Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, in particular to refrigeration equipment. Background Art

[0002] Embedded electrical appliances can be integrated with the external environment and are becoming more and more popular. Embedded refrigeration equipment, such as embedded refrigerators, generally includes a box body and a door body that rotates on the box body. A storage space is provided in the box body, and the door body is used to open or close the storage space. In order to make the door body more beautiful after closing, the distance between the embedded refrigeration equipment and the external environment is made as small as possible after the door body is closed, but such a structural setting will affect the opening of the door body. In order to solve the above technical problems, a hinge assembly with a dual-axis structure is used in the prior art, that is, while the door body rotates along the main axis during opening, there is also a secondary axis to guide the door body to control the movement of the door body, so that the movement of the door body can be controlled during the opening process to avoid interference from external environmental parts.

[0003] The hinge components in the prior art are mostly biaxial, with a relatively complex structure and complicated motion trajectory, which is not convenient for practical application. Summary of the invention

[0004] The purpose of the present invention is to arrange a sliding part and a rotating part in the axial direction of the shaft so that the door body adopts different methods at different stages during the opening process, so that the door body can avoid interference from other components in the initial stage of opening while also being able to achieve a larger angle of opening.

[0005] To achieve one of the above-mentioned objects, the present invention provides a refrigeration device comprising a box body, a door body and a hinge assembly; the door body is pivoted on the box body through the hinge assembly;

[0006] The hinge assembly includes a hinge plate and a rotating shaft; the hinge plate is fixed on the box body and has a slide groove, the rotating shaft has a rotating part and a sliding part arranged along the axial direction, and the sliding part is slidably matched with the slide groove;

[0007] The door body is provided with a rotating hole matched with the rotating part and a protrusion located on the inner wall of the rotating hole, and the rotating part is located in the rotating hole and can rotate in the rotating hole;

[0008] The hinge assembly also has a rotation control member disposed on the rotating shaft, and the rotation control member has a locking state that abuts against the protrusion to limit the rotation of the rotating shaft;

[0009] Under the action of external force, the rotation control member can shrink, deform or move to break away from the abutment with the protrusion, and the rotating part can generate relative rotation in the rotating hole.

[0010] Furthermore, the door body has relatively arranged side walls and a front wall of the box, the slide groove is extended in a curve as a whole, and when the door body is closed, the slide groove extends in a direction gradually away from the side walls of the box and gradually away from the front wall of the box.

[0011] Furthermore, the slide groove has a first groove section and a second groove section which are arranged in sequence along the extension direction of the slide groove. When sliding along the first groove section, the distance away from the side wall of the box is greater than the distance away from the front wall of the box; when sliding along the second groove section, the distance away from the front wall of the box is greater than the distance away from the side wall of the box.

[0014] Furthermore, the reset mechanism includes a reset spring and a moving rod, one end of the moving rod is pivotally connected to the rotation control member, and the other end of the moving rod can slide along a moving direction perpendicular to the rotation control member;

[0015] Under the action of external force, the rotation control member moves toward the avoidance space, and the end of the moving rod away from the rotation control member slides in a direction away from the rotation control member, causing the return spring to accumulate resilience;

[0016] After the external force is removed, the moving rod is reset and moved under the action of the reset spring, and drives the rotating control member to move in a direction protruding out of the avoidance space.

[0017] Furthermore, the reset mechanism also has a sliding rod, which is slidably arranged along a moving direction perpendicular to the rotating control member, and the other end of the moving rod is pivotally connected to the sliding rod; the reset spring cooperates with the sliding rod.

[0018] Furthermore, the sliding rod is slidably arranged along the axial direction of the rotating shaft, and the return spring is a compression spring having a first end fixed to the bottom of the rotating hole and a second end fixed to the sliding rod;

[0019] When the rotary control member moves toward the avoidance hole, the rotating shaft moves upward along the axial direction and compresses the compression spring.

[0020] Furthermore, the sliding rod protrudes downward from the bottom of the rotating shaft in the axial direction, and a rotating support plate adapted to the sliding rod is provided on the hinge plate. The rotating support plate is provided on the side of the hinge plate away from the sliding part, and the rotating support plate is provided parallel to the hinge plate and opposite to the sliding groove.

