Description

Technical Field

[0001] This application relates to the field of dishwasher technology, and in particular to a shelf structure and a dishwasher. Background Technology

[0002] Dishwashers are kitchen appliances that can significantly reduce the burden of housework and improve the efficiency and hygiene standards of dishwashing.

[0003] Dishwashers typically have shelves and trays, with the trays mounted on the shelves. Bowls, plates, chopsticks, spoons, cups, and other tableware or drinking utensils can be placed on the shelves and trays for subsequent washing.

[0004] However, the installation stability of the pallets in the relevant technologies is insufficient. Utility Model Content

[0005] This application provides a shelf structure and a dishwasher to improve the installation stability of the tray.

[0006] In a first aspect, embodiments of this application provide a shelf structure, including:

[0007] tray;

[0008] The shelf includes a vertical support frame, which includes multiple horizontal structural members and multiple vertical structural members. The horizontal and vertical structural members are interconnected and together define a mesh structure.

[0009] A connector includes a rotatable connecting part, to which the tray is rotatably connected; the connector also has a first limiting part and a second limiting part on the side of the rotatable connecting part away from the tray.

[0010] The first limiting part is detachably connected to the transverse structural member to limit the displacement of the connecting member in the first direction, which is parallel to the extension direction of the vertical structural member.

[0011] The second limiting part is located at the edge of the connector in the second direction and can be selectively and detachably connected to the vertical structural member to limit the displacement of the connector in the second direction, which is parallel to the extension direction of the transverse structural member.

[0012] The shelf structure of this embodiment includes a tray, a shelf, and a connector. The connector, through a rotating connection, allows the tray to be flipped upwards and folded away when not in use, reducing its footprint inside the dishwasher. When in use, it can be flipped downwards to a horizontal position, ensuring stable placement of tableware. The connector, through a first limiting part and a second limiting part, allows the tray to be rotatably mounted on the vertical support frame. Furthermore, since the first and second limiting parts limit the connector from the vertical and horizontal directions respectively, it helps improve the installation stability of the tray, thereby enhancing the overall installation stability of the tray.

[0013] Secondly, the connector is detachably connected to the horizontal structural member through the first limiting part, and selectively connected to the vertical structural member through the second limiting part, so that the pallet can be freely disassembled. This makes it convenient for users to install or disassemble the pallet according to their needs. Furthermore, the height of the pallet in the vertical direction can be adjusted by adjusting the connection position of the first limiting part with the horizontal structural members of different heights.

[0014] Meanwhile, because the connection is made to or disconnected from different vertical structural components via the second limiting part, the position of the tray in the horizontal direction can be adjusted, thereby improving the flexibility of the shelf for placing tableware. Users can adjust the position of the tray according to the height and size of the tableware, rationally plan the shelf space, adapt to tableware of different sizes, and avoid the problem of large tableware being affected by the fixed position of the tray.

[0015] In some embodiments, the second limiting portion has a first limiting groove on the side facing the center of the connector;

[0016] The opening of the first limiting groove faces the vertical structural member, and at least part of the vertical structural member is disposed within the first limiting groove through the opening of the first limiting groove.

[0017] In some embodiments, the connector further includes a blocking portion, which is disposed on the side of the vertical structural member away from the second limiting portion, and there is a channel between the blocking portion and the second limiting portion for the vertical structural member to pass through, the channel being connected to the opening of the first limiting groove.

[0018] In some embodiments, the tray has a first position and a second position when rotating relative to the vertical support frame, wherein the tray is closer to the vertical support frame in the second position than in the first position;

[0019] The pallet also has an abutment on the side facing the shelf. When the pallet is in the first position, the abutment abuts against the bottom of the retaining part; when the pallet is in the second position, the abutment is located on the side of the retaining part away from the vertical support frame.

[0020] In some embodiments, the connector is provided with a second limiting portion on each side in the second direction.

[0021] In some embodiments, the first limiting portion has a second limiting groove, the opening of the second limiting groove facing the connected transverse structural member.

[0022] In some embodiments, the connector further includes a baffle located on the side of the rotatable connection facing the vertical support frame; the tray also has a rotation limiting portion on the side facing the vertical support frame.

[0023] The pallet has a first position and a second position when rotating relative to the vertical support frame. In the second position, the pallet is closer to the vertical support frame than in the first position. When the pallet rotates from the first position to the second position, the rotation limit part abuts against the baffle.

