Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a refrigerator. Background Art

[0002] Built-in refrigerators are typically built entirely into a custom cabinet. To ensure a seamless fit, the gap between the refrigerator's exterior and the cabinet's interior is typically kept very small. Consequently, when the refrigerator door is opened, the hinged vertical edge can easily strike the cabinet's interior wall. Due to the cabinet's limited space, to ensure the door opens efficiently, the door's corners must not extend significantly beyond the cabinet's dimensions.

[0003] Currently, to meet the needs of embedded installations, most systems employ dual shafts on one of the door and the housing, and a guide structure on the other to control the inward movement of the door as it rotates open. The combination of the dual shafts and the guide structure allows the door to move inward during opening, ensuring that the corners of the door do not extend significantly beyond the dimensions of the housing.

[0004] When customizing the cabinet in which the built-in refrigerator is embedded, one of the standards is usually that the front wall of the refrigerator door is flush with the plane of the cabinet opening when the refrigerator door is closed, so that the size of the refrigerator matches the size of the cabinet and a hidden flush installation is achieved. In addition, another standard is that the distance between the inner wall of the cabinet and the outer wall of the refrigerator or the side wall of the door when the door is closed meets the minimum value for installing the refrigerator in the cabinet, so that the refrigerator can fully utilize the installation space limited by the cabinet and achieve installation with no or small gaps. Under the premise that the door of the built-in refrigerator can be opened smoothly without interfering with the inner wall of the cabinet, as the opening angle of the refrigerator door increases, the front wall of the door approaches the end of the adjacent cabinet near its opening; when the front wall of the door contacts the end of the adjacent cabinet near its opening, the door is opened to the limit position. In summary, the maximum opening angle of the refrigerator door installed in the storage cabinet is limited by the size of the storage cabinet for realizing the hidden installation of the refrigerator and the gap between the door side wall and the inner wall of the storage cabinet when the outer wall or door body of the refrigerator is closed. The maximum opening angle of the refrigerator door installed in the storage cabinet is small, which is inconvenient for users to take and put items. Summary of the Invention

[0107] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0108] The terms "first," "second," "third," "fourth," and "fifth" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the quantity of the technical features indicated. Therefore, a feature specified as "first," "second," "third," "fourth," or "fifth" may explicitly or implicitly include one or more of such features.

[0109] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0110] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings. In the accompanying drawings, the side of the refrigerator facing the user when in use is defined as the front side, and the side opposite thereto is defined as the rear side.

[0111] Reference Figure 1 The refrigerator includes a cabinet 10 having a storage chamber, and a door 30 connected to the cabinet 10 to open and close the storage chamber.

[0112] In some embodiments of the present application, the housing 10 defines multiple storage compartments for storing items. A storage compartment has an access opening formed at the front end for placing food into or removing food from the compartment. The refrigerator includes a refrigeration device that supplies cold air to the compartments, thereby keeping the items stored therein at low temperatures. The housing 10 is provided with a rotatable door 30 to open and close the access openings to the storage compartments.

[0113] Specifically, the door body 30 is rotatably connected to the box body 10 through a hinge assembly located at the upper portion and / or a hinge assembly located at the lower portion.

[0114] In some embodiments of the present application, the hinge assembly includes a first hinge component and a second hinge component, and the first hinge component and the second hinge component cooperate with each other and can rotate relative to each other.

[0115] The housing 10 includes a first side wall and a second side wall (i.e., the left and right side walls of the housing 10) that are arranged opposite to each other. A first hinge is arranged on the housing 10 and close to the first side wall, and a second hinge is arranged at the end of the door 30 close to the first hinge. The first hinge cooperates with the second hinge to allow the housing 10 and the door 30 to rotate relative to each other. The door 30 includes a front door wall 31 that is away from the housing 10 when the door 30 is closed, a rear door wall 33 that is arranged opposite to the front door wall 31, and a side door wall 32 that is close to the first hinge and connected to the front door wall 31. For example, when the first hinge is located on the right side of the housing 10, the right side of the door 30 when closed serves as the side door wall 32. When the first hinge is located on the left side of the housing 10, the left side of the door 30 when closed serves as the side door wall 32.

[0116] The front wall 31 and the side wall 32 of the door body 30 intersect to form a first side edge W, and the side wall 32 and the rear wall 33 intersect to form a second side edge N. When the door body 30 is closed, the first side edge W is located on the side of the second side edge N away from the box body 10.

[0117] It should be noted that when the door front wall 31 and the door side wall 32 are both planes, the intersection line of the two planes is the theoretical first side edge W. Similarly, the theoretical second side edge N is the intersection line of the door side wall 32 and the door rear wall 33.

[0118] In actual production and processing, the intersection of the door front wall 31 and the door side wall 32 is configured with a rounded transition, thereby forming a curved surface at the intersection of the door front wall 31 and the door side wall 32. On the curved surface at the intersection of the door front wall 31 and the door side wall 32, any straight line extending along the height direction of the door body 30 can be regarded as the first side edge W (the same applies to the second side edge N). For the sake of convenience, the description in this application is based on the theoretical first side edge W and the theoretical second side edge N.

[0119] In some embodiments of the present application, a door seal 5 is provided on the door rear wall 33. When the door 30 is closed, the door seal 5 abuts against the front face of the box body surrounding the access opening, effectively sealing the connection between the door 30 and the box body 10. This ensures that the door 30 seals the access opening and prevents cold air from escaping. Optionally, the door seal 5 is annular. The door seal 5 is located between the door rear wall 33 and the front face of the box body, with the door rear wall 33 located on the side of the box body 10 near the access opening.

[0120] In some embodiments of this application, refer to Figures 1 to 2 and Figure 34 The first hinge member includes a hinge plate 40, a first shaft 41, and a second shaft 42 disposed on the hinge plate 40. The hinge plate 40 includes a connecting portion 401 connected to the housing 10 and proximate to the side wall of the first housing, and an extending portion 402 extending forward from the connecting portion 401. The connecting portion 401 can be fastened to the top wall of the housing 10 using fasteners such as screws, pins, and bolts. The extending portion 402 is in the shape of a horizontal plate.

[0121] Specifically, for the hinge at the upper end of the door body 30, the connecting portion 401 is connected to the top wall of the box body 10. For the hinge at the lower end of the door body 30, the connecting portion 401 is connected to the front end surface of the box body 10. A first axis 41 and a second axis 42 are formed on the extension portion 402 of the first hinge member. The second axis 42 is located on the side of the first axis 41 away from the side wall of the first body.

[0122] The second hinge member includes a guide portion 50 and a guide portion 60 located near the end of the door body 30 near the first hinge member. A first shaft 41 mates with the guide portion 50, and a second shaft 42 mates with the guide portion 60. When the door body 30 rotates to open or close, the first shaft 41 moves relative to the guide portion 50, and the second shaft 42 moves relative to the guide portion 60.

[0123] The first shaft 41 and the second shaft 42 are formed on the first hinge member connected to the box body 10 to form a limited axis for guiding the movement of the door body 30. Specifically, the first shaft 41 and the second shaft 42 extend in the vertical direction (the height direction of the box body 10) to adapt to the guide portion 50 or the guide portion 60 provided on the door body 30.

[0124] A built-in refrigerator is one in which the entire refrigerator is embedded within a custom-made storage cabinet 100. The end face of the storage cabinet 100 defining its opening is referred to as the opening end face. The refrigerator is flushly embedded within the storage cabinet 100. When the refrigerator door is closed, the front wall 31 of the door 30 is flush with the opening end face of the storage cabinet 100. In the present invention, the first shaft 41 cooperates with the guide portion 50, and the second shaft 42 cooperates with the guide portion 60 to move the door 30 inward a certain distance. This prevents the refrigerator door 30 from colliding with the storage cabinet 100 when the user opens or closes the refrigerator door 30, effectively preventing damage to the storage cabinet 100 or the refrigerator door.

[0125] It should be noted that the term "flush" in the above description of the door front wall 31 being flush with the open end face of the storage cabinet 100 includes being on the same plane, or having a distance of no more than 2 mm between the two planes. Specifically, the door front wall 31 can be located on the side of the open end face of the storage cabinet 100 away from the access opening, with the distance between the two planes no more than 2 mm. Alternatively, the door front wall 31 can be located on the side of the open end face of the storage cabinet 100 closer to the access opening, with the distance between the two planes no more than 2 mm.

[0126] In some embodiments of the present application, the first and second shafts 41, 42 are provided on the extensions 402 at the upper and lower ends of the door body 30, and the guides 50 and 60 are provided at the upper and lower ends of the door body 30. It should be noted that the configuration of this embodiment is not limited to being provided at both the upper and lower ends of the door body 30, and is provided as needed to connect the door body 30 and the box body 10.

[0127] In some embodiments of the present application, Figure 1 As shown, the plane where the side surface (first body side wall) of the box body 10 close to the hinge plate 40 is located is defined as the reference plane M0, the side of the reference plane M0 away from the inner cavity of the storage chamber is recorded as the outer side, and the opposite side close to the inner cavity of the storage chamber is recorded as the inner side.

[0128] When the refrigerator is placed in the storage cabinet 100 for use, to prevent factors such as uneven ground and deformation of the storage cabinet 100, the distance α' between the storage cabinet 100 and the side of the refrigerator (the first side wall, i.e., the reference plane M0) is set when the storage cabinet 100 is sized. To ensure that the refrigerator door 30 opens properly, the first side edge W of the door 30 cannot extend too far beyond the side of the refrigerator body 10 (the reference plane M0) during rotation to prevent the first side edge W from colliding with the storage cabinet 100 and preventing the door 30 from opening properly.

[0129] In some embodiments of the present application, α' is any value between 3 and 5 mm.

[0130] In some embodiments of the present application, α`=3 mm; that is, the distance between the door side wall of the door body 30 and the storage cabinet 100 is 3 mm.

[0131] To meet the above requirements, the door body 30 needs to be able to move inward during rotation so that the first side edge W does not extend too far beyond the side wall (reference plane M0) of the box body 10. For example, if the hinge plate 40 is located on the right side of the door body 30 (in this example, the right side wall of the box body 10 is the first body side wall), the inner side is the left side, which means the door body 30 needs to be able to move to the left. For example, if the hinge plate 40 is located on the left side of the door body 30, the inner side is the right side, which means the door body 30 needs to be able to move to the right.

[0132] In some embodiments of the present application, the central axis of the first shaft 41 is recorded as the first central axis P, and the central axis of the second shaft 42 is recorded as the second central axis Q.

[0133] In some embodiments of the present application, Figure 1 As shown, in the projection of the top wall of the box body 10, the second central axis Q is located on the side of the first central axis P away from the plane where the first body side wall and the access opening are located.

[0134] In some embodiments of the present application, in the projection of the top wall of the box body 10, the second center axis Q is located on the side of the first center axis P away from the first body side wall and the pick-up and release port, and the angle between the second center axis Q and the straight line QP where the first center axis P is located and the first body side wall is recorded as β.

[0135] β is not less than a first reference value. The first reference value is between 60° and 70°. The first reference value can be 60°, 65°, or 70°. That is, β≥60°, β≥65°, or β≥70°.

[0136] When β ≥ 60°, the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30. When β ≥ 65°, the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30. When β ≥ 70°, the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30.

[0137] β is not greater than a second reference value. The second reference value is between 75° and 85°. The second reference value can be 75°, 80°, or 85°. That is, β≤75°, β≤80°, or β≤85°.

[0138] When β ≤ 75°, the strength requirements of the guide portions 50 and 60, the first shaft 41, and the second shaft 42 are better met. When β ≤ 80°, the strength requirements of the guide portions 50 and 60, the first shaft 41, and the second shaft 42 are better met. When β ≤ 85°, the strength requirements of the guide portions 50 and 60, the first shaft 41, and the second shaft 42 are met.

[0139] β is too small, and the distance between the first center axis P and the second center axis Q in the direction perpendicular to the front wall 31 of the door is too large; the guide part 50 cooperating with the first axis 41 and the guide part 42 cooperating with the second axis 42 occupy an increased size in the thickness direction of the door body 30, resulting in an increase in the thickness of the door body 30, which is not suitable for ultra-thin door bodies 30.

[0140] If β is too large, the distance between the first center axis P and the second center axis Q in the direction perpendicular to the door front wall 31 will be too small. The guide portion 50 and the guide portion 60 will be arranged too compactly. To prevent the guide portions 60 of the guide portion 50 from intersecting, as a method, the track width of the guide portion 50 that cooperates with the first shaft 41 and the guide portion 60 that cooperates with the second shaft 42 can be reduced. This requires reducing the diameters of the first shaft 41 and the second shaft 42. However, reducing the diameters of the first shaft 41 and the second shaft 42 reduces their strength, which can easily lead to damage and failure of the hinge assembly. Alternatively, if the diameters of the first shaft 41 and the second shaft 42 are maintained to ensure their strength, the minimum distance (minimum wall thickness) between the guide portion 50 and the guide portion 60 will be reduced, resulting in a reduction in the strength of the guide portion 50 and the guide portion 60.

[0141] In some embodiments of the present application, the guide portion 50 is configured as a guide groove, and the guide portion 60 is configured as a guide groove.

[0142] In some embodiments of the present application, the guide groove is a curved groove or a straight groove. The guide groove is a curved groove. The guide groove is located on a side of the guide groove close to the first side edge W.

[0143] In some embodiments of the present application, when the guide groove is configured as a curved groove, the guide groove protrudes toward the side close to the second side edge N.

[0144] In some embodiments of the present application, the distance between the guide groove and the door side wall 32 gradually decreases along the direction from the door rear wall 33 to the door front wall 31 .

[0145] In some embodiments of the present application, the trajectory of the relative motion of the first central axis P guided by the guide portion 50 is a guide trajectory S. The trajectory of the relative motion of the second central axis Q guided by the guide portion 60 is a guide trajectory K. The guide trajectory S is located on a side of the guide trajectory K close to the first side edge W.

[0146] The guide trajectory line S is a straight line or a curve.

[0147] In some embodiments of the present application, the guide trajectory line S is the center trajectory line of the guide portion 50 , and the guide trajectory line K is the center trajectory line of the guide portion 60 .

[0148] When the guide portion 50 is configured as a guide groove structure, the center trajectory line of the guide groove is the guide trajectory line S. When the guide portion 60 is configured as a guide groove structure, the center trajectory line of the guide groove is the guide trajectory line K.

[0149] In some embodiments of the present application, along a direction from an end of the door body 30 away from the door side wall 32 toward the door side wall 32 , a distance between the guide trajectory line S and the door front wall 31 gradually decreases.

[0150] In some embodiments of the present application, the guide track line S extends from one end thereof away from the door side wall 32 to a side close to the door front wall 31 and the door side wall 32 .

[0151] The guide track line K extends from the side close to the door side wall 32 to the side away from the door front wall 31 and the door side wall 32, then extends in the direction away from the door side wall 32 and close to the door front wall 31, and then extends to the side close to the door front wall 31 and the door side wall 32.

[0152] The guide track line K extends from its end away from the door side wall 32 first in a direction away from the door front wall 32 and the door side wall 31, then extends in a direction away from the door front wall 31 and close to the door side wall 32, and then extends in a direction close to the door front wall 31 and the door side wall 32.

[0153] The guide track line K includes an initial guide segment, a first guide segment connected to an end of the initial guide segment away from the door side wall 32 , and a second guide segment connected to an end of the first guide segment away from the door side wall 32 .

