[0049] With the development of society and the gradual improvement of living quality, people's demand for the aesthetic appearance of household refrigeration equipment installation has become increasingly prominent. Embedding the refrigeration equipment into the cabinet, that is, forming an embedded refrigeration equipment to achieve the unified decoration style of the home improvement method has become increasingly popular. However, in the related art, when the door body of the embedded refrigeration equipment is opened, it is easy to interfere with the surrounding cabinet body, and it is difficult to achieve a large-angle door opening. To solve the above problems to a certain extent, the embodiments of the present application provide a refrigeration equipment that can enable the door body to achieve a large-angle door opening without interfering with the cabinet body.

[0050] The following describes the present application with reference to the accompanying drawings and specific embodiments:

[0051] Please refer to Figure 1 and Figure 2 As shown in, the embodiments of the present application provide a refrigeration equipment 10. The refrigeration equipment 10 provided by the embodiments of the present application is embedded in the cabinet body 20. The refrigeration equipment 10 provided by the embodiments of the present application can enable the door body 200 to achieve a large-angle door opening without interfering with the cabinet body 20.

[0052] Among them, the refrigeration equipment 10 can be a refrigerator-freezer, wine cabinet, cigar cabinet, ice maker or any other refrigeration equipment 10 that can be embedded in the cabinet body 20 and has a door body 200, and there is no limitation thereto.

[0053] The refrigeration equipment 10 is generally rectangular. For the convenience of description, the height direction Z, width direction X, and thickness direction Y are respectively defined. Among them, in the use state of the refrigeration equipment 10, the vertical direction is the height direction Z, the projection of the refrigeration equipment 10 in the vertical direction is a rectangle, where the direction of the long side is the width direction X, and the direction of the short side is the thickness direction Y.

[0054] Similarly, for the convenience of description, six directions of up, down, left, right, front, and back are defined. Among them, in the height direction Z, near the top surface is up, near the bottom surface is down, in the width direction X, the two directions are left and right respectively, and in the thickness direction Y, the connection between the door body 200 and the main body 100 is the back, and the opposite side is the front.

[0055] Please refer to Figures 1 - 6 , in the embodiment of the present application, the refrigeration device 10 includes a main body 100, a door body 200, and a hinge assembly 300. The door body 200 is disposed at the opening 120 of the main body 100. The door body 200 includes a side wall 220 and a front wall 210 disposed at an angle; the hinge assembly 300 includes a first hinge member 310 and a second hinge member 320. The first hinge member 310 is installed on the main body 100, and the second hinge member 320 is installed on the door body 200. A first shaft 311 and a second shaft 312 are fixedly provided on the first hinge member 310. The second hinge member 320 includes a first groove 321 and a second groove 322. The first shaft 311 is slidably engaged with the first groove 321, and the second shaft 312 is slidably engaged with the second groove 322. During the process of the door body 200 being opened from the closed state to the maximum angle, the first shaft 311 slides in the first groove 321, and the second shaft 312 slides in the second groove 322.

[0056] During the process of the door body 200 being opened from the closed state to the maximum angle, the first shaft 311 can slide relative to the first groove 321, so that the first shaft 311 moves away from the front wall 210 and approaches the side wall 220 to form a first trajectory, and moves close to the front wall 210 and approaches the side wall 220 to form a second trajectory; the second shaft 312 can slide relative to the second groove 322, so that the second shaft moves away from the front wall 210 and approaches the side wall 220 to form a third trajectory, and moves close to the front wall 210 and approaches the side wall 220 to form a fourth trajectory.

[0057] Wherein, during the process of the door body 200 being opened from the closed state to the first angle, the first shaft 311 moves along the first trajectory, and the second shaft 312 moves along the third trajectory. During the process of the door body 200 being opened from the first angle to the second angle, the first shaft 311 moves along the second trajectory, and the second shaft 312 continues to move along the third trajectory. During the process of the door body 200 being opened from the second angle to the maximum angle, the first shaft 311 continues to move along the second trajectory, and the second shaft 312 moves along the fourth trajectory, and the distance between the first shaft 311 and the second shaft 312 remains unchanged.

[0058] The main body 100 is a basic component of the refrigeration device 10 and can provide an installation basis for other structures of the refrigeration device 10. The main body 100 has an opening 120 and a receiving cavity 110 for receiving articles. The opening 120 and the receiving cavity 110 are communicated. The door body 200 is installed at the opening 120 of the main body 100 to cooperate with the main body 100 to seal the receiving space and provide a stable receiving space for the articles.

[0059] The refrigeration device 10 is used to freeze or refrigerate items. When it is necessary to place or take out items, the door body 200 needs to be opened. In order to be able to open the door body 200, a hinge assembly 300 with a double-axis and double-slot structure can be used, that is, the door is opened and closed by the shaft sliding in the slot. To ensure the stability of the door body 200 during the opening or closing process, at least two hinge assemblies 300 are provided, and two of the hinge assemblies 300 are respectively arranged on one side of the upper and lower ends of the door body 200. The hinge assembly 300 can be arranged on the left side of the door body 200 or on the right side of the door body 200, and there is no limit to this. For the convenience of description, in the embodiments of the present application, the hinge assembly 300 is arranged on the left side of the upper end of the door body 200 as an example. When the hinge assembly 300 is arranged at the lower end or the right side of the door body 200, the same can be deduced by analogy.

[0060] The first hinge member 310 and the second hinge member 320 rotate relative to each other from the initial state in the forward direction. Corresponding to the refrigeration device 10, this is the state where the door body 200 rotates from the closed state to the open state. The first hinge member 310 and the second hinge member 320 can also rotate relative to each other in the reverse direction and return to the initial state. Corresponding to the refrigeration device 10, this is the state where the door body 200 rotates from the open state to the closed state. For the convenience of understanding and description, in the subsequent description of the process of the shaft moving in the slot, the relative forward rotation of the first hinge member 310 and the second hinge member 320 is taken as the standard, that is, the door body 200 rotates from the closed state to the open state, and no further description will be made hereinafter.

[0061] It should be noted that since the refrigeration device 10 is embedded in the cabinet 20, cabinets 20 are provided on both the left and right sides of the refrigeration device 10. Since the door body 200 may only interfere with the cabinet 20 on one side during the opening process, in this article, the cabinet 20 refers to the cabinet 20 on the side close to the hinge assembly 300, that is, the cabinet 20 on the left side of the refrigeration device 10. The side wall 220 of the door body 200 in this article refers to the side wall 220 on the left side of the door body 200, and the side surface of the main body 100 in this article refers to the side surface on the left side of the main body 100.

[0062] During the opening or closing process of the door body 200, the first shaft 311 slides in the first slot 321, and the second shaft 312 slides in the second slot 322 to restrict the movement trajectory of the door body 200, so that the door body 200 has a tendency to move to the right, thereby improving the situation where the door body 200 collides and interferes with the cabinet 20 during the movement process.

[0063] During the process of the door body 200 being opened from the closed state to the maximum angle, since the first shaft 311 can slide relative to the first groove 321, the first shaft 311 moves away from the front wall 210 to form a first trajectory and moves closer to the front wall 210 to form a second trajectory. That is, the first shaft 311 first moves away from the front wall 210 and then moves closer to the front wall 210. Therefore, the first trajectory and the second trajectory extend in different directions, and the movement trajectory of the first shaft 311 has a turning point. Similarly, since the second shaft 312 can slide relative to the second groove 322 and moves away from the front wall 210 to form a third trajectory, and the second shaft 312 moves closer to the front wall 210 to form a fourth trajectory, the third trajectory and the fourth trajectory extend in different directions, and the movement trajectory of the second shaft 312 also has a turning point.

