[0050] Figure 1 This is a three-dimensional schematic diagram of a refrigeration appliance according to an embodiment of the present application. It should be noted that: Figure 1 The refrigeration appliance of the present application is exemplified by taking a cross-door refrigerator as an example. In actual application, the scheme of this embodiment can also be applied to other types of refrigeration appliances, such as a French-style double-door refrigerator, or a refrigerator with a freezer compartment on the left, a refrigerator compartment on the upper right, and a temperature-changing chamber on the lower right.

[0051] The refrigeration appliance 1 includes a housing 2. Figure 2 As shown, Figure 2This is a schematic diagram of a refrigeration appliance according to an embodiment of the present application without the two upper doors. The housing 2 of this embodiment defines a first storage chamber 2a and a second storage chamber 2b that are isolated from each other.

[0052] In one embodiment, the first storage chamber 2a is a freezer, and the second storage chamber 2b is a refrigerator. The cabinet 2 includes a partition 5 that separates the first storage chamber 2a from the second storage chamber 2b. The partition 5 thermally isolates the first storage chamber 2a from the second storage chamber 2b. In this embodiment, the partition 5 may include a portion formed of a foamed material and a beam 50 mounted at the front. A hinge 7 is mounted to the partition 5. In this embodiment, the hinge 7 is mounted to the beam 50.

[0053] like Figure 1 As shown, the refrigeration appliance 1 of this embodiment includes four doors. Figure 1 The two doors at the lower side are defined as first doors 3, and the two first doors 3 are arranged side by side and used to close the first storage chamber 2a, i.e., the freezer chamber. Figure 1 The two doors located on the upper side are defined as second doors 4. The two second doors 4 are arranged side by side and are used to close the second storage chamber 2b, i.e., the refrigeration chamber.

[0054] like Figure 1 As shown, located Figure 1 A first door 3 and a second door 4 on the left are arranged side by side along the height direction z of the refrigeration appliance 1. Figure 1 A first door 3 and a second door 4 on the right side are also arranged side by side along the height direction z of the refrigeration appliance 1. In this embodiment, the first door 3 is located below the second door 4.

[0055] In order to more clearly demonstrate the solution of this application, Figure 2 The two second doors 4 on the upper side are omitted.

[0056] Each door of this embodiment is connected to the box body 2 through a hinge 7. Figures 3 to 11 ,in, Figure 3 A schematic three-dimensional diagram of a hinge according to an embodiment of the present application; Figure 4 for Figure 2 Enlarged view of area A in the middle; Figure 5 A partially exploded perspective view of a first door according to an embodiment of the present application; Figure 6 This is a three-dimensional view of the first matching portion of an embodiment of the present application with its bottom facing upward; Figure 7 This is a three-dimensional schematic diagram of an upper end cover according to an embodiment of the present application; Figure 8 for Figure 7 Enlarged view of area B in the middle; Figure 9 for Figure 8 A sectional perspective view along the CC line; Figure 10 This is a partial front view of a refrigeration appliance according to an embodiment of the present application; Figure 11 This is a partial cross-sectional view of a refrigeration appliance according to an embodiment of the present application.

[0057] like Figure 3 As shown, the hinge 7 includes a hinge body 10. The hinge body 10 includes a fixing portion 9, and a fixing member such as a screw passes through a fixing hole 90 to fix the hinge body 10 to the box body 2.

[0058] Figure 3 The hinge 7 shown is Figure 2 Hinge installed in area A. Hinge 7 is used to connect Figure 1 The second door 4 on the upper right side is also used to connect Figure 1 The first door 3 on the lower right side of the center.

[0059] The hinge 7 includes a first hinge shaft 11 extending downward, a first secondary hinge shaft 12, and a second hinge shaft 21 and a second secondary hinge shaft 22 extending upward. The first hinge shaft 11 and the first secondary hinge shaft 12 are used to rotatably connect the first door 3 to the front side of the housing 2. The second hinge shaft 21 and the second secondary hinge shaft 22 are used to rotatably connect the second door 4 to the front side of the housing 2.

[0060] The axis of the first hinge axis 11 and the axis of the second hinge axis 21 are on the same straight line. Figure 11 As shown, it can also be said that the first hinge axis 11 and the second hinge axis 12 are coaxial, that is, line OO.

[0061] The first secondary hinge shaft 12 is rotatably connected to the hinge body 10 via a connecting member 13. The first secondary hinge shaft 12 is rotatable relative to the hinge body 10, but the axis of the first secondary hinge shaft 12 always remains parallel to the axis of the first hinge shaft 11.

