[0064] Hereinafter, the present application will be described in detail through 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.

[0065] In the description of the present application, it is to be understood by 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, only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0066] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication inside 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.

[0067] In the following, the embodiments of the present application will be described in detail with reference to the drawings.

[0068] In the drawings, the side of the refrigerator facing the user during use is defined as the front side, and the side opposite to it is the rear side.

[0069] Referring to Figure 1 , the refrigerator according to the embodiments of the present application includes a cabinet 1 and a door body 2. The upper and lower ends of the door body 2 are connected to the cabinet 1 through a hinge assembly 3, respectively, so that the cabinet 1 can be opened or closed through the hinge assembly 3.

[0070] Referring to Figures 2 to 6 , the hinge assembly 3 includes a hinge shaft 31 and a hinge groove 32 that cooperate with each other to achieve the opening and closing of the door body 2.

[0071] The hinge assembly 3 includes a hinge plate 33 mounted on the cabinet 1 by means such as screw connection; the hinge plate 33 includes a connecting portion 331 connected to the cabinet 1, and an extension portion 332 extending forward from the connecting portion 331.

[0072] The hinge shaft 31 is arranged on the extension portion 332 and extends vertically. For the hinge assembly 3 at the upper end of the door body 2, the hinge shaft 31 extends downward from the lower surface of the extension portion 332, and for the hinge assembly 3 at the lower end of the door body 2, the hinge shaft 31 extends upward from the upper surface of the extension portion 332.

[0073] The hinge groove 32 is arranged on the door body 2. In the assembled state, the extension portion 332 of the hinge plate 33 is located above the hinge groove 32, and the hinge shaft 31 is inserted into the hinge groove 32.

[0074] It should be noted that the positions of the hinge shaft 31 and the hinge groove 32 can be interchanged, i.e., the hinge shaft 31 is arranged on the door body 2, and the hinge groove 32 is arranged on the hinge plate 33 correspondingly, and the purpose of the present application can still be achieved.

[0075] The refrigerator can include a rotation stopping mechanism 7 arranged between the hinge plate 33 and the door body 2, and the rotation stopping mechanism 7 can achieve the rotation stopping of the door body 2, avoiding the automatic closing of the door body 2 to affect the user's experience.

[0076] With reference to Figures 7 to 9 , the rotation stopping mechanism 7 includes an elastic plunger 71 and a limiting recess 72, and when the elastic plunger 71 is clamped into the limiting recess 72 during the rotation of the door body 2, the door body 2 is rotationally stopped relative to the cabinet 1.

[0077] The elastic plunger 71 can be a ball head plunger type structure, including a support 711, an elastic member 712, and a limiting protrusion 713.

[0078] The support 711 can be a shaft, which is provided with an accommodating cavity with one end opening, and the limiting protrusion 713 is located at the opening end of the accommodating cavity, and the elastic member 712 is located between the cavity bottom of the accommodating cavity and the limiting protrusion 713. The limiting protrusion 713 can be stretched and contracted relative to the support 711 under the action of the elastic member 712, and when the limiting protrusion 713 is stretched out and clamped into the limiting recess 72, the rotation of the door body 2 is stopped.

[0079] Specifically, with reference to Figure 10 , the support 711 can have external threads, thereby facilitating the installation and connection of the elastic plunger 71; the elastic member 712 can be a spring, which has a large elastic range and a long service life.

[0080] The limiting protrusion 713 can be a spherical body, thereby reducing the friction when the limiting protrusion 713 moves in contact with other components. Correspondingly, the limiting recess 72 can be a spherical groove, and the spherical cooperation facilitates the sliding of the limiting protrusion 713 into the limiting recess 72 and the sliding of the limiting protrusion 713 out of the limiting recess 72, thereby increasing the smoothness of the rotation stopping and the continuous rotation of the door body 2.

[0081] The elastic plunger 71 has an extended state and a retracted state. Specifically, Figure 7 , in the retracted state, the limiting protrusion 713 compresses the elastic member 712 and is retracted, and in this state, the limiting protrusion 713 is misaligned with the limiting recess 72; specifically, Figure 8 , in the extended state, the limiting protrusion 713 is extended and clamped into the limiting recess 72.

[0082] Exemplarily, with reference to Figure 7, the elastic plunger 71 is fixed relative to the hinge plate 33, and the limiting recess 72 is arranged on the door body 2. When the elastic plunger 71 is staggered with the limiting recess 72, the rotation opening and closing action of the door body 2 is not affected; referring to Figure 8 When the elastic plunger 71 is opposite to the limiting recess 72, the elastic plunger 71 is clamped into the limiting recess 72, so that the door body 2 is rotated and stopped. When the door body 2 is slightly forced again, the elastic plunger 71 is separated from the limiting recess 72 and changes to a retracted state, and the door body 2 can rotate normally.

[0083] It should be noted that those skilled in the art can understand that the positions of the elastic plunger 71 and the limiting recess 72 can be interchanged, that is, the elastic plunger 71 is arranged on the door body 2, and the limiting recess 72 is correspondingly arranged on the hinge plate 33, and the purpose of the present application can still be achieved.

[0084] The refrigerator of the present application realizes the rotation stopping function of the door body 2 by arranging the rotation stopping mechanism 7 between the hinge plate 33 and the door body 2, and avoids the problem that the door body 2 will be automatically closed under the action of gravity after being opened in the related art.

[0085] In some embodiments of the present application, referring to Figure 11 , Figure 12 The hinge assembly 3 is a single-axis hinge, and under the action of the single-axis hinge 3, the door body 2 only performs a rotating motion relative to the cabinet 1. In this case, the rotation stopping mechanism 7 is arranged separately from the hinge shaft 31 and the hinge groove 32.

[0086] For example, the elastic plunger 71 is fixedly connected to the hinge plate 33, and the limiting recess 72 is arranged on the door body 2:

[0087] The door body 2 is provided with an arc groove 20 with the hinge groove 32 as the center, the limiting recess 72 is arranged in the arc groove 20, and the elastic plunger 71 is inserted into the arc groove 20; when the door body 2 rotates to open and close, the elastic plunger 71 moves relative to the arc groove 20, when the elastic plunger 71 is staggered with the limiting recess 72 in the arc groove 20, the elastic plunger 71 is in a retracted state, and the door body 2 rotates without restriction; when the elastic plunger 71 is opposite to the limiting recess 72 in the arc groove 20, the elastic plunger 71 is in an extended state, the limiting protrusion 713 is clamped into the limiting recess 72, and the door body 2 is rotated and stopped.

