Description

Technical Field

[0001] The present disclosure relates to a cabinet assembly and a refrigerator. Background Art

[0002] The door is a crucial component of the refrigerator system, primarily used to open and close the access panel and potentially equipped with touchscreen and display features. Normally, the door is attached to the refrigerator by hinges, allowing for circular rotation around the hinge axis. In some cases, the refrigerator is placed in a corner, requiring a certain distance from the wall to ensure the door can open at an angle greater than 90°. To conserve space, built-in refrigerators are a major future development trend. However, traditional hinge mechanisms for built-in refrigerators often hinder effective door opening.

[0048] Figure 1 Schematic diagram of the structure of some embodiments of the box assembly according to the present disclosure. Figure 1 In some embodiments, the box assembly includes a box body 1 and a door body 2.

[0049] The box body 1 is provided with a take-in / take-out opening 11. Articles can be stored in the box body 1 or taken out from the box body 1 through the take-in / take-out opening 11.

[0050] The door body 2 is provided on the box body 1 and is configured to open or close the access opening 11. When the door body 2 is in a closed state, the access opening 11 is closed.

[0051] refer to Figures 2 to 4 The door body 2 includes a first side wall 21, a second side wall 22, and a third side wall 23. The first side wall 21 is farther away from the housing 1 than the second side wall 22. The third side wall 23 is located on the extension surface N of the side wall 12 of the housing 1. The third side wall 23 intersects with the first side wall 21 to form a first ridge line L1. The third side wall 23 intersects with the second side wall 22 to form a second ridge line L2. The first motion trajectory A of the first ridge line L1 during the opening or closing process of the door body 2 is located on the inner side of the extension surface N.

[0052] The sidewall 12 of the box body 1 is coplanar with the extension surface N. The inner side of the extension surface N refers to the side closer to the interior of the box body 1. The first sidewall 21 is farther from the box body 1 than the second sidewall 22, meaning that the first sidewall 21 is farther from the front of the box body 1 than the second sidewall 22. The front of the box body 1 is where the access opening 11 is located.

[0053] The third side wall 23 intersects with the first side wall 21 to form a first angle. The first ridgeline L1 is the tip of the first angle. Of course, the first angle can be rounded, in which case the first ridgeline L1 is a virtual line. The third side wall 23 intersects with the second side wall 22 to form a second angle. The second ridgeline L2 is the tip of the second angle. Of course, the second angle can be rounded, in which case the second ridgeline L2 is a virtual line.

[0054] The embodiment of the present disclosure sets a first motion trajectory A so that the door body 2 opens and closes under boundary restriction conditions. The first edge line L1 of the door body 2 moves along the first motion trajectory A during the opening or closing process of the door body 2. The first motion trajectory A is always located on the inner side of the extension surface N. Therefore, during the opening or closing process of the door body 2, the first edge line L1 will not exceed the side wall 12 of the box body 1, thereby reducing the reserved space required for opening and closing the door on the side of the box body 1, so that the door body 2 can be opened better.

[0055] refer to Figure 1 In the coordinate system, the first direction X is parallel to the depth direction of the box 1, and the depth direction is parallel to the direction from the front to the back of the box 1. The second direction Y is parallel to the width direction of the box 1, and the side wall 12 of the box 1 is located in the second direction Y. The third direction X is parallel to the height direction of the box 1. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0056] refer to Figure 2 When the door body 2 is closed, the first side wall 21 of the door body 2 is located outside the second side wall 22. The first side wall 21 is the front wall of the door body 2, and the second side wall 22 is the rear wall of the door body 2. In other words, the second side wall 22 is the wall surface close to the access opening 11. When the door body 2 is closed, the direction from the first side wall 21 to the second side wall 22 is parallel to the first direction X.

[0057] The door body 2 further includes a top wall 24 , which is located in the third direction Z. The top wall 24 is located at the top of the first side wall 21 , the second side wall 22 and the third side wall 23 , and the top wall 24 connects the first side wall 21 , the second side wall 22 and the third side wall 23 .

[0058] refer to Figure 4 In some embodiments, the distance between the first motion trajectory A and the extension surface N increases as the opening angle of the door body 2 increases.

[0059] When the door body 2 is in the closed state, the distance between the first edge line L1 and the extension surface N is the shortest. As the opening angle of the door body 2 gradually increases, the first edge line L1 moves along the first motion trajectory A, and the distance between the first edge line L1 and the extension surface N also increases accordingly.

[0060] In some embodiments, the distance between the first motion trajectory A and the box body 1 decreases as the opening angle of the door body 2 increases.

