Description

Technical Field

[0001] The present invention relates to the field of refrigeration devices, and in particular to a refrigerator. Background Art

[0002] With the development of society and the gradual improvement of living standards, people's demand for aesthetically pleasing refrigerators has become increasingly prominent. Embedding refrigerators into cabinets, or built-in refrigerators, has become a popular home decoration method to achieve a unified decoration style.

[0003] Currently, refrigerators all use hinges to pivotally connect doors to the refrigerator body, allowing them to be opened and closed by rotating the door. For built-in refrigerators, the door must be opened and closed to avoid interference with the cabinets, refrigerator body, etc. Therefore, the hinges must be designed to adjust the door's motion trajectory to avoid interference between the door and the cabinet.

[0004] Existing built-in refrigerators generally adjust the movement trajectory of the door body by using a multi-link hinge. However, the multi-link hinge has a complex structure, a large volume, and cannot accurately control the movement trajectory of the door body.

[0005] In view of this, it is necessary to provide a new refrigerator to solve the above problems. Summary of the Invention

[0006] An object of the present invention is to provide a refrigerator.

[0007] To achieve the above-mentioned object, the present invention adopts the following technical solution: a refrigerator, comprising a cabinet, a hinge plate fixed to the cabinet, and a door body rotatably connected to the hinge plate, wherein one of the hinge plate and the door body is provided with a hinge shaft, and the other is provided with a long axis hole that cooperates with the hinge shaft, the long axis hole having a first end and a second end opposite to each other, and when the door body is in a closed state, the hinge shaft is located at the first end; the refrigerator further comprises:

[0008] a magnetic drive assembly, arranged on the same side as the long axis hole, the magnetic drive assembly acting on the hinge shaft to drive the hinge shaft and the long axis hole to move relative to each other, so as to translate the door body;

[0009] a stop rib, arranged on the same side as the hinge shaft, the stop rib being in an arc shape and arranged concentrically with the hinge shaft;

[0010] A positioning groove is arranged on the same side of the long axis hole and cooperates with the stop rib. The positioning groove has a first groove section, a second groove section, and a transition groove section connecting the first groove section and the second groove section. The transition groove section has a guide wall connecting the first groove section and the second groove section. When the door body is in a closed state, the stop rib is located in the first groove section. When the door body is opened and the hinge shaft moves toward the second end relative to the long axis hole, the stop rib moves along the guide wall through the transition groove section to the second groove section. After the hinge shaft is located at the second end, the stop rib is located in the second groove section.

[0011] As a further improved technical solution of the present invention, the magnetic drive assembly includes an electromagnet fixedly arranged relative to the long axis hole, a magnetic core movably connected to the electromagnet, and a limit plate connected to the magnetic core, and the hinge shaft is connected to the limit plate; when the electromagnet is in an energized state, the magnetic core moves relative to the electromagnet, driving the hinge shaft to move toward the second end relative to the long axis hole.

[0012] As a further improved technical solution of the present invention, the electromagnet has a guide groove matching the magnetic core, and the magnetic core is movably connected in the guide groove.

[0013] As a further improved technical solution of the present invention, the magnetic drive component also includes an elastic member arranged in the guide groove, and the magnetic core is connected to the elastic member; when the electromagnet is in a power-off state, the elastic member limits the movement of the hinge shaft located at the first end along the long axis hole and is used to drive the hinge shaft located at the second end to move relative to the long axis hole toward the first end and reset.

[0014] As a further improved technical solution of the present invention, the long axis hole is arranged on the door body; the door body has an installation cavity connected to the side of the long axis hole away from the hinge plate, and the magnetic drive component is installed in the installation cavity and connected to the hinge shaft.

[0015] As a further improved technical solution of the present invention, when the door body opens from a closed state to a first preset angle, the hinge shaft remains at the first end, and the stop rib moves to the junction section of the first groove section and the transition groove section.

