Technical Field

[0003] The present application relates to the field of refrigeration technology, and in particular to a door assembly of an embedded refrigeration device and an embedded refrigeration device. Background Art

[0004] In today's society, rapid technological advancements have significantly driven changes in home lifestyles. Built-in furniture, a design concept that combines aesthetics with practicality, has gained widespread popularity among consumers. By cleverly integrating appliances or storage spaces into the home, built-in furniture not only effectively saves space but also significantly enhances the overall harmony and aesthetics of the home. For example, a built-in refrigerator allows it to be seamlessly integrated into the cabinetry, blending seamlessly with the kitchen decor and creating a modern and harmonious living environment. However, despite their significant advantages in enhancing home aesthetics and space utilization, built-in refrigerators still present a significant practical issue: the door can easily interfere with or collide with the cabinet sidewalls when opened, resulting in a poor user experience. Summary of the Invention

[0005] The present application proposes a door assembly for refrigeration equipment, which can solve the problems of interference and collision of door assemblies and improve user experience.

[0006] The present application also proposes an embedded refrigeration device.

[0007] The door assembly of the embedded refrigeration device according to an embodiment of the present application includes:

[0008] The door is rotatably connected to a refrigeration box of the refrigeration equipment, and the refrigeration box is used to be embedded in the accommodation space formed by the installation body;

[0009] Sliding mechanism;

[0010] A door panel is connected to the door via the sliding mechanism and moves relative to the width direction of the door;

[0011] The door has a critical door opening angle, which is smaller than the maximum door opening angle;

[0012] During the process of the box door rotating from the closed position to the critical door opening angle, the sliding mechanism drives the door panel to move relative to the box door, and the moving distance Δs is not less than the critical safety distance corresponding to the critical door opening angle; the critical safety distance is the minimum sliding distance required for the door panel to not interfere with the outside world during the process of the box door rotating from the closed position to the maximum opening angle; during the process of the box door rotating from the critical door opening angle to the maximum door opening angle, the door panel is stationary relative to the box door.

[0013] According to the door assembly of the embedded refrigeration appliance of the embodiment of the present application, during the opening process of the door assembly, the door panel stops sliding relative to the door before reaching the maximum opening angle. That is, during the latter part of the door opening process, the door panel is stationary relative to the cabinet door. This can improve the stability of the door assembly structure, make the movement of the door panel more concealed, and reduce the user's concern about the door panel falling off. In addition, because the larger the opening angle of the door assembly, the closer it is to the user, the door panel stops sliding in advance, which can reduce the noise impact during the door opening process and improve the user experience.

[0018] According to one embodiment of the present application, the critical safety distance further satisfies: after the second interference position leaves the accommodating space, there is a gap between the second interference position and the panel of the installation body.

[0019] According to one embodiment of the present application, the critical door opening angle is between 1° and 105°.

[0020] According to one embodiment of the present application, the maximum door opening angle is between 90° and 135°.

[0021] According to one embodiment of the present application, the sliding mechanism includes:

[0024] a third movable portion, slidably mounted on the third track, the third movable portion being connected to the door panel;

[0025] A connecting member has one end connected to the second moving part and the other end connected to the third moving part.

[0026] According to one embodiment of the present application, the connecting member includes:

[0027] a first flexible cable, passing around one end of the base, with both ends connected to one end of the second movable part and one end of the third movable part respectively;

[0030] A refrigeration box body, adapted to be embedded in the accommodation space;

[0031] The above-mentioned double-door assembly.

[0032] A method for controlling a door assembly of an embedded refrigeration appliance according to an embodiment of the present application includes:

[0033] Determining a critical safety distance of the door assembly when rotating relative to the refrigeration cabinet based on dimensional parameters of the door assembly, wherein the refrigeration cabinet of the refrigeration equipment is adapted to be embedded in the accommodating space formed by the mounting body, the cabinet door of the door assembly is adapted to be rotatably connected to the refrigeration cabinet, the door panel of the door assembly is movably mounted on the cabinet door, and the door panel is movable along the width direction of the cabinet door, and the critical safety distance is the minimum sliding distance required for the door panel to not interfere with the outside world during the process of the cabinet door rotating from the closed position to the maximum opening angle;

[0053] In today's society, rapid technological advancements have significantly driven changes in home lifestyles. Built-in furniture, a design concept that combines aesthetics with practicality, has gained widespread popularity among consumers. By cleverly integrating appliances or storage spaces into the home, built-in furniture not only effectively saves space but also significantly enhances the overall harmony and aesthetics of the home. For example, a built-in refrigerator allows it to be seamlessly integrated into the cabinetry, blending seamlessly with the kitchen decor and creating a modern and harmonious living environment. However, despite their significant advantages in enhancing home aesthetics and space utilization, built-in refrigerators still present a significant practical issue: the door can easily interfere with or collide with the cabinet sidewalls when opened, resulting in a poor user experience.