[0088] In some embodiments of the present application, referring to Figures 13 to 21 The hinge assembly 3 is a double-axis hinge, and under the action of the double-axis hinge, the door body 2 can move horizontally in the process of rotating to open and close, so that the door body 2 does not touch the cabinet when the refrigerator is embedded in the cabinet. In this case, the rotation stopping mechanism 7 can be combined with the hinge assembly. The rotation stopping mechanism 7 of the present application is suitable for the double-axis hinge structure in the prior art.

[0089] According to an embodiment of the present application, the double shaft hinge has a first hinge part and a second hinge part, the first hinge part comprises a positioning shaft 41 and a positioning groove 50 matched with each other, and the second hinge part comprises a guide shaft 42 and a guide groove 60 matched with each other. The positioning shaft 41 moves in the positioning groove 50, and the guide shaft 42 moves in the guide groove 60, so that the door body 2 can move laterally while rotating.

[0090] As a first embodiment of the position of the rotation-stopping mechanism 7 on the hinge assembly, with reference to FIG. 13, Figure 14 , the rotation-stopping mechanism 7 can be arranged on the first hinge part, i.e. the elastic plunger 71 is arranged on the positioning shaft 41, and the limiting recess 72 is arranged in the positioning groove 50.

[0091] In the double shaft hinge, since the positioning shaft 41 and the positioning groove 50 are matched mainly for orientation, and the guide shaft 42 and the guide groove 60 are matched mainly for guidance, generally, the length of the positioning shaft 41 is greater than that of the guide shaft 42, and the diameter of the positioning shaft 41 is greater than that of the guide shaft 42, which is more conducive to the stability of the door body installation and operation.

[0092] If the positioning shaft 41 is longer, the displacement of the elastic plunger 71 can be set to be relatively large, and the rotation-stopping of the door body 2 under the action of the rotation-stopping mechanism 7 is more stable.

[0093] If the positioning shaft 41 is thicker, the diameter of the elastic plunger 71 can be set to be relatively large, and the area of the limiting convex part 713 matched with the limiting recess 72 is relatively large, and the rotation-stopping of the door body 2 under the action of the rotation-stopping mechanism 7 is more stable.

[0094] As a second embodiment of the position of the rotation-stopping mechanism 7 on the hinge assembly, with reference to FIG. 14, Figure 15 , Figure 16 , the rotation-stopping mechanism 7 can be arranged on the second hinge part, i.e. the elastic plunger 71 is arranged on the guide shaft 42, and the limiting recess 72 is arranged in the guide groove 60.

[0095] In the double shaft hinge, since the positioning shaft 41 and the positioning groove 50 are matched mainly for orientation, and the guide shaft 42 and the guide groove 60 are matched mainly for guidance, generally, the guide groove 60 is longer than the positioning groove 50. Since the guide groove 60 is longer, it is more conducive to arranging the limiting recess 72 at multiple positions in the extension direction of the guide groove 60, for example, the limiting recess 72 can be arranged at positions where the door body 2 is at 0°, 45°, 90°, maximum angle, etc.

[0096] For convenience of description, the position of the hinge shaft 31 in the hinge groove 32 when the door body 2 is in the closed state is defined as the 0° position (as shown in Figure 17In the 0° position of the guide slot 60, the guide shaft 42 is in the 0° position of the guide slot 60, and in the 45° open position of the guide slot 60, the guide shaft 42 is in the 45° open position of the guide slot 60, and so on. In the 0° position of the positioning slot 50, the positioning shaft 41 is in the 0° position of the positioning slot 50, and in the 90° open position of the positioning slot 50, the positioning shaft 41 is in the 90° open position of the positioning slot 50, and so on. Figure 18 In the 0° position of the guide slot 60, the guide shaft 42 is in the 0° position of the guide slot 60, and in the 45° open position of the guide slot 60, the guide shaft 42 is in the 45° open position of the guide slot 60, and so on. In the 0° position of the positioning slot 50, the positioning shaft 41 is in the 0° position of the positioning slot 50, and in the 90° open position of the positioning slot 50, the positioning shaft 41 is in the 90° open position of the positioning slot 50, and so on. Figure 19 In the 0° position of the guide slot 60, the guide shaft 42 is in the 0° position of the guide slot 60, and in the 45° open position of the guide slot 60, the guide shaft 42 is in the 45° open position of the guide slot 60, and so on. In the 0° position of the positioning slot 50, the positioning shaft 41 is in the 0° position of the positioning slot 50, and in the 90° open position of the positioning slot 50, the positioning shaft 41 is in the 90° open position of the positioning slot 50, and so on.

[0097] Because the guide slot 60 is longer, its 0° position, 45° open position, and so on are more dispersed, it is more convenient to set the limiting recesses 72 at multiple positions in the guide slot 60. The positioning slot 50 is shorter, and its various angle positions are more concentrated, which is not conducive to setting the limiting recesses 72 at multiple positions.

[0098] In addition, from the perspective of force, when a person pulls the door, the force is first transmitted to the second hinge part, and the door body 2 is displaced by the second hinge part. Therefore, the rotation stopping mechanism 7 is arranged on the second hinge part, which can produce a better force effect and timely rotation stopping and re-rotation.

[0099] As a third embodiment of the arrangement position of the rotation stopping mechanism 7 on the hinge assembly, referring to Figure 20 , Figure 21 , the rotation stopping mechanism 7 can be arranged on the first hinge part and the second hinge part at the same time. In this embodiment, the advantages of the above two embodiments can be simultaneously achieved: the limiting recesses 72 can be arranged at multiple positions of the guide slot 60 to achieve the rotation stopping of the door body 2 at multiple angles, and the door body 2 is more stably stopped because the relatively thick / long elastic plunger 71 is arranged on the positioning shaft 41.

[0100] In the above embodiments, the elastic plunger 71 is arranged on the hinge shaft 31, and the limiting recess 72 is arranged in the hinge slot 32. When the hinge shaft 31 moves in the hinge slot 32, the elastic plunger 71 moves with the hinge shaft 31. In this process, when the elastic plunger 71 is out of engagement with the limiting recess 72, the rotation stopping mechanism 7 does not affect the movement of the door body 2. When the door body 2 moves to the position where the elastic plunger 71 is opposite to the limiting recess 72, the limiting protrusion 713 is clamped into the limiting recess 72. At this time, if there is no external force acting on the door body 2, the door body 2 will be stopped under the limiting action of the elastic plunger 71 and the limiting recess 72. If there is an external force acting on the door body 2, the force of the door body 2 continuing to move will overcome the resistance of the elastic plunger 71, so that the limiting protrusion 713 of the elastic plunger 71 is compressed by the elastic member 712 and retracted, without affecting the continuous movement of the door body 2.

