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

[0058] like Figures 1 to 9 As shown, a dishwasher liner assembly of an embodiment of the utility model comprises: an liner body 1, a rear crossbeam 2, a connecting plate 3 and a chassis 4. The rear crossbeam 2 is connected to the rear side of the top of the liner body 1; the chassis 4 is connected to the bottom of the liner body 1; the top of the connecting plate 3 is connected to the rear crossbeam 2, the middle of the connecting plate 3 is connected to the rear side of the middle of the liner body 1, and the bottom of the connecting plate 3 is connected to the chassis 4.

[0059] Among them, the inner tank body 1 is one of the core components of the dishwasher, usually made of stainless steel because of its good corrosion resistance, high temperature resistance and easy cleaning characteristics. It is a container that holds and directly contacts tableware, designed to carry bowls, plates, cups, spoons and other types of tableware. During the operation of the dishwasher, the tableware is placed in this area to be cleaned by the spray water flow. The structural design of the inner tank body 1 must ensure sufficient space and reasonable layout so that tableware of various sizes and shapes can be properly placed and effectively cleaned and dried. In addition, the shape and size of the inner tank body 1 directly affect the capacity and dishwashing efficiency of the dishwasher.

[0060] As an important supporting component in the structure of the dishwasher, the rear crossbeam 2 is mainly installed on the top rear side of the inner tank body 1 to support and reinforce the inner tank assembly. In some designs, the rear crossbeam 2 may also be integrated with a circuit board or water pipes to support the electrical control and water supply and drainage system of the dishwasher. The rear crossbeam 2 is usually made of high-strength metal materials, such as stainless steel or anti-corrosion treated steel, to ensure sufficient load-bearing capacity and durability to prevent deformation or rust during long-term use.

[0061] The chassis 4 is the bottom support structure of the dishwasher, and is usually made of stainless steel or other corrosion-resistant materials. It not only provides a bottom support platform for the dishwasher, but also serves as the installation base for the entire machine. The chassis 4 is closely connected to the bottom of the inner tank body 1, serving as a solid base for the inner tank body 1. The design of the chassis 4 must take into account the convenience of waterproofing and drainage to ensure that the waste water generated during the dishwashing process can be discharged smoothly. At the same time, it is also necessary to ensure the overall stability of the dishwasher to avoid shaking during operation. In some designs, the chassis 4 may also be integrated with a filter or other cleaning auxiliary device to filter out impurities such as food residues during the washing process.

[0062] The connecting plate 3 is a key innovative design in this embodiment. It realizes the integrated fixation between these components by connecting with the inner tank body 1, the rear cross beam 2 and the chassis 4. The connecting plate 3 may be composed of multiple sub-plates to jointly construct a stable support structure. A reinforcement structure may also be provided on the connecting plate 3 to further improve the torsion resistance and overall rigidity. The connecting plate 3 can be accurately fixed to the inner tank body 1, the rear cross beam 2 and the chassis 4 by means of screws, trapezoidal limit grooves 5, connecting holes, etc., to ensure that the inner tank assembly of the dishwasher is stable and reliable during use, and to avoid deformation due to force affecting the dishwashing effect.

[0063] Specifically, the connecting plate 3 includes an inner liner body connecting portion 36, a rear cross beam connecting portion 30 and a chassis connecting portion 38; the rear cross beam connecting portion 30 is strip-shaped and extends vertically, and the top is connected to the rear cross beam 2; the inner liner body connecting portion 36 is sheet-shaped, arranged on one side of the rear cross beam connecting portion 30, and connected to the inner liner body 1; the chassis connecting portion 38 is sheet-shaped, arranged at the bottom of the other side of the rear cross beam connecting portion 30, and connected to the chassis 4.

[0064] Among them, the rear cross beam connection part 30 includes a first connection plate 31, a second connection plate 32, a third connection plate 33 and an end plate 34; one side of the second connection plate 32 is connected to one side of the first connection plate 31, and the other side of the second connection plate 32 is connected to one side of the third connection plate 33, so that the end face of the rear cross beam connection part 30 is trapezoidal; the end plate 34 connects the top ends of the first connection plate 31, the second connection plate 32 and the third connection plate 33.

