[0057] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0058] With the development of society and the gradual improvement of people's quality of life, people's demand for aesthetically pleasing installation of household refrigeration equipment has become increasingly prominent. Embedding refrigeration equipment into cabinets, that is, forming embedded refrigeration equipment to achieve a unified home decoration style, has become popular.

[0059] However, in the related art, embedded refrigeration equipment generally uses a double-axis double-slot hinge to ensure that the door can be opened smoothly, but the double-axis double-slot hinge has a complex structure and occupies a large space.

[0060] Based on the above considerations, the present application proposes a refrigeration device with a compact hinge assembly that occupies little space. While enabling the door of the embedded refrigeration device to open smoothly, the door can be made thinner, thereby increasing the capacity of the refrigeration device.

[0061] Reference below Figures 1-20 A refrigeration device according to an embodiment of the present application is described.

[0062] See also Figure 1 The refrigeration device 1 of the embodiment of the present application includes a main body 11, a door body 12 and a hinge assembly 13.

[0063] First of all, it should be noted that the refrigeration equipment 1 can be embedded in the surrounding environment part, and the surrounding environment part can be a cabinet, a wall or other adjacent electrical appliances, etc., which is not specifically limited here. In the subsequent writing and drawings, the surrounding environment part is taken as the cabinet body of the cabinet as an example.

[0064] The main body 11 is provided with a storage space for accommodating items, and the front side of the main body 11 is provided with an opening connected to the storage space. The door body 12 is installed on the opening side of the main body 11 to cooperate with the main body 11 to seal the storage space and provide a stable storage space for items.

[0065] See also Figure 2-Figure 4 The door body 12 includes a side wall 122 and a front wall 121 that are arranged at an angle. The side of the door body 12 facing away from the main body 11 is the front side, and the front wall 121 of the door body 12 is located on the front side of the door body 12; the side of the door body 12 close to the surrounding environment is the side, and the side wall 122 of the door body 12 is located on the side of the door body 12, and the front wall 121 and the side wall 122 of the door body 12 are connected at an angle. It should be noted that both sides of the door body 12 in the width direction of the single-door refrigerator may be close to the surrounding environment. The side wall 122 in this application specifically refers to the side wall 122 on the side of the door body 12 close to the hinge assembly 13.

[0066] The hinge assembly 13 includes a first hinge member 131 installed on the main body 11 and a second hinge member 132 installed on the door body 12. The first hinge member 131 and the second hinge member 132 rotate in coordination with each other. By installing the two hinge members on the main body 11 and the door body 12 respectively, the door body 12 can rotate relative to the main body 11, thereby realizing the opening and closing of the door body 12.

[0067] A first shaft 1311 and a second shaft 1312 are fixedly provided on the first hinge member 131 . The second hinge member 132 includes a first groove 1321 and a second groove 1322 that are connected to each other. The first shaft 1311 slides in the first groove 1321 , and the second shaft 1312 slides in the second groove 1322 .

[0068] The first hinge member 131 may include a mounting base, which is fixedly mounted on the main body 11, and the first axis 1311 and the second axis 1312 are spaced apart and arranged on the side of the mounting base facing the door body 12, and the second hinge member 132 is arranged on the door body 12, and the second hinge member 132 is provided with a first groove 1321 and a second groove 1322 that are connected to each other. The first groove 1321 and the second groove 1322 that are connected to each other can reduce the distance between the first groove 1321 and the second groove 1322, thereby reducing the space occupied by the second hinge member 132, and the minimum distance between the first axis 1311 and the second groove 1322 and the minimum distance between the second axis 1312 and the first groove 1321 can be smaller, thereby making the arrangement of the entire hinge assembly 13 more compact, thereby facilitating reducing the space occupied by the entire hinge assembly 13.

[0069] During the process of opening or closing the door body 12, the first shaft 1311 slides in the first groove 1321, and the second shaft 1312 slides in the second groove 1322, so as to constrain the movement trajectory of the door body 12, so that the door body 12 has a tendency to move inward, thereby avoiding collision and interference between the door body 12 and the main body 11 or surrounding environmental parts during movement.

[0070] The distance between the first axis 1311 and the front wall 121 is the first front distance, and the distance between the first axis 1311 and the side wall 122 is the first side distance; the distance between the second axis 1312 and the front wall 121 is the second front distance, and the distance between the second axis 1312 and the side wall 122 is the second side distance.

[0071] The first front distance can be the vertical distance from the axis center of the first axis 1311 to the front wall 121, or it can be the minimum distance between the outer peripheral wall of the first axis 1311 and the front wall 121; the second front distance can be the vertical distance from the axis center of the second axis 1312 to the front wall 121, or it can be the minimum distance between the outer peripheral wall of the second axis 1312 and the front wall 121; the first side distance can be the vertical distance from the axis center of the first axis 1311 to the side wall 122, or it can be the minimum distance between the outer peripheral wall of the first axis 1311 and the side wall 122; the second side distance can be the vertical distance from the axis center of the second axis 1312 to the side wall 122, or it can be the minimum distance between the outer peripheral wall of the second axis 1312 and the side wall 122.

[0072] In the process of the door body 12 opening from the closed state to the maximum angle, the first axis 1311 can slide relative to the first groove 1321, and the second axis 1312 can slide relative to the second groove 1322, so that the first front distance gradually changes from greater than the second front distance to the first front distance less than the second front distance; the first side distance gradually changes from less than the second side distance to greater than the second side distance.

[0073] During the process of opening the door body 12, the movement speed of the second shaft 1312 relative to the second slot 1322 is greater than the movement speed of the first shaft 1311 relative to the first slot 1321, so that the first front distance gradually changes from greater than the second front distance to the first front distance less than the second front distance, and the first side distance changes from greater than the second side distance to less than the second side distance, so that the door body 12 can rotate quickly, and at the end stage of movement, the first side distance changes from less than the second side distance to greater than the second side distance, so that the door body 12 can be opened at a large angle.

[0074] According to the refrigeration device 1 of the present application, by setting the first groove 1321 and the second groove 1322 that are interconnected to shorten the distance between the first groove 1321 and the second groove 1322, and reduce the space volume occupied by the first groove 1321 and the second groove 1322, by limiting the changing relationship between the first front distance and the second front distance and the first side distance and the second side distance during the opening of the door body 12, not only can the space occupied by the hinge assembly 13 during the rotation be reduced, which is convenient for the adaptation of the ultra-thin door, but also it is not easy to interfere with the surrounding environment parts, and the door body 12 of the embedded refrigeration device 1 can be opened at a large angle, which is convenient for users to use.

[0075] According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is the fourth angle, the first front distance is equal to the second front distance; when the relative angle between the door body 12 and the main body 11 is the fifth angle, the first side distance is equal to the second side distance; wherein, the fourth angle is smaller than the fifth angle.

[0076] During the process of the door body 12 opening from the closed state to the maximum angle, the door body 12 passes through the fourth angle and the fifth angle in sequence.

[0077] Among them, when the door body 12 is at the fourth angle, the first front distance is equal to the second front distance, that is, when the opening of the door body 12 is less than the fourth angle, the first front distance is greater than the second front distance, and when the opening of the door body 12 is greater than the fourth angle, the first front distance is less than the second front distance.

[0078] When the opening of the door body 12 is at the fifth angle, the first side distance is equal to the second side distance, that is, when the opening of the door body 12 is less than the fifth angle, the first side distance is greater than the second side distance; when the opening of the door body 12 is greater than the fifth angle, the first side distance is less than the second side distance.

[0079] Among them, the fourth angle can be 15°-45°. For example, the fourth angle can be 15°, 20°, 25°, 29.6°, 35°, 40°, 45° or other angles between 15°-45°, and is not specifically limited here.

[0080] Among them, the fifth angle can be 105°-125°. For example, the fifth angle can be 105°, 110°, 115°, 119.6°, 124° or other angles between 105° and 125°, and is not specifically limited here.

[0081] See also Figure 5 and Figure 6 According to some embodiments of the present application, when the door body 12 is in a closed state, the distance A0 between the axis center of the first axis 1311 and the front wall 121 is 10mm-20mm, the distance B0 between the axis center of the first axis 1311 and the side wall 122 is 17mm-27mm, the distance C0 between the axis center of the second axis 1312 and the front wall 121 is 6mm-16mm, and the distance D0 between the axis center of the second axis 1312 and the side wall 122 is 30mm-40mm.

[0082] By limiting the arrangement positions of the first axis 1311 and the second axis 1312 relative to the door body 12 when the door body 12 is in the closed state, the distances between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 are shortened. While the hinge assembly 13 itself has a compact structure, the distances between the hinge assembly 13 and the front wall 121 and the side wall 122 are also shortened. The mating dimensions of the hinge assembly 13 and the door body 12 are more compact, facilitating reduction in the thickness of the door body 12.

[0083] Among them, the distance A0 between the axis center of the first axis 1311 and the front wall 121 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the front wall 121. The value range of A0 is [10mm, 20mm]. For example, A0 can be 10mm, 12mm, 14mm, 16mm, 18mm, 19mm, 19.5mm, 20mm or other values ​​between 10mm-20mm, which are not specifically limited here.

[0084] The distance B0 between the axis center of the first axis 1311 and the side wall 122 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the side wall 122. The value range of B0 is [17mm, 27mm]. For example, B0 can be 17mm, 19mm, 20mm, 20.7mm, 22mm, 24mm, 26mm, 27mm or other values ​​between 17mm-27mm, which are not specifically limited here.

