Description

Technical Field

[0001] This utility model relates to the field of refrigeration structure technology, and in particular to a drawer assembly and a freezer. Background Technology

[0002] In modern home life, freezers are an indispensable household appliance. Their performance and structural design play a crucial role in the user experience and the preservation of food. As people's living standards improve, their functional needs for freezers are becoming increasingly diversified. Large-capacity storage space has become the goal of many consumers, so that they can store more types and quantities of food and reduce the frequency of shopping.

[0003] However, traditional freezer drawers have fixed dimensions, making it difficult to flexibly adjust them to suit the size and shape of different foods. The current solution involves multiple pairs of slides on both sides of the freezer's interior, allowing drawers to be positioned within corresponding slides based on space requirements. However, adjusting a drawer requires sliding it completely out of one slide before it can be moved into another. This frequent disassembly and reassembly, or when the freezer is full of heavy items (such as multiple large bottles of beverages), can easily damage the slides and drawers, causing them to become stuck or even unable to close properly, severely impacting the user experience. Utility Model Content

[0041] Traditional freezer drawers have fixed dimensions, making it difficult to flexibly adjust to the size and shape of different foods. The current solution involves multiple pairs of slides on both sides of the freezer's interior, allowing drawers to be positioned within corresponding slides to meet different space requirements. However, adjusting a drawer requires sliding it completely out of one slide before it can be moved into another. This frequent disassembly and reassembly, or when the freezer is full of heavy items (such as multiple large bottles of beverages), can easily damage the slides and drawers, causing them to become stuck or even unable to close properly, severely impacting the user experience.

[0042] Therefore, this application provides a method such as Figures 1 to 6 The drawer assembly shown includes: a drawer body 1, on which a pull-out hole 11 is provided; and a limiting screw 2, which is detachably mounted on a preset structure 100 and movably mounted within the pull-out hole 11. The drawer body 1 is slidably connected to the preset structure 100 through the cooperation of the pull-out hole 11 and the limiting screw 2. By utilizing the cooperation of the limiting screw 2 and the pull-out hole 11, the drawer body 1 is supported by the limiting screw 2, ensuring the stability of the drawer assembly during the pulling process. Even if frequent pulling of the drawer body 1 causes damage to the limiting screw 2, it can be directly replaced to ensure the reliability of the drawer assembly's pulling. This avoids the problem of drawer jamming or even failure to close properly due to damage to the slide rails in existing technologies, effectively improving the reliability of the drawer assembly, facilitating the maintenance of the drawer assembly and the freezer, and enhancing the user experience.

[0043] The preset structure 100 is provided with multiple connecting structures 101, and the limiting screw 2 can be connected to any one of the connecting structures 101. When it is necessary to adjust the storage space, the drawer body 1 can be removed from the limiting screw 2, then the limiting screw 2 can be installed in the corresponding position of the preset structure 100, and then the drawer body 1 can be installed back onto the limiting screw 2. This achieves the installation of the drawer body 1 and also enables reliable adjustment of the storage space inside the freezer.

[0044] The number of limiting screws 2 is multiple, and each pull-out hole 11 corresponds one-to-one with a limiting screw 2. By setting multiple limiting screws 2, the drawer body 1 can be supported at multiple positions, further ensuring the stability of the drawer body 1 during the pulling process. Figure 1 As shown in the figure, there are four limiting screws 2, which are parallel to each other. Four pull holes 11 are provided on the four edges of the drawer body 1. Each pull hole 11 is slidably engaged with a limiting screw 2, which not only supports the drawer body 1 on all four edges, but also allows the drawer body 1 to slide reliably along the length of the limiting screw 2. This effectively improves the reliability of the support and the sliding reliability of the drawer body 1, and enhances the user experience of the preset structure 100 (such as a freezer).

[0045] Preferably, the back of the preset structure 100 is provided with a plurality of the connecting structures 101. After the limiting screw 2 is installed with the corresponding connecting structure 101, the limiting screw 2 is in a horizontal state, so that the drawer body 1 can be pulled out horizontally. The user can operate the drawer body 1 from the side of the preset structure 100, thereby improving the user experience.

[0046] Alternatively, the limiting screw 2 is tilted upwards, allowing the drawer body 1 to slide towards the back of the preset structure 100 under the action of gravity, thus preventing the drawer body 1 from moving unintentionally and ensuring the reliability of the preset structure 100.

[0047] Furthermore, the drawer body 1 is provided with a connector 12, which can slide and engage with the slide groove 102 on the preset structure 100. The sliding engagement between the connector 12 and the slide groove 102 can further improve the support effect of the drawer body 1.

