[0002] This invention belongs to the technical field of household refrigerators, and particularly relates to a refrigerator. Background Technology

[0003] Currently, refrigerator doors are connected to the refrigerator body via hinges, mostly using a single fixed-axis hinge connection. The door rotates around the fixed axis of the hinge to open or close. However, with the current hinge rotation structure, during the opening process, the angled portion formed by the side wall near the hinge and the front wall of the door moves out of the extended line of the side wall of the refrigerator body near the hinge. For built-in refrigerators or refrigerators with small gaps between the refrigerator exterior and the wall, this hinge design limits the opening angle of the refrigerator door, preventing it from opening completely.

[0039] A refrigerator 1, such as Figures 1-10 As shown, it includes a box 10 defining an insulated storage compartment 11; the box 10 includes an outer shell 12 and an inner liner 13; wherein the inner liner 13 encloses the storage compartment 11 with an opening 14 on one side. A front end face 15 is formed on the box 10 surrounding the opening end of the storage compartment 11. A door 2 is provided on the box 10 to open or close the storage compartment 11.

[0040] In this embodiment, the door body 2 is rotatably connected to the housing 10 via a door hinge 3. Specifically, the door hinge 3 includes a door hinge plate 30, and the door hinge plate 30 has a first fixed shaft 31 and a second fixed shaft 32 on the side near the door body 2. In this embodiment, the first fixed shaft 31 and the second fixed shaft 32 are arranged side by side, and both the first fixed shaft 31 and the second fixed shaft 32 are perpendicular to the door hinge plate 30.

[0041] The housing 10 includes a first side wall 10a that is vertically arranged near the door hinge 3 and a second side wall 10b that is arranged opposite to the first side wall 10a. The first fixing shaft 31 is located on the side of the second fixing shaft 32 near the second side wall 10b.

[0042] The door 2 has a front wall 21 away from the housing and a rear wall 22 close to the housing when the door 2 is closed, and a side wall 23 close to the door hinge 3 and connecting the corresponding ends of the front wall 21 and the rear wall 22. The side wall 23 and the front wall 21 form an angle 24, and the side wall 23 and the front wall 21 intersect to form a first edge line L1, and the side wall 23 and the rear wall 22 intersect to form a second edge line L2.

[0043] The door body 2 is provided with a single track groove 4, and the first fixed shaft 31 and the second fixed shaft 32 of the door hinge 3 are both installed in the single track groove 4. The single track groove 4 has a first extreme position A and a second extreme position B; the first fixed shaft 31 and the second fixed shaft 32 reciprocate between the first extreme position A and the second extreme position B of the single track groove 4. The first extreme position A is located on the side of the second extreme position B closer to the rear wall 22 of the door, and the first extreme position A is located on the side of the second extreme position B away from the side wall 23 of the door.

[0044] The single rail groove 4 connects the first extreme position A and the second extreme position B, and protrudes towards the direction of the second ridge line L2.

[0045] Specifically, such as Figure 4 As shown, the single-track groove 4 includes a first groove segment 41 and a second groove segment 42 that are connected. The first groove segment 41 extends from a first extreme position A toward the side wall 23 of the door; the second groove segment 42 extends from a second extreme position B toward the rear wall 22 of the door, and the end of the second groove segment 42 near the rear wall 22 is connected to the end of the first groove segment 41 near the side wall 23 of the door. The first groove segment 41 and the second groove segment 42 are smoothly connected. The connection point between the first groove segment 41 and the second groove segment 42 is denoted as the inflection point C.

[0046] The first fixed shaft 31 and the second fixed shaft 32 are installed simultaneously in the monorail groove 4.

[0047] When door 2 is closed, such as Figures 5-6 As shown, the first fixed shaft 31 is located at the first extreme position A of the single track groove 4, and the second fixed shaft 32 is located at the inflection point C; that is, the second fixed shaft 32 is located at the connection between the first groove segment 41 and the second groove segment 42. At this time, the door side wall 23 of the door body 2 is coplanar with the first body side wall 10a of the box body 10.

[0048] When door 2 is opened, as follows Figures 7-8As shown, the first fixed shaft 31 and the second fixed shaft 32 move relative to each other along the single track groove 4. As the door body 2 rotates, the second fixed shaft 32 enters the first groove section 41, and the first fixed shaft 31 moves from the first extreme position A to the second extreme position B.

[0049] When door 2 is opened to its limit position, such as Figures 9-10 As shown, the second fixed shaft 32 is located at the second limit position B of the single track groove 4, and the first fixed shaft 31 is located within the second groove section 42 of the single track groove 4. During the entire process of opening the door 2, the door 2 rotates and opens in a direction away from the opening 14 of the storage compartment 11; simultaneously, the door 2 moves towards the side of the second body sidewall 10b of the cabinet 10, thereby effectively limiting the distance between the first ridge line L1 on the door 2 and the first body sidewall 10a during the opening process, denoted as D0. In this embodiment, D0 < 5mm during the opening process of the door 2. When the door 2 of the refrigerator 1 of the present invention is opened, it moves a certain distance towards the side away from the door hinge 3 (the second body sidewall 10b), thereby preventing the door sidewall 23 of the door 2 from protruding and affecting the opening of the door 2.

[0050] In this embodiment, when the door 2 is opened to its limit position, the door side wall 23 of the door 2 is parallel to the front end face 15 of the box 10, and the door 2 is fully opened.

[0051] In this embodiment, the thickness of the door body 2 is small, and the thickness of the door body 2 is W. The minimum thickness of the door body is denoted as W. min W min ∈[43, 53], unit: mm. In this embodiment, the front wall 21 is set as an arc, and the thickness of the door body 2 is minimal at the connection between the front wall 21 and the side wall 23. The diameters of the first fixed shaft 31 and the second fixed shaft 32 are both d, d∈[6.5, 7.5], unit: mm.

[0052] When door 2 is closed, the rear wall 22 of the door and the front face 15 of the box 10 are sealed by a door seal to form a sealed storage compartment 11. The distance between the rear wall 22 of the door and the front face 15 of the box 10 when door 2 is closed is denoted as D1, where D1 ∈ [9.5, 11.5], in mm. Both the first fixed shaft 31 and the second fixed shaft 32 are connected to the door hinge plate 30 by riveting.

[0053] Both the upper and lower ends of the door body 2 are provided with single track grooves 4, and the top of the box body 10 and the lower part of the storage room 11 are provided with door hinges 3 at positions corresponding to the lower end of the door body 2; wherein, the door hinges 3 that cooperate with the lower end of the door body 2 are formed by stamping, and the thickness of its door hinge plate 30 is H, H∈[4,8], unit: mm.

[0054] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
