Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a door body assembly and a refrigeration device. Background Art

[0002] With the increasing demand for the integration of household appliances and home furnishings, the embedded design of household appliances has become a trend. Most refrigerators on the market currently use single-axis or double-axis hinges to realize the rotational connection between the refrigerator door and the refrigerator body. This design is mainly to meet the embedding requirements of the refrigerator, ensuring that the refrigerator door does not extend beyond the side of the refrigerator during the process of opening and closing the door, thereby avoiding interference with the side cabinet wood boards.

[0003] However, in order to pursue a better home integration effect, sometimes it is necessary to fixedly connect a door panel to the surface of the box door. Although this design can reduce the integration degree of the appliance and the home, it also increases the thickness of the entire door body assembly. This results in that after the appliance is pushed into the cavity, relying only on the original single-axis or double-axis hinge, the door body assembly with the door panel may interfere with the side of the installation space body during the process of opening and closing the door, thus causing the door body assembly of the appliance to be unable to be normally opened or closed.

[0045] With the increasing demand for the integration of household appliances and home furnishings, the embedded design of household appliance products has become a trend. Most refrigerators on the market currently use single-axis or double-axis hinges to achieve the rotational connection between the refrigerator door and the refrigerator body. This design is mainly to meet the embedding requirements of the refrigerator and ensure that the refrigerator door body does not exceed the side of the refrigerator during the process of opening and closing the door, thereby avoiding interference with the side cabinet wood boards.

[0046] However, in order to pursue a better home integration effect, sometimes it is necessary to fixedly connect a door panel to the surface of the door of the box. Although this design can reduce the integration degree of the electrical appliance and the home furnishings, it also increases the thickness of the entire door body assembly at the same time. This results in that after the electrical appliance is pushed into the cavity, relying only on the original single-axis or double-axis hinge, the door body assembly with the door panel may interfere with the side of the installation space body during the process of opening and closing the door, thereby causing the door body assembly of the electrical appliance to be unable to be opened or closed normally.

[0047] The following refers to Figure 1 , and through specific embodiments and their application scenarios, the door body assembly and refrigeration equipment provided by the embodiments of the present utility model.

[0048] In the first aspect, as Figure 1 shown, an embodiment of the present utility model provides a door body assembly. The door body assembly includes a box door 10, a door panel 30, a driving assembly 40, a driven assembly 50, and a magnetic coupling mechanism 60. The box door 10 is rotatably connected to the electrical appliance main body 20 and is adapted to open or close the storage space of the electrical appliance main body 20; the door panel 30 is slidably arranged on the outside of the box door 10; the driving assembly 40 is arranged on one of the box door 10 or the door panel 30, and the driven assembly 50 is connected to the other; the magnetic coupling mechanism 60 includes a driving magnet 61 and a driven magnet 62, and the driving magnet 61 is connected to the driving assembly 40; the driving assembly 40 is adapted to drive the driving magnet 61 to rotate and drive the driven magnet 62 to rotate, and the driven magnet 62 is connected to the driven assembly 50 to drive the door panel 30 to move relative to the box door 10 through the driven assembly 50.

[0049] The door 10 of the cabinet is a part of the electrical appliance main body 20 (such as a refrigerator), and is used to open or close the storage space of the electrical appliance main body 20. The door 10 can be an object directly operated by the user, and is controlled to open and close the storage space by rotation.

[0050] The door panel 30 is arranged on the outer side of the door 10 of the cabinet and can slide along the door 10 of the cabinet. The user can open or close the door 10 of the cabinet by pushing the door panel 30. The design of the door panel 30 can improve the consistency and aesthetics of the overall appearance, and by opening in a sliding rather than a rotating manner, the required space can be reduced.

[0051] The drive assembly 40 is responsible for receiving external instructions (such as user operations or actions detected by the sensor 70) and converting them into mechanical energy. It can be a motor or other form of power source. The drive assembly 40 indirectly drives the movement of the door panel 30 by rotating the active magnet 61.

