panel 23 must meet the characteristics of transparency and low thermal conductivity.

[0083] The refrigeration unit includes a lighting component located inside the storage chamber, configured to illuminate the interior space of the storage chamber. The user can observe the interior space of the storage chamber through the panel assembly 20.

[0084] The refrigeration equipment includes at least a first heat transfer path that extends along the length of the door frame assembly 10 toward the door panel assembly and then to the first spacer 26 or the second spacer 27.

[0085] Because the first spacer 26 and the second spacer 27 have high thermal conductivity, they can easily transfer the cold energy inside the refrigeration equipment to the panel assembly 20 and the nearby door frame assembly 10. A temperature difference occurs near the first spacer 26 and the second spacer 27, resulting in condensation at the junction of the panel assembly 20 and the door frame assembly 10.

[0086] To address the aforementioned issues, in this embodiment, the panel assembly 20 includes a heating element 28, which is positioned near the first spacer 26 or the second spacer 27. By heating the area near its location using the heating element 28, condensation can be effectively prevented from forming at the connection between the panel assembly 20 and the door frame assembly 10, thus avoiding sealing failure or corrosion caused by condensation.

[0087] The condensation problem of the door 100 can be reduced to some extent by setting the heating element 28. However, the setting of the heating wire destroys the integrity of the sealing element 29. Furthermore, the sealing element 29 is filled between the panels in sections and does not form an overall design that is compatible with the structural features of the multi-layer panel. When the glass undergoes slight deformation due to temperature changes, the sealing element 29 has poor following ability, resulting in unstable sealing effect.

[0088] In some implementations, refer to Figure 5 As shown, in the length direction of the door body 100, the edge of the third panel 23 extends beyond the corresponding edge of the second panel 22, and in the width direction of the door body 100, the edge of the third panel 23 extends beyond the corresponding edge of the second panel 22.

[0089] In some implementations, refer to Figure 3 , Figure 4 , Figure 5 As shown, the panel assembly 20 also includes a seal 29, which is provided at least along the periphery of the outer edge of the second panel 22. The seal 29 is connected to the edge of the end face of the third panel 23 near the second panel 22 on one side along the depth direction, and the seal 29 is connected to the end face of the first panel 21 near the second panel 22 on the other side along the depth direction.

[0090] By setting the size of the third panel 23 to be larger than that of the second panel 22, the second panel 22 and the third panel 23 form an outward expansion structure, allowing the seal 29 to be set along the outer edge of the second panel 22. The seal 29 can connect the third panel 23 and the first panel 21, making the seal 29 a whole. This reduces the contact area between the seal 29 and the panel, reduces the possibility of leakage, enhances the sealing between the panel assembly 20 and the door frame assembly 10, and reduces the possibility of external hot air entering the storage chamber.

[0091] By setting the first hollow cavity 24 and the second hollow cavity 25, heat conduction can be effectively isolated, reducing the direct transfer of heat to the storage chamber through the panel assembly 20.

[0092] Reference Figure 10 , 11 As shown in Figure 12, the heating element 28 is disposed within the sealing element 29. The heating element 28 is disposed near the first spacer 26 and / or the second spacer 27, and the heating element 28 is configured to heat the location thereon.

[0093] It should be noted that the heating element 28 is set in a circle and surrounds the panel. There can be one or more heating elements 28, and the number can be set as needed.

[0094] By embedding the heating wire into the seal 29 and placing it near the first spacer 26 or the second spacer 27, the heating element 28 heats the area near its location, thereby reducing the transfer of cold energy from the spacer to the panel assembly 20 and the door frame assembly 10. This effectively prevents condensation from forming at the connection between the panel assembly 20 and the door frame assembly 10, avoiding sealing failure or corrosion problems caused by condensation.

[0095] The following describes an example of the placement of the heating element 28 when only one heating element 28 is used. Those skilled in the art can combine the placement positions of the heating element 28 as needed.

[0096] In some implementations, refer to Figure 5 As shown, the heating element 28 is disposed between the first panel 21 and the second panel 22, and is disposed close to the second panel 22.

[0097] In some embodiments, the heating element 28 is also disposed close to the first spacer 26 to neutralize the cold energy transmitted due to the low thermal conductivity of the first spacer 26, thereby reducing the temperature difference.

