Description

[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on May 21, 2024, with application number 202421117575.7 and application name “Refrigerator”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present disclosure relate to the technical field of household appliances, and in particular to a refrigerator. Background Art

[0003] At present, flush-mounted refrigerators have attracted wide attention. A flush-mounted refrigerator refers to a refrigerator that can be embedded in a cabinet, and the distance between the outer wall of the refrigerator and the inner wall of the cabinet is usually within 5 mm, and the front panel of the refrigerator door is approximately flush with the front panel of the cabinet.

[0004] In the related art, a flush-mounted refrigerator generally includes a cabinet, a door body, and a biaxial hinge. The cabinet is configured with a refrigeration compartment having a take-in and take-out opening. The door body is connected to the cabinet through a biaxial hinge for opening or closing the take-in and take-out opening. A first track groove and a second track groove are provided at the top or bottom end of the door body. The biaxial hinge includes a hinge plate, a first hinge shaft, and a second hinge shaft. The hinge plate is connected to the cabinet. The first hinge shaft and the second hinge shaft are both connected to the hinge plate and are slidably disposed in the first track groove and the second track groove, respectively. When a pulling force or a pushing force is applied to the door body, the first hinge shaft slides in the first track groove, and the second hinge shaft slides in the second track groove, so that the axis point of the door body when rotating relative to the cabinet moves, thereby preventing the door body from interfering with the cabinet.

[0005] However, when using a dual-axis hinge, due to the limited thickness of the door body, the extension track of the first track groove and the second track groove is limited, the front panel of the door body is flush with the cabinet, and a gap of 2-4mm is reserved on both sides of the door body. The maximum opening angle of the door body is 90°-105°, and the maximum opening angle of the door body cannot be further increased. Moreover, when the door opening angle is the maximum opening angle, in the horizontal direction parallel to the plane where the access port is located, due to the limitations of the first track groove and the second track groove, the distance that the door body moves relative to the box body toward the outside of the box body is small, so that the door body will block the access port, causing inconvenience in taking and putting items.

[0006] In order to solve the above technical problems, the inventor tried to apply the hinges of storage cabinets in the home furnishing field to flush-mounted refrigerators. However, for refrigerators equipped with hinges in the related art, the front panel of the door body is flush with the cabinet, and a gap of 2-4 mm is reserved on both sides of the door body. The maximum opening angle of the door body is 90°~114°, and the maximum opening angle of the door body cannot be further increased. Moreover, when the door opening angle is the maximum opening angle, the door body will still block the access port, and there is still the problem of inconvenience in taking and putting items. Utility Model Content

[0007] The disclosed embodiments provide a refrigerator that can solve the technical problems that the opening angle of a door body cannot be further increased, and that the access opening is blocked when the door body is at the maximum opening angle, causing inconvenience in taking and placing items.

[0008] In a first aspect, an embodiment of the present disclosure provides a refrigerator, the refrigerator comprising:

[0009] A box body, which is configured with a storage chamber, the box body having a box front wall located at the front side, and a box side wall connected to the box front wall;

[0010] A door body, used for opening or closing the storage chamber;

[0011] A hinge assembly, which connects the box body and the door body, and the hinge assembly includes:

[0012] A mounting seat connected to the front wall of the box;

[0013] A first rod, a first end of which is rotatably connected to the mounting seat via a first hinge shaft;

[0014] A second rod, a first end of which is rotatably connected to the mounting seat via a second hinge shaft, wherein the axis center point of the second hinge shaft is closer to the front wall of the box and closer to the center of the storage chamber than the axis center point of the first hinge shaft;

[0015] a third rod, wherein a middle portion thereof is rotatably connected to the second end of the first rod via a third hinge shaft, and a first end of the third rod is rotatably connected to the middle portion of the second rod via a fourth hinge shaft;

[0016] a fourth rod, a first end of which is rotatably connected to the second end of the second rod via a fifth hinge shaft;

[0017] a fifth rod, which is fixedly connected to the door body, wherein the first end of the fifth rod is rotatably connected to the second end of the third rod via a sixth hinge shaft; and the second end of the fifth rod is rotatably connected to the second end of the fourth rod via a seventh hinge shaft;

[0018] Wherein, the mounting seat, the first rod, the second rod, the third rod, the fourth rod and the fifth rod form a six-link mechanism;

[0019] When a pulling force is applied to the door body and the door body is opened from a closed state, the fifth rod drives the third rod and the fourth rod, so that the third rod rotates in a first direction relative to the fifth rod, and the fourth rod rotates in the first direction relative to the fifth rod; the third rod drives the first rod and the second rod, so that the first rod rotates in a second direction relative to the mounting seat, and the second rod rotates in the second direction relative to the mounting seat; the fourth rod drives the second rod, so that the second rod rotates in the second direction relative to the mounting seat; wherein the second direction is opposite to the first direction;

[0020] When a thrust is applied to the door body and the door body is closed, the fifth rod drives the third rod and the fourth rod, so that the third rod rotates in the second direction relative to the fifth rod, and the fourth rod rotates in the second direction relative to the fifth rod; the third rod drives the first rod and the second rod, so that the first rod rotates in the first direction relative to the mounting seat, and the second rod rotates in the first direction relative to the mounting seat; the fourth rod drives the second rod, so that the second rod rotates in the first direction relative to the mounting seat;

[0021] A ratio of a distance between an axis point of the second hinge axis and an axis point of the fourth hinge axis to a distance between an axis point of the fourth hinge axis and an axis point of the sixth hinge axis is a second ratio, and the second ratio is less than 1.0.

[0022] The refrigerator in the embodiment of the present application sets the second ratio to be less than 1.0, which is beneficial to increase the movement of the main trajectory point in the horizontal direction toward the inside of the refrigerator, thereby facilitating increasing the movement of the door body in the horizontal direction toward the inside of the refrigerator during the process of opening the door body, thereby preventing the door body from colliding with the cabinet.

[0096] Hereinafter, embodiments of the present disclosure 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.

[0097] refer to Figure 1 , Figure 2 and Figure 3 , the refrigerator of the embodiment of the present disclosure may include a cabinet 100 having a storage chamber, a door body 200 connected to the cabinet 100 to open and close the storage chamber, and a refrigeration device that provides coldness to the storage chamber.

[0098] Exemplarily, the box body 100 may include a box liner, a box shell and a first heat-insulating layer. The box liner is used to form a storage room. The storage room is used to store items such as food. The storage room may be provided with a take-in and put-out opening, through which a user can put items into or take items out of the storage room. The box shell may be connected to the outside of the box liner to form the appearance of a refrigerator. The first heat-insulating layer may be filled between the box liner and the box shell to block heat transfer between the storage room and the external space of the box body 100.

[0099] In some embodiments of the present disclosure, the box 100 may be configured with multiple storage chambers. The multiple storage chambers may include a refrigerating chamber and a freezing chamber. The internal temperature of the refrigerating chamber may be maintained between about 0°C and 5°C to store items in a refrigerated mode. The internal temperature of the freezing chamber may be maintained between about -30°C and 0°C to store items in a frozen mode. In addition, the multiple storage chambers may also include other chambers, such as a vacuum chamber, a temperature-changing chamber, etc., which will not be described in detail in the embodiments of the present disclosure.

[0100] In some embodiments of the present disclosure, the refrigerator and the freezer can be arranged in the height direction of the refrigerator. For example, the refrigerator can be located above the freezer. In other embodiments of the present disclosure, the refrigerator and the freezer can also be arranged in other ways, for example, the refrigerator and the freezer can also be arranged in the width direction of the refrigerator.

[0101] Exemplarily, the door body 200 may include a door shell, a door liner, and a second insulation layer. When the door body 200 is in a closed state, the door liner faces the storage chamber. The door shell may be connected to the side of the door liner facing away from the storage chamber to form the appearance of the refrigerator. The second insulation layer may be filled between the door shell and the door liner to block heat transfer between the storage chamber and the external space of the door body 200 when the door body 200 is closed.

[0102] The door body 200 may be connected to the box body 100 via a hinge assembly 300. For example, the access opening of the storage chamber may be formed at the front side of the box body 100, and the door body 200 may be connected to the front side of the box body 100 via the hinge assembly 300, so that the door body 200 can rotate relative to the box body 100, thereby opening or closing the access opening of the storage chamber. When the door body 200 is opened, the user can put in or take out items through the access opening. When the door body 200 is closed, the items can be placed in the storage chamber for low-temperature storage.

[0103] The number of door bodies 200 can be set corresponding to the number of storage rooms. Figure 1 As shown, the cabinet can be configured with two storage chambers, and the two storage chambers can be arranged along the width direction of the refrigerator. Each storage chamber can be provided with a corresponding door body 200. For example Figure 2 As shown, the cabinet can be configured with two storage chambers, and the two storage chambers can be arranged along the height direction of the refrigerator. Each storage chamber can be provided with two doors 200, and the two doors 200 are connected to the cabinet 100 through hinge assemblies 300, respectively. The two doors 200 can rotate in opposite directions relative to the cabinet 100 to open or close the storage chamber. Figure 3As shown, the box body can be constructed with two storage rooms, and the two storage rooms can be arranged in the height direction of the refrigerator. The storage room located above the refrigerator can be provided with two door bodies 200, and the two door bodies 200 are respectively connected to the box body 100 through hinge assemblies 300. The two door bodies 200 can rotate in opposite directions relative to the box body 100 to open or close the storage room located above.

[0104] The same door body 200 can be connected to the refrigerator via one hinge assembly 300. Alternatively, the same door body 200 can also be connected to the refrigerator via multiple hinge assemblies 300. Taking the example of the same door body 200 being connected to the cabinet 100 via two hinge assemblies 300, the hinge assembly 300 can be arranged at the top of the door body 200, for example Figures 1 to 3 The hinge assembly 300 may also be disposed at the bottom of the door body 200, for example Figures 1 to 3 Within the area b shown.

[0105] Below Figure 3 The refrigerator shown in the example is combined with Figure 4 and Figure 5 , the embodiments of the present disclosure are described in detail. Figure 4 For the general Figure 3 A partial top view of the refrigerator in the cabinet 400, Figure 4 The refrigerator area shown in Figure 3 Area C shown in . Figure 5 for Figure 4 A local enlarged schematic diagram of point D in the middle.

[0106] refer to Figure 3 , Figure 4 and Figure 5 , the cabinet 400 may be provided with a storage chamber 410. The storage chamber 410 has two storage side walls 411 arranged opposite to each other. The cabinet 400 has a cabinet front wall 420 located at the front side. The cabinet front wall 420 intersects with the storage side wall 411 to form a cabinet side edge R. The box body 100 may be accommodated in the storage chamber 410. The box body 100 may include a box front wall 110, a box rear wall 120 and two box side walls 130. The box front wall 110 may be located at the front side of the refrigerator, and the box front wall 110 may be formed with a take-and-drop opening. Exemplarily, the box front wall 110 may be a side wall of the box housing located at the front side of the refrigerator. The side wall may be docked with the side wall adjacent to the take-and-drop opening in the box liner. The box rear wall 120 may be located at the rear side of the refrigerator, and is arranged opposite to the box front wall 110. The two box side walls 130 may be arranged opposite to each other, and are both connected to the box front wall 110 and the box rear wall 120. The distance between the box side wall 130 and the receiving side wall 411 may be within 5 mm. The hinge assembly 300 may be connected to the box front wall 110 and close to the box side wall 130 .

