DETAILED DESCRIPTION

[0028] The application will be further described below in combination with the drawings and embodiments.

[0029] The directions involved in the specification are all based on the directions shown in the drawings and only represent relative positional relationships, not absolute positional relationships.

[0030] As Figure 1As shown in the drawings, a refrigerator comprises a cabinet 1 and a door body 2, and an arc shaft embedded refrigerator hinge is installed between the cabinet 1 and the door body 2. The arc shaft embedded refrigerator hinge is installed on one side of the cabinet 1 and the door body 2, and the door body 2 can be rotated to open around the arc shaft embedded refrigerator hinge. The inner side of the door body 2 is provided with a door seal mounting groove 21 on the side adjacent to the cabinet 1, for mounting a door seal.

[0031] As shown in the drawings, Figure 2 and Figure 3 As shown in the drawings, an arc shaft embedded refrigerator hinge comprises a hinge shaft body 3 and a hinge seat body. The hinge shaft body 3 is in a rectangular structure, and one side of the hinge shaft body 3 is provided with a stepped surface. An upper layer 301 of the stepped surface is fixedly installed on the cabinet 1, and an arc shaft 31 and a guide circular shaft 32 are provided on a lower layer 302 of the stepped surface. The arc shaft 31 and the guide circular shaft 32 are arranged in an upper-lower manner, that is, the arc shaft 31 is fixed on the lower layer 302 of the stepped surface, and the guide circular shaft 32 is fixed on the arc shaft 31. The arc shaft 31 comprises a left circular arc surface 311 and a right circular arc surface 312, and the left circular arc surface 311 and the right circular arc surface 312 are connected by a large circular arc surface 313 and a small circular arc surface 314. The left circular arc surface 311, the large circular arc surface 313, the right circular arc surface 312 and the small circular arc surface 314 form an arc waist-shaped block. The axis of the guide circular shaft 32 is concentric with the axis of the right circular arc surface 312, and the guide circular shaft 32 is in a cylindrical shape. In this embodiment, the diameter of the guide circular shaft 32 is smaller than the diameter of the right circular arc surface 312, and in actual application, the diameter of the guide circular shaft 32 can be equal to or greater than the diameter of the right circular arc surface 312, which is not limited in this embodiment.

[0032] As shown in the drawings, Figure 4 and Figure 5 As shown in the drawings, the door body 2 is provided with a hinge seat body, and an axle hole is formed in the hinge seat body. The hinge seat body can be a simple component and is fixedly installed on the top of the door body 2 to work with the arc shaft 31 and the guide circular shaft 32, or a hole can be punched directly above the door body 2 to work with the arc shaft 31 and the guide circular shaft 32.

[0033] The shaft hole comprises an upper shaft hole 23 and a lower shaft hole 24. The upper shaft hole 23 is provided with an upper arc-shaped shaft hole 231 for guiding the arc-shaped shaft 31 from an initial position to a first opening angle point, a rotating shaft hole 232 for guiding the arc-shaped shaft 31 from the first opening angle point to a second opening angle point and then to a third opening angle point, and the arc-shaped shaft 31 is limited to slide in the upper shaft hole 23. The upper arc-shaped shaft hole 231 is shaped to be similar to the arc-shaped shaft 31, and the arc-shaped position at one end thereof is communicated with the rotating shaft hole 232. The rotating shaft hole 232 comprises an upper guiding flange 2321, an upper limiting flange 2322 and an upper supporting flange 2323. The upper guiding flange 2321, the upper limiting flange 2322 and the upper supporting flange 2323 are connected through an arc transition, so as to form a triangular structure, and the upper arc-shaped shaft hole 231 is communicated with the intersection position of the upper guiding flange 2321 and the upper supporting flange 2323.