[0101] The first embodiment of the connecting mode of the elastic plunger 71 on the hinge shaft 31 is as follows:

[0102] Referring to Figure 22 , the hinge shaft 31 is provided with a mounting hole 310, and the elastic plunger 71 is mounted in the mounting hole 310.

[0103] Specifically, one end of the mounting hole 310 is open, and the open end faces the groove bottom of the hinge groove 32. Correspondingly, the groove bottom of the hinge groove 32 is provided with a limiting recess 72.

[0104] In the embodiments of the present application, the rotation-stopping mechanism 7 can be arranged on the hinge assembly 3 at the upper end of the door body 2 and / or on the hinge assembly 3 at the lower end of the door body 2.

[0105] For the rotation-stopping mechanism 7 arranged on the hinge assembly 3 at the upper end of the door body 2, the mounting hole 310 is open downward on the hinge shaft 31, and the groove bottom of the hinge groove 32 is the bottom surface of the hinge groove 32. The elastic plunger 71 can be mounted in the mounting hole 310 in the form of threaded connection, so that the limiting protrusion 713 of the elastic plunger 71 is located at the bottom end of the hinge shaft 31. During the movement of the hinge shaft 31 relative to the hinge groove 32, the limiting protrusion 713 is compressed upward by the elastic member 712 due to the stop of the groove bottom of the hinge groove 32. When the hinge shaft 31 moves to the position of the limiting recess 72, the limiting protrusion 713 is popped out under the action of the elastic force of the elastic member 712 due to the lowered position of the limiting recess 72 on the hinge groove, so that the limiting protrusion 713 enters the limiting recess 72 and is in the extended state.

[0106] For the rotation-stopping mechanism 7 arranged on the hinge assembly 3 at the lower end of the door body 2, the mounting hole 310 is open upward on the hinge shaft 31, and the groove bottom of the hinge groove 32 is the top surface of the hinge groove 32. The limiting protrusion 713 of the elastic plunger 71 is located at the top end of the hinge shaft 31. During the movement of the hinge shaft 31 relative to the hinge groove 32, the limiting protrusion 713 is compressed downward by the elastic member 712 due to the action of the gravity of the door body 2.

[0107] In the case that the elastic plunger 71 is in the extended state and the elastic member 712 is in the natural state, when the rotation-stopping mechanism 7 is arranged on the hinge assembly at the upper end of the door body 2, there may be a phenomenon that the elastic plunger 71 does not completely enter the limiting recess 72 due to assembly errors, so that the elastic plunger 71 is easily separated from the limiting recess 72 and the door body 2 is not stable in rotation. In the present application, the elastic member 712 is still in the compressed state when the elastic plunger 71 is in the extended state, so that the elastic member 712 can push the limiting protrusion 713 to enter the limiting recess 72, thereby increasing the stability of the cooperation between the two.

[0108] When the rotation-stopping mechanism 7 is arranged at the hinge assembly 3 at the lower end of the door body 2, the elastic plunger 71 is subjected to the gravity of the door body 2, and the force during movement is stable, which can ensure the stability of the limiting protrusion 713 being clamped into the limiting recess 72, and the door body 2 is more stably rotated and stopped.

[0109] According to some embodiments of the present application, the elastic plunger 71 can be installed perpendicularly to the axis of the hinge shaft 31, that is, the limiting protrusion 713 is located at the side wall of the hinge shaft 31, and the extension direction is perpendicular to the axis of the hinge shaft 31; correspondingly, the limiting recess 72 is arranged on the side wall of the hinge groove 32, and the purpose of the present application can also be achieved.

[0110] The second embodiment of the connection mode of the elastic plunger 71 on the hinge shaft 31 is as follows:

[0111] Different from the above embodiments, referring to Figure 23 , the hinge shaft 31 can simultaneously serve as the support 711 of the elastic plunger 71, and the elastic member 712 and the limiting protrusion 713 are directly installed on the hinge shaft 31. In this way, the structure of the support 41 can be omitted, the structure at the hinge shaft 31 is simplified, and the product cost is reduced.

[0112] According to some embodiments of the present application, referring to Figure 24 , in general, in order to facilitate the installation of the door body 2, a certain gap is usually reserved between the door body 2 and the upper and lower hinge plates in the vertical direction. Due to the gravity of the door body 2 itself, the door body 2 will be in contact with the hinge plate 33 at the lower end, and a gap H1 will be generated between the door body 2 and the hinge plate 33 at the upper end, that is, there is a gap H1 between the top of the hinge groove 32 and the hinge plate 33.

[0113] When the refrigerator is dropped during transportation, the door body 2 will move upward and impact the hinge plate 33 at the upper end. In order to avoid this situation, in the embodiments of the present application, the limiting recess 72 of the rotation-stopping mechanism 7 is arranged at the 0° position of the hinge groove 32, and the upper limit distance of the limiting protrusion 713 is H2, H2

[0114] According to the embodiment of the present application, when the limiting protrusion 713 is in the retracted state, the elastic member 712 can be in the extreme compression state, and the limiting protrusion 713 exposes the opening end of the supporting member 711. In this way, on the one hand, when the door body 2 presses the limiting protrusion 713 upward, the limiting protrusion 713 will not retract into the inside of the supporting member 711 to cause the impact of the door body on the hinge shaft 31, and on the other hand, the limiting protrusion 713 is always exposed to the supporting member 711 to ensure that it is always in rolling contact with the hinge groove 32, which reduces the moving friction when the hinge shaft 31 contacts the hinge groove 32, and the rolling movement increases the smoothness of the activity of the hinge assembly 3 when the door body 2 is opened and closed.

