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 generally built into a customized storage cabinet. In order to improve the fit of the refrigerator in the external storage cabinet, the gap between the outer wall of the refrigerator and the inner wall of the storage cabinet is generally set to be very small. When the refrigerator door is opened, the rotating door hinge vertical edge is easy to hit the inner wall of the external storage cabinet. Due to the space limitation of the storage cabinet, in order to ensure that the door body can be opened effectively, the corner of the door body must not exceed the size of the cabinet too much during the door opening process.

[0003] At present, in order to meet the needs of embedded installation, most of them are equipped with a double shaft on one of the door and the box body, and a guide structure matched with the double shaft is arranged on the other to control the door to move inward while rotating to open, so as to meet the needs of embedded installation. Under the setting of the combination of the double shaft and the guide, the door moves inward during the opening process, so as to ensure that the corner of the door body does not exceed the size of the box body too much during the door opening process.

[0004] When customizing the storage cabinet in which the built-in refrigerator is embedded, usually, one of the standards is that when the refrigerator door is closed, the front wall of the door is flush with the plane where the opening end of the storage cabinet is located, so that the size of the refrigerator matches the size of the storage cabinet and a hidden flush installation is achieved; in addition, another standard is that the distance between the inner wall of the storage cabinet and the outer wall of the refrigerator or the side wall of the door when the door body is closed meets the minimum value for installing the refrigerator in the storage cabinet, so that the refrigerator can make full use of the installation space limited by the storage cabinet and achieve installation without / without a small gap. On the premise that the door of the built-in refrigerator can be opened smoothly without interfering with the inner wall of the storage cabinet, as the opening angle of the refrigerator door increases, the front wall of the door approaches the end of the adjacent storage cabinet near its opening; when the front wall of the door contacts the end of the adjacent storage cabinet near its opening, the door body is opened to the extreme 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

The first hinge is arranged on the box body 10 and close to the first side wall, and the second hinge is arranged at the end of the door body 30 close to the first hinge. The first hinge cooperates with the second hinge to allow the box body 10 and the door body 30 to rotate relative to each other. The door body 30 includes a door front wall 31 that is away from the box body 10 when the door body 30 is closed, a door rear wall 33 that is arranged opposite to the door front wall 31, and a door side wall 32 that is close to the first hinge and connected to the door front wall 31. For example, when the first hinge is located on the right side of the box body 10, the right side of the door body 30 is the door side wall 32 when the door body 30 is closed. When the first hinge is located on the left side of the box body 10, the left side wall of the door body 30 is the door side wall 32 when the door body 30 is closed.

[0135] 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 .

[0136] 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.

[0137] In actual production and processing, the intersection of the door front wall 31 and the door side wall 32 is set as a rounded transition, so that a curved surface is formed 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 used as the first side edge W (the same applies to the second side edge N). In this application, for the convenience of description, the theoretical first side edge W and the theoretical second side edge N are used for description.

[0138] In some embodiments of the present application, a door seal 5 is provided on the door rear wall 33. When the door body 30 is closed, the door seal 5 fits with the front end surface of the box body surrounding the access opening to effectively seal the connection between the door body 30 and the box body 10, thereby ensuring that the door body 30 seals the access opening to prevent cold air from escaping. It can be provided that the door seal 5 is annular. The door seal 5 is located between the door rear wall 33 and the front end surface of the box body, and the door rear wall 33 is located on the side of the plane where the access opening of the box body 10 is located close to the door seal 5.

[0139] In some embodiments of the present application, reference Figures 1 to 3 2, the first hinge member includes a hinge plate 40, a first shaft 41 and a second shaft 42 provided on the hinge plate 40. The hinge plate 40 includes: a connecting portion connected to the box body 10 and close to the side wall of the first body, and an extending portion extending forward from the connecting portion. The connecting portion can be fastened to the top wall of the box body 10 by fasteners such as screws, pins and bolts. The extending portion is in the shape of a horizontal plate.

[0140] Specifically, for the hinge at the upper end of the door body 30, the connecting portion 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 is connected to the front end surface of the box body 10. Among them, the first axis 41 and the second axis 42 are formed on the extension of the first hinge. The second axis 42 is located on the side of the first axis 41 away from the side wall of the first body.

[0141] The second hinge member includes: a guide portion 50 and a guide portion 60 located at the end of the door body 30 near the first hinge member. The first shaft 41 is adapted to the guide portion 50, and the second shaft 42 is adapted to 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.

[0142] 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.

[0143] The built-in refrigerator is a refrigerator that is embedded as a whole in a customized storage cabinet 100. The end face of the storage cabinet 100 defining its opening is recorded as the opening end face. The refrigerator is embedded flat in the storage cabinet 100. When the door body of the refrigerator is closed, the door front wall 31 of the door body 30 is flush with the opening end face of the storage cabinet 100. In the utility model, the first shaft 41 cooperates with the guide part 50, and the second shaft 42 cooperates with the guide part 60, so that the door body 30 moves inward a certain distance, so that when the user opens and closes the door body 30 of the refrigerator, the door body 30 of the refrigerator will not collide with the storage cabinet 100, effectively avoiding scratches on the storage cabinet 100 or the door body of the refrigerator.

[0144] It should be noted that the "flush" in the above-mentioned flushness between the front door wall 31 and the opening end face of the storage cabinet 100 includes being on the same plane, or the distance between the two planes is not greater than 2 mm. Specifically, the front door wall 31 is located on the side of the opening end face of the storage cabinet 100 away from the access port, and the distance between the two planes is not greater than 2 mm. Or the front door wall 31 is located on the side of the opening end face of the storage cabinet 100 close to the access port, and the distance between the two planes is not greater than 2 mm.