[0024] In some embodiments, the tray has a cutlery placement surface, and the cutlery placement surface has multiple hollow areas;

[0025] The rotation limiting part is located in the hollow area opposite to the baffle, and the surface of the rotation limiting part is flush with the tableware placement surface.

[0026] In some embodiments, the connector further includes a snap-fit ​​portion located on the side of the baffle facing the vertical support frame, and the tray further includes a snap-fit ​​portion;

[0027] In the second position, the tray engaging part engages with the latching part.

[0028] Secondly, embodiments of this application provide a dishwasher comprising:

[0029] Inner liner;

[0030] The aforementioned shelf structure is located within the inner liner.

[0031] The dishwasher of this application embodiment can improve the installation stability of the tray through the shelf structure, thereby improving the stability of the tableware placed on the tray. Attached Figure Description

[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] A dishwasher is a kitchen appliance that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Dishwashers generally clean tableware by spraying high-pressure water jets, heating detergent, and circulating water.

[0053] Dishwashers typically include racks for holding dishes, with storage space inside. The efficiency of a dishwasher depends in part on the number of dishes it can hold, and the efficient use of space is a key factor in maximizing the amount of food that can be washed in a single cycle.

[0054] Shelving units typically consist of shelves and trays, with the trays positioned on top of the shelves to further expand the vertical or horizontal placement space of the shelving unit, thereby increasing the capacity of tableware per load.

[0055] In related technologies, pallets are connected to shelves via connectors. The pallet is connected to the connector, and the connector is connected to the shelf. The connector has vertically positioned locking clips, allowing it to be secured to the corresponding engagement point on the shelf, thus enabling the pallet to be mounted on the shelf.

[0056] However, the connector is only constrained in the vertical direction of the shelf and is prone to displacement in the horizontal direction, which affects the stability of the tableware on the tray.

[0057] Based on this, this application provides a shelf structure and a dishwasher. The shelf structure includes a tray, a shelf, and a connector. The connector allows the tray to be folded upwards around the rotatable connector when not in use, reducing the space occupied inside the dishwasher. When in use, it can be folded downwards to a horizontal position, ensuring that tableware is placed stably. The connector, through a first limiting part and a second limiting part, allows the tray to be rotatably mounted on a vertical support frame.

[0058] Furthermore, since the first limiting part and the second limiting part limit the connector from the vertical and horizontal directions respectively, it helps to improve the installation stability of the pallet, thereby improving the installation stability of the pallet.

[0059] Secondly, the connector is detachably connected to the horizontal structural member through the first limiting part, and selectively connected to the vertical structural member through the second limiting part, so that the pallet can be freely disassembled. This makes it convenient for users to install or disassemble the pallet according to their needs. Furthermore, the height of the pallet in the vertical direction can be adjusted by adjusting the connection position of the first limiting part with the horizontal structural members of different heights.

[0060] Meanwhile, because the connection is made to or disconnected from different vertical structural components via the second limiting part, the position of the tray in the horizontal direction can be adjusted, thereby improving the flexibility of the shelf for placing tableware. Users can adjust the position of the tray according to the height and size of the tableware, rationally plan the shelf space, adapt to tableware of different sizes, and avoid the problem of large tableware being affected by the fixed position of the tray.

[0061] Figure 1 A schematic diagram of a shelf structure is shown. Figure 2 A rear view of a shelving structure is shown. Figure 3 A side view of a shelving structure is shown. In the figure, the X direction is the first direction, and the Y direction is the second direction. The following section will discuss this further. Figures 1 to 3 The structure of the shelving structure will be further explained.

[0062] Please see Figures 1 to 3 This application provides a shelf structure, which includes a tray 200, a shelf 100, and a connector 300.

[0063] The shelf 100 serves as the load-bearing foundation of the entire structure. The shelf 100 includes a vertical support frame 110, which includes multiple horizontal structural members 111 and multiple vertical structural members 112. The horizontal structural members 111 and the vertical structural members 112 are interconnected and together define a mesh structure.

