[0002] For an embedded refrigerator, it is preferred that the front wall of the door body of the refrigerator is flush with the front end of the cabinet after the embedded refrigerator is embedded in the cabinet, so that the refrigerator and the cabinet are integrated and the overall effect is beautified. However, during the rotation and opening of the door body, the side edge located at the front end of the pivoting side of the door body protrudes towards the cabinet. When the gap between the refrigerator and the cabinet is small, the side edge interferes with the cabinet, affecting the opening of the door body.

[0003] Therefore, it is necessary to provide a new refrigeration device to solve the above problems. SUMMARY

[0004] The present application relates to the field of refrigeration equipment, and particularly relates to a refrigeration device capable of controlling the movement track of a door body during the opening of the door body.

[0005] To achieve the above-mentioned application purposes, the present application adopts the following technical solutions: a refrigeration device, comprising a cabinet, a door body, a hinge assembly connecting the door body to the cabinet, the cabinet having a pivoting side connected to the hinge assembly, the door body having a side edge at one end of the side wall of the pivoting side away from the cabinet, the hinge assembly having a hinge shaft arranged on one of the cabinet and the door body, and a hinge slot arranged on the other one to cooperate with the hinge shaft; the direction of the center of the door body in the closed state towards the pivoting side is the first direction, and the direction of the center of the door body in the closed state away from the pivoting side is the second direction; while the door body is rotating and opening, the hinge shaft and the hinge slot move relative to each other, driving the door body to move first towards the second direction, then rotate in place to the side edge located on the side of the hinge shaft close to the cabinet, and then the door body moves towards the first direction.

The first section, the second section, and the third section are arranged in the direction from the starting position to the end position and are sequentially connected. During the opening of the door body, the guide shaft moves from the starting position to the end position. During the movement of the guide shaft from the first section to the second section, the hinge shaft moves from the first position to the first end relative to the hinge slot. During the movement of the guide shaft from the second section to the third section, the hinge shaft remains at the first end. During the movement of the guide shaft from the third section to the end position, the hinge shaft moves from the first end to the second end relative to the hinge slot.

[0013] As a further improved technical solution of the present application, the guide slot further comprises a fourth section connecting the starting position and one end of the first section away from the second section. During the movement of the guide shaft from the fourth section to the first section, the hinge shaft remains at the first position.

[0014] As a further improved technical solution of the present application, the hinge groove comprises a pivot groove in communication with the second end, the guide groove further comprises a transition section in communication with the third section, a fifth section in communication with the transition section and the terminal position, when the guide shaft moves from the third section to the fifth section through the transition section, the hinge shaft is driven to move from the second end to the pivot groove; during the movement of the guide shaft to the terminal position in the fifth section, the hinge shaft remains in the pivot groove.

[0015] The present application has the following advantages: the refrigeration device in the present application drives the door body to move towards the second direction first, and then rotates in place to the side edge located on the side of the hinge shaft close to the cabinet, and then the door body moves towards the first direction, which can avoid interference between the door body and the cabinet during opening, increase the opening degree of the door body, avoid the door body from interfering with the storage compartment or the drawer in the cabinet, and facilitate the user to take and place the articles.

[0021] The present application will be described in detail below with reference to the embodiments shown in the drawings, which should be referred to Figures 1-5The embodiments shown are preferred embodiments of the present application. It should be noted that these embodiments are not intended to limit the present application, and equivalent changes or substitutions in function, method, or structure made by those of ordinary skill in the art based on these embodiments are within the scope of the present application. In various views of the present application, certain dimensions of structures or parts are exaggerated relative to other structures or parts for ease of illustration, and thus only serve to illustrate the basic structure of the subject matter of the present application.

[0022] Please refer to Figures 1-5 As shown, the top view shows the door body 2 of the refrigeration device in the present application being opened to different angles. In the present application, the refrigeration device is an embedded refrigerator 100, and the refrigerator 100 is embedded in a cabinet. It can be understood that the refrigerator 100 is not necessarily embedded in a cabinet, but can also be embedded in a wall, or the refrigerator 100 is a non-embedded refrigerator 100. At the same time, the refrigeration device is not limited to the refrigerator 100, but can also be a wine cabinet, etc.