[0048] The drawer assembly also includes a roller 13, which is mounted on the connector 12 and can roll in contact with the inner wall of the slide 102. By utilizing the rolling contact between the roller 13 and the inner wall of the slide 102, the friction between the connector 12 and the inner wall of the slide 102 and the friction between the pull-out hole 11 and the limiting screw 2 during the drawer body 1's operation can be reduced, ensuring stable and smooth operation of the drawer body 1 and improving the user experience.

[0049] Preferably, there are two rollers 13. One roller 13 can roll and engage with the upper side wall of the slide groove 102, and the other roller 13 can roll and engage with the lower side wall of the slide groove 102. By using two rollers 13 to roll and engage with the slide groove 102 on the upper and lower sides, the positioning accuracy between the connector 12 and the slide groove 102 is increased, and the friction between the limiting screw 2 and the pull hole 11 is reduced.

[0050] The roller 13 is movably disposed on the connector 12. The drawer assembly further includes a first drive member 3, which is movably disposed on the connector 12 and is capable of adjusting the size of the roller 13 protruding from the surface of the connector 12. The first driving component 3 is used to adjust the roller 13 to ensure reliable contact between the roller 13 and the surface of the slide 102. The position of the connector 12 within the slide 102 is further adjusted to reduce the friction force on the drawer body 1 during the pulling process, ensuring stable and smooth pulling of the drawer body 1 and improving the user experience. Furthermore, when the user does not need to pull the drawer body 1, the roller 13 can be retracted into the connector 12. At this time, the limit screw 2 supports the drawer body 1, ensuring the support effect of the drawer body 1. When the user needs to pull the drawer body 1, the first driving component 3 can be controlled to adjust the roller 13. At this time, the sliding of the drawer body 1 mainly relies on the rolling cooperation between the roller 13 and the inner wall of the slide 102, reducing the friction force between the limit screw 2 and the pull hole 11, thus reducing the force required for the drawer body 1 to be pulled out, making it more convenient for the user and improving the user experience.

[0051] The connector 12 has a cavity 121 inside. The roller 13 is movably disposed within the cavity 121, and at least a portion of the roller 13 protrudes from the connector 12. The first drive member 3 is movably disposed within the cavity 121 and is kinetically connected to the roller 13 to adjust the size of the roller 13 protruding from the connector 12. The cavity 121 is used to store the roller 13 and also to limit the movement direction of the first drive member 3, ensuring reliable driving of the roller 13 by the first drive member 3, thereby improving the reliability of the drawer assembly and the freezer.

[0052] The drawer assembly also includes a mounting member 14, which is movably disposed within the cavity 121. The moving direction of the mounting member 14 is the same as the moving direction of the roller 13. The roller 13 is rotatably disposed on the mounting member 14. The first driving member 3 is drivenly connected to the mounting member 14 to drive the mounting member 14 to move. The mounting member 14 supports the roller 13, allowing the roller 13 to move linearly under the drive of the first driving member 3 while also rolling around its own axis. This ensures rolling contact between the roller 13 and the inner wall of the slide groove 102, improving the reliability of the drawer body 1's pull-out mechanism. The connector 12 has a through hole for the roller 13 to enter and exit. The mounting member 14 is movably disposed within the through hole, allowing the roller 13 to enter and exit while also restricting the moving direction of the mounting member 14, ensuring reliable movement of the roller 13. Figure 3 As shown, the axis of the through hole in the figure is a vertical straight line. At this time, the mounting part 14 can only drive the roller 13 to move in the vertical direction, and the roller 13 also needs to move in the vertical direction to cooperate with the upper and lower surfaces of the slide groove 102.

[0053] The mounting component 14 is provided with a first guide surface 141, and the first driving component 3 is provided with a second guide surface 31. The first guide surface 141 and the second guide surface 31 are guided and engaged, and the movement of the first driving component 3 is converted into the movement of the mounting component 14 through the guiding engagement of the first guide surface 141 and the second guide surface 31. The first driving component 3 moves along the sliding direction of the drawer body 1, while the mounting component 14 can drive the roller 13 to move in a direction perpendicular to the sliding direction. At this time, the guiding engagement of the first guide surface 141 and the second guide surface 31 is required to convert the movement of the first driving component 3 into the movement of the mounting component 14, ensuring that the driving of the mounting component 14 by the first driving component 3 is reliable. Figure 3As shown, the first driving member 3 moves horizontally, and the mounting member 14 moves vertically. The first guide surface 141 of the mounting member 14 corresponding to the upper roller 13 is a plane at a downward angle of 45°, and the first guide surface 141 of the mounting member 14 corresponding to the lower roller 13 is a plane at a upward angle of 45°. The first driving member 3 has two second guide surfaces 31 respectively corresponding to the two first guide surfaces 141. When the first driving member 3 moves to the right and presses the mounting member 14, the second guide surfaces 31 slide and rub against the first guide surfaces 141, so that the horizontal movement of the first driving member 3 can be transmitted to the mounting member 14. At this time, the mounting member 14 can only move vertically under the structural restriction of the connector 12, thereby realizing the adjustment of the size of the roller 13 protruding from the connector 12.