[0016] As a further improved technical solution of the present invention, the positioning groove also includes a third groove section arranged from the end of the second groove section away from the first groove section and connected to the second groove section. When the hinge shaft is reset from the second end to the first end, the stop rib moves from the second groove section to the third groove section.

[0017] As a further improved technical solution of the present invention, one of the hinge plate and the door body has a limiting wall, and the other is provided with a limiting shaft that cooperates with the limiting wall; the limiting wall includes a starting end, an end terminal, and a first limiting wall located between the starting end and the end terminal. When the door body is in a closed state, the limiting shaft is located at the starting end. When the hinge shaft is reset from the second end to the first end relative to the long axis hole, the limiting shaft is held against the first limiting wall and moves along the first limiting wall toward the end terminal.

[0018] As a further improved technical solution of the present invention, the limiting wall also includes a second limiting wall located between the first limiting wall and the starting end. When the door body is opened until the hinge shaft moves from the first end to the second end relative to the long axis hole, the limiting shaft is supported by the second limiting wall and moves along the second limiting wall toward the direction of the terminal.

[0019] As a further improved technical solution of the present invention, the limiting wall also includes a third limiting wall extending from the starting end to the first limiting wall. When the door body rotates from the closed state to the first preset opening angle, the hinge shaft remains at the first end, and the limiting shaft is supported by the third limiting wall and moves along the third limiting wall in the direction away from the starting end.

[0020] As a further improved technical solution of the present invention, the hinge plate or door body on which the limiting wall is provided is provided with a limiting groove that matches the limiting shaft, and the groove wall of the limiting groove serves as the limiting wall.

[0021] As a further improved technical solution of the present invention, the long axis hole is arranged on the door body, the long axis hole extends along the thickness direction of the door body, and the second end is located on the side of the first end away from the front wall of the door body.

[0022] The beneficial effects of the present invention are as follows: the refrigerator of the present invention drives the hinge shaft and the long axis hole to move relative to each other by setting a magnetic drive component, so as to drive the door body to move horizontally. At the same time, a stop rib and a positioning groove are set to limit the relative movement speed between the hinge shaft and the long axis hole, so that the door body can move according to a preset trajectory. At the same time, it can prevent the hinge shaft and the long axis hole from colliding and reduce noise. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. Figures 1-6 Detailed description of the preferred embodiments of the present invention is provided below. Throughout the description, identical or similar reference numerals denote identical or similar elements or elements having identical or similar functions. It should be noted, however, that these embodiments are not intended to limit the present invention. Any equivalent functional, methodological, or structural modifications or substitutions made by persons skilled in the art based on these embodiments fall within the scope of protection of the present invention.

[0030] Please refer to Figure 1 As shown, the present invention provides a refrigerator, comprising a refrigerator body 1, a hinge plate 2 fixed to the refrigerator body 1, and a door body 3 rotatably connected to the hinge plate 2. One of the hinge plate 2 and the door body 3 is provided with a hinge shaft 21, and the other is provided with a long axis hole 31 that cooperates with the hinge shaft 21. The door body 3 is rotatably connected to the hinge plate 2 through the cooperation between the hinge shaft 21 and the long axis hole 31.

[0031] Combine Figure 3 As shown, the door body 3 includes a front wall 32, a hinge mounting side 33, and a pivot end 34. In the present invention, the refrigerator is a built-in refrigerator as an example for specific explanation. The front wall 32 of the door body 3 is the side of the refrigerator facing the external environment when it is embedded in the cabinet 4. The hinge mounting side 33 of the door body 3 is the upper side of the door body 3, that is, one end of the hinge plate 2 is mounted on the hinge mounting side 33, and the other end of the hinge plate 2 is mounted on the box body 1. The pivot end 34 of the door body 3 is the end of the door body 3 that rotates around the box body 1.

[0032] Among them, only the cabinet 4 on one side of the pivot end 34 is shown. In actual installation, the refrigerator is completely embedded in the cabinet 4. It is understandable that the refrigerator is not necessarily embedded in the cabinet 4, but can also be embedded in the wall, or the refrigerator is a non-embedded refrigerator.

