Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to a door assembly of an embedded refrigeration device and the embedded refrigeration device. Background Art

[0002] In today's society, the rapid progress of science and technology has greatly promoted the transformation of home lifestyles. Among them, built-in furniture, as a design concept that combines beauty and practicality, is favored by consumers. By cleverly integrating electrical appliances or storage space into the home environment, built-in furniture not only effectively saves space, but also significantly improves the overall coordination and aesthetics of the home. Take the built-in refrigerator as an example. This design allows the refrigerator to be seamlessly embedded in the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, although the built-in refrigerator has shown significant advantages in improving home aesthetics and space utilization, there is still a problem that cannot be ignored in its actual use: the door is prone to interfere or collide with the side wall of the cabinet during opening, resulting in a poor user experience of the built-in refrigerator. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the related art. To this end, the present invention provides a door assembly of a refrigeration device, which can control the gap on the door opening side of the door assembly while preventing interference.

[0004] The invention also provides an embedded refrigeration device.

[0005] A door assembly of an embedded refrigeration device according to an embodiment of the first aspect of the present invention includes:

[0006] The door is rotatably connected to the refrigeration box, wherein the refrigeration box is used to be embedded in the accommodation space formed by the installation body;

[0007] A door panel is movably mounted on the box door, wherein the door panel has a first interference position, and the first interference position is located at an inner corner of the door opening side of the door panel;

[0008] The controller is configured as:

[0009] When the width of the door panel is less than the critical width value, during the process of opening the door, before the first interference position leaves the accommodation space, the door panel is controlled to start moving toward the door opening side of the door;

[0010] When the width of the door panel is not less than the critical width value, during the process of opening the door, before the first interference position leaves the accommodation space, the door panel is stationary relative to the door, and after the first interference position leaves the accommodation space, the door panel is controlled to start moving toward the door opening side of the door;

[0011] The critical width value is determined by the structural parameters of the door panel and the box door.

[0012] According to the embedded refrigeration device of the embodiment of the present invention, the cabinet door is stationary before the first interference position leaves the accommodating space, which means that in this case, when the cabinet door is in the closed position, the distance between the door panel and the side wall corresponding to the accommodating space can be zero, thereby achieving zero gap on the opening side of the door body assembly, thereby ensuring the aesthetic appearance of the embedded refrigeration device equipped with such a door body assembly.

[0019] According to one embodiment of the present invention, the controller is configured as follows:

[0021] When the width of the door panel satisfies Δθ0<Δθx, when the opening angle of the door reaches Δθx, the door body is controlled to move toward the door opening side of the door.

[0067] In today's society, the rapid progress of science and technology has greatly promoted the transformation of home lifestyles. Among them, built-in furniture, as a design concept that combines beauty and practicality, is favored by consumers. By cleverly integrating electrical appliances or storage space into the home environment, built-in furniture not only effectively saves space, but also significantly improves the overall coordination and aesthetics of the home. Take the built-in refrigerator as an example. This design allows the refrigerator to be seamlessly embedded in the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, although the built-in refrigerator has shown significant advantages in improving home aesthetics and space utilization, there is still a problem that cannot be ignored in its actual use: the door is prone to interfere or collide with the side wall of the cabinet during opening, resulting in a poor user experience of the built-in refrigerator.

[0068] Specifically, when the built-in refrigerator (referring to refrigerator) satisfies the user's requirements for two different types of refrigerators, namely, pure flat and fully embedded and fully embedded, the entire door assembly will be thickened after the refrigerator door body (referred to as box door) is connected to the cabinet door panel (referred to as door panel), causing the door assembly with the cabinet door to interfere with the cabinet during the process of opening and closing the door, after the refrigerator is pushed into the storage space of the cabinet, relying only on the original single-axis or double-axis structural hinges of the refrigerator, resulting in the inability to open and use the door normally. Therefore, the present application proposes a door assembly that can enable the box door and the door panel to slide relative to each other, so that in the process of opening the door assembly, the door panel can slide toward the side of the door opening (that is, the door opening side), so that in the process of opening the door, the hinge side still maintains the thickness of the box door itself, which is consistent with the door opening scene without a door panel; in the process of closing the door, the door panel will move toward the hinge side to return to the state before the door is opened; thereby achieving the embedded installation requirements of the refrigerator with or without a door panel.