[0054] The mounting component 14 is connected to the connector 12 via a reset structure 15. The reset direction of the reset structure 15 is the direction in which the roller 13 retracts into the connector 12, and the reset structure 15 can drive the mounting component 14 to move to reduce the size of the roller 13 protruding from the connector 12. Figure 3 As shown, the first driving member 3 can only achieve the purpose of the roller 13 protruding from the connector 12 by squeezing. The upper roller 13 can move downward by gravity, while the lower roller 13 will always protrude downward due to gravity. This situation will cause uneven force on the upper and lower sides of the connector 12. The lower roller 13 is easily damaged due to excessive pressure. At this time, the reset structure 15 is used to make both rollers 13 retract into the connector 12 to ensure the reliability of the rollers 13. It can also cooperate with the first driving member 3 to achieve bidirectional movement of the rollers 13. Preferably, the reset structure 15 is a spring, which is disposed between the mounting member 14 and the corresponding inner wall of the cavity 121. For example, the spring corresponding to the upper roller 13 is located between the mounting member 14 and the upper side wall of the cavity 121, and the spring corresponding to the lower roller 13 is located between the mounting member 14 and the lower side wall of the cavity 121. When the first driving member 3 presses the mounting member 14 and drives the roller 13 to move, the spring is compressed and accumulates elastic potential energy. When the first driving member 3 moves away from the mounting member 14, the spring releases elastic potential energy and drives the mounting member 14 to move, so that the roller 13 retracts into the connector 12, thereby resetting the roller 13.

[0055] The first driving component 3 includes a bolt and a wedge block. The end of the bolt is exposed on the surface of the drawer body 1. The wedge block is hinged to the end of the bolt located in the cavity 121. The bolt is threadedly engaged with the drawer body 1. When the bolt is rotated, the bolt moves along the length of the cavity 121, thereby driving the wedge block to move. The part of the wedge block facing the mounting component 14 forms a second guide surface 31. At this time, the movement of the bolt can be transmitted to the mounting component 14 through the wedge block, thereby driving the roller 13.

[0056] The drawer body 1 also includes a front panel 16, through which the user can pull out the drawer body 1. The front panel 16 can also be matched with the corresponding structure of the preset structure 100 to ensure the reliable position of the drawer body 1. The bolts of the first drive component 3 can be exposed on the surface of the drawer body 1 through the front panel 16. The user can directly operate the bolts at the door of the preset structure 100 to facilitate the adjustment of the position of the rollers 13 and to facilitate the quick pulling out of the drawer body 1, thereby improving the user experience.

[0057] To further enable the drawer assembly to be flexibly adjusted according to the size and shape of different ingredients, in addition to adjusting the installation position of the drawer body 1, the drawer assembly also includes a base plate 17 and an extension mechanism 4. The drawer body 1 forms a receiving cavity. The base plate 17 is connected to the drawer body 1 via an extension section 18, and the base plate 17 forms the bottom surface of the receiving cavity. The extension mechanism 4 is disposed on the drawer body 1, and the base plate 17 is connected to the extension mechanism 4. The extension mechanism 4 can move the base plate 17 away from or towards the drawer body 1, and the extension section 18 can always maintain a seal between the base plate 17 and the drawer body 1. By using the extension mechanism 4 to move the base plate 17, the volume of the receiving cavity can be adjusted, allowing the drawer body 1 to accommodate larger ingredients. Furthermore, the extension section 18 maintains a seal between the base plate 17 and the drawer body 1, ensuring that the receiving cavity only has an opening at the top for placing or retrieving items, thus guaranteeing the reliability of the drawer body 1 in storing ingredients. When the food items are large and need to be placed inside the drawer body 1, the installation position of the drawer body 1 can be moved upwards, that is, the position of the limiting screw 2 can be moved upwards. Then, the expansion mechanism 4 can be used to move the bottom plate 17 downwards to increase the volume of the accommodating cavity to accommodate the food items. At this time, the food items can be reliably preserved.

[0058] The upper end of the extension section 18 is sealed to the drawer body 1, and the lower end of the extension section 18 is sealed to the base plate 17. The distance between the upper end and the lower end of the extension section 18 is adjustable and can be adjusted as the base plate 17 moves to ensure the sealing effect of the extension section 18 between the base plate 17 and the drawer body 1.

