Description

Technical Field

[0001] The utility model belongs to the technical field of refrigerators, and particularly relates to a left - and - right opening structure and a refrigerator. Background Technique

[0002] At present, refrigerators on the market generally have a left - and - right opening structure. The purpose is to solve the problem that when the door is opened and blocked by the side wall in real life, by moving the hinge position of the refrigerator, the refrigerator door can be opened to the left or right to meet different usage requirements of the refrigerator. However, the existing general method is to move the hinge position of the refrigerator to meet the requirements. At this time, the hinge needs to be disassembled and then assembled on the other side. The operation is complex, and it is difficult for users with poor manual ability to operate. Moreover, there is a possibility of damaging the refrigerator during the operation, resulting in poor user experience.

[0003] Therefore, the patent application No. 202223297364.X discloses a refrigerator with left - and - right opening, including a door body hinged to the refrigerator cabinet. A hinge shaft is provided at the hinge of the door body and the refrigerator cabinet. The door body includes door handles rotatably arranged on the left and right sides of the door body. A linkage rod is provided at the rotation position of the door body and each door handle. An elastically movable locking member is provided on the door body corresponding to each linkage rod. The locking member and the corresponding hinge shaft are adjacently arranged in a split - type manner, and an axial limiting portion is provided between them. The hinge shaft is locked on the axial limiting portion when the door body is closed. A guiding portion for triggering the movement of the locking member is provided between each linkage rod and the locking member. When the left or right door handle is driven by an external force to rotate the corresponding linkage rod, the linkage rod drives the corresponding locking member to move through the guiding portion, so that the left or right hinge shaft is disengaged from the axial limiting portion of the locking member, and the hinge shaft on the left end or right end of the door body is unlocked, realizing the left - hand or right - hand opening of the door body; or, the hinge shaft and the locking member are set as a whole. When the door body is in the closed state, one end of the locking member acts on one end of the linkage rod to block the rotation of the linkage rod; when the door body is opened on the left or right side, the linkage rod rotates through the door handle to move the locking member, and one end of the locking member is disengaged from the linkage rod, realizing the unlocking and opening of the door body. This left - and - right opening refrigerator does not require the user to disassemble the hinge of the refrigerator, but its structure is still complex and has structures such as hinge shafts and springs, resulting in high costs.

For the convenience of opening the door from the left or the right, handles 6 are provided on both the left and right sides of the door body 1. The handle 6 can be an external handle 6 or can be configured as a structure similar to an open slot.

[0034] The specific structures of the first rotation module and the first rotational pair mechanism of the present invention will be elaborated in detail below. Since the second rotation module and the first rotation module are symmetrically arranged up and down, the third rotation module and the fourth rotation module are symmetrically arranged up and down, and the left rotation module and the right rotation module are symmetrically arranged left and right (that is, the first rotation module and the third rotation module are symmetrically arranged left and right), the specific structures of the second rotation module, the third rotation module, and the fourth rotation module are not described in detail in the present invention. Similarly, the second rotational pair mechanism and the first rotational pair mechanism are symmetrically arranged up and down, the third rotational pair mechanism and the first rotational pair mechanism are symmetrically arranged left and right, and the fourth rotational pair mechanism and the third rotational pair mechanism are symmetrically arranged up and down. Therefore, the specific structures of the second rotational pair mechanism, the third rotational pair mechanism, and the fourth rotational pair mechanism are not described in detail in the present invention either;

[0035] Specifically, the first rotation module of the present utility model includes a first guide rail 71, a second guide rail 72, a third guide rail 73, a first limiting portion 74, and a second limiting portion 75. Both the first guide rail 71 and the third guide rail 73 are provided at the left part of the top surface of the door body 1, and the third guide rail 73 is located on the right side of the first guide rail 71. There is a first opening at the rear side of the first guide rail 71, and a first positioning groove 711 is provided at the front side of the left part of the first guide rail 71. The second guide rail 72 is located below the first guide rail 71, and the top surface of the second guide rail 72 is flush with the bottom surface of the first guide rail 71. The first limiting portion 74 is provided on the left side inside the second guide rail 72, and the top surface of the first limiting portion 74 is flush with the bottom surface of the first guide rail 71. There is a second opening 721 extending backward on the right side of the first limiting portion 74 inside the second guide rail 72, and a second positioning groove 722 is provided at the left part inside the second guide rail 72. The groove wall of the first positioning groove 711 is in the shape of a superior arc (specifically, the horizontal cross-section is in the shape of a superior arc), and the groove wall of the second positioning groove 722 is in the shape of a semi-circle (specifically, the horizontal cross-section is in the shape of a semi-circle). The second limiting portion 75 is provided at the rear part inside the third guide rail 73. The rear side of the third guide rail 73 is open, and the second limiting portion 75 divides the rear opening of the third guide rail 73 into a third opening 732 and a fourth opening 733 left and right;

[0036] The first rotation pair mechanism of the present utility model includes a first main shaft 81, a first sub-shaft 82, and a first reset guide bar 83. The height of the first sub-shaft 82 is greater than the height of the first main shaft 81. The first main shaft 81 is inserted into the first guide rail 71, the first sub-shaft 82 is inserted into the second guide rail 72, the first limiting portion 74 is used to limit the first sub-shaft 82, and the first reset guide bar 83 is inserted in front of the second limiting portion 75 inside the third guide rail 73.