[0107] The door body 200 may include a door front wall 210, a door rear wall 220, two door side walls, a door top wall 250 and a door bottom wall. When the door body 200 is closed, the door front wall 210 and the door rear wall 220 are parallel to the box front wall 110, and the door front wall 210 is farther away from the box body 100 than the door rear wall 220. The two door side walls are arranged opposite to each other and are connected to the door front wall 210 and the door rear wall 220. The door top wall 250 is located above the door front wall 210, the door rear wall 220 and the two door side walls, and is connected to the door front wall 210, the door rear wall 220 and the two door side walls. The door bottom wall is located below the door front wall 210, the door rear wall 220 and the two door side walls, and is connected to the door front wall 210, the door rear wall 220 and the two door side walls. The side wall of the two door side walls close to the hinge assembly 300, that is, the side wall close to the cabinet 400 is the first door side wall 230, and the other door side wall is the second door side wall 240. The hinge assembly 300 can be connected to the door top wall 250 and is close to the first door side wall 230.

[0108] The door front wall 210 and the first door side wall 230 of the door body 200 intersect to form a first side edge J, and the first door side wall 230 and the door rear wall 220 intersect to form a second side edge K. When the door body 200 is closed, the first side edge J is located on the side of the second side edge K away from the box body 100.

[0109] It should be noted that when the door front wall 210 and the first door side wall 230 are both flat wall surfaces, the intersection line of the plane where the door front wall 210 is located and the plane where the first door side wall 230 is located is the theoretical first side edge J. A transition fillet is set at the intersection of the door front wall 210 and the first door side wall 230 to form a curved surface extending in the height direction of the door body 200. For ease of description, any straight line on the curved surface extending in the height direction of the door body 200 represents the first side edge J. Similarly, a transition fillet is set at the intersection of the door rear wall 220 and the first door side wall 230. The second side edge K can be represented by the intersection line of the planes where the door rear wall 220 and the first door side wall 230 are located, or by a straight line close to the intersection line and parallel to the intersection line.

[0110] The hinge assembly 300 may be connected to the door top wall 250 or the door bottom wall. For example, the door top wall 250 or the door bottom wall may be provided with a mounting groove 251, and the hinge assembly 300 may be installed in the mounting groove 251. Figure 4 and Figure 5As shown, taking the installation groove 251 provided on the door top wall 250 as an example, when the door body 200 is closed, the side of the installation groove 251 facing the box front wall 110 may be provided with a first opening 252. The side of the installation groove 251 facing the cabinet 400 may be provided with a second opening 253, and the second opening 253 is connected to the first opening 252. In other words, when the door body 200 is closed, the side of the installation groove 251 facing the box front wall 110 and the side facing the cabinet 400 are both open, and in the process of opening or closing the door body 200, the groove wall of the installation groove 251 can be prevented from interfering with the hinge assembly 300 and limiting the movement range of the door body 200.

[0111] The door rear wall 220 of the door body 200 may be provided with a door seal. When the door body 200 is closed, the door seal may surround the access opening and fit with the box front wall 110 of the box body 100, so that the door body 200 and the box body 100 can be sealed and connected, thereby preventing the cold in the storage room from overflowing. For example, the door seal may be a ring-shaped rubber strip. Figure 6 , Figure 7 , Figure 8 and Fig. 9 , the hinge assembly 300 of the embodiment of the present disclosure is described in detail. It should be noted that the door opening angle of the door body 200 refers to Figure 7 As shown, the angle α between the door front wall 210 and the box front wall 110 during the process of opening the door body 200 is referred to as the door opening angle α.

[0112] The hinge assembly 300 may include a mounting seat 310 , a first rod 320 , a second rod 330 , a third rod 340 , a fourth rod 350 , and a fifth rod 360 .

[0113] The mounting base 310 may be connected to the front wall 110 of the box body 100 .

[0114] The first rod 320 , the second rod 330 , the third rod 340 , the fourth rod 350 , and the fifth rod 360 each have a first end and a second end opposite to each other.

[0115] The first end of the first rod 320 can be rotatably connected to the mounting seat 310 via the first hinge shaft 371. The axis point of the first hinge shaft 371 is the axis point A, and the first rod 320 and the mounting seat 310 can rotate relative to each other around the axis point A.

[0116] The first end of the second rod 330 can be rotatably connected to the mounting base 310 via the second hinge shaft 372. The axis point of the second hinge shaft 372 is the axis point B, and the second rod 330 and the mounting base 310 can rotate relative to each other around the axis point B. Compared with the axis point A, the axis point B is closer to the box front wall 110 and closer to the center of the storage chamber.

[0117] The third rod 340, for example, the middle part thereof, can be rotatably connected to the second end of the first rod 320 through the third hinge shaft 373. The axis point of the third hinge shaft 373 is the axis point L, and the third rod 340 and the first rod 320 can rotate relative to each other around the axis point L. The first end of the third rod 340 can be rotatably connected to the second rod 330, for example, the middle part of the second rod 330, through the fourth hinge shaft 374. The axis point of the fourth hinge shaft 374 is the axis point M, and the third rod 340 and the second rod 330 can rotate relative to each other around the axis point M.

[0118] The first end of the fourth rod 350 can be rotatably connected to the second end of the second rod 330 via the fifth hinge shaft 375. The axis point of the fifth hinge shaft 375 is the axis point N, and the fourth rod 350 and the second rod 330 can rotate relative to each other around the axis point N.

[0119] The first end of the fifth rod 360 can be rotatably connected to the second end of the third rod 340 via the sixth hinge shaft 376. The axis point of the sixth hinge shaft 376 is the axis point P, and the fifth rod 360 and the third rod 340 can rotate relative to each other around the axis point P. The second end of the fifth rod 360 can be rotatably connected to the second end of the fourth rod 350 via the seventh hinge shaft 377. The axis point of the seventh hinge shaft 377 is the axis point Q. The axis point Q is farther from the first door side wall 230 than the axis point P. The fifth rod 360 can be connected to the door top wall 250 of the door body 200, for example, the fifth rod 360 can be installed in the installation groove 251 of the door top wall 250.

[0120] The axis point A of the first hinge axis 371, the axis point B of the second hinge axis 372, the axis point L of the third hinge axis 373, the axis point M of the fourth hinge axis 374, the axis point N of the fifth hinge axis 375, the axis point P of the sixth hinge axis 376, and the axis point Q of the seventh hinge axis 377 are parallel to each other. The mounting base 310, the first rod 320, the second rod 330, the third rod 340, the fourth rod 350, and the fifth rod 360 form a six-bar linkage.

[0121] like Figure 7 and Figure 8 As shown, when a pulling force f is applied to the door body 200, during the process of opening the door body 200 from the closed state, the fifth rod 360 drives the third rod 340 and the fourth rod 350, so that the third rod 340 rotates in the first direction relative to the fifth rod 360, and the fourth rod 350 rotates in the first direction relative to the fifth rod 360. For example, the first direction can be Figure 7 and Figure 8The third rod 340 drives the first rod 320 and the second rod 330, so that the first rod 320 rotates in the second direction relative to the mounting base 310, and the second rod 330 rotates in the second direction relative to the mounting base 310. The fourth rod 350 drives the second rod 330, so that the second rod 330 rotates in the second direction relative to the mounting base 310. The second direction is opposite to the first direction. For example, the second direction can be Figure 7 and Figure 8 The door opening angle α gradually increases until the hinge assembly 300 is in the unfolded state and the door body 200 is opened to the position shown in FIG. Fig. 9 The maximum door opening angle α shown max .

[0122] When a thrust is applied to the door body 200 and the door body 200 is closed, the fifth rod 360 drives the third rod 340 and the fourth rod 350, so that the third rod 340 rotates in the second direction relative to the fifth rod 360, and the fourth rod 350 rotates in the second direction relative to the fifth rod 360. The third rod 340 drives the first rod 320 and the second rod 330, so that the first rod 320 rotates in the first direction relative to the mounting seat 310, and the second rod 330 rotates in the first direction relative to the mounting seat 310. The fourth rod 350 drives the second rod 330, so that the second rod 330 rotates in the first direction relative to the mounting seat 310. The door opening angle α gradually decreases until the hinge assembly 300 is in a closed state and the door body 200 is closed.

[0123] It should be noted that the door opening angle α in the present disclosure can be obtained by actually measuring the equivalent door opening angle α. The equivalent door opening angle α may refer to the angle between the plane where the bottom surface of the mounting base 310 parallel to the refrigerator box front wall 110 is located and the connecting line PQ. In the embodiment of the present disclosure, since the plane where the bottom surface of the mounting base 310 is located is parallel to the box front wall 110, and the connecting line PQ is parallel to the door front wall 210, the door opening angle α is substantially equal to the equivalent door opening angle α.

[0124] Some embodiments of the present disclosure can solve any one of the following technical problems:

[0125] 1. When the hinge assembly in the home field is applied to the refrigerator, the maximum opening angle of the door body 200 is limited to only 90°~114°, and it cannot be further increased. The refrigerator of the disclosed embodiment can increase the maximum opening angle of the door body 200 so that the door body 200 moves more significantly toward the front and outside of the refrigerator relative to the cabinet 100, so that when the door body 200 is opened to the maximum opening angle, the obstruction of the door body 200 to the access opening can be reduced or eliminated. In particular, when a drawer is provided in the storage room, the interference between the drawer and the door body 200 can be prevented during the process of pushing and pulling the drawer after the door body 200 is opened.

[0126] 2. When the hinge assembly in the home field is applied to a refrigerator, when the door body 200 is at the maximum door opening angle, the portion of the door body 200 close to its second side edge K will block the access opening of the storage chamber, causing inconvenience in taking and placing items. In the refrigerator of the disclosed embodiment, during the process of opening the door body 200, the door body 200 can move to a greater extent toward the front and outside of the refrigerator relative to the cabinet 100. When the door body 200 is at the maximum door opening angle, the blocking of the access opening by the portion of the door body 200 close to the second side edge K can be reduced or eliminated, so as to facilitate users to take and place items. In particular, when a drawer is arranged in the storage chamber, in the process of pushing and pulling the drawer after opening the door body 200, interference between the drawer and the door body 200 can be prevented.

[0127] 3. When the hinge assembly in the home field is applied to a refrigerator, in the initial stage of opening the door body 200, that is, when the opening angle of the door body 200 is small during the process of opening the door body 200, the door body 200 moves relatively small relative to the cabinet 100 toward the front and inner side of the refrigerator, resulting in a relatively small safety distance for the first side edge J of the door body 200 to avoid collision with the cabinet 400. In the refrigerator of the disclosed embodiment, in the initial stage of opening the door, the door body 200 can move relatively large relative to the cabinet 100 toward the front and inner side of the refrigerator, thereby increasing the safety distance for preventing the first side edge J of the door body 200 from colliding with the cabinet 400.

[0128] Among them, any one of the technical disclosures in the present disclosure can solve one or more of the above-mentioned technical problems and achieve certain invention purposes to a certain extent; multiple technical disclosures can also be combined into an overall solution to solve one or more of the above-mentioned technical problems and achieve certain invention purposes; some of the technical disclosures can also be selected to be combined into an overall solution, while adopting existing technologies and deteriorated solutions, but the deterioration trend can be compensated by the means of the present technical disclosure, and the above-mentioned one or more technical problems can be solved to a certain extent as a whole and certain invention purposes can be achieved; each technical disclosure is combined into a complete technical solution, which constitutes an organic and inseparable overall solution, which solves technical problems as a whole and achieves certain invention purposes.

[0129] Any technical disclosure in the present disclosure, as well as the recombination of multiple technical disclosures, can form a complete technical solution, and can solve one or more of the above-mentioned technical problems and achieve the purpose of the invention. They all belong to the content of the present disclosure and belong to the content that is directly and unambiguously determined based on the content of the present disclosure.

