Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to a refrigerator. Background Technology

[0002] A refrigerator is an electrical appliance that can maintain a constant low temperature, providing appropriate temperature and humidity conditions for fresh vegetables, fruits, meats, and other food items, thereby improving their preservation.

[0003] Refrigerator doors typically have shelves for storing small, frequently accessed items. In current refrigerators, these shelves are usually fixed to the door by ribs that snap onto the door liner. Because the ribs are fixed in position, the shelves can only be fixed in a preset position and cannot be freely adjusted according to the height of the stored food. Furthermore, the number of shelves cannot be increased due to the limited number of ribs on the door liner, which restricts the need for diverse compartmentation in the refrigerator and reduces the user experience. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide a refrigerator that improves the flexibility of using the shelf body.

[0005] The problems addressed in this application are not limited to those mentioned above, and other unmentioned problems can be clearly understood by those skilled in the art from the following description.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] A refrigerator includes a cabinet, a door, and a shelf assembly; the cabinet is configured to form a storage compartment; the door is connected to the cabinet to open or close the storage compartment; a door liner is provided on the side of the door facing the cabinet; the shelf assembly is disposed on the door liner, wherein the shelf assembly includes a fixing base, a shelf body, a snap-fit ​​member, and an elastic positioning member; the fixing base is fixed to the door liner, the fixing base includes a rack portion, the rack portion includes teeth distributed along the height direction of the door liner; the shelf body is detachably connected to the rack portion and can be connected between teeth of different heights in the rack portion; the snap-fit ​​member is connected to the door liner... The shelf body is rotatably connected. The snap-fit ​​component includes a positioning part located at one end of the snap-fit ​​component and snapping between two adjacent teeth of the rack component to fix the shelf body to the fixing seat. An elastic positioning member is connected to the shelf body and abuts against the side of the snap-fit ​​component facing the fixing seat, away from the positioning part. This restricts the positioning part to the rack component. When the snap-fit ​​component is pressed against the fixing seat, the elastic positioning member deforms towards the fixing seat, and the positioning part rotates away from the rack component, thereby unlocking the shelf body from the fixing seat. The rack component includes teeth distributed along the height direction of the shelf unit. The shelf body can be fixed to the rack component. By fixing the shelf body between teeth of different heights, the distance between adjacent shelf bodies can be adjusted, making it suitable for storing food of different heights. The elastic positioning member and the snap-fit ​​member have their ends away from the positioning part facing the fixed seat abut against each other. When the snap-fit ​​member is pressed towards the fixed seat, the elastic positioning member deforms towards the fixed seat. When the snap-fit ​​member is released, the rebound force of the elastic positioning member can push the end of the snap-fit ​​member away from the positioning part away from the fixed seat, thereby making the positioning part snap between the adjacent teeth, realizing the connection between the shelf body and the fixed seat. The operation is simple and the connection is stable.

[0008] In some embodiments of this application, the fixing seat includes a fixing part, which is distributed at least at both ends of the rack part and connected to the side of the rack part away from the shelf body, and fixed to the side wall of the door liner. The rack part ensures stable engagement between the shelf body and the rack part, and facilitates easy positioning when moving the shelf body, preventing shaking or displacement. Simultaneously, the fixing part not only strengthens the connection between the fixing seat and the side wall of the door liner but also ensures the stability of the fixing seat during long-term use. The cooperation between the rack part and the fixing part makes the entire shelf assembly more stable inside the refrigerator, improving safety and reliability.

[0009] In some embodiments of this application, the shelf body has mounting portions at both ends along its length. Each mounting portion includes two spaced-apart support ribs. A snap-fit ​​member and an elastic positioning member are respectively disposed between the two support ribs. Each support rib has a first through hole and a first connecting hole. The first through holes and the first connecting holes on the two support ribs are opposite to each other. The two ends of the elastic positioning member are respectively disposed in the first connecting holes of the two support ribs. The shelf assembly also includes a rotating shaft, which passes through the elastic positioning member and the snap-fit ​​member, and the two ends of the rotating shaft are respectively connected to the first through holes of the two support ribs. The mounting portions at both ends of the shelf body along its length fix the shelf body to a fixed base, ensuring the stability of the connection between the shelf body and the fixed base. Connecting the snap-fit ​​member and the elastic positioning member between the two support ribs via the rotating shaft results in a simple structure that ensures the balance of the shelf body.