[0085] The distance C0 between the axis center of the second axis 1312 and the front wall 121 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the front wall 121. The value range of C0 is [6mm, 16mm]. For example, C0 can be 6mm, 8mm, 10mm, 11.7mm, 12mm, 14mm, 16mm or other values ​​between 6mm-16mm, which are not specifically limited here.

[0086] The distance D0 between the axis center of the second axis 1312 and the side wall 122 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the side wall 122. The value range of D0 is [30mm, 40mm]. For example, D0 can be 30mm, 32mm, 34mm, 34.5mm, 36mm, 38mm, 40mm or other values ​​between 30mm-40mm, which are not specifically limited here.

[0087] According to the refrigeration equipment 1 of the embodiment of the present application, when the door body 12 is in a closed state, the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is small, that is, the arrangement of the first axis 1311 and the second axis 1312, the first groove 1321 and the second groove 1322 is relatively compact, so that while ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner, meeting the ultra-thin door requirement of the refrigeration equipment 1.

[0088] See also Figure 7 According to some embodiments of the present application, when the door body 12 is in a closed state, the angle α0 between the line connecting the axes of the first axis 1311 and the second axis 1312 and the front wall 121 of the door body 12 is 15°-45°.

[0089] By limiting the angle between the line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 of the door body 12, the movement trajectory of the door body 12 when it starts to rotate from a closed state can be controlled to avoid interference between the door body 12 and the surrounding environment when it is opened.

[0090] When the door body 12 is in a closed state, the angle α0 between the line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 is in the range of [15°, 45°]. For example, α0 can be 15°, 20°, 25°, 29.6°, 35°, 40°, 45° or other angles between 15° and 45°, which are not specifically limited here.

[0091] See also Figure 6 According to some embodiments of the present application, when the door body 12 is in a closed state, the distance W0 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12 is 0-10 mm, and the distance M0 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12 is 5-15 mm.

[0092] By limiting the interval W0 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12, and the interval M0 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12, the spacing between the first axis 1311 and the second axis 1312 is constrained, so that the layout of the first axis 1311 and the second axis 1312 is compacted and the occupied space is reduced.

[0093] Among them, the value range of the interval W0 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12 is [0, 10mm]. For example, W0 can be 0, 1mm, 2mm, 4mm, 6mm, 7.8mm, 8mm, 10mm or other values ​​between 0-10mm, which are not specifically limited here.

[0094] The range of the distance M0 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12 is [5mm, 15mm]. For example, M0 can be 5mm, 7mm, 9mm, 11mm, 13mm, 13.7mm, 15mm or other values ​​between 5-15mm, which are not specifically limited here.

[0095] See also Figure 7 According to some embodiments of the present application, when the door body 12 is opened from a closed state, the angle β0 between the tangent of the first axis 1311 relative to the moving direction of the first slot 1321 and the front wall 121 is 20°-40°, and the angle γ0 between the tangent of the second axis 1312 relative to the moving direction of the second slot 1322 and the front wall 121 is 40°-60°. When the door body 12 is opened from a closed state, the angle θ0 between the tangent of the first axis 1311 relative to the moving direction of the first slot 1321 and the tangent of the second axis 1312 relative to the moving direction of the second slot 1322 is 20°-40°.

[0096] By limiting the angles β0 and γ0 between the tangents of the first axis 1311 and the second axis 1312 relative to the moving direction of the door body 12 and the front wall 121, as well as the angle θ0 between the tangents of the first axis 1311 and the second axis 1312 relative to the moving direction of the door body 12 when the door body 12 is opened from a closed state, the moving trajectory of the door body 12 when it is opened is constrained to avoid interference between the door body 12 and the surrounding environment.

[0097] Among them, the value range of β0 is [20°, 40°]. For example, β0 can be 20°, 22°, 25°, 28.7°, 30°, 32°, 35°, 40° or other values ​​between 20°-40°, and no specific limitation is given here.

[0098] The value range of γ0 is [40°, 60°]. For example, γ0 can be 40°, 42°, 45°, 50°, 52.8°, 55°, 57°, 60° or other values ​​between 40° and 60°, which are not specifically limited here.

[0099] The value range of θ0 is [20°, 40°]. For example, θ0 can be 20°, 22°, 25°, 28.7°, 30°, 32°, 35°, 40° or other values ​​between 20° and 40°, and no specific limitation is given here.

[0100] According to some embodiments of the present application, when the door body 12 is in a closed state, the first shaft 1311 is spaced apart from the end of the first slot 1321 , and / or the second shaft 1312 is spaced apart from the end of the second slot 1322 .

[0101] By spacing at least one of the first axis 1311 and the second axis 1312 from the ends of the corresponding first groove 1321 and the second groove 1322, a certain negative closing angle can be provided when the door body 12 is in a closed state, thereby ensuring the sealing of the door body 12 when it is closed.

[0102] See also Figure 6 and Figure 7 According to some embodiments of the present application, the first end of the first groove 1321 is connected to the second groove 1322, and the first end of the second groove 1322 is spaced apart from the first end of the first groove 1321. When the door body 12 is in a closed state, the first axis 1311 is located at the first end of the first groove 1321, and the second axis 1312 is located at the first end of the second groove 1322.

[0103] It should be noted that the first end of the first groove 1321 and the first end of the second groove 1322 are both starting ends. When the door body 12 is in a closed state, the first axis 1311 is located at the first end of the first groove 1321, and the second axis 1312 is located at the first end of the second groove 1322. The first end of the first groove 1321 is connected to the middle part of the second groove 1322, so that the starting position of the first axis 1311 can be closer to the second groove 1322, making the overall structural layout more compact and optimizing the space occupied by the entire hinge assembly 13.

[0104] See also Figure 6 and Figure 7 According to some embodiments of the present application, the distance between the first end of the first groove 1321 and the first end of the second groove 1322 is smaller than the distance between the axis center of the first shaft 1311 and the axis center of the second shaft 1312 .

[0105] By setting the axial center distance between the first axis 1311 and the second axis 1312 to be larger than the distance between the first end of the first groove 1321 and the first end of the second groove 1322, when the first axis 1311 and the second axis 1312 are in the starting positions, they are respectively located in the first groove 1321 and the second groove 1322. When the door body 12 is closed, the first axis 1311 will not enter the second groove 1322, thereby improving the working stability of the hinge assembly 13.

[0106] See also Figure 4 、 Figure 8 and Figure 9 According to some embodiments of the present application, the side wall 122 intersects with the front wall 121 at the first edge 123. When the first edge 123 is in the first position, the distance A1 between the axis center of the first axis 1311 and the front wall 121 is 13mm-23mm, the distance B1 between the axis center of the first axis 1311 and the side wall 122 is 9mm-19mm, the distance C1 between the axis center of the second axis 1312 and the front wall 121 is 19mm-29mm, and the distance D1 between the axis center of the second axis 1312 and the side wall 122 is 22mm-32mm. The first position indicates the position where the distance between the first edge 123 and the surrounding environmental parts is the smallest.

[0107] The side wall 122 intersects with the front wall 121 at the first edge 123. When the door body 12 is opened from a closed state to 90°, the first edge 123 is the part with the smallest distance between the entire door body 12 and the surrounding environment parts. When the first edge 123 is rotated to the first position, the distance between the first edge 123 and the surrounding environment parts is the smallest, that is, the probability of interference between the door body 12 and the surrounding environment parts is the largest at this position. By limiting the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 at this position, the maximum over-box amount in the process of the door body 12 opening to 90° is controlled. When the distance between the embedded refrigeration equipment 1 and the surrounding environment parts is very small, the door body 12 can also be opened smoothly without interfering with the surrounding environment parts.

[0108] It should be noted that the "over-box amount" refers to the width by which the first edge 123 of the door body 12 extends beyond the side 111 of the main body 11 during the rotation of the door body 12. The over-box amount affects the interference between the door body 12 and the surrounding environment when it is opened. The smaller the over-box amount, the less likely the door body 12 is to interfere with the surrounding environment, and the gap between the embedded refrigeration device 1 and the surrounding environment can be smaller, improving the aesthetics. When the over-box amount is 0, the refrigeration device 1 can achieve zero embedded installation, that is, there is no gap between the refrigeration device 1 and the surrounding environment.

[0109] Moreover, when the first edge 123 is in the first position, the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is relatively small. While the hinge assembly 13 itself has a compact structure, the distance between the hinge assembly 13 and the front wall 121 and the side wall 122 is also relatively small. The matching size of the hinge assembly 13 and the door body 12 is more compact, which facilitates reducing the thickness of the door body 12.

[0110] Among them, the distance A1 between the axis center of the first axis 1311 and the front wall 121 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the front wall 121. The value range of A1 is [13mm, 23mm]. For example, A1 can be 13mm, 15mm, 17mm, 19mm, 20mm, 22mm, 23mm or other values ​​between 13mm-23mm, which is not specifically limited here.

[0111] The distance B1 between the axis center of the first axis 1311 and the side wall 122 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the side wall 122. The value range of B1 is [9mm, 19mm]. For example, B1 can be 9mm, 10.8mm, 13mm, 15mm, 17mm, 18mm, 19mm or other values ​​between 9mm-19mm, which are not specifically limited here.

[0112] The distance C1 between the axis center of the second axis 1312 and the front wall 121 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the front wall 121. The value range of C1 is [19mm, 29mm]. For example, C1 can be 19mm, 21mm, 23mm, 25mm, 27mm, 28.3mm, 29mm or other values ​​between 19mm-29mm, which are not specifically limited here.