[0154] The initial guide section extends from its end close to the door side wall 32 in a direction away from the door front wall 31 and the door side wall 32. The first guide section extends from the end of the initial guide section away from the door side wall 32 in a direction close to the door front wall 31 and away from the door side wall 32. The second guide section extends from the end of the first guide section close to the door side wall 32 in a direction close to the door side wall 32 and the door front wall 31.

[0155] In some embodiments of the present application, Figure 1 As shown, in the projection of the plane where the top wall of the box body 10 (door body 30) is located, the door side wall 32 is the Y axis, and the plane passing through the first side edge W and perpendicular to the door side wall 32 is the X axis, that is, the plane where the door front wall 31 is located is the X axis (it can be set that the door front wall 31 is perpendicular to the door side wall 32); wherein, the X axis is perpendicular to the Y axis and intersects at the origin O (the first side edge W). The direction from the door front wall 31 to the door rear wall 33 is the positive direction of the Y axis, and the direction from the door side wall 32 to the end of the door body 30 opposite to the door side wall 32 is the positive direction of the X axis, forming a two-dimensional door body coordinate system XOY. It should be noted that the door body coordinate system XOY is a two-dimensional coordinate system that is stationary relative to the door body 30.

[0156] In the door body coordinate system XOY, the function corresponding to the guide trajectory line S in the coordinate system XOY is recorded as Y=F(X).

[0157] The first derivative of Y=F(X) is denoted as F` x , F` x > 0. Y = F(X) is a monotonically increasing function.

[0158] In some embodiments of the present application, the second-order derivative of Y=F(X) is denoted as F`` x , F`` x = 0. Y = F(X) is a linear function.

[0159] In some embodiments of the present application, the second-order derivative of Y=F(X) is denoted as F`` x , F`` x > 0. Y = F(X) is a convex upward function.

[0160] In some embodiments of the present application, when the door body 30 is in a closed state, the second shaft 42 is located on a side of the first shaft 41 away from the second side edge N. The guide portion 60 is located on a side of the guide portion 50 away from the first side edge W.

[0161] Since the guide portion 50 and the first shaft 41, as well as the guide portion 60 and the second shaft 42, are in relative motion, if the door body 30 is opened, with the guide portion 50 and the guide portion 60 as stationary reference objects, it is equivalent to the first shaft 41 moving under the restriction of the guide portion 50, and the second shaft 42 moving under the restriction of the guide portion 60. For the sake of convenience, this application uses the guide portion 50 and the guide portion 60 as stationary reference objects, and the first shaft 41 and the second shaft 42 move relative to the stationary reference objects for explanation.

[0162] In some embodiments of the present application, in the projection of the plane where the top wall of the box 10 is located, the line segment PQ is recorded as the axis line segment PQ; the center of the axis line segment PQ is recorded as the axis center point I. Figure 2-Figure 18 As shown, the movement of the first axis 41 along the guide portion 50 is equivalent to the movement of the first center axis P along the guide trajectory S, and the movement of the second axis 42 along the guide portion 60 is equivalent to the movement of the second center axis Q along the guide trajectory K, so that the door body 30 can move a certain distance inward (toward the side wall of the second body) while rotating, so that the door body 30 does not interfere with the storage cabinet 100, ensuring that the door body 30 is effectively opened.

[0163] Under the above setting, the door body 30 opens from the first angle G1 to the tenth angle G 10During this process, the first axis 41 moves entirely relative to the guide portion 50, the second axis 42 moves entirely relative to the guide portion 60, and the door body 30 rotates entirely around a point (axis center point I) that remains dynamically changing relative to the door body 30. Under the above configuration, as the door body 30 opens, the first center axis P moves relative to the guide trajectory S, and the second center axis Q moves relative to the guide trajectory K, rotating about axis center point I as the instantaneous rotation center. The instantaneous rotation center of the door body 30 is axis center point I. The position of axis center point I relative to the door body 30 continuously changes, and the position of the instantaneous rotation center of the door body 30 continuously changes.

[0164] It should be noted that, different from the above configuration, only the center axis of the first shaft 41 is used as the instantaneous rotation center axis of the rotational motion, the first center axis P, rather than the axis center point I.

[0165] The movement of the door 30 relative to the box 10 is equivalent to the relative movement of the door 30 and the box 10 within the plane of the top wall of the box 10 (or within the plane perpendicular to the first side edge W or the second side edge N). In other words, the movement of the door 30 relative to the box 10 can be attributed to relative movement within a two-dimensional plane.

[0166] Since the first hinge member having the first axis 41 and the second axis 42 is fixed on the box body 10, and the second hinge member having the guide portion 50 and the guide portion 60 is located on the door body 30, within the plane where the top wall of the box body 10 is located, the movement of the first hinge member (axial line segment PQ) relative to the door body 30 (guide portion 50 and guide portion 60) is equivalent to the movement of the axial line segment PQ relative to the door body 30, and is also equivalent to the movement of the box body 10 relative to the door body 30.

[0167] In the following description, for ease of illustration, the movement of the axial line segment PQ relative to the second hinge member (the guide portion 50 and the guide portion 60) provided on the door body 30 within the plane of the top wall of the box body 10 is used to represent the movement of the box body 10 relative to the door body 30. That is, the description of relative movement in this utility model is based on relative movement within a two-dimensional plane.

[0168] Indicates the opening angle of the door body 30. When the door body 30 is in the closed state, the opening angle of the door body 30 is recorded as the closing angle G G .

[0169] In some embodiments of the present application, The door front wall 31 is parallel to the plane where the take-in / put-out opening is located.

[0170] In some embodiments of the present application, The door rear wall 33 is perpendicular to the plane where the access opening is located.

[0171] In some embodiments of the present application, The door side wall 32 is parallel to the plane where the access opening is located.

[0172] The door 30 is opposite to the box 10. Opening angle when opening to open the access opening Is a positive number; the door body 30 is closed in the direction When the movement continues to further squeeze the door seal, the opening angle of the door body 30 becomes a negative number.

[0173] In some embodiments of the present application, G G =0°. That is, when the door body 30 is in the closed state, the opening angle It should be noted that the angle G at which the door body 30 is in the closed state is G Not affected by G G =0° limit.

[0174] like Figure 2-Figure 3 and Figure 12 As shown, under the constraints of the guide portion 50 and the first shaft 41, and the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a first stage. The first stage is as follows:

[0175] In some embodiments of the present application, the guide trajectory line S has a first guide point P1 and a second guide point P2 that are sequentially close to the door side wall 32 .

[0176] The first guiding point P1 and the second guiding point P2 are sequentially spaced away from the door front wall 31. That is, the distances between the first guiding point P1 and the second guiding point P2 and the door front wall 31 are sequentially increased.

[0177] The guide trajectory line S extends from the first guide point P1 to a side away from the door side wall 32 to a second guide point P2.

[0178] The guide trajectory line S extends from the first guide point P1 to a side away from the door front wall 31 to a second guide point P2.

[0179] The guide trajectory line S extends from the first guide point P1 to a second guide point P2 in a direction away from the door side wall 32 and the door front wall 31 .

[0180] In some embodiments of the present application, the guide track line K has a first guide point Q1 and a second guide point Q2 that are sequentially away from the door side wall 32 .

[0181] The first guide point Q1 and the second guide point Q2 are sequentially spaced away from the door front wall 31. That is, the distances between the first guide point Q1 and the second guide point Q2 and the door front wall 31 increase sequentially.

[0182] The guide track line K extends from the first guide point Q1 to a side away from the door side wall 32 to a second guide point Q2.

[0183] The guide track line K extends from the first guide point Q1 to a side away from the door front wall 31 to a second guide point Q2.

[0184] The guide track line K extends from the first guide point Q1 to a second guide point Q2 in a direction away from the door side wall 32 and the door front wall 31 .

[0185] When the door body 30 opens from the first angle G1 to the second angle G2 , the first central axis P moves toward a side away from the door front wall 31 and the door side wall 32 .

[0186] When the door body 30 opens from the first angle G1 to the second angle G2, the second central axis Q moves away from the door front wall 31 and the door side wall 32. The first angle G1 is smaller than the second angle G2.

[0187] When the door body 30 opens from the first angle G1 to the second angle G2 , the first central axis P moves from the first guiding point P1 to the second guiding point P2 .

[0188] When the door body 30 opens from the first angle G1 to the second angle G2 , the second central axis Q moves from the first guide point Q1 to the second guide point Q2 .

[0189] In some embodiments of the present application, the first angle G1 is smaller than the second angle G2.

[0190] In some embodiments of the present application, when the door body 30 opens from the first angle G1 to the second angle G2, the center point I of the axis moves from the first center point I1 to the side away from the door front wall 31 and the door side wall 32 to the second center point I2.

[0191] When the door body 30 opens from the first angle G1 to the second angle G2 , the center point I of the axis moves toward a side away from the door front wall 31 and the door side wall 32 .

[0192] During the first stage of opening, the door 30 opens at an angle of When , the first central axis P is located at the first guiding point P1 of the guiding trajectory line S, the second central axis Q is located at the first guiding point Q1 of the guiding trajectory line K, and the midpoint of the axis is located at the first midpoint I1.

[0193] Door body 30 opening angle When , the first central axis P is located at the second guide point P2 of the guide trajectory line S, the second central axis Q is located at the second guide point Q2 of the guide trajectory line K, and the midpoint of the axis is located at the second midpoint I2.

[0194] In some embodiments of the present application, G G =G1.

[0195] In some implementations of the present application, the first angle G1 = 0°.

[0196] In some embodiments of the present application, G G = G1 = 0°. At this time, when the door body 30 is opened at the first angle G1 = 0°, the door body 30 is in a closed state.

[0197] The first stage is the process of the door body 30 opening from the first angle G1 to the second angle G2. G =G1 or G G = G1 = 0°) to a second angle G2. In this process, the first central axis P moves away from the door front wall 31 and the door side wall 32; the second central axis Q moves away from the door front wall 31 and the door side wall 32.

[0198] Specifically, the first central axis P moves from the first guiding point P1 along the guiding trajectory line S to the second guiding point P2; the second central axis Q moves from the first guiding point Q1 along the guiding trajectory line K to the second guiding point Q2.

[0199] The first stage of opening process is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0200] The door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the second angle G2, the axis segment PQ rotates clockwise from P1Q1 to P2Q2; that is, the movement trend of the axis segment PQ is P1Q1 → P2Q2. Simultaneously, the axis center point I moves along the axis line segment PQ in a trend of I1 → I2. Specifically, during the opening of the door body 30, the axis center point I moves away from the door front wall 31 and the door side walls 32 relative to the door body 30.

[0201] Since the guide portion 50 and the guide portion 60 are provided on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 provided on the box body 10. It is concluded that: with the door body 30 as a reference, the door body 30 is moved from the first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the second angle G2, the box body 10 (i.e., the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and moves a certain distance to the side away from the door front wall 31 and the door side wall 32.

[0202] In summary, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G= G1 = 0°) to the second angle G2, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and also undergoes a translational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32, and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0203] According to the relativity of movement, with the box 10 as a reference, the door 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the second angle G2, the door body 30 undergoes a simultaneous translational motion while rotating. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 undergoes a displacement parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 33 and toward the door front wall 31.

[0204] like Figure 3-Figure 5 and Figure 13 As shown, under the constraints of the guide portion 50 and the first shaft 41, and the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a second stage. The second stage is as follows:

[0205] In some embodiments of the present application, the guide trajectory line S has a third guide point P3 and a fourth guide point P4 that are sequentially close to the door side wall 32 .

[0206] The second guiding point P2 , the third guiding point P3 , and the fourth guiding point P4 are sequentially close to the door side wall 32 .

[0207] The second guiding point P2, the third guiding point P3, and the fourth guiding point P4 are sequentially closer to the door front wall 31. That is, the distances between the second guiding point P2, the third guiding point P3, and the fourth guiding point P4 and the door front wall 31 decrease sequentially.

[0208] The guide track line S extends from the second guide point P2 to a side close to the door side wall 32 to a fourth guide point P4.

[0209] The guide track line S extends from the second guide point P2 to a side close to the door front wall 31 to a fourth guide point P4.

[0210] The guide trajectory line S extends from the second guide point P2 through the third guide point P3 to the fourth guide point P4.

[0211] In some embodiments of the present application, the fourth guiding point P4 is located on a side of the first guiding point P1 close to the door side wall 32 and the door front wall 31 .

[0212] In some embodiments of the present application, the guide trajectory line K has a third guide point Q3 and a fourth guide point Q4.

[0213] The second guide point Q2 , the third guide point Q3 , and the fourth guide point Q4 are sequentially away from the door side wall 32 .

[0214] The second guide point Q2, the third guide point Q3, and the fourth guide point Q4 are sequentially away from the door front wall 31. That is, the distances between the second guide point Q2, the third guide point Q3, and the fourth guide point Q4 and the door front wall 31 increase sequentially.

[0215] The guide track line K extends from the second guide point Q2 to a side away from the door side wall 32 to a fourth guide point Q4.

[0216] The guide track line K extends from the second guide point Q2 to a side away from the door front wall 31 to a fourth guide point Q4.

[0217] The guide trajectory line K extends from the second guide point Q2 through the third guide point Q3 to the fourth guide point Q4.

[0218] When the door body 30 is opened from the second angle G2 to the fourth angle G4 , the first central axis P moves toward the side close to the door front wall 31 and the door side wall 32 .

[0219] When the door body 30 opens from the second angle G2 to the fourth angle G4, the second central axis Q moves away from the door front wall 31 and the door side wall 32. The second angle G2 is smaller than the fourth angle G4.

[0220] When the door body 30 is opened from the second angle G2 to the fourth angle G4, the first central axis P moves from the second guiding point P2 to the fourth guiding point P4 via the third guiding point P3.

[0221] When the door body 30 opens from the second angle G2 to the fourth angle G4, the second central axis Q moves from the second guide point Q2 to the fourth guide point Q4 via the third guide point Q3.

[0222] In some embodiments of the present application, when the door body 30 opens from the second angle G2 to the third angle G3, the center point I of the axis moves from the second center point I2 to the side away from the door front wall 31 and the door side wall 32 to the third center point I3.

[0223] When the door body 30 opens from the third angle G3 to the fourth angle G4, the axis center point I moves from the third center point I3 to the side away from the door front wall 31 and close to the door side wall 32 to the fourth center point I4.

[0224] When the door body 30 is opened from the second angle G2 to the fourth angle G4, the axis center point I moves from the second center point I2 to the fourth center point I4 via the third center point I3.

[0225] When the door body 30 opens from the second angle G2 to the fourth angle G4, the center point I of the axis first moves away from the door front wall 31 and the door side wall 32, and then moves away from the door front wall 31 and closer to the door side wall 32.

[0226] In some embodiments of the present application, the second angle G2 is less than the third angle G3 and is less than the fourth angle G4.

[0227] During the second stage of opening, the door body 30 opens at an angle of When , the first central axis P is located at the second guide point P2 of the guide trajectory line S, the second central axis Q is located at the second guide point Q2 of the guide trajectory line K, and the midpoint of the axis is located at the second midpoint I2.

[0228] Door body 30 opening angle When , the first central axis P is located at the third guide point P3 of the guide trajectory line S, the second central axis Q is located at the third guide point Q3 of the guide trajectory line K, and the midpoint of the axis is located at the third midpoint I3.

[0229] Door body 30 opening angle When , the first central axis P is located at the fourth guide point P4 of the guide trajectory line S, the second central axis Q is located at the fourth guide point Q4 of the guide trajectory line K, and the midpoint of the axis is located at the fourth midpoint I4.

