Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to a tray assembly and a dishwasher. Background Technology

[0002] As a common kitchen appliance, dishwashers can automatically handle the cleaning of various tableware such as bowls, chopsticks, plates, dishes, knives, and forks, improving the efficiency of tableware cleaning and saving users a lot of time and energy.

[0003] When using a dishwasher, dishes are typically placed in the rack assembly, while slender cutlery such as chopsticks are placed on the tray. Existing trays are simply attached to the rack assembly with a snap-fit ​​structure, which is unstable. During dishwasher operation, the internal spray arms spray high-pressure water, causing the entire rack assembly to vibrate at high frequency. This can lead to problems such as the tray rotating, shaking, or even falling off the rack and damaging the cutlery.

[0004] Therefore, it is urgent to solve the technical problem of poor stability of pallet components installed on shelf components, which makes them prone to rotation and shaking. Utility Model Content

[0005] This utility model provides a tray assembly and a dishwasher to solve the technical problem of poor stability of the tray assembly when installed on the shelf assembly, which is prone to rotation and shaking.

[0006] To achieve the above objectives, this utility model provides a tray assembly mounted on a shelf assembly. The shelf assembly includes a mounting portion, which includes interleaved horizontal and vertical bars. The tray assembly includes:

[0007] Tray body;

[0008] The mounting structure is disposed on the pallet body and includes: a first fastening member, which is disposed on the outer wall of the pallet body, and a first slot is formed between the first fastening member and the outer wall of the pallet body. A second slot is provided in the first fastening member, and the openings of the first slot and the second slot are both facing the bottom of the pallet body.

[0009] The horizontal bar is engaged in the first slot, and the top end of the vertical bar is engaged in the second slot to lock the tray assembly to the shelf assembly.

[0010] This application provides a tray assembly in which a first groove is formed between a first fastening member and the outer wall of the tray body, and a second groove is provided in the first fastening member. By engaging a crossbar in the first groove, the tray assembly is constrained in the width direction. When the tray assembly is not in use, the tray body is rotated to a vertical or approximately vertical position. At this time, the top end of the crossbar is engaged in the second groove, constraining the tray assembly in the length direction, thereby locking the tray assembly to the shelf assembly. This improves the stability of the tray assembly installation, allowing the tray assembly to remain vertical or approximately vertical on the shelf assembly. It greatly enhances the tray assembly's vibration and overturn resistance, effectively preventing the tray assembly from falling off the shelf assembly during dishwasher operation due to vibrations or other factors.

[0011] In one possible implementation, the second slot includes a fitting groove and a guide groove, a first end of the guide groove communicating with the fitting groove, and a second end of the guide groove extending to the opening of the second slot, the guide groove being used to guide the top end of the vertical rod to engage within the fitting groove;

[0012] From the opening of the second slot to the fitting slot, the width of the guide slot gradually decreases.

[0013] In one possible implementation, the second slot further includes a locking protrusion connected to the first end of the guide groove and protruding from the inner wall of the guide groove.

[0014] In one possible implementation, the mounting structure further includes: a second fastening member, which is spaced apart from the first fastening member on the outer wall of the pallet body, and a third slot is formed between the second fastening member and the outer wall of the pallet body, the opening of the third slot facing the bottom of the pallet body, and the third slot and the first slot are used to engage with the crossbar on the same side.

[0015] In one possible implementation, the mounting structure further includes a support portion disposed on the outer wall of the tray body, the support portion having a support groove located at one end of the support portion opposite to the opening of the first slot, the support groove being used to support the crossbar.

[0016] In one possible implementation, the tray body includes:

[0017] The bottom mesh and the surrounding plate are arranged around the bottom mesh, and the surrounding plate and the bottom mesh together form a receiving cavity. The mounting structure is arranged on the outer wall of the surrounding plate.

