DETAILED DESCRIPTION

[0060] Embodiments of the present application are described in detail below with reference to the accompanying drawings. Examples of the embodiments are shown in the 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 reference to the drawings are exemplary and are for the purpose of explaining the present application and should not be understood as limiting the present application.

[0061] With the development of society and the gradual improvement of living quality, people's demand for the installation aesthetics of household refrigeration equipment is increasingly prominent. Embedding the refrigeration equipment in the cabinet, i.e., forming an embedded refrigeration equipment to realize the homogenization of home decoration style has become popular.

[0062] However, in the related art, the refrigeration equipment installed in embedded mode generally uses a double-shaft double-slot hinge to ensure that the door body can be smoothly opened, but the double-shaft double-slot hinge structure is complex and occupies a large space.

[0063] Based on the above considerations, the present application proposes a refrigeration equipment, the layout of the hinge assembly is compact and occupies a small space, while realizing the smooth opening of the door body of the embedded refrigeration equipment, the thickness of the door body can be made thinner, and the capacity of the refrigeration equipment is improved.

[0064] Reference will now be made to Figures 1-20 The refrigeration equipment according to the embodiments of the present application is described.

[0065] Please refer to Figure 1 The refrigeration equipment 1 of the embodiments of the present application includes a main body 11, a door body 12, and a hinge assembly 13.

[0066] First of all, it should be pointed out that the refrigeration equipment 1 can be installed in an embedded mode in a surrounding environment piece, which can be a cabinet, a wall, or other adjacent appliances, etc., which is not specifically limited here, and in the subsequent writing and drawings, the cabinet body of the surrounding environment piece is taken as an example.

[0067] The main body 11 is provided with a containing space for containing and placing articles, and the front side of the main body 11 is provided with an opening communicating with the containing space. The door body 12 is installed on the opening side of the main body 11 to seal the containing space together with the main body 11, thereby providing a stable containing space for the articles.

[0068] Please refer to Figures 2-4 The door body 12 includes a front wall 121 and a side wall 122 arranged at an angle. The front wall 121 of the door body 12 is located on the front side of the door body 12, and the side wall 122 of the door body 12 is located on the side of the door body 12 close to the peripheral environment member. The front wall 121 and the side wall 122 of the door body 12 are connected at an angle. It should be noted that the two sides of the door body 12 of the single-door refrigerator in the width direction can be close to the peripheral environment member. In this application, the side wall 122 specifically refers to the side wall 122 on the side of the door body 12 close to the hinge assembly 13.

[0069] The hinge assembly 13 includes a first hinge member 131 mounted on the main body 11 and a second hinge member 132 mounted on the door body 12. The first hinge member 131 and the second hinge member 132 are rotationally connected. By mounting 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 achieving the opening and closing of the door body 12.

[0070] 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 slot 1321 and a second slot 1322 in communication with each other. The first shaft 1311 is in sliding connection with the first slot 1321, and the second shaft 1312 is in sliding connection with the second slot 1322.

[0071] The first hinge member 131 can include a mounting seat fixedly mounted on the main body 11. The first shaft 1311 and the second shaft 1312 are arranged 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 slot 1321 and a second slot 1322 in communication with each other. The first slot 1321 and the second slot 1322 in communication with each other can reduce the distance between the first slot 1321 and the second slot 1322, thereby reducing the space occupied by the second hinge member 132. Moreover, the minimum distance between the first shaft 1311 and the second slot 1322 and the minimum distance between the second shaft 1312 and the first slot 1321 can be smaller, thereby making the arrangement of the entire hinge assembly 13 more compact and facilitating the reduction of the space occupied by the entire hinge assembly 13.

[0072] During the opening or closing of the door body 12, the first shaft 1311 slides in the first slot 1321, and the second shaft 1312 slides in the second slot 1322, so as to constrain the trajectory of the movement 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 the peripheral environment member during the movement.

[0073] The distance between the first shaft 1311 and the front wall 121 is a first front distance, and the distance between the first shaft 1311 and the side wall 122 is a first side distance; the distance between the second shaft 1312 and the front wall 121 is a second front distance, and the distance between the second shaft 1312 and the side wall 122 is a second side distance.

[0074] In the process that the door body 12 is opened from the closed state to the maximum angle, the first shaft 1311 slides in the first slot 1321, and the second shaft 1312 slides in the second slot 1322; in the case that the door body 12 is in the closed state, the first front distance is greater than the second front distance, and the first side distance is less than the second side distance; in the case that the door body 12 is in the maximum angle, the first front distance is less than the second front distance, and the first side distance is greater than or equal to the second side distance, so that the door body 12 can be quickly opened in the case that the movement range of the two shafts is relatively small.

[0075] In the process that the door body 12 is opened from 90° to the maximum angle, the first front distance is less than the second front distance, and the first side distance changes from being less than the second side distance to being greater than or equal to the second side distance, so as to facilitate the large-angle opening of the door body 12.

[0076] According to the refrigeration equipment 1 provided in the application, the first slot 1321 and the second slot 1322 are arranged to be in communication with each other, so as to shorten the distance between the first slot 1321 and the second slot 1322, reduce the space volume occupied by the first slot 1321 and the second slot 1322, and limit the change relationship between the first front distance and the second front distance and the first side distance and the second side distance in the opening process of the door body 12, so that the space occupied by the hinge assembly 13 in the rotating process can be reduced, the ultra-thin door is facilitated to be adapted, interference with the surrounding environment is not prone to occur, the door body 12 of the embedded refrigeration equipment 1 can be opened at a large angle, and the user is facilitated to use.

[0077] According to some embodiments of the application, in the case that the relative angle between the door body 12 and the main body 11 is a fourth angle, the first front distance is equal to the second front distance, and the first side distance is less than the second side distance; in the case that the relative angle between the door body 12 and the main body 11 is a fifth angle, the first side distance is equal to the second side distance, and the first front distance is less than the second front distance; wherein the fourth angle is less than the fifth angle.

[0078] In the process that the door body 12 is opened from the closed state to the maximum angle, the fourth angle and the fifth angle are sequentially passed through.

[0079] In the case that the door body 12 is at the fourth angle, the first front distance is equal to the second front distance, that is, the first front distance is greater than the second front distance when the opening degree of the door body 12 is less than the fourth angle, and the first front distance is less than the second front distance when the opening degree of the door body 12 is greater than the fourth angle.

[0080] When the opening degree 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 degree 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 degree of the door body 12 is greater than the fifth angle, the first side distance is less than the second side distance.

[0081] The fourth angle can be 15°-45°, and exemplarily, the fourth angle can be 15°, 20°, 25°, 29.6°, 35°, 40°, 45° or other angles between 15°-45°, which is not specifically limited here.

[0082] The fifth angle can be 105°-125°, and exemplarily, the fifth angle can be 105°, 110°, 115°, 119.6°, 124° or other angles between 105°-125°, which is not specifically limited here.

