Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dish washing equipment, and in particular to a dishwasher. BACKGROUND

[0002] In the related art, most existing dishwashers have only one washing cavity, and the volume is fixed and cannot be flexibly adjusted according to the actual number of dishes of the user. When the user needs to clean a large number of dishes, there may be insufficient space to accommodate all the dishes. When the number of dishes is small, the space is wasted, the efficiency of the dishwasher cannot be fully utilized, and the cleaning effect may be poor due to the scattered placement of the dishes. This situation makes the dishwasher unable to meet the compatible washing needs of a large number of dishes and a small number of dishes of the user, thereby resulting in poor user experience and failing to truly meet the user's needs for convenient, efficient and personalized dish cleaning.

[0070] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0071] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0072] Where the following description relates to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0073] In the description of this application, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, in the description of this application, unless otherwise stated, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship.

[0074] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0075] This application proposes a dishwasher 1 that can effectively remove food residue from the surface of tableware (bowls, plates, etc.), disinfect and sterilize the tableware during the washing process, and dry the tableware after washing and sterilization. The disinfection and sterilization are achieved by adding a cleaning solution to the water used to clean the tableware, and controlling the internal environment of the dishwasher 1 (including the water temperature of the cleaning solution) at approximately 70℃ to 85℃. At this temperature, the activity of common pathogenic microorganisms such as Escherichia coli and Staphylococcus aureus is inhibited or even killed, thus ensuring the hygiene of the tableware. The drying method of the dishwasher 1 can be heat exchange drying, hot air drying, etc., effectively preventing the tableware from growing bacteria and producing odors due to moisture.

[0076] In related technologies, dishwasher 1 is equipped with only one washing chamber, and the space of the washing chamber is fixed, which makes it impossible to flexibly adjust according to the actual number of dishes the user has. For example, when the user needs to wash a large number of dishes, it is difficult to accommodate all the dishes due to the constraints of the washing chamber space and the carrying space of the dish rack assembly. When the number of dishes is small, some space will not be utilized, and water during the washing process will still spray onto the empty areas where no dishes are placed, which not only wastes space but also fails to fully utilize the efficiency of dishwasher 1.

[0077] Based on this, this application provides a dishwasher 1, which aims to improve the utilization rate of the washing space, so as to give full play to the efficiency of the dishwasher 1 and thus meet the user's need to flexibly adjust according to the actual number of tableware.

[0078] Please refer to the specific details. Figures 1 to 11 As shown, the dishwasher 1 includes an inner tub 15 and a divider 16. The inner tub 15 has a washing cavity 153, in which tableware can be stored and cleaned, sterilized, and dried. The divider 16 is fitted into the washing cavity 153 to divide it into an upper washing cavity 1531 and a lower washing cavity 1532. By providing relatively independent upper and lower washing cavities 1531 and 1532, the dishwasher can better meet the washing needs of different quantities of tableware. When a user has a large number of tableware to wash, both the upper and lower washing cavities 1531 and 1532 can be used simultaneously, increasing the total washing space and improving space utilization, no longer limited by a single large-capacity washing cavity.

[0079] It should be noted that the size of the upper washing chamber 1531 may differ from that of the lower washing chamber 1532. For example, if the upper washing chamber 1531 is smaller than the lower washing chamber 1532, the types of tableware placed in the upper washing chamber 1531 will be different from those in the lower washing chamber 1532, allowing for a more compact arrangement of tableware. Alternatively, the upper washing chamber 1531 may be the same size as the lower washing chamber 1532. When the number of tableware is small, the user can use only one washing chamber. This avoids the space waste that occurs when a single large-capacity washing chamber is used to wash a small number of tableware. This allows for more rational use of the space in the dishwasher 1, meeting the user's needs in scenarios with different amounts of tableware and maximizing the efficiency of the dishwasher 1.

[0080] On the other hand, the independent upper washing chamber 1531 and lower washing chamber 1532 make the washing process clearer. During the washing process, the two washing chambers can work in parallel, shortening the overall washing time. Moreover, when one washing chamber malfunctions or requires maintenance, the other washing chamber can still be used normally, without affecting the user's daily dishwashing needs.

[0081] In this embodiment, please refer to the following for details. Figures 1 to 8 As shown, the aforementioned inner liner 15 includes an upper inner liner 151 and a lower inner liner 152. The upper inner liner 151 includes an upper body 1511, which has an upper inner liner top wall 15111, an upper inner liner back wall 15112, and upper inner liner side walls 15113. Two upper inner liner side walls 15113 are configured, with the two side walls 15113 arranged opposite each other and vertically connected to the upper inner liner top wall 15111, forming a U-shaped workpiece. Figure 1 and Figure 2 As shown, the top wall 15111 of the upper inner liner is preferably integrally formed with the two side walls 15113 of the upper inner liner, and the back wall 15112 of the upper inner liner is preferably integrally formed with the top wall 15111 of the upper inner liner and fixedly connected to the side walls 15113 of the upper inner liner.

[0082] This reduces the number of connection points between components, resulting in better continuity and higher overall structural strength of the upper inner tank 151. During long-term use of the dishwasher 1, it can better withstand internal water pressure and external forces such as impacts, reducing the risk of breakage, deformation, and other damage. It also helps ensure the airtightness of the upper inner tank 151, effectively preventing water leakage at the joints, thereby improving the reliability and lifespan of both the inner tank 151 and the dishwasher 1, and reducing malfunctions and repair costs caused by leaks. Simultaneously, the one-piece molding process simplifies production procedures, improves production efficiency and processing precision, and reduces labor and material costs during production. Furthermore, the smoother surface of the one-piece upper inner tank 151 reduces seams, making it less likely for food residue to accumulate in the gaps during cleaning. This not only reduces cleaning difficulty but also prevents the growth of bacteria and mold in the gaps, ensuring greater hygiene for both the dishwasher 1 and the cleaned dishes.

[0083] In addition to the methods described above, the upper inner liner back wall 15112 can also be integrally formed with one of the upper inner liner side walls 15113 and fixedly connected to the upper inner liner top wall 15111. This also ensures the overall structural strength and stability of the upper inner liner 151 and offers advantages in production technology and cost. It should be noted that the upper inner liner top wall 15111 and both upper inner liner side walls 15113 are fixedly connected to the upper inner liner back wall 15112. This connection should be understood as the upper inner liner back wall 15112, upper inner liner top wall 15111, and both upper inner liner side walls 15113 being individually formed workpieces. This facilitates precise machining and quality control of each individual workpiece and makes the production and assembly processes more flexible. During assembly, adjacent upper inner liner back walls 15112, upper inner liner top walls 15111, and two upper inner liner side walls 15113 are first interlocked and spliced, then welded or riveted, and finally sealed with adhesive. In the actual production process, taking into account factors such as production difficulty, manufacturing requirements, and production costs, the production process combines splicing and assembly with one-piece molding.

[0084] As a preferred embodiment, please refer to the following for details. Figures 1 to 8 As shown, the lower inner liner 152 includes a lower body 1521, which includes a lower inner liner bottom wall 15214, a lower inner liner top wall 15211, a lower inner liner side wall 15213, and a lower inner liner back wall 15212. The number of lower inner liner side walls 15213 is two, and the two lower inner liner side walls 15213 are arranged opposite each other and are both vertically connected to the lower inner liner top wall 15211. The lower inner liner top wall 15211 and the lower inner liner bottom wall 15214 are arranged opposite each other. Preferably, as shown... Figure 1 and Figure 2As shown, the lower inner liner top wall 15211 is integrally formed with the two lower inner liner side walls 15213, and both lower inner liner side walls 15213 are connected to the lower inner liner bottom wall 15214 to form a U-shaped workpiece. The lower inner liner back wall 15212 is integrally formed with the upper inner liner top wall 15111 and is fixedly connected to the lower inner liner bottom wall 15214 and the two lower inner liner side walls 15213.

[0085] This also ensures that the lower inner tank 152 has high overall structural strength. During long-term use of the dishwasher 1, it can better withstand the pressure of internal water and external forces such as possible impacts, reducing the risk of damage such as cracking and deformation. It also helps to ensure the sealing of the lower inner tank 152, effectively preventing the risk of water leakage from the joints, thereby further improving the reliability and service life of the inner tank 15 and the dishwasher 1, and reducing failures and maintenance costs caused by water leakage. At the same time, the one-piece molding process can also simplify the production process, improve production efficiency, and reduce labor and material costs in the production process.

[0086] In addition to the methods described below, the lower inner liner back wall 15212 can also be integrally formed with one of the lower inner liner side walls 15213, and fixedly connected to the lower inner liner top wall 15211 and the lower inner liner bottom wall 15214. This also ensures the overall structural strength and stability of the lower inner liner 152, and has advantages in production technology and cost. It should be further noted that the lower inner liner top wall 15211, the lower inner liner bottom wall 15214, and the two lower inner liner side walls 15213 are all fixedly connected to the lower inner liner back wall 15212. This connection should be understood as the lower inner liner back wall 15212, the lower inner liner top wall 15211, the lower inner liner bottom wall 15214, and the two lower inner liner side walls 15213 being individually formed workpieces. This facilitates precise machining and quality control of each individual workpiece, and also makes the production and assembly processes more flexible. During assembly, the lower inner liner back wall 15212, lower inner liner top wall 15211, lower inner liner bottom wall 15214, and two adjacent lower inner liner side walls 15213 are first interlocked and spliced, then welded or riveted, and sealed with adhesive. In the actual production process, considering factors such as production difficulty, manufacturing requirements, and production costs, splicing assembly and one-piece molding are combined in the production process.

[0087] In summary, the U-shaped upper inner tank 151 is stacked and installed on top of the U-shaped lower inner tank 152, allowing the upper and lower inner tanks 151 and 152 to be processed independently during production. Subsequent assembly of the upper and lower inner tanks 151 and 152 is sufficient to form the upper washing chamber 1531 and lower washing chamber 1532, meeting diverse user needs. This stacking installation method is relatively simple, effectively avoiding complex internal structure assembly, reducing assembly steps and difficulty, and improving production convenience and efficiency. It solves the problem of cumbersome assembly caused by the complex overall structure of existing split-chamber dishwashers 1, and the simple overall structure also helps reduce manufacturing costs.

[0088] like Figure 2 As shown, one of the two upper inner liner sidewalls 15113 is defined as the upper left sidewall, and the other as the upper right sidewall. Similarly, one of the two lower inner liner sidewalls 15213 is defined as the lower left sidewall, and the other as the lower right sidewall. The upper left sidewall and lower left sidewall are coplanar, and the upper right sidewall and lower right sidewall are also coplanar. Coplanarity here means being on the same plane; specifically, in the vertical direction, the upper left sidewall and lower left sidewall are on the same plane, and the upper right sidewall and lower right sidewall are on the same plane.

[0089] This design not only allows the upper inner tub 151 and lower inner tub 152 to better support each other at the connection point 1683, enhancing the stability and robustness of the entire inner tub 15 structure of the dishwasher 1 and reducing the possibility of deformation or damage caused by vibration during washing, but also facilitates the alignment and connection of the upper inner tub 151 and lower inner tub 152 during assembly, reducing assembly difficulty and precision requirements and improving assembly efficiency. Furthermore, it makes the side lines of the dishwasher 1 smoother and neater, improving the overall aesthetics and meeting users' aesthetic needs for product appearance design.