[0064] The horizontal structural member 111 can extend horizontally along the shelf 100, and the vertical structural member 112 can extend vertically along the shelf 100. The horizontal structural member 111 and the vertical structural member 112 can be fixed by welding, snap-fit ​​connection, or other methods, so that the mesh structure formed by the two can not only ensure the overall structural strength of the shelf 100 and provide stable support for the tray 200 and tableware, but also reduce the structure's own occupation of the internal space of the dishwasher, while not affecting the flow of water during dishwasher washing.

[0065] The tray 200 serves to hold tableware, further increasing the overall tableware capacity of the shelf 100. The tray 200 can be a frame structure or a grid structure to hold tableware and allow cleaning solution for rinsing tableware to flow through the tray 200.

[0066] The tray 200 and the shelf 100 are connected by the connector 300.

[0067] The connector 300 includes a rotatable connection part 310, and the tray 200 is rotatably connected to the rotatable connection part 310.

[0068] The tray 200 and the connector 300 can be connected by hinges, shaft holes or other means to achieve a rotatable connection. When not in use, the tray 200 can be flipped up around the rotatable connector 310 to further reduce the space occupied inside the dishwasher. When in use, it can be flipped down to a horizontal position to ensure that the tableware is placed stably.

[0069] For example, the rotating connection part 310 is provided with a snap-fit ​​groove, and the tray 200 is provided with a rotating shaft. The rotating shaft is rotatably disposed in the snap-fit ​​groove and is limited by the snap-fit ​​groove. The rotating shaft of the tray 200 is rotatably connected to the snap-fit ​​groove of the rotating connection part 310, so that the tray 200 can rotate relative to the rotating part.

[0070] For further information, please refer to [link / reference]. Figures 4 to 6 The connector 300 also has a first limiting part 320 and a second limiting part 330 on the side of the rotating connecting part 310 away from the tray 200.

[0071] The first limiting part 320 is detachably connected to the transverse structural member 111 to limit the displacement of the connecting member 300 in the first direction X. The first direction X is parallel to the extension direction of the vertical structural member 112, that is, the first direction X is the same as the vertical direction of the shelf 100.

[0072] The first limiting part 320 and the transverse structural member 111 can be detachably connected by a snap-fit ​​engagement. When the first limiting part 320 is connected to the transverse structural member 111, it can prevent the connecting member 300 from moving up and down in the vertical direction, ensuring the stability of the pallet 200 in the vertical direction.

[0073] The second limiting part 330 is located at the edge of the connector 300 in the second direction Y and can be selectively and detachably connected to the vertical structural member 112 to limit the displacement of the connector 300 in the second direction Y. The second direction Y is parallel to the extension direction of the transverse structural member 111, that is, the second direction Y is the same as the horizontal direction of the shelf 100.

[0074] The second limiting part 330 and the vertical structural member 112 can also be detachably connected by a snap-fit ​​engagement. When it is necessary to fix the horizontal position of the tray 200, the second limiting part 330 can be connected to the vertical structural member 112 to restrict the left and right movement of the connecting member 300 in the horizontal direction. When it is necessary to adjust the position of the tray 200 or disassemble the tray 200, the connection between the second limiting part 330 and the vertical structural member 112 can be released, making the operation convenient.

[0075] Since the second limiting part 330 is located at the edge of the connector 300 in the second direction Y, when the connector 300 is installed on the shelf 100, the connector 300 can be easily installed on the transverse structural member 111 through the second limiting part 330 at the edge, thereby helping to improve the ease of installation of the connector 300 and the shelf 100.

[0076] The shelf structure provided in this embodiment, through the provision of the first limiting part 320 and the second limiting part 330, enables the tray 200 to be rotatably mounted on the vertical support frame 110 via the connector 300. Furthermore, since the first limiting part 320 and the second limiting part 330 limit the connector 300 from the vertical and horizontal directions respectively, it helps to improve the installation stability of the tray 200, thereby ensuring that the tray 200 is firmly and stably fixed during use, preventing the tray 200 from shifting or falling off due to vibrations during dishwasher operation.

[0077] Secondly, the connector 300 is detachably connected to the horizontal structural member 111 via the first limiting part 320, and selectively connected to the vertical structural member 112 via the second limiting part 330, so that the tray 200 can be freely disassembled. This makes it convenient for users to install or disassemble the tray 200 according to their needs. Furthermore, by adjusting the connection position of the first limiting part 320 with the horizontal structural members 111 of different heights, the height of the tray 200 in the vertical direction can be adjusted.