[0033] A direction from the center of the door body 3 in the closed state toward the pivot end 34 of the door body 3 is defined as a first direction, and a direction opposite to the first direction is defined as a second direction.

[0034] Specifically, when the hinge plate 2 is provided on the right side of the refrigerator, the first direction is from left to right, and the second direction is from right to left. When the hinge plate 2 is provided on the left side of the refrigerator, the first direction is from right to left, and the second direction is from left to right.

[0035] Specifically, the long axis hole 31 has a first end 311 and a second end 312 opposite to each other. When the door body 3 is in the closed state, the hinge shaft 21 is located at the first end 311. That is, during the process of opening and closing the door body 3, the hinge shaft 21 switches between the first end 311 and the second end 312 relative to the long axis hole 31, enabling the door body 3 to translate in a predetermined direction and move along a predetermined trajectory.

[0036] The following is a specific explanation using the example of the hinge shaft 21 being provided on the hinge plate 2 and the long axis hole 31 being provided on the door body 3. It is understood that during the process of opening and closing the door body 3, the hinge shaft 21 remains in position, while the long axis hole 31 moves with the movement of the door body 3. Thus, the long axis hole 31 moves relative to the hinge shaft 21, allowing the hinge shaft 21 to switch between the first end 311 and the second end 312. Of course, this is not limiting, and in other embodiments, the hinge shaft 21 may also be provided on the door body 3, in which case the long axis hole 31 is provided on the hinge plate 2.

[0037] Furthermore, the refrigerator further includes a magnetic drive assembly 5 disposed on the same side as the long axis hole 31. The magnetic drive assembly 5 acts on the hinge shaft 21 to drive the hinge shaft 21 and the long axis hole 31 to move relative to each other, thereby causing the door body 3 to translate. In the present invention, by providing the magnetic drive assembly 5 to drive the translation of the door body 3, there is no need to change the structure of the hinge plate 2. The structure is simple and easy to implement. The movement trajectory of the door body 3 during the opening and closing process can be controlled according to specific needs, making the refrigerator suitable for multiple scenarios, such as embedded scenarios.

[0038] It can be understood that the above-mentioned setting on the same side as the long axis hole 31 means that the long axis hole 31 and the magnetic drive component 5 are set on the door body 3 at the same time, or are set on the hinge plate 2 at the same time, so that the magnetic drive component 5 can act on the hinge shaft 21 to make the hinge shaft 21 and the long axis hole 31 move relative to each other.

[0039] In this embodiment, the long axis hole 31 is provided on the door body 3 , and the magnetic drive assembly 5 is provided on the door body 3 .

[0040] Specifically, combined Figure 4-Figure 5 As shown, the magnetic drive component 5 is configured to drive the hinge shaft 21 to move from the first end 311 to the second end 312 when the door body 3 continues to open from the first preset angle to the second preset angle.

[0041] In one specific embodiment, the long axis hole 31 extends along the thickness direction of the door body 3, and the second end 312 is located on the side of the first end 311 away from the front wall 32 of the door body 3, that is, the first end 311 is located in front of the second end 312. When the opening angle of the door body 3 is between 0° and 90°, the angle between the extension direction of the long axis hole 31 and the first direction gradually decreases. Therefore, when the opening angle of the door body 3 is between 0° and 90°, when the door body 3 translates to move the hinge shaft 21 from the first end 311 to the second end 312, the door body 3 moves toward the first direction and away from the box body 1 at the same time. On the one hand, by moving the door body 3 away from the cabinet 1 in the first direction, the door body 3 can be moved as far away from the cabinet 1 as possible in the first direction, thereby ensuring the opening degree of the door body 3 and preventing the door body 3 from blocking the storage compartment in the cabinet 1 or the drawer in the cabinet 1 from being interfered with by the door body 3 and unable to be opened, thereby facilitating the user to take out and put in items. On the other hand, by moving the door body 3 in the direction away from the cabinet 1, the distance between the door body 3 and the cabinet 1 is increased, thereby preventing the rear wall of the door body 3 from interfering with the cabinet 1 during the opening process of the door body 3. At the same time, for a built-in refrigerator, the front wall 32 of the door body 3 can be positioned at one end of the pivot end 34 and protrude forward from the front end of the cabinet 4, thereby reducing the interference between the door body 3 and the cabinet 4 during the rotation process of the door body 3. Of course, this is not limited to the above. It is understandable that the extension direction of the long axis hole 31 can be adjusted according to specific needs to control the translation direction of the door body 3.