[0062] The connecting member 13 includes a rivet 131 , and the first secondary hinge shaft 12 is rotatably connected to the hinge body 10 via the rivet 131 .

[0063] The second secondary hinge shaft 22 is also rotatably connected to the hinge body 10 via a connecting member 23. The second secondary hinge shaft 22 is rotatable relative to the hinge body 10. The axis of the second secondary hinge shaft 22 always remains parallel to the axis of the second hinge shaft 22.

[0064] The second secondary hinge shaft 22 is also rotatably connected to the hinge body 10 via a rivet 131 .

[0065] like Figure 4 、 Figure 5 、 Figure 8 、 Figure 9 and Figure 11As shown, the first door 3 includes a first plane 300 facing the second door 4 and a recessed portion 35 recessed from the first plane 300 toward a direction away from the second door 4 .

[0066] The first plane 300 extends to the front of the recessed portion 35 , and the first matching portion 38 is lower than the first plane 300 in the direction from the first door 3 to the second door 4 .

[0067] like Figures 4 to 6 As shown, the first door 3 includes a first mating portion 38 mating with the first hinge axis 11, and the first mating portion 38 is located within the range of the orthographic projection of the recess 35 on the first plane 300. The first mating portion 38 is lower than the first plane 300 in the direction from the first door 3 to the second door 4.

[0068] The recessed portion 35 can accommodate a portion of the hinge 7 located outside the first mating portion 38 , which will be described in more detail below.

[0069] In this embodiment, the direction from the first door 3 to the second door 4 is the height direction z of the refrigeration appliance 1. In this embodiment, the first mating portion 38 is 3 mm below the first plane in the height direction of the refrigeration appliance. Of course, in other embodiments of the present application, the first mating portion 38 can be 2 mm to 5 mm below the first plane 300 in the direction from the first door 3 to the second door 4, which is also feasible.

[0070] like Figure 4 and Figure 11 As shown, in this embodiment, the top surface of the first matching portion 38 is flush with the bottom surface of the recessed portion 35 .

[0071] When viewed from the front of the refrigeration appliance 1, the first mating portion 38 is obscured by the recessed portion 35. This helps to achieve a more aesthetically pleasing appearance for the refrigeration appliance. Since the first mating portion 38 is obscured, it is not necessary to select a material of the same color as the first surface 300 of the first door 3, especially when such a material or manufacturing process is more expensive.

[0072] like Figure 10 As shown, when viewed from the front of the refrigeration appliance 1, the first door 3 and the second door 4 maintain the same distance D over the entire width of the first door 3. In this embodiment, the distance between the first door 3 and the second door 4 is maintained at 12±2 mm.

[0073] like Figure 4 As shown, the first door 3 includes an upper end cover 31. A first plane 300 is located on the upper end cover 31 and defines the upper surface of the first door 3. The first plane 300 extends across the entire width of the first door 3. The upper end cover 31 also includes a handle groove 33 for a user to reach into to open the first door 3. A recessed portion 35 is located at one end of the handle groove 33.

[0074] In this embodiment, the first mating portion 38 is a component independent of the upper end cover 31. The first door 3 includes a mounting groove 36 open toward the second door 4. The mounting groove 36 is located within the orthographic projection of the recessed portion 35 on the first plane 300, and the first mating portion 38 is disposed within the mounting groove 36.

[0075] like Figure 5 and Figure 6 As shown, the first matching portion 38 is provided with a first hinge groove 381 matching with the first hinge shaft 11 and a first secondary hinge groove 382 matching with the first secondary hinge shaft 12 .

[0076] The first hinge groove 381 extends along at least one direction within the first plane 300 when the first door 3 is closed. In this embodiment, the first hinge groove 381 extends in both the width direction x and the depth direction y of the refrigeration appliance 1 when the first door 3 is closed. The first secondary hinge groove 382 is configured as a circular groove. Figure 2 During the opening process of the first door 3 on the middle right side, the first door 3 not only rotates but also moves in a direction away from the outer wall 20 of the housing 2 corresponding to the side where the hinge 7 is located in area A and toward the first door 3 on the left side. This design is beneficial for embedded installation of the refrigeration appliance 1 in a cabinet, as it can reduce interference between the opening of the first door and the cabinet wall, thereby reducing the gap between the refrigeration appliance and the cabinet, thereby facilitating the integration of the appliance and furniture.

