DETAILED DESCRIPTION

[0028] The present invention will be described in detail below with reference to the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0029] It should be understood that the terms used herein, such as "upper," "above," "lower," and "below," etc., indicating spatial relative positions, are used for ease of explanation to describe the relationship of one element or feature relative to another element or feature as shown in the accompanying drawings. Spatially relative terms may be intended to encompass different orientations of the device in use or operation other than the orientation shown in the drawings.

[0030] An embodiment of the present invention provides a refrigeration device that simplifies the installation process and improves installation stability.

[0031] The refrigeration device 100 of this embodiment can be a refrigerator, a freezer, an upright refrigerator, a wine cabinet, etc. The following embodiments of the refrigeration device 100 are described using a refrigerator as an example. The refrigerator includes a housing 10 and a door. The door and housing 10 together enclose a refrigeration space, which includes a refrigeration compartment, a freezer compartment, and a variable temperature compartment. The refrigerator also includes a hinge assembly 30, through which the door is rotatably connected to the housing 10.

[0032] More specifically, the refrigerator may be a built-in refrigerator, with a cabinet 40 located outside the refrigerator, i.e., the refrigerator is embedded within the cabinet 40. Generally, the outer surface of the refrigerator is flush with the outer surface of the adjacent cabinet 40, resulting in an aesthetically pleasing design. When the refrigerator door is opened, it is necessary to minimize collision with the cabinet 40. If this occurs, interference may result, such as noise or even inability to open the door, significantly impacting the user experience of the built-in refrigerator. The hinge assembly 30 of this embodiment also effectively prevents collisions between the door and the adjacent cabinet 40 when opening, thus meeting the requirements of a built-in refrigerator.

[0033] The hinge assembly 30 includes a box body connecting portion 31, a door body connecting portion 32 and a rotating shaft 33. The box body connecting portion 31 is fixedly connected to the box body 10, and the door body connecting portion 32 is fixedly connected to the door body. Figures 1 to 4 As shown, the hinge assembly 30 of this embodiment takes the hinge connected to the middle crossbeam of the box body 10 as an example. A door body is arranged above the middle crossbeam, and the hinge assembly 30 can also be arranged on the top of the door body. In addition, a door body and a corresponding hinge assembly 30 can also be arranged at other positions of the refrigerator.

[0034] The door body includes a door trim strip 20, a door connecting portion 32 fixedly connected to the door trim strip 20, and a box connecting portion 31 including an axis hole 311. A rotating shaft 33 is disposed between the door trim strip 20 and the door connecting portion 32, and the rotating shaft 33 is inserted into the axis hole 311. This design simplifies the installation process of the hinge assembly 30, reduces the difficulty of alignment, and improves the convenience and stability of the overall installation.

[0035] Specifically, during installation, first install the rotating shaft 33 and the door connecting portion 32 on the door trim 20, and expose the rotating shaft 33. Figure 2 As shown; in the process of installing the door body on the box body 10, the installation is completed by inserting the rotating shaft 33 into the shaft hole 311. This installation process is intuitive and convenient, simplifies the installation process, and at the same time improves the stability after installation and reduces the risk of loosening or misalignment.

[0036] like Figure 2 and Figure 5As shown, the door trim 20 includes a bottom surface 201 and a groove 22 that is recessed on the bottom surface 201 toward the side away from the box connection part 31, and the door connection part 32 is inserted into the groove 22; after the rotating shaft 33 and the door connection part 32 are installed with the door trim 20, the outer surface of the door connection part 32 is flush with the bottom surface 201. In this way, on the one hand, the appearance is beautiful, the door trim 20 and the door connection part 32 are integrated, and the overall consistency is good. On the other hand, depressions or bulges are avoided. After the door connection part 32 and the door trim 20 are installed, its shape is almost the same as the existing door trim 20. That is, on the basis of the appearance being almost the same as the existing structure, the problem of interference or accidental contact between the new structure and other structures can be avoided.

[0037] In addition, Figures 3 to 5 As shown, the hinge assembly 30 also includes a connector 34, through which the door-body connecting portion 32 is connected to the door-body molding 20. The connector 34 can be a bolt, screw, or other structure. The connection of the connector 34 makes the installation of the hinge assembly 30 more compact and stable. The use of the connector 34 further strengthens the connection between the door-body connecting portion 32 and the door-body molding 20, improving the strength and stability of the overall structure and reducing the possibility of loosening and displacement.

[0038] The hinge assembly 30 of this embodiment can be a biaxial hinge, and compared with biaxial hinges with more complex structures, it can better highlight its simple installation method and high positioning accuracy, and meet the requirements of high-precision installation of biaxial hinges.

[0039] In built-in refrigerators, biaxial hinges are used to constrain the door's movement, as the door must avoid collision with adjacent cabinets when opening. Biaxial hinges typically involve multiple axes and slots, and require more parts than traditional single-axis hinges. This makes installation and positioning of these components challenging, and poor assembly precision can affect performance.