[0042] In one embodiment, the second preset angle is 90°. Of course, this is not limiting. That is, during the process of the door 3 opening from the first preset angle to the second preset angle, the movement trajectory of the door 3 is such that the door 3 moves toward the first direction while simultaneously moving away from the box 1.

[0043] Specifically, the door body 3 has a mounting cavity in communication with the side of the long-axis hole 31 away from the hinge plate 2. The magnetic drive assembly 5 is mounted in the mounting cavity and connected to the hinge shaft 21 from the side of the long-axis hole 31 away from the hinge plate 2. This allows the magnetic drive assembly 5 to act on the hinge shaft 21, driving the hinge shaft 21 to move relative to the long-axis hole 31.

[0044] In one specific embodiment, the magnetic drive assembly 5 includes an electromagnet 51 fixedly disposed in the mounting cavity, a magnetic core 52 movably connected to the electromagnet 51, and a limit plate 53 connected to the magnetic core 52. The hinge shaft 21 is limitedly connected to the limit plate 53 so that the hinge shaft 21 and the limit plate 53 move synchronously. When the electromagnet 51 is energized, the electromagnet 51 and the magnetic core 52 are attracted to each other, and the magnetic core 52 and the electromagnet 51 move toward each other, driving the limit plate 53 and the electromagnet 51 to move toward each other. The limit plate 53 acts on the hinge shaft 21, causing the hinge shaft 21 to move toward the second end 312 relative to the long axis hole 31, thereby driving the door body 3 to translate simultaneously during the rotation process.

[0045] Furthermore, the electromagnet 51 has a guide groove 511 that cooperates with the magnetic core 52. The magnetic core 52 is movably connected in the guide groove 511, which can limit the direction of relative movement between the magnetic core 52 and the electromagnet 51, enhance the stability of the magnetic drive component 5, and enhance the stability of the translation of the door body 3.

[0046] Further, combined with Figure 3-Figure 4 as well as Figure 5-Figure 6 As shown, the magnetic drive assembly 5 is further configured such that: when the door body 3 opens from a closed state to a first preset angle, the magnetic drive assembly 5 maintains the hinge shaft 21 at the first end 311, causing the door body 3 to rotate in place by the first preset angle. As the door body 3 continues to open from a second preset angle to a third preset angle, the magnetic drive assembly 5 drives the hinge shaft 21 to return from the second end 312 to the first end 311 relative to the long axis hole 31, causing the door body 3 to move in the second direction, thereby further increasing the opening of the door body 3 until the door body 3 opens to the third preset angle, making it easier for users to access items. Of course, this is not a limitation.

[0047] It can be seen that when the door body 3 is in the closed state, the door seal on the door body 3 is tightly attached to the box body 1. Therefore, when the door body 3 is opened from the closed state, the door body 3 is first rotated in place by a first preset angle, which can first separate the door seal from the box body 1 to prevent the door seal from being deformed or damaged, thereby affecting the subsequent sealing performance of the door body 3. Correspondingly, in the final stage of closing the door, the door body 3 is rotated in place to close, which can also reduce the deformation of the door seal and facilitate the smooth closing of the door body 3.

[0048] Meanwhile, for refrigerators with a flip beam, when the door 3 is opened from a closed state, it first rotates in place, which enables the flip beam to flip and disengage from the guide structure on the cabinet 1, allowing the door 3 to continue to rotate and open. Correspondingly, in the final stage of closing the door, as the door 3 rotates in place to close, the flip beam can be guided by the guide structure on the cabinet 1 to flip to cover the gap between the left and right door bodies 3.

