[0002] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a product that stores food at low temperatures to prevent it from spoiling quickly. It is widely used in daily life. Refrigerators can be divided into two types according to the different usage habits of their users. One type is placed freely in the kitchen or living room, which belongs to the traditional way of using refrigerators; the other type is fixedly embedded in the cabinet and placed in the kitchen. With the upgrading of consumption, this type of refrigerator is becoming more and more popular among consumers. In addition, this type of existing embedded refrigerator often touches the side wall of the cabinet when the refrigerator door is opened, which will cause damage to the door. Utility Model Content

[0003] Some embodiments of the present disclosure provide a refrigerator that can solve the problem of door damage when the door of an embedded refrigerator is opened.

[0004] The present disclosure provides a refrigerator, comprising:

[0005] A box body having a take-in and put-out opening; and

[0006] The door body is rotatably connected to the box body around a preset axis to open or close the access opening; the door body includes a first side wall and a third side wall arranged opposite to each other along the depth direction of the refrigerator, and a second side wall and a fourth side wall arranged opposite to each other along the width direction of the refrigerator, the first side wall is farther away from the box body than the third side wall, the second side wall is closer to the preset axis than the fourth side wall, and the first side wall and the second side wall are adjacent to each other and connected by a transition portion;

[0008] In some embodiments, the second side wall is flush with the box side wall, and the radius of the reference circle is the distance between the preset axis and the second side wall.

[0009] In some embodiments, the second side wall has a retracted distance relative to the box side wall in the width direction, and the radius of the reference circle is the sum of the distance between the preset axis and the second side wall and the retracted distance.

The requirements of built-in refrigerators can be met and the safety of the refrigerator during use is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0039] The inventor noticed that for a refrigerator embedded in a cabinet or other storage space in the kitchen, when the door body is rotated to open, the inner edge of the door body close to the box body moves inward, and the outer edge of the door body away from the box body will form a motion trajectory of an arc with the hinge axis as the rotation center. In the previous stage of the door body opening, the outer edge gradually approaches the box body in the depth direction of the refrigerator and gradually moves outward in the width direction. During this process, the outer edge will move to an extension surface beyond the side wall of the box body, thereby colliding with the wall of the cabinet or other storage space. In this way, the door body cannot be opened at too large an angle during use. If the opening angle is large, the door body will be damaged by collision, which makes it difficult to meet the use requirements of the built-in refrigerator.

[0040] In the case where a refrigerator is embedded in a storage space, it is generally desired to reduce the gap between the refrigerator and the side wall of the storage space, which not only reduces the space occupied, but also makes the refrigerator more beautiful and prevents more debris from falling into the gap. To meet this demand, the present disclosure provides an improved refrigerator.

[0041] In some embodiments, Figures 1 to 6 As shown, the refrigerator includes:

[0042] The box body 1 is provided with a take-in and put-out opening; and

[0043] The door body 2 is rotatably connected to the box body 1 around a preset axis O to open or close the access opening; the door body 2 includes a first side wall 21 and a third side wall 23 that are relatively arranged along the depth direction y of the refrigerator, and a second side wall 22 and a fourth side wall 24 that are relatively arranged along the width direction x of the refrigerator, the first side wall 21 is away from the box body 1 relative to the third side wall 23 along the depth direction y, the second side wall 22 is close to the preset axis O relative to the fourth side wall 24 along the width direction x, and the first side wall 21 and the second side wall 22 are adjacent and connected by a transition portion 4;

[0044] Among them, the second side wall 22 does not exceed the side wall 11 of the box body 1 along the width direction x of the refrigerator when the door body 2 is closed, and the transition portion 4 is configured not to exceed the reference circle K during the rotation of the door body 2, the center of the reference circle K is located on the preset axis O, and the radius of the reference circle K is the distance between the preset axis O and the side wall 11 along the width direction x.

[0045] Specifically, Figure 1 As shown, objects such as vegetables, fruits or meat can be stored in the box body 1 or taken out from the storage space of the box body 1 through the access opening. The door body 2 has a fixed rotation axis, and in the closed state, the access opening is closed.