[0040] In this embodiment, by directly fixing the biaxial hinge in the door trim 20, when the door and the box body 10 are installed, the door and the box body 10 are still fixed together. Figure 2 As shown, the installation can be completed by simply inserting the rotating shaft 33 into the shaft hole 311.

[0041] like Figures 4 and 5 As shown, the door trim 20 includes a first hinge groove 21, the door connecting portion 32 includes a second hinge groove 321, and the rotating shaft 33 includes a first shaft 331 and a second shaft 332. The first shaft 331 is inserted into the first hinge groove 21, and the second shaft 332 passes through the second hinge groove 321 and is inserted into the shaft hole 311.

[0042] The first hinge slot 21 is a hole built into the door trim 20, while the second hinge slot 321 is located on the door connecting portion 32, which is secured to the door trim 20. Therefore, when the door connecting portion 32 is secured to the box connecting portion 31, the positions of the first hinge slot 21 and the second hinge slot 321 are fixed. Furthermore, the first shaft 331 is inserted into the first hinge slot 21, and the second shaft 332 passes through the second hinge slot 321 and into the shaft hole 311. This allows the first shaft 331 and the second shaft 332 of the rotating shaft 33 to be inserted into the hinge slots of the door trim 20 and the door connecting portion 32, respectively, and pass through the shaft hole 311, simplifying alignment and installation. This design ensures a stable connection for the dual-axis hinge and improves the efficiency and accuracy of overall installation.

[0043] Continue as Figures 4 and 5 As shown, the hinge 33 also includes a connecting rod 333 connecting the first and second shafts 331 and 332. The door trim 20 and / or the door connecting portion 32 include a limiter 23, which restricts the connecting rod 333 to a limited range of motion. By connecting the first and second shafts 331 and 332 via the connecting rod 333 to form an integrated design, the installation process is further simplified. Furthermore, the connecting rod 333 not only connects the two shafts but also, through the limiter 23, restricts their range of motion to a specific area, ensuring the stability and reliability of the hinge during use. This design effectively reduces the difficulty of alignment during installation and improves the durability of the hinge during use.

[0044] like Figures 6-8 As shown, the limiting portion 23 includes a first limiting edge 231 and a second limiting edge 232 disposed on the door trim 20. The area between the first limiting edge 231 and the second limiting edge 232 defines a limited range of motion. When the door is opened to its maximum opening angle, the connecting rod 333 abuts against the first limiting edge 231 or the second limiting edge 232. The first limiting edge 231 and the second limiting edge 232 restrict the rotation shaft 33 when the door is opened to its maximum angle, preventing excessive opening. In other words, not only is the rotation shaft 33 constrained by the first hinge slot 21 and the second hinge slot 321, but the first limiting edge 231 and the second limiting edge 232 also provide additional constraints, protecting the mating relationship between the rotation shaft 33 and the first hinge slot 21 and the second hinge slot 321. This not only protects the structural integrity of the hinge assembly 30, but also extends its service life, ensuring user safety and convenience in daily use.

[0045] In order to clearly express the position and direction described in this embodiment, in this embodiment, the reference gravity direction is defined as downward, the opposite direction is upward, the refrigerator is placed on a horizontal ground, the door is located in front of the box body 10 when closed, the opposite direction is the rear, and the two sides of the plane where the upper and lower front and back are located are the left and right sides respectively. Figure 1 and Figure 3 The hinge assembly 30 in the figure is the lower hinge of the upper door body, and the hinge assembly 30 in the figure is arranged on the right side of the door body, and opens to the right front when the door body is opened.

[0046] like Figure 3 and 4 As shown, the second axis 332 is arranged on the side of the connecting rod 333 facing the box connection part 31, the first axis 331 is arranged on the other side of the connecting rod 333 away from the second axis 332, the second axis 332 is arranged below the connecting rod 333, and the first axis 331 is arranged above the connecting rod 333, that is, the first hinge groove 21 is arranged above the connecting rod 333, and the second hinge groove 321 is arranged below the connecting rod 333.

[0047] In addition, the second shaft 332 is arranged at one end of the connecting rod 333, and the first shaft 331 is arranged at the other end of the connecting rod 333 away from the second shaft 332. The overall shape of the rotating shaft 33 is similar to a crank, which can be conveniently moved in the first hinge groove 21 and the second hinge groove 321 at the same time.

[0048] In addition, during at least part of the process of opening the door body, the first hinge groove 21 and the second hinge groove 321 jointly constrain the rotation shaft 33 to move toward the first side, wherein the first side is the side of the door body away from the hinge assembly 30 on the plane perpendicular to the insertion direction of the rotation shaft 33 into the shaft hole 311 when the door body is closed.