[0052] The driven assembly 50 is used in cooperation with the drive assembly 40 and is connected to the door panel 30. When the drive assembly 40 works, the driven assembly 50 will transmit power to the door panel 30, enabling the door panel 30 to move relative to the door 10 of the cabinet. The driven assembly 50 can include a connecting rod 522, a slider 521, etc., to ensure that the door panel 30 moves smoothly along a predetermined trajectory.

[0053] The magnetic coupling mechanism 60 is a key component connecting the drive assembly 40 and the driven assembly 50, and is composed of an active magnet 61 and a driven magnet 62. When the drive assembly 40 drives the active magnet 61 to rotate, the active magnet 61 drives the driven magnet 62 to rotate through magnetic action. The non-contact power transmission method reduces mechanical wear and improves the reliability and lifespan of the system.

[0054] The active magnet 61 is connected to the drive assembly 40 and rotates under the drive of the drive assembly 40. Its rotational motion will be transmitted to the driven magnet 62 through magnetic action, thereby indirectly driving the movement of the door panel 30.

[0055] The driven magnet 62 is connected to the driven assembly 50 and rotates with the rotation of the active magnet 61 through the magnetic action of the magnetic coupling mechanism 60. The rotation of the driven magnet 62 is transmitted to the door panel 30 through the driven assembly 50, thereby driving the door panel 30 to move relative to the door 10 of the cabinet.

[0056] In this application, the driving component 40 is provided on one of the cabinet door 10 or the door panel 30, the driven component 50 is connected to the other one. At the same time, the driving magnet 61 of the magnetic coupling mechanism 60 is connected to the driving component 40; the driving component 40 is adapted to drive the driving magnet 61 to rotate and drive the driven magnet 62 to rotate, and the driven magnet 62 is connected to the driven component 50 to drive the door panel 30 to move relative to the cabinet door 10 through the driven component 50; when a user or an external mechanism (such as a sensor 70 detecting an opening action) triggers the driving component 40, the driving component 40 will drive the driving magnet 61 to rotate. The rotation of the driving magnet 61 drives the driven magnet 62 to rotate through magnetic action. The rotation of the driven magnet 62 is transmitted to the door panel 30 through the driven component 50, thereby driving the door panel 30 to move relative to the cabinet door 10. While ensuring that the decorative panel can be normally closed, it avoids interference between the door panel 30 and the cabinet body around the refrigeration equipment.

[0057] Furthermore, the door body assembly of the present utility model reduces mechanical wear by using a non-contact magnetic transmission method, and improves the reliability and service life of the system.

[0058] Referring to Figure 1 , in some embodiments, the driving magnet 61 and the driven magnet 62 are arranged at intervals.

[0059] It can be understood that in this embodiment, the driving magnet 61 and the driven magnet 62 are not in direct contact, but maintain a certain distance. The driving magnet 61 generates a magnetic field change through its own rotation, and this changing magnetic field will act on the driven magnet 62 even if there is a certain distance between them. This non-contact transmission method can avoid mechanical wear and can adapt to application requirements in different environments. It reduces the direct friction between mechanical components, reduces the maintenance cost, and improves the reliability and service life of the system.

[0060] Referring to Figure 1 , in some embodiments, the driving magnet 61 and the driven magnet 62 are coaxially arranged.

[0061] It can be understood that in this embodiment, the driving magnet 61 and the driven magnet 62 are located on the same axis. Usually, they are arranged coaxially, but still maintain a certain interval to ensure that they will not be in direct contact. The magnetic field change generated when the driving magnet 61 rotates will directly act on the coaxially arranged driven magnet 62, causing it to rotate accordingly. Although they are on the same axis, due to the action of the magnetic field, they do not need to be in physical contact to transmit power. The coaxial arrangement can ensure that the magnetic field action between the magnets is more stable and efficient, and at the same time can reduce the system volume, making the overall design more compact.