[0054] Specifically, when a built-in refrigerator (referred to as refrigerator) meets the user's needs for two different types of refrigerators, namely, pure flat fully embedded and fully embedded, the refrigerator door body (referred to as box door) will be connected to the cabinet door panel (referred to as door panel), causing the entire door body assembly to become thicker. As a result, after the refrigerator is pushed into the storage space of the cabinet, the door body assembly with the cabinet door will interfere with the cabinet during the process of opening and closing the door, relying only on the original single-axis or double-axis structural hinges of the refrigerator, resulting in an inability to open and use it normally.

[0055] Therefore, the present application proposes a door body assembly (referred to as door body assembly) that can enable relative sliding between the box door and the door panel, so that in the process of opening the door body assembly, the door panel can slide toward the side where the door is opened (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 and return to the state before the door was opened; thereby, the embedded installation requirements of the refrigerator can be achieved with or without a door panel.

[0056] If the door panel and the refrigerator door continue to slide relative to each other, when the door is opened at a large angle, the door panel will slide a large distance, causing users to panic and worry that the door panel will fall off, affecting the user experience. This worry is particularly evident when the refrigerator is fully loaded or the refrigerator is tall. Based on this, the application further proposes a door body assembly for embedded refrigeration equipment, which can solve the door panel interference problem. When the refrigerator door is opened to a certain angle, the door panel stops moving relative to the refrigerator door, thereby improving the user experience.

[0057] Please refer to Figures 1 and 2. The door assembly includes a door 2, a sliding mechanism 4 and a door panel 9. Among them, the door 2 can be rotatably connected to the refrigeration box 1 of the refrigeration equipment, and the refrigeration box 1 is used to be embedded in the accommodation 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 an accommodation space can be formed. The following description takes the installation body as the cabinet 6 as an example. The door panel 9 is connected to the door 2 through the sliding mechanism 4 and moves in the width direction relative to the door 2. The door 2 has a critical door opening angle, which is less than the maximum door opening angle of the door 2. In the process of the door 2 rotating from the closed position to the critical door opening angle, the sliding mechanism drives the door panel 9 to move relative to the door 2. In the process of the door 2 rotating from the critical door opening angle to the maximum door opening angle, the door panel 9 is stationary relative to the door 2. Among them, in the process of the box door 2 rotating from the closed position to the critical door opening angle, the movement distance Δs of the door panel 9 needs to ensure that the door panel 9 does not interfere with the entire door opening process. Therefore, the movement distance Δs is not less than the critical safety distance; the critical safety distance is the minimum sliding distance required for the door panel 9 to not interfere with the outside world during the process of the box door 2 rotating from the closed position to the maximum opening angle.

[0058] According to an embodiment of the present application, during the opening process of the door assembly, before reaching the maximum opening angle, the door panel 9 stops sliding relative to the door 2. That is, during the latter part of the door opening process, the door panel 9 is stationary relative to the door 2. This can improve the stability of the door assembly structure, make the movement of the door panel 9 more concealed, and reduce the user's concern about the door panel 9 falling off. In addition, since the larger the angle of the door assembly is opened, the closer it is to the user, the door panel 9 stops sliding in advance, which can reduce the noise impact during the door opening process and improve the user experience.

[0059] According to an embodiment of the present application, the range of the critical safety distance may be determined in a variety of different ways.

[0060] In one embodiment, if the maximum opening angle of the door assembly is 90 degrees, then, to ensure that the door assembly does not interfere, a necessary condition is that, when the door 2 is opened 90 degrees, there is a mounting gap d2 between the door panel 9 and the cabinet 6 panel. The cabinet 6 panel is the second cabinet panel 602 in the figure, and the first cabinet panel 601 also belongs to the cabinet 6 panel. To ensure that the mounting gap d2 exists between the door panel 9 and the cabinet 6 panel when the door 2 is opened 90 degrees, the movement distance of the door panel 9 relative to the door 2 is L2-L1=c+d2+{x-(ab)+d3+h}. Furthermore, as long as the movement distance Δs is no less than L2-L1, the door panel 9 does not interfere with the outer surface of the second cabinet panel 602 when the door 2 is opened to 90 degrees. The mounting gap d2 is generally greater than zero. However, in extreme cases, the mounting gap d2 can also be zero, so that when the door 2 is opened to 90 degrees, the door panel 9 does not contact the second cabinet panel 602.