[0130] The hinge assembly 300 in the embodiment of the present disclosure can increase the maximum door opening angle α of the door body 200. max .For example Fig. 9 As shown, in the embodiment of the present disclosure, the maximum opening angle α of the door body 200 max Theoretically, it can reach 129°~144°. Fig.10 In the related art, the maximum opening angle α of the door body 200 is max Compared with the related art, the refrigerator of the embodiment of the present disclosure can increase the maximum opening angle α of the door body 200 during the process of opening the door body. max , the door body 200 can move to a greater extent toward the front and outside of the refrigerator relative to the box body 100, thereby preventing the door body 200 from blocking the access opening of the storage chamber.

[0131] In some embodiments of the present disclosure, Figure 6 As shown, the mounting base 310 may include a first mounting plate 311 and two second mounting plates 312. The first mounting plate 311 may be parallel to the box front wall 110 and connected to the box front wall 110. Exemplarily, the first mounting plate 311 may be connected to the box front wall 110 by connecting bolts, rivets, etc.

[0132] The two second mounting plates 312 can be perpendicular to the first mounting plate 311 and respectively connected to the opposite sides of the first mounting plate 311. Such a configuration can improve the structural strength of the mounting base 310, thereby improving the structural strength of the hinge assembly 300, so that the hinge assembly 300 can support a heavier door body 200.

[0133] In addition, the two second mounting plates 312 and the first mounting plate 311 can also be enclosed to form a accommodating space. When the hinge assembly 300 is in a closed state, the accommodating space can accommodate at least a portion of the hinge assembly 300 to protect the hinge assembly 300, thereby preventing the rods from interfering with other components in the refrigerator.

[0134] The first hinge shaft 371 and the second hinge shaft 372 may be connected to the two second mounting plates 312. For example, the two second mounting plates 312 may be provided with a first connection hole and a second connection hole, the second connection hole being closer to the first mounting plate 311 and closer to the center of the storage chamber than the first connection hole.

[0135] Both ends of the first hinge shaft 371 are respectively inserted into the first connection holes of the two second mounting plates 312 .

[0136] Both ends of the second hinge shaft 372 are respectively inserted into the second connection holes of the two second mounting plates 312 .

[0137] The two mounting plates can support both ends of the first hinge shaft 371 and both ends of the second hinge shaft 372 , thereby improving the stability of the rotation of the first hinge shaft 371 and the second hinge shaft 372 , thereby improving the movement stability of the hinge assembly 300 and the door body 200 .

[0138] The following takes the case where the door body 200 is opened to 60° as an example to further describe the technical solution of the embodiment of the present disclosure in detail.

[0139] refer to Fig.11 and Fig.12 , Fig.11 This is a schematic diagram of a refrigerator door 200 in an embodiment of the present disclosure when opened to 60°. Fig.12 for Fig.11 Schematic diagram of the middle hinge assembly 300.

[0140] It should be noted that in Fig.12 In the schematic diagram of the hinge assembly 300 shown, the axis of each hinge axis is represented as a point. To facilitate the description of the embodiments of the present disclosure in conjunction with the drawings, the hinge axis and its axis point may be represented by a point corresponding to the axis of each hinge axis.

[0141] For example, point A can be used to represent the first hinge axis 371 and its axis point A, point B can be used to represent the second hinge axis 372 and its axis point B, point L can be used to represent the third hinge axis 373 and its axis point L, point M can be used to represent the fourth hinge axis 374 and its axis point M, point N can be used to represent the fifth hinge axis 375 and its axis point N, point P can be used to represent the sixth hinge axis 376 and its axis point P, and point Q can be used to represent the seventh hinge axis 377 and its axis point Q.

[0142] like Fig.12 As shown, AB, AL, BMN, PLM, NQ and PQ form a six-bar linkage.

[0143] Among them, PQ is fixedly connected to the door body 200, and point P and point Q are fixed relative to the door body 200. The motion trajectory of point P and point Q can be used to represent the motion trajectory of the door body 200, with point P as the main trajectory point and point Q as the auxiliary trajectory point.

[0144] The motion trajectory of the main trajectory point P and the auxiliary trajectory point Q is composed of a quadrilateral ABQP.

[0145] The lengths of AB and PQ are fixed values. During the process of opening the door body 200, the lengths of AP and BQ are variable values, and the lengths of AP and BQ increase with the increase of the door opening angle α, and the length change rate of AP is different from the length change rate of BQ.

[0146] In the process from closing the door body 200 to opening the door body 200 , the door body 200 can first move toward the front and inside of the refrigerator, and then move toward the front and outside of the refrigerator, thereby preventing the door body 200 from interfering with the cabinet 400 .

[0147] In other words, quadrilateral ABQP includes ΔABP and ΔBPQ.

[0148] ΔABP determines the motion trajectory of the main trajectory point P. In ΔABP, AP and BP increase as the opening angle α of the door body 200 increases.

[0149] ΔBPQ constitutes the motion trajectory of the auxiliary trajectory point Q. In ΔBPQ, BP and BQ increase as the door opening angle α of the door body 200 increases.

[0150] Generally speaking, the motion trajectory of the main trajectory point P and the auxiliary trajectory point Q is composed of six circular motions, thereby forming the motion trajectory of the door body 200 .

[0151] Specifically, during the process of opening the door body 200, point A is a fixed point. The motion trajectory of point L is a portion of the first circle C1, the first circle C1 has point A as the center and AL as the radius. The motion trajectory of the main trajectory point P is a portion of the second circle C2, the second circle C2 has point L as the center and PL as the radius. Point L always moves on the first circle C1, forming a dynamic center L.

[0152] In ΔPLA, according to the cosine theorem formula, the length of AP satisfies the following formula:

[0153] ; (1)

[0154] in, is ∠ALP, during the process of opening the door body 200 It can be less than 180°, so that AP increases as the opening angle α of the door body 200 increases.

[0155] In the process of opening the door body 200, point B is a fixed point. The motion trajectory of point M is a part of the third circle C3, the third circle C3 has point B as the center and BM as the radius. The motion trajectory of the main trajectory point P is a part of the fourth circle C4, the fourth circle C4 has point M as the center and PM as the radius. Point M always moves on the third circle C3, forming a dynamic center M.

[0156] In ΔPBM, according to the cosine theorem formula, the length of BP satisfies the following formula:

[0157] ; (2)

[0158] in, ∠BMP, in the process of opening the door body 200 It always increases. It can be less than 180°. Therefore, when it is less than 180°, BP increases as the opening angle α of the door body 200 increases.

[0159] In the process of opening the door body 200, point B is a fixed point. The motion trajectory of point N is a part of the fifth circle C5, the fifth circle C5 has point B as the center and BN as the radius. The motion trajectory of auxiliary trajectory point Q is a part of the sixth circle C6, the sixth circle C6 has point N as the center and QN as the radius. Point N always moves on the fifth circle C5, forming a dynamic circle center N.

[0160] In ΔQBN, according to the cosine theorem formula, the length of BQ satisfies the following formula:

[0161] ; (3)

[0162] in, ∠BNQ, in the process of opening the door body 200 It always increases. It can be less than 180°. Therefore, less than 180° makes BQ increase with the increase of the door opening angle α of the door body 200.

[0163] For a refrigerator with a hinge assembly in the home field in the related art, as the opening angle α of the door body 200 increases, will increase and exceed 180°. When it does not exceed 180°, BQ increases gradually with the increase of the door opening angle α. After exceeding 180°, BQ gradually decreases as the door opening angle α increases.

[0164] In the embodiments of the present disclosure, reference Fig.13 , the distance H between the axis point A of the first hinge axis 371 and the box front wall 110 1 Can be greater than or equal to 36mm.

[0165] When the hinge assembly 300 is in a closed state, the axis point A of the first hinge axis 371 is the axis point farthest from the box front wall 110 among the axis points of the hinge axes of the hinge assembly 300, and the distance between the axis point A and the box front wall 110 directly affects the thickness H of the hinge assembly 300. The thickness H of the hinge assembly 300 refers to the width of the hinge assembly 300 in a direction perpendicular to the box front wall 110 when the hinge assembly 300 is in a closed state.

[0166] For example Fig.13 As shown, when the door body 200 is closed, the hinge assembly 300 is in a closed state. The direction perpendicular to the box front wall 110 is direction y. The width H of the hinge assembly 300 in direction y is the thickness H of the hinge assembly 300, hereinafter referred to as the thickness H of the hinge assembly.

[0167] Set the distance H 1 The thickness H of the hinge assembly 300 is set to be greater than or equal to 36 mm, which is conducive to increasing the volume of each rod in the hinge assembly 300, thereby increasing the length of each rod, and further facilitating the adjustment of the movement trajectory of the main trajectory point P and the auxiliary trajectory line Q, thereby reducing the maximum opening angle α of the door body 200. max It is helpful to increase the cross-sectional area of ​​each rod, thereby increasing the structural strength of the hinge assembly 300, so that the hinge assembly 300 can be adapted to the door body 200 with a larger thickness, thereby increasing the applicable scope of the hinge assembly 300.

[0168] If the distance H 1 Less than 36mm, distance H 1 If the thickness H of the hinge assembly 300 is too small, the volume of each rod in the hinge assembly 300 is limited, which is not conducive to increasing the length of each rod, and thus is not conducive to adjusting the motion trajectory of the main trajectory point P and the auxiliary trajectory line Q. In order to increase the maximum opening angle α of the door body 200 max It is not conducive to increasing the cross-sectional area of ​​each rod, and thus is not conducive to increasing the structural strength of the hinge assembly 300, so that the hinge assembly 300 cannot be adapted to the door body 200 with a larger thickness, and the applicable scope of the hinge assembly 300 is reduced.

[0169] In some embodiments of the present disclosure, the distance H 1 This arrangement can prevent the thickness H of the hinge assembly 300 from being too large, thereby preventing the width of the mounting groove 251 on the door top wall 250 in the direction y from being too large, ensuring that there is a sufficiently large distance between the first groove side wall 254 opposite to the first opening 252 in the mounting groove 251 and the door front wall 210, so that the second heat insulation layer filled between the first groove side wall 254 and the door front wall 210 will not be too thin, thereby ensuring the thermal insulation performance of the door body 200.

[0170] If the distance H 1 Greater than 45mm, distance H 1If the thickness H of the hinge assembly 300 is too large, the width of the mounting groove 251 on the door top wall 250 will be increased, thereby reducing the distance between the groove side wall of the mounting groove 251 and the door front wall 210, making the second heat insulation layer filled between the groove side wall of the mounting groove 251 and the door front wall 210 too thin, thereby reducing the thermal insulation performance of the door body 200.

[0171] In some embodiments of the present disclosure, the distance H between the axis point B of the second hinge axis 372 and the box front wall 110 is 2 Such arrangement can ensure that there is a sufficient distance between the second hinge shaft 372 and the front wall 110, which is conducive to increasing the movement range of the door body 200 relative to the box body 100 toward the outside of the refrigerator during the process of opening the door body 200, thereby preventing the door body 200 from colliding with the cabinet 400.

[0172] If the distance H 2 Less than 15mm, distance H 2 If it is too small, the distance between the second hinge axis 372 and the front wall 110 of the box will be limited. During the process of opening the door body 200, it will not be conducive to increasing the movement range of the door body 200 relative to the box body 100 toward the outside of the refrigerator, thereby making it easy for the door body 200 to collide with the cabinet 400.

[0173] In some embodiments of the present disclosure, the distance H between the axis point B of the second hinge axis 372 and the box front wall 110 is 2 Can be less than or equal to 30mm.

