Technical Field

[0001] This invention relates to the field of refrigeration technology, and more particularly to door components of embedded refrigeration devices and embedded refrigeration devices. Background Technology

[0002] In today's society, rapid technological advancements have greatly driven changes in home lifestyles. Among these changes, built-in furniture, as a design concept that combines aesthetics and practicality, is favored by a wide range of consumers. Built-in furniture cleverly integrates appliances or storage space into the home environment, effectively saving space and significantly improving the overall harmony and aesthetics of the home. Take built-in refrigerators as an example: this design allows the refrigerator to be seamlessly embedded in cabinets, perfectly blending with the kitchen's decor and creating a modern yet harmonious living environment. However, despite the significant advantages of built-in refrigerators in enhancing home aesthetics and space utilization, a problem that cannot be ignored in actual use remains: the refrigerator door is prone to interference or collision with the cabinet sidewalls during opening, resulting in a less than ideal user experience. Summary of the Invention

[0003] This invention aims to at least solve one of the technical problems existing in related technologies. To this end, this invention proposes a door assembly for a refrigeration device that can solve the problems of interference and collision in door assemblies, thereby improving the user experience.

[0051] In today's society, the rapid progress of technology has greatly driven the transformation of home living styles. Among them, the embedded furniture, as a design concept that combines aesthetics and functionality, is favored by the majority of consumers. Embedded furniture cleverly integrates appliances or storage spaces into the home environment, not only effectively saving space, but also significantly improving the overall coordination and aesthetics of the home. Taking embedded refrigerators as an example, this design allows the refrigerator to seamlessly embed into the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, despite the significant advantages of embedded refrigerators in improving home aesthetics and space utilization, there is still a problem that cannot be ignored in the actual use process: the door body is prone to interference or collision with the cabinet side wall during opening, resulting in poor user experience of the embedded refrigerator.

[0052] Specifically, when the embedded refrigerator (hereinafter referred to as the refrigerator) meets the user's demand for both flat full embedding and full embedding, the refrigerator door body (hereinafter referred to as the door body) after being connected with the cabinet door panel (hereinafter referred to as the door panel) will cause the entire door body assembly to thicken, resulting in that after the refrigerator is pushed into the accommodating space of the cabinet, only relying on the original single-axis or double-axis structure hinge of the refrigerator, the door body assembly with the cabinet door will interfere with the cabinet during opening and closing, resulting in that it cannot be normally opened and used.

[0053] Therefore, the application provides a door body assembly (referred to as a door body assembly for short) which can enable the door body and the door panel to slide relative to each other, so that the door panel can slide towards the opening side of the door body during the process of opening the door body assembly, so that the hinge side still maintains the thickness of the door body during the process of opening the door, which is consistent with the opening door scene without the door panel; during the process of closing the door, the door panel moves towards the hinge side to return to the state before opening; so as to realize the refrigerator embedded installation demand in the case of with and without the door panel.

[0054] If the door panel and the door body continuously slide relative to each other, when the opening angle of the door is large, the sliding distance of the door panel of the door body is large, which can cause the user to panic and worry that the door panel will fall off, which affects the user experience, and this worry is particularly obvious when the refrigerator is full of load or the refrigerator is high. Based on this, the application further provides a door body assembly of an embedded refrigeration equipment, which can solve the interference problem of the door panel, and the door panel stops moving relative to the door body when the door is opened to a certain angle, thereby improving the user experience.

[0055] Please refer to Figure 1 and Figure 2 , the door body assembly includes a door body 2, a sliding mechanism 4 and a door panel 9. The door body 2 is rotatably connected to the refrigeration box body 1 of the refrigeration equipment, and the refrigeration box body 1 is used to be embedded into the accommodating space formed by the installation body. The installation body generally refers to the cabinet 6 in this case, of course, the installation body can also be a wall corner, or the installation body can also refer to other components, as long as it can form an accommodating space. Hereinafter, the installation body is taken as the cabinet 6 as an example for description. The door panel 9 is connected to the door body 2 by the sliding mechanism 4 to move relative to the width direction of the door body 2. The door body 2 has a critical opening angle, which is smaller than the maximum opening angle of the door body 2. During the process that the door body 2 is rotated from the closed position to the critical opening angle, the sliding mechanism drives the door panel 9 to move relative to the door body 2. During the process that the door body 2 is rotated from the critical opening angle to the maximum opening angle, the door panel 9 is stationary relative to the door body 2. During the process that the door body 2 is rotated from the closed position to the critical opening angle, the moving distance Δs of the door panel 9 needs to ensure that the door panel 9 does not interfere during the entire opening process, and thus the moving 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 during the process that the door body 2 is rotated from the closed position to the maximum opening angle.