[0010] In some embodiments of this application, the snap-fit ​​component includes a rotating part, a connecting part, and a positioning part arranged sequentially. The rotating part abuts against the elastic positioning member on the side facing the fixed seat. The connecting part is located between the rotating part and the positioning part, sleeved on the rotating shaft, and rotatably connected to the rotating shaft. The positioning part has a tooth on the side facing the fixed seat, and the tooth is adapted to the tooth profile of the rack portion. The rotating part and the positioning part are respectively located on opposite sides of the connecting part. The rotating part and the second positioning member can rotate around the connecting part. The elastic positioning member abuts against the side of the rotating part facing the positioning seat. The rotating part rotates away from the fixed seat, causing the positioning part to move closer to the first positioning part until the tooth is fixed on the first positioning part. Pressing the rotating part towards the fixed seat moves the positioning part away from the first positioning part, and the tooth disengages from the rack portion, allowing the shelf body to be removed from the fixed seat. The above structure is simple to operate, facilitates the installation of the shelf body, and provides high stability in the connection between the shelf body and the fixed seat.

[0011] In some embodiments of this application, the rotating part is provided with a pressing area, which protrudes from the side of the rotating part facing away from the fixed base. The pressing area protruding from the side of the rotating part facing away from the fixed base clearly indicates the pressing position of the snap-fit ​​component, facilitating operation.

[0012] In some embodiments of this application, the elastic positioning elements are symmetrically arranged, so that the rebound force of the elastic positioning elements can act more evenly on the snap-fit ​​elements, and the force between the protruding teeth of the snap-fit ​​elements and the tooth profile of the rack portion of the fixing seat is more uniform, thereby improving the connection stability between the shelf body and the fixing seat.

[0013] In some embodiments of this application, the elastic positioning member includes a first end, a first spiral portion, an abutment portion, a second spiral portion, and a second end, arranged sequentially. The first end and the second end are respectively disposed in the first connecting holes on the two supporting ribs. The first spiral portion and the second spiral portion are sleeved on the rotating shaft. The snap-fit ​​member is disposed between the first spiral portion and the second spiral portion. The abutment portion abuts against the side of the rotating portion facing the fixed seat. The first end and the second end are respectively fixed in the first connecting holes of the two supporting ribs to achieve positioning of the elastic positioning member and the shelf body, so that when the abutment portion is squeezed, the elastic positioning member will not shift, generating elastic deformation and accumulating elastic force to push the rotating portion to rotate away from the fixed seat when resetting, thereby causing the protruding teeth to snap onto the rack portion. The first spiral portion and the second spiral portion are disposed on both sides of the abutment portion and sleeved on the rotating shaft, so that the elastic positioning member can be stably connected to the rotating shaft when deformed, and can stably push the snap-fit ​​member to rotate when the elastic positioning member is reset.

[0014] In some embodiments of this application, one end of the rotating shaft is provided with a limiting flange, and the other end of the rotating shaft is provided with a limiting buckle. The limiting flange and the limiting buckle are located outside the first through hole. The limiting buckle has a groove portion and multiple buckle portions, which are separated by the groove portion. The limiting flange at one end of the rotating shaft and the limiting buckle at the other end limit the rotating shaft to the two support ribs, preventing the rotating shaft from loosening. The groove portion separates the multiple buckle portions, creating a gap between adjacent buckle portions. When the outer periphery of the limiting buckle is compressed, the buckle portions deform towards the groove portion, thereby reducing the radial area of ​​the limiting buckle and ensuring that the limiting buckle can pass through the first through hole. When the limiting buckle passes through the first through hole, the limiting buckle is no longer compressed, the buckle portions reset, and the limiting buckle is located outside the first through hole, thus achieving the positioning of the rotating shaft.