[0061] The distance between the first motion trajectory A and the box 1 refers to the distance between the first motion trajectory A and the front of the box 1. The front of the box 1 is located in the first direction X, and is the side facing the box 1 when the user opens the door 2.

[0062] When the door body 2 is in the closed state, the distance between the first edge line L1 and the box body 1 is the farthest. As the opening angle of the door body 2 gradually increases, the first edge line L1 moves along the first motion trajectory A, and the distance between the first edge line L1 and the box body 1 decreases accordingly.

[0063] In some embodiments, the first motion trajectory A is tangent to the extension surface N, and the tangent point is the first point a1 of the first motion trajectory A. The first point a1 is located on the first ridge line L1 when the door body 2 is in the closed state.

[0064] refer to Figure 4 The first motion trajectory A includes a first point a1, a second point a2, and a third point a3. The first point a1 is the tangent point between the first motion trajectory A and the extension surface N. When the door body 2 is in the closed state, the first ridge line L1 passes through the first point a1. It can also be said that the first point a1 is the starting point of the first motion trajectory A when the door body 2 is in the process of being fully opened from the closed state. The second point a2 is located between the first point a1 and the third point a3. When the door body 2 is in the fully opened state, the first ridge line L1 passes through the third point a3. Therefore, it can also be said that the third point a3 is the ending point of the first motion trajectory A when the door body 2 is in the process of being fully opened from the closed state.

[0065] refer to Figures 4 to 7 When the door body 2 is fully opened from the closed state, the first edge line L1 moves along the first motion trajectory A in the direction of the first point a1, the second point a2 and the third point a3. Figure 7 、 Figure 6 、 Figure 5 and Figure 4 In the process of the door body 2 moving from a fully opened state to a closed state, the first edge line L1 moves along the first motion trajectory A in the directions of the third point a3, the second point a2 and the first point a1.

[0066] In some embodiments, the second motion trajectory B of the second ridge line L2 is located inside the extension surface N during the opening or closing process of the door body 2 .

[0067] The first edge line L1 is away from the box body 1 relative to the second edge line L2. When the door body 2 is in the closed state, the second edge line L2 is located on the inner side of the first edge line L1. During the opening or closing process of the door body 2, the first movement trajectory A of the first edge line L1 is located on the inner side of the extension surface N. Correspondingly, the second movement trajectory B of the second edge line L2 is located on the inner side of the extension surface N. Therefore, the corner parts (the first edge line L1 and the second edge line L2) during the opening or closing process of the door body 2 will not exceed the side wall 12 of the box body 1, reducing the reserved space required for opening and closing the door on the side of the box body 1.

[0068] In some embodiments, the distance between the second motion trajectory B and the extension surface N increases as the opening angle of the door body 2 increases.

[0069] When the door body 2 is in the closed state, the distance between the second ridge line L2 and the extension surface N is the shortest. As the opening angle of the door body 2 gradually increases, the second ridge line L2 moves along the second motion trajectory B, and the distance between the second ridge line L2 and the extension surface N also increases accordingly.

[0070] In some embodiments, the distance between the second motion trajectory B and the box body 1 first decreases and then increases as the opening angle of the door body 2 increases.

[0071] When the door body 2 is in the closed state, the second ridge line L2 is far away from the box body 1. As the opening angle of the door body 2 gradually increases, the second ridge line L2 moves along the second motion trajectory B, and the distance between the second ridge line L2 and the box body 1 first decreases and then increases.

[0072] When the door 2 is fully opened, the distance between the second ridge line L2 and the box body 1 is a first distance. When the door 2 is closed, the distance between the second ridge line L2 and the box body 1 is a second distance. The first distance is greater than the second distance.

[0073] In some embodiments, the point at which the second motion trajectory B is at the shortest distance from the box 1 is the closest point b2 , and a tangent line L3 of the second motion trajectory B passing through the closest point b2 is perpendicular to the extension surface N.

[0074] In some embodiments, assuming that when the door 2 is closed, the distance between the box body 1 and the second side wall 22 is S, the distance between the closest point b2 and the box body 1 is greater than or equal to 40% S and less than or equal to 60% S. Optionally, the distance between the closest point b2 and the box body 1 is 50% S.

[0075] In some embodiments, the distance between the closest point b2 and the box body 1 is greater than zero and less than or equal to 10 mm. Optionally, the distance between the closest point b2 and the box body 1 is 5 mm.