[0113] The distance D1 between the axis center of the second axis 1312 and the side wall 122 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the side wall 122. The value range of D1 is [22mm, 32mm]. For example, D1 can be 22mm, 23.6mm, 26mm, 28mm, 30mm, 31mm, 32mm or other values ​​between 22mm-32mm, which are not specifically limited here.

[0114] According to the refrigeration equipment 1 of the embodiment of the present application, the first groove 1321 and the second groove 1322 are arranged to be connected to each other, so as to shorten the distance between the first groove 1321 and the second groove 1322 and reduce the space volume occupied by the first groove 1321 and the second groove 1322. When the first edge 123 is in the first position, the over-box volume of the door body 12 is the largest, and the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is still small, that is, the arrangement of the first axis 1311 and the second axis 1312, the first groove 1321 and the second groove 1322 is relatively compact, so that under the premise of ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner, thereby meeting the ultra-thin door requirement of the refrigeration equipment 1.

[0115] In some embodiments, when the first edge 123 is in the first position, the relative angle between the door body 12 and the main body 11 is 25°-80°. For example, when the first edge 123 is in the first position, the relative angle between the door body 12 and the main body 11 can be 65.9°.

[0116] See also Figure 8 According to some embodiments of the present application, when the first edge 123 is located at the first position, the distance between the first edge 123 and the side surface 111 of the main body 11 may be less than or equal to 3 mm.

[0117] It is understood that the side surface 111 of the main body 11 is the surface of the main body 11 on the side closest to the surrounding environment. When the door body 12 is in the closed state, the side wall 122 can be flush with the side surface 111 of the main body 11, that is, the first edge 123 is aligned with the side surface 111 of the main body 11. When the door body 12 is opened from the closed state, the first edge 123 will move relative to the main body 11, and when the door body 12 is opened to a certain angle, it will extend outward beyond the side surface 111 of the main body 11, thereby posing a risk of interference with the surrounding environment. At this time, the distance between the first edge 123 and the side surface 111 of the main body 11 is the over-box amount.

[0118] When the first edge 123 is in the first position, the distance between the first edge 123 and the surrounding environment parts is the smallest, that is, when the first edge 123 is in the farthest position extending out from the side 111 of the main body 11, in order to avoid the first edge 123 from contacting the surrounding environment parts, it is limited that when the first edge 123 is in the first position, the distance between the first edge 123 and the side 111 of the main body 11 is less than or equal to 3 mm, that is, the maximum over-box amount of the first edge 123 is less than or equal to 3 mm, so that the maximum distance between the refrigeration equipment 1 and the surrounding environment parts is only 3 mm, and the door body 12 can be opened smoothly, meeting the embedded installation requirements.

[0119] Among them, when the first edge 123 is in the first position, the distance L1 between the first edge 123 and the side surface 111 of the main body 11 has a value range of [0mm, 3mm]. For example, L1 can be 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm or other values ​​of 3mm, which are not specifically limited here.

[0120] In some embodiments, when the first edge 123 is in the first position, the first edge 123 can be located within the side surface 111 of the main body 11, so that the door body 12 does not extend beyond the side surface 111 of the main body 11. In this case, the excess of the door body 12, that is, the distance from the first edge 123 to the side surface 111 of the main body 11, is considered to be a negative value. In this case, the distance L1 between the first edge 123 and the side surface 111 of the main body 11 can be in the range of [-3mm, 0mm]. For example, L1 can be -3mm, -2.5mm, -2mm, -1.5mm, -1mm, -0.5mm, or other values ​​between -3mm and 0mm.

[0121] See also Figure 8 According to some embodiments of the present application, when the first edge 123 is located at the first position, the first edge 123 is adapted to have a distance L2 from the surrounding environment that is greater than or equal to 1 mm.

[0122] By limiting the distance between the first edge 123 and the surrounding environment, it is not easy to interfere with the surrounding environment when the first edge 123 extends the farthest from the side 111 of the main body 11. The distance L2 between the first edge 123 and the surrounding environment can be 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm or other values ​​greater than 1mm.

[0123] See also Figure 10 According to some embodiments of the present application, when the first edge 123 is at the first position, the angle α1 between the line connecting the axes of the first axis 1311 and the second axis 1312 and the front wall 121 is -51° to -21°.

[0124] During the process of opening the door body 12 from a closed state, the angle between the axis line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 first decreases and then increases. Before the door body 12 is opened to the point where the first edge 123 is located in the first position, the axis line connecting the centers of the first axis 1311 and the second axis 1312 is parallel to the front wall 121.

[0125] It should be noted here that, for the sake of distinction, when the first axis 1311 is located on the side of the second axis 1312 away from the front wall 121, the angle between the axis line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 is a positive value; when the first axis 1311 is located on the side of the second axis 1312 close to the front wall 121, the angle between the axis line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 is a negative value.

[0126] When the first edge 123 is in the first position, the angle α1 between the line connecting the axes of the first axis 1311 and the second axis 1312 and the front wall 121 is in the range of [-51°, -21°]. For example, α1 can be -51°, -45°, -40°, -36.3°, -30°, -25°, -21° or other angles between -51° and -21°, which are not specifically limited here.

[0127] See also Figure 8 and Figure 9 According to some embodiments of the present application, when the door body 12 is in the closed state, the distance between the axis center of the first axis 1311 and the side wall 122 is B0, and when the first edge 123 is in the first position, the distance between the axis center of the first axis 1311 and the first edge 123 is E1, which can meet the following requirements:

[0128] E1-B0≤3.1mm.

[0129] It can be understood that when the door body 12 is in the closed state, the side wall 122 is flush with the side 111 of the main body 11, and at this time the side wall 122 is the part of the door body 12 closest to the surrounding environment parts. When the door body 12 is rotated to the first edge 123 being in the first position, the risk of interference between the first edge 123 and the surrounding environment parts is the highest. By limiting E1-B0≤3.1mm to control the size of the first edge 123 exceeding the side 111 of the main body 11, it is ensured that the refrigeration equipment 1 can be better embedded for use.

[0130] Among them, E1-B0 can be 1.1mm, 1.6mm, 2.1mm, 2.6mm, 3.1mm or other values ​​less than 3.1mm.

[0131] In another example, when the first edge 123 is in the first position, the first edge 123 may not exceed the side 111 of the main body 11, that is, the amount of excess of the door body 12 during the rotation process is 0. At this time, the distance E1 from the axis of the first shaft 1311 to the first edge 123 is less than B0, and E1-B0 can be 0 or a negative value.

[0132] See also Figure 9According to some embodiments of the present application, when the first edge 123 is located in the first position, the distance W1 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12 is 5mm-15mm, and the distance M1 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12 is 5mm-15mm.

[0133] By limiting the interval W1 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12, and the interval M1 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12, the spacing between the first axis 1311 and the second axis 1312 is constrained, so that the layout of the first axis 1311 and the second axis 1312 is compacted and the occupied space is reduced.

[0134] Among them, the value range of the interval W1 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12 is [5mm, 15mm]. For example, W1 can be 5mm, 7mm, 7.8mm, 9mm, 10mm, 12mm, 15mm or other values ​​between 5mm-15mm, which are not specifically limited here.

[0135] The range of the distance M1 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12 is [5mm, 15mm]. For example, M1 can be 5mm, 7mm, 9mm, 10mm, 12mm, 13.7mm, 15mm or other values ​​between 5mm-15mm, which are not specifically limited here.

[0136] See also Figure 10 According to some embodiments of the present application, when the first edge 123 moves to the first position, the angle β1 between the tangent of the first axis 1311 relative to the moving direction of the first groove 1321 and the front wall 121 is -25° to -45°, the angle γ1 between the tangent of the second axis 1312 relative to the moving direction of the second groove 1322 and the front wall 121 is 50° to 70°, and the angle θ1 between the tangent of the first axis 1311 relative to the moving direction of the first groove 1321 and the tangent of the second axis 1312 relative to the moving direction of the second groove 1322 is 75° to 115°.

[0137] It should be noted that, for the sake of distinction, when the movement direction of the first shaft 1311 and the second shaft 1312 is away from the front wall 121, the angle between the tangent line of the shaft relative to the movement direction of the slot and the front wall 121 is positive.

[0138] By limiting the movement of the first edge 123 to the first position, the angle between the tangent of the first axis 1311 and the second axis 1312 relative to the movement direction of the door body 12 and the front wall 121, as well as the angle between the tangent of the first axis 1311 and the second axis 1312 relative to the movement direction of the door body 12, the movement direction of the first edge 123 is constrained to move away from the surrounding environment parts when the door body 12 continues to rotate, thereby avoiding interference between the first edge 123 and the surrounding environment parts due to being too close.

[0139] Among them, the value range of β1 is [-25°, -45°]. For example, β1 can be -25°, -30°, -35°, -38.8°, -40°, -45° or other angles between -25° and -45°, and is not specifically limited here.

[0140] The value range of γ1 is [50°, 70°]. For example, γ1 can be 50°, 55°, 60°, 63.2°, 65°, 70°, or other angles between 50° and 70°, which is not specifically limited here.

[0141] The value range of θ1 is [75°, 115°]. For example, θ1 can be 75°, 80°, 90°, 102°, 110°, 115°, or other angles between 75° and 115°, and is not specifically limited here.