[0061] Among them, L2=y+c+d2, L1=y-{x-(ab)+d3+h}, L2-L1=c+d2+{x-(ab)+d3+h}.

[0062] Among them, y is the width of the door 2, c is the difference in width between the door panel 9 and the door 2 (not marked in the figure, and some parameters later are not marked in the figure), d2 is the assembly gap reserved between the cabinet door and the panel of the installation body when the door 2 is opened to the maximum opening angle, x is the thickness of the door 2, a is the longitudinal wheelbase of the door 2, that is, the distance from the inner surface of the door 2 to the hinge axis 101 of the door 2 when the door 2 is closed, b is the transverse wheelbase of the door 2, that is, the distance from the end face of the hinge side of the door 2 to the hinge axis 101 of the door 2 when the door 2 is closed, d3 is the assembly gap between the door 2 and the cabinet door, and h is the thickness of the cabinet door.

[0063] According to an embodiment of the present application, when the assembly gap d3 between the box door 2 and the cabinet door is 6 mm and the thickness h of the door panel 9 is 23 mm, the total thickness of the door body assembly is x+d3+h=x+29.

[0064] When the door panel 9 is opened to 90°, the door 2 extends beyond the edge line L1 of the cabinet 6 by y-{x-(ab)+d3+h}. When the lateral wheelbase b of the door 2 is 12.5 mm, L1=y-{x-(a-12.5)+6+23}=y-x+a+41.5.

[0065] When the door panel 9 is opened to 90°, the door panel 9 extends beyond the edge line L2 of the cabinet 6 by y+c+d2. When the width difference c between the door panel 9 and the box door 2 is equal to 8mm, and the box door 2 is opened to the maximum opening angle, the assembly gap d2 reserved between the cabinet door and the panel of the installation body is 5mm. At this time, y+c+d2=y+13.

[0066] When the door panel 9 is opened to 90 degrees, the distance that the door panel 9 extends beyond the cabinet door 2 is L2-L1=y+13-(y-x+a+41.5)=x+a+54.5, where the units in the above formula are all millimeters.

[0067] That is, when the cabinet door moves relative to the refrigerator door 2 by a distance Δs reaching x+a+54.5, it can achieve non-interference with the second cabinet panel 602 throughout the entire 90° door opening process. The earlier this distance is achieved during the door opening process, the better the user experience. That is, the sliding of the refrigerator door 2 and the door panel 9 only occurs at the beginning of the door opening. Subsequently, as the door angle increases, the load and bearing feeling of the refrigerator door 2 gradually increase. At this time, the refrigerator door 2 and the door panel 9 no longer slide relative to each other, which increases the sense of stability of the refrigerator.

[0068] Based on the above requirements, the embodiments of the present application use motion simulation or formula calculations to derive the parameters of the sliding mechanism. If the sliding mechanism is implemented by a connecting rod, the connecting rod length and initial angle can be calculated. If the sliding mechanism is implemented by a gear transmission, the number of gear teeth and pressure angle can be calculated. This allows the refrigerator door 2 and door panel 9 to slide relative to each other when the refrigerator is just opened, and then stop sliding relative to each other at a certain angle. That is, when the refrigerator door 2 is fully opened, the door 2 and door panel 9 are in a relatively static state, thereby improving the user experience.

[0069] Taking the sliding mechanism as an example, let the connecting rod length be m and the initial angle be α. Based on Adams motion simulation or theoretical calculation, we can derive the displacement values ​​corresponding to different door opening angles when the connecting rod length and initial angle are certain values. Simply find the door opening angle corresponding to the aforementioned relative sliding distance value to find the corresponding connecting rod length and initial angle value. Beyond this angle, the door panel 9 and the door 2 will no longer slide relative to each other. Similarly, the opposite is true when closing the door: that is, when the door 2 and the door panel 9 are initially closed, there is no relative sliding, and only when they reach a certain angle do they begin to slide until they are completely closed. Taking a refrigerator door 2 with a width of 595mm, a longitudinal wheelbase of 47mm, and a transverse wheelbase of 14mm as an example, when the connecting rod length is 77mm and the initial angle is 14.5°, the displacement relationship is shown in Table 1. Based on the distance that the door panel 2 of this refrigerator door 2 ultimately needs to extend beyond the refrigerator door 2, the corresponding parameters are searched in the table. That is, when the critical safety distance that the door panel 9 needs to extend beyond the refrigerator door 2 is 61mm, a 50° door opening can be achieved, and the subsequent 40° door opening does not require relative sliding. Based on parameters such as the actual door thickness, the connecting rod parameters can be adjusted to reduce the door opening angle at which sliding stops.