[0076] In some embodiments, the extended surface N is used as the first boundary surface during the opening or closing process of the door body 2, and the surface where the tangent line L3 is located is used as the second boundary surface during the opening or closing process of the door body 2. The second boundary surface is parallel to the front surface of the box body 1. The first edge line L1 of the door body 2 moves along the first motion trajectory A and never exceeds the first boundary surface. The second edge line L2 of the door body 2 moves along the second motion trajectory B and never exceeds the second boundary surface. By presetting the two boundary surfaces, two appropriate points are selected on the door body 2 (the first edge line L1 and the second edge line L2 are points in the top view of the door body 2), and the trajectory lines of the two appropriate points during the opening or closing process of the door body 2 are set. The two points move along the corresponding trajectory lines to achieve an embedded solution that meets the boundary conditions.

[0077] The plane where the tangent line L3 lies is parallel to the front surface of the box body 1. When the door body 2 is closed, the plane where the tangent line L3 lies is parallel to the first side wall 21 and the second side wall 22. The plane where the tangent line L3 lies is perpendicular to the third side wall 23.

[0078] In some embodiments, the opening angle of the door body 2 corresponding to the point where the distance between the second motion trajectory B and the box body 1 is the smallest is 25° to 30°.

[0079] The point where the second motion trajectory B has the smallest distance from the box body 1 is the closest point b2. When the second edge line L2 passes through the closest point b2, the corresponding opening angle of the door body 2 is 25° to 30°.

[0080] Optionally, the opening angle of the door body 2 corresponding to the point where the distance between the second motion trajectory B and the box body 1 is the smallest is 25°, 30°, or 28°, etc.

[0081] refer to Figure 4 , the second motion trajectory B includes the fourth point b1, the nearest point b2 and the fifth point b3. When the door body 2 is in the closed state, the second ridge line L2 passes through the fourth point b1. It can also be said that the fourth point b1 is the starting point of the second motion trajectory B in the process of the door body 2 going from the closed state to the fully opened state. The nearest point b2 is located between the fourth point b1 and the fifth point b3. The nearest point b2 is the point where the distance between the second motion trajectory B and the box body 1 is the smallest. The tangent line L3 of the second motion trajectory B passing through the nearest point b2 is perpendicular to the extension surface N. When the door body 2 is in the fully opened state, the second ridge line L2 passes through the fifth point b3. Therefore, it can also be said that the fifth point b3 is the ending point of the second motion trajectory B in the process of the door body 2 going from the closed state to the fully opened state.

[0082] refer to Figures 4 to 7 When the door body 2 is fully opened from the closed state, the second edge line L2 moves along the second motion trajectory B in the direction of the fourth point b1, the nearest point b2 and the fifth point b3. Figure 7 、 Figure 6 、 Figure 5 and Figure 4 In the process of the door body 2 moving from the fully opened state to the closed state, the second edge line L2 moves along the second motion trajectory B in the direction of the fifth point b3, the nearest point b2 and the fourth point b1.

[0083] refer to Figure 4 When the door body 2 is in the closed state, the first edge line L1 passes through the first point a1 of the first motion trajectory A, and the first point a1 is the tangent point between the first motion trajectory A and the extension surface N; the second edge line L2 passes through the fourth point b1 of the second motion trajectory B.

[0084] refer to Figure 5When the door body 2 is opened at the first angle, the point where the first edge line L1 passes through the first motion trajectory A is between the first point a1 and the third point a3, and the second edge line L2 passes through the nearest point b2 of the second motion trajectory B, and the nearest point b2 is between the fourth point b1 and the fifth point b3. The nearest point b2 is the minimum point of the distance between the second motion trajectory B and the box body 1.

[0085] refer to Figure 6 When the door body 2 is opened at the second angle, the point where the first edge line L1 passes through the first motion trajectory A is located between the first point a1 and the third point a3, and the point where the second edge line L2 passes through the second motion trajectory B is located between the fourth point b1 and the fifth point b3.

[0086] refer to Figure 7 When the door body 2 is opened at the third angle, the point where the first ridge line L1 passes through the first motion trajectory A is located at the third point a3, and the point where the second ridge line L2 passes through the second motion trajectory B is located at the fifth point b3.

[0087] The first angle is smaller than the second angle, and the second angle is smaller than the third angle.

[0088] The first angle ranges from 25° to 30°. Optionally, the first angle is 30°.

[0089] The second angle ranges from 30° to 120°. Optionally, the second angle is 90°.

[0090] The third angle has an angle range of greater than or equal to 120°. Optionally, the third angle is 120°.