[0056] According to the embodiments of the present application, during the opening process of the door body assembly, the door panel 9 stops relative sliding before the maximum opening angle is reached, that is, during the latter part of the opening process, the door panel 9 is stationary relative to the cabinet door 2, thereby improving the stability of the door body assembly structure, making the movement of the door panel 9 more concealed, and reducing the user's concern about the door panel 9 falling off. Moreover, since the greater the opening angle of the door body assembly, the closer it is to the user, the door panel 9 stops sliding in advance, which can reduce the noise during the opening process and improve the user experience.

[0057] According to the embodiments of the present application, the range of the critical safety distance can be determined in various different ways.

[0058] In one embodiment, if the maximum opening angle of the door body assembly is ninety degrees, in order to satisfy the condition that the door body assembly does not interfere, one necessary condition is that there is an assembly gap d2 between the door panel 9 and the panel of the cabinet 6 when the cabinet door 2 is opened by ninety degrees, where the panel of the cabinet 6 is the second cabinet panel 602 in the figure, and the first cabinet panel 601 also belongs to the panel of the cabinet 6. In order to ensure that there is an assembly gap d2 between the door panel 9 and the panel of the cabinet 6 when the cabinet door 2 is opened by ninety degrees, the movement distance of the door panel 9 relative to the cabinet door 2 is L2-L1=c+d2+{x-(a-b)+d3+h}. Further, as long as the movement distance Δs is not less than L2-L1, it can be ensured that the door panel 9 does not interfere with the outer surface of the second cabinet panel 602 when the cabinet door 2 is opened by ninety degrees. The assembly gap d2 is generally greater than zero, and in the extreme case, the assembly gap d2 can also be equal to zero, and thus the door panel 9 does not contact the second cabinet panel 602 when the cabinet door 2 is opened by ninety degrees.

[0059] where L2=y+c+d2, L1=y-{x-(a-b)+d3+h}, L2-L1=c+d2+{x-(a-b)+d3+h}.

[0060] where y is the width of the cabinet door 2, c is the width difference between the door panel 9 and the cabinet door 2 (not labeled in the figure, and some parameters are not labeled in the figure later), d2 is the assembly gap reserved between the cabinet door and the panel of the mounting body when the cabinet door 2 is opened to the maximum opening angle, x is the thickness of the cabinet door 2, a is the longitudinal axis distance of the cabinet door 2, that is, the distance from the inner surface of the cabinet door 2 to the hinge shaft center 101 of the cabinet door 2 when the cabinet door 2 is closed, b is the transverse axis distance of the cabinet door 2, that is, the distance from the end surface of the hinge side of the cabinet door 2 to the hinge shaft center 101 of the cabinet door 2 when the cabinet door 2 is closed, d3 is the assembly gap between the cabinet door 2 and the cabinet door, and h is the thickness of the cabinet door.

[0061] According to the embodiment of the present application, when the assembly gap d3 between the cabinet 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 assembly is x+d3+h=x+29.

[0062] When the door panel 9 is opened to 90°, the cabinet door 2 exceeds the edge line L1 of the cabinet 6 by y-{x-(a-b)+d3+h}, and when the transverse axis distance b of the cabinet door 2 is 12.5 mm, L1=y-{x-(a-12.5)+6+23}=y-x+a+41.5.

[0063] When the door panel 9 is opened to 90°, the door panel 9 exceeds the edge line L2 of the cabinet 6 by y+c+d2, when the width difference c of the door panel 9 and the cabinet door 2 is equal to 8 mm, and the assembly gap d2 reserved between the door panel and the cabinet door 2 when the cabinet door is opened to the maximum opening angle is 5 mm, y+c+d2=y+13.

[0064] In summary, when the door panel 9 is opened to 90°, the distance between the door panel 9 and the cabinet door 2 is L2-L1=y+13-(y-x+a+41.5)=x+a+54.5, and the units in the above formula are millimeters.

[0065] That is, when the cabinet door moves a distance Δs of x+a+54.5 relative to the cabinet door 2, the non-interference with the second cabinet panel 602 during the entire 90° opening process can be achieved. During the opening process, the earlier the distance is achieved, the better the user experience, that is, only when the door is just opened, the cabinet door 2 and the door panel 9 will slide, and subsequently when the door angle increases, the load and bearing of the cabinet door 2 gradually increase, and at this time, the cabinet door 2 and the door panel 9 no longer slide relative to each other, which increases the stability of the refrigerator.