[0098] When the door 100 is closed, the temperature inside the storage room is low, while the temperature outside the air is high. Due to the low thermal conductivity of the first spacer 26 and the second spacer 27, a temperature difference is easily generated at the setting position, and condensation forms on the surface at the position where the temperature difference occurs.

[0099] The heating element 28 is positioned close to the second panel 22 to provide localized heating to the area near the seal 29, preventing condensation from accumulating between the seal 29 and the panel and avoiding seal failure or corrosion caused by condensation.

[0100] The heating element 28 provides localized heating, allowing the sealing element 29 to maintain a certain degree of flexibility; this extends the service life of the sealing element 29 and improves the sealing stability of the door 100 under different environments. It also blocks the heat conduction path to a certain extent, reducing the direct entry of external heat into the storage chamber through the sealing element 29, thus improving the overall thermal insulation performance of the door 100.

[0101] In some implementations, refer to Figure 6 As shown, the heating element 28 is disposed between the first panel 21 and the second panel 22, and the heating element 28 is disposed close to the first panel 21.

[0102] In some embodiments, the heating element 28 is also disposed close to the first spacer 26 to neutralize the cold energy transmitted due to the low thermal conductivity of the first spacer 26, thereby reducing the temperature difference.

[0103] With the door 100% closed, the internal temperature of the storage room is low, while the outside air temperature is high.

[0104] Because the first spacer 26 has a low thermal conductivity, it is easy to generate a temperature difference at the setting position, and condensation will form on the surface at the position where the temperature difference occurs.

[0105] The heating element 28 is positioned close to the first panel 21 to provide localized heating to the area near the seal 29. This prevents condensation from accumulating between the seal 29 and the panel, avoiding seal failure or corrosion caused by condensation. The heating element 28, through localized heating, maintains a certain degree of flexibility in the seal 29, extending its service life and improving the sealing stability of the door 100 under different environments. It also partially blocks the heat conduction path, reducing the direct entry of external heat into the storage chamber through the seal 29, thus improving the overall thermal insulation performance of the door 100.

[0106] In some implementations, refer to Figure 7 As shown, the heating element 28 is disposed between the second panel 22 and the third panel 23, and the heating element 28 is disposed close to the second panel 22.

[0107] In some embodiments, the heating element 28 is also positioned close to the second spacer 27 to neutralize the cold energy transmitted due to the low thermal conductivity of the second spacer 27, thereby reducing the temperature difference.

[0108] In some implementations, refer to Figure 8 As shown, the heating element 28 is disposed between the second panel 22 and the third panel 23, and the heating element 28 is disposed close to the third panel 23.

[0109] In some embodiments, the heating element 28 is also positioned close to the second spacer 27 to neutralize the cold energy transmitted due to the low thermal conductivity of the second spacer 27, thereby reducing the temperature difference.

[0110] The heating element 28 is positioned close to the third panel 23, which can heat the contact area between the third panel 23 and the sealing element 29; effectively preventing condensation from forming in this area and improving the moisture-proof performance of the door 100.

[0111] In some implementations, refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the first spacer 26 is connected to the seal 29, and the second spacer 27 is connected to the seal 29.

[0112] The connection between the spacer and the seal 29 enhances the stability of the entire door structure 100. The combination of the spacer and the seal 29 further optimizes the heat conduction path and improves the insulation effect.

[0113] Reference Figure 2 , Figure 9As shown, the door frame assembly 10 includes a frame 11, which is at least partially surrounding the periphery of the panel assembly 20. A first opening 114 is formed on the frame 11, and the side end face of the frame 11 away from the storage chamber in the depth direction of the door body 100 is connected to the first panel 21.

[0114] Reference Figure 8 , Figure 2 As shown, the door frame assembly 10 includes a door core 12, which is connected to the frame 11. A second opening 121 is formed on the door core 12. A third panel 23 is connected to the side of the door core 12 away from the storage chamber in the depth direction of the door body 100. The second opening 121 and the first opening 114 form an opening.

[0115] Reference Figure 8 As shown, along the length of the door body 100, the edge of the third panel 23 extends beyond the corresponding edge of the door frame 12.