[0049] In a specific embodiment, the first preset angle is between 30° and 60°, but is not limited thereto.

[0050] In a specific embodiment, please refer to Figure 2 As shown, the magnetic drive assembly 5 further includes an elastic member 54 disposed within the guide slot 511, and the magnetic core 52 is connected to the elastic member 54. During the process of opening the door body 3 from the closed state to the first preset angle, the electromagnet 51 is in an off-state. At this time, the elastic force of the elastic member 54 constrains the hinge shaft 21 to the first end 311, causing the door body 3 to rotate in place. During the process of opening the door body 3 from the first preset angle to the second preset angle, the electromagnet 51 is in an energized state. The electromagnet 51 and the magnetic core 52 are attracted to each other, and the magnetic core 52 and the electromagnet 51 move relative to each other, compressing the elastic member 54. At this time, the elastic member 54 is in a compressed state. Consequently, during the process of opening the door body 3 from the second preset angle to the third preset angle, the electromagnet 51 is in an off-state. Under the elastic restoring force of the elastic member 54, the hinge shaft 21 returns from the second end 312 to the first end 311, causing the door body 3 to move in the second direction. Of course, this is not limited to the above. In other embodiments, the elastic member 54 may not be provided, and the movement trajectory of the door body 3 can be controlled by controlling the repulsion and attraction between the electromagnet 51 and the magnetic core 52, that is, the electromagnet 51 and the magnetic core 52 are controlled to repel each other to limit the hinge shaft 21 located at the first end 311 from moving along the long axis hole 31 and to drive the hinge shaft 21 located at the second end 312 to move toward the first end 311 relative to the long axis hole 31.

[0051] The elastic member 54 can be a spring, which has a simple structure and good stability. Of course, the present invention is not limited thereto.

[0052] For further information, see Figure 3-Figure 6 As shown, the refrigerator further includes a stop rib 22 disposed on the same side as the hinge shaft 21, and a positioning groove 35 disposed on the same side as the long axis hole 31 and cooperating with the stop rib 22. The positioning groove 35 limits the movement of the stop rib 22, thereby limiting the movement speed of the hinge shaft 21 relative to the long axis hole 31, allowing the hinge shaft 21 and the long axis hole 31 to move relatively slowly, thereby enhancing the stability of the movement of the door body 3, reducing collisions between the hinge shaft 21 and the long axis hole 31, preventing damage, and reducing noise.

[0053] Specifically, the stop rib 22 is in an arc shape and is arranged concentrically with the hinge shaft 21 , and the stop rib 22 and the hinge shaft 21 are spaced apart.

[0054] It is understood that the distance between the stop rib 22 and the hinge shaft 21 remains constant, and the position of the hinge shaft 21 can be restricted by restricting the position of the stop rib 22. Furthermore, the stop rib 22 is arc-shaped, so when the stop rib 22 is located in a groove section that matches its shape, the stop rib 22 will not shake, thereby restricting the shaking of the hinge shaft 21 and enhancing the stability of the movement of the door body 3.

[0055] Specifically, the positioning groove 35 has a first groove section 351, a second groove section 352, and a transition groove section 353 connecting the first groove section 351 and the second groove section 352. The distance between the stop rib 22 and the hinge shaft 21 is constant, so the distance between the first groove section 351 and the first end 311 is equal to the distance between the second groove section 352 and the second end 312, and the first groove section 351 is closer to the first end 311 than the second groove section 352.

[0056] When the door body 3 is in the closed state or is opened to a first preset angle from the closed state, the hinge shaft 21 is located at the first end 311, and the stop rib 22 is located in the first groove section 351 and moves to the intersection section between the first groove section 351 and the transition groove section 353. During the process of opening the door body 3 from the first preset angle to the second preset angle, the hinge shaft 21 moves toward the second end 312 relative to the long axis hole 31. At this time, the stop rib 22 moves from the intersection section through the transition groove section 353 to the second groove section 352. When the hinge shaft 21 is located at the second end 312, the stop rib 22 is located in the second groove section 352.

