Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and 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, the standard 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 is adapted to the size of the storage cabinet, and a hidden flush installation is achieved. Under 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 opens to the extreme position. In summary, the extreme angle that the refrigerator door installed in the storage cabinet can be opened is limited by the size of the storage cabinet for realizing the hidden installation of the refrigerator and the gap between the outer wall of the refrigerator and the inner wall of the storage cabinet. The extreme angle that the refrigerator door installed in the storage cabinet can be opened is small, which is inconvenient for users to take and put items. Summary of the invention

[0094] Hereinafter, embodiments of the present application will be described in detail with reference to the accompanying drawings. In the accompanying drawings, a side of the refrigerator facing a user when in use is defined as a front side, and a side opposite thereto is defined as a rear side.

[0095] Reference Figure 1 The refrigerator includes a housing 10 having a storage chamber.

[0096] In some embodiments of the present application, the box body 10 defines a plurality of storage chambers for storing items. A take-out opening is formed at the front end of the storage chamber to place food into the storage chamber or take food out of the storage chamber.

[0097] In some embodiments of the present application, the box body 10 is connected to a door body 30 for opening and closing the storage chamber.

[0098] In some embodiments of the present application, a rotatable door 30 is provided on the box body 10 to open or close the access opening of the storage chamber.

[0099] In some embodiments of the present application, the refrigerator has a refrigeration device that supplies cold air to the storage chamber to store items placed in the storage chamber at low temperatures.

[0100] In some embodiments of the present application, the door body 30 is rotatably connected to the box body 10 via a hinge assembly located at an upper portion and a hinge assembly located at a lower portion.

[0101] 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 cooperates with the second hinge component and can rotate relative to each other.

[0102] The box body 10 includes a first side wall and a second side wall (i.e., a left side wall and a right side wall of the box body 10) that are arranged opposite to each other; a first hinge is arranged on the box body 10 and close to the first side wall, and a second hinge is arranged at an end of the door body 30 close to the first hinge, and 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.

[0103] The door body 30 has a door front wall 31 away from the box body 10 when the door body 30 is closed, a door rear wall 33 arranged opposite to the door front wall 31, and a door side wall 32 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.

Similarly, in order to avoid opening the door body 30 to the maximum angle G max When too much force is applied and the guide door body 30 moves excessively (due to stress deformation and other factors), an extension section is set at the end of the guide trajectory line S away from the door front wall 31 or the end of the guide trajectory line K close to the door side wall 32 to reserve space for the above situation. When space is reserved at at least one of the two ends of the guide part 50 or the guide part 60, the starting guide point P0, the starting guide point Q0, the eighth guide point P8, and the eighth guide point Q8 are not the endpoints of the trajectory line where they are located. That is, the setting of the starting guide point P0, the starting guide point Q0, the eighth guide point P8, and the eighth guide point Q8 as the endpoints of the trajectory line where they are located is only an implementable method, which essentially corresponds to the positions of the two hinge axes (the first axis 41 and the second axis 42) when the door body 30 is closed or opened to the maximum angle (the eighth angle), and is not limited by the endpoints of the trajectory line where they are located.

[0247] In some embodiments of the present application, L3 is any value between 8 mm and 12 mm.

[0248] In some embodiments of the present application, L3 is any value between 0 mm and 12 mm.

[0249] In order to reduce the obstruction of the storage space (access opening) by the door body 30, the door body 30 is made as thin as possible, and the distance between the door front wall 31 and the first side wall of the box body 10 is as small as possible when the door is opened 90 degrees, so as to make the door body 30 closer to the storage cabinet 100.

[0250] However, the guide part 50 and the guide part 60 are arranged on the door body 30 , and the small thickness of the door body 30 is not conducive to the arrangement of the guide part 50 and the guide part 60 .

[0251] In addition, when the door body 30 is opened at an angle of 90°, the distance between the door front wall 31 and the first side wall of the box body 10 is too small, which limits the door body 30 of the refrigerator in the storage cabinet 100 to open at a larger angle, making it inconvenient for users to take and put items.

[0252] When the door body 30 is opened at an angle of 90°, the distance between the door front wall 31 and the first side wall of the box body 10 is too large, which will cause the door body 30 to block too much of the access opening. In order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the horizontal width of the drawer, resulting in the drawer not being able to effectively utilize the horizontal space of the storage room.

[0253] The above limitation on the maximum opening angle of the door body 30 in the storage cabinet 100 and the limitation on the distance between the door front wall 31 and the first side wall of the box body 10 when the door body 30 is opened to 90° effectively solve the contradictions among the thickness of the door body 30, the drawer placed in the storage room with a 90° door opening, and the layout design of the guide part 50 and the guide part 60, while taking into account the above three requirements.

[0254] In some embodiments of the present application, the refrigerator 10 is placed in the storage cabinet 100, and the maximum angle G that the door body 30 can open is max (=G8) is not less than 113°.

[0255] In some embodiments of the present application, the box 10 is placed in the storage cabinet 100, and the maximum angle G that the door body 30 can open is max It is between 115° and 125°.

[0256] In some embodiments of the present application, the box 10 is placed in the storage cabinet 100, and the maximum angle G that the door body 30 can open is max It is between 113° and 125°.

[0257] In some embodiments of the present application, when the door body 30 is opened to 90°, the distance between the door front wall 31 and the first body side wall is no more than 8 mm.

[0258] In some embodiments of the present application, when the door body 30 is closed, the door front wall 31 is flush with the end surface of the opening end of the storage cabinet 100 .

[0259] It should be noted that the above flush includes the situation where the distance between the end surface of the door front wall 31 and the opening end of the storage cabinet 100 is less than 2 mm.

[0260] In some embodiments of the present application, see Figure 5 As shown, the distance α' between the side wall of the refrigerator installed in the storage cabinet 100 and the inner wall of the storage cabinet 100 is greater than the distance between the door side wall 32 and the inner wall of the storage cabinet 100 when the door body 30 is closed; that is, α'>L1. When the door body 30 is closed, the door body 30 can effectively cover the refrigerator body, preventing the refrigerator body from bulging due to foaming and affecting the appearance.

[0261] In some embodiments of the present application, Figure 3-Figure 4The point where the distance between the end of the guide portion 50 (guide groove) away from the door side wall 32 and the door front wall 31 is the shortest is recorded as the first guide boundary point Z1, the point where the distance between the end of the guide portion 50 (guide groove) close to the door side wall 32 and the door front wall 31 is the shortest is recorded as the second guide boundary point Z2, and the point where the distance between the guide portion 50 (guide groove) and the door front wall 31 is the longest is recorded as the third guide boundary point Z3.

[0262] The first guide boundary point Z1, the second guide boundary point Z2, and the third guide boundary point Z3 are all located on the wall surface of the guide portion 50 (guide groove) for matching with the first shaft 41. For example, when the guide portion 50 is a guide groove, the above three guide boundary points are all located on the inner wall of the guide groove.

[0263] In some embodiments of the present application, the point where the distance between the end of the guide portion 60 (guide groove) away from the door side wall 32 and the door front wall 31 is the shortest is recorded as the first guide boundary point H1, the point where the distance between the end of the guide portion 60 (guide groove) close to the door side wall 32 and the door front wall 31 is the shortest is recorded as the second guide boundary point H2, and the point where the distance between the guide portion 60 (guide groove) and the door front wall 31 is the longest is recorded as the third guide boundary point H3.

[0264] The first guide boundary point H1, the second guide boundary point H2, and the third guide boundary point H3 are all located on the wall surface of the guide portion 60 (guide groove) for matching with the second shaft 42. For example, when the guide portion 60 is a guide groove, the above three guide boundary points are all located on the inner wall of the guide groove.

[0271] In some embodiments of the present application, the third guide boundary point Z3 is located on a side of the fourth guide point P4 away from the door front wall 31 .

[0272] In some embodiments of the present application, the straight line Z2P4 where the third guide boundary point Z3 and the fourth guide point P4 are located is perpendicular to the door front wall 31 .

[0273] In some embodiments of the present application, the distance between the third guide boundary point Z3 and the fourth guide point P4 is equal to the radius of the first axis 41 .

[0274] In some embodiments of the present application, the first guide boundary point H1 is located on the side of the starting guide point Q0 close to the door front wall 31 .

[0275] In some embodiments of the present application, the straight line H1Q0 where the first guide boundary point H1 and the starting guide point Q0 are located is perpendicular to the door front wall 31 .

[0276] In some embodiments of the present application, the distance between the first guide boundary point H1 and the starting guide point Q0 is equal to the radius of the second axis 42 .

[0277] In some embodiments of the present application, the second guide boundary point H2 is located on the side of the eighth guide point Q8 close to the door front wall 31 .

[0278] In some embodiments of the present application, the straight line H2Q8 where the second guide boundary point H2 and the eighth guide point Q8 are located is perpendicular to the door front wall 31 .

[0279] In some embodiments of the present application, the distance between the second guide boundary point H2 and the eighth guide point Q8 is equal to the radius of the second axis 42 .

[0280] In some embodiments of the present application, the third guide boundary point H3 is located on the side of the seventh guide point Q7 away from the door front wall 31 .

[0281] In some embodiments of the present application, the straight line H3Q6 where the third guide boundary point H3 and the seventh guide point Q7 are located is perpendicular to the door front wall 31 .

[0282] In some embodiments of the present application, the distance between the third guide boundary point H3 and the seventh guide point Q7 is equal to the radius of the second axis 42 .

[0283] It should be noted that the distance between the first guide boundary point Z1 and the starting positioning point P0 is equal to the radius of the first axis 41, the distance between the second guide boundary point Z2 and the eighth positioning point P8 is equal to the radius of the first axis 41, the distance between the third guide boundary point Z3 and the fourth guide point P4 is equal to the radius of the first axis 41, the distance between the first guide boundary point H1 and the starting guide point Q0 is equal to the radius of the second axis 42, the distance between the second guide boundary point H2 and the eighth guide point Q8 is equal to the radius of the second axis 42, and the distance between the third guide boundary point H3 and the sixth guide point Q4 is equal to the radius of the second axis 42. The "equal to" includes deviations caused by processing errors, etc.

[0284] It can be set that the above "equal" includes the case where the difference between the two equal objects is any value between 0 and 2 mm.

[0285] It should be noted that, under the premise that the door front wall 31 and the door side wall 32 are arranged perpendicularly, the direction perpendicular to the door front wall 31 is the same as the direction parallel to the door side wall 32, that is, Figure 2 The direction perpendicular to the door side wall 32 is the same as the direction parallel to the door front wall 31, that is, Figure 2 The direction of the X1 axis.

[0286] In the case where the door front wall 31 and the door side wall 32 are not arranged perpendicularly, the direction perpendicular to the door front wall 31 only indicates the distance in the direction perpendicular to the door front wall 31, and has no necessary connection with the door side wall 32. Similarly, the direction perpendicular to the door side wall 32 only indicates the distance in the direction perpendicular to the door side wall 32, and has no necessary connection with the door front wall 31.

[0287] In the direction perpendicular to the door side wall 32, the distance between the first guide boundary point Z1 and the third guide boundary point Z3 is recorded as the first guide side spacing E' P1 The distance between the third guide boundary point Z3 and the second guide boundary point Z2 is recorded as the second guide side spacing E' P2 The distance E between the first guide boundary point Z1 and the third guide boundary point Z3 is P1 The distance E' between the third guide boundary point Z3 and the second guide boundary point Z2 P2 The ratio is E` P1 :E` P2 .

[0288] In some embodiments of the present application, E' P1 :E` P2 is greater than the first guide side spacing ratio. For example, the first guide side spacing ratio is 0.6, 0.8, or 1.

[0289] In some embodiments of the present application, E'P1 :E` P2 is smaller than the second guide side spacing ratio. For example, the second guide side spacing ratio is 1.15, 1.2, or 1.25.

[0290] If E` P1 :E` P2 If the angle of the door 30 is too large, the distance the door body 30 moves inward and forward during opening is small, and the restriction of the storage cabinet 100 on the maximum opening angle of the door body 30 cannot be effectively reduced, which ultimately results in the refrigerator being unable to be opened to a larger angle in the storage cabinet 100 (such as the maximum opening angle is 90°, or 100°, and cannot be opened to a larger angle of 113°, 115°, 120°).

[0291] If E` P1 :E` P2 If the angle is too small, the first side edge W (door corner) will extend beyond the original position during the opening of the refrigerator, which may easily cause the first side edge W to interfere with the storage cabinet 100, and the door body 30 cannot be opened further. In order to allow the door body 30 to be opened to a larger angle in the storage cabinet 100, a larger gap needs to be reserved between the closed door body 30 and the storage cabinet 100 to avoid the first side edge W (door corner) from interfering with the storage cabinet 100. However, the larger gap reserved above causes the door body 30 to be unable to effectively cover the cabinet 10, affecting the overall appearance of the refrigerator.

[0292] The first trajectory line S of the present invention is obtained by optimizing the distance E' between the first guide boundary point Z1 and the third guide boundary point Z3 in the direction perpendicular to the door side wall 32. P1 The distance E' between the third guide boundary point Z3 and the second guide boundary point Z2 P2 The ratio E` P1 :E` P2 , defines the lateral dimension relationship of the guide portion 50 in the direction perpendicular to the door side wall 32, so as to define the movement trend of the first axis 41 relative to the guide portion 50 when the door body 30 is opened. When the first axis 41 and the second axis 42 are set, E' P1 :E` P2 The extension tendency of the guide portion 50 is limited, thereby affecting the extension tendency of the guide portion 60, so as to ensure that the guide portion 50 and the guide portion 60 are arranged compactly, which is conducive to thinning the thickness of the door body 30. In addition, when the door body 30 is opened to the maximum angle, the geometric center of the door body 30 falls between the central axis of the first axis 41 and the central axis of the second axis 42, which increases the stability of the door body 30 when it is opened to the maximum angle.

[0293] E` above P1 :E` P2Being limited within the above range, on the one hand, the first side edge W of the door body 30, which can effectively block the access opening in the closed state, does not interfere with the storage cabinet 100 when it is opened, so that the door body 30 can be opened smoothly. On the other hand, the door body 30 has a larger inward and forward displacement when it is opened, so as to reduce the restriction of the storage cabinet 100 on the maximum angle that the door body 30 can open in it, thereby increasing the maximum angle that the door body 30 can open in the storage cabinet 100 (such as 113°, or 115°, or 120°).

[0294] In some embodiments of the present application, E' P1 Greater than the first guide side spacing reference value. For example, the first guide side spacing reference value is 8.5 mm, or 9 mm.

[0295] In some embodiments of the present application, E' P1 Smaller than the second guide side spacing reference value. For example, the second guide side spacing reference value is 10 mm, 12 mm, or 15 mm.

[0296] If E` P1 If it is too large, the size of the guide portion 50 in the direction perpendicular to the door side wall 32 will be too large, and the area occupied by the guide portion 50 at the end of the door body 30 will increase, resulting in an increase in the area hollowed out at the end of the door body 30 for setting the guide portion 50, thereby reducing the strength of the end of the door body 30.

[0297] If E` P1 If the size of the first axis 41 is too small, the guide portion 50 guides the movement of the first axis 41, thereby affecting the movement of the second axis 42 guided by the guide portion 60, reducing the amount of inward movement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue opening.

[0298] In some embodiments of the present application, E' P2 Greater than the first guide side spacing endpoint value. For example, the first guide side spacing endpoint value is 6.8 mm, 7.5 mm, or 8 mm.

[0299] In some embodiments of the present application, E' P2 Smaller than the second guide side spacing endpoint value. For example, the second guide side spacing endpoint value is 9mm, 10mm, 12mm, or 15mm.

[0300] If E` P2 If it is too large, the size of the guide portion 50 in the direction perpendicular to the door side wall 32 will be too large, and the area occupied by the guide portion 50 at the end of the door body 30 will increase, resulting in an increase in the area hollowed out at the end of the door body 30 for setting the guide portion 50, thereby reducing the strength of the end of the door body 30.

[0301] If E`P2 If the size is too small, the guide portion 50 guides the movement of the first axis 41, which in turn affects the movement tendency of the guide portion 60 to guide the second axis 42, reducing the displacement of the door body 30 inward and forward in the later stage of opening, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0302] In some embodiments of the present application, the distance between the first guide boundary point Z1 and the door side wall 32 is recorded as the first guide side distance D' P1 The distance between the second guide boundary point Z2 and the door side wall 32 is recorded as the second guide side distance D' P2 The distance between the third guide boundary point Z3 and the door side wall 32 is recorded as the third guide side distance D' P3 .

[0303] In some embodiments of the present application, D P1 Greater than the first guide side distance reference value. For example, the first guide side distance reference value is 26 mm, 27 mm, or 28 mm.

[0304] In some embodiments of the present application, D P1 Smaller than the second guide side distance reference value. For example, the second guide side distance reference value is 30 mm, 32 mm, or 34 mm.

[0305] In some embodiments of the present application, D P2 Greater than the first guide side distance endpoint value. For example, the first guide side distance endpoint value is 12mm, or 13mm.

[0306] In some embodiments of the present application, D P2 Smaller than the second guide side distance endpoint value. For example, the second guide side distance endpoint value is 14mm, 15mm, or 15.5mm.

[0307] In some embodiments of the present application, D P3 Greater than the first guide side distance reference value. For example, the first guide side distance reference value is 19 mm, 20 mm, or 21 mm.

[0308] In some embodiments of the present application, D P3 Smaller than the second guide side distance reference value. For example, the second guide side distance reference value is 21.5 mm, 22 mm, or 22.2 mm.

[0309] Above, E` P1 For D` P1 With D` P3 The difference; that is, E` P1 =D` P1 -D` P3 .

[0310] E` P2 For D` P3 With D` P2 The difference; that is, E` P2 =D` P3 -D` P2 .

[0311] The above is for D` P1 ,D` P2 ,D` P3 The limitation defines the lateral dimension relationship among the first guide boundary point Z1, the second guide boundary point Z2, and the third guide boundary point Z3 on the guide part 50 in the direction perpendicular to the door side wall 32, and defines the position of the guide part 50 relative to the door body 30, so as to define the movement trend of the first axis 41 relative to the guide part 50 when the door body 30 is opened; on the other hand, the above limitations enable the guide part 50 to be more suitable for the structure and space limitations of the finished door body 30.

[0312] The straight line where the first guide boundary point Z1 and the third guide boundary point Z3 are located is recorded as straight line Z1Z3; the straight line where the third guide boundary point Z3 and the second guide boundary point Z2 are located is recorded as straight line Z3Z2.