[0018] In one possible implementation, the bottom mesh has multiple grids connected to a water-breaking membrane structure, the water-breaking membrane structure comprising:

[0019] At least one water-breaking membrane reinforcement strip, the first end of which is connected to the inner wall surface of the grid, the second end of which extends to the center of the grid, and the first end of which is higher than the second end of which is higher.

[0020] In one possible implementation, the water-breaking membrane structure further includes:

[0021] A water-breaking membrane column is provided at the second end of the water-breaking membrane rib, and the water-breaking membrane column protrudes into the receiving cavity;

[0022] A water guide column is disposed at the second end of the water-breaking membrane rib, and the water guide column protrudes from the side opposite to the receiving cavity.

[0023] In one possible implementation, the bottom mesh includes a support area and a recessed area spaced apart along the length of the pallet body, each of the support area and the recessed area having a plurality of meshes;

[0024] Along a direction perpendicular to the bottom mesh plane, the position of the mesh in the bearing area is higher than the position of the mesh in the sinking area.

[0025] This application also provides a dishwasher, including: a dishwasher body and the aforementioned tray assembly.

[0026] The tray assembly and dishwasher provided in this application embodiment, by setting a limiting rib plate in the receiving cavity, and the top of the limiting rib plate is provided with multiple limiting grooves, after the chopsticks are placed in the receiving cavity, the limiting grooves play a limiting role on the chopsticks, which can prevent the chopsticks from moving during the washing process and keep the chopsticks stable.

[0027] The tray assembly and dishwasher provided in this application embodiment have an outer diameter that gradually increases from the top to the bottom of the water-breaking film column. When the water-breaking film column comes into contact with the water surface, its contact area decreases with the increase of height, which helps the water-breaking film column penetrate the water surface more deeply, thereby more effectively breaking the surface tension of the water, improving the effect of water droplet falling, and improving drying efficiency.

[0028] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems solved by the tray assembly and dishwasher provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

[0082] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0083] In a dishwasher, the tray assembly provides support for the dishes, ensuring that they remain stable during the washing process and do not move or collide due to the impact of the water flow. A good tray assembly can optimize the contact of the water flow, allowing the water to effectively cover the surface of the dishes, thereby improving the washing and drying effects. The design of the tray assembly is crucial to the overall performance of the dishwasher and affects the washing results.

[0084] During dishwasher operation, the high-pressure water jets from the internal spray arms cause the rack assembly to vibrate continuously at high frequency. The existing tray's snap-fit ​​structure is relatively simple, and the connection between it and the rack assembly lacks effective constraints. This causes the tray to easily rotate, shake, or even detach from the rack under vibration, which not only affects the stable support of tableware but may also cause tableware to collide, be damaged, or fall.

[0085] In view of this, the tray assembly and dishwasher provided by this utility model form a first groove between the first fastening member and the outer wall of the tray body, and a second groove is provided in the first fastening member. By locking the crossbar in the first groove, the tray assembly is constrained in the width direction. When the tray assembly is not in use, the tray body is rotated to a vertical or approximately vertical position. At this time, the top of the vertical bar is locked in the second groove, constraining the tray assembly in the length direction, thereby locking the tray assembly to the shelf assembly. This improves the stability of the tray assembly installation, allowing the tray assembly to remain vertical or approximately vertical on the shelf assembly. This greatly enhances the tray assembly's vibration and overturn resistance, effectively preventing the tray assembly from falling off the shelf assembly during dishwasher operation.

[0086] The tray assembly and dishwasher provided in the embodiments of this utility model are described below with reference to the accompanying drawings.

[0087] refer to Figure 1 , Figure 3 and Figure 6 As shown, this application embodiment provides a tray assembly, which is installed on a shelf assembly 60. The shelf assembly 60 includes a mounting part 61, which includes crossbars 611 and vertical bars 612 arranged in an alternating manner.