[0230] The second stage above describes the process of the door body 30 opening from the second angle G2 to the fourth angle G4. The door body 30 opens from the second angle G2 through G3 to G4. During this process, the first central axis P moves toward the side closer to the door front wall 31 and the door side walls 32. The second central axis Q moves away from the door front wall 31 and the door side walls 32.

[0231] Specifically, the first central axis P moves from the second guide point P2 along the guide trajectory S through the third guide point P3 to the fourth guide point P4. The second central axis Q moves from the second guide point Q2 along the guide trajectory K through the third guide point Q3 to the fourth guide point Q4.

[0232] The first stage of opening process is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0233] During the process of the door body 30 opening from the second angle G2 to the fourth angle G4, the axis line segment PQ rotates clockwise from P2Q2 and moves to P2Q2 and P4Q4 in sequence. That is, the movement trend of the axis line segment PQ is P2Q2→P3Q3→P4Q4. At the same time, the movement trend of the axis center point I as the axis line segment PQ moves is I2→I3→I4. During the process of the door body 30 opening from the second angle G2 to the fourth angle G4, relative to the door body 30, the axis center point I first moves away from the door front wall 31 and the door side wall 32, and then moves away from the door front wall 31 and closer to the door side wall 32.

[0234] Since the guide portion 50 and the guide portion 60 are provided on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 provided on the box body 10. It can be concluded that, with the door body 30 as a reference, during the entire process of the door body 30 opening from the second angle G2 to the fourth angle G4, the box body 10 (i.e., the hinge plate 40) continues to rotate clockwise relative to the door body 30, first moving a certain distance away from the door front wall 31 and the door side wall 32, and then moving a certain distance away from the door front wall 31 and closer to the door side wall 32.

[0235] In summary, when the door body 30 opens from the second angle G2 to the third angle G3, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and also undergoes a translational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32, and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0236] During the process of the door body 30 opening from the third angle G3 to the fourth angle G4, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and simultaneously undergoes a translational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 33 and away from the door front wall 31.

[0237] Due to the relativity of motion, with the cabinet 10 as a reference, when the door 30 opens from the second angle G2 to the third angle G3, the door 30 undergoes simultaneous translational motion while undergoing rotational motion. Specifically, the translational motion is as follows: relative to the door 30, the cabinet 10 undergoes displacement parallel to the door rear wall 33 and toward the door side wall 32, and displacement parallel to the door side wall 33 and toward the door front wall 31.

[0238] When the door 30 is opened from the third angle G3 to the fourth angle G4, the door 30 undergoes a simultaneous translational motion while undergoing a rotational motion. Specifically, the translational motion is as follows: relative to the door 30, the box body 10 undergoes a displacement parallel to the door rear wall 33 and directed away from the door side wall 32, and a displacement parallel to the door side wall 33 and directed toward the door front wall 31.

[0239] like Figure 5-Figure 6 and Figure 14 As shown, under the constraints of the guide portion 50 and the first shaft 41, and the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a third stage. The third stage is as follows:

[0240] In some embodiments of the present application, the guide trajectory line S has a fifth guide point P5.

[0241] The fourth guiding point P4 and the fifth guiding point P5 are close to the door side wall 32 in sequence.

[0242] The fourth guiding point P4 and the fifth guiding point P5 are successively closer to the door front wall 31. That is, the distances between the fourth guiding point P4 and the fifth guiding point P5 and the door front wall 31 are successively reduced.

[0243] The guide trajectory line S extends from the fourth guide point P4 to a side close to the door side wall 32 to a fifth guide point P5.

[0244] The guide track line S extends from the fourth guide point P4 to the side close to the door front wall 31 to the fifth guide point P5.

[0245] The guide trajectory line S extends from the fourth guide point P4 to a side close to the door side wall 3 and the door front wall 31 to a fifth guide point P5.

[0246] In some embodiments of the present application, there is a fifth guiding point Q5 on the guiding trajectory line K.

[0247] The fourth guide point Q4 and the fifth guide point Q5 are close to the door side wall 32 in sequence.

[0248] The fourth guide point Q4 and the fifth guide point Q5 are sequentially spaced away from the door front wall 31. That is, the distances between the fourth guide point Q4 and the fifth guide point Q5 and the door front wall 31 are sequentially increased.

[0249] The guide track line K extends from the fourth guide point Q4 to the side close to the door side wall 32 to the fifth guide point Q5.

[0250] The guide track line K extends from the fourth guide point Q4 to a side away from the door front wall 31 to a fifth guide point Q5.

[0251] The guide track line K extends from the fourth guide point Q4 to a side close to the door side wall 32 and the door front wall 31 to a fifth guide point Q5.

[0252] In some embodiments of the present application, the guide trajectory line S is a straight line, and the fifth guide point Q5 is located on the straight line where the guide trajectory line S is located. That is, the straight line where the fifth guide point P5 and the fifth guide point Q5 are located is collinear with the guide trajectory line S.

[0253] When the door body 30 is opened from the fourth angle G4 to the fifth angle G5 , the first central axis P moves toward the side close to the door front wall 31 and the door side wall 32 .

[0254] When the door body 30 opens from the fourth angle G4 to the fifth angle G5, the second central axis Q moves away from the door front wall 31 and closer to the door side wall 32. The fourth angle G4 is smaller than the fifth angle G5.

[0255] When the door body 30 is opened from the fourth angle G4 to the fifth angle G5, the first central axis P moves from the fourth guiding point P4 to the fifth guiding point P5.

[0256] When the door body 30 opens from the fourth angle G4 to the fifth angle G5, the second central axis Q moves from the fourth guide point Q4 to the fifth guide point Q5.

[0257] In some embodiments of the present application, the fourth angle G4 is smaller than the fifth angle G5.

[0258] In some embodiments of the present application, when the door body 30 opens from the fourth angle G4 to the fifth angle G5, the center point I of the axis moves from the fourth center point I4 to the side close to the door front wall 31 and the door side wall 32 to the fifth center point I5.

[0259] When the door body 30 opens from the fourth angle G4 to the fifth angle G5, the axis center point I moves from the fourth center point I4 to the fifth center point I5.

[0260] During the process of the door body 30 opening from the fourth angle G4 to the fifth angle G5 , the center point I of the axis moves away from the door front wall 31 and closer to the door side wall 32 .

[0261] During the third stage of opening, the door 30 opens at an angle of When , the first central axis P is located at the fourth guide point P4 of the guide trajectory line S, the second central axis Q is located at the fourth guide point Q4 of the guide trajectory line K, and the midpoint of the axis is located at the fourth midpoint I4.

[0262] Door body 30 opening angle When , the first central axis P is located at the fifth guide point P5 of the guide trajectory line S, the second central axis Q is located at the fifth guide point Q5 of the guide trajectory line K, and the midpoint of the axis is located at the fifth midpoint I5.

[0263] The third stage above describes the process of the door body 30 opening from the fourth angle G4 to the fifth angle G5. During this process, the first central axis P moves toward the side closer to the door front wall 31 and the door side walls 32, while the second central axis Q moves away from the door front wall 31 and toward the door side walls 32.

[0264] Specifically, the first central axis P moves from the fourth guide point P4 along the guide trajectory line S to the fifth guide point P5; the second central axis Q moves from the fourth guide point Q4 along the guide trajectory line K to the fifth guide point Q5.

[0265] The opening process in the third stage is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0266] As the door 30 opens from the fourth angle G4 to the fifth angle G5, the axis segment PQ rotates clockwise from P4Q4 to P5Q5; that is, the movement trend of the axis segment PQ is P4Q4 → P5Q5. Simultaneously, the axis center point I moves along the axis line from I4 to I5 as the axis segment PQ moves. Specifically, as the door 30 opens, the axis center point I moves away from the door front wall 31 and closer to the door side wall 32 relative to the door body 30.

[0267] Since the guide portion 50 and the guide portion 60 are provided on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 provided on the box body 10. Therefore, it can be concluded that, with the door body 30 as a reference, during the entire process of the door body 30 opening from the fourth angle G4 to the fifth angle G5, the box body 10 (i.e., the hinge plate 40) continues to rotate clockwise relative to the door body 30 and moves a certain distance toward the side away from the door front wall 31 and closer to the door side wall 32.

[0268] In summary, when the door body 30 opens from the fourth angle G4 to the fifth angle G5, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and also undergoes a translational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 33 and away from the door front wall 31.

[0269] According to the relativity of motion, with the cabinet 10 as a reference, when the door 30 opens from the fourth angle G4 to the fifth angle G5, the door 30 undergoes simultaneous translational motion while undergoing rotational motion. Specifically, the translational motion is as follows: relative to the door 30, the cabinet 10 undergoes displacement parallel to the door rear wall 33 and directed away from the door side wall 32, and displacement parallel to the door side wall 33 and directed toward the door front wall 31.

[0270] like Figure 6-Figure 7 and Figure 15As shown, under the constraints of the guide portion 50 and the first shaft 41, and the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a fourth stage. The fourth stage is as follows:

[0271] In some embodiments of the present application, the guide trajectory line S has a sixth guide point P6.

[0272] The fifth guiding point P5 and the sixth guiding point P6 are close to the door side wall 32 in sequence.

[0273] The guide trajectory line S extends from the fifth guide point P5 to a side away from the door side wall 32 to a sixth guide point P6.

[0274] The guide trajectory line S extends from the fifth guide point P5 to a side away from the door front wall 31 to a sixth guide point P6.

[0275] The guide trajectory line S extends from the fifth guide point P5 to a side away from the door side wall 32 and the door front wall 31 to a sixth guide point P6.

[0276] In some embodiments of the present application, the sixth guiding point P6 is located on a side of the second guiding point P2 close to the door side wall 32 .

[0277] Then, the fifth guiding point P5 , the sixth guiding point P6 , and the second guiding point P2 are sequentially away from the door side wall 32 .

[0278] In some embodiments of the present application, the sixth guiding point P6 is located on a side of the second guiding point P2 close to the door front wall 31 .

[0279] Then, the fifth guiding point P5, the sixth guiding point P6, and the second guiding point P2 are sequentially away from the door front wall 31. That is, the distances between the fifth guiding point P5, the sixth guiding point P6, and the second guiding point P2 and the door front wall 31 increase sequentially.

[0280] The guide trajectory line S extends from the fifth guide point P5 to a side away from the door side wall 32 to the second guide point P2.

[0281] The guide trajectory line S extends from the fifth guide point P5 to a side away from the door front wall 31 to the second guide point P2.

[0282] The guide trajectory line S extends from the fifth guide point P5 to the second guide point P2 via the sixth guide point P6.

[0283] In some embodiments of the present application, a sixth guide point Q6 is provided on the guide track line K. The fifth guide point Q5 and the sixth guide point Q6 are respectively close to the door side wall 32 .

[0284] Among them, the fourth guiding point Q4, the fifth guiding point Q5, and the sixth guiding point Q6 are close to the door side wall 32 in sequence.

[0285] The fifth guide point Q5 and the sixth guide point Q6 are successively farther away from the door front wall 31. That is, the distances between the fifth guide point Q5 and the sixth guide point Q6 and the door front wall 31 are successively increased.

[0286] The guide track line K extends from the fifth guide point Q5 to the side close to the door side wall 32 to the sixth guide point Q6.

[0287] The guide track line K extends from the fifth guide point Q5 to a side away from the door front wall 31 to a sixth guide point Q6.

[0288] The guide track line K extends from the fifth guide point Q5 to a sixth guide point Q6 toward a side close to the door side wall 32 and away from the door front wall 31 .

[0289] When the door body 30 is opened from the fifth angle G5 to the sixth angle G6 , the first central axis P moves toward a side away from the door front wall 31 and the door side wall 32 .

[0290] When the door body 30 opens from the fifth angle G5 to the sixth angle G6, the second central axis Q moves away from the door front wall 31 and closer to the door side wall 32. The fifth angle G5 is smaller than the sixth angle G6.

[0291] When the door body 30 is opened from the fifth angle G5 to the sixth angle G6, the first central axis P moves from the fifth guiding point P5 to the sixth guiding point P6.

[0292] When the door body 30 opens from the fifth angle G5 to the sixth angle G6, the second central axis Q moves from the fifth guide point Q5 to the sixth guide point Q6.

[0293] In some embodiments of the present application, when the door body 30 opens from the fifth angle G5 to the sixth angle G6, the axial center point I moves from the fifth center point I5 to the side away from the door front wall 31 and close to the door side wall 32 to the sixth center point I6.

[0294] During the process of the door body 30 opening from the fifth angle G5 to the sixth angle G6 , the center point I of the axis moves away from the door front wall 31 and closer to the door side wall 32 .

[0295] During the fourth stage of opening, the door 30 opens at an angle of When , the first central axis P is located at the fifth guide point P5 of the guide trajectory line S, the second central axis Q is located at the fifth guide point Q5 of the guide trajectory line K, and the midpoint of the axis is located at the fifth midpoint I5.

[0296] Door body 30 opening angle When , the first central axis P is located at the sixth guide point P6 of the guide trajectory line S, the second central axis Q is located at the sixth guide point Q6 of the guide trajectory line K, and the midpoint of the axis is located at the sixth midpoint I6.

[0297] The fourth stage above describes the process of the door body 30 opening from the fifth angle G5 to the sixth angle G6. During this process, the first central axis P moves away from the door front wall 31 and the door side walls 32. The second central axis Q moves away from the door front wall 31 and toward the door side walls 32.

[0298] Specifically, when the door body 30 opens from the fifth angle G5 to the sixth angle G6, the first central axis P moves from the fifth guide point P5 to the sixth guide point P6 along the guide trajectory S. The second central axis Q moves from the fifth guide point Q5 to the sixth guide point Q6 along the guide trajectory K.

[0299] The opening process in the fourth stage is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0300] As the door 30 opens from the fifth angle G5 to the sixth angle G6, the axis segment PQ rotates clockwise from P5Q5 to P6Q6; that is, the movement trend of the axis segment PQ is P5Q5 → P6Q6. Simultaneously, the axis center point I moves along the axis line from I5 to I6 as the axis segment PQ moves. Specifically, as the door 30 opens, the axis center point I moves away from the door front wall 31 and closer to the door side wall 32 relative to the door body 30.

[0301] Since the guide portion 50 and the guide portion 60 are provided on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 provided on the box body 10. Therefore, it can be concluded that, with the door body 30 as a reference, during the entire process of the door body 30 opening from the fifth angle G5 to the sixth angle G6, the box body 10 (i.e., the hinge plate 40) continues to rotate clockwise relative to the door body 30 and moves a certain distance toward the side away from the door front wall 31 and closer to the door side wall 32.

[0302] In summary, when the door body 30 opens from the fifth angle G5 to the sixth angle G6, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and simultaneously undergoes a translational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 33 and away from the door front wall 31.

[0303] According to the relativity of motion, with the cabinet 10 as a reference, when the door 30 opens from the fifth angle G5 to the sixth angle G6, the door 30 undergoes simultaneous rotational motion. Specifically, the translational motion is as follows: relative to the door 30, the cabinet 10 undergoes displacement parallel to the door rear wall 33 and directed away from the door side wall 32, and displacement parallel to the door side wall 33 and directed toward the door front wall 31.

[0304] like Figure 7-10 and Figure 16 As shown, under the constraints of the guide portion 50 and the first shaft 41, and the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a fifth stage. The fifth stage is as follows:

[0305] In some embodiments of the present application, the guide trajectory line S has a seventh guide point P7 , an eighth guide point P8 , and a ninth guide point P9 , which are sequentially close to the door side wall 32 .