[0090] Of course, such as Figure 1 and Figure 2 As shown, the upper inner tank back wall 15112 and the lower inner tank back wall 15212 are preferably coplanar, which further ensures the structural strength, structural stability, and sealing of the entire dishwasher 1, and also facilitates positioning and docking during assembly, further improving the efficiency of the assembly process. In addition, it provides more regular space for the layout of other components inside the dishwasher 1, such as the heating device and drain pipes, which is conducive to optimizing the internal structural design, making the installation and arrangement of each component more reasonable, and improving the overall performance and reliability of the dishwasher 1.

[0091] Preferably, please refer to Figure 12The upper inner tank back wall 15112 and / or upper inner tank side wall 15113 are bent into an upper bent edge 15116 facing upward towards the washing chamber 1531. The upper bent edge 15116 abuts against the lower inner tank top wall 15211. Specifically, the upper bent edge 15116 is set parallel to the lower inner tank top wall 15211, so that the upper bent edge 15116 completely abuts against and fits against the lower inner tank top wall 15211. The upper bent edge 15116 is welded or glued to the lower inner tank top wall 15211. In this way, the contact area / force-bearing area between the upper inner tank 151 and the lower inner tank top wall 15211 is increased, so that the pressure can be more evenly distributed to the lower inner tank top wall 15211 through the upper bent edge 15116. To a certain extent, it can absorb and disperse the vibration energy generated during cleaning of tableware, alleviate the stress generated by vibration, and improve the stability of the dishwasher 1. Meanwhile, the upper bent edge 15116 also serves as a reinforcing structure for the edge of the upper inner tub 151. When the dishwasher 1 is subjected to external forces (such as collisions, torsional forces generated when placed on uneven surfaces, etc.), the upper bent edge 15116 can increase the overall rigidity of the upper inner tub 151 and resist deformation caused by external forces. Through its connection with the top wall 15211 of the lower inner tub, the upper bent edge 15116 transmits external forces to the entire structure of the lower inner tub 152, utilizing the structural strength of the lower inner tub 152 to jointly resist external forces, thereby protecting the structural integrity of the upper inner tub 151 and the entire dishwasher 1.

[0092] In addition, the upper bent edge 15116 is connected to the top wall 15211 of the lower inner liner and is sealed with glue or by welding, which can effectively fill the gap between the upper inner liner 151 and the lower inner liner 152, forming a good sealing structure and effectively preventing the risk of leakage between the upper inner liner 151 and the lower inner liner 152.

[0093] Further, please see Figure 12 The upper bent edge 15116 extends upwards towards the washing chamber 1531 by a length 'a', where 'a' ≥ 3mm. This ensures sufficient connection area between the upper bent edge 15116 and the top wall 15211 of the lower inner tub. Whether welding or gluing is used, a larger connection area means greater tensile and shear forces, making the connection between the upper inner tub 151 and the lower inner tub 152 more stable. It also distributes external forces more evenly over a larger area. This allows the dishwasher 1 to better resist various external forces during operation, reducing the possibility of loosening or damage to the connection 1683 due to vibration or impact. Furthermore, it better ensures the sealing of the connection between the upper inner tub 151 and the lower inner tub 152. When the upper bent edge 15116 extends longer, it better accommodates gap changes between the upper inner tub 151 and the lower inner tub 152 caused by manufacturing precision, material deformation, etc., allowing gluing or welding to more effectively fill the gaps and ensure a seal.

[0094] However, if the extension length a of the upper bend 15116 is less than 3mm, the connection area between the upper bend 15116 and the lower inner liner top wall 15211 is too small. This not only fails to ensure the structural stability and sealing effect mentioned above, but also, due to the short extension length of the upper bend 15116, the bending process may be unsmooth due to insufficient operating space, affecting the appearance and dimensional accuracy of the product.

[0095] It should be added that, for details please refer to [the relevant documentation / reference]. Figures 1 to 11 As shown, the dishwasher 1 also includes a water cup 17, which has a collection tank 171 that connects to the upper washing chamber 1531. The water cup 17 is mounted on the top wall 15211 of the lower inner tank. The collection tank 171 is used to collect the wastewater produced by the upper washing chamber 1531 and discharge it outside the upper washing chamber 1531, that is, all wastewater after washing dishes can be collected in the collection tank 171. Furthermore, a drain outlet is provided at the bottom of the collection tank 171, and the wastewater collected in the collection tank 171 will be discharged outside the upper washing chamber 1531 through the drain outlet. Preferably, a filter element 101 (such as a filter screen, filter cover, etc.) can also be installed in the collection tank 171. On the one hand, during the washing process, food residue, grease, debris and other impurities will fall into the washing water. The filter element 101 can effectively intercept these impurities and prevent them from clogging the drain pipe connected to the drain outlet or entering other parts of the dishwasher 1 with the wastewater discharge. On the other hand, the filter element 101 can promptly separate impurities generated during the washing process from the washing water, keeping the recycled washing water relatively clean. Clean washing water allows the detergent to work more effectively, improving the washing effect, preventing impurities from re-adhering to the tableware, and ensuring that the tableware is thoroughly cleaned.

[0096] Furthermore, a drain trough 164 is provided on the top wall 15211 of the lower inner liner, and a collection trough 171 is located at the bottom inner side of the drain trough 164. The drain trough 164 is used to guide sewage to the collection trough 171, so that the sewage can flow to the collection trough 171 more quickly and smoothly, preventing the risks of sewage flowing randomly, accumulating, or backflowing. Understandably, the inner bottom surface of the drain trough 164 can be an arc-shaped curved surface, or the inner bottom surface can be composed of multiple inclined planes. The collection trough 171 is located at the lowest position of the drain trough 164, thereby greatly improving drainage efficiency, reducing the residence time of sewage in the upper washing chamber 1531, and reducing the risk of secondary contamination of tableware.

[0097] To enable independent washing of tableware in the upper washing chamber 1531 and the lower washing chamber 1532, please refer to the following for details. Figures 1 to 11As shown, both the upper washing chamber 1531 and the lower washing chamber 1532 are equipped with spray devices 102. The spray device 102 installed in the upper washing chamber 1531 is defined as the first spray element, and the spray device 102 installed in the lower washing chamber 1532 is defined as the second spray element. The first and second spray elements are connected in parallel. Since the first and second spray elements can wash independently without interference, this provides users with personalized washing options. Users can set different washing programs according to the degree of soiling of the tableware. For example, the upper washing chamber 1531, containing heavily soiled plates, can select a powerful cleaning mode, while the lower washing chamber 1532, containing relatively clean cups, can select a quick cleaning mode, improving washing efficiency and targeting. Alternatively, users can operate different washing chambers at different times. It should be noted that the first and second spray elements are mature existing technologies in this field, and their specific structures and connections are not described in detail here. Furthermore, this application does not limit the number of the first and second spray elements, which can be set and adjusted according to design requirements and structural design.

[0098] In addition to the aforementioned division of the washing cavity 153 into relatively independent upper washing cavity 1531 and lower washing cavity 1532 by the lower inner liner top wall 15211 of the lower inner liner 152, the inventors have also provided another preferred embodiment, which can be referred to in conjunction with the above. Figure 3 and Figure 4 As shown, the dishwasher 1 also includes a partition 16, the aforementioned lower inner tank top wall 15211 is formed as the partition 16, that is, the lower inner tank top wall 15211 is a separately formed workpiece, and the partition 16 is provided with an upward-opening first slot 13 and a downward-opening second slot 14, both of which are preferably located near the edge of the partition 16.

[0099] Understandably, such as Figure 10 As shown, the water cup 17 is mounted on the separator 16. This not only facilitates the installation of the water cup 17, but also makes it easier to inspect, replace, and repair the water cup 17 later, reducing the difficulty and time cost of maintenance. At the same time, it also facilitates cleaning the water cup 17, maintaining the overall hygiene of the inside of the dishwasher 1.

[0100] Furthermore, such as Figure 3As shown, the upper inner liner 151 and the lower inner liner 152 are respectively located on the upper and lower sides of the separator 16. The upper inner liner 151 is provided with a first insertion part 11, and the lower inner liner 152 is provided with a second insertion part 12. The first insertion part 11 is preferably located on the back wall 15112 and / or the side wall 15113 of the upper inner liner, and the second insertion part 12 is preferably located on the back wall 15212 and / or the side wall 15213 of the lower inner liner. During assembly, the first insertion part 11 is inserted into the first slot 13, the upper inner liner 151 and the separator 16 form the upper washing chamber 1531, the second insertion part 12 is inserted into the second slot 14, and the lower inner liner 152 and the separator 16 form the lower washing chamber 1532. The upper washing chamber 1531 and the lower washing chamber 1532 are relatively independent.

[0101] This setup will have the following unexpected technical effects:

[0102] 1. The upper inner liner 151 and lower inner liner 152 are respectively inserted and assembled with the partition 16, simplifying the assembly process and reducing the difficulty of assembly and the skill requirements for workers. Compared with complex welding, riveting and other connection methods, it can also improve assembly speed and reduce assembly time and labor costs. During the assembly process or during later maintenance and replacement, the upper inner liner 151 or lower inner liner 152 can be more easily separated from the partition 16, reducing the difficulty of disassembly and maintenance, thereby reducing assembly and maintenance costs.

[0103] 2. The plug-in assembly method helps improve assembly accuracy. The first slot 13 and the second slot 14 can serve as positioning structures, guiding the upper inner tank 151 and the lower inner tank 152 to be accurately installed on both sides of the separator 16, ensuring the positional accuracy and structural stability of the upper washing chamber 1531 and the lower washing chamber 1532. This precise assembly method can reduce quality problems caused by improper assembly, such as poor sealing of the washing chamber and deviation of the spray angle of the spray device 102, thereby improving the quality stability of the product.

[0104] As a preferred embodiment, please refer to the following for details. Figure 14 As shown, the first insertion portion 11 includes a first extension 111 and a first bent portion 112 bent at the end of the first extension 111. The first extension 111 is fixedly connected to the upper inner liner back wall 15112 and / or the upper inner liner side wall 15113 of the upper inner liner 151. This fixed connection is preferably made using an integral molding process. The first extension 111 and the first bent portion 112 cooperate to form a U-shaped structure. The first extension 111 and the first bent portion 112 respectively abut against two opposite groove walls of the first slot 13, so that the first insertion portion 11 can be tightly fitted with the first slot 13.

[0105] This design significantly enhances the stability of the connection between the upper inner tub 151 and the separator 16, strengthens the insertion and ensures that the dishwasher 1 can withstand adverse factors such as washing operations and temperature changes during long-term use, reducing malfunctions caused by loose connections and preventing the upper inner tub 151 from shifting. Simultaneously, the tight contact between the first extension 111 and the first bent portion 112 and the inner wall of the first slot 13 effectively fills the gap between the slot and the insertion part, effectively preventing washing water from leaking out of the upper washing chamber 1531 and preventing food residue and other foreign objects from entering the gap between the slot and the insertion part, achieving a good sealing effect. Furthermore, the first extension 111 and the first bent portion 112 of the first insertion part 11 are formed by bending; on the production line, they can be stamped and bent using molds, facilitating processing and improving production efficiency.

[0106] Preferably, the second insertion portion 12 includes a second extension 121 and a second bent portion 122 bent at the end of the second extension 121. The second extension 121 is fixedly connected to the lower inner liner back wall 15212 and / or the lower inner liner side wall 15213 of the lower inner liner 152. This fixed connection is preferably made using an integral molding process. The second extension 121 and the second bent portion 122 cooperate to form a U-shaped structure. Both the second extension 121 and the second bent portion 122 abut against the two opposite inner groove walls of the second slot 14, so that the second insertion portion 12 can be tightly fitted with the second slot 14.

