[0055] Hereinafter, the present application will be described in detail by exemplary embodiments. It should be understood, however, that the elements, structures and features of one embodiment can be beneficially incorporated into other embodiments without further recitation.

[0056] In the description of the present application, it is to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are merely used for convenience of describing the present application and simplifying the description, and thus cannot be construed as indicating or implying that a specific orientation is required for the device or element indicated thereby, constructed and operated in a particular orientation, and thus cannot be construed as limiting the present application.

[0057] The terms "first", "second", and the like are used only for the purpose of description, and cannot be construed as indicating or implying relative importance or implying the number of the technical features indicated thereby. Thus, the features defined with "first", "second", and the like can explicitly or implicitly include one or more of the features.

[0058] In the description of the present application, it is to be noted that the terms "mounting", "connection", "connecting" should be understood broadly unless otherwise explicitly specified and limited, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium, can be the internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0059] In the following, the embodiments of the present application will be described in detail with reference to the accompanying drawings. In the drawings, the side facing the user when the refrigerator is used is defined as the front side, and the side opposite thereto is defined as the rear side.

[0060] Referring to Figure 1 and Figure 2 , the refrigerator 1 according to one embodiment of the present application includes a cabinet 10, a storage compartment formed at the inner side of the cabinet 10, a cold air supply device that generates cold air, and a door body 20 that opens and closes the storage compartment.

[0061] The cabinet 10 is substantially in the shape of a rectangular box, and includes a cabinet body and an outer shell. The storage compartment is formed at the inner side of the cabinet body, and the outer shell is located outside the cabinet body. A foamed insulation material configured to insulate the storage compartment can be filled between the cabinet body and the outer shell.

[0062] The storage compartment can be divided into an upper storage compartment and a lower storage compartment by a middle partition wall. The upper storage compartment can be used as a refrigerating chamber, and the lower storage compartment can be used as a freezing chamber. Alternatively, the upper storage compartment can be used as a freezing chamber, and the lower storage compartment can be used as a refrigerating chamber.

[0063] However, unlike the present embodiment, the refrigerator can be provided with a vacuum chamber, a variable temperature chamber, etc., and the aspects of the present application can be similarly applied.

[0064] The storage compartment can be provided with an opening at the front surface thereof to store or take out foodstuffs. The opening can be opened or closed by the door body 20. The storage compartment can be opened or closed by a plurality of rotating door bodies 20. In other embodiments, the storage compartment can also be opened or closed by a drawer-type door body provided to be inserted into and pulled out of the storage compartment.

[0065] The cold air supply device is provided to form cold air by circulating a cooling circuit, and can supply the generated cold air to the storage compartment. The cold air supply device can include a cooling circuit device having a compressor, a condenser, a capillary, and an evaporator assembly, a refrigerant pipe that guides a refrigerant into each of the cooling circuit devices, and a fan (not shown) that forcibly circulates air to supply the cold air generated at the evaporator assembly to the storage compartment.

[0066] The door body 20 can be connected to the cabinet 10 through a hinge assembly 30. Generally, the hinge assembly 30 is arranged at the left end or / and the right end of the cabinet 10.

[0067] For the convenience of description, the side of the door body 20 near the hinge assembly 30 is referred to as a side wall 21. For example, in the current example, the hinge assembly 30 is arranged at the right end of the cabinet 10, and the right side of the door body 20 is the side wall 21, and the left end of the door body 20 rotates about the right end as the rotation center. The front wall 22 of the door body 20 and the side wall 21 meet to form a corner 23.

[0068] In other embodiments, when the hinge assembly 30 is arranged at the left end of the cabinet 10, the left side of the door body 20 is the side wall 21, and the right end of the door body 20 rotates about the left end as the rotation center.

[0069] The plane in which the side of the cabinet 10 near the hinge assembly 30 is arranged is defined as a reference plane O. With the reference plane O as the boundary surface, one side of the cabinet 10 is the inner side, and the other side is the outer side. For the hinge assembly 30 arranged at the right side of the door body 20, the inner side is the left side of the reference plane O; for the hinge assembly 30 arranged at the left side of the door body 20, the inner side is the right side of the reference plane O.

[0070] When the hinge assembly 30 is a single-axis hinge, that is, the door body 20 only rotates about an axis. Generally, when the door body 20 is in the closed state, the side wall 21 of the door body 20 is flush with the reference plane O, and when the door body 20 rotates about the single axis, the corner 23 will rotate to the outer side of the reference plane O. If the refrigerator is embedded in the cabinet 100 for use, the corner 23 will exceed the reference plane O too much, which will cause the corner 23 to collide with the cabinet 100 and make the door body 20 unable to be normally opened.

[0071] Therefore, in order to enable the refrigerator to be embedded in the cabinet for use, the door body 20 needs to be able to move to the inner side during rotation, so that the corner 23 of the door body 20 will not exceed the reference plane O too much during the opening and closing process.

[0072] According to the embodiments of the refrigerator of the present application, the hinge assembly 30 adopts the form of a double-axis hinge, and the requirement that the door body 20 can move to the inner side during rotation is met through the combination of the trajectories of the two axes.

