Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigerator. Background Art

[0002] At present, the common multi-door and double-door refrigerators on the market have two door bodies arranged side by side on the left and right corresponding to the position of the upper storage compartment of the refrigerator, namely the left door body and the right door body. In order to ensure the sealing of the inner edges of the relative parts of the two door bodies, a flip beam is often hinged on the opening side of one of the door bodies. The flip beam can be freely flipped along the rotating shaft between perpendicular to the door body and parallel to the door body. In order to ensure the correct rotation of the flip beam, a guide seat is generally provided on the top wall of the storage compartment, a guide groove is provided in the guide seat, and a guide body is provided on the top of the flip beam. The guide body cooperates with the guide groove to guide the flip beam to rotate correctly according to the predetermined trajectory during the process of opening or closing the door. When the door body is opened, the flip beam rotates along the guide groove to become perpendicular to the door body; when the door body is closed, the flip beam rotates along the guide groove to become parallel to the door body, so that it can be precisely matched with the seals on the left door body and the right door body, thereby preventing cold leakage between the door bodies.

[0003] When the door is open, the self-locking structure is set on the flip beam to maintain the position of the flip beam and prevent the flip beam from flipping due to external force, which may cause the door to fail to close normally. The self-locking structure is usually locked, and it cannot be unlocked without manually pressing the guide body on the top of the flip beam. If a new user does not understand the self-locking function and forcibly turns the flip beam in the self-locking state by hand, it will cause damage to the internal structural parts of the flip beam.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0005] In view of the problems pointed out in the background technology, the utility model provides a refrigerator, in which a flip beam in a self-locking state can automatically release the self-locking when subjected to an external force, thereby avoiding damage to the internal structure of the flip beam.

[0006] In order to achieve the above-mentioned utility model purpose, the utility model adopts the following technical solutions:

[0007] In some embodiments, a refrigerator is provided, comprising:

[0008] a box body, in which a refrigerated space is formed;

[0009] Two opposing door bodies, which are rotatably connected to the box body;

[0010] A turning beam, which is rotatably arranged on the side of one of the door bodies, comprises:

[0012] A hinge assembly, which is arranged between the door body and the flip beam, and a first limiting portion is provided on the hinge assembly;

[0013] The locking assembly comprises a moving part and a resetting part, wherein one end of the moving part is provided with a second limiting portion, wherein:

[0014] When the moving member moves in a direction away from the top of the flip beam under the pressure of the guide assembly, the reset member is compressed and the second limiting portion is separated from the first limiting portion;

[0015] When the moving member moves toward the top direction of the flip beam under the action of the restoring force of the restoring member, the second limiting portion is connected to the first limiting portion to lock the flip beam;

[0016] When the flip beam in the locked state is flipped by an external force, the second limiting portion can be separated from the first limiting portion.

[0017] After the door is opened, the first limiting part is connected to the second limiting part, and the flip beam is locked. If the flip beam is flipped by external force, the second limiting part can be smoothly separated from the first limiting part, and the flip beam is unlocked, avoiding damage to the internal structural parts of the flip beam.

[0018] In some embodiments, a refrigerator is provided, comprising:

[0019] a box body, in which a refrigerated space is formed;

[0020] Two opposing door bodies, which are rotatably connected to the box body;

[0021] A turning beam, which is rotatably arranged on the side of one of the door bodies, comprises:

[0025] A position detection component includes a magnetic attraction portion and a reed switch. The magnetic attraction portion is arranged on one of the flip beam and the door body, and the reed switch is arranged on the other. The position detection component is used to detect the flipping state of the flip beam.

[0026] The position detection component detects the position state of the flip beam. If the flip beam is detected to be away from the door body when the door body is about to be closed, that is, the flip beam is not in the first flip position state perpendicular to the door body, the control system will issue a sound or animation reminder to remind the user to flip the flip beam to the first flip position state to facilitate the smooth closing of the door body.

[0059] The present application provides a refrigerator, referring to Figure 1 , which includes a box body 10, in which a refrigerated space is formed to provide suitable temperature and humidity for food storage.