[0306] The sixth guiding point P6, the seventh guiding point P7, the eighth guiding point P8 and the ninth guiding point P9 are sequentially close to the door side wall 32. The sixth guiding point P6, the seventh guiding point P7, the eighth guiding point P8 and the ninth guiding point P9 are sequentially close to the door front wall 31.

[0307] According to the relative position relationship between the second guiding point P2 and the sixth guiding point P6 , the second guiding point P2 , the sixth guiding point P6 , the seventh guiding point P7 , the eighth guiding point P8 , and the ninth guiding point P9 are sequentially close to the door side wall 32 .

[0308] The second guiding point P2, the sixth guiding point P6, the seventh guiding point P7, the eighth guiding point P8, and the ninth guiding point P9 are successively closer to the door front wall 31. That is, the distances between the second guiding point P2, the sixth guiding point P6, the seventh guiding point P7, the eighth guiding point P8, and the ninth guiding point P9 and the door front wall 31 decrease successively.

[0309] The guide trajectory line S extends from the sixth guide point P6 to a side close to the door side wall 32 to a ninth guide point P9.

[0310] The guide trajectory line S extends from the sixth guide point P6 to a side close to the door front wall 31 to a ninth guide point P9.

[0311] The guide trajectory line S extends from the sixth guide point P6 to the seventh guide point P7 and the eighth guide point P8 to the ninth guide point P9.

[0312] In some embodiments of the present application, the guide track line K has a seventh guide point Q7, an eighth guide point Q8, and a ninth guide point Q9 which are sequentially close to the door side wall 32.

[0313] Among them, the sixth guide point Q6, the seventh guide point Q7, the eighth guide point Q8, and the ninth guide point Q9 are close to the door side wall 32 in sequence.

[0314] The sixth guide point Q6, the seventh guide point Q7, the eighth guide point Q8, and the ninth guide point Q9 are sequentially farther away from the door front wall 31. That is, the distances between the sixth guide point Q6, the seventh guide point Q7, the eighth guide point Q8, and the ninth guide point Q9 and the door front wall 31 increase sequentially.

[0315] The guide track line K extends from the sixth guide point Q6 to the side close to the door side wall 32 to the ninth guide point Q9.

[0316] The guide track line K extends from the sixth guide point Q6 to a side away from the door front wall 31 to a ninth guide point Q9.

[0317] The guide trajectory line K extends from the sixth guide point Q6 through the seventh guide point Q7 and the eighth guide point Q8 to the ninth guide point Q9.

[0318] According to the relative position relationship of the aforementioned guide points, the fourth guide point Q4, the fifth guide point Q5, the sixth guide point Q6, the seventh guide point Q7, the eighth guide point Q8, and the ninth guide point Q9 are close to the door side wall 32 in sequence.

[0319] The fourth guide point Q4 , the fifth guide point Q5 , the sixth guide point Q6 , the seventh guide point Q7 , the eighth guide point Q8 , and the ninth guide point Q9 are sequentially away from the door front wall 31 .

[0320] When the door body 30 opens from the sixth angle G6 to the ninth angle G9 , the first central axis P moves toward a side close to the door front wall 31 and the door side wall 32 .

[0321] When the door body 30 opens from the sixth angle G6 to the ninth angle G9, the second central axis Q moves away from the door front wall 31 and closer to the door side wall 32. The sixth angle G6 is smaller than the ninth angle G9.

[0322] When the door body 30 opens from the sixth angle G6 to the ninth angle G9, the first central axis P moves from the sixth guiding point P6 to the ninth guiding point P9 via the seventh guiding point P7 and the eighth guiding point P8 in sequence.

[0323] When the door body 30 opens from the sixth angle G6 to the ninth angle G9, the second central axis Q moves from the sixth guide point Q6 to the ninth guide point Q9 via the seventh guide point Q7 and the eighth guide point P8.

[0324] In some embodiments of the present application, when the door body 30 opens from the sixth angle G6 to the eighth angle G8, the axis center point I moves from the sixth center point I6 to the side away from the door front wall 31 and closer to the door side wall 32 to the eighth center point I8. The sixth angle G6 is less than the eighth angle G8.

[0325] When the door body 30 opens from the eighth angle G8 to the ninth angle G9, the axis center I moves from the eighth center point I8 to the side close to the door front wall 31 and the door side wall 32 to the ninth center point I9.

[0326] During the process of the door body 30 opening from the sixth angle G6 to the ninth angle G9, the axis center point I moves from the sixth center point I6 to the ninth center point I9 via the seventh center point I7 and the eighth center point I8 in sequence.

[0327] When the door body 30 opens from the sixth angle G6 to the ninth angle G9, the center point I of the axis first moves away from the door front wall 31 and close to the door side wall 32, and then moves close to the door front wall 31 and the door side wall 32.

[0328] Among them, the sixth angle G6 is less than the seventh angle G7 and the eighth angle G8 is less than the ninth angle G9.

[0329] During the fifth stage of opening, the door 30 opens at an angle of When , the first central axis P is located at the sixth guide point P6 of the guide trajectory line S, the second central axis Q is located at the sixth guide point Q6 of the guide trajectory line K, and the midpoint of the axis is located at the sixth midpoint I6.

[0330] Door body 30 opening angle When , the first central axis P is located at the seventh guide point P7 of the guide trajectory line S, the second central axis Q is located at the seventh guide point Q7 of the guide trajectory line K, and the midpoint of the axis is located at the seventh midpoint I7.

[0332] Door body 30 opening angle When , the first central axis P is located at the ninth guide point P9 of the guide trajectory line S, the second central axis Q is located at the ninth guide point Q9 of the guide trajectory line K, and the midpoint of the axis is located at the ninth midpoint I9.

[0333] In some embodiments of the present application, G7=90°.

[0334] In some embodiments of the present application, when the door body 30 is opened to 90°, the door front wall 31 is located on the side of the first body side wall close to the second body side wall, and the distance between the door front wall 31 and the first body side wall is not less than 4 mm.

[0335] The fifth stage above describes the process of the door body 30 opening from the sixth angle G6 to the ninth angle G9. The door body 30 opens from the sixth angle G6 through angles G7, G8, and finally G9. During this process, the first central axis P moves toward the side closer to the door front wall 31 and the door side walls 32, while the second central axis Q moves away from the door front wall 31 and toward the door side walls 32.

[0336] Specifically, when the door body 30 opens from the sixth angle G6 to the ninth angle G9, the first central axis P moves from the sixth guide point P6 along the guide trajectory S, sequentially passing through the seventh guide point P7 and the eighth guide point P8, to the ninth guide point P9. The second central axis Q moves from the sixth guide point Q6 along the guide trajectory K, sequentially passing through the seventh guide point Q7 and the eighth guide point Q8, to the ninth guide point Q9.

[0337] The opening process in the fifth stage is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0338] As the door 30 opens from the sixth angle G6 to the ninth angle G9, the axis line segment PQ rotates clockwise from P6Q6 and moves to P7Q7, P8Q8, and P9Q9, respectively; that is, the movement trend of the axis line segment PQ is P6Q6 → P7Q7 → P8Q8 → P9Q9. Simultaneously, the movement trend of the axis center point I as the axis line segment PQ moves is I6 → I7 → I8 → I9. That is, as the door 30 opens, the axis center point I first moves away from the door front wall 31 and closer to the door side walls 32, and then moves closer to the door front wall 31 and door side walls 32.

[0339] Since the guide portion 50 and the guide portion 60 are provided on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 provided on the box body 10. It can be concluded that, taking the door body 30 as a reference, during the entire process of the door body 30 opening from the sixth angle G6 to the ninth angle G9, the box body 10 (i.e., the hinge plate 40) continues to rotate clockwise relative to the door body 30, first moving a certain distance away from the door front wall 31 and closer to the door side wall 32, and then moving a certain distance closer to the door front wall 31 and the door side wall 32.

[0340] In summary, when the door body 30 opens from the sixth angle G6 to the eighth angle G8, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and simultaneously undergoes a translational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 33 and away from the door front wall 31.

[0341] During the process of the door body 30 opening from the eighth angle G8 to the ninth angle G9, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and simultaneously undergoes a translational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 undergoes a displacement parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 33 and toward the door front wall 31.

[0342] According to the relativity of motion, with the cabinet 10 as a reference, when the door 30 opens from the sixth angle G6 to the eighth angle G8, the door 30 undergoes simultaneous rotational motion. Specifically, the translational motion is as follows: relative to the door 30, the cabinet 10 undergoes displacement parallel to the door rear wall 33 and directed away from the door side walls 32, and displacement parallel to the door side walls 33 and directed toward the door front wall 31.

[0343] When the door body 30 is opened from the eighth angle G8 to the ninth angle G9, the door body 30 undergoes a translational motion while rotating. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 undergoes a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32, and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0344] like Figure 10-11 and Figure 17 As shown, under the constraints of the guide portion 50 and the first shaft 41, and the guide portion 60 and the second shaft 42, the opening process of the door body 30 has a sixth stage. The sixth stage is as follows:

[0345] In some embodiments of the present application, the guide trajectory line S has a tenth guide point P 10 .

[0346] Among them, the ninth guiding point P9 and the tenth guiding point P 10 The ninth guiding point P9 and the tenth guiding point P 10 Approach the door front wall 31 in turn.

[0347] The guide track line S extends from the ninth guide point P9 to the side close to the door side wall 32 to the tenth guide point P 10 .

[0348] The guide track line S extends from the ninth guide point P9 to the side close to the door front wall 31 to the tenth guide point P 10 .

[0349] According to the relative position relationship of the second guide point P2, the sixth guide point P6, the seventh guide point P7, the eighth guide point P8, and the ninth guide point P9, the second guide point P2, the sixth guide point P6, the seventh guide point P7, the eighth guide point P8, the ninth guide point P9, and the tenth guide point P 10 Close to the door side wall 32 in turn.

[0353] The guidance trajectory line S extends from the second guidance point P2 through the sixth guidance point P6, the seventh guidance point P7, the eighth guidance point P8, the ninth guidance point P9 to the tenth guidance point P 10 .

[0354] In some embodiments of the present application, the ninth guiding point P9 is located on a side of the fifth guiding point P5 close to the door side wall 32 .

[0355] The ninth guiding point P9 is located on a side of the fifth guiding point P5 close to the door front wall 31 .

[0356] The eighth guiding point P8 is located on a side of the fifth guiding point P5 away from the door side wall 32 .

[0357] The eighth guiding point P8 is located on a side of the fifth guiding point P5 away from the door front wall 31 .

[0358] Then, the guidance trajectory line S extends from the second guidance point P2 through the sixth guidance point P7, the seventh guidance point P7, the eighth guidance point P8, the fifth guidance point P5, the ninth guidance point P9 to the tenth guidance point P 10 .

[0359] In some embodiments of the present application, the guide track line K has a tenth guide point Q close to the door side wall 32. 10 .

[0360] Among them, the ninth guiding point Q9 and the tenth guiding point Q 10 Close to the door side wall 32 in turn.

[0361] Ninth guiding point Q9, tenth guiding point Q 10 The ninth guide point Q9 and the tenth guide point Q 10 The distances between each door and the door front wall 31 decrease successively.

[0362] The guide track line K extends from the ninth guide point Q9 to the side close to the door side wall 32 to the tenth guide point Q 10 .

[0363] The guide track line K extends from the ninth guide point Q9 to the side close to the door front wall 31 to the tenth guide point Q 10 .

[0364] According to the relative position relationship of the aforementioned guide points, the ninth guide point Q9 is the point on the guide trajectory line K that is the farthest away from the door front wall 31 .

[0365] The door body 30 opens from the ninth angle G9 to the tenth angle G 10 During the process, the first central axis P moves toward the side close to the door front wall 31 and the door side wall 32.

[0366] The door body 30 opens from the ninth angle G9 to the tenth angle G 10 During the process, the second central axis Q moves toward the side close to the door front wall 31 and the door side wall 32. 10 .

[0367] The door body 30 opens from the ninth angle G9 to the tenth angle G 10 During the process, the first central axis P moves from the ninth guide point Q9 to the tenth guide point P 10 .

[0368] The door body 30 opens from the ninth angle G9 to the tenth angle G 10 During the process, the second central axis Q moves from the ninth guide point Q9 to the tenth guide point Q 10 .

[0369] In some embodiments of the present application, the door body 30 is opened from the ninth angle G9 to the tenth angle G 10 During the process, the axis center point I moves from the ninth center point I9 to the side close to the door front wall 31 and the door side wall 32 to the tenth center point I 10 .

[0370] The door body 30 opens from the ninth angle G9 to the tenth angle G 10 During the process, the center point I of the axis moves toward the side close to the door front wall 31 and the door side wall 32.

[0371] During the sixth stage of opening, the door 30 opens at an angle of When , the first central axis P is located at the ninth guide point P9 of the guide trajectory line S, the second central axis Q is located at the ninth guide point Q9 of the guide trajectory line K, and the midpoint of the axis is located at the ninth midpoint I9.

[0372] Door body 30 opening angle When the first central axis P is located at the tenth guiding point P of the guiding trajectory line S 10 The second center axis Q is located at the tenth guide point Q of the guide trajectory line K 10 , the center point of the axis is located at the tenth midpoint I 10 .

[0373] The sixth stage is when the door 30 opens from the ninth angle G9 to the tenth angle G 10 During this process, the first central axis P moves toward the side close to the door front wall 31 and the door side wall 32. The second central axis Q moves toward the side close to the door front wall 31 and the door side wall 32.

[0374] Specifically, the door body 30 is opened from the ninth angle G9 to the tenth angle G 10 During the process, the first central axis P moves from the ninth guiding point P9 along the guiding trajectory line S to the tenth guiding point P 10 The second center axis Q moves from the ninth guide point Q9 along the guide trajectory line K to the tenth guide point Q 10 .

[0375] The sixth stage of opening is described with reference to the second hinge member (the guide portion 50 / the guide portion 60 / the door body 30 ).

[0376] The door body 30 opens from the ninth angle G9 to the tenth angle G 10 In the process, the axis line segment PQ rotates clockwise from P9Q9 to P 10 Q 10 That is, the movement trend of the axis segment PQ is P9Q9→P 10 Q 10 At the same time, the movement trend of the axis center point I along the axis line segment PQ is I9→I 10 That is, during the opening process of the door body 30 , the center point I of the axis moves toward the side close to the door front wall 31 and the door side wall 32 relative to the door body 30 .

[0377] Since the guide portion 50 and the guide portion 60 are provided on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 provided on the box body 10. It is concluded that: with the door body 30 as a reference, the door body 30 opens from the ninth angle G9 to the tenth angle G 10 During the whole process, the box body 10 (ie, the hinge plate 40) keeps rotating clockwise relative to the door body 30 to open, and moves a certain distance toward the side close to the door front wall 31 and the door side wall 32.

[0378] In summary, the door body 30 is opened from the ninth angle G9 to the tenth angle G 10 During the process, with the door body 30 (guide groove / guide slot) as a reference, the box body 10 performs a rotational motion relative to the door body 30 and also undergoes a translational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 33 and toward the door front wall 31.

[0379] According to the relativity of movement, with the box 10 as a reference, the door 30 opens from the ninth angle G9 to the tenth angle G10 During the process, the door body 30 has a translational motion while performing a rotational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32, and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0380] In some embodiments of the present application, the first guide point P1, the second guide point P2, the third guide point P3, the fourth guide point P4, the fifth guide point P5, the sixth guide point P6, the seventh guide point P7, the eighth guide point P8, the ninth guide point P9, the tenth guide point P 10 Located on the guide trajectory line S.