[0069] For aesthetic reasons, the gap between the door panels of the same row of cabinets is usually within the range of 0mm-5mm. Therefore, this method and structure of sliding the door panel relative to the cabinet door is necessary to solve the interference problem between the movable door panel and the adjacent cabinet panels within the initial small angle range. As the cabinet door is opened, the door panel moves relative to the cabinet door. If the displacement of the door panel corresponding to each degree of the cabinet door opening is too large, the door panel will interfere with the cabinet panel adjacent to the door opening side when the door panel width is small (the smaller the door panel width, the greater the rotation angle required for the door panel to get rid of the interference of the adjacent cabinet panel on the corresponding door opening side). If the displacement of the corresponding angle is too small, the door panel may interfere with the cabinet panel adjacent to the hinge side. That is, if the width of the door panel is different, the relative movement relationship between the door panel and the cabinet door is also different in order to avoid interference between the door panels.

[0070] Based on this, the present application proposes a door assembly for an embedded refrigeration device, referring to Figures 1 to 4 , including a door 2, a door panel 9 and a controller (not shown in the figure). Among them, the door 2 can be rotatably connected to the refrigeration box body 1, and the refrigeration box body 1 is used to be embedded in the accommodating space formed by the installation body. The installation body here generally refers to the cabinet 6. Of course, the installation body can also be a wall corner, or the installation body can also refer to other components, as long as a accommodating space can be formed. The following description is based on the installation body being the cabinet 6 as an example. The door panel 9 is movably installed on the door 2, and the door panel 9 has a first interference position, and the first interference position is located at the inner corner of the door opening side of the door panel 9. The "inside" is relative to the refrigeration box body. The side facing the refrigeration box body 1 is the "inside" side, and on the contrary, the side facing away from the refrigeration box body 1 is the "outside" side. The controller can be installed on the door 2 or the door panel 9 of the door body. Of course, the controller can also be installed on the refrigeration box body 1. The controller is configured as follows: when the width of the door panel 9 is less than the critical width value, during the process of opening the door 2, before the first interference position leaves the accommodating space, the door panel 9 is controlled to start moving toward the door opening side of the door 2; when the width of the door panel 9 is not less than the critical width value, during the process of opening the door 2, before the first interference position leaves the accommodating space, the door panel 9 is stationary relative to the door 2, and after the first interference position leaves the accommodating space, the door panel 9 is controlled to start moving toward the door opening side of the door 2; wherein the critical width value is determined by the structural parameters of the door panel 9 and the door 2.

[0071] According to an embodiment of the present application, the door 2 is stationary before the first interference position leaves the accommodating space, which means that in this case, when the door 2 is in the closed position, the distance between the door panel 9 and the side wall corresponding to the accommodating space can be zero, thereby achieving zero gap on the opening side of the door panel 9 assembly, thereby ensuring the aesthetic appearance of the embedded refrigeration equipment equipped with this door body assembly.

[0072] Figures 2 to 4 In the figure, the position relationship and angle relationship of the refrigerator when the door is not initially opened and when the door 2 is opened to any angle (indicated by the dotted line in the figure) are simplified and annotated. The corners that may interfere during the door opening and closing process are marked with black dots in the figure, where point C represents the inner corner point of the left end of the door panel 9, which is the first interference position. The first interference position is the point where interference will occur with the end face of the first cabinet panel 601 adjacent to the left side during the door opening and closing process; point e represents the outer corner point of the right end of the cabinet panel, which is the critical point for point C of the door panel 9 to escape interference during the door opening and closing process. The situation where point c escapes interference at the critical point e corresponds to the situation where the first interference position is about to leave the accommodating space, that is, the situation where the first interference position point C is flush with point e of the cabinet 6, that is, the situation where the interference position point c is located on the horizontal line where point e is located. Point d represents the outer corner point of the right end of the door panel 9, which is the second interference position, which is the corner point where the right end face of the door panel 9 first interferes with the left end face of the second cabinet panel 602 adjacent to the right side during the door opening and closing process. Combined with Figures 2 to 4 ,because Figures 2 to 4 is a top view, the first interference position and the second interference position are from Figures 2 to 4 If the inner corner of the door opening side is in an arc shape, the first interference position is the point on the arc segment farthest from the hinge axis 101 of the door 2. Similarly, if the outer corner of the hinge side is in an arc shape, the second interference position is the point on the arc segment farthest from the hinge axis 101 of the door 2.