[0064] By defining the movement trajectories of the first shaft 311 and the second shaft 312, in the initial stage when the door body 200 is opened from the closed state to the first angle, both the first shaft 311 and the second shaft 312 move in the direction away from the front wall 210, so that the door body 200 has a tendency to move in the direction away from the main body 100 to avoid interference between the door body 200 and the main body 100; in the intermediate stage when the door body 200 is opened from the first angle to the second angle, the first shaft 311 first changes the movement direction and moves along the second trajectory in the direction closer to the front wall 210, and the second shaft 312 continues to move along the third trajectory in the direction away from the front wall 210. Through the movement of the first shaft 311 and the second shaft 312 in different directions relative to the front wall 210, the door body 200 can be rotated within a relatively large angle range relative to the main body 100; in the stage when the door body 200 is opened from the second angle to the maximum angle, both the first shaft 311 and the second shaft 312 move in the direction closer to the front wall 210 to facilitate the large-angle opening of the door body 200.

[0065] It can be understood that the longer the movement trajectories of the first shaft 311 and the second shaft 312 are, the larger the opening angle of the door body 200 is. During the process of the door body 200 being opened from the closed state to the maximum angle, since the first shaft 311 and the second shaft 312 first move away from the front wall 210 and then move closer to the front wall 210, that is, the movement trajectories of the first shaft 311 and the second shaft 312 have turning points. When the thickness of the door body 200 is certain, compared with moving in one direction, in the case of having turning points, the first shaft 311 and the second shaft 312 can have longer movement trajectories, so that a large-angle opening of the door can be realized.

[0066] Specifically, the first angle can be 43 - 47°, the second angle can be 88° - 92°, and the maximum angle can be greater than or equal to 120°.

[0067] Next, the overall trajectories of the first shaft 311 and the second shaft 312 will be described in segments:

[0068] Please refer toFigure 7 and Figure 8 In some embodiments, during the process of the door body 200 being opened from the closed state to the third angle, the first shaft 311 moves along a circular arc on the first trajectory, and the second shaft 312 moves along a circular arc on the third trajectory.

[0069] Among them, a part of the first shaft 311 moves along a circular arc on the first trajectory, and a part of the second shaft 312 moves along a circular arc on the third trajectory. That is, during the process of the door body 200 being opened from the closed state to the third angle, the first shaft 311 does not move to the end of the first trajectory, and the second shaft 312 does not move to the end of the second trajectory either.

[0070] The rotation centers of the movement trajectories of the first shaft 311 and the second shaft 312 are not the same, that is, the first shaft 311 and the second shaft 312 rotate non-concentrically. Therefore, the movement trajectories of the first shaft 311 and the second shaft 312 are not parallel and have an intersection point. In this way, the movement trajectories of the first shaft 311 and the second shaft 312 can be made more compact, so that less space can be occupied in the thickness direction of the door body 200, and thus the thickness of the door body 200 can be reduced. The curvature of the movement trajectory of the first shaft 311 and the curvature of the movement trajectory of the second shaft 312 can be the same or different, and there is no limitation on this.

[0071] Specifically, the third angle can be 8° to 12°.

[0072] In some embodiments, the door body 200 is provided with a door seal 240 that cooperates with the opening 120. There is a gap between the door seal 240 and the side wall 220 of the door body 200. During the process of the door body 200 being opened from the closed state to the third angle, the instantaneous center of the first shaft 311 and the second shaft 312 is located in the plane where the side of the door seal 240 is located.

[0073] Among them, perpendicular lines are drawn on the tangents of the movement trajectories of the first shaft 311 and the second shaft 312, and the intersection point of the two perpendicular lines is the instantaneous center. The door seal 240 is a sealing strip, which is used to prevent air, moisture, dust and other impurities from entering the accommodation cavity 110 through the door gap, and improve the sealing performance of the accommodation cavity 110. The side of the door seal 240 refers to the left side of the door seal 240, and the plane where the side of the door seal 240 is located is the YZ plane of the side.

[0074] During the process of the door body 200 opening from the closed state to the third angle, under the action of the rotation of the door body 200, the door body 200 moves away from the cabinet body 20 and also intrudes into the door seal 240. Since the door seal 240 is elastic, the door body 200 will squeeze the door seal 240. If the instantaneous center of the first axis 311 and the second axis 312 is too far from the plane where the side of the door seal 240 is located, the intrusion amount will be too large, and the door seal 240 will twist. Therefore, if the instantaneous center of the first axis 311 and the second axis 312 is located in the plane where the side of the door seal 240 is located, it can be ensured that the intrusion amount of the door body 200 into the door seal 240 is less than 1 mm, reducing the risk of the door seal 240 twisting.

[0075] In some embodiments, the door body 200 is provided with a door seal 240 that cooperates with the opening 120, and there is a gap between the door seal 240 and the side wall 220 of the door body 200. In the process of the door body 200 being opened from a closed state to a third angle, the instantaneous center of the first axis 311 and the second axis 312 is located outside the plane where the side of the door seal 240 is located.

[0076] That is, the instantaneous centers of the first and second axes 311, 312 can also be located outside the plane of the side edges of the door seal 240. As long as the distance between the instantaneous centers of the first and second axes 311, 312 and the plane of the side edges of the door seal 240 is kept small, the risk of the door seal 240 twisting can be reduced. Specifically, the distance between the instantaneous centers of the first and second axes 311, 312 and the plane of the sidewall 220 of the door seal 240 can be less than 10 mm.

[0077] The distance between the instantaneous center of the first axis 311 and the second axis 312 and the plane where the side wall 220 of the door seal 240 is located can be 1 mm, 3 mm, 5 mm, 7 mm, or 9 mm.

[0078] In some embodiments, when the door body 200 opens from the third angle to the fourth angle, the first axis 311 first moves in an arc along the first trajectory and then moves in an arc along the second trajectory, and the second axis 312 moves in an elliptical motion along the third trajectory.

[0079] Here, performing elliptical motion refers to moving along a partial shape of an ellipse, that is, the third trajectory is divided into two segments, one of which is a circular arc and the other is a partial elliptical shape, and the curvatures of the two arcs are different.

[0080] When the door body 200 is opened from the third angle to the fourth angle, the first shaft 311 has moved to the end of the first trajectory and changes its movement direction to enter the second trajectory to perform circular motion, while the second shaft 312 continues to perform elliptical motion along the third trajectory. Therefore, the first shaft 311 passes through the turning point before the second shaft 312. During the turning process of the first shaft 311, the displacement of the first shaft 311 relative to the first groove 321 is extremely small. At this time, if the second shaft 312 is located at the second inflection point 322b simultaneously, it is easy to occur the phenomenon of jamming, resulting in the door body 200 being unable to rotate relative to the main body 100 and causing the failure of opening the door. When the first shaft 311 moves to the turning point, the second shaft 312 moves away from the front wall 210 along the third trajectory, so that when the first shaft 311 changes its movement direction, the door body 200 can still move away from the pivot side, improving the flexibility of the rotation of the door body 200 and avoiding hitting the cabinet body 20 during the process of opening the door.

[0081] Specifically, the fourth angle can be 88° - 92°.

[0082] In some embodiments, when the door body 200 is opened from the fourth angle to the fifth angle, the first shaft 311 performs circular motion along the second trajectory, and the second shaft 312 performs linear motion along the fourth trajectory.

