detailed description

The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. However, this embodiment does not limit the present invention, and any structural, method, or functional changes made by those skilled in the art according to this embodiment are included in the protection scope of the present invention.

Please refer to Fig. 1 to Fig. 10 to show the embodiment of the refrigerating appliance of the present invention, the refrigerating appliance includes a box body 1, an inner door body 2 for opening or closing the box body 1, and an outer door body arranged on the outside of the inner door body 2 3. Wherein, the refrigeration appliance further includes a pivot mechanism connecting the box body 1, the inner door body 2 and the outer door body 3, and the pivot mechanism makes the outer door body 3 and the inner door body 2 comparable The box body 1 is rotated outwards to open, and the pivot shafts of the inner door body 2 and the outer door body 3 are coaxially arranged on the outer door body 3 .

Specifically, as shown in FIG. 1 , in this embodiment, the refrigerating appliance is a refrigerator, and the refrigerator may be a traditional top-and-bottom refrigerator, or a side-by-side refrigerator, a French refrigerator, or other refrigerators. Of course, in other embodiments, the refrigeration appliance may also be a refrigerator, a wine cabinet, and the like.

In this embodiment, the inner door body 2 has an extension structure extending to the outer door body 3, and a pivot structure is formed at a position opposite to the outer door body 3 along the height direction of the door body. The rotating mechanism includes the pivoting structure and a hinge 4 fixed on the box body 1 , the hinge 4 extends to the pivoting structure and cooperates with the pivoting structure in rotation. The hinge 4 has a fixing part 41 fixed on the box body 1 , an extension part 42 extending from the fixing part 41 toward the outer door body 3 , and a hinge shaft 43 arranged between the extension part 42 and the outer door body 3 . Therefore, both the inner door body 2 and the outer door body 3 can be independently rotated relative to the box body 1, and the inner door body 2 and the outer door body 3 can also be made to rotate relative to each other.

Therefore, through the above structure, the inner door body 2 and the outer door body 3 all rotate around the hinge shaft 43 on the outer door body 3, thereby avoiding the setting of the hinge shaft 43 on the inner door body 2, and further reducing the inner door body 2. The thickness reduces the overall volume of the refrigeration appliance, which is beneficial to the miniaturization design. And when the hinge shaft 43 is arranged on the outer door body 3, when the inner and outer doors are opened at the same time, or when the outer door body 3 is opened separately, the distance from the side wall of the box body 1 can be significantly reduced when the door body is overturned, thereby reducing the distance of the door body. There is no risk of colliding with the wall after opening. At the same time, due to the small protrusion distance, the refrigeration appliance can be further installed close to the wall, making full use of the space and improving the space utilization rate.

Specifically, the distance from the side wall of the above-mentioned protruding box body 1 is roughly the distance between the hinge shaft 43 and the front end surface of the outer door body 3, and if the hinge shaft 43 is arranged on the inner door body 2, then the above-mentioned protruding box body 1 side The distance of the wall is roughly the distance between the hinge axis 43 and the front end of the outer door body 3 , but this distance includes the thickness of the entire outer door body 3 and part of the thickness of the inner door body 2 . Therefore, by comparison, it is obvious that when the hinge shaft 43 is arranged on the outer door body 3, the distance protruding from the side wall of the box body 1 is smaller.

In this embodiment, the hinge shaft 43 has a through hole 44 penetrating in the height direction, and the through hole 44 is penetrating in the radial direction. Therefore, when the hinge shaft 43 cooperates with the shaft sleeve 6 and the shaft hole, it can be better attached to it, thereby eliminating the gap between the hinge shaft 43, the shaft sleeve 6 and the shaft hole, and avoiding the door from shaking.

In this embodiment, the outer door body 3 has an outer door body body 31 and a door shaft portion 32 protruding backward from the outer door body body 31, and the inner door body 2 has a recessed setting and the door shaft portion The recessed part 21 matched with the part 32 and the recessed part 22 recessed along the height direction, the pivot mechanism is arranged in the door shaft part 32 and the recessed part 22 . And the height of the outer door body 31 is higher than the door shaft part 32 and the recessed part 22, thereby effectively hiding the pivot mechanism, preventing users from seeing it directly, improving the integrity of the refrigeration appliance, and further improving the aesthetics.

Moreover, the thickness of the outer door body 3 on the side of the pivot mechanism is greater than the thickness of the inner door body 2 on the side of the pivot mechanism. Therefore, the overall thickness of the door body can be reduced, the cost of the door body can be reduced, and the overall volume of the refrigeration appliance can also be reduced.

As shown in Figures 2 to 4, it is the first embodiment of the extension structure of the present invention. Specifically, the inner door body 2 has an inner door body body 23, and the extension structure is fixed above the inner door body body 23. A connection structure, the connection structure is rotatably connected with the hinge shaft 43 . That is, the inner door body 23 and the connection structure are split structures, which facilitates production and assembly.

The hinge shaft 43 is fixedly connected to the extension part 42, and extends downward to pivotally cooperate with the outer door body 3. The outer door body 3 has a pivot joint part 33 that is rotationally engaged with the hinge shaft 43. The pivot joint The portion 33 is a shaft hole recessed from the outer door body 3 , therefore, the pivot axis of the outer door body 3 is the hinge shaft 43 .