[0174] The mounting base 310 is connected to the front wall 110 of the box by connecting bolts or rivets. The door body 200 is hinged to the mounting base 310 at the second hinge axis 372 through the fifth rod 360, the fourth rod 350 and the second rod 330. In the process of opening the door body 200, the heavier door body 200 applies a downward load moment to the connecting bolts or rivets through the unfolded fifth rod 360, the fourth rod 350, the second rod 330 and the mounting base 310. The arm of the load moment is the orthographic projection of the horizontal distance between the center of the door body 200 and the axis point B in the direction y, and the distance H between the axis point B and the front wall 110 2 sum.

[0175] Distance H 2 The larger the distance H, the longer the lever arm, and the greater the load moment borne by the connecting bolt or rivet. 2 By setting it to be less than or equal to 30 mm, it is possible to prevent the connecting bolts or rivets from being subjected to excessive load torque, thereby ensuring the connection reliability between the mounting seat 310 and the box front wall 110 .

[0176] If the distance H 2 Greater than 30mm, distance H2 If the size is too large, the connecting bolts or rivets will be subjected to excessive load torque, making it easy for the mounting base 310 to separate from the box front wall 110 , thereby reducing the connection reliability between the hinge assembly 300 and the box body 100 .

[0177] In some examples of the present disclosure, reference is made to Fig.13 and Fig.14 , the angle between the line between the axis point A and the axis point B and the box side wall 130, such as Fig.13 and 14 The first angle θ shown in can be greater than the first angle. The first angle can be any value between 25° and 30°. For example, the first angle can be 25°, 26°, 27°, 28°, 29° or 30°.

[0178] That is, the first angle θ may be greater than 25°. Alternatively, the first angle θ may be greater than 26°; the first angle θ may be greater than 27°; the first angle θ may be greater than 28°; the first angle θ may be greater than 29°; the first angle θ may be greater than 30°.

[0179] In the related art, reference Fig.15 and Fig.16 The hinge assembly 300 is usually used in a storage cabinet in the home field. The angle between the line between the axis point A and the axis point B and the box side wall 130 is as follows: Fig.16 The first angle θ shown is relatively small, typically 8° to 10°.

[0180] A smaller first angle θ can reduce the width of point A and point B in the horizontal direction parallel to the plane where the access port is located, that is, Fig.15 and Fig.16 The width H between point A and point B in the horizontal direction x is shown 3 , so as to reduce the overall width of the hinge assembly 300 in the unfolded state in the horizontal direction x as much as possible, so that when the door body 200 is opened to the maximum opening angle α max When doing so, the access opening of the locker is prevented from being blocked by the hinge assembly 300 as much as possible, so as to facilitate users to take and put items.

[0181] However, the smaller first angle θ makes the maximum opening angle α of the door body 200 max is limited and cannot be increased further. Fig.16 As shown, the track line p is the track line of the main track point P, and the track line q is the track line of the auxiliary track point Q. The smaller first angle θ is equivalent to making the track line p and the track line q rotate clockwise around the point A, so that the end points P1 and Q1 of the track line p and the track line q move toward the center of the locker, thereby reducing the maximum opening angle α of the door body 200. max In the related art, the maximum door opening angle αmax Usually 114°. However, in the home field, the size of the storage cabinet is usually large, and the thickness of the door body 200 is relatively thin. max It is only 114°, which will not affect the user's taking and placing of items and can still meet the user's usage requirements.

[0182] However, for refrigerators in the field of household appliances, the storage space in the box 100 is limited, and the thickness of the door 200 is relatively large, usually 50 mm to 60 mm. When the door 200 is opened, if the maximum opening angle α of the door 200 is max The door body 200 with a relatively small size and large thickness will block the access opening, making it inconvenient for users to access and place items, and making it inconvenient for users to observe the items in the storage room.

[0183] In some embodiments of the refrigerator disclosed herein, the first angle θ is increased by setting the first angle θ to be greater than the first angle. Fig.14 As shown, increasing the first angle θ is equivalent to making the track line p of the main track point P and the track line q of the auxiliary track point Q rotate counterclockwise around point A, so that the end points P1 and Q1 of the track line p and the track line q move to the outside of the refrigerator, thereby increasing the maximum opening angle α of the door body 200. max This is helpful to reduce or eliminate the obstruction of the door body 200 to the access opening when the door body 200 is opened, making it easier for users to access and place items, and easier for users to observe the status of items in the storage room.

[0184] In addition, reference Fig.17 , Fig.17 The door body 200 is opened to the maximum door opening angle α in the embodiment of the present disclosure. max Schematic diagram of hinge assembly 300.

[0185] When the door 200 is opened to the maximum angle α max When the door 200 is opened to the maximum opening angle α, the four sides AB, BP, AQ and PQ of the quadrilateral ABQP are almost located on the same straight line. max When , the angle between PQ and the box side wall 130 is close to the first angle θ between AB and the box side wall 130. The larger the first angle θ between AB and the box side wall 130, the larger the angle between PQ and the box side wall 130, and the larger the angle between PQ and the box front wall 110, that is, the maximum opening angle α of the door body 200 max In other words, the first angle θ between AB and the box side wall 130 and the maximum opening angle α of the door body 200 max There is a positive correlation.

[0186] After a lot of experimental simulations and research, the inventor found that the theoretically designed maximum door opening angle α max, so that the door body 200 needs to be opened to at least 129°, so that the door body 200 can be opened to the maximum opening angle α max When the door body 200 is opened, the portion close to the second side edge K thereof will not substantially block the loading and unloading opening.

[0187] It should be noted that the theoretically designed maximum door opening angle α max It means that the comparison between the present disclosure and the prior art is made from a theoretical design perspective, considering each rod and hinge axis as a theoretical line and point.

[0188] In the actual design of the embodiment of the present disclosure, it is necessary to consider the design avoidance for the width of the rod and the diameter of the hinge shaft to reserve space for the rod and the hinge shaft to avoid interference between the hinge point and the rod. Therefore, the maximum door opening angle α in the actual product design max Will be smaller than the theoretically designed maximum door opening angle α max .

[0189] For example, when the first angle θ is set to be greater than the first angle, and the first angle is greater than or equal to 25°, the first angle θ can be increased by at least 15°, and the maximum door opening angle α can be max Increase by more than 15°, that is to say, theoretically the maximum door opening angle α max Increased from 114° to about 129°, thus meeting the requirements of the maximum door opening angle.

[0190] For another example, when the first angle θ is set to be greater than the first angle, and the first angle is greater than or equal to 27°, the first angle θ can be increased by at least 17°, and the maximum door opening angle α can be increased by 17°. max Increase by more than 17°, that is to say, theoretically the maximum door opening angle α max It increases from 114° to about 131°, thus better meeting the requirements of the maximum door opening angle.

[0191] For another example, when the first angle θ is set to be greater than the first angle, and the first angle is greater than or equal to 30°, the first angle θ can be increased by at least 20°, and the maximum door opening angle α can be increased to max Increase by more than 20°, that is to say, theoretically the maximum door opening angle α max Increased from 114° to about 134°, so as to better meet the requirements of maximum door opening angle.

[0192] If the first angle θ is less than or equal to the first angle, the first angle θ is too small, which will result in the maximum door opening angle α max The increase is small. When the door is opened to the maximum opening angle α maxWhen the door 200 is closed, the portion of the door body 200 close to the second side edge K will still block the access opening, making it inconvenient for the user to take and place items, and making it inconvenient for the user to observe the items in the storage room.

[0193] In some embodiments of the present disclosure, the first angle θ may be smaller than the second angle. The second angle may be any value between 36° and 40°. For example, the second angle may be 36°, 37°, 38°, 39° or 40°.

[0194] That is, the first angle θ may be less than 36°. Alternatively, the first angle θ may be less than 37°; the first angle θ may be less than 38°; the first angle θ may be less than 39°; the first angle θ may be less than 40°.

[0195] For another example, when the first angle θ is set to be smaller than the second angle and the second angle is equal to 36°, the first angle θ can be increased by 26°, and the maximum door opening angle α can be increased by 26°. max Increase by more than 26°, that is to say, theoretically the maximum door opening angle α max It increases from 114° to about 140°, thus meeting the requirement of maximum door opening angle.

[0196] For another example, when the first angle θ is set to be smaller than the second angle and the second angle is equal to 38°, the first angle θ can be increased by at least 28°, and the maximum door opening angle α can be increased by 28°. max Increase by more than 28°, that is to say, theoretically the maximum door opening angle α max It increases from 114° to about 142°, thus meeting the requirements of a larger maximum door opening angle.

[0197] Furthermore, when the first angle θ is set to be smaller than the first angle and the second angle is equal to 40°, the first angle θ can be increased by at least 30°, and the maximum door opening angle α can be increased to max Increase by more than 30°, that is to say, theoretically the maximum door opening angle α max It increases from 114° to about 144°, thus meeting the requirements of a larger maximum door opening angle.

[0198] If the first angle θ exceeds the second angle, the first angle θ is too large. For example, if the first angle θ is 45°, the first angle θ can be increased by 35° to make the maximum door opening angle α max Increase by more than 35°, that is to say, theoretically the maximum door opening angle α max From 113° to about 148°, so that the maximum door opening angle α max Too large. Maximum door opening angle α maxWhen the door body 200 is opened to the maximum opening angle α, the door body will move toward the box body as a whole. max When the first angle θ exceeds the second angle, the first side edge J of the door body 200 is likely to collide with the cabinet front wall 420 of the cabinet 400. Fig.13 As shown, it is equivalent to that when the mounting base is fixed, the first rod 320, the second rod 330, the third rod 340, the fourth rod 350 and the fifth rod 360 of the hinge assembly 300 rotate counterclockwise around the axis point A, and the counterclockwise rotation angle is large, thereby increasing the width of the hinge assembly 300 in the direction y, that is, increasing the thickness H of the hinge assembly 300, which is not conducive to the overall miniaturization of the hinge assembly 300.

[0199] Therefore, the first angle θ is set to be smaller than the second angle. In the later stage of the door opening process, that is, when the door body is opened to a large angle and the maximum door opening angle α max When the first side edge J of the door body 200 is spaced from the front wall 420 of the cabinet 400 , a sufficiently large safety distance can be reserved between the first side edge J of the door body 200 and the front wall 420 of the cabinet 400 , thereby preventing the first side edge J of the door body 200 from colliding with the front wall 420 of the cabinet 400 .

[0200] It should be noted that, in the specific practical application process, on the basis of increasing the first angle θ, it can be combined with at least one other technical disclosure in the embodiment of the present disclosure to re-combine to form a complete technical solution, and through the joint action of multiple technical means, the portion of the door body 200 close to its second side edge K can be reduced or eliminated as much as possible to block the access port. At the same time, the reliability and stability of the hinge assembly 300 and the refrigerator can also be considered. For example, in order to make the hinge assembly 300 have a sufficiently large structural strength to support the heavier door body 200, each rod or each hinge shaft in the hinge assembly 300 needs to have a larger cross-sectional area or volume, etc. In the process of opening the door body 200, each rod and / or each hinge shaft will contact in advance to produce a limiting effect, thereby limiting the door opening angle α of the door body 200. Therefore, in the specific practical application, the door opening angle α of the door body 200 does not need to be opened to 129°.

[0201] In some embodiments of the present disclosure, as shown in the attached Figure 8 As shown, when the door 200 is opened to 115°, the line between the axis point B of the second hinge axis 372 and the axis point N of the fifth hinge axis 375, ie, BN, and the box front wall 110 may have a second angle τ. The second angle τ may be greater than or equal to 90°.