[0046] The door body 2 has a first side wall 21 and a third side wall 23 which are arranged opposite to each other along the depth direction y, and a second side wall 22 and a fourth side wall 24 which are arranged opposite to each other along the width direction x, wherein the first side wall 21 is located on a side away from the box body 1, the third side wall 23 is located on a side close to the box body 1, the second side wall 22 is connected between the first side wall 21 and the third side wall 23 and is located on the outside, that is, on a side close to the preset axis O, and the fourth side wall 24 is connected between the first side wall 21 and the third side wall 23 and is located on a side away from the preset axis O. The depth direction y refers to a direction extending from the access opening to the inside of the storage space in a horizontal plane, and the width direction x is perpendicular to the depth direction y.

[0047] The second side wall 22 intersects with the extended surface of the first side wall 21 to form a first ridgeline L1, and the third side wall 23 intersects with the second side wall 22 to form a second ridgeline L2. There is a gap between the third side wall 23 and the box body 1 to prevent the second ridgeline L2 from interfering with the box body 1 when the door body 2 is opened.

[0048] If the transition portion 4 is not provided, the first ridge line L1 actually exists. After the transition portion 4 is provided, the area where the first ridge line L1 is located moves toward the inner area of ​​the door body 2, and the original first ridge line L1 becomes a virtual line. During the opening process of the door body 2, the second ridge line L2 moves inward along the width direction x and is always located inside the extension surface of the box side wall 11. As long as the motion trajectory of each point on the outer contour of the transition portion 4 does not exceed the extension surface of the box side wall 11, it can be ensured that the door body 2 does not exceed the extension surface of the box side wall 11 during the opening process.

[0049] The transition portion 4 extends along the height direction of the entire door body 2, and its outer contour shape can be designed based on factors such as processing convenience, strength and aesthetics of the door body 2, etc.

[0050] In the refrigerator of this embodiment, the second side wall 22 does not exceed the box side wall 11 when the door body 2 is closed, and a transition portion 4 is arranged on the outer side of the door body 2 at the edge away from the box body 1, and the transition portion 4 does not exceed the reference circle K during the rotation of the door body 2. Since the reference circle K is set to have the same rotation center as that when the door body 2 is opened, when the reference circle K does not exceed the extension surface of the box side wall 11, the outer contour of the transition portion 4 will not exceed the extension surface of the box side wall 11 during the opening of the door body 2. Even when the distance between the box body 1 and the side wall of the accommodating space is very small, the door can be opened normally, preventing the door body 2 from interfering with the side wall of the accommodating space during the opening process and failing to open properly, or from being damaged due to touching the side wall of the accommodating space. The requirements of built-in refrigerators can be met and the safety of the refrigerator during use is improved.

[0051] In some embodiments, Figure 2As shown, the second side wall 22 is flush with the box side wall 11 , and the radius of the reference circle K is the distance R between the preset axis O and the second side wall 22 .

[0052] Specifically, when the door body 2 is closed, the second side wall 22 and the box side wall 11 are located in the same plane, and the distance R between the preset axis O and the second side wall 22 is consistent with the distance between the preset axis O and the box side wall 11.

[0053] The refrigerator of this embodiment allows the preset axis O to move outward as much as possible along the width direction x, reducing the impact on the width of the refrigerator or freezer, and maximizing the storage capacity; moreover, after the refrigerator is embedded in the storage space, the gap between the door body 2 and the side wall of the storage space is small, which can make the connection and transition between the refrigerator and the storage space such as the cabinet more integrated and not easy to enter debris. Even if the gap between the door body 2 and the side wall of the storage space is small, the door can be opened normally, preventing the door body 2 from interfering with the side wall of the storage space during the opening process and failing to open in place, or causing damage due to touching the side wall of the storage space.

[0054] In some embodiments, Figure 4 and Figure 5 As shown, the second side wall 22 has a retracted distance H relative to the box side wall 11 along the width direction x, and the radius of the reference circle K is the sum of the distance R between the preset axis O and the second side wall 22 and the retracted distance H.