[0077] To guide and position the first mating portion 38, the first mating portion 38 includes a first surrounding wall 383 that encloses the first hinge slot 381. The first mating portion 38 also includes a rib 384 formed on the outside of the first surrounding wall 383 and extending away from the first hinge slot 381. The mounting slot 36 includes a guide slot 364 that mates with the rib 384. During installation of the first mating portion 38, the rib 384 is first aligned with the guide slot 364 to more accurately position the first mating portion 38.

[0078] like Figure 8 As shown, the first matching portion 38 includes a second surrounding wall 385 that surrounds the first secondary hinge slot 382. A rib 384 extending away from the first secondary hinge slot 382 is also formed on the second surrounding wall 385, and the mounting slot 36 is correspondingly provided with a guide slot 364 adapted thereto.

[0079] The mounting groove 36 has a first receiving portion 361 that accommodates the first surrounding wall 383 and a second receiving portion 362 that accommodates the second surrounding wall 385. A guide groove 364 communicates with the first receiving portion 361 and / or the second receiving portion 362. Furthermore, the guide groove 364 has a guide wall 365 that extends obliquely relative to the bottom surface 363 of the mounting groove 36 to guide the first mating portion 38 to its installed position within the mounting groove 36. Once the first mating portion 38 is positioned within the mounting groove 36, a fixing member 37, such as a screw, secures the first mating portion 38 within the mounting groove 36.

[0080] In this embodiment, the first surrounding wall 383 and the bottom surface 363 of the installation groove 36 together form the first hinge groove 381 . The second surrounding wall 385 and the bottom surface 363 of the installation groove 36 together form the first secondary hinge groove 382 .

[0081] In this embodiment, the orthographic projection of the recessed portion 35 on the first plane 300 is larger than the orthographic projection of the mounting groove 36 on the first plane 300. The orthographic projection of the recessed portion 35 on the first plane 300 is located outside the orthographic projection of the mounting groove 36 on the first plane 300. The recessed portion 35 is closer to the second door 4 than the mounting groove 36.

[0082] like Figure 9 and Figure 11 As shown, a first step portion 310 is formed from the first plane 300 to the recessed portion 35 , and a second step portion 320 is formed from the recessed portion 35 to the mounting groove 36 . The first step portion 310 is smaller than the second step portion 320 in the height direction z of the refrigeration appliance 1 .

[0083] As described above, the first secondary hinge shaft 12 is rotatably connected to the hinge body 10 via the connector 13, and the connector 13 is partially located in the recess 35. Specifically, the first secondary hinge shaft 12 is rotatably connected to the hinge body 10 via the rivet 131. The rivet 131 is partially located in the recess 35.

[0084] Therefore, the solution of the present application not only reduces the possibility of interference between the hinge 7 and the first door 3, but also ensures that the distance D between the first door 3 and the second door 4 remains consistent across the entire width of the first door 3, which improves the appearance of the refrigeration appliance. In addition, the thickness of the partition 5 between the first storage chamber 2a and the second storage chamber 2b can be kept relatively small, without having to increase the thickness of the partition 5 to reduce the interference between the hinge 7 and the first door, thereby increasing the effective capacity of the refrigeration appliance.

[0085] Similarly, the second door 4 of this embodiment also includes a second matching portion 39 that matches the second hinge shaft 21. The second matching portion 39 includes a second hinge groove that matches the second hinge shaft 21 and a second secondary hinge groove that matches the second secondary hinge shaft 22, which are not shown in the figure.

[0086] The above is only shown in one embodiment of the present application. Through changes and adjustments, the present application can derive more embodiments.

[0087] For example, in another embodiment of the present application, the second door 4 includes a second plane facing the first door 3 and a recessed portion extending from the second plane toward and away from the first door 3. The second mating portion that mates with the second hinge axis 21 is located within the orthographic projection of the recessed portion. The second plane extends forward of the recessed portion, and the second mating portion is lower than the second plane in the direction from the second door 4 toward the first door 3.

[0088] As in another embodiment of the present application, in order to reduce the distance D between the first door 3 and the second door 4, the first door 3 is provided with a recessed portion 35 recessed in a direction away from the second door 4, and at the same time, the second door 4 is provided with a recessed portion recessed in a direction away from the first door 3.

[0089] Combine Figures 1 to 11 The various embodiments of the individual components described may be combined with one another in any given manner to achieve the advantages of the present application.

[0090] This application has been described with reference to the aforementioned embodiments. However, these embodiments are merely exemplary embodiments of the present application. It should be noted that the disclosed embodiments do not limit the scope of this application. On the contrary, modifications and enhancements made without departing from the spirit and scope of this application are intended to be protected by this patent.