[0083] That is, when the door body 200 is opened from the fourth angle to the fifth angle, the second shaft 312 has passed through the end of the third trajectory and changes its movement direction to enter the fourth trajectory to perform linear motion. During the turning process of the second shaft 312, the displacement of the second shaft 312 relative to the second groove 322 is extremely small. At this time, if the first shaft 311 is located at the turning point simultaneously, it is easy to occur the phenomenon of jamming, resulting in the door body 200 being unable to rotate relative to the main body 100 and causing the failure of opening the door. When the second shaft 312 moves to the turning point, the first shaft 311 moves close to the front wall 210 along the second trajectory, so that when the second shaft 312 changes its movement direction, the door body 200 can still move away from the pivot side, improving the flexibility of the rotation of the door body 200 and avoiding hitting the cabinet body 20 during the process of opening the door.

[0084] Specifically, the fifth angle can be 113° - 117°.

[0085] In some embodiments, when the door body 200 is opened from the fifth angle to the maximum angle, the first shaft 311 rotates about a fixed axis, and the second shaft 31 rotates around the first shaft 311.

[0086] Among them, the first shaft 311 rotates about a fixed axis, that is, the first shaft 311 rotates by itself without sliding relative to the first groove 321. At the same time, the second shaft 312 rotates around the first shaft 311 along the fourth trajectory, that is, the second shaft 312 rotates with the first shaft 311 as the center and will have relative motion with the second groove 322.

[0087] In some embodiments, the shape of the first slot 321 may conform to the movement trajectory of the first shaft 311, and the shape of the second slot 322 may conform to the movement trajectory of the second shaft 312. In this way, the first slot 321 and the second slot 322 can respectively guide the movement of the first shaft 311, so that the first shaft 311 and the second shaft 312 can accurately move along the set trajectory, thereby improving the accuracy of the rotation of the door body 200.

[0088] Please refer to Figure 6 , in some embodiments, the first slot 321 includes a first inflection point 321b, a first end point 321a, and a second end point 321c; the first inflection point 321b is located between the first end point 321a and the second end point 321c and on the side of the first slot 321 away from the front wall 210; the second slot 322 includes a second inflection point 322b, a third end point 322a, and a fourth end point 322c, and the second inflection point 322b is located between the third end point 322a and the fourth end point 322c and on the side of the second slot 322 away from the front wall 210;

[0089] Wherein, during the process of the door body 200 opening from the closed state to the maximum angle, when the first shaft 311 moves from the first end point 321a towards the first inflection point 321b, the second shaft 312 moves from the third end point 322a towards the second inflection point 322b; when the first shaft 311 moves from the first inflection point 321b towards the second end point 321c, the second shaft 312 slides towards the second inflection point 322b and passes through the second inflection point 322b towards the fourth end point 322c.

[0090] It can be understood that the first inflection point 321b corresponds to the turning point of the movement trajectory of the first shaft 311, and the second inflection point 322b corresponds to the turning point of the movement trajectory of the second shaft 312. Since the first shaft 311 slides in the first slot 321 and the second shaft 312 slides in the second slot 322, the stroke of the first shaft 311 is approximately equal to the length of the first slot 321, and the stroke of the second shaft 312 is approximately equal to the length of the second slot 322. That is, the longer the length of at least one of the first slot 321 and the second slot 322, the larger the opening angle of the door body 200.

[0091] Specifically, in the first slot 321, the slot section between the first end point 321a and the first inflection point 321b conforms to the first trajectory, and the slot section between the first inflection point 321b and the first end point 321a conforms to the second trajectory; in the second slot 322, the slot section between the third end point 322a and the second inflection point 322b conforms to the third trajectory, and the slot section between the second inflection point 322b and the fourth end point 322c conforms to the fourth trajectory.

[0092] During the process of the door body 200 being opened from the closed state to the maximum angle, the first shaft 311 moves from the first end point 321a through the first inflection point 321b to the second end point 321c, such that the first shaft 311 first moves away from the front wall 210 and then moves closer to the front wall 210. The second shaft 312 moves from the third end point 322a through the second inflection point 322b to the fourth end point 322c, such that the second shaft 312 first moves away from the front wall 210 and then moves closer to the front wall 210. That is, during the door opening process, the trajectory of the first shaft 311 at least partially overlaps in the thickness direction of the door body 200 (the first groove 321 at least partially overlaps in the thickness direction of the door body 200), and the trajectory of the second shaft 312 also at least partially overlaps in the thickness direction of the door body 200 (the second groove 322 at least partially overlaps in the thickness of the door body 200). That is, in the case of the same trajectory length, the first groove 321 has the first inflection point 321b and the second groove 322 has the second inflection point 322b, so that in the case of the same trajectory length, a smaller space can be occupied in the thickness direction of the door body 200, the thickness of the door body 200 can be reduced, and large-angle door opening can be realized in the case of an ultra-thin door.

[0093] Specifically, when the door body 200 is in the closed state, the first shaft 311 is located at the first end point 321a, and the second shaft 312 is located at the third end point 322a; when the door body 200 is opened to 45°, the first shaft 311 is located at the first inflection point 321b, and the second shaft 312 is located between the third end point 322a and the second inflection point 322b; when the door body 200 is opened to 90°, the first shaft 311 is located between the first inflection point 321b and the second end point 321c, and the second shaft 312 is located at the second inflection point 322b; when the door body 200 is opened to the maximum angle, the first shaft 311 is located at the second end point 321c, and the second shaft 312 is located at the fourth end point 322c.

[0094] In some embodiments, when the first shaft 311 is located at the first inflection point 321b, the second shaft 312 is offset from the second inflection point 322b; when the second shaft 312 is located at the second inflection point 322b, the first shaft 311 is offset from the first inflection point 321b.

[0095] It can be understood that the first shaft 311 needs to change the movement direction at the first inflection point 321b and the second shaft 312 needs to change the movement direction at the second inflection point 322b, and the displacements of the first shaft 311 at the first inflection point 321b and the second shaft 312 at the second inflection point 322b are small; if the second shaft 312 is simultaneously located at the second inflection point 322b when the first shaft 311 is at the first inflection point 321b, then the first shaft 311 and the second shaft 312 change the movement direction simultaneously. At this time, the relative displacements of the first shaft 311 with respect to the first groove 321 and the second shaft 312 with respect to the second groove 322 are small, resulting in a small amplitude of rotation of the door body 200 relative to the main body 100, and it is easy to cause a jamming phenomenon.

[0096] When the first shaft 311 is located at the first inflection point 321b, the second shaft 312 is offset from the second inflection point 322b. The first shaft 311 changes its moving direction in the first groove 321 and the displacement of the first shaft 311 relative to the first groove 321 is very small. The second shaft 312 is offset from the second inflection point 322b. The second shaft 312 can move between the third end point 322a and the second inflection point 322b, or the second shaft 312 can move between the fourth end point 322c and the second inflection point 322b. When the second shaft 312 is located at the second inflection point 322b, the first shaft 311 is offset from the first inflection point 321b. The second shaft 312 changes its moving direction in the second groove 322 and the displacement of the second shaft 312 relative to the second groove 322 is very small. The first shaft 311 is offset from the first inflection point 321b. The first shaft 311 can move between the first end point 321a and the first inflection point 321b, or the first shaft 311 can move between the second end point 321c and the first inflection point 321b. When one of the first shaft 311 and the second shaft 312 is located at the corresponding inflection point, the other is offset from the corresponding inflection point and makes a large-range displacement relative to the corresponding groove, making the rotation between the first hinge member 310 and the second hinge member 320 more flexible and ensuring that the door body 200 can be smoothly opened without exceeding the side of the main body 100.

