[0004]诸如对于嵌入式冰箱而言,一般是将冰箱放在橱柜内,要求在开门的过程中,门体的边角部不能过多的超出箱体的侧壁面,否则会导致在开关门过程中,门体的边角部会碰到冰箱侧边的橱柜,直接影响用户使用,体验感较差

Benefits of technology

[0026] The refrigerator in this embodiment uses a hinge to connect the cabinet and the door, allowing the door to rotate relative to the cabinet to open or close the refrigerator's storage compartment. A first shaft on the door engages with a first groove on the hinge plate, and a second shaft on the door engages with a second groove on the hinge plate. This allows the door to rotate about the second shaft as its axis of rotation when rotating from the closed state to a first preset angle, while the first shaft slides relative to the first groove. Similarly, when the door opens from the first preset angle to a second preset angle, the door can rotate about the first shaft as its axis of rotation, and the second shaft can slide relative to the second groove. This can also be understood as the door rotating to a certain angle on a fixed axis, then switching to another axis for fixed-axis rotation. In other words, the door undergoes two stages of diameter-changing motion during rotation. Furthermore, since the first axis is located between the cabinet and the second axis, during the process of the door rotating from the closed state to the second preset angle, the radius of rotation of the corner of the door rotating around the second axis is smaller than the radius of rotation of the corner of the door rotating around the first axis. Thus, the corner of the door begins to adjust the rotation center of the door when it extends a small distance beyond the side wall of the cabinet, so as to avoid the cabinet or wall on the side of the refrigerator and make the door move smoothly when it opens.

Description

Technical Field

[0001] This application pertains to the field of home appliances, and in particular relates to a refrigerator. Background Technology

[0002] Refrigerators are common household appliances used in daily life, mainly for keeping fruits, vegetables and other foods fresh at low temperatures, such as freezing or refrigeration.

[0003] In related technologies, the refrigerator body is typically hinged to one end of the refrigerator door, allowing the user to open the refrigerator body by rotating around the hinged end. Most refrigerator door hinges are single-axis designs, where the door rotates around the hinge axis through a hinge shaft. With this type of hinge, the corner of the door may extend beyond the side of the refrigerator body during opening. If the space on the side of the refrigerator is limited, the corner of the door may hit the side wall.

[0004] For built-in refrigerators, which are typically placed inside cabinets, the corners of the door should not extend too far beyond the side wall of the cabinet when opening or closing. Otherwise, the corners of the door may hit the cabinet on the side of the refrigerator, directly affecting the user experience and resulting in a poor user experience. Summary of the Invention

[0005] This application provides a refrigerator in which the door does not extend excessively beyond the side wall of the refrigerator body when opened.

[0006] This application provides a refrigerator, including:

[0007] Box;

[0008] The door is rotatable relative to the housing. The door is provided with a first shaft and a second shaft. When the door is closed, the first shaft is located between the housing and the second shaft.

[0009] A hinge plate is connected to the housing, and the hinge plate is provided with a first sliding groove and a second sliding groove; the first shaft is inserted into the first sliding groove, and the second shaft is inserted into the second sliding groove;

[0010] During the process of the door rotating from the closed state to the first preset angle, the door can rotate about the second shaft as the axis of rotation, and the first shaft can slide relative to the first slide groove;

[0011] During the process of the door opening from the first preset angle to the second preset angle, the door can rotate about the first shaft as the axis of rotation, and the second shaft can slide relative to the second slide groove.

[0012] Optionally, the first chute includes a first positioning segment and a first trajectory segment that are interconnected.

[0013] During the process of the door rotating from the closed state to the first preset angle, the first shaft slides relative to the first trajectory segment and slides to the first positioning segment;

[0014] During the process of the door opening from the first preset angle to the second preset angle, the first shaft can rotate relative to the first positioning segment.

[0015] Optionally, the second chute includes a second positioning segment and a second trajectory segment that are interconnected.