[0062] Referring to Figure 1, in some embodiments, the magnetic coupling mechanism 60 further includes an isolator 63 adapted to isolate the driving magnet 61 from the driven magnet 62.

[0063] It can be understood that, in this embodiment, the main purpose of setting the isolator 63 is to establish a physical barrier between the driving magnet 61 and the driven magnet 62 to prevent them from directly contacting. This helps to reduce the wear between the driving magnet 61 and the driven magnet 62 and improve the reliability and service life of the system. Although the isolator 63 isolates the driving magnet 61 from the driven magnet 62, it allows the magnetic field to pass through, enabling the rotation of the driving magnet 61 to be transmitted to the driven magnet 62 through the change of the magnetic field. Thus, through the action of the isolator 63, the rotation of the driving magnet 61 can drive the rotation of the driven magnet 62 without physical contact, thereby reducing mechanical wear and improving the reliability and service life of the system. At the same time, the presence of the isolator 63 also ensures the relative position stability between the driving magnet 61 and the driven magnet 62, making it not easy to displace even during operation, and improving the transmission accuracy and stability.

[0064] Refer to Figure 1 , in some embodiments, along the sliding direction of the door panel 30 relative to the box door 10, a driving assembly 40, a driving magnet 61, a driven magnet 62, and a driven assembly 50 are sequentially arranged.

[0065] It can be understood that the driving assembly 40 is located at the forefront and is responsible for receiving external signals (such as user operations or sensor 70 signals) and converting them into power output. The driving magnet 61 is adjacent to the driving assembly 40 and rotates by the power provided by the driving assembly 40. The driven magnet 62 is located behind the driving magnet 61 and rotates following the driving magnet 61 through magnetic coupling. The driven assembly 50 is located behind the driven magnet 62 and is responsible for converting the rotational motion of the driven magnet 62 into the translational motion of the door panel 30. This structural arrangement can achieve non-contact power transmission while simplifying the structure, saving space, and improving the reliability and service life of the system.

[0066] Refer to Figure 1 , in some embodiments, the driving magnet 61 includes a first magnetic portion 611 and a driving shaft 612, and the driving assembly 40 is connected to the driving shaft 612 and is adapted to drive the driving shaft 612 to rotate to drive the rotation of the first magnetic portion 611.

[0067] In this embodiment, the first magnetic part 611 is the main component of the active magnet 61. It is usually made of magnetic material and has multiple magnetic poles (such as N poles and S poles). The first magnetic part 611 is responsible for interacting with the driven magnet 62 through the magnetic field to achieve non-contact power transmission. The active shaft 612 is a rotating component connected to the first magnetic part 611. It is driven to rotate by the driving component 40. The rotation of the active shaft 612 will drive the first magnetic part 611 to rotate together. The driving component 40 usually includes a motor or other types of power sources, which are used to receive signals and start the entire transmission process. It is connected to the active shaft 612. When the driving component 40 is started, it will drive the active shaft 612 to rotate. The driving component 40 and the active shaft 612 are connected through an appropriate mechanical connection (such as keyway connection, threaded connection, etc.) to ensure that the active shaft 612 can accurately rotate according to the instructions of the driving component 40.

[0068] Referring to Figure 1 , in some embodiments, the driven magnet 62 includes a second magnetic part 621 and a driven shaft 622. The driven shaft 622 is connected to the driven component 50, and the second magnetic part 621 drives the driven component 50 to move through the driven shaft 622.

[0069] It can be understood that, in this embodiment, the second magnetic part 621 is the core part of the driven magnet 62. It is made of a permanent magnet and has a fixed magnetic pole distribution. The driven shaft 622 is a rotating shaft connected to the second magnetic part 621 and is used to transmit rotational power. When the active magnet 61 rotates, the changing magnetic field it generates will exert a magnetic force on the driven magnet 62, causing the second magnetic part 621 to follow the rotation of the active magnet 61. The driven shaft 622 is connected to the driven component 50. When the driven shaft 622 rotates, it will drive the driven component 50 to move, thereby realizing the movement of the door panel 30 relative to the box door 10.