[0313] The angle between the straight line Z1Z3 and the door side wall 32 is recorded as the first guide side angle Ω` P1 The angle between the straight line Z3Z2 and the door side wall 32 is recorded as the second guide side angle Ω` P2 .

[0314] Ω` P1 :Ω` P2 Ω` P1 With Ω` P2 ratio.

[0315] In some embodiments of the present application, Ω` P1 >Ω` P2 .

[0316] In some embodiments of the present application, Ω` P1 :Ω` P2 Greater than the first guide side angle ratio. For example, the first guide side angle ratio is 1.2, 1.4, 1.5, or 1.6.

[0317] In some embodiments of the present application, Ω` P1 :Ω` P2 is smaller than the second guide side angle ratio. For example, the second guide side angle ratio is 1.7 or 1.8.

[0318] The first guide side angle Ω` P1 Angle Ω` with the second guide side P2The limitations of the relative relationship jointly determine the movement efficiency when the door is opened, making the track change movement more efficient and stable.

[0319] If Ω` P1 :Ω` P2 If the size of the door body 30 is too small, the guide portion 50 guides the movement of the first axis 41, which in turn affects the movement tendency of the guide portion 60 to guide the second axis 42, thereby reducing the inward displacement of the door body 30 in the later stage of opening, resulting in a reduction in the inward displacement of the door body 30 during the entire opening process, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0320] If Ω` P1 :Ω` P2 If the size of the first axis 41 is too large, the guide portion 50 guides the movement of the first axis 41, thereby affecting the movement of the second axis 42 guided by the guide portion 60, reducing the amount of inward movement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue opening.

[0321] In some embodiments of the present application, Ω` P1 is greater than the first guide side angle reference value. For example, the first guide side angle reference value is 32°, 33°, or 34°.

[0322] In some embodiments of the present application, Ω` P1 is smaller than the second guide side angle reference value. For example, the second guide side angle reference value is 37°, 39°, or 41°.

[0323] If the angle between the straight line Z1Z3 and the door side wall 32 is the first guide side angle Ω` P1 If it is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0324] If the angle between the straight line Z1Z3 and the door side wall 32 is the first guide side angle Ω` P1 If the angle between the first axis 41 and the guide portion 50 is too small, the projection of the line segment Z3Z2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point Z3 to the second guide boundary point Z2 of the guide portion 50, thereby reducing the displacement of the first axis 41 relative to the guide portion 50, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0325] In some embodiments of the present application, Ω` P2Greater than the first guide side angle endpoint value. For example, the first guide side angle endpoint value is 16°, 18°, 19°, or 20°.

[0326] In some embodiments of the present application, Ω` P2 Less than the second guide side angle endpoint value. For example, the second guide side angle endpoint value is 21°, or 22°.

[0327] If the angle between the straight line Z3Z2 and the door side wall 32 is the second guide side angle Ω` P2 If it is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0328] On the other hand, the second guide side angle Ω` P2 If the size of the door body 30 is too large, the inward displacement of the door body 30 in the later stage of opening is reduced, resulting in a reduction in the inward displacement of the door body 30 in the entire process of opening. The restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100 cannot be reduced, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0329] If the angle between the straight line Z3Z2 and the door side wall 32 is the second guide side angle Ω` P2 If the angle between the first axis 41 and the guide portion 50 is too small, the projection of the line segment Z3Z2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point Z3 to the second guide boundary point Z2 of the guide portion 50, thereby reducing the displacement of the first axis 41 relative to the guide portion 50, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0330] The angle between the straight line Z1Z3 and the door front wall 31 is recorded as the first guide front angle Ω P1 The angle between the straight line Z3Z2 and the door front wall 31 is recorded as the second guide front angle Ω P2 .

[0333] In some embodiments of the present application, Ω P1 :Ω P2 is greater than the first leading front angle ratio. For example, the first leading front angle ratio is 0.4, 0.5, 0.6, 0.7, or 0.8.

[0334] In some embodiments of the present application, Ω P1 :Ω P2 is smaller than the second leading front angle ratio. For example, the second leading front angle ratio is 0.9, or 0.94.

[0335] If Ω P1 :Ω P2 If the angle of the door body 30 is too large, the guide portion 50 guides the movement of the first axis 41, which further affects the movement tendency of the guide portion 60 to guide the second axis 42, thereby reducing the inward displacement of the door body 30 in the later stage of opening, resulting in a reduction in the inward displacement of the door body 30 during the entire opening process, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0336] If Ω P1 :Ω P2 If the size of the first axis 41 is too small, the guide portion 50 guides the movement of the first axis 41, thereby affecting the movement of the second axis 42 guided by the guide portion 60, reducing the amount of inward movement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue opening.

[0339] If the angle between the straight line Z1Z3 and the door front wall 31 is the first guide front angle Ω P1 If it is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0340] If the angle between the straight line Z1Z3 and the door front wall 31 is the first guide front angle Ω P1 If the angle between the first axis 41 and the guide portion 50 is too small, the projection of the line segment Z3Z2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point Z3 to the second guide boundary point Z2 of the guide portion 50, thereby reducing the displacement of the first axis 41 relative to the guide portion 50, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0342] In some embodiments of the present application, Ω P2 is smaller than the second leading front angle endpoint value. For example, the second leading front angle endpoint value is 70°, 72°, or 74°.

[0343] If the angle between the straight line Z3Z2 and the door front wall 31 is the second guide front angle Ω P2 If it is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0344] If the angle between the straight line Z3Z2 and the door front wall 31 is the second guide front angle Ω P2 If the angle between the first axis 41 and the guide portion 50 is too small, the projection of the line segment Z3Z2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point Z3 to the second guide boundary point Z2 of the guide portion 50, thereby reducing the displacement of the first axis 41 relative to the guide portion 50, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0345] The angle ∠Z1Z3Z2 between the straight line Z1Z3 and the straight line Z3Z2 is recorded as the guide angle Ω P .

[0346] In some embodiments of the present application, Ω P is greater than the first guide angle reference value. For example, the first guide angle reference value is 50°, 52°, or 54°.

[0347] In some embodiments of the present application, Ω P is smaller than the second guide angle reference value. For example, the second guide angle reference value is 56°, 58°, or 60°.

[0348] If the guide angle Ω P If the guide angle Ω is too large, the guide portion 50 will be flattened, which will affect the extension trend of the guide portion 50, reduce the displacement of the door body 30 inward during the opening process, and cannot reduce the restriction of the cabinet 100 on the maximum opening angle of the door body 30, which ultimately leads to a relatively small maximum opening angle of the door body 30 in the cabinet 100, which cannot meet the large angle requirement. In addition, the guide angle Ω PIf the size of the guide portion 50 in the direction perpendicular to the door front wall 31 is too large, the thickness of the door body 30 will increase, resulting in an increase in the obstruction of the door body 30 to the access opening. 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.

[0349] If the guide angle Ω P If the angle is too small, the first side edge W (door corner) will extend beyond the original position during the opening of the refrigerator, which may easily cause the first side edge W to interfere with the storage cabinet 100, and the door body 30 cannot be opened further. In order to allow the door body 30 to be opened to a larger angle in the storage cabinet 100, a larger gap needs to be reserved between the closed door body 30 and the storage cabinet 100 to avoid the first side edge W (door corner) from interfering with the storage cabinet 100. However, the larger gap reserved above causes the door body 30 to be unable to effectively cover the cabinet 10, affecting the overall appearance of the refrigerator.

[0350] In addition, the guide angle Ω P When the setting is too small, in order to ensure that the guide part 50 and the guide part 60 are not cross-connected, if the track width of the guide part 50 matched with the first shaft 41 and the guide part 60 matched with the second shaft 42 is reduced, the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly, which reduces the strength of the first shaft 41 and the second shaft 42, and easily causes the hinge assembly to be damaged and fail. If the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure its strength, the minimum distance (minimum wall thickness) between the guide part 50 and the guide part 60 will be reduced, resulting in a reduction in the strength of the guide part 50 and the guide part 60.

[0351] The length of line segment Z1Z3 is denoted as |Z1Z3|.

[0352] In some embodiments of the present application, |Z1Z3| is greater than a first guide distance reference value. For example, the first guide distance reference value is 15.8 mm, 15.9 mm, or 16 mm.

[0353] In some embodiments of the present application, |Z1Z3| is less than a second guide distance reference value. For example, the second guide distance reference value is 18 mm, 20 mm, or 22 mm.

[0354] The above definition of |Z1Z3| is combined with the first leading angle Ω P1 Or the first guide side angle Ω` P1 The limitation effectively limits the inward and forward movement of the door body 30 in the previous stage to avoid the first side edge W on the door body 30 from colliding with the storage cabinet 100.

[0355] The above |Z1Z3| combined with the first leading front angle Ω P1 Or the first guide side angle Ω` P1The lateral dimensions of the first guide boundary point Z1 and the third guide boundary point Z3 on the guide portion 50 in a direction perpendicular to the door side wall 32 and the longitudinal dimension relationship in a direction perpendicular to the door front wall 31 are jointly defined to limit the movement trend of the first axis 41 relative to the guide portion 50 when the door body 30 is opened, so that the door body 30 has a sufficient inward displacement in the early stage of opening to avoid interference between the first side edge W on the door body 30 and the storage cabinet 100; on the other hand, the above restrictions enable the guide portion 50 to be more suitable for the structure and space limitations of the finished door body 30.

[0356] In some embodiments of the present application, the length of line segment Z3Z2 is denoted as |Z3Z2|.

[0357] In some embodiments of the present application, |Z3Z2| is greater than the first guide distance endpoint value. For example, the first guide distance endpoint value is 14 mm, 18 mm, 20 mm, or 22 mm.

[0358] In some embodiments of the present application, |Z3Z2| is less than the second guide distance endpoint value. For example, the second guide distance endpoint value is 24 mm, 26 mm, or 28 mm.

[0359] The above definition of |Z3Z2| is combined with the second leading front angle Ω P2 Or the second guide side angle Ω` P2 The limitation effectively limits the door body 30 to enable the first side edge W to rotate quickly in the latter stage, so as to reduce the limitation of the storage cabinet 100 on the opening angle of the door body 30.

[0360] The above definition of |Z3Z2| is combined with the second leading front angle Ω P2 Or the second guide side angle Ω` P2 The lateral dimensions of the second guide boundary point Z2 and the third guide boundary point Z3 on the guide portion 50 in a direction perpendicular to the door side wall 32 and the longitudinal dimension relationship in a direction perpendicular to the door front wall 31 are jointly defined to limit the movement tendency of the first axis 41 relative to the guide portion 50 when the door body 30 is opened, so that the door body 30 has sufficient inward and forward displacement in the later stage of opening, so as to reduce the limitation of the space defined by the storage cabinet 100 on the maximum opening angle of the door body 30, thereby increasing the maximum opening angle of the door body 30; on the other hand, the above limitations enable the guide portion 5 to be more suitable for the structure and space limitations of the finished door body 30.

[0361] The distance between the first guide boundary point Z1 and the door front wall 31 is recorded as the first guide front distance D P1 The distance between the second guide boundary point Z2 and the door front wall 31 is recorded as the second guide front distance D P2 The distance between the third guide boundary point Z3 and the door front wall 31 is recorded as the third guide front distance D P3 .

[0362] In some embodiments of the present application, D P1 Greater than the first guide front distance reference value. For example, the first guide front distance reference value is 9 mm, 13 mm, 16 mm, or 20 mm.

[0363] In some embodiments of the present application, D P1 is smaller than the second guide front distance reference value. For example, the second guide front distance reference value is 21.3 mm, 22 mm, or 24 mm.

[0364] Above D P1 It is limited within the above range to ensure that the movement trajectory of the first shaft 41 does not encroach on the position occupied by the movement trajectory of the second shaft 42, so that the door body 30 has an area for fixing with screws or the like between the guide portion 50 and the guide portion 60.

[0365] In some embodiments of the present application, D P2 Greater than the first leading distance endpoint value. For example, the first leading distance endpoint value is 12mm, or 13mm.

[0366] In some embodiments of the present application, D P2 Smaller than the second leading distance endpoint value. For example, the second leading distance endpoint value is 14 mm, 16 mm, 18 mm, 20 mm, or 22 mm.

[0367] Above D P2 It is limited within the above range to ensure that the main part of the movement of the first axis 41 is as close to the front wall of the door as possible, so as to increase the supporting effect of the hinge plate 40 on the door body 30 and prevent the door body 30 from moving downward and deforming under its own gravity.

[0368] In some embodiments of the present application, D P3 Greater than the first guide front distance reference value. For example, the first guide front distance reference value is 30 mm, 33 mm, or 34 mm.

[0369] In some embodiments of the present application, D P3 Smaller than the second guide front distance reference value. For example, the second guide front distance reference value is 35mm, 36mm, or 38mm.

[0370] Above D P3 It is limited within the above range, which ensures that the door body 30 moves smoothly enough in the direction away from the storage cabinet 100, while making the first axis 41 as close to the front wall of the door as possible to increase the supporting effect of the hinge plate 40 on the door body 30, and prevent the door body 30 from moving downward and deforming under its own gravity.

[0371] |D P1 -D P2 | is the distance D between the first guide boundary point Z1 and the door front wall 31P1 The distance D between the second guide boundary point Z2 and the door front wall 31 P2 The absolute value of the difference. That is, |D P1 -D P2 | is the distance between the first guide boundary point Z1 and the second guide boundary point Z2 in the direction perpendicular to the door front wall 31.

[0372] In some embodiments of the present application, |D P1 -D P2 |Greater than the first pre-guiding spacing reference value. For example, the first pre-guiding spacing reference value is 6 mm, 7 mm, or 8 mm.

[0373] In some embodiments of the present application, |D P1 -D P2 |Smaller than the second pre-guiding spacing reference value. For example, the second pre-guiding spacing reference value is 10 mm, 12 mm, or 14 mm.

[0374] If |D P1 -D P2 | If the thickness of the wall between the guide part 50 and the guide part 60 is too large, the thickness of the wall between the guide part 50 and the guide part 60 will be too thin, which will reduce 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 track of the guide part 50 and the guide part 60 in the direction perpendicular to the door front wall 31 increases, resulting in an increase in the thickness of the door body 30, which affects the use on ultra-thin refrigerators.

[0375] When the guide portion 50 and the guide portion 60 are formed on a separate mounting block, the mounting block is fixedly connected to the door body 30 by screws or the like (not limited to screw fixing, any conventional fixing method that can fix two components together is acceptable). In order to ensure that the maximum angle that the door body 30 can open in the storage cabinet 100 is large enough, the thickness of the door body 30 should be reduced to meet user needs.

[0376] If |D P1 -D P2 |If it is too small, there will be insufficient space for fixing screws etc. (not limited to the screw fixing method, any conventional fixing method that can fix the two parts together) 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, the area of ​​the mounting block needs to be increased. In order to ensure the fixing strength of the mounting block, it is particularly necessary to increase the size of the mounting block in a direction perpendicular to the front wall 31 of the door, so as to increase the position for fixing screws etc. (not limited to the screw fixing method, any conventional fixing method that can fix the two parts together). The increase in the size of the mounting block in a 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 in ultra-thin refrigerators.

[0377] In some embodiments of the present application, the first guide boundary point Z1 is located on the side of the second guide boundary point Z2 away from the door front wall 31. P1 >D P2 .

[0378] In some embodiments of the present application, the first guide boundary point Z1 is located on the side of the second guide boundary point Z2 close to the door front wall 31. P1 <D P2 .

[0379] D P3 -D P2 is the distance D between the third guide boundary point Z3 and the door front wall 31 P3 The distance D between the second guide boundary point Z2 and the door front wall 31 P2 The difference. That is, D P3 -D P2 It is the distance between the third guide boundary point Z3 and the second guide boundary point Z2 in a direction perpendicular to the door front wall 31 .

[0380] In some embodiments of the present application, D P3 -D P2 Greater than the first leading-front spacing endpoint value. For example, the first leading-front spacing endpoint value is 18 mm, 19 mm, or 20 mm.

[0381] In some embodiments of the present application, D P3 -D P2 Smaller than the second leading-front spacing endpoint value. For example, the second leading-front spacing endpoint value is 22 mm, 24 mm, or 26 mm.

[0382] If D P3 -D P2 If the size of the door 30 is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0383] If D P3 -D P2 If the angle between the first axis 41 and the guide portion 50 is too small, the projection of the line segment Z3Z2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point Z3 to the second guide boundary point Z2 of the guide portion 50, thereby reducing the displacement of the first axis 41 relative to the guide portion 50, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0384] In some embodiments of the present application, in a direction perpendicular to the door front wall 31, the distance between the first guide boundary point Z1 and the third guide boundary point Z3 is recorded as the first guide front spacing E.P1 The distance between the third guide boundary point Z3 and the second guide boundary point Z2 is recorded as the second guide front spacing E P2 .

[0385] E P1 :E P2 For E P1 With E P2 ratio.

[0386] In some embodiments of the present application, E P1 :E P2 is greater than the first pre-leading spacing ratio. For example, the first pre-leading spacing ratio is 0.2, 0.4, or 0.6.

[0387] In some embodiments of the present application, E P1 :E P2 is smaller than the second pre-leading spacing ratio. For example, the second pre-leading spacing ratio is 0.7, 0.8, 0.9, or 1.

[0388] If E P1 :E P2 If the width of the door 30 is too large, the door body 30 will move inward too much in the early stage of opening, resulting in a significant increase in the amount of 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, it is necessary to reduce the lateral width of the drawer, resulting in a decrease in the utilization rate of the lateral space of the storage room by the drawer.

[0389] If E P1 :E P2 If the opening angle is too small, the inward displacement of the door body 30 in the later stage of opening is too small, and the restriction of the space defined by the storage cabinet 100 on the maximum opening angle of the door body 30 cannot be effectively reduced, thereby reducing the maximum opening angle of the door body 30.

[0390] In some embodiments of the present application, E P1 Greater than the first pre-guiding spacing reference value. For example, the first pre-guiding spacing reference value is 10 mm, 12 mm, or 13 mm.

[0391] In some embodiments of the present application, E P1 Smaller than the second pre-guiding spacing reference value. For example, the second pre-guiding spacing reference value is 14 mm, 16 mm, or 18 mm.