[0066] Based on the above requirements, the embodiment of the present application uses motion simulation or formula calculation to obtain the parameters of the sliding mechanism. If the sliding mechanism is realized through a connecting rod, the length and initial angle of the connecting rod can be calculated, and if the sliding mechanism is realized through a gear transmission, the gear teeth and pressure angle can be calculated. In this way, the cabinet door 2 and the door panel 9 have relative sliding when the refrigerator is just opened, and stop relative sliding at a certain angle, that is, when the cabinet door 2 is fully opened, the cabinet door 2 and the door panel 9 are in a relative static state, thereby improving the user experience.

[0067] The sliding mechanism takes a connecting rod mechanism as an example, the length of the connecting rod is m, and the initial angle is a. According to the adams motion simulation or theoretical calculation, when the length of the connecting rod and the initial angle are a certain specific value, the displacement values corresponding to different door opening angles can be obtained. This is only to find the door opening angle corresponding to the relative sliding distance value mentioned above, and the corresponding length of the connecting rod and the initial angle value can be found. When the angle exceeds this angle, the door panel 9 and the cabinet door 2 no longer appear relative sliding. Similarly, when closing the door, the opposite is true, that is, when the cabinet door 2 and the door panel 9 do not slide relative to each other at the beginning, sliding occurs at a certain angle until the door is completely closed. As an example, when the length of the connecting rod is 77 mm and the initial angle is 14.5°, the displacement relationship is as shown in Table 1 below, according to the final required distance of the door panel 9 exceeding the cabinet door 2 of the refrigerator door 2, the corresponding parameters in the table are queried, that is, when the critical safety distance of the door panel 9 exceeding the cabinet door 2 is 61 mm, the door is opened by 50°, and the subsequent 40° opening of the door does not require relative sliding. According to the actual thickness and other parameters of the door body, the length of the connecting rod can be adjusted to reduce the opening angle at which the sliding stops.

[0068]

[0069] In another embodiment, in order to determine the critical safety distance, the first interference site and the second interference site on the door panel 9 which are most likely to interfere can be determined first, and the first interference site and the second interference site are always determined based on the first interference site and the second interference site not interfering with the accommodation space to obtain the value interval of the critical safety distance.

[0070] Please refer to Figures 4 to 6 According to the embodiments of the present application, the door panel 9 has a first interference site c and a second interference site d, the first interference site is located at the inner corner of the door opening side of the door panel 9, and the second interference site is located at the outer corner of the hinge side of the door panel 9. The "inner" and "outer" are relative to the refrigeration cabinet 1, the side facing the refrigeration cabinet 1 is the "inner" side, and the side away from the refrigeration cabinet 1 is the "outer" side. Since Figure 4 is a top view, the first interference site and the second interference site are points from Figure 4 It can be understood that for the door body assembly, the first interference site and the second interference site are a vertical line respectively. If the inner corner of the door opening side is in the form of a circular arc, the first interference site at this time is the point on the arc segment farthest from the hinge shaft 101 of the cabinet door 2. Similarly, if the outer corner of the hinge side of the door panel 9 is in the form of a circular arc, the second interference site at this time is the point on the arc segment farthest from the hinge shaft 101 of the cabinet door 2. The critical safety distance satisfies: before the first interference site leaves the accommodation space, there is a gap between the first interference site and the side wall of the accommodation space corresponding thereto; when the second interference site leaves the accommodation space, there is a gap between the second interference site and the side wall of the accommodation space corresponding thereto.

[0071] In combination Figures 4 to 6 When the box door 2 is closed, the distance between the end face of the door panel 9 on the opening side and the side wall of the accommodating space corresponding thereto is δ1, and the distance between the end face of the door panel 9 on the hinge side and the side wall of the accommodating space corresponding thereto is δ2.

[0072] δ1 is not less than the movement distance γ of the first interference site along the width direction of the accommodating space before the first interference site leaves the accommodating space, and γ is the vertical distance of the first interference site moving toward the side wall of the accommodating space corresponding thereto. δ2 is not less than the movement distance λ of the second interference site along the width direction of the accommodating space before the second interference site leaves the accommodating space, and λ is the vertical distance of the second interference site moving toward the side wall of the accommodating space corresponding thereto, that is, δ1≥γ and δ2≥λ. "Before the first interference site leaves the accommodating space" corresponds to the case before the point c of the first interference site and the point e of the cabinet 6 are flush, that is, the point c of the interference site is located before the horizontal line where the point e is located. "Before the second interference site leaves the accommodating space" corresponds to the case before the point d of the second interference site and the point f of the cabinet 6 are flush, that is, the point d of the interference site is located before the horizontal line where the point f is located.