[0091] refer to Figure 3 In some embodiments, the box assembly further includes a connector 3 , and the box 1 and the door 2 are connected via the connector 3 .

[0092] In some embodiments, the connecting member 3 includes a first connecting member 31 and a second connecting member 32 .

[0093] The first connecting member 31 is disposed on the door body 2 or the box body 1 , and the first connecting member 31 includes a shaft 33 .

[0094] The second connecting member 32 is provided on the housing 1 or the door 2 and includes a groove 34. The groove 34 accommodates the shaft 33 and guides the movement of the shaft 33 during the opening or closing process of the door 2, so that the first movement trajectory A of the first edge line L1 during the opening or closing process of the door 2 is located inside the extension surface N.

[0095] refer to Figure 3 The first connecting member 31 is provided on the door body 2 , and the second connecting member 32 is provided on the box body 1 .

[0096] Optionally, a mounting groove 241 is provided at a position of the top wall 24 of the door body 2 close to the third side wall 23 , and the first connecting member 31 is provided in the mounting groove 241 .

[0097] Of course, the first connecting member 31 may also be provided on the box body 1 , and the second connecting member 32 may be provided on the door body 2 .

[0098] The shaft 33 on the first connecting member 31 is inserted into the groove 34 on the second connecting member 32 . When the door body 2 is opened or closed, the shaft 33 moves in the groove 34 , and the groove 34 guides the movement of the shaft 33 .

[0099] The shape of the groove 34 is used to define the movement trajectory of the shaft 33 .

[0100] In some embodiments, the shaft 33 includes a first shaft 331 and a second shaft 332 , and the groove 34 includes a first groove 341 and a second groove 342 . The first groove 341 accommodates the first shaft 331 , and the second groove 342 accommodates the second shaft 332 .

[0101] The first shaft 331 is inserted into the first slot 341 , and the second shaft 332 is inserted into the second slot 342 . The first slot 341 guides the movement of the first shaft 331 , and the second slot 342 guides the movement of the second shaft 332 .

[0102] The second connecting member 32 is fixed on the box body 1, and has a first groove 341 and a second groove 342; the first connecting member 31 is fixed to the end of the door body 2, and has a first axis 331 and a second axis 332; when the door body 2 is opened from 0° to 120°, the trajectory of the center point of the first axis 331 forms the center trajectory curve of the first groove 341, and the trajectory of the center point of the second axis 332 forms the center trajectory curve of the second groove 342.

[0103] The positions of the first axis 331 and the second axis 332 on the first connecting member 31 can be changed, and different positions of the first axis 331 and the second axis 332 can form different center trajectory curves of the first groove 341 and the second groove 342 to realize an embedded opening and closing door.

[0104] The operating principle of door body 2 is as follows:

[0105] When the door body 2 needs to be opened, force is applied to the door body 2, the first axis 331 on the door body 2 moves along the first groove 341, and the second axis 332 on the door body 2 moves along the second groove 342. During the opening process of the door body 2, the two corners at the end (the corners where the first edge line L1 and the second edge line L2 are located) will move according to the motion trajectory that conforms to the boundary definition.

[0106] In some specific embodiments, the trajectory lines of the two axes are determined according to a preset boundary surface to realize the structural features and assembly relationship of the embedded switch door components.

[0107] The extended surface N of the side wall 12 of the box body 1 serves as the first boundary surface. When the box body 1 is embedded, the side wall serves as the reference surface M. When the door body 2 does not exceed the extended surface N of the side wall 12 of the box body 1 during opening, the extended surface N of the side wall 12 of the box body 1 can be infinitely close to the reference surface M, that is, the gap between the side wall 12 of the box body 1 and the side wall can be minimized, and even the side wall 12 of the box body 1 and the reference surface M can be aligned, with the distance being zero. The second boundary surface of the front face of the box body 1 is a plane passing through the tangent line L3, and the second boundary surface is perpendicular to the extended surface N. The distance of the second boundary surface from the front face of the box body 1, that is, the distance between the second boundary surface and the front face of the box body 1 in the first direction X, can be adjusted as needed.

[0108] For example, when the box 1 has two doors 2 arranged side by side, the distance that the second boundary surface deviates from the front of the box 1 is related to the distance between the two doors 2 and the distance between the door 2 and the front of the box 1.

[0109] When the door 2 is closed, the first ridge L1 is away from the front of the box 1, and the second ridge L2 is close to the front of the box 1. When the door 2 is opened or closed, the first ridge L1 always moves along the first motion trajectory A. The second ridge L2 always moves along the second motion trajectory B.