[0073] Specifically, referring to Figure 3 , the hinge assembly 30 includes a first shaft 41 and a first groove 50 that cooperate with each other, and a second shaft 42 and a second groove 60 that cooperate with each other. During the opening and closing process of the door body 20, the first shaft 41 moves relative to the first groove 50, and the second shaft 42 moves relative to the second groove 60.

[0074] Since the first slot 50 and the first shaft 41 are in relative motion, and the second slot 60 and the second shaft 42 are in relative motion, if the first slot 50 and the second slot 60 are taken as the static reference, it is equivalent to that the first shaft 41 moves in the first slot 50, and the second shaft 42 moves in the second slot 60. In order to facilitate the description, the first slot 50 and the second slot 60 are taken as the reference, and the first shaft 41 and the second shaft 42 move relative to the reference.

[0075] In the first embodiment of the present application, the first shaft 41 and the second shaft 42 are fixed relative to the cabinet 10, and the first slot 50 and the second slot 60 are located on the door body 20.

[0076] Specifically, the hinge assembly 30 includes a hinge plate 40 fixedly connected to the cabinet 10. The rear end portion of the hinge plate 40 can be connected to the cabinet by screws, and the front end portion of the hinge plate 40 extends forward beyond the cabinet 10. The first shaft 41 and the second shaft 42 are arranged at the front end portion of the hinge plate 40 and extend vertically.

[0077] Referring to Figure 4 , an example of the relative positions of the first shaft 41 and the second shaft 42 is shown in the figure: when the door body 20 is in the closed state, the first shaft 41 is farther away from the front wall 22 and closer to the side wall 21 than the second shaft 42. The thickness of the door body 20 can be between 44mm and 53mm. Those skilled in the art can understand that the size parameters of the positions of the first shaft 41 and the second shaft 42 shown in the figure can be adjusted within a certain range, and cannot be regarded as a limitation on the protection scope of the present application.

[0078] Referring to Figure 5 , the first slot 50 is located substantially between the front end of the second slot 60 and the side wall 21. In the direction from the inside to the outside, the first slot 50 is a straight slot extending toward the side wall 21, and the extension direction of the straight slot is perpendicular to the side wall 21. The second slot 60 includes a first guide slot section 601 and a second guide slot section 602. The first guide slot section 601 extends away from the front wall 22 and away from the side wall 21, and the second guide slot section 602 extends from the end of the first guide slot section 601 away from the front wall 22 and closer to the side wall 21. When the door body 20 is opened from the closed state to 90°, the second shaft 42 moves in the first guide slot section 601 and the second guide slot section 602.

[0079] In other embodiments, the first guide slot section 601 can also extend away from the front wall 22 and closer to the side wall 21.

[0080] In order to take into account the normal use of the refrigerator (not placed in the cabinet), that is, the door body 20 can be opened to a larger angle from 90°, the second slot 60 can include a third guide slot section 603, which extends from the end of the second guide slot section 602 closer to the front wall 22 and closer to the side wall 21.

[0081] The structure of the hinge assembly 30 will be described in detail below with reference to the process of opening the door body 20:

[0082] First stage

[0083] With reference to Figure 6 , the first slot 50 includes a first positioning position 51 and a second positioning position 52, and the second positioning position 52 is farther away from the side wall 21 than the first positioning position 51; the second slot 60 includes a first guiding position 61 and a second guiding position 62, and the second guiding position 62 is farther away from the front wall 22 and the side wall 21 than the first guiding position 61.

[0084] When the door body 20 is in the closed state, the first shaft 41 is located at the first positioning position 51, and the second shaft 42 is located at the first guiding position 61. Among them, the first positioning position 51 is not at the end of the first slot 50, and the first guiding position 61 can be located at the front end of the second slot 60.

[0085] When the door body 20 is in the first angle state (as shown in the state), the first shaft 41 is located at the second positioning position 52, and the second shaft 42 is located at the second guiding position 62. Figure 6

[0086] Therefore, when the door body 20 is opened from the closed state to the first angle, the first shaft 41 moves from the first positioning position 51 to the second positioning position 52 relative to the first slot 50, and the second shaft 42 moves from the first guiding position 61 to the second guiding position 62 relative to the second slot 60.

[0087] Since the first shaft 41 moves from the first positioning position 51 to the second positioning position 52 in the direction away from the side wall 21 (the inner side), it is equivalent to the first slot 50 moving outward for the door body 20. Therefore, in the first stage of the embodiment, the door body 20 will move outward when it is just opened.

[0088] With reference to Figure 2 , generally, when the refrigerator is placed in the cabinet 100 for use, in order to prevent the user's ground from being uneven and the cabinet from being deformed due to factors such as this, the cabinet is usually set to have a certain gap α from the side of the refrigerator (reference plane O), and α is about 5 mm.

