For example, people need refrigeration appliances to be applied to different scenarios, such as being able to be embedded in cabinets. Therefore, the movement of the door body of the refrigeration appliance plays an important role in whether the refrigeration appliance can be applied to different scenarios. In the prior art, the door body and the refrigeration appliance are usually connected through a hinge assembly. Summary of the Invention

[0003] An object of this application is to provide an improved refrigeration appliance.

[0004] The technical solution of this application is a refrigeration appliance, including: a box body, the box body includes a storage chamber having an opening on the front side; a plurality of doors, at least one of the doors is rotatably connected to the box body through a hinge assembly to open or close the storage chamber; the hinge assembly includes a first substrate and a first shaft body disposed on the first substrate, and the first shaft body is adapted to cooperate with a first mating portion located on the first end face of the door.

[0005] Wherein, the first substrate includes a recessed portion recessed towards the first end face, and the first shaft body is disposed in the recessed portion.

[0006] When the doors are arranged vertically along the height direction of the refrigeration appliance, in order to obtain as large a storage volume as possible, the gap between the upper door and the lower door is limited. When the occupied space of the hinge assembly in the height direction of the refrigeration appliance becomes larger, the hinge assembly may interfere with the adjacent door. The technical solution of this application reduces the occupied space of the hinge assembly in the height direction of the refrigeration appliance, which helps to reduce the risk of interference between the hinge assembly and its adjacent door.

[0007] In an embodiment of this application, the hinge assembly includes a second shaft body, the second shaft body is adapted to cooperate with a second mating portion located on the first end face, and the second shaft body is disposed in the recessed portion.

[0008] In an embodiment of this application, the hinge assembly includes a second shaft body, the second shaft body is adapted to cooperate with a second mating portion located on the first end face, and the second shaft is installed on the hinge assembly through a connecting portion, and the connecting portion is disposed in the recessed portion.

[0009] In an embodiment of the present application, the first substrate has a main plane, the orientation of the main plane is the same as that of the first end face, the first substrate includes a surrounding portion at least partially surrounding the recess, and the surrounding portion is located on the main plane.

[0010] In an embodiment of the present application, the main plane is parallel to the first end face.

[0011] In an embodiment of the present application, the first substrate includes two oppositely arranged first wall surfaces and second wall surfaces, the second wall surface is farther from the first end face than the first wall surface, and the recess is provided on the second wall surface and is configured to be recessed towards the first wall surface.

[0012] In an embodiment of the present application, the recess depth of the recess towards the first wall surface does not exceed half of the thickness of the first substrate. This helps to reduce the influence of the recess on the local strength performance of the hinge assembly.

[0013] In an embodiment of the present application, the portion of the first wall surface opposite to the recess is coplanar with the remaining portion of the first wall surface.

[0014] In an embodiment of the present application, the first shaft body includes a first connecting portion, and the first connecting portion is configured to mount the first shaft body in the recess, wherein the shapes of the recess and the first connecting portion are substantially adapted to each other. Thus, while meeting the installation requirements of the shaft body, the area of the recess is minimized as much as possible, which helps to reduce the influence of the recess on the strength performance of the hinge assembly.

[0015] In an embodiment of the present application, at least a part of the first connecting portion is received in the recess. This helps to reduce the occupied space of the hinge assembly in the height direction of the refrigeration appliance, thereby reducing interference between the hinge assembly and the adjacent door.

[0016] In an embodiment of the present application, along the width direction of the refrigeration appliance, the recess and the first connecting portion overlap each other.

[0017] In an embodiment of the present application, the projection of the first connecting portion along the height direction of the refrigeration appliance is within the projection range of the recess along the height direction of the refrigeration appliance.

[0018] In one embodiment of the present application, the first substrate includes a main body portion and an extension portion connected to the main body portion. The extension portion cooperates with a door closer installed on the first end face to keep the door closed, and the extension portion is closer to the first end face than the main body portion. When the space occupied by the hinge assembly in the height direction of the refrigeration appliance increases, it will cause the position of the door closer relative to the hinge assembly to change in the height direction of the refrigeration appliance, resulting in uneven force-bearing surfaces between the door closer and the hinge assembly. Thus, the door closer will twist during the process of the user opening and closing the door. In the solution of the present application, the extension portion is closer to the door closer, which is beneficial to making the force on the door closer and the hinge assembly uniform during the process of opening and closing the door, and is beneficial to improving the service life of the door closer.

