Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, and in particular to a refrigeration device and a refrigerator. Background Technology

[0002] As electromechanical control and intelligent technologies continue to expand into the home appliance sector, consumers are increasingly demanding ease of use, intelligence, and aesthetics in their appliance experiences. Automatically extendable drawers and trays, as fundamental intelligent functions of refrigerators, facilitate user access to items stored inside, and their applications are becoming increasingly widespread. Traditional refrigerators mostly use guide rails to extend drawers or trays. Optional guide rails can integrate common telescopic mechanisms such as screws and nuts, pneumatic telescopic, and hydraulic drives to achieve automatic opening and closing of the storage boxes. However, the overall automation and intelligence of the refrigerator remains at the stage of controlling individual components. Users still need to open the refrigerator door before pulling out the drawers, failing to simplify user operation and still resulting in a poor user experience. Summary of the Invention

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0041] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

It should be understood that such terms can be used interchangeably where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0043] It should be noted that in the description of this invention, terms such as "upper," "lower," "left," "right," "inner," and "outer," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0045] Traditional refrigerator storage boxes mostly use guide rails to extend drawers or trays. Optional guide rails can integrate common telescopic mechanisms such as screws and nuts, pneumatic telescopic mechanisms, and hydraulic drives to achieve automatic opening and closing of the storage boxes. However, the overall automation and intelligence of the refrigerator remains at the stage of controlling individual components. Users still need to open the refrigerator door before pulling out the drawers, which does not simplify user operation and still results in a poor user experience. Therefore, this application provides a... Figures 1 to 12The refrigeration device shown includes: a housing 1 with a storage cavity 11 having an opening; a door 2 rotatably disposed at the opening, having an open state and a closed state; a basket 3 movably disposed within the storage cavity 11, having a first state protruding from the opening and a second state retracted into the storage cavity 11; and a drive structure 7 disposed on the housing 1, capable of switching the door 2 between the open and closed states, and simultaneously switching the basket 3 between the first and second states. By using the drive structure 7 to simultaneously move the door 2 and the basket 3, the basket 3 is pushed out during the opening of the door 2 and retracted during the closing of the door 2, overcoming the technical problem in the prior art where the basket 3 can only be pulled out after the door 2 is opened, effectively improving the user experience. Furthermore, thanks to the drive structure 7, the door 2 can be automatically opened and closed by the user inputting opening and closing commands, further simplifying user operation and improving user experience.

[0046] To achieve the linkage between the door 2 and the basket 3, the refrigeration device also includes a connecting rod 4. One end of the connecting rod 4 is hinged to the door 2, and the other end is hinged to the basket 3. When the door 2 switches from the closed state to the open state, the basket 3 switches from the second state to the first state. When the door 2 rotates, the connecting rod 4 moves relative to the outside of the storage cavity 11. Since the length of the connecting rod 4 remains constant, it drives the basket 3 to move together towards the outside of the storage cavity 11, thereby enabling the basket 3 to be pulled out. Since the movement trajectory of the door 2 is rotational, while the basket 3 needs to move in a straight line for pulling out, the refrigeration device also includes a sliding structure. The sliding structure is disposed within the storage cavity 11, and it can drive the basket 3 to move between the first state and the second state. A sliding structure is used to limit the movement of the basketball hoop 3, ensuring that the basketball hoop 3 can only move in a straight line, preventing it from moving obliquely within the storage cavity 11 and colliding with the side wall of the storage cavity 11. Preferably, the sliding structure includes a first sliding groove 51, which has a first end 511 and a second end 512 opposite to each other. The first end 511 is located on the side of the second end 512 closer to the opening. A sliding member 31 is provided on the basketball hoop 3, which is movably disposed within the first sliding groove 51. When the basketball hoop 3 is in the first state, the sliding member 31 is located at the first end 511, and when the basketball hoop 3 is in the second state, the sliding member 31 is located at the second end 512. By utilizing the limiting function of the first end 511 and the second end 512 of the first slide groove 51, the basket frame 3 can be moved in a straight line while limiting the movement distance of the basket frame 3. This prevents the basket frame 3 from moving too far into the storage cavity 11 and colliding with it, and also prevents the basket frame 3 from moving too far out of the storage cavity 11 and falling off, thus ensuring the reliable movement of the basket frame 3.