[0070] In another embodiment, in order to determine the critical safety distance, the first interference position and the second interference position on the door panel 9 where interference is most likely to occur can be determined first, and based on the fact that the first interference position and the second interference position never interfere with the accommodating space, the value range of the critical safety distance can be obtained.

[0071] Referring to Figures 4 to 6 , according to an embodiment of the present application, the door panel 9 has a first interference point c and a second interference point d. The first interference point is located at the inner corner of the door panel 9 on the door opening side, and the second interference point is located at the outer corner of the door panel 9 on the hinge side. The terms "inside" and "outside" are relative to the refrigeration cabinet 1, with the side facing the refrigeration cabinet 1 being the "inside" side and the side facing away from the refrigeration cabinet 1 being the "outside" side. Since Figure 4 is a top view, the first and second interference points appear as a single point. It can be understood that, for the door assembly, the first and second interference points are each a vertical line. If the inner corner of the door opening side is arc-shaped, the first interference point is the point on the arc segment farthest from the hinge axis 101 of the door 2. Similarly, if the outer corner of the door panel 9 on the hinge side is arc-shaped, the second interference point is the point on the arc segment farthest from the hinge axis 101 of the door 2. Among them, the critical safety distance satisfies: before the first interference position leaves the accommodation space, there is a gap between the first interference position and the corresponding side wall of the accommodation space; when the second interference position leaves the accommodation space, there is a gap between the second interference position and the corresponding side wall of the accommodation space.

[0072] 4 to 6 , when the door 2 is closed, the distance between the end face of the door panel 9 on the opening side and the side wall corresponding to the accommodating space is δ1, and the distance between the end face of the door panel 9 on the hinge side and the side wall corresponding to the accommodating space is δ2.

[0073] δ1 is not less than the movement distance γ of the first interference position along the width direction of the accommodating space before the first interference position leaves the accommodating space, γ is also the vertical distance that the first interference position moves toward the side wall of the corresponding accommodating space. δ2 is not less than the movement distance λ of the second interference position along the width direction of the accommodating space before the second interference position leaves the accommodating space, λ is also the vertical distance that the second interference position moves toward the side wall of the corresponding accommodating space, that is, δ1≥γ, δ2≥λ. "Before the first interference position leaves the accommodating space" corresponds to the situation before the first interference position point c is aligned with the point e of the cabinet 6, that is, the situation where the interference position point c is located before the horizontal line where point e is located. "Before the second interference position leaves the accommodating space" corresponds to the situation before the second interference position point d is aligned with the point f of the cabinet 6, that is, the situation where the interference position point d is located before the horizontal line where point f is located.

[0074] Generally, δ1>γ and δ2>λ are required, although extreme cases where δ1=γ and δ2=λ are not excluded. When the door 2 is closed, the width of the door 2 is aligned with the width of the storage space. As the door 2 opens, an angle forms between the width of the door 2 and the width of the storage space.

[0075] According to an embodiment of the present application, assuming that the door panel 9 moves a distance Δs, the length of the side where point c and the hinge axis 101 (that is, point o) are located is set to a, and the angle between it and the horizontal line in the figure is set to α. At this time, the length of the side where point d and the hinge axis 101 (that is, point o) are located is set to b, and the angle between it and the horizontal line in the figure is set to β.