[0065] The first connecting plate 31 , the second connecting plate 32 , and the third connecting plate 33 are well-designed flat plate structures, and they may be connected to each other by welding, screw fixing, or other reliable connection methods.

[0066] Although the first connecting plate 31, the second connecting plate 32, and the third connecting plate 33 are described as independent parts that together constitute the overall structure of the connecting plate 3, in fact, they may also be processed by a single plate through a stamping process. This design method allows the required multi-part structure to be formed on a plate through a one-time stamping of a mold, including different connecting plate 3 segments and possible reinforcing ribs, grooves and other structures. The specific steps may include:

[0067] Design and mold making: First, according to the final design requirements of the connecting plate 3, a stamping die including the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33 is designed. The mold design needs to accurately match the size and connection relationship of each part to ensure that it can be accurately spliced ​​into a trapezoidal structure after one-time molding.

[0068] Plate preparation: Select appropriate metal plates, usually stainless steel or alloy materials with a certain strength and toughness, and cut them according to the required size.

[0069] Stamping: The prepared sheet is placed in a stamping machine. Through the pressing action of the mold, the sheet undergoes steps such as stretching, bending, and cutting to form a predetermined shape, which includes the first connecting plate 31, the second connecting plate 32, the third connecting plate 33, and possible reinforcement structures. In this process, different areas of the sheet will be pressed into different heights and shapes according to the design, thereby realizing a continuous or segmented structure of multiple connecting plates 3 on a sheet.

[0070] Subsequent processing: After stamping is completed, trimming, deburring, surface treatment and other processes may be required to ensure that the edge of the connecting plate 3 is smooth and has no sharp corners, and to improve its corrosion resistance and aesthetics.

[0071] The connecting plate 3 produced in this way, although physically formed by a continuous plate, still maintains the respective roles and advantages of multiple sub-plates in terms of structural design and function. For example, one side of the second connecting plate 32 is connected to one side of the first connecting plate 31, and the other side is connected to one side of the third connecting plate 33, maintaining the trapezoidal structure of the end surface, while maintaining the overall fit and support effect with the rear side of the liner body 1. This design not only saves materials and simplifies the assembly process, but also ensures the strength and stability of the structure.

[0072] One side of the second connecting plate 32 is adjacent to and connected to one side of the first connecting plate 31, and the other side thereof is connected to one side of the third connecting plate 33. The first connecting plate 31, the third connecting plate 33 and the second connecting plate 32 are not perpendicular, but are at an obtuse angle to each other, forming a groove structure, so that the end surface of the connecting plate 3 is a trapezoidal groove. This design is conducive to distributing the load in the vertical direction, especially when the connecting plate 3 is connected to the rear cross beam 2 and the chassis 4, it can better disperse and transmit the weight and torsion from the liner assembly.

[0073] This shape can also make the connecting plate 3 fit more closely with the rear edge of the inner liner body 1. Such a design not only increases the contact area between the connecting plate 3 and the inner liner body 1, but also can evenly distribute the pressure along the vertical direction of the inner liner body 1, thereby improving the overall stability.

[0074] The end plate 34 is located at the top of the connecting plate 3, and serves as the top seal of the connecting plate 3, connecting the tops of the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33 to form a closed top boundary. The existence of the end plate 34 not only increases the overall rigidity of the connecting plate 3, ensures the stability and consistency between the first connecting plate 31, the second connecting plate 32 and the third connecting plate 33, and prevents separation or dislocation when subjected to external forces, but also can be closely docked with the rear cross beam 2, ensuring the precise positioning of the entire connecting plate 3 system in the vertical direction.

[0075] In one embodiment, a trapezoidal limiting groove 5 is provided on the rear cross beam 2, and a first connecting hole 6 is provided at the bottom of the trapezoidal limiting groove 5; a second connecting hole 35 is provided at the end plate 34; the top of the connecting plate 3 is inserted into the trapezoidal limiting groove 5, and a fastener is passed through the first connecting hole 6 and the second connecting hole 35 in sequence to connect the top of the connecting plate 3 to the rear cross beam 2.