[0078] Meanwhile, because the connector 300 connects or disconnects from different vertical structural members 112 via the second limiting part 330, the position of the tray 200 in the horizontal direction can be adjusted, thereby improving the flexibility of tableware placement on the shelf 100. Users can adjust the position of the tray 200 according to the height and size of the tableware, rationally plan the space of the shelf 100, adapt to tableware of different sizes, and avoid the problem of large tableware being affected by the fixed position of the tray 200.

[0079] To further improve the ease of assembly, flexibility, and installation stability when connecting the connector 300 to the vertical structural member 112, please refer to [link / reference needed]. Figure 5 and Figure 6 In some embodiments, the second limiting portion 330 has a first limiting groove 331 on the side facing the center of the connector 300.

[0080] The opening of the first limiting groove 331 faces the vertical structural member 112, and at least part of the vertical structural member 112 is disposed in the first limiting groove 331 through the opening of the first limiting groove 331.

[0081] The second limiting part 330 engages with the vertical structural member 112 through the first limiting groove 331, so that the connector 300 and the shelf 100 can be detachably connected.

[0082] It is understood that the groove size of the first limiting groove 331 is adapted to the cross-sectional size of the vertical structural member 112, ensuring that when the connector 300 is assembled with the vertical structural member 112, at least part of the vertical structural member 112 can be smoothly embedded into the groove through the groove of the first limiting groove 331 to form a stable locking fit.

[0083] The length direction of the first limiting groove 331 can be the same as the extension direction of the vertical structural member 112, that is, the first limiting groove 331 extends along the first direction X.

[0084] Since the opening of the first limiting groove 331 faces the vertical structural member 112, when the user needs to fix the connector 300 to a specific vertical structural member 112, there is no need to repeatedly adjust the relative position of the connector 300 and the vertical structural member 112. Simply align the opening of the first limiting groove 331 with the vertical structural member 112 and push the connector 300, and the vertical structural member 112 will naturally embed into the groove. This helps to improve the assembly convenience and flexibility of the connector 300. At the same time, the groove wall of the first limiting groove 331 can form a circumferential limit on the embedded vertical structural member 112, preventing the vertical structural member 112 from coming out of the edge of the connector 300 and improving the installation stability.

[0085] In some embodiments, to further improve the assembly reliability of the vertical structural member 112 and the second limiting portion 330, the connector 300 also includes a blocking portion 340. See also... Figure 6 The blocking part 340 is positioned on the side of the vertical structural member 112 away from the second limiting part 330, and there is a channel 341 between the blocking part 340 and the second limiting part 330 for the vertical structural member 112 to pass through. The channel 341 is connected to the slot of the first limiting groove 331.

[0086] Since the blocking part 340 is positioned on the side of the vertical structural member 112 away from the second limiting part 330, the blocking part 340 and the second limiting part 330 are arranged opposite each other. The channel 341 is located between the blocking part 340 and the second limiting part 330, and is in communication with the opening of the first limiting groove 331.

[0087] Thus, the blocking part 340 and the groove wall of the first limiting groove 331 can form a bidirectional limiting on the vertical structural member 112, confining the vertical structural member 112 within the first limiting groove 331, thereby enhancing the stability of the connection between the connector 300 and the vertical structural member 112, as well as the stability of the connection between the tray 200 and the shelf 100.

[0088] Furthermore, the channel 341 provides a clear path for the vertical structural component 112 to enter, preventing misalignment during the assembly of the connector 300, thereby further improving the ease of assembly of the connector 300.

[0089] When the user assembles the connector 300 and the vertical structural member 112, the vertical structural member 112 can be aligned with the channel 341 between the blocking part 340 and the second limiting part 330, and the connector 300 can be pushed along the channel 341 so that the vertical structural member 112 slides into the opening of the first limiting groove 331 along the channel 341 and is finally embedded in the first limiting groove 331.

[0090] After the vertical structural member 112 is embedded in the first limiting groove 331, the blocking part 340 is located on the side of the vertical structural member 112 away from the second limiting part 330, which can directly block the vertical structural member 112 from moving away from the second limiting part 330, and effectively prevent the vertical structural member 112 from coming out of the groove of the first limiting groove 331.

