Technical Field

[0001] This application belongs to the technical field of refrigeration equipment, and particularly relates to a refrigeration equipment. Background Art

[0002] With the development of society and the gradual improvement of living quality, people's demand for the aesthetic appearance of household refrigeration equipment installation has become increasingly prominent. Embedding the refrigeration equipment into the cabinet, that is, forming an embedded refrigeration equipment to achieve the unified home decoration style has become popular.

[0003] However, in the related art, for the refrigeration equipment installed in an embedded manner, in order to ensure that the door body can be opened smoothly, a double-axis double-slot hinge is generally used. However, the double-axis double-slot hinge has a complex structure and occupies a large space. If the hinge structure is small, it is easy to interfere during opening, and a large-angle door opening cannot be achieved. Utility Model Content

[0004] This application aims to solve at least one of the technical problems existing in the prior art. For this reason, this application proposes a refrigeration equipment, in which the layout of the hinge assembly is compact and occupies a small space. While enabling the door body of the embedded refrigeration equipment to achieve a large-angle door opening, the thickness of the door body can be made thinner.

[0005] This application provides a refrigeration equipment, which includes:

[0006] A main body and a door body, the door body includes side walls and a front wall arranged at an included angle;

[0007] A hinge assembly, including a first hinge member installed on the main body and a second hinge member installed on the door body. A first shaft and a second shaft are fixedly arranged on the first hinge member. The second hinge member includes a first slot and a second slot that communicate with each other. The first shaft is in sliding fit with the first slot, and the second shaft is in sliding fit with the second slot;

[0008] During the process of the door body being opened from the closed state to the maximum angle, the first shaft can slide relative to the first slot, so that the first shaft first moves away from and then approaches the front wall to form a first trajectory, the first shaft reciprocates in moving away from and approaching the front wall to form a second trajectory, and the first shaft approaches the front wall to move to form a third trajectory; the second shaft can slide relative to the second slot, so that the second shaft moves away from the front wall direction to form a fourth trajectory, and the second shaft approaches the front wall to move to form a fifth trajectory;

[0012] According to an embodiment of the present application, when the first shaft moves along the first trajectory and the second trajectory, the second shaft moves along the fourth trajectory; when the second shaft moves along the fifth trajectory, the first shaft moves along the third trajectory.

[0013] According to an embodiment of the present application, during the process of the door body being opened from the closed state to the first angle, the virtual rotation center of the door body and the side wall are respectively located on both sides of the connection line of the axis centers of the first shaft and the second shaft;

[0014] During the process of the door body being opened from the first angle to the third angle, the virtual rotation center of the door body and the side wall are located on the same side of the connection line of the axis centers of the first shaft and the second shaft;

[0015] During the process of the door body being opened from the third angle to the maximum angle, the virtual rotation center of the door body and the side wall are respectively located on both sides of the connection line of the axis centers of the first shaft and the second shaft;

[0016] Among them, the third angle is the angle of the door body when the first shaft retracts to the limit.

[0017] According to an embodiment of the present application, when the relative angle between the door body and the main body is the first angle and the third angle, the virtual rotation center of the door body is located at the axis center of the first shaft.

[0018] According to an embodiment of the present application, the first angle is 30° - 70°, the second angle is 70° - 110°, the third angle is 60° - 100°, and the maximum angle is 115° - 125°.

[0019] According to an embodiment of the present application, when the relative angle between the door body and the main body is 90°, the included angle between the connection line of the axis centers of the first shaft and the second shaft and the front wall of the door body is -75° to -45°.

[0048] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as a limitation to the present application.

[0049] With the development of society and the gradual improvement of living quality, people's demand for the installation aesthetics of household refrigeration equipment has become increasingly prominent. Embedding the refrigeration equipment into the cabinet, that is, forming an embedded refrigeration equipment to achieve the unified decoration style of the home improvement method has become popular.

[0050] However, in the related art, for the refrigeration equipment installed in an embedded manner, in order to ensure that the door body can be opened smoothly, a double-axis double-groove hinge is generally used, but the double-axis double-groove hinge has a complex structure and occupies a large space.

[0051] Based on the above considerations, the present application proposes a refrigeration equipment, in which the layout of the hinge assembly is compact and occupies a small space. While enabling the door body of the embedded refrigeration equipment to be opened smoothly, the thickness of the door body can be made thinner, thereby increasing the capacity of the refrigeration equipment.

[0052] Next, refer to Figures 1 - 20 to describe the refrigeration equipment according to the embodiments of the present application.

[0053] Please refer to Figure 1 , the refrigeration equipment 1 of the embodiment of the present application includes a main body 11, a door body 12 and a hinge assembly 13.

[0054] First of all, it should be noted that the refrigeration equipment 1 can be installed in an embedded manner in the surrounding environment member. The surrounding environment member can be a cabinet, a wall or other adjacent electrical appliances, etc., which are not specifically limited here. In the subsequent writing and drawings, the cabinet body of the cabinet is taken as an example of the surrounding environment member.

[0055] The main body 11 is provided with an accommodation space for accommodating and placing items, and an opening communicating with the accommodation space is provided on the front side of the main body 11. 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 accommodation space and provide a stable accommodation space for the items.

[0056] Please refer to Figures 2 - 4 , the door body 12 includes a side wall 122 and a front wall 121 arranged at an angle. Among them, taking the side of the door body 12 facing away from the main body 11 as the front side, 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 environmental components is the side part, the side wall 122 of the door body 12 is located on the side part 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 here that both sides in the width direction of the door body 12 of a single-door refrigerator may be close to the surrounding environmental components. 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.

[0057] 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 are rotationally matched. 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 to realize the opening and closing of the door body 12.

[0058] The first hinge member 131 is fixedly provided with a first shaft 1311 and a second shaft 1312. The second hinge member 132 includes a first groove 1321 and a second groove 1322 that communicate with each other. The first shaft 1311 is slidably matched with the first groove 1321, and the second shaft 1312 is slidably matched with the second groove 1322.

[0059] The first hinge member 131 may include a mounting seat. The mounting seat is fixedly installed on the main body 11. The first shaft 1311 and the second shaft 1312 are arranged at intervals on the side of the mounting seat facing the door body 12. The second hinge member 132 is arranged on the door body 12. The second hinge member 132 is provided with a first groove 1321 and a second groove 1322 that communicate with each other. The mutually communicating first groove 1321 and second groove 1322 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. Moreover, the minimum distance between the first shaft 1311 and the second groove 1322 and the minimum distance between the second shaft 1312 and the first groove 1321 can be smaller, so that the layout of the entire hinge assembly 13 is more compact, which is convenient for reducing the space occupied by the entire hinge assembly 13.

[0060] During the opening or closing process of 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 to restrict the movement trajectory of the door body 12, so that the door body 12 has a tendency to move inward, thereby avoiding collision interference between the door body 12 and the main body 11 or the surrounding environmental components during the movement process.

[0061] Please refer to Figure 5 and Figure 6, wherein, when the door body 12 is in the closed state, the distance A0 between the axis center of the first shaft 1311 and the front wall 121 is 10 mm - 20 mm, the distance B0 between the axis center of the first shaft 1311 and the side wall 122 is 17 mm - 27 mm, the distance C0 between the axis center of the second shaft 1312 and the front wall 121 is 6 mm - 16 mm, and the distance D0 between the axis center of the second shaft 1312 and the side wall 122 is 30 mm - 40 mm.

[0062] By defining the arrangement positions of the first shaft 1311 and the second shaft 1312 relative to the door body 12 when the door body 12 is in the closed state, the distances from the first shaft 1311 and the second shaft 1312 to the front wall 121 and the side wall 122 are small. 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 small, and the matching dimensions between the hinge assembly 13 and the door body 12 are more compact, which is convenient for reducing the thickness of the door body 12.