[0107] This design significantly enhances the stability of the connection between the lower inner tub 152 and the partition 16, strengthens the insertion and ensures that it can withstand adverse factors such as washing operations and temperature changes during long-term use of the dishwasher 1, reducing malfunctions caused by loose connections and preventing the lower inner tub 152 from shifting. Simultaneously, the tight contact between the second extension 121 and the second bent portion 122 and the inner wall of the second slot 14 effectively fills the gap between the slot and the insertion part. This not only effectively prevents washing water from leaking out of the lower washing chamber 1532 but also prevents food residue and other foreign objects from entering the gap between the slot and the insertion part, achieving a good sealing effect. Furthermore, the second extension 121 and the second bent portion 122 of the second insertion part 12 are formed by bending, allowing for stamping and bending operations using molds on the production line, facilitating manufacturing and improving production efficiency.

[0108] Further details are available according to... Figure 4As shown, in the first groove depth direction T1 of the first slot 13, the first bending length Lt1 of the first bending portion 112 is greater than or equal to 4 mm. That is, the first bending portion 112 is located inside the first slot 13, and the abutment height between the first bending portion 112 of the first insertion portion 11 and the first slot 13 is greater than or equal to 4 mm. At this time, the force-bearing area between the first bending portion 112 and the first slot 13 is large, which can better resist various external forces during the operation of the dishwasher 1. For example, during the placement and removal of tableware, a certain pulling or pushing force may be generated on the upper inner tank 151, or during the washing process, due to the reaction force of water spray and the shaking of tableware, the longer abutment height / larger force-bearing area can provide greater friction and support, making the connection between the upper inner tank 151 and the separator 16 more stable and reducing the risk of loosening due to external forces. Furthermore, during long-term use, sufficient contact height ensures that even if the first insertion part 11 experiences a certain degree of fatigue, the connection between the upper inner liner 151 and the partition 16 remains reliable, maintaining the normal structure and function of the upper washing chamber 1531.

[0109] Furthermore, a greater abutment height helps to form a more reliable seal. During dishwasher operation, the washing chamber is filled with a high-pressure mixture of water and detergent, which needs to be confined within the chamber. When the abutment height of the first bend 112 is sufficient, it can fit more tightly against the inner wall of the first slot 13, effectively preventing liquid leakage from the connection between the upper inner tub 151 and the separator 16. It also reduces the possibility of foreign objects (such as food residue) entering the connection gap. If the gap is too large or the abutment height is insufficient, foreign objects may be flushed into the gap during washing, affecting the seal and potentially causing blockage or corrosion. An abutment height of 4 mm or more can form a relatively deep seal, reducing this risk.

[0110] Of course, during the assembly process, when the first bending length Lt1 is greater than or equal to 4 mm, the first bending length Lt1 is relatively long and can serve as a good positioning guide structure, which facilitates positioning and calibration during the assembly process. In other words, during the insertion process, the position can be adjusted more precisely according to the contact with the inner wall of the first slot 13, which helps to improve the accuracy and efficiency of the assembly.

[0111] Conversely, when the first bend length Lt1 is less than 4 mm, the abutment height between the first bend 112 and the first slot 13 will also be less than 4 mm. This results in a small force-bearing area, which may cause the connection structure to become unstable when facing external forces during dishwasher operation, failing to provide sufficient friction and support. It also hinders the formation of a good seal. During washing, especially under higher water pressure, liquid is more likely to leak from the connection gaps. Once leakage occurs, it will not only affect the washing performance of dishwasher 1 but may also damage other electrical components, posing a safety hazard.

[0112] Preferably, in the second groove depth direction T2 of the second slot 14, the second bending length Lt2 of the second bending portion 122 is greater than or equal to 4 mm, that is, the second bending portion 122 is located inside the second slot 14, and the abutment height between the second bending portion 122 of the second insertion portion 12 and the second slot 14 is greater than or equal to 4 mm. At this time, the force-bearing area between the second bending portion 122 and the second slot 14 is large, which can better resist various external forces during the operation of the dishwasher 1, reducing the risk of loosening due to external forces. Furthermore, during long-term use, sufficient abutment height ensures that even if the second insertion portion 12 experiences a certain degree of fatigue, the connection between the lower inner tub 152 and the separator 16 remains reliable, maintaining the normal structure and function of the lower washing chamber 1532.

[0113] Furthermore, a greater abutment height helps to form a more reliable seal. During dishwasher operation, the washing chamber is filled with a high-pressure mixture of water and detergent, which needs to be confined within the chamber. When the abutment height of the second bend 122 is sufficient, it can fit more tightly against the inner wall of the second slot 14, effectively preventing liquid leakage from the connection between the lower inner tub 152 and the separator 16. It also reduces the possibility of foreign objects entering the connection gap. If the gap is too large or the abutment height is insufficient, foreign objects may be flushed into the gap during washing, affecting the seal and potentially causing blockage or corrosion. An abutment height of 4 mm or more can form a relatively deep seal, reducing this risk.

[0114] Of course, during the assembly process, when the second bending length Lt2 is greater than or equal to 4 mm, the second bending length Lt2 is relatively long and can serve as a good positioning guide structure, which facilitates positioning and calibration during the assembly process. In other words, during the insertion process, the position can be adjusted more precisely according to the contact with the inner wall of the second slot 14, which helps to improve the accuracy and efficiency of the assembly.

[0115] Conversely, when the second bend length Lt2 is less than 4 mm, the abutment height between the second bend 122 and the second slot 14 will also be less than 4 mm. This results in a small force-bearing area, which may cause the connection structure to become unstable when facing external forces during the operation of the dishwasher 1, failing to provide sufficient friction and support. It also hinders the formation of a good seal. During washing, especially under higher water pressure, liquid is more likely to leak from the connection gaps. Once leakage occurs, it will not only affect the washing performance of the dishwasher 1 but may also damage other electrical components, posing a safety hazard.

[0116] In other embodiments, the first insertion portion 11 includes a first extension 111 and a first curved portion bent at the end of the first extension 111, the first curved portion bending and protruding towards the inner wall of the first slot 13. The number of first curved portions is set and adjusted according to structural design or design requirements. The first extension 111 and the first curved portion respectively abut against the wall of the first slot 13, achieving a stable assembly and good sealing. Similarly, the second insertion portion 12 includes a second extension 121 and a second curved portion bent at the end of the second extension 121, the second curved portion bending and protruding towards the inner wall of the second slot 14. The number of second curved portions is set and adjusted according to structural design or design requirements. Both the second extension 121 and the second curved portion abut against the inner wall of the second slot 14, achieving a stable assembly and good sealing.

[0117] It should be noted that the bent portions and curved portions provided above are used in combination. For example, in the first insertion portion 11, the portion bent at the end of the first extension 111 is the first bent portion 112, and in the second insertion portion 12, the portion bent at the end of the second extension 121 is the second curved portion. As another example, in the first insertion portion 11, the portion bent at the end of the first extension 111 is the first curved portion, and in the second insertion portion 12, the portion bent at the end of the second extension 121 is the second bent portion 122. As yet another example, in the first insertion portion 11, the portion bent at the end of the first extension 111 is the first bent portion 112, and the first curved portion is bent between the first extension 111 and the first bent portion 112. Alternatively, both the first insertion portion 11 and the second insertion portion 12 can be formed as U-shaped bent portions. Of course, both the first insertion portion 11 and the second insertion portion 12 can be formed as curved portions.

[0118] As a preferred embodiment, please refer to the following for details. Figure 13As shown, the separator 16 includes a first inner sidewall 1611 and a first outer sidewall 1612. The first inner sidewall 1611 is located on the side closer to the upper washing chamber 1531, and the first outer sidewall 1612 is located on the side away from the upper washing chamber 1531 and is disposed opposite to the first inner sidewall 1611 to form a first slot 13. The height dimension of the first inner sidewall 1611 is smaller than the height dimension of the first outer sidewall 1612, that is, a height difference is formed between the first inner sidewall 1611 and the first outer sidewall 1612.

[0119] This design allows the higher first outer wall 1612 to form a relatively high blocking structure on the side away from the upper washing chamber 1531. When the dishwasher 1 is operating, even if a small amount of washing water seeps out from the connection between the first connector 11 and the first slot 13, it will be blocked by the higher first outer wall 1612, preventing it from flowing directly out of the washing chamber. Instead, it will form a relatively static water seal area within the first slot 13, further preventing water from continuing to leak outwards, thus achieving a leak-proof seal. Simultaneously, the relatively small height of the first inner wall 1611, located close to the upper washing chamber 1531, makes it easier for water to flow back into the upper washing chamber 1531 under the influence of gravity and the internal pressure of the washing chamber, rather than accumulating at the connection and causing leakage.

[0120] Furthermore, such as Figure 15 As shown, the first extension 111 abuts against the first inner wall 1611, while the first bent portion 112 abuts against the first outer wall 1612. At this time, the first extension 111 abutting against the first inner wall 1611 forms the first sealing barrier, initially preventing water from flowing into the first slot 13 through the gap between the first insertion portion 11 and the first outer wall 1612. The first bent portion 112 abutting against the first outer wall 1612 acts as the second sealing barrier. Even if a small amount of water breaches the first barrier, it will be blocked by the second barrier. Combined with the height difference between the first inner wall 1611 and the first outer wall 1612, a triple sealing barrier is formed, effectively reducing the risk of water leakage.

[0121] As a preferred embodiment, please refer to the following for details. Figure 14 and Figure 15 As shown, the aforementioned partition 16 includes a second inner sidewall 1621 and a second outer sidewall 1622, wherein the second inner sidewall 1621 is located on the side closer to the lower washing chamber 1532, and the second outer sidewall 1622 is located on the side away from the lower washing chamber 1532 and is disposed opposite to the second inner sidewall 1621 to form a second slot 14, and the height dimension of the second inner sidewall 1621 is greater than the height dimension of the second outer sidewall 1622.

[0122] This design allows the relatively high second inner wall 1621 to form a barrier near the lower washing chamber 1532. When water in the washing chamber tends to leak outward due to various reasons (such as water flow impact during washing, water splashing caused by improper placement of tableware), it will first encounter the obstruction of the second inner wall 1621. The water flow needs to overcome a certain height difference to pass over the second inner wall 1621, which increases the difficulty of water leakage and serves as a barrier. When a small amount of water seeps into the gap between the second inner wall 1621 and the second insertion part 12, under the action of gravity, the water will more easily accumulate between the second inner wall 1621 and the second insertion part 12 to form a certain water seal effect. This accumulated water can further prevent subsequent water leakage, because the water will naturally fill any gaps and channels under the action of gravity, forming a water barrier and preventing water in the washing chamber from continuing to leak outward. Therefore, the height of the second inner wall 1621 is greater than the height of the second outer wall 1622, which will effectively prevent the risk of leakage at the connection between the lower inner liner 152 and the partition 16.

[0123] Further details are available according to... Figure 13 As shown, the second extension 121 abuts against the second inner sidewall 1621, while the second bent portion 122 abuts against the second outer sidewall 1622. This results in a larger contact area between the second extension 121 and the second inner sidewall 1621, which not only better ensures that there is no risk of leakage at the connection between the lower inner liner 152 and the partition 16, but also allows for more even stress distribution between the lower inner liner 152 and the partition 16, reducing the risk of structural damage or deformation due to localized stress concentration, thereby improving the stability and reliability of the entire structure.