[0060] The refrigerator includes two door bodies 20 that open opposite to each other, which are denoted as a left door body and a right door body. The left door body and the right door body are rotatably connected to the corresponding sides of the box body 10. When both the left door body and the right door body are closed, the refrigerated space is closed. When one of the left door body and the right door body is opened, the refrigerated space is opened.

[0061] The refrigerator includes a flip beam 30, which is rotatably arranged on the side of one of the door bodies 20. The flip beam 30 is used to close the gap between the two closed door bodies 20, ensure that the inner edges of the opposing parts of the two door bodies 20 are sealed, prevent the refrigerated space from leaking cold, and ensure the refrigeration effect of the refrigerated space.

[0062] Figure 1 In a specific embodiment shown, the flip beam 30 is rotatably disposed on the side of the left door body.

[0063] The flip beam 30 rotates relative to the door body 20 , and the flip beam 30 has a first flip position state and a second flip position state.

[0064] When the door body 20 is opened, the flip beam 30 rotates to a state perpendicular to the door body 20, which is the first flip position state. Figures 2 to 4shown.

[0065] When the door body 20 is closed, the flip beam 30 rotates to a state parallel to the door body 20 , which is a second flip position state, not shown in the figure.

[0066] When the door body 20 is opened, in order to maintain the first flip position of the flip beam 30 and prevent the flip beam 30 from flipping due to external force and causing the door to be unable to close normally, a self-locking structure is provided on the flip beam 30. The self-locking structure is generally locked, and cannot be unlocked without manually pressing the guide body 110 on the top of the flip beam 30. If a new user does not understand the self-locking function and forcibly turns the flip beam 30 in the self-locking state by hand, the internal structural parts of the flip beam 30 will be damaged.

[0067] In order to solve the above technical problems, the present embodiment improves the structure of the flip beam 30 so that the flip beam 30 in the self-locking state can automatically release the self-locking when subjected to external force, thereby avoiding damage to the internal structure of the flip beam 30.

[0068] Specifically, the structure of the flip beam 30 is as follows Figures 2 to 6 The flip beam 30 includes a shell 500, and a cavity is formed inside the shell 500, which serves as a mounting carrier for other structural components. Figure 3 and Figure 6 In the schematic diagram shown, one side wall of the housing 500 is hidden so as to show the internal structure of the flip beam 30 .

[0069] The flip beam 30 includes a guide assembly 100, and the guide assembly 100 is disposed between the door body 20 and the flip beam 30. The guide assembly 100 is used to make the flip beam 30 rotate according to a predetermined track.

[0070] In a specific embodiment, the guide assembly 100 includes a guide groove 120 and a guide body 110. The guide groove 120 is fixedly disposed on the box body 10, and the guide body 110 is disposed on the flip beam 30. The guide body 110 is disposed on the top of the flip beam 30.

[0071] When the door body 20 is closed, the guide body 110 is located in the guide groove 120 , the flip beam 30 is parallel to the door body 20 , and the flip beam 30 is locked in a second flip position state parallel to the door body 20 .

[0072] When the door 20 is opened, the guide body 110 moves along the track of the guide groove 120, thereby realizing the movement of the flip beam 30 along the predetermined track. When the guide body 110 moves along the track of the guide groove 120, the flip beam 30 rotates relative to the door 20.

[0073] When the guide body 110 is separated from the guide groove 120 , the flip beam 30 rotates to a first flip position state perpendicular to the door body 20 .

[0074] When the door body 20 is closed from an open state, as the door body 20 rotates, the guide body 110 enters the guide groove 120, and the guide body 110 moves along the trajectory of the guide groove 120, so that the flip beam 30 flips to a second flip position state parallel to the door body 20.

[0075] When the guide body 110 moves along the track of the guide groove 120 , the guide body 110 can synchronously move downward relative to the flip beam 30 .

[0076] A mounting opening 580 for mounting the guide body 110 is provided at the top of the shell 500 of the flip beam 30 . The guide body 110 is disposed in the mounting opening 580 . When the guide body 110 moves along the track of the guide groove 120 , the guide body 110 moves downward along the mounting opening 580 .