[0088] refer to Figure 1 and Figure 3 As shown, this application embodiment provides a pallet assembly, including a pallet body 10 and a mounting structure 50. The mounting structure 50 is disposed on the pallet body 10 and includes: a first fastening member 51, which is disposed on the outer wall of the pallet body 10, forming a first slot 54 between the first fastening member 51 and the outer wall of the pallet body 10, and a second slot 55 is provided in the first fastening member 51. The openings of the first slot 54 and the second slot 55 both face the bottom of the pallet body 10; a horizontal bar 611 is engaged in the first slot 54, and the top end of the vertical bar 612 is engaged in the second slot 55 to lock the pallet assembly to the shelf assembly 60.

[0089] This application provides a tray assembly in which a first slot 54 is formed between a first fastening member 51 and the outer wall of the tray body 10. A second slot 55 is provided in the first fastening member 51. By engaging a crossbar 611 in the first slot 54, the tray assembly is constrained in the width direction. When the tray assembly is not in use, the tray body 10 is moved along... Figure 8When the vertical rod 612 is rotated to a vertical or approximately vertical position in the -P direction, the top end of the vertical rod 612 is engaged in the second slot 55, which constrains the tray assembly along its length to lock the tray assembly to the shelf assembly 60. This improves the stability of the tray assembly installation, greatly enhances the tray assembly's vibration and overturn resistance, and effectively prevents the tray assembly from falling off the shelf assembly 60 during dishwasher operation.

[0090] The pallet assembly provided in this application embodiment can be installed onto the shelf assembly without any tools. The first fastener 51 is fastened onto the crossbar 611, and the pallet assembly is rotated downwards around the crossbar 611 as an axis, so that the bottom of the pallet assembly tends to be placed horizontally. During the process of the pallet assembly being rotated to the horizontal position, the top of the vertical bar 612 will slide into the second slot 55. The installation process is very simple and can be completed by simply snapping and rotating, realizing true quick installation and quick disassembly.

[0091] refer to Figure 6 and Figure 7 As shown, during installation, align the opening of the first slot 54 with the horizontal bar 611, align the second slot 55 with the top of the vertical bar 612, and then... Figure 7 Rotate the tray assembly in the direction indicated by arrow P so that the support 57 abuts against the lower side of the crossbar 611, locking the tray assembly to the shelf assembly 60.

[0092] In one possible implementation, when the tray assembly is not required, the tray assembly can be placed along... Figure 8 Rotating the shelf assembly 60 to a vertical or roughly vertical position, as indicated by arrow P, helps to clear space above the shelf assembly 60, allowing it to accommodate taller tableware and preventing interference with the tray assembly. When the tray assembly is needed, rotate it along... Figure 7 Rotate the tray in the direction indicated by arrow P until it is roughly horizontal. The tray assembly can also be used to place some tableware, making it more flexible and convenient to use.

[0093] During disassembly, along Figure 8 Rotate the tray assembly in the direction indicated by arrow -P to disengage the first fastener 51 from the crossbar 611 and the vertical bar 612, thereby removing the tray assembly from the shelf assembly 60 and unlocking the tray assembly from the shelf assembly 60.

[0094] The pallet assembly provided in this application embodiment has a first fastening member 51 made of plastic, and the horizontal bars 611 and vertical bars 612 of the shelf assembly 60 are typically made of metal. During the process of the horizontal bar 611 being engaged in the first slot 54 and the top of the vertical bar 612 being engaged in the second slot 55, the metal parts are prevented from scraping the horizontal bars 611 and vertical bars 612, effectively protecting the anti-corrosion coating on the metal surface of the horizontal bars 611 and vertical bars 612 of the shelf assembly 60, and ensuring the service life of the shelf assembly 60.

[0095] In one possible implementation method, refer to Figure 1 , Figure 3 and Figure 6 As shown, the second slot 55 includes a fitting slot 551 and a guide slot 552. The first end of the guide slot 552 is connected to the fitting slot 551, and the second end of the guide slot 552 extends to the opening of the second slot 55. The guide slot 552 is used for the top end of the vertical rod 612 to be engaged in the fitting slot 551.