[0076] Trapezoidal limiting grooves 5 are respectively provided at both ends of the rear cross beam 2. The main function of the trapezoidal limiting grooves 5 is to receive the top of the connecting plate 3, thereby ensuring that the connecting plate 3 can be accurately aligned and firmly installed on the rear cross beam 2. The bottom of the trapezoidal limiting grooves 5 is also provided with first connecting holes 6, which are designed for fasteners such as screws to pass through, so as to achieve mechanical connection between the connecting plate 3 and the rear cross beam 2.

[0077] The end plate 34 is provided with a second connection hole 35 corresponding to the first connection hole 6 on the rear cross beam 2, providing a path for the fastener to pass through.

[0078] The top of the connecting plate 3 is designed to be inserted into the trapezoidal limiting groove 5 on the rear cross beam 2. After being correctly inserted, fasteners such as bolts and nuts will pass through the first connecting hole 6 on the rear cross beam 2 and the second connecting hole 35 on the end plate 34 in sequence, and finally these fasteners are tightened to achieve a tight connection between the top of the connecting plate 3 and the rear cross beam 2. This process not only ensures the firmness of the connection, but also increases the overall torsion resistance of the structure.

[0079] In one embodiment, the liner body connection part 36 is formed by extending from one side of the rear cross beam connection part 30 in a direction away from the rear cross beam connection part 30; the liner body connection part 36 is abutted and connected to the rear side of the side wall of the liner body 1. The liner body connection part 36 can be used as a reinforcing anti-torsion plate.

[0080] The liner body connection part 36 is formed by extending outward from one side of the third connecting plate 33. This means that the liner body connection part 36 is integrated with the third connecting plate 33. Through this design, the torsion resistance of the connecting plate 3 can be enhanced without significantly increasing the complexity of the structure without additional components.

[0081] The inner tank body connection part 36 can enhance the strength and torsion resistance of the connection plate 3 in the vertical direction, especially for the problem of deformation of the middle position that may be caused by uneven distribution of the gravity of the tableware when the dishwasher is running. By connecting the inner tank body connection part 36 to the rear side of the middle part of the inner tank body 1, the support of the inner tank assembly in the height direction is increased, so that the inner tank assembly is not easily twisted and deformed when subjected to vertical pressure, thereby ensuring the long-term stability and durability of the dishwasher.

[0082] The inner tank body connecting portion 36 is kept parallel to the second connecting plate 32. The parallel arrangement helps to maintain the overall balance of the inner tank assembly of the dishwasher during the fixing and supporting process, and reduces the potential risks caused by uneven force.

[0083] In summary, the design of the inner tank body connection part 36 is a structural optimization strategy. It enhances the overall structural stability of the dishwasher inner tank assembly through clever structural layout and material extension, effectively solves the problem of easy deformation of the inner tank assembly in traditional design, and provides users with a more efficient and durable dishwasher product.

[0084] When designing the inner container body connection part 36, precise mounting holes are specially preset thereon to ensure a stable and precise connection with the inner container body 1. The connection process is specifically unfolded as follows:

[0085] First, the position of the mounting holes of the liner body connection part 36 is planned in advance according to the specific structure and design requirements of the rear side of the liner body 1. These reserved mounting holes are precisely aligned with the corresponding mounting positions or fixing points on the liner body 1 to ensure that they can fit tightly and without deviation during connection.

[0086] The rear side of the middle of the liner body 1 is also provided with corresponding mounting holes, which correspond one-to-one with the reserved holes on the liner body connecting portion 36, ensuring that the fasteners can pass through smoothly and realize the effective connection between the two components.

[0087] Using fasteners such as screws and bolts, starting from the reserved hole on one side of the inner liner body connection part 36, through the corresponding hole on the inner liner body 1, and then with nuts or other fixing elements such as washers, spring washers, etc., to fasten on the other side of the inner liner body 1. This process requires ensuring that the tightening force is moderate, both to ensure the firmness of the connection and to prevent deformation or damage of the material caused by over-tightening.