[0055] Among them, the second side wall 22 retracts inwardly relative to the box side wall 11 along the width direction x. For a single-door refrigerator, the width of the door body 2 is smaller than the width of the box body 1; for a double-door refrigerator, the total width of the two door bodies 2 is smaller than the width of the box body 1.

[0056] Since the radius of the reference circle K is R+H, the reference circle K does not exceed the extension surface of the box side wall 11, and the outer contour of the transition portion 4 does not exceed the extension surface of the box side wall 11 during the opening process of the door body 2.

[0057] This embodiment retracts the door body 2 inwards. For built-in refrigerators, since the gap between the box body 1 and the side wall of the storage space is small, it is not conducive to the heat dissipation of the refrigerator. By increasing the gap between the side of the door body 2 and the side wall of the storage space, a heat dissipation channel can be formed, thereby improving the heat dissipation effect of the built-in refrigerator. For this refrigerator, since the second side wall 22 of the door body 2 itself has been retracted inwards, the material removed to form the transition part 4 can be reduced, that is, the size of the transition part 4 can be reduced, and the structural strength of the door body 2 at the hinged part can be improved.

[0058] In some embodiments, Figures 2 to 4As shown, the extended surfaces of the first side wall 21 and the second side wall 22 intersect to form a first ridgeline L1, a first intersection point of the reference circle K and the first side wall 21 near the first ridgeline L1 has a first distance D1 from the first ridgeline L1, and a second intersection point of the reference circle K and the second side wall 22 near the first ridgeline L1 has a second distance D2 from the first ridgeline L1;

[0059] The transition portion 4 has a first edge 41 and a second edge 42 . The first edge 41 has a third distance d1 from the first ridgeline L1 . The second edge 42 has a fourth distance d2 from the first ridgeline L1 . The third distance d1 is not less than the first distance D1 . The fourth distance d2 is not less than the second distance D2 .

[0060] Among them, when the transition portion 4 has an obvious intersection line with the first side wall 21 and the second side wall 22, the first edge 41 and the second edge 42 are the intersection line, and when the transition portion 4 is tangent to the first side wall 21 and the second side wall 22 and transitions smoothly, the first edge 41 and the second edge 42 are at the tangent position.

[0061] This embodiment uses the first intersection point of the reference circle K with the first side wall 21 and the second intersection point with the second side wall 22 as two design boundary points. The two intersection points are located on the reference circle K. If the first edge 41 and the second edge 42 are located at the first intersection point and the second intersection point respectively, and the portion of the transition portion 4 between the first edge 41 and the second edge 42 is located within the reference circle K, then although the extension surface reaching the box side wall 11 will appear during the opening process of the door body 2, it can also meet the use requirements of the built-in refrigerator, and this method can minimize the material removed to form the transition portion 4, that is, reduce the size of the transition portion 4, and improve the structural strength of the door body 2 at the hinged portion.

[0062] Alternatively, in order to prevent the influence of the size and assembly errors of the door body 2, the third distance d1 is greater than the first distance D1, so that the first edge 41 is located on the side of the first intersection away from the first ridge line L1, and the fourth distance d2 is greater than the second distance D2, so that the second edge 42 is located on the side of the second intersection away from the first ridge line L1, and the transition portion 4 between the first edge 41 and the second edge 42 is located within the reference circle K, which can further improve the safety of the built-in refrigerator during the process of opening the door body 2.

[0063] In some embodiments, the third distance d1 is equal to the fourth distance d2, or the third distance d1 is smaller than the fourth distance d2.

[0064] If the third distance d1 is equal to the fourth distance d2, the material removed from the door body 2 around the hinge axis can be distributed more evenly, making it easier to ensure the structural strength of the door body 2. If the third distance d1 is smaller than the fourth distance d2, for a built-in refrigerator, while ensuring the safety of opening the door body 2, the gap between the first edge 41 and the side wall of the storage space can be minimized, and a better overall effect can be achieved with the storage space such as a cabinet when viewed from the outside.

[0065] In some embodiments, Figure 3 and Figure 5 As shown, the transition portion 4 includes a fillet 4A, the radius r of which is not less than the distance between the preset axis O and the box side wall 11 along the width direction x, that is, the radius r of the fillet 4A is not less than the radius of the reference circle K.