[0070] In some embodiments, the driven component 50 includes a transmission mechanism 51 and a moving mechanism 52. The transmission mechanism 51 connects the driven shaft 622 and the moving mechanism 52. The moving mechanism 52 includes a slider 521, and the slider 521 is fixed relative to the door panel 30 or the box door 10.

[0071] It can be understood that the transmission mechanism 51 is connected to the driven shaft 622, and the rotation of the driven shaft 622 is transmitted to the moving mechanism 52 through the transmission mechanism 51. The moving mechanism 52 includes a slider 521. The slider 521 is fixed relative to the door panel 30 or the box door 10. When the moving mechanism 52 moves, it will drive the slider 521 to move in a specific direction. The slider 521 in the moving mechanism 52 can move along a guide rail or a specific path to ensure that the door panel 30 can move smoothly relative to the box door 10. The slider 521 is fixedly connected to the door panel 30 or the box door 10 to ensure that the door panel 30 can move accurately along a predetermined trajectory. The rotational motion of the driven shaft 622 is converted into a linear motion of the moving mechanism 52 through the transmission mechanism 51, and then the door panel 30 is driven by the slider 521 to move relative to the box door 10, finally realizing the opening or closing of the door body assembly.

[0072] Optionally, the transmission mechanism 51 can be a connecting rod 522 mechanism, a gear mechanism, a belt or chain drive, etc., which is suitable for converting rotational motion into linear motion.

[0073] Referring to Figure 1 , in some embodiments, the moving mechanism 52 further includes a connecting rod 522. The first end of the connecting rod 522 is connected to the slider 521; a chute is provided at the second end of the connecting rod 522; a slider 521 is provided on the box door 10 or the door panel 30 corresponding to the chute, or a slider 521 is provided at the second end of the connecting rod 522; a chute is provided on the box door 10 or the door panel 30 corresponding to the slider 521.

[0074] It can be understood that in this embodiment, the connecting rod 522 is used to connect the slider 521 and the door panel 30 or the box door 10, and convert the linear motion of the slider 521 into the movement of the door panel 30 relative to the box door 10. The slider 521 is connected to the first end of the connecting rod 522 and usually moves along a guide rail or a specific path. The chute is provided at the second end of the connecting rod 522 or on the box door 10 or the door panel 30 to guide the movement of the slider 521. The first end of the connecting rod 522 is connected to the slider 521, and the slider 521 usually moves along a specific guide rail or path. The chute can be provided at the second end of the connecting rod 522 or on the box door 10 or the door panel 30. When the slider 521 moves in a specific direction, it will drive the door panel 30 to move relative to the box door 10 through the connecting rod 522, realizing the opening or closing of the door body assembly.

[0075] When the user or an external mechanism (such as the sensor 70 detecting the door opening action) triggers the driving component 40, the driving component 40 drives the rotation of the driving shaft 612. The rotation of the driving shaft 612 drives the rotation of the first magnetic part 611 connected thereto. The rotation of the first magnetic part 611 drives the rotation of the driven magnet 62 through the magnetic field action. The rotation of the driven magnet 62 is transmitted to the driven component 50 through the driven shaft 622. The transmission mechanism 51 in the driven component 50 converts the rotational motion of the driven shaft 622 into a linear motion or other forms of motion of the moving mechanism 52. The slider 521 in the moving mechanism 52 moves in a specific direction, and drives the door panel 30 to move relative to the cabinet door 10 through the connecting rod 522, realizing the opening or closing of the door body assembly.

[0076] Referring to Figure 1 , in some embodiments, the door body assembly further includes a sensor 70, which is adapted to detect the movement of the door body assembly relative to the electrical appliance main body 20. The sensor 70 is connected to the driving component 40 and controls the movement of the driving component 40 based on the movement state of the door body assembly relative to the electrical appliance main body 20.