[0110] The first motion trajectory A is a circular arc curve whose radius and center position can change. Among them, the first point a1 is the starting point of the door body 2 opening process, and the first point a1 is the tangent point between the first motion trajectory A and the extension surface N. The third point a3 is the end point of the door body 2 opening process. When the first edge line L1 passes through the third point a3, the opening angle of the door body 2 is the largest. The second point a2 is located between the first point a1 and the third point a3. In the process of the first motion trajectory A changing from the first point a1 to the second point a2 to the third point a3, the first motion trajectory A extends toward the front of the box body 1 and away from the extension surface N.

[0111] Similarly, the second motion trajectory B is a circular arc curve whose radius and center position can change. Among them, the fourth point b1 is the starting point in the process of opening the door body 2, the fifth point b3 is the end point in the process of opening the door body 2, and the nearest point b2 is located between the fourth point b1 and the fifth point b3. The nearest point b2 is the minimum point of the distance between the second motion trajectory B and the box 1, and the tangent L3 of the second motion trajectory B through the nearest point b2 is perpendicular to the extension surface N. In the process of the second motion trajectory B changing from the fourth point b1 to the nearest point b2 to the fifth point b3, the second motion trajectory B first extends toward the front of the box 1 and then toward the front away from the box 1, and at the same time extends in the direction away from the extension surface N.

[0112] In some specific embodiments, the design method of the opening effect of the door body 2 is:

[0113] First, determine the effect of opening the door body 2 (determine the extension surface N and the reference surface M);

[0114] Then, according to the desired effect, some more constraints are added to determine the motion curves of the two corners of the door body 2 (the angle formed by the intersection of the first side wall 21 and the third side wall 23, and the angle formed by the intersection of the second side wall 22 and the third side wall 23) (determine the first motion trajectory A and the second motion trajectory B);

[0115] Then, assuming that the two corners of the door body 2 move along the above motion curve, the trajectory curves of the first axis 331 and the second axis 332 on the door body 2 are determined, and then the first groove 341 and the second groove 342 are determined according to the trajectory;

[0116] Finally, the second connecting member 32 is provided with a first groove 341 and a second groove 342, and the second connecting member 32 is fixedly mounted on the box body 1. The first connecting member 31 is provided with a first shaft 331 and a second shaft 332, and the first connecting member 31 is fixedly mounted on the door body 2. The door body 2 can achieve a preset opening effect.

[0117] The shapes of the first groove 341 and the second groove 342 do not necessarily have to be the same.

[0118] Optionally, the first groove 341 is an arcuate groove, or a combination of an arcuate groove and a straight groove. The second groove 342 is an arcuate groove, or a combination of an arcuate groove and a straight groove.

[0119] refer to Figure 8 The first shaft 331 is disposed within the first slot 341, which includes a first end and a second end. The second shaft 332 is disposed within the second slot 342, which includes a third end and a fourth end. When the door 2 is closed, the first shaft 331 is located at the first end of the first slot 341, and the second shaft 332 is located at the third end of the second slot 342.

[0120] refer to Figure 9 When the door body 2 is opened at the first angle, the first shaft 331 is located between the first end and the second end of the first slot 341 and is close to the first end; the second shaft 332 is located between the third end and the fourth end of the second slot 342 and is close to the third end.

[0121] refer to Figure 10 When the door body 2 is opened to the second angle, the first shaft 331 is located between the first end and the second end of the first slot 341 and is close to the second end; the second shaft 332 is located between the third end and the fourth end of the second slot 342 and is close to the fourth end.

[0122] refer to Figure 11When the door body 2 is opened at the third angle, the first shaft 331 is located at the second end of the first slot 341 ; the second shaft 332 is located at the fourth end of the second slot 342 .

[0123] The first angle is smaller than the second angle, and the second angle is smaller than the third angle. The third angle is the maximum angle that the door body 2 can open.

[0124] Some embodiments further provide a refrigerator comprising the above-mentioned cabinet assembly.

[0125] The cabinet assembly includes a cabinet 1 and a door 2. When the door 2 is opened or closed, the position of the door around the hinge axis can be changed according to different opening and closing angles to ensure that the third side wall 23 of the door 2 does not exceed the outermost side of the refrigerator cabinet 1, which is conducive to the installation of the built-in refrigerator.

[0126] In addition to the above-mentioned refrigerator, other household appliances, such as microwave ovens, ovens, etc. can also adopt the cabinet assembly provided by the embodiment of the present disclosure.

[0127] Based on the above-mentioned embodiments of the present disclosure, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.