[0066] This embodiment is easy to process by setting a fillet 4A between the first side wall 21 and the second side wall 22, and can make the first side wall 21 and the second side wall 22 transition smoothly, and is not prone to stress concentration. Moreover, on the basis that the first edge 41 of the transition portion 4 does not exceed the first intersection point, and the second edge 42 does not exceed the second intersection point, the radius r of the fillet 4A is not less than the radius of the reference circle K, so that the curvature of the fillet 4A is not greater than the reference circle K, so that the fillet 4A will not exceed the reference circle K, and will not exceed the extension surface of the box side wall 11 during the opening process of the door body 2, which can meet the use requirements of the built-in refrigerator and improve the safety of the door body 2 opening process.

[0067] In some embodiments, the third distance d1 and the fourth distance d2 are constructed so that the distance from the preset axis O to the line connecting the first intersection and the second intersection is not less than a preset threshold value. Here, the "distance" can be determined as follows: in a cross section perpendicular to the height direction of the refrigerator, the reference circle K and the first side wall 21 form a first intersection near the first ridge line L1, and the reference circle K and the second side wall 22 form a second intersection near the first ridge line L1. A perpendicular line is drawn from the preset axis O to the line connecting the first intersection and the second intersection. The length of the perpendicular line segment is the distance from the preset axis O to the line connecting the first intersection and the second intersection.

[0068] The larger the third distance d1 and the fourth distance d2 are, the higher the safety of the door body 2 when it is opened. However, at the same time, more material needs to be removed in the area of ​​the first ridge line L1, which reduces the distance between the preset axis O and the outer contour of the transition portion 4, and weakens the local strength of the door body 2. The preset threshold value can be obtained by strength design or verification of the door body 2. In the case where the transition portion 4 is at an oblique angle and coincides with the connecting line to meet the strength requirements, the structure in which the transition portion 4 protrudes toward the first ridge line L1 can better meet the strength requirements.

[0069] Generally, the fourth distance d2 does not exceed half of the thickness of the refrigerator door 2.

[0070] In this embodiment, a line is connected between the first intersection point of the reference circle K and the first side wall 21 and the second intersection point of the reference circle K and the second side wall 22, and the distance from the preset axis O to the line is obtained. By limiting the minimum value of the distance, the maximum limit values ​​of the third distance d1 and the fourth distance d2 can be limited on the basis of meeting the opening requirements of the built-in refrigerator door 2, so as to ensure the structural strength of the door 2 and improve the service life of the refrigerator.

[0071] Moreover, in order to improve the thermal insulation effect of the refrigerator, a foam material is provided in the door body 2. By limiting the maximum values ​​of the third distance d1 and the fourth distance d2, the loss of the foam material layer can be reduced. On the basis of meeting the opening requirements of the built-in refrigerator door body 2, the thermal insulation performance of the refrigerator can be guaranteed to prevent the risk of condensation on the outside of the door body 2 and the box body 1.

[0072] In some embodiments, the transition portion 4 includes a rounded corner 4A or a chamfered corner 4B. In addition, the transition portion 4 may also adopt other shapes.

[0073] If the transition portion 4 of this embodiment adopts a rounded corner 4A, Figure 2 and Figure 3 As shown, it is easy to process and can make the first side wall 21 and the second side wall 22 transition smoothly, and it is not easy to generate stress concentration. In addition, the fillet 4A is concentric with the hinge shaft 32, so that the distance between the hinge shaft 32 and the outer contour of the transition part 4 is consistent at all places, and the outer periphery of the hinge shaft 32 has uniform structural strength. Figure 4 and Figure 5 As shown, the transition portion 4 is a plane connecting the first edge 41 and the second edge 42, which is easy to design without considering the bending curvature. Moreover, since more material is removed, the risk of collision with the side wall of the accommodating space during the opening process of the door body 2 can be further reduced.

[0074] In some embodiments, the door body 2 includes a frame body 25 , the first side wall 21 and the second side wall 22 are located on the frame body 25 , and the transition portion 4 is a rounded corner 4A or a chamfered corner 4B.

