Abstract
Description
Technical Field
[0001] This application relates to the field of refrigeration technology, and more particularly to a refrigerator. Background Technology
[0002] The door's limiting structure is a core component that ensures controllable door opening angles and prevents excessive opening that could cause structural damage or safety hazards. In a refrigerator, the door is typically connected to the cabinet via hinges. The limiting structure restricts the maximum opening angle of the door to reduce interference between the door and the cabinet or the risk of tipping over.
[0003] In related technologies, limiting structures are prone to failure and have low installation efficiency. Utility Model Content
[0004] This application provides a refrigerator with a limiting structure that is not prone to failure and has high installation efficiency.
[0005] This application provides a refrigerator, including:
[0006] The box-like structure forms a storage compartment;
[0007] A door, rotatably connected to the cabinet to open or close the storage compartment, the door comprising:
[0008] The door body is rotatably connected to the box body;
[0009] The limiting component is integrally set with the door body and is configured to limit the rotation angle of the door body.
[0010] This application provides a refrigerator, which includes a cabinet and a door. The door includes a door body and a limiting member. The door body is rotatably connected to the cabinet. The limiting member is integrally formed with the door body and is configured to limit the rotation angle of the door. By integrating the limiting member with the door body, the connection reliability of the limiting member is high, and it is less prone to loosening due to excessive door opening and closing. Furthermore, the screw fastening process can be eliminated, which improves assembly efficiency. Moreover, by eliminating the separate limiting member and screws, material usage can be reduced.
[0011] In some embodiments, the door body includes:
[0012] Door frame,
[0013] The end cap is located at the end of the door frame along the height direction and is rotatably connected to the box body; the limiting member is located at the end of the end cap away from the door frame along the height direction and is integrally set with the end cap.
[0014] In this way, the limiting component is located at the top and / or bottom of the door, making it difficult for users to observe, which helps to improve the aesthetics.
[0015] In some embodiments, the limiting member and the end cap are integrally formed by injection molding.
[0016] This approach offers low cost, high processing flexibility, and relatively low overall cost.
[0017] In some embodiments, the number of limiting members is at least two, and the at least two limiting members are spaced apart along the width direction of the door and are symmetrical about a plane perpendicular to the width direction.
[0018] This improves the versatility of the door, allowing it to open to the left or right.
[0019] In some embodiments, a hinge is also included, which is connected to the housing, and the door body is provided with a mounting structure, which is rotatably connected to the hinge.
[0020] The limiting component is located on one side of the mounting structure. When the limiting component abuts against the hinge, it restricts the rotation angle of the door.
[0021] In this way, the limiting component abuts against the hinge to achieve the limiting, which is a relatively simple structure and easy to implement.
[0022] In some embodiments, the limiting member protrudes from the end face of the end cover, the outer wall of the limiting member is provided with a first limiting surface, the outer wall of the hinge is provided with a second limiting surface, and when the first limiting surface abuts against the second limiting surface, the limiting member restricts the rotation angle of the door body.
[0023] The first limiting surface matches the second limiting surface.
[0024] This surface contact method for limiting the door's position increases the contact area, which helps distribute stress and effectively avoids localized stress concentration. It also enhances structural durability and extends service life. Furthermore, by improving the fit precision between the first and second limiting surfaces, the controllability of the door's maximum opening angle can be ensured.
[0025] In some embodiments, the device further includes a first reinforcing member located between the mounting structure and the limiting member, and the first reinforcing member is connected to the mounting structure, the limiting member and the end cap respectively.
[0026] This improves the strength of the mounting structure and limiting components, effectively preventing deformation. Furthermore, the first reinforcing component disperses torsional stress during door opening, reducing the risk of breakage of the mounting structure, limiting components, and end caps. Optimized material distribution also reduces localized weak points.
[0027] In some embodiments, the first reinforcement is integrally formed with the end cap.
[0028] This reduces assembly steps and improves overall installation efficiency. Furthermore, it reduces the use of fasteners, thus lowering costs.