[0202] In the process of opening the door body 200, the second rod 330 can be considered as the component of the hinge assembly 300 that blocks the largest area of ​​the access opening. The second hinge shaft 372 and the fifth hinge shaft 375 are both connected to the second rod 330. To a certain extent, the blocking area of ​​the access opening by the door body 200 and the hinge assembly 300 can be characterized by the connecting line between the axis point B of the second hinge shaft 372 and the axis point N of the fifth hinge shaft 375, that is, the second angle τ between BN and the box front wall 110. The larger the second angle τ, the smaller the blocking area of ​​the access opening by the door body 200 and the hinge assembly 300.

[0203] In the embodiment of the present disclosure, by setting the second angle τ when the door body 200 is opened to 115° to be greater than or equal to 90°, the door body 200 and the hinge assembly 300 can have a smaller shielding area for the access opening, or will not shield the access opening when the door body 200 is opened to 115°. At the same time, sufficient space can be reserved for each rod and each hinge shaft in the hinge assembly 300, which is conducive to increasing the cross-sectional area or volume of each rod and each hinge shaft, thereby facilitating the reliability and stability of the hinge assembly 300 and the refrigerator.

[0204] If the second angle τ is set to be less than 90°, although more space can be reserved for each rod and each hinge axis in the hinge assembly 300 to further improve the reliability and stability of the hinge assembly 300 and the refrigerator, if the second angle τ is too small, the door body 200 and the hinge assembly 300 will block too large an area of ​​the access opening, making it inconvenient for users to access items and observe the items in the storage room.

[0205] In some embodiments of the present disclosure, Figure 8 As shown, when the door 200 is opened to 115°, the line between the axis point B of the second hinge axis 372 and the axis point M of the fourth hinge axis 374, namely BM, and the box front wall 110 may have a third angle μ. The third angle μ may be greater than or equal to 85°.

[0206] In the process of opening the door body 200, the second rod 330 can be considered as the component of the hinge assembly 300 that blocks the largest area of ​​the access opening. The second hinge shaft 372 and the fourth hinge shaft 374 are both connected to the second rod 330. To a certain extent, the blocking area of ​​the access opening by the door body 200 and the hinge assembly 300 can be characterized by the third angle μ between the connecting line between the axis point B of the second hinge shaft 372 and the axis point M of the fourth hinge shaft 374, that is, BM and the box front wall 110. The larger the third angle μ, the smaller the blocking area of ​​the access opening by the door body 200 and the hinge assembly 300.

[0207] In the embodiment of the present disclosure, by setting the third angle μ when the door body 200 is opened to 115° to be greater than or equal to 85°, the door body 200 and the hinge assembly 300 can have a smaller shielding area for the access opening, or will not shield the access opening when the door body 200 is opened to 115°. At the same time, sufficient space can be reserved for each rod and each hinge shaft in the hinge assembly 300, which is conducive to increasing the cross-sectional area or volume of each rod and each hinge shaft, thereby facilitating the reliability and stability of the hinge assembly 300 and the refrigerator.

[0208] If the third angle μ is set to be less than 85°, a larger space can be reserved for each rod and each hinge axis in the hinge assembly 300 to further improve the reliability and stability of the hinge assembly 300 and the refrigerator. However, if the third angle μ is too small, the door body 200 and the hinge assembly 300 will block too large an area of ​​the access opening, making it inconvenient for users to access items and observe the items in the storage room.

[0209] In some embodiments of the present disclosure, when the door body 200 is opened to 115°, the third angle μ may be less than or equal to 90°. If the third angle μ is greater than 90°, the distance between the second rod 330 and the cabinet side edge R of the cabinet 400 will be too close, so that the first rod 320, which is closer to the cabinet side edge R than the second rod 330, collides with the cabinet side edge R. By setting the third angle μ to be less than or equal to 90°, the embodiment of the present disclosure can prevent the first rod 320 from colliding with the cabinet side edge R due to the distance between the second rod 330 and the cabinet side edge R of the cabinet 400 being too close during the process of opening the door body 200.

[0210] The aforementioned door opening angle of 115° refers to the case where each rod and hinge shaft is considered as a theoretical line and point, and the theoretical design angle is considered as a reference in the present disclosure. In the actual design of the embodiment of the present disclosure, since it is necessary to consider the design avoidance for the strength, width and hinge shaft diameter of the rod, space is reserved for the rod and the hinge shaft to limit the actual maximum door opening angle, so that the actual maximum door opening angle may be smaller than the theoretically designed door opening angle of 115°, but it will not affect the theoretically designed door opening angle.

[0211] In the embodiments of the present disclosure, Fig.13 and Fig.14 As shown, when the door body 200 is closed, the door front wall 210 of the door body 200 intersects with the first door side wall 230 to form a first reference point E. The distance between the first reference point E and the axis point P, that is, EP, may be greater than or equal to 20 mm. EP may be less than or equal to 60 mm.

[0212] In some embodiments of the present disclosure, reference Fig.14Since point P and point Q are both arranged on the fifth rod 360, the relative position between point P and point Q is fixed, and point P and point Q have similar motion trajectories. In the process of opening the door body 200, point P and point Q having similar motion trajectories can make the door body as a whole move toward the front and inner side of the refrigerator relative to the cabinet. When the door body is opened to a certain door opening angle α, the door body 200 moves toward the front and outer side of the refrigerator relative to the cabinet 100. The door body 200 continues to open, and the door body 200 moves toward the outer side and rear side of the refrigerator relative to the cabinet 100.

[0213] And refer to Fig.40 , the first side edge J of the door body 200 is a fixed point on the door body 200, and its relative position with point P and point Q is fixed. Therefore, the first side edge J also has a motion trajectory similar to that of point P and point Q. The motion trajectory of the first side edge J is as follows: Fig.40 The motion trajectory shown in j.

[0214] The relative position between the first reference point E and the cabinet side edge R is fixed, so the first reference point E can be used to represent the position of the cabinet side edge R. The relative position between the main track point P and the first side edge J of the door body 200 is fixed, so the main track point P can be used to represent the position of the first side edge J of the door body 200 to a certain extent.

[0215] The distance between the first reference point E and the axis point P, i.e., EP, may be greater than or equal to 20 mm. EP may be less than or equal to 60 mm. In the process of opening the door body 200, EP within this numerical range can ensure a sufficiently large safety distance between the first side edge J of the door body 200 and the cabinet side edge R, thereby preventing the door body 200 from colliding with the cabinet 400.

[0216] If EP is less than 20 mm, EP is too small. During the process of automatically opening the door body 200, the distance between the first side edge J of the door body 200 and the cabinet side edge R is too small, and the door body 200 is easy to collide with the cabinet 400. If EP is greater than 60 mm, EP is too large. During the process of automatically opening the door body 200, the door body 200 requires a large opening space, which increases the working space required for normal use of the refrigerator, thereby reducing the applicable range of the refrigerator.

[0217] The variation trend of EP defines the motion trajectory of the main trajectory point P. In the embodiment of the present disclosure, the motion trajectory of the main trajectory point P can be adjusted by adjusting the variation trend of EP, thereby adjusting the motion trajectory of the door body 200 .

[0218] Exemplarily, the process of opening the door body 200 may include a first door opening stage and a second door opening stage.

[0219] The door opening angle α does not reach the first preset door opening angle α 1When α∈[0°, α 1 ) is the first door opening stage.

[0220] The door opening angle α exceeds the first preset door opening angle α 1 , the second preset door opening angle α is not reached 2 When α∈[α 1 , α 2 ), it is the second door opening stage. Among them, α 2 Greater than the first preset door opening angle α 1 .

[0221] The first preset door opening angle α 1 It can be any value between 20° and 30°. The second preset door opening angle α 2 Can be 95°~α max Any value between .

[0222] For example, the first preset door opening angle α 1 It can be 20° or 30°. The second preset door opening angle α 2 Can be 95°, 100°, or 110° or the maximum door opening angle α max .

[0223] In the first door opening stage, the door body 200 can first move slightly toward the front and inside of the refrigerator relative to the box body 100, so that in the initial stage of opening the door body 200, the part of the door body 200 close to its first side edge J will not collide with the accommodating side wall 411 and the cabinet side edge R of the cabinet 400.

[0224] In the second door opening stage, the door body 200 can move significantly toward the front and outside of the refrigerator relative to the cabinet body 100, so that in the later stage of opening the door body 200, the part of the door body 200 close to its first side edge J will not collide with the cabinet side edge R of the cabinet 400 and the cabinet front wall 420.

[0225] In some embodiments of the present disclosure, Fig.18 As shown, in the first door opening stage and the second door opening stage, as the door opening angle α increases, the distance between the first reference point E and the axis point P, that is, EP, can gradually increase.

[0226] EP gradually increases. In the first door opening stage, the door body 200 can move more significantly and quickly toward the front and inner side of the refrigerator relative to the cabinet 100. At the same time, the first side edge J of the door body 200 can move toward the inner side and front side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 will not exceed the side wall 130 of the cabinet 100, and at the same time, the first side edge J can exceed the cabinet front wall 420 more, thereby reducing or eliminating the possibility of the first side edge J colliding with the cabinet. In the second door opening stage, the door body 200 can move more significantly toward the front and outer side of the refrigerator. At the same time, the first side edge J of the door body 200 can move more significantly toward the front and outer side of the refrigerator relative to the cabinet 100.

[0227] In other embodiments of the present disclosure, Fig.19 As shown in FIG. 1 , in the first door opening stage, EP may first increase and then decrease. For example, the decrease amplitude Δep of EP is 1 It may not exceed 2 mm. In the second door opening stage, EP may be gradually increased.

[0228] Compared with the above embodiment, in the first door opening stage, when the door opening angle α is small, EP increases, the door body 200 can move relatively more significantly toward the front and inner side of the refrigerator, and at the same time, the first side edge J of the door body 200 can move relatively more significantly toward the inner side and front side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 does not exceed the box side wall 130 of the cabinet 100. In the first door opening stage, when the door opening angle α is large, the first side edge J of the door body 200 has accumulated a margin of movement inward and forward during the small-angle door opening process. At this time, that is, in the relatively large door opening angle range in the first door opening stage, EP decreases slightly, and there is a possibility that the first side edge J of the door body 200 slightly exceeds the box side wall 130 of the cabinet 100. However, in this larger door opening angle range, the door body 200 has moved relatively significantly toward the front side of the refrigerator relative to the cabinet 100, so that the first side edge J has exceeded the cabinet front wall 420, so that there is a sufficiently large safety distance between the first side edge J and the cabinet side edge R, thereby reducing or eliminating the possibility of the first side edge J colliding with the cabinet. Although the movement amount of the door body 200 toward the inside of the refrigerator is relatively small in the first door opening stage, the purpose of the invention can still be achieved. In the second door opening stage, the door body 200 can move relatively more significantly toward the front and outside of the refrigerator, and at the same time, the first side edge J of the door body 200 can move relatively more significantly toward the front and outside of the refrigerator relative to the cabinet 100.

[0229] In other embodiments of the present disclosure. Fig. 20 As shown, in the first door opening stage, EP can be maintained at the first value ep 1 unchanged, then decreases, and then gradually increases. For example, the decrease in EP Δep 2It can be no more than 2mm. Alternatively, the reduction in EP is Δep 2 Can be greater than the first value ep 1 5% and less than the first value ep 1 In the second door opening stage, EP can be gradually increased.