[0392] If the first leading distance E P1If the thickness of the door body 30 is too large, in order to ensure the maximum angle that the door body 30 can open in the storage cabinet 100, the distance from the third guide boundary point Z3 to the second guide boundary point Z2 of the guide part 50 needs to be large enough, so that the end point of the guide part 50 close to the door side wall 32 is set in the direction close to the door front wall 31, resulting in an increase in the size of the guide part 50 and the guide part 60 in the direction perpendicular to the door front wall 31, resulting in an increase in the thickness of the door body 30. If the thickness of the door body 30 is too large, the door body 30 will block the access port more; 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 use the horizontal space of the storage room.

[0393] At the same time, the end point position of the guide part 60 close to the door side wall 32 is affected, so that the end point of the guide part 60 close to the door side wall 32 is further arranged in the direction close to the door side wall 32; finally, the size of the guide part 50 and the guide part 60 as a whole in the direction perpendicular to the door side wall 32 is increased, resulting in an increase in the space hollowed out of the door body 30 in the direction perpendicular to the door side wall 32 due to the installation of the guide part 50 and the guide part 60, thereby reducing the strength of the end of the door body 30 having the guide part 50 and the guide part 60. On the other hand, the manufacturing cost is increased.

[0394] If the first leading distance E P1 If the angle of the door body 30 is too small, the distance moved inward and forward during the opening process of the door body 30 is small, and the door body 30 cannot be effectively and obviously caused to break away from the restriction of the maximum opening angle of the door body 30 by the storage cabinet 100, which ultimately causes the refrigerator to be unable to be opened to a larger angle in the storage cabinet 100 (such as the maximum opening angle is 90°, or 100°, and cannot be opened to a larger 113°, 115°, 120°), affecting the user experience.

[0395] In some embodiments of the present application, above, E P1 D P1 With D P3 The difference between P1 =D P1 -D P3 .

[0396] E above P1 =D P1 -D P3 Being limited within the above range, it is possible to ensure that the door body 30 moves smoothly in the early stage of opening.

[0397] In some embodiments of the present application, above, E P2 D P3 With D P2 The difference of E P2 =D P3 -D P2 That is, E P2The scope applies to D P3 -D P2 The scope of this application.

[0398] In some embodiments of the present application, E P2 =D P3 -D P2 Greater than the first leading-front spacing endpoint value. For example, the first leading-front spacing endpoint value is 18 mm, 19 mm, or 20 mm.

[0399] In some embodiments of the present application, E P2 =D P3 -D P2 Smaller than the second leading-front spacing endpoint value. For example, the second leading-front spacing endpoint value is 22 mm, 24 mm, or 26 mm.

[0400] If the second guide front spacing E P2 If the size of the door 30 is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0401] If the second guide front spacing E P2 If the angle between the first axis 41 and the guide portion 50 is too small, the projection of the line segment Z3Z2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point Z3 to the second guide boundary point Z2 of the guide portion 50, thereby reducing the displacement of the first axis 41 relative to the guide portion 50, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0402] In some embodiments of the present application, in the direction perpendicular to the door side wall 32, the distance between the first guide boundary point H1 and the third guide boundary point H3 is recorded as the first guide side spacing E' Q1 The distance between the third guide boundary point H3 and the second guide boundary point H2 is recorded as the second guide side spacing E' Q2 .

[0403] E` Q1 :E` Q2 For E` Q1 With E` Q2 ratio.

[0404] In some embodiments of the present application, E' Q1 :E` Q2 Greater than the first guide side spacing ratio. For example, the first guide side spacing ratio is 0.5, 1, or 2.

[0405] In some embodiments of the present application, E' Q1 :E` Q2is smaller than the second guide side spacing ratio. For example, the second guide side spacing ratio is 3, 4, or 5.

[0406] If E` Q1 :E` Q2 If the angle of the door 30 is too large, the distance the door body 30 moves inward and forward during opening is small, and the restriction of the storage cabinet 100 on the maximum opening angle of the door body 30 cannot be effectively reduced, which ultimately results in the refrigerator being unable to be opened to a larger angle in the storage cabinet 100 (such as the maximum opening angle is 90°, or 100°, and cannot be opened to a larger angle of 113°, 115°, 120°).

[0407] If E` Q1 :E` Q2 If the angle is too small, the first side edge W (door corner) will extend beyond the original position during the opening of the refrigerator, which may easily cause the first side edge W to interfere with the storage cabinet 100, and the door body 30 cannot be opened further. In order to allow the door body 30 to be opened to a larger angle in the storage cabinet 100, a larger gap needs to be reserved between the closed door body 30 and the storage cabinet 100 to avoid the first side edge W (door corner) from interfering with the storage cabinet 100. However, the larger gap reserved above causes the door body 30 to be unable to effectively cover the cabinet 10, affecting the overall appearance of the refrigerator.

[0408] The second trajectory line K of the present invention is obtained by optimizing the distance E' between the first guide boundary point H1 and the third guide boundary point H3 in the direction perpendicular to the door side wall 32. Q1 The distance E' between the third guide boundary point H3 and the second guide boundary point H2 Q2 The ratio E` Q1 :E` Q2 , which defines the lateral dimension relationship of the guide portion 60 in the direction perpendicular to the door side wall 32, so as to limit the movement of the second shaft 42 relative to the guide portion 60 when the door body 30 is opened. When the first shaft 41 and the second shaft 42 are set, E' Q1 :E` Q2 The extension tendency of the guide portion 60 is limited, thereby affecting the extension tendency of the guide portion 50, so as to ensure that the guide portion 50 and the guide portion 60 are arranged compactly, which is conducive to making the door body 30 thinner. In addition, when the door body 30 is opened to the maximum angle, the geometric center of the door body 30 falls between the central axis of the first axis 41 and the central axis of the second axis 42, which increases the stability of the door body 30 when it is opened to the maximum angle.

[0409] E` above Q1 :E` Q2Being limited within the above range, on the one hand, the first side edge W of the door body 30, which can effectively block the access opening in the closed state, does not interfere with the storage cabinet 100 when it is opened, so that the door body 30 can be opened smoothly. On the other hand, the door body 30 has a larger inward and forward displacement when it is opened, so as to reduce the restriction of the storage cabinet 100 on the maximum angle that the door body 30 can open in it, thereby increasing the maximum angle that the door body 30 can open in the storage cabinet 100 (such as 113°, or 115°, or 120°).

[0410] In some embodiments of the present application, E' Q1 Greater than the first guide side spacing reference value. For example, the first guide side spacing reference value is 24mm, 26mm, or 27mm.

[0411] In some embodiments of the present application, E' Q1 Smaller than the second guide side spacing reference value. For example, the second guide side spacing reference value is 29mm, 30mm, or 32mm.

[0412] If E` Q1 If it is too large, the dimension of the guide portion 60 in the direction perpendicular to the door side wall 32 will be too large, and the area of ​​the end of the door body 30 occupied by the guide portion 60 will increase, resulting in an increase in the area of ​​the end of the door body 30 hollowed out for setting the guide portion 60, thereby reducing the strength of the end of the door body 30.

[0413] If E` Q1 If the size of the second axis 42 is too small, the guide portion 60 will guide the movement of the second axis 42, thereby affecting the movement of the first axis 41 guided by the guide portion 50, reducing the amount of inward movement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and may easily cause the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue opening.

[0414] In some embodiments of the present application, E' Q2 Greater than the first guide side spacing endpoint value. For example, the first guide side spacing endpoint value is 6.5mm, 7mm, or 9mm.

[0415] In some embodiments of the present application, E' Q2 Smaller than the second guide side spacing endpoint value. For example, the second guide side spacing endpoint value is 11mm, 13mm, or 15mm.

[0416] If E` Q2 If it is too large, the dimension of the guide portion 60 in the direction perpendicular to the door side wall 32 will be too large, and the area of ​​the end of the door body 30 occupied by the guide portion 60 will increase, resulting in an increase in the area of ​​the end of the door body 30 hollowed out for setting the guide portion 60, thereby reducing the strength of the end of the door body 30.

[0417] If E`Q2 If the size is too small, the guide portion 60 guides the movement of the second axis 42, which in turn affects the movement tendency of the guide portion 50 to guide the first axis 41, reducing the displacement of the door body 30 inward and forward in the later stage of opening, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0418] In some embodiments of the present invention, the distance between the first guide boundary point H1 and the door side wall 32 is recorded as the first guide side distance D' Q1 The distance between the second guide boundary point H2 and the door side wall 32 is recorded as the second guide side distance D' Q2 The distance between the third guide boundary point H3 and the door side wall 32 is recorded as the third guide side distance D' Q3 .

[0419] In some embodiments of the present application, D Q1 Greater than the first guide side spacing reference value. For example, the first guide side spacing reference value is 40mm, 44mm, or 48mm.

[0420] In some embodiments of the present application, D Q1 Smaller than the second guide side spacing reference value. For example, the second guide side spacing reference value is 50mm, 52mm, or 54mm.

[0421] In some embodiments of the present application, D Q2 Greater than the first guide side spacing endpoint value. For example, the first guide side spacing endpoint value is 5mm, 7mm, or 9mm.

[0422] In some embodiments of the present application, D Q2 Smaller than the second guide side spacing endpoint value. For example, the second guide side spacing endpoint value is 12mm, 14mm, or 16mm.

[0423] In some embodiments of the present application, D Q2 Greater than the first guide side spacing reference value. For example, the first guide side spacing reference value is 19 mm, 20 mm, or 21 mm.

[0424] In some embodiments of the present application, D Q2 Smaller than the second guide side spacing reference value. For example, the second guide side spacing reference value is 22mm, 24mm, or 26mm.

[0425] Above, E` Q1 For D` Q1 With D` Q3 The difference; that is, E` Q1 =D` Q1 -D` Q3.

[0426] E` Q2 For D` Q3 With D` Q2 The difference; that is, E` Q2 =D` Q3 -D` Q2 .

[0427] The above is for D` Q1 ,D` Q2 ,D` Q3 The limitation defines the lateral dimension relationship among the first guide boundary point H1, the second guide boundary point H2, and the third guide boundary point H3 on the guide portion 60 in the direction perpendicular to the door side wall 32, and defines the position of the guide portion 60 relative to the door body 30, so as to define the movement trend of the second axis 41 relative to the guide portion 60 when the door body 30 is opened; on the other hand, the above limitations enable the guide portion 60 to be more suitable for the structure and space limitations of the finished door body 30.

[0428] The straight line where the first guide boundary point H1 and the third guide boundary point H3 are located is recorded as straight line H1H3; the straight line where the third guide boundary point H3 and the second guide boundary point H2 are located is recorded as straight line H3H2.

[0429] In some embodiments of the present application, the angle between the straight line H1H3 and the door side wall 32 is recorded as the first guide side angle Ω` Q1 The angle between the straight line H3H2 and the door side wall 32 is recorded as the second guide side angle Ω` Q2 .

[0430] In some embodiments of the present application, Ω` Q1 >Ω` Q2 .

[0431] Ω` Q1 :Ω` Q2 Ω` Q1 With Ω` Q2 ratio.

[0432] In some embodiments of the present application, Ω` Q1 :Ω` Q2 Greater than the first guide side angle ratio. For example, the first guide side angle ratio is 0.5, 0.7, or 0.9.

[0433] In some embodiments of the present application, Ω` Q1 :Ω` Q2 Less than the second guide side angle ratio. For example, the second guide side angle ratio is 1.1, 1.15, or 1.17.

[0434] If Ω` Q1 :Ω` Q2If the size of the second axis 42 is too small, the guide portion 60 will guide the movement of the second axis 42, which will further affect the movement tendency of the guide portion 50 to guide the first axis 41, thereby reducing the inward displacement of the door body 30 in the later stage of opening, resulting in a reduction in the inward displacement of the door body 30 in the entire process of opening. It is unable to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0435] If Ω` Q1 :Ω` Q2 If the size of the second axis 42 is too large, the guide portion 60 will guide the movement of the second axis 42, thereby affecting the tendency of the guide portion 50 to guide the movement of the first axis 41, reducing the amount of inward movement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and may easily cause the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue opening.

[0436] In some embodiments of the present application, Ω` Q1 Greater than the first guide side angle reference value. For example, the first guide side angle reference value is 36°, 38°, or 40°.

[0437] In some embodiments of the present application, Ω` Q1 is smaller than the second guide side angle reference value. For example, the second guide side angle reference value is 41°, or 41.1°.

[0438] If the angle between the straight line H1H3 and the door side wall 32 is the first guide side angle Ω` Q1 If the angle between the second axis 42 and the guide portion 60 is too large, the projection of the line segment H3H2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point H3 to the second guide boundary point H2 of the guide portion 60, thereby reducing the displacement of the second axis 42 relative to the guide portion 60, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0439] If the angle between the straight line H1H3 and the door side wall 32 is the first guide side angle Ω` Q1 If it is too small, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0440] In some embodiments of the present application, Ω` Q2 Greater than the first guide side angle endpoint value. For example, the first guide side angle endpoint value is 36°, 37°, 38°, or 39°.

[0441] In some embodiments of the present application, Ω` Q2Smaller than the second guide side angle endpoint value. For example, the second guide side angle endpoint value is 40°, 44°, or 48°.

[0442] If the angle between the straight line H3H2 and the door side wall 32 is the second guide side angle Ω` Q2 If the angle between the second axis 42 and the guide portion 60 is too large, the projection of the line segment H3H2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point H3 to the second guide boundary point H2 of the guide portion 60, thereby reducing the displacement of the second axis 42 relative to the guide portion 60, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0443] If the angle between the straight line H3H2 and the door side wall 32 is the second guide side angle Ω` Q2 If it is too small, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0444] In some embodiments of the present application, the angle between the straight line H1H3 and the door front wall 31 is recorded as the first guide front angle Ω Q1 The angle between the straight line H3H2 and the door front wall 31 is recorded as the second guide front angle Ω Q2 .

[0445] In some embodiments of the present application, Ω Q1 <Ω Q2 .

[0446] Ω Q1 :Ω Q2 Ω Q1 With Ω Q2 ratio.

[0447] In some embodiments of the present application, Ω Q1 :Ω Q2 is greater than the first guide rake angle ratio. For example, the first guide rake angle ratio is 0.5, 0.6, or 0.7.

[0448] In some embodiments of the present application, Ω Q1 :Ω Q2 is smaller than the second guide rake angle ratio. For example, the second guide rake angle ratio is 0.8, 0.85, or 0.88.

[0449] If Ω Q1 :Ω Q2If the size of the second axis 42 is too large, the guide portion 60 guides the movement of the second axis 42, which in turn affects the movement tendency of the guide portion 50 to guide the first axis 41, reducing the inward displacement of the door body 30 in the later stage of opening, resulting in a reduction in the inward displacement of the door body 30 in the entire process of opening. It is unable to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0450] If Ω Q1 :Ω Q2 If the size of the second axis 42 is too small, the guide portion 60 will guide the movement of the second axis 42, thereby affecting the tendency of the guide portion 50 to guide the movement of the first axis 41, reducing the amount of inward movement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and may easily cause the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue opening.

[0451] In some embodiments of the present application, Ω Q1 is greater than the first guide rake angle reference value. For example, the first guide rake angle reference value is 48.9° or 49°.

[0452] In some embodiments of the present application, Ω Q1 is smaller than the second guide rake angle reference value. For example, the second guide rake angle reference value is 50°, 52°, or 54°.

[0453] If the angle between the straight line H1H3 and the front wall 31 of the door is the first guide front angle Ω Q1 If it is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0454] If the angle between the straight line H1H3 and the front wall 31 of the door is the first guide front angle Ω Q1 If the angle of the guide portion 60 is too small, the projection of the line segment H3H2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point H3 to the second guide boundary point H2 of the guide portion 60, thereby reducing the displacement of the second axis 42 relative to the guide portion 60, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0455] In some embodiments of the present application, Ω Q2 Greater than the first guide front angle endpoint value. For example, the first guide front angle endpoint value is 54°, 60°, 62°, 64°, 66°, or 68°.

[0456] In some embodiments of the present application, Ω Q2Less than the second guide front angle endpoint value. For example, the second guide front angle endpoint value is 70°, 72°, 74°, or 76°.

[0457] If the angle between the straight line H3H2 and the front wall 31 of the door is the second guide front angle Ω Q2 If it is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0458] If the angle between the straight line H3H2 and the front wall 31 of the door is the second guide front angle Ω Q2 If the angle of the guide portion 60 is too small, the projection of the line segment H3H2 in the direction perpendicular to the door front wall 31 will be reduced, thereby reducing the distance from the third guide boundary point H3 to the second guide boundary point H2 of the guide portion 60, thereby reducing the displacement of the second axis 42 relative to the guide portion 60, limiting the maximum angle that the door body 30 can open in the storage cabinet 100.

[0459] The angle ∠H1H3H2 between the straight line H1H3 and the straight line H3H2 is recorded as the guide angle Ω Q .

[0460] In some embodiments of the present application, Ω Q is greater than the first guide angle reference value. For example, the first guide angle reference value is 77°, 79°, or 80°.

[0461] In some embodiments of the present application, Ω Q Less than or equal to the second guide angle reference value. For example, the second guide angle reference value is 82°, 85°, 88°, or 90°.

[0462] If the conduction angle Ω Q If the size of the door body 30 is too large, the guide portion 60 will be flattened, which will simultaneously affect the extension trend of the guide portion 50, reduce the inward displacement of the door body 30 during opening, and fail to reduce the restriction of the storage cabinet 100 on the maximum opening angle of the door body 30. Ultimately, the maximum opening angle of the door body 30 in the storage cabinet 100 is relatively small and cannot meet the large angle requirement.

[0463] In addition, the conduction angle Ω Q If the size of the guide portion 60 in the direction perpendicular to the door front wall 31 is too large, the size will increase, resulting in an increase in the thickness of the door body 30, and an increase in 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, 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.

[0464] Furthermore, the conduction angle Ω QIf the size of the guide portion 60 is too large, the length of the guide portion 60 increases. In order to maintain the continuity of the movement, the first shaft 41 needs to be withdrawn relative to the guide portion 50 (from withdrawing from the movement direction close to the door side wall 32 to moving away from the door side wall 32), resulting in increased movement of the first shaft 41 and additional wear on the first shaft 41 and the guide portion 40.

[0465] If the conduction angle Ω Q If the angle is too small, the first side edge W (door corner) will extend beyond the original position during the opening of the refrigerator, which may easily cause the first side edge W to interfere with the storage cabinet 100, and the door body 30 cannot be opened further. In order to allow the door body 30 to be opened to a larger angle in the storage cabinet 100, a larger gap needs to be reserved between the closed door body 30 and the storage cabinet 100 to avoid the first side edge W (door corner) from interfering with the storage cabinet 100. However, the larger gap reserved above causes the door body 30 to be unable to effectively cover the cabinet 10, affecting the overall appearance of the refrigerator.