[0023] The refrigerator 100 includes a cabinet 1, a door body 2 for opening and closing the cabinet 1, and a hinge assembly 3 for pivotally connecting the door body 2 to the cabinet 1.

[0024] It should be emphasized that the hinge assembly 3 in the present embodiment is not only applicable to the refrigerator 100, but also applicable to other scenarios, such as cabinets, wine cabinets, wardrobes, etc. The present application takes the refrigerator 100 as an example for illustration, but is not limited thereto.

[0025] One side of the refrigerator 100 on the left and right sides where the hinge assembly 3 is arranged is a pivot side 4. The direction in which the center of the door body 2 in the closed state is defined as the first direction, and the direction in which the center of the door body 2 in the closed state is away from the pivot side 4 is defined as the second direction.

[0026] Specifically, when the hinge assembly 3 is arranged on the right side of the refrigerator 100, the first direction is from left to right, and the second direction is from right to left. When the hinge assembly 3 is arranged on the left side of the refrigerator 100, the first direction is from right to left, and the second direction is from left to right.

[0027] The door body 2 has a side wall 21 in the closed state located on the pivot side 4, and one end of the side wall 21 away from the cabinet 1 forms a side edge 22 when the door body 2 is in the closed state.

[0028] In the embodiment, the hinge assembly 3 has a hinge shaft 31 arranged on one of the cabinet 1 and the door body 2, a hinge groove 32 arranged on the other one to cooperate with the hinge shaft 31, a guide shaft 33 arranged on one of the cabinet 1 and the door body 2, and a guide groove 34 arranged on the other one to cooperate with the guide shaft 33. When the door body 2 rotates to open, the guide shaft 33 moves relative to the guide groove 34, and drives the hinge shaft 31 to move relative to the hinge groove 32 along a preset path, so as to drive the door body 2 to translate and move along a preset track. Of course, the hinge shaft 31 is not limited to move relative to the hinge groove 32 along a preset path. In other embodiments, other driving structures or guide structures can be arranged to drive the hinge shaft 31 to move relative to the hinge groove 32 along a preset path.

[0029] That is, the hinge shaft 31, the hinge groove 32, the guide shaft 33 and the guide groove 34 can have various distribution positions. In a first example, the hinge shaft 31 and the guide shaft 33 are arranged on the cabinet 1, and the hinge groove 32 and the guide groove 34 are arranged on the door body 2. In a second example, the hinge shaft 31 and the guide shaft 33 are arranged on the door body 2, and the hinge groove 32 and the guide groove 34 are arranged on the cabinet 1. In a third example, the hinge shaft 31 and the guide groove 34 are arranged on the cabinet 1, and the hinge groove 32 and the guide shaft 33 are arranged on the door body 2. In a fourth example, the hinge shaft 31 and the guide groove 34 are arranged on the door body 2, and the hinge groove 32 and the guide shaft 33 are arranged on the cabinet 1.

[0030] Here, the first example is taken as an example, that is, the hinge shaft 31 and the guide shaft 33 are arranged on the cabinet 1, and the hinge groove 32 and the guide groove 34 are arranged on the door body 2. It can be understood that, at this time, during the rotation of the door body 2, the hinge groove 32 and the guide groove 34 move, so that the hinge shaft 31 moves relative to the hinge groove 32, and the guide shaft 33 moves relative to the guide groove 34.

[0031] Further, in a specific embodiment, the hinge assembly 3 includes a hinge plate 35 fixed to the cabinet 1 and a guide block 36 fixed to the door body 2, that is, the hinge shaft 31 and the guide shaft 33 are arranged on the hinge plate 35, and the hinge groove 32 and the guide groove 34 are arranged on the guide block 36. Of course, the hinge groove 32 and the guide groove 34 are not limited to be directly recessed on the door body 2 in other embodiments.

[0032] In the present application, the preset track of the door body 2 includes: when the door body 2 rotates to open, the hinge shaft 31 moves relative to the hinge groove 32, drives the door body 2 to move first towards the second direction, and then rotates in place to the side edge 22 being located on the side of the hinge shaft 31 close to the cabinet 1, and then the door body 2 moves towards the first direction.