[0115] The design of the double-shaft hinge is mainly to meet the requirement of the refrigerator embedded in the cabinet. In general, the double-shaft hinge structure can prevent the door body 2 from touching the cabinet during the opening and closing of at least 90°. In some refrigerators with a double-shaft hinge, the door body 2 will not touch the cabinet even when it is opened to more than 90°. Therefore, when the refrigerator is embedded in the cabinet, it has a maximum opening angle of about 90°, and the position of the hinge shaft 31 in the hinge groove 32 when the refrigerator is embedded in the cabinet and the door body 2 is opened to the maximum opening angle is defined as the maximum embedded opening position (for example, the position of the limiting protrusion 713 in the limiting recess 72 in the maximum embedded opening position is 70d in FIG. 7). Figure 25

[0116] In some embodiments of the present application, in order to prevent the refrigerator from colliding with the cabinet due to the inertia when the door body 2 is opened to the maximum embedded opening position, the limiting recess 72 is arranged at the maximum embedded opening position of the hinge groove 32, so that when the door body 2 is opened to the maximum embedded opening position, the door body 2 is rotated and stopped at the maximum embedded opening position due to the clamping of the elastic plunger 71 into the limiting recess 72, effectively preventing the door body 2 from colliding with the cabinet. In this embodiment, the rotation stopping mechanism 7 can be arranged on both the first hinge member and the second hinge member, and the rotation stopping mechanisms 7 at the two positions work together to increase the reliability of the rotation and stopping of the door body 2 at the maximum embedded opening position. However, in other embodiments, the rotation stopping mechanism 7 can be arranged only on the first hinge member or the second hinge member.

[0117] The following describes several double-shaft movement trajectories:

[0118] First movement trajectory

[0119] Referring to Figure 26 , Figure 27 , the positioning groove 50 extends in a direction parallel to the front surface of the cabinet 1 when the door body 2 is in the closed state.

[0120] <First stage> Referring to Figure 28 ​When the door body 2 is opened from the closed state to the first angle, the positioning shaft 41 moves from the first positioning position 51 to the second positioning position 52 relative to the positioning groove 50, and the guide shaft 42 moves from the first guide position 61 to the second guide position 62 relative to the guide groove 60. 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. It should be noted that the side of the door body 2 close to the hinge assembly when the door body 2 is in the closed state is the side wall 21, the front surface of the door body 2 is the front wall 22, and the intersection of the side wall 21 and the front wall 22 is the corner 23.

[0121] Since the positioning shaft 41 moves from the first positioning position 51 to the second positioning position 52 in a direction away from the side wall 21 (the inner side), it is equivalent to the positioning groove 50 moving outward for the door body 2. Therefore, in the first stage of the embodiment, the door body 2 moves outward when it is just opened. It should be noted that the plane on which the side of the cabinet 1 close to the hinge assembly is defined as the reference plane O, and the side of the cabinet on one side of the reference plane O is the inner side, and the other side is the outer side.

[0122] 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 Figure 26 In this 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 2 moves slightly outward. Since the corner 23 of the door body 2 just exceeds the reference plane O when it is just opened, even if the door body 2 moves slightly outward, it will not interfere with the cabinet.

[0123] In this stage, the door body 2 is arranged to move slightly outward, and the first guide trajectory line 612 extends in a direction away from the front wall 22 and away from the side wall 21, so that the transition point between the first guide trajectory line 612 and the second guide trajectory line 623 in the second stage is relatively smooth, improving the smoothness of the movement of the door body 2.

[0124] In addition, the extension of the first guide trajectory line 612 in a direction 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 positioning shaft 41, ensuring that the door body 2 does not shake during movement.

[0125] In other embodiments, the second positioning position 52 can be closer to the side wall 21 than the first positioning position 51, and the second guide position 62 can be farther away from the front wall and closer to the side wall 21 than the first guide position 61. In this way, the door body 2 moves inward when it is just opened.

[0126] <Second stage> refer to Figure 29When the door body 2 continues to open from the first angle to the second angle, the positioning shaft 41 moves from the second positioning position 52 to the third positioning position 53 relative to the positioning groove 50, and the guide shaft 42 moves from the second guide position 62 to the third guide position 63 relative to the guide groove 60. The third positioning position 53 is closer to the side wall 21 than the second positioning position 52 (and the first positioning position 51); 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.

[0127] Since the positioning shaft 41 moves from the second positioning position 52 to the third positioning position 53 in a direction close to the side wall 21 (the outer side), it is equivalent to the door body 2 moving the positioning groove 50 inward. Therefore, in the second stage of the embodiment, the door body 2 moves inward by a distance while rotating, so that the corner edge 23 moves inward relative to the reference plane O, avoiding collision of the corner edge 23 with the cabinet 100.

[0128] In some embodiments of the present application, the distance of lateral movement of the door body 2 per unit angle of rotation in the first stage is μ1, and the distance of lateral movement of the door body 2 per unit angle of rotation in the second stage is μ2, μ1<μ2, that is, the lateral movement in the first stage when the door body 2 is just opened is relatively small, which can avoid the lateral friction between the door seal on the rear surface of the door body 2 and the front surface of the cabinet 1 caused by the large lateral movement distance per unit angle of rotation when the door body 2 is just opened. In addition, if the lateral movement distance per unit angle of rotation when the door body 2 is just opened is large, it will affect the hand feeling and fluency of opening the door, so the lateral movement distance can be set to be small when the door body 2 is just opened.

[0129] Specifically, the slope of the first guide trajectory line 612 can be greater than the slope of the second guide trajectory line 623 (the slopes described herein are absolute values). The greater the slope, the smaller the distance of lateral movement per unit angle of rotation of the door body.

[0130] If the door body 2 moves inward in both the first stage and the second stage, since the curvature of the movement trajectory lines of the guide shafts in the two stages needs to change, it is possible that a sharp point will be generated at the connection between the first guide trajectory line 612 and the second guide trajectory line 623, affecting the hand feeling of opening the door, so the lateral movement of the door body 2 to the outer side is set in the first stage, which can make the connection between the first guide trajectory line 612 and the second guide trajectory line 623 slightly smoother.

[0131] In some embodiments of the present application, the angle between the second guide trajectory line 623 and the movement trajectory line of the positioning shaft 41 is >45°, which can avoid the problem of shaking when the movement trends of the two shafts are close to parallel, ensuring that the door body 2 does not shake during movement.

[0132] <Third stage> with reference to Figure 30When the door body continues to open from the second angle to a 90° state, the positioning shaft 41 moves from the third positioning position 53 to a fourth positioning position 54, and the guide shaft 42 moves from the third guide position 63 to a fourth guide position 64. The fourth positioning position 54 is farther away from the side wall 21 than the third positioning position 53; 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.