[0083] Please refer to Figure 5 and Figure 6 , wherein, in the case that 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 10mm-20mm, the distance B0 between the axis center of the first shaft 1311 and the side wall 122 is 17mm-27mm, the distance C0 between the axis center of the second shaft 1312 and the front wall 121 is 6mm-16mm, and the distance D0 between the axis center of the second shaft 1312 and the side wall 122 is 30mm-40mm.

[0084] By limiting the arrangement position 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, and the structure of the hinge assembly 13 is compact, and the distance between the hinge assembly 13 and the front wall 121 and the side wall 122 is also small, so that the cooperation size of the hinge assembly 13 and the door body 12 is more compact, and the thickness of the door body 12 is reduced.

[0085] 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 from the axis center of the first shaft 1311 to the front wall 121, and the value range of A0 is [10mm, 20mm], and exemplarily, A0 can be 10mm, 12mm, 14mm, 16mm, 18mm, 19mm, 19.5mm, 20mm or other values between 10mm-20mm, which is not specifically limited here.

For example, C0 can be 6mm, 8mm, 10mm, 11.7mm, 12mm, 14mm, 16mm or other values between 6mm and 16mm.

[0088] The distance D0 between the axis of the second shaft 1312 and the side wall 122 refers to the length of the perpendicular line from the axis of the second shaft 1312 to the side wall 122, and D0 is in the range of [30mm, 40mm]. For example, D0 can be 30mm, 32mm, 34mm, 34.5mm, 36mm, 38mm, 40mm or other values between 30mm and 40mm.

[0089] According to the refrigeration equipment 1 provided by the embodiment of the present application, the first groove 1321 and the second groove 1322 are arranged in communication with each other, so as to shorten the distance between the first groove 1321 and the second groove 1322, reduce the space volume occupied by the first groove 1321 and the second groove 1322, and in the case that the door body 12 is in the closed state, the distance between the first shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 is 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 compact, so that the thickness of the door body 12 can be thinner under the premise of ensuring the rotation angle of the door body 12, and the ultra-thin door requirement of the refrigeration equipment 1 is met.

[0090] Please refer to Figure 7 According to some embodiments of the present application, in the case that the door body 12 is in the closed state, the angle α0 between the line connecting 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°.

[0091] By limiting the angle between the line connecting the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 of the door body 12, the motion track of the door body 12 when starting to rotate from the closed state can be controlled, and interference between the door body 12 and the surrounding environment when opening can be avoided.

[0094] 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, the layout of the first shaft 1311 and the second shaft 1312 is compact, and the occupied space is reduced.

[0095] 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 in the range of [0, 10mm], and exemplarily, W0 can be 0, 1mm, 2mm, 4mm, 6mm, 7.8mm, 8mm, 10mm or other values between 0 and 10mm, which is not limited herein.

[0096] 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 in the range of [5mm, 15mm], and exemplarily, M0 can be 5mm, 7mm, 9mm, 11mm, 13mm, 13.7mm, 15mm or other values between 5mm and 15mm, which is not limited herein.

[0097] Referring to Figure 7 According to some embodiments of the present application, in the case that the door body 12 is opened from the closed state, the angle β0 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the front wall 121 is 20°-40°, the angle γ0 between the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 and the front wall 121 is 40°-60°, and the angle θ0 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 is 20°-40° in the case that the door body 12 is opened from the closed state.

[0098] By limiting the angles β0 and γ0 between the tangents of the moving directions of the first shaft 1311 and the second shaft 1312 relative to the door body 12 and the front wall 121, and the 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 when the door body 12 is opened from the closed state, the moving track of the door body 12 when being opened can be constrained, and interference between the door body 12 and the surrounding environment can be avoided.

[0099] The value range of β0 is [20°, 40°], and β0 may, for example, take a value of 20°, 22°, 25°, 28.7°, 30°, 32°, 35°, 40°, or another value between 20° and 40°, which is not specifically limited herein.

[0100] The value range of γ0 is [40°, 60°], and γ0 may, for example, take a value of 40°, 42°, 45°, 50°, 52.8°, 55°, 57°, 60°, or another value between 40° and 60°, which is not specifically limited herein.

[0101] The value range of θ0 is [20°, 40°], and θ0 may, for example, take a value of 20°, 22°, 25°, 28.7°, 30°, 32°, 35°, 40°, or another value between 20° and 40°, which is not specifically limited herein.

[0102] According to some embodiments of the present application, when the door body 12 is in the 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.

[0103] By spacing at least one of the first shaft 1311 and the second shaft 1312 from the end of the corresponding first slot 1321 and second slot 1322, a certain negative door closing angle can be achieved when the door body 12 is in the closed state, thereby ensuring the sealing performance of the door body 12 when being closed.

[0104] Referring to Figure 6 and Figure 7 According to some embodiments of the present application, the first end of the first slot 1321 is in communication with the second slot 1322, and the first end of the second slot 1322 is spaced apart from the first end of the first slot 1321. When the door body 12 is in the closed state, the first shaft 1311 is located at the first end of the first slot 1321, and the second shaft 1312 is located at the first end of the second slot 1322.

[0105] It should be noted that the first end of the first slot 1321 and the first end of the second slot 1322 are starting ends, and when the door body 12 is in the closed state, the first shaft 1311 is located at the first end of the first slot 1321, the second shaft 1312 is located at the first end of the second slot 1322, and the first end of the first slot 1321 is in communication with the middle part of the second slot 1322, so that the starting position of the first shaft 1311 can be closer to the second slot 1322, and the overall structural layout is more compact, and the space occupied by the entire hinge assembly 13 is optimized.

[0106] 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 slot 1321 and the first end of the second slot 1322 is less than the distance between the axis of the first shaft 1311 and the axis of the second shaft 1312.

[0107] By setting the distance between the axes of the first shaft 1311 and the second shaft 1312 to be greater than the distance between the first end of the first slot 1321 and the first end of the second slot 1322, when the first shaft 1311 and the second shaft 1312 are located at the starting position, they are respectively located in the first slot 1321 and the second slot 1322, and the first shaft 1311 will not enter the second slot 1322 when the door body 12 is closed, thereby improving the stability of the hinge assembly 13 in operation.

[0108] Please refer to Figure 4 , Figure 8 and Figure 9 According to some embodiments of the present application, the side wall 122 and the front wall 121 intersect at the first edge 123, and when the first edge 123 is located at the first position, the distance A1 between the axis of the first shaft 1311 and the front wall 121 is 13-23mm, the distance B1 between the axis of the first shaft 1311 and the side wall 122 is 9-19mm, the distance C1 between the axis of the second shaft 1312 and the front wall 121 is 19-29mm, and the distance D1 between the axis of the second shaft 1312 and the side wall 122 is 22-32mm. The first position represents the position where the distance between the first edge and the surrounding environment is the smallest.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] The distance C1 between the axis of the second shaft 1312 and the front wall 121 refers to the length of the perpendicular line from the axis of the second shaft 1312 to the front wall 121, and C1 can be in the range of [19mm, 29mm], and can be 19mm, 21mm, 23mm, 25mm, 27mm, 28.3mm, 29mm or other values in the range of 19mm-29mm, which is not limited herein.

