Description

Refrigerators and Built-in Refrigeration Units

[0001] This application claims priority to Chinese Patent Application No. 202410926382.4, filed on July 11, 2024, entitled "Refrigerator and Built-in Refrigerator Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of household appliance technology, and in particular to a refrigerator and a built-in refrigerator device. Background Technology

[0003] 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. Technical issues

[0004] In response to current home decoration styles, some families pursue a unified style, which requires placing the refrigerator in the cabinet to form a so-called built-in refrigerator unit. Built-in refrigerator units require that the corners of the door cannot extend too far beyond the side wall of the refrigerator body during the opening and closing process. Otherwise, the corners of the door will hit the cabinet on the side of the refrigerator during the opening and closing process, which will directly affect the user experience and result in a poor user experience. Technical solutions

[0005] Based on this, embodiments of this application provide a refrigerator and an embedded refrigerator device.

[0006] In a first aspect, embodiments of this application provide a refrigerator, comprising:

[0007] The housing has a first end face;

[0008] The door is rotatably connected to the box body. The door has a second end face that is perpendicular to the first end face. The second end face is provided with a first sliding groove and a second sliding groove.

[0009] A hinge is connected to the housing. The hinge has a first shaft and a second shaft. The first shaft is inserted into the first slide groove, and the second shaft is inserted into the second slide groove.

[0010] The edge of the second end face of the door includes an inner edge and an outer edge that are arranged opposite to each other, as well as a first side edge and a second side edge that are arranged opposite to each other. The inner edge is located close to the box body, the outer edge is located away from the box body, and the first side edge is located close to the hinge.

[0011] The angle between the inner edge of the door and the first end face of the box is the opening angle. When the opening angle increases from zero to the maximum opening angle, the trajectory formed by the axis of the first shaft moving in the first slide groove is the first trajectory, and the trajectory formed by the axis of the second shaft moving in the second slide groove is the second trajectory. The second trajectory is located on the side of the first trajectory closer to the outer edge. The first trajectory includes a first extension segment and a second extension segment connected in sequence. The first extension segment extends away from the outer edge and closer to the first side, and the second extension segment extends closer to the outer edge and closer to the first side. The second trajectory includes a third extension segment and a fourth extension segment connected in sequence. The third extension segment extends away from the outer edge and closer to the first side, and the fourth extension segment extends closer to the outer edge and closer to the first side.

[0012] Secondly, embodiments of this application provide an embedded refrigerator device, including a cabinet and a refrigerator, wherein the cabinet has an inner cavity, and the refrigerator is accommodated in the inner cavity of the cabinet, and the refrigerator is a refrigerator as described above. Beneficial effects

[0013] The refrigerator provided in this application embodiment can be used alone or embedded in a cabinet. The refrigerator includes a cabinet body, a door body, and a hinge. The hinge has a first shaft and a second shaft. The second end face of the door body is provided with a first slide groove and a second slide groove. During the process of increasing the door opening angle from zero to the maximum door opening angle, the first trajectory formed by the axis of the first shaft moving in the first slide groove first extends away from the outside and closer to the first side, and then extends closer to the outside and closer to the first side. The second trajectory formed by the axis of the second shaft moving in the second slide groove is located on the side of the first trajectory closer to the outside. The second trajectory first extends away from the outside and closer to the first side, and then extends closer to the outside and closer to the first side. Through the above design, the rotation center of the door body gradually changes during the opening and closing process, so as to avoid the refrigerator door body touching the cabinet and ensure that the door body moves smoothly during opening or closing.

Embodiments of the present invention

[0024] 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.

[0025] Please refer to Figures 1 to 5. This application provides a refrigerator 110, which includes a cabinet 10, a door 20, and a hinge 30.

[0026] Please refer to Figure 1. The box 10 has a first end face 101 with an opening for taking items out of the box 10.