[0091] Figure 7 A schematic diagram of the shelf structure with the tray 200 in the first position is shown. Figure 8 A schematic diagram of the shelf structure with the tray 200 in the second position is shown below. Figure 7 and Figure 8 The shelf structure will be further elaborated.

[0092] Please see Figure 7 and Figure 8 In some embodiments, the tray 200 has a first position and a second position when rotating relative to the vertical support frame 110, and the tray 200 is closer to the vertical support frame 110 in the second position than in the first position.

[0093] The first position corresponds to the tray 200 when it is folded down, and the second position corresponds to the tray 200 when it is folded up. Compared to the first position, when the tray 200 is in the second position, it is closer to the vertical support frame 110, thereby minimizing the space occupied inside the dishwasher when folded up.

[0094] To achieve stable positioning of the pallet 200 at different rotational positions, the pallet 200 also has an abutment portion 210 on the side facing the shelf 100. The position of the abutment portion 210 is adapted to the stop portion 340 on the connector 300, and forms different engagement relationships with the stop portion 340 as the pallet 200 rotates.

[0095] Please see Figure 7 When the tray 200 is in the first position, the abutting portion 210 abuts against the bottom of the blocking portion 340. (See also...) Figure 8 When the tray 200 is in the second position, the abutment portion 210 is located on the side of the blocking portion 340 away from the vertical support frame 110.

[0096] When the tray 200 rotates to the first position, the abutment portion 210 abuts against the bottom of the stop portion 340, and the physical contact between the two forms a downward rotation limit. At this time, the tray 200 needs to bear the weight of the tableware. The contact between the abutment portion 210 and the stop portion 340 can effectively prevent the tray 200 from continuing to rotate downward due to its own weight or the pressure of the tableware, ensuring that the tray 200 can maintain a horizontal usage posture, which helps to improve the load-bearing stability of the tray 200 during use.

[0097] Please see Figure 9 and Figure 10 When the tray 200 rotates to the second position, the tray 200 flips upward around the rotating connection part 310 and gradually approaches the vertical support frame 110. The position of the abutment part 210 changes accordingly and is finally located on the side of the blocking part 340 away from the vertical support frame 110. The abutment part 210 can be in a suspended state and does not cooperate with other structural components.

[0098] It is understood that the blocking part 340 is located on the rotation path of the abutment part 210. When the pallet 200 rotates from the second position to the first position, the abutment part 210 rotates to abut against the bottom of the blocking part 340, thereby achieving a limiting engagement. When the abutment part 210 abuts against the blocking part 340, the abutment part 210 and the blocking part 340 can be in a surface-to-surface contact state to increase the contact area of ​​the abutment part 210, thereby dispersing the load transmitted from the pallet 200 and helping to improve the limiting stability of the abutment part 210.

[0099] Please continue reading. Figure 5 and Figure 6 In some embodiments, the connector 300 is provided with a second limiting part 330 on each side of the second direction Y.

[0100] The two second limiting parts 330 can be symmetrically distributed on the connector 300, and their respective structural forms can be kept consistent, together forming a bidirectional limiting structure for the connector 300 in the horizontal direction.

[0101] Since the vertical structural members 112 of the vertical support frame 110 are distributed at intervals along the second direction, when the connector 300 needs to be fixed to the vertical support frame 110, the second limiting part 330 on one or both sides of the connector 300 can be connected to the corresponding vertical structural member 112 according to the actual installation position requirements. If it is only necessary to limit the displacement of the connector 300 on one side in the second direction, the first limiting groove 331 of the second limiting part 330 on one side can be engaged with the adjacent vertical structural member 112.

[0102] If it is necessary to achieve bidirectional stable positioning of the connector 300 in the second direction, the second limiting parts 330 on both sides can be engaged with the corresponding vertical structural members 112 respectively. At this time, the first limiting grooves 331 of the second limiting parts 330 on both sides respectively wrap around the corresponding vertical structural members 112, forming symmetrical constraints from both sides of the second direction, effectively limiting the left and right displacement of the connector 300 in the second direction, and preventing the connector 300 from shifting in the horizontal direction due to the vibration of the dishwasher.

[0103] Therefore, by providing a second limiting part 330 on both sides of the second direction Y of the connector 300 in this embodiment, the connector 300 does not need to be deliberately distinguished in terms of installation direction when it is engaged with the vertical support frame 110, which helps to further reduce the complexity of assembly operations and improve the convenience of user operation.