[0077] It can be understood that in this embodiment, the sensor 70 is used to detect the movement state of the door body assembly relative to the electrical appliance main body 20, such as whether the door is fully closed or in the process of opening. The sensor 70 is connected to the driving component 40 and can send a signal to the driving component 40 according to the detected movement state to control the movement of the driving component 40.

[0078] The sensor 70 monitors the position change of the door body assembly relative to the electrical appliance main body 20. When the position change of the door body assembly is detected, the sensor 70 sends a corresponding signal to the driving component 40. The driving component 40 starts or stops according to the received signal to control the opening or closing of the door body assembly. Through the integration of the sensor 70, the door body assembly can realize automatic opening and closing, improving the convenience for users. At the same time, the sensor 70 can ensure that the door body assembly opens or closes at the appropriate time, preventing accidental opening or closing and improving safety.

[0079] In a specific embodiment, when there is no door opening action from the outside, α=0°, and the box door 10 is in a closed state; when there is a door opening action from the outside, α>0°, the sensor 70 transmits a signal to the main control board 80, and the main control board 80 transmits a signal to the drive component 40, and the drive component 40 drives the active shaft 612 to move (the drive component 40 works in a high-speed state). When the first magnetic part 611 rotates driven by the motor, the second magnetic part 621 is still in a stationary state due to the friction and resistance at the beginning, and at this time, the first magnetic part 611 begins to deviate a certain distance relative to the second magnetic part 621. Due to the existence of this angle, the N pole (S pole) of the first magnetic part 611 has a pulling effect on the S pole (N pole) of the inner magnet, and at the same time, the N pole (S pole) of the first magnetic part 611 has a pushing effect on the previous N pole (S pole) of the inner magnet, so that the second magnetic part 621 has a tendency to follow the rotation and drive the driven shaft 622 to move outward. When the N pole (S pole) of the first magnetic part 611 is just located between the two poles (S pole and N pole) of the second magnetic part 621, the push-pull force generated reaches the maximum, thereby driving the second magnetic part 621 to rotate. During the transmission process, the isolating body 63 separates the first magnetic part 611 from the second magnetic part 621, and the magnetic lines of force pass through the isolating body 63 to transmit the power and movement of the first magnetic part 611 to the second magnetic part 621, thereby realizing contactless transmission. After the driven shaft 622 rotates, the force is transmitted to the driven component 50 (not limited to belt transmission, gear transmission, etc., which are intermediate devices that transmit the power of the power device to the working mechanism, etc.), and then drives the moving mechanism 52 to move. The moving mechanism 52 and the fulcrum on the box body are fixed points. The connecting rod 522 drives the slider 521 to move horizontally, driving the cabinet door to move horizontally, so that the door panel 30 and the cabinet door 10 are staggered to ensure that there is no interference in opening the door.

[0080] In some embodiments, a guide portion extending along the relative movement direction of the door panel 30 and the box door 10 is provided between the door panel 30 and the box door 10 , and the guide portion is suitable for supporting the door panel 30 .

[0081] It is understandable that the guide portion can be a guide rail, a slide groove or other forms of guide structures, depending on specific design requirements. The guide portion is usually installed on the door 10 and cooperates with the door panel 30 to ensure that the door panel 30 can move along a specific path.

[0082] When the driving assembly 40 is started, the active magnet 61 is driven to rotate, and then the driven magnet 62 is driven to rotate, and finally the door panel 30 is driven to move through the driven assembly 50. The door panel 30 moves along the guide portion during the movement process, and the guide portion ensures that the door panel 30 can move smoothly relative to the door 10 to avoid shaking or deviation from the predetermined trajectory. The guide portion ensures that the door panel 30 can move smoothly along the predetermined trajectory, thereby improving the stability and reliability of the door assembly.