[0466] In addition, the conduction angle Ω Q When the setting is too small, in order to ensure that the guide part 50 and the guide part 60 are not cross-connected, if the track width of the guide part 50 matched with the first shaft 41 and the guide part 60 matched with the second shaft 42 is reduced, the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly, which reduces the strength of the first shaft 41 and the second shaft 42, and easily causes the hinge assembly to be damaged and fail. If the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure its strength, the minimum distance (minimum wall thickness) between the guide part 50 and the guide part 60 will be reduced, resulting in a reduction in the strength of the guide part 50 and the guide part 60.

[0467] The length of line segment H1H3 is denoted as |H1H3|.

[0468] In some embodiments of the present application, |H1H3| is greater than a first guide distance reference value. For example, the first guide distance reference value is 36 mm, 38 mm, 40 mm, or 42 mm.

[0469] In some embodiments of the present application, |H1H3| is less than the second guide distance reference value. For example, the second guide distance reference value is 43 mm, 45 mm, 49 mm, or 50 mm.

[0470] The above |H1H3| combined with the first guide front angle Ω Q1 Or the first guide side angle Ω` Q1The lateral dimensions of the first guide boundary point H1 and the third guide boundary point H3 on the guide portion 60 in a direction perpendicular to the door side wall 32 and the longitudinal dimension relationship in a direction perpendicular to the door front wall 31 are jointly defined to limit the movement tendency of the second axis 42 relative to the guide portion 60 when the door body 30 is opened, so that the door body 30 has a sufficient inward displacement in the early stage of opening to avoid interference between the first side edge W on the door body 30 and the storage cabinet 100; on the other hand, the above restrictions enable the guide portion 60 to be more suitable for the structure and space limitations of the finished door body 30.

[0471] The length of line segment H3H2 is denoted as |H3H2|.

[0472] In some embodiments of the present application, |H3H2| is greater than a first guide distance reference value. For example, the first guide distance reference value is 11 mm, 13 mm, 15 mm, or 16 mm.

[0473] In some embodiments of the present application, |H3H2| is less than the second guide distance reference value. For example, the second guide distance reference value is 17 mm, 19 mm, 21 mm, or 23 mm.

[0474] The above definition of |H3H2| is combined with the second guide front angle Ω Q2 Or the second guide side angle Ω` Q2 The lateral dimensions of the second guide boundary point H2 and the third guide boundary point H3 on the guide portion 60 in a direction perpendicular to the door side wall 32 and the longitudinal dimension relationship in a direction perpendicular to the door front wall 31 are jointly defined to limit the movement tendency of the second axis 42 relative to the guide portion 60 when the door body 30 is opened, so that the door body 30 has sufficient inward and forward displacement in the later stage of opening, so as to reduce the limitation of the space defined by the storage cabinet 100 on the maximum opening angle of the door body 30, thereby increasing the maximum opening angle of the door body 30; on the other hand, the above limitations enable the guide portion 5 to be more suitable for the structure and space limitations of the finished door body 30.

[0475] In some embodiments of the present application, the first guide boundary point H1, the third guide boundary point H3, and the second guide boundary point H2 are successively close to the door side wall 32. That is, the distances between the first guide boundary point H1, the third guide boundary point H3, and the second guide boundary point H2 and the door side wall 32 are successively reduced. That is, in the direction parallel to the door front wall 31 or perpendicular to the door side wall 32, the third guide boundary point H3 is located between the first guide boundary point H1 and the second guide boundary point H2.

[0476] The distance between the first guide boundary point H1 and the door front wall 31 is recorded as the first guide front distance D Q1 The distance between the second guide boundary point H2 and the door front wall 31 is recorded as the second guide front distance D Q2The distance between the third guide boundary point H3 and the door front wall 31 is recorded as the third guide front distance D Q3 .

[0477] In some embodiments of the present application, D Q1 Greater than the first guide front distance reference value. For example, the first guide front distance reference value is 12.7 mm, 13 mm, or 13.2 mm.

[0478] In some embodiments of the present application, D Q1 Smaller than the second guide front distance reference value. For example, the second guide front distance reference value is 17 mm, 19 mm, 21 mm, or 23 mm.

[0479] Above D Q1 It is limited within the above range to ensure that the movement trajectory of the second shaft 42 does not encroach on the position occupied by the movement trajectory of the first shaft 41, so that the door body 30 has an area for fixing with screws or the like between the guide portion 50 and the guide portion 60.

[0480] In some embodiments of the present application, D Q2 Greater than the first guide front distance endpoint value. For example, the first guide front distance endpoint value is 29mm, 31mm, or 32mm.

[0481] In some embodiments of the present application, D Q2 Smaller than the second guide front distance endpoint value. For example, the second guide front distance endpoint value is 34mm, 36mm, 38mm, 40mm, or 41mm.

[0482] Above D Q2 It is limited within the above range, while ensuring that the setting of the guide part 50 and the guide part 60 enables the door body 30 to be opened to the maximum angle, and at the same time ensuring that when the second axis moves to the end of the guide part 60 close to the door side wall 32, the wall thickness between the end of the guide part 60 close to the door side wall 32 and the guide part 50 cannot be too small, thereby ensuring the strength of the guide part 50 and the guide part 60.

[0483] In some embodiments of the present application, D Q3 Greater than the first guide front distance reference value. For example, the first guide front distance reference value is 36mm, 39mm, 42mm, or 45mm.

[0484] In some embodiments of the present application, D Q3 Smaller than the second guide front distance reference value. For example, the second guide front distance reference value is 46mm, 48mm, 49mm, or 50mm.

[0485] Above D Q3It is limited within the above range to ensure the dimensions of the guide portion 50 and the guide portion 60 in a direction perpendicular to the door front wall 31, so as to facilitate a thinner thickness of the door body 30; on the other hand, the motion trajectory guide portion 60 of the second axis 42 is made as close as possible to the motion trajectory guide portion 50 of the first axis 41, thereby increasing the compactness of the arrangement of the guide portion 50 and the guide portion 60.

[0486] |D Q1 -D Q2 | is the distance D between the first guide boundary point H1 and the door front wall 31 Q1 The distance D between the second guide boundary point H2 and the door front wall 31 Q2 The absolute value of the difference. Q1 -D Q2 | is the distance between the first guide boundary point H1 and the second guide boundary point H2 in a direction perpendicular to the door front wall 31.

[0487] In some embodiments of the present application, |D Q1 -D Q2 | is greater than the first guide front spacing reference value. For example, the first guide front spacing reference value is 16 mm, 18 mm, or 19 mm.

[0488] In some embodiments of the present application, |D Q1 -D Q2 |Smaller than the second guide front spacing reference value. For example, the second guide front spacing reference value is 20 mm, 24 mm, 27 mm, or 28 mm.

[0489] If |D Q1 -D Q2 | is too large. In order to ensure the maximum angle that the door body 30 can open in the storage cabinet 100, the distance from the third guide boundary point H3 to the second guide boundary point H2 of the guide portion 60 needs to be large enough so that the end point of the guide portion 60 close to the door side wall 32 is set in a direction close to the door front wall 31, resulting in an increase in the size of the guide portion 50 and the guide portion 60 as a whole in a direction perpendicular to the door front wall 31, resulting in an increase in the thickness of the door body 30. If the thickness of the door body 30 is too large, the door body 30 will block the access port more; 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.

[0490] At the same time, the end point of the guide portion 60 close to the door side wall 32 is further arranged in the direction close to the door side wall 32; finally, the size of the guide portion 50 and the guide portion 60 as a whole in the direction perpendicular to the door side wall 32 increases, resulting in an increase in the space of the door body 30 hollowed out in the direction perpendicular to the door side wall 32 due to the installation of the guide portion 50 and the guide portion 60, thereby reducing the strength of the end of the door body 30 having the guide portion 50 and the guide portion 60. On the other hand, the manufacturing cost is increased.

[0491] If |D Q1 -D Q2 | is too small, and the distance that the door body 30 moves inward and forward during opening is small, and it is impossible to effectively and obviously cause the door body 30 to escape from the restriction of the maximum opening angle of the door body 30 by the storage cabinet 100, which ultimately causes the refrigerator to be unable to be opened to a larger angle in the storage cabinet 100 (for example, the maximum opening angle is 90°, or 100°, and cannot be opened to a larger 113°, 115°, 120°), affecting the user experience.

[0492] In some embodiments of the present application, the first guide boundary point H1 is located on the side of the second guide boundary point H2 close to the door front wall 31. Q1 <D Q2 .

[0493] The distance D between the third guide boundary point H3 and the door front wall 31 Q3 The distance D between the second guide boundary point H2 and the door front wall 31 Q2 The difference is recorded as D Q3 -D Q2 That is, D Q3 -D Q2 It is the distance between the third guide boundary point H3 and the second guide boundary point H2 in a direction perpendicular to the door front wall 31 .

[0494] In some embodiments of the present application, D Q3 -D Q2 Greater than the first guide front spacing endpoint value. For example, the first guide front spacing endpoint value is 9mm, 10mm, or 11mm.

[0495] In some embodiments of the present application, D Q3 -D Q2 Smaller than the second guide front spacing endpoint value. For example, the second guide front spacing endpoint value is 13mm, 15mm, 17mm, or 20mm.

[0496] If D Q3 -D Q2 If the size of the door 30 is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0497] If D Q3 -D Q2If the angle is too small, the inward displacement of the door body 30 in the later stage of opening is reduced, resulting in a reduction in the inward displacement of the door body 30 in the entire process of opening. The restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100 cannot be reduced, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0498] In some embodiments of the present application, the second guide boundary point H2 is located on a side of the first guide boundary point H1 close to the door rear wall 33. The third guide boundary point H3 is located on a side of the second guide boundary point H2 close to the door rear wall 33.

[0499] In some embodiments of the present application, the distance between the first guide boundary point H1 and the third guide boundary point H3 in the direction perpendicular to the door front wall 31 is recorded as the first guide front spacing E. Q1 The distance between the third guide boundary point H3 and the second guide boundary point H2 is recorded as the second guide front spacing E Q2 .

[0500] E Q1 :E Q2 For E Q1 With E Q2 ratio.

[0501] In some embodiments of the present application, E Q1 :E Q2 Greater than the first pre-guide spacing ratio. For example, the first pre-guide spacing ratio is 1.5, 1.7, 1.9, 2, or 2.5.

[0502] In some embodiments of the present application, E Q1 :E Q2 Less than the second pre-guide spacing ratio. For example, the second pre-guide spacing ratio is 2.6, 3, 3.5, 4, or 4.2.

[0503] If E Q1 :E Q2 If the width of the door 30 is too large, the door body 30 will move inward too much in the early stage of opening, resulting in a significant increase in the amount of 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, it is necessary to reduce the lateral width of the drawer, resulting in a decrease in the utilization rate of the lateral space of the storage room by the drawer.

[0504] If E Q1 :E Q2 If the opening angle is too small, the inward displacement of the door body 30 in the later stage of opening is too small, and the restriction of the space defined by the storage cabinet 100 on the maximum opening angle of the door body 30 cannot be effectively reduced, thereby reducing the maximum opening angle of the door body 30.

[0505] In some embodiments of the present application, E Q1Greater than the first guide front spacing reference value. For example, the first guide front spacing reference value is 27mm, 29mm, or 31mm.

[0506] In some embodiments of the present application, E Q1 Smaller than the second guide front spacing reference value. For example, the second guide front spacing reference value is 33mm, 35mm, 37mm, or 37.7mm.

[0507] Since the guiding portion 50 and the guiding portion 60 are formed on a separate mounting block, the mounting block is fixedly connected to the door body 30 by screws or the like (not limited to screw fixing methods, any conventional fixing method that can fix the two components is acceptable); in order to ensure that the maximum angle that the door body 30 can be opened in the storage cabinet 100 is large enough, the thickness of the door body 30 should be reduced to meet user needs.

[0508] If E Q1 If the size of the mounting block is too large, there will be insufficient space for screws (not limited to screw fixation, any conventional fixation 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 a direction perpendicular to the door front wall 31, so as to increase the position for screws (not limited to screw fixation, any conventional fixation method that can fix two components together). The increase in the size of the mounting block in a direction perpendicular to the door front wall 31 will increase the thickness of the door body 30 that matches it, affecting its use in ultra-thin refrigerators.

[0509] If E Q1 The smaller the E, the thinner the wall thickness between the guide part 50 and the guide part 60 will be, which will reduce the strength of the guide part 50 and the guide part 60. Q1 In order to ensure that the door body 30 can be opened at a large enough angle in the storage cabinet 100, the relative positions of the first axis 41 and the second axis 42 need to be adjusted. The first axis 41 needs to be set in the direction close to the door front wall 31, and at the same time, the fixing position (such as the screw position) for fixing the mounting block on the side close to the door front wall 31 is also set in the direction close to the door front wall 31. The above will directly lead to an increase in the size of the mounting block in a direction perpendicular to the door front wall 31, which will lead to an increase in the thickness of the door body 30 adapted thereto.

[0510] In some embodiments of the present application, above, E Q1 D Q1 With D Q3 The difference between Q1 =D Q1 -D Q3 .

[0511] In some embodiments of the present application, above, EQ2 D Q3 With D Q2 The difference between Q2 =D Q3 -D Q2 That is, E Q2 The scope applies to D Q3 -D Q2 The scope of this application.

[0512] In some embodiments of the present application, E Q2 Greater than the first guide front spacing endpoint value. For example, the first guide front spacing endpoint value is 9mm, 10mm, or 11mm.

[0513] In some embodiments of the present application, E Q2 Smaller than the second guide front spacing endpoint value. For example, the second guide front spacing endpoint value is 13mm, 15mm, 17mm, or 20mm.

[0514] If the second guide front distance E Q2 If the size of the door 30 is too large, the thickness of the door body 30 will be too large, resulting in increased 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, 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.

[0515] If the second guide front distance E Q2 In order to ensure that the door body 30 can be opened at a sufficiently large angle in the storage cabinet 100, the relative positions of the first axis 41 and the second axis 42 need to be adjusted. The first axis 41 needs to be set in the direction close to the door front wall 31, and at the same time, the fixing position (such as the screw position) for fixing the mounting block on the side close to the door front wall 31 is also set in the direction close to the door front wall 31. The above will directly lead to an increase in the size of the mounting block in a direction perpendicular to the door front wall 31, which will lead to an increase in the thickness of the door body 30 adapted thereto.

[0516] For the guide portion 50 and the guide portion 60 , the straight line where the first guide boundary point Z1 and the second guide boundary point Z2 are located is recorded as straight line Z1Z2, and the straight line where the first guide boundary point H1 and the second guide boundary point H2 are located is recorded as straight line H1H2.

[0517] The angle between the straight line Z1Z2 and the straight line H1H2 is recorded as the first relative angle δ1.

[0518] In some embodiments of the present application, δ1 is greater than a first relative angle reference value. For example, the first relative angle reference value is 46°, 48°, 50°, or 52°.

[0519] In some embodiments of the present application, δ1 is less than a second relative angle reference value. For example, the second relative angle reference value is 54°, 56°, 58°, or 60°.

[0520] The thicker the door body 30 is, the easier it is to design the trajectory (the guide portion 50 and the guide portion 60) to control the door body to complete the set movement. However, if the door body 30 is thicker, the obstruction of the access port will increase when the door is opened at 90° or to the maximum angle.

[0521] If the first relative angle δ1 is too large, the dimension of the overall trajectory of the guide portion 50 and the guide portion 60 in the direction perpendicular to the door front wall 31 is increased, resulting in an increase in the thickness of the door body 30 and an increase in 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, 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.

[0522] If the first relative angle δ1 is set too small, in order to ensure that the guide portion 50 and the guide portion 60 are not cross-connected, if the track width of the guide portion 50 matched with the first shaft 41 and the guide portion 60 matched with the second shaft 42 is reduced, the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly, which reduces the strength of the first shaft 41 and the second shaft 42, and easily causes the hinge assembly to be damaged and fail. If the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure its 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.

[0523] The first relative angle δ1 is limited within the above range, so that the guide portion 50 and the guide portion 60 are both extended along the width direction of the door body 30, reducing the occupation of the thickness space of the door body by the guide portion 50 and the guide portion 60, which is conducive to making the door body 30 thinner. At the same time, the overall strength of the first shaft 41, the second shaft 42, the guide portion 50, and the guide portion 60 can also be ensured.

[0524] In some embodiments of the present application, the angle between the straight line Z1Z2 and the door front wall 31 is recorded as the third guide front angle Ω P3 , the angle between the straight line H1H2 and the door front wall 31 is recorded as the third guide front angle Ω Q3 .

[0525] Ω P3 :Ω Q3 Ω P3 With Ω Q3 ratio.

[0526] In some embodiments of the present application, Ω P3 :Ω Q3 is greater than the first rake angle ratio. For example, the first rake angle ratio is 0.5, 0.7, or 0.9.

[0527] In some embodiments of the present application, Ω P3 :Ω Q3is smaller than the second rake angle ratio. For example, the second rake angle ratio is 1, 1.1, or 1.2.

[0528] If Ω P3 :Ω Q3 If the guide portion 50 and the guide portion 60 are set too large, in order to ensure that they are not cross-connected, if the track width of the guide portion 50 matched with the first shaft 41 and the guide portion 60 matched with the second shaft 42 is reduced, the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly, which reduces the strength of the first shaft 41 and the second shaft 42, and easily causes the hinge assembly to be damaged and fail. If the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure its 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.

[0529] If Ω P3 :Ω Q3 If the size of the guide portion 50 and the guide portion 60 is too small, the dimension of the overall trajectory of the guide portion 50 and the guide portion 60 in the direction perpendicular to the door front wall 31 is increased, resulting in an increase in the thickness of the door body 30 and an increase in 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, 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.

[0530] In some embodiments of the present application, Ω P3 is greater than the first guide front angle reference value. For example, the first guide front angle reference value is 21°, 23°, or 25°.

[0531] In some embodiments of the present application, Ω P3 is smaller than the second guide front angle reference value. For example, the second guide front angle reference value is 26°, 28°, or 30°.

[0532] If the third leading angle Ω P3 If the size is too large, the wall thickness between the guide part 50 and the guide part 60 will be 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 track 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, which affects the use on the ultra-thin refrigerator.