[0033] Specifically, in combination with Figure 2 As shown in the figure, in the process that the door body 2 rotates to open from the first opening angle to the second opening angle, the door body 2 moves towards the second direction, that is, the door body 2 moves away from the cabinet located on the pivot side 4, which can increase the distance between the door body 2 and the cabinet, and prevent interference between the door body 2 and the cabinet during opening.

[0034] In combination with Figure 3 As shown in the figure, in the process that the door body 2 continues to open from the second opening angle to the third opening angle, the door body 2 rotates in place, so that the side edge 22 is located on the side of the hinge shaft 31 close to the cabinet 1. It can be known that when the door body 2 rotates to the side edge 22 and the hinge shaft 31 are at the same distance from the cabinet 1, the side edge 22 protrudes the maximum distance in the first direction, at this time, if the door body 2 is driven to move in the first direction, the side edge 22 is more likely to interfere with the cabinet. Therefore, before the door body 2 moves in the first direction, it is rotated in place to the side edge 22 being located on the side of the hinge shaft 31 close to the cabinet 1, that is, the distance between the side edge 22 and the cabinet 1 is less than the distance between the hinge shaft 31 and the cabinet 1, at this time, the side edge 22 will be retracted in the second direction by a distance, which can provide a certain allowance for the subsequent movement of the door body 2 in the first direction, so that the door body 2 can move a greater distance in the first direction, and further increase the opening degree of the door body 2.

[0035] Specifically, the third opening angle is less than 90°.

[0036] In combination with Figure 4 As shown in the figure, in the process that the door body 2 continues to open from the third opening angle to the fourth opening angle, the door body 2 moves towards the first direction, which can further increase the opening degree of the door body 2, avoid that the door body 2 shields the storage compartment in the cabinet 1 or the drawer in the cabinet 1 from being opened due to interference of the door body 2, and facilitate the user to take and place articles.

[0037] Further, the extension direction of the hinge groove 32 is arranged as follows: when the door body 2 moves towards the second direction, the door body 2 moves towards the cabinet 1, so that the center of gravity of the door body 2 approaches the cabinet 1 during opening, which can avoid the door body 2 from falling.

[0038] Further, the extending direction of the hinge slot 32 is arranged such that when the door body 2 moves towards the first direction, the door body 2 moves towards the direction of the cabinet 1, so that the center of gravity of the door body 2 is close to the cabinet 1 during the opening process, and the door body 2 can be prevented from falling.

[0039] Specifically, please refer to Figure 1 As shown in the embodiment in which the hinge slot 32 is arranged on the door body 2, the hinge slot 32 includes a first end 321, a second end 322 arranged opposite to the first end 321, and a first position 323 between the first end 321 and the second end 322, the hinge slot 32 extends from the first end 321 towards the cabinet 1 and the side wall 21 away from the pivot side 4 to the second end 322. When the door body 2 is in the closed state, the hinge shaft 31 is located at the first position 323. As Figure 2 As shown in the embodiment in which the hinge shaft 31 moves from the first position 323 to the first end 321 relative to the hinge slot 32, the door body 2 is driven to move towards the second direction; as Figure 4 As shown in the embodiment in which the hinge shaft 31 moves from the first end 321 to the second end 322 relative to the hinge slot 32, the door body 2 is driven to move towards the first direction.

[0040] The centers of the first end 321, the second end 322 and the first position 323 are located on the same straight line, so as to facilitate the movement of the hinge shaft 31 between the first end 321, the second end 322 and the first position 323. The center of different positions in the present application refers to the intersection of the center axis of the hinge shaft 31 or the guide shaft 33 located at the position and the plane towards the side of the hinge plate 35.

[0041] It can be understood that, as Figure 1 As shown in the embodiment in which the door body 2 is at the first opening angle, the hinge slot 32 extends from the first position 323 towards the side wall 21 and away from the cabinet 1 to the first end 321. When the door body 2 is translated, the hinge shaft 31 moves from the first position 323 to the first end 321, the door body 2 moves towards the second direction and towards the cabinet 1. As Figure 4As shown, during the process that the door body 2 is opened from the third opening angle to the fourth opening angle, the hinge groove 32 extends from the first end 321 to the second end 322 in the first direction and away from the cabinet 1. During the process that the door body 2 is translated and the hinge shaft 31 is moved from the first end 321 to the second end 322 relative to the hinge groove 32, the door body 2 is moved in the first direction and towards the cabinet 1. Of course, this is not limited, and in other embodiments, the extension direction of the hinge groove 32 can be adjusted according to specific needs.