The connecting structure includes a connecting piece 5, one end of the connecting piece 5 is fixed to the inner door body 2, and the other end has a through hole 51 pivotally connected to the hinge shaft 43, therefore, the pivot of the inner door body 2 The rotating shaft is also the hinge shaft 43 . In this embodiment, the connecting member 5 has a flat plate structure and is made of metal, which improves the stability of the connection between the inner door body 2 and the hinge shaft 43 on the one hand, and saves cost and space on the other hand. Of course, in other embodiments, the connecting member 5 may also be a structure extending in the horizontal direction and extending in the height direction, that is, the connecting member 5 is pivotally connected to the hinge shaft 43 not the through hole 51 , but a hollow tubular structure.

The connecting structure also includes a bushing 6 disposed between the hinge shaft 43 and the connecting piece 5, the bushing 6 has a main body portion 61 extending in the front-rear direction, extends downward from the main body portion 61 and is located between the through hole 51 and the hinge Shaft portion 62 between shafts 43 . The shaft sleeve 6 is made of plastic, while the hinge 4 and the connecting piece 5 are made of metal. Moreover, the main body 61 and the connecting piece 5 are jointly fixed on the inner door body 23 to prevent the shaft sleeve 6 from being in an active state. Of course, in other embodiments, the bushing 6 can also be a hollow tubular structure, and it only needs 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 piece 5 are separated by the shaft sleeve 6, avoiding direct contact between the hinge 4 and the connecting piece 5, thereby reducing the noise generated during rotation.

From another point of view, it is also possible to only arrange the shaft sleeve 6 to cooperate with the hinge shaft 43, then the connecting member 5 is used to strengthen the structure. In other words, the shaft sleeve 6 can also be regarded as the connecting piece 5, and the connecting piece 5 can be regarded as the reinforcing piece.

In this embodiment, the bottom of the inner door body 2 and the outer door body 3 also has a rotating shaft and a shaft hole that cooperate with each other, and the inner door body 2 and the outer door body 3 can be assembled together first, and then jointly with the box body 1 installation, the specific process is:

The assembly of the inner door body 2 and the outer door body 3 can be completed through the above steps.

As shown in Fig. 5 to Fig. 10, it is the second embodiment of the extension structure of the present invention, which is different from the first embodiment in that: the extension structure is formed by extending from the inner door body 23 to the outer door body 3 and It is rotatably connected with the shaft hole, that is, the extension structure and the inner door body 23 are integrally structured.

Specifically, the extension structure has a first groove 7 that is recessed downwards to fit in rotation with the hinge shaft 43. Therefore, the pivot shaft of the inner door body 2 is the hinge shaft 43, and the outer door The pivot axis of the body 3 is the extension structure.

Since the inner door body 2 and the outer door body 3 are mainly made of plastic material, in order to reduce the risk of damage caused by the long-term rotation of the extension structure and the shaft hole, the pivot structure also includes a base shaft 8 arranged in the shaft hole. The extension structure has a second groove (not shown) that is recessed upward to rotate with the base shaft 8 . Wherein, the base shaft 8 is a metal piece, that is, the extension structure is rotationally connected with the base shaft 8, thereby preventing the extension structure from squeezing the inner wall of the shaft hole, reducing the risk of damage to the outer door body 3, and improving the inner door body 2. Reliability of the rotary connection with the outer door body 3.

In this embodiment, the first groove 7 and the second groove communicate with each other in the height direction, so the extension structure is easier to form. Specifically, when the extension structure is formed, the mold only needs to be equipped with one component to form the through hole 51, and when the first groove 7 and the second groove are not connected, two components need to be set to form the first groove 7 respectively. and the second groove, of course, in other embodiments, the first groove 7 and the second groove can also be arranged in a non-communicative manner, or the hinge shaft 43 can also be rotatably engaged with the base shaft 8, at this time , the pivot axis of the outer door body 3 is the hinge axis 43, therefore, the pivot axis of the outer door body 3 can be an extension structure or the hinge axis 43 under different circumstances.

Further, in order to facilitate the mutual assembly of the inner door body 2 and the outer door body 3, the pivot structure also includes an elastic member (not shown) arranged below the base shaft 8, and the outer door body 3 has a detachable Then, in order to press down the detachment part 34 of the base shaft 8 . When installing the inner door body 2 and the outer door body 3, the specific process is:

First, remove the dismounting part 34 of the outer door body 3 first; second, align and install the shafts and shaft holes below the inner door body 2 and the outer door body 3; third, align the base shaft 8 Press down so that the top of the base shaft 8 is lower than the bottom of the extension structure; fourth, move the extension structure of the inner door body 2 horizontally above the base shaft 8 and release the base shaft 8 so that the base shaft 8 is pivotally connected to the second Inside the groove, fifth, install the dismounting part 34 . The assembly of the inner door body 2 and the outer door body 3 can be completed through the above steps.

Of course, in other embodiments, the detachment part 34 may not be provided, and the extension structure may be directly installed in the shaft hole of the outer door body 3 through plastic deformation.

Both the first embodiment and the second embodiment of the above-mentioned extension structure can make the inner door body 2 and the outer door body 3 be assembled together first, and then jointly assembled with the box body 1 . This simplifies the assembly steps and improves the assembly efficiency, especially when the refrigeration appliance is taller, even higher than the height of the general staff, so first install the inner door body 2, and then install the outer door body 3, due to the poor viewing angle , is not conducive to installation. 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 differs from the first embodiment in that: the connecting member 5 may also have a rotating shaft, and the rotating shaft extends upwards beyond the hinge 4, and extend into the through hole 44 of the hinge shaft 43 from top to bottom to be pivotally connected with the hinge shaft 43.