[0115] The distance D1 between the axis of the second shaft 1312 and the side wall 122 refers to the length of the perpendicular line from the axis of the second shaft 1312 to the side wall 122, and D1 can be in the range of [22mm, 32mm], and can be 22mm, 23.6mm, 26mm, 28mm, 30mm, 31mm, 32mm or other values in the range of 22mm-32mm, which is not limited herein.

[0116] According to the refrigeration equipment 1 provided by the embodiments of the present application, the first groove 1321 and the second groove 1322 are arranged to be in communication with each other, so as to shorten the distance between the first groove 1321 and the second groove 1322, reduce the space volume occupied by the first groove 1321 and the second groove 1322, and in the case that the first edge 123 is located at the first position, the overhang 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, the second shaft 1312, the first groove 1321 and the second groove 1322 is compact, so that the thickness of the door body 12 can be thinner under the premise of ensuring the rotation angle of the door body 12, and the ultra-thin door requirement of the refrigeration equipment 1 is met.

[0117] In some embodiments, in the case that the first edge 123 is located at the first position, the relative angle between the door body 12 and the main body 11 is 25°-80°, and in the case that the first edge 123 is located at the first position, the relative angle between the door body 12 and the main body 11 can be 65.9°.

[0118] Please refer to Figure 8 According to some embodiments of the present application, in the case that 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 can be less than or equal to 3mm.

[0119] It can be understood that the side surface 111 of the main body 11 is a surface of the main body 11 close to the peripheral environment, and when the door body 12 is in a 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, the first edge 123 will protrude outward beyond the side surface 111 of the main body 11, thereby there is a risk of interference with the peripheral 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.

[0120] When the first edge 123 is in the first position, the distance between the first edge 123 and the peripheral environment is the smallest, that is, when the first edge 123 is located at the position farthest from the side surface 111 of the main body 11. In order to avoid the first edge 123 from contacting the peripheral environment, it is limited 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. Therefore, the distance between the refrigeration equipment 1 and the peripheral environment is maximized to only 3 mm, and the door body 12 can be smoothly opened, thereby meeting the embedded installation requirement.

[0121] In some embodiments, when the first edge 123 is in the first position, the first edge 123 can be located inside the side surface 111 of the main body 11, so that the door body 12 does not protrude beyond 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 identified as a negative value. At this time, 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], and L1 can be -3mm, -2.5mm, -2mm, -1.5mm, -1mm, -0.5mm or other values between -3mm and 0mm.

[0122] In some embodiments, when the first edge 123 is in the first position, the first edge 123 can be located inside the side surface 111 of the main body 11, so that the door body 12 does not protrude beyond 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 identified as a negative value. At this time, 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], and L1 can be -3mm, -2.5mm, -2mm, -1.5mm, -1mm, -0.5mm or other values between -3mm and 0mm.

[0123] 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 peripheral environment is greater than or equal to 1mm.

[0124] The distance between the first edge 123 and the surrounding environment is limited to prevent interference with the surrounding environment when the first edge 123 extends the farthest from the side surface 111 of the main body 11. The distance L2 between the first edge 123 and the surrounding environment can be 1 mm, 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, or other values greater than 1 mm.

[0125] Referring to Figure 10 According to some embodiments of the present application, when the first edge 123 is in the first position, the angle a1 between the line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 is -51° to -21°.

[0126] During the opening of the door body 12 from the closed state, the angle between the 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 first edge 123 is in the first position, the line connecting the centers of the first axis 1311 and the second axis 1312 is parallel to the front wall 121.

[0127] It should be noted that for the sake of distinction, when the first axis 1311 is on the side of the second axis 1312 away from the front wall 121, the angle between the line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 is positive, and when the first axis 1311 is on the side of the second axis 1312 close to the front wall 121, the angle between the line connecting the centers of the first axis 1311 and the second axis 1312 and the front wall 121 is negative.

[0128] When the first edge 123 is in the first position, the angle a1 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 [-51°, -21°]. For example, a1 can be -51°, -45°, -40°, -36.3°, -30°, -25°, -21°, or other angles between -51° and -21°, which are not limited here.

[0129] Referring 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 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 center of the first axis 1311 and the first edge 123 is E1, which can satisfy:

[0130] E1-B0≤3.1mm.

[0131] 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 peripheral environment, and when the door body 12 is rotated to the first position where the first edge 123 is located, the first edge 123 is most likely to interfere with the peripheral environment, and by limiting E1-B0≤3.1mm, the size of the first edge 123 exceeding the side surface 111 of the main body 11 is controlled, so that the refrigeration equipment 1 can be better embedded for use.

[0132] E1-B0 can be 1.1mm, 1.6mm, 2.1mm, 2.6mm, 3.1mm or other values less than 3.1mm.

[0133] In another example, when the first edge 123 is located at the first position, the first edge 123 can not exceed the side surface 111 of the main body 11, that is, the over-box amount of the door body 12 during rotation is 0, and 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 negative.

[0134] Please refer to Figure 9 According to some embodiments of the present application, when the first edge 123 is located at 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 5mm-15mm, 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 5mm-15mm.

[0135] By limiting 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 constrained, so that the layout of the first shaft 1311 and the second shaft 1312 is compact, and the occupied space is reduced.

[0136] 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 [5mm, 15mm], and exemplarily, W1 can be 5mm, 7mm, 7.8mm, 9mm, 10mm, 12mm, 15mm or other values between 5mm and 15mm, which is not limited here.

[0137] The interval M1 of the shaft center of the first shaft 1311 and the shaft center of the second shaft 1312 in the width direction of the door body 12 is in the range of [5mm, 15mm], and exemplarily, M1 can be 5mm, 7mm, 9mm, 10mm, 12mm, 13.7mm, 15mm or other values between 5mm and 15mm, which is not limited here.

[0138] Please refer to 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 moving direction of the first shaft 1311 relative to the first slot 1321 and the front wall 121 is -25° to -45°, the angle γ1 between the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 and the front wall 121 is 50° to 70°, and the angle θ1 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 is 75° to 115°.

[0139] It should be noted here that, for the sake of distinction, when the moving direction of the first shaft 1311 and the second shaft 1312 is away from the front wall 121, the angle between the tangent of the moving direction of the shaft relative to the slot and the front wall 121 is positive,

[0140] By limiting the angle between the tangent of the moving direction of the first shaft 1311 and the second shaft 1312 relative to the door body 12 and the front wall 121 and the angle between the tangent of the moving direction of the first shaft 1311 and the second shaft 1312 relative to the door body 12 when the first edge 123 moves to the first position, the moving direction of the first edge 123 is away from the peripheral environmental member when the door body 12 continues to rotate, which avoids interference caused by the first edge 123 being too close to the peripheral environmental member.

[0141] The value range of β1 is [-25°, -45°], and exemplarily, β1 can be -25°, -30°, -35°, -38.8°, -40°, -45° or other angles between -25° and -45°, which is not limited here.

