[0002] With continuous technological advancements, refrigerators on the market are achieving increasingly higher capacity utilization rates. However, to further improve this efficiency, the foam layer of the refrigerator body is becoming thinner. Simultaneously, with the growing popularity of built-in refrigerators, technologies such as dual-axis hinges are being used to retract the door when opened, preventing collisions with cabinets. When the foam layer of a built-in refrigerator is thin, the door may extend beyond the foam layer, hindering the removal of drawers and shelves. While the common solution for difficult drawer removal is to narrow the drawers and cover the narrowed portion with decorative covers, the problem of difficult shelf removal remains largely unresolved.

[0048] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0049] With the increasing popularity of built-in refrigerators and thin-walled foam shelves, the problem of difficult-to-remove shelves is becoming more and more apparent. For example... Figure 1 , Figure 2 As shown, in existing built-in refrigerator products, even when the refrigerator door is opened to its maximum angle, the shelves will collide with the door and cannot be removed when they are pulled out horizontally. This makes it extremely inconvenient for users to disassemble the shelves when they want to clean them.

[0050] Based on this, the present invention proposes a refrigerator shelf structure and a refrigerator, ensuring that users can easily disassemble the shelves when needed.

[0051] It should be noted that this utility model mainly improves the refrigerator shelf structure. The following will first briefly introduce the overall structure of the refrigerator, and then elaborate on the refrigerator shelf structure and its control method.

[0052] like Figure 3 and Figure 4 As shown, the refrigerator provided by this utility model includes not only a cabinet 11 with compartments and doors 12 that can be opened and closed on the cabinet 11, but also a refrigerator shelf structure. In practical applications, the product form of the refrigerator will vary depending on the number of doors 12, including single-door refrigerators, side-by-side refrigerators, and other multi-door refrigerators. Furthermore, the cabinet 11 is mainly composed of an outer shell, compartments (defined by compartment liners 13), and a foam layer, wherein the foam layer is located between the compartment liners 13 and the outer shell, mainly serving an insulation function. The compartments can be divided into refrigerator compartments and freezer compartments. In addition, a control panel can be installed on the door 12 to facilitate users issuing specific commands. For example, when a user needs to clean the shelf 21, they can press the cleaning button on the control panel.

[0053] like Figure 3 , Figure 4 and Figure 5 As shown, the refrigerator shelf structure provided by this utility model includes a shelf 21 and a flipping mechanism 22. The shelf 21 is detachably installed in the compartment for placing items; the flipping mechanism 22 is installed on the compartment liner 13 and connected to the shelf 21, for driving the shelf 21 to flip so that the shelf 21 can switch between a horizontal state and an inclined state.

[0054] This invention, by adding a flipping mechanism 22, enables the shelf 21 to flexibly switch between a horizontal and an inclined state. When the shelf 21 is in a horizontal state, it is convenient for users to place items; while when the shelf 21 is in an inclined state, it is convenient for users to disassemble. This design effectively avoids the shelf 21 colliding with the door 12 when it is pulled out, thus ensuring smooth disassembly and effectively improving the user experience.

[0055] It should be noted that the number of flipping mechanisms 22 can be flexibly set according to actual needs. For example, for a single-door refrigerator, one flipping mechanism 22 can be provided for each shelf 21. In this case, the shelf 21 can be fixed on the side away from the hinge end of the door 12, i.e., it cannot be flipped, while the side closer to the hinge end of the door 12 is driven to flip by the flipping mechanism 22, thus ensuring that it will not collide with the door 12 when the user pulls out the shelf 21. Of course, in the design of a single-door refrigerator, two flipping mechanisms 22 can also be provided for each shelf 21, so that both sides of the shelf 21 can be flipped by the flipping mechanism 22, making the disassembly of the shelf 21 more convenient. For another example, for a side-by-side refrigerator, one flipping mechanism 22 can be set on each side of each shelf 21, so that both sides of the shelf 21 can be flipped by the flipping mechanism 22, thus greatly facilitating the disassembly of the shelf 21.

[0056] For ease of explanation, the following will first take a single flipping mechanism 22 as an example to explain the structure of the flipping mechanism 22 in detail.