[0023] Furthermore, a sliding part rotation limiting surface is provided on the sliding part, and the sliding part rotation limiting surface is used to abut against the inner wall of the slide groove to limit the sliding part from rotating in the slide groove;

[0024] The rotating shaft also has an upper limit plate and a lower limit plate, the sliding portion is arranged between the upper limit plate and the lower limit plate, and the upper limit plate and the lower limit plate are arranged on opposite sides of the hinge plate.

[0044] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0045] One embodiment of the present invention provides a refrigeration device, which can be a box embedded in an external environment part. The external environment part can be, for example, a decorative part such as a cabinet or a stone slab. The refrigeration device can be a refrigerator or other household appliances embedded in the external environment part, such as a wine cabinet, a storage cabinet, etc.

[0046] In this embodiment, Figure 1 As shown, the refrigeration device includes a box body 1 for providing an internal storage space, a door body 2 and a hinge assembly 3, and the door body 2 is pivoted on the box body 1 through the hinge assembly 3 to open or close the storage space;

[0047] In this embodiment, the box body 1 has a box front wall 11 and a box side wall 12 arranged perpendicular to the box front wall 11. In this embodiment, the box front wall 11 and the box side wall 12 are roughly flat. The opening of the storage space is arranged on the box front wall 11, and the door body 2 is located at the front side of the box body 1 as a whole, and when the door body 2 is in a closed state, the opening of the storage space is closed. It should be noted that the front side here is the opening direction of the storage space.

[0048] The door body 2 also has a door front wall 21, a door side wall 22 and a door rear wall. The intersection of the door front wall 21 and the door side wall 22 forms a door outer edge 23, and the intersection of the door side wall 22 and the door rear wall forms a door inner edge 24. When the door body 2 is in a closed state, that is, when the door body 2 covers the storage space opening, the door front wall 21 is arranged on the side of the door body 2 away from the box front wall 11. In this embodiment, the door front wall 21 is flat as a whole, and is roughly parallel to the box front wall 11 when the door body 2 is in a closed state.

[0049] The box body 1 is arranged beside the external environment part. After the box body 1 is put in place, the box side wall 12 faces the first side of the external environment part, that is, the box side wall 12 is opposite to the first side of the external environment part, and the box side wall 12 is roughly parallel to the first side of the external environment part.

[0050] When the door body 2 is in the closed state, the door side wall 22 also faces the first side of the external environment component, and the door side wall 22 is opposite to the first side. In this embodiment, the door side wall 22 is flat as a whole, and is roughly parallel to the first side of the external environment component.

[0051] In this embodiment, the door front wall 21 and the door side wall 22 are both roughly planar. When the door body 2 is in a closed state, the door front wall 21 is parallel to the box front wall 11, and the plane where the door side wall 22 is located is parallel to the plane where the box side wall 12 is located. Of course, in other embodiments, the door front wall 21 and the door side wall 22 can also be curved or cambered.

[0052] In this specific embodiment, Figure 1-9 As shown, the hinge assembly 3 includes a hinge plate 31 and a rotating shaft 32; the hinge plate 31 is fixed on the box body 1 and has a slide groove 310.

[0053] The rotating shaft 32 is in the shape of a long column and is extended along its axial direction. The rotating shaft 32 has a rotating portion 321 and a sliding portion 322 arranged along the axial direction. The sliding portion 322 is slidably matched with the sliding groove 310.

[0054] like Figure 11-12 As shown, the door body 2 is provided with a rotating hole 25 adapted to the rotating portion 321 and a protrusion 26 located on the inner wall of the rotating hole 25, and the rotating portion 321 is located in the rotating hole 25 and can rotate in the rotating hole 25;

[0055] like Figure 5-9 As shown, the hinge assembly 3 further comprises a rotation control member 33 disposed on the rotating shaft 32, and the rotation control member 33 has a locking state that abuts against the protrusion 26 to limit the rotation of the rotating shaft 32;

[0056] Under the action of external force, the rotation control member 33 may shrink, deform or move to break away from the contact with the protrusion 26 , and the rotation portion 321 may generate relative rotation in the rotation hole 25 .

[0057] In this embodiment, the rotation control member 33 moves after being acted upon by an external force to get rid of the contact with the protrusion 26 . After the rotation control member 33 and the protrusion 26 are no longer constrained on the rotation portion 321 , the rotation portion 321 can rotate in the rotation hole 25 .