[0063] Wherein, the distance A0 between the axis center of the first shaft 1311 and the front wall 121 refers to the length of the perpendicular line drawn from the axis center of the first shaft 1311 to the front wall 121. The value range of A0 is [10 mm, 20 mm]. Exemplarily, A0 can take values such as 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 19 mm, 19.5 mm, 20 mm or other values between 10 mm - 20 mm, and no specific limitation is made here.

[0064] The distance B0 between the axis center of the first shaft 1311 and the side wall 122 refers to the length of the perpendicular line drawn from the axis center of the first shaft 1311 to the side wall 122. The value range of B0 is [17 mm, 27 mm]. Exemplarily, B0 can take values such as 17 mm, 19 mm, 20 mm, 20.7 mm, 22 mm, 24 mm, 26 mm, 27 mm or other values between 17 mm - 27 mm, and no specific limitation is made here.

[0065] The distance C0 between the axis center of the second shaft 1312 and the front wall 121 refers to the length of the perpendicular line drawn from the axis center of the second shaft 1312 to the front wall 121. The value range of C0 is [6 mm, 16 mm]. Exemplarily, C0 can take values such as 6 mm, 8 mm, 10 mm, 11.7 mm, 12 mm, 14 mm, 16 mm or other values between 6 mm - 16 mm, and no specific limitation is made here.

[0066] The distance D0 between the axis of the second shaft 1312 and the side wall 122 refers to the length of the perpendicular line drawn from the axis of the second shaft 1312 to the side wall 122. The value range of D0 is [30mm, 40mm]. Exemplarily, D0 can take values such as 30mm, 32mm, 34mm, 34.5mm, 36mm, 38mm, 40mm or other values between 30mm - 40mm, and no specific limitation is made here.

[0067] According to the refrigeration device 1 of the embodiment of the present application, by providing the mutually connected first groove 1321 and second groove 1322, the distance between the first groove 1321 and the second groove 1322 is shortened, and the occupied space volume of the first groove 1321 and the second groove 1322 is reduced. When the door body 12 is in the closed state, the distances between the first shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 are smaller, that is, the arrangements of the first shaft 1311 and the second shaft 1312, the first groove 1321 and the second groove 1322 are relatively compact. Thus, on the premise of ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner to meet the ultra-thin door requirement of the refrigeration device 1.

[0068] Please refer to Figure 7 , according to some embodiments of the present application, when the door body 12 is in the closed state, the included angle α0 between the connection line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 of the door body 12 is 15° - 45°.

[0069] By limiting the included angle between the connection line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 of the door body 12, it is convenient to control the movement trajectory when the door body 12 starts to rotate from the closed state, and avoid interference between the door body 12 and the surrounding environmental components when the door body 12 is opened.

[0070] When the door body 12 is in the closed state, the value range of the included angle α0 between the connection line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 is [15°, 45°]. Exemplarily, α0 can take values such as 15°, 20°, 25°, 29.6°, 35°, 40°, 45° or other angles between 15° - 45°, and no specific limitation is made here.

[0071] Please refer to Figure 6 , according to some embodiments of the present application, when the door body 12 is in the closed state, the interval W0 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the thickness direction of the door body 12 is 0 - 10mm, and the interval M0 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the width direction of the door body 12 is 5 - 15mm.

[0072] By limiting the interval W0 between the axis center of the first shaft 1311 and the axis center of the second shaft 1312 in the thickness direction of the door body 12, and the interval M0 between the axis center of the first shaft 1311 and the axis center of the second shaft 1312 in the width direction of the door body 12, the distance between the first shaft 1311 and the second shaft 1312 is constrained, so that the layout of the first shaft 1311 and the second shaft 1312 is compact and the occupied space is reduced.

[0073] Among them, the value range of the interval W0 between the axis center of the first shaft 1311 and the axis center of the second shaft 1312 in the thickness direction of the door body 12 is [0, 10 mm]. Exemplarily, W0 can take values of 0, 1 mm, 2 mm, 4 mm, 6 mm, 7.8 mm, 8 mm, 10 mm or other values between 0 - 10 mm, and no specific limitation is made here.

[0074] The value range of the interval M0 between the axis center of the first shaft 1311 and the axis center of the second shaft 1312 in the width direction of the door body 12 is [5 mm, 15 mm]. Exemplarily, M0 can take values of 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, 13.7 mm, 15 mm or other values between 5 - 15 mm, and no specific limitation is made here.

[0075] Please refer to Figure 7 , according to some embodiments of the present application, when the door body 12 is opened from the closed state, the included angle β0 between the tangent of the moving direction of the first shaft 1311 relative to the first groove 1321 and the front wall 121 is 20° - 40°, and the included angle γ0 between the tangent of the moving direction of the second shaft 1312 relative to the second groove 1322 and the front wall 121 is 40° - 60°. When the door body 12 is opened from the closed state, the included angle θ0 between the tangent of the moving direction of the first shaft 1311 relative to the first groove 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second groove 1322 is 20° - 40°.

[0076] By limiting the included angles β0 and γ0 between the tangents of the moving directions of the first shaft 1311 and the second shaft 1312 relative to the front wall 121 when the door body 12 is opened from the closed state, and the included angle θ0 between the tangents of the moving directions of the first shaft 1311 and the second shaft 1312 relative to the door body 12, the moving trajectory when the door body 12 is opened is constrained, and interference between the door body 12 and the surrounding environmental components is avoided.

[0077] Among them, the value range of β0 is [20°, 40°]. Exemplarily, β0 can take values of 20°, 22°, 25°, 28.7°, 30°, 32°, 35°, 40° or other values between 20° - 40°, and no specific limitation is made here.

[0078] The value range of γ0 is [40°, 60°]. Exemplarily, γ0 can take values such as 40°, 42°, 45°, 50°, 52.8°, 55°, 57°, 60° or other values between 40° and 60°, and specific limitations are not made here.

[0079] The value range of θ0 is [20°, 40°]. Exemplarily, θ0 can take values such as 20°, 22°, 25°, 28.7°, 30°, 32°, 35°, 40° or other values between 20° and 40°, and specific limitations are not made here.

[0080] According to some embodiments of the present application, when the door body 12 is in the closed state, the first shaft 1311 is spaced from the end of the first groove 1321, and / or the second shaft 1312 is spaced from the end of the second groove 1322.

[0081] By spacing at least one of the first shaft 1311 and the second shaft 1312 from the ends of the corresponding first groove 1321 and second groove 1322, when the door body 12 is in the closed state, a certain negative closing angle can be achieved to ensure the sealing performance when the door body 12 is closed.

[0082] Please refer to Figure 6 and Figure 7 , according to some embodiments of the present application, the first end of the first groove 1321 is communicated with the second groove 1322, and the first end of the second groove 1322 is spaced from the first end of the first groove 1321. When the door body 12 is in the closed state, the first shaft 1311 is located at the first end of the first groove 1321, and the second shaft 1312 is located at the first end of the second groove 1322.

[0083] 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 the closed state, the first shaft 1311 is located at the first end of the first groove 1321, and the second shaft 1312 is located at the first end of the second groove 1322. The first end of the first groove 1321 is communicated with the middle of the second groove 1322, so that the starting position of the first shaft 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.

[0084] Please refer to 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 less than the distance between the axis center of the first shaft 1311 and the axis center of the second shaft 1312.