[0034] The lower shaft hole 24 is provided with a first guiding shaft hole 241 and a second guiding shaft hole 242 for assisting the arc-shaped shaft 31 to run between each opening angle point in the upper shaft hole 23. The first guiding shaft hole 241 and the second guiding shaft hole 242 are located at the bottom of the rotating shaft hole 232. The first guiding shaft hole 241 and the second guiding shaft hole 242 are communicated at a certain angle, and the outer end portions of the first guiding shaft hole 241 and the second guiding shaft hole 242 are arc surfaces, and the connection positions thereof are arc transition connections. The hole widths of the first guiding shaft hole 241 and the second guiding shaft hole 242 are the same as those of the guiding circular shaft 32, and the guiding circular shaft 32 can be limited to slide in the first guiding shaft hole 241 and the second guiding shaft hole 242.

[0035] Embodiment one:

[0036] The positional relationship between the upper shaft hole 23 and the lower shaft hole 24 is determined.

[0037] As Figure 6The diagram shows the door in its initial state, where door 2 and housing 1 are closed. The limit line extending beyond housing 1 is L1. For the embedded door 2, the limit line L1 must extend less than or equal to 3mm beyond housing 1. The outer edge positioning line of the door seal is L2. To prevent the door seal from being caught, the arc axis center O1 of the arc-shaped shaft 31 is located on the outer edge positioning line L2 of the door seal. A first positioning circle 4 is drawn with the arc axis center O1 as its center. The first positioning circle 4 is tangent to the vertex M of door 2 and located to the left of the limit line L1. The transition from the initial state to the first opening angle point is the first step of the door opening process. Rotating the door opening process with the arc axis center O1 satisfies the embedding condition. The arc axis center O1 is the axis of the arc axis 31, i.e., the location of the center of the arc of the arc axis 31. The left arc surface axis center O2 of the left arc surface 311 and the right arc surface axis center O3 of the right arc surface 312 are located on the first positioning circle 4. The arc-shaped shaft 31 is located within the upper arc-shaped shaft hole 231, and the two are concentric, with the center of the circle being the arc-shaped shaft axis O1. The guide shaft 32 rests on the leftmost side of the first guide shaft hole 241. The first step of the door opening process involves rotation around the arc-shaped shaft axis O1. The upper arc-shaped shaft hole 231 serves as the rotation guide structure. The arc-shaped shaft 31 rotates out from the upper arc-shaped shaft hole 231, and the guide shaft 32 rotates along the first guide shaft hole 241, coordinating with the rotation of the door body 2 to complete the first step of the door opening process.

[0038] like Figure 5 and Figure 7 As shown in the joint, Figure 7 This is a schematic diagram showing the positions of the hinge shaft body and hinge seat body at the first opening angle point, i.e., a schematic diagram showing the positional relationship between the door body 2 and the box body 1 after the first opening process. At this time, the arc-shaped shaft 31 has completely slid out of the upper arc-shaped shaft hole 231, the right arc surface 312 abuts against the upper limiting flange 2322, the left arc surface 311 is located at the exit position of the upper arc-shaped shaft hole 231, and the guide shaft 32 is exactly located at the junction of the first guide shaft hole 241 and the second guide shaft hole 242. The transition from the first opening angle point to the second opening angle point is the second opening process. In the second opening process, the second positioning circle 5 is drawn with the left arc surface axis 02. The second positioning circle 5 is tangent to the vertex M of the door body 2 and is located to the left of the limiting line L1. Rotating the opening process with the left arc surface axis 02 can satisfy the embedding condition; thus, the position of the left arc surface axis 02 is determined. In the second step of the door opening process, the second guide shaft hole 242 limits the sliding of the guide shaft 32, causing the door to rotate around the left arc surface axis 02. The second guide shaft hole 242 finally enters the end of the second guide shaft hole 242, and the upper limiting flange 2322 limits the arc-shaped shaft 31. The left arc surface 311 is still located at the exit position of the upper arc-shaped shaft hole 231. The right arc surface 312 of the arc-shaped shaft 31 slides into the transition position between the upper limiting flange 2322 and the upper support flange 2323, thus reaching the desired position. Figure 8 At the location shown, as Figure 8The second opening and closing angle point hinge shaft body and hinge seat body position diagram, that is, the position relationship between the door body 2 and the cabinet 1 after the second step of the door opening process is completed.