[0124] It should be further noted that the height difference between the first inner wall 1611 and the first outer wall 1612 is the first height difference ΔHx1, which is ≥3mm. The height difference between the second inner wall 1621 and the second outer wall 1622 is the second height difference ΔHx2, which is ≥0.

[0125] Specifically, the height of the first inner sidewall 1611 is defined as the first inner height Hn1, where Hn1 ≥ 5mm. This effectively ensures reliable assembly between the first slot 13 and the first insertion part 11, preventing misalignment and deformation of the upper washing chamber 1531. The height of the second inner sidewall 1621 is defined as the second inner height Hn2, where Hn2 ≥ 5mm. This not only effectively ensures reliable assembly between the second slot 14 and the second insertion part 12, preventing misalignment and deformation of the lower washing chamber 1532, but also provides a certain degree of effective water leakage prevention.

[0126] Preferably, please refer to the following for details. Figures 3 to 5 As shown, a guide slope 1633 is provided on the side of the first inner sidewall 1611 near the upper washing chamber 1531, and the guide slope 1633 is inclined to the first inner sidewall 1611. Specifically, the guide slope 1633 is inclined downward along the direction near the center of the upper inner liner 151. The guide slope 1633 is preferably a plane, that is, the guide slope 1633 has a chamfered structure. Of course, the guide slope 1633 can also be selected as a raised arc-shaped surface, that is, the guide slope 1633 has a rounded corner structure. Alternatively, the guide slope 1633 can also be selected as a concave arc-shaped surface.

[0127] Thus, under the action of the guide slope 1633, the water flows in the direction of its inclination, preventing the water from splashing randomly or flowing vertically downwards, and helping to concentrate the water flow to a specific location. Simultaneously, during the operation of the dishwasher 1, a large amount of water vapor is generated inside. The inclined guide slope 1633 allows the condensed water vapor to be concentrated and guided to a specific location on the separator 16 more quickly, preventing the water vapor from condensing randomly on the first inner wall 1611 and forming water droplets. It also accelerates the drainage speed. This not only reduces the internal dampness of the dishwasher 1 caused by water vapor condensation, but also shortens the duration of the damp environment inside the upper washing chamber 1531 and maintains a dry environment inside the upper washing chamber 1531, reducing problems such as component corrosion and mold caused by dampness, and also reducing the time of water accumulation in the washing chamber. This improves the overall working efficiency of the dishwasher 1, especially in the drainage stage, where drainage can be completed more quickly, saving time for subsequent rinsing and drying processes, and improving the reliability and stability of the dishwasher 11.

[0128] When the guide slope 1633 is a plane, the angle formed between the guide slope 1633 and the horizontal plane is β, where β ≥ 5°. After assembly, the lower bottom surface of the partition 16 is parallel to this horizontal plane. Thus, when β ≥ 5°, the larger β ensures that the water flow can smoothly follow the guide slope 1633 under the influence of gravity, being guided to the expected direction and position, improving the efficiency and accuracy of water flow guidance, and preventing irregular flow or accumulation of water near the first inner wall 1611. Simultaneously, a larger β allows the water flow to gain a certain acceleration, increasing its speed and kinetic energy. This not only enhances the scouring effect on the guide slope 1633 and the first inner wall 1611, but also more effectively removes dirt and impurities adhering to them, helping to maintain the cleanliness of the upper washing chamber 1531. It also reduces water stagnation in the upper washing chamber 1531, accelerating drainage and thus improving the efficiency of the entire dishwasher 1's workflow, saving time for subsequent washing and rinsing processes. In addition, it can also make water vapor condense quickly and flow down the guide slope 1633 rapidly, reducing the accumulation time and amount of water vapor on the guide slope 1633 and the first inner sidewall 1611, which is conducive to keeping the inside of the dishwasher 1 dry and reducing the probability of problems such as bacterial growth and component corrosion caused by water vapor accumulation.

[0129] Conversely, when β < 5°, the angle is too small, which is not conducive to water vapor condensation. This causes water vapor to easily accumulate on the guide slope 1633 and the first inner sidewall 1611, forming water droplets. This increases the humidity inside the upper washing chamber 1531 and prolongs the drying time. At the same time, the water flow may not be able to flow quickly and smoothly along the guide slope 1633 as designed, and may even stagnate or backflow on the guide slope 1633. This will not only reduce the working efficiency of the dishwasher 1, but may also have adverse effects on some components of the dishwasher 1 due to prolonged water accumulation.

[0130] Furthermore, please refer to the specific details. Figures 3 to 5 As shown, the first inner sidewall 1611 has a reinforcing wall 1631 protruding upward along its height direction. Preferably, multiple reinforcing walls 1631 are arranged, spaced apart along the length of the first inner sidewall 1611, and a guide groove 1632 is formed between the first inner sidewall 1611 and two adjacent reinforcing walls 1631. Thus, when the first extension 111 abuts against and fits against the first inner sidewall 1611, the first extension 111 of the first insertion part 11 will also abut against and fit against the reinforcing wall 1631, thereby increasing the force-bearing area between the first insertion part 11 and the first slot 13 and improving assembly stability.

[0131] It should be noted that, please refer to Figure 15The distance between two adjacent reinforcing walls 1631 is the distribution spacing L. It can be understood that the distance formed by the centerlines of the two reinforcing walls 1631 is the distribution spacing L, and the distribution spacing L ≥ 10mm. Based on the insertion principle between the first insertion part 11 and the first slot 13, a distribution spacing L ≥ 10mm effectively provides assembly limits and increases assembly reliability. However, when the distribution spacing L < 10mm, the distance between two adjacent reinforcing walls 1631 is smaller. During mold processing, the requirements for machining accuracy will significantly increase, making toolpath planning and cutting parameter selection more difficult. This necessitates the use of more precise machining equipment and more advanced machining processes, and also places higher demands on the strength, hardness, and wear resistance of the mold material. This leads to mold complexity and increases the production cost of the separator 16.

[0132] In addition to the aforementioned arrangement where the upper inner liner 151 and the lower inner liner 152 are respectively provided with a first insertion part 11 and a second insertion part 12, and the partition 16 is provided with a first slot 13 for inserting the first insertion part 11 and a second slot 14 for inserting the second insertion part 12, the inventors have also provided another preferred embodiment, which can be referred to in conjunction with the above-mentioned embodiments. Figure 5 and Figure 6 As shown, the upper and lower sides of the partition 16 are respectively provided with a first insertion part 11 and a second insertion part 12, and both the first insertion part 11 and the second insertion part 12 are preferably located near the edge of the partition 16. The upper inner liner 151 is provided with a downward-opening first slot 13, and the first insertion part 11 is inserted into the first slot 13. The lower inner liner 152 is provided with an upward-opening second slot 14, and the second insertion part 12 is inserted into the second slot 14. During assembly, the upper inner liner 151 and the lower inner liner 152 are respectively located on the upper and lower sides of the partition 16, and the upper inner liner 151 and the partition 16 form an upper washing chamber 1531, and the lower inner liner 152 and the partition 16 form a lower washing chamber 1532. The upper washing chamber 1531 and the lower washing chamber 1532 are relatively independent.

[0133] This setup will have the following unexpected technical effects:

[0134] 1. The upper inner liner 151 and lower inner liner 152 are respectively inserted and assembled with the partition 16, simplifying the assembly process and reducing the difficulty of assembly and the skill requirements for workers. Compared with complex welding, riveting and other connection methods, it can also improve assembly speed and reduce assembly time and labor costs. During the assembly process or during later maintenance and replacement, the upper inner liner 151 or lower inner liner 152 can be more easily separated from the partition 16, reducing the difficulty of disassembly and maintenance, thereby reducing assembly and maintenance costs.

[0135] 2. The plug-in assembly method helps improve assembly accuracy. The first slot 13 and the second slot 14 can serve as positioning structures, guiding the upper inner tank 151 and the lower inner tank 152 to be accurately installed on both sides of the separator 16, ensuring the positional accuracy and structural stability of the upper washing chamber 1531 and the lower washing chamber 1532. This precise assembly method can reduce quality problems caused by improper assembly, such as poor sealing of the washing chamber and deviation of the spray angle of the spray device 102, thereby improving the quality stability of the product.

[0136] As a preferred embodiment, please refer to the following for details. Figure 16 and Figure 17 As shown, the upper inner liner 151 also includes an upper limit member 1512. The upper body 1511 is bent into an upper bent top wall 15114 on the side facing the upper washing chamber 1531, and the end of the upper bent top wall 15114 is bent into an upper bent side wall 15115 on the side facing the partition 16. That is, the upper inner liner side wall 15113 and / or the upper inner liner back wall 15112 are bent into an upper bent top wall 15114 and an upper bent side wall 15115 near the partition 16. The upper bent side wall 15115 preferably extends perpendicular to the partition 16. The upper limit member 1512 connects to the upper body 1511 to cooperate with the upper bent top wall 15114 and the upper bent side wall 15115 to form the first slot 13. The "fitting" here should be understood as attaching the upper limit part 1512 to the upper body 1511 and then installing and fixing it using at least one of the following processes: snap-fit ​​connection, welding connection, riveting connection, or adhesive connection.

[0137] Therefore, compared to the integrally formed upper inner liner 151 structure, disassembling the upper inner liner 151 into the upper main body 1511 and the upper limit component 1512, manufacturing them separately, and then assembling them can reduce the manufacturing difficulty of the upper inner liner 151, improve production efficiency, and reduce production costs.

[0138] Furthermore, please refer to the specific details. Figure 16 and Figure 17As shown, the upper bent top wall 15114 is inclined to the upper limit stop 1512 and extends towards the separator 16, so that the upper bent top wall 15114 and the upper limit stop 1512 are set at an angle. The end of the first insertion part 11 away from the separator 16 is provided with an upper positioning part 113, which abuts against the upper bent top wall 15114. That is, the upper positioning part 113 has an upper positioning surface and a side positioning surface, which intersect at an angle, and the angle formed by the intersection of the upper positioning surface and the side positioning surface is adapted to the angle formed by the upper bent top wall 15114 and the upper limit stop 1512. It can be understood that the angle formed by the upper positioning part 113 and the horizontal plane is δ, specifically the angle formed by the upper positioning surface and the horizontal plane is δ, and the angle formed by the upper bent top wall 15114 and the horizontal plane is γ, and the angle of γ is equal to the angle of δ. The equality here should also include δ and γ being within the assembly tolerance range.

[0139] This allows the first insertion part 11 to fit more precisely with the upper inner tank 151 during assembly, ensuring accurate relative positioning between the upper inner tank 151 and the separator 16. This guarantees the dimensional and shape accuracy of the upper washing chamber 1531, improving the overall assembly quality of the dishwasher 1's internal structure. Simultaneously, it effectively reduces the difficulty of positioning, increases positioning efficiency, and facilitates waste removal during subsequent cleaning. Furthermore, it offers the following unexpected technical benefits:

[0140] On the one hand, the tight fit between the upper positioning part 113 and the upper bent top wall 15114 increases the contact area and friction between the upper inner liner 151 and the partition 16, making the connection between the two more stable. During the operation of the dishwasher 1, it can effectively resist external forces generated by water flow impact, vibration, etc., improve the connection strength, reduce the relative displacement and loosening between the two, and extend the service life of the dishwasher 1. Furthermore, during the stress process, it can evenly distribute the external force to each component, avoiding stress concentration. This helps to improve the strength and reliability of the entire structure and reduce the risk of component damage due to excessive local stress.