[0085] By setting the axial center distance between the first shaft 1311 and the second shaft 1312 to be greater than the distance between the first end of the first groove 1321 and the first end of the second groove 1322, when the first shaft 1311 and the second shaft 1312 are in the starting position, they are respectively located in the first groove 1321 and the second groove 1322. When the door body 12 is closed, the first shaft 1311 will not enter the second groove 1322, improving the working stability of the hinge assembly 13.

[0086] Please refer to Figure 4 、 Figure 8 and Figure 9 , according to some embodiments of the present application, the side wall 122 intersects the front wall 121 at the first edge 123. When the first edge 123 is in the first position, the distance A1 between the axial center of the first shaft 1311 and the front wall 121 is 13 mm - 23 mm, the distance B1 between the axial center of the first shaft 1311 and the side wall 122 is 9 mm - 19 mm, the distance C1 between the axial center of the second shaft 1312 and the front wall 121 is 19 mm - 29 mm, the distance D1 between the axial center of the second shaft 1312 and the side wall 122 is 22 mm - 32 mm. The first position represents the position where the distance between the first edge and the surrounding environmental parts is the smallest.

[0087] The side wall 122 intersects the front wall 121 at the first edge 123. During the process of the door body 12 being opened from the closed state to 90°, the first edge 123 is the part with the smallest distance between the entire door body 12 and the surrounding environmental parts. When the first edge 123 rotates to the first position, the distance between the first edge 123 and the surrounding environmental parts is the smallest, that is, the probability of interference between the door body 12 and the surrounding environmental parts is the greatest at this position. By limiting the distances between the first shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 at this position, the maximum over-box amount during the process of the door body 12 being opened to 90° is controlled. When the distance between the embedded refrigeration device 1 and the surrounding environmental parts is very small, the door body 12 can also be smoothly opened without interfering with the surrounding environmental parts.

[0088] Here, 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 surface 111 of the main body 11 during the rotation of the door body 12. The over-box amount affects the interference situation between the door body 12 and the surrounding environmental parts when the door body 12 is opened. The smaller the over-box amount, the less likely the door body 12 is to interfere with the surrounding environmental parts, and the gap between the embedded refrigeration device 1 and the surrounding environmental parts can be smaller, with better 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 environmental parts.

[0089] Moreover, when the first edge 123 is in the first position, the distances from the first axis 1311 and the second axis 1312 to the front wall 121 and the side wall 122 are small. 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 small. The mating dimensions between the hinge assembly 13 and the door body 12 are more compact, facilitating the reduction of the thickness of the door body 12.

[0090] Among them, the distance A1 between the axis center of the first axis 1311 and the front wall 121 refers to the length of the perpendicular line drawn from the axis center of the first axis 1311 to the front wall 121. The value range of A1 is [13 mm, 23 mm]. Exemplarily, A1 can take values such as 13 mm, 15 mm, 17 mm, 19 mm, 20 mm, 22 mm, 23 mm or other values between 13 mm and 23 mm, and specific limitations are not made here.

[0091] The distance B1 between the axis center of the first axis 1311 and the side wall 122 refers to the length of the perpendicular line drawn from the axis center of the first axis 1311 to the side wall 122. The value range of B1 is [9 mm, 19 mm]. Exemplarily, B1 can take values such as 9 mm, 10.8 mm, 13 mm, 15 mm, 17 mm, 18 mm, 19 mm or other values between 9 mm and 19 mm, and specific limitations are not made here.

[0092] The distance C1 between the axis center of the second axis 1312 and the front wall 121 refers to the length of the perpendicular line drawn from the axis center of the second axis 1312 to the front wall 121. The value range of C1 is [19 mm, 29 mm]. Exemplarily, C1 can take values such as 19 mm, 21 mm, 23 mm, 25 mm, 27 mm, 28.3 mm, 29 mm or other values between 19 mm and 29 mm, and specific limitations are not made here.

[0093] The distance D1 between the axis center of the second axis 1312 and the side wall 122 refers to the length of the perpendicular line drawn from the axis center of the second axis 1312 to the side wall 122. The value range of D1 is [22 mm, 32 mm]. Exemplarily, D1 can take values such as 22 mm, 23.6 mm, 26 mm, 28 mm, 30 mm, 31 mm, 32 mm or other values between 22 mm and 32 mm, and specific limitations are not made here.

[0094] According to the refrigeration device 1 of the embodiment of the present application, by providing a first groove 1321 and a second groove 1322 that are interconnected, the distance between the first groove 1321 and the second groove 1322 is shortened, and the space volume occupied by the first groove 1321 and the second groove 1322 is reduced. When the first edge 123 is in the first position, the over-box amount of the door body 12 is the largest, and the distances between the first shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 are still small. That is, the arrangement of the first shaft 1311 and the second shaft 1312, the first groove 1321 and the second groove 1322 is relatively compact. Thus, on the premise of ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner to meet the ultra-thin door requirement of the refrigeration device 1.

[0095] 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°. Exemplarily, 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°.

[0096] Please refer to Figure 8 , according to some embodiments of the present application, when the first edge 123 is in the first position, the distance between the first edge 123 and the side surface 111 of the main body 11 can be less than or equal to 3 mm.

[0097] It can be understood that the side surface 111 of the main body 11 is the surface of the main body 11 close to the surrounding environmental components. 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 out beyond the side surface 111 of the main body 11, thus there is a risk of interference with the surrounding environmental components. 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.

[0098] When the first edge 123 is in the first position, the distance between the first edge 123 and the surrounding environmental components is the smallest, that is, when the first edge 123 is at the position farthest from the side surface 111 of the main body 11. To avoid contact between the first edge 123 and the surrounding environmental components, it is defined that when the first edge 123 is in the first position, the distance between the first edge 123 and the side surface 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. Thus, as long as the distance between the refrigeration device 1 and the surrounding environmental components is at most 3 mm, the door body 12 can be smoothly opened to meet the embedded installation requirements.

[0099] Wherein, when the first edge 123 is in the first position, the value range of the distance L1 between the first edge 123 and the side surface 111 of the main body 11 is [0 mm, 3 mm]. Exemplarily, L1 can take values such as 0.5 mm, 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm or other values within 3 mm. Specific limitations are not made here.

[0100] 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 exceed the side surface 111 of the main body 11. At this time, the over-box amount of the door body 12, that is, the distance between the first edge 123 and the side surface 111 of the main body 11, is determined as a negative value. At this time, the value range of the distance L1 between the first edge 123 and the side surface 111 of the main body 11 can be [-3 mm, 0 mm]. Exemplarily, L1 can take values such as -3 mm, -2.5 mm, -2 mm, -1.5 mm, -1 mm, -0.5 mm or other values between -3 mm and 0 mm.

[0101] Please refer to Figure 8 , according to some embodiments of the present application, when the first edge 123 is in the first position, the distance L2 between the first edge 123 and the surrounding environmental component is greater than or equal to 1 mm.

[0102] By limiting the distance between the first edge 123 and the surrounding environmental component, when the first edge 123 extends the farthest distance from the side surface 111 of the main body 11, it is not easy to interfere with the surrounding environmental component. Among them, the distance L2 between the first edge 123 and the surrounding environmental component can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm or other values greater than 1 mm.

[0103] Please refer to Figure 10 , according to some embodiments of the present application, when the first edge 123 is in the first position, the included angle α1 between the connecting line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 is -51° to -21°.

[0104] During the process of the door body 12 being opened from the closed state, the included angle between the connecting line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 first decreases and then increases. Before the door body 12 is opened to the position where the first edge 123 is in the first position, there is a state where the connecting line of the axes of the first shaft 1311 and the second shaft 1312 is parallel to the front wall 121.