[0016] When the door is in the closed state, the second shaft is located in the second positioning section. During the process of the door rotating from the closed state to the first preset angle, the second shaft can rotate relative to the second positioning section.

[0017] During the process of the door opening from the first preset angle to the second preset angle, the second shaft can slide relative to the second trajectory segment.

[0018] Optionally, the second slide rail further includes a limiting section communicating with the second track segment. The limiting section is located at one end of the second track segment away from the second positioning segment. During the process of the door opening from the second preset angle to the third preset angle, the door can rotate about the first shaft as the rotation axis, and the second shaft can slide relative to the second track segment to abut against the limiting section.

[0019] Optionally, both the first trajectory segment and the second trajectory segment are arc-shaped grooves, with the first positioning segment located at the center of the second trajectory segment and the second positioning segment located at the center of the first trajectory segment.

[0020] Optionally, the door body includes a rear wall surface, a front wall surface, and a side wall surface near the hinge plate. The rear wall surface faces the housing, and the rear wall surface is opposite to the front wall surface. The side wall surface is connected to the rear wall surface and the front wall surface.

[0021] The distance between the axis of the second shaft and the front wall of the door is L1, the distance between the axis of the second shaft and the side wall of the door is L2, and the distance between the side wall of the door and the wall or cabinet wall is L3.

[0022] Optionally, the distance between the axis of the second shaft and the front wall of the door is set between 8.5 mm and 10.5 mm, and the distance between the axis of the second shaft and the side wall of the door is set between 14 mm and 17 mm.

[0023] Optionally, the center distance between the first shaft and the second shaft is between 9.5 mm and 12.5 mm, and the second shaft is further away from the side wall of the door than the first shaft.

[0024] Optionally, the angle between the extension of the line connecting the center of the first shaft and the center of the second shaft and the side wall of the door body is between 15 degrees and 25 degrees.

[0025] Optionally, the refrigerator further includes a door hinge plate, which is detachably mounted on the door, and the first shaft and the second shaft are mounted on the door hinge plate.

[0026] The refrigerator in this embodiment uses a hinge to connect the cabinet and the door, allowing the door to rotate relative to the cabinet to open or close the refrigerator's storage compartment. A first shaft on the door engages with a first groove on the hinge plate, and a second shaft on the door engages with a second groove on the hinge plate. This allows the door to rotate about the second shaft as its axis of rotation when rotating from the closed state to a first preset angle, while the first shaft slides relative to the first groove. Similarly, when the door opens from the first preset angle to a second preset angle, the door can rotate about the first shaft as its axis of rotation, and the second shaft can slide relative to the second groove. This can also be understood as the door rotating to a certain angle on a fixed axis, then switching to another axis for fixed-axis rotation. In other words, the door undergoes two stages of diameter-changing motion during rotation. Furthermore, since the first axis is located between the cabinet and the second axis, during the process of the door rotating from the closed state to the second preset angle, the radius of rotation of the corner of the door rotating around the second axis is smaller than the radius of rotation of the corner of the door rotating around the first axis. Thus, the corner of the door begins to adjust the rotation center of the door when it extends a small distance beyond the side wall of the cabinet, so as to avoid the cabinet or wall on the side of the refrigerator and make the door move smoothly when it opens.

[0048] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0049] In the description of the embodiments of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0050] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a refrigerator provided in an embodiment of this application. Figure 2 for Figure 1 The image shows a cross-sectional view of a refrigerator. This application provides a refrigerator that may include a body 10, a door 20, and a hinge plate 30. The body 10 has storage compartments, such as a freezer compartment, a refrigerator compartment, or a wide-range variable temperature compartment. Of course, in some optional embodiments, the storage compartments may also be defrosting compartments or sterilization compartments with defrosting functions; this application does not limit this. The door 20 is used to open or close the storage compartments of the body 10. The door 20 can be hinged to the body 10 via the hinge plate 30. Specifically, hinge plates 30 can be provided at the upper and lower parts of the body 10, and the hinge plates at the upper and lower parts of the body 10 cooperate with the door 20 to allow the door 20 to rotate smoothly.