[0027] Please refer to Figure 1. The door 20 is rotatably connected to the box 10. The door 20 is used to cover the opening on the first end face 101 of the box 10. The door 20 has a second end face 201 perpendicular to the first end face 101. The second end face 201 is provided with a first sliding groove 25 and a second sliding groove 26.

[0028] Please refer to Figures 1, 2 and 3. The hinge 30 is connected to the housing 10. The hinge 30 has a first shaft 31 and a second shaft 32. The first shaft 31 is inserted into the first slide groove 25, and the second shaft 32 is inserted into the second slide groove 26.

[0029] Please refer to Figure 1. The edge of the second end face 201 of the door body 20 includes an inner edge 21 and an outer edge 23 arranged opposite to each other, as well as a first side edge 22 and a second side edge 24 arranged opposite to each other. The inner edge 21 is located close to the box body 10, the outer edge 23 is located away from the box body 10, the first side edge 22 is located close to the hinge 30, and the outer edge 23 intersects the first side edge 22 at point M.

[0030] Please refer to Figure 1. The inner edge 21, the first side edge 22, the outer edge 23, and the second side edge 24 are connected end to end in sequence.

[0031] Please refer to Figure 4. The angle between the inner edge 21 of the door body 20 and the first end face 101 of the box body 10 is the opening angle. When the opening angle increases from zero to the maximum opening angle, the trajectory formed by the axis of the first shaft 31 moving in the first slide groove 25 is the first trajectory, and the trajectory formed by the axis of the second shaft 32 moving in the second slide groove 26 is the second trajectory. The second trajectory is located on the side of the first trajectory closer to the outer edge 23. The first trajectory includes a first extension segment and a second extension segment connected in sequence. The first extension segment extends away from the outer edge 23 and closer to the first side edge 22, and the second extension segment extends closer to the outer edge 23 and closer to the first side edge 22. The second trajectory includes a third extension segment and a fourth extension segment connected in sequence. The third extension segment extends away from the outer edge 23 and closer to the first side edge 22, and the fourth extension segment extends closer to the outer edge 23 and closer to the first side edge 22.

[0032] For example, in this embodiment of the application, the maximum opening angle of the door 20 is 120°.

[0033] It is understood that in this embodiment of the application, the door 20 is hinged to the cabinet 10 of the refrigerator 110 by the hinge 30, and the door 20 can rotate smoothly through the cooperation of the hinge 30 and the door 20.

[0034] Referring to Figure 3, the hinge 30 also includes a connecting plate 33, which is fixed to the cabinet 10 of the refrigerator 110. For example, the connecting plate 33 can be fixed to the cabinet 10 of the refrigerator 110 by screws 50. The first shaft 31 and the second shaft 32 are both connected to the connecting plate 33. Exemplarily, the first shaft 31 and the second shaft 32 can be integrally formed with the connecting plate 33, or the first shaft 31 and the second shaft 32 can be made into separate structures with the connecting plate 33 and then assembled onto the connecting plate 33.

[0035] Please refer to Figure 3. The connecting plate 33 may include a bottom plate and a side plate that are perpendicular to each other and connected. The first shaft 31 and the second shaft 32 are both fixed to the bottom plate. The side plate can be fixed to the cabinet 10 of the refrigerator 110 by screws 50.

[0036] For example, in order to make the first shaft 31 and the second shaft 32 slide more smoothly in the corresponding slide groove, the first shaft 31 and the second shaft 32 can be rotatably connected to the connecting plate 33.

[0037] Please refer to Figures 1 to 4. The first shaft 31 and the second shaft 32 can both be cylinders. In this case, it means that the center line of the first shaft 31 is the center of the cross-section of the first shaft 31, and the center line of the second shaft 32 is the center of the cross-section of the second shaft 32.