[0096] In one possible implementation, the cross-sectional shape of the fitting groove 551 is consistent with the cross-sectional shape of the top end of the vertical rod 612. The fitting groove 551 and the top end of the vertical rod 612 are interference-fitted, which helps to stably embed the top end of the vertical rod 612 into the fitting groove 551 and improves the stability of the pallet assembly installation.

[0097] The guide groove 552 guides the top of the vertical rod 612 into the fitting groove 551. When the tray assembly is installed on the shelf assembly 60, even if the fitting groove 551 and the top of the vertical rod 612 are initially misaligned or not fully aligned, the guide groove 552 can still guide the top of the vertical rod 612 into the fitting groove 551 when the top of the vertical rod 612 enters the guide groove 552. This compensates for the initial positional deviation between the fitting groove 551 and the top of the vertical rod 612, ultimately achieving high-precision and reliable installation, effectively avoiding assembly interference or misalignment, and thus ensuring the accuracy of installation.

[0098] In one possible implementation, along the depth direction of the second slot 55, from the opening of the second slot 55 to the fitting groove 551, the width of the guide groove 552 gradually decreases. At the opening of the second slot 55, the guide groove 552 is the widest, and the wider opening facilitates the insertion of the tip of the vertical rod 612 into the guide groove 552. From the opening of the second slot 55 to the fitting groove 551, the guide groove 552 gradually narrows, facilitating the guidance of the tip of the vertical rod 612 through the guide groove 552 into the fitting groove 551, achieving the locking effect.

[0099] In one possible implementation, the second slot 55 further includes a locking protrusion 553, which is connected to the first end of the guide slot 552 and protrudes from the inner wall of the guide slot 552. The locking protrusion 553 forms a mechanical limit after the top end of the vertical rod 612 is inserted into the fitting slot 551, preventing the top end of the vertical rod 612 from accidentally dislodging from the fitting slot 551 due to vibration or external force, thereby improving the reliability and stability of the tray assembly installed on the shelf assembly 60.

[0100] In one possible implementation, the mounting structure 50 further includes: a second fastening member 52, which is spaced apart from the first fastening member 51 on the outer wall of the pallet body 10, and a third slot 56 is formed between the second fastening member 52 and the outer wall of the pallet body 10. The opening of the third slot 56 faces the bottom of the pallet body 10, and the third slot 56 and the first slot 54 are used to engage with the crossbar 611 on the same side.

[0101] By setting the second fastening member 52, the load borne by the first fastening member 51 is shared, the local stress is reduced, and the problem of the first fastening member 51 being damaged due to excessive load is avoided, thereby improving the durability and reliability of the overall structure.

[0102] The opening of the third slot 56 faces the bottom of the tray body 10, that is, the opening of the third slot 56 faces the same direction as the opening of the first slot 54, which makes it easy to quickly align the crossbar 611 and snap it into the third slot 56 and the first slot 54, thus improving assembly efficiency and accuracy.

[0103] The first fastener 51 and the second fastener 52 work together to achieve a snap-fit ​​constraint, which can suppress the relative movement or torsion between the tray assembly and the crossbar 611 under vibration or external impact, and prevent accidental disengagement.

[0104] In one possible implementation, the mounting structure 50 further includes a support portion 57 disposed on the outer wall of the tray body 10. The support portion 57 has a support groove 571 located at one end of the support portion 57 facing away from the opening of the first slot 54. The support groove 571 is used to support the crossbar 611 and prevent the crossbar 611 from accidentally coming out of the opening of the first slot 54 under vibration or external force.

[0105] In one possible implementation, the support groove 571 supports the side of the crossbar 611 facing the opening of the first slot 54, and the support portion 57 supports the crossbar 611 from below, enhancing the holding effect of the first slot 54 on the crossbar 611 and improving the overall stability after installation. The support portion 57 shares the load applied by the crossbar 611 to the first fastener 51, reducing the local stress of the first fastener 51 and extending the service life of the first fastener 51 structure.