[0145] In some embodiments of the present application, the first shaft 41 and the second shaft 42 are provided on the extensions at the upper and lower ends of the door body 30, and the guide portion 50 and the guide portion 60 are provided at the upper and lower ends of the door body 30. It should be noted that the arrangement of this embodiment is not limited to being arranged at both the upper and lower ends of the door body 30, and it is arranged as needed to connect the door body 30 and the box body 10.

[0146] In some embodiments of the present application, Figure 1-Figure 2 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 M 0 , reference plane M 0 The side 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.

[0147] When the refrigerator is placed in the storage cabinet 100 for use, in order to prevent factors such as uneven ground and deformation of the storage cabinet 100, the storage cabinet 100 is set in size so that the storage cabinet 100 and the side of the refrigerator (the first body side wall, i.e., the reference plane M) are aligned. 0 ) distance α`. In order to ensure that the door 30 of the refrigerator opens normally, the first side edge W of the door 30 cannot exceed the side surface of the box body 10 (reference plane M) during the rotation process. 0 ) is too much to prevent the first side edge W from colliding with the storage cabinet 100 and causing the door body 30 to be unable to open normally.

[0148] In some embodiments of the present application, α` is any value between 3 and 5 mm.

[0149] 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 containing cabinet 100 is 3 mm.

[0150] In order to meet the above requirements, the door body 30 needs to be able to move inward during the rotation process, so that the first side edge W does not exceed the side wall (reference plane M of the box body 10) 0 ). Taking the hinge plate 40 being arranged 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) as an example, the inner side is the left side, that is, the door body 30 needs to be able to move to the left. Taking the hinge plate 40 being arranged on the left side of the door body 30 as an example, the inner side is the right side, that is, the door body 30 needs to be able to move to the right.

[0151] In some embodiments of the present application, the central axis of the first axis 41 is recorded as the first central axis P, and the central axis of the second axis 42 is recorded as the second central axis Q.

[0152] In some embodiments of the present application, Figure 2 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.

[0153] 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. The guide groove is located on a side of the guide groove close to the first side edge W.

[0154] In some embodiments of the present application, along the direction from the door rear wall 33 to the door front wall 31 , the distance between the guide groove and the door side wall 32 gradually decreases.

[0155] In some embodiments of the present application, the trajectory line along which the guide portion 50 guides the relative movement of the first central axis P is the guide trajectory line S, and the trajectory line along which the guide portion 60 guides the relative movement of the second central axis Q is the guide trajectory line K.

[0156] The guide track line S is located on a side of the guide track line K close to the first side edge W.

[0157] 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 .

[0158] 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.

[0159] 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 to the door side wall 32 , a distance between the guide track line S and the door front wall 31 gradually decreases.

[0160] Along the direction from the end of the door body 30 away from the door side wall 32 to the door side wall 32, the distance between the guide track line K and the door front wall 31 first increases, then decreases, and then increases again.

[0161] 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 .

[0162] The guide track line K first extends from the side away from the door side wall 32 to the direction away from the door front wall 31 and close to the door side wall 32 , and then extends to the side close to the door front wall 31 and the door side wall 32 .

[0163] The guide track line S is located on a side of the guide track line K close to the first side edge W.

[0164] The guide track line K includes a first guide section and a second guide section connected to an end of the first guide section close to the door side wall 32. The first guide section extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and away from the door front wall 31. The second guide section extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and the door front wall 31.

[0165] In some embodiments of the present application, when the door body 30 is in a closed state, the second axis 42 is located on a side of the first axis 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.

[0166] Since the guide portion 50 and the first shaft 41, and the guide portion 60 and the second shaft 42 are in a relative motion relationship, 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 convenience of description, the present application adopts 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 description.

[0167] 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 15 , Figure 17-Figure 30 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 distance inward (in the direction close to the second body side wall) 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.

[0168] Under the above settings, during the process of the door body 30 opening, the first axis 41 moves relative to the guide part 50 throughout the entire process, the second axis 42 moves relative to the guide part 60 throughout the entire process, and the door body 30 rotates around the point (axis center point I) that maintains dynamic changes relative to the door body 30 throughout the entire process. Under the above settings, during the process of the door body 30 opening, the first center axis P moves relative to the guide trajectory line S, and the second center axis Q moves relative to the guide trajectory line K, and they rotate with the axis center point I as the instantaneous rotation center, and the instantaneous rotation center of the door body 30 is the axis center point I. The position of the axis center point I relative to the door body 30 is constantly changing, and the position of the instantaneous rotation center of the door body 30 is constantly changing.

[0169] 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 first center axis P of the rotational motion, rather than the axis center point I.

[0170] The movement of the door body 30 relative to the box body 10 is equivalent to the relative movement of the two in the plane where the top wall of the box body 10 is located (or in the plane perpendicular to the first side edge W or the second side edge N). That is, the movement of the door body 30 relative to the box body 10 can be attributed to the relative movement in a two-dimensional plane.

[0171] 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, in 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.

[0172] In the following description, for the convenience of explanation, the movement of the axis line segment PQ relative to the second hinge member (the guide portion 50 and the guide portion 60) provided on the door body 30 in the plane where the top wall of the box body 10 is located is selected to represent the movement of the box body 10 relative to the door body 30. That is, the description of the relative movement of the present invention is described as the relative movement in a two-dimensional plane.

[0173] Indicates the opening angle of the door body 30. When the door body 30 is in a closed state, the opening angle of the door body 30 is recorded as the closing angle G G .

[0174] In some embodiments of the present application, The door front wall 31 is parallel to the plane where the access opening is located.

[0175] In some embodiments of the present application, The door rear wall 33 is perpendicular to the plane where the access opening is located.

[0176] In some embodiments of the present application, The door side wall 32 is parallel to the plane where the access opening is located.

[0177] The door body 30 is relative to the box body 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.

[0178] 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.