[0058] In other embodiments, the rotation control member 33 may also generate elastic deformation and shrinkage after an external force acts to get rid of the restriction of the protrusion 26 .

[0059] In the initial stage of opening the door body 2, the sliding part 322 slides along the sliding groove 310. After sliding to the end of the sliding groove 310, as the force of pulling the door body 2 further increases, the force of pulling the door body 2 is transmitted to the rotating control member 33, forming an external force that drives the rotating control member 33 to move.

[0060] The rotation control member 33 contracts and deforms or moves after being acted upon by an external force, so as to release the locking state in which the rotation control member 33 abuts against the protrusion 26. In the locked state, the rotation control member 33 abuts against the protrusion 26, thereby restricting the rotation of the rotation part 321 in the rotation hole 25. After the rotation control member 33 is freed from the restriction of the protrusion 26, the rotation part 321 can rotate in the rotation hole 25.

[0061] In this embodiment, by providing a sliding portion 322 and a rotating portion 321 in the axial direction of the rotating shaft 32, the door body 2 adopts different methods at different stages during the opening process. The rotating shaft of the door body 2 first slides and then rotates in situ, so that the door body 2 can better avoid interference from other components in the initial stage of opening. After the door body 2 is opened to a certain angle, the rotating shaft 32 can rotate through the rotating portion 321 to achieve a larger angle of opening of the door body.

[0062] In the initial stage of opening the door body 2, in order to avoid interference between the inner edge 24 of the door and the box body 1, and also to avoid interference between the outer edge 23 of the door and the external environment, the door body 2 moves in a direction away from the box body 1 and the external environment at the same time, that is, the door body 2 moves in a direction away from the front wall 11 and the side wall 12 of the box at the same time.

[0063] In this embodiment, if Figure 1-3 As shown, since the slide slot 310 is arranged on the box body, the sliding portion 322 of the rotating shaft 32 is arranged on the door body. The slide slot 310 is arranged to extend in a curve as a whole, and when the door body 2 is closed, the slide slot 310 extends in a direction gradually away from the box side wall 12 and gradually away from the box front wall 11.

[0064] It should be noted that the extension direction of the slide groove 310 refers to the moving direction of the rotating shaft 32 from the initial position to the terminal position when the door body 2 is in the process of being closed and opened.

[0065] The slide groove 310 has a first groove section and a second groove section which are arranged in sequence along the extension direction of the slide groove 310. When sliding along the first groove section, the distance away from the box side wall 12 is greater than the distance away from the box front wall 11; when sliding along the second groove section, the distance away from the box front wall 11 is greater than the distance away from the box side wall 12.

[0066] During the opening process of the door body 2, as the opening angle of the door body 2 increases, the sliding part 322 slides along the first slot section and the second slot section in sequence. It should be noted that there is no clear boundary between the first slot section and the second slot section, and this only indicates the sliding process of the sliding part 322 in the slide slot 310.

[0067] When sliding along the first groove section, the movement range of the sliding part 322 relatively away from the box side wall 12 is greater than the movement range of the sliding part 322 relatively away from the box front wall 11, that is, when moving in the first groove section, compared with the direction away from the box body 1, the door body 2 is more inclined to move away from the box side wall 12, that is, the door body 2 is more inclined to move away from the external environment. This means that compared with moving forward, the door body 2 is more inclined to move inward.

[0068] When sliding along the second groove section, the movement range of the sliding part 322 away from the box front wall 11 is relatively greater than the movement range of the sliding part 322 away from the box side wall 12, that is, when moving in the second groove section, the door body 2 is more inclined to move away from the box front wall 12 than to move away from the box side wall 12. That is, compared with moving inward, the door body 2 is more inclined to move forward.

[0069] Before the door body 2 opens to the first angle, when the sliding part 322 slides relatively along the first groove section, the distance that the door body 2 moves forward relative to is smaller than the distance that it moves inward; when the door body 2 opens from the first angle to the second angle, the sliding part 322 slides along the second groove section, and at this time, the distance that the door body 2 moves inward is smaller than the distance that it moves forward, wherein the second angle is larger than the first angle.

[0070] The above structure allows the slide groove 310 to extend in an arc shape as a whole, and the overall shape of the slide groove 310 is arched away from the door outer edge 23, and the slide groove 310 is extended in a direction gradually away from the box side wall 12 and the box front wall 11.