[0381] Along the direction from the door rear wall 33 to the door front wall 31 , the distance between the guide track line S and the door side wall 32 gradually decreases.

[0382] In some embodiments of the present application, the guide trajectory line S is a straight line.

[0383] The angle between the guide trajectory line S and the front wall of the door is denoted as γ;

[0384] Wherein, γ is not less than a first angle reference value; the first angle reference value is between 23° and 29°. The first angle reference value can be 23°, 26°, or 29°. That is, γ ≥ 23°, γ ≥ 26°, or γ ≥ 29°.

[0385] When γ ≥ 23°, the fixing space requirement for the mounting block and the requirement that the thickness of the door body 30 is small are met. When γ ≥ 26°, the fixing space requirement for the mounting block and the requirement that the thickness of the door body 30 is small are better met. When γ ≥ 29°, the fixing space requirement for the mounting block and the requirement that the thickness of the door body 30 is small are even better met.

[0386] γ is not greater than a second angle reference value; the second angle reference value is between 31° and 37°. The second angle reference value can be 31°, 34°, or 37°. That is, γ≤31°, γ≤34°, or γ≤37°.

[0387] When γ≤31°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When γ≤34°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When γ≤37°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is met.

[0388] If γ is too large, the wall thickness between the guide portion 50 and the guide portion 60 will be too thin, reducing the strength of the guide portion 50 and the guide portion 60. In addition, when the distance between the end of the guide portion 50 away from the door side wall 31 and the door front wall 31 is relatively large, the size of the guide portion 60 in the direction perpendicular to the door front wall 31 increases simultaneously, and the size of the overall trajectory of the guide portion 50 and the guide portion 60 in the direction perpendicular to the door front wall 31 becomes larger, resulting in an increase in the thickness of the door body 30, affecting its use in ultra-thin refrigerators. Furthermore, the excessive thickness of the door body 30 increases the obstruction of the door body 30 to the access opening; and in order to ensure that the drawer installed in the storage room can be pulled out, the horizontal width of the drawer needs to be reduced, resulting in the drawer not being able to effectively utilize the horizontal space of the storage room.

[0389] If γ is too small, there will be insufficient space on the mounting block for screws (not limited to screw fixing, any conventional fixing method that can fix two parts together) between the two tracks of the guide portion 50 and the guide portion 60. In order to meet the fixing requirements, the area of the mounting block needs to be increased; and in order to ensure the fixing strength of the mounting block, it is particularly necessary to increase the size of the mounting block in the direction perpendicular to the door front wall 31 to increase the position for screws (not limited to screw fixing, any conventional fixing method that can fix two parts together). The increase in the size of the mounting block in the direction perpendicular to the door front wall 31 will increase the thickness of the door body 30 that is adapted thereto, affecting its use on ultra-thin refrigerators. Furthermore, if the thickness of the door body 30 is too large, the door body 30 will increase the obstruction of the access opening; and in order to ensure that the drawer installed in the storage room can be pulled out, the horizontal width of the drawer needs to be reduced, resulting in the drawer not being able to effectively utilize the horizontal space of the storage room.

[0390] In some embodiments of the present application, when the guide trajectory line S is a straight line, the fifth guide point Q5 is located on an extension line of the guide trajectory line S. That is, the fifth guide point Q5 is located on the straight line where the guide trajectory line S is located.

[0391] In some embodiments of the present application, the guide track line S is a curve and bulges toward the side close to the second side edge N.

[0392] In some embodiments of the present application, the door body 30 is opened from the first angle G1 to the tenth angle G 10 During the opening process, when the door body 30 is opened to the second angle G2, the first central axis P is located at the second guide point P2 of the guide trajectory S. On the guide trajectory S, the distance between the second guide point P2 and the door side wall 32 is the largest. On the guide trajectory S, the distance between the second guide point P2 and the door front wall 31 is the largest.

[0393] The second guiding point P2 and the tenth guiding point P 10 The straight line is recorded as straight line P2P 10 ; Straight Line P2P 10The angle between the door and the front wall is denoted as λ;

[0394] Wherein, λ is not less than a first reference angle value; the first reference angle value is between 23° and 29°. The first reference angle value can be 23°, 26°, or 29°. That is, λ ≥ 23°, λ ≥ 26°, or λ ≥ 29°.

[0395] When λ ≥ 23°, the fixing space requirement for the mounting block and the requirement that the thickness of the door body 30 is small are met. When λ ≥ 26°, the fixing space requirement for the mounting block and the requirement that the thickness of the door body 30 is small are better met. When λ ≥ 29°, the fixing space requirement for the mounting block and the requirement that the thickness of the door body 30 is small are even better met.

[0396] λ is not greater than a second reference angle value; the second reference angle value is between 31° and 37°. The first reference angle value can be 31°, 34°, or 37°. That is, λ≤31°, λ≤34°, or λ≤37°.

[0397] When λ≤31°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When λ≤34°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When λ≤37°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is met.

[0398] If λ is too large, the wall thickness between the guide portion 50 and the guide portion 60 will be too thin, reducing the strength of the guide portion 50 and the guide portion 60. In addition, when the distance between the end of the guide portion 50 away from the door side wall 31 and the door front wall 31 is relatively large, the size of the guide portion 60 in the direction perpendicular to the door front wall 31 increases simultaneously, and the size of the overall trajectory of the guide portion 50 and the guide portion 60 in the direction perpendicular to the door front wall 31 becomes larger, resulting in an increase in the thickness of the door body 30, affecting its use in ultra-thin refrigerators. Furthermore, the excessive thickness of the door body 30 increases the obstruction of the door body 30 to the access opening; and in order to ensure that the drawer installed in the storage chamber can be pulled out, the horizontal width of the drawer needs to be reduced, resulting in the drawer not being able to effectively utilize the horizontal space of the storage chamber.

[0399] If λ is too small, there will be insufficient space on the mounting block for screws (not limited to screw fixing, any conventional fixing method that can fix two components together) between the two tracks of the guide portion 50 and the guide portion 60. In order to meet the fixing requirements, the area of the mounting block needs to be increased; and in order to ensure the fixing strength of the mounting block, it is particularly necessary to increase the size of the mounting block in the direction perpendicular to the door front wall 31 to increase the position for screws (not limited to screw fixing, any conventional fixing method that can fix two components together). The increase in the size of the mounting block in the direction perpendicular to the door front wall 31 will increase the thickness of the door body 30 that is adapted thereto, affecting its use on ultra-thin refrigerators. Furthermore, if the thickness of the door body 30 is too large, the door body 30 will increase the obstruction of the access opening by the door body 30; and in order to ensure that the drawer installed in the storage room can be pulled out, the horizontal width of the drawer needs to be reduced, resulting in the drawer not being able to effectively utilize the horizontal space of the storage room.

[0400] In some embodiments of the present application, the door body 30 is opened from the first angle G1 to the tenth angle G 10 During the process, the door body 30 is opened to the tenth angle G 10 When the first central axis P is located at the tenth guiding point P of the guiding trajectory line S 10 On the guidance trajectory line S, the tenth guidance point P 10 The distance from the door side wall 32 is the smallest. On the guide trajectory line S, the tenth guide point P 10 The distance from the door front wall 31 is the smallest.

[0401] In some embodiments of the present application, the guide trajectory line S extends from the second guide point P2 to the side close to the door side wall 32 to the tenth guide point P 10 .

[0402] The guide track line S extends from the second guide point P2 to the side close to the door front wall 31 to the tenth guide point P 10 .

[0403] The first guide point P1, the third guide point P3, the fourth guide point P4, the fifth guide point P5, the sixth guide point P6, the seventh guide point P7, the eighth guide point P8, and the ninth guide point P9 are located on the guide trajectory line S and are located between the second guide point P2 and the tenth guide point P 10 between.

[0404] In some embodiments of the present application, the first angle G1 is less than the second angle G2 and the third angle G3 is less than the fourth angle G4 and the fifth angle G5 is less than the sixth angle G6 and the seventh angle G7 is less than 90° and the eighth angle G8 is less than the ninth angle G9 and the tenth angle G 10 .

[0405] In some embodiments of the present application, the first guiding point Q1, the second guiding point Q2, the third guiding point Q3, the fourth guiding point Q4, the fifth guiding point Q5, the sixth guiding point Q6, the seventh guiding point Q7, the eighth guiding point Q8, the ninth guiding point Q9, the tenth guiding point Q 10 Located on the guide trajectory line K.

[0406] In some embodiments of the present application, the guide track line K extends from the first guide point Q1 to the side away from the door side wall 32 to the fourth guide point Q4; then extends from the fourth guide point Q4 to the side close to the door side wall 32 to the tenth guide point Q 10 .

[0407] The guide track line K extends from the first guide point Q1 to the side away from the door front wall 31 to the ninth guide point Q9, and then extends from the ninth guide point Q9 to the side close to the door front wall 31 to the tenth guide point Q 10 .

[0408] The guide trajectory line K extends from the first guide point Q1 through the second guide point Q2, the third guide point Q3, the fourth guide point Q4, the fifth guide point Q5, the sixth guide point Q6, the seventh guide point Q7, the eighth guide point Q8, the ninth guide point Q9 to the tenth guide point Q 10 .

[0409] In some embodiments of the present application, the guide trajectory line K first extends from the first guide point Q1 to the side away from the door side wall 32 and the door side wall 32 to the fourth guide point Q4; then extends from the fourth guide point Q4 to the side away from the door front wall 31 and close to the door side wall 32 to the ninth guide point Q9, and then extends from the ninth guide point Q9 to the side close to the door front wall 31 and the door side wall 32 to the tenth guide point Q 10 .

[0410] The ninth guide point Q9 is the point where the distance between the guide trajectory line K and the door front wall 31 is the largest.

[0411] The fourth guide point Q4 is the point where the distance between the guide trajectory line K and the door side wall 32 is the largest.

[0412] In some embodiments of the present application, the first guide point P1 is located on the side of the first guide point Q1 close to the door rear wall 33 and the door side wall 32. The ninth guide point P9 is located on the side of the ninth guide point Q9 close to the door front wall 31 and the door side wall 32. The tenth guide point P 10 Located at the tenth guide point Q 10 The side close to the door front wall 31 and away from the door side wall 32.

[0413] Combining the first stage, the second stage, the third stage, the fourth stage, the fifth stage and the sixth stage, it can be seen that the door body 30 is opened from the first angle G1 to the tenth angle G 10During the opening process, the first shaft 41 first moves in the direction away from the door front wall 31 and the door side wall 32 (G1 to G2), then moves in the opposite direction toward the door front wall 31 and the door side wall 32 (G2 to G5), then moves in the opposite direction away from the door front wall 31 and the door side wall 32 (G5 to G6), and then moves in the opposite direction toward the door front wall 31 and the door side wall 32 (G6 to G7). 10 ). In summary, the door body 30 is opened from the first angle G1 to the tenth angle G 10 During the opening process, the first axis 41 turns three times relative to the movement direction of the door body 30. The hinge assembly with the above trajectory characteristics reduces the size of the guide portion 50 and fully utilizes the small-sized guide portion 50 to complete the opening of the door body 30 at a large angle.

[0414] Combining the situations of the first, second, third, fourth, fifth and sixth stages, we can see that: according to the relativity of motion, with the box body 10 as a reference, the door body 30 has a translational motion while rotating. The translational displacement component of the translational motion includes a displacement component parallel to the door rear wall 33 and a displacement component parallel to the door side wall 32. Among them, the displacement component parallel to the door rear wall 33 is recorded as the first direction displacement. The displacement component parallel to the door side wall 32 is the second displacement direction At different opening stages of the door body 30, the first direction displacement and the second direction displacement The direction will be different.

[0415] In summary, the movement process of the first central axis P and the second central axis Q of the door body 30 from the first stage to the sixth stage, and the movement trend of the synchronous axis center point I, can be used to understand the movement process of the axis center point I.

[0416] Specifically, such as Figure 18 As shown, the movement process of the axis center point I relative to the door body 30 includes a first axis trajectory segment.

[0417] First axis trajectory segment: when the door body 30 opens from the first angle G1 to the third angle G3 , the axis center point I moves toward the side away from the door front wall 31 and the door side wall 32 .

[0418] The axis center point I moves from the first center point I1 to the side away from the door front wall 31 and the door side wall 32 through the second center point I2 to the third center point I3.

[0419] Taking the box body 10 as a reference, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G= G1 = 0°) to the third angle G3, the door body 30 undergoes a simultaneous translational motion while rotating. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 undergoes a displacement parallel to the door rear wall 33 and toward the door side wall 32, and a displacement parallel to the door side wall 33 and toward the door front wall 31.

[0420] The door body 30 is formed by a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the third angle G3, the first direction displacement Pointing to the side of the door side wall 32, the second direction displacement Pointing to the side of the front wall 31 of the door.

[0421] like Figure 18 As shown, the movement process of the axis center point I relative to the door body 30 includes a second axis trajectory segment.

[0422] Second axis trajectory segment: when the door body 30 opens from the third angle G3 to the eighth angle G8, the axis center point I moves away from the door front wall 31 and closer to the door side wall 32.

[0423] The axis center point I moves from the third center point I3 to the side away from the door front wall 31 and close to the door side wall 32, passing through the fourth center point I4, the fifth center point I5, the sixth center point I6, the seventh center point I7 and the eighth center point I8.

[0424] Taking the cabinet 10 as a reference, as the door 30 opens from the third angle G3 to the eighth angle G8, the door 30 undergoes simultaneous rotational motion. Specifically, the cabinet 10 moves parallel to the door rear wall 33 and away from the door side walls 32, and parallel to the door side walls 33 and toward the door front wall 31.

[0425] During the process of the door body 30 opening from the third angle G3 to the eighth angle G8, the first direction displacement Pointing away from the door side wall 32, the second direction displacement Pointing to the side of the door front wall 31.

[0426] In some embodiments of the present application, the difference between the eighth angle G8 and 90° is recorded as ΔG8;

[0427] ΔG8 is not less than a first reference difference; the first reference difference is between 0° and 2°. The first reference difference can be 0°, 1°, or 2°. That is, ΔG8 ≥ 0°, ΔG8 ≥ 1°, or ΔG8 ≥ 2°.

[0428] When ΔG8 ≥ 0°, the door body 30 meets the requirement of shielding the access opening. When ΔG8 ≥ 1°, the door body 30 better meets the requirement of shielding the access opening. When ΔG8 ≥ 2°, the door body 30 better meets the requirement of shielding the access opening.

[0429] ΔG8 is not greater than a second reference difference; the second reference difference is between 3° and 6°. The second reference difference can be 3°, 4°, or 6°. That is, ΔG8 ≤ 3°, ΔG8 ≤ 4°, or ΔG8 ≤ 6°.

[0430] When ΔG8 ≤ 3°, the maximum opening angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 is better met. When ΔG8 ≤ 4°, the maximum opening angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 is better met. When ΔG8 ≤ 6°, the maximum opening angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 is met.

[0431] Among them, ΔG8 is too small, and after the door body 30 is opened to 90°, the outward displacement is too small, and the door body 30 blocks a large amount of the access opening, making it inconvenient for users to take and place items.