[0106] In one possible implementation, the support 57 can be a support rib, and the support groove 571 can be an arc groove, thereby better supporting the crossbar 611.

[0107] In one possible implementation, the mounting structure 50 further includes a retaining protrusion 53 disposed on the outer wall of the pallet body 10, which abuts against the shelf assembly 60 when the pallet assembly is mounted to the shelf assembly 60.

[0108] The stop 53 serves as a mechanical stop structure, used to limit the relative position between the pallet assembly and the shelf assembly 60, effectively suppressing the sliding or displacement of the pallet assembly along the surface of the shelf assembly 60 after installation, and improving the overall structure's vibration and displacement resistance.

[0109] In addition, the 53-shaped baffle provides operators with clear tactile or visual alignment feedback, reducing installation difficulty and improving assembly efficiency. It can also prevent the pallet assembly from making large-area contact with the shelf assembly 60, thus preventing large-area wear of the shelf assembly 60.

[0110] In one possible implementation method, refer to Figure 1 , Figure 4 and Figure 10 As shown, the tray body 10 includes a bottom mesh 11 and a surrounding plate 12. The surrounding plate 12 is disposed around the bottom mesh 11, and the surrounding plate 12 and the bottom mesh 11 together form a receiving cavity 20. The mounting structure 50 is disposed on the outer wall of the surrounding plate 12. The receiving cavity 20 is used to receive tableware, such as chopsticks 71 and spoons 72.

[0111] In one possible implementation, the bottom mesh 11 has a plurality of grids 114 connected to a water-breaking membrane structure 30.

[0112] In one possible implementation, the bottom mesh 11 includes a bearing area 111 and a sinking area 112 spaced apart along the length of the pallet body 10, each bearing area 111 and sinking area 112 having a plurality of grids 114.

[0113] In one possible implementation, along a direction perpendicular to the plane of the bottom mesh 11, the position of the mesh 114 in the bearing area 111 is higher than the position of the mesh 114 in the sunken area 112. That is, the sunken area 112 is recessed downward relative to the bearing area 111.

[0114] The bearing area 111 and the sinking area 112 are arranged at intervals along the length of the bottom net 11, and the surrounding plate 12 is set on the periphery of the bottom net 11. The surrounding plate 12 and the bottom net 11 together form the receiving cavity 20.

[0115] The tray assembly provided in this application embodiment forms a receiving cavity 20 by means of a surrounding plate 12 and a bottom mesh 11. The bottom mesh 11 includes a supporting area 111 and a downwardly recessed sinking area 112. This structure makes the sinking area 112 lower than the supporting area 111. When chopsticks 71 are placed in the receiving cavity 20, the chopsticks 71 are supported by the supporting area 111, creating a certain space between the chopsticks 71 and the sinking area 112. This facilitates water flow to rinse the side of the chopsticks 71 facing the bottom mesh 11, and also helps air circulation, accelerating the drying process of the chopsticks 71. In addition, when the user picks up the chopsticks 71, they can put their fingers into the space between the chopsticks 71 and the sinking area 112, making it more convenient to pick up the chopsticks 71 and improving the user experience.

[0116] In one possible implementation method, refer to Figure 4 As shown, along the length of the bottom mesh 11, both ends of the bottom mesh 11 are load-bearing areas 111, and the sunken area 112 is arranged between the two load-bearing areas 111. The load-bearing areas 111 provide some support for tableware such as chopsticks 71.

[0117] In this example, the length direction of the base mesh 11 is referenced. Figure 1 and Figure 4 The direction indicated by the arrow X in the diagram is also the length direction of the tray assembly.

[0118] In another possible implementation not shown in the figure, along the length of the bottom net 11, the two ends of the bottom net 11 are a bearing area 111 and a sinking area 112, respectively, that is, the bearing area 111, the sinking area 112, the bearing area 111, and the sinking area 112 are arranged in sequence.