[0051] The storage compartment has an opening or access port at its front end for placing food into or retrieving food from the storage compartment. The box body 10 includes an opening end face 11 surrounding the opening of the storage compartment.

[0052] It is understood that the cabinet 10 includes a first side wall 12 and a second side wall 13 (i.e., the right side wall and the left side wall of the cabinet 10) arranged opposite to each other. A hinge plate 30 is disposed on the cabinet 10 and near the first side wall 12. Alternatively, the hinge plate 30 is disposed on the cabinet 10 and near the second side wall 13. Of course, for a double-door refrigerator, the hinge plate 30 is provided near both the first side wall 12 and the second side wall 13.

[0053] The door 20 includes a rear wall 211, a front wall 212, and a side wall 213 near the hinge plate 30. When the door 20 is closed, the rear wall 211 faces the opening end face 11 of the housing 10. The rear wall 211 is opposite to the front wall 212, and the side wall 213 connects to both. When the hinge plate 30 is located on the right side of the housing 10, the right side of the door 20 is the side wall 213; when the hinge plate 30 is located on the left side of the housing 10, the left side of the door 20 is the side wall 213. The front wall surface 212 and the side wall surface 213 of the door body 20 intersect to form the first side edge 214, or in other words, the intersection of the front wall surface 212 and the side wall surface 213 forms the corner of the door body 20. It should be noted that when both the front wall surface 212 and the side wall surface 213 are planar, the intersection line of the two planes is theoretically the first side edge 214. However, in the actual processing, the intersection of the front wall surface 212 and the side wall surface 213 will be transitioned by a rounded corner, which forms a curved surface. A vertical line extending along the length of the door body 20 and located in the middle of the curved surface can represent the first side edge 214.

[0054] It should be noted that in the relevant technology, when the door is rotated, the corner of the door (or the first side edge) will extend too far beyond the side wall of the refrigerator. If the refrigerator is close to the side wall of the wall or cabinet, the corner of the door will hit the side wall or cabinet of the refrigerator, directly affecting the user's use.

[0055] Based on this, please refer to Figures 3 to 8 , Figure 3 for Figure 1 Exploded view of the middle door and hinge plate. Figure 4 for Figure 3 A schematic diagram of the middle hinge plate. Figure 5 This is a schematic diagram of the structure of the first and second slide grooves that mate with the first and second shafts. Figure 6 for Figure 2 A magnified view of a portion of the structure shown at the hinge. Figure 7 for Figure 6 The diagram shows the structure when the door is opened to the first preset angle. Figure 8 for Figure 6The diagram shows the structure of the door when it is opened to a second preset angle. The door 20 is provided with a first shaft 22 and a second shaft 23. When the door 20 is closed, the first shaft 22 is located between the cabinet 10 and the second shaft 23. A hinge plate 30 is connected to the cabinet 10, and the hinge plate 30 is provided with a first sliding groove 31 that mates with the first shaft 22 and a second sliding groove 32 that mates with the second shaft 23. Specifically, the first shaft 22 is located between the refrigerator's opening end face 11 and the second shaft 23; in other words, the first shaft 22 is closer to the refrigerator's opening end face 11 than the second shaft 23. It can be understood that the first shaft 22 is inserted into the first sliding groove 31, and the second shaft 23 is inserted into the second sliding groove 32. During the process of the door 20 rotating from the closed state to the first preset angle a, the door 20 can rotate about the second shaft 23 as its axis of rotation, and the first shaft 22 can slide relative to the first sliding groove 31. During the process of the door 20 opening from the first preset angle a to the second preset angle b, the door 20 can rotate about the first shaft 22 as the axis of rotation, and the second shaft 23 can slide relative to the second slide groove 32. It can be understood that the first preset angle a is greater than the second preset angle b. Through the cooperation of the first shaft 22 and the first slide 31, and the cooperation of the second shaft 23 and the second slide 32, the door 20 can rotate to a certain angle on a fixed axis, and then switch to another shaft for fixed-axis rotation. That is, the door 20 undergoes two stages of diameter change during rotation. Since the first shaft 22 is located between the cabinet 10 and the second shaft 23, during the process of the door 20 rotating from the closed state to the second preset angle b, the rotation radius of the corner of the door 20 when rotating with the second shaft 23 as the axis is smaller than the rotation radius of the corner of the door 20 when rotating with the first shaft 22 as the axis. Thus, when the corner of the door 20 exceeds the side wall of the cabinet 10 by a small distance, the rotation center of the door 20 begins to adjust (at this time, the door 20 rotates with the first shaft 22 as the rotation axis) so as to avoid the cabinet or wall on the side of the refrigerator and make the door 20 move smoothly when opening.

