Specifically, as shown in fig. 1, in this embodiment, the refrigeration appliance is a refrigerator, and the refrigerator may be a conventional top-bottom opening refrigerator, or may be another type of refrigerator such as a side-by-side refrigerator or a french refrigerator. Of course, in other embodiments, the refrigerator may be a refrigerator, a wine cabinet, or the like.

In this embodiment, the inner door body 2 has an extending structure extending to the outer door body 3, a pivot structure is formed at a position of the extending structure opposite to the outer door body 3 along the height direction of the door body, the pivot structure includes the pivot structure and a hinge 4 fixed on the box body 1, and the hinge 4 extends to the pivot structure and is rotationally matched with the pivot structure. The hinge 4 has a fixing portion 41 fixed to the cabinet 1, an extending portion 42 extending from the fixing portion 41 toward the outer door 3, and a hinge shaft 43 provided between the extending portion 42 and the outer door 3. So that the inner door body 2 and the outer door body 3 can rotate independently relative to the box body 1, and the inner door body 2 and the outer door body 3 can also rotate relatively.

Therefore, through the structure, the inner door body 2 and the outer door body 3 rotate around the hinge shaft 43 on the outer door body 3, so that the hinge shaft 43 is prevented from being arranged on the inner door body 2, the thickness of the inner door body 2 is reduced, the overall size of the refrigeration appliance is reduced, and the miniaturization design is facilitated. And when the hinge pin 43 sets up on outer door body 3, open simultaneously when the interior outer door body, perhaps when outer door body 3 opens alone, can show the distance that reduces the outstanding box 1 lateral wall of a body upset to can reduce the risk of the door body and wall striking after opening, simultaneously, because outstanding distance is less, the refrigeration utensil can further be close to the wall setting, make full use of space improves space utilization.

Specifically, the distance of the protruding box 1 is approximately the distance between the hinge shaft 43 and the front end surface of the outer door 3, and if the hinge shaft 43 is provided on the inner door 2, the distance of the protruding box 1 is also approximately the distance between the hinge shaft 43 and the front end surface of the outer door 3, but the distance includes the thickness of the entire outer door 3 and a portion of the thickness of the inner door 2. Therefore, it is apparent from comparison that the hinge shaft 43 protrudes from the sidewall of the cabinet 1 by a smaller distance when it is provided to the outer door 3.

In the present embodiment, the hinge shaft 43 has a through hole 44 penetratingly disposed in a height direction, and the through hole 44 penetratingly disposed in a radial direction. Therefore, when the hinge shaft 43 is matched with the shaft sleeve 6 and the shaft hole, the hinge shaft 43 can be better attached to the shaft sleeve 6 and the shaft hole, so that a gap between the hinge shaft 43 and the shaft sleeve 6 and the shaft hole is eliminated, and the door body is prevented from shaking.

In the present embodiment, the outer door body 3 has an outer door body 31, a door shaft portion 32 protruding rearward from the outer door body 31, the inner door body 2 has a recessed portion 21 recessed to fit the door shaft portion 32, a recessed portion 22 recessed in the height direction, and the pivot mechanism is provided in the door shaft portion 32 and the recessed portion 22. And the height of the outer door body 31 is higher than the door shaft 32 and the concave part 22, so that the pivoting mechanism is effectively hidden, the user is prevented from directly seeing the pivoting mechanism, the integrity of the refrigeration appliance is improved, and the attractiveness is improved.

The thickness of the outer door body 3 on the pivoting mechanism side is larger than the thickness of the inner door body 2 on the pivoting mechanism side. Therefore, the thickness of the whole door body can be reduced, the cost of the door body can be reduced, and the size of the whole refrigeration appliance can be reduced.

As shown in fig. 2 to 4, which are the first embodiment of the extension structure of the present invention, specifically, the inner door body 2 has an inner door body 23, and the extension structure is a connection structure fixed above the inner door body 23, and the connection structure is rotatably connected to the hinge shaft 43. That is, the inner door body 23 and the connecting structure are of a split structure, thereby facilitating production and assembly.

The hinge shaft 43 is fixedly connected to the extending portion 42, and extends downward to pivotally cooperate with the outer door body 3, the outer door body 3 has a pivot portion 33 rotatably cooperating with the hinge shaft 43, and the pivot portion 33 is a shaft hole recessed from the outer door body 3, so that a pivot axis of the outer door body 3 is the hinge shaft 43.

The connecting structure comprises a connecting piece 5, one end of the connecting piece 5 is fixed with the inner door body 2, and the other end of the connecting piece 5 is provided with a through hole 51 which is pivotally connected with the hinge shaft 43, so that the pivot shaft of the inner door body 2 is also the hinge shaft 43. In this embodiment, the connecting member 5 is a flat plate structure and made of metal, so as to improve the connection stability between the inner door body 2 and the hinge shaft 43, and save cost and space. Of course, in other embodiments, the connecting member 5 may have a structure extending in the horizontal direction and in the height direction, that is, the connecting member 5 is pivotally connected to the hinge shaft 43, not through the through hole 51, but has a hollow tubular structure.

The connecting structure further includes a bushing 6 disposed between the hinge shaft 43 and the connecting member 5, the bushing 6 having a main body 61 extending in the front-rear direction, and a rotating shaft 62 extending downward from the main body 61 and located between the through hole 51 and the hinge shaft 43. The sleeve 6 is made of plastic, and the hinge 4 and the connecting member 5 are made of metal. And the main body part 61 and the connecting piece 5 are jointly fixed on the inner door body 23, so that the shaft sleeve 6 is prevented from being in a movable state. Of course, in other embodiments, the sleeve 6 may be a hollow tubular structure, and only need to be provided with an outwardly protruding structure at the upper end so as to be hung on the connecting piece 5. Therefore, the hinge 4 and the connecting member 5 are separated by the bushing 6, and the hinge 4 and the connecting member 5 are prevented from being in direct contact, thereby reducing noise generated when rotating.