[0105] It should be noted here that for the convenience of distinction, when the first axis 1311 is located on the side of the second axis 1312 away from the front wall 121, the included angle between the axis connection line 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 included angle between the axis connection line of the first axis 1311 and the second axis 1312 and the front wall 121 is a negative value.

[0106] When the first edge 123 is in the first position, the value range of the included angle α1 between the axis connection line of the first axis 1311 and the second axis 1312 and the front wall 121 is [-51°, -21°]. Exemplarily, α1 can take values such as -51°, -45°, -40°, -36.3°, -30°, -25°, -21° or other angles between -51° and -21°, and no specific limitation is made here.

[0107] Please refer to 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 satisfy:

[0108] E1 - B0 ≤ 3.1 mm.

[0109] It can be understood that when the door body 12 is in the closed state, the side wall 122 is flush with the side surface 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 environmental components. When the door body 12 rotates to the first edge 123 in the first position, the risk of interference between the first edge 123 and the surrounding environmental components is the highest. By limiting E1 - B0 ≤ 3.1 mm, the size of the first edge 123 exceeding the side surface 111 of the main body 11 is controlled, ensuring that the refrigeration device 1 can be better used in an embedded manner.

[0110] Among them, E1 - B0 can take values such as 1.1 mm, 1.6 mm, 2.1 mm, 2.6 mm, 3.1 mm or other values less than 3.1 mm.

[0111] In another example, when the first edge 123 is in the first position, the first edge 123 may not exceed the side surface 111 of the main body 11, that is, the over-box amount during the rotation of the door body 12 is 0. At this time, the distance E1 from the axis center of the first axis 1311 to the first edge 123 is less than B0, and E1 - B0 can be 0 or a negative value.

[0112] Please refer to Figure 9, according to some embodiments of the present application, when the first edge 123 is in the first position, the distance W1 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the thickness direction of the door body 12 is 5 mm - 15 mm, and the distance M1 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the width direction of the door body 12 is 5 mm - 15 mm.

[0113] By defining the distance W1 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the thickness direction of the door body 12, and the distance M1 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the width direction of the door body 12, the distance between the first shaft 1311 and the second shaft 1312 is restricted, making the layout of the first shaft 1311 and the second shaft 1312 compact and reducing the occupied space.

[0114] Among them, the value range of the distance W1 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the thickness direction of the door body 12 is [5 mm, 15 mm]. Exemplarily, W1 can take values such as 5 mm, 7 mm, 7.8 mm, 9 mm, 10 mm, 12 mm, 15 mm or other values between 5 mm - 15 mm, and no specific limitation is made here.

[0115] The value range of the distance M1 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the width direction of the door body 12 is [5 mm, 15 mm]. Exemplarily, M1 can take values such as 5 mm, 7 mm, 9 mm, 10 mm, 12 mm, 13.7 mm, 15 mm or other values between 5 mm - 15 mm, and no specific limitation is made here.

[0116] Please refer to Figure 10 , according to some embodiments of the present application, when the first edge 123 moves to the first position, the included angle β1 between the tangent of the moving direction of the first shaft 1311 relative to the first groove 1321 and the front wall 121 is -25° to -45°, the included angle γ1 between the tangent of the moving direction of the second shaft 1312 relative to the second groove 1322 and the front wall 121 is 50° to 70°, and the included angle θ1 between the tangent of the moving direction of the first shaft 1311 relative to the first groove 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second groove 1322 is 75° to 115°.

[0117] It should be noted here that for the sake of distinction, when the moving directions of the first shaft 1311 and the second shaft 1312 are away from the front wall 121, the included angle between the tangent of the moving direction of the shaft relative to the groove and the front wall 121 is positive.

[0118] By limiting the included angles between the tangents of the moving directions of the first axis 1311 and the second axis 1312 relative to the door body 12 and the front wall 121 when the first edge 123 moves to the first position, and the included angle between the tangents of the moving directions of the first axis 1311 and the second axis 1312 relative to the door body 12, it is to constrain the moving direction of the first edge 123 when the door body 12 continues to rotate to move away from the surrounding environmental components, so as to avoid interference caused by the distance between the first edge 123 and the surrounding environmental components being too close.

[0119] Among them, the value range of β1 is [-25°, -45°]. Exemplarily, β1 can take values such as -25°, -30°, -35°, -38.8°, -40°, -45°, or other angles between -25° and -45°, and specific limitations are not made here.

[0120] The value range of γ1 is [50°, 70°]. Exemplarily, γ1 can take values such as 50°, 55°, 60°, 63.2°, 65°, 70°, or other angles between 50° and 70°, and specific limitations are not made here.

[0121] The value range of θ1 is [75°, 115°]. Exemplarily, θ1 can take values such as 75°, 80°, 90°, 102°, 110°, 115°, or other angles between 75° and 115°, and specific limitations are not made here.

[0122] Please refer to 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 12 mm - 22 mm, the distance B2 between the axis center of the first axis 1311 and the side wall 122 is 9 mm - 19 mm, the distance C2 between the axis center of the second axis 1312 and the front wall 121 is 28 mm - 38 mm, and the distance D2 between the axis center of the second axis 1312 and the side wall 122 is 17 mm - 27 mm.

[0123] 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 distances between the first axis 1311 and the second axis 1312 and the front wall 121 and the side wall 122 at this position, when the door body 12 is opened to 90° and the distance between the embedded refrigeration device 1 and the surrounding environmental components is very small, it is to control the relative position of the door body 12 so that the over - box amount is not too large and the intrusion amount is not too large, which is convenient for users to use when the door body 12 is normally opened.

[0124] Moreover, when the relative angle between the door body 12 and the main body 11 is 90°, the distances from the first shaft 1311 and the second shaft 1312 to the front wall 121 and the side wall 122 are small. While the structure of the hinge assembly 13 itself is compact, the distances between the hinge assembly 13 and the front wall 121 and the side wall 122 are also small. The matching dimensions between the hinge assembly 13 and the door body 12 are more compact, facilitating the reduction of the thickness of the door body 12.

[0125] Among them, the distance A2 between the axis center of the first shaft 1311 and the front wall 121 refers to the length of the perpendicular line drawn from the axis center of the first shaft 1311 to the front wall 121. The value range of A2 is [12 mm, 22 mm]. Exemplarily, A2 can take values such as 12 mm, 14 mm, 16 mm, 18 mm, 19.5 mm, 20 mm, 22 mm or other values between 12 mm and 22 mm, and no specific limitation is made here.

[0126] The distance B2 between the axis center of the first shaft 1311 and the side wall 122 refers to the length of the perpendicular line drawn from the axis center of the first shaft 1311 to the side wall 122. The value range of B2 is [9 mm, 19 mm]. Exemplarily, B2 can take values such as 9 mm, 11 mm, 11.2 mm, 13 mm, 15 mm, 17 mm, 19 mm or other values between 9 mm and 19 mm, and no specific limitation is made here.

[0127] The distance C2 between the axis center of the second shaft 1312 and the front wall 121 refers to the length of the perpendicular line drawn from the axis center of the second shaft 1312 to the front wall 121. The value range of C2 is [28 mm, 38 mm]. Exemplarily, C2 can take values such as 28 mm, 30 mm, 32 mm, 34 mm, 34.5 mm, 36 mm, 38 mm or other values between 28 mm and 38 mm, and no specific limitation is made here.

[0128] The distance D2 between the axis center of the second shaft 1312 and the side wall 122 refers to the length of the perpendicular line drawn from the axis center of the second shaft 1312 to the side wall 122. The value range of D2 is [17 mm, 27 mm]. Exemplarily, D2 can take values such as 17 mm, 20 mm, 21 mm, 22 mm, 23 mm, 25 mm, 27 mm or other values between 17 mm and 27 mm, and no specific limitation is made here.