[0116] With the above structural design, the heat conduction path of indoor hot air to the storage chamber can be lengthened. The adjusted heat conduction path is along the frame 11, the seal 29, and the third panel 23 to the door liner 12, which can reduce the impact of indoor hot air on the storage chamber.

[0117] In some implementations, refer to Figure 18 As shown, the door body 100 also includes a storage basket 30. The inner side of the door frame 12 is provided with symmetrically arranged mounting parts. The corresponding position of the storage basket 30 is provided with a mounting fitting part. The storage basket 30 is installed on the inner side of the door frame 12 through the mounting fitting part and the mounting part.

[0118] In some embodiments, the length of the seal 29 is greater than 7 mm along the depth direction of the door body 100.

[0119] Specifically, refer to Figure 5 As shown, the length of the seal 29 along the depth direction is H, and H is greater than 7 mm.

[0120] In the above embodiments, the sealing performance is improved by increasing the contact area between the seal 29 and the panel assembly 20 through a larger extension dimension. The seal 29 is thicker in the depth direction, which can withstand greater pressure and ensure that a good seal is maintained during frequent door opening and closing.

[0121] In some embodiments, refer to Figure 9 As shown, the refrigeration equipment includes a sealing strip 40, which is disposed between the door 100 and the cabinet. In the above embodiment, the sealing performance between the door 100 and the cabinet is further improved by setting the sealing strip 40. Furthermore, the material of the sealing strip 40 typically has a certain degree of elasticity, enabling it to adapt to deformation caused by temperature changes and maintain a long-term sealing effect.

[0122] Reference Figure 5 As shown, the door assembly 100 also includes an insulation layer 50, which is configured to fill the first space enclosed by the door frame assembly 10 and the panel assembly 20.

[0123] Reference Figure 13 , Figure 14 , Figure 15 As shown, the frame 11 includes a frame body 111. The frame body 111 is connected to the door sleeve 12 on the side of the door body 100 closer to the storage chamber in the depth direction. The frame body 111 is connected to the first panel 21 on the end face of the door body 100 away from the storage chamber in the depth direction.

[0124] The frame 11 includes an extension 112, which extends from the side of the frame body 111 away from the storage chamber and away from the first panel 21.

[0125] The frame 11 surrounds the periphery of the panel assembly 20, and the frame body 111 is connected to the door core 12 (inner side) and the first panel 21 (outer side) respectively. The door core 12 is also connected to the third panel 23, forming a three-dimensional connection structure of door core 12-frame 11-panel assembly 20. Through double fixing on the inner and outer sides, the overall structural strength of the door 100 is improved, and the loosening of parts caused by frequent opening and closing is reduced.

[0126] To further reduce the transmission of outside air into the door body, in some embodiments, the door frame assembly 10 includes a partition 113, which is at least partially structurally wrapped around the extension 112.

[0127] It should be noted that the thermal conductivity of the partition 113 is lower than that of the extension 112 and the frame body 111, so as to reduce the transfer of external heat to the interior through the frame body 111 and the extension 112.

[0128] By using the partition 113 to at least cover the extension, the partition 113 can prevent the extension from directly contacting the heat conduction path, reducing the amount of external heat transferred to the panel and spacer of the panel assembly 20 through the extension 112, and thus transferring it to the storage chamber, thereby reducing the loss of internal cooling capacity of the refrigeration system.

[0129] Reference Figure 15 As shown, the partition 113 can simultaneously cover parts of the extension 112 and the frame body 111. Specifically, a part of the partition 113 is wrapped around the extension 112, and another part of the partition 113 covers the end face of the frame body 111 that is away from the first panel 21.

[0130] When the partition 113 simultaneously wraps the extension 112 and covers the end face of the frame body 111, on the one hand, the partition 113 can prevent the extension 112 from directly contacting the heat conduction path, reducing the external heat from entering the panel and spacer of the panel assembly 20 through the extension 112, and then transferring it into the storage room, thus reducing the loss of cold air inside the cabinet; on the other hand, covering the end face of the frame body 111 can fill the gap between the frame 11 and other components, reducing heat leakage from the gaps; the double coverage further improves the overall heat insulation performance of the door 100 and reduces the energy consumption of the refrigeration equipment.

[0131] The partition 113 works in conjunction with the panel assembly 20, which has a three-layer structure with a first, second, and third panel 23 spaced apart. The gaps between the layers form an air insulation layer, reducing heat exchange between the storage chamber and the outside. The partition 113 and the panel assembly 20 work together to reduce heat transfer between the storage chamber and the outside.