[0029] In some embodiments, a second reinforcing member is further included. The limiting member is provided with an inner cavity, and the second reinforcing member is located in the inner cavity. The second reinforcing member is connected to the inner wall of the inner cavity and the end cap, respectively.
[0030] This enhances the overall impact resistance of the limiting component, absorbs vibration energy, and improves its stability.
[0031] In some embodiments, the second reinforcement is integrally formed with the end cap.
[0032] This reduces assembly steps and improves overall installation efficiency. Furthermore, it reduces the use of fasteners, thus lowering costs. Attached Figure Description

[0054] Figure 1 This is a schematic diagram of a partial structure of a door in a related technology. Figure 2 This is a partial exploded view of the door body in the relevant technology.
[0055] See Figure 1 and Figure 2 As shown, in related technologies, the refrigerator door includes a door body 210 and a limiting member 220, which is fixed to the door body 210 by screws. When the door is opened and closed too many times, the screws loosen, causing the limiting member 220 to loosen and its limiting function to fail. Moreover, during assembly, the limiting member 220 needs to be installed separately and secured with screws, increasing the production line cycle time.
[0056] To address the aforementioned technical problems, this application provides a refrigerator, comprising a cabinet and a door. The door includes a door body and a limiting member. The door body is rotatably connected to the cabinet. The limiting member is integrally formed with the door body and is configured to restrict the rotation angle of the door. Thus, by integrating the limiting member with the door body, the connection reliability of the limiting member is high, and it is less prone to loosening due to excessive door opening and closing. Furthermore, the screw fastening process can be eliminated, improving assembly efficiency. Moreover, by eliminating the separate limiting member and screws, material usage can be reduced.
[0057] Figure 3 This is a schematic diagram of the refrigerator door being closed, as provided in an embodiment of this application. Figure 4 This is a schematic diagram of the refrigerator door being opened according to an embodiment of this application.
[0058] This application provides a refrigerator, which can be a single-door, two-door, or multi-door refrigerator.
[0059] See Figure 3 and Figure 4 As shown, the refrigerator includes a cabinet 100. The cabinet 100 is configured to form a storage compartment.
[0060] The housing 100 includes an outer shell 110, a housing liner 120, and a press chamber.
[0061] The outer casing 110 has a first receiving cavity with a first pick-up and drop-out port and a second pick-up and drop-out port. The first pick-up and drop-out port and the second pick-up and drop-out port are respectively located on opposite sides of the outer casing 110 in the depth direction of the housing 100. The first pick-up and drop-out port can be located on the front side of the outer casing 110, and the second pick-up and drop-out port can be located on the rear side of the outer casing 110.
[0062] The compressor compartment is located inside the outer shell 110. The opening of the compressor compartment is opposite to the second access port, allowing the compressor and condenser to be placed inside the compressor compartment via the second access port and the opening. The inner box 120 is located inside the outer shell 110. The inner box 120 forms at least one storage compartment and has a third access port opposite to the first access port, allowing items to be placed inside the storage compartment via the third access port and the first access port.
[0063] A foam layer is filled between the inner chamber 120, the outer shell 110 and the compressor chamber. The foam layer is used to insulate the storage room, thereby ensuring the cooling effect inside the storage room.
[0064] For example, the outer casing 110 may include a first bottom plate, a first top plate, first side plates, and a first back plate, with the first bottom plate and the first top plate disposed opposite each other in the height direction of the casing 100. There are two first side plates, located on either side of the first bottom plate and the first top plate, and connected to them. The two first side plates, the first bottom plate, and the first top plate together form a first access opening. The first back plate is opposite to the first access opening and connected to the first top plate and the two first side plates. The first back plate, the two first side plates, and the first bottom plate together form a second access opening.
[0065] In some possible implementations of this application, the first top plate and the two first side plates can be an integral structure. This configuration simplifies the structure of the outer casing 110, improves the production efficiency of the outer casing 110, and facilitates the assembly of the housing 100. For example, the first top plate and the two first side plates can be formed by bending the same sheet material.