[0077] When the guide body 110 moves along the track of the guide groove 120 , the guide groove 120 applies pressure to the guide body 110 , causing the guide body 110 to move downward.

[0078] The flip beam 30 includes a hinge assembly 200, and the hinge assembly 200 is disposed between the door body 20 and the flip beam 30. The hinge assembly 200 is used to realize the rotation connection between the flip beam 30 and the door body 20.

[0079] The flip beam 30 includes a locking assembly 300 , and the locking assembly 300 is used to lock the flip beam 30 in the first flip position.

[0080] The locking assembly 300 includes a moving member 310, which is disposed in the inner cavity of the flip beam 30. The moving member 310 moves along the height direction of the flip beam 30 under the action of an external force. It can be understood that the moving member 310 can move upward or downward under the action of an external force.

[0081] The upward movement of the moving member 310 refers to the movement of the moving member 310 toward the top of the flip beam 30. The downward movement of the moving member 310 refers to the movement of the moving member 310 away from the top of the flip beam 30, that is, the movement of the moving member 310 toward the bottom of the flip beam 30.

[0082] When the guide body 110 moves along the track of the guide groove 120 , the guide body 110 moves downward, and the guide body 110 applies pressure to the moving member 310 , so that the moving member 310 moves downward.

[0083] The locking assembly 300 includes a reset member 320 , which is disposed in the inner cavity of the flip beam 30 . The reset member 320 is used to apply a force to the moving member 310 to move the moving member 310 toward the top of the flip beam 30 .

[0084] Taking the door opening process as an example, when the door is opened, the guide body 110 moves along the track of the guide groove 120, and the guide body 110 moves downward. The guide body 110 applies pressure to the moving member 310, so that the moving member 310 moves downward, and the reset member 320 is compressed by force.

[0085] When the door body 20 is opened to a certain angle, the guide body 110 is separated from the guide groove 120, the force of the guide groove 120 on the guide body 110 is released, the reset member 320 applies an upward elastic force to the movable member 310, the movable member 310 moves upward, and the movable member 310 pushes the guide body 110 to move upward.

[0086] In one specific embodiment, the reset member 320 is a spring.

[0087] The locking of the flip beam 30 in the first flip position state perpendicular to the door body 20 is achieved by the cooperation of the first limiting portion 214 and the second limiting portion 313 .

[0088] Specifically, the hinge assembly 200 is provided with a first limiting portion 214 . One end of the moving member 310 is provided with a second limiting portion 313 .

[0089] When the first position-limiting portion 214 is connected to the second position-limiting portion 313 , the flip beam 30 is locked in a first flip position state perpendicular to the door body 20 .

[0090] When the first limiting portion 214 is separated from the second limiting portion 313 , the flip beam 30 can rotate relative to the door body 20 .

[0091] When the moving member 310 moves in a direction away from the top of the flip beam 30 under the pressure of the guide assembly 100 , the reset member 320 is compressed and the second limiting portion 313 is separated from the first limiting portion 214 .

[0092] When the moving member 310 moves toward the top of the flip beam 30 under the action of the restoring force of the restoring member 320 , the second limiting portion 313 is connected to the first limiting portion 214 to lock the flip beam 30 .

[0093] The cooperation between the first limit portion 214 and the second limit portion 313 is combined with the flipping action of the flip beam 30, which does not interfere with the normal opening and closing of the door body 20 and the flipping action of the flip beam 30. After the door body 20 is opened, the automatic locking of the flip beam 30 is achieved.

[0094] After the door 20 is opened, the flip beam 30 is locked because the first limit portion 214 is connected to the second limit portion 313. If the flip beam 30 is flipped by an external force, the second limit portion 313 can smoothly separate from the first limit portion 214, and the flip beam 30 is unlocked, thereby preventing the internal structural parts of the flip beam 30 from being damaged by force.