[0073] According to the embodiment of the present application, for the case where the width of the door panel 9 is relatively large, that is, not less than the critical width value, when the first interference position of the door panel 9 leaves the accommodation space, the opening angle of the corresponding door 2 is still relatively small, so the hinge side of the door panel 9 will not interfere. Therefore, before the first interference position of the door panel 9 leaves the accommodation space, the door panel 9 can be stationary relative to the door 2 to ensure that both sides of the door panel 9 do not interfere with the cabinet 6. Among them, the critical width value can be 450mm to 550mm. For example, when the critical width value is 500, the width of the door panel 9 is in the range of 300mm to 500mm, and the width of the door panel 9 is considered to be relatively small; when the width of the door panel 9 is in the range of 500 to 800, the width of the door panel 9 is considered to be relatively large. Similarly, when the critical width value is 510 mm, it is considered that the width of the door panel 9 is small when the value range is between 300 mm and 510 mm; when the width of the door panel 9 is between 510 and 800 mm, it is considered that the width of the door panel 9 is large. Of course, the width of the door panel 9 is not limited to between 300 mm and 800 mm, and may have other values.

[0074] Combination Figures 2 to 4When the door 2 is in the closed position, the gap between the door panel 9 and the first cabinet panel 601 on the left (i.e., the side wall of the accommodating space corresponding to the door panel 9 on the door opening side) is δ1, and δ2 is the distance between the end face of the hinge side of the door panel 9 and the cabinet panel on the right (i.e., the side wall of the accommodating space corresponding to the door panel 9 on the hinge side). The hinge axis 101 of the hinge 10 of the door 2 is point O in the figure. l1 is the vertical distance from the hinge axis 101 of the door 2 to the inner surface of the door panel 9, l2 is the vertical distance from the hinge axis 101 of the door 2 to the end face of the door panel 9 on the door opening side, l3 is the vertical distance from the hinge axis 101 of the door 2 to the end face of the door panel 9 on the hinge side, and h is the thickness of the door 2.

[0075] from Figures 2 to 4 It can be seen that in the initial position, on the left side of the hinge axis 101, the angle between the hypotenuse OCo between point C and the hinge axis 101 and the inner side of the door panel 9 is θ0. The angle when the door 2 is opened to any position is Δθ0, and the hypotenuse OCo, distance l2 and distance l1 at this position are represented by black dotted lines; it is assumed that on the right side of the hinge axis 101, the distance l3 from the right end face of the door panel 9 of different widths to the hinge axis 101 (i.e. point o) on this side remains unchanged.

[0076] When the width of the door panel 9 increases to l21, assuming that the box door 2 is opened to an angle Δθ1, the intersection of the horizontal line of point C and the corner point e on the right side of the door panel 9 is C1, and the hypotenuse OC1 and the distance l21 at this position are represented by blue dotted lines.

[0077] When the width of the door panel 9 is reduced to l22, assuming that the door 2 is opened to an angle Δθ2, the intersection of point C and the horizontal line where the corner point e on the right side of the door panel 9 is located is C2, and the hypotenuse OC2 and the distance l22 at this position are represented by red dotted lines.

[0078] On the right side of the hinge axis 101, the hypotenuse between point d and the hinge axis 101 is od. When the door 2 is opened to any position with an angle of Δθ, the hypotenuse odx, the distance l1+h and the distance l3 at that position are indicated by black dotted lines. Figures 2 to 4 It can be seen that during the opening process of the door 2, if the door panel 9 does not move along the door 2 toward the door opening side, as the opening angle Δθ increases, the point dx will soon interfere with the left end surface of the second cabinet panel 602, causing the door 2 to be unable to open. The horizontal distance between the point dx on the door panel 9 at this position and the right end surface of the door panel 9 at the initial position is set to λ, that is, λ is the vertical distance that the second interference position moves toward the side wall of the corresponding storage space.