[0015] In some embodiments of this application, the outer surface of the limiting buckle is configured as a guide surface. The guide surface facilitates the passage of the rotating shaft through the first through hole.

[0016] In some embodiments of this application, the door liner is provided with a second through hole. Two second through holes are provided, spaced apart at both ends along the length of the shelf body. The rack portion passes through the second through hole and protrudes from the side of the door liner facing the shelf body. The fixing portion, facing the rack portion, is fixed to the side of the door liner facing away from the cabinet body. A fixing seat passes through the second through hole from the side of the door liner facing away from the cabinet body and is fixed to the side wall of the door liner. The fixing portion of the fixing seat, facing the rack portion, is connected to the side wall of the door liner. The shelf body is connected to the fixing seat, and the fixing portion is more tightly fixed to the side wall of the door liner. Furthermore, the foam material between the cabinet door shell and the door liner can hold the fixing portion in place, ensuring a reliable connection between the fixing seat and the door liner.

[0017] Beneficial effects:

[0018] According to at least one embodiment of this application, by providing a rack portion on the fixed base, with the teeth of the rack portion distributed along the height direction of the door liner, and the shelf body connected to the rack portion, the relative position of the shelf body and the rack portion can be adjusted according to usage requirements, thereby improving the flexibility of the shelf body and the applicability of the refrigerator.

[0019] According to at least one embodiment of this application, by setting a snap-fit ​​member and an elastic positioning member to connect to the shelf body, and connecting the shelf body to the fixed base, the operation is simple and the user experience is improved.

[0020] The effects of this application are not limited to those mentioned above, and those skilled in the art can clearly understand other effects not mentioned from the description in the claims. Attached Figure Description

[0048] A duct 122 can be installed at the same height on either the left or right side wall.

[0049] Multiple gallbladder ribs 122 can be installed at the same height on the left or right side wall, along the front and back of the gallbladder rib 122.

[0050] Figure 3 This is a structural schematic diagram of the cabinet door from a first-person perspective, provided in this application. Figure 4 This is a structural schematic diagram of the box door from a second perspective, provided in this application.

[0051] like Figure 3 and Figure 4 As shown, the refrigerator may include a door 200. The door 200 is connected to the body 100. The door 200 may be hinged to the side of the body 100 where the access opening 123 is provided, to open or close the liner 120, thereby insulating the liner 120 from the outside.

[0052] The refrigerator door 200 includes a door liner 1, which is located on the side of the door 200 facing the door liner 120. A shelf assembly 2 can be installed on the door liner 120. The shelf assembly 2 can be used to place small or frequently accessed food items, such as bottled, bagged, or canned beverages, condiments, eggs, etc. The shelf assembly 2 increases the refrigerator's storage space, making food storage more flexible and convenient, with clearer partitioning, thus meeting the diverse needs of users in daily refrigerator use.

[0053] Figure 5 for Figure 4 A cross-sectional view along the BB direction. Figure 6 for Figure 5 Enlarged view of region A. Figure 7 This is a structural schematic diagram of the shelving assembly provided in this application in its first usage state. Figure 8 This is a structural schematic diagram of the shelving assembly provided in this application under a second usage state.

[0054] like Figures 3 to 6As shown, the shelf assembly 2 may include a fixing base 21, a shelf body 22, a snap-fit ​​member 23, and an elastic positioning member 24. The fixing base 21 is fixed to the door frame 1 and extends along the height direction of the door frame 1. The fixing base 21 includes a rack portion 211, which includes teeth distributed along the height direction of the door frame 1. A positioning space for fixing the shelf body 22 is formed between adjacent teeth. The shelf body 22 is detachably connected to the fixing base 21 and can be connected between teeth of different heights on the rack portion 211. This allows storage spaces of different heights to be formed between adjacent shelf bodies 22, or the number of shelf bodies 22 can be increased or decreased according to usage needs to accommodate food items of different heights.

[0055] Figure 7 and Figure 8 This is a structural diagram illustrating two different usage states of shelf assembly 2. (See diagram below.) Figure 7 As shown, the door 200 has three shelf bodies 22, and the distance between the highest shelf body 22 and the middle shelf body 22 is relatively large, which can accommodate taller bottled and canned food items. Figure 8 As shown, four shelf components 2 are provided on the door 200 to accommodate more food items.