[0075] For example, the frame body may be made of metal material.

[0076] In this embodiment, the side and front sides of the door body 2 are both located on the frame body, which can make the frame of the door body 2 simpler to shape.

[0077] In some embodiments, Figure 6 As shown, the door body 2 includes a frame body 25 and a glass plate 26. The glass plate is attached to the side of the frame body 25 away from the box body 1 along the depth direction y, the first side wall 21 is located on the glass plate 26, the second side wall 22 is located on the frame body 25, the transition portion 4 is arranged on the frame body 25, and the glass plate 26 does not exceed the first edge 41 close to the first side wall 21 along the width direction x.

[0078] For example, the frame body can be made of metal material, and the glass plate covers the surface of the frame body 25 away from the box body 1, and the thickness of the glass plate is relatively thin. The transition portion 4 can be rounded 4A or chamfered 4B.

[0079] In this embodiment, the hardness of the glass plate 26 is relatively large and it is not easy to process it into a specific shape at the edge. Therefore, the transition part 4 is arranged on the frame body 25, which can reduce the difficulty of processing. In this structure, the frame body 25 and the glass plate 26 can still be designed as a whole to design the transition part 4, and the right-angle edge can be maintained when the glass plate 26 is not convenient to process. Since the sharp angle position of the first ridge line L1 is more likely to exceed the extension surface of the box side wall 11, the sharp angle area at the first ridge line L1 has been removed by setting the transition part 4. During the opening process of the door body 2, the transition part 4 located on the frame body 25 will not exceed the extension surface of the side wall 11; although the glass plate 26 maintains a right-angle edge and there is a small amount of material protruding from the transition part 4, the thickness ratio of the glass plate 26 to the frame body 25 is very small, and the end of the glass plate 26 along the refrigerator width direction x is at a certain distance from the first ridge line L1. Therefore, when the door body 2 is opened, the part of the end of the glass plate 26 protruding from the transition part 4 will not exceed the extension surface of the side wall 11. Through analysis, this embodiment can still ensure the safety of opening the door.

[0080] In some embodiments, Figure 1 and 2 As shown, the refrigerator further includes: at least two hinges 3, and hinges 3 are provided at both ends of the door body 2 along the preset axis O, and the hinges 3 are configured to connect the door body 2 and the cabinet 1. By arranging the hinges 3 at the top and bottom ends of the door body 2, the door body 2 can be stably rotated around the preset axis O. The hinges 3 are arranged at a position close to the outer side of the door body 2 along the width direction.

[0081] For example, the hinge 3 includes a mounting plate 31 and a hinge shaft 32, wherein the mounting plate 31 is connected to the end face of the box body 1, the mounting plate 31 extends beyond the side face of the box body 1 and covers at least part of the end face of the door body 2, and the hinge shaft 32 is connected to the mounting plate 31 and inserted into the hinge hole on the end face of the door body 2. One end of the mounting plate 31 is fixed to the top wall or the bottom wall of the box body 1, and the other end of the mounting plate 31 covers the top wall or the bottom wall of the door body 2. Specifically, the mounting plate 31 includes a first part and a second part, wherein the first part is mounted to the box body 1 by fasteners, and the second part is connected to the first part. In order to adapt to the setting position of the preset axis O, the second part can be deflected relative to the first part along the width direction x toward the second side wall 22, and the second part can be in a shape with a gradually decreasing width from the connection with the first part to the hinge shaft 32.

[0082] In some embodiments, Figure 1As shown, two door bodies 2 are provided, and the two door bodies 2 can be opened and closed relative to each other to jointly close the access opening in the closed state, and each door body 2 is connected to the box body 1 through two hinges 3. The hinges 3 of the two door bodies 2 are located at both ends of the box body 1 along the width direction x. Optionally, one door body 2 can also be provided.