[0142] The value range of γ1 is [50°, 70°], and exemplarily, γ1 can be 50°, 55°, 60°, 63.2°, 65°, 70° or other angles between 50° and 70°, which is not limited here.

[0143] The value range of θ1 is [75°, 115°], and exemplarily, θ1 can be 75°, 80°, 90°, 102°, 110°, 115° or other angles between 75° and 115°, which is not limited here.

[0144] 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 of the first shaft 1311 and the front wall 121 is 12mm-22mm, the distance B2 between the axis of the first shaft 1311 and the side wall 122 is 9mm-19mm, the distance C2 between the axis of the second shaft 1312 and the front wall 121 is 28mm-38mm, and the distance D2 between the axis of the second shaft 1312 and the side wall 122 is 17mm-27mm.

[0145] 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 shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 at this position, the relative position of the door body 12 is controlled to be not too large when the door body 12 is opened to 90°, and the intrusion amount is not too large in the case that the distance between the embeddedly installed refrigeration equipment 1 and the surrounding environment is small, which is convenient for the user to use when the door body 12 is normally opened.

[0146] In addition, 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, and the distance between the hinge assembly 13 and the front wall 121 and the side wall 122 is also small, so that the cooperation size of the hinge assembly 13 and the door body 12 is more compact, which is convenient for reducing the thickness of the door body 12.

[0147] The distance A2 between the axis of the first shaft 1311 and the front wall 121 refers to the length of the perpendicular line from the axis of the first shaft 1311 to the front wall 121, and the value range of A2 is [12mm, 22mm]. For example, A2 can take the value of 12mm, 14mm, 16mm, 18mm, 19.5mm, 20mm, 22mm or other values between 12mm and 22mm, which is not specifically limited here.

[0148] The distance B2 between the axis of the first shaft 1311 and the side wall 122 refers to the length of the perpendicular line from the axis of the first shaft 1311 to the side wall 122, and the value range of B2 is [9mm, 19mm]. For example, B2 can take the value of 9mm, 11mm, 11.2mm, 13mm, 15mm, 17mm, 19mm or other values between 9mm and 19mm, which is not specifically limited here.

[0149] The distance C2 between the axis of the second shaft 1312 and the front wall 121 refers to the length of the perpendicular line from the axis of the second shaft 1312 to the front wall 121, and C2 is in the range of [28mm, 38mm], and for example, C2 can be 28mm, 30mm, 32mm, 34mm, 34.5mm, 36mm, 38mm or other values between 28mm and 38mm, which are not limited herein.

[0150] The distance D2 between the axis of the second shaft 1312 and the side wall 122 refers to the length of the perpendicular line from the axis of the second shaft 1312 to the side wall 122, and D2 is in the range of [17mm, 27mm], and for example, D2 can be 17mm, 20mm, 21mm, 22mm, 23mm, 25mm, 27mm or other values between 17mm and 27mm, which are not limited herein.

[0151] According to the refrigeration equipment 1 provided by the embodiments of the present application, the first groove 1321 and the second groove 1322 are arranged to be in communication with each other, so as to shorten the distance between the first groove 1321 and the second groove 1322, reduce the space volume occupied by the first groove 1321 and the second groove 1322, and in the case that the relative angle between the door body 12 and the main body 11 is 90°, the distance between the first shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 is 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, so that the thickness of the door body 12 can be made thinner under the premise of ensuring the rotation angle of the door body 12, and the ultra-thin door requirement of the refrigeration equipment 1 is met.

[0152] Please refer to Figure 11 According to some embodiments of the present application, in the case that 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 63mm.

[0153] The intrusion amount of the door body 12 refers to the intrusion amount of the door body 12 to the center of the main body 11 relative to the side surface 111 of the main body 11 after the door body 12 is opened, and the smaller the intrusion amount is, the more convenient the use is, for example, when a drawer is arranged in the refrigeration equipment 1, there is a use scenario of pulling the drawer, and the smaller the intrusion amount of the door body 12 is, the smaller the interference probability between the drawer and the door body 12 is, and at the same time, the drawer can be made wider to improve the accommodation space.

[0154] The door body 12 can include a rear wall 124 opposite to the front wall 121, and the door seal 14 is arranged on the rear wall 124. In the case that 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, and plays a sealing and heat insulation role. In the case that 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 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 face of the door seal 14 away from the door body 12 and the side surface 111 of the main body 11.

[0155] In the related art, in order to make the door body avoid the peripheral environmental member, the horizontal moving distance of the door body generally causes a large intrusion amount, which greatly affects the internal design of the refrigeration equipment. For example, the width of the drawer needs to be reduced to facilitate the pulling use of the drawer. The application controls the intrusion amount of the door body 12 in a smaller range by limiting the intrusion amount of the door body 12 to be less than or equal to 63 mm, thereby improving the user experience.

[0156] Exemplarily, the intrusion amount H1 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.

[0157] In an 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, so that the intrusion amount is small and the user experience is better.

[0158] Please refer to Figure 11 According to some embodiments of the application, in the case that the relative angle between the door body 12 and the main body 11 is 90°, the inward moving amount of the door body 12 is less than or equal to 3 mm.

[0159] In the case that 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. Because the peripheral environmental member needs to be avoided during the opening of the door body 12, the door body 12 as a whole moves towards the center of the main body 11. When the door body 12 is located 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, and the distance F between the front wall 121 and the side surface 111 of the main body 11 is the inward moving amount of the door body 12. By limiting the inward moving amount, the occupation of the using space by the door body 12 is reduced, the drawer can be made larger, and the aesthetic appearance is higher.

[0160] F can be 3 mm, 2.5 mm, 2 mm, 1.5 mm, 1 mm, 0.5 mm or other values less than 3 mm, which is not limited here.

[0161] Please refer to Figure 6 and Figure 12According to some embodiments of the present application, when the door body 12 is in the closed state, the distance A0 between the axis of the first shaft 1311 and the front wall 121, and the distance B2 between the first shaft 1311 and the side wall 122 when the relative angle between the door body 12 and the main body 11 is 90°, can satisfy:

[0162] -3mm≤B2-A0≤3mm.

[0163] 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, so the distance between the axis of the first shaft 1311 and the side wall 122 at this time is the distance between the axis 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°, the side wall 122 is rotated to be perpendicular to the side surface 111 of the main body 11 at this time, and the front wall 121 is parallel to the main body 11, because the first shaft 1311 is relatively fixed with 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 that the door body 12 is opened to 90° can be calculated through the distance between the axis 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 determined.

[0164] By limiting -3mm≤B2-A0≤3mm, the intrusion amount of the door body 12 is controlled in a very small range, thereby improving the use experience of the refrigeration equipment 1.

[0165] Wherein, B2-A0 can take values of -3mm, -2mm, -1mm, 0mm, 1mm, 2mm, 3mm or other values between -3mm and 3mm, which are not specifically limited here.

[0166] 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 angle between the line connecting 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°.