[0142] See also Figure 11 and Figure 12 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is 90°, the distance A2 between the axis center of the first axis 1311 and the front wall 121 is 12mm-22mm, the distance B2 between the axis center of the first axis 1311 and the side wall 122 is 9mm-19mm, the distance C2 between the axis center of the second axis 1312 and the front wall 121 is 28mm-38mm, and the distance D2 between the axis center of the second axis 1312 and the side wall 122 is 17mm-27mm.

[0143] The relative angle of 90° between the door body 12 and the main body 11 is the most commonly used opening angle of the door body 12. By limiting the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 at this position, the door body 12 is controlled to open to 90°. When the distance between the embedded refrigeration equipment 1 and the surrounding environment is very small, the relative position of the door body 12 is controlled so as not to exceed the box amount too much or intrude too much, which is convenient for users to use when the door body 12 is normally opened.

[0144] Moreover, when the relative angle between the door body 12 and the main body 11 is 90°, the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is relatively small. While the hinge assembly 13 itself has a compact structure, the distance between the hinge assembly 13 and the front wall 121 and the side wall 122 is also relatively small. The matching size of the hinge assembly 13 and the door body 12 is more compact, which facilitates reducing the thickness of the door body 12.

[0145] Among them, the distance A2 between the axis center of the first axis 1311 and the front wall 121 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the front wall 121. The value range of A2 is [12mm, 22mm]. For example, A2 can be 12mm, 14mm, 16mm, 18mm, 19.5mm, 20mm, 22mm or other values ​​between 12mm-22mm, which are not specifically limited here.

[0146] The distance B2 between the axis center of the first axis 1311 and the side wall 122 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the side wall 122. The value range of B2 is [9mm, 19mm]. For example, B2 can be 9mm, 11mm, 11.2mm, 13mm, 15mm, 17mm, 19mm or other values ​​between 9mm-19mm, which are not specifically limited here.

[0147] The distance C2 between the axis center of the second axis 1312 and the front wall 121 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the front wall 121. The value range of C2 is [28mm, 38mm]. For example, C2 can be 28mm, 30mm, 32mm, 34mm, 34.5mm, 36mm, 38mm or other values ​​between 28mm-38mm, which is not specifically limited here.

[0148] The distance D2 between the axis center of the second axis 1312 and the side wall 122 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the side wall 122. The value range of D2 is [17mm, 27mm]. For example, D2 can be 17mm, 20mm, 21mm, 22mm, 23mm, 25mm, 27mm or other values ​​between 17mm-27mm, which are not specifically limited here.

[0149] According to the refrigeration equipment 1 of the embodiment of the present application, the first groove 1321 and the second groove 1322 are arranged to be connected to each other, so as to shorten the distance between the first groove 1321 and the second groove 1322 and reduce the space volume occupied by the first groove 1321 and the second groove 1322. When the relative angle between the door body 12 and the main body 11 is 90°, the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is still small, that is, the arrangement of the first axis 1311 and the second axis 1312, the first groove 1321 and the second groove 1322 is relatively compact, so that under the premise of ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner, thereby meeting the ultra-thin door requirement of the refrigeration equipment 1.

[0150] See also Figure 11 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is 90°, the intrusion amount H1 of the door body 12 is less than or equal to 63 mm.

[0151] The intrusion amount of the door body 12 is the intrusion amount relative to the side 111 of the main body 11 toward the center of the main body 11 after the door body 12 is opened. When the user takes and places items from the refrigeration device 1, the smaller the intrusion amount, the more convenient it is to use. For example, when a drawer is provided in the refrigeration device 1, there is a scenario where the drawer is pulled out. The smaller the intrusion amount of the door body 12, the smaller the chance of interference between the drawer and the door body 12. At the same time, the drawer can also be made wider to increase the storage space.

[0152] Among them, the door body 12 may include a rear wall 124 opposite to the front wall 121, and a door seal 14 is provided on the rear wall 124. When the door body 12 is in a closed state, the door seal 14 is clamped between the rear wall 124 and the main body 11, playing the role of sealing and heat insulation. When the relative angle between the door body 12 and the main body 11 is 90°, the vertical distance between the end face of the door seal 14 away from the door body 12 and the side face 111 of the main body 11 is the largest, that is, the intrusion amount of the door body 12 at this time is the vertical distance between the end face of the door seal 14 away from the door body 12 and the side face 111 of the main body 11.

[0153] In the related art, in order to allow the door body to avoid the surrounding environment, the door body generally moves laterally a long distance, resulting in a large intrusion amount, which has a great impact on the internal design of the refrigeration equipment. For example, the drawer width needs to be reduced to facilitate the pulling and pulling of the drawer. This application limits the intrusion amount of the door body 12 to less than or equal to 63mm, thereby controlling the intrusion amount of the door body 12 within a smaller range, thereby improving the user experience.

[0154] For example, the intrusion amount H1 of the door body 12 may be 63 mm, 60 mm, 59 mm, 57 mm, 56.5 mm, 56.4 mm, or other values ​​less than 63 mm.

[0155] In one example, the intrusion amount of the door body 12 is 56.5 mm, and the vertical distance between the front wall 121 of the door body 12 and the side surface 111 of the main body 11 is only 1 mm. The intrusion amount is small and the user experience is better.

[0156] See also Figure 11 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is 90°, the distance F between the front wall 121 and the side surface 111 of the main body 11 is less than or equal to 3 mm.

[0157] When the relative angle between the door body 12 and the main body 11 is 90°, the front wall 121 is parallel to the side 111 of the main body 11. Because the surrounding environment needs to be avoided during the opening process of the door body 12, the door body 12 as a whole will move toward the center of the main body 11, so that when the door body 12 is at 90°, the front wall 121 of the door body 12 is located on the side 111 of the main body 11 close to the center of the main body 11. The distance F between the front wall 121 and the side 111 of the main body 11 is the inward displacement of the door body 12. By limiting the inward displacement to reduce the encroachment of the door body 12 on the usable space, the drawer can be made larger and more beautiful.

[0158] Among them, the value of F can be 3mm, 2.5mm, 2mm, 1.5mm, 1mm, 0.5mm or other values ​​less than 3mm, and is not specifically limited here.

[0159] See also Figure 6 and Figure 12 According to some embodiments of the present application, when the door body 12 is in a closed state, the distance A0 between the axis of the first axis 1311 and the front wall 121, and when the relative angle between the door body 12 and the main body 11 is 90°, the distance B2 between the first axis 1311 and the side wall 122 can meet the following requirements:

[0160] -3mm≤B2-A0≤3mm.

[0161] It can be understood that when the door body 12 is in the closed state, the side wall 122 of the door body 12 is aligned with the side 111 of the main body 11. Therefore, the distance between the axis of the first axis 1311 and the side wall 122 is the distance between the axis of the first axis 1311 and the side 111 of the main body 11; when the relative angle between the door body 12 and the main body 11 is 90°, the side wall 122 is rotated to be perpendicular to the side 111 of the main body 11, and the front wall 121 is parallel to the main body 11. Because the first axis 1311 is relatively fixed to the main body 11, the distance between the axis of the first axis 1311 and the front wall 121 can be used to calculate the vertical distance between the front wall 121 and the side 111 of the main body 11 when the door body 12 is opened to 90°, and then the intrusion amount of the door body 12 in the 90° state can be judged.

[0162] By limiting -3mm≤B2-A0≤3mm, the intrusion amount of the door body 12 can be controlled within an extremely small range, thereby improving the user experience of the refrigeration device 1.

[0163] Among them, B2-A0 can take the value of -3mm, -2mm, -1mm, 0mm, 1mm, 2mm, 3mm or other values ​​between -3mm and 3mm, which are not specifically limited here.

[0164] See also Figure 13 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is 90°, the angle between the axis of the first axis 1311 and the axis of the second axis 1312 and the front wall 121 of the door body 12 is -75° to -45°.

[0165] During the process of opening the door body 12 from a closed state, the angle between the axis line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 first decreases and then increases. Before the door body 12 opens to a relative angle of 90° with the main body 11, the axis line connecting the centers of the first axis 1311 and the second axis 1312 is parallel to the front wall 121.

[0166] When the relative angle between the door body 12 and the main body 11 is 90°, the angle α2 between the line connecting the axes of the first axis 1311 and the second axis 1312 and the front wall 121 is in the range of [-75°, -45°]. For example, α2 can be -75°, -70°, -65°, -60.4°, -55°, -50°, -45° or other angles between -75° and -45°, which are not specifically limited here.

[0167] See also Figure 12 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is 90°, the distance W2 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12 is 5mm-15mm, and the distance M2 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12 is 5mm-15mm.

[0168] By limiting the interval W2 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12, and the interval M2 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12, the spacing between the first axis 1311 and the second axis 1312 is constrained, so that the layout of the first axis 1311 and the second axis 1312 is compacted and the occupied space is reduced.

[0169] Among them, the value range of the interval W1 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12 is [5mm, 15mm]. For example, W2 can be 5mm, 7mm, 9mm, 11mm, 13mm, 13.7mm, 15mm or a value between 5mm-15mm, which is not specifically limited here.

[0170] The value range of the interval M1 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12 is [5mm, 15mm]. For example, M2 can be 5mm, 7mm, 7.8mm, 9mm, 11mm, 13mm, 15mm or a value between 5mm-15mm, which is not specifically limited here.