[0119] In other possible implementation methods, the number of bearing areas 111 can be three or more, and the number of sinking areas 112 can be three or more, with the bearing areas 111 and sinking areas 112 arranged at intervals along the length of the bottom net 11.

[0120] refer to Figure 1 and Figure 4 As shown, the enclosure 12 is disposed around the bottom mesh 11. The enclosure 12 forms the boundary of the tray assembly and helps to form a closed or semi-closed space in the tray assembly, namely the receiving cavity 20. The receiving cavity 20 is the main space for placing tableware. The enclosure 12 can prevent tableware from sliding out of the receiving cavity 20 during the washing process.

[0121] In one possible implementation, the enclosure 12 and the bottom mesh 11 can be an integrally formed structure, or they can be connected by means of screws or clips.

[0122] In one possible implementation, the enclosure 12 may be made of a durable and corrosion-resistant material to ensure its service life in high-temperature and humid environments.

[0123] In one possible implementation method, refer to Figure 1 and Figure 4 As shown, both the bearing area 111 and the sinking area 112 have multiple dividing ribs 113 to separate grids 114 within the bearing area 111 and the sinking area 112.

[0124] In one possible implementation, the multiple dividing ribs 113 can be arranged in a staggered pattern, so that the grid 114 can be triangular, rectangular, parallelogram-shaped, trapezoidal, etc. The size, shape, and number of the grid 114 can be flexibly designed according to usage requirements to accommodate different types of tableware. The passage of water and air through the grid 114 can improve the washing and drying effect.

[0125] In one possible implementation, the mesh 114 is connected to a water-breaking film structure 30, which is used to break the surface tension of the water flow, promote the uniform distribution of the water flow, prevent water droplets from staying on the surface of the tableware and the bottom mesh 11, reduce water droplet residue, and thus improve the efficiency of cleaning and drying.

[0126] In one possible implementation method, refer to Figure 1 and Figure 2 As shown, the water-breaking membrane structure 30 includes at least one water-breaking membrane rib 31. The first end of the water-breaking membrane rib 31 is connected to the inner wall surface of the grid 114, and the second end of the water-breaking membrane rib 31 extends to the center of the grid 114. The first end of the water-breaking membrane rib 31 is higher than the second end of the water-breaking membrane rib 31. This structure guides water flow from the first end of the water-breaking membrane rib 31 to the second end of the water-breaking membrane rib 31, promoting water flow towards the lowest position of the water-breaking membrane structure 30 to facilitate water discharge.

[0127] In one possible implementation, the water-breaking membrane rib 31 can be oblique or spiral. Under the action of its own gravity, the water droplets flow along the water-breaking membrane rib 31 to the second end of the water-breaking membrane rib 31, which is conducive to the discharge of water droplets in the receiving cavity 20.

[0128] In one possible implementation method, refer to Figure 4 and Figure 10 As shown, the water-breaking ribs 31 and the dividing ribs 113 divide the grid 114 into smaller holes, allowing the user to insert the spoon 72 upright into the holes, saving space in the receiving cavity 20 and improving the drying performance of the tray assembly.

[0129] Since both the bearing area 111 and the sinking area 112 have multiple grids 114, and the grids 114 are connected to the water-breaking membrane structure 30, the first end of the water-breaking membrane rib 31 is higher than the second end of the water-breaking membrane rib 31, so that the bearing area 111 and the sinking area 112 are roughly wavy, which helps to guide the flow of water droplets, reduce the residue of water droplets, and accelerate the discharge and drying effect of water droplets.

[0130] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 5 As shown, the water-breaking membrane structure 30 also includes: a water-breaking membrane column 32 and a water-guiding column 33. The water-breaking membrane column 32 is disposed at the second end of the water-breaking membrane rib 31, and the water-breaking membrane column 32 protrudes into the receiving cavity 20, that is, the water-breaking membrane column 32 protrudes towards the receiving cavity 20; the water-guiding column 33 is disposed at the second end of the water-breaking membrane rib 31, and the water-guiding column 33 protrudes from the side opposite to the receiving cavity 20. The water-breaking membrane column 32 is used to guide water droplets to the water-guiding column 33, and finally drips from the bottom of the water-guiding column 33.