[0073] Generally, δ1>γ and δ2>λ are required, and of course, δ1=γ and δ2=λ in an extreme case are not excluded. Among them, when the box door 2 is in the closed position, the width direction of the box door 2 is consistent with the width direction of the accommodating space. With the opening of the box door 2, the width direction of the box door 2 and the width direction of the accommodating space form an angle at this time.

[0074] According to the embodiment of the present application, it is assumed that the distance Δs of the door panel 9 is moved, and the length of the side where the point c and the hinge shaft center 101 (that is, the point o) are located is a, and the angle between a and the horizontal line in the figure is α. At this time, the length of the side where the point d and the hinge shaft center 101 (that is, the point o) are located is b, and the angle between b and the horizontal line in the figure is β.

[0075] Figures 2 to 4In the figure, the relationship and angle relationship between the position of the refrigeration device (refrigerator) when the door is initially not opened and when the door 2 is opened to any angle (indicated by the dashed line in the figure) are assumed to be simplified and described. In the figure, the corners that can interfere during the opening of the door are marked with black dots. The first interference point c is prone to interference with the e point, which is the outer corner of the right end of the first cabinet panel 601. That is, the e point is the critical point at which the c point escapes from interference (leaves the accommodation space) during the opening and closing of the door. The second interference point d is the corner point of the outer corner of the right end of the door panel 9, which is the corner point at which 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 opening and closing of the door. As can be seen from the figure, at the initial position, the angle between the oblique side oc between the c point and the hinge shaft center 101 (o point) and the inner side of the door panel is θ0, and the angle of the door 2 when opened to any position is Δθ. The oblique side oc at this position, the distance l2 and the distance l1 are indicated by dashed lines. At the initial position, the oblique side od between the d point and the hinge shaft center 101 on the right side of the hinge shaft center 101, and the oblique side od at the position when the door 2 is opened to any angle Δθ, the distance l1+h and the distance l3 are indicated by dashed lines. As can be seen from the figure, during the opening of the door 2, if the door panel does not move towards the opening side of the door 2, as the opening angle increases, the d point 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 and affect the opening of the door, the door panel 9 needs to move a distance Δs towards the opening side of the door 2 when the door is opened to an angle of Δθ during the opening process.

[0076] In one embodiment, δ1≥γ=a×cosα-l2.

[0077] wherein,

[0078] As described 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 opening side of the door 2 during the opening process of the door 2.

[0079] In one embodiment, δ2≥λ=b*cosβ-l3.

[0080] wherein,

[0081] Thus, when l1, l2, l3, h, δ1 and δ2 are determined, the range of values of Δs can be obtained.

[0082] The above formula for calculating Δs does not constitute a limitation on Δs, for example, the above calculation formula can also have a correction factor or a correction parameter. In addition, the above calculation formula is determined for the hinge shaft 101, if the box door 2 is installed with a double shaft hinge or a movable hinge, the hinge shaft 101 will change with the opening of the box door 2, and then the calculation formula of Δs is also adaptively changed, and the formula needs to calculate the movement distance of the hinge shaft 101. In addition, if there is a mounting gap between the door plate 9 and the box door 2, then h in the above calculation formula is the distance between the sliding surface of the door plate 9 and the outer surface of the door plate 9, and l1 is the distance from the hinge point of the box door 2 to the sliding surface of the door plate 9.

[0083] Wherein, δ1 and δ2 are generally not more than 5mm, for example, when δ1 = δ2 = 4mm, then the range of Δs can be obtained.

[0084] According to the embodiment of the application, the critical opening angle is between 1° and 105°. That is, when the box door 2 is opened to the critical opening angle, the door plate 9 no longer slides relative to the box door 2, thereby ensuring the stability of the door body assembly structure and improving the user experience.

Alternatively, referring to Figure 8 The first track can be in the form of a rack 406 in the sliding mechanism 4, and the first moving part can be a gear 407 engaged with the rack 406. The specific structure of the first track and the first moving part is not limited here, as long as the first moving part can move along the first track.

[0087] According to one embodiment of the application, please refer to Figure 9The sliding mechanism 4 comprises a base (not labeled), 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 is slidably installed on the second track 401, the third moving part 404 is slidably installed on the third track 402, the third moving part 404 is connected with the door panel 9; a connecting piece is connected with the second moving part 403 and the third moving part 404 at two ends respectively, the traction mechanism drives the second moving part 403 to move along the second track 401, the second moving part 403 drives the third moving part 404 to move along the third track 402 through the connecting piece, and the moving directions of the second moving part 403 and the third moving part 404 are opposite.