[0141] On the other hand, precise assembly and tight fit, combined with the angled arrangement of the upper bent top wall 15114 and the upper limit part 1512, can effectively improve the sealing of the upper washing chamber 1531, prevent water from leaking to the outside of the upper inner tub 151 during the washing process, ensure the normal operation of the dishwasher 1, and also avoid electrical failures and other problems that may be caused by water leakage, thereby improving the safety and stability of the product.

[0142] For further details, please refer to [link / reference]. Figure 17Along the first groove depth direction T1 of the first slot 13, the distance formed between the end of the upper bent sidewall 15115 near the separator 16 and the end of the upper bent top wall 15114 away from the separator 16 is the upper assembly height h1. Along the direction perpendicular to the separator 16, the height of the protrusion of the first insertion part 11 is the first height H1, and the upper assembly height h1 is greater than the first height H1.

[0143] Thus, the larger upper assembly height h1 creates a relatively tortuous path at the insertion point of the first insertion part 11 and the first slot 13. This tortuous path increases the resistance to water flow, making it more difficult for water in the washing chamber to leak out through this gap. Even if a small amount of water seeps into the joint, it needs to travel a longer path to reach the outside, greatly reducing the possibility of leakage. Simultaneously, it effectively hinders the movement of water between different washing chambers, improving the structure's sealing and stability. Furthermore, the larger upper assembly height h1 provides more ample operating space for the first insertion part 11 to insert into the first slot 13. Assemblers can more easily align the first insertion part 11 with the first slot 13, and even if there are some deviations during assembly, there is sufficient space for fine-tuning, ensuring that the first insertion part 11 can be accurately inserted into the correct position, reducing assembly difficulty and improving positioning and assembly efficiency.

[0144] Preferably, the first height H1 is ≥ 3mm. This not only ensures sufficient contact area between the first insertion part 11 and the first slot 13, but also, during assembly, a larger contact area means increased friction, which helps the first insertion part 11 to be inserted more securely into the first slot 13, making it less prone to loosening. This makes the connection between the upper inner liner 151 and the separator 16 tighter and more reliable, ensuring the stability and assembly reliability of the entire dishwasher 1 structure. This ensures that the dishwasher 1 can better resist the effects of vibration, water flow impact, and other factors during operation, reducing or even avoiding the risk of displacement or detachment of components due to loose connections. It also provides clearer guidance and positioning for assembly, more effectively correcting any minor deviations and ensuring the accurate relative position of the upper inner liner 151 and the separator 16, thereby improving the precision and quality of assembly.

[0145] Meanwhile, when the first height H1 ≥ 3mm, a sufficiently long path is formed at the mating point of the first insertion part 11 and the first slot 13. For water to leak out of the upper washing chamber 1531, it needs to overcome a longer distance and greater resistance, increasing the difficulty of water leakage. This effectively prevents water from splashing out or leaking to the outside of the dishwasher 1, ensuring the waterproof performance of the dishwasher 1, protecting the electrical components inside the dishwasher 1, and extending the service life of the dishwasher 1.

[0146] Furthermore, the first height H1 ≥ 3mm provides sufficient operating space for sheet metal bending. During the bending process, a larger height makes it easier to bend the sheet metal into the required shape, which is more conducive to the sheet metal forming of the upper inner liner 151. It reduces the risk of material cracking or deformation caused by too small a bending radius, helps to ensure the accuracy and quality of bending, and makes the shape and size of the first insertion part 11 more in line with the design requirements, thereby improving the product qualification rate and production efficiency.

[0147] When the first height H1 < 3, the contact area between the first insertion part 11 and the first slot 13 is insufficient, making the connection between them unstable. This makes them prone to loosening during dishwasher 1 operation due to vibration or external force, significantly reducing assembly reliability. Simultaneously, it weakens the guiding and positioning functions during assembly, making deviations and misalignments more likely. Furthermore, the waterproofing performance decreases, making it easier for water to leak from the mating point between the first insertion part 11 and the first slot 13, greatly increasing the possibility of water leakage from the dishwasher 1.

[0148] As a preferred embodiment, please refer to the following for details. Figure 16 and Figure 17 As shown, the lower inner liner 152 also includes a lower limiting member 1522. The lower main body 1521 is bent to form a lower bent bottom wall 15215 on the side facing the lower washing chamber 1532, and the end of the lower bent bottom wall 15215 is bent to form a lower bent side wall 15216 on the side facing the partition 16. That is, the lower inner liner side wall 15213 and / or the lower inner liner back wall 15212 are bent to form a lower bent bottom wall 15215 and a lower bent side wall 15216 at the end near the partition 16. The upper bent side wall 15115 preferably extends perpendicular to the partition 16, and the lower limiting member 1522 connects to the lower main body 1521 to cooperate with the lower bent bottom wall 15215 and the lower bent side wall 15216 to form a second slot 14. The "fitting" here should be understood as installing and fixing the lower limit piece 1522 to the lower body 1521 using at least one of the following processes: snap-fit ​​connection, welding connection, riveting connection, or adhesive connection.

[0149] Therefore, compared to the integrally formed lower inner liner 152 structure, disassembling the lower inner liner 152 into the lower main body 1521 and the lower limiting component 1522, manufacturing them separately, and then assembling them can reduce the manufacturing difficulty of the lower inner liner 152, improve production efficiency, and reduce production costs.

[0150] It should be noted that the lower bent bottom wall 15215 is inclined to the lower limiting member 1522 and extends towards the separator 16, so that the lower bent bottom wall 15215 and the lower limiting member 1522 are set at an angle. The end of the second insertion part 12 away from the separator 16 is provided with a lower positioning part, which abuts against the lower bent bottom wall 15215. That is, the upper positioning part 113 has a lower positioning surface and a side limiting surface, the lower positioning surface and the side limiting surface are set at an angle, and the angle formed by the intersection of the lower positioning surface and the side limiting surface is adapted to the angle formed by the lower bent bottom wall 15215 and the lower limiting member 1522. The adaptation here should be understood as the two angles being equal and the two angles being within the assembly tolerance range.

[0151] This allows the second insertion part 12 to fit more precisely with the lower inner tank 152 during assembly, ensuring accurate relative positioning between the lower inner tank 152 and the partition 16. This guarantees the dimensional and shape accuracy of the lower washing chamber 1532, improving the overall assembly quality of the dishwasher 1's internal structure. Simultaneously, it effectively reduces positioning difficulty and increases positioning efficiency. Furthermore, the tight fit between the lower positioning part and the lower bent bottom wall 15215 increases the contact area and friction between the lower inner tank 152 and the partition 16, making the connection more stable and increasing its strength. This contributes to improving the overall structural strength and reliability, reducing the risk of component damage due to excessive localized stress.

[0152] Of course, please refer to the specifics. Figure 16 and Figure 17 As shown, the lower bent bottom wall 15215 can also be set perpendicular to the lower limit member 1522, which can also ensure the assembly accuracy and structural stability between the lower inner liner 152 and the partition member 16. At the same time, the processing and forming are simpler, reducing the processing difficulty and thus helping to reduce the production cost.

[0153] For further details, please refer to [link / reference]. Figure 17 Along the second groove depth direction T2 of the second slot 14, the distance formed between the end of the lower bent sidewall 15216 near the separator 16 and the end of the lower bent bottom wall 15215 away from the separator 16 is the lower assembly height h2. Along the direction perpendicular to the separator 16, the height of the protrusion of the second insertion part 12 is the second height H2, and the lower assembly height h2 is greater than or equal to the second height H2.

[0154] In this way, a relatively tortuous and relatively long path is formed at the insertion point of the second connector 12 and the second slot 14. During the operation of the dishwasher 1, if water in the lower washing chamber 1532 is to leak, it needs to flow along this longer path. The water is affected by friction and other resistance during its flow; the longer the path, the greater the resistance, and the more difficult it is for water to leak. This significantly reduces the possibility of water leaking from the gap between the second slot 14 and the second connector 12 to the outside of the dishwasher 1, effectively preventing water leakage.

[0155] Preferably, the second height H2 ≥ 3mm. This not only ensures a sufficiently long path between the second insertion part 12 and the second slot 14, but also prevents water from leaking out of the lower washing chamber 1532. This increases the difficulty of water leakage, effectively preventing water from splashing out or leaking to the outside of the dishwasher 1, ensuring the waterproof performance of the dishwasher 1, protecting the internal electrical components, and extending the service life of the dishwasher 1. Simultaneously, it provides sufficient operating space for sheet metal bending. During bending, a larger height makes it easier to bend the sheet metal into the required shape, which is more conducive to the sheet metal forming of the lower inner liner 152. This reduces the risk of material cracking or deformation due to an excessively small bending radius, helps ensure bending accuracy and quality, and makes the shape and size of the second insertion part 12 more in line with design requirements, improving product qualification rate and production efficiency.

[0156] However, since the second height H2 is less than 3mm, the insufficient contact area between the second insertion part 12 and the second slot 14 makes the connection between them unstable. This makes it easy for the dishwasher 1 to loosen during operation due to vibration or external force, significantly reducing the assembly reliability of the dishwasher 1. Simultaneously, it also reduces waterproofing performance, allowing water to easily leak from the mating point between the second insertion part 12 and the second slot 14, greatly increasing the possibility of water leakage from the dishwasher 1.

[0157] Preferably, please refer to 16 and Figure 17 As shown, the first slot width dimension B1 of the first slot 13 is greater than or equal to the first thickness dimension K1 of the first insertion part 11 in the first slot width direction Tu of the first slot 13, and the second slot width dimension B2 of the second slot 14 is greater than or equal to the second thickness dimension K2 of the second insertion part 12 in the second slot width direction Tl of the second slot 14.

[0158] This design, with its slightly wider slots, provides ample room for the insert parts to move within the slots, allowing for fine-tuning during assembly to ensure accurate relative positioning between the upper inner liner 151, the lower inner liner 152, and the separator 16. It also facilitates the insertion of the first insert part 11 and the second insert part 12 into their corresponding slots during assembly, reducing insertion difficulties caused by dimensional tolerances or minor deviations during assembly, lowering the precision requirements for assembly workers, and improving assembly efficiency. Furthermore, it appropriately reduces the requirements for manufacturing precision, decreases the scrap rate during manufacturing, increases production efficiency, and lowers production costs.

[0159] It should be noted that the first thickness dimension K1 ≥ 2mm and the second thickness dimension K2 ≥ 2mm. This can effectively ensure that the first plug part 11 and the second plug part 12 have sufficient strength to withstand various external forces during assembly and use, avoid deformation or damage due to excessive thickness, and also ensure that the dishwasher 1 can resist external forces such as water flow impact and vibration when it is working, thus ensuring the stability and reliability of the dishwasher 1.

[0160] When both the first thickness dimension K1 and the second thickness dimension K2 are less than 2 mm, the structural strength will be significantly reduced due to the insufficient thickness of the first insertion part 11 and the second insertion part 12. During assembly, a certain amount of external force is required when inserting into the slot, and the thinner insertion part may bend, break, or deform, making it impossible to complete the assembly normally. During the use of the dishwasher 1, the insufficiently thick insertion part is more prone to deformation or even damage due to factors such as water flow impact, vibration, and internal pressure changes, thereby disrupting the connection structure between the upper inner tank 151, the lower inner tank 152, and the separator 16, greatly reducing the overall stability and sealing of the dishwasher 1 and affecting its normal use. At the same time, because the thinner first insertion part 11 and the second insertion part 12 have limited deformation capacity under external force, they are more prone to cracking and wrinkling during bending, stamping, and other forming processes, thereby increasing the difficulty of forming and the scrap rate.