[0095] In some embodiments, reference Figure 6 The hinge assembly 200 includes a fixed hinge part 210 and a movable hinge part 220. The fixed hinge part 210 and the movable hinge part 220 are hinged via mutually matching cam surfaces. The fixed hinge part 210 is fixedly connected to the door body 20, and the movable hinge part 220 is connected to the flip beam 30.

[0096] The structure of the fixed hinge part 210 is as follows: Fig.10 and Fig.11 As shown, the structure of the movable hinge 220 is as follows Fig.12 shown.

[0097] A first cam surface 213 is provided at one end of the fixed hinge part 210, and a second cam surface 223 is provided at one end of the movable hinge part 220. Through the rotatable cooperation between the first cam surface 213 and the second cam surface 223, the rotational connection between the fixed hinge part 210 and the movable hinge part 220 is realized, thereby realizing the rotation of the flip beam 30 relative to the door body 20.

[0098] In a specific embodiment, the fixed hinge part 210 is disposed below the movable hinge part 220 , the upper end of the fixed hinge part 210 is provided with a first cam surface 213 , and the lower end of the movable hinge part 220 is provided with a second cam surface 223 .

[0099] The fixed hinge part 210 is fixedly connected to the door body 20 , and the height position of the fixed hinge part 210 relative to the flip beam 30 is fixed. When the flip beam 30 rotates, the flip beam 30 rotates relative to the fixed hinge part 210 .

[0100] The height position of the movable hinge 220 relative to the flip beam 30 is variable, while the angular position of the movable hinge 220 relative to the flip beam 30 is constant.

[0101] In order to achieve the rotatable cooperation between the fixed hinge part 210 and the movable hinge part 220, the movable hinge part 220 can move up and down relative to the height direction of the flip beam 30. In addition, the movable hinge part 220 and the flip beam 30 can transmit torque.

[0102] When the guide groove 120 cooperates with the guide body 110 for guidance, the flip beam 30 drives the movable hinge 220 to rotate under the action of the guide force, and the movable hinge 220 moves upward along the cam surface. When the flip beam 30 rotates to the highest point of the cam surface and continues to rotate, the movable hinge shaft moves downward under the action of its gravity and rotates under the action of the cam surface to apply a rotational force to the flip beam 30, thereby achieving the purpose of saving effort during the process of opening or closing the door body 20.

[0103] In some embodiments, reference Fig.10 and Fig.11The fixed hinge part 210 includes a fixed hinge first part 211 and a fixed hinge second part 212 of an integrated structure. A first cam surface 213 is disposed at one end of the fixed hinge first part 211, and a first position limiting part 214 is disposed at one end of the fixed hinge second part 212.

[0104] Reference Fig.12 The movable hinge part 220 includes an integral movable hinge part 1 221 and a movable hinge part 222. One end of the movable hinge part 221 is provided with a second cam surface 223, and one end of the movable hinge part 222 is connected to the flip beam 30.

[0105] Combination Fig.13 The fixed hinge part 211 is fixedly connected to the door body 20. An extension part 215 is provided on the fixed hinge part 211, an opening is provided on the housing 500 of the flip beam 30, and the extension part 215 extends through the opening. The extension part 215 is fixedly connected to the door body 20 to achieve a fixed connection between the fixed hinge part 210 and the door body 20.

[0106] The housing 500 is provided with a first mounting hole 513, and the second fixed hinge part 212 is inserted into the first mounting hole 513. When the flip beam 30 rotates, the second fixed hinge part 212 rotates in the first mounting hole 513.

[0107] The housing 500 is provided with a second mounting hole 514 , and the second movable hinge part 222 is penetrated in the second mounting hole 514 . The second movable hinge part 222 can transmit torque to the second mounting hole 514 , and the second movable hinge part 222 moves along the axial direction of the second mounting hole 514 .

[0108] In some embodiments, when the flip beam 30 rotates to the highest point of the cam surface and continues to rotate, in order to increase the force used to drive the movable hinge 220 to move downward, refer to Figure 6 A step is formed between the movable hinge part 121 and the movable hinge part 222 , and a compression spring 230 is sleeved on the movable hinge part 222 . The compression spring 230 is located between the step and the second mounting hole 514 .