[0230] Compared with the embodiment in which EP gradually increases, in the first door opening stage, when the door opening angle α is small, EP can remain unchanged first, and the door body 200 can move relatively greatly and quickly toward the front and inner side of the refrigerator, and at the same time, the first side edge J of the door body 200 can move toward the inner side and front side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 does not exceed the box side wall 130 of the cabinet 100. In the first door opening stage, when the door opening angle α is large, that is, within the larger door opening angle range of the first door opening stage, EP decreases slightly, and there is a possibility that the first side edge J of the door body 200 slightly exceeds the box side wall 130 of the cabinet 100. However, in the first door opening stage, within the larger door opening angle range, the door body 200 has moved relatively significantly toward the front side of the refrigerator relative to the cabinet 100, so that the first side edge J has largely exceeded the cabinet front wall 420, thereby allowing a sufficiently large safety distance between the first side edge J and the cabinet side edge R, thereby reducing or eliminating the possibility of the first side edge J colliding with the cabinet. Although the movement amount of the door body 200 toward the inside of the refrigerator is relatively small in the first door opening stage, the purpose of the invention can still be achieved. In the second door opening stage, the door body 200 can move relatively more significantly toward the front and outside of the refrigerator, and at the same time, the first side edge J of the door body 200 can move relatively more significantly toward the front and outside of the refrigerator relative to the cabinet 100.

[0231] In other embodiments of the present disclosure, Fig.21 As shown, in the first door opening stage, EP can be maintained at the second value ep 2 In the second door opening stage, EP can be gradually increased.

[0232] Compared with the embodiment in which EP gradually increases, in the first door opening stage, when the door opening angle α is small, EP remains unchanged, the door body 200 can move relatively greatly and quickly toward the front and inner side of the refrigerator, and at the same time, the first side edge J of the door body 200 can move toward the inner side and front side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 does not exceed the box side wall 130 of the cabinet 100. In the first door opening stage, when the door opening angle α is large, that is, in the larger door opening angle range of the first door opening stage, EP remains unchanged, when the first side edge J of the door body 200 is substantially flush with the box side wall 130 of the cabinet 100, that is, in the larger door opening angle range, the door body 200 has moved relatively greatly toward the front side of the refrigerator relative to the cabinet 100, so that the first side edge J has exceeded the cabinet front wall 420, so that there is a sufficient safety distance between the first side edge J of the door body 200 and the cabinet side edge R, thereby reducing or eliminating the possibility of collision between the first side edge J and the cabinet 400. Although the movement of the door body 200 toward the inside of the refrigerator is relatively small in the first door opening stage, the purpose of the invention can still be achieved. In the second door opening stage, the door body 200 can move toward the front and outside of the refrigerator to a greater extent, and at the same time, the first side edge J of the door body 200 can move toward the front and outside of the refrigerator to a greater extent relative to the cabinet 100.

[0233] In other embodiments of the present disclosure, Fig. 22 As shown, in the first door opening stage, EP can decrease or increase multiple times, that is, EP can fluctuate. For example, the fluctuation amplitude Δep of EP is 3 It can be less than 2 mm. In the second door opening stage, EP can be gradually increased.

[0234] Compared with the embodiment in which EP gradually increases, in the first door opening stage, within a small angle range, the door body 200 can move relatively greatly and quickly toward the front and inner side of the refrigerator. At the same time, the first side edge J of the door body 200 moves toward the front and inner side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 does not exceed the side wall 130 of the cabinet 100. In the first door opening stage, within a small angle range, the first side edge J of the door body 200 moves inward. Although EP decreases slightly for many times, the first side edge J of the door body 200 slightly exceeds the side wall of the cabinet. However, in the first door opening stage, the door body 200 always moves toward the front side of the refrigerator relative to the cabinet 100, so that the first side edge J has exceeded the cabinet front wall 420, so that there is a sufficient safety distance between the first side edge J of the door body 200 and the cabinet side edge R, thereby reducing or eliminating the possibility of collision between the first side edge J and the cabinet 400. Although the movement of the door body 200 toward the inside of the refrigerator is relatively small in the first door opening stage, the purpose of the invention can still be achieved. In the second door opening stage, the door body 200 can move toward the front and outside of the refrigerator to a greater extent, and at the same time, the first side edge J of the door body 200 can move toward the front and outside of the refrigerator to a greater extent relative to the cabinet 100.

[0235] In the embodiments of the present disclosure, Fig.13 As shown, when the door body 200 is closed, the axis point A is projected onto the door front wall 210 along the direction y, and intersects with the door front wall 210 to form a second reference point F. Fig.23 , which is a schematic diagram of the hinge assembly 300 when the door body 200 is closed, and a schematic diagram of the change trend of FP.

[0236] The distance between the second reference point F and the axis point P, FP, may be greater than or equal to 14 mm. FP may be less than or equal to 54 mm.

[0237] The relative position between the second reference point F and the cabinet side edge R is fixed, so the second reference point F can be used to represent the position of the cabinet side edge R. The relative position between the main track point P and the first side edge J of the door body 200 is fixed, so the main track point P can be used to represent the position of the first side edge J of the door body 200 to a certain extent.

[0238] The distance between the second reference point F and the axis point P, i.e., FP, may be greater than or equal to 14 mm. FP may be less than or equal to 54 mm. In the process of opening the door body 200, FP within this numerical range can ensure a sufficiently large safety distance between the first side edge J of the door body 200 and the cabinet side edge R, thereby preventing the door body 200 from colliding with the cabinet 400.

[0239] If FP is less than 14 mm, FP is too small, and during the process of automatically opening the door body 200, the distance between the first side edge J of the door body 200 and the cabinet side edge R is too small, and the door body 200 is easy to collide with the cabinet 400. If FP is greater than 54 mm, FP is too large, and during the process of automatically opening the door body 200, the door body 200 requires a large opening space, which increases the working space required for normal use of the refrigerator, thereby reducing the applicable range of the refrigerator.

[0240] The changing trend of FP defines the motion trajectory of the main trajectory point P. In the embodiment of the present disclosure, the motion trajectory of the main trajectory point P can be adjusted by adjusting the changing trend of FP, thereby adjusting the motion trajectory of the door body 200. In the first door opening stage, the door body 200 can first move slightly toward the front and inner side of the refrigerator relative to the cabinet 100, so that in the early stage of opening the door body 200, the part of the door body 200 close to its first side edge J will not collide with the containing side wall 411 and the cabinet side edge R of the cabinet 400. In the second door opening stage, the door body 200 can move significantly toward the front and outer side of the refrigerator relative to the cabinet 100, so that in the later stage of opening the door body 200, the part of the door body 200 close to its first side edge J will not collide with the cabinet side edge R and the cabinet front wall 420 of the cabinet 400.

[0241] In some embodiments of the present disclosure, Fig.24 As shown, in the first door opening stage and the second door opening stage, as the door opening angle α increases, the distance between the second reference point F and the axis point P, that is, FP, can gradually increase.

[0242] FP gradually increases. In the first door opening stage, the door body 200 can move more significantly and quickly toward the front and inner side of the refrigerator relative to the cabinet 100. At the same time, the first side edge J of the door body 200 can move toward the inner side and front side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 will not exceed the side wall 130 of the cabinet 100, and at the same time, the first side edge J can exceed the cabinet front wall 420 more, thereby reducing or eliminating the possibility of the first side edge J colliding with the cabinet. In the second door opening stage, the door body 200 can move more significantly toward the front and outer side of the refrigerator. At the same time, the first side edge J of the door body 200 can move more significantly toward the front and outer side of the refrigerator relative to the cabinet 100.

[0243] In other embodiments of the present disclosure, Fig.25 As shown in FIG. 1 , in the first door opening stage, FP may first increase and then decrease. For example, the decrease amplitude Δfp of FP is 1 It may not exceed 2 mm. In the second door opening stage, FP may be gradually increased.

[0244] Compared with the above embodiment, in the first door opening stage, when the door opening angle α is small, FP increases, the door body 200 can move relatively greatly toward the front and inner side of the refrigerator, and at the same time, the first side edge J of the door body 200 can move relatively toward the inner side and front side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 does not exceed the box side wall 130 of the cabinet 100. In the first door opening stage, when the door opening angle α is large, the first side edge J of the door body 200 has accumulated a margin of movement inward and forward during the small-angle door opening process. At this time, that is, in the relatively large door opening angle range in the first door opening stage, FP decreases slightly, and there is a possibility that the first side edge J of the door body 200 slightly exceeds the box side wall 130 of the cabinet 100. However, in this larger door opening angle range, the door body 200 has moved relatively significantly toward the front side of the refrigerator relative to the cabinet 100, so that the first side edge J has exceeded the cabinet front wall 420, so that there is a sufficiently large safety distance between the first side edge J and the cabinet side edge R, thereby reducing or eliminating the possibility of the first side edge J colliding with the cabinet. Although the movement amount of the door body 200 toward the inside of the refrigerator is relatively small in the first door opening stage, the purpose of the invention can still be achieved. In the second door opening stage, the door body 200 can move relatively more significantly toward the front and outside of the refrigerator, and at the same time, the first side edge J of the door body 200 can move relatively more significantly toward the front and outside of the refrigerator relative to the cabinet 100.

[0245] In other embodiments of the present disclosure. Fig.26 As shown, in the first door opening stage, FP can be maintained at the third value fp 1 unchanged, then decreases, and then gradually increases. For example, the reduction amplitude of FP Δfp 2 It can be no more than 2mm. Alternatively, the reduction of FP is Δfp 2 Can be greater than the third value fp 1 5% and less than the third value fp 1 In the second door opening stage, FP can be gradually increased.

[0246] Compared with the embodiment in which FP gradually increases, in the first door opening stage, when the door opening angle α is small, FP can remain unchanged first, and the door body 200 can move relatively greatly and quickly toward the front and inner side of the refrigerator. At the same time, the first side edge J of the door body 200 can move toward the inner side and front side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 does not exceed the box side wall 130 of the cabinet 100. In the first door opening stage, when the door opening angle α is large, that is, within the larger door opening angle range of the first door opening stage, FP decreases slightly, and there is a possibility that the first side edge J of the door body 200 slightly exceeds the box side wall 130 of the cabinet 100. However, in the first door opening stage, within the larger door opening angle range, the door body 200 has moved relatively significantly toward the front side of the refrigerator relative to the cabinet 100, so that the first side edge J has largely exceeded the cabinet front wall 420, thereby allowing a sufficiently large safety distance between the first side edge J and the cabinet side edge R, thereby reducing or eliminating the possibility of the first side edge J colliding with the cabinet. Although the movement amount of the door body 200 toward the inside of the refrigerator is relatively small in the first door opening stage, the purpose of the invention can still be achieved. In the second door opening stage, the door body 200 can move relatively more significantly toward the front and outside of the refrigerator, and at the same time, the first side edge J of the door body 200 can move relatively more significantly toward the front and outside of the refrigerator relative to the cabinet 100.

[0247] In other embodiments of the present disclosure, Fig. 27 As shown, in the first door opening stage, FP can be maintained at the fourth value fp 2 In the second door opening stage, FP can be gradually increased.

[0248] Compared with the embodiment in which FP gradually increases, in the first door opening stage, when the door opening angle α is small, FP remains unchanged, the door body 200 can move relatively greatly and quickly toward the front and inner side of the refrigerator, and at the same time, the first side edge J of the door body 200 can move toward the inner side and front side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 does not exceed the side wall 130 of the cabinet 100. In the first door opening stage, when the door opening angle α is large, that is, in the larger door opening angle range of the first door opening stage, FP remains unchanged, when the first side edge J of the door body 200 is substantially flush with the side wall 130 of the cabinet 100, that is, in the larger door opening angle range, the door body 200 has moved relatively greatly toward the front side of the refrigerator relative to the cabinet 100, so that the first side edge J has exceeded the cabinet front wall 420, so that there is a sufficient safety distance between the first side edge J of the door body 200 and the cabinet side edge R, thereby reducing or eliminating the possibility of collision between the first side edge J and the cabinet 400. Although the movement of the door body 200 toward the inside of the refrigerator is relatively small in the first door opening stage, the purpose of the invention can still be achieved. In the second door opening stage, the door body 200 can move toward the front and outside of the refrigerator to a greater extent, and at the same time, the first side edge J of the door body 200 can move toward the front and outside of the refrigerator to a greater extent relative to the cabinet 100.

