Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to stirring heads, stirring components, stirring containers and food processing machines. Background Technology

[0002] With the widespread use and technological advancements in refrigeration equipment, the design of its internal drawer components faces new challenges while pursuing high efficiency and energy saving. Currently, drawers in refrigeration equipment (such as refrigerators and freezers) typically employ highly sealed structures to reduce cold air leakage and thus lower energy consumption. However, this design results in a sealed space between the drawer and the inner wall of the equipment when closed. When the refrigeration system is running, the internal air contracts due to cooling, causing a decrease in air pressure and creating a negative pressure state. At this time, the external atmospheric pressure is much higher than the internal pressure, resulting in a greater suction force on the drawer. Users need to apply considerable pulling force to open it, especially when the drawer is large or has an excessively strong seal, making operation more difficult and severely impacting the user experience.

[0046] With the popularization and technological development of refrigeration equipment, the design of its internal drawer assembly 10 faces new challenges while pursuing high efficiency and energy saving. Currently, the drawers of refrigeration equipment (such as refrigerators and freezers) typically adopt a highly airtight structure to reduce cold air leakage, thereby reducing energy consumption. However, this design results in a sealed space between the drawer and the inner wall of the equipment when closed. When the refrigeration system is running, the internal air contracts due to cooling, reducing the air pressure and creating a negative pressure state. At this time, the external atmospheric pressure is much higher than the internal pressure, causing the drawer to be subject to a large suction force. Users need to apply a lot of pulling force to open it, especially when the drawer area is large or the airtightness is too strong, making operation more difficult and seriously affecting the user experience.

[0047] Based on this, this application proposes a drawer assembly 10, in which the user only needs a small amount of force to rotate the front panel 100 to make the receiving cavity 201 connected to the outside for pressure relief, thereby reducing the difficulty of opening the drawer.

[0048] The drawer assembly 10 according to the embodiments of this application includes: a front panel 100, a drawer body 200, and a connecting assembly 300. The drawer body 200 has a receiving cavity 201 inside. The connecting assembly 300 includes a fixing seat 310 and a bracket 320. The fixing seat 310 is connected to the front panel 100, and the bracket 320 is connected to the drawer body 200. The fixing seat 310 is rotatably connected to the bracket 320.

[0049] The drawer assembly 10 has a locked state and a depressurized state. In the locked state, the front panel 100 and the drawer body 200 maintain a fixed angle to ensure the drawer's airtightness. In one possible embodiment, the front panel 100 of the drawer body 200 in the closed position abuts against the opening 22 of the refrigeration device, so that the receiving cavity 201 is in a sealed state. In the depressurized state, the fixing base 310 rotates relative to the bracket 320, and the front panel 100 rotates relative to the drawer body 200 by a preset angle, so that the receiving cavity 201 of the drawer body 200 in the closed position is connected to the outside. In this way, when a negative pressure is formed inside the drawer, external air can enter the receiving cavity 201 through this channel, balancing the internal and external pressures and reducing the suction force on the drawer.

[0050] According to the embodiment of this application, in the drawer assembly 10, the fixing seat 310 of the connecting assembly 300 can rotate relative to the bracket 320, thereby causing the front panel 100 to rotate relative to the drawer body 200. The user only needs to use a small amount of force to rotate the front panel 100 to allow the receiving cavity 201 to connect to the outside and release pressure, reducing the difficulty of opening the drawer. This not only improves the user experience but also maintains the high sealing performance of the drawer.

[0051] It should be noted that the opening 22 mentioned here can be understood as the opening 22 of the refrigeration equipment facing the user. The drawer slides through the opening 22 into the cavity 21 inside the cabinet 20. When the drawer assembly 10 is closed, the front panel 100 will cover the opening 22.

[0052] According to one embodiment of this application, the connecting assembly 300 includes a pivot 330, the fixed base 310 is rotatably connected to the bracket 320 via the pivot 330, the front panel 100 is provided with a handle side, and the pivot 330 is located on the side of the fixed base 310 away from the handle side.

[0053] The fixed base 310 is rotatably connected to the bracket 320 via a pivot 330. The front panel 100 has a handle side, which may include a handle rod or handle groove for the user to pull open the drawer. The pivot 330 is located on the side of the fixed base 310 away from the handle side. When the user needs to pull open the drawer, they naturally grip the handle side and apply pulling force. The pivot 330's location away from the handle side allows the front panel 100 to rotate around the pivot 330 when subjected to pulling force, thus easily achieving a pressure relief state and reducing the difficulty of opening the drawer.