[0131] In one possible implementation, along the depth direction of the receiving cavity 20, from the top to the bottom of the water-breaking film column 32, the outer diameter of the water-breaking film column 32 gradually increases. That is, the water-breaking film column 32 is conical or teardrop-shaped, meaning that the upper end of the water-breaking film column 32 is thinner and the lower end is thicker. This means that when the water-breaking film column 32 comes into contact with the water surface, its contact area decreases with increasing height. This helps the water-breaking film column 32 penetrate the water surface more deeply, thereby more effectively breaking the surface tension of the water, improving the effect of water droplet falling, and thus improving drying efficiency.

[0132] In this example, the depth direction of the accommodating cavity 20 is referenced. Figure 5 The direction indicated by the arrow Z in the middle

[0133] In one possible implementation method, refer to Figure 5 As shown, there are multiple water-breaking membrane reinforcement strips 31. The first ends of the multiple water-breaking membrane reinforcement strips 31 are connected to different inner wall surfaces of the mesh 114, and the second ends of the multiple water-breaking membrane reinforcement strips 31 intersect to form a junction 311. The multiple water-breaking membrane reinforcement strips 31 are beneficial to improving the overall structural strength of the bottom mesh 11.

[0134] This structure allows water droplets to be guided from multiple directions, converging them at the junction 311 to form larger droplets. This improves the efficiency of water droplet collection or discharge and promotes rapid water discharge.

[0135] In one possible implementation, both the water-breaking film column 32 and the water-guiding column 33 are located at the confluence 311.

[0136] In one possible implementation method, refer to Figure 1 , Figure 2 and Figure 4 As shown, the top of the water-breaking film rib 31 narrows, which helps to reduce the flow resistance of water droplets on the water-breaking film rib 31, reduce the residence time of liquid on the rib, guide water droplets to flow downward more quickly, and concentrate them at the confluence 311, thereby improving the water droplet aggregation efficiency.

[0137] In one possible implementation method, refer to Figure 1 and Figure 5 As shown, the pallet assembly also includes at least one limiting rib plate 40, which is disposed within the receiving cavity 20. The top of the limiting rib plate 40 is provided with multiple limiting grooves 41, which are spaced apart along the width direction of the bottom mesh 11. The width direction of the bottom mesh 11 is referenced... Figure 1 The direction indicated by the arrow Y in the diagram is also the width direction of the tray assembly.

[0138] In one possible implementation, the two ends of the limiting rib plate 40 are respectively connected to the inner walls of opposite sides of the receiving cavity 20, and the bottom end of the limiting rib plate 40 is connected to the bottom mesh 11, so that the limiting rib plate 40 is stably fixed in the receiving cavity 20.

[0139] In one possible implementation method, refer to Figure 1 and Figure 10 As shown, the limiting groove 41 can be an arc-shaped groove or a rectangular groove. After the chopsticks 71 are placed in the receiving cavity 20, the limiting groove 41 plays a limiting role for the chopsticks 71, which can prevent the chopsticks 71 from moving during the washing process and keep the chopsticks 71 stable.

[0140] In one possible implementation, the limiting rib 40 can be elongated, with its top end higher than the top end of the water-breaking rib 31. The top end of the limiting rib 40 is also higher than the top end of the separating rib 113, ensuring the limiting rib 40 effectively limits the movement of the chopsticks 71.

[0141] In one possible implementation method, refer to Figure 1 As shown, the enclosure 12 includes a first side wall 121, a second side wall 122, a third side wall 123 and a fourth side wall 124, wherein the first side wall 121 and the second side wall 122 are respectively connected to the two ends of the bottom mesh 11 in the width direction, and the third side wall 123 and the fourth side wall 124 are respectively connected to the two ends of the bottom mesh 11 in the length direction.