[0057] It can be understood that the junction section, transition groove section 353, and second groove section 352 are connected in the direction away from the long axis hole 31, and there is no obvious dividing line between adjacent sections, and there is an overlapping area so that the stop rib 22 can switch between the boundary section and the second groove section 352.

[0058] The transition groove section 353 has a guide wall connecting the first groove section 351 and the second groove section 352. The guide wall extends obliquely from one end of the first groove section 351 close to the second groove section 352, away from the long axis hole 31 and toward the direction where the second groove section 352 is located. When the door body 3 is opened to a first preset angle and the electromagnet 51 is energized to drive the hinge shaft 21 to move toward the second end 312 relative to the long axis hole 31, the stop rib 22 moves along the guide wall through the transition groove section 353 toward the second groove section 352. That is, the stop rib 22 abuts against the guide wall and moves along the guide wall, causing the hinge shaft 21 and the long axis hole 31 to move relatively slowly, thereby enhancing the stability of the movement of the door body 3 and reducing collisions between the hinge shaft 21 and the long axis hole 31, preventing damage and reducing noise.

[0059] Furthermore, the positioning groove 35 also includes a third groove section 354 which is connected to the second groove section 352 at one end of the second groove section 352 away from the first groove section 351. When the electromagnet 51 is in a power-off state and the elastic member 54 drives the hinge shaft 21 to reset from the second end 312 to the first end 311, the stop rib 22 moves from the second groove section 352 to the third groove section 354.

[0060] It is understandable that, under the action of the elastic restoring force of the elastic member 54, the end of the stop rib 22 near the third slot section 354 first contacts the side of the third slot section 354 near the long axis hole 31, and then the end of the stop rib 22 near the third slot section 354 abuts against the side of the third slot section 354 near the long axis hole 31 and gradually moves into the third slot section 354. This also allows the hinge shaft 21 and the long axis hole 31 to move relatively slowly, enhancing the stability of the door body 3 and reducing collision between the hinge shaft 21 and the long axis hole 31, thereby preventing damage and reducing noise.

[0061] Specifically, the third groove section 354 is an arc-shaped groove with the first end 311 as the center.

[0062] Further, combined with Figure 3-Figure 6As shown, one of the hinge plate 2 and the door body 3 is provided with a limiting wall, and the other is provided with a limiting shaft 23 that cooperates with the limiting wall. The cooperation between the limiting shaft 23 and the limiting wall further enables the hinge shaft 21 and the long axis hole 31, as well as the stop rib 22 and the positioning groove 35, to move relatively slowly, thereby enhancing the stability of the movement of the door body 3 and further reducing collisions between the hinge shaft 21 and the long axis hole 31, as well as between the stop rib 22 and the positioning groove 35, thereby preventing damage and reducing noise.

[0063] The limiting wall includes a starting end, a terminal end, and a first limiting wall 36 located between the starting end and the terminal end. When the door body 3 is closed, the limiting shaft 23 is located at the starting end. After the door body 3 is opened until the hinge shaft 21 is located at the second end 312 and the electromagnet 51 is de-energized, the elastic member 54 drives the hinge shaft 21 to return from the second end 312 to the first end 311. The limiting shaft 23 abuts against the first limiting wall 36 and moves along the first limiting wall 36 toward the terminal end. It can slow down the movement speed of the hinge shaft 21 toward the first end 311 and the movement speed of the stop rib 22 toward the third groove section 354, and prevent the hinge shaft 21 from moving quickly toward the first end 311 under the action of the elastic restoring force of the elastic member 54, and at the same time, the stop rib 22 from moving quickly toward the third groove section 354, causing the door body 3 to move unsteadily. In addition, it can prevent the hinge shaft 21 from colliding with the hole wall of the long axis hole 31 and the stop rib 22 from colliding with the groove wall of the positioning groove 35, causing damage, and reduce noise; at the same time, it can enable the door body 3 to move according to a preset trajectory, that is, in the process of the door body 3 opening from the second preset angle to the third preset angle, the door body 3 rotates and translates at the same time, and when the door body 3 opens to the third preset angle, the hinge shaft 21 moves to the first end 311 at the same time, and at the same time, the stop rib 22 is located in the third groove section 354.