[0179] The hinge assembly having the extension trend and relative position characteristics of the guide track line S and the guide track line K guides the door body 30 to open. Figure 2 to Figure 31 As shown, the door body 30 opening process includes the following stages:

[0180] The door body is at the first stage angle G J1 Open to the second stage angle G J2 During the process, the first axis moves toward a side close to the door front wall and the door side wall, and the second axis moves away from the door front wall and close to the door side wall;

[0181] The door body is at the second stage angle G J2 Open to the third stage angle G J3 During the process, the first axis moves toward a side away from the door front wall and the door side wall, and the second axis moves toward a side away from the door front wall and close to the door side wall;

[0182] The door body is at the third stage angle G J3 Open to the fourth stage angle G J4 During the process, the first axis moves toward a side close to the door front wall and the door side wall, and the second axis moves away from the door front wall and close to the door side wall;

[0183] The door body is at the fourth stage angle G J4 Open to the fifth stage angle G J5 During the process, the first axis moves toward the side close to the door front wall and the door side wall, and the second axis moves toward the side close to the door front wall and the door side wall;

[0184] The door body is at the fifth stage angle G J5 Open to the sixth stage angle G J6 During the process, the first axis moves toward a side away from the door front wall and the door side wall, and the second axis moves toward a side close to the door front wall and the door side wall;

[0185] Among them, G J1 <G J2 <G J3 <G J4 <G J5 <G J6 The refrigerator with the hinge assembly having the above characteristics allows the door body to not interfere with the storage cabinet when opening, and allows the door body to be opened to a larger angle in the storage cabinet, so that the door body can be fully opened in the storage cabinet, making it convenient for users to take and put items.

[0186] like Figure 1 to Figure 1 As shown in FIG. 6 , in some embodiments of the present application, the guide track line S is a curve. The guide track line S is convex toward the side close to the second side edge N.

[0187] In some embodiments of the present application, the guide groove is a curved groove. The guide groove is a curved groove.

[0188] 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 access 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.

[0189] β is not less than a first reference value. The first reference value is between 65° and 74°. The first reference value may be 65°, 70° or 74°. That is, β≥65° or β≥70° or β≥74°.

[0190] 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. When β≥74°, the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30.

[0191] β is not greater than a second reference value. The second reference value is between 77° and 86°. The second reference value may be 77°, 81°, or 86°. That is, β≤77° or β≤81° or β≤86°.

[0192] When β≤77°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are better met. When β≤81°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are better met. When β≤86°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are met.

[0193] 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 door front wall 31 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 dimension 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 an ultra-thin door body 30.

[0194] β is too large, 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 small; the guide portion 50 and the guide portion 60 are arranged too compactly. In order to avoid the guide portion 60 of the guide portion 50 not being cross-connected, as a way, 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, and the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly. Reducing the diameter of the first shaft 41 and the second shaft 42 reduces the strength of the first shaft 41 and the second shaft 42, which can easily cause the hinge assembly to be damaged and fail. As another way, the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure their strength, and 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.

[0195] In some embodiments of the present application, the guide track line K includes a first guide segment and a second guide segment connected to an end of the first guide segment close to the door side wall 32. The first guide segment extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and away from the door front wall 31, and the second guide segment extends from an end of the first guide segment close to the door side wall to a direction close to the door side wall 32 and the door front wall 31. That is, the second guide segment extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and the door front wall 31.

[0196] In some embodiments of the present application, Figure 2 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 opposite end of the door side wall 32 on the door body 30 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.

[0197] 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).

[0198] The first derivative of Y = F(X) is denoted by F` x , F`x > 0. Y = F (X) is a monotonically increasing function.

[0199] 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 function.

[0200] In some embodiments of the present application, in the door body coordinate system XOY, the function corresponding to the guide trajectory line K in the coordinate system XOY is recorded as Y=K(X); Y=K(X) is a piecewise function, and the piecewise function is a continuous function; then, at each segment point, its left limit is equal to its right limit.

[0201] In some embodiments of the present application, in the door body coordinate system XOY, Y=K(X) is as follows:

[0202]

[0203] Among them, X 1 >X 2 >X 3 >0;K 1 (X 2 )=K 2 (X 2 );

[0204] Y=K 1 (X) is a function of the second guide segment in the coordinate system XOY;

[0205] Y=K 2 (X) is a function of the first guide segment in the coordinate system XOY.

[0355] The guiding trajectory line K is from the seventh guiding point Q 7 Extends to the side close to the door front wall 31 to the eighth guide point Q 8 .

[0356] The door body 30 is formed at the seventh angle G 7 Open to the eighth angle G 8 During the process, the first central axis P moves toward a side away from the door front wall 31 and the door side wall 32 .

[0365] Specifically, the door body 30 is formed by the seventh angle G 7 Open to the eighth angle G 8 During the process, the first central axis P is formed by the seventh guide point P 7 Move along the guidance trajectory S to the eighth guidance point P 8 The second central axis Q is from the seventh guide point Q 7 Move along the guide track line K to the eighth guide point Q 8 .

[0366] 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 ).

[0367] The door body 30 is formed at the seventh angle G 7 Open to the eighth angle G 8 In the process, the axis line segment PQ is P 7 Q 7 Rotate clockwise and move to P 8 Q 8 The movement trend of the axis line segment PQ is P 7 Q 7 →P 8 Q 8 At the same time, the movement trend of the axis center point I moving along the axis line segment PQ is I 7 →I 8 That is, during the opening process of the door body 30 , the center point I of the axis moves toward the side away from the door front wall 31 and close to the door side wall 32 relative to the door body 30 .

[0368] Since the guide part 50 and the guide part 60 are arranged on the door body 30, the axis line segment PQ represents the movement of the hinge plate 40 arranged on the box body 10. It is concluded that: taking the door body 30 as a reference, the door body 30 is moved from the seventh angle G 7 Open to the eighth angle G 8 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 to the side away from the door front wall 31 and close to the door side wall 32.