[0079] It can be seen on the left side of the hinge axis 101 that by comparing the sizes of the door opening angles Δθ1, Δθ0 and Δθ2 corresponding to the intersections C1, C0 and C2 of the horizontal line passing through the right end of the second cabinet board 602 and the outer corner point e on the left side of the door panel 9 of different widths, it can be seen that the larger the width of the door panel 9, the smaller the rotation angle of the point C on the door panel 9 to get rid of the right end of the left side of the adjacent first cabinet board 601 during the door opening and closing process. That is, the smaller the width of the door panel 9, the larger the rotation angle required to get rid of the interference of the adjacent cabinet board on the left side. According to this rule, it can be known that during the door opening process, when the door panel 9 slides toward the door opening side relative to the box door 2, its total sliding amount Δs corresponds to the door body rotation angle Δθ. If the door panel 9 starts to move from the initial position relative to the box door 2, the movement amount Δs of the door panel 9 increases with the increase of the door opening angle Δθ. Therefore, it can be known that when the width of the door panel 9 is too small, since the angle at which point C on the door panel 9 escapes interference becomes larger at this time, the corresponding displacement Δs of the door panel 9 will become larger, but the gap δ1 between the door panel 9 and the first cabinet panel 601 on the left is certain. Therefore, for the case where the width of the door panel 9 is smaller, when designing the corresponding sliding mechanism (which will be introduced in detail later, connected between the door panel 9 and the box door 2, and used to realize the movement of the door panel 9 relative to the box door 2), it is necessary to consider that within the initial rotation range (for example, 0°-15°), the corresponding displacement Δs cannot be too large. At the same time, if the displacement Δs is too small, the dx point on the door panel 9 on the hinge side will quickly interfere with the second cabinet panel 602 adjacent to the right.

[0080] Assuming that during the process of opening the door, when the door body is opened at an angle of Δθ, the angle between the hypotenuse of the point dx and the hinge axis 101 and the horizontal line in the figure is set to β, and the angle between the hypotenuse of the point C and the hinge axis 101 (that is, point o) and the horizontal line in the figure is set to α. That is, β is the angle between the vertical line between the second interference position of the door panel 9 and the intersection of the door 2 and the width direction of the storage space, and α is the angle between the vertical line between the first interference position and the hinge axis of the door 2 and the width direction of the storage space when the first interference position is about to leave the storage space without sliding relative to the door 2. Let the horizontal distance between the point C and the left end face of the initial position of the door panel 9 at this time be γ, that is, γ is the vertical distance that the first interference position moves toward the side wall of the corresponding storage space.

[0081] According to the embodiment of the present application, the critical width value can be obtained in the following manner: Specifically, the critical width value satisfies: Δθ0 = Δθx.

[0082] Δθ0 is calculated as follows:

[0083]

[0084] Among them, combined Figures 2 to 4, Δθ0 is the angle of the door 2 when the first interference position moves to the point where it is about to leave the accommodation space, when the door panel 9 does not slide relative to the door 2. Obviously, α can be obtained from get.

[0085] Δθx is calculated as follows:

[0086]

[0087] In the above, l1, l3, δ2 and h are all known and are specific constants, and l2 is a variable value.

[0088] From δ2, it is possible to obtain the maximum rotation angle Δθx of the door 2 corresponding to the case where the door panel 9 does not move relative to the door 2 at the initial position and the hinge side of the door panel 9 does not interfere with the second cabinet panel 602.

[0089] The above Δθ0 and Δθx can both be expressed by a function of l2, and then l2 at this time, that is, the critical width value, can be obtained by Δθ0=Δθx.

[0090] It is worth mentioning that the critical width value is not limited to being calculated using the above formula. In some cases, for example, adding a correction coefficient or correction value to the above formula can also be used to calculate the critical width value. In addition, the above calculation formula is for the case where the hinge axis 101 is determined. If the door 2 is installed using a double-axis hinge or a movable hinge, the hinge axis 101 will change as the door 2 is opened, and the calculation formula for the critical width value will also change adaptively. The formula needs to calculate the moving distance of the hinge axis 101. In addition, if there is an installation gap between the door panel 9 and the door 2, then h in the above calculation formula is the distance between the sliding surface of the door panel 9 and the outer surface of the door panel 9, and l1 is the distance from the hinge point of the door 2 to the sliding surface of the door panel 9.