[0104] Please continue reading. Figure 5 and Figure 6 In some embodiments, the connector 300 is provided with a first limiting portion 320 on both sides in the first direction X.

[0105] The two first limiting parts 320 can be symmetrically or correspondingly distributed, and both first limiting parts 320 maintain a detachable connection with the transverse structural member 111 of the vertical support frame 110.

[0106] When the second limiting part 330 is not connected to the vertical structural member 112, the two first limiting parts 320 are respectively connected to the corresponding horizontal structural members 111 on the vertical support frame 110. The first limiting parts 320 on both sides of the connector 300 in the first direction X can simultaneously engage with two adjacent horizontal structural members 111. In this way, the connector 300 can be bidirectionally limited in the first direction X by connecting on both sides.

[0107] The first limiting portions 320 on both sides of the connector 300 can share the weight of the tray 200 and the tableware, preventing excessive force on one side from causing loosening of the connection or structural deformation. At the same time, when the dishwasher vibrates during operation, or when the tray 200 is subjected to a slight external force in the horizontal direction, the first limiting portions 320 on both sides of the connector 300 are connected to the transverse structural member 111, which can also effectively limit the displacement of the connector 300 in the first direction X, prevent the connector 300 from tilting or shifting, and ensure that the tray 200 always maintains a stable installation state.

[0108] Compared to setting the first limiting part 320 on one side, setting the first limiting part 320 on both sides in this embodiment can improve the installation stability of the connector 300 on the vertical support frame 110, so that when the second limiting part 330 is not connected to the vertical structural member 112, the tray 200 can also be stably installed on the vertical support frame 110 through the connector 300.

[0109] Please continue reading. Figure 5 and Figure 6 In some embodiments, the first limiting part 320 has a second limiting groove 321, and the opening of the second limiting groove 321 faces the connected transverse structural member 111.

[0110] The groove size and internal space of the second limiting groove 321 can be adapted to the cross-sectional shape of the transverse structural member 111, ensuring that the transverse structural member 111 can be accurately embedded in the second limiting groove 321 to form a tight engagement.

[0111] When the connector 300 is connected to the transverse structural member 111 through the first limiting part 320, since the opening of the second limiting groove 321 faces the transverse structural member 111 directly, the opening of the second limiting groove 321 needs to be aligned with the transverse structural member 111 and a slight pushing force needs to be applied so that the transverse structural member 111 can slide smoothly into the groove.

[0112] Meanwhile, after the transverse structural member 111 is embedded in the second limiting groove 321, the groove wall will form a wrapping limiting on the transverse structural member 111 from the circumferential direction. Compared with the connection method that relies only on surface contact without groove, the second limiting groove 321 can effectively limit the displacement of the transverse structural member 111 in the direction perpendicular to its own extension, thereby further improving the installation stability of the connector 300 in the first direction X, and further improving the installation stability of the tray 200.

[0113] Please continue reading. Figure 5 , Figure 6 and Figure 10 In some embodiments, the connector 300 further includes a baffle 350 located on the side of the rotatable connector 310 facing the vertical support frame 110. The tray 200 also has a rotation limiting portion 220 on the side facing the vertical support frame 110.

[0114] The baffle 350 can be integrated into the connector 300 and is located on the side of the rotating connection 310 facing the vertical support frame 110. Its extension direction is adapted to the rotation axis of the rotating connection 310, forming a physical blocking structure on the rotation path of the tray 200. The position and shape of the rotation limiting part 220 match the baffle 350, and it can precisely abut against the baffle 350 as the tray 200 rotates.

[0115] The tray 200 has a first position and a second position when rotating relative to the vertical support frame 110. Compared to the first position, the tray 200 is closer to the vertical support frame 110 in the second position. When the tray 200 rotates from the first position to the second position, the rotation limit part 220 abuts against the baffle 350.

[0116] When the tray 200 rotates relative to the vertical support frame 110, it still maintains the first position (folded down for use) and the second position (folded up for storage), and the second position is closer to the vertical support frame 110.