[0076] In Figures 2 to 4, the position relationship and angular relationship of the refrigeration equipment (refrigerator) when the door is initially closed and when the door 2 is opened to any angle (indicated by the dotted lines in the figures) are simplified and annotated. The corners where interference may occur during the door opening process are marked with black dots in the figures. Among them, the first interference position c is likely to interfere with the point e on the right side of the first cabinet panel 601. That is, point e is the critical point at which point c escapes interference (leaves the accommodation space) during the door opening and closing process. The second interference position d is the corner point on the right side of the door panel 9. It 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 during the door opening and closing process. As can be seen from the figure, in the initial position, on the left side of the hinge axis 101, the angle between the hypotenuse oc between point c and the hinge axis 101 (point o) and the inner side of the door panel is θ0, and the angle when the door 2 is opened to any position is Δθ. At this position, the hypotenuse oc, the distance l2 and the distance l1 are represented by dotted lines; in the initial position, 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 od, the distance l1+h and the distance l3 are represented by dotted lines; as can be seen from the figure, during the opening process of the door 2, if the door panel does not move along the door 2 toward the door opening side, as the opening angle increases, point d will soon interfere with the left end face of the second cabinet panel 602, causing the door 2 to be unable to open. Therefore, in order to avoid interference affecting the door opening, it is necessary to move the corresponding door panel 9 toward the door opening side when the door body opening angle is Δθ during the door opening process.

[0077] In one embodiment, δ1≥γ=a×cosα−l2.

[0078] in,

[0079] As mentioned above, Δθ is the angle of rotation of the door 2 during the opening process, and Δs is the distance that the door panel 9 moves relative to the door opening side of the door 2 during the opening process.

[0080] In one embodiment, δ2≥λ=b*cosβ-l3.

[0081] in,

[0082] Therefore, when l1, l2, l3, h, δ1 and δ2 are all determined, the value range of Δs can be obtained.

[0083] The above formula for calculating Δs does not constitute a restriction on Δs. For example, the above formula can also have a correction coefficient or correction parameter. In addition, the above formula is determined for the case where the hinge axis 101 is determined. If the door 2 is installed with a biaxial hinge or a movable hinge, the hinge axis 101 will change as the door 2 is opened, and the calculation formula of Δs will also change adaptively. The formula needs to calculate the movement 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 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.

[0084] Wherein, δ1 and δ2 generally do not exceed 5 mm. For example, when δ1=δ2=4 mm, the value range of Δs can be obtained.

[0085] According to an embodiment of the present application, the critical door opening angle is between 1° and 105°. That is, when the door 2 is opened to the critical opening angle, the door panel 9 no longer slides relative to the door 2, thereby ensuring the stability of the door assembly structure and improving the user experience.

[0086] According to an embodiment of the present application, the maximum door opening angle is between 90° and 135°.

[0087] According to an embodiment of the present application, referring to FIG7 , in addition to the sliding mechanism 4 provided between the door panel 9 and the box door 2, a driven assembly 3 may also be provided to ensure the smooth movement of the door panel 9. In conjunction with FIG7 to FIG9 , the driven assembly 3 includes a first track and a first movable portion that can slide relative to the first track. The first track and the first movable portion in FIG7 may adopt the structural form of a slide rail and a slider. Alternatively, referring to FIG8 , the first track may be in the form of a rack 406 in the sliding mechanism 4, and in this case, the first movable portion may be a gear 407 engaged with the rack 406. The specific structural form of the first track and the first movable portion is not limited here, as long as the first movable portion can move along the first track.

[0088] According to one embodiment of the present application, please refer to Figure 9, 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 movable part 403 and a third movable part 404, the second movable part 403 can be slidably installed on the second track 401, the third movable part 404 can be slidably installed on the third track 402, and the third movable part 404 is connected to the door panel 9; the second movable part 403 and the third movable part 404 are connected at both ends of the connecting member respectively, the traction mechanism drives the second movable part 403 to move along the second track 401, and the second movable part 403 drives the third movable part 404 to move along the third track 402 through the connecting member, and the moving directions of the second movable part 403 and the third movable part 404 are opposite.

[0089] According to an embodiment of the present application, the connecting member can be a flexible cable, such as a steel wire rope, or can be other components that can realize power transmission between the second movable part 403 and the third movable part 404. In addition, the second rail 401 and the third rail 402 can both adopt the structural form of a slide rail, in which case the second movable part 403 and the third movable part 404 can both adopt the structural form of a slider. Of course, the specific structural form of the second rail 401, the third rail 402, the second movable part 403 and the third movable part 404 is not limited by the examples given here, as long as the second movable part 403 slides along the second rail 401 and the third movable part 404 moves along the third rail 402.