[0054] According to one embodiment of this application, the connecting component 300 includes a limiting mechanism 340, which is used to limit the rotation angle of the fixed base 310 relative to the bracket 320, and the maximum value of the rotation angle is the preset angle.

[0055] The limiting mechanism 340 is used to limit the rotation angle of the fixed base 310 relative to the bracket 320. During the use of the drawer assembly 10, the front panel 100 can be kept within a specific angle range when rotating to ensure the drawer's sealing and ease of use.

[0056] The limiting mechanism 340, through a precise control mechanism, limits the maximum rotation angle of the fixed base 310 relative to the bracket 320. This maximum rotation angle is the preset angle. When the front panel 100 is subjected to external force and begins to rotate, the limiting mechanism 340 ensures that its rotation angle does not exceed this preset value, thus preventing the drawer from becoming difficult to open due to excessive rotation. This design not only ensures the stability of the drawer assembly 10 under pressure relief but also allows users to more easily control the rotation of the front panel 100 during use, further enhancing the user experience.

[0057] According to one embodiment of this application, the limiting mechanism 340 includes a first slider 341, a second slider 342, and a limiting shaft 343. The first slider 341 is fixedly connected to the fixed base 310, and the second slider 342 is fixedly connected to the bracket 320. The first slider 341 is provided with a first through hole 344, and the second slider 342 is provided with a second through hole 345. The limiting shaft 343 passes through the first through hole 344 and the second through hole 345, and the opening area of ​​the first through hole 344 and the second through hole 345 is larger than the cross-sectional area of ​​the limiting shaft 343 passing through the first through hole 344 and the second through hole 345.

[0058] The first slider 341 is fixedly connected to the fixed base 310, while the second slider 342 is fixedly connected to the bracket 320. The first slider 341 and the second slider 342 can move in sync with the movement of the fixed base 310 and the bracket 320, respectively. The first slider 341 has a first through hole 344, and the second slider 342 has a second through hole 345. The first through hole 344 and the second through hole 345 are used to accommodate the limiting shaft 343. The opening areas of the first through hole 344 and the second through hole 345 are designed to be larger than the cross-sectional area through which the limiting shaft 343 passes, allowing the limiting shaft 343 to move within the first through hole 344 and the second through hole 345. This allows the fixed base 310 to move freely within a preset angle when rotating relative to the bracket 320. When the rotation angle reaches the preset value, the limiting shaft 343 will contact the edge of the through hole, thereby preventing the fixed base 310 from continuing to rotate.

[0059] According to one embodiment of this application, the preset angle is 0.2° to 0.5°. Setting the preset angle within the range of 0.2° to 0.5° ensures that the front panel 100 can sufficiently open the communication channel between the receiving cavity 201 and the outside when rotating, achieving effective pressure relief, while avoiding damage to the sealing or instability of the drawer structure caused by excessive rotation angle.

[0060] According to one embodiment of this application, the connecting assembly 300 includes an elastic element 350, which is used to provide an elastic force to the fixing seat 310 to maintain a fixed angle with the bracket 320.

[0061] Specifically, when the drawer is closed, the elastic element 350 is in a compressed or stretched state, storing a certain amount of mechanical energy. This energy causes the fixed base 310 to tend to maintain a relatively fixed angle with the bracket 320, and it can quickly return to its original position even if it is disturbed by a certain external force. In this way, the sealing between the front panel 100 and the drawer body 200 is effectively guaranteed.

[0062] After the drawer is closed, it can automatically reset under the elastic action of the elastic element 350, so that the drawer assembly 10 is in a locked state without external force. In one embodiment, the front door panel is also provided with a sealing strip 30, and the elastic element 350 can make the sealing strip 30 abut against the periphery of the opening 22 of the box body 20 to achieve better sealing.

[0063] In one embodiment, the elastic element 350 is a torsion spring, with the first end of the torsion spring fixedly connected to the fixed base 310 and the second end of the torsion spring fixedly connected to the bracket 320.

[0064] In one embodiment, the elastic element 350 is a torsion spring, which is sleeved on the rotating shaft 330 and its two ends abut against the fixed seat 310 and the bracket 320 respectively.