[0019] In one embodiment of the present application, the extension portion is in the middle area of the thickness of the door closer in the height direction of the refrigeration appliance. This makes the force on the door closer and the hinge assembly uniform during the process of the user opening and closing the door, thereby reducing the phenomenon of the door closer twisting, and is beneficial to improving the service life of the door closer.

[0020] In one embodiment of the present application, the extension portion extends obliquely upward along the height direction of the door relative to the main body portion.

[0021] In one embodiment of the present application, the door closer includes a hook portion. When the door is in the closed state, the extension portion is hooked to the middle area in the thickness direction of the hook portion.

[0022] In one embodiment of the present application, the door closer includes a hook portion. When the door is in the closed state, the extension portion is in surface contact with the hook portion. This increases the force-bearing surface between the door closer and the hinge assembly, and is beneficial to improving the service life of the door closer.

[0023] In one embodiment of the present application, the door closer includes two relatively arranged first structural surfaces and second structural surfaces. The first structural surface and the second structural surface are symmetric with respect to the first plane of the door closer. The first plane is a plane passing through the center point in the thickness direction of the door closer and parallel to the first end face. This is beneficial to increasing the versatility of the door closer and thus reducing the cost of the product.

[0024] In one embodiment of the present application, the door includes a first door and a second door arranged along the width direction of the refrigeration appliance. A door closer is provided on each of the first end faces of the first door and the second door. The first structural surface of the door closer on the first door is closer to the first end face of the first door than the second structural surface, and the second structural surface of the door closer on the second door is closer to the first end face of the second door than the first structural surface.

[0025] In one embodiment of the present application, a first door and a third door are arranged adjacent to each other in the height direction of the refrigeration appliance. The first door is located above the third door. The first door is connected to the cabinet through the hinge assembly.

[0039] In one embodiment of the present application, taking the hinge assembly connected to the first door 23 and located in the middle of the cabinet 1 as an example. As Figures 3 to 6 shown, the first door 23 is connected to the cabinet 3 through the hinge assembly 3. The hinge assembly 3 includes a mounting plate 39 and a first substrate 31. The mounting plate 39 is fixed on the middle part of the cabinet 1, and the first substrate 31 is connected to the first door 23. The end face of the first door 23 connected to the first substrate 31 is defined as the first end face 21, and the surface of the first end face 21 faces the third door 25. Specifically, along the height direction of the refrigeration appliance 100, the first end face 21 is the lower end face of the first door 23.

[0040] In other embodiments, when the third door is connected to the cabinet through a hinge assembly, in order to avoid interference between the first door and the third door, the first end face of the third door is the upper end face of the third door arranged along the height direction of the refrigeration appliance.

[0041] As Figure 4 shown, a first shaft body 32 is arranged on the first substrate 31, and the first shaft body 32 is connected to the first substrate 31. A first fitting portion 211 is provided on the first end face 21 of the first door 23. Specifically, the first fitting 211 portion is configured as a guiding chute, and the first shaft body 32 is inserted into the first fitting portion 211 and slides along the first fitting portion 211 during the opening or closing of the first door 23, thereby restricting the movement trajectory of the door.

[0042] In an embodiment of the present application, a second shaft body 33 is provided on the first substrate 31. The second shaft body 33 includes a fixed shaft 331, a connecting shaft 332, and a rotating plate 333 connecting the fixed shaft 331 and the connecting shaft 332. A second fitting portion 212 is provided on the first end face 21. Specifically, the second fitting portion 212 is configured as a shaft hole. One end of the connecting shaft 332 is rotatably inserted into the second fitting portion 212, the other end of the connecting shaft 332 is vertically fixed on the end face of the rotating plate 333, one end of the fixed shaft 331 is fixed on the first substrate 31 through a second connecting portion 334, the other end of the fixed shaft 331 is connected to the rotating plate 333, and the rotating plate 333 can rotate relative to the fixed shaft 331 so that the rotating plate 333 rotates relative to the first substrate 31.