[0047] To further improve the ease of accessing items on the basket rack 3, the refrigeration device also includes a rotating structure mounted on the housing 1. This rotating structure enables the basket rack 3 to rotate. The basket rack 3 has a first side and a second side. The rotating structure allows the basket rack 3 to switch between a state where the first side faces the opening and a state where the second side faces the opening. When the first side of the basket rack 3 faces the opening, items on the corresponding half of that side are exposed at the opening for easy access. Similarly, when the second side of the basket rack 3 faces the opening, items on the corresponding half of that side are exposed, further enhancing the user experience. To ensure that the rotation of the basketball hoop 3 is synchronized with the rotation of the gate 2, a connecting rod 4 can be used to transmit the rotation of the gate 2 to the basketball hoop 3. This allows the gate 2 to continue moving the basketball hoop 3 via the connecting rod 4, enabling the basketball hoop 3 to engage with the rotating structure. This allows the rotating structure to rotate based on the movement of the basketball hoop 3, ensuring reliable rotation of the basketball hoop 3. In one embodiment, the rotating structure includes a second slide groove 52, which is connected to the first end 511 of the first slide groove 51. A rack 53 is provided on the second slide groove 52, and a gear 32 is provided on the sliding member 31. The gear 32 can mesh with the rack 53. Since the second slide groove 52 and the first slide groove 51 are interconnected, the sliding member 31 can slide directly from the first end 511 of the first slide groove 51 into the second slide groove 52, so that the gear 32 on the sliding member 31 can contact and mesh with the rack 53. Since the rack 53 is fixed, the gear 32 can only rotate, thereby driving the sliding member 31 and the basket frame 3 to rotate.

[0048] To facilitate the design of the sliding and rotating structures of the basket frame 3, the refrigeration equipment also includes a partition plate 6. The partition plate 6 is disposed within the housing 1, and together with the housing 1, it forms the storage cavity 11. The first sliding groove 51 and the second sliding groove 52 are both disposed on the partition plate 6. The partition plate 6 not only divides the space within the housing 1 to form multiple storage cavities 11, but also allows for the fixing of the basket frame 3 in the middle of the housing 1, ensuring reliable sliding and rotation of the basket frame 3. Figure 2 As shown, the basketball hoop 3 is located above the partition plate 6, while the sliding member 31 is located below the partition plate 6. The first sliding groove 51 and the second sliding groove 52 are both provided on the lower side of the partition plate 6. The sliding member 31 can restrict the basketball hoop 3 from detaching from the partition plate 6, and can also cooperate with the first sliding groove 51 and the second sliding groove 52 to ensure reliable movement of the basketball hoop 3.

[0049] When the door body 2 is at the first preset angle, the sliding member 31 is located at the first end 511 of the first slide groove 51, and when the door body 2 is at the second preset angle, the sliding member 31 is located at the end of the second slide groove 52 away from the first slide groove 51, and the second preset angle is greater than the first preset angle. Alternatively, the door 2 can be divided into two sections, from its closed state to its maximum open angle. During the first rotation of the door 2, the door 2 only moves the basket 3 linearly. At this point, the door 2 has opened to the first preset angle, and the opening is sufficient for the user to retrieve items from the opening. The user can then access items on the door 2 and the basket 3 facing the opening. During the second rotation of the door 2, the door 2 not only moves the basket 3, but the basket 3 also rotates under the action of the rotating structure, allowing the user to easily retrieve items behind the basket 3. Furthermore, the basket 3 is partially pulled out of the storage cavity 11, preventing interference between the basket 3 and the inner wall of the storage cavity 11, ensuring reliable rotation. Preferably, the first preset angle ranges from 80° to 100°, preferably 90°, and the second preset angle ranges from 100° to 120°, preferably 120°.

[0050] Because the refrigeration equipment may experience power outages that render the drive structure 7 inoperable, forcing users to manually open and close the door, or due to user habit, the drive structure 7 may create significant resistance when manually opening the door 2, impacting the user experience. Therefore, the refrigeration equipment also includes a clutch structure. The drive structure 7 is mounted on the housing 1 and is connected to the door 2 via the clutch structure. When the drive structure 7 needs to open or close the door 2, the clutch structure engages, causing the door 2 to rotate. When the drive structure 7 is inoperable or the door 2 is manually opened, the clutch structure disengages the drive structure 7 from the door 2 when rotation is not required. This disengagement eliminates resistance, allowing the door 2 to rotate freely, which the user can then manually open and close. Similarly, the drive structure 7 is disposed on the door body 2, and the drive structure 7 is connected to the housing 1 through the clutch structure. When the drive structure 7 needs to drive the door body 2 to open or close, the clutch structure engages and drives the door body 2 to rotate. When the drive structure 7 cannot work or the door body 2 is manually opened, the clutch structure is used to disengage the drive structure 7 from the door body 2 when the door body 2 does not need to rotate. The disengagement of the clutch structure prevents the drive structure 7 from generating resistance, and the door body 2 can rotate freely. The user can drive the door body 2 to rotate by manually opening and closing the door.