[0133] Since the positioning shaft 41 moves from the third positioning position 53 to the fourth positioning position 54 in a direction away from the side wall 21 (the inner side), it is equivalent to the door body 2 moving the positioning groove 50 to the outer side. Therefore, in the third stage, the door body 2 moves to the outer side while rotating to open.

[0134] The door body 2 has passed the dangerous period of interference with the cabinet in the second stage, so in this stage, the door body 2 will not touch the cabinet even if it moves to the outer side. Moreover, moving to the outer side can also reduce the obstruction of the door body 2 to the storage compartment, thereby avoiding the restriction of the door body 2 to the drawer in the storage compartment.

[0135] In some embodiments, the front wall 22 of the door body 2 can be flush with the reference plane O when the door body 2 is in the 90° open state, which can minimize the space occupied by the door body 2 in front of the storage compartment, thereby avoiding the influence of the door body 2 on the drawer in the storage compartment.

[0136] In other embodiments, when the door body 2 is in the 90° open state, the door body 2 as a whole is located on the inner side of the reference plane O, i.e., the front wall 22 of the door body 2 has a gap to the reference plane O, so that even if the door body 2 continues to open by 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.

[0137] <Fourth stage> refer to Figure 31 When the door body continues to open from 90° to a third angle state, the positioning shaft 41 moves from the fourth positioning position 54 to a fifth positioning position 55, and the guide shaft 42 moves from the fourth guide position 64 to a fifth guide position 65. The fifth positioning position 55 is farther away from the side wall 21 than the fourth positioning position 54; the fifth guide position 65 is farther away from the front wall 22 and closer to the side wall 21 than the fourth guide position 64, and the door body 2 moves to the upper left. The third angle is the maximum angle that the door body 2 can be opened when the refrigerator is embedded in the cabinet.

[0138] <Fifth stage> refer to Figure 32When the door body 2 is continuously opened from the third angle to the maximum angle, the positioning shaft 41 moves from the fifth positioning position 55 to the sixth positioning position 56, the guide shaft 42 moves from the fifth guide position 65 to the sixth guide position 66, the sixth positioning position 56 is farther away from the side wall 21 than the fifth positioning position 55, 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, and the door body 2 moves upward and to the left.

[0139] The second movement trajectory

[0140] Reference Figure 33 Different from the above embodiment, the positioning groove 50 includes two first and second groove sections 501 and 502 extending in different directions. In the direction from the inner side to the outer side, the first groove section 501 extends toward the side wall 21, and the second groove section 502 is connected to the end of the first groove section 501 and extends toward the front wall 22 and the side wall 21. The guide groove 60 is generally a curved groove extending away from the front wall 22 and toward the side wall 21. In other embodiments, the rear part of the positioning groove 50 can also be in the form of a straight groove, and part or all of the guide groove 60 can also be in the form of a straight groove.

[0141] <First stage> Reference Figure 34 When the door body 2 is opened from the closed state to the first angle, the guide shaft 42 moves from the first guide position 61 to the second guide position 62, and under the guidance, the positioning shaft 41 moves from the first positioning position 51 to the second positioning position 52, 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 61, so that the door body 2 moves inward by a first distance while rotating.

[0142] <Second stage> Reference Figure 35 When the door body 2 is continuously opened from the first angle to the second angle, the positioning shaft 41 moves from the second positioning position 52 to the third positioning position 53, and at the same time, the guide shaft 42 moves from the second guide position 62 to the third guide position 63, 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 closer to the side wall 21 and farther away from the front wall 22 than the second guide position 62, so that the door body 2 moves inward by a second distance while rotating, and the door body 2 continues to move inward, so that the corner edge 23 moves inward relative to the reference plane O, avoiding collision of the corner edge 23 with the cabinet 100.

[0143] In the first stage, the movement trajectory of the guide shaft 42 relative to the guide groove 60 is a first guide trajectory line 612; in the second stage, the movement trajectory of the guide shaft 42 relative to the guide groove 60 is a second guide trajectory line 623.

[0144] The connection of the first guide track line 612 and the second guide track line 623 has a trend change point, so that the inward moving distance d of the door body 2 in a unit opening angle is different in the first stage and the second stage, and the inward moving distance d of the unit angle in the first stage is slightly smaller than that in the second stage.

[0145] Specifically, the distance of the door body 2 rotating a unit angle to move inward in the first stage is μ1, and the distance of the door body 2 rotating a unit angle to move inward in the second stage is μ2, μ1<μ2, that is, the amplitude of the door body 2 moving inward in the first stage when the door body 2 is just opened is relatively small, so that the transverse friction between the door seal of the rear surface of the door body 2 and the front surface of the cabinet 1 caused by the large unit angle inward moving distance when the door body 2 is just opened can be avoided.

[0146] <Third stage> refer to Figure 36 When the door body 2 is continuously opened from the second angle to 90°, the positioning shaft 41 moves from the third positioning position 53 to the fourth positioning position 54, and the guide shaft 42 moves from the third guide position 63 to the fourth guide position 64, the fourth positioning position 54 is closer to the side wall 21 and the front wall 22 than the third positioning position 53, and the fourth guide position 64 is closer to the side wall 21 and farther away from the front wall 22 than the third guide position 63, so that the door body 2 moves inward by a third distance while rotating, and the door body 2 continues to move inward.

[0147] The door body 2 always moves inward from the closed state to the 90° opening state, so that the door body 2 is located on the inner side of the reference plane O at 90°, so that the door body 2 can continue to open to >90° before colliding with the cabinet, increasing the opening angle of the door body when the refrigerator is placed in the cabinet for use, and facilitating the user to take and place food.

[0148] <Fourth stage> refer to Figure 37 When the door body 2 is continuously opened from 90° to a third angle, the positioning shaft 41 moves from the fourth positioning position 54 to the fifth positioning position 55, and the guide shaft 42 moves from the fourth guide position 64 to the fifth guide position 65. The fifth positioning position 55 is closer to the side wall 21 and the front wall 22 than the fourth positioning position 54, and the fifth guide position 65 is closer to the side wall 21 and farther away from the front wall 22 than the fourth guide position 64.

[0149] In this stage, the third angle is slightly larger than 90°, about 105°. The door body 2 can continue to open to the third angle without colliding with the cabinet.

[0150] <Fifth stage> refer to Figure 38When the door body 2 is continuously opened from the third angle to the maximum angle, the guide shaft 42 moves from the fifth guide position 65 to the sixth guide position 66, so that the positioning shaft 41 moves from the fifth positioning position 55 to the sixth positioning position 56. The sixth positioning position 56 is located between the fifth positioning position 55 and the third positioning position 53; the sixth guide position 66 is farther away from the front wall 22 and closer to the side wall 21 than the fifth guide position 65.