[0064] Specifically, the first limiting wall 36 is arc-shaped, and the limiting shaft 23 abuts against the side of the first limiting wall 36 away from the long axis hole 31. Furthermore, along the direction from the starting end to the terminal end, the first limiting wall 36 gradually approaches the long axis hole 31. Therefore, when the limiting shaft 23 moves toward the terminal end along the first limiting wall 36, the hinge shaft 21 moves toward the first end 311.

[0065] Furthermore, the limiting wall further includes a second limiting wall 37 located between the first limiting wall 36 and the starting end. After the door body 3 is opened to a first predetermined angle, the electromagnet 51 is energized to drive the hinge shaft 21 from the first end 311 to the second end 312. At this time, the limiting shaft 23 abuts against the second limiting wall 37 and moves along the second limiting wall 37 toward the first limiting wall 36. It can further slow down the moving speed of the hinge shaft 21, and prevent the hinge shaft 21 from moving quickly toward the second end 312 under the action of the magnetic attraction force of the electromagnet 51, causing the door body 3 to move unsteadily; and it can make the door body 3 move according to a preset trajectory, that is, in the process of the door body 3 opening from the first preset angle to the second preset angle, the door body 3 rotates and translates at the same time, and when the door body 3 opens to the second preset angle, the hinge shaft 21 moves to the second end 312 at the same time; in addition, it can prevent the hinge shaft 21 from hitting the wall of the long axis hole 31, prevent damage and reduce noise.

[0066] Specifically, the second limiting wall 37 is arc-shaped, and the limiting shaft 23 abuts against the side of the second limiting wall 37 facing the long axis hole 31. Along the direction from the starting end to the terminal end, the second limiting wall 37 gradually moves away from the long axis hole 31. Therefore, when the limiting shaft 23 moves along the second limiting wall 37 toward the terminal end, the hinge shaft 21 moves toward the second end 3123.

[0067] Furthermore, the limiting wall also includes a third limiting wall 38 located between the starting end and the second limiting wall 37. When the door body 3 is opened from the closed state to the first preset angle, the hinge shaft 21 remains at the first end 311, and the limiting shaft 23 is supported on the third limiting wall 38 and moves along the third limiting wall 38 in the direction away from the starting end, so that the door body 3 rotates in place.

[0068] Specifically, the third limiting wall 38 is an arc centered at the first end 311. When the door body 3 is opened from a closed state to a first preset angle, the limiting shaft 23 moves along the third limiting wall 38 with the hinge shaft 21 as the center, confining the hinge shaft 21 to the first end 311. This prevents the hinge shaft 21 from shaking due to instability of the elastic member 54 or clearance between the stop rib 22 and the positioning groove 35, allowing the door body 3 to smoothly rotate in place through the first preset angle.

[0069] It can be understood that the length of the third limiting wall 38 can be determined according to the angle at which the door body 3 needs to rotate in situ.

[0070] In one embodiment, the hinge plate 2 or the door body 3 on which the limiting wall is provided is provided with a limiting groove 39 that cooperates with the limiting shaft 23. The groove wall of the limiting groove 39 serves as the limiting wall, thereby enhancing the limiting effect and further preventing the door body 3 from shaking. Of course, this is not limiting. In other embodiments, the limiting wall may also be a plate-shaped wall directly protruding from the door body 3 or the hinge plate 2.

[0071] Correspondingly, combined Figure 3-Figure 6 As shown, the limit groove 39 has a starting end, an end terminal, and a first section 391 located between the starting end and the end terminal. When the door body 3 is in a closed state, the limit shaft 23 is located at the starting end. When the door body 3 is opened from the closed state, the limit shaft 23 moves from the starting end to the end terminal.