[0171] See also Figure 13 According to some embodiments of the present application, when the door body 12 is opened to 90°, the angle β2 between the tangent of the first axis 1311 relative to the moving direction of the first slot 1321 and the front wall 121 is -25° to -45°, the angle γ2 between the tangent of the second axis 1312 relative to the moving direction of the second slot 1322 and the front wall 121 is 5° to 25°, and the angle θ2 between the tangent of the first axis 1311 relative to the moving direction of the first slot 1321 and the tangent of the second axis 1312 relative to the moving direction of the second slot 1322 is 30° to 70°.

[0172] By limiting the angles β2 and γ2 between the tangents of the first axis 1311 and the second axis 1312 relative to the moving direction of the door body 12 and the front wall 121, as well as the angle θ2 between the tangents of the first axis 1311 and the second axis 1312 relative to the moving direction of the door body 12 when the door body 12 is opened to 90°, the posture of the door body 12 when it continues to rotate is constrained, thereby avoiding direct interference between the door body 12 and the surrounding environment, and allowing the door body 12 to continue to open to a larger angle.

[0173] Among them, the value range of β2 is [-25°, -45°]. For example, β2 can be -25°, -30°, -34.9°, -40°, -45° or other angles between -25° and -45°, and is not specifically limited here.

[0174] The value range of γ2 is [5°, 25°]. For example, γ2 can be 5°, 10°, 15°, 17.1°, 20°, 25° or other angles between 5° and 25°, and is not specifically limited here.

[0175] The value range of θ2 is [30° to 70°]. For example, θ2 can be 30°, 35°, 40°, 45°, 50°, 52°, 60°, 70° or other angles between 30° and 70°, and is not specifically limited here.

[0176] See also Figure 14 and Figure 15 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is the largest, the distance A3 between the axis center of the first axis 1311 and the front wall 121 is 7mm-17mm, the distance B3 between the axis center of the first axis 1311 and the side wall 122 is 4.5mm-14.5mm, the distance C3 between the axis center of the second axis 1312 and the front wall 121 is 21mm-31mm, and the distance D3 between the axis center of the second axis 1312 and the side wall 122 is 4mm-14mm.

[0177] It can be understood that the maximum relative angle between the door body 12 and the main body 11 is when the door body 12 is opened to the maximum angle, and the maximum relative angle between the door body 12 and the main body 11 exceeds 90°. After the door body 12 is opened to 90°, because there is a certain gap between the door body 12 and the surrounding environment parts, the door body 12 can continue to open to the maximum angle for user use. By limiting the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 at this position, the posture of the door body 12 relative to the main body 11 when the door body 12 is opened to the maximum angle is controlled. When the distance between the embedded refrigeration equipment 1 and the surrounding environment parts is very small, the maximum angle is ensured to be sufficient for user use.

[0178] Moreover, when the relative angle between the door body 12 and the main body 11 is the largest, the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is relatively small. While the hinge assembly 13 itself has a compact structure, the distance between the hinge assembly 13 and the front wall 121 and the side wall 122 is also relatively small. The matching size of the hinge assembly 13 and the door body 12 is more compact, which facilitates reducing the thickness of the door body 12.

[0179] Among them, the distance A3 between the axis center of the first axis 1311 and the front wall 121 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the front wall 121. The value range of A3 is [7mm, 17mm]. For example, A3 can be 7mm, 9mm, 11mm, 11.6mm, 13mm, 15mm, 17mm or other values ​​between 7mm-17mm, which are not specifically limited here.

[0180] The distance B3 between the axis center of the first axis 1311 and the side wall 122 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the side wall 122. The value range of B3 is [4.5mm, 14.5mm]. For example, B3 can be 4.5mm, 6mm, 8mm, 9.7mm, 12mm, 14mm, 14.5mm or other values ​​between 4.5mm-14.5mm, which is not specifically limited here.

[0181] The distance C3 between the axis center of the second axis 1312 and the front wall 121 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the front wall 121. The value range of C3 is [21mm, 31mm]. For example, C3 can be 21mm, 23mm, 25mm, 27mm, 27.4mm, 29mm, 31mm or other values ​​between 21mm-31mm, which is not specifically limited here.

[0182] The distance D3 between the axis center of the second axis 1312 and the side wall 122 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the side wall 122. The value range of D3 is [4mm, 14mm]. For example, D3 can be 4mm, 6mm, 8mm, 9.6mm, 10mm, 12mm, 14mm or other values ​​between 4mm-14mm, which are not specifically limited here.

[0183] According to the refrigeration equipment 1 of the embodiment of the present application, the first groove 1321 and the second groove 1322 are arranged to be connected to each other, so as to shorten the distance between the first groove 1321 and the second groove 1322 and reduce the space volume occupied by the first groove 1321 and the second groove 1322. When the relative angle between the door body 12 and the main body 11 is the largest, the opening angle of the door body 12 is the largest, and the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is still small, that is, the arrangement of the first axis 1311 and the second axis 1312, the first groove 1321 and the second groove 1322 is relatively compact, so that under the premise of ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner, thereby meeting the ultra-thin door requirement of the refrigeration equipment 1.

[0184] See also Figure 11 and Figure 14 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is the largest, the intrusion amount H1 of the door body 12, and when the relative angle between the door body 12 and the main body 11 is 90°, the intrusion amount H2 of the door body 12, can meet the following requirements:

[0185] H1 <H2。

[0186] It can be understood that the door body 12 also includes a rear wall 124 opposite to the front wall 121, and the rear wall 124 intersects with the side wall 122 at a second edge 125. After the relative angle between the door body 12 and the main body 11 is greater than 90°, the second edge 125 will continue to move toward the center of the opening close to the main body 11, and when the relative angle between the door body 12 and the main body 11 is the largest, the second edge 125 is the part of the entire door body 12 closest to the center of the opening of the main body 11, that is, at this time, the distance between the second edge 125 and the side 111 of the main body 11 is the intrusion amount of the door body 12.

[0187] It is understandable that when general users use the refrigeration equipment 1, the most common usage state is to open the door body 12 to 90°. Therefore, the internal design of the refrigeration equipment 1 will ensure that the door body 12 can normally take out and put items when it is opened to 90°. For example, when a drawer is provided in the refrigeration equipment 1, the door body 12 will not affect the pulling and pulling of the drawer. The purpose of further opening after opening to 90° is to provide a better user experience. By limiting the intrusion amount L1<L2, when the relative angle between the door body 12 and the main body 11 is the largest, it will not affect the normal use of the refrigeration equipment 1, for example, it will not affect the normal pulling and pulling of the drawer.

[0188] See also Figure 14 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is the largest, the intrusion amount H2 of the door body 12 is less than or equal to 63 mm.

[0189] In the related art, in order to allow the door body to avoid the surrounding environment, the intrusion amount is generally large, which has a great impact on the internal design of the refrigeration equipment. For example, the drawer width needs to be reduced to facilitate the pulling and pulling of the drawer. This application limits the intrusion amount of the door body 12 when the relative angle between the door body 12 and the main body 11 is the largest, so as to control the intrusion amount of the door body 12 within an extremely small range, which has little impact on the use of the refrigeration equipment 1 and improves the user experience.

[0190] For example, the intrusion amount H2 of the door body 12 can be 63 mm, 60 mm, 59 mm, 57 mm, 56.5 mm, 56.4 mm or other values ​​less than 63 mm, which are not specifically limited here.

[0191] See also Figure 16 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is the largest, the angle α3 between the line connecting the axes of the first axis 1311 and the second axis 1312 and the front wall 121 is -105° to -75°.

[0192] In the process of the door body 12 opening from 90° to the maximum angle, the angle between the axis connection line of the first axis 1311 and the second axis 1312 and the front wall 121 gradually increases. When the door body 12 is opened to the maximum angle, the angle α3 between the axis connection line of the first axis 1311 and the second axis 1312 and the front wall 121 is in the range of [-105°, -75°]. For example, α3 can take the value of -105°, -100°, -95°, -90.4°, -85°, -80°, -75° or other angles between -105° and -75°, which are not specifically limited here.

[0193] See also Figure 15 According to some embodiments of the present application, when the relative angle between the door body 12 and the main body 11 is the largest, the distance between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12 is 10mm-25mm, and the distance between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12 is 0-5mm.

[0194] By limiting the distance between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12, as well as the distance between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12, the spacing between the first axis 1311 and the second axis 1312 is constrained, so that the layout of the first axis 1311 and the second axis 1312 is compacted and the occupied space is reduced.

[0195] Among them, the value range of the interval W3 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the thickness direction of the door body 12 is [10mm, 25mm]. For example, W3 can be 10mm, 12mm, 14mm, 15.8mm, 18mm, 20mm, 22mm, 25mm or other values ​​between 10mm-25mm, which are not specifically limited here.

[0196] The value range of the interval M3 between the axis center of the first axis 1311 and the axis center of the second axis 1312 in the width direction of the door body 12 is [0, 5mm]. For example, M3 can be 0mm, 0.1mm, 0.2mm, 1mm, 2mm, 3mm, 4mm, 5mm or other values ​​between 0-5mm, which are not specifically limited here.

[0197] See also Figure 16According to some embodiments of the present application, when the door body 12 is opened to the maximum relative angle with the main body 11, the angle β3 between the tangent of the first axis 1311 relative to the moving direction of the first slot 1321 and the front wall 121 is -120° to -140°, the angle γ3 between the tangent of the second axis 1312 relative to the moving direction of the second slot 1322 and the front wall 121 is -55° to -75°, and the angle θ3 between the tangent of the first axis 1311 relative to the moving direction of the first slot 1321 and the tangent of the second axis 1312 relative to the moving direction of the second slot 1322 is 50° to 70°.