[0097] In some embodiments, when the first shaft 311 is located at the first inflection point 321b, the first shaft 311 changes its moving direction at the first inflection point 321b, changing from moving from the first end point 321a towards the first inflection point 321b to moving from the first inflection point 321b towards the second end point 321c. During this turning process, the displacement of the first shaft 311 relative to the first groove 321 is extremely small. At this time, if the second shaft 312 is also located at the second inflection point 322b, it is easy to occur the phenomenon of jamming, resulting in the door body 200 being unable to rotate relative to the main body 100 and causing the failure of opening the door. When the first shaft 311 is located at the first inflection point 321b, the second shaft 312 moves from the third end point 322a towards the second inflection point 322b, and the second shaft 312 is away from the front wall 210, so that when the first shaft 311 changes its moving direction in the first groove 321, the door body 200 can still move away from the pivot side, improving the flexibility of the rotation of the door body 200 and avoiding hitting the cabinet body 20 during the process of opening the door.

[0098] In some embodiments, when the second shaft 312 is located at the second inflection point 322b, the second shaft 312 changes its movement direction at the second inflection point 322b, changing from moving from the third end point 322a towards the second inflection point 322b to moving from the second inflection point 322b towards the fourth end point 322c. During this turning process, the displacement of the second shaft 312 relative to the second groove 322 is extremely small. At this time, if the first shaft 311 is simultaneously located at the first inflection point 321b, a jamming phenomenon is likely to occur, resulting in the door body 200 being unable to rotate relative to the main body 100 and causing the door opening to fail. When the second shaft 312 is located at the second inflection point 322b, the first shaft 311 moves towards the second end point 321c, and the first shaft 311 approaches the front wall 210, so that when the second shaft 312 changes its movement direction within the second groove 322, the door body 200 can still move away from the pivot side, improving the flexibility of the rotation of the door body 200 and avoiding hitting the cabinet body 20 during the door opening process.

[0099] In some embodiments, during the process of the door body 200 rotating relative to the main body 100 to the maximum angle, after the first shaft 311 passes through the first inflection point 321b, the second shaft 312 passes through the second inflection point 322b, avoiding the phenomenon that the first shaft 311 and the second shaft 312 are simultaneously located at the inflection points, resulting in the door body 200 jamming or pausing during the door opening process, making the door opening process of the door body 200 smoother and improving the user experience. The first shaft 311 is closer to the pivot side than the second shaft 312. The first shaft 311 passes through the first inflection point 321b first, so that the first shaft 311 no longer moves away from the front wall 210, while the second shaft 312 has not reached the second inflection point 322b, and the second shaft 312 continues to move away from the front wall 210, enabling the door body 200 to rotate a larger angle relative to the main body 100 during this process.

[0100] Please refer to Figures 7 - 9 , in some embodiments, when the door body 200 is in the closed state, the distance A0 between the first shaft 311 and the front wall 210 is 10 mm to 20 mm, the distance B0 between the first shaft 311 and the side wall 220 is 17 mm to 27 mm, the distance C0 between the second shaft 312 and the front wall 210 is 6 mm to 16 mm, and the distance D0 between the second shaft 312 and the side wall 220 is 30 mm to 40 mm.

[0101] Since, in the closed state of the door body 200, the distances between the first shaft 311 and the front wall 210, between the first shaft 311 and the side wall 220, between the second shaft 312 and the front wall 210, and between the second shaft 312 and the side wall 220 are defined as relatively small values, that is, the first shaft 311 and the second shaft 312 are arranged compactly. Since the first shaft 311 is in sliding fit with the first groove 321 and the second shaft 312 is in sliding fit with the second groove 322, therefore, the first groove 321 and the second groove 322 are also arranged compactly accordingly, thereby reducing the occupied space of the hinge assembly 300, enabling the thickness of the door body 200 to be thinner and meeting the ultra-thin door requirement of the refrigeration device 10.

[0102] Specifically, the distance A0 between the first shaft 311 and the front wall 210 can be 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, the distance B0 between the first shaft 311 and the side wall 220 can be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, the distance C0 between the second shaft 312 and the front wall 210 can be 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, and the distance D0 between the second shaft 312 and the side wall 220 can be 23 mm, 25 mm, 27 mm, 29 mm, 31 mm.

[0103] Among them, the distance between the first shaft 311 and the front wall 210 represents the vertical distance between the axis center of the first shaft 311 and the front wall 210, and the distance between the first shaft 311 and the side wall 220 represents the vertical distance between the axis center of the first shaft 311 and the side wall 220. Similarly, the distance between the second shaft 312 and the front wall 210 represents the vertical distance between the axis center of the second shaft 312 and the front wall 210, and the distance between the second shaft 312 and the side wall 220 represents the vertical distance between the axis center of the first shaft 311 and the front wall 210.

[0104] It should be noted that the door body 200 may include a rear wall 230 opposite to the front wall 210, and a door seal 240 is provided on the rear wall 230. In the case where the door body 200 is in the closed state, the door seal 240 is clamped between the rear wall 230 and the main body 100, playing a role in sealing and heat insulation. When the door body 200 is closed from the open state, due to the elasticity of the door seal 240, the door body 200 may slightly squeeze the door seal 240, forming a negative closing angle of -1° to -5°. In the state of the negative closing angle, the sealing performance between the door body 200 and the opening 120 is better. Therefore, in this article, the case where the door body 200 is in the closed state may refer to both the state where the relative angle between the door body 200 and the main body 100 is 0°, and the state of the negative closing angle of the door body 200.

[0105] In some embodiments, when the door body 200 is in the closed state, the distance W0 between the axis of the first shaft 311 and the axis of the second shaft 312 in the thickness direction of the door body 200 is less than 10 mm.

[0106] By defining the interval between the axis of the first shaft 311 and the axis of the second shaft 312 in the thickness direction of the door body 200, the distance between the first shaft 311 and the second shaft 312 is constrained, so that the layout of the first shaft 311 and the second shaft 312 is further compact, and the occupied space of the hinge assembly 300 is reduced.

[0107] Specifically, the distance W0 between the axis of the first shaft 311 and the axis of the second shaft 312 in the thickness direction of the door body 200 can be 1 mm, 3 mm, 5 mm, 7 mm, 9 mm.

[0108] In some embodiments, when the door body 200 is in the closed state, the angle α0 between the connection line of the axis of the first shaft 311 and the axis of the second shaft 312 and the front wall 210 is less than 35°.

[0109] The angle α0 between the connection line of the axes of the first shaft 311 and the second shaft 312 and the front wall 210 represents the distance W0 between the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200. The smaller the angle α0 between the connection line of the axes of the first shaft 311 and the second shaft 312 and the front wall 210, the closer the distance W0 between the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200 when the first shaft 311 is located at the first end point 321a. Compared with the first shaft 311 and the second shaft 312 located at the middle position in the thickness direction of the door body 200, the distance W0 between the first shaft 311 and the second shaft 312 and the front wall 210 is closer, so that the first shaft 311 and the second shaft 312 can have more movement space during the door opening process, and the thickness of the door body 200 can be reduced when the hinge assembly 300 with the same opening angle is arranged.

[0110] Specifically, when the door body 200 is in the closed state, the angle α0 between the connection line of the axis of the first shaft 311 and the axis of the second shaft 312 and the front wall 210 can be 25°, 30°, 34°.

[0111] In some embodiments, when the door body 200 is in the closed state, there is a first distance B0 between the first shaft 311 and the side wall 220. When the relative angle between the door body 200 and the main body 100 is 90°, there is a second distance A2 between the first shaft 311 and the front wall 210. The difference between the first distance B0 and the second distance A2 is less than or equal to 2 mm.