From another perspective, it is also possible to arrange only the bushing 6 to cooperate with the hinge shaft 43, and then the connecting member 5 serves to reinforce the structure. In other words, the sleeve 6 may be used as the connecting member 5, and the connecting member 5 may be used as the reinforcing member.

In this embodiment, the lower part of the inner door body 2 and the outer door body 3 also has a rotating shaft and a shaft hole which are matched with each other, and the inner door body 2 and the outer door body 3 can be assembled together firstly and then are installed together with the box body 1, and the specific process is as follows:

firstly, aligning and mounting rotating shafts and shaft holes below the inner door body 2 and the outer door body 3; secondly, assembling the connector 5 and the bushing 6 together and installing the bushing 6 in the shaft hole of the outer door body 3, and thirdly, fixing the connector 5 and the bushing 6 to the inner door body 2 together. The assembly of the inner door body 2 and the outer door body 3 can be completed through the steps.

As shown in fig. 5 to 10, a second embodiment of the extension structure of the present invention is different from the first embodiment in that: the extension structure extends from the inner door body 23 to the outer door body 3 and is connected with the shaft hole in a rotating manner, namely, the extension structure and the inner door body 23 are integrated.

Specifically, the extension structure has a first groove 7 recessed downward to be rotatably engaged with the hinge shaft 43, so that the pivot axis of the inner door body 2 is the hinge shaft 43, and the pivot axis of the outer door body 3 is the extension structure.

Because the interior door body 2 and the outer door body 3 mainly are the plastic material, for reducing the damaged risk of extension structure and the long-term rotatory complex in shaft hole, the pivot structure still including set up in the downthehole base axle 8 of shaft, the extension structure have upwards sunken with base axle 8 rotatory complex second recess (not shown). Wherein, base shaft 8 is the metalwork, extends structure and base shaft 8 promptly and carries out swivelling joint to avoid extending the inner wall extrusion of structure to the shaft hole, reduce the impaired risk of outer door body 3, still can improve the reliability of interior door body 2 and outer door body 3 swivelling joint.

In this embodiment, the first grooves 7 and the second grooves communicate with each other in the height direction, and therefore, the extension structure is more easily molded. Specifically, when the extension structure is formed, the through hole 51 can be formed by only arranging one element on the mold, and when the first groove 7 and the second groove are not communicated, two elements are required to be arranged to form the first groove 7 and the second groove respectively, of course, in other embodiments, the first groove 7 and the second groove may also be arranged in a non-communicated manner, or the hinge shaft 43 may also be in rotating fit with the base shaft 8, at this time, the pivot shaft of the outer door body 3 is the hinge shaft 43, and therefore, the pivot shaft of the outer door body 3 may be an extension structure or the hinge shaft 43 in different situations.

Further, in order to facilitate the assembly of the inner door body 2 and the outer door body 3 with each other, the pivoting structure further includes an elastic member (not shown) disposed below the base shaft 8, and the outer door body 3 has a detachable portion 34 that is detachable so as to press the base shaft 8 downward. When the inner door body 2 and the outer door body 3 are installed, the specific process is as follows:

firstly, the detaching part 34 of the outer door body 3 is firstly taken down; secondly, aligning and mounting rotating shafts and shaft holes below the inner door body 2 and the outer door body 3; third, the base shaft 8 is pressed downward such that the top of the base shaft 8 is lower than the bottom of the extension structure; fourthly, horizontally moving the extending structure of the inner door body 2 to the upper part of the base shaft 8 and loosening the base shaft 8 to ensure that the base shaft 8 is pivoted in the second groove, and fifthly, installing the detaching part 34. The assembly of the inner door body 2 and the outer door body 3 can be completed through the steps.

Of course, in other embodiments, the extension structure may be directly mounted in the shaft hole of the outer door body 3 by plastic deformation without providing the detachable portion 34.

The first and second embodiments of the extension structure described above can make the inner door 2 and the outer door 3 assembled together first and then assembled together with the cabinet 1. Therefore, the assembling steps are simplified, the assembling efficiency is improved, and particularly, when the refrigerating appliance is high and even higher than the height of a common worker, the inner door body 2 is installed firstly, and then the outer door body 3 is installed, and the installation is not facilitated due to the poor visual angle. Therefore, the above two embodiments of the present invention can effectively avoid the above problems.

The extension structure of the present invention also has a third embodiment (not shown) which is different from the first embodiment in that: the connecting member 5 may also have a rotating shaft, and the rotating shaft extends upward beyond the extending portion 42 of the hinge 4 and extends into the through hole 44 of the hinge shaft 43 from top to bottom to be pivotally connected with the hinge shaft 43.

In summary, in the refrigeration appliance of the present invention, the pivoting mechanism is provided to connect the box body 1, the inner door body 2 and the outer door body 3, the pivoting mechanism enables both the outer door body 3 and the inner door body 2 to rotate outwards to open compared with the box body 1, and the pivot axes of the inner door body 2 and the outer door body 3 are coaxially arranged on the outer door body 3. Therefore, the thickness of the inner door body 2 can be effectively reduced. When the door body is opened, the distance of the door body protruding out of the side edge of the box body 1 is smaller, and space saving is facilitated.

Although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the spirit and scope of the present invention.