[0042] Correspondingly, the guide groove 34 has a starting position 341, an end position 342, a first section 343 between the starting position 341 and the end position 342, a second section 344, and a third section 345. The first section 343, the second section 344, and the third section 345 are arranged in the direction from the starting position 341 to the end position 342 and are sequentially connected. During the process that the door body 2 is opened, the guide shaft 33 is moved from the starting position 341 to the end position 342.

[0043] In combination Figure 2 As shown, during the process that the door body 2 is rotated from the first opening angle to the second opening angle, the guide shaft 33 is moved in the second section 344 from the first section 343 to the third section 345, driving the hinge shaft 31 to move from the first position 323 to the first end 321 relative to the hinge groove 32, so that the door body 2 is translated in the second direction and towards the cabinet 1.

[0044] In combination Figure 3 As shown, during the process that the door body 2 is rotated from the second opening angle to the third opening angle, the guide shaft 33 is moved in the third section 345 from the second section 344 to the end position 342. At this time, the hinge shaft 31 is kept at the first end 321, so that the door body 2 is rotated in place around the hinge shaft 31.

[0045] In combination Figure 4 As shown, during the process that the door body 2 is rotated from the third opening angle to the fourth opening angle, the guide shaft 33 is moved in the third section 345 from the second section 344 to the end position 342, driving the hinge shaft 31 to move from the first end 321 to the second end 322 relative to the hinge groove 32, so that the door body 2 is translated in the first direction and towards the cabinet 1.

[0046] Specifically, in the embodiment where the guide slot 34 and the hinge slot 32 are both arranged on the door body 2, the second end 322 is close to the guide slot 34, and the first end 321 is away from the guide slot 34 relative to the second end 322. Along the extension direction from the starting position 341 to the terminal position 342, the first section 343 gradually approaches the hinge slot 32, so that when the guide shaft 33 moves along the first section 343 in the direction of the terminal position 342, the hinge shaft 31 can be driven to move from the first position 323 to the first end 321 away from the guide slot 34, so as to drive the door body 2 to translate in the second direction and towards the cabinet 1.

[0047] The second section 344 is a circular arc with the first end 321 as the center, so that when the guide shaft 33 moves along the second section 344, the hinge shaft 31 remains at the first end 321, and the door body 2 rotates around the hinge shaft 31.

[0048] Meanwhile, along the extension direction from the starting position 341 to the terminal position 342, the third section 345 gradually moves away from the hinge slot 32, so that when the guide shaft 33 moves along the third section 345 in the direction of the terminal position 342, the hinge shaft 31 can be driven to move from the first end 321 to the second end 322, so as to drive the door body 2 to translate in the first direction and towards the cabinet 1.

[0049] Further, please refer to Figure 1 As shown, in a specific embodiment, the first opening angle is greater than 0°, and during the process of opening the door body 2 from the closed state to the first opening angle, the door body 2 rotates in place. Of course, it is not limited thereto, and in other embodiments, the first opening angle can also be set to 0°, that is, when the door body 2 is opened from the closed state, it directly moves in the second direction while rotating.

[0050] It can be known that when the door body 2 is in the closed state, the door seal on the door body 2 is tightly adsorbed on the cabinet 1, so that when the door body 2 is opened from the closed state, rotating the door body 2 in place by the first opening angle can make the door seal first separate from the cabinet 1, so as to prevent the door seal from being deformed and damaged, affecting the subsequent sealing performance of the door body 2. Correspondingly, in the last stage of closing the door, the door body 2 rotates in place to the closed state, which can also reduce the deformation of the door seal, and is beneficial to the smooth closing of the door body 2.

[0051] Meanwhile, for the refrigerator 100 with the turnover beam, the door body 2 rotates in place when opening from the closed state, which can make the turnover beam turn over and disengage from the guide structure on the cabinet 1, so that the door body 2 can continue to rotate and open. Correspondingly, in the process of rotating in place to close in the last stage, the turnover beam can be guided by the guide structure on the cabinet 1 to turn over to shield the gap between the left and right door bodies 2.