[0112] The intrusion amount is the distance between the second edge 222 at the junction of the rear wall 230 and the side wall 220 and the side surface of the box body 100; it should be noted that the door body 200 may be provided with an arc chamfer, so that the rear wall 230 and the side wall 220 are connected through an arc surface. At this time, the intrusion amount can be the distance between the connecting edge of the arc surface and the rear wall 230 or the side wall 220 and the side surface of the box body 100, or the intrusion amount can also be the distance between the midpoint of the arc of the arc surface and the side surface of the box body 100. The door body 200 may be provided with an inclined chamfer, so that the rear wall 230 and the side wall 220 are connected through an inclined surface. At this time, the intrusion amount can be the distance between the connecting edge of the inclined surface and the rear wall 230 and the side surface of the box body 100, or the intrusion amount can also be the distance between the connecting edge of the inclined surface and the side wall 220 and the side surface of the box body 100.

[0113] A drawer will be arranged in the accommodation cavity 110 of the main body 100 to store items. When the user takes items, the drawer needs to be pulled out. Therefore, in order to avoid interference between the drawer and the door body 200, the drawer can only be arranged in the space of the main body 100 that is not invaded by the door body 200. Since the width of the main body 100 is a fixed value, the larger the intrusion amount, the smaller the width of the drawer, and thus the smaller the space for accommodating items.

[0114] It can be understood that when the door body 200 is in the closed state, the side wall 220 of the door body 200 is aligned with the side surface of the main body 100. Therefore, the distance between the axis of the first shaft 311 and the side wall 220 at this time is the distance between the axis of the first shaft 311 and the side surface of the main body 100, that is, the first distance B0; when the relative angle between the door body 200 and the main body 100 is 90°, at this time the side wall 220 rotates to be perpendicular to the side surface of the main body 100, and the front wall 210 is parallel to the main body 100. Because the first shaft 311 is relatively fixed to the main body 100, by calculating the difference between the second distance A2 between the axis of the first shaft 311 and the front wall 210 and the first distance B0, the vertical distance between the front wall 210 and the side surface of the main body 100 in the state where the door body 200 is opened to 90° can be deduced. Since the thickness of the door body 200 is fixed, the intrusion amount of the door body 200 in the 90° state can be calculated. By limiting the difference between the first distance B0 and the second distance A2 to be less than or equal to 2 mm, the intrusion amount of the door body 200 can be controlled within a very small range, thereby improving the use experience of the refrigeration device 10.

[0115] Specifically, the difference between the first distance and the second distance can be 0.5 mm, 1 mm, 1.5 mm.

[0116] In some embodiments, when the door body 200 is opened from the closed state, the angle β0 between the tangent of the moving direction of the first shaft 311 relative to the first groove 321 and the front wall 210 is less than 50°, and the angle γ0 between the tangent of the moving direction of the second shaft 312 relative to the second groove 322 and the front wall 210 is less than 75°.

[0117] By setting the angle formed by the tangent of the moving direction and the front wall 210 to be relatively small, the first shaft 311 and the second shaft 312 can slide as much as possible in the width direction of the door body 200, reducing the moving stroke of the first shaft 311 and the second shaft 312 in the thickness direction, reducing the occupied space in the thickness direction of the door body 200, so that a hinge assembly 300 capable of realizing large-angle door opening can be arranged on the ultra-thin door body 200, reducing the thickness of the door body 200.

[0118] Specifically, when the door body 200 is opened from the closed state, the angle β0 formed by the tangent of the moving direction of the first shaft 311 relative to the first groove 321 and the front wall 210 can be 25°, 35°, 45°, and the angle γ0 formed by the tangent of the moving direction of the second shaft 312 relative to the second groove 322 and the front wall 210 can be 50°, 60°, 70°.

[0119] In some embodiments, when the door body 200 is opened from the closed state, the angle θ0 between the tangent of the moving direction of the first shaft 311 relative to the first groove 321 and the tangent of the moving direction of the second shaft 312 relative to the second groove 322 is 15° to 50°.

[0120] By setting the angle θ0 between the moving tangent of the first shaft 311 and the moving tangent of the second shaft 312 to be relatively small, the movement trajectories of the first shaft 311 and the second shaft 312 can be made more compact, reducing the occupied space in the thickness direction of the door body 200, so that a hinge assembly 300 capable of realizing large-angle door opening can be arranged on the ultra-thin door body 200, reducing the thickness of the door body 200.

[0121] Specifically, when the body is opened from the closed state, the angle θ0 between the tangent of the moving direction of the first shaft 311 relative to the first groove 321 and the tangent of the moving direction of the second shaft 312 relative to the second groove 322 can be 20°, 25°, 30°, 35°, 45°.

[0122] In some embodiments, when the door body 200 is in the closed state, there is a gap between the first shaft 311 and the end of the first groove 321, and there is a gap between the second shaft 312 and the end of the second groove 322.

[0123] In order to enable the door body 200 to form a negative closing angle of -1° to -5°, so as to prevent the end parts of the first groove 321 and the second groove 322 from restricting the movement of the first shaft 311 and the second shaft 312 respectively, there is a gap between the first shaft 311 and the end part of the first groove 321, and there is a gap between the second shaft 312 and the end part of the second groove 322. Thus, when the door body 200 is in the closed state, the first shaft 311 and the second shaft 312 can move in the corresponding gaps, so as to ensure that the door body 200 has a certain negative closing angle and ensure the sealing performance when the door body 200 is closed.

[0124] In some embodiments, the distance between the main body 100 and the cabinet body 20 is 0 mm to 6 mm.

[0125] Since the maximum over-box amount of the door body 200 during rotation in the embodiments of the present application is only less than or equal to 1 mm, that is, the over-box amount of the door body 200 during rotation is small, so the door body 200 is not likely to interfere with the cabinet body 20. Therefore, the distance between the main body 100 and the cabinet body 20 can be set relatively close to improve the space utilization rate and enhance the aesthetic appearance of the installation of the refrigeration device 10.

[0126] Specifically, the distance between the main body 100 and the cabinet body 20 can be 1 mm, 2 mm, 3 mm, 4 mm, 5 mm.

[0127] In some embodiments, the thickness of the door body 200 is 30 mm to 50 mm.

[0128] Since the movement trajectories of the first shaft 311 and the second shaft 312 in the embodiments of the present application are relatively compact, and the first shaft 311 slides in the first groove 321 and the second shaft 312 slides in the second groove 322, the arrangements of the first groove 321 and the second groove 322 are also relatively compact accordingly. That is, the movement space of the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200 and the arrangement space of the first groove 321 and the second groove 322 in the thickness direction of the door body 200 are both small, so that the thickness of the door body 200 in the Y direction can be set thinner to improve the aesthetic appearance and save space.

[0129] Specifically, the thickness of the door body 200 can be 32 mm, 34 mm, 38 mm, 42 mm, 46 mm.

[0130] In some embodiments, the first hinge member 310 further includes a first mounting member 313. The first mounting member 313 includes a connecting portion 313a and a mounting portion 313b. The connecting portion 313a is fixedly connected to the main body 100, the mounting portion 313b is located outside the main body 100, and the first shaft 311 and the second shaft 312 are fixedly arranged on the mounting portion 313b.

[0131] To facilitate the connection between the first mounting member 313 and the main body 100, the first mounting member 313 can be a plate-like structure. Among them, a part of the first mounting member 313 overlaps and is connected to the main body 100, and the remaining part of the first mounting member 313 extends out of the main body 100. The part where the first mounting member 313 overlaps and is connected to the main body 100 is the connecting portion 313a, and the part where the first mounting member 313 extends out of the main body 100 is the mounting portion 313b. Since the door body 200 moves relative to the main body 100, the sliding fits between the first shaft 311 and the first slot 321, and between the second shaft 312 and the second slot 322 are both located on the door body 200. Since the first shaft 311 and the second shaft 312 are fixedly arranged on the mounting portion 313b and the mounting portion 313b is located outside the main body 100, the first shaft 311 and the second shaft 312 can correspond to the first slot 321 and the second slot 322 on the door body 200 respectively.