[0051] The refrigeration device further includes a first transmission gear 81 and a second transmission gear 82. The first transmission gear 81 is movably disposed on the door 2 or the housing 1, and the drive structure 7 can drive the first transmission gear 81 to rotate. The second transmission gear 82 is disposed on the housing 1 or the door 2, and the first transmission gear 81 and the second transmission gear 82 together constitute the clutch structure. The movability of the first transmission gear 81 enables the engagement and disengagement of the first transmission gear 81 and the second transmission gear 82, thereby disengaging the drive structure 7 from the door 2 or the housing 1. Specifically, the drive structure 7 includes a motor, the output shaft of which is engaged with the first transmission tooth 81. When the first transmission tooth 81 moves closer to the second transmission tooth 82, and the teeth on the first transmission tooth 81 engage with the teeth on the second transmission tooth 82, the drive structure 7 can rotate the first transmission tooth 81 to drive the second transmission tooth 82 to rotate. However, the second transmission tooth 82 is fixed to the door body 2 or the housing 1, thereby realizing the relative rotation of the door body 2 and the housing 1, and thus realizing the opening or closing of the door body 2. In order to realize the controllable movement of the first transmission tooth 81, as one embodiment, the refrigeration device also includes a magnetic mechanism 83. The magnetic mechanism 83 is disposed on the door body 2 or the housing 1, and the magnetic mechanism 83 can drive the first transmission tooth 81 to move along the central axis direction of the first transmission tooth 81. When the magnetic mechanism 83 is energized, it generates a magnetic field. This magnetic field attracts the first transmission tooth 81 towards the second transmission tooth 82, causing them to mesh. This allows the drive structure 7 to engage with the second transmission tooth 82. When the magnetic mechanism 83 is de-energized, the magnetic field disappears, and the first transmission tooth 81 moves away from the second transmission tooth 82 under the influence of gravity or other reset structures. This causes the first transmission tooth 81 and the second transmission tooth 82 to disengage. The drive structure 7 can no longer drive the door body 2 and the housing 1 to rotate relative to each other, and the movement of the door body 2 is not hindered by the drive structure 7. This allows users to easily open and close the door manually, improving the user experience.

[0052] like Figure 4The housing 1 is provided with a door hinge 12, and the door body 2 is provided with a door hinge groove 21 and a door pivot 22. The door hinge 12 is disposed in the door hinge groove 21, and a receiving cavity 13 is formed in the door hinge 12. Part of the door pivot 22 is located in the receiving cavity 13. The drive structure 7 is disposed on the door pivot 22, and the output end of the drive structure 7 is located in the receiving cavity 13. The first transmission tooth 81 is movably disposed in the receiving cavity 13, and the second transmission tooth 82 is formed on the inner wall of the receiving cavity 13. By utilizing the cooperation between the receiving cavity 13 on the door hinge 12 and the door pivot 22, a detachable connection between the door body 2 and the housing 1 is achieved. Simultaneously, the first transmission gear 81 is positioned within the receiving cavity 13, allowing it to reliably slide within the cavity and ensuring reliable cooperation between the first transmission gear 81 and the second transmission gear 82. Furthermore, the toothed structure is directly machined on the inner wall of the receiving cavity 13, facilitating reliable transmission between the first transmission gear 81 and the door body 2 and reducing the number of parts. A magnetic mechanism 83 is positioned within the receiving cavity 13, above the toothed structure, enabling the first transmission gear 81 to move upwards under magnetic force and downwards under gravity, ensuring reliable movement of the first transmission gear 81. The magnetic mechanism 83 includes an electromagnet and an electromagnet coil. A magnetic field is reliably generated by energizing the electromagnet coil. To further ensure reliable movement of the first transmission gear 81, an armature is provided on the first transmission gear 81. The attraction of the magnetic field to the armature enhances the reliability of the first transmission gear 81's movement. The first transmission tooth 81 is provided with a mating groove. The output wheel of the motor of the drive structure 7 can be inserted into the mating groove, thereby meshing with the tooth structure in the mating groove. By utilizing the depth of the mating groove, the first transmission tooth 81 can still reliably mesh with the drive structure 7 after it moves.

[0053] There are two door bodies 2, which are symmetrically arranged at the two edges of the opening. Each door body 2 is connected to the basket frame 3 through a connecting rod 4. By rotating the two door bodies 2 synchronously, the resultant force formed by the two connecting rods 4 at the basket frame 3 is in the same direction as the sliding of the basket frame 3. This avoids the basket frame 3 tilting due to the force of the connecting rod 4 in a single direction, thereby further ensuring the reliable sliding of the basket frame 3.