[0066] The press chamber may include a second bottom plate, a second top plate, a second rear plate, and two second side plates. The second bottom plate abuts against the first bottom plate of the outer casing 110 to form the bottom surface of the housing 100. The second top plate is opposite to the second bottom plate in the height direction of the housing 100. The two second side plates are located on both sides of the second bottom plate and the second top plate, and the second side plates connect the second bottom plate and the second top plate. The two second side plates, together with the second bottom plate and the second top plate, form an opening.
[0067] In some possible implementations of this application, the second top plate and the first bottom plate of the outer casing can be an integral structure. This configuration simplifies the structure of the press chamber, facilitates refrigerator assembly, and improves refrigerator production efficiency. Exemplarily, the second top plate and the first bottom plate can be formed by bending the same sheet material.
[0068] The storage room can be at least one, and when there is only one storage room, it can be any one of a refrigerator, freezer, or variable temperature compartment. When there are two or more storage rooms, the multiple storage rooms can include at least one or more of a refrigerator, freezer, or variable temperature compartment.
[0069] See Figure 3 and Figure 4 As shown, the refrigerator includes a door 200, which is rotatably connected to the cabinet 100 to open or close the storage compartment.
[0070] The door 200 is an openable cover located on the front of the cabinet 100 to close and open the storage compartment, allowing users to access items inside. It should be noted that there can be one, two, or more doors 200.
[0071] A refrigerator includes a refrigeration system, which may include a compressor, a condenser, a throttling device, and an evaporator. The compressor, condenser, throttling device, and evaporator are connected in series via piping, through which refrigerant flows. The compressor and condenser may be located in the compressor compartment, while the evaporator is located in the storage compartment.
[0072] When the compressor is working, low-temperature, low-pressure refrigerant is drawn into the compressor and compressed into high-temperature, high-pressure superheated gas in the compressor cylinder before being discharged into the condenser. The high-temperature, high-pressure refrigerant gas dissipates heat through the condenser, and its temperature continuously decreases, gradually being cooled into room-temperature, high-pressure saturated vapor, and further cooled into saturated liquid. The pressure of the refrigerant remains almost constant throughout the entire condensation process.
[0073] The throttling device may include a pressure reducing tube or an electronic expansion valve. In this application, the throttling device is described as including a pressure reducing tube as an example. The pressure reducing tube is low in cost and is not prone to abnormal failure.
[0074] After condensation, the saturated refrigerant liquid is throttled and depressurized through a pressure reducing pipe, transforming into a room-temperature, low-pressure wet vapor. This wet vapor then absorbs heat and vaporizes in the evaporator, lowering not only the temperature of the evaporator and its surroundings but also transforming the refrigerant into a low-temperature, low-pressure gas. The evaporator cools the air inside the storage compartment, lowering its temperature. The refrigerant exiting the evaporator returns to the compressor, repeating the process to ensure continuous cooling of the air inside the storage compartment, thus maintaining the set temperature.

[0076] See Figures 5 to 8 As shown, in some embodiments, the door 200 includes a door body 210, which is rotatably connected to the housing 100.
[0077] The door body 210 includes a door frame 215. The door frame 215 may have two side frames arranged opposite each other along the width direction of the door. The door frame 215 may include a connecting plate located between the two side frames.
[0078] The door body 210 includes an end cap 211, which is disposed at the end of the door frame 215 along the height direction and is rotatably connected to the housing 100. A limiting member is disposed at the end of the end cap 211 opposite to the door frame 215 along the height direction. The height direction is... Figure 3 The direction indicated by the Z-axis.
[0079] Specifically, there are two end caps 211, including an upper end cap and a lower end cap. The upper end cap is located at the top of the door frame 215, and the lower end cap is located at the bottom of the door frame 215.
[0080] The door body 210 includes a panel 212, which can be attached to the outside of the door frame 215 to form the appearance of the door.
[0081] The door body 210 includes an inner door liner 213, which is located inside the door frame 215.
