[0002] Current RV refrigerators with compartment-within-compartment (also known as ice-temperature compartment) doors are all single-direction, opening to the left or right. Changing the opening direction requires disassembling the entire door, reversing hinges and shafts, or even replacing parts, before reinstallation. This installation method has the following drawbacks: 1. In use, multiple users typically share a single refrigerator, and different users inevitably have different habits, which cannot be adjusted independently, resulting in poor user comfort; 2. If a user needs to change the opening direction, on-site after-sales service is usually required, leading to high service costs. Therefore, improvement is necessary. Summary of the Invention

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] Example

[0031] refer to Figures 1 to 6 A refrigerator door structure for a motorhome refrigerator includes a door body 1, an upper door hinge 2, and a lower door hinge 3. See details. Figure 3 The top surface of door 1 has two symmetrically arranged upper door hinges 11 on both sides, and the bottom surface of door 1 has two symmetrically arranged lower door hinges 12 on both sides. The upper door hinges 11 and lower door hinges 12 are vertically arranged. (See details...) Figure 1 Two upper door hinges 2 are arranged corresponding to the two upper door pivots 11 of the door body 1, and two lower door hinges 3 are arranged corresponding to the two lower door pivots 12 of the door body 1. Two handles 100 are also symmetrically arranged on both sides of the front of the door body 1. The handles 100 are concealed handle structures formed by grooves provided on the front of the door body 1.

[0032] For details, please refer to the following: Figure 6 The upper hinge 2 of the door has an upper hinge seat 21 and an upper hinge shaft located at the front of the upper hinge seat 21, as detailed in the reference. Figure 5 The lower hinge 3 has a lower hinge seat 31 and a lower hinge shaft located at the front of the lower hinge seat 31. Both the upper and lower hinge shafts adopt a hinge shaft portion 32 structure. The hinge shaft portion 32 has a C-shaped semi-annular structure, with a vertically arranged hinge shaft hole 33 in its middle and an elastic side opening 34 on its front side wall. The hinge shaft portion 32 is typically made of plastic, and the C-shaped semi-annular structure provides a certain degree of elasticity to the elastic side opening 34. The hinge shaft holes 33 of the upper hinge 2 and the lower hinge 3 are correspondingly fitted onto the upper door shaft 11 and the lower door shaft 12, respectively. The upper door shaft 11 and the lower door shaft 12 can be inserted into or disengaged from the hinge shaft portion 32 through the elastic side opening 34. (See details...) Figure 11 The upper door hinge 11 and the lower door hinge 12 are both wide at the front and narrow at the back. The upper door hinge 11 and the lower door hinge 12 are inserted into the elastic side opening 34 from the rear and disengaged from the elastic side opening 34 from the front.

[0033] In the above structure, when the door 1 is in the closed state, the two upper hinges 11 and two lower hinges 12 of the door 1 are respectively inserted into the hinge pin holes 33 of the two upper hinges 2 and the two lower hinges 3. When it is necessary to open the door 1 from the left side, the handle 100 on the left side of the door 1 is used to slightly pull the upper hinges 11 and lower hinges 12 on the left side out of the two upper and lower hinge pin holes 33 on the left side through the elastic side opening 34. Then, the handle 100 is pulled slightly to rotate the upper hinges 11 and lower hinges 12 on the right side of the door 1 around the two upper and lower hinge pin holes 33 on the right side, completing the opening operation of the door 1 from the left side. Figure 10As shown. Under the elastic clamping action of the elastic side opening 34, the upper door hinge 11 and lower door hinge 12 on the right side of the door body 1 are not easily disengaged from the hinge hole 33, thus ensuring that the door body 1 opens smoothly. When it is necessary to close the door body 1, push the door slightly in the opposite direction, so that the upper door hinge 11 and lower door hinge 12 on the right side of the door body 1 rotate in the opposite direction around the two hinge holes 33 on the right side. When the upper door hinge 11 and lower door hinge 12 on the left side of the door body 1 are close to the two hinge holes 33 on the left side, apply a little force to insert the upper door hinge 11 and lower door hinge 12 on the left side into the two hinge holes 33 on the left side through the elastic side opening 34, completing the closing operation of the door body 1 from the left side. When it is necessary to open the door from the right side, the operation can be carried out from the right side in the same way.

