The above schematic diagram is not intended to be an actual scale of an actual product.

[0055] like Figures 1 to 6 As shown, a tableware storage rack for a dishwasher according to an embodiment of the utility model comprises: a first tray 1 and a second tray 2 .

[0056] The first tray 1 includes a rectangular box body with an open top, and the upper surface of the bottom of the rectangular box body is covered with vertical protrusions 4 and drainage holes, and these vertical protrusions 4 play a role of separation. Multiple vertical protrusions 4 are distributed in a matrix form, so that tableware accommodating positions are formed between two adjacent rows of vertical protrusions 4 to ensure that there is an appropriate spacing between the tableware, ensuring that the long tableware such as chopsticks placed therein will not touch each other, avoiding cross contamination and accumulation during washing.

[0057] At least two clips 3 are provided at one end of the first tray 1, which are used to connect with the dishwasher basket 9 to achieve fast, tool-free installation and removal, ensuring that the tray assembly is firmly fixed to the basket 9 and can maintain a stable position even in strong water flow and vibration.

[0058] The second tray 2 includes a rectangular frame, the size of which is consistent with the rectangular box body of the first tray 1. A partition is horizontally arranged inside the rectangular frame, and the partition divides the rectangular frame into an upper and lower part, similar to the structure formed by the bottoms of two rectangular boxes fitting together. Drain holes are arranged on the partition. The upper and lower surfaces of the partition are covered with vertical protrusions 4, which serve as partitions. Tableware accommodating positions are formed on the upper and lower surfaces of the second tray 2. The structure and arrangement of the vertical protrusions 4 in the second tray 2 are consistent with those in the first tray 1, and will not be repeated here.

[0059] The other end of the first tray 1 (away from the end where the buckle 3 is provided) is rotatably connected to one end of the second tray 2 .

[0060] When in use, the buckle 3 is engaged with the frame of the bowl basket 9, and the buckle 3 can be turned around the frame of the bowl basket 9. The first tray 1 and the second tray 2 cooperate with each other in structure, and the bottom edge of their side walls cleverly supports the top frame of the frame of the bowl basket 9, which ensures that during the operation of the dishwasher, even in the face of strong impact of water flow and machine vibration, the tray can still remain fixed to prevent the tableware from sliding or shifting.

[0061] When the user needs to use two trays at the same time, he only needs to unfold the second tray 2. At this time, the upper surfaces of the first tray 1 and the second tray 2 can be used to place tableware. For example, long tableware such as chopsticks and spoons can be placed in the dedicated tableware storage positions on the first tray 1 and the second tray 2. These tableware storage positions are designed with vertical protrusions 4 and partitions to ensure that the tableware will not collide with each other, thereby maintaining a good cleaning effect.

[0062] When the number of dishes to be washed is small, or more space is needed to place larger dishes, the second tray 2 demonstrates its design flexibility. The user can flip the second tray 2 upward so that the surface originally located at the bottom is flipped to the top. At this time, the bottom of the second tray 2 becomes the upper surface, which can be used to place long dishes such as chopsticks. The upper space of the bowl basket 9 originally occupied by the second tray 2 is released, and the corresponding position of the bowl basket 9 is used to place higher dishes to be washed. This design makes full use of the internal space of the dishwasher and maintains the high efficiency of the cleaning effect.

[0063] The user can flexibly adjust the layout of the first tray 1 and the second tray 2 according to actual needs. Whether it is the quick cleaning of a small amount of daily tableware or the processing of a large number of large individual tableware, it can be easily handled, thereby maximizing the use of the internal space of the dishwasher and optimizing the cleaning efficiency.

[0064] In one embodiment, a partition plate 5 is further included; the partition plate 5 is arranged on the upper surface of the first tray 1 and the upper surface and lower surface of the second tray 2, and is used to separate two adjacent tableware storage positions in the vertical direction. The partition plate 5 arranged on the first tray 1 is equivalent to dividing the rectangular box body of the first tray 1 into two independent parts, and the two partition plates 5 arranged on the second tray 2 can respectively divide the upper part of the second tray 2 into two independent parts and the lower part of the second tray 2 into two independent parts.

[0065] Since the vertical protrusion 4 can fully separate the chopsticks and other tableware placed horizontally, it cannot ensure that the tableware placed vertically will not touch each other. Therefore, a partition plate 5 is provided in the middle of the first tray 1 and the second tray 2. Through the vertical protrusion 4 and the partition plate 5, each tableware receiving position is limited to only one tableware, and any two adjacent tableware will not touch each other during the washing process.

[0066] Considering that the dishwasher will experience high temperature and hot and humid environment during operation, the first tray 1 and the second tray 2 are usually made of plastic materials with good high temperature resistance, corrosion resistance and aging resistance, such as polypropylene PP or polycarbonate PC. These materials can not only withstand the high temperature drying process of the dishwasher, but also are not easy to deform, have good chemical stability, and are suitable for contact with food. For the first tray 1 and the second tray 2 made of plastic, the most commonly used manufacturing process is injection molding. This process injects molten plastic into the mold, cools and solidifies it, and then takes it out to form a tray component with precise size and complex structure. This method can be mass-produced, is cost-effective, and can achieve precise detail design, such as the first connection hole 7, the second connection hole 8, the vertical protrusion 4 and the partition. The buckle 3, the vertical protrusion 4 and the partition are integrally formed with the first tray 1 and / or the second tray 2.