[0533] If the third leading angle Ω P3If the size is too small, there will be insufficient space for screws (not limited to screw fixation, any conventional fixation method that can fix two components together) between the two tracks of the guide portion 50 and the guide portion 60 on the mounting block. 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 a direction perpendicular to the door front wall 31, so as to increase the position for screws (not limited to screw fixation, any conventional fixation method that can fix two components together). The increase in the size of the mounting block in a direction perpendicular to the door front wall 31 will increase the thickness of the door body 30 that matches it, affecting its use in ultra-thin refrigerators.

[0534] In some embodiments of the present application, Ω Q3 is greater than the first guide rake angle reference value. For example, the first guide rake angle reference value is 18°, 20°, 24°, or 26°.

[0535] In some embodiments of the present application, Ω Q3 is smaller than the second guide rake angle reference value. For example, the second guide rake angle reference value is 28°, 30°, 32°, 34°, or 36°.

[0536] If the third guide rake angle Ω Q3 If the guide portion 60 is too large, in order to ensure the maximum angle that the door body 30 can open in the storage cabinet 100, the distance from the third guide boundary point H3 to the second guide boundary point H2 of the guide portion 60 needs to be large enough so that the end point of the guide portion 60 close to the door side wall 32 is set in a direction close to the door front wall 31, resulting in an increase in the size of the guide portion 50 and the guide portion 60 in a direction perpendicular to the door front wall 31, resulting in an increase in the thickness of the door body 30. If the thickness of the door body 30 is too large, the door body 30 will block the access port more; 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 use the horizontal space of the storage room.

[0537] At the same time, the end point of the guide portion 60 close to the door side wall 32 is further arranged in the direction close to the door side wall 32; finally, the size of the guide portion 50 and the guide portion 60 as a whole in the direction perpendicular to the door side wall 32 increases, resulting in an increase in the space of the door body 30 hollowed out in the direction perpendicular to the door side wall 32 due to the installation of the guide portion 50 and the guide portion 60, thereby reducing the strength of the end of the door body 30 having the guide portion 50 and the guide portion 60. On the other hand, the manufacturing cost is increased.

[0538] If the third guide rake angle Ω Q3If the angle of the door body 30 is too small, the distance moved inward and forward during the opening process of the door body 30 is small, and the door body 30 cannot be effectively and obviously caused to break away from the restriction of the maximum opening angle of the door body 30 by the storage cabinet 100, which ultimately causes the refrigerator to be unable to be opened to a larger angle in the storage cabinet 100 (such as the maximum opening angle is 90°, or 100°, and cannot be opened to a larger 113°, 115°, 120°), affecting the user experience.

[0539] In some embodiments of the present application, the angle between the straight line Z1Z2 and the door side wall 32 is recorded as the third guide side angle Ω` P3 The angle between the straight line H1H2 and the door side wall 32 is recorded as the third guide side angle Ω` Q3 .

[0540] Ω` P3 :Ω` Q3 Ω` P3 With Ω` Q3 ratio.

[0541] In some embodiments of the present application, Ω` P3 :Ω` Q3 is greater than the first side angle ratio. For example, the first side angle ratio is 0.6, 0.8, 0.9, or 1.

[0542] In some embodiments of the present application, Ω` P3 :Ω` Q3 is smaller than the second side angle ratio. For example, the second side angle ratio is 1.1, 1.2, 1.4, 1.5, or 1.6.

[0543] If Ω` P3 :Ω` Q3 If the size of the guide portion 50 and the guide portion 60 is too large, the dimension of the overall trajectory of the guide portion 50 and the guide portion 60 in the direction perpendicular to the door front wall 31 is increased, resulting in an increase in the thickness of the door body 30 and an increase in 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, 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.

[0544] If Ω` P3 :Ω` Q3 If the guide portion 50 and the guide portion 60 are set too small, in order to ensure that they are not cross-connected, if the track width of the guide portion 50 matched with the first shaft 41 and the guide portion 60 matched with the second shaft 42 is reduced, the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly, which reduces the strength of the first shaft 41 and the second shaft 42, and easily causes the hinge assembly to be damaged and fail. If the diameter of the first shaft 41 and the second shaft 42 is ensured 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.

[0545] In some embodiments of the present application, Ω` P3 Greater than the first guide side angle reference value. For example, the first guide side angle reference value is 58°, 60°, 62°, or 64°.

[0546] In some embodiments of the present application, Ω` P3 is smaller than the second guide side angle reference value. For example, the second guide side angle reference value is 65°, 67°, or 69°.

[0547] If the third guide side angle Ω` P3 If the size of the mounting block is too large, there will be insufficient space for screws (not limited to screw fixation, any conventional fixation 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 a direction perpendicular to the door front wall 31, so as to increase the position for screws (not limited to screw fixation, any conventional fixation method that can fix two components together). The increase in the size of the mounting block in a direction perpendicular to the door front wall 31 will increase the thickness of the door body 30 that matches it, affecting its use in ultra-thin refrigerators.

[0548] If the third guide side angle Ω` P3 If the size is too small, the wall thickness between the guide part 50 and the guide part 60 will be 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 track 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, which affects the use on the ultra-thin refrigerator.

[0549] In some embodiments of the present application, Ω` Q3 Greater than the first guide side angle reference value. For example, the first guide side angle reference value is 56°, 58°, 60°, or 62°.

[0550] In some embodiments of the present application, Ω` Q3 is smaller than the second guide side angle reference value. For example, the second guide side angle reference value is 64°, 68°, 72°, or 76°.

[0551] If the third guide side angle Ω` Q3If the angle of the door 30 is too large, the distance moved inward and forward during the opening process of the door body 30 is small, and the door body 30 cannot be effectively and obviously caused to break away from the restriction of the maximum opening angle of the door body 30 by the storage cabinet 100, which ultimately causes the refrigerator to be unable to be opened to a larger angle in the storage cabinet 100 (such as the maximum opening angle is 90°, or 100°, and cannot be opened to a larger 113°, 115°, 120°), affecting the user experience.

[0552] If the third guide side angle Ω` Q3 If the guide portion 60 is too small, in order to ensure the maximum angle that the door body 30 can open in the storage cabinet 100, the distance from the third guide boundary point H3 to the second guide boundary point H2 of the guide portion 60 needs to be large enough so that the end point of the guide portion 60 close to the door side wall 32 is set in a direction close to the door front wall 31, resulting in an increase in the size of the guide portion 50 and the guide portion 60 in a direction perpendicular to the door front wall 31, resulting in an increase in the thickness of the door body 30. If the thickness of the door body 30 is too large, the door body 30 will block the access port more; 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 use the horizontal space of the storage room.

[0553] At the same time, the end point of the guide portion 60 close to the door side wall 32 is further arranged in the direction close to the door side wall 32; finally, the size of the guide portion 50 and the guide portion 60 as a whole in the direction perpendicular to the door side wall 32 increases, resulting in an increase in the space of the door body 30 hollowed out in the direction perpendicular to the door side wall 32 due to the installation of the guide portion 50 and the guide portion 60, thereby reducing the strength of the end of the door body 30 having the guide portion 50 and the guide portion 60. On the other hand, the manufacturing cost is increased.

[0554] The length of line segment Z1Z2 is denoted as |Z1Z2|.

[0555] In some embodiments of the present application, |Z1Z2| is greater than a first guide distance reference value. For example, the first guide distance reference value is 16 mm, 17 mm, or 18 mm.

[0556] In some embodiments of the present application, |Z1Z2| is less than a second guide distance reference value. For example, the second guide distance reference value is 20 mm, 22 mm, or 25 mm.

[0557] The above definition of |Z1Z2| is combined with the third leading front angle Ω P3 Or the third guide side angle Ω` P3The horizontal dimension relationship between the first guide boundary point Z1 and the second guide boundary point Z2 on the guide portion 50 in the direction perpendicular to the door side wall 32 and the longitudinal dimension relationship in the direction perpendicular to the door front wall 31 is jointly defined to limit the movement trend of the first axis 41 relative to the guide portion 50 when the door body 30 is opened, so that the door body 30 has a sufficient displacement amount to move inward and forward throughout the opening process, so as to reduce the limitation of the space defined by the storage cabinet 100 on the maximum opening angle of the door body 30. On the other hand, the above limitations enable the guide portion 50 to be more suitable for the structure and space limitations of the finished door body 30.

[0558] The length of line segment H1H2 is denoted as |H1H2|.

[0559] In some embodiments of the present application, |H1H2| is greater than a first guide distance reference value. For example, the first guide distance reference value is 39 mm, 41 mm, 42 mm, or 43 mm.

[0560] In some embodiments of the present application, |H1H2| is smaller than the second guide distance reference value. For example, the second guide distance reference value is 45 mm, 47 mm, or 48 mm.

[0561] The above |H1H2| combined with the third guide front angle Ω` Q3 Or the third guide side angle Ω` Q3 The horizontal dimension relationship between the first guide boundary point H1 and the second guide boundary point H2 on the guide portion 60 in the direction perpendicular to the door side wall 32 and the longitudinal dimension relationship in the direction perpendicular to the door front wall 31 is jointly defined to limit the movement trend of the second axis 42 relative to the guide portion 60 when the door body 30 is opened, so that the door body 30 has a sufficient displacement amount moving inward and forward during the whole process of opening, so as to reduce the limitation of the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100. On the other hand, the above limitation enables the guide portion 50 to be more suitable for the structure and space limitation of the finished door body 30.

[0562] In some embodiments of the present application, the first guide boundary point H1 , the first guide boundary point Z1 , the second guide boundary point Z2 , and the second guide boundary point H2 are sequentially close to the door side wall 32 .

[0563] In some embodiments of the present application, the second guide boundary point Z2, the first guide boundary point H1, the first guide boundary point Z1, and the second guide boundary point H2 are close to the door rear wall 33 in sequence.

[0564] In some embodiments of the present application, Figure 4 The straight line passing through the third guiding boundary point Z3 and perpendicular to the straight line Z1Z2 is recorded as the first straight line χ1. The first straight line χ1 intersects the straight line Z1Z2 at the first perpendicular foot Z C That is, the triangle Z1Z2Z3 has the side Z1Z2 as the base and the height on the side as the line segment Z3ZC , and Z C For the dangling feet.

[0565] In some embodiments of the present application, the first vertical foot Z C On line segment Z1Z2.

[0566] If the first perpendicular Z C On the extension line of line segment Z1Z2, the guide portion 50 guides the movement of the first axis 41, thereby affecting the movement tendency of the guide portion 60 to guide the second axis 42, reducing the inward displacement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making the door body 30 unable to continue opening.

[0567] Among them, line segment Z3Z C The length of |Z3Z C |, the length of line segment Z1Z2 is |Z1Z2|, and the length of line segment Z1Z C The length of |Z1Z C |, line segment Z C The length of Z2 is denoted by |Z C Z2|.

[0568] In some embodiments of the present application, C |Greater than the first guide height reference value. For example, the first guide height reference value is 39 mm, 41 mm, or 43 mm.

[0569] In some embodiments of the present application, C | is less than the second guide height reference value. For example, the second guide height reference value is 45 mm, 47 mm, or 48 mm.

[0570] If | Z3Z C | is too small, the guide portion 50 is flattened, which will affect the extension trend of the guide portion 50, reduce the displacement of the door body 30 inward during the opening process, and cannot reduce the restriction of the storage cabinet 100 on the maximum opening angle of the door body 30, which ultimately leads to a relatively small maximum opening angle of the door body 30 in the storage cabinet 100, which cannot meet the large angle requirement. In addition, the guide angle Ω P If the size of the guide portion 50 in the direction perpendicular to the door front wall 31 is too large, the thickness of the door body 30 will increase, resulting in an increase in the obstruction of the door body 30 to the access opening. 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.

[0571] If | Z3Z C|If the first side edge W (door corner) is too large, the first side edge W (door corner) will extend beyond the original position during the opening of the refrigerator, which may easily cause the first side edge W to interfere with the storage cabinet 100, and the door body 30 cannot be opened further. In order to allow the door body 30 to be opened to a larger angle in the storage cabinet 100, a larger gap needs to be reserved between the closed door body 30 and the storage cabinet 100 to avoid the first side edge W (door corner) from interfering with the storage cabinet 100. However, the larger gap reserved above causes the door body 30 to be unable to effectively cover the cabinet 10, affecting the overall appearance of the refrigerator.

[0572] In addition, |Z3Z C |When the diameter is too large, in order to ensure that the guide part 50 and the guide part 60 are not cross-connected, if the track width of the guide part 50 matched with the first shaft 41 and the guide part 60 matched with the second shaft 42 is reduced, the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly, which reduces the strength of the first shaft 41 and the second shaft 42, and easily causes the hinge assembly to be damaged and fail. If the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure its strength, the minimum distance (minimum wall thickness) between the guide part 50 and the guide part 60 will be reduced, resulting in a reduction in the strength of the guide part 50 and the guide part 60.

[0573] Above|Z3Z C |It is limited to the above range, which determines the extension trend of the guide portion 50 and reserves space for the guide portion 60 to avoid interference between the guide portions 50 and 60.

[0574] In some embodiments of the present application, C The ratio of |Z1Z2| to |Z1Z2| is greater than the first pilot ratio. For example, the first pilot ratio is 0.4, 0.6, 0.8, or 0.82.

[0575] In some embodiments of the present application, C The ratio of |Z1Z2| to |Z1Z2| is less than the second guide ratio. For example, the second guide ratio is 0.9, or 1.

[0576] If | Z3Z C When the ratio of | to |Z1Z2| is too large, the dimension of the guide portion 50 in the direction perpendicular to the door front wall 31 increases, resulting in an increase in the thickness of the door body 30 and an increase in the obstruction of the door body 30 to the access opening. 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.

[0577] If | Z3Z CThe ratio of | to |Z1Z2| is too small, and the guide portion 50 is flattened, which will synchronously affect the extension trend of the guide portion 60, reduce the inward displacement of the door body 30 during the opening process, and cannot reduce the restriction of the storage cabinet 100 on the maximum opening angle of the door body 30, ultimately resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being relatively small, which cannot meet the large angle requirement.

[0578] In some embodiments of the present application, C |Greater than or equal to the first guide length reference value. For example, the first guide length reference value is 0 mm, 1 mm, 2 mm, or 2.5 mm.

[0579] In some embodiments of the present application, C | is smaller than the second guide length reference value. For example, the second guide length reference value is 3 mm, or 4 mm.

[0580] If |Z1Z C | is too large, the guide portion 50 guides the movement of the first axis 41, which further affects the movement trend of the guide portion 60 guiding the second axis 42, reducing the displacement of the door body 30 moving inwards in the later stage of opening, resulting in a reduction in the displacement of the door body 30 moving inwards during the entire process of opening, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0581] If |Z1Z C | is too small, the guide portion 50 guides the movement of the first axis 41, which in turn affects the movement trend of the guide portion 60 guiding the second axis 42, reducing the displacement of the door body 30 inwardly moving in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue to open.

[0582] In some embodiments of the present application, |Z C Z2| is greater than the first guide length endpoint value. For example, the first guide length endpoint value is 13 mm, 14 mm, 16 mm, or 15 mm.

[0583] In some embodiments of the present application, |Z C Z2| is less than the second guide length endpoint value. For example, the second guide length endpoint value is 17 mm, 19 mm, 22 mm, or 25 mm.

[0584] If |Z CZ2| is too large, the guide portion 50 guides the movement of the first axis 41, which in turn affects the movement tendency of the guide portion 60 to guide the second axis 42, reducing the inward displacement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue to open.

[0585] If |Z C Z2| is too small, the guide portion 50 guides the movement of the first axis 41, which further affects the movement tendency of the guide portion 60 to guide the second axis 42, reducing the inward displacement of the door body 30 in the later stage of opening, resulting in a reduction in the inward displacement of the door body 30 during the entire opening process, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0586] In some embodiments of the present application, C |with|Z C The ratio of Z2| is greater than or equal to the first guide length ratio. For example, the first guide length ratio is 0, 0.1, or 0.15.

[0587] In some embodiments of the present application, C |with|Z C The ratio of Z2| is less than the second guide length ratio. For example, the second guide length ratio is 0.2, 0.3, or 0.4.

[0588] If |Z1Z C |with|Z C Z2| is too large, the guide portion 50 guides the movement of the first axis 41, which further affects the movement tendency of the guide portion 60 to guide the second axis 42, reducing the inward displacement of the door body 30 in the later stage of opening, resulting in a reduction in the inward displacement of the door body 30 during the entire opening process, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0589] In some embodiments of the present application, Figure 4 The straight line passing through the third guide boundary point H3 and perpendicular to the straight line H1H2 is recorded as the second straight line χ2. The second straight line χ2 intersects the straight line H1H2 at the foot of the second perpendicular H C ; That is, the triangle H1H2H3 has side H1H2 as the base and the height on the side as the line segment H3H C , and H C For the dangling feet.

[0590] In some embodiments of the present application, the second vertical foot HC On line segment H1H2. Line segment H3H C The length of |H3H C |, the length of line segment H1H2 is |H1H2|, and the length of line segment H1H C The length is recorded as |H1H C |, line segment H C The length of H2 is denoted by |H C H2|.

[0591] In some embodiments of the present application, |H3H C |Greater than the first guide height reference value. For example, the first guide height reference value is 11 mm, 13 mm, or 15 mm.

[0592] In some embodiments of the present application, |H3H C |Small than the second guide height reference value. For example, the second guide height reference value is 17 mm, 19 mm, 22 mm, or 25 mm.

[0593] If |H3H C | is too small, and the guide portion 60 is flattened, which will synchronously affect the extension trend of the guide portion 50, reduce the inward displacement of the door body 30 during the opening process, and cannot reduce the restriction of the storage cabinet 100 on the maximum opening angle of the door body 30, ultimately resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being relatively small, which cannot meet the large angle requirement.

[0594] In addition, |H3H C |If it is too small, the dimension of the guide portion 60 in the direction perpendicular to the door front wall 31 increases, resulting in an increase in the thickness of the door body 30, and an increase in the blocking 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, 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.

[0595] Furthermore, |H3H C | is too small, the length of the guide portion 60 increases, and in order to maintain the continuity of movement, the first shaft 41 needs to be withdrawn relative to the guide portion 50 (from withdrawing from the movement direction close to the door side wall 32 to moving away from the door side wall 32), resulting in increased movement of the first shaft 41 and additional wear on the first shaft 41 and the guide portion 40.