[0089] In the embodiment, the distance between the first positioning position 51 and the second positioning position 52 is relatively small, that is, in the first stage, the door body 20 moves slightly outward. Since the corner edge 23 of the door body 20 just after opening exceeds the reference plane O by a particularly small distance, even if the door body 20 moves slightly outward, it will not interfere with the cabinet.

[0090] Specifically, when the door body 20 is in the first angle state, the distance β1 by which the corner edge 23 exceeds the reference plane O is less than α.​

[0091] In the current example, the movement trajectory line of the second shaft 42 between the first guide position 61 and the second guide position 62 is a first guide trajectory line 612, which is a spline curve extending away from the front wall 22 and away from the side wall 21 (here, the extending direction refers to the movement direction of the shaft relative to the groove). In other embodiments, the first guide trajectory line 612 can be a straight line segment.

[0092] It should be noted that the display of the movement trajectory line in the drawings herein takes the center of the first shaft 41 and the second shaft 42 as the reference point.

[0093] In this stage, the door body 20 is slightly moved outward, the first guide trajectory line 612 extends away from the front wall 22 and away from the side wall 21, which can achieve the case that the curvature of the first guide groove segment 601 and the second guide groove segment 602 changes, so that the inflection points of the first guide groove segment 601 and the second guide groove segment 602 are relatively smooth (described below), and the smoothness of the movement of the door body 20 is improved.

[0094] In addition, the extension of the first guide trajectory line 612 away from the front wall 22 and away from the side wall 21 increases the included angle between the first guide trajectory line 612 and the movement trajectory line of the first shaft 41, which ensures that the door body 20 does not shake during movement.

[0095] Specifically, the included angle between the first guide trajectory line 612 and the movement trajectory line of the first shaft 41 is > 45°.

[0096] In the first stage, the first angle of opening of the door body 20 is about 7° or so.

[0097] In other embodiments, the first stage can also be configured such that the second positioning position 52 is closer to the side wall 21 than the first positioning position 51, the second guide position 62 is farther away from the front wall 22 and closer to the side wall 21 than the first guide position 51, that is, the first guide trajectory line 612 extends away from the front wall 22 and closer to the side wall 21, and the door body 20 moves inward by a distance.

[0098] Second stage

[0099] Referring to Figure 7 , the first groove 50 further has a third positioning position 53, which is closer to the side wall 21 than the second positioning position 52 (and the first positioning position 51); the second groove 60 further has a third guide position 63, which is farther away from the front wall 22 and closer to the side wall 21 than the second guide position 62.

[0100] When the door body 20 is in the second angle of opening state Figure 7When the door body 20 is in the second angle state, the first shaft 41 is in the third positioning position 53, and the second shaft is in the third guiding position 63. The third positioning position 53 can be located on the first groove 50 close to the end of the side wall 21.

[0101] When the door body 20 is continuously opened from the first angle to the second angle, the first shaft 41 moves from the second positioning position 52 to the third positioning position 53 relative to the first groove 50, and the second shaft 42 moves from the second guiding position 62 to the third guiding position 63 relative to the second groove 60.

[0102] Since the first shaft 41 moves from the second positioning position 52 to the third positioning position 53 in the direction close to the side wall 21 (the outer side), it is equivalent to that the door body 20 drives the first groove 50 to move inward. Therefore, in the second phase of the embodiment, the door body 20 moves inward by a distance while rotating, so that the corner edge 23 moves inward relative to the reference plane O, avoiding the collision between the corner edge 23 and the cabinet 100.

[0103] When the door body 20 is in the second angle state, the distance β2 by which the corner edge 23 exceeds the reference plane O is less than α. In other embodiments, the corner edge 23 can also be designed to move to the inner side of the reference plane O, so that the door body 20 needs to move inward by a larger distance in the second phase, which will affect the hand feeling and fluency of opening the door.

[0104] The movement trajectory line of the second shaft 42 between the second guiding position 62 and the third guiding position 63 is a second guiding trajectory line 623. The second guiding trajectory line 623 is generally a curved segment extending in the direction away from the front wall 22 and close to the side wall 21. In other embodiments, the second guiding trajectory line 623 can also be a straight line.

[0105] In some embodiments of the present application, the distance of lateral movement of the door body 20 per unit angle in the first phase is μ1, and the distance of lateral movement of the door body 20 per unit angle in the second phase is μ2, μ1<μ2, that is, the lateral movement amplitude of the door body 20 in the first phase when the door body 20 is just opened is relatively small, so that the lateral friction between the door seal on the rear surface of the door body 20 and the front surface of the cabinet 10 caused by the large lateral movement distance per unit angle when the door body 20 is just opened can be avoided.

[0106] In addition, if the lateral movement distance per unit angle of the door body 20 when the door body 20 is just opened is large, the hand feeling and fluency of opening the door will be affected, so the lateral movement distance of the door body 20 when the door body 20 is just opened can be set to be small.

[0107] Specifically, the slope of the first guiding trajectory line 612 can be greater than the slope of the second guiding trajectory line 623 (the slopes described herein are absolute values). The greater the slope is set, the smaller the distance of lateral movement per unit angle of the door body is.