[0057] like Figure 4 , Figure 5 and Figure 6 As shown, the flipping mechanism 22 mainly includes a housing 221, a drive assembly 222, and a connecting assembly 223. The housing 221 is fixedly mounted on the compartment liner 13 and located within the foam layer. The housing 221 has a sliding groove 2211. The drive assembly 222 is fixedly mounted inside the housing 221. The connecting assembly 223 connects the drive assembly 222 and the shelf 21. Under the action of the drive assembly 222, the connecting assembly 223 slides along the sliding groove 2211, thereby causing the shelf 21 to flip.

[0058] This invention uses a drive assembly 222 to drive a connecting assembly 223 to move along the slide groove 2211 of the sleeve 221, and uses the connecting assembly 223 to flip the shelf 21. This design not only allows for angle adjustment of the shelf 21, but also improves the stability of the shelf 21 during the flipping process.

[0059] like Figure 5 , Figure 7 and Figure 8 As shown, the connecting assembly 223 includes a connecting rod component and a snap-fit ​​component.

[0060] The connecting rod assembly includes a connecting rod body and a sliding shaft 2231, a mounting shaft 2232 and a transmission shaft 2233 respectively disposed on the connecting rod body. The sliding shaft 2231 passes through the sliding groove 2211 and the transmission shaft 2233 is connected to the drive assembly 222.

[0061] The snap-fit ​​component includes a snap-fit ​​body and a mounting fitting part 2234 and a limiting groove 2235 respectively provided on the snap-fit ​​body. The mounting fitting part 2234 is sleeved on the outside of the mounting shaft 2232, and the limiting groove 2235 is snap-fitted to the shelf 21. In practical applications, the mounting fitting part 2234 is provided with a shaft hole 22340 for the mounting shaft 2232 to pass through. Two mounting fitting parts 2234 can be arranged at intervals on the snap-fit ​​body, and these two mounting fitting parts 2234 are respectively sleeved on both ends of the mounting shaft 2232. The limiting groove 2235 is designed as a long strip, and its length is less than the width of the shelf 21.

[0062] This utility model employs a connecting assembly 223, which mainly consists of a connecting rod component and a snap-fit ​​component. The connecting rod component is primarily connected to the drive assembly 222 and the housing 221, while the snap-fit ​​component is connected to the shelf 21. This detachable design not only reduces the manufacturing difficulty of the connecting assembly 223 but also greatly facilitates subsequent installation, maintenance, and replacement. When the connecting assembly 223 is damaged, it does not require complete replacement; only the damaged connecting rod component or snap-fit ​​component needs to be replaced, thereby reducing maintenance costs and time.

[0063] Of course, in other alternative implementations, an integrated connecting component 223 can be used to connect the drive component 222 and the shelf 21, so that the connecting component 223 can effectively drive the shelf 21 to achieve the flipping function under the action of the drive component 222.

[0064] like Figure 5 , Figure 9 and Figure 10 As shown, the drive assembly 222 includes a drive motor 2221, a transmission link 2222, and a crankshaft 2223. The crankshaft 2223 is rotatably connected between the drive motor 2221 and the transmission link 2222, and the transmission link 2222 is connected to the transmission shaft 2233.

[0065] The drive assembly 222 of this invention can be powered by an electric motor. Specifically, after the drive motor 2221 starts, the crankshaft 2223 rotates, which in turn drives the transmission connecting rod 2222 to rotate. The transmission connecting rod 2222 pulls the sliding shaft 2231 through the transmission shaft 2233, causing it to slide within the sliding groove 2211 of the sleeve 221, thereby realizing the flipping of the shelf 21. This design can precisely ensure the adjustment of the shelf 21 angle and has a low cost.

[0066] Of course, in other alternative implementations, the drive assembly 222 may use a cylinder as the power drive.

[0067] In addition, the snap-fit ​​body is equipped with a pressure sensor to detect whether there are items on the shelf 21. In practical applications, the pressure sensor can be installed at the contact point between the snap-fit ​​body and the shelf 21 to monitor the weight changes of the items on the shelf 21 in real time. When an item is placed on the shelf 21, the pressure sensor converts the sensed pressure signal into an electrical signal and transmits it to the refrigerator's control system. The control system determines whether there are items on the shelf 21 and their approximate weight based on the received electrical signal. Based on this determination, the system can be set to allow the flipping mechanism 22 to activate and flip the shelf 21 only when there are no items on the shelf 21, thereby avoiding damage to the items on the shelf 21 due to flipping.