[0596] If |H3H C|If the first side edge W (door corner) is too large, the first side edge W (door corner) will extend beyond the original position during the opening of the refrigerator, which may easily cause the first side edge W to interfere with the storage cabinet 100, and the door body 30 cannot be opened further. In order to allow the door body 30 to be opened to a larger angle in the storage cabinet 100, a larger gap needs to be reserved between the closed door body 30 and the storage cabinet 100 to avoid the first side edge W (door corner) from interfering with the storage cabinet 100. However, the larger gap reserved above causes the door body 30 to be unable to effectively cover the cabinet 10, affecting the overall appearance of the refrigerator.

[0597] In addition, |H3H C |When the diameter is too large, in order to ensure that the guide part 50 and the guide part 60 are not cross-connected, if the track width of the guide part 50 matched with the first shaft 41 and the guide part 60 matched with the second shaft 42 is reduced, the diameter of the first shaft 41 and the second shaft 42 needs to be reduced accordingly, which reduces the strength of the first shaft 41 and the second shaft 42, and easily causes the hinge assembly to be damaged and fail. If the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure its strength, the minimum distance (minimum wall thickness) between the guide part 50 and the guide part 60 will be reduced, resulting in a reduction in the strength of the guide part 50 and the guide part 60.

[0598] Above|H3H C |It is limited to the above range, which determines the extension trend of the guide portion 60 and reserves space for the guide portion 50 to avoid interference between the guide portion 50 and the guide portion 60.

[0599] In some embodiments of the present application, |H3H C The ratio of | to |H1H2| is greater than the first guide ratio. For example, the first guide ratio is 0.25, 0.3, or 0.35.

[0600] In some embodiments of the present application, |H3H C The ratio of | to |H1H2| is less than the second guide ratio. For example, the second guide ratio is 0.4, 0.5, or 0.6.

[0601] If |H3H C When the ratio of | to |H1H2| is too large, the dimension of the guide portion 60 in the direction perpendicular to the door front wall 31 increases, resulting in an increase in the thickness of the door body 30 and an increase in the obstruction of the door body 30 to the access opening. 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.

[0602] If |H3H CThe ratio of | to |H1H2| is too small, and the guide portion 60 is flattened, which will synchronously affect the extension trend of the guide portion 50, reduce the inward displacement of the door body 30 during the opening process, and cannot reduce the restriction of the storage cabinet 100 on the maximum opening angle of the door body 30, ultimately resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being relatively small, which cannot meet the large angle requirement.

[0603] In some embodiments of the present application, |H1H C |Greater than the first guide length reference value. For example, the first guide length reference value is 36 mm, 38 mm, or 39 mm.

[0604] In some embodiments of the present application, |H1H C |Smaller than the second guide length reference value. For example, the second guide length reference value is 40 mm, 43 mm, 46 mm, 48 mm, or 49 mm.

[0605] If |H1H C | is too large, the guide portion 60 guides the second axis 42, which in turn affects the movement trend of the guide portion 50 guiding the first axis 41, reducing the displacement of the door body 30 moving inwards in the later stage of opening, resulting in a reduction in the displacement of the door body 30 moving inwards during the entire opening process, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0606] If |H1H C | is too small, the guide portion 60 guides the second axis 42, which in turn affects the movement trend of the guide portion 50 guiding the first axis 41, reducing the displacement of the door body 30 inwardly moving in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue to open.

[0607] In some embodiments of the present application, |H C H2| is greater than the first guide length endpoint value. For example, the first guide length endpoint value is 1 mm, 2 mm, or 3 mm.

[0608] In some embodiments of the present application, |H C H2| is smaller than the second guide length endpoint value. For example, the second guide length endpoint value is 4 mm, 5 mm, 6 mm, or 8 mm.

[0609] If |H CH2| is too large, the guide portion 60 guides the second axis 42, which in turn affects the movement trend of the guide portion 50 guiding the first axis 41, reducing the inward displacement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue to open.

[0610] If |H C H2| is too small, the guide portion 60 guides the second axis 42, which further affects the movement trend of the guide portion 50 guiding the first axis 41, reducing the inward displacement of the door body 30 in the later stage of opening, resulting in a reduction in the inward displacement of the door body 30 during the entire opening process, and failing to reduce the restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0611] In some embodiments of the present application, |H1H C |with|H C The ratio of H2| is greater than the first guide length ratio. For example, the first guide length ratio is 9, 10, or 11.

[0612] In some embodiments of the present application, |H1H C |with|H C The ratio of H2| is less than the second guide length ratio. For example, the second guide length ratio is 12, 13, 14, or 15.

[0613] If |H1H C |with|H C When the ratio of H2| is too large, the guide portion 60 guides the second axis 42, which in turn affects the movement trend of the guide portion 50 guiding the first axis 41, thereby reducing the inward displacement of the door body 30 in the later stage of opening, resulting in a reduction in the inward displacement of the door body 30 during the entire opening process. The restriction on the maximum opening angle of the door body 30 by the space defined by the storage cabinet 100 cannot be reduced, resulting in the maximum opening angle of the door body 30 in the storage cabinet 100 being limited to a smaller angle, which is inconvenient for users to take and put items.

[0614] If |H1H C |with|H C If the ratio of H2| is too small, the guide portion 60 guides the second axis 42, which in turn affects the movement trend of the guide portion 50 guiding the first axis 41, reducing the inward displacement of the door body 30 in the early stage of opening, which is not conducive to the first side edge W on the door body 30 avoiding the storage cabinet 100, and easily causes the first side edge W to collide with the storage cabinet 100, making it impossible for the door body 30 to continue to open.

[0615] |D P1 -D Q1| is the distance D between the first guide boundary point Z1 and the door front wall 31 P1 The distance D between the first guide boundary point H1 and the door front wall 31 Q1 The absolute value of the difference. P1 -D Q1 | is the distance between the first guide boundary point Z1 and the first guide boundary point H1 and the door front wall 31 in a direction perpendicular to the door front wall 31.

[0616] In some embodiments of the present application, in the direction perpendicular to the door front wall 31, the distance between the first guide boundary point Z1 and the first guide boundary point H1 is denoted as |D P1 -D Q1 |.

[0617] In some embodiments of the present application, |D P1 -D Q1 |Greater than the first relative front distance reference value. For example, the first relative front distance reference value is 2 mm, 4 mm, 6 mm, or 7 mm.

[0618] In some embodiments of the present application, |D P1 -D Q1 |Smaller than the second relative front distance reference value. For example, the second relative front distance reference value is 8 mm, 8.2 mm, or 8.4 mm.

[0619] If the longitudinal dimension of the guide portion 50 away from one end of the door side wall 32 and the guide portion 60 away from one end of the door side wall 32 along the direction perpendicular to the door front wall 31 |D P1 -D Q1 | is too large, the guide portion 50 and the guide portion 60 are loosely arranged in the longitudinal direction, and the overall track formed by the guide portion 50 and the guide portion 60 increases in size in the direction perpendicular to the door front wall 31, resulting in an increase in the thickness of the door body 30, resulting in an increase in 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, 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.

[0620] If the longitudinal dimension of the guide portion 50 away from one end of the door side wall 32 and the guide portion 60 away from one end of the door side wall 32 along the direction perpendicular to the door front wall 31 |D P1 -D Q1| is too small, the guide part 50 and the guide part 60 are arranged too compactly. In order to avoid the guide part 60 of the guide part 50 not being cross-connected, as a way, the track width of the guide part 50 matched with the first shaft 41 and the guide part 60 matched 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 is easy to cause damage to the hinge assembly and failure. As another way, the diameter of the first shaft 41 and the second shaft 42 is ensured to ensure its strength, then the minimum distance (minimum wall thickness) between the guide part 50 and the guide part 60 will be reduced, resulting in a reduction in the strength of the guide part 50 and the guide part 60.

[0621] In some embodiments of the present application, the first guide boundary point Z1 is located on a side of the first guide boundary point H1 close to the door front wall 31. P1 <D Q1 .

[0622] In some embodiments of the present application, the first guide boundary point Z1 is located on a side of the first guide boundary point H1 away from the door front wall 31. P1 >D Q1 .

[0623] In some embodiments of the present application, in the direction perpendicular to the door side wall 32, the distance between the first guide boundary point Z1 and the first guide boundary point H1 is denoted as |D` P1 -D` Q1 |.

On the other hand, the manufacturing cost is increased.

[0628] If the guide portion 50 is away from one end of the door side wall 32 and the guide portion 60 is away from one end of the door side wall 32 along the lateral dimension perpendicular to the door side wall 32 | D` P1 -D` Q1 If the size of the mounting block is too small, there will be insufficient space for screws (not limited to screw fixation, any conventional fixation 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 a direction perpendicular to the door front wall 31, so as to increase the position for screws (not limited to screw fixation, any conventional fixation method that can fix two components together). If the size of the mounting block in a direction perpendicular to the door front wall 31 increases, the thickness of the door body 30 that matches it will increase, affecting its use in ultra-thin refrigerators.

[0629] |D P1 -D Q1 |、|D` P1 -D` Q1 |Together they define the relative positional relationship between the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 away from the door side wall 32, and effectively define the longitudinal dimension of the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 away from the door side wall 32 along the direction perpendicular to the door front wall 31 and the lateral dimension of the end of the guide portion 50 away from the door side wall 32.

[0630] In some embodiments of the present application, the first guide boundary point Z1 is located on a side of the first guide boundary point H1 close to the door side wall 32. P1 <D` Q1 .

[0631] In some embodiments of the present application, the distance between the first guide boundary point Z1 and the first guide boundary point H1 is recorded as |Z1H1|, that is, the length of the line segment Z1H1 is recorded as |Z1H1|.

[0632] In some embodiments of the present application, |Z1H1| is greater than a first relative distance reference value. For example, the first relative distance reference value is 16 mm, 18 mm, or 19 mm.

[0633] In some embodiments of the present application, |Z1H1| is less than a second relative distance reference value. For example, the second relative distance reference value is 21 mm, 23 mm, or 25 mm.

[0634] In some embodiments of the present application, the angle between the straight line Z1H1 where the first guide boundary point Z1 and the first guide boundary point H1 are located and the door front wall 31 is recorded as the first relative front angle ζ1.

[0635] In some embodiments of the present application, ζ1 is greater than a first relative rake angle reference value. For example, the first relative rake angle reference value is 18°, 20°, or 22°.

[0636] In some embodiments of the present application, ζ1 is less than a second relative rake angle reference value. For example, the second relative rake angle reference value is 24°, 24.2°, or 24.5°.

[0637] In some embodiments of the present application, the angle between the straight line Z1H1 and the door side wall 32 is recorded as the first relative side angle ζ`1.

[0638] In some embodiments of the present application, ζ`1 is greater than a first relative side angle reference value. For example, the first relative side angle reference value is 65.5°, 66°, or 66.5°.

[0639] In some embodiments of the present application, ζ`1 is less than the second relative side angle reference value. For example, the second relative side angle reference value is 67°, 68°, or 70°.

[0640] As mentioned above, any one of the first relative front angle ζ1 or the first relative side angle ζ`1 and the length |Z1H1| of the line segment Z1H1 jointly define the relative position relationship between the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 away from the door side wall 32, and effectively define the longitudinal dimension of the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 away from the door side wall 32 along the direction perpendicular to the door front wall 31 and the lateral dimension of the end of the guide portion 50 away from the door side wall 32.

[0641] If the longitudinal dimensions of the guide portion 50 away from one end of the door side wall 32 and the guide portion 60 away from one end of the door side wall 32 in the direction perpendicular to the door front wall 31 are too large, the guide portion 50 and the guide portion 60 are loosely arranged in the longitudinal direction, and the overall trajectory formed by the guide portion 50 and the guide portion 60 increases in dimension in the direction perpendicular to the door front wall 31, resulting in an increase in the thickness of the door body 30, 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.

[0642] If the longitudinal dimension of the guide portion 50 away from the door side wall 32 and the guide portion 60 away from the door side wall 32 is too small in the direction perpendicular to the door front wall 31, 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 matched with the first shaft 41 and the guide portion 60 matched 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. However, 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 is easy to 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, then 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.

[0643] If the lateral dimensions of the guide portion 50 and the guide portion 60 away from the door side wall 32 are too large in the direction perpendicular to the door side wall 32, the guide portion 50 and the guide portion 60 are arranged loosely in the lateral direction, resulting in an increase in the overall dimensions of the guide portion 50 and the guide portion 60 in the direction perpendicular to the door side wall 32, resulting in an increase in the space of the door body 30 hollowed out in the direction perpendicular to the door side wall 32 due to the provision of the guide portion 50 and the guide portion 60, thereby reducing the strength of the end of the door body 30 having the guide portion 50 and the guide portion 60. On the other hand, the manufacturing cost is increased.

[0644] If the lateral dimensions of the guide portion 50 away from one end of the door side wall 32 and the guide portion 60 away from one end of the door side wall 32 are too small in a direction perpendicular to the door side wall 32, there will be insufficient space 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 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 a 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 a direction perpendicular to the door front wall 31 will increase the thickness of the door body 30 that matches it, affecting its use on ultra-thin refrigerators.

[0645] The above first relative side angle ζ`1 is limited within the above range, which ensures that the end of the guide portion 50 away from the door side wall 32 is located on the side of the end of the guide portion 60 away from the door side wall 32, close to the door side wall 32 and away from the door front wall 31; on the one hand, it ensures that the guide portion 50 moving relative to the door body 30 by the first axis 41 does not overlap with the guide portion 60 moving relative to the door body 30 by the second axis 42, so as to ensure the integrity of the guide portion 50 and the guide portion 60; on the other hand, there is space between the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 away from the door side wall 32 for fixing with screws.

[0646] In some embodiments of the present application, in the direction perpendicular to the door front wall 31, the distance between the second guide boundary point Z2 and the first guide boundary point H1 is denoted as |D P2 -D Q1 |.

[0647] |D P2 -D Q1 | is the distance D between the second guide boundary point Z2 and the door front wall 31 P2 The distance D between the first guide boundary point H1 and the door front wall 31 Q1 The absolute value of the difference.

[0648] In some embodiments of the present application, |D P2 -D Q1 | Greater than or equal to the first relative front distance endpoint value. For example, the first relative front distance endpoint value is 0 mm, 0.1 mm, or 0.2 mm.

[0649] In some embodiments of the present application, |D P2 -D Q1 | is smaller than the second relative front distance endpoint value. For example, the second relative front distance endpoint value is 1 mm, 3 mm, or 5 mm.

[0650] If the longitudinal dimension of the guide portion 50 close to the door side wall 32 and the guide portion 60 away from the door side wall 32 along the direction perpendicular to the door front wall 31 is |D P2 -D Q1 | is too large, when the first guide boundary point H1 is set closer to the door front wall 31 than the second guide boundary point Z2 (D P2 >D Q1 ), the distance between the end of the guide portion 50 close to the door side wall 32 and the door front wall 31 increases, reducing the maximum angle that the door body 30 can open, affecting the user experience.

[0651] When the second guide boundary point Z2 is set closer to the door front wall 31 than the first guide boundary point H1 (D P2 >D Q1), the end of the guide portion 50 close to the door side wall 32 is closer to the door front wall 31, and the overall track formed by the guide portion 50 and the guide portion 60 increases in size in a direction perpendicular to the door front wall 31, resulting in an increase in the thickness of the door body 30, resulting in an increase in 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, 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.

[0652] In some embodiments of the present application, in a direction perpendicular to the door side wall 32, the distance between the second guide boundary point Z2 and the first guide boundary point H1 is |D` P2 -D` Q1 |.

[0653] |D` P2 -D` Q1 | is the distance D' between the second guide boundary point Z2 and the door side wall 32 P2 The distance D' between the first guide boundary point H1 and the door side wall 32 Q1 The absolute value of the difference.

[0654] In some embodiments of the present application, |D` P2 -D` Q1 | is greater than the first opposite side distance endpoint value. For example, the first opposite side distance endpoint value is 34mm, or 35mm.

[0655] In some embodiments of the present application, |D` P2 -D` Q1 |Smaller than the second opposite side distance endpoint value. For example, the second opposite side distance endpoint value is 36 mm, 38 mm, or 40 mm.

[0656] If the lateral dimension |D` of the guide portion 60 away from the end of the door side wall 32 and the guide portion 50 close to the end of the door side wall 32 along the direction perpendicular to the door side wall 32 P2 -D` Q1 | is too large, and the guide part 50 and the guide part 60 are arranged loosely in the lateral direction, resulting in an increase in the size of the guide part 50 and the guide part 60 as a whole in the direction perpendicular to the door side wall 32, resulting in an increase in the space of the door body 30 hollowed out in the direction perpendicular to the door side wall 32 due to the installation of the guide part 50 and the guide part 60, thereby reducing the strength of the end of the door body 30 having the guide part 50 and the guide part 60. On the other hand, the manufacturing cost is increased.

[0657] If the guide portion 50 is away from one end of the door side wall 32 and the guide portion 60 is away from one end of the door side wall 32 along the lateral dimension perpendicular to the door side wall 32 | D` P2 -D` Q1 | If the angle is too small, the trajectories of the guide portion 50 and the guide portion 60 are limited to a small range, resulting in a reduction in the maximum angle at which the door body 30 can be opened.

[0658] In some embodiments of the present application, the second guide boundary point Z2 is located on the side of the first guide boundary point H1 close to the door side wall 32. That is, D' P2 <D` Q1 .

[0659] In some embodiments of the present application, the distance between the second guide boundary point Z2 and the first guide boundary point H1 is recorded as |Z2H1|, that is, the length of the line segment Z2H1 is recorded as |Z2H1|.

[0660] In some embodiments of the present application, |Z2H1| is greater than the first relative distance endpoint value. For example, the first relative distance endpoint value is 35 mm, or 35.5 mm.

[0661] In some embodiments of the present application, |Z2H1| is less than the second relative distance endpoint value. For example, the second relative distance endpoint value is 36 mm, 38 mm, or 40 mm.

[0662] In some embodiments of the present application, the angle between the straight line Z2H1 where the second guide boundary point Z2 and the first guide boundary point H1 are located and the door front wall 31 is recorded as the second relative front angle ζ2.

[0663] In some embodiments of the present application, ζ2 is greater than or equal to the first relative front angle endpoint value. For example, the first relative front angle endpoint value is 0°, 0.1°, 0.2°, or 0.3°.