[0198] By limiting the angles β3 and γ3 between the tangents of the first axis 1311 and the second axis 1312 relative to the moving direction of the door body 12 and the front wall 121, as well as the angle θ3 between the tangents of the moving direction of the first axis 1311 and the second axis 1312 when the door body 12 is opened to the maximum angle, the stability of the door body 12 when it rotates to the maximum angle is constrained, and the intrusion amount of the door body 12 is controlled.

[0199] Among them, the value range of β3 is [-120°, -140°]. For example, β3 can be -120°, -125°, -129°, -133°, -135°, -140° or other angles between -120° and -140°, and is not specifically limited here.

[0200] The value range of γ3 is [-55°, -75°]. For example, γ3 can be -55°, -60°, -65°, -67°, -70°, -75° or other angles between -55° and -75°, which is not specifically limited here.

[0201] The value range of θ3 is [50° to 70°]. For example, θ3 can be 50°, 55°, 58°, 60°, 65°, 70° or other angles between 50° and 70°, and is not specifically limited here.

[0202] According to some embodiments of the present application, the maximum relative angle between the door body 12 and the main body 11 can be 115°-125°.

[0203] Exemplarily, the maximum relative angle between the door body 12 and the main body 11 can be 115°, 117°, 120°, 121°, 123°, 125° or other angles between 115° and 125°, which are not specifically limited here.

[0204] See also Figure 17 、 Figure 18 、 Figure 19 and Figure 20According to some embodiments of the present application, in the process of the door body 12 opening from a closed state to a maximum angle, the first shaft 1311 can slide relative to the first slot 1321, so that the first shaft 1311 first moves away from and then approaches the front wall 121 to form a first trajectory a, the first shaft 1311 moves back and forth away from and close to the front wall 121 to form a second trajectory b, and the first shaft 1311 moves close to the front wall 121 to form a third trajectory c; the second shaft 1312 can slide relative to the second slot 1322, so that the second shaft 1312 moves away from the front wall 121 to form a fourth trajectory d, and the second shaft 1312 moves close to the front wall 121 to form a fifth trajectory e.

[0205] Because the first shaft 1311 and the second shaft 1312 are fixed to the main body 11, when the door body 12 rotates, the first shaft 1311 and the second shaft 1312 move relative to the door body 12 and the first groove 1321 and the second groove 1322 on the door body 12. When the door body 12 is opened from the closed state to the maximum angle, the total motion trajectory of the first shaft 1311 can be divided into a first trajectory a, a second trajectory b, and a third trajectory c in sequence.

[0206] Among them, the first trajectory a includes two sections, which first extend away from the front wall 121 and then extend closer to the front wall 121; the second trajectory b includes two ends, which first extend away from the front wall 121 and then extend closer to the front wall 121, and, because the first shaft 1311 reciprocates to form the second trajectory b, the two ends of the second trajectory b overlap with each other, and in the second trajectory b, the section extending away from the front wall 121 overlaps with the first trajectory a on the trajectory path, so that when the first shaft 1311 moves along the second trajectory b, a retreat is formed in the overall direction of movement; the third trajectory c extends close to the front wall 121.

[0207] It can be understood that the fourth track d and the fifth track e are misaligned with the first track a, the second track b and the third track c to avoid interference between the first axis 1311 and the second axis 1312, wherein the fourth track d extends in a direction away from the front wall 121 and the fifth track e extends in a direction close to the front wall 121.

[0208] By limiting the movement trajectory of the first axis 1311 and the second axis 1312, in the initial stage of the door body 12 opening from the closed state to the maximum angle, the first axis 1311 and the second axis 1312 both move in the direction away from the front wall 121, so that the door body 12 has a tendency to move in the direction away from the main body 11 to avoid interference between the door body 12 and the main body 11; in the middle stage of the door body 12 opening from the closed state to the maximum angle, the first axis 1311 forms a retraction in the movement direction, and the retraction is set to effectively control the over-box amount of the door body 12 during the rotation process, and cooperates with the movement of the second axis 1312 to make the door body 12 rotate and open quickly, reducing the space occupied by the running trajectory of the first axis 1311 during the rotation of the door body 12, thereby facilitating the reduction of the space occupied by the entire hinge assembly 13; in the final stage of the door body 12 opening from the closed state to the maximum angle, the first axis 1311 and the second axis 1312 both move in the direction close to the front wall 121, so as to facilitate the large-angle opening of the door body 12.

[0209] Moreover, it can be seen from the above content that the total motion trajectories of the first axis 1311 and the second axis 1312 both have a turning point, which further reduces the space occupied by the first axis 1311 and the second axis 1312 in the thickness direction of the door body 12 during the relative movement with the door body 12, so that the thickness of the door body 12 can be thinner. Not only can the mass of the door body 12 be lighter, but the thickness distribution of the entire refrigeration equipment 1 is also optimized, thereby improving the sense of luxury and practicality of the refrigeration equipment 1.

[0210] According to the refrigeration device 1 of the embodiment of the present application, by limiting the movement trajectory of the first axis 1311 and the second axis 1312, not only can the space occupied by the hinge assembly 13 during rotation be reduced, which is convenient for the adaptation of the ultra-thin door, but it is also not easy to interfere with the surrounding environment parts, and the door body 12 of the embedded refrigeration device 1 can be opened at a large angle, which is convenient for users to use.

[0211] See also Figures 17-20 According to some embodiments of the present application, when the first axis 1311 moves along the first trajectory a and the second trajectory b, the second axis 1312 moves along the fourth trajectory d; when the second axis 1312 moves along the fifth trajectory e, the first axis 1311 moves along the third trajectory c.

[0212] When the first shaft 1311 moves along the first trajectory a and the second trajectory b, the second shaft 1312 moves along the fourth trajectory d. When the first shaft 1311 moves along the third trajectory c, the second shaft 1312 moves along the fifth trajectory e. Specifically, when the first shaft 1311 moves along the first trajectory a, the distance between the first shaft 1311 and the front wall 121 undergoes a turning point. When the first shaft 1311 moves along the second trajectory b, there is a period of retreat and another turning point. While the direction of movement of the first shaft 1311 has undergone two turning points relative to the front wall 121, the second shaft 1312 always moves away from the front wall 121 along the fourth trajectory d. Through the cooperation of the first shaft 1311 and the second shaft 1312, the door body 12 can be quickly opened to the usable opening within a limited movement space.

[0213] When the second axis 1312 moves along the fifth trajectory e toward the front wall 121, the first axis 1311 moves along the third trajectory c toward the front wall 121 to increase the distance between the front wall 121 and the surrounding environmental parts. In the embedded refrigeration equipment 1, it is convenient for the front wall 121 of the door body 12 to avoid the surrounding environmental parts and achieve a large-angle opening.

[0214] See also Figure 17 According to some embodiments of the present application, when the door body 12 is opened from a closed state to a first angle, the first axis 1311 moves along a first trajectory a, and the second axis 1312 moves along a fourth trajectory d.

[0215] The first axis 1311 first moves away from the front wall 121 along the first trajectory a, and then moves closer to the front wall 121. The second axis 1312 moves away from the front wall 121 along the fourth trajectory d. It can be seen that the first axis 1311 first passes through an inflection point of direction during the movement. The first axis 1311 and the second axis 1312 first move away from the front wall 121 together, which can make the door body 12 as a whole move away from the main body 11 first, so that the door body 12 is not easily interfered with the main body 11 during the subsequent opening process. Then the first axis 1311 moves in a direction close to the front wall 121, so that the instantaneous rotation center of the door body 12 quickly approaches the door body 12. After the distance between the door body 12 and the main body 11 is sufficient, the rotation speed of the door body 12 is accelerated, and the intrusion amount of the door body 12 can be reduced.

[0216] Figure 18 and Figure 19 When the door body 12 opens from the first angle to the second angle, the first shaft 1311 first retreats along the second trajectory b and then reciprocates forward, and the second shaft 1312 moves along the fourth trajectory d.

[0217] It is understood that the second angle is greater than the first angle. When the door body 12 continues to open from the first angle, the first shaft 1311 first withdraws along the second trajectory b and then reciprocates forward, causing the first shaft 1311 to first move away from the front wall 121 and then move closer to the front wall 121. During this process, the second shaft 1312 continues to move along the fourth trajectory d away from the front wall 121. The withdrawal of the first shaft 1311 can control the amount of overrun by the first edge 123 during the rotation of the door body 12, and can also enable the door body 12 to open quickly. In addition, the withdrawal motion reduces the space occupied by the motion trajectory of the first shaft 1311. This corresponds to a smaller size required for the first slot 1321 on the door body 12, thereby reducing the space occupied by the entire hinge assembly 13.

[0218] See also Figure 20 In the process of the door body 12 opening from the second angle to the maximum angle, the first axis 1311 moves along the third track c, and the second axis 1312 moves along the fifth track e.

[0219] When the door body 12 continues to open from the second angle, the first axis 1311 moves along the third trajectory c close to the front wall 121, and the second axis 1312 also moves along the fifth trajectory e close to the front wall 121. The corresponding front wall 121 moves as a whole in the direction close to the first axis 1311 and the second axis 1312, which can increase the distance between the front wall 121 and the surrounding environment parts. In the embedded refrigeration equipment 1, it is convenient for the front wall 121 of the door body 12 to avoid the surrounding environment parts and achieve a large angle opening.