[0056] like Figure 6 As shown, the snap-fit ​​member 23 is rotatably connected to the shelf body 22, allowing the snap-fit ​​member 23 to open or engage with the rack portion 211 in the rotational direction. The snap-fit ​​member 23 includes a positioning portion 233. The positioning portion 233 is located at one end of the snap-fit ​​member 23 and can engage between two adjacent teeth of the rack portion 211 to fix the shelf body 22 to the fixing base 21. The elastic positioning member 24 is connected to the shelf body 22 and abuts against the side of the snap-fit ​​member 23 away from the positioning portion 233 facing the fixing base 21, so that the positioning portion 233 is limited to the rack portion 211, and the shelf body 22 is stably connected to the fixing base 21. When the end of the latching member 23 away from the positioning part 233 is pressed towards the fixed seat 21, the elastic positioning member 24 deforms toward the fixed seat 21, and the positioning part 233 rotates away from the rack part 211, increasing the distance between the positioning part 233 and the rack part 211, thereby unlocking the shelf body 22 from the fixed seat 21. At this time, the shelf body 22 can be removed from the fixed seat 21.

[0057] Figure 9 This is a structural schematic diagram of the box door provided in this application from a third-person perspective.

[0058] like Figure 9As shown, the door frame 1 is provided with a second through hole 11, which extends along the height direction of the door frame 1. A rack portion 211 passes through the second through hole 11 and protrudes from the side of the door frame 1 facing the shelf body 22. The rack portion 211 protrudes towards the door shelf body 22, which facilitates the connection between the shelf body 22 and the rack portion 211.

[0059] In some embodiments, the radial cross-section of the second through hole 11 is rectangular. The rectangular shape of the second through hole 11 is adapted to the shape of the rack portion 211, ensuring the connection reliability of the rack portion 211.

[0060] In some embodiments, the door frame 1 is provided with two second through holes 11, which are spaced apart along the length of the door frame 1. Each second through hole 11 is connected to a fixing seat 21, and the two ends of the shelf body 22 along the length are respectively fixed to the two fixing seats 21.

[0061] like Figure 6 and 9 As shown, in some embodiments, the fixing base 21 includes a fixing part 212. The fixing part 212 is distributed at least at both ends of the rack part 211 and is connected to the side of the rack part 211 away from the shelf body 22. The fixing part 212 is fixed to the side wall of the door liner 1. The side of the fixing part 212 facing the rack part 211 is fixed to the side of the door liner 1 facing away from the box body 100. There is a filling space between the outer shell of the box door 200 and the door liner 1, which can be filled with foam material. The foam material presses against the fixing part 212, making the connection between the fixing part 212 and the side wall of the door liner 1 more reliable.

[0062] In some embodiments, the fixing part 212 is provided on the circumferential outer side of the rack part 211. The fixing part 212 is provided on the outer periphery of the rack part 211, so that the fixing seat 21 can be more evenly and stably connected to the door shell 1, thereby improving the reliability of the connection between the fixing seat 21 and the door shell 1.

[0063] In some embodiments, the shelf assembly 2 includes an adhesive member 26. The adhesive member 26 is disposed between the fixing part 212 and the door frame 1, enabling quick pre-positioning between the fixing seat 21 and the door frame 1. The adhesive member 26 can be made of double-sided adhesive sponge, which is convenient to use and can be connected to both the fixing part 212 and the door frame 1 simultaneously. In other embodiments, the adhesive member 26 can also be made of other adhesive materials.

[0064] Figure 10 A schematic diagram of the structure of the shelving assembly provided in this application.

[0065] like Figure 3 , Figure 6 and Figure 10As shown, in some embodiments, the shelf body 22 has mounting portions 221 at both ends along its length. The mounting portions 221 of the shelf body 22 are fixed to the fixing base 21 by snap-fit ​​members 23 and elastic positioning members 24.