[0664] In some embodiments of the present application, ζ2 is less than the second relative front angle endpoint value. For example, the second relative front angle endpoint value is 0.4°, 0.5°, 1°, 5°, 10°, or 15°.

[0665] In some embodiments of the present application, the angle between the straight line Z2H1 and the door side wall 32 is recorded as the second relative side angle ζ`2.

[0666] In some embodiments of the present application, ζ`2 is greater than the first relative side angle endpoint value. For example, the first relative side angle endpoint value is 82°, 84°, 88°, or 89°.

[0667] In some embodiments of the present application, ζ`2 is less than or equal to the second relative side angle endpoint value. For example, the second relative side angle endpoint value is 89.8°, 89.9°, or 90°.

[0668] As mentioned above, any one of the second relative front angle ζ2 or the second relative side angle ζ`2 and the length |Z2H1| of the line segment Z2H1 jointly define the relative position relationship between the end of the guide portion 50 close to the door side wall 32 and the end of the guide portion 60 away from the door side wall 32, and effectively define the longitudinal dimension of the end of the guide portion 50 close to the door side wall 32 and the end of the guide portion 60 away from the door side wall 32 along the direction perpendicular to the door front wall 31 and the lateral dimension of the end of the guide portion 50 close to the door side wall 32 and the direction perpendicular to the door side wall 32.

[0669] If the longitudinal dimensions of the end of the guide portion 50 close to the door side wall 32 and the end of the guide portion 60 away from the door side wall 32 in the direction perpendicular to the door front wall 31 are too large, when the first guide boundary point H1 is set closer to the door front wall 31 than the second guide boundary point Z2 (D P2 >D Q1 ), the distance between the end of the guide portion 50 close to the door side wall 32 and the door front wall 31 increases, reducing the maximum angle that the door body 30 can open, affecting the user experience.

[0670] When the second guide boundary point Z2 is set closer to the door front wall 31 than the first guide boundary point H1 (D P2 >D Q1 ), the end of the guide portion 50 close to the door side wall 32 is closer to the door front wall 31, and the overall track formed by the guide portion 50 and the guide portion 60 increases in size in a direction perpendicular to the door front wall 31, resulting in an increase in the thickness of the door body 30, resulting in an increase in 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, 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.

[0671] If the lateral dimensions of the end of the guide portion 60 away from the door side wall 32 and the end of the guide portion 50 close to the door side wall 32 in the direction perpendicular to the door side wall 32 are too large, the guide portion 50 and the guide portion 60 are arranged loosely in the lateral direction, resulting in an increase in the overall dimensions of the guide portion 50 and the guide portion 60 in the direction perpendicular to the door side wall 32, resulting in an increase in the space of the door body 30 hollowed out in the direction perpendicular to the door side wall 32 due to the provision of the guide portion 50 and the guide portion 60, thereby reducing the strength of the end of the door body 30 having the guide portion 50 and the guide portion 60. On the other hand, the manufacturing cost is increased.

[0672] If the lateral dimensions of the guide portion 50 away from one end of the door side wall 32 and the guide portion 60 away from the other end of the door side wall 32 in a direction perpendicular to the door side wall 32 are too small, the trajectories of the guide portion 50 and the guide portion 60 are restricted to a small range, resulting in a reduction in the maximum angle at which the door body 30 can be opened.

[0673] In some embodiments of the present application, in the direction perpendicular to the door front wall 31, the distance between the second guide boundary point Z2 and the second guide boundary point H2 is recorded as D Q2 -D P2 .

[0675] In some embodiments of the present application, D Q2 -D P2 Greater than the first relative front distance endpoint value. For example, the first relative front distance endpoint value is 10mm, 15mm, 18mm, or 19mm.

[0676] In some embodiments of the present application, D Q2 -D P2 Less than the second relative front distance endpoint value. For example, the second relative front distance endpoint value is 20 mm, 22 mm, or 25 mm.

[0677] If the longitudinal dimension D of the end of the guide portion 50 close to the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 along the direction perpendicular to the door front wall 31 is Q2 -D P2 If the thickness of the guide portion 50 and the guide portion 60 is too large, the wall thickness between the guide portion 50 and the guide portion 60 will increase, resulting in slow local cooling during the preparation of the guide portion 50 and the guide portion 60, which will easily cause shrinkage deformation and affect the dimensional accuracy of the guide portion 50 and the guide portion 60. On the other hand, the overall track of the guide portion 50 and the guide portion 60 will become wider, the thickness of the door body 30 will increase, and it will not be suitable for ultra-thin door bodies. At the same time, the door body 30 will block the access port more. 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.

[0678] If the longitudinal dimension D of the end of the guide portion 50 close to the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 along the direction perpendicular to the door front wall 31 is Q2 -D P2 If the diameter of the guide portion 50 is too small, the guide portion 50 and the guide portion 60 will be 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 its strength, then 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.

[0679] In addition, D Q2 -D P2 If the angle is too small, the trajectories of the guide portion 50 and the guide portion 60 are restricted to a small range, resulting in a reduction in the maximum angle at which the door body 30 can be opened.

[0680] In some embodiments of the present application, the second guide boundary point Z2 is located on the side of the second guide boundary point H2 close to the door front wall 31, or the second guide boundary point Z2 is located on the side of the second guide boundary point H2 away from the door front wall 31.

[0681] In some embodiments of the present application, the second guide boundary point Z2 is located on a side of the second guide boundary point H2 close to the door front wall 31. Q2 >D P2 .

[0682] In some embodiments of the present application, in the direction perpendicular to the door side wall 32, the distance between the second guide boundary point Z2 and the second guide boundary point H2 is denoted as |D` P2 -D` Q2 |.

On the other hand, the manufacturing cost is increased.

[0687] If the lateral dimension |D` of the guide portion 50 close to the door side wall 32 and the guide portion 60 close to the door side wall 32 along the direction perpendicular to the door front wall 31 P2 -D` Q2 | If the angle is too small, the trajectories of the guide portion 50 and the guide portion 60 are limited to a small range, resulting in a reduction in the maximum angle at which the door body 30 can be opened.

[0688] In some embodiments of the present application, the second guide boundary point Z2 is located on the side of the second guide boundary point H2 close to the door side wall 32. P2 <D` Q2 .

[0689] In some embodiments of the present application, the second guide boundary point Z2 is located on the side of the second guide boundary point H2 away from the door side wall 32. P2 >D` Q2 .

[0690] In some embodiments of the present application, the distance between the second guide boundary point Z2 and the second guide boundary point H2 is recorded as |Z2H2|, that is, the length of the line segment Z2H2 is recorded as |Z2H2|.

[0691] In some embodiments of the present application, |Z2H2| is greater than a first relative distance reference value. For example, the first relative distance reference value is 35 mm, or 35.5 mm.

[0692] In some embodiments of the present application, |Z2H2| is less than the second relative distance reference value. For example, the second relative distance reference value is 36 mm, 38 mm, or 40 mm.

[0693] In some embodiments of the present application, the angle between the straight line Z2H2 where the second guide boundary point Z2 and the second guide boundary point H2 are located and the door front wall 31 is recorded as the third relative front angle ζ3.

[0694] In some embodiments of the present application, ζ3 is greater than a first relative rake angle reference value. For example, the first relative rake angle reference value is 79°, 81°, or 82°.

[0695] In some embodiments of the present application, ζ3 is less than the second relative rake angle reference value. For example, the second relative rake angle reference value is 84°, 86°, 88°, or 90°.

[0696] In some embodiments of the present application, the angle between the straight line Z2H2 and the door side wall 32 is recorded as the third relative side angle ζ`3.

[0697] In some embodiments of the present application, ζ`3 is greater than a first relative side angle reference value. For example, the first relative side angle reference value is 0°, 2°, 4°, or 6°.

[0698] In some embodiments of the present application, ζ`3 is less than the second relative side angle reference value. For example, the second relative side angle reference value is 8°, 10°, 14°, 15°, or 16°.

[0699] In the above, any one of the third relative front angle ζ3 or the third relative side angle ζ`3 and the length of the line segment Z2H2 denoted as |Z2H2| jointly define the relative position relationship between the end of the guide portion 50 close to the door side wall 32 and the end of the guide portion 60 close to the door side wall 32, and effectively define the longitudinal dimension of the end of the guide portion 50 close to the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 along the direction perpendicular to the door front wall 31 and the lateral dimension perpendicular to the door side wall 32.

[0700] If the longitudinal dimension of the guide portion 50 near the door side wall 32 and the guide portion 60 near the door side wall 32 is too large along the direction perpendicular to the door front wall 31, the wall thickness between the guide portion 50 and the guide portion 60 increases, resulting in slow local cooling during the preparation of the guide portion 50 and the guide portion 60, which is prone to shrinkage deformation and affects the dimensional accuracy of the guide portion 50 and the guide portion 60. On the other hand, it will cause the overall track of the guide portion 50 and the guide portion 60 to become wider, the thickness of the door body 30 to increase, and it cannot be applied to ultra-thin door bodies, and at the same time, the door body 30 will block the access port more; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the horizontal width of the drawer, resulting in the drawer not being able to effectively use the horizontal space of the storage room.

[0701] If the longitudinal dimensions of the guide portion 50 near the door side wall 32 and the guide portion 60 near the door side wall 32 are too small in the direction perpendicular to the door front wall 31, 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 matched with the first shaft 41 and the guide portion 60 matched 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. However, 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 is easy to 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, then 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.

[0702] In addition, the longitudinal dimensions of the guide portion 50 at one end near the door side wall 32 and the guide portion 60 at one end near the door side wall 32 in a direction perpendicular to the door front wall 31 are too small, and the trajectories of the guide portion 50 and the guide portion 60 are limited to a small range, resulting in a reduction in the maximum angle that the door body 30 can open.

[0703] If the lateral dimensions of the guide portion 50 and the guide portion 60 near the door side wall 32 are too large along the direction perpendicular to the door front wall 31, the dimensions of the guide portion 50 and the guide portion 60 as a whole along the direction perpendicular to the door side wall 32 increase, resulting in an increase in the space hollowed out of the door body 30 along the direction perpendicular to the door side wall 32 due to the provision of the guide portion 50 and the guide portion 60, thereby reducing the strength of the end of the door body 30 having the guide portion 50 and the guide portion 60. On the other hand, the manufacturing cost is increased.

[0704] If the lateral dimensions of the guide portion 50 and the guide portion 60 near one end of the door side wall 32 and the direction perpendicular to the door front wall 31 are too small, the trajectories of the guide portion 50 and the guide portion 60 are restricted to a small range, resulting in a reduction in the maximum angle at which the door body 30 can be opened.

[0705] In some embodiments of the present application, in the direction perpendicular to the door front wall 31, the distance between the first guide boundary point Z1 and the second guide boundary point H2 is recorded as D Q2 -D P1 .

[0706] D Q2 -D P1 is the distance D between the second guide boundary point H2 and the door front wall 31 Q2 The distance D between the first guide boundary point Z1 and the door front wall 31 P1 The difference.

[0708] In some embodiments of the present application, D Q2 -D P1 Smaller than the second relative front distance reference value. For example, the second relative front distance reference value is 13 mm, 15 mm, 17 mm, 19 mm, or 20 mm.

[0709] If the longitudinal dimension D of the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 along the direction perpendicular to the door front wall 31 is Q2 -D P1If the thickness of the guide portion 50 and the guide portion 60 is too large, the wall thickness between the guide portion 50 and the guide portion 60 will increase, resulting in slow local cooling during the preparation of the guide portion 50 and the guide portion 60, which will easily cause shrinkage deformation and affect the dimensional accuracy of the guide portion 50 and the guide portion 60.

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.

[0710] If the longitudinal dimension D of the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 along the direction perpendicular to the door front wall 31 is Q2 -D P1 If the diameter of the guide portion 50 is too small, the guide portion 50 and the guide portion 60 will be 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.

[0717] In some embodiments of the present application, D P1 -D` Q2 Smaller than the second opposite side distance reference value. For example, the second opposite side distance reference value is 20 mm, 20.5 mm, or 20.7 mm.

[0718] If the guide portion 50 is away from the door side wall 32 and the guide portion 60 is close to the door side wall 32 along the lateral dimension D' perpendicular to the door front wall 31 P1 -D` Q2 If the first side edge W (door corner) is too large, the first side edge W (door corner) will extend beyond the original position during the opening of the refrigerator, which may easily cause the first side edge W to interfere with the storage cabinet 100, and the door body 30 cannot be opened further. In order to allow the door body 30 to be opened to a larger angle in the storage cabinet 100, a larger gap needs to be reserved between the closed door body 30 and the storage cabinet 100 to avoid the first side edge W (door corner) from interfering with the storage cabinet 100. However, the larger gap reserved above causes the door body 30 to be unable to effectively cover the cabinet 10, affecting the overall appearance of the refrigerator.

[0719] If the guide portion 50 is away from the door side wall 32 and the guide portion 60 is close to the door side wall 32 along the lateral dimension D' perpendicular to the door front wall 31 P1 -D` Q2 If the size is too small, the trajectories of the guide portion 50 and the guide portion 60 are restricted to a small range, resulting in a reduction in the inward displacement of the door body 30, which collides with the storage cabinet 100 near the first side edge W (door corner), making it impossible for the door body 30 to be effectively opened.

[0720] In some embodiments of the present application, the distance between the first guide boundary point Z1 and the second guide boundary point H2 is |Z1H2|, that is, the length of the line segment Z1H2 is recorded as |Z1H2|.

[0721] In some embodiments of the present application, |Z1H2| is greater than the first relative distance control value. For example, the first relative distance control value is 20 mm, 21 mm, or 22 mm.

[0722] In some embodiments of the present application, |Z1H2| is less than the second relative distance control value. For example, the second relative distance control value is 24 mm, 26 mm, 28 mm, or 29 mm.

[0723] In some embodiments of the present application, the angle between the straight line Z1H2 where the first guide boundary point Z1 and the second guide boundary point H2 are located and the door front wall 31 is recorded as the fourth relative front angle ζ4.

[0725] In some embodiments of the present application, ζ4 is less than the second relative rake angle comparison value. For example, the second relative rake angle comparison value is 32°, 36°, 40°, or 44°.

[0726] In some embodiments of the present application, the angle between the straight line Z1H2 and the door side wall 32 is recorded as the fourth relative side angle ζ`4.

[0727] In some embodiments of the present application, ζ`4 is greater than the first relative side angle comparison value. For example, the first relative side angle comparison value is 53°, 55°, or 57°.

[0728] In some embodiments of the present application, ζ`4 is less than the second relative side angle comparison value. For example, the second relative side angle comparison value is 60°, 62°, 64°, or 66°.

[0729] As mentioned above, any one of the fourth relative front angle ζ4 or the fourth relative side angle ζ`4 and the length |Z1H2| of the line segment Z1H2 jointly define the relative position relationship between the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 close to the door side wall 32, and effectively define the longitudinal dimension of the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 along the direction perpendicular to the door front wall 31 and the lateral dimension of the end of the guide portion 50 away from the door side wall 32 and the direction perpendicular to the door side wall 32.

[0730] If the longitudinal dimension of the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 in the direction perpendicular to the door front wall 31 is too large, the wall thickness between the guide portion 50 and the guide portion 60 increases, resulting in slow local cooling during the preparation of the guide portion 50 and the guide portion 60, which is prone to shrinkage deformation and affects the dimensional accuracy of the guide portion 50 and the guide portion 60. On the other hand, it will cause the overall track of the guide portion 50 and the guide portion 60 to become wider, the thickness of the door body 30 to increase, and it cannot be applied to ultra-thin door bodies, and at the same time, the door body 30 will block the access port more; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the horizontal width of the drawer, resulting in the drawer not being able to effectively use the horizontal space of the storage room.

[0731] If the longitudinal dimension of the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 in the direction perpendicular to the door front wall 31 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 matched with the first shaft 41 and the guide portion 60 matched 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. However, 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 is easy to 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, then 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.

[0732] If the lateral dimensions of the end of the guide portion 50 away from the door side wall 32 and the end of the guide portion 60 close to the door side wall 32 in the direction perpendicular to the door front wall 31 are too large, the first side edge W (door corner) will exceed the original position more during the opening of the refrigerator, which may easily cause the first side edge W to interfere with the storage cabinet 100, and the door body 30 cannot continue to open. In order to allow the door body 30 to open to a larger angle in the storage cabinet 100, a larger gap needs to be reserved between the closed door body 30 and the storage cabinet 100 to avoid the first side edge W (door corner) from interfering with the storage cabinet 100. However, the larger gap reserved above causes the door body 30 to be unable to effectively cover the cabinet 10, affecting the overall appearance of the refrigerator.

[0733] If the lateral dimensions of the guide portion 50 at one end away from the door side wall 32 and the guide portion 60 at one end close to the door side wall 32 in a direction perpendicular to the door front wall 31 are too small, the trajectories of the guide portion 50 and the guide portion 60 are restricted to a small range, resulting in a reduction in the inward displacement of the door body 30, and a collision with the storage cabinet 100 near the first side edge W (door corner), so that the door body 30 cannot be effectively opened.

[0734] In some embodiments of the present application, in the direction perpendicular to the door front wall 31, the distance between the third guide boundary point Z3 and the third guide boundary point H3 is recorded as D Q3 -D P3 .

[0735] D Q3 -D P3 is the distance D between the third guide boundary point H3 and the door front wall 31 Q3 The distance D between the third guide boundary point Z3 and the door front wall 31 P3 The difference.

[0736] In some embodiments of the present application, D Q3 -D P3Greater than the first relative front distance control value. For example, the first relative front distance control value is 4mm, 7mm, 9mm, or 10mm.

[0737] In some embodiments of the present application, D Q3 -D P3 Less than the second relative front distance control value. For example, the second relative front distance control value is 12 mm, 14 mm, 15 mm, or 16 mm.

[0738] If the longitudinal dimension D between the maximum distance point Z3 between the guide portion 50 and the door front wall 31 and the maximum distance point H3 between the guide portion 60 and the door front wall 31 is Q3 -D P3 If the thickness of the guide portion 50 and the guide portion 60 is too large, the wall thickness between the guide portion 50 and the guide portion 60 will increase, resulting in slow local cooling during the preparation of the guide portion 50 and the guide portion 60, which will easily cause shrinkage deformation and affect the dimensional accuracy of the guide portion 50 and the guide portion 60. On the other hand, the overall track of the guide portion 50 and the guide portion 60 will become wider, the thickness of the door body 30 will increase, and it will not be suitable for ultra-thin door bodies. At the same time, the door body 30 will block the access port more. 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.

