[0030] The present utility model will be further described below in conjunction with the accompanying drawings.
[0031] The hinge structure of the built-in refrigerator of the present utility model is installed on the upper surface and the lower surface of the refrigerator body 1, and it includes a hinge main body 2. On one side surface of the hinge main body 2, a hinge guide shaft 3 and a hinge rotation shaft 4 which are spaced apart are convexly formed. On one side wall of the hinge rotation shaft 4, a stop portion 5 is connected. The height of the stop portion 5 is lower than the height of the hinge rotation shaft 4. The stop portion 5 includes a connection portion 50 connected to the outer side wall of the hinge rotation shaft 4 and an extension portion 51 connected to the connection portion 50 and extending around the hinge rotation shaft 4. A hinge limit groove 6 is formed at an interval between the extension portion 51 and the hinge rotation shaft 4.
[0032] The refrigerator door body 7 and the refrigerator body 1 are installed together. At positions on the upper surface and the lower surface of the refrigerator door body 7 opposite to the hinge guide shaft 3, a door guide groove 70 for the hinge guide shaft 3 to slide therein is recessed. One end of the door guide groove 70 extends to the side wall of the refrigerator door body 7. At a position on one side of the door guide groove 70 and opposite to the hinge rotation shaft 4, a door rotation shaft groove 71 for the hinge rotation shaft 4 to slide therein is recessed. At positions on the upper surface and the lower surface of the refrigerator door body 7 and at one end of the door rotation shaft groove 71, a door limit block 72 capable of moving in the hinge limit groove 6 is convexly formed. The height of the door limit block 72 is the same as that of the stop portion 5.
[0033] The working principle of the hinge structure of the built-in refrigerator of the present utility model is as follows:
[0034] When the refrigerator door body 7 and the refrigerator body 1 are in the closed state, the hinge guide shaft 3 is located at one end of the door guide groove 70 far from the side wall of the refrigerator door body 7. The hinge rotation shaft 4 is located at one end of the door rotation shaft groove 71 close to the end far from the door limit block.
[0035] When the refrigerator door body 7 rotates 15° to open the door, the hinge guide shaft 3 is fixed, the end of the door guide groove 70 far from the side wall gradually moves away from the hinge guide shaft 3, and the door limit block 72 approaches the hinge rotation shaft 4.
[0036] When the refrigerator door body 7 rotates 25° during door opening, the end of the door guide groove 70 away from the side wall continues to move away from the hinge guide shaft 3, and the door limit block 72 continues to approach the hinge rotation shaft 4. At this time, the door limit block 72 is about to enter the hinge limit groove 6. At this moment, the door limit block 72 semi-wraps the hinge rotation shaft 4. When continuing to open the door, the door will rotate around the hinge rotation shaft 4.
[0037] When the refrigerator door body 7 rotates 45° during door opening, the end of the door guide groove 70 away from the side wall continues to move away from the hinge guide shaft 3, and the door limit block 72 is inserted into the hinge limit groove 6. At this time, the door limit block 72 semi-wraps the hinge rotation shaft 4. When continuing to open the door, the door will rotate around the hinge rotation shaft 4.
[0038] When the refrigerator door body 7 rotates 90° during door opening, the end of the door guide groove 70 located on the side wall is adjacent to the hinge guide shaft 3, and the door limit block 72 is inserted into the hinge limit groove 6. At this time, the door limit block 72 semi-wraps the hinge rotation shaft 4. When continuing to open the door, the door will rotate around the hinge rotation shaft 4.
[0039] When the refrigerator door body 7 rotates 105° during door opening, the hinge guide shaft 3 disengages from the door guide groove 70, and the door limit block 72 is fully embedded in the hinge limit groove 6. The door can rotate around the hinge rotation shaft 4 without loosening.
[0040] For the embedded refrigerator hinge structure of the present utility model, the refrigerator door body can perform a rotational movement under the limitation of the hinge and the structure of the refrigerator door body itself. During the rotation process, the outer side wall of the refrigerator door body never exceeds the outer side wall boundary of the refrigerator cabinet, enabling the refrigerator door body to open with a 0-side gap and realizing a 0-side gap embedding of the refrigerator.
[0041] What is listed in the present utility model is an embodiment in which the hinge structure is applied to a refrigerator. As a further improvement of the embodiment of the present utility model, the hinge structure can also be applied to other electrical appliances that require an up-and-down flipping door, such as ovens, microwave ovens, etc., which will not be elaborated here.
[0042] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be regarded as the protection scope of the present utility model.