[0043] As Figure 3 shown, in the embodiment of the present application, the connecting shaft 332 is arranged in parallel with the first shaft body 32. In other embodiments. The second shaft body 33 can be a single rotating shaft connected to the first substrate 31.

[0044] The hinge assembly design in the embodiments of the present application will increase the space occupied by the hinge assembly in the height direction of the cabinet. However, in a multi-door refrigeration appliance, in order not to affect the storage volume of the cabinet, without changing the thickness of the middle cross beam, the gap between the doors is fixed, which will increase the risk of interference between the hinge assembly and its adjacent door. For example, in an embodiment of the present application, a first door 23 and a third door 25 are arranged adjacent to each other along the height direction of the refrigeration appliance 100, the first door 23 is located above the third door 25, the first door 23 is connected to the cabinet 1 through a hinge assembly 3, and the third door 25 is a drawer door. Therefore, in order to avoid interference between the hinge assembly and the door below it and affect the use of the refrigeration appliance, a recessed portion 311 recessed toward the first end face 21 of the first door 23 is provided on the first substrate 31 of the hinge assembly 3, and the first shaft body 32 is arranged in the recessed portion 311.

[0045] As Figures 5 to 6As shown, the first substrate 31 includes two relatively arranged first wall surfaces 313 and second wall surfaces 314, and the second wall surface 314 is farther from the first end surface 21 than the first wall surface 313. The recessed portion 311 is provided at the second wall surface 314 and recesses toward the first wall surface 313.

[0046] To ensure the installation strength of the hinge assembly, the recessing depth of the recessed portion 311 toward the first wall surface 313 does not exceed half of the thickness of the first substrate 31. In the embodiment of the present application, the recessing depth of the recessed portion 311 is 1 mm. In other embodiments, different recessing depths can be selected according to needs.

[0047] As Figure 5 shown, the area of the first wall surface 313 opposite to the recessed portion 311 is coplanar with other partial areas of the first wall surface 313. Specifically, in an embodiment of the present application, the first wall surface 313 is a flat surface and is parallel to the first end surface 21.

[0048] As Figure 3 and Figure 6 shown, the first shaft body 32 includes a first connecting portion 321, and the first connecting portion 321 is configured to mount the first shaft body 32 at the recessed portion 311. In the embodiment of the present application, the first shaft body 32 is riveted at the recessed portion 311 by a riveting process. Thus, the shaft portion of the first shaft body 32 is inserted into the first mating portion 211 of the door 2, and the first connecting portion 321 rivets the first shaft body 32 to the recessed portion 311 in a non-removable manner. In other embodiments, the first shaft body can be connected by other components, such as a bolt-nut combination connection.

[0049] As Figure 6 shown, the first substrate 31 has a main plane 312, and the orientation of the main plane 312 is the same as that of the first end surface 21. The recessed portion 311 is located at the main plane 312. Specifically, the second wall surface 314 defines the main plane 312, and the main plane 312 is parallel to the first end surface 21 of the door. A surrounding portion 351 that at least partially surrounds the recessed portion 311 is provided at the main plane 312. Specifically, the surrounding portion 351 is configured as a plane parallel to the first end surface 21.

[0050] The hinge assembly 3 further includes a second shaft body 33. The second shaft body 33 is disposed at the recessed portion 311, or the second shaft body 33 is disposed at the recessed portion 311 through a second connecting portion 334. In the embodiment of the present application, the second shaft body 33 is disposed at the recessed portion 311 through the second connecting portion 334.

[0051] When there is only one first connecting portion 321 at the recessed portion 311, the shape of the recessed portion 311 is configured to be substantially the same as the shape of the first connecting portion 321; when there are a first connecting portion 321 and a second connecting portion 334 at the recessed portion 311, or even three or more connecting portions, the shape of the recessed portion 311 is adapted to the shape jointly defined by the first connecting portion 321 and the second connecting portion 334. Thus, while meeting the installation requirements of the shaft body, the area of the recessed portion is reduced as much as possible, which is beneficial to reducing the influence of the recessed portion on the strength performance of the hinge assembly.