[0038] For example, the first slide groove 25 and the second slide groove 26 can be directly machined on the door body 20. In some embodiments, the first slide groove 25 and the second slide groove 26 can also be machined on the slide groove member first, and then the slide groove member is installed on the door body 20, so that the first slide groove 25 and the second slide groove 26 are formed on the second end face 201 of the door body 20.

[0039] Understandably, the door 20 has two opposing second end faces 201 (i.e., an upper end face and a lower end face). At least one of the positions on the refrigerator body 10 corresponding to the upper and lower end faces of the door 20 is connected to the hinge 30. At least one of the positions on the upper and lower end faces of the door 20 is provided with a first sliding groove 25 and a second sliding groove 26. When both the upper and lower end faces of the door 20 are provided with the first sliding groove 25 and the second sliding groove 26, the first sliding groove 25 on the upper end face corresponds to the first sliding groove 25 on the lower end face, and the second sliding groove 26 on the upper end face corresponds to the second sliding groove 26 on the lower end face, thereby making the movement of the upper and lower ends of the door 20 consistent, thus making the opening or closing of the door 20 smoother.

[0040] For example, the refrigerator 110 has a storage compartment inside the cabinet 10, such as a freezer compartment, a refrigerator compartment, or a variable temperature compartment.

[0041] Please refer to Figures 1 and 2. A door closer 40 is also installed on the door 20. The door closer 40 can automatically close the door 20 when it is open and without external support, so as to realize the automatic closing function when the user forgets to close the refrigerator 110 door. This can prevent the temperature inside the refrigerator 10 from rising when the refrigerator 110 door is open, which could lead to food spoilage.

[0042] The refrigerator 110 provided in this application embodiment can be used alone or embedded in a cabinet. The refrigerator 110 includes a cabinet body 10, a door body 20, and a hinge 30. The hinge 30 has a first shaft 31 and a second shaft 32. The second end face 201 of the door body 20 is provided with a first sliding groove 25 and a second sliding groove 26. During the process of increasing the door opening angle from zero to the maximum door opening angle, the first trajectory formed by the axis of the first shaft 31 moving in the first sliding groove 25 first extends away from the outer edge 23 and closer to the first side edge 22, and then extends closer to the outer edge 23 and closer to the first side edge 22. The second track formed by the movement of the axis of the second shaft 32 within the second slide groove 26 extends in the direction of the first side 22. The second track is located on the side of the first track closer to the outer edge 23. The second track first extends away from the outer edge 23 and closer to the first side 22, and then extends closer to the outer edge 23 and closer to the first side 22. Through the above design, the rotation center of the door 20 gradually changes during the opening and closing process, so as to avoid the refrigerator 110 door 20 touching the cabinet, and to ensure that the door 20 moves smoothly during opening or closing.

[0043] Please refer to Figure 6 and Figure 4. When the door opening angle is zero, the point where the center line of the first shaft 31 is located in the first slide groove 25 is point O1, and the point where the center line of the second shaft 32 is located in the second slide groove 26 is point Q1. The distance between point O1 and the first side 22 is greater than the distance between point Q1 and the first side 22.

[0044] For example, the distance between point O1 and the outer edge 23 can be greater than, equal to or less than the distance between point Q1 and the outer edge 23.

[0045] Please refer to Figures 6 and 7, and also refer to Figure 4. When the door opening angle increases from zero to 45°, the axis of the first shaft 31 moves from point O1 to point O2 in the first slide groove 25, while the axis of the second shaft 32 remains stationary at point Q1 in the second slide groove 26.

[0046] That is to say, when the door opening angle is 45°, the position of the axis of the first shaft 31 in the first slide groove 25 is point O2, and the position of the axis of the second shaft 32 in the second slide groove 26 is point Q1;

[0047] The distance between point O2 and the first side 22 is less than the distance between point O1 and the first side 22, and the distance between point O2 and the outer side 23 is greater than the distance between point O1 and the outer side 23.