[0068] like Figure 6 and Figure 7As shown, in the flipping mechanism 22, the opposite side walls of the sleeve 221 are provided with multiple parallel sliding grooves 2211, the main body of the connecting rod is provided with multiple parallel sliding shafts 2231, the multiple sliding shafts 2231 are connected to the multiple sliding grooves 2211 one by one, the multiple sliding shafts 2231 are connected to the same connecting rod, and the transmission shaft 2233 is provided on the connecting rod.

[0069] It should be noted that the number of sliding shafts 2231 on the connecting rod body can be flexibly set according to actual needs. For example, the connecting rod body may have two sliding shafts 2231. Furthermore, the drive shaft 2233 can be connected to the ends of multiple sliding shafts 2231 via connecting rods, or it can be connected to the middle of multiple sliding shafts 2231 via connecting rods. The former is mostly used when two drive components 222 work together to drive one connecting component 223, in which case there are two drive shafts 2233, each connected to both ends of multiple sliding shafts 2231 via connecting rods; the latter is mostly used when a single drive component 222 drives one connecting component 223, in which case only one drive shaft 2233 is needed.

[0070] This invention features multiple sliding shafts 2231 on the connecting rod body, and a corresponding number of sliding grooves 2211 on the sleeve 221, ensuring that these sliding shafts 2231 can be synchronously driven by the drive assembly 222. This design effectively improves the stability of the movement of the connecting assembly 223, thereby ensuring the smoothness of the shelf 21 during the flipping process.

[0071] like Figure 5 As shown, in the flipping mechanism 22, two drive components 222 are respectively disposed on the opposite side walls of the sleeve 221, and are respectively connected to the two sides of the connecting component 223 for transmission.

[0072] This invention uses two drive components 222 to drive a single connecting component 223. This design not only improves the stability of the connecting component 223's movement but also increases its speed, thereby ensuring the smoothness and efficiency of the shelf 21's flipping process. In practical applications, the two drive components 222 can provide power simultaneously, effectively avoiding the power shortage or instability that may occur with a single drive component 222. At the same time, because the two drive components 222 are respectively connected to both sides of the connecting component 223, the connecting component 223 experiences more balanced force during movement, reducing swaying or offset caused by uneven force. This design not only enhances the reliability of the shelf 21's flipping but also extends the service life of the entire refrigerator shelf structure.

[0073] like Figure 4 and Figure 5 As shown, in the flipping mechanism 22, multiple connecting components 223 are arranged vertically at intervals and are slidably mounted on a sleeve 221. The multiple connecting components 223 are connected to the multiple shelves 21 one by one.

[0074] It should be noted that the number of connecting components 223 in a single flipping mechanism 22 can be flexibly configured according to actual needs. For example, a flipping mechanism 22 may contain two connecting components 223 for connecting two shelves 21.

[0075] This invention achieves an integrated design by integrating multiple connecting components 223 into a single housing 221 and cooperating with multiple shelves 21. This design not only optimizes the spatial layout and increases the usable space inside the refrigerator, but also reduces direct contact between the connecting components 223 and other parts by utilizing the enclosing effect of the housing 221, effectively reducing the risk of damage caused by collisions and other factors.

[0076] like Figure 11 and Figure 12 As shown, there are two flipping mechanisms 22, which are respectively connected to both sides of the shelf 21 and work together to drive the shelf 21 to flip in a clockwise or counterclockwise direction.

[0077] This invention employs two flipping mechanisms 22 connected to both sides of the shelf 21, resulting in a more balanced force distribution on the shelf 21 during movement. Simultaneously, it accelerates the movement speed of the shelf 21, thereby ensuring the stability and efficiency of the shelf 21's flipping process. This design is particularly suitable for side-by-side refrigerators.

[0078] Based on the aforementioned refrigerator structure, the refrigerator shelf control method includes the following steps:

[0079] Cleaning instructions received;

[0080] Start the flipping mechanism 22 to drive the shelf 21 to flip.

[0081] In practical applications, when a user needs to clean the refrigerator and removes shelf 21, they can issue a cleaning command through the control panel.

[0082] Upon receiving a cleaning instruction, this utility model activates the flipping mechanism 22, driving the shelf 21 to flip, so that the shelf 21 is in an inclined state, thereby facilitating the user's disassembly operation.

[0083] After receiving the cleaning instruction, but before activating the flipping mechanism 22, the following steps are also included:

[0084] Obtain the pressure value measured by the pressure sensor;

[0085] Determine whether there are items placed on shelf 21 based on the pressure value;

[0086] If not, then the flipping mechanism 22 is allowed to be activated.