[0161] Furthermore, please refer to 16 and... Figure 17As shown, the separator 16 is provided with a recessed groove 165. The groove opening of the recessed groove 165 is downwardly positioned on the side facing the lower washing chamber 1532, and the recessed groove 165 is located on the side of the second insertion part 12 opposite to the lower limiting member 1522. The lower bent side wall 15216 can extend into the recessed groove 165. In this way, the recessed groove 165 and the lower bent side wall 15216 will also form a tortuous path for the insertion and engagement. When water attempts to leak from the lower washing chamber 1532, it needs to travel a longer distance and encounter more obstacles, further increasing the difficulty of leakage. This effectively prevents the washing liquid from leaking from the connection part 1683 between the lower inner tank 152 and the separator 16 to other parts of the dishwasher 1, thus improving the waterproof performance of the dishwasher 1.

[0162] In addition to the above-mentioned method where both the upper inner liner 151 and the lower inner liner 152 are connected to the partition 16 by insertion, the inventor also provides another preferred embodiment, which can be referred to in conjunction with the above-mentioned method. Figure 7 and Figure 8 As shown, the upper inner liner sidewall 15113 and the lower inner liner sidewall 15213 are integrally formed as inner liner sidewalls. The inner liner sidewalls are separately formed workpieces, meaning the upper left sidewall and lower left sidewall are integrally formed, and the upper right sidewall and lower right sidewall are integrally formed. The upper inner liner backwall 15112 and the lower inner liner backwall 15212 are integrally formed as inner liner backwalls, which are separately formed workpieces. Further, the aforementioned separator 16 includes a folding portion 167, which is sealed to the inner wall of the washing cavity 153. That is, both the inner liner sidewall and the inner liner backwall are sealed to the folding portion 167. After assembly, the separator 16 is assembled into the washing cavity 153 to divide the washing cavity 153 into an upper washing cavity 1531 and a lower washing cavity 1532, which are relatively independent.

[0163] This setup will have the following unexpected technical effects:

[0164] 1. Compared with the separately molded upper and lower inner tank 152 components, the one-piece molding design can further reduce connection points and gaps, reduce the probability of structural weak points, and thus better withstand the internal pressure, water flow impact and external collision forces when the dishwasher 1 is working. In addition, it can better maintain its shape during operation, reduce deformation caused by vibration or other external forces, and improve the overall strength, durability and structural stability of the inner tank 15.

[0165] 2. In terms of assembly, it can further simplify assembly steps, reduce assembly difficulty, improve assembly accuracy and efficiency, and reduce quality problems caused by inaccurate component alignment during assembly. It can also ensure that the separator 16 accurately divides the washing chamber 153 into relatively independent upper washing chamber 1531 and lower washing chamber 1532, avoiding problems such as poor connection or sealing between the two washing chambers due to assembly errors.

[0166] 3. The one-piece molded inner drum 15 reduces internal gaps and corners, making the interior of the dishwasher 1 easier to clean. After daily use, users can more easily clean dirt and residue from the upper washing chamber 1531 and lower washing chamber 1532, reducing cleaning difficulty and time costs. Furthermore, when maintenance is needed, the reduced number of parts makes it easier for maintenance personnel to locate and resolve problems, improving maintenance efficiency.

[0167] It should be noted that the aforementioned sealing connection should be understood as a welded and / or adhesive connection between the folded portion 167 and the inner wall of the washing cavity 153. For example, the assembler first precisely places the separator 16 in a suitable position within the washing cavity 153, ensuring the folded portion 167 fits tightly against the inner wall. Then, using laser welding equipment, a welding connection is made along the contact edge between the folded portion 167 and the inner wall, generating high temperatures to fuse the folded portion 167 and the inner wall together. This welding process is fast and precise, producing a uniform and aesthetically pleasing weld with high strength, capable of withstanding the internal pressure and water flow impact during dishwasher operation.

[0168] For example, the assembler first cleans the surface of the folding part 167 and the surface of the inner wall of the cavity to remove oil, dust, and other impurities to ensure better adhesion of the sealant. Then, using a caulking gun, the sealant is evenly applied to the contact surface between the folding part 167 and the inner wall of the cavity. After application, the separator 16 is quickly installed into the washing cavity 153, ensuring a tight fit between the folding part 167 and the inner wall, and excess sealant is squeezed out. During the curing process of the sealant, an elastic sealing layer is formed, filling the tiny gaps between the folding part 167 and the inner wall of the cavity. This allows it to accommodate minor deformations caused by temperature changes and vibrations during operation of the dishwasher 1, maintaining good sealing performance. Moreover, this adhesive bonding method is relatively simple to operate, low in cost, and easy to maintain when needed. If the separator 16 needs to be replaced or repaired later, only the cured sealant needs to be removed, without damaging the inner tank 15.

[0169] Preferably, please refer to the following for details. Figure 7 , Figure 8 and Figure 11As shown, the aforementioned partition 16 includes a water guide slope 1681, which is located on the side of the folded portion 167 facing away from the inner wall of the cavity. The water guide slope 1681 extends downward at an angle in the direction away from the inner wall of the cavity and towards the lower washing cavity 1532.

[0170] Under the action of the water guide slope 1681, during the operation of the dishwasher 1, the impurities such as food residue, oil stains, and dirty water generated in the upper washing chamber 1531 can flow smoothly and quickly towards the inside of the separator 16, which facilitates centralized discharge, shortens drainage time, improves the overall working efficiency of the dishwasher 1, reduces the erosion of impurities on the inner tank 15 and other components (such as the spray device 102), extends the service life of the dishwasher 1, and also prevents impurities from accumulating in the upper washing chamber 1531, thereby reducing secondary pollution of tableware by sewage and improving the washing effect.

[0171] As a preferred embodiment, please refer to the following for details. Figure 18 and Figure 19 As shown, the separator 16 also includes a connecting portion 1683, which connects the water guide slope 1681 and the folding portion 167. Preferably, the connecting portion 1683, the water guide slope 1681, and the folding portion 167 are integrally formed. The connecting portion 1683 is preferably perpendicular to the inner wall of the washing cavity 153, that is, the connecting portion 1683 is parallel to the horizontal plane, and the folding portion 167 extends perpendicular to the connecting portion 1683 to ensure that the folding portion 167 better abuts against and fits against the inner wall of the cavity. Further, the inner tank 15 has a protruding limiting rib 154 protruding towards the interior of the washing cavity 153. The inner tank sidewall and the inner tank backwall preferably both have limiting ribs 154, and the connecting portion 1683 abuts against the limiting rib 154. The cross-sectional shape of the limiting rib 154 can be rectangular, trapezoidal, semi-circular, etc., and the cross-sectional shape and size of the limiting rib 154 are not limited here.

[0172] This setup will achieve the following technical effects:

[0173] Firstly, the limiting rib 154 is equivalent to adding reinforcing ribs to the surface of the inner tank 15, which can improve the rigidity of the inner tank 15. The increased rigidity makes the inner tank 15 less prone to bending or deformation when subjected to external forces, maintaining its original shape and dimensional accuracy. At the same time, the limiting rib 154 also acts as a damping agent, absorbing and dissipating the vibration energy generated by the dishwasher 1 during operation, which helps to improve the vibration resistance of the inner tank 15, extend the service life of the inner tank 15, and reduce noise caused by vibration.

[0174] Secondly, during assembly, workers only need to align the connecting part 1683 with the limiting rib 154 and make the connecting part 1683 of the partition 16 abut against the bottom of the limiting rib 154 to achieve the installation and positioning of the partition 16, which greatly improves the positioning efficiency and assembly efficiency, and reduces assembly time and labor costs. At the same time, it can also improve the assembly accuracy of the partition 16, thereby ensuring the relative positional accuracy and dimensional accuracy of the upper washing chamber 1531 and the lower washing chamber 1532.

[0175] Thirdly, when using adhesive bonding, the sealant can adhere to and fill the space between the limiting rib 154 and the connecting part 1683, thereby increasing the contact area between the connecting part 1683 and the inner wall of the washing cavity 153, thus improving the strength and stability of the adhesive bond. Simultaneously, the limiting rib 154 provides support and fixation for the connecting part 1683, preventing displacement during adhesive curing and ensuring the quality of the adhesive bond. Furthermore, the tight fit between the limiting rib 154 and the connecting part 1683 ensures their relative positions remain constant during welding, resulting in more precise and uniform weld points, improving weld quality and strength. During welding, the limiting rib 154 also provides some heat dissipation, helping to control the temperature of the welding area and reducing welding deformation and cracking. In addition, the stable fit makes the welding process smoother, improves welding efficiency, and reduces welding costs. Whether it is an adhesive connection or a welded connection, the cooperation between the limiting rib 154 and the connecting part 1683 helps to improve the sealing between the partition 16 and the inner wall of the cavity, effectively preventing water leakage.

[0176] It should be noted that, for details please refer to [link / reference]. Figure 18The angle formed between the guide slope 1681 and the connecting part 1683 is α, which is not less than 5° and not greater than 75°. This allows the guide slope 1681 to provide a suitable angle for the wastewater in the upper washing chamber 1531. Impurities can flow steadily downwards under gravity, ensuring that wastewater containing residue is smoothly discharged, reducing the residence time of impurities in the upper washing chamber 1531, improving drainage efficiency, and reducing the possibility of secondary contamination of tableware. However, when α < 5°, the guide slope 1681 is too gentle. When impurities flow on the guide slope 1681, the component of gravity along the direction of the guide slope 1681 is small, resulting in insufficient driving force for the water flow and a significantly slower discharge speed. This causes impurities to remain in the upper washing chamber 1531 for too long, and may even lead to the accumulation of residue on the guide slope 1681, posing a risk of blockage, increasing the risk of secondary contamination of tableware, and reducing the washing effect of the dishwasher 1. When α > 75°, an excessively steep α makes the guide slope 1681 too steep. Under gravity, wastewater will flow down at a high speed, easily causing splashing. This splashed wastewater may then contaminate other parts of the upper washing chamber 1531, thus polluting the inside of the dishwasher 1. Simultaneously, the high-speed water flow colliding with the guide slope 1681 and the inner walls of the lower washing chamber 1532 will generate significant noise. This not only affects the user experience when using the dishwasher 1 but may also indicate unstable water flow, negatively impacting the overall performance of the dishwasher 1.

[0177] It should also be noted that, for details please refer to [link / reference]. Figure 18 The distance between one side of the connecting part 1683 that connects to the water guide slope 1681 and one side that connects to the folded part 167 is the platform width Bp, which is not less than 3mm and not more than 15mm. If the platform width Bp < 3mm, the connecting part 1683 becomes too narrow, leaving very little space for forming a weld, making it impossible to form a weld of sufficient size and strength. A weld that is too narrow or shallow will result in insufficient bonding between the connecting part 1683 and other components, and will severely limit the space for welding operations. Welding tools will be difficult to accurately position at the welding points, and welding guns or electrodes may not be able to stably align with the connection between the connecting part 1683 and the water guide slope 1681 and folded part 167, easily leading to welding position deviations and substandard welding quality. Furthermore, it significantly increases the difficulty of forming the connecting part 1683.