[0048] It should be noted that during the process of increasing the door opening angle from zero to 45°, since the center line of the second shaft 32 remains stationary at point Q1 in the second slide groove 26, the center line of the first shaft 31 moves from point O1 to point O2 in the first slide groove 25. That is to say, during the process of increasing the door opening angle from zero to 45°, the rotation center of the door body 20 is point Q1, and the movement trajectory of the center line of the first shaft 31 (the trajectory segment from O1 to O2) is an arc.

[0049] Please refer to Figures 7 and 8, and also to Figure 4. When the door opening angle increases from 45° to 90°, the axis of the first shaft 31 moves from point O2 to point O3 within the first slide groove 25, and the axis of the second shaft 32 moves from point Q1 to point Q2 within the second slide groove 26; the O1~O2~O3 trajectory segment is the first extension segment of the first trajectory; the Q1~Q2 trajectory segment is the third extension segment of the second trajectory.

[0050] That is to say, when the door opening angle is 90°, the position of the axis of the first shaft 31 in the first slide groove 25 is point O3, and the position of the axis of the second shaft 32 in the second slide groove 26 is point Q2.

[0051] Wherein, the distance between point O3 and the first side 22 is less than the distance between point O2 and the first side 22, and the distance between point O3 and the outer side 23 is greater than the distance between point O2 and the outer side 23;

[0052] The distance between point Q2 and the first side 22 is less than the distance between point Q1 and the first side 22, and the distance between point Q2 and the outer side 23 is greater than the distance between point Q1 and the outer side 23.

[0053] Please refer to Figures 8 and 9, and also to Figure 4. When the door opening angle increases from 90° to 120°, the axis of the first shaft 31 moves from point O3 to point O4 within the first slide groove 25, and the axis of the second shaft 32 moves from point Q2 to point Q3 within the second slide groove 26; the O3-O4 trajectory segment is the second extension of the first trajectory; the Q2-Q3 trajectory segment is the fourth extension of the second trajectory.

[0054] That is to say, when the opening angle is 120°, the position of the axis of the first shaft 31 in the first slide groove 25 is point O4, and the position of the axis of the second shaft 32 in the second slide groove 26 is point Q3.

[0055] The distance between point O4 and the first side 22 is less than the distance between point O3 and the first side 22, and the distance between point O4 and the outer side 23 is less than the distance between point O3 and the outer side 23;

[0056] The distance between point Q3 and the first side 22 is less than the distance between point Q2 and the first side 22; the distance between point Q3 and the outer side 23 is less than the distance between point Q2 and the outer side 23.

[0057] Please refer to Figure 4. The trajectory of the axis of the first shaft 31 between O3 and O4 is an arc, and the trajectory of the axis of the second shaft 32 between Q2 and Q3 is an arc. The arcs O3 to O4 and Q2 to Q3 share the same center O0.

[0058] It is understandable that when the axis of the first shaft 31 moves on the arc O3 to O4 and the axis of the second shaft 32 moves on the arc Q2 to Q3, since the arcs O3 to O4 and Q2 to Q3 share the same center O0, it means that during the process of the door opening angle of the door 20 increasing from 90° to 120°, the rotation center of the door 20 is fixed at point O0. That is, during this process, the door 20 always rotates around point O0.

[0059] Please refer to Figure 4. The distance between point O4 and the first side 22 is less than the distance between point Q2 and the first side 22, and the distance between point O4 and the outer side 23 is greater than the distance between point Q2 and the outer side 23.

[0060] Please refer to Figures 6 to 9, and also refer to Figure 4. During the process of the door body 20 increasing from zero to the maximum opening angle (120°), the first trajectory of the first shaft 31 is the trajectory segment O1~O2~O3~O4, and the second trajectory of the second shaft 32 is the trajectory segment Q1~Q2~Q3.