[0090] According to an embodiment of the present application, the connecting member may include a first flexible cable and a second flexible cable. The first flexible cable passes around one end of the base, with both ends connected to one end of the second movable portion 403 and the third movable portion 404, respectively. The second flexible cable passes around the other end of the base, with both ends connected to the other ends of the second movable portion 403 and the third movable portion 404, respectively.

[0091] The specific structure of the sliding mechanism 4 is not limited by the examples given herein, as long as the traction mechanism 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 the structure of the double slide rails and sliders mentioned above, or can be a structure in which a gear 407 and a rack 406 cooperate. Referring to FIG6 , the sliding mechanism 4 includes a gear 407 and a rack 406. The gear 407 is driven to rotate and drive the rack 406 to move, wherein the gear 407 is connected to the output shaft of the traction mechanism, and the rack 406 is fixedly connected to the door panel 9.

[0092] According to an embodiment of the present application, during the opening process of the door body assembly, the door panel stops relative to the box door in advance before rotating to the maximum door opening angle.

[0093] In one case, the movement of the door panel is controlled by a motor. For example, the motor drives the sliding mechanism to move the door body relative to the box door. In this case, the controller can control the start and stop of the motor to achieve the desired effect.

[0094] Alternatively, the movement of the door panel relative to the door is driven by a mechanical structure. Specifically, a suitable sliding mechanism can be selected to ensure that the sliding mechanism has both engaged and disengaged states. In the engaged state, the door panel is driven by the sliding mechanism to move relative to the door; in the disengaged state, the door panel remains stationary relative to the door. Specifically, before the door panel moves a distance Δs that reaches a critical safety distance, the sliding mechanism is engaged; after that, the sliding mechanism is disengaged.

[0095] For example, referring to Figure 10 , the traction mechanism includes an arc-shaped gear 504 and a motor. The arc-shaped gear 504 has teeth, and the second movable portion 403 is provided with a rack 406. In the engaged state, the rack 406 meshes with the teeth, and in the disengaged state, the rack 406 and the arc-shaped gear 504 are separated. The motor is coupled to the arc-shaped gear 504 to drive the arc-shaped gear 504 to rotate. Of course, to achieve the switching between the engaged and disengaged states, the specific type of the sliding mechanism 4 is not limited to the above example.

[0096] According to an embodiment of the present application, an embedded refrigeration device is provided, including a refrigeration box body 1 and a door assembly. 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.

[0097] According to an embodiment of the present application, a method for controlling a door assembly of an embedded refrigeration appliance is provided, comprising:

[0098] Step 10: Determine a critical safety distance of the door assembly when rotating relative to the refrigeration cabinet based on dimensional parameters of the door assembly, wherein the refrigeration cabinet of the refrigeration equipment is adapted to be embedded in the accommodation space formed by the mounting body, the cabinet door of the door assembly is adapted to be rotatably connected to the refrigeration cabinet, the door panel of the door assembly is movably mounted on the cabinet door, and the door panel is movable along the width direction of the cabinet door, and the critical safety distance is the minimum sliding distance required for the door panel to not interfere with the outside world during the process of rotating the cabinet door from a closed position to a maximum opening angle;

[0099] Step 20: During the process of opening the door, determine whether the movement distance Δs of the door panel toward the door opening side reaches a critical safety distance, and control the door body to stop moving relative to the door.

[0100] It should be noted that the above steps 10 and 20 are only for the convenience of description and do not constitute a limitation on the chronological order.

[0101] In step 20, the door opening angle of the door body assembly may be determined, and the current moving distance Δs may be indirectly determined by the corresponding relationship between the door opening angle and the moving distance Δs. For example, when the door body assembly is opened, the motor controls the movement of the door panel at a uniform speed based on the door opening angle. At this time, the mapping relationship between the door opening angle and the moving distance Δs of the door panel can be obtained. Of course, the relationship between the door opening angle of the door body assembly and the moving distance Δs of the door panel can be a simple linear relationship or a nonlinear relationship. As long as it is ensured that the door panels do not interfere with each other during the door opening process, no further restrictions are made here. Of course, a sensor can also be provided to directly detect the current moving distance Δs of the door panel.

[0102] In addition, it should be noted that all the contents of the door assembly of the embedded refrigeration equipment can be used to explain the control method of the door assembly of the embedded refrigeration equipment, so the repeated contents will not be repeated.

[0103] Finally, it should be noted that the above embodiments are intended only to illustrate the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions of the technical solutions of the present application do not depart from the spirit and scope of the technical solutions of the present application and are intended to be encompassed by the claims of the present application.