[0167] During the opening process of the door body 12 from the closed state, the angle between the line connecting the axes of the first shaft 1311 and the second shaft 1312 and the front wall 121 first decreases and then increases, and before the door body 12 is opened to a relative angle of 90° with the main body 11, there is a state that the line connecting the axes of the first shaft 1311 and the second shaft 1312 is parallel to the front wall 121.

[0168] When the relative angle between the door body 12 and the main body 11 is 90°, the angle a2 between the line connecting the axis centers of the first shaft 1311 and the second shaft 1312 and the front wall 121 is in the range of [-75°, -45°], and a2 may, for example, be -75°, -70°, -65°, -60.4°, -55°, -50°, -45°, or another angle in the range of -75° to -45°, which is not limited herein.

[0169] Referring 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 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 5mm-15mm, and the interval M2 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 5mm-15mm.

[0170] By limiting the interval W2 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 M2 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, the layout of the first shaft 1311 and the second shaft 1312 is compact, and the occupied space is reduced.

[0171] 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 in the range of [5mm, 15mm], and W2 may, for example, be 5mm, 7mm, 9mm, 11mm, 13mm, 13.7mm, 15mm, or a value in the range of 5mm-15mm, which is not limited herein.

[0172] 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 in the range of [5mm, 15mm], and M2 may, for example, be 5mm, 7mm, 7.8mm, 9mm, 11mm, 13mm, 15mm, or a value in the range of 5mm-15mm, which is not limited herein.

[0173] Referring to Figure 13According to some embodiments of the present application, in the case that the door body 12 is opened to 90°, the angle β2 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the front wall 121 is -25° to -45°, the angle γ2 between the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 and the front wall 121 is 5° to 25°, and the angle θ2 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 is 30° to 70°.

[0174] By limiting the angle β2 and γ2 between the tangent of the moving direction of the first shaft 1311 and the second shaft 1312 relative to the door body 12 and the front wall 121, and the angle θ2 between the tangent of the moving direction of the first shaft 1311 and the second shaft 1312 relative to the door body 12 in the case that the door body 12 is opened to 90°, the posture of the door body 12 when it continues to rotate is constrained, direct interference between the door body 12 and the surrounding environment is avoided, and the door body 12 can be opened to a larger angle.

[0175] The value range of β2 is [-25°, -45°], and β2 can exemplarily take a value of -25°, -30°, -34.9°, -40°, -45° or other angles between -25° and -45°, which is not specifically limited herein.

[0176] The value range of γ2 is [5°, 25°], and γ2 can exemplarily take a value of 5°, 10°, 15°, 17.1°, 20°, 25° or other angles between 5° and 25°, which is not specifically limited herein.

[0177] The value range of θ2 is [30°, 70°], and θ2 can exemplarily take a value of 30°, 35°, 40°, 45°, 50°, 52°, 60°, 70° or other angles between 30° and 70°, which is not specifically limited herein.

[0178] Please refer to Figure 14 and Figure 15 According to some embodiments of the present application, in the case that 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 7mm-17mm, the distance B3 between the axis of the first shaft 1311 and the side wall 122 is 4.5mm-14.5mm, the distance C3 between the axis of the second shaft 1312 and the front wall 121 is 21mm-31mm, and the distance D3 between the axis of the second shaft 1312 and the side wall 122 is 4mm-14mm.

[0179] It can be understood that the maximum relative angle of the door body 12 and the main body 11 is that the door body 12 is opened to the maximum angle, and the maximum relative angle of 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, the door body 12 can continue to be opened to the maximum angle to facilitate the user to use. By limiting the distance between the first shaft 1311 and the second shaft 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. In the case that the distance between the embedded refrigeration equipment 1 and the surrounding environment is small, it is ensured that the maximum angle is sufficient for the user to use.

[0180] In addition, in the case that the relative angle of the door body 12 and the main body 11 is maximum, the distance from the first shaft 1311 and the second shaft 1312 to the front wall 121 and the side wall 122 is small. While the structure of the hinge assembly 13 is compact, the distance between the hinge assembly 13 and the front wall 121 and the side wall 122 is also small. The cooperation size of the hinge assembly 13 and the door body 12 is more compact, which is convenient for reducing the thickness of the door body 12.

[0181] The distance A3 between the axis of the first shaft 1311 and the front wall 121 refers to the length of the perpendicular line from the axis of the first shaft 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 and 17mm, which is not specifically limited here.

[0182] The distance B3 between the axis of the first shaft 1311 and the side wall 122 refers to the length of the perpendicular line from the axis of the first shaft 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 and 14.5mm, which is not specifically limited here.

[0183] The distance C3 between the axis of the second shaft 1312 and the front wall 121 refers to the length of the perpendicular line from the axis of the second shaft 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 and 31mm, which is not specifically limited here.

[0184] The distance D3 between the axis of the second shaft 1312 and the side wall 122 refers to the length of the perpendicular line from the axis of the second shaft 1312 to the side wall 122, and D3 is in the range of [4mm, 14mm], and for example, D3 can be 4mm, 6mm, 8mm, 9.6mm, 10mm, 12mm, 14mm or other values between 4mm and 14mm, which are not limited herein.

[0185] According to the refrigeration equipment 1 provided by the embodiments of the present application, the first groove 1321 and the second groove 1322 are arranged to be in communication with each other, so as to shorten the distance between the first groove 1321 and the second groove 1322, reduce the space volume occupied by the first groove 1321 and the second groove 1322, and in the case that 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 shaft 1311 and the second shaft 1312 and the front wall 121 and the side wall 122 is still small, that is, the arrangement of the first shaft 1311, the second shaft 1312, the first groove 1321 and the second groove 1322 is relatively compact, so that the thickness of the door body 12 can be thinner under the premise of ensuring the rotation angle of the door body 12, and the ultra-thin door requirement of the refrigeration equipment 1 is met.

[0186] Please refer to Figure 11 and Figure 14 According to some embodiments of the present application, in the case that 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 in the case that 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:

[0187] H1 < H2.

[0188] It can be understood that the door body 12 further includes a rear wall 124 opposite to the front wall 121, and the rear wall 124 intersects with the side wall 122 at the 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 in the case that 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 door body 12 closest to the opening center of the main body 11, that is, the distance between the second edge 125 and the side surface 111 of the main body 11 at this time is the intrusion amount of the door body 12.

[0189] It can be understood that when a general user uses the refrigeration equipment 1, the most used state is to open the door body 12 to 90°, and therefore the internal design of the refrigeration equipment 1 ensures that the door body 12 can normally take and place articles in the state of being opened to 90°, for example, when a drawer is arranged in the refrigeration equipment 1, the door body 12 does not affect the pulling use of the drawer, and the purpose of being further opened after being opened to 90° is to provide better use experience, and by limiting the intrusion amount L1 < L2, the normal use of the refrigeration equipment 1 is not affected, for example, the normal pulling use of the drawer is not affected, in the case that the relative angle of the door body 12 and the main body 11 is maximum.

[0190] Referring to Figure 14 According to some embodiments of the present application, in the case that the relative angle of the door body 12 and the main body 11 is maximum, the intrusion amount H2 of the door body 12 is less than or equal to 63 mm.