[0087] Upon receiving a cleaning instruction, this invention further determines whether there are any items placed on the shelf 21, so as to ensure that the flipping mechanism 22 is activated when there are no items on the shelf 21, thereby avoiding damage to the items on the shelf 21 due to the flipping operation.

[0088] For ease of understanding, the structure and control method of the refrigerator shelf 21 will be described in detail below through a preferred embodiment.

[0089] like Figures 5 to 8 As shown, the refrigerator shelf structure consists of shelves 21 and flipping mechanisms 22. There are two shelves 21, arranged vertically at intervals; there are also two flipping mechanisms 22, located on opposite sides of the inner compartment 13.

[0090] The flipping mechanism 22 includes a housing 221, four drive components 222, and two connecting components 223. The two connecting components 223 are arranged vertically at intervals, and each connecting component 223 is synchronously driven by the two drive components 222.

[0091] Each of the opposite side walls of the sleeve 221 is provided with two sets of sliding grooves 2211, arranged vertically at intervals. Each set of sliding grooves 2211 consists of two parallel sliding grooves 2211. Each of the opposite side walls of the sleeve 221 is provided with two motor holes 2212, arranged vertically at intervals.

[0092] Each linkage assembly includes a connecting body with two parallel sliding shafts 2231 that mate with the sliding grooves 2211 of the housing 221. Both ends of the two sliding shafts 2231 are connected by connecting rods, and each connecting rod has a drive shaft 2233. The connecting body also has a mounting shaft 2232. The linkage assembly further includes a snap-fit ​​body with two mounting mating parts 2234, each with a shaft hole 22340 for mates with the mounting shaft 2232. The snap-fit ​​body also has a limiting groove 2235 for mates with one side of the shelf 21. The snap-fit ​​body also has a pressure sensor.

[0093] Each drive assembly 222 includes a drive motor 2221, a crankshaft 2223, and a transmission connecting rod 2222. The drive motor 2221 is installed in the motor hole 2212 of the housing 221. The crankshaft 2223 is rotatably connected between the drive motor 2221 and the transmission connecting rod 2222. The transmission connecting rod 2222 is connected to the transmission shaft 2233.

[0094] like Figure 11 and Figure 12As shown, regarding the two flipping mechanisms 22, during the flipping process of the shelf 21, the two connecting components 223 connected to the same shelf 21 move in opposite directions in the slide 2211: one moves upward and the other moves downward. When the shelf 21 is in a horizontal state, the sliding shaft 2231 of one connecting component 223 is located at the bottom of the slide 2211, while the sliding shaft 2231 of the other connecting component 223 is located at the top of the slide 2211; when the shelf 21 switches from a horizontal state to a tilted state, the sliding shaft 2231 of one connecting component 223 moves upward to the top of the slide 2211, while the sliding shaft 2231 of the other connecting component 223 moves downward to the bottom of the slide 2211.

[0095] The specific methods for controlling refrigerator shelves are as follows:

[0096] When the user needs to disassemble shelf 21, all items on shelf 21 should be removed first. At this time, the pressure value measured by the pressure sensor is the weight of shelf 21, and the system will allow the drive motor 2221 to start. If the pressure value measured by the pressure sensor exceeds the weight of shelf 21, it indicates that there are still items on shelf 21 that have not been removed, and the system will issue an alarm to remind the user to completely remove the items.

[0097] After the items are emptied, the user needs to press the cleaning button on the control panel, which will start the drive motor 2221. The motor drives the crankshaft 2223 to rotate, which in turn drives the transmission connecting rod 2222 to rotate, thereby driving the connecting rod assembly to move along the slide rail 2211. The left connecting rod assembly slides upward and the right connecting rod assembly slides downward, realizing the flipping of the shelf 21. After the flipping is completed, the left connecting rod assembly reaches the top of the slide rail 2211 and the right connecting rod assembly reaches the bottom of the slide rail 2211, ensuring that the shelf 21 will not collide with the door 12 when it is disassembled and pulled out.

[0098] After cleaning the shelf 21, the user should insert it into the limiting groove 2235 and secure it at the flipped angle. Then, press the cleaning button on the control panel again, and the drive motor 2221 will start and flip the shelf 21 back to the horizontal position through the connecting assembly 223.