[0056] Understandably, the refrigerator has hinge plates 30 at its upper and lower ends. Corresponding to the positions of the hinge plates 30, the upper and lower ends of the door 20 are each provided with a first shaft 22 and a second shaft 23. Furthermore, the first shafts 22 at the upper and lower ends of the door 20 are vertically aligned, and the second shafts 23 at the upper and lower ends of the door 20 are also vertically aligned, so that the movement of the upper and lower ends of the door 20 is consistent, thereby making the opening and closing of the door 20 smoother.

[0057] It is understandable that the hinge plate 30 can be fixed to the refrigerator body 10 by screw connection. The first slide groove 31 and the second slide groove 32 are provided on the hinge plate 30.

[0058] The refrigerator may also include a door hinge plate 40, which is detachably mounted on the door body 20. A first shaft 22 and a second shaft 23 are mounted on the door hinge plate 40. For example, the first shaft 22 and the second shaft 23 may be integrally formed with the door hinge plate 40. Alternatively, the first shaft 22 and the second shaft 23 may be separate structures from the door hinge plate 40 and then assembled onto the connecting plate 33. The door hinge plate 40 may be fixed to the door body 20 by screws for easy assembly and disassembly.

[0059] It is also understandable that, in order for the first shaft 22 and the second shaft 23 to rotate or slide more smoothly in their respective grooves, the first shaft 22 and the second shaft 23 are rotatably connected to the door pivot plate 40.

[0060] To more clearly illustrate the connection relationship between the first shaft 22 and the first slide groove 31, and the connection relationship between the second shaft 23 and the second slide groove 32, the specific structures of the first shaft 22, the first slide groove 31, the second shaft 23 and the second slide groove 32 will be described in detail below with reference to the accompanying drawings.

[0061] Please see Figures 4 to 8 The first slide groove 31 is connected to the second slide groove 32. The depth of the first slide groove 31 is greater than the depth of the second slide groove 32. The first shaft 22 extends into the first slide groove 31, and the second shaft 23 extends into the second slide groove 32. In this way, the positions of the first slide groove 31 and the second slide groove 32 can be made more compact.

[0062] The first slide groove 31 includes a first positioning section 311 and a first trajectory section 312 that are interconnected. The first trajectory section 312 includes a first groove wall that contacts the first shaft 22. During the process of the door 20 rotating from the closed state to the first preset angle a, the door 20 can rotate about the second shaft 23 as the axis of rotation. At this time, the first shaft 22 can slide relative to the first trajectory section 312 and slide to the first positioning section 311. During the process of the door 20 opening from the first preset angle a to the second preset angle b, the first shaft 22 can rotate relative to the first positioning section 311. That is, at this time, the door 20 can rotate about the first shaft 22 as the axis of rotation, and the second shaft 23 can slide relative to the second slide groove 32.