[0129] According to the refrigeration device 1 of the embodiment of the present application, by providing a first groove 1321 and a second groove 1322 that are interconnected, the distance between the first groove 1321 and the second groove 1322 is shortened, the space volume occupied by the first groove 1321 and the second groove 1322 is reduced, and when the relative angle between the door body 12 and the main body 11 is 90°, the distances between the first shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 are still small, that is, the arrangements of the first shaft 1311 and the second shaft 1312, the first groove 1321 and the second groove 1322 are relatively compact. Therefore, on 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 requirement of the refrigeration device 1.

[0130] Please refer to 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.

[0131] The intrusion amount of the door body 12 is the intrusion amount of the door body 12 relative to the side surface 111 of the main body 11 towards 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 the use. For example, when there is a drawer in the refrigeration device 1, there is a use scenario of pulling the drawer. The smaller the intrusion amount of the door body 12, the smaller the probability of interference between the drawer and the door body 12, and at the same time, the drawer can be made wider to increase the accommodation space.

[0132] 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 the closed state, the door seal 14 is clamped between the rear wall 124 and the main body 11, playing a 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 surface of the door seal 14 away from the door body 12 and the side surface 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 surface of the door seal 14 away from the door body 12 and the side surface 111 of the main body 11.

[0133] In the related art, in order to make the door body avoid the surrounding environmental components, generally, the large lateral movement distance of the door body results in a large intrusion amount, which has a great impact on the internal design of the refrigeration device. For example, it is necessary to reduce the width of the drawer to facilitate the pulling and use of the drawer. In the present application, by limiting the intrusion amount of the door body 12 to be less than or equal to 63 mm, the intrusion amount of the door body 12 is controlled within a small range, thereby improving the use experience.

[0134] Exemplarily, the intrusion amount H1 of the door body 12 can take values of 63 mm, 60 mm, 59 mm, 57 mm, 56.5 mm, 56.4 mm or other values less than 63 mm.

[0135] 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.

[0136] Please refer to 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.

[0137] 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 surface 111 of the main body 11. Since the surrounding environmental components need to be avoided during the opening process of the door body 12, the entire door body 12 will move towards 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 of the side surface 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 surface 111 of the main body 11 is the inward movement amount of the door body 12. By limiting the inward movement amount, the occupation of the use space by the door body 12 can be reduced, the drawer can be made larger, and the aesthetics is higher.

[0138] Among them, F can take values of 3 mm, 2.5 mm, 2 mm, 1.5 mm, 1 mm, 0.5 mm or other values less than 3 mm, and no specific limitation is made here.

[0139] Please refer to Figure 6 and Figure 12 , according to some embodiments of the present application, when the door body 12 is in the closed state, the distance A0 between the axis center of the first shaft 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 shaft 1311 and the side wall 122 can satisfy:

[0140] -3 mm ≤ B2 - A0 ≤ 3 mm.

[0141] 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 surface 111 of the main body 11. Therefore, the distance between the axis center of the first shaft 1311 and the side wall 122 at this time is the distance between the axis center of the first shaft 1311 and the side surface 111 of the main body 11; when the relative angle between the door body 12 and the main body 11 is 90°, at this time the side wall 122 rotates to be perpendicular to the side surface 111 of the main body 11, and the front wall 121 is parallel to the main body 11. Since the first shaft 1311 is relatively fixed to the main body 11, the vertical distance between the front wall 121 and the side surface 111 of the main body 11 in the state where the door body 12 is opened to 90° can be deduced from the distance between the axis center of the first shaft 1311 and the front wall 121, and then the intrusion amount of the door body 12 in the 90° state can be judged.

[0142] By limiting -3mm ≤ B2 - A0 ≤ 3mm, the intrusion amount of the door body 12 is controlled within a very small range, thereby improving the use experience of the refrigeration device 1.

[0143] Among them, B2 - A0 can take values of -3mm, -2mm, -1mm, 0mm, 1mm, 2mm, 3mm or other values between -3mm and 3mm, and no specific limitation is made here.

[0144] Please refer to 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 included angle between the connection line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 of the door body 12 is -75° to -45°.

[0145] During the process of the door body 12 being opened from the closed state, the included angle between the connection line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 first decreases and then increases. Before the door body 12 is opened to a relative angle of 90° with the main body 11, there is a state where the connection line of the axes of the first shaft 1311 and the second shaft 1312 is parallel to the front wall 121.

[0146] When the relative angle between the door body 12 and the main body 1 is 90°, the value range of the included angle α2 between the connection line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 is [-75°, -45°]. Exemplarily, α2 can take values of -75°, -70°, -65°, -60.4°, -55°, -50°, -45° or other angles between -75° and -45°, and no specific limitation is made here.

[0147] Please refer to 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 interval W2 in the thickness direction of the door body 12 between the axis of the first shaft 1311 and the axis of the second shaft 1312 is 5mm - 15mm, and the interval M2 in the width direction of the door body 12 between the axis of the first shaft 1311 and the axis of the second shaft 1312 is 5mm - 15mm.

[0148] By limiting the interval W2 in the thickness direction of the door body 12 between the axis of the first shaft 1311 and the axis of the second shaft 1312, and the interval M2 in the width direction of the door body 12 between the axis of the first shaft 1311 and the axis of the second shaft 1312, the distance between the first shaft 1311 and the second shaft 1312 is restricted, making the layout of the first shaft 1311 and the second shaft 1312 compact and reducing the occupied space.

[0149] Among them, the value range of the interval W1 between the axis center of the first shaft 1311 and the axis center of the second shaft 1312 in the thickness direction of the door body 12 is [5 mm, 15 mm]. Exemplarily, W2 can take values such as 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, 13.7 mm, 15 mm or values between 5 mm and 15 mm, and no specific limitation is made here.

[0150] The value range of the interval M1 between the axis center of the first shaft 1311 and the axis center of the second shaft 1312 in the width direction of the door body 12 is [5 mm, 15 mm]. Exemplarily, M2 can take values such as 5 mm, 7 mm, 7.8 mm, 9 mm, 11 mm, 13 mm, 15 mm or values between 5 mm and 15 mm, and no specific limitation is made here.

[0151] Please refer to Figure 13 , according to some embodiments of the present application, when the door body 12 is opened to 90°, the included angle β2 between the tangent of the moving direction of the first shaft 1311 relative to the first groove 1321 and the front wall 121 is -25° to -45°, the included angle γ2 between the tangent of the moving direction of the second shaft 1312 relative to the second groove 1322 and the front wall 121 is 5° to 25°, and the included angle θ2 between the tangent of the moving direction of the first shaft 1311 relative to the first groove 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second groove 1322 is 30° to 70°.

[0152] By limiting the included angles β2 and γ2 between the tangents of the moving directions of the first shaft 1311 and the second shaft 1312 relative to the front wall 121 when the door body 12 is opened to 90°, and the included angle θ2 between the tangents of the moving directions of the first shaft 1311 and the second shaft 1312 relative to the door body 12, the attitude of the door body 12 when it continues to rotate is restricted, avoiding direct interference between the door body 12 and the surrounding environmental components, and enabling the door body 12 to be opened to a larger angle.

[0153] Among them, the value range of β2 is [-25°, -45°]. Exemplarily, β2 can take values such as -25°, -30°, -34.9°, -40°, -45° or other angles between -25° and -45°, and no specific limitation is made here.

[0154] The value range of γ2 is [5°, 25°]. Exemplarily, γ can take values such as 5°, 10°, 15°, 17.1°, 20°, 25° or other angles between 5° and 25°, and no specific limitation is made here.