[0066] In some embodiments, the mounting portion 221 includes two spaced-apart support ribs 2211, with a snap-fit ​​member 23 and an elastic positioning member 24 respectively disposed between the two support ribs 2211. This ensures a stable and reliable connection between the shelf body 22 and the fixed base 21.

[0067] In some embodiments, the shelf assembly 2 includes a rotating shaft 25. The rotating shaft 25 passes through two support ribs 2211 of the mounting portion 221. Each support rib 2211 has a first through hole 2212, and the first through holes 2212 on the two support ribs 2211 are arranged opposite to each other. The rotating shaft 25 passes through the first through holes 2212 on the two support ribs 2211.

[0068] Figure 11 This is a schematic diagram of the connection structure between the snap-fit ​​component, the elastic positioning component, and the rotating shaft provided in this application. Figure 12 This is a schematic diagram of the snap-fit ​​connector provided in this application snapping into the fixing base. Figure 13 This is a schematic diagram of the structure of the snap-fit ​​release fixing seat provided in this application.

[0069] like Figures 10 to 13 As shown, in some embodiments, the snap-fit ​​member 23 includes a rotating part 231, a connecting part 232, and a positioning part 233. The rotating part 231 and the positioning part 233 are respectively disposed on both sides of the connecting part 232. The rotating part 231 is disposed radially above the connecting part 232, and the positioning part 233 is disposed radially below the connecting part 232. The rotating shaft 25 passes through the connecting part 232 and can be rotatably connected to the connecting part 232, ensuring that the rotating part 231 and the positioning part 233 can rotate around the rotating shaft 25. The side of the rotating part 231 facing the fixed seat 21 abuts against the elastic positioning member 24. That is, when the elastic positioning member 24 pushes the rotating part 231 toward the shelf body 22, the positioning part 233 gradually approaches the rack part 211 of the fixed seat 21 until it is positioned by the rack part 211. When the rotating part 231 is pressed toward the fixed seat 21, the positioning part 233 moves away from the fixed seat 21, causing the positioning part 233 to disengage from the rack part 211, thereby unlocking the snap-fit ​​part 23 from the fixed seat 21. At this time, the shelf assembly 2 can be removed from the door frame 1.

[0070] The positioning part 233 has a protruding tooth 2331 on the side facing the fixing base 21. The protruding tooth 2331 is adapted to the tooth profile of the rack part 211, so that the protruding tooth 2331 can be engaged between two adjacent teeth, allowing the shelf body 22 to be fixed at any height of the fixing base 21, improving the flexibility of use of the shelf body 22. The shape of the tooth profile of the rack part 211 is consistent with the rotation trajectory of the protruding tooth 2331, avoiding motion interference between the rack part 211 and the engaging member 23.

[0071] like Figure 10 As shown, the rotating part 231 is provided with a pressing area 2311. The pressing area 2311 is shown on the side of the rotating part 231 facing away from the fixed base 21. The pressing area 2311 protrudes from the rotating part 231 and can clearly indicate the pressing position of the snap-fit ​​member 23, which is convenient for operation.

[0072] In some embodiments, the pressing area 2311 is located in the middle of the upper end of the rotating part 231, making operation easier.

[0073] In some embodiments, the pressing area 2311 is projected onto the rotating part 231 in a circular shape with smooth edges, providing a good pressing feel. It is understood that in other embodiments, the pressing area 2311 may also be set as an ellipse or other shapes.

[0074] like Figure 11 As shown, one end of the rotating shaft 25 is provided with a limiting flange 251. The diameter of the limiting flange 251 is larger than the diameter of the first through hole 2212. The other end of the rotating shaft 25 is provided with a limiting buckle 252. The limiting flange 251 and the limiting buckle 252 are positioned outside the first through hole 2212. The above arrangement ensures that the rotating shaft 25 can be limited within the support rib 2211, preventing the rotating shaft 25 from falling out of the first through hole 2212 and ensuring the reliability of the connection between the shelf assembly 2 and the door frame 1.