[0082] The door body 210 includes a door insulation component, which can be disposed within the gap between the inner door liner 213 and the door frame 215. The door insulation component insulates the storage compartment to minimize heat exchange between the storage compartment and the outside of the refrigerator, thus ensuring the refrigerator's cooling effect. The door insulation component can be a foam layer.
[0083] The door body 210 includes a door liner 214, which is disposed on the side of the door inner liner 213 opposite to the panel 212. The door liner 214 is arranged around the periphery of the door inner liner 213. The door liner 214 abuts against the housing 100, thereby improving the sealing between the door body 200 and the housing 100.
[0084] See Figures 5 to 8 As shown, in some embodiments, the door 200 includes a limiting member 220. The limiting member 220 is configured to limit the rotation angle of the door 200.
[0085] Specifically, when the door 200 is opened to its maximum angle N, the value of N can be between 90° and 140°. The limiting member 220 abuts against the housing 100 or the hinge, which can limit the further rotation of the door 200. In this way, the door 200 cannot be opened further, and the door 200 can only rotate within a limited angle, effectively avoiding damage to the door 200 due to interference with the housing 100 caused by excessive opening.
[0086] In some embodiments, the limiting member 220 is integrally disposed with the door body 210.
[0087] It is understood that the refrigerator provided in this application embodiment includes a cabinet 100 and a door 200. The door 200 includes a door body 210 and a limiting member 220. The door body 210 is rotatably connected to the cabinet 100. The limiting member 220 is integrally formed with the door body 210 and is configured to limit the rotation angle of the door. In this way, by integrating the limiting member 220 with the door body 210, the connection reliability of the limiting member 220 is high, and it is not easy to loosen due to excessive opening and closing of the door 200. Moreover, the screw fastening process can be eliminated, which is beneficial to improving assembly efficiency. Furthermore, by eliminating the separate limiting member 220 and screws, the amount of material can be reduced.
[0088] In some embodiments, the limiting member 220 is integrally formed with the end cap. In this way, the limiting member 220 is located at the top and / or bottom of the door body 200, making it difficult for the user to observe, which helps to improve the aesthetics.
[0089] In some embodiments, the limiting member 220 may be integrally formed with the lower end cover.
[0090] In other embodiments, the limiting member 220 may be integrally formed with the upper end cover.
[0091] In some embodiments, limiting members 220 are provided on both the upper and lower end covers to form a bidirectional limiting mechanism. This helps prevent the door 200 from swaying up and down due to gravity or external forces during opening. It also improves the overall structural stability of the door 200 and reduces the risk of abnormal closure.
[0092] In some embodiments, the limiting member 220 and the end cap 211 are integrally formed by injection molding.
[0093] Understandably, injection molding offers advantages in terms of low raw material and processing costs, resulting in significant benefits for mass production. Furthermore, the fluidity and plasticity of plastics far surpass those of metals, easily enabling designs that are difficult to achieve with metalworking processes. Injection molding can directly produce parts with cutouts, ribs, snap-fit mechanisms, and internal channels, eliminating the need for subsequent assembly. Moreover, the finished limiting component 220 and end cap 211 are lightweight and possess inherent corrosion-resistant and insulating properties.
[0094] The limiting component 220 and the end cap 211 can be made of POM (polyformaldehyde) plastic. Alternatively, the limiting component 220 and the end cap 211 can be made of PA66 (polyamide 66 or nylon 66) with 30% glass fiber reinforcement. POM plastic is low in cost and has good wear resistance and impact resistance. The PA66 + 30% glass fiber reinforcement material is suitable for a temperature range of -30℃ to 85℃, ensuring the stability of the limiting function.
[0095] In some embodiments, the limiting member 220 and the end cap 211 are metal parts, manufactured by a metal integral forming process (such as forging or casting). Alternatively, the limiting member 220 and the end cap 211 are manufactured as a single unit by welding.
[0096] Figure 9 This is a schematic diagram of the structure of the refrigerator end cap and limiting member provided in the embodiments of this application.