[0049] by Figures 1 to 8 Taking the hinge in the embodiment as an example in which the hinge is arranged on the right side of the door body, and the lower hinge of the door body as an example, the insertion direction of the rotating shaft 33 into the shaft hole 311 is from top to bottom, so the plane perpendicular to the insertion direction of the rotating shaft 33 into the shaft hole 311 is the horizontal plane. On the horizontal plane when the door body is closed, the end of the door body away from the hinge assembly 30 is relative to the left side of the hinge assembly 30. Therefore, during at least part of the process of opening the door body, the first hinge groove 21 and the second hinge groove 321 jointly constrain the rotating shaft 33 to move to the left. That is, the end of the door body away from the hinge rotates to the right, and the rotating shaft 33 moves to the left as a whole. In this way, when the door body turns right to open, the right end of the door body can be prevented from hitting the cabinet 40 on the right.

[0050] Similarly, if the hinge is on the left side of the door, when the door is opened to the left, the first hinge slot 21 and the second hinge slot 321 jointly constrain the shaft 33 to move to the right to prevent the left side of the door from hitting the cabinet 40 on the left.

[0051] In addition, the left side, right side, and first side here refer to the area on one side. For example, when the door body rotates to the right, it does not necessarily move straight to the right. It can be understood that the movement to the first side here does not necessarily move straight to the left. The first hinge groove 21 and the second hinge groove 321 jointly constrain the rotating shaft 33 to move to the left while also constraining the rotating shaft 33 to move forward. This can simultaneously avoid the door body from colliding with the cabinet body 40 and the box body 10, ensuring the stability of the rotating shaft 33 and the smoothness of the opening and closing of the door body, providing better support and avoidance of the cabinet body 40 during use, and improving the user experience of the built-in refrigerator.

[0052] The specific directions of the first hinge groove 21 and the second hinge groove 321 can be designed according to the motion trajectory of the rotating shaft 33 .

[0053] The shaft hole 311 is configured as a special-shaped groove. The end of the second shaft 332 that is inserted into the special-shaped groove is configured as a special-shaped protrusion 3321 that matches the shape of the special-shaped groove. When the special-shaped protrusion 3321 is inserted into the special-shaped groove, the special-shaped protrusion 3321 is relatively fixed to the special-shaped groove. The special-shaped groove here refers to a shape that is different from a complete circle. The special shape can be a triangle, square, oval, waist-shaped, or a circle with several pieces cut away. By inserting the special-shaped protrusion 3321 into the special-shaped groove, the special-shaped protrusion 3321 is relatively fixed to the special-shaped groove, ensuring the fixity and stability of the rotating shaft 33 after installation, simplifying the installation process, and preventing the rotating shaft 33 from loosening or shifting during use, further improving the safety and reliability of the hinge assembly 30.

[0054] The cross-section of the first shaft 331 at the contact point with the first hinge groove 21 is circular; the cross-section of the second shaft 332 at the contact point with the second hinge groove 321 is circular. The circular contact area is relatively small, which reduces friction and wear, ensures the smooth operation of the rotating shaft 33 during the opening and closing process of the door body, improves the durability and service life of the hinge assembly 30, and makes the opening and closing of the door body smoother, more stable and less noisy.

[0055] Compared with the prior art, this embodiment has the following beneficial effects:

[0056] (1) By optimizing the structure and installation method of the hinge assembly 30, the rotating shaft 33 is set between the door trim 20 and the door connecting part 32. In this way, when the door body and the box body 10 are installed, it is only necessary to install the rotating shaft 33 in the shaft hole 311. This installation method is simple and does not involve the precise alignment of multiple parts. The installation speed is fast and the installation effect is good. It simplifies the installation process of the entire hinge assembly 30, reduces the difficulty of alignment, improves the convenience and stability of installation, and at the same time improves the stability of the door body rotation after installation, reduces the risk of loosening or misalignment, and improves the user experience.

[0057] (2) For the dual-axis hinge used in built-in refrigerators, it plays a more efficient installation effect on the complex hinge structure, constrains the movement trajectory of the door body, and further highlights its simple installation method, high positioning accuracy, and meets the requirements of high-precision installation of dual-axis hinges.

[0058] (3) By designing a connecting rod 333 on the rotating shaft 33, the first shaft 331 and the second shaft 332 are connected together to form an integrated structure, further reducing the difficulty of installation. The limiter 23 restricts the connecting rod 333 to a specific range of motion, ensuring the stability of the rotating shaft 33 during use, preventing damage to the hinge assembly 30 caused by excessive movement, and extending the service life of the device. This design not only improves the operating efficiency of the hinge assembly 30, but also reduces the possibility of jamming or wear during use.

[0059] To sum up, this embodiment effectively solves the problems of complex installation, poor stability, low durability and insufficient aesthetics of the traditional hinge assembly 30 through structural optimization and innovative design, significantly improves the installation efficiency and usage experience of the refrigeration equipment 100, and has important application value and market prospects.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation method can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