[0369] In summary, the door body 30 is at the seventh angle G 7 Open to the eighth angle G 8 In the process, with the door body 30 (guide groove / guiding groove) as a reference, the box body 10 has a translational motion while rotating relative to the door body 30. The translational motion is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the door side wall 32 side and a displacement parallel to the door side wall 33 and pointing away from the door front wall 31 side.

[0370] According to the relativity of motion, taking the box 10 as a reference, the door 30 is at the seventh angle G 7 Open to the eighth angle G 8 During the process, the door body 30 has a translational movement while rotating. The translational movement is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0371] In some embodiments of the present application, the first guiding point P 1 , the second guiding point P 2 , the third guiding point P 3 , the fourth guiding point P 4 , the fifth guiding point P 5 , the sixth guiding point P 6 , the seventh guiding point P 7 , the eighth guiding point P 8 Located on the guide trajectory S.

[0372] 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.

[0373] In some embodiments of the present application, the first guiding point P 1 With the seventh guide point P 7 The straight line is called straight line P 1 P 7 ; Line P 1 P 7 The angle between the door and the front wall 31 is denoted as λ;

[0374] Wherein, λ is not less than the first angle reference value; the first angle reference value is between 32° and 38°. The first angle reference value may be 32°, 35° or 38°. That is, λ≥32° or λ≥35° or λ≥38°.

[0375] When λ≥32°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are met. When λ≥35°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are better met. When λ≥38°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are better met.

[0376] λ is not greater than the second angle reference value; the second angle reference value is 40° to 46°. The first angle reference value may be 40°, 43° or 46°. That is, λ≤40° or λ≤43° or λ≤46°.

[0377] When λ≤40°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When λ≤43°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When λ≤46°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is met.

[0378] λ is too large, resulting in the wall thickness between the guide part 50 and the guide part 60 being too thin, reducing the strength of the guide part 50 and the guide part 60. In addition, when the distance between the end of the guide part 50 away from the door side wall 31 and the door front wall 31 is relatively large, the size of the guide part 60 in the direction perpendicular to the door front wall 31 increases synchronously, and the size of the overall trajectory of the guide part 50 and the guide part 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 on ultra-thin refrigerators. Furthermore, the thickness of the door body 30 is too large, resulting in an increase in the obstruction of the door body 30 to the access port; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the lateral width of the drawer, resulting in the drawer being unable to effectively utilize the lateral space of the storage room.

[0379] If λ is too small, there will be insufficient space for screws (not limited to screw fixing, any conventional fixing method that can fix two parts) between the two tracks of the guide part 50 and the guide part 60 on the mounting block. In order to meet the fixing requirements, it is necessary to increase the area of ​​the mounting block; 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 front wall 31 of the door to increase the position for screws (not limited to screw fixing, any conventional fixing method that can fix two parts). The increase in the size of the mounting block in the direction perpendicular to the front wall 31 of the door will increase the thickness of the door body 30 that matches it, affecting its use on ultra-thin refrigerators. Furthermore, the thickness of the door body 30 is too large, resulting in an increase in the obstruction of the door body 30 to the access port; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the lateral width of the drawer, resulting in the drawer being unable to effectively utilize the lateral space of the storage room.

[0380] In some embodiments of the present application, the door body 30 is at a first angle G 1 Open to the eighth angle G 8 During the process, the door body 30 is opened to the first angle G 1 When the first central axis P is located at the first guiding point P of the guiding trajectory line S 1 On the guiding trajectory S, the first guiding point P 1 The distance from the door side wall 32 is the largest. On the guide trajectory line S, the first guide point P 1 The distance from the door front wall 31 is the largest.

[0381] In some embodiments of the present application, the door body 30 is at a first angle G 1 Open to the eighth angle G 8 During the process, the door body 30 is opened to the seventh angle G 7 When the first central axis P is located at the seventh guide point P of the guide trajectory line S 7 On the guidance trajectory line S, the seventh guidance point P 7 The distance from the door side wall 32 is the smallest. On the guide trajectory line S, the seventh guide point P 7 The distance from the door front wall 31 is the smallest.

[0382] In some embodiments of the present application, the guide trajectory line S is formed by the first guide point P 1 Extending to the side close to the door side wall 32 to the seventh guide point P 7 .

[0385] In some embodiments of the present application, the first angle G 1 <Second angle G 2 <Third angle G 3 <Fourth angle G 4 =90°<Fifth Angle G 5 <Sixth angle G 6 <Seventh Angle G 7 <Eighth Angle G 8 .

[0386] In some embodiments of the present application, the door body 30 is opened to G 4 =90°, the door front wall 31 is flush with the first body side wall. "Flush" includes the situation where the distance between the two planes of the door front wall 31 and the first body side wall is not greater than 3 mm.

[0387] In some embodiments of the present application, the first guide point Q 1 , the second guide point Q 2 、The third guide point Q 3 、The fourth guide point Q 4 、Fifth guide point Q 5 、The sixth guide point Q 6 、Seventh guide point Q 7 、The eighth guiding point Q 8 Located on the guide trajectory line K.

[0388] In some embodiments of the present application, the guide trajectory line K is formed by the first guide point Q 1 Extends to the side close to the door side wall 32 to the eighth guide point Q 8 .

[0389] The guiding trajectory K is from the first guiding point Q 1 First, extend to the side away from the door front wall 31 to the sixth guide point Q 6 , and then from the sixth guide point Q 6 Extend to the side close to the door front wall 31 to the seventh guide point Q 7 Then, the seventh guide point Q 7 Extending to the side away from the door front wall 31 to the eighth guide point Q 8 .

[0390] The guiding trajectory K is from the first guiding point Q1 Passing the second guide point Q 2 、The third guide point Q 3 、The fourth guide point Q 4 、Fifth guide point Q 5 、The sixth guide point Q 6 、Seventh guide point Q 7 Extend to the eighth guide point Q 8 .