[0191] In the related art, in order to make the door body avoid the peripheral environmental member, the intrusion amount is generally large, which greatly affects the internal design of the refrigeration equipment, for example, the width of the drawer needs to be reduced so as to facilitate the pulling use of the drawer, and the present application limits the intrusion amount of the door body 12 in the case that the relative angle of the door body 12 and the main body 11 is maximum, so as to control the intrusion amount of the door body 12 in a very small range, which has little effect on the use of the refrigeration equipment 1 and improves the use experience.

[0192] Exemplarily, 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 is not limited here.

[0193] Referring to Figure 11 According to some embodiments of the present application, in the case that the relative angle of the door body 12 and the main body 11 is maximum, the inward movement amount of the door body 12 is less than or equal to 3 mm.

[0194] In the case that the relative angle of the door body 12 and the main body 11 is maximum, the front wall 121 is parallel to the side surface 111 of the main body 11, because the door body 12 as a whole needs to move towards the center of the main body 11 to avoid the peripheral environmental member during the opening process of the door body 12, so that the second edge 125 is located on the side closest to the center of the main body 11 when the door body 12 is opened to the maximum angle. The distance between the second edge 125 and the side surface 111 of the main body 11 minus the thickness of the door body is the inward movement amount of the door body 12 when the door body 12 is opened to the maximum angle. By limiting the inward movement amount, the intrusion of the door body 12 to the use space is reduced, the drawer can be larger, and the aesthetic appearance is higher.

[0195] The inner displacement of the door body 12 when opened to the maximum angle can be 3mm, 2.5mm, 2mm, 1.5mm, 1mm, 0.5mm or other values less than 3mm, which is not limited here.

[0196] Please refer to Figure 16 According to some embodiments of the present application, the angle a3 between the line connecting the centers of the first shaft 1311 and the second shaft 1312 and the front wall 121 is -105° to -75° when the relative angle between the door body 12 and the main body 11 is the largest.

[0197] During the process of opening the door body 12 from 90° to the maximum angle, the angle between the line connecting the centers of the first shaft 1311 and the second shaft 1312 and the front wall 121 gradually increases, and when the door body 12 is opened to the maximum angle, the angle a3 between the line connecting the centers of the first shaft 1311 and the second shaft 1312 and the front wall 121 is in the range of [-105°, -75°], and exemplarily, a3 can be -105°, -100°, -95°, -90.4°, -85°, -80°, -75° or other angles between -105° and -75°, which is not limited here.

[0198] Please refer to Figure 15 According to some embodiments of the present application, the distance between the center of the first shaft 1311 and the center of the second shaft 1312 in the thickness direction of the door body 12 is 10mm-25mm, and the distance between the center of the first shaft 1311 and the center of the second shaft 1312 in the width direction of the door body 12 is 0-5mm when the relative angle between the door body 12 and the main body 11 is the largest.

[0199] By limiting the distance between the center of the first shaft 1311 and the center of the second shaft 1312 in the thickness direction of the door body 12, and the distance between the center of the first shaft 1311 and the 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, and the layout of the first shaft 1311 and the second shaft 1312 is compact, reducing the occupied space.

[0200] The distance W3 between the center of the first shaft 1311 and the center of the second shaft 1312 in the thickness direction of the door body 12 is in the range of [10mm, 25mm], and exemplarily, W3 can be 10mm, 12mm, 14mm, 15.8mm, 18mm, 20mm, 22mm, 25mm or other values between 10mm and 25mm, which is not limited here.

[0201] The interval M3 of the axial center of the first shaft 1311 and the axial center of the second shaft 1312 in the width direction of the door body 12 is in the range of [0, 5mm], and exemplarily, M3 can be 0mm, 0.1mm, 0.2mm, 1mm, 2mm, 3mm, 4mm, 5mm or other values between 0-5mm, which is not specifically limited here.

[0202] Please refer to Figure 16 According to some embodiments of the present application, the relative angle between the door body 12 and the main body 11 is the largest, the angle β3 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the front wall 121 is -120° to -140°, the angle γ3 between the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 and the front wall 121 is -55° to -75°, and the angle θ3 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 is 50° to 70°.

[0203] By limiting the relative angle between the door body 12 and the main body 11 to the largest, the angle β3 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the front wall 121 and the angle γ3 between the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322 and the front wall 121, and the angle θ3 between the tangent of the moving direction of the first shaft 1311 relative to the first slot 1321 and the tangent of the moving direction of the second shaft 1312 relative to the second slot 1322, the stability of the door body 12 when rotating to the largest angle is constrained, and the intrusion amount of the door body 12 is controlled.

[0204] Wherein, the value range of β3 is [-120°, -140°], and exemplarily, β3 can be -120°, -125°, -129°, -133°, -135°, -140° or other angles between -120° and -140°, which is not specifically limited here.

[0205] The value range of γ3 is [-55°, -75°], and exemplarily, γ3 can be -55°, -60°, -65°, -67°, -70°, -75° or other angles between -55° and -75°, which is not specifically limited here.

[0206] The value range of θ3 is [50° to 70°], and exemplarily, θ3 can be 50°, 55°, 58°, 60°, 65°, 70° or other angles between 50° and 70°, which is not specifically limited here.

[0207] According to some embodiments of the present application, the relative angle between the door body 12 and the main body 11 can be the largest, which is 115°-125°.

[0208] Exemplarily, the 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 is not limited herein.

[0209] Please refer to Figure 17 , Figure 18 , Figure 19 and Figure 20 , according to some embodiments of the present application, during the process that the door body 12 is 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 moves away from and then approaches the front wall 121 to form the first trajectory a, the first shaft 1311 reciprocates away from and approaches the front wall 121 to form the second trajectory b, and the first shaft 1311 moves toward the front wall 121 to form the 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 the fourth trajectory d, and the second shaft 1312 moves toward the front wall 121 to form the fifth trajectory e.

[0210] Because the first shaft 1311 and the second shaft 1312 are fixed on 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. During the process that the door body 12 is opened from the closed state to the maximum angle, the total trajectory of the first shaft 1311 can be sequentially divided into the first trajectory a, the second trajectory b and the third trajectory c.

[0211] The first trajectory a includes two segments of extending away from the front wall 121 and then extending toward the front wall 121; the second trajectory b includes two segments of extending away from the front wall 121 and then extending toward the front wall 121, and because the first shaft 1311 reciprocates to form the second trajectory b, the two segments of the second trajectory b overlap with each other, and in the second trajectory b, the segment of 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 segment of retreat is formed in the overall movement direction; the third trajectory c extends toward the front wall 121.

[0212] It can be understood that the fourth trajectory d and the fifth trajectory e are staggered 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, wherein the fourth trajectory d extends in the direction away from the front wall 121, and the fifth trajectory e extends in the direction toward the front wall 121.