[0088] In order to ensure the reliability of the connection during long-term use, measures such as anti-loosening nuts, applying thread glue, or using self-locking nuts may be adopted to prevent loosening caused by vibration or long-term use when the dishwasher is working.

[0089] Through the above method, a stable mechanical connection is formed between the inner tank body connection part 36 and the inner tank body 1. This connection can not only effectively improve the torsional resistance of the inner tank assembly, but also enhance its overall rigidity and load-bearing capacity, ensuring that the dishwasher maintains structural stability and safety during long-term use.

[0090] It also includes a plurality of first reinforcing protrusions 37; the first reinforcing protrusions 37 are arranged on the inner tank body connection part 36 and the rear cross beam connection part 30, and the plurality of first reinforcing protrusions 37 are arranged at intervals along the length direction of the rear cross beam connection part 30. The first reinforcing protrusions 37 are usually arranged at key stress points or weak areas of the connecting plate 3, such as the central area of ​​the connecting plate 3, the transition area connecting the inner tank body 1, etc. These positions are subjected to greater stress during the operation of the dishwasher and are prone to become the starting point of deformation. The position layout of the first reinforcing protrusions 37 needs to comprehensively consider the stress analysis of the connecting plate 3 and the balance of the overall structure. They may be evenly distributed in high stress areas to achieve local or overall reinforcement.

[0091] The number of the first reinforcing protrusions 37 depends on the size, material strength and expected load conditions of the connecting plate 3. The reasonable setting of the number is usually determined through mechanical analysis and experimental verification.

[0092] During the production process, the first reinforcing protrusion 37 can be formed directly on the connecting plate 3 by a stamping process. This process can quickly and efficiently form the required protrusion shape on the plate, and is suitable for mass production. For reinforcing protrusions that require higher strength or complex shapes, casting or forging processes may be used. Although these two processes are more expensive, they can provide better mechanical properties and more complex geometric shapes.

[0093] In some cases, the first reinforcing protrusion 37 can be fixed to the connecting plate 3 as an independent component by welding or high-strength adhesive. This method has high flexibility and is suitable for small batch or customized production.

[0094] In another embodiment, the chassis connection portion 38 is a plate-shaped structure formed by extending from the bottom of one side of the second connection plate 32 away from the rear cross beam connection portion 30 ; the chassis connection portion 38 is connected to the chassis 4 .

[0095] The chassis connection portion 38 is not an independent component, but is formed as a part of the connection plate 3 by extending outward from the bottom of one side of the second connection plate 32. Such a design enables the chassis connection portion 38 to make full use of the existing structural layout and achieve effective connection with the chassis 4 without adding additional installation complexity.

[0096] The connection between the chassis connection part 38 and the chassis 4 is achieved by screws, bolts or other types of fasteners. These fasteners tightly fix the chassis connection part 38 and the chassis 4 together through preset threaded holes or fixing points to ensure that there is no risk of slippage or looseness between the two. This connection method not only enhances the stability of the connection, but also facilitates assembly and maintenance. The connection between the chassis connection part 38 and the chassis 4 not only enhances the supporting force of the connecting plate 3 in the vertical direction, but also improves the anti-torsion performance of the entire liner assembly. During the operation of the dishwasher, when a large amount of tableware is loaded inside the liner and subjected to the impact of water flow, the presence of the chassis connection part 38 can effectively disperse these forces, reduce the possibility of deformation of the liner assembly, and extend the service life of the dishwasher.

[0097] In another embodiment, it also includes a first inner liner support frame 7; a notch is provided on one side of the bottom of the connecting plate 3 close to the inner liner body 1, and the first inner liner support frame 7 covers the notch, one side of the first inner liner support frame 7 is connected to the bottom of the connecting plate 3, and the other side of the first inner liner support frame 7 is connected to the rear end of the bottom of the inner liner body 1; the bottom of the first inner liner support frame 7 is connected to the rear end of the chassis 4.