[0142] refer to Figure 5 and Figure 6 As shown, the top of the first sidewall 121 is provided with an anti-detachment boss 125, and the outer wall surface of the first sidewall 121 is provided with an installation structure 50, which is used to install the pallet assembly onto the shelf assembly 60.

[0143] From the end of the second sidewall 122 connected to the bottom mesh 11 to the end of the second sidewall 122 away from the bottom mesh 11, the second sidewall 122 gradually slopes away from the receiving cavity 20. This structure makes the second sidewall 122 inclined, which helps to increase the opening area of ​​the receiving cavity 20 on the side near the second sidewall 122, making it easier to pick up and place the chopsticks 71.

[0144] The anti-detachment boss 125 is a protruding structure that protrudes from the top of the first side wall 121. When the tray assembly tilts, the anti-detachment boss 125 can effectively prevent the chopsticks 71 from rolling down and detaching from the receiving cavity 20.

[0145] In one possible implementation, the mounting structure 50 includes a fastening element 51 and a support portion 57 disposed on the outer wall surface of the first sidewall 121.

[0146] In one possible implementation method, refer to Figure 6 , Figure 7 and Figure 8 As shown, the mounting structure 50 includes: at least two fastening members 51, a first slot 54 is formed between the fastening members 51 and the outer wall surface of the first side wall 121, the first slot 54 has an opening facing the bottom mesh 11, a second slot 55 is provided in at least one fastening member 51, a horizontal bar 611 is engaged in the first slot 54, and a vertical bar 612 is engaged in the second slot 55; a support part 57 abuts against the side of the horizontal bar 611 facing the opening of the first slot 54.

[0147] In one possible implementation, the mounting structure 50 is symmetrical about the center plane of the bottom mesh 11 along its length, allowing the tray assembly to be freely placed on both sides of the basket, thus improving the versatility of the tray assembly.

[0148] In one possible implementation, the surface of the base mesh 11 may also be coated with a hydrophobic coating to improve the drying effect.

[0149] refer to Figure 11 As shown, the shelf assembly 60 includes a mounting portion 61, with horizontal bars 611 and vertical bars 612 arranged alternately within the mounting portion 61. There can be multiple horizontal bars 611 and multiple vertical bars 612, with the multiple vertical bars 612 arranged at intervals. The shelf assembly 60 also includes a shelf body 62, which has a storage cavity for accommodating tableware such as bowls and plates. The mounting portion 61 can be connected to the top of one side wall of the shelf body 62, or it can be formed by one side wall of the shelf body 62.

[0151] In one possible implementation, the dishwasher body 70 includes at least one shelf assembly 60, which includes mounting portions 61, and horizontal bars 611 and vertical bars 612 arranged alternately on the mounting portions 61. Other structures of the dishwasher body 70 refer to existing structures and will not be described in detail here.

[0152] In one possible implementation, a first slot 54 is formed between the first fastener 51 and the outer wall surface of the first sidewall 121. The opening of the first slot 54 faces downward. When the pallet assembly is installed on the shelf assembly 60, the crossbar 611 is located in the first slot 54, and the support part 57 is supported on the lower side of the crossbar 611. The upper and lower limits of the pallet assembly are realized by the support part 57, the first fastener 51 and the second fastener 52.

[0153] In one possible implementation, a second slot 55 is also provided in the first fastening member 51. The second slot 55 connects the first slot 54 and the side of the fastening member 51 facing away from the first side wall 121. When the tray assembly is installed on the shelf assembly 60, the top of the vertical rod 612 is located in the second slot 55, thereby limiting the length of the tray assembly.

[0154] In one possible implementation, the dishwasher body 70 includes two shelf assemblies 60, namely an upper shelf assembly and a lower shelf assembly. The aforementioned tray assembly may be installed on the upper shelf assembly or on the lower shelf assembly.