[0391] In some embodiments of the present application, the guide trajectory line K is firstly 1 Extending to the side away from the door front wall 31 and close to the door side wall 32 to the sixth guide point Q 6 , and then from the sixth guide point Q 6 Extend to the side close to the door front wall 31 and the door side wall 32 to the seventh guide point Q 7 Then, the seventh guide point Q 7 The side away from the door front wall 31 and close to the door side wall 32 extends to the eighth guide point Q 8 .

[0392] Along the direction from the end of the door body 30 away from the door side wall 32 to the door side wall 32, the distance between the guide track line K and the door front wall 31 first increases, then decreases, and then increases again.

[0393] In some embodiments of the present application, the eighth guide point Q 8 Located at the sixth guide point Q 6 Close to the door side wall 32 and the door front wall 31.

[0394] Sixth guide point Q 6 It is the point where the distance between the guide trajectory line K and the door front wall 31 is the largest.

[0395] In some embodiments of the present application, the first guiding point P 1 Located at the first guide point Q 1 Close to the door rear wall 33 and the door side wall 32. The sixth guide point P 6 Located at the sixth guide point Q 6 One side close to the door front wall 31 and the door side wall 32. The eighth guide point P 8 Located at the eighth guide point Q 8 A side close to the door front wall 31 and away from the door side wall 32.

[0396] Combining the first stage, the second stage, the third stage, the fourth stage and the fifth stage, it can be seen that: the door body 30 is at the first angle G 1 Open to the eighth angle G 8 During the opening process, the first shaft 41 first moves toward the direction close to the door front wall 31 and the door side wall 32 (G 1 ~G 2), and then moves in the reverse direction away from the door front wall 31 and the door side wall 32 (G 2 ~G 3 ), and then moves in the opposite direction toward the door front wall 31 and the door side wall 32 (G 3 ~G 7 ), and then moves in the reverse direction away from the door front wall 31 and the door side wall 32 (G 7 ~G 8 ). In summary, the door body 30 is formed at the first angle G 1 Open to the eighth angle G 8 During the opening process, the first shaft 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 part 50 and fully utilizes the small-sized guide part 50 to complete the opening of the door body 30 at a large angle.

[0397] Combining the situations in the first, second, third, fourth and fifth stages, it can be seen 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 In different opening stages of the door body 30, the first direction displacement and the second direction displacement There will be different directions.

[0398] In summary, the movement process of the first central axis P and the second central axis Q of the door body 30 during the first stage to the fifth stage, and the movement trend of the synchronous axis center point I, can reveal the movement process of the axis center point I.

[0399] Specifically, Fig.15 As shown, the movement process of the axis center point I relative to the door body 30 includes a first axis trajectory segment.

[0400] The first axis track section: the door body 30 is at the first angle G 1 Open to the fifth angle G 5 During the process, the center point I of the axis moves away from the door front wall 31 and closer to the door side wall 32.

[0401] The axis center point I is from the second midpoint I 2 The side away from the door front wall 31 and close to the door side wall 32 passes through the third midpoint I 3 、The fourth midpoint I 4 Move to the fifth midpoint I 5 .

[0402] Taking the box body 10 as a reference, the door body 30 is at a first angle G 1 Open to the fifth angle G 5 During the process, the door body 30 has a translational movement while rotating. The translational movement is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0403] The door body 30 is formed by the first angle G 1 Open to the fifth angle G 5 During the process, the first direction displacement Pointing away from the door side wall 32, the second direction displacement Point to the side of the door front wall 31.

[0404] In some embodiments of the present application, the fifth angle G 5 The difference from 90° is recorded as ΔG 5 ;

[0405] Among them, ΔG 5 is not less than the first reference difference; the first reference difference is between 0° and 2°. The first reference difference can be 0°, 1° or 2°. That is, ΔG 5 ≥0° or ΔG 5 ≥1° or ΔG 5 ≥2°.

[0406] ΔG 5 When ≥0°, the door body 30 meets the requirement of shielding the access opening. ΔG 5 When ΔG is ≥1°, the requirement of the door body 30 to block the access opening is better met. 5 When the angle is ≥2°, the requirement of the door body 30 to shield the access opening is better met.

[0407] ΔG 5 is not greater than the second reference difference; the second reference difference is between 3° and 6°. The second reference difference can be 3°, 4° or 6°. That is, ΔG 5 ≤3° or ΔG 5 ≤4° or ΔG 5 ≤6°.

[0408] ΔG 5 When ΔG is ≤3°, the maximum opening angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 can be better met. 5 When ΔG is ≤4°, the maximum angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 can be better met. 5 When ≤6°, the maximum opening angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 is met.

[0409] Among them, ΔG 8 If the angle is too small, after the door body 30 is opened to 90°, the displacement of the door body 30 moving outward 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.

[0410] ΔG 5 If the angle of the door body 30 is too large, after the door body 30 is opened to 90°, the outward displacement is too large, and the distance between the door body 30 and the storage cabinet 100 is too close. The maximum opening angle of the door body 30 of the refrigerator placed in the storage cabinet 100 is reduced, which is not conducive to the door body 30 being opened to a larger angle, and is especially inconvenient for users to take and put items placed on the inside of the door body 30.

[0411] like Fig.15 As shown, the movement process of the axis center point I relative to the door body 30 includes a second axis trajectory segment.

[0412] Second axis track segment: the door body 30 is at the fifth angle G 5 Open to the seventh angle G 7 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.

[0413] The axis center point I is from the fifth midpoint I 5 Towards the side close to the door front wall 31 and the door side wall 32 through the sixth midpoint I 6 Move to the seventh midpoint I 7 .

[0414] Taking the box body 10 as a reference, the door body 30 is at the fifth angle G 5 Open to the seventh angle G 7 During the process, the door body 30 has a translational movement while rotating. The translational movement is specifically: 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.