[0098] The first inner pot support frame 7 is located between the bottom of the inner pot body 1 and the bottom plate 4, with its top connected to the bottom of the connecting plate 3 and the rear end of the bottom of the inner pot body 1, and the bottom of the support frame connected to the rear end of the bottom plate 4. Such a layout design ensures that the first inner pot support frame 7 can directly participate in bearing and distributing the load of the inner pot assembly in the vertical direction, especially at the middle height position where the gravity of the tableware is concentrated, effectively avoiding the problem of deformation of the inner pot.

[0099] The setting of the first inner tank support frame 7 can be regarded as a supplement to the original support system of the connecting plate 3 and the rear cross beam 2. Especially at the rear and bottom of the dishwasher, the first inner tank support frame 7 can distribute the weight and stress more evenly and reduce local overload.

[0100] The first liner support frame 7 can be connected to the liner body 1, the connecting plate 3 and the chassis 4 by bolt fixing or other reliable detachable connection methods. The design of the first liner support frame 7 makes the installation and maintenance of the liner assembly more convenient. If the liner assembly needs to be repaired or replaced, the fixing method of the first liner support frame 7 can be quickly released and reinstalled without affecting other components, simplifying the service process.

[0101] Specifically, the first inner liner support frame 7 includes an inner liner fixing portion 71 and a connecting fixing portion 72 that are connected to each other; the inner liner fixing portion 71 is a flat plate structure and is connected and fixed to the rear end of the bottom of the inner liner body 1; the connecting fixing portion 72 is an L-shaped sheet structure; one side of the connecting fixing portion 72 is fixedly connected to one side of the inner liner fixing portion 71, and the top of the other side of the connecting fixing portion 72 is connected to the bottom of the connecting plate 3, and the bottom is connected to the rear end of the chassis 4.

[0102] The first liner support frame 7 adopts a segmented design, consisting of two key parts: an liner fixing portion 71 and a connecting fixing portion 72. This design enables the first liner support frame 7 to better adapt to the complex interface between the liner body 1, the connecting plate 3 and the chassis 4, and achieves stable connection and support.

[0103] The inner tank fixing portion 71 is directly connected to the bottom of the inner tank body 1, and a tight and firm connection is ensured by screws or other fixing methods. This design not only provides direct support to prevent the inner tank body 1 from sagging or deforming due to the gravity of the dishes when the dishwasher is working, but also helps to disperse the vertical pressure on the inner tank body 1 and improve the overall structural stability.

[0104] The connecting and fixing part 72 plays the role of a bridge, with its top connected to the bottom of the connecting plate 3 and its bottom fixed to the bottom plate 4, thus forming a continuous support path from the bottom of the liner body 1 to the bottom plate 4. This connection method enables the first liner support frame 7 to more efficiently conduct and disperse various forces borne by the liner assembly, including but not limited to gravity, torsion and impact force, thereby preventing the liner assembly from displacement or deformation during use.

[0105] Through the cooperation between the inner tank fixing part 71 and the connecting fixing part 72, the first inner tank support frame 7 can significantly improve the strength and overall torsion resistance of the inner tank assembly in the height direction, while ensuring the stability and noise control of the dishwasher during operation. Such a design optimizes the performance of the dishwasher, extends its service life, and improves the user experience.

[0106] The first liner support frame 7 itself may be designed with reinforcing ribs or a specific geometric shape to enhance its own compression and torsion resistance to ensure that it is not easily fatigued and damaged during long-term use.

[0107] The first inner tank support frame 7 is usually composed of one or more flat plate materials, and is designed with precise geometric shapes and dimensions to adapt to the specific structure and installation requirements of the dishwasher inner tank. The basic shape of the first inner tank support frame 7 and the necessary interface holes are precisely cut from the flat plate material. The cut flat plate material is bent by a CNC bending machine to form the required three-dimensional structure, such as folded edges.

[0108] The liner fixing portion 71 and the connection fixing portion 72 can also be connected by welding to form a whole. The welding process can ensure the strength and sealing of the connection.