[0151] When the door body 2 is opened more than 90°, the corner edge 23 of the door body 2 has been located on the inner side of the reference plane O, and the positioning shaft 41 moves in the direction away from the front wall 22 and the side wall 21, which is equivalent to that the door body 2 drives the positioning groove 50 to move in the direction close to the reference plane O, i.e. the corner edge 23 of the door body 2 moves to the outer side, which can avoid the problem that the door body 2 continues to move to the inner side and occupies the space in front of the storage compartment, thereby causing the drawer in the storage compartment to be blocked by the door body 2 and unable to be pulled out.

[0152] The third movement track

[0153] Reference Figure 39 The difference from the second movement track is that the end of the guide groove 60 is bent forward, i.e. the sixth guide position 66 is closer to the front wall than the fifth guide position 65, so that the positioning shaft 41 does not retreat in the positioning groove 50.

[0154] Since the first stage to the fourth stage of the embodiment are basically the same as the trend of the second movement track, they will not be repeated here.

[0155] <the fifth stage> Reference Figure 40 When the door body 2 is continuously opened from the third angle to the maximum angle, the positioning shaft 41 moves from the fifth positioning position 55 to the sixth positioning position 56; and the guide shaft 42 moves from the fifth guide position 65 to the sixth guide position 66. The sixth positioning position 506 is closer to the side wall 21 and closer to the front wall 22 than the fifth positioning position 55; and the sixth guide position 606 is closer to the side wall 21 and closer to the front wall 22 than the fifth guide position 65.

[0156] The fourth movement track

[0157] The difference from the second and third movement tracks is that reference Figure 41 When the door body 2 is in the closed state, the positioning groove 50 further includes a third groove segment 503 connected to the inner side of the first groove segment 501, i.e. the positioning groove 50 generally includes the third groove segment 503 on the inner side, the first groove segment 501 in the middle part and the second groove segment 502 on the outer side. Corresponding to the change of the shape of the inner side of the positioning groove 50, the door body 2 is different from the above two embodiments in the initial opening stage, and the same parts as the third stage to the fifth stage in the above track will not be introduced again.

[0158] <the first stage> Reference Figure 42When the door body 2 is opened from the closed state to the first angle, the positioning shaft 41 moves from the seventh positioning position 57 to the eighth positioning position 58, and the guide shaft 42 moves from the seventh guide position 67 to the eighth guide position 68. The eighth positioning position 58 is closer to the side wall 21 and farther from the front wall 22 than the seventh positioning position 57, and the eighth guide position 68 is farther from the front wall 22 and closer to the side wall 21 than the seventh guide position 67. The positioning shaft 41 moves towards the side wall 21 (the outer side) and away from the front wall 22 (the rear side), that is, the positioning groove 50 moves towards the inner side and the front side relative to the positioning shaft 41, so that the door body 2 moves a distance towards the inner side and the front side while rotating; the door body 2 moves towards the inner side, that is, the corner edge 23 is moved towards the inner side to avoid collision with the cabinet 100; the door body 2 moves towards the front side to avoid friction between the door seal on the door body 2 and the front surface of the cabinet 1.

[0159] <Second stage> refer to Figure 43 When the door body 2 is opened from the first angle to the second angle, wherein the first angle < the second angle < 90°, the positioning shaft 41 moves from the eighth positioning position 58 to the third positioning position 53, and the guide shaft 42 moves from the eighth guide position 68 to the seventh guide position 67; the third positioning position 53 is closer to the side wall 21 than the eighth positioning position 58, and the line between the third positioning position 53 and the eighth positioning position 58 is parallel to the front surface of the cabinet 1 when the door body 2 is in the closed state, and the third guide position 63 is closer to the side wall 21 and farther from the front wall 22 than the eighth guide position 68, so that the door body 2 moves a distance towards the inner side while rotating, and the door body 2 continues to move towards the inner side, so that the corner edge 23 moves towards the inner side relative to the reference plane O, avoiding collision with the cabinet 100.

[0160] Fifth trajectory

[0161] Refer to Figure 44 The positioning groove 50 and the guide groove 60 are both curved grooves.

[0162] <First stage> refer to Figure 45When the door body 2 is opened from the closed state to the first state, the positioning shaft 41 moves from the first positioning position 51 to the second positioning position 52 relative to the positioning groove 50; at the same time, the guide shaft 42 moves from the first guide position 61 to the second guide position 62 relative to the guide groove 60. The second positioning position 52 is farther away from the front wall 22 and 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, so that the positioning shaft 41 moves in the direction of being closer to the side wall 21 and farther away from the front wall 22, which is equivalent to that the door body 2 with the positioning groove 50 moves a first distance away from the side wall 21 (the inner side) and a distance closer to the front wall 22 (the front side), and the door body 2 moves inward to avoid the side edge 33 from protruding too much from the side of the cabinet 1 to touch the cabinet; since the right rear end of the door body 2 will rotate backward relative to the positioning shaft 41 when the door body 2 is just opened, and as the door body 2 moves inward, the door seal on the door body 2 will be in contact and friction with the front side of the cabinet 1, and in the present application, the door body 2 is arranged to move toward the front side, which can avoid the friction between the door seal and the front side of the cabinet 1, and improve the service life of the door seal.

[0163] <Second stage> refer to Figure 46 When the door body 2 is continuously opened from the first state to the second state, the second state is less than 90°, the positioning shaft 41 moves from the second positioning position 52 to the third positioning position 53 relative to the positioning groove 50, and the guide shaft 42 moves from the second guide position 62 to the third guide position 63 relative to the guide groove 60. Among them, the third positioning position 53 is closer to the front wall 22 and 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, so that the door body 2 moves inward by a second distance.

[0164] <Third stage> refer to Figure 47 When the door body 2 is continuously opened from the second state to 90°, the door body 2 only performs a rotating motion, the position of the positioning shaft 41 in the positioning groove 50 does not change, and the door body 2 rotates around the positioning shaft 41 as the center, and the guide shaft 42 moves along a circular arc in the guide groove 60 to the fourth guide position 64.