[0432] ΔG8 is too large. After the door body 30 is opened to 90°, the outward displacement is too large. The distance between the door body 30 and the storage cabinet 100 is too close. The maximum angle that the door body 30 of the refrigerator placed in the storage cabinet 100 can be opened is reduced, which is not conducive to the door body 30 being opened to a larger angle. It is especially inconvenient for users to take and place items placed inside the door body 30.

[0433] like Figure 18 As shown, the movement process of the axis center point I relative to the door body 30 includes a third axis trajectory segment.

[0434] The third axis track segment: the door body 30 opens from the eighth angle G8 to the tenth angle G 10 During the process, the center point I of the axis moves toward the side close to the door front wall 31 and the door side wall 32.

[0435] The axis center point I moves from the eighth center point I8 to the side close to the door front wall 31 and the door side wall 32 through the ninth center point I9 to the tenth center point I 10 .

[0436] Taking the box body 10 as a reference, the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 During the process, the door body 30 has a translational motion while performing a rotational motion. Specifically, the translational motion is as follows: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing away from the door side wall 32, and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31.

[0437] When the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 During the process, the first direction displacement Pointing away from the door side wall 32, the second direction displacement Pointing to the side away from the front wall 31 of the door.

[0438] The door body 30 opens from the first angle G1 to the tenth angle G 10 During the movement, the trajectory of the axis center point I relative to the door body 30 is recorded as the axis center point trajectory line. Among them, the distance between the eighth midpoint I8 on the axis center point trajectory line and the door front wall 31 is the largest. The distance between the third midpoint I3 on the axis center point trajectory line and the door side wall 32 is the largest.

[0439] It should be noted that “pointing toward the door side wall 32 ” refers to the direction from the end of the door body 30 opposite to the door side wall 32 toward the door side wall 32 ;

[0440] “Directed away from the door sidewall 32 ” means that it is directed from the door sidewall 32 to the direction of the end of the door body 30 opposite to the door sidewall 32 ;

[0441] “Towards the side of the door front wall 31 ” means the direction from the door rear wall 33 to the door front wall 31 ;

[0442] “Directed to the side away from the door front wall 31 ” refers to the direction from the door front wall 31 to the door rear wall 33 .

[0443] In addition, it should be noted that the first direction displacement Second direction displacement All of them are instantaneous relative translation displacements, which are used to illustrate the instantaneous translation movement trend of the door body 30 relative to the box body 10.

[0444] See also Figures 19-26 As shown; in the plane where the top wall of the box body 10 is located, on the side of the box body 10 close to the door body 30, a displacement coordinate system AOB is established. Specifically, in the displacement coordinate system AOB, OB is perpendicular to the plane where the take-in and put-out port is located, and OA is parallel to the plane where the take-in and put-out port is located. In the displacement coordinate system AOB, the direction from the second body side wall to the first body side wall is defined as positive, and the direction from the take-in and put-out port to the door front wall 31 when the door body 30 is closed (from back to front) is defined as positive. It should be noted that, during the opening process of the door body 30, the displacement coordinate system AOB remains stationary relative to the box body 10, and it does not move with the opening of the door body 30. During the opening process of the door body 30, the relative position of the door body coordinate system XOY relative to the displacement coordinate system AOB changes continuously with the different opening angles of the door body 30; and when the opening angle of the door body 30 is determined, the instantaneous relative position of the door body coordinate system XOY relative to the displacement coordinate system AOB remains relatively stationary.

[0445] In some embodiments of the present application, in the displacement coordinate system AOB, the door body 30 has a first direction displacement parallel to the door rear wall 33 The second direction displacement parallel to the door side wall 32 First direction displacement The displacement on the A axis is The displacement on the B axis is Second direction displacement The displacement on the A axis is The displacement on the B axis is

[0446] (1) Figures 19-23 As shown, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to G7 = 90°, as the door body 30 rotates counterclockwise relative to the housing 10, the door side walls 32, door rear wall 33, and door front wall 31 also rotate counterclockwise during this stage of the opening process. Within the plane of the top wall of the housing 10, the door side walls 32 extend outward and forward in the direction from the second side edge N to the first side edge W (the door rear wall 33 to the door front wall 31). The door rear wall 33 extends inward and forward in the direction from the door side walls 32 to the end of the door body 30 opposite the door side walls 32.

[0447] In the above opening process (the first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to G7 = 90°), the door side wall 32 starts to rotate counterclockwise from the state parallel to the reference plane M0, the angle between the door side wall 32 and the plane where the access port is located gradually decreases and the angle between the door side wall 32 and the reference plane M0 gradually increases; that is, when the door body 30 is at the first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to G7 = 90°, relative to the box body 10, along the direction from the second side edge N to the first side edge W, the door side wall 32 extends to the side away from the second body side wall and the access opening. At the same time, as the opening angle of the door body 30 increases, the angle between the door rear wall 33 and the plane where the access opening is located gradually increases, and the angle between the door rear wall 33 and the reference plane M0 gradually decreases; that is, when the door body 30 is opened from the first angle G1 (which can be set, G G =G1 or G G =G1=0°) to G7=90°, relative to the box body 10, along the direction from the door side wall 32 to the end of the door body 30 opposite to the door side wall 32, the door rear wall 33 extends in the direction away from the first body side wall and the take-in and take-out opening (close to the second body side wall and away from the take-in and take-out opening).

[0448] (1.1) During the opening process of the door body 30, the door body 30 includes a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the third angle G3.

[0449] From the above description, it can be seen that: when the door body 30 is at the first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) is opened to the third angle G3, with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing to the side of the door side wall 32 A second direction displacement parallel to the door side wall 32 and pointing to the side of the door front wall 31

[0450] That is, when the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the third angle G3, the first direction displacement Pointing to the outer rear side of the box 10 (outward and rearward side), the second direction displacement It points to the outer front side of the box body 10 (the side facing outward and forward).

[0451] like Figure 19-20 As shown, in the displacement coordinate system AOB, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) when the door body 30 is opened to the third angle G3, the first direction displacement Located in the fourth quadrant (A>0, B<0). Second direction displacement Located in the first quadrant (A>0, B>0).

[0452] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A axis. Displacement in the first direction The displacement on the A axis is Second direction displacement The displacement on the A axis is

[0453] Then there is It can be seen that the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) is opened to the third angle G3, in the displacement coordinate system AOB, the door body 30 has a first translation displacement It can be concluded from this that: relative to the box body 10, the door body 30 has a tendency to move translationally along the positive direction of the A axis while rotating; that is, in the process of the door body 30 opening from the first angle G1 to the third angle G3, the door body 30 has a tendency to move translationally outward while rotating and opening relative to the box body 10.

[0454] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the B axis. Displacement in the first direction The displacement on the B axis is Second direction displacement The displacement on the B axis is

[0455] In some embodiments of the present application, the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) to the third angle G3, Then there is It can be seen that the door body 30 is at a first angle G1 (which can be set, G G =G1 or G G = G1 = 0°) is opened to the third angle G3, in the displacement coordinate system AOB, the door body 30 has a second translation displacement Therefore, it can be concluded that the door body 30 has a tendency to translate forward along the B-axis while rotating relative to the housing 10. That is, when the door body 30 opens from the first angle G1 to the third angle G3, the door body 30 has a tendency to translate forward while rotating relative to the housing 10.

[0456] Combined with the translational trend of the door body 30 along the A-axis direction, when the door body 30 opens from the first angle G1 to the third angle G3, the door body 30 rotates and opens relative to the box body 10 while having a movement trend of translation outward and forward.

[0457] In some embodiments of the present application, During the process of the door body 30 opening from the first angle G1 to the third angle G3, the door body 30 mainly moves forward, while having a relatively small tendency to move outward. This allows the door body 30 to move outward on the one hand, meeting the door closing requirement of the door body 30 with a flip beam, or meeting the door opening requirement when the two door bodies 30 are opened but without a flip beam and with a side sealing strip. On the other hand, the door body 30 moves forward to increase the amount of separation of the door body 30 from the space defined by the storage cabinet 100 in the front-to-back direction, thereby reducing the limitation of the storage cabinet 100 on the maximum angle that the door body 30 of the refrigerator accommodated therein can open. In addition, this also avoids the large outward displacement of the door body 30 in the initial stage of opening, which may cause the first side edge W to interfere with the storage cabinet 100 during the opening process of the door body 30.

[0458] (1.2) During the opening process of the door body 30 , the door body 30 includes a process corresponding to opening from the third angle G3 to the seventh angle G7 = 90° in the second axis trajectory segment.

[0459] From the above description, it can be seen that when the door body 30 is opened from the third angle G3 to the seventh angle G7 = 90°, with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing away from the door side wall 32 A second direction displacement parallel to the door side wall 32 and pointing to the side of the door front wall 31

[0460] That is, when the door body 30 is opened from the third angle G3 to the seventh angle G7 = 90°, the first direction displacement Pointing to the inner front side of the box 10 (inward and forward side), the second direction displacement It points to the outer front side of the box body 10 (the side facing outward and forward).

[0461] like Figure 21-22 As shown, in the displacement coordinate system AOB, during the process of the door body 30 opening from the third angle G3 to the seventh angle G7 = 90°, the first direction displacement of the door body 30 is Located in the second quadrant (A<0,B>0). Second direction displacement Located in the first quadrant (A>0, B>0).

[0462] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the B axis. Displacement in the first direction The displacement on the B axis is Second direction displacement The displacement on the B axis is

[0463] Then there is It can be seen that when the door body 30 is opened from the third angle G3 to the seventh angle G7 = 90°, in the displacement coordinate system AOB, the door body 30 has a second translation displacement Therefore, it can be concluded that the door body 30 has a tendency to translate forward along the B-axis while rotating relative to the housing 10. That is, when the door body 30 opens from the third angle G3 to the seventh angle G7 = 90°, the door body 30 has a tendency to translate forward while rotating relative to the housing 10.

[0464] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A axis. Displacement in the first direction The displacement on the A axis is Second direction displacement The displacement on the A axis is

[0465] In some embodiments of the present application, Figure 21 As shown, the door body 30 is opened from the third angle G3 to the first turning angle G Z1 In the process, Then there is It can be seen that the door body 30 opens from the third angle G3 to the first turning angle G Z1 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving inwards.

[0466] Combined with the translation trend of the door body 30 along the B axis, the door body 30 is opened from the third angle G3 to the first turning angle G Z1 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving inward and forward.

[0467] like Figure 22 As shown, the door body 30 is turned from the first angle G Z1 During the process of opening to the seventh angle G7 = 90°, Then there is It can be seen that the door body 30 is turned from the first angle G Z1 During the process of opening to the seventh angle G7 = 90°, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving outwards in translation.

[0468] Combined with the translation trend of the door body 30 along the B axis, the door body 30 is turned from the first turning angle G Z1 During the process of opening to the seventh angle G7 = 90°, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving outward and forward.

[0469] In summary, when the door body 30 is opened from the third angle G3 to the seventh angle G7 = 90°, the door body 30 rotates and opens relative to the box body 10 with a movement tendency of first moving inward and then moving outward.

[0470] Combined with the translational trend of the door body 30 along the B-axis direction, when the door body 30 opens from the third angle G3 to the seventh angle G7 = 90°, the door body 30 rotates and opens relative to the box body 10 while having a movement trend of first translating inward and forward, and then translating outward and forward.

[0471] Among them, G3<G Z1 <G7.

[0472] In some embodiments of the present application, during the process of the door body 30 opening from the third angle G3 to the seventh angle G7 = 90°, Then there is It can be seen that when the door body 30 is opened from the third angle G3 to the seventh angle G7 = 90°, in the displacement coordinate system AOB, the door body 30 has a first translation displacement Therefore, it can be concluded that the door body 30 has a tendency to translate inwardly along the negative direction of the A-axis while rotating relative to the housing 10. That is, when the door body 30 opens from the third angle G3 to the seventh angle G7 = 90°, the door body 30 has a tendency to translate inwardly while rotating relative to the housing 10.

[0473] Combined with the translational trend of the door body 30 along the B-axis direction, when the door body 30 opens from the third angle G3 to the seventh angle G7 = 90°, the door body 30 rotates and opens relative to the box body 10 while having a movement trend of inward and forward translation.

[0474] In some embodiments of the present application, during the process of the door body 30 opening from the third angle G3 to the seventh angle G7 = 90°, Then there is It can be seen that when the door body 30 is opened from the third angle G3 to the seventh angle G7 = 90°, in the displacement coordinate system AOB, the door body 30 has a first translation displacement Therefore, it can be concluded that the door body 30 has a tendency to translate outward along the A-axis while rotating relative to the housing 10. That is, when the door body 30 opens from the third angle G3 to the seventh angle G7 = 90°, the door body 30 has a tendency to translate outward relative to the housing 10 while rotating and opening.

[0475] Combined with the translational trend of the door body 30 along the B-axis direction, when the door body 30 opens from the third angle G3 to the seventh angle G7 = 90°, the door body 30 rotates and opens relative to the box body 10 while having a movement trend of translation outward and forward.

[0476] Combining (1.1) to (1.2), it can be seen that when the door body 30 is opened from the first angle G1 to the seventh angle G7 = 90°, the door body 30 has a tendency to move inwards in the early stage of opening (G1 to G Z1 ), so as to compensate for the outward displacement of the first side edge caused by simple rotation in the initial stage of opening the door body 30, thereby effectively avoiding interference between the door body 30 and the storage cabinet 100.

[0477] When the door body 30 is opened from the first angle G1 to the seventh angle G7 = 90°, the door body 30 has a tendency to move outwards when opening to 90° (G Z1 ~G7=90°), so as to reduce the obstruction of the door body 30 to the access opening.

[0478] In addition, during the process of opening the door body 30 from the first angle G1 to the seventh angle G7 = 90°, the door body 30 moves forward (G1~G7=90°) so that the door body 30 can be separated from the space limited by the storage cabinet 100 as much as possible, reducing the restriction of the storage cabinet 100 on the opening angle of the door body 30, so that the maximum angle that the door body 30 can open in the storage cabinet 100 is larger.

[0479] (2) Figure 23 As shown, when the door 30 is opened to 90°, the door sidewalls 33 are parallel to the plane of the access opening and perpendicular to the reference plane M0. At this point, the door rear wall 33 is parallel to the reference plane M0 and perpendicular to the plane of the access opening. That is, relative to the box body 10, along the direction from the second side edge N to the first side edge W, the door sidewalls 32 extend from inside to outside; along the direction from the door sidewalls 32 to the end of the door body 30 opposite the door sidewalls 32, the door rear wall 33 extends from back to front.

[0480] During the opening process of the door body 30 , the door body 30 includes a process corresponding to when the door body 30 is opened to the seventh angle G7 = 90° in the fourth axis trajectory segment.

[0481] From the above description, it can be seen that when the door body 30 is opened to the seventh angle G7 = 90°, with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing away from the door side wall 32 A second direction displacement parallel to the door side wall 32 and pointing to the side of the door front wall 31

[0482] That is, when the door body 30 is opened to the seventh angle G7 = 90°, the first direction displacement Pointing to the front side of the box 10 (forward side), the second direction displacement It points to the outside of the box body 10 (outward).

[0483] like Figure 23 As shown, in the displacement coordinate system AOB, when the door body 30 is opened to the seventh angle G7 = 90°, the first direction displacement of the door body 30 is Along the B axis (A=0, B>0). Second direction displacement Along the A axis (A>0, B=0).