[0072] It can be understood that the starting end and the terminal end of the limiting groove 39 correspond to the starting end and the terminal end of the limiting wall.

[0073] The first limiting wall 36 is a groove wall on the side of the first section 391 close to the long axis hole 31. After the door body 3 is opened until the hinge shaft 21 is located at the second end 312 and the electromagnet 51 is in the de-energized state, when the elastic member 54 drives the hinge shaft 21 to return from the second end 312 to the first end 311, the limiting shaft 23 abuts against the groove wall on the side of the first section 391 close to the long axis hole 31, and the limiting shaft 23 moves toward the terminal end within the first section 391. It can slow down the movement speed of the hinge shaft 21 toward the first end 311, and at the same time slow down the movement speed of the stop rib 22 toward the third groove section 354, thereby enhancing the stability of the movement of the door body 3, and preventing damage caused by collision between the hinge shaft 21 and the hole wall of the long axis hole 31 and the stop rib 22 and the groove wall of the third groove section 354, thereby reducing noise; in addition, it can enable the door body 3 to move according to a preset trajectory, that is, in the process of the door body 3 opening from the second preset angle to the third preset angle, the door body 3 rotates and translates at the same time, and when the door body 3 opens to the third preset angle, the hinge shaft 21 moves to the first end 311 at the same time, and the stop rib 22 moves completely into the third groove section 354 at the same time.

[0074] Furthermore, the limiting groove 39 also includes a second section 392 located at an end of the first section 391 closer to the starting end. The second limiting wall 37 is the groove wall on the side of the second section 392 away from the longitudinal hole 31. After the door body 3 is opened to a first predetermined angle, the electromagnet 51 is energized to drive the hinge shaft 21 from the first end 311 to the second end 312. At this time, the limiting shaft 23 abuts against the groove wall on the side of the second section 392 away from the longitudinal hole 31, and the limiting shaft 23 moves within the second section 392 toward the direction of the first section 391. It can further slow down the moving speed of the hinge shaft 21, enhance the stability of the translation of the door body 3, and avoid the hinge shaft 21 from hitting the wall of the long axis hole 31, thereby preventing damage and reducing noise; in addition, it can enable the door body 3 to move according to a preset trajectory, that is, in the process of the door body 3 opening from the first preset angle to the second preset angle, the door body 3 rotates and translates at the same time, and when the door body 3 opens to the second preset angle, the hinge shaft 21 moves to the second end 312 at the same time.

[0075] Furthermore, the limiting groove 39 includes a third section 393 connecting the starting end with the second section 392. The third limiting wall 38 is the groove wall of the third section 393 on the side away from the longitudinal hole 31. When the door body 3 is opened from the closed state to a first predetermined angle, the hinge shaft 21 remains at the first end 311, and the limiting shaft 23 moves within the third section 393 away from the starting end, causing the door body 3 to rotate in place.

[0076] Furthermore, the front wall 32 of the door body 3 is higher than the hinge plate 2, so as to achieve the purpose of concealing the hinge plate 2 and enhance the appearance of the refrigerator.

[0077] For further information, see Figure 1 As shown, the pivot end 34 of the hinge plate 2 has an avoidance portion 24 to avoid the front wall 32 of the door body 3 when the door body 3 is opened to the maximum opening angle, so that the door body 3 can be opened to the actual maximum opening angle.

[0078] To sum up, the refrigerator in the present invention drives the hinge shaft 21 and the long axis hole 31 to move relative to each other by setting a magnetic drive component 5, so as to drive the door body 3 to move horizontally. At the same time, a stop rib 22 and a positioning groove 35 are set to limit the relative movement speed between the hinge shaft 21 and the long axis hole 31, so that the door body 3 can move according to a preset trajectory. At the same time, it can prevent the hinge shaft 21 and the long axis hole 31 from colliding, thereby reducing noise.