[0213] By limiting the movement trajectories of the first shaft 1311 and the second shaft 1312, in the initial stage of opening the door body 12 from the closed state to the maximum angle, the first shaft 1311 and the second shaft 1312 are both moved 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 intermediate stage of opening the door body 12 from the closed state to the maximum angle, the first shaft 1311 forms a retreat in the movement direction, which is set to effectively control the over-box amount of the door body 12 in the rotating process, and cooperates with the movement of the second shaft 1312 to quickly rotate and open the door body 12, reduces the space occupied by the first shaft 1311 in the rotating process of the door body 12, and thus facilitates the reduction of the space occupied by the entire hinge assembly 13; in the final stage of opening the door body 12 from the closed state to the maximum angle, the first shaft 1311 and the second shaft 1312 are both moved in the direction close to the front wall 121, to facilitate the large-angle opening of the door body 12.

[0214] And from the above, it can be seen that the total movement trajectories of the first shaft 1311 and the second shaft 1312 both have a turning point, further reducing the occupation of the space in the thickness direction of the door body 12 by the first shaft 1311 and the second shaft 1312 in the relative movement process with the door body 12, so that the thickness of the door body 12 can be thinner, not only the mass of the door body 12 can be lighter, but also the thickness distribution of the entire refrigeration equipment 1 is optimized, and the seniority and practicability of the refrigeration equipment 1 are improved.

[0215] According to the refrigeration equipment 1 of the embodiments of the present application, by limiting the movement trajectories of the first shaft 1311 and the second shaft 1312, not only the space occupied by the hinge assembly 13 in the rotating process can be reduced, facilitating the adaptation of the ultra-thin door, and interference with the surrounding environment is not easy to occur, the door body 12 of the refrigeration equipment 1 which can be embeddedly installed can be opened at a large angle, and the user is facilitated to use.

[0216] 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.

[0217] In the process that the first shaft 1311 moves along the first track a and the second track b, the second shaft 1312 moves along the fourth track d all the time, and in the process that the first shaft 1311 moves along the third track c, the second shaft 1312 moves along the fifth track e. In the process that the first shaft 1311 moves along the first track a, the first shaft 1311 has a turning point with the front wall 121, and in the process that the first shaft 1311 moves along the second track b, the first shaft 1311 has a retraction and a turning point, and in the process that the moving direction of the first shaft 1311 has two turning points relative to the front wall 121, the second shaft 1312 always moves along the fourth track d away from the front wall 121, and through the cooperation of the first shaft 1311 and the second shaft 1312, the first shaft 1311 and the second shaft 1312 can be quickly opened to a use opening degree in a limited movement space.

[0218] In the process that the second shaft 1312 moves along the fifth track e to approach the front wall 121, the first shaft 1311 moves along the third track c to approach the front wall 121, so as to increase the distance between the front wall 121 and the surrounding environment, and in the embedded installation of the refrigeration equipment 1, the front wall 121 of the door body 12 avoids the surrounding environment to realize a large-angle opening.

[0219] Please refer to Figure 17 According to some embodiments of the present application, in the process that the door body 12 is opened from the closed state to the first angle, the first shaft 1311 moves along the first track a, and the second shaft 1312 moves along the fourth track d.

[0220] The first shaft 1311 moves away from the front wall 121 first and then moves towards the front wall 121, and the second shaft 1312 moves away from the front wall 121 along the fourth track d. It can be seen that the first shaft 1311 first passes through a turning point in the direction in the movement process, and the first shaft 1311 and the second shaft 1312 first move away from the front wall 121 together, so that the door body 12 as a whole first moves away from the main body 11, which facilitates the subsequent opening process of the door body 12 and prevents the door body 12 from interfering with the main body 11. Then, the first shaft 1311 moves in the direction of approaching the front wall 121, so that the instantaneous rotation center of the door body 12 quickly approaches the door body 12, the rotation speed of the door body 12 is increased after the distance between the door body 12 and the main body 11 is sufficient, and the invasion amount of the door body 12 is reduced.

[0221] Figure 18 and Figure 19 In the process that the door body 12 is opened from the first angle to the second angle, the first shaft 1311 first retracts and then moves forward along the second track b, and the second shaft 1312 moves along the fourth track d.

[0222] It can be understood that the second angle is greater than the first angle. When the door body 12 is continuously opened from the first angle, the first shaft 1311 first retreats and then reciprocates forward along the second trajectory b, so that the first shaft 1311 first moves away from the front wall 121 and then moves close to the front wall 121. In this process, the second shaft 1312 continuously moves away from the front wall 121 along the fourth trajectory d. The retreat of the first shaft 1311 can control the over-box amount of the first side edge 123 during the rotation of the door body 12, and also enable the door body 12 to be quickly opened. Moreover, the retreat movement makes the occupied space of the movement track of the first shaft 1311 smaller, which corresponds to the first groove 1321 on the door body 12, so that the required size of the first groove 1321 is smaller, and the occupied space of the entire hinge assembly 13 is smaller.

[0223] Referring to Figure 20 In the process that 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.

[0224] When the door body 12 is continuously opened from the second angle, the first shaft 1311 moves close to the front wall 121 along the third trajectory c, and the second shaft 1312 also moves close to the front wall 121 along the fifth trajectory e. Correspondingly, the front wall 121 as a whole moves in the direction close 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 installation of the refrigeration equipment 1, the front wall 121 of the door body 12 can avoid the surrounding environmental components to achieve large-angle opening.

[0225] Referring to Figures 17-20 According to some embodiments of the present application, the first shaft 1311 moves close to the side wall 122 along the first trajectory a, moves away from the side wall 122 when the first shaft 1311 retreats along the second trajectory b, and then moves close to the side wall 122 after the retreat is completed. 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. The second shaft 1312 always moves close to the side wall 122 along the fourth trajectory d and the fifth trajectory e.

[0226] In the initial stage of the door body 12 being opened from the closed state to the maximum angle, the first shaft 1311 moves along the first trajectory a to approach the side wall 122, and the second shaft 1312 moves along the fourth trajectory d to approach the side wall 122, so that the door body 12 has a tendency to move to the side close to the center of the opening relative to the main body 11, thereby avoiding interference between the door body 12 and the surrounding environment close to the side wall 122 when the door body 12 is opened; in the middle stage of the door body 12 being opened from the closed state to the maximum angle, the first shaft 1311 moves along the second trajectory b to retreat, so that the first shaft 1311 moves away from the side wall 122, and the second shaft 1312 moves to approach the side wall 122, so as to control the overbox amount of the first edge 123 connected with the side wall 122 not to be too large, meet the embedded installation requirement, and make the door body 12 rotate quickly; in the late stage of the door body 12 being opened from the closed state to the maximum angle, the first shaft 1311 moves along the third trajectory c to first approach the side wall 122 and then move away from the side wall 122, so as to facilitate the large-angle opening of the door body 12, and control the space occupied by the movement trajectory of the first shaft 1311, so that the structure of the entire hinge assembly 13 is more compact, the large-angle opening can be realized for the ultra-thin door body 12, and the invasion amount of the main body 11 is small.