[0059] In one embodiment, the extension section 18 includes a folding portion 181, which has a fully folded state and a fully unfolded state. The folding portion 181 can switch between these two states depending on the distance between the base plate 17 and the drawer body 1. When the folding portion 181 is in the folded state, the dimension of the extension section 18 in the height direction of the drawer body 1 is at its minimum. When the folding portion 181 is in the unfolded state, its dimension in the height direction of the drawer body 1 is at its maximum, and the base plate 17 is also at its maximum size. The folding portion 181 can switch arbitrarily between these two extreme states as the base plate 17 moves, ensuring reliable sealing between the extension section 18 and the base plate 17 and the drawer body 1.

[0060] The number of folding portions 181 is at least two, and all folding portions 181 are arranged side by side between the base plate 17 and the drawer body 1, with adjacent folding portions 181 being sealed together. Utilizing multiple folding portions 181 increases the maximum size of the extension section 18, thereby improving the adjustment range of the accommodating cavity volume, allowing the drawer assembly to accommodate more food sizes, improving the applicability of the drawer assembly and the user experience.

[0061] At least one folding slot is formed on the extension section 18, and each folding slot, together with a portion of the adjacent extension section 18, constitutes a folding part 181. By providing folding slots, the folding part 181 can be folded according to the position of the folding slot, ensuring the reliability of the switching between the folding part 181 and the unfolded state, avoiding undesigned deformation of the extension section 18 that could cause structural damage to the extension section 18, and ensuring the structural reliability of the drawer assembly.

[0062] The extension section 18 is made of a flexible material and can deform according to the distance between the base plate 17 and the drawer body 1. Utilizing the flexibility of the material, the reliability of the deformation and folding of the extension section 18 can be ensured. To achieve a reliable sealing connection between the base plate 17 and the drawer body 1, the extension section 18 can be configured as a ring structure or a square structure. The flexible material allows the extension section 18 to fold and deform based on the ring structure. Especially when the extension section 18 is a square structure, the deformation of the flexible material can also ensure reliable folding at the corners of the square structure.

[0063] Preferably, the flexible material is made of corrosion-resistant rubber, which can ensure the flexibility of the extension section 18 and also achieve the purpose of corrosion resistance and durability, ensuring the reliability of food preservation inside the drawer body 1.

[0064] Furthermore, a protective layer is also provided on the bottom plate 17 to improve the corrosion resistance and durability of the bottom plate 17, and to ensure the reliability of food preservation inside the drawer body 1.

[0065] The extension mechanism 4 includes a storage cylinder 41 and a telescopic rod 42. The telescopic rod 42 is movably disposed within the storage cylinder 41, and one end of the telescopic rod 42 protrudes from the storage cylinder 41 and connects to the base plate 17. The telescopic rod 42 can protrude from the storage cylinder 41, and the size of the protruding storage cylinder 41 can be adjusted, thereby driving the base plate 17. Figure 1 As shown, the storage tube 41 is integrally formed with the drawer body 1, and the axis of the storage tube 41 is a vertical straight line. The telescopic rod 42 can extend and retract in the vertical direction, thereby driving the bottom plate 17 to move up and down.

[0066] The number of extension mechanisms 4 can be set to multiple and distributed on different side walls of the drawer body 1, so that the base plate 17 can be connected and driven in different positions to ensure the reliability of the base plate 17.

[0067] The extension mechanism 4 further includes a second driving member 43, which is disposed on the storage cylinder 41 and can drive the telescopic rod 42 to move. The movement of the telescopic rod 42 driven by the second driving member 43 facilitates the adjustment of the movement of the base plate 17. Preferably, the second driving member 43 is a bolt, which is disposed on the top of the storage cylinder 41. The bolt is threaded into the storage cylinder 41 and is connected to the telescopic rod 42. When the bolt rotates, it moves vertically under the constraint of the thread, thereby driving the telescopic rod 42 to move vertically, thus achieving the purpose of moving the base plate 17.

[0068] A freezer including the drawer assembly described above.

[0069] The freezer is equipped with casters 5 at the bottom corner, and brakes are installed on the casters 5. The working state of the casters 5 can be switched by using the brakes to ensure the reliability of the freezer during movement.

[0070] The freezer is also equipped with a connecting seat 6, on which a wire 7 is fixedly connected. A limiting plate 8 is provided on the outer wall of the wire 7. The limiting plate 8 can prevent the wire 7 from being pulled excessively and ensure the service life of the wire 7.

[0071] The front side of the freezer has a handle 9 and a control panel. The handle 9 is equipped with a non-slip sleeve, allowing users to open and adjust the freezer directly from the front.

[0072] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