[0220] See also Figures 17-20 According to some embodiments of the present application, the first axis 1311 moves close to the side wall 122 along the first trajectory a, moves away from the side wall 122 when retracting along the second trajectory b, and moves close to the side wall 122 again after the retraction is completed. The first axis 1311 first moves close to the side wall 122 along the third trajectory c, and then moves away from the side wall 122; the second axis 1312 always moves close to the side wall 122 along the fourth trajectory d and the fifth trajectory e.

[0221] In the initial stage when the door body 12 is opened from the closed state to the maximum angle, the first axis 1311 moves along the first track a close to the side wall 122, and the second axis 1312 moves along the fourth track d close to the side wall 122, so that the door body 12 has a tendency to move toward the side close to the center of the opening relative to the main body 11, thereby avoiding interference with the surrounding environment parts close to the side wall 122 when the door body 12 is opened; in the middle stage when the door body 12 is opened from the closed state to the maximum angle, the first axis 1311 retracts along the second track b, so that the first axis 1311 moves away from the side wall 122, and the second axis 1312 moves close to the side wall 122 moves to control the amount of the first edge 123 connected to the side wall 122 to not be too large, meet the needs of embedded installation, and enable the door body 12 to rotate quickly; in the later stage when the door body 12 is opened from a closed state to a maximum angle, the first axis 1311 moves along the third trajectory c first close to the side wall 122, and then moves away from the side wall 122, so as to facilitate the large-angle rotation and opening of the door body 12, and control the space occupied by the movement trajectory of the first axis 1311, so that the structure of the entire hinge assembly 13 is more compact, and can also be used with the ultra-thin door body 12 to achieve large-angle opening, and the intrusion into the main body 11 is small.

[0222] According to some embodiments of the present application, in the process of the door body 12 opening from a closed state to a first angle, the virtual rotation center and the side wall 122 of the door body 12 are respectively located on both sides of the axis line connecting the first axis 1311 and the second axis 1312; in the process of the door body 12 opening from the first angle to the third angle, the virtual rotation center and the side wall 122 of the door body 12 are located on the same side of the axis line connecting the first axis 1311 and the second axis 1312; in the process of the door body 12 opening from the third angle to the maximum angle, the virtual rotation center and the side wall 122 of the door body 12 are respectively located on both sides of the axis line connecting the first axis 1311 and the second axis 1312; wherein, the third angle is the angle of the door body 12 when the first axis 1311 retracts to the limit.

[0223] It can be understood that the third angle is greater than the first angle and smaller than the second angle.

[0224] According to some embodiments of the present application, when the relative angles between the door body 12 and the main body 11 are the first angle and the third angle, the virtual rotation center of the door body 12 is located at the axis center of the first axis 1311 .

[0225] In the process of the door body 12 opening from the closed state to the first angle, the virtual rotation center of the door body 12 is located on the side of the line connecting the axis centers of the first axis 1311 and the second axis 1312 away from the side wall 122, and as the door body 12 rotates, it gradually approaches the axis center of the first axis 1311 until the door body 12 is opened to the first angle, and the virtual rotation center of the door body 12 is coaxial with the first axis 1311; in the process of the door body 12 opening from the first angle to the third angle, the virtual rotation center of the door body 12 is located on the side of the line connecting the axis centers of the first axis 1311 and the second axis 1312 away from the side wall 122. The line connecting the side axes of the first axis 1311 and the second axis 1312 is close to the side wall 122 and first moves away and then approaches, until the door body 12 rotates to the third angle, the first axis 1311 retreats to the extreme position, and the virtual rotation center of the door body 12 is coaxial with the first axis 1311; in the process of the door body 12 continuing to rotate from the third angle to the maximum angle, the virtual rotation center of the door body 12 returns to the side of the line connecting the side axes of the first axis 1311 and the second axis 1312 away from the side wall 122.

[0237] See also Figures 17-20 According to some embodiments of the present application, in the process of opening the door body 12 from a closed state to a maximum angle, the first shaft 1311 can slide from a first starting position relative to the first slot 1321, so that the first shaft 1311 first moves away from and then approaches the front wall 121 to form a first trajectory a, the first shaft 1311 moves back and forth away from and close to the front wall 121 to form a second trajectory b, and the first shaft 1311 moves close to the front wall 121 to form a third trajectory c; the second shaft 1312 can slide from a second starting position relative to the second slot 1322, so that the second shaft 1312 moves away from the front wall 121 to form a fourth trajectory d, and the second shaft 1312 moves close to the front wall 121 to form a fifth trajectory e.

[0238] It should be noted that, when the door body 12 is in a closed state, the first axis 1311 is located at a first starting position in the first groove 1321, and the second axis 1312 is located at a second starting position in the second groove 1322.

[0239] In one example, the first starting position is located near the first end of the first slot 1321 , and the second starting position is located near the first end of the second slot 1322 .

[0241] It can be understood that when the first shaft 1311 is located at the first starting position, the second shaft 1312 is located at the second starting position, and the door body 12 is in a closed state.

The value range of D2 is [17mm, 27mm]. For example, D2 can be 17mm, 20mm, 21mm, 22mm, 23mm, 25mm, 27mm or other values ​​between 17mm-27mm, which are not specifically limited here.

[0261] According to the refrigeration device 1 of the embodiment of the present application, by limiting the movement trajectory of the first axis 1311 and the second axis 1312, the space occupied by the hinge assembly 13 during rotation can be reduced, and it is not easy to interfere with the surrounding environment parts, so that the door body 12 of the embedded refrigeration device 1 can be opened at a large angle, which is convenient for users to use. When the door body 12 is opened to 90°, the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is small, that is, the arrangement of the first axis 1311 and the second axis 1312, the first groove 1321 and the second groove 1322 is relatively compact, so that under the premise of ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner, meeting the ultra-thin door requirements of the refrigeration device 1 and facilitating the adaptation of the ultra-thin door.

[0262] See also Figure 17-Figure 19 According to some embodiments of the present application, in the process of the door body 12 being opened from a closed state to a maximum angle, the first shaft 1311 can slide from a first starting position to a first end position relative to the first slot 1321, so that the first shaft 1311 first moves away from and then approaches the front wall 121 to form a first trajectory a, the first shaft 1311 moves back and forth away from and approaching the front wall 121 to form a second trajectory b, and the first shaft 1311 moves close to the front wall 121 to form a third trajectory c; the second shaft 1312 can slide from a second starting position to a second end position relative to the second slot 1322, so that the second shaft 1312 moves away from the front wall 121 to form a fourth trajectory d, and the second shaft 1312 moves close to the front wall 121 to form a fifth trajectory e.

[0263] It should be noted that, when the first shaft 1311 slides to the first end position and the second shaft 1312 slides to the second end position, the door body 12 is in the maximum angle position that can be opened. In the process of the first shaft 1311 sliding from the first starting position to the first end position relative to the first groove 1321, a first track a, a second track b and a third track c are formed. In the process of the second shaft 1312 sliding from the second starting position to the second end position relative to the second groove 1322, a fourth track d and a fifth track e are formed. Among them, the relevant features of the first track a, the second track b, the third track c, the fourth track d and the fifth track e can be referred to the above embodiments and will not be repeated here.

[0264] In one example, the first focus position is located at the second end of the first slot 1321 , and the second focus position is located at the second end of the second slot 1322 .

[0265] See also Figure 15 When the first shaft 1311 is at the first end position, the distance A3 between the axis center of the first shaft 1311 and the front wall 121 is 7mm-17mm, the distance B3 between the axis center of the first shaft 1311 and the side wall 122 is 4.5mm-14.5mm, the distance C3 between the axis center of the second shaft 1312 and the front wall 121 is 21mm-31mm, and the distance D3 between the axis center of the second shaft 1312 and the side wall 122 is 4mm-14mm.

[0266] It can be understood that when the first shaft 1311 is located at the first end position, the second shaft 1312 is located at the second end position, and the door body 12 is opened to the maximum angle.

[0267] At this time, the distance A3 between the axis center of the first axis 1311 and the front wall 121 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the front wall 121. The value range of A3 is [7mm, 17mm]. For example, A3 can be 7mm, 9mm, 11mm, 11.6mm, 13mm, 15mm, 17mm or other values ​​between 7mm-17mm, which are not specifically limited here.

[0268] The distance B3 between the axis center of the first axis 1311 and the side wall 122 refers to the length of a perpendicular line from the axis center of the first axis 1311 to the side wall 122.

[0269] The distance C3 between the axis center of the second axis 1312 and the front wall 121 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the front wall 121. The value range of C3 is [21mm, 31mm]. For example, C3 can be 21mm, 23mm, 25mm, 27mm, 27.4mm, 29mm, 31mm or other values ​​between 21mm-31mm, which is not specifically limited here.

[0270] The distance D3 between the axis center of the second axis 1312 and the side wall 122 refers to the length of a perpendicular line from the axis center of the second axis 1312 to the side wall 122. The value range of D3 is [4mm, 14mm]. For example, D3 can be 4mm, 6mm, 8mm, 9.6mm, 10mm, 12mm, 14mm or other values ​​between 4mm-14mm, which are not specifically limited here.