[0108] The length of the first guide track line 612 is smaller than the second guide track line 623. Thus, in the first stage, the door body 20 rotates so that the door seal does not contact the cabinet body. In the second stage, a larger lateral displacement can occur to avoid the cabinet.

[0109] If the door body 20 moves inward laterally in both the first and second stages, since the curvature of the motion trajectory of the second axis in the two stages needs to change, a sharp point may be generated at the connection between the first guide trajectory 612 and the second guide trajectory 623, affecting the feel of opening the door. Therefore, setting the door body 20 to move laterally outward in the first stage can make the connection between the first guide trajectory 612 and the second guide trajectory slightly smoother.

[0110] In some embodiments of the present application, the angle between the second guide trajectory line 623 and the motion trajectory line of the first axis 41 is greater than 45°, which can avoid the problem of shaking when the movement trends of the two axes are close to parallel, and ensure that the door body 20 does not shake during movement.

[0111] In the second stage, the second angle is approximately 45° to 50°.

[0112] Phase 3

[0113] Reference Figure 8 The first groove 50 also has a fourth positioning position 54, which is farther away from the side wall 21 than the third positioning position 53; the second groove 60 also has a fourth guide position 64, which is farther away from the front wall 22 than the third guide position 63 and closer to the side wall 21.

[0114] When the door body 20 is in the 90° open state ( Figure 8 As shown in the state), the first shaft 41 is located at the fourth positioning position 54 and the second shaft 42 is located at the fourth guiding position 64.

[0115] When the door body continues to open from the second angle to the 90° state, the first shaft 41 moves from the third positioning position 53 to the fourth positioning position 54 , and the second shaft 42 moves from the third guide position 63 to the fourth guide position 64 .

[0116] Since the first shaft 41 moves from the third positioning position 53 to the fourth positioning position 54 in a direction away from the side wall 21 (inward), the door body 20 drives the first slot 50 to move outward. Therefore, in the third stage, the door body 20 moves outward while rotating open.

[0117] The door 20 has passed the dangerous period of interfering with the cabinet in the second stage, so even if the door 20 moves outward during this stage, it will not touch the cabinet. In addition, moving outward can reduce the obstruction of the storage compartment by the door 20, thereby avoiding the door 20 restricting the withdrawal of the drawer in the storage compartment.

[0118] The motion trajectory of the second shaft 42 between the third guide position 63 and the fourth guide position 64 is a third guide trajectory 634. The third guide trajectory 634 is generally a curved segment extending away from the front wall 22 and toward the side wall 21. In other embodiments, the third guide trajectory 634 may also be a straight line.

[0119] In some embodiments, when the door body 20 is in the 90° open state, the front wall 22 can be flush with the reference plane O, which can minimize the space occupied by the door body 20 in front of the storage compartment, thereby avoiding the impact of the door body 20 on the extraction of drawers in the storage compartment.

[0120] In other embodiments, when the door body 20 is in the open 90° state, the door body 20 as a whole is located on the inner side of the reference plane O, that is, there is a gap between the front wall 22 of the door body 20 and the reference plane O. In this way, even if the door body 20 continues to open to a certain angle from 90°, it will not interfere with the cabinet, so that the refrigerator of the present application can be opened >90° when embedded in the cabinet for use.

[0121] Stage 4

[0122] Reference Figure 9 The first groove 50 also has a fifth positioning position 55, which is farther away from the side wall 21 than the fourth positioning position 54; the second groove 60 also has a fifth guide position 65, which is farther away from the front wall 22 than the fourth guide position 64 and closer to the side wall 21.

[0123] When the door body 20 is in the third open angle state ( Figure 9 As shown in the state), the first shaft 41 is located at the fifth positioning position 55 and the second shaft 42 is located at the fifth guiding position 65.

[0124] When the door body continues to open from 90° to the third angle state, the first shaft 41 moves from the fourth positioning position 54 to the fifth positioning position 55, the second shaft 42 moves from the fourth guide position 64 to the fifth guide position 65, and the door body 20 moves to the upper left.

[0125] The motion trajectory of the second shaft 42 between the fourth guide position 64 and the fifth guide position 65 is a fourth guide trajectory 645. The fourth guide trajectory 645 is generally a curved segment extending away from the front wall 22 and toward the side wall 21. In other embodiments, the fourth guide trajectory 645 may also be a straight line.

[0126] In some embodiments of the present application, the angle between the fourth guide trajectory line 645 and the motion trajectory line of the first axis 41 is greater than 45°, which can avoid the problem of shaking when the movement of the two axes is close to parallel, and ensure that the door body 20 does not shake during the movement.

[0127] The third angle may be the maximum angle to which the door 20 can be opened when the refrigerator is embedded in a cabinet.

[0128] Stage 5

[0129] Reference Figure 10 The first slot 50 further includes a sixth positioning position 56 , which is further away from the side wall 21 than the fifth positioning position 55 ; the second slot 60 further includes a sixth guide position 66 , which is closer to the front wall 22 and the side wall 21 than the fifth guide position 65 .