[0061] Please refer to Figures 6 to 9. When the axis of the first shaft 31 moves within the trajectory segment O1~O2~O3~O4, and the axis of the second shaft 32 moves within the trajectory segment Q1~Q2~Q3, the door 20 first rotates to a position where the first side 22 is almost parallel to the first end face 101 of the cabinet 10 (see Figure 8). Then, the door 20 gradually moves away from the cabinet 10 (see Figures 8 to 9). It can be understood that when the door 20 gradually moves away from the cabinet 10, the point M on the door 20 also gradually moves away from the cabinet 10. That is to say, during the rotation of the door 20, the point M on the door 20 does not rotate along the arc trajectory, thereby avoiding the situation where the door 20 collides with the cabinet 120 when the point M rotates along the arc trajectory.

[0062] Please refer to Figure 4. The angle α between the line connecting point Q2 and point M and the outer edge 23 is 40° to 50° (e.g., 40°, 42°, 45°, 48°, 50°, etc.).

[0063] For example, the distance between point Q1 and the outer edge 23 is 6mm to 12mm (e.g., 6mm, 7mm, 9mm, 11mm, 12mm, etc.), and the distance between point Q1 and the first side edge 22 is 13mm to 19mm (e.g., 13mm, 14mm, 16mm, 18mm, 19mm, etc.).

[0064] For example, the distance between point O1 and the outer edge 23 is 6mm to 12mm (e.g., 6mm, 7mm, 9mm, 11mm, 12mm, etc.), and the distance between point O1 and the first edge is 24mm to 30mm (e.g., 24mm, 25mm, 27mm, 29mm, 30mm, etc.).

[0065] In some embodiments, the angle between the line connecting point Q2 and point M and the outer edge 23 is 45°.

[0066] In some embodiments, the distance between point Q1 and the outer edge 23 is 9 mm, and the distance between point Q1 and the first side edge 22 is 16 mm.

[0067] In some embodiments, the distance between point O1 and the outer edge 23 is 9 mm, and the distance between point O1 and the first side edge 22 is 27 mm.

[0068] Please refer to Figure 3. The second shaft 32 includes a third part 323 and a fourth part 324 connected in sequence. The end of the fourth part 324 away from the third part 323 is a free end. Both the third part 323 and the fourth part 324 are cylinders. The center of the cross-section of the third part 323 corresponds to the center of the cross-section of the fourth part 324. Furthermore, the diameter of the fourth part 324 is smaller than the diameter of the third part 323.

[0069] It is understood that the axis of the second shaft 32 is the straight line containing the center of the cross-section of the third part 323 and the center of the cross-section of the third part 323.

[0070] For example, in the second shaft 32, the ratio of the length of the fourth part 324 to the length of the third part 323 is (1~3):(1~3), such as 1:1, 1:2, 1:3, 3:1, 2:1, 3:2, 2:3, etc.

[0071] For example, in the second shaft 32, the ratio of the diameter of the fourth part 324 to the diameter of the third part 323 is 1:(1 to 5), such as 1:1, 1:2, 1:3, 1:4, 1:5, etc.

[0072] Please refer to Figure 5. The second slide groove 26 includes a first groove 261 and a second groove 262 that are interconnected. The first groove 261 and the second groove 262 are arranged sequentially in the depth direction of the second slide groove 26. The bottom of the second groove 262 forms the bottom of the second slide groove 26. The side of the first groove 261 facing away from the second groove 262 forms the opening of the second slide groove 26. The width of the second groove 262 is smaller than the width of the first groove 261. The fourth part 324 of the second shaft 32 is inserted into the second groove 262, and the third part 323 of the second shaft 32 is inserted into the first groove 261.