[0109] During the upward movement of the movable hinge 220 along the cam surface, the compression spring 230 generates compression deformation and accumulates a certain elastic force. During the rotation of the flip beam 30 to the highest point of the cam surface and continues to rotate, this elastic force can drive the movable hinge 220 to move downward and make the movable hinge 220 rotate under the action of the cam surface to apply a stable rotational force to the flip beam 30.

[0110] In some embodiments, in order to allow torque to be transmitted between the second movable hinge part 222 and the second mounting hole 514, the second movable hinge part 222 is a polygonal shaft, such as a hexagon, and the second mounting hole 514 is a polygonal hole. In this way, the movable hinge part 220 is effectively prevented from rotating in the second mounting hole 514, so that torque can be transmitted between the movable hinge part 220 and the second mounting hole 514.

[0111] In some embodiments, reference Fig.11 A notch 2141 is disposed at one end of the fixed hinged second part 212 , and the notch 2141 forms a first limiting part 214 .

[0112] Reference Figure 7 A protrusion 3131 is disposed at one end of the moving member 310 , the protrusion 3131 forms a second limiting portion 313 , and an inclined surface 3132 is disposed on the protrusion 3131 .

[0113] When the movable member 310 moves upward under the action of the reset member 320, the movable member 310 moves toward the top direction close to the flip beam 30, and the protrusion 3131 is inserted into the notch 2141 from bottom to bottom, thereby realizing the connection between the movable member 310 and the fixed hinge part 210 and locking the flip beam 30.

[0114] When the moving member 310 moves downward under the action of the guide body 110 , the moving member 310 moves away from the top of the flip beam 30 , and the protrusion 3131 is separated from the notch 2141 from top to bottom, and the flip beam 30 is unlocked.

[0115] When the flip beam 30 in the locked state is flipped by an external force, the side wall of the notch 2141 moves along the inclined surface 3132 so that the protrusion 3131 is separated from the notch 2141 .

[0116] The provision of the inclined surface 3132 enables the movable member 310 to be separated from the fixed hinge portion 210 when the flip beam 30 in the locked state is flipped by an external force, thereby releasing the lock of the flip beam 30 .

[0117] Since the protrusion 3131 has an inclined surface, there is a maximum self-locking force F=F1×tanθ, where F1 is the elastic force of the reset member 320 and θ is the inclination angle of the inclined surface 3132. When the user's turning force is greater than F, the flip beam 30 will automatically release the self-locking.

[0118] The inclination angle θ of the inclined surface 3132 is greater than 30°. If it is too small, the self-locking effect cannot be achieved.

[0119] The inclination angle θ of the inclined surface 3132 is less than 80°. If it is too large, the self-locking force will be too strong and the strength of the part cannot withstand it.

[0120] In some embodiments, reference Fig.10 A first inner wall surface 2143 and a second inner wall surface 2144 are provided on the inner wall of the notch 2141 . An edge portion 2142 is formed at the intersection of the first inner wall surface 2143 and the second inner wall surface 2144 . The edge portion 2142 is used to abut against the inclined surface 3132 .

[0121] The edge portion 2142 abuts against the inclined surface 3132 to reduce the effective area between the inner wall of the notch 2141 and the inclined surface 3132 , which helps to reduce friction.

[0122] In some embodiments, reference Figure 8 The moving member 310 includes a first moving member section 311 and a second moving member section 312 of an integrated structure. The moving member 310 is an L-shaped structure, and the second moving member section 312 is disposed at the bottom end of the first moving member section 311. A protrusion 3131 is disposed on the upper surface of the second moving member section 312.

[0123] Combination Figure 6 The first moving member section 311 is extended along the height direction of the flip beam 30 , and the second moving member section 312 is extended from the first moving member section 311 toward the direction close to the notch 2141 .

[0124] One end of the first section 311 of the moving member is used to abut against the guide assembly 100. Specifically, the top of the first section 311 of the moving member acts on the guide body 110. When the guide body 110 moves along the guide groove 120, the guide body 110 moves downward, the guide body 110 abuts against the top of the first section 311 of the moving member, and pushes the first section 311 of the moving member to move downward. The moving member 310 moves downward, and the protrusion 3131 moves downward and disengages from the notch 2141.