[0227] According to some embodiments of the present application, in the process of the door body 12 being opened from the closed state to the first angle, the virtual rotation center of the door body 12 and the side wall 122 are located on both sides of the axis center line of the first shaft 1311 and the second shaft 1312 respectively; in the process of the door body 12 being opened from the first angle to the third angle, the virtual rotation center of the door body 12 and the side wall 122 are located on the same side of the axis center line of the first shaft 1311 and the second shaft 1312; in the process of the door body 12 being opened from the third angle to the maximum angle, the virtual rotation center of the door body 12 and the side wall 122 are located on both sides of the axis center line of the first shaft 1311 and the second shaft 1312 respectively; wherein the third angle is the angle of the door body 12 when the first shaft 1311 retreats to the limit.

[0228] It can be understood that the third angle is greater than the first angle and less than the second angle.

[0229] According to some embodiments of the present application, in the case that the relative angle between the door body 12 and the main body 11 is 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 shaft 1311.

[0242] Please refer to Figures 17-20 According to some embodiments of the present application, during the process that the door body 12 is opened from the closed state to the maximum angle, the first shaft 1311 can slide relative to the first groove 1321 from the first starting position, so that the first shaft 1311 moves away from and then approaches the front wall 121 to form a first trajectory a, the first shaft 1311 reciprocates away from and approaches the front wall 121 to form a second trajectory b, and the first shaft 1311 moves toward the front wall 121 to form a third trajectory c; the second shaft 1312 can slide relative to the second groove 1322 from the second starting position, 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 toward the front wall 121 to form a fifth trajectory e.

[0243] It should be noted that, when the door body 12 is in the closed state, the first shaft 1311 is located at the first starting position in the first groove 1321, and the second shaft 1312 is located at the second starting position in the second groove 1322, when the door body 12 is opened from the closed state, the first shaft 1311 slides relative to the first groove 1321 from the first starting position to form the first trajectory a, the second trajectory b and the third trajectory c, and the second shaft 1312 slides relative to the second groove 1322 from the second starting position to form the fourth trajectory d and the fifth trajectory e, wherein the related features of the first trajectory a, the second trajectory b, the third trajectory c, the fourth trajectory d and the fifth trajectory e can refer to the foregoing embodiments, which will not be described here.

[0251] According to the refrigeration equipment 1 provided in the embodiments of the present application, by limiting the movement trajectories of the first shaft 1311 and the second shaft 1312, the space occupied by the hinge assembly 13 during rotation can be reduced, and interference with the surrounding environment is not easy to occur, so that the door body 12 of the embedded refrigeration equipment 1 can be opened at a large angle, which is convenient for users to use, and when the door body 12 is in a 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 small, that is, the first shaft 1311 and the second shaft 1312, the first groove 1321 and the second groove 1322 are arranged more compactly, so that the thickness of the door body 12 can be thinner under the premise of ensuring the rotation angle of the door body 12, thereby meeting the ultra-thin door requirement of the refrigeration equipment 1 and facilitating the adaptation of the ultra-thin door.

[0281] The value range of β3 is [-120°, -140°], and β3 may exemplarily take a value of -120°, -125°, -129°, -133°, -135°, -140°, or other angles between -120° and -140°, which is not specifically limited herein.

[0288] It can be understood that, when the relative angle between the door body 12 and the main body 11 reaches 90°, the normal use opening angle required to use the drawer is reached, by limiting the intrusion amount of the door body 12 during the process that the door body 12 is opened from 90° to the maximum angle to be less than or equal to 63mm, the intrusion amount of the door body 12 is controlled within a smaller range, while not interfering with the surrounding environment, the width of the drawer can be made wider, increasing the space of the drawer.

[0289] Exemplarily, the maximum intrusion of the door body 12 can be 63mm, 60mm, 59mm, 57mm, 56.5mm, 56.4mm or other values less than 63mm during the process that the door body 12 is opened by 90° to the maximum angle.

[0291] It can be understood that the normal use opening angle of the drawer is reached when the relative angle between the door body 12 and the main body 11 reaches 90°, and by limiting the inward movement of the door body 12 to be less than or equal to 3mm during the process that the door body 12 is opened by 90° to the maximum angle, the inward movement of the door body 12 is controlled within a smaller range, and at the same time without interfering with the surrounding environment, the width of the drawer can be wider, increasing the space of the drawer.

[0292] wherein F can be 3mm, 2.5mm, 2mm, 1.5mm, 1mm, 0.5mm or other values less than 3mm, which are not limited here.

[0294] It can be understood that the most commonly used opening use angle of the door body 12 is reached when the relative angle between the door body 12 and the main body 11 reaches 90°, and the embedded refrigeration equipment 1 needs to ensure that the door body 12 can be opened by at least 90° without interfering with the surrounding environment, and by limiting the overbox amount of the door body 12 to be less than or equal to 3mm during the process that the door body 12 is opened from the closed state to 90°, the overbox amount of the door body 12 is controlled within a very small range, meeting the needs of embedded installation and facilitating the opening of the door body 12.

[0295] Exemplarily, the maximum overbox amount of the door body 12 can be 0, 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm or other values less than 3mm during the process that the door body 12 is opened from the closed state to 90°.

[0296] In some embodiments, when the door body 12 is rotated to a relative angle of 25°-80° with the main body 11, the first edge 123 of the door body 12 will exceed the side surface 111 of the main body 11.

[0298] Because the first groove 1321 is in communication with the second groove 1322, by setting the depth of the second groove 1322 to be greater than the depth of the first groove 1321, and making the length of the second shaft 1312 greater than the depth of the first groove 1321, so that the second shaft 1312 does not enter the first groove 1321, the stability of the movement of the second shaft 1312 in the second groove 1322 is ensured.

[0299] Referring to Figure 5 According to some embodiments of the present application, the distance R between the main body 11 and the surrounding environment is 0-6mm.

[0300] In order to improve the aesthetic appearance, the distance between the embeddedly installed refrigeration equipment 1 and the surrounding environment is generally small, by limiting the distance R between the main body 11 and the surrounding environment, the installation and maintenance of the refrigeration equipment 1 is facilitated while the aesthetic appearance after installation is ensured. Exemplarily, R can take values of 0, 1mm, 2mm, 3mm, 4mm, 4.5mm, 6mm or other values between 0-6mm.

[0301] Referring to Figure 5 According to some embodiments of the present application, the thickness of the door body 12 can be 42mm-60mm.

[0302] Because the hinge assembly 13 of the present application has a compact structure, the door body 12 can be adapted as a super-thin door body 12, thereby reducing the space occupied by the door body 12 to the entire refrigeration equipment 1, and increasing the capacity of the entire refrigeration equipment 1 under the same volume, or reducing the thickness of the entire refrigeration equipment 1 under the same capacity.

[0303] Wherein, the thickness S of the door body 12 takes values in the range of [42mm, 60mm], exemplarily, S can take values of 42mm, 45mm, 47mm, 50mm, 52mm, 55mm, 58mm, 60mm or other values between 42mm-60mm, which are not specifically limited here.