[0091] According to an embodiment of the present application, the controller is configured as follows: when the width of the door panel 9 satisfies Δθ0≥Δθx, the width of the door panel 9 is relatively small, and when the opening angle of the box door 2 is Δθ<Δθx, the door panel 9 is stationary relative to the box door 2, and during the process of Δθ0≥Δθ≥Δθx, the door body is controlled to move toward the opening side of the box door 2.

[0092] During the movement of the door panel 9 relative to the cabinet door 2 , the moving distance Δs≤γ+δ1 is ensured to avoid interference between the opening side of the door panel 9 and the first cabinet panel 601 .

[0093] in,

[0094] Or, during the movement of the door panel 9 relative to the door 2, ensure that This is to avoid interference between the open side of the door panel 9 and the first cabinet panel 601 .

[0095] The controller is further configured to: when the width of the door panel 9 satisfies Δθ0<Δθx, the width of the door panel 9 is relatively large, and when the opening angle of the cabinet door 2 reaches Δθx, the door body is controlled to move toward the door opening side of the cabinet door 2. Before this, the door panel 9 is stationary relative to the cabinet door 2 to ensure that the door panel 9 does not interfere with the cabinet 6. That is, before the first interference position leaves the accommodation space, the door panel 9 does not need to move toward the door opening side of the cabinet door 2, and it can still be ensured that the hinge side of the door panel 9 does not interfere with the second cabinet panel 602.

[0096] During the movement of the door panel 9 relative to the door 2, ensure β-l3, to ensure that the hinge side of the door panel 9 does not interfere with the second cabinet panel 602.

[0097] According to an embodiment of the present application, the critical width value is 450 mm to 550 mm.

[0098] According to an embodiment of the present application, the door panel 9 is movably mounted on the box door 2 through the sliding mechanism 4; the sliding mechanism 4 has an engaged state and a disengaged state, and the box door 2 has a state switching angle; in the process of the box door 2 switching from the closed position to the state switching angle, the sliding mechanism 4 is in a disengaged state, and the door panel 9 is stationary relative to the box door 2; in the process of the box door 2 switching from the state switching angle to the maximum opening angle, the sliding mechanism 4 is in an engaged state, and the sliding mechanism 4 drives the door panel 9 to move toward the opening side of the box door 2.

[0099] According to the door body assembly of the embodiment of the present application, the door panel 9 can prevent the door panel 9 from sliding relative to the door 2 when the door is initially opened at a small angle, thereby avoiding interference on the opening side of the door panel 9. When the door panel 9 is rotated to a certain angle and does not interfere with the cabinet panels on both sides, the door panel 9 can slide relative to the door 2 at a larger displacement, thereby quickly avoiding the adjacent wooden board on the hinge side. This type of door body assembly has a wider range of application scenarios and fewer usage restrictions, and is suitable for scenarios where the door panel 9 is small in width or the door panel 9 has a large displacement per degree of door opening.

[0100] The state switching angle may be set to the Δθx mentioned above.

[0101] According to the door assembly of the embodiment of the present application, its door closing process is also a reverse process of the door opening process. Specifically, during the door closing process, the sliding mechanism 4 is first in a combined state, and then the door 2 is closed to drive the door panel 9 to move toward the hinge side of the door 2. Until the door opening angle of the door 2 corresponds to the state switching angle, the sliding mechanism 4 is in a disengaged state, at which time the door panel 9 has been reset, and then as the door 2 is further closed, the cabinet door no longer moves relative to the door 2. Since the door panel 9 is reset in advance, as the door 2 gradually approaches the closed position, the door panel 9 will not interfere with the cabinet 6.

[0102] According to an embodiment of the present application, the state switching angle ranges from 0° to 5°, for example, 4.15°. Corresponding to this state switching angle, the gap value between the two sides of the door body assembly and the accommodating space in the closed position can be kept to a minimum to ensure the aesthetics and safety of the door body assembly. Among them, corresponding to the state switching angle, if the door opening side of the door panel 9 has left the accommodating space, then in this case, the distance between the door opening side of the door body assembly in the closed position and the side wall of the corresponding accommodating space (that is, the cabinet panel of the cabinet 6) can be zero or close to zero.