[0075] In some implementations, the limiting buckle 252 has a groove portion 2521 and multiple buckle portions 2522. The buckle portions 2522 are separated by the groove portion 2521. The maximum diameter of the limiting buckle 252 in its extended state is greater than the diameter of the first through hole 2212, and the maximum diameter of the limiting buckle 252 in its contracted state (when the outer periphery is compressed) is less than the diameter of the first through hole 2212. Thus, when the outer side of the buckle portion 2522 is compressed, the buckle portion 2522 can deform toward the groove portion 2521, thereby reducing the diameter of the limiting buckle 252 and ensuring that the limiting buckle 252 can pass through the first through hole 2212. Furthermore, after the limiting buckle 252 passes through the first through hole 2212, the buckle portion 2522 returns to its original position, thereby limiting the rotation shaft 25.

[0076] Furthermore, the outer surface of the limiting buckle 252 is set as a guide surface 25221 to facilitate the rotation shaft 25 passing through the first through hole 2212.

[0077] like Figure 10 As shown, in some embodiments, the support rib 2211 is provided with a first connecting hole 2213, and the first connecting holes 2213 on the two support ribs 2211 are arranged opposite to each other. The elastic positioning member 24 is sleeved on the rotating shaft 25, and both ends of the elastic positioning member 24 are respectively fixed in the first connecting holes 2213 of the two support ribs 2211, ensuring that the elastic positioning member 24 will not shift when it abuts against the snap-fit ​​member 23, thereby ensuring the connection stability between the shelf body 22 and the fixed seat 21. In addition, when the snap-fit ​​member 23 is pressed towards the fixed seat 21, the elastic positioning member 24 will not shift, ensuring that the elastic positioning member 24 generates effective deformation and accumulates the elastic force for reset.

[0078] In some embodiments, the elastic positioning members 24 are symmetrically arranged. The symmetrical structure allows the rebound force of the elastic positioning members 24 to act more evenly on the snap-fit ​​member 23, making the force between the protrusions 2331 of the snap-fit ​​member 23 and the tooth profile of the rack portion 211 of the fixing seat 21 more even, thereby improving the connection stability between the shelf body 22 and the fixing seat 21.

[0079] like Figure 11 As shown, the elastic positioning member 24 includes a first end 241, a first spiral portion 242, an abutment portion 243, a second spiral portion 244, and a second end 245 arranged sequentially. The first end 241 and the second end 245 are respectively disposed in the first connecting holes 2213 of the two support ribs 2211 of the mounting portion 221, so as to realize the positioning of the elastic positioning member 24 and the shelf body 22, so that when the abutment portion 243 is squeezed, the elastic point will not shift, and elastic deformation will be generated and elastic force will be accumulated, which is used to push the rotating portion 231 to rotate away from the fixed base 21 when resetting.

[0080] The first helical portion 242 and the second helical portion 244 are sleeved on the rotating shaft 25. The snap-fit ​​member 23 is disposed between the first helical portion 242 and the second helical portion 244. The abutting portion 243 abuts against the side of the rotating portion 231 facing the fixed seat 21. The first helical portion 242 and the second helical portion 244 are respectively disposed on both sides of the abutting portion 243 and sleeved on the rotating shaft 25, ensuring that when the elastic positioning member 24 deforms, it can be stably connected to the rotating shaft 25, and when the elastic positioning member 24 returns to its original position, it can stably push the snap-fit ​​member 23 to rotate.

[0081] When installing the shelf assembly 2, first fix the first end 241 and the second end 245 of the elastic positioning member 24 into the first connecting hole 2213 of the mounting part 221 of the shelf body 22 to complete the assembly of the elastic positioning member 24 and the shelf body 22; then pass one end of the rotating shaft 25 with the limit buckle 252 through the first through hole 2212 of one of the support ribs 2211 of the mounting part 221, and then pass through the first spiral part 242, the snap-fit ​​member 23, and the second spiral part 244 of the positioning member in sequence, and finally pass through the first through hole 2212 of the other support rib 2211 of the mounting part 221, and then fix the connected snap-fit ​​member 23, elastic positioning member 24 and shelf body 22 to the fixing base 21.

[0082] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and concept of this application, and all such substitutions or changes should fall within the protection scope of the appended claims.