[0132] Specifically, the first mounting member 313 is arranged on the top surface of the main body 100, and the first shaft 311 and the second shaft 312 are arranged below the mounting portion 313b, so that the first shaft 311 and the second shaft 312 can be respectively located in the first slot 321 and the second slot 322. The connecting portion 313a can be connected to the top surface of the main body 100 by any detachable means such as screwing or clamping, and no limitation is imposed on this.

[0133] In some embodiments, the second hinge member 320 further includes a second mounting member 323. The first slot 321 and the second slot 322 are provided on the second mounting member 323, and the door body 200 is provided with a mounting slot 250, and the second mounting member 323 is mounted in the mounting slot 250.

[0134] Since the first slot 321 and the second slot 322 need to be opened on the second mounting member 323, the second mounting member 323 can be a block-like structure with a certain thickness to facilitate slotting. And since the second mounting member 323 is a block-like structure, in order to reduce the occupied space of the second mounting member 323 and make the overall appearance of the door body 200 more concise, the door body 200 is provided with a mounting slot 250, and the second mounting member 323 is mounted in the mounting slot 250. The second mounting member 323 can be flush with the opening 120 of the mounting slot 250. In this way, the second mounting member 323 does not additionally occupy the space of the door body 200. Specifically, the mounting slot 250 is opened on the top wall of the door body 200, so that the second mounting member 323 is arranged at the upper end of the door body 200 to cooperate with the first hinge member 310.

[0135] Please refer to Figures 10 - 14, in some embodiments, the side wall 220 intersects the front wall 210 at a first edge 221. When the first edge 221 is at a first position, the distance A1 between the first axis 311 and the front wall 210 is 13 mm to 23 mm, the distance B1 between the first axis 311 and the side wall 220 is 9 mm to 19 mm, the distance C1 between the second axis 312 and the front wall 210 is 19 mm to 29 mm, and the distance D1 between the second axis 312 and the side wall 220 is 22 mm to 32 mm. Herein, the first position represents the position where the distance between the first edge 221 and the cabinet 20 is the smallest.

[0136] The door body 200 further includes a rear wall 230 disposed opposite to the front wall 210. The rear wall 230 faces the opening 120 of the main body 100, and the rear wall 230 intersects the side wall 220 at a second edge 222. During the rotation of the door body 200 relative to the main body 100, the second edge 222 can move away from the cabinet 20, while the first edge 221 moves closer to the cabinet 20. When the door body 200 rotates to a certain angle, the distance between the first edge 221 and the cabinet 20 is the smallest. At this time, the first edge 221 is at the first position. After the door body 200 rotates through this angle and continues to rotate, the first edge 221 moves away from the cabinet 20, and the second edge 222 moves closer to the cabinet 20.

[0137] That is, the situation where the first edge 221 is at the first position occurs during the rotation of the door body 200. Specifically, when the rotation angle of the door body 200 relative to the main body 100 is 40° to 50°, the first edge 221 is at the first position.

[0138] In the embodiments of the present application, since when the first edge 221 is at the first position, the distances between the first axis 311 and the front wall 210, the first axis 311 and the side wall 220, the second axis 312 and the front wall 210, and the second axis 312 and the side wall 220 are limited to relatively small values, that is, the movement trajectories of the first axis 311 and the second axis 312 are relatively compact. Since the first axis 311 is slidably engaged with the first groove 321 and the second axis 312 is slidably engaged with the second groove 322, therefore, the first groove 321 and the second groove 322 are also compactly arranged, thereby reducing the occupied space of the hinge assembly 300, enabling the thickness of the door body 200 to be thinner, and meeting the ultra-thin door requirements of the refrigeration device 10.

[0139] Specifically, the distance A1 between the first axis 311 and the front wall 210 can be 14 mm, 16 mm, 18 mm, 20 mm, 22 mm, and the distance BA between the first axis 311 and the side wall 220 can be 10 mm, 12 mm, 14 mm, 16 mm, 18 mm. The distance C1 between the second axis 312 and the front wall 210 can be 20 mm, 22 mm, 24 mm, 26 mm, 28 mm, and the distance D1 between the second axis 312 and the front wall 210 can be 23 mm, 25 mm, 27 mm, 29 mm, 31 mm.

[0140] In some embodiments, when the first edge 221 is in the first position, the distance L1 by which the first edge 221 extends beyond the side surface of the main body 100 is less than or equal to 1 mm.

[0141] It can be understood that the side surface of the main body 100 is the surface of the main body 100 close to the cabinet 20. When the door body 200 is in the closed state, the side wall 220 can be flush with the side surface of the main body 100, that is, the first edge 221 is aligned with the side surface of the main body 100. When the door body 200 is opened from the closed state, the first edge 221 will move relatively to the left of the main body 100, and when the door body 200 is opened to a certain angle, it will extend out beyond the side surface of the main body 100, thus there is a risk of interference with the cabinet 20.

[0142] When the first edge 221 is in the first position, the distance between the first edge 221 and the cabinet 20 is the smallest, that is, when the first edge 221 is at the position where it extends the farthest beyond the side surface of the main body 100. To avoid contact between the first edge 221 and the cabinet 20, it is defined that when the first edge 221 is in the first position, the distance between the first edge 221 and the side surface of the main body 100 is less than or equal to 1 mm, that is, the maximum amount by which the first edge 221 extends beyond the box is less than or equal to 1 mm. Thus, as long as the distance between the refrigeration device 10 and the cabinet 20 is greater than 1 mm, the door body 200 can be smoothly opened, meeting the requirements of embedded installation.

[0143] Specifically, when the first edge 221 is in the first position, the distance L1 between the first edge 221 and the side surface of the main body 100 can be 0.1 mm, 0.3 mm, 0.5 mm, 0.7 mm, 0.9 mm or other values less than 1 mm, which are not specifically limited herein.

[0144] In some embodiments, when the first edge 221 is in the first position, the distance L2 between the first edge 221 and the cabinet 20 is greater than or equal to 1 mm.

[0145] When the first edge 221 is in the first position, the distance between the first edge 221 and the cabinet body 20 is the smallest. By defining the distance between the first edge 221 and the cabinet body 20, even when the first edge 221 extends the farthest from the side of the main body 100, it is not easy to interfere with the cabinet body 20.

[0146] Specifically, when the first edge 221 is in the first position, the distance L2 between the first edge 221 and the cabinet body 20 can be 1mm, 1.5mm, or 2mm.

[0147] In some embodiments, when the first edge 221 is in the first position, the distance W1 in the thickness direction of the door body 200 between the axis of the first shaft 311 and the axis of the second shaft 312 is less than 12mm.

[0148] When the door body 200 rotates to the position where the first edge 221 is in the first position, the distance in the Y direction between the axis of the first shaft 311 and the axis of the second shaft 312 is short, that is, the movement trajectories of the first shaft 311 and the second shaft 312 are relatively compact, and the distance between the first shaft 311 and the second shaft 312 always remains short. Since the first shaft 311 slides in the first groove 321 and the second shaft 312 slides in the second groove 322, the arrangements of the first groove 321 and the second groove 322 are also correspondingly relatively compact. Thus, on the premise of ensuring the rotation angle of the door body 200, the thickness of the door body 200 in the Y direction can be made thinner to meet the ultra-thin door requirement of the refrigeration device 10.

[0149] Specifically, the distance W1 in the thickness direction of the door body 200 between the axis of the first shaft 311 and the axis of the second shaft 312 can be 4mm, 5mm, 7mm, 9mm, or 11mm.