[0415] The door body 30 is formed by a fifth angle G 5 Open to the seventh angle G 7 During the process, the first direction displacement Pointing away from the door side wall 32, the second direction displacement It points to the side away from the front wall 31 of the door.

[0416] like Fig.15 As shown, the movement process of the axis center point I relative to the door body 30 includes a third axis trajectory segment.

[0417] The third axis track segment: the door body 30 is at the seventh angle G 7 Open to the eighth angle G 8During the process, the center point I of the axis moves away from the door front wall 31 and closer to the door side wall 32.

[0418] The axis center point I is from the seventh midpoint I 7 Move to the side away from the door front wall 31 and close to the door side wall 32 to the eighth midpoint I 8 .

[0419] Taking the box body 10 as a reference, the door body 30 is at the seventh angle G 7 Open to the eighth angle G 8 During the process, the door body 30 has a translational movement while rotating.

[0496] In some embodiments of the present application, the door body 30 is formed by the seventh angle G 7 Open to the eighth angle G 8 During the opening and closing process, the door body 30 has a tendency to move outward and forward, so that when the refrigerator is not placed in the storage cabinet 100, the door body 30 can be opened to a larger angle while reducing the obstruction of the door body to the access opening.

[0497] In some embodiments of the present application, The door body 30 is formed at the seventh angle G 7 Open to the eighth angle G 8 During the process, the door body 30 mainly moves outward, while there is a tendency to move forward a small amount; when the refrigerator is not placed in the storage cabinet 100, the door body 30 can be opened to a larger angle while reducing the obstruction of the door body to the access port.

[0498] 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 the B-axis throughout the process of rotating and opening.

[0499] In some embodiments of the present application, the guide trajectory line K extends from the side away from the door side wall 32 first toward the direction away from the door front wall 31 and close to the door side wall 32, then extends to the side close to the door front wall 31 and the door side wall 32, and then extends away from the door front wall 31 and close to the door side wall 32.

[0500] The guide track line K includes a first guide section, a second guide section connected to an end of the first guide section close to the door side wall 32, and a third guide section connected to an end of the second guide section close to the door side wall 32. The first guide section extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and away from the door front wall 31. The second guide section extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and the door front wall 31. The third guide section extends from an end away from the door side wall 32 to a direction close to the door side wall 32 and away from the door front wall 31.

[0501] The difference between the above guide track line K including the first guide segment and the second guide segment is that the door body 30 includes a sixth stage during the opening process, and the door body 30 is opened from the eighth angle G 8 When the door continues to open, the first shaft 41 moves relative to the guide portion 50 to a side away from the door side wall 32 and the door front wall 31 , and the second shaft 42 moves relative to the guide portion 60 to a side close to the door side wall 32 and away from the door front wall 31 .

[0502] The center point I of the axis moves toward the door side wall 32 and away from the door front wall 31 .

[0503] Figure 17 to Figure 3 2 is a schematic diagram of another implementation of the refrigerator of the utility model, wherein the guide track line S is a straight line.

[0504] In some embodiments of the present application, Fig.17 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.

[0505] In some embodiments of the present application, in the projection of the top wall of the box 10, the second central axis Q is located on the side of the first central axis P away from the first body side wall and the access opening. The angle between the second central axis Q and the straight line QP where the first central axis P is located and the first body side wall is denoted as β.

[0506] β is not less than a first reference value. The first reference value is between 63° and 73°. The first reference value may be 63°, 68° or 73°. That is, β≥63° or β≥68° or β≥73°.

[0507] When β≥63°, the requirement that the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30 is met. When β≥68°, the requirement that the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30 is better met. When β≥73°, the requirement that the guide portion 50 and the guide portion 60 occupy a small thickness of the door body 30 is better met.

[0508] β is not greater than a second reference value. The second reference value is between 74° and 84°. The second reference value may be 74°, 79° or 84°. That is, β≤74° or β≤79° or β≤84°.

[0509] When β≤74°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are better met. When β≤79°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are better met. When β≤84°, the strength requirements of the guide parts 50 and 60, the first shaft 41 and the second shaft 42 are met.

[0510] 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 door front wall 31 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 dimension 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 an ultra-thin door body 30.

[0511] β is too large, 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 small; the guide portion 50 and the guide portion 60 are arranged too compactly. In order to avoid the guide portion 60 of the guide portion 50 not being cross-connected, as a way, 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, and the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly. Reducing the diameter of the first shaft 41 and the second shaft 42 reduces the strength of the first shaft 41 and the second shaft 42, which can easily cause the hinge assembly to be damaged and fail. As another way, the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure their strength, and 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.

[0516] 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 to the door side wall 32 , a distance between the guide track line S and the door front wall 31 gradually decreases.

[0517] Along the direction from the end of the door body 30 away from the door side wall 32 to the door side wall 32, the distance between the guide track line K and the door front wall 31 first increases, then decreases, and then increases again.

[0518] 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 .

[0700] Wherein, γ is not less than the first angle reference value; the first angle reference value is between 27° and 37°. The first angle reference value may be 27°, 32° or 37°. That is, γ≥27° or γ≥32° or γ≥37°.

[0701] When γ≥27°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are met. When γ≥32°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are better met. When γ≥32°, the fixing space requirement of the mounting block and the small thickness of the door body 30 occupied by the mounting block are better met.

[0702] γ is not greater than the second angle reference value; the second angle reference value is between 38° and 48°. The second angle reference value may be 38°, 43° or 48°. That is, γ≤38° or γ≤43° or γ≤48°.

[0703] When γ≤38°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When γ≤43°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is better met. When γ≤48°, the wall thickness requirement between the guide portion 50 and the guide portion 60 is met.