[0054] Specifically, when the refrigeration equipment's control system receives the door-opening command, it energizes the electromagnetic coil. The first transmission gear 81 disengages from the slot above the motor in the drive structure 7 and moves upwards. The first transmission gear 81 meshes with the second transmission gear 82 under the action of the electromagnet. The output teeth of the motor in the drive structure 7 mesh with the second transmission gear 82. The driving force from the motor is first transmitted from the output teeth to the first transmission gear 81. As the first transmission gear 81 rotates, the door 2 rotates, causing one end of the connecting rod 4 to rotate. This further causes the other end of the connecting rod 4, which is fixed to the basket frame 3, to move on the first sliding groove 51, thus completing the linkage between the opening and closing of the door 2 and the extension and retraction of the basket frame 3. The above describes the motion under normal operating conditions.

[0055] When the automatic function is unavailable, i.e., in standby, drive malfunction, or power failure states, the electromagnet is de-energized, meaning the first transmission gear 81 disengages from the second transmission gear 82, and the door body 2 loses its motion connection with the drive structure 7. At this time, the rotation of the door body 2 will not cause the motor and other related structures of the drive structure 7 to move together, significantly reducing motion resistance and greatly reducing motion losses in the drive structure 7, thus extending its lifespan.

[0056] Link 4 is positioned on the lower end face of the partition plate 6. One rounded end of link 4 is fitted onto the sliding member 31 of the basket frame 3, while the other slotted end has a groove that engages with the link 4 post on the door body 2, thus completing the installation and fixation of link 4. The effective arrangement of link 4 connects the basket frame 3 and the door body 2, and is hidden under the partition plate 6, resulting in a simpler overall appearance.

[0057] When there are two door bodies 2, the two door bodies 2 and the two connecting rods 4 can be simplified into a combination of a symmetrical four-bar linkage 4 mechanism and a slider (slider 31). Specifically, the revolute joint is the drive structure 7 on the door body 2; rod A is the line connecting the door pivot 22 on the door body 2 to the slotted end of the connecting rod 4, which is a small segment of the door body 2 itself; rod B is the connecting rod 4; and the sliding joint is the slider 31 on the basket frame 3. The slider's movement path is the first slide groove 51 and the second slide groove 52. Due to the symmetrical arrangement of the two door bodies 2, the smooth and synchronous movement of the double door opening and closing is ensured, resulting in high consistency.

[0058] When the door 2 is opened to the first preset position, the motor stops and the basket 3 is pushed to the first end 511 of the first slide 51. The sliding member 31 does not contact the rack 53 of the rotating structure. At this time, the user can freely rotate the basket 3. The basket 3 rotates about the rotation axis of the sliding member 31, making it convenient to take out the items on it.

[0059] As the door 2 continues to open and move towards the second preset position, the gear 32 on the sliding member 31 engages with the rack 53 on the second sliding groove 52. As the door 2 continues to open, the basket 3 continues to move outward from the storage cavity 11. At this time, the rack 53 is fixed, causing the gear 32 to rotate, thus rotating the basket 3. The length and position of the rack 53 are determined by the depth between the basket 3 and the housing 1. The basket 3 must slide a safe distance before the sliding member 31 and the rack 53 can begin to engage. This safe distance is the area swept by the basket 3's rotation about the central axis of the sliding member 31, ensuring that it does not interfere with the housing 1. When the door 2 opens to the first preset angle (set to 90°), the basket 3 moves to the first end 511 of the first slide groove 51. At this time, the gear 32 of the sliding member 31 just meshes with the rack 53 of the second slide groove 52. The rotation angle of the basket 3 is controlled by the rack 53 of the second slide groove 52. By reasonably setting the transmission ratio between the gear 32 and the rack 53 of the sliding member 31, when the door 2 opens to the second preset angle (set to 120°), the back of the basket 3 can rotate to the opening to facilitate the user to take out items. When the door 2 moves in the opposite direction, the door... The movement of 2 causes the basket frame 3 to move deeper into the storage cavity 11. The gear 32 of the sliding member 31 meshes with the rack 53 in the opposite direction, causing the basket frame 3 to rotate in the opposite direction. When the sliding member 31 moves to the first end 511 of the first slide groove 51, the basket frame 3 just returns to facing the opening. Then, as the door 2 continues to move, the basket frame 3 can only be pushed along the first slide groove 51 and eventually reset to the initial state so that it can be pushed back smoothly. The user does not need to straighten and reset the basket frame 3 before closing the door, which effectively expands the volume of the basket frame 33 and can match any box depth.

[0061] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