[0071] In the embodiment where the sliding portion 322 of the rotating shaft 32 is arranged on the door body 2 and the sliding groove 310 is arranged on the box body 1, in the initial stage of the door body 2 being opened, the distance between the outer edge 23 of the door and the rotating shaft 32 is farther than the distance between the inner edge 24 of the door and the rotating shaft 32. Therefore, in the initial stage of the door body being opened, the movement amplitude of the outer edge 23 of the door is larger than the movement amplitude of the inner edge 24 of the door, which means that the outer edge 23 of the door is more susceptible to interference from external environmental components than the inner edge 24 of the door.

[0072] Therefore, when the first groove section moves, compared with the door body 2 moving away from the front wall 11 of the box, the door body 2 is more inclined to move inward, that is, it is more inclined to move away from the side wall 12 of the box, that is, the door body 2 is more inclined to move away from the external environment to avoid the door outer edge 23 being affected by interference from the external environment.

[0073] When the second slot section moves, compared with the door body 2 moving away from the box side wall 12, the door body 2 is more inclined to move in the front side, that is, it is more inclined to move in the direction away from the box front wall 12, that is, the door body 2 is more inclined to move in the direction away from the box body 1, so as to avoid the inner edge 24 of the door being affected by the interference of external environmental parts. The above-mentioned structure can be set to more finely control the opening process of the door body 2 according to the actual needs of the door body 2 during the opening process, and can better avoid the door body 2 from being interfered with during the opening process.

[0074] like Figure 5-10 As shown, the hinge assembly 3 also has a reset mechanism 4; an escape space 3210 is provided in the rotating portion 321, and under the action of an external force, the rotating control member 33 moves toward the escape space 3210;

[0075] After the external force is removed, the reset mechanism drives the rotation control member 33 to reset and move toward the outside of the avoidance space 3210 .

[0076] The reset mechanism can better realize the reset of the rotary control member 33 when the door body 2 is closed, so that it can be used again when the door is opened next time.

[0077] In a specific embodiment, the reset mechanism includes a reset spring 341 and a moving rod 342, one end of the moving rod 342 is pivotally connected to the rotation control member 33, and the other end of the moving rod 342 can slide along a moving direction perpendicular to the rotation control member 33; the other end of the moving rod 342 can be linked with the rotation control member 22, and the moving direction of the moving rod 342 is perpendicular to the moving direction of the rotation control member 33.

[0078] Under the action of external force, the rotation control member 33 moves toward the avoidance space 3210, and the end of the moving rod 342 away from the rotation control member 33 slides in a direction away from the rotation control member 33, causing the return spring 341 to accumulate resilience.

[0079] After the external force is removed, the moving rod 342 is reset under the action of the reset spring 341 and drives the rotating control member 33 to move in the direction of protruding out of the avoidance space 3210 .

[0080] It should be noted that under the action of external force, the rotating control member 33 only produces a tendency to move toward the avoidance space 3210 and does not need to be completely contained in the avoidance space 3210. The avoidance space 3210 is arranged in the rotating part 321 and has an opening arranged on the outer wall of the rotating part 321, and the rotating control member 33 protrudes outward from the opening.

[0081] In other embodiments, the rotation control member 33 may be directly disposed on the outer wall of the rotating portion 321 . In this case, the rotation control member 33 may be configured as an elastically deformable member.

[0082] In order to better realize the sliding of the moving rod 342 away from one end of the rotating control member 33, the reset mechanism 34 also has a sliding rod 343, which is slidably arranged along a moving direction perpendicular to the rotating control member 33, and the other end of the moving rod 342 is pivotally connected to the sliding rod 343; the reset spring 341 cooperates with the sliding rod 343.

[0083] In this embodiment, the rotation control member 33 controls the movement of the sliding rod 343, and the rotation control member 33 is linked with the rotation control member 33. In other embodiments, the sliding rod 343 can also be controlled to move by an independent control mechanism.

[0084] In this embodiment, the sliding rod 343 is slidably arranged along the axial direction of the rotating shaft 32, and the return spring 341 is a compression spring having a first end fixed to the bottom of the rotating hole 25 and a second end fixed to the sliding rod 343;

[0085] When the rotation control member 33 moves toward the avoidance hole 3210 , the rotating shaft 32 moves upward along the axial direction and compresses the compression spring.