[0178] If the platform width Bp > 15mm, making the connecting part 1683 too wide, the water flow area will be too large when flowing from the connecting part 1683 to the guide slope 1681, the flow velocity will be dispersed, and the kinetic energy of the water flow will be weakened. At the same time, it will also lengthen the flow path of the water on the connecting part 1683, increase the travel time of the water flow, reduce the timeliness of drainage, and make it difficult for the sewage carrying residue to flow quickly up the guide slope 1681. This may cause some sewage and residue to remain on the connecting part 1683, affecting the drainage effect.

[0179] The platform width Bp is not less than 3mm and not more than 15mm. This not only helps ensure the structural strength and stability of the connecting part 1683, better withstands external forces such as water flow impact and vibration during the operation of the dishwasher 1, and reduces the risk of loosening, breakage, and deformation, but also facilitates the welding connection between the connecting part 1683 and other components. Simultaneously, it ensures smooth water flow, prevents the risk of water congestion when flowing from the connecting part 1683 to the guide slope 1681, improves drainage efficiency, and thus helps keep the platform surface dry, reducing the possibility of bacterial growth and maintaining the cleanliness and hygiene of the inside of the dishwasher 1.

[0180] In addition, please see details. Figure 18 The protrusion height Hb of the aforementioned limiting rib 154 is not less than 1mm and not more than 15mm. This not only provides a clear limiting effect for the separator 16, but also ensures the strength of the limiting rib 154 itself, enabling it to maintain its structural integrity when subjected to external forces and preventing breakage or deformation. If the protrusion height Hb > 15mm, the limiting rib 154 becomes too high, which can easily lead to stress concentration, reducing the overall strength of the main structure. Furthermore, it will occupy more vertical space in the upper washing chamber 1531, interfering with or hindering the placement of tableware into the upper washing chamber 1531, affecting the washing experience and washing effect. If the protrusion height Hb < 1mm, the limiting rib 154 is too small, which is not conducive to the forming process of the limiting rib 154.

[0181] Understandably, please refer to the specific details. Figure 11 As shown, the partition 16 also includes a partition support portion 1682, which is connected to the water guide slope 1681. The connection here is preferably integrally formed to better prevent leakage at the connection between the partition support portion 1682 and the water guide slope 1681 and to enhance the overall stability of the partition 16. The partition support portion 1682 and the water guide slope 1681 form the drainage channel 164 described above.

[0182] It should be noted that, for details please refer to... Figure 18As shown, the depth Hd of the drainage trough 164 is not less than 3mm and not more than 20mm. This ensures that the drainage trough 164 has sufficient space to accommodate the water flow, allowing the water to form a certain depth within the trough and flow stably and orderly within a relatively stable space. This avoids water overflowing the drainage trough 164 due to an insufficient depth Hd (Hd < 3mm) and water flow turbulence caused by external factors (such as air resistance), which would affect the smoothness of drainage. Simultaneously, it also helps the water flow smoothly under gravity, carrying away smaller debris and dirt, reducing the risk of clogging the drainage trough 164. If the depth Hd is too shallow (Hd < 3mm), the flushing force of the water flow is insufficient, and debris and dirt easily accumulate at the bottom of the drainage trough 164, leading to poor drainage or even clogging. Therefore, this effectively reduces the residence time of water within the drainage trough 164, improving drainage efficiency.

[0183] Furthermore, the depth Hd of the drainage channel 164 is not less than 3mm and not more than 20mm, which facilitates processing and ensures that the overall structure of the drainage channel 164 has sufficient structural strength and stability. This is because the depth Hd of the drainage channel 164 affects its overall structural strength. If the depth Hd is too large (Hd > 20mm), it will not only be difficult to form, but will also make the structure of other components (such as the water cup 17) too weak at the drainage channel 164, making them prone to deformation and cracking when subjected to external forces or water pressure.

[0184] In addition to the aforementioned method of providing a folding portion 167 to the partition 16 and sealing it to the cavity wall of the washing inner cavity 153 using the folding portion 167, the inventors have also provided another preferred embodiment, which can be found in conjunction with... Figures 20 to 24 As shown, the aforementioned partition 16 includes a partition plate 160 and a mounting bracket 169. Specifically, both the inner tank sidewall and the inner tank backwall are sealed to the mounting bracket 169, and the mounting bracket 169 is detachably connected to the partition plate 160. After assembly, the partition plate 160 is mounted on the inner wall of the washing cavity 153 via the mounting bracket 169, thereby dividing the washing cavity 153 into an upper washing cavity 1531 and a lower washing cavity 1532 arranged sequentially from top to bottom. The upper washing cavity 1531 and the lower washing cavity 1532 are relatively independent.

[0185] With this configuration, the partition plate 160 and the mounting bracket 169 can be produced as independent parts in the factory in a standardized manner, making it easier to control precision. During installation, only the partition plate 160 and the mounting bracket 169 need to be assembled, and then the mounting bracket 169 can be precisely installed onto the inner wall of the washing cavity 153. This not only ensures the accuracy and stability of the washing cavity partition and improves the washing effect, but also the partition plate 160 has a simple structure and is easy to assemble, solving the problem of the relatively complex and difficult installation process of the existing dishwasher 1. This effectively improves the flexibility and applicability of the dishwasher 1 and helps to reduce the production cost of the dishwasher 1.

[0186] Furthermore, to ensure the airtightness between the separator 16 and the inner liner 15, please refer to the following for details. Figures 20 to 24 As shown, the edge of the mounting bracket 169 and the inner wall of the washing cavity 153 form a separating sealing groove 181, and the separating sealing groove 181 extends along the circumferential direction of the mounting bracket 169. The dishwasher 1 also includes a separating seal 193, which is embedded in the separating sealing groove 181. The separating seal 193 can be made of rubber or silicone. This effectively solves the sealing problem between the separator 16 and the inner tub 15, preventing water leakage between the upper washing cavity 1531 and the lower washing cavity 1532, and improving the washing effect. In addition, the separating sealing groove 181 can be formed by the mounting bracket 169 and the inner tub 15, which is simple in structure. The assembly of the separating seal 193, the separator 16, and the inner tub 15 is more compact, effectively utilizing the limited space of the washing cavity 153. This allows for the rational layout of other components within the limited washing cavity 153, improving the overall performance of the dishwasher 1.

[0187] Preferably, please refer to the following for details. Figure 24 The aforementioned mounting bracket 169 includes a fixing part 1691, a spacer part 1692, and a support part 1693. The fixing part 1691 is spaced apart from the inner wall of the washing cavity 153. The fixing part 1691 extends towards the upper washing cavity 1531 and parallel to the inner wall of the cavity. The spacer part 1692 extends towards the lower washing cavity 1532 and parallel to the inner wall of the cavity, so that the contact area between the spacer part 1692 and the inner wall of the cavity is larger. Thus, the spacer part 1692 can fit tightly against the inner wall of the cavity. The spacer part 1692 is fixedly connected to the inner liner 15. The fixed connection here should be understood as the spacer part 1692 being welded and / or glued to the inner wall of the cavity, or it can be the spacer part 1692 being bolted to the inner wall of the cavity. Furthermore, both the fixing part 1691 and the spacer part 1692 are fixedly connected to the support part 1693. The fixed connection here is preferably integrally formed, and the fixing part 1691, the support part 1693, and the inner wall of the washing cavity 153 cooperate to form the above-mentioned separation sealing groove 181.

[0188] Thus, the fixing part 1691 makes the connection between the mounting bracket 169 and the wall of the washing cavity 153 more stable, providing a solid support foundation for the entire separator 16. It can effectively resist external forces from the direction of the lower washing cavity 1532, such as water flow impact and the weight of the washed items, preventing the separator 160 from shaking, shifting, or deforming, and ensuring that the upper washing cavity 1531 and the lower washing cavity 1532 always maintain a stable separation state. At the same time, since the partition part 1692 fits tightly against the inner wall of the cavity, it can fill any gaps that may exist. Together with the fixing part 1691, the support part 1693 to form the separation sealing groove 181 and the separation sealing element 193, it plays a role in providing multiple sealing guarantees, reducing the risk of water leakage, maintaining the independence of each washing cavity, and improving the washing effect.

[0189] For further details, please refer to [link / reference]. Figure 24 The end of the partition 1692 away from the support 1693 is bent into a folded edge 1694, and the folded edge 1694 and the partition 1692 form an assembly groove 1695, which has a U-shaped groove structure. The partition plate 160 includes a carrier 1601 and a sliding body 1602. The carrier 1601 and the fixing part 1691 form the drainage groove 164, and the sliding body 1602 is inserted into the assembly groove 1695. The carrier 1601 is fixedly connected to the sliding body 1602. The fixed connection here preferably adopts a bending integral molding process to ensure the strength and stability of the overall structure of the partition plate 160, which helps to enhance the impact resistance of the partition plate 160 during the washing process. Understandably, the water cup 17 is installed and fixed on the carrier 1601.

[0190] This setup will have the following unexpected technical effects:

[0191] Firstly, the sliding insert 1602 of the partition plate 160 is inserted into the assembly groove 1695 formed by the folded edge 1694 of the spacer portion 1692, making the installation of the partition plate 160 simple and direct, requiring no complicated tools or additional connectors, simplifying the assembly process, greatly improving assembly efficiency, and reducing assembly difficulty. If the partition plate 160 needs to be inspected, replaced, or disassembled for cleaning, the sliding insert 1602 can be easily pulled out of the assembly groove 1695 to perform the corresponding operation, realizing the convenience and flexibility of the partition plate 160 in assembly.

[0192] Secondly, the carrier 1601 and the fixing part 1691 can be configured as a drainage groove 164, and the two are closely matched to effectively prevent water from leaking to other parts, better ensure the normal operation of the dishwasher 1, extend the service life of the dishwasher 1, and at the same time, effectively guide the wastewater generated during the washing process to the designated location to achieve smooth and fast drainage, reduce water accumulation and residue, improve the washing effect, and avoid bacterial growth and odor caused by water accumulation.

[0193] It should be noted that, for details please refer to [link / reference]. Figure 24 Along the direction perpendicular to the support portion 1693 and towards the carrier 1601, the folded edge dimension Ls of the folded edge 1694 is not less than 3mm and not more than 20mm. This ensures that the folded edge 1694 possesses sufficient strength and rigidity, providing adequate support after the sliding body 1602 is inserted into the assembly slot 1695. This prevents deformation due to stress, ensures the stability of the connection between the partition plate 160 and the partition portion 1692, maintains the stability of the dishwasher 1's partition structure, and prevents the partition plate 160 from shaking during washing due to loose connections, thus affecting the washing effect. It also avoids the problem of a bulky structure and wasted materials due to an excessively large folded edge dimension Ls, and prevents negative impacts on the overall structural stability due to increased weight and volume, ensuring that the force is evenly distributed throughout the structure.

[0194] If the folded edge dimension Ls < 3mm, making the folded edge 1694 too small, it will not only easily lead to insufficient strength, but also easily deform under stress during the insertion of the sliding body 1602 and daily use. This will result in an unstable connection between the partition plate 160 and the partition part 1692, potentially causing the partition plate 160 to loosen or shift, affecting the normal operation of the dishwasher 1. Simultaneously, an overly narrow assembly slot 1695 will make it difficult to insert the sliding body 1602, or even prevent it from being inserted, increasing assembly difficulty, reducing assembly efficiency, and hindering subsequent disassembly and maintenance. Furthermore, it is not conducive to bending and forming, increasing the difficulty of the bending process. Conversely, if the folded edge dimension Ls > 20mm, making the folded edge 1694 too large, it will not only increase material costs and weight, but may also cause the center of gravity of the entire structure to shift, affecting the stability of the equipment. An excessively large folded edge will result in an oversized assembly slot 1695, potentially occupying too much space, affecting the layout and normal operation of other components, and also increasing the contact area between the sliding body 1602 and the assembly slot 1695, increasing resistance during the insertion process.