[0130] When the door body 20 is at the maximum opening angle ( Figure 10 In the state shown in FIG, the first shaft 41 is located at the sixth positioning position 56, and the second shaft 42 is located at the sixth guiding position 66. The sixth positioning position 56 can be located at the end of the first slot 50 away from the side wall 21, and the sixth guiding position 66 can be located at the end of the second slot 60 close to the side wall 21.

[0131] When the door body 20 continues to open from the third angle to the maximum angle, the first shaft 41 moves from the fifth fixed position 55 to the sixth fixed position 56, the second shaft 42 moves from the fifth guide position 65 to the sixth guide position 66, and the door body 20 moves to the upper left.

[0132] The motion trajectory of the second shaft 42 between the fifth guide position 65 and the sixth guide position 66 is a fifth guide trajectory 656. The fifth guide trajectory 656 is generally a curved segment extending toward the front wall 22 and toward the side wall 21. In other embodiments, the fifth guide trajectory 656 may also be a straight line.

[0133] In some embodiments of the present application, the angle between the fifth guide trajectory line 656 and the motion trajectory line of the first axis 41 is greater than 45°, which can avoid the problem of shaking when the two axes move close to parallel, and ensure that the door body 20 does not shake during movement.

[0134] In the embodiment of the present application, the door body 20 rotates around a variable point during the opening process, and the variable point has a traceable trajectory, which is (X = (X1 + X2) / 2, Y = (Y1 + Y2) / 2); where X represents the distance from the variable point to the door body side wall; Y represents the distance from the variable point to the door body front wall. The motion trajectory of the variable point can be calculated using the following formula:

[0162] According to some embodiments of the present application, referring to Figure 17 to Figure 19 The door body 20 is provided with a receiving groove 24 at a position corresponding to the hinge assembly 30, and the front end of the hinge plate 40 extends into the receiving groove 24.

[0163] The first groove 50 and the second groove 60 on the door body 20 are provided on the mounting block 60, and the mounting block 60 is assembled in the mounting groove at the bottom of the receiving groove 24. The mounting block 60 can be made of POM material, which has good wear resistance.

[0164] In the second embodiment of the present application, a sliding block 410 is arranged between the first shaft 41 and the first slot 50. The sliding block 410 is sleeved on the first shaft 41, and is inserted into the first slot 50 to be slidingly connected with the first slot 50. During the opening and closing of the door body 20, the door body 20 rotates to drive the first slot 50 and the sliding block 410 to rotate relative to the first shaft 41, and the lateral movement of the door body 20 causes the first slot 50 to move relative to the sliding block 410.

[0165] In the second embodiment of the present application, a sliding block 410 is arranged between the first shaft 41 and the first slot 50. The sliding block 410 is sleeved on the first shaft 41, and is inserted into the first slot 50 to be slidingly connected with the first slot 50. During the opening and closing of the door body 20, the door body 20 rotates to drive the first slot 50 and the sliding block 410 to rotate relative to the first shaft 41, and the lateral movement of the door body 20 causes the first slot 50 to move relative to the sliding block 410.

[0166] In the second embodiment of the present application, a sliding block 410 is arranged between the first shaft 41 and the first slot 50. The sliding block 410 is sleeved on the first shaft 41, and is inserted into the first slot 50 to be slidingly connected with the first slot 50. During the opening and closing of the door body 20, the door body 20 rotates to drive the first slot 50 and the sliding block 410 to rotate relative to the first shaft 41, and the lateral movement of the door body 20 causes the first slot 50 to move relative to the sliding block 410.

[0167] In the second embodiment of the present application, a sliding block 410 is arranged between the first shaft 41 and the first slot 50. The sliding block 410 is sleeved on the first shaft 41, and is inserted into the first slot 50 to be slidingly connected with the first slot 50. During the opening and closing of the door body 20, the door body 20 rotates to drive the first slot 50 and the sliding block 410 to rotate relative to the first shaft 41, and the lateral movement of the door body 20 causes the first slot 50 to move relative to the sliding block 410.

[0168] In the second embodiment of the present application, a sliding block 410 is arranged between the first shaft 41 and the first slot 50. The sliding block 410 is sleeved on the first shaft 41, and is inserted into the first slot 50 to be slidingly connected with the first slot 50. During the opening and closing of the door body 20, the door body 20 rotates to drive the first slot 50 and the sliding block 410 to rotate relative to the first shaft 41, and the lateral movement of the door body 20 causes the first slot 50 to move relative to the sliding block 410.

[0169] In the third embodiment of the present application, referring to Figure 20 to Figure 27 , the first slot 50 and the second slot 60 can be directly arranged on the door body 20, that is, the first slot 50 and the second slot 60 are integrally formed with the door body 20, and the structure of the mounting block 25 is omitted.

[0170] In the third embodiment of the present application, referring to Figure 20 to Figure 27 , the first slot 50 and the second slot 60 can be directly arranged on the door body 20, that is, the first slot 50 and the second slot 60 are integrally formed with the door body 20, and the structure of the mounting block 25 is omitted.