[0271] According to the refrigeration device 1 of the embodiment of the present application, by limiting the movement trajectory of the first axis 1311 and the second axis 1312, the space occupied by the hinge assembly 13 during rotation can be reduced, and it is not easy to interfere with the surrounding environment parts, so that the door body 12 of the embedded refrigeration device 1 can be opened at a large angle, which is convenient for users to use. When the door body 12 is opened to the maximum angle, the distance between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 is small, that is, the arrangement of the first axis 1311 and the second axis 1312, the first groove 1321 and the second groove 1322 is relatively compact, so that under the premise of ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner, meeting the ultra-thin door requirements of the refrigeration device 1 and facilitating the adaptation of the ultra-thin door.

[0272] See also Figure 16 According to some embodiments of the present application, when the first axis 1311 is at the first end position, the angle α3 between the line connecting the axis centers of the first axis 1311 and the second axis 1312 and the front wall 121 of the door body 12 is -105° to -75°.

[0273] In the process of the door body 12 opening from 90° to the maximum angle, the angle between the axis connection line of the first axis 1311 and the second axis 1312 and the front wall 121 gradually increases. When the first axis 1311 moves to the first end position, the angle α3 between the axis connection line of the first axis 1311 and the second axis 1312 and the front wall 121 is in the range of [-105°, -75°]. For example, α3 can take the value of -105°, -100°, -95°, -90.4°, -85°, -80°, -75° or other angles between -105° and -75°, which are not specifically limited here.

[0274] See also Figure 16According to some embodiments of the present application, when the first axis 1311 is located at the first end position, the angle β3 between the tangent of the first trajectory a at the first axis 1311 and the front wall 121 is -120° to -140°; the angle γ3 between the tangent of the fourth trajectory d at the second axis 1312 and the front wall 121 is -55° to -75°; and the angle θ3 between the tangent of the first trajectory a at the first axis 1311 and the tangent of the fourth trajectory d at the second axis 1312 is 50° to 70°.

[0275] By limiting the angle β3 between the tangent of the first trajectory a at the first axis 1311 and the front wall 121 when the first axis 1311 is at the first end position, and limiting the angle γ3 between the tangent of the fourth trajectory d at the second axis 1312 and the front wall 121 when the second axis 1312 is at the second end position, as well as the angle θ3 between the two tangents, the moving trajectory of the door body 12 when it is opened to the maximum angle is constrained, interference between the door body 12 and the surrounding environment is avoided, the amount of intrusion of the door body 12 at the maximum angle is reduced, and it is convenient for the door body 12 to open at a large angle.

[0276] Among them, the value range of β3 is [-120°, -140°]. For example, β3 can be -120°, -125°, -129°, -133°, -135°, -140° or other angles between -120° and -140°, and is not specifically limited here.

[0277] The value range of γ3 is [-55°, -75°]. For example, γ3 can be -55°, -60°, -65°, -67°, -70°, -75° or other angles between -55° and -75°, which is not specifically limited here.

[0278] The value range of θ3 is [50° to 70°]. For example, θ3 can be 50°, 55°, 58°, 60°, 65°, 70° or other angles between 50° and 70°, and is not specifically limited here.

[0279] See also Figure 5 、 Figure 8 、 Figure 11 and Figure 14According to some embodiments of the present application, the first groove 1321 includes a first inflection point, a first endpoint, and a second endpoint. The first inflection point is located between the first endpoint and the second endpoint and on the side of the first endpoint and the second endpoint away from the front wall 121. The second groove 1322 includes a second inflection point, a third endpoint, and a fourth endpoint. The second inflection point is located between the third endpoint and the fourth endpoint and on the side of the third endpoint and the fourth endpoint away from the front wall 121. Furthermore, the second groove 1322 is located on the side of the first groove 1321 away from the front wall 121, and the first end of the first groove 1321 is connected to the portion between the third end and the second inflection point of the second groove 1322.

[0280] Among them, see Figure 5 When the door body 12 is in the closed state, the first axis 1311 is located at the first end point, and the second axis 1312 is located at the second end point; please refer to Figure 8 When the first edge 123 moves to the first position, the first axis 1311 is located between the first inflection point and the second end point, and the second axis 1312 is located between the third end point and the second inflection point; see Figure 11 When the relative angle between the door body 12 and the main body 11 is 90°, the first axis 1311 is located between the first inflection point and the second end point, and the second axis 1312 is located between the third end point and the second inflection point; see Figure 14 When the door body 12 is opened to the maximum angle, the first axis 1311 is located at the second end point, and the second axis 1312 is located at the fourth end point.

[0281] Among them, part of the first trajectory a is located between the first endpoint and the first inflection point, the other part of the first trajectory a is located between the first inflection point and the second endpoint, the second trajectory b and the third trajectory c are both located between the first inflection point and the second endpoint; the fourth trajectory d is located between the third endpoint and the second inflection point, and the fifth trajectory e is located between the second inflection point and the fourth endpoint.

[0282] See also Figure 11 and Figure 14 According to some embodiments of the present application, during the process of the door body 12 opening from 90° to the maximum angle, the intrusion amount of the door body 12 is less than or equal to 63 mm.

[0283] It can be understood that the normal opening angle required for the use of the drawer is reached only when the relative angle between the door body 12 and the main body 11 reaches 90°. By limiting the intrusion amount of the door body 12 from 90° to the maximum opening angle to be less than or equal to 63mm, the intrusion amount of the door body 12 is controlled within a smaller range. Without interfering with the surrounding environment, the width of the drawer can be made wider to increase the drawer space.

[0284] For example, during the process of the door body 12 opening from 90° to the maximum angle, the maximum intrusion amount of the door body 12 can be 63 mm, 60 mm, 59 mm, 57 mm, 56.5 mm, 56.4 mm or other values ​​less than 63 mm.

[0285] See also Figure 5 、 Figure 8 and Figure 11 According to some embodiments of the present application, during the process of the door body 12 being opened from a closed state to 90°, the over-box amount of the door body 12 is less than or equal to 3 mm.

[0286] It can be understood that when the relative angle between the door body 12 and the main body 11 reaches 90°, which is the most commonly used opening angle of the door body 12, the embedded refrigeration equipment 1 needs to ensure that the door body 12 can be opened at least 90° without interfering with the surrounding environment. By limiting the over-box amount of the door body 12 to be less than or equal to 3mm in the process of opening from the closed state to 90°, the over-box amount of the door body 12 is controlled within an extremely small range, meeting the needs of embedded installation and facilitating the opening of the door body 12.

[0287] For example, during the process of the door body 12 being opened from a closed state to 90 degrees, the maximum over-box amount of the door body 12 can be 0, 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm or other values ​​less than 3 mm.

[0288] In some embodiments, when the door body 12 rotates to a relative angle of 25°-80° with the main body 11 , the first edge 123 of the door body 12 will extend beyond the side surface 111 of the main body 11 .

[0289] See also Figure 11 and Figure 14 According to some embodiments of the present application, during the process of the door body 12 opening from 90° to the maximum angle, the inward displacement of the door body 12 is less than or equal to 3 mm.

[0290] It can be understood that the normal opening angle required for the use of the drawer is reached only when the relative angle between the door body 12 and the main body 11 reaches 90°. By limiting the inward displacement of the door body 12 from 90° to the maximum opening angle to be less than or equal to 3mm, the inward displacement of the door body 12 is controlled within a smaller range. Without interfering with the surrounding environment, the width of the drawer can be made wider, thereby increasing the drawer space.

[0291] Among them, the value of F can be 3mm, 2.5mm, 2mm, 1.5mm, 1mm, 0.5mm or other values ​​less than 3mm, and is not specifically limited here.

[0292] See also Figure 3and Figure 4 According to some embodiments of the present application, the depth of the second groove 1322 is greater than the depth of the first groove 1321 , and the length of the second shaft 1312 is greater than the depth of the first groove 1321 .

[0293] Because the first groove 1321 is connected to the second groove 1322, by setting the depth of the second groove 1322 to be greater than the first groove 1321 and making the length of the second shaft 1312 greater than the first groove 1321, the second shaft 1312 will not enter the first groove 1321, thereby ensuring the stability of the second shaft 1312 moving in the second groove 1322.

[0294] See also Figure 5 According to some embodiments of the present application, the main body 11 is suitable for having a distance R between it and the surrounding environment of 0-6 mm.

[0295] To improve aesthetics, the distance between the embedded refrigeration device 1 and the surrounding environment is generally small. By defining the distance R between the main body 11 and the surrounding environment, the installation and maintenance of the refrigeration device 1 are facilitated while ensuring aesthetics after installation. For example, R can be 0, 1 mm, 2 mm, 3 mm, 4 mm, 4.5 mm, 6 mm, or other values ​​between 0 and 6 mm.

[0296] See also Figure 5 According to some embodiments of the present application, the thickness of the door body 12 can be 42mm-60mm.

[0297] Because the hinge assembly 13 of the present application has a compact structure, the door body 12 can be adapted as an ultra-thin door body 12, thereby reducing the space occupied by the door body 12 on the entire refrigeration equipment 1. The capacity of the entire refrigeration equipment 1 can be increased at the same volume, and the thickness of the entire refrigeration equipment 1 can be reduced at the same capacity.

[0298] Among them, the value range of the thickness S of the door body 12 is [42mm, 60mm]. For example, S can be 42mm, 45mm, 47mm, 50mm, 52mm, 55mm, 58mm, 60mm or other values ​​between 42mm-60mm, which are not specifically limited here.

[0299] According to some embodiments of the present application, the refrigeration device 1 includes at least one of a refrigerator, a freezer, a wine cabinet, a cigar cabinet, and an ice maker.

[0300] Illustratively, the refrigeration device 1 may be a refrigerator.