[0052] Specifically, the guide groove 34 further includes a fourth segment 346 connected to the first segment 343 and away from one end of the second segment 344, and the fourth segment 346 is a circular arc with the center of the first position 323 as the center. In the process of moving the guide shaft 33 in the fourth segment 346, the hinge shaft 31 remains in the first position 323, and the door body 2 rotates in place.

[0053] It can be understood that the size of the first opening angle can be set according to specific conditions, and the length of the fourth segment 346 is matched with the first opening angle.

[0054] Further, in combination with Figure 5 As shown in the drawings, after the door body 2 is opened to the fourth opening angle, i.e., after the door body 2 moves towards the first direction, the door body 2 continues to rotate in place to increase the opening angle of the door body 2, which is convenient for users to take and place articles.

[0055] In a specific embodiment, the hinge groove 32 further includes a pivot groove 324 connected to the second end 322, and the guide groove 34 further includes a transition segment 347 connected to the third segment 345, a fifth segment 348 connected to the transition segment 347 and the terminal position 342, and when the guide shaft 33 moves from the third segment 345 to the fifth segment 348 through the transition segment 347, the hinge shaft 31 is driven to move from the second end 322 to the pivot groove 324; in the process of moving the guide shaft 33 in the fifth segment 348 to the terminal position 342, the hinge shaft 31 remains in the pivot groove 324, and the door body 2 rotates in place. The line connecting the center of the pivot groove 324 and the center of the second end 322 intersects the line connecting the center of the first end 321, the second end 322 and the first position 323, which can solve the problem of side sliding or sliding of the door body 2 caused by the fact that the fifth segment 348 is parallel to the hinge groove 32. Of course, it is not limited thereto, and in other embodiments, when the door body 2 is opened to the fourth opening angle and continues to open, it can also be set to rotate in place around the hinge shaft 31 located at the second end 322.

[0056] Specifically, the fifth segment 348 is a circular arc with the center of the pivot groove 324 as the center.

[0057] The door 2 of the refrigerator 100 in the present application opens as follows:

[0058] In combination Figure 1 As shown, in the process that the door 2 is opened from the closed state to the first opening angle, the door 2 rotates in place, at this time, the guide shaft 33 moves in the first section 343 towards the direction where the second section 344 is located, and the hinge shaft 31 remains in the first position 323.

[0059] In combination Figure 2 As shown, in the process that the door 2 is opened from the first opening angle to the second opening angle, the door 2 moves towards the second direction and approaches the cabinet 1, at this time, the guide shaft 33 moves in the second section 344 towards the direction where the third section 345 is located, and the hinge shaft 31 moves from the first position 323 to the first end 321 relative to the hinge groove 32.

[0060] In combination Figure 3 As shown, in the process that the door 2 is opened from the second opening angle to the third opening angle, the door 2 rotates in place to the side edge 22 located at the rear side of the hinge shaft 31, at this time, the guide shaft 33 moves in the second section 344 towards the direction where the third section 345 is located, and the hinge shaft 31 remains in the first end 321.

[0061] In combination Figure 4 As shown, in the process that the door 2 is opened from the third opening angle to the fourth opening angle, the door 2 moves towards the first direction and approaches the cabinet 1, at this time, the guide shaft 33 moves in the third section 345 towards the direction where the transition section 347 is located, and the hinge shaft 31 moves from the first end 321 to the second end 322 relative to the hinge groove 32.

[0062] In combination Figure 5 As shown, in the process that the door 2 is continuously opened from the fourth opening angle, the door 2 rotates in place, at this time, the guide shaft 33 switches to the fifth section 348 through the transition section 347 and moves towards the terminal position 342, and the hinge shaft 31 remains in the pivot groove 324.

[0063] In summary, the refrigeration device in the application, when the door body 2 rotates and opens, the hinge shaft 31 moves relative to the hinge groove 32, drives the door body 2 to move first towards the second direction, then rotates in place to the side edge 22 located on the side of the hinge shaft 31 close to the cabinet 1, and then the door body 2 moves towards the first direction, which can avoid interference between the door body 2 and the cabinet during opening, can increase the opening degree of the door body 2, avoid that the door body 2 shields the storage compartment in the cabinet 1 or the drawer in the cabinet 1 cannot be opened due to the interference of the door body 2, and is convenient for users to take and place articles.