[0165] <Fourth stage> refer to Figure 48 When the door body 2 is continuously opened from 90°, the positioning shaft 41 moves from the third positioning position 53 to the fourth positioning position 54 relative to the positioning groove 50, and the guide shaft 42 moves from the fourth guide position 64 to the fifth guide position 65 relative to the guide groove 60. Among them, the fourth positioning position 54 is closer to the front wall 22 and the side wall 21 than the third positioning position 53, and the fifth guide position 65 is closer to the front wall 22 and the side wall 21 than the fourth guide position 64.

[0166] It should be noted that in the above description of the several movement trajectories, "first angle", "second angle", and the like are only used to distinguish the change of the opening angle of the door body 2 in each movement trajectory; "first positioning position", "second positioning position", and the like are only used to distinguish the change of the position of the positioning shaft 41 relative to the positioning groove 50 in each movement trajectory; "first guide position", "second guide position", and the like are only used to distinguish the change of the position of the guide shaft 42 relative to the guide groove 50 in each movement trajectory; the same code "first angle", "first positioning position", "first guide position", and the like in different movement trajectories can not be the same. For example, the first angle in the first movement trajectory and the first angle in the second movement trajectory can not be the same.

[0167] The above several movement trajectories are only partial embodiments of the double-axis hinge, and the rotation-stopping mechanism 7 of the present application can be applied to all forms of double-axis hinge structures.

[0168] In some embodiments, the rotation-stopping mechanism 7 can be arranged at the closed position of the door body 2.

[0169] Specifically, the elastic plunger 71 of the rotation-stopping mechanism 7 can be arranged on the positioning shaft 41, and the limiting recess 72 is arranged at the 0° position of the positioning groove 50; or / and, the elastic plunger 71 can be arranged on the guide shaft 42, and the limiting recess 72 is arranged at the 0° position of the guide groove 60.

[0170] In combination with specific trajectories, in the first movement trajectory, the second movement trajectory, the third movement trajectory, and the fifth movement trajectory, when the door body 2 is closed, the positioning shaft 41 is located at the first positioning position 51 of the positioning groove 50; and the guide shaft 42 is located at the first guide position 61 of the guide groove 60. The first positioning position 51 is the 0° position of the positioning groove 50, and the first guide position 61 is the 0° position of the guide groove 60. Therefore, the limiting recess 72 is arranged at the first positioning position 51 and / or the first guide position 61.

[0171] In the fourth movement trajectory, when the door body 2 is closed, the positioning shaft 41 is located at the seventh positioning position 57 of the positioning groove 50; and the guide shaft 42 is located at the seventh guide position 57 of the guide groove 60. The seventh positioning position 57 is the 0° position of the positioning groove 50, and the seventh guide position 57 is the 0° position of the guide groove 60. Therefore, the limiting recess 72 is arranged at the seventh positioning position 57 and / or the seventh guide position 57.

[0172] Arranging the rotation-stopping mechanism 7 at the closed position of the door body 2 can assist in closing the door body 2 and avoid the phenomenon that the door body 2 is not closed to the position and is opened. In addition, under the limitation (H2

[0173] In some embodiments, the rotation-stopping mechanism 7 can be arranged at the 90° opening position of the door body 2.

[0174] Specifically, the elastic plunger 71 is arranged on the positioning shaft 41, and the limiting recess 72 is arranged at the 90° opening position of the positioning groove 50; or / and, the elastic plunger 71 is arranged on the guide shaft 42, and the limiting recess 72 is arranged at the 90° opening position of the guide groove 60.

[0175] In the above several movement trajectories, when the door body 2 is at the 90° position, the positioning shaft 41 is located at the fourth positioning position 54, and the guide shaft 42 is located at the fourth guide position 64. The fourth positioning position 54 is the 90° opening position of the positioning groove 50, and the fourth guide position 64 is the 90° opening position of the guide groove 60. Therefore, the limiting recess 72 can be arranged at the fourth positioning position 54 and / or the fourth guide position 64.

[0176] The rotation-stopping mechanism 7 is arranged at the 90° opening position of the door body 2, so that the door body 2 can be stopped at 90°, avoiding the automatic closing of the door body 2 affecting the user to take or place food, and also avoiding the continued opening of the door body 2 colliding with the cabinet.

[0177] In some embodiments, the rotation-stopping mechanism 7 can be arranged at the maximum angle position of the door body 2 that can be opened when the refrigerator is embedded in the cabinet.

[0178] Specifically, the elastic plunger 71 is arranged on the positioning shaft 41, and the limiting recess 72 is arranged at the maximum embedded opening position of the positioning groove 50; or / and, the elastic plunger 71 is arranged on the guide shaft 42, and the limiting recess 72 is arranged at the maximum embedded opening position of the guide groove 60.

[0179] In the first four movement trajectories, when the door body 2 is at the third angle opening state, the positioning shaft 41 is located at the fifth positioning position 55, and the guide shaft 42 is located at the fifth guide position 65. The fifth positioning position 55 is the maximum embedded opening position of the positioning groove 50, and the fifth guide position 65 is the maximum embedded opening position of the guide groove 60. Therefore, the limiting recess 72 can be arranged at the fifth positioning position 55 and / or the fifth guide position 65.

[0180] The rotation-stopping mechanism 7 is arranged at the third angle position of the door body 2, so that the door body 2 can be stopped at the third angle position, avoiding the automatic closing of the door body 2 affecting the user to take or place food, and also avoiding the continued opening of the door body 2 colliding with the cabinet.

[0181] In some embodiments, the rotation-stopping mechanism 7 can be arranged at the maximum angle position of the door body 2 (not embedded in the cabinet for use).

[0182] In the first four movement trajectories, when the door body 2 is at the maximum opening angle in the normal use state, the positioning shaft 41 is located at the sixth positioning position 56, and the guide shaft 42 is located at the sixth guide position 66. The sixth positioning position 56 is the maximum normal opening position of the positioning groove 50, and the sixth guide position 66 is the maximum normal opening position of the guide groove 60. Therefore, the limiting recess 72 can be arranged at the sixth positioning position 56 and / or the sixth guide position 66.

[0183] In the fifth movement trajectory, when the door body 2 is at the maximum opening angle in the normal use state, the positioning shaft 41 is located at the fourth positioning position 54, and the guide shaft 42 is located at the fifth guide position 65. Therefore, the limiting recess 72 can be arranged at the fourth positioning position 54 and / or the fifth guide position 65.

[0184] The rotation stopping mechanism 7 is arranged at the maximum angle position of the door body 2, so that the door body 2 can be stopped at the maximum angle position, avoiding the influence of the automatic closing of the door body 2 on the user taking and placing food, and assisting in limiting the maximum opening position of the door body 2.