[0249] In other embodiments of the present disclosure, Fig.28 As shown in FIG. 1 , in the first door opening stage, FP may decrease or increase multiple times, that is, FP may fluctuate. For example, the fluctuation amplitude of FP Δfp 3 It can be less than 2 mm. In the second door opening stage, FP can be gradually increased.

[0250] Compared with the embodiment in which FP gradually increases, in the first door opening stage, within a small angle range, the door body 200 can move relatively greatly and quickly toward the front and inner side of the refrigerator. At the same time, the first side edge J of the door body 200 moves toward the front and inner side of the refrigerator relative to the cabinet 100, so that the first side edge J of the door body 200 does not exceed the side wall 130 of the cabinet 100. In the first door opening stage, within a small angle range, the first side edge J of the door body 200 moves inward. Although FP decreases slightly for many times, the first side edge J of the door body 200 slightly exceeds the side wall of the cabinet. However, in the first door opening stage, the door body 200 always moves toward the front side of the refrigerator relative to the cabinet 100, so that the first side edge J has exceeded the cabinet front wall 420, so that there is a sufficient safety distance between the first side edge J of the door body 200 and the cabinet side edge R, thereby reducing or eliminating the possibility of collision between the first side edge J and the cabinet 400. Although the movement of the door body 200 toward the inside of the refrigerator is relatively small in the first door opening stage, the purpose of the invention can still be achieved. In the second door opening stage, the door body 200 can move toward the front and outside of the refrigerator to a greater extent, and at the same time, the first side edge J of the door body 200 can move toward the front and outside of the refrigerator to a greater extent relative to the cabinet 100.

[0251] In some embodiments of the present disclosure, the process of opening the door body 200 may include a third door opening stage and a fourth door opening stage. The door opening angle α exceeds the third preset door opening angle α 3 , the fourth preset door opening angle α is not reached 4 , that is, α∈[α 3 , α 4 ), it is the third door opening stage. And the door opening angle α exceeds the fourth preset door opening angle α 4， To the maximum door opening angle α max , that is, α∈[α 4 , α max] It is the fourth door opening stage.

[0252] Among them, the fourth preset door opening angle α 4 Greater than the third preset door opening angle α 3 .

[0253] The third preset door opening angle α 3 It can be any angle between 10° and 30°. Fig.29 The third preset door opening angle α 3 It can be P point cross P 2 For example, the third preset door opening angle α 3 It can be 10°, 15° or 20°.

[0254] Fourth preset door opening angle α 4It can be any angle between 90° and 105°. Fig.29 The fourth preset door opening angle α 4 The fourth preset door opening angle α may be the door opening angle α when the distance between point P and the plane where the access opening of the box is located is the largest. For example, 4 It can be 90°, 98° or 105°.

[0255] In the third door opening stage, the orthographic projection length of the distance between the first reference point E and the axis point P in the direction perpendicular to the box front wall 110, that is, the orthographic projection length of EP in the direction y, continues to increase, so that the door body 200 is opened to the third preset door opening angle α 3 Afterwards, the point P moves relative to the box body 100 away from one side of the box body and the outside of the box body, so that the movement trend of the door body 200 is to move away from one side of the box body and the outside of the box body.

[0256] In the fourth door opening stage, the orthographic projection length of the distance between the first reference point E and the axis point P in the direction perpendicular to the box front wall 110, that is, the orthographic projection length of EP in the direction y, gradually decreases, so that the door body 200 is opened to the fourth preset door opening angle α 4 Afterwards, the point P moves relative to the box body 100 toward one side of the box body and the outside of the box body, so that the movement trend of the door body 200 is to move toward one side of the box body and the outside of the box body.

[0257] In the refrigerator of the related art, the door body 200 is opened to a third preset door opening angle α 3 Then to the maximum door opening angle α max During the process, the length of the positive projection of EP in the direction y gradually increases, and the door body 200 moves relative to the cabinet 100 toward the side of the cabinet away from the refrigerator and the outside of the cabinet.

[0258] In some embodiments of the present disclosure, since the door body 200 can have a larger opening angle α, the door body 200 can move toward the outside of the refrigerator to a greater extent. This is conducive to the door body 200 moving more toward the front and outside of the box body. In the process of the door body opening from a large angle to the maximum opening angle, there is more space for the door body 200 to move toward the side close to the box body, avoiding occupying more indoor space when the door body is opened to a large angle.

[0259] like Fig.29 As shown, assuming that when the refrigerator of the embodiment of the present disclosure increases only the first angle θ compared with the related art, the motion trajectory of the main trajectory point P is the motion trajectory p 1 , the motion trajectory of the auxiliary trajectory point Q is the motion trajectory q 1. The horizontal dotted line is the position of the door front wall 210 when the door body 200 is closed, recorded as the preset door front wall 210'. The vertical dotted line is the position of the first door side wall 230 when the door body 200 is closed, recorded as the preset first door side wall 230'. The preset door front wall 210' and the preset first door side wall 230' are fixed positions during the opening process of the door body 200. Point P' is located on the preset door front wall 210', and the distance between the first reference point E and point P' is equal to the distance between the first reference point E and the main trajectory point P when the door body 200 is closed, that is, EP=EP'. The main trajectory point P moves to point P on the preset door front wall 210'. 1 When point P' and point P 1 The distance between 1 The amount of movement of the main trajectory point P toward the inside of the refrigerator in the horizontal direction x can be used to characterize, to a certain extent, the amount of movement of the door body 200 toward the inside of the refrigerator in the horizontal direction x during the process of opening the door body 200 .

[0260] It should be noted that the technical solution of increasing the first angle θ in the embodiment of the present disclosure compared to the related art can achieve the purpose of the invention of increasing the maximum door opening angle. Although the movement of the door body toward the inside of the refrigerator is slightly reduced in the early stage of door opening, the movement of the door body 200 toward the front of the refrigerator will not be significantly reduced, and the reduced movement will not significantly reduce the distance between the first side edge J of the door body 200 and the cabinet side edge R, so that there is still a sufficient safety distance between the first side edge J of the door body 200 and the cabinet side edge R, which can reduce or eliminate the possibility of collision between the first side edge J of the door body 200 and the cabinet side edge R, and combined with the capabilities of those skilled in the art, the purpose of the invention can still be achieved.

[0261] like Fig.29 As shown, in some other embodiments of the present disclosure, the motion trajectory of the main trajectory point P can be improved. The motion trajectory p is the improved motion trajectory of the main trajectory point P. The main trajectory point P moves to the preset point P on the front wall 210' of the door. 2 When the main trajectory point P moves toward the inside of the refrigerator in the horizontal direction x, it is P'P 2 , P'P 2 Greater than P'P 1 That is to say, compared with the above-mentioned embodiment, this embodiment increases the movement amount of the main trajectory point P toward the inside of the refrigerator in the horizontal direction x, thereby increasing the movement amount of the door body 200 toward the inside of the refrigerator in the horizontal direction x during the process of opening the door body 200, thereby reducing the possibility of the portion of the door body 200 close to its first side edge J colliding with the accommodating side wall 411 of the cabinet 400 and the cabinet side edge R.

[0262] In some embodiments of the present disclosure, reference Fig.30 and Fig.36, the line between the axis point A and the axis point P when the door body 200 is closed, and the horizontal line x passing through the axis point A and parallel to the front wall 110 of the box 1 There is a fourth angle δ between them, and the fourth angle δ may be greater than or equal to 8°. Preferably, the fourth angle δ may be greater than 9°. Fig.32 , the fourth angle δ is 6-7°. Compared with the related art, the embodiment of the present disclosure increases the fourth angle δ. In the process of opening the door body 200, the main track point P moves to the horizontal line x 1 Point P on 3 When 3 The angle of counterclockwise rotation relative to EP is larger. The larger the angle, the greater the movement amount of the main track point P toward the inside of the refrigerator in the horizontal direction x, thereby increasing the movement amount of the door body 200 toward the inside of the refrigerator in the horizontal direction x.

[0263] If the fourth angle δ is less than 8°, the fourth angle δ is too small, and in the process of opening the door body 200, the main track point P will move to the horizontal line x 1 Point P on 3 When, EP 3 The counterclockwise rotation angle relative to EP is small. The smaller the angle, the smaller the movement of the main track point P toward the inside of the refrigerator in the horizontal direction x, which results in a smaller movement of the door body 200 toward the inside of the refrigerator in the horizontal direction x, making it easy for the door body 200 to collide with the accommodating side wall 411 of the cabinet 400 and the cabinet side edge R.

[0264] In some embodiments of the present disclosure, the fourth angle δ may be less than or equal to 15°. If the fourth angle δ is greater than 15°, the fourth angle δ is too large, and the main track point P is closer to the box front wall 110 when the door body is closed, so that at least part of the rods in the hinge assembly 300 are offset toward the box front wall 110, which easily leads to an excessive thickness H of the hinge assembly 300, thereby affecting the thermal insulation performance of the door body 200. Setting the fourth angle δ to be less than or equal to 15° is conducive to ensuring that the hinge assembly 300 has a sufficiently small thickness, thereby facilitating the miniaturization of the hinge assembly 300.

[0265] In some embodiments of the present disclosure, Fig.30 As shown, when the door body 200 is closed, the distance between the axis point A and the axis point P when the door body 200 is closed, that is, AP, can be greater than or equal to 12 mm. Fig.31 As shown in FIG. 1 , when the door body 200 is closed, the distance between the axis point A and the axis point P when the door body 200 is closed, that is, AP, is 11 mm. Compared with the related art, the embodiment of the present disclosure increases the distance between the axis point A and the axis point P when the door body 200 is closed, so that the axis point P is far away from the axis point A, so that AL is closer to the horizontal line x 1That is, there is a sufficiently large space on the side of the first rod 320 facing away from the front wall 110 of the box, which is conducive to increasing the fourth angle δ, thereby facilitating increasing the movement of the door body 200 toward the inside of the refrigerator in the horizontal direction x, and preventing the door body 200 from colliding with the cabinet 400 during the process of opening the door body 200.

[0266] If AP is less than 12 mm, AP is too small, which will make the axis point P closer to the axis point A when the door body 200 is closed, which is not conducive to increasing the fourth angle δ, and increases the difficulty of increasing the amount of movement of the door body 200 toward the inside of the refrigerator in the horizontal direction x, making it easy for the door body 200 to collide with the cabinet 400 during the process of opening the door body 200.

[0267] In some embodiments of the present disclosure, AP may be less than or equal to 16 mm. If AP is greater than 16 mm, AP is too large, and when the door is closed, the main track point P is closer to the box front wall 110, so that at least part of the rods in the hinge assembly 300 are offset toward the box front wall 110, which easily leads to the thickness H of the hinge assembly 300 being too large, thereby affecting the thermal insulation performance of the door 200. Setting AP to be less than or equal to 16 mm is conducive to ensuring that the hinge assembly 300 has a sufficiently small thickness, thereby facilitating the miniaturization of the hinge assembly 300.

[0268] In some embodiments of the present disclosure, Fig.32 As shown, the line between the axis point P and the axis point L and the line between the axis point L and the axis point M form a fifth angle β, and the fifth angle β is facing away from the front wall 110 of the box when the door body 200 is closed. In other words, the PLM can be bent and the PLM can face away from the front wall 110 of the box when the door body 200 is closed. By bending the PLM, the axis point L can be closer to the front wall 110 of the box when the door body 200 is closed, thereby increasing the distance between AL and the horizontal line x 1 The space between the first rod 320 allows a sufficiently large space on the side facing away from the front wall 110 of the box, which is beneficial to increasing the fourth angle δ, thereby facilitating increasing the movement of the door body 200 toward the inside of the refrigerator in the horizontal direction x, thereby preventing the door body 200 from colliding with the cabinet 400 during the process of opening the door body 200.