[0132] Reference Figure 14 , Figure 15 , Figure 16 As shown, the frame body 111 includes a first part 1111, which extends along the depth direction of the door body 100. The side of the first part 1111 near the storage chamber is connected to the door liner 12.

[0133] The frame body 111 includes a second part 1112. The second part 1112 is connected to one end of the first part 1111. The second part 1112 is configured to extend from the side of the first part 1111 away from the storage chamber toward the direction close to the panel assembly 20. The side of the second part 1112 away from the first part 1111 is connected to the extension member 112, and the end face of the second part 1112 away from the storage chamber is connected to the first panel 21.

[0134] Based on the first part 1111, the second part 1112 extends and supports the integrated structure, forming a rigid connection between the door core 12 and the first panel 21 through the frame body 111. This design avoids the problem of concentrated force at a single connection point. The impact force when the door 100 is opened and closed can be distributed to the entire frame body 111 through the first part 1111 and the second part 1112, reducing the possibility of local deformation.

[0135] Reference Figure 16 As shown, the partition 113 includes a third portion 1131, which is configured to be recessed from the direction away from the storage chamber toward the direction of the storage chamber.

[0136] As an extension structure of the frame body 111, the extension 112 has a certain thermal conductivity and can easily form a heat transfer path between the high-temperature air outside, the frame body 111, the extension 112 and the panel assembly 20. That is, the external heat will be conducted to the junction of the panel assembly 20 and the door frame assembly 10 through the solid structure of the extension 112.

[0137] The third part 1131 and the extension 112 cooperate to form a wrap-around fit. The extension direction of the extension 112 is complementary to the recessed direction of the third part 1131. The end face or side of the extension 112 is covered by the recessed edge, which is equivalent to adding a heat insulation barrier on the outside of the extension 112.

[0138] On the one hand, the heat insulation material of the third part 1131 directly prevents the extension 112 from directly contacting the heat conduction path. On the other hand, the tiny air layer formed between the recessed structure and the extension 112 can further reduce the heat conduction efficiency. The double blockage renders the heat conduction bridge function of the extension 112 ineffective.

[0139] The partition 113 includes a fourth part 1132, which is connected to the side of the third part 1131 away from the panel assembly 20. The fourth part 1132 is disposed in contact with the end face of the second part 1112 away from the first panel 21.

[0140] By positioning the fourth part 1132 at the end face of the second part 1112 away from the first panel 21, the low thermal conductivity of the fourth part 1132 itself can prevent heat from being directly conducted through the solid surface of the second part, thereby reducing the transfer of heat to the storage chamber.

[0141] In some implementations, refer to Figure 15 As shown, the frame body 111 also includes a structure that is recessed from the direction close to the storage chamber to the direction away from the storage chamber.

[0142] Reference Figure 16 As shown, the partition 113 includes a fifth part 1133, which is configured to be recessed toward the first panel 21. The fifth part 1133 is installed in conjunction with the recessed structure on the frame body 111.

[0143] In some practical applications, the partition 113 can be connected to the inner wall of the frame body 111 to maintain the stable position of the partition 113 during the foaming process.

[0144] This application provides a refrigeration device, including a housing and a door 100. The door 100 includes a door frame assembly 10 and a panel assembly 20. The door frame assembly 10 has an opening, and the panel assembly 20 is disposed at the opening. The panel assembly 20 includes a first panel 21, a first spacer 26, a second panel 22, a second spacer 27, and a third panel 23, which are spaced apart. It also includes a heating element 28 and a sealing element 29. The length and width of the third panel 23 are greater than the length and width of the second panel 22, respectively. The sealing element 29 is disposed at least circumferentially along the outer edge of the second panel 22. The sealing element 29 connects the edge of the third panel 23 near the end face of the second panel 22 and the end face of the first panel 21 near the second panel 22 on both sides along the depth direction. By setting the size of the third panel 23 to be larger than the size of the second panel 22, the sealing element 29 can connect the third panel 23 and the first panel 21, enhancing the sealing between the panel assembly 20 and the door frame assembly 10 and reducing the possibility of outside hot air entering the storage chamber.