[0185] In some embodiments, the rotation stopping mechanism 7 can be arranged at the transition point of the hinge assembly 3. The transition point is the position point at which the movement trend direction of the hinge shaft 31 in the hinge groove 32 changes. That is, the connection between the two groove segments in the hinge groove 32, for example, the connection between the first groove segment 501 and the second groove segment 502 of the positioning groove 50 in the second and third movement trajectories, the connection between the first groove segment 501 and the second groove segment 502 of the positioning groove 50 in the fourth movement trajectory, and the connection between the third groove segment 503 and the first groove segment 501 of the positioning groove 50 in the fourth movement trajectory are all transition points, and the movement trend direction of the hinge shaft 31 will change when it moves to these transition points.

[0186] After the upper and lower hinge assemblies of the door body 2 are assembled, assembly errors will inevitably exist, which may cause the door body 2 to be stuck and cause wear of the hinge groove 32. Therefore, an installation gap is usually reserved between the hinge shaft 31 and the hinge groove 32 to avoid the problems of the door body 2 being stuck and the hinge groove 32 being worn due to assembly errors.

[0187] Generally, the gap between the guide shaft 42 and the guide groove 60 is 0.1-0.2 mm, and the gap between the positioning shaft 41 and the positioning groove 50 is 0-0.1 mm. When the hinge shaft 31 moves to the transition point of the hinge groove 32, the movement curve trend changes at this time and a round corner appears in the transition part, and the door body 2 will shake at this position, affecting the opening door feel.

[0188] Therefore, the rotation stopping mechanism 7 is arranged at the transition point of the hinge groove 32, so that the door body 2 is stopped at the transition point, which can reduce the poor opening door feel caused by the shaking of the door body 2.

[0189] Specifically, the rotation-stopping plunger 71 of the rotation-stopping mechanism 7 is arranged on the positioning shaft 41, and the limiting recess 72 is arranged at the transition point of the positioning groove 50.

[0190] In some embodiments, the rotation-stopping mechanism 7 can be arranged at the speed mutation point of the hinge assembly 3. The speed mutation point is a position point at which the speed of the hinge shaft 31 moving in the hinge groove 32 is suddenly changed. For example, in the fifth movement trajectory, when the door body 2 is opened from the first state to the second state, the door body 2 rotates and moves laterally; when the door body 2 is continuously opened from the second state to 90°, the door body 2 only rotates and no longer moves laterally; when the door body 2 is continuously opened from 90°, the door body 2 rotates and moves laterally again. That is, the door body 2 rotates and moves laterally in the movement process, suddenly stops and only rotates around the positioning shaft, and then changes to rotate and move laterally again, and the movement speed is suddenly changed twice. Correspondingly, the movement speed of the positioning shaft 41 is suddenly changed at the third positioning position 53 of the positioning groove 50, and the third positioning position 53 is the speed mutation point.

[0191] In the process of changing the movement of the positioning shaft 41 from static to dynamic and the process of changing the movement from dynamic to static (herein only the lateral movement of the positioning shaft 41 is described), the movement speed of the positioning shaft 41 is suddenly changed to 0, the speed change will generate acceleration, and the acceleration will generate force. The force generated by the acceleration is borne by the side wall of the positioning groove 50 to offset, causing the wear of the positioning shaft 41 and the positioning groove 50, and the increase of the wear gap after long-term use will cause the door body 2 to shake at the speed mutation point or even be stuck in movement.

[0192] Therefore, the embodiments of the present application arrange the rotation-stopping mechanism 7 at the speed mutation point, so that the force generated by the speed mutation is resisted by the rotation-stopping mechanism 7, thereby reducing the force borne by the positioning shaft 41 and the positioning groove 50; at the same time, since the position of the positioning shaft 41 is unchanged, the limiting convex part 713 and the limiting recess 72 resist the speed mutation force, and the stability of the rotation movement is also increased.

[0193] Specifically, the rotation-stopping plunger 71 of the rotation-stopping mechanism 7 is arranged on the positioning shaft 41, and the limiting recess 72 is arranged at the third positioning position 53 (the speed mutation point) of the positioning groove 50.

[0194] According to the present application, by arranging the rotation-stopping mechanism 7 between the door body 1 and the cabinet 1, when the elastic plunger 71 of the rotation-stopping mechanism 7 is misaligned with the limiting recess 72, the opening and closing of the door body 2 is not affected, and when the elastic plunger 71 is opposite to the limiting recess 72, the elastic plunger 71 is clamped into the limiting recess 72 to realize the rotation stopping of the door body 1, thereby avoiding the automatic closing of the door body 1 to affect the user's operation of taking and placing food materials.

[0195] According to this application, the stopping mechanism 7 is provided on the first hinge component (positioning shaft 41 and positioning groove 50) of the hinge assembly. Since the positioning shaft 41 is usually larger in diameter and longer in length, the extension distance of the elastic plunger 71 can be increased, as well as the contact area with the limiting recess 72 can be increased, thereby increasing the stability of the door 2 stopping.

[0196] According to this application, the stopping mechanism 7 is provided on the second hinge member (guide shaft 42 and guide groove 60) of the hinge assembly. Since the guide groove 60 is usually relatively long, the stopping mechanism 7 can be provided at multiple positions in the extension direction of the guide groove 60, thereby meeting the requirement that the door body 2 stops at multiple positions.

[0197] According to this application, setting the stop mechanism 7 in the closed position of the door body 2 can prevent the door body 2 from being opened due to force during transportation and thus causing a collision. By setting the extension range H2 of the limiting protrusion 713 to be less than the distance H1 between the hinge plate 33 and the hinge groove 32, it can prevent the door body 2 from jumping up and impacting the hinge plate 33 during transportation and falling.

[0198] According to this application, the rotating stop mechanism 7 is set at the 90° open position of the door 2 or the maximum open position when embedded in the cabinet, so that the door 2 can be stopped at this position, avoiding the door 2 from closing automatically and the door 2 from colliding with the cabinet.

[0199] According to this application, the rotating stop mechanism 7 is set at the transition point of the hinge assembly 3, which can prevent the door 2 from shaking when passing through the transition point.

[0200] According to this application, the rotation stop mechanism 7 is set at the speed change point of the hinge assembly 3, which can avoid the wear of the hinge shaft 31 and the hinge groove 32 under stress, extend the service life and ensure the stability of the opening and closing of the door 2.

[0201] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