[0103] The door panel 9 has an interference position, which is located at the outer corner of the hinge side of the door panel 9. If the outer corner of the door panel 9 has an arc, the interference position is the vertical line in the arc area that is farthest from the hinge axis of the door. Corresponding to the state switching angle, the distance between the interference position of the door panel 9 and the accommodating space and its corresponding side wall (that is, the cabinet panel corresponding to the interference position) is 0mm to 0.3mm. The cabinet door 2 is at the state switching angle, which corresponds to the situation that the hinge side of the door panel 9 and the cabinet panel are about to interfere. If the door panel 9 is still stationary relative to the cabinet door 2 at this time, as the cabinet door 2 is further opened, the door panel 9 will hit the cabinet panel. The ideal state is that the distance between the interference position and the side wall is exactly equal to zero at the corresponding state switching angle, but in order to ensure safe use, a certain safety margin can be reserved, and then as the cabinet door 2 is opened to the state switching angle, there is still a very small distance between the interference position of the door panel 9 and the cabinet panel.

[0104] See also Figure 5 In addition to the sliding mechanism 4, a driven component 3 may be provided between the door panel 9 and the door 2 to ensure the smooth movement of the door panel 9. Figures 6 to 8 The driven component 3 includes a first track 301 and a first moving part 302 that can slide relative to the first track 301. Figure 6 The first track 301 and the first moving part 302 may adopt the structure of a slide rail and a slider. Fig. 9, the first track 301 may be in the form of a rack 406, and the first moving part 302 may be a gear 407 meshed with the rack 406. The specific structural forms of the first track 301 and the first moving part 302 are not limited, as long as the first moving part 302 can move along the first track 301.

[0105] According to one of the embodiments of the present application, see Fig.10 The sliding mechanism 4 includes a base (not marked), the base is provided with a second track 401 and a third track 402; a second moving part 403 and a third moving part 404, the second moving part 403 can be slidably mounted on the second track 401, the third moving part 404 can be slidably mounted on the third track 402, and the third moving part 404 is connected to the door panel 9; a connecting member 408 (combined with Figure 6 ) are connected to the second moving part 403 and the third moving part 404 at both ends, the traction mechanism 5 drives the second moving part 403 to move along the second track 401, and the second moving part 403 drives the third moving part 404 to move along the third track 402 through the connecting member 408, and the moving directions of the second moving part 403 and the third moving part 404 are opposite. The connecting member 408 can be a steel wire rope, or can also be other components that can realize power transmission between the second moving part 403 and the third moving part 404.

[0106] Of course, the specific structure of the sliding mechanism 4 is not limited to the example given here, as long as the traction mechanism 5 drives the sliding mechanism 4 to move, the door panel 9 can be moved relative to the door 2. For example, the sliding mechanism 4 can be a structure of double slide rails and sliders mentioned above, or a structure in which a gear 407 and a rack 406 cooperate, etc. Fig. 9 The sliding mechanism 4 includes a gear 407 and a rack 406, and the rack 406 is driven to move by rotating the driving gear 407, wherein the gear 407 is connected to the output shaft of the traction mechanism 5, and the rack 406 is fixedly connected to the door panel 9.

[0107] According to the embodiments of the present application, Figure 6, the traction mechanism 5 includes a pull rod 501 and a motor, the first end of the pull rod 501 is rotatably connected to the second moving part 403, and the second end of the pull rod 501 is rotatably connected to the box door 2. In order to delay the sliding mechanism 4 to drive the door panel 9 to move during the door opening process, one of the first end of the pull rod 501 and the second moving part 403 is provided with a first pin 502, and the other is provided with a first long hole (not marked in the figure). Then, through the cooperation between the first pin 502 and the first long hole, the door panel 9 is delayed to move when the door is opened. Alternatively, one of the second end of the pull rod 501 and the box door 2 is provided with a second pin 503, and the other is provided with a second long hole (not marked in the figure). Then, through the cooperation between the second pin 503 and the second long hole, when the box door 2 is just opened, the second pin 503 and the second long hole cannot achieve motion transmission until the second pin 503 contacts the side wall of the second long hole, at which time the motion of the traction mechanism 5 is transmitted to the sliding mechanism 4, thereby driving the door panel 9 to move relative to the box door 2. On the basis of the above, the motor power is coupled to the first end of the pull rod 501 to drive the pull rod 501 to rotate.