[0037] The opening and closing action principles of the present utility model will be elaborated in detail below:

[0038] It can be understood that in the present utility model, the first main shaft 81 is inserted into the first guide rail 71 and moves inside the first guide rail 71. When the first main shaft 81 moves to one side, it moves out of the first guide rail 71 through the first opening. When the first main shaft 81 moves to the other side, it moves to the first positioning groove 711 and stops, and rotates along the first positioning groove 711 with a groove wall in the shape of a superior arc. The first sub-shaft 82 is inserted into the second guide rail 72 and moves inside the second guide rail 72. When the first sub-shaft 82 moves to one side, it moves out of the second guide rail 72 through the second opening 721. When the first sub-shaft 82 moves to the other side, it moves to the second positioning groove 722 and stops, and rotates along the second positioning groove 722 with a groove wall in the shape of a semi-circle. The first reset guide bar 83 is inserted in front of the second limiting portion 75 inside the third guide rail 73. When the first reset guide bar 83 moves to one side, it moves out of the third guide rail 73 through the third opening 732. When the first reset guide bar 83 moves to the other side, it moves out of the third guide rail 73 through the fourth opening 733.

[0039] When in the closed state, the left and right handles 6 are simultaneously stressed. That is, when pulling the left and right handles 6 forward, the first main shafts 81 and the first reset guide bars 83 of the first rotation module, the second rotation module, the third rotation module, and the fourth rotation module (the components of the first rotation module, the second rotation module, the third rotation module, and the fourth rotation module are the same except for the symmetry relationship) will respectively fit against the first guide rail 71 and the third guide rail 73. Due to the limitation of the first guide rail 71 and the third guide rail 73, the door body 1 will not fall off;

[0040] When the door is pulled from the right, the third rotating pair mechanism and the fourth rotating pair mechanism separate from the third rotating module and the fourth rotating module respectively. Specifically, the first reset guide bar 83 of the third rotating pair mechanism and the fourth rotating pair mechanism leaves the third guide rail 73 of the third rotating pair mechanism and the fourth rotating pair mechanism through the fourth opening 733 of the third rotating module and the fourth rotating module respectively. The first main shaft 81 of the third rotating pair mechanism and the fourth rotating pair mechanism leaves the first guide rail 71 of the third rotating module and the fourth rotating module through the first opening of the third rotating module and the fourth rotating module. The first secondary shaft 82 of the third rotating pair mechanism and the fourth rotating pair mechanism leaves the second guide rail 72 of the third rotating module and the fourth rotating module through the second opening 721 of the third rotating module and the fourth rotating module. At the same time, the first rotating pair mechanism and the second rotating pair mechanism move within the first rotating module and the second rotating module respectively. The first main shaft 81 of the first rotating pair mechanism and the second rotating pair mechanism moves towards the first positioning groove 711 within the first guide rail 71 in the first rotating module and the second rotating module. The first secondary shaft 82 of the first rotating pair mechanism and the second rotating pair mechanism moves towards the second positioning groove 722 within the second guide rail 72 in the first rotating module and the second rotating module. The first reset guide bar 83 of the first rotating pair mechanism and the second rotating pair mechanism moves towards the third opening 732 within the third guide rail 73 in the first rotating module and the second rotating module. When the right handle 6 opens the door body 1 by about 1 degree, at this time, each structure still cooperates with each other. The first main shaft 81, the first secondary shaft 82 and the first reset guide bar 83 move along the corresponding first guide rail 71, second guide rail 72 and third guide rail 73. When the right handle 6 opens the door body 1 to about 13 degrees, the first main shaft 81, the first secondary shaft 82 and the first reset guide bar 83 of the third rotating pair mechanism and the fourth rotating pair mechanism disengage from the third rotating module and the fourth rotating module. When the right handle 6 opens the door body 1 to about 28 degrees, the first main shaft 81, the first secondary shaft 82 and the first reset guide bar 83 of the third rotating pair mechanism and the fourth rotating pair mechanism continue to disengage from the third rotating module and the fourth rotating module. The first main shaft 81 of the first rotating pair mechanism and the second rotating pair mechanism abuts against the first positioning groove 711 and rotates in place within the first positioning groove 711. The first secondary shaft 82 of the first rotating pair mechanism and the second rotating pair mechanism approaches the second positioning groove 722. The first reset guide bar 83 of the first rotating pair mechanism and the second rotating pair mechanism disengages from the first rotating module and the second rotating module through the third opening 732 of the first rotating module and the second rotating module. When the right handle 6 is opened to 90 degrees, the first secondary shaft 82 of the first rotating pair mechanism and the second rotating pair mechanism reaches within the second positioning groove 722. At this time, the door body 1 is opened to the maximum angle. The specific operation process of closing the door and opening the door body 1 from the left is reverse or basically similar to that of opening the door from the right, and will not be elaborated here.

[0041] The present utility model also discloses a refrigerator, including the left and right door opening structure described above.

[0042] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the present utility model. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model all fall within the protection scope of the technical solution of the present utility model.