[0039] As shown in Figure 9 , the transition from the second opening and closing angle point to the third opening and closing angle point is the third step of the door opening process. The third positioning circle 6 is drawn with the right circular arc surface axis center O3 as the center, the third positioning circle 6 is tangent to the vertex M of the door body 2 and located on the left side of the limiting line L1, and the right circular arc surface axis center O3 rotation opening process can meet the embedded condition; the arc-shaped shaft 31 rotates clockwise with the right circular arc surface axis center O3 as the axis. In order to meet the condition that when the door is opened by 90 degrees, the door body 2 exceeds the cabinet 1 within the limiting line L1 and the door body 2 is at least flush with the cabinet 1, that is, the distance L3 from the right circular arc surface axis center O3 to the extension line of the cabinet is less than or equal to the distance L4 from the right circular arc surface axis center O3 to the outer edge of the door body (L3≤L4), that is, the position of the right circular arc surface axis center O3 can be determined. After the third step of the door opening process is completed, the guide circle shaft 32 is located at the end of the second guide shaft hole 242, the right circular arc surface 312 is located at the transition position between the upper limiting flange 2322 and the upper supporting flange 2323, and the guide circle shaft 32 is the center of the right circular arc surface 312.

[0040] As shown in Figure 10 , as a refrigerator that does not need to be embedded, the door is opened by 90 degrees and then continues to be opened. The transition from the third opening and closing angle point to the fourth opening and closing angle point is the fourth step of the door opening process. The arc-shaped shaft 31 rotates clockwise with the right circular arc surface axis center O3 as the axis in the third step of the door opening process, and rotates to the set opening angle. The arc-shaped shaft 31 and the rotation shaft hole 232 cooperate with the limiting position at this time. At this time, the large circular arc surface 313 is in contact with the upper limiting flange 2322, and the door body 2 stops rotating under the limitation of the upper limiting flange 2322, and the opening process is completed. The fourth step of the door opening is not limited to rotating the door with the right circular arc surface axis center O3 as the axis, but can also rotate the door with the left circular arc surface axis center O2 as the axis.

[0041] The refrigerator door is closed in the opposite direction of the refrigerator door opening process steps, and the components interact with each other.

[0042] Example Two:

[0043] This example is basically the same as example one, the only difference is that in the first step of the door opening process, the first opening and closing angle point is that the arc-shaped shaft 31 is not completely slid out of the upper arc-shaped shaft hole 231, so that the first opening angle in example two is smaller than the first opening angle in example one. Because the first opening angle in example two is reduced, the first guide shaft hole 241 and the second guide shaft hole 242 on the door body 2 are as shown in Figure 11 ;

[0044] As shown in Figure 12As shown, the first opening and closing angle point position relation diagram in the second embodiment is shown, in order to ensure that the right circular surface axis O3 smoothly enters the end of the second guide shaft hole 242 in the second step opening process, so the rotating axis O4 is set, the right circular surface axis O3 and the end circular surface axis of the second guide shaft hole 242 are on a circle with the rotating axis O4 as the center, the fourth positioning circle 7 is drawn with the rotating axis O4 as the center, the fourth positioning circle 7 is tangent to the top point M of the door body 2 and is located on the left side of the limiting line L1, so that the second step rotating process with the rotating axis O4 as the axis in the second embodiment meets the embedding condition. In the second step opening process in the second embodiment, the upper support flange 2323 supports the arc-shaped shaft 31, and the guide circular shaft 32 is guided in the second guide shaft hole 242 of the second embodiment, so as to make the door body 2 rotate with the rotating axis O4 as the center, and the second step opening process is completed.

[0045] The arc-shaped shaft embedded refrigerator hinge and the refrigerator solve the technical problem of high production cost of the embedded refrigerator hinge in the prior art, and the arc-shaped shaft embedded refrigerator hinge with an irregular structure is arranged, so that low-cost embedding is realized, and customer demand is met.

[0046] The present application is not limited to the above specific embodiments, and those skilled in the art can make various modifications without creative labor, and all the modifications fall within the protection scope of the present application.