[0150] In some embodiments, when the first edge 221 is in the first position, the included angle α1 between the connection line of the axis of the first shaft 311 and the axis of the second shaft 312 and the front wall 210 is less than 35°.

[0151] The included angle between the axis connection line of the first shaft 311 and the second shaft 312 and the front wall 210 represents the distance between the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200. The smaller the included angle between the axis connection line of the first shaft 311 and the second shaft 312 and the front wall 210, the closer the distance between the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200 when the first shaft 311 is located at the first end point 321a. Compared with the middle position of the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200, the closer the first shaft 311 and the second shaft 312 are to the front wall 210, so that the first shaft 311 and the second shaft 312 can have more movement space during the door opening process, and the thickness of the door body 200 can be reduced when arranging the hinge assembly 300 with the same opening angle.

[0152] Specifically, when the first edge 221 is located at the first position, the included angle α1 between the axis connection line of the first shaft 311 and the second shaft 312 and the front wall 210 can be 30°, 32°, 34°.

[0153] In some embodiments, the rear wall 230 intersects the side wall 220 at a second edge 222. When the first edge 221 is located at the first position, the distance L3 between the second edge 222 and the main body 100 is greater than 10 mm.

[0154] It can be understood that during the process of the door body 200 rotating to the position where the first edge 221 is located at the first position, while the second edge 222 moves away from the cabinet body 20, it also moves closer to the main body 100. By restricting the distance between the second edge 222 and the main body 100 when the first edge 221 is located at the first position, interference between the second edge 222 and the main body 100 can be avoided to a certain extent.

[0155] Specifically, when the first edge 221 is located at the first position, the distance L3 between the second edge 222 and the main body 100 can be 11 mm, 12 mm, 13 mm, 14 mm, 15 mm.

[0156] Please refer to Figures 15 - 18 , in some embodiments, when the relative angle between the door body 200 and the main body 100 is 90°, the distance A2 between the first shaft 311 and the front wall 210 is 12 mm to 22 mm, the distance B2 between the first shaft 311 and the side wall 220 is 7 mm to 17 mm, the distance C2 between the second shaft 312 and the front wall 210 is 25 mm to 35 mm, and the distance D2 between the second shaft 312 and the side wall 220 is 13 mm to 23 mm.

[0157] When the relative angle between the door body 200 and the main body 100 is 90°, limiting the distances between the first shaft 311 and the front wall 210, and between the second shaft 312 and the front wall 210 to relatively small values is beneficial to reducing the moving distances of the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200 during the process of the door body 200 rotating from the closed state to a relative angle of 90° with the main body 100, which is conducive to meeting the design requirements of an ultra-thin door; limiting the distances between the first shaft 311 and the side wall 220, and between the second shaft 312 and the side wall 220 to relatively small values facilitates the door body 200 to continue opening to the maximum angle without interfering with the extraction of the drawer; in addition, restricting the distance between the axis of the first shaft 311 and the front wall 210 is beneficial to reducing the moving distance of the door body 200 towards the main body 100 during the process of the door body 200 rotating from the closed state to a relative angle of 90° with the main body 100, reducing the probability of the door body 200 squeezing the main body 100, and facilitating the extraction of the drawer inside the main body 100.

[0158] Specifically, when the relative angle between the door body 200 and the main body 100 is 90°, the distance A2 between the first shaft 311 and the front wall 210 can be 13mm, 15mm, 17mm, 19mm, 21mm, and the distance B2 between it and the side wall 220 can be 8mm, 10mm, 12mm, 14mm, 16mm; the distance C2 between the second shaft 312 and the front wall 210 can be 26mm, 28mm, 30mm, 32mm, 34mm, and the distance D2 between it and the side wall 220 can be 14mm, 16mm, 18mm, 20mm, 22mm.

[0159] In some embodiments, when the relative angle between the door body 200 and the main body 100 is 90°, the inward displacement L4 of the door body 200 is less than or equal to 2mm.

[0160] The inward displacement is the difference between the intrusion amount and the thickness of the door body 200. When the relative angle between the door body 200 and the box body 100 is 90°, the inward displacement is the distance between the front wall 210 and the side surface of the box body 100, and the intrusion amount is the sum of the inward displacement of the door body 200 and the thickness of the door body 200. Since the thickness of the door body 200 is a fixed value, in the embodiments of the present application, by limiting the inward displacement L4 of the door body 200 to be less than or equal to 2mm, the intrusion amount of the door body 200 can be controlled within a relatively small range, improving the user experience.

[0161] Specifically, when the relative angle between the door body 200 and the box body 100 is 90°, the inward displacement L4 of the door body 200 can be 0.5mm, 1mm, 1.5mm.

[0162] In some embodiments, when the relative angle between the door body 200 and the main body 100 is 90°, the included angle α2 between the connecting line of the axis of the first shaft 311 and the axis of the second shaft 312 and the front wall 210 is less than 70°.

[0163] The included angle between the connecting line of the axes of the first shaft 311 and the second shaft 312 and the front wall 210 represents the distance between the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200. The smaller the included angle between the connecting line of the axes of the first shaft 311 and the second shaft 312 and the front wall 210, the closer the distance between the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200 when the first shaft 311 is located at the first end point 321a. Compared with the first shaft 311 and the second shaft 312 being located at the middle position in the thickness direction of the door body 200, the closer the first shaft 311 and the second shaft 312 are to the front wall 210, so that the first shaft 311 and the second shaft 312 can have more movement space during the door opening process, and the thickness of the door body 200 can be reduced when arranging the hinge assembly 300 with the same opening angle.

[0164] Specifically, when the relative angle between the door body 200 and the main body 100 is 90°, the included angle α2 between the connecting line of the axis of the first shaft 311 and the axis of the second shaft 312 and the front wall 210 can be 50°, 55°, 60°, 65°, 68°.

[0165] In some embodiments, when the relative angle between the door body 200 and the main body 100 is 90°, the distance W2 between the axis of the first shaft 311 and the axis of the second shaft 312 in the thickness direction of the door body 200 is 7 mm to 19 mm.

[0166] By limiting the interval between the axis of the first shaft 311 and the axis of the second shaft 312 in the thickness direction of the door body 200 when the relative angle between the door body 200 and the main body 100 is 90°, the distance between the first shaft 311 and the second shaft 312 is constrained, making the layout of the first shaft 311 and the second shaft 312 compact and reducing the occupied space, thereby reducing the thickness of the door body 200.

[0167] Specifically, when the relative angle between the door body 200 and the main body 100 is 90°, the distance W2 between the axis of the first shaft 311 and the axis of the second shaft 312 in the thickness direction of the door body 200 can be 8 mm, 10 mm, 12 mm, 14 mm, 16 mm.

[0168] In some embodiments, when the relative angle between the door body 200 and the main body 100 is 90°, the distance L5 between the door body 200 and the main body 100 is 20 mm to 30 mm

[0169] When the relative angle between the door body 200 and the main body 100 is 90°, the side wall 220 is arranged parallel to the opening 120 of the main body 100. Therefore, the distance between the door body 200 and the main body 100 is the vertical distance between the side wall 220 and the plane where the opening 120 of the main body 100 is located. Since the door body 200 and the main body 100 are connected by the sliding fit between the first shaft 311 and the first groove 321, and the second shaft 312 and the second groove 322, that is, dynamically connected. If the distance between the door body 200 and the main body 100 is too far, it will cause the connection between the door body 200 and the main body 100 to be unstable. Therefore, the distance between the door body 200 and the main body 100 is limited to make the connection more stable.

[0170] Specifically, when the relative angle between the door body 200 and the main body 100 is 90°, the distance L5 between the door body 200 and the main body 100 can be 21mm, 23mm, 25mm, 27mm, 29mm.