[0108] In addition to the above long hole (i.e., the first long hole or the second long hole) and the pin structure, a limiting portion can also be provided on the third moving portion 404. In the disengaged state, the limiting portion and the door panel 9 are spaced apart, and in the engaged state, the door panel 9 and the limiting portion are in contact. Figure 6 The third moving part 404 is provided with a notch 303, the limiting part is the end side wall of the slide slot, and the third moving part 404 also includes a hook 304, which is hung on the notch 303. In the engaged state, the hook 304 abuts against the end side wall of the notch 303. Then, as the traction mechanism 5 drives the second moving part 403 to move, the third moving part 404 moves with the door panel 9 relative to the box door 2. In the above, the opening width of the notch 303 is greater than the width of the hook 304, so as to ensure that the hook 304 and the side wall of the notch 303 do not contact each other in the disengaged state.

[0109] In another embodiment, the connecting member 408 is a flexible cable, which is tightened in the engaged state and relaxed in the disengaged state. For example, a tensioning component may be provided, and the state of the sliding mechanism 4 is switched by switching the position of the tensioning component, so that before the flexible cable is tightened, the movement of the second moving part 403 cannot be transmitted to the third moving part 404 until the flexible cable is tightened, at which time the traction mechanism 5 can drive the third moving part 404 to move through the second moving part 403, and then the third moving part 404 drives the door panel 9 to move.

[0110] In yet another embodiment, see Fig.11The traction mechanism 5 includes an arc gear 504 and a motor. The arc gear 504 has a toothed portion; the second moving portion 403 is provided with a rack 406. In the engaged state, the rack 406 and the toothed portion are meshed, and in the disengaged state, the rack 406 and the arc gear 504 are separated; the motor power is coupled to the arc gear 504 to drive the arc gear 504 to rotate.

[0111] Of course, in order to achieve delayed movement of the door panel 9, the specific type of the sliding mechanism 4 is not limited to the above examples.

[0112] According to an embodiment of the present application, an embedded refrigeration device is provided, including a refrigeration box body 1 and a door assembly, wherein the refrigeration box body 1 is suitable for being embedded in a receiving space, and the door assembly is installed on the refrigeration box body 1.

Of course, the number and distribution positions of the sliding mechanism 4 and the driven assembly 3 are not limited by the example. Among them, the door panel 9 is fixedly connected with a hook 304, and the hook 304 can be hung in the notch 303 of the sliding mechanism 4 or the driven assembly 3. The driven assembly 3 is fixed in the middle of the lower end cover 8, and the notches 303 at both ends of the driven assembly 3 at the bottom are hung with the corresponding hooks 304. The driven assembly 3 includes a first track 301 and a first moving part 302 that slides along the first track 301. Both the upper end cover 7 and the lower end cover 8 have an avoidance opening that avoids the entire travel of the hook 304 to ensure that the door panel 9 can reciprocate relative to the box door 2.

[0114] Figure 5 and Figure 6 In the embodiment, the main body of the sliding mechanism 4 and the upper end cover 7 are fixed together, the side of the sliding mechanism 4 close to the box body is connected with a pull rod 501 through a hinge shaft, and the other end of the pull rod 501 is fixed to the box body through a hinge shaft, and the sliding mechanism 4 includes a base, a second track 401 and a third track 402, the second track 401 and the third track 402 can be arranged up and down, a second moving part 403 is arranged on the second track 401, and a third moving part 404 is arranged on the third track 402, the second track 401 is hinged with the pull rod 501 through a fixed seat, and the third moving part 404 on the third track 402 is provided with a notch 303 that can be hung with a door panel 9. The second moving part 403 and the third moving part 404 are connected together by a steel wire rope, which can play a role in the synchronous reverse movement of the second moving part 403 and the third moving part 404.