[0073] Referring to Figure 4, it can be understood that because the directions of the Q1-Q2 and Q2-Q3 trajectory segments are different, the second slide groove 26 has a large gap at the intersection of the Q1-Q2 and Q2-Q3 trajectory segments (i.e., the area around point Q2). Therefore, when the second shaft 32 moves to point Q2, it is easy for it to move within the wider gap. Therefore, in this embodiment, the lower half of the second slide groove 26 (i.e., the second groove 262) is set to a smaller width. Correspondingly, the second shaft 32 is inserted... The portion of the second groove 262 (the fourth portion 324) is configured to have a smaller diameter. Since the area of ​​the gap at the junction of the Q1-Q2 track segment and the Q2-Q3 track segment on the second groove 262 is smaller, the movement of the third portion 323 of the second shaft 32 can be reduced, thereby reducing the overall movement of the second shaft 32. This results in a higher smoothness when the second shaft 32 moves from the Q1-Q2 track segment to the Q2-Q3 track segment within the second slide groove 26, thereby improving the smoothness of the rotation of the door 20.

[0074] Please refer to Figure 3. The first shaft 31 includes a first part 311 and a second part 312 connected in sequence. The end of the second part 312 away from the first part 311 is a free end. The first part 311 is a cylinder and the second part 312 is a semi-cylinder. The center of the cross-section of the second part 312 corresponds to the center of the cross-section of the first part 311.

[0075] It is understood that the axis of the first shaft 31 is the straight line containing the center of the cross-section of the first part 311 and the center of the cross-section of the second part 312.

[0076] For example, in the first shaft 31, the ratio of the length of the first part 311 to the length of the second part 312 is (1~3):(1~3), such as 1:1, 1:2, 1:3, 3:1, 2:1, 3:2, 2:3, etc.

[0077] For example, the width of the second groove 26 is uniform in the depth direction.

[0078] In their experiments, the inventors of this application discovered that when the first shaft 31 is a uniformly shaped cylinder, during the rotation of the door 20, when the first shaft 31 moves to point O3 and the second shaft 32 moves to point Q2, the first shaft 31 can normally continue moving from point O3 to point O4. However, during this process, the second shaft 32 remains stationary at point Q2, thus failing to complete the door opening process normally. By designing the second part 312 of the first shaft 31 as an irregular shaft (semi-cylinder), the inventors of this application can use this irregular shaft to change the direction of the force between the groove wall of the first slide 25 and the first shaft 31. This allows the second shaft 32 to smoothly move from point Q2 to point Q3 during the process of the first shaft 31 moving from point O3 to point O4, thereby enabling the door 20 to open according to the expected motion trajectory.

[0079] Please refer to Figures 6 to 9. This application provides an embedded refrigerator device 100, including a cabinet 120 and a refrigerator 110. The cabinet 120 has an inner cavity, and the refrigerator 110 is accommodated in the inner cavity of the cabinet 120. The refrigerator 110 is the refrigerator 110 in any of the above embodiments.

[0080] Please refer to Figures 6 to 9. The cabinet 120 has an inner wall surface 121 located near the hinge 30. The distance L between the outer side surface 102 of the refrigerator 110 body 10 and the inner wall surface 121 of the cabinet 120 is 1mm-2mm (e.g., 1mm, 1.2mm, 1.5mm, 1.7mm, 2mm, etc.). As the door opening angle increases from zero to the maximum opening angle, the distance between point M on the door 20 and the inner wall surface 121 of the cabinet 120 is always greater than zero.

[0081] For example, the distance between the first side 22 of the first end face 101 of the door 20 of the refrigerator 110 and the inner wall 121 of the cabinet 120 is equal to the distance L between the outer side 102 of the cabinet 10 of the refrigerator 110 and the inner wall 121 of the cabinet 120.

[0082] Please refer to Figure 9. The inner wall surface 121 and the front end surface 122 of the cabinet 120 intersect at the side edge. The point on the side edge corresponding to the second end surface 201 of the door 20 is point N. When the opening angle of the door 20 is 120°, the distance between the rotation center (point O0) of the door 20 and point N is greater than 0 and less than or equal to 6 mm (e.g., 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, etc.) to avoid the door 20 colliding with the side edge of the cabinet 120 during rotation.