[0484] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A axis. Displacement in the first direction The displacement on the A axis is Second direction displacement The displacement on the A axis is

[0485] In some embodiments of the present application, when the door body 30 is opened to the seventh angle G7 = 90°, It can be seen that when the door body 30 is opened to the seventh angle G7 = 90°, in the displacement coordinate system AOB, the door body 30 has a first translation displacement It can be concluded that the door body 30 has a tendency to translate along the positive direction of axis A while rotating relative to the box body 10. That is, when the door body 30 is opened to the seventh angle G7 = 90°, the door body 30 has a tendency to translate outward while rotating relative to the box body 10.

[0486] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the B axis. Displacement in the first direction The displacement on the B axis is Second direction displacement The displacement on the B axis is

[0487] Then there is It can be seen that when the door body 30 is opened to the seventh angle G7 = 90°, in the displacement coordinate system AOB, the door body 30 has a second translation displacement It can be concluded that the door body 30 has a tendency to translate forwardly along the B axis while rotating relative to the box body 10. That is, when the door body 30 is opened to the seventh angle G7 = 90°, the door body 30 has a tendency to translate forward while rotating relative to the box body 10.

[0488] Combined with the translation tendency of the door body 30 along the A-axis direction, when the door body 30 is opened to the seventh angle G7 = 90°, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of translation outward and forward.

[0489] (3) Figure 24-26 As shown, when the door body 30 is rotated from the seventh angle G7 = 90 degrees to G 10 (G 10 During the process of rotating the door body 30 counterclockwise relative to the housing 10 (>90°), the door sidewall 32 also rotates counterclockwise during this stage of the opening process. Within the plane of the top wall of the housing 10, the door sidewall 32 extends outward and rearward in the direction from the second side edge N to the first side edge W. The door rear wall 33 extends outward and forward in the direction from the door sidewall 32 to the end of the door body 30 opposite the door sidewall 32.

[0490] In the above opening process, the door side wall 32 starts to rotate counterclockwise from the state perpendicular to the reference plane M0 (when the door body 30 is opened 90 degrees), and the angle between the door side wall 32 and the plane where the access port is located gradually increases and the angle between the door side wall 32 and the reference plane M0 gradually decreases; that is, when the door body 30 rotates and opens from G7 = 90 degrees to G10 During the process, relative to the box body 10, along the direction from the second side edge N to the first side edge W, the door side wall 32 extends away from the second body side wall and closer to the access opening. At the same time, the angle between the door rear wall 33 and the plane where the access opening is located gradually decreases and the angle between it and the reference plane M0 gradually increases; that is, when the door body 30 rotates from G7 = 90 degrees to G 10 During the opening and closing process, relative to the box body 10, the door rear wall 33 extends in a direction away from the second body side wall and the access opening along the direction from the door side wall 32 to the end of the door body 30 opposite to the door side wall 32.

[0491] (3.1) During the opening process of the door body 30 , the door body 30 includes a process of opening from the seventh angle G7 = 90° to the eighth angle G8 corresponding to the second axis trajectory segment.

[0492] From the above description, it can be seen that when the door body 30 is opened from the seventh angle G7 = 90° to the eighth angle G8, with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing away from the door side wall 32. A second direction displacement parallel to the door side wall 32 and pointing to the side of the door front wall 31

[0493] That is, when the door body 30 is opened from the seventh angle G7 = 90° to the eighth angle G8, the first direction displacement Pointing to the outer front side of the box 10 (outward and forward side), the second direction displacement It points to the outer rear side of the box body 10 (outward and rearward).

[0494] like Figure 24 As shown, in the displacement coordinate system AOB, during the process of the door body 30 opening from the seventh angle G7 = 90° to the eighth angle G8, the first direction displacement of the door body 30 is Located in the first quadrant (A>0, B>0). Second direction displacement Located in the fourth quadrant (A>0, B<0).

[0495] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A axis. Displacement in the first direction The displacement on the A axis is Second direction displacement The displacement on the A axis is

[0496] Then there is It can be seen that when the door body 30 is opened from the seventh angle G7 = 90° to the eighth angle G8, in the displacement coordinate system AOB, the door body 30 has a first translation displacement It can be concluded from this that: relative to the box body 10, the door body 30 has a tendency to move translationally along the positive direction of the A axis while rotating; that is, in the process of the door body 30 opening from the seventh angle G7=90° to the eighth angle G8, the door body 30 has a tendency to move translationally outward while rotating and opening relative to the box body 10.

[0497] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the B axis. Displacement in the first direction The displacement on the B axis is Second direction displacement The displacement on the B axis is

[0498] In some embodiments of the present application, during the process of the door body 30 opening from the seventh angle G7 = 90° to the eighth angle G8, Then there is It can be seen that when the door body 30 is opened from the seventh angle G7 = 90° to the eighth angle G8, in the displacement coordinate system AOB, the door body 30 has a second translation displacement Therefore, it can be concluded that the door body 30 has a tendency to translate forwardly along the B-axis while rotating relative to the housing 10. That is, when the door body 30 opens from the seventh angle G7 = 90° to the eighth angle G8, the door body 30 has a tendency to translate forwardly while rotating relative to the housing 10.

[0499] Combined with the translational trend of the door body 30 along the A-axis direction, when the door body 30 opens from the seventh angle G7 = 90° to the eighth angle G8, the door body 30 rotates and opens relative to the box body 10 while having a movement trend of translation outward and forward.

[0500] In some embodiments of the present application, As the door 30 opens from the seventh angle G7 = 90° to the eighth angle G8, the door 30 primarily moves forward, with a slight tendency to move outward. This allows the door 30 to escape as much as possible from the space confined by the storage cabinet 100, reducing the restriction imposed by the storage cabinet 100 on the opening angle of the door 30, thereby increasing the maximum angle that the door 30 can open within the storage cabinet 100.

[0501] (3.2) During the opening process of the door body 30, the door body 30 includes the opening from the eighth angle G8 to the tenth angle G corresponding to the third axis trajectory segment. 10 process.

[0502] From the above description, it can be seen that when the door body 30 is opened from the eighth angle G8 to the tenth angle G 10In the process, with the box body 10 as a reference, the door body 30 has a first direction displacement parallel to the door rear wall 33 and pointing away from the door side wall 32. A second direction parallel to the door side wall 32 and pointing away from the door front wall 31

[0503] That is, when the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 During the process, the first direction displacement Pointing to the outer front side of the box 10 (outward and forward side), the second direction displacement It points to the inner front side of the box body 10 (the side facing inward and forward).

[0504] like Figure 25-26 As shown, in the displacement coordinate system AOB, the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 During the process, the first direction displacement of the door body 30 Located in the first quadrant (A>0, B>0). Second direction displacement Located in the second quadrant (A<0, B>0).

[0505] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the B axis. Displacement in the first direction The displacement on the B axis is Second direction displacement The displacement on the B axis is

[0506] Then there is It can be seen that the door body 30 opens from the eighth angle G8 to the tenth angle G 10 During the process, in the displacement coordinate system AOB, the door body 30 has a second translation displacement It can be concluded that: relative to the box body 10, the door body 30 has a tendency to move in a positive direction along the B axis while rotating. That is, the door body 30 opens from the eighth angle G8 to the tenth angle G 10 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving forward in translation.

[0507] Displacement in the first direction and the second direction displacement Displacement decomposition is performed on the A axis. Displacement in the first direction The displacement on the A axis is Second direction displacement The displacement on the A axis is

[0508] In some embodiments of the present application, Figure 25 As shown, the door body 30 is opened from the eighth angle G8 to the second turning angle G Z2 In the process, Then there is It can be seen that the door body 30 opens from the eighth angle G8 to the second turning angle G Z2 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving inwards.

[0509] Combined with the translation trend of the door body 30 along the B-axis direction, the door body 30 is opened from the eighth angle G8 to the second turning angle G Z2 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving inward and forward.

[0510] like Figure 26 As shown, the door body 30 is turned from the second angle G Z2 Open to the tenth angle G 10 In the process, Then there is It can be seen that the door body 30 is at the second turning angle G Z2 Open the tenth angle G 10 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a tendency to move outwards.

[0511] Combined with the translation trend of the door body 30 along the B axis, the door body 30 is turned from the second turning angle G Z2 Open to the tenth angle G 10 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving outward and forward.

[0512] In summary, the door body 30 is turned from the eighth angle G8 to the tenth angle G 10 During the opening process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of first moving inward and then moving outward.

[0513] Combined with the translation trend of the door body 30 along the B axis, the door body 30 moves from the eighth angle G8 to the tenth angle G 10 During the opening process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of first moving inward and forward, and then moving outward and forward.

[0514] Among them, G8<G Z2 <G 10 .

[0515] In some embodiments of the present application, the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 In the process, Then there is It can be seen that the door body 30 opens from the eighth angle G8 to the tenth angle G 10 During the process, in the displacement coordinate system AOB, the door body 30 has a first translation displacement It can be concluded that: relative to the box body 10, the door body 30 has a tendency to move in the negative direction of the A axis while rotating. That is, the door body 30 opens from the eighth angle G8 to the tenth angle G 10 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving inwards.

[0516] Combined with the translation trend of the door body 30 along the B axis, the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving inward and forward.

[0517] In some embodiments of the present application, the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 In the process, Then there is It can be seen that the door body 30 opens from the eighth angle G8 to the tenth angle G 10 During the process, in the displacement coordinate system AOB, the door body 30 has a first translation displacement It can be concluded that: relative to the box body 10, the door body 30 has a tendency to move in the positive direction of the A axis while rotating. That is, the door body 30 opens from the eighth angle G8 to the tenth angle G 10 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a tendency to move outwards.

[0518] Combined with the translation trend of the door body 30 along the B axis, the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 During the opening and closing process, the door body 30 rotates and opens relative to the box body 10 while having a movement tendency of moving outward and forward.

[0519] In some embodiments of the present application, the door body 30 is opened from the eighth angle G8 to the tenth angle G 10 In the process, The door body 30 opens from the eighth angle G8 to the tenth angle G 10 During this process, the door body 30 primarily moves forward, with a tendency to move slightly outward. This allows the door body 30 to escape as much as possible from the space confined by the storage cabinet 100, reducing the restriction imposed by the storage cabinet 100 on the opening angle of the door body 30, thereby increasing the maximum opening angle of the door body 30 within the storage cabinet 100. Furthermore, the door body 30 primarily moves forward, with a tendency to move slightly inward, minimizing obstruction of the access opening by the door body 30.

[0520] It should be noted that the above description only uses some angles in the range of 0 to 90 degrees, 90 degrees, 90 degrees to G 10 Some angles within the range are used as representatives to illustrate the overall movement trend of the door body 30, but they can represent the movement trend within the corresponding range, and can illustrate that the hinge assembly with the above trajectory characteristics of the utility model can make the door body 30 translate along the A-axis and B-axis throughout the entire process of rotating and opening.

[0521] The hinge assembly with the trajectory feature of the present invention enables the door body 30 to have a specific translational movement while rotating during the opening process. At the same time, its trajectory (guide trajectory line S and guide trajectory line K) is smooth and has no sharp points, effectively ensuring the smoothness and stability of the opening of the door body 30.

[0522] In some embodiments of the present application, Figure 27-28 As shown, the refrigerator includes two doors 30 disposed opposite each other, which cooperate to open or close the access opening. A side sealing strip 3 is provided on the side of each door 30, away from its sidewall 32. When the doors 30 are closed, the side sealing strip 3 on one door 30 seals against the side sealing strip 3 on the other door 30. That is, when the doors 30 are closed, the side sealing strips 3 squeeze into the gap between the doors 30, effectively sealing the space between the doors 30 and the housing 10 and preventing cold air from escaping.

[0523] Combined with the above hinge assembly settings, the hinge assembly has a motion characteristic of guiding the door body 30 to move outward first when opening, and the door body 30 is in a closed state (settable, G G =G1 or G G =G1=0° or G G =G2 or G G =G2=0°) when opening to the third angle G3, the door body 30 moves outward, which can avoid the situation where one of the two oppositely arranged door bodies 30 is opened and the other door body 30 is driven to open, thereby effectively reducing the loss of cooling capacity; at the same time, it can effectively reduce the obstruction of the door body 30 to the access port.

[0524] Combined with the above hinge assembly settings, the hinge assembly has the motion characteristics of guiding the door body 30 to move outward first and then inward when opening, and the door body 30 is in a closed state (settable, G G =G1 or G G =G1=0° or G G =G2 or G G= G2 = 0°) to the third angle G3, the door body 30 moves outward, which can prevent the other door body 30 from being opened when one of the two oppositely arranged door bodies 30 is opened, effectively reducing the loss of cooling capacity; at the same time, it can effectively reduce the obstruction of the door body 30 to the access opening. Z1 ), the door body 30 has a tendency to move inward, and the opened door body 30 can be moved inward after the two door bodies 30 are separated, which can effectively compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 30, and limit the distance of the first side edge W beyond the reference plane M0 to not exceed the distance between the storage cabinet 100 and the side wall of the refrigerator body, effectively avoiding interference between the door body 30 and the storage cabinet 100 when it is opened, further reducing the restrictions of the storage cabinet 100 space on the size of the refrigerator that can be accommodated, and improving the utilization rate of the storage cabinet 100 space. Furthermore, setting the door body 30 to move inward and / or forward during the process of opening to the maximum angle can reduce the restrictions of the storage cabinet 100 on the maximum angle that the door body 30 can open, so that the maximum angle that the door body 30 of the refrigerator installed in the storage cabinet 100 can be opened is larger.

[0525] like Figures 29 to 33 As shown, in some embodiments of the present application, the refrigerator includes two door bodies 30 arranged opposite to each other, and the two door bodies 30 arranged opposite to each other cooperate to open or close the access opening. When the two door bodies 30 are closed, a flip beam 9 is provided on the side of one door body 30 close to the other door body 30. A guide rail 91 is provided on the top wall of the storage chamber of the refrigerator. The flip beam 9 can slide with the guide rail 91 to achieve switching of the flip beam 9 to different angles relative to the door bodies 30. When the two door bodies 30 are closed, the flip beam 9 closes the gap between the two door bodies 30 and the box body 10 to effectively prevent cold air from escaping.

[0526] In some embodiments of the present application, the flip beam is provided on the inner lining surface of the door body 30 where it is located.

[0527] In some embodiments of the present application, the flip beam is connected to the door body 30 via a door hinge. The door hinge and the flip beam are elastically connected using a torsion spring.

[0528] A guide block 90 is provided on the top of the flip beam. The guide block 90 serves as a rotating component of the flip beam 9 and cooperates with the guide rail 91 to achieve switching of the flip beam 9 to different angles relative to the door body 30.

[0529] In some embodiments of the present application, the flip beam 9 includes a door beam rear cover. The door hinge includes a first door hinge and a second door hinge. The door beam rear cover is connected to the door body 30 through the first door hinge and the second door hinge.

[0530] The door beam rear cover is elastically connected to the two door hinges by torsion springs, wherein the first door hinge is located above the second door hinge.

[0531] The guide block 90 is arranged on the top of the door turning beam rear cover.

[0532] There are through holes for the torsion spring force arm on the door hinge and the door beam rear cover, and the torsion spring is used to connect the upper and lower door hinges with the door beam rear cover.

[0533] In some embodiments of the present application, the first door hinge is connected to the door swing beam rear cover via a first torsion spring, and the second door hinge is connected to the door swing beam rear cover via a second torsion spring. When the tilt beam 9 rotates about the door hinge, the first and second torsion springs store or release elastic energy to ensure stable rotation and timely reset of the door swing beam rear cover.