[0117] As the tray 200 rotates from the first position to the second position, that is, during the process of flipping and retracting from a horizontal bearing state, the tray 200 drives the rotation limiting part 220 to rotate synchronously. As the rotation angle gradually increases, the rotation limiting part 220 gradually approaches the baffle 350 on the connecting member 300 until the tray 200 rotates to the second position, at which point the rotation limiting part 220 exactly abuts against the baffle 350, and the two form rigid contact. In this way, the baffle 350 prevents the rotation limiting part 220 from moving further through its own structural strength, thereby limiting the tray 200 from rotating further upward and accurately locking the tray 200 to the retracted position.

[0118] Therefore, in this embodiment, the cooperation between the baffle 350 and the rotation limit part 220 provides the maximum rotation angle for the tray 200 through physical contact, ensuring that the tray 200 can accurately stop when it rotates to the folded position each time. This avoids collision damage between the tray 200 and the vertical support frame 110, improves the reliability and operational certainty during user use, and brings a better user experience.

[0119] Please continue reading. Figures 11 to 13 In some embodiments, the tray 200 has a tableware placement surface with multiple open areas 230.

[0120] During dishwasher operation, high-pressure cleaning water can penetrate the tray 200 through the perforated area 230, directly acting on the dishes on the upper and lower sides of the tray 200. This prevents the water from being unable to fully contact the surface of the dishes due to obstruction by the tray 200, thereby improving cleaning coverage and cleanliness. Furthermore, the perforated area 230 of the tray 200 reduces the amount of material used and lowers the overall weight of the tray 200 while ensuring its load-bearing strength. This saves production costs and makes it easier for users to install, disassemble, or flip the tray 200.

[0121] The rotation limiting part 220 is located in the hollow area 230 opposite to the baffle 350, and the surface of the rotation limiting part 220 is flush with the tableware placement surface.

[0122] The rotation limiting part 220 is located in the hollow area 230 opposite to the baffle 350. On the one hand, the space of the hollow area 230 can be used to realize the integrated installation of the rotation limiting part 220 without having to open up additional installation space on the tableware placement surface, thus avoiding the rotation limiting part 220 protruding from the placement surface and affecting the stable placement of the tableware.

[0123] Furthermore, since the surface of the rotating limiting part 220 is flush with the tableware placement surface, the tableware will not tilt or fail to fit the placement surface due to the protrusion of the limiting part when it is placed, thus ensuring load-bearing stability.

[0124] Please continue reading. Figure 5 , Figure 6 and Figure 10 In some embodiments, the connector 300 further includes a latching portion 360 located on the side of the baffle 350 facing the vertical support frame 110, and the tray 200 further includes a snap-fit ​​portion 240. When the tray 200 is in the second position, the tray 200 is snapped into place by the snap-fit ​​portion 240 and the latching portion 360, thereby placing the tray 200 in a locked and folded state in the second position.

[0125] The latching part 360 can be integrated into the connector 300 and is located on the side of the baffle 350 facing the vertical support frame 110. Its structure can be designed as an elastic hook, a protruding latch, etc., with a certain deformation capability to adapt to the latching operation. Correspondingly, the tray 200 is provided with a latching part 240 on the side facing the vertical support frame 110, which is adapted to the latching part 360. The latching part 240 can adopt a slot, a notch, or a protrusion structure adapted to the hook, and can form a detachable latching engagement with the latching part 360 as the tray 200 rotates.

[0126] As the tray 200 rotates from the first position (folded-down use position) to the second position, the tray 200 causes the locking part 240 to move synchronously closer to the baffle 350 of the connector 300. As the rotation limiting part gradually abuts against the baffle 350, the locking part 240 also gradually aligns with the latching part 360 on the baffle 350. When the tray 200 is fully rotated to the second position, the locking part 240 and the latching part 360 engage under a slight external force.

[0127] If the latching part 360 is an elastic hook, it will engage with the slot of the engaging part 240 after deformation, forming a mechanical lock. If the latching part 360 is a protruding structure, it will embed into the recess of the engaging part 240, and the two will restrict the tray 200 from rotating in the opposite direction through structural interlocking. Through the above-mentioned interlocking engagement, the tray 200 can be stably fixed in the second position, preventing it from falling back to the first position on its own without external force.

[0128] Therefore, this embodiment improves the stability of the tray 200 in the second position by rotating the limiting part to abut against the baffle 350 and fixing the posture by the cooperation of the buckle and the snap.