[0083] The embodiment of the present disclosure can realize the embedded installation of the refrigerator by arranging a transition portion 4 of a suitable shape and size on the door body 2. According to the usage, the zero-embedded installation method and the flush-embedded installation method can be selected. The zero-embedded installation means that the refrigerator is seamlessly embedded in a storage space such as a cabinet. For example, there is no gap between the side and top surfaces of the refrigerator and the inner walls of the storage space, and the door body 2 is allowed to protrude the front end surface of the storage space; the flush-embedded installation means that the first side wall 21 of the refrigerator door body 2 is installed flush with the end surface of the storage space, allowing a gap to exist on the side or top surface of the refrigerator.

[0084] Two embodiments are given below for illustration.

[0085] In the first embodiment, if Figure 2 and Figure 3 As shown, when the retracted distance H=0, that is, the second side wall 22 is flush with the box side wall 11, the axis of the hinge shaft 32 is taken as the center of the circle, and the distance R between the preset axis O and the second side wall 22 is taken as the radius as a reference circle K, forming a first intersection with the first side wall 21 and a second intersection with the second side wall 22.

[0086] When the transition portion 4 is a chamfer 4B, the third distance d1 is not less than the first distance D1, and the fourth distance d2 is not less than the second distance D2, that is, d1≥D1, d2≥D2, and the door body 2 will not exceed the box side wall 11 when rotating.

[0087] When the transition portion 4 is a rounded corner 4A, d1≥D1, d2≥D2 are satisfied at the same time, and the radius r of the rounded corner 4A is not less than the radius of the reference circle K, that is, r≥R, and the door body 2 will not exceed the box side wall 11 when rotating.

[0088] The first embodiment has the following technical effects: the refrigerator of this embodiment allows the preset axis O to move outward as much as possible along the width direction x, reducing the impact on the width of the refrigerator or freezer, and maximizing the storage capacity; moreover, after the refrigerator is embedded in the storage space, the gap between the door body 2 and the side wall of the storage space is small, which can make the connection and transition between the refrigerator and the storage space such as the cabinet more integrated and not easy to enter debris. Even if the gap between the door body 2 and the side wall of the storage space is small, the door can be opened normally, preventing the door body 2 from interfering with the side wall of the storage space during the opening process and failing to open in place, or causing damage due to touching the side wall of the storage space.

[0089] In the second embodiment, if Figure 4 and Figure 5As shown, when the retraction distance H>0, that is, the second side wall 22 is retracted inwardly than the inner side wall 11 of the box in the width direction x, a reference circle K is made with the axis of the hinge shaft 32 as the center of the circle, and the sum of the distance R between the preset axis O and the second side wall 22 and the retraction distance H (H+R) as the radius, forming a first intersection with the first side wall 21 and a second intersection with the second side wall 22.

[0090] When the transition portion 4 is a chamfer 4B, the third distance d1 is not less than the first distance D1, and the fourth distance d2 is not less than the second distance D2, that is, d1≥D1, d2≥D2, and the door body 2 will not exceed the box side wall 11 when rotating.

[0091] When the transition portion 4 is a rounded corner 4A, d1≥D1, d2≥D2 are satisfied at the same time, and the radius r of the rounded corner 4A is not less than the radius of the reference circle K, that is, r≥R+H, and the door body 2 will not exceed the box side wall 11 when rotating.

[0092] The second embodiment has the following technical effects: this embodiment allows the door body 2 to retract inwards. For built-in refrigerators, since the gap between the box body 1 and the side wall of the storage space is small, it is not conducive to the heat dissipation of the refrigerator. By increasing the gap between the side of the door body 2 and the side wall of the storage space, a heat dissipation channel can be formed, thereby improving the heat dissipation effect of the built-in refrigerator. For this refrigerator, since the second side wall 22 of the door body 2 itself has retracted inwards, the material removed to form the transition portion 4 can be reduced, that is, the size of the transition portion 4 can be reduced, and the structural strength of the door body 2 at the hinged part can be improved.

[0093] The above two embodiments can meet the requirements of built-in refrigerators through design adjustments based on current non-built-in refrigerators, that is, a transition portion 4 is added to the outer corner of the door body 2 to prevent the door body 2 from exceeding the box side wall 11 and interfering with the side wall of the installation space during the rotation process, resulting in the door body being unable to open or being damaged. When designed according to the size requirements mentioned in the above embodiments, even if the distance between the box body 1 and the side wall of the accommodating space is very small, the door body 2 can be opened normally, which can improve the safety of opening the door.