[0534] When the door body 30 is open, the flip beam 9 is tightly attached to the side of the door hinge fixed to the inner lining of the door body 30 due to the torsion force of the torsion springs (the first torsion spring and the second torsion spring).

[0535] like Figure 31-33 As shown, when the door body 30 is closed from the open state, an external force is first applied to the door body 30. Under the action of the external force, the door body 30 gradually closes until the door body 30 closes to the angle G. S When the turning beam 9 is turned, the guide block 90 at the top end of the turning beam 9 contacts the guide rail 91.

[0536] When the door body 30 is closed to the angle G S When the external force is continuously applied, the door body 30 continues to move in the closing direction, and the guide block 90 at the top of the flip beam 9 enters the guide rail 91, and the guide block 90 interacts with the guide rail 91. During the closing process, the guide block 90 begins to flip due to the pressure of the guide rail 91, and the torsion spring is compressed in the radial direction.

[0537] When the flip beam 9 flips to the angle G' F (At this time, the door body 30 is at an angle G F state), the critical value of the torsion spring is reached.

[0538] The door 30 is closed to the angle G F After that, the torsion spring begins to stretch, and the turnover beam 9 is quickly turned into place to release the torsion spring torsion force. Until the door body 30 is closed, the torsion spring torsion force is released and reaches a relaxed state again.

[0539] When the door body 30 is closed to the angle G F After that, the turning beam 9 is automatically closed.

[0540] In some embodiments of the present application, after the door body 30 is closed, the flip beam 9 contacts the seal provided on the door body 30, effectively preventing cold air from overflowing from the gaps between the two pairs of open doors.

[0541] If the flip beam 9 is flipped to the angle G' F When the external force is removed, the torsion spring does not reach the critical value, and the guide block 90 on the top of the flip beam 9 cannot effectively complete the flip after entering the guide rail 91 on the box body and is stuck. The flip beam 9 cannot automatically complete the flip, resulting in the door body 30 with the flip beam unable to close in place, causing the refrigerator's low-temperature storage to fail.

[0542] Combined with the above arrangement of the hinge assembly, the hinge assembly has the motion characteristic of guiding the door body 30 to move outward first when opening, and the door body 30 is closed by the closing angle G G During the process of opening to the third angle G3, the door body 30 moves outward. Correspondingly, the door body 30 moves from the third angle G3 to the closing angle G G (Close angle G G =G1 or G G =G1=0° or G G =G2 or G G =G2=0°), during the closing process, the door body 30 moves inward.

[0543] Corresponding to the flipping of the flip beam 9 in the final stage of closing the door body 30, the door body 30 moves inward, so that the force driving the flip beam 9 to flip will not be partially offset as the door body 30 moves outward while closing, thereby avoiding the guide block 90 on the top of the rotating beam from entering the track groove on the box body and being unable to effectively complete the flipping and being stuck, effectively ensuring that the door body 30 with the flip beam 9 is closed in place, thereby ensuring the effectiveness of low-temperature storage in the refrigerator.

[0544] In some embodiments of the present application, the third angle G3 is greater than or equal to the angle G F . When the door body 30 is closed, the flip beam 9 starts to flip automatically and completes the automatic flipping during the inward displacement process. In the hinge assembly with the above trajectory characteristics, when the door body 30 is closed from the open state, the inward movement of the door body 30 can prompt the elastic potential energy released by the spring to be effectively converted into kinetic energy to flip the flip beam 9, and it is not offset by the outward movement of the door body 30, resulting in the flip beam 9 being unable to effectively complete the flipping and being stuck, effectively ensuring that the door body 30 with the flip beam 9 is closed in place, thereby ensuring the effectiveness of low-temperature storage in the refrigerator.

[0545] In some embodiments of the present application, the third angle G3 is greater than or equal to the angle G S. When the door body 30 is closed, during the displacement process of moving inward, the guide block 90 at the top of the flip beam 9 contacts the guide rail 91 and completes the automatic flip. The hinge assembly with the above trajectory characteristics, in the process of the door body 30 closing from the open state, when the door body 30 drives the flip beam 9 to flip, the door body 30 moves inward, so that the force driving the flip beam 9 to flip will not be partially offset as the door body 30 moves outward while closing, thereby avoiding the guide block 90 at the top of the rotating beam from entering the track groove on the box body and being unable to effectively complete the flip and being stuck, effectively ensuring that the door body 30 with the flip beam 9 is closed in place, thereby ensuring the effectiveness of low-temperature storage in the refrigerator.

[0546] In some embodiments of the present application, the third angle G3 is greater than or equal to the angle G F At the same time, the third angle G3 is less than or equal to the angle G S . The hinge assembly with the above trajectory characteristics, when the door body 30 is closed from the open state, the door body 30 drives the flip beam 9 to flip, and the door body 30 moves inward, so that the force driving the flip beam 9 to flip will not be partially offset as the door body 30 moves outward while closing, thereby avoiding the guide block 90 on the top of the rotating beam from entering the trajectory groove on the box body and being unable to effectively complete the flip and being stuck, effectively ensuring that the door body 30 with the flip beam 9 is closed in place, thereby ensuring the effectiveness of low-temperature storage in the refrigerator.

[0547] Combined with the above arrangement of the hinge assembly, the hinge assembly has the motion characteristic of guiding the door body 30 to move outward first and then inward when opening, and the door body 30 moves from the third angle G3 to the closing angle G G (Close angle G G =G1 or G G =G1=0° or G G =G2 or G G = G2 = 0°) during the closing process, the door body 30 moves inward, so that the force driving the flip beam 9 to flip will not be partially offset as the door body 30 moves outward while closing, thereby preventing the guide block 90 on the top of the rotating beam from entering the track groove on the box body and failing to complete the flip and getting stuck, effectively ensuring that the door body 30 with the flip beam 9 is closed in place, thereby ensuring the effectiveness of low-temperature storage of the refrigerator. At the same time, it can effectively reduce the amount of obstruction of the door body 30 on the access port. The door body 30 continues to open from the third angle G3 (from the third angle G3 to the first turning angle G Z1), the door body 30 has a tendency to move inward, and the opened door body 30 can be moved inward after the two door bodies 30 are separated, which can effectively compensate for the outward displacement of the first side edge W caused by the simple rotation of the door body 30, and limit the distance of the first side edge W beyond the reference plane M0 to not exceed the distance between the storage cabinet 100 and the side wall of the refrigerator body, effectively avoiding interference between the door body 30 and the storage cabinet 100 when it is opened, further reducing the restrictions of the storage cabinet 100 space on the size of the refrigerator that can be accommodated, and improving the utilization rate of the storage cabinet 100 space. Furthermore, setting the door body 30 to move inward and / or forward during the process of opening to the maximum angle can reduce the restrictions of the storage cabinet 100 on the maximum angle that the door body 30 can open, so that the maximum angle that the door body 30 of the refrigerator installed in the storage cabinet 100 can be opened is larger.

[0548] like Figure 34 As shown, in some embodiments of the present application, the first hinge member is located at a first mating portion at one end thereof away from the side wall of the first body, and a second mating portion is provided at the end of the door body 30 close to the first hinge member, and the second mating portion is used to cooperate with the first mating portion to realize locking and unlocking of the door body 30 and the box body 10.

[0549] As a possible arrangement, the second matching portion is located on a side of the second hinge component away from the door side wall 32 .

[0550] When the door body 30 is closed from an open state, an external force is first applied to the door body 30. Under the action of the external force, the door body 30 gradually closes. As the door body 30 rotates to close, the second matching portion gradually approaches the first matching portion.

[0551] When the door 30 is closed to the angle G B0 When the second mating portion contacts the first mating portion, the door 30 continues to close under the action of an external force. The first and second mating portions interact, causing the second mating portion to elastically deform. Under the combined action of the external force and the force acting on the first mating portion, the second mating portion gradually approaches the first mating portion, and the elastic deformation of the second mating portion gradually increases.

[0552] When the door 30 is closed to the angle G B1 , the elastic deformation of the second matching portion reaches the maximum deformation during the closing process of the door body 30.

[0553] When the door 30 is closed and reaches the angle G B1 Then, the second mating portion continues to move in the closing direction, and the elastic energy stored in the elastic deformation of the second mating portion is released, and the second mating portion returns to the relaxed state, and the door body 30 is quickly and automatically closed in place. Until the door body 30 is closed, the second mating portion is locked with the first mating portion, and the door body 30 and the box body 10 are locked.

[0554] Above, G B0 >GB1 .

[0555] In some embodiments of the present application, G B0 Set to any value between 15° and 20°, G B1 Set to any value between 3° and 8°.

[0556] From the above, it can be seen that the door body 30 is closed to the angle G B1 Afterwards, under the interaction of the first matching portion and the second matching portion, the door body 30 is automatically closed.

[0557] It should be noted that in some embodiments of the present application, during the closing process of the door body 30, the external force continues to act until the door body 30 is closed to G B1 After the door body 30 rotates and closes to the maximum elastic deformation of the second matching portion, the external force is removed and the door body 30 can automatically close. B1 After the external force is removed, the door body 30 has an inertial force, and the inertial force also has the characteristic of making the door body 30 maintain its original closing movement trend.

[0558] From the above, it can be seen that the door body 30 is formed by the angle G B0 Close to angle G B1 During the process, the second matching portion undergoes elastic deformation.

[0559] When the door 30 is closed to the angle G B1 When the elastic deformation of the second matching portion reaches the maximum deformation during the closing process of the door body 30.

[0560] The door body 30 is formed by the angle G B1 In the process of reaching the closed state, the elastic force of the second matching portion is released and the door body 30 is automatically closed.

[0561] That is, under the structural setting of the first matching portion and the second matching portion, the door body 30 is B1 In the process of closing the door 30, the door body 30 has the characteristic of automatically closing.

[0562] Combined with the above arrangement of the hinge assembly, the hinge assembly has the motion characteristic of guiding the door body 30 to move outward first when opening, and the door body 30 is closed by the closing angle G G During the process of opening to the third angle G3, the door body 30 moves outward. Correspondingly, the door body 30 moves from the third angle G3 to the closing angle G G During the closing process, the door body 30 moves inward.

[0563] In some embodiments of the present application, G B1 ≥G Z1 That is, the door body 30 is in the process of automatically closing (by the angle G B1The door body 30 moves inwards, exerting an inward force on the flip beam 9, which causes the flip beam to flip. B1 In the process of continuing to close, it has the characteristic of automatic closing, and the door body 30 maintains the tendency to move inward, so the inward force exerted by the door body 30 on the flip beam 9 is always present, which can ensure that the flip beam 9 flips into place and the door body 30 is closed in place.

[0564] In some embodiments of this application, refer to Figure 34 The door body 30 includes a mounting block mounted on the door body 30 at a position opposite the hinge plate 40. The guide portion 50, the guide portion 60, and the second mating portion are formed on the mounting block. The first mating portion is formed on the extension portion 402 of the hinge plate 40 and is located away from the side wall of the first body.

[0565] The following description will be made by taking the mounting block provided at the lower end of the door body 30 as an example. Figure 34 As shown, a guide groove is formed on the mounting block. The guide groove includes a groove bottom and a circumferential groove wall surrounding the edge of the groove bottom. A guide groove is formed on the mounting block. The guide groove includes a groove bottom and a circumferential groove wall surrounding the edge of the groove bottom.

[0566] The door body 30 is formed with a receiving groove 37 for fixing the mounting block.

[0567] As an practicable manner, the mounting block is placed in the receiving groove 37, and then the mounting block is fastened to the door body 30 by a first fixing member. Specifically, the first fixing member can be set as a screw or the like.

[0568] In some embodiments of the present application, the mounting block includes a plate body 81 . The guide portion 50 and the guide portion 60 are formed on the plate body 81 .

[0569] The plate body 81 surrounds the guide groove and the circumferential side wall of the guide groove. The guide groove and the guide groove are formed on the plate body 81.

[0570] In some embodiments of the present application, a first fixing member connecting the mounting block and the receiving groove 37 fixes the plate body 81 and the door body 30 together.

[0571] In some embodiments of the present application, the second mating portion on the mounting block is configured as a locking structure. Specifically, the second mating portion includes a locking hook 82 disposed on the side of the plate 81 away from the door sidewall 32. The locking hook 82 first extends away from the door sidewall 32, then bends toward the side closer to the door rear wall 33 and the door sidewall 32, with the opening of the locking hook 82 facing the plate 81 (the opening of the locking hook 82 faces the door sidewall 32).

[0572] The free end of the locking hook 82 is located on a side thereof close to the door rear wall 33 .

[0573] A first engaging portion, located on the side of the hinge plate 40 away from the first sidewall, is provided as a stopper 403. The stopper 403 has a hooking gap 404 on the side closest to the refrigerator body 10. When the door 30 is closed, the free end of the lock hook 82 is received within the hooking gap 404, and the stopper 403 is located within the lock hook 82. The lock hook 82 on the door 30 hooks onto the stopper 403 on the hinge plate 40, thereby locking the door 30 and the refrigerator body 10. This prevents the door 30 from being loosely closed and affecting the refrigerator's refrigeration and freezing performance. When the door 30 is opened, the lock hook 82 is deformed by the force, overcoming the obstruction of the stopper 403 and disengaging from the stopper 403.

[0574] The lock hook 82 may include a root portion 83 and a hook portion 84. The root portion 83 is connected to the plate 81, and the hook portion 84 is connected to the root portion 83. The hook portion 83 extends away from the door side wall 32 and then bends toward the side closer to the door rear wall 33 and the door side wall 32. Screws are inserted through the root portion 83 to connect it to the door body 30 to strengthen the connection between the root portion 83 and the door body 30. This ensures that only the hook portion 84 deforms when the lock hook 82 is released from the stop portion 403.

[0575] It can be arranged that the free ends of the hook portion 84 and the stop portion 403 are both in an arc shape, which is conducive to the hook portion 84 smoothly hooking onto the stop portion 403 or detaching from the stop portion 403 along the arc.

[0576] When the door body 30 is closed from the open state, the door body 30 gradually closes under the action of an external force. As the door body 30 rotates to close, the free end of the hook portion 84 gradually approaches the stop portion 403.

[0577] When the door 30 is closed to the angle G B0 , the hook portion 84 contacts the stop portion 403 .

[0578] Then, under the action of external force, the door body 10 continues to close, the stop portion 403 interacts with the hook portion 84, and the hook portion 84 undergoes elastic deformation. Under the combined action of the external force and the force of the stop portion 403, the hook portion 82 gradually enters the hook gap 404 (that is, the stop portion 403 enters the hook portion 84).

[0579] When the door 30 is closed to G B1 When the elastic deformation of the hook portion 84 reaches the maximum deformation during the closing process of the door body 30.

[0580] When the door 30 is closed and reaches the angle G B1 Afterwards, the elastic energy stored in the elastic deformation of the hook portion 82 is gradually released, and under the action of the stop portion 403, the hook portion 82 recovers to the relaxed state and drives the hook portion 82 further into the hook gap 404, so that the door body 30 is automatically closed in place.

[0581] When the door 30 is closed, the lock hook 82 is locked with the hinge plate 40, thus locking the door 30 and the box body 10. That is, the door 30 is closed to the angle G. B1 After that, the door body 30 has the characteristic of automatic closing.

[0582] It should be noted that the setting of the first hinge and the second hinge for precisely controlling the door body 30 to rotate open and move in a specific direction needs to form a structural setting with various trajectory characteristics. It is necessary to achieve the coordinated cooperation of the first hinge and the second hinge through refined design, and ultimately achieve the precise control of the door body 30 to perform complex movements.