[0704] γ is too large, resulting in the wall thickness between the guide part 50 and the guide part 60 being too thin, reducing the strength of the guide part 50 and the guide part 60. In addition, when the distance between the end of the guide part 50 away from the door side wall 31 and the door front wall 31 is relatively large, the size of the guide part 60 in the direction perpendicular to the door front wall 31 increases synchronously, and the size of the overall trajectory of the guide part 50 and the guide part 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 on ultra-thin refrigerators. Furthermore, the thickness of the door body 30 is too large, resulting in an increase in the obstruction of the door body 30 to the access port; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the lateral width of the drawer, resulting in the drawer being unable to effectively utilize the lateral space of the storage room.

[0705] If γ is too small, there will be insufficient space for screws (not limited to screw fixing, any conventional fixing method that can fix two parts) between the two tracks of the guide part 50 and the guide part 60 on the mounting block. In order to meet the fixing requirements, it is necessary to increase the area of ​​the mounting block; 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 front wall 31 of the door to increase the position for screws (not limited to screw fixing, any conventional fixing method that can fix two parts). The increase in the size of the mounting block in the direction perpendicular to the front wall 31 of the door will increase the thickness of the door body 30 that matches it, affecting its use on ultra-thin refrigerators. Furthermore, the thickness of the door body 30 is too large, resulting in an increase in the obstruction of the door body 30 to the access port; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the lateral width of the drawer, resulting in the drawer being unable to effectively utilize the lateral space of the storage room.

On the guide trajectory line S, the first guide point P 1 The distance from the door front wall 31 is the largest.

[0707] In some embodiments of the present application, the door body 30 is at a first angle G 1Open to the ninth angle G 9 During the process, the door body 30 is opened to the eighth angle G 8 When the first central axis P is located at the eighth guiding point P of the guiding trajectory line S 8 On the guiding trajectory line S, the eighth guiding point P 8 The distance from the door side wall 32 is the smallest. On the guide trajectory line S, the eighth guide point P 8 The distance from the door front wall 31 is the smallest.

[0711] In some embodiments of the present application, the first angle G 1 <Second angle G 2 <Fourth angle G 4 =90°<Fifth Angle G 5 <Sixth angle G 6 <Seventh Angle G 7 <Eighth Angle G 8 <9th Angle G 9 .

[0712] In some embodiments of the present application, the first guide point Q 1 , the second guide point Q 2 、The third guide point Q 3 、The fourth guide point Q 4 、Fifth guide point Q 5 、The sixth guide point Q 6 、Seventh guide point Q 7 、The eighth guiding point Q 8 、The ninth guiding point Q 9 Located on the guide trajectory line K.

[0713] In some embodiments of the present application, the guide trajectory line K is formed by the first guide point Q 1 Extends to the side close to the door side wall 32 to the ninth guide point Q 9 .

[0714] The guiding trajectory K is from the first guiding point Q 1 First, extend to the side away from the door front wall 31 to the seventh guide point Q 7 , and then from the seventh guide point Q 7 Extends to the side close to the door front wall 31 to the eighth guide point Q 8 Then, the eighth guide point Q 8 Extending to the side away from the door front wall 31 to the ninth guide point Q 9 .

[0715] The guiding trajectory K is from the first guiding point Q 1 Passing the second guide point Q 2 、The third guide point Q 3 、The fourth guide point Q 4 、Fifth guide point Q 5 、The sixth guide point Q 6 、Seventh guide point Q 7 、The eighth guiding point Q 8 Extend to the ninth guide point Q 9 .

[0716] In some embodiments of the present application, the guide trajectory line K is firstly 1 Extending to the side away from the door front wall 31 and close to the door side wall 32 to the seventh guide point Q 7 , and then from the seventh guide point Q 7 Extend to the side close to the door front wall 31 and the door side wall 32 to the eighth guide point Q 8 Then, the eighth guide point Q 8 The side away from the door front wall 31 and close to the door side wall 32 extends to the ninth guide point Q 9 .

[0717] Along the direction from the end of the door body 30 away from the door side wall 32 to the door side wall 32, the distance between the guide track line K and the door front wall 31 first increases, then decreases, and then increases again.

[0718] In some embodiments of the present application, the ninth guide point Q 9 Located at the seventh guide point Q 7 Close to the door side wall 32 and the door front wall 31.

[0719] Seventh guide point Q 7 It is the point where the distance between the guide trajectory line K and the door front wall 31 is the largest.

[0720] In some embodiments of the present application, the first guiding point P 1 Located at the first guide point Q 1 Close to the door rear wall 33 and the door side wall 32. The seventh guide point P 7 Located at the seventh guide point Q 7 The side close to the door front wall 31 and the door side wall 32. The ninth guide point P 9 Located at the ninth guide point Q 9 A side close to the door front wall 31 and away from the door side wall 32.

[0721] Combining the first stage, the second stage, the third stage, the fourth stage and the fifth stage, it can be seen that: the door body 30 is at the first angle G 1 Open to the ninth angle G 9 During the opening process, the first shaft 41 first moves toward the direction close to the door front wall 31 and the door side wall 32 (G 1 ~G 3 ), and then moves in the reverse direction away from the door front wall 31 and the door side wall 32 (G 3 ~G 5 ), and then moves in the opposite direction toward the door front wall 31 and the door side wall 32 (G 5 ~G 8 ), and then moves in the reverse direction away from the door front wall 31 and the door side wall 32 (G 8 ~G 9 ). In summary, the door body 30 is formed at the first angle G 1 Open to the ninth angle G 9 During the opening process, the first shaft 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 part 50 and fully utilizes the small-sized guide part 50 to complete the opening of the door body 30 at a large angle.

[0722] Combining the situations in the first, second, third, fourth and fifth stages, it can be seen 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 In different opening stages of the door body 30, the first direction displacement and the second direction displacement There will be different directions.

[0723] In summary, the movement process of the first central axis P and the second central axis Q of the door body 30 during the first stage to the fifth stage, and the movement trend of the synchronous axis center point I, can reveal the movement process of the axis center point I.