[0086] The sliding rod 343 protrudes downward from the bottom of the rotating shaft 32 in the axial direction, and a rotating support plate 311 adapted to the sliding rod 343 is provided on the hinge plate 31. The rotating support plate 311 is arranged on the side of the hinge plate 31 away from the sliding portion 322. The rotating support plate 311 is arranged parallel to the hinge plate 31 and opposite to the sliding groove 310.

[0087] In this embodiment, if Figure 5 and 10 As shown, the sliding rod 343 can move along the axial direction of the rotating shaft 32. The sliding rod 343 is arranged to move along the axial direction, so that after the external force is removed, the sliding rod 343 can be reset downward under the action of its own gravity, thereby better realizing the reset of the sliding rod 343. Under the combined action of the gravity of the sliding rod 343 and the reset spring 341, the rotation control member 33 extends outward from the avoidance space 3210 and presses against the protrusion 26.

[0088] The sliding rod 343 moves upward, thereby forming an escape for the movement of the rotation control member 33 into the escape space 3210, so as to facilitate the rotation of the rotating portion 321 in the rotating hole 25. In this embodiment, the bottom of the sliding rod 343 protrudes downward from the bottom of the sliding portion 322 and is pressed against the rotating support plate 311, so that the rotating shaft 32 can be stably supported during the rotation process.

[0089] In other embodiments, the resetting movement of the rotating control member 33 can be controlled only by the resetting member. Specifically, the resetting member can be set in the rotating control member 33 and the avoidance space 3210, and the resetting member can be telescopically deformed along the moving direction of the rotating control member 33.

[0090] In a specific embodiment, Figure 7 and 12 As shown, the protrusion 26 has a rotation limit surface 261 and a guide surface 262 arranged opposite to each other, and the rotation control member 33 has a rotation abutment surface 331 and a reset guide surface 332 arranged opposite to each other; the rotation abutment surface 331 abuts against the rotation limit surface 261 to limit the rotation of the rotation control member 33 in the rotation hole 25; the reset guide surface 332 can be reset and moved along the guide surface 262.

[0091] During the opening of the door 2, Figure 7 As shown, in the initial stage, the rotation abutting surface 331 abuts against the rotation limiting surface 261 to limit the rotation of the rotation part 321 in the rotation hole 25. At this time, the rotating shaft 32 can only make the sliding part 322 slide along the slide groove 310 of the door body 2. When sliding along the slide groove 310 to the end of the slide groove 310, as the door body 2 is further opened, the force acting on the rotation control member 33 increases to overcome the force of the reset mechanism 34, and the rotation control member 33 moves inward and moves toward the avoidance space 3210. The rotation control member 33 can cross the protrusion 26 and move from the rotation limiting surface 261 to the guide surface 262. The rotation control member 33 is free from the limitation of the protrusion 26 and can rotate in the rotation hole 25, thereby increasing the opening angle of the door body 2.

[0092] When the door body 2 is closed, the return guide surface 332 of the rotation control member 33 passes over the protrusion 26 along the guide surface 262 , so that the rotation control member 33 moves to the rotation abutment surface 331 and abuts against the rotation limit surface 261 .

[0093] In this embodiment, the rotation limiting surface 261 and the guide surface 262 form the inner wall of the rotation hole 25, and the inner wall of the rotation hole 25 also has a curved surface 251. The rotating portion 321 has a pair of rotating shaft curved surfaces 3211 arranged opposite to each other, and the arc length of the curved surface 251 is greater than the arc length of the rotating shaft curved surface 3211.

[0094] The arc surface 3211 of the rotating shaft is opposite to the arc surface 251 , and the arc length of the arc surface 3102 is greater than the arc length of the arc surface 3211 of the rotating shaft, so that the rotating shaft 32 has a larger rotation space in the rotating hole 25 , thereby better realizing the rotation of the rotating shaft 32 .

[0095] It should be noted that, in order to better control the rotation of the rotating portion 321 , a pair of protrusions 26 are provided on the inner wall of the rotating hole 25 , and the pair of protrusions 26 are centrally symmetrically arranged with the rotating hole 25 as the center.

[0096] Correspondingly, two rotation control members 33 are also provided, and a pair of the rotation control members 33 are centrally symmetrically arranged with the sliding rod 343 as the center.