[0155] The value range of θ2 is [30° to 70°]. Exemplarily, θ2 can take values of 30°, 35°, 40°, 45°, 50°, 52°, 60°, 70° or other angles between 30° and 70°, which are not specifically limited herein.

[0156] Please refer to 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 of the first shaft 1311 and the front wall 121 is 7 mm - 17 mm, the distance B3 between the axis of the first shaft 1311 and the side wall 122 is 4.5 mm - 14.5 mm, the distance C3 between the axis of the second shaft 1312 and the front wall 121 is 21 mm - 31 mm, and the distance D3 between the axis of the second shaft 1312 and the side wall 122 is 4 mm - 14 mm.

[0157] It can be understood that the maximum relative angle between the door body 12 and the main body 11 means that the door body 12 is opened to the maximum angle. 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 environmental components, the door body 12 can continue to be opened to the maximum angle for the convenience of users. By limiting the distances between the first shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 at this position, the attitude 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 device 1 and the surrounding environmental components is very small, it is ensured that the maximum angle is sufficient for users to use.

[0158] Moreover, when the relative angle between the door body 12 and the main body 11 is the largest, the distances from the first shaft 1311 and the second shaft 1312 to the front wall 121 and the side wall 122 are relatively small. While the hinge assembly 13 has a compact structure itself, the distances between the hinge assembly 13 and the front wall 121 and the side wall 122 are also relatively small, and the fitting dimensions between the hinge assembly 13 and the door body 12 are more compact, which is convenient for reducing the thickness of the door body 12.

[0159] Among them, the distance A3 between the axis of the first shaft 1311 and the front wall 121 refers to the length of the perpendicular line drawn from the axis of the first shaft 1311 to the front wall 121. The value range of A3 is [7 mm, 17 mm]. Exemplarily, A3 can take values of 7 mm, 9 mm, 11 mm, 11.6 mm, 13 mm, 15 mm, 17 mm or other values between 7 mm and 17 mm, which are not specifically limited herein.

[0160] The distance B3 between the axis center of the first shaft 1311 and the side wall 122 refers to the length of the perpendicular line drawn from the axis center of the first shaft 1311 to the side wall 122. The value range of B3 is [4.5 mm, 14.5 mm]. Exemplarily, B3 can take values such as 4.5 mm, 6 mm, 8 mm, 9.7 mm, 12 mm, 14 mm, 14.5 mm or other values between 4.5 mm and 14.5 mm, and no specific limitation is made here.

[0161] The distance C3 between the axis center of the second shaft 1312 and the front wall 121 refers to the length of the perpendicular line drawn from the axis center of the second shaft 1312 to the front wall 121. The value range of C3 is [21 mm, 31 mm]. Exemplarily, C3 can take values such as 21 mm, 23 mm, 25 mm, 27 mm, 27.4 mm, 29 mm, 31 mm or other values between 21 mm and 31 mm, and no specific limitation is made here.

[0162] The distance D3 between the axis center of the second shaft 1312 and the side wall 122 refers to the length of the perpendicular line drawn from the axis center of the second shaft 1312 to the side wall 122. The value range of D3 is [4 mm, 14 mm]. Exemplarily, D3 can take values such as 4 mm, 6 mm, 8 mm, 9.6 mm, 10 mm, 12 mm, 14 mm or other values between 4 mm and 14 mm, and no specific limitation is made here.

[0163] According to the refrigeration device 1 of the embodiment of the present application, by providing the mutually connected first groove 1321 and second groove 1322, the distance between the first groove 1321 and the second groove 1322 is shortened, the occupied space volume of the first groove 1321 and the second groove 1322 is reduced. 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 distances between the first shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 are still relatively small. That is, the arrangements of the first shaft 1311 and the second shaft 1312, and the first groove 1321 and the second groove 1322 are relatively compact. Thus, on the premise of ensuring the rotation angle of the door body 12, the thickness of the door body 12 can be made thinner to meet the ultra-thin door requirement of the refrigeration device 1.

[0164] Please refer to 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 satisfy:

[0165] H1 < H2.

[0166] It can be understood that the door body 12 further includes a rear wall 124 opposite to the front wall 121. The rear wall 124 intersects with the side walls 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 towards the opening center of the main body 11. And when the relative angle between the door body 12 and the main body 11 is at its maximum, the second edge 125 is the part of the entire door body 12 closest to the opening center of the main body 11. That is, at this time, the distance between the second edge 125 and the side surface 111 of the main body 11 is the intrusion amount of the door body 12.

[0167] It can be understood that when a general user uses the refrigeration device 1, the most common usage state is to open the door body 12 to 90°. Therefore, the internal design of the refrigeration device 1 ensures that items can be normally taken and placed when the door body 12 is opened to 90°. For example, when there is a drawer in the refrigeration device 1, the door body 12 will not affect the pulling and pushing 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 at its maximum, it will not affect the normal use of the refrigeration device 1 either. For example, it will not affect the normal pulling and pushing of the drawer.

[0168] Please refer to 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 at its maximum, the intrusion amount H2 of the door body 12 is less than or equal to 63 mm.

[0169] In the related art, in order to make the door body avoid the surrounding environmental components, the general intrusion amount is relatively large, which has a great impact on the internal design of the refrigeration device. For example, it is necessary to reduce the width of the drawer to facilitate the pulling and pushing of the drawer. The present 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 at its maximum, so as to control the intrusion amount of the door body 12 within a very small range, with little impact on the use of the refrigeration device 1 and improving the user experience.

[0170] Exemplarily, the intrusion amount H2 of the door body 12 can take values such as 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 herein.

[0171] Please refer to 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 at its maximum, the included angle α3 between the connection line of the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 is -105° to -75°.

[0172] During the process of the door body 12 being opened from 90° to the maximum angle, the included angle between the axis connection line of the first shaft 1311 and the second shaft 1312 and the front wall 121 gradually increases. When the door body 12 is opened to the maximum angle, the value range of the included angle α3 between the axis connection line of the first shaft 1311 and the second shaft 1312 and the front wall 121 is [-105°, -75°]. Exemplarily, α3 can take values of -105°, -100°, -95°, -90.4°, -85°, -80°, -75° or other angles between -105° and -75°, and no specific limitation is made here.

[0173] Please refer to 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 of the first shaft 1311 and the axis of the second shaft 1312 in the thickness direction of the door body 12 is 10 mm - 25 mm, and the distance between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the width direction of the door body 12 is 0 - 5 mm.

[0174] By limiting the distance between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the thickness direction of the door body 12, and the distance between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the width direction of the door body 12, to restrict the distance between the first shaft 1311 and the second shaft 1312, making the layout of the first shaft 1311 and the second shaft 1312 compact and reducing the occupied space.

[0175] Among them, the value range of the distance W3 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the thickness direction of the door body 12 is [10 mm, 25 mm]. Exemplarily, W3 can take values of 10 mm, 12 mm, 14 mm, 15.8 mm, 18 mm, 20 mm, 22 mm, 25 mm or other values between 10 mm and 25 mm, and no specific limitation is made here.

[0176] The value range of the distance M3 between the axis of the first shaft 1311 and the axis of the second shaft 1312 in the width direction of the door body 12 is [0, 5 mm]. Exemplarily, M3 can take values of 0 mm, 0.1 mm, 0.2 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm or other values between 0 and 5 mm, and no specific limitation is made here.