[0125] In some embodiments, reference Fig.13 The housing 500 of the flip beam 30 is provided with a first installation cavity 510 and a second installation cavity 520.

The second installation cavity section 1 521, the second installation cavity section 2 522, and the second installation cavity section 3 523 are connected.

[0132] An installation opening 580 for installing the guide body 110 is provided on the top wall of the housing 500 , and the guide body 110 extends into the first section 521 of the second installation cavity.

[0133] The moving member 310 is disposed in the second installation cavity 520, and the moving member 310 moves along the second installation cavity 520. Specifically, the first moving member 311 is disposed in the second installation cavity 522, and the second moving member 312 is disposed in the third second installation cavity 523.

[0134] When the first section 311 of the moving part moves along the height direction of the second installation cavity second section 522, the first flange 530 and the second flange second section 542 limit and guide the up and down movement of the moving part 310, thereby preventing the moving part 310 from deflecting during the up and down movement.

[0135] In some embodiments, reference Figure 8 and Fig. 9 A cavity 314 is provided in a section 311 of the moving part, and a reset member 320 is provided in the cavity 314. A section 311 of the moving part is provided with a flange on one side thereof to form a cavity 314 with an open side, and the cavity 314 provides an installation space for the reset member 320, and also helps to improve the structural strength of the moving part 310 and reduce the weight.

[0136] A first mounting portion 316 is disposed in the cavity 314. Fig.13A second mounting portion 550 is disposed in the housing 500 of the flip beam 30 , and the reset member 320 is disposed between the first mounting portion 316 and the second mounting portion 550 .

[0137] Specifically, the second mounting portion 550 is disposed in the second mounting cavity section 522, and an opening 315 is disposed on the wall of the first moving member section 311, that is, an opening 315 is disposed on the flange of the cavity 314 forming the moving member 310, and the second mounting portion 550 extends into the cavity 314 through the opening 315. The reset member 320 is vertically disposed between the first mounting portion 316 and the second mounting portion 550.

[0138] In some embodiments, reference Fig.14 and Fig.15 The refrigerator also includes a position detection component 400, which includes a magnetic portion 410 and a reed switch 420. The magnetic portion 410 is provided on one of the flip beam 30 and the door body 20, and the reed switch 420 is provided on the other.

[0139] When the door body 20 is opened, the flip beam 30 is in a first flip position perpendicular to the door body 20 , the flip beam 30 is close to the door body 20 , the magnetic attraction portion 410 and the reed switch 420 are close to each other, and the magnetic attraction portion 410 attracts the reed switch 420 to conduct.

[0140] At this time, if the user bends the flip beam 30 to release the self-locking state, that is, the flip beam 30 rotates to the second flip position state parallel to the door body 20, the magnetic attraction part 410 is separated from the reed switch 420 and disconnected. The control panel receives the signal and starts to issue an alarm or screen animation to remind the user to restore the flip beam 30 to the self-locking state.

[0141] That is to say, after the door body 20 is opened, the flip beam 30 can be locked in the first flip position state perpendicular to the door body 20. At this time, if the user forcibly bends the flip beam 30, the protrusion 3131 will be separated from the notch 2141, so that the flip beam 30 can automatically release the self-locking, thereby preventing the internal parts of the flip beam 30 from being damaged. At the same time, the position change of the flip beam 30 is detected by the magnetic attraction part 410 and the reed switch 420, reminding the user to restore the flip beam 30 to the first flip position state, so as to facilitate the smooth closing of the door body 20.

[0142] In a specific embodiment, the magnetic attraction portion 410 is disposed in the flip beam 30 , and the reed switch 420 is disposed in the inner shell of the door body 20 .

[0143] Combination Fig.13 A third installation cavity 560 is formed between the second flange 540 and one side of the flip beam 30 , and a fourth installation cavity 570 for installing the magnetic attraction portion 410 is disposed in the third installation cavity 560 .