[0097] See Figure 9 As shown, in some embodiments, the number of limiting members 220 is at least two, and the at least two limiting members 220 are spaced apart along the width direction of the door body 200 and are symmetrical about each other about a plane perpendicular to the width direction. This is beneficial to improving the versatility of the door body 200, which can be used for left-opening or right-opening.
[0098] The width direction is the direction shown by the X-axis in the figure.
[0099] Specifically, two limiting members 220 can be provided on one end cap 211. That is, the upper end cap 211 can be provided with two limiting members 220. The lower end cap can be provided with two limiting members 220.
[0100] Figure 11This is a schematic diagram of the hinge structure in a refrigerator provided in an embodiment of this application.
[0101] See Figure 6 , Figure 8 and Figure 11 As shown, in some embodiments, the refrigerator also includes a hinge 300. The hinge 300 is used to enable a rotatable connection between the door 200 and the cabinet 100.
[0102] The hinge 300 is connected to the housing 100. Specifically, the hinge 300 can be fixed to the housing 100 with screws. The hinge 300 is provided with a hinge shaft 310.
[0103] See Figure 10 As shown, the door body 210 is provided with a mounting structure 230, which is rotatably connected to the hinge 300. Specifically, the mounting structure 230 may be provided with a hinge shaft hole, and the hinge shaft 310 is inserted into the hinge shaft hole, thereby realizing the rotatable connection between the door body 200 and the box body 100.
[0104] See Figure 11 As shown, in some embodiments, the hinge 300 is provided with a support foot mounting shaft 320 for mounting support feet. The support foot mounting shaft 320 and the hinge shaft 310 can be coaxially arranged. The support foot mounting shaft 320 is located at the bottom of the hinge shaft 310.
[0105] See Figure 10 As shown, in some embodiments, the mounting structure 230 is disposed on the end cap 211. The mounting structure 230 and the end cap 211 are integrally formed. For example, they are integrally formed by injection molding.
[0106] See Figure 8 and Figure 10 As shown, in some embodiments, the limiting member 220 is located on one side of the mounting structure 230. When the limiting member 220 abuts against the hinge 300, the limiting member 220 restricts the rotation angle of the door body 200. In this way, the limiting is achieved by the limiting member 220 abutting against the hinge 300, which is a relatively simple structure and easy to implement.
[0107] In some embodiments, the mounting structure 230 protrudes from the end face of the end cap 211.
[0108] In some embodiments, the limiting member 220 protrudes from the end face of the end cover 211, the outer wall of the limiting member 220 is provided with a first limiting surface 221, and the outer wall of the hinge 300 is provided with a second limiting surface 330. When the first limiting surface 221 abuts against the second limiting surface 330, the limiting member 220 restricts the rotation angle of the door body 200.
[0109] The first limiting surface 221 and the second limiting surface 330 are matched. The first limiting surface 221 can be a plane, the second limiting surface can be a plane, and the slopes of the first limiting surface 221 and the second limiting surface 330 are matched, thus achieving a close fit between the first limiting surface 221 and the second limiting surface 330. Alternatively, the first limiting surface 221 can be a curved surface, the second limiting surface can be a curved surface, and the concavity and convexity positions and degrees of the first limiting surface 221 and the second limiting surface 330 are matched, or in other words, the radii of curvature of the first limiting surface 221 and the second limiting surface 330 are matched, thus achieving a close fit between the first limiting surface 221 and the second limiting surface 330.
[0110] Understandably, the first limiting surface 221 and the second limiting surface 330 are matched and limit each other using surface contact, increasing the contact area. This helps to distribute the force and effectively avoid local stress concentration, enhancing structural durability and extending service life. Furthermore, by improving the fitting precision between the first limiting surface 221 and the second limiting surface 330, the controllability of the maximum opening angle of the door 200 can be ensured.
[0111] In some embodiments, the mounting structure 230 may be square, circular, or irregular in shape.
[0112] In some embodiments, the door 200 has a large rotation angle, and the hinge 300 may be provided with a matching limiting hole.