[0739] If the longitudinal dimension D between the maximum distance point Z3 between the guide portion 50 and the door front wall 31 and the maximum distance point H3 between the guide portion 60 and the door front wall 31 is Q3 -D P3 If the diameter of the guide portion 50 is too small, the guide portion 50 and the guide portion 60 will be 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 its strength, then 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.

[0740] In some embodiments of the present application, the third guide boundary point Z3 is located on a side of the third guide boundary point H3 close to the door front wall 31 .

[0741] In the direction perpendicular to the door front wall 31, the distance between the third guide boundary point Z3 and the third guide boundary point H3 is the distance D between the third guide boundary point H3 and the door front wall 31. Q3 The distance D between the third guide boundary point Z3 and the door front wall 31 P3 The distance difference.

[0742] In some embodiments of the present application, in the direction perpendicular to the door side wall 32, the distance between the third guide boundary point Z3 and the third guide boundary point H3 is recorded as |D` P3 -D` Q3 |.

[0743] Above | D` P3 -D` Q3 | is the distance D' between the third guide boundary point Z3 and the door side wall 32 P3 The distance D' between the third guide boundary point H3 and the door side wall 32 Q3 The absolute value of the difference.

[0744] In some embodiments of the present application, |D` P3 -D` Q3 |Greater than the first opposite side distance control value. For example, the first opposite side distance control value is 0mm, 0.1mm, or 0.2mm.

[0745] In some embodiments of the present application, |D` P3 -D` Q3 | is smaller than the second opposite side distance control value. For example, the second opposite side distance control value is 1 mm, 2 mm, 3 mm, 4 mm, or 5 mm.

[0746] If the lateral dimension between the maximum distance point Z3 between the guide portion 50 and the door front wall 31 and the maximum distance point H3 between the guide portion 60 and the door front wall 31 | D` P3 -D` Q3 |If it is too large, the area corresponding to the guide part 50 and the guide part 60 will have a thick wall on one side and a thin wall on the other side. The wall thickness between the guide part 50 and the guide part 60 varies greatly. During manufacturing, the small wall thickness is prone to insufficient material and lead to material shortage, while the large wall thickness is prone to slow cooling, and shrinkage deformation affects the accuracy of the guide part 50 and the guide part 60.

[0747] If the lateral dimension between the maximum distance point Z3 between the guide portion 50 and the door front wall 31 and the maximum distance point H3 between the guide portion 60 and the door front wall 31 | D` P3 -D` Q3| Being arranged within the above small range, the wall thickness between the guide portion 50 and the guide portion 60 can be limited within a small range, which ensures the relative independence and integrity of the guide portion 50 and the guide portion 60 on the one hand. On the other hand, it facilitates molding to ensure the accuracy of the guide portion 50 and the guide portion 60. Furthermore, during the opening process of the door body 30, the moving direction of the first axis 41 relative to the guide portion 50 always points to the side wall of the first body and the access opening, while the moving direction of the second axis 42 relative to the guide portion 60 always points to the side wall of the first body and the access opening, so that the door body 30 maintains the displacement moving inward and forward, thereby reducing the restriction of the storage cabinet 100 on the opening angle of the door body 30, so that the door body 30 can be opened at a larger angle.

[0748] In some embodiments of the present application, the third guide boundary point Z3 is located on the side of the third guide boundary point H3 close to the door side wall 32. That is, D' P3 <D` Q3 .

[0749] In some embodiments of the present application, the third guide boundary point Z3 is located on the side of the third guide boundary point H3 away from the door side wall 32. That is, D' P3 >D` Q3 .

[0750] In some embodiments of the present application, the distance between the third guide boundary point Z3 and the third guide boundary point H3 is |Z3H3|, that is, the length of the line segment Z3H3 is recorded as |Z3H3|.

[0751] In some embodiments of the present application, |Z3H3| is greater than the first relative distance limit. For example, the first relative distance limit is 4 mm, 6 mm, or 8 mm.

[0752] In some embodiments of the present application, |Z3H3| is less than the second relative distance extreme value. For example, the second relative distance extreme value is 12 mm, 14 mm, 16 mm, or 17 mm.

[0753] In some embodiments of the present application, the angle between the straight line Z3H3 where the third guide boundary point Z3 and the third guide boundary point H3 are located and the door front wall 31 is recorded as the fifth relative front angle ζ5.

[0754] In some embodiments of the present application, ζ5 is greater than the first relative front angle extreme value. For example, the first relative front angle extreme value is 82°, 85°, 87°, or 88°.

[0755] In some embodiments of the present application, ζ5 is less than or equal to the second relative front angle extreme value. For example, the second relative front angle extreme value is 89.5° or 90°.

[0756] In some embodiments of the present application, the angle between the straight line Z3H3 and the door side wall 32 is recorded as the fifth relative side angle ζ`5.

[0757] In some embodiments of the present application, ζ`5 is greater than or equal to the first relative side angle extreme value. For example, the first relative side angle extreme value is 0°, 0.5°, 1°, or 1.2°.

[0758] In some embodiments of the present application, ζ`5 is less than the second relative side angle extreme value. For example, the second relative side angle extreme value is 2°, 5°, 8°, or 10°.

[0759] As mentioned above, any one of the fifth relative front angle ζ5 or the fifth relative side angle ζ`5 and the length |Z3H3| of the line segment Z3H3 jointly define the relative position relationship between the point Z3 on the guide portion 50 at the maximum distance from the door front wall 31 and the point H3 on the guide portion 60 at the maximum distance from the door front wall 31, and effectively define the longitudinal dimension of the point Z3 on the guide portion 50 at the maximum distance from the door front wall 31 and the point H3 on the guide portion 60 at the maximum distance from the door front wall 31 along the direction perpendicular to the door front wall 31 and the lateral dimension in the direction perpendicular to the door side wall 32.

[0760] If the longitudinal dimension between the maximum distance point Z3 between the guide part 50 and the door front wall 31 and the maximum distance point H3 between the guide part 60 and the door front wall 31 is too large, the wall thickness between the guide part 50 and the guide part 60 increases, resulting in slow local cooling during the preparation of the guide part 50 and the guide part 60, which is prone to shrinkage deformation and affects the dimensional accuracy of the guide part 50 and the guide part 60. On the other hand, it will cause the overall track of the guide part 50 and the guide part 60 to become wider, the thickness of the door body 30 to increase, and it cannot be applied to ultra-thin door bodies, and at the same time, the door body 30 will block the access port more; and in order to ensure that the drawer installed in the storage room can be pulled out, it is necessary to reduce the horizontal width of the drawer, resulting in the drawer not being able to effectively use the horizontal space of the storage room.

[0761] If the longitudinal dimension between the maximum point Z3 of the guide portion 50 and the door front wall 31 and the maximum point H3 of the guide portion 60 and the door front wall 31 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 matched with the first shaft 41 and the guide portion 60 matched 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. However, 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 may 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, then 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.

[0762] If the lateral dimension between the maximum point Z3 on the guide portion 50 and the door front wall 31 and the maximum point H3 on the guide portion 60 and the door front wall 31 is too large, the area corresponding to the guide portion 50 and the guide portion 60 will have a thick wall on one side and a thin wall on the other side, and the wall thickness variation range between the guide portion 50 and the guide portion 60 is large. During manufacturing, the small wall thickness is prone to dissipation and resulting in material shortages, while the large wall thickness is prone to slow cooling, and shrinkage deformation affects the accuracy of the guide portion 50 and the guide portion 60.

[0763] If the lateral dimension between the maximum point Z3 between the guide part 50 and the door front wall 31 and the maximum point H3 between the guide part 60 and the door front wall 31 is set within the above small range, the wall thickness between the guide part 50 and the guide part 60 can be limited within a small range, which ensures the relative independence and integrity of the guide part 50 and the guide part 60 on the one hand. On the other hand, it is convenient for molding to ensure the accuracy of the guide part 50 and the guide part 60. Furthermore, during the opening process of the door body 30, the moving direction of the first axis 41 relative to the guide part 50 always points to the side wall of the first body and the access opening, and the moving direction of the second axis 42 relative to the guide part 60 always points to the side wall of the first body and the access opening, so that the door body 30 maintains the displacement moving inward and forward, thereby reducing the restriction of the storage cabinet 100 on the opening angle of the door body 30, so that the door body 30 can be opened at a larger angle.

[0764] In some embodiments of the present application, when the opening angle of the door body 30 is G7=90°, the first center axis P is located at the seventh guide point P7 of the guide trajectory line S, and the second center axis Q is located at the seventh guide point Q7 on the guide trajectory line K.

[0765] In some embodiments of the present application, the seventh guide point Q7 is located on a side of the seventh guide point P7 away from the door side wall 32 and the door front wall 31 .

[0766] The eighth guiding point P8 is located on a side of the seventh guiding point P7 close to the door side wall 32 and the door front wall 31 .

[0767] The seventh guiding point P7 is located on a side of the straight line Q7P8 where the seventh guiding point Q7 and the eighth guiding point P8 are located, close to the door side wall 32 .

[0768] In some embodiments of the present application, ∠Q7P7P8 is greater than the first angle reference value. For example, the first angle reference value is 160°, 162°, or 164°.

[0769] In some embodiments of the present application, ∠Q7P7P8 is less than the second angle reference value. For example, the second angle reference value is 166°, 168°, 170°, or 171°.

[0770] The above ∠Q7P7P8 angle range defines the relative positions of the seventh guide point P7, the eighth guide point P8 and the seventh guide point Q7, which, on the one hand, makes the P7P8 segment of the guide trajectory line S extending from P7 to P8 smoother than the straight line trajectory of the tangent line at the point P7 on the guide trajectory line S. On the other hand, the above definition allows the door body 30 to maintain a greater inward and forward movement efficiency when it continues to open from 90°, thereby reducing the influence of the storage cabinet 100 on the door body 30, so that the maximum angle that the door body 30 of the refrigerator accommodated in the storage cabinet 100 can be opened is larger, which is convenient for users to take and put items.

[0771] In some embodiments of the present application, the straight line where the seventh guide point P7 and the eighth guide point P8 are located is recorded as straight line P7P8, and the angle between the straight line P7P8 and the door front wall 31 is recorded as the guide forward tilt angle μ P The angle between the straight line P7P8 and the door side wall 32 is recorded as the guide roll angle μ` P .

[0772] The straight line between the seventh guide point Q7 and the seventh guide point P7 is recorded as straight line P7Q7; the angle between the straight line P7Q7 and the door front wall 31 is recorded as the first forward tilt angle μ PQ The angle between the straight line P7Q7 and the door side wall 32 is recorded as the first tilt angle μ` PQ .

[0773] In some embodiments of the present application, the guiding front tilt angle μ P ≥First rake angle μ PQ .

[0774] In some embodiments of the present application, μ PQ is greater than the first reference value of the front tilt angle. For example, the first reference value of the front tilt angle is 62°, 64°, or 66°.

[0775] In some embodiments of the present application, μ PQ is smaller than the second reference value of the front tilt angle. For example, the second reference value of the front tilt angle is 68° or 70°.

[0776] In some embodiments of the present application, μ P is greater than the first guide front inclination angle reference value. For example, the first guide front inclination angle reference value is 79° or 80°.

[0777] In some embodiments of the present application, μ P is smaller than the second guide front inclination angle reference value. For example, the second guide front inclination angle reference value is 82°, 85°, or 88°.

[0778] The first rake angle μ PQ , Guidance forward tilt angle μ PThe definition of the relative relationship between the seventh guide point P7, the eighth guide point P8 and the seventh guide point Q7 defines the relative positions, on the one hand, making the P7P8 segment of the guide trajectory line S extending from P7 to P8 smoother than the straight line trajectory of the tangent line at the point P7 on the guide trajectory line S. On the other hand, the above definition enables the door body 30 to maintain a greater inward and forward movement efficiency when it continues to open from 90°, thereby reducing the influence of the storage cabinet 100 on the door body 30, so that the maximum angle that the door body 30 of the refrigerator accommodated in the storage cabinet 100 can be opened is larger, which is convenient for users to take and put items.

[0779] In some embodiments of the present application, the first roll angle μ` PQ ≥Guide forward tilt angle μ P .

[0780] In some embodiments of the present application, μ` P is greater than the first guide roll angle reference value. For example, the first guide roll angle reference value is 4°, 6°, or 8°.

[0781] In some embodiments of the present application, μ` P is smaller than the second guide roll angle reference value. For example, the second guide roll angle reference value is 9° or 11°.

[0782] In some embodiments of the present application, μ` PQ is greater than the first roll angle reference value. For example, the first roll angle reference value is 20°, 21°, 22°, or 23°.

[0783] In some embodiments of the present application, μ` PQ is smaller than the second roll angle reference value. For example, the second roll angle reference value is 24°, 27°, or 30°.

[0784] The above guide roll angle μ` P , the first roll angle μ` PQ The definition of the relative relationship between the seventh guide point P7, the eighth guide point P8 and the seventh guide point Q7 defines the relative positions, on the one hand, making the P7P8 segment of the guide trajectory line S extending from P7 to P8 smoother than the straight line trajectory of the tangent line at the point P7 on the guide trajectory line S. On the other hand, the above definition enables the door body 30 to maintain a greater inward and forward movement efficiency when it continues to open from 90°, thereby reducing the influence of the storage cabinet 100 on the door body 30, so that the maximum angle that the door body 30 of the refrigerator accommodated in the storage cabinet 100 can be opened is larger, which is convenient for users to take and put items.

[0785] It should be noted that the angle indicated in the present invention refers to a line-line angle, a line-plane angle, or a plane-plane angle, and the "angle" ranges from any value between 0° and 90°.

[0786] In some embodiments of the present application, the second axis 42 is located on a side of the first axis 41 away from the second side edge N.

[0787] In some embodiments of the present application, the guide portion 60 is located on a side of the guide portion 50 away from the first side edge W.

[0788] In some embodiments of the present application, the first shaft 41 first moves relative to the guide portion 50 toward a side away from the door front wall 31 and close to the door side wall 32 , and then moves toward a side close to the door front wall 31 and the door side wall 32 .

[0789] In some embodiments of the present application, the second shaft 42 moves relative to the guide portion 60 first to a side away from the door front wall 31 and close to the door side wall 32, and then moves to a side close to the door front wall 31 and the door side wall 32.

[0790] The first axis 41 moves relative to the guide portion 50 and the second axis 42 moves relative to the guide portion 60 so that the door body 30 can move a certain distance inward (toward the direction close to the second body side wall) while rotating, so as to compensate for the distance that the first side edge W moves outward caused by the simple rotational movement of the door body 30, thereby controlling the distance that the first side edge W exceeds the first body side wall, so as to limit the distance that the first side edge W exceeds the first body side wall to within the range of the gap between the storage cabinet 100 and the first body side wall, thereby preventing the first side edge W from colliding with the storage cabinet 100 and causing the door body 30 to be unable to open.

[0791] In some embodiments of the present application, the distance between the first central axis P and the door front wall 31 when the door body 30 is in a closed state is equal to the distance between the first central axis P and the door front wall 31 when the door body 30 is opened to 90°.

[0792] In some embodiments of the present application, the distance between the starting guiding point P0 on the guiding trajectory line S and the door front wall 31 is equal to the distance between the sixth guiding point P6 and the door front wall 31 .

[0793] When the first central axis P moves to the sixth guide point P6, the door body 30 opens to 90°.

[0794] In some embodiments of the present application, the straight line P0P6 where the starting guiding point P0 and the sixth guiding point P6 on the guiding trajectory line S are located is parallel to the door front wall 31 .

[0795] In some embodiments of the present application, when the door body 30 is in a closed state, the straight line P0P6 where the starting guide point P0 and the sixth guide point P6 on the guide trajectory line S are located is parallel to the plane where the access port is located.

[0796] In some embodiments of the present application, when the door body 30 is in a closed state, a straight line P0P6 where a starting guide point P0 and a sixth guide point P6 on the guide trajectory line S are located is perpendicular to the first body side wall.

[0797] 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 reference objects for description.

[0798] In some embodiments of the present application, in the projection of the plane where the top wall of the box body 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 5-Figure 14 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.

[0799] In some embodiments of the present application, the first center axis P moves along the guide trajectory line S, and the second center axis Q moves along the guide trajectory line K, so that the door body 30 can move a certain distance inward (in the direction close to 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.

[0800] 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 parallel to the top wall of the box body 10); 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. Since the first hinge member having the first axis 41 and the second axis 42 is fixed to the box body 10, and the second hinge member having the guide portion 60 and the guide portion 50 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 60 and guide portion 50) 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.

[0801] 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 60 and the guide portion 50) 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. The description of the relative movement of the present invention is described as the relative movement in a two-dimensional plane.

[0802] like Figure 5As shown, in some embodiments of the present application, when the door body 30 is in a closed state, the first center axis P is located at the starting guide point P0 of the guide trajectory line S, and the second center axis Q is located at the starting guide point Q0 of the guide trajectory line K.

[0803] In some embodiments of the present application, when the door body 30 is in a closed state, the first shaft 41 is located at an end of the guide portion 50 away from the door side wall 32 .

[0804] In some embodiments of the present application, when the door body 30 is in a closed state, the second shaft 42 is located at an end of the guide portion 60 away from the door side wall 32 .

[0805] In some embodiments of the present application, when the door body 30 is in a closed state, the first shaft 41 is located at an end of the guide portion 50 away from the door side wall 32 , and the second shaft 42 is located at an end of the guide portion 60 away from the door side wall 32 .

[0806] The second shaft 42 is located on a side of the first shaft 41 close to the door front wall 31 and away from the door side wall 32 .

[0807] In some embodiments of the present application, when the door body 30 is closed, relative to the door rear wall 33 , the first axis 41 and the second axis 42 are both close to the door front wall 31 .

[0808] In some embodiments of the present application, Figure 6-Figure 14 As shown, under the constraints of the guide portion 50 and the first axis 41, the guide portion 60 and the second axis 42, the refrigerator is opened at an eighth angle G8>90° (G max = G8) is used as an example. In the process of the door body 30 opening from the closed state to the eighth angle G8, when the door body 30 rotates to open to a specific angle, the relative position of the first shaft 41 relative to the guide portion 50 and the relative position of the second shaft 42 relative to the guide portion 60 are as follows:

[0809] In the following description, Indicates the opening angle of the door body 30. The opening angle when the door body 30 is closed The opening angle of the door 30 when it is opened relative to the box body 10 to open the access opening Is a positive number.