[0065] According to one embodiment of this application, the number of connecting components 300 is two, one of which is located on the left side of the drawer body 200, and the other is located on the right side of the drawer body 200.

[0066] The left connecting component 300 connects to the left side of the drawer body 200, providing stable support and a rotation axis for the left fixed base 310. Similarly, the right connecting component 300 connects to the right side of the drawer body 200, providing the same support and rotation function for the right fixed base 310. The two connecting components 300 work together to ensure the smoothness and stability of the drawer during opening and closing.

[0067] A refrigeration device according to a second aspect embodiment of the present application includes: a housing 20 and the drawer assembly 10 described above. The housing 20 has a cavity 21 and an opening 22 inside, and the drawer assembly 10 is slidably connected to the cavity 21.

[0068] The refrigeration device provided in the second aspect of this application incorporates the drawer assembly 10 described above, and is intended to improve the user's experience of pulling out the drawer assembly 10.

[0069] The cabinet 20 is the main structural part of the refrigeration equipment. It has an internal cavity 21 for storing food or other items that need to be refrigerated / frozen. The cabinet 20 has an opening 22 that communicates with the cavity 21, allowing the user to slide the drawer assembly 10 into or out of the cavity 21.

[0070] The drawer assembly 10 is slidably connected to the cavity 21 of the cabinet 20. The connecting assembly 300 ensures the stability and smoothness of the drawer assembly 10 during the sliding process, while providing a slight rotation function of the front panel 100 relative to the drawer body 200 to facilitate pressure relief and opening.

[0071] In one embodiment, when a user needs to store or retrieve an item, they simply pull the front panel 100 of the drawer assembly 10 gently. The pivot 330 in the connecting assembly 300 allows the front panel 100 to rotate slightly relative to the drawer body 200 when subjected to external force, thus connecting the receiving cavity 201 to the outside, thereby balancing internal and external pressure, reducing the suction force on the drawer assembly 10, and making the drawer assembly 10 easier to open. The limiting mechanism 340 ensures that the rotation angle of the front panel 100 is controlled within a preset range. After depressurization, the user can slide the drawer assembly 10 within the cavity 21 of the cabinet 20 with very little force. During this process, after the user's hand leaves the handle of the front panel 100, the drawer assembly 10 is free from external force, and the elastic element 350 provides the fixing seat 310 with an elastic force that maintains a fixed angle with the bracket 320, thereby restoring the locked state. After the user finishes using the drawer assembly 10, the drawer assembly 10 can be pushed back at least partially into the cavity 21, and the front panel 100 abuts against the opening 22 of the cabinet 20, ensuring the sealing of the receiving cavity 201.

[0072] According to one embodiment of this application, the front panel 100 is provided with a sealing strip 30 on the side facing the drawer body 200. In the locked state, the sealing strip 30 abuts against the periphery of the opening 22 to achieve a seal.

[0073] Understandably, the sealing strip 30 is made of a soft and elastic material, such as rubber or silicone, which can fit tightly against the periphery of the opening 22 of the cabinet 20. When the drawer assembly 10 is located in the cavity 21 and is in the locked state, the front panel 100 fits tightly against the opening 22 of the cabinet 20, at which point the sealing strip 30 abuts against the periphery of the opening 22, forming an effective sealing barrier.

[0074] According to one embodiment of this application, a slide rail assembly 40 is included. The slide rail assembly 40 includes a slide rail body 41 and a slide rail component 42. The slide rail body 41 is slidably connected to the slide rail component 42. The slide rail body 41 is connected to the bracket 320. The slide rail component 42 is connected to the interior of the housing 20.

[0075] The slide rail body 41 is slidably connected to the slide rail component 42, forming a sliding mechanism that allows the drawer assembly 10 to slide smoothly inside the cabinet 20. The slide rail body 41 is connected to the bracket 320 of the drawer assembly 10, providing stable support and guidance for the drawer assembly 10. The slide rail component 42 is connected inside the cabinet 20 and fixed to the side wall or bottom of the cabinet 20, providing a sliding track for the slide rail body 41.

[0076] It should be noted that, in addition to being located on the side wall of the drawer body 200, the slide rail assembly 40 can also be located on the bottom of the drawer body 200, which will not be elaborated here.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should be covered within the scope of the claims of this application.