[0094] Secondly, the present disclosure provides a design method for a refrigerator based on the above embodiment, which in some embodiments includes:

[0095] A reference circle K is set, the center of which is located on the preset axis O, and the radius of which is the distance between the preset axis O and the box side wall 11 along the width direction x;

[0096] A transition portion 4 is provided at the connection between the first side wall 21 and the second side wall 22 , and the movement trajectory of the transition portion 4 does not exceed the reference circle K during the opening process of the door body 2 .

[0097] In the refrigerator design method of this embodiment, the transition portion 4 does not exceed the reference circle K during the rotation of the door body 2. Since the reference circle K is set to have the same rotation center as that when the door body 2 is opened, when the reference circle K does not exceed the extension surface of the box side wall 11, the outer contour of the transition portion 4 will not exceed the extension surface of the box side wall 11 during the opening of the door body 2. Even when the distance between the box body 1 and the side wall of the accommodating space is very small, the door can be opened normally, preventing the door body 2 from interfering with the side wall of the accommodating space during the opening process and failing to open properly, or from being damaged by touching the side wall of the accommodating space. The requirements of a built-in refrigerator can be met, and the safety of the refrigerator during use is improved.

[0098] In some embodiments, the step of setting the transition portion 4 includes:

[0099] The extended surfaces of the first side wall 21 and the second side wall 22 intersect to form a first ridge line L1;

[0100] Obtaining a first distance D1 between a first intersection point of the reference circle K and the first side wall 21 near the first ridge line L1 and the first ridge line L1;

[0101] It is obtained that the second intersection point of the reference circle K and the second side wall 22 near the first ridge line L1 is at a second distance D2 from the first ridge line L1;

[0102] The third distance d1 between the first edge 41 of the transition portion 4 and the first ridge line L1 is not less than the first distance D1;

[0103] The fourth distance d2 between the second edge 42 of the transition portion 4 and the first ridgeline L1 is not less than the second distance D2.

[0104] In the design method of this embodiment, the first intersection point of the reference circle K with the first side wall 21 and the second intersection point with the second side wall 22 are used as two design boundary points, and the two intersection points are located on the reference circle K. If the first edge 41 and the second edge 42 are located exactly at the first intersection point and the second intersection point respectively, and the transition portion 4 between the first edge 41 and the second edge 42 is located within the reference circle K, the extension surface of the box side wall 11 will be reached during the opening of the door body 2, which can meet the use requirements of the built-in refrigerator. Or in order to prevent the influence of the size and assembly errors of the door body 2, the third distance d1 is greater than the first distance D1, so that the first edge 41 is located on the side of the first intersection away from the first ridge line L1, the fourth distance d2 is greater than the second distance D2, so that the second edge 42 is located on the side of the second intersection away from the first ridge line L1, and the transition portion 4 between the first edge 41 and the second edge 42 is located within the reference circle K, which can further improve the safety of the built-in refrigerator during the opening of the door body 2.

[0105] In some embodiments, the transition portion 4 is a rounded corner 4A, and the steps of providing the transition portion 4 include:

[0106] The radius r of the rounded corner 4A is not less than the distance between the preset axis O and the box side wall 11 along the width direction x.

[0107] This embodiment is easy to process by setting a fillet 4A between the first side wall 21 and the second side wall 22, and can make the first side wall 21 and the second side wall 22 transition smoothly, and is not prone to stress concentration. Moreover, on the basis that the first edge 41 of the transition portion 4 does not exceed the first intersection point, and the second edge 42 does not exceed the second intersection point, the radius r of the fillet 4A is not less than the radius of the reference circle K, so that the curvature of the fillet 4A is not greater than the reference circle K, so that the fillet 4A will not exceed the reference circle K, and will not exceed the extension surface of the box side wall 11 during the opening process of the door body 2, which can meet the use requirements of the built-in refrigerator and improve the safety of the door body 2 opening process.