[0177] Please refer to Figure 16, according 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 included angle β3 between the tangent of the moving direction of the first shaft 1311 relative to the first groove 1321 and the front wall 121 is -120° to -140°, the included angle γ3 between the tangent of the moving direction of the second shaft 1312 relative to the second groove 1322 and the front wall 121 is -55° to -75°, and the included angle θ3 between the tangent of the moving direction of the first shaft 1311 relative to the first groove 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second groove 1322 is 50° to 70°.

[0178] By defining the included angles β3 and γ3 between the tangents of the moving directions of the first shaft 1311 and the second shaft 1312 relative to the front wall 121 when the door body 12 is opened to the maximum angle, and the included angle θ3 between the tangents of the moving directions of the first shaft 1311 and the second shaft 1312, the stability of the door body 12 when rotating to the maximum angle is constrained, and the intrusion amount of the door body 12 is controlled.

[0179] Among them, the value range of β3 is [-120°, -140°]. Exemplarily, β3 can take values of -120°, -125°, -129°, -133°, -135°, -140° or other angles between -120° and -140°, and no specific limitation is made here.

[0180] The value range of γ3 is [-55°, -75°]. Exemplarily, γ3 can take values of -55°, -60°, -65°, -67°, -70°, -75° or other angles between -55° and -75°, and no specific limitation is made here.

[0181] The value range of θ3 is [50° to 70°]. Exemplarily, θ3 can take values of 50°, 55°, 58°, 60°, 65°, 70° or other angles between 50° and 70°, and no specific limitation is made here.

[0182] 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°.

[0183] Exemplarily, the maximum relative angle between the door body 12 and the main body 11 can take values of 115°, 117°, 120°, 121°, 123°, 125° or other angles between 115° and 125°, and no specific limitation is made here.

[0184] Please refer to Figure 17 , Figure 18 , Figure 19 and Figure 20, according to some embodiments of the present application, during the process of the door body 12 being opened from the closed state to the maximum angle, the first shaft 1311 can slide relative to the first groove 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 reciprocates away from and towards the front wall 121 to form a second trajectory b, and the first shaft 1311 moves towards the front wall 121 to form a third trajectory c; the second shaft 1312 can slide relative to the second groove 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 towards the front wall 121 to form a fifth trajectory e.

[0185] Since 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 are movable relative to the door body 12 and the first groove 1321 and the second groove 1322 on the door body 12. During the process of the door body 12 being opened from the closed state to the maximum angle, the total movement trajectory of the first shaft 1311 can be sequentially divided into a first trajectory a, a second trajectory b, and a third trajectory c.

[0186] Among them, the first trajectory a includes two segments that first extend away from the front wall 121 and then extend towards the front wall 121; the second trajectory b includes two ends that first extend away from the front wall 121 and then extend towards the front wall 121, and since the first shaft 1311 reciprocates to form the second trajectory b, the two ends included in the second trajectory b overlap each other, and in the second trajectory b, a segment extending away from the front wall 121 overlaps with the first trajectory a in the trajectory path, so that when the first shaft 1311 moves along the second trajectory b, a retraction is formed in the overall movement direction; the third trajectory c extends towards the front wall 121.

[0187] It can be understood that the fourth trajectory d and the fifth trajectory e are misaligned with the first trajectory a, the second trajectory b, and the third trajectory c to avoid interference between the first shaft 1311 and the second shaft 1312, where the fourth trajectory d extends in the direction away from the front wall 121, and the fifth trajectory e extends in the direction towards the front wall 121.

[0188] By defining the movement trajectories of the first shaft 1311 and the second shaft 1312, in the initial stage when the door body 12 is opened from the closed state to the maximum angle, both the first shaft 1311 and the second shaft 1312 move in a direction away from the front wall 121, so that the door body 12 has a tendency to move in a direction away from the main body 11, to avoid interference between the door body 12 and the main body 11; in the intermediate stage when the door body 12 is opened from the closed state to the maximum angle, the first shaft 1311 forms a section of retraction in the movement direction. By setting this section of retraction, the over-box amount of the door body 12 during rotation can be effectively controlled, and in cooperation with the movement of the second shaft 1312, the door body 12 can be quickly rotated and opened, reducing the space occupied by the movement trajectory of the first shaft 1311 during the rotation of the door body 12, and further facilitating the reduction of the space occupied by the entire hinge assembly 13; in the final stage when the door body 12 is opened from the closed state to the maximum angle, both the first shaft 1311 and the second shaft 1312 move in a direction close to the front wall 121, to facilitate the large-angle opening of the door body 12.

[0189] Moreover, as can be seen from the above content, the total movement trajectories of the first shaft 1311 and the second shaft 1312 both have turning points, further reducing the space occupied by the first shaft 1311 and the second shaft 1312 in the thickness direction of the door body 12 during the relative movement with the door body 12, enabling the thickness of the door body 12 to be thinner. Not only can the mass of the door body 12 be lighter, but also the thickness distribution of the entire refrigeration device 1 can be optimized, improving the high-class sense and practicality of the refrigeration device 1.

[0190] For the refrigeration device 1 according to the embodiment of the present application, by defining the movement trajectories of the first shaft 1311 and the second shaft 1312, not only can the space occupied during the rotation of the hinge assembly 13 be reduced, facilitating the adaptation of the ultra-thin door, but it is also not easy to interfere with the surrounding environmental components, and the door body 12 of the refrigeration device 1 that can be embedded and installed can be opened at a large angle, which is convenient for users to use.

[0191] Please refer to Figures 17 - 20 , according to some embodiments of the present application, 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 second shaft 1312 moves along the fifth trajectory e, the first shaft 1311 moves along the third trajectory c.

[0192] During the movement of the first shaft 1311 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. Among them, during the movement of the first shaft 1311 along the first trajectory a, the distance between the first shaft 1311 and the front wall 121 undergoes a turning. When the first shaft 1311 moves along the second trajectory b, there is a retraction and another turning. And during the two turning processes of the movement direction of the first shaft 1311 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 first shaft 1311 and the second shaft 1312 can quickly open the door body 12 to the use opening degree within a limited movement space.

[0193] When the second shaft 1312 moves close to the front wall 121 along the fifth trajectory e, the first shaft 1311 moves close to the front wall 121 along the third trajectory c to increase the distance between the front wall 121 and the surrounding environmental components, which is convenient for the front wall 121 of the door body 12 to avoid the surrounding environmental components and achieve a large-angle opening in the embedded refrigeration device 1.

[0194] Please refer to Figure 17 , according to some embodiments of the present application, during the process of the door body 12 being opened from the closed state to the first angle, the first shaft 1311 moves along the first trajectory a and the second shaft 1312 moves along the fourth trajectory d.

[0195] The first shaft 1311 first moves away from the front wall 121 and then moves close to the front wall 121 along the first trajectory a, and the second shaft 1312 moves away from the front wall 121 along the fourth trajectory d. It can be seen that the first shaft 1311 first passes through the inflection point of the direction during the movement. The first shaft 1311 and the second shaft 1312 moving away from the front wall 121 together first can make the door body 12 as a whole move away from the main body 11 first, which is convenient for the subsequent opening process of the door body 12 and is not easy to interfere with the main body 11. Then the first shaft 1311 moves in the direction close to the front wall 121, making the instantaneous rotation center of the door body 12 quickly approach 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.

[0196] Figure 18 and [[ID= During the process of the door body 12 being opened from the first angle to the second angle, the first shaft 1311 first retracts and then makes a reciprocating movement forward along the second trajectory b, and the second shaft 1312 moves along the fourth trajectory d.