[0063] Understandably, the second slide 32 includes a second positioning section 321 and a second trajectory section 322 that are interconnected. The second trajectory section 322 includes a second groove wall that contacts the second shaft 23. When the door 20 is in the closed state, the second shaft 23 is located in the second positioning section 321. During the process of the door 20 rotating from the closed state to the first preset angle a, the second shaft 23 can rotate relative to the second positioning section 321. At this time, the first shaft 22 can slide relative to the first trajectory section 312 and slide to the first positioning section 311. During the process of the door 20 opening from the first preset angle a to the second preset angle b, the first shaft 22 can rotate relative to the first positioning section 311. That is, at this time, the door 20 can rotate about the first shaft 22 as the axis of rotation, and the second shaft 23 can slide relative to the second trajectory section 322.

[0064] Thus, as the door 20 rotates from the closed state to the first preset angle a, the second shaft 23 rotates relative to the second positioning segment 321, and the door 20 can rotate with the second shaft 23 as the axis of rotation. The first shaft 22 slides relative to the first trajectory segment 312 to the first positioning segment 311. At this time, as the door 20 continues to rotate, as the door 20 opens from the first preset angle a to the second preset angle b, the first shaft 22 rotates relative to the first positioning segment 311, and the door 20 can rotate with the first shaft 22 as the axis of rotation. The second shaft 23 slides relative to the second trajectory segment 322. That is, when the door 20 rotates from the closed state to the first preset angle a, the door 20 rotates around the second shaft 23 as the rotation axis. When the door 20 rotates from the first preset angle a to the second preset angle b, the door 20 rotates around the first shaft 22 as the rotation axis. The door 20 undergoes two stages of diameter change during the rotation process. In this way, when the corner of the door 20 exceeds the side wall of the cabinet 10 by a small distance, the rotation center of the door 20 begins to be adjusted so as to avoid the cabinet or wall on the side of the refrigerator and make the door 20 move smoothly when it is opened.

[0065] The first trajectory segment 312 and the second trajectory segment 322 are both arc-shaped grooves, and the arc-shaped first trajectory segment 312 and the second trajectory segment 322 serve as guides. The first positioning segment 311 is located at the center of the second trajectory segment 322, and the second positioning segment 321 is located at the center of the first trajectory segment 312.

[0066] Understandable, please combine them. Figure 9 , Figure 9 for Figure 6Enlarged view at point A. When the door 20 rotates from the closed state to the first preset angle α, that is, when the door 20 rotates around the second shaft 23, it is necessary to ensure that the first side edge 214 (or the corner of the door 20) does not collide with the wall or cabinet wall. Based on this, the distance between the axis of the second shaft 23 and the front wall surface 212 of the door is denoted as L1, the distance between the axis of the second shaft 23 and the side wall surface 213 of the door is denoted as L2, and the distance between the side wall surface 213 of the door and the wall or cabinet wall is denoted as L3. Alternatively, when the door 20 is in the closed state, the distance between the center of the groove of the second positioning segment 321 and the front wall surface 212 of the door is denoted as L1, and the distance between the center of the groove of the second positioning segment 321 and the side wall surface 213 of the door is denoted as L2. In this way, it can be ensured that when the door 20 rotates around the second axis 23, the arc trajectory of the first side edge 214 will not interfere with the wall or cabinet wall.

[0067] For example, in the case of a built-in refrigerator, the distance between the side panel of the built-in cabinet and the side wall of the refrigerator is relatively small, generally 2 mm to 4 mm. Based on this, to improve adaptability without significantly altering the existing refrigerator door 20 structure, the distance L1 between the axis of the second shaft 23 and the front wall surface 212 of the door can be set between 8.5 mm and 10.5 mm, and the distance L2 between the axis of the second shaft 23 and the side wall surface 213 of the door can be set between 14 mm and 17 mm. Alternatively, when the door 20 is closed, the distance L1 between the center of the groove of the second positioning section 321 and the front wall surface 212 of the door can be set between 8.5 mm and 10.5 mm, and the distance L2 between the center of the groove of the second positioning section 321 and the side wall surface 213 of the door can be set between 14 mm and 17 mm. In this way, without significantly altering the existing refrigerator door structure 20, such as without changing the thickness of the door 20, it is possible to ensure that the arc trajectory of the first side edge 214 will not interfere with the wall or cabinet wall when the door 20 rotates around the second axis 23.