[0171] In addition, referring to Figure 22 , the dotted line is the position of the double grooves when they are arranged on the mounting block, and the solid line is the position of the double grooves in the embodiment. Due to the forward movement of the double grooves, the distance from the grooves to the corner edge 23 is reduced, and the distance by which the corner edge 23 exceeds the reference plane when the door body rotates is also correspondingly smaller, i.e., X2 < X1 in the illustration. In this way, the double-groove structure in the embodiment can reduce the risk of the door body touching the cabinet; the transverse movement distance of the door body can also be reduced, thereby ensuring the smoothness of the opening and closing of the door body.

[0172] Referring to Figure 23 When the door body 20 is opened from the closed state to a first angle, the door body 20 drives the first shaft 41 to move from the first positioning position 51 to the second positioning position 52 relative to the first groove 50, and the second shaft 42 moves from the first guide position 61 to the second guide position 62 relative to the second groove 60, wherein the second positioning position 52 is closer to the side wall 21 than the first positioning position 51, and the second guide position 62 is farther away from the front wall 22 and closer to the side wall 21 than the first guide position 61.

[0173] Since the first shaft 41 moves from the first positioning position 51 to the second positioning position 52 in a direction (the outer side) closer to the side wall 21, the door body 20 moves inward while rotating.

[0174] In other embodiments, the arrangement in this stage can be the same as in the first embodiment, i.e., the second positioning position 52 is farther away from the side wall 21 than the first positioning position 51, and the second guide position 62 is farther away from the front wall 22 and farther away from the side wall 21 than the first guide position 61, and the door body 20 moves outward while rotating.

[0175] Referring to Figure 24 When the door body 20 is opened from the first angle to a second angle, the door body 20 drives the first shaft 41 to move from the second positioning position 52 to the third positioning position 53 relative to the first groove 50, and the second shaft 42 moves from the second guide position 62 to the third guide position 63 relative to the second groove 60, wherein the third positioning position 53 is closer to the side wall 21 than the second positioning position 52, and the third guide position 63 is farther away from the front wall 22 and closer to the side wall 21 than the second guide position 62, and the door body 20 moves inward while rotating.

[0176] The distance of transverse movement per unit angle of rotation during the process of opening the door body 20 from the closed state to the first angle is μ1, and the distance of transverse movement per unit angle of rotation during the process of opening the door body 20 from the first angle to the second angle is μ2, μ1 < μ2, so that the amplitude of transverse movement of the door body 20 when it is just opened is relatively small, avoiding friction between the door seal and the cabinet and affecting the opening hand feeling.

[0177] Specifically, the trajectory of the second shaft 42 relative to the second slot 60 from the first guide position 61 to the second guide position 62 is a first guide trajectory 612, and the trajectory of the second shaft 42 relative to the second slot 60 from the second guide position 62 to the third guide position 63 is a second guide trajectory 623. The slope of the first guide trajectory 612 is greater than that of the second guide trajectory 623, so that the lateral movement distance of the door body 20 is small.

[0178] Referring to Figure 25 When the door body 20 is continuously opened from the second angle to a third angle, which is less than 90° in this embodiment, the door body 20 drives the first shaft 41 to move relative to the first slot 50 from the third positioning position 53 to a fourth positioning position 54, and the second shaft 42 moves relative to the second slot 60 from the third guide position 63 to a fourth guide position 64, wherein the fourth positioning position 54 is farther away from the side wall 21 than the third positioning position 53, and the fourth guide position 64 is farther away from the front wall 22 and closer to the side wall 21 than the third guide position 63, and the door body 20 moves outward while rotating.

[0179] Referring to Figure 26 When the door body 20 is continuously opened from the third angle to 90°, the door body 20 drives the first shaft 41 to move relative to the first slot 50 from the fourth positioning position 54 to a fifth positioning position 55, and the second shaft 42 moves relative to the second slot 60 from the fourth guide position 64 to a fifth guide position 65, wherein the fifth positioning position 55 is farther away from the side wall 21 than the fourth positioning position 54, and the fifth guide position 65 is closer to the front wall 22 and closer to the side wall 21 than the fourth guide position 64, and the door body 20 moves outward while rotating.

[0180] Referring to Figure 27 When the door body 20 is continuously opened from 90° to a maximum angle, the door body 20 drives the first shaft 41 to move relative to the first slot 50 from the fifth positioning position 55 to a sixth positioning position 56, and the second shaft 42 moves relative to the second slot 60 from the fifth guide position 65 to a sixth guide position 66, wherein the sixth positioning position 55 is farther away from the side wall 21 than the fifth positioning position 54, and the sixth guide position 66 is closer to the front wall 22 and closer to the side wall 21 than the fifth guide position 65.

[0181] In a fourth embodiment of the present application, referring to Figure 28 to Figure 33 Different from the above embodiments, the first slot 50 is arranged on the hinge plate 40, and the first shaft 41 is arranged on the door body 20.