[0109] In another embodiment, a second reinforcing protrusion 73 is further included; the second reinforcing protrusion 73 is disposed on the inner liner fixing portion 71 and / or the connecting fixing portion 72 .

[0110] The second reinforcing protrusion 73 is an element designed to further enhance the structural stability and torsion resistance. Specifically, the second reinforcing protrusion 73 is designed and arranged on the inner liner fixing portion 71 and / or the connecting fixing portion 72 of the first inner liner support frame. The number of the second reinforcing protrusions 73 can be multiple and arranged at intervals. The functions and effects of the second reinforcing protrusions 73 are as follows:

[0111] Enhanced local strength: The second reinforcing protrusion 73 can significantly enhance the local strength of the inner liner fixing portion 71 and the connecting fixing portion 72 by increasing the local thickness of the material or changing the structural shape, so that they are not easily deformed or damaged when subjected to load or torsion.

[0112] Improved torsional performance: By adding a second reinforcing protrusion 73 at the key stress point, the stress can be effectively dispersed and transferred, reducing local stress concentration, thereby improving the torsional performance of the entire inner tank support frame and ensuring the stability and safety of the inner tank assembly during the operation of the dishwasher.

[0113] Structural optimization: The design of the second reinforcing protrusion 73 may take into account the symmetry and geometric optimization of the structure, ensuring that it not only enhances the structural strength but also maintains the beauty and coordination of the overall design.

[0114] Processing technology: The second reinforcing protrusion 73 can be integrally formed or post-processed with the inner liner fixing part 71 and the connecting fixing part 72 through processes such as stamping, casting, welding or 3D printing. The specific process selection depends on factors such as material properties, cost control and production efficiency.

[0115] Position strategy: The position selection of the second reinforcing protrusion 73 is very important. Usually, it is set at the location that needs reinforcement the most based on stress analysis and actual stress conditions to achieve the maximum benefit of structural reinforcement.

[0116] In addition, it also includes a second inner liner support frame 8; the top of the second inner liner support frame 8 is connected to the front end of the bottom of the inner liner body 1; the bottom of the second inner liner support frame 8 is connected to the front end of the chassis 4.

[0117] The second inner container support frame 8 corresponds to the first inner container support frame 7, and is located at the front end of the inner container body 1, with the top connected to the front end of the bottom of the inner container body 1, and the bottom connected to the front end of the chassis 4. Such a layout provides strong support for the inner container body 1 at both ends, ensuring the stability of the entire inner container assembly when the dishwasher is working, especially when a large number of tableware with heavy front and light back is loaded, which can effectively prevent the front end of the inner container from sinking or deforming.

[0118] The second liner support frame 8 is usually also designed with a plate-like structure, and its shape and size are customized according to the specific structure and load-bearing requirements of the front end of the liner, and may include a reinforced protrusion, folded edge or other structural reinforcement design to improve its compression and torsion resistance. In terms of material, corrosion-resistant and high-strength materials such as stainless steel or aluminum alloy are also selected to ensure reliability and durability for long-term use.

[0119] The second liner support frame 8 may be connected to the liner body 1 and the chassis 4 by screws or by specially designed buckles, mortise and tenon structures, etc., to ensure a stable connection and facilitate installation and maintenance. The connection points are usually designed with anti-loosening measures, such as spring washers or thread locking glue, to prevent the vibration during the operation of the dishwasher from causing the connection to loosen.

[0120] By adding the second inner tank support frame 8 at the front end, the overall structural strength of the inner tank assembly of the dishwasher can be significantly improved, especially the risk of deformation caused by the gravity of the front tableware can be resisted. It can also help disperse the force on the bottom of the inner tank, reduce the single point load, extend the service life of the dishwasher, and improve the dishwashing efficiency and cleaning effect.

[0121] The convenience of installation is usually taken into consideration in the design. The installation of the second inner tank support frame 8 may be coordinated with the assembly steps of the inner tank body 1 and the chassis 4 to ensure that the assembly process of the entire dishwasher is fast and easy, reducing production costs and maintenance difficulties.