[0034] In the above structure, the upper door hinge 11 and the lower door hinge 12 adopt a front-wide and rear-narrow structure, which facilitates easy insertion of the upper door hinge 11 and the lower door hinge 12 into the hinge hole 33 from the narrow end during the closing operation, thereby reducing the closing resistance. At the same time, during the opening operation, the wide end of the upper door hinge 11 and the lower door hinge 12 prevents them from easily disengaging from the hinge hole 33, and prevents the entire door body 1 from falling off due to excessive force applied by the user during the opening operation, thus ensuring the stability of the door opening.

[0035] For further details, please refer to [link / reference]. Figure 4 Both the upper door hinge 11 and the lower door hinge 12 are hollow structures with a through hole in the middle, and each has an elastic side notch 10 on its front side wall. The upper door hinge 11 and the lower door hinge 12 are typically made of plastic, and the elastic side notches 10 on their side walls also have a certain degree of elasticity due to the material. During the closing operation, when the narrow ends of the upper door hinge 11 and the lower door hinge 12 are inserted into the hinge hole 33, the upper door hinge 11 and the lower door hinge 12 are squeezed by the hinge hole 33, causing their elastic side notches 10 to narrow accordingly. This reduces the width of the wide ends of the upper door hinge 11 and the lower door hinge 12, ultimately reducing the resistance to the wide ends of the upper door hinge 11 and the lower door hinge 12 inserting into the hinge hole 33, further improving the comfort of the closing operation.

[0036] For further details, please refer to [link / reference]. Figure 2 and Figure 5 The lower hinge seat 31 has a roller seat 35 at its front end near the lower hinge shaft. A rotatable roller 36 is laterally arranged inside the roller seat 35, and the top of the roller 36 provides rolling support to the bottom surface of the door body 1. In the above structure, the rolling support of the roller 36 on the door body 1 further ensures smooth and easy opening and closing of the door.

[0037] refer to Figures 7 to 10A motorhome refrigerator includes a body 4 and a refrigerator door (not shown). The front of the body 4 has an opening and is closed by the refrigerator door. Inside the body 4, there is a U-shaped inner shell formed by two side panels 41, a top panel 42, and a bottom panel 43. The rear of the inner shell is connected to the back of the body 4 to form an inner box 60. The front of the inner box 60 is closed by the inner box door. The inner box door adopts the refrigerator door structure of this embodiment. In the refrigerator door structure, two upper hinges 2 are symmetrically installed on both sides of the front of the top panel 42, and two lower hinges 3 are symmetrically installed on both sides of the front of the bottom panel 43.

[0038] In the above structure, the upper hinge 2 and lower hinge 3 of the door structure can be installed on the housing 4 before the foaming process, and then positioned and installed by the foamed insulation material after the foaming process. For details, please refer to... Figure 6 The upper hinge seat 21 has mounting holes 22 and is fixedly connected to both sides of the front of the top plate portion 42 through the mounting holes 22. The lower hinge 3 can also adopt a structure with mounting holes (not shown in the figure) for installation.

[0039] The door hinge 3 in this embodiment can also adopt the following structure: see details. Figure 5 In the lower hinge 3, the rear part of the lower hinge seat 31 has a plug 37, the plug 37 has a longitudinally arranged elastic baffle 38, the rear end of the elastic baffle 38 is connected to the plug 37, and the front end has a protruding stop head 39. See details. Figure 9 The bottom plate 43 of the housing 4 has a socket 61 corresponding to the plug 37, and the plug 37 is inserted into the socket 61. The bottom plate 43 has a limiting groove 62 corresponding to the stop head 39 of the elastic baffle 38. The stop head 39 of the elastic baffle 38 is locked in the limiting groove 62 so that the lower hinge 3 of the door is fixedly connected to the front of the bottom plate 43.

[0040] In the above structure, an insertion port 61 is reserved on the housing 4. After the housing 4 is foamed and other manufacturing processes are completed, the lower hinge 3 is inserted into the insertion port 61 by the plug 37. When the stop 39 of the elastic stop 39 moves to the limiting groove 62, the stop 39 naturally snaps into the limiting groove 62 to achieve the fixed installation of the lower hinge 3. Then, the plug 37 and the elastic stop 38 of the lower hinge seat 31 cooperate with the insertion port 61 and the limiting groove 62 of the bottom plate part 43 respectively to achieve convenient and quick installation of the lower hinge 3.

[0041] Furthermore, the elastic baffle 38 includes two symmetrically arranged at the top and bottom. The insertion port 61 of the bottom plate 43 has a limiting groove 62 corresponding to the stop head 39 of the upper and lower elastic baffles 38. Thus, through the cooperation of the stop head 39 of the upper and lower elastic baffles 38 with the upper and lower limiting grooves 62, dual positioning is achieved, improving the stability of the door hinge 3 installation.