[0052] As Figure 3 shown, at least a part of the first connecting portion 321 is received in the recessed portion 311. Specifically, along the width direction of the refrigeration appliance 100, the recessed portion 311 overlaps with the first connecting portion 321. In other embodiments, the first connecting portion 321 may be entirely received in the recessed portion 311.

[0053] The projection of the first connecting portion 321 along the height direction of the refrigeration appliance 100 is within the projection range of the recessed portion 311 along the height direction of the refrigeration appliance 100.

[0054] In order to keep the door closed tightly or to automatically close the door when the opening angle of the door is very small, a door closer 4 is provided on the door 2, and the door closer 4 cooperates with the hinge assembly 3 to achieve keeping the door closed tightly.

[0055] As Figure 5 shown, the first substrate 31 includes a main body portion 37 and an extension portion 38 connected to the main body portion 37. The extension portion 38 cooperates with the door closer 4 installed on the first end face 21 of the door 2. Specifically, since the space occupied by the hinge assembly 3 along the height direction of the refrigeration appliance 100 increases, the position of the extension portion 38 relative to the door closer 4 changes, so that the contact area between the extension portion 38 and the door closer 4 becomes smaller or the contact area moves downward along the height of the refrigeration appliance 100. As a result, during the process of opening and closing the door by the user, the force on the door closer 4 is uneven, and it is easy to twist, thus affecting the service life of the door closer 4. Therefore, the extension portion 38 is closer to the first end face 21 relative to the main body portion 37, so that the extension portion 38 is in the middle area of the thickness of the door closer 4 in the height direction of the refrigeration appliance 100.

[0056] Specifically, the door closer 4 includes a hook portion 41. When the door is closed, the extension portion 38 is hooked to the middle area in the thickness direction of the hook portion 41; the extension portion 38 is in surface contact with the hook portion 41. This makes the force on the door closer uniform during the process of opening and closing the door, which is beneficial to improving the service life of the door closer.

[0057] In an embodiment of the present application, the door closer 4 is installed at the lower end face of the door, and the extension portion 38 extends obliquely upward relative to the main body portion 37 along the height direction of the door 2.

[0058] As shown Figure 3 in the figure, the extension portion 38 includes an inclined section 381 and a horizontal section 382. Specifically, when the door is in the closed state and viewed from the front of the refrigeration appliance, the inclined section 381 extends obliquely upward from the main body portion 37 until the middle area of the hook portion 41. In order to increase the contact area between the extension portion 381 and the hook portion 41, a certain distance is continued to extend in the horizontal direction from the end of the inclined section 381 to form the horizontal section 382. The horizontal section 382 is in surface contact with the hook portion 41, which is beneficial to making the force on the door closer and the hinge assembly uniform during the process of the user opening and closing the door, thereby reducing the phenomenon of the door closer twisting and improving the service life of the door closer.

[0059] The door closer 4 includes two oppositely arranged first structural surfaces 42 and second structural surfaces 43. A plane passing through the center point in the thickness direction of the door closer 4 and parallel to the first end face 21 is defined as the first plane 45. The first structural surface 42 and the second structural surface 43 are symmetric with respect to the first plane 45.

[0060] In an embodiment of the present application, a first door 23 and a second door 24 are provided along the width direction of the refrigeration appliance 100, and door closers 4 are respectively provided on the first door 23 and the second door 24. Specifically, along the height direction of the refrigeration appliance 100, the door closers are respectively arranged on the first end face 21 of the first door 23 and the second door 24, that is, the lower end face of the door. In order not to affect the universality of the door closer 4, the extension portion 38 of the hinge assembly 3 extends obliquely upward to cooperate with the door closer 4. The same door closer 4 can be used for the first door 23 and the second door 24. The first structural surface 42 of the door closer 4 located on the first door 23 is closer to the first end face 21 of the first door 23 than the second structural surface 43, and the second structural surface 43 of the door closer 4 located on the second door 24 is closer to the first end face 21 of the second door 24 than the first structural surface 42.

[0061] Combined Figures 1 to 6 The various embodiments of the individual components described can be combined with each other in any given manner to achieve the advantages of the present invention.

[0062] The present application has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present application. It must be pointed out that the disclosed embodiments do not limit the scope of the present application. On the contrary, changes and modifications made without departing from the spirit and scope of the present application fall within the scope of patent protection of the present application.