[0088] According to the embodiment of the present application, the connecting piece can be a flexible cable, for example, 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. In addition, the second track 401 and the third track 402 can both adopt the structure form of a sliding rail, and at this time, the second moving part 403 and the third moving part 404 can both adopt the structure form of a sliding block. Of course, the specific structure forms of the second track 401, the third track 402, the second moving part 403 and the third moving part 404 are not limited by the examples herein, as long as the second moving part 403 slides along the second track 401 and the third moving part 404 moves along the third track 402.

[0089] According to the embodiment of the present application, the connecting piece can comprise a first flexible cable and a second flexible cable.

[0090] The specific structure form of the sliding mechanism 4 is not limited by the examples herein, as long as the traction mechanism can promote the door panel 9 to move relative to the cabinet door 2 when the sliding mechanism 4 is driven to move. For example, the sliding mechanism 4 can be the above-mentioned structure of double sliding rails and sliding blocks, can also adopt the structure form of a gear 407 and a rack 406 cooperating, etc., for reference Figure 6 The sliding mechanism 4 comprises a gear 407 and a rack 406, the gear 407 is connected with the output shaft of the traction mechanism, and the rack 406 is fixedly connected with the door panel 9.

[0091] According to the embodiment of the present application, during the opening process of the door body assembly, the door panel is stationary relative to the cabinet door in advance before being rotated to the maximum opening angle.

[0092] In one case, the movement of the door plate is controlled by the motor. For example, the motor drives the sliding mechanism to move the door body relative to the cabinet door. At this time, the controller controls the start and stop of the motor to achieve the purpose.

[0093] In another case, the movement of the door plate relative to the cabinet door is driven by a mechanical structure. That is, by selecting a suitable sliding mechanism, the sliding mechanism has an engaged state and a disengaged state. In the engaged state, the door plate can move relative to the cabinet door under the drive of the sliding mechanism. In the disengaged state, the door plate is stationary relative to the cabinet door. Specifically, before the moving distance Δs of the door plate reaches the critical safety distance, the sliding mechanism is in the engaged state. After the moving distance Δs of the door plate reaches the critical safety distance, the sliding mechanism is in the disengaged state.

The motor is power coupled to the arc gear 504 to drive the arc gear 504 to rotate. Of course, in order to realize the switching between the engaged state and the disengaged state, the specific type of the sliding mechanism 4 is not limited by the above example.

[0095] According to the embodiments of the present application, an embedded refrigeration device is provided, which comprises a refrigeration cabinet 1 and a door assembly. The refrigeration cabinet 1 is adapted to be embedded into a containing space. The door assembly is installed on the refrigeration cabinet 1.

[0096] According to the embodiments of the present application, a control method of a door assembly of an embedded refrigeration device is provided, which comprises:

[0097] Step 10: determining a critical safety distance of the door assembly when rotating relative to the refrigeration cabinet based on the size parameters of the door assembly. The refrigeration cabinet of the refrigeration device is adapted to be embedded into a containing space formed by the installation body. The cabinet door of the door assembly is adapted to be rotatably connected to the refrigeration cabinet. The door plate of the door assembly is movably installed on the cabinet door and can move along the width direction of the cabinet door. The critical safety distance is the minimum sliding distance required for the door plate to not interfere with the outside during the process of the cabinet door rotating from the closed position to the maximum opening angle.

[0098] Step 20: determining that the moving distance Δs of the door plate towards the door opening side of the cabinet door reaches the critical safety distance during the opening of the cabinet door, and controlling the door body to stop moving relative to the cabinet door.

[0099] It should be noted that the above steps 10 and 20 are only for convenient description, and do not constitute a limitation on the sequence of the timing.

[0100] In step 20, the opening angle of the door body assembly can be determined, and the current moving distance As can be indirectly determined according to the corresponding relationship between the opening angle and the moving distance As. For example, when the motor controls the door panel to move at a constant speed based on the opening angle during the opening of the door body assembly, the mapping relationship between the opening angle and the moving distance As of the door panel can be obtained. Of course, the relationship between the opening angle of the door body assembly and the moving distance As of the door panel can be a simple linear relationship or a nonlinear relationship, as long as the door panel does not interfere during the opening process. Here, no more limitation is made. Of course, a sensor can also be arranged to directly detect the current moving distance As of the door panel.

[0101] In addition, it should be noted that all the above contents of the door body assembly of the embedded refrigeration device can be used to explain the control method of the door body assembly of the embedded refrigeration device, and therefore the repeated contents will not be described again.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the present application, and are not a limitation on the present application. Although the present application is described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