[0197] It can be 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 moves reciprocally back and forth along the second trajectory b, first moving away from the front wall 121 and then moving closer to the front wall 121. During this process, the second shaft 1312 continues to move away from the front wall 121 along the fourth trajectory d. By the retraction of the first shaft 1311, the over-box amount of the first edge 123 during the rotation of the door body 12 can be controlled, and the door body 12 can be quickly opened. Moreover, by setting the retraction movement, the space occupied by the movement trajectory of the first shaft 1311 becomes smaller. Corresponding to the door body 12, this means that the required size of the first groove 1321 becomes smaller, and the space occupied by the entire hinge assembly 13 becomes smaller.

[0198] Please refer to ​ , when the door body 12 is opened from the second angle to the maximum angle, the first shaft 1311 moves along the third trajectory c, and the second shaft 1312 moves along the fifth trajectory e.

[0199] When the door body 12 continues to open from the second angle, the first shaft 1311 moves closer to the front wall 121 along the third trajectory c, and the second shaft 1312 also moves closer to the front wall 121 along the fifth trajectory e. Correspondingly, the entire front wall 121 moves in the direction closer to the first shaft 1311 and the second shaft 1312, which can increase the distance between the front wall 121 and the surrounding environmental components. In the embedded refrigeration device 1, it is convenient for the front wall 121 of the door body 12 to avoid the surrounding environmental components and achieve large-angle opening.

[0200] According to the refrigeration device 1 provided by the embodiment of the present application, by defining the cooperation relationship between the movement trajectories of the first shaft 1311 and the second shaft 1312, not only can the space occupied during the rotation of the hinge assembly 13 be reduced, facilitating the adaptation of ultra-thin doors, but it is also not easy to interfere with the surrounding environmental components. The door body 12 of the embedded refrigeration device 1 can be opened at a large angle, which is convenient for users to use.

[0201] Please refer to ​ , according to some embodiments of the present application, the first shaft 1311 moves closer 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 then moves closer to the side wall 122 after the retraction is completed. The first shaft 1311 first moves closer to the side wall 122 along the third trajectory c and then moves away from the side wall 122; the second shaft 1312 always moves closer to the side wall 122 along the fourth trajectory d and the fifth trajectory e.

[0202] In the initial stage when the door body 12 is opened from the closed state to the maximum angle, the first shaft 1311 moves along the first trajectory a close to the side wall 122, and the second shaft 1312 moves along the fourth trajectory d close to the side wall 122, so that the door body 12 has a tendency to move towards the side close to the opening center relative to the main body 11, thereby avoiding interference between the door body 12 and the surrounding environmental components 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 shaft 1311 moves back along the second trajectory b, so that the first shaft 1311 moves away from the side wall 122, and the second shaft 131 is close to the side wall 122, to control that the over-box amount of the first edge 123 connected to the side wall 122 is not too large, meet the requirements of embedded installation, and make the door body 12 rotate quickly; in the later stage when the door body 12 is opened from the closed state to the maximum angle, the first shaft 1311 first moves close to the side wall 122 along the third trajectory c 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 shaft 1311, make the structure of the entire hinge assembly 13 more compact, and can also achieve large-angle opening for the ultra-thin door body 12, and the intrusion amount into the main body 11 is small.

Until the door body 12 is opened to the first angle, the virtual rotation center of the door body 12 is coaxial with the first shaft 1311; when the door body 12 is opened from the first angle to the third angle, the virtual rotation center of the door body 12 is located on the side of the connecting line of the axial centers of the first shaft 1311 and the second shaft 1312 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 shaft 1311 retracts to the limit position, and the virtual rotation center of the door body 12 is coaxial with the first shaft 1311; during 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 connecting line of the axial centers of the first shaft 1311 and the second shaft 1312 away from the side wall 122 again.

[0263] Please refer to ​ and ​ , According to some embodiments of the present application, during the process of the door body 12 being opened from 90° to the maximum angle, the intrusion amount of the door body 12 is less than or equal to 63 mm.

[0264] It can be understood that when the relative angle between the door body 12 and the main body 11 reaches 90°, the opening angle required for the normal use of the drawer is reached. By limiting the intrusion amount of the door body 12 during the process from 90° to the maximum opening angle to be less than or equal to 63 mm, the intrusion amount of the door body 12 can be controlled within a smaller range. While not interfering with the surrounding environmental components, the width of the drawer can be made wider, increasing the space of the drawer.

[0265] Exemplarily, during the process of the door body 12 being opened 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.

[0266] Please refer to ​ and ​ , according to some embodiments of the present application, during the process of the door body 12 being opened from 90° to the maximum angle, the inward movement amount of the door body 12 is less than or equal to 3 mm.

[0267] It can be understood that when the relative angle between the door body 12 and the main body 11 reaches 90°, the opening angle required for the normal use of the drawer is reached. By limiting the inward movement amount of the door body 12 during the process from 90° to the maximum opening angle to be less than or equal to 3 mm, the inward movement amount of the door body 12 can be controlled within a small range. Without interfering with the surrounding environmental components, the width of the drawer can be made wider, increasing the space of the drawer.

[0268] Among them, F can take values of 3 mm, 2.5 mm, 2 mm, 1.5 mm, 1 mm, 0.5 mm, or other values less than 3 mm, and no specific limitation is made here.

[0269] Please refer to ​ , ​ and ​ , according to some embodiments of the present application, during the process of the door body 12 being opened from the closed state to 90°, the amount exceeding the box of the door body 12 is less than or equal to 3 mm.

[0270] It can be understood that when the relative angle between the door body 12 and the main body 11 reaches 90°, it is the most commonly used opening angle of the door body 12. The embedded refrigeration device 1 needs to ensure that the door body 12 can be opened at least 90° without interfering with the surrounding environmental components. By limiting the amount exceeding the box of the door body 12 during the process from the closed state to 90° to be less than or equal to 3 mm, the amount exceeding the box of the door body 12 can be controlled within a very small range, meeting the requirements of embedded installation and facilitating the opening of the door body 12.

[0271] Exemplarily, during the process of the door body 12 being opened from the closed state to 90°, the maximum amount exceeding the box 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.

[0274] Since the first groove 1321 communicates with the second groove 1322, by setting the depth of the second groove 1322 to be greater than that of the first groove 1321 and making the length of the second shaft 1312 greater than the depth of the first groove 1321, the second shaft 1312 is prevented from entering the first groove 1321, ensuring the stability of the movement of the second shaft 1312 within the second groove 1322.

[0275] Please refer to ​ According to some embodiments of the present application, the spacing R between the main body 11 and the surrounding environmental components is 0 - 6 mm.

[0276] To improve the aesthetics, the spacing between the embedded refrigeration device 1 and the surrounding environmental components is generally small. By defining the spacing R between the main body 11 and the surrounding environmental components, while ensuring the aesthetics after installation, it is convenient for the installation and maintenance of the refrigeration device 1. Exemplarily, R can take values of 0, 1 mm, 2 mm, 3 mm, 4 mm, 4.5 mm, 6 mm or other values between 0 - 6 mm.

[0277] Please refer to ​ According to some embodiments of the present application, the thickness of the door body 12 can be 42 mm - 60 mm.

[0278] Since the hinge assembly 13 of the present application has a compact structure, the door body 12 can be adapted to be an ultra-thin door body 12, thereby reducing the space occupied by the door body 12 in the entire refrigeration device 1. The capacity of the entire refrigeration device 1 can be increased under the same volume, and the thickness of the entire refrigeration device 1 can be reduced under the same capacity.

[0279] Among them, the value range of the thickness S of the door body 12 is [42 mm, 60 mm]. Exemplarily, S can take values of 42 mm, 45 mm, 47 mm, 50 mm, 52 mm, 55 mm, 58 mm, 60 mm or other values between 42 mm - 60 mm, and no specific limitation is made here.