[0068] For example, the distance L1 between the axis of the second shaft 23 and the front wall 212 of the door can be set to 9 mm, and the distance L2 between the axis of the second shaft 23 and the side wall 213 of the door can be set to 16 mm. Since a radius of 1 mm is usually machined at the first side edge 214 (the corner of the door 20), the first side edge 214 can be made to extend beyond the side wall of the box 10 by no more than 2 mm during the rotation of the door 20.

[0069] Understandably, after the door 20 moves to the first preset angle a around the second axis 23, it then moves to the second preset angle b around the first axis 22, thus achieving a two-stage diameter change movement of the door 20. The center distance between the first axis 22 and the second axis 23 is set between 9.5 mm and 12.5 mm, and the second axis 23 is further away from the door side wall 213 than the first axis 22. Thus, when the door 20 switches to moving around the first axis 22, this arrangement of the first axis 22 prevents interference between the arc-shaped trajectory of the first side edge 214 and the wall or cabinet wall during the rotation of the door 20. Furthermore, when the door 20 moves to the second preset angle b, the door 20 will not obstruct the pulling out of the drawers inside the storage room.

[0070] Among them, such as Figure 6 As shown, the angle d between the extension of the line connecting the center of the first shaft 22 and the center of the second shaft 23 and the side wall 213 of the door body is between 15 degrees and 25 degrees, so that the door body 20 can move more smoothly when it undergoes two-stage diameter change movements.

[0071] To facilitate understanding, the following will provide examples based on the specific rotation angle of the door body 20.

[0072] For example, the first preset angle a can be 45 degrees and the second preset angle b can be 90 degrees. Of course, in other embodiments, the first preset angle a can be 30 degrees or 35 degrees or other angles, and the second preset angle b can be 80 degrees or 85 degrees or other angles. This application embodiment does not impose any restrictions here.

[0073] This application embodiment uses a first preset angle a of 45 degrees and a second preset angle b of 90 degrees as an example for illustration. When the door 20 opens from the closed state to an angle of 45 degrees, the second shaft 23 rotates relative to it within the second positioning segment 321. The door 20 can rotate about the second shaft 23 as its axis of rotation. The first shaft 22 slides relative to the first trajectory segment 312 to the first positioning segment 311. If the door 20 continues to rotate, and the door 20 opens from a 45-degree angle to a 90-degree angle, the first shaft 22 rotates relative to it within the first positioning segment 311. At this time, the door 20 can rotate about the first shaft 22 as its axis of rotation, and the second shaft 23 slides relative to the second trajectory segment 322.

[0074] In some embodiments, the door 20 can also be opened to a greater than a second preset angle b (such as 90 degrees). At this time, the refrigerator can be placed in a location with a larger storage space. It is understood that when the space is large, there is no need to consider the problem that the door 20 will collide with the surrounding wall when it is rotated to a greater than 90 degrees.

[0075] For example, please refer to Figure 10 and combined Figure 5 , Figure 10 for Figure 6 The diagram shows the structure of the door when it is opened to the third preset angle. The door 20 can be opened to the third preset angle c, which is greater than the second preset angle b, such as 120 degrees. The second slide 32 may also include a limiting segment 323 connected to the second track segment 322. The limiting segment 323 is located at the end of the second track segment 322 away from the second positioning segment 321. During the process of the door 20 opening from the second preset angle b to the third preset angle c, the door 20 can rotate about the first shaft 22 as the axis of rotation, and the second shaft 23 can slide relative to the second track segment 322 until it abuts against the wall of the limiting segment 323. In this way, the limiting effect of the limiting segment 323 can restrict the door 20 from continuing to rotate about the first shaft 22 as the axis of rotation.