[0182] Since the first slot 50 is arranged on the hinge plate 40 and the second slot 60 is arranged on the door body 20, the first slot 50 and the second slot 60 can intersect on the projection of the top surface of the door body 20, so that the double-slot structure is more compact, and the door body 20 can be made thinner.

[0183] In particular, referring to Figure 28 , the hinge plate 40 can be provided with a first slot 50 with an opening facing the outside, and the door body 20 can be provided with a first shaft 41 extending vertically, the first shaft 41 being adapted to the first slot 50, and one end of the first slot 50 being open to facilitate installation of the hinge assembly. In other embodiments, both ends of the first slot 50 can be closed.

[0184] Referring to Figure 29 , when the door body 20 is opened from the closed state to a first angle, the door body 20 drives the first shaft 41 to move from the first positioning position 51 to the second positioning position 52 relative to the first slot 50, and the second shaft moves from the first guide position 61 to the second guide position 62 relative to the second slot 60, wherein the second positioning position 52 is farther away from the reference plane O than the first positioning position 51, and the second guide position 62 is farther away from the front wall 22 and closer to the side wall 21 than the first guide position 61.

[0185] Since the first shaft 41 moves from the first positioning position 51 to the second positioning position 52 in a direction away from the reference plane O (the inside), the door body 20 moves inward while rotating.

[0186] In other embodiments, the settings at this stage can be the same as the first embodiment, i.e., the second positioning position 52 is closer to the reference plane O than the first positioning position 51, and the second guide position 62 is farther away from the front wall 22 and farther away from the side wall 21 than the first guide position 61, and the door body 20 moves outward while rotating.

[0187] Referring to Figure 30 , when the door body 20 is opened from the first angle to a second angle, the door body 20 drives the first shaft 41 to move from the second positioning position 52 to the third positioning position 53 relative to the first slot 50, and the second shaft 42 moves from the second guide position 62 to the third guide position 63 relative to the second slot 60, wherein the third positioning position 53 is farther away from the reference plane O than the second positioning position 52, and the third guide position 63 is farther away from the front wall 22 and closer to the side wall 21 than the second guide position 62, and the door body 20 moves inward while rotating.

[0188] Referring to Figure 31 , when the door body 20 is opened from the second angle to 90°, the door body 20 drives the first shaft 41 to move from the third positioning position 53 to the fourth positioning position 54 relative to the first slot 50, and the second shaft 42 moves from the third guide position 63 to the fourth guide position 64 relative to the second slot 60, wherein the fourth positioning position 54 is closer to the reference plane O than the third positioning position 53, and the fourth guide position 64 is farther away from the front wall 22 and closer to the side wall 21 than the third guide position 63, and the door body 20 moves outward while rotating.

[0189] Referring to Figure 32When the door body 20 is continuously opened from 90° to a third angle, the door body 20 drives the first shaft 41 to move from the fourth positioning position 54 to a fifth positioning position 55 relative to the first slot 50, and the second shaft 42 moves from the fourth guiding position 64 to a fifth guiding position 65 relative to the second slot 60, wherein the fifth positioning position 55 is closer to the reference plane O than the fourth positioning position 54, and the fifth guiding position 65 is farther away from the front wall 22 and closer to the side wall 21 than the fourth guiding position 64.

[0190] Referring to Figure 33 When the door body 20 is continuously opened from the third angle to a maximum angle, the door body 20 drives the first shaft 41 to move from the fifth positioning position 55 to a sixth positioning position 56 relative to the first slot 50, and the second shaft 42 moves from the fifth guiding position 65 to a sixth guiding position 66 relative to the second slot 60, wherein the sixth positioning position 55 is farther away from the reference plane O than the fifth positioning position 54, and the sixth guiding position 66 is closer to the front wall 22 and closer to the side wall 21 than the fifth guiding position 65.

[0191] In the above movement process, since the first slot 50 is arranged on the hinge plate 40, the position of the first slot 50 remains unchanged, so that the movement trend of the first shaft 51 is always horizontal, and the movement trend of the second shaft 52 relative to the second slot 60 generally has a vertical component, so that the included angle between the movement track of the first shaft 51 in the first slot 50 and the movement track of the second shaft 52 in the second slot 60 is increased, thereby ensuring that the door body 20 does not shake during opening and closing.

[0192] For example, referring to Figure 8 the movement track of the first shaft 41 tends to be vertical, and the included angle between the third guiding track line 634 of the second shaft 42 and the first shaft 41 is not Figure 31 the included angle between the two track lines is large.

[0193] Therefore, in the current embodiment, the movement of the door body 20 is more stable.

[0194] In the embodiment of the present application, the door body 20 rotates around a variable point during opening, and the variable point has a trace, and the trace is (X=(X1+X2) / 2, Y=(Y1+Y2) / 2); wherein X represents the distance of the variable point from the side wall of the door body; Y represents the distance of the variable point from the front wall of the door body. The movement track of the variable point can be calculated by the following formula:

[0195] Referring to Figure 34 When the door body is in a closed state, the distance between the center axis P of the first shaft and the front wall of the door body is a, the distance between the center axis P of the first shaft and the side wall of the door body is b, the distance between the center axes of the first shaft and the second shaft is L, and the included angle between the line connecting the center axes PQ of the first shaft and the second shaft and the front wall of the door body is n.