[0195] It should also be noted that, for details please refer to [link / reference]. Figure 24Along the direction perpendicular to the support portion 1693 and facing the washing chamber 1531, the distance between the end of the fixing portion 1691 away from the support portion 1693 and the support portion 1693 is the length dimension L1 of the fixing portion 1691, which is not less than 5mm and not more than 25mm. This ensures that the fixing portion 1691 has sufficient structural strength, facilitating the cooperation between the fixing portion 1691, the support portion 1693, and the wall of the washing chamber 153 to form a stable separating sealing groove 181, allowing the separating sealing element 193 to be better embedded and achieve a good sealing effect.

[0196] If the length L1 is less than 5mm, the fixing part 1691 is too short, resulting in insufficient strength. It cannot form an effective sealing groove 181 with the support part 1693 and the wall of the washing cavity 153, leading to decreased sealing performance, leakage, and reduced washing effect. Furthermore, it is difficult to bend and form the fixing part 1691, increasing the difficulty of bending production. Conversely, if the length L1 is greater than 25mm, an excessively long fixing part 1691 will complicate the structure, increasing material costs and weight. It will also occupy too much space in the washing cavity 153, affecting the installation and layout of other components and hindering the proper placement of laundry items, potentially reducing the utilization rate of the washing space. Moreover, an excessively long fixing part 1691 is more prone to bending and deformation under stress, further affecting structural stability.

[0197] Preferably, please refer to the following for details. Figure 23 and Figure 24 As shown, the inner tub 15 has a protruding limiting rib 154 protruding into the washing cavity 153. At this time, the limiting rib 154 is located above the separating sealing groove 181. When the separating seal 193 is assembled and embedded into the separating sealing groove 181, part of the separating seal 193 protrudes from the separating sealing groove 181 and abuts against the limiting rib 154. Thus, when the separating seal 193 partially protrudes from the separating sealing groove 181 and abuts against the limiting rib 154, an additional sealing barrier is formed. During the washing process, even if a small amount of water seeps into the vicinity of the separating sealing groove 181, it will be blocked by the limiting rib 154 and the protruding part of the separating seal 193, preventing further leakage between the upper washing cavity 1531 and the lower washing cavity 1532, further enhancing the sealing performance of the dishwasher 1, effectively preventing water leakage, and ensuring the washing effect. Simultaneously, during assembly, the limiting rib 154 can serve as a positioning marker. When the installer assembles the partition seal 193 into the partition seal groove 181, the partition seal 193 abuts against the limiting rib 154, which makes it clear that the partition seal 193 has been installed in place, facilitating operation and improving assembly efficiency.

[0198] It should be noted that, for details please refer to [link / reference]. Figure 24The aforementioned separating seal 193 includes a seal body 1931. The height he of the rubber strip of the seal body 1931 is greater than its length L1, and the height he is not less than 6mm and not more than 30mm. The height he is the length of the seal body 1931 in the direction perpendicular to the support portion 1693. This ensures that the separating seal 193 protrudes from the separating sealing groove 181 and forms a tighter contact with the limiting rib 154, effectively preventing water leakage. Simultaneously, it better adapts to various conditions during the operation of the dishwasher 1. When the dishwasher 1 vibrates or is subjected to external impact, the elastic deformation of the separating seal 193 itself can buffer the impact, maintain the sealing effect, ensure the stability of the separating seal 193, and guarantee the normal operation of the dishwasher 1.

[0199] If the height of the rubber strip he is less than 6mm, the sealing body 1931 is too short and cannot effectively abut against the limiting rib 154, significantly reducing the sealing effect. This can easily lead to water leakage during washing, affecting the normal use of the equipment and potentially damaging other internal components. Furthermore, a shorter sealing body 1931 lacks sufficient cushioning under external force, failing to effectively maintain the stability of the partition structure. Conversely, if the rubber strip height he is greater than 30mm, an excessively tall sealing body 1931 will result in material waste and increased costs. An excessively tall sealing body 1931 is also prone to excessive deformation under pressure, potentially leading to bending, breakage, or even seal failure.

[0200] It should also be noted that, for details please refer to [link / reference]. Figure 24 The aforementioned separating seal 193 also includes a rubber strip drainage section 1932, which extends obliquely from the end of the sealing body 1931 to the limiting rib 154. Specifically, the rubber strip drainage section 1932 is located at the end of the sealing body 1931 that protrudes from the separating sealing groove 181, and the rubber strip drainage section 1932 extends obliquely from the side near the fixing part 1691 toward the bottom of the limiting rib 154. The rubber strip drainage section 1932 is fixedly connected to the sealing body 1931, and the fixed connection here preferably adopts an integral molding process.

[0201] On the one hand, the rubber strip drainage section 1932 and the limiting rib 154 form a tight fit, achieving the purpose of the separating seal 193 and the limiting rib 154 abutting against each other to form a sealing barrier. On the other hand, the rubber strip drainage section 1932 can also guide water flow along its inclined surface into the drainage groove 164, preventing water from accumulating near the separating seal 193, further enhancing the waterproof effect, thereby improving the washing effect.

[0202] It should be noted that, for details please refer to [link / reference]. Figure 24The angle between the rubber strip drain section 1932 and the horizontal plane is ε, which is not less than 5° and not greater than 75°. This ensures that the rubber strip drain section 1932 has sufficient inclination to guide water flow and smoothly discharge waste, while preventing the drain section from being too steep to avoid excessive water flow velocity impacting the internal structure of the dishwasher 1. It also facilitates manufacturing and installation, ensuring the precise fit between the rubber strip drain section 1932 and the limiting rib 154. If ε < 5°, the slope of the rubber strip drain section 1932 is insufficient, water cannot drain smoothly and is prone to accumulating in the drain section, leading to decreased sealing performance. Conversely, if ε > 75°, the slope of the rubber strip drain section 1932 is too large, resulting in excessively fast water flow, which may impact the internal structure of the dishwasher 1 and increases manufacturing and installation difficulty.

[0203] It should also be noted that, for details please refer to [link / reference]. Figure 24 The distance between the fixing part 1691 and the inner wall of the washing cavity 153 is the groove width Bt of the separating sealing groove 181, which is not less than 3mm and not more than 20mm. This not only facilitates the bending and forming of the fixing part 1691, the support part 1693, and the spacer part 1692, but also ensures sufficient space for the separating seal 193 to be installed, guaranteeing its integrity and normal operation. It avoids problems such as difficulty in installation or deformation due to insufficient space, or loosening due to excessive space, thus affecting the sealing effect. However, when the groove width Bt < 3mm, the separating sealing groove 181 is too narrow, making it difficult to install the separating seal 193 properly. Even if it is installed with difficulty, it is easily deformed due to compression, failing to perform its normal sealing function and greatly increasing the risk of leakage. At the same time, it also increases the manufacturing difficulty of forming the support part 1693. When the groove width Bt > 20mm, the separating sealing groove 181 is too wide, and the separating seal 193 cannot tightly fill the groove. During the operation of the dishwasher 1, the separating seal 193 is prone to shaking and displacement in the separating sealing groove 181, which leads to the failure of the separating seal 193.

[0204] Furthermore, along the direction of the groove width, the width be of the rubber strip of the sealing body 1931 is greater than the groove width Bt. The wider sealing body 1931 can better fill the separating sealing groove 181, allowing the separating seal 193 to form an interference fit with the separating sealing groove 181. During the washing process, even when affected by external forces such as water flow impact and dishwasher 1 vibration, the separating seal 193 can always be tightly fitted to the groove wall of the separating sealing groove 181, effectively preventing water leakage and ensuring the sealing between the upper washing chamber 1531 and the lower washing chamber 1532, ensuring that the washing effect is not affected. At the same time, in the actual production process, there may be certain manufacturing errors in various components of the dishwasher 1, and the groove width Bt of the separating sealing groove 181 is difficult to be completely consistent. The rubber strip width be being greater than the groove width Bt can effectively compensate for these errors. Even when the groove width is slightly larger than the standard size, the wider rubber strip can still achieve a good seal, improving the product's versatility and stability.

[0205] It should be added that the width of the rubber strip be is not less than 4mm and not more than 25mm. This ensures that the separator seal 193 effectively fills the separator sealing groove 181 and avoids excessive compression and deformation of the separator seal 193, guaranteeing the sealing effect and preventing water leakage. It also avoids excessive waste of material for the separator seal 193. If the rubber strip width be < 4mm, the seal body 1931 is too narrow. When facing a groove width of at least 3mm Bt, it may not be able to completely fill the separator sealing groove 181, significantly reducing the sealing effect and making it prone to leakage during washing, affecting the normal use of the dishwasher 1 and reducing its performance. When the rubber strip width be > 25mm, the seal body 1931 is too wide, and it may be difficult to smoothly fit into the separator sealing groove 181, which is at most 20mm wide, during installation. Forced installation may cause excessive compression and deformation of the separator seal 193, affecting the sealing performance. Furthermore, an excessively wide partition seal 193 will increase material costs and may also damage the inner wall of the fixing part 1691 and the washing cavity 153 due to uneven stress, reducing the stability and service life of the dishwasher 1.

[0206] In addition, please see details. Figure 24 The separating seal 193 also includes a rubber strip extension 1933, which extends from the sealing body 1931 and is inclined along the center line of the sealing body 1931. The rubber strip extension 1933 is preferably inclined upward. Preferably, there are multiple rubber strip extensions 1933, which are evenly distributed along the center line of the sealing body 1931. The rubber strip extensions 1933 abut against the inner wall of the separating sealing groove 181. The rubber strip extensions 1933 are fixedly connected to the sealing body 1931. The fixed connection is preferably integrally formed.

[0207] This upward-sloping rubber strip extension 1933 provides a natural guide during the installation of the partition seal 193. When the partition seal 193 is placed into the partition sealing groove 181, the rubber strip extension 1933 first contacts the groove wall, and its inclined shape guides the partition seal 193 to slide accurately into the groove. Simultaneously, due to the elasticity of the rubber strip extension 1933, even with slight dimensional deviations in the partition sealing groove 181 during installation, the rubber strip extension 1933 can adaptively adjust through its own deformation. It can slightly bend or contract when pressed by the groove wall of the partition sealing groove 181, allowing the partition seal 193 to be smoothly installed in place, greatly reducing the alignment difficulty and time during installation, and improving installation efficiency.

[0208] It should be noted that the angle formed by the centerline of the rubber strip extension 1933 and the sealing body 1931 is θ, which is not less than 90° and not greater than 150°. This setting effectively ensures that the rubber strip extension 1933 remains relatively extended during installation, fully utilizing its guiding and self-adjusting functions, and forming good contact with the inner wall of the separating sealing groove 181, effectively guiding the separating sealing member 193 into place, while maintaining stable sealing performance during the operation of the dishwasher 1. When θ < 90°, the rubber strip extension 1933 is difficult to play an effective guiding role during installation, and the angle is too small to effectively abut against the groove wall, affecting the sealing effect. When θ > 150°, the rubber strip extension 1933 is too tilted, and it is easy to bend excessively in the groove during installation, or even break, affecting installation and use, and may also cause uneven stress on the rubber strip extension 1933, reducing the stability and service life of the separating sealing member 193.