[0113] In some embodiments, at least one of the first limiting surface 221 and the second limiting surface 330 is provided with an elastic buffer layer. This elastic buffer layer can absorb impact energy, reduce closing noise, improve the user experience, and meet the requirement of quiet operation. Furthermore, it helps reduce component wear and extend the service life of the limiting member 220 and the hinge 300.
[0114] The elastic buffer layer can be a silicone layer or a rubber layer, etc.
[0115] See Figure 10 As shown, in some embodiments, the door 200 further includes a first reinforcing member 240, which is located between the mounting structure 230 and the limiting member 220. The first reinforcing member 240 is connected to the mounting structure 230, the limiting member 220, and the end cap 211, respectively. This improves the strength of the mounting structure 230 and the limiting member 220, effectively preventing deformation of the mounting structure 230 and the limiting member 220. Moreover, the first reinforcing member 240 can disperse the torsional stress when the door 200 is opened, reducing the risk of breakage of the mounting structure 230, the limiting member 220, and the end cap 211, and reducing local weak points by optimizing material distribution.
[0116] Specifically, the first reinforcing member 240 can be a strip-shaped reinforcing rib.
[0117] The number of first reinforcing members 240 can be at least two, and the at least two first reinforcing members 240 are arranged at intervals. Alternatively, the at least two first reinforcing members 240 are arranged circumferentially around the mounting structure 230.
[0118] In some embodiments, the first reinforcing member 240 is integrally formed with the end cap 211. This helps reduce assembly steps and improves overall installation efficiency. Furthermore, it reduces the use of fasteners, thus lowering costs.
[0119] In some embodiments, the first reinforcing member 240 and the end cap 211 are integrally formed by injection molding.
[0120] Understandably, injection molding offers advantages in terms of low raw material and processing costs, resulting in significant benefits for mass production. Furthermore, the fluidity and plasticity of plastics far surpass those of metals, easily enabling designs that are difficult to achieve with metalworking processes. Injection molding can directly produce parts with cutouts, ribs, snap-fit mechanisms, and internal channels, eliminating the need for subsequent assembly. Moreover, the finished limiting component 220 and end cap 211 are lightweight and possess inherent corrosion-resistant and insulating properties.
[0121] In some embodiments, the door body 200 further includes a second reinforcing member 250, the limiting member 220 is provided with an inner cavity, the second reinforcing member 250 is located in the inner cavity, and the second reinforcing member 250 is connected to the inner wall of the inner cavity and the end cap 211 respectively.
[0122] Understandably, the second reinforcing member 250 can enhance the overall impact resistance of the limiting member 220 and absorb vibration energy, thereby improving the stability of the limiting member 220 in extreme environments (such as temperature cycling tests).
[0123] Specifically, the second reinforcing member 250 can be a mesh-like reinforcing rib. This helps maintain the lightweight design of the limiting member 220 and avoids space occupation caused by increased thickness.
[0124] In some embodiments, the second reinforcing member 250 is integrally formed with the end cap 211. This helps reduce assembly steps and improves overall installation efficiency. Furthermore, it reduces the use of fasteners, thus lowering costs.
[0125] In some embodiments, the second reinforcement 250 and the end cap 211 are integrally formed by injection molding.
[0126] Understandably, injection molding offers advantages in terms of low raw material and processing costs, resulting in significant benefits for mass production. Furthermore, the fluidity and plasticity of plastics far surpass those of metals, easily enabling designs that are difficult to achieve with metalworking processes. Injection molding can directly produce parts with cutouts, ribs, snap-fit mechanisms, and internal channels, eliminating the need for subsequent assembly. Moreover, the finished limiting component 220 and end cap 211 are lightweight and possess inherent corrosion-resistant and insulating properties.
[0127] It should be noted that mechanical simulation analysis of the end cover 211, limiting member 220, and hinge 300 in the refrigerator provided in this application shows that the stress concentration value is less than 15 MPa. The safety threshold is 35 MPa. In other words, the embodiment of this application meets the requirements. Environmental testing shows that after a certain number of door opening and closing cycles from -30℃ to 85℃, the limiting angle deviation is less than 1.5°, meeting the requirements.