[0196] Referring toFigure 35 ① When the rotation angle of the door body is m, 0≤m≤n:

[0197] The distance between the central axis P of the first axis and the side wall is X1, X1=b;

[0198] The distance between the central axis P of the first axis and the front wall is Y1, Y1=a;

[0199] The distance between the central axis Q of the second axis and the side wall is X2, X2=b+L*COS(n-m);

[0200] The distance between the central axis Q of the second axis and the front wall is Y2, Y2=a-L*SIN(n-m).

[0201] Referring to Figure 36 ② When the rotation angle of the door body is m, n≤m≤90°+n:

[0202] The distance between the central axis P of the first axis and the side wall is X1, X1=b;

[0203] The distance between the central axis P of the first axis and the front wall is Y1, Y1=a;

[0204] The distance between the central axis Q of the second axis and the side wall is X2, X2=b+L*COS(m-n);

[0205] The distance between the central axis Q of the second axis and the front wall is Y2, Y2=a-L*SIN(m-n).

[0206] Referring to Figure 37 ③ When the rotation angle of the door body is m, 90°+n≤m:

[0207] The distance between the central axis P of the first axis and the side wall is X1, X1=b;

[0208] The distance between the central axis P of the first axis and the front wall is Y1, Y1=a;

[0209] The distance between the central axis Q of the second axis and the side wall is X2, X2=b-L*COS(180°-m+n);

[0210] The distance between the central axis Q of the second axis and the front wall is Y2, Y2=a+L*SIN(180°-m+n).

[0211] ​​​In the above-mentioned hinge assembly 30, the first slot 50 is a horizontal slot whose extension direction is perpendicular to the side wall 21 when the door body is in a closed state. Thus, the horizontal slot occupies less space in the front-rear direction of the door body 20, so that the size of the track slot in the front-rear direction is more compact, and the thickness of the door body 20 can be made thinner. If the door body 20 is thicker, when the door body 20 is opened to 90°, the inner side of the door body 20 will occupy more space in front of the storage compartment, thereby affecting the extraction of the drawer and the like in the storage compartment. Therefore, the design form of the horizontal slot in the present application can reduce the thickness of the door body 20, so that the door body 20 does not interfere with the extraction of the drawer and the like in the storage compartment even if it moves more distance inwardly.

[0212] The design form of the horizontal slot of the first slot 50 in the present application makes the first slot 50 closer to the front wall 22 of the door body 20, and the first shaft 41 moves back and forth in the first slot 50. Thus, the first slot 50 can be set shorter, and the distance by which the corner edge 23 of the track slot structure of the present application exceeds the reference plane O when the door body 20 rotates is smaller than when the first slot is a slant slot in the related art (X Figure 38 Y), so that the door body 20 of the present application needs to move a smaller distance inwardly.

[0213] In addition, the inward offset of the door body 20 is essentially a horizontal displacement of the first shaft 41. In the related art, when the door body is opened and moves inwardly, the displacement of the first shaft relative to the slant slot is decomposed into the horizontal direction to be the inward movement distance of the door body. In the present application, the first shaft 41 moves horizontally, and its actual displacement is the inward movement distance. Therefore, when the first shaft has the same displacement relative to the first slot, the inward movement distance of the door body 20 of the present application is greater, and the inward movement efficiency of the door body 20 is improved.

[0214] In addition, in the related art, the double shafts need to have more actual displacement to achieve the inward movement effect of the present application. The longer the actual displacement, the more serious the wear of the contact movement. The double shafts and double slots require high precision, and the gap caused by wear will make the door body misaligned vertically, thereby causing problems such as jamming and shaking of the door body movement. In the present application, the double shafts actually have smaller displacement during movement, which can effectively reduce wear and increase the service life of the double slots.

[0215] In the related art, the door body 20 has a stationary rotation movement around the first shaft during opening. Thus, before or after the stationary rotation of the door body around the first shaft, the door body has a horizontal displacement, and the door body switches from the rotation offset movement to the rotation movement, which has an obvious change in stress, thereby making the movement prone to jamming.

[0216] Moreover, since the double shafts and double grooves are not always in motion when the door body is opened, there is at least one shaft that stops or starts moving at the moment before or after the rotation motion around one shaft, and the shaft that stops or starts moving will generate acceleration and act force on the groove, causing the groove to wear; the discontinuous motion state will cause poor door opening and closing feeling.

[0217] In the present application, the first shaft 41 and the second shaft 42 are always in motion during the opening process of the door body 20, that is, the position of the first shaft 41 relative to the first groove 50 and the position of the second shaft 42 relative to the second groove 60 always change, and there is no force mutation, and the motion is more smooth. Moreover, the double shaft motion of the present application does not have the mutation of the motion state, and the acceleration change is not generated, so the first groove 50 and the second groove 60 are less likely to wear compared with the related art.

[0218] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