[0269] In some embodiments of the present disclosure, the fifth angle β may be less than or equal to 176°.

[0270] In some embodiments of the present disclosure, the fifth angle β may be greater than or equal to 170°.

[0271] In some embodiments of the present disclosure, Fig.33As shown, the first rod 320 can be bent, and the bending direction of the first rod 320 is away from the box front wall 110 when the door body 200 is closed. In other words, the first rod 320 can be bent in the direction away from the box front wall 110 when the door body 200 is closed. This arrangement can increase the distance between the first rod 320 and the horizontal line x when the door body 200 is closed. 1 The space between the first rod 320 allows a sufficiently large space on the side facing away from the front wall 110 of the box, which is beneficial to increasing the fourth angle δ, thereby facilitating increasing the movement of the door body 200 toward the inside of the refrigerator in the horizontal direction x, thereby preventing the door body 200 from colliding with the cabinet 400 during the process of opening the door body 200.

[0272] In other embodiments of the present disclosure, Fig.33 As shown, the first rod 320 may be provided with an avoidance recess on one side facing the sixth hinge shaft 376 when the door body 200 is closed, and the avoidance recess may be used to accommodate at least a portion of the sixth hinge shaft 376, at least a portion of the third rod 340, and at least a portion of the fifth rod 360. In this way, the distance between the first rod 320 and the horizontal line x when the door body 200 is closed can be increased. 1 The space between the first rod 320 allows a sufficiently large space on the side facing away from the front wall 110 of the box, which is beneficial to increasing the fourth angle δ, thereby facilitating increasing the movement of the door body 200 toward the inside of the refrigerator in the horizontal direction x, thereby preventing the door body 200 from colliding with the cabinet 400 during the process of opening the door body 200.

[0273] In some embodiments of the present disclosure, Fig.34 As shown in FIG. 1 , the portion of the second rod 330 between the axis point B and the axis point M, namely, BM, can be bent, and the bending direction of BM can be facing away from the box front wall 110 when the door body 200 is closed. In other words, BM can be bent in a direction facing away from the box front wall 110 when the door body 200 is closed. In this way, the space above BM can be increased when the door body 200 is closed, so as to provide a large enough space for the axis point L to move toward the box front wall 110, which is conducive to increasing the distance between AL and the horizontal line x 1 The space between the door body 200 and the cabinet 400 is further conducive to increasing the fourth angle δ, thereby increasing the movement of the door body 200 toward the inside of the refrigerator in the horizontal direction x, preventing the door body 200 from colliding with the cabinet 400 during the process of opening the door body 200.

[0274] In some embodiments of the present disclosure, Fig.35 As shown, at least part of the rods in the hinge assembly 300 can be bent, which will not be described in detail here.

[0275] like Fig.40As shown, in the motion track j of the first side edge J, in the process from closing the door body 200 to opening the door body 200, the first side edge J can first move toward the front and inner side of the refrigerator relative to the cabinet 100. Then, when the door body 200 is opened to a certain door opening angle α, the first side edge J starts to move toward the front and outer side of the refrigerator.

[0276] One of the technical problems to be solved in the embodiment of the present disclosure is to avoid interference between the first side edge J and the cabinet 400 during the process of opening the door body 200, and to ensure that a sufficient safety distance is always maintained between the first side edge J and the cabinet 400 to avoid collision. Fig.12 As shown, within a certain door opening angle range, it is necessary to ensure that AP and BP have a large length increase, so that as the door opening angle α gradually increases, point P can move toward the inside of the refrigerator, and at the same time, point P can move toward the front of the refrigerator to a greater extent, so that when the door body 200 is opened to a smaller door opening angle α, there is a safety distance between the first side edge point J of the door body 200 and the cabinet 400 that is large enough to avoid collision.

[0277] In some embodiments of the present disclosure, Fig.12 As shown, in order to make point P move toward the inside of the refrigerator and move toward the front of the refrigerator at a relatively large extent, it is necessary to make BP have a relatively large length increase when the door body 200 is opened at a relatively small door opening angle α. If BP has a relatively large length increase when the door body 200 is opened at a relatively small door opening angle α, the key is that BM / PM=n, or, when the door body 200 is opened at a relatively small door opening angle α, The rate of increase.

[0278] In some embodiments of the present disclosure, Fig.37 and Fig.38 As shown, the angle between the line connecting the axis point P of the sixth hinge axis 376 and the axis point Q of the seventh hinge axis 377, and the line connecting the axis point A of the first hinge axis 371 and the axis point Q of the seventh hinge axis 377, that is, PQ and AQ, can be a sixth angle λ. In the process of the door body 200 being closed to opened, the sixth angle λ gradually decreases.

[0279] In some embodiments of the present disclosure, when the door body 200 is opened to an opening angle α of 110°, the sixth angle λ may be greater than 0°, and the axis point P of the sixth hinge axis 376 may be located outside the line between the axis point B of the second hinge axis 372 and the axis point Q of the seventh hinge axis 377. In other words, Fig.37 and Fig.38 As shown, when the door body 200 is opened to 110°, the sixth angle λ may be greater than 0°, and the axis point P of the sixth hinge shaft 376 may be located on the side of BQ close to the outside.

[0280] In the process of the door body 200 from closing to opening to a larger door opening angle α, since the axis point P of the sixth hinge shaft 376 is always located outside AQ and the sixth angle λ is greater than 0°, a sufficiently large angle can always be maintained between PQ and AQ, thereby avoiding as much as possible the door body 200 from opening to the maximum door opening angle α. max The overlap of PQ and AQ before allows the quadrilateral PQBA formed in the hinge assembly 300 to always maintain a relatively stable shape, so that the hinge assembly 300 can support the door body more stably. Secondly, the axis point P of the sixth hinge shaft 376 is always located outside AQ, which can make the axis point P closer to the outside, so that the third rod 340 and the axis point M can be fully offset to the outside, so that the fourth hinge shaft 374 and its axis point M can be fully offset to the outside, so as to minimize the obstruction of the fourth hinge shaft 374 and its axis point M to the access port, which is conducive to increasing the theoretically designed maximum door opening angle α max design possibilities.

[0281] In some embodiments of the present disclosure, when the door body 200 is opened to an opening angle of 110°, the sixth angle λ may be greater than 5°. The axis point P of the sixth hinge axis 376 may be located on the side close to the outside of BQ. In this way, the angle between PQ and AQ can always be large enough to avoid the door body 200 opening to the maximum opening angle α. max Previously, PQ overlapped with AQ. That is to say, during the process of opening the door body 200, the sides of the quadrilateral PQBA can always remain non-overlapping, and the quadrilateral PQBA has a stable shape, so that the hinge assembly 300 has a certain width on the horizontal plane to prevent the door body 200 from rotating around the horizontal direction as much as possible, thereby improving the stability of the door body 300 during the opening process. If the sixth angle λ is too small, when the door body 200 is opened to a larger door opening angle α, the sides of the quadrilateral PQBA approximately form a straight line, which will reduce the width of the hinge assembly 300 on the horizontal plane, making it easy for the door body 200 to rotate around the horizontal direction, and the door body 200 is easy to shake, reducing the stability of the door body 200 during the opening process.

[0282] In some embodiments of the present disclosure, when the door body 200 is opened to an opening angle of 110°, the sixth angle λ may be less than 15°. The axis point P of the sixth hinge axis 376 may be located on the side of BQ close to the outside. When the door body is opened to a predetermined opening angle, such as 110°, the sixth angle λ is positively correlated with the first angle θ. Specifically, Fig.38 As shown, when the first angle θ increases, it is equivalent to rotating the hinge assembly 300 counterclockwise around the axis point A of the first hinge shaft 371, which can increase the maximum door opening angle α of the door body 100 when the quadrilateral PQBA has a stable shape. maxSince the quadrilateral PQBA has a stable shape, a larger angle can be formed between PQ and QA, that is, the sixth angle λ is larger, that is, the sixth angle λ is positively correlated with the first angle θ.

[0283] Since the sixth angle λ is positively correlated with the first angle θ, the larger the first angle θ is, the larger the sixth angle λ is. When the first angle θ is too large, as described above, in the process of opening the door body 200, the first side edge J of the door body 200 is easy to collide with the cabinet front wall 420 of the cabinet 400, and it is not conducive to the overall miniaturization of the hinge assembly 300. Therefore, setting the first angle λ to be less than 15° can avoid the first angle θ being too large as much as possible, thereby helping to avoid the first side edge J from colliding with the cabinet front wall 420 of the cabinet 400 in the process of opening the door body 200, and is conducive to the overall miniaturization of the hinge assembly 300.

[0284] In some embodiments of the present disclosure, Fig.37 and Fig.38 As shown, the second ratio n of the distance between the pivot point B and the pivot point M to the distance between the pivot point M and the pivot point P, that is, BM / PM=n, n may be less than 1.0. Fig.39 As shown, if the door body 200 is opened at a small opening angle α, BP has a large length increase, and it is necessary to ensure that BM / PM=n is not too large. If n is too large, when the door body 200 is opened at a small opening angle α, BP has a small length increase.

[0285] Similarly, in the embodiments of the present disclosure, if Fig.37 and Fig.38 As shown, the second ratio n of the distance between the pivot point B and the pivot point M and the distance between the pivot point M and the pivot point P, that is, BM / PM=n, n can be less than 1.0. Setting n to be less than 1.0 is conducive to increasing the movement amount of the main track point P toward the outside of the refrigerator in the horizontal direction x, thereby facilitating increasing the movement amount of the door body 200 toward the outside of the refrigerator in the horizontal direction x during the process of opening the door body 200, thereby preventing the door body 200 from colliding with the cabinet 400.

[0286] If the second ratio n is greater than or equal to 1.0, the second ratio n is too large, which is not conducive to increasing the movement of the main trajectory point P in the horizontal direction x and the vertical direction y toward the outside and front of the refrigerator when the door body 200 is opened to a small angle range, and is therefore not conducive to increasing the movement of the door body 200 in the horizontal direction x toward the outside of the refrigerator during the process of opening the door body 200, thereby increasing the risk of collision between the door body 200 and the cabinet 400.

[0287] In some embodiments of the present disclosure, n may be greater than or equal to 0.85. Preferably, n may be greater than or equal to 0.9.

[0288] If n is further reduced, the length of BM needs to be shortened or the length of PM needs to be increased. If n is less than 0.85 or 0.9, n is too small, which will cause BM to be too short or PM to be too long.

[0289] If BM is too short, the sum of BM and PM will be reduced. When the opening angle α of the door body 200 is large, the movement of the main trajectory point P relative to the cabinet 100 toward the outside of the refrigerator will be reduced, which is not conducive to increasing the movement of the door body 200 relative to the cabinet 100 toward the outside of the refrigerator during the process of opening the door body 200.

[0290] If PM is too long, the axis point M will be close to the front wall 110 when the door body 200 is closed, which will cause the thickness H of the hinge assembly 300 to be too large, which is not conducive to the miniaturization of the hinge assembly 300. Therefore, setting the value of n to be greater than or equal to 0.85, or greater than or equal to 0.9, is conducive to increasing the amount of movement of the door body 200 relative to the cabinet 100 toward the outside of the refrigerator during the process of opening the door body 200, and is conducive to the miniaturization of the hinge assembly 300.