[0067] For some high-end or commercial dishwashers, the first tray 1 and the second tray 2 are made of stainless steel, especially 304 or 316 stainless steel, which have excellent corrosion resistance and strength, are easy to clean and more durable. The first tray 1 and the second tray 2 made of metal may be made of a flat plate part by stamping, and then the various components are combined into a complete tray by welding technology, including the buckle 3, the vertical protrusion 4 and the partition. Stamping can quickly and efficiently produce parts with consistent shapes, while welding ensures a firm connection between the parts.

[0068] Whether it is plastic or stainless steel, after the basic forming is completed, surface treatment may be performed, such as sandblasting, electroplating or spraying food-grade coating to increase the corrosion resistance and surface smoothness of the tray, while also facilitating cleaning and maintenance.

[0069] In another embodiment, the buckle 3 includes a first connection portion 31, a second connection portion 32 and a hook portion 33; one end of the first connection portion 31 is fixedly connected to one end of the first tray 1; the other end of the first connection portion 31 is fixedly connected to one end of the second connection portion 32, so that the first connection portion 31 is perpendicular to the second connection portion 32; the other end of the second connection portion 32 is connected to one end of the hook portion 33, so that the second connection portion 32 is perpendicular to the hook portion 33; the first connection portion 31 and the hook portion 33 are arranged on the same side of the second connection portion 32. Preferably, the width of the hook portion 33 is smaller than the width of the first connection portion 31.

[0070] The first connection portion 31, the second connection portion 32 and the hook portion 33 form a hook structure. Since the width of the hook portion 33 is smaller than the width of the first connection portion 31, an opening is left at the free end of the hook portion 33 for inserting the frame of the bowl basket 9 through the opening to achieve a snap connection with the frame of the bowl basket 9.

[0071] For the clip 3 made of plastic, the most common processing technology is injection molding, which is injection molding together with the first tray 1.

[0072] If the buckle 3 is made of metal material (such as stainless steel), a stamping process may be used to manufacture each component, and the plate is stamped into the desired shape through a mold. For the parts that need to be connected, such as the connection between the first connecting part 31 and the second connecting part 32, spot welding, seam welding or laser welding technology may be used to ensure structural strength and stability. If the first connecting part 31, the second connecting part 32 and the hook part 33 are integrally formed, a plate needs to be stamped into the designed shape by stamping.

[0073] In some cases, the first tray 1, the second tray 2, the buckle 3, the vertical protrusion 4, the partition and the partition 5 may also adopt a composite material of plastic and metal, combining the advantages of both, such as a combination of a plastic body and a metal reinforcement, to obtain better physical properties and cost-effectiveness.

[0074] In one embodiment, a connecting rod 6 is further included; the connecting rod 6 is rotatably connected to the adjacent two ends of the first tray 1 and the second tray 2 respectively.

[0075] Specifically, there are two connecting rods 6 ; one side of the first tray 1 is rotatably connected to one side of the second tray 2 via one connecting rod 6 ; the other side of the first tray 1 is rotatably connected to the other side of the second tray 2 via another connecting rod 6 .

[0076] The connecting rod 6 includes a connecting rod body 61 and two connecting protrusions 62; the two connecting protrusions 62 are arranged at intervals on one side of the connecting rod body 61; the first connecting holes 7 are respectively arranged on one side of the first tray 1 and the second tray 2; the two connecting protrusions 62 on one connecting rod 6 are respectively plugged into the two first connecting holes 7; the second connecting holes 8 are respectively arranged on the other side of the first tray 1 and the other side of the second tray 2; the two connecting protrusions 62 on the other connecting rod 6 are respectively plugged into the two second connecting holes 8.

[0077] The connecting rod body 61 is generally a structure of a certain length, and is designed to be strong enough to bear the weight and operating force of the tray assembly during use, while ensuring smooth rotation.

[0078] Two connecting protrusions 62 are provided on one side of the connecting rod body 61, and are usually two symmetrically distributed protrusion structures. The two connecting protrusions 62 are used to precisely dock with the first connecting hole 7 and the second connecting hole 8 on the tray to achieve a rotatable connection. The size and shape of each connecting protrusion 62 must perfectly match the corresponding first connecting hole 7 and the second connecting hole 8 to ensure a stable connection and avoid disengagement or loosening during use.

[0079] The material of the connecting rod 6 is selected from high-strength engineering plastics (such as polycarbonate PC or nylon PA) or stainless steel.

[0080] The connecting rod 6 is plugged into the corresponding first connecting holes 7 and second connecting holes 8 of the first tray 1 and the second tray 2 through the connecting protrusions 62 at both ends, so that the first tray 1 and the second tray 2 can be flipped or folded around the connecting rod 6, providing users with the possibility of flexibly adjusting the spatial layout according to the number and type of tableware.

[0081] Through the design of the connecting rod 6, the user can fold or flip the second tray 2 according to actual needs, reduce the occupied space, and improve the flexibility and utilization of the internal space of the dishwasher. The variability of the tableware rack ensures that tableware of different shapes and sizes can be properly placed, especially long chopsticks and spoons, which can avoid cleaning dead corners and improve the cleaning effect. The structural design of the connecting rod 6 simplifies the installation and disassembly process of the tray assembly. The user can quickly adjust it without tools, which is convenient for daily cleaning and maintenance. The use of a simple and effective connecting rod 6 design instead of a complex mechanical structure not only reduces the manufacturing cost, but also maintains the long-term durability and reliability of the dishwasher tray assembly.