[0171] In some embodiments, the intrusion amount H1 when the relative angle between the door body 200 and the main body 100 is 90° is greater than the intrusion amount H2 when the relative angle between the door body 200 and the main body 100 is the largest.

[0172] A drawer will be arranged in the accommodation cavity 110 of the main body 100 to store items. When the user takes the items, the drawer needs to be pulled out. Therefore, in order to avoid interference between the drawer and the door body 200, the drawer can only be arranged in the space on the main body 100 that is not invaded by the door body 200. Since the width of the main body 100 is a fixed value, the larger the intrusion amount, the smaller the width of the drawer, and thus the smaller the space for accommodating items. When the rotation angle of the door body 200 is in the range from 90° to the maximum angle, the user can fully pull out the drawer. And because H2 < H1, in order to make the width of the drawer can be set wider, the intrusion amount H2 when the relative angle between the door body 200 and the main body 100 is the largest is used as a reference to set the width of the drawer. The width of the drawer setting range is the width of the main body 100 minus H2. When taking items, open the door body 200 to the maximum angle, and the drawer can be pulled out normally.

[0173] Please refer to Figures 20 - 23 , in some embodiments, when the relative angle between the door body 200 and the main body 100 is the largest, the distance A3 between the first shaft 311 and the front wall 210 is 7mm to 17mm, the distance B3 between the first shaft 311 and the side wall 220 is 4.5mm to 14.5mm, the distance C3 between the second shaft 312 and the front wall 210 is 21mm to 31mm, and the distance D3 between the second shaft 312 and the side wall 220 is 4mm to 14mm.

[0174] When the door body 200 rotates to the maximum angle, the distances between the first shaft 311 and the second shaft 312 and the front wall 210 and the side wall 220 are still small, that is, the movement trajectories of the first shaft 311 and the second shaft 312 are relatively compact. Since the first shaft 311 slides in the first slot 321 and the second shaft 312 slides in the second slot 322, the arrangements of the first slot 321 and the second slot 322 are also correspondingly relatively compact, thereby reducing the occupied space of the hinge assembly 300, and further enabling the thickness of the door body 200 to be thinner, meeting the ultra-thin door requirement of the refrigeration device 10.

[0175] Specifically, the maximum angle of the door body 200 relative to the main body 100 can be 120°, so that the opening degree of the door body 200 is large, facilitating the user to take items. And, the distance A3 between the first shaft 311 and the front wall 210 can be 8mm, 10mm, 12mm, 14mm, 16mm, the distance B3 between the first shaft 311 and the side wall 220 can be 5.5mm, 7.5mm, 9.5mm, 11.5mm, 13.5mm, the distance C3 between the second shaft 312 and the front wall 210 can be 22mm, 24mm, 26mm, 28mm, 30mm, and the distance D3 between the second shaft 312 and the front wall 210 can be 23mm, 25mm, 27mm, 29mm, 30mm.

[0176] In some embodiments, when the relative angle between the door body 200 and the main body 100 is the largest, the distance L6 between the first edge 221 and the main body 100 is 20mm to 30mm

[0177] Since the door body 200 and the main body 100 are connected by the sliding fit between the first shaft 311 and the first slot 321, and the second shaft 312 and the second slot 322, that is, a dynamic connection. If the distance between the door body 200 and the main body 100 is too far, the connection between the door body 200 and the main body 100 will be unstable. Therefore, the distance between the door body 200 and the main body 100 is limited to make the connection more stable.

[0178] Specifically, when the relative angle between the door body 200 and the main body 100 is the largest, the distance L6 between the door body 200 and the main body 100 can be 21mm, 23mm, 25mm, 27mm, 29mm.

[0179] In some embodiments, when the relative angle between the door body 200 and the main body 100 is the largest, the distance L7 between the door body 200 and the cabinet body 20 is greater than 0.3mm.

[0180] When the relative angle between the door body 200 and the main body 100 is at its maximum, the front wall 210 of the door body 200 is close to the cabinet body 20. The distance between the door body 200 and the cabinet body 20 represents the shortest distance between the front wall 210 and the cabinet body 20. Since the door body 200 is most likely to interfere with the edge of the cabinet body 20 during the opening process, the shortest distance between the front wall 210 and the cabinet body 20 is the X-direction distance between the front wall 210 and the edge of the cabinet body 20.

[0181] When the user takes an item, the door needs to be opened to the maximum angle. When the relative angle between the door body 200 and the main body 100 is at its maximum, the overhang of the door body 200 is the largest and it is most likely to interfere with the cabinet body 20. In the embodiment of the present application, since the overhang of the door body 200 is reduced, when the relative angle between the door body 200 and the main body 100 is at its maximum, there is also a gap between the door body 200 and the cabinet body 20, and the distance is greater than 0.3 mm, thereby greatly improving the situation where the door body 200 is likely to interfere with the cabinet body 20.

[0182] Specifically, when the relative angle between the door body 200 and the main body 100 is at its maximum, the distance L7 between the door body 200 and the cabinet body 20 can be 0.4 mm, 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm.

[0183] In some embodiments, when the relative angle between the door body 200 and the main body 100 is at its maximum, the distance W3 in the thickness direction of the door body 200 between the axis of the first shaft 311 and the axis of the second shaft 312 is 8 mm to 20 mm.

[0184] When the relative angle between the door body 200 and the main body 100 is at its maximum, the distance in the Y direction between the axis of the first shaft 311 and the axis of the second shaft 312 is short, that is, the movement trajectories of the first shaft 311 and the second shaft 312 are relatively compact, and the distance between the first shaft 311 and the second shaft 312 always remains short. Since the first shaft 311 slides in the first groove 321 and the second shaft 312 slides in the second groove 322, the arrangements of the first groove 321 and the second groove 322 are also relatively compact accordingly. Thus, on the premise of ensuring the rotation angle of the door body 200, the thickness of the door body 200 in the Y direction can be made thinner to improve the aesthetics and save space.

[0185] Specifically, the distance W3 in the thickness direction of the door body 200 between the axis of the first shaft 311 and the axis of the second shaft 312 can be 9 mm, 11 mm, 13 mm, 5 mm, 17 mm.

[0186] In some embodiments, when the relative angle between the door body 200 and the main body 100 is at its maximum, the included angle α3 between the connection line of the axis of the first shaft 311 and the axis of the second shaft 312 and the front wall 210 is less than 85°.

[0187] The included angle between the axis connection line of the first shaft 311 and the second shaft 312 and the front wall 210 represents the distance between the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200. The smaller the included angle between the axis connection line of the first shaft 311 and the second shaft 312 and the front wall 210, the closer the distance between the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200 when the first shaft 311 is located at the first end point 321a. Compared with the middle position of the first shaft 311 and the second shaft 312 in the thickness direction of the door body 200, the closer the first shaft 311 and the second shaft 312 are to the front wall 210, so that the first shaft 311 and the second shaft 312 can have more movement space during the door opening process, and the thickness of the door body 200 can be reduced when arranging hinge assemblies 300 with the same opening angle.

[0188] Specifically, when the relative angle between the door body 200 and the main body 100 is the largest, the included angle α3 between the connection line of the axis of the first shaft 311 and the axis of the second shaft 312 and the front wall 210 can be 80°, 81°, 82°, 83°, 84°.

[0189] In some embodiments, the over-box amount of the door body 200 is less than 1 mm. The over-box amount is the distance that the door body 200 moves towards the cabinet body 20 during the process of the door body 200 rotating from the closed state to the state where the relative angle with the main body 100 is the maximum angle. Limiting the over-box amount to a smaller value can prevent the door body 200 from squeezing the cabinet body 20.