[0724] Specifically, Fig.31 As shown, the movement process of the axis center point I relative to the door body 30 includes a first axis trajectory segment.

[0725] The first axis track section: the door body 30 is at the first angle G 1 Open to the second angle G 2 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.

[0726] The axis center point I is the first midpoint I 1 Move to the side close to the door front wall 31 and the door side wall 32 to the second midpoint I 2 .

[0727] Taking the box body 10 as a reference, the door body 30 is at a first angle G 1 (Configurable, G G =G 1 or G G =G 1 =0°) open to the second angle G 2 During the process, the door body 30 has a translational movement while rotating. The translational movement is specifically: 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.

[0728] The door body 30 is formed by the first angle G 1 (Configurable, G G =G 1 or G G =G 1 =0°) open to the second angle G 2 During the process, the first direction displacement Pointing away from the door side wall 32, the second direction displacement It points to the side away from the front wall 31 of the door.

[0729] like Fig.31 As shown, the movement process of the axis center point I relative to the door body 30 includes a second axis trajectory segment.

[0730] The second axis track segment: the door body 30 is at the second angle G 2 Open to the sixth angle G 6 During the process, the center point I of the axis moves away from the door front wall 31 and closer to the door side wall 32.

[0731] The axis center point I is from the second midpoint I 2 The side away from the door front wall 31 and close to the door side wall 32 passes through the third midpoint I 3 、The fourth midpoint I 4 、Fifth midpoint I 5 Move to the sixth midpoint I 6 .

[0732] Taking the box body 10 as a reference, the door body 30 is at a second angle G 2 Open to the sixth angle G 6 During the process, the door body 30 has a translational movement while rotating. The translational movement is specifically: relative to the door body 30, the box body 10 has a displacement parallel to the door rear wall 33 and pointing to the side away from the door side wall 32 and a displacement parallel to the door side wall 33 and pointing to the door front wall 31.

[0737] ΔG 6 is not greater than the second reference difference; the second reference difference is between 5° and 7°. The second reference difference can be 5°, 6° or 7°. That is, ΔG 6 ≤5° or ΔG 6 ≤6° or ΔG 6 ≤7°.

[0738] ΔG 6When ΔG is ≤5°, the maximum angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 can be better met. 6 When ΔG is ≤6°, the maximum angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 can be better met. 6 When ≤7°, the maximum opening angle requirement of the door 30 of the refrigerator placed in the storage cabinet 100 is met.

[0739] Among them, ΔG 6 If the angle is too small, after the door body 30 is opened to 90°, the displacement of the door body 30 moving outward 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.

[0740] ΔG 6 If the angle of the door body 30 is too large, after the door body 30 is opened to 90°, the outward displacement is too large, and the distance between the door body 30 and the storage cabinet 100 is too close. The maximum opening angle of the door body 30 of the refrigerator placed in the storage cabinet 100 is reduced, which is not conducive to the door body 30 being opened to a larger angle, and is especially inconvenient for users to take and put items placed on the inside of the door body 30.

[0741] like Fig.31 As shown, the movement process of the axis center point I relative to the door body 30 includes a third axis trajectory segment.

[0745] The door body 30 is formed by the sixth angle G 6 Open to the eighth angle G 8 During the process, the first direction displacement Pointing away from the door side wall 32, the second direction displacement It points to the side away from the front wall 31 of the door.

[0746] like Fig.31 As shown, the movement process of the axis center point I relative to the door body 30 includes a fourth axis trajectory segment.

[0747] The fourth axis track segment: the door body 30 is at the eighth angle G 8 Open to the ninth angle G 9 During the process, the center point I of the axis moves away from the door front wall 31 and closer to the door side wall 32.

[0748] The axis center point I is from the eighth midpoint I 8 Move to the side away from the door front wall 31 and close to the door side wall 32 to the ninth midpoint I 9 .

[0749] Taking the box body 10 as a reference, the door body 30 is at the eighth angle G 8 Open to the ninth angle G 9 During the process, the door body 30 has a translational movement while rotating.

[0752] The door 30 is opened, and the center point I of the axis moves. 1 =G J1 <G 2 <G J2 <G 4 =90°<G J3 <G 6 <G J4 <G 8 =G J5 <G 9 =G J6 .

[0753] 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 ;

[0757] In addition, it should be noted that the first direction displacement Second direction displacement All of them are instantaneous relative translation displacements, to illustrate the instantaneous translation movement trend of the door body 30 relative to the box body 10.

[0758] See also Figure 32a-32h As shown, 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 Displacement in the first direction 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

In the plane where the top wall of the box body 10 is located, along 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 side wall 32 extends outward and forward; 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 inward and forward.

[0760] In the above opening process (the first angle G 1 (Configurable, G G =G 1 or GG =G 1 =0°) open to G 4 =90°), the door side wall 32 is aligned with the reference plane M 0 The door side wall 32 and the plane where the access port is located start to rotate counterclockwise from the parallel state, and 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 M 0 The angle between them gradually increases; that is, when the door body 30 is at the first angle G 1 (Configurable, G G =G 1 or G G =G 1 =0°) to G 4 =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 door rear wall 33 and the reference plane M 0 The angle between them gradually decreases; that is, when the door body 30 is at the first angle G 1 (Configurable, G G =G 1 or G G =G 1 =0°) to G 4 =90° opening process, 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 access opening (close to the second body side wall and away from the access opening).

[0761] (1.1) During the opening process of the door body 30, the door body 30 includes a first angle G corresponding to the first axis track segment. 1 (Configurable, G G =G 1 or G G =G 1 =0°) open to the second angle G 2 process.

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 moves from the second angle G 2 Open to the fourth angle G 4 =90°, the door body 30 rotates and opens relative to the box body 10 and has a tendency to move forward in translation.
